          Offering") in which it will distribute to each holder of Common Stock
          approximately 2.0 transferable subscription rights (the "Rights") for
          each share of Common Stock held, with each Right entitling the holder

                                    SUMMARY

     The following summary is not intended to be complete and is qualified in
all respects by reference to the detailed information appearing elsewhere in
this Proxy Statement and in the annexes attached hereto. Stockholders are urged
to read the entire Proxy Statement including the annexes.

GENERAL

     MOXY is an independent oil and gas company engaged in the exploration,
development and production of oil and natural gas.  The Company's operations are
conducted offshore in the Gulf of Mexico (the "Gulf") and onshore in the Gulf
Coast area.  The Company commenced operations in May 1994 following the
distribution of all of the Company's Common Stock to the stockholders of
Freeport-McMoRan Inc. ("FTX") in order to carry on substantially all of the oil
and natural gas exploration activities previously conducted by FTX. The Company
and its predecessors have conducted exploration, development and production
operations offshore in the Gulf and onshore in the Gulf Coast and other areas
for more than 25 years, which  have provided the Company an extensive geological
and geophysical database and significant technical and operational expertise.

     The Company will have expended essentially all of its capital resources by
the end of 1997 and needs significant additional capital to continue its
exploration activities.  If the stockholders approve the Recapitalization
Proposal, MOXY will immediately undertake the Rights Offering, which will
provide MOXY with sufficient capital to restructure its current exploration and
development operations by implementing the significantly expanded and more
diversified, $200 million multi-year MOXY/FRP Exploration Program, acquiring the
MCN Producing Properties and repay the indebtedness incurred by MOXY under the
MOXY/MCN Program.  In addition, the Rights Offering will permit those
stockholders who wish to do so to maintain their proportionate equity and voting
interest in the Company, subject to the possible effects of the FRP Purchase
Option, by exercising their Rights to purchase additional shares of Common
Stock.

     If the stockholders do not approve the Recapitalization Proposal, none of
the transactions described above will occur, and the Company will need to secure
alternative sources of financing to fund any future exploration and development
activities and its current operations beyond the financing available under the
MOXY/MCN Program.  No assurance can be given that such financing will be
available on acceptable terms, if at all, or that the Company will remain a
viable business entity.

THE SPECIAL MEETING; VOTE REQUIRED

     The Special Meeting will be held on ___________, 1997 at 9:00 a.m., at the
office of the Company, 1615 Poydras Street, New Orleans, Louisiana.  Each share
of Common Stock entitles the holder thereof on the record date to one vote on
each matter submitted to a vote of the stockholders at the Special Meeting.

     The Board of Directors has set ________, 1997 as the record date (the
"Record Date") for determination of stockholders entitled to receive notice of
and to vote at the Special Meeting.  There were _____________ shares of Common
Stock issued and outstanding as of the Record Date.

     The affirmative vote of a majority of the total votes cast with respect to
each Proposal in person or by proxy will be required to approve each of the
Proposals.  Each of the Benefit Plan Proposals is subject to and contingent on
adoption of the Recapitalization Proposal.  See "The Special Meeting - Voting
Procedure."

RECOMMENDATION OF THE BOARD OF DIRECTORS OF MOXY

     THE BOARD OF DIRECTORS HAS CONCLUDED THAT THE RECAPITALIZATION PROPOSAL AND
THE BENEFIT PLAN PROPOSALS ARE IN THE BEST INTERESTS OF MOXY AND ITS
STOCKHOLDERS AND RECOMMENDS THAT THE HOLDERS OF COMMON STOCK VOTE TO APPROVE
EACH PROPOSAL.

     In recommending approval of the Recapitalization Transactions, the Board
considered, among other things: the Company's current liquidity and capital
resources; the Company's ability to increase its proved reserves and cash flow
by acquiring the MCN Producing Properties in which the Company already has an
interest; the need to obtain additional capital to fund the Company's
exploration activities; current exploration and development projects and future
exploration activities; the relative advantages and disadvantages of the
Recapitalization Transactions in comparison to alternative transactions that
might be available to the Company; and the opinion of its independent financial
advisor, Donaldson Lufkin & Jenrette Securities Corporation ("DLJ"), all as more
fully described herein.

OPINION OF INDEPENDENT FINANCIAL ADVISOR

     MOXY has received an opinion from DLJ, its independent financial advisor,
that, as of the date of such opinion, and subject to the assumptions, factors
and limitations set forth in such opinion, the financial terms of the
Recapitalization Transactions are, in the aggregate, fair to the Company and its
stockholders from a financial point of view.

THE RECAPITALIZATION TRANSACTIONS

     Rights Offering. If the stockholders approve the Recapitalization Proposal,
the Rights Offering will commence promptly after the Special Meeting and will
expire not less than 30 days thereafter, subject to extension by MOXY, with
FRP's consent, for up to an additional 30 days (as extended, the "Expiration
Date"). Pursuant to the Rights Offering, the Company will distribute to each
holder of Common Stock, as of the record date for the Rights Offering,
approximately 2.0 Rights for each share of Common Stock held, and each Right
will entitle the holder thereof to receive, upon payment of the Subscription
Price, one share of Common Stock (the "Basic Subscription Privilege"). In
addition, each Right will carry the right (the "Oversubscription Privilege") to
subscribe at the Subscription Price for additional shares of Common Stock not
subscribed for by other holders through the exercise of the Basic Subscription
Privilege (the "Excess Shares").  Only holders who exercise the Basic
Subscription in full will be entitled to exercise the Oversubscription
Privilege.  If the Excess Shares are insufficient to satisfy all subscriptions
pursuant to the Oversubscription Privilege, the Excess Shares will be allocated
pro rata among those holders who exercise the Oversubscription Privilege in
proportion to the number of shares each holder subscribed to pursuant to the
Basic Subscription Privilege; provided, however, that no holder will be
allocated more shares than such holder has subscribed for pursuant to the
exercise of the Oversubscription Privilege. Once a holder has exercised the
Basic Subscription Privilege or the Oversubscription Privilege, such exercise
may not be revoked.

     Once distributed and until the Expiration Date, the Rights will be freely
transferable.  It is expected that the Rights will trade on the Nasdaq National
Market (the "Nasdaq") under the symbol "MOXYR" until the close of business on
the last Nasdaq trading day prior to the Expiration Date.  See "The
Recapitalization Transactions - The Rights Offering."

     Standby Commitment.  Pursuant to, and subject to the terms and conditions
contained in, the Standby Purchase Agreement, FRP will purchase at the
Subscription Price all of the shares of Common Stock that are offered but not
purchased in the Rights Offering.  FRP may also purchase Rights on the open
market and exercise such Rights prior to the Expiration Date.

                                       2
<PAGE>
 
     It is anticipated that MOXY will issue approximately 28.6 million shares of
Common Stock for an aggregate of approximately $100 million pursuant to the
Rights Offering and the Standby Commitment.

     FRP Purchase Option.  The Standby Purchase Agreement also provides FRP with
an option (the "FRP Purchase Option") to purchase at the Subscription Price such
additional shares of Common Stock as are necessary to provide it with up to a
30% ownership interest in MOXY after giving effect to the completion of the
Rights Offering and the purchase of shares pursuant to the Standby Commitment
and the FRP Purchase Option.  See "The Recapitalization Transactions - The
Standby Purchase Agreement"  and "Potential Effects of the Recapitalization
Transactions on Control of MOXY."

     Stockholder Agreement.  MOXY and FRP have also agreed to enter into an
agreement (the "Stockholder Agreement") pursuant to which (i) MOXY will
implement certain corporate governance measures designed to protect the
stockholders of MOXY other than FRP, (ii) FRP will have the ability to designate
a certain number of directors if it owns more than 10% but less than a majority
of the outstanding Common Stock and (iii) MOXY will grant certain registration
rights to FRP with respect to the shares of Common Stock that FRP may acquire
pursuant to the Standby Commitment and the FRP Purchase Option.  See "The
Recapitalization Transactions - Stockholder Agreement; Registration Rights."

     Purchase of the MCN Producing Properties; Repayment. In July 1997, FRP
agreed to acquire from MCN its interests in the MOXY/MCN Program, the MCN
Producing Properties and other exploratory properties acquired under the
MOXY/MCN Program for $31.0 million, as adjusted for the net revenues and
development and operating costs of such properties from April 1, 1997 until
their acquisition by FRP, and an additional amount equal to the amount loaned by
MCN to MOXY under the MOXY/MCN Program. On __________, 1997, FRP paid MCN, after
adjustments, $_______ for such assets together with $_______ for the outstanding
indebtedness.

     MOXY and FRP have amended the MOXY/MCN Program to extend the program term,
include their interests in the seven offshore leases acquired by MOXY and FRP at
the Central Gulf of Mexico lease sale held in March 1997 and provide for the
conduct of mutually agreed exploration projects until the earlier of 
December 31, 1997 or, if the Recapitalization Proposal is approved at the
Special Meeting, until the date of the completion of the Rights Offering. The
amendment also provided that FRP will reimburse MOXY for approximately $290,000
of overhead costs per month and will continue to advance funds to MOXY under the
MOXY/MCN Program during the remaining program term.

     Upon completion of the Rights Offering and the transactions contemplated by
the Standby Purchase Agreement, MOXY will acquire the MCN Producing Properties
from FRP (the "MCN Purchase") for $26.0 million, subject to the adjustments
described above with respect to revenues and costs attributable to the MCN
Producing Properties  from April 1, 1997 until their acquisition by MOXY plus
interest, calculated on the daily outstanding balance of the $26.0 million
purchase price, as adjusted, from ______, 1997 until MOXY's acquisition of the
properties at an annual rate publicly announced by The Chase Manhattan Bank from
time to time plus 2%.  At the same time, MOXY will repay to FRP all amounts
advanced to MOXY under the MOXY/MCN Program.  Thereafter, MOXY will retain a
100% interest in the MCN Producing Properties and MOXY and FRP will dedicate to
the MOXY/FRP Exploration Program all other oil and gas properties then subject
to the MOXY/MCN Program.

     MOXY/FRP Exploration Program.  Upon completion of the Rights Offering and
closing of the MCN Purchase, MOXY and FRP will terminate the amended MOXY/MCN
Program and enter into the MOXY/FRP Exploration Program.  MOXY will manage the
MOXY/FRP Exploration Program, selecting all prospects and drilling
opportunities, and will serve as operator of all wells drilled by the MOXY/FRP
Exploration Program. MOXY and FRP will commit $200 million for exploration
expenses to be incurred under the MOXY/FRP Exploration Program, with exploration
expenses being shared 40% by MOXY and 60% by FRP.  All revenues and other costs
will be shared equally.  The MOXY/FRP Exploration Program will terminate upon
the earlier 

                                       3
<PAGE>
 
to occur of the commitment of $200 million for exploration expenses or June 30,
2002. See "The Recapitalization Transactions - The MOXY/FRP Exploration
Program."

POTENTIAL EFFECTS OF THE RECAPITALIZATION TRANSACTIONS ON CONTROL OF MOXY

     The purchase by FRP of shares of Common Stock pursuant to the Standby
Commitment or the FRP Purchase Option could result in FRP becoming MOXY's
largest stockholder and being in a position to control or significantly
influence the business operations and policies of the Company.  In particular,
if less than approximately 25% of the Rights are exercised by holders, then
pursuant to the Standby Commitment, FRP will obtain a majority of the
outstanding shares of Common Stock and will have the power to control the
election of the Company's directors and otherwise to direct the business
policies of the Company.  Moreover, if a large number of shares are issued
pursuant to the exercise of Rights such that FRP does not acquire through the
Standby Commitment at least 30% of the MOXY Common Stock outstanding after
giving effect to the Rights Offering and the Standby Commitment, FRP may
purchase such number of additional shares at the Subscription Price to provide
it with a 30% ownership interest in the Company.   MOXY has agreed to give FRP
the right, for as long as FRP owns at least 10% but less than a majority of the
outstanding Common Stock, to designate a number of members of the Board of
Directors proportionate to its ownership percentage of the outstanding Common
Stock.  In connection with these transactions, MOXY has also amended its Rights
Agreement (the "Rights Plan") to exempt FRP from its application.  See "The
Recapitalization Transactions -Potential Effects of the Recapitalization
Transactions on Control of MOXY."

     The Stockholder Agreement also provides that, as long as FRP owns at least
10% of the outstanding Common Stock, MOXY will not, without the approval of a
committee composed of independent members of the Board of Directors (the
"Independent Committee"), take certain actions, including, among other things,
purchases of Common Stock, certain transactions with FRP involving aggregate
payments in excess of $5 million, "going private" transactions and mergers and
other business combinations with FRP or its affiliates. See "The
Recapitalization Transactions - The Stockholder Agreement; Registration Rights."

INTERESTS OF CERTAIN PERSONS IN THE RECAPITALIZATION TRANSACTIONS

     All of the directors who currently serve on the Company's Board of
Directors also serve on the Board of Directors of FTX, which owns a 51.6%
interest in, and serves as the administrative managing general partner of, FRP.
In addition, certain executive officers of the Company also serve as executive
officers of FRP and/or FTX.  See "The Recapitalization Transactions - Interests
of Certain Persons in the Recapitalization Transactions" and "Certain
Relationships and Related Transactions."

CONSEQUENCES IF THE RECAPITALIZATION PROPOSAL IS NOT APPROVED

     If the stockholders do not approve the Recapitalization Proposal, the
Recapitalization Transactions will not be completed, FRP will retain its
interest in the MOXY/MCN Program, the MOXY/FRP Exploration Program will not be
established and the expanded exploration activities contemplated thereby will
not be undertaken.  FRP will have the obligation to fund, and extend credit to
MOXY to fund, any exploration and development costs that may be committed under
the amended MOXY/MCN Program and any other amounts that may be borrowed by MOXY
thereunder with respect to the properties then subject to the MOXY/MCN Program.
FRP will not be obligated to fund any other exploratory prospects.

     As a result, MOXY will be forced to secure alternative sources of financing
to support its current operations and fund any future exploration and
development activities beyond the financing available under the MOXY/MCN
Program.  All of the net revenues generated from MOXY's producing oil and gas
properties are dedicated to repay indebtedness incurred under the MOXY/MCN
Program.  Such alternative sources could include additional equity or debt
financing, the sale of all or part of MOXY's assets or other partnership or
joint venture transactions.  There can be no assurance that alternative
financing will be available on 

                                       4

acceptable terms, if at all, or that the Company will be a viable business
enterprise. See "The Recapitalization Transactions - Consequences if the
Recapitalization Proposal is Not Approved."

     The Company's business strategy is to create value for its stockholders
through the discovery of oil and gas reserves in its exploration and development
activities.  If the Recapitalization Transactions are not approved at the
Special Meeting, MOXY will be forced to seek alternatives to the MOXY/FRP
Exploration Program.  Rejection of the Recapitalization Transactions will not
prohibit the Company from entering into other exploration programs or  joint
ventures, including those with FRP or any other party, and with any financial
commitment that the Company deems appropriate.

ADVANTAGES AND DISADVANTAGES OF THE RECAPITALIZATION TRANSACTIONS

     The principal advantages that the Board believes will result from the
Recapitalization Transactions are (i) a substantial improvement in MOXY's
capital structure and an increase in its liquidity through the substantial
increase in its invested equity capital, (ii)  the ability to continue and
substantially expand MOXY's exploration program and manage drilling risk through
participation in an increased number of drilling prospects, (iii) the increase
in proved reserves and cash flow from purchasing the MCN Producing Properties in
which MOXY currently has an interest, (iv) the ability of MOXY's current
stockholders who wish to do so to maintain or increase their proportionate
equity and voting interest in the Company, subject to the possible effects of
the FRP Purchase Option, by exercising their Rights to purchase additional
shares of Common Stock pursuant to the Basic Subscription Privilege and the
Oversubscription Privilege, (v) the ability of stockholders who do not wish to
purchase additional shares of Common Stock to transfer and thereby receive the
market value of Rights and (vi) the ability of MOXY's current stockholders to
participate in any long term benefits received in connection with MOXY's
existing exploration activities and the MOXY/FRP Exploration Program.

     The principal disadvantage of the Recapitalization Transactions that was
considered by the Board was the potential dilution of the equity interests of
existing stockholders who do not choose to exercise their Rights.  The Board
also considered (i) the potential dilutive effect of the FRP Purchase Option to
current stockholders and (ii) the potential transfer of control of MOXY to FRP
as a result of the Recapitalization Transactions.  See "The Recapitalization
Transactions - Advantages and Disadvantages of the Recapitalization
Transactions."

NEW BENEFIT PLAN PROPOSALS

     The Board of Directors is seeking stockholder approval of amendments to two
benefit plans, which are described in more detail under "Proposal to Approve
Amendments to the 1994 Stock Option Plan for Non-Employee Directors" and
"Proposal to Approve Amendments to the 1994 Stock Option Plan."  The Benefit
Plan Proposals are subject to stockholder approval as well as stockholder
approval of the Recapitalization Proposal.

INTENTION OF EXECUTIVE OFFICERS AND DIRECTORS

     Each executive officer and director of MOXY who owns Common Stock has
indicated that he or she intends to vote in favor of the approval of each of the
Proposals.  As of June 30, 1997, these executive officers and directors owned,
in the aggregate, 1,029,908 shares of the outstanding Common Stock (representing
7.3% of the total outstanding shares).

MARKET PRICE OF THE COMMON STOCK

     The closing sale price of the Common Stock as reported by the Nasdaq
National Market on July 14, 1997 (the last trading day before the announcement
that MOXY and FRP had entered into the Standby 

                                       5

Purchase Agreement) was $3 5/8 per share. On _______, 1997 (the last trading day
before the date of this Proxy Statement), the closing sale price of the Common
Stock was $____ per share.

                              THE SPECIAL MEETING

     This Proxy Statement and accompanying form of proxy have been furnished in
connection with the solicitation of proxies by MOXY's Board of Directors for use
at the Special Meeting. At the Special Meeting, holders of shares of MOXY's
Common Stock will be asked to consider and vote on the Recapitalization Proposal
and each of the Benefit Plan Proposals as described in the cover page of this
Proxy Statement.

     MOXY's Board of Directors is not aware of any other matters to be presented
at the Special meeting. If however, other matters are properly brought before
the Special Meeting, the persons named in the enclosed form of proxy will have
the discretion to vote or abstain from voting according to their best judgment.

VOTING PROCEDURE

     Stockholders of record at the close of business on ________________, 1997
(the "Record Date") will be entitled to vote at the Special Meeting. On the
Record Date, there were __________ shares of Common Stock outstanding.

     The Company's by-laws (the "By-Laws") provide that the holders of a
majority of the shares of Common Stock issued and outstanding and entitled to
vote at the Special Meeting, present in person or represented by proxy, will
constitute a quorum at the Special Meeting. The persons appointed by the Company
to act as inspectors of election will treat shares of Common Stock represented
by a properly executed and returned proxy as present at the Special Meeting for
purposes of determining a quorum. The shares of Common Stock present at the
Special Meeting that abstain from voting or are the subject of broker non-votes
will be counted as present for purposes of determining a quorum.

     The affirmative vote of a majority of the total votes cast with respect to
each Proposal in person or by proxy is required to approve each Proposal.
Except as otherwise provided by statute, the Company's Certificate of
Incorporation (the "Certificate of Incorporation" or "Certificate") or the By-
Laws, all other matters coming before the Special Meeting will be decided by the
vote of a majority of the number of shares of Common Stock present in person or
represented by proxy and entitled to vote at the Special Meeting.  Each share of
Common Stock will entitle the holder to cast one vote at the Special Meeting,
and votes cast will be counted by the inspectors of election. Although broker
non-votes will be counted as present for determining the presence of a quorum at
the Special Meeting, they will not be deemed votes cast with respect to any of
the Proposals, will not count as votes for or against any of the Proposals and
will not be included in calculating the number of votes necessary for approval
of each of the Proposals.

     NONE OF THE PROPOSALS WILL BE IMPLEMENTED UNLESS THE RECAPITALIZATION
PROPOSAL IS APPROVED. HOWEVER, THE IMPLEMENTATION OF THE RECAPITALIZATION
PROPOSAL IS NOT CONDITIONED UPON THE APPROVAL OF THE BENEFIT PLAN PROPOSALS.
ACCORDINGLY, A VOTE AGAINST THE RECAPITALIZATION PROPOSAL WILL GENERALLY HAVE
THE SAME EFFECT AS A VOTE AGAINST ALL OF THE PROPOSALS, BUT A VOTE AGAINST THE
BENEFIT PLAN PROPOSALS WILL NOT AFFECT THE IMPLEMENTATION OF THE
RECAPITALIZATION PROPOSAL.

     Proxies in the enclosed form are solicited by the Board of Directors to
provide an opportunity to every stockholder to vote on the Proposals, whether or
not he or she attends in person. If proxies in the enclosed form are properly
executed and returned, the shares represented thereby will be voted as
specified. If no specifications are made, the proxies will be voted in favor of
the Recapitalization Proposal and each of the Benefit Plan Proposals. Any
stockholder executing a proxy may revoke that proxy or submit a revised proxy at
any time before it is voted. A stockholder may also attend the Special Meeting
in person and vote by ballot, thereby canceling any proxy previously given.
Management does not intend to bring any matters before the Special Meeting other
than the Proposals and does not know of any other matters to be brought before
the Special Meeting by others.

PROXY SOLICITATION

     The Company will pay all expenses of soliciting proxies for the Special
Meeting. In addition to solicitations by mail, arrangements have been made for
brokers and nominees to send proxy materials to their principals, and the
Company will reimburse them for their reasonable expenses in doing so. The
Company has retained Georgeson & Company Inc., Wall Street Plaza, New York, New
York, to assist with the solicitation of proxies from brokers and nominees. It
is estimated that the fees for such firm's services will be $8,000 plus its
reasonable out-of-pocket expenses. Certain employees of the Company, who will
receive no additional compensation for their services, may also solicit proxies
by telephone, telegram, telex, telecopy or personal interview.

STOCKHOLDER PROPOSALS

     In order to be considered for inclusion in the proxy materials for the
Company's 1998 annual meeting of stockholders, stockholder proposals must be
received by the Company no later than November 25, 1997.


                       THE RECAPITALIZATION TRANSACTIONS

     The Recapitalization  Transactions contemplate recapitalizing MOXY through
a series of transactions that, if consummated, would permit MOXY to restructure
its current exploration and development operations and implement a significantly
expanded and more diversified  multi-year exploratory drilling program.

     If the Recapitalization Proposal is approved by MOXY's stockholders at the
Special Meeting, the Company will (i) immediately commence the Rights Offering
by distributing the Rights to its stockholders, (ii) close the Rights Offering
and the transactions contemplated by the Standby Purchase Agreement, subject to
the terms and conditions contained therein, as soon as practicable after the
Expiration Date, (iii) purchase from FRP the MCN Producing Properties and repay
all of the debt incurred under the MOXY/MCN Program and (iv) enter into the
MOXY/FRP Exploration Program. If the Recapitalization Proposal is not approved,
none of the Recapitalization Transactions will take place and MOXY will be
forced to secure alternative sources of financing to support its exploration
activities. There can be no assurance that alternative financing will be
available on acceptable terms, if at all, or that the Company will remain a
viable business enterprise.  See " --Consequences if the Recapitalization
Proposal is Not Approved."

     The following summaries of the Recapitalization Transactions are qualified
in their entirety by reference to, and stockholders are urged to read the
complete text of, the Master Agreement, the Standby Purchase Agreement, the
Stockholder Agreement and the Participation Agreement, which are included as
Annexes I through IV to this Proxy Statement.   The consummation of each of
those agreements and the transactions contemplated thereby are contingent upon
and subject to receipt of stockholder approval of the Recapitalization Proposal
at the Special Meeting.

BACKGROUND AND REASONS FOR THE RECAPITALIZATION TRANSACTIONS

     Since May 1994, when MOXY was spun-off from FTX, MOXY has pursued a
business plan of exploring for and producing oil and gas primarily in the Gulf
and Gulf Coast area. Thus far,  MOXY has identified and has interests in two
producing fields in the Gulf, the Vermilion Block 160 Unit and Vermilion Block
410 field. However, by the end of 1997 MOXY will have expended essentially all
of its capital resources and requires significant additional capital to continue
its exploration activities.  Moreover, MOXY's management and Board of Directors
believe that it is important for MOXY to obtain sufficient capital to enable
MOXY to participate in a broader range of exploration prospects.

     MOXY's management and Board of Directors continue to believe in the
potential of MOXY's exploration and development strategy and the potential for
MOXY to develop additional attractive prospects based on the significant
quantity of geological and geophysical data that MOXY has acquired over the
years and the experience of its exploration team.  Moreover, MOXY believes that
its recent and continuing 

                                       9
<PAGE>
 
acquisitions of 3-D seismic data will continue to improve its ability to
interpret subsurface geology and allow it to develop a larger inventory of high
quality prospects that it can pursue at offshore lease sales and through farm-in
opportunities in areas where it has a substantial geologic database and a long
history of operational experience.

     In order to realize that potential, the Company has considered a number of
strategies for raising additional equity capital.  It has undertaken its recent
business activities through joint venture arrangements, including arrangements
with MCN, Phillips Petroleum and FRP. See "Certain Relationships and Related
Transactions."  However, MOXY has concluded that those and similar joint
ventures will not provide sufficient capital to conduct the type of expanded
exploration program that it believes is needed to take full advantage of MOXY's
geophysical data, explore a larger number of prospects and effectively manage
drilling risk.

     Accordingly, in mid-1996 the Company began to consider a range of strategic
options, including an extension of the MOXY/MCN Program, other joint ventures,
equity offerings and business combinations. Those options ultimately were
rejected, however, because MOXY's management and Board of Directors concluded
that short-term or limited scope joint ventures would not provide sufficient
capital for an expanded program of the size and scope that management and the
Board believed were appropriate and did not believe that MOXY had the financial
resources to engage in strategic acquisitions.   Moreover, the Board believed
that many, and perhaps most, of the Company's stockholders hold its Common Stock
as an exploration investment and would prefer to continue to hold their
investment and participate in MOXY's exploration program rather than to
liquidate their investment, especially if an infusion of additional capital
would increase the number of prospects that MOXY could pursue, thereby enhancing
its opportunities of exploration success while diversifying its exploration
risk.

     The Board of Directors ultimately settled on the Rights Offering, backed up
by the Standby Commitment, as the preferred capital-raising strategy, because it
will provide the capital that MOXY needs to pursue an expanded exploration
program while permitting stockholders to continue to participate in that program
and giving stockholders the opportunity to maintain their proportionate equity
and voting interest in MOXY, subject to the possible effects of the FRP Purchase
Option, by exercising their Rights to purchase additional shares of Common
Stock. Also integral to the Board's decision to pursue the Rights Offering and
the Recapitalization Transactions were the opportunities to acquire the MCN
Producing Properties and to enter into the MOXY/FRP Exploration Program.  These
transactions will give MOXY the critical mass provided by additional proved
reserves and current revenues provided by the MCN Producing Properties and a
significant source of external funding that will permit MOXY to drill a larger
number of exploratory prospects, thereby diversifying its risk, while working
with a knowledgeable partner with which MOXY has a close and longstanding
relationship.

     After carefully weighing the alternatives and considering the advice of
DLJ, the Board has concluded that the Recapitalization Transactions represent
the most effective and equitable means of achieving MOXY's strategic goals and
provides the best opportunity reasonably available to enhance stockholder value.

RECOMMENDATION OF BOARD OF DIRECTORS

     The Board has concluded that the Recapitalization Transactions are in the
best interests of MOXY and its stockholders. Accordingly, the Board unanimously
recommends that the holders of Common Stock vote to approve the Recapitalization
Proposal.

     In recommending approval of the Recapitalization Transactions, the Board
considered, among other things: (i) the Company's current liquidity and capital
resources; (ii) the Company's ability to increase its proved reserves and cash
flow by acquiring the MCN Producing Properties in which the Company already has
an interest; (iii) the Company's need to obtain additional capital to fund
exploration activities; (iv) current exploration and development projects and
future exploration activities in which the Company may participate; (v) the
relative advantages and disadvantages of the Recapitalization Transactions in
comparison to alternative transactions that might be available; and (vi) the
opinion of DLJ described below under "Opinion of Independent Financial Advisor.

                                       10
<PAGE>
 
     The Board considered all of the factors listed above as a whole in reaching
its conclusion to recommend that the stockholders approve the Recapitalization
Transactions and it is impracticable to assign relative weights to the factors
considered.

     THE BOARD OF DIRECTORS HAS APPROVED THE RECAPITALIZATION TRANSACTIONS AND
UNANIMOUSLY RECOMMENDS THAT THE STOCKHOLDERS VOTE "FOR" THE RECAPITALIZATION
PROPOSAL.

OPINION OF INDEPENDENT FINANCIAL ADVISOR

     In its role as financial advisor to the Company, DLJ was asked by the
Company to render an Opinion to the Board of Directors of the Company as to the
fairness to the stockholders of the Company, from a financial point of view, of
the Recapitalization Transactions (as summarized below) contemplated by the
Master Agreement. Pursuant to the Master Agreement, the following transactions
are proposed to be consummated as the Recapitalization Transactions:  (i) FRP
will purchase MCN's interest in the MOXY/MCN Program, the MCN Producing
Properties and other exploratory properties acquired thereunder, (ii) MOXY and
MCN will amend the MOXY/MCN Program Agreement, (iii) MOXY will conduct the
Rights Offering, (iv) FRP will provide the Standby Commitment and receive the
FRP Purchase Option and the fees provided for in the Standby Purchase Agreement,
(v) MOXY and FRP will enter into the Stockholder Agreement, (vi) MOXY will
purchase the MCN Producing Properties from FRP, and (vii) MOXY and FRP will
convey all of the exploration properties dedicated to the MOXY/MCN Program to
the MOXY/FRP Exploration Program and commence operations thereunder pursuant to
the Participation Agreement.  On July 14, 1997, DLJ delivered its opinion to the
Board of Directors of the Company (a copy of which is attached as Annex V to
this Proxy Statement) that, as of the date of the DLJ Opinion, and based upon
and subject to the assumptions, limitations and qualifications set forth in such
opinion, the Recapitalization Transactions are, in the aggregate, fair to the
Company and its stockholders from a financial point of view.

THE FULL TEXT OF THE DLJ OPINION IS ATTACHED TO THIS PROXY STATEMENT AS ANNEX V.
THE DLJ OPINION SHOULD BE READ CAREFULLY IN ITS ENTIRETY FOR ASSUMPTIONS MADE,
MATTERS CONSIDERED AND LIMITS OF THE REVIEW AND PROCEDURES FOLLOWED BY DLJ IN
CONNECTION WITH SUCH OPINION.

     The Board selected DLJ as its financial advisor because it is a nationally
recognized investment banking firm that has substantial experience in the oil
and gas industry and is familiar with the Company and its business.  As part of
its investment banking business, DLJ is regularly engaged in the valuation of
businesses and securities in connection with mergers, acquisitions,
underwritings, sales and distributions of listed and unlisted securities,
private placements and valuations for estate, corporate and other purposes.

     The DLJ Opinion was prepared for the Company's Board of Directors and is
directed only to the fairness of the Recapitalization Transactions, in the
aggregate, to the stockholders of the Company from a financial point of view and
does not constitute a recommendation to any stockholder as to how such
stockholder should vote at the Special Meeting.  The DLJ Opinion does not
constitute an opinion as to the price at which the Common Stock may  trade in
the open market at any time.  No restrictions or limitations were imposed by the
Company upon DLJ with respect to the investigations made or the procedures
followed by DLJ in rendering its opinion.  DLJ was not authorized to, nor did
DLJ, solicit alternative proposals to acquire the Company, although DLJ noted
that consummation of the Recapitalization Transactions could result in a change
of control of MOXY (since, based on participation level of MOXY stockholders in
the Rights Offering, FRP could acquire up to 67% of MOXY's outstanding Common
Stock through the Standby Commitment).

     In arriving at its opinion, DLJ reviewed the Master Agreement and the
exhibits thereto. DLJ also reviewed financial and other information that was
publicly available or furnished to it by the Company, including information
provided during discussions with the Company's management.  Included in the
information provided during discussions with the Company's management were
financial projections of the Company for the period beginning January 1, 1997
and ending December 31, 1998, prepared by the management of the Company.  With
respect to such financial projections, DLJ assumed that they were 

                                       11
<PAGE>
 
reasonably prepared on the basis reflecting the best currently available
estimates and judgments of MOXY's management as to MOXY's future operating and
financial performance. In addition, DLJ compared certain financial and
securities data of the Company with various other companies that DLJ deemed
relevant, reviewed the historical stock prices and trading volumes of the Common
Stock, and conducted such other financial studies, analyses and investigations
as DLJ deemed appropriate for purposes of its opinion. DLJ has not requested to,
nor did DLJ solicit the interest of any other party in acquiring the Company.
DLJ also considered the Company's immediate need for additional cash to fund its
capital, operating and growth requirements, and the limited number of
alternatives available to the Company to obtain additional debt or equity
financing.

     In rendering its opinion, DLJ relied upon and assumed the accuracy and
completeness of all of the financial and other information that was available to
it from public sources, that was provided to it by the Company or that was
otherwise reviewed by it.  DLJ did not make any independent evaluation of the
assets or liabilities of the Company, nor did DLJ independently verify the
information reviewed by it.  DLJ relied as to certain legal matters on advice of
counsel to the Company.

     The DLJ Opinion was necessarily based on economic, market, financial and
other conditions as they existed on, and on the information made available to it
as of the date of, the DLJ Opinion.  It should be understood that, although
subsequent developments may affect its opinion, DLJ does not have any
obligations to update, revise or reaffirm the DLJ Opinion.  The DLJ Opinion does
not address the relative merits of the Recapitalization Transactions or other
business strategies being considered by the Company's Board of Directors, nor
does it address the Board's decision to proceed with the Recapitalization
Transactions.

     DLJ, as part of its investment banking services, is regularly engaged in
the valuation of businesses and securities in connection with mergers,
acquisitions, underwritings, sales and distributions of listed and unlisted
securities, private placements and valuations for estate, corporate and other
purposes.  DLJ has performed investment banking and other services for the
Company, FRP and its affiliates in the past and has received customary
compensation for such services.

     The following is a summary of certain factors considered and financial
analyses performed by DLJ in connection with the DLJ Opinion that were included
in a presentation to the Board of Directors of the Company on July 14, 1997.

     Analysis of Certain Other Publicly Traded Companies.   To provide
contextual data and comparative market information, DLJ compared selected
historical share price, earnings and operating and financial ratios for the
Company to the corresponding data and ratios of certain other companies whose
securities are publicly traded (collectively, the "Comparable Companies").  The
Comparable Companies were chosen because they possess general business,
operating and financial characteristics representative of companies in the
industry in which the Company operates.  The Comparable Companies consisted of:
Bellwether Exploration Company, Callon Petroleum Company, Chieftain
International, Inc., Edge Petroleum Corporation, The Houston Exploration
Company, Offshore Energy Development Corporation, Stone Energy Corporation and
Meridian Resource Corporation.  Such data and ratios included Enterprise Value
("Enterprise Value"  is defined as the product of the stock price and total
shares outstanding ("Equity Value") plus Net Debt ("Net Debt" is defined as
total debt plus preferred stock less cash and cash equivalents)) (i) to 1996-
1998 EBITDAX ("EBITDAX" is defined as earnings before interest, taxes,
depreciation, amortization and exploration expense), (ii) per Mcf of reserves,
and (iii) as a percentage of SEC pre-tax PV-10.  DLJ also examined the ratios of
share price to 1996-1998 earnings per share, 1996-1998 cash flow per share and
current book value per share.  In addition, DLJ examined the ratios of total
debt to total book capitalization, total debt to reserves, and reserves to
production for the Comparable Companies and compared all such ratios with those
of the Company.

     Applying a range of multiples obtained for the Comparable Companies to the
operating data of the Company, this analysis indicated a high and low range of
implied share prices for the Company of between $1.01 to $1.78.  The implied
share prices exclude the impact of values which are less than zero.

                                       12
<PAGE>
 
     Transaction Analysis.   DLJ reviewed publicly available information for 14
selected transactions involving the combination of selected Exploration and
Production companies.  The 14 transactions reviewed (the "Comparative
Transactions") were: Louis Dreyfus Natural Gas Corporation/American Exploration
Company, Forcenergy Inc./Edisto Resources Corporation, Bellwether Exploration
Company/Torch Energy Advisors, Inc., Domain Energy Corporation/El Paso Natural
Gas Company, Lomak Petroleum Inc./America Cometra, Inc., Forcenergy Inc./Great
Western Resources, Inc., KCS Energy, Inc./InterCoast Oil & Gas Company, Noble
Affiliates, Inc./Energy Development Corporation, Enron Capital & Trade
Resources/Hardy Oil & Gas Plc, Hunt Petroleum Corporation/Columbia Gas
Development Corporation, Contour Production Company L.L.C./Kelley Oil & Gas
Corporation, United Meridian Corporation/General Atlantic Resources Corporation,
Burlington Resources, Inc./Maxus Energy Corporation and Cabot Oil & Gas
Corporation/Washington Energy Resources Company.  The 14 transactions selected
are not intended to represent a complete list of Exploration and Production
transactions, rather they include only transactions involving combinations of
companies with operating characteristics, size or financial performance
characteristics which DLJ believed to be comparable to those of the Company.
DLJ reviewed the Enterprise Value of such transactions as a multiple of LTM
EBITDAX, SEC pre-tax PV-10 and oil and gas reserves.  DLJ also reviewed the
stock price paid in such transactions as a multiple of LTM cash flow per share.

     Applying a range of multiples obtained for the Comparative Transactions to
the operating data for the Company, this analysis indicated a high and low range
of implied share prices for the Company of $0.79 to $1.29.  The implied per
share prices exclude the impact of values which are less than zero.

     Valuation Based on Net Asset Value.  DLJ performed a valuation of MOXY
based on a range of the estimated value of its assets and liabilities.  DLJ
determined a range of values for the Company's reserves based on information
contained in the preliminary reserve report of Ryder Scott dated June 17, 1997
applying a range of discount rates to the cash flows generated by such reserves
under various risk weightings of proved and probable reserves.  DLJ determined a
range of values for the Company's exploration acreage based on prices paid for
undeveloped acreage in recent lease sales and a discounted cash flow analysis
applying a range of discount rates and risk factors to the expected cash flow to
be generated from such prospects.  In order to perform this analysis, DLJ made
certain assumptions regarding the value of the Company's oil and gas reserves,
exploration acreage and other assets.  DLJ then subtracted from the value of the
Company's assets its outstanding liabilities including indebtedness.  Based on
this analysis, DLJ determined a high and low range of share prices for the
Company of  between $2.33 and $4.44 per share.

     Stock Trading History.   To provide contextual data and comparative market
data, DLJ examined the history of the trading prices for the Common Stock for
the latest twelve-month period ended June 27, 1997. DLJ also reviewed the daily
closing prices of the Common Stock and compared the closing stock prices with an
index consisting of comparable companies.  This information was presented solely
to provide the Board with background information regarding the stock prices of
the Company over the period indicated.  DLJ noted the high and low prices for
the Common Stock over the twelve-month period ended June 27, 1997 were $3.938
and $1.813, respectively.

     Pro Forma Analysis.  DLJ analyzed certain pro forma effects resulting from
the Transactions.  In conducting its analysis, DLJ relied upon certain
assumptions provided by management of the Company.  The analysis indicated that
the pro forma after-tax cash flow per share of the Company would be
approximately $0.16 per share, or 57%, higher on a pro forma basis in fiscal
year 1997 and $0.41 per share higher on a pro forma basis in fiscal year 1998,
than management estimates for the Company in the absence of the Transactions.
The results of the pro forma analysis are not necessarily indicative of future
operating results or financial performance.

     The summary set forth above does not purport to be a complete description
of the analyses performed by DLJ.  The preparation of a fairness opinion
involves various determinations as to the most appropriate and relevant methods
of financial analysis and the application of these methods to the particular
circumstances and, therefore, such an opinion is not readily susceptible to
summary description.  Each of the analyses conducted by DLJ was carried out in
order to provide a different perspective on the Transactions and add to the
total mix of information available.  DLJ did not form a conclusion as to whether
any individual analysis, 

                                       13
<PAGE>
 
considered in isolation, supported or failed to support an opinion as to
fairness. Rather, in reaching its conclusion, DLJ considered the results of the
analyses in light of each other and ultimately reached its opinion based on the
results of all analyses taken as a whole. DLJ did not place particular reliance
or weight on any individual analysis, but instead concluded that its analyses,
taken as a whole, supported its determination. Accordingly, notwithstanding the
separate factors summarized above, DLJ believes that its analyses must be
considered as a whole and that selecting portions of its analysis and the
factors considered by it, without considering all analyses and factors, could
create an incomplete or misleading view of the evaluation process underlying its
opinion. In performing its analysis, DLJ made numerous assumptions with respect
to industry performance, business and economic conditions and other matters. The
analyses performed by DLJ are not necessarily indicative of actual values or
future results, which may be significantly more or less favorable than suggested
by such analyses.

     Pursuant to the terms of an engagement letter dated April 9, 1997, the
Company has (i) paid to DLJ a retainer of $100,000 and a fee of $250,000 upon
delivery of the DLJ Opinion, and (ii) has agreed to pay to DLJ a fee of $150,000
upon closing of the Rights Offering.  The Company has also agreed to reimburse
DLJ promptly for all out-of-pocket expenses (including the reasonable fees and
out-of-pocket expenses of counsel) incurred by DLJ in connection with its
engagement, and to indemnify DLJ and certain related persons against certain
liabilities in connection with its engagement, including liabilities under the
federal securities laws.  The terms of the arrangement with DLJ, which DLJ and
the Company believe are customary in transactions of this nature, were
negotiated at arm's length between the Company and DLJ and the Board was aware
of such arrangement, including the fact that a significant portion of the
aggregate fee payable to DLJ is contingent upon consummation of the
Recapitalization Transactions.

     In the ordinary course of business, DLJ may actively trade the securities
of the Company and FRP for its own account and for the accounts of its customers
and, accordingly, may at any time hold a long or short position in such
securities.

THE RIGHTS OFFERING

     MOXY intends to use the net proceeds of the Rights Offering to purchase the
MCN Producing Properties, to repay the debt incurred under the MOXY/MCN Program,
to fund a portion of the Company's estimated capital requirements under the MOXY
FRP Exploration Program and for additional working capital and general corporate
purposes. It is anticipated that MOXY will issue approximately 28.6 million
shares of Common Stock for an aggregate of approximately $100 million of Common
Stock pursuant to the Rights Offering and the Standby Commitment.  If the
stockholders approve the Recapitalization Proposal, the Rights Offering will
commence as soon as possible after the Special Meeting.

     Pursuant to the Rights Offering, the Company will distribute at no cost to
each holder of Common Stock for each share owned as of the record date for the
Rights Offering a number of Rights equal to the quotient (estimated to be
approximately 2.0 Rights for each share of Common Stock) obtained by dividing
the number of shares outstanding on the Record Date by the number of shares to
be issued in the Rights Offering. Each Right will entitle the holder thereof to
purchase one share of Common Stock for the Subscription Price ($3.50 in cash).

     Commencement; Expiration; No Revocation. If the stockholders approve the
Recapitalization Proposal, the Rights Offering will commence promptly following
the Special Meeting and will expire at 5:00 p.m. on the Expiration Date, which
will be no less than 30 days after the Rights Offering commences.  The Company
may, with FRP's consent, extend the Expiration Date and will announce any
extension thereof by not later than 9:00 a.m., New York City time, on the
business day following the previously scheduled Expiration Date; provided that
the Expiration Date in no event shall be more than 30 days after the originally
established Expiration Date.  An extension of the Expiration Date will be for a
period of at least three Nasdaq trading days.  After the Expiration Date,
unexercised Rights will be null and void.  Once a holder of Rights has exercised
the Basic Subscription Privilege or the Oversubscription Privilege, such
exercise may not be revoked.

                                       14
<PAGE>
 
     Basic and Oversubscription Privileges.  Each Right will entitle the holder
thereof to receive, upon payment of the Subscription Price, one share of Common
Stock.  Each Right will also carry an Oversubscription Privilege right to
subscribe at the Subscription Price for additional shares of Common Stock not
subscribed for by other holders through the exercise of the Basic Subscription
Privilege.  Only holders who exercise the Basic Subscription Privilege in full
will be entitled to exercise the Oversubscription Privilege. If the Excess
Shares are insufficient to satisfy all subscriptions pursuant to the
Oversubscription Privilege, the Excess Shares will be allocated pro rata among
holders who exercise their Oversubscription Privilege in proportion to the
number of shares each holder subscribed for pursuant to the Basic Subscription
Privilege; provided, however, that no holder will be allocated more shares than
such holder subscribed for pursuant to the exercise of the Oversubscription
Privilege.

     Transferability.  The Rights will be transferable and it is expected that
they will trade on the Nasdaq National Market under the symbol "MOXYR" until the
close of business on the last Nasdaq National Market trading day prior to the
Expiration Date.

     Determination of the Subscription Price.  The Subscription Price was
determined by negotiations between MOXY and FRP.  The Board's objective in
establishing the Subscription Price was to approximate recent trading prices of
the Common Stock, raise the targeted proceeds and provide all of MOXY's
stockholders with a reasonable opportunity to make an additional investment in
the Company and avoid dilution of their ownership and voting percentage in the
Company, subject to the possible effects of the FRP Purchase Option.

     Certain Federal Income Tax Considerations.  For United States federal
income tax purposes, holders of Rights generally will not recognize taxable
income in connection with the issuance to them or exercise by them of Rights.
Rights holders may incur gain or loss upon the sale of the Rights or the shares
of the Common Stock acquired upon exercise of the Rights.

     THIS PROXY STATEMENT IS NOT AN OFFER TO SELL OR THE SOLICITATION OF AN
OFFER TO BUY SHARES OF COMMON STOCK OR ANY OTHER SECURITIES, INCLUDING THE
RIGHTS OR ANY SHARES OF COMMON STOCK ISSUABLE UPON EXERCISE OF THE RIGHTS.
OFFERS AND SALES OF THE COMMON STOCK ISSUABLE UPON EXERCISE OF THE RIGHTS WILL
ONLY BE MADE BY MEANS OF A PROSPECTUS MEETING THE REQUIREMENTS OF THE SECURITIES
ACT OF 1933, AS AMENDED, AND APPLICABLE STATE SECURITIES LAWS, ON THE TERMS AND
SUBJECT TO THE CONDITIONS SET FORTH IN SUCH PROSPECTUS, WHICH IS EXPECTED TO BE
DELIVERED TO STOCKHOLDERS IMMEDIATELY AFTER THE SPECIAL MEETING, PROVIDED THE
RECAPITALIZATION PROPOSAL IS APPROVED.

THE STANDBY PURCHASE AGREEMENT

     To ensure MOXY will obtain the funds sought through the Rights Offering,
MOXY and FRP have entered into the Standby Purchase Agreement, pursuant to
which, subject to certain limited exceptions, FRP has agreed to provide a
Standby Commitment to purchase at the Subscription Price a number of shares of
Common Stock equal to the number of shares of Common Stock not purchased
pursuant to the exercise of Rights.  Pursuant to the Standby Purchase Agreement,
FRP also has the option, exercisable if FRP does not acquire at least 30% of the
outstanding Common Stock pursuant to the Standby Commitment, to purchase at the
Subscription Price such additional shares of Common Stock as are necessary to
provide it with up to a 30% ownership interest in MOXY after giving effect to
the completion of the Rights Offering and the purchase of shares pursuant to the
Standby Commitment and the FRP Purchase Option.  The FRP Purchase Option must be
exercised and closed simultaneously with the closing of the Standby Commitment.
MOXY has agreed to pay a standby fee (the "Standby Fee") of $6 million to FRP,
payable upon the closing of the Rights Offering, for providing the Standby
Commitment, acquiring the MCN Producing Properties for resale to MOXY and
entering the MOXY/MCN Exploration Program.  MOXY will not be obligated to pay
the Standby Fee unless the Standby Purchase Agreement and the transactions
contemplated thereby are approved at the Special Meeting.

     The rights and obligations of MOXY and FRP under the Standby Purchase
Agreement are subject to certain customary conditions, including the absence of
any pending or threatened action, suit or proceeding relating to the Rights
Offering or the Standby Purchase Agreement.

     If less than approximately 25% of the Rights are exercised by holders, then
FRP will acquire a majority of MOXY's outstanding Common Stock pursuant to the
Standby Commitment.  If FRP exercises the FRP Purchase Option in full, FRP will
own 30% of MOXY's outstanding Common Stock.  See "- Potential Effects of the
Recapitalization Transactions on Control of MOXY."

     The foregoing summary of the Standby Purchase Agreement is qualified in its
entirety by reference to the complete text thereof, which is attached hereto as
Annex II.

STOCKHOLDER AGREEMENT; REGISTRATION RIGHTS

     MOXY and FRP have agreed to enter into the Stockholder Agreement that
provides for (i) the implementation of certain corporate governance measures
designed to protect the stockholders of MOXY other than FRP, (ii) the ability of
FRP to elect a certain number of directors if it owns more than 10% but less
than a majority of the outstanding Common Stock and (iii) certain registration
rights with respect to the shares of Common Stock that FRP may acquire pursuant
to the Standby Commitment and the FRP Purchase Option.

     Pursuant to the Stockholder Agreement, as long as FRP owns at least 10% but
less than a majority of the outstanding Common Stock of MOXY, FRP will be
entitled to nominate that number of directors equal to the nearest whole number
obtained by multiplying FRP's percentage interest in the outstanding Common
Stock by the number of directors that are to serve on the Board of Directors.
MOXY has agreed to create such number of vacancies on the Board of Directors
either by (i) an increase in the Board of Directors in accordance with the terms
of MOXY's Certificate of Incorporation and By-Laws, (ii) director resignations
or (iii) a combination thereof.

     In connection with each meeting of stockholders of MOXY at which the term
of any of FRP's designees expires, the Board of Directors will nominate for
election as a director of MOXY the designee of FRP to stand for election for a
succeeding term and will vote all management proxies in favor of such designee,
except for such proxies that specifically indicate to the contrary.  FRP will
have the right to designate replacements for directors designated by FRP
pursuant to this Agreement, if such director declines or is unable to serve for
any reason, at the end of such director's term, or upon such director's
resignation or removal.

     FRP has informed MOXY that at the present time it does not intend to use
this provision to make any changes to the current composition of the Board,
subject to the appointment of Independent Directors as discussed below.

     MOXY has also agreed to take such actions on or before January 14, 1998, as
are necessary to create at least two vacancies on the Board of Directors either
by (i) an increase in the number of directors in accordance with the Certificate
of Incorporation or By-Laws; (ii) director resignations or (iii) a combination
thereof.  MOXY has agreed to designate and elect at least two directors each of
whom (a) would qualify as an independent director within the meaning given to
such term under the rules of the New York Stock Exchange and (b) is not an
"Affiliate" or "Associate" (as each such term is defined in Rule 405 under the
Securities Act of 1933, as amended (the "Securities Act")) of FRP, other than
solely as a result of being a director of MOXY (each an "Independent Director").
MOXY has agreed to maintain at all times a committee of the Board of Directors
comprised of all such Independent Directors (the "Independent Committee").

     Until the date on which FRP ceases to own at least 10% of the outstanding
Common Stock, MOXY has agreed not to take any of the following actions without
the approval of the Independent Committee: (a) repurchase any outstanding shares
of Common Stock; (b) enter into (i) any sale, lease, transfer or other
disposition by MOXY of any of its properties or assets to, (ii) any purchase of
property or assets by MOXY from, (iii) any investment by MOXY in, (iv) any
agreement by MOXY with or for the benefit of, or (v) any other 

                                       16
<PAGE>
 
transaction with one or more of its affiliates that involves aggregate payments
in excess of $5 million; (c) enter into any "Rule 13e-3 transaction" within the
meaning of Rule 13e-3 under the Securities Exchange Act of 1934, as amended (the
"Exchange Act"), (d) amend, modify or grant any waiver under the Rights Plan,
the Participation Agreement or the Stockholder Agreement or (e) in connection
with any merger or business combination involving MOXY and a third party, treat
FRP and the other holders of Common Stock on other than equivalent terms.

     Until the date on which FRP ceases to own, directly or indirectly, at least
10% of the outstanding Common Stock of MOXY, FRP will not, without the approval
of the Independent Committee, purchase, acquire, agree to acquire or offer to
acquire beneficial ownership of any additional shares of Common Stock (other
than through open-market purchases that do not constitute "Rule 13e-3
transactions" within the meaning of Rule 13e-3 under the Exchange Act), or enter
into, propose to enter into, solicit or support any merger or business
combination or similar transaction involving FRP or any of its affiliates and
MOXY.

     Pursuant to the Stockholder Agreement, FRP will be  entitled to demand
registration rights with respect to any shares of Common Stock that it owns;
provided that FRP register no less than  10% of the outstanding Common Stock
pursuant to each such registration and that MOXY not be required to effect more
than one such registration in any 12-month period nor more than three such
registrations in the aggregate. In addition, if the Company proposes to register
any Common Stock under the Securities Act in connection with a public offering,
FRP may require MOXY to include all or a portion of the shares owned by FRP at
that time.  MOXY has agreed to pay all the expenses of any registration under
the Stockholder Agreement, other than underwriters' discounts and commissions,
and to indemnify FRP for certain liabilities in connection with any such
registration.

     The foregoing summary of the Stockholder Agreement is qualified in its
entirety by reference to the complete text thereof, which is attached hereto as
Annex III.

PURCHASE OF MCN PRODUCING PROPERTIES

     In July 1997, FRP agreed to acquire from MCN its interests in the MOXY/MCN
Program, the MCN Producing Properties and other exploratory properties acquired
under the MOXY/MCN Program for $31.0 million, as adjusted for the net revenues
and development and operating costs of such properties from April 1, 1997 until
their acquisition by FRP, and an additional amount equal to the amount loaned by
MCN to MOXY under the MOXY/MCN Program.  On __________, 1997, FRP paid MCN,
after adjustments, $_______ for such assets together with $_______ for the
outstanding indebtedness.

     MOXY and FRP have amended the MOXY/MCN Program to extend the program term,
include their interests in the seven offshore leases acquired by MOXY and FRP at
the Central Gulf of Mexico lease sale held in March 1997, and provide for the
conduct of mutually agreed exploration projects until the earlier of December
31, 1997 or, if the Recapitalization Proposal is approved at the Special
Meeting, until the date of the completion of the Rights Offering.  The amendment
also provided that FRP will reimburse MOXY for approximately $290,000 of
overhead costs per month and will continue to advance funds to MOXY under the
MOXY/MCN Program during the remaining program term.

     Upon completion of the Rights Offering, MOXY will acquire the MCN Producing
Properties from FRP for $26.0 million, subject to the adjustments described
above with respect to revenues and costs attributable to the MCN Producing
Properties from April 1, 1997 until their acquisition by MOXY plus interest,
calculated on the daily outstanding balance of $26.0 million purchase price, as
adjusted, from ___________, 1997 until MOXY's acquisition of the properties at
an annual rate publicly announced by The Chase Manhattan Bank from time to time
plus 2%.  At the same time, MOXY will repay to FRP all amounts advanced to MOXY
under the MOXY/MCN Program.  Thereafter, MOXY will retain a 100% interest in the
MCN Producing Properties and MOXY and FRP will dedicate to the MOXY/FRP
Exploration Program all other oil and gas properties then subject to the
MOXY/MCN Program.

THE MOXY/FRP EXPLORATION PROGRAM

     Pursuant to the Master Agreement and subject to the terms and conditions
contained therein, including the closing of the MCN Purchase and completion of
the Rights Offering, MOXY and FRP have agreed to establish the MOXY/FRP
Exploration Program. MOXY will manage the MOXY/FRP Exploration Program,
selecting all prospects and drilling opportunities, and will serve as operator
of all wells drilled by the MOXY/FRP Exploration Program.  MOXY and FRP will
commit $200 million for exploration expenses to be incurred under the MOXY/FRP
Exploration Program, with exploration costs being shared 40% by MOXY and 60% by
FRP.  Exploration costs consist of all costs associated with leasehold
acquisition and maintenance, geological and geophysical studies, seismic
surveys, drilling exploratory wells, overhead reimbursements, and all other
aspects of identifying prospects and drilling exploratory wells.  All revenues
and all costs other than exploration costs will be shared equally by MOXY and
FRP.

     MOXY and FRP will receive credits against the $200 million program
commitment for an aggregate of $8.3 million for certain exploratory costs
incurred under the MOXY/MCN Program prior to the establishment of the MOXY/MCN
Exploration Program.  All exploratory prospects in the MOXY/MCN Program will be
transferred to the MOXY/FRP Exploration Program and MOXY will acquire an
additional interest in each such property to reflect the sharing of revenues and
costs under the MOXY/FRP Exploration Program.  The MOXY/FRP Exploration Program
will terminate after initial exploration program expenditures of $200 million
have been committed or June 30, 2002, whichever is earlier.

     Any amendment to the  agreements constituting the MOXY/FRP Exploration
Program or other waiver of MOXY's rights thereunder will be required to be made
by the Independent Committee.  See "- Stockholder Agreement; Registration
Rights."

     The foregoing summary of the MOXY/FRP Exploration Program is qualified in
its entirety by reference to the complete text of the Participation Agreement
between MOXY and FRP, which is attached hereto as Annex IV.

POTENTIAL EFFECTS OF THE RECAPITALIZATION TRANSACTIONS ON CONTROL OF MOXY

     Pursuant to, and subject to the terms and conditions of,  the Standby
Purchase Agreement, FRP has agreed to purchase from MOXY all shares of Common
Stock that are offered but not purchased pursuant to the exercise of the Rights.
Accordingly, if less than approximately 25% of the Rights are exercised by the
holders, then FRP will acquire pursuant to the Standby Commitment a majority of
the outstanding Common Stock and will have the power to control MOXY's business
and affairs.  If, as a result of the Standby Commitment or the FRP Purchase
Option, FRP acquires or holds more than 10% but less than a majority of the
outstanding Common Stock, pursuant to the Stockholder Agreement, it will be
entitled to designate a number of directors proportionate to its stock ownership
in MOXY and may have the power to significantly influence the Company's business
and affairs.

     MOXY's Certificate of Incorporation does not provide for cumulative voting
in the election of directors. As a holder of a majority of the Common Stock, FRP
would have the ability to elect all of the directors on MOXY's Board.  The Board
is empowered by the Delaware General  Corporation Law ("DGCL") to direct the
management of the business of MOXY and to make numerous major decisions without
stockholder approval. Matters and decisions subject to Board control include,
among other things, the purchase and sale of assets of MOXY (other than a
disposition of all or substantially all of MOXY's assets outside of the ordinary
course of business), the issuance of additional equity or debt securities
(subject to limitations imposed by the Certificate of Incorporation and debt
agreements), the declaration of dividends in respect of MOXY's capital stock,
the election and removal of officers of MOXY, capital expenditure decisions,
strategic planning, by-law amendments, officer compensation matters, and the
recommendation for stockholder approval of certain major corporate transactions
(including mergers, certain asset sales, charter amendments and dissolutions).

     If FRP acquires a majority of the outstanding Common Stock, FRP will hold
a majority of the voting power and have the right to elect all of the directors
of the Board.  Under the DGCL and the Certificate of 

                                       18
<PAGE>
 
Incorporation and By-laws, the following matters generally require the approval
of the holders of a majority of the outstanding shares entitled to vote (subject
to any additional rights of the holders of any class or series of stock to vote
on such matters separately as a class): (i) a merger of MOXY with or into
another corporation or other entity; (ii) a sale, lease, exchange or disposition
of all or substantially all of MOXY's assets other than in the ordinary course
of business; (iii) the amendment of the Certificate of Incorporation, subject to
certain exceptions; and (iv) a dissolution of MOXY. In addition, the Independent
Committee will be required to approve certain transactions. See "-Stockholder
Agreement; Registration Rights." Subject to certain exceptions, the Nasdaq rules
also require that the following securities issuances by listed companies be
approved by at least a majority of the votes cast at a properly constituted
meeting of Stockholders: (a) the establishment of a stock option or purchase
plan or arrangement pursuant to which stock may be acquired by officers and
directors, except for warrants or rights issued generally to security holders or
broadly-based plans or arrangements including other employees; (b) the issuance
of common stock in exchange for the acquisition, directly or indirectly, of
stock or assets from a director, officer or substantial security holder of the
company who holds a 5% or greater interest in the assets or company to be
acquired; (c) the issuance of common stock or securities convertible into or
exchangeable for common stock representing more than 20% of the common stock or
voting power outstanding prior to the issuance, other than in a public offering
for cash; and (d) an issuance of securities that will result in a change of
control of the company.

     Assuming that FRP will hold more than a majority of the Common Stock, the
directors elected by FRP, if they vote together, would have the ability to
control the outcome of all votes taken by the Board, subject to the approval of
the Independent Committee in certain limited instances.  Under applicable law,
such directors, like all directors, will have fiduciary obligations to all of
MOXY's stockholders, not just to FRP. However, FRP's right to control the Board
could have the effect of delaying, deterring or preventing tender offers or
takeover attempts that some or a majority of MOXY's stockholders might consider
to be in their best interests, including offers or attempts that might result in
the payment of a premium over the market price for the Common Stock.

     In addition, the Recapitalization Transactions will be exempt from the
application of certain anti-takeover provisions, including Section 203 of the
DGCL, the fair price provision contained in the Certificate and the Company's
Rights Plan.

     Section 203 of the DGCL prevents an "interested stockholder" (defined as a
stockholder owning 15 percent or more of a corporation's voting Stock) from
engaging in a business combination with such corporation for a period of three
years from the date such stockholder became an interested stockholder unless (a)
the corporation's board of directors had earlier approved either the business
combination or the transaction by which the stockholder became an interested
stockholder,  (b) upon attaining that status, the interested stockholder had
acquired at least 85 percent of the corporation's voting stock (not counting
shares owned by persons who are directors and also officers of such corporation)
or (c) the business combination is later approved by the board of directors and
authorized by a vote of two-thirds of the stockholders (not including the shares
held by the interested stockholder).  The Board of Directors has approved the
Recapitalization Transactions and, therefore, FRP will not be considered an
"interested stockholder" as defined by Section 203 of the DGCL as a result of
the Recapitalization Transactions.

     Article Ninth of MOXY's Certificate of Incorporation provides that certain
fundamental transactions between MOXY and a 20% stockholder require approval of
the holders of shares having 85% of the total voting power, unless (i) certain
"fair price" provisions are satisfied, (ii) the transaction involves a wholly-
owned subsidiary of the Company, or (iii) the transaction is approved by a
majority of the "Continuing Directors," which would exclude directors affiliated
with or nominated by the 20% stockholder.  FRP and FTX are specifically excluded
from the application of this provision.

     Pursuant to the Company's Rights Plan, any person other than Oppenheimer
Group, Inc., who becomes the beneficial owner of 15% or more of the outstanding
Common Stock of the Company shall be deemed an "Acquiring Person."  If a person
becomes an Acquiring Person, each holder of a right under the Rights Plan will
thereafter have the right to receive upon exercise thereof at the then current
purchase price, Common Stock having a market value equal to two times the
purchase price.  Prior to entering into the Standby Purchase Agreement, MOXY
amended the Rights Plan to exclude FRP from the Rights Plan.  See 

                                       19
<PAGE>
 
"Description of Capital Stock - Certain Provisions of the Company's Certificate
and By-laws and Delaware Law -- Stockholder Approval of Combinations; Fair Price
Provisions" and "-- Preferred Stock Purchase Rights."

     MOXY and FRP have agreed to adhere to the policies set forth in the
Stockholder Agreement at any time FRP owns more than 10% of the outstanding
Common Stock.  In accordance with the Stockholder Agreement, no later than
January 14, 1998, MOXY will be required to elect and maintain an Independent
Committee of the Board of Directors consisting of at least two independent
directors appointed to MOXY's Board.    See "--Stockholder Agreement;
Registration Rights."

     Until the date on which FRP ceases to own at least 10% of the outstanding
Common Stock, MOXY will not take any of the following actions without the
approval of the Independent Committee:  (a) repurchase any outstanding shares of
Common Stock; (b) enter into (i) any sale, lease, transfer or other disposition
by MOXY of any of its properties or assets to, (ii) any purchase of property or
assets by MOXY from, (iii) any investment by MOXY in, (iv) any agreement by MOXY
with or for the benefit of, or (v) any other transaction with one or more of its
affiliates that involves aggregate payments in excess of $5 million; (c) enter
into any "Rule 13e-3 transaction," within the meaning of Rule 13e-3 under the
Exchange Act; (d) amend, modify or grant any waiver under the Rights Plan, the
Participation Agreement or the Stockholder Agreement, or (e) in connection with
any merger or business combination involving MOXY and a third party, treat FRP
and the other holders of Common Stock on other than equivalent terms.

     In addition, until the date on which FRP ceases to own, directly or
indirectly, at least 10% of the outstanding voting stock of MOXY, FRP will not,
without the approval of the Independent Committee, purchase, acquire, agree to
acquire or offer to acquire beneficial ownership of any additional shares of
Common Stock (other than through open-market purchases that do not constitute
"Rule 13e-3 transactions" within the meaning of Rule 13e-3 under the Exchange
Act), or enter into, propose to enter into, solicit or support any merger or
business combination or similar transaction involving FRP or any of its
affiliates and MOXY.

INTERESTS OF CERTAIN PERSONS IN THE RECAPITALIZATION TRANSACTIONS

     FTX currently owns a 51.6% interest in, and is the administrative managing
general partner of, FRP. All of the directors who serve on the Company's Board
of Directors also serve on the Board of Directors of FTX.  In addition, James R.
Moffett, who serves as Co-Chairman of the Board of the Company also serves as
Chairman of the Board of FTX.  Furthermore, Richard C. Adkerson, who serves as
Co-Chairman of the Board and Chief Executive Officer of the Company also serves
as Vice Chairman of the Board of FTX.  Both Dean T. Falgoust and Craig E.
Saporito serve as Vice Presidents of both the Company and FTX, Michael C.
Kilanowski, Jr. serves as Secretary of both the Company and FTX, and William J.
Blackwell serves as Controller for the Company and FTX.

USES OF FUNDS

     The net proceeds received by the Company from the sale of the shares of
Common Stock pursuant to the Rights Offering and the Standby Commitment are
estimated to be approximately $93 million, after payment of fees and expenses,
including the Standby Fee. The net proceeds, together with any proceeds from the
exercise of the FRP Purchase Option, will be used to purchase the MCN Producing
Properties, repay the indebtedness incurred by MOXY under the MOXY/MCN Program
(which bears interest at the annual base rate announced from time to time by The
Chase Manhattan Bank plus 2%), to fund a portion of MOXY's estimated capital
requirements under the MOXY/FRP Exploration Program and for additional working
capital and general corporate purposes.

ADVANTAGES AND DISADVANTAGES OF THE RECAPITALIZATION TRANSACTIONS

     The principal advantages that the Board believes will result from the
Recapitalization Transactions are (i) a substantial improvement in MOXY's
capital structure and an increase in its liquidity through the substantial
increase in its invested equity capital, (ii) the ability to continue and
substantially expand MOXY's 

                                       20
<PAGE>
 
exploration program and manage drilling risk through participation in an
increased number of drilling prospects, (iii) the increase in proved reserves
and cash flow from the MCN Producing Properties in which MOXY currently has an
interest, (iv) the ability of MOXY's current stockholders who wish to do so to
maintain or increase their proportionate equity and voting interest in the
Company, subject to the possible effects of the FRP Purchase Option, by
exercising their Rights to purchase additional shares of Common Stock pursuant
to the Basic Subscription Privilege and the Oversubscription Privilege, (v) the
ability of stockholders who do not wish to purchase additional shares of Common
Stock to transfer and thereby receive the market value of the Rights and (vi)
the ability of MOXY's current stockholders to participate in any long-term
benefits received in connection with MOXY's existing exploration activities and
the MOXY/FRP Exploration Program.

     The principal disadvantage of the Recapitalization Transactions considered
by the Board was the potential dilution of the equity interests of existing
stockholders who do not choose to exercise their Rights. The Board also
considered (i) the potential dilutive effect of the FRP Purchase Option to
current stockholders and (ii) the potential transfer of control of MOXY to FRP
as a result of the Recapitalization Transactions.  While the sale of equity
securities is dilutive, the ability of MOXY's existing stockholders to
participate in the Recapitalization Transactions via the purchase of Common
Stock at the same price as that being paid by FRP mitigates such dilution.
Stockholders who do not wish to make the additional economic investment required
for such purchase may mitigate such dilution by selling their Rights in the
market.

CONSEQUENCES IF THE RECAPITALIZATION PROPOSAL IS NOT APPROVED

     If the stockholders do not approve the Recapitalization Proposal, the
Recapitalization Transactions will not be completed, FRP will retain its
interest in the MOXY/MCN Program, the MOXY/FRP Exploration Program will not be
established and the expanded exploration activities contemplated thereby will
not be undertaken.  FRP will have the obligation to fund, and extend credit to
MOXY to fund, any exploration and development costs that may be committed under
the amended MOXY/MCN Program and any other amounts that may be borrowed by MOXY
thereunder with respect to the properties then subject to the MOXY/MCN Program.
FRP will not be obligated to fund any other exploratory prospects.

     As a result, MOXY will be forced to secure alternative sources of financing
to support its current operations beyond the financing available under the
MOXY/MCN Program and fund any future exploration and development activities.
All of the net revenues generated from MOXY's producing oil and gas properties
are dedicated to repay indebtedness incurred under the MOXY/MCN Program.  Such
alternative sources could include additional equity or debt financing, the sale
of all or part of MOXY's assets or other partnership or joint venture
transactions.  There can be no assurance that alternative financing will be
available on acceptable terms, if at all, or that the Company will be a viable
business enterprise.  See "The Recapitalization Transactions - Consequences if
the Recapitalization Proposal is Not Approved."

     The Company's business strategy is to create value for its stockholders
through the discovery of oil and gas reserves in its exploration and development
activities.  If the Recapitalization Transactions are not approved at the
Special Meeting, MOXY will be forced to seek alternatives to the MOXY/FRP
Exploration Program.  Rejection of the Recapitalization Transactions will not
prohibit the Company from entering into other exploration programs or  joint
ventures, including those with FRP or any other party, and with any financial
commitment that the Company deems appropriate.

ABSENCE OF APPRAISAL RIGHTS

     Under Delaware law and MOXY's Certificate of Incorporation, objecting
stockholders will have no appraisal, dissenters' or similar rights (i.e., the
right to seek a judicial determination of the "fair value" of the Common Stock
and to compel MOXY to purchase their shares of Common Stock for cash in that
amount) with respect to the matter presented at the Special Meeting or otherwise
with respect to the Recapitalization Transactions, nor will such rights be
voluntarily accorded to stockholders by MOXY. Therefore, if the matter submitted
for the approval of the stockholders at the Special Meeting is approved by the
requisite number of shares, such approval will bind all stockholders and
objecting stockholders will have no alternative other than selling their Common
Stock in the market.

EXPENSES OF THE RECAPITALIZATION TRANSACTIONS

     MOXY expects to incur expenses incident to the Recapitalization
Transactions of approximately $7.0 million, including the $6.0 million Standby
Fee payable to FRP.

                     PROPOSAL TO APPROVE AMENDMENTS TO THE
               1994 STOCK OPTION PLAN FOR NON-EMPLOYEE DIRECTORS

     MOXY seeks stockholder approval of amendments ("Director Plan Amendments")
to the MOXY 1994 Stock Option Plan for Non-Employee Directors (the ''Director
Plan'').  The Director Plan and the Director Plan Amendments are summarized
below.  The summary is qualified in its entirety by reference to the text of the
Director Plan, as it is proposed to be amended, which is attached hereto as
Annex VI.

REASONS FOR THE PROPOSED CHANGES

     In order to provide MOXY's non-employee directors with an appropriate level
of long-term incentive consistent with the increased size of MOXY that would
result upon completion of the Recapitalization Transactions, the Board proposes
the Director Plan Amendments to (i) increase the number of shares subject to the
automatic option granted each year, (ii) provide for a grant of options on July
14, 1997, and (iii) increase the number of shares subject to the Director Plan.
The Director Plan Amendments are subject to stockholder approval as well as
stockholder approval of the Recapitalization Proposal.

     The Director Plan currently provides an automatic grant to each non-
employee director of an option to purchase 1,656 shares of Common Stock; the
Director Plan Amendments provide that commencing on June 1, 1998 the automatic
grant will be an option to purchase 4,968 shares of Common Stock, which will be
consistent with the increased size of MOXY's that would result upon completion
of the Recapitalization Transactions.  In order to provide additional shares
subject to options currently held by directors, the amendment also provides for
a grant on July 14, 1997 of an option to purchase 13,248 shares of Common Stock.
Additionally, in order for a sufficient number of shares to be available under
the Director Plan for future option grants, the Director Plan Amendments also
increase the total number of shares in respect of which options may be granted
from 250,000 to 410,000.

SUMMARY OF THE DIRECTOR PLAN AS PROPOSED TO BE AMENDED

     The purpose of the Director Plan is to align more closely the interests of
MOXY's non-employee directors with those of MOXY's stockholders by providing for
the automatic grant of stock options to such directors in accordance with the
terms of the Director Plan.

     The maximum number of shares of Common Stock in respect of which options
may be granted under the Director Plan is 410,000.  On July 14, 1997, the
closing sale price of a share of Common Stock as reported on the Nasdaq National
Market was $3 5/8.   The shares of Common Stock to be delivered under the
Director Plan will be made available from the authorized but unissued shares of
Common Stock or from treasury shares.

     Except for determinations with respect to the transferability of options,
which are made by the Corporate Personnel Committee (the "Committee") of the
Board, the Director Plan is administered by the Board; however, the Board has no
discretion to determine the timing, exercise price or amount of options granted
under the Director Plan.

     All directors of the Company who are not, and within the preceding one year
have not been, employees or officers of MOXY or any of its affiliated companies
or officers or employees of an entity with which MOXY has contracted to receive
management services are ''Eligible Directors'' under the Director Plan. There
are presently eight Eligible Directors.  Under the Director Plan each Eligible
Director was granted on July 14, 1997 an option to purchase 13,248 shares of
Common Stock, subject to stockholder approval of the Director Plan Amendments
and the Recapitalization Proposal at the Special Meeting, and, on June 1, 1998,

                                       22
<PAGE>
 
and on June 1 of each subsequent year through and including 2003, each Eligible
Director will be granted an option to purchase 4,968 shares of Common Stock.

     Options granted under the Director Plan are non-qualified options.  The
exercise price of options granted under the Director Plan will be 100% of the
fair market value of the underlying shares of Common Stock on the date of grant.
Each option becomes exercisable in 25% annual increments beginning on the first
anniversary of the date of grant, and will have a term of 10 years.  An option
may be exercised generally only during a ten-day trading period following the
public release by MOXY of its quarterly or annual financial statements.  Upon
retirement from service as a director, a retiring director's options that were
exercisable on the date of retirement or could have become exercisable within
one year after such date will remain exercisable until the earlier of (i) the
third anniversary of the date of such retirement or (ii) the expiration date of
the option.  Options become exercisable in full upon a change of control of
MOXY, as defined in the Director Plan.

     The option exercise price may be paid in cash or by delivering shares of
Common Stock owned by the optionee or by a combination of cash and Common Stock.
The ability to pay the option exercise price in Common Stock would permit an
optionee to engage in a series of successive stock-for-stock exercises of an
option (sometimes referred to as "pyramiding") and thereby fully exercise an
option with little or no cash investment; however, it is the Committee's policy
to require any stock tendered in payment of the exercise price to be in
certificated form.

     In the event of the payment of any dividend payable in shares of Common
Stock, or any subdivision or combination of such shares of Common Stock, the
number of shares that may be purchased under the Director Plan and the number of
shares subject to each option granted under the Director Plan will be increased
or decreased proportionately, as the case may be, and the number of shares
deliverable upon the exercise thereafter of any outstanding option (whether or
not then exercisable) will be increased or decreased proportionately, as the
case may be, without change in the aggregate exercise price.  In the event MOXY
is merged or consolidated into or with another corporation in a transaction in
which MOXY is not the survivor, or in the event that substantially all of MOXY's
assets are sold to another entity not affiliated with MOXY, any holder of an
option, whether or not then exercisable, will be entitled to receive (unless
MOXY takes such alternative action as may be necessary to preserve the economic
benefit of the option for the optionee) on the effective date of any such
transaction, in cancellation of such option, an amount in cash equal to the
excess, if any, of the fair market value on the effective date of any such
transaction of the shares underlying such option over the aggregate exercise
price thereof.

     No option may be transferred, pledged, assigned, or otherwise encumbered by
the holder thereof except by will or by the laws of descent and distribution or,
if permitted by the Committee, pursuant to a domestic relations order, to
immediate family members, or to entities controlled by or for the benefit of,
either exclusively or predominately, immediate family members.

     The Director Plan may be amended or terminated at any time by the Board of
Directors, except that no amendment may be made without stockholder approval if
such amendment would (i) increase the maximum number of shares of Common Stock
that may be purchased pursuant to options granted either individually or on an
annual basis in the aggregate, (ii) permit the granting of any option with an
exercise price other than 100% of the fair market value of the underlying shares
of Common Stock on the date of grant, (iii) permit the exercise of an option
unless the full purchase price of the shares as to which the option is exercised
is paid at the time of exercise, (iv) extend beyond June 1, 2003 the period
during which options may be granted, (v) modify in any respect the class of
individuals who constitute Eligible Directors, or (vi) materially increase the
benefits accruing to participants thereunder.

     When an optionee exercises an option, the difference between the option
price and any higher fair market value of the shares of Common Stock, generally
on the date of exercise, will be ordinary income to the optionee and generally
will be allowed as a deduction for federal income tax purposes to MOXY.

                                       23
<PAGE>
 
     Any gain or loss realized by an optionee on disposition of the Common Stock
acquired upon exercise of an option generally will be capital gain or loss to
such optionee, long-term or short-term depending on the holding period, and will
not result in any additional tax consequences to MOXY.  The optionee's basis in
the shares of Common Stock for determining gain or loss on the disposition will
be the fair market value of such shares of Common Stock determined generally at
the time of exercise.

     Except as noted below, when an optionee receives payment with respect to an
option under the Director Plan other than as described in the preceding
paragraphs, the amount of cash and the fair market value of the securities
received, net of any amount paid by the optionee, will be ordinary income to
such optionee and generally will be allowed as a deduction for federal income
tax purposes to MOXY.  If the exercise price of an option is paid by the
surrender of previously owned shares, the basis of the previously owned shares
carries over to the shares received in replacement therefor.  The income
recognized on exercise is added to the basis.

     The following table sets forth information with respect to the benefits
under the Director Plan, as proposed to be amended, that were received on July
14, 1997, subject to stockholder approval of the Director Plan Amendments and
the Recapitalization Proposal, by (i) each of the directors who is not an
executive officer and (ii) all directors who are not executive officers as a
group.

          PROPOSAL TO APPROVE AMENDMENTS TO THE 1994 STOCK OPTION PLAN

     MOXY seeks stockholder approval of amendments ("Stock Plan Amendments") to
the MOXY 1994 Stock Option Plan (the "Stock Plan").  The Stock Plan and the
Stock Plan Amendments are summarized below.  The summary is qualified in its
entirety by reference to the text of the Stock Plan, as it is proposed to be
amended, which is attached hereto as Annex VII.

REASONS FOR THE PROPOSED CHANGES

     In order to provide MOXY's officers, employees and certain other persons
providing services to MOXY with an appropriate level of long-term incentive
consistent with the increased size of MOXY that would result upon completion of
the Recapitalization Transactions, on July 14, 1997, the Committee granted to
such persons options to purchase an aggregate of 1,954,000 shares of Common
Stock.  These grants are subject to stockholder approval of the Stock Plan
Amendments, which the Board approved, and stockholder approval of the
Recapitalization Proposal.  The Stock Plan Amendments increase the number of
shares authorized under the Stock Plan from 1,000,000 to 3,000,000 and increase
the maximum number of shares subject to grants an individual may receive in one
year from 200,000 to 600,000.

SUMMARY OF THE STOCK PLAN AS PROPOSED TO BE AMENDED

Administration

     Awards under the Stock Plan are made by the Committee, which currently
consists of five members of the Board, each of whom is a "non-employee director"
within the meaning of Rule 16b-3 under the Securities Exchange Act of 1934 (the
"Exchange Act") and qualifies as an "outside director" under Section 162(m) of
the Internal Revenue Code of 1986 (the "Code").  The Committee has full power
and authority to designate participants, set the terms of awards and to make any
determinations necessary or desirable for the administration of the Stock Plan.

Eligible Participants

     Officers and key employees of MOXY and its existing or future subsidiaries
and officers and employees of any entity with which MOXY has contracted to
receive management services and who provide services to MOXY under such
arrangement are eligible to participate in the Stock Plan.  The Committee may
delegate to certain officers of MOXY the power to make awards to eligible
persons who are not officers or directors of MOXY for purposes of Section 16 of
the Exchange Act, subject to limitations to be established by the Committee.  It
is estimated that approximately 275 persons are eligible for awards under the
Stock Plan; however, only 24 persons presently hold outstanding awards under the
Stock Plan.

Number of Shares

     The maximum number of shares of Common Stock with respect to which awards
payable in shares of Common Stock may be granted under the Stock Plan is
3,000,000.  No individual may receive in any year awards under the Stock Plan
that relate to more than 600,000 shares of Common Stock.  Shares subject to
awards that are forfeited or canceled will again be available for award.  The
shares to be delivered under the Stock Plan will be made available from the
authorized but unissued shares of Common Stock or from treasury shares.

     On July 14, 1997, the closing price of a share of Common Stock on the
Nasdaq National Market was $3 5/8.

                                       25

Types of Awards

     Stock options, stock appreciation rights, limited rights and other stock-
based awards may be granted under the Stock Plan in the discretion of the
Committee.  Options granted under the Stock Plan may be either non-qualified or
incentive stock options.  Only officers and employees of MOXY or its
subsidiaries or officers or employees of entities with which MOXY has contracted
to receive management services who provide services to MOXY or its subsidiaries
through such arrangement will be eligible to receive incentive stock options.
Stock appreciation rights and limited rights may be granted in conjunction with
or unrelated to other awards and, if in conjunction with an outstanding option
or other award, may be granted at the time of such award or thereafter, at the
exercise price of such other award.  The Committee has discretion to fix the
exercise price of such options, stock appreciation rights and limited rights at
a price not less than 100% of the fair market value of the underlying Common
Stock at the time of grant thereof (or at the time of grant of the related award
in the case of a stock appreciation right or limited right granted in
conjunction with an outstanding award), except that this limitation on the
Committee's discretion does not apply in the case of awards granted in
substitution for outstanding awards previously granted by an acquired company or
a company with which MOXY combines.  The Committee has broad discretion as to
the terms and conditions upon which options and stock appreciation rights are
exercisable, but under no circumstances will an option, a stock appreciation
right or a limited right have a term exceeding 10 years.

     No award may be transferred, pledged, assigned, or otherwise encumbered by
the holder thereof except by will; by the laws of descent and distribution; if
permitted by the Committee, pursuant to a domestic relations order; or, if
permitted by the Committee, stock options and limited rights granted in
conjunction therewith may be transferred or assigned to immediate family
members, or to entities controlled by or for the benefit of, either exclusively
or predominately, immediate family members.

     The option exercise price may be paid in cash, or in the discretion of the
Committee, by exchanging Common Stock owned by the optionee or by a combination
of cash and Common Stock.  The ability to pay the option exercise price in
Common Stock would permit an optionee to engage in a series of successive stock-
for-stock exercises of an option (sometimes referred to as "pyramiding") and
thereby fully exercise an option with little or no cash investment; however, it
is the Committee's policy to require any stock tendered in payment of the
exercise price to be in certificated form.

     Upon the exercise of a stock appreciation right with respect to Common
Stock, a participant would be entitled to receive, for each such share subject
to the right, the excess of the fair market value of such shares on the date of
exercise over the exercise price of such right.  The Committee has the authority
to determine whether the value of a stock appreciation right is paid in cash or
Common Stock or a combination thereof.

     Limited rights generally are exercisable only during a period beginning not
earlier than one day and ending not later than 90 days after the expiration date
of any tender offer, exchange offer or similar transaction which results in any
person or group becoming the beneficial owner of more than 40% of the shares of
Common Stock outstanding.  Upon the exercise of a limited right granted under
the Stock Plan, a participant would be entitled to receive, for each share of
Common Stock subject to such right, the excess, if any, of the highest price
paid in or in connection with such transaction over the grant price of the
limited right.

     The Stock Plan also authorizes the Committee to grant to participants
awards of Common Stock and other awards that are denominated in, payable in,
valued in whole or in part by reference to, or are otherwise based on the value
of, Common Stock ("Other Stock-Based Awards").  The Committee has discretion to
determine the participants to whom Other Stock-Based Awards are to be made, the
times at which such awards are to be made, the size of such awards, the form of
payment, and all other conditions of such awards, including any restrictions,
deferral periods or performance requirements.  The terms of the Other Stock-
Based Awards will be subject to such rules and regulations as the Committee
determines.

                                       26
<PAGE>
 
     Any award under the Stock Plan may provide that the participant has the
right to receive currently or on a deferred basis dividends or dividend
equivalents or other cash or securities payments in addition to such awards, all
as the Committee determines.

Adjustments

     If the Committee determines that any stock split, stock dividend or other
distribution (whether in the form of cash, securities or other property),
recapitalization, reorganization, merger, consolidation, split-up, spin-off,
combination, repurchase or exchange of shares, issuance of warrants or other
rights to purchase shares, or other similar corporate event affects the Common
Stock such that an adjustment is required in order to preserve the benefits
intended under the Stock Plan, then the Committee has discretion to (i) make
equitable adjustments in (a) the number and kind of shares that may be the
subject of future awards under the Stock Plan and (b) the number and kind of
shares (or other securities or property) subject to outstanding awards and the
respective grant or exercise prices thereof and (ii) if appropriate, provide for
the payment of cash to a participant.  The Committee is also authorized to make
adjustments in the terms and conditions of outstanding awards in recognition of
unusual or nonrecurring events affecting MOXY or its financial statements or
changes in applicable laws, regulations, or accounting principles whenever the
Committee determines that it is appropriate to preserve the benefits intended
under the Stock Plan.

Amendment or Termination

     The Stock Plan may be amended or terminated at any time by the Board of
Directors, except that no amendment may be made without stockholder approval if
such approval is necessary to comply with any tax or regulatory requirement,
including any approval requirement that is necessary to qualify awards as
"performance-based" compensation under Section 162(m) of the Code, if deemed
advisable by the Committee.

FEDERAL INCOME TAX CONSEQUENCES

     When an optionee exercises a non-qualified option, the difference between
the exercise price and any higher fair market value of the Common Stock on the
date of exercise will be ordinary income to the optionee (subject to
withholding) and will generally be allowed as a deduction at that time for
federal income tax purposes to MOXY.

     Any gain or loss realized by an optionee on disposition of the Common Stock
acquired upon exercise of a non-qualified option will generally be capital gain
or loss to the optionee, long-term or short-term depending on the holding
period, and will not result in any additional federal income tax consequences to
MOXY.  The optionee's basis in the Common Stock for determining gain or loss on
the disposition will be the fair market value of the Common Stock determined
generally at the time of exercise.

     When an optionee exercises an incentive stock option while employed by MOXY
or a subsidiary or within three months (one year for disability) after
termination of employment by reason of retirement or death, no ordinary income
will be recognized by the optionee at that time, but the excess (if any) of the
fair market value of the Common Stock acquired upon such exercise over the
option price will be an adjustment to taxable income for purposes of the federal
alternative minimum tax applicable to individuals.  If the Common Stock acquired
upon exercise of the incentive stock option is not disposed of prior to the
expiration of one year after the date of acquisition and two years after the
date of grant of the option, the excess (if any) of the sale proceeds over the
aggregate option exercise price of such Common Stock will be long-term capital
gain, but MOXY will not be entitled to any tax deduction with respect to such
gain. Generally, if the Common Stock is disposed of prior to the expiration of
such periods (a "Disqualifying Disposition"), the excess of the fair market
value of such Common Stock at the time of exercise over the aggregate option
exercise price (but not more than the gain on the disposition if the disposition
is a transaction on which a loss, if realized, would be recognized) will be
ordinary income at the time of such Disqualifying Disposition (and MOXY will
generally be entitled to a federal income tax deduction in a like amount).  Any
gain realized by the optionee as the result of a Disqualifying Disposition that
exceeds the amount treated as ordinary income will be capital in nature, 

                                       27
<PAGE>
 
long-term or short-term depending on the holding period. If an incentive stock
option is exercised more than three months (one year for disability) after
termination of employment, the federal income tax consequences are the same as
described above for non-qualified stock options.

     If the exercise price of an option is paid by the surrender of previously
owned shares, the basis of the previously owned shares carries over to the
shares received in replacement therefor.  If the option is a non-qualified
option, the income recognized on exercise is added to the basis.  If the option
is an incentive stock option, the optionee will recognize gain if the shares
surrendered were acquired through the exercise of an incentive stock option and
have not been held for the applicable holding period.  This gain will be added
to the basis of the shares received in replacement of the previously owned
shares.

     An employee who receives Common Stock subject to restrictions will normally
recognize taxable income on the date the shares become transferable or no longer
subject to substantial risk of forfeiture or on the date of their earlier
disposition.  The amount of such taxable income will be equal to the amount by
which the fair market value of the shares of Common Stock on the date such
restrictions lapse (or any earlier date on which the shares are disposed of)
exceeds their purchase price, if any.  An employee may elect, however, to
include in income in the year of purchase or grant the excess of the fair market
value of the shares of Common Stock (without regard to any restrictions) on the
date of purchase or grant over the purchase price. Subject to the limitations
imposed by Section 162(m) of the Code, MOXY will be entitled to a deduction for
compensation paid in the same year and in the same amount as income is realized
by the employee. Dividends currently paid to the participant will be taxable
compensation income to the participant and deductible by MOXY.

     Except as noted below, when a participant receives payment with respect to
an award granted to him other than as described in the preceding paragraphs, the
amount of cash and the fair market value of any securities received, net of any
amount paid by the participant, will be ordinary income to such participant
(subject to withholding) and, subject to the limitations provided in Section
162(m) of the Code, will generally be allowed as a deduction at that time for
federal income tax purposes to MOXY.

     MOXY believes that taxable compensation arising in connection with stock
options granted under the Stock Plan should be fully deductible to MOXY for
purposes of Section 162(m) of the Code.  Section 162(m) of the Code may limit
the deductibility of an executive's compensation in excess of $1,000,000 per
year.

     Awards under the Stock Plan that are granted, accelerated or enhanced upon
the occurrence of a change of control may give rise, in whole or in part, to
excess parachute payments within the meaning of Section 280G of the Code to the
extent that such payments, when aggregated with other payments subject to
Section 280G, exceed the limitations contained therein.  Such excess parachute
payments will be nondeductible to MOXY and subject the recipient of the payments
to a 20% excise tax.

     The foregoing discussion summarizes the federal income tax consequences of
the Stock Plan based on current provisions of the Code, which are subject to
change.  This summary does not cover any foreign, state or local tax
consequences or participation in the Stock Plan.

AWARDS UNDER THE STOCK PLAN

     The following table sets forth information with respect to the benefits
under the Stock Plan, as proposed to be amended, that were received on July 14,

5/8.  As of July 14, 1997, there were 11,554 holders of the Company's Common
Stock.

     The Company has not in the past paid cash dividends on its Common Stock and
does not expect to do so in the foreseeable future.  The Company currently
intends to reinvest its available cash in the identification, exploration and
development of additional oil and gas properties.  The decision whether or not
to pay dividends and in what amounts is solely within the discretion of the
Company's board of directors.

               MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
                      CONDITION AND RESULTS OF OPERATIONS

OVERVIEW

     MOXY is an independent oil and gas company engaged in the exploration,
development and production of oil and natural gas.  MOXY commenced operations in
May 1994 following the distribution of its common stock to the stockholders of
FTX in order to carry on substantially all of the oil and gas exploration
activities previously conducted by FTX.  MOXY and its predecessors have
conducted exploration, development and production operations offshore in the
Gulf and onshore in the Gulf Coast and other areas for more than 25 years, which
have provided MOXY with an extensive geological and geophysical database, and
significant technical and operational expertise.  MOXY expects to continue to
concentrate its efforts in this selected geographic area where its management
team has significant exploration experience.

     MOXY's business strategy is to create value for its stockholders through
the discovery of oil and gas reserves in its exploration and development
activities.  Management believes that MOXY has significant opportunities to
discover meaningful oil and gas reserves and that these opportunities can best
be achieved through the use of advanced 3-D seismic technology, applied in
conjunction with an expanded, multi-year exploration program.  Moreover, MOXY
believes that its recent and continuing acquisitions of 3-D seismic data will
continue to improve its ability to interpret subsurface geology and allow it to
develop a larger inventory of high-quality prospects that it can pursue at
offshore lease sales and through farm-in opportunities in areas where it has a
substantial geologic database and a long history of operational experience.

CAPITAL RESOURCES AND LIQUIDITY

     During 1995, MOXY established the MCN and Phillips joint ventures which
provided MOXY with an inflow of funds.  Thus far, MOXY has interests in two
producing fields in the Gulf, the Vermilion Block 160 Unit and Vermilion Block
410 field.  However, MOXY will have expended essentially all of its capital
resources by the end of 1997 and requires significant additional capital to
continue its exploration activities.  Moreover, 

                                       31
<PAGE>
 
MOXY believes that it is important to obtain sufficient capital to enable MOXY
to participate in a broader range of exploration prospects.

     In mid-1996, with the upcoming completion of the exploration portion of the
MOXY/MCN Program, management began evaluating options to obtain additional long-
term funding for its planned exploration and development activities, including
entering into one or more new long-term exploration joint ventures (MCN later
indicated that it did not wish to enter into the type of multi-year program that
MOXY desired), issuing additional equity or undertaking a business combination
with another entity.  MOXY ultimately decided to undertake the Rights Offering
(discussed below), which would allow it to recapitalize, to restructure its
current exploration and development operations, and to engage in a significantly
expanded and more diversified, multi-year exploratory drilling program.

     If MOXY shareholders approve the Recapitalization Proposal, net proceeds of
approximately $93 million would be raised by the Rights Offering to enable MOXY
to acquire MCN's interest in the MCN Producing Properties (recently purchased by
FRP) and to retire all MOXY debt.  Furthermore, the remaining cash proceeds
would provide MOXY with the funding necessary to participate in the aggregate
$200 million multi-year MOXY/FRP Exploration Program (discussed below).  MOXY
would retain a 100% interest in the MCN Producing Properties and would dedicate
all other properties which were subject to the MOXY/MCN Program to the MOXY/FRP
Exploration Program.

     MOXY and FRP plan to establish, subject to completion of the Rights
Offering, the MOXY/FRP Exploration Program to explore and develop exploratory
prospects primarily in the Gulf and onshore in the Gulf Coast area where MOXY
has significant exploration experience and a substantial geological database.
MOXY would manage the MOXY/FRP Exploration Program, selecting all prospects and
drilling opportunities, and would serve as operator of all wells drilled by the
MOXY/FRP Exploration Program.  MOXY and FRP would commit $200 million for
exploration expenses, with exploration expenses being shared 40% by MOXY and 60%
by FRP.  All revenues and other costs would be shared equally.  The MOXY/FRP
Exploration Program would include the seven leases recently purchased by MOXY
for $5.5 million at the OCS Lease Sale 166, held in March 1997 that have been
dedicated to the MOXY/MCN Program.

     If the stockholders do not approve the Rights Offering, the
Recapitalization Transactions will not be completed, and FRP will retain MCN's
interest in the MOXY/MCN Program, the MCN Producing Properties and all other
exploratory properties subject to the MOXY/MCN Program.  FRP will have the
obligation to fund, and extend credit to MOXY to fund, any exploration and
development costs that may be committed under the amended MOXY/MCN Program and
any other amounts that may be borrowed by MOXY thereunder.  FRP will not be
obligated to fund any other exploratory prospects.  As a result, MOXY will be
forced to secure alternative sources of financing to support is current
operations and fund any future exploration and development activities beyond the
financing available under the MOXY/MCN Program.  All of the net revenues
generated from MOXY's producing oil and gas properties are dedicated to repay
indebtedness incurred under the MOXY/MCN Program.  Such alternative sources
could include additional equity or debt financing, the sale of all of part of
MOXY's assets or other partnership or joint venture transactions.  There can be
no assurance that alternative financing will be available on acceptable terms,
if at all, or that MOXY will be a viable business enterprise.

     MOXY incurred $5.0 million of cash exploration and development expenditures
during the first three months of 1997, principally consisting of $1.6 million
for development at Vermilion Blocks 160 and 410, $0.4 million for lease
acquisition costs, $1.9 million in drilling and leasehold costs charged to
expense and $1.5 million of geological and geophysical costs.  Exploration
expenditures would be expected to increase following the completion of the
Rights Offering and the initiation of the MOXY/FRP Exploration Program.

OPERATIONAL ACTIVITIES

     MOXY's past exploration activities in the Gulf of Mexico have been
conducted primarily through the MOXY/MCN Program in which MOXY currently holds a
40% interest.  In July 1997, FRP acquired MCN's interest in the program, and
upon successful completion of the Rights Offering, MOXY would purchase the MCN
Producing Properties (Vermilion Blocks 160 and 410), and MOXY and FRP would
dedicate all other oil 

                                       32
<PAGE>
 
and gas properties subject to the MOXY/MCN Program to the MOXY/FRP Exploration
Program. As noted earlier, if the stockholders do not approve the Rights
Offering, the Recapitalization Transactions will not be completed, and FRP will
retain its interest in the MCN Producing Properties.

     Recent activities within the MOXY/MCN Program follow:

 .   During the fourth quarter of 1996, a development well at the Vermilion
     Block 160 field discovered new reserves from eight gas sands with
     approximately 215 feet of net pay.  Drilling on this well was completed in
     the first quarter of 1997, discovering an additional 47 feet of net pay.
     During the second quarter of 1997, a second development well to develop the
     newly discovered reserves encountered 244 feet of net gas pay from six
     sands.  A third development well is currently drilling.  The MOXY/MCN
     Program has a 28% interest in this field which is subject to re-
     determination subsequent to final development drilling.  In addition, the
     interest in two of the four blocks within the Vermilion Block 160 field
     unit is subject to a 30% net profits interest. Daily gross production at
     the Vermilion Block 160 field currently averages approximately 10 million
     cubic feet (Mmcf) of natural gas and 400 barrels of condensate.  Production
     from the new development wells is expected to commence during the second
     half of 1997.

 .    In late December 1996, installation of the production platforms and
     related facilities at the Vermilion Block 410 field was completed and
     production began from one of the two platforms.  Production began from the
     second platform in February 1997.  The MOXY/MCN Program has a 28% revenue
     interest in this field. Daily gross production currently totals
     approximately 72 Mmcf of gas.

 .    In April 1997, the MOXY/MCN Program sold its interest in West Cameron
     Block 503 for $7.2 million ($2.9 million net to MOXY) with MOXY recognizing
     a $2.3 million gain.  The proceeds were used to repay borrowings from MCN.

 .    During 1996, gas was also discovered on West Cameron Block 616 and Grand
     Isle Block 65.  During 1997, new 3-D seismic data was received and mapping
     began on West Cameron Blocks 616 and 617, as well as on Grand Isle Block
     65.  Based on the results of this new data, exploratory drilling is
     scheduled for July 1997 at Grand Isle Block 65 and is being contemplated at
     West Cameron Block 616 during the fourth quarter of 1997.

 .    During the second quarter of 1997, the MOXY/MCN Program acquired a 50%
     working interest in Eugene Island Block 18/19 from Shell Offshore Inc.
     (SOI) in exchange for a 50% interest in the MOXY/MCN Program's West Cameron
     Block 492.  SOI, as operator, is currently drilling an exploratory well on
     Eugene Island Block 19.

     MOXY's drilling activities in the onshore Gulf Coast region have taken
place through its 25% owned joint venture with Phillips, which covers a project
area in south Louisiana, as follows:

 .    In April 1997, MOXY completed drilling of an exploratory well on the North
     Bay Junop prospect, the second of two high-risk, high-potential prospects
     which have been drilled within the project area.  The well reached total
     depth but did not encounter commercial hydrocarbons in the primary
     objective zones.  MOXY completed the well in a shallower zone with
     approximately 25 feet of net pay.  The well was flow tested at a rate of
     5.3 Mmcf of gas and 93 barrels of condensate per day.  Because of the
     complexity of salt dome geology and potentially limited reservoir size,
     production performance will be required to determine the reserve volumes
     associated with this completion.  Plans to initiate production are
     currently in progress with production expected in the fourth quarter of
     1997.  MOXY continues to evaluate other leads within the project area which
     have been identified by 3-D seismic survey.

 .    MOXY completed its first exploratory well at the East Fiddler's Lake
     prospect in late 1996.  Although the well was unsuccessful in discovering
     commercial hydrocarbons, the geological data from this well assisted
     further drilling activity in the project area.

(1) Inception (May 1994) through December 31, 1994.

     MOXY's oil and gas sales began in late 1994 with the commencement of
production at the Vermilion Block 160 field.  In mid-1995, the MOXY/MCN Program
was formed, resulting in a reduction to MOXY's ownership in this field (and the
start of the management fees from the MOXY/MCN Program).  In December 1996,
production began from the first of two production platforms at the MOXY/MCN
Program's Vermilion Block 410 field, with production from the second platform
commencing in February 1997.  As noted above, upon successful completion of the
Rights Offering, MOXY intends to purchase MCN's interest in the Vermilion Block
160 and 410 fields from FRP.  See the unaudited Pro Forma Results of Operations
contained in this proxy statement.

     General and administrative expenses totaled $0.7 million for the three-
month 1997 and 1996 periods, compared with $2.6 million in 1996, $3.7 million in
1995 and $2.3 million in the 1994 period.  The decline from 1995 resulted from
steps taken in the third quarter of 1995 to reduce costs. These actions included
a reduction in the number of employees and in the costs of consulting
arrangements and administrative and managerial services.

     As a result of anticipated future exploration expenditures, MOXY expects to
continue to report operating losses for at least the near future.

ENVIRONMENTAL

Although MOXY has no known environmental liabilities,  increasing emphasis on
environmental matters could result in additional costs, which would be charged
against MOXY's operations in future periods.  Present and future environmental
laws and regulations applicable to MOXY's operations could require substantial
capital expenditures or could adversely affect its operations in other ways that
cannot be accurately predicted at this time.

CAUTIONARY STATEMENT

Management's discussion and analysis contains certain forward-looking
statements.  Important factors that might cause future results to differ from
these projections are described in more detail under the heading "Cautionary
Statement" in MOXY's Form 10-K for the year ended December 31, 1996.

                CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

SERVICES AGREEMENT

     Other than those functions performed by the Company's employees or provided
under third party contracts, since January 1, 1996 a substantial portion of the
services necessary for the business and operations of the Company, including
certain executive, technical, administrative, accounting, financial, tax and
other services have been performed by FMS, a corporation 50% owned by each of
FTX and Freeport-McMoRan Copper & Gold Inc., pursuant to the Services Agreement.
Prior to 1996, substantially the same services were provided by FTX.  Since
September 1995 these services have been provided for a fixed annual fee of $1.0
million, subject to annual cost of living increases beginning in the first
quarter of 1997.  Prior to September 1995, the cost of such services was
provided by FTX as determined and allocated by FTX.  For the year ended December
31, 1996, the Company incurred $1.0 million of expenses under its agreement with
FMS.  The Services Agreement is terminable by the Company at any time upon 90
days notice.

OIL AND GAS PROPERTIES

     In June 1996, FRP acquired a 25% leasehold in interest in an oil and gas
venture to explore a project area in Terrebonne Parish, Louisiana.  In
connection with the acquisition of this interest, FRP reimbursed the Company
$2.1 million for certain costs previously incurred in the project area.  FRP
acquired its interest on the same proportionate basis as Phillips, which owns a
50% interest and is the operator of the joint venture.

     In February 1997, FRP agreed to acquire an interest in leases acquired by
the Company at the federal offshore lease sale held in March 1997.  At the lease
sale, the Company was high bidder on seven offshore Gulf of Mexico tracts, with
bids totaling $5.5 million.  MOXY and FRP have dedicated these leases to the
MOXY/MCN Program.  Upon completion of the Rights Offering, these leases will be
dedicated to the MOXY/FRP Exploration Program.

     Upon completion of the Rights Offering, MOXY and FRP will enter into an
agreement pursuant to which MOXY will market all of FRP's oil and gas
production, including production from properties included in the MOXY/FRP
Exploration Program and production from FRP's other properties, including its
interest in the Main Pass development.

     During 1996, Mr. Day participated directly or indirectly through various
entities, on substantially the same basis as other parties, in exploration and
development operations on certain properties owned or operated by the Company.
Mr. Day and such entities have ownership interests in such properties ranging
generally from 12.5% to 25%.  Mr. Day's and such entities' share of expenditures
for exploration and development operations during 1996 amounted to approximately
$200,000.

MCN PROPERTIES; STANDBY PURCHASE AGREEMENT

     On July 14, 1997, MOXY entered into an agreement to acquire the MCN
Producing Properties from FRP concurrently with the closing of the Standby
Commitment for $26.0 million, as adjusted for net revenues and development and
operating costs attributable to the MCN Producing Properties from April 1, 1997
until MOXY's acquisition of these properties, plus interest calculated on the
daily outstanding balance of the $26.0 million purchase price, as adjusted, from
_______, 1997 until MOXY's acquisition of the properties at an annual rate
publicly announced by The Chase Manhattan Bank from time to time plus 2%.  At
the same time MOXY will also repay to FRP all amounts loaned to MOXY under the
MOXY/MCN Program.  See "Use of Proceeds."

     Pursuant to the Standby Purchase Agreement, MOXY has agreed to pay a
Standby Fee of $6.0 million to FRP upon the closing of the Standby Commitment.
In addition, MOXY has granted to FRP the FRP Purchase Option, pursuant to which
FRP may acquire additional shares of Common Stock at the Subscription Price to
increase its ownership position in MOXY up to 30%, if it does not acquire at
least 30% of the outstanding Common Stock pursuant to the Standby Commitment.

                                       35
<PAGE>
 
     Following the consummation of the Rights Offering and the transactions
contemplated by the Standby Purchase Agreement, FRP may acquire a controlling
interest in MOXY or upon exercise of the FRP Purchase Option, may acquire a
sufficient ownership interest to be able to significantly influence the business
policies and affairs of the Company.  If FRP acquires a majority of the
outstanding Common Stock, it will be in a position to control the election of
the Company's directors and to otherwise direct the business policies and
affairs of the Company.  See "Risk Factors - Potential Change of Control of the
Company."  FRP and the Company will enter into a Stockholder Agreement providing
that the Company will not, without the approval of the Independent Committee
take certain actions, including (i) repurchase any Common Stock, (ii) certain
transactions with FRP involving aggregate payments in excess of $5 million,
(iii) enter into any "Rule 13e-3 transaction" within the meaning of Rule 13e-3
under the Exchange Act, (iv) amend the term of the MOXY/FRP Exploration Program,
(v) amend, modify or grant a waiver under MOXY's Preferred Rights Agreement, the
Participation Agreement or the Stockholder Agreement and (vi) in connection with
any merger or business in combination involving MOXY and a third party, treat
FRP and the other holders of Common stock on other than equivalent terms.
Moreover, the Company intends to conduct all such transactions on an arm's
length basis.  See "Description of Capital Stock - Stockholder Agreement and
Registration Rights."

                         DESCRIPTION OF CAPITAL STOCK

        The Company's Certificate of Incorporation authorizes the issuance of
50,000,000 shares of preferred stock, $.01 par value per share (the "Preferred
Stock"), and 150,000,000 shares of Common Stock. As of the date of this Proxy
Statement, there were ____________ shares of Common Stock issued and
outstanding.  The following summary is qualified by reference to the Certificate
of Incorporation.

COMMON STOCK

        Subject to the rights of the holders of any Preferred Stock which may be
outstanding, each holder of Common Stock on the applicable record date will be
entitled to receive such dividends as may be declared by the Board of Directors
out of funds legally available therefor, and, in the event of liquidation, to
share pro rata in any distribution of the Company's assets after payment or
providing for the payment of liabilities.

        Each holder of Common Stock is entitled to one vote for each share held
of record  on the applicable record date on all matters presented to a vote of
stockholders, including the election of directors. Holders of Common Stock have
no cumulative voting rights or preemptive rights to purchase or subscribe for
any stock or other securities and there are no conversion rights  with respect
to such stock.  Additional shares of authorized Common Stock may be issued
without stockholder approval.

PREFERRED STOCK

        The Company's Board of Directors has the authority to issue shares of
Preferred Stock in one or more series and to fix, by resolution, the voting
powers, which may be full or limited or no voting powers, designations,
preferences and relative, participating, optional or other special rights and
the qualifications, limitations or restrictions thereof, without any further
vote or action by the stockholders.  Any shares of Preferred Stock so authorized
and issued would have priority over the Common Stock with respect to dividend or
liquidation rights.

CERTAIN EFFECTS OF AUTHORIZED BUT UNISSUED STOCK

        The authorized but unissued shares of Common Stock and Preferred Stock
will be available for future issuance without shareholder approval.  These
additional shares may be utilized for a variety of proper corporate purposes,
including raising additional capital.

        One of the effects of the existence of unissued and unreserved Common
Stock and Preferred Stock may be to enable the Board of Directors to issue
shares to persons friendly to current management, which could render more
difficult or discourage an attempt to obtain control of the Company by means of
a merger, tender offer, proxy contest or otherwise, and thereby protect the
continuity of the Company's 

                                       36

management. Issuance of such stock might, under certain circumstances, deter the
acquisition of the Company or its securities by a person concerned about the
terms or effect of such stock.

CERTAIN PROVISIONS OF THE COMPANY'S CERTIFICATE AND BYLAWS AND DELAWARE LAW

        Classification of Directors; Removal.  The Certificate provides that
subject to the rights to elect additional directors that may be granted to
holders of any class or series of Preferred Stock, the number of directors shall
be fixed from time to time as provided in the Bylaws, but may not consist of
less than three persons.  The Certificate further provides that the directors,
other than those who may be elected by the holders of any class or series of
Preferred Stock, shall be classified, with respect to the time for which they
severally hold office, into three classes, designated Class I, Class II and
Class III, as nearly equal in number as possible, and that one class shall be
elected each year and serve for a three-year term.

        Board Vacancies.  The Certificate also provides that all vacancies on
the Company's Board of Directors, including any vacancies resulting from an
increase in the number of directors, may be filled by a majority of the
remaining directors even if that number is less than a quorum.  The affirmative
vote of 85% or more of the Company's voting stock is required to amend, alter,
change or repeal the foregoing provisions. The Bylaws require notice to the
Company not less than 60 days nor more than 90 days prior to any stockholder
meeting to elect directors or make any nomination for the Board of Directors.

        Stockholder Meetings.  The Certificate provides that any action required
or permitted to be taken by stockholders must be effected at a duly called
annual or special meeting and may not be effected by written consent.  Under the
Certificate, except as described below, stockholders are not permitted to call
special meetings of stockholders or to require the Board to call a special
meeting of stockholders and a special meeting of stockholders may be called only
by a majority of the entire Board, the Chairman of the Board or the President.
The Bylaws further require that the Board must receive notice of stockholder
proposals at least 60 days but not more than 90 days prior to any meeting of
stockholders at which such proposal is intended to be presented.  The Board may
reject any such proposals that are not made in accordance with certain
procedures set forth in the Bylaws or that are not a proper subject for
stockholder action in accordance with the provisions of applicable law.

        Stockholder Approval of Combinations; Fair Price Provision.  The
Certificate of Incorporation provides that the approval of the holders of 85% of
the Common Stock is required to approve (a) any merger or consolidation of the
Company or any of its subsidiaries with or into any person or entity, or any
affiliate thereof, other than FTX or any of its affiliates or associates,
including FRP (an "Interested Party"), who was within the two years prior to the
relevant transaction a beneficial owner of 20% or more of the Common Stock, (b)
any merger or consolidation of an Interested Party with or into the Company or
any of its Subsidiaries, (c) any sale, lease, pledge, transfer or other
disposition of more than 10% of the fair market value of the assets of the
Company or any of its subsidiaries in one or more transactions involving an
Interested Party, (d) the adoption of any plan or proposal for liquidation or
dissolution of the Company proposed by or on behalf of any Interested Party, (e)
the issuance or transfer by the Company or any of its subsidiaries of securities
having a fair market value of $1,000,000 or more to any Interested Party or (f)
any recapitalization, reclassification, merger or consolidation of the Company
or any of its subsidiaries which would increase an Interested Party's voting
power in the Company or such subsidiary; provided that the 85% voting
requirement shall not be applicable if (i) a majority of a vote of the Company's
Continuing Directors (defined as a director, and any successor thereof, who is
not an affiliate of an Interested Party and who was a member of the Board prior
to the time the Interested Party involved in any of the foregoing transactions
became an Interested Party) has approved the transaction, (ii) the transaction
is between the Company and any of its subsidiaries or between any of its
subsidiaries or (iii) the transaction is a merger or consolidation and the
consideration to be received by the Company's stockholders is at least as high
as the highest price per share paid by the Interested Party for the Common Stock
during the prior two years.

        Delaware Law.  The Company is incorporated under the laws of Delaware.
Section 203 of the Delaware General Corporation Law prevents an "interested
stockholder" (defined as a stockholder owning 15% or more of a corporation's
voting stock) from engaging in a business combination with such corporation for
a period of three years from the date such stockholder became an interested
stockholder unless (a) the 

                                       37
<PAGE>
 
corporation's board of directors had earlier approved either the business
combination or the transaction by which the stockholder became an interested
stockholder, or (b) upon attaining that status, the interested stockholder had
acquired at least 85% of the corporation's voting stock (not counting shares
owned by persons who are directors and also officers), or (c) the business
combination is later approved by the board of directors and authorized by a vote
of two-thirds of the stockholders (not including the shares held by the
interested stockholder). Under Section 203, the restrictions described above do
not apply to certain business combinations proposed by an interested stockholder
following the announcement or notification of one of certain extraordinary
transactions involving the corporation and a person who had not been an
interested stockholder during the previous three years or who become an
interested stockholder with the approval of a majority of the corporation's
directors, if such extraordinary transaction is approved or not opposed by a
majority of the directors who were directors prior to any person becoming an
interested stockholder during the previous three years or were recommended for
election or elected to succeed such directors by a majority of such directors.
Prior to entering the Standby Purchase Agreement, MOXY's board of directors
approved the proposed transaction with FRP and thereby excluded FRP from the
operation of Section 203 of the Delaware General Corporation Law.

PREFERRED STOCK PURCHASE RIGHTS

        In May 1994, the Company's Board of Directors declared and paid a
dividend of one preferred stock purchase right (a "Preferred Right") for each
outstanding share of Common Stock.  Each Preferred Right entitles the registered
holder to purchase from the Company one one-hundredth of a share of Series A
Participating Cumulative Preferred Stock, par value $0.01 per share (the "Series
A Preferred Stock"), at an initial purchase price of $10.00 (the "Purchase
Price"), subject to adjustment.  The terms of the Preferred Rights are set forth
in the Preferred Rights Agreement between the Company and Mellon Securities
Trust Company, as Preferred Rights Agent (the "Preferred Rights Agreement").

        As soon as practicable after the earlier of (i) the tenth day (or such
later date as may be designated by a majority of the Continuing Directors (as
hereinafter defined)) after the date (the "Stock Acquisition Date") of the first
public announcement that a person or group of affiliated or associated persons
other than the Company, any of its subsidiaries or any employee benefit plan of
the Company or any of its subsidiaries has acquired beneficial ownership (as
defined in the Preferred Rights Agreement) of 15% or more of the outstanding
shares of Common Stock  (an "Acquiring Person") and (ii) the tenth business day
(or such later date as may be designated by a majority of the Continuing
Directors) after the date of the commencement of a tender or exchange offer by
any person if, upon consummation thereof, such person would be an Acquiring
Person (the earlier of (i) and (ii) being referred to as the "Preferred Rights
Distribution Date"), the Preferred Rights Agent will send to each record holder
of Common Stock as of the close of business on the Preferred Rights Distribution
Date, one or more Preferred Right Certificates evidencing one Preferred Right
(subject to adjustment as provided in the Preferred Rights Agreement) for each
share of Common Stock.  The Preferred Rights are not exercisable until the
Preferred Rights Distribution Date and will expire at the close of business on
May 20, 2004, unless previously redeemed or exchanged by the Company as
described below.

        If a person becomes an Acquiring Person, each holder of a Preferred
Right (other than Preferred Rights that are, or under certain circumstances
specified in the Preferred Rights Agreement were, beneficially owned by an
Acquiring Person (which will thereafter be void)) will thereafter have the right
to receive upon exercise thereof at the then current Purchase Price, Common
Stock having a market value equal to two times the Purchase Price.

        If at any time after any person has become an Acquiring Person (i) the
Company is acquired in a merger or other business combination transaction in
which the Company is not the surviving corporation or the Common Stock is
changed or converted or (ii) 50% or more of the Company's assets or earning
power is sold, each holder of a Preferred Right will thereafter have the right
to receive, upon exercise thereof at the then current Purchase Price, common
stock of the acquiring company having a market value equal to two times the
Purchase Price.

                                       38
<PAGE>
 
        At any time after any person has become an Acquiring Person (but before
such person becomes the beneficial owner of  50% or more of the outstanding
shares of Common Stock), the Board of Directors of the Company may, at its
option, exchange all or part of the Preferred Rights (other than Preferred
Rights that are, or under certain circumstances were, beneficially owned by an
Acquiring Person) for shares of Common Stock at an exchange ratio of one share
of Common Stock per Preferred Right.  The Preferred Rights may, at the option of
the Board of Directors, be redeemed in whole, but not in part, at a price of
$.01 per Preferred Right at any time no later than the tenth day after the Stock
Acquisition Date (or such later date as a majority of the Continuing Directors
may designate).  Under certain circumstances set forth in the Preferred Rights
Agreement, the decision to redeem shall require the concurrence of a majority of
the Continuing Directors. Immediately upon the requisite action of the Board of
Directors ordering exchange or redemption of the Preferred Rights, the Preferred
Rights will terminate, and thereafter the only right of the holders of Preferred
Rights will be to receive shares of Common Stock or the redemption price, as the
case may be.

        "Continuing Director" means any member of the Board of Directors who was
a member of the Board prior to the time an Acquiring Person becomes such, or any
person who is subsequently elected to the Board if such person is recommended or
approved by a majority of the Continuing Directors.  Continuing Directors do not
include an Acquiring Person, or an affiliate or associate of an Acquiring
Person, or any representative of the foregoing.

        The Purchase Price payable, and the number of shares of Series A
Preferred Stock or other securities or property issuable, upon exercise of the
Preferred Rights are subject to adjustment in certain circumstances.  Until a
Preferred Right is exercised, the holder will, as a result thereof, have no
rights as a stockholder of the Company, including the right to vote or to
receive dividends.  Stockholders may, depending upon the circumstances,
recognize taxable income in the event that the Preferred Rights become
exercisable for Series A Preferred Stock or other consideration as set forth
above.  The federal income tax consequences of any event or transaction
involving the Preferred Rights other than the payment of the Preferred Rights
dividend in May, 1994, is uncertain and tax counsel expresses no opinion of the
federal income tax consequences of such events or transactions.

        Prior to the Preferred Rights Distribution Date, the Preferred Rights
Agreement may, if the Company so directs, be amended by the Company and the
Preferred Rights Agent in any manner that the Company may deem necessary or
desirable without the approval of any holders of Common Stock.  After the
Preferred Rights Distribution Date, the Preferred Rights Agreement may be
amended in any respect that does not adversely affect Preferred Rights holders;
provided that after a person becomes an Acquiring Person, any amendment requires
the concurrence of a majority of the Continuing Directors.

        The Preferred Rights have certain anti-takeover effects.  The Preferred
Rights may cause substantial dilution to a person or group that attempts to
acquire the Company without a condition to such an offer that a substantial
number of Preferred Rights be acquired or the Preferred Rights be redeemed or
otherwise not apply.  The Company's ability to amend the Preferred Rights
Agreement may, depending upon the circumstances, increase or decrease the anti-
takeover effects of the Preferred Rights.  The Preferred Rights do not prevent
the Board of Directors of the Company from approving any merger or other
business combination (under some circumstances, with the concurrence of the
Continuing Directors) since the Preferred Rights may be redeemed by the Board of
Directors as described above.

        Prior to entering into the Standby Purchase Agreement, MOXY amended the
Preferred Rights Agreement to exclude FRP and its affiliates and associates from
the operation of the Preferred Rights Agreement.

STOCKHOLDER AGREEMENT AND REGISTRATION RIGHTS

        Upon completion of the Rights Offering and the transactions contemplated
by the Standby Purchase Agreement, MOXY and FRP will enter into a Stockholder
Agreement pursuant to which MOXY (i) will implement certain corporate governance
provisions designed to protect the other stockholders of MOXY, (ii) will grant
to FRP the right to elect a certain number of directors if it owns more than 10%
but less than a 

                                       39
<PAGE>
 
majority of the outstanding Common Stock and (iii) will grant certain
registration rights with respect to the shares of Common Stock that are
purchased by FRP pursuant to the Standby Purchase Agreement.

        Pursuant to the Stockholder Agreement MOXY will agree at all times to
have at least two Independent Directors and maintain the Independent Committee.

        Until the date on which FRP ceases to beneficially own at least 10% of
the outstanding Common Stock, MOXY shall not take any of the following actions
without the approval of the Independent Committee: (a) repurchase any
outstanding shares of Common Stock; (b) enter into (i) any sale, lease, transfer
or other disposition by MOXY of any of its properties or assets to, (ii) any
purchase of property or assets by MOXY from, (iii) any investment by MOXY in,
(iv) any agreement by MOXY with or for the benefit of, or (v) any other
transaction with one or more of its affiliates, that involves aggregate payments
in excess of $5 million; (c) enter into any "Rule 13e-3 transaction" within the
meaning of Rule 13e-3 under the Exchange Act; (d) amend, modify or grant any
waiver under the Preferred Rights Agreement, the Participation Agreement or the
Stockholder Agreement; or (e) in connection with any merger or business
combination involving MOXY and a third party, treat FRP and the other
stockholders on other than equivalent terms.

        Until the date on which FRP ceases to own, directly or indirectly, at
least 10% of the outstanding voting stock of MOXY, FRP shall not take either of
the following actions without the approval of the Independent Committee: (i)
purchase, acquire, agree to acquire or offer to acquire beneficial ownership of
any additional shares of Common Stock (other than through open-market purchases
that do not constitute a Rule 13e-3 transaction within the meaning of Rule 13e-3
under the Exchange Act), or (ii) enter into, propose to enter into, solicit or
support any merger or business combination or similar transaction involving FRP
and MOXY.

        Pursuant to the Stockholder Agreement, FRP will be entitled to demand
registration rights with respect to any shares of Common Stock that it  owns;
provided that FRP registers no less than 10% of the outstanding Common Stock
pursuant to each stock registration and that MOXY not be required to effect more
than one such registration in any 12-month period nor more than three such
registrations in the aggregate. In addition, if the Company proposes to register
any Common Stock under the Securities Act in connection with a public offering,
FRP may require MOXY to include all or a portion of the shares owned by FRP at
that time.  MOXY has agreed to pay all the expenses of any registration under
the Stockholder Agreement, other than underwriters' discounts and commissions,
and to indemnify FRP for certain liabilities in connection with any such
registration.


                   SECURITY OWNERSHIP OF CERTAIN BENEFICIAL
                             OWNERS AND MANAGEMENT

the Company's Common Stock by (i) each director of the Company, (ii) each
executive officer, (iii) all directors and executive officers of the Company as
a group, and (iv) the persons known by the Company to be beneficial owners of
more than five percent of the Company's outstanding Common Stock determined in

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

TO THE STOCKHOLDERS AND BOARD OF DIRECTORS OF McMoRan OIL & GAS CO.:

  We have audited the accompanying balance sheets of McMoRan Oil & Gas Co. (a
Delaware Corporation) as of December 31, 1996 and 1995 and the related
statements of operations and cash flow for the years ended December 31, 1996 and
1995 and for the period from inception through December 31, 1994.  These
financial statements are the responsibility of the Company's management.  Our
responsibility is to express an opinion on these financial statements 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 financial position of McMoRan Oil & Gas Co. as of
December 31, 1996 and 1995 and the results of its operations and its cash flow
for the years ended December 31, 1996 and 1995 and for the period from inception
through December 31, 1994 in conformity with generally accepted accounting

1.  ORGANIZATION

McMoRan Oil & Gas Co. (MOXY) was formed in 1994 as a wholly owned subsidiary of
Freeport-McMoRan Inc. (FTX).  In May 1994, FTX distributed one MOXY common share
for each ten FTX common shares.  The net assets transferred, at FTX's historical
cost, follow (in thousands):

2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

USE OF ESTIMATES.  The preparation of financial statements in conformity with
generally accepted accounting principles requires management to make estimates
and assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period.  Actual results could differ from those estimates.

CASH AND CASH EQUIVALENTS.  Highly liquid investments purchased with a maturity
of three months or less are considered cash equivalents.

EXPLORATION AND DEVELOPMENT COSTS.  MOXY follows the successful efforts method
of accounting for its oil and gas operations.  Costs of exploratory wells are
capitalized pending determination of whether the wells find proved reserves.
Costs of leases, productive exploratory wells and development activities are
also capitalized.  Other exploration costs are expensed.  Depreciation and
amortization is determined on a field-by-field basis using the unit-of-
production method.  Gains or losses are included in earnings when properties are
sold.

  In 1995, the Financial Accounting Standards Board issued Statement No. 121
(FAS 121) which requires a reduction of the carrying amount of long-lived assets
to fair value when events indicate that the carrying amount may not be
recoverable.  Measurement of the impairment loss is based on the fair value of
the asset.  Generally, MOXY determines fair value using valuation techniques
such as expected future cash flows.  MOXY adopted FAS 121 effective January 1,
1995, and since that time has not incurred any impairment losses.

FINANCIAL INSTRUMENTS.  The carrying amounts of receivables, other current
assets and accounts payable reported in the balance sheet approximate fair
value.  The production loans interest rate is variable (Note 3) and thus
approximates fair value.

EARNINGS PER SHARE.  In February 1997, the Financial Accounting Standards Board
issued Statement No. 128 (FAS 128), "Earnings Per Share", which simplifies the
computation of earnings per share.  FAS 128 is effective for financial
statements issued for periods ending after December 15, 1997 and requires
restatement for all prior period earnings per share data presented.  Earnings
per share calculated in accordance with FAS 128 would have been unchanged for
the periods presented.

3.  EXPLORATION AGREEMENTS

In September 1995, MOXY entered into an agreement with MCN establishing a $65
million oil and gas exploration and development program in the offshore Gulf of
Mexico area.  Revenues and costs are shared 40 percent by MOXY and 60 percent by
MCN.  MCN is funding its 60 percent share of the expenditures and is loaning
funds for MOXY's 40 percent share at prime plus two percent.  MOXY's share of
future net revenues from program properties is dedicated to repay borrowings.
MOXY is not otherwise obligated to repay these borrowings.  As of December 31,
1996, MOXY had $12.8 million of borrowings outstanding from MCN, with an
additional $6.6 million of borrowings available for past expenditures.

  In June 1995, MOXY and Phillips Petroleum Company (Phillips) entered into an
exploration agreement covering a project area in south Louisiana.  MOXY conveyed
one-half of its interest in the area to Phillips for $3.8 million.  In June
1996, MOXY sold one-half of its remaining 50 percent leasehold interest to
Freeport-McMoRan Resource Partners, Limited Partnership (FRP), an affiliate of
MOXY, for 

                                      F-5
<PAGE>
 
$2.1 million. This amount represented the reimbursement for certain costs
previously incurred by MOXY in connection with this project area and was
recorded as a reduction to exploration expenses. MOXY sold the interest to FRP
on the same proportionate basis as the prior Phillips sale. The project area,
with the exception of the North Bay Junop and the East Fiddlers Lake prospects
(discussed earlier), is subject to a possible 25 percent participation by a
mineral rights owner.

4.  TRANSACTIONS WITH FTX AND EMPLOYEE BENEFITS

MANAGEMENT SERVICES.  FTX provides certain management and administrative
services for MOXY.  During 1995, MOXY restructured its management services
agreement with FTX to provide specified services for an annual fee of $1.0
million.  Costs of services provided by FTX, included in general and
administrative expenses, totaled $1.0 million in 1996, $1.3 million in 1995 and
$1.2 million in the 1994 period.

  MOXY's contract for geological and geophysical services with CLK Company (CLK)
was amended during 1997 to provide for an annual retainer fee of $2.4 million
($0.5 million of the annual fee paid in MOXY common stock), plus certain
expenses and an overriding royalty interest in prospects accepted by MOXY.
Costs of services provided by CLK, included in exploration expenses, totaled
$3.1 million in 1996, $3.5 million in 1995 and $3.9 million in 1994.

STOCK OPTIONS.  MOXY's Stock Option Plan and Stock Option Plan for Non-Employee
Directors (the Plans) authorize MOXY to grant stock options to purchase up to
1.25 million shares of MOXY stock at no less than market value at time of grant.
Generally, stock options are exercisable in 25 percent annual increments
beginning one year from the date of grant and expire 10 years after the date of
grant.  Also, in connection with the FTX distribution of MOXY shares, stock
options were granted to employees and directors of FTX.  A summary of stock
options outstanding follows:

                          ============                       ==========
</TABLE>

  MOXY has adopted the disclosure-only provisions of FAS 123 and continues to
apply APB Opinion No. 25 and related interpretations in accounting for its
stock-based compensation plans. Accordingly, no compensation cost has been
recognized for MOXY's fixed stock option grants. Had compensation cost for
MOXYs' fixed stock option grants been determined based on the fair value at the
grant dates for awards under those plans consistent with FAS 123, MOXY's pro
forma net loss would have been $10.1 million ($0.73 per share) in 1996 and $14.7
million ($1.06 per share) in 1995. For the pro forma computations, the fair
values of the fixed option grants were estimated on the dates of grant using the

                                      F-6
<PAGE>
 
Black-Scholes option pricing model. The weighted average fair value for fixed
stock option grants was $1.69 per option in 1996 and $2.15 per option in 1995.
The weighted average assumptions used include a risk-free interest rate of 6.6
percent in 1996 and 6.4 percent in 1995, expected volatility of 45 percent in
1996 and 60 percent in 1995 and expected lives of 10 years. The pro forma
effects on net income for 1996 and 1995 are not representative of future years
because they do not take into consideration grants made prior to 1995. No other
discounts or restrictions related to vesting or the likelihood of vesting of
fixed stock options were applied.

5.  INCOME TAXES

MOXY has $26.5 million of net deferred tax assets as of December 31, 1996
resulting from temporary differences related to MOXY's and its predecessor
entities' exploration activities.  MOXY has provided a valuation allowance equal
to these tax assets because of the expectation of incurring tax losses for at
least the near future.

6.  COMMITMENTS AND CONTINGENCIES
COMMITMENTS.  MOXY has expenditure commitments of approximately $8.7 million in
1997.

ENVIRONMENTAL.  Although MOXY has no known environmental liabilities, increasing
emphasis on environmental matters could result in additional costs, which would
be charged against MOXY's operations in future periods.  Present and future
environmental laws and regulations applicable to MOXY's operations could require
substantial capital expenditures or could adversely affect its operations in
other ways that cannot be accurately predicted at this time.

7.  SUPPLEMENTARY OIL AND GAS INFORMATION (UNAUDITED)
The supplementary information presented below is prepared in accordance with
requirements prescribed by the Financial Accounting Standards Board.

PROVED OIL AND GAS RESERVES.  Proved oil and gas reserves at December 31, 1996,
have been estimated by independent petroleum engineers in accordance with
guidelines established by the Securities and Exchange Commission (SEC).  Thus,
the following reserve estimates are based upon existing economic and operating
conditions; they are only estimates and should not be construed as being exact.
MOXY's 1996 proved reserves are located in offshore United States waters.  Oil,
including condensate and plant products, is stated in thousands of barrels and
natural gas is in millions of cubic feet.

STANDARDIZED MEASURE OF DISCOUNTED FUTURE NET CASH FLOWS FROM PROVED OIL AND GAS
RESERVES.

MOXYs standardized measure of discounted future net cash flows and changes
therein relating to proved oil and gas reserves were computed using reserve
valuations based on regulations prescribed by the SEC.  These regulations
provide for the use of current oil and gas prices (escalated only when known and
determinable price changes are provided by contract and law) in the projection
of future net cash flows.

    Oil and natural gas prices have declined subsequent to December 31, 1996.
The future cash flows from proved reserves presented above do not reflect this
decline.

    The reserve and cash flow information above includes amounts attributable to
MOXY's interest in West Cameron Block 503, which in March 1997 MOXY agreed to
sell for $2.9 million. Proved undeveloped reserves applicable to MOXY's interest
in this field totaled approximately 16 thousand barrels of oil and 3,300 million
cubic feet of gas with estimated discounted net cash flows of $3.4 million. MOXY
would recognize a gain of approximately $2.3 million upon completion of this
sale.

               NOTES TO UNAUDITED PRO FORMA FINANCIAL STATEMENTS


          The accompanying Pro Forma Statements of Operations have been prepared
assuming the transactions discussed below occurred on January 1, 1996, whereas
the Pro Forma Balance Sheet assumes the transactions occurred on March 31, 1997.
The pro forma financial statements are not necessarily indicative of the actual
results that would have been achieved nor are they indicative of future results.

1.  ACQUISITION OF THE MCN PRODUCING PROPERTIES

          In July 1997, FRP acquired MCNs interest in the MOXY/MCN Program.  In
July 1997, MOXY entered into an agreement with FRP pursuant to which MOXY will
acquire the producing oil and gas properties (the MCN Producing Properties)
developed as part of the MOXY/MCN Program for $26.0 million, subject to
adjustment, and repay all indebtedness incurred by MOXY under the MOXY/MCN
Program.

          The income statement information represents the historical revenues
and direct operating expenses of the MCN Producing Properties for the periods
presented.

          The balance sheet information represents the acquisition of the MCN
Producing Properties at FRPs purchase price and the repayment of MOXYs debt
under the MOXY/MCN Program.

2.  OTHER ADJUSTMENTS

a.   MOXY intends to consummate the Rights Offering (as discussed earlier in
     this document) whereby additional MOXY common stock would be issued
     sufficient to raise $100 million ($93 million after offering expenses and
     the FRP Standby Fee).

b.   Represents the sale of MOXYs interest in the West Cameron Block 503 field
     in April 1997 for $2.9 million, with a gain of $2.3 million to retained
     earnings and a reduction to oil and gas properties.  Proceeds from the sale
     were used to reduce the amount of indebtedness to MCN.

c.   Upon the initiation of the MOXY/FRP Exploration Program, MOXYs level of
     general and administrative expense will change, with MOXY allocating
     certain exploration and administrative expenses to FRP.  Because the level
     of expense and allocation is not known at this time, no pro forma
     adjustment has been reflected.

d.   Represents the depreciation and amortization expense calculated using the
     acquisition price of the MCN Producing Properties (Note 1).

e.   Represents the elimination of the historical interest expense (Note 1).

f.   Upon completion of the Rights Offering and the acquisition of the MCN
     Producing Properties, MOXY will have significant additional cash resources.
     In accordance with SEC regulations concerning pro forma financial
     statements, MOXY has not reflected any additional investment income.
     However, if MOXY had invested this excess cash and earned income at MOXYs
     historical rate for short-term investments, pro forma net loss would have
     been $6.1 million ($0.14 per share) for 1996 and $0.8 million ($ 0.02 per
     share) for the 1997 period.

                   REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

To the Stockholders and Board of Directors of
McMoRan Oil & Gas Co.:

    We have audited the accompanying statements of gross oil and gas revenues
and direct operating expenses of the MCN Producing Properties (the Producing
Properties) to be acquired by McMoRan Oil & Gas Co. (see Note 1) for the year
ended December 31, 1996 and for the period from the inception of the MOXY/MCN
Program (September 19, 1995) through December 31, 1995.  These statements are
the responsibility of management.  Our responsibility is to express an opinion
on the statements 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 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 presentation of the statements.
We believe our audits provide a reasonable basis for our opinion.

    The accompanying statements present only the gross oil and gas revenues and
direct operating expenses (see Note 1) and are not intended to be a complete
presentation of the revenues and expenses of the Producing Properties.

    In our opinion, the statements referred to above present fairly, in all
material respects, the gross oil and gas revenues and direct operating expenses
of the Producing Properties for the year ended December 31, 1996 and for the
period from the inception of the MOXY/MCN Program through December 31, 1995, in
conformity with generally accepted accounting principles.

    The following statements of gross oil and gas revenues and direct operating
expenses of the MCN Producing Properties (the Producing Properties) to be
purchased by MOXY for the year ended December 31, 1996 and for the period from
the inception of the MOXY/MCN Program through December 31, 1995 have been
audited by Arthur Andersen LLP, independent public accountants, as set forth in
their accompanying report.  The statements are presented to provide historical
data about the Producing Properties to be acquired and may not be indicative of
future results of operations of the Producing Properties.

    Separate financial statements for the Producing Properties have never been
prepared.  Depreciation, depletion and amortization has not been included
because the historical expenses incurred by the predecessor owner may not be
comparable to amounts to be incurred by MOXY in future periods.  Further, it is
not possible to make a practicable or objective determination of the portion of
general or administrative expenses or other indirect expenses which were
attributable to the Producing Properties and any such allocation would not be
indicative of the level of such expense to be incurred in the future.  In
addition, a provision for income taxes has not been included because the tax
position of the predecessor owner will not affect MOXY's future tax provisions.

               NOTES TO STATEMENTS OF GROSS OIL AND GAS REVENUES
         AND DIRECT OPERATING EXPENSES OF THE MCN PRODUCING PROPERTIES

1.  BASIS OF PRESENTATION

    In September 1995, MOXY established an exploratory drilling program with MCN
owned 40% by MOXY and 60% by MCN.  On July 14, 1997, MOXY entered into an
agreement with FRP pursuant to which MOXY will acquire MCN's interest in the
producing oil and gas properties (the Producing Properties) developed as part of
MOXY's exploratory drilling program with MCN for $26.0 million.

    The accompanying statements of gross oil and gas revenues and direct
expenses, which are prepared on the successful efforts basis of accounting,
relate to the interests in producing oil and gas properties described above and
may not be representative of future operations.  The statements do not include
Federal and state income taxes, interest, depreciation, depletion and
amortization or general and administrative expenses because such amounts have
historically not been allocated to the Producing Properties or such amounts
would not be indicative of those expenses which would be incurred by MOXY.  The
statements include gross oil and gas revenue and direct operating and production
expenses, including production and ad valorem taxes, for the entire periods
presented.

    The unaudited statement of gross oil and gas revenues and direct operating
expenses for the three-month period ended March 31, 1997, in the opinion of
management, was prepared on a basis consistent with the audited statements of
gross oil and gas revenues and direct operating expenses and includes all
adjustments (which includes normal recurring adjustments) necessary to present
fairly the gross oil and gas revenues and direct operating and production
expenses for this interim period and may not be indicative of future revenues
and expenses.

2.  SUPPLEMENTAL INFORMATION ON OIL AND GAS RESERVES (UNAUDITED)

    There are numerous uncertainties inherent in estimating quantities of proved
reserves and in projecting the future rates of production and timing of
development expenditures.  The following reserve data represent estimates only
and should not be construed as the current market value of the properties or the
cost that would be incurred to obtain equivalent reserves.

    An analysis of the estimated changes in quantities of proved oil and natural
gas reserves of the Producing Properties for the year ended December 31, 1996
and for the period from the inception of the MOXY/MCN Program through December
31, 1995 is shown below.  Oil, including condensate and plant products, is
stated in thousands of barrels and natural gas is in millions of cubic feet.

between McMoRan Oil & Gas Co., a  Delaware corporation ("MOXY"), and Freeport-

("FRP").


                             W I T N E S S E T H:


     WHEREAS, FRP has agreed to purchase all of MCN's right, title and interest
in and to the MCN Program Assets pursuant to the MCN Purchase Agreement and
contemporaneously with the acquisition thereof to execute and deliver to MOXY
the MOXY/MCN Program Amendment;

     WHEREAS, MOXY and FRP desire to form the MOXY/FRP Exploration Program and
MOXY desires to acquire from FRP the MCN Producing Properties on the terms
hereinafter set forth;

     WHEREAS, FRP is unwilling to form the MOXY/FRP Exploration Program until
MOXY has the funding necessary to support its commitments thereunder and to
purchase the MCN Producing Properties;

     WHEREAS, MOXY intends to raise the funds necessary to participate in the
MOXY/FRP Exploration Program and to purchase the MCN Producing Properties
through the Rights Offering, and FRP has agreed to make the Standby Commitment
to ensure that MOXY receives its desired level of funding;

     WHEREAS, MOXY's ability to consummate the Rights Offering and thereby
participate in the MOXY/FRP Exploration Program and acquire the MCN Producing
Properties is subject to the approval of the Rights Offering, the Standby
Purchase Agreement and the related transactions by the MOXY Stockholders at the

     WHEREAS, terms not otherwise defined elsewhere herein have the meanings
ascribed to them in Article VII.

     NOW, THEREFORE, for and in consideration of the premises, and the
respective covenants, agreements, representations and warranties contained
herein, and for other good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, the parties hereto, intending to
be legally bound, hereby agree as follows:

                      MCN PROPERTIES AND MOXY/MCN PROGRAM
 

     1.1 MCN Purchase Agreement; MOXY/MCN Program Amendment. On July 10, 1997,
FRP, MCN and MOXY executed and delivered the MCN Purchase Agreement pursuant to
which FRP will, subject to the terms and conditions set forth therein, acquire
all of MCN's right, title and interest in and to the MCN Program Assets as soon
as possible after the date hereof. Contemporaneously with the consummation of
the transactions contemplated by the MCN Purchase Agreement, MOXY and FRP shall
execute and deliver the MOXY/MCN Program Amendment.

     1.2  MCN Producing Property Purchase; Loan Repayment.

          (a) Subject to the terms and conditions of this Agreement, at the
Closing (i) FRP agrees to sell and convey to MOXY, and MOXY agrees to purchase
from FRP, all of FRP's right, title and interest in the MCN Producing Properties
effective as of the Effective Time and (ii) MOXY agrees to repay all amounts
then outstanding under the Loan, including principal and accrued but unpaid
interest thereon to but excluding the Closing Date.

          (b) At the Closing, MOXY shall (i) deliver to FRP the estimated
Purchase Price described in Sections 1.2(c) and 1.2(d) below and (ii) repay all
amounts then outstanding under the Loan, including principal and accrued but
unpaid interest thereon to but excluding the Closing Date by, in each case, wire
transfer of immediately available funds to an account designated by FRP.  At the
Closing, FRP shall transfer to MOXY the MCN Producing Properties in accordance
with the provisions hereof and, except as provided in this Section 1.2, on the
same terms as such properties shall have been acquired by FRP from MCN.  Such
transfer shall be made pursuant to duly executed and acknowledged assignments
and such other documents as may be reasonably necessary in the opinion of
counsel to MOXY and FRP to convey the MCN Producing Properties to MOXY.  FRP
shall also execute and deliver such documents as may be reasonably necessary in
the opinion of counsel to MOXY and FRP to evidence the repayment of the Loan and
to release any lien or security interest created under the MOXY/MCN Program
securing MOXY's obligations under the Loan.

          (c) The purchase price payable by MOXY to FRP for the MCN Producing
Properties shall be $26.0 million, subject to adjustment as follows:  (i)
increased or decreased, as the case may be, by the difference between (A) the
development costs, lease operating expense and any other amount paid by FRP (or
for which payment credit is given in the MCN Purchase Agreement) attributable to
the MCN Producing Properties during the period from the Effective Time to the
Closing Date (the "Interim Period") and (B) the amount of any proceeds received
by FRP (or for which payment credit is given in the MCN Purchase Agreement)
attributable to the MCN Producing Properties during the Interim Period, in each
case calculated in the same manner provided for in Article VIII of the MCN
Purchase Agreement solely with respect to the MCN Producing Properties,  and
(ii) interest calculated on a daily basis on the net 


                                      I-2
<PAGE>
 
cash invested during the Interim Period by FRP with respect to the MCN Producing
Properties at an annual rate publicly announced by The Chase Manhattan Bank from
time to time as its base rate plus 2%. Such price, as so adjusted, is
hereinafter referred to as the "Purchase Price."

          (d) Prior to the Closing, FRP and MOXY shall agree in good faith on an
estimated Purchase Price, subject to being finalized within 120 days after the
Closing Date.  Within 120 days after the Closing Date, FRP and MOXY shall
attempt to agree upon a final accounting of the actual Purchase Price.  If FRP
and MOXY cannot reach mutual agreement on the final Purchase Price, then the
matter shall be resolved by submittal to Price Waterhouse LLP, whose decision
shall be binding upon the parties.  The costs incurred in retaining Price
Waterhouse LLP to resolve any difference in the final accounting shall be borne
equally by each of the parties.  The credits agreed upon by MOXY and FRP or
resolved by Price Waterhouse LLP shall be netted and the final settlement shall
be paid in cash as directed in writing by the receiving party.

          (e) After the closing of the transactions contemplated by the MCN
Purchase Agreement, MOXY shall assume and discharge all obligations and
liabilities, known and unknown, attributable to the ownership and operation of
the MCN Program Assets prior to the Effective Time and shall indemnify and hold
FRP harmless from and against any such obligations or liabilities to the extent
they have not been the subject of an adjustment to the Purchase Price.

     1.3  Adjustments.

          (a) Subject to the terms and conditions of this Agreement, MOXY and
FRP shall, effective immediately following the Closing, terminate the MOXY/MCN
Program and cause all of their right, title and interest in and to the leases
and other properties that are subject to the MOXY/MCN Program immediately prior
to the Closing (other than the MCN Producing Properties) to be made subject to
and included in the MOXY/FRP Exploration Program on the terms set forth in this
Section 1.3.

          (b) The leases and other properties to be included in the MOXY/FRP
Exploration Program pursuant to this Section 1.3 shall be so included with
retroactive effect to the Effective Time as if such properties and leases had
been subject to the MOXY/FRP Exploration Program since the Effective Time and
the interests in each such lease or other property shall be retroactively
adjusted between FRP and MOXY to reflect the relative interests of each in the
MOXY/FRP Exploration Program.  MOXY and FRP shall make appropriate
reimbursements of and adjustments to the costs incurred with respect to each
such lease and property and execute and deliver such documents as are necessary
in order to transfer an interest in each such lease or other property effective
as of the Effective Time in order to effectuate the foregoing adjustments.  The
adjustments required pursuant to this Section 1.3(b) shall be netted and a final
settlement shall be paid in cash as directed by the receiving party with
interest on the weighted average outstanding balance of such amount until the
date paid at an annual rate publicly announced by The Chase Manhattan Bank from
time to time as its base rate plus 2%.


                                      I-3

          (c) FRP and MOXY shall agree in good faith on the adjustments required
by this Section 1.3, subject to being finalized within 120 days after the
Closing Date.  Within 120 days after the Closing Date, FRP and MOXY shall
attempt to agree upon a final accounting of the actual adjustments.  If FRP and
MOXY cannot reach mutual agreement on the adjustments, then the matter shall be
resolved by submittal to Price Waterhouse LLP, whose decision shall be binding
upon the parties.  The costs incurred in retaining Price Waterhouse LLP to
resolve any difference in the final accounting or the adjustments shall be borne
equally by each of the parties.  The adjustments agreed upon by MOXY and FRP or
resolved by Price Waterhouse LLP shall be netted and a final settlement shall be
paid in cash as directed in writing by the receiving party.

          (d) If, for whatever reason, the Closing does not occur and this
Agreement is terminated in accordance with its terms, then the MOXY/MCN Program
shall continue in accordance with the terms set forth in the MOXY/MCN Program
Agreement, as amended by the MOXY/MCN Program Amendment.

     Each party hereby represents and warrants to the other party as to itself
that:



     3.1  Existence and Power.  Such party is duly organized, validly existing
and in good standing under the laws of its jurisdiction of organization, and has
all powers and all material governmental licenses, authorizations, consents and
approvals required to carry on its business as now conducted. Such party is duly
qualified to do business as a foreign corporation or partnership, as the case
may be, and is in good standing in each jurisdiction where the character of the
property owned or leased by it or the nature of its activities make such
qualification necessary, except for those jurisdictions where failure to be so
qualified would not, individually or in the aggregate, result in a Material
Adverse Effect.

     3.2  Authorization.  The execution, delivery and performance by such party
of this Agreement, the Transaction Documents to which it is a party and all
other documents, instruments and certificates executed and delivered by such
party in connection herewith or therewith, and the consummation by such party of

and, except for the approval by the MOXY Stockholders contemplated herein, have
been duly authorized by all necessary action on the part of such party. MOXY
represents and warrants to FRP that its board of directors has taken all actions
necessary to ensure that none of (a) the provisions of Section 203 of the

Restated Certificate of Incorporation or any other corporate documents or
agreements of MOXY in any way restricts or prohibits the consummation of the
transactions contemplated by this Agreement, including but not limited to FRP's

the FRP Purchase Option, and to render all such provisions inapplicable to such
acquisition and ownership. MOXY has amended its shareholder rights plan to
exempt FRP and its affiliates and associates from the shareholder rights plan.
MOXY represents and warrants to FRP that the affirmative vote of MOXY
Stockholders holding a majority of the outstanding shares of Common Stock

approve any of the transactions contemplated hereby and by the Transaction
Documents. FRP represents and warrants to MOXY that no vote of the unit holders
of FRP is required to approve the transactions contemplated hereby and by the
Transaction Documents. This Agreement and each of the Transaction Documents have
been, or when executed and delivered in accordance with the terms hereof and
their respective terms will be, duly and validly executed and delivered by such
party and each constitutes, or when executed and delivered will constitute, a
valid and binding agreement of such party, enforceable in accordance with its
terms, except as (a) enforceability may be limited by applicable bankruptcy,
insolvency, fraudulent transfer, moratorium or similar laws from time to time in
effect affecting creditors' rights generally and (b) the availability of
equitable remedies may be limited by equitable principles of general
applicability.

     3.3  Governmental Authorization.  The execution, delivery and performance
by such party of this Agreement, the Transaction Documents to which it is a
party and all other documents,

connection herewith or therewith, require no action by or in respect of, or
filing with, any governmental body, agency, official or authority other than

party of this Agreement, the Transaction Documents to which it is a party and
all other documents, instruments and certificates executed or to be executed and
delivered by such party in connection herewith or therewith, do not and will
not: (i) contravene or conflict with the partnership agreement or certificate of
incorporation or bylaws of such party, as the case may be; (ii) assuming
compliance with the matters referred to in Section 3.3, contravene or conflict
with or constitute a violation of any provision of any law, regulation,
judgment, injunction, order or decree binding upon or applicable to such party;

provision of any credit agreement, note, bond, mortgage, indenture, lease,

controlling Person's assets is or may be bound; (iv) result in the creation or
imposition of any lien on an asset; or (v) contravene or conflict with any

contract or other instrument binding upon such party or its subsidiaries as a
result of the execution, delivery and performance of this Agreement, any
Transaction Document or any other document, instrument or certificate to be
executed or delivered by such party in connection herewith or therewith or the
consummation of the transactions contemplated hereby or thereby, including
without limitation any agreement, contract or instrument requiring the consent
of lenders to such party or its subsidiaries or any Person controlling such
party, except for the approval of the MOXY Stockholders in the case of MOXY and
such other consents which will be obtained on or prior to the Closing Date or
which would not, individually or in the aggregate, result in a Material Adverse
Effect if not received by the Closing Date.

     3.6  SEC Documents.  Such party has made available to the other true 
and complete copies of each report, schedule, registration statement and
definitive proxy statement filed with the SEC since January 1, 1995 and prior to
the date of this Agreement, which are all the documents (other than preliminary
material) that it has been required to file with the SEC since January 1, 1995.
As of their respective dates, such documents filed by such party complied in all
material respects with the requirements of the Securities Act or the Exchange
Act, as the case may be, and the rules and regulations of the SEC thereunder and
none contained any untrue statement of a material fact or omitted to state a
material fact required to be stated therein or necessary to make the statements

The financial statements of such party contained in each such document complied
as to form in all material respects with the published rules of the SEC with
respect thereto, were prepared in accordance with generally accepted accounting
principles applied on a consistent basis during the periods involved (except as
may be indicated in notes thereto), or in the case of unaudited statements, as

applicable requirements of generally accepted accounting principles (subject, in
the case of unaudited statements, to normal, recurring adjustments) the

operations and cash flows of the party for the periods presented therein. MOXY
represents and warrants that the Proxy Statement and the Registration Statement
will comply as to form in all material respects with the relevant provisions of
the Exchange Act or the Securities Act, as the case may be, and the rules and
regulations thereunder and will not contain any untrue statement of a material
fact or omit to state a material fact required to be stated therein or necessary
to make the statements therein, in light of the circumstances under which they
were made, not misleading.

     3.7  Information Supplied.  None of the information supplied or to be
supplied by such party for inclusion or incorporation by reference in the
Registration Statement will, at the time the Registration Statement becomes
effective under the Securities Act, contain any untrue statement of a material
fact or omit to state any material fact required to be stated therein or
necessary to make the statements therein, in light of the circumstances under
which they were made, not misleading, and none of the information supplied or to
be supplied by such party and included or incorporated by reference in the Proxy
Statement will, at the date mailed to the MOXY Stockholders or at the time of
the MOXY Stockholders' Meeting, contain any untrue statement of a material fact
or omit to state any material fact required to be stated therein or necessary to
make the statements therein, in light of the circumstances under which they are
made, not misleading. If, at any time prior to the Closing Date any event with
respect to which either party, or with respect to any information supplied for
inclusion in the Proxy Statement or Registration Statement, shall occur that is
required to be described in an amendment of, or supplement to, the Proxy
Statement or Registration Statement, such event shall be so described and such
amendment or supplement shall be promptly filed with the SEC.

     3.8  MCN Purchase Agreement.  In order to induce FRP to enter into and
perform its obligations under this Agreement and the MCN Purchase Agreement,
MOXY hereby makes the following additional representations and warranties to
FRP. MOXY represents and warrants to FRP that: (a) there are no violations of

or that might materially hinder or impede the operation of the MCN Properties
and, to the best of MOXY's knowledge, there is no such proceeding threatened
against MCN; (c) MOXY has not alienated any of its interests in the leases and

                             ADDITIONAL AGREEMENTS
 

     4.1  Preparation of the Proxy Statement and Registration Statement.  As 
promptly as practicable after the date hereof, MOXY shall file
with the SEC the Proxy Statement and Registration Statement.  MOXY shall use its
best efforts to have the Registration Statement declared effective as promptly
as practicable after such filing.  MOXY shall use its best efforts to cause the
Proxy Statement to be mailed to the MOXY Stockholders at the earliest
practicable date.  If the Rights Offering and the Standby Purchase Agreement are

good faith and upon the advice of counsel.

     4.3  Access to Information.  Upon reasonable notice, MOXY and FRP shall
each afford to the officers, employees, agents and other representatives of the

between MOXY and FRP (the "Confidentiality Agreement") shall remain in force and
apply to the information furnished thereunder or hereunder and any other
activities contemplated thereby.

     4.4  Regulatory and Other Approvals.

          (a) Each party hereto shall cooperate and use its best efforts to
promptly prepare and file all necessary documentation, to effect all necessary
applications, notices, petitions, filings and other documents, and use all
commercially reasonable efforts to obtain (and will cooperate with each other in
obtaining) any consent, acquiescence, authorization, order or approval of, or
any exemption or non-opposition by, any governmental entity required to be
obtained or made by either party in connection with this Agreement or the other
Transaction Documents or the taking of any action required thereby or by this
Agreement.

          (b) Prior to the effective date of the Registration Statement, MOXY
shall have taken all action necessary to permit it to issue the Rights and the
shares of Common Stock required to be issued pursuant to the Rights Offering and
to have the Rights and such shares approved for listing on the Nasdaq National
Market.

     4.5  Certain Actions.

            Subject to the terms and conditions of this Agreement, each party
will use its best efforts to take, or cause to be taken, all actions and to do,
or cause to be done, all things necessary, proper and advisable under applicable
laws and regulations to consummate the

transactions contemplated by this Agreement. In connection with and without
limiting the foregoing, MOXY and its Board of Directors shall use their best
efforts to (a) take all reasonable actions necessary so that no state takeover
statute or similar statute or regulation is or becomes applicable to this
Agreement or any of the transactions contemplated hereby, and (b) if any state
takeover statute or similar statute or regulation becomes applicable to any of
the foregoing, take all action necessary so that the transactions contemplated
by this Agreement and the Transaction Documents may be consummated as promptly
as practicable on the terms contemplated hereby and otherwise to minimize, to
the reasonable satisfaction of FRP, the effect of such statute or regulation on
the transactions contemplated hereby.

     4.6  Fairness Opinion Not Withdrawn.  It shall be a condition of MOXY's
obligation to mail the Proxy Statement and to hold the MOXY Stockholders'
Meeting that the fairness opinion of Donaldson, Lufkin & Jenrette Securities
Corporation dated the date hereof shall not have been withdrawn.

Re:  STANDBY PURCHASE COMMITMENT

McMoRan Oil & Gas Co.
1615 Poydras Street
New Orleans, LA 70112

Attention:  Mr. Richard C. Adkerson, Co-Chairman and Chief Executive Officer
            Mr. C. Howard Murrish, President and Chief Operating Officer

Gentlemen:

  We understand that McMoRan Oil & Gas Co. ("MOXY") intends to distribute 
to holders of record of shares of its Common Stock, par value $0.01 per share 
("COMMON STOCK"), transferable subscription rights (the "RIGHTS") to subscribe 
for and purchase additional shares of Common Stock as follows (the "RIGHTS 
OFFERING"):  The exercise price for each Right will be $3.50 per share (the 
"SUBSCRIPTION PRICE").  Each holder of record of shares of Common Stock on the 
record date for the distribution of Rights will receive approximately 2 Rights 
for every share of Common Stock held.  Each Right will represent the right to 
purchase one share of Common Stock (the "BASIC SUBSCRIPTION PRIVILEGE").  Each 
holder of Rights (each a "HOLDER") who elects to exercise in full the Basic 
Subscription Privilege may also subscribe to purchase at the Subscription 
Price additional shares of Common Stock available as a result of unexercised 
Rights, if any (the "OVERSUBSCRIPTION PRIVILEGE").  28,571,429 shares of 
Common Stock will be issuable upon exercise of all of the Rights.  The Rights 
will be transferable and will expire 30 days after issuance or on such later 
date as may be agreed between MOXY and FRP (such initial date or any such 
later date, the "EXPIRATION DATE").  The Rights and the shares of Common Stock 
issuable upon exercise thereof will be listed on the Nasdaq National Market 
("NASDAQ").

  Based on the structure of the Rights Offering described above and in 
consideration of the mutual representations, warranties and agreements 
contained herein, the parties hereto hereby agree as follows:

        1.  STANDBY COMMITMENT.  Upon the terms and subject to the conditions 
set forth herein, MOXY agrees to sell to FRP, and FRP agrees to purchase from 
MOXY (the "STANDBY COMMITMENT"), at the Subscription Price, all the shares of 
Common Stock issuable upon exercise of the Rights if and to the extent that 
such shares of Common Stock are not purchased by Holders pursuant to the 
exercise of the Rights, including the Oversubscription Privilege (such 
unpurchased shares being referred to as the "EXCESS SHARES").  Subject to 
Section 3 below, 


                                     II-1
<PAGE>
 
payment of the aggregate Subscription Price for the Excess Shares shall be made
on the third business day following the Expiration Date (the "Closing Date"),
against delivery to FRP of certificates evidencing the shares of Common Stock
purchased by it, in immediately available funds by wire transfer to an account
of MOXY designated by MOXY by notice to FRP no later than one business day prior
to the Closing Date.

        2.  FRP PURCHASE OPTION. (a) Promptly on or after the Expiration Date 
and after all prorations and adjustments contemplated by the terms of the 
Rights Offering shall have been effected (but in no event later than the date 
one business day after the Expiration Date), MOXY shall deliver, or cause the 
Subscription Agent (as defined in the Registration Statement) to deliver, a 
written notice (the "STANDBY PURCHASE NOTICE") to FRP setting forth  the 
aggregate number of Rights properly exercised by Holders pursuant to the terms 
of the Rights Offering;  the aggregate number of Excess Shares to be purchased 
by FRP pursuant to its Standby Commitment (the "STANDBY PURCHASE AMOUNT");  
the aggregate Subscription Price therefor; and  the calculation, including 
reasonable details thereof, of the maximum number of Additional Shares, if 
any, available for purchase by FRP pursuant to the FRP Purchase Option as 
provided in subsection (b) below.

        (b)  MOXY hereby grants FRP an option (the "FRP PURCHASE OPTION") to 
purchase, at the Subscription Price, up to such number of shares of Common 
Stock, if any, (the "ADDITIONAL SHARES") as shall result in FRP's owning 30% 
of the aggregate outstanding shares of Common Stock immediately after giving 
effect to such purchase and the Standby Purchase Amount.  FRP may exercise the 
FRP Purchase Option, in whole or in part, within one business day after 
receiving the Standby Purchase Notice, by delivering a written notice to MOXY 
setting forth the number of Additional Shares it wishes to purchase pursuant 
to the FRP Purchase Option.  Such exercise of the FRP Purchase Option shall 
not thereafter be revocable by FRP.  The purchase of the Additional Shares 
pursuant to the FRP Purchase Option shall take place on the Closing Date in 
the same manner as the purchase of the Excess Shares pursuant to the Standby 
Commitment as set forth in Section 1 above.

        3.  STANDBY COMMITMENT FEE.  As compensation to FRP for its Standby 
Commitment and its obligations under the Master Agreement (including but not

to be taken, all actions and to do, or cause to be done, all things necessary or
desirable under applicable laws and regulations to consummate the transactions
contemplated by this letter agreement. MOXY and FRP shall cooperate with one
another in determining whether any action by or in respect of, or filing with,
any governmental body, agency, official, or authority is required, or any
actions, consents, approvals or waivers are required to be obtained from parties
to any material contracts, in connection with the consummation of the

consent of FRP.

        (c) MOXY will promptly deliver to FRP, without charge, such number of 
copies of the Registration Statement as FRP shall reasonably request.

        (d)  MOXY will use the proceeds from the Rights Offering and from the 
issuance of the Additional Shares, if any, solely as set forth under the 
heading "Use of Proceeds" in the Registration Statement.

        7.  CONDITIONS OF FRP'S OBLIGATIONS. The obligation of FRP to purchase
the Excess Shares pursuant to the Standby Commitment shall be subject to the
satisfaction (or waiver by FRP in its sole discretion) of the following
conditions precedent:

        (a)   All the conditions precedent set forth in Sections 5.1 and 5.2 of 
the Master Agreement shall have been satisfied.

        (b)  MOXY shall have executed and delivered to FRP a Participation 
Agreement in connection with the MOXY/FRP Exploration Program substantially in 
the form of Exhibit A to the Master Agreement; and

        (c) MOXY shall have executed and delivered to FRP a Stockholder 
Agreement substantially in the form of Exhibit D to the Master Agreement.

        8.  INDEMNIFICATION; SURVIVAL. (a) MOXY agrees to indemnify and hold
harmless FRP, its officers, directors, agents and affiliates and each person, if
any, who controls FRP within the meaning of Section 15 of the Securities Act or
Section 20 of the Exchange Act, from 


                                     II-4
<PAGE>
 
and against any and all losses, claims, damages, liabilities and judgments
(collectively, "LOSSES") (i) arising out of any misrepresentation or breach of
warranty, covenant or agreement made or to be performed by MOXY pursuant to this
letter agreement or (ii) caused by any untrue statement or alleged untrue
statement of a material fact contained in the Registration Statement, any
preliminary prospectus or any other document, including but not limited to the
proxy statement, filed by MOXY with the Commission in connection with the
transactions contemplated hereby and by the Registration Statement
(collectively, the "SEC DOCUMENTS"), or caused by any omission or alleged
omission to state therein a material fact required to be stated therein or
necessary to make the statements therein not misleading, except insofar as such
Losses are caused by any such untrue statement or omission or alleged untrue
statement or omission based upon information relating to FRP furnished in
writing to MOXY by or on behalf of FRP expressly for use therein.

        (b)  FRP agrees to indemnify and hold harmless MOXY, its officers, 
directors, agents and affiliates and each person controlling MOXY within the 
meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act 
to the same extent as the foregoing indemnity from MOXY to FRP, but only with 
respect to (i) any misrepresentation or breach of warranty, covenant or 
agreement made or to be performed by FRP pursuant to this letter agreement or 
(ii) information relating to FRP furnished in writing to MOXY by or on behalf 
of FRP expressly for use in the SEC Documents. 

        (c) If the foregoing indemnification is unavailable to an indemnified 
party in respect of any Losses, then each indemnifying party, in lieu of 
indemnifying such indemnified party, shall contribute to the amount paid or 
payable by such indemnified party as a result of such Losses  in such 
proportion as is appropriate to reflect the relative benefits received by MOXY 
on the one hand and FRP on the other hand from the Rights Offering or  if such 
allocation is not permitted by applicable law, in such proportion as is 
appropriate to reflect not only such relative benefits but also the relative 
fault of MOXY and FRP in connection with the statements or omissions which 
resulted in such Losses as well as any other relevant equitable 
considerations.  The relative benefits received by MOXY and FRP shall be 
deemed to be in the same proportion as the total net proceeds from the Rights 
Offering (before deducting expenses) received by MOXY shall bear to the 
Standby Commitment Fee received by FRP hereunder.  The relative fault of MOXY 
and FRP shall be determined by reference to, among other things, whether the 
untrue or alleged untrue statement of a material fact or the omission to state 
a material fact relates to information supplied by MOXY or FRP and the 
parties' relative intent, knowledge, access to information and opportunity to 
correct or prevent such statement or omission.  MOXY and FRP agree that it 
would not be just and equitable if contribution pursuant to this subsection 
were determined by pro rata allocation or by any other method of allocation 
which does not take into account the equitable considerations referred to 
herein.  Notwithstanding the foregoing, FRP shall not be required to 
contribute any amount in excess of an amount equal to the Standby Commitment 
Fee. 

        (d)  The respective representations, warranties, indemnities, 
contribution agreements and other statements of each of the parties hereto 
shall remain operative and in full force and effect, 


                                     II-5
<PAGE>
 
and will survive delivery of and payment for the Excess Shares and the
Additional Shares, if any, regardless of any investigation, or statement as to
the results thereof, made by or on behalf of MOXY or FRP, the delivery of and
payment for the Excess Shares and the Additional Shares, if any, hereunder and
the termination of this letter agreement.

        9.  TERMINATION.  This letter agreement shall automatically terminate 
if the Master Agreement is terminated in accordance with its terms.  

        10.  NOTICES.  All notices and other communications to be given 
pursuant hereto shall be in writing and be effective upon receipt and may be 
given by overnight courier or hand delivery and shall be given at the

the Board of Directors shall consist of such number of Directors as may be 
fixed from time to time by a majority of the Directors then in office, giving

Beneficial Owner of at least 10% but less than a majority of the outstanding 
Common Stock, FRP shall be entitled 


                                     III-3
<PAGE>
 
to designate by written notice to MOXY from time to time that number of
Directors (each an "FRP Designee") equal to the nearest whole number obtained by
multiplying the FRP Percentage by the number of Directors that are to serve on
the Board of Directors after giving effect to the election of the FRP Designees
and the Independent Directors required pursuant to Section 2(i). Upon receipt of
a written request of FRP to exercise its rights under this Section 2(b), MOXY
shall create that number of vacancies on the Board of Directors as determined in
accordance with the preceding sentence either by (i) an increase in the number
of Directors in accordance with the terms of the Certificate of Incorporation
and the By-laws, (ii) Director resignations or (iii) a combination thereof.

            (c)  Election of FRP Designees.  The Board of Directors shall 
elect FRP Designees as soon as practicable following receipt of a notice from 
FRP in accordance with Section 2(b) to fill the vacancies on the Board of 
Directors created in accordance with the last sentence of Section 2(b), to 
serve from the time when they are elected until their successors are elected 
and qualified.  Each of the FRP Designees shall be elected to a different 
class of the Board of Directors as provided by the Certificate of 
Incorporation and the By-laws, unless the Board of Directors elects more than 
three FRP Designees, in which case the FRP Designees shall be elected to 
different classes as proportionally as practicable.

            (d)  Nomination and Election of Subsequent FRP Designees.  The 
Board of Directors (or any committee of the Board of Directors that nominates 
Directors) shall, in connection with each meeting of stockholders of MOXY at 
which the term of any FRP Designee expires (if FRP shall then have the right 
to designate Directors), nominate for election as a Director, in accordance 
with MOXY's procedures for nomination of Directors as provided for in its By-
laws, one or more FRP Designees designated in accordance with Section 2(b) to 
stand for election for the next succeeding term, and shall vote all management 
proxies in favor of such nominees, except for such proxies that specifically 
indicate to the contrary.  MOXY shall recommend that its stockholders vote in 
favor of such nominees, and shall use reasonable efforts to solicit from its 
stockholders proxies voted in favor of such nominees.

            (e)  FRP Designee Replacements.  If any FRP Designee shall 
decline or be unable to serve for any reason, or if such FRP Designee resigns 
or is removed (other than in the case of a resignation pursuant to Section 
2(d) hereof), the Board of Directors shall promptly upon the request of FRP 
nominate or elect, as the case may be, a new FRP Designee to replace such 
resigned or removed FRP Designee.

            (f)  Voting.  As long as FRP shall be the Beneficial Owner of at 
least 10% of the Common Stock, at each meeting of stockholders of MOXY, FRP 
shall vote the shares of Common Stock held by FRP for the nominees recommended 
by the Board of Directors.

            (g)  Resignation of FRP Designees.  At such time as FRP shall 
become the Beneficial Owner of less than 10% of the outstanding Common Stock, 
FRP shall, at the request 


                                     III-4
<PAGE>
 
of MOXY, use its best efforts to cause any FRP Designees then serving as
Directors to resign from the Board of Directors.

            (h)  Information Regarding FRP Designees.  FRP shall use its best 
efforts to cause each FRP Designee to promptly provide to MOXY, as MOXY may 
from time to time reasonably request, information regarding such FRP Designee 
for inclusion in any form, report, schedules, registration statement, 
definitive proxy statement or other documents required to be filed by MOXY 
with the SEC.

            (i) Independent Committee.  Within six months after the date 
hereof, MOXY shall create two vacancies on the Board of Directors either by 
(i) an increase in the number of Directors in accordance with the terms of the 
Certificate of Incorporation and the By-laws, (ii) Director resignations or 
(iii) a combination thereof and shall designate, and the Board of Directors 
shall elect at least two Independent Directors to the Board of Directors.  The 
Board of Directors shall, in connection with each meeting of stockholders of 
MOXY at which the term of any Independent Director expires, select one or more 
individuals who would qualify for membership on the Independent Committee to 
stand for election for the next succeeding term.  If any Independent Director 
shall decline or be unable to serve for any reason, or if such Independent 
Director resigns, the Board of Directors shall promptly nominate or elect, as 
the case may be, a new Independent Director to replace such resigned 
Independent Director.  The Independent Directors shall constitute the 
Independent Committee of the Board of Directors (the "Independent Committee"). 
The affirmative vote of a majority of the Independent Directors shall be the 
act of the Independent Committee.

        3.  Approval by Independent Committee.  

            (a)   Actions by MOXY.  After the Independent Committee has been 
elected in accordance with Section 2(i), for as long as FRP shall be the 
Beneficial Owner of 10% or more of the outstanding Common Stock, subject to 
the Certificate of Incorporation and applicable law, MOXY shall not take any 
of the following actions without the approval of the Independent Committee:

                  (i)     repurchase any outstanding shares of Common Stock;

                  (ii)    enter into any Material Transaction; 

                  (iii)   enter into any "Rule 13e-3 transaction" within the 
            meaning of Rule 13e-3 under the Exchange Act;

                  (iv)    amend, modify or grant any waiver under the 
            Stockholder Rights Plan, the Participation Agreement or this 
            Agreement; or

                  (v)     in connection with any merger or business combination 
            involving MOXY and a third party, treat FRP and the other holders 
            of Common Stock on other than equivalent terms.

            (b)     Actions by FRP.  For as long as FRP shall be the Beneficial 
Owner of more than 10% of the outstanding Common Stock, except as specifically 
approved by the Independent Committee, neither FRP nor any of FRP's Affiliates 
shall, directly or indirectly, (i) by purchase or otherwise, acquire, agree to 
acquire or offer to acquire beneficial ownership of any additional shares of 
Common Stock (other than through open-market purchases that do not constitute 
a "Rule 13e-3 transaction" within the meaning of Rule 13e-3 under the Exchange 
Act), or (ii) enter into, propose to enter into, solicit or support any merger 
or business combination or similar transaction involving FRP or any of its 
Affiliates and MOXY.  In considering whether any of the foregoing transactions 
would be in the best interests of and fair to the holders of Common Stock 
other than FRP and its Affiliates, the Independent Committee shall consider 
the value of MOXY as a whole without any reduction related to the size of 
FRP's ownership interest in MOXY.

        4. Registration Rights. 

            (a)   Demand Registration.  (i)  FRP may at any time and from time 
to time make a written request for registration under the Securities Act of 
not less than 10% of the outstanding Common Stock (a "Demand Registration"); 
provided that MOXY shall not be obligated  to effect more than one Demand 
Registration in any 12-month period or more than an aggregate of three Demand 
Registrations pursuant to this Section 4(a).  Such request will specify the 
number of shares of Registrable Securities proposed to be sold and will also 
specify the intended method of disposition thereof.  A registration will not 
count as a Demand Registration until it has become effective; provided, 
however, that a Demand Registration that is either withdrawn or not declared 
effective at FRP's request shall count as a Demand Registration unless FRP 
also bears all of the expenses specified in Section 4(e) hereof (as being 
payable by MOXY) with respect to such Demand Registration.

            (ii) If FRP so elects, the offering of such Registrable 
Securities pursuant to such Demand Registration shall be in the form of an 
underwritten offering.  FRP shall select the managing Underwriters and any 
additional investment bankers and managers to be used in connection with the 
offering; provided that such managing Underwriters and additional investment 
bankers must be reasonably satisfactory to MOXY.

        (b)  Piggyback Registration.  If MOXY proposes to file a registration
statement under the Securities Act with respect to an offering of Common Stock
(i) for MOXY's own account (other than a registration statement on Form S-4 or
S-8 (or any substitute form that may be adopted by the SEC)) or (ii) for the
account of any of its holders of Common Stock (other than FRP), then MOXY shall
give written notice of such proposed filing to FRP as soon as 


                                     III-6
<PAGE>
 
practicable (but in no event less than 10 days before the anticipated filing
date), and such notice shall offer FRP the opportunity to register such number
of shares of Registrable Securities as FRP may request on the same terms and
conditions as MOXY's or such holder's Common Stock (a "Piggyback Registration").

        (c)  Reduction of Offering.  Notwithstanding anything contained 
herein, if the managing Underwriter of an offering described in Section 4(b) 
delivers a written opinion to MOXY that the size of the offering that FRP, 
MOXY and any other Persons whose securities are included in such offering 
intend to make are such that the success of the offering would be materially 
and adversely affected, then the amount of Registrable Securities to be 
offered for the account of FRP and any other Person shall be reduced to the 
extent necessary to reduce the total amount of common stock to be included in 
such offering to the amount recommended by such managing Underwriter; provided 
that if Common Stock is being offered for the account of Persons other than 
MOXY, then the proportion by which the amount of such Registrable Securities 
intended to be offered for the account of FRP is reduced shall not exceed the 
proportion by which the amount of such securities intended to be offered for 
the account of such other Persons is reduced.

        (d)  Filings; Information.  Whenever FRP requests that any 
Registrable Securities be registered pursuant to Section 4(a) hereof, MOXY 
will use its reasonable efforts to effect the registration of such Registrable 
Securities as promptly as is practicable, and in connection with any such 
request:

              (i)  MOXY will as expeditiously as possible prepare and file with
        the SEC a registration statement on any form for which MOXY then
        qualifies and which counsel for MOXY shall deem appropriate and
        available for the sale of the Registrable Securities to be registered
        thereunder in accordance with the intended method of distribution
        thereof, and use its reasonable efforts to cause such filed registration
        statement to become and remain effective for a period of not less than
        120 days (or such shorter period which will terminate when all
        Registrable Securities covered by such registration statement have been
        sold); provided that if MOXY shall furnish to FRP a certificate signed
        by MOXY's Chief Executive Officer stating that in his good faith
        judgment it would be detrimental or otherwise disadvantageous to MOXY or
        its shareholders for such a registration statement to be filed as
        expeditiously as possible, MOXY shall have a period of not more than 120
        days within which to file such registration statement measured from the
        date of MOXY's receipt of FRP's request for registration in accordance
        with Section 4(a) hereof.

              (ii) MOXY will, if requested, prior to filing such registration
        statement or any amendment or supplement thereto, furnish to FRP and
        each applicable managing Underwriter, if any, copies thereof, and
        thereafter furnish to FRP and 


                                     III-7
<PAGE>
 
        each such Underwriter, if any, such number of copies of such
        registration statement, amendment and supplement thereto (in each case
        including all exhibits thereto and documents incorporated by reference
        therein) and the prospectus included in such registration statement
        (including each preliminary prospectus) as FRP or each such Underwriter
        may reasonably request in order to facilitate the sale of the
        Registrable Securities.

              (iii)  After the filing of the registration statement, MOXY will
        promptly notify FRP of any stop order issued or, to MOXY's knowledge,
        threatened to be issued by the SEC and take all reasonable actions
        required to prevent the entry of such stop order or to remove it if
        entered.

              (iv) MOXY will endeavor to qualify the Registrable Securities for
        offer and sale under such other securities or blue sky laws of such
        jurisdictions in the United States as FRP reasonably requests; provided
        that MOXY will not be required to (A) qualify generally to do business
        in any jurisdiction where it would not otherwise be required to qualify
        but for this subparagraph 4(d)(iv), (B) subject itself to taxation in
        any such jurisdiction or (C) consent to general service of process in
        any such jurisdiction.

              (v)  MOXY will as promptly as is practicable notify FRP, at any
        time when a prospectus relating to the sale of the Registrable
        Securities is required by law to be delivered in connection with sales
        by an Underwriter or dealer, of the occurrence of any event requiring
        the preparation of a supplement or amendment to such prospectus so that,
        as thereafter delivered to the purchasers of such Registrable
        Securities, such prospectus will not contain an untrue statement of a
        material fact or omit to state any material fact required to be stated
        therein or necessary to make the statements therein, in the light of the
        circumstances under which they were made, not misleading and promptly
        make available to FRP and to the Underwriters any such supplement or
        amendment. FRP agrees that, upon receipt of any notice from MOXY of the
        occurrence of any event of the kind described in the preceding sentence,
        FRP will forthwith discontinue the offer and sale of Registrable
        Securities pursuant to the registration statement covering such
        Registrable Securities until receipt by FRP and the Underwriters of the
        copies of such supplemented or amended prospectus and, if so directed by
        MOXY, FRP will deliver to MOXY all copies, other than permanent file
        copies then in FRP's possession, of the most recent prospectus covering
        such Registrable Securities at the time of receipt of such notice. In
        the event MOXY shall give such notice, MOXY shall extend the period
        during which such registration statement shall be maintained effective
        as provided in Section 4(d)(i) by the number of days during the period
        from and including the date of the giving of such notice to the date


                                     III-8
<PAGE>
 
        when MOXY shall make available to FRP such supplemented or amended
        prospectus.

              (vi) MOXY will enter into customary agreements (including an
        underwriting agreement in customary form) and take such other actions as
        are reasonably required in order to expedite or facilitate the sale of
        such Registrable Securities.

              (vii) MOXY will furnish to FRP and to each Underwriter a signed
        counterpart, addressed to FRP or such Underwriter, of an opinion or
        opinions of counsel to MOXY and a comfort letter or comfort letters from
        MOXY's independent public accountants, each in customary form and
        covering such matters of the type customarily covered by opinions or
        comfort letters, as the case may be, as FRP or the managing Underwriter
        reasonably requests.

              (viii) MOXY will make generally available to its security holders,
        as soon as reasonably practicable, an earnings statement covering a
        period of 12 months, beginning within three months after the effective
        date of the registration statement, which earnings statement shall
        satisfy the provisions of Section 11(a) of the Securities Act and the
        rules and regulations of the SEC thereunder.

              (ix) MOXY will use its reasonable efforts to cause all such
        Registrable Securities to be listed on each securities exchange or over-
        the-counter market on which the Common Stock is then listed.

        MOXY may require FRP promptly to furnish in writing to MOXY such 
information regarding FRP, the plan of distribution of the Registrable 
Securities and other information as MOXY may from time to time reasonably 
request or as may be legally required in connection with such registration.

        (e)  Registration Expenses.  In connection with any Demand
Registration or any Piggyback Registration, MOXY shall pay the following
expenses incurred in connection with such registration: (i) filing fees with the
SEC, (ii) fees and expenses of compliance with securities or blue sky laws
(including reasonable fees and disbursements of counsel in connection with blue
sky qualifications of the Registrable Securities), (iii) printing expenses, (iv)
fees and expenses incurred in connection with the listing of the Registrable
Securities, (v) fees and expenses of counsel and independent certified public
accountants for MOXY and (vi) the reasonable fees and expenses of any additional
experts retained by MOXY in connection with such registration. FRP shall pay any
underwriting fees, discounts or commissions attributable to the sale of
Registrable Securities and any out-of-pocket expenses of FRP.


                                     III-9
<PAGE>
 
        (f)  Indemnification by MOXY.  MOXY agrees to indemnify and hold 
harmless FRP, its officers and directors, and each Person, if any, who 
controls FRP within the meaning of either Section 15 of the Securities Act or 
Section 20 of the Exchange Act from and against any and all losses, claims, 
damages and liabilities caused by any untrue statement or alleged untrue 
statement of a material fact contained in any registration statement or 
prospectus relating to the Registrable Securities (as amended or supplemented 
if MOXY shall have furnished any amendments or supplements thereto) or any 
preliminary prospectus, or caused by any omission or alleged omission to state 
therein a material fact required to be stated therein or necessary to make the 
statements therein not misleading, except insofar as such losses, claims, 
damages or liabilities are caused by any such untrue statement or omission or 
alleged untrue statement or omission based upon information, relating to FRP 
or the plan of distribution furnished in writing to MOXY by or on behalf of 
FRP expressly for use therein; provided that the foregoing indemnity agreement 
with respect to any preliminary prospectus shall not inure to the benefit of 
FRP if a copy of the most current prospectus at the time of the delivery of 
the Registrable Securities was not provided to purchaser and such current 
prospectus would have cured the defect giving rise to such loss, claim, damage 
or liability.  MOXY also agrees to indemnify any Underwriters of the 
Registrable Securities, their officers and directors and each person who 
controls such Underwriters on substantially the same basis as that of the 
indemnification of FRP provided in this subparagraph.

        (g)  Indemnification by FRP.  FRP agrees to indemnify and hold 
harmless MOXY, its officers and directors, and each Person, if any, who 
controls MOXY within the meaning of either Section 15 of the Securities Act or 
Section 20 of the Exchange Act to the same extent as the foregoing indemnity 
from MOXY to FRP, but only with reference to information relating to FRP or 
the plan of distribution furnished in writing by or on behalf of FRP expressly 
for use in any registration statement or prospectus relating to the 
Registrable Securities, or any amendment or supplement thereto, or any 
preliminary prospectus.  FRP also agrees to indemnify and hold harmless any 
Underwriters of the Registrable Securities, their officers and directors and 
each person who controls such Underwriters on substantially the same basis as 
that of the indemnification of MOXY provided in this subparagraph.

        (h)  Conduct of Indemnification Proceedings.  In case any 
proceeding (including any governmental investigation) shall be instituted 
involving any Person in respect of which indemnity may be sought pursuant to 
Section 4(f) or Section 4(g), such Person (the "Indemnified Party") shall 
promptly notify the Person against whom such indemnity may be sought (the 
"Indemnifying Party") in writing and the Indemnifying Party shall have the 
right to assume the defense of such proceeding and retain counsel reasonably 
satisfactory to such Indemnified Party to represent such Indemnified Party and 
any others the Indemnifying Party may designate in such proceeding and shall 
pay the fees and disbursements of such counsel related to such proceeding.  In 
any such proceeding, any Indemnified Party shall have the right to retain its 
own counsel, but the fees and expenses of such counsel shall be at the expense 
of such Indemnified Party unless (i) the Indemnifying Party and the 
Indemnified Party shall have 


                                    III-10
<PAGE>
 
mutually agreed to the retention of such counsel or (ii) the named parties to
any such proceeding (including any impleaded parties) include both the
Indemnified Party and the Indemnifying Party and representation of both parties
by the same counsel would be inappropriate due to actual or potential differing
interests between them. It is understood that the Indemnifying Party shall not,
in connection with any proceeding or related proceedings in the same
jurisdiction, be liable for the fees and expenses of more than one separate firm
of attorneys (in addition to any local counsel) at any time for all such
Indemnified Parties, and that all such fees and expenses shall be reimbursed as
they are incurred. In the case of any such separate firm for the Indemnified
Parties, such firm shall be designated in writing by the Indemnified Parties.
The Indemnifying Party shall not be liable for any settlement of any proceeding
effected without its written consent, but if settled with such consent, or if
there be a final judgment for the plaintiff, the Indemnifying Party shall
indemnify and hold harmless such Indemnified Parties from and against any loss
or liability (to the extent stated above) by reason of such settlement or
judgment.

        (i)  Contribution.  If the indemnification provided for in this 
Agreement is unavailable to an Indemnified Party in respect of any losses, 
claims, damages or liabilities referred to herein, then each such Indemnifying 
Party, in lieu of indemnifying such Indemnified Party, shall contribute to the 
amount paid or payable by such Indemnified Party as a result of such losses, 
claims, damages or liabilities (i) in such proportion as is appropriate to 
reflect the relative benefits received by MOXY, FRP and the Underwriters from 
the offering of the securities, or (ii) if the allocation provided by clause 
(i) above is not permitted by applicable law, in such proportion as is 
appropriate to reflect not only the relative benefits referred to in clause 
(i) but also the relative fault of MOXY, FRP and the Underwriters in 
connection with the statements or omissions that resulted in such losses, 
claims, damages or liabilities, as well as any other relevant equitable 
considerations.  The relative benefits received by MOXY, FRP and the 
Underwriters shall be deemed to be in the same respective proportions as the 
total proceeds from the offering (net of underwriting discounts and 
commissions but before deducting expenses) received by each of MOXY and FRP 
and the total underwriting discounts and commissions received by the 
Underwriters, in each case as set forth in the table on the cover of the 
prospectus, bear to the aggregate public offering price of the securities.  
The relative fault of MOXY, FRP and the Underwriters shall be determined by 
reference to, among other things, whether the untrue or alleged untrue 
statement of a material fact or the omission or alleged omission to state a 
material fact relates to information supplied by such party and the parties' 
relative intent, knowledge, access to information and opportunity to correct 
or prevent such statement or omission.

        MOXY and FRP agree that it would not be just and equitable if
contribution pursuant to this Section 4(i) were determined by pro rata
allocation (even if the Underwriters were treated as one entity for such
purpose) or by any other method of allocation that does not take account of the
equitable considerations referred to in the immediately preceding paragraph. The
amount paid or payable by an Indemnified Party as a result of the losses,
claims, damages or liabilities referred to in the immediately preceding
paragraph shall be deemed to include, 


                                    III-11
<PAGE>
 
subject to the limitations set forth above, any legal or other expenses
reasonably incurred by such Indemnified Party in connection with investigating
or defending any such action or claim. Notwithstanding the provisions of this
Section 4(i), no Underwriter shall be required to contribute any amount in
excess of the amount by which the total price at which the Securities
underwritten by it and distributed to the public were offered to the public
exceeds the amount of any damages which such Underwriter has otherwise been
required to pay by reason of such untrue or alleged untrue statement or omission
or alleged omission, and FRP shall not be required to contribute any amount in
excess of the amount by which the net proceeds of the offering (before deducting
expenses) received by FRP exceeds the amount of any damages which FRP has
otherwise been required to pay by reason of such untrue or alleged untrue
statement or omission or alleged omission. No person guilty of fraudulent
misrepresentation (within the meaning of Section 11(f) of the Securities Act)
shall be entitled to contribution from any Person who was not guilty of such
fraudulent misrepresentation.

        (j) Participation in Underwritten Registrations.  No Person may
participate in any underwritten registered offering contemplated hereunder
unless such Person (a) agrees to sell its securities on the basis provided in
any underwriting arrangements approved by the Persons entitled hereunder to
approve such arrangements and (b) completes and executes all questionnaires,
powers of attorney, indemnities, underwriting agreements and other documents
reasonably required under the terms of such underwriting arrangements and these
Registration Rights.

        (k) Rule 144.  MOXY covenants that it will file any reports required
to be filed by it under the Securities Act and the Exchange Act and that it will
take such further action as FRP may reasonably request to the extent required
from time to time to enable FRP to sell Registrable Securities without
registration under the Securities Act within the limitation of the exemptions
provided by Rule 144 under the Securities Act, as such Rule may be amended from
time to time, or any similar rule or regulation hereafter adopted by the SEC.
Upon the request of FRP, MOXY will deliver to FRP a written statement as to
whether it has complied with such reporting requirements.

        (l)  Holdback Agreements.  FRP agrees not to offer, sell, contract to
sell or otherwise dispose of any Registrable Securities, or any securities
convertible into or exchangeable or exercisable for such securities, during the
14 days prior to, and during the 180-day period beginning on, the effective date
of such registration statement other than (i) the Registrable Securities to be
sold pursuant to such registration statement, and (ii) any shares of Common
Stock sold upon the exercise of an option or warrant or the conversion of a
security outstanding at such date.

        5. Miscellaneous.  

              (a)   Notices.  Any notice or communication required or 
permitted hereunder shall be in writing and either delivered personally or 
sent by certified or registered mail, postage prepaid, and shall be deemed to 
be given, dated and received when so delivered personally or, if mailed, three 
business days after the date of mailing to the following address or to such 
other address or addresses as such person may subsequently designate by notice 
given hereunder.

              If to MOXY, to:

                   McMoRan Oil & Gas Co.
                   1615 Poydras Street          
                   New Orleans, Louisiana 70112 
                   Attention:  Richard C. Adkerson, Co-Chairman of the Board  
                               and Chief Executive Officer 

              If to FRP, to

                   Freeport-McMoRan Resource Partners, Limited Partnership
                   1615 Poydras Street
                   New Orleans, Louisiana 70112
                   Attention:  Rene L. Latiolais, President and Chief 
                               Executive Officer

Any party from time to time may change its address, facsimile number or other 
information for the purpose of notices to that party by giving notice 
specifying such change to the other party hereto.

        (b)   Termination.  The respective covenants and agreements of MOXY and
FRP contained in this Agreement will continue in full force and effect until the
earliest to occur of any of the following: (i) the mutual written agreement of
MOXY and FRP or (ii) at such time as FRP shall no longer be the Beneficial Owner
of 10% or more of the outstanding Common Stock. Notwithstanding the termination
of this Agreement, nothing contained herein shall relieve any party hereto from
liability for breach of any of its covenants or agreements contained in this
Agreement.

        (c)   Waivers and Amendments; Noncontractual Remedies; Specific 
Performance.  This Agreement may be amended, superseded, canceled, 
renewed or extended, and the terms hereof may be waived, only by a written 
instrument signed by or on behalf of each party hereto or, in the case of a 
waiver, by the party waiving compliance. No delay on the part of any party in 
exercising a right, power or privilege hereunder shall operate as a waiver 
thereof, nor shall any waiver on the part of any party of any such right, 
power or privilege, nor any single or partial exercise of any such right, 
power or privilege, preclude a further exercise thereof or 


                                    III-13
<PAGE>
 
the exercise of any other such right, power or privilege. MOXY and FRP agree
that any breach by either of them of any provision of this Agreement would
irreparably injure the other party and that money damages would be an inadequate
remedy therefor. Accordingly, each of MOXY and FRP agrees that the other party
shall be entitled to one or more injunctions enjoining any such breach and
requiring specific performance of this Agreement and consents to the entry
thereof.

        (d)  Severability.  If any provision of this Agreement or the
applicability of any such provision to a person or circumstances shall be
determined by any court of competent jurisdiction to be invalid or unenforceable
to any extent, the remainder of this Agreement or the application of such
provision to persons or circumstances other than those for which it is so
determined to be invalid and unenforceable, shall not be affected thereby, and
each provision of this Agreement shall be valid and shall be enforced to the
fullest extent permitted by law. To the extent permitted by applicable law, each
party hereto hereby waives any provision or provisions of law which would
otherwise render any provision of this Agreement invalid, illegal or
unenforceable in any respect.

        (e) Counterparts.  This Agreement may be executed by the parties
hereto in separate counterparts and when so executed shall constitute one
Agreement, notwithstanding that all parties are not signatories to the same
counterpart.

        (f) Governing Law.  This Agreement shall be governed and construed in
accordance with the laws of the State of Delaware applicable to agreements made
and to be performed entirely within such state, without regard to the conflict
of law rules of such state.

        (g) Successors and Assigns. This Agreement shall be binding upon and
inure to the benefit of and be enforceable by the successors and assigns of the
parties hereto; provided that the registration rights granted by MOXY in Section
4 may only be transferred to transferees who are the holder of 5% or more of the
Registrable Securities.

                              Purpose; Operations

        2.1 Purpose. This Agreement has been entered into to provide 
Participant a means of acquiring, exploring and developing oil and gas 
Prospects in the Program Area, including but not limited to the acquisition of 
the Initial Leasehold Inventory, during the Program Term.
 
        On _____________, Participant acquired all of the interests of MCNIC Oil
& Gas Properties, Inc. and affiliates ("MCN") in the McMoRan Participation &
Exploration Program Agreement and McMoRan and Participant entered into an
amendment thereto dated the same date (as amended, the "Prior Program"). McMoRan
and Participant thereafter continued the Prior Program on an interim basis until
the date hereof.

        The parties hereto hereby contribute to the Program all of their rights 
respecting each of the properties and assets of the Prior Program excluding 
only those properties and assets associated with the properties which are 
located in an Excluded Area ("Excluded Properties") and the loan (the "Loan") 
paid the date hereof due Participant by McMoRan under said Prior Program.  The 
Leasehold Interests owned by McMoRan and Participant under the Prior Program, 
excluding those which are Excluded Properties, shall be the Initial Leasehold 
Inventory hereunder.  The costs incurred by McMoRan and Participant with 
respect to those Leasehold Interests which are included in the Initial 
Leasehold Inventory and as to which Participant acquired its interest from MCN 
shall be deemed to have an initial cost as of April 1, 1997 of $8,333,333, 
$5,000,000 of which was paid by Participant and $3,333,333 of which was paid 
by McMoRan, which amount shall be deemed to have been expended from the 
Exploration Fund.  All other expenditures under the Prior Program by McMoRan 
and Participant together, other than with respect to the Excluded Areas and 
the Loan, shall likewise be treated as having been expended from the 
Exploration Fund.

        2.2 McMoRan Efforts. McMoRan agrees to devote a substantial portion of 
its oil and gas exploration effort to the operation and management of the 
Program, which shall include all 


                                     IV-3
<PAGE>
 
prospects, except those in the Excluded Areas, acquired and to be acquired by
McMoRan during the Program Term within the Program Area, including but not
limited to the Initial Leasehold Inventory. McMoRan will at all times have a
staff adequate in number, experience and competence to perform its obligations
hereunder and accomplish the purposes of the Exploration Program.

        Operator. McMoRan shall be the overall manager of the Program.


                                     III.
                      Sharing of Exploration Expenditures
                          and Interest of the Parties

        3.1 Sharing of Exploration Expenditures. Except as otherwise provided 
in this Agreement, Exploration Expenditures shall be shared as follows:

                              ParticipantMcMoRan
                                    60%40%

        If more than one Exploratory Well is drilled on a particular Onshore
Prospect, Exploration Expenditures in connection with the drilling of any second
and subsequent Exploratory Well on such particular onshore Prospect shall not be
shared in the percentages set forth in this Paragraph 3.1 but shall be shared in
the percentages set forth in Paragraph 3.2 hereof; provided, however, if the
first Exploratory Well in such particular Onshore Prospect fails to reach
objective depth because it encounters impenetrable substances, heaving shale,
domal material, salt, excessive salt water flow or other formation or conditions
or develops mechanical difficulty which would render further drilling
impractical and McMoRan elects to drill a substitute for such well, the cost
involved in the drilling of such substitute well shall be shared in the
percentages set forth in this Paragraph 3.1 in the same manner as if such
substitute well were the first Exploratory Well on the particular Onshore
Prospect involved.

        3.2 Ownership Interests. Except as otherwise provided in this Agreement,
the ownership of all Leasehold Interest and other properties and production
acquired by the Program shall be shared as follows:

                              ParticipantMcMoRan
                                    50%50%


                                      IV.
                           Exploration Expenditures

        4.1 Exploration Expenditures. Subject to the limitations provided in
this Agreement, McMoRan shall be entitled to expend monies for Exploration
Expenditures of the Program on behalf 


                                     IV-4
<PAGE>
 
of itself and Participant without the prior approval of Participant. The term
"Exploration Expenditures" means all actual charges allocable to each Prospect
in accordance with generally accepted industry standards, which charges are
incurred by the Program prior to (i) the completion of the first Exploratory
Well drilled by the Program on an Onshore Prospect that is completed as a well
capable of production in Paying Quantities or (ii) the plugging, or the
temporary abandonment if not plugged, of the first two Exploratory Wells drilled
by the Program on an Offshore Prospect, as applicable, and such other costs
applicable to exploration activities in the Program Area as are otherwise
provided for in this Agreement, which charges, among others, shall include the
following:

        (a)  The cost of acquisition of all Leasehold Interests in the Program 
Area, including but not limited to the Initial Leasehold Inventory and any 
Leasehold Interest Costs paid by McMoRan to third party program operators in 
connection therewith;

        (b)  The cost of any geological, geophysical or other scientific, 
exploration or engineering work, services or data on the Prospect;

        (c)  The cost of copies of all seismic records, geological and 
geophysical maps and other exploration data and information furnished to 
Participant;

        (d)  Rental and other lease maintenance payments on the Leasehold 
Interests;

        (e)  All necessary independent legal expenses and costs of title 
searches and title investigation whether or not Leasehold Interests are 
acquired, together with the costs of copies of title opinions and other title 
reports furnished to Participant;

        (f)  The cost of drilling Exploratory Wells in a Prospect, including 
the cost of plugging and abandoning or capping same, if no completion attempt 
is made;

        (g)  Any other expenditures properly chargeable as Exploration 
Expenditures under this Agreement, or as may be specified in the accounting 
procedure attached to the applicable Program Operating Agreement and which are 
attributable to exploration activities, but excluding all overhead provided 
for in such Program Operating Agreement until such time as the Exploration 
Fund has been fully committed;

        (h)  Notwithstanding the foregoing, the cost of completing an 
Exploratory Well shall not be considered an Exploration Expenditure; and

        (i)  In addition to the foregoing, McMoRan shall be entitled to charge 
as Exploration Expenditures those expenditures that McMoRan incurs annually 
for salaries of employees, including but not limited to costs of benefits 
programs related thereto, cost of retained consultants, including but not 
limited to its Technical Consultants, office rent, office supplies, insurance 
and other general  and administrative costs that McMoRan incurs in the conduct 
of its activities, including but not limited to costs allocated to MOXY from 
FM Services Company or its Affiliates, less a reasonable 


                                     IV-5
<PAGE>
 
portion of such costs that McMoRan allocates to the Excluded Areas. Prior to
committing to a material increase in the aggregate costs contemplated by this
subparagraph (i) McMoRan shall confer with Participant and in good faith
consider any comments or suggestions that Participant may offer in regard to
such contemplated material change.

        The term Exploration Expenditures shall also include any of the 
foregoing costs incurred by the Program in attempting to locate or acquire 
Leasehold Interests in Prospects for the Program in the Program Area whether 
or not the Program owns or acquires Leasehold Interest in such area or 
subsequently designates a Prospect under Paragraph 8.1 for such area.

        Except as may be expressly provided to the contrary in this Agreement, 
all Exploration Expenditures shall be invoiced and accounted for in accordance 
with the accounting procedure attached to the Program Operating Agreement, 
including the period of time set forth for joint interest auditing and 
adjustment.

        McMoRan shall further be entitled to reimbursement as an Exploration 
Expenditure or as a proper expenditure under the applicable Program Operating 
Agreement, as appropriate, from Participant for its share of reasonable 
inventories of pipe and equipment (it being the intention of the parties to 
keep such inventories at a minimum level consistent with the needs of the 
Program).

        McMoRan shall not have an obligation to spend a particular portion of 
the Program Fund during any Program Year but rather McMoRan shall commit 
Exploration Expenditures as the occasion arises to secure Prospects which 
McMoRan deems would be appropriate for the Exploration Program, subject to the 
provisions of Paragraph 6.1 hereof.

        McMoRan agrees to make available its entire geological and geophysical 
data base for use in operations under the Program at no cost to the 
Participant, except to the extent setforth in the immediately following 
sentence.  The amounts expended in acquiring seismic data from Western 
Geophysical pursuant to the Licensing Agreement between McMoRan and Western 
Geophysical dated November 20, 1996 shall constitute proper charges to 
Exploration Expenditures, notwithstanding the  fact that some of the costs 
incurred pursuant to such agreement were incurred prior to the beginning of 
the Program Term, except to the extent that any of such seismic data so 
acquired relates to Excluded Areas.

        Participant agrees to bear its proportionate part of all Exploration 
Expenditures of the Program, subject to the limitations hereinafter set forth 
under Article VI.

                                      V.
                      Acquisition of Leasehold Interests

        5.1  Acquisition of Leasehold Interest. On behalf of the Program and 
subject to the limitations and guidelines herein set forth, McMoRan shall 
evaluate and acquire Leasehold Interests in the Program Area during the 
Program Term which it believes to be potentially productive of oil or gas.


                                     IV-6
<PAGE>
 
        5.2  Excluded Areas. McMoRan and Participant agree that the following 
areas ("Excluded Areas") shall not be subject to the terms of this Agreement 
unless any such area, or portion thereof, has been recommended for inclusion 
herein by McMoRan in writing and Participant has concurred in writing in that 
recommendation:

        (a)  Any Leasehold Interest or prospect lying outside the Program Area;

        (b)  Any Leasehold Interest or Prospect which at the time of acquisition
contains proven reserves unless (i) the then proven reserves do not constitute a
material consideration in the acquisition, and (ii) the primary objective of the
acquisition is to explore for oil and gas other than the then proven reserves;

        (c)  Those areas identified on attached Exhibit III; and

        (d)  Any Leasehold Interest or prospect acquired through merger, 
acquisition, corporate reorganization or consolidation with or purchase of 
substantially all of the assets of an individual, a corporation or a 
partnership, provided that the primary purpose of such merger, acquisition, 
reorganization, consolidation or purchase is not to acquire a specific 
Prospect or Leasehold Interest which otherwise would be subject to this 
Agreement; provided, however, if in such an acquisition McMoRan acquires an 
inventory of exploratory prospects not associated with any proven production 
acquired in such acquisition, McMoRan shall meet with Participant and, in good 
faith, attempt to have the exploratory prospects transferred to the 
Exploration Program 

        5.3  Obligation. Subject to the limitations otherwise provided in this 
Agreement, Participant agrees to participate for its proportionate share of 
Exploration Expenditures as to all Leasehold Interest acquired or committed to 
by McMoRan in the Program Area during the Program Term.  Without limiting or 
altering the effect of the AMI provisions of Article XIII hereof, from and 
after the end of the Program Term, McMoRan shall not be obligated to search 
for and offer to Participant any interest in Leasehold Interests within the 
Program Area.   

                                      VI.
                               Exploration Fund

        6.1  General. The Program shall have a budget of $200,000,000 for 
Exploration Expenditures to be incurred or committed during the Program Term 
(the "Exploration Fund").  Notwithstanding that the Exploration Fund is for 
the entire Program Term, unless McMoRan and Participant agree otherwise in 
writing, McMoRan will schedule its activities so that Exploration Expenditures 
are not likely to exceed on a cumulative basis one hundred fifty percent 
(150%) of $40,000,000 per twelve months period times the number of twelve 
months periods that have elapsed since the Program Term commenced.      

        6.2  Limitations on McMoRan's Authority to Commit Exploration Fund. In 
addition to the other limitations imposed upon McMoRan's authority to commit 
Participant hereunder, once the actual and committed Exploration Expenditures 
reach the budgeted total, it is understood and agreed 


                                     IV-7
<PAGE>
 
that McMoRan (i) will not undertake any additional drilling commitments on
behalf of the Exploration Program, and (ii) will not acquire any additional
Leasehold Interests on behalf of the Exploration Program. Additionally, McMoRan
shall not make any commitment on behalf of the Program for the drilling of any
well which is anticipated to commence more than six (6) months after the end of
the Program Term.

        6.3  Budget Meetings and Reports.

        (a)  On a quarterly basis, McMoRan shall hold a meeting in McMoRan's 
offices with Participant to discuss the contemplated activities of the Program 
for the following period.  In such  meetings, McMoRan shall advise Participant 
of the amounts of the Exploration Fund which have been committed to Prospects 
on which an Exploratory Well has not yet commenced.  Such advise shall include 
the name of the Prospect, the amount of the Exploration Fund anticipated to be 
spent thereon and the anticipated commencement date of the Exploratory Well to 
be drilled thereon.  On a monthly basis, McMoRan shall provide Participant 
with an accounting of the Exploration Expenditures of the prior month and 
Program Term to date reconciling prior billings and advance billings with 
expenditures.  McMoRan will promptly advise Participant in writing when 
McMoRan reasonably believes that actual and committed Exploration Expenditures 
of the Program equal the Exploration Fund and will furnish reasonable data 
supporting such conclusion.  In addition to the foregoing, McMoRan will 
furnish Participant on request and at Participant's expense any other data or 
information needed by Participant to comply with any governmental laws, rules 
and regulations, including those promulgated by the Securities and Exchange 
Commission.


                                     VII.
                      Scientific Studies and Information

        7.1  Scientific Studies and Information. During the Program Term, 
McMoRan shall conduct geological, geophysical, engineering and other 
scientific studies with respect to the acquisition and/or exploration of 
Leasehold Interest ("Scientific Studies") in the Program Area and the cost 
thereof shall be Exploration Expenditures.

        It is agreed that any seismic records, and other exploration data (not 
including any interpretation thereof by McMoRan or its Technical Consultants) 
that may be acquired by McMoRan under the terms of this Agreement shall become 
and remain the joint property of McMoRan and Participant.  If McMoRan 
designates a Prospect under Paragraph 8.1 hereof affecting such acquired data, 
McMoRan shall at such time furnish copies of all such data, upon written 
request of Participant, including geological and geophysical maps, to 
Participant unless McMoRan is prohibited from furnishing a copy or disclosing 
it to Participant under the agreement by which McMoRan acquired such data.  
Except as otherwise provided in this Agreement, Participant shall be permitted 
full access to such data in McMoRan's offices unless prohibited from doing so 
under the agreement by which McMoRan acquires such data.  McMoRan shall not be 
precluded from 


                                     IV-8
<PAGE>
 
entering into data exchange agreements which McMoRan in good faith believes will
benefit the Program and all data acquired pursuant to any such exchange
agreement shall be the joint property of McMoRan and Participant. During and
after the Program Term, McMoRan shall have the exclusive right to sell any such
data which McMoRan in good faith believes no longer must be kept confidential
for the purposes of the Program and the proceeds of such sale shall be shared by
the Participant and McMoRan on the same basis as the said parties own such data.
At the end of the Program Term, McMoRan shall identify seismic records and other
pertinent acquired data (not including any interpretation thereof by McMoRan or
its Technical Consultants) as to which Prospects have not been designated during
the Program Term and McMoRan shall, upon written request by Participant, provide
it copies of all or any part of such data, unless prohibited from doing so under
the agreement by which McMoRan acquired such data. Notwithstanding anything
herein to the contrary, Participant shall not have or acquire any property
interest in any interpretations by McMoRan or its Technical Consultants of any
seismic or other exploration data unless and until a Prospect based thereon has
been designated by McMoRan hereunder.


                                     VIII.
                                   Prospects

        8.1  Prospects. From time to time McMoRan will obtain information upon 
which it can determine and define a particular portion of the Program Area 
with sufficient specificity as to be identified as a Prospect.  The term 
"Prospect" means a contiguous area which can reasonably be interpreted from 
geological and/or geophysical data as encompassing a geological structure, 
stratigraphic trap or other common geologic feature which makes its treatment 
as a single Prospect for oil and gas production purposes reasonable and some 
portion of which is considered prospective for commercial oil or gas 
production and is designated as such pursuant to this Article VIII.  Based on 
such information, McMoRan shall from time to time designate an area as a 
Prospect of the Program.  The size and configuration of a Prospect, as well as 
all details incident thereto, shall be determined by McMoRan.  During the 
Program Term, McMoRan alone shall determine the time when an area is 
designated as a Prospect, whether or not Leasehold Interests have previously 
been acquired therein.  After the Program Term and in accordance with 
Paragraph 8.2 hereof, McMoRan or Participant shall have the right to designate 
a Prospect which includes Leasehold Interests theretofore acquired through the 
Program.  Without the prior consent of Participant, McMoRan shall not commit 
to the Program any Prospects which (1) McMoRan's economic analysis indicates 
will not have at least a before taxes rate of return of twenty-five (25) 
percent, or (2) the water depth for the first expected platform location is 
greater than 1,000 feet.

        At the time that McMoRan designates a Prospect it shall furnish to 
Participant a land plat showing the approximate outline of the Prospect and 
the proposed AMI therefor.  Subject to Paragraph 5.2, McMoRan shall as soon as 
possible thereafter, upon written request of Participant, furnish Participant 
(to the extent not previously furnished) with all pertinent data then 
available with respect to the evaluation of such Prospect for oil or gas 
development excluding only such data as McMoRan is prohibited from disclosing 
by reason of confidentiality agreements with third parties respecting such 
data.  Such data shall include a land and geophysical or geological report on 
such Prospect, including with respect to the drillsite for the first 
Exploratory Well proposed to be drilled 


                                     IV-9
<PAGE>
 
thereon, a land plat, farmin, farmout and other trade agreements, copies of
leases, drilling title opinions, assignments, unit designation agreements,
operating agreements and other documents necessary for Participant to maintain
adequate records relative to such Prospect and operations thereon, together with
such of the following, as and when available, which are applicable to each such
Prospect:

        (a)  An itemized list of all Exploration Expenditures charged to such 
Prospect;

        (b)  An itemized estimate of probable additional costs which may have 
to be incurred in connection with such Prospect;

        (c)  Any other information in McMoRan's possession relevant to an 
evaluation of such Prospect, including geological data, including but not 
limited to cross-sections, maps, key logs, and geophysical data, including 
copies of proprietary reprocessed data, sepias of lines; and

        (d)  A description of the primary geologic objective and prospective 
zone(s) for which the Prospect was acquired.

        At the time each such Prospect is designated, McMoRan will separately 
allocate to it all Exploration Expenditures theretofore incurred and properly 
attributable to such Prospect, including but not limited to those expenditures 
made pursuant to Paragraph 4.1 above.

        8.2  Designation of Prospects After Program Term. To the extent any 
Leasehold Interests acquired by the Program are not included in Prospects 
designated by McMoRan on or prior to the end of the Program Term, then after 
such date McMoRan or Participant or their respective successors in interest 
shall have the right to propose a Prospect at the time that it proposes an 
Exploratory Well thereon.  The geographic limits of such Prospect so 
designated shall meet the criteria set forth in Paragraph 8.1 and the AMI 
therefor shall be subject to the provisions of Article XIII hereof.


                                      IX.
                         Drilling of Exploratory Wells

        9.1  During Program Term. During the Program Term, at the same time as 
McMoRan designates a Prospect under Paragraph 8.1 above or thereafter when it 
commits the Exploration Fund to the drilling of an Exploratory Well thereon or 
as soon as possible after McMoRan has received notice from a third party joint 
interest owner that it proposes the drilling of a well thereon, McMoRan shall 
provide to Participant (if not previously furnished and requested in writing 
by Participant) the following information:

        (a)  An AFE for such well both as a dry hole and as a completed well;


                                     IV-10
<PAGE>
 
        (b)  A land plat depicting the Prospect, the proposed AMI for such 
Prospect and the Program's Leasehold Interests within the AMI for such 
prospect;

        (c)  A schedule of the Program's Leasehold Interests in the Prospect 
AMI;

        (d)  Maps depicting McMoRan's geological and geophysical interpretations
of the Prospect;

        (e)  McMoRan's economic analysis of the Prospect's potential and timing 
and estimated costs to develop, including description of facilities to be 
used, if then known;

        (f)  Information as to whether any other third party joint interest 
owner has elected to join or not to join in the drilling of such well;

        (g)  The surface location, proposed bottom hole location, proposed 
depth and well prognosis including casing program, mud program and logging 
program for such well (to the extent available in those cases where a third 
party is the operator of the well) and any other information in McMoRan's 
possession relevant to an evaluation of such well; and

        (h)  Any acreage or cash contribution pledged in support of the 
proposed operation.

        Beginning with the permitting process for any Exploratory Well drilled 
hereunder, and continuing through the drilling and completion, temporary 
abandonment or plugging and abandonment for such well, McMoRan shall provide 
the following information if requested in writing by Participant (to the 
extent available to McMoRan and not previously furnished):

        (a)  name of well, name of Prospect, and identification number;

        (b)  drilling permits, plugging and abandonment permits and permission 
to produce;

        (c)  all daily drilling reports, State completion reports, well
completion schematic diagram, stimulation reports and workover reports;

        (d)  all core analyses, fluid analyses, PVT. analyses, water sample 
analyses;

        (e)  all pressure survey, DST reports, and pressure buildup or drawdown 
data;

        all well logs.  

        9.2  After Program Term. After the Program Term, McMoRan or Participant 
shall have the right to propose the drilling of an Exploratory Well on any 
Prospect within which an Exploratory Well could be drilled consistent with the 
definition of "Exploratory Well" set out herein.  The terms and provisions of 
the applicable Program Operating Agreement shall govern any such proposal.

                                      X.
                      Farmout or Participation Agreements

        10.1  Participation Agreements. During the Program Term, if in the 
process of evaluation of a Prospect the data and information lead McMoRan to 
the good faith determination that because of the large expenditures required, 
the extraordinary risk involved or other facts deemed relevant by McMoRan, an 
outside venturer should be obtained in such Prospect, McMoRan shall have the 
right to undertake to negotiate an agreement with a third party to join in the 
drilling of the Exploratory Well on the Prospect and thereby acquire a portion 
of the Exploration Program's interest in such Prospect; provided, however, 
that if any such agreement would reduce the interest of the Exploration 
Program by more than fifty percent (50%), McMoRan must obtain the prior 
approval of Participant.  McMoRan shall give notice to Participant of its 
intention to negotiate an agreement with an outside venturer which would 
reduce the interest of the Exploration Program by more than fifty percent 
(50%), stating the time within which the circumstances require an expression 
of approval or disapproval by the Participant.  Failure of Participant to 
disapprove the proposed negotiation within the stated period of time may be 
deemed by McMoRan to be approval by Participant.  Any agreement with an 
outside venturer shall be on the basis of the outside venturer paying and 
bearing not less than the proportionate part of all drilling costs and 
expenses of the Exploratory Well attributable to the undivided interest 
transferred to such outside venturer, and the interest in the Prospect 
transferred to or earned by such outside venturer shall reduce the respective 
interests of McMoRan and Participant proportionately.  Any promotion or other 
consideration received by McMoRan incident to such agreement with an outside 
venturer shall be held for the benefit of the Exploration Program and the 
Participant shall be entitled to participate therein in proportion to its 
interest in the Prospect.

        10.2  Farmout Agreements. During the Program Term McMoRan shall have the
right to enter into farmout agreements with unrelated third parties on such
terms as it deems appropriate respecting Leasehold Interests or portions thereof
which are not anticipated to be drilled or committed to be drilled by the
Exploration Program during the Program Term; provided, however, McMoRan shall
keep Participant advised as to any such farmout proposals or plans and shall
honor the request of Participant that its interest in such Leasehold Interest or
Prospect not be farmed out if Participant advises McMoRan within ten (10) days,
or forty-eight (48) hours if a drilling rig is on location with stand-by rig
charges accumulating, of McMoRan's notice of intention to farmout that it will
participate as to its ownership interest in the drilling of the anticipated
farmout well.

        McMoRan shall not farmout any of Participant's Interest in a Prospect on
which the Program has a producing well without the prior consent of Participant.

        10.3  Trade Agreements. During the Program Term, in connection with the 
drilling of an Exploratory Well on a Prospect, McMoRan shall have complete 
authority to enter into unit agreements, acreage swap agreements, bottom hole 
and dry hole contribution agreements and any similar agreements with unrelated 
third parties.  The cost or proceeds of any of the forgoing agreements shall 
be credited or charged to the Participants (1) in the proportion that it 
participated in the drilling of the affected Exploratory Well, or (2) if the 
costs relate to the payment by the 


                                     IV-12
<PAGE>
 
Exploratory Program of a dry hole or bottom hole contribution to a third party,
in the proportion that Participant bears Exploration Expenditures hereunder, and
any interest in leases or oil or gas thus acquired by exchange shall constitute
Leasehold Interests subject hereto and be owned by McMoRan and Participant in
proportion to their ownership interest in such Prospect.

                                      XI.
                                    Burdens

        11.1  Burdens. The Leasehold Interests to be acquired by the Program 
shall be subject to and McMoRan and Participant each shall bear its 
proportionate part of all third party overriding royalties and other burdens 
on Leasehold Interest (including subsequently acquired Leasehold Interests in 
the Prospect AMI) which McMoRan contracts for incidental to the acquisition or 
evaluation of such Leasehold Interests.  Participant acknowledges that McMoRan 
has heretofore entered into a retainer agreement with a Technical Consultant 
and may enter into similar agreements with others during the Program Term.  
Without the consent of Participant, McMoRan agrees not to subject any 
Leasehold Interest to overriding royalty burdens to its Technical Consultants 
which exceed the amounts deliverable to its current Technical Consultant, CLK 
Company, L.L.C.(CLK),under their existing agreement as described in the letter 
to Participant dated the date hereof.  McMoRan has provided Participant with a 
copy of its current consulting agreement with CLK  and Participant agrees that 
it will bear its proportionate part of the overriding royalties to which CLK 
is entitled pursuant to the terms of said consulting agreement as to any 
Leasehold Interest acquired hereunder as well as to any Leasehold Interest 
that Participant may acquire pursuant to an AMI agreement subject hereto.


                                     XII.
                              Operating Agreement

        12.1  Operating Agreement. Except as otherwise provided in this 
Agreement, all operations on each Prospect will be carried out in accordance 
with the provisions of the Program Operating Agreement, Offshore or Onshore as 
applicable, with charges and credits to the join account to be made in 
accordance therewith, including all overhead as to the drilling of Development 
Wells.  In the event of conflict between the terms of the Program Operating 
Agreement and the terms of this Agreement, this Agreement shall control.  A 
particular Leasehold Interest or Prospect may be subject to a different form 
of operating agreement (third party) with one or more third parties not 
related to McMoRan, which operating agreement (third party) shall apply and 
control at the time it becomes effective in the event of conflict therewith 
and the Program Operating Agreement.  In the event of conflict between such 
operating agreement (third party)  and this Agreement (other than the Program 
Operating Agreement), this Agreement shall control as between McMoRan and 
Participant.

                            Area of Mutual Interest

        13.1  Third Party Area of Mutual Interest Agreements. McMoRan may be 
obligated to enter into third party AMI agreements in connection with the 
acquisition of additional Prospects for the Program.  Participant agrees to be 
bound by the provisions of such AMI agreements. 

        13.2  Program Area of Mutual Interest Agreement. At the time a Prospect 
is identified by McMoRan pursuant to Paragraph 8.1 hereof, there shall be 
created an Area of Mutual Interest among McMoRan and Participant.  The lands 
within such Area of Mutual Interest shall include the involved Prospect and 
shall be fixed and determined in the following manner:

        (a)   McMoRan shall submit to Participant a plat delineating the area 
which it determines on a sound geological basis should be considered as the 
area which, even though outside the boundaries of the Prospect, should be 
considered an area of mutual interest in connection with the Prospect.

        (b)   In the event that Participant does not accept the proposed area of
mutual interest, consultation shall be had between McMoRan and Participant in an
effort to fix and determine the area to constitute the area of mutual interest.

        (c)   If McMoRan and Participant are able to agree on such area, the 
area agreed upon shall constitute the Area of Mutual Interest, or if agreement 
cannot be reached, the area of the Leasehold Interests as to a Prospect all of 
which is under Federal leasing jurisdiction, or as to any other Prospect the 
area within one-half (1/2) mile surrounding the outer perimeter of the 
Prospect, shall constitute the Area of Mutual Interest; provided however, any 
such AMI shall not include any portion of an Excluded Area.     

        The AMI shall be effective so long as any Leasehold Interest in such AMI
is owned by any of the parties or is subject to this Agreement, but in no event
longer than the earlier of (i) December 31, 2006 or (ii) one (1) year after the
plugging and abandoning of an Exploratory Well thereon unless another
Exploratory Well has been commenced thereon or McMoRan and Participant have
agreed to install a drilling and production platform on such Prospect within
such one (1) year period.

        Any acquisition of Leasehold Interests within such AMI after the 
establishment thereof by McMoRan or Participant shall be made available to be 
shared by McMoRan and Participant.  Subject to the rights of any third party 
under third party AMI agreements as described in Paragraph 13.1, the other 
party shall have the option to participate in any such acquisition in the same 
proportion as such party's then interest in such Prospect, which option is to 
be exercised in the following manner: the acquiring party shall notify each of 
the other parties of such acquisition, furnish a copy thereof and such title 
information as the acquiring party has, stating the cost of such acquisition 
and/or obligations that must be assumed in connection therewith.  The other 
parties shall have a period of fifteen (15) days with respect to the interests 
not related to a drilling well, and forty-eight (48) hours (or such lesser 
period as required by the circumstances and stated in the notice) with respect 
to interests related to a drilling well after receipt of such notice within 
which to elect and notify the acquiring party whether or not such party 
desires to participate in such acquisition.  Failure to respond shall be 
deemed an election on the part of such party not to participate in such 
acquisition.


                                     IV-14
<PAGE>
 
Upon election and payment to the acquiring party of such other party's share of
the cost of such acquisition and assumption of its share of such obligations,
such other party shall be entitled to an assignment of such party's interest in
such acquisition. The foregoing provision of this paragraph shall not apply nor
shall they alter Participant's obligation to purchase its proportionate part of
any Leasehold Interests acquired by McMoRan hereunder in those cases where the
costs of acquiring such interests are Exploration Expenditures.

        In the event any party does not elect to participate in an interest 
tendered to it under this Paragraph 13.2 the participating parties may, within 
twenty-four (24) hours after notice thereof, elect to take their proportionate 
shares of the non-participating party's interest.  Time periods expressed in 
this Paragraph 13.2 are inclusive of Saturdays, Sundays and legal holidays.

        The provisions of this Paragraph 13.2 shall not be applicable to
acquisitions by any party hereto of an interest acquired through merger,
corporate reorganization or consolidation with or purchase of all or
substantially all of the assets of a corporation, an individual or a
partnership; provided, however, that the primary purpose of such merger,
corporate reorganization, consolidation or purchase is not to acquire Leasehold
Interests in a specific Prospect which otherwise would be subject to this
Agreement.


                                     XIV.
                            Ownership of Production

        14.1  Ownership of Production. All the oil, gas and casinghead gas 
produced for the account of the Leasehold Interests from any well shall be 
owned by McMoRan and Participant severally, in proportion to the respective 
interests of each therein as set forth in Paragraph 3.2. above, except as 
otherwise provided in this Agreement, and subject to the right, if any, that 
others may have under the terms of this Agreement or any operating agreement 
relating to such well.  Anything to the contrary herein notwithstanding, each 
party shall at all times have the right to take in kind or separately dispose 
of such party's share of the production from any such well, subject to the 
provisions of the applicable Program Operating Agreement.  McMoRan shall, 
however, attempt to give Participant at least seven (7) days advance written 
notice of the anticipated date of first deliveries of any production from a 
Prospect.


                                      XV.
                          Relationship of the Parties

        15.1  Tax Partnership. This Agreement is not intended and shall not be 
considered to create a partnership within the meaning of the federal common 
law or under the applicable laws of any state or under the laws of the state 
in which any party hereto is incorporated, organized or conducting business or 
to create a relationship whereby any of the parties shall be held liable for 
the acts, either of omission or commission, of any other party thereto; 
provided, however, that in the event a party 


                                     IV-15
<PAGE>
 
should suffer a loss by reason of an unauthorized act of the other party hereto,
the latter shall indemnify and save harmless the former.

        The parties expressly agree that no party hereto shall be responsible 
for the obligations of any other party, each party being severally responsible 
only for its obligations arising hereunder and liable only for its allocated 
share of the costs and expenses incurred hereunder.  It is not the purpose or 
intention of this Agreement to create, and this Agreement should never be 
construed as creating, a relationship whereby any of the parties shall be held 
liable for acts, either of omission or commission, of any other party hereto. 
Notwithstanding the foregoing, each party hereto agrees that this Agreement 
creates a partnership for Federal and State income tax reporting purposes 
only, which tax partnership shall function and exist in accordance with the 
terms and provisions of Exhibit IV attached hereto.  McMoRan agrees to provide 
to the Participant on a best efforts basis, by April 30th of each year, any 
information available to it relating to operations conducted pursuant to the 
Program that is necessary for Participant to prepare Schedule K-1 of its 
federal income tax return.

                         Special Non-Consent Elections

        17.1  Casing Point Election - Onshore Prospects. At such time as an 
Exploratory Well has been drilled to the final total depth on an Onshore 
Prospect, McMoRan shall notify Participant that the Casing Point has been 
reached on such well, and whether or not McMoRan recommends that an attempt be 
made to complete such well.  McMoRan shall also furnish, if requested in 
writing by Participant, the estimated costs of completing and equipping the 
well and plugging and abandoning same if the completion is unsuccessful, and 
all well logs, core analyses and other information in its possession not 
theretofore furnished relevant to evaluation of a completion attempt.  Within 
forty-eight (48) hours (inclusive of Saturday, Sunday and legal holidays) of 
receipt of such recommendation, Participant shall advise McMoRan whether or 
not it desires to participate in the recommended completion attempt. If 
McMoRan and Participant agree to attempt completion, McMoRan shall thereupon 
be authorized to proceed with the completion attempt and to charge the cost 
thereof as a Development Expenditure; provided, however, the cost of plugging 
and abandoning the well shall be charged as an Exploration Expenditure if the 
completion attempt is unsuccessful.  If Participant does not elect to 
participate in such completion attempt, it shall have no further rights 
hereunder as to the Prospect involved.  If McMoRan recommends abandonment 
without a completion attempt, McMoRan shall have the well plugged and 
abandoned, charging the cost thereof 


                                     IV-16
<PAGE>
 
as an Exploration Expenditure. Additionally, if Participant does not elect to
participate in a second or subsequent Exploratory Well in a particular Prospect,
Participant shall have no further rights hereunder as to the Prospect involved.

        17.2  Elections Prior to Platform Installation - Offshore Prospects. If 
Participant does not elect to participate in (a) the drilling of any well on 
an Offshore Prospect proposed by McMoRan to be drilled after the drilling of 
the first two (2) Exploratory Wells thereon and prior to the installation of 
the first drilling and/or production platform on such Prospect or (b) 
Participant does not elect to participate in the installation of the first 
drilling and/or production platform on such Prospect, the Participant shall 
have no further rights hereunder as to the Prospect involved.

        Time Periods. Whenever an election right is provided in the body of this
Agreement and no time period for response is stipulated then the applicable time
periods provided in the applicable Program Operating Agreement shall apply.

        Completion Attempt by Participant - Onshore. If McMoRan does not 
recommend the completion of an Onshore Exploratory Well and Participant 
advises McMoRan within forty-eight (48) hours (inclusive of Saturday, Sunday 
and legal holidays) of the receipt by Participant of such recommendation from 
McMoRan that Participant elects to attempt to complete such well, McMoRan 
shall undertake the completion thereof, and any subsequent plugging and 
abandoning thereof, for the account of Participant and Participant shall bear 
all costs, risks and expenses of such completion attempt and abandonment 
thereof and Participant agrees to indemnify and hold McMoRan harmless 
therefrom.  If such completion attempt is successful McMoRan will assign 
Participant all of its interest in the borehole of such well and any 
production therefrom, but such assignment shall not confer any additional 
interest to the Participant in the balance of the particular Prospect 
involved.


                                    XVIII.
                                 Program Term

        Program Term. The Program Term shall commence on ____________ and shall 
terminate, except for completion of operations which were theretofore 
commenced or committed, on the earlier of five (5) years from the date hereof, 
or the date that all of the Exploration Fund has been spent or committed.  At 
the end of the Program Term, McMoRan shall provide Participant with a list 
(the "Committed List") of the undrilled wells, Prospects and farmout 
agreements as to which it has committed the Exploration Fund.  Once such 
Committed List has been provided to Participant, no substitution shall be made 
by McMoRan without the consent of Participant.

        Unfunded Prospects. At the same time as McMoRan submits the Committed 
List, McMoRan shall also submit a listing of all Prospects which would have 
been committed to the Exploration Program except for the fact that the 
Exploration Fund had been fully expended and/or committed.  Within fifteen 
(15) days of receipt of such listing from McMoRan, Participant will have the 
option 


                                     IV-17
<PAGE>
 
to commit additional funds to the Exploration Fund for the drilling of the first
Exploratory Well on any such Prospect or Prospects or to advise MOXY that it
does not elect to so commit any such additional funds. If the Participant does
so commit, the drilling of such first Exploratory Well on a Prospect where
Participant commits such additional funds shall be charged as Exploration
Expenditures and shall be deemed included in the Committed List. If the
Participant does not commit such addi-tional funds for a Prospect on such
listing, MOXY shall have the right to acquire Participant's interest in such
Prospect, free of any liens, burdens, or overriding royalties not provided for
by Article XI hereof, by reimbursing Participant for any direct costs incurred
by Participant in acquiring Leasehold Interests in such Prospect; if MOXY so
reimburses Participant, such Prospect shall be excluded from this Agreement and
Participant shall have no further right hereunder as to such Prospect.


                                     XIX.
                         Operations After Program Term

        19.1  General. After the Program Term, all Leasehold Interests of the 
Program will be subject to the provisions of the applicable Program Operating 
Agreement and the provisions of this Agreement except as set forth in 
Paragraph 18.2 and this Article XIX.  Any Leasehold Interest which is included 
in a Prospect on which an Exploratory Well has been committed as shown on the 
Committed List shall become subject to this Article XIX after the drilling of 
such committed well.

        19.2  Exploratory Wells. After the Program Term, McMoRan and/or 
Participant shall have the right to propose the drilling of an Exploratory 
Well on a Prospect in accordance with Paragraph 9.2 hereof.

        19.3  Development Expenditures. All Development Expenditures shall be 
borne by the parties according to their interest and subject to the provisions 
of the applicable Program Operating Agreement, whether incurred before or 
after the Program Term.

        19.4  Provisions Which Do Not Survive the End of the Program Term. From 
and after the end of the Program Term, McMoRan shall have no right to commit 
Participant to any expenditures except in accordance with the applicable 
Program Operating Agreement and with respect to the conclusion of then 
drilling or committed operations.  McMoRan shall have no obligation thereafter 
to offer Participant the right to acquire any Leasehold Interest unless such 
acquisition is subject to an AMI agreement with Participant.  Further, McMoRan 
shall have no further right to bind Participant's interest to any trade 
agreement except as may be expressly authorized by Participant.

                               Confidentiality.

        20.1  Confidentiality. Except to the extent provided to the contrary 
hereunder and subject to any agreements with third parties entered into 
pursuant to the Program, each party agrees that at 


                                     IV-18
<PAGE>
 
all times prior to, but not after, December 31, 2007, it will take all
reasonable steps to keep secret and confidential and not disclose to any third
party, geological or geophysical data, progress reports or other information
which it may receive as a result of operations carried out under this Agreement;
provided, however, that these restrictions shall not apply to information which
(i) is in, or has entered into, the public domain without breach of the
provisions of this Paragraph 20.1; (ii) is in the possession of a party
receiving same as a result of prior receipt thereof from another party (not a
party to this Agreement) prior to the time of such receipt under this Agreement,
(iii) may lawfully be obtained as a matter of right by the party receiving same
from another source, (iv) is required to be disclosed by law or the rules of any
governmental agency or an applicable stock exchange, by McMoRan or Participant,
or (v) is furnished to Affiliates, or to bona fide prospective purchasers,
mortgagees, prospective mortgagees, lenders, prospective lenders, prospective
joint program participants and consultants for evaluation purposes provided that
any person furnished information pursuant to this clause (v) agrees not to
communicate such information to any other party or to use it for their own
benefit in a manner adverse to the interests of McMoRan and/or Participant.
Notwithstanding the foregoing, the parties recognize that from time to time
information (such as logs) may be acquired by the Program which should not be
disclosed to anyone other than those persons who must have such information.
Each party shall take all reasonable steps to require its employees and
consultants to be bound by the provisions of this paragraph in the same manner
as it is bound hereunder. News releases concerning discoveries or operations of
the Program shall only be made in accordance with guidelines attached to the
applicable Program Operating Agreement, subject to the requirements of
applicable laws and regulations and requirements of applicable stock exchanges.

                                   Insurance

Exploration Program, procure and maintain with responsible companies insurance 
in the amounts and covering the risks set forth below:

        (a)   Worker's Compensation:
              Such insurance shall be in full compliance with the law in the

              voluntary compensation endorsement and a waiver of subrogation as
              to Participant. Where applicable, coverage shall also be provided

<PAGE>
 
              (i)   Maritime (Amendment to Coverage B), to include  
                    transportation, wages, maintenance and cure.
              (ii)  A claim "in rem" will be treated as a claim "in personam".
              (iii) A waiver of subrogation as to Participant.

        (c)   All vessels owned or chartered by McMoRan shall be adequately
 covered by Hull and Protection and Indemnity Insurance.
 
        (d)   No insurance other than as specified above shall be provided by

        (f)   Upon request, certificates of insurance evidencing the insurance
obtained by McMoRan hereunder shall be furnished to Participant.

        (g)   Unless otherwise agreed in writing, McMoRan and Participant

                           Record Title, Assignment

        22.1  Record Title. For convenience, McMoRan shall initially hold record
title to the Leasehold Interests acquired hereunder; provided however, upon
written request by Participant, McMoRan will, within 120 days following the
completion by the Program on an Onshore Prospect of a well capable of producing
in paying quantities, or within 120 days following the installation of the first
drilling and/or production platform on an Offshore Prospect by the Program, as
applicable, execute and deliver to Participant a recordable assignment of
Participant's interest in all Leasehold Interests in such Prospect, unless
Participant has no further rights hereunder as to a particular Prospect as the
result of a decision not to participate pursuant to Paragraph 17.1, Paragraph
17.2 or Paragraph 18.2, as applicable. In addition, at the end of Program Term
McMoRan shall execute and deliver to Participant a recordable assignment of
Participant's interest in any Leasehold Interest not included in a Prospect
during the Program Term pursuant to any provision of this Agreement. Such
assignment shall warrant title against all parties claiming by, through or under
McMoRan, but not otherwise; but McMoRan shall assign to Participant, with full
right of subrogation, to the extent so transferable, the benefit of and the
right to enforce the covenants and warranties, if any, which McMoRan is entitled
to enforce with respect to the interest assigned or any part thereof. Each
assignment shall be subject to this Agreement and shall be charged with and
burdened by the proportionate part of the royalties provided for in each lease
covered thereby, any overriding royalty or similar interest with which such
Leasehold Interests are burdened as authorized by Paragraph 11.1 hereof and any
other contracts or agreements with which such Leasehold Interests are burdened
by McMoRan as expressly authorized by other provisions of this Agreement and
which continue to burden such Leasehold Interests at the time of such
assignment. If, however, there are restrictions on assignability with respect to
a Prospect or Leasehold Interest prohibiting McMoRan as nominee for the Program
from transferring interests in such Prospect or Leasehold Interest, McMoRan
shall continue to hold record title in its name on behalf of the parties owning
interests therein rather than for the Program, and at the request of such
parties will execute a mutually acceptable nominee agreement.

        Assignment. Except as permitted below, without the prior written consent
of the other party, neither McMoRan nor Participant shall assign any rights in
this Agreement. Until the Program has completed a well capable of production in
Paying Quantities on an Onshore Prospect or prior to the election provided in
Paragraph XVII hereof as to an Offshore Prospect, or the end of the Program
Term, whichever first occurs, no party hereto may assign its interest in the
Leasehold Interests within said Prospect acquired pursuant to the Program
without first obtaining the consent of the other party hereto (which approval
will not be unreasonable withheld); provided that granting of a lien or security
interest by any party shall not require such consent. The assignees of any
Leasehold Interest acquired pursuant to the Program shall be bound by all of the
assignor's obligations with respect to such Leasehold Interest as to the
interest assigned. Notwithstanding the foregoing, either Participant or McMoRan
without the necessity of obtaining consent may transfer all or any part of its
interests and rights in this Agreement or in any Prospect to any Affiliate
provided that the assigning party shall remain liable hereunder. Notwithstanding
the foregoing, if a Prospect involves the acquisition of a Leasehold interest
from a third party, the period hereinabove provided for the delivery of
assignments shall be extended, if required, until 60 days following the receipt
of an assignment of interest by McMoRan from such third party; provided however,
in the event that such an assignment requires the approval of a governmental
authority then such period will be extended for 60 days 


                                     IV-21
<PAGE>
 
following the receipt by McMoRan of the required approval from the governmental
authority.


                                    XXIII.
                             Subsequent Interests

        23.1  Subsequent Interest. Except with respect to burdens described in 
Paragraph 11.1, or as otherwise provided in this Agreement, a party who 
creates any burden against such party's interest in any Leasehold Interest 
shall be solely responsible for such burden; and in the event such party is 
required, pursuant to other provisions of this Agreement including the 
applicable Program Operating Agreement or a third party operating agreement, 
to assign its interest in any Leasehold Interest to any other party, such 
assignment shall convey and vest title to such interest in such assignee free 
and clear of any such burden.


                                     XXIV.
                                    General

        24.1  Records. McMoRan shall maintain complete and accurate records of 
all Leasehold Interests acquired and held hereunder, the acquisition and 
disposition of all equipment hereunder, and of all expenditures made hereunder 
in accordance with generally accepted industry standards.  McMoRan will 
maintain complete and accurate records of all correspondence with any operator 
who may be operating properties in which the parties hereto have an interest 
under this Agreement, and will retain a copy of all statements, bills and 
other instruments furnished by any such operator in accordance with generally 
accepted industry standards.  Such records, together with receipts, vouchers 
and other supporting evidence thereof in McMoRan's possession and control, 
will be available for inspection, copying and audit by Participant or its duly 
authorized representatives on reasonable notice at McMoRan's office during 
regular business hours then in effect.  Participant's right to audit McMoRan's 
records for the purpose of challenging the correctness of any charge made by 
McMoRan hereunder shall terminate as provided in the accounting procedure 
attached to the Program Operating Agreement.  Participant shall be entitled to 
join McMoRan in any audit made by McMoRan of the records of third party 
operators of properties in which Participant acquired an interest under this 
Agreement.  At the request of Participant, McMoRan shall conduct or cause to 
be conducted an audit of the records of any such third party operator 
hereunder, said audit right to be as specified in such third party agreement 
including the polling of other non-operators to determine if they desire to 
participate, at which time McMoRan may decline to participate and therefore 
not bear any cost related to such audit.  In addition, Participant shall have 
the same audit rights as held by McMoRan under third party agreements 
including the right to elect participation in any audit performed by another 
non-operator if McMoRan elects not to participate in such audit and 
Participant shall receive copies of all reports of joint venture audits which 
are conducted.  

        24.2  Access. Participant or its duly authorized representative shall 
have access at all reasonable times, at its expense and risk, to the derrick 
floor of any well being drilled hereunder in 


                                     IV-22
<PAGE>
 
which Participant is participating; and Participant shall have the right to
inspect all materials on hand for the account of the Program and to observe any
such operations conducted hereunder.

        24.3  Claims and Litigation. Except as to matters arising with respect 
to a particular Prospect after the Program Operating Agreement has become 
applicable as to all further operations thereon under the provisions of this 
Agreement (as to which the provisions of such Program Operating Agreement will 
govern), all investigation, litigation and settlements in connection with 
titles, claims and causes of action of every kind and joint rights and 
interests of McMoRan and Participant in the Program Area in connection with 
the Program shall be carried on, conducted and defended for and on behalf of 
McMoRan and Participant.  Each party shall notify the other of any process 
served upon it in any such suit or claim.  Where a claim has been made or a 
suit has been filed against McMoRan or Participant for damages caused by or 
arising out of operations the expense of which is charged to the Exploration 
Fund as authorized herein, McMoRan shall retain legal counsel to handle the 
defense of such suit or claim and notify Participant of the retention of such 
legal counsel.  The cost of such legal services shall be charged in the same 
manner as Exploration Expenditures are charged.  Participant may, if it so 
chooses, elect to retain its own legal counsel (at Participant's expense) to 
defend its interests in any such suit or claim; and in such event the claim or 
suit shall be defended by a committee of attorneys selected by and 
representing the separate interests of McMoRan and Participant (with such 
party being responsible for the fees and expenses of its own counsel), with 
McMoRan's counsel as chairperson.  All settlements of suits and claims shall 
be subject to the approval of Participant; except that McMoRan may settle any 
claim under $100,000 without first receiving Participant's approval, provided 
the payment is in complete settlement.  The costs and expenses involved in 
those matters which are subject to the provisions of this Paragraph 24.3 shall 
be shared and borne solely by the parties who participated in such operation 
or Leasehold Interest in proportion to their respective participation in the 
applicable operation or Leasehold Interest.  McMoRan agrees to keep 
Participant advised as to claims for which Participant may be partly 
responsible hereunder.

        24.4    Good Faith. McMoRan and Participant agree to act in good faith 
with respect to their respective activities under this Agreement.

        24.5    Governing Law. This Agreement and the documents provided for 
herein shall be deemed to be governed by, and construed in accordance with, 
the laws of the State of Louisiana.

        24.6    Failure to Respond. Except as provided in Paragraph 10.1 hereof,
whenever under this Agreement (exclusive of the applicable Program Operating
Agreement) Participant is given the right to approve or disapprove or
participate or decline to participate in a proposed operation or acquisition;
failure to respond shall be deemed a response to disapprove or decline to
participate in the proposed operation or acquisition unless McMoRan is
recommending and electing to plug and abandon a well, in which event failure to
respond shall be an election to plug and abandon.

        24.7  Conflicts. Should there be any conflict between the body of this
Agreement and any Exhibit hereto, the provisions contained in the body of this
Agreement shall control.

        24.8  Binding Effect. This Agreement shall be binding upon and inure to 
the benefit of the parties hereto and their respective successors and assigns; 
provided, however, nothing herein contained shall be construed as permitting 
an assignment contrary to the terms and provisions of this Agreement.

Board of Directors
McMoRan Oil & Gas Co.
1615 Poydras Street
New Orleans, LA  70112

Ladies and Gentlemen:

        You have requested our opinion as to the fairness from a financial point
of view to the stockholders of McMoRan Oil & Gas Co. ("MOXY" or the "Company")
of the financial terms of the Transactions (as defined below) contemplated by
the Master Agreement, dated as of July 14, 1997 (the "Master Agreement"), by and
between Freeport-McMoRan Resource Partners, Limited Partnership ("FRP") and the
Company pursuant to which, among other things, (i) FRP will purchase MCN Corp.'s
("MCN") interest in the MOXY/MCN Program, (ii) MOXY and MCN will amend the
MOXY/MCN Program Agreement, (iii) MOXY will conduct the Rights Offering, (iv)
FRP will provide the Standby Commitment and receive the FRP Purchase Option and
the fees provided for in the Standby Purchase Agreement, (v) MOXY and FRP will
enter into the Stockholder Agreement, (vi) MOXY will purchase the MCN producing
properties from FRP and (vii) MOXY and FRP will convey certain properties to the
MOXY/FRP Exploration Program and commence operations thereunder pursuant to the
Participation Agreement. Such transactions to be effected pursuant to the terms
of the Master Agreement are hereinafter referred to collectively as the
"Transactions," and all other capitalized terms used herein and not defined
shall have the meaning ascribed to such terms in the Master Agreement or the
exhibits thereto.

        In arriving at our opinion, we have reviewed (i) the draft dated July
14, 1997 of the Master Agreement and the exhibits thereto, including the MCN
Purchase Agreement, the MOXY/MCN Program Amendment, the Stockholder Agreement
and the Participation Agreement, (ii) drafts, dated July 14, 1997, of MOXY's
proxy statement and MOXY's registration statement on Form S-3 and (iii) such
other financial and other information as was publicly available or furnished to
us by the Company, including 


                                      V-1
<PAGE>
 
information provided during discussions with management of the Company. Included
in the information provided during discussions with management were certain
financial projections of the Company for the period beginning January 1, 1997
and ending December 31, 1998 prepared by the management of the Company. In
addition, we have compared certain financial and securities data of the Company
with various other companies whose securities are traded in public markets,
reviewed the historical stock prices and trading volumes of the common stock,
par value $.01 per share ("Common Stock"), of the Company, reviewed prices and
premiums paid in comparable transactions and in certain business combinations
and conducted such other financial studies, analyses and investigations as we
deemed appropriate for purposes of this opinion. We were not requested to, nor
did we, solicit the interest of any other party in acquiring the Company. We
have also considered the Company's immediate need for additional cash to fund
its capital, operating and growth requirements, and the alternatives available
to the Company to obtain additional debt or equity financing.

        In rendering our opinion, we have relied upon and assumed the accuracy
and completeness of all of the financial and other information that was
available to us from public sources, that was provided to us by the Company or
its representatives, or that was otherwise reviewed by us. With respect to any
financial projections supplied to us, we have assumed that they have been
reasonably prepared on the basis reflecting the best currently available
estimates and judgments of the management of the Company as to the future
operating and financial performance of the Company. We have not assumed any
responsibility for making an independent evaluation of the Company's assets or
liabilities or for making any independent verification of any of the information
reviewed by us. We also understand that the Standby Commitment may result in a
change of control of MOXY. We have relied as to certain legal matters on advice
of counsel to the Company.

        Our opinion is necessarily based on economic, market, financial and
other conditions as they exist on, and on the information made available to us
as of, the date of this letter. It should be understood that, although
subsequent developments may affect this opinion, we do not have any obligation
to update, revise or reaffirm this opinion. We are expressing no opinion herein
as to the price at which the Common Stock will actually trade at any time. Our
opinion does not address the relative merits of the Transactions and the other
business strategies being considered by the Company's Board of Directors, nor
does it address the Board's decision to proceed with the Transactions.
Furthermore, our opinion does not constitute a recommendation

                                  ARTICLE III

                           ADMINISTRATION OF THE PLAN

          This Plan shall be administered by the Board.  The Board will
interpret this Plan and may from time to time adopt such rules and regulations
for carrying out the terms and provisions of this Plan as it may deem best;
however, the Board shall have no discretion with respect to the selection of
directors who receive Options, the timing of the grant of Options, the number of
Shares subject to any Options or the purchase price thereof.  Notwithstanding
the foregoing, the Committee shall have the authority to make all determinations
with respect to the transferability of Options in accordance with Article VIII
hereof.  All determinations by the Board or the Committee shall be made by the
affirmative vote of a majority of its respective members, but any determination
reduced to writing and signed by a majority of its respective members shall be
fully as effective as if it had been made by a majority vote at a meeting duly
called and held.  Subject to any applicable

                                     VI-2
<PAGE>
 
provisions of the Company's By-Laws or of this Plan, all determinations by the
Board and the Committee pursuant to the provisions of this Plan, and all related
orders or resolutions of the Board and the Committee, shall be final, conclusive
and binding on all persons, including the Company and its stockholders,
employees, directors and optionees.  In the event of any conflict or
inconsistency between determinations, orders, resolutions, or other actions of
the Committee and the Board taken in connection with this Plan, the action of
the Board shall control.


                                   ARTICLE IV

                           STOCK SUBJECT TO THE PLAN

          SECTION 1.  The Shares to be issued or delivered upon exercise of
Options shall be made available, at the discretion of the Board, either from the
authorized but unissued Shares of the Company or from Shares reacquired by the
Company, including Shares purchased by the Company in the open market or
otherwise obtained; provided, however, that the Company, at the discretion of
the Board, may, upon exercise of Options granted under this Plan, cause a
Subsidiary to deliver Shares held by such Subsidiary.

          SECTION 2.  Subject to the provisions of Section 3 of this Article IV,
the aggregate number of Shares which may be purchased pursuant to Options shall
not exceed [250,000] 410,000.

          SECTION 3.  In the event of the payment of any dividends payable in
Shares, or in the event of any subdivision or combination of the Shares, the
number of Shares which may be purchased under this Plan, and the number of
Shares subject to each Option granted in accordance with SectionS 2, 3, AND 4 of
Article VII, shall be increased or decreased proportionately, as the case may
be, and the number of Shares deliverable upon the exercise thereafter of any
Option theretofore granted (whether or not then exercisable) shall be increased
or decreased proportionately, as the case may be, without change in the
aggregate purchase price.  In the event the Company is merged or consolidated
into or with another corporation in a transaction in which the Company is not
the survivor, or in the event that substantially all of the Company's assets are
sold to another entity not affiliated with the Company, any holder of an Option,
whether or not then exercisable, shall be entitled to receive (unless the
Company shall take such alternative action as may be necessary to preserve the
economic benefit of the Option for the optionee) on the effective date of any
such transaction (the "Option Cancellation Date"), in cancellation of such
Option, an amount in cash equal to the Option Cancellation Gain relating
thereto, determined as of the Option Cancellation Date.


                                   ARTICLE V

                       PURCHASE PRICE OF OPTIONED SHARES

          The purchase price per Share under each Option shall be 100% of the
Fair Market Value of a Share at the time such Option is granted, but in no case
shall such price be less than the par value of the Shares subject to such
Option.


                                   ARTICLE VI

                           ELIGIBILITY OF RECIPIENTS

at the time of such grant.

thereof with respect to all or any part of the Shares comprising each

HOLDER THEREOF WITH RESPECT TO ALL OR ANY PART OF THE SHARES COMPRISING EACH
INSTALLMENT AS SUCH HOLDER MAY ELECT AT ANY TIME AFTER SUCH INSTALLMENT BECOMES
EXERCISABLE BUT NO LATER THAN THE TERMINATION DATE OF SUCH OPTION; PROVIDED THAT
EACH SUCH OPTION SHALL BECOME EXERCISABLE IN FULL UPON A CHANGE IN CONTROL.

          SECTION 4.  ON JUNE 1, 1998 AND JUNE 1 OF EACH SUBSEQUENT YEAR THROUGH

                                  ARTICLE VIII

                           TRANSFERABILITY OF OPTIONS

          No Options granted hereunder may be transferred, pledged, assigned or
otherwise encumbered by an optionee except:

          (a)  by will;

          (b) by the laws of descent and distribution; or

          (c)  if permitted by the Committee and so provided in the Option or an
     amendment thereto, (i) pursuant to a domestic relations order, as defined
     in the Code, (ii) to Immediate Family Members, (iii) to a partnership in

     Members, or entities in which Immediate Family

                                     VI-4
<PAGE>
 
     Members are the owners, members or beneficiaries, as appropriate, are the
     members, or (v) to a trust for the benefit of Immediate Family Members;
     provided, however, that no more than a de minimus beneficial interest in a
     partnership, limited liability company or trust described in (iii), (iv) or
     (v) above may be owned by a person who is not an Immediate Family Member or
     by an entity that is not beneficially owned solely by Immediate Family
     Members.  "Immediate Family Members" shall be defined as the spouse and
     natural or adopted children or grandchildren of the optionee and their
     spouses.

Any attempted assignment, transfer, pledge, hypothecation or other disposition
of Options, or levy of attachment or similar process upon Options not
specifically permitted herein, shall be null and void and without effect.


                                   ARTICLE IX

                              EXERCISE OF OPTIONS

          SECTION 1.  Each Option shall terminate 10 years after the date on
which it was granted.

Option may be exercised by the holder thereof only while the optionee to whom
such Option was granted is an Eligible Director.

          SECTION 3.  Each Option shall provide that the Option or any portion
thereof may be exercised only during an Election Period.  Each Option shall
provide, however, that in the event of a Change in Control, the Election Period
exercise requirement is waived.

          SECTION 4.  A person electing to exercise an Option or any portion
thereof then exercisable shall give written notice to the Company of such
election and of the number of Shares such person has elected to purchase, and
shall at the time of purchase tender the full purchase price of such Shares,
which tender shall be made in cash or cash equivalent (which may be such
person's personal check) or in Shares already owned by such person (which Shares
shall be valued for such purpose on the basis of their Fair Market Value on the
date of exercise), or in any combination thereof.  The Company shall have no
obligation to deliver Shares pursuant to the exercise of any Option, in whole or
in part, until such payment in full of the purchase price of such Shares is
received by the Company.  No optionee, or legal representative, legatee,
distributee, or assignee of such optionee shall be or be deemed to be a holder
of any Shares subject to such Option or entitled to any rights of a stockholder
of the Company in respect of any Shares covered by such Option distributable in
connection therewith until such Shares have been paid for in full and
certificates for such Shares have been issued or delivered by the Company.

          SECTION 5.  Each Option shall be subject to the requirement that if at
any time the Board shall be advised by counsel that the listing, registration or
qualification of the Shares subject to such Option upon any securities exchange
or under any state or federal law, or the consent or approval of any
governmental regulatory body, is necessary or desirable as a condition of, or in
connection with, the granting of such Option or the issue or purchase of Shares
thereunder, such Option may not be exercised in whole or in part unless such
listing, registration, qualification, consent or approval shall have been
effected or obtained free from any conditions not reasonably acceptable to such
counsel for the Board.

          SECTION 6.  The Company may establish appropriate procedures to
provide for payment or withholding of such income or other taxes as may be
required by law to be paid or withheld in connection with the exercise of
Options, and to ensure that the Company receives prompt advice concerning the
occurrence of any event which may create, or affect the timing or amount of, any
obligation to pay or withhold

                                     VI-5
<PAGE>
 
any such taxes or which may make available to the Company any tax deduction
resulting from the occurrence of such event.

within three months after such optionee ceases to be an Eligible Director, but
not later than the termination date of the Option.

Director by reason of the optionee's retirement from the Board, all of the
Options granted to such optionee shall be terminated except that any Option, to
the extent then exercisable or exercisable within one year thereafter, may be
exercised by the holder thereof within three years after such retirement, but
not later than the termination date of the Option.

          SECTION 3.  Should an optionee die while serving as an Eligible
Director, all the  Options granted to such optionee shall be terminated, except
that any Option to the extent exercisable by the holder thereof  at the time of
such death, together with the unmatured installment (if any) of such Option
which at that time is next scheduled to become exercisable, may be exercised
within one year after the date of such death, but not later than the termination
date of the Option, by the holder thereof, the optionee's estate, or the person
designated in the optionee's last will and testament, as appropriate.

          SECTION 4.  Should an optionee die after ceasing to be an Eligible
Director, all of the Options granted to such optionee shall be terminated,
except that any Option, to the extent exercisable by the holder thereof at the
time of such death, may be exercised within one year after the date of such
death, but not later than the termination date of the Option, by the holder
thereof, the optionee's estate, or the person designated in the optionee's last

without the approval of the stockholders shall:

          (a)  except pursuant to Section 3 of Article IV, increase the maximum
     number (determined as provided in this Plan) of Shares which may be
     purchased pursuant to Options, either individually or in aggregate;

          (b)  permit the granting of any Option at a purchase price other than
     100% of the Fair Market Value of the Shares at the time such Option is
     granted, subject to adjustment pursuant to Section 3 of Article IV;

                                   SECTION 3

          Administration.  The Plan shall be administered by the Committee.
Subject to the terms of the Plan and applicable law, and in addition to other
express powers and authorizations conferred on the Committee by the Plan, the
Committee shall have full power and authority to:  (i) designate Participants;
(ii) determine the type or types of Awards to be granted to an eligible

to which payments, rights or other matters are to be calculated in connection

method or methods by which Awards may be settled, exercised, cancelled,

the sole discretion of the Committee, may be made at any time and shall be
final, conclusive and binding upon all Persons, including the Company, any
Subsidiary, any Participant, any holder or beneficiary of any Award, any
stockholder of the Company and any Employee.


                                   SECTION 4

          Eligibility. Any Employee who is not a member of the Committee shall
be eligible to be granted an Award.


                                   SECTION 5

          (a) Shares Available for Awards. Subject to adjustment as provided in
Section 5(b):

          (i)  Calculation of Number of Shares Available.   The number of Shares
with respect to which Awards may be granted under the Plan shall be [1,000,000]
3,000,000.  If, after the effective date of the Plan, an Award granted under the
Plan expires or is exercised, forfeited, cancelled or terminated without the
delivery of Shares, 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
expiration, exercise, forfeiture, cancellation or termination without the
delivery of Shares, shall again be, or shall become, Shares with respect to
which Awards may be granted.

          (ii)  Substitute Awards.  Any Shares delivered by the Company, any
Shares with respect to which Awards are made by the Company, or any Shares with
respect to which the Company becomes


                                     VII-3
<PAGE>
 
obligated to make Awards, through the assumption of, or in substitution for,
outstanding awards previously granted by an acquired company or a company with
which the Company combines, shall not be counted against the Shares available
for Awards under the Plan.

          (iii)  Sources of Shares Deliverable Under Awards.  Any Shares
delivered pursuant to an Award may consist of authorized and unissued Shares or
of treasury Shares, including Shares held by the Company or a Subsidiary and
acquired in the open market or otherwise obtained by the Company or a
Subsidiary.

          (iv)  Individual Limit.  Any provision of the Plan to the contrary
notwithstanding, no individual may receive in any year Awards under the Plan
that relate to more than [200,000] 600,000 Shares.

          (b)  Adjustments.  In the event that the Committee determines that any
dividend or other distribution (whether in the form of cash, Shares, Subsidiary
securities, other securities or other property), recapitalization, stock split,
reverse stock split, reorganization, merger, consolidation, split-up, spin-off,
combination, repurchase or exchange of Shares or other securities of the
Company, issuance of warrants or other rights to purchase Shares or other
securities of the Company, or other similar corporate transaction or event
affects the Shares such that an adjustment is determined by the Committee to be
appropriate to prevent dilution or enlargement of the benefits or potential
benefits intended to be made available under the Plan, then the Committee may,
in its sole discretion and in such manner as it may deem equitable, adjust any
or all of (i) the number and type of Shares (or other securities or property)
with respect to which Awards may be granted, (ii) the number and type of Shares
(or other securities or property) subject to outstanding Awards, and (iii) the
grant or exercise price with respect to any Award or, if deemed appropriate,
make provision for a cash payment to the holder of an outstanding Award or, if
deemed appropriate, adjust outstanding Awards to provide the rights contemplated
by Section 9(b) hereof; provided, in each case, that with respect to Awards of
Incentive Stock Options no such adjustment shall be authorized to the extent
that such authority would cause the Plan to violate Section 422(b)(1) of the
Code or any successor provision thereto and, with respect to all Awards under
the Plan, no such adjustment shall be authorized to the extent that such
authority would be inconsistent with the requirements for full deductibility
under Section 162(m) of the Code and the regulations thereunder; and provided
further, that the number of Shares subject to any Award denominated in Shares
shall always be a whole number.


                                   SECTION 6

          (a)  Stock Options.  Subject to the provisions of the Plan, the
Committee shall have sole and complete authority to determine the Employees to
whom Options shall be granted, the number of Shares to be covered by each
Option, the option price therefor and the conditions and limitations applicable
to the exercise of the Option.   The Committee shall have the authority to grant
Incentive Stock Options, Nonqualified Stock Options or both.   In the case of
Incentive Stock Options, the terms and conditions of such grants shall be
subject to and comply with such rules as may be required by Section 422 of the
Code, as from time to time amended, and any implementing regulations.  Except in
the case of an Option granted in assumption of or substitution for an
outstanding award of a company acquired by the Company or with which the Company
combines, the exercise price of any Option granted under this Plan shall not be
less than 100% of the fair market value of the underlying Shares on the date of
grant.

          (b)  Exercise.  Each Option shall be exercisable at such times and
subject to such terms and conditions as the Committee may, in its sole
discretion, specify in the applicable Award Agreement or thereafter, provided,
however, that in no event may any Option granted hereunder be exercisable after
the expiration of 10 years after the date of such grant.  The Committee may
impose such conditions with respect to the exercise of Options, including
without limitation, any condition relating to the application of Federal or
state securities laws, as it may deem necessary or advisable.


                                     VII-4
<PAGE>
 
          (c)  Payment.  No Shares shall be delivered pursuant to any exercise
of an Option until payment in full of the option price therefor is received by
the Company.  Such payment may be made in cash, or its equivalent, or, if and to
the extent permitted by the Committee, by applying cash amounts payable by the
Company upon the exercise of such Option or other Awards by the holder thereof
or by exchanging whole Shares owned by such holder (which are not the subject of
any pledge or other security interest), or by a combination of the foregoing,
provided that the combined value of all cash, cash equivalents, cash amounts so
payable by the Company upon exercises of Awards and the fair market value of any
such whole Shares so tendered to the Company, valued (in accordance with
procedures established by the Committee) as of the effective date of such
exercise, is at least equal to such option price.


                                   SECTION 7

          (a)  Stock Appreciation Rights. Subject to the provisions of the
Plan, the Committee shall have sole and complete authority to determine the
Employees to whom Stock Appreciation Rights shall be granted, the number of
Shares to be covered by each Stock Appreciation Right, the grant price thereof
and the conditions and limitations applicable to the exercise thereof.  Stock
Appreciation Rights may be granted in tandem with another Award, in addition to
another Award, or freestanding and unrelated to any other Award. Stock
Appreciation Rights granted in tandem with or in addition to an Option or other
Award may be granted either at the same time as the Option or other Award or at
a later time.  Stock Appreciation Rights shall not be exercisable after the
expiration of 10 years after the date of grant. Except in the case of a Stock
Appreciation Right granted in assumption of or substitution for an outstanding
award of a company acquired by the Company or with which the Company combines,
the grant price of any Stock Appreciation Right granted under this Plan shall
not be less than 100% of the fair market value of the Shares covered by such
Stock Appreciation Right on the date of grant or, in the case of a Stock
Appreciation Right granted in tandem with a then outstanding Option or other
Award, on the date of grant of such related Option or Award.

          (b)  A Stock Appreciation Right shall entitle the holder thereof to
receive an amount equal to the excess, if any, of the fair market value of a
Share on the date of exercise of the Stock Appreciation Right over the grant
price.  Any Stock Appreciation Right shall be settled in cash, unless the
Committee shall determine at the time of grant of a Stock Appreciation Right
that it shall or may be settled in cash, Shares or a combination of cash and
Shares.


                                   SECTION 8

          (a) Limited Rights. Subject to the provisions of the Plan, the
Committee shall have sole and complete authority to determine the Employees to
whom Limited Rights shall be granted, the number of Shares to be covered by each
Limited Right, the grant price thereof and the conditions and limitations
applicable to the exercise thereof. Limited Rights may be granted in tandem with
another Award, in addition to another Award, or freestanding and unrelated to
any Award. Limited Rights granted in tandem with or in addition to an Award may
be granted either at the same time as the Award or at a later time. Limited
Rights shall not be exercisable after the expiration of 10 years after the date
of grant and shall only be exercisable during a period determined at the time of
grant by the Committee beginning not earlier than one day and ending not more
than ninety days after the expiration date of an Offer. Except in the case of a
Limited Right granted in assumption of or substitution for an outstanding award
of a company acquired by the Company or with which the Company combines, the
grant price of any Limited Right granted under this Plan shall not be less than
100% of the fair market value of the Shares covered by such Limited Right on the
date of grant or, in the case of a Limited Right granted in tandem with a then
outstanding Option or other Award, on the date of grant of such related Option
or Award.


                                     VII-5
<PAGE>
 
          (b)  A Limited Right shall entitle the holder thereof to receive an
amount equal to the excess, if any, of the Offer Price on the date of exercise
of the Limited Right over the grant price.  Any Limited Right shall be settled
in cash, unless the Committee shall determine at the time of grant of a Limited
Right that it shall or may be settled in cash, Shares or a combination of cash
and Shares.


                                   SECTION 9

          (a) Other Stock-Based Awards. The Committee is hereby authorized to
grant to eligible Employees an "Other Stock-Based Award", which shall consist of
an Award, the value of which is based in whole or in part on the value of
Shares, that is not an instrument or Award specified in Sections 6 through 8 of
this Plan. Other Stock-Based Awards may be awards of Shares or may be
denominated or payable in, valued in whole or in part by reference to, or
otherwise based on or related to, Shares (including, without limitation,
securities convertible or exchangeable into or exercisable for Shares), as
deemed by the Committee consistent with the purposes of the Plan. The Committee
shall determine the terms and conditions of any such Other Stock-Based Award.
Except in the case of an Other Stock-Based Award granted in assumption of or in
substitution for an outstanding award of a company acquired by the Company or
with which the Company combines, the price at which securities may be purchased
pursuant to any Other Stock-Based Award granted under this Plan, or the
provision, if any, of any such Award that is analogous to the purchase or
exercise price, shall not be less than 100% of the fair market value of the
securities to which such Award relates on the date of grant.

          (b)  Dividend Equivalents.  In the sole and complete discretion of the
Committee, an Award, whether made as an Other Stock-Based Award under this
Section 9 or as an Award granted pursuant to Sections 6 through 8 hereof, may
provide the holder thereof with dividends or dividend equivalents, payable in
cash, Shares, Subsidiary securities, other securities or other property on a
current or deferred basis.


                                  SECTION 10

          (a)  Amendments to the Plan.   The Board may amend, suspend or
terminate the Plan or any portion thereof at any time, provided that no
amendment shall be made without stockholder approval if such approval is
necessary to comply with any tax or regulatory requirement.  Notwithstanding
anything to the contrary contained herein, the Committee may amend the Plan in
such manner as may be necessary for the Plan to conform with local rules and
regulations in any jurisdiction outside the United States.

          (b)  Amendments to Awards.   The Committee may amend, modify or
terminate any outstanding Award with the holder's consent at any time prior to
payment or exercise in any manner not inconsistent with the terms of the Plan,
including without limitation, (i) to change the date or dates as of which an
Award becomes exercisable, or (ii) to cancel an Award and grant a new Award in
substitution therefor under such different terms and conditions as it determines
in its sole and complete discretion to be appropriate.

          (c)  Adjustment of Awards Upon the Occurrence of Certain Unusual or
Nonrecurring Events. The Committee is hereby authorized to make adjustments in
the terms and conditions of, and the criteria included in, Awards in recognition
of unusual or nonrecurring events (including, without limitation, the events
described in Section 5(b) hereof) affecting the Company, or the financial
statements of the Company or any Subsidiary, or of changes in applicable laws,
regulations, or accounting principles, whenever the Committee determines that
such adjustments are appropriate to prevent dilution or enlargement of the
benefits or potential benefits intended to be made available under the Plan.


                                     VII-6
<PAGE>
 
          (d)  Cancellation.  Any provision of this Plan or any Award Agreement
to the contrary notwithstanding, the Committee may cause any Award granted
hereunder to be cancelled in consideration of a cash payment or alternative
Award made to the holder of such cancelled Award equal in value to such
cancelled Award.  The determinations of value under this subparagraph shall be
made by the Committee in its sole discretion.


                                  SECTION 11

          (a)  Delegation.  Subject to the terms of the Plan and applicable law,
the Committee may delegate to one or more officers of the Company the authority,
subject to such terms and limitations as the Committee shall determine, to grant
Awards to, or to cancel, modify or waive rights with respect to, or to alter,
discontinue, suspend, or terminate Awards held by, Employees who are not
officers or directors of the Company for purposes of Section 16 of the Exchange
Act, or any successor section thereto, or who are otherwise not subject to such
Section.

          (b)  Award Agreements.   Each Award hereunder shall be evidenced by a
writing delivered to the Participant that shall specify the terms and conditions
thereof and any rules applicable thereto, including but not limited to the
effect on such Award of the death, retirement or other termination of employment
of the Participant and the effect thereon, if any, of a change in control of the
Company.

          (c)  Withholding.  A Participant may be required to pay to the
Company, and the Company shall have the right to deduct from all amounts paid to
a Participant (whether under the Plan or otherwise), any taxes required by law
to be paid or withheld in respect of Awards hereunder to such Participant.   The
Committee may provide for additional cash payments to holders of Awards to
defray or offset any tax arising from the grant, vesting, exercise or payment of
any Award.

          (d)  Transferability.  No Awards granted hereunder may be transferred,
pledged, assigned or otherwise encumbered by a Participant except: (i) by will;
(ii) by the laws of descent and distribution; (iii) pursuant to a domestic
relations order, as defined in the Code, if permitted by the Committee and so
provided in the Award Agreement or an amendment thereto; or (iv) if permitted by
the Committee and so provided in the Award Agreement or an amendment thereto,
Options and Limited Rights granted in tandem therewith may be transferred or
assigned (a) to Immediate Family Members, (b) to a partnership in which
Immediate Family Members, or entities in which Immediate Family Members are the
owners, members or beneficiaries, as appropriate, are the partners, (c) to a
limited liability company in which Immediate Family Members, or entities in
which Immediate Family Members are the owners, members or beneficiaries, as
appropriate, are the members, or (d) to a trust for the benefit of Immediate
Family Members; provided, however, that no more than a de minimus beneficial
interest in a partnership, limited liability company or trust described in (b),
(c) or (d) above may be owned by a person who is not an Immediate Family Member
or by an entity that is not beneficially owned solely by Immediate Family
Members.  "Immediate Family Members" shall be defined as the spouse and natural
or adopted children or grandchildren of the Participant and their spouses.  To
the extent that an Incentive Stock Option is permitted to be transferred during
the lifetime of the Participant, it shall be treated thereafter as a
Nonqualified Stock Option.  Any attempted assignment, transfer, pledge,
hypothecation or other disposition of Awards, or levy of attachment or similar
process upon Awards not specifically permitted herein, shall be null and void
and without effect.  The designation of a Designated Beneficiary shall not be a
violation of this Section 11(d).

          (e)  Share Certificates.  All certificates for Shares or other
securities delivered under the Plan pursuant to any Award or the exercise
thereof shall be subject to such stop transfer orders and other restrictions as
the Committee may deem advisable under the Plan or the rules, regulations, and
other requirements of the SEC, any stock exchange upon which such Shares or
other securities are then listed, and


                                     VII-7
<PAGE>
 
any applicable federal or state laws, and the Committee may cause a legend or
legends to be put on any such certificates to make appropriate reference to such
restrictions.

          (f)  No Limit on Other Compensation Arrangements.   Nothing contained
in the Plan shall prevent the Company from adopting or continuing in effect
other compensation arrangements, which may, but need not, provide for the grant
of options, stock appreciation rights and other types of Awards provided for
hereunder (subject to stockholder approval of any such arrangement if approval
is required), and such arrangements may be either generally applicable or
applicable only in specific cases.

          (g)  No Right to Employment.   The grant of an Award shall not be
construed as giving a Participant the right to be retained in the employ of the
Company or any Subsidiary or in the employ of any other entity providing
services to the Company.  The Company or any Subsidiary or any such entity may
at any time dismiss a Participant from employment, free from any liability or
any claim under the Plan, unless otherwise expressly provided in the Plan or in
any Award Agreement.   No Employee, Participant or other person shall have any
claim to be granted any Award, and there is no obligation for uniformity of
treatment of Employees, Participants or holders or beneficiaries of Awards.

          (h)  Governing Law.   The validity, construction, and effect of the
Plan, any rules and regulations relating to the Plan and any Award Agreement
shall be determined in accordance with the laws of the State of Delaware.

          (i)  Severability.  If any provision of the Plan or any Award is or
becomes or is deemed to be invalid, illegal, or unenforceable in any
jurisdiction or as to any Person or Award, or would disqualify the Plan or any
Award under any law deemed applicable by the Committee, such provision shall be
construed or deemed amended to conform to applicable laws, or if it cannot be
construed or deemed amended without, in the determination of the Committee,
materially altering the intent of the Plan or the Award, such provision shall be
stricken as to such jurisdiction, Person or Award and the remainder of the Plan
and any such Award shall remain in full force and effect.

          (j)  No Trust or Fund Created.  Neither the Plan nor any Award shall
create or be construed to create a trust or separate fund of any kind or a
fiduciary relationship between the Company and a Participant or any other
Person.  To the extent that any Person acquires a right to receive payments from
the Company pursuant to an Award, such right shall be no greater than the right
of any unsecured general creditor of the Company.

          (k)  No Fractional Shares.  No fractional Shares shall be issued or
delivered pursuant to the Plan or any Award, and the Committee shall determine
whether cash, other securities or other property shall be paid or transferred in
lieu of any fractional Shares or whether such fractional Shares or any rights
thereto shall be cancelled, terminated, or otherwise eliminated.

          (l)  Headings.  Headings are given to the subsections of the Plan
solely as a convenience to facilitate reference.   Such headings shall not be
deemed in any way material or relevant to the construction or interpretation of
the Plan or any provision thereof.


                                  SECTION 12

          Effective Date of the Plan. The Plan shall be effective as of the date
of its approval by the stockholder of the Company.


                                     VII-8
<PAGE>
 
                                  SECTION 13

          Term of the Plan.  No Award shall be granted under the Plan after the
tenth anniversary of the effective date of the Plan; however, unless otherwise
expressly provided in the Plan or in an applicable Award Agreement, any Award
theretofore granted may, and the authority of the Committee to amend, alter,
adjust, suspend, discontinue, or terminate any such Award or to waive any
conditions or rights under any such Award shall, extend beyond such date.
