                                     PART I

ITEM 1. DESCRIPTION OF BUSINESS ATLAS-ENERGY FOR THE NINETIES-PUBLIC #7 LTD.
(THE "PARTNERSHIP")

       We were formed under the Pennsylvania Revised Uniform Limited
Partnership Act on July 16, 1998, with Atlas Resources, Inc. ("Atlas") as our
managing general partner to drill natural gas development wells. We have no
employees and rely on our managing general partner for management. See Item 9
"Directors, Executive Officers and Significant Employees, Compliance With
Section 16(A) of the Exchange Act."

       We began our drilling activities under the drilling and operating
agreement, with our managing general partner acting as operator and general
drilling contractor, on our initial closing date of December 1, 1998. Our final
closing date was December 31, 1998, and we were funded with total subscriptions
of $11,988,350. We paid drilling costs under the drilling and operating
agreement in an amount equal to $11,988,350.

       A total of 57.5 net development wells were drilled and completed to the
Clinton/Medina geological formation in Pennsylvania and Ohio. These wells are
currently producing natural gas, which is our only product, and will continue
to do so until they are depleted at which time they will be plugged and
abandoned. No other wells will be drilled and thus no additional funds will
be required for drilling. Also, we did not begin paying operating and
maintenance costs for the wells under the drilling and operating agreement
until the wells began to produce, and our operating and maintenance costs
have been and are expected to be fulfilled through revenues generated from
our gas sales. During producing operations our managing general partner, as
operator, receives a monthly well supervision fee of $275 for each producing
well for which it has responsibility under the drilling and operating
agreement. The well supervision fee covers all normal and regularly recurring
operating expenses for the production, delivery and sale of gas, such as:

       -      well tending, routine maintenance and adjustment;

       -      reading meters, recording production, pumping, maintaining
              appropriate books and records;

       -      preparing reports to us and to government agencies; and

       -      collecting and disbursing revenues.

       The well supervision fees do not include costs and expenses related to
the purchase of equipment, materials or third party services and brine disposal.
If these costs are incurred, then our managing general partner as operator will
charge us at cost for third party services and materials and a reasonable charge
for services performed directly by it or its affiliates. The drilling and
operating agreement also gives our managing general partner as operator the
right at any time after three years from the date one of our wells has been
placed into production to retain $200 per month to cover future plugging and
abandonment costs of the well. Although we do not anticipate that we will have
to do so, any additional funds which may be 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 tine exceed 5% of our total subscriptions,
and no borrowings will be obtained from third parties.


                                       2

       We did not purchase and do not anticipate selling any producing wells. To
realize revenues our natural gas must be marketed. Our managing general partner
is responsible for selling our gas production, and its policy is to treat all
wells in a given geographic area equally. Our managing general partner
determines a weighted average selling price for all the gas sold in a geographic
area, such as the Mercer County area, by taking the money received from the sale
of all the gas sold by it and its affiliates, including us, in the area and
dividing by the volume of gas sold. Each of the managing general partner's
affiliates, including us, will then receive this gas price for all gas sold in
the area. All of our gas is to be sold as discussed in Item 2, "Properties -
Delivery Commitments."

       The marketing of our gas production is also affected by numerous factors
beyond our control and the effect of which we cannot accurately predict. These
factors include, but are not limited to, the following:

       -      the amount of domestic production and foreign imports of oil and
              gas;

       -      competition from other energy sources such as coal and nuclear
              energy;

       -      local, state and federal regulations regarding production and the
              cost of complying with applicable environmental regulations; and

       -      fluctuating seasonal supply and demand.

For example, the demand for natural gas is greater in the winter months than in
the summer months, which is reflected in a higher spot market price paid for the
gas. Also, increased imports of oil and natural gas have occurred and are
expected to continue. The free trade agreement between Canada and the United
States eased restrictions on imports of Canadian gas to the United States, and
the North American Free Trade Agreement eliminated trade and investment barriers
in the United States, Canada and Mexico. These imports could have an adverse
effect on both the price and volume of gas produced from the wells. In the past
reduced demand for natural gas and/or an excess supply of gas resulted in a
lower price paid for gas and difficulties in marketing gas.

       Governmental agencies regulate the production and transportation of our
natural gas. Generally, the regulatory agency in the state where a producing
natural gas well is located supervises production activities and the
transportation of natural gas sold intrastate. Our oil and gas operations are
regulated in Pennsylvania by the Department of Environmental Resources, Division
of Oil and Gas and in Ohio by the Ohio Department of Natural Resources, Division
of Oil and Gas which impose a comprehensive statutory and regulatory scheme on
oil and gas operations such as ours. Among other things, the regulations
involve:

       -      new well permit and well registration requirements, procedures and
              fees;

       -      minimum well spacing requirements;

       -      restrictions on well locations and underground gas storage;

       -      certain well site restoration, groundwater protection and safety
              measures;


                                       3
<PAGE>

       -      landowner notification requirements;

       -      certain bonding or other security measures;

       -      various reporting requirements;

       -      well plugging standards and procedures; and

       -      broad enforcement powers.

We do not expect that these regulations will have a material adverse impact upon
our operations, and we believe we have complied in all material respects with
applicable state regulations and will continue to do so.

       Gas prices are not regulated and in recent years gas prices have been
volatile. The price of our gas is based on supply, demand, BTU content,
pressure, location of the well and other factors.

       The Federal Energy Regulatory Commission ("FERC") regulates the
interstate transportation of natural gas, and it has sought to promote greater
competition in natural gas markets. Traditionally, natural gas has been sold by
gas producers to pipeline companies, which then would resell the gas to
end-users. FERC changed this market structure by requiring interstate pipeline
companies that transport gas for others to provide transportation services to
producers, distributors, and all other shippers of natural gas on a "first-come,
first-served" basis. This permits producers and other shippers to sell natural
gas directly to end-users and local distribution companies.

       FERC Order 636 requires gas pipeline companies to, among other things,
separate their sales services from their transportation services and provide an
open access transportation service that is comparable in quality for all gas
suppliers or producers. The premise behind FERC Order 636 was that the gas
pipeline companies had an unfair advantage over other gas suppliers because they
could bundle their sales and transportation services together. FERC Order 636 is
designed to ensure that no gas seller has a competitive advantage over another
gas seller because it also provides transportation services. We believe the
effect of FERC Order 636 has been to restructure the natural gas industry and
increase its competitiveness. Also, the Clean Air Act Amendments of 1990 contain
incentives for the future development of "clean alternative fuel," which
includes natural gas and liquefied petroleum gas for "clean-fuel vehicles." We
believe the amendments ultimately will have a beneficial effect on natural gas
markets and prices.

       Oil prices are not regulated and the price is subject to supply, demand,
competitive factors, the gravity of the crude oil, sulfur content differentials
and other factors. We expect to sell only small quantities of oil, if any.

       From time to time there are a number of proposals being considered in
Congress and in the legislatures and agencies of various states that if enacted
would significantly and adversely affect the oil and natural gas industry,
including us. The proposals involve, among other things, limiting the disposal
of waste water from wells and changes in the tax laws. We are unable to predict
what proposals, if any, will be enacted and their subsequent effect on our
activities.

       Our operations and costs may also be affected by various federal, state
and local laws covering the discharge of materials into the environment, or
otherwise relating to the protection of the environment. We


                                       4
<PAGE>

may generally be liable for cleanup costs to the United States Government under
the Federal Clean Water Act for oil or hazardous substance pollution and for
hazardous substance contamination under the Comprehensive Environmental
Response, Compensation and Liability Act of 1980. Our liability for
environmental cleanup costs or damages is unlimited in cases of willful
negligence or misconduct. In addition, the Environmental Protection Agency will
require us to prepare and implement spill prevention control and countermeasure
plans relating to the possible discharge of oil into navigable waters and will
require permits to authorize the discharge of pollutants into navigable waters.
State and local permits or approvals will also be needed with respect to
wastewater discharges and air pollutant emissions.

       Violations of environment-related lease conditions or environmental
permits can result in substantial civil and criminal penalties as well as
potential court injunctions curtailing operations. Compliance with these
statutes and regulations may cause delays or increase our production costs.
Because these laws and regulations are constantly being revised and changed we
are unable to predict the ultimate costs of complying with present and future
environmental laws and regulations, although we do not believe these costs will
be substantial. We are unable to obtain insurance to protect against many
environmental claims.

       We have not filed bankruptcy nor have we been involved in any material
reclassification, merger, consolidation, receivership or similar proceeding or
purchase or sale of a significant amount of assets not in the ordinary course of
business. Also, we have not and will not devote any funds to research and
development activities and there are no new products or services. We do not have
any patents, trademarks, licenses, franchises, concessions, royalty agreements
or labor contracts.

       ITEM 2. PROPERTIES

       DRILLING ACTIVITY. We drilled 57.5 net wells and all were productive. The
wells were completed by April 28, 1999. No further drilling activities will be
undertaken.

       The following table summarizes our drilling activity since our formation.
All the wells drilled were development wells which means a well drilled within
the proved area of an oil or gas reservoir to the depth of a stratigraphic
horizon known to be productive. We did not participate in any exploratory wells
which means a well drilled to find commercially productive hydrocarbons in an
unproved area; to find a new commercially productive horizon in a field
previously found to be productive of hydrocarbons at another horizon; or to
significantly extend a known prospect.

        A "dry hole" is an exploratory or a development well found to be
incapable of producing either oil or gas in sufficient quantities to justify
completion as an oil or gas well. A "productive well" is an exploratory or a
development well that is not a dry well.

        A "gross" well is a well in which we have a working interest. A "net"
well equals the actual working interest owned in one gross well divided by one
hundred. For example, a 50% working interest in a well is one gross well, but a
 .50 net well.

        PRODUCTION. The following table shows our net production in barrels
("bbls") of crude oil and in thousands of cubic feet ("mcf") of natural gas and
the costs and weighted average selling prices thereof, for the periods
indicated.

        (1)   The production shown in the table is determined by multiplying
              the gross production of properties in which we have an interest by
              the percentage of the leasehold interest we own less the royalty
              interests of others. All of the wells we own other than two are
              subject to a 12.5% landowner's royalty and have an 87.5% net
              revenue interest. Of the two remaining wells, one well is also
              subject to a 3.125% overriding royalty interest and has an 84.375%
              net revenue interest, and the other well has a second overriding
              royalty interest of 2.5% and has an 85% net revenue interest.

        (2)   The ratio of energy content of oil and gas (six mcf of gas equals
              one barrel of oil) was used to convert natural gas production into
              equivalent barrels of oil.

        (3)   The average sales price per mcf of gas sold by us was $2.36 in
              1999 after deducting all expenses, including transportation
              expenses.

        (4)   Production costs represent oil and gas operating expenses as
              reflected in our financial statements plus depreciation of support
              equipment and facilities.

       Estimated future net revenues represent estimated future gross revenues
from the production of proved reserves, net of estimated production and future
development costs, using prices and costs in effect as of December 31, 1999.
These prices were held constant throughout the life of the properties except
where different prices were fixed and determinable from applicable contracts.
These price assumptions resulted in a weighted average price of $2.92 per mcf
for gas over the life of the properties. The amounts shown do not reflect
non-property related costs, such as:

         -    general and administrative expenses;

         -    future income tax expense; and

         -    depreciation, depletion and amortization.

The present value of estimated future net revenues is calculated by discounting
estimated future net revenues by 10% annually. Prices used in calculating the
estimated future net revenues attributable to proved reserves do not necessarily
reflect market prices for oil and gas production after December 31, 1999. We can
provide no assurance of the following:

         -    that all of the proved reserves will be produced and sold within
              the periods assumed;

         -    that the assumed prices will actually be realized for the
              production; or

         -    that existing contracts will be honored.

The values expressed are estimates only, and may not reflect realizable values
or fair market values of the oil and gas ultimately extracted and recovered. The
standardized measure of discounted future net cash flows may not accurately
reflect proceeds of production to be received in the future from the sale of oil
and gas currently owned and does not necessarily reflect the actual costs that
would be incurred to acquire equivalent oil and gas reserves. For additional
information concerning oil and gas reserves and activities, see Note 9 to
the Financial Statements.

       "Proved reserves" means the 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 by contractual arrangements, but not
escalations based upon future conditions.

         -    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:

              -   that portion delineated by drilling and defined by gas-oil
                  and/or oil-water contacts, if any; and

              -   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.

         -    Reserves which 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.

         -    Estimates of proved reserves do not include the following:

              -   oil that may become available from known reservoirs but is
                  classified separately as "indicated additional reserves";

              -   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;

              -   crude oil, natural gas, and natural gas liquids, that may
                  occur in undrilled prospects; and

              -   crude oil, natural gas, and natural gas liquids, that may be
                  recovered from oil shales, coal, gilsonite and other such
                  sources.

       "Proved developed oil and gas reserves" means reserves that can be
expected to be recovered through existing wells with existing equipment and
operating methods. Additional oil and gas expected to be obtained through the
application of fluid injection or other improved recovery techniques for
supplementing the natural forces and mechanisms of primary recovery should be
included as "proved developed reserves" only after testing by a pilot project or
after the operation of an installed program has confirmed through production
response that increased recovery will be achieved.

       We do not have any proved undeveloped reserves. "Proved undeveloped
reserves" are reserves that are expected to be recovered either from:

              -   new wells on undrilled acreage; or


                                       8
<PAGE>

              -   from existing wells where a relatively major expenditure is
                  required for recompletion.

Reserves on undrilled acreage are limited to those drilling units offsetting
productive units that are reasonably certain of production when drilled. Proved
reserves for other undrilled units can be claimed only where it can be
demonstrated with certainty that there is continuity of production from the
existing productive formation. Under no circumstances should estimates for
proved undeveloped reserves 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 tests
in the area and in the same reservoir.

       Since December 31, 1999, we do not believe there has been a favorable or
adverse event which would cause a significant change in estimated reserves.
Reserves cannot be measured exactly as reserve estimates involve subjective
judgment. The estimates must be reviewed periodically and adjusted to reflect
additional information gained from reservoir performance, new geological and
geophysical data and economic changes. We have not filed any estimates (on a
consolidated basis) of our oil and gas reserves with, nor were such estimates
included in any reports to, any Federal or foreign governmental agency other
than the SEC within the 12 months before the date of this filing.

       ACREAGE. The following table sets forth, as of December 31, 1999, the
acres of developed and undeveloped oil and gas acreage in which we have an
interest.

       A "gross" acre is an acre in which we own a working interest. A "net"
acre equals the actual working interest owned in one gross acre divided by one
hundred. For example, a 50% working interest in an acre is one gross acre, but a
 .50 net acre. "Undeveloped acreage" is those lease acres on which wells have not
been drilled or completed to a point that would permit the production of
commercial quantities of oil and gas regardless of whether or not such acreage
contains proved reserves.

       DELIVERY COMMITMENTS. Our Managing General Partner anticipates that
substantially all of the natural gas produced by us in this and previous
programs in the Mercer County area will be sold to four (4) customers:

       1)     National Fuel Resources, Inc, a marketing subsidiary of National
              Fuel Gas Company (NFG) a publicly traded natural gas utility
              company listed on the New York Stock Exchange. NFG distributes
              natural gas to approximately 731,000 customers in southwestern New
              York and northwestern Pennsylvania through its regulated utility
              divisions.

       2)     Northeast Ohio Gas Marketing, Inc., a marketing subsidiary of
              First Energy Corporation (FE), a publicly traded electric utility
              company listed on the New York Stock Exchange. FE serves more than
              5.5 million people in central and northern Ohio and western
              Pennsylvania.

       3)     NUI Energy Brokers, Inc, a marketing subsidiary of NUI Corp.
              (NUI), a publicly traded natural gas utility company listed on the
              New York Stock Exchange. NUI distributes natural gas to
              approximately 372,000 customers in six states through its
              regulated utility divisions.

       4)     Wheatland Tube Company, a Pennsylvania Corporation, which connects
              directly to Atlas Pipeline Partners (APL), a Master Limited
              Partnership, publicly traded on the American Stock Exchange. APL
              is engaged in the ownership and operation of the majority of the
              natural pipeline gathering systems that serve the managing General
              Partner's production affiliates.

       All four (4) of the aforementioned Agreements involve monthly pricing
determined by industry standard index for each of the delivery locations
contemplated therein. In addition, the Agreement with Wheatland Tube Company
contains minimum and maximum prices which are fixed over each annual period.

       The Agreements with National Fuel Resources, Inc. and NUI Energy
Brokers, Inc. are standard industry contracts as suggested by the Gas
Industry Standards Board (GISB) for one-year terms commencing April 1, 2000.
Both Agreements are for firm fixed daily volumes (11,000 and 5,000 Dthd,
respectively) delivered to the facilities of National Fuel Gas Supply.

       The Agreement with Northeast Ohio Gas Marketing, Inc. is for a 10-year
term, which began on April 1, 1999, and provides that Northeast Ohio Gas
Marketing must take all of the gas produced by our managing general partner and
its affiliates. The agreement establishes price formula for each of the
delivery points for either the first one or two years of the Agreement. If, at
the end of the applicable period, our managing general partner and Northeast
Ohio Gas Marketing cannot agree to a new price, then our managing general
partner and its affiliates may arrange a sale of the gas to third parties.
However, they must first give Northeast Ohio Gas Marketing notice and an
opportunity to match the price. Thereafter, Northeast Ohio Gas Marketing and our
managing general partners will set the prices annually each November 30 subject
to the same terms. However, if there is no price agreement, then we can sell our
gas to third parties for the term of any unmatched third party offer. The
contracts with National Fuel Resources, Inc. and NUI Energy Brokers, Inc. are
pursuant to this right of refusal.

ITEM 3.       LEGAL PROCEEDINGS
        None.

ITEM 4.       SUBMISSION OF MATTERS TO A VOTE OF SECURITIES HOLDERS
        None.

                                     PART II

ITEM 5.  MARKET FOR REGISTRANT'S COMMON EQUITY AND RELATED STOCKHOLDER MATTERS

        MARKET INFORMATION. There is no established public trading market for
our units and we do not anticipate a market will develop. Our units may be
transferred only in accordance with the provisions of Article 6 of our
partnership agreement. The principal restrictions on transferability are as
follows:


                                       10


<PAGE>

        -   the consent of our managing general partner is required; and

        -   no transfer may be made which would result in materially adverse tax
            consequences to us or the violation of federal or state securities
            laws.

        An assignee may become a substituted limited partner or investor general
partner only upon meeting the following conditions:

        -   the assignor gives the assignee the right;

        -   our managing general partner consents to the substitution, which is
            in its absolute discretion;

        -   the assignee pays to us all costs and expenses incurred in
            connection with the substitution; and

        -   the assignee executes and delivers the instruments which are
            satisfactory to our managing general partner to effect the
            substitution and to confirm the assignee's agreement to be bound by
            all terms and provisions of the partnership agreement.

A substitute partner is entitled to all rights attributable to full ownership of
the assigned units, including the right to vote.

        HOLDERS.     As of December 31, 1999, there were 366 interestholders.

        DIVIDENDS. Our managing general partner reviews our accounts quarterly
to determine whether cash distributions are appropriate and the amount to be
distributed, if any. We distribute those funds to you and the other participants
which our managing general partner determines are not necessary for us to
retain. We will not advance or borrow for purposes of distributions if the
amount of the distributions would exceed our accrued and received revenues for
the previous four quarters, less paid and accrued operating costs with respect
to the revenues.

        The determination of the revenues and costs will be made in accordance
with generally accepted accounting principles, consistently applied, and cash
distributions to our managing general partner may only be made in conjunction
with distributions to you and the other participants.

        During the calendar year ending December 31, 1999, we distributed
$538,787 to you and the other participants and $116,352 to our managing
general partner.

                      MANAGEMENT'S DISCUSSION AND ANALYSIS
                             OR PLAN OF OPERATIONS

           Management's discussion and analysis should be read in conjunction
       with the financial statements and notes thereto.

       RESULTS OF OPERATIONS

       TWELVE MONTHS ENDED DECEMBER 31, 1999

           The net loss for the twelve months ended December 31, 1999 was
       $7,075,410.

           The Partnership commenced production in January, 1999. Natural gas
       sales revenue for the twelve months ended December 31, 1999 amounted to
       $1,564,581, based on gas production of 662,125 Mcf. The average sales
       price for gas production during this period was $2.36/Mcf.

           The net loss includes an impairment of oil and gas properties.
       This non-cash charge to earnings amounted to $6,600,718. Refer to Note #2
       in the Notes to Financial Statements.

       QUARTER ENDED DECEMBER 31, 1999

           The net loss for the quarter ended December 31, 1999 was $5,561,172.

           Natural gas sales revenue for the quarter ended December 31, 1999
       amounted to $439,625. Gas production was 96,842 Mcf; and the average
       sales price was $2.59/Mcf.

           The net loss for the quarter includes an impairment of oil and gas
       properties. This non-cash charge to earnings amounted to $6,600,718.
       Refer to Note #2 in the Notes to Financial Statements.

       FINANCIAL CONDITION

       LIQUIDITY

           Cash provided by operating activities during the twelve months ended
       December 31, 1999 results primarily from sales of natural gas. The
       Partnership's working capital increased from $29,592 at December 31, 1998
       to $639,715 at December 31, 1999. The increase is attributable to the
       commencement of natural gas production for new wells turned on-line
       during the year, which resulted in higher receivables in connection with
       sales of gas produced.

       CAPITAL RESOURCES

           There were no new material commitments for capital expenditures
       during the period and the Partnership does not expect any in the
       foreseeable future.

ITEM 7.       FINANCIAL STATEMENTS

        Our Financial Statements for the last fiscal year, together with the
opinion of the accountants thereon, are on pages 20 through 32 of this report.

ITEM 8.     CHANGES IN AND DISAGREEMENTS ON ACCOUNTING AND FINANCIAL DISCLOSURE

        In December 1998, we engaged Grant Thornton, L.L.P., as the independent
certified public accountants to audit our financial statements for the calendar
year ended December 31, 1998. At that time, we chose not to renew the engagement
of McLaughlin & Courson, who previously served as our independent certified
public accountants. The decision to change accountants was approved by our
managing general partner.

        During the period since our formation on July 16, 1998, and each
subsequent interim period, there were no disagreements with the former
accountants on any matter of accounting principles or practices, financial
statement disclosure, or auditing scope or procedure, which disagreements, if
not resolved to the satisfaction of the former accountants, would have caused
them to make reference in connection with their report to the subject matter of
the disagreements.

        The report of the former principal accountants on our financial
statements since our formation contained no adverse opinion or disclaimer of
opinion, nor was it qualified or modified as to uncertainty, audit scope, or
accounting principles.

                                    PART III

ITEM 9. DIRECTORS, EXECUTIVE OFFICERS AND SIGNIFICANT EMPLOYEES, COMPLIANCE WITH
SECTION 16(A) OF THE EXCHANGE ACT

       RESPONSIBILITIES OF ATLAS. We have no employees and rely on our managing
general partner, which also serves as driller-operator of the wells, for
management. Our managing general partner has complete and exclusive discretion
and control over our operations and activities and makes all of our decisions
affecting the wells which we have developed. Our managing general partner
provides continuing review and analysis of all wells and monitors all
expenditures and commitments made on our behalf. In addition, our managing
general partner performs administrative services relating to our funding and
operation, participant reporting, financial budgeting and record keeping.


                                       13
<PAGE>

       Because we have no equity securities registered pursuant to Section 12 of
the Exchange Act, there is no required compliance with Section 16(A) of the
Exchange Act.

       BUSINESS OF ATLAS. Our managing general partner was incorporated in 1979
and its affiliate, Atlas Energy Group, Inc., an Ohio corporation, was
incorporated in 1973. As of December 31, 1999, our managing general partner and
its affiliates operated approximately 3,400 oil or natural gas wells located in
Ohio, Pennsylvania, and New York.

        On September 29, 1998, Atlas Group, the former parent company of our
managing general partner, merged into Atlas America, Inc., a newly formed
wholly-owned subsidiary of Resource America, Inc. Resource America is a
publicly-traded company principally engaged in real estate finance, equipment
leasing and energy and energy finance. Atlas America is continuing the existing
business of Atlas Group and is headquartered at 311 Rouser Road, Moon Township,
Pennsylvania 15108 which is also the managing general partner's primary office.

       The managing general partner and its affiliates under Atlas America
employ a total of approximately 154 persons, consisting of 4 geologists, 9
landmen, 4 engineers, 49 operations staff, 12 accounting, 1 gas marketing, and
18 administrative personnel. The balance of the personnel are engineering,
pipeline and field supervisors.

(1)    Resource Energy and Viking Resources, which are subsidiaries of Resource
       America, are also engaged in the oil and gas business. In the near term,
       it is expected that both Resource Energy and Viking Resources will retain
       their separate corporate existence, however, Atlas America will manage
       the assets and employees of both including sharing common employees.
       Also, many of the officers and directors of our managing general partner
       serve as officers and directors of those entities.

(2)    Atlas Pipeline Partners, L.P. (and Atlas Pipeline Operating Partnership)
       is a master limited partnership formed by a subsidiary of Atlas America
       as managing general partner to acquire a natural gas gathering system and
       related facilities from Resource Energy, Atlas America, and Viking
       Resources. The gathering system consists of approximately 888 miles of
       intrastate pipelines located in Pennsylvania, Ohio, and New York. We
       anticipate that this master limited partnership will gather and deliver
       natural gas produced by us in the Mercer County area to either
       public utility or interstate pipeline systems or industrial end-users in
       the area.

ITEM 10.      EXECUTIVE COMPENSATION

        We have no employees and rely on the employees of the managing general
partner and its affiliates for services. Thus, we did not directly pay any
compensation to the employees of our managing general partner for the last
fiscal year. See Item 12, "Interest of Management and Others in Certain
Transactions," below for compensation which we paid to our managing general
partner.

ITEM 11.      SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT

        As of December 31, 1999, we had issued and outstanding 1,200 units. No
officer or director of our managing general partner owns any units. Also, no
partner beneficially owns more than 10% of our outstanding units.

       Resource America owns 100% of the common stock of Atlas America, which
owns 100% of the common stock of AIC, Inc., which owns 100% of the common stock
of our managing general partner.

ITEM 12.      CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

       OIL AND GAS REVENUES. Our managing general partner is allocated 31% of
our oil and gas revenues in return for having paid organization and offering
costs equal to 15% of our subscriptions, 51% of tangible costs and contributing
all leases for a total capital contribution of $3,852,439. During the calendar
year ending December 31, 1999, our managing general partner received $404,405
from our oil and gas revenues.

       LEASES. Our managing general partner contributed to us (at the lower of
fair market value or its cost of the prospects) 58 undeveloped prospects to
drill approximately 57.5 net wells. Our managing general partner received a
credit in the amount of $208,800 for these prospects. During 1999, our managing
general partner did not enter into any further lease transactions with us and
none are anticipated.

       ADMINISTRATIVE COSTS. Our managing general partner and its affiliates
receive an unaccountable, fixed payment reimbursement for their administrative
costs of $75 per well per month, which is proportionately reduced if we acquired
less than 100% of the working interest in a well. During the calendar year
ending December 31, 1999, our managing general partner received $37,628 for
its administrative costs.

       DIRECT COSTS. Our managing general partner and its affiliates are
reimbursed for all direct costs expended on our behalf. During the calendar year
ending December 31, 1999, our managing general partner received $126,004 as
reimbursement for direct costs.

       DRILLING CONTRACTS. On December 1, 1998, as amended on December 31, 1998,
we entered into a drilling contract with our managing general partner to drill
and complete 57.5 net wells. We paid the


                                       16
<PAGE>

managing general partner for drilling and completing our wells an amount equal
to $39.15 per foot to the depth of the well at its deepest penetration,
proportionately reduced if we acquired less than 100% of the working interest in
a well. The total amount received by our managing general partner was
$11,988,350 for drilling and completing the wells. During 1999, we did not enter
into any further drilling transactions and none are anticipated.

       PER WELL CHARGES. Our managing general partner, as operator, is
reimbursed at actual cost for all direct expenses incurred on our behalf and
receives well supervision fees for operating and maintaining the wells during
producing operations in the amount of $275 per well per month subject to an
annual adjustment for inflation. The well supervision fees are proportionately
reduced to the extent we acquired less than 100% of the working interest in a
well. During the calendar year ending December 31, 1999, our managing general
partner received $134,046 for well supervision fees.

       As operator our managing general partner charges us at cost for third
party services and materials provided for each well which has been placed in
operation.

       TRANSPORTATION AND MARKETING FEES. We pay a combined transportation and
marketing charge at a competitive rate, which is currently $0.29 for each mcf
transported, to the managing general partner and its affiliates, for natural gas
which we produce. See footnote 2 to the Organizational Diagram for a discussion
of the change of ownership of the gathering system. For the year ended December
31, 1999, we paid $192,016.

       OTHER COMPENSATION. We will reimburse our managing general partner for
any loan it may make to us at a competitive rate of interest. If our managing
general partner provides equipment, supplies and other services to us it may do
so at competitive industry rates. For the calendar year ending December 31,
1999, our managing general partner did not advance any funds nor did it provide
any equipment, supplies or other services.

               REPORT OF INDEPENDENT CERTIFIED PUBLIC ACCOUNTANTS



To the Partners
ATLAS-ENERGY FOR THE NINETIES - PUBLIC #7 LTD.
A PENNSYLVANIA LIMITED PARTNERSHIP

We have audited the accompanying balance sheets of Atlas-Energy for The
Nineties - Public #7 Ltd., A Pennsylvania Limited Partnership, as of December
31, 1999 and 1998, and the related statements of operations, changes in
partners' capital accounts and cash flows for the year ending December 31,
1999 and the period July 16, 1998 (date of formation) to December 31, 1998.
These financial statements are the responsibility of the Partnership's
management. Our responsibility is to express an opinion on these financial
statements based on our audits.

We conducted our audits in accordance with auditing standards generally
accepted in the United States. Those standards require that we plan and
perform the audit to obtain reasonable assurance about whether the financial
statements are free of material misstatement. An audit includes examining, on
a test basis, evidence supporting the amounts and disclosures in the financial
statements. An audit also includes assessing the accounting principles used
and significant estimates made by management, as well as evaluating the
overall financial statement presentation. We believe that our audits provide a
reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the financial position of Atlas-Energy for The Nineties
-Public #7 Ltd. as of December 31, 1999 and the results of its operations,
changes in partners' capital accounts and cash flows for the year ending
December 31, 1999 and the period July 16, 1998 (date of formation) to December
31, 1998, in conformity with accounting principles generally accepted in the
United States.

                          NOTES TO FINANCIAL STATEMENTS

                           December 31, 1999 and 1998



A summary of significant accounting policies consistently applied in the
preparation of the accompanying financial statements follows:

1.   NATURE OF OPERATIONS

     Atlas-Energy for the Nineties - Public #7 Ltd. (the "Partnership") is a
     Pennsylvania Limited Partnership which includes Atlas Resources, Inc.
     ("Atlas") of Pittsburgh, Pennsylvania, as Managing General Partner and
     Operator, and 366 Limited Partners. The Partnership was formed on July 16,
     1998 to drill and operate gas wells located primarily in Mercer County,
     Pennsylvania. At December 31, 1999, the Partnership had various working
     interests in 61 wells.

2.   SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

     BASIS OF ACCOUNTING

     The financial statements are prepared in accordance with generally
     accepted accounting principles.

     Certain reclassifications have been made to the 1998 financial statements
     to conform with the 1999 presentation.

     OIL AND GAS WELLS AND LEASES

     The Partnership uses the successful efforts method of accounting for oil
     and gas producing activities. Costs to acquire mineral interests in oil
     and gas properties and to drill and equip wells are capitalized.
     Depreciation and depletion is computed on a field-by-field basis by the
     unit-of-production method based on periodic estimates of oil and gas
     reserves.

     Undeveloped leaseholds and proved properties are assessed periodically or
     whenever events or circumstances indicate that the carrying amount of
     these assets may not be recoverable. Proved properties are assessed based
     on estimates of future cash flows. As a result of this assessment, an
     impairment loss of $6,600,718 was recognized in 1999.

     USE OF ESTIMATES

     The preparation of financial statements in conformity with generally
     accepted accounting principles requires management to make estimates and
     assumptions that affect the amounts reported in the financial statements
     and accompanying notes. Actual results could differ from those estimates.

                    NOTES TO FINANCIAL STATEMENTS - CONTINUED

                           December 31, 1999 and 1998




2.   SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

     NEW ACCOUNTING STANDARDS

     In 1998, the AICPA issued Statement of Position 98-5 ("SOP 98-5"),
     REPORTING ON THE COSTS OF START-UP ACTIVITIES. This statement requires
     costs of start-up activities and organization costs, as defined, to be
     expensed as incurred. The Partnership adopted the provisions of SOP 98-5
     effective January 1, 1999 and, accordingly, wrote off the unamortized
     organization costs of $20,000 as a charge to operations on January 1,
     1999, which is reflected as a cumulative effect of a change in accounting
     principle in the 1999 Statement of Operations.


3.   FEDERAL INCOME TAXES

     The Partnership is not treated as a taxable entity for federal income tax
     purposes. Any item of income, gain, loss, deduction or credit flows
     through to the partners as though each partner had incurred such item
     directly. As a result, each partner must take into account his pro rata
     share of all items of partnership income and deductions in computing his
     federal income tax liability.


4.   PARTICIPATION IN REVENUES AND COSTS

     Atlas and the other partners generally participate in revenues and costs
in the following manner:

     Depreciation and depletion of natural gas and oil properties are expensed
     at unit cost rates calculated annually based on the estimated volume of
     recoverable gas and the related costs.

     (3) RESERVE INFORMATION

     The information presented below represents estimates of proved natural gas
     and oil reserves. Reserves are estimated in accordance with guidelines
     established by the Securities and Exchange Commission and the Financial
     Accounting Standards Board which require that reserve estimates be
     prepared under existing economic and operating conditions with no
     provision for price and cost escalation except by contractual
     arrangements. Proved reserves are estimated quantities of oil and natural
     gas which geological and engineering data demonstrate with reasonable
     certainty to be recoverable in future years from known reservoirs. Proved
     developed reserves and are those which are expected to be recovered
     through existing wells with existing equipment and operating methods. All
     reserves are proved developed reserves and are located in the Appalachian
     Basin area.

     There are numerous uncertainties inherent in estimating quantities of
     proved reserves and in projecting future net revenues and the timing of
     development expenditures. The reserve data presented represents estimates
     only and should not be construed as being exact. In addition, the
     standardized measures of discounted future net cash flows may not
     represent the fair market value of the Company's oil and gas reserves or
     the present value of future cash flows of equivalent reserves, due to
     anticipated future changes in oil and gas prices and in production and
     development costs and other factors for which effects have not been
     provided.

     (4) STANDARD MEASURE OF DISCOUNTED FUTURE CASH FLOWS

     The standardized measure of discounted future net cash flows is
     information provided for the financial statement user as a common base
     for comparing oil and gas reserves of enterprises in the industry. The
     following schedule presents the standardized measure of estimated
     discounted future net cash flows from the Company's proved reserves.
     Estimated future cash flows are determined by using the weighted average
     price received for the month of December 1999 adjusted only for fixed and
     determinable increases in natural gas prices provided by contractual
     agreements. The standardized measure of future net cash flows was
     prepared using the prevailing economic conditions existing at December
     31, 1999 and such conditions continually change. Accordingly, such
     information should not serve as a basis in making any judgment on the
     potential value of recoverable reserves or in estimating future results
     of operations.
