GLOSSARY OF CERTAIN OIL AND NATURAL GAS TERMS

        In this Form 10-K the following terms have the meanings specified below.

        Bbl—One stock tank barrel, or 42 U.S. gallons liquid volume, of crude oil or other liquid hydrocarbons.

        Boe—One stock tank barrel of oil equivalent, computed on an approximate energy equivalent basis that one Bbl of crude oil equals six Mcf of natural gas and one Bbl of crude oil equals 1.54 Bbls of natural gas liquids.

        Btu or British Thermal Unit—The quantity of heat required to raise the temperature of one pound of water one degree Fahrenheit.

        Completion—The installation of permanent equipment for the production of oil or natural gas, or, in the case of a dry well, the reporting to the appropriate authority that the well has been abandoned.

        Developed Acreage—The number of acres that are allocated or assignable to productive wells or wells capable of production.

        Development Well—A well drilled within the proved area of an oil or natural gas reservoir to the depth of a stratigraphic horizon known to be productive.

        Estimated Future Net Revenues—Also referred to as "estimated future net cash flows." The result of applying current prices of oil, natural gas and natural gas liquids to estimated future production from oil, natural gas and natural gas liquids proved reserves, reduced by estimated future expenditures, based on current costs to be incurred, in developing and producing the proved reserves, excluding overhead.

        Farm-in or Farm-out Agreement—An agreement under which the owner of a working interest in an oil or natural gas lease typically assigns the working interest or a portion of the working interest to another party who desires to drill on the leased acreage. Generally, the assignee is required to drill one or more wells in order to earn its interest in the acreage. The assignor usually retains a royalty or reversionary interest in the lease. The interest received by an assignee is a "farm-in" while the interest transferred by the assignor is a "farm-out."

        Field—An area consisting of a single reservoir or multiple reservoirs all grouped on or related to the same individual geological structural feature and/or stratigraphic condition. There may be two or more reservoirs in a field that are separated vertically by intervening impervious, strata, or laterally by local geologic barriers, or by both. Reservoirs that are associated by being in overlapping or adjacent fields may be treated as a single or common operational field. The geological terms structural feature and stratigraphic condition are intended to identify localized geological features as opposed to the broader terms of basins, trends, provinces, plays, areas-of-interest, etc.

        Gross Acres or Gross Wells—The total acres or wells, as the case may be, in which a working interest is owned.

        MBbl—One thousand barrels of crude oil or other liquid hydrocarbons.

        MBoe—One thousand barrels of oil equivalent.

        Mcf—One thousand standard cubic feet of natural gas.

        MMBbls—One million barrels of crude oil or other liquid hydrocarbons.

        MMBoe—One million barrels of oil equivalent.

        MMcf—One million standard cubic feet of natural gas.

        Net Acres or Net Wells—The sum of the fractional working interests owned in gross acres or wells, as the case may be.

        Net Profits Interest—A nonoperating interest that creates a share in gross production from an operating or working interest in oil and natural gas properties. The share is measured by net profits from the sale of production after deducting costs associated with that production.

        Net Revenue Interest—An interest in all oil, natural gas and natural gas liquids produced and saved from, or attributable to, a particular property, net of all royalties, overriding royalties, net profits interests, carried interests, reversionary interests and any other burdens to which the person's interest is subject.

2

        NGLs—Natural gas liquids.

        Plugging and Abandonment—Activities to remove production equipment and seal off a well at the end of a well's economic life.

        Proved Developed Non-Producing Reserves—Proved developed reserves expected to be recovered from zones behind casing in existing wells.

        Proved Developed Oil and Gas Reserves—Proved Oil and Gas Reserves that can be expected to be recovered:

(A)

through existing wells with existing equipment and operating methods or in which the cost of the required equipment is relatively minor compared to the cost of a new well; and



(B)

through installed extraction equipment and infrastructure operational at the time of the reserves estimate if the extraction is by means not involving a well.

        Proved Developed Producing Reserves—Proved developed reserves that are expected to be recovered from completion intervals currently open in existing wells and capable of production to market.

        Proved Oil and Gas Reserves—Under rules of the Securities and Exchange Commission for fiscal years ending on or after December 31, 2009, proved oil and gas reserves are defined as those quantities of oil and gas that, by analysis of geoscience and engineering data, can be estimated with reasonable certainty to be economically producible—from a given date forward, from known reservoirs, and under existing economic conditions, operating methods, and government regulations—prior to the time at which contracts providing the right to operate expire, unless evidence indicates that renewal is reasonably certain, regardless of whether deterministic or probabilistic methods are used for the estimation. The project to extract the hydrocarbons must have commenced or the operator must be reasonably certain that it will commence the project within a reasonable time.

(A)

The area of a reservoir considered as proved includes: (i) the area identified by drilling and limited by fluid contacts, if any, and (ii) adjacent undrilled portions of the reservoir that can, with reasonable certainty, be judged to be continuous with it and to contain economically producible oil or gas on the basis of available geoscience and engineering data.



(B)

In the absence of data on fluid contacts, proved quantities in the reservoir are limited by the lowest known hydrocarbons, as seen in a well penetration unless geoscience, engineering, or performance data and reliable technology establishes a lower contact with reasonable certainty.



(C)

Where direct observation from well penetrations has defined a highest known oil elevation and the potential exists for an associated gas cap, proved oil reserves may be assigned in the structurally higher portions of the reservoir only if geoscience, engineering, or performance data and reliable technology establish the higher contact with reasonable certainty.



(D)

Reserves that can be produced economically through application of improved recovery techniques (including, but not limited to, fluid injection) are included in the proved classification when (i) successful testing by a pilot project in an area of the reservoir with properties no more favorable than in the reservoir as a whole, the operation of an installed program in the reservoir or an analogous reservoir, or other evidence using reliable technology establishes the reasonable certainty of the engineering analysis on which the project or program was based and (ii) the project has been approved for development by all necessary parties and entities, including governmental entities.



(E)

Existing economic conditions include prices and costs at which economic producibility from a reservoir is determined. The price is the average price during the 12-month period prior to

3

the ending date of the period covered by the report, determined as an unweighted arithmetic average of the first-day-of-the-month price for each month within such period, unless prices are defined by contractual arrangements, excluding escalations based upon future conditions.

        Under rules of the Securities and Exchange Commission for fiscal years ending prior to December 31, 2009, proved oil and gas reserves are defined as estimated quantities of crude oil, natural gas, and natural gas liquids which geological and engineering data demonstrate with reasonable certainty to be recoverable in future years from known reservoirs under existing economic and operating conditions, i.e., prices and costs as of the date the estimate is made. Prices include consideration of changes in existing prices provided only by contractual arrangements, but not on escalations based upon future conditions.

(A)

Reservoirs are considered proved if economic producibility is supported by either actual production or conclusive formation test. The area of a reservoir considered proved includes (i) that portion delineated by drilling and defined by gas-oil and/or oil-water contacts, if any, and (ii) the immediately adjoining portions not yet drilled, but which can be reasonably judged as economically productive on the basis of available geological and engineering data. In the absence of information on fluid contacts, the lowest known structural occurrence of hydrocarbons controls the lower proved limit of the reservoir.



(B)

Reserves that can be produced economically through application of improved recovery techniques (such as fluid injection) are included in the proved classification when successful testing by a pilot project, or the operation of an installed program in the reservoir, provides support for the engineering analysis on which the project or program was based.



(C)

Estimates of proved reserves do not include the following: (i) Oil that may become available from known reservoirs but is classified separately as indicated additional reserves; (ii) crude oil, natural gas, and natural gas liquids, the recovery of which is subject to reasonable doubt because of uncertainty as to geology, reservoir characteristics, or economic factors; (iii) crude oil, natural gas, and natural gas liquids, that may occur in undrilled prospects; and (iv) crude oil, natural gas, and natural gas liquids that may be recovered from oil shales, coal, gilsonite and other such sources.

        Proved Undeveloped Oil and Gas Reserves—Proved Oil and Gas Reserves that are expected to be recovered from new wells on undrilled acreage, or from existing wells where a relatively major expenditure is required for recompletion.

(A)

Reserves on undrilled acreage are limited to those directly offsetting development spacing areas that are reasonably certain of production when drilled, unless evidence using reliable technology exists that establishes reasonable certainty of economic producibility at greater distances.



(B)

Undrilled locations can be classified as having undeveloped reserves only if a development plan has been adopted indicating that they are scheduled to be drilled within five years, unless the specific circumstances justify a longer time.



(C)

Under no circumstances are estimates for undeveloped reserves to be attributable to any acreage for which an application of fluid injection or other improved recovery technique is contemplated, unless such techniques have been proved effective by actual projects in the same reservoir or an analogous reservoir or by other evidence using reliable technology establishing reasonable certainty.

        PV-10—The present value of estimated future net revenues using a discount rate of 10% per annum.

4

        Recompletion—The process of re-entering an existing wellbore that is either producing or not producing and completing new reservoirs in an attempt to establish or increase existing production.

        Reservoir—A porous and permeable underground formation containing a natural accumulation of producible oil and/or natural gas that is confined by impermeable rock or water barriers and is individual and separate from other reservoirs.

        Standardized Measure of Discounted Future Net Cash Flows—Also referred to herein as "standardized measure." It is the present value of estimated future net revenues computed by discounting estimated future net revenues at a rate of 10% annually.

        The Financial Accounting Standards Board requires disclosure of standardized measure of discounted future net cash flows relating to proved oil and gas reserve quantities per accounting literature for extractive activities—oil and gas, as follows:

        A standardized measure of discounted future net cash flows relating to an enterprise's interests in (a) proved oil and gas reserves and (b) oil and gas subject to purchase under long-term supply, purchase, or similar agreements and contracts in which the enterprise participates in the operation of the properties on which the oil or gas is located or otherwise serves as the producer of those reserves shall be disclosed as of the end of the year. The standardized measure of discounted future net cash flows relating to those two types of interests in reserves may be combined for reporting purposes. The following information shall be disclosed in the aggregate and for each geographic area for which reserve quantities are disclosed:

        a.     Future cash inflows. These shall be computed by applying year-end prices for 2008 and the average of the first-day-of-the-month prices during the 12-month period preceding the end of the year for 2009 and 2010 of oil and gas relating to the enterprise's proved reserves to the year-end quantities of those reserves. Future price changes shall be considered only to the extent provided by contractual arrangements in existence at year-end.

        b.     Future development and production costs. These costs shall be computed by estimating the expenditures to be incurred in developing and producing the proved oil and gas reserves at the end of the year, based on year-end costs and assuming continuation of existing economic conditions. If estimated development expenditures are significant, they shall be presented separately from estimated production costs.

        c.     Future income tax expenses. These expenses shall be computed by applying the appropriate year-end statutory tax rates, with consideration of future tax rates already legislated, to the future pretax net cash flows relating to the enterprise's proved oil and gas reserves, less the tax basis of the properties involved. The future income tax expenses shall give effect to tax deductions, tax credits and allowances relating to the enterprise's proved oil and gas reserves.

        d.     Future net cash flows. These amounts are the result of subtracting future development and production costs and future income tax expenses from future cash inflows.

        e.     Discount. This amount shall be derived from using a discount rate of 10 percent a year to reflect the timing of the future net cash flows relating to proved oil and gas reserves.

        f.      Standardized measure of discounted future net cash flows. This amount is the future net cash flows less the computed discount.

        Working Interest—Also called an operating interest. The right granted to the lessee of a property to explore for and to produce and own oil, gas or other minerals. The working interest owner bears the exploration, development and operating costs on either a cash, penalty or carried basis.

        Workover—Operations on a producing well to restore or increase production.

PART I

Item 1.    Business.

General

        MV Oil Trust, which we refer to as the "trust," was formed in August 2006, by MV Partners, LLC, which we refer to as "MV Partners." Much of the information disclosed herein has been provided to the trust by MV Partners, including information associated with the underlying properties such as production and well counts, major producing areas, customer relationships, competition, marketing and post-production services, and certain information on which reserve data is based.

        The trust is a statutory trust created under the Delaware Statutory Trust Act. The business and affairs of the trust are managed by The Bank of New York Mellon Trust Company, N.A., as trustee. The trust maintains its offices at the office of the trustee, at 919 Congress Avenue, Austin, Texas 78701. The telephone number of the trustee is 1-800-852-1422. In addition, Wilmington Trust Company acts as the Delaware trustee of the trust. The Delaware trustee has only minimal rights and duties as are necessary to satisfy the requirements of the Delaware Statutory Trust Act. The trust does not have any employees and the business and affairs of the trust are managed by The Bank of New York Mellon Trust Company, N.A., as trustee.

        The trustee does not maintain a website for filings by the trust with the Securities and Exchange Commission, which we refer to as the "SEC." Electronic filings by the trust with the SEC are available free of charge through the SEC's website at www.sec.gov and at www.businesswire.com/cnn/mvo.htm.

        As of December 31, 2006, the trust had no assets other than $1,000 cash and had conducted no operations other than in connection with the initial public offering of the units of beneficial interest in the trust, which are referred to herein as the "trust units." On January 24, 2007, MV Partners and the trust completed the initial public offering of trust units. In connection with the completion of the initial public offering of trust units, on January 24, 2007, MV Partners conveyed a term net profits interest to the trust that represents the right to receive 80% of the net proceeds (calculated as described below) from all of MV Partners' interests in oil and natural gas properties as of January 24, 2007, which is referred to herein as the "net profits interest." These properties are located in the Mid-Continent region in the States of Kansas and Colorado. MV Partners' net interests in such properties, after deduction of all royalties and other burdens on production thereon as of January 24, 2007, is referred to herein as the "underlying properties." As of December 31, 2010, the underlying properties produced predominantly oil from approximately 1,000 wells, and the projected reserve life of the underlying properties was in excess of 50 years. Based on the summary prepared by Cawley, Gillespie & Associates, Inc., independent petroleum and geological engineers, which we refer to as "CG&A", of its reserve report as of December 31, 2010 for the trust, which is summarized herein under "—Description of the Underlying Properties—Reserves" and is referred to herein as the "reserve report," the net profits interest would entitle the trust to receive net proceeds from the sale of production of not less than 11.5 MMBoe of proved reserves during the term of the trust, calculated as 80% of the proved reserves attributable to the underlying properties expected to be produced during the term of the trust. Of these reserves, approximately 88% were classified as proved developed producing reserves as of December 31, 2010. Production from the underlying properties for the year ended December 31, 2010 was approximately 98% oil and approximately 2% natural gas and natural gas liquids. The underlying properties are all located in mature fields that are characterized by long production histories and numerous additional development opportunities to help reduce the natural decline in production from the underlying properties.

        The net profits interest will terminate on the later to occur of (1) June 30, 2026, or (2) the time when 14.4 MMBoe have been produced from the underlying properties and sold (which amount is the equivalent of 11.5 MMBoe in respect of the trust's right to receive 80% of the net proceeds from the

6

underlying properties pursuant to the net profits interest). As of December 31, 2010, cumulatively, since inception, the Trust has received payment for approximately 3.3 MMBoe of the trust's 11.5 MMBoe interest. The gross proceeds used to calculate the net profits interest is based on prices realized for oil, natural gas and natural gas liquids attributable to the underlying properties for each calendar quarter during the term of the net profits interest. MV Partners deducts from the gross proceeds all hedge payments made by MV Partners to hedge contract counterparties upon monthly settlements of existing hedge contracts and derivatives to which MV Partners was a party as of January 24, 2007, which is referred to herein as the "hedge contracts." The last hedge contract expired in December 2010. In addition, in connection with the conveyance of the net profits interest, on January 24, 2007, MV Partners also assigned to the trust the right to receive 80% of all amounts payable to MV Partners from hedge contract counterparties upon monthly settlements of the hedge contracts. In calculating the net proceeds used to calculate the net profits interest, MV Partners deducts from the gross proceeds from the underlying properties all lease operating expenses, maintenance expenses and capital expenditures (including the cost of workovers and recompletions, drilling costs and development costs), amounts that may be reserved for future capital expenditures (which reserve amounts may not exceed $1.0 million in the aggregate at any given time), post-production costs and production and property taxes paid by MV Partners.

        Net proceeds payable to the trust depend upon production quantities, sales prices of oil, natural gas and natural gas liquids, and costs to develop and produce the oil, natural gas and natural gas liquids. If at any time costs should exceed gross proceeds, neither the trust nor the trust unitholders would be liable for the excess costs; the trust, however, would not receive any net proceeds until future net proceeds exceed the total amount of those excess costs, plus interest at the prime rate.

        The trust will make quarterly cash distributions of substantially all of its quarterly cash receipts, after deduction of fees and expenses for the administration of the trust, to holders of its trust units during the term of the trust. The trust's first quarterly distribution consisted of an amount in cash paid by MV Partners equal to the amount that would have been payable to the trust had the net profits interest been in effect during the period from July 1, 2006 through December 31, 2006. Furthermore, the cash payment included 80% of all amounts paid to MV Partners from hedge contract counterparties for settlements related to the period from July 1, 2006 through December 31, 2006. Because payments to the trust will be generated by depleting assets and the trust has a finite life with the production from the underlying properties diminishing over time, a portion of each distribution will represent a return of the original investment in the trust units.

        The trust was created to acquire and hold the net profits interest for the benefit of the trust unitholders. The net profits interest is passive in nature and neither the trust nor the trustee has any control over or responsibility for costs relating to the operation of the properties comprising the underlying properties. The business and affairs of the trust are managed by the trustee, and MV Partners and its affiliates have no ability to manage or influence the operations of the trust. The properties comprising the underlying properties for which MV Partners is designated as the operator are currently operated on a contract operator basis by Vess Oil Corporation, which we refer to as "Vess Oil," and Murfin Drilling Company, Inc., which we refer to as "Murfin Drilling," each of which is an affiliate of MV Energy, LLC, which we refer to as "MV Energy," the sole manager of MV Partners. MV Partners does not as a matter of course make public projections as to future sales, earnings or other results relating to the underlying properties.

Description of the Trust Units

        Each trust unit is a unit of the beneficial interest in the trust and is entitled to receive cash distributions from the trust on a pro rata basis. Each trust unitholder has the same rights regarding each of his trust units as every other trust unitholder has regarding his units. The trust units are in book-entry form only and are not represented by certificates. The trust had 11,500,000 trust units outstanding as of March 11, 2011.

Distributions and Income Computations

        Each quarter, the trustee will determine the amount of funds available for distribution to the trust unitholders. Available funds are the excess cash, if any, received by the trust from the net profits interest, payments from the hedge contracts and other sources (such as interest earned on any amounts reserved by the trustee) in that quarter, over the trust's expenses for that quarter. Available funds will be reduced by any cash the trustee decides to hold as a reserve against future expenses. It is expected that quarterly cash distributions during the term of the trust will be made by the trustee on or before the 25^th day of the month following the end of each quarter to the trust unitholders of record on the 15^th day of the month following the end of each quarter (or the next succeeding business day).

        Unless otherwise advised by counsel or the Internal Revenue Service, which we refer to herein as the "IRS," the trustee will treat the income and expenses of the trust for each quarter as belonging to the trust unitholders of record on the quarterly record date. For federal income tax purposes, trust unitholders must take into account items of income, gain, loss, deduction and credit consistent with their methods of accounting and without regard to the taxable year or accounting method employed by the trust and without regard to the quarter the trust makes distributions related to those items to the trust unitholders. Variances between taxable income and cash distributions may occur. For example, the trustee could establish a reserve in one quarter using funds that would be included in income in the quarter in which the reserve is created but may not result in a tax deduction or a distribution until a later quarter or possibly in a later taxable year. Similarly, the trustee could also make a payment in one quarter that would be amortized for income tax purposes over several quarters. See "—Federal Income Tax Matters."

        As publicly reported, on July 22, 2008, SemCrude, L.P., which we refer to as "SemCrude," and certain of its affiliates, including Eaglwing, L.P., which we refer to as "Eaglwing," filed voluntarily petitions for reorganization under Chapter 11 of the United States Bankruptcy Code. SemCrude was a counterparty to some of MV Partners' fixed price swap contracts. Eaglwing purchased substantially all of the crude oil production of the underlying properties for the month of June 2008 and for the first 18 days of July 2008, after which date further sales to Eaglwing were terminated. Payment for approximately $9.5 million of the June sales to Eaglwing was due by July 20, 2008, and payment for approximately $5.9 million of the July sales to Eaglwing was due by August 20, 2008. The specified dollar amounts are associated with all production from the underlying properties, and not just the 80% portion attributable to the net profits interest held by the trust.

        On October 28, 2009, a bankruptcy judge confirmed the SemGroup Fourth Amended Plan of Reorganization, which we refer to as the "Plan." Under the Plan, producers are to recover a portion of their undisputed allowed claims against SemCrude and certain of its affiliates, including Eaglwing, which we refer to collectively as, the "SemGroup." The amount recoverable by each producer depends on various factors, including the dates of sale to the SemGroup. Pursuant to the Plan, producers that sold oil and gas to the SemGroup on and between July 2, 2008 and July 22, 2008, which we refer to as the "July Sales," are to receive 100% of their undisputed allowed claims and producers that sold oil and gas to the SemGroup between June 1, 2008 and July 1, 2008 are to receive a proportionate allocation of the remaining cash for the allowed secured producer claims.

8

        On December 1, 2009, the SemGroup filed with the bankruptcy court a verification that the conditions had been met for the Plan to become effective and that the settlement with producers proposed in the Plan would be funded, and in connection therewith, emerged from bankruptcy. In April 2010, MV Partners received payment of $5,627,233, representing 100% of its claims for the July Sales. Because MV Partners received this payment in April 2010, such amount was included in the calculation of net proceeds attributable to the net profits interest of the trust for the second quarter of 2010 and is reflected in the trust's third quarter 2010 financial statements.

        In September 2010, Vess Oil and Murfin Drilling, which are the operators of the underlying properties of MV Partners, received funds for the collection of the sale of oil volumes to SemCrude and Eaglwing for the period between June 1, 2008 and July 1, 2008. The collected funds represent the payout on proofs of claims filed by Vess Oil and Murfin Drilling on a lease by lease basis on their own behalf and on behalf of various working interest owners (inclusive of MV Partners' interests), overriding royalty owners and royalty owners. The funds were assessed and allocated among the various working interest owners, overriding royalty owners and royalty owners, with Vess Oil and Murfin Drilling determining that MV Partners' portion was $1,274,477. During the fourth quarter of 2010, MV Partners received such allocated portion and such dollar amount was included in the calculation of the net profits interests for the fourth quarter of 2010. The trust received 80% of such funds in connection with the quarterly distribution for the period ended December 31, 2010, in the first quarter of 2011.

        From July 18, 2008 until July 31, 2008, only minor amounts of crude oil production from the underlying properties were sold. On July 31, 2008, Vess Oil and Murfin Drilling recommenced general sales of production from the underlying properties to several purchasers other than Eaglwing, including an affiliated purchaser, under short-term arrangements using market sensitive pricing. As of August 7, 2008, field operations at the underlying properties returned to substantially normal operations, although it took until mid-August before the marketing of crude oil production normalized to the sales process and volumes that existed prior to July 18, 2008.

        As discussed above, Eaglwing purchased substantially all of the crude oil production of the underlying properties for the month of June 2008 and for the first 18 days of July 2008 and subsequently filed for bankruptcy. Because of Eaglwing's bankruptcy and failure to pay for such production, the trust did not make a fourth quarterly distribution in October 2008 and the first quarterly distribution in January 2009 was substantially impacted. See "Trustee's Discussion and Analysis of Financial Condition and Results of Operations."

Periodic Reports

        The trustee files all required trust federal and state income tax and information returns. The trustee prepares and provides the tax information that trust unitholders need to correctly report their share of the income and deductions of the trust. The trustee also causes to be prepared and filed reports required to be filed under the Exchange Act and by the rules of any securities exchange or quotation system on which the trust units are listed or admitted to trading, and also causes the trust to comply with the provisions of the Sarbanes-Oxley Act, including but not limited to, by establishing, evaluating and maintaining a system of internal controls over financial reporting in compliance with the requirements of Section 404 thereof.

        Each trust unitholder and his representatives may examine, for any proper purpose, during reasonable business hours, the records of the trust and the trustee.

Liability of Trust Unitholders

        Under the Delaware Statutory Trust Act, trust unitholders are entitled to the same limitation of personal liability extended to stockholders of private corporations for profit under the General Corporation Law of the State of Delaware. No assurance can be given, however, that the courts in jurisdictions outside of Delaware will give effect to such limitation.

Voting Rights of Trust Unitholders

        The trustee or trust unitholders owning at least 10% of the outstanding trust units may call meetings of trust unitholders. The trust is responsible for all costs associated with calling a meeting of trust unitholders unless such meeting is called by the trust unitholders, in which case the trust unitholders are responsible for all costs associated with calling such meeting of trust unitholders. Meetings must be held in such location as is designated by the trustee in the notice of such meeting. The trustee must send written notice of the time and place of the meeting and the matters to be acted upon to all of the trust unitholders at least 20 days and not more than 60 days before the meeting. Trust unitholders representing a majority of trust units outstanding must be present or represented to have a quorum. Each trust unitholder is entitled to one vote for each trust unit owned.

        Unless otherwise required by the trust agreement, a matter may be approved or disapproved by the vote of a majority of the trust units held by the trust unitholders at a meeting where there is a quorum. This is true even if a majority of the total trust units did not approve it. The affirmative vote of the holders of a majority of the outstanding trust units is required to:

•

dissolve the trust;



•

remove the trustee or the Delaware trustee;



•

amend the trust agreement (except with respect to certain matters that do not adversely affect the rights of trust unitholders in any material respect);



•

merge or consolidate the trust with or into another entity; or



•

approve the sale of all or any material part of the assets of the trust.

        In addition, certain amendments to the trust agreement may be made by the trustee without approval of the trust unitholders. The trustee must consent before all or any part of the trust assets can be sold except in connection with the dissolution of the trust or limited sales directed by MV Partners in conjunction with its sale of underlying properties.

Duration of the Trust; Sale of the Net Profits Interest

        The trust will remain in existence until the later to occur of (1) June 30, 2026, or (2) the time when 14.4 MMBoe have been produced from the underlying properties and sold (which amount is the equivalent of 11.5 MMBoe in respect of the trust's right to receive 80% of the net proceeds from the underlying properties pursuant to the net profits interest). The trust will dissolve prior to its termination if:

•

the trust sells the net profits interest;



•

annual gross proceeds attributable to the net profits interest are less than $1 million for each of two consecutive years;



•

the holders of a majority of the outstanding trust units vote in favor of dissolution; or



•

there is a judicial dissolution of the trust.

        The trustee would then sell all of the trust's assets, either by private sale or public auction, and distribute the net proceeds of the sale to the trust unitholders.

Computation of Net Proceeds

        The provisions of the conveyance governing the computation of the net proceeds are detailed and extensive. The following information summarizes the material information contained in the conveyance related to the computation of the net proceeds. For more detailed provisions concerning the net profits interest, you should read the conveyance, which is referenced as an exhibit to this Form 10-K.

Net Profits Interest

        The term net profits interest was conveyed to the trust by MV Partners on January 24, 2007 by means of a conveyance instrument that has been recorded in the appropriate real property records in each county in Kansas and Colorado where the oil and natural gas properties to which the underlying properties relate are located. The net profits interest burdens the net interests owned by MV Partners in the properties comprising the underlying properties in existence as of January 24, 2007.

        The amounts paid to the trust for the net profits interest are based on the definitions of "gross proceeds" and "net proceeds" contained in the conveyance and described below. Under the conveyance, net proceeds are computed quarterly, and 80% of the aggregate net proceeds attributable to a computation period will be paid to the trust on or before the 25^th day of the month following the computation period. MV Partners will not pay to the trust any interest on the net proceeds held by MV Partners prior to payment to the trust. The trustee will make distributions to trust unitholders quarterly, if sufficient funds are available. See "—Description of the Trust Units—Distributions and Income Computations."

        "Gross proceeds" means:

•

the aggregate amount received by MV Partners from sales of oil, natural gas and natural gas liquids produced from the underlying properties (other than amounts received for certain future non-consent operations), less



•

the aggregate amounts paid by MV Partners upon settlement of the hedge contracts on a quarterly basis, as specified in the hedge contracts.

        Gross proceeds does not include consideration for the transfer or sale of any underlying property by MV Partners or any subsequent owner to any new owner unless the net profits interest is released (as is permitted in certain circumstances). Gross proceeds also does not include any amount for oil, natural gas or natural gas liquids lost in production or marketing or used by the owner of the underlying properties in drilling, production and plant operations. Gross proceeds includes payments for future production if they are not subject to repayment in the event of insufficient subsequent production.

        "Net proceeds" means gross proceeds less the following:

•

all payments to mineral or landowners, such as royalties or other burdens against production, delay rentals, shut-in oil and natural gas payments, minimum royalty or other payments for drilling or deferring drilling;



•

any taxes paid by the owner of an underlying property to the extent not deducted in calculating gross proceeds, including estimated and accrued general property (ad valorem), production, severance, sales, gathering, excise and other taxes;



•

any extraordinary taxes or windfall profits taxes that may be assessed in the future that are based on profits realized or prices received for production from the underlying properties;



•

costs paid by an owner of a property comprising the underlying properties under any joint operating agreement;

11

•

all other costs and expenses, capital costs and liabilities of exploring for, drilling, recompleting, workovers, operating and producing oil, natural gas and natural gas liquids, including allocated expenses such as labor, vehicle and travel costs and materials and any plugging and abandonment liabilities (net of any capital costs for which a reserve had already been made to the extent such capital costs are incurred during the computation period) other than costs and expenses for certain future non-consent operations;



•

costs or charges associated with gathering, treating and processing oil, natural gas and natural gas liquids;



•

any overhead charge incurred pursuant to any operating agreement relating to an underlying property, including the overhead fee payable by MV Partners to Vess Oil and Murfin Drilling as described below;



•

costs paid to counterparties under the hedge contracts or to the persons that provide credit to maintain any hedge contracts, excluding any hedge settlement amounts;



•

amounts previously included in gross proceeds but subsequently paid as a refund, interest or penalty;



•

costs and expenses for renewals or extensions of leases; and



•

at the option of MV Partners (or any subsequent owner of the underlying properties), amounts reserved for approved capital expenditure projects, including well drilling, recompletion and workover costs, which amounts will at no time exceed $1.0 million in the aggregate, and will be subject to the limitations described below.

        During each twelve-month period beginning on the later to occur of (1) June 30, 2023 and (2) the time when 13.2 MMBoe have been produced from the underlying properties and sold (which is the equivalent of 10.6 MMBoe in respect of the net profits interest), which we refer to, in either case, as the "Capital Expenditure Limitation Date", the sum of the capital expenditures and amounts reserved for approved capital expenditure projects for such twelve- month period may not exceed the Average Annual Capital Expenditure Amount. The "Average Annual Capital Expenditure Amount" means the quotient of (x) the sum of the capital expenditures and amounts reserved for approved capital expenditure projects with respect to the three twelve-month periods ending on the Capital Expenditure Limitation Date, divided by (y) three. Commencing on the Capital Expenditure Limitation Date, and each anniversary of the Capital Expenditure Limitation Date thereafter, the Average Annual Capital Expenditure Amount will be increased by 2.5% to account for expected increased costs due to inflation.

        As is customary in the oil and natural gas industry, MV Partners pays an overhead fee to Vess Oil and Murfin Drilling to operate the underlying properties on behalf of MV Partners. The operating activities include various engineering, accounting and administrative functions. The fee is based on a monthly charge per active operated well, which totaled $2.8 million in 2010, $2.7 million in 2009 and $2.5 million in 2008 for all of the properties comprising the underlying properties for which MV Partners was designated as the operator. The fee is adjusted annually and will increase or decrease each year based on changes in the year-end index of average weekly earnings of crude petroleum and natural gas workers.

        In the event that the net proceeds for any computation period is a negative amount, the trust will receive no payment for that period, and any such negative amount plus accrued interest at the prime rate will be deducted from gross proceeds in the following computation period for purposes of determining the net proceeds for that following computation period.

        Gross proceeds and net proceeds are calculated on a cash receipts and cash disbursements basis.

12

Hedge Contracts

        Prior to the entry of the conveyance, MV Partners had entered into certain hedge contracts related to the oil production from the underlying properties through the year ended December 31, 2010. MV Partners has not entered into hedge contracts relating to oil volumes expected to be produced after December 31, 2010, and the terms of the conveyance of the net profits interest prohibit MV Partners from entering into new hedging arrangements for the benefit of the trust.

Additional Provisions

        If a controversy arises as to the sales price of any production, then for purposes of determining gross proceeds:

•

amounts withheld or placed in escrow by a purchaser are not considered to be received by the owner of the underlying property until actually collected;



•

amounts received by the owner of the underlying property and promptly deposited with a nonaffiliated escrow agent will not be considered to have been received until disbursed to it by the escrow agent; and



•

amounts received by the owner of the underlying property and not deposited with an escrow agent will be considered to have been received.

        The trustee is not obligated to return any cash received from the net profits interest. Any overpayments made to the trust by MV Partners due to adjustments to prior calculations of net proceeds or otherwise will reduce future amounts payable to the trust until MV Partners recovers the overpayments plus interest at the prime rate.

        The conveyance generally permits MV Partners to transfer without the consent or approval of the trust unitholders all or any part of its interest in the underlying properties, subject to the net profits interest. The trust unitholders are not entitled to any proceeds of a sale or transfer of MV Partners' interest unless the trust is required to sell the net profits interest as to such interest. Following a sale or transfer, the underlying properties will continue to be subject to the net profits interest, and the net proceeds attributable to the transferred property will be calculated as part of the computation of net proceeds described in this Form 10-K.

        In addition, MV Partners may, without the consent of the trust unitholders, require the trust to release the net profits interest associated with any lease that accounts for less than or equal to 0.25% of the total production from the underlying properties in the prior 12 months and provided that the net profits interest covered by such releases cannot exceed, during any 12-month period, an aggregate fair market value to the trust of $500,000. These releases will be made only in connection with a sale by MV Partners of the relevant underlying properties and are conditioned upon the trust receiving an amount equal to the fair value to the trust of such net profits interest. Any net sales proceeds paid to the trust are distributable to trust unitholders for the quarter in which they are received.

        As the designated operator of a property comprising the underlying properties, MV Partners may enter into farm-out, operating, participation and other similar agreements to develop the property. MV Partners may enter into any of these agreements without the consent or approval of the trustee or any trust unitholder.

        MV Partners and any transferee of an underlying property will have the right to abandon any well or property if it reasonably believes the well or property ceases to produce or is not capable of producing in commercially paying quantities. In making such decisions, MV Partners or any transferee of an underlying property is required under the applicable conveyance to act as a reasonably prudent operator in the State of Kansas under the same or similar circumstances would act if it were acting with respect to its own properties, disregarding the existence of the net profits interest as a burden on

13

such property. Upon termination of the lease, the portion of the net profits interest relating to the abandoned property will be extinguished.

        MV Partners must maintain books and records sufficient to determine the amounts payable for the net profits interest to the trust. Quarterly and annually, MV Partners must deliver to the trustee a statement of the computation of the net proceeds for each computation period. The trustee has the right to inspect and copy the books and records maintained by MV Partners during normal business hours and upon reasonable notice.

Federal Income Tax Matters

        The following is a summary of certain U.S. federal income tax matters that may be relevant to trust unitholders. This summary is based upon current provisions of the Internal Revenue Code of 1986, as amended, which we refer to as the "Code," existing and proposed Treasury regulations thereunder and current administrative rulings and court decisions, all of which are subject to changes that may or may not be retroactively applied. No attempt has been made in the following summary to comment on all U.S. federal income tax matters affecting the trust or the trust unitholders.

        The summary is limited to trust unitholders who are individual citizens or residents of the United States. Accordingly, the following summary has limited application to domestic corporations and persons subject to specialized federal income tax treatment such as, without limitation, tax-exempt organizations, regulated investment companies, insurance companies and foreign persons or entities. Each trust unitholder should consult his own tax advisor with respect to his particular circumstances.

        Tax counsel to the trust advised the trust at the time of formation that, for federal income tax purposes, in its opinion the trust will be treated as a grantor trust and not as an unincorporated business entity. No ruling has been or will be requested from the IRS with respect to the federal income tax treatment of the trust, including as to the status of the trust as a grantor trust for such purposes. Thus, no assurance can be provided that the tax treatment of the trust would be sustained by a court if contested by the IRS or another tax authority. The remainder of the discussion below is based on tax counsel's opinion, at the time of formation, that the trust will be classified as a grantor trust for federal income tax purposes. As a grantor trust, the trust will not be subject to federal income tax at the trust level. Rather, each trust unitholder will be considered for federal income tax purposes to own its proportionate share of the trust's assets directly as though no trust were in existence. The income of the trust is deemed to be received or accrued by the trust unitholder at the time such income is received or accrued by the trust, rather than when distributed by the trust. Each trust unitholder will be subject to tax on its proportionate share of the income and gain attributable to the assets of the trust and will be entitled to claim its proportionate share of the deductions and expenses attributable to the assets of the trust, subject to applicable limitations, in accordance with the trust unitholder's tax method of accounting and without regard to the taxable year or accounting method employed by the trust.

        The trust will allocate items of income, gain, loss, deductions and credits to trust unitholders based on record ownership at each quarterly record date. It is possible that the IRS or another tax authority could disagree with this allocation method and could assert that income and deductions of the trust should be determined and allocated on a daily, prorated or other basis, which could require adjustments to the tax returns of the trust unitholders affected by the issue and result in an increase in the administrative expense of the trust in subsequent periods.

        Tax counsel to the trust also advised the trust at the time of formation that, for federal income tax purposes, based upon representations made by MV Partners regarding the expected economic life of the underlying properties and the expected duration of the net profits interest, in its opinion the net profits interest should be treated as a "production payment" under Section 636 of the Code or otherwise as a debt instrument. On the basis of that advice, the trust will treat the net profits interest

14

as indebtedness subject to Treasury regulations applicable to contingent payment debt instruments, and by purchasing trust units, a trust unitholder will agree to be bound by the trust's application of those regulations, including the trust's determination of the rate at which interest will be deemed to accrue on the net profits interest. No assurance can be given that the IRS or another taxing authority will not assert that the net profits interest should be treated differently. Any such different treatment could affect the amount, timing and character of income, gain or loss in respect of an investment in trust units and could require a trust unitholder to accrue income at a rate different than that determined by the trust.

        Tax counsel to the trust advised the trust at the time of formation that, for federal income tax purposes, in its opinion the net profits interest should not be integrated with the hedge contracts. Although not definitively addressed by existing authorities, the federal income tax treatment of the net profits interest may be affected by the right to receive payments under the hedge contracts. Specifically, the right to receive payments on the hedge contracts could be integrated with the net profits interest and deemed to be a source other than production for repayment of the net profits interest, which characterization could adversely affect the treatment of the net profits interest as a production payment, and thus a debt instrument, for federal income tax purposes.

Widely Held Fixed Investment Trust Reporting Information

        The trustee assumes that some trust units are held by a middleman, as such term is broadly defined in Treasury regulations (and includes custodians, nominees, certain joint owners, and brokers holding an interest for a custodian in street name). Therefore, the trustee considers the trust to be a non-mortgage widely held fixed investment trust ("WHFIT") for U.S. federal income tax purposes. The Bank of New York Mellon Trust Company, N.A., 919 Congress Avenue, Austin, Texas 78701, telephone number 1-800-852-1422, is the representative of the trust that will provide tax information in accordance with applicable Treasury regulations governing the information reporting requirements of the trust as a WHFIT.

Available Trust Tax Information

        In compliance with the reporting requirements for WHFITs and the dissemination of trust tax reporting information, the trustee provides a generic tax information reporting booklet that is intended to be used only to assist unitholders in the preparation of their 2010 federal and state income tax returns. The projected payment schedule for the net profits interest is included with the tax information booklet. This tax information booklet can be obtained at www.businesswire.com/cnn/mvo.htm.

Description of the Underlying Properties

        The underlying properties consist of MV Partners' net interests in all of its oil and natural gas properties as of January 24, 2007, which properties are located in the Mid-Continent region in the States of Kansas and Colorado. Affiliates of MV Partners are currently the operators or contract operators of substantially all of the properties comprising the underlying properties.

        MV Partners' interests in the properties comprising the underlying properties require MV Partners to bear its proportionate share, along with the other working interest owners, of the costs of development and operation of such properties. The properties comprising the underlying properties are burdened by non-working interests owned by third parties, consisting primarily of royalty interests retained by the owners of the land subject to the working interests. These landowners' royalty interests typically entitle the landowner to receive 12.5% of the revenue derived from oil and natural gas production resulting from wells drilled on the landowner's land, without any deduction for drilling costs or other costs related to production of oil and natural gas. A working interest percentage represents a working interest owner's proportionate ownership interest in a property in relation to all other working

15

interest owners in that property, whereas a net revenue interest percentage is a working interest owner's percentage of production after reducing such percentage by the percentage of burdens on such production such as royalties and overriding royalties.

        Based on the reserve report, the net profits interest would entitle the trust to receive net proceeds from the sale of production of not less than 11.5 MMBoe of proved reserves attributable to the underlying properties expected to be produced during the term of the net profits interest, calculated as 80% of the proved reserves attributable to the underlying properties expected to be produced during the term of the net profits interest. The reserves attributable to the underlying properties include all reserves expected to be economically produced during the life of the properties, whereas the trust is entitled to only receive 80% of the net proceeds from the sale of production of oil, natural gas and natural gas liquids attributable to the underlying properties during the term of the net profits interest.

        The Mid-Continent region is a mature producing region with well-known geologic characteristics. Most of the production from the underlying properties consists of desirable crude oil of a quality level between sweet and sour with 33 to 34 gravity averages. Most of the producing wells to which the underlying properties relate are relatively shallow, ranging from 600 to 4,500 feet, and many are completed to multiple producing zones. In general, the producing wells to which the underlying properties relate have stable production profiles and their production is generally long-lived, often with total projected economic lives in excess of 50 years.

Reserves

        The engineering departments of each of Vess Oil and Murfin Drilling, who together manage MV Partners and operate the underlying properties, maintain oversight and compliance responsibility for the internal reserve estimate process and, in accordance with internal policies and procedures, provide appropriate data to independent third party engineers for the annual estimation of year-end reserves. These engineering departments accumulate historical production data for the underlying properties, calculate historical lease operating expenses and differentials, update working interests and net revenue interests, and obtain logs, 3-D seismic and other geological and geophysical information. This data is forwarded to CG&A, thereby allowing CG&A to prepare estimated proved reserves in their entirety based on such data.

        Estimates of the proved oil and gas reserves attributable to the trust as of December 31, 2007, 2008, 2009 and 2010 are based on reports of CG&A. CG&A has been in business since 1961 and serves many organizations and individuals in the petroleum industry, including owners and operators of oil and gas properties, exploration groups, planners, and professionals in investment and finance. One of the principal businesses of CG&A is providing detailed assessment of producing reservoirs. CG&A is an independent firm of petroleum engineers, geologists, geophysicists and petrophysicists and does not own an interest in the underlying properties and is not employed on a contingent basis. Mr. W. Todd Brooker, Vice President, is the technical person at CG&A who is primarily responsible for overseeing CG&A's preparation of the reserve estimates. Mr. Brooker is a graduate of the University of Texas at Austin with a Bachelor of Science degree in Petroleum Engineering and has 19 years of experience in petroleum engineering. He is a licensed professional engineer in the State of Texas (License #83462).

        In December 2008, the SEC released the final rule for "Modernization of Oil and Gas Reporting." This rule requires disclosure of oil and gas proved reserves by significant geographic area, using the 12-month average beginning-of-month price for the year, rather than year-end prices, and allows the use of reliable technologies to estimate proved oil and gas reserves, if those technologies have been demonstrated to result in reliable conclusions about reserves volumes. In addition, companies are required to report on the independence and qualifications of its reserves preparer or auditor, and file reports when a third party is relied upon to prepare reserves estimates or conduct a reserves audit. Reserve and related information for 2009 and 2010 is presented consistent with the requirements of this rule. This rule does not allow prior-year reserve information to be restated, so all information related to periods prior to 2009 is presented consistent with prior SEC rules for the estimation of proved reserves.

16

        The discounted estimated future net revenues presented below were prepared using assumptions required by the SEC. Except to the extent otherwise described below, these assumptions include the use of prices for oil, natural gas and natural gas liquids for the reserve report as of December 31, 2010, of $72.33 per Bbl of oil, $3.97 per Mcf of natural gas and $42.41 per Bbl of natural gas liquids, net of pricing differentials, as well as costs for estimated future development and production expenditures to produce the proved reserves as of December 31, 2010. Because oil, natural gas and natural gas liquid prices are influenced by many factors, use of average prices for the reserve report as of December 31, 2010, as required by the SEC, may not be the most accurate basis for estimating future revenues of reserve data. Future net cash flows are discounted at an annual rate of 10%. There is no provision for federal or state income taxes with respect to the future net cash flows attributable to the underlying properties because future net revenues are not subject to taxation at the trust level.

        Proved Reserves of MV Oil Trust.    The following table sets forth, as of December 31, 2010, estimated proved reserves attributable to the trust derived from the reserve report. A summary of the reserve report is included below.

        Information concerning historical changes in net proved reserves attributable to the trust, and the calculation of the standardized measure of discounted future net revenues related thereto, is contained in Note K to the financial statements of the trust included in this Form 10-K. MV Partners has not filed reserve estimates covering the underlying properties with any other federal authority or agency.

17

        The following table summarizes the changes in estimated proved reserves of the trust for the periods indicated.

        The reserves above represent the trust's 80% net profits interest in the underlying properties for the remainder of the term of the trust.

        The following table sets forth the estimates of total proved reserves and forecasts of economics attributable to the underlying properties as of December 31, 2010 for the remainder of the term of the trust, as presented in the summary prepared by CG&A of its reserve report as of December 31, 2010 for the trust. The estimates of proved reserves have not been filed with or included in reports to any

18

federal authority or agency. The discounted cash flow value shown in the table is not intended to represent the current market value of the trust's estimated oil and natural gas reserves.

        The net profits interest entitles the trust to receive 80% of the net proceeds attributable to MV Partners' interest from the sale of production from the underlying properties. The net profits interest will terminate on the later to occur of (1) June 30, 2026, or (2) the time when 14.4 MMBoe have been produced from the underlying properties and sold, and the trust will soon thereafter wind up its affairs and terminate. For the reserve report, CG&A estimated that the trust would terminate June 30, 2026 based on the calculation that 14.4 MMBoe would have been produced from the underlying properties and sold (which amount is the equivalent of 11.5 MMBoe in respect of the trust's right to receive 80% of the net proceeds from the underlying properties pursuant to the net profits interest) prior to this date.

        Oil and gas prices were adjusted to a WTI Cushing oil price of $79.43 per Bbl and a Henry Hub natural gas price of $4.37 per MMbtu. As specified by the SEC, these prices are 12-month averages based upon the price on the first day of each month during 2010. The price adjustments were based on oil price differentials forecast at -$7.10 per Bbl for all properties. Oil price differentials were not escalated. Gas and NGL price differentials were forecast on a per property basis as provided by MV Partners and were also not escalated. Price differentials include adjustments for transportation and basis differential. Gas prices were further adjusted with a heating value (Btu content) applied on a per-property basis. Operating expenses, workover expenses, COPAS overhead charges and investments were forecast on a per property basis as furnished by MV Partners. Expenses and investments were held constant in accordance with SEC rules and guidelines. Severance tax rates were applied at normal state percentages of oil and gas revenue, except for those Kansas producing properties that are severance tax exempt. Ad valorem taxes of 3.0% of total revenue were applied to each property as provided by MV Partners. Oil and gas conservation tax rates were applied to all Kansas properties at the applicable rates.

19

        The estimates of proved oil and natural gas reserves attributable to the underlying properties are based on estimates prepared by CG&A. Rules and guidelines established by the SEC regarding the present value of future net revenues were used to prepare these reserve estimates. Oil and natural gas reserve engineering is a subjective process of estimating underground accumulations of oil and natural gas that cannot be measured in an exact way, and estimates of other engineers might differ materially from those included in the report. The accuracy of any reserve estimate is a function of the quality of available data and engineering, and estimates may justify revisions based on the results of drilling, testing, and production activities. Accordingly, reserve estimates are inherently imprecise and should not be construed as representing the actual quantities of future production or cash flows to be realized from oil and natural gas properties or the fair market value of such properties.

Producing Acreage and Well Counts

        For the following data, "gross" refers to the total wells or acres in which MV Partners owns a working interest and "net" refers to gross wells or acres multiplied by the percentage working interest owned by MV Partners. Although many of MV Partners' wells produce both oil and natural gas, a well is categorized as an oil well or a natural gas well based upon the ratio of oil to natural gas production.

        The underlying properties are interests in developed properties located in oil and natural gas producing regions of Kansas and eastern Colorado. The following is a summary of the approximate acreage of the underlying properties at December 31, 2010.

        The following is a summary of the producing wells on the underlying properties as of December 31, 2010:
