<PAGE>

         3.01 ESTABLISHMENT Of AMI: The Parties hereby establish and create an
AMI, which shall be defined as the area lying within the red outline, as set
forth on Exhibit "A" hereto, covering approximately 8,427 acres.

         The following four classes of Acreage comprise the AMI:

         "CLASS 1": ANEC's "Bayou Couba Lease" on ExxonMobil's Bayou Couba fee
                    acreage contributing approximately 1319 acres.
         "CLASS 2": ExxonMobil's unleased fee acreage contributing
                    approximately 3,240 acres to the AMI. ExxonMobil shall
                    reserve a 25% royalty interest on all production
                    attributable to its unleased fee acreage in addition to its
                    rights to participate to earn up to 50% of 8/8ths working
                    interest in the proceeds of production for Drilling
                    Prospects developed pursuant to this Agreement.
         "CLASS 3": ANEC's State Lease No. 17353 contributing approximately
                    1,491 acres to the AMI.
         "CLASS 4": Currently unleased State and private acreage comprising
                    approximately 2,377 acres. If ANEC acquires any interest in
                    any oil and gas leases, farmouts, options, assignments or
                    other contractual rights in this acreage, the cost and
                    burdens associated with such acquisition shall be the sole
                    responsibility of ANEC and ExxonMobil shall have no
                    obligation in connection with any such acquisition. ANEC or
                    ExxonMobil may generate prospects for drilling opportunities
                    within such acquired Acreage and ExxonMobil will be entitled
                    to participate to earn up to 50% of 8/8ths working interest
                    in the proceeds of production for Drilling Prospects
                    developed pursuant to this Agreement.

         3.02 NO CROSS-ASSIGNMENT: The Parties hereby agree there shall be no
cross assignment of interests between ExxonMobil and ANEC affecting Acreage
subject to the AMI.

         3.03 BURDENS: ANEC acknowledges that its working interest in the
acreage it is committing or may subsequently acquire in the AMI may be less than
100%, and furthermore that its working interest in the AMI is burdened by
overriding royalty interests, net profits interests, production payments and/or
other burdens on production. The Parties hereto agree that ExxonMobil's working
interest and royalty share of production from the AMI shall be free and clear of
any such burdens, and all such burdens shall be borne solely by ANEC's share of
production developed under the AMI.

         3.04 INDEMNITY: The Parties agree that each Party is solely responsible
for its own lease obligations, royalties, overriding royalties and other burdens
as described in Section 3.03. The Party so burdened shall assume and alone bear
all obligations and shall indemnify, defend, protect and hold the other harmless
(including all costs and attorneys' fees) from all claims, demands, and causes
of action filed by any party related to any alleged interest in production from
the AMI.

                            OPERATIONS WITHIN THE AMI

         4.01 PROPOSED AMI DRILLING PROSPECTS: During the term of this Agreement
ANEC and ExxonMobil agree as follows with respect to each drilling opportunity
within the AMI:

                  (a) Either Party may propose Drilling Prospects. Such a
         Drilling Prospect shall be presented by Notice to the other Party for
         review. Upon receipt of the Notice, such Party shall have a period of
         sixty (60) calendar days (the "election period"), from its receipt of
         such Notice, to elect to participate in the Drilling Prospect by
         delivering written notice of such election to the proposing Party.
         (Failure to respond within the election period shall be deemed an
         election to not participate in such Drilling Prospect.) ExxonMobil's
         election to participate shall also contain an election as to the
         undivided percentage of the Drilling Prospect which ExxonMobil has
         opted to take, if any, provided such percentage may not exceed fifty
         percent (50%) of 8/8ths working interest in the proceeds of production
         from the Drilling Prospect.

                  (b) If either Party timely notifies the proposing Party of its
         election to participate in such Drilling Prospect, such Party shall be
         responsible for its proportionate share of all drilling and completion
         costs incurred in connection with the drilling of the Drilling Prospect
         in which such Party has elected to participate, and operations shall
         proceed pursuant to section 4.04 of this Article IV.

         4.02     ALLOCATION OF PROCEEDS AND EXPENSE:

                  (a) PROCEEDS. In the event ExxonMobil elects to participate in
         a Drilling Prospect, whether such Drilling Prospect contains Acreage
         from Class I, Class II, Class III, Class IV or any combination thereof,
         it shall have the right to participate to earn up to 50% of 8/8ths
         working interest in the proceeds of production from Drilling Prospects
         developed under this Agreement under terms as set forth herein.

                  (b) LIABILITY OF PARTIES: The liability of the Parties shall
         be several, not joint or collective. Subject to the provisions of this
         Agreement and each AMI JOA, each Party shall be responsible only for
         its obligations, and shall be liable only for its share of the costs of
         developing, operating, and abandoning the Drilling Prospect which shall
         be in the same proportion as its working interest share of the proceeds
         of production from the Drilling Prospect.

         4.03 ELECTION NOT TO PARTICIPATE: In the event either Party elects or
is deemed not to have elected to participate in a Drilling Prospect affecting
one or more of the four classes of Acreage contributing to the AMI, the
proposing party shall have 150 days from the end of the election period within
which to commence drilling operations on the


                                       5
<PAGE>

Drilling Prospect. If the proposing party fails to commence drilling operations
as aforesaid or the well drilled fails to produce oil and/or gas in paying
quantities, the Acreage within the Drilling Prospect shall again be subject to
this provision, and any Party wishing to propose a Drilling prospect thereon
must comply with the procedures set forth in Section 4.01. If the proposing
party commences drilling operations as aforesaid, the following conditions shall
apply as to the affected Drilling Prospect acreage:

                  (a) EXXONMOBIL'S NON-PARTICIPATION IN THE DRILLING PROSPECT:

                      - Class 4 Acreage: If ANEC has obtained an oil and gas
                        lease, option, farmout, or other contractual interest in
                        this Class 4 Acreage, ANEC may proceed at its own risk
                        and expense, and ExxonMobil has no interest in
                        production attributable to the Drilling Prospect insofar
                        as it affects this Class 4 Acreage.

                  (b) ANEC NON-PARTICIPATION IN THE DRILLING PROSPECT:
                      - Class 1 Acreage: ExxonMobil proceeds at its own risk and
                        expense and ANEC has no interest in Drilling Prospect
                        production attributable to the affected acreage.

                      - Class 3 Acreage: ANEC issues a one-year sublease to
                        ExxonMobil from the surface to the stratigraphic
                        equivalent of the base of the formation into which
                        ExxonMobil completes a well capable of producing oil
                        and/or gas in paying quantities, encompassing solely the
                        area of the Drilling Prospect, reserving to ANEC an
                        overriding royalty interest of thirty percent (30%) less
                        existing lease burdens.
                      - Class 4 Acreage: If ANEC has obtained an oil and gas
                        lease on the affected acreage, it shall issue to
                        ExxonMobil a one-year sublease from the surface to the
                        stratigraphic equivalent of the base of the formation
                        into which ExxonMobil completes a well capable of
                        producing oil and/or gas in paying quantities,
                        encompassing solely the area of the Drilling Prospect,
                        reserving to ANEC an overriding royalty interest of
                        thirty percent (30%) less existing lease burdens.

<PAGE>

         In the event a designated Drilling Prospect encompasses two or more
classes of acreage, then the conditions in a) and b), set forth above, shall be
applied proportionately according to the contribution of each class of acreage
to the Drilling Prospect area.

         4.04 AMI JOA: All Drilling Prospects for which the receiving Party
elects to participate pursuant to Section 4.01 above shall be subject to and
conducted pursuant to a separate operating agreement (the "AMI JOA") in the form
attached hereto as Exhibit "B". Each AMI JOA shall cover only the areal extent
of the Drilling Prospect from the surface to the stratigraphic equivalent of the
base of the formation into which a completion is made resulting in production of
oil and/or gas in paying quantities. ANEC shall be designated operator under
each AMI JOA; however, ExxonMobil shall have the right, to be exercised in its
sole discretion at any time, to assume operatorship of any Drilling Prospect(s),
and ANEC shall remain operator of any remaining Drilling Prospects. Each AMI JOA
shall govern all operations within each Drilling Prospect, provided, however, in
the event of a conflict between this Agreement and the AMI JOA, then this
Agreement shall take precedence. Upon termination of this Agreement, the
Operating Agreement shall remain in force.

                                   ARTICLE V.

governmental authority, provided that the governmental authority is requested to
hold such data confidential, and to a "third Party" with whom a Party is engaged
in a bona fide effort to sell, farm out or trade any portion of all of its
interest in the AMI. The Confidential Data made available shall not be removed
from the custody or premises of the Party making such data available. Any third
Party permitted such access shall first agree in writing neither to disclose
such data to others nor to use such data except for the purposes for which it is
disclosed.

         5.03 AFFILIATES: Despite the provisions of section 5.01, there shall be
no requirement for approval with respect to the disclosure of Confidential Data
to Affiliates of the Parties.

otherwise agreed by the Parties. Notwithstanding the provisions of this Section
above, each AMI JOA and the applicable provisions of this Agreement shall remain
in effect with respect to each Drilling Prospect which contains a producing well
for so long as such well continues to produce in paying quantities and the
Drilling Prospect is then abandoned. Furthermore, any Drilling Prospect for
which a drilling or deepening AFE has been executed by the Parties prior to the
date this Agreement terminates shall remain subject to the terms of this
Agreement.

                                  ARTICLE VII.
                    PRODUCTION HANDLING AND GAS LIFT SUPPORT

         7.01 HANDLING OF AMI PRODUCTION: Production developed pursuant to this
Agreement shall, where appropriate and at ExxonMobil's option, be handled
through ANEC's Bayou Couba facilities. When ExxonMobil has a working interest
share of production in a Drilling Prospect, ExxonMobil's share shall be handled
on a throughput basis; i.e., ExxonMobil shall be responsible solely for its
share of facilities operating costs attributable to ExxonMobil's working
interest share of production. ExxonMobil shall not be responsible for any
operating costs for production from Drilling Prospects in which ExxonMobil has
elected not to participate.

         7.02 GAS LIFT SUPPORT: ExxonMobil agrees that for the duration of this
Agreement ANEC may utilize the wellbores of the Waterford #1 Well (Serial No.
056712) and Waterford #2 Well (Serial No. 165206), located on ExxonMobil's fee
acreage solely for gas lift purposes in support of wells on ANEC's Bayou Couba
Lease. ANEC shall assume plugging liability for both the Waterford #1 and #2
well, as well as sole and total abandonment liability for any and all existing

thereof may apply to the Parties hereto with respect to the activities or
operations covered by this Agreement. It is not the intention or purpose of this
