MEWBOURNE ENERGY PARTNERS 08-A, L.P.

NOTES TO CONDENSED FINANCIAL STATEMENTS

(Unaudited)



|1. | Description of Business
|-- | -----------------------

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.



|2. | Summary of Significant Accounting Policies
|-- | ------------------------------------------

Reference is hereby made to the Registrants Annual Report on Form 10-K, 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.

New Accounting Pronouncements

On April 20, 2010, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2010-14, Accounting for
Extractive Activities - Oil and Gas: Amendments to Paragraph 932-10-S99-1 to make the definitions in Accounting Standards Codification (ASC) 932-10-S99-1 consistent with those in the SEC Final Rule, Modernization of Oil and Gas
Accounting. The Partnership adopted the new standards effective December 31, 2009. This update had no effect on the Partnerships financial position, results of operations or cash flows.



|3. | Accounting for Oil and Gas Producing Activities
|-- | -----------------------------------------------

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 June 30, 2010, no capitalized costs were excluded from amortization while at June 30, 2009, approximately $2.9 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 were no cost ceiling write-downs during the six months ended June 30, 2010. There was a cost ceiling write-down of $12,496,218 at March 31, 2009 but none at
June 30, 2009.

|4. | 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 six months ended June 30, 2010 and the
year ended December 31, 2009 is as follows:

|5. | 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, some of which will be included
in the full cost pool pursuant to Rule 4-10(c)(2) of Regulation S-X. 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.

|Operating costs, reporting and legal expenses, general and administrative expenses and all other costs |  | 70%         |  | 30% 



|(1) | Pursuant to the Program, MD must contribute 100% of organization and offering costs and lease acquisition costs which should approximate 20% of total capital
costs. To the extent that organization and offering costs and lease acquisition costs are less than 20% of total capital costs, MD is responsible for tangible drilling costs until its share of the Programs total capital costs reaches
approximately 20%. The Partnerships financial statements reflect its respective proportionate interest in the Program.

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 June 30, 2010, the Registrant owned working interests in 157 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 $4,758,321 at June 30, 2010.

During the six months ended June 30, 2010, the Partnership made cash distributions to the investor partners in the amount of $10,924,999 as
compared to $5,280,000 for the six months ended June 30, 2009. The Partnership expects that cash distributions will continue during 2010 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.

Oil and gas revenues. As shown
in the above table, total oil and gas sales rose by $2,454,386, a 71.7% increase, for the three months ended June 30, 2010 as compared to the three months ended June 30, 2009.

Of this increase, $652,781 and $722,448 were due to increases in the average prices of oil and gas sold, respectively. Average prices rose to
$74.15 from $54.08 per bbl and to $4.92 from $3.43 per mcf for the three months ended June 30, 2010 as compared to the three months ended June 30, 2009. In addition, $1,124,460 was due to an increase in the volume of gas sold by 228,325
mcf. The increase in volume of gas sold was primarily due to an increase in the number of wells.

Those increases were partially offset
by a decrease in revenue of $45,303 due to a decrease in the volume of oil sold. The volume sold decreased by 611 bbls for the three months ended June 30, 2010 as compared to the three months ended June 30, 2009.

Lease operations. Lease operating expense during the three month period ended June 30, 2010 increased to $432,838 from $237,835 due to the
additional number of wells in operation during the three month period ended June 30, 2010 as compared to the three months ended June 30, 2009.

Production taxes. Production taxes during the three month period ended June 30, 2010 increased to $295,292 from $207,385 for the three month
period ended June 30, 2009 due to higher revenue.

Administrative and general expense. Administrative and general expense for the
three month period ended June 30, 2010 increased to $333,066 from $87,489 for the three month period ended June 30, 2009. The overall increase was due to increased administrative expenses allocable to the Partnership for the three month
period ended June 30, 2010 and higher general expenses for reporting costs.

Depreciation, depletion and amortization.
Depreciation, depletion and amortization for the three month period ended June 30, 2010 increased to $1,477,298 from $1,168,928 for the three month period ended June 30, 2009 due to the additional number of wells.

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 six months ended June 30, 2009, a
10% change in the price received for natural gas production would have had an approximate $882,000 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.

Part II  Other Information

Item 1.   Legal Proceedings

From time to time, the Registrant may be a party to certain legal actions and claims arising in the ordinary course of business. While the outcome
of these events cannot be predicted with certainty, the Partnership does not expect these matters to have a material effect on its financial position or results of operations.
