                      (A Pennsylvania Limited Partnership)

                    NOTES TO FINANCIAL STATEMENTS (Unaudited)
                 FOR THREE MONTHS ENDED MARCH 31, 2002 AND 2001

NOTE 1 - MANAGEMENT'S OPINION REGARDING INTERIM FINANCIAL STATEMENTS

         The financial statements of Atlas America Public #9 Ltd. (the
Partnership) for the three months ended March 31, 2002 and 2001 are unaudited.
Certain information and footnote disclosures normally included in financial
statements prepared in accordance with accounting principles generally accepted
in the United States of America have been condensed or omitted in this Form
10-QSB pursuant to the rules and regulations of the Securities and Exchange
Commission. However, in the opinion of management, these interim financial
statements include all the necessary adjustments to fairly present the results
of the interim periods presented. The unaudited interim financial statements
should be read in conjunction with the audited financial statements included in
the Partnership's Form 10-K for the calendar year ended December 31, 2001. The
results of operations for the three months ended March 31, 2002 may not
necessarily be indicative of the results of operations for the full calendar
year ending December 31, 2002.

        Certain reclassifications have been made to the financial statements for
the three months ended March 31, 2001 to conform with the three months ended
March 31, 2002.

NOTE 2 - NEW ACCOUNTING STANDARD

         In July 2001, the Financial Accounting Standards Board issued SFAS No.
143, " Accounting for Asset Retirement Obligations". SFAS No. 143 requires
entities to record the fair value of a liability for an asset retirement
obligation in the period in which it is incurred and a corresponding increase in
the carrying amount of the related long-lived asset and will be effective for
fiscal years beginning after July 15, 2002. The Partnership is required to adopt
SFAS No. 143 effective January 1, 2003 and has not yet determined the impact of
this new accounting standard.

NOTE 3 - TRANSACTIONS WITH ATLAS AND ITS AFFILIATES

         The Partnership has entered into the following significant transactions
with Atlas Resources, Inc. (Atlas), the Managing General Partner, and its
affiliates as provided under the Partnership agreement:

         o        Administrative costs payable to Atlas at $75 per well per
                  month. Administrative costs incurred in the three months ended
                  March 31, 2002 and 2001 were $17,900 and $800, respectively.

         o        Monthly well supervision fees payable to Atlas at $275 per
                  well per month for operating and maintaining the wells. Well
                  supervision fees incurred for the three months ended March 31,
                  2002 and 2001 were $58,700 and $1,200, respectively.

         o        Transportation fees paid to Atlas of $.29 per mcf.
                  Transportation costs incurred for the three months ended March
                  31, 2002 and 2001 were $101,100 and $2,600, respectively.

         o        As managing general partner, Atlas performs all administrative
                  and management functions for the Partnership including billing
                  revenues and paying expenses. Accounts receivable - affiliate
                  on the balance sheet represents the net production revenues
                  due from Atlas.

             NOTES TO FINANCIAL STATEMENTS (Unaudited) - (Continued)
                 FOR THREE MONTHS ENDED MARCH 31, 2002 AND 2001


NOTE 4 - HEDGING ACTIVITIES

         Atlas enters into natural gas futures and option contracts to hedge the
Partnership's exposure to changes in natural gas prices. At any point in time,
such contracts may include regulated New York Mercantile Exchange ("NYMEX")
futures and options contracts and non-regulated over-the-counter futures
contracts with qualified counter parties. NYMEX contracts are generally settled
with offsetting positions, but may be settled by the delivery of natural gas.
Although hedging provides Atlas and its affiliates, including the Partnership,
some protection against falling prices, these activities could also reduce the
potential benefits of price increases, depending upon the instrument. Atlas does
not hold derivative instruments for trading purposes.

         Effective January 1, 2001, the Partnership adopted Statement of
Financial Accounting Standards No. 133 ("SFAS 133") Accounting for Derivative
Instruments and Hedging Activities (as amended by SFAS 138). This statement
establishes accounting and reporting standards for derivative instruments and
hedging activities. The statement requires that all derivative financial
instruments are recognized in the financial statements as either assets or
liabilities measured at fair value. Changes in the fair value of derivative
financial instruments are recognized in income or other comprehensive income,
depending on their classification. Upon adoption of SFAS 133, the Partnership
did not incur any transition adjustments to earnings.

         At March 31, 2002, Atlas had natural gas futures and option contracts
covering approximately 250,000 dekatherms ("Dth") of the Partnership's gas
production maturing April 2002 through September 2003 at a combined average
price of $3.23 per Dth. As these contracts qualify and have been designated as
cash flow hedges, any gains or losses resulting from market price changes are
deferred and recognized as a component of sales revenues in the month the gas is
sold. Gains or losses on futures contracts are determined as the difference
between the contract price and a reference price, generally prices on NYMEX. The
Partnership's net unrealized loss related to open NYMEX contracts was $108,200
at March 31, 2002. The unrealized loss of $108,200 at March 31, 2002 has been
recorded as a liability on the Partnership's 2002 Balance Sheet and in partners'
capital as accumulated other comprehensive income. As of March 31, 2002, $68,200
of the unrealized loss is expected to be reclassified to earnings during the
next 12 months. The Partnership did not recognize any losses on settled
contracts covering natural gas production for the three months ended March 31,
2002 or 2001. The Partnership recognized no gains or losses during the three
months ended March 31, 2002 for hedge ineffectiveness or as a result of the
discontinuance of cash flow hedges. The Partnership assesses the effectiveness
of its hedges based on changes in the derivates' intrinsic value.

         Net Earnings. During the three months ended March 31, 2002, we had net
earnings of $243,200 as compared with net earnings for the three months ended
March 31, 2001 of $34,000.

         Revenues. Our natural gas revenues were $1,194,000 for the three months
ended March 31, 2002, an increase of $1,142,300 from $51,700 for the three
months ended March 31, 2001, directly attributable to the fact that the majority
of the Partnership wells were not put into production until after March 31,
2001.

         Expenses. Production expenses for the three months ended March 31, 2002
amounted to $198,300 compared to $4,300 for the three months ended March 31,
2001, an increase of $194,000. This increase is directly attributable to the
fact that the majority of the Partnership wells were not put into production
until after March 31, 2001.

         Depletion and depreciation of oil and gas properties as a percentage of
oil and gas revenues was 60% in the three months ended March 31, 2002 compared
to 24% for the three months ended March 31, 2001. This percentage change is
directly attributable to changes in our oil and gas reserve quantities, product
prices and reduction in the depletable cost basis of oil and gas properties.

         Liquidity and Capital Resources. At March 31, 2002 we had working
capital of $1,667,000 a decrease of $234,200 from $1,901,200 at December 31,
2001. Cash increased $481,500 from December 31, 2001.

         There were no new material commitments for us to make capital
expenditures during the period and we do not expect any in the foreseeable
future. Any additional funds, if required will be obtained from production
revenues or borrowings from our managing general partner or its affiliates,
which are not contractually committed to make a loan. The amount that may be
borrowed may not at any time exceed 5% of our total subscriptions, and no
borrowings will be obtained from third parties.

         Recent Accounting Pronouncement. In July 2001, the Financial Accounting
Standards Board issued SFAS No. 143, " Accounting for Asset Retirement
Obligations". SFAS No. 143 requires entities to record the fair value of a
liability for an asset retirement obligation in the period in which it is
incurred and a corresponding increase in the carrying amount of the related
long-lived asset and will be effective for fiscal years beginning after July 15,
2002. The Partnership is required to adopt SFAS No. 143 effective January 1,
2003 and has not yet determined the impact of this new accounting standard.

ITEM 3.  QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

         The primary objective of the following information is to provide
forward-looking quantitative and qualitative information about our potential
exposure to market risks. The term "market risk" refers to the risk of loss
arising from adverse changes in interest rates and oil and gas prices. The
disclosures are not meant to be precise indicators of expected future losses,
but rather indicators of reasonable possible losses. This forward-looking
information provides indicators of how we view and manage our ongoing market
risk exposures. All of our market risk sensitive instruments were entered into
for purposes other than trading.

         Commodity Price Risk. Our major market risk exposure in commodities is
the pricing applicable to our oil and gas production. Realized pricing is
primarily driven by the prevailing worldwide price for crude oil and spot market
prices applicable to U.S. natural gas production. Pricing for oil and gas
production has been volatile and unpredictable for many years. We periodically
enter into financial hedging transactions with respect to a portion of our
projected gas production. These financial hedging transactions are intended to
reduce the impact of oil and gas price fluctuations. Realized gains and losses
from the settlement of these hedges are recognized in gas revenues when the
associated production occurs. The gains and losses realized as a result of
hedging are substantially offset in the market when the commodity is delivered.
We do not hold or issue derivative instruments for trading purposes.

         Effective January 1, 2001, we adopted Statement of Financial Accounting
Standards No. 133, "Accounting for Derivative Instruments and Hedging
Activities" (as amended by SFAS No. 138). As of March 31, 2002, we had gas
hedges in place covering 250,000 dekatherm maturing through September 2003. The
fair value of these hedges is a $108,200 liability at March 31, 2002 and is
included on our balance sheet and represents the estimated amount that would
have been realized had the hedges been terminated on that date. As these
contracts qualify and have been designated as cash flow hedges, gains and losses
on them resulting from market price changes are determined monthly and reflected
in accumulated other comprehensive income until the month in which the hedged
production is sold. At that time, the amount included in accumulated other
comprehensive income related to the sold production is closed to production
revenues. Gains or losses on open and closed hedging transactions are determined
as the difference between the contract price and a reference price, generally
closing prices on NYMEX.
