NOTES TO CONDENSED FINANCIAL STATEMENTS

(Unaudited)



|1. | Accounting Policies
|-- | -------------------

Reference is hereby made to the Registrants Annual Report on Form 10, which contains a summary of significant accounting policies followed by the Partnership in the preparation of its financial statements. These policies are also
followed in preparing the quarterly report included herein.

In the opinion of management, the accompanying unaudited financial
statements contain all adjustments of a normal recurring nature necessary to present fairly our financial position, results of operations, cash flows and partners capital for the periods presented. The results of operations for the interim
periods are not necessarily indicative of the final results expected for the full year. We have evaluated the impact on these condensed financial statements of all subsequent events through November 16, 2009, the date the financial statements
were issued.



|2. | Accounting for Oil and Gas Producing Activities
|-- | -----------------------------------------------

Mewbourne Energy Partners 08-A, L.P., (the Registrant or the Partnership), a Delaware limited partnership engaged primarily in oil and gas development and production in Texas, Oklahoma, and
New Mexico, was organized on March 7, 2008. The offering of limited and general partner interests began May 1, 2008 as a part of a private placement pursuant to Section 4(2) of the Securities Act of 1933 and Regulation D promulgated
thereunder, and concluded August 4, 2008, with total investor contributions of $73,000,000 originally being sold to accredited investors of which $68,105,000 were sold to accredited investors as general partner interests and $4,895,000 were
sold to accredited investors as limited partner interests. The managing general partner, Mewbourne Development Corporation (MD), has no significant equity interest in the Partnership.

The Partnership follows the full-cost method of accounting for its oil and gas activities. Under the full-cost method, all productive and
non-productive costs incurred in the acquisition, exploration and development of oil and gas properties are capitalized. Depreciation, depletion and amortization of oil and gas properties subject to amortization is computed on the
units-of-production method based on the proved reserves underlying the oil and gas properties. At September 30, 2009, approximately $6.4 million of capitalized costs were excluded from amortization. Proceeds from the sale or other disposition
of properties are credited to the full cost pool. Gains and losses on the sale or other disposition of properties are not recognized unless such adjustments would significantly alter the relationship between capitalized costs and the proved oil and
gas reserves. Capitalized costs are subject to a quarterly ceiling test that limits such costs to the aggregate of the present value of future net cash flows of proved reserves and the lower of cost or fair value of unproved properties. There was a
cost ceiling write-down of $12,496,218 at March 31, 2009 but none at June 30, 2009 or September 30, 2009. There were no cost ceiling write-downs during the period from March 7, 2008 (date of inception) through September 30,
2008.

|3. | Asset Retirement Obligations
|-- | ----------------------------

The Partnership has recognized an estimated liability for future plugging and abandonment costs. The estimated liability is based on historical experience and estimated well life. The liability is discounted using the credit-adjusted
risk-free rate. Revisions to the liability could occur due to changes in well ownership interests, well plugging and abandonment costs or well useful lives, or if federal or state regulators enact new well restoration requirements. The Partnership
recognizes accretion expense in connection with the discounted liability over the remaining life of the well.

A reconciliation of the
Partnerships liability for well plugging and abandonment costs for the nine months ended September 30, 2009 and the period from March 7, 2008 (date of inception) through December 31, 2008 is as follows:

|4. | Related Party Transactions
|-- | --------------------------

In accordance with the laws of the State of Delaware, Mewbourne Development Corporation (MD), a Delaware Corporation, has been appointed as the Partnerships managing general partner. MD has no significant equity interest
in the Partnership. Mewbourne Oil Company (MOC) is operator of oil and gas properties owned by the Partnership. Mewbourne Holdings, Inc. is the parent of both MD and MOC. Substantially all transactions are with MD and MOC.

In the ordinary course of business, MOC will incur certain costs that will be passed on to owners of the well for which the costs were incurred. The
Partnership will receive their portion of these costs based upon their ownership in each well incurring the costs. These costs are referred to as operator charges and are standard and customary in the oil and gas industry. Operator charges include
recovery of gas marketing costs, fixed rate overhead, supervision, pumping, and equipment furnished by the operator. Services and operator charges are billed in accordance with the program and partnership agreements.

In consideration for services rendered by MD in managing the business of the Partnership, the Partnership during each of the initial three years of
the Partnership will pay to MD a management fee in the amount equal to .7% of the subscriptions by the investor partners to the Partnership. The Partnership will include the management fee as part of the full cost pool pursuant to 4-10(c)(2) of
Regulation S-X.

In general, during any particular calendar year the total amount of administrative expenses allocated to the
Partnership by MOC shall not exceed the greater of (a) 3.5% of the Partnerships gross revenue from the sale of oil and natural gas production during each year (calculated without any deduction for operating costs or other costs and
expenses) or (b) the sum of $50,000 plus .25% of the capital contributions of limited and general partners.

|5. | Legal Proceedings
|-- | -----------------

MOC
filed suit on March 9, 2009 in the U.S. District Court, Tyler Division, seeking a judicial declaration of its rights under a drilling contract with defendant Zenith Drilling Corporation. MOC contends that the contract releases it from any claim
for damage to Zeniths drilling rig from a fire that occurred on January 9, 2009 during drilling operations on the Leslie Webb No. 1893 well in which the Partnership owns an interest. Zenith filed its Answer and Counterclaim on
April 2, 2009, and later amended its counterclaim disputing MOCs interpretation of the contract, and claiming that MOC is liable to pay Zenith for damage to its drilling rig.

MOC is defending against Zeniths claims vigorously. In October, 2009, MOC filed its Motion for Summary Judgment. Zeniths response has not been received. Currently it remains
premature to predict an outcome of the case. In any event, we believe that the eventual outcome of the case will not have a material impact on the Partnerships operations or financial position.

Item 2.    Managements Discussion and Analysis of Financial
Condition and Results of Operations

Liquidity and Capital Resources

Mewbourne Energy Partners 08-A, L.P. (the Partnership) was formed March 7, 2008. The offering of limited and general partnership interests began May 1, 2008 and concluded
August 4, 2008, with total investor contributions of $73,000,000.

The Registrant owns fractional working interests in
developmental oil and gas prospects, which has resulted in participation in the drilling of oil and gas wells. At September 30, 2009, the Registrant owned working interests in 114 producing wells.

Future capital requirements and operations will be conducted with available funds generated from oil and gas activities. No bank borrowing is
anticipated. The Partnership had net working capital of $7,530,089 at September 30, 2009.

During the nine months ended
September 30, 2009, the Partnership made cash distributions to the investor partners in the amount of $8,695,000. The Partnership expects that cash distributions will continue during 2009 as additional oil and gas revenues are sufficient to
produce cash flows from operations.

The sale of crude oil and natural gas produced by the Partnership will be affected by a number of
factors that are beyond the Partnerships control. These factors include the price of crude oil and natural gas, the fluctuating supply of and demand for these products, competitive fuels, refining, transportation, extensive federal and state
regulations governing the production and sale of crude oil and natural gas, and other competitive conditions. It is impossible to predict with any certainty the future effect of these factors on the Partnership.

Results of Operations

Revenues and other
income for the three month period ended September 30, 2009 totaled $4,474,435, and consisted of oil and gas sales of $4,474,075 and interest income of $360.

Production volumes for the three month period ended September 30, 2009 were approximately 32,804 bbls of oil and 621,820 mcf of gas at corresponding average realized prices of $64.66 per bbl of oil and $3.78
per mcf of gas.

Expenses for the three month period ended September 30, 2009 totaled $2,003,426, consisting of lease operating
expenses in the amount of $289,822, production taxes of $195,910, depreciation, depletion, and amortization of $1,385,740, administrative and general expenses of $124,172 and asset retirement obligation accretion of $7,782. This resulted in net
income for the three month period ended September 30, 2009 of $2,471,009.

Revenues and other income for the nine month period
ended September 30, 2009 totaled $10,201,858, and consisted of oil and gas sales of $10,195,757 and interest income of $6,101.

Production volumes for the nine month period ended September 30, 2009 were approximately 88,504 bbls of oil and 1,404,707 mcf of gas at corresponding average realized prices of $53.62 per bbl of oil and $3.88 per mcf of gas.

##### Table of Contents

Expenses for the nine month period ended September 30, 2009 totaled $17,810,253, consisting of
lease operating expenses in the amount of $759,508, production taxes of $539,526, depreciation, depletion, and amortization of $3,751,306, administrative and general expenses of $245,732, and asset retirement obligation accretion of $17,963. In
addition, there was a cost ceiling write-down of $12,496,218 at March 31, 2009 due to lower oil and gas prices on that date. This resulted in a net loss for the nine month period ended September 30, 2009 of $7,608,395.

The Partnerships oil and gas production should increase during the remainder of 2009 as additional wells are completed and oil and gas
production is sold. Interest income should decrease in 2009 as available cash is utilized for drilling and equipping of wells.

The
Partnerships operations did not commence until the third quarter of 2008 thus operations were minimal for the quarter ending September 30, 2008. Therefore, the activities which occurred during the three month and nine month periods ended
September 30, 2008 are not comparable to the same periods of the current year.

New Accounting Pronouncements

FASB Accounting Standards Codification and the Hierarchy of Generally Accepted Accounting Principles. In June 2009, the FASB issued guidance on the
accounting standards codification and the hierarchy of generally accepted accounting principles. The accounting standards codification is intended to be the source of authoritative US GAAP and reporting standards as issued by the Financial
Accounting Standards Board (FASB). Its primary purpose is to improve clarity and use of existing standards by grouping authoritative literature under common topics. This Statement is effective for financial statements issued for interim
and annual periods ending after September 15, 2009. Effective July 1, 2009, the Partnership will describe the authoritative guidance used within the footnotes but will cease using numerical references. The accounting standards codification
does not change or alter existing US GAAP, and there is no expected impact on the Partnerships financial position, results of operations or cash flows.

Interim Disclosures about Fair Value of Financial Instruments. In April 2009, the FASB issued a staff position requiring fair value disclosures in both interim as well as annual financial statements in order to
provide more timely information about the effects of current market conditions on financial instruments. The guidance is effective for interim and annual periods ending after June 15, 2009. The implementation of this standard did not have a
material impact on the Partnerships financial position and results of operations.

Accounting for Transfers of Financial Assets.
In June 2009, the FASB issued an amendment to the accounting and disclosure requirements for transfers of financial assets. The guidance requires additional disclosures for transfers of financial assets and changes the requirements for derecognizing
financial assets. The guidance is effective for fiscal years beginning after November 15, 2009. The Partnership does not anticipate any impact of the guidance on its financial position and results of operations.

Modernization of Natural Gas and Oil Reporting. In January 2009, the SEC issued revisions to the natural gas and oil reporting disclosures,
Modernization of Oil and Gas Reporting, Final Rule (the Final Rule). In addition to changing the definition and disclosure requirements for natural gas and oil reserves, the Final Rule changes the requirements for determining
quantities of natural gas and oil reserves. The Final Rule also changes certain accounting requirements under the full cost method of accounting for natural gas and oil activities. The amendments are designed to modernize the requirements for the
determination of natural gas and oil reserves, aligning them with current practices and updating them for changes in technology. The Final Rule is effective for annual reports on Form10-K for fiscal years ending on or after December 31, 2009.
The Partnership currently is assessing the impact of adoption but does not expect that it will have a material impact on the Partnerships financial position, results of operations or cash flows.

Item 3.    Quantitative and Qualitative Disclosures about Market Risk



|1. | Interest Rate Risk
|-- | ------------------

The
Partnership Agreement allows borrowings from banks or other financial sources of up to 20% of the total capital contributions to the Partnership without investor approval. Should the Partnership elect to borrow monies for additional development
activity on Partnership properties, it will be subject to the interest rate risk inherent in borrowing activities. Changes in interest rates could significantly affect the Partnerships results of operations and the amount of net cash flow
available for partner distributions. Also, to the extent that changes in interest rates affect general economic conditions, the Partnership will be affected by such changes.



|2. | Commodity Price Risk
|-- | --------------------

The
Partnership does not expect to engage in commodity futures trading or hedging activities or enter into derivative financial instrument transactions for trading or other speculative purposes. The Partnership currently expects to sell a
significant amount of its production from successful oil and gas wells on a month-to-month basis at market prices. Accordingly, the Partnership is at risk for the volatility in commodity prices inherent in the oil and gas industry, and the level of
commodity prices will have a significant impact on the Partnerships results of operations. For the nine months ended September 30, 2009, a 10% change in the price received for natural gas production would have had an approximate $545,000
impact on revenue.



|3. | Exchange Rate Risk
|-- | ------------------

The
Partnership currently has no income from foreign sources or operations in foreign countries that would subject it to currency exchange rate risk. The Partnership does not currently expect to purchase any prospects located outside of either the
United States or United States coastal waters in the Gulf of Mexico.

Item 4.    Disclosure Controls
and Procedures

MD maintains a system of controls and procedures designed to provide reasonable assurance as to the reliability of the
financial statements and other disclosures included in this report, as well as to safeguard assets from unauthorized use or disposition. MDs Chief Executive Officer and Chief Financial Officer have evaluated the effectiveness of the design and
operation of its disclosure controls and procedures with the assistance and participation of other members of management. Based upon that evaluation, MDs Chief Executive Officer and Chief Financial Officer concluded that its disclosure
controls and procedures are effective for gathering, analyzing and disclosing the information the Partnership is required to disclose in the reports it files under the Securities Exchange Act of 1934 within the time periods specified in the
SECs rules and forms. Since MDs December 31, 2008 annual report on internal control over financial reporting, and for the quarter ended September 30, 2009, there have been no changes in MDs internal controls or in other
factors which have materially affected, or are reasonably likely to materially affect, the internal controls over financial reporting.
