         OFFER TO EXCHANGE 6 7/8% SENIOR NOTES DUE 2007 WHICH HAVE BEEN

         6 7/8% SENIOR NOTES DUE 2007 WHICH HAVE NOT BEEN SO REGISTERED

        THE EXCHANGE OFFER WILL EXPIRE AT 5:00 P.M., NEW YORK CITY TIME,

                            ------------------------
 
    Louis Dreyfus Natural Gas Corp., an Oklahoma corporation (the "Company"),
hereby offers, upon the terms and subject to the conditions set forth in this
Prospectus (as defined) and the accompanying Letter of Transmittal (the "Letter
of Transmittal"), to exchange (the "Exchange Offer") its 6 7/8% Senior Notes due
2007 (the "Exchange Notes") which have been registered under the Securities Act
of 1933, as amended (the "Securities Act"), for an equal principal amount of its
outstanding 6 7/8% Senior Notes due 2007 which have not been so registered (the
"Existing Notes"), of which an aggregate principal amount of $200,000,000 is
outstanding as of the date hereof. The form and terms of each of the Exchange
Notes will be the same in all material respects as the form and terms of each of
the Existing Notes, except that (i) the Exchange Notes will be registered under
the Securities Act and hence will not bear legends restricting the transfer
thereof and (ii) holders of the Exchange Notes will not be entitled to certain
rights of holders of Existing Notes under the Registration Agreement dated as of
December 11, 1997 (the "Registration Agreement"), which will terminate upon
consummation of the Exchange Offer. See "The Exchange Offer--Purpose and Effect
of the Exchange Offer." Except as discussed below, the Exchange Notes will be
available only in book-entry form. The Company expects that the Exchange Notes
issued pursuant to the Exchange Offer will be issued in the form of one or more
fully registered global notes that will be deposited with, or on behalf of, The
Depository Trust Company ("DTC") and registered in the name of Cede & Co., as
its nominee. Beneficial interests in the global notes representing the Exchange
Notes will be shown on, and transfers thereof will be effected only through,
records maintained by DTC and its participants. After the initial issuance of
such global notes, Exchange Notes in certificated form will be issued in
exchange for the global notes only in accordance with the terms and conditions
set forth in the Indenture (as defined). See "Description of Exchange
Notes--Book-Entry; Delivery and Form" and "--Certificated Notes."
 
    The Existing Notes were issued and sold in a transaction exempt from the
registration requirements of the Securities Act and may not be offered or sold
in the United States unless so registered or pursuant to an applicable exemption
under the Securities Act. The Exchange Notes are being offered herewith in order
to satisfy certain obligations of the Company contained in the Registration
Agreement. Based on no-action letters issued by the staff of the Securities and
Exchange Commission (the "Commission") to third parties, the Company believes
that the Exchange Notes to be issued pursuant to the Exchange Offer may be
offered for resale, resold and otherwise transferred by holders thereof (other
than (i) a broker-dealer who purchases such Exchange Notes from the Company to
resell pursuant to Rule 144A or any other available exemption under the
Securities Act, or (ii) a person that is an "affiliate" of the Company within
the meaning of Rule 405 under the Securities Act), without compliance with the
registration and prospectus delivery provisions of the Securities Act, provided
that such Exchange Notes are acquired in the ordinary course of such holder's
business and such holders are not participating and have no arrangement with any
person to participate in the distribution of such Exchange Notes. However, the
Company has not sought a no-action letter with respect to the Exchange Offer and
there can be no assurance the staff of the Commission would make a similar
determination with respect to the Exchange Offer. Eligible holders wishing to
accept the Exchange Offer must represent to the Company that such conditions
have been met. Each broker-dealer that receives Exchange Notes for its own
account pursuant to the Exchange Offer must acknowledge that it will deliver a
prospectus in connection with any resale of such Exchange Notes. The Letter of
Transmittal states that by so acknowledging and by delivering a prospectus, a
broker-dealer will not be deemed to admit that it is an "underwriter" within the
meaning of the Securities Act. A broker-dealer may nonetheless be deemed to be
an "underwriter" under the Securities Act notwithstanding such disclaimer. This
Prospectus (as it may be amended or supplemented from time to time) may be used
by a broker-dealer in connection with resales of Exchange Notes received in
exchange for Existing Notes where such Existing Notes were acquired by such
broker-dealer as a result of market-making activities or other trading
activities. The Company has agreed that, for a period of 180 days (exclusive of
any period during which any stop order shall be in effect suspending the
effectiveness of the Registration Statement (as defined)) after the Expiration
Date (as defined), it will make this Prospectus available to any broker-dealer
for use in connection with any such resale. See "Plan of Distribution."

THESE SECURITIES HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE SECURITIES AND
EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION NOR HAS THE
    SECURITIES AND EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION
       PASSED UPON THE ACCURACY OR ADEQUACY OF THIS PROSPECTUS. ANY
          REPRESENTATION TO                THE CONTRARY IS A
                               CRIMINAL OFFENSE.
 
                           --------------------------
 
                 The date of this Prospectus is         , 1998.
<PAGE>
    Holders of Existing Notes whose Existing Notes are not tendered and accepted
in the Exchange Offer will continue to hold such Existing Notes and will be
entitled to all the rights and preferences and will be subject to the
limitations applicable thereto under the Indenture (as defined) governing the
Existing Notes and the Exchange Notes (the Existing Notes and the Exchange Notes
are sometimes referred to herein collectively as the "Notes"). Following
consummation of the Exchange Offer, the holders of Existing Notes will continue
to be subject to the existing restrictions upon transfer thereof and the Company
will have no further obligation to such holders to provide for the registration
under the Securities Act of the Existing Notes held by them. The Exchange Notes
will evidence the same debt as the Existing Notes and will be entitled to the
benefits of the indenture dated December 11, 1997 (the "Indenture") governing
the Notes. The Notes will bear interest at the rate of 6 7/8% per annum, payable
semi-annually on June 1 and December 1, commencing June 1, 1998. The Notes will
mature on December 1, 2007. The Company may redeem the Notes, in whole or in
part, at any time, at the redemption prices set forth herein, together with
accrued and unpaid interest, if any, to the date of redemption. The Notes will
not be subject to any sinking fund requirement. See "Description of Exchange
Notes--Optional Redemption." Other than restrictive covenants, including
limitations on liens and sale and leaseback transactions, the Indenture does not
contain any provisions that afford holders of the Notes protection in the event
of a highly leveraged or other transaction that may adversely affect such
holders. See "Description of Exchange Notes."
 
    The Existing Notes are and the Exchange Notes will be senior unsecured
obligations of the Company. The Existing Notes rank and the Exchange Notes will
rank PARI PASSU in right of payment with all existing and future senior
indebtedness of the Company and rank or will rank senior in right of payment to
any existing or future subordinated indebtedness of the Company. The Company
currently has outstanding $100 million principal amount of 9 1/4% Senior
Subordinated Notes due 2004, which are subordinate to the Notes. The Company's
borrowings under its $450 million unsecured revolving bank credit facility (the
"Bank Credit Facility") rank PARI PASSU with the Notes. As of December 31, 1997,
the Company had $261 million principal amount of borrowings outstanding under
the Bank Credit Facility. See "Capitalization." The Notes will be effectively
subordinated to any secured debt of the Company to the extent of the assets
serving as security therefor.
 
    The Exchange Offer is not conditioned on any minimum aggregate principal
amount of Existing Notes being tendered for exchange. The Company will accept
for exchange any and all validly tendered Existing Notes not withdrawn prior to
5:00 p.m., New York City time, on             , 1998 unless extended by the
Company (the "Expiration Date"). Tenders of Existing Notes may be withdrawn at
any time prior to the Expiration Date. The Exchange Offer is subject to certain
customary conditions. See "The Exchange Offer--Conditions." The Company has
agreed to pay all expenses incident to the Exchange Offer. The Company will not
receive any proceeds from the Exchange Offer.
 
    The Existing Notes constitute securities for which there is no established
trading market. Any Existing Notes not tendered and accepted in the Exchange
Offer will remain outstanding. The Company does not currently intend to list the
Exchange Notes on any securities exchange. To the extent that any Existing Notes
are tendered and accepted in the Exchange Offer, a holder's ability to sell
untendered Existing Notes could be adversely affected. No assurances can be
given as to the liquidity of the trading market for either the Existing Notes or
the Exchange Notes.
 
THE EXCHANGE OFFER IS NOT BEING MADE TO, NOR WILL THE COMPANY ACCEPT SURRENDERS
FOR EXCHANGE FROM, HOLDERS OF EXISTING NOTES IN ANY JURISDICTION IN WHICH THE
EXCHANGE OFFER OR THE ACCEPTANCE THEREOF WOULD NOT BE IN COMPLIANCE WITH THE
SECURITIES OR BLUE SKY LAWS OF SUCH JURISDICTION.

                                  THE COMPANY
 
    Louis Dreyfus Natural Gas is a large independent energy company engaged in
the acquisition, development and exploration of natural gas and oil properties,
primarily in Texas, Oklahoma and New Mexico, and in the production and marketing
of natural gas and crude oil.
 
    The address of the Company's principal executive offices is 14000 Quail
Springs Parkway, Suite 600, Oklahoma City, OK 73134, and its telephone number is
(405) 749-1300.
 
RECENT DEVELOPMENTS
 
    AMERICAN ACQUISITION.  On October 14, 1997, the Company completed the
acquisition (the "American Acquisition") of American Exploration Company
("American"), a publicly-held independent energy company with exploration and
development activities focused primarily in South Texas, Texas State Waters, the
Cotton Valley Reef Trend in East Texas and the Smackover Trend in Arkansas. The
acquisition consideration paid to the shareholders of American consisted of 11.3
million shares of Company common stock and $47 million of cash. In addition,
$116 million of long-term debt and preferred stock having a liquidation value of
$20 million were assumed by the Company in the transaction. Based on the $23.06
closing price of Company common stock on October 14, 1997, the total
consideration paid plus long-term debt and preferred stock assumed was $444
million.
 
    Over the past two years, the Company and American worked together closely on
certain projects. Through this association, each company gained an appreciation
for their complementary strengths. The Company's strengths include a
substantial, long-lived reserve base, a large inventory of low-risk development
drilling locations and strong oil and gas operating and product marketing
capabilities. American's strengths included a high quality, although
shorter-lived, reserve base, a substantial inventory of high potential
exploratory prospects and strong prospect generating and technical skills.
 
    The American Acquisition combines the complementary strengths of each
organization and creates a larger and more balanced independent exploration and
production company with pro forma proved reserves as of December 31, 1996
totaling approximately 1.2 Tcfe, of which 82% was natural gas and 82% was
developed. The estimated future net revenues of these reserves as of December
31, 1996 was $3.0 billion with a Present Value of $1.5 billion. Pro forma daily
production for the first nine months of 1997 was 304 MMcfe per day resulting in
a Reserve Life Index of 11.2 years. The addition of American's proved reserves,
which increased the Company's proved reserves by 26%, improves the Company's
property mix and operating cash flows available for reinvestment and debt
service.
 
    As a result of the American Acquisition, the Company has a stronger balance
sheet, higher operating cash flows and a more diversified property base, as well
as significant growth potential through a balance of low-risk development (an
estimated 1,350 potential development locations) and higher-risk exploration
drilling.
 
    1997 FINANCIAL RESULTS.  On February 3, 1998, the Company announced its
results of operations for the fourth quarter and year ended December 31, 1997.
 
    Excluding the effects of a fourth-quarter impairment charge, the Company
reported net income of $31.1 million, or $1.03 per share, on total revenue of
$232.9 million for the year ended December 31, 1997. This compares with net
income of $21.1 million, or $.76 per share, on total revenue of $189.5 million
for
 
                                       6
<PAGE>
1996. The Company reported cash flows from operating activities (before working
capital changes) for the year ended December 31, 1997 of $127.1 million, which
compares to $101.0 million for 1996, an increase of 26%. Cash flows from
operating activities after consideration of working capital changes were $129.8
million for the year ended December 31, 1997 compared to $101.8 million for
1996. The 1997 increase in revenues and operating cash flows was achieved
primarily through growth in oil and gas production and higher oil and gas
prices. The Company reported a net loss of $16.1 million, or $.53 per share,
after the effects of a $75.2 million non-cash impairment charge ($47.1 million
after tax), substantially all of which was recognized as anticipated in
connection with the American Acquisition.
 
    Excluding the non-cash impairment charge, the Company reported net income of
$8.4 million, or $.23 per share, on total revenue of $80.1 million for the
quarter ended December 31, 1997. This compares to net income of $7.8 million, or
$.28 per share, on total revenue of $54.9 million for the fourth quarter of
1996. Cash flows from operating activities (before changes in working capital)
for the fourth quarter of 1997 were sharply higher, increasing 43% to $46.8
million compared to $32.6 million for the fourth quarter of 1996. Cash flows
from operating activities after consideration of working capital changes were
$49.4 million for the fourth quarter of 1997 compared to $32.7 million for the
fourth quarter of 1996. This improvement was primarily attributable to higher
oil and gas production as a result of the American Acquisition. The Company
reported a net loss of $38.7 million, or $1.03 per share, after the effects of
the acquisition impairment charge.
 
GENERAL
 
    The Company has grown its production and reserves through both acquisitions
and drilling operations. Since 1991, in addition to the American Acquisition,
the Company has completed a significant number of reserve acquisitions including
three acquisitions ranging in size from $87 million to $180 million. Through its
acquisition and leasing programs, the Company has accumulated, as of September
30, 1997 on a pro forma basis, interests in approximately 4.5 million gross (1.3
million net) acres on which to conduct future drilling operations. During the
three years ended December 31, 1996, the Company drilled 745 gross (450 net)
wells with only 34 gross (14 net) dry holes.
 
    For the five-year period ended December 31, 1996 giving pro forma effect to
the American Acquisition, the Company's strategy of growth through acquisitions
and drilling has enabled the Company to realize compound annual growth rates in
production, proved reserves and cash flows provided by operating activities of
39%, 35% and 62%, respectively.
 
BUSINESS STRATEGY
 
    The Company's business strategy is to achieve consistent growth in
production, reserves and operating cash flows. The Company implements this
strategy through the following:
 
    GROWTH THROUGH DRILLING.  In 1994, 1995 and 1996, the Company replaced 116%,
120% and 153%, respectively, of its production, adding 251 Bcfe of proved
reserves through the drill bit (including revisions of previous estimates).
During this three year period, finding and development costs of reserves added
through drilling averaged $.95 per Mcfe. The drilling program is the source of
the Company's internally generated growth and is designed to provide a balance
between lower risk development drilling in areas where multiple productive oil
and gas bearing formations are likely to be encountered, thus reducing dry hole
risk, and higher risk exploration drilling which provides the potential for
greater production and reserve growth. On a pro forma basis, approximately $132
million, or 61%, of the Company's 1997 drilling budget has been allocated to
development activities and the balance of $83 million, or 39%, has been
allocated to exploration activities. Subsequent to the American Acquisition, the
Company has a combined staff of 50 geologists, geophysicists and reservoir and
operations engineers with extensive experience in the areas where its reserves
and acreage are located. The staff also has extensive experience in the use of
 
                                       7
<PAGE>
advanced technologies, including 3-D seismic analysis, computer aided mapping
and reservoir simulation modeling.
 
    STRATEGIC ACQUISITIONS.  Since January 1, 1990, the Company has completed
proved reserve acquisitions, including the American Acquisition, aggregating
approximately $1 billion and 1.3 Tcfe. The acquisitions have been geographically
concentrated in core areas where the Company possesses considerable expertise
and realizes economies of scale. The Company principally targets acquisitions
which have further development and exploration potential, have a high degree of
operatorship in order to better control the future exploitation of the
properties and can be integrated with minimal incremental administrative cost.
The Company currently operates 70% of its production.
 
    LARGE PROPERTY BASE.  The Company owns interests in approximately 10,000
wells primarily located in Texas, Oklahoma and New Mexico. Due to the Company's
large property base, the loss of production due to unexpected well problems is
minimized while the opportunities to generate positive results through the
application of improved production technologies is enhanced. The Company has
five district offices located central to its principal areas and employs 174
pumpers and other field personnel to provide onsite management of its
properties.
 
    PRICE RISK MANAGEMENT.  The Company manages a portion of the risks
associated with decreases in prices of natural gas and, to a lesser extent,
crude oil through long-term fixed-price physical delivery contracts and
financial contracts ("Fixed-Price Contracts"). These Fixed-Price Contracts
provide a base of predictable cash flows for a portion of the Company's natural
gas and oil sales. Since 1990 through September 30, 1997, the Company has
generated $40 million in additional operating profits through its price risk
management strategies. At September 30, 1997, the pre-tax present value
(discounted at 10%) of the future net revenues for the Company's Fixed-Price
Contracts, based on the differences between contract prices and forward market
prices, was approximately $153 million. Since April 1996, the Company has not
entered into Fixed-Price Contracts with a term in excess of 12 months due to a
reluctance to sell into the prevailing forward market in which prices trend down
or are essentially flat over the next several years. For the first nine months
of 1997, 56% of the Company's production was hedged by Fixed-Price Contracts.

                                      Securities Act. See "The Exchange Offer." The

                                      Based on no-action letters issued by the staff of the
                                      Commission to third parties with respect to similar
                                      transactions, including "Exxon Capital Holdings
                                      Corporation" (available May 13, 1988) and "Morgan

                                      and similar no-action letters, the Company believes
                                      that the Exchange Notes issued pursuant to the
                                      Exchange Offer in exchange for Existing Notes may be
                                      offered for resale, resold and otherwise transferred
                                      by holders thereof (other than (i) a broker-dealer
                                      who purchases such Exchange Notes from the Company to
                                      resell pursuant to Rule 144A or any other available
                                      exemption under the Securities Act, or (ii) a person
                                      that is an "affiliate" of the Company within the

                                      delivery requirements of the Securities Act, provided
                                      that such Exchange Notes are acquired in the ordinary
                                      course of such holder's business and such holders are
                                      not engaged in, have no arrangement or understanding

                                      to engage in, any distribution of the Exchange Notes.
                                      However, the Company has not sought a no-action

                                      can be no assurance that the staff of the Commission
                                      would make a similar determination with respect to
                                      the Exchange Offer. Each holder of Exchange Notes,
                                      other than a broker-dealer, must represent that such
                                      conditions have been met. In addition, each
                                      broker-dealer that receives Exchange Notes for its
                                      own account pursuant to the Exchange Offer must

(1) The unaudited pro forma income statement data, statement of cash flows data
    and other financial data for the year ended December 31, 1996 and for the
    nine months ended September 30, 1997 give effect to the American Acquisition
    as if it had occurred on January 1, 1996. The unaudited pro forma balance
    sheet data as of September 30, 1997 gives effect to the American Acquisition
    as if it had occurred on September 30, 1997. Such pro forma data has been
    prepared pursuant to regulations prescribed by the Commission. The unaudited
    pro forma income statement data, statement of cash flows data and other
    financial data do not consider the effects of the cost reduction and
    financing plans of management being implemented following the American
    Acquisition, nor does such data include the effects of certain purchase
    accounting adjustments. The estimated combined financial impact of such
    plans and purchase accounting adjustments if included in the pro forma
    income statements would be an increase in pro forma pretax earnings of $18.8
    million and $12.1 million for the year ended December 31, 1996 and the nine
    months ended September 30, 1997, respectively.
 
(2) Other income (loss) for the nine months ended September 30, 1997 includes an
    $8.5 million gain recognized upon the sale of a non-core West Texas
    waterflood property in January 1997.
 
(3) The 1994 impairment was recorded in connection with the sale of
    approximately one-half of the Company's ownership in an offshore property.
    The 1995 impairment was recorded in connection with the adoption of SFAS No.
    121, "Accounting for the Impairment of Long-Lived Assets and Long-Lived
    Assets to be Disposed Of." Pro forma amounts do not include a one time
    impairment charge to be recorded in connection with the American Acquisition
    estimated as of September 30, 1997 to be $72.9 million.
 
(4) EBITDAX is defined herein as income before interest, income taxes,
    depreciation, depletion and amortization, impairments and exploration costs.
    The Company believes that EBITDAX is a financial measure commonly used in
    the oil and gas industry as an indicator of a company's ability to service
    and incur debt. However, EBITDAX should not be considered in isolation or as
    a substitute for net income, cash flows provided by operating activities or
    other data prepared in accordance with generally accepted accounting
    principles, or as a measure of a company's profitability or liquidity.
    EBITDAX as presented herein may not be comparable to other similarly titled
    measures of other companies.
 
(5) For purposes of calculating the ratio of earnings to fixed charges, earnings
    represents net income before income taxes plus fixed charges, less
    capitalized interest. Fixed charges consist of interest expense, including
    amortization of debt discount and financing costs, capitalized interest and
    the portion of rental expense which the Company believes is representative
    of the interest component of rental expense.

                SELECTED HISTORICAL AND PRO FORMA RESERVES DATA
 
    The following table sets forth information regarding estimated proved
reserves of the Company as of the dates indicated and the estimated pro forma
proved reserves of the Company as of December 31, 1996 giving effect to the
American Acquisition. Estimated recoverable proved reserves have been determined
without regard to any economic benefit that may be derived from Fixed-Price
Contracts. Such calculations were prepared using standard geological and
engineering methods generally accepted by the petroleum industry and in
accordance with Commission guidelines. Future net revenue is estimated using oil
and gas prices in effect as of the end of each respective year with price
escalations permitted only for those properties that have wellhead contracts
allowing specific increases. Estimated future operating costs are based on
historical operating costs incurred. The amounts shown do not give effect to
indirect expenses such as general and administrative expenses, debt service,
future income tax expense or to depletion, depreciation and amortization.

                                USE OF PROCEEDS
 
    The Exchange Offer is intended to satisfy certain of the Company's
obligations under the Registration Agreement. In consideration for issuing the
Exchange Notes contemplated in this Prospectus, the Company will exchange
Existing Notes (in a like principal amount), the form and terms of which are the
same as the form and terms of such Existing Notes, except as otherwise described
herein. The Existing Notes surrendered in exchange for Exchange Notes will be
retired and canceled and cannot be reissued. Accordingly, issuance of the
Exchange Notes will not result in any increase or decrease in the indebtedness
of the Company. As such, no effect has been given to the Exchange Offer in the
capitalization table. The Company will not receive any proceeds from the
Exchange Offer. The net proceeds to the Company from the offering of Existing
Notes on December 11, 1997 (the "Existing Notes Offering") were approximately
$197 million (after deduction of discounts to the Initial Purchasers and fees
and expenses relating to such Offering). The net proceeds of the Existing Notes
Offering were used to repay indebtedness incurred and assumed in connection with
the American Acquisition and other amounts outstanding under the Bank Credit
Facility. See "Capitalization." Bank of Montreal, an affiliate of Nesbitt Burns
Securities Inc., The Chase Manhattan Bank, an affiliate of Chase Securities
Inc., and NationsBank of Texas, N.A., an affiliate of NationsBanc Montgomery
Securities, Inc., are agent banks under the Bank Credit Facility and received
their respective proportionate shares of repayment by the Company of the
borrowings outstanding under the Bank Credit Facility from the net proceeds of
the Existing Notes Offering.
 
    In connection with the American Acquisition, the Company entered into a new
Bank Credit Facility that initially provided for an unsecured committed line of
credit of $550 million which terminates on October 14, 2002. In connection with
the issuance of the Existing Notes, the Company reduced the Bank Credit Facility
commitment to $450 million. As of December 31, 1997, the Company had $261
million principal amount of borrowings outstanding under the Bank Credit
Facility. Availability of loans under the Bank Credit Facility is not subject to
a borrowing base requirement unless the Company's long-term senior unsecured
debt is rated less than BBB- by Standard & Poor's Ratings Services and less than
Baa3 by Moody's Investors Service and the majority in interest of the lenders
elect to implement a borrowing base requirement. The Bank Credit Facility limits
the amount of the Company's Debt (as defined therein) to $700 million of which
no more than $625 million may be Senior Debt (as defined therein), prohibits the
Company from granting any liens or mortgages on its properties (subject to
certain exceptions), requires that the Company maintain a Tangible Net Worth (as
defined therein) of at least $400 million plus 50% of the proceeds of any equity
offerings and 50% of consolidated net income (for each quarter for which net
income is greater than zero beginning with the quarter ending December 31, 1997)
and requires the Company to maintain a Funded Debt Ratio (ratio of long-term
Debt to EBITDAX as defined therein) of no more than 4.00 to 1.00. As a result of
the $700 million limitation on Company Debt, the maximum amount that the Company
will be permitted to borrow under the Bank Credit Facility is approximately $400
million for so long as the Notes and the Company's 9 1/4% Senior Subordinated
Notes due 2004 remain outstanding. As of December 31, 1997, the Bank Credit
Facility had an effective interest rate for borrowings of 6.3% per annum, after
giving effect to interest rate swaps.

                                  THE COMPANY
 
    Louis Dreyfus Natural Gas is a large independent energy company engaged in
the acquisition, development and exploration of natural gas and oil properties,
primarily in Texas, Oklahoma and New Mexico, and in the production and marketing
of natural gas and crude oil.
 
RECENT DEVELOPMENTS
 
    AMERICAN ACQUISITION.  On October 14, 1997, the Company completed the
acquisition of American, a publicly-held independent energy company with
exploration and development activities focused primarily in South Texas, Texas
State Waters, the Cotton Valley Reef Trend in East Texas and the Smackover Trend
in Arkansas. The acquisition consideration paid to the shareholders of American
consisted of 11.3 million shares of Company common stock and $47 million of
cash. In addition, $116 million of long-term debt and preferred stock having a
liquidation value of $20 million were assumed by the Company in the transaction.
Based on the $23.06 closing price of Company common stock on October 14, 1997,
the total consideration paid plus long-term debt and preferred stock assumed was
$444 million.
 
    Over the past two years, the Company and American worked together closely on
certain projects. Through this association, each company gained an appreciation
for their complementary strengths. The Company's strengths include a
substantial, long-lived reserve base, a large inventory of low-risk development
drilling locations and strong oil and gas operating and product marketing
capabilities. American's strengths included a high quality, although
shorter-lived, reserve base, a substantial inventory of high potential
exploratory prospects and strong prospect generating and technical skills.
 
    The American Acquisition combines the complementary strengths of each
organization and creates a larger and more balanced independent exploration and
production company with pro forma proved reserves as of December 31, 1996
totaling approximately 1.2 Tcfe of which 82% was natural gas and 82% was
developed. The estimated future net revenues of these reserves as of December
31, 1996 was $3.0 billion with a Present Value of $1.5 billion. Pro forma daily
production for the first nine months of 1997 was 304 MMcfe per day resulting in
a Reserve Life Index of 11.2 years. The addition of American's proved reserves,
which increased the Company's proved reserves by 26%, improves the Company's
property mix and operating cash flows available for reinvestment and debt
service.
 
    As a result of the American Acquisition, the Company has a stronger balance
sheet, higher operating cash flows and a more diversified property base, as well
as significant growth potential through a balance of low-risk development (an
estimated 1,350 potential development locations) and higher-risk exploration
drilling.
 
    1997 FINANCIAL RESULTS.  On February 3, 1998, the Company announced its
results of operations for the fourth quarter and year ended December 31, 1997.
 
    Excluding the effects of a fourth-quarter impairment charge, the Company
reported net income of $31.1 million, or $1.03 per share, on total revenue of
$232.9 million for the year ended December 31, 1997. This compares with net
income of $21.1 million, or $.76 per share, on total revenue of $189.5 million
for 1996. The Company reported cash flows from operating activities (before
working capital changes) for the year ended December 31, 1997 of $127.1 million,
which compares to $101.0 million for 1996, an increase of 26%. Cash flows from
operating activities after consideration of working capital changes were $129.8
million for the year ended December 31, 1997 compared to $101.8 million for
1996. The 1997 increase in revenues and operating cash flows was achieved
primarily through growth in oil and gas production and higher oil and gas
prices. The Company reported a net loss of $16.1 million, or $.53 per share,
after the effects of a $75.2 million non-cash impairment charge ($47.1 million
after tax), substantially all of which was recognized as anticipated in
connection with the American Acquisition.
 
    Excluding the non-cash impairment charge, the Company reported net income of
$8.4 million, or $.23 per share, on total revenue of $80.1 million for the
quarter ended December 31, 1997. This compares to
 
                                       20
<PAGE>
net income of $7.8 million, or $.28 per share, on total revenue of $54.9 million
for the fourth quarter of 1996. Cash flows from operating activities (before
changes in working capital) for the fourth quarter of 1997 were sharply higher,
increasing 43% to $46.8 million compared to $32.6 million for the fourth quarter
of 1996. Cash flows from operating activities after consideration of working
capital changes were $49.4 million for the fourth quarter of 1997 compared to
$32.7 million for the fourth quarter of 1996. This improvement was primarily
attributable to higher oil and gas production as a result of the American
Acquisition. The Company reported a net loss of $38.7 million, or $1.03 per
share, after the effects of the acquisition impairment charge.
 
GENERAL
 
    The Company has grown its production and reserves through both acquisitions
and drilling operations. Since 1991, in addition to the American Acquisition,
the Company has completed a significant number of reserve acquisitions including
three acquisitions ranging in size from $87 million to $180 million. Through its
acquisition and leasing programs, the Company has accumulated, as of September
30, 1997 on a pro forma basis, interests in approximately 4.5 million gross (1.3
million net) acres on which to conduct future drilling operations. During the
three years ended December 31, 1996, the Company drilled 745 gross (450 net)
wells with only 34 gross (14 net) dry holes.
 
    For the five-year period ended December 31, 1996 giving pro forma effect to
the American Acquisition, the Company's strategy of growth through acquisitions
and drilling has enabled the Company to realize compound annual growth rates in
production, proved reserves and cash flows provided by operating activities of
39%, 35% and 62% respectively.
 
BUSINESS STRATEGY
 
    The Company's business strategy is to achieve consistent growth in
production, reserves and operating cash flows. The Company implements this
strategy through the following:
 
    GROWTH THROUGH DRILLING.  In 1994, 1995 and 1996, the Company replaced 116%,
120% and 153%, respectively, of its production, adding 251 Bcfe of proved
reserves through the drill bit (including revisions of previous estimates).
During this three year period, finding and development costs of reserves added
through drilling averaged $.95 per Mcfe. The drilling program is the source of
the Company's internally generated growth and is designed to provide a balance
between lower risk development drilling in areas where multiple productive oil
and gas bearing formations are likely to be encountered, thus reducing dry hole
risk, and higher risk exploration drilling which provides the potential for
greater production and reserve growth. On a pro forma basis, approximately $132
million, or 61%, of the Company's 1997 drilling budget has been allocated to
development activities and the balance of $83 million, or 39%, has been
allocated to exploration activities. Subsequent to the American Acquisition, the
Company has a combined staff of 50 geologists, geophysicists and reservoir and
operations engineers with extensive experience in the areas where its reserves
and acreage are located. The staff also has extensive experience in the use of
advanced technologies, including 3-D seismic analysis, computer aided mapping
and reservoir simulation modeling.
 
    STRATEGIC ACQUISITIONS.  Since January 1, 1990, the Company has completed
proved reserve acquisitions, including the American Acquisition, aggregating
approximately $1 billion and 1.3 Tcfe. The acquisitions have been geographically
concentrated in core areas where the Company possesses considerable expertise
and realizes economies of scale. The Company principally targets acquisitions
which have further development and exploration potential, have a high degree of
operatorship in order to better control the future exploitation of the
properties and can be integrated with minimal incremental administrative cost.
The Company currently operates 70% of its production.
 
                                       21
<PAGE>
    LARGE PROPERTY BASE.  The Company owns interests in approximately 10,000
wells primarily located in Texas, Oklahoma and New Mexico. Due to the Company's
large property base, the loss of production due to unexpected well problems is
minimized while the opportunities to generate positive results through the
application of improved production technologies is enhanced. The Company has
five district offices located central to its principal areas and employs 174
pumpers and other field personnel to provide onsite management of its
properties.
 
    PRICE RISK MANAGEMENT.  The Company manages a portion of the risks
associated with decreases in prices of natural gas and, to a lesser extent,
crude oil through Fixed-Price Contracts. The Company's Fixed-Price Contracts
provide a base of predictable cash flows for a portion of the Company's natural
gas and oil sales. Since 1990 through September 30, 1997, the Company has
generated $40 million in additional operating profits through its price risk
management strategies. At September 30, 1997, the pre-tax present value
(discounted at 10%) of the future net revenues for the Company's Fixed-Price
Contracts, based on the differences between contract prices and forward market
prices, was approximately $153 million. Since April 1996, the Company has not
entered into Fixed-Price Contracts with a term in excess of 12 months due to a
reluctance to sell into the prevailing forward market in which prices trend down
or are essentially flat over the next several years. For the first nine months
of 1997, 56% of the Company's production was hedged by Fixed-Price Contracts.

(4) Includes identified exploration leads.
 
    One of the Company's strategic objectives is to concentrate its activities
in core geographic areas in which it has experience and expertise. Such
geographic concentration permits the Company to achieve economies of scale in
connection with its drilling, production and marketing operations. There is
substantial synergy between the Company's oil and gas properties and the
properties acquired from American. Approximately 70% of the proved reserves
acquired in the American Acquisition are located in, or in close proximity to,
geographic locations in which the Company already owned proved reserves,
primarily in the Gulf Coast and Mid-Continent areas. In addition, the Company
will continue to pursue exploration projects in South Texas and in the Cotton
Valley Reef Trend in East Texas in which American and the Company were jointly
and independently participating before the American Acquisition.
 
                                       22

SONORA AREA
 
    The Sonora area, located on the northeast side of the Val Verde Basin of
West Central Texas is comprised of five fields, Sawyer, Shurley Ranch, MMW,
Aldwell Ranch and Whitehead. Production is predominantly from the Canyon
formation at depths ranging from 2,500 to 6,500 feet and the Strawn formation at
depths ranging from 5,000 to 9,000 feet. The Company has executed an aggressive
developmental drilling program in the Sonora area since 1993 and has significant
further opportunities through infill drilling (40 acre density) and recompletion
possibilities. For 1998, the Company plans to drill approximately 128 wells in
the Sonora area. The Company has identified 575 undrilled locations of which 111
have been assigned proved undeveloped reserves.
 
MID-CONTINENT AREA
 
    The Company's properties in the Mid-Continent area are primarily located in
and along the shelf of the Anadarko basin and in Southern Oklahoma. Production
is predominantly natural gas from numerous formations of Pennsylvanian and
Pre-Pennsylvanian aged rock. Productive depths range from 3,000 to 17,000 feet.
For 1998, the Company plans to drill approximately 112 wells in the
Mid-Continent area. The Company has identified 300 potential undrilled locations
of which 100 have been assigned proved undeveloped reserves.
 
    SON OF BEVO.  The Company is operator of and holds a 35% working interest in
this Texas Panhandle prospect. The target zone is the Upper Morrow at a depth at
10,000 feet. After evaluating the results of a 30 square mile 3-D seismic shoot,
the Company drilled five wells in the prospect, successfully completing four
wells with combined initial production rates of 9.5 MMcfe per day.
 
PERMIAN AREA
 
    The Company is actively involved in drilling development and exploration
wells in the Delaware basin of Southeast New Mexico and the Val Verde basin and
Spraberry trend of West Texas. The primary drilling objectives in this region
are the Delaware, Spraberry, Wolfcamp and Morrow sands. For 1998, the Company
plans to drill approximately 62 wells in the Permian area. The Company has
identified 500 undrilled locations, of which 221 have been assigned proved
undeveloped reserves.
 
    PITCHFORK RANCH.  The Company has an option to shoot seismic, acquire leases
and drill on approximately 140,000 acres of the Pitchfork Ranch located in North
Texas over the next three years. The Company will be operator with at least a
77.5% working interest. Target zones are the Tannehill sand at a depth of 4,500
feet and the Strawn lime at 5,500 feet. The Company has completed a 30 square
mile 3-D seismic project in the southern portion of the Pitchfork Ranch and, in
September 1997, commenced drilling the first of seven wells planned before
year-end. As of December 31, 1997, the Company had drilled three discoveries and
one development well with combined initial production of 450 Bbls per day.
 
GULF COAST AREA
 
    The Company's properties in the Gulf Coast area consist of varying interests
in the A.W.P. (Olmos) Field and the North Tatum Field in East Texas as well as
prospective Frio and Wilcox production in the Yoakum Gorge and Southwest Speaks
fields and pinnacle reef production in the Cotton Valley Reef Trend.
 
    YOAKUM GORGE.  The Yoakum Gorge prospect, in which the Company has
approximately an 87.5% working interest, is located in Lavaca County, Texas.
Earlier this year, the Company completed the acquisition of 150 square miles of
high-fold 3-D seismic data and began evaluating drilling opportunities on its
60,000 gross acres. The Company began drilling for the shallow targets in 1995
and has successfully completed 23 of 27 wells. The Company expects to drill
approximately 22 shallow wells during 1998. The first Lower Wilcox test was
recently drilled to a total depth of approximately 15,700 feet and logged
approximately 180 feet of pay in multiple Lower Wilcox sands. This well tested
at an initial production rate
 
                                       23
<PAGE>
in excess of 7 MMcfe per day from two of 12 productive sands. The Company owns a
100% working interest in this discovery.
 
    SOUTHWEST SPEAKS.  The Company has a 45% working interest in this Lower
Wilcox project, which is located east of Yoakum Gorge. Over the past 18 months,
the Company has drilled and completed four wells in this project and a fifth
well is currently being drilled. Current gross production is 21 MMcf per day
with additional volumes expected as the result of well stimulation plans and a
recent production facility upgrade.
 
    COTTON VALLEY REEF TREND.  The Company has varying interests in
approximately 100,000 acres in the Cotton Valley Reef Trend of East Texas. Last
month, the Company finished drilling operations on its initial pinnacle reef
target and logged approximately 240 feet of pay in the Cotton Valley Reef. The
Company owns a 62% working interest in this discovery with initial production
anticipated in the first quarter of 1998. The Company has acquired 3-D seismic
data on approximately 130 square miles within the Cotton Valley Reef Trend and
currently plans to drill two to four wells in the Cotton Valley Reef Trend
during 1998.
 
OFFSHORE AREA
 
    The Company owns varying interests in ten operated platforms in the Gulf of
Mexico in water depths ranging from 20 to 245 feet and owns varying interests in
eight nonoperated platforms. In the Gulf of Mexico, the Company's present
leasing and seismic acquisition activities are focused in Texas State Waters in
water depths ranging from 20 to 60 feet. With the advent of ocean bottom
cabling, high quality 3-D seismic data can now be acquired in the shallow
waters. The Company presently has acquired 2,100 miles of recently shot seismic
data. The Company plans to drill up to 11 prospects during 1998 and has
contracted for a drilling rig scheduled to commence drilling in February 1998.
 
    The Oil Pollution Act, as recently amended ("OPA"), requires the lessee or
permittee of the offshore area in which a covered offshore facility is located
to establish and maintain evidence of financial responsibility in the amount of
$35 million, which may be increased to $150 million in certain circumstances, to
cover liabilities related to an oil spill for which such person is statutorily
responsible. On March 25, 1997, the Minerals Management Service ("MMS") proposed
regulations to implement these financial responsibility requirements under OPA.
The Company cannot predict the final form of any financial responsibility
regulations that will be adopted by the MMS, but the impact of any such
regulations should not be any more adverse to the Company than it will be to
other similarly situated companies. OPA also subjects responsible parties to
strict, joint and several and potentially unlimited liability for removal costs
and certain other damages caused by an oil spill covered by the statute.
 
NIAGARA MOHAWK MATTERS
 
    The Company is a party to two Fixed-Price Contracts, both long-term physical
delivery contracts, with independent power producers ("IPPs") which sell
electrical power under firm, fixed-price contracts to Niagara Mohawk Corporation
("NIMO"), a New York state utility. The Company's Fixed-Price Contracts with
such IPPs covered an aggregate of 98 Bcf of natural gas as of September 30,
1997. At September 30, 1997, the net present value of the differential between
the fixed prices provided by these contracts and forward market prices, as
adjusted for basis and discounted at 10%, was $123 million, or 80% of the net
present value attributable to all of the Company's Fixed-Price Contracts. This
premium in the fixed prices in these contracts is not reflected in the Company's
financial statements until realized. Such contracts contributed $0.9 million to
1996 revenues. The ability of such IPPs to perform their obligations to the
Company is dependent on the continued performance by NIMO of its power purchase
obligations. NIMO has taken aggressive regulatory, judicial and contractual
actions in recent years seeking to curtail power purchase obligations, including
its obligations to the IPPs that are counterparties to the Company's Fixed-
 
                                       24
<PAGE>
Price Contracts described above, and has further stated that its future
financial prospects are dependent on its ability to resolve these obligations,
along with a number of other matters.
 
    On July 9, 1997, NIMO entered into a Master Restructuring Agreement (the
"MRA") with 16 IPPs, including the Company's counterparties. Pursuant to the
MRA, the power purchase agreements between NIMO and the IPPs would be
terminated, restated or amended, in exchange for an aggregate of $3.6 billion in
cash, $50 million in notes or cash, 46 million shares of NIMO common stock and
certain fixed-price swap contracts. The allocation of the consideration among
the IPPs has not been disclosed. The closing of the MRA is conditioned upon,
among other things, NIMO and the IPPs negotiating their individual restated and
amended contracts, the receipt of all regulatory approvals, the receipt of all
consents by third parties necessary for the transactions contemplated by the MRA
(including the termination of the existing power purchase contracts and the
termination or amendment of all related third party agreements), the IPPs
entering into new third party arrangements which will enable each IPP to
restructure its projects on a reasonably satisfactory economic basis, NIMO
having completed all necessary financing arrangements and NIMO and the IPPs
having received all necessary approvals from their respective boards of
directors, shareholders and partners.
 
    Discussions between the Company and its IPP counterparties have commenced.
Any proceeds received in consideration of termination of a Fixed-Price Contract
would be used to repay indebtedness outstanding under the Bank Credit Facility
and would be reflected in the Company's balance sheet as deferred hedging gains
to be amortized into oil and gas revenues over the original life of the
underlying contracts. However, the amount of any proceeds to be received by the
Company is subject to negotiation with the Company's counterparties and
contingent upon the counterparties participating in the closing of the MRA. At
this time, the Company cannot predict whether the conditions precedent to the
closing of the MRA will ultimately be satisfied. Negotiations with the Company's
counterparties are governed by confidentiality agreements. Cancellation of the
contracts would subject a greater portion of the Company's oil and gas
production to market prices, which in a low oil and gas price environment could
adversely affect the carrying value of the Company's oil and gas properties and
could otherwise have an adverse effect on the Company.

                         DESCRIPTION OF EXCHANGE NOTES
 
SUMMARY DESCRIPTION OF THE EXCHANGE NOTES
 
    The Existing Notes are and the Exchange Notes will be issued under an
Indenture, dated as of December 11, 1997 (the "Indenture"), between the Company
and LaSalle National Bank, as Trustee (the "Trustee"). The terms of the Exchange
Notes and the Existing Notes are identical in all material respects, except for
certain transfer restrictions relating to the Existing Notes. The Exchange Notes
will bear interest from the most recent date to which interest has been paid on
the Existing Notes or, if no interest has been paid on the Existing Notes, from
December 11, 1997. Accordingly, registered holders of Exchange Notes on the
relevant record date for the first interest payment date following the
consummation of the Exchange Offer will receive interest accruing from the most
recent date to which interest has been paid on the Existing Notes or, if no
interest has been paid, from December 11, 1997. Existing Notes accepted for
exchange will cease to accrue interest from and after the date of consummation
of the Exchange Offer. Holders whose Existing Notes are accepted for exchange
will not receive any payment in respect of interest on such Existing Notes
otherwise payable on any interest payment date the record date for which occurs
on or after consummation of the Exchange Offer.
 
TERMS OF THE EXCHANGE NOTES
 
    The Exchange Notes will be unsecured senior obligations of the Company,
limited to $200 million aggregate principal amount, and will mature on December
1, 2007. The Exchange Notes will bear interest at the rate per annum shown on
the cover page hereof from December 11, 1997, or from the most recent date to
which interest has been paid or provided for, payable semiannually to Holders of
record at the close of business on the May 15 or November 15 immediately
preceding the interest payment date on June 1 and December 1 of each year,
commencing June 1, 1998. The Company will pay interest on overdue principal at
1% per annum in excess of such rate, and it will pay interest on overdue
installments of interest at such higher rate to the extent lawful. Interest will
be paid on a 360-day year, twelve 30-day month basis.
 
    The interest rate on the Exchange Notes is subject to increase in certain
circumstances if the Company does not file a registration statement relating to
the Exchange Offer or if the registration statement is not declared effective on
a timely basis or if certain other conditions are not satisfied, all as further
described under "The Exchange Offer; Registration Rights."
 
OPTIONAL REDEMPTION
 
    The Exchange Notes will be redeemable at any time, at the option of the
Company, in whole or from time to time in part, upon not less than 30 and not
more than 60 days' notice as provided in the Indenture, on any date prior to
maturity (the "Redemption Date") at a price equal to 100% of the principal
amount thereof plus accrued interest to the Redemption Date (subject to the
right of Holders of record on the relevant record date to receive interest due
on an interest payment date that is on or prior to the Redemption Date) plus a
Make-Whole Premium, if any (the "Redemption Price"). In no event will the
Redemption Price ever be less than 100% of the principal amount of the Exchange
Notes plus accrued interest to the Redemption Date.
 
    The amount of the Make-Whole Premium with respect to any Exchange Note (or
portion thereof) to be redeemed will be equal to the excess, if any, of:
 
        (i) the sum of the present values, calculated as of the Redemption Date,
    of:
 
           (A) each interest payment that, but for such redemption, would have
       been payable on the Exchange Note (or portion thereof) being redeemed on
       each interest payment date occurring after the Redemption Date (excluding
       any accrued interest for the period prior to the Redemption Date); and
 
                                       26
<PAGE>
           (B) the principal amount that, but for such redemption, would have
       been payable at the final maturity of the Exchange Note (or portion
       thereof) being redeemed; over
 
        (ii) the principal amount of the Exchange Note (or portion thereof)
    being redeemed.
 
    The present values of interest and principal payments referred to in clause
(i) above will be determined in accordance with generally accepted principles of
financial analysis. Such present values will be calculated by discounting the
amount of each payment of interest or principal from the date that each such
payment would have been payable, but for the redemption, to the Redemption Date
at a discount rate equal to the Treasury Yield (as defined below) plus 20 basis
points.
 
    The Make-Whole Premium will be calculated by an independent investment
banking institution of national standing appointed by the Company; PROVIDED that
if the Company fails to make such appointment at least 45 business days prior to
the Redemption Date, or if the institution so appointed is unwilling or unable
to make such calculation, such calculation will be made by Salomon Brothers Inc
or, if such firm is unwilling or unable to make such calculation, by an
independent investment banking institution of national standing appointed by the
Trustee (in any such case, an "Independent Investment Banker").
 
    For purposes of determining the Make-Whole Premium, "Treasury Yield" means a
rate of interest per annum equal to the weekly average yield to maturity of
United States Treasury Notes that have a constant maturity that corresponds to
the remaining term to maturity of the Exchange Notes, calculated to the nearest
1/12th of a year (the "Remaining Term"). The Treasury Yield will be determined
as of the third business day immediately preceding the applicable Redemption
Date.
 
    The weekly average yields of United States Treasury Notes will be determined
by reference to the most recent statistical release published by the Federal
Reserve Bank of New York and designated "H.15(519) Selected Interest Rates" or
any successor release (the "H.15 Statistical Release"). If the H.15 Statistical
Release sets forth a weekly average yield for United States Treasury Notes
having a constant maturity that is the same as the Remaining Term, then the
Treasury Yield will be equal to such weekly average yield. In all other cases,
the Treasury Yield will be calculated by interpolation, on a straight-line
basis, between the weekly average yields on the United States Treasury Notes
that have a constant maturity closest to and greater than the Remaining Term and
the United States Treasury Notes that have a constant maturity closest to and
less than the Remaining Term (in each case as set forth in the H.15 Statistical
Release). Any weekly average yields so calculated by interpolation will be
rounded to the nearest 1/100th of 1%, with any figure of 1/200th of 1% or above
being rounded upward. If weekly average yields for United States Treasury Notes
are not available in the H.15 Statistical Release or otherwise, then the
Treasury Yield will be calculated by interpolation of comparable rates selected
by the Independent Investment Banker.
 
    In the case of any partial redemption, selection of the Notes for redemption
will be made by the Trustee on a pro rata basis, by lot or by such other method
as the Trustee in its sole discretion shall deem to be fair and appropriate,
although no Note of $1,000 in original principal amount or less shall be
redeemed in part. If any Note is to be redeemed in part only, the notice of
redemption relating to such Note shall state the portion of the principal amount
thereof to be redeemed. A new Note in principal amount equal to the unredeemed
portion thereof will be issued in the name of the Holder thereof upon
cancellation of the original Note.
 
RANKING
 
    The indebtedness evidenced by the Existing Notes is and the indebtedness
evidenced by the Exchange Notes will be senior unsecured obligations of the
Company, will rank PARI PASSU in right of payment with all existing and future
senior indebtedness of the Company and will be senior in right of payments to
all existing and future subordinated indebtedness of the Company. As of December
31, 1997, the Company
 
                                       27
<PAGE>
had $261 million principal amount of borrowings outstanding under the Bank
Credit Facility, with which the Notes would rank PARI PASSU.
 
BOOK-ENTRY, DELIVERY AND FORM
 
    Except as described below, the Notes will initially be issued in the form of
one or more Global Notes. The Global Notes will be deposited with, or on behalf
of, the Depository and registered in the name of the Depository or its nominee.
Except as set forth below, the Global Notes may be transferred, in whole and not
in part, only to the Depository or another nominee of the Depository. Investors
may hold their beneficial interests in the Global Notes directly through the
Depository if they have an account with the Depository or indirectly through
organizations which have accounts with the Depository.
 
    Upon the transfer of a Note in definitive form, such Note will, unless the
Global Notes have previously been exchanged for Notes in definitive form, be
exchanged for an interest in the Global Notes representing the principal amount
of Notes being transferred, with certain exceptions for transfers pursuant to
Rule 144.
 
    Notes originally purchased by persons outside the United States pursuant to
sales in accordance with Regulation S under the Securities Act will be
represented upon issuance by a temporary global Note certificate in fully
registered form without interest coupons (the "Temporary Certificate") which
will not be exchangeable for certificated Notes until the expiration of the
"40-day restricted period" within the meaning of Rule 903(c)(3) of Regulation S
under the Securities Act. The Temporary Note will be registered in the name of,
and held by, a temporary certificate holder until the expiration of such 40-day
period, at which time the Temporary Certificate will be delivered to the Trustee
in exchange for certificated Notes registered in the names requested by such
temporary certificate holder.
 
    The Depository has advised the Company as follows: The Depository is a
limited-purpose trust company organized under the laws of the State of New York,
a member of the Federal Reserve System, a "clearing corporation" within the
meaning of the New York Uniform Commercial Code, and "a clearing agency"
registered pursuant to the provisions of Section 17A of the Exchange Act. The
Depository was created to hold securities of institutions that have accounts
with the Depository ("participants") and to facilitate the clearance and
settlement of securities transactions among its participants in such securities
through electronic book-entry changes in accounts of the participants, thereby
eliminating the need for physical movement of securities certificates. The
Depository's participants include securities brokers and dealers (which may
include the Initial Purchasers), banks, trust companies, clearing corporations
and certain other organizations. Access to the Depository's book-entry system is
also available to others such as banks, brokers, dealers and trust companies
that clear through or maintain a custodial relationship with a participant,
whether directly or indirectly (collectively, the "indirect participants").
Holders who are not participants may beneficially own securities held by or on
behalf of the Depository only through participants or indirect participants.
 
    Upon the issuance of the Global Notes, the Depository will credit, on its
book-entry registration and transfer system, the principal amount of the Notes
represented by such Global Notes to the accounts of participants. The accounts
to be credited shall be designated by the Initial Purchasers of such Notes.
Ownership of beneficial interests in the Global Notes will be limited to
participants or persons that may hold interests through participants. Any person
acquiring an interest in a Global Note through an offshore transaction in
reliance on Regulation S may hold such interest through CEDEL or Euroclear.
Ownership of beneficial interests in the Global Notes will be shown on, and the
transfer of those ownership interests will be effected only through, records
maintained by the Depository (with respect to participants' interest) and such
participants (with respect to the owners of beneficial interests in the Global
Notes other than participants). The laws of some jurisdictions may require that
certain purchasers of securities take physical delivery of such securities in
definitive form. Such limits and laws may impair the ability to transfer or
pledge beneficial interests in the Global Notes.
 
                                       28
<PAGE>
    So long as the Depository, or its nominee, is the registered holder and
owner of the Global Notes, the Depository or such nominee, as the case may be,
will be considered the sole legal owner and holder of the related Notes for all
purposes of such Notes and the Indenture. Except as set forth below, owners of
beneficial interests in the Global Notes will not be entitled to have the Notes
represented by the Global Notes registered in their names, will not receive or
be entitled to receive physical delivery of certificated Notes in definitive
form and will not be considered to be the owners or holders of any Notes under
the Global Notes. The Company understands that under existing industry practice,
in the event an owner of a beneficial interest in the Global Notes desires to
take any action that the Depository, as the holder of the Global Notes, is
entitled to take, the Depository would authorize the participants to take such
action, and that the participants would authorize beneficial owners owning
through such participants to take such action or would otherwise act upon the
instructions of beneficial owners owning through them.
 
    Payment of principal and interest on Notes represented by the Global Notes
registered in the name of and held by the Depository or its nominee will be made
to the Depository or its nominee, as the case may be, as the registered owner
and holder of the Global Notes.
 
    The Company expects that the Depository or its nominee, upon receipt of any
payment of principal of or interest on the Global Notes, will credit
participants' accounts with payments in amounts proportionate to their
respective beneficial interests in the principal amount of the Global Notes as
shown on the records of the Depository or its nominee. The Company also expects
that payments by participants to owners of beneficial interests in the Global
Notes held through such participants will be governed by standing instructions
and customary practices and will be the responsibility of such participants. The
Company will not have any responsibility or liability for any aspect of the
records relating to, or payments made on account of, beneficial ownership
interests in the Global Notes for any Note or for maintaining, supervising or
reviewing any records relating to such beneficial ownership interests or for any
other aspect of the relationship between the Depository and its participants or
the relationship between such participants and the owners of beneficial
interests in the Global Notes owning through such participants.
 
    Unless and until it is exchanged in whole or in part for certificated Notes
in definitive form, the Global Notes may not be transferred except as a whole by
the Depository to a nominee of such Depository or by a nominee of such
Depository to such Depository or another nominee of such Depository.
 
    Although the Depository has agreed to the foregoing procedures in order to
facilitate transfers of interests in the Global Notes among participants of the
Depository, it is under no obligation to perform or continue to perform such
procedures, and such procedures may be discontinued at any time. Neither the
Trustee nor the Company will have any responsibility for the performance by the
Depository or its participants or indirect participants of their respective
obligations under the rules and procedures governing their operations.
 
CERTIFICATED NOTES
 
    The Notes represented by the Global Notes are exchangeable for certificated
Notes in definitive form of like tenor as such Notes in denominations of U.S.
$1,000 and integral multiples thereof if (i) the Depository notifies the Company
that it is unwilling or unable to continue as Depository for the Global Notes or
if at any time the Depository ceases to be a clearing agency registered under
the Exchange Act and a successor Depository is not appointed by the Company
within 90 days, (ii) the Company in its discretion at any time determines not to
have all of the Notes represented by the Global Notes, (iii) an Event of Default
has occurred and is continuing or (iv) upon the occurrence of certain other
events. Any Note that is exchangeable pursuant to the preceding sentence is
exchangeable for certificated Notes issuable in authorized denominations and
registered in such names as the Depository shall direct. Subject to the
foregoing, the Global Notes are not exchangeable, except for a Global Note of
the same aggregate denomination to be registered in the name of the Depository
or its nominee.

SAME-DAY PAYMENT
 
    The Indenture requires that payments in respect of Notes (including
principal, premium and interest) be made by wire transfer of immediately
available funds to the accounts specified by the Holders thereof or, if no such
account is specified, by mailing a check to each such Holder's registered
address.
 
CERTAIN COVENANTS
 
    The Indenture does not limit the amount of indebtedness or other obligations
that may be incurred by the Company and its subsidiaries and does not contain
provisions which would give holders of the Notes the right to require the
Company to repurchase their Notes in the event of a decline in the credit rating
of the Company's debt securities. The Indenture contains covenants including,
among others, the following:
 
    LIMITATION ON LIENS.  The Indenture provides that the Company will not, and
will not permit any of its Subsidiaries to, create, incur or otherwise cause or
suffer to exist or become effective any Liens of any kind upon any Principal
Property or any shares of stock or Indebtedness of any Subsidiary that owns or
leases any Principal Property (whether such Principal Property, shares of stock
or Indebtedness are now owned or hereafter acquired) unless all payments due
under the Indenture and the Notes are secured on an equal and ratable basis with
the obligations so secured until such time as such obligation is no longer
secured by a Lien, except for Permitted Liens. See also "Exempted Indebtedness"
below.
 
    LIMITATION ON SALE AND LEASEBACK TRANSACTIONS.  The Indenture provides that
neither the Company nor any Subsidiary will enter into any Sale and Leaseback
Transaction with respect to any Principal Property unless either (a) the Company
or such Subsidiary would be entitled, pursuant to the provisions of the
Indenture, to incur Indebtedness secured by a Lien on the property to be leased
without equally and ratably securing the Notes or (b) the Company, within 180
days after the effective date of such transaction, applies to the voluntary
retirement of its funded debt an amount equal to the value of such transaction,
defined as the greater of the net proceeds of the sale of the property leased in
such transaction or the fair value, in the opinion of the Board of Directors, of
the leased property at the time such transaction was entered into. See also
"Exempted Indebtedness" below.
 
    EXEMPTED INDEBTEDNESS.  Notwithstanding the foregoing limitations on Liens
and Sale and Leaseback Transactions, the Company and its Subsidiaries may issue,
assume, or guarantee Indebtedness secured by a Lien without securing the Notes,
or may enter into Sale and Leaseback Transactions without retiring funded debt,
or enter into a combination of such transactions, if the sum of the principal
amount of all such Indebtedness and the aggregate value of all such Sale and
Leaseback Transactions does not at any time exceed 15% of the Adjusted
Consolidated Net Tangible Assets of the Company.
 
    MERGER AND CONSOLIDATION.  The Indenture provides that the Company, without
the consent of the Holders of any of the outstanding Notes, may consolidate with
or merge into any other Person or convey, transfer or lease its properties and
assets substantially as an entirety to any Person or may permit any Person to
consolidate with or merge into, or transfer or lease its properties
substantially as an entirety to, the Company; PROVIDED that (a) the successor,
transferee or lessee is organized under the laws of any United States
jurisdiction; (b) the successor, transferee or lessee, if other than the
Company, expressly assumes the Company's obligations under the Indenture and the
Notes by means of a supplemental indenture entered into with the Trustee; (c)
after giving effect to the transaction, no Default shall have occurred and be
continuing; and (d) certain other conditions are met.
 
    Under any consolidation by the Company with, or merger by the Company into,
any other Person or any conveyance, transfer or lease of the properties and
assets of the Company substantially as an entirety as described in the preceding
paragraph, the successor resulting from such consolidation or into which the
Company is merged or the transferee or lessee to which such conveyance, transfer
or lease is made, will succeed to, and be substituted for, and may exercise
every right and power of, the Company under the
 
                                       30
<PAGE>
Indenture, and thereafter, except in the case of a lease, the predecessor (if
still in existence) will be released from its obligations and covenants under
the Indenture and the Notes.
 
EVENTS OF DEFAULT
 
    An Event of Default is defined in the Indenture to be a (i) default in the
payment of any interest upon any of the Notes for 30 days or more after such
payment is due, (ii) default in the payment of the principal of and premium, if
any, on any of the Notes when due, (iii) default by the Company in the
performance of any of its other covenants in the Indenture which will not have
been remedied by the end of a period of 60 days after written notice to the
Company by the Trustee or to the Company and the Trustee by the Holders of at
least 25% in principal amount of the outstanding Notes, and (iv) certain events
of bankruptcy, insolvency or reorganization of the Company or a Significant
Subsidiary.
 
    The Indenture provides that if an Event of Default (other than of a type
referred to in clause (iv) of the preceding paragraph) shall have occurred and
is continuing, either the Trustee or the Holders of at least 25% in principal
amount of the outstanding Notes may declare the principal amount of all Notes to
be immediately due and payable. Such declaration may be rescinded if certain
conditions are satisfied. If an Event of Default of the type referred to in
clause (iv) of the preceding paragraph shall have occurred, the principal amount
of the outstanding Notes shall automatically become immediately due and payable.
 
    The Indenture also provides that the Holders of not less than a majority in
principal amount of the outstanding Notes may direct the time, method and place
of conducting any proceedings for any remedy available to the Trustee, or
exercising any trust or power conferred on the Trustee; PROVIDED that such
direction is not in conflict with any rule of law or with the Indenture. The
Trustee may take any other action deemed proper by the Trustee which is not
inconsistent with such direction.
 
    The Indenture contains provisions entitling the Trustee, subject to the duty
of the Trustee during the continuance of an Event of Default to act with the
required standard of care, to be indemnified by the Holders of Notes before
proceeding to exercise any right or power under the Indenture at the request of
the Holders of Notes.
 
    No Holder of any Note will have any right to institute any proceeding with
respect to the Indenture or for any remedy thereunder, unless such Holder shall
have previously given to the Trustee written notice of a continuing Event of
Default and unless also the Holders of at least 25% in aggregate principal
amount of the outstanding Notes shall have made written request, and offered
reasonable indemnity, to the Trustee to institute such proceeding as Trustee,
and the Trustee shall not have received from the Holders of a majority in
aggregate principal amount of the outstanding Notes a direction inconsistent
with such request and shall have failed to institute such proceeding within 60
days. However, such limitations do not apply to a suit instituted by a Holder of
a Note for enforcement of payment of the principal of and premium, if any, or
interest on such Note on or after the respective due dates expressed in such
Note.
 
    The Indenture requires the Company to file annually with the Trustee a
certificate, executed by a designated officer of the Company, stating to the
best of his knowledge that the Company is not in default under certain covenants
under the Indenture or if he has knowledge that the Company is in such default,
specifying such default.
 
AMENDMENTS AND WAIVERS
 
    Subject to certain exceptions, the Indenture may be amended with the consent
of the Holders of a majority in principal amount of the Notes then outstanding
(including consents obtained in connection with a tender offer or exchange for
the Notes) and any past default or compliance with any provisions may also be
waived with the consent of the Holders of a majority in principal amount of the
Notes then outstanding. However, without the consent of each Holder of an
outstanding Note affected thereby, no amendment may, among other things, (i)
reduce the amount of Notes whose Holders must consent to an
 
                                       31
<PAGE>
amendment, (ii) reduce the rate of or extend the time for payment of interest on
any Note, (iii) reduce the principal of or extend the Stated Maturity of any
Note, (iv) reduce the amount payable upon the redemption of any Note or change
the time at which any Note may be redeemed as described under "--Optional
Redemption" above, (v) make any Note payable in money other than that stated in
the Note, (vi) impair the right of any Holder of the Notes to receive payment of
principal of and interest on such Holder's Notes on or after the due dates
therefor or to institute suit for the enforcement of any payment on or with
respect to such Holder's Notes or (vii) make any change in the amendment
provisions which require each Holder's consent or in the waiver provisions.
 
    Without the consent of any Holder of the Notes, the Company and Trustee may
amend the Indenture to cure any ambiguity, omission, defect or inconsistency, to
provide for the assumption by a successor corporation of the obligations of the
Company under the Indenture, to provide for uncertificated Notes in addition to
or in place of certificated Notes (PROVIDED that the uncertificated Notes are
issued in registered form for purposes of Section 163(f) of the Code, or in a
manner such that the uncertificated Notes are described in Section 163(f)(2)(B)
of the Code), to add guarantees with respect to the Notes, to secure the Notes,
to add to the covenants of the Company for the benefit of the Holders of the
Notes or to surrender any right or power conferred upon the Company, to make any
change that does not adversely affect the rights of any Holder of the Notes or
to comply with any requirement of the SEC in connection with the qualification
of the Indenture under the Trust Indenture Act of 1939, as amended.
 
    The consent of the Holders of the Notes is not necessary under the Indenture
to approve the particular form of any proposed amendment. It is sufficient if
such consent approves the substance of the proposed amendment.
 
    After an amendment under the Indenture becomes effective, the Company is
required to mail to Holders of the Notes a notice briefly describing such
amendment. However, the failure to give such notice to all Holders of the Notes,
or any defect therein, will not impair or affect the validity of the amendment.
 
TRANSFER
 
    The Notes will be issued in registered form and will be transferable only
upon the surrender of the Notes being transferred for registration of transfer.
The Company may require payment of a sum sufficient to cover any tax, assessment
or other governmental charge payable in connection with certain transfers and
exchanges.
 
DEFEASANCE
 
    The Company at any time may terminate all its obligations under the Notes
and the Indenture ("legal defeasance"), except for certain obligations,
including those respecting the defeasance trust and obligations to register the
transfer or exchange of the Notes, to replace mutilated, destroyed, lost or
stolen Notes and to maintain a registrar and paying agent in respect of the
Notes. The Company at any time may terminate its obligations under the covenants
described under "--Certain Covenants" (other than the covenant described under
"--Certain Covenants Merger and Consolidation"), and the bankruptcy provisions
with respect to Significant Subsidiaries described under "--Events of Default"
above and the limitations contained in clauses (c) and (d) under "--Certain
Covenants--Merger and Consolidation" above ("covenant defeasance").
 
    The Company may exercise its legal defeasance option notwithstanding its
prior exercise of its covenant defeasance option. If the Company exercises its
legal defeasance option, payment of the Notes may not be accelerated because of
an Event of Default with respect thereto. If the Company exercises its covenant
defeasance option, payment of the Notes may not be accelerated because of an
Event of Default specified in clause (iii) or (iv) under "--Events of Default"
above or because of the failure of the Company to comply with clause (c) or (d)
under "--Certain Covenants--Merger and Consolidation" above.
 
                                       32
<PAGE>
    In order to exercise either defeasance option, the Company must irrevocably
deposit in trust (the "defeasance trust") with the Trustee money or U.S.
Government Obligations for the payment of principal and interest on the Notes to
redemption or maturity, as the case may be, and must comply with certain other
conditions, including delivery to the Trustee of an Opinion of Counsel to the
effect that Holders of the Notes will not recognize income, gain or loss for
U.S. federal income tax purposes as a result of such deposit and defeasance and
will be subject to U.S. federal income tax on the same amounts and in the same
manner and at the same times as would have been the case if such deposit and
defeasance had not occurred (and, in the case of legal defeasance only, such
Opinion of Counsel must be based on a ruling of the Internal Revenue Service or
other change in applicable U.S. federal income tax law).
 
CONCERNING THE TRUSTEE
 
    LaSalle National Bank is the Trustee under the Indenture and has been
appointed by the Company as Registrar and Paying Agent with regard to the Notes.
 
    The Holders of a majority in principal amount of the outstanding Notes will
have the right to direct the time, method and place of conducting any proceeding
for exercising any remedy available to the Trustee, subject to certain
exceptions. The Indenture provides that if an Event of Default occurs (and is
not cured), the Trustee will be required, in the exercise of its power, to use
the degree of care of a prudent man in the conduct of his own affairs. Subject
to such provisions, the Trustee will be under no obligation to exercise any of
its rights or powers under the Indenture at the request of any Holder of Notes,
unless such Holder shall have offered to the Trustee security and indemnity
satisfactory to it against any loss, liability or expense and then only to the
extent required by the terms of the Indenture.
 
GOVERNING LAW
 
    The Indenture provides that it and the Notes will be governed by, and
construed in accordance with, the laws of the State of New York without giving
effect to applicable principles of conflicts of law to the extent that the
application of the law of another jurisdiction would be required thereby.

    future net revenues from (A) estimated proved oil and gas reserves acquired
    since such year-end, which reserves were not reflected in such year-end
    reserve report, and (B) estimated oil and gas reserves attributable to
    upward revisions of estimates of proved oil and gas reserves since such
    year-end due to exploration, development or exploitation activities, in each
    case calculated in accordance with SEC guidelines (utilizing the prices

    of determination, the estimated discounted future net revenues from (C)
    estimated proved oil and gas reserves produced or disposed of since such

    revisions of estimates of proved oil and gas reserves since such year-end
    due to changes in geological conditions or other factors which would, in
    accordance with standard industry practice, cause such revisions, in each
    case calculated in accordance with SEC guidelines (utilizing the
 
                                       33
<PAGE>

    confirmed in writing by a nationally recognized firm of independent
    petroleum engineers, (ii) the capitalized costs that are attributable to oil
    and gas properties of the Company and its Subsidiaries to which no proved

    Production Payments (determined, if applicable, using the schedules
    specified with respect thereto) and (iv) the discounted future net revenues,
    calculated in accordance with SEC guidelines, attributable to reserves
    subject to Dollar-Denominated Production Payments which, based on the
    estimates of production and price assumptions included in determining the
    discounted future net revenues specified in (a)(i) above, would be necessary
    to fully satisfy the payment obligations of the Company and its Subsidiaries
    with respect to Dollar-Denominated Production Payments (determined, if
    applicable, using the schedules specified with respect thereto). If the
    Company changes its method of accounting from the successful efforts method

                               THE EXCHANGE OFFER
 
PURPOSE AND EFFECT OF THE EXCHANGE OFFER
 
    The Existing Notes were originally sold by the Company on December 11, 1997,
to the Initial Purchasers pursuant to the Purchase Agreement. The Initial
Purchasers subsequently resold the Existing Notes to qualified institutional
buyers pursuant to Rule 144A under the Securities Act, or outside the United
States in compliance with Regulation S under the Securities Act. Pursuant to the
Purchase Agreement the Company entered into a registration rights agreement with
the Initial Purchasers (the "Registration Agreement") pursuant to which the
Company agreed, for the benefit of the holders of the Existing Notes, at the
Company's cost, to (i) file a registration statement (the "Exchange Offer
Registration Statement") within 150 days after the date of original issuance of
such Existing Notes (the "Issue Date") with the Commission with respect to
registered offers to exchange each of such Existing Notes for debentures (the
"Exchange Notes") with terms identical in all material respects thereto (except
that the Exchange Notes will not contain terms with respect to transfer
restrictions or the special interest payments described below), and (ii) use its
best efforts to cause the Exchange Offer Registration Statement to be declared
effective under the Securities Act within 180 days after the Issue Date.
Promptly after the Exchange Offer Registration Statement is declared effective,
the Company will offer the Exchange Notes in exchange for surrender of the
Existing Notes (the "Exchange Offer"). The Company will keep the Exchange Offer
open for not less than 30 days (or longer if required by applicable law) after
the date notice of the Exchange Offer is mailed to the holders of the Existing
Notes.
 
    For each Existing Note properly tendered and accepted pursuant to the
Exchange Offer and not withdrawn by the holder thereof, the holder of such
Existing Note will receive an Exchange Note having a principal amount equal to
that of the Existing Note tendered. Interest on each Exchange Note will accrue
from the last respective interest date on which interest was paid on the
Existing Note tendered in exchange therefor or, if no interest has been paid on
such Existing Note, from the Issue Date.
 
    Based on existing interpretations of the Securities Act by the staff of the
Commission set forth in several no-action letters to third parties with respect
to similar transactions, including "Exxon Capital Holdings Corporation"
(available May 13, 1988) and "Morgan Stanley & Co. Incorporated" (available June
5, 1991) and similar no-action letters, and subject to the immediately following
sentence, the Company believes that the Exchange Notes issued pursuant to the
Exchange Offer may be offered for resale, resold and otherwise transferred by
the holders thereof (other than holders who are broker-dealers) without further
compliance with the registration and prospectus delivery provisions of the
Securities Act. As the Company has not sought a no-action letter with respect to
the Exchange Offer, there can be no assurance that the Staff of the Commission
would make a similar determination with respect to the Exchange Offer. However,
any holder of Existing Notes who is an "affiliate" of the Company or who intends
to participate in the Exchange Offer for the purpose of distributing the
Exchange Notes, or any Initial Purchasers (i) will not be able to rely on the
interpretation by the staff of the Commission set forth in the above-mentioned
no-action letters, (ii) will not be able to tender its Existing Notes in the
Exchange Offer and (iii) must comply with the registration and prospectus
delivery requirements of the Securities Act in connection with any sale or
transfer of the Exchange Notes unless such sale or transfer is made pursuant to
an exemption from such requirements.
 
    Each holder of the Existing Notes (other than certain specified holders) who
wishes to exchange Existing Notes for Exchange Notes in the Exchange Offer will
be required to represent in the Letter of Transmittal that among other things
(i) it is not an affiliate of the Company, (ii) any Exchange Notes to be
received by it were acquired in the ordinary course of its business and (iii) at
the time of commencement of the Exchange Offer, it has no arrangement with any
person to participate in the distribution (within the meaning of the Securities
Act) of the Exchange Notes. In addition, in connection with any resales of
Exchange Notes, any broker-dealer (an "Exchanging Dealer") who acquired the
Existing Notes for its own account as a result of market-making activities or
other trading activities must deliver a prospectus meeting
 
                                       39
<PAGE>
the requirements of the Securities Act. The Commission has taken the position
that Exchanging Dealers may fulfill their prospectus delivery requirements with
respect to the Exchange Notes (other than a resale of an unsold allotment from
the original sale of the Notes) with the prospectus contained in the Exchange
Offer Registration Statement. Under the Registration Agreement, the Company is
required to allow Exchanging Dealers and other persons, if any, subject to
similar prospectus delivery requirements to use the prospectus contained in the
Exchange Offer Registration Statement in connection with the resale of such
Exchange Notes for a period of 180 days (exclusive of any period during which a
stop order shall be in effect suspending the effectiveness of the Registration
Statement) after the consummation of the Exchange Offer.
 
    In the event that any changes in law or applicable interpretations of the
staff of the Commission do not permit the Company to effect the Exchange Offer
with respect to the Notes, or if for any reason the Exchange Offer Registration
Statement is not declared effective within 180 days following the Issue Date, or
upon the request of the Initial Purchasers under certain circumstances, the
Company will, in lieu of effecting the registration of the applicable Exchange
Notes pursuant to the Exchange Offer Registration Statement and at its cost, (i)
as promptly as practicable, file with the Commission a Shelf Registration
Statement (the "Shelf Registration Statement") covering resales of the Existing
Notes, (ii) use its best efforts to cause the Shelf Registration Statement to be
declared effective under the Securities Act by the 210th day after the Issue
Date (or promptly in the event of a request by the Initial Purchasers) and (iii)
keep effective the Shelf Registration Statement until the earliest of (x) the
second anniversary of the Issue Date (or the first anniversary of the effective
date if such Shelf Registration Statement is filed at the request of the Initial
Purchasers), (y) the time when the Existing Notes registered thereunder can be
sold by non-affiliates pursuant to Rule 144 under the Securities Act without
limitation under clauses (c), (e), (f) and (h) of Rule 144, or (z) such time as
all the Existing Notes registered thereunder have been sold. See "--Resale of
the Exchange Notes." During any consecutive 365-day period, the Company will
have the ability to suspend the availability of the Shelf Registration Statement
for up to two periods of up to 45 consecutive days, but no more than an
aggregate of 60 days during any 365-day period. The Company will, in the event
of the filing of a Shelf Registration Statement, provide to each holder of such
Existing Notes copies of the prospectus which is part of the Shelf Registration
Statement, notify each such holder when the Shelf Registration Statement for
such Existing Notes has become effective and take certain other actions as are
required to permit unrestricted resales of such Existing Notes. A holder of such
Notes that sells such Existing Notes pursuant to the Shelf Registration
Statement generally will be required to be named as a selling security holder in
the related prospectus and to deliver a prospectus to the purchaser, will be
subject to certain of the civil liability provisions under the Securities Act in
connection with such sales and will be bound by the provisions of the
Registration Agreement which are applicable to such a holder (including certain
indemnification obligations). In addition, each holder of such Existing Notes
will be required to deliver information to be used in connection with the Shelf
Registration Statement and to provide comments on the Shelf Registration
Statement within the time periods set forth in the Registration Agreement in
order to have their Existing Notes included in the Shelf Registration Statement
and to benefit from the provisions regarding Special Interest set forth in the
following paragraph. If the Company has consummated the Exchange Offer, then,
subject to certain limited exceptions, the Company will have no obligation to
file or to maintain the effectiveness of a Shelf Registration Statement with
respect to any Existing Notes that are not tendered in the Exchange Offer.
 
    In the event that (i) by the 150th day following the Issue Date, the
Exchange Offer Registration Statement is not filed with the Commission, (ii) by
the 180th day following the Issue Date, neither the Exchange Offer Registration
Statement is declared effective nor (if the Exchange Offer is not permitted as
described above) the Shelf Registration Statement is filed with the Commission,
or (iii) by the 210th day following the Issue Date, the Exchange Offer is not
consummated or the Shelf Registration Statement is not declared effective with
respect thereto (each such event referred to in clauses (i) through (iii), a
"Registration Default"), interest will accrue on the applicable Existing Notes
(in addition to stated interest on such Notes) which, except as provided below,
shall be the sole and exclusive remedy for such
 
                                       40
<PAGE>
Registration Default from and including the next day following each such
Registration Default. In each case such additional interest (the "Special
Interest") will be payable in cash semiannually in arrears each June1 and
December 1, at a rate per annum equal to 0.25% of the principal amount of such
Existing Notes for each such Registration Default. The aggregate amount of
Special Interest payable pursuant to the above provisions will in no event
exceed 0.25% per annum of the principal amount of such Existing Notes which,
except as provided below, shall be the sole and exclusive remedy for such
Registration Default. Upon (a) the filing of the Exchange Offer Registration
Statement after the 150-day period described in clause (i) above, (b) the
effectiveness of the Exchange Offer Registration Statement or the filing of the
Shelf Registration Statement after the 180-day period described in clause (ii)
above or (c) the consummation of the Exchange Offer for such Notes or the
effectiveness of a Shelf Registration Statement, as the case may be, after the
210-day period described in clause (iii) above, the Special Interest payable on
such Notes as a result of the applicable Registration Default will cease to
accrue. For purposes of the preceding sentence, the curing of a Registration
Default by the means described in clause (b) above shall constitute a cure of
the Registration Defaults described in clauses (i) and (ii) above, and the
curing of a Registration Default by the means described in clause (c) above
shall constitute a cure of the Registration Defaults described in clauses (i),
(ii) and (iii) above. The Company will have no other liabilities for monetary
damages with respect to the above; PROVIDED, HOWEVER, that in the event the
Company breaches, fails to comply with or violates certain provisions of the
Registration Agreement, the holders of Existing Notes shall be entitled to, and
the Company shall not oppose the granting of, equitable relief, including
injunction and specific performance.
 
    In the event that a Shelf Registration Statement is declared effective
pursuant to the paragraph preceding the immediately preceding paragraph, if the
Company fails to keep such Registration Statement continuously effective for the
period required by the Registration Agreement (except as specifically permitted
therein), then from such time as the Shelf Registration Statement is no longer
effective until the earlier of (i) the date that the Shelf Registration
Statement is again deemed effective and (ii) the date that is the earliest of
(x) the second anniversary of the Issue Date (or until the first anniversary of
the effective date if the Shelf Registration Statement is filed at the request
of the Initial Purchasers), (y) the time when the Existing Notes registered
thereunder can be sold by non-affiliates pursuant to Rule 144 under the
Securities Act without any limitation under clauses (c), (e), (f) and (h) of
Rule 144, or (z) the date as of which all such Existing Notes are sold pursuant
to the Shelf Registration Statement, Special Interest shall accrue at a rate per
annum equal to 0.25% of the principal amount of the Existing Notes which, except
as provided below, shall be the sole and exclusive remedy for such Registration
Default and shall be payable in cash semiannually in arrears each June 1 and
December 1. The Company will have no other liabilities for monetary damages with
respect to the above; PROVIDED, HOWEVER, that in the event the Company breaches,
fails to comply with or violates certain provisions of the Registration
Agreement, the holders of Existing Notes shall be entitled to, and the Company
shall not oppose the granting of, equitable relief, including injunction and
specific performance.
 
    The summary herein of certain provisions of the Registration Agreement does
not purport to be complete and is subject to, and is qualified in its entirety
by reference to, all the provisions of the Registration Agreement, a copy of
which is available upon request to the Company.
 
    Following the consummation of the Exchange Offer, holders of the Existing
Notes who were eligible to participate in the Exchange Offer but who did not
tender their Existing Notes will not have any further exchange or registration
rights and such Existing Notes will continue to be subject to certain
restrictions on transfer. Accordingly, the liquidity of the market for such
Existing Notes could be adversely affected.
 
TERMS OF THE EXCHANGE OFFER
 
    Upon the terms and subject to the conditions set forth in this Prospectus
and in the Letter of Transmittal, the Company will accept any and all Existing
Notes validly tendered and not withdrawn prior to 5:00 p.m., New York City time,
on the Expiration Date. The Company will issue $1,000 principal amount
 
                                       41
<PAGE>
of Exchange Notes in exchange for each $1,000 principal amount of outstanding
Existing Notes accepted in the Exchange Offer. Holders may tender some or all of
their Existing Notes pursuant to the Exchange Offer. However, Existing Notes may
be tendered only in integral multiples of $1,000.
 
    The form and terms of the Exchange Notes are the same as the form and terms
of the Existing Notes except (i) the Exchange Notes bear a different CUSIP
Number from the Existing Notes and (ii) the Exchange Notes have been registered
under the Securities Act and hence will not bear legends restricting the
transfer thereof. The Exchange Notes will evidence the same debt as the Existing
Notes and will be entitled to the benefits of the Indenture.
 
    As of the date of this Prospectus, $200,000,000 aggregate principal amount
of Existing Notes are outstanding. The Company has fixed the close of business
on            , 1998 as the record date for the Exchange Offer for purposes of
determining the persons to whom this Prospectus and the Letter of Transmittal
will be mailed initially.
 
    Holders of the Existing Notes do not have any appraisal or dissenters'
rights under the General Corporation Act of Oklahoma or the Indenture in
connection with the Exchange Offer. The Company intends to conduct the Exchange
Offer in accordance with the applicable requirements of the Exchange Act and the
rules and regulations of the Commission thereunder.
 
    The Company shall be deemed to have accepted validly tendered Existing Notes
when, as and if the Company has given oral or written notice thereof to the
Exchange Agent. The Exchange Agent will act as agent for the tendering holders
for the purpose of receiving the Exchange Notes from the Company.
 
    If any tendered Existing Notes are not accepted for exchange because of an
invalid tender, the occurrence of certain other events set forth herein or
otherwise, the certificates for any such unaccepted Existing Notes will be
returned, without expense, to the tendering holder thereof as promptly as
practicable after the Expiration Date.
 
    Holders who tender Existing Notes in the Exchange Offer will not be required
to pay brokerage commissions or fees or, subject to the instructions of the
Letter of Transmittal, transfer taxes with respect to the exchange of Existing
Notes pursuant to the Exchange Offer. The Company will pay all charges and
expenses, other than the transfer taxes in certain circumstances, in connection
with the Exchange Offer. See "--Fees and Expenses."
 
EXPIRATION DATE; EXTENSIONS; AMENDMENTS
 
    The term "Expiration Date" shall mean 5:00 p.m., New York City time, on
           , 1998 unless the Company, in its sole discretion, extends the
Exchange Offer, in which case the term "Expiration Date" shall mean the latest
date and time to which the Exchange Offer is extended.
 
    In order to extend the Exchange Offer, the Company will notify the Exchange
Agent of any extension by oral or written notice and will mail to the registered
holders an announcement thereof, each prior to 9:00 a.m., New York City time, on
the next business day after the previously scheduled expiration date.
 
    The Company reserves the right (i) to delay accepting any Existing Notes, to
extend the Exchange Offer or to terminate the Exchange Offer if any of the
conditions set forth below under "--Conditions" shall not have been satisfied,
by giving oral or written notice of such delay, extension or termination to the
Exchange Agent or (ii) to amend the terms of the Exchange Offer in any manner.
Any such delay in acceptance, extension, termination or amendment will be
followed as promptly as practicable by oral or written notice thereof to the
registered holders.
 
PROCEDURES FOR TENDERING
 
    The tender of Existing Notes pursuant to any of the procedures set forth in
this Prospectus and in the Letter of Transmittal will constitute a binding
agreement between the Tendering Holder and the Company
 
                                       42
<PAGE>
in accordance with the terms and subject to the conditions set forth herein and
in the Letter of Transmittal. The tender of Existing Notes will constitute an
agreement to deliver good and marketable title to all tendered Existing Notes
prior to the Expiration Date free and clear of all liens, charges, claims,
encumbrances, interests and restrictions of any kind.
 
    EXCEPT AS PROVIDED IN "--GUARANTEED DELIVERY PROCEDURES," UNLESS THE
EXISTING NOTES BEING TENDERED ARE DEPOSITED BY THE HOLDER WITH THE EXCHANGE
AGENT PRIOR TO THE EXPIRATION DATE (ACCOMPANIED BY A PROPERLY COMPLETED AND DULY
EXECUTED LETTER OF TRANSMITTAL), THE COMPANY MAY, AT ITS OPTION, REJECT SUCH
TENDER. ISSUANCE OF EXCHANGE NOTES WILL BE MADE ONLY AGAINST DEPOSIT OF TENDERED
EXISTING NOTES AND DELIVERY OF ALL OTHER REQUIRED DOCUMENTS. NOTWITHSTANDING THE
FOREGOING, DTC PARTICIPANTS TENDERING THROUGH ATOP WILL BE DEEMED TO HAVE MADE
VALID DELIVERY WHERE THE EXCHANGE AGENT RECEIVES AN AGENT'S MESSAGE (DEFINED
BELOW) PRIOR TO THE EXPIRATION DATE.
 
    Accordingly, to properly tender Existing Notes, the following procedures
must be followed:
 
    EXISTING NOTES HELD THROUGH DTC.  Each Beneficial Owner holding Existing
Notes through a DTC Participant must instruct such DTC Participant to cause its
Existing Notes to be tendered in accordance with the procedures set forth in
this Prospectus.
 
    Pursuant to an authorization given by DTC to the DTC Participants, each DTC
Participant holding Existing Notes through DTC must (i) electronically transmit
its acceptance through ATOP, and DTC will then edit and verify the acceptance,
execute a book-entry delivery to the Exchange Agent's account at DTC
and send an Agent's Message to the Exchange Agent for its acceptance, or (ii)
comply with the guaranteed delivery procedures set forth below and in the Notice
of Guaranteed Delivery. See "--Guaranteed Delivery Procedures."
 
    The Exchange Agent will (promptly after the date of this Prospectus)
establish accounts at DTC for purposes of the Exchange Offer with respect to
Existing Notes held through DTC, and any financial institution that is a DTC
Participant may make book-entry delivery of interests in Existing Notes into the
Exchange Agent's account through ATOP. However, although delivery of interests
in the Existing Notes may be effected through book-entry transfer into the
Exchange Agent's account through ATOP, an Agent's Message in connection with
such book-entry transfer, and any other required documents, must be, in any
case, transmitted to and received by the Exchange Agent at its address set forth
under "--Exchange Agent," or the guaranteed delivery procedures set forth below
must be complied with, in each case, prior to the Expiration Date. Delivery of
documents to DTC does not constitute delivery to the Exchange Agent. The
confirmation of a book-entry transfer into the Exchange Agent's account at DTC
as described above is referred to herein as a "Book-Entry Confirmation."
 
    The term "Agent's Message" means a message transmitted by DTC to, and
received by, the Exchange Agent and forming a part of the Book-Entry
Confirmation, which states that DTC has received an express acknowledgment from
each DTC Participant tendering through ATOP that such DTC Participants have
received a Letter of Transmittal and agree to be bound by the terms of the
Letter of Transmittal and that the Company may enforce such agreement against
such DTC Participants.
 
    Cede & Co., as the Holder of the global certificates representing the
Existing Notes (each a "Global Security," or together, the "Global Securities"),
will tender a portion of each of the Global Securities equal to the aggregate
principal amount due at the stated maturity for which instructions to tender are
given by DTC Participants.
 
    EXISTING NOTES HELD BY HOLDERS.  Each Holder must (i) complete and sign and
mail or deliver the accompanying Letter of Transmittal, and any other documents
required by the Letter of Transmittal, together with certificate(s) representing
all tendered Existing Notes, to the Exchange Agent at its address set forth
under "--Exchange Agent," or (ii) comply with the guaranteed delivery procedures
set forth below and in the Notice of Guaranteed Delivery. See "--Guaranteed
Delivery Procedures."
 
                                       43
<PAGE>
    All signatures on a Letter of Transmittal must be guaranteed by any member
firm of a registered national securities exchange or of the National Association
of Securities Dealers, Inc., a commercial bank or trust company having an office
or correspondent in the United States or an "eligible guarantor" institution
within the meaning of Rule 17Ad-15 under the Exchange Act (each an "Eligible
Institution"); PROVIDED, HOWEVER, that signatures on a Letter of Transmittal
need not be guaranteed if such Existing Notes are tendered for the account of an
Eligible Institution, including (as such terms are defined in Rule 17Ad-15): (i)
a bank; (ii) a broker, dealer, municipal securities dealer, municipal securities
broker, government securities dealer or government securities broker; (iii) a
credit union; (iv) a national securities exchange, registered securities
association or clearing agency; or (v) a savings institution that is a
participant in a Securities Transfer Association recognized program.
 
    If a Letter of Transmittal or any Existing Note is signed by a trustee,
executor, administrator, guardian, attorney-in-fact, agent, officer of a
corporation or other person acting in a fiduciary or representative capacity,
such person must so indicate when signing, and proper evidence satisfactory to
the Company of the authority of such person so to act must be submitted.
 
    Holders should indicate in the applicable box in the Letter of Transmittal
the name and address to which substitute certificates evidencing Existing Notes
for amounts not tendered are to be issued or sent, if different from the name
and address of the person signing the Letter of Transmittal. In the case of
issuance in a different name, the employer identification or social security
number of the person named must also be indicated. If no instructions are given,
such Existing Notes not tendered, as the case may be, will be returned to the
person signing the Letter of Transmittal.
 
    By tendering, each Holder and each DTC Participant will make to the Company
the representations set forth in the fourth paragraph under the heading
"--Purpose and Effect of the Exchange Offer."
 
    No alternative, conditional, irregular or contingent tenders will be
accepted (unless waived). By executing a Letter of Transmittal or transmitting
an acceptance through ATOP, as the case may be, each Tendering Holder waives any
right to receive any notice of the acceptance for purchase of its Existing
Notes.
 
    All questions as to the validity, form, eligibility (including time of
receipt) and acceptance of tendered Existing Notes will be resolved by the
Company, whose determination will be final and binding. The Company reserves the
absolute right to reject any or all tenders that are not in proper form or the
acceptance of which may, in the opinion of counsel for the Company, be unlawful.
The Company also reserves the absolute right to waive any condition to the
Exchange Offer and any irregularities or conditions of tender as to particular
Existing Notes. The Company's interpretation of the terms and conditions of the
Exchange Offer (including the instructions in the Letter of Transmittal) will be
final and binding. Unless waived, any irregularities in connection with tenders
must be cured within such time as the Company shall determine. The Company and
the Exchange Agent shall not be under any duty to give notification of defects
in such tenders and shall not incur liabilities for failure to give such
notification. Tenders of Existing Notes will not be deemed to have been made
until such irregularities have been cured or waived. Any Existing Notes received
by the Exchange Agent that are not properly tendered and as to which the
irregularities have not been cured or waived will be returned by the Exchange
Agent to the tendering Holder, unless otherwise provided in the Letter of
Transmittal, as soon as practicable following the Expiration Date.
 
    LETTERS OF TRANSMITTAL AND EXISTING NOTES MUST BE SENT ONLY TO THE EXCHANGE
AGENT. DO NOT SEND LETTERS OF TRANSMITTAL OR EXISTING NOTES TO THE COMPANY OR
DTC.
 
    The method of delivery of Existing Notes and Letters of Transmittal, any
required signature guaranties and all other required documents, including
delivery through DTC and any acceptance through ATOP, is at the election and
risk of the persons tendering and delivering acceptances or Letters of
Transmittal and, except as otherwise provided in the applicable Letter of
Transmittal, delivery will be deemed made
 
                                       44
<PAGE>
only when actually received by the Exchange Agent. If delivery is by mail, it is
suggested that the Holder use properly insured, registered mail with return
receipt requested, and that the mailing be made sufficiently in advance of the
Expiration Date to permit delivery to the Exchange Agent prior to the Expiration
Date.
 
GUARANTEED DELIVERY PROCEDURES
 
    EXISTING NOTES HELD THROUGH DTC.  DTC Participants holding Existing Notes
through DTC (the "Book-Entry Transfer Facility") who wish to cause their
Existing Notes to be tendered, but who cannot transmit their acceptances through
ATOP prior to the Expiration Date, may cause a tender to be effected if:
 
        (a) guaranteed delivery is made by or through an Eligible Institution;
 
        (b) prior to 5:00 p.m., New York City time on the Expiration Date, the
    Exchange Agent receives from such Eligible Institution a properly completed
    and duly executed Notice of Guaranteed Delivery (by mail, hand delivery,
    facsimile transmission or overnight courier) substantially in the form
    provided by the Company herewith; and
 
        (c) Book-Entry Confirmation and an Agent's Message in connection
    therewith (as described above) are received by the Exchange Agent within
    three New York Stock Exchange trading days after the date of the execution
    of the Notice of Guaranteed Delivery.
 
    EXISTING NOTES HELD BY HOLDERS.  Holders who wish to tender their Existing
Notes and (i) whose Existing Notes are not immediately available, (ii) who
cannot deliver their Existing Notes, the Letter of Transmittal or any other
required documents to the Exchange Agent or (iii) who cannot complete the
procedures for book-entry transfer, prior to the Expiration Date, may effect a
tender if:
 
        (a) the tender is made through an Eligible Institution;
 
        (b) prior to 5:00 p.m., New York City time on the Expiration Date, the
    Exchange Agent receives from such Eligible Institution a properly completed
    and duly executed Notice of Guaranteed Delivery (by facsimile transmission,
    mail or hand delivery) setting forth the name and address of the holder, the
    certificate number(s) of such Existing Notes and the principal amount of
    Existing Notes tendered, stating that the tender is being made thereby and
    guaranteeing that, within three New York Stock Exchange trading days after
    the Expiration Date, the Letter of Transmittal (or facsimile thereof)
    together with the certificate(s) representing the Existing Notes (or a
    confirmation of book-entry transfer of such Existing Notes into the Exchange
    Agent's account at the Book-Entry Transfer Facility), and any other
    documents required by the Letter of Transmittal will be deposited by the
    Eligible Institution with the Exchange Agent; and
 
        (c) such properly completed and executed Letter of Transmittal (or
    facsimile thereof), as well as the certificate(s) representing all tendered
    Existing Notes in proper form for transfer (or a confirmation or book-entry
    transfer of such Existing Notes into the Exchange Agent's account at the
    Book-Entry Transfer Facility), and all other documents required by the
    Letter of Transmittal are received by the Exchange Agent upon three New York
    Stock Exchange trading days after the Expiration Date.
 
    Upon request to the Exchange Agent, a Notice of Guaranteed Delivery will be
sent to holders who wish to tender their Existing Notes according to the
guaranteed delivery procedures set forth above.
 
WITHDRAWAL OF TENDERS
 
    Except as otherwise provided herein, tenders of Existing Notes may be
withdrawn at any time prior to 5:00 p.m., New York City time, on the Expiration
Date.
 
                                       45
<PAGE>
    EXISTING NOTES HELD THROUGH DTC.  DTC Participants holding Existing Notes
who have transmitted their acceptances through ATOP may, prior to 5:00 p.m., New
York City time, on the Expiration Date, withdraw the instruction given thereby
by delivering to the Exchange Agent, at its address set forth under "--Exchange
Agent," a written, telegraphic or facsimile notice of withdrawal of such
instruction. Such notice of withdrawal must contain the name and number of the
DTC Participant, the principal amount due at the stated maturity of the Existing
Notes to which such withdrawal relates and the signature of the DTC Participant.
Withdrawal of such an instruction will be effective upon receipt of such written
notice of withdrawal by the Exchange Agent.
 
    EXISTING NOTES HELD BY HOLDERS.  Holders may withdraw a tender of Existing
Notes in the Exchange Offer, by a telegram, telex, letter or facsimile
transmission notice of withdrawal received by the Exchange Agent at its address
set forth herein prior to 5:00 p.m., New York City time, on the Expiration Date.
Any such notice of withdrawal must (i) specify the name of the person having
deposited the Existing Notes to be withdrawn (the "Depositor"), (ii) identify
the Existing Notes to be withdrawn (including the certificate number(s) and
principal amount due at the stated maturity of such Existing Notes, or, in the
case of Existing Notes transferred by book-entry transfer, the name and number
of the account at the Book-Entry Transfer Facility to be credited), (iii) be
signed by the holder in the same manner as the original signature on the Letter
of Transmittal by which such Existing Notes were tendered (including any
required signature guarantees) or be accompanied by documents of transfer
sufficient to have the Trustee with respect to the Existing Notes register the
transfer of such Existing Notes into the name of the person withdrawing the
tender and (iv) specify the name in which any such Existing Notes are to be
registered, if different from that of the Depositor. All questions as to the
validity, form and eligibility (including time of receipt) of such notices will
be determined by the Company, whose determination shall be final and binding on
all parties. Any Existing Notes so withdrawn will be deemed not to have been
validly tendered for purposes of the Exchange Offer, and no Exchange Notes will
be issued with respect thereto unless the Existing Notes so withdrawn are
validly re-tendered. Any Existing Notes which have been tendered but which are
not accepted for exchange will be returned to the holder thereof without cost to
such holder as soon as practicable after withdrawal, rejection of tender or
termination of the Exchange Offer. Properly withdrawn Existing Notes may be
re-tendered by following one of the procedures described above under
"--Procedures for Tendering" at any time prior to the Expiration Date.
 
    All signatures on a notice of withdrawal must be guaranteed by an Eligible
Institution; PROVIDED, HOWEVER, that signatures on the notice of withdrawal need
not be guaranteed if the Existing Notes being withdrawn are held for the account
of an Eligible Institution.
 
    A withdrawal of an instruction or a withdrawal of a tender must be executed
by a DTC Participant or a Holder, as the case may be, in the same manner as the
person's name appears on its transmission through ATOP or Letter of Transmittal,
as the case may be, to which such withdrawal relates. If a notice of withdrawal
is signed by a trustee, partner, executor, administrator, guardian,
attorney-in-fact, agent, officer of a corporation or other person acting in a
fiduciary or representative capacity, such person must so indicate when signing
and must submit with the revocation appropriate evidence of authority to execute
the notice of withdrawal. A DTC Participant or a Holder may withdraw an
instruction or a tender, as the case may be, only if such withdrawal complies
with the provisions of this Prospectus.
 
    A withdrawal of a tender of Existing Notes by a DTC Participant or a Holder,
as the case may be, may be rescinded only by a new transmission of an acceptance
through ATOP or execution and delivery of a new Letter of Transmittal, as the
case may be, in accordance with the procedures described herein.
 
CONDITIONS
 
    Notwithstanding any other term of the Exchange Offer, and subject to its
obligations pursuant to the Registration Agreement, the Company shall not be
required to accept for exchange, or exchange securities
 
                                       46
<PAGE>
for, any Existing Notes, and may terminate or amend the Exchange Offer as
provided herein before the acceptance of such Existing Notes, if:
 
        (a) any action or proceeding is instituted or threatened in any court or
    by or before any governmental agency with respect to the Exchange Offer
    which, in the judgment of the Company upon written advice of counsel, could
    reasonably be expected to materially impair the ability of the Company to
    proceed with the Exchange Offer or any material adverse development has
    occurred in any existing action or proceeding with respect to the Company or
    any of the subsidiaries; or
 
        (b) any law, statute, rule, regulation or interpretation by the staff of
    the Commission is proposed, adopted or enacted, which, in the judgment of
    the Company and based on written advice of counsel, could reasonably be
    expected to materially impair the ability of the Company to proceed with the
    Exchange Offer or materially impair the contemplated benefits of the
    Exchange Offer to the Company; or
 
        (c) any governmental approval has not been obtained, which approval the
    Company shall, in its discretion and based on written advice of counsel,
    deem necessary for the consummation of the Exchange Offer as contemplated
    hereby.
 
    If any of the conditions are not satisfied, the Company may (i) refuse to
accept any Existing Notes and return all tendered Existing Notes to the
tendering holders, (ii) extend the Exchange Offer and retain all Existing Notes
tendered prior to the expiration of the Exchange Offer, subject, however, to the
rights of holders to withdraw such Existing Notes (see "--Withdrawal of
Tenders"), or (iii) waive such unsatisfied conditions with respect to the
Exchange Offer and accept all properly tendered Existing Notes which have not
been withdrawn.
 
    The foregoing conditions are for the sole benefit of the Company and may be
asserted by the Company in whole or in part at any time and from time to time
upon advice of outside counsel. The failure by the Company at any time to
exercise any of the foregoing rights shall not be deemed a waiver of any such
right and such right shall be deemed an ongoing right which may be asserted at
any time and from time to time.
 
    In addition, the Company will not accept for exchange any Existing Notes
tendered and no Exchange Notes will be issued in exchange for any such Existing
Notes, if at such time any stop order is threatened by the Commission or in
effect with respect to the Registration Statement of which this Prospectus is a
part or the qualification of the Indenture under the Trust Indenture Act of
1939, as amended.
 
    The Exchange Offer is not conditioned on any minimum principal amount of
Existing Notes being tendered for exchange.
 
EXCHANGE AGENT
 
    LaSalle National Bank has been appointed as Exchange Agent for the Exchange
Offer. Questions and requests for assistance, requests for additional copies of
this Prospectus or of the Letter of Transmittal and requests for Notice of
Guaranteed Delivery should be directed to the Exchange Agent, addressed as
follows:
 
       LaSalle National Bank
       135 South LaSalle Street
       Chicago, Illinois 60603
       Attention: Diane Swanson
       Telephone: (312) 904-2936
       Facsimile: (312) 904-2236
 
    Delivery to an address other than as set forth above, or transmission of
instructions via a facsimile number other than the one set forth above, will not
constitute a valid delivery.
 
                                       47
<PAGE>
FEES AND EXPENSES
 
    The expenses of soliciting tenders will be borne by the Company. The
principal solicitation is being made by mail; however, additional solicitation
may be made by telegraph, telecopy, telephone or in person by officers and
regular employees of the Company and its affiliates.
 
    The Company has not retained any dealer-manager in connection with the
Exchange Offer and will not make any payments to brokers, dealers, or others
soliciting acceptances of the Exchange Offer. The Company, however, will pay the
Exchange Agent reasonable and customary fees for its services and will reimburse
it for its reasonable out-of-pocket expenses in connection therewith.
 
    The cash expenses to be incurred in connection with the Exchange Offer will
be paid by the Company. Such expenses include fees and expenses of the Exchange
Agent and Trustee, accounting and legal fees and printing costs, among others.
 
ACCOUNTING TREATMENT
 
    The Exchange Notes will be recorded at the same carrying value as the
Existing Notes, which is face value, as reflected in the Company's accounting
records on the date of exchange. Accordingly, no gain or loss for accounting
purposes will be recognized by the Company. The expenses of the Exchange Offer
will be amortized over the term of the Exchange Notes under generally accepted
accounting principles.
 
CONSEQUENCES OF FAILURE TO EXCHANGE
 
    The Existing Notes that are not exchanged for Exchange Notes pursuant to the
Exchange Offer will remain restricted securities. Accordingly, such Existing
Notes may be resold only (i) to the Company, (ii) so long as such Existing Notes
are eligible for resale pursuant to Rule 144A, to a person whom the seller
reasonably believes is a "qualified institutional buyer," as defined in Rule
144A under the Securities Act (a "QIB"), that purchases for its own account or
for the account of a QIB to whom notice is given that the resale, pledge or
transfer is being made in reliance on Rule 144A, (iii) outside the United States
in accordance with Regulation S, (iv) to an institution that is an "accredited
investor" as defined in Rule 501(a)(1), (2), (3) or (7) under the Securities Act
(an "Institutional Accredited Investor") who has certified to the Company and
the Trustee for the Existing Notes that such transferee is an Institutional
Accredited Investor and is acquiring such Notes for investment purposes and not
for distribution, (iv) pursuant to an exemption from registration under the
Securities Act provided by Rule 144 (if applicable) under the Securities Act or
(v) pursuant to an effective registration statement under the Securities Act, in
each case in accordance with any applicable securities laws of any state of the
United States.
 
RESALE OF THE EXCHANGE NOTES
 
    With respect to resales of Exchange Notes, based on interpretations by the
staff of the Commission set forth in no-action letters issued to third parties,
the Company believes that a holder or other person who receives Exchange Notes
in the ordinary course of business, whether or not such person is the holder
(other than (i) a broker-dealer who purchases such Exchange Notes from the
Company to resell pursuant to Rule 144A or any other available exemption under
the Securities Act or (ii) a person that is an "affiliate" of the Company within
the meaning of Rule 405 under the Securities Act) who receives Exchange Notes in
exchange for Existing Notes, and who is not participating, does not intend to
participate, and has no arrangement or understanding with any person to
participate, in the distribution of the Exchange Notes, will be allowed to
resell the Exchange Notes to the public without further registration under the
Securities Act and without delivering to the purchasers of the Exchange Notes a
prospectus that satisfies the requirements of Section 10 of the Securities Act.
However, if any holder acquires Exchange Notes in the Exchange Offer for the
purpose of distributing or participating in a distribution of the Exchange
Notes, such holder cannot rely on the position of the staff of the Commission
enunciated in such
 
                                       48
<PAGE>
no-action letters or any similar interpretive letters, and must comply with the
registration and prospectus delivery requirements of the Securities Act in
connection with any resale transaction, unless an exemption from registration is
otherwise available. Further, each broker-dealer that receives Exchange Notes
for its own account in exchange for Existing Notes, where such Securities were
acquired by such broker-dealer as a result of market-making activities or other
trading activities, must acknowledge that it will deliver a prospectus in
connection with any resale of such Exchange Notes.
 
    As contemplated by these no-action letters and the Registration Agreement,
each holder accepting the Exchange Offer is required to represent to the Company
in the Letter of Transmittal that (i) the Exchange Notes are to be acquired by
the holder or the person receiving such Exchange Notes, whether or not such
person is the holder, in the ordinary course of business, (ii) the holder or any
such other person (other than a broker-dealer referred to in the next sentence)
is not engaging, and does not intend to engage, in the distribution of the
Exchange Notes, (iii) the holder or any such other person has no arrangement or
understanding with any person to participate in the distribution of the Exchange
Notes, (iv) neither the holder nor any such other person is an "affiliate" of
the Company within the meaning of Rule 405 under the Securities Act, and (v) the
holder or any such other person acknowledges that if such holder or other person
participates in the Exchange Offer for the purpose of distributing the Exchange
Notes, it must comply with the registration and prospectus delivery requirements
of the Securities Act in connection with any resale of the Exchange Notes and
cannot rely on those no-action letters. As indicated above, each broker-dealer
that receives any Exchange Notes for its own account in exchange for Existing
Notes must acknowledge that it will deliver a prospectus in connection with any
resale of such Exchange Notes. For a description of the procedures for such
resales by broker-dealers, see "Plan of Distribution."
 
                    CERTAIN FEDERAL INCOME TAX CONSEQUENCES
 
    The following is a summary of the principal U.S. federal income tax
consequences (and, to a limited extent, U.S. federal estate tax consequences)
resulting from (i) the exchange of Existing Notes for Exchange Notes and (ii)
the beneficial ownership of Notes by certain persons. This summary does not
purport to consider all the possible U.S. federal income tax consequences that
may affect a particular Tendering Holder in light of such Tendering Holder's
individual investment circumstances and is not intended to reflect the
particular tax position of any Tendering Holder. It deals only with Notes held
as capital assets. Moreover, except as expressly indicated, it does not address
Tendering Holders that may be subject to special tax rules, such as banks,
insurance companies, dealers in securities or currencies, purchasers that hold
Notes as a hedge against currency risks or as part of a straddle with other
investments or as part of "synthetic security" or other integrated investment
(including a "conversion transaction") comprised of a Note and one or more other
investments, or purchasers that have a "functional currency" other than the U.S.
dollar. Except to the extent discussed below under "Non-U.S. Holders," this
summary is not applicable to non-U.S. persons not subject to U.S. federal income
tax on their worldwide income. This summary is based upon the U.S. federal tax
laws and regulations as now in effect and as currently interpreted and does not
take into account possible changes in such tax laws or such interpretations, any
of which may be applied retroactively. It does not address any description of
gift, estate (except to a limited extent), state, local or foreign taxation that
may be applicable to the Notes or holders thereof. Tendering Holders should
consult their own tax advisors concerning the application of the U.S. federal
tax laws to their participation in the Exchange Offer and the ownership and
disposition of Notes as well as any consequences to them under the laws of any
other taxing jurisdiction.
 
U.S. HOLDERS
 
    The following discussion is limited to certain material U.S. federal income
tax consequences relevant to a holder of a Note that is (i) an individual who is
a citizen or resident of the U.S., (ii) a corporation or other entity taxable as
a corporation created or organized under the laws of the U.S. or any state
thereof (including the District of Columbia), (iii) an estate, the income of
which is subject to U.S. federal income
 
                                       49
<PAGE>
tax regardless of its source, (iv) a trust if the primary supervision over the
administration of such trust can be exercised by a U.S. court and one or more
U.S. persons have the authority to control all substantial decisions of such
trust or (v) a person otherwise subject to U.S. federal income taxation on its
worldwide income (a "U.S. Holder"). Certain material U.S. federal income tax
consequences relevant to a holder other than a U.S. Holder are discussed
separately below.
 
    EXCHANGE OFFER.  The exchange of Existing Notes for Exchange Notes will not
be treated as an "exchange" for U.S. federal income tax purposes to U.S. Holders
because the Exchange Notes will not be considered to differ materially in kind
or extent from the Existing Notes. As a result, there will be no U.S. federal
income tax consequences to Tendering Holders pursuant to the Exchange Offer. A
U.S. Holder should have the same adjusted basis and holding period in the
Exchange Note as it had in the Existing Note immediately before the exchange.
 
    PAYMENTS OF INTEREST.  In general, interest paid on the Notes will be
taxable to a U.S. Holder as ordinary income at the time it is received or
accrued, depending on the Holder's usual method of accounting for U.S. federal
income tax purposes.
 
    SALE, EXCHANGE OR REDEMPTION OF THE NOTES.  Upon the disposition of a Note
by sale, exchange or redemption (including pursuant to an offer by the Company),
a U.S. Holder will generally recognize gain or loss equal to the difference
between (i) the amount of cash plus the fair market value of any property
received upon such sale, exchange or redemption (other than amounts attributable
to accrued interest not yet taken into income) and (ii) the U.S. Holder's
adjusted tax basis in the Note. Generally, a U.S. Holder's adjusted tax basis in
a Note will equal the cost of the Note to the U.S. Holder increased by any
market discount included in income and reduced by any bond premium amortized by
the U.S. Holder.
 
    Assuming the Note is held as a capital asset, such gain or loss (except to
the extent that the market discount rules otherwise provide) will generally
constitute capital gain or loss, which will be either long-term or short-term if
the U.S. Holder is a corporation; or long-term, mid-term or short-term if the
U.S. Holder is a non-corporate entity, depending on the U.S. Holder's holding
period.
 
NON-U.S. HOLDERS
 
    Under present U.S. federal income and estate tax law and subject to the
discussion of backup withholding below:
 
        (a) payments of principal and interest on the Notes by the Company or
    any agent of the Company to any Holder that is not a U.S. Holder or
    partnership created or organized under the laws of the U.S. or any state
    thereof including the District of Columbia (a "Non-U.S. Holder") will not be
    subject to U.S. federal income and withholding tax if the following
    requirements of the "portfolio interest" exception are satisfied: (i) the
    Non-U.S. Holder does not actually or constructively own 10% or more of the
    total combined voting power of all classes of stock of the Company entitled
    to vote, (ii) the Non-U.S. Holder is not a controlled foreign corporation
    that is related to the Company (directly or indirectly) through stock
    ownership and (iii) either (A) the beneficial owner of the Notes certifies
    to the Company or its agent, under penalties of perjury, that he is not a
    "United States person" (as defined by the Code) and provides his name and
    address, or (B) a securities clearing organization, bank or other financial
    institution that holds customers' securities in the ordinary course of its
    trade or business (a "financial institution") and holds the Notes on behalf
    of its beneficial owner certifies to the Company or its agent under
    penalties of perjury that such statement has been received from the
    beneficial owner by it or by a financial institution between it and the
    beneficial owner and furnishes the payor with a copy thereof;
 
        (b) except as otherwise provided below, a Non-U.S. Holder will not be
    subject to U.S. federal income and withholding tax on gain realized on the
    sale, exchange or redemption of a Note provided
 
                                       50
<PAGE>
    that, in the case of any gain representing accrued interest, the conditions
    described in (a) above are satisfied; and
 
        (c) a Note held by an individual who at the time of death is not a
    citizen or resident of the U.S. will not be subject to U.S. federal estate
    tax as a result of such individual's death if, at the time of such death,
    the individual did not actually or constructively own 10% or more of the
    total combined voting power of all classes of stock of the Company entitled
    to vote and the income on the Notes or Exchange Notes would not have been
    effectively connected with the conduct of a trade or business by the
    individual in the U.S.
 
    If a Non-U.S. Holder is engaged in a trade or business in the U.S. and
interest on the Note is effectively connected with the conduct of such trade or
business, the Non-U.S. Holder, although exempt from the withholding tax
discussed in the preceding paragraph (provided that such holder properly claims
such exemption), may be subject to U.S. federal income tax on such interest in
the same manner as if it were a U.S. Holder. In addition, if such Non-U.S.
Holder is a foreign corporation, it may be subject to a branch profits tax equal
to 30% of its effectively connected earnings and profits for the taxable year,
subject to adjustments. For this purpose, interest on the Note will be included
in such foreign corporation's effectively connected earnings and profits.
 
    Any gain realized by the Non-U.S. Holder upon the sale, exchange or
retirement of a Note generally will not be subject to U.S. federal income tax
unless (i) such gain or income is effectively connected with a trade or business
conducted by the Non-U.S. Holder in the U.S., (ii) in the case of a Non-U.S.
Holder who is an individual, such individual is present in the U.S. for 183 days
or more in the taxable year of such sale, exchange or retirement, and certain
other conditions are met, or (iii) the Non-U.S. Holder is subject to tax
pursuant to the provisions of the Code applicable to certain U.S. expatriates.
 
    If a Non-U.S. Holder cannot satisfy the requirements of the "portfolio
interest" exception described in relevant part above, payments of interest to
the Non-U.S. Holder will be subject to U.S. federal income and withholding tax
at a rate of 30% unless the beneficial owner of the Note provides the Company or
its agent with a properly executed (i) Internal Revenue Service Form 1001 (or
successor form) claiming an exemption from withholding under the benefit of a
tax treaty, or (ii) Internal Revenue Service Form 4224 (or successor form)
stating that the interest paid on the Note is not subject to U.S. federal income
and withholding tax because such interest income is effectively connected with
the beneficial owner's conduct of a trade or business in the U.S.
 
    Recently adopted Treasury Regulations not yet in effect (the "Final
Regulations"), would alter the foregoing rules in certain respects. In general,
the Final Regulations are generally effective for payments made after December
31, 1998. Under the Final Regulations, a Non-U.S. Holder seeking an exemption
under (i) or (ii) of the preceding paragraph would generally be required to
provide a beneficial owner certificate on Form W-8, which form may include,
among other things, the Non-U.S. Holder's taxpayer identification number. The
Final Regulations also provide special rules to determine whether, for purposes
of determining the applicability of a tax treaty, interest paid to a Non-U.S.
Holder that is an entity should be treated as paid to the entity or those
holding an interest in the entity. The foregoing is not intended to be a
complete discussion of the provisions of the Final Regulations, and Non-U.S.
Holders are urged to consult their advisors with respect to the effect that the
Final Regulations will have when they become effective.
 
INFORMATION REPORTING AND BACKUP WITHHOLDING
 
    Under the Code, a U.S. Holder of a Note may be subject, under certain
circumstances, to information reporting and/or backup withholding at a 31% rate
with respect to payments of interest or the gross proceeds from the sale,
exchange or redemption of a Note. This withholding applies only if a U.S. Holder
(i) fails to furnish its social security or other taxpayer identification number
("TIN") within a reasonable time after a request therefor, (ii) furnishes an
incorrect TIN, (iii) fails to report interest or dividends
 
                                       51
<PAGE>
properly, or (iv) fails, under certain circumstances, to provide a certified
statement, signed under penalty or perjury, that the TIN provided is its correct
number and that it is not subject to backup withholding. Any amount withheld
from a payment to a U.S. Holder under the backup withholding rules is allowable
as a credit (and may entitle such holder to a refund) against such holder's U.S.
federal income tax liability, provided that the required information is
furnished to the IRS. Certain persons are exempt from backup withholding,
including corporations, tax-exempt organizations, qualified pension and profit
sharing trusts and individual retirement accounts. U.S. Holders of Notes should
consult their tax advisors as to their qualification for exemption from
withholding and the procedure for obtaining such exemption.
 
    Under current Treasury Regulations, backup withholding and information
reporting will not apply to payments made by the Company or any agent thereof
(in its capacity as such) to a Non-U.S. Holder of a Note if such holder has
provided the required certification that it is not a United States person as set
forth in clause (iii) in the first paragraph under "Non-U.S. Holders," or has
otherwise established an exemption (provided that neither the Company nor its
agent has actual knowledge that the holder is a United States person or that the
conditions of any exemption are not in fact satisfied).
 
    Payment of the proceeds from the sale of a Note to or through a foreign
office of a broker generally will not be subject to information reporting or
backup withholding, except that information reporting may apply to such payments
if the broker is a (i) United States person, (ii) a controlled foreign
corporation for U.S. tax purposes or (iii) a foreign person 50% or more of whose
gross income from all sources for the three-year period ending with the close if
its taxable year preceding the payment was effectively connected with a U.S.
trade or business. Payment of the proceeds from a sale of a Note to or through
the U.S. office of a broker is subject to information reporting and backup
withholding unless the holder or beneficial owner certifies as to its taxpayer
identification number or otherwise establishes an exemption from information
reporting and backup withholding.
 
    The Final Regulations may change the procedures for exemption from backup
withholding. These regulations are generally effective for payments made after
December 31, 1998, subject to certain transition rules. Non-U.S. Holders should
consult their own tax advisors with respect to the impact, it any, of the Final
Regulations.
 
                              PLAN OF DISTRIBUTION
 
    Each broker-dealer that receives Exchange Notes for its own account pursuant
to the Exchange Offer must acknowledge that it will deliver a prospectus in
connection with any resale of such Exchange Notes. This Prospectus, as it may be
amended or supplemented from time to time, may be used by a broker-dealer in
connection with resales of Exchange Notes received in exchange for Existing
Notes, where such Exchange Notes were acquired as a result of market-making
activities or other trading activities. The Company has agreed that, for a
period of 180 days (exclusive of any period during which any stop order shall be
in effect suspending the effectiveness of the Registration Statement) after the
Expiration Date, it will make this Prospectus, as amended or supplemented,
available to any broker-dealer for use in connection with any such resale. In
addition, until             , 1998 all dealers effecting transactions in the
Exchange Notes may be required to deliver a prospectus.
 
    The Company will not receive any proceeds from any sale of Exchange Notes by
broker-dealers. Exchange Notes received by broker-dealers for their own account
pursuant to the Exchange Offer may be sold from time to time in one or more
transactions in the over-the-counter market, in negotiated transactions, through
the writing of options on the Exchange Notes, or a combination of such methods
of resale, at market prices prevailing at the time of resale, at prices related
to such prevailing market prices or negotiated prices. Any such resale may be
made directly to purchasers or to or through brokers or dealers who may receive
compensation in the form of commission or concessions from any such
broker-dealer and/ or the purchasers of any such Exchange Notes. Any
broker-dealer that resells Exchange Notes that were received by it for its own
account pursuant to the Exchange Offer and any broker or dealer that
 
                                       52
<PAGE>
participates in a distribution of such Exchange Notes may be deemed to be an
"underwriter" within the meaning of the Securities Act and any profit on any
such resale of Exchange Notes and any commissions or concessions received by any
such persons may be deemed to be underwriting compensation under the Securities
Act. The Letter of Transmittal states that, by acknowledging that it will
deliver and by delivering a prospectus, a broker-dealer will not be deemed to
admit that it is an "underwriter" within the meaning of the Securities Act.
 
    For a period of 180 days after the Expiration Date (exclusive of any period
during which any stop order shall be in effect suspending the effectiveness of
the Registration Statement), the Company will promptly send additional copies of
this Prospectus and any amendment or supplement to this Prospectus to any
broker-dealer that requests such documents pursuant to a Letter of Transmittal.
The Company has agreed to pay all expenses incident to the Exchange Offer
(including the expenses of one counsel for certain holders of the Existing
Notes) other than commissions or concessions of any brokers or dealers and will
indemnify the holders of the Existing Notes (including any broker-dealers)
against certain liabilities, including liabilities under the Securities Act.

                     INFORMATION NOT REQUIRED IN PROSPECTUS
 
ITEM 20. INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
    Section 1006(B)(7) of the Oklahoma General Corporation Act permits an
Oklahoma corporation to include a provision in its Certificate of Incorporation
limiting a director's liability to the corporation or its stockholders for
monetary damages for breaches of fiduciary duty as a director.
 
    The Registrant's Certificate of Incorporation provides that, pursuant to
Oklahoma law, its directors shall not be liable for monetary damages for breach
of the directors' fiduciary duty of care to the Registrant and its stockholders.
The provision in the Certificate of Incorporation does not eliminate the duty of
care and, in appropriate circumstances, equitable remedies such as injunctive or
other forms of non-monetary relief will remain available under Oklahoma law. In
addition, each director will continue to be subject to liability for breach of
the director's duty of loyalty to the Registrant, as well as for acts or
omissions not in good faith or involving intentional misconduct, for knowing
violations of law, for actions leading to improper personal benefit to the
director, and for payment of dividends or approval of stock repurchases or
redemptions that are unlawful under Oklahoma law. The provision also does not
affect a director's responsibilities under any other law, such as the state or
federal securities laws.
 
    Under Section 1031 of the Oklahoma General Corporation Act, the Registrant
has broad powers to indemnify its directors and officers against liabilities
they may incur in such capacities, including liabilities under the Securities
Act of 1933, as amended (the "Securities Act").
 
    The Registrant's Certificate of Incorporation provides that the Registrant
shall indemnify its directors and officers to the fullest extent permitted by
Oklahoma law. The Certificate of Incorporation requires the Registrant to
indemnify such persons against expenses, judgments, fines, settlements and other
amounts incurred in connection with any proceeding, whether actual or
threatened, to which any such person may be made a party by reason of the fact
that such person is or was a director or an officer of the Registrant or any of
its affiliated enterprises, provided such person acted in good faith and in a
manner such person reasonably believed to be in or not opposed to the best
interests of the Registrant, and, with respect to any criminal proceeding, had
no reasonable cause to believe his conduct was unlawful. However, in the case of
a derivative action, an officer or director will not be entitled to
indemnification in respect of any claim, issue or matter as to which such person
is adjudged to be liable to the Registrant, unless and only to the extent that
the court in which the action was brought determines that such person is fairly
and reasonably entitled to indemnity for expenses.
 
    The Registrant has entered into Indemnification Agreements with each
director of the Registrant which require the Registrant to indemnify such
persons against certain liabilities and expenses incurred by any such persons by
reason of their status or service as directors of the Registrant. The
Indemnification Agreements also set forth procedures that will apply in the
event of a claim for indemnification under such agreements. In addition, the
Indemnification Agreements require that the Registrant use commercially
reasonable efforts to maintain policies of directors' liability insurance.
 
    At present, there is no pending litigation or proceeding involving a
director or officer of the Registrant as to which indemnification is being
sought nor is the Registrant aware of any threatened litigation that may result
in claims for indemnification by any officer or director.

ITEM 22. UNDERTAKINGS.
 
    The undersigned Registrant hereby undertakes 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 section 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 the
registration statement shall be deemed to be a new registration statement
relating to the securities offered therein, and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.
 
    Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the foregoing provisions, or otherwise, the Registrant
has been advised that in the opinion of the 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 Registrant of expenses incurred
or paid by a director, officer or controlling person of the Registrant in the
successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the Registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Act and will be governed by the final adjudication of
such issue.

request, and to send the incorporated documents by first class mail or other
equally prompt means. This includes information contained in documents filed
subsequent to the effective date of the Registration Statement through the date
of responding to the request.
 
    The undersigned Registrant hereby undertakes to supply by means of a
post-effective amendment all information concerning a transaction, and the
company being acquired involved therein, that was not the subject of and
included in the Registration Statement when it became effective.

For the purposes of this definition, "control" (including, with correlative

as of the date of determination, the remainder of: (a) the sum of (i) 
discounted future net revenues from proved oil and gas reserves of the 
Company and its Subsidiaries calculated in accordance with SEC guidelines 
(including adjustment for prices payable to the Company and its Subsidiaries 
under Oil and Gas Hedging Contracts) before any state, Federal or foreign

The signature shall be conclusive evidence that the Security has been 
authenticated under this Indenture.

     The Trustee shall authenticate and deliver Securities for original issue 
upon a written order of the Company signed by two Officers or by an Officer 
and either an Assistant Treasurer or an Assistant Secretary of the Company.  
Such order shall specify the amount of the Securities to be authenticated and 
the date on which the original issue of Securities is to be authenticated.  
The aggregate principal amount of Securities outstanding at any time may not 
exceed that amount except as provided in Section 2.07.

     The Trustee may appoint an authenticating agent reasonably acceptable to 
the Company to authenticate the Securities.  Unless limited by the terms of 
such appointment, an authenticating agent may authenticate Securities 
whenever the Trustee may do so.  Each reference in this Indenture to 
authentication by the Trustee includes authentication by such agent.  An 
authenticating agent has the same rights as any Registrar, Paying Agent or 
agent for service of notices and demands.

     SECTION 2.03.  REGISTRAR AND PAYING AGENT.  The Company shall maintain 
an office or agency where Securities may be presented for registration of 
transfer or for exchange (the "Registrar") and an office or agency where 
Securities may be presented for payment (the "Paying Agent").  The Registrar 
shall keep a register of the Securities and of their transfer and exchange.  
The Company may have one or more co-registrars and one or more additional 
paying agents.  The term "Paying Agent" includes any additional paying agent.

     The Company shall enter into an appropriate agency agreement with any 
Registrar, Paying Agent or co-registrar not a party to this Indenture, which 
shall incorporate the terms of the TIA.  The agreement shall implement the 
provisions of this Indenture that relate to such agent.  The Company shall 
notify the Trustee of the name and address of any such agent.  If the Company 
fails to maintain a Registrar or Paying Agent to the knowledge of the 
Trustee, the Trustee shall act as such and shall be entitled to appropriate 
compensation therefor pursuant to Section 7.07.  The Company or any of its 
domestically incorporated Wholly-Owned Subsidiaries may act as Paying Agent, 
Registrar, co-registrar or transfer agent.

     The Company initially appoints the Trustee as Registrar and Paying Agent 
in connection with the Securities.

     SECTION 2.04.  PAYING AGENT TO HOLD MONEY IN TRUST.  Prior to each due 
date of the principal and interest on any Security, the Company shall deposit 
with the Paying Agent a sum sufficient to pay such principal and interest 
when so becoming due.  The Company shall require each Paying Agent (other 
than the Trustee) to agree in writing that the Paying Agent shall hold in 
trust for the benefit of Securityholders or the Trustee all money held by the 
Paying Agent for the payment of principal of or interest on the Securities 
and shall notify the Trustee of any default by the Company in making any such 
payment.  If the Company or a Subsidiary acts as Paying Agent, it shall 
segregate the money held by it as Paying Agent and hold it as a separate 
trust fund.  The Company at any time may require a Paying Agent to pay all 
money held by it to the Trustee and to account for any funds disbursed by the 
Paying Agent.  Upon complying with this Section, the Paying Agent shall have 
no further liability for the money delivered to the Trustee.

     SECTION 2.05.  SECURITYHOLDER LISTS.  The Trustee shall preserve in as 
current a form as is reasonably practicable the most recent list available to 
it of the names and addresses of Securityholders.  If the Trustee is not the 
Registrar, the Company shall furnish to the Trustee, in writing at least five 
Business Days before each interest payment date and at such other times as 
the Trustee may request in writing, a list in such form and as of such date 
as the Trustee may reasonably require of the names and addresses of 
Securityholders.

     SECTION 2.06.  TRANSFER AND EXCHANGE.  The Securities shall be issued in 
registered form and shall be transferable only upon the surrender of a 
Security for registration of transfer.  When a Security is presented to the 
Registrar or a co-registrar with a request to register a transfer, the 
Registrar shall register the transfer as requested if the requirements of 
Section 8-401(1) of the Uniform Commercial Code are met.  When Securities are 
presented to the Registrar or a co-registrar with a request to exchange them 
for an equal principal amount of Securities of other denominations, the 
Registrar shall make the exchange as requested if the same requirements are 
met.  To permit registration of transfers and exchanges, the Company shall 
execute and the Trustee shall authenticate Securities at the Registrar's or 
co-registrar's request.  The Company may require payment of a sum sufficient 
to pay all taxes, assessments or other governmental charges in connection 
with any transfer or exchange pursuant to this Section.  The Company shall 
not be required to make and the Registrar need not register transfers or 
exchanges of Securities selected for redemption (except, in the case of 
Securities to be redeemed in part, the portion thereof not to be redeemed) or 
any Securities for a period of 15 days before a selection of Securities to be 
redeemed or 15 days before an interest payment date.

     Prior to the due presentation for registration of transfer of any 
Security, the Company, the Trustee, the Paying Agent, the Registrar or any 
co-registrar may deem and treat the person in whose name a Security is 
registered as the absolute owner of such Security for the purpose of 
receiving payment of principal of and interest on such Security and for all 
other purposes whatsoever, whether or not such Security is overdue, and none 
of the Company, the Trustee, the Paying Agent, the Registrar or any 
co-registrar shall be affected by notice to the contrary.


                                      12

<PAGE>

     All Securities issued upon any transfer or exchange pursuant to the 
terms of this Indenture will evidence the same debt and will be entitled to 
the same benefits under this Indenture as the Securities surrendered upon 
such transfer or exchange.

     SECTION 2.07.  REPLACEMENT SECURITIES.  If a mutilated Security is 
surrendered to the Registrar or if the Holder of a Security claims that the 
Security has been lost, destroyed or wrongfully taken, the Company shall 
issue and the Trustee shall authenticate a replacement Security if the 
requirements of Section 8-405 of the Uniform Commercial Code are met and the 
Holder satisfies any other reasonable requirements of the Trustee.  If 
required by the Trustee or the Company, such Holder shall furnish an 
indemnity bond sufficient in the judgment of the Company and the Trustee to 
protect the Company, the Trustee, the Paying Agent, the Registrar and any 
co-registrar from any loss which any of them may suffer if a Security is 
replaced.  The Company and the Trustee may charge the Holder for their 
expenses in replacing a Security.

     Every replacement Security is an additional obligation of the Company.

     SECTION 2.08.  OUTSTANDING SECURITIES.  Securities outstanding at any 
time are all Securities authenticated by the Trustee except for those 
canceled by it, those delivered to it for cancelation and those described in 
this Section as not outstanding.  A Security does not cease to be outstanding 
because the Company or an Affiliate of the Company holds the Security.

     If a Security is replaced pursuant to Section 2.07, it ceases to be 
outstanding unless the Trustee and the Company receive proof satisfactory to 
them that the replaced Security is held by a bona fide purchaser.

     If the Paying Agent segregates and holds in trust, in accordance with 
this Indenture, on a redemption date or maturity date money sufficient to pay 
all principal and interest payable on that date with respect to the 
Securities (or portions thereof) to be redeemed or maturing, as the case may 
be, then on and after that date such Securities (or portions thereof) cease 
to be outstanding and interest on them ceases to accrue.

     SECTION 2.09.  TEMPORARY SECURITIES.  Until definitive Securities are 
ready for delivery, the Company may prepare and the Trustee shall authenticate
temporary Securities.  Temporary Securities shall be substantially in the 
form of definitive Securities but may have variations that the Company 
considers appropriate for temporary Securities.  Without unreasonable delay, 
the Company shall prepare and the Trustee shall authenticate definitive 
Securities and deliver them in exchange for temporary Securities.

     SECTION 2.10.  CANCELATION.  The Company at any time may deliver 
Securities to the Trustee for cancelation.  The Registrar and the Paying 
Agent shall forward to the Trustee any Securities surrendered to them for 
registration of transfer, exchange or payment.  The Trustee and no one else 
shall cancel and destroy (subject to the record retention requirements of the 
Exchange Act) all Securities surrendered for registration of transfer, 
exchange, payment or cancelation and 


                                      13

<PAGE>

deliver a certificate of such destruction to the Company unless the Company 
directs the Trustee to deliver canceled Securities to the Company.  The 
Company may not issue new Securities to replace Securities it has redeemed, 
paid or delivered to the Trustee for cancelation.

     SECTION 2.11.  DEFAULTED INTEREST.  If the Company defaults in a payment 
of interest on the Securities, the Company shall pay defaulted interest (plus 
interest on such defaulted interest to the extent lawful) in any lawful 
manner.  The Company may pay the defaulted interest to the persons who are 
Securityholders on a subsequent special record date.  The Company shall fix 
or cause to be fixed any such special record date and payment date to the 
reasonable satisfaction of the Trustee and shall promptly mail to each 
Securityholder a notice that states the special record date, the payment date 
and the amount of defaulted interest to be paid.

     SECTION 2.12.  CUSIP NUMBERS.  The Company in issuing the Securities may 
use "CUSIP" numbers (if then generally in use) and, if so, the Trustee shall 
use "CUSIP" numbers in notices of redemption as a convenience to Holders; 
PROVIDED, HOWEVER, that any such notice may state that no representation is 
made as to the correctness of such numbers either as printed on the 
Securities or as contained in any notice of a redemption and that reliance 
may be placed only on the other identification numbers printed on the 
Securities, and any such redemption shall not be affected by any defect in or 
omission of such numbers.

                                  ARTICLE 3

                                  REDEMPTION

     SECTION 3.01.  NOTICES TO TRUSTEE.  If the Company elects to redeem 
Securities pursuant to paragraph 5 of the Securities, it shall notify the 
Trustee in writing of the redemption date, the principal amount of Securities 
to be redeemed and the paragraph of the Securities pursuant to which the 
redemption will occur.  

     The Company shall give each notice to the Trustee provided for in this 
Section at least 60 days before the redemption date unless the Trustee 
consents to a shorter period.  Such notice shall be accompanied by an 
Officers' Certificate and an Opinion of Counsel from the Company to the 
effect that such redemption will comply with the conditions herein.  

     SECTION 3.02.  SELECTION OF SECURITIES TO BE REDEEMED.  If fewer than 
all the Securities are to be redeemed, the Trustee shall select the 
Securities to be redeemed pro rata or by lot or by a method that complies 
with applicable legal and securities exchange requirements, if any, and that 
the Trustee in its sole discretion shall deem to be fair and appropriate and 
in accordance with methods generally used at the time of selection by 
fiduciaries in similar circumstances.  The Trustee shall make the selection 
from outstanding Securities not previously called for redemption.  The 
Trustee may select for redemption portions of the principal of Securities 
that have denominations larger than $1,000.  Securities and portions of them 
the Trustee selects shall be in amounts of $1,000 or a whole multiple of 
$1,000.  Provisions of this Indenture that apply to Securities called for 


                                      14

<PAGE>

redemption also apply to portions of Securities called for redemption.  The 
Trustee shall notify the Company promptly of the Securities or portions of 
Securities to be redeemed.

     SECTION 3.03.  NOTICE OF REDEMPTION.  At least 30 days but not more than 
60 days before a date for redemption of Securities, the Company shall mail a 
notice of redemption by first-class mail to each Holder of Securities to be 
redeemed at such Holder's registered address, with copies of such notices to 
the Trustee.

     The notice shall identify the Securities to be redeemed and shall state:

          (1) the redemption date;

          (2) the redemption price;

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

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

          (5) if fewer than all the outstanding Securities are to be redeemed,
     the identification and principal amounts of the particular Securities to 
     be redeemed;

          (6) that, unless the Company defaults in making such redemption 
     payment or the Paying Agent is prohibited from making such payment pursuant
     to the terms of this Indenture, interest on Securities (or portion thereof)
     called for redemption ceases to accrue on and after the redemption date;

          (7) the paragraph of the Securities pursuant to which the Securities 
     called for redemption are being redeemed; and

          (8) that no representation is made as to the correctness or accuracy 
     of the CUSIP number, if any, listed in such notice or printed on the 
     Securities.

     At the Company's request, the Trustee shall give the notice of 
redemption in the Company's name and at the Company's expense.  In such 
event, the Company shall provide the Trustee with the information required by 
this Section.

     SECTION 3.04.  EFFECT OF NOTICE OF REDEMPTION.  Once notice of 
redemption is mailed, Securities called for redemption become due and payable 
on the redemption date and at the redemption price stated in the notice.  
Upon surrender to the Paying Agent, such Securities shall be paid at the 
redemption price stated in the notice, plus accrued interest to the 
redemption date.  Failure to give notice or any defect in the notice to any 
Holder shall not affect the validity of the notice to any other Holder.


                                      15

<PAGE>

     SECTION 3.05.  DEPOSIT OF REDEMPTION PRICE.  On or before the redemption 
date, the Company shall deposit with the Paying Agent (or, if the Company or 
a Subsidiary is the Paying Agent, shall segregate and hold in trust) money 
sufficient to pay the redemption price of and accrued interest on all 
Securities to be redeemed on that date other than Securities or portions of 
Securities called for redemption which have been delivered by the Company to 
the Trustee for cancelation.

     SECTION 3.06.  SECURITIES REDEEMED IN PART.  Upon surrender of a 
Security that is redeemed in part, the Company shall execute and the Trustee 
shall authenticate for the Holder (at the Company's expense) a new Security 
equal in principal amount to the unredeemed portion of the Security 
surrendered.

                                 ARTICLE 4

                                 COVENANTS

     SECTION 4.01.  PAYMENT OF SECURITIES.  The Company shall promptly pay 
the principal of and interest on the Securities on the dates and in the 
manner provided in the Securities and in this Indenture.  Principal and 
interest shall be considered paid on the date due if on such date the Trustee 
or the Paying Agent holds in accordance with this Indenture money sufficient 
to pay all principal and interest then due.

     The Company shall pay interest on overdue principal at the rate 
specified therefor in the Securities, and it shall pay interest on overdue 
installments of interest at the same rate to the extent lawful.

     SECTION 4.02.  SEC REPORTS.  The Company shall file with the Trustee and 
provide Securityholders, within 15 days after it files them with the SEC, 
copies of its annual report and the information, documents and other reports 
which the Company is required to file with the SEC pursuant to Section 13 or 
15(d) of the Exchange Act.  Notwithstanding that the Company may not be 
required to remain subject to the reporting requirements of Section 13 or 
15(d) of the Exchange Act, the Company shall continue to file with the SEC 
and provide the Trustee and Securityholders with such annual reports and such 
information, documents and other reports as are specified in Sections 13 and 
15(d) of the Exchange Act and applicable to a U.S. corporation subject to 
such Sections, such information, documents and reports to be so filed and 
provided at the times specified for the filing of such information, documents 
and reports under such Sections.  The Company also shall comply with the 
other provisions of TIA Section 314(a).  Notwithstanding anything to the 
contrary herein, the Trustee shall have no duty to review such documents for 
purposes of determining compliance with any provisions of this Indenture.

     SECTION 4.03.  COMPLIANCE CERTIFICATE.  The Company shall deliver to the 
Trustee within 120 days after the end of each fiscal year of the Company an 
Officers' Certificate stating that in the course of the performance by the 
signers of their duties as Officers of the Company they would normally have 
knowledge of any Default and whether or not the signers know of any Default 
that 


                                      16

<PAGE>

occurred during such period.  If they do, the certificate shall describe the 
Default, its status and what action the Company is taking or proposes to take 
with respect thereto.  The Company also shall comply with TIA Section 314(a)(4).
The Company agrees to notify the Trustee of any change in its fiscal year.

     SECTION 4.04.  FURTHER INSTRUMENTS AND ACTS.  Upon request of the 
Trustee, the Company will execute and deliver such further instruments and do 
such further acts as may be reasonably necessary or proper to carry out more 
effectively the purpose of this Indenture.

     SECTION 4.05.  CORPORATE EXISTENCE.  Subject to the provisions of 
Article 5, the Company will do or cause to be done all things necessary to 
and will cause each of its Subsidiaries to preserve and keep in full force 
and effect its corporate existence, material rights (charter and statutory) 
and franchises of the Company and each of its Subsidiaries; PROVIDED, 
HOWEVER, that the Company shall not be required to preserve any such material 
right or franchise or the corporate existence of any of its Subsidiaries if 
(a) the preservation thereof is no longer desirable in the conduct of the 
business of the Company or such Subsidiary and (b) the loss thereof is not 
disadvantageous in any material respect to the Holders of the Securities.

     SECTION 4.06.  LIMITATION ON LIENS.  Subject to Article 8 (to the extent 
it is applicable to the Securities) the Company will not, and will not permit 
any of its Subsidiaries to, create, incur or otherwise cause or suffer to 
exist or become effective any Liens of any kind upon any Principal Property 
or any shares of stock or Indebtedness of any Subsidiary that owns or leases 
any Principal Property (whether such Principal Property, shares of stock or 
Indebtedness are now owned or hereafter acquired) unless all payments due 
under this Indenture and the Securities are secured on an equal and ratable 
basis with the obligations so secured until such time as such obligation is 
no longer secured by a Lien, except for Permitted Liens.

     The covenant contained in this Section 4.06 will be subject to the 
provision for exempted Indebtedness in Section 4.08.

     SECTION 4.07.  LIMITATION ON SALE AND LEASEBACK TRANSACTIONS.  Subject 
to Article 8 (to the extent it is applicable to the Securities), neither the 
Company nor any Subsidiary will enter into any Sale and Leaseback Transaction 
with respect to any Principal Property unless either (a) the Company or such 
Subsidiary would be entitled, pursuant to the provisions of this Indenture, 
to incur Indebtedness secured by a Lien on the property to be leased without 
equally and ratably securing the Securities or (b) the Company, within 180 
days after the effective date of such transaction, applies to the voluntary 
retirement of its funded debt an amount equal to the value of such 
transaction, defined as the greater of the net proceeds of the sale of the 
property leased in such transaction or the fair value, in the opinion of the 
Board of Directors, of the leased property at the time such transaction was 
entered into.

     The covenant contained in this Section 4.07 will be subject to the 
provision for exempted Indebtedness in Section 4.08.

     SECTION 4.08.  EXEMPTED INDEBTEDNESS.  Notwithstanding the provisions 
contained in Sections 4.06 and 4.07, the Company and its Subsidiaries may 
issue, assume or guarantee Indebtedness secured by a Lien without securing 
the Securities, or may enter into Sale and Leaseback Transactions without 
retiring funded debt, or enter into a combination of such transactions, if 
the sum of the principal amount of all such Indebtedness and the aggregate 
value of all such Sale and Leaseback Transactions does not at any time exceed 
15% of the Adjusted Consolidated Net Tangible Assets of the Company.  For the 
purposes of any calculation pursuant to this Section 4.08, the Trustee may 
rely on an Officers' Certificate setting forth such calculation.

     SECTION 4.09.  WAIVER OF STAY; EXTENSION OF USURY LAWS.  The Company 
covenants (to the extent that it may lawfully do so) that it will not at any 
time insist upon, plead, or in any manner whatsoever claim or take the 
benefit or advantage of, any stay or extension law or any usury law or other 
law that would prohibit or forgive the Company from paying all or any portion 
of the principal of, or interest on the Securities as contemplated herein or 
in the Securities, wherever enacted, now or at any time hereafter in force, 
or that may affect the covenants or the performance of this Indenture; and 
(to the extent that it may lawfully do so) the Company hereby expressly 
waives all benefit or advantage of any such law, and covenants that it will 
not hinder, delay or impede the execution of any power herein granted to the 
Trustee, but will suffer and permit the execution of every such power as 
though no such law had been enacted.

Company with, or merger of the Company into, any other Person or any 
conveyance, transfer or lease of the properties and assets of the Company 
substantially as an entirety in accordance with Section 5.01, the successor 
Person formed by such consolidation or into which the Company is merged or

     taking possession by a custodian, receiver, liquidator, assignee, trustee,
     sequestrator or other similar official of the Company or a Significant 
     Subsidiary or of any substantial part of their respective properties, or 
     the making by either the Company or a Significant Subsidiary of an 
     assignment for the benefit of creditors, or the admission by either the 
     Company or a Significant Subsidiary in writing of an inability to pay the
     debts of either the Company or a Significant Subsidiary generally as they
     become due, or the taking of corporate action by the Company or a 
     Significant Subsidiary in furtherance of any such action.

     SECTION 6.02.  ACCELERATION OF MATURITY; RESCISSION AND ANNULMENT.  If 
an Event of Default (other than an Event of Default specified in Section 
6.01(4) or 6.01(5)) occurs and is continuing, then in every such case the 
Trustee or the Holders of not less than 25% in principal amount of the 
outstanding Securities may declare the principal of all the Securities to be 
due and payable immediately, by a notice in writing to the Company (and to 
the Trustee if given by Holders), 


                                      20

<PAGE>

and upon any such declaration such principal shall become immediately due and 
payable.  If an Event of Default specified in Section 6.01(4) or 6.01(5) 
occurs, the principal of all the Securities shall automatically, and without 
any declaration or other action on the part of the Trustee or any Holder, 
become immediately due and payable.

     At any time after such a declaration of acceleration has been made and 
before a judgment or decree for payment of the money due has been obtained by 
the Trustee as hereinafter in this Article 6 provided, the Holders of a 
majority in principal amount of the outstanding Securities, by written notice 
to the Company and the Trustee, may (but are not required to) rescind and 
annul such declaration and its consequences if

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

               (A) all overdue interest on all Securities,

               (B) the principal of (and premium, if any, on) any Securities
          which have become due otherwise than by such declaration of 
          acceleration and interest thereon at the rate borne by the Securities,

               (C) to the extent that payment of such interest is lawful, 
          interest upon overdue interest at the rate borne by the Securities, 
          and

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

     and

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

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

     SECTION 6.03.  COLLECTION OF INDEBTEDNESS AND SUITS FOR ENFORCEMENT BY 
TRUSTEE.  If

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

          (2) default is made in the payment of the principal of (or premium, 
     if any, on) any Security at the Stated Maturity thereof,


                                      21

<PAGE>

the Trustee is authorized to recover judgment in its own name and as trustee 
of an express trust against the Company for the whole amount then due and 
payable on such Securities for principal (and premium, if any) and interest, 
and, to the extent that payment of such interest shall be legally 
enforceable, interest on any overdue principal (and premium, if any) and on 
any overdue interest, at the rate borne by the Securities, and, in addition 
thereto, such further amount as shall be sufficient to cover the costs and 
expenses of collection, including the reasonable compensation, expenses, 
disbursements and advances of the Trustee, its agents and counsel.

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

     SECTION 6.04.  TRUSTEE MAY FILE PROOFS OF CLAIM.  In case of any 
judicial proceeding relative to the Company (or any other obligor upon the 
Securities), its property or its creditors, the Trustee shall be entitled and 
empowered, by intervention in such proceeding or otherwise,

          (1) to file and prove a claim for the whole amount of principal and 
     interest owing and unpaid in respect of the Securities and to file such 
     other papers or documents as may be necessary or advisable in order to 
     have the claims of the Trustee (including any claim for the reasonable 
     compensation, expenses, disbursements and advances of the Trustee, its 
     agents and counsel) and of the Holders allowed in such judicial proceeding,
     and

          (2) to collect and receive any moneys or other property payable or 
     deliverable on any such claim and to distribute the same; 

and any custodian, receiver, assignee, trustee, liquidator, sequestrator or 
other similar official in any such judicial proceeding is hereby authorized 
and directed by each Holder to make such payments to the Trustee and, in the 
event that the Trustee shall consent to the making of such payments directly 
to the Holders, to pay to the Trustee any amount due it for the reasonable 
compensation, expenses, disbursements and advances of the Trustee, its agents 
and counsel, and any other amounts due the Trustee under Section 7.07.

     No provision of this Indenture shall be deemed to authorize the Trustee 
to authorize or consent to or accept or adopt on behalf of any Holder any 
plan of reorganization, arrangement, adjustment or composition affecting the 
Securities or the rights of any Holder thereof or to authorize the Trustee to 
vote in respect of the claim of any Holder in any such proceeding; PROVIDED, 
HOWEVER, that the Trustee may, on behalf of the Holders, vote for the 
election of a trustee in bankruptcy or similar official and be a member of a 
creditors' or other similar committee.

     SECTION 6.05.  TRUSTEE MAY ENFORCE CLAIMS WITHOUT POSSESSION OF 
SECURITIES.  All rights of action and claims under this Indenture or the 
Securities may be prosecuted and enforced by the 


                                      22

<PAGE>

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

     SECTION 6.06.  APPLICATION OF MONEY COLLECTED.  Any money collected by 
the Trustee pursuant to this Article 6 shall be applied in the following 
order, at the date or dates fixed by the Trustee and, in case of the 
distribution of such money on account of principal (or premium, if any) or 
interest, upon presentation of the Securities and the notation thereon of the 
payment if only partially paid and upon surrender thereof if fully paid:

          FIRST:  To the payment of all amounts due the Trustee under 
     Section 7.07;

          SECOND:  To the payment of the amounts then due and unpaid for first,
     interest on, and, second, for principal of (and premium, if any, on) the 
     Securities in respect of which or for the benefit of which such money has 
     been collected, ratably, without preference or priority of any kind, 
     according to the amounts due and payable on such Securities for interest 
     and principal (and premium, if any) respectively; and

          THIRD:  The balance, if any, to the Person or Persons entitled 
     thereto, as their interest may appear or as a court of competent 
     jurisdiction shall direct.

     SECTION 6.07.  LIMITATION ON SUITS.  No Holder of any Security shall 
have any right to institute any proceeding, judicial or otherwise, with 
respect to this Indenture, or for the appointment of a receiver or trustee, 
or for any other remedy hereunder, unless

          (1) such Holder has previously given written notice to the Trustee 
     of a continuing Event of Default;

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

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

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


                                      23

<PAGE>

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

     The foregoing limitations on the pursuit of remedies by a Securityholder 
shall not apply to a suit instituted by a Holder of Securities for the 
enforcement of payment of the principal of or interest on such Security on or 
after the applicable due date specified in such Security.  A Securityholder 
may not use this Indenture to prejudice the rights of another Securityholder 
or to obtain a preference or priority over another Securityholder.

     SECTION 6.08.  UNCONDITIONAL RIGHT OF HOLDERS TO RECEIVE PRINCIPAL, 
PREMIUM AND INTEREST.  Notwithstanding any other provision in this Indenture, 
the Holder of any Security shall have the right, which is absolute and 
unconditional, to receive payment of the principal of (and premium, if any) 
and interest on such Security on the respective Stated Maturities expressed 
in such Security and to institute suit for the enforcement of any such 
payment, and such rights shall not be impaired without the consent of such 
Holder.

     SECTION 6.09.  RESTORATION OF RIGHTS AND REMEDIES.  If the Trustee or 
any Holder has instituted any proceeding to enforce any right or remedy under 
this Indenture and such proceeding has been discontinued or abandoned for any 
reason, or has been determined adversely to the Trustee or to such Holder, 
then and in every such case, subject to any determination in such proceeding, 
the Company, the Trustee and the Holders shall be restored severally and 
respectively to their former positions hereunder and thereafter all rights 
and remedies of the Trustee and the Holders shall continue as though no such 
proceeding had been instituted.

     SECTION 6.10.  RIGHTS AND REMEDIES CUMULATIVE.  Except as otherwise 
provided with respect to the replacement or payment of mutilated, destroyed, 
lost or stolen Securities in the last paragraph of Section 2.07, no right or 
remedy herein conferred upon or reserved to the Trustee or to the Holders is 
intended to be exclusive of any other right or remedy, and every right and 
remedy shall, to the extent permitted by law, be cumulative and in addition 
to every other right and remedy given hereunder or now or hereafter existing 
at law or in equity or otherwise.  The assertion or employment of any right 
or remedy hereunder, or otherwise, shall not prevent the concurrent assertion 
or employment of any other appropriate right or remedy.

     SECTION 6.11.  DELAY OR OMISSION NOT WAIVER.  No delay or omission of 
the Trustee or of any Holder of any Securities to exercise any right or 
remedy accruing upon any Event of Default shall impair any such right or 
remedy or constitute a waiver of any such Event of Default or an acquiescence 
therein.  Every right and remedy given by this Article 6 or by law to the 
Trustee or to the Holders may be exercised from time to time, and as often as 
may be deemed expedient, by the Trustee or by the Holders, as the case may be.

     SECTION 6.12.  CONTROL BY HOLDERS.  The Holders of a majority in 
principal amount of the Securities may direct the time, method and place of 
conducting any proceeding for any remedy 


                                      24

<PAGE>

available to the Trustee or of exercising any trust or power conferred on the 
Trustee.  However, the Trustee may refuse to follow any direction that 
conflicts with law or this Indenture or, subject to Section 7.01, that the 
Trustee or its counsel determines is unduly prejudicial to the rights of 
other Securityholders or would involve the Trustee in personal liability; 
provided, however, that the Trustee may take any other action deemed proper 
by the Trustee that is not inconsistent with such direction.  Prior to taking 
any action hereunder, the Trustee shall be entitled to indemnification 
satisfactory to it by such requesting Holders in its sole discretion against 
all losses and expenses caused by taking or not taking such action.

     SECTION 6.13.  WAIVER OF PAST DEFAULTS.  The Holders of not less than a 
majority in principal amount of the outstanding Securities may on behalf of 
the Holders of all the Securities waive any past default hereunder and its 
consequences, except a default

          (1) in the payment of the principal of (or premium, if any) or 
     interest on any Security, or

          (2) in respect of a covenant or provision hereof which under Article 9
     cannot be modified or amended without the consent of the Holder of each 
     Outstanding Security affected.

     Upon any such waiver, such default shall cease to exist, and any Event 
of Default arising therefrom shall be deemed to have been cured, for every 
purpose of this Indenture; but no such waiver shall extend to any subsequent 
or other default or impair any right consequent thereon.

     SECTION 6.14.  UNDERTAKING FOR COSTS.  In any suit for the enforcement 
of any right or remedy under this Indenture, or in any suit against the 
Trustee for any action taken, suffered or omitted by it as Trustee, a court 
may require any party litigant in such suit to file an undertaking to pay the 
costs of such suit, and may assess costs against any such party litigant, 
having due regard to the merits and good faith of the claims or defenses made 
by such party litigant.

     SECTION 6.15.  WAIVER OF USURY, STAY OR EXTENSION LAWS.  The Company 
covenants (to the extent that it may lawfully do so) that it will not at any 
time insist upon, or plead, or in any manner whatsoever claim or take the 
benefit or advantage of, any usury, stay or extension law wherever enacted, 
now or at any time hereafter in force, which may affect the covenants or the 
performance of this Indenture; and the Company (to the extent that it may 
lawfully do so) hereby expressly waives all benefit or advantage of any such 
law and covenants that it will not hinder, delay or impede the execution of 
any power herein granted to the Trustee, but will suffer and permit the 
execution of every such power as though no such law had been enacted.

                                 ARTICLE 7

                                  TRUSTEE

     SECTION 7.01.  DUTIES OF TRUSTEE.  

          (a) If an Event of Default has occurred and is continuing, the Trustee
     shall exercise the rights and powers vested in it by this Indenture and use
     the same degree of care and skill in their exercise as a prudent Person 
     would exercise or use under the circumstances in the conduct of such 
     Person's own affairs.

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

               (1) the Trustee undertakes to perform such duties and only such
          duties as are specifically set forth in this Indenture and no implied
          covenants or obligations shall be read into this Indenture against the
          Trustee; and

               (2) in the absence of bad faith on its part, the Trustee may 
          conclusively rely, as to the truth of the statements and the 
          correctness of the opinions expressed therein, upon certificates or 
          opinions furnished to the Trustee and conforming to the requirements
          of this Indenture.  However, the Trustee or its counsel shall examine
          the certificates and opinions to determine whether or not they conform
          to the requirements of this Indenture.

          (c)  The Trustee may not be relieved from liability for its own 
     negligent action, its own negligent failure to act or its own wilful 
     misconduct, except that:

               (1) this paragraph does not limit the effect of paragraph (b) of
          this Section;

               (2) the Trustee shall not be liable for any error of judgment 
          made in good faith by a Trust Officer or by a Trust Officer upon 
          advice of counsel unless it is proved that the Trustee was negligent
          in ascertaining the pertinent facts; and

               (3) the Trustee shall not be liable with respect to any action 
          it takes or omits to take in good faith in accordance with a direction
          received by it pursuant to Section 6.12.

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

          (e)  The Trustee shall not be liable for interest on any money 
     received by it except as the Trustee may agree in writing with the Company.


                                      26

<PAGE>

          (f)  Money held in trust by the Trustee need not be segregated from 
     other funds except to the extent required by law.

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

          (h)  Every provision of this Indenture relating to the conduct or 
     affecting the liability of or affording protection to the Trustee shall 
     be subject to the provisions of this Section and to the provisions of 
     the TIA.

     SECTION 7.02.  RIGHTS OF TRUSTEE. 

          (a) The Trustee may rely on any document believed by it to be genuine
     and to have been signed or presented by the proper person.  The Trustee 
     need not investigate any fact or matter stated in the document.

          (b) Before the Trustee acts or refrains from acting, it may require an
     Officers' Certificate or an Opinion of Counsel.  The Trustee shall not be 
     liable for any action it takes or omits to take in good faith in reliance 
     on any such Officers' Certificate or Opinion of Counsel.

          (c) The Trustee may act through agents and shall not be responsible 
     for the misconduct or negligence of any agent appointed with due care.

          (d) The Trustee shall not be liable for any action it takes or omits 
     to take in good faith which it believes to be authorized or within its 
     rights or powers; PROVIDED, HOWEVER, that the Trustee's conduct does not
     constitute wilful misconduct or negligence.

          (e) The Trustee may consult with counsel, and the advice or opinion of
     counsel with respect to legal matters relating to this Indenture and the 
     Securities shall be full and complete authorization and protection from 
     liability in respect to any action taken, omitted or suffered by it 
     hereunder in good faith and in accordance with the advice or opinion of 
     such counsel.

          (f) Except with respect to Section 4.01, the Trustee shall have no 
     duty to inquire as to the performance of the Issuer's covenants in 
     Article 4.  In addition, the Trustee shall not be deemed to have knowledge
     of any Default or Event of Default except (i) any Event of Default 
     occurring pursuant to Sections 6.01(1), 6.01(2) and 4.01 (excluding the
     nonpayment of special interest relating to a Registration Default), or 
     (ii) any Default or Event of Default of which the Trustee shall have 
     received written notification or obtained actual knowledge.


                                      27

<PAGE>

     SECTION 7.03.  INDIVIDUAL RIGHTS OF TRUSTEE.  The Trustee in its 
individual or any other capacity may become the owner or pledgee of 
Securities and may otherwise deal with the Company or its Affiliates with the 
same rights it would have if it were not Trustee.  Any Paying Agent, 
Registrar, co-registrar or co-paying agent may do the same with like rights.  
However, the Trustee must comply with Sections 7.10 and 7.11.

     SECTION 7.04.  TRUSTEE'S DISCLAIMER.  The Trustee shall not be 
responsible for and makes no representation as to the validity or adequacy of 
this Indenture or the Securities, it shall not be accountable for the 
Company's use of the proceeds from the Securities, and it shall not be 
responsible for any statement of the Company in the Indenture or in any 
document issued in connection with the sale of the Securities or in the 
Securities other than the Trustee's certificate of authentication.

     SECTION 7.05.  NOTICE OF DEFAULTS.  If a Default occurs and is 
continuing and if it is known to the Trustee, the Trustee shall mail to each 
Securityholder notice of the Default within 90 days after it occurs.  Except 
in the case of a Default in payment of principal of or interest on any 
Security (including payments pursuant to the mandatory redemption provisions 
of such Security, if any), the Trustee may withhold the notice if and so long 
as a committee of its Trust Officers in good faith determines that 
withholding the notice is in the interests of Securityholders.

     SECTION 7.06.  REPORTS BY TRUSTEE TO HOLDERS.  As promptly as 
practicable after each May 15 beginning with the May 15 following the date of 
this Indenture, and in any event prior to June 15 in each year, the Trustee 
shall mail to each Securityholder a brief report dated as of May 15 that 
complies with TIA Section 313(a).  The Trustee also shall comply with TIA 
Section 313(b).

     A copy of each report at the time of its mailing to Securityholders 
shall be filed with the SEC and each stock exchange (if any) on which the 
Securities are listed.  The Company agrees to notify promptly the Trustee 
whenever the Securities become listed on any stock exchange and of any 
delisting thereof.

     SECTION 7.07.  COMPENSATION AND INDEMNITY.  The Company shall pay to the 
Trustee from time to time reasonable compensation for its services as 
Trustee, Registrar, Paying Agent and any other function.  The Trustee's 
compensation shall not be limited by any law on compensation of a trustee of 
an express trust.  The Company shall reimburse the Trustee upon request for 
all reasonable out-of-pocket expenses incurred or made by it, including costs 
of collection, in addition to the compensation for its services.  Such 
expenses shall include the reasonable compensation and expenses, 
disbursements and advances of the Trustee's agents, counsel, accountants and 
experts.  The Company shall indemnify the Trustee against any and all loss, 
liability or expense (including attorneys' fees) incurred by it in connection 
with the administration of this Indenture and any related document and the 
performance of its duties thereunder.  The Trustee shall notify the Company 
promptly of any claim for which it may seek indemnity.  Failure by the 
Trustee to so notify the Company shall not relieve the Company of its 
obligations hereunder.  The Trustee may have separate counsel and the Company 
shall pay the fees and expenses of such counsel.  The Company need not 


                                      28

<PAGE>

reimburse any expense or indemnify against any loss, liability or expense 
incurred by the Trustee through the Trustee's own wilful misconduct, gross 
negligence or bad faith.

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

     The Company's payment obligations pursuant to this Section shall survive 
the discharge of this Indenture.  When the Trustee incurs expenses after the 
occurrence of a Default specified in Section 6.01(4) or (5) with respect to 
the Company, the expenses are intended to constitute expenses of 
administration under any applicable bankruptcy law.

     SECTION 7.08.  REPLACEMENT OF TRUSTEE.  The Trustee may resign at any 
time by so notifying the Company.  The Holders of a majority in principal 
amount of the Securities may remove the Trustee by so notifying the Trustee 
with 60 days advance notice and may appoint a successor Trustee.  The Company 
shall remove the Trustee if:

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

          (2) the Trustee is adjudged bankrupt or insolvent;

          (3) a receiver or other public officer takes charge of the Trustee or
     its property; or

          (4) the Trustee otherwise becomes incapable of acting.

     If the Trustee resigns, is removed by the Company or by the Holders of a 
majority in principal amount of the Securities and such Holders do not 
reasonably promptly appoint a successor Trustee, or if a vacancy exists in 
the office of Trustee for any reason (the Trustee in such event being 
referred to herein as the retiring Trustee), the Company shall promptly 
appoint a successor Trustee.

     A successor Trustee shall deliver a written acceptance of its 
appointment to the retiring Trustee and to the Company.  Thereupon the 
resignation or removal of the retiring Trustee shall become effective, and 
the successor Trustee shall have all the rights, powers and duties of the 
Trustee under this Indenture.  The successor Trustee shall mail a notice of 
its succession to Securityholders.  The retiring Trustee shall promptly 
transfer all property held by it as Trustee to the successor Trustee, subject 
to the lien provided for in Section 7.07.

     If a successor Trustee does not take office within 60 days after the 
retiring Trustee resigns or is removed, the retiring Trustee or the Holders 
of 10% in principal amount of the Securities may petition any court of 
competent jurisdiction for the appointment of a successor Trustee.

     If the Trustee fails to comply with Section 7.10, any Securityholder may 
petition any court of competent jurisdiction for the removal of the Trustee 
and the appointment of a successor Trustee.


                                      29

<PAGE>

     Notwithstanding the replacement of the Trustee pursuant to this Section, 
the Company's obligations under Section 7.07 shall continue for the benefit 
of the retiring Trustee.

     SECTION 7.09.  SUCCESSOR TRUSTEE BY MERGER.  If the Trustee consolidates 
with, merges or converts into, or transfers all or substantially all its 
corporate trust business or assets to, another corporation or banking 
association, the resulting, surviving or transferee corporation without any 
further act shall be the successor Trustee.

     In case at the time such successor or successors by merger, conversion 
or consolidation to the Trustee shall succeed to the trusts created by this 
Indenture any of the Securities shall have been authenticated but not 
delivered, any such successor to the Trustee may adopt the certificate of 
authentication of any predecessor trustee, and deliver such Securities so 
authenticated; and in case at that time any of the Securities shall not have 
been authenticated, any successor to the Trustee may authenticate such 
Securities either in the name of any predecessor hereunder or in the name of 
the successor to the Trustee; and in all such cases such certificates shall 
have the full force which it is anywhere in the Securities or in this 
Indenture provided that the certificate of the Trustee shall have. 

     SECTION 7.10.  ELIGIBILITY; DISQUALIFICATION.  The Trustee shall at all 
times satisfy the requirements of TIA Section 310(a).  The Trustee shall have a
combined capital and surplus of at least $50,000,000 as set forth in its most 
recent published annual report of condition.  The Trustee shall comply with 
TIA Section 310(b); PROVIDED, HOWEVER, that there shall be excluded from the 
operation of TIA Section 310(b)(1) any indenture or indentures under which other
securities or certificates of interest or participation in other securities 
of the Company are outstanding if the requirements for such exclusion set 
forth in TIA Section 310(b)(1) are met.

     SECTION 7.11.  PREFERENTIAL COLLECTION OF CLAIMS AGAINST COMPANY.  Upon 
this Indenture (or any amendment or supplement hereto) being qualified under 
the TIA, the Trustee shall comply with TIA Section 311(a), excluding any 
creditor relationship listed in TIA Section 311(b).  A Trustee who has 
resigned or been removed shall be subject to TIA Section 311(a) to the extent 
indicated.

                   DISCHARGE OF INDENTURE; DEFEASANCE

     SECTION 8.01.  DISCHARGE OF LIABILITY ON SECURITIES; DEFEASANCE.  (a) 
When (i) the Company delivers to the Trustee all outstanding Securities 
(other than Securities replaced pursuant to Section 2.07) for cancelation or 
(ii) all outstanding Securities have become due and payable, whether at 
maturity or as a result of the mailing of a notice of redemption pursuant to 
Article 3 hereof and the Company irrevocably deposits with the Trustee funds 
sufficient to pay at maturity or upon redemption all outstanding Securities, 
including interest thereon to maturity or such redemption date (other than 
Securities replaced pursuant to Section 2.07), and if in either case the 
Company pays all other sums payable hereunder by the Company, then this 
Indenture shall, subject to Section 8.01(c), cease to be of further effect.  
The Trustee shall acknowledge satisfaction and discharge of 


                                      30

<PAGE>

this Indenture on demand of the Company accompanied by an Officers' 
Certificate and an Opinion of Counsel and at the cost and expense of the 
Company.

          (b)  Subject to Sections 8.01(c) and 8.02, the Company at any time 
     may terminate (i) all its obligations under the Securities and this 
     Indenture ("legal defeasance option") or (ii) its obligations under 
     Sections 4.02, 4.06, 4.07 and 4.08, and the operation of Sections 6.01(3),
     6.01(4) and 6.01(5) (but, in the case of Sections 6.01(4) and 6.01(5), 
     with respect only to Significant Subsidiaries) ("covenant defeasance 
     option").  The Company may exercise its legal defeasance option 
     notwithstanding its prior exercise of its covenant defeasance option.

     If the Company exercises its legal defeasance option, payment of the 
Securities may not be accelerated because of an Event of Default with respect 
thereto.  If the Company exercises its covenant defeasance option, payment of 
the Securities may not be accelerated because of an Event of Default 
specified in Sections 6.01(3), 6.01(4) and 6.01(5) (but, in the case of 
Sections 6.01(4) and 6.01(5), with respect only to Significant Subsidiaries).

     Upon satisfaction of the conditions set forth herein and upon request of 
the Company, the Trustee shall acknowledge in writing the discharge of those 
obligations that the Company terminates.

          (c) Notwithstanding clauses (a) and (b) above, the Company's 
     obligations in Sections 2.03, 2.04, 2.05, 2.06, 2.07, 2.08, 7.07 and 7.08 
     and in this Article 8 shall survive until the Securities have been paid in
     full.  Thereafter, the Company's obligations in Sections 7.07, 8.04 and 
     8.05 shall survive.

     SECTION 8.02.  CONDITIONS TO DEFEASANCE.  The Company may exercise its 
legal defeasance option or its covenant defeasance option only if:

          (1) the Company irrevocably deposits in trust with the Trustee money
     or U.S. Government Obligations for the payment of principal of and interest
     on the Securities to maturity or redemption, as the case may be;

          (2) the Company delivers to the Trustee a certificate from a 
     nationally recognized firm of independent accountants expressing their 
     opinion that the payments of principal and interest when due and without
     reinvestment on the deposited U.S. Government Obligations plus any 
     deposited money without investment will provide cash at such times and in
     such amounts as will be sufficient to pay principal and interest when due
     on all the Securities to maturity or redemption, as the case may be;

          (3) 123 days pass after the deposit is made and during the 123-day 
     period no Default specified in Sections 6.01(4) or 6.01(5) with respect to
     the Company occurs which is continuing at the end of the period;


                                      31

<PAGE>

          (4) the deposit does not constitute a default under any other 
     agreement binding on the Company and is not prohibited by Article 10;

          (5) the Company delivers to the Trustee an Opinion of Counsel to the
     effect that the trust resulting from the deposit does not constitute, or 
     is qualified as, a regulated investment company under the Investment 
     Company Act of 1940; 

          (6) in the case of the legal defeasance option, the Company shall have
     delivered to the Trustee an Opinion of Counsel stating that (i) the Company
     has received from, or there has been published by, the Internal Revenue 
     Service a ruling, or (ii) since the date of this Indenture there has been 
     a change in the applicable Federal income tax law, in either case to the 
     effect that, and based thereon such Opinion of Counsel shall confirm that,
     the Securityholders will not recognize income, gain or loss for Federal 
     income tax purposes as a result of such defeasance and will be subject to
     Federal income tax on the same amounts, in the same manner and at the same
     times as would have been the case if such defeasance had not occurred;

          (7) in the case of the covenant defeasance option, the Company shall
     have delivered to the Trustee an Opinion of Counsel to the effect that the
     Securityholders will not recognize income, gain or loss for Federal income
     tax purposes as a result of such covenant defeasance and will be subject 
     to Federal income tax on the same amounts, in the same manner and at the 
     same times as would have been the case if such covenant defeasance had not
     occurred; and

          (8) the Company delivers to the Trustee an Officers' Certificate and 
     an Opinion of Counsel, each stating that all conditions precedent to the 
     defeasance and discharge of the Securities as contemplated by this 
     Article 8 have been complied with.

     Before or after a deposit, the Company may make arrangements satisfactory
to the Trustee for the redemption of Securities at a future date in accordance
with Article 3.

     SECTION 8.03.  APPLICATION OF TRUST MONEY.  The Trustee shall hold in 
trust money or U.S. Government Obligations deposited with it pursuant to this 
Article 8.  It shall apply the deposited money and the money from U.S. 
Government Obligations through the Paying Agent and in accordance with this 
Indenture to the payment of principal of and interest on the Securities.

     SECTION 8.04.  REPAYMENT TO COMPANY.  The Trustee and the Paying Agent 
shall promptly turn over to the Company upon request any excess money or 
securities held by them at any time.

     Subject to any applicable abandoned property law, the Trustee and the 
Paying Agent shall pay to the Company upon request any money held by them for 
the payment of principal or interest that remains unclaimed for two years, 
and, thereafter, Securityholders entitled to the money must look to the 
Company for payment as general creditors.

<PAGE>

     SECTION 8.05.  INDEMNITY FOR GOVERNMENT OBLIGATIONS.  The Company shall 
pay and shall indemnify the Trustee against any tax, fee or other charge 
imposed on or assessed against deposited U.S. Government Obligations or the 
principal and interest received on such U.S. Government Obligations.

     SECTION 8.06.  REINSTATEMENT.  If the Trustee or Paying Agent is unable 
to apply any money or U.S. Government Obligations in accordance with this 
Article 8 by reason of any legal proceeding or by reason of any order or 
judgment of any court or governmental authority enjoining, restraining or 
otherwise prohibiting such application, the Company's obligations under this 
Indenture and the Securities shall be revived and reinstated as though no 
deposit had occurred pursuant to this Article 8 until such time as the 
Trustee or Paying Agent is permitted to apply all such money or U.S. 
Government Obligations in accordance with this Article 8; PROVIDED, HOWEVER, 
that, if the Company has made any payment of interest on or principal of any 
Securities because of the reinstatement of its obligations, the Company shall 
be subrogated to the rights of the Holders of such Securities to receive such 
payment from the money or U.S. Government Obligations held by the Trustee or 
Paying Agent.

                                  ARTICLE 9

                                 AMENDMENTS

     SECTION 9.01.  WITHOUT CONSENT OF HOLDERS.  The Company and the Trustee 
may amend this Indenture or the Securities without notice to or consent of 
any Securityholder:

          (1) to cure any ambiguity, omission, defect or inconsistency;

          (2) to comply with Article 5;

          (3) to provide for uncertificated Securities in addition to or in 
     place of certificated Securities; PROVIDED, HOWEVER, that the 
     uncertificated Securities are issued in registered form for purposes of 
     Section 163(f) of the Code or in a manner such that the uncertificated 
     Securities are described in Section 163(f)(2)(B) of the Code;

         (4) to add guarantees with respect to the Securities, or to secure the
     Securities; 

          (5) to add to the covenants of the Company for the benefit of the 
     Holders or to surrender any right or power herein conferred upon the 
     Company;

          (6) to comply with any requirements of the SEC in connection with 
     qualifying, or maintaining the qualification of, this Indenture under the 
     TIA; or 

          (7) to make any change that does not adversely affect the rights of 
     any Securityholder. 


                                      33

<PAGE>

     After an amendment under this Section becomes effective, the Company 
shall mail to Securityholders, with a copy to the Trustee, a notice briefly 
describing such amendment.  The failure to give such notice to all 
Securityholders, or any defect therein, shall not impair or affect the 
validity of an amendment under this Section.

     SECTION 9.02.  WITH CONSENT OF HOLDERS.  The Company and the Trustee may 
amend this Indenture or the Securities without notice to any Securityholder 
but with the written consent of the Holders of at least a majority in 
principal amount of the Securities then outstanding (including consents 
obtained in connection with a tender offer or exchange for the Securities).  
However, without the consent of each Securityholder affected thereby, an 
amendment may not:

          (1) reduce the amount of Securities whose Holders must consent to an
     amendment;

          (2) reduce the rate of or extend the time for payment of interest on
     any Security;

          (3) reduce the principal of or extend the Stated Maturity of any 
     Security;

          (4) reduce the premium payable upon the redemption of any Security or
     change the time at which any Security may be redeemed in accordance with 
     Article 3;

          (5) make any Security payable in money other than that stated in the
     Security; 

          (6) make any change in Section 6.08 or 6.13 or the second sentence of
     this Section;

          (7) impair the right of any Holder to institute suit for enforcement 
     of any payment on or with respect to such Holder's Securities; or

          (8) impair the right of any Holder to receive payment of interest on
     and principal of such Holder's Securities on or after the due dates 
     therefor.

     It shall not be necessary for the consent of the Holders under this 
Section to approve the particular form of any proposed amendment, but it 
shall be sufficient if such consent approves the substance thereof.

     After an amendment under this Section becomes effective, the Company 
shall mail to Securityholders, with a copy to the Trustee, a notice briefly 
describing such amendment.  The failure to give such notice to all 
Securityholders, or any defect therein, shall not impair or affect the 
validity of an amendment under this Section.

     SECTION 9.03.  COMPLIANCE WITH TRUST INDENTURE ACT.  Every amendment to 
this Indenture or the Securities shall comply with the TIA as then in effect.

<PAGE>

     SECTION 9.04.  REVOCATION AND EFFECT OF CONSENTS AND WAIVERS.  A consent 
to an amendment or a waiver by a Holder of a Security shall bind the Holder 
and every subsequent Holder of that Security or portion of the Security that 
evidences the same debt as the consenting Holder's Security, even if notation 
of the consent or waiver is not made on the Security.  However, any such 
Holder or subsequent Holder may revoke the consent or waiver as to such 
Holder's Security or portion of the Security if the Trustee receives the 
notice of revocation before the date the amendment or waiver becomes 
effective.  After an amendment or waiver becomes effective, it shall bind 
every Securityholder.  An amendment or waiver becomes effective upon the 
execution of such amendment or waiver by the Trustee.

     The Company may, but shall not be obligated to, fix a record date for 
the purpose of determining the Securityholders entitled to give their consent 
or take any other action described above or required or permitted to be taken 
pursuant to this Indenture.  If a record date is fixed, then notwithstanding 
the immediately preceding paragraph, those Persons who were Securityholders 
at such record date (or their duly designated proxies), and only those 
Persons, shall be entitled to give such consent or to revoke any consent 
previously given or to take any such action, whether or not such Persons 
continue to be Holders after such record date.  No such consent shall be 
valid or effective for more than 120 days after such record date.

     SECTION 9.05.  NOTATION ON OR EXCHANGE OF SECURITIES.  If an amendment 
changes the terms of a Security, the Trustee may require the Holder of the 
Security to deliver it to the Trustee.  The Trustee may place an appropriate 
notation on the Security regarding the changed terms and return it to the 
Holder.  Alternatively, if the Company or the Trustee so determines, the 
Company in exchange for the Security shall issue and the Trustee shall 
authenticate a new Security that reflects the changed terms.  Failure to make 
the appropriate notation or to issue a new Security shall not affect the 
validity of such amendment.

     SECTION 9.06.  TRUSTEE TO SIGN AMENDMENTS.  The Trustee shall sign any 
amendment authorized pursuant to this Article 9 if the amendment does not 
adversely affect the rights, duties, liabilities or immunities of the 
Trustee.  If it does, the Trustee may but need not sign it.  In signing such 
amendment the Trustee shall be entitled to receive indemnity reasonably 
satisfactory to it and to receive, and (subject to Section 7.01) shall be 
fully protected in relying upon, an Officers' Certificate and an Opinion of 
Counsel stating that such amendment is authorized or permitted by this 
Indenture.

     SECTION 9.07.  PAYMENT FOR CONSENT.  Neither the Company nor any 
Affiliate of the Company shall, directly or indirectly, pay or cause to be 
paid any consideration, whether by way of interest, fee or otherwise, to any 
Holder for or as an inducement to any consent, waiver or amendment of any of 
the terms or provisions of this Indenture or the Securities unless such 
consideration is offered to be paid to all Holders that so consent, waive or 
agree to amend in the time frame set forth in solicitation documents relating 
to such consent, waiver or agreement.

registration books of the Registrar and shall be sufficiently given if so 
mailed within the time prescribed.

     Failure to mail a notice or communication to a Securityholder or any

Securityholders.  If a notice or communication is mailed in the manner 
provided above, it is duly given, whether or not the addressee receives it.

     SECTION 10.03.  COMMUNICATION BY HOLDERS WITH OTHER HOLDERS.  
Securityholders may communicate pursuant to TIA Section 312(b) with other

Upon any request or application by the Company to the Trustee to take or 
refrain from taking any action under this Indenture, the Company shall

     investigation upon which the statements or opinions contained in such 
     certificate or opinion are based;

          (3) a statement that, in the opinion of such individual, he has made
     such examination or investigation as is necessary to enable him to express
     an informed opinion as to whether or not such covenant or condition has

     SECTION 10.06.  WHEN SECURITIES DISREGARDED.  In determining whether the 
Holders of the required principal amount of Securities have concurred in any 
direction, waiver or consent, Securities owned by the Company or by any 
Person directly or indirectly controlling or controlled by or under direct or 
indirect common control with the Company shall be disregarded and deemed not 
to be outstanding, except that, for the purpose of determining whether the 
Trustee shall be protected in relying on any such direction, waiver or 
consent, only Securities which the Trustee knows are so owned shall be so 
disregarded.  Also, subject to the foregoing, only Securities outstanding at 
the time shall be considered in any such determination.

     SECTION 10.07.  RULES BY TRUSTEE, PAYING AGENT AND REGISTRAR.  The 
Trustee may make reasonable rules for action by or a meeting of 
Securityholders.  The Registrar and the Paying Agent may make reasonable 
rules for their functions.

     SECTION 10.08.  LEGAL HOLIDAYS.  A "Legal Holiday" is a Saturday, a 
Sunday or a day on which banking institutions are not required to be open in 
the State of Illinois.  If a payment date is a Legal Holiday, payment shall 
be made on the next succeeding day that is not a Legal Holiday, and no 
interest shall accrue for the intervening period.  If a regular record date 
is a Legal Holiday, the record date shall not be affected.

     SECTION 10.09.  GOVERNING LAW.  This Indenture and the Securities shall 
be governed by, and construed in accordance with, the laws of the State of 
New York but without giving effect to applicable principles of conflicts of

would be required thereby.

     SECTION 10.10.  NO RECOURSE AGAINST OTHERS.  A director, officer, 
employee or stockholder, as such, of the Company shall not have any liability 
for any obligations of the Company under the Securities or this Indenture or 
for any claim based on, in respect of or by reason of such obligations or 
their creation.  By accepting a Security, each Securityholder shall waive and 
release all such liability.  The waiver and release shall be part of the 
consideration for the issue of the Securities.

     SECTION 10.11.  SUCCESSORS.  All agreements of the Company in this 
Indenture and the Securities shall bind its successors.  All agreements of 
the Trustee in this Indenture shall bind its successors.

     SECTION 10.12.  MULTIPLE ORIGINALS.  The parties may sign any number of 
copies of this Indenture.  Each signed copy shall be an original, but all of 
them together represent the same agreement.  One signed copy is enough to

     2.   THE SECURITIES.

     2.1  FORM AND DATING.

     The Initial Securities are being offered and sold by the Company 
pursuant to the Purchase Agreement.  The Initial Securities will be resold, 
initially only to QIBs in reliance on Rule 144A under the Securities Act 
("Rule 144A"), and in reliance on Regulation S under the Securities Act 
("Regulation S").  Initial Securities may thereafter be transferred to, among 
others, QIBs, purchasers in reliance on Regulation S and IAIs.   

          (a) GLOBAL SECURITIES.  Initial Securities shall be issued initially
     in the form of one or more permanent global Securities in definitive, fully
     registered form without interest coupons with the global securities legend
     and restricted securities legend set forth in Exhibit 1 hereto (each, a 
     "Global Security"), which shall be deposited on behalf of the purchasers 
     of the Initial Securities represented thereby with the Trustee, at its 
     Chicago, Illinois office, as custodian for the Depository (or with such 
     other custodian as the Depository may direct), and registered in the name 
     of the Depository or a nominee of the Depository, duly executed by the 
     Company and authenticated by the Trustee as hereinafter provided.  The 
     aggregate principal amount of the Global Securities may from time to time
     be increased or decreased by adjustments made on the records of the 
     Trustee and the Depository or its nominee as hereinafter provided.

          (b) BOOK-ENTRY PROVISIONS.  This Section 2.1(b) shall apply only to a
     Global Security deposited with or on behalf of the Depository.

          The Company shall execute and the Trustee shall, in accordance with 
     this Section 2.1(b) and pursuant to an order from the Company, authenticate
     and deliver initially one or more Global Securities that (a) shall be 
     registered in the name of the Depository for such Global Security or Global
     Securities or the nominee of such Depository and (b) shall be delivered by
     the Trustee to such Depository or pursuant to such Depository's 
     instructions or held by the Trustee as custodian for the Depository.

          Members of, or participants in, the Depository ("Agent Members") shall
     have no rights under this Indenture with respect to any Global Security 
     held on their behalf by the Depository or by the Trustee as the Securities
     Custodian or under such Global Security, and the Depository may be treated
     by the Company, the Trustee and any agent of the Company or the Trustee as
     the absolute owner of such Global Security for all purposes whatsoever.  
     Notwithstanding the foregoing, nothing herein shall prevent the Company, 
     the Trustee or any agent of the Company or the Trustee from giving effect
     to any written certification, proxy or other authorization furnished by 
     the Depository or impair, as between the Depository and its Agent Members,
     the operation of customary practices of such Depository governing the 
     exercise of the rights of a holder of a beneficial interest in any Global
     Security.

Initial Securities for original issue in an aggregate principal amount of 
$200,000,000 and (2) Exchange Securities or Private Exchange Securities for 
issue only in a Registered Exchange Offer or a Private Exchange, 
respectively, as directed pursuant to the Registration Agreement, for a like 
principal amount of Initial Securities, in each case upon a written order of 
the Company signed by two Officers or by an Officer and either an Assistant 
Treasurer or an Assistant Secretary of the Company.  Such order shall specify 
the amount of the Securities to be authenticated and the date on which the 
original issue of Securities is to be authenticated and whether the 
Securities are to be Initial Securities, Exchange Securities or Private 
Exchange Securities.  The aggregate principal amount of Securities 
outstanding at any time may not exceed $200,000,000 except as provided in 
Section 2.07 of this Indenture.

     2.3  TRANSFER AND EXCHANGE.

     (a) TRANSFER AND EXCHANGE OF DEFINITIVE SECURITIES.  When Definitive 
Securities are presented to the Registrar or a co-registrar with a request:

          (x) to register the transfer of such Definitive Securities; or

          (y) to exchange such Definitive Securities for an equal principal 
     amount of Definitive Securities of other authorized denominations,

the Registrar or co-registrar shall register the transfer or make the 
exchange as requested if its reasonable requirements for such transaction are 
met; PROVIDED, HOWEVER, that the Definitive Securities surrendered for 
transfer or exchange:

          (i)  shall be duly endorsed or accompanied by a written instrument of
     transfer in form reasonably satisfactory to the Company and the Registrar 
     or co-registrar, duly executed by the Holder thereof or his attorney duly

     or pursuant to clause (A), (B) or (C) below, and are accompanied by the 
     following additional information and documents, as applicable:

               (A) if such Definitive Securities are being delivered to the 
          Registrar by a Holder for registration in the name of such Holder, 
          without transfer, a certification from such Holder to that effect 
          (in the form set forth on the reverse of the Security); or

          Company, a certification to that effect (in the form set forth on the
          reverse of the Security); or

               (C) if such Definitive Securities are being transferred (w) 
          pursuant to an exemption from registration in accordance with   
          Rule 144; or (x) in reliance on another exemption from the 
          registration requirements of the Securities Act: (i) a certification

          counsel or other evidence reasonably satisfactory to them as to the 
          compliance with the restrictions set forth in the legend set forth in
          Section 2.3(d)(i).

     (b)  RESTRICTIONS ON TRANSFER OF A DEFINITIVE SECURITY FOR A BENEFICIAL 
INTEREST IN A GLOBAL SECURITY.  A Definitive Security may not be exchanged 
for a beneficial interest in a Global Security except upon satisfaction of 
the requirements set forth below.  Upon receipt by the Trustee of a 
Definitive Security, duly endorsed or accompanied by appropriate instruments 
of transfer, in form satisfactory to the Trustee, together with:

          (i) certification, in the form set forth on the reverse of the 
     Security, that such Definitive Security is being transferred (A) to a 
     QIB in accordance with Rule 144A, (B) to an IAI that has furnished to 
     the Trustee a signed letter containing certain representations and 
     agreements (the form of which letter can be obtained from the Trustee) 
     or (C) outside the United States in an offshore transaction within the 
     meaning of Regulation S and in compliance with Rule 904 under the 
     Securities Act; and

          (ii) written instructions directing the Trustee to make, or to direct 
     the Securities Custodian to make, an adjustment on its books and records 
     with respect to such Global Security to reflect an increase in the 
     aggregate principal amount of the Securities represented by the Global 
     Security, such instructions to contain information regarding the Depositary
     account to be credited with such increase, then the Trustee shall cancel 
     such Definitive Security and cause, or direct the Securities Custodian to
     cause, in accordance with the standing instructions and procedures existing
     between the Depository and the Securities Custodian, the aggregate 
     principal amount of Securities represented by the Global Security to be 
     increased by the aggregate principal amount of the Definitive Security to 
     be exchanged and shall credit or cause to be credited to the account 
     of the Person specified in such instructions a beneficial interest in the 
     Global Security equal to the principal amount of the Definitive Security so
     canceled.  If no Global Securities are then outstanding, the Company shall
     issue and the Trustee shall authenticate, upon written order of the Company
     in the form of an Officers' Certificate, a new Global Security in the 
     appropriate principal amount.

     (c)  TRANSFER AND EXCHANGE OF GLOBAL SECURITIES.  (i)  The transfer and 
exchange of Global Securities or beneficial interests therein shall be 
effected through the Depository, in accordance with this Indenture (including 
applicable restrictions on transfer set forth herein, if any) and the 
procedures of the 


                                     A-5

<PAGE>

Depository therefor.  A transferor of a beneficial interest in a Global 
Security shall deliver a written order given in accordance with the 
Depositary's procedures containing information regarding the participant 
account of the Depositary to be credited with a beneficial interest in the 
Global Security and such account shall be credited in accordance with such 
instructions with a beneficial interest in the Global Security and the 
account of the Person making the transfer shall be debited by an amount equal 
to the beneficial interest in the Global Security being transferred.  In the 
case of a transfer of a beneficial interest in a Global Security to an IAI, 
the transferee must furnish a signed letter to the Trustee containing certain 
representations and agreements (the form of which letter can be obtained from 
the Trustee).

          (ii)  If the proposed transfer is a transfer of a beneficial interest
     in one Global Security to a beneficial interest in another Global Security,
     the Registrar shall reflect on its books and records the date and an 
     increase in the principal amount of the Global Security to which such 
     interest is being transferred in an amount equal to the principal amount 
     of the interest to be so transferred, and the Registrar shall reflect on 
     its books and records the date and a corresponding decrease in the 
     principal amount of Global Security from which such interest is being 
     transferred.

          (iii) Notwithstanding any other provisions of this Appendix (other 
     than the provisions set forth in Section 2.4), a Global Security may not be
     transferred except as a whole by the Depository to a nominee of the 
     Depository or by a nominee of the Depository to the Depository or another
     nominee of the Depository or by the Depository or any such nominee to a 
     successor Depository or a nominee of such successor Depository.

          (iv)  In the event that a Global Security or any portion thereof is 
     exchanged for Securities in definitive registered form pursuant to Section
     2.4 or Section 2.09 of the Indenture, prior to the consummation of a 
     Registered Exchange Offer or the effectiveness of a Shelf Registration 
     Statement with respect to such Securities, such Securities may be exchanged
     only in accordance with such procedures as are substantially consistent 
     with the provisions of this Section 2.3 (including the certification 
     requirements set forth on the reverse of the Initial Securities intended 
     to ensure that such transfers comply with Rule 144A or Regulation S, as 
     the case may be) and such other procedures as may from time to time be 
     adopted by the Company.

     (d)  LEGEND.

          (i) Except as permitted by the following paragraphs (ii), (iii) and 
     (iv), each Security certificate evidencing the Global Securities and the 
     Definitive Securities (and all Securities issued in exchange therefor or 
     in substitution thereof) shall bear a legend in substantially the following
     form:

          REGISTRAR AND TRANSFER AGENT SUCH CERTIFICATES AND OTHER INFORMATION
          AS SUCH TRANSFER AGENT MAY REASONABLY REQUIRE TO CONFIRM THAT THE 
          TRANSFER COMPLIES WITH THE FOREGOING RESTRICTIONS."

          (ii) Upon any sale or transfer of a Transfer Restricted Security 
     (including any Transfer Restricted Security represented by a Global 
     Security) pursuant to Rule 144 under the Securities Act:

               (A) in the case of any Transfer Restricted Security that is a 
          Definitive Security, the Registrar shall permit the Holder thereof to
          exchange such Transfer Restricted Security for a Definitive Security

          Restricted Security, in either case,

     if the Holder certifies in writing to the Registrar that its request for 
     such exchange was made in reliance on Rule 144 (such certification to be 
     in the form set forth on the reverse of the Initial Security).

          (iii) After a transfer of any Initial Securities or Private Exchange 
     Securities during the period of the effectiveness of a Shelf Registration 
     Statement with respect to such Initial Securities or Private Exchange 
     Securities, as the case may be, all requirements pertaining to legends on
     such Initial Security or such Private Exchange Security will cease to 
     apply, the requirements requiring any such Initial Security or such 
     Private Exchange Security issued to certain Holders be issued in global
     form will cease to apply, and a certificated or global Initial Security 
     or Private Exchange Security without legends will be available to the 
     transferee of the Holder of such Initial Securities or Private Exchange 
     Securities upon exchange of such transferring Holder's certificated Initial
     Security or Private Exchange Security or directions to transfer such 
     Holder's interest in the Global Security, as applicable.

     to the Initial Securities pursuant to which Holders of such Initial 
     Securities are offered Exchange Securities in exchange for their Initial 
     Securities, all requirements pertaining to such Initial Securities that 
     Initial Securities issued to certain Holders be issued in global form will
     cease to apply and certificated Initial Securities with the restricted 
     securities legend set forth in Exhibit 1 hereto will be available to 
     Holders of such Initial Securities that do not exchange their Initial 
     Securities, and Exchange Securities in certificated or global form will
     be available to Holders that exchange such Initial Securities in such 
     Registered Exchange Offer.

     Initial Securities issued to certain Holders be issued in global form will
     still apply, and Private Exchange Securities in global form with the 
     Restricted Securities Legend set forth in Exhibit 1 hereto will be 
     available to Holders that exchange such Initial Securities in such Private
     Exchange.

          (vi) After the expiration of the "40-day restricted period" (within 
     the meaning of Rule 903(c)(3) of Regulation S), upon a sale or transfer of
     any Initial Security acquired pursuant to Regulation S, all requirements 
     pertaining to legends on such Initial Security will cease to apply, the 
     requirements requiring any such Initial Security be issued in global form
     will cease to apply, and an Initial Security in certificated or global 
     form without the Restricted Security Legend will be available to the 
     transferee of the Holder of such Initial Securities.

          (e)  CANCELATION OR ADJUSTMENT OF GLOBAL SECURITY.  At such time as 
all beneficial interests in a Global Security have either been exchanged for 
certificated or Definitive Securities, redeemed, repurchased or canceled, 
such Global Security shall be returned to the Depository for cancelation or 
retained and canceled by the Trustee.  At any time prior to such cancelation, 
if any beneficial interest in a Global Security is exchanged for certificated 
or Definitive Securities, redeemed, repurchased or canceled, the principal 
amount of Securities represented by such Global Security shall be reduced and 
an adjustment shall be made on the books and records of the Trustee (if it is 
then the Securities Custodian for such Global Security) with respect to such 
Global Security, by the Trustee or the Securities Custodian, to reflect such 
reduction.

          (f)  OBLIGATIONS WITH RESPECT TO TRANSFERS AND EXCHANGES OF

     payable upon exchange or transfer pursuant to Sections 3.06 and 9.05).

          (iii) The Registrar or co-registrar shall not be required to register

     15 Business Days before the mailing of a notice of an offer to repurchase 
     or redeem Securities or 15 Business Days before an interest payment date.

          (iv)  Prior to the due presentation for registration of transfer of 
     any Security, the Company, the Trustee, the Paying Agent, the Registrar or
     any co-registrar may deem and treat the person in whose name a Security is
     registered as the absolute owner of such Security for the purpose of 
     receiving payment of principal of and interest on such Security and for 
     all other purposes whatsoever, whether or not such Security is overdue, 
     and none of the Company, the Trustee, the Paying Agent, the Registrar or
     any co-registrar shall be affected by notice to the contrary.

          (v)   All Securities issued upon any transfer or exchange pursuant to
     the terms of this Indenture shall evidence the same debt and shall be 
     entitled to the same benefits under this Indenture as the Securities 
     surrendered upon such transfer or exchange.

         (g)    NO OBLIGATION OF THE TRUSTEE.

          (i)   The Trustee shall have no responsibility or obligation to any 
     beneficial owner of a Global Security, a member of, or a participant in 
     the Depository or other Person with respect to the accuracy of the records
     of the Depository or its nominee or of any participant or member thereof,
     with respect to any ownership interest in the Securities or with respect
     to the delivery to any participant, member, beneficial owner or other 
     Person (other than the Depository) of any notice (including any notice of
     redemption) or the payment of any amount, under or with respect to such 
     Securities.  All notices and communications to be given to the Holders 
     and all payments to be made to Holders under the Securities shall be given
     or made only to or upon the order of the registered Holders (which shall 
     be the Depository or its nominee in the case of a Global Security).  The 
     rights of beneficial owners in any Global Security shall be exercised 
     only through the Depository subject to the applicable rules and procedures
     of the Depository.  The Trustee may rely and shall be fully protected in 
     relying upon information furnished by the Depository with respect to its 
     members, participants and any beneficial owners.

          (ii)  The Trustee shall have no obligation or duty to monitor, 
     determine or inquire as to compliance with any restrictions on transfer 
     imposed under this Indenture or under applicable law with respect to any
     transfer of any interest in any Security (including any transfers 
     between or among Depository participants, members or beneficial owners 
     in any Global Security) other

     than to require delivery of such certificates and other documentation or
     evidence as are expressly required by, and to do so if and when expressly
     required by, the terms of this Indenture, and to examine the same to 
     determine substantial compliance as to form with the express requirements
     hereof.

     2.4  CERTIFICATED SECURITIES.

          (a) A Global Security deposited with the Depository or with the 
Trustee as custodian for the Depository pursuant to Section 2.1 shall be 
transferred to the beneficial owners thereof in the form of certificated 
Securities in an aggregate principal amount equal to the principal amount of 
such Global Security, in exchange for such Global Security, only if such 
transfer complies with Section 2.3 and (i) the Depository notifies the 
Company that it is unwilling or unable to continue as Depository for such 
Global Security or if at any time such Depository ceases to be a "clearing 
agency" registered under the Exchange Act and a successor depositary is not 
appointed by the Company within 90 days of such notice, or (ii) an Event of 
Default has occurred and is continuing or (iii) the Company, in its sole 
discretion, notifies the Trustee in writing that it elects to cause the 
issuance of certificated Securities under this Indenture.

          (b)  Any Global Security that is transferable to the beneficial 
owners thereof pursuant to this Section 2.4 shall be surrendered by the 
Depository to the Trustee to be so transferred, in whole or from time to time 
in part, without charge, and the Trustee shall authenticate and deliver, upon 
such transfer of each portion of such Global Security, an equal aggregate 
principal amount of certificated Initial Securities of authorized 
denominations.  Any portion of a Global Security transferred pursuant to this 
Section shall be executed, authenticated and delivered only in denominations 
of $1,000 and any integral multiple thereof and registered in such names as 
the Depository shall direct.  Any certificated Initial Security delivered in 
exchange for an interest in the Global Security shall, except as otherwise 
provided by Section 2.3(d), bear the restricted securities legend set forth 
in Exhibit 1 hereto.  

          (c)  Subject to the provisions of Section 2.4(b), the registered 
Holder of a Global Security may grant proxies and otherwise authorize any 
Person, including Agent Members and Persons that may hold interests through 
Agent Members, to take any action which a Holder is entitled to take under 
this Indenture or the Securities.

          (d)  In the event of the occurrence of either of the events 
specified in Section 2.4(a)(i), (ii) or (iii), the Company will promptly make 
available to the Trustee a reasonable supply of certificated Securities in 
definitive, fully registered form without interest coupons.

[FORM OF REVERSE SIDE OF INITIAL SECURITY]

6.875% Senior Note Due 2007

1.  Interest

    (a) LOUIS DREYFUS NATURAL GAS CORP., an Oklahoma corporation (such
corporation, and its successors and assigns under the Indenture hereinafter
referred to, being herein called the "Company"), promises to pay interest on
the principal amount of this Security at the rate per annum shown above;
provided, however, that if a Registration Default (as defined hereunder in
accordance with the Registration Agreement) occurs, additional interest will
accrue on this Security at a rate of 0.25% per annum from and including the
date on which any such Registration Default shall occur to but excluding the
date on which all Registration Defaults have been cured.  The Company will pay
interest semiannually on June 1 and December 1 of each year.  Interest on the
Securities will accrue from the most recent date to which interest has been
paid or, if no interest has been paid, from December 11, 1997.  Interest will
be computed on the basis of a 360-day year of twelve 30-day months.  The
Company shall pay interest on overdue principal at the rate borne by the
Securities plus 1% per annum, and it shall pay interest on overdue
installments of interest at the same rate to the extent lawful.

     (b) Special Interest.  The holder of this Security is entitled to the
benefits of a Registration Agreement, dated as of December 11, 1997, among the
Company and the Purchasers named therein (the "Registration Agreement").
Capitalized terms used in this paragraph (b) but not defined herein have the
meanings assigned to them in the Registration Agreement.  In the event that
(i) by the 150th day following the Issue Date, the Exchange Offer Registration
Statement is not filed with the Commission, (ii) by the 180th day following
the Issue Date, neither the Exchange Offer Registration Statement is declared
effective nor (if the Exchange Offer is not permitted as described above) the
Shelf Registration Statement is filed with the Commission, or (iii) by the
210th day following the Issue Date, the Exchange Offer is not consummated or
the Shelf Registration Statement is not declared effective with respect
thereto (each such event referred to in clauses (i) through (iii), a
"Registration Default"), interest will accrue on the applicable Securities (in
addition to stated interest on such Securities) which, except as provided
below, shall be the sole and exclusive remedy for such Registration Default
from and including the next day following each such Registration Default.  In
each case such additional interest (the "Special Interest") will be payable in
cash semiannually in arrears each June 1 and December 1, at a rate per annum
equal to 0.25% of the principal amount of such Securities for each such
Registration Default.  The aggregate amount of Special Interest payable
pursuant to the above provisions will in no event exceed 0.25% per annum of
the principal amount of such Securities which, except as provided below, shall
be the sole and exclusive remedy for such Registration Default.  Upon (a) the
filing of the Exchange Offer Registration Statement after the 150-day period
described in clause (i) above, (b) the effectiveness of the Exchange Offer
Registration Statement or the filing of the Shelf Registration

                                     Ex-1-5
<PAGE>

Statement after the 180-day period described in clause (ii) above or (c) the
consummation of the Exchange Offer for such Securities or the effectiveness of
a Shelf Registration Statement, as the case may be, after the 210-day period
described in clause (iii) above, the Special Interest payable on such
Securities as a result of the applicable Registration Default will cease to
accrue.  For purposes of the preceding sentence, the curing of a Registration
Default by the means described in clause (b) above shall constitute a cure of
the Registration Defaults described in clauses (i) and (ii) above, and the
curing of a Registration Default by the means described in clause (c) above
shall constitute a cure of the Registration Defaults described in clauses (i),
(ii) and (iii) above.  The Company will have no other liabilities for monetary
damages with respect to the above; provided, however, that in the event the
Company breaches, fails to comply with or violates certain provisions of the
Registration Agreement, the holders shall be entitled to, and the Company
shall not oppose the granting of, equitable relief, including injunction and
specific performance.

     In the event that a Shelf Registration Statement is declared effective
pursuant to the paragraph preceding the immediately preceding paragraph, if
the Company fails to keep such Registration Statement continuously effective
for the period required by the Registration Agreement (except as specifically
permitted therein), then from such time as the Shelf Registration Statement is
no longer effective until the earlier of (i) the date that the Shelf
Registration Statement is again deemed effective and (ii) the date that is the
earliest of (x) the second anniversary of the Issue Date (or until the first
anniversary of the effective date if the Shelf Registration Statement is filed
at the request of the Initial Purchasers), (y) the time when the Securities
registered thereunder can be sold by non-affiliates pursuant to Rule 144 under
the Securities Act without any limitation under classes (c), (e), (f) and (h)
of Rule 144, or (z) the date as of which all such Securities are sold pursuant
to the Shelf Registration Statement, Special Interest shall accrue at a rate
per annum equal to 0.25% of the principal amount of the Securities which,
except as provided below, shall be the sole and exclusive remedy for such
Registration Default and shall be payable in cash semiannually in arrears each
June 1 and December 1.  The Company will have no other liabilities for
monetary damages with respect to the above; provided, however, that in the
event the Company breaches, fails to comply with or violates certain
provisions of the Registration Agreement, the holders shall be entitled to,
and the Company shall not oppose the granting of, equitable relief, including
injunction and specific performance.

2.  Method of Payment

     The Company will pay interest on the Securities (except defaulted 
interest) to the Persons who are registered holders of Securities at the 
close of business on the May 15 or November 15 next preceding the interest 
payment date even if Securities are canceled after the record date and on or 
before the interest payment date.  Holders must surrender Securities to a 
Paying Agent to collect principal payments.  The Company will pay principal 
and interest in money of the United States that at the time of payment is 
legal tender for payment of public and private debts.  Payments in respect of 
the Securities represented by a Global Security (including principal, premium 
and interest) will be made by wire transfer of immediately available funds to 
the accounts specified by The Depository Trust Company.  The Company will 
make all payments in respect of a certificated Security (including principal, 
premium 

                                     Ex-1-6
<PAGE>

and interest) by mailing a check to the registered address of each
Holder thereof; provided, however, that payments on a certificated Security
will be made by wire transfer to a U.S. dollar account maintained by the payee
with a bank in the United States if such Holder elects payment by wire
transfer by giving written notice to the Trustee or the Paying Agent to such
effect designating such account no later than 30 days immediately preceding
the relevant due date for payment (or such other date as the Trustee may
accept in its discretion).

3.  Paying Agent and Registrar

     Initially, LaSalle National Bank ("Trustee"), will act as Paying Agent
and Registrar.  The Company may appoint and change any Paying Agent, Registrar
or co-registrar without notice.  The Company or any of its domestically
incorporated Wholly-Owned Subsidiaries may act as Paying Agent, Registrar or
co-registrar.

4.  Indenture

     The Company issued the Securities under an Indenture dated as of December
11, 1997 ("Indenture"), between the Company and the Trustee.  The terms of the
Securities include those stated in the Indenture and those made part of the
Indenture by reference to the Trust Indenture Act of 1939 (15 U.S.C. Sections
77aaa-77bbbb) as in effect on the date of the Indenture (the "Act").  Terms
defined in the Indenture and not defined herein have the meanings ascribed
thereto in the Indenture.  The Securities are subject to all such terms, and
Securityholders are referred to the Indenture and the Act for a statement of
those terms.

     The Securities are general unsecured obligations of the Company limited
to $200,000,000 aggregate principal amount (subject to Section 2.07 of the
Indenture).

     The Company will not, and will not permit any of its Subsidiaries to,
create, incur or otherwise cause or suffer to exist or become effective any
Liens of any kind upon any Principal Property or any shares of stock or
indebtedness of any Subsidiary that owns or leases any Principal Property
(whether such Principal Property, shares of stock or indebtedness are now
owned or hereafter acquired) unless all payments due under the Indenture and
the Securities are secured on an equal and ratable basis with the obligations
so secured until such time as such obligation is no longer secured by a Lien,
except for Permitted Liens.

     Neither the Company nor any Subsidiary will enter into any Sale and
Leaseback Transaction with respect to any Principal Property unless either (a)
the Company or such Subsidiary would be entitled, pursuant to the provisions
of the Indenture, to incur Indebtedness secured by a Lien on the property to
be leased without equally and ratably securing the Securities or (b) the
Company, within 180 days after the effective date of such transaction, applies
to the voluntary retirement of its funded debt an amount equal to the value of
such transaction, defined as the greater of the net proceeds of the sale of
the

                                     Ex-1-7
<PAGE>

property leased in such transaction or the fair value, in the opinion of the
Board of Directors, of the leased property at the time such transaction was
entered into.

    Notwithstanding the foregoing limitations on Liens and Sale and Leaseback
Transaction, the Company and its Subsidiaries may issue, assume, or guarantee
Indebtedness secured by a Lien without securing the Securities, or may enter
into Sale and Leaseback Transactions without retiring funded debt, or enter
into a combination of such transactions, if the sum of the principal amount of
all such Indebtedness and the aggregate value of all such Sale and Leaseback
Transactions does not at any time exceed 15% of the Consolidated Net Tangible
Assets of the Company.

5. Optional Redemption

     The Securities will be redeemable at any time, at the option of the
Company, in whole or from time to time in part, upon not less than 30 and not
more than 60 days' notice mailed to each Holder to be redeemed at the Holder's
address appearing in the books of the Registrar, on any date prior to maturity
(the "Redemption Date") at a price equal to 100% of the principal amount
thereof plus accrued interest to the Redemption Date (subject to the right of
Holders of record on the relevant record date to receive interest due on an
interest payment date that is on or prior to the Redemption Date) plus a
Make-Whole Premium, if any (the "Redemption Price").  In no event will the
Redemption Price ever be less than 100% of the principal amount of the
Securities plus accrued interest to the Redemption Date.

     The amount of the Make-Whole Premium with respect to any Security (or
portion thereof) to be redeemed will be equal to the excess, if any, of:

          (1) the sum of the present values, calculated as of the Redemption
     Date, of:

               (a)  each interest payment that, but for such redemption, would
          have been payable on the Security (or portion thereof) being redeemed
          on each interest payment date occurring after the Redemption Date
          (excluding any accrued interest for the period prior to the Redemption
          Date); and

               (b)  The principal amount that, but for such redemption, would
          have been payable at the final maturity of the Security (or portion
          thereof) being redeemed;

          over

          (2) the principal amount of the Security (or portion thereof) being
    redeemed.

     The present values of interest and principal payments referred to in clause
(i) above will be determined in accordance with generally accepted principles of
financial analysis.  Such present values will be calculated by discounting the
amount of each payment of interest or principal from the date that each such
payment would have been payable, but for the redemption, to the Redemption Date
at a

                                     Ex-1-8
<PAGE>

discount rate equal to the Treasury Yield (as defined below) plus 20 basis
points.  Copies of all such calculations and their resulting values will be
delivered to the Trustee (upon request to the Company) by the Company and shall
be attached to an Officers' Certificate.

     The Make-Whole Premium will be calculated by an independent investment
banking institution of national standing appointed by the Company; provided,
that if the Company fails to make such appointment at least 45 business days
prior to the Redemption Date, or if the institution so appointed is unwilling
or unable to make such calculation, such calculation will be made by Salomon
Brothers Inc or, if such firm is unwilling or unable to make such calculation,
by an independent investment banking institution of national standing
appointed by the Trustee (in any such case, an "Independent Investment
Banker").  Any fees incurred in connection with an Independent Investment
Banker shall be paid by the Company.

     For purposes of determining the Make-Whole Premium, "Treasury Yield"
means a rate of interest per annum equal to the weekly average yield to
maturity of United States Treasury Notes that have a constant maturity that
corresponds to the remaining term to maturity of the Securities, calculated to
the nearest 1/12th of a year (the "Remaining Term").  The Treasury Yield will
be determined as of the third business day immediately preceding the
applicable Redemption Date.

     The weekly average yields of United States Treasury Notes will be
determined by reference to the most recent statistical release published by
the Federal Reserve Bank of New York and designated "H.15(519) Selected
Interest Rates" or any successor release (the "H.15 Statistical Release").  If
the H.15 Statistical Release sets forth a weekly average yield for United
States Treasury Notes having a constant maturity that is the same as the
Remaining Term, then the Treasury Yield will be equal to such weekly average
yield.  In all other cases, the Treasury Yield will be calculated by
interpolation, on a straight-line basis, between the weekly average yields on
the United States Treasury Notes that have a constant maturity closest to and
greater than the Remaining Term and the United States Treasury Notes that have
a constant maturity closest to and less than the Remaining Term (in each case
as set forth in the H.15 Statistical Release).  Any weekly average yields so
calculated by interpolation will be rounded to the nearest 1/100th of 1%, with
any figure of 1/200th of 1% or above being rounded upward.  If weekly average
yields for United States Treasury Notes are not available in the H.15
Statistical Release or otherwise, then the Treasury Yield will be calculated
by interpolation of comparable rates selected by the Independent Investment
Banker.

     In the case of any partial redemption, selection of the Securities for
redemption will be made by the Trustee on a pro rata basis, by lot or by such
other method as the Trustee in its sole discretion shall deem to be fair and
appropriate, although no Security of $1,000 in original principal amount or
less shall be redeemed in part.  If any Security is to be redeemed in part
only, the notice of redemption relating to such Security shall state the
portion of the principal amount thereof to be redeemed.  A new Security in
principal amount equal to the unredeemed portion thereof will be issued in the
name of the Holder thereof upon cancelation of the original Security.

                                     Ex-1-9
<PAGE>

6.  Notice of Redemption

     Notice of redemption will be mailed at least 30 days but not more than 60
days before the redemption date to each Holder of Securities to be redeemed at
his registered address.  Securities in denominations larger than $1,000 may be
redeemed in part but only in whole multiples of $1,000.  If money sufficient
to pay the redemption price of and accrued interest on all Securities (or
portions thereof) to be redeemed on the redemption date is deposited with the
Paying Agent on or before the redemption date and certain other conditions are
satisfied, on and after such date interest ceases to accrue on such Securities
(or such portions thereof) called for redemption.

7.  Denominations; Transfer; Exchange

     The Securities are in registered form without coupons in denominations of
$1,000 and whole multiples of $1,000.  A Holder may transfer or exchange
Securities in accordance with the Indenture.  The Registrar may require a
Holder, among other things, to furnish appropriate endorsements or transfer
documents and to pay any taxes and fees required by law or permitted by the
Indenture.  The Registrar need not register the transfer of or exchange any
Securities selected for redemption (except, in the case of a Security to be
redeemed in part, the portion of the Security not to be redeemed) or any
Securities for a period of 15 days before a selection of Securities to be
redeemed or 15 days before an interest payment date.

8.  Persons Deemed Owners

     The registered Holder of this Security may be treated as the owner of it
for all purposes.

9.  Unclaimed Money

     If money for the payment of principal or interest remains unclaimed for
two years, the Trustee or Paying Agent shall pay the money back to the Company
at its request unless an abandoned property law designates another Person.
After any such payment, Holders entitled to the money must look only to the
Company and not to the Trustee for payment.

10.  Discharge and Defeasance

     Subject to certain conditions, the Company at any time may terminate some
or all of its obligations under the Securities and the Indenture if the
Company deposits with the Trustee money or U.S. Government Obligations for the
payment of principal and interest on the Securities to redemption or maturity,
as the case may be.

11.  Amendment, Waiver

     Subject to certain exceptions set forth in the Indenture, (i) the
Indenture or the Securities may be amended with the written consent of the
Holders of at least a majority in principal amount outstanding of the
Securities and (ii) any default or noncompliance with any provision may be
waived with the written consent of the Holders of a majority in principal
amount outstanding of the Securities.  Subject to certain exceptions set forth
in the Indenture, without the consent of any Securityholder, the Company and
the Trustee may amend the Indenture or the Securities to cure any ambiguity,
omission, defect or inconsistency, or to comply with Article 5 of the
Indenture, or to provide for uncertificated Securities in addition to or in
place of certificated Securities, or to add guarantees with respect to the
Securities or to secure the Securities, or to add additional covenants or
surrender rights and powers conferred on the Company, or to comply with any
request of the SEC in connection with qualifying the Indenture under the Act,
or to make any change that does not adversely affect the rights of any
Securityholder.

12.  Defaults and Remedies

     Under the Indenture, Events of Default include a (i) default in the
payment of any interest upon any of the Securities for 30 days or more after
such payment is due; (ii) default in the payment of the principal of and
premium, if any, on any of the Securities when due; (iii) default by the
Company in the performance, or breach, of any of its other covenants in the
Indenture which will not have been remedied by the end of a period of 60 days
after written notice to the Company by the Trustee or to the Company and the
Trustee by the Holders of at least 25% in principal amount of the outstanding
Securities; and (iv) certain events of bankruptcy, insolvency or
reorganization of the Company or a Significant Subsidiary.

     If an Event of Default occurs and is continuing, the Trustee or the
Holders of at least 25% in principal amount of the Securities may declare all
the Securities to be due and payable immediately.  Certain events of
bankruptcy or insolvency are Events of Default which will result in the
Securities being due and payable immediately upon the occurrence of such
Events of Default.

     Securityholders may not enforce the Indenture or the Securities except as
provided in the Indenture.  The Trustee may refuse to enforce the Indenture or
the Securities unless it receives reasonable indemnity or security.  Subject
to certain limitations, Holders of a majority in principal amount of the
Securities may direct the Trustee in its exercise of any trust or power.  The
Trustee may withhold from Securityholders notice of any continuing Default
(except a Default in payment of principal or interest) if it determines or its
counsel advises it that withholding notice is in the interest of the Holders.

<PAGE>

13.  Trustee Dealings with the Company

     Subject to certain limitations imposed by the Act, the Trustee under the
Indenture, in its individual or any other capacity, may become the owner or
pledgee of Securities and may otherwise deal with and collect obligations owed
to it by the Company or its Affiliates and may otherwise deal with the Company
or its Affiliates with the same rights it would have if it were not Trustee.

14.  No Recourse Against Others

     A director, officer, employee or stockholder, as such, of the Company or
the Trustee shall not have any liability for any obligations of the Company
under the Securities or the Indenture or for any claim based on, in respect of
or by reason of such obligations or their creation.  By accepting a Security,
each Securityholder waives and releases all such liability.  The waiver and
release are part of the consideration for the issue of the Securities.

15.  Authentication

     This Security shall not be valid until an authorized signatory of the
Trustee (or an authenticating agent) manually signs the certificate of
authentication on the other side of this Security.

16.  Abbreviations

     Customary abbreviations may be used in the name of a Securityholder or an
assignee, such as TEN COM (=tenants in common), TEN ENT (=tenants by the
entireties), JT TEN (=joint tenants with rights of survivorship and not as
tenants in common), CUST (=custodian), and U/G/M/A (=Uniform Gift to Minors
Act).

17.  Holders' Compliance with Registration Agreement.

     Each Holder of a Security, by acceptance hereof, acknowledges and agrees
to the provisions of the Registration Agreement, including, without
limitation, the obligations of the Holders with respect to a registration and
the indemnification of the Company to the extent provided therein.

18.  Governing Law

     THIS SECURITY SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE
LAWS OF THE STATE OF NEW YORK BUT WITHOUT GIVING EFFECT TO APPLICABLE
PRINCIPLES OF CONFLICTS OF LAW TO THE EXTENT THAT THE APPLICATION OF THE LAWS
OF ANOTHER JURISDICTION WOULD BE REQUIRED THEREBY.

19.  CUSIP Numbers

     Pursuant to a recommendation promulgated by the Committee on Uniform
Security Identification Procedures, the Company has caused CUSIP numbers to be
printed on the Securities and has directed the Trustee to use CUSIP numbers in
notices of redemption as a convenience to Securityholders.  No representation
is made as to the accuracy of such numbers either as printed on the Securities
or as contained in any notice of redemption and reliance may be placed only on
the other identification numbers placed thereon.

     The Company will furnish to any Securityholder upon written request and
without charge to the Securityholder a copy of the Indenture which has in it
the text of this Security in larger type.  Requests may be made to:

FORM OF REVERSE SIDE OF EXCHANGE SECURITY
OR PRIVATE EXCHANGE SECURITY


                             6.875% Note Due 2007


1.  Interest

     LOUIS DREYFUS NATURAL GAS CORP., an Oklahoma corporation (such 
corporation, and its successors and assigns under the Indenture hereinafter 
referred to, being herein called the "Company"), promises to pay interest on 
the principal amount of this Security at the rate per annum shown above 
[; provided, however, that if a Registration Default (as defined in the 
Registration Rights Agreement) occurs, additional interest will accrue on 
this Security at a rate of 0.25% per annum from and including the date on 
which any such Registration Default shall occur to but excluding the date on 
which all Registration Defaults have been cured].(1)  The Company will pay 
interest semiannually on June 1 and December 1 of each year.  Interest on the 
Securities will accrue from the most recent date to which interest has been 
paid or, if no interest has been paid, from December 11, 1997.  Interest will 
be computed on the basis of a 360-day year of twelve 30-day months.  The 
Company shall pay interest on overdue principal at the rate borne by the 
Securities plus 1% per annum, and it shall pay interest on overdue 
installments of interest at the same rate to the extent lawful.

2.  Method of Payment

The Company will pay interest on the Securities (except defaulted interest) 
to the Persons who are registered holders of Securities at the close of 
business on the April 1 or October 1 next preceding the interest payment date 
even if Securities are canceled after the record date and on or before the 
interest payment date.  Holders must surrender Securities to a Paying Agent 
to collect principal payments.  The Company will pay principal and interest 
in money of the United States that at the time of payment is legal tender for 
payment of public and private debts.  Payments in respect of Securities 
(including principal, premium and interest) will be made by wire transfer of 
immediately available funds to the accounts specified by the holders thereof 
or, if no U.S. dollar account maintained by the payee with a bank in the 
United States is designated by any holder to the Trustee or the Paying Agent 
at least 30 days prior to the relevant due date for payment (or such other 
date as the Trustee may accept in its discretion), by mailing a check to the 
registered address of such holder.

- -------------------------

(1) Insert if at the time of issuance of the Exchange Security or Private 
    Exchange Security (as the case may be) neither the Registered Exchange 
    Offer has been consummated nor a Shelf Registration Statement has been 
    declared effective in accordance with the Registration Rights Agreement.


                                       A-3

<PAGE>

3.  Paying Agent and Registrar

     Initially, LaSalle National Bank, a national banking association 
corporation ("Trustee"), will act as Paying Agent and Registrar.  The Company 
may appoint and change any Paying Agent, Registrar or co-registrar without 
notice.  The Company or any of its domestically incorporated Wholly-Owned 
Subsidiaries may act as Paying Agent, Registrar or co-registrar.

4.  Indenture

     The Company issued the Securities under an Indenture dated as of 
December 11, 1997 ("Indenture"), between the Company and the Trustee.  The 
terms of the Securities include those stated in the Indenture and those made 
part of the Indenture by reference to the Trust Indenture Act of 1939 (15 
U.S.C. Sections 77aaa-77bbbb) as in effect on the date of the Indenture (the 
"Act").  Terms defined in the Indenture and not defined herein have the 
meanings ascribed thereto in the Indenture.  The Securities are subject to 
all such terms, and Securityholders are referred to the Indenture and the Act 
for a statement of those terms.

     The Securities are general unsecured obligations of the Company limited 
to $200,000,000 aggregate principal amount (subject to Section 2.07 of the 
Indenture). 

     The Company will not, and will not permit any of its Subsidiaries to, 
create, incur or otherwise cause or suffer to exist or become effective any 
Liens of any kind upon any Principal Property or any shares of stock or 
indebtedness of any Subsidiary that owns or leases any Principal Property 
(whether such Principal Property, shares of stock or indebtedness are now 
owned or hereafter acquired) unless all payments due under the Indenture and 
the Securities are secured on an equal and ratable basis with the obligations 
so secured until such time as such obligation is no longer secured by a Lien, 
except for Permitted Liens.

     Neither the Company nor any Subsidiary will enter into any Sale and 
Leaseback Transaction with respect to any Principal Property unless either 
(a) the Company or such Subsidiary would be entitled, pursuant to the 
provisions of the Indenture, to incur Indebtedness secured by a Lien on the 
property to be leased without equally and ratably securing the Securities or 
(b) the Company, within 180 days after the effective date of such 
transaction, applies to the voluntary retirement of its funded debt an amount 
equal to the value of such transaction, defined as the greater of the net 
proceeds of the sale of the property leased in such transaction or the fair 
value, in the opinion of the Board of Directors, of the leased property at 
the time such transaction was entered into.

     Notwithstanding the foregoing limitations on Liens and Sale and 
Leaseback Transaction, the Company and its Subsidiaries may issue, assume, or 
guarantee Indebtedness secured by a Lien without securing the Securities, or 
may enter into Sale and Leaseback Transactions without retiring funded debt, 
or enter into a combination of such transactions, if the sum of the principal 
amount of all such 


                                       A-4

<PAGE>

Indebtedness and the aggregate value of all such Sale and Leaseback 
Transactions does not at any time exceed 15% of the Consolidated Net Tangible 
Assets of the Company.

5.  Optional Redemption

     The Securities will be redeemable at any time, at the option of the 
Company, in whole or from time to time in part, upon not less than 30 and not 
more than 60 days' notice mailed to each Holder to be redeemed at the 
Holder's address appearing in the books of the Registrar, on any date prior 
to maturity (the "Redemption Date") at a price equal to 100% of the principal 
amount thereof plus accrued interest to the Redemption Date (subject to the 
right of Holders of record on the relevant record date to receive interest 
due on an interest payment date that is on or prior to the Redemption Date) 
plus a Make-Whole Premium, if any (the "Redemption Price").  In no event will 
the Redemption Price ever be less than 100% of the principal amount of the 
Securities plus accrued interest to the Redemption Date.

     The amount of the Make-Whole Premium with respect to any Security (or 
portion thereof) to be redeemed will be equal to the excess, if any, of:

     (1) the sum of the present values, calculated as of the Redemption Date, 
of:

          (a) each interest payment that, but for such redemption, would have 
     been payable on the Security (or portion thereof) being redeemed on each 
     interest payment date occurring after the Redemption Date (excluding any 
     accrued interest for the period prior to the Redemption Date); and

          (b) the principal amount that, but for such redemption, would have 
     been payable at the final maturity of the Security (or portion thereof) 
     being redeemed;

          over

     (2) the principal amount of the Security (or portion thereof) being 
redeemed.  The present values of interest and principal payments referred to 
in clause (i) above will be determined in accordance with generally accepted 
principles of financial analysis.  Such present values will be calculated by 
discounting the amount of each payment of interest or principal from the date 
that each such payment would have been payable, but for the redemption, to 
the Redemption Date at a discount rate equal to the Treasury Yield (as 
defined below) plus 20 basis points.

     The Make-Whole Premium will be calculated by an independent investment 
banking institution of national standing appointed by the Company; provided, 
that if the Company fails to make such appointment at least 45 business days 
prior to the Redemption Date, or if the institution so appointed is unwilling 
or unable to make such calculation, such calculation will be made by Salomon 
Brothers Inc or, if such firm is unwilling or unable to make such 
calculation, by an independent investment banking 


                                       A-5

<PAGE>

institution of national standing appointed by the Trustee (in any such case, 
an "Independent Investment Banker").  Such fees are to be paid for by the 
Company.

     For purposes of determining the Make-Whole Premium, "Treasury Yield" 
means a rate of interest per annum equal to the weekly average yield to 
maturity of United States Treasury Notes that have a constant maturity that 
corresponds to the remaining term to maturity of the Securities, calculated 
to the nearest 1/12th of a year (the "Remaining Term").  The Treasury Yield 
will be determined as of the third business day immediately preceding the 
applicable Redemption Date.

     The weekly average yields of United States Treasury Notes will be 
determined by reference to the most recent statistical release published by 
the Federal Reserve Bank of New York and designated "H.15(519) Selected 
Interest Rates" or any successor release (the "H.15 Statistical Release").  
If the H.15 Statistical Release sets forth a weekly average yield for United 
States Treasury Notes having a constant maturity that is the same as the 
Remaining Term, then the Treasury Yield will be equal to such weekly average 
yield.  In all other cases, the Treasury Yield will be calculated by 
interpolation, on a straight-line basis, between the weekly average yields on 
the United States Treasury Notes that have a constant maturity closest to and 
greater than the Remaining Term and the United States Treasury Notes that 
have a constant maturity closest to and less than the Remaining Term (in each 
case as set forth in the H.15 Statistical Release).  Any weekly average 
yields so calculated by interpolation will be rounded to the nearest 1/100th 
of 1%, with any figure of 1/200th of 1% or above being rounded upward.  If 
weekly average yields for United States Treasury Notes are not available in 
the H.15 Statistical Release or otherwise, then the Treasury Yield will be 
calculated by interpolation of comparable rates selected by the Independent 
Investment Banker.

     In the case of any partial redemption, selection of the Securities for 
redemption will be made by the Trustee on a pro rata basis, by lot or by such 
other method as the Trustee in its sole discretion shall deem to be fair and 
appropriate, although no Security of $1,000 in original principal amount or 
less shall be redeemed in part.  If any Security is to be redeemed in part 
only, the notice of redemption relating to such Security shall state the 
portion of the principal amount thereof to be redeemed.  A new Security in 
principal amount equal to the unredeemed portion thereof will be issued in 
the name of the Holder thereof upon cancelation of the original Security.

6.  Notice of Redemption

     Notice of redemption will be mailed at least 30 days but not more than 
60 days before the redemption date to each Holder of Securities to be 
redeemed at his registered address.  Securities in denominations larger than 
$1,000 may be redeemed in part but only in whole multiples of $1,000.  If 
money sufficient to pay the redemption price of and accrued interest on all 
Securities (or portions thereof) to be redeemed on the redemption date is 
deposited with the Paying Agent on or before the redemption date and certain

7.  Denominations; Transfer; Exchange

     The Securities are in registered form without coupons in denominations 
of $1,000 and whole multiples of $1,000.  A Holder may transfer or exchange 
Securities in accordance with the Indenture.  The Registrar may require a 
Holder, among other things, to furnish appropriate endorsements or transfer 
documents and to pay any taxes and fees required by law or permitted by the 
Indenture.  The Registrar need not register the transfer of or exchange any 
Securities selected for redemption (except, in the case of a Security to be 
redeemed in part, the portion of the Security not to be redeemed) or any 
Securities for a period of 15 days before a selection of Securities to be 
redeemed or 15 days before an interest payment date.

8.  Persons Deemed Owners

     The registered Holder of this Security may be treated as the owner of it 
for all purposes.

9.  Unclaimed Money

     If money for the payment of principal or interest remains unclaimed for 
two years, the Trustee or Paying Agent shall pay the money back to the 
Company at its request unless an abandoned property law designates another 
Person.  After any such payment, Holders entitled to the money must look only 
to the Company and not to the Trustee for payment.

10.  Discharge and Defeasance

     Subject to certain conditions, the Company at any time may terminate 
some or all of its obligations under the Securities and the Indenture if the 
Company deposits with the Trustee money or U.S. Government Obligations for 
the payment of principal and interest on the Securities to redemption or 
maturity, as the case may be.

11.  Amendment, Waiver

     Subject to certain exceptions set forth in the Indenture, (i) the 
Indenture or the Securities may be amended with the written consent of the 
Holders of at least a majority in principal amount outstanding of the 
Securities and (ii) any default or noncompliance with any provision may be 
waived with the written consent of the Holders of a majority in principal 
amount outstanding of the Securities.  Subject to certain exceptions set 
forth in the Indenture, without the consent of any Securityholder, the 
Company and the Trustee may amend the Indenture or the Securities to cure any 
ambiguity, omission, defect or inconsistency, or to comply with Article 5 of 
the Indenture, or to provide for uncertificated Securities in addition to or 
in place of certificated Securities, or to add guarantees with respect to the 
Securities or to secure the Securities, or to add additional covenants or 
surrender rights and powers conferred on the Company, or to comply with any 
request of the SEC in connection with qualifying the 


                                       A-7

<PAGE>

Indenture under the Act, or to make any change that does not adversely affect 
the rights of any Securityholder.

12.  Defaults and Remedies

     Under the Indenture, Events of Default include a (i) default in the 
payment of any interest upon any of the Securities for 30 days or more after 
such payment is due; (ii) default in the payment of the principal of and 
premium, if any, on any of the Securities when due; (iii) default by the 
Company in the performance, or breach, of any of its other covenants in the 
Indenture which will not have been remedied by the end of a period of 60 days 
after written notice to the Company by the Trustee or to the Company and the 
Trustee by the Holders of at least 25% in principal amount of the outstanding 
Securities; and (iv) certain events of bankruptcy, insolvency or 
reorganization of the Company or a Significant Subsidiary.

     If an Event of Default occurs and is continuing, the Trustee or the 
Holders of at least 25% in principal amount of the Securities may declare all 
the Securities to be due and payable immediately.  Certain events of 
bankruptcy or insolvency are Events of Default which will result in the 
Securities being due and payable immediately upon the occurrence of such 
Events of Default.

     Securityholders may not enforce the Indenture or the Securities except 
as provided in the Indenture.  The Trustee may refuse to enforce the 
Indenture or the Securities unless it receives reasonable indemnity or 
security.  Subject to certain limitations, Holders of a majority in principal 
amount of the Securities may direct the Trustee in its exercise of any trust 
or power.  The Trustee may withhold from Securityholders notice of any 
continuing Default (except a Default in payment of principal or interest) if 
it determines that withholding notice is in the interest of the Holders.

13.  Trustee Dealings with the Company

     Subject to certain limitations imposed by the Act, the Trustee under 
the Indenture, in its individual or any other capacity, may become the owner 
or pledgee of Securities and may otherwise deal with and collect obligations 
owed to it by the Company or its Affiliates and may otherwise deal with the 
Company or its Affiliates with the same rights it would have if it were not 
Trustee.

14.  No Recourse Against Others

     A director, officer, employee or stockholder, as such, of the Company or 
the Trustee shall not have any liability for any obligations of the Company 
under the Securities or the Indenture or for any claim based on, in respect 
of or by reason of such obligations or their creation.  By accepting a 
Security, each Securityholder waives and releases all such liability.  The 
waiver and release are part of the consideration for the issue of the 
Securities.

15.  Authentication

     This Security shall not be valid until an authorized signatory of the 
Trustee (or an authenticating agent) manually signs the certificate of 
authentication on the other side of this Security.

16.  Abbreviations

     Customary abbreviations may be used in the name of a Securityholder or 
an assignee, such as TEN COM (=tenants in common), TEN ENT (=tenants by the 
entireties), JT TEN (=joint tenants with rights of survivorship and not as

to the provisions of the Registration Rights Agreement, including, without

PRINCIPLES OF CONFLICTS OF LAW TO THE EXTENT THAT THE APPLICATION OF THE LAWS 
OF ANOTHER JURISDICTION WOULD BE REQUIRED THEREBY.

19.  CUSIP Numbers

     Pursuant to a recommendation promulgated by the Committee on Uniform 
Security Identification Procedures the Company has caused CUSIP numbers to be 
printed on the Securities and has directed the Trustee to use CUSIP numbers 
in notices of redemption as a convenience to Securityholders.  No 
representation is made as to the accuracy of such numbers either as printed 
on the Securities or as contained in any notice of redemption and reliance 
may be placed only on the other identification numbers placed thereon.

Ladies and Gentlemen:

     Louis Dreyfus Natural Gas Corp., an Oklahoma corporation (the "Company"),
proposes to issue and sell to you (the "Purchasers"), $200,000,000 aggregate
principal amount of its 6.875% Senior Notes Due December 1, 2007 (the
"Securities").  The Securities are to be issued under an indenture (the
"Indenture") to be dated as of December 11, 1997, between the Company and
LaSalle National Bank, as trustee (the "Trustee").

     The sale of the Securities to you will be made without registration of
the Securities under the Securities Act of 1933, as amended (the "Securities
Act"), in reliance upon exemptions from the registration requirements of the
Securities Act.  You have advised the Company that you will make an offering
of the Securities purchased by you hereunder in accordance with Section 4
hereof as soon as you deem advisable after the execution and delivery of this
Agreement.

<PAGE>

     In connection with the sale of the Securities, the Company has prepared a
preliminary offering memorandum, dated October 16, 1997 (the "Preliminary
Memorandum"), and a final offering memorandum, dated December 4, 1997 (the
"Final Memorandum").  Each of the Preliminary Memorandum and the Final
Memorandum sets forth certain information concerning the Company and the
Securities.  The Company hereby confirms that it has authorized the use of the
Preliminary Memorandum and the Final Memorandum, and any amendment or
supplement thereto, in connection with the offer and sale of the Securities by
the Purchasers.  Any references herein to the Preliminary Memorandum or the
Final Memorandum shall be deemed to include all exhibits thereto and all
documents incorporated by reference therein which were filed under the
Securities Act or the Securities Exchange Act of 1934, as amended (the
"Exchange Act"), on or before the Execution Time (as defined below); and any
reference herein to the terms "amend", "amendment" or "supplement" with
respect to the Final Memorandum shall be deemed to refer to and include the
filing of any document under the Exchange Act after the Execution Time which
is incorporated by reference therein.

     Holders (including subsequent transferees) of the Securities will have
the registration rights set forth in the Registration Agreement dated as of
the Closing Date (the "Registration Agreement") to be entered into between the
Company and the Purchasers.  Pursuant to the Registration Agreement, the
Company has agreed to file with the Securities and Exchange Commission (the
"Commission") an exchange offer registration statement or a shelf registration
statement (each, a "Registration Statement") pursuant to the Securities Act,
to register sales, or resales, of the Securities following the sale of the
Securities contemplated hereby.  "Execution Time" shall mean the date and time
that this Agreement is executed and delivered by the parties hereto.

     1.  Representations and Warranties.  The Company represents and warrants
to, and agrees with, each Purchaser as set forth below in this Section 1:

          (a)  The Preliminary Memorandum and the Final Memorandum and any
     amendments or supplements thereto did not and will not, as of their
     respective dates, contain an untrue statement of a material fact or omit
     to state a material fact necessary in order to make the statements
     therein, in the light of the circumstances under which they were made,
     not misleading.  The preceding sentence does not apply to statements in
     or omissions from the Final Memorandum based upon written information
     furnished to the Company by any Purchaser specifically for use therein,
     it being understood and agreed that the only such information is that
     described as such in Section 8(b) hereof.  The Company's Annual Report on
     Form 10-K most recently filed with the Commission, as amended, and all
     subsequent reports (as originally filed, and as amended), on the
     respective dates filed by the Company (collectively, the "Exchange Act
     Reports") which have been filed by the Company with the Commission or
     sent to stockholders pursuant to the Exchange Act do not include any
     untrue statement of a material fact or omit to state any material fact
     necessary to make the

                                     2
<PAGE>

     statements therein, in the light of the circumstances under which they
     were made, not misleading.  Such Exchange Act Reports, when they were
     filed with the Commission, conformed in all material respects to the
     requirements of the Exchange Act and the rules and regulations of the
     Commission thereunder.

          (b)  The offer and sale of the Securities in the manner contemplated
     by this Agreement will be exempt from the registration requirements of
     the Securities Act by reason of Section 4(2) thereof, and Rule 144A
     ("Rule 144A") and Regulation S ("Regulation S") thereunder.

          (c)  Neither the Company nor any affiliate (as defined in Rule 501(b)
     of Regulation D under the Securities Act ("Regulation D")), nor any
     person acting on behalf of the Company or any affiliate has directly, or
     indirectly, (i) made offers or sales of any security, or solicited offers
     to buy any security, under circumstances that would require the
     registration of the Securities under the Securities Act or (ii) engaged
     in any form of general solicitation or general advertising (within the
     meaning of Regulation D) in connection with the offering of the
     Securities.

          (d)  Neither the Company nor any affiliate nor any person acting on
     behalf of the Company or any affiliate has engaged in any directed
     selling efforts (as that term is defined in Regulation S) with respect to
     the Securities, and the Company and its affiliates and any person acting
     on its or their behalf have complied with the offering restrictions
     requirement of Regulation S.

          (e)  The Securities satisfy the eligibility requirements set forth
     in Rule 144A(d)(3) under the Securities Act.

          (f)  The Company has full corporate power and authority to enter
     into this Agreement, the Registration Agreement, the Indenture and the
     Securities and to perform the transactions contemplated hereby and
     thereby (the "Transactions").  (i) This Agreement has been duly
     authorized, executed and delivered by the Company and constitutes a valid
     and binding obligation of the Company and (ii) the execution and delivery
     of the Registration Agreement, the Indenture and the Securities have been
     duly authorized by the Company and, when duly executed and delivered by
     the parties thereto, will constitute valid and binding obligations of the
     Company, enforceable against the Company in accordance with their
     respective terms, subject to applicable bankruptcy, insolvency,
     reorgani-zation, moratorium and similar laws affecting creditors' rights
     and remedies generally and to general principles of equity (regardless of
     whether enforcement is sought in a proceeding at law or in equity).

                                     3
<PAGE>

          (g)  Upon execution and delivery of the Indenture, and when the
     Securities are issued, authenticated and delivered in accordance with the
     Inden-ture and paid for in accordance with the terms of this Agreement,
     the Securities will constitute valid and binding obligations of the
     Company enforceable against the Company in accordance with their terms
     and entitled to the benefits of the Indenture, subject to applicable
     bankruptcy, insolvency, reorganization, morato-rium and similar laws
     affecting creditors' rights and remedies generally and to general
     principles of equity (regardless of whether enforcement is sought in a
     proceeding at law or in equity).

          (h)  The execution, delivery and performance of this Agreement, the
     Registration Agreement, the Indenture and the Securities by the Company
     and the consummation of the Transactions will not result in a breach or
     violation of any of the terms and provisions of, or constitute a default
     under (i) the articles of incorporation, by-laws or other organizational
     documents of the Company or any of its subsidiaries, (ii) any material
     statute, rule or regulation applicable to the Company or any subsidiary
     or any order of any governmental agency or body or any court having
     jurisdiction over the Company or any subsidiary or any of their
     respective properties, (iii) any agreement or instrument relating to
     borrowed money to which the Company or any subsidiary is a party or by
     which the Company or any subsidiary is bound or to which any of their
     respective properties is subject, or (iv) any other material agreement or
     instrument to which the Company or any of its subsidiaries is a party or
     by which the Company or any of its subsidiaries is bound or to which any
     of their respective properties is subject.  No consent, approval,
     authorization or other order of any court, regulatory body,
     administrative agency or other governmental body which has not already
     been obtained is required for the execution and delivery of this
     Agreement, the Registration Agreement, the Indenture, the Securities or
     the consummation of the Transactions, except for compliance with the
     Securities Act, state securities or blue sky laws and the clearance of
     such offering with the National Association of Securities Dealers, Inc.
     The term "subsidiary" means each person of which a majority of the voting
     equity securities or other interests is owned, directly or indirectly, by
     the Company.

          (i)  It is not necessary in connection with the offer, sale and
     delivery of the Securities in the manner contemplated by this Agreement
     and the Final Memorandum to qualify the Indenture under the Trust
     Indenture Act of 1939, as amended (the "Trust Indenture Act").

          (j)  The Company is not an open-end investment company, unit
     investment trust or face-amount certificate company that is or is
     required to be registered under Section 8 of the United States Investment
     Company Act of 1940 (the "Investment Company Act"), nor is it a closed
     end investment company required to be registered, but not registered
     thereunder; and the Company is not and, after giving effect to the
     offering and sale of the Securities and

                                     4
<PAGE>

     the application of the proceeds thereof as described in the Final
     Memorandum, will not be an "investment company" as defined in the
     Investment Company Act.

          (k)  The Company is subject to the reporting requirements of Section
     13 or 15(d) under the Exchange Act.

     2.  Purchase and Sale.  Subject to the terms and conditions and in 
reliance upon the representations and warranties herein set forth, the Company 
agrees to sell to each Purchaser, and each Purchaser agrees, severally and not 
jointly, to purchase from the Company, at a purchase price of 98.642% of the 
principal amount thereof, plus accrued interest, if any, from December 11,

Purchasers against payment by the Purchasers of the purchase price thereof to

subject to, the registration requirements of the Securities Act or pursuant to
an effective registration statement under the Securities Act and (ii)
severally and not jointly, represents and warrants to and agrees, with the
Company that:

          (a)  It has not offered or sold, and will not offer or sell, any
     Securities except (i) to those it reasonably believes to be qualified
     institutional buyers (as defined in Rule 144A under the Securities Act)
     and that, in connection with each such sale, it has taken or will take

                                     5
<PAGE>

     reasonable steps to ensure that the purchaser of such Securities is aware
     that such sale is being made in reliance on Rule 144A or (ii) in
     accordance with the restrictions set forth in Exhibit A hereto.

          (b)  Neither it nor any person acting on its behalf has made or will
     make offers or sales of the Securities in the United States by means of
     any form of general solicitation or general advertising (within the

     registered public offering as provided in the Registration Agreement.

     5.  AGREEMENTS.  The Company agrees with the several Purchasers that:

          (a)  The Company will furnish to the Purchasers, without charge, as
     many copies of the Final Memorandum and any supplements and amendments
     thereof or thereto as the Purchasers may reasonably request.  The Company
     will pay the expenses of printing or other production of all documents
     relating to the offering.

          (b)  The Company will not amend or supplement the Final Memorandum
     at any time prior to the completion of the sale of the Securities by the
     Purchasers if the Purchasers reasonably object to such amendment or
     supplement within two business days after receiving a copy thereof.

          (c)  If at any time prior to the completion of the sale of the
     Securities by the Purchasers, any event occurs as a result of which the
     Final Memorandum as then amended or supplemented would include any untrue
     statement of a material fact or omit to state any material fact necessary
     to make the state-ments therein in the light of the circumstances under
     which they were made not misleading, or if it shall be necessary to amend
     or supplement the Final Memorandum to comply with applicable law, the
     Company will promptly notify the Purchasers of the same and will prepare
     and provide to the Purchasers the proposed amendment or supplement which
     will correct such statement or omission or effect such compliance and
     will not publish such amendment or supplement if the Purchasers
     reasonably object to such amendment or supplement within two business
     days after receiving a copy thereof.

          (d)  Except as provided in Exhibit A, the Company will arrange for
     the qualification of the Securities for sale by the Purchasers under the
     laws of such jurisdictions as the Purchasers may designate and will
     maintain such qualifications in effect so long as required for the sale
     of the Securities; provided, however, the Company shall not be required
     to do business in any jurisdiction where it is not now so qualified or to
     take any action which would subject it to general or unlimited service of
     process or taxation in any jurisdiction where it is not now so subject.
     The Company will promptly advise the Purchasers of the

                                     6
<PAGE>

     receipt by it of any notification with respect to the suspension of the
     qualification of the Securities for sale in any jurisdiction or the
     initiation or threatening of any proceeding for such purpose.

          (e)  Neither the Company nor any of its Affiliates, nor any person
     acting on behalf of the Company or any of its affiliates, will engage in
     any form of general solicitation or general advertising (within the
     meaning of Regulation D) in connection with any offer or sale of the
     Securities in the United States, except pursuant to a registered public
     offering as provided in the Registration Agreement.

          (f)  So long as any of the Securities are "restricted securities"
     within the meaning of Rule 144(a)(3) under the Securities Act, the
     Company will, for so long as and at any time that it is not subject to
     Section 13 or 15(d) of the Exchange Act, provide to each holder of such
     restricted securities and to each prospective purchaser (as designated by
     such holder) of such restricted securities, upon the request of such
     holder or prospective purchaser, any information required to be provided
     by Rule 144A(d)(4) under the Securities Act.  This covenant is intended
     to be for the benefit of the holders, and the prospective purchasers
     designated by such holders, from time to time of such restricted
     securities.

          (g)  Neither the Company nor any of its affiliates, nor any person
     acting on behalf of the Company or any of its affiliates, will engage in
     any directed selling efforts with respect to the Securities except
     pursuant to a registered public offering as provided in the Registration
     Agreement, and each of them will comply with the offering restrictions
     requirement of Regulation S.  Terms used in this paragraph have the
     meanings given to them by Regulation S.

          (h)  Neither the Company nor any of its affiliates, nor any person
     acting on behalf of the Company or any of its affiliates, will sell,
     offer for sale or solicit offers to buy or otherwise negotiate in respect
     of any security (as defined in the Securities Act) the offering of which
     security will be integrated with the sale of the Securities in a manner
     which would require the registration of the Securities under the
     Securities Act (except as provided in the Registration Agreement).

          (i)  The Company shall include information substantially in the form
     set forth in Exhibit B in each Final Memorandum.

          (j)  The Company shall use its best efforts in cooperation with the
     Purchasers to permit the Securities to be eligible for clearance and
     settlement through The Depository Trust Company.

                                     7

          (k)  The Company will not, until 180 days following the Closing
     Date, without the prior written consent of the Purchasers, offer, sell or
     contract to sell, or otherwise dispose of, directly or indirectly, or
     announce the offering of, or file a registration statement for, any debt
     securities issued or guaranteed by the Company (other than (i) the
     Securities or (ii) pursuant to a registered public offering as provided
     in the Registration Agreement).  The Company will not at any time offer,
     sell, contract to sell or otherwise dispose of, directly or indirectly,
     any securities under circumstances where such offer, sale, contract or
     disposition would cause the exemption afforded by Section 4(2) of the
     Securities Act or the safe harbor of Regulation S thereunder to cease to
     be applicable to the offer and sale of the Securities as contemplated by
     this Agreement and the Final Memorandum.

          (l)  In connection with the offering, until the Purchasers shall
     have notified the Company of the completion of the resale of the
     Securities, neither the Company nor any of its affiliates has or will,
     either alone or with one or more other persons, bid for or purchased for
     any account in which it or any of its affiliates has a beneficial
     interest any Securities or attempt to induce any person to purchase any
     Securities; and neither it nor any of its affiliates will make bids or
     purchases for the purpose of creating actual, or apparent, active trading
     in, or of raising the price of, the Securities.

     6.  Conditions to the Obligations of the Purchasers.  The obligations of
the Purchasers to purchase the Securities, shall be subject to the accuracy of
the representations and warranties on the part of the Company contained herein
as of the Execution Time, the Closing Date and any settlement date pursuant to
Section 3 hereof, to the accuracy of the statements of the Company made in any
certificates pursuant to the provisions hereof, to the performance by the
Company of its obligations hereunder and to the following additional conditions
precedent:

          (a)  The Company shall have furnished to the Purchasers the opinion
     of Crowe & Dunlevy, counsel for the Company, dated the Closing Date, to
     the effect that:

               (i) each of the Company and its subsidiary, Louis Dreyfus Gas
          Marketing Corp. (the "Subsidiary"), has been duly incorporated and
          is validly existing as a corporation in good standing under the laws
          of the jurisdiction in which it is chartered or organized, with full
          corporate power and authority to own its properties and conduct its
          business as described in the Final Memorandum, and is duly qualified
          to do business as a foreign corporation and is in good standing
          under the laws of each jurisdiction which requires such
          qualification wherein it owns or leases material properties or
          conducts material business;

              (ii) all the outstanding shares of capital stock of the
          Subsidiary have been duly and validly authorized and issued and are
          fully paid and nonassessable, and, except

                                     8
<PAGE>

          as otherwise set forth in the Final Memorandum, all outstanding
          shares of capital stock of the Subsidiary are owned by the Company
          either directly or through wholly owned subsidiaries free and clear
          of any perfected security interest and, to the knowledge of such
          counsel, after due inquiry, any other security interests, claims,
          liens or encumbrances;

             (iii) the Company's authorized equity capitalization is as set
          forth in the Final Memorandum; and the Securities conform to the
          description thereof contained in the Final Memorandum;

              (iv) the Indenture has been duly authorized, executed and
          delivered, and constitutes a legal, valid and binding instrument
          enforceable against the Company in accordance with its terms
          (subject, as to enforcement of remedies, to applicable bankruptcy,
          reorganization, insolvency, moratorium or other laws affecting
          creditors' rights generally from time to time in effect); and the
          Securities have been duly authorized and, when executed and
          authenticated in accordance with the provisions of the Indenture and
          delivered to and paid for by the Purchasers pursuant to this
          Agreement, will constitute legal, valid and binding obligations of
          the Company entitled to the benefits of the Indenture;

               (v) the statements in the Final Memorandum under the heading
          "Certain Federal Income Tax Consequences" fairly summarize the
          matters therein described;

              (vi) such counsel has no reason to believe that as of the
          Execution Time the Final Memorandum (other than the financial
          statements and other financial information contained therein, as to
          which such counsel need express no opinion) contained any untrue
          statement of a material fact or omitted to state any material fact
          required to be stated therein or necessary to make the state-ments
          therein not misleading or that the Final Memorandum includes any
          untrue statement of a material fact or omits to state a material
          fact necessary to make the statements therein, in the light of the
          circumstances under which they were made, not misleading;

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

            (viii) no consent, approval, authorization or order of any court
          or governmental agency or body is required for the consummation of
          the transactions contemplated herein, except (A) such as may be
          required under the blue sky laws of any jurisdiction in connection
          with the purchase and distribution of the Securities by the

                                     9
<PAGE>

          Purchasers, (B) with respect to the Exchange Offer (as defined in
          the Final Memorandum) and the Shelf Registration Statement (as
          defined in the Final Memorandum), filings or registration under the
          Securities Act or the Exchange Act and (C) such other approvals
          (specified in such opinion) as have been obtained;

              (ix) the Indenture conforms as to form in all material respects
          with the requirements of the Trust Indenture Act and the rules and
          regulations of the Commission applicable to an indenture which is
          qualified thereunder;

               (x) neither the issue and sale of the Securities, the execution
          and delivery of the Indenture, the consummation of any other of the
          transactions herein contemplated nor the fulfillment of the terms
          hereof will conflict with, result in a breach or violation of, or
          constitute a default under any law or the charter or by-laws of the
          Company or the terms of any indenture or other agreement or
          instrument known to such counsel and to which the Company or any of
          its subsidiaries is a party or bound or any judgment, order or
          decree known to such counsel to be applicable to the Company or any
          of its subsidiaries of any court, regulatory body, administrative
          agency, governmental body or arbitrator having jurisdiction over the
          Company or any of its subsidiaries; and

              (xi) it is not necessary in connection with the offer, sale and
          delivery of the Securities in the manner contemplated by this
          Agreement to register the Securities under the Securities Act or to
          qualify the Indenture under the Trust Indenture Act.

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

          (b)  The Purchasers shall have received from Cravath, Swaine &
     Moore, counsel for the Purchasers, such opinion or opinions, dated the
     Closing Date, with respect to the issuance and sale of the Securities,
     the Final Memorandum (other than the financial statements and related
     schedules therein, as to which such counsel need express no view) and
     other related matters as the Purchasers may reasonably require, and the
     Company shall have furnished to such counsel such documents as they
     request for the purpose of enabling them to pass upon such matters.

                                     10

<PAGE>

          (c)  The Company shall have furnished to the Purchasers a
     certificate of the Company, signed by the Chairman of the Board or the
     President and the principal financial or accounting officer of the
     Company, dated the Closing Date, to the effect that the signers of such
     certificate have carefully examined the Final Memorandum together with
     any supplements thereto and this Agreement and that:

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

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

          (d)  At the Closing Date, Ernst & Young LLP shall have furnished to
     the Purchasers a letter or letters, dated as of the Closing Date, in form
     and substance satisfactory to the Purchasers, confirming that they are
     independent accountants within the meaning of the Securities Act and the
     applicable published rules and regulations thereunder and that they have
     performed a review of the unaudited interim financial information for the
     nine-month period ending September 30, 1997, in accordance with Statement
     of Auditing Standards No. 71 and stating in effect that:

               (i) in their opinion the audited financial statements and
          financial statement schedules reported on by them and the pro forma
          financial statements included or incorporated in the Final
          Memorandum comply in form in all material respects with the
          applicable accounting requirements of the Securities Act and the
          Exchange Act and the related published rules and regulations
          thereunder that would apply to the Final Memorandum if the Final
          Memorandum were a prospectus included in a registration statement on
          Form S-3 under the Securities Act;

              (ii) on the basis of a reading of the latest unaudited financial
          statements made available by the Company and its subsidiaries; their
          limited review in accordance with standards established by the
          American Institute of Certified Public Accountants under Statement
          of Auditing Standards No. 71 of the unaudited interim financial
          information for the nine-month period ended September 30, 1997, and
          as at

                                     11
<PAGE>

          September 30, 1997; carrying out certain specified procedures (but
          not an examination in accordance with generally accepted auditing
          standards) which would not necessarily reveal matters of
          significance with respect to the comments set forth in such letter;
          a reading of the minutes of the meetings of the stockholders,
          directors and committees of the Company and its subsidiaries; and
          inquiries of certain officials of the Company who have
          responsibility for financial and accounting matters of the Company
          and its subsidiaries as to transactions and events subsequent to
          December 31, 1996, nothing came to their attention which caused them
          to believe that:

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

                    (2) with respect to the period subsequent to September 30,
               1997, there were any changes, at a specified date not more than
               three business days prior to the date of the letter, in the
               long-term debt of the Company and its subsidiaries or capital
               stock of the Company or decreases in the stockholders' equity
               of the Company or decreases in working capital of the Company
               and its subsidiaries as compared with the amounts shown on the
               September 30, 1997, consolidated balance sheet included or
               incorporated by reference in the Final Memorandum, or for the
               period from October 1, 1997, to such specified date there were
               any decreases, as compared with the corresponding period in the
               preceding year in operating income, net revenues or income
               before income taxes or in total or per share amounts of net
               income of the Company and its subsidiaries, except in all
               instances for changes or decreases set forth in such letter, in
               which case the letter shall be accompanied by an explanation by
               the Company as to the significance thereof unless said
               explanation is not deemed necessary by the Purchasers;

             (iii) they have performed certain other specified procedures as a
          result of which they determined that certain information of an
          accounting, financial or statistical nature (which is limited to
          accounting, financial or statistical information derived from the
          general accounting records of the Company and its subsidiaries) set
          forth in the Final Memorandum and the documents incorporated by
          reference therein,

                                     12
<PAGE>

          including the information set forth under the captions "Summary",
          "Use of Proceeds" and "Capitalization", and certain other specified
          information incorporated by reference in the Final Memorandum agrees
          with the accounting records of the Company and its subsidiaries,
          excluding any questions of legal interpretation; and

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

     References to the Final Memorandum in this paragraph (d) include any
supplement thereto at the date of the letter.

          (e)  At the Execution Time, Arthur Andersen LLP shall have furnished
     to the Purchasers a letter, dated as of November 20, 1997, in form and
     substance satisfactory to the Purchasers, confirming that they are
     independent accountants with respect to the Company within the meaning of
     Rule 101 of the American Institute of Certified Public Accountants' Code
     of Professional Conduct and its interpretations and rulings and stating
     in effect that:

               (i) in their opinion the audited financial statements and
          financial statement schedules incorporated in the Final Memorandum
          and reported on by them comply in form in all material respects with
          the applicable accounting requirements of the Securities Act and the
          Exchange Act and the related published rules and regulations
          thereunder that would apply to the Final Memorandum if the Final
          Memorandum were a prospectus included in a registration statement on
          Form S-3 under the Securities Act;

              (ii) on the basis of a reading of the latest unaudited financial
          statements made available by American Exploration Company
          ("American") and its subsidiaries; their limited review in
          accordance with standards established by the American Institute of
          Certified Public Accountants under Statement of Auditing Standards
          No. 71 of the unaudited interim financial information for the
          six-month period ended June 30, 1997, and as at June 30, 1997;
          carrying out certain specified procedures (but not an examination in
          accordance with generally accepted auditing standards) which would

                                     13
<PAGE>

          not necessarily reveal matters of significance with respect to the
          comments set forth in such letter; a reading of the minutes of the
          meetings of the stockholders, directors and committees of American
          and its subsidiaries; and inquiries of certain officials of American
          who have responsibility for financial and accounting matters of
          American and its subsidiaries as to transactions and events
          subsequent to December 31, 1996, nothing came to their attention
          which caused them to believe that any unaudited financial statements
          incorporated in the Final Memorandum do not comply in form in all
          material respects with applicable accounting requirements and with
          the published rules and regulations of the Commission with respect
          to financial statements included or incorporated in quarterly
          reports on Form 10-Q under the Exchange Act; and said unaudited
          financial statements are not in conformity with generally accepted
          accounting principles applied on a basis substantially consistent
          with that of the audited financial statements included in the Final
          Memorandum; and

             (iii) they have performed certain other specified procedures as a
          result of which they determined that certain information of an
          accounting, financial or statistical nature (which is limited to
          accounting, financial or statistical information derived from the
          general accounting records of the Company and its subsidiaries)
          incorporated by reference in the Final Memorandum agrees with the
          accounting records of American and its subsidiaries, excluding any
          questions of legal interpretation;

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

          (f)  Subsequent to the Execution Time or, if earlier, the dates as
     of which information is given in the Final Memorandum (exclusive of any
     supplement thereto), there shall not have been (i) any change or decrease
     specified in the letter or letters referred to in paragraph (d) of this
     Section 6 or (ii) any change, or any development involving a prospective
     change, in or affecting the business or properties of the Company and its
     subsidiaries the effect of which, in any case referred to in clause (i)
     or (ii) above, is, in the judgment of the Purchasers, so material and
     adverse as to make it impractical or inadvisable to proceed with the
     offering or delivery of the Securities as contemplated by the Final
     Memorandum (exclusive of any supplement thereto).

          (g)  As of the Closing Date, the Securities shall be rated not lower
     than BBB- by Standard & Poor's Ratings Services and Ba1 by Moody's
     Investors Service.  Subsequent to the Execution Time, there shall not
     have been (i) any decrease in the rating of any of the Company's debt
     securities by any "nationally recognized statistical rating organization"
     (as defined for purposes of Rule 436(g) under the Securities Act) or (ii)
     any notice given of any

                                     14
<PAGE>

     intended or potential decrease in any such rating or of a possible change
     in any such rating that does not indicate the direction of the possible
     change.

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

          (i)  The Registration Agreement shall have been duly executed and
     delivered by the Company.

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

     The documents required to be delivered by this Section 6 shall be
delivered at the office of Cravath, Swaine & Moore, counsel for the
Purchasers, at Worldwide Plaza, 825 Eighth Avenue, New York, New York, on the
Closing Date.

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

     8.  INDEMNIFICATION AND CONTRIBUTION.

          (a)  The Company agrees to indemnify and hold harmless each
     Purchaser, the directors, officers, employees and agents of each
     Purchaser and each person who controls any Purchaser within the meaning
     of either the Securities Act or the Exchange Act against any and all
     losses, claims, damages or liabilities, joint or several, to which they
     or any of them may become subject under the Securities Act, the Exchange
     Act or otherwise, insofar as such losses, claims, damages or liabilities
     (or actions in respect thereof) arise out of or are based upon any untrue
     statement or alleged untrue statement of any material fact contained in
     the Preliminary Memorandum or the Final Memorandum or any amendment or

                                     15

     supplement thereto, or the incorporated Exchange Act Reports, or arise
     out of or are based upon the omission or alleged omission to state
     therein a material fact required to be stated therein or necessary in
     order to make the statements therein not misleading, and, subject to
     Section 8(c), will reimburse each Purchaser, promptly after the receipt
     of demand therefor accompanied by an invoice in reasonable detail, for
     any legal or other expenses reasonably incurred by them in connection
     with investigating or defending any such loss, claim, damage, liability
     or action; PROVIDED, HOWEVER, that the Company will not be liable in any
     such case to the extent that any such loss, claim, damage or liability
     arises out of or is based upon any such untrue statement or alleged
     untrue statement or omission or alleged omission made therein in reliance
     upon and in conformity with written information furnished to the Company
     by or on behalf of any Purchaser through Salomon Smith Barney
     specifically for inclusion therein, it being understood and agreed that
     the only such information consists of the information described as such
     in subsection (b) below; and PROVIDED, FURTHER, that with respect to any
     untrue statement or alleged untrue statement in or omission or alleged
     omission from the Preliminary Memorandum, the indemnity agreement
     contained in this subsection (a) shall not inure to the benefit of any
     Purchaser that sold the Securities concerned to the person asserting any
     such losses, claims, damages or liabilities, to the extent that such sale
     was an initial resale by such Purchaser and any such loss, claim, damage
     or liability of such Purchaser results from the fact that there was not
     sent or given to such person, at or prior to the written confirmation of
     the sale of such Securities to such person, a copy of the Final
     Memorandum (exclusive of any material included therein but not attached
     thereto) if the Company had previously furnished copies thereof to such
     Purchaser.  This indemnity agreement will be in addition to any liability
     which the Company may otherwise have.

          (b)  Each Purchaser will severally and not jointly indemnify and
     hold harmless the Company, each of its directors, each of its officers,
     and each person who controls the Company within the meaning of either the
     Securities Act or the Exchange Act, to the same extent as the foregoing
     indemnity from the Company to each Purchaser, but only with reference to
     written information relating to such Purchaser furnished to the Company
     by or on behalf of such Purchaser through Salomon Smith Barney
     specifically for inclusion in the documents referred to in the foregoing
     indemnity, it being understood and agreed that the only such information
     furnished by any Purchaser consists of the following information in the
     Final Memorandum furnished on behalf of each Purchaser:  The last
     paragraph at the bottom of the cover page concerning the terms of the
     offering by the Purchasers, the legend concerning stabilizing on page
     three of the Final Memorandum, the second sentence of the fourth
     paragraph and the seventh paragraph, each under the caption "Plan of
     Distribution."  This indemnity agreement will be in addition to any
     liability which any Purchaser may otherwise have.

                                     16

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

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

                                     17
<PAGE>

     liabilities (including legal or other expenses reasonably incurred in
     connection with investigating or defending same) (collectively "Losses")
     to which the Company, and one or more of the Purchasers may be subject in
     such proportion as is appropriate to reflect the relative benefits
     received by the Company and by the Purchasers, respectively, from the
     offering of the Securities; PROVIDED, HOWEVER, that in no case shall any
     Purchaser be responsible for any amount in excess of the purchase
     discount or commission applicable to the Securities purchased by such
     Purchaser hereunder.  If the allocation provided by the immediately
     preceding sentence is unavailable for any reason, the Company and the
     Purchasers shall contribute in such proportion as is appropriate to
     reflect not only such relative benefits but also the relative fault of
     the Company and of the Purchasers, respectively, in connection with the
     statements or omissions which resulted in such Losses as well as any
     other relevant equitable considerations.  For the purpose of this
     paragraph 8(d), benefits received by the Company shall be deemed to be
     equal to the total net proceeds from the offering (before deducting
     expenses) received by each of them, and benefits received by the
     Purchasers shall be deemed to be equal to the total purchase discounts
     and commissions, in each case as set forth on the cover page of the Final
     Memorandum.  Relative fault shall be determined by reference to whether
     any alleged untrue statement or omission relates to information provided
     by the Company or the Purchasers and the parties' relative intent,
     knowledge, access to information and opportunity to correct or prevent
     such untrue statement or omission.  The Company and the Purchasers agree
     that it would not be just and equitable if contribution were determined
     by pro rata allocation or any other method of allocation which does not
     take account of the equitable considerations referred to above.
     Notwithstanding the provisions of this paragraph (d), no person guilty of
     fraudulent misrepresentation (within the meaning of Section 11(f) of the
     Securities Act) shall be entitled to contribution from any person who was
     not guilty of such fraudulent misrepresentation.  The Purchasers'
     respective obligations to contribute pursuant to this paragraph 8(d)
     shall be several in proportion to their respective purchase obligations
     and not joint.  For purposes of this Section 8, each person who controls
     a Purchaser within the meaning of either the Securities Act or the
     Exchange Act and each director, officer, employee and agent of a
     Purchaser shall have the same rights to contribution as such Purchaser,
     and each person who controls the Company within the meaning of either the
     Securities Act or the Exchange Act, each officer of the Company and each
     director of the Company shall have the same rights to contribution as the
     Company, subject in each case to the applicable terms and conditions of
     this paragraph (d).

     9.  DEFAULT BY A PURCHASER.  If any one or more Purchasers shall fail to
purchase and pay for any of the Securities agreed to be purchased by such
Purchaser or Purchasers hereunder on the Closing Date and such failure to
purchase shall constitute a default in the performance of its or their
obligations under this Agreement, the remaining Purchasers shall be obligated
severally to take up and pay for (in the respective proportions which the
amount of Securities set forth opposite their names in Schedule I hereto bears
to the aggregate amount of Securities set forth opposite the names

                                     18
<PAGE>

of all the remaining Purchasers) the Securities which the defaulting Purchaser
or Purchasers agreed but failed to purchase; PROVIDED, HOWEVER, that in the
event that the aggregate amount of Securities which the defaulting Purchaser
or Purchasers agreed but failed to purchase shall exceed 10% of the total
principal amount of Securities that the Purchasers are obligated to purchase
on such Closing Date, the remaining Purchasers shall have the right to
purchase all, but shall not be under any obligation to purchase any, of the
Securities, and if such nondefaulting Purchasers do not purchase all the
Securities to be purchased on such Closing Date, this Agreement will terminate
without liability to any nondefaulting Purchaser or the Company.  In the event
of a default by any Purchaser as set forth in this Section 9, such Closing
Date shall be postponed for such period, not exceeding seven days, as the
Purchasers shall determine in order that the required changes in the Final
Memorandum or in any other documents or arrangements may be effected.  Nothing
contained in this Agreement shall relieve any defaulting Purchaser of its
liability, if any, to the Company and any nondefaulting Purchaser for damages
occasioned by its default hereunder.  As used in this Agreement, the term
"Purchaser" includes any person substituted for a Purchaser under this Section.

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

     11.  REPRESENTATIONS AND INDEMNITIES TO SURVIVE. The respective
agreements, representations, warranties, indemnities and other statements of
the Company or its officers and of the Purchasers set forth in or made
pursuant to this Agreement will remain in full force and effect, regardless of
any investigation made by or on behalf of any Purchaser or the Company or any
of the officers, directors or controlling persons referred to in Section 8
hereof, and will survive delivery of and payment for the Securities.  The
provisions of Sections 7 and 8 hereof shall survive the termination or
cancelation of this Agreement.

     12.  NOTICES.  All communications hereunder will be in writing and
effective only on receipt, and, if sent to the Purchasers, will be mailed,
delivered or telegraphed and confirmed to them, care of Salomon Smith Barney,

                      SELLING RESTRICTIONS FOR OFFERS AND
                        SALES OUTSIDE THE UNITED STATES

     (1)

          (a)  The Securities have not been and will not be registered under
     the Securities Act and may not be offered or sold within the United
     States or to, or for the account or benefit of, U.S. persons except in
     accordance with Regulation S under the Securities Act or pursuant to an
     exemption from the registration requirements of the Securities Act.  Each
     Purchaser represents and agrees that, except as otherwise permitted by
     Section 4(a)(i) of the Agreement to which this is an exhibit, it has
     offered and sold the Securities, and will offer and sell the Securities,
     (i) as part of their distribution at any time and (ii) otherwise until 40
     days after the later of the commencement of the offering and the Closing
     Date, only in accordance with Rule 903 of Regulation S under the
     Securities Act.  Accordingly, each Purchaser represents and agrees that
     neither it, nor any of its affiliates nor any person acting on its or
     their behalf has engaged or will engage in any directed selling efforts
     with respect to the Securities, and that it and they have complied and
     will comply with the offering restrictions requirement of Regulation S.
     Each Purchaser agrees that, at or prior to the confirmation of a sale of
     Securities (other than a sale of Securities pursuant to Section 4(a)(i)
     of the Agreement to which this is an exhibit), it shall have sent to each
     distributor, dealer or person receiving a selling concession, fee or
     other remuneration that purchases Securities from it during the
     restricted period a confirmation or notice to substantially the following
     effect:

                   "The Securities covered hereby have not been registered
          under the U.S. Securities Act of 1933 (the "Securities Act") and may
          not be offered or sold within the United States or to, or for the
          account or benefit of, U.S. persons (i) as part of their
          distribution at any time or (ii) otherwise until 40 days after the
          later of the commencement of the offering and December 11, 1997,
          except in either case in accordance with Regulation S, Rule 144A or
          other exemption from registration under the Securities Act.  Terms
          used above have the meanings given to them by Regulation S."

          (b)  Each Purchaser also represents and agrees that it has not
     entered and will not enter into any contractual arrangement with any
     distributor with respect to the distribution of the Securities, except
     with its affiliates or with the prior written consent of the Company.

          (c)  Terms used in this Section have the meanings given to them by
     Regulation S.

<PAGE>

     (2)  Each Purchaser represents and agrees that (i) it has not offered or
sold, and will not offer or sell, in the United Kingdom, by means of any
document, any Securities other than to persons whose ordinary business it is
to buy or sell shares or debentures, whether as principal or as agent (except
in circumstances which do not constitute an offer to the public within the
meaning of the Companies Act 1985 of Great Britain), (ii) it has complied and
will comply with all applicable provisions of the Financial Services Act of
1986 of the United Kingdom with respect to anything done by it in relation to
the Securities in, from or otherwise involving the United Kingdom, and (iii)
it has only issued or passed on and will only issue or pass on in the United
Kingdom any document received by it in connection with the issue of the
Securities to a person who is of a kind described in Article 9(3) of the
Financial Services Act 1986 (Investment Advertisements) (Exemptions) Order
1988 or is a person to whom the document may otherwise lawfully be issued or
passed on.

     (3)  No action has been or will be taken by the Company or any other
person that would permit the offer or sale of the Securities or the
distribution of the Final Memorandum or any other offering material relating
to the Securities in any jurisdiction where action for that purpose is
required.  The Company shall have no responsibility with respect to the right
of any person to offer or sell Securities or to distribute the Final
Memorandum or any other offering material relating to the Securities in any
jurisdiction.  Accordingly, no Purchaser shall offer or sell any Securities,
or distribute the Final Memorandum or any other offering material relating to
the Securities, in any jurisdiction except in compliance with applicable law.
Each Purchaser shall obtain any consent, approval or authorization required
for it to offer or sell Securities, or to distribute the Final Memorandum or
any other offering material relating to the Securities under the laws or
regulations of any jurisdiction where it proposes to make offers or sales of
Securities, or to distribute the Final Memorandum or any other offering
material relating to the Securities.

                               NOTICE TO INVESTORS

OFFERS AND SALES BY THE INITIAL PURCHASERS

     The Notes have not been registered under the Securities Act and may not
be offered or sold in the United States or to, or for the account or benefit
of, U.S. persons except in accordance with an applicable exemption from the
registration requirements thereof.  Accordingly, the Notes are being offered
and sold only (i) in the United States to QIBs under Rule 144A under the
Securities Act and (ii) outside the United States to non-U.S. persons
("foreign purchasers") in reliance upon Regulation S under the Securities Act.
 Each foreign purchaser that is a purchaser of Notes from the Initial
Purchasers (an "Initial Foreign Purchaser") will be required to sign a
certificate in the form provided by the Initial Purchasers.

INVESTOR REPRESENTATIONS AND RESTRICTIONS ON RESALE

     Each purchaser of the Notes will be deemed to have represented and agreed
as follows:

     (1) it is acquiring the Notes for its own account or for an account with
respect to which it exercises sole investment discretion, and that it or such
account is a QIB or a foreign purchaser outside the United States;

     (2) it acknowledges that the Notes have not been registered under the
Securities Act and may not be sold except as permitted below;

     (3) it understands and agrees (x) that such Notes are being offered only
in a transaction not involving any public offering within the meaning of the
Securities Act, and (y) that (A) if within two years after the date of
original issuance of the Notes or if within three months after it ceases to be
an affiliate (within the meaning of Rule 144 under the Securities Act) of the
Company, it decides to resell, pledge or otherwise transfer such Notes on
which the legend set forth below appears, such Notes may be resold, pledged or
transferred only (i) to the Company, (ii) so long as such security is eligible
for resale pursuant to Rule 144A, to a person whom the seller reasonably
believes is a QIB that purchases for its own account or for the account of a
QIB to whom notice is given that the resale, pledge or transfer is being made
in reliance on Rule 144A (as indicated by the box checked by the transferor on
the Certificate of Transfer on the reverse of the Note if such Note is not in
book-entry form), (iii) in an offshore transaction in accordance with
Regulation S (as indicated by the box checked by the transferor on the
Certificate of Transfer on the reverse of the Note if such Note is not in
book-entry form), (iv) to an Institutional Accredited Investor, as defined in
Rule 501(a)(1), (2), (3) or (7) under the Securities Act (as indicated by the
box checked by the transferor on the Certificate of Transfer on the reverse of
the Note if such Note is not in book-entry form), that is acquiring the Notes
for investment purposes and not for distribution, and a certificate which may
be obtained from the Company or the Trustee is delivered by the transferee to
the Company and the Trustee, (v) pursuant to an exemption from registration
under the Securities Act provided by

<PAGE>

Rule 144 (if applicable) under the Securities Act or (vi) pursuant to an
effective registration statement under the Securities Act, in each case in
accordance with any applicable securities laws of any state of the United
States, (B) the purchaser will, and each subsequent holder is required to,
notify any purchaser of Notes from it of the resale restrictions referred to
in (A) above, if then applicable, and (C) with respect to any transfer of
Notes by an Institutional Accredited Investor, such holder will deliver to the
Company and the Trustee such certificates and other information as they may
reasonably require to confirm that the transfer by it complies with the
foregoing restrictions;

     (4) it understands that the notification requirement referred to in (3)
above will be satisfied, in the case only of transfers by physical delivery of
certificated Notes other than a Global Note, by virtue of the fact that the
following legend will be placed on the Notes unless otherwise agreed by the
Company:

          "THIS SECURITY HAS NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF
     1933, AS AMENDED (THE "SECURITIES ACT").  THE HOLDER HEREOF, BY
     PURCHASING THIS SECURITY, AGREES FOR THE BENEFIT OF THE COMPANY THAT THIS
     SECURITY MAY NOT BE RESOLD, PLEDGED OR OTHERWISE TRANSFERRED (X) PRIOR TO
     THE SECOND ANNIVERSARY OF THE ISSUANCE HEREOF (OR A PREDECESSOR SECURITY

      Securities New Securities equal in principal amount to the

      (e)  The Initial Purchasers and the Company acknowledge that,

      Annex C hereto in the underwriting or plan of distribution section 
      of the Prospectus forming a part of the Exchange Offer Registration 
      Statement, and include the information set forth in Annex D hereto 
      in the Letter of Transmittal delivered pursuant to the Registered 
      Exchange Offer; and
      
         (ii)   use its best efforts to keep the Exchange Offer 
      Registration Statement continuously effective under the Act during 
      the Exchange Offer Registration Period for delivery by Exchanging 
      Dealers in connection with sales of New Securities received 
      pursuant to the Registered Exchange Offer, as contemplated by 
      Section 4(h) below.

      (f) In the event that any Initial Purchaser determines that it is not 
   eligible to participate in the Registered Exchange Offer with respect to 
   the exchange of Securities constituting any portion of an unsold 
   allotment, at the request of such Initial Purchaser, the Company shall 
   issue and deliver to such Initial Purchaser or the party purchasing New 
   Securities registered under a Shelf Registration Statement as 
   contemplated by Section 3 hereof from such Initial Purchaser, in 
   exchange for such Securities, a like principal amount of New Securities. 
   The Company shall seek to cause the CUSIP Service Bureau to issue the 
   same CUSIP number for such New Securities as for New Securities issued 
   pursuant to the Registered Exchange Offer.

   3.  SHELF REGISTRATION.  If, (i) because of any change in law or 
applicable interpretations thereof by the Commission's staff, the Company 
determines upon advice of its outside counsel that it is not permitted to 
effect the Registered Exchange Offer as contemplated by Section 2 hereof, or 
(ii) if for any other reason the Registered Exchange Offer is not declared 
effective within 180 days following the date of original issuance of the 
Securities, or (iii) if any Initial Purchaser so requests with respect to 
Securities held by it constituting any portion of an allotment remaining 
unsold after 30 days following the date hereof, or (iv) in the case of any 
Initial Purchaser that participates in the Registered Exchange Offer or 
acquires New Securities pursuant to Section 2(f) hereof, such Initial 
Purchaser does not receive freely tradeable New Securities in exchange for 
Securities constituting any portion of an unsold allotment (it being 
understood that, for purposes of this Section 3, (x) the requirement that an 
Initial Purchaser deliver a Prospectus containing the information required by 
Items 507 and/or 508 of Regulation S-K under the Act in connection with sales 
of New Securities acquired in exchange for such Securities shall result in 
such New Securities being not "freely tradeable" but (y) the requirement that 
an Exchanging Dealer deliver a Prospectus in connection with sales of New 
Securities acquired in the Registered Exchange Offer in exchange for 
Securities acquired as a result of market-making activities or other trading 
activities shall not result in such New Securities being not "freely 
tradeable"), the following provisions shall apply:

      (a) The Company shall, at its cost, as promptly as practicable, file 
   with the Commission and thereafter shall use its best efforts to cause 
   to be declared effective by the 210th day after the original date of 
   issuance of the Securities under the Act a Shelf Registration Statement 
   relating to the offer and sale of the Securities or the New Securities, 
   as applicable, by the Holders from time to time in accordance with the 
   methods of distribution set forth in such Shelf Registration Statement 
   and Rule 415 under the Act; provided that with respect to New Securities 
   received by an Initial Purchaser in exchange for Securities constituting 
   any portion of an unsold allotment, the Company may, if permitted by 
   current interpretations by the Commission's staff, file a post-effective 
   amendment to the Exchange Offer Registration Statement containing the 
   information required by Regulation S-K Items 507 and/or 508, as 
   applicable, in satisfaction of its obligations under this paragraph (a) 
   with respect thereto, and any such Exchange Offer Registration 
   Statement, as so amended, shall be referred to herein as, and governed 
   by the provisions herein applicable to, a Shelf Registration Statement; 
   PROVIDED, FURTHER, that no Holder (other than an Initial Purchaser) 
   shall be entitled to have the Securities held by it covered by such 
   Shelf Registration Statement unless such Holder agrees in writing to be 
   bound by all the provisions of this Agreement applicable to such Holder 
   as provided in a written notice and questionnaire delivered to all 
   Holders (including the Initial Purchasers) notifying such Holders that a 
   Shelf Registration Statement will be filed by the Company, requesting 
   such information with respect to the Holders as required to be disclosed 
   by the Shelf Registration Statement and setting forth a deadline for 
   response therein (which in no event shall be less than 30 calendar days).

      (b) The Company shall use its best efforts to keep the Shelf 
   Registration Statement continuously effective in order to permit the 
   Prospectus forming part thereof to 

                                        6
<PAGE>

   be lawfully delivered by Holders until the earliest of (x) the second 
   anniversary of the date of original issuance of the Securities (or the 
   first anniversary of the effective date if such Shelf Registration 
   Statement is filed at the request of the Initial Purchasers), (y) the 
   time when the Securities registered thereunder can be sold by 
   non-affiliates pursuant to Rule 144 under the Securities Act without 
   limitation under clauses (c), (e), (f) and (h) of Rule 144, or (z) such 
   time as all the Securities registered thereunder have been sold (in any 
   such case, such period being called the "Shelf Registration Period").  
   During any consecutive 365-day period, the Company will have the ability 
   to suspend the availability of the Shelf Registration Statement for up 
   to two periods of up to 45 consecutive days, but no more than an 
   aggregate of 60 days during any 365-day period.  The Company shall be 
   deemed not to have used its best efforts to keep the Shelf Registration 
   Statement effective during the requisite period if it voluntarily takes 
   any action that would result in Holders of Securities covered thereby 
   not being able to offer and sell such Securities during that period, 
   unless (i) such action is required by applicable law, or (ii) upon the 
   occurrence of any event contemplated by paragraph 4(c)(2)(iii) below, 
   such action is taken by the Company in good faith and for valid business 
   reasons (not including avoidance of the Company's obligations 
   hereunder), so long as the Company promptly thereafter complies with the 
   requirements of Section 4(k) hereof, if applicable, if the Company has 
   determined in good faith that there are no material legal or commercial 
   impediments in so doing.

   4.  REGISTRATION PROCEDURES.  In connection with any Shelf Registration 
Statement and, to the extent applicable, any Exchange Offer Registration 
Statement, the following provisions shall apply:

      (a) The Company shall (i) furnish to each Initial Purchaser, prior to 
   the filing thereof with the Commission, a copy of any Shelf Registration 
   Statement and any Exchange Offer Registration Statement, and each 
   amendment thereof and each amendment or supplement, if any, to the 
   Prospectus included therein, (ii) in the event that an Initial Purchaser 
   (with respect to any portion of an unsold allotment from the original 
   offering) is participating in the Registration Statement, use its best 
   efforts to reflect in each such document, when so filed with the 
   Commission, such comments as the Initial Purchasers reasonably may 
   propose and (iii) include the names of the Holders who propose to sell 
   Securities pursuant to the Shelf Registration Statement, as selling 
   securityholders.

   contrary, the Company shall ensure that (other than with respect to 
   information required to be supplied by the selling Holders pursuant to 
   this Agreement) (i) any Registration Statement and any amendment thereto 
   and any Prospectus forming part thereof and any amendment or supplement 
   thereto complies in all material respects with the applicable 
   requirements of the Act and the rules and regulations of the Commission 
   thereunder, (ii) any Registration Statement and any amendment thereto 
   does not, when it becomes effective, contain an untrue statement of a 
   material fact or omit to state a material fact required to be stated 
   therein or necessary to make the statements therein not misleading and

                                       7

   Prospectus, does not contain, as of the date of such prospectus or 
   amendment or supplement, any untrue statement of a material fact or omit

      been filed with the Commission and when the Registration Statement 
      or any post-effective amendment thereto has become effective; and
      
         (ii) of any request by the Commission for amendments or 
      supplements to the Registration Statement or the Prospectus 
      included therein or for additional information.

   (2) The Company shall advise the Initial Purchasers in writing and, in 
the case of a Shelf Registration Statement, the Holders of Securities covered 
thereby, and, in the case of an Exchange Offer Registration Statement, any 
Exchanging Dealer which has provided in writing to the Company a telephone or 
facsimile number and address for notices:

         (i)   of the issuance by the Commission of any stop order 
      suspending the effectiveness of the Registration Statement or the 
      initiation of any proceedings for that purpose;
      
         (ii)  of the receipt by the Company of any notification with 
      respect to the suspension of the qualification of the Securities 
      included therein for sale in any jurisdiction or the initiation or

         (iii) of the happening of any event that requires the Company to 
      make any changes in the Registration Statement or the Prospectus so 
      that, as of such date, the statements therein do not contain an 
      untrue statement of a material fact or omit to state a material 
      fact required to be stated therein or necessary to make the 
      statements therein (in the case of the Prospectus, in light of the 
      circumstances under which they were made) not misleading (which 
      written notice shall be accompanied by an instruction to suspend 
      the use of the Prospectus until the requisite changes have been 
      made and which need not provide any detail as to the nature of such 
      event).

      (d) The Company shall use reasonable commercial efforts to obtain the 
   withdrawal of any order suspending the effectiveness of any Registration 
   Statement at the earliest possible time.

      (h) The Company shall, during the Exchange Offer Registration Period, 
   promptly deliver to each Exchanging Dealer, without charge, as many 
   copies of the Prospectus included in such Exchange Offer Registration 
   Statement and any amendment or supplement thereto as such Exchanging 
   Dealer may reasonably request for delivery by such Exchanging Dealer in 
   connection with a sale of New Securities received by it pursuant to the 
   Registered Exchange Offer; and the Company consents to the use of the 
   Prospectus or any amendment or supplement thereto by any such Exchanging 
   Dealer, as aforesaid.
   
      (i) Prior to the Registered Exchange Offer or any other offering of 
   Securities pursuant to any Registration Statement, the Company shall 
   register or qualify or cooperate with the Holders of the Securities 
   included therein and their respective counsel in connection with the 
   registration or qualification of such Securities for offer and sale 
   under the securities or blue sky laws of such states of the United 
   States as any such Holders reasonably request in writing and do any and 
   all other acts or things necessary or advisable to enable the offer and 
   sale in such jurisdictions of the Securities covered by such 
   Registration Statement; PROVIDED, HOWEVER, that the Company will not be 
   required to qualify generally to do business in any jurisdiction where 
   it is not then so qualified or to take any action which would subject it 
   to general service of process or to taxation in any such jurisdiction 
   where it is not then so subject.

                                           9

      (j) The Company shall cooperate with the Holders of Securities to 
   facilitate the timely preparation and delivery of certificates 
   representing Securities to be sold pursuant to any Registration 
   Statement free of any restrictive legends and in such denominations and 
   registered in such names as Holders may request prior to sales of 
   Securities pursuant to such Registration Statement.
   
      (k) Upon the occurrence of any event contemplated by paragraph (c) 
   above during the period for which the Company is required to maintain an 
   effective Registration Statement, the Company shall promptly prepare a 
   post-effective amendment to any Registration Statement or an amendment 
   or supplement to the related Prospectus or file any other required 
   document so that, as thereafter delivered to purchasers of the 
   Securities included therein, the Prospectus will not include an untrue 
   statement of a material fact or omit to state any material fact 
   necessary to make the statements therein, in the light of the 
   circumstances under which they were made, not misleading.  If the 
   Company notifies the Initial Purchasers or the Holders in accordance 
   with paragraphs (i) through (iii) of Section 4(c)(2) above to suspend 
   the use of the Prospectus until the requisite changes to the Prospectus 
   have been made, then the Initial Purchasers and the Holders shall 
   suspend use of such prospectus.
   
      (l) Not later than the effective date of any such Registration 
   Statement hereunder, the Company shall provide a CUSIP number for the 
   Securities or New Securities, as the case may be, registered under such 
   Registration Statement, and provide the applicable trustee with printed 
   certificates for such Securities or New Securities, in a form eligible 
   for deposit with The Depository Trust Company.
   
      (m) The Company will comply with all rules and regulations of the 
   Commission to the extent and so long as they are applicable to the 
   Registration Statement and will make generally available to its security 
   holders (or otherwise provide in accordance with Section 11(a) of the 
   Securities Act) an earnings statement satisfying the provisions of 
   Section 11(a) of the Securities Act, no later than 45 days after the end 
   of a 12-month period (or 90 days, if such period is a fiscal year) 
   beginning with the first month of the Company's first fiscal quarter 
   commencing after the effective date of the Registration Statement, which 
   statement shall cover such 12-month period.
   
      (n) The Company shall cause the Indenture or the New Securities 
   Indenture, as the case may be, to be qualified under the Trust Indenture 
   Act in a timely manner, containing such changes, if any, as shall be 
   necessary for such qualification.  In the event that such qualification 
   would require the appointment of a new trustee under the Indenture, the 
   Company shall appoint a new trustee thereunder pursuant to the 
   applicable provisions of the Indenture.
   
      (o) The Company may require each Holder of Securities to be sold 
   pursuant to any Shelf Registration Statement to furnish to the Company 
   such information regarding the 
   
                                      10
<PAGE>

   Holder and the distribution of such Securities as the Company may from 
   time to time reasonably require for inclusion in such Registration 
   Statement, and the Company may exclude from such registration the 
   Securities of any Holder that fails to furnish such information within a 
   reasonable time after receiving such request.
   
      (p) The Company shall, if requested, promptly incorporate in a 
   Prospectus supplement or post-effective amendment to a Shelf 
   Registration Statement, such information as the Majority Holders 
   reasonably agree should be included therein and shall make all required 
   filings of such Prospectus supplement or post-effective amendment as 
   soon as notified of the matters to be incorporated in such Prospectus 
   supplement or post-effective amendment.
   
      (q) In the case of any Shelf Registration Statement, the Company 
   shall enter into such agreements and shall use reasonable commercial 
   efforts to take all other steps in order to expedite or facilitate the 
   registration or the disposition of the Securities.
   
      (r) In the case of any Shelf Registration Statement, the Company 
   shall (i) make reasonably available for inspection by the Holders of the 
   Securities to be registered thereunder, and any attorney, accountant or 
   other agent retained by the Holders, all relevant financial and other 
   records, pertinent corporate documents and properties of the Company; 
   and (ii) cause the Company's officers, directors, employees, accountants 
   and auditors to supply all relevant information reasonably requested by 
   the Holders or any such attorney, accountant or agent in connection with 
   any such Registration Statement, in each case as shall be reasonably 
   necessary to enable such persons to conduct a reasonable investigation 
   within the meaning of Section 11 of the Securities Act; provided, 
   however, that any information that is designated in writing by the 
   Company, in good faith, as confidential at the time of delivery of such 
   information shall be kept confidential by the Holders or any such 
   attorney, accountant or agent, unless such disclosure is made in 
   connection with a court proceeding or required by law, or such 
   information becomes available to the public generally or through a third 
   party without an accompanying obligation of confidentiality and that the 
   foregoing inspection and information gathering (i) shall be coordinated 
   on behalf of the Initial Purchasers by you and on behalf of the other 
   parties, by one counsel (the "Designated Counsel") designated by the 
   Holders of a majority in principal amount of the Securities covered by 
   the Registration Statement and (ii) shall not be available for any such 
   Holder that is a competitor of the Company.
   
      (s) In the case of any Exchange Offer Registration Statement, the 
   Company shall (i) make reasonably available for inspection by the 
   Initial Purchasers, and any attorney, accountant or other agent retained 
   by the Initial Purchasers, all relevant financial and other records, 
   pertinent corporate documents and properties of the Company; and (ii) 
   cause the Company's officers, directors, employees, accountants and 
   auditors to supply all relevant information reasonably requested by the 
   Initial Purchasers or any such attorney, accountant or agent in 
   connection with any such Registration Statement, in each case as shall 
   be 
   
                                         11
<PAGE>

   reasonably necessary to enable such persons to conduct a reasonable 
   investigation within the meaning of Section 11 of the Securities Act; 
   PROVIDED, HOWEVER, that any information that is designated in writing by 
   the Company, in good faith, as confidential at the time of delivery of 
   such information shall be kept confidential by the Initial Purchasers or 
   any such attorney, accountant or agent, unless such disclosure is made 
   in connection with a court proceeding or required by law, or such 
   information becomes available to the public generally or through a third 
   party without an accompanying obligation of confidentiality and that the 
   foregoing inspection and information gathering (i) shall be coordinated 
   on behalf of the Initial Purchasers by you and on behalf of the other 
   parties by one counsel (the "Designated Counsel") designated by the 
   Holders of a majority in principal amount of the Securities covered by 
   the Registration Statement and (ii) shall not be available for any such 
   Holder that is a competitor of the Company.
   
      (t) The Company, if requested by the Designated Counsel, shall cause 
   (i) its counsel to deliver an opinion and updates thereof relating to 
   the Securities in customary form addressed to such Holders, and dated, 
   in the case of the initial opinion, the effective date of such 
   Registration Statement (it being agreed that the matters to be covered 
   by such opinion shall include, without limitation, the due incorporation 
   and good standing in its jurisdiction of incorporation of the Company 
   and its Significant Subsidiaries (as defined in the Act); the due 
   authorization, execution, authentication and issuance, and the validity 
   and enforceability, of the applicable Securities; the absence of 
   material legal or governmental proceedings involving the Company and its 
   subsidiaries; the absence of governmental approvals required to be 
   obtained in connection with the Registration Statement, or the offering 
   and sale of the applicable Securities; the compliance as to form of such 
   Registration Statement and any documents incorporated by reference 
   therein and of the Indenture with the requirements of the Securities Act 
   and the Trust Indenture Act, respectively; and, as of the date of the 
   opinion and as of the effective date of the Registration Statement or 
   most recent post-effective amendment thereto, as the case may be, to 
   confirm, in customary form and substance of such counsel, the absence 
   from such Registration Statement and the prospectus included therein (in 
   each case other than the financial statements and other financial 
   information contained therein, as to which such counsel need express no 
   opinion), as then amended or supplemented, and from any documents 
   incorporated by reference therein, of an untrue statement of a material 
   fact or the omission to state therein a material fact required to be 
   stated therein or necessary to make the statements therein not 
   misleading (in the case of any such documents, in the light of the 
   circumstances existing at the time that such documents were filed with 
   the Commission under the Exchange Act), (ii) its officers to execute and 
   deliver all customary documents and certificates and updates thereof 
   requested by the Designated Counsel and (iii) its independent public 
   accountants and the independent public accountants with respect to any 
   other entity for which financial information is provided in the 
   Registration Statement to provide to the selling Holders of the 
   applicable Securities a comfort letter in customary form and covering 
   matters of the type customarily covered in comfort letters in connection 
   with primary underwritten offerings, subject to receipt of 
   
                                        12
<PAGE>

   appropriate documentation as contemplated, and only if permitted, by 
   Statement of Auditing Standards No. 72.
   
       (v) The Company will use its best efforts to continue to have the 
   Securities rated by the rating agencies that rated the Securities in 
   connection with the sale to the Initial Purchasers and, at the request 
   of any Holder, confirm to such Holder the current rating of the 
   Securities at the time of such request.
   
       (w) The Company shall use reasonable commercial efforts to take all 
   other steps necessary to effect the registration of the Securities 
   covered by the Registration Statement contemplated hereby.
   
   5. REGISTRATION EXPENSES.  The Company shall bear all expenses incurred in 
connection with the performance of its obligations under Sections 2, 3 and 4 
hereof, whether or not the Shelf Registration Statement is filed or becomes 
effective, and shall bear or reimburse the Holders of the Securities covered 
by the Shelf Registration Statement for the reasonable fees and disbursements 
of the Designated Counsel, if any, and, in the case of any Exchange Offer 
Registration Statement, will reimburse the Initial Purchasers for the 
reasonable fees and disbursements of the Designated Counsel, if any, acting 
in connection therewith.

   6. INDEMNIFICATION AND CONTRIBUTION.  (a)  In connection with any 
Registration Statement, the Company agrees to indemnify and hold harmless 
each Holder of securities covered thereby (including each Initial Purchaser 
and, with respect to any Prospectus delivery as contemplated in Section 4(h) 
hereof, each Exchanging Dealer), and each person, if any, who controls any 
such Holder within the meaning of either the Act or the Exchange Act (each 
Holder and such controlling persons are referred to collectively as the 
"Indemnified Parties") from and against any and all losses, claims, damages 
or liabilities, joint or several, or any actions in respect thereof 
(including but not limited to, any losses claims, damages, liabilities or 
actions relating to purchases and sales of the Securities) to which each 
Indemnified Party becomes subject under the Act, the Exchange Act or 
otherwise, insofar as such losses, claims, damages or liabilities (or actions 
in respect thereof) arise out of or are based upon any untrue statement or 
alleged untrue statement of a material fact contained in the Registration 
Statement as originally filed or in any amendment thereof, or in any 
preliminary Prospectus or Prospectus, or in any amendment thereof or 
supplement thereto, or arise out of or are based upon the omission or alleged 
omission to state therein a material fact required to be stated therein or 
necessary to make the statements therein not misleading, and subject to 
subsection (c), reimburse, as incurred, the Indemnified Parties for any legal 
or other expenses reasonably incurred by them in connection with 
investigating or defending any such loss, claim, damage, liability or action 
in respect thereof; PROVIDED, HOWEVER, that (i) the Company will not be 
liable in any such case to the extent that such loss, claim, damage or 
liability arises out of or is based upon (x) the use of any prospectus in 
violation of the last sentence of Section 4(k), or (y) any such untrue 
statement or alleged untrue statement or omission or alleged omission made in 
the Shelf Registration Statement or prospectus or in any amendment or 
supplement thereto or in any preliminary prospectus relating to the Shelf 
Registration in reliance upon and in conformity with 

                                    13
<PAGE>

written information pertaining to such Holder and furnished to the Company by 
or on behalf of such Holder specifically for inclusion therein and (ii) with 
respect to any untrue statement or omission or alleged untrue statement or 
omission made in any preliminary prospectus relating to the Registration 
Statement, the indemnity agreement contained in this subsection (a) shall not 
inure to the benefit of any Holder from whom the person asserting any such 
losses, claims, damages or liabilities purchased the Securities concerned, to 
the extent that a prospectus relating to such Securities was required to be 
delivered by such Holder under the Securities Act in connection with such 
purchase and any such loss, claim, damage or liability of such Holder results 
from the fact that there was not sent or given to such person, at or prior to 
the written confirmation of the sale of such Securities to such person, a 
copy of the final prospectus if the Company had previously furnished copies 
thereof in sufficient quantity to such Holder; PROVIDED FURTHER, HOWEVER, 
that this indemnity agreement will be in addition to any liability which the 
Company may otherwise have to such Indemnified Party.

      (b) Each Holder of Securities covered by a Shelf Registration Statement 
   severally and not jointly, will indemnify and hold harmless the Company and 
   each person who controls the Company within the meaning of either the Act or 
   the Exchange Act to the same extent as the foregoing indemnity from the 
   Company to each such Holder, but only with reference to written information 
   relating to such Holder furnished to the Company by or on behalf of such 
   Holder specifically for inclusion in the documents referred to in the 
   foregoing indemnity.  This indemnity agreement will be in addition to any 
   liability which any such Holder may otherwise have.
   
      (c) Promptly after receipt by an indemnified party under this Section 
   6 of notice of the commencement of any action or proceeding (including a 
   governmental investigation), such indemnified party will, if a claim in 
   respect thereof is to be made against the indemnifying party under this 
   Section 6, notify the indemnifying party in writing of the commencement 
   thereof; but the failure so to notify the indemnifying party will not, 
   in any event, relieve the indemnifying party from any obligations to any 
   indemnified party other than the indemnification obligation provided in 
   subsections (a) or (b) above.  In case any such action is brought 
   against any indemnified party, and it notifies the indemnifying party of 
   the commencement thereof, the indemnifying party will be entitled to 
   participate therein and, to the extent that it may wish, jointly with 
   any other indemnifying party similarly notified, to assume the defense 
   thereof, with counsel reasonably satisfactory to such indemnified party 
   (who shall not, except with the consent of the indemnified party, be 
   counsel to the indemnifying party if the representation of both such 
   parties by the same counsel would constitute a conflict of interest), 
   and after notice from the indemnifying party to such indemnified party 
   of its election so to assume the defense thereof the indemnifying party 
   will not be liable to such indemnified party under this Section 6 for 
   any legal or other expenses, other than reasonable costs of 
   investigation, subsequently incurred by such indemnified party in 
   connection with the defense thereof.  No indemnifying party shall, 
   without the prior written consent of the indemnified party, effect any 
   settlement of any pending or threatened action in respect of which any 
   indemnified party is or could have been a party and indemnity could have 
   been sought hereunder by such indemnified party unless 

                                          14
<PAGE>

   such settlement includes an unconditional release of such indemnified party 
   from all liability on any claims that are the subject matter of such action.
   
      (d) In the event that the indemnity provided in (a) or (b) of this 
   Section 6 is unavailable to or insufficient to hold harmless an 
   indemnified party for any reason, then each applicable indemnifying 
   party, shall contribute to the amount paid or payable by such 
   indemnified party as a result of the losses, claims, damages or 
   liabilities (or actions in respect thereof) referred to in subsections 
   (a) or (b) above (i) in such proportion as is appropriate to reflect the 
   relative benefits received by the Company from the offering and sale of 
   the Securities, on the one hand, and a Holder with respect to the sale 
   by such Holder of Securities or New Securities, on the other hand; 
   PROVIDED, HOWEVER, that in no case shall any Initial Purchaser or any 
   subsequent Holder of any Security or New Security be responsible, in the 
   aggregate, for any amount in excess of the amount by which the net 
   proceeds received by such Holders from the sale of the Securities 
   pursuant to the Shelf Registration Statement exceeds the amount of 
   damages which such Holders have otherwise been required to pay by reason 
   of such untrue or alleged untrue statement or omission or alleged 
   omission.  If the allocation provided by the immediately preceding 
   sentence is unavailable for any reason, the indemnifying party and the 
   indemnified party shall contribute in such proportion as is appropriate 
   to reflect not only such relative benefits but also the relative fault 
   of such indemnifying party, on the one hand, and such indemnified party, 
   on the other hand, in connection with the statements or omissions which 
   resulted in such losses, claims, damages or liabilities (or actions in 
   respect thereof) as well as any other relevant equitable considerations. 
   Relative fault shall be determined by reference to, among other things, 
   whether the untrue or alleged untrue statement of a material fact or the 
   omission or alleged omission to state a material fact relates to 
   information provided by the indemnifying party, on the one hand or by 
   the indemnified party, on the other hand and the parties' relative 
   intent, knowledge, access to information and opportunity to correct or 
   prevent such statement or omission.  The amount paid by an indemnified 
   party as a result of the losses, claims, damages or liabilities referred 
   to in the first sentence of this subsection (d) shall be deemed to 
   include any legal or other expenses reasonably incurred by such 
   indemnified party in connection with investigating or defending any 
   action or claim which is the subject of this subsection (d).  
   Notwithstanding the provisions of this paragraph (d), no person guilty 
   of fraudulent misrepresentation (within the meaning of Section 11(f) of 
   the Act) shall be entitled to contribution from any person who was not 
   guilty of such fraudulent misrepresentation.  For purposes of this 
   Section 6, each person, if any, who controls such Indemnified Party 
   within the meaning of either the Act or the Exchange Act shall have the 
   same rights to contribution as such indemnified party, and each person, 
   if any, who controls the Company within the meaning of either the Act or 
   the Exchange Act shall have the same rights to contribution as the 
   Company.
   
      (e) The agreements contained in this Section 6 will survive the sale 
   by a Holder of Securities covered by a Registration Statement and shall 
   remain in full force and effect, 
   
                                            15
<PAGE>

   regardless of any termination or cancelation of this Agreement or any 
   investigation made by or on behalf of any indemnified party.
   
   7.  RULES 144 AND 144A.  The Company shall use its best efforts to file 
the reports required to be filed by it under the Securities Act and the 
Exchange Act in a timely manner and, if at any time the Company is not 
required to file such reports, it will, upon the request of any Holder of 
Securities, make publicly available other information so long as necessary to 
permit sales of their Securities pursuant to Rules 144 and 144A.  The Company 
covenants that, if in the event the Company is no longer subject to Sections 
13 or 15(d) of the Exchange Act, it will take such further action as any 
Holder of Securities may reasonably request, all to the extent required from 
time to time to enable such Holder to sell Securities without registration 
under the Securities Act within the limitation of the exemptions provided by 
Rules 144 and 144A (including the requirements of Rule 144A(d)(4)).  The 
Company will provide a copy of this Agreement to prospective purchasers of 
Securities identified to the Company by the Initial Purchasers upon request.  
Notwithstanding the foregoing, nothing in this Section 7 shall be deemed to 
require the Company to register any of its Securities pursuant to the 
Exchange Act.

   8.  ADDITIONAL INTEREST UNDER CERTAIN CIRCUMSTANCES.  (a)  Interest in 
addition to the stated interest (the "Additional Interest") with respect to the 
Securities shall be assessed as follows if any of the following events occur 
(each such event in clauses (i) through (iii) below being herein called a 
"Registration Default"):

         (i)   by the 150th day following the date of original issuance 
      of the Securities, the Exchange Offer Registration Statement is not 
      filed with the Commission;
      
         (ii)  by the 180th day following the date of original issuance 
      of the Securities, neither the Exchange Offer Registration 
      Statement is declared effective nor (if the Exchange Offer is not 
      permitted as described above) the Shelf Registration Statement is 
      filed with the Commission; or
      
         (iii) by the 210th day following the date of original issuance 
      of the Securities, the Exchange Offer is not consummated or the 
      Shelf Registration Statement is not declared effective with respect 
      thereto,
   
Additional Interest shall accrue on the Securities over and above the 
interest set forth in the title of the Securities from and including the date 
on which any such Registration Default shall occur, to but excluding the date 
on which all such Registration Defaults have been cured, at a rate of 0.25% 
per annum of the principal amount of such Securities for each Registration 
Default.

      (b) The aggregate amount of Additional Interest payable pursuant to the 
   above provisions will in no event exceed 0.25% per annum of the principal 
   amount of the Securities which, except as otherwise provided herein, shall be
   the sole and exclusive remedy for such 

                                       16
<PAGE>

   Registration Default.  Upon (x) the filing of the Exchange Offer Registration
   Statement after the 150-day period described in clause (i) of subsection (a),
   (y) the effectiveness of the Exchange Offer Registration Statement or the 
   filing of the Shelf Registration Statement after the 180-day period described
   in clause (ii) of subsection (a) or (z) the consummation of the Exchange 
   Offer for such Securities or the effectiveness of a Shelf Registration 
   Statement, as the case may be, after the 210-day period described in clause 
   (iii) of subsection (a), the Additional Interest payable on such Securities 
   as a result of the applicable Registration Default will cease to accrue.  For
   purposes of the preceding sentence, the curing of a Registration Default by 
   the means described in clause (y) of this subsection shall constitute a cure 
   of the Registration Defaults described in clauses (i) and (ii) of subsection 
   (a), and the curing of a Registration Default by the means described in 
   clause (z) of this subsection shall constitute a cure of the Registration 
   Defaults described in clauses (i), (ii) and (iii) of subsection (a).
   
      (c) In the event that a Shelf Registration Statement is declared 
   effective, if the Company fails to keep such Registration Statement 
   continuously effective (except as permitted under Section 3(b)) for the Shelf
   Registration Period, then from such time as the Shelf Registration Statement 
   is no longer effective until the earlier of

         (i)  the date that the Shelf Registration Statement is again 
      deemed effective and
      
         (ii) the date that is the earliest of (x) the second anniversary 
      of the date of original issuance of the Securities (or until the 
      first anniversary of the effective date if the Shelf Registration 
      Statement is filed at the request of the Initial Purchasers), (y) 
      the time when the Securities registered thereunder can be sold by 
      non-affiliates pursuant to Rule 144 under the Securities Act 
      without any limitation under clauses (c), (e), (f) and (h) of Rule 
      144, or (z) the date as of which all such Securities are sold 
      pursuant to the Shelf Registration Statement,

Additional Interest shall accrue at a rate per annum equal to 0.25% of the 
principal amount of the Securities which, except as otherwise provided herein, 
shall be the sole and exclusive remedy for such Registration Default.

      (d) Any amounts of Additional Interest due pursuant to clause (a)(i), 
   (a)(ii), (a)(iii) or (c) of this Section 8 will be payable in cash 
   semiannually in arrears on the regular interest payment dates with respect to
   the Securities. The amount of Additional Interest will be determined by 
   multiplying the applicable Additional Interest rate by the principal amount 
   of the Securities, multiplied by a fraction, the numerator of which is the 
   number of days such Additional Interest rate was applicable during such 
   period (determined on the basis of a 360-day year comprised of twelve 30-day
   months), and the denominator of which is 360.

                                         17

     (e) Notwithstanding anything to the contrary contained in this 
Agreement, it is hereby acknowledged and agreed that the Company will 
have no other liabilities for monetary damages to the Initial Purchasers 
or any Holder for any breaches, failures to comply or violations by it 
of Sections 3 and 4 hereof; provided, however, that in the event the 
Company breaches, fails to comply with or violates certain provisions of 
this Agreement, the holders shall be entitled to, and the Company shall 
not oppose the granting of, equitable relief, including injunction and 
specific performance.

     9. MISCELLANEOUS.

     (a) NO INCONSISTENT AGREEMENTS.  The Company has not, as of the 
date hereof, entered into, nor shall it, on or after the date hereof, 
enter into, any agreement with respect to its Securities that is 
inconsistent with the rights granted to the Holders herein or otherwise 
conflicts with the provisions hereof.

     (b) AMENDMENTS AND WAIVERS.  The provisions of this Agreement, 
including the provisions of this sentence, may not be amended, 
qualified, modified or supplemented, and waivers or consents to 
departures from the provisions hereof may not be given, unless the 
Company has obtained the written consent of the Holders of at least a 
majority of the then outstanding aggregate principal amount of 
Securities (or, after the consummation of any Exchange Offer in 
accordance with Section 2 hereof, of New Securities); PROVIDED that, 
with respect to any matter that directly or indirectly affects the 
rights of any Initial Purchaser hereunder, the Company shall obtain the 
written consent of each such Initial Purchaser against which such 
amendment, qualification, supplement, waiver or consent is to be 
effective.  Notwithstanding the foregoing (except the foregoing 
proviso), a waiver or consent to departure from the provisions hereof 
with respect to a matter that relates exclusively to the rights of 
Holders whose Securities are being sold pursuant to a Registration 
Statement and that does not directly or indirectly affect the rights of 
other Holders may be given by the Majority Holders, determined on the 
basis of Securities being sold rather than registered under such 
Registration Statement.

     Securities and/or New Securities.  The Company hereby agrees to extend

     of this Agreement as if an original party hereto.

        (e) COUNTERPARTS.  This agreement may be executed in any number of

     which taken together shall constitute one and the same agreement.

        (f) HEADINGS.  The headings in this agreement are for convenience of 
     reference only and shall not limit or otherwise affect the meaning 
     hereof.
     
        (g) GOVERNING LAW.  This agreement shall be governed by and construed 
     in accordance with the internal laws of the State of New York without

        (h) SEVERABILITY.  In the event that any one or more of the 
     provisions contained herein, or the application thereof in any 
     circumstances, is held invalid, illegal or unenforceable in any respect 
     for any reason, the validity, legality and enforceability of any such 
     provision in every other respect and of the remaining provisions hereof 
     shall not be in any way impaired or affected thereby, it being intended 
     that all of the rights and privileges of the parties shall be 
     enforceable to the fullest extent permitted by law.

        (i) SECURITIES HELD BY THE COMPANY, ETC.  Whenever the consent or 
     approval of Holders of a specified percentage of principal amount of 
     Securities or New Securities is required hereunder, Securities or New 
     Securities, as applicable, held by the Company or its Affiliates (other 
     than subsequent Holders of Securities or New Securities if such 
     subsequent Holders are deemed to be Affiliates solely by reason of their 
     holdings of such Securities or New Securities) shall not be counted in 
     determining whether such consent or approval was given by the Holders of 
     such required percentage.

     If the foregoing is in accordance with your understanding of our 
agreement, please sign and return to the Company a counterpart hereof, 
whereupon this instrument, along with all counterparts, will become a binding 
agreement among the several Initial Purchasers and the Company in accordance

Each broker-dealer that receives New Securities for its own account pursuant 
to the Exchange Offer must acknowledge that it will deliver a prospectus in 
connection with any resale of such New Securities.  The Letter of Transmittal 
states that by so acknowledging and by delivering a prospectus, a 
broker-dealer will not be deemed to admit that it is an "underwriter" within 
the meaning of the Securities Act.  This Prospectus, as it may be amended or 
supplemented from time to time, may be used by a broker-dealer in connection 
with resales of New Securities received in exchange for Securities where such 
New Securities were acquired by such broker-dealer as a result of 
market-making activities or other trading activities.  The Company has agreed 
that, starting on the Expiration Date (as defined herein) and ending on the 
close of business on the 180th day following the Expiration Date, it will 
make this Prospectus available to any broker-dealer for use in connection 
with any such resale.  See "Plan of Distribution."

Each broker-dealer that receives New Securities for its own account in 
exchange for Securities, where such Securities were acquired by such 
broker-dealer as a result of market-making activities or other trading 
activities, must acknowledge that it will deliver a prospectus in connection 
with any resale of such New Securities.  See "Plan of Distribution."

                            PLAN OF DISTRIBUTION


     Each broker-dealer that receives New Securities for its own account 
pursuant to the Exchange Offer must acknowledge that it will deliver a 
prospectus in connection with any resale of such New Securities.  The 
Prospectus, as it may be amended or supplemented from time to time, may be 
used by a broker-dealer in connection with resales of New Securities received 
in exchange for Securities where such Securities were acquired as a result of 
market-making activities or other trading activities.  The Company has agreed 
that, starting on the Expiration Date and ending on the close of business on 
the 180th day following the Expiration Date, it will make this Prospectus, as 
amended or supplemented, available to any broker-dealer for use in connection 
with any such resale.  In addition, until __________, 199__, all dealers 
effecting transactions in the Exchange Securities may be required to deliver 
a prospectus. */ 

     The Company will not receive any proceeds from any sale of New 
Securities by broker-dealers.  New Securities received by broker-dealers for 
their own account pursuant to the Exchange Offer may be sold from time to 
time in one or more transactions in the over-the-counter market, in 
negotiated transactions, through the writing of options on the New Securities 
or a combination of such methods of resale, at market prices prevailing at 
the time of resale, at prices related to such prevailing market prices or 
negotiated prices.  Any such resale may be made directly to purchasers or to 
or through brokers or dealers who may receive compensation in the form of 
commissions or concessions from any such broker-dealer and/or the purchasers 
of any such New Securities.  Any broker-dealer that resells New Securities 
that were received by it for its own account pursuant to the Exchange Offer 
and any broker or dealer that participates in a distribution of such New 
Securities may be deemed to be an "underwriter" within the meaning of the 
Securities Act and any profit of any such resale of New Securities and any 
commissions or concessions received by any such persons may be deemed to be 
underwriting compensation under the Securities Act.  The Letter of 
Transmittal states that by acknowledging that it will deliver and by 
delivering a prospectus, a broker-dealer will not be deemed to admit that it 
is an "underwriter" within the meaning of the Securities Act.

     For a period of 180 days after the Expiration Date, the Company will 
promptly send additional copies of this Prospectus and any amendment or 
supplement to this Prospectus to any broker-dealer that requests such 
documents in the Letter of Transmittal.  The Company has agreed to pay all 
expenses incident to the Exchange Offer (including the expenses of one 
counsel for the holders of the Securities) other than commissions or 
concessions of any brokers or dealers and will indemnify the holders of the 
Securities (including any broker-dealers) against certain liabilities, 
including liabilities under the Securities Act.

Oklahoma City, OK  73134


Ladies and Gentlemen:

     We have acted as counsel to Louis Dreyfus Natural Gas Corp., an Oklahoma 
corporation (the "Company"), in connection with the preparation and filing 
with the Securities and Exchange Commission of the Company's Registration 
Statement on Form S-4 (the "Registration Statement") under the Securities Act 
of 1933, as amended, relating to $200,000,000 principal amount of the 
Company's 6 7/8% Senior Notes due 2007 (the "Exchange Notes").

     In so acting, we have examined originals or copies, certified or 
otherwise identified to our satisfaction, of the Registration Statement, the 
Indenture dated as of December 11, 1997, between the Company and LaSalle 
National Bank, as trustee (the "Trustee"), the form of the Exchange Notes 
included within Exhibit 4.1 to the Registration Statement and such corporate 
records, agreements, documents and other instruments, and such certificates 
or comparable documents of public officials and of officers and 
representatives of the Company, and have made such inquiries of such officers 
and representatives, as we have deemed relevant and necessary as a basis for 
the opinion hereinafter set forth.

     In such examination, we have assumed the genuineness of all signatures, 
the legal capacity of natural persons, the authenticity of all documents 
submitted to us as originals, the conformity to original documents of all 
documents submitted to us as certified, conformed or photostatic copies and 
the authenticity of the originals of such latter documents.  As to all 
questions of fact material to this opinion that have not been independently 
established, we have relied upon certificates or comparable documents of 
officers and representatives of the Company.

     Based on the foregoing, and subject to the qualifications stated herein, 
we are of the opinion that the Exchange Notes are duly authorized, and, when 
duly executed on behalf of the Company, authenticated by the Trustee and 
delivered in accordance with the terms of the Indenture and as contemplated 
by the Registration Statement, will constitute legal, valid and binding 
obligations of the Company, enforceable against it in accordance with their 
terms, subject to applicable bankruptcy, insolvency, fraudulent conveyance, 
reorganization, moratorium and similar laws affecting creditors' rights and 
remedies generally, and subject, as to enforceability, to general principles 
of equity, including principles of commercial reasonableness, good faith and 
fair dealing (regardless of whether enforcement is sought in a proceeding at 
law or in equity).

connection with the transactions described herein.  This opinion may not be 
used or relied upon by any other person, nor may this letter or any copies 
thereof be furnished to a third party, filed with a governmental agency,

                           LOUIS DREYFUS NATURAL GAS CORP.
      RATIO OF EARNINGS TO COMBINED FIXED CHARGES AND PREFERRED STOCK DIVIDENDS

    For purposes of these computations, earnings consist of income before
income taxes and fixed charges less capitalized interest.  Fixed charges consist
of interest expense, including amortization of debt discount and financing
costs, capitalized interest, the portion of rental expense which LDNG believes
is representative of the interest component of rental expense.

substantially the same action, suit, or proceeding, constituting a majority 
of the whole number of the directors. The foregoing right of indemnification

     The undersigned acknowledges that he, she or it has received and 
reviewed the Prospectus, dated _____________, 1998  (the "Prospectus"), of 
Louis Dreyfus Natural Gas Corp., an Oklahoma corporation (the "Company"), and 
this Letter of Transmittal (the"Letter of Transmittal"), which together 
constitute the Company's offer (the "Exchange Offer") to exchange its 6-7/8% 
Senior Notes due 2007, which have been registered under the Securities Act 
(the "Exchange Notes") for an equal principal amount of its 6-7/8% Senior Notes
due 2007 which have not been so registered (the "Existing Notes"). The 
Exchange Notes and the Existing Notes are collectively referred to as the 
"Notes." Capitalized terms used but not defined herein have the meanings 
ascribed to them in the Prospectus.

     The undersigned has completed the appropriate boxes above and below and 
signed this Letter of Transmittal to indicate the action the undersigned 
desires to take with respect to the Exchange Offer.

     This Letter of Transmittal is to be used by holders of Existing Notes to 
accept the Exchange Offer if: (i) tender of Existing Notes is to be made 
according to the Automated Tender Offer Program ("ATOP") of Depository Trust  
Company ("DTC"), for which the transaction is eligible, pursuant to the 
procedures set forth in the Prospectus under the caption "The Exchange 
Offer--Procedures for Tendering--Existing Notes Held Through DTC"; (ii) 
certificates representing Existing Notes are to be physically delivered to 
the Exchange Agent herewith by such holders, pursuant to the procedures set 
forth in the Prospectus under the caption "The Exchange Offer--Procedures for 
Tendering--Existing Notes Held by Holders"; or (iii) tender of Existing Notes 
is to  be made according to the guaranteed delivery procedures set forth in 
the Prospectus under the caption "The Exchange Offer--Guaranteed Delivery 
Procedures." 

     NOTWITHSTANDING THE FOREGOING, VALID ACCEPTANCE OF THE TERMS OF THE 
EXCHANGE OFFER MAY BE EFFECTED BY A PARTICIPANT IN DTC (A "DTC PARTICIPANT") 
TENDERING EXISTING NOTES THROUGH ATOP WHERE THE EXCHANGE AGENT RECEIVES AN 
AGENT'S MESSAGE (AS DEFINED IN THE PROSPECTUS) PRIOR TO THE EXPIRATION DATE. 
ACCORDINGLY, SUCH DTC PARTICIPANT MUST ELECTRONICALLY TRANSMIT ITS ACCEPTANCE 
TO DTC THROUGH ATOP, AND THEN DTC WILL EDIT AND VERIFY THE ACCEPTANCE, 
EXECUTE A BOOK-ENTRY DELIVERY TO THE EXCHANGE AGENT'S ACCOUNT AT DTC AND SEND 
AN AGENT'S MESSAGE TO THE EXCHANGE AGENT FOR ITS ACCEPTANCE. BY TENDERING 
THROUGH ATOP, DTC PARTICIPANTS WILL EXPRESSLY ACKNOWLEDGE RECEIPT OF THIS 
LETTER OF TRANSMITTAL AND AGREE TO BE BOUND BY ITS TERMS AND THE COMPANY WILL 
BE ABLE TO ENFORCE SUCH AGREEMENT AGAINST SUCH DTC PARTICIPANTS. 

     DELIVERY OF DOCUMENTS TO DTC DOES NOT CONSTITUTE DELIVERY TO THE 
EXCHANGE AGENT.    

     DTC Participants who wish to cause their Existing Notes to be tendered, 
but who cannot transmit their acceptances through ATOP prior to the 
Expiration Date, may effect a tender in accordance with the guaranteed 
delivery procedures set forth in the Prospectus under the caption "The 
Exchange Offer--Guaranteed Delivery Procedures--Existing Notes Held Through 
DTC." Holders who wish to tender their Existing Notes but (i) whose Existing 
Notes are not immediately available and will not be available for tendering 
prior to the Expiration Date, or (ii) who cannot deliver their Existing 
Notes, the Letter of Transmittal, or any other required documents to the 
Exchange Agent prior to the Expiration Date, may effect a tender in 
accordance with the guaranteed delivery procedures set forth in the 
Prospectus under the caption "The Exchange Offer--Guaranteed Delivery 
Procedures--Existing Notes Held by Holders."    

     The undersigned must complete the appropriate boxes above and below and 
sign this Letter of Transmittal to indicate the action the undersigned 
desires to take with respect to the Exchange Offer.

     AGENT IN EXCHANGE FOR CERTIFICATED EXCHANGE NOTES.

     Unless the undersigned (i) has completed Item (4) in the box

such registered global certificates will be shown on, and transfers thereof

            PLEASE READ THE ACCOMPANYING INSTRUCTIONS CAREFULLY 

Ladies and Gentlemen:

     Upon the terms and subject to conditions of the Exchange Offer, the 
undersigned hereby tenders to the Company the Existing Notes indicated above. 
Subject to, and effective upon, the acceptance for exchange of the Existing 
Notes tendered hereby, the undersigned hereby sells, assigns and transfers 
to, or upon the order of, the Exchange Agent, as agent of the Company, all 
right, title and interest in and to such Existing Notes as are being tendered 
hereby, and irrevocably constitutes and appoints the Exchange Agent as the 
agent and attorney-in-fact of the undersigned to cause the Existing Notes 
tendered hereby to be transferred and exchanged.

     The undersigned hereby represents and warrants that the undersigned has 
full power and authority to tender, exchange, sell, assign and transfer the 
Existing Notes tendered hereby and to acquire the Exchange Notes issuable 
upon the Exchange of such tendered Existing Notes, and that the Exchange 
Agent, as agent of the Company, will acquire good and unencumbered title 
thereto, free and clear of all liens, restrictions, charges and encumbrances 
and not subject to any adverse claim when the same are accepted by the 
Exchange Agent, as agent of the Company. The undersigned will, upon request, 
execute and deliver any additional documents deemed by the Company or the 
Exchange Agent to be necessary or desirable to complete the exchange, sale, 
assignment and transfer of the Existing Notes tendered hereby.

     The undersigned also acknowledges that this Exchange Offer is being made 
in reliance on the interpretation of the staff of the Securities and Exchange 
Commission (the "SEC"), as set forth in "Exxon Capital Holdings Corporation" 
(available May 13, 1988) and similar no-action letters issued to third 
parties.  Based on such interpretation of the staff of the SEC set forth in 
such no-action letters, the Company believes that the Exchange Notes issued 
in exchange for the Existing Notes pursuant to the Exchange Offer may be 
offered for resale, resold and otherwise transferred by a holder thereof 
(other than (i) a broker-dealer who purchases such Exchange Notes from the 
Company to resell pursuant to Rule144A or any other available exemption under 
the Securities Act, or (ii) a person that is an "affiliate" of the Company 
within the meaning of Rule 405 under the Securities Act of 1933, as amended 
(the "Securities Act")) without compliance with the registration and 
prospectus delivery requirements of the Securities Act, provided that (i) 
such Exchange Notes are acquired in the ordinary course of such holder's 
business, (ii) at the time of the commencement of the Exchange Offer such 
holder has no arrangement with any person to participate in a distribution of 
the Exchange Notes, and (iii) such holder is not engaged in, and does not 
intend to engage in, a distribution of the Exchange Notes. However, the SEC 
has not considered the Exchange Offer in the context of a no-action letter 
and there can be no assurance that the Staff of the SEC would make a similar 
determination with respect to the Exchange Offer as in other circumstances. 
By tendering Existing Notes in exchange for Exchange Notes, each holder will 
represent to the Company that: (i) it is not such an affiliate of the 
Company,(ii) any Exchange Notes to be received by it will be acquired in the 
ordinary course of business, and (iii) at the time of the commencement of the 
Exchange Offer it had no arrangement with any person to participate in a 
distribution of the Exchange Notes.

     If the undersigned is not a broker-dealer or is a broker-dealer but will 
not receive Exchange Notes for its own account in exchange for Existing 
Notes, the undersigned represents that it is not engaged in, and does not 
intend to engage in, a distribution of Exchange Notes. If the undersigned is 
a broker-dealer that will receive Exchange Notes for its own account in 
exchange for Existing Notes, where such Existing Notes were acquired as a 
result of market-making activities or other trading activities, it 
acknowledges that it will deliver a prospectus meeting the requirements of 
the Securities Act in connection with any resale of such Exchange Notes; 
however, by so acknowledging and by delivering a prospectus, the undersigned 
will not be deemed to admit that it is an"underwriter" within the meaning of 
the Securities Act. Nevertheless, a broker-dealer may be deemed to be an 
"underwriter" under the Securities Act notwithstanding such disclaimer. The 
SEC has taken the position that such broker-dealers may fulfill their 
prospectus delivery requirements with respect to the Exchange Notes (other 
than a resale of Exchange Notes received in exchange for an unsold allotment 
from the original sale of the Existing Notes) with the Prospectus. The 
Prospectus, as it may be amended or supplemented from time to time, may be 
used by such broker-dealers for a period of time, starting on the Expiration 
Date and ending on the close of business 180 days after the Expiration Date. 
The Company has agreed that for such period of time, it will make the 
Prospectus (as it maybe amended or supplemented) available to each 
broker-dealer which exchanges Existing 

                                      5
<PAGE>

Notes acquired for its own account as a result of  market-making activities 
or other trading activities for Exchange Notes pursuant to the Exchange Offer 
(each a "Participating Broker-Dealer") for use in connection with any resale 
of such Exchange Notes. By acceptance of the Exchange Offer, each 
broker-dealer that receives Exchange Notes pursuant to the Exchange Offer 
hereby acknowledges and agrees to notify the Company prior to using the 
Prospectus in connection with the sale or transfer of Exchange Notes and 
that, upon receipt of notice from the Company of the happening of any event 
which makes any statement in the Prospectus untrue in any material respect or 
which requires the making of any changes in the Prospectus in order to make 
the statements therein not misleading, such broker-dealer will suspend use of 
the Prospectus until (i) the Company has amended or supplemented the 
Prospectus to correct such misstatement or omission and (ii) either the 
Company has furnished copies of the amended or supplemented Prospectus to 
such broker-dealer or, if the Company has not otherwise agreed to furnish 
such copies and declines to do so after such broker-dealer so requests, such 
broker-dealer has obtained a copy of such amended or supplemented Prospectus 
as filed with the SEC. The Company agrees to deliver such notice and such 
amended or supplemented Prospectus promptly to any Participating 
Broker-Dealer that has so notified the Company. Except as described above, 
the Prospectus may not be used for or in connection with an offer to resell, 
a resale or any other retransfer of Exchange Notes.

     The undersigned represents that (i) the Exchange Notes acquired pursuant 
to the Exchange Offer are being obtained in the ordinary course of such 
holder's business, (ii) such holder is not participating and has no 
arrangements with any person to participate in the distribution of such 
Exchange Notes or, if such holder intends to participate in the Exchange 
Offer for the purpose of distributing the Exchange Notes, such holder will 
comply with the registration and prospectus delivery requirements of the 
Securities Act to the extent applicable, and (iii) (x) such holder is not (a) 
a broker-dealer that will receive Exchange Notes for its own account in 
exchange for Existing Notes that were acquired as a result of market-making 
activities or other trading activities, or (b) an "affiliate," as defined in 
Rule 405 under the Securities Act, of the Company or (y) if such holder is 
such a broker-dealer or an affiliate, such holder will comply with the 
registration and prospectus delivery requirements of the Securities Act to 
the extent applicable.

     All authority conferred or agreed to be conferred in this Letter of 
Transmittal and every obligation of the undersigned hereunder shall be 
binding upon the successors, assigns, heirs, executors, administrators, 
trustees in bankruptcy and legal representatives of the undersigned and shall 
not be affected by, and shall survive, the death or incapacity of the 
undersigned. This tender may be withdrawn only in accordance with the 
procedures set forth in the instructions contained in this Letter of 
Transmittal.

     The undersigned understands that tenders of the Existing Notes pursuant 
to any one of the procedures described under "The Exchange Offer--Procedures 
for Tendering" in the Prospectus and in the instructions hereto will 
constitute a binding agreement between the undersigned and the Company in 
accordance with the terms and subject to the conditions of the Exchange Offer.

     The undersigned understands that if its Existing Notes are accepted for 
exchange, interest on the Exchange Notes will accumulate from the last 
interest payment date on which interest was paid on the Existing Notes 
surrendered in exchange therefor, or if no interest has been paid, from the 
original date of issuance of the Existing Notes.    

     The undersigned recognizes that unless the holder of Existing Notes (i) 
completes Item (4) of the box entitled "Description of Existing Notes 
Tendered"above and (ii) checks the box entitled "Check Here If Tendered 
Shares of Existing Notes Are Being Delivered to the Exchange Agent in 
Exchange for Certificated Exchange Notes" above, such holder, when tendering 
such Existing Notes, will be deemed to have tendered such Existing Notes in 
exchange for a beneficial interest in one or more fully registered global 
certificates, which will be deposited with, or on behalf of, DTC and 
registered in the name of Cede & Co., its nominee. Beneficial interests in 
such registered global certificates will be shown on, and transfers thereof 
will be effected only through, records maintained by DTC and its 
participants. See "Description of Exchange Notes--Book-Entry; Delivery and 
Form" in the Prospectus.     The undersigned recognizes that, under certain 
circumstances set forth in the Prospectus under "The Exchange 
Offer--Conditions," the Company may not be required to accept for exchange 
any of the Existing Notes tendered. Existing Notes not accepted for exchange 
or withdrawn will be returned to the undersigned at the address set forth

                                INSTRUCTIONS
       FORMING PART OF THE TERMS AND CONDITIONS OF THE EXCHANGE OFFER

     1.  DELIVERY OF THIS LETTER OF TRANSMITTAL AND EXISTING NOTES; 
GUARANTEED DELIVERY PROCEDURE.  This Letter of Transmittal is to be completed 
by holders of Existing Notes to accept the Exchange Offer if: (i) tendering 
holders are not ATOP members; (ii) tendering holders are ATOP members but 
choose not to use ATOP; (iii) certificates representing Existing Notes are to 
be physically delivered to the Exchange Agent herewith by such holders, 
pursuant to the procedures set forth in the Prospectus under the caption "The 
Exchange Offer--Procedures for Tendering--Existing Notes Held by Holders"; or 
(iv) tender of Existing Notes is to be made according to the guaranteed 
delivery procedures set forth in the Prospectus under the caption "The 
Exchange Offer--Guaranteed delivery Procedures." Existing Notes tendered must 
be in denominations of principal amount at maturity of $1,000 or any integral 
multiples thereof.  NOTWITHSTANDING THE FOREGOING, VALID ACCEPTANCE OF THE 
TERMS OF THE EXCHANGE OFFER MAY BE EFFECTED BY A DTC PARTICIPANT TENDERING 
EXISTING NOTES THROUGH ATOP WHERE THE EXCHANGE AGENT RECEIVES AN AGENT'S 
MESSAGE PRIOR TO THE EXPIRATION DATE. ACCORDINGLY, SUCH DTC PARTICIPANT MUST 
ELECTRONICALLY TRANSMIT ITS ACCEPTANCE TO DTC THROUGH ATOP, AND THEN DTC WILL 
EDIT AND VERIFY THE ACCEPTANCE, EXECUTE A BOOK-ENTRY DELIVERY TO THE EXCHANGE 
AGENT'S ACCOUNT AT DTC AND SEND AN AGENT'S MESSAGE TO THE EXCHANGE AGENT FOR 
ITS ACCEPTANCE. BY TENDERING THROUGH ATOP, DTC PARTICIPANTS WILL EXPRESSLY 
ACKNOWLEDGE RECEIPT OF THIS LETTER OF TRANSMITTAL AND AGREE TO BE BOUND BY 
ITS TERMS AND THE COMPANY WILL BE ABLE TO ENFORCE SUCH AGREEMENT AGAINST SUCH 
DTC PARTICIPANTS. 

     In order to validly tender Existing Notes pursuant to the Exchange 
Offer, either (i) (A) this Letter of Transmittal, or a facsimile hereof, 
together with certificates representing Existing Notes or (B) a Book-Entry 
Confirmation (as defined in the Prospectus), including by means of an Agent's 
Message, of the transfer into the Exchange Agent's account at DTC of all 
Existing Notes delivered electronically must be received by the Exchange 
Agent at its address set forth herein prior to 5:00 p.m., New York City time, 
on the Expiration Date, together with all other required documents, or (ii) 
the tendering holder must comply with the guaranteed delivery procedures set 
forth below. DELIVERY OF DOCUMENTS TO DTC DOES NOT CONSTITUTE DELIVERY TO THE 
EXCHANGE AGENT.

     If a holder or DTC Participant desires to tender Existing Notes pursuant 
to the Exchange Offer and time will not permit this Letter of Transmittal, 
certificates representing such Existing Notes and all other required 
documents to reach the Exchange Agent, or the procedures for book-entry 
transfer, including those with respect to tenders through ATOP, cannot be 
completed, prior to the Expiration Date, such holder or DTC Participant, as 
the case may be, must tender such Existing Notes pursuant to the guaranteed 
delivery procedures set forth in the Prospectus under the caption "The 
Exchange Offer-- Procedures for Tendering--Guaranteed Delivery Procedures." 
Pursuant to such procedures (i) such tender must be made by or through an 
Eligible Institution; (ii) a properly completed and duly executed Notice of 
Guaranteed Delivery, substantially in the form provided by the Company, must 
be received by the Exchange Agent either by hand delivery, mail, facsimile 
transmission or overnight courier, prior to the Expiration Date; and (iii) 
within three NYSE trading days after the date of the execution of the Notice 
of Guaranteed Delivery, (A) holders must deliver to the Exchange Agent a 
properly completed and duly executed Letter of Transmittal as well as the 
certificate(s) representing all tendered Existing Notes in proper form for 
transfer, and all other documents required by the Letter of Transmittal or 
(B) DTC Participants must effect a Book-Entry Confirmation, including through 
ATOP by means of an Agent's Message, of the transfer of such Existing Notes 
into the Exchange Agent's account at DTC as set forth in the Prospectus.     

     THE METHOD OF DELIVERY OF THIS LETTER OF TRANSMITTAL, THE EXISTING NOTES 
AND ALL OTHER REQUIRED DOCUMENTS, INCLUDING DELIVERY THROUGH DTC AND ANY 
ACCEPTANCE OR AGENT'S MESSAGE TRANSMITTED THROUGH ATOP, IS AT THE OPTION AND 
RISK OF THE TENDERING HOLDER. If delivery is by mail, registered mail with 
return receipt requested, properly insured, is recommended. In all cases, 
sufficient time should be allowed for such documents to reach the Exchange 
Agent prior to the Expiration Date. Except as otherwise provided in this 
Instruction 1, delivery will be deemed made only when actually received by 
the Exchange Agent.     

                                     11
<PAGE>

     No alternative, conditional or contingent tenders will be accepted. All 
tendering holders, by execution of this Letter of Transmittal (or a facsimile 
hereof), waive any right to receive any notice of the acceptance of their 
Existing Notes for exchange.    

     See "The Exchange Offer" in the Prospectus.    

     2.  WITHDRAWALS. Tenders of Existing Notes may be withdrawn at any time 
prior to 5:00 p.m., New York City time, on the Expiration Date. For a 
withdrawal of a tender of Existing Notes to be effective, a letter, telex, 
telegram or facsimile transmission notice of withdrawal must be received by 
the Exchange Agent at its address set forth above prior to 5:00 p.m., New 
York City time, on the Expiration Date. Any such notice of withdrawal by a 
DTC Participant must contain the name and number of the DTC Participant, the 
principal amount due at the stated maturity of Existing Notes to which such 
withdrawal relates and the signature of the DTC Participant. Any such notice 
of withdrawal by a holder of Existing Notes must (i) specify the name of the 
person who tendered the Existing Notes to be withdrawn, (ii) contain a 
description of the Existing Notes to be withdrawn (including the certificate 
number or numbers and principal amount due at the stated maturity of such 
Existing Notes) and (iii) be signed by the holder of such Existing Notes in 
the same manner as the original signature on this Letter of Transmittal 
(including any required signature guaranties), or be accompanied by (x) 
documents of transfer in a form acceptable to the Company, in its sole 
discretion and (y) a properly completed irrevocable proxy that authorized 
such person to effect such revocation on behalf of such holder. Any Existing 
Notes so withdrawn will be deemed not to have been validly tendered for 
exchange for purposes of the Exchange Offer. Any Existing Notes which have 
been tendered for exchange but which are not exchanged for any reason will be 
returned to the holder thereof without cost to such holder as soon as 
practicable after withdrawal, rejection of tender, or termination of the 
Exchange Offer. Properly withdrawn Existing Notes may be retendered by 
following the procedures described above at any time on or prior to 5:00 
p.m., New York City time, on the Expiration Date.

     3.  SIGNATURES ON THIS LETTER OF TRANSMITTAL; BOND POWERS AND 
ENDORSEMENTS; GUARANTEE OF SIGNATURES. If this Letter of Transmittal is 
signed by the registered holder of the Existing Notes tendered hereby, the 
signature must correspond exactly with the name as written on the face of the 
certificates without any change whatsoever.

     If any tendered Existing Notes are owned of record by two or more joint 
owners, all such owners must sign this Letter of Transmittal.

     If any tendered Existing Notes are registered in different names on 
several certificates, it will be necessary to complete, sign and submit as 
many separate copies of this Letter of Transmittal as there are different 
registrations of certificates.

     If this Letter of Transmittal or any Existing Notes or powers of 
attorney are signed by trustees, executors, administrators, guardians, 
attorneys-in-fact, officers of corporations or others acting in a fiduciary 
or representative capacity, such persons should indicate such capacity when 
signing, and unless waived by the Company, proper evidence satisfactory to 
the Company of their authority so to act must be submitted.  The signatures 
on this Letter of Transmittal or a notice of withdrawal, as the case may be, 
must be guaranteed unless the Existing Notes surrendered for exchange 
pursuant thereto are tendered (i) by a registered holder of the Existing 
Notes who has not completed the box entitled "Special Issuance Instructions" 
or "Special Delivery Instructions" in this Letter of Transmittal or (ii) for 
the account of an Eligible Institution. In the event that the signatures in 
this Letter of Transmittal or a notice of withdrawal, as the case may be, are 
required to be guaranteed, such guarantees must be by a firm which is a 
member of a registered national securities exchange or a member of the 
national Association of Securities Dealers,  Inc., or by a commercial bank or 
trust company having an office or correspondent in the United States, or an 
"eligible guarantor institution" within the meaning of Rule 17Ad-15 of the 
Securities Exchange Act of 1934, as amended (each an "Eligible Institution").

     If Existing Notes are registered in the name of a person other than the 
signer of this Letter of Transmittal, the Existing Notes surrendered for 
exchange must be endorsed by, or be accompanied by a written instrument or 
instruments of transfer or exchange, in satisfactory form as determined by 
the Company in its sole discretion, duly executed by the registered holder 
with the signature thereon guaranteed by an Eligible Institution.

                                     12
<PAGE>

     4.  SPECIAL ISSUANCE AND DELIVERY INSTRUCTIONS. Tendering holders of 
Existing Notes should indicate in the applicable box the name and address to 
which Exchange Notes issued pursuant to the Exchange Offer are to be issued 
or sent, if different from the name or address of the person signing this 
Letter of Transmittal. In the case of issuance in a different name, the 
employer identification or social security number of the person named must 
also be indicated. If no such instructions are given, any Exchange Notes will 
be issued in the name of, and delivered to, the name or address of the person 
signing this Letter of Transmittal and any Existing Notes not accepted for 
exchange will be returned to the name or address of the person signing this 
Letter of Transmittal.

     5.  BACKUP FEDERAL INCOME TAX WITHHOLDING AND SUBSTITUTE FORM W-9. Under 
the federal income tax laws, payments that may be made by the Company on 
account of Exchange Notes issued pursuant to the Exchange Offer may be 
subject to backup withholding at the rate of 31%. In order to avoid such 
backup withholding, each tendering holder should complete and sign the 
Substitute Form W-9 included in this Letter of Transmittal and either (a) 
provide the correct Taxpayer Identification number ("TIN") and certify, under 
penalties of perjury, that the TIN provided is correct and that (i) the 
holder has not been notified by the Internal Revenue Service (the "IRS") that 
the holder is subject to backup withholding as a result of failure to report 
all interest or dividends or (ii) the IRS has notified the holder that the 
holder is no longer subject to backup withholding; or (b) provide an adequate 
basis for exemption. If the tendering holder has not been issued a TIN and 
has applied for one, or intends to apply for one in the near future, such 
holder should write "Applied For" in the space provided for the TIN in Part I 
of the Substitute Form W-9, sign and date the Substitute Form W-9 and sign 
the Certificate of Payee Awaiting Taxpayer Identification Number. If "Applied 
For" is written in Part I, the Company (or the Transfer Agent with respect to 
the Exchange Notes or a broker or custodian)may still withhold 31% of the 
amount of any payments made on account of the Exchange Notes until the holder 
furnishes the Company or the Transfer Agent with respect to the Exchange 
Notes, broker or custodian with its TIN. In general, if a holder is an 
individual, the taxpayer identification number is the Social Security number 
of such individual. If the Exchange Agent or the Company is not provided with 
the correct TIN, the holder may be subject to a $50 penalty imposed by the 
IRS. Certain holders (including, among others, all corporations and certain 
foreign individuals) are not subject to these backup withholding and 
reporting requirements. In order for a foreign individual to qualify as an 
exempt recipient, such holder must submit a statement (generally, IRS Form 
W-8), signed under penalties of perjury, attesting to that individual's 
exempt status.  Such statements can be obtained from the Exchange Agent. For 
further information concerning backup withholding and instructions for 
completing the Substitute Form W-9 (including how to obtain a taxpayer 
identification number if you do not have one and how to complete the 
Substitute Form W-9 if Existing Notes are registered in more than one name), 
consult the enclosed Guidelines for Certification of Taxpayer Identification 
Number on Substitute Form W-9.  Failure to complete the Substitute Form 
W-9 will not, by itself, cause the Existing Notes to be deemed invalidly 
tendered, but may require the Company or the Transfer Agent with respect to 
the Exchange Notes, broker or custodian to withhold 31% of the amount of any 
payments made on account of the Exchange Notes. Backup withholding is not an 
additional federal income tax. Rather, the federal income tax liability of a 
person subject to backup withholding will be reduced by the amount of tax 
withheld. If withholding results in an overpayment of taxes, a refund may be 
obtained from the IRS.

     6.  TRANSFER TAXES. The Company will pay all transfer taxes, if any, 
applicable to the transfer of Existing Notes to it or its order pursuant to 
the Exchange Offer. If, however, Exchange Notes and/or substitute Existing 
Notes not exchanged are to be delivered to, or are to be registered or issued 
in the name of, any person other than the registered holder of the Existing 
Notes tendered hereby, or if tendered Existing Notes are registered in the 
name of any person other than the person signing this Letter of Transmittal, 
or if a transfer tax is imposed for any reason other than the transfer of 
Existing Notes to the Company or its order pursuant to the Exchange Offer, 
the amount of any such transfer taxes (whether imposed on the registered 
holder or any other person) will be payable by the tendering holder. If 
satisfactory evidence of payment of such taxes or exemption therefrom is not 
submitted herewith, the amount of such transfer taxes will be billed directly 
to such tendering holder.

     Except as provided in this Instruction 6, it will not be necessary for 
transfer tax stamps to be affixed to the Existing Notes specified in this 
Letter of Transmittal.

                                     13
<PAGE>

     7.  WAIVER OF CONDITIONS. The Company reserves the absolute right to 
waive satisfaction of any or all conditions enumerated in the Prospectus.

     8.  NO CONDITIONAL TENDERS. No alternative, conditional, irregular or 
contingent tenders will be accepted. All tendering holders of Existing Notes, 
by execution of this Letter of Transmittal, shall waive any right to receive 
notice of the acceptance of their Existing Notes for exchange.  Neither the 
Company nor any other person is obligated to give notice of defects or 
irregularities in any tender, nor shall any of them incur any liability for 
failure to give any such notice.

     9.  INADEQUATE SPACE. If the space provided herein is inadequate, the 
aggregate principal amount of Existing Notes being tendered and the 
certificate number or numbers (if available) should be listed on a separate 
schedule attached hereto and separately signed by all parties required to 
sign this Letter of Transmittal.

     10.  MUTILATED, LOST, STOLEN OR DESTROYED EXISTING NOTES. Any holder 
whose Existing Notes have been mutilated, lost, stolen or destroyed should 
contact the Exchange Agent at the address indicated above for further 
instructions.

     11.  REQUESTS FOR ASSISTANCE OR ADDITIONAL COPIES. Questions relating to 
the procedure for tendering, as well as requests for additional copies of the 
Prospectus and this Letter of Transmittal, may be directed to the Exchange 
Agent at the address and telephone number indicated above.
