WHEREAS,
there is reserved to the Board of Directors of Ocean Energy, Inc. (the
Board) in Section 7 of the Ocean Energy, Inc. Long-Term Incentive
Plan for Nonexecutive Employees (the Plan) the right to amend the
Plan:

WHEREAS,
the Board desires to amend the Plan;

NOW,
THEREFORE, effective immediately, the Plan is amended as follows:

1. Section 2 of
the Plan shall be amended by substituting the following definitions for the following
terms:

Committee
shall mean a committee of the Board consisting only of members thereof appointed
by the Board to administer the Plan. Such committee may delegate its authority
under the Plan to one or more directors and/or executive officers of the Company
to the fullest extent permitted by applicable law. No member of such committee
may be an Employee as defined herein.

Shares
or Common Shares or Common Stock shall mean the common
stock of the Company, $0.10 par value, and such other securities or property as
may become the subject of Awards of the Plan.

2. Section 4(a)
of the Plan shall be deleted and the following shall be substituted therefor:

| | (a)
     Shares Available. Subject to adjustment as provided in Section 4(c), the
     number of Shares with respect to which Awards may be granted under the Plan
     shall be 2,800,000; provided, however, if as of any January 1 the number of
     Shares that are available for Awards under the Plan is less than 2,800,000
     Shares, the maximum number of Shares available for Awards shall be increased
     automatically on such January 1, by the number of Shares necessary to equal
     2,800,000 Shares available for Awards. If any Shares covered by an Award granted
     under the Plan, or to which such an Award relates, are forfeited, or if an Award
     otherwise terminates or is canceled without the delivery of Shares or of other
     consideration, then the Shares covered by such Award, or to which such Award
     relates, or the number of Shares otherwise counted against the aggregate number
     of Shares with respect to which Awards may be granted, to the extent of any such
     forfeiture, termination or cancellation, shall again be, or shall become, Shares
     with respect to which Awards may be granted, but only if, and to the extent
     that, the number of Shares then available for Awards does not exceed 2,800,000
     Shares.
