REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
To the Retirement Committee
of the American Exploration 401(k) Plan:
We have audited the accompanying statements of net assets available for
benefits of the American Exploration 401(k) Plan as of October 14, 1997 and
December 31, 1996, and the related statement of changes in net assets available
for benefits for the period from January 1, 1997 through October 14, 1997. These
financial statements and the schedules referred to below are the responsibility
of the Retirement Committee. Our responsibility is to express an opinion on
these financial statements and schedules based on our audits.
We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
In our opinion, the financial statements referred to above present
fairly, in all material respects, the net assets available for benefits of the
American Exploration 401(k) Plan as of October 14, 1997 and December 31, 1996,
and the changes in net assets available for benefits for the period from January
1, 1997 through October 14, 1997, in conformity with generally accepted
accounting principles.
Our audits were made for the purpose of forming an opinion on the basic
financial statements taken as a whole. The supplemental schedules of reportable
transactions for the period from January 1, 1997 through October 14, 1997,
included as Schedule I and II, are presented for purposes of additional analysis
and are not a required part of the basic financial statements but are
supplementary information required by the Department of Labor's Rules and
Regulations for Reporting and Disclosure under the Employee Retirement Income
Security Act of 1974. The fund information included in the statements of net
assets available for benefits and the statement of changes in net assets
available for benefits is presented for purposes of additional analysis rather
than to present the net assets available for benefits and changes in net assets
available for benefits of each fund. The supplemental schedules and fund
information have been subjected to the auditing procedures applied in the audit
of the basic financial statements and, in our opinion, are fairly stated in all
material respects in relation to the basic financial statements taken as a
whole.
As discussed in Note 1, effective October 14, 1997, American Exploration
Company elected to merge the American Exploration 401(k) Plan into the Louis
Dreyfus Natural Gas Corp. Profit Sharing and 401(k) Plan.

AMERICAN EXPLORATION 401(k) PLAN
NOTES TO FINANCIAL STATEMENTS
(1) DESCRIPTION OF THE PLAN
The following description of the American Exploration 401(k) Plan (the
"Plan") provides only general information. Participants should refer to the Plan
Agreement for a more complete description of the Plan's provisions.
GENERAL
The Plan was a defined contribution plan established effective January
1, 1989. The Plan was established to provide eligible employees with a
convenient way to save on a regular and long-term basis through investment in
various types of accounts.
In connection with the merger of American Exploration Company and Louis
Dreyfus Natural Gas Corp., the Plan merged into the Louis Dreyfus Natural Gas
Corp. Profit Sharing and 401(k) Plan ("New Plan"), effective October 14, 1997.
All investments,except American Exploration Company common stock, were
liquidated prior to the transfer of funds to the New Plan. The American
Exploration Company common stock was transferred in-kind to the New Plan. Each
share of American Exploration Company common stock was converted into .72 of a
share of Louis Dreyfuss Natural Gas Corp. common stock plus $3.00 in cash. The
transferred funds were then reinvested based on employee election forms for the
New Plan.
ELIGIBILITY
Prior to January 1, 1997, only salaried employees were eligible to
participate in the Plan. Effective January 1, 1997, the eligibility requirements
of the Plan were amended to permit all employees who were regularly scheduled to
work at least twenty hours per week to participate in the Plan on the first day
of the month immediately following the employee's date of hire.
EMPLOYEE CONTRIBUTIONS
Employees could make Salary Deferral Contributions to the Plan of up to
15% of the employee's base salary, limited to the maximum total annual
contribution allowed by federal tax laws. These contributions were made through
payroll deductions and were deducted from the employee's salary each pay period
before federal income taxes were withheld. The Plan also provided for Voluntary
Employee Contributions of up to 10% of the employee's base salary. Such
contributions were made with after-tax dollars. However, the aggregate amount of
an employee's Salary Deferral and Voluntary Employee Contributions for any year
could not exceed 15% of the employee's base salary.
An employee's contributions to the Plan may have been invested in one or
in a combination of six mutual funds offered under the Plan. In addition, an
employee may have chosen to invest in the common stock of American Exploration
Company (the "Company"). An employee may have, at any time, changed the mix of
his existing investments or changed the investments in which future
contributions were placed.
EMPLOYER CONTRIBUTIONS
The Company provided Matching Contributions to the employee's account of
$1.00 for each $1.00 of Salary Deferral Contributions, up to a maximum annual
Matching Contribution. Effective January 1, 1997, the Plan was amended such that
the limit on the Company's annual Matching Contribution was increased to 5% of
the employee's base salary or $7,500, whichever was less. These contributions
were made in the form of common stock of the Company.

<PAGE> 7
(1) DESCRIPTION OF THE PLAN (Continued)
The Company could also provide Discretionary Employer Contributions,
which were allocated to each employee's account based upon the ratio of each
employee's base salary to the total base salaries paid to all employees
participating in the Plan. There were no Discretionary Employer Contributions
during 1997.
ALLOCATION OF EARNINGS
Earnings or losses of the Plan's investments were allocated daily to
participants' accounts.
VESTING
Participating employees were always fully vested in all employee and
employer contributions, and such amounts could not be forfeited for any reason.
DISTRIBUTION OF BENEFITS
An employee, or the employee's beneficiary, was entitled to receive a
single lump sum distribution of the employee's account balance upon the
occurrence of any of the following events: termination of employment with the
Company, death or permanent disability of the employee, retirement or attainment
of the age of 59 1/2.
TERMINATION
The Employer could terminate, amend or modify the Plan at its option. If
the Plan were to be terminated, then after the payment of expenses, any
unallocated contributions, income and expenses would be allocated among the
members' accounts.
EMPLOYEES' RIGHTS
Employees could make withdrawals from their accounts in the event of
immediate and significant financial need based on the provisions of the Plan.
Employees could also borrow from their accounts subject to various legal
requirements regarding, among other things, the amount of the loan, the interest
rate to be charged and repayment terms. The rate of interest that was charged on
a loan was the current Prime Rate plus 1%.
As required by federal tax laws, the Plan was subject to certain
limitations on contributions by highly compensated employees, as defined under
such laws. Such limitations were designed to protect the rights of other
employees. There was no liability to refund employee contributions to highly
compensated employees at October 14, 1997 or December 31, 1996.
In addition, the sum of amounts contributed to each of a participant's
accounts in all of the Company's defined contribution plans could not exceed the
lesser of $30,000 or 25% of such participant's compensation. There was no
liability to refund employee contributions due to the effect of this provision
at October 14, 1997 or December 31, 1996.
The Plan was also subject to certain provisions which became effective
if more than 60% of the present value of its total assets were allocated to the
accounts of key employees, as defined under federal tax laws. There were no
restrictions due to these "top-heavy" provisions during 1997 or 1996.

(2) SUMMARY OF ACCOUNTING POLICIES
BASIS OF ACCOUNTING
The financial statements are presented on the accrual basis of
accounting. The investments of the Plan are stated at fair value based on
published closing quotations as of the end of the period. The Stable Value Fund,
which is a common collective trust, is valued at $1 per unit. This fund invests
a substantial portion of its assets in Guaranteed Investment Contracts which are
fully benefit-responsive and for which the contract value generally reflects
fair value. Through October 14, 1997, the year-to-date rate of return for the
Stable Value Fund was 4.6%. As of December 31, 1996, the annual rate of return
for the Stable Value Fund was 6.09%. Participant loans were valued at their
principal amounts which approximate market. Net appreciation (depreciation) in
the fair value of investments consists of realized and unrealized gains (losses)
from investments.
USE OF ESTIMATES
The preparation of financial statements in accordance with generally
accepted accounting principles requires management to make estimates and
assumptions which affect the reported amounts of net assets available for
benefits at the date of the financial statements and the reported amounts of
changes in such net assets during the reporting period. Actual results could
differ from those estimates.
(3) FEDERAL INCOME TAX STATUS
The Plan obtained its latest determination letter on April 29, 1995, in
which the Internal Revenue Service stated that the Plan was in compliance with
the applicable requirements of the Internal Revenue Code. The Plan has been
amended since receiving the latest determination letter. However, the Plan
administrator believes that the Plan was designed and being operated in
compliance with the applicable requirements of the Internal Revenue Code.
Therefore, the Plan administrator believes the Plan was qualified and the
related trust was tax-exempt as of the financial statement dates.
(4) ADMINISTRATION
The Plan was administered by the Retirement Plan Committee appointed by
the Board of Directors of the Company. The Plan trustee was T. Rowe Price Trust
Company. All administrative expenses of the Plan were borne entirely by the
Company.
