                         AMERICAN EXPLORATION COMPANY
             CONDENSED NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


(1)  BASIS OF PRESENTATION

     The condensed consolidated financial statements included herein have been
prepared by American Exploration Company ("American" or the "Company"),
without audit, pursuant to the rules and regulations of the Securities and
Exchange Commission (the "Commission").  The financial statements reflect
adjustments of a normal recurring nature which are, in the opinion of
management, necessary to present fairly such information.  Although the
Company believes that the disclosures are adequate to make the information
presented not misleading, certain information and footnote disclosures,
including significant accounting policies, normally included in financial
statements prepared in accordance with generally accepted accounting
principles have been condensed or omitted pursuant to such rules and
regulations.  It is suggested that these condensed consolidated financial
statements be read in conjunction with the financial statements and the notes
thereto included in the Company's Annual Report on Form 10-K for the year
ended December 31, 1996.  Certain amounts in the prior year financial
statements have been reclassified to conform with current classifications.

(2)  MERGER AGREEMENT

     On June 24, 1997, the Company entered into an Agreement and Plan of
Reorganization (the "Merger Agreement") with Louis Dreyfus Natural Gas Corp.
("LDNG") that provides for the acquisition of the Company by LDNG (the
"Merger").  The Merger was subsequently approved by the stockholders of LDNG
and American on October 14, 1997 (the "Merger Date").  Pursuant to the terms
of the Merger Agreement, holders of the Company's common stock received 0.72
shares of LDNG common stock and $3.00 cash for each share of the Company's
common stock.  An aggregate of approximately 11.3 million shares of LDNG
common stock was issued and approximately $47.2 million was paid in the Merger
for total consideration of approximately $308 million (based on the closing
price of LDNG common stock on the Merger Date).  Holders of American's
convertible preferred stock received LDNG preferred shares.  As of the Merger
Date, American ceased to exist as an independent company.

(3)  EAST CAMERON BLOCK 328

     On April 1, 1997, a blowout and fire occurred during the drilling of a
horizontal development well at East Cameron Block 328 located in federal
waters offshore Louisiana.  No personnel were injured in the accident.  The
upper structure of the platform, which was owned by the Company, was severely
damaged.  In addition, the drilling rig operated by a third party contractor
and various other subcontractors' equipment were damaged or destroyed. 
During the second quarter of 1997, the Company successfully capped the well
and secured the four remaining wells on the platform.  The production deck was
removed and dismantled, and certain production equipment has been salvaged. 
The Company is rebuilding the production deck and expects to restore




   8
                         AMERICAN EXPLORATION COMPANY
        CONDENSED NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (continued)


production from the platform in the second quarter of 1998.

     The Company carries various types of insurance relating to the blowout
and estimates that total costs to control the blowout and return to production
will aggregate approximately $42 million.  During the second quarter of 1997,
the Company recorded a provision of approximately $2.8 million to reserve for
losses that may result from certain costs that may not be recoverable through
insurance, including a $350,000 deductible amount.  At this stage of the
Company's insurance claim, it is not possible to quantify what other amounts,
if any, will not be recoverable from insurance or legally responsible third
parties.  If the Company is unable to recover a significant portion of its
costs from insurance or other third parties, the additional loss associated
with the blowout could be substantial and could have a material adverse effect
on the Company's financial condition and results of operations. 

     As of September 30, 1997, costs incurred for the recovery effort at East
Cameron Block 328 totaled approximately $31.0 million, approximately $16.5
million of which has been reimbursed by insurance companies as of September
30, 1997.  The balance is reflected as a current asset on the accompanying
condensed consolidated balance sheet based on the expectation that such costs
will be collected through insurance within one year.  See also Note 4.

     The Minerals Management Service ("MMS"), which has jurisdiction over
operations in federal waters, is required by regulation to investigate this
type of incident and to make a public report.  To date, the MMS has not issued
any report regarding the blowout.

(4)  DEBT

     As of September 30, 1997, outstanding bank debt totaled $76 million.  The
Company borrowed a net amount of $15 million under its bank credit facility
during the third quarter of 1997 primarily to provide interim funding for the
costs of the recovery from the blowout at East Cameron Block 328, as discussed
in Note 3.  The Company's borrowing base under the bank credit facility was
$86 million.

(5)  LIQUIDATION OF NYLOG PROGRAMS

     During May 1997, the Company completed the liquidation of certain limited
partnerships for which subsidiaries of the Company and of New York Life
Insurance Company ("New York Life") had served as managing general partners
(the "NYLOG Programs").  Under the terms of an indemnity agreement between the
Company and another subsidiary of New York Life, the Company received from
that subsidiary a cash payment of $2.5 million upon the liquidation of the
NYLOG Programs.  Such payment was made in consideration of certain remaining
contingent liabilities of the NYLOG Programs being borne by the managing


   9
                         AMERICAN EXPLORATION COMPANY
        CONDENSED NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (continued)


general partners under the terms specified in the indemnity agreement, as
previously reported.  Although no assurance can be given regarding the
ultimate outcome of the matters underlying such contingencies, the Company
anticipates that the costs, if any, to resolve these matters will not have a
material adverse effect upon the financial condition of the Company.  The $2.5
million receipt was recorded as a deferred credit and was included in other
liabilities on the accompanying condensed consolidated balance sheet as of
September 30, 1997.

(6)  DERIVATIVES

     The Company periodically enters into commodity price swap agreements,
collar transactions and floor transactions that have been designated as hedge
transactions in order to reduce the Company's exposure to market price risk
related to the sale of oil and gas production.  The oil and gas price
references upon which these transactions are based reflect various market
indices that provide a high degree of correlation with actual commodity prices
realized by the Company.  Accordingly, these transactions are accounted for
using the hedge accounting method.  Gains or losses on these transactions are
reported as a component of oil and gas sales in the period during which the
related production occurs.  The cost to purchase put options in connection
with floor transactions is recognized ratably over the term of the agreement
as a reduction of oil and gas revenues.  The Company typically enters into
hedging agreements with a contract term of one year or less.  In the event of
a loss of correlation between changes in the oil and gas price references
under the hedge contract and the actual price realizations for the related oil
and gas production, a gain or loss would be recognized in the current period
to the extent that the hedge contract had not offset changes in actual oil and
gas prices.

(7)  CASH FLOW INFORMATION

     Net cash provided by operating activities included cash payments for
interest totaling $2.7 million and $1.9 million, net of capitalized interest
of $1.9 million and $1.5 million, for the first nine months of 1997 and 1996,
respectively.  The Company paid state income taxes of $.2 million during the
first nine months of 1997.  No income taxes were paid by the Company in the
first nine months of 1996.

(8)  CONTINGENCIES

     In February 1995, a lawsuit was filed in the United States District Court
in Denver, Colorado, by KN Gas Supply Services, Inc. ("KNGSS"), requesting
declaratory judgment that KNGSS had the right to reduce the contract price for
gas produced from the Bowdoin Field to market levels from October 1, 1993
forward.  KNGSS also requested declaratory judgment that it has a right to
relief from the contract price due to regulatory changes, which it alleges
renders the contract commercially impracticable, and that Federal Energy


  10
                         AMERICAN EXPLORATION COMPANY
        CONDENSED NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (continued)


Regulatory Commission Order No. 636 is a condition subsequent which excuses
performance under the contract.  In April 1995, the Company filed
counterclaims against KNGSS relating to the failure of KNGSS to take and pay
for certain minimum volumes of gas, among other contractual matters.  The
Company has dismissed all of its counterclaims, and KNGSS has dismissed its
commercially impracticable and condition subsequent claims.  KNGSS alleges
that it has overpaid the Company and seeks a refund of approximately $7.7
million for the period through September 1996.  KNGSS has not updated its
refund claim through the present date.  A motion for summary judgment
was filed by the Company in July 1996 and was argued before the court on
February 14, 1997.  The court has not yet ruled on the Company's motion. 
Although the Company cannot predict the outcome of this proceeding, American
will vigorously defend its interests in this case and does not expect the
outcome of the case to have a material adverse impact on its financial
position or results of operations.

     The Company has received certain preliminary and one final royalty
underpayment determinations from the Minerals Management Service ("MMS")
aggregating approximately $2.8 million plus interest in connection with
certain gas contract settlements made in prior years.  The Company disagrees
with the MMS determinations and intends to vigorously defend its position in
each case.  In certain cases, the Company's exposure to additional royalty
payment may be limited by indemnity provisions contained in the respective gas
contract settlement agreement.  The amount of any royalty and interest which
ultimately may be paid by the Company attributable to such determinations is
unknown; however, the Company does not expect the outcome to have a material
adverse effect on its financial position or results of operations.

NOTE 1 -- BASIS OF PRESENTATION

     On June 24, 1997, LDNG entered into a Merger Agreement pursuant to which
American was merged into LDNG on October 14, 1997.  The Merger was accounted
for using the purchase method of accounting.  In accordance with the Merger
Agreement, holders of American Common Stock received .72 shares of LDNG Common
Stock and $3.00 cash for each share of American Common Stock.  Holders of
American Depositary Shares received one share of LDNG Depositary Shares of
each share of American Depositary Shares.

NOTE 2 -- PRO FORMA ENTRIES

PRO FORMA BALANCE SHEET -- SEPTEMBER 30, 1997
     The accompanying unaudited pro forma balance sheet as of September 30,
1997 has been prepared as if the Merger had occurred on that date and includes
the following adjustments:

  (a)  To adjust assets and liabilities under the purchase method of
       accounting based on the purchase price.  Such purchase price has been
       allocated to the consolidated assets and liabilities of American based
       on preliminary estimates of fair values with the remainder allocated
       between proved and unproved properties based on their relative fair
       values.  The purchase price allocated to proved properties was further
       allocated based on the relative fair values of individual producing
       fields.  This allocation was then reviewed for indications of 
       impairment by comparing the allocated cost to the estimated
       undiscounted future net cash flows on a field by field basis.  Those
       oil and gas properties having a carrying value in excess of the
       estimated undiscounted future net cash flows were deemed impaired
       pursuant to SFAS 121.  The purchase price allocated to unproved oil and 
       gas properties was adjusted to the lower of cost (allocated purchase
       price) or estimated market value.  The combined impairment resulted in
       a pretax charge of $72.9 million ($45.2 million after tax).  No
       goodwill was recorded in connection with this transaction.  The
       information presented herein is based on historical information as of
       September 30, 1997 and as a result will differ from the actual purchase
       price allocation recorded in the fourth quarter of 1997.

  (e)  To record the estimated adjustment to depreciation, depletion and

       attributable to borrowings made to fund the Cash Consideration at
