MARINE PETROLEUM TRUST AND SUBSIDIARY

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

December 31, 2014

(Unaudited)

Note 1. Accounting Policies

The financial statements herein include the financial statements of Marine Petroleum Trust (the “Trust”) and its wholly-owned subsidiary, Marine Petroleum Corporation (“MPC,” and collectively with the Trust, “Marine”). The financial statements are condensed and consolidated and should be read in conjunction with Marine’s Annual Report on Form 10-K for the fiscal year ended June 30, 2014. The financial statements included herein are unaudited, but in the opinion of Southwest Bank (the “Trustee”), the Trustee of the Trust, they include all adjustments necessary for a fair presentation of the results of operations for the periods presented. Operating results for the interim periods reported herein are not necessarily indicative of the results that may be expected for the fiscal year ending June 30, 2015.

Note 2. Basis of Accounting

The financial statements of Marine are prepared on the modified cash basis method and are not intended to present Marine’s financial position and results of operations in conformity with generally accepted accounting principles in the United States (“GAAP”). Under the modified cash basis method the financial statements of Marine differ from financial statements prepared in conformity with GAAP because of the following:

The modified cash basis method of accounting corresponds to the accounting principles permitted for royalty trusts by the U.S. Securities and Exchange Commission (the “SEC”), as specified by Staff Accounting Bulletin Topic 12:E, Financial Statements of Royalty Trusts.

Note 3. Distributable Income

The Trust’s Indenture (the “Indenture”) provides that the 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 28^th day of March, June, September and December of each year. If the 28^th day falls on a Saturday, Sunday or legal holiday, the payments are to be made on the immediately succeeding business day.

As stated under “Note 1. Accounting Policies” above, the financial statements in this Quarterly Report on Form 10-Q are the condensed and consolidated financial statements of the Trust and MPC. However, distributable income is paid from the account balances of the Trust. Distributable income is comprised of (i) royalties from offshore Texas leases owned directly by the Trust, (ii) 98% of the royalties received from offshore Louisiana leases owned by MPC, which are retained by and delivered to the Trust on a quarterly basis, (iii) cash distributions from the Trust’s interest in Tidelands Royalty Trust “B” (“Tidelands”), a separate publicly traded royalty trust, (iv) dividends paid by MPC, less (v) administrative expenses incurred by the Trust. Distributions fluctuate from quarter to quarter primarily due to changes in oil and natural gas prices and production quantities.

Note 4. Investment in Affiliate — Tidelands Royalty Trust “B”

At December 31, 2014 and 2013, the Trust owned 32.6% of the outstanding units of beneficial interest in Tidelands.

The following summary financial statements have been derived from the unaudited condensed consolidated financial statements of Tidelands:

TIDELANDS CONDENSED CONSOLIDATED STATEMENTS OF DISTRIBUTABLE INCOME

Tidelands is a reporting company under the Securities Exchange Act of 1934, as amended, that has filed its Annual Report on Form 10-K for the fiscal year ended December 31, 2013. Tidelands has not yet filed its financial statements for the fiscal year ended December 31, 2014 with the SEC. Therefore, the Condensed Consolidated Statements of Distributable Income of Tidelands have been taken from Tidelands’ Quarterly Report on Form 10-Q for the period ended September 30, 2014, the latest period for which such information is publicly available. Reference should be made to Tidelands’ public filings for current information concerning Tidelands’ financial position and results of operations.

Item 2. Trustee’s Discussion and Analysis of Financial Condition and Results of Operations

Organization

Marine Petroleum Trust (the “Trust”) is a royalty trust that was created in 1956 under the laws of the State of Texas. Southwest Bank, an independent state bank chartered under the laws of the State of Texas and headquartered in Fort Worth, Texas, serves as corporate trustee (the “Trustee”). The Trust’s Indenture (the “Indenture”) provides that the term of the 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. The Trust 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 between the Trust’s predecessors and Gulf Oil Corporation (“Gulf”). As a result of various transactions that have occurred since 1956, these interests now are held by Chevron Corporation (“Chevron”) and its assignees. The Trust holds title to interests in properties that are situated offshore of Texas.

The Trust’s wholly-owned subsidiary, Marine Petroleum Corporation (“MPC,” and collectively with the Trust, “Marine”), holds title to interests in properties that are situated offshore of Louisiana because at the time the Trust was created, trusts could not hold these interests under Louisiana law. MPC is prohibited from engaging in a trade or business and only takes those actions that are necessary for the administration and liquidation of its properties.

Marine’s rights are generally referred to as overriding royalty interests in the oil and natural gas industry. An overriding royalty interest is created by an assignment by the owner of a working interest in an oil or natural gas lease. The royalty rights associated with an overriding royalty interest terminate when the underlying lease terminates. All production and marketing functions are conducted by the working interest owners of the leases. Income from overriding royalties is paid to Marine either (i) on the basis of the selling price of oil, natural gas and other minerals produced, saved or 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.

The Trustee assumes that some units of beneficial interest are held by middlemen, as such term is broadly defined in U.S. Treasury Regulations (and includes custodians, nominees, certain joint owners and brokers holding an interest for a customer in street name). Therefore, the Trustee considers the Trust to be a widely held fixed investment trust (“WHFIT”) for U.S. federal income tax purposes. Accordingly, the Trust will provide tax information in accordance with applicable U.S. Treasury Regulations governing the information reporting requirements of the Trust as a WHFIT. The Trustee will provide the required information and the contact information for the Trustee is below:

Each unitholder should consult its own tax advisor for compliance with U.S. federal income tax laws and regulations.

Liquidity and Capital Resources

As stated in the Indenture, there is no requirement for capital due to the limited purpose of the Trust. The Trust’s only obligation is to distribute the distributable income that is actually collected to unitholders. As an administrator of oil and natural gas royalty interests, the Trust collects royalties monthly, pays administrative expenses and disburses all net royalties that are collected to its unitholders each quarter.

The Indenture (and MPC’s charter and by-laws) expressly prohibits the operation of any kind of trade or business. The Trust’s oil and natural gas properties are depleting assets that are not being replaced due to the prohibition against investments. These restrictions, along with other factors, allow the Trust to be treated as a

grantor trust. As a grantor trust, all income and deductions for state and U.S. federal income tax purposes generally flow through to each individual unitholder. The State of Texas imposes a franchise tax, but the Trust does not believe that it is subject to the franchise tax because at least 90% of its income is from passive sources. Please see Marine’s Annual Report on Form 10-K for the fiscal year ended June 30, 2014 for further information. MPC is a taxable entity that pays state and U.S. federal income taxes and state franchise taxes. However, MPC’s income specifically excludes 98% of the oil and natural gas royalties collected by MPC, which are retained by and delivered to the Trust because of the Trust’s net profits interest.

The Leases

Marine relies on public records for information regarding drilling and workover operations. The public records available up to the date of this report indicate that there were no new well completions made during the three months ended December 31, 2014 on leases in which Marine has an interest. As of February 1, 2015, public records also indicated that there were no wells in the process of being drilled or recompleted on other leases in which Marine has an interest.

Marine holds an overriding royalty interest that is equal to three-fourths of one percent of the working interest and is calculated on the value at the well of any oil, natural gas or other minerals produced and sold from 55 leases covering 199,868 gross acres located in the Gulf of Mexico. Marine’s overriding royalty interest applies only to existing leases and does not apply to any new leases that Chevron may acquire. The Trust also owns a 32.6% interest in Tidelands Royalty Trust “B” (“Tidelands”). Tidelands has an overriding royalty interest in four oil and natural gas leases covering 17,188 gross acres in the Gulf of Mexico. As a result of this ownership, the Trust receives periodic distributions from Tidelands.

Critical Accounting Policies and Estimates

In accordance with the Staff Accounting Bulletin Topic 12:E, Financial Statements of Royalty Trusts, Marine uses the modified cash basis method of accounting. Under this accounting method, royalty income is recorded when received, and distributions to unitholders are recorded when declared by the Trustee of the Trust. Expenses of Marine (including accounting, legal, other professional fees, trustees’ fees and out-of-pocket expenses) are recorded on an actual paid basis. Marine also reports distributable income instead of net income under the modified cash basis method of accounting. Cash reserves are permitted to be established by the Trustee for certain contingencies that would not be recorded under generally accepted accounting principles in the United States.

Marine did not have any changes in its critical accounting policies or estimates during the three months ended December 31, 2014. Please see Marine’s Annual Report on Form 10-K for the fiscal year ended June 30, 2014 for a detailed discussion of its critical accounting policies.

New Accounting Pronouncements

There are no new pronouncements that are expected to have a significant impact on Marine’s financial statements.

General

Marine’s royalty income is derived from the oil and natural gas production activities of third parties. Marine’s royalty income fluctuates from period to period based upon factors beyond Marine’s control, including, without limitation, the number of productive wells drilled and maintained on leases that are subject to Marine’s interest, the level of production over time from such wells and the prices at which the oil and natural gas from such wells are sold.

Important aspects of Marine’s operations are conducted by third parties. Marine’s royalty income is dependent on the operations of the working interest owners of the leases on which Marine has an overriding royalty interest. The oil and natural gas companies that lease tracts subject to Marine’s interests are responsible for the production and sale of oil and natural gas and the calculation of royalty payments to Marine. The only obligation of the working interest owners to Marine is to make monthly overriding royalty payments that reflect Marine’s interest in the oil and natural gas sold. Marine’s distributions are processed and paid by its transfer agent, American Stock Transfer & Trust Company, LLC.

Table of Contents

The volume of oil and natural gas produced and the selling prices of such oil and natural gas are the primary factors in calculating overriding royalty payments. Production is affected by the natural production decline of the producing wells, the number of new wells drilled and the number of existing wells that are re-worked and placed back in production on the leases. Production from existing wells is anticipated to decrease in the future due to normal well depletion. The operators do not provide Marine with information regarding future drilling or re-working operations that could impact the oil and natural gas production from the leases for which Marine has an overriding royalty interest.

Summary of Operating Results

Distributable income per unit for the six months ended December 31, 2014 decreased to $0.65 as compared to $0.81 for the comparable period in 2013. Distributions per unit amounted to $0.66 per unit for the six months ended December 31, 2014, a decrease from distributions of $0.73 per unit for the comparable period in 2013. During the six months ended December 31, 2014, the difference between distributable income per unit and distributions per unit resulted from timing differences between the closing of the financial statements and the determination date of the distribution amount to unitholders.

For the six months ended December 31, 2014, excluding the Trust’s interest in Tidelands, oil production decreased to 10,473 barrels (bbls) from 14,097 bbls and natural gas production increased to 53,286 thousand cubic feet (mcf) from 52,791 mcf as compared to the comparable period in 2013. For the six months ended December 31, 2014, excluding the Trust’s interest in Tidelands, the average price realized for oil decreased to $101.02 per bbl as compared to the price of $101.82 realized for the comparable period in 2013 and the average price realized for natural gas increased to $5.78 per mcf as compared to the average price of $4.60 realized for the comparable period in 2013.

The following table presents the net production quantities of oil and natural gas and distributable income and distributions per unit for the last six quarters.

Forward-Looking Statements

The statements discussed in this Quarterly Report on Form 10-Q regarding Marine’s future financial performance and results, and other statements that are not historical facts, are forward-looking statements as defined in Section 27A of the Securities Act of 1933, as amended and Section 21E of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). This report uses the words “anticipate,” “believe,” “budget,” “continue,” “estimate,” “expect,” “intend,” “may,” “plan,” or other similar words to identify forward-looking statements. You should read statements that contain these words carefully because they discuss future expectations, contain projections of Marine’s financial condition, and/or state other “forward-looking” information. Actual results may differ from expected results because of: reductions in price or demand for oil and natural gas, which might then lead to decreased production; reductions in production due to the depletion of existing wells or disruptions in service, which may be caused by storm damage to production facilities, blowouts or other production accidents, or geological changes such as cratering of productive formations; changes in regulations; general economic conditions; actions and policies of petroleum-producing nations; other changes in domestic and international energy markets; the resignation of the Trustee; and the expiration, termination or release of leases subject to Marine’s interests. Additional risks are set forth in Marine’s Annual Report on Form 10-K for the fiscal year ended June 30, 2014. Events may occur in the future that Marine is unable to accurately predict or over which it has no control. If one or more of these uncertainties materialize, or if underlying assumptions prove incorrect, actual outcomes may vary materially from those forward-looking statements included in this Quarterly Report on Form 10-Q. Except as required by applicable securities laws, Marine does not undertake any obligation to update or revise any forward-looking statements.
