                                  COMMON STOCK
 
                                  -----------
 
  McMoRan Oil & Gas Co., a Delaware corporation ("MOXY" or the "Company"), is
distributing to holders of record of shares of its common stock, par value $.01
per share (the "Common Stock"), transferable subscription rights (the "Rights")
to subscribe for and purchase additional shares of Common Stock for a price of
$3.50 per share (the "Subscription Price"). Each holder of Common Stock of
record as of the close of business on             , 1997 (the "Record Date"),
is entitled to receive [approximately 2.0] Rights for each share of Common
Stock held as of such time. The number of Rights distributed by the Company to
each record holder of Common Stock will be rounded up to the nearest whole
number and no fractional Rights or cash in lieu thereof will be distributed or
paid by the Company. Rights holders ( the "Holders") may purchase one share of
Common Stock for each Right held. Each Right also carries the right to
subscribe (the "Oversubscription Privilege") at the Subscription Price for a
pro rata portion (based on the number of Rights so exercised) of the shares of
Common Stock, if any, that are not subscribed for through the exercise of the
Rights. The offering by the Company of the shares of Common Stock purchasable
upon exercise of the Rights, including the Oversubscription Privilege, is
referred to herein as the "Rights Offering." See "The Rights Offering."
 
  On July 14, 1997, the Company entered into an agreement with Freeport-McMoRan
Resource Partners, Limited Partnership ("FRP"), a publicly traded limited
partnership of which Freeport-McMoRan Inc. ("FTX") is the administrative
managing general partner, pursuant to which, subject to completion of the
Rights Offering, MOXY will acquire the two producing oil and gas properties
(the "MCN Producing Properties") developed as part of MOXY's exploratory
drilling program with affiliates of MCN Energy Group Inc. (the "MOXY/MCN
Program") for $26 million, subject to adjustment, and repay all of the
indebtedness incurred by MOXY under the MOXY/MCN Program. The MOXY/MCN Program
will then be terminated and MOXY and FRP will enter into an aggregate $200
million multi-year exploration program (the "MOXY/FRP Exploration Program").
 
  The Company also has entered into a standby purchase agreement (the "Standby
Purchase Agreement") with FRP pursuant to which, subject to certain conditions,
FRP has provided a standby commitment (the "Standby Commitment") to purchase
for the Subscription Price all of the shares of Common Stock that are not
purchased by Holders in the Rights Offering. FRP will receive a $6 million fee
(the "Standby Fee") for the Standby Commitment, acquiring and holding the MCN
Producing Properties for resale to MOXY and entering into the MOXY/FRP
Exploration Program. FRP also has the option to purchase additional shares of
Common Stock so that if following the Rights Offering it has not acquired 30%
of the outstanding Common Stock pursuant to the Standby Commitment, it may
acquire at the Subscription Price such additional shares of Common Stock as are
necessary to provide it with up to a 30% ownership position in MOXY (the "FRP
Purchase Option").
 
  The Rights Offering, together with the Standby Commitment and FRP Purchase
Option, is part of a comprehensive plan to recapitalize the Company to enable
it to enter into the MOXY/FRP Exploration Program, purchase the MCN Producing
Properties and repay indebtedness incurred under the MOXY/MCN Program. There
can be no assurance that the Company will receive significant proceeds, if any,
from the Rights Offering. However, the Standby Purchase Agreement requires FRP
to purchase all of the shares of Common Stock that are not purchased by Holders
in the Rights Offering. If Holders do not exercise a significant number of
Rights and FRP purchases a significant number of shares of Common Stock
pursuant to the Standby Commitment or FRP Purchase Option, FRP may acquire the
power to control or significantly influence the management of the Company. See
"Risk Factors--Potential Change of Control of the Company," "Use of Proceeds"
and "Certain Relationships and Related Transactions."
 
  The Rights Offering and the Rights will expire at 5:00 p.m., New York City
time, on            , 1997 [30 days] unless extended by the Company (subject to
FRP's consent) from time to time (such date, as it may be extended, is referred
to herein as the "Expiration Date"), provided that the Expiration Date shall in
no event be later than             , 1997 [60 days]. Holders who exercise their
Rights will not be entitled to revoke their subscriptions. Holders who do not
exercise or sell their rights will relinquish any value inherent in the Rights.
Accordingly, Holders are strongly urged to exercise or sell their rights. See
"Risk Factors--Dilution."
 
  The Common Stock is traded on the Nasdaq National Market ("Nasdaq") under the
symbol "MOXY." On July 14, 1997 (the last day on which trading prices were
reported prior to the public announcement of the Rights Offering), the last
reported sales price of the Common Stock was $3 5/8 per share. It is
anticipated that the Rights will trade on Nasdaq under the symbol "MOXYR."
Certain registered broker-dealers have indicated to the Company that they
intend to make a market in the Rights. There can be no assurance, however, that
a market for the Rights will develop. Rights may also be sold in over-the-
counter and private sales transactions. Orders to sell Rights must be received
by the Subscription Agent not later than 11:00 a.m. on the third Nasdaq trading
day prior to the Expiration Date if a Holder wishes to sell Rights through the
Subscription Agent.
 
  CURRENT STOCKHOLDERS OF THE COMPANY WHO DO NOT PARTICIPATE IN THE RIGHTS
OFFERING WILL SUFFER A SUBSTANTIAL DILUTION IN THEIR RELATIVE PERCENTAGE
OWNERSHIP IN THE COMPANY UPON ISSUANCE OF COMMON STOCK TO HOLDERS EXERCISING
RIGHTS AND TO FRP.
 
  SEE "RISK FACTORS," BEGINNING ON PAGE 10, FOR A DISCUSSION OF CERTAIN FACTORS
THAT SHOULD BE CONSIDERED BY PROSPECTIVE PURCHASERS IN CONNECTION WITH AN
INVESTMENT IN THE COMMON STOCK OFFERED HEREBY.
 
 THESE SECURITIES HAVE NOT BEEN APPROVED  OR DISAPPROVED BY THE SECURITIES AND
  EXCHANGE  COMMISSION  OR  ANY  STATE SECURITIES  COMMISSION,  NOR  HAS  THE
   SECURITIES  AND EXCHANGE  COMMISSION OR ANY  STATE SECURITIES  COMMISSION
    PASSED  UPON   THE  ACCURACY  OR  ADEQUACY  OF  THIS   PROSPECTUS.  ANY
      REPRESENTATION TO THE CONTRARY IS A CRIMINAL OFFENSE.

   The following summary is qualified in its entirety by the more detailed
information and financial statements contained elsewhere in this Prospectus or
incorporated by reference herein and does not purport to be complete.  Reference
is made to, and this Prospectus Summary is qualified in its entirety by and
should be read in conjunction with, the more detailed information contained
elsewhere in this Prospectus or incorporated by reference herein.  Prospective
investors should carefully consider the information set forth under "Risk
Factors."

                                  THE COMPANY

   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 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
extensive  technical and operational expertise.

   The Rights Offering is part of a comprehensive plan to recapitalize the
Company to enable MOXY to implement an aggregate $200 million, multi-year
exploration program with FRP, to purchase the MCN Producing Properties and to
repay the indebtedness incurred by MOXY under the MOXY/MCN Program.  At a
special meeting of MOXY's stockholders on _________, 1997, MOXY's stockholders
approved the Rights Offering, the Standby Commitment, the FRP Purchase Option,
purchase of the MCN Producing Properties and the MOXY/FRP Exploration Program.
See "Business and Properties - MOXY/FRP Exploration Program" and "The Rights
Offering."

   In July 1997, FRP agreed to acquire from affiliates of MCN Energy Group Inc.
("MCN") their 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
attributable to 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,
$___ million 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 the date of completion of the Rights Offering.  The amendment also
provides that FRP will reimburse MOXY for approximately $290,000 of overhead 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 for $26.0 million, subject to the adjustments described above for
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 by it 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 subject to the MOXY/MCN Program.  See
"Business and Properties - MOXY/MCN Program" and "- MOXY/FRP Exploration
Program."

   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.  MOXY expects to continue to concentrate its efforts in selected
geographic areas where the Company's management team has significant exploration
experience.  The Company evaluates substantially all of its exploratory
prospects with 3-D seismic surveys prior to drilling.  MOXY intends to continue
to generate exploratory prospects and evaluate selected opportunities to acquire
producing oil and gas properties and to maximize its geological and geophysical

                              THE RIGHTS OFFERING

RIGHTS....................... Each holder of Common Stock will receive
                              [approximately 2.0] transferable Rights for every
                              share of Common Stock held of record as of the
                              close of business on ___________, 1997 (the
                              "Record Date"). The number of Rights distributed
                              by the Company to each Common Stock holder will be
                              rounded up to the nearest whole number. An
                              aggregate of approximately 28.6 million Rights
                              will be distributed. Each Right will be
                              exercisable for one share of Common Stock. If all
                              the Rights are exercised, an aggregate of
                              approximately 28.6 million shares of Common Stock
                              (the "Underlying Shares") will be sold upon
                              exercise of the Rights. See "The Rights Offering-
                              The Rights."

SUBSCRIPTION PRICE........... $3.50 in cash per share of Common Stock.

BASIC SUBSCRIPTION PRIVILEGE. Holders are entitled to purchase for the
                              Subscription Price one share of Common Stock for
                              each Right held (the "Basic Subscription
                              Privilege").  See "The Rights Offering -
                              Subscription Privileges - Basic Subscription
                              Privilege."

OVERSUBSCRIPTION PRIVILEGE... Each Holder who elects to exercise in full his or
                              her Basic Subscription Privilege may also
                              subscribe at the Subscription Price for additional
                              Underlying Shares available as a result of
                              unexercised Rights, if any, (the "Oversubscription
                              Privilege").  If an insufficient number of
                              Underlying Shares are available to satisfy fully
                              all exercises of the Oversubscription Privilege,
                              the available Underlying Shares will be prorated
                              among Holders who exercise their Oversubscription
                              Privilege based on the respective numbers of
                              Rights exercised by such Holders pursuant to the
                              Basic Subscription Privilege.  See "The Rights
                              Offering - Subscription Privileges -
                              Oversubscription Privilege."

EXPIRATION DATE.............. _____________, 1997, at 5:00 p.m., New York City
                              time, unless extended.  The Company may extend the

                              announce any extension by not later than 9:00
                              a.m., New York time, on the business day following

<PAGE>
 
                              Any extension of the Expiration Date will be for a
                              period of at least three Nasdaq trading days,
                              provided that the Expiration Date shall in no
                              event be later than _______, 1997. See "The Rights
                              Offering - Expiration Date."

STANDBY PURCHASE COMMITMENT.. FRP has agreed, subject to the terms and
                              conditions of the Standby Purchase Agreement, to
                              purchase at the Subscription Price all of the
                              shares of Common Stock offered hereby that are not
                              purchased by the Holders. Pursuant to the Standby
                              Purchase Agreement, FRP also has the option to
                              purchase (the "FRP Purchase Option") additional
                              shares of Common Stock so that if following the
                              Rights Offering it has not acquired 30% of the
                              outstanding Common Stock pursuant to the Standby
                              Commitment, it may acquire at the Subscription
                              Price such additional shares of Common Stock as
                              are necessary to provide it with up to a 30%
                              ownership position in MOXY.  MOXY has agreed to
                              pay FRP a fee (the "Standby Fee") of $6 million,
                              payable upon closing of the Rights Offering, for
                              providing the Standby Commitment, acquiring and
                              holding the MCN Producing Properties for resale to
                              MOXY and entering the MOXY/MCN Exploration
                              Program.  See "The Rights Offering - Standby
                              Purchase Agreement"  and "Risk Factors - Potential
                              Change of Control of the Company."

SHARES OF COMMON STOCK 
OUTSTANDING AFTER RIGHTS 
OFFERING..................... Based on the number of shares outstanding on the
                              date of this Prospectus, approximately _____
                              million  shares will be outstanding following the
                              Rights Offering (before giving effect to any
                              exercise of the FRP Purchase Option).  If all
                              Rights are exercised and the FRP Purchase Option
                              is exercised in full, approximately _____ million
                              shares of Common Stock will be outstanding.

TRANSFERABILITY OF RIGHTS.... The Rights are transferable and will be evidenced
                              by transferable subscription certificates (a
                              "Subscription Certificate").  It is anticipated
                              that they will trade on Nasdaq under the symbol
                              "MOXYR" until the close of business on the last
                              Nasdaq trading day prior to the Expiration Date.
                              Certain registered broker-dealers have indicated
                              that they intend to make a market in the Rights
                              during the period the Rights are outstanding.  No
                              assurance can be given, however, that a market for
                              the Rights will develop or, if such a market
                              develops, how long it will continue.

                              The Subscription Agent will attempt to sell Rights
                              for Holders who deliver a Subscription Certificate
                              with the instruction for sale contained on the
                              reverse side thereof properly executed to the
                              Subscription Agent no later than 11:00 a.m., New
                              York City time, on the third Nasdaq trading day
                              preceding the Expiration Date.  There can be no
                              assurance that the Subscription Agent  will be
                              able to sell any Rights or as to the price that
                              the Subscription Agent will be able to obtain if
                              it is able to effect any such

                              sale. See "The Rights Offering - Method of
                              Transferring Rights."

HOW TO EXERCISE RIGHTS....... The Basic Subscription Privilege and
                              Oversubscription Privilege may be exercised by
                              properly completing and signing the Subscription
                              Certificate and forwarding it (or following the
                              Guaranteed Delivery Procedures described below),
                              with payment of the Subscription Price for each
                              Underlying Share subscribed for pursuant to the
                              Basic Subscription Privilege and the
                              Oversubscription Privilege, to the Subscription
                              Agent on or prior to the Expiration Date.  If the
                              mail is used to forward Subscription Certificates,
                              it is recommended that insured, registered mail be
                              used.  No interest will be paid on funds delivered
                              upon exercise of the Basic Subscription Privilege
                              or the Oversubscription Privilege.  See "The
                              Rights Offering - Exercise of Rights."

                              Once a holder of Rights has exercised the Basic
                              Subscription Privilege or the Oversubscription
                              Privilege, such exercise may not be revoked.  See
                              "The Rights Offering - No Revocation."

HOW FOREIGN AND CERTAIN
OTHER STOCKHOLDERS CAN
EXERCISE RIGHTS.............. Subscription Certificates will not be mailed to
                              Holders whose addresses are outside the United
                              States or who have an APO or FPO address, but will
                              be held by the Subscription Agent for their
                              account.  To exercise such Rights, such Holders
                              must notify the Subscription Agent on or prior to
                              11:00 a.m., New York City time, on the third
                              Nasdaq trading day preceding the Expiration Date,
                              and must establish to the satisfaction of the
                              Subscription Agent that such exercise is permitted
                              under applicable law.  If such a Holder does not
                              notify the Subscription Agent and provide
                              acceptable instructions to the Subscription Agent
                              by such time, such Rights will be sold, if
                              feasible, and the net proceeds, if any, remitted
                              to such Holder.  See "The Rights Offering -
                              Foreign and Certain Other Stockholders."

WISHING TO EXERCISE RIGHTS, 
THROUGH OTHERS............... Persons holding shares of Common Stock and
                              receiving the Rights distributed with respect
                              thereto through a broker, dealer, commercial bank,
                              trust company or other nominee, as well as persons
                              holding certificates of Common Stock personally
                              who would prefer to have such institutions effect
                              transactions relating to the Rights on their
                              behalf, should contact the appropriate institution
                              or nominee and request it to effect the
                              transaction for them. See "The Rights Offering -
                              Exercise of Rights."

ISSUANCE OF COMMON STOCK..... Certificates representing shares of Common Stock
                              purchased in the Rights Offering will be delivered
                              as soon as practicable after the Expiration Date.

                                  RISK FACTORS

     Holders of the Company's Common Stock should consider carefully the
following risk factors relating to the business of MOXY and the Rights Offering,
together with the information and financial data set forth elsewhere in this
Prospectus in connection with an investment in the Common Stock offered hereby.

DISCLOSURE REGARDING FORWARD-LOOKING STATEMENTS

     This Prospectus includes "forward-looking statements" within the meaning of
Section 27A of the Securities Act and Section 21E of the Exchange Act.  All
statements other than statements of historical fact included in this Prospectus
are forward-looking statements.  Such statements include without limitation the
statements under "Prospectus Summary," "Price Range of Common Stock and Dividend
Policy," "Management's Discussion and Analysis of Financial Condition and
Results of Operations" and "Business and Properties" regarding MOXY's financial
position and liquidity, payment of dividends, its strategic alternatives, future
capital needs, exploration, development and capital expenditures (including the
amount and nature thereof), the drilling of wells, reserve estimates and future
net revenues attributable thereto, business strategies, and other plans and
objectives of management of the Company for future operations and activities.
These statements are based on certain assumptions and analyses made by the
Company in light of its experience and its perception of historical trends,
current conditions, expected future developments and other factors it believes
are appropriate under the circumstances.  Such statements are subject to risks
and uncertainties, including the risk factors discussed below, general economic
and business conditions, the business opportunities that may be presented to and
pursued by the Company, changes in laws or regulations and other factors, many
of which are beyond the control of the Company.  Although MOXY believes that the
expectations reflected in such forward-looking statements are reasonable, it can
give no assurance that such expectations will prove to have been correct.
Prospective investors are therefore cautioned that any such statements are not
guarantees of future performance and the actual results or developments may
differ materially from those projected in the forward-looking statements.
Certain important factors that could cause actual results to differ materially
from MOXY's expectations are disclosed in this Prospectus.

LIMITED OPERATING HISTORY AND SIGNIFICANT HISTORICAL OPERATING LOSSES

     The Company commenced operations in 1994.  The Company has only two
producing fields, which have been in production for only a short period of time,
making proved reserves and levels of future production attributable to these
fields less susceptible to estimation than fields with longer production
histories.  As a result of the Company's exploratory drilling, the Company has
incurred significant operating losses to date.  The Company's future viability
must be considered in light of the risks and difficulties frequently encountered
by companies engaged in the early stages of oil and gas exploration, development
and production activities.

     The development of the Company's business will continue to require
substantial expenditures.  The Company's future financial results will depend
primarily on its ability to locate hydrocarbons in commercial quantities and on
the market prices for oil and gas.  There can be no assurance that the Company
will achieve or sustain profitability or positive cash flows from future
operating activities.

DETERMINATION OF SUBSCRIPTION PRICE AND MARKET CONSIDERATIONS

     The Subscription Price was determined by negotiation between the Company
and FRP.  The Subscription Price does not necessarily bear any relationship to
the book value of the Company's assets, past operations, cash flow, earnings,
financial condition or any other established criteria for value and should not
be considered an indication of the underlying values of the Company.  The market
price of the Common Stock could be subject to significant fluctuations in
response to MOXY's operating results and other factors, including the size of
the public float of the Common Stock (which will depend, in part, on the
percentage of the Rights that are exercised by Holders) after the Rights
Offering.  See "The Rights Offering - Determination of Subscription Price."

                                      -10-
<PAGE>
 
     There is currently no public market for the Rights.  Although MOXY has been
advised by certain broker-dealers that they intend to make a market in the
Rights, they are under no obligation to do so, and any market making activity
may be discontinued at any time.  Although the Rights will be transferable and
listed on Nasdaq, there can be no assurance that the Rights will have any
economic value or that a public market for the Rights will develop or be
sustained.  There also can be no assurance that, following the issuance of the
Rights and of the Underlying Shares upon exercise of Rights, a subscribing
Holder will be able to sell shares of Common Stock purchased in the Rights
Offering at a price equal to or greater than the Subscription Price.

POTENTIAL CHANGE OF CONTROL OF THE COMPANY

     If FRP acquires a significant number of shares of Common Stock pursuant to
the Standby Commitment or the FRP Purchase Option, it will have the power to
control or significantly influence the election of directors and all other
matters submitted to the Company's stockholders and otherwise to direct the
business and affairs of the Company.  If less than approximately 25% of the
Rights are exercised by the Holders, then pursuant to the Standby Commitment FRP
will acquire a majority of the outstanding Common Stock and will have the power
to control MOXY.  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 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.  If FRP acquires a
majority of the outstanding shares of Common Stock as a result of the Standby
Commitment, it will be in a position to control the election of all of the
Company's directors and to otherwise direct the business and affairs of the
Company.  MOXY and FRP have agreed to adhere to the policies described under the
heading "Description of Capital Stock - Stockholder Agreement and Registration
Rights" at any time that FRP owns more than 10% of the outstanding Common Stock.
See "The Rights Offering - Standby Purchase Agreement" and "Certain
Relationships and Related Transactions - MCN Properties; Standby Purchase
Agreement."

IRREVOCABILITY OF SUBSCRIPTIONS

     The election to exercise Rights is irrevocable.  Until certificates
representing shares of Common Stock are delivered, subscribing Holders may not
be able to sell such shares.  Certificates representing shares of Common Stock
purchased in the Rights Offering will be delivered by mail as soon as
practicable following the Expiration Date.  No interest will be paid to Holders
on funds delivered to the Subscription Agent pursuant to the exercise of Rights
pending delivery of such certificates.  See "The Rights Offering - Subscription
Privileges," "- Exercise of Rights" and "- No Revocation."

DILUTION

     Stockholders who do not exercise their Rights will experience a significant
decrease in their proportionate interest in the equity ownership and voting
power of the Company.  The sale of the Rights may not compensate a stockholder
for all or any part of any reduction in the market value of such stockholder's
Common Stock resulting from the Rights Offering.  Stockholders who do not
exercise or sell their rights will relinquish any value inherent in the Rights.

     After giving effect to the exercise of the Rights and the Standby
Commitment (and assuming no exercise of the FRP Purchase Option or other
issuances of Common Stock), the Company will have approximately _____ million
shares of Common Stock issued and outstanding, as compared with approximately
14.1 million shares of Common Stock issued and outstanding as of the date of
this Prospectus.  If all Rights are exercised and the FRP Purchase Option is
exercised in full, approximately _____ million shares of Common Stock will be
outstanding.

     Purchasers of Common Stock in the Rights Offering will experience immediate
and substantial dilution in the net tangible book value per share attributable
to such shares of Common Stock.  See "Dilution."

DEPENDENCE ON MANAGEMENT AND ADMINISTRATIVE SERVICES

     The Company depends upon certain management and administrative services
provided by FM Services Company ("FMS"), a corporation 50% owned by each of FTX
and Freeport-McMoRan Copper & Gold Inc. ("FCX"), pursuant to a Services
Agreement (the "Services Agreement") to manage and support certain of its
operations.  The Services Agreement does not assure the Company unlimited access
to all of the executive officers listed under "Management," and there will be
competition between the Company, FTX, FRP, FCX and their respective affiliates
for the time and effort of the employees of FMS who provide services to the
Company.  If the Company were deprived of adequate access to certain key members
of its management team or other personnel, or lost access to such services
altogether, the Company's results of operations could be materially and
adversely affected.  See "Certain Relationships and Related Transactions -
Services Agreement."

CONFLICTS OF INTEREST

     FRP, through its subsidiaries and joint venture operations, is one of the
world's leading integrated phosphate fertilizer producers.  FRP also produces
oil and gas in connection with the sulphur mining operations at its Main Pass
complex offshore Louisiana.  FTX is the administrative managing general partner
of FRP.  In addition to the Services Agreement, the Company is a party to other
material contracts with FTX, FRP and their affiliates.  See "Certain
Relationships and Related Transactions."  The Company may also enter into
additional material transactions and agreements with FTX and FRP and their
affiliates after the date of this Prospectus.  It is the Company's policy to
enter into any transaction with a related party on terms that, on the whole, are
no less favorable than those that would be available from unaffiliated parties.
Based on the Company's experience in the industry and the terms of its
transactions with unaffiliated parties, it is the Company's belief that all of
its transactions with related parties met that standard at the time such
transactions were effected.  However, because the Company has not and does not
intend to seek competitive bids for such services, it is possible that the terms
of certain transactions with affiliates may be more or less favorable to MOXY
than they would be if the transactions were among unrelated parties.  In
addition, certain officers and directors of the Company are also officers,
directors and/or stockholders of FTX, FRP and FCX, and it is possible that
conflicts of interest could arise as a result thereof.  See "Management."
Conflicts of interest could arise, for example, if either the Company or FRP
were presented with the opportunity to engage in a business competing with the
other or if the Company and FRP were to enter into a business relationship
together.  See "Description of Capital Stock - Stockholder Agreement and
Registration Rights" for a description of the policies to be followed by the
Company following the consummation of the Rights Offering for transactions with
FRP and its affiliates.  It is possible that conflicts of interest arising from
any such transactions may be resolved in a manner that is not favorable to the
Company.

VOLATILITY OF OIL AND GAS PRICES

     The Company's revenues depend substantially on the prevailing prices for
natural gas and, to a lesser extent, oil.  In recent years, natural gas and oil
prices and, therefore, the level of drilling, exploration, development and
production, have been extremely volatile.  Prices are affected by supply and
demand as well as actions of state and local agencies, U.S. and foreign
governments and international cartels.  All of these factors are beyond the
control of the Company.  Any significant or extended decline in natural gas and
oil prices will have a material adverse effect on the Company's financial
condition and operations and could impair its access to capital.

EXPLORATION AND DEVELOPMENT RISKS

     Exploration and development of natural gas and oil involves a high degree
of risk that no commercial production will be obtained or that the production
will be insufficient to recover drilling and completion costs.  The cost of
drilling, completing and operating wells is often uncertain, and cost overruns
in exploration and development operations can adversely affect the economics of
a project.  The Company's drilling operations may be curtailed, delayed or
canceled as a result of numerous factors, including title problems, equipment
failures, weather conditions, marine accidents, fires and explosions, compliance
with governmental 

                                      -12-
<PAGE>
 
requirements and shortages or delays in the delivery of equipment. Furthermore,
completion of a well does not ensure a profit on the investment or a recovery of
drilling, completion and operating costs.

SUBSTANTIAL CAPITAL REQUIREMENTS

     The Company makes, and will continue to make, substantial capital
expenditures for the exploration, development, and production of oil and natural
gas reserves and related projects.  If the Company fails to discover significant
reserves, experiences operating difficulties or if oil and gas prices decline
and reduce cash generated from operations, the Company may be required to obtain
additional financing to fund its operations.  No assurance can be given that
such financing will be available, and if it is not available, the Company may be
required to curtail its operations.

REPLACEMENT OF RESERVES

     MOXY's future performance depends in part upon its ability to acquire
mineral leases and to find and develop oil and gas reserves that are
economically recoverable.  Without successful exploration or development
activities, MOXY's reserves will decline.  No assurance can be given that MOXY
will be able to find and develop additional reserves on an economic basis.

     MOXY's business is capital intensive, and significant operating cash flow
must be reinvested in development and exploration activities in order for MOXY
to maintain and increase its asset base of proved oil and gas reserves.  To the
extent that cash flow from operations is reduced and external sources of capital
become limited or unavailable, MOXY's ability to make the necessary capital
investments to maintain or expand its asset base would be impaired.  See "-
Substantial Capital Requirements."  Without such investment, MOXY's oil and gas
reserves would decline.  For a discussion of MOXY's reserves, see "Business and
Properties - Oil and Gas Reserves."

PURCHASE OF RESERVES

     Although the Company currently emphasizes reserve growth through
exploratory drilling, it may make acquisitions from time to time of producing
properties and properties with proved undeveloped reserves.  Evaluation of
recoverable reserves of natural gas and oil, which is an integral part of the
property selection process, depends on evaluation of geological, engineering and
production data, some or all of which may prove to be unreliable or not
indicative of future performance.  See "-- Reserves and Future Net Cash Flow."

RESERVES AND FUTURE NET CASH FLOW

     Information relating to proved oil and gas reserves owned by MOXY and those
attributable to the MCN Producing Properties is based upon engineering
estimates.  Reserve engineering is a subjective process of estimating the
recovery from underground accumulations of oil and natural gas that cannot be
measured in an exact manner, and the accuracy of any reserve estimate is a
function of the quality of available data and of engineering and geological
interpretation and judgment.  Estimates of economically recoverable oil and gas
reserves and of future net cash flows necessarily depend upon a number of
variable factors and assumptions, such as historical production from the area
compared with production from other producing areas, the assumed effects of
governmental regulations and assumptions concerning future oil and gas prices,
future operating costs, severance and excise taxes, development costs and
workover and remedial costs, all of which may vary considerably from actual
results.  Because all reserve estimates are to some degree speculative, the
quantities of oil and natural gas that are ultimately recovered, production and
operating costs, the amount and timing of future development expenditures and
future oil and natural gas sales prices may all vary from those assumed in these
estimates and such variances may be material.  In addition, different reserve
engineers may make different estimates of reserve quantities and cash flows
based on the same  data.  See "Business and Properties - Oil and Gas Reserves."

     The present values of estimated future net cash flows referred to in this
Prospectus should not be construed as the current market value of the estimated
proved oil and gas reserves attributable to MOXY's 

                                      -13-
<PAGE>
 
properties or of the MCN Producing Properties. In accordance with applicable
requirements of the Commission, the estimated discounted future net cash flows
from proved reserves are generally based on prices and costs as of the date of
the estimate, while actual future prices and costs may be materially higher or
lower. Actual net cash flows also will be affected by factors such as the amount
and timing of production, supply and demand for oil and gas, curtailments or
increases in consumption by gas purchasers and changes in governmental
regulations and taxation. The timing of future net cash flows from proved
reserves, and thus their actual present value, will be affected by the timing of
production and the incurrence of expenses incurred in the development and
production of oil and gas properties. In addition, the 10% discount factor,
which is required by the Commission to be used to calculate discounted future
net cash flows for reporting purposes, is not necessarily the most appropriate
discount factor based on interest rates in effect from time to time and risks
associated with the oil and gas properties owned by MOXY, the MCN Producing
Properties or the oil and gas industry in general.

OPERATING HAZARDS; LIMITED INSURANCE COVERAGE

     MOXY's operations are subject to hazards and risks inherent in drilling
for, producing and transporting natural gas and oil, such as fires, explosions,
natural disasters, encountering formations with abnormal pressures, mechanical
problems,  blowouts, cratering, pipeline ruptures and spills, any of which can
result in environmental pollution, personal injuries, property damage and
substantial losses to MOXY.  Moreover, MOXY's offshore operations in the Gulf
are subject to a variety of operating risks peculiar to the marine environment,
such as hurricanes and other adverse weather conditions, more extensive
governmental regulation (including regulations that may, in certain
circumstances, impose strict liability for pollution damage) and interruption or
termination of operations by governmental authorities based on environmental or
other considerations.

     MOXY maintains insurance coverage against some, but not all, potential
losses.  MOXY's coverages include, but are not limited to, operator's extra
expense, physical damage on certain assets, employer's liability, comprehensive
general liability, automobile, workers' compensation and loss of production
income insurance, and limited coverage for sudden environmental damages.  MOXY
does not believe that insurance coverage is available at a reasonable cost for
environmental damages that occur over time or the full potential liability that
could be caused by sudden environmental damages.  Accordingly, MOXY may be
subject to material uninsured liabilities or may lose substantial portions of
its properties in the event of environmental damages.  The occurrence of an
event that is not fully covered by insurance could have a material adverse
effect on MOXY's financial condition and results of operations.  See "Business
and Properties - Operating Hazards and Insurance."

GOVERNMENTAL REGULATION

     General.  MOXY's operations are affected by political developments and
federal and state laws and regulations.  In particular, oil and natural gas
production, operations and economics are or have been affected by price
controls, taxes and other laws relating to the oil and natural gas industry, by
changes in such laws and by changes in administrative regulations.  MOXY cannot
predict how existing laws and regulations may be interpreted by enforcement
agencies or court rulings, whether additional laws and regulations will be
adopted, or the effect such changes may have on its business or financial
condition.  See "Business and Properties - Regulation."

     Environmental.  MOXY's operations are subject to numerous laws and
regulations governing the discharge of materials into the environment or
otherwise relating to environmental protection.  These laws and regulations
require the acquisition of a permit before drilling commences, restrict the
types, quantities and concentration of various substances that can be released
into the environment in connection with drilling and production, limit or
prohibit drilling on certain lands lying within wilderness, wetland and other
protected areas, and impose substantial liabilities for pollution that could
result from MOXY's operations.  Moreover, the recent trend toward stricter
standards in environmental legislation and regulation is likely to continue.
For instance, legislation has been proposed in Congress from time to time that
would reclassify certain crude oil and natural gas exploration and production
wastes as "hazardous wastes" which would make the wastes subject to much 

                                      -14-
<PAGE>
 
more stringent handling, disposal and clean-up requirements. If such legislation
were to be enacted, it could have a significant impact on MOXY's operating
costs, as well as the oil and gas industry in general. Initiatives to further
regulate the disposal of crude oil and natural gas wastes are also pending in
certain states and could have a similar impact. MOXY could incur substantial
costs to comply with environmental laws and regulations. In addition to
compliance costs, government entities and other third parties may assert
substantial liabilities against owners and operators of oil and gas properties
for oil spills, discharges of hazardous materials, remediation and clean-up
costs and other environmental damages, including damages caused by previous
property owners. The imposition of any such liabilities on MOXY could have a
material adverse effect on MOXY's financial condition and results of operations.

     The Oil Pollution Act of 1990 imposes a variety of regulations on
"responsible parties" related to the prevention of oil spills.  The
implementation of new, or the modification of existing, environmental laws or
regulations, including regulations promulgated pursuant to the Oil Pollution Act
of 1990, could have a material adverse impact on MOXY.  See "Business and
Properties - Regulation - Environmental."

SHORTAGES OF SUPPLIES AND EQUIPMENT

     The Company's ability to conduct its operations in a timely and cost
effective manner is subject to the availability of oil and gas field supplies,
equipment and service crews.  The industry is currently experiencing a shortage
of certain types of drilling rigs and work boats in the Gulf of Mexico.  This
shortage could result in delays in the Company's operations as well as higher
operating and capital costs.  Shortages of other drilling equipment, tubular
goods, drilling service crews and seismic crews may occur from time to time,
further hindering the Company's ability to conduct its operations as planned.

COMPETITION

     MOXY operates in the highly competitive areas of oil and natural gas
production, development and exploration with many other companies, many of which
have significantly greater financial and other resources than MOXY.  Factors
affecting MOXY's ability to compete effectively include the availability of
capital, access to information relating to a property, the standards established
by MOXY for the minimum projected return on investment and the intermediate
transportation of gas.  MOXY's competitors include major integrated oil
companies and a substantial number of independent energy companies, many of
which may have substantially larger financial resources, staffs and facilities
than MOXY.  See "Business and Properties - Competition."


                                USE OF PROCEEDS

     The net proceeds from the Rights Offering 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, to 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.  See "Business and Properties - MOXY/MCN Program" and "--
MOXY/FRP Exploration Program."


                              THE RIGHTS OFFERING

THE RIGHTS

     MOXY is distributing transferable Rights at no cost to the record holders
of shares of its outstanding Common Stock as of the close of business on the
Record Date. MOXY will distribute [approximately 2.0] Rights for each share of
Common Stock held on the Record Date.  An aggregate of approximately 28.6
million 

                                      -15-
<PAGE>
 
Rights exercisable to purchase an aggregate of approximately 28.6 million shares
of Common Stock are being distributed in connection with the Rights Offering.
The Rights will be evidenced by transferable Subscription Certificates. Each
Right will entitle the Holder to purchase one share of Common Stock upon the
payment of the Subscription Price ($3.50 in cash). There can be no assurance
that the Common Stock will trade at prices above the Subscription Price. See
"Risk Factors - Determination of Subscription Price and Market Considerations."

     No fractional Rights or cash in lieu thereof will be issued or paid. The
number of Rights distributed to each stockholder will be rounded up to the
nearest whole number of Rights.  No Subscription Certificate may be divided in
such a way as to permit the Holder of such Subscription Certificate to receive a
greater number of Rights than the number to which such Subscription Certificate
entitles its Holder, except that a depository, bank, trust company or securities
broker or dealer holding shares of Common Stock on the Record Date for more than
one beneficial owner may, upon proper showing to the Subscription Agent,
exchange its Subscription Certificate to obtain a Subscription Certificate for
the number of Rights to which all such beneficial owners in the aggregate would
have been entitled had each been a record holder of Common Stock on the Record
Date.  MOXY reserves the right to refuse to issue any such Subscription
Certificate if such issuance would be inconsistent with the principle that each
beneficial owner's holdings will be rounded up to the nearest whole Right.

     Because the number of Rights distributed to each record holder will be
rounded up to the nearest whole number, beneficial owners of Common Stock who
are also the record holders of such shares will receive more Rights under
certain circumstances than beneficial owners of Common Stock who are not the
record holders of their shares and who do not obtain (or cause the record holder
of their shares to obtain) a separate Subscription Certificate with respect to
the shares of Common Stock beneficially owned by them, including shares held in
an investment advisory or similar account.  To the extent that record holders or
beneficial owners of Common Stock who obtain a separate Subscription Certificate
receive more Rights, they will be able to subscribe for more shares of Common
Stock pursuant to the Basic Subscription Privilege.

     The issuance by MOXY of shares of Common Stock pursuant to the Rights
Offering is not conditioned upon the subscription of any minimum number of
shares of Common Stock by holders of the Rights.  See "The Rights Offering -
Subscription Privileges -- Oversubscription Privilege."

     BEFORE EXERCISING OR SELLING ANY RIGHTS, POTENTIAL INVESTORS ARE URGED TO
READ CAREFULLY THE INFORMATION SET FORTH UNDER "RISK FACTORS."

EXPIRATION DATE

     The Rights Offering and the Rights will expire on the Expiration Date
(_______, 1997) at 5:00 p.m., New York City time, unless extended.  The Company
may, with FRP's consent, extend the Expiration Date and will announce any
extensions 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 later than ______________, 1997.  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.  MOXY will not be obligated to honor any purported exercise of Rights
received by the Subscription Agent after the Expiration Date, regardless of when
the documents relating to such exercise were sent, except pursuant to the
guaranteed delivery procedures described below.

SUBSCRIPTION PRIVILEGES

     BASIC SUBSCRIPTION PRIVILEGE.  Each Right will entitle the holder thereof
to receive, upon payment of the Subscription Price, one share of Common Stock.
To exercise the Basic Subscription Privilege, Rights holders must pay the
Subscription Price in full and fully comply with the instructions set forth
below under the heading "-- Exercise of Rights."  Certificates representing
shares of Common Stock purchased pursuant to the Basic Subscription Privilege
will be delivered to subscribers as soon as practicable after the Expiration
Date.

                                      -16-
<PAGE>
 
     OVERSUBSCRIPTION PRIVILEGE.  Subject to the allocation procedure described
below, each Right also carries 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
(the "Excess Shares").  Only Holders who exercise the Basic Subscription
Privilege in full will be entitled to exercise the Oversubscription Privilege.
The Oversubscription Privilege must be exercised at the same time as the Basic
Subscription Privilege is exercised by paying the Subscription Price of the
Excess Shares in full and by properly complying with the instructions set forth
below under the heading "-- Exercise of Rights."   Holders who intend to
subscribe for additional shares of Common Stock through the Oversubscription
Privilege so that after the Rights Offering they may own 15% or more of the
outstanding shares of Common Stock should be aware of the terms of the Company's
Preferred Rights Agreement.  See "Description of Capital Stock - Preferred Stock
Purchase Rights."  Certificates representing Excess Shares purchased pursuant to
the Oversubscription Privilege will be delivered to subscribers as soon as
practicable after the Expiration Date and after all prorations and adjustments
contemplated by the terms of the Rights Offering have been effected.

     Only Excess Shares not subscribed for through the Basic Subscription
Privilege will be available for purchase pursuant to the Oversubscription
Privilege.  If the Excess Shares are not sufficient to satisfy all subscriptions
pursuant to the Oversubscription Privilege, the Excess Shares will be allocated
pro rata (subject to the elimination of fractional shares) among those Holders
exercising the Oversubscription Privilege in proportion to the number of shares
each Holder subscribed for pursuant to the Basic Subscription Privilege;
provided, however, that if such pro rata allocation results in any Holder being
allocated a greater number of Excess Shares than such Holder subscribed for
pursuant to the exercise of such Holder's Oversubscription Privilege, then such
Holder will be allocated only such number of Excess Shares as such Holder
subscribed for, and the remaining Excess Shares will be allocated among all
other Holders exercising the Oversubscription Privilege.

STANDBY PURCHASE AGREEMENT

     MOXY and FRP have entered into a 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 to purchase additional shares of Common Stock so that if
following the Rights Offering it has not acquired 30% of the outstanding Common
Stock pursuant to the Standby Commitment, it may acquire at the Subscription
Price such additional shares of Common Stock as are necessary to provide it with
up to a 30% ownership position in MOXY.  MOXY has also agreed to pay the Standby
Fee to FRP upon the closing of the Standby Commitment.  The rights and
obligations of the Company 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.  See "Certain Relationships and Related Transactions
- - MCN Properties; Standby Purchase Agreement."

     MOXY and FRP also will enter into a Stockholder Agreement (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 Purchase Agreement.  If FRP acquires a
majority of the outstanding shares of Common Stock as a result of the Standby
Commitment, it will be in a position to control the election of all of the
Company's directors and to otherwise direct the business and affairs of the
Company.  If FRP acquires less than a majority of the outstanding shares of
Common Stock, but acquires a significant number of shares through the Standby
Commitment or the FRP Purchase Option, it will have the ability to significantly
influence the management and control of the Company.  See "Risk Factors -
Potential Change of Control of the Company."  The Stockholder Agreement provides
that the Company will not, without the approval of a committee composed of
independent members of the Board of Directors, take certain actions, including,
among other things, purchases of Common Stock and certain transactions with FRP
involving aggregate payments in excess of $5 million.  Moreover, the Company
intends 

                                      -17-
<PAGE>
 
to conduct all such transactions on an arms'-length basis. However, there can be
no assurance that the actions taken by the Company will always be in the best
interests of public stockholders. See "Certain Relationships and Related
Transactions - MCN Properties; Standby Purchase Agreement" and "Description of
Capital Stock - Stockholder Agreement and Registration Rights."

DETERMINATION OF SUBSCRIPTION PRICE

     The Subscription Price was determined by negotiations between the Company
and FRP.  The Company's objective in establishing the Subscription Price was to
approximate recent trading prices, 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 an involuntary dilution of their ownership
and voting percentage in the Company.  In approving the Subscription Price, the
Board of Directors considered such factors as the alternatives available to MOXY
for raising capital, the market price of the Common Stock, the pro rata nature
of the offering, pricing of similar transactions, the business prospects for
MOXY and the general condition of the securities markets.  There can be no
assurance, however, that the market price of the Common Stock will not decline
during the subscription period or that, following the issuance of the Rights and
of the Underlying Shares upon exercise of Rights, a subscribing Holder will be
able to sell the Rights or sell the Underlying Shares purchased in the Rights
Offering at a price equal to or greater than the Subscription Price.

EXERCISE OF RIGHTS

     Rights may be exercised by delivery to the Subscription Agent, on or prior
to the Expiration Date, of the properly completed and duly executed Subscription
Certificate evidencing such Rights (together with any required signature
guarantees), accompanied by payment in full of the Subscription Price for each
Underlying Share subscribed for pursuant to the Basic Subscription Privilege and
the Oversubscription Privilege.  All payments must be made by (i) check or bank
draft drawn upon a United States bank or postal, telegraphic or express money
order payable to "ChaseMellon Shareholder Services, L.L.C., as Subscription
Agent," or (ii) wire transfer of same-day funds to the account maintained by the
Subscription Agent for such purpose at Mellon Bank, Pittsburgh, PA, Account No.
Reorg Acct 100-2331 (MOXY subscription), ABA No. 043 000 261 Attn:  ChaseMellon
Shareholder Services, Evelyn O'Connor (201) 296-4515.  Payment of the
Subscription Price will be deemed to have been received by the Subscription
Agent only upon (a) clearance of any uncertified check, (b) receipt by the
Subscription Agent of any certified check or bank draft drawn upon a U.S.  bank
or of any postal, telegraphic or express money order, or (c) receipt of good
funds in the Subscription Agent's account designated above.  PLEASE NOTE THAT
FUNDS PAID BY UNCERTIFIED PERSONAL CHECK MAY TAKE AT LEAST FIVE BUSINESS DAYS TO
CLEAR.  ACCORDINGLY, HOLDERS WHO WISH TO PAY THE SUBSCRIPTION PRICE BY MEANS OF
UNCERTIFIED PERSONAL CHECK ARE URGED TO MAKE PAYMENT SUFFICIENTLY IN ADVANCE OF
THE EXPIRATION DATE TO ENSURE THAT SUCH PAYMENT IS RECEIVED AND CLEARED BY SUCH
DATE, AND ARE URGED TO CONSIDER PAYMENT BY MEANS OF CERTIFIED OR CASHIER'S
CHECK, MONEY ORDER OR WIRE TRANSFER OF FUNDS.

     If a Holder wishes to exercise Rights, but time will not permit such Holder
to cause the Subscription Certificate(s) evidencing such Rights to reach the
Subscription Agent on or prior to the Expiration Date, such Rights may
nevertheless be exercised if all of the following conditions (the "Guaranteed
Delivery Procedures") are met:

     (i)      such Holder has caused payment in full of the Subscription Price
     for each Underlying Share being subscribed for pursuant to the Basic
     Subscription Privilege and the Oversubscription Privilege to be received
     (in the manner set forth above) by the Subscription Agent on or prior to
     the Expiration Date;

     (ii)     the Subscription Agent receives, on or prior to the Expiration
     Date, a notice of guaranteed delivery (a "Notice of Guaranteed Delivery"),
     substantially in the form provided with the Instructions as to Use of
     Subscription Certificates (the "Instructions") distributed with the
     Subscription Certificates, from a member firm of a registered national
     securities exchange, a member of the National Association of Securities
     Dealers, Inc., a commercial bank or trust company having an office or
     correspondent in the United States, or a member in good standing of a
     recognized signature guarantee medallion program, pursuant to Rule 17Ad-15
     of the Exchange Act (each, an "Eligible Institution"), stating the name of
     the exercising Holder, the number of Rights represented by the Subscription
     Certificate(s) held by such exercising Holder, the number of Underlying
     Shares being subscribed for pursuant to the Basic Subscription Privilege
     and the number of Underlying Shares, if any, being subscribed for pursuant
     to the Oversubscription Privilege, and guaranteeing the delivery to the
     Subscription Agent of any Subscription Certificate(s) evidencing such
     Rights within three Nasdaq trading days following the date of the Notice of
     Guaranteed Delivery; and

     (iii)     the properly completed and duly executed Subscription
     Certificate(s), including any required signature guarantees, evidencing the
     Rights being exercised is received by the Subscription Agent within three
     Nasdaq trading days following the date of the Notice of Guaranteed Delivery
     relating thereto.  The Notice of Guaranteed Delivery may be delivered to
     the Subscription Agent in the same manner as Subscription Certificates at
     the addresses set forth above, or may be transmitted to the Subscription
     Agent by facsimile transmission (facsimile no.  (201) 329-8926).
     Additional copies of the form of Notice of Guaranteed Delivery are
     available upon request from the Information Agent whose address and
     telephone numbers are set forth under "-- Information Agent."

     Unless a Subscription Certificate (i) provides that the shares of Common
Stock to be issued pursuant to the exercise of Rights represented thereby are to
be delivered to the record holder of such Rights or (ii) is submitted for the
account of an Eligible Institution, signatures on such Subscription Certificate
must be guaranteed by an Eligible Institution subject to the standards and
procedures adopted by the Subscription Agent.

     Funds received in payment of the Subscription Price for Excess Shares
subscribed for pursuant to the Oversubscription Privilege will be held in a
segregated account pending issuance of such Excess Shares.  If a Rights holder
exercising the Oversubscription Privilege is allocated less than all of the
Excess Shares that such holder wished to subscribe for pursuant to the
Oversubscription Privilege, the excess funds paid by such holder in respect of
the Subscription Price for shares not issued will be returned by mail without
interest or 

                                      -19-

deduction as soon as practicable after the Expiration Date and after all
prorations and adjustments contemplated by the terms of the Rights Offering have
been effected.

     A Holder who holds shares of Common Stock for the account of others, such
as a broker, a trustee or a depositary for securities, should notify the
respective beneficial owners of such shares as soon as possible to ascertain
such beneficial owners' intentions and to obtain instructions with respect to
the Rights beneficially owned by them.  Beneficial owners of Common Stock or
Rights held through such a holder of record should contact the holder and
request the holder to effect transactions in accordance with the beneficial
owner's instructions.  If a beneficial owner wishes to obtain a separate
Subscription Certificate, he should contact the nominee as soon as possible and
request that a separate Subscription Certificate be issued.  A nominee may
request that any Subscription Certificate held by it be split into such smaller
denominations as it wishes, provided that the Subscription Certificate is
received by the Subscription Agent, properly endorsed, no later than 5:00 p.m.,
New York City time, on __________, 1997.

     If either the number of Rights being exercised is not specified on a
Subscription Certificate, or the payment delivered is not sufficient to pay the
full aggregate Subscription Price for all Underlying Shares stated to be
subscribed for, the Holder will be deemed to have exercised the maximum number
of Rights that could be exercised for the amount of the payment delivered by
such Holder.  If the payment delivered by the Holder exceeds the aggregate
Subscription Price for the number of Rights evidenced by the Subscription
Certificate(s) delivered by such Holder, the payment will be applied, until
depleted, to subscribe for Underlying Shares in the following order: (i) to
subscribe for the number of Underlying Shares indicated on the Subscription
Certificate(s) pursuant to the Basic Subscription Privilege; (ii) to subscribe
for Underlying Shares until the Basic Subscription Privilege has been fully
exercised with respect to all of the Rights represented by the Subscription
Certificate; and (iii) to subscribe for additional Underlying Shares pursuant to
the Oversubscription Privilege (subject to any applicable proration).  Any
excess payment remaining after the foregoing allocation will be returned to the
Holder as soon as practicable by mail, without interest or deduction.

     The Instructions accompanying the Subscription Certificates should be read
carefully and followed in detail.  PLEASE DO NOT SEND SUBSCRIPTION CERTIFICATES
TO MOXY.

     THE METHOD OF DELIVERY OF SUBSCRIPTION CERTIFICATES AND PAYMENT OF THE
SUBSCRIPTION PRICE TO THE SUBSCRIPTION AGENT WILL BE AT THE ELECTION AND RISK OF
THE HOLDERS, BUT IF SENT BY MAIL IT IS RECOMMENDED THAT SUCH CERTIFICATES AND
PAYMENTS BE SENT BY REGISTERED MAIL, PROPERLY INSURED, WITH RETURN RECEIPT
REQUESTED, AND THAT A SUFFICIENT NUMBER OF DAYS BE ALLOWED TO ENSURE DELIVERY TO
THE SUBSCRIPTION AGENT AND CLEARANCE OF PAYMENT PRIOR TO THE EXPIRATION DATE.
BECAUSE UNCERTIFIED PERSONAL CHECKS MAY TAKE AT LEAST FIVE BUSINESS DAYS TO
CLEAR, HOLDERS ARE STRONGLY URGED TO PAY, OR ARRANGE FOR PAYMENT, BY MEANS OF
CERTIFIED OR CASHIER'S CHECK, MONEY ORDER OR WIRE TRANSFER OF FUNDS.

     All questions concerning the timeliness, validity, form and eligibility of
any exercise of Rights will be determined by MOXY, whose determinations will be
final and binding.  MOXY, in its sole discretion, may waive any defect or
irregularity, or permit a defect or irregularity to be corrected within such
time as it may determine, or reject the purported exercise of any Right by
reason of any defect or irregularity in such exercise.  Subscriptions will not
be deemed to have been received or accepted until all irregularities have been
waived or cured within such time as MOXY determines in its sole discretion.
Neither MOXY nor the Subscription Agent will be under any duty to give
notification of any defect or irregularity in connection with the submission of
Subscription Certificates or incur any liability for failure to give such
notification.

     Any questions or requests for assistance concerning the method of
exercising Rights or requests for additional copies of this Prospectus, the
Instructions or the Notice of Guaranteed Delivery should be directed to the
Information Agent whose address and telephone numbers are set forth under "--
Information Agent."

NO REVOCATION

     ONCE A HOLDER HAS EXERCISED THE BASIC SUBSCRIPTION PRIVILEGE OR THE
OVERSUBSCRIPTION PRIVILEGE, SUCH EXERCISE MAY NOT BE REVOKED BY SUCH HOLDER.

METHOD OF TRANSFERRING RIGHTS

     Rights may be purchased or sold through usual investment channels,
including banks and brokers.  It is anticipated that the Rights will trade on
Nasdaq under the symbol "MOXYR."  Rights also may be sold in over-the-counter
and private sales transactions.  Certain registered broker-dealers have
indicated that they intend to make a market in the Rights during the period the
Rights are outstanding.  However, there can be no assurance that a trading
market for the Rights will develop or, if such a market develops, as to how long
it will continue.

     The Rights evidenced by a single Subscription Certificate may be
transferred in whole by endorsing the Subscription Certificate for transfer in
accordance with the instructions included thereon.  A portion of the Rights
evidenced by a single Subscription Certificate (but not fractional Rights) may
be transferred by delivering to the Subscription Agent a Subscription
Certificate properly endorsed for transfer, with instructions to register such
portion of the Rights evidenced thereby in the name of the transferee (and to
issue a new Subscription Certificate to the transferee evidencing such
transferred Rights).  In such event, a new Subscription Certificate evidencing
the balance of the Rights will be issued to the Holder or, if the Holder so
instructs, to an additional transferee. A signature guarantee must be provided
by an Eligible Institution.

     The Rights evidenced by a Subscription Certificate also may be sold, in
whole or in part, through the Subscription Agent by delivering to the
Subscription Agent such Subscription Certificate properly executed for sale by
the Subscription Agent.  If only a portion of the Rights evidenced by a single
Subscription Certificate is to be sold by the Subscription Agent, such
Subscription Certificate must be accompanied by instructions setting forth the
action to be taken with respect to the Rights that are not to be sold.  If the
Rights can be sold, sales of such Rights will be deemed to have been effected at
the weighted average price received by the Subscription Agent for all Rights
sold by it on the day such Rights are sold, less any applicable brokerage
commissions, taxes and other direct expenses of sale.  Promptly following the
settlement of any such sale, the Subscription Agent will send the Holder a check
for the net proceeds (after deduction of any applicable brokerage commissions,
taxes and other direct expenses of the sale) from the sale of any Rights sold.
MOXY will pay the fees charged by the Subscription Agent for effecting such
sale.  Orders to sell Rights must be received by the Subscription Agent prior to
11:00 a.m., New York City time, on the third Nasdaq trading day preceding the
Expiration Date.  If less than all sales orders received by the Subscription
Agent can be filled, sales proceeds will be prorated among the Holders based
upon the number of Rights each Holder has instructed the Subscription Agent to
sell during such period, irrespective of when during such period the
instructions are received by the Subscription Agent.  The Subscription Agent's
obligation to execute orders for the sale of Rights is subject to its ability to
find buyers.  Any Rights that cannot be sold by the Subscription Agent by 5:00
p.m., New York City time the third Nasdaq trading day preceding the Expiration
Date, will be returned promptly by mail to the Holder.

     Holders wishing to transfer all or a portion of their Rights (but not
fractional Rights) should allow a sufficient amount of time prior to the
Expiration Date for (i) the transfer instructions to be received and processed
by the Subscription Agent, (ii) a new Subscription Certificate to be issued and
transmitted to the transferee or transferees with respect to transferred Rights,
and to the transferor with respect to retained Rights, if any, and (iii) the
Rights evidenced by such new Subscription Certificates to be exercised or sold
by the recipients thereof.  Neither MOXY nor the Subscription Agent shall have
any liability to a transferee or transferor of Rights if Subscription
Certificates are not received in time for exercise or sale prior to the
Expiration Date.

     Except for the fees charged by the Subscription Agent (which will be paid
by MOXY as described below), all commissions, fees and other expenses (including
brokerage commissions and transfer taxes) incurred in connection with the
purchase, sale or exercise of Rights will be for the account of the transferor

                                      -21-
<PAGE>
 
of the Rights, and none of such commissions, fees or expenses will be paid by
MOXY or the Subscription Agent.

FOREIGN AND CERTAIN OTHER STOCKHOLDERS

     Subscription Certificates will not be mailed to Holders or to any
subsequent transferees of any Subscription Certificates whose addresses are
outside the United States or who have APO or FPO addresses, but will be held by
the Subscription Agent for such Holders' accounts.  To exercise or sell their
Rights, such Holders must notify the Subscription Agent prior to 11:00 a.m., New
York City time, three Nasdaq trading days prior to the Expiration Date, at which
time (if no contrary instructions have been received) the Rights represented
thereby will be sold, subject to the Subscription Agent's ability to find a
purchaser.  Any such sales will be at prevailing market prices.  See "--Method
of Transferring Rights." If the Rights can be sold, a check for the proceeds
from the sale of any Rights, less any applicable brokerage commissions, taxes
and other expenses, will be remitted to such Holders by mail.  The proceeds, if
any, resulting from sales of Rights of Holders whose addresses are not known by
the Subscription Agent or to whom delivery cannot be made will be held by the
Subscription Agent in a noninterest bearing account.  Any amount remaining
unclaimed on the second anniversary of the Expiration Date will be turned over
by the Subscription Agent to MOXY and, after such date, any person claiming such
proceeds will, as an unsecured general creditor of MOXY, be entitled to look
only to MOXY for payment thereof.

     On July 14, 1997 the last reported sales price of the Common Stock was $3
5/8.  As of July 14, 1997, there were 11,554 record 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.

                                    DILUTION

     The unaudited net tangible book value of the Common Stock as of March 31,
1997, was approximately $5.9 million, or $0.42 per share.  See "Capitalization."
"Net tangible book value per share" represents the amount of total tangible
assets less total liabilities divided by the number of shares of Common Stock
outstanding.  After giving effect to the consummation of the Rights Offering
(assuming full exercise of the Rights) and after deducting the estimated
offering expenses, including the Standby Fee, the unaudited net tangible book
value of the Company as of March 31, 1997, would have been approximately $101.2
million, or $2.37 per share.  This represents an immediate increase in unaudited
net tangible book value of $1.95  per share to persons holding shares of Common
Stock prior to the exercise of the Rights and an immediate dilution of $1.13 per
share to Holders exercising Rights.  The following table illustrates this per
share dilution at March 31, 1997.

     The foregoing assumes no exercise of the options issued to employees of the
Company under MOXY's Stock Option Plan.  At June 30, 1997, options to purchase
approximately 2,304,000 shares of Common Stock were outstanding with a weighted
average exercise price of $3.77 per share.

          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.  However, 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.

       On __________ 1997, MOXY's shareholders approved the Rights Offering and
related transactions allowing for the issuance of approximately 28.6 million
shares of MOXY common stock, estimated to generate gross proceeds of
approximately $100 million.  These proceeds will enable MOXY to acquire the MCN
Producing Properties and to retire all MOXY debt.  Furthermore, the remaining
cash proceeds will provide MOXY with the funding necessary to participate in the
aggregate $200 million multi-year MOXY/FRP Exploration Program (discussed
below).  MOXY will retain a 100% interest in the MCN Producing Properties, and
MOXY and FRP will dedicate all other properties which were subject to the
MOXY/MCN Program to the MOXY/FRP Exploration Program.

       MOXY and FRP will establish 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 will manage the 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 program, with exploration expenses
being shared 40% by MOXY and 60% by FRP.  All revenues and other costs will be
shared equally.

                                      -27-

       MOXY was high bidder on seven tracts at the Central Gulf of Mexico lease
sale held in March 1997 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.

       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, $0.9 million in drilling and leasehold costs charged to
expense and $1.5 million of geological and geophysical costs.  Exploration
expenditures are 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 completion of the Rights Offering, MOXY will purchase the MCN Producing
Properties (Vermilion Block 160 and 410 Fields), and MOXY and FRP will dedicate
all other oil and gas properties subject to the MOXY/MCN Program to the MOXY/FRP
Exploration Program.

     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 unit 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 73 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

                                      -28-
<PAGE>
 
         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 gas 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 completion of the Rights
Offering, MOXY intends to purchase the MCN interest in the Vermilion Block 160
and 410 Fields from FRP. See the unaudited Pro Forma Results of Operations
contained in this Prospectus.

                                      -29-

     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.

                           -------------------------

The results of operations reported and summarized above are not necessarily
indicative of future operating results.

                            BUSINESS AND PROPERTIES

    The Company is an independent oil and gas company engaged in the
exploration, development and production of oil and natural gas.  The Company
currently conducts operations offshore in the Gulf and onshore in the Gulf Coast
area.  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 extensive  technical and operational
expertise.

    The Company's business strategy is to create value for its stockholders
through the discovery of oil and gas reserves by concentrating its efforts in
selected geographic areas where the Company's management team has significant
exploration experience.  The Company evaluates substantially all of its
exploratory prospects with 3-D seismic surveys prior to drilling.  MOXY intends
to continue to generate prospects, evaluate farm-in opportunities and other
opportunities to acquire oil and gas properties and to maximize its geological
and geophysical expertise by using 3-D seismic data and state of the art
technology.

    In order to increase both the size and number of prospects that the Company
has been able to pursue, the Company has followed a strategy of forming
exploration joint ventures in which the venturers participate in the Company's
exploration activities through direct working interests.

MOXY/MCN PROGRAM

    In September 1995, the Company and affiliates of MCN established the
MOXY/MCN Program to explore and develop prospects in the Gulf.  The Company
manages the MOXY/MCN Program and selects all prospects and drilling
opportunities.  The Company and MCN committed $65 million to the MOXY/MCN
Program, with revenues and costs being shared 40% by MOXY and 60% by MCN.  MCN
has funded its 60% share of expenditures and is committed to lend funds to MOXY
for its 40% share.  The Company's 40% share of future revenues from the MOXY/MCN
Program is dedicated to repaying the loan amounts which bear interest at the
annual base rate quoted from time to time by The Chase Manhattan Bank plus 2%.
The Company's obligation to repay loans under the MOXY/MCN Program is non-
recourse, except to the properties contributed to and developed under the
MOXY/MCN Program.

    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 attributable to 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 the date of completion of the Rights Offering.  The amendment also
provides that FRP will reimburse MOXY for approximately $290,000 of overhead 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 for the 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 

                                      -31-
<PAGE>
 
announced by The Chase Manhattan Bank from time to time plus 2%. See "Business
and Properties - Oil and Gas Properties - Proved Properties." At the same time,
MOXY will repay to FRP all amounts that have been advanced to MOXY under the
MOXY/MCN Program. Thereafter, MOXY will retain a 100% interest in the MCN
Producing Properties and will dedicate all other oil and gas properties then
subject to the MOXY/MCN Program to the MOXY/FRP Exploration Program. See "Use of
Proceeds" and "- MOXY/FRP Exploration Program."

MOXY/FRP EXPLORATION PROGRAM

    Concurrently with the closing of the Standby Commitment, MOXY and FRP will
establish the MOXY/FRP Exploration Program to explore and develop exploratory
prospects primarily in the Gulf and onshore in the Gulf Coast area.  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 have committed $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.  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 other costs will be shared 50% by MOXY and
50% by 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 on June 30, 2002, whichever is earlier.

MOXY/PHILLIPS/FRP PROGRAM

    In June 1995, the Company and Phillips entered into a joint venture
agreement to explore a project area in Terrebonne Parish, Louisiana containing
the North Bay Junop and East Fiddler's Lake prospects.  Pursuant to the
agreement, the Company conveyed one-half of its interest in the area, with
Phillips reimbursing the Company $3.8 million for previously incurred costs
related to the project.  In June 1996, the Company sold one-half of its
remaining 50% interest in the area to FRP for $2.1 million.  This amount
represented the reimbursement for certain costs previously incurred by the
Company in connection with this project area.  MOXY sold the interest to FRP on
the same proportionate basis as the sale of the interest to Phillips. The
project area, with the exception of the North Bay Junop and East Fiddler's Lake
prospects, is subject to a possible 25% participation by a mineral rights owner.

OIL AND GAS PROPERTIES

    As of May 31, 1997, the Company owned interests in 39 oil and gas leases in
the Gulf and onshore Louisiana covering approximately 131,300 gross acres
(approximately 41,900 net acres to the Company).

    PROVED PROPERTIES

    After the completion of the Rights Offering and the purchase of the MCN
Producing Properties, MOXY will own all of the interest in the following
properties presently held subject to the MOXY/MCN Program.

                                      -32-
<PAGE>
 
    VERMILION BLOCK 160 FIELD AREA.  Gross production from the field unit
averaged 14.9 Mmcf of natural gas and 687 Bbls of condensate per day during 1996
and currently is averaging 10 Mmcf and 400 Bbls of condensate per day.  The
MOXY/MCN Program has a 40% working interest and an approximate 28% net revenue
interest in the Vermilion Block 160 field unit, which is located offshore
Louisiana in approximately 90 feet of water.  In March 1997, MOXY, as operator,
completed drilling a development well that encountered 262 feet of net gas pay
from eight sands.  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.  Production
from the new development wells is expected to commence during the second half of
1997.  The current working and net revenue interests within the Vermilion Block
160 field unit are subject to re-determination subsequent to final development
drilling.  In Vermilion Block 160, outside the field unit area, the MOXY/MCN
Program has a 53.3% working interest and an approximate 42.5% net revenue
interest.  Also, in Vermilion Block 143, outside the field unit area, the
MOXY/MCN Program has a 26.67% working interest and an approximate 19% net
revenue interest. The MOXY/MCN Program's interest in Vermilion Blocks 143 and
160,  including the portion of its interest in the field unit resulting from
these two blocks, is subject to a 30% net profits interest. The Vermilion Block
160 field unit is comprised of portions of four leases (Vermilion Blocks 143,
144, 159, and 160) totaling 5,625 acres.  In addition, the MOXY/MCN Program owns
interests in, or exploration rights to, an additional 9,375 acres in the four
block area, including the farm-in of 3,125 acres in Vermilion Block 159.  See "-
- - Exploration Properties -- Vermilion Block 159."

    VERMILION BLOCK 410 FIELD AREA.  The MOXY/MCN Program has a 37.5% working
interest and 28% net revenue interest in the Vermilion Block 410 field which is
located in 360 feet of water offshore Louisiana.  Blazer Energy Corp., as
operator, initiated production from four wells at one platform in late December
1996.  Production from four wells at the second platform began in February 1997
and gross daily production from both platforms combined currently is
approximately 73 Mmcf of gas.  The lease blocks cover a total of 11,015 acres.

    EXPLORATION PROPERTIES

    After completion of the Rights Offering, the following properties will be
dedicated to the MOXY/FRP Exploration Program.

    GRAND ISLE BLOCK 65.  The MOXY/MCN Program has a 37.5% working interest and
30.2% net revenue interest in Grand Isle Block 65, where Nippon Oil Exploration,
the operator, has drilled and saved the #1 sidetrack discovery well. The well
encountered two gas bearing zones with a total of 29 feet of net pay.  Nippon
Oil has obtained a suspension of production for the initial well.  The MOXY/MCN
Program acquired the adjacent Grand Isle Blocks 58 and 59 in the Central Gulf of
Mexico lease sale in 1996.  MOXY has received a new 3-D survey over a portion of
the three blocks and exploratory drilling is expected to commence during July
1997.  The prospect is located 23 miles offshore Louisiana in a water depth of
135 feet and the blocks cover a total of 15,000 acres.

    VERMILION BLOCK 159.  In 1996 MOXY completed a farm-in of a portion of
Vermilion Block 159, which is adjacent to its producing property at Vermilion
Block 160.  A well is drilling at a location remote from the existing platform
in Block 160 in July 1997.  The MOXY/MCN Program has a 60% working interest and
a 43% net revenue interest in the Vermilion Block 159 farm-in.

    WEST CAMERON BLOCK 616.  The MOXY/MCN Program has a 50% working interest and
34.4% net revenue interest in West Cameron Block 616, where MOXY, as operator,
drilled the #2 exploration well in June 1996 and discovered 190 feet of net gas
pay in multiple sands.  The well was saved for future development.  A second
exploratory well, the #3 well, is planned for the third quarter of 1997.  The
MOXY/MCN Program also owns an interest in the adjacent West Cameron Block 617
lease where exploratory drilling is contemplated in the fourth quarter of 1997.
The blocks cover a total of 10,000 acres and are located approximately 130 miles
offshore Louisiana in 300 feet of water.

                                      -33-

    WEST CAMERON BLOCK 492.  The MOXY/MCN Program acquired a 100% working
interest and 80% net revenue interest in West Cameron Block 492 in the Central
Gulf of Mexico lease sale in 1996. The block covers 5,000 acres and is located
90 miles offshore in 150 feet of water.  In June 1997, the MOXY/MCN Program
exchanged 50% of its interest in West Cameron Block 492 for a 50% working
interest in Eugene Island Blocks 18 and 19.

    EUGENE ISLAND BLOCKS 18/19.  The MOXY/MCN Program acquired in June 1997 a
50% working interest in Eugene Island Blocks 18 and 19 in exchange for a 50%
working interest in West Cameron Block 492.  Shell Offshore Inc., as operator,
immediately thereafter commenced drilling an exploratory well.  The blocks cover
a total of 2,436 acres and are located 3 miles offshore of Louisiana in
approximately 10 feet of water.

    VERMILION BLOCKS 391/392/408.  The MOXY/MCN Program has a 30% working
interest and 24.1% net revenue interest in Vermilion Blocks 392/408 and a 31.9%
working interest and 25.7% net revenue interest in Vermilion Block 391.  Blazer
Energy Corp., as operator, drilled an unsuccessful exploratory well in the third
quarter of 1996 on Vermilion Block 391. The MOXY/MCN Program acquired the
Vermilion Block 392 lease in the Central Gulf of Mexico lease sale in 1996 and
acquired the shallow rights on Vermilion Block 408 by trading the deep rights at
Vermilion Block 392.  Vermilion Blocks 391/392/408 cover a total of 15,000 acres
and are located four miles from the Vermilion Block 410 field, which  is
approximately 115 miles offshore Louisiana, in approximately 360 feet of water.

    EAST FIDDLER'S LAKE/NORTH BAY JUNOP.  MOXY has a 25% working interest and
18% net revenue interest in approximately 8,925 acres in the East Fiddler's
Lake/North Bay Junop prospects and adjacent areas in Terrebonne Parish,
Louisiana, and owns a proprietary 3-D seismic data survey covering approximately
35,000 acres.  Operations are being undertaken by a joint venture owned 50% by
Phillips (operator), 25% by FRP and 25% by MOXY.  See "- Business and Properties
- -- MOXY/Phillips/FRP Program."  The first exploratory well at East Fiddler's
Lake was drilled in the third quarter of 1996.  Although the well was
unsuccessful in discovering commercial hydrocarbons, the geological data from
this well will assist additional drilling activity in the prospect area. In
April 1997, the North Bay Junop well completed drilling.  The well did not
encounter commercial hydrocarbons in the primary objective zones.  Subsequently,
the well was completed in a shallower zone, which consists of two sands with
approximately 25 feet of net gas pay.  The well was flow-tested at a rate of
approximately 5.3 Mmcf of natural gas and 93 barrels of condensate per day on a
20/64th inch choke with approximately 2,900 pounds per square inch flowing
tubing pressure.  Because of the complexities of salt dome geology, production
performance will be required to determine the reserve volumes associated with
this completion.  Plans to initiate production are currently in progress with
production estimated to commence in the fourth quarter.  Additional leads are
being studied in the project area.

    LEASE SALE.  MOXY was high bidder on seven tracts at the Central Gulf of
Mexico lease sale held in March 1997 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.

OIL AND GAS RESERVES

    The total proved developed and proved undeveloped reserves of oil and gas
owned by the Company and the proved reserves attributable to the MCN Producing
Properties as of May 31, 1997, estimated by Ryder Scott Company, Petroleum
Engineers ("Ryder Scott"), an independent petroleum engineering firm, were as
follows:

    The wells at the Vermilion Block 160 field unit and Vermilion Block 410
field have limited production history.  Estimates of proved undeveloped reserves
that may be developed and produced in the future are based upon volumetric
calculations and upon analogy to similar types of reserves rather than upon
actual production history.  Estimates based on these methods are generally less
reliable than those based on actual production history.  Subsequent evaluation
of the same reserves based upon production history will result in variations,
which may be substantial, in the estimated reserves.  Further, the proved
undeveloped reserves will require additional capital to develop and produce.
See "Management's Discussion and Analysis of Financial Condition and Results of
Operations."

    The following table sets forth as of May 31, 1997, the estimated future net
cash flows before income taxes and the present value thereof, discounted at 10%
per annum, from the production and sale of the proved reserves attributable to
the gas and oil properties owned by the Company as of such date and the proved
reserves attributable to the MCN Producing Properties, as determined by Ryder
Scott.

- --------------
(1)    In preparing such estimates, Ryder Scott used prices of $20.15 per barrel
       of oil and $2.21 per Mcf of gas as of May 31, 1997, the weighted average
       prices that the Company estimates it would have been received, assuming
       production from all of the properties with proved reserves.

                                 _____________

    In accordance with applicable requirements of the Commission, the estimated
discounted future net revenues from estimated proved reserves are based on
prices and costs at the time of the reserve calculation.  Actual future prices
and costs may be materially higher or lower.  See "Risk Factors - Reserves and
Future Net Cash Flow."

                                      -35-
<PAGE>
 
    In accordance with methodology approved by the Commission, specific
assumptions were applied in the computation of the reserve estimates.  Under
this methodology, future net cash flows are determined by reducing estimated
future gross cash flows from oil and gas sales by the estimated costs to develop
and produce the underlying reserves, including future capital expenditures,
operating costs, transportation costs, net profits interests, and royalty and
overriding royalty burdens.  Future net cash flows were discounted at 10% per
annum to arrive at discounted future net cash flows.  The present value of
future net cash flows shown above should not be construed as the current market
value as of May 31, 1997, or any other date, of the estimated oil and gas
reserves attributable to these properties.  See "Risk Factors - Reserves and
Future Net Cash Flow."

    The Company is periodically required to file estimates of its oil and gas
reserves with various governmental regulatory authorities and agencies.  In some
cases the basis for reporting estimates of reserves to these agencies is not
comparable to that furnished above because of the nature of the reports
required.  The major variations include differences in when such estimates are
made, in the definition of reserves, in the requirements to report in some
instances on a gross, net or total operator basis and in the requirements to
report in terms of smaller geographical units.

PRODUCTION, UNIT PRICES AND COSTS

    The following table sets forth information regarding production volumes,
average sales, prices received and average production costs applicable to the
Company's oil and gas sales for the year ended December 31, 1996 and the three

       barrel of oil being equivalent to six Mcf of natural gas.  Production
       costs exclude all depreciation and amortization associated with property
       and equipment.  The components of production costs may vary substantially
       among wells depending on the production characteristics of the particular
       producing formation, the method of recovery employed and other factors,
       but include in all cases transportation charges and lease operating
       expenses.

    The relationship between the Company's sales prices and its production

OPERATING HAZARDS AND INSURANCE

    The Company's operations are subject to the usual hazards incident to
drilling for and producing natural gas and crude oil, such as blowouts,
cratering, explosions, uncontrollable flows of oil, gas or well fluids, fires,
pollution, releases of toxic gas and other environmental hazards and risks.
Offshore oil and gas operations are subject to the additional hazards of marine
operations, such as capsizing, collision and adverse weather and sea conditions.
These hazards can cause personal injury and loss of life, severe damage to and
destruction of property and equipment, environmental damages and suspension of
operations.

    Drilling activities are subject to numerous risks, including the risk that
no commercially productive hydrocarbon reserves will be encountered.  The cost
of drilling, completing and operating wells and installing production facilities
and pipelines is often uncertain.  The Company's drilling operations may be
curtailed, delayed or canceled as a result of numerous factors, including,
weather 

                                      -37-
<PAGE>
 
conditions, compliance with governmental requirements and shortages or delays in
the delivery of equipment.

    The Company maintains insurance of various types that it considers to be
reasonably adequate to cover its operations, although certain risks faced by the
Company are either uninsurable or not fully insured.  Such insurance is subject
to deductibles that the Company considers reasonable.  Consistent with insurance
coverage generally available to the industry, the Company's insurance policies
do not provide coverage for losses or liabilities relating to pollution, except
for sudden and accidental occurrences.

COMPETITION

    Competition in the oil and gas industry is intense.  In seeking to obtain
new leases and exploration prospects, the Company faces competition from both
major and independent oil and gas companies.  Because many of these competitors
have financial and other resources substantially in excess of those available to
the Company, they may be better positioned to acquire and exploit prospects,
hire personnel and market production.  In addition, many of the Company's larger
competitors may be better able to withstand the effect of changes in such
factors as worldwide oil and natural gas prices and levels of production, the
cost and availability of alternative fuels and the application of government
regulations.

MARKETING

    The Company's gas sales are currently made in the "spot market" at
prevailing prices. Crude oil and condensate production is generally sold one
month at a time at prevailing prices.

REGULATION

    GENERAL

    The oil and gas industry is extensively regulated by federal and state
authorities in the United States.  Legislation affecting the oil and gas
industry is under constant review, and relevant statutes are constantly being
adopted, expanded or amended.  Further, numerous departments and agencies, both
federal and state, have issued rules and regulations binding on the oil and gas
industry and its individual members, some of which carry substantial penalties
for the failure to comply.  The regulatory burden on the oil and gas industry
increases its cost of doing business and, consequently, affects its
profitability.

    EXPLORATION, PRODUCTION AND DEVELOPMENT

    The exploration, production and development operations of the Company are
subject to regulation at both the federal and state levels.  Such regulations
require operators to obtain permits to drill wells and to meet certain bonding
and insurance requirements in order to drill or operate wells.  Such regulation
also controls the location of wells, the method of drilling and casing wells,
the surface use and restoration of properties upon which wells are drilled and
the plugging and abandoning of wells.  The Company's exploration, production and
development operations are also subject to various conservation laws and
regulations.  These include the regulation of the size of drilling and spacing
units or proration units, the density of wells that may be drilled, the levels
of production and the unitization or pooling of oil and gas properties.

    The Company presently has interests in or rights to 30 offshore leases
located in federal waters on the outer continental shelf ("OCS"). Federal leases
are administered by the Minerals Management Service  ("MMS").  Individuals and
entities must qualify with the MMS prior to owning and operating any leasehold
or right-of-way interest in federal waters.  Such qualification generally
involves filing certain documents with the MMS and obtaining performance bonds.
For offshore 

                                      -38-
<PAGE>
 
operations, lessees must obtain MMS approval for exploration plans and
development and production plans prior to the commencement of such operations.
In addition to permits required from other agencies (such as the Coast Guard,
the Army Corp of Engineers and the Environmental Protection Agency), lessees
must obtain a permit from the MMS prior to the commencement of drilling. The MMS
has promulgated regulations requiring offshore production facilities located on
the OCS to meet stringent engineering and construction specifications, and has
recently proposed and promulgated additional safety-related regulations
concerning the design and operating procedures of OCS production platforms and
pipelines. The MMS also has regulations restricting the flaring or venting of
natural gas, and has proposed amendments to such regulations that would prohibit
the flaring of liquid hydrocarbons and oil without prior authorization. The MMS
has also promulgated regulations governing the plugging and abandonment of
offshore wells and the removal of production facilities. To cover the various
obligations of an OCS lease, the MMS generally requires that lessees post
substantial bonds or other acceptable assurances that such obligations will be
met. The cost of such bonds or other security can be substantial and there is no
assurance that bonds or other surety can be obtained in all cases. Under certain
circumstances, the MMS may require all Company operations on federal leases to
be suspended or terminated. Any such suspension or termination would materially
and adversely affect the Company's financial condition and operations.

    Certain producing states, including Louisiana, have recently adopted or
considered adopting measures that alter the methods used to prorate gas
production from wells located in these states, including those located in their
territorial waters.  These measures may limit the rate at which gas may be
produced from the wells in which the Company might acquire an interest.
Congress considered, but rejected, legislation that would  have limited the
rights of states to prorate production.  The Company cannot predict whether such
legislation will be reintroduced or what effect the new state rules may have on
gas production in such states.  At the present time there are no regulatory
measures that would limit the production of oil or gas leases in which the
Company owns an interest.

    ENVIRONMENTAL

    GENERAL.  The Company's operations are subject to extensive federal, state
and local regulatory requirements relating to environmental affairs, health,
safety, waste management and chemical products.  These laws and regulations
require the acquisition of permits before construction or drilling commences,
limit or prohibit construction and drilling activities on certain lands lying
within wilderness, wetland and other protected areas and impose substantial
liabilities for pollution resulting from the Company's operations.

    Moreover, the recent trend toward stricter standards in environmental
legislation and regulations is likely to continue.  For instance, legislation
has been proposed in Congress from time to time to reclassify oil and gas
production wastes as "hazardous waste."  If such legislation were enacted, it
could have a significant impact on the operating costs of the Company, as well
as the oil and gas industry in general.  State initiatives to further regulate
the disposal of oil and gas wastes are also pending in certain states and could
have a similar impact on the Company. Management believes that compliance with
current applicable environmental laws and regulations will not have a material
adverse effect on the Company.  The Company believes that its operations are and
will continue to be in substantial compliance with applicable environmental
laws, regulations and ordinances.

    It is possible, however, that future developments, such as stricter
environmental laws or regulations could adversely affect the Company's
operations.  Moreover, some risk of environmental costs and liabilities is
inherent in the Company's operations as it is with other companies engaged in
similar or related businesses, and there can be no assurance that material costs
and liabilities, including substantial fines or criminal sanctions for violation
of environmental laws and regulations, will not be incurred by the Company.

    SOLID WASTE.  The Company's operations may generate or involve the transport
of both hazardous and nonhazardous solid wastes that are subject to the
requirements of the Federal Resource Conservation and Recovery Act and
comparable state statutes.  In addition, the Environmental Protection  Agency
("EPA") is presently in the process of developing stricter disposal standards
for nonhazardous waste.  Changes in these regulations may require additional
capital expenditures or operating expenses by the Company.

    HAZARDOUS SUBSTANCES.  The Comprehensive Environmental Response,
Compensation and Liability Act ("CERCLA") and comparable state statutes, also
known as "Superfund" laws, impose liability on certain classes of persons that
contribute to the release of a "hazardous substance" into the environment.
These persons include the owner or operator of a site, and companies that
transport, dispose of or arrange for the disposal of, the hazardous substances
found at the site.  CERCLA also authorizes the EPA, and in some cases third
parties, to take actions in response to threats to the public health or the
environment and to recover their costs from the responsible classes of persons.
Despite the "petroleum exclusion" of Section 101(14) of CERCLA that encompasses
wastes directly associated with oil and gas production, the Company may generate
or transport "hazardous substances" within the meaning of CERCLA or comparable
state statutes in the course of its ordinary operations. Thus, the Company may
be responsible under CERCLA or the state equivalents for all or part of the
costs required to clean up sites where a release has occurred.

    AIR.  The Company's operations may also be subject to the Clean Air Act
("CAA") and comparable state statutes.  Amendments to the CAA were adopted in
1990 and contain provisions that may result in the gradual imposition of certain
pollution control requirements with respect to air emissions from operations.
The EPA has been developing regulations to implement these requirements.  The
Company may be required to incur certain capital expenditures in the next
several years for air pollution control equipment in connection with obtaining
or maintaining operating permits and approvals addressing other air emission-
related issues.

    WATER.  The Federal Water Pollution Control Act ("FWPCA") strictly regulates
the unauthorized discharge of produced waters and other oil and gas wastes into
navigable waters.  The FWPCA provides for civil and criminal penalties for any
unauthorized discharges of oil and other hazardous substances in reportable
quantities and imposes substantial potential liability for the costs of removal,
remediation and damages.  Similarly, the Oil Pollution Act of 1990 (the "OPA")
imposes liability for the discharge of oil into or upon navigable waters or
adjoining shorelines. Among other things, the OPA raises liability limits,
narrows defenses to liability and provides more instances in which a responsible
party is subject to unlimited liability.  State laws for the control of water
pollution also provide varying civil and criminal penalties and liabilities in
the case of an unauthorized discharge of petroleum or its derivatives into state
waters.  Further, the Coastal Zone Management Act authorizes state
implementation and development of programs or management measures for nonpoint
source pollution to restore and protect coastal waters.

    ENDANGERED SPECIES.  Several federal laws impose regulations designed to
ensure that endangered or threatened plant and animal species are not
jeopardized and their critical habitats are neither destroyed nor modified.
These laws may restrict the Company's exploration, development and production
operations and impose civil or criminal penalties for non-compliance.

    SAFETY AND HEALTH REGULATIONS

    The Company is also subject to laws and regulations concerning occupational
safety and health.  It is not anticipated that the Company will be required in
the near future to expend amounts that are material in the aggregate to the
Company's overall operations by reason of occupational safety and health laws
and regulations, but inasmuch as such laws and regulations are frequently
changed, the Company is unable to predict the ultimate cost of compliance.

EMPLOYEES

    At June 30, 1997, the Company had 15 employees.  All of the Company's
employees are devoted primarily to managerial, land, geological and
administrative functions.  The Company intends to continue its policy of
limiting its number of permanent employees and, to that end, generally utilizes
the services of independent consultants and contractors to perform various
professional services, particularly in the areas of construction, design, well
site surveillance and environmental assessment.  Field and on-site production
operation services such as pumping, maintenance, dispatching, inspection and
testing  are also generally provided by independent contractors.  Currently, a
major portion of the Company's geological and geophysical services are performed
by CLK Company, L.L.C. ("CLK").  Under the Company's agreement with CLK,  the
Company pays CLK an annual fee of $2.4 million, with $0.5 million of this fee
paid in Company common stock, and reimburses CLK's direct expenses incidental to
its work for the Company and for its office space.  In addition, CLK receives a
3% overriding royalty interest on all new domestic prospects accepted by the
Company.  For the year ended December 31, 1996, the Company incurred $3.1
million of expenses under its agreement with CLK.

     The directors of the Company who also serve as directors of FTX and FCX

     The Company's Amended and Restated Certificate of Incorporation
("Certificate" or "Certificate of Incorporation") provides that the directors
shall be classified, with respect to the time for which they severally hold
office, into three classes, as nearly equal in number as possible, and that one
class shall be elected each year and serve a three-year term.  Mr. Harrison and
Dr. Wharton were elected in April 1997 to serve a term that expires at the 2000
annual meeting of stockholders.  Messrs. Moffett, Putnam and Rankin and Ms.
McDonald serve a term expiring at the 1998 annual meeting of stockholders, and
Messrs. Adkerson, Bruce, Day and Lackey serve a term that expires at the 1999
annual meeting of stockholders.  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.

     On or before January 14, 1998, the Company's Board of Directors will take
such actions 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 its Certificate of Incorporation and By-Laws, (ii) director resignations or
(iii) a combination thereof.  MOXY will also 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 (each as defined under the Securities Act)
of FRP, other than solely as a result of being a director of MOXY 

                                      -43-
<PAGE>
 
(each an "Independent Director"). MOXY will maintain at all times a committee of
the Board of Directors comprised of all such Independent Directors then on the
Board (the "Independent Committee"). See "Description of Capital Stock -
Stockholder Agreement and Registration Rights."

     Pursuant to the Stockholder Agreement, as long as FRP owns more than 10%
and less than a majority of the outstanding Common Stock, 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 after giving
effect to the FRP designees.  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 Bylaws,
(ii) director resignations or (iii) a combination thereof.  If FRP acquires more
than a majority of the outstanding shares of Common Stock, it will be able to
elect all of the directors of MOXY.  See "Risk Factors - Potential Change of
Control of the Company" and "Description of Capital Stock - Stockholder
Agreement and Registration Rights."

     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 the Stockholder Agreement, if such director declines or is unable to
serve for any reason, at termination of such directors term, or upon such
directors resignation or removal.

     At the present time, all of the MOXY directors are also directors of FTX.
Accordingly, FRP does not intend to use this provision to make any changes to
the current composition of the Board, subject to the appointment of the
Independent Directors.

                 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 substantially all 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 FCX, 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 

                                      -44-
<PAGE>
 
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.

     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
Prospectus, 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 

                                      -47-
<PAGE>
 
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 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 

                                      -48-
<PAGE>
 
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 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.

                                      -49-

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.

     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.

                                      -50-
<PAGE>
 
     "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 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

                                      -51-
<PAGE>
 
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 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.

                   CERTAIN FEDERAL INCOME TAX CONSIDERATIONS

     The following is a general summary of certain United States federal income
tax considerations applicable to holders of Common Stock upon the issuance,
exercise, disposition and lapse of the Rights.  In the opinion of Jones, Walker,
Waechter, Poitevent, Carrere & Denegre, L.L.P., special counsel to the Company,
the following summarizes the federal income tax consequences of the Rights
Offering that are likely to be material to the Holders (other than the Holders
described below) upon the issuance, exercise, disposition and lapse of the
Rights.  This summary is based upon the Internal Revenue Code of 1986, as
amended (the "Code"), Treasury Regulations (including Proposed Regulations and
Temporary Regulations) promulgated thereunder, Internal Revenue Service ("IRS")
rulings, official pronouncements and judicial decisions, all as in effect on the
date hereof and all of which are subject to change, possibly with retroactive
effect, or different interpretations.  This summary is applicable only to
Holders who are United States persons for federal income tax purposes and who
hold Common Stock as capital assets and who will hold any Common Stock received
on exercise of the Rights as capital assets.  This summary does not discuss all
aspects of federal income taxation that may be relevant to a particular investor
or to certain types of investors subject to special treatment under the Code
(for example, banks, dealers in securities, life insurance companies, tax exempt
organizations and foreign taxpayers), nor does it discuss any aspect of state,
local or foreign tax laws.

     HOLDERS OF RIGHTS AND COMMON STOCK ARE ADVISED TO CONSULT THEIR OWN TAX
ADVISORS REGARDING THE FEDERAL, STATE, AND LOCAL TAX CONSEQUENCES OF THE
ISSUANCE, EXERCISE, DISPOSITION AND LAPSE OF THE RIGHTS IN LIGHT OF THEIR OWN
PARTICULAR CIRCUMSTANCES.

ISSUANCE OF THE RIGHTS

     The holders of Common Stock will not recognize taxable income for federal
income tax purposes in connection with the receipt of the Rights.

                                      -52-
<PAGE>
 
BASIS AND HOLDING PERIOD OF THE RIGHTS

     If, either (i) the fair market value of the Rights on the date of issuance
is equal to 15% or more of the fair market value (on the date of issuance) of
the Common Stock with respect to which they are received or (ii) the stockholder
elects, in his or her federal income tax return of the taxable year in which the
Rights are received, to allocate part of the basis of such Common Stock to the
Rights, then upon exercise or transfer of the Rights, the stockholder's basis in
such Common Stock will be allocated between the Common Stock and the Rights in
proportion to the fair market values of each on the date of the issuance.
Except as provided in the preceding sentence, the basis of the Rights received
by a stockholder as a distribution with respect to such stockholder's Common
Stock will be zero.

     The holding period of a stockholder with respect to the Rights received as
a distribution on such stockholder's Common Stock will include the stockholder's
holding period for the Common Stock with respect to which the Rights were
issued.

     In the case of a purchaser of Rights, the tax basis of such Rights will be
the purchase price of the Rights and the holding period of such Rights will
commence on the day following the date of the purchase.

TRANSFER OF RIGHTS

     A stockholder who sells the Rights received in the issuance prior to
exercise will recognize gain or loss equal to the difference between the sale
proceeds and such stockholder's basis (if any) in the Rights sold.  Such gain or
loss will be capital gain or loss if gain or loss from a sale of Common Stock
held by such stockholder would be characterized as capital gain or loss at the
time of such sale.  Any gain or loss recognized on a sale of Rights acquired by
purchase will be capital gain or loss if the Underlying Shares would be a
capital asset in the hands of the seller (if acquired by him).

LAPSE OF THE RIGHTS

     Stockholders who allow the Rights received by them to lapse will not
recognize any gain or loss, and no adjustment will be made to the basis of the
Common Stock, if any, owned by such holders of the Rights.

     Purchasers of the Rights will be entitled to a loss equal to their tax
basis in the Rights, if such Rights expire unexercised.  Any loss recognized on
the expiration of the Rights acquired by purchase will be a capital loss if the
underlying shares would be a capital asset in the hands of the seller (if
acquired by him).

EXERCISE OF THE RIGHTS; BASIS AND HOLDING PERIOD OF COMMON STOCK

     Holders of Rights will not recognize any gain or loss upon the exercise of
such Rights.  The basis of the Common Stock (including any fractional share
interests) acquired through exercise of the Rights will be equal to the sum of
the Exercise Price therefor and the Holder's basis in such Rights (if any).  The
holding period for the Common Stock acquired through exercise of the Rights will
begin on the date the Rights are considered exercised.

                                 LEGAL MATTERS

     The validity of the issuance of the shares of Common Stock offered hereby
will be passed upon for the Company by Jones, Walker, Waechter, Poitevent,
Carrere & Denegre, L.L.P.

                    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
principles.

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.

stockholders, MOXY's purchase of MCN's interest in the MOXY/MCN Program's
producing properties and the formation of an aggregate $200 million multi-year
exploration program with FRP.

               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.

ITEM 15.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.

  Indemnification.  The Company is incorporated under the laws of the State of
Delaware.  Section 145 of the General Corporation Law of Delaware empowers the
Company to indemnify, subject to the standards therein prescribed, any person in
connection with any action, suit or proceeding brought or threatened by reason
of the fact that such person is or was a director, officer, employee or agent of
the Company.  Article Eighth of the Company's Amended and Restated Certificate
of Incorporation (the "Certificate of Incorporation") and Article XXIV of the
Company's By-Laws (the "By-Laws") provide that each person who was or is made a
party to (or is threatened to be made a party to) or is otherwise involved in
any action, suit or proceeding by reason of the fact that such person is or was
a director, officer, employee or agent of the Company shall be indemnified and
held harmless by the Company to the fullest extent authorized by the General
Corporation Law of Delaware against all expenses, liability and loss (including,
without limitation, attorneys' fees, judgments, fines and amounts paid in
settlement) reasonably incurred by such person in connection therewith.  The
rights conferred by Article Eighth of the Certificate of Incorporation and
Article XXIV of the By-Laws, as the case may be, are contractual rights and
include the right to be paid by the Company the expenses incurred in defending
such action, suit or proceeding in advance of the final disposition thereof.

  Director Liability.  Article Eighth of the Certificate of Incorporation
provides that the Company's directors will not be personally liable to the
Company or its stockholders for monetary damages resulting from breaches of
their fiduciary duty as directors except (a) for any breach of the duty of
loyalty to the Company or its stockholders, (b) for acts or omissions not in
good faith or which involve intentional misconduct or a knowing violation of
law, (c) under Section 174 of the General Corporation Law of Delaware, which
makes directors liable for unlawful dividend or unlawful stock repurchases or
redemptions or (d) transactions from which directors derive improper personal
benefit.

  Insurance.  The Company may purchase and maintain insurance to protect itself
and any person eligible to be indemnified hereunder against any liability or
expense asserted or incurred by such person in connection with any action,
whether or not the Company would have the power to indemnify such person against
such liability or expense by law or under the provisions of the Certificate of
Incorporation. [The Company has an insurance policy insuring the Company's
directors and officers against certain liabilities, including liabilities under
the Securities Act of 1933.

ITEM 17.  UNDERTAKINGS

  The undersigned Registrant hereby undertakes:

  (1) That, for purposes of determining any liability under the Securities Act,
each filing of the Registrant's annual report pursuant to Section 13(a) or
Section 15(d) of the Exchange Act that is incorporated by reference in the
registration statement shall be deemed to be a new registration statement
relating to the securities offered therein, and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.

  (2) Insofar as indemnification for liabilities arising under the Securities
Act may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the foregoing provisions or otherwise, the Registrant has
been advised that in the opinion of the Securities and Exchange Commission such
indemnification is against public policy as expressed in the Securities Act and
is, therefore, unenforceable.  In the event that a claim for indemnification
against such liabilities (other than the payment by the Registrant of expenses
incurred or paid by a director, officer or controlling person of the Registrant
in the successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the Registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Securities Act and will be governed by the final
adjudication of such issue.

Dear Sirs:

     We have acted as your counsel in connection with the preparation of the
registration statement on Form S-3 (the "Registration Statement") filed by you
with the Securities and Exchange Commission on the date hereof, with respect to
the registration of up to 28,611,429 shares of Common Stock, par value $.01 per
share (the "Shares"), and up to 28,611,429 transferable subscription rights to
purchase shares of Common Stock (the "Rights").  The Registration Statement
relates to a proposed rights offering (the "Rights Offering"), pursuant to which
McMoRan Oil & Gas Co. (the "Company") will distribute to holders of record of
Common Stock approximately 2.0 transferable subscription rights for each share
of Common Stock held of record at the close of business on the record date for
the Rights Offering (plus such additional Rights as are necessary to round up to
whole Rights any fractional Rights to which beneficial owners of Common Stock
may be entitled) and the shares of Common Stock to be issued or delivered upon
exercise of the Rights. In so acting, we have examined originals, or photostatic
or certified copies, of such records of the Company, certificates of officers of
the Company and of public officials, and such other documents as we have deemed
relevant.  In such examination, we have assumed the genuineness of all
signatures, the authenticity of all documents submitted to us as originals, the
conformity to original documents of all documents submitted to us as certified
or photostatic copies and the authenticity of the originals of such documents.

     Based upon the foregoing, we are of the opinion that (i) the Rights have
been duly authorized and when issued in accordance with such authorization, will
constitute valid and binding obligations of the Company enforceable against the
Company in accordance with their terms, subject to applicable bankruptcy,
insolvency, reorganization, moratorium and other similar laws affecting
creditors' rights generally and equitable principles of general applicability,
and (ii) the Shares issuable or deliverable upon the exercise of the Rights,
when issued and sold upon the terms described in the Registration Statement,
will be duly authorized, validly issued, fully paid and non-assessable.

Statement and the reference to us under the caption "Legal Matters" as counsel

     Re:  Subscription Rights to Subscribe for and
          Purchase Additional Shares of Common Stock of
          McMoRan Oil & Gas Co.

Gentlemen:

     You have requested our opinion regarding certain federal income tax
consequences applicable to the issuance, exercise, disposition and lapse of the
transferable subscription rights (the "Rights") to subscribe for and purchase
additional shares of common stock, $0.01 par value per share (the "Common
Stock"), of McMoRan Oil & Gas Co. (the "Company").

     In formulating our opinion, we have examined such documents as we have
deemed appropriate, including the Registration Statement of the Company on Form
S-3 filed with the Securities and Exchange Commission pursuant to the Securities
Act of 1933, as amended (the "Securities Act"), to which this opinion is filed
as an exhibit.  In addition, we have obtained such additional information as we
have deemed relevant and necessary through consultation with various officers
and representatives of the Company.

     Based upon the terms of the Rights as set forth in the Registration
Statement, it is our opinion that the discussion set forth under the caption
"Certain Federal Income Tax Considerations" in the Registration Statement
accurately summarizes the material federal income tax consequences generally
applicable to recipients of the Rights.

     The foregoing opinion is based on the Internal Revenue Code of 1986, as
amended, Treasury Regulations promulgated thereunder, Internal Revenue Service
rulings and pronouncements and judicial decisions now in effect, any of which
may be changed at any time with retroactive effect.  No opinion is expressed on
any matters other than those specifically referred to herein.

     We hereby consent to the filing of this opinion as Exhibit 8 to the
Registration Statement and all references to our firm included in or made a part
of the Registration Statement.  In giving such consent, we do not thereby admit
that we come within the category of persons whose consent
