                                     GENERAL

                                    THE TRUST

         Organization. Marine Petroleum Trust ("Marine") is a royalty trust
created in 1956 under the laws of the State of Texas. Marine is not permitted to
engage in any business activity inasmuch as it was organized for the sole
purpose of providing an efficient, orderly, and practical means for the
administration and liquidation of rights to payments from certain oil and
natural gas leases in the Gulf of Mexico, pursuant to license agreements and
amendments thereto between Marine's predecessors and Gulf Oil Corporation
("Gulf"). As a result of various transactions that have occurred since 1956, the
Gulf interests now are held by Chevron Corporation ("Chevron"), Elf Exploration,
Inc. ("Elf"), and their assignees.

         The indenture pursuant to which Marine was created (the "Indenture"),
provides that the corporate trustee is to distribute all cash in Marine, less an
amount reserved for the payment of accrued liabilities and estimated future
expenses, to unitholders of record on the 28th day of September, December, March
and June of each fiscal year. If the 28th falls on a Saturday, Sunday or legal
holiday, the distribution is payable on the immediately preceding business day.

         The Indenture, as amended, also provides that the term of the royalty
trust created thereby will expire on June 1, 2021 unless extended by the vote of
the holders of a majority of the outstanding units of beneficial interest.

         Marine's wholly-owned subsidiary, Marine Petroleum Corporation ("MPC"),
holds title to interests in properties subject to Marine's interests that are
situated offshore of Louisiana. Ninety-eight percent of all oil, natural gas,
and other mineral royalties collected by this subsidiary are paid to Marine.
MPC, like Marine, is prohibited from engaging in a trade or business and does
only those things necessary for the administration and liquidation of its
properties.

         Marine's only industry segment or purpose is the administration and
collection of royalties.

         Royalties. Marine's rights are generally referred to as overriding
royalty interests in the oil and natural gas industry, and are sometimes
referred to herein as such. All production and marketing functions are conducted
by the working interest owners of the leases. Revenues from the overriding
royalties are paid to Marine either (i) on the basis of the selling price of
oil, natural gas and other minerals produced, saved and sold, or (ii) at the
value at the wellhead as determined by industry standards, when the selling
price does not reflect the value at the wellhead.

         Marine holds an overriding royalty interest equal to three-fourths of
1% of the value at the well of any oil, natural gas, or other minerals produced
and sold from the leases described in the "Properties" section below. Marine's
overriding royalty interest applies only to existing leases and does not apply
to new leases. Marine also owns a 32.6% equity interest in Tidelands Royalty
Trust "B" ("Tidelands"), a separate Texas trust, which owns interests in the
oil, natural gas, or other mineral lease acquired by Gulf and/or its transferees
and assignees in a 1,370,000-acre area of the Gulf of Mexico (the "Royalty
Area") during a 50-year period ended April 30, 2001. Prior to the expiration of
the 50-year lease acquisition period on April 30, 2001 (the "Acquisition
Expiration Date"), if Chevron, Elf or their assigns had acquired a lease or
leases on one of the 60 tracts, and if oil or natural gas were produced and sold
from any such tract, then Chevron, Elf or their assigns had to make production
payments to Tidelands, in an amount equal to approximately 12.5% of the value at
the well-head of the oil and natural gas subject to such lease until the sum of
$1,500,000 has been paid under the lease. Thereafter, Tidelands' interest in
such tract was converted to an overriding royalty and Tidelands received
payments equal to approximately 4.17% of the value of the oil and natural gas
sold as long as the lease on such tract exists. At June 30, 2001, six of
Tidelands' assigned leases had paid out their $1,500,000 production payment and,
therefore, Tidelands' royalty interest on six leases was 4.17%. The overriding
royalty on a recently acquired lease on West Cameron Block 251 will initially be
12.5% if any production occurs.

         Presently, the leases subject to Marine's interests cover 275,413 gross
acres (including Tidelands' interest in 29,812 leased acres). These leases will
remain in force until the expiration of their respective terms. Leases may be
voluntarily released by the working interest owner after all oil and natural gas
reserves are produced. They may also be abandoned by the working interest owner
due to failure to discover sufficient reserves to make development




                                       3

economically worthwhile. In addition, the federal government may force
termination if the working interest owner fails to fully develop a lease once it
is acquired.

         For the year ended June 30, 2001, approximately 40% of Marine's royalty
revenues were attributable to the sale of oil and approximately 60% were
attributable to the sale of natural gas. The royalty revenues received by Marine
are affected by seasonal fluctuations in demand and by changes in the market
price for oil and natural gas. Royalty revenue received by Marine from Chevron
and from Devon Energy Production Company, formerly known as Pennzenergy
Exploration and Production Company, ("Devon") accounted in the aggregate for
approximately 82%, 81% and 76% of Marine's royalty revenue for the years ended
June 30, 2001, 2000 and 1999, respectively. Chevron accounted for 75%, 71% and
55% of Marine's royalty revenue for the fiscal years ended June 30, 2001, 2000
and 1999, respectively. Devon accounted for 7%, 10% and 21% of Marine's royalty
revenue for the fiscal years ended June 30, 2001, 2000 and 1999, respectively.
In addition, Marine's revenue from its equity interest in Tidelands accounted
for approximately 7%, 6% and 10% of Marine's revenue for the years ended June
30, 2001, 2000 and 1999, respectively. Tidelands has reported that royalty
revenues from American Explorer Company, Burlington Resources, Chevron, USA,
Pennzenergy Exploration and Production Company and Devon accounted for a
substantial portion of Tidelands' royalty revenue for the years ended December
31, 2000, 1999 and 1998.

         Marine derives no revenues from foreign sources and has no export
sales.

         Trust Functions. Marine is administered by officers and employees of
its Trustee, Bank of America, N.A. MPC employs one individual (its president,
treasurer and director) to perform certain management, financial and
administrative services for Marine. Except for this individual, all officers and
directors of MPC serve without compensation. See "Management and Principal
Unitholders."

         Important aspects of Marine's operations are conducted by third
parties. These include the production and sale of oil and natural gas and the
calculation of royalty payments to Marine, which are conducted by oil and
natural gas companies that lease tracts subject to Marine's interests.
Similarly, Marine's distributions are processed and paid by The Bank of New York
as the agent for the trustee of Marine.

         MPC leases office space in Dallas, Texas to provide work space and
record storage for Marine, MPC, Tidelands and Tidelands' wholly-owned subsidiary
corporation, Tidelands Royalty "B" Corporation. The cost of this office facility
is shared by all four of these entities in proportion to each entity's gross
income to the total of such income of all entities.

         The ability of Marine to receive revenues is entirely dependent upon
its entitlement to its rights with respect to the leases held by Chevron and its
assignees in the Gulf of Mexico (as more fully described in "Properties" below).
Moreover, no revenues are payable to Marine until sales of production commence
from any such lease.

         The royalty interests held by Marine are depleting with each barrel of
oil and mcf of natural gas produced. No funds are reinvested by Marine; thus,
these depleting assets are not being replaced.

                                   PROPERTIES

         General. Marine is not engaged in oil and natural gas operations,
although its income is based upon the oil and natural gas operations of others.
Marine's income is derived from contracts that provide for payments in the
nature of overriding royalties made to Marine based on oil and natural gas sales
from certain leases in the Gulf of Mexico.

         Reserves. Marine is not engaged in the production of oil or natural
gas. Marine's income is derived from overriding royalty payments which are
carved out of working interests in oil and natural gas leases in the Gulf of
Mexico. Marine does not have the engineering data necessary to make an estimate
of the proved oil and natural gas reserves attributable thereto (nor the present
value of future net cash flows from such reserves), and is not entitled to
receive such data from the owners of the working interests from which Marine's
interests are derived. See also "Difficulty in Obtaining Certain Data" below.



                                       4
   5

         Since Marine does not have access to this reserve information, Marine
is unable to compute the standardized measure of discounted future net cash
flows therefrom.

         Marine did not file any reports during the fiscal year ended June 30,
2001 with any federal authority or agency with respect to oil and natural gas
reserves.

         Production. Information regarding the net quantities of oil and natural
gas produced with respect to Marine's overriding royalty interests (excluding
its equity in Tidelands and excluding the income realized from the reduction of
the amounts reserved for royalty over-payments) for each of the last three
fiscal years, as well as the average sales price per unit of oil and natural gas
produced upon which payments to Marine are based, is set forth in the following
table:

         Information about average production cost (lifting cost) per unit of
production has been omitted due to its unavailability and inapplicability to
Marine. For more recent information regarding prices, see "Management's
Discussion and Analysis of Financial Condition and Results of Operations" below.

         Productive Wells. Based on the latest public records available to
Marine, and including its equity interest in Tidelands, there were approximately
375 active wells subject to Marine's interests, some of which contained multiple
completions. Approximately 153 wells were classified as oil wells and
approximately 222 wells were classified as natural gas wells. Most of the oil
wells also produced associated natural gas and most of the natural gas wells
produced condensate, which is economically the equivalent of oil. See
"Difficulty in Obtaining Certain Data" below.

         Drilling Activity. Information concerning the results of operations on
leases in which Marine had an interest (including its equity interest in
Tidelands) for each of its last three fiscal years is set forth below:

         Lease Acreage. Marine has an overriding royalty interest (including its
equity interest in Tidelands) in 73 different oil and natural gas leases
covering 275,413 gross acres. These leases are located in the Central and
Western areas of the Gulf of Mexico off the coasts of Louisiana and Texas. This
acreage is presented in the following table:

---------------
(1)  Leases are typically granted for a term of five years, during which the
     lease owner must establish a commercial production capability, or the lease
     expires. There are 5,351 acres located on leases that have commercial
     production, but the production is not on Marine's overriding royalty area
     within those leases.

The overriding royalty interest owned by Marine is a fractional interest out of
total oil and natural gas sold, and is free and clear of all operating costs.
The actual percentage interest in a lease attributable to Marine's interest
varies from lease to lease. The acreage weighted average percentage interest
attributable to Marine's interest in all of these leases is .6181%.

         Present Activities. Public records indicate that 7 wells are being
drilled on tracts in which Marine has an interest. Marine also understands from
public records that operators have designated locations for 13 additional wells.
Marine cannot assure the unitholders that these wells will be drilled and if
drilled that they will be successful.

         Difficulty in Obtaining Certain Data. Marine's only activities are the
collection and distribution of revenues from overriding royalties on certain oil
and natural gas leases in the Gulf of Mexico, pursuant to purchase agreements
between Marine's predecessors and Gulf and its transferees. The leasehold
working interests which are subject to the rights held by Marine are owned, in
most cases, in whole or in part by Chevron, or other oil and natural gas
exploration and production companies. Certain information as to reserves,
availability of oil and natural gas, average production cost (lifting cost) per
unit, undeveloped acreage, net wells and net acres, etc., with respect to the
particular leases subject to Marine's interests lies solely within the knowledge
of these concerns. Engineering data, if any, regarding these leaseholds would
have been compiled principally by or for the working interest owners of these
leaseholds and Marine believes that it will not be provided access to such
information. Because of this, it appears that unreasonable efforts and expense
would be involved in seeking to obtain all of the information required under
Item 102 of Regulation S-K and Securities Exchange Act of 1934 Industry Guide 2.


                                  LEGAL MATTERS

         Neither Marine nor MPC, nor any of their respective properties
(exclusive of properties owned by Chevron and subject to the Marine and
Tidelands license agreements), is a party to or subject to any material pending
litigation as of the date hereof.


                            UNITHOLDER VOTING MATTERS

         On December 8, 2000, the unitholders of record at the close of business
on October 24, 2000, approved an amendment to the Indenture to extend the life
of the trust beyond the original expiration date of June 1, 2001 to June 1,
2021.

         Marine is authorized to issue and has issued 2,000,000 units of
beneficial interest. On August 21, 2001, these outstanding units were held of
record by 638 unitholders.

         Marine must distribute to its unitholders all cash accumulated each
quarter, less an amount reserved for accrued liabilities and estimated future
expenses. Such distributions have been made since its inception and will
continue so long as the income from oil and natural gas royalties exceeds
administrative costs.

         Distributions fluctuate from quarter to quarter due to changes in oil
and natural gas prices and production quantities. Distributions, however, are
determined by the cash available to Marine on the determination date.

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

         Capital Resources and Liquidity. Because of the nature of Marine as a
trust entity, there is no requirement for capital; its only obligation is to
distribute to unitholders the net income actually collected. As an administrator
of oil and natural gas royalty properties, Marine collects income monthly, pays
expenses of administration, and disburses all net income collected to its
unitholders each quarter. Because all of Marine's revenues are invested in
liquid funds pending distribution, Marine does not experience liquidity
problems.

         Marine's Indenture (and the charter and by-laws of MPC) expressly
prohibits the operation of any kind of trade or business. Marine's oil and
natural gas properties are depleting assets and are not being replaced due to
the prohibition against these investments. Because of these restrictions, Marine
does not require short term or long term capital. These restrictions, along with
other factors, allow Marine to be treated as a grantor trust; thus all income
and deductions, for tax purposes, should flow through to each individual
unitholder. Marine is not a taxable entity.

         Results of Operations. Marine's revenues are derived from the oil and
natural gas production activities of unrelated parties. Marine's revenues and
distributions fluctuate from period to period based upon factors beyond Marine's
control, including without limitation the number of leases subject to Marine's
interests, the number of productive wells drilled on leases subject to Marine's
interests, the level of production over time from such wells and the prices at
which the oil and natural gas from such wells are sold. Marine believes that it
will continue to have revenues sufficient to permit distributions to be made to
unitholders for the foreseeable future, although no assurance can be made
regarding the amounts thereof. The foregoing sentence is a forward-looking
statement. Factors that might cause actual results to differ from expected
results include reductions in prices or demand for oil and natural gas, which
might then lead to decreased production; reductions in production due to
depletion of existing wells or disruptions in service, including as the result
of storm damage, blowouts or other production accidents, and geological changes
such as cratering of productive formations; expiration or release of leases
subject to Marine's interests.

         Marine's income consists primarily of oil and natural gas royalties and
is based on the value at the well of its percentage interest in oil and natural
gas sold without reduction for any of the expense of production. Value at the
well for oil is the purchasers' posted price at its receiving point onshore,
less the cost of transportation from the offshore lease to the onshore receiving
point. In general, value at the well is determined on the basis of the selling
price of oil, natural gas and other minerals produced, saved and sold, or at
wellhead prices determined by industry standards, where the selling price does
not reflect value at the well.

         Summary Review. Marine's net income for the year ended June 30, 2001
amounted to $8,482,747 or $4.24 per unit as compared to $4,743,594 or $2.37 per
unit in fiscal 2000 and $3,084,449 or $1.54 per unit in fiscal 1999. These
results include $244,250 and $514,000 realized in fiscal 2000 and 1999,
respectively, from reduction of an accounts payable provided by MPC to cover
possible refunds that may have been required upon redetermination of natural gas
prices for royalty payments in prior periods.

         These results also include income from Marine's equity interest in
Tidelands which amounted to $574,755 for fiscal 2001, $318,072 for fiscal 2000
and $328,085 for fiscal 1999. Income from Tidelands contributed approximately 7%
of Marine's royalty income for fiscal 2001 as compared to 6% and 10% of Marine's
royalty income for fiscal 2000 and 1999, respectively.

         Marine's administrative expenses increased to approximately $241,000
from approximately $180,000 experienced in the previous year. This increase was
substantially due to increased legal, accounting and other expenses resulting
from the solicitation of the unitholders consent to extend the life of the Trust
for another 20 years to June 1, 2021.

         Interest income increased to approximately $120,000 from approximately
$92,000 realized in the previous year due to an increase in funds temporarily on
deposit resulting from the increased revenue from oil and natural gas royalties.



                                       8

         Marine believes that the drilling and work-over program of the
operating companies, which has resulted in an average of 80 new completions over
the past three years, is primarily responsible for maintaining the number of
producing wells at an average of 340 oil and natural gas wells for the past
three fiscal years.

         The following table and related discussion and analysis shows the
royalty income, the net quantities sold, and the average price received for oil
and natural gas during the past three years excluding Marine's equity interest
in Tidelands and the $244,250 and $514,000 realized in fiscal 2000 and fiscal
1999, respectively, from the reduction of the previously established accounts
payable for possible royalty over-payments that management no longer deemed
required.

         Oil and Gas Royalties - 2001 and 2000: Revenue from oil royalties
amounted to $3,207,362 in fiscal 2001, an increase of 41% over the $2,275,447
realized in fiscal 2000. The average price of a barrel of oil increased 16% to
$28.50 and production increased 21% to 112,554 barrels. Please refer to the
table in the previous section.

         Revenue from natural gas royalties amounted to $4,854,958, an increase
of 142% over the $2,006,664 realized in fiscal 2000. The average price of a
thousand cubic feet (mcf) of natural gas increased 102% to $5.00 and production
increased 20% to 971,880 mcf. Please refer to the table in the previous section.

         Oil and Gas Royalties -- 2000 and 1999: During fiscal 2000, Marine
received approximately 53% of its royalty income from the sale of oil and 47%
from the sale of natural gas. Income from such oil and natural gas royalties in
fiscal 2000 increased approximately 84% from fiscal 1999.

         Oil royalties during fiscal 2000 in the amount of $2,275,447 were 215%
more than oil royalties received in fiscal 1999 in the amount of $721,782, due
to an increase in the quantity of oil sold and in the average price received.

         Natural gas royalties during fiscal 2000 in the amount of $2,006,664
were 25% higher than natural gas royalties received in fiscal 1999 in the amount
of $1,604,772. The increase was due to an increase in the price received that
was partially offset by a decrease in the quantity of natural gas sold.

                          INDEPENDENT AUDITORS' REPORT

The Trustee
Marine Petroleum Trust:

         We have audited the accompanying consolidated balance sheets of Marine
Petroleum Trust and subsidiary as of June 30, 2001 and 2000 and the related
consolidated statements of income and undistributed income and cash flows for
each of the years in the three-year period ended June 30, 2001. These financial
statements are the responsibility of the Trust's management. Our responsibility
is to express an opinion on these financial statements based on our audits.

         We conducted our audits in accordance with auditing standards generally
accepted in the United States of America. 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 consolidated financial statements referred to above
present fairly, in all material respects, the financial position of Marine
Petroleum Trust and subsidiary as of June 30, 2001 and 2000 and the results of
their operations and their cash flows for each of the years in the three-year
period ended June 30, 2001, in conformity with accounting principles generally
accepted in the United States of America.

("Chevron"), a subsidiary of Chevron Corporation, in certain areas of the Gulf
of Mexico prior to January 1, 1980.

         Marine must distribute all income, after paying its liabilities and
obligations, to the unitholders during the months of March, June, September and
December each year. It cannot invest any of its money for any purpose and cannot
engage in a trade or business.

         A Louisiana trust can only exist for a short period of time; therefore,
the unitholders assigned their contract rights off-shore of Louisiana to Marine
Petroleum Corporation, a wholly-owned subsidiary of Marine, ("MPC") reserving a
98% net profits interest to themselves. The net profits interest contract was
transferred to Marine along with the other properties. Marine is authorized to
pay expenses of MPC should it be necessary.

         Marine is to continue until June 1, 2021, or until such later date as
holders of the units owning a majority of the outstanding units may designate,
but in any event, not more than 20 years from such designation. However, the
unitholders owning eighty percent (80%) of the outstanding units may terminate
the trust on any date.

     (b) Principles of Consolidation

         The consolidated financial statements include Marine and its
wholly-owned subsidiary, MPC. All material intercompany accounts and
transactions have been eliminated in consolidation.

     (c) Producing Oil and Gas Properties

         At the time Marine was established, no determinable market value was
available for the assets transferred to Marine; consequently, nominal values
were assigned. Accordingly, no allowance for depletion has been computed.

         All income from oil and natural gas royalties relate to proved
developed oil and natural gas reserves.

     (d) Undistributed Income

         Marine's indenture agreement provides that the corporate trustee is to
distribute all cash in the trust, less an amount reserved for the payment of
accrued liabilities and estimated future expenses, to unitholders of record on
the 28th day of March, June, September and December of each year. If the 28th
falls on a Saturday, Sunday or legal holiday, the distribution is payable on the
immediately preceding business day. Undistributed income includes $974,167 and
$855,397 applicable to MPC at June 30, 2001 and 2000, respectively.

     (e) Federal Income Taxes

         No provision has been made for Federal income taxes on Marine's income
since such taxes are the liability of the unitholders. Federal income taxes have
been provided on the income of MPC, excluding the 98% net profits interest to be
distributed to Marine and deducting statutory depletion.

                         THREE YEARS ENDED JUNE 30, 2001

     (f) Credit Risk Concentration and Cash Equivalents

         Financial instruments which potentially subject Marine and MPC to
concentrations of credit risk are primarily investments in cash equivalents and
receivables. Marine and MPC place their cash investments with financial
institutions or companies that management considers credit worthy and limit the
amount of credit exposure from any one financial institution or company. Marine
has not experienced significant problems collecting its receivables in the past.

         Marine and MPC had cash equivalents of $2,480,267 and $1,611,902 at
June 30, 2001 and 2000, respectively, which consisted of money market accounts
and money market mutual funds. For purposes of the statements of cash flows,
Marine considers all investments with initial maturities of three months or less
to be cash equivalents.

     (g) Statements of Cash Flows

         MPC made Federal income tax payments of $25,625, $12,380 and $4,815
during the years ended June 30, 2001, 2000 and 1999, respectively.

     (h) Fair Value of Financial Instruments

         Marine and MPC define the fair value of a financial instrument as the
amount at which the instrument could be exchanged in a current transaction
between willing parties. The carrying value of cash equivalents, oil and natural
gas royalties receivable, receivables from affiliates, accounts payable, and
taxes payable approximate fair value because of the short maturities of those
instruments.

     (i) Use of Estimates

         Management of Marine and MPC has made a number of estimates and
assumptions relating to the reporting of assets and liabilities and the
disclosure of contingent assets and liabilities to prepare these financial
statements in conformity with generally accepted accounting principles. Actual
results could differ from those estimates.

     (j) Income Per Unit

         Income per unit is calculated by dividing net income by the weighted
average number of units of beneficial interest outstanding during the period.

     (k) Significant Royalty Sources

         Royalty revenue received by Marine from producers is summarized as
follows:

(3) OVERPAID ROYALTIES

         During fiscal years 2000 and 1999, MPC determined that $244,250 and
$514,000, respectively, of the previously-established accounts payable for
possible royalty overpayments was no longer deemed required. Accordingly, during
these fiscal years, MPC reduced accounts payable and increased income before
federal income taxes by such amounts.
