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. 11 LOUIS DREYFUS NATURAL GAS CORP.

NOTES TO UNAUDITED PRO FORMA FINANCIAL STATEMENTS 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.
