ITEM 1. BUSINESS

         Organization. Marine Petroleum Trust ("Marine") is a royalty trust that
was created in 1956 under the laws of the State of Texas. Marine is not
permitted to engage in any business activity because 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 are now 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 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 the 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 by the oil and natural gas industry, and we sometimes refer to
them as overriding royalty interests in this annual report. All production and
marketing functions are conducted by the working interest owners of the leases.
Revenues from 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 leases 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. Tidelands' indenture provides that
the corporate trustee is to distribute all cash in the trust, less an amount
reserved for payment of accrued liabilities and estimated future expenses, to
unitholders of record on the last business day of March, June, September and
December of each year. Such payments are to be made within 15 days after the
record date. Distributable income is paid from the unconsolidated account
balances of Tidelands. Distributable income is comprised of (i) royalties from
offshore Texas leases owned directly by Tidelands, plus (ii) 95% of the
overriding royalties received by the subsidiary that are paid to Tidelands on a
quarterly basis, less (iii) administrative expenses of Tidelands.

         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 wellhead 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 April 30, 2001, Chevron, Elf or their assigns had acquired a total of eight
(8) leases. At June 30,

                                       -2-
<PAGE>
2003, five of Tidelands' assigned leases contained producing wells and had paid
out their $1,500,000 production payment. Tidelands' royalty interest on four of
the five leases was 4.17% at June 30, 2003. On the fifth lease Tidelands'
overriding royalty interest is 1.0416%. Two assigned leases do not contain any
producing wells. These leases have not paid $1,500,000 in production payments.

         Presently, the leases subject to Marine's interests cover 272,156 gross
acres (including Tidelands' interest in 27,948 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. Leases may also be abandoned by the working interest
owner due to the failure to discover sufficient reserves to make development
economically worthwhile. In addition, the federal government may force
termination of a lease if the working interest owner fails to fully develop a
lease once it is acquired.

         For the year ended June 30, 2003, approximately 45% of Marine's royalty
revenues were attributable to the sale of oil and approximately 55% 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. Over 90% of Marine's revenues for each of the
past three years was paid by five working interest owners. The percentage
received from these five working interest owners for each of the past three
years is presented in the following table:

    Arco.

(2) Includes $187,407 paid by Vastar and $197,641 paid by Arco after Arco
    acquired Vastar.

In addition, Marine's revenues from its equity interest in Tidelands accounted
for approximately 8%, 5% and 7% of Marine's revenue for the years ended June 30,
2003, 2002 and 2001, respectively. Tidelands has reported that royalty revenues
from Burlington Resources, Dunhill Resources, Inc., Pennzenergy Exploration and
Production Company and Devon Energy Production Company accounted for a
substantial portion of Tidelands' royalty revenue for the years ended December
31, 2002, 2001 and 2000.

         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 Ray Bell, its president,
treasurer and director, to perform certain management, financial and
administrative services for Marine. Except for Mr. Bell, all officers and
directors of MPC serve without compensation. See "Management and Principal
Unitholders."

         All aspects of Marine's operations are conducted by third parties. Oil
and natural gas companies that lease tracts subject to Marine's interests
conduct the production and sale of oil and natural gas and the calculation of
royalty payments to Marine. 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 MPC and Tidelands' wholly-owned subsidiary corporation,
Tidelands Royalty Trust "B" Corporation. The cost of this office facility is
shared by MPC and Tidelands Royalty Trust "B" Corporation proportionately based
on each entity's gross income.


                                       -3-
<PAGE>

         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.

<PAGE>

ITEM 2. 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 that 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. Similarly, Tidelands does not have access to the engineering data
necessary to make an estimate of the proved oil and natural gas reserves
attributable thereto. See also "Difficulty in Obtaining Certain Data" below.

         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,
2003, 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 interest in Tidelands) 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, there were approximately 381 active wells subject to Marine's interests,
some of which contained multiple completions. Approximately 167 wells were
classified as oil wells and approximately 214 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.

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 3,958 acres located on leases that have commercial
production, but the production is not on Marine's overriding royalty area within
those leases.

(2) The primary term is five (5) years.

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 .60271%.

         Present Activities. Public records indicate that 5 wells are either
being drilled, re-drilled or worked over on tracts that Marine has an interest
in. Public records indicate that operators have designated locations for 9
additional operations. There is no assurance that these wells will be drilled,
and if they are 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 that 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, 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. In the past, Marine has asked for such information
and was told it is not entitled to receive such information. Marine believes
that it will not be provided access to such information in the future.
Therefore, 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.

         Marine is authorized to issue and has issued 2,000,000 units of
beneficial interest. On June 30, 2003, these outstanding units were held of
record by 584 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 are determined
by the cash available to Marine on the determination date.

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
        RESULTS OF OPERATIONS

         Critical Accounting Policies. As an overriding royalty owner, actual
production results are not known to us until reported by the operator, which
could be a period of 60-90 days later than the actual month of production. To
comply with accounting principles generally accepted in the United States of
America, we must estimate earned but unpaid royalty from this production. To
estimate this amount, we utilize historical information based on the latest
production reports from the individual leases and current average prices as
reported for oil by Chevron USA and the spot market price for natural gas
delivered at the Henry Hub in Louisiana for the period under report.

         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 and is subject to numerous factors. 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;
and the 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 expenses of production. "Value at the
well" for oil means the purchasers' posted price at its receiving point onshore,
less the cost of transportation from the offshore lease to the onshore receiving
point.

         Summary Review. Marine's net income for the year ended June 30, 2003
amounted to $5,158,676 or $2.58 per unit as compared to $4,847,485 or $2.42 per
unit in fiscal 2002 and $8,482,747 or $4.24 per unit in fiscal 2001.

         These results also include income from Marine's equity interest in
Tidelands which amounted to $439,698 for fiscal 2003, $234,945 for fiscal 2002,
and $574,755 for fiscal 2001. Income from Tidelands contributed approximately 9%
of Marine's royalty income for fiscal 2003 as compared to 5% and 7% of Marine's
royalty income for fiscal 2002 and 2001, respectively.

         Marine's administrative expenses decreased to approximately $218,000 in
fiscal 2003 from approximately $231,000 spent in fiscal 2002. This decrease was
substantially due to decreased legal, accounting and other expenses.

         Interest income decreased to approximately $35,000 in fiscal 2003 from
approximately $52,000 realized in fiscal 2002 due to a decrease in the rate of
interest paid.

         Marine believes that the drilling and work-over program of the
operating companies has added to the life of well revenue. The following table
shows the number of new wells drilled and the number of producing wells for the
past three fiscal years.

         Oil and Gas Royalties - 2002 and 2001: Revenue from oil royalties
amounted to $2,647,623 in fiscal 2002, a decrease of 17% over the $3,207,362
realized in fiscal 2001. The average price of a barrel of oil decreased 18% to
$23.34 and production increased 0.8% to 113,424 barrels. Please refer to the
table above.

         Revenue from natural gas royalties amounted to $2,124,195, a decrease
of 56% from the $4,854,958 realized in fiscal 2002. The average price of a
thousand cubic feet (mcf) of natural gas decreased 43% to $2.83 and production
decreased 23% to 749,771 mcf. Please refer to the table above.

         Oil and Gas Royalties - 2003 and 2002: Revenue from oil royalties
amounted to $2,212,252 in fiscal 2003, a decrease of 16% over the $2,647,623
realized in fiscal 2002. The average price of a barrel of oil increased 6% to
$24.64 and production decreased 21% to 89,792 barrels. Please refer to the table
above.

         Revenue from natural gas royalties amounted to $2,696,761, an increase
of 27% over the $2,124,195 realized in fiscal 2002. The average price of a
thousand cubic feet (mcf) of natural gas increased 63% to $4.60 and production
decreased 22% to 585,732 mcf. Please refer to the table above.

         A tropical storm and a hurricane in the Gulf of Mexico interrupted
production and damaged production facilities resulting in decreased production
during the last nine months of the fiscal year ending June 30, 2003.

         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.

         Marine does not currently have any long term contractual obligations.

                          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, 2003 and 2002 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, 2003. 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, 2003 and 2002 and the results of
their operations and their cash flows for each of the years in the three-year
period ended June 30, 2003, in conformity with accounting principles generally
accepted in the United States of America.

                                                     /s/ KPMG LLP

                      MARINE PETROLEUM TRUST AND SUBSIDIARY

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                         THREE YEARS ENDED JUNE 30, 2003

(1) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

     (a) General

         The Marine Petroleum Trust ("Marine") was established on June 1, 1956
with the transfer of property to Marine consisting of certain contract rights,
units of beneficial interest and common stock in exchange for units of
beneficial interest in Marine. The contract rights entitled Marine to receive a
..0075 overriding royalty interest in oil, natural gas and other mineral
leasehold interests acquired by Gulf Oil Corporation, now Chevron U.S.A., Inc.
("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. Marine and its subsidiary cannot engage in a trade or
business. Funds held by the subsidiary pending distribution to Marine are
invested in U.S. Treasury and agency bonds.

         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 $1,004,053 and
$983,594 applicable to MPC at June 30, 2003 and 2002, 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.

                                      -18-

                         THREE YEARS ENDED JUNE 30, 2003

         Income Taxes

         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. MPC uses the cash method of reporting for federal income taxes.

         At June 30, 2003 and 2002, deferred tax assets and liabilities were as
follows:

<TABLE>

                                                          June 30, 2003   June 30, 2002

<S>                                                       <C>             <C>
Deferred tax assets
     Net operating loss carryforward ..................      $ 3,400         $ 3,936
Deferred tax liabilities
     Income not yet recognized for income taxes .......       (3,400)         (3,936)
                                                             -------         -------
Net deferred tax liability ............................      $    --         $    --
                                                             =======         =======
</TABLE>

         MPC had a net operating loss carryforward of approximately $17,000 at
June 30, 2003, which does not expire until 2022.

         The primary difference between the effective tax rate of the Trust and
the statutory tax rate is the fact that only MPC income, excluding the 98% net
profits interest, is subject to federal income tax.

     (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,
U.S. Treasury and agency bonds 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 and investments in U.S. Treasury
and agency bonds of $2,049,720 and $1,646,736 at June 30, 2003 and 2002,
respectively, which consisted of money market accounts, U.S. Treasury and agency
bonds, 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 no Federal income tax payments in the year ended June 30, 2003
and made payments of $15,200, and $25,625 during the years ended June 30, 2002
and 2001, 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.

         U.S. Treasury and agency bonds held to maturity are valued at amortized
cost.

     (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:

(2) INVESTMENT IN AND RECEIVABLES FROM AFFILIATE - TIDELANDS ROYALTY TRUST "B"

         At June 30, 2003 and 2002, Marine owned 32.63% of the outstanding units
of interest in Tidelands Royalty Trust "B" ("Tidelands"). The 452,366 units
owned by Marine had a quoted market value of $3,008,234 and $1,538,044 at June
30, 2003 and 2002, respectively.

         Marine and Tidelands share certain common costs which are allocated
based on their respective net revenues.

         The investment in affiliate is accounted for by the equity method. The
following summarizes changes in this account for 2003 and 2002.

unitholder.

1.       I have reviewed this annual report on Form 10-K of Marine Petroleum
         Trust;

2.       Based on my knowledge, this annual report does not contain any untrue
         statement of a material fact or omit to state a material fact necessary
         to make the statements made, in light of the circumstances under which
         such statements were made, not misleading with respect to the period
         covered by this annual report;

3.       Based on my knowledge, the financial statements, and other financial
         information included in this annual report, fairly present in all
         material respects the financial condition, results of operations and
         cash flows of the registrant as of, and for, the periods presented in
         this annual report;

4.       The registrant's Trustee and I are responsible for establishing and
         maintaining disclosure controls and procedures (as defined in Exchange
         Act Rules 13a-15(e) and 15d-15(e)) for the registrant and we have:

         a)       designed such disclosure controls and procedures, or caused
                  such disclosure controls and procedures to be designed under
                  our supervision, to ensure that material information relating
                  to the registrant, including its consolidated subsidiaries, is
                  made known to us by others within those entities, particularly

                  controls and procedures, as of the end of the period covered
                  by this annual report based on such evaluation; and

         c)       disclosed in this annual report any change in the registrant's
                  internal control over financial reporting that occurred during
                  the registrant's most recent fiscal quarter (the registrant's
                  fourth fiscal quarter in the case of an annual report) that
                  has materially affected, or is reasonably likely to materially
                  affect, the registrant's internal control over financial
                  reporting; and

5.       The registrant's Trustee and I have disclosed, based on our most recent
         evaluation of internal control over financial reporting, to the
         registrant's auditors and the audit committee of the registrant's board
         of directors (or persons performing the equivalent functions):

         a)       all significant deficiencies and material weaknesses in the
                  design or operation of internal control over financial
                  reporting which are reasonably likely to adversely affect the
                  registrant's ability to record, process, summarize and report
                  financial information; and

         b)       any fraud, whether or not material, that involves management
                  or other employees who have a significant role in the
                  registrant's internal control over financial reporting; and

In giving the certifications in paragraphs 4 and 5 above, I have relied to the

interest owners.
