             PROSPECTUS DATED APRIL 7, 2006 (SUBJECT TO COMPLETION)

                      ATLAS AMERICA PUBLIC #15-2005 PROGRAM

  Up to 14,265.5 Investor General Partner Units and 14,265.5 converted Limited
   Partner Units and up to 507.1 Limited Partner Units, which are collectively
                referred to as the "Units," at $10,000 per Unit

             $2 Million (200 Units) Minimum Aggregate Subscriptions
          $147,726,000 (14,772.6 Units) Maximum Aggregate Subscriptions

Atlas America Public #15-2005 Program is a series of up to three limited
partnerships which will drill primarily natural gas development wells. The first
partnership in the program, Atlas America Public #15-2005(A) L.P., completed its
offering on December 31, 2005 and received offering proceeds of $52,245,720 for
the sale of 5,227.40 units. This prospectus relates to the offering of
securities of the program's remaining two limited partnerships, Atlas America
Public #15-2006(B) L.P. and Atlas America Public #15-2006(C) L.P. The last
limited partnership in the program, Atlas America Public #15-2006(D) L.P., will
not be offered. See "Terms of the Offering - Subscription to a Partnership,"
beginning on page 36, for a detailed description of the offering of these
limited partnerships. All of the limited partnerships will be managed by Atlas
Resources, LLC of Pittsburgh, Pennsylvania.

If you invest in a partnership, you will not have any interest in any of the
other partnerships unless you also make a separate investment in the other
partnerships.

The units will be offered on a "best efforts" "minimum-maximum" basis. This
means the broker/dealers must sell at least 200 units and receive subscription
proceeds of at least $2 million in order for a partnership to close, and they
must use only their best efforts to sell the remaining units in the partnership.

Subscription proceeds for each partnership will be held in an interest bearing
escrow account until $2 million has been received. The offering of Atlas America
Public #15-2006(B) L.P. and Atlas America Public #15-2006(C) L.P. will not
extend beyond December 31, 2006. If the minimum subscription proceeds are not
received by a partnership's offering termination date, then your subscription
will be promptly returned to you from the escrow account with interest and
without deduction for any fees.

The Offering: In addition to the information in the table below for not less
than 95% of the units (14,033.97 units), up to 5% of the units (738.63 units),
in the aggregate, may be sold at $8,950 per unit to the managing general
partner, its officers, directors and affiliates, and investors who buy units
through the officers and directors of the managing general partner; or at $9,300
per unit to registered investment advisors and their clients, and selling agents
and their registered representatives and principals. These discounted prices
reflect certain fees, sales commissions and reimbursements which will not be
paid for these sales. (See "Plan of Distribution.") To the extent that units are
sold at discounted prices, a partnership's subscription proceeds will be
reduced.

Proceeds to partnership              $10,000     $2,000,000     $147,726,000
- -------
(1) These fees, sales commissions and reimbursements will be paid by the
    managing general partner as a part of its capital contribution and not from
    subscription proceeds.

(2) The first partnership in the program, Atlas America Public #15-2005(A) L.P.,
    completed its offering on December 31, 2005 and received offering proceeds
    of $52,245,720, which includes 40.40 units sold at the discounted prices
    described above. Thus, the total remaining maximum subscriptions from the
    original $200 million, based on the number of units previously sold, are
    $147,726,000, which is 14,772.6 units at $10,000 per unit and assumes no
    units are sold at the discounted prices described above.



o  A partnership's drilling operations involve the possibility of a substantial
   or partial loss of your investment because of wells which are productive, but
   do not produce enough revenue to return the investment made and dry holes.

o  A partnership's revenues are directly related to the ability to market the
   natural gas and natural gas and oil prices, which are volatile and uncertain.
   If natural gas and oil prices decrease, then your investment return will
   decrease.

o  Unlimited joint and several liability for partnership obligations if you
   choose to invest as an investor general partner until you are converted to a
   limited partner.

o  Lack of liquidity or a market for the units, which makes it extremely
   difficult for you to sell your units.

                             SUMMARY OF THE OFFERING

This is a summary and does not include all of the information which may be
important to you. You should read the entire prospectus and the attached
exhibits and appendix before you decide to invest. Throughout this prospectus
when there is a reference to you it is a reference to you as a potential
investor or participant in a partnership.

BUSINESS OF THE PARTNERSHIPS AND THE MANAGING GENERAL PARTNER
Atlas America Public #15-2005 Program, which is sometimes referred to in this
prospectus as the "program," consists of up to three Delaware limited
partnerships. The first partnership in the program, Atlas America Public
#15-2005(A) L.P., completed its offering on December 31, 2005 and received
offering proceeds of $52,245,720 for the sale of 5,227.40 units. This prospectus
relates to the offering of the remaining unsold 14,772.60 units by the program's
remaining two limited partnerships, Atlas America Public #15-2006(B) L.P. and
Atlas America Public #15-2006(C) L.P. The last limited partnership in the
program, Atlas America Public #15-2006(D) L.P., will not be offered. These
remaining two limited partnerships are sometimes referred to in this prospectus
in the singular as a "partnership" or in the plural as the "partnerships." Units
of Atlas America Public #15-2006(B) L.P. and Atlas America Public #15-2006(C)
L.P. will be offered and sold in a series in 2006, although the managing general
partner has the sole discretion to sell up to and including all of the remaining
units in Atlas America Public #15-2006(B) L.P. and not offer and sell any units
in Atlas America Public #15-2006(C) L.P. See "Terms of the Offering" for a
discussion of the terms and conditions involved in making an investment in a
partnership.

Each partnership in the program will be a separate business entity from the
other partnerships. A limited partnership agreement will govern the rights and
obligations of the partners of each partnership. A form of the limited
partnership agreement is attached to this prospectus as Exhibit (A). For a
summary of the material provisions of the limited partnership agreement which
are not covered elsewhere in this prospectus see "Summary of Partnership
Agreement." You will be a partner only in the partnership in which you invest.
You will have no interest in the business, assets or tax benefits of the other
partnerships unless you also invest in the other partnerships. Thus, your
investment return will depend solely on the operations and success or lack of
success of the partnership in which you invest.

The offering proceeds of each partnership will be used to drill primarily
natural gas development wells in the Appalachian Basin located primarily in
western Pennsylvania, eastern and southern Ohio and north central Tennessee as
described in "Proposed Activities." A development well means a well drilled
within the proved area of a natural gas or oil reservoir to the depth of a
stratigraphic horizon known to be productive. Currently, the partnerships do not
hold any interests in any properties or prospects on which the wells will be
drilled.

The managing general partner of each partnership is Atlas Resources, LLC, a
Pennsylvania limited liability company, which was originally formed as a
corporation in 1979 and then changed to a limited liability company in March,
2006. The managing general partner is sometimes referred to in this prospectus
as "Atlas Resources." As set forth in "Prior Activities," the managing general
partner has sponsored and serves as managing general partner of 36 private
drilling partnerships and 15 public drilling partnerships. Atlas Resources also
will serve as each partnership's general drilling contractor and operator and it
will supervise the drilling, completing and operating of the wells to be
drilled.

The address and telephone number of the partnerships and the managing general
partner are 311 Rouser Road, Moon Township, Pennsylvania 15108, (412) 262-2830.

RISK FACTORS
This offering involves numerous risks, including risks related to each
partnership's oil and gas operations, risks related to a partnership investment,
and tax risks. You should carefully consider a number of significant risk
factors inherent in and affecting the business of a partnership and this
offering, including the following.

     o    The drilling operations of the partnership in which you invest involve
          the possibility of a substantial or partial loss of your investment
          because of wells which are productive, but do not produce enough
          revenue to return the investment made and from time to time dry holes.

                                       1


     o    Each partnership's revenues are directly related to its ability to
          market the natural gas and natural gas and oil prices, which are
          volatile and uncertain. If natural gas and oil prices decrease then
          your investment return will decrease.

     o    Unlimited joint and several liability for partnership obligations if
          you choose to invest as an investor general partner until you are
          converted to a limited partner.

     o    Lack of liquidity or a market for the units, necessitates a long-term
          commitment and makes it extremely difficult for you to sell your
          units.

     o    Total reliance on the managing general partner and its affiliates.

     o    Authorization of substantial fees to the managing general partner and
          its affiliates.

     o    Possible allocation of taxable income to investors in excess of their
          cash distributions from a partnership.

     o    Each partnership must receive minimum subscriptions of $2 million to
          close, and the subscription proceeds of all partnerships, in the
          aggregate, including Atlas America Public #15-2005(A) L.P. which
          closed with subscription proceeds of $52,245,720, may not exceed $200
          million. There are no other requirements regarding the size of a
          partnership, and the subscription proceeds of one partnership may be
          substantially more or less than the subscription proceeds of the other
          partnerships. If only the minimum subscriptions are received by a
          partnership, its ability to spread the risks of drilling will be
          greatly reduced as described in "Compensation - Drilling Contracts."

     o    Certain conflicts of interest between the managing general partner and
          you and the other investors and lack of procedures to resolve the
          conflicts.

     o    You and the other investors and the managing general partner will
          share in costs disproportionately to the sharing of revenues.

     o    Currently, the partnerships do not hold any interests in any
          properties or prospects on which the wells will be drilled. Although
          the managing general partner has absolute discretion in determining
          which properties or prospects will be drilled by a partnership, the
          managing general partner intends that Atlas America Public #15-2006(B)
          L.P. will drill the prospects described in "Appendix A - Information
          Regarding Currently Proposed Prospects for Atlas America Public
          #15-2006(B) L.P." These prospects represent a portion of the wells to
          be drilled if the nonbinding targeted maximum subscription proceeds
          described in "Terms of the Offering - Subscription to a Partnership"
          are received, although the managing general partner has the sole
          discretion to sell up to and including all of the remaining units in
          Atlas America Public #15-2006(B) L.P. and not offer and sell any units
          in Atlas America Public #15-2006(C) L.P. If there are adverse events
          with respect to any of the currently proposed prospects, the managing
          general partner will substitute the partnership's prospects. The
          managing general partner also anticipates that it will designate a
          portion of the prospects in Atlas America Public #15-2006(C) L.P., if
          units in that partnership are offered, by a supplement or an amendment
          to the registration statement of which this prospectus is a part.

     o    In each partnership the managing general partner may subordinate a
          portion of its share of that partnership's net production revenues.
          This subordination is not a guaranty by the managing general partner,
          and if the wells in that partnership produce small volumes of natural
          gas and oil and/or natural gas and oil prices decrease, then even with
          subordination your cash flow from the partnership may not return your
          entire investment.

     o    In each partnership monthly cash distributions to its investors may be
          deferred if revenues are used for partnership operations or reserves.

                                       2


TERMS OF THE OFFERING
The offering period for the first partnership will begin on the date of this
prospectus. Each partnership will offer a minimum of 200 units, which is $2
million, and the partnerships, in the aggregate, will offer a maximum of
14,772.6 units which is $147,726,000, which is the remaining portion of the
unsold units from the original $200 million registration. The maximum
subscription proceeds for each partnership will be the lesser of:

     o    the amount of $147,726,000; or

     o    $147,726,000 less the amount of subscriptions sold in the preceding
          partnership.

The targeted subscription proceeds and closing date for each partnership, which
are not binding on the managing general partner, are set forth in a table in
"Terms of the Offering - Subscription to a Partnership." The managing general
partner, however, has the discretion to accept subscriptions for any amount up
to and including the entire amount in Atlas America Public #15-2006(B) L.P. and
not offer and sell any units in Atlas America Public #15-2006(C) L.P.

Units are offered at a subscription price of $10,000 per unit, provided that up
to 5% of the units in each partnership may be sold to certain investors at
discounted prices as described in "Plan of Distribution." All subscriptions must
be paid 100% in cash at the time of subscribing. Your minimum subscription in a
partnership is one unit ($10,000). Larger fractional subscriptions will be
accepted in $1,000 increments, beginning, for example, with $11,000, $12,000,
etc.

You will have the election to purchase units as either an investor general
partner or a limited partner as described in "- Description of Units," below.
Under the partnership agreement no investor, including investor general
partners, may participate in the management of a partnership's business. The
managing general partner will have exclusive management authority for the
partnerships.

Subscription proceeds for each partnership will be held in a separate interest
bearing escrow account at National City Bank of Pennsylvania until receipt of
the minimum subscription proceeds. Each partnership has been formed as a limited
partnership under the Delaware Revised Uniform Limited Partnership Act. In
addition, a partnership may not break escrow as described in "Terms of the
Offering - Partnership Closings and Escrow," unless the partnership is in
receipt of the minimum subscription proceeds after the discounts described in
"Plan of Distribution" and excluding any subscriptions by the managing general
partner or its affiliates. However, on receipt of the minimum subscription
proceeds, the managing general partner on behalf of a partnership may break
escrow, transfer the escrowed funds to a partnership account, and begin its
activities, including drilling. After breaking escrow, additional subscription
proceeds may be paid directly to a partnership account for that partnership and
will continue to earn interest until the offering of units in that partnership
terminates. (See "Terms of the Offering.")

DESCRIPTION OF UNITS
In the partnership being offered at the time you subscribe, you may buy either:

     o    investor general partner units; or

     o    limited partner units.

The partnerships will not issue certificates for their units, but your ownership
of your unit(s) will be recorded on the partnership's books and records. Also,
the type of unit you buy will not affect the allocation of your partnership's
costs, revenues, and cash distributions among you and its other investors. There
are, however, material differences in the federal income tax effects and
liability associated with each type of unit.

INVESTOR GENERAL PARTNER UNITS.

     o    TAX EFFECT. If you invest in a partnership as an investor general
          partner, then your share of the partnership's deduction for intangible
          drilling costs will not be subject to the passive activity limitations
          on losses. For example, if you pay $10,000 for a unit, then generally
          you may deduct not less than 90% of your subscription, $9,000, in the
          year in which you invest, which includes your deduction for intangible
          drilling costs for all of the wells to be drilled by the partnership.
          (See "Federal Income Tax Consequences - Limitations on Passive
          Activity Losses and Credits.")

                                       3


          o    Intangible drilling costs generally means those costs of drilling
               and completing a well that are currently deductible, as compared
               to lease costs which must be recove3red through the depletion
               allowance and costs for equipment in the well which must be
               recovered through depreciation deductions.

     o    LIABILITY. If you invest in a partnership as an investor general
          partner, then you will have unlimited liability regarding the
          partnership's activities. This means that if:

          o    the insurance proceeds from any source;

          o    the managing general partner's indemnification of you and the
               other investor general partners; and

          o    the partnership's assets;

               were not sufficient to satisfy a partnership liability for which
               you and the other investor general partners were also liable
               solely because of your status as general partners of the
               partnership, then the managing general partner would require you
               and the other investor general partners to make additional
               capital contributions to the partnership to satisfy the
               liability. In addition, you and the other investor general
               partners will have joint and several liability, which means
               generally that a person with a claim against the partnership may
               sue all or any one or more of the partnership's general partners,
               including you, for the entire amount of the liability. (See
               "Actions To Be Taken By Managing General Partner To Reduce Risks
               of Additional Payments by Investor General Partners" and
               "Proposed Activities - Insurance.")

     Although past performance is no guarantee of future results, the investor
     general partners in the managing general partner's prior partnerships have
     not had to make any additional capital contributions to their partnerships
     because of their status as investor general partners.

     Your investor general partner units in a partnership will be automatically
     converted by the managing general partner to limited partner units after
     all of the partnership wells have been drilled and completed. The
     conversion will not create any tax liability to you or the other investors.

     Once your units are converted, you will have the lesser liability of a
     limited partner under Delaware law for partnership obligations and
     liabilities arising after the conversion. However, you will continue to
     have the responsibilities of a general partner for partnership liabilities
     and obligations incurred before the effective date of the conversion. For
     example, you might become liable for partnership liabilities in excess of
     your subscription amount during the time the partnership is engaged in
     drilling activities and for environmental claims that arose during drilling
     activities, but were not discovered until after the conversion.

LIMITED PARTNER UNITS.

     o    TAX EFFECT. If you invest in a partnership as a limited partner, then
          your use of your share of the partnership's deduction for intangible
          drilling costs will be limited to offsetting your net passive income
          from "passive" trade or business activities. Passive trade or business
          activities generally include the partnership and other limited partner
          investments, but passive income does not include salaries, dividends
          or interest. This means that you will not be able to deduct your share
          of the partnership's intangible drilling costs in the year in which
          you invest unless you have net passive income from investments other
          than the partnership. However, any portion of your share of the
          partnership's deduction for intangible drilling costs which you cannot
          use in the year in which you invest, because you do not have
          sufficient net passive income in that year, may be carried forward by
          you and used to offset your net passive income from the partnership or
          your other passive activities, if any, in subsequent tax years. (See
          "Federal Income Tax Consequences - Limitations on Passive Activity
          Losses and Credits.")

                                       4


     o    LIABILITY. If you invest in a partnership as a limited partner, then
          you will have limited liability for the partnership's liabilities and
          obligations. This means that you will not be liable for any
          partnership liabilities or obligations beyond the amount of your
          initial investment in the partnership and your share of the
          partnership's undistributed net profits, subject to certain exceptions
          set forth in "Summary of Partnership Agreement - Liability of Limited
          Partners."

USE OF PROCEEDS
Each partnership must receive minimum subscription proceeds of $2 million to
close, and the subscription proceeds of Atlas America Public #15-2006(B) L.P.
and Atlas America Public #15-2006(C) L.P., in the aggregate, may not exceed
$147,726,000. The subscription proceeds of one partnership may be substantially
more or less than the subscription proceeds of the other partnerships and the
managing general partner has the discretion to accept subscriptions for up to
and including the entire amount in Atlas America Public #15-2006(B) L.P. and not
offer and sell any units in Atlas America Public #15-2006(C) L.P. In each
partnership, regardless of whether the partnership receives the minimum or the
maximum subscriptions from you and the other investors:


     o    90% of the subscription proceeds will be used to pay 100% of the
          intangible drilling costs, as defined above in "- Description of
          Units," of drilling and completing the partnership's wells; and

     o    10% of the subscription proceeds will be used to pay a portion of the
          equipment costs of drilling and completing the partnership's wells.

The managing general partner will contribute all of the leases to each
partnership covering the acreage on which that partnership's wells will be
drilled and pay all of the equipment costs of drilling and completing the
partnership's wells that exceed 10% of the partnership's subscription proceeds.
Thus, the managing general partner will pay the majority of each partnership's
equipment costs. The managing general partner also will be charged with 100% of
the organization and offering costs for each partnership. A portion of these
contributions to each partnership will be in the form of payments to itself, its
affiliates and third-parties and the remainder will be in the form of services
related to organizing this offering. The managing general partner will receive a
credit towards its required capital contribution to each partnership for these
payments and services as discussed in "Participation in Costs and Revenues."
(See "Capitalization and Source of Funds and Use of Proceeds" and "Federal
Income Tax Consequences - Intangible Drilling Costs.")

FIVE YEAR-50% SUBORDINATION, PARTICIPATION IN COSTS AND REVENUES, AND
DISTRIBUTIONS
Each partnership will be a separate business entity from the other partnerships,
and you will be a partner only in the partnership in which you invest. You will
have no interest in the business, assets or tax benefits of the other
partnerships unless you also invest in the other partnerships. Thus, your
investment return will depend solely on the operations and success or lack of
success of the particular partnership in which you invest. Each partnership is
structured to provide you and its other investors with cash distributions equal
to a minimum of 10% of capital, based on $10,000 per unit regardless of the
actual subscription price for your units, in each of the first five 12-month
periods beginning with the partnership's first cash distribution from
operations. To help achieve this investment feature of a 10% return of capital
in each of the first five 12-month periods, the managing general partner will
subordinate up to 50% of its share of partnership net production revenues, which
will be up to between 16% and 20% of total partnership net production revenues,
depending on the amount of the managing general partner's capital contribution
to that partnership, during this subordination period. (See "Participation in
Costs and Revenues - Subordination of Portion of the Managing General Partner's
Net Revenue Share.")

Each partnership's 60-month subordination period will begin with the
partnership's first cash distribution from operations to you and its other
investors. Subordination distributions will be determined by debiting or
crediting current period partnership revenues to the managing general partner as
may be necessary to provide the distributions to you and the other investors. At
any time during the subordination period, but not after, the managing general
partner is entitled to an additional share of partnership revenues to recoup
previous subordination distributions to the extent your cash distributions from
the partnership exceed the 10% return of capital described above. The specific
formula is set forth in Section 5.01(b)(4)(a) of the partnership agreement.

                                       5


The following table sets forth the partnership costs and revenues charged and
credited between the managing general partner and you and the other investors
for each partnership after deducting from the partnership's gross revenues the
landowner royalties and any other lease burdens.

(1)    Ninety percent of the subscription proceeds of you and the other
       investors in the partnership in which you subscribe will be used to pay
       100% of the intangible drilling costs incurred by that partnership in
       drilling and completing its wells.
(2)    Ten percent of the subscription proceeds of you and the other investors
       in the partnership in which you subscribe will be used to pay a portion
       of the equipment costs incurred by that partnership in drilling and
       completing its wells. All equipment costs in excess of 10% of the
       partnership's subscription proceeds will be paid by the managing general
       partner. Thus, the managing general partner will pay a majority of each
       partnership's equipment costs. Equipment proceeds, if any, will be
       credited in the same percentage in which the equipment costs were
       charged. Thus, the managing general partner will receive a majority of
       any equipment proceeds.
(3)    These costs will be charged to the parties in the same ratio as the
       related production revenues are being credited. These costs also include
       the plugging and abandonment costs of the wells after their economic
       reserves have been produced and depleted as described in "Participation
       in Costs and Revenues."
(4)    Interest earned on your subscription proceeds before the final closing of
       the partnership to which you subscribed will be credited to your account
       and paid not later than the partnership's first cash distribution from
       operations. After each closing of a partnership, and until the
       subscription proceeds from the closing are invested in the partnership's
       natural gas and oil operations, any interest income from temporary
       investments will be allocated pro rata to the investors providing the
       subscription proceeds. All other interest income, including interest
       earned on the deposit of operating revenues, will be credited as natural
       gas and oil production revenues are credited.
(5)    The managing general partner and the investors in a partnership will
       share in all of that partnership's other revenues in the same percentage
       as their respective capital contributions bears to the total partnership
       capital contributions, except that the managing general partner will
       receive an additional 7% of the partnership revenues. However, the
       managing general partner's total revenue share may not exceed 40% of
       partnership revenues.
(6)    The actual allocation of partnership revenues between the managing
       general partner and the investors will vary from the allocation described
       in (5) above if a portion of the managing general partner's partnership
       net production revenues is subordinated as described above.

The managing general partner will review each partnership's accounts at least
monthly to determine whether cash distributions are appropriate and the amount
to be distributed, if any. The partnership in which you invest will distribute
funds to you and its other investors that the managing general partner does not
believe are necessary for the partnership to retain. (See "Participation in
Costs and Revenues.")

COMPENSATION
The items of compensation paid to the managing general partner and its
affiliates from each partnership are as follows:

                                       6


     o    The managing general partner will receive a share of each
          partnership's revenues. The managing general partner's revenue share
          will be in the same percentage as its capital contribution bears to
          that partnership's total capital contributions plus an additional 7%
          of partnership revenues, but not to exceed a total of 40% of
          partnership revenues, regardless of the amount of the managing general
          partner's capital contribution, subject to the managing general
          partner's subordination obligation.

     o    The managing general partner will receive a credit to its capital
          account equal to the cost of the leases or the fair market value of
          the leases if the managing general partner has reason to believe that
          cost is materially more than the fair market value.

     o    Each partnership will enter into the drilling and operating agreement
          with the managing general partner to drill and complete the
          partnership wells at cost plus a nonaccountable, fixed payment
          reimbursement of $15,000 from the investors to the managing general
          partner for its general and administrative overhead plus 15%.

     o    When a partnership's wells begin producing the managing general
          partner, as operator of the wells, will receive:

          o    reimbursement at actual cost for all direct expenses incurred on
               behalf of the partnership; and

          o    well supervision fees for operating and maintaining the wells
               during producing operations at a competitive rate.

     o    The managing general partner will receive gathering fees at
          competitive rates.

     o    Subject to certain exceptions described in "Plan of Distribution,"
          Anthem Securities, Inc., the dealer-manager and an affiliate of the
          managing general partner, which is sometimes referred to in this
          prospectus as "Anthem Securities," will receive on each unit sold to
          an investor a 2.5% dealer-manager fee, a 7% sales commission, a .5%
          accountable reimbursement for permissible non-cash compensation, and
          up to a .5% reimbursement of the selling agents' bona fide due
          diligence expenses.

     o    The managing general partner or an affiliate will have the right to
          charge a competitive rate of interest on any loan it may make to or on
          behalf of a partnership. If the managing general partner provides
          equipment, supplies, and other services to a partnership, then it may
          do so at competitive industry rates.

     o    The managing general partner and its affiliates will receive a
          nonaccountable, fixed payment reimbursement for their administrative
          costs, which has been determined by the managing general partner to be
          $75 per well per month. The managing general partner may not increase
          this fee during the term of the partnership.

                                  RISK FACTORS

An investment in a partnership involves a high degree of risk and is suitable
only if you have substantial financial means and no need of liquidity in your
investment.

RISKS RELATED TO THE PARTNERSHIPS' OIL AND GAS OPERATIONS
NO GUARANTEE OF RETURN OF INVESTMENT OR RATE OF RETURN ON INVESTMENT BECAUSE OF
SPECULATIVE NATURE OF DRILLING NATURAL GAS AND OIL WELLS. Natural gas and oil
exploration is an inherently speculative activity. Before the drilling of a well
the managing general partner cannot predict with absolute certainty:

     o    the volume of natural gas and oil recoverable from the well; or

     o    the time it will take to recover the natural gas and oil.

You may not recover all of your investment in a partnership, or if you do
recover your investment in a partnership you may not receive a rate of return on
your investment which is competitive with other types of investment. You will be
able to recover your investment only through distributions of the partnership's
net proceeds from the sale of its natural gas and oil from productive wells. The
quantity of natural gas and oil in a well, which is referred to as its reserves,
decreases over time as the natural gas and oil is produced until the well is no
longer economical to operate. All of these distributions to you will be
considered a return of capital until you have received 100% of your investment.
This means that you are not receiving a return on your investment in a
partnership, excluding tax benefits, until your total cash distributions from
the partnership exceed 100% of your investment. (See "Prior Activities.")


BECAUSE SOME WELLS MAY NOT RETURN THEIR DRILLING AND COMPLETION COSTS, IT MAY
TAKE MANY YEARS TO RETURN YOUR INVESTMENT IN CASH, IF EVER. Even if a well is
completed in a partnership and produces natural gas and oil in commercial
quantities, it may not produce enough natural gas and oil to pay for the costs
of drilling and completing the well, even if tax benefits are considered. For
example, the managing general partner has formed 51 partnerships since 1985,
however, 36 of the 51 partnerships have not yet returned to the investor 100% of
his capital contributions without taking tax savings into account. Thus, it may
take many years to return your investment in cash, if ever. The partnerships'
primary drilling areas are located in the most active drilling areas in the
Appalachian Basin. As a result, many of the leases which will be drilled by a
partnership are in areas that have already been partially depleted or drained by
earlier offset drilling. This may reduce a partnership's ability to find
economically recoverable quantities of natural gas in those areas. (See "Prior
Activities.")


NONPRODUCTIVE WELLS MAY BE DRILLED EVEN THOUGH THE PARTNERSHIPS' OPERATIONS ARE
PRIMARILY LIMITED TO DEVELOPMENT DRILLING. Each partnership may drill some
development wells which are nonproductive, which is referred to as a "dry hole,"
and must be plugged and abandoned. If one or more of a partnership's wells are
nonproductive, then the partnership's productive wells may not produce enough
revenues to offset the loss of investment in the nonproductive wells. (See
"Prior Activities.")

PARTNERSHIP DISTRIBUTIONS MAY BE REDUCED IF THERE IS A DECREASE IN THE PRICE OF
NATURAL GAS AND OIL. The prices at which a partnership's natural gas and oil
will be sold are uncertain and, as discussed in "- Adverse Events in Marketing a
Partnership's Natural Gas Could Reduce Partnership Distributions," the
partnerships are not guaranteed a specific natural gas price for the sale of
their natural gas production. Changes in natural gas and oil prices will have a
significant impact on a partnership's cash flow and the value of its reserves.
Historically, natural gas and oil prices have been volatile and it is likely
that they will continue to be volatile in the future. Prices for natural gas and
oil will depend on supply and demand factors largely beyond the control of the
partnerships and prices may fluctuate widely in response to relatively minor
changes in the supply of and demand for natural gas or oil, market uncertainty
and a variety of additional factors that are beyond a partnership's control, as
described in "Competition, Markets and Regulations -- Competition and Markets."
These factors make it extremely difficult to predict natural gas and oil price
movements with any certainty.

If natural gas and oil prices decrease in the future, then your partnership
distributions will decrease accordingly. Also, natural gas and oil prices may
decrease during the first years of production from your partnership's wells
which is when the wells typically achieve their greatest level of production.
This would have a greater adverse effect on your partnership distributions than
price decreases in later years when the wells have a lower level of production.
Also, your return level will decrease during the term of the partnership, even
if there are rising natural gas prices, because of declining production volumes
from the wells. (See "Appendix A - Information Regarding Currently Proposed
Prospects for Atlas America Public #15-2006(B) L.P." for a discussion of flush
production and "Proposed Activities - Sale of Natural Gas and Oil Production.")


                                       8


ADVERSE EVENTS IN MARKETING A PARTNERSHIP'S NATURAL GAS COULD REDUCE PARTNERSHIP
DISTRIBUTIONS. In addition to the risk of decreased natural gas and oil prices
described above, there are risks associated with marketing natural gas which
could reduce a partnership's distributions to you and its other investors. These
risks are set forth below.

     o    Competition from other natural gas producers and marketers in the
          Appalachian Basin as well as competition from alternative energy
          sources may make it more difficult to market each partnership's
          natural gas.

     o    The majority of each partnership's natural gas production and that of
          the managing general partner will be sold to a limited number of
          different natural gas purchasers as described in "Proposed Activities
          - Sale of Natural Gas and Oil Production." As set forth in "Appendix A
          - Information Regarding Currently Proposed Prospects for Atlas America
          Public #15-2006(B) L.P.," the managing general partner has identified
          three primary areas where it intends to drill each partnership's
          wells. Generally, the managing general partner anticipates that
          initially each partnership's natural gas production in each of the
          three primary areas will be sold to a different purchaser. Thus, each
          partnership will depend on a limited number of natural gas purchasers.
          If a partnership loses a natural gas purchaser in a given area, the
          partnership may be unable to locate a new natural gas purchaser in the
          area which will buy its natural gas on as favorable terms as the
          initial purchaser.

          Although one of the natural gas purchasers has a 10-year agreement,
          which began on April 1, 1999, to buy all of the managing general
          partner's and its affiliates' natural gas production, there are
          various exceptions to its obligation to buy the natural gas. The most
          significant exception for each partnership includes natural gas
          produced from the Fayette County, Pennsylvania area, which is where
          the managing general partner anticipates that the majority of each
          partnership's prospects will be situated. The majority of the natural
          gas produced from the Fayette County area, by each partnership
          initially will be sold to one purchaser under a natural gas contract
          described in "Proposed Activities - Sale of Natural Gas and Oil
          Production," which ends March 31, 2007. Of the remaining two primary
          areas, there will be a different natural gas purchaser in each area
          and natural gas produced from only one of those areas will be sold
          under the 10-year agreement referred to above. Also, all of these
          natural gas purchase contracts provide that the price paid by the
          natural gas purchaser may be adjusted upward or downward in accordance
          with the spot market price and market conditions as described in
          "Proposed Activities - Sale of Natural Gas and Oil Production." Thus,
          neither of the partnerships will be guaranteed a specific natural gas
          price, other than through hedging or forward sales transactions
          through the natural gas purchasers (which is not considered hedging
          for accounting purposes), and the price a partnership receives for the
          sale of its natural gas may decrease in the future because of market
          conditions. Although hedging and forward sales transactions provide
          the partnerships some protection against falling natural gas prices,
          those arrangements also could reduce the potential benefits of price
          increases if, at the time the natural gas is to be delivered, the spot
          market natural gas price is higher than the price paid under the
          hedging arrangements or forward sales transactions.


     o    There is a credit risk associated with a natural gas purchaser's
          ability to pay. Each partnership may not be paid, or may experience
          delays in receiving payment, for natural gas that has already been
          delivered. In accordance with industry practice, a partnership
          typically will deliver natural gas to a purchaser for a period of up
          to 60 to 90 days before it receives payment. Thus, it is possible that
          the partnership may not be paid for natural gas that already has been
          delivered if the natural gas purchaser fails to pay for any reason,
          including bankruptcy. This ongoing credit risk also may delay or
          interrupt the sale of the partnership's natural gas or its negotiation
          of different terms and arrangements for selling its natural gas to
          other purchasers. Finally, this credit risk may reduce the price
          benefit derived by the partnerships from the managing general
          partner's natural gas hedging as described in "Proposed Activities -
          Sale of Natural Gas and Oil Production - Natural Gas Contracts," since
          the majority of the managing general partner's natural gas hedges are
          implemented through the natural gas purchasers.

                                       9


     o    Partnership revenues will decrease the farther the natural gas is
          transported because of increased transportation costs.

     o    Production from wells drilled in certain areas, such as the wells in
          Crawford County, Pennsylvania and to a lesser extent, Fayette County,
          Pennsylvania and Anderson, Campbell, Morgan, Scott and Roane Counties,
          Tennessee, may be delayed until construction of the necessary
          gathering lines and production facilities is completed. (See "Proposed
          Activities - Sale of Natural Gas and Oil Production - Gathering of
          Natural Gas.")

     o    The managing general partner anticipates that it will use the
          gathering system owned by Atlas Pipeline Partners for the majority of
          the natural gas as described in "Proposed Activities - Sale of Natural
          Gas and Oil Production - Gathering of Natural Gas." Atlas Pipeline
          Partners GP, LLC, a wholly-owned subsidiary of Atlas Pipeline
          Holdings, L.P., an affiliate of Atlas America, Inc., which is
          sometimes referred to in this prospectus as "Atlas America" and is the
          indirect parent company of the managing general partner, controls and
          manages the gathering system for Atlas Pipeline Partners. (See
          "Management - Organizational Diagram and Securities Ownership of
          Beneficial Owners.") Atlas Pipeline Holdings, L.P., as a public
          company, may be more susceptible to a change of control from Atlas
          America's affiliates to independent third-parties. Also, if Atlas
          Pipeline Partners GP, LLC were removed as general partner of Atlas
          Pipeline Partners without cause and without its consent, this could
          increase the amount of gathering fees required to be paid by the
          partnerships for natural gas transported through Atlas Pipeline
          Partners' gathering system since Atlas Pipeline Partners GP, LLC would
          no longer receive revenues from Atlas Pipeline Partners, but Atlas
          America and its affiliates would be obligated to pay the difference
          between the amount in the master natural gas gathering agreement and
          the amount paid by the partnership other than with respect to new
          wells drilled after the removal. Thus, the managing general partner
          and its affiliates may have an incentive to increase the gathering
          fees. Any increase in the gathering fees that your partnership pays
          would reduce your cash distributions from the partnership.

POSSIBLE LEASEHOLD DEFECTS. There may be defects in a partnership's title to its
leases. Although the managing general partner will obtain a favorable formal
title opinion for the leases before each well is drilled, it will not obtain a
division order title opinion after the well is completed. A partnership may
experience losses from title defects which arose during drilling that would have
been disclosed by a division order title opinion, such as liens that may arise
during drilling or transfers made after drilling begins. Also, the managing
general partner may use its own judgment in waiving title requirements and will
not be liable for any failure of title of leases transferred to the partnership.
(See "Proposed Activities - Title to Properties.")

TRANSFER OF THE LEASES WILL NOT BE MADE UNTIL WELL IS COMPLETED. Because the
leases will not be transferred from the managing general partner to a
partnership until after the wells are drilled and completed, the transfer could
be set aside by a creditor of the managing general partner, or the trustee in
the event of the voluntary or involuntary bankruptcy of the managing general
partner, if it were determined that the managing general partner received less
than a reasonably equivalent value for the leases. In this event, the leases and
the wells would revert to the creditors or trustee, and the partnership would
either recover nothing or only the amount paid for the leases and the cost of
drilling the wells. Assigning the leases to a partnership after the wells are
drilled and completed, however, will not affect the availability of the tax
deductions for intangible drilling costs since the partnership will have an
economic interest in the wells under the drilling and operating agreement before
the wells are drilled. (See "Proposed Activities - Title to Properties.")

PARTICIPATION WITH THIRD-PARTIES IN DRILLING WELLS MAY REQUIRE THE PARTNERSHIPS
TO PAY ADDITIONAL COSTS. Third-parties will participate with each partnership in
drilling some of the wells. Financial risks exist when the cost of drilling,
equipping, completing, and operating wells is shared by more than one person. If
a partnership pays its share of the costs, but another interest owner does not
pay its share of the costs, then the partnership would have to pay the costs of
the defaulting party. In this event, the partnership would receive the
defaulting party's revenues from the well, if any, under penalty arrangements
set forth in the operating agreement, which may, or may not, cover all of the
additional costs paid by the partnership.

                                       10


If the managing general partner is not the actual operator of the well, then
there is a risk that the managing general partner cannot supervise the
third-party operator closely enough. For example, decisions related to the
following would be made by the third-party operator and may not be in the best
interests of the partnerships and you and the other investors:

     o    how the well is operated;

     o    expenditures related to the well; and

     o    possibly the marketing of the natural gas and oil production.

Further, the third-party operator may have financial difficulties and fail to
pay for materials or services on the wells it drills or operates, which would
cause the partnership to incur extra costs in discharging materialmen's and
workmen's liens. The managing general partner may not be the operator of the
well if the partnership owns less than a 50% working interest in the well, or if
the managing general partner acquired the working interest in the well from a
third-party which required that the third-party be named operator as one of the
terms of the acquisition.

RISKS RELATED TO AN INVESTMENT IN A PARTNERSHIP
IF YOU CHOOSE TO INVEST AS A GENERAL PARTNER, THEN YOU HAVE GREATER RISK THAN A
LIMITED PARTNER. If you invest in a partnership as an investor general partner
for the tax benefits instead of as a limited partner, then under Delaware law
you will have unlimited liability for your partnership's activities until you
are converted to limited partner status, subject to certain exceptions described
in "Actions To Be Taken by Managing General Partner To Reduce Risks of
Additional Payments By Investor General Partners - Conversion of Investor
General Partner Units to Limited Partner Units." This could result in you being
required to make payments, in addition to your original investment, in amounts
that are impossible to predict because of their uncertain nature. Under the
terms of the partnership agreement, if you are an investor general partner you
agree to pay only your proportionate share of your partnership's obligations and
liabilities. This agreement, however, does not eliminate your liability to
third-parties if another investor general partner does not pay his proportionate
share of your partnership's obligations and liabilities.

Also, each partnership will own less than 100% of the working interest in some
of its wells. If a court holds you and the other third-party working interest
owners of the well liable for the development and operation of a well and the
third-party working interest owners do not pay their proportionate share of the
costs and liabilities associated with the well, then the partnership and you and
the other investor general partners also would be liable for those costs and
liabilities.

As an investor general partner you may become subject to the following:

     o    contract liability, which is not covered by insurance;

     o    liability for pollution, abuses of the environment, and other
          environmental damages such as the release of toxic gas, spills or
          uncontrollable flows of natural gas, oil or fluids, against which the
          managing general partner cannot insure because coverage is not
          available or against which it may elect not to insure because of high
          premium costs or other reasons; and

     o    liability for drilling hazards which result in property damage,
          personal injury, or death to third-parties in amounts greater than the
          insurance coverage. The drilling hazards include, but are not limited
          to well blowouts, fires, and explosions.

If your partnership's insurance proceeds and assets, the managing general
partner's indemnification of you and the other investor general partners, and
the liability coverage provided by major subcontractors were not sufficient to
satisfy the liability, then the managing general partner would call for
additional funds from you and the other investor general partners to satisfy the
liability. (See "Actions To Be Taken By Managing General Partner To Reduce Risks
of Additional Payments by Investor General Partners.")

                                       11


THE MANAGING GENERAL PARTNER MAY NOT MEET ITS CAPITAL CONTRIBUTIONS,
INDEMNIFICATION AND PURCHASE OBLIGATIONS IF ITS LIQUID NET WORTH IS NOT
SUFFICIENT. The managing general partner has made commitments to you and the
other investors in each partnership regarding the following:

     o    the payment of organization and offering costs and the majority of
          equipment costs;

     o    indemnification of the investor general partners for liabilities in
          excess of their pro rata share of partnership assets and insurance
          proceeds; and

     o    purchasing units presented by an investor, although this may be
          suspended if the managing general partner determines, in its sole
          discretion, that it does not have the necessary cash flow or cannot
          borrow funds for this purpose on reasonable terms.

A significant financial reversal for the managing general partner could
adversely affect its ability to honor these obligations.

The managing general partner's net worth is based primarily on the estimated
value of its producing natural gas properties and is not available in cash
without borrowings or a sale of the properties. Also, if natural gas prices
decrease, then the estimated value of the properties and the managing general
partner's net worth will be reduced. Further, price decreases will reduce the
managing general partner's revenues, and may make some reserves uneconomic to
produce. This would reduce the managing general partner's reserves and cash
flow, and could cause the lenders of the managing general partner and its
affiliates to reduce the borrowing base for the managing general partner and its
affiliates. Also, because the majority of the managing general partner's proved
reserves are currently natural gas reserves, the managing general partner's net
worth is more susceptible to movements in natural gas prices than in oil prices.

The managing general partner's net worth may not be sufficient, either currently
or in the future, to meet its financial commitments under the partnership
agreement. These risks are increased because the managing general partner has
made similar financial commitments in most of its other partnerships and will
make this same commitment in future partnerships. See "Financial Information
Concerning the Managing General Partner and Atlas America Public #15-2006(B)
L.P."

AN INVESTMENT IN A PARTNERSHIP MUST BE FOR THE LONG-TERM BECAUSE THE UNITS ARE
ILLIQUID AND NOT READILY TRANSFERABLE. If you invest in a partnership, then you
must assume the risks of an illiquid investment. The transferability of the
units is limited by the securities laws, the tax laws, and the partnership
agreement. The units generally cannot be liquidated since there is not a readily
available market for the sale of the units. Further, the partnerships do not
intend to list the units on any exchange.

Also, a sale of your units could create adverse tax and economic consequences
for you. The sale or exchange of all or part of your units held for more than 12
months generally will result in a recognition of long-term capital gain or loss.
However, previous deductions for depreciation, depletion and IDCs may be
recaptured as ordinary income rather than capital gain regardless of how long
you have owned the units. If the units are held for 12 months or less, then the
gain or loss generally will be short-term gain or loss. Your pro rata share of a
partnership's liabilities, if any, as of the date of the sale or exchange must
be included in the amount realized by you. Thus, the gain recognized by you may
result in a tax liability greater than the cash proceeds, if any, received by
you from the disposition. (See "Federal Income Tax Consequences - Disposition of
Units" and "Presentment Feature.")

SPREADING THE RISKS OF DRILLING AMONG A NUMBER OF WELLS WILL BE REDUCED IF LESS
THAN THE MAXIMUM SUBSCRIPTION PROCEEDS ARE RECEIVED AND FEWER WELLS ARE DRILLED.
Each partnership must receive minimum subscription proceeds of $2 million to
close, and the subscription proceeds of both of the partnerships, in the
aggregate, may not exceed $147,726,000, which is 20,000 units, less the units
sold in Atlas America Public #15-2005(A) L.P. assuming all of the remaining
unsold units are sold at $10,000 per unit. There are no other requirements
regarding the size of a partnership other than the nonbinding targeted maximum
amounts described in "Terms of the Offering - Subscription to a Partnership." In
this regard, the targeted maximum subscription proceeds in Atlas America Public
#15-2006(B) L.P. are $125 million, and the targeted maximum subscription
proceeds in Atlas America Public #15-2006(C) L.P. are $22,726,000. Thus, the
managing general partner intends that the subscription proceeds of Atlas America
Public #15-2006(C) L.P. will be substantially less than the targeted
subscription proceeds of $125 million for Atlas America Public #15-2006(B) L.P.
A partnership with a smaller amount of subscription proceeds will drill fewer
wells which decreases the partnership's ability to spread the risks of drilling.
For example, the managing general partner anticipates that a partnership will
drill approximately eight net wells if the minimum subscriptions of $2 million
are received, which is compared with approximately 588.5 net wells if
subscription proceeds of $147,726,000 are received by a partnership. A gross
well is a well in which a partnership owns a working interest. This is compared
with a net well which is the sum of the fractional working interests owned in
the gross wells. For example, a 50% working interest owned in three wells is
three gross wells, but 1.5 net wells.

                                       12


On the other hand, to the extent more than the minimum subscriptions are
received by a partnership and the number of wells drilled increases, the
partnership's overall investment return may decrease if the managing general
partner is unable to find enough suitable wells to be drilled. See "Proposed
Activities - Acquisition of Leases.") Also, in a large partnership greater
demands will be placed on the managing general partner's management
capabilities. In this regard, the managing general partner has the discretion to
accept subscriptions for any amount, up to and including the entire $147,726,000
in Atlas America Public #15-2006(B) L.P. and it may not offer and sell any units
in Atlas America Public #15-2006(C) L.P.

Also, the cost of drilling and completing a well is often uncertain and there
may be cost overruns in drilling and completing the wells because the wells will
not be drilled and completed on a turnkey basis for a fixed price, which would
shift the risk of loss to the managing general partner as drilling contractor.
The majority of the equipment costs of each partnership's wells will be paid by
the managing general partner. However, all of the intangible drilling costs of a
partnership's wells will be charged to you and the other investors in that
partnership. If a partnership incurs a cost overrun for the intangible drilling
costs of a well or wells, then the managing general partner anticipates that it
would use the partnership's subscription proceeds, if available, to pay the cost
overrun or advance the necessary funds to the partnership. Using subscription
proceeds to pay cost overruns will result in a partnership drilling fewer wells.

INCREASES IN THE COSTS OF THE WELLS MAY ADVERSELY AFFECT YOUR RETURN. The
increase in natural gas and oil prices over the last several years has increased
the demand for drilling rigs and other related equipment, and the costs of
drilling and completing natural gas and oil wells also have increased.
Additionally, the managing general partner and its affiliates have experienced
an increase in the cost of tubular steel used in drilling the wells as a result
of rising steel prices. Because each partnership's wells will be drilled on a
cost plus basis as described in "Compensation - Drilling Contracts," these
increased costs will increase the cost to drill and complete each partnership's
wells. Also, the reduced availability of drilling rigs and other related
equipment may make it more difficult to drill a partnership's wells in a timely
manner or to comply with the prepaid intangible drilling costs rules discussed
in "Federal Income Tax Consequences - Drilling Contracts."

THE PARTNERSHIPS DO NOT OWN ANY PROSPECTS, THE MANAGING GENERAL PARTNER HAS
COMPLETE DISCRETION TO SELECT WHICH PROSPECTS ARE ACQUIRED BY A PARTNERSHIP, AND
THE POSSIBLE LACK OF INFORMATION FOR A MAJORITY OF THE PROSPECTS DECREASES YOUR
ABILITY TO EVALUATE THE FEASIBILITY OF A PARTNERSHIP. The partnerships do not
currently hold any interests in any prospects on which the wells will be
drilled, and the managing general partner has absolute discretion in determining
which prospects will be acquired to be drilled. The managing general partner has
identified in "Proposed Activities" the general areas where each partnership
will drill wells and the managing general partner intends that Atlas America
Public #15-2006(B) L.P. will drill the prospects described in "Appendix A -
Information Regarding Currently Proposed Prospects for Atlas America Public
#15-2006(B) L.P." These prospects represent the wells currently proposed to be
drilled only if a portion of the targeted nonbinding amount of subscription
proceeds is received by Atlas America Public #15-2006(B) L.P. as described in
"Terms of the Offering - Subscription to a Partnership."

If there are adverse events with respect to any of the currently proposed
prospects, the managing general partner will substitute the partnership's
prospects. The managing general partner also anticipates that it will designate
a portion of the prospects in Atlas America Public #15-2006(C) L.P., if units
are offered in that partnership, by a supplement or an amendment to the
registration statement of which this prospectus is a part. With respect to the
identified prospects for a partnership, the managing general partner has the
right on behalf of the partnership to:

     o    substitute prospects;

                                       13


     o    take a lesser working interest in the prospects;

     o    drill in other areas; or

     o    do any combination of the foregoing.

Thus, you do not have any geological or production information to evaluate any
additional and/or substituted prospects and wells. Also, if the subscription
proceeds received by a partnership are insufficient to drill all of the
identified prospects, then the managing general partner will choose those
prospects which it believes are most suitable for the partnership. You must rely
entirely on the managing general partner to select the prospects and wells for a
partnership.

In addition, the partnerships do not have the right of first refusal in the
selection of prospects from the inventory of the managing general partner and
its affiliates, and they may sell their prospects to other partnerships,
companies, joint ventures, or other persons at any time.

DRILLING PROSPECTS IN ONE AREA MAY INCREASE RISK. If multiple wells are drilled
in one area at approximately the same time, then there is a greater risk that
two or more of the wells will be marginal or nonproductive since the managing
general partner will not be using the drilling results of one or more of those
wells to decide whether or not to continue drilling prospects in that area or to
substitute other prospects in other areas. This is compared with the situation
in which the managing general partner drills one well, and then assesses the
drilling results before it decides to drill a second well in the same area or to
substitute a different prospect in another area.

This risk is further increased with respect to wells for which the drilling and
completing costs are prepaid in one year, and the drilling of the wells must
begin within the first 90 days of the immediately following year under the tax
laws associated with deducting the intangible drilling costs of the prepaid
wells in the year in which the prepayment is made, rather than the year in which
the wells are drilled. For example, potential bad weather conditions during the
first 90 days of the following year could delay beginning the drilling of one or
more prepaid wells beyond the 90 day time limit under the tax laws. This would
have a greater adverse effect on a partnership's deduction for prepaid
intangible drilling costs if the managing general partner is required to begin
drilling many wells at the same time, rather than only a few wells. Also, "frost
laws" prohibit drilling rigs and other heavy equipment from using certain roads
during the winter, which may delay beginning the drilling of the wells within
the 90 day time limit under the tax laws. In addition, there could be shortages
of drilling rigs, equipment, supplies and personnel during this time period.
(See "Federal Income Tax Consequences - Drilling Contracts" regarding prepaid
wells and the 90 day time constraint.)

LACK OF PRODUCTION INFORMATION INCREASES YOUR RISK AND DECREASES YOUR ABILITY TO
EVALUATE THE FEASIBILITY OF A PARTNERSHIP'S DRILLING PROGRAM. Production
information from surrounding wells in the area is an important indicator in
evaluating the economic potential of a well proposed to be drilled. However, the
data set forth in "Appendix A - Information Concerning Currently Proposed Wells
for Atlas America Public #15-2006(B) L.P." for the proposed wells in
Pennsylvania may not show all of the surrounding wells drilled and/or production
from those wells because there was a third-party operator and the Pennsylvania
Department of Environmental Resources keeps production data confidential for the
first five years from the time a well starts producing. If the managing general
partner is the operator and no production data is shown, it is because of the
following:

     o    the wells are not yet completed;

     o    the wells are not on-line to sell production; or

     o    the wells have been producing for only a short period of time.

This lack of production information from surrounding wells for the majority of
the wells to be drilled by a partnership as shown in "Appendix A -- Information
Regarding Currently Proposed Prospects for Atlas America Public #15-2006(B)
L.P.," results in greater uncertainty to you and the other investors.

                                       14


THE PARTNERSHIPS IN THIS PROGRAM AND OTHER PARTNERSHIPS SPONSORED BY THE
MANAGING GENERAL PARTNER MAY COMPETE WITH EACH OTHER FOR PROSPECTS, EQUIPMENT,
CONTRACTORS, AND PERSONNEL. One or more partnerships in this program or other
partnerships sponsored by the managing general partner may have unexpended
capital funds at the same time. Thus, these partnerships may compete for
suitable prospects and the availability of equipment, contractors, and the
managing general partner's personnel. For example, a partnership previously
organized by the managing general partner may still be acquiring prospects to
drill when the partnerships in this program are attempting to acquire prospects.
This may make it more difficult to complete the prospect acquisition and
drilling activities for the partnerships in this program and may make each
partnership less profitable.

MANAGING GENERAL PARTNER'S SUBORDINATION IS NOT A GUARANTEE OF THE RETURN OF ANY
OF YOUR INVESTMENT. If your cash distributions from the partnership in which you
invest are less than a 10% return of capital for each of the first five 12-month
periods beginning with the partnership's first cash distribution from
operations, then the managing general partner has agreed to subordinate a
portion of its share of the partnership's net production revenues. However, if
the wells produce only small natural gas and oil volumes, and/or natural gas and
oil prices decrease, then even with subordination you may not receive the 10%
return of capital for each of the first five years as described above, or a
return of your capital during the term of the partnership. Also, at any time
during the subordination period the managing general partner is entitled to an
additional share of partnership revenues to recoup previous subordination
distributions to the extent your cash distributions from the partnership exceed
the 10% return of capital described above. (See "Participation in Costs and
Revenues - Subordination of Portion of the Managing General Partner's Net
Revenue Share.")


BORROWINGS BY THE MANAGING GENERAL PARTNER COULD REDUCE FUNDS AVAILABLE FOR ITS
SUBORDINATION OBLIGATION. With respect to each partnership, the managing general
partner has or will pledge either its partnership interest and/or an undivided
interest in the partnership's assets equal to or less than its revenue interest,
which will range from 32% to 40%, depending on the amount of its capital
contribution, to secure borrowings for its and its affiliates' general purposes.
(See "Participation in Costs and Revenues" and "Conflicts of Interest -
Conflicts Regarding Managing General Partner Withdrawing or Assigning an
Interest.") Under agreements previously entered into as described in
"Management's Discussion and Analysis of Financial Condition, Results of
Operations, Liquidity and Capital Resources," the managing general partner's
lenders have required a first lien on the managing general partner's interest in
the natural gas and oil properties and other assets of each partnership, and the
lenders will have priority over the managing general partner's subordination
obligation under the partnership agreement for each partnership. Thus, if there
was a default to the lenders under this pledge arrangement, or if there was a
default by an affiliate of the managing general partner under a loan secured by
this pledge arrangement, the amount of each partnership's net production
revenues available to the managing general partner for its subordination
obligation to you and the other investors would be reduced or eliminated. Also,
under certain circumstances, if the managing general partner made a
subordination distribution to you and the other investors after a default to its
lenders, then the lenders may be able to recoup that subordination distribution
from you and the other investors.


COMPENSATION AND FEES TO THE MANAGING GENERAL PARTNER REGARDLESS OF SUCCESS OF A
PARTNERSHIP'S ACTIVITIES WILL REDUCE CASH DISTRIBUTIONS. The managing general
partner and its affiliates will profit from their services in drilling,
completing, and operating each partnership's wells, and will receive the other
fees and reimbursement of direct costs described in "Compensation," regardless
of the success of the partnership's wells. These fees and direct costs will
reduce the amount of cash distributions to you and the other investors. The
amount of the fees is subject to the complete discretion of the managing general
partner, other than the fees must not exceed competitive fees charged by
unaffiliated third-parties in the same geographic area engaged in similar
businesses and they must comply with any other restrictions set forth in
"Compensation." With respect to direct costs, the managing general partner has
sole discretion on behalf of each partnership to select the provider of the
services or goods and the provider's compensation as discussed in
"Compensation."

THE INTENDED MONTHLY DISTRIBUTIONS TO INVESTORS MAY BE REDUCED OR DELAYED. Cash
distributions to you and the other investors may not be paid each month.
Distributions may be reduced or deferred, in the discretion of the managing
general partner, to the extent a partnership's revenues are used for any of the
following:


     o    compensation and fees to the managing general partner as described
          above in "- Compensation and Fees to the Managing General Partner
          Regardless of Success of a Partnership's Activities Will Reduce Cash
          Distributions";


                                       15


     o    repayment of borrowings;

     o    cost overruns;

     o    remedial work to improve a well's producing capability;

     o    direct costs and general and administrative expenses of the
          partnership;

     o    reserves, including a reserve for the estimated costs of eventually
          plugging and abandoning the wells; or

     o    indemnification of the managing general partner and its affiliates by
          the partnership for losses or liabilities incurred in connection with
          the partnership's activities. (See "Participation in Costs and
          Revenues - Distributions.")

THERE ARE CONFLICTS OF INTEREST BETWEEN THE MANAGING GENERAL PARTNER AND THE
INVESTORS. There are conflicts of interest between you and the managing general
partner and its affiliates. These conflicts of interest, which are not otherwise
discussed in this "Risk Factors" section, include the following:

     o    the managing general partner has determined the compensation and
          reimbursement that it and its affiliates will receive in connection
          with the partnerships without any unaffiliated third-party dealing at
          arms' length on behalf of the investors;

     o    the managing general partner must monitor and enforce, on behalf of
          the partnerships, its own compliance with the drilling and operating
          agreement and the partnership agreement and the compliance of it and
          its affiliate, Atlas Pipeline Partners, with the gas gathering
          agreement;

     o    because the managing general partner will receive a percentage of
          revenues greater than the percentage of costs that it pays, there may
          be a conflict of interest concerning which wells will be drilled based
          on the wells' risk and profit potential;

     o    the allocation of all intangible drilling costs to you and the other
          investors and the majority of the equipment costs to the managing
          general partner may create a conflict of interest concerning whether
          to complete a well;

     o    if the managing general partner, as tax matters partner, represents a
          partnership before the IRS, potential conflicts include whether or not
          to expend partnership funds to contest a proposed adjustment by the
          IRS, if any, to the amount of your deduction for intangible drilling
          costs, or the credit to the managing general partner's capital account
          for contributing the leases to the partnership;

     o    which wells will be drilled by the managing general partner's and its
          affiliates' other affiliated partnerships or third-party programs in
          which they serve as driller/operator and which wells will be drilled
          by the partnerships in this program, and the terms on which the
          partnerships' leases will be acquired;

     o    the terms on which the managing general partner or affiliated limited
          partnerships may purchase producing wells from each partnership;

     o    the possible purchase of units by the managing general partner, its
          officers, directors, and affiliates for a reduced price, which would
          dilute the voting rights of you and the other investors on certain
          matters;

     o    the representation of the managing general partner and each
          partnership by the same legal counsel;

     o    the right of Atlas Pipeline Partners to determine the order of
          priority for constructing gathering lines;

                                       16


     o    the benefits to Atlas Pipeline Partners of the partnerships drilling
          wells that will connect to the gathering system owned by Atlas
          Pipeline Partners; and

     o    the obligation of the managing general partner's affiliates, which
          does not include the partnerships for this purpose, to pay Atlas
          Pipeline Partners the difference between the gathering fees to be paid
          by each partnership and the greater of $.35 per mcf or 16% of the
          gross sales price for the gas as described in "Proposed Activities -
          Sale of Natural Gas and Oil Production - Gathering of Natural Gas."

Other than certain guidelines set forth in "Conflicts of Interest," the managing
general partner has no established procedures to resolve a conflict of interest.

THE PRESENTMENT OBLIGATION MAY NOT BE FUNDED AND THE PRESENTMENT PRICE MAY NOT
REFLECT FULL VALUE. Subject to certain conditions, beginning with the fifth
calendar year after the offering of units in your partnership closes you may
present your units to the managing general partner for purchase. However, the
managing general partner may determine, in its sole discretion, that it does not
have the necessary cash flow or cannot borrow funds for this purpose on
reasonable terms. In either event the managing general partner may suspend the
presentment feature. This risk is increased because the managing general partner
has and will incur similar presentment obligations in other partnerships.

Further, the presentment price may not reflect the full value of a partnership's
property or your units because of the difficulty in accurately estimating
natural gas and oil reserves. Reservoir engineering is a subjective process of
estimating underground accumulations of natural gas and oil that cannot be
measured in an exact way, and the accuracy of the reserve estimate is a function
of the quality of the available data and of engineering and geological
interpretation and judgment. Also, the reserves and future net revenues are
based on various assumptions as to natural gas and oil prices, taxes,
development expenses, capital expenses, operating expenses and availability of
funds. Any significant variance in these assumptions could materially affect the
estimated quantity of the reserves. As a result, the managing general partner's
estimates are inherently imprecise and may not correspond to realizable value.
The presentment price paid for your units and any revenues received by you
before the presentment may be less than the purchase price of your units.
However, because the presentment price is a contractual price it is not reduced
by discounts such as minority interests and lack of marketability that generally
are used to value partnership interests for tax and other purposes.
(See "Presentment Feature.")

Finally, see "- An Investment in a Partnership Must be for the Long-Term Because
the Units Are Illiquid and Not Readily Transferable," above, concerning the tax
effects on you of presenting your units for purchase.

THE MANAGING GENERAL PARTNER MAY NOT DEVOTE THE NECESSARY TIME TO THE
PARTNERSHIPS BECAUSE ITS MANAGEMENT OBLIGATIONS ARE NOT EXCLUSIVE. The
partnerships do not have any employees and must rely on the managing general
partner and its affiliates, which may not devote the necessary time to the
partnerships. Also, the managing general partner depends on its parent company,
Atlas America, for management and administrative functions and financing for
capital expenditures as discussed in "Management - Transactions with Management
and Affiliates." The managing general partner and its affiliates will be engaged
in other oil and gas activities, including other partnerships and unrelated
business ventures for their own account or for the account of others, during the
term of each partnership. Thus, the competition for time and services of the
managing general partner and its affiliates could result in insufficient
attention to the management and operation of the partnerships.

PREPAYING SUBSCRIPTION PROCEEDS TO THE MANAGING GENERAL PARTNER MAY EXPOSE THE
SUBSCRIPTION PROCEEDS TO CLAIMS OF THE MANAGING GENERAL PARTNER'S CREDITORS.
Under the drilling and operating agreement, each partnership will be required to
immediately pay the managing general partner the investors' share of the entire
estimated price for drilling and completing the partnership's wells. Thus, these
funds could be subject to claims of the managing general partner's creditors.
(See "Financial Information Concerning the Managing General Partner and Atlas
America Public #15-2006(B) L.P.")

LACK OF INDEPENDENT UNDERWRITER MAY REDUCE DUE DILIGENCE INVESTIGATION OF THE
PARTNERSHIPS AND THE MANAGING GENERAL PARTNER. There has not been an extensive
in-depth "due diligence" investigation of the existing and proposed business
activities of the partnerships and the managing general partner that would be
provided by independent underwriters. Anthem Securities, which is affiliated
with the managing general partner, serves as dealer-manager and will receive
reimbursement of bona fide due diligence expenses for certain due diligence
investigations conducted by the selling agents which it will reallow to the
selling agents. However, Anthem Securities' due diligence examination concerning
the partnerships cannot be considered to be independent or as comprehensive as
an investigation that would be conducted by an independent broker/dealer. (See
"Conflicts of Interest.")

                                       17


A LENGTHY OFFERING PERIOD MAY RESULT IN DELAYS IN THE INVESTMENT OF YOUR
SUBSCRIPTION AND ANY CASH DISTRIBUTIONS FROM THE PARTNERSHIP TO YOU. Because the
offering period for a particular partnership can extend for many months, it is
likely that there will be a delay in the investment of your subscription
proceeds. This may create a delay in the partnership's cash distributions to you
which will be paid only after a portion of the partnership's wells have been
drilled, completed and placed on-line for the delivery and sale of natural gas
and/or oil, and payment has been received from the purchaser of the natural gas
and/or oil. Also, distributions of a partnership's net production revenues will
be made only after payment of the managing general partner's fees and expenses
and only if there is sufficient cash available in the managing general partner's
discretion. See "Terms of the Offering" for a discussion of the procedures
involved in the offering of the units and the formation of a partnership.

YOUR INTERESTS MAY BE DILUTED. The equity interests of you and the other
investors in a partnership may be diluted. You and the other investors will
share in a partnership's production revenues from all of its wells in proportion
to your respective number of units, based on $10,000 per unit, regardless of:

     o    when you subscribe;

     o    which wells are drilled with your subscription proceeds; or

     o    the actual subscription price you paid for your units as described
          below.

Because the drilling results of the wells drilled with the subscription proceeds
in your closing may be better than the drilling results of wells drilled with
subscription proceeds from your partnership's other closings, the value of your
units could be diluted when compared to what their value would have been if the
other units had not been sold and the other wells had not been drilled.

Also, some investors, including the managing general partner and its officers
and directors as described in "Plan of Distribution," may buy up to 5% of the
units in each partnership at discounted prices because the dealer-manager fee,
the sales commission, the reimbursement for bona fide due diligence expenses
and/or the accountable reimbursement for permissible non-cash compensation, will
not be paid for these sales. These discounted prices will reduce the net amount
of the subscription proceeds available to a partnership to drill wells. (See "-
Spreading the Risks of Drilling Among a Number of Wells Will be Reduced if Less
than the Maximum Subscription Proceeds are Received and Fewer Wells are
Drilled.") In addition, all of the investors in each partnership will share in
the partnership's production revenues with the managing general partner, based
on each investor's number of units purchased, rather than the purchase price
paid by the investor for his units. Thus, investors who pay discounted prices
for their units will receive higher returns on their investments in a
partnership as compared to investors who pay the entire $10,000 per unit.

TAX RISKS
YOUR DEDUCTION FOR INTANGIBLE DRILLING COSTS MAY BE LIMITED FOR PURPOSES OF THE
ALTERNATIVE MINIMUM TAX. You will be allocated a share of your partnership's
deduction for intangible drilling costs in the year in which you invest in an
amount equal to 90% of the subscription price you pay for your units. Under
current tax law, however, your alternative minimum taxable income in the year in
which you invest cannot be reduced by more than 40% by your deduction for
intangible drilling costs. (See "Federal Income Tax Consequences - Alternative
Minimum Tax.")

LIMITED PARTNERS NEED PASSIVE INCOME TO USE THEIR DEDUCTION FOR INTANGIBLE
DRILLING COSTS. If you invest in a partnership as a limited partner (except as
discussed below), your share of the partnership's deduction for intangible
drilling costs in the year in which you invest will be a passive loss which
cannot be used to offset "active" income, such as salary and bonuses, or
portfolio income, such as dividends and interest income. Thus, you may not have
enough passive income from the partnership or net passive income from your other
passive activities, if any, in the year in which you invest, to offset a portion
or all of your passive deduction for intangible drilling costs in the year in
which you invest. However, any unused passive loss from intangible drilling
costs may be carried forward by you to offset your passive income in subsequent
taxable years. Also, except as described below, the passive activity limitations
on your share of the partnership's deduction for intangible drilling costs in
the year in which you invest do not apply to you if you invest in the
partnership as a limited partner and you are a C corporation which:

                                       18


     o    is not a personal service corporation or a closely held corporation;

     o    is a personal service corporation in which employee-owners hold 10%
          (by value) or less of the stock, but is not a closely held
          corporation; or

     o    is a closely held corporation (i.e., five or fewer individuals own
          more than 50% (by value) of the stock), but is not a personal service
          corporation in which employee-owners own more than 10% (by value) of
          the stock, in which case you may use your passive losses to offset
          your net active income (calculated without regard to your passive
          activity income and losses or portfolio income and losses).

(See "Federal Income Tax Consequences - Limitations on Passive Activity Losses
 and Credits.")

YOU MAY OWE TAXES IN EXCESS OF YOUR CASH DISTRIBUTIONS FROM YOUR PARTNERSHIP.
You may become subject to income tax liability for partnership income in excess
of the cash and any marginal well production credits you receive from the
partnership in which you invest. For example:

     o    if the partnership borrows money, your share of partnership revenues
          used to pay principal on the loan will be included in your income from
          the partnership and will not be deductible;

     o    income from sales of natural gas and oil may be included in your
          income from the partnership in one tax year, although payment is not
          actually received by the partnership and, thus, cannot be distributed
          to you, until the next tax year;

     o    if there is a deficit in your capital account, the partnership may
          allocate income or gain to you even though you do not receive a
          corresponding distribution of partnership revenues;

     o    the partnership's revenues may be expended by the managing general
          partner for nondeductible costs or retained in the partnership to
          establish a reserve for future estimated costs, including a reserve
          for the estimated costs of eventually plugging and abandoning the
          wells, which will increase your share of the partnership's income
          without a corresponding cash distribution to you; and

     o    the taxable disposition of the partnership's property or your units
          may result in income tax liability to you in excess of the cash you
          receive from the transaction.

INVESTMENT INTEREST DEDUCTIONS OF INVESTOR GENERAL PARTNERS MAY BE LIMITED. If
you invest in a partnership as an investor general partner, your share of the
partnership's deduction for intangible drilling costs will reduce your
investment income and may reduce the amount of your deductible investment
interest expense, if any.

YOUR TAX BENEFITS FROM AN INVESTMENT IN A PARTNERSHIP ARE NOT CONTRACTUALLY
PROTECTED. An investment in a partnership does not give you any contractual
protection against the possibility that part or all of the intended tax benefits
of your investment will be disallowed by the IRS. No one provides any insurance,
tax indemnity or similar agreement for the tax treatment of your investment in a
partnership. You have no right to rescind your investment in the partnership or
to receive a refund of any of your investment in the partnership if a portion or
all of the intended tax consequences of your investment in the partnership are
ultimately disallowed by the IRS or the courts. Also, none of the fees paid by
the partnerships to the managing general partner, its affiliates or independent
third-parties (including special counsel which issued the tax opinion letter)
are refundable or contingent on whether the intended tax consequences of your
investment in a partnership are ultimately sustained if challenged by the IRS.

                                       19


AN IRS AUDIT OF YOUR PARTNERSHIP MAY RESULT IN AN IRS AUDIT OF YOUR PERSONAL
FEDERAL INCOME TAX RETURNS. The IRS may audit each partnership's federal
information income tax returns, particularly since each partnership's investors
will receive a deduction equal to not less than 90% of their investment amount
in the year in which they invest, which includes their respective deductions for
intangible drilling costs. If the partnership in which you invest is audited,
the IRS also may audit your personal federal income tax returns, including prior
years' returns and items which are unrelated to the partnership. (See "Federal
Income Tax Consequences - Penalties and Interest.")

EACH PARTNERSHIP'S DEDUCTIONS MAY BE CHALLENGED BY THE IRS. If the IRS audits a
partnership, it may challenge the amount of the partnership's deductions and the
taxable year in which the deductions were claimed, including the deductions for
intangible drilling costs and depreciation. Any adjustments made by the IRS to
the federal information income tax returns of the partnership in which you
invest could lead to adjustments on your personal federal income tax returns and
could reduce the amount of your deductions from the partnership in the year in
which you invest in the partnership and subsequent tax years. The IRS also could
seek to recharacterize a portion of the partnership's intangible drilling costs
for drilling and completing its wells as some other type of expense, such as
lease costs or equipment costs, which would reduce or defer your share of the
partnership's deductions for those costs. (See "Federal Income Tax Consequences
- - Business Expenses," "- Depreciation and Cost Recovery Deductions," and "-
Drilling Contracts.")

In addition, depending primarily on when its subscription proceeds are received,
it is possible that each partnership may prepay in the year in which its units
are sold either none, some, or all of its intangible drilling costs for wells
the drilling of which will not begin until the next taxable year. In that event,
you will not receive a deduction in the year in which you invest in a
partnership for your share of the partnership's prepaid intangible drilling
costs for those wells unless the drilling of the prepaid wells begins on or
before the 90th day following the close of the partnership's taxable year in
which the prepayment was made. Under the drilling and operating agreement, the
drilling of all of each partnership's prepaid wells, if any, will be required to
begin within that 90 day time period. However, the drilling of any partnership
well may be delayed due to circumstances beyond the control of the managing
general partner, acting as general drilling contractor, without liability to the
managing general partner. If for any reason the drilling of a prepaid
partnership well does not begin within the required 90 day time period, your
deduction for prepaid intangible drilling costs for that well must be claimed
for the tax year in which the well is actually drilled, instead of the tax year
in which you invested in the partnership and the intangible drilling costs were
prepaid. Also, there is a greater risk that the IRS will attempt to defer your
share of the partnership's deduction for intangible drilling costs from the year
in which you invest in the partnership to the subsequent year in which the well
is actually drilled if third-parties are participating with the partnership in
drilling those prepaid wells, because under their agreements with the managing
general partner or its affiliates the third-party working interest owners will
not be required to prepay their share of the costs of drilling and completing
the wells. (See "Federal Income Tax Consequences - Drilling Contracts.")

CHANGES IN THE LAW MAY REDUCE YOUR TAX BENEFITS FROM AN INVESTMENT IN A
PARTNERSHIP. Your tax benefits from an investment in a partnership may be
affected by changes in the tax laws. For example, the top four federal income
tax brackets for individuals were reduced in 2003, including reducing the top
bracket to 35% from 38.6%, until December 31, 2010. The lower federal income tax
rates will reduce to some degree the amount of taxes you save by virtue of your
share of the partnership's deductions for intangible drilling costs, depletion,
and depreciation, and its marginal well production credits, if any. However, the
federal income tax rates described above could be changed again, even before
January 1, 2011, and other changes in the tax laws could be made which would
affect your tax benefits from an investment in a partnership.

IT MAY BE MANY YEARS BEFORE YOU RECEIVE ANY MARGINAL WELL PRODUCTION CREDITS, IF
EVER. Beginning in 2005, there is a federal tax credit for the sale of qualified
marginal natural gas and oil production. Although the managing general partner
anticipates that each partnership's natural gas and oil production will be
qualified production for purposes of this tax credit, any natural gas and oil
production sold by Atlas America Public #15-2006(B) L.P. or Atlas America Public
#15-2006(C) L.P. in 2006 may be sold at prices above the applicable reference
prices for 2005 at which the marginal well production credit is reduced to zero.
In addition, depending primarily on market prices for natural gas and oil, which
are volatile, you may not receive any marginal well production credits from any
partnership in which you invest for many years, if ever. (See "Federal Income
Tax Consequences - Marginal Well Production Credits.")

                             ADDITIONAL INFORMATION


The program and the partnerships composing the program, other than Atlas America
Public #15-2005(A) L.P. which closed its offering on December 31, 2005,
currently are not required to file reports with the SEC. However, a registration
statement on Form S-1 has been filed on behalf of the program with the SEC.
Certain portions of the registration statement have been deleted from this
prospectus under SEC rules and regulations. You are urged to refer to the
registration statement, as amended, and its exhibits for further information
concerning the provisions of certain documents referred to in this prospectus.

You may read and copy any materials filed as a part of the registration
statement, including the tax opinion included as Exhibit 8, at the SEC's Public
Reference Room at 100 F Street, N.E., Washington, D.C. 20549. The SEC maintains
an internet world wide web site that contains registration statements, reports,
proxy statements, and other information about issuers who file electronically
with the SEC, including the program. The address of that site is
http://www.sec.gov. Also, you may obtain information on the operation of the
Public Reference Room by calling the SEC at 1-800-SEC-0330. In addition, a copy
of the tax opinion may be obtained by you or your advisors from the managing
general partner at no cost. The delivery of this prospectus does not imply that
its information is correct as of any time after its date.


                 FORWARD LOOKING STATEMENTS AND ASSOCIATED RISKS

Statements, other than statements of historical facts, included in this
prospectus and its exhibits address activities, events or developments that the
managing general partner and the partnerships anticipate will or may occur in
the future. For example, the words "believes," "anticipates," "will" and
"expects" are intended to identify forward-looking statements. These
forward-looking statements include such things as:

     o    investment objectives;

     o    references to future success in a partnership's drilling and marketing
          activities;

     o    business strategy;

     o    estimated future capital expenditures;

     o    competitive strengths and goals; and

     o    other similar matters.

These statements are based on certain assumptions and analyses made by the
partnerships and the managing general partner in light of their experience and
their perception of historical trends, current conditions, and expected future
developments. However, whether actual results will conform with these
expectations is subject to a number of risks and uncertainties, many of which
are beyond the control of the partnerships and the managing general partner,
including, but not limited to:

     o    general economic, market, or business conditions;

     o    changes in laws or regulations;

     o    the risk that the wells are productive, but do not produce enough
          revenue to return the investment made;

     o    the risk that the wells are dry holes; and

     o    uncertainties concerning the price of natural gas and oil, which may
          decrease.

                                       21


Thus, all of the forward-looking statements made in this prospectus and its
exhibits are qualified by these cautionary statements. There can be no assurance
that actual results will conform with the managing general partner's and the
partnerships' expectations.

                              INVESTMENT OBJECTIVES

Each partnership's principal investment objectives are to invest its
subscription proceeds in natural gas development wells which will:

     o    Provide monthly cash distributions to you from the partnership in
          which you invest until the wells are depleted, with a minimum annual
          return of capital of 10% during the first five years beginning with
          your partnership's first revenue distribution based on $10,000 per
          unit for all units sold. These distributions of a 10% return of
          capital during the first five years are not guaranteed, but are
          subject to the managing general partner's subordination obligation.
          The managing general partner anticipates that investors in a
          partnership will begin to receive monthly cash distributions
          approximately eight months after the offering period for the
          partnership ends and it may take up to 12 months before all of the
          wells in that partnership have been drilled and completed and are
          on-line for the sale of their natural gas or oil production. However,
          if all or the majority of the remaining units are sold in Atlas
          America Public #15-2006(B) L.P., then it may take longer for both cash
          distributions to begin and all of the wells to be drilled, completed
          and online to sell production in that partnership. This will also
          delay conversion of the investor general partner units to limited
          partner units. Also, see "Participation in Costs and Revenues -
          Subordination of Portion of Managing General Partner's Net Revenue
          Share" for a discussion of the subordination feature. The partnerships
          currently do not hold any interests in any prospects on which the
          wells will be drilled.

     o    Obtain tax deductions from the partnership in which you invest, in the
          year that you invest, from intangible drilling costs to offset a
          portion of your taxable income from sources other than the
          partnership, subject to the passive activity limitations on losses if
          you invest as a limited partner. For example, if you pay $10,000 for a
          unit your investment will produce an income tax deduction for
          intangible drilling costs of $9,000 per unit, 90%, in the year you
          invest against:

          o    ordinary income, or capital gain in some situations, if you
               invest as an investor general partner in a partnership; or

          o    passive net income from your other passive activity investments,
               if any, and passive income from the partnership in the year you
               invest, if any, if you invest as a limited partner in a
               partnership.

          In 2003, the top four tax brackets for individual taxpayers were
          reduced from 38.6% to 35%, 35% to 33%, 30% to 28%, and 27% to 25%.
          These changes are scheduled to expire December 31, 2010. If you are in
          either the 35% or 33% tax bracket, you will save approximately $3,150
          or $2,970, respectively, per $10,000 unit, in federal income taxes in
          the year that you invest. Most states also allow this type of a
          deduction against the state income tax. If the partnership in which
          you invest begins selling natural gas and oil production from its
          wells in the year in which you invest, however, then you may be
          allocated a share of partnership income in that year which will be
          offset by a portion of your intangible drilling cost deduction and
          your share of the other partnership deductions discussed below.

     o    Offset a portion of any gross production income generated by your
          partnership with tax deductions from percentage depletion, which is
          anticipated by the managing general partner to be 15% in 2006 and
          2007. The percentage depletion rate may fluctuate from year to year
          depending on the price of oil, but under current tax law it will not
          be less than the statutory rate of 15% nor more than 25%.

     o    Obtain tax deductions of the remaining 10% of your investment over a
          seven-year cost recovery period, beginning in the year the wells are
          drilled, completed and placed in service for production of natural gas
          or oil in the partnership in which you invest. For example, if you pay
          $10,000 for a unit, you will receive additional income tax deductions
          over the cost recovery period totaling $1,000 per unit for
          depreciation of your partnership's equipment costs for its productive
          wells.

                                       22


     o    If you are self-employed and invest in a partnership as an investor
          general partner, then you may use your share of the partnership's
          deduction for intangible drilling costs to offset a portion of your
          net earnings from self-employment in the year you invest. Also, if
          wells in the partnership are drilled and completed and placed in
          service in the year you invest, you will begin receiving the
          depreciation deductions discussed above which, to the extent they
          exceed your share of your partnership's income, if any, in the year in
          which you invest, also will reduce your net earnings from
          self-employment in the year you invest, and in your subsequent tax
          years during the seven-year cost recovery period.

Attainment of these investment objectives by a partnership will depend on many
factors, including the ability of the managing general partner to select
suitable wells that will be productive and produce enough revenue to return the
investment made. The success of each partnership depends largely on future
economic conditions, especially the future price of natural gas which is
volatile and may decrease. Also, the extent to which each partnership attains
the foregoing investment objectives will be different, because each partnership
is a separate business entity which:

     o    generally will drill different wells;

     o    will likely receive a different amount of subscription proceeds, as
          intended by the managing general partner, which generally will be the
          primary factor in determining the number of wells that can be drilled
          by each partnership; and

     o    may drill wells situated in different geographical areas, where the
          wells will be drilled to different formations, reservoirs or depths,
          which will affect the cost of the wells and, thus, will also affect
          the number of wells that can be drilled by each partnership.

There can be no guarantee that the foregoing objectives will be attained.

                     ACTIONS TO BE TAKEN BY MANAGING GENERAL
                      PARTNER TO REDUCE RISKS OF ADDITIONAL
                      PAYMENTS BY INVESTOR GENERAL PARTNERS

You may choose to invest in a partnership as an investor general partner so that
you can receive an immediate tax deduction against any type of income. To help
reduce the risk that you and other investor general partners could be required
to make additional payments to the partnership, the managing general partner
will take the actions set forth below.

     o    INSURANCE. The managing general partner will obtain and maintain
          insurance coverage in amounts and for purposes which would be carried
          by a reasonable, prudent general contractor and operator in accordance
          with industry standards. Each partnership will be included as an
          insured under these general, umbrella, and excess liability policies.
          In addition, the managing general partner requires all of its
          subcontractors to certify that they have acceptable insurance coverage
          for worker's compensation and general, auto, and excess liability
          coverage. Major subcontractors are required to carry general and auto
          liability insurance with a minimum of $1 million combined single limit
          for bodily injury and property damage in any one occurrence or
          accident. In the event of a loss caused by a major subcontractor, the
          managing general partner or partnership may attempt to draw on the
          insurance policy of the particular subcontractor before the insurance
          of the managing general partner or that of the partnership, but
          currently would be unable to do so since none of its major
          subcontractors have insurance which would allow this. Also, even if a
          major subcontractor's insurance was initially available, the managing
          general partner or a partnership may choose to draw on its own
          insurance coverage before that of the major subcontractor so that its
          insurance carrier will control the payment of claims.

                                       23


          The managing general partner's current insurance coverage satisfies
          the following specifications:

          o    worker's compensation insurance in full compliance with the laws
               of the Commonwealth of Pennsylvania and any other applicable
               state laws where the wells will be drilled;

          o    commercial general liability covering bodily injury and property
               damage third party liability, including products/completed
               operations, blow out, cratering, and explosion with limits of $1
               million per occurrence/$2 million general aggregate; and $1
               million products/completed operations aggregate;

          o    underground resources and equipment property damages liability to
               others with a limit of $1 million;

          o    automobile liability with a $1 million combined single limit;

          o    employer's liability with a $500,000 policy limit;

          o    pollution liability resulting from a "pollution incident," which
               is defined as the discharge, dispersal, seepage, migration,
               release or escape of one or more pollutants directly from a well
               site, with a limit of $1 million for bodily injury and property
               damage and a limit of $100,000 for clean-up for third-parties;
               however, coverage does not apply to pollution damage to the well
               site itself or the property of the insured;

          o    commercial umbrella liability composed of:

               o    primary umbrella limit of $25 million over general
                    liability, automobile liability, and employer's liability
                    and a $10 million sublimit for pollution liability; and

               o    excess liability providing excess limits of $24 million over
                    the $25 million provided in the commercial umbrella, but
                    excluding pollution liability.

          Because the managing general partner is driller and operator of wells
          for other partnerships, the insurance available to each partnership
          could be substantially less if insurance claims are made in the other
          partnerships.

          This insurance has deductibles, which would first have to be paid by a
          partnership, of:

          o    $2,500 per occurrence for bodily injury and property damage; and

          o    $10,000 per pollution incident for pollution damage.

          The insurance also has terms, including exclusions, which are standard
          for the natural gas and oil industry. On request the managing general
          partner will provide you or your representative a copy of its
          insurance policies. The managing general partner will use its best
          efforts to maintain insurance coverage that meets its current
          coverage, but it may be unsuccessful if the coverage becomes
          unavailable or too expensive.

          If you are an investor general partner and there is going to be a
          material adverse change in your partnership's insurance coverage,
          which the managing general partner does not anticipate, then the
          managing general partner will notify you at least 30 days before the
          effective date of the change. You will then have the right to convert
          your units into limited partner units before the change in insurance
          coverage by giving written notice to the managing general partner.

                                       24



     o    CONVERSION OF INVESTOR GENERAL PARTNER UNITS TO LIMITED PARTNER UNITS.
          Your investor general partner units will be automatically converted by
          the managing general partner to limited partner units after all of the
          wells in your partnership have been drilled and completed. In each
          partnership, the managing general partner anticipates that all of the
          wells will be drilled and completed no more than 12 months after a
          partnership closes, and the conversion will then follow. However, if
          all or the majority of the remaining units are sold in Atlas America
          Public #15-2006(B) L.P., then it may take longer for both cash
          distributions to begin and all of the wells to be drilled, completed
          and online to sell production in that partnership. This will also
          delay conversion of the investor general partner units to limited
          partner units.

          Once your units are converted, which is a nontaxable event, you will
          have the lesser liability of a limited partner in your partnership
          under Delaware law for obligations and liabilities arising after the
          conversion. However, you will continue to have the responsibilities of
          a general partner for partnership liabilities and obligations incurred
          before the effective date of the conversion. For example, you might
          become liable for partnership liabilities in excess of your
          subscription amount during the time the partnership is engaged in
          drilling activities and for environmental claims that arose during
          drilling activities, but were not discovered until after conversion.

     o    NONRECOURSE DEBT. The partnerships do not anticipate that they will
          borrow funds. However, if borrowings are required, then the
          partnerships will be permitted to borrow funds only from the managing
          general partner or its affiliates and without recourse against
          non-partnership assets. Thus, if there is a default under this loan
          arrangement you cannot be required to contribute funds to the
          partnership. Any borrowings by a partnership will be repaid from that
          partnership's revenues.

          The amount that may be borrowed at any one time by a partnership may
          not exceed an amount equal to 5% of the investors' subscription
          proceeds in the partnership. However, because you do not bear the risk
          of repaying these borrowings with non-partnership assets, the
          borrowings will not increase the extent to which you are allowed to
          deduct your individual share of partnership losses. (See "Federal
          Income Tax Consequences - Tax Basis of Units" and "- `At Risk'
          Limitation on Losses.")

     o    INDEMNIFICATION. The managing general partner will indemnify you from
          any liability incurred in connection with your partnership that is in
          excess of your interest in the partnership's:

          o    undistributed net assets; and

          o    insurance proceeds, if any, from all potential sources.

          The managing general partner's indemnification obligation, however,
          will not eliminate your potential liability if the managing general
          partner's assets are insufficient to satisfy its indemnification
          obligation. There can be no assurance that the managing general
          partner's assets, including its liquid assets, will be sufficient to
          satisfy its indemnification obligation.

             CAPITALIZATION AND SOURCE OF FUNDS AND USE OF PROCEEDS

SOURCE OF FUNDS
Each partnership must receive minimum subscription proceeds of $2 million to
close, and the subscription proceeds of both partnerships, in the aggregate, may
not exceed $147,726,000, which is the remaining portion of the unsold units from
the original $200 million registration. There are no other requirements
regarding the size of a partnership, and the subscription proceeds of one
partnership may be substantially more or less than the subscription proceeds of
the other partnerships. See the targeted maximum subscription amounts for each
partnership set forth in "Terms of the Offering - Subscription to a
Partnership." Also, the managing general partner has the discretion to accept
subscriptions for any amount up to and including the entire amount in Atlas
America Public #15-2006(B) L.P. and not offer and sell any units in the other
partnership. (See "Terms of the Offering - Subscription to a Partnership.")


                                       25


On completion of the offering of units in a partnership, the partnership's
source of funds will be as follows assuming each unit is sold for $10,000:

     o    the subscription proceeds of you and the other investors, which will
          be:

          o    $2 million if 200 units are sold; and

          o    $147,726,000 if 14,772.6 units are sold; and


     o    the managing general partner's capital contribution, which must be at
          least 25% of all capital contributions and includes its credit for
          organization and offering costs and contributing the leases, which
          will be:

          o    not less than $666,667 if 200 units are sold; and

          o    not less than $49,242,000 if 14,772.6 units are sold.

Thus, the total amount available to a partnership will be not less than
$2,666,667 if 200 units are sold ranging to not less than $196,968,000 if
14,772.6 units are sold.

The managing general partner has made the largest single capital contribution in
each of its prior partnerships and no individual investor has contributed more,
although the total investor contributions in each partnership have exceeded the
managing general partner's contribution. The managing general partner also
expects to make the largest single capital contribution in each of the
partnerships.

USE OF PROCEEDS
The subscription proceeds received from you and the other investors will be used
by the partnership in which you invest as follows:

     o    90% of the subscription proceeds will be used to pay 100% of the
          intangible drilling costs of drilling and completing the partnership's
          wells; and

     o    10% of the subscription proceeds will be used to pay a portion of the
          equipment costs of drilling and completing the partnership's wells.

The managing general partner will contribute all of the leases to each
partnership covering the acreage on which the partnership's wells will be
drilled, and pay all of the equipment costs of drilling and completing the
partnership's wells that exceed 10% of the partnership's subscription proceeds.
Thus, the managing general partner will pay the majority of each partnership's
equipment costs. The managing general partner also will be charged with 100% of
the organization and offering costs for each partnership. A portion of these
contributions to each partnership will be in the form of payments to itself, its
affiliates and third-parties and the remainder will be in the form of services
related to organizing this offering. The managing general partner will receive a
credit towards its required capital contribution to each partnership for these
payments and services as discussed in "Participation in Costs and Revenues."

The following tables present information concerning each partnership's use of
the proceeds provided by both you and the other investors and the managing
general partner. The tables are based in part on the managing general partner's
estimate of its capital contribution to a partnership based on the applicable
number of units sold as shown in the table. The managing general partner's
estimated capital contribution shown in the tables includes its credit for
organization and offering costs and contributing the leases, and exceeds in each
case its required capital contribution of not less than 25% of all capital
contributions for a partnership. Anthem Securities, an affiliate of the managing
general partner, will be the dealer-manager of the offering and it will receive
the dealer-manager fee, the sales commissions, the .5% reimbursement for
permissible non-cash compensation, and the up to .5% reimbursement for bona fide
due diligence expenses. A portion of these payments and reimbursements,
including all of the up to .5% reimbursement for bona fide due diligence
expenses, will be reallowed by the dealer-manager to the broker/dealers, which
are referred to as selling agents, as discussed in "Plan of Distribution."
Subject to the above, the organizational costs will be paid to the managing
general partner, its affiliates and various third-parties, and the intangible
drilling costs and tangible costs will be paid to the managing general partner
as general drilling contractor and operator under the drilling and operating
agreement.


The tables are presented based on:

     o    the sale of 200 units ($2 million), which is the minimum number of
          units for each partnership; and

     o    the sale of 14,772.6 units, which are all of the remaining unsold
          units from the original 20,000 units ($200 million) registered.

Substantially all of the proceeds available to each partnership will be expended
for the following purposes and in the following manner:

(1)    The percentage is based on the managing general partner's estimate of its
       capital contribution, and excludes the total investors' subscription
       proceeds set forth in the "- Investor Capital" table above.
(2)    As discussed in "Participation in Costs and Revenues," if these fees,
       sales commissions, reimbursements and organization costs exceed 15% of
       the investors' subscription proceeds in a partnership, then the excess
       will be charged to the managing general partner, but will not be included
       as part of its capital contribution.
(3)    The managing general partner's share of equipment costs is described in
       "Compensation - Drilling Contracts." However, these costs will vary
       depending on the actual equipment costs of drilling and completing the
       wells. Also, see footnote (2) to the "- Investor Capital" table above.
(4)    Instead of contributing cash for the leases, the managing general partner
       will assign to each partnership the leases covering the acreage on which
       the partnership's wells will be drilled. Generally, as described in
       "Compensation - Lease Costs," the managing general partner's lease cost
       is approximately $8,411 per prospect. For purposes of this table, the
       managing general partner's lease costs have been quantified using this
       amount based on its estimate of the number of net wells that will be
       drilled with the subscription proceeds available as set forth in the
       table. The actual number of net wells drilled by the partnerships is
       likely to vary from the managing general partner's estimate, based
       primarily on where the wells are drilled and the actual costs of the
       wells. Also, the managing general partner's lease costs on a prospect may
       be significantly higher than the above-referenced amount, and its credit
       for the leases contributed will equal its cost, unless it has a reason to
       believe that cost is materially more than fair market value of the
       property, in which case its credit for its lease contribution must not
       exceed fair market value.

       used to pay intangible drilling costs and 10% will be used to pay
       equipment costs. (Also, see footnote (2) to the "- Investor Capital"
       table, above.)
(4)    Instead of contributing cash for the leases, the managing general partner
       will assign to each partnership the leases covering the acreage on which
       that partnership's wells will be drilled as set forth in footnote (4) to
       the "- Managing General Partner Capital" table above.

                                  COMPENSATION

The items of compensation to be paid to the managing general partner and its
affiliates from each partnership are set forth below. Most of these items of
compensation depend on how many wells a partnership drills and how much of the
working interest in each of the wells is owned by the partnership. In this
regard, the managing general partner estimates that approximately eight gross
and net wells will be drilled if the minimum required subscription proceeds of
$2 million are received by a partnership, and approximately 617 gross wells,
which will be approximately 588.5 net wells, will be drilled, in the aggregate,
if subscription proceeds of $147,726,000 are received by a partnership or the
partnerships.

A gross well is a well in which a partnership owns a working interest. This is
compared with a net well which is the sum of the fractional working interests
owned in the gross wells. For example, a 50% working interest owned in three
wells is three gross wells, but 1.5 net wells. However, the managing general
partner's estimate set forth above of the number of wells to be drilled is
subject to risks which can cause actual results to vary. (See "Risk Factors -
Risks Related to an Investment in a Partnership - The Partnerships Do Not Own
Any Prospects, the Managing General Partner Has Complete Discretion to Select
Which Prospects are Acquired By a Partnership, and The Possible Lack of
Information for a Majority of the Prospects Decreases Your Ability to Evaluate
the Feasibility of a Partnership.")

                                       29


NATURAL GAS AND OIL REVENUES
Subject to the managing general partner's subordination obligation, the
investors and the managing general partner will share in each partnership's
revenues in the same percentages as their respective capital contributions bear
to the total partnership capital contributions for that partnership except that
the managing general partner will receive an additional 7% of that partnership's
revenues. However, the managing general partner's total revenue share may not
exceed 40% of that partnership's revenues regardless of the amount of its
capital contribution.

For example, if the managing general partner contributes the minimum of 25% of
the total partnership capital contributions and the investors contribute 75% of
the total partnership capital contributions, then the managing general partner
will receive 32% of the partnership revenues and the investors will receive 68%
of the partnership revenues. On the other hand, if the managing general partner
contributes 35% of the total partnership capital contributions and the investors
contribute 65% of the total partnership capital contributions, then the managing
general partner will receive 40% of the partnership revenues, not 42%, because
its revenue share cannot exceed 40% of partnership revenues, and the investors
will receive 60% of partnership revenues.

As noted above, the managing general partner's revenue share from each
partnership is subject to its subordination obligation as described in
"Participation in Costs and Revenues - Subordination of Portion of the Managing
General Partner's Net Revenue Share" and the accompanying tables. For example,
if the managing general partner's revenue share is 35% of the partnership
revenues, then up to 17.5% of the managing general partner's partnership net
revenues could be used for its subordination obligation.

LEASE COSTS
Under the partnership agreement the managing general partner will contribute to
each partnership all the undeveloped leases necessary to cover each of the
partnership's prospects. The managing general partner will receive a credit to
its capital account equal to:

     o    the cost of the leases; or

     o    the fair market value of the leases if the managing general partner
          has reason to believe that cost is materially more than the fair
          market value.

The cost of the leases will include a portion of the managing general partner's
reasonable, necessary, and actual expenses for services allocated to a
partnership's leases by it using industry guidelines.

In the primary areas of interest, the managing general partner's lease cost is
approximately $8,411 per prospect assuming a partnership acquires 100% of the
working interest in the prospect. From time to time, however, the managing
general partner's lease costs on a prospect may be significantly higher than
this amount. The managing general partner's credit for lease costs will be
proportionally reduced to the extent a partnership acquires less than 100% of
the working interest in the prospect. In this regard, a working interest
generally means an interest in the lease under which the owner of the working
interest must pay some portion of the cost of development, operation, or
maintenance of the well. Assuming all the leases are situated in these areas,
the managing general partner estimates that its credit for lease costs will be:

     o    $67,288 if $2 million is received, which is eight net wells times
          $8,411 per prospect; and

     o    $4,949,874 if $147,726,000 is received, which is 588.5 net wells times
          $8,411 per prospect.

Drilling a partnership's wells also may provide the managing general partner
with offset prospects to be drilled by allowing it to determine at the
partnership's expense the value of adjacent acreage in which the partnership
would not have any interest.

DRILLING CONTRACTS
Each partnership will enter into the drilling and operating agreement with the
managing general partner to drill and complete each partnership's wells at cost
plus a nonaccountable fixed payment reimbursement to the managing general
partner for the investors' share of its general and administrative overhead of
$15,000 per well plus 15% of the cost and the nonaccountable fee of $15,000
described above. The managing general partner has determined that this is a
competitive rate based on:


                                       30


     o    information it has concerning drilling rates of third-party drilling
          companies in the Appalachian Basin;

     o    the estimated costs of non-affiliated persons to drill and equip wells
          in the Appalachian Basin as reported for 2003 by an independent
          industry association which surveyed other non-affiliated operators in
          the area; and

     o    information it has concerning increases in drilling costs in the area
          since 2003.

If this rate subsequently exceeds competitive rates available from other
non-affiliated persons in the area engaged in the business of rendering or
providing comparable services or equipment, then the rate will be adjusted to
the competitive rate. However, the 15% premium and the investors' share of the
managing general partner's nonaccountable fixed payment reimbursement of its
general and administrative overhead in the amount of $15,000 per well may not be
increased by the managing general partner during the term of the partnership.


The managing general partner expects to subcontract some of the actual drilling
and completion of each partnership's wells to third-parties selected by it.
However, the managing general partner may not benefit by interpositioning itself
between the partnership and the actual provider of drilling contractor services,
and may not profit by drilling in contravention of its fiduciary obligations to
the partnership.

Cost, when used with respect to services, generally means the reasonable,
necessary, and actual expense incurred in providing the services, determined in
accordance with generally accepted accounting principles. The cost of the well
includes all ordinary costs of drilling, testing and completing the well. This
includes the cost of the following for a natural gas well, which will be the
classification of the majority of the wells:

     o    multiple completions, which means, in general, treating separately all
          potentially productive geological formations in an attempt to enhance
          the natural gas production from the well;

     o    installing gathering lines for the natural gas of up to 2,500 feet;
          and

     o    the necessary facilities for the production of natural gas.

The amount paid to the managing general partner for drilling and completing a
partnership well will be proportionately reduced to the extent the partnership
acquires less than 100% of the working interest in the prospect. In addition,
the amount of compensation that the managing general partner could earn as a
result of these arrangements depends on many other factors as well, including
the following:

     o    where the wells are drilled and their depths;

     o    the method used to complete the well; and

     o    the number of wells drilled.

Assuming the maximum subscription proceeds of $147,726,000 are received, the
managing general partner anticipates that the partnerships' weighted average
cost of drilling and completing approximately 588.5 net wells, excluding lease
costs, will be approximately $313,926 per net well, which includes the
nonaccountable, fixed payment reimbursement of $15,000 per well to the managing
general partner for the investors' share of its general and administrative
overhead and the 15% premium paid to the managing general partner. This estimate
also was based on the managing general partner's estimate of:

     o    the number of wells that will be drilled in each area by the
          partnerships;

     o    the percentage of working interest that the partnerships will acquire
          in the prospects in each area; and

                                       31


     o    the estimated drilling and completion costs of the wells to be drilled
          by the partnerships, which are different for wells in each area based
          primarily on different depths and completion methods.

Thus, the managing general partner's estimated weighted average cost of drilling
and completing one net well as set forth above, in all likelihood, will vary
from the actual average cost of the wells in each of the primary areas and for
the partnerships separately and as a whole.

Based on the assumptions and the estimated weighted average cost for one net
well as set forth above, the managing general partner expects that its 15%
profit will be approximately $32,803 per net well (the managing general partner
anticipates that the partnerships will acquire less than 100% of the working
interest in some of their respective prospects) with respect to the intangible
drilling costs and the portion of equipment costs paid by you and the other
investors. The actual compensation received by the managing general partner as a
result of each partnership's drilling operations will vary from these estimates,
but the managing general partner's profit will not in any event exceed 15% of
the costs of drilling and completing the wells.

Subject to the foregoing, the managing general partner estimates that its
nonaccountable, fixed payment reimbursement for general and administrative
overhead of $15,000 and profit of 15% (approximately $32,803) for one net well,
which totals $47,803, will be:

     o    $382,424 if $2 million is received, which is eight net wells times
          $47,803; and

     o    $28,132,066 if $147,726,000 is received, which is 588.5 net wells
          times $47,803.

The managing general partner's estimated weighted average cost of $313,926 for
one net well as discussed above consists of:

     o    intangible drilling costs of approximately $225,919 (72%); and

     o    equipment costs of approximately $88,007 (28%).

In this regard, the managing general partner further anticipates that a
partnership's cost of drilling and completing any given well in the
partnerships' primary areas as described in "Proposed Activities," excluding
lease costs, may range from as low as approximately $178,000 to as high as
$423,000 or more, depending on the area.

PER WELL CHARGES
Under the drilling and operating agreement the managing general partner, as
operator of the wells, will receive the following from each partnership when the
wells begin producing:

     o    reimbursement at actual cost for all direct expenses incurred on
          behalf of the partnership; and

     o    well supervision fees for operating and maintaining the wells during
          producing operations at a competitive rate.

Currently the competitive rate for well supervision fees is $285 per well per
month in the primary and secondary areas. The well supervision fees will be
proportionately reduced to the extent the partnership acquires less than 100% of
the working interest in the well, and may be adjusted for inflation annually
beginning with the second calendar year after a partnership closes. If in the
future the foregoing rate exceeds competitive rates available from other
non-affiliated persons in the area engaged in the business of providing
comparable services or equipment, then the rate will be adjusted to the
competitive rate. The managing general partner may not benefit by
interpositioning itself between the partnership and the actual provider of
operator services. In no event will any consideration received for operator
services be duplicative of any consideration or reimbursement received under the
partnership agreement.

                                       32


The well supervision fee covers all normal and regularly recurring operating
expenses for the production, delivery, and sale of natural gas and oil, such as:

     o    well tending, routine maintenance, and adjustment;

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

     o    preparing reports to the partnership and to government agencies.

The well supervision fees do not include costs and expenses related to:

     o    the purchase of equipment, materials, or third-party services;

     o    brine disposal; and

     o    rebuilding of access roads.

These costs will be charged at the invoice cost of the materials purchased or
the third-party services performed.

The managing general partner estimates that it will receive well supervision
fees for a partnership's first 12 months of operation after all of the wells
have been placed in production of:

     o    $27,360 if $2 million is received, which is eight net wells at $285
          per well per month; and

     o    $2,012,670 if $147,726,000 is received, which is 588.5 net wells at
          $285 per well per month.

GATHERING FEES
Under the partnership agreement the managing general partner will be responsible
for gathering and transporting the natural gas produced by the partnerships to
interstate pipeline systems, local distribution companies, and/or end-users in
the area (the "gathering services"). The managing general partner anticipates
that it will use the gathering system owned by Atlas Pipeline Partners for the
majority of the natural gas as described in "Proposed Activities - Sale of
Natural Gas and Oil Production - Gathering of Natural Gas." The managing general
partner's affiliate, Atlas America, Inc., which is sometimes referred to in this
prospectus as "Atlas America," or another affiliate controls and manages the
gathering system for Atlas Pipeline Partners. (See "Management - Organizational
Diagram and Securities Ownership of Beneficial Owners.") Also, Atlas America and
the managing general partner's affiliates, Resource Energy, Inc., sometimes
referred to in this prospectus as "Resource Energy," and Viking Resources
Corporation, sometimes referred to in this prospectus as "Viking Resources,"
(the "Atlas Entities"), which do not include the partnerships, have an agreement
with Atlas Pipeline Partners which provides that generally all of the gas
produced by their affiliated partnerships, which includes each partnership
composing the program, will be gathered and transported through the gathering
system owned by Atlas Pipeline Partners and that the Atlas Entities must pay the
greater of $.35 per mcf or 16% of the gross sales price for each mcf transported
by these affiliated partnerships through Atlas Pipeline Partners' gathering
system. Gross sales price means the price that is actually received, adjusted to
take into account proceeds received or payments made pursuant to hedging
arrangements. Subject to the agreement with Atlas Pipeline Partners described
above, in providing the gathering services the managing general partner may use
gathering systems owned by Atlas Pipeline Partners, independent third-parties
and/or affiliates of Atlas America other than Atlas Pipeline Partners.

Each partnership will pay a gathering fee directly to the managing general
partner at competitive rates for the gathering services. The gathering fee paid
by the partnership to the managing general partner may be increased from
time-to-time by the managing general partner, in its sole discretion, but may
not increase beyond competitive rates as determined by the managing general
partner. Currently, the managing general partner has determined that the
competitive fee in each of its primary and secondary areas where it drills its
wells is an amount equal to 10% of the gross sales price received by each
partnership for its natural gas. Gross sales price means the price that is
actually received, adjusted to take into account proceeds received or payments
made pursuant to hedging arrangements. The payment of a competitive fee to the
managing general partner for its gathering services shall be subject to the
following conditions:

                                       33


     o    If the gathering system owned by Atlas Pipeline Partners is used by a
          partnership, then the managing general partner will apply the
          gathering fee it receives from the partnership towards the payments
          owed by the Atlas Entities under their agreement with Atlas Pipeline
          Partners.

     o    If a third-party gathering system is used by a partnership, the
          managing general partner will pay a portion or all of the gathering
          fee it receives from the partnership to the third-party gathering the
          natural gas. The managing general partner may retain the excess of any
          gathering fees it receives from the partnership over the payments it
          makes to third-party gas gatherers. If the third-party's gathering
          system charges more than an amount equal to 10% of the gross sales
          price, then the managing general partner's gathering fee charged to a
          partnership will be the actual transportation and compression fees
          charged by the third-party gathering system with respect to the
          partnership's natural gas in the area.

     o    If both a third-party gathering system and the Atlas Pipeline Partners
          gathering system (or a gas gathering system owned by an affiliate of
          Atlas America other than Atlas Pipeline Partners) are used by a
          partnership, then the managing general partner will receive an amount
          equal to 10% of the gross sales price plus the amount charged by the
          third-party gathering system. For purposes of illustration, but not
          limitation, certain wells drilled by a partnership in the Upper
          Devonian Sandstone Reservoirs in the McKean County, Pennsylvania
          secondary area will deliver natural gas produced in this area into a
          gathering system, a segment of which will be provided by Atlas
          Pipeline Partners and a segment of which will be provided by a
          third-party. The third-party will receive gathering fees of $.35 per
          mcf for transportation and compression, which may be increased from
          time-to-time, and the managing general partner will receive a
          gathering fee equal to 10% of the gross sales price.

Finally, in connection with the Knox project in the Mississippian and Devonian
Shale Reservoirs in Anderson, Campbell, Morgan, Roane and Scott Counties,
Tennessee area, as discussed in "Proposed Activities--Primary Areas of
Operations--Mississippian Carbonate and Devonian Shale Reservoirs in Anderson,
Campbell, Morgan, Roane and Scott Counties, Tennessee," a partnership will
deliver natural gas into a gathering system provided by Knox Energy, which is
referred to as the Coalfield Pipeline. The Coalfield Pipeline will receive
gathering fees of $.55 per mcf plus fees for compression, which may be increased
from time-to-time. If the Coalfield Pipeline does not have sufficient capacity
to compress and transport the natural gas produced from a partnership's wells as
determined by Atlas America, then Atlas America or an affiliate other than Atlas
Pipeline Partners may construct an additional gathering system and/or
enhancements to the Coalfield Pipeline. On completion of the construction, Atlas
America will transfer its ownership in the additional gathering system and/or
enhancements to the owners of the Coalfield Pipeline, which will then pay Atlas
America an amount equal to $.12 per mcf of natural gas transported through the
newly constructed and/or enhanced gathering system. If the events described
above occur, Coalfield Pipeline will pay this amount to Atlas America from the
gathering and compression fees it charges to a partnership.

The actual amount of gathering fees to be paid by a partnership to the managing
general partner cannot be quantified, because the volume of natural gas that
will be produced and transported from the partnership's wells cannot be
predicted.

DEALER-MANAGER FEES
Subject to certain exceptions described in "Plan of Distribution," Anthem
Securities, the dealer-manager and an affiliate of the managing general partner,
will receive on each unit sold to an investor:

     o    a 2.5% dealer-manager fee;

                                       34


     o    a 7% sales commission;

     o    a .5% reimbursement for accountable permissible non-cash compensation;
          and

     o    an up to .5% reimbursement of the selling agents' bona fide due
          diligence expenses.

Assuming the above amounts are paid for all units sold, the dealer-manager
will receive:

     o    $210,000 if $2 million is received by a partnership; and

     o    $15,511,230 if $147,726,000 is received by the partnerships.

        All of the reimbursement of the selling agents' bona fide due diligence
        expenses, and generally all of the sales commissions, will be reallowed
        to the selling agents. A portion of the 2.5% dealer-manager fee will be
        reallowed to the wholesalers who are associated with the managing
        general partner and registered through Anthem Securities for
        subscriptions obtained through their efforts. The dealer-manager will
        retain any of the compensation which is not reallowed. See "Management"
        for the ownership of Anthem Securities.

INTEREST AND OTHER COMPENSATION
The managing general partner or an affiliate will have the right to charge a
competitive rate of interest on any loan it may make to or on behalf of a
partnership. If the managing general partner provides equipment, supplies, and
other services to a partnership, then it may do so at competitive industry
rates. The managing general partner will determine competitive industry rates
for equipment, supplies and other services by conducting a survey of the
interest and/or fees charged by unaffiliated third-parties in the same
geographic area engaged in similar businesses. If possible, the managing general
partner will contact at least two unaffiliated third-parties, however, the
managing general partner will have sole discretion in determining the amount to
be charged a partnership.

ESTIMATE OF ADMINISTRATIVE COSTS AND DIRECT COSTS TO BE BORNE BY THE
PARTNERSHIPS
The managing general partner and its affiliates will receive from each
partnership a nonaccountable, fixed payment reimbursement for their
administrative costs, which has been determined by the managing general partner
to be $75 per well per month. This payment per well is subject to the following:

     o    it will not be increased in amount during the term of the partnership;

     o    it will be proportionately reduced to the extent the partnership
          acquires less than 100% of the working interest in the well;

     o    it will be the entire payment to reimburse the managing general
          partner for the partnership's administrative costs; and

     o    it will not be received for plugged or abandoned wells.

The managing general partner estimates that the nonaccountable, fixed payment
reimbursement for administrative costs allocable to a partnership's first 12
months of operation after all of its wells have been placed into production will
not exceed approximately:

     o    $7,200 if $2 million is received, which is eight net wells at $75 per
          well per month; and

     o    $529,650 if $147,726,000 is received, which is 588.5 net wells at $75
          per well per month.


                                       35


Direct costs will be determined by the managing general partner, in its sole
discretion, including the provider of the services or goods and the amount of
the provider's compensation. Direct costs will be billed directly to and paid by
each partnership to the extent practicable. The anticipated direct costs set
forth below for a partnership's first 12 months of operation after all of its
wells have been placed into production may vary from the estimates shown for
numerous reasons which cannot accurately be predicted. These reasons include:

     o    the number of investors;

     o    the number of wells drilled;

     o    the partnership's degree of success in its activities;

     o    the extent of any production problems;

     o    inflation; and

     o    various other factors involving the administration of the partnership.

(1)  This assumes three partnerships are formed as described below in "Terms of
     the Offering - Subscription to a Partnership" and the targeted nonbinding
     subscriptions of each partnership are received.


                              TERMS OF THE OFFERING

SUBSCRIPTION TO A PARTNERSHIP

Atlas America Public #15-2005 Program is a series of up to three limited
partnerships which have been formed under the Delaware Revised Uniform Limited
Partnership Act to offer for sale units in an aggregate amount of $200 million.
The first partnership in the program, Atlas America Public #15-2005(A) L.P.,
completed its offering on December 31, 2005 and received offering proceeds of
$52,245,720, which included units sold on a discounted basis as described in
"Plan of Distribution." Thus, the total maximum subscriptions remaining from the
original $200 million, based on the number of units previously sold, are
$147,726,000, which is 14,772.6 units at $10,000 per unit assuming no units are
sold at the discounted prices described in "Plan of Distribution."

The targeted subscriptions for each partnership are set forth below. These
targeted amounts are not mandatory, and the managing general partner may
determine the final subscription amount for each partnership in its sole
discretion. The maximum subscription of any partnership offered in 2006,
however, must be the lesser of:

     o    $147,726,000; or

     o    $147,726,000 less the total subscription proceeds received by any
          prior partnership offered in 2006.

Also set forth below are the targeted ending dates for the remaining
partnerships, which are not binding except that the units in each partnership
may not be offered beyond that partnership's offering termination date as set
forth below. The managing general partner may close the offering of units in a
partnership at any time before that partnership's offering termination date once
the partnership is in receipt of the minimum required subscriptions, and the
managing general partner may withdraw the offering of units in any partnership
at any time.

                                       36





                                    REQUIRED            TARGETED             TARGETED         OFFERING

Atlas America Public #15-2006(C)    $2 million          $22.726 million      12/31/06         12/31/06



     o    The units in the above partnerships will be offered and sold only
          during 2006.

- ----------
(1)  The partnerships will be offered in a series. Thus, units in Atlas America
     Public #15-2006(C) L.P. will not be offered until the offering of units in
     Atlas America Public #15-2006(B) L.P. has terminated. Units in Atlas
     America Public #15-2006(D) L.P. will not be offered.

Units are offered at a subscription price of $10,000 per unit, subject to
certain exceptions which are described in "Plan of Distribution," and must be
paid 100% in cash at the time of subscribing. The subscription price of the
units has been arbitrarily determined by the managing general partner because
the partnerships do not have any prior operations, assets, earnings, liabilities
or present value. Your minimum subscription is one unit ($10,000). Larger
fractional subscriptions will be accepted in $1,000 increments, beginning with
$11,000, $12,000, etc.

You will have the election to purchase units in a partnership as either an
investor general partner or a limited partner. However, the managing general
partner will have exclusive management authority for each partnership. Each
partnership will be a separate business entity from the other partnerships.
Thus, as an investor, you will be a partner only in the partnership in which
you invest. You will have no interest in the business, distributions, assets or
tax benefits of the other partnerships unless you also invest in the other
partnerships. Your investment return will depend solely on the operations and
success or lack of success of the particular partnership in which you invest.

PARTNERSHIP CLOSINGS AND ESCROW
You and the other investors should make your checks for units payable to "Atlas
America Public #15-2006(B) L.P., Escrow Agent, National City Bank of PA" or
"Atlas America Public #15-2006(C) L.P., Escrow Agent, National City Bank of PA,"
depending on which partnership is then being offered at the time you subscribe
for units, and give your check to your broker/dealer for submission to the
dealer-manager and escrow agent. Subscription proceeds for each partnership will
be held in a separate interest bearing escrow account at National City Bank of
Pennsylvania until receipt of the minimum subscription proceeds. A partnership
may not break escrow unless the partnership is in receipt of subscription
proceeds of $2 million after the discounts described in "Plan of Distribution"
and excluding any subscriptions by the managing general partner or its
affiliates. However, on receipt of the minimum subscription proceeds and written
instructions to the escrow agent from the managing general partner and the
dealer-manager, the managing general partner on behalf of a partnership may
break escrow and transfer the escrowed funds to a partnership account, enter
into the drilling and operating agreement with itself or an affiliate as
operator, and begin drilling operations.

If the minimum subscription proceeds are not received by the offering
termination date of a partnership, then the sums deposited in the escrow account
will be promptly returned to you and the other subscribers in that partnership
with interest and without deduction for any fees. In this regard, the latest
offering termination date for each of the partnerships is December 31, 2006.
Although the managing general partner and its affiliates may buy up to 5% of the
units in each partnership, currently they do not anticipate purchasing any
units. If they do buy units, then those units will not be applied towards the
minimum subscription proceeds required for a partnership to break escrow and
begin operations. Also, any purchases of units by the managing general partner
and its affiliates must be made for investment purposes only, and not with a
view toward redistribution.

You will receive interest on your subscription proceeds from the time they are
deposited in the escrow account, or the partnership account if you subscribe
after the minimum subscription proceeds have been received and escrow has been
broken, until the final closing of the partnership to which you subscribed. The
interest will be paid to you not later than your partnership's first cash
distribution from operations.

                                       37


During each partnership's escrow period its subscription proceeds will be
invested only in institutional investments comprised of or secured by securities
of the United States government. After the funds are transferred to a
partnership account and before their use in partnership operations, they may be
temporarily invested in income producing short-term, highly liquid investments,
in which there is appropriate safety of principal, such as U.S. Treasury Bills.
If the managing general partner determines that a partnership may be deemed to
be an investment company under the Investment Company Act of 1940, then the
investment activity will cease. Subscription proceeds will not be commingled
with the funds of the managing general partner or its affiliates, nor will
subscription proceeds be subject to their creditors' claims before they are paid
to the managing general partner under the drilling and operating agreement.

ACCEPTANCE OF SUBSCRIPTIONS
Your execution of the subscription agreement constitutes your offer to buy units
in the partnership then being offered and to hold the offer open until either:

     o    your subscription is accepted or rejected by the managing general
          partner; or

     o    you withdraw your offer.

To rescind or withdraw your subscription agreement, you must give written notice
to the managing general partner before your subscription agreement is accepted
by the managing general partner.

Also, the managing general partner will:

     o    not complete a sale of units to you until at least five business days
          after the date you receive a final prospectus; and

     o    send you a confirmation of purchase.

Subject to the foregoing, your subscription agreement will be accepted or
rejected by the partnership within 30 days of its receipt. The managing general
partner's acceptance of your subscription is discretionary, and the managing
general partner may reject your subscription for any reason without incurring
any liability to you for this decision. If your subscription is rejected, then
all of your funds will be promptly returned to you together with any interest
earned on your subscription proceeds.

When you will be admitted to a partnership depends on whether your subscription
is accepted before or after breaking escrow. If your subscription is accepted:

     o    before breaking escrow, then you will be admitted to the partnership
          to which you subscribed not later than 15 days after the release from
          escrow of the investors' funds to that partnership; or

     o    after breaking escrow, then you will be admitted to the partnership to
          which you subscribed not later than the last day of the calendar month
          in which your subscription was accepted by that partnership.

Your execution of the subscription agreement and the managing general partner's
acceptance also constitutes your:

     o    execution of the partnership agreement and agreement to be bound by
          its terms as a partner; and

SUITABILITY STANDARDS

IN GENERAL. It is the obligation of persons selling the units to make every
reasonable effort to assure that the units are suitable for you based on your
investment objectives and financial situation, regardless of your income or net
worth. However, you should invest in a partnership only if you are willing to
assume the risk of a speculative, illiquid, and long-term investment. Also,
subscriptions to a partnership will not be accepted from IRAs, Keogh plans and
qualified retirement plans because the partnership's income would be
characterized as unrelated business taxable income, which is subject to federal
income tax.

The decision to accept or reject your subscription will be made by the managing
general partner, in its sole discretion, and is final. The managing general
partner will not accept your subscription until it has reviewed your apparent
qualifications, and the suitability determination must be maintained by the
managing general partner during the partnership's term and for at least six
years thereafter.

(1) A "gross well" is one in which a leasehold interest is owned.
(2) A "net well" equals the actual leasehold interest owned in one gross well
    divided by one hundred. For example, a 50% leasehold interest in a well is
    one gross well, but a .50 net well.
(3) For purposes of this Table only, a "Dry Hole" means a well which is plugged
    and abandoned with or without a completion attempt because the operator has
    determined that it will not be productive of gas and/or oil in commercial
    quantities.

(1) All cash distributions were from the sale of gas, except that the following
    partnerships also include revenue from the sale of properties: A.E.
    Nineties-16($4,776), A.E. Nineties-19($1,607), Atlas America Series
    # 20($6,213), A.E. Nineties-Public # 1($2,453), A.E. Nineties-Public
    # 2($3,292), A.E. Nineties-Public # 3($2,491), A.E. Nineties-Public
    # 5($8,639), A.E. Nineties-Public #7($2,296) and Atlas America Public
    # 11($2,789).
(2) A portion of the cash distributions was used to drill three reinvestment
    wells at a cost of $307,434 in accordance with the terms of the offering.
(3) This column reflects total cash distributions beginning with the first
    production from the program as a percentage of the total amount invested in
    the program and includes the return of the investors' capital.
(4) As of the date of this table there is not twelve months of production and/or
    not all of the wells are drilled or on-line to sell production.
(5) Operating costs consist of gathering fees, water hauling fees, meter reading
    fees, repairs and maintenance, insurance and severance tax.
(6) Current reserve information is not available for these partnerships. The
    most current reserve report is dated 1/1/05. Also, reserve information for
    Public #15-2005(A), which closed at 12/31/05, is incomplete since not all of
    its wells were drilled at 1/1/06.
(7) The information presented in this column has been prepared in conformity
    with SEC guidelines by making the standardized estimates of future net cash
    flow from proved reserves using natural gas and oil prices in effect as of
    the date of the estimates, which was a weighted average price of $10.08 per
    mcf for the natural gas, and which are held constant throughout the life of
    the properties. The information presented for future net cash flows based on
    estimated proved reserves has been prepared by the managing general
    partner's petroleum engineers and reviewed by an independent petroleum
    consultant, Wright & Company, Inc., as noted below with respect to the
    managing general partner's prior public partnerships: Atlas-Energy for the
    Nineties-Public #1 Ltd., Atlas-Energy for the Nineties-Public #2 Ltd.,
    Atlas-Energy for the Nineties-Public #3 Ltd., Atlas-Energy for the

    America Public #9 Ltd., Atlas America Public #10 Ltd., Atlas America Public
    #11-2002 Ltd., Atlas America Public #12-2003 Limited Partnership, Atlas
    America Series 25-2004(A) L.P., Atlas America Series 25-2004(B) L.P., Atlas
    America Public #14-2004 L.P., Atlas America Public #14-2005(A) L.P., Atlas
    America Series 26-2005 L.P., and Atlas America Public #15-2005(A) L.P. The
    other partnerships have not been reviewed by Wright & Company, Inc. You
    should understand that reserve estimates are imprecise and may change. There
    are inherent uncertainties in interpreting the engineering data and the
    projection of future rates of production. Also, prices received from the
    sale of natural gas and oil may be different from those estimated in
    preparing the reports, and the amounts and timing of future operating and
    development costs may also differ from those used in preparing the reports.
    The cash flow information based on estimated proved reserves shown for a
    partnership does not include this information for the managing general
    partner.
(8) This column represents a partnership's estimate of future net cash flows
    from its proved reserves using natural gas sales prices in effect as of the
    dates of the estimates which are held constant throughout the life of the
    partnership's properties. As natural gas prices change, these estimates will
    change. The information in this column has not been discounted.
(9) This column represents a partnership's estimate of future net cash flows
    from its proved reserves using natural gas sales prices in effect as of the
    dates of the estimates which are held constant throughout the life of the
    partnership's properties. As natural gas prices change, these estimates will
    change. The present value of estimated future net cash flows is calculated
    by discounting estimated future net cash flows by 10% annually in accordance
    with SEC guidelines. You should not construe the estimated PV-10 values as
    representative of the fair market value of a partnership's properties.

(1) These columns reflect the savings in taxes which would have been paid by an
    investor, assuming full use of deductions available to the investor.
(2) Atlas Resources anticipates that approximately 90% of an investor general
    partner's subscription to a partnership will be deductible in the year in
    which he invests.
(3) The I.D.C. Deductions, Depletion Allowance and MACRS depreciation deductions
    have been reduced to credit equivalents.
(4) The Section 29 tax credit is not available with respect to wells drilled
    after December 31, 1992. N/A means not applicable.
(5) These distributions were all from production revenues, except that the
    following partnerships also include revenue from the sale of properties:

    ($8,639), A.E. Nineties-Public # 7 ($2,296) and Atlas America Public # 11
    ($2,789).
(6) This column reflects total cash distributions beginning with the first
    production from the program and includes the return of investor's capital.
(7) These percentages are calculated by dividing the entry for each partnership
    in the "Total Cash Dist. And Tax Savings" column by that partnership 's
    entry in the "Investor Capital" column.
(8) As of the date of this table there is not twelve months of production and/or
    not all wells are drilled or on-line to sell production.

                                   MANAGEMENT

MANAGING GENERAL PARTNER AND OPERATOR

The partnerships will have no officers, directors or employees. Instead, Atlas
Resources, LLC, a Pennsylvania limited liability company, which was originally
formed as a corporation in 1979 and then changed to a limited liability company
on March 28, 2006, will serve as the managing general partner of each
partnership. However, see "- Transactions with Management and Affiliates"
regarding the managing general partner's dependence on its parent company, Atlas
America, for management and administrative functions and financing for capital
expenditures. The managing general partner and its affiliates operate more than
5,100 natural gas and oil wells located in Ohio, Pennsylvania, New York and
Tennessee.

In addition, Atlas America recently announced that it intends to transfer to a
newly-formed wholly-owned limited liability company or limited partnership
subsidiary of Atlas America substantially all of its natural gas and oil
exploration and production assets, and make a registered initial public offering
of a minority interest, estimated to be 20%, in the newly-formed subsidiary.
This prospectus does not constitute an offer to sell or a solicitation of an
offer to buy any such securities. Rather than transferring those energy assets
directly to its newly-formed subsidiary, which Atlas America anticipates will be
a Pennsylvania limited liability company named "Atlas Energy, LLC," Atlas
America intends to make Atlas Energy, LLC the indirect owner of the energy
assets by changing the Atlas America subsidiaries that currently own those
assets, including the managing general partner, into limited liability company
subsidiaries of Atlas Energy, LLC, and liquidating certain inactive subsidiaries
of Atlas America. Atlas America anticipates that all of these transactions will
be completed sometime during 2006 and before or upon the closing of the intended
public offering of interests in Atlas Energy, LLC discussed above. The
anticipated effect of Atlas America's intended transactions in connection with
Atlas Energy, LLC can be seen by comparing the "--Current Organizational
Diagram" with the "--Pro Forma Organizational Diagram (Subject to Change)" in
"--Organizational Diagrams and Security Ownership of Beneficial Owners," below.

Since 1985 the managing general partner has sponsored 15 public and 36 private
partnerships to conduct natural gas drilling and development activities in
Pennsylvania, Ohio, New York and Tennessee. In these partnerships the managing
general partner and its affiliates acted as the operator and the general
drilling contractor and were responsible for drilling, completing, and operating
the wells. Atlas Resources has a 97% completion rate for wells drilled by its
development partnerships.

In September 1998, Atlas Energy Group, Inc., the former parent company of the
managing general partner, merged into Atlas America, Inc., a Delaware holding
company, which was a subsidiary of Resource America, Inc., a publicly-traded
company, which is sometimes referred to in this prospectus as Resource America.
In May 2004 Resource America conducted a public offering of a portion of its
common stock (the "shares") in Atlas America. Two million six hundred forty-five
thousand shares were registered and sold at a price of at $15.50 per share
resulting in gross proceeds of $41 million. Further, in May 2004, in connection
with the Atlas America offering, the following officers and key employees of the
managing general partner and Atlas America set forth in "- Officers, Directors
and Other Key Personnel," below, resigned their positions with Resource America
and all of its subsidiaries which are not also subsidiaries of Atlas America:
Mr. Freddie M. Kotek, Mr. Frank P. Carolas, Mr. Jeffrey C. Simmons, Ms. Nancy J.
McGurk, Mr. Michael L. Staines, and Ms. Marci Bleichmar.

After the public offering, Resource America continued to own approximately 80.2%
of Atlas America's common stock until it distributed all of its remaining 10.7
million shares of common stock in Atlas America to its common stockholders on
June 30, 2005. The distribution was in the form of a spin-off by means of a tax
free dividend of approximately 0.6 shares of Atlas America to Resource America
common stockholders for each share of Resource America common stock owned. As a
result of the spin-off, Resource America is no longer in a position to determine
the outcome of corporate actions requiring the approval of Atlas America's
stockholders, such as:

     o    the election and removal of directors;

     o    mergers or other business combinations involving Atlas America;

     o    future issuances of Atlas America's common stock or other securities;
          and

     o    amendments to Atlas America's certificate of incorporation and bylaws.

These actions will be passed on by Atlas America's stockholders existing at the
record dates for such matters. Resource America's rights following the
distribution are defined by agreements between Resource America and Atlas
America.

Atlas America is headquartered at 311 Rouser Road, Moon Township, Pennsylvania

general partner's primary office.

With respect to the biographical information set forth below:

     o    the approximate amount of an individual's professional time devoted to
          the business and affairs of the managing general partner and Atlas
          America have been aggregated because there is no reasonable method for
          them to distinguish their activities between the two companies; and

     o    for those individuals who also hold senior positions with other
          affiliates of the managing general partner, if it is stated that they
          devote approximately 100% of their professional time to the managing
          general partner and Atlas America, it is because either the other
          affiliates are not currently active in drilling new wells, such as
          Viking Resources or Resource Energy, and the individuals are not
          required to devote a material amount of their professional time to the
          affiliates, or there is no reasonable method to distinguish their
          activities between the managing general partner and Atlas America as
          compared with the other affiliates of the managing general partner,
          such as Viking Resources or Resource Energy.

subsidiaries to limited liability subsidiaries of Atlas Energy LLC, and
liquidating certain inactive corporate subsidiaries. The changes in the
following organizational diagram from the "- Current Organizational Diagram" set

transfer to a newly-formed subsidiary of Atlas America substantially all of its
natural gas and oil exploration and production assets. Atlas America anticipates
that all of these transactions will be completed before or upon the closing of
Atlas Energy, LLC's public offering as described in "- Managing General Partner

                                       56


CODE OF BUSINESS CONDUCT AND ETHICS

Because the partnerships do not directly employ any persons, the managing
general partner has determined that the partnerships will rely on a Code of
Business Conduct and Ethics adopted by Atlas America, Inc. that applies to the
principal executive officer, principal financial officer and principal
accounting officer of the managing general partner, as well as to persons
performing services for the managing general partner generally. You may obtain a
copy of this code of ethics by a request to the managing general partner at
Atlas Resources, LLC, 311 Rouser Road, Moon Township, Pennsylvania 15108.

TRANSACTIONS WITH MANAGEMENT AND AFFILIATES
The managing general partner depends on its parent company, Atlas America, for
management and administrative functions and financing for capital expenditures.
The managing general partner pays a management fee to Atlas America for
management and administrative services, which amounted to $45.7 million, $21.6
million, and $13.1 million for the years ended September 30, 2005, 2004, and
2003, respectively. (See "Financial Information Concerning the Managing General
Partner and Atlas America Public #15-2006(B) L.P.," including the indebtedness
owed by the managing general partner to Atlas America.)

The managing general partner and its officers, directors and affiliates have in
the past invested, and may in the future invest, in partnerships sponsored by
the managing general partner. They may also subscribe for units in each
partnership as described in "Plan of Distribution."

          MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION,
             RESULTS OF OPERATIONS, LIQUIDITY AND CAPITAL RESOURCES

Atlas America Public #15-2006(B) L.P. and Atlas America Public #15-2006(C) L.P.
have been formed as limited partnerships under the Delaware Revised Uniform
Limited Partnership Act. The partnerships, however, have not included any
historical information in this prospectus since they:

     o    have no net worth;

     o    do not own any properties on which wells will be drilled;

     o    have no third-party investors; and

     o    have not conducted any operations.

(See "Capitalization and Source of Funds and Use of Proceeds," "Proposed
Activities," "Competition, Markets and Regulation," and "Financial Information
Concerning the Managing General Partner and Atlas America Public #15-2006(B)
L.P.")

Each partnership will depend on the proceeds of this offering and the managing
general partner's capital contributions to carry out its proposed activities.
Each partnership intends to use its subscription proceeds to pay the intangible
drilling costs, the investors' share of equipment costs, and the investors'
share of any cost overruns of drilling and completing the partnership's wells.

The managing general partner believes that each partnership's liquidity
requirements will be satisfied from the following:

     o    subscription proceeds of this offering;

     o    the managing general partner's capital contributions;

     o    cash flow from future operations; and

                                       57


     o    partnership borrowings, if necessary.

The managing general partner also anticipates that no additional funds will be
required for operating costs before a partnership begins receiving production
revenues from its wells.

Substantially all of the subscription proceeds of you and the other investors in
a partnership will be committed or expended after the offering of the
partnership closes. If a partnership requires additional funds for cost overruns
or additional development or remedial work after a well begins producing, then
these funds may be provided by:

     o    subscription proceeds, if available, drilling fewer wells, or
          acquiring a lesser working interest in one or more wells;

     o    borrowings from the managing general partner or its affiliates; or

     o    retaining partnership revenues.

There will be no borrowings from third-parties. The amount that may be borrowed
by a partnership from the managing general partner and its affiliates may not at
any time exceed 5% of the partnership's subscription proceeds from you and the
other investors and must be without recourse to you and the other investors. The
partnership's repayment of any borrowings would be from partnership production
revenues and would reduce or delay your cash distributions.

If the managing general partner loans money to a partnership, which it is not
required to do, then:

     o    the interest charged to the partnership must not exceed the managing
          general partner's interest cost or the interest that would be charged
          to the partnership without reference to the managing general partner's
          financial abilities or guarantees by unrelated lenders, on comparable
          loans for the same purpose; and

     o    the managing general partner may not receive points or other financing
          charges or fees, although the actual amount of the charges incurred
          from third-party lenders may be reimbursed to the managing general
          partner.

As of the date of this prospectus, Atlas America (the "borrower") has a $75
million revolving credit facility with a group of banks with Wachovia Bank, N.A.
as the agent and issuing bank. The managing general partner and various energy
subsidiaries of Atlas America are guarantors of the credit agreement. As of
September 30, 2005, this facility had a borrowing base of $75 million.
Borrowings under the facility are collateralized by substantially all of the
assets of Atlas America, the managing general partner and the other guarantors.
This includes the managing general partner's interests in its partnerships, but
does not include any investor's interest in a partnership. A breach of the
credit agreement by the borrower is a default under the loan. The credit
facility's term ends in March 2007. At September 30, 2005, the borrower had an
outstanding balance of approximately $8 million and also had a $1.5 million
letter of credit issued under the facility.

The managing general partner depends on its parent company, Atlas America, for
management and administrative functions and financing for capital expenditures.
The managing general partner pays a management fee to Atlas America for
management and administrative services, as described in "Management -
Transactions with Management and Affiliates." See the footnotes to the managing
general partner's audited financial statements and the footnotes to the managing
general partner's unaudited financial statements for more details concerning the
credit facility and inter-company borrowings in "Financial Information
Concerning the Managing General Partner and Atlas America Public #15-2006(B)
L.P."

                               PROPOSED ACTIVITIES

OVERVIEW OF DRILLING ACTIVITIES
The managing general partner anticipates that the subscription proceeds of each
partnership will be used to drill primarily natural gas development wells, which
means a well drilled within the proved area of a natural gas or oil reservoir to
the depth of a stratigraphic horizon known to be productive. Stratigraphic means
a layer of rock which has characteristics that differentiate it from the rocks
above and below it. Stratigraphic horizon generally means that part of a
formation or layer of rock with sufficient porosity and permeability to form a
petroleum reservoir. Currently, the partnerships do not hold any interests in
any properties or prospects on which the wells will be drilled.

Although the majority of the wells to be drilled by each partnership will be
classified as natural gas wells, which may produce a small amount of oil, some
of the wells, such as wells drilled in McKean County, Pennsylvania, if any, may
be classified as oil or combination oil and natural gas wells.

Each partnership will be a separate business entity from the other partnerships,
and you will be a partner only in the partnership in which you invest. You will
have no interest in the business, assets or tax benefits of the other
partnerships unless you also invest in the other partnerships. Thus, your
investment return will depend solely on the operations and success or lack of
success of the particular partnership in which you invest.

Each partnership generally will drill different wells, but they may own working
interests and participate in drilling and completing one or more of the same
wells. The number of wells to be drilled by a partnership cannot be determined
precisely before the funding of the partnership and is determined primarily by:

     o    the amount of subscription proceeds raised by the partnership (for
          example, the targeted maximum subscription proceeds for Atlas America
          Public #15-2006(B) L.P. are $125 million, as contrasted with the
          targeted maximum subscription proceeds of only $22.726 million for
          Atlas America Public #15-2006(C) L.P.;

     o    the geographical areas in which wells are drilled by the partnership;

     o    the partnership's percentage of working interest owned in the wells,
          which could range from 25% to 100%; and

     o    the cost of the partnership's wells, including any cost overruns for
          intangible drilling costs and equipment costs of the wells which are
          charged to you and the other investors under the partnership
          agreement.

For the estimated number of wells to be drilled at the minimum subscription
proceeds of $2 million and the maximum subscription proceeds of $147,726,000 for
a partnership, see "Risk Factors - Risks Related to an Investment in a
Partnership - Spreading the Risks of Drilling Among a Number of Wells Will be
Reduced if Less than the Maximum Subscription Proceeds are Received and Fewer
Wells are Drilled."

Before the managing general partner selects a prospect on which a well will be
drilled by a partnership, it will review all available geologic and production
data for wells located in the vicinity of the proposed well including, but not
limited to:

     o    various well logs;

     o    completion reports;

     o    plugging reports; and

     o    production reports.

                                       59


For example, production information from surrounding wells in the area is an
important indicator in evaluating the economic potential of a proposed well to
be drilled. It has been the managing general partner's experience that natural
gas production from wells drilled to the formations or the reservoirs in the
areas of operations discussed below in "- Primary Areas of Operations," is
reasonably consistent with nearby wells, although from time to time there can be
great differences in the natural gas volumes and performance of wells located on
contiguous prospects. However, production information is only one factor and the
managing general partner may propose a well to be drilled by a partnership
because geologic trends in the immediate area, such as sand thickness,
porosities and water saturations, lead the managing general partner to believe
that the proposed well locations will be productive.

PRIMARY AREAS OF OPERATIONS
The managing general partner will not decide on all of the specific wells to be
drilled by a partnership until the offering of units in that partnership has
ended. However, the managing general partner intends that Atlas America Public
#15-2006(B) L.P. will drill the prospects described in "Appendix A - Information
Regarding Currently Proposed Prospects for Atlas America Public #15-2006(B)
L.P." These prospects represent the wells to be drilled if a portion of the
nonbinding targeted subscription proceeds for that partnership, as described in
"Terms of the Offering - Subscription to a Partnership," are received. If there
are adverse events with respect to any of the currently proposed prospects, the
managing general partner will substitute the partnership's prospects as
discussed below in "- Interests of Parties." Also, the managing general partner
has the sole discretion to sell up to and including all of the remaining units
in Atlas America Public #15-2006(B) L.P., and it may and not offer and sell any
units in Atlas America Public #15-2006(C) L.P. In that event, the number of
prospects identified in "Appendix A - Information Regarding Currently Proposed
Prospects for Atlas America Public #15-2006(B) L.P." as a percentage of the
total number of prospects to be drilled by Atlas America Public #15-2006(B) L.P.
would be reduced. The managing general partner also anticipates that it will
designate a portion of the prospects in the partnership designated Atlas America
Public #15-2006(C) L.P., if units in that partnership are offered, by a
supplement or an amendment to the registration statement of which this
prospectus is a part.

Because not all of the prospects for each partnership will be specified, you
will not be able to evaluate some, or even the majority, of the specific
prospects that will be drilled by your partnership. However, by waiting as long
as possible before selecting all of the specific prospects to be drilled by a
partnership, the managing general partner may acquire additional information to
help it select better prospects for the partnership, and it may be able to
include prospects which were not available when this prospectus was written or
even when the offering of units in the partnership is closed.

The following discussion includes a general description of the areas where the
managing general partner anticipates partnership wells may be drilled. With
respect to each area listed below, the geological aspects are continually being
evaluated by the managing general partner. Thus, each area discussed may
ultimately include other counties which are not set forth below. For purposes of
this prospectus, however, the counties listed are generally descriptive of the
specific drilling area being discussed. With the exception of the north central
Tennessee area, the primary areas are situated in western Pennsylvania as
discussed below. The three primary areas for the partnerships' drilling
activities are:

     o    the Mississippian/Upper Devonian Sandstone reservoirs in Fayette,
          Greene and Westmoreland Counties, Pennsylvania;

     o    the Clinton/Medina geological formation which includes western
          Pennsylvania, primarily Crawford and Mercer Counties, Pennsylvania and
          also includes an area in eastern Ohio primarily in Stark, Mahoning,
          Trumbull and Portage Counties; and

     o    the Mississippian (carbonates) and Devonian Shale reservoirs in
          Anderson, Campbell, Morgan, Roane and Scott Counties, Tennessee.

All of the primary areas described above have the following similarities:

     o    geological features such as structure and faulting are not generally
          factors used in finding commercial production from a well drilled to
          this formation or these reservoirs and the governing factors appear to
          be sand or oolite (carbonate sand) quality in terms of net pay zone
          thickness, porosity, and the effectiveness of fracture stimulation;

                                       60


     o    a well drilled to this formation or these reservoirs usually requires
          hydraulic fracturing of the formation to stimulate productive
          capacity;

     o    generally, natural gas from a well drilled to this formation or these
          reservoirs is produced at rates which decline rapidly during the first
          few years of operations, and although the well can produce for many
          years, a proportionately larger amount of production can be expected
          within the first several years; and

     o    it has been the managing general partner's experience that natural gas
          production from wells drilled to this formation or these reservoirs is
          reasonably consistent with nearby wells, although from time to time
          there can be great differences in the natural gas volumes and
          performance of wells on contiguous prospects.

The managing general partner anticipates that the majority of the subscription
proceeds of each partnership will be expended in the primary areas, although
some of the subscription proceeds of each partnership may be expended in the
secondary areas or in areas which are not currently known. Among the primary
areas, the managing general partner anticipates that each partnership will drill
more prospects in the Fayette County area than in the other areas.

MISSISSIPPIAN/UPPER DEVONIAN SANDSTONE RESERVOIRS, FAYETTE COUNTY, PENNSYLVANIA.
The Mississippian/Upper Devonian Sandstone reservoirs are discontinuous
lens-shaped accumulations found throughout most of the Appalachian Basin. These
reservoirs have porosities ranging from 5% to 20% with attendant permeabilities.
Porosity is the percentage of void space between sand grains that is available
for occupancy by either liquids or gases; and permeability is the property of
porous rock that allows fluids or gas to flow through it. See the geologic
evaluation prepared by United Energy Development Consultants, Inc., an
independent geological and engineering firm, for a discussion of the development
of the Mississippian/Upper Devonian Sandstone reservoirs in Fayette, Greene and
Westmoreland Counties, Pennsylvania.

The wells in the Mississippian/Upper Devonian Sandstone reservoirs will be:

     o    situated on approximately 20 acres, subject to adjustment to take into
          account lease boundaries;

     o    drilled at least 1,000 feet from a producing well, although a
          partnership may drill a new well or re-enter an existing well which is
          closer than 1,000 feet to a plugged and abandoned well;

     o    drilled from approximately 1,900 to 5,500 feet in depth;

     o    classified as natural gas wells which may produce a small amount of
          oil; and

     o    primarily connected to the gathering system owned by Atlas Pipeline
          Partners and have their natural gas production primarily marketed to
          UGI Energy Services as described below in "- Sale of Natural Gas and
          Oil Production" until March 31, 2007.

CLINTON/MEDINA GEOLOGICAL FORMATION IN WESTERN PENNSYLVANIA. The Clinton/Medina
geological formation is a blanket sandstone found throughout most of the
northwestern edge of the Appalachian Basin. The Clinton/Medina geological
formation in Pennsylvania and Ohio is the same geological formation, although in
Pennsylvania it is often referred to as the Medina/Whirlpool geological
formation. For purposes of this prospectus, the term Clinton/Medina geological
formation is used for both Ohio and Pennsylvania. The Clinton/Medina is
described in petroleum industry terms as a "tight" sandstone with porosity
ranging from 6% to 12% and with very low natural permeability. Based on the
managing general partner's experience, it anticipates that all of the natural
gas wells drilled to the Clinton/Medina will be completed and fraced in two
different zones of the Clinton/Medina geological feature. See the geologic
evaluation and the model decline curve prepared by United Energy Development
Consultants, Inc. in "Appendix A - Information Regarding Currently Proposed
Prospects for Atlas America Public #15-2006(B) L.P." for a discussion of the
development of the Clinton/Medina Geological Formation in western Pennsylvania
and eastern Ohio.


                                       61


The wells in the Clinton/Medina geological formation in western Pennsylvania and
eastern Ohio will be:

     o    primarily situated in Crawford, Mercer, Lawrence, Warren, and Venango
          Counties, Pennsylvania, and Stark, Mahoning, Trumbull and Portage
          Counties, Ohio;

     o    situated on approximately 50 acres, subject to adjustment to take into
          account lease boundaries;

     o    drilled at least 1,650 feet from each other in Pennsylvania, which is
          greater than the 660 feet minimum distance allowed by state law or
          local practice to protect against drainage from adjacent wells, and
          drilled at least 1,000 feet from each other in Ohio;

     o    drilled from approximately 5,100 to 6,300 feet in depth;

     o    classified as natural gas wells which may produce a small amount of
          oil, although the wells in eastern Ohio may be classified as oil
          wells; and

     o    primarily connected to the gathering system owned by Atlas Pipeline
          Partners and have their natural gas production primarily marketed to
          Amerada Hess Corporation as described below in "- Sale of Natural Gas
          and Oil Production".

Also, see "- Secondary Areas of Operations" below, for a discussion of the
Clinton/Medina geological formation in western New York and southern Ohio.

MISSISSIPPIAN CARBONATE AND DEVONIAN SHALE RESERVOIRS IN ANDERSON, CAMPBELL,
MORGAN, ROANE AND SCOTT COUNTIES, Tennessee. The Mississippian carbonate
reservoirs are discontinuous lens shaped accumulations found in the southern
Appalachian states of West Virginia, Virginia, Kentucky and Tennessee. These
reservoirs have porosities ranging from 6% to 20% with attendant permeabilities.
The Devonian shale is found throughout the Appalachian Basin. When the shale is
highly fractured it becomes a reservoir. See the geologic evaluation prepared by
United Energy Development Consultants, Inc. in "Appendix A - Information
Regarding Currently Proposed Prospects for Atlas America Public #15-2006(B)
L.P." for a discussion of the development of the Mississippian carbonate and
Devonian Shale reservoirs in Anderson, Campbell, Morgan, Roane and Scott
Counties, Tennessee.

The wells in the Mississippian carbonate and Devonian Shale reservoirs will be:

     o    situated on 40 acres;

     o    drilled 1,320 feet from each other unless topography dictates
          otherwise, however, in all cases no less than 700 feet;

     o    drilled from approximately 2,000 to 4,600 feet in depth;

     o    classified as natural gas wells which may produce a small amount of
          oil; and

     o    primarily connected to the gathering system owned by Knox Energy LLC,
          which is referred to as the Coalfield Pipeline, and have their natural
          gas production primarily marketed to Duke Energy as described below in
          "- Sale of Natural Gas and Oil Production."

The prospects in Anderson, Campbell, Morgan, Roane and Scott Counties, Tennessee
were acquired from Knox Energy LLC as described below in "- Interests of
Parties" and Knox Energy may participate in the drilling of the wells with the
partnership.

                                       62

SECONDARY AREAS OF OPERATIONS
The managing general partner also has reserved the right to use a portion of the
subscription proceeds of each partnership to drill development wells in other
areas of the Appalachian Basin or elsewhere in the United States. The secondary
areas anticipated by the managing general partner, which are situated in the
Appalachian Basin, are discussed below.

UPPER DEVONIAN SANDSTONE RESERVOIRS, ARMSTRONG COUNTY, PENNSYLVANIA. The Upper
Devonian Sandstone reservoirs are discontinuous lens-shaped accumulations found
throughout most of the Appalachian Basin. These reservoirs have porosities
ranging from greater than 5% to 20% with attendant permeabilities. The prospects
in Armstrong and Indiana Counties, Pennsylvania will be acquired from U.S.
Energy Exploration Corporation as described below and U.S. Energy will
participate in the drilling of the wells with the partnerships.

The wells in the Upper Devonian Sandstone reservoirs will be:

     o    situated on approximately 15 acres, subject to adjustment to take into
          account lease boundaries;

     o    drilled at least 1,000 feet from each other, although under
          Pennsylvania law in certain circumstances a variance can be obtained,
          and some of the wells the managing general partner has drilled to date
          in this general area have been drilled less than 1,000 feet apart, but
          even in those cases the wells were approximately 980 feet or more from
          each other;

     o    drilled from approximately 1,800 to 4,400 feet in depth;

     o    classified as natural gas wells which may produce a small amount of
          oil; and

     o    connected to a gathering system owned by U.S. Energy and have their
          natural gas production marketed by U.S. Energy as described below in
          "- Sale of Natural Gas and Oil Production."

The managing general partner anticipates the leases in Armstrong and Indiana
Counties, Pennsylvania will have a net revenue interest to a partnership of
84.375%. U.S. Energy, the originator of the leases, however, will retain a 25%
working interest in the wells and participate with the partnership in the costs
of drilling, completing, and operating the wells to the extent of its retained
working interest.

UPPER DEVONIAN SANDSTONE RESERVOIRS IN MCKEAN COUNTY, PENNSYLVANIA. See "- Upper
Devonian Sandstone Reservoirs, Armstrong County, Pennsylvania," above, for a
description of these reservoirs. Wells located in McKean County and drilled to
the Upper Devonian Sandstone reservoirs will be:

     o    situated on approximately 5 acres subject to adjustments to take into
          account lease boundaries;

     o    drilled from approximately 2,000 to 2,500 feet in depth;

     o    classified as combination wells producing both natural gas and oil;

     o    drilled on leases with a net revenue interest of approximately 87.5%;
          and

     o    connected to the gathering systems owned by Atlas Pipeline Partners
          and M&M Royalty, LTD. and have their natural gas production primarily
          marketed to M&M Royalty, LTD. as described below in "- Sale of Natural
          Gas and Oil Production."

CLINTON/MEDINA GEOLOGICAL FORMATION IN WESTERN NEW YORK. Wells located in
western New York and drilled to the Clinton/Medina geological formation will be:

     o    primarily situated in Chautauqua County;

     o    situated on approximately 40 acres, subject to adjustment to take into
          account lease boundaries;

     o    drilled from approximately 3,800 to 4,000 feet in depth;

     o    drilled on leases with a net revenue interest of approximately 84.375%
          to 87.5%;

     o    classified as natural gas wells which may produce a small amount of
          oil; and

     o    connected to the gathering system owned by Atlas Pipeline Partners and
          have their natural gas production primarily marketed to Amerada Hess
          Corporation, commercial end users in the area, and/or Great Lakes
          Energy Partners, L.L.C. as described below in "- Sale of Natural Gas
          and Oil Production."

CLINTON/MEDINA GEOLOGICAL FORMATION IN SOUTHERN OHIO. Wells located in southern
Ohio and drilled to the Clinton/Medina geological formation will be:

     o    primarily situated in Noble, Washington, Guernsey, and Muskingum
          Counties;

                                       63


     o    situated on approximately 40 acres, subject to adjustment to take into
          account lease boundaries;

     o    drilled at least 1,000 feet from each other;

     o    drilled from approximately 4,900 to 6,500 feet in depth;

     o    drilled on leases with a net revenue interest of approximately 82.5%
          to 87.5%;

     o    classified as either natural gas wells or oil wells; and

     o    primarily connected to the gathering system owned by Atlas Pipeline
          Partners (if classified as natural gas wells) and have their natural
          gas production marketed to Amerada Hess Corporation, although a
          portion of the natural gas production may be gathered and marketed by
          Triad Energy Corporation of West Virginia, Inc. as described below in
          "- Sale of Natural Gas and Oil Production."

Additionally, the managing general partner anticipates that the leases in
southern Ohio will have been originally acquired from a coal company and are
subject to a provision that the well must be abandoned if it hinders the
development of the coal. Thus, the managing general partner will not drill a
well on any lease subject to this provision unless it covers lands that were
previously mined. Although this does not totally eliminate the risk because the
leases may cover other coal deposits that might be mined during the life of a
well, the managing general partner believes that drilling wells on these
previously mined leases would be in the best interests of the partnerships.

ACQUISITION OF LEASES
The managing general partner will have the right, in its sole discretion, to
select the prospects which each partnership will drill. The managing general
partner intends that Atlas America Public #15-2006(B) L.P. will drill the
prospects described in "Appendix A - Information Regarding Currently Proposed
Prospects for Atlas America Public #15-2006(B) L.P." The managing general
partner also anticipates that it will designate a portion of the prospects in
Atlas America Public #15-2006(C) L.P., if units in that partnership are offered,
by means of a supplement or an amendment to the registration statement of which
this supplement is a part.

The leases covering each prospect on which one well will be drilled will be
acquired by a partnership from the managing general partner or its affiliates
and credited to the managing general partner as a part of its required capital
contribution to the partnership. Neither the managing general partner nor its
affiliates will receive any royalty or overriding royalty interest on any well.

                                       64


The managing general partner anticipates that it will select the prospects for
each partnership, including any additional and/or substituted prospects, from
the following:

     o    leases in its and its affiliates' existing leasehold inventory;

     o    leases that are subsequently acquired by it or its affiliates; or

     o    leases owned by independent third-parties that may participate with
          the partnership in drilling wells.

The majority of the prospects acquired by a partnership will be in areas where
the managing general partner or its affiliates have previously conducted
drilling operations. The managing general partner believes that its and its
affiliates' leasehold inventory and leases acquired from third-parties will be
sufficient to provide all the development prospects to be drilled by Atlas
America Public #15-2006(B) L.P. if it receives its targeted maximum subscription
proceeds of $125 million. With respect to the partnerships designated Atlas
America Public #15-2006(C) L.P., if units in that partnership are offered, the
managing general partner and its affiliates are continually engaged in acquiring
additional leasehold acreage in Pennsylvania, Ohio, and other areas of the
United States. Thus, the managing general partner believes that it will have a
sufficient number of development prospects for that partnership if it receives
its targeted maximum subscription proceeds of $22.726 million. As of December
31, 2005, the managing general partner's and its affiliates' undeveloped
leasehold acreage was as follows:

(1)  The net acreage as to which leases expire in fiscal 2006 and 2007 are as
     follows: New York: 2006 - 276 acres and 2007 - 10 acres; Ohio: 2006 - none
     and 2007 - 1,741 acres; Pennsylvania: 2006 - 14,079 acres and 2007 - 14,562
     acres.

Most, if not all, of the prospects to be selected for the partnerships are
expected by the managing general partner to be single well proved undeveloped
prospects which are classified as developmental. Thus, only one well will be
drilled on each of those prospects and the number of prospects the managing
general partner will assign to each partnership will be the same as the number
of wells which the partnership has the funds to drill. This also means that the
partnership, in all likelihood, will not farmout any acreage associated with
those prospects. However, the need for a farmout might arise, for example, if
during drilling or subsequently the managing general partner determines there
might be a productive horizon situated above (i.e. uphole) the target horizon,
but the partnership does not have the funds to complete the well in the horizon
or the completion of the horizon would be inconsistent with the partnership's
objectives. In this event, the managing general partner might decide to farmout
the activity for the partnership. Generally, a farmout is an agreement in which
the owner of the lease or existing well agrees to assign its interest in certain
acreage under the lease or the existing well to an assignee subject to the
assignee drilling one or more wells or completing or recompleting the existing
well in one or more horizons. The owner would retain some interest in the
assigned acreage or well. See "Conflicts of Interest - Conflicts Involving the
Acquisition of Leases" for the procedure for a farmout, and "Federal Income Tax
Consequences - Farmouts."

DEEP DRILLING RIGHTS RETAINED BY MANAGING GENERAL PARTNER. The lease assignments
to each partnership generally will be limited to a depth of from the surface to
the deepest depth penetrated at the cessation of drilling operations. The
managing general partner will retain the deeper drilling rights, including
ownership of any coal bed methane production that might be obtained from the
deeper formations. Conversely, as between a partnership and the managing general
partner, the partnership will own any coal bed methane production that might be
obtained from the shallower formations that are not included in the deeper
drilling rights retained by the managing general partner.

The amount of the credit the managing general partner receives for the leases it
contributes to a partnership will not include any value allocable to the deeper
drilling rights retained by it. If the managing general partner undertakes any
activities with respect to the deeper formations in the future, then the
partnerships would not share in the profits from these activities, nor would
they pay any of the associated costs.

INTERESTS OF PARTIES
Generally, production and revenues from a well drilled by a partnership will be
net of the applicable landowner's royalty interest, which is typically 1/8th
(12.5%) of gross production, and any interest in favor of third-parties such as
an overriding royalty interest. Landowner's royalty interest generally means an
interest that is created in favor of the landowner when an oil and gas lease is
obtained; and overriding royalty interest generally means an interest that is
created in favor of someone other than the landowner. In either case, the owner
of the interest receives a specific percentage of the natural gas and oil
production free and clear of all costs of development, operation, or maintenance
of the well. This is compared with a working interest, which generally means an
interest in the lease under which the owner of the interest must pay some
portion of the cost of development, operation, or maintenance of the well. Also,
the leases will be subject to terms that are customary in the industry such as
free gas to the landowner-lessor for home heating requirements, etc.

The managing general partner anticipates that each partnership generally will
have a net revenue interest in its leases in its primary drilling areas as set
forth in the chart below. Net revenue interest generally means the percentage of
revenues the owner of an interest in a well is entitled to receive under the
lease. The following chart expresses the percentage of production revenues that
the managing general partner, the landowner, other third-parties, and you and
the other investors in a partnership will share in from the wells in two of the
three primary drilling areas. The third primary drilling area in Anderson,
Campbell, Morgan, Roane and Scott Counties, Tennessee is discussed following the
chart. The chart assumes that the partnership owns 100% of the working interest
in the well. If a partnership acquires a lesser percentage working interest in a
well, which may be the case in Anderson, Campbell, Morgan, Roane and Scott
Counties, Tennessee, then the partnership's net revenue interest in that well
will decrease proportionately.

The actual number, identity and percentage of working interests or other
interests in prospects to be acquired by the partnerships will depend on, among
other things:

     o    the amount of subscription proceeds received in a partnership;

     o    the latest geological and production data;

     o    potential title or spacing problems;

     o    availability and price of drilling services, tubular goods and
          services;

     o    approvals by federal and state departments or agencies;

     o    agreements with other working interest owners in the prospects;

     o    farmins and farmouts; and

     o    continuing review of other prospects that may be available.

- ----------
(1)  These percentages are for illustration purposes only, and assume that the
     partnership has a 100% working interest and the managing general partner
     contributes its minimum required capital contribution of 25% to each
     partnership and the capital contributions from you and the other investors
     are 75%. The actual percentages are likely to be different because they
     will be based on the actual capital contributions of the managing general
     partner and you and the other investors. However, the managing general
     partner's total revenue share may not exceed 40% of partnership revenues
     regardless of the amount of its capital contributions.
(2)  It is anticipated that the majority of the wells in the Clinton/Medina
     Geological formation in Western Pennsylvania will have a net revenue
     interest of 85.9375% which, using the assumption in footnote (1), would
     provide investors as a group 58.44% of that partnerships' revenues from
     those wells. It is further possible that the wells could have a net revenue
     interest to a partnership as low as 84.375% which would reduce the
     investors' interest to 57.375% assuming that the managing general partner's
     capital contribution is 25% of that partnership's total capital
     contributions, which means that the investors as a group receive 68% of
     that partnership's revenues.

MISSISSIPPIAN CARBONATE AND DEVONIAN SHALE RESERVOIRS IN ANDERSON, CAMPBELL,
MORGAN, ROANE AND SCOTT COUNTIES, TENNESSEE. Generally, the leases in north
central Tennessee will have a net revenue interest to a partnership ranging from
84.375% to 81.375%, assuming that a partnership has a 100% working interest.
Whether the amount of the partnership's net revenue interest in some of the
prospects will be as low as 81.375% depends primarily on whether the landowner
royalty interest is 12.5% or 15.5%, which in turn depends on whether the natural
gas produced from those prospects, if any, is sold at a price above or below
$3.00 per mcf, and on whether Knox Energy LLC and its affiliates, the
originators of the leases, participate as a working interest owner in the leases
covering those prospects. Knox Energy and its affiliates may retain up to a 50%
working interest in the wells and participate with the partnership in the costs
of drilling, completing, and operating the wells to the extent of its retained
working interest. If Knox Energy does not retain a working interest in a well,
then its overriding royalty interest will be 3.125%. However, if Knox Energy
retains a 50% working interest in a well, then its overriding royalty interest
of 3.125% will be reduced to 1.5625%. To the extent that Knox Energy
participates in a well as a working interest owner for less than a 50% working
interest, the overriding royalty interest to Knox Energy will be prorated
between an overriding royalty interest of 3.125% and 1.5625%. The investors' net
revenue interest in the above example would range from 57.375% to 55.335% if
presented on a 100% working interest basis and the investors were receiving 68%
of the partnership revenues.

Pursuant to the acquisition terms between the managing general partner and its
affiliates and Knox Energy and its affiliates, no well drilled by the managing
general partner and its affiliates in this area may produce coalbed methane gas,
and the managing general partner or its affiliates must drill 300 commitment
wells during the initial three year term of the agreement with Knox Energy or it
is a breach of the agreement.

SECONDARY AREAS. Although the managing general partner anticipates that each
partnership will have a net revenue interest ranging from 81% to 87.5% in its
leases in the secondary areas described above, assuming 100% of the working
interest, there is no minimum net revenue interest that a partnership is
required to own before drilling a well in other areas of the United States. The
leases in these other areas may be subject to interests in favor of
third-parties that are not currently known such as overriding royalty interests,
net profits interests, carried interests, production payments, reversionary
interests pursuant to farmouts or non-consent elections under joint operating
agreements, or other retained or carried interests.

                                       67


TITLE TO PROPERTIES
Title to all leases acquired by a partnership ultimately will be held in the
name of the partnership. However, to facilitate the acquisition of the leases
title to the leases may initially be held in the name of the managing general
partner, the operator, their affiliates, or any nominee designated by the
managing general partner. Title to each partnership's leases will be transferred
to the partnership and filed for record from time to time after the wells are
drilled and completed.

The managing general partner will take the steps it deems necessary to assure
that each partnership has acceptable title for its purposes. However, it is not
the practice in the natural gas and oil industry to warrant title or obtain
title insurance on leases and the managing general partner will provide neither
for the leases it assigns to a partnership. The managing general partner will
obtain a favorable formal title opinion for the leases before each well is
drilled, but will not obtain a division order title opinion after the well is
completed. The managing general partner may use its own judgment in waiving
title requirements and will not be liable for any failure of title of leases
transferred to a partnership. Also, there is no assurance that the partnerships
will not experience losses from title defects excluded from or not disclosed by
the formal title opinion or that would have been disclosed by a division order
title opinion. Although past performance is no guarantee of future results, the
previous partnerships sponsored by the managing general partner and its
affiliates have participated in drilling more than 3,100 wells in the
Appalachian Basin since 1985, and none of the wells have been lost because of
title failure. (See "Prior Activities.")

DRILLING AND COMPLETION ACTIVITIES; OPERATION OF PRODUCING WELLS
On receipt of the minimum subscription proceeds for a partnership, the managing
general partner on behalf of the partnership may break escrow, transfer the
escrowed funds to a partnership account, enter into the drilling and operating
agreement, which is attached to the partnership agreement as Exhibit II, with
itself or an affiliate of the managing general partner as operator, and begin
drilling the partnership's wells.

Under the drilling and operating agreement, the responsibility for drilling and
either completing or plugging partnership wells will be on the managing general
partner or an affiliate of the managing general partner as the operator and the
general drilling contractor. Under the drilling and operating agreement, each
partnership is required to prepay the investors' share of the drilling and
completion costs of its wells to the managing general partner as the operator.
If one or more of a partnership's wells will be drilled in the calendar year
after the year in which the advance payment is made, the required advance
payment allows the partnership to secure tax benefits of prepaid intangible
drilling costs based on a substantial business purpose for the advance payment
under the drilling and operating agreement. The managing general partner as
operator and general drilling contractor will begin drilling the wells no later
than March 31, 2007 for the partnerships designated Atlas America Public
#15-2006(___) L.P. (See "Federal Income Tax Consequences - Drilling Contracts.")

During drilling operations the managing general partner's duties as operator and
general drilling contractor will include:

     o    making the necessary arrangements for drilling and completing
          partnership wells and related facilities for which it has
          responsibility under the drilling and operating agreement;

     o    managing and conducting all field operations in connection with
          drilling, testing, and equipping the wells; and

     o    making the technical decisions required in drilling and completing the
          wells.

All partnership wells will be drilled to a sufficient depth to test thoroughly
the objective geological formation unless the managing general partner
determines in its sole discretion that the well shall be completed in a
formation uphole from the objective geological formation.

Under the drilling and operating agreement the managing general partner, as
operator and general drilling contractor, will complete each well if there is a
reasonable probability of obtaining commercial quantities of natural gas or oil.
However, based on its past experience, the managing general partner anticipates
that most of the development wells drilled in the primary and secondary areas
will have to be completed before the managing general partner can determine the
well's productivity. If the managing general partner, as operator and general
drilling contractor, determines that a well should not be completed, then the
well will be plugged and abandoned.

                                       68


During producing operations the managing general partner's duties, as operator,
will include:

     o    managing and conducting all field operations in connection with
          operating and producing the wells;

     o    making the technical decisions required in operating the wells; and

     o    maintaining the wells, equipment, and facilities in good working order
          during their useful life.

The managing general partner, as operator, will be reimbursed for its direct
expenses and will receive well supervision fees at competitive rates for
operating and maintaining the wells during producing operations as discussed in
"Compensation." As discussed in "Summary of Drilling and Operating Agreement,"
the drilling and operating agreement contains a number of other material
provisions which you are urged to review.

Certain wells may be drilled with third-parties owning a portion of the working
interest in the wells. Any other working interest owner in a well will have a
separate agreement with the managing general partner for drilling and operating
the well with differing terms and conditions from those contained in a
partnership's drilling and operating agreement. (See "Federal Income Tax
Consequences - Drilling Contracts.")

SALE OF NATURAL GAS AND OIL PRODUCTION
POLICY OF TREATING ALL WELLS EQUALLY IN A GEOGRAPHIC AREA. The managing general
partner is responsible for selling each partnership's natural gas and oil
production, and its policy is to treat all wells in a given geographic area
equally. This reduces certain potential conflicts of interest among the owners
of the various wells, including the partnerships, concerning to whom and at what
price the natural gas and oil will be sold. For example, the managing general
partner calculates a weighted average selling price for all of the natural gas
sold in the geographic area and this is the price which will be paid to each
partnership in the geographic area for its natural gas. For natural gas sold in
western Pennsylvania for its previous four fiscal years the managing general
partner received an average selling price after deducting all expenses,
including transportation expenses and after the effects of hedging, of
approximately:

     o    $3.34 per mcf, "mcf" means 1,000 cubic feet of natural gas, in 2002;

     o    $4.78 per mcf in 2003;

     o    $5.64 per mcf in 2004; and

     o    $6.72 per mcf in 2005.

If all the natural gas produced cannot be sold because of limited gathering line
or pipeline capacity, or limited demand for the natural gas, which increases
pipeline pressure, then the production that is sold will be from those wells
which have the greatest well pressure and are able to feed into the pipeline,
regardless of which partnerships own the wells. The proceeds from these natural
gas sales will be credited only to the partnerships whose wells produced the
natural gas sold.

GATHERING OF NATURAL GAS. Under the partnership agreement the managing general
partner will be responsible for gathering and transporting the natural gas
produced by the partnerships to interstate pipeline systems, local distribution
companies, and/or end-users in the area. For the majority of each partnership's
natural gas production, including natural gas in the primary areas, as discussed
below, the managing general partner anticipates that it will use the gathering
system owned by Atlas Pipeline Partners, L.P. (and Atlas Pipeline Operating
Partnership) which is a master limited partnership formed by a subsidiary of
Atlas America as managing general partner using Atlas America personnel who act
as its officers and employees. (See "Management - Organizational Diagrams and
Security Ownership of Beneficial Owners.") Atlas Pipeline Partners acquired the
natural gas gathering system and related facilities of Atlas America, Resource
Energy, and Viking Resources in February 2000. The gathering system consists of
more than 1,400 miles of intrastate pipelines located in western Pennsylvania,
eastern Ohio, and western New York.


                                       69


If a partnership's natural gas is not transported through the Atlas Pipeline
Partners gathering system, it is because there is a third-party operator or the
gathering system has not been extended to the wells. In these cases, which
includes the McKean County area and the north central Tennessee area, as
described in "Compensation - Gathering Fees," the natural gas will be
transported through a third-party gathering system, and the partnership will pay
the managing general partner a competitive gathering fee, all or a portion of
which will be paid by it to the third-party. Also, in the north central
Tennessee area, the managing general partner and its affiliates may construct a
gathering system in the future for which it will receive gathering fees as
described in "Compensation - Gathering Fees."

As a part of the sale of the gathering system to Atlas Pipeline Partners in
February 2000, Atlas America and its affiliates, Resource Energy and Viking
Resources (the "Atlas entities"), made certain commitments which were intended
to maximize the use and expansion of the gathering system. These commitments
were made pursuant to a master natural gas gathering agreement and an omnibus
agreement which were entered into at the time of sale in February 2000. Both the
master natural gas gathering agreement and the omnibus agreement set forth
continuing obligations of the Atlas entities that have no specified term, except
that they will terminate with respect to future wells drilled by the Atlas
entities if the general partner of Atlas Pipeline Partners, L.P., Atlas Pipeline
Partners GP, LLC (which is owned by Atlas Pipeline Holdings, L.P., a limited
partnership that is conducting a public offering as described in "Management -
Organizational Diagrams and Security Ownership of Beneficial Owners") is removed
without cause and without its consent. However, under the master natural gas
gathering agreement the Atlas entities, including the partnerships in this case
have committed the natural gas production from the wells they drill before
removal of Atlas Pipeline Partners GP, LLC without cause and without its
consent, for the life of the wells. Thus, the termination of the master natural
gas gathering agreement under the circumstance described above will only
terminate the obligation of the Atlas entities, including the partnerships, to
transport their natural gas through Atlas Pipeline Partners gathering system
with respect to wells drilled on or after the termination of the agreement. Some
of these commitments still affect the partnerships. For example, under the
master natural gas gathering agreement the Atlas entities are required to pay a
gathering fee to Atlas Pipeline Partners equal to the greater of $0.35 per mcf
or 16% of the gross sales price for each mcf transported through Atlas Pipeline
Partners' gathering system. If a partnership pays a lesser amount, which is
anticipated by the managing general partner as described in "Compensation -
Gathering Fees," then the Atlas entities must pay the difference to Atlas
Pipeline Partners. If Atlas Pipeline Partners determines that the continued
operation of any part of the gathering system is not economically justified,
then it may elect to discontinue the operation of that portion of the gathering
system. If Atlas Pipeline Partners makes this determination, then it must give
the parties to the agreement the right to purchase that part of the gathering
system for $10.

Under the omnibus agreement, Atlas America is required to commit to Atlas
Pipeline Partners' gathering system all wells it drills and operates, including
those of the partnerships, that are within 2,500 feet of the Atlas Pipeline
Partners gathering system. In addition, the Atlas entities, including the
partnerships, must construct at their own cost, up to 2,500 feet of flowline as
necessary to connect their wells to Atlas Pipeline Partners' gathering system.
Also, Atlas Pipeline Partners must, at its own cost, extend its gathering system
to connect to any flowlines constructed by the Atlas entities, including the
partnerships, that are within 1,000 feet of its gathering system. With respect
to wells to be drilled by Atlas America and its affiliates, including the
partnerships, that will be more than 3,500 feet from Atlas Pipeline Partners'
gathering system, Atlas Pipeline Partners has various options, in its
discretion, to connect those wells to its gathering system at its own cost.
Also, Atlas America and its affiliates may not divest their ownership of Atlas
Pipeline Partners GP, LLC without also divesting their ownership of the entities
serving as managing general partner in all of their affiliated investment
partnerships, including the partnerships, to the same acquirer, except that
Atlas America is permitted to transfer its ownership interest in Atlas Pipeline
Partners GP, LLC to a wholly- or majority-owned direct or indirect subsidiary as
long as Atlas America continues to control that subsidiary. See "Management -
Organizational Diagram and Securities Ownership of Beneficial Owners" regarding
the public offering in Atlas Pipeline Holdings, L.P., which owns Atlas Pipeline
Partners GP, LLC. Further, Atlas Pipeline Partners GP, LLC has pledged its
equity interests in Atlas Pipeline Partners as security for the revolving credit
facility of Atlas America discussed in "Management's Discussion and Analysis of
Financial Condition, Results of Operations, Liquidity and Capital Resources."

                                       70

NATURAL GAS CONTRACTS. As set forth in "- Primary Areas of Operations," each
partnership has three primary areas where it will drill its wells, and the
managing general partner anticipates that there will be a different natural gas
purchaser in each area. Initially, the majority of each partnership's natural
gas production will be sold to UGI Energy Services, Inc., since the managing
general partner anticipates that more prospects will be drilled in the Fayette
County area, which is one of the primary drilling areas, than in the other
areas, and the majority of the natural gas produced from the Fayette County
area will be sold to UGI Energy Services until March 31, 2007 with a portion
sold to Colonial Energy. The natural gas produced from north central Tennessee,
which is one of the three primary areas, will be sold to Duke Energy. The
managing general partner anticipates that the remainder of the natural gas
produced by the partnership from wells drilled in the other primary area
(Clinton/Medina in Western Pennsylvania) and the secondary areas other than
Armstrong County and McKean County will be sold to Amerada Hess Corporation
("Amerada Hess") as discussed below. Amerada Hess is a large, licensed natural
gas supplier in the Ohio Valley and along the east coast of the United States.

The managing general partner and its affiliates previously entered into a
10-year agreement with First Energy Solutions Corporation, which is the
marketing affiliate of First Energy Corporation, a large regional electric
utility. This agreement was sold by First Energy Solutions Corporation to
Amerada Hess effective April 1, 2005. Subject to the exceptions set forth below,
Amerada Hess has the right to buy all of the natural gas produced and delivered
by the managing general partner and its affiliates, which includes each
partnership and the managing general partner's other partnerships, at certain
delivery points with the facilities of East Ohio Gas Company, National Fuel Gas
Distribution, Columbia of Ohio, and Peoples Natural Gas Company, which are local
distribution companies; and National Fuel Gas Supply, Columbia Gas Transmission
Corporation and Tennessee Gas Pipeline Company, which are interstate pipelines.
This contract, which ends April 1, 2009, is important to the managing general
partner and its affiliates because as of December 31, 2005 the managing general
partner and its affiliates, including its prior affiliated partnerships, were
selling approximately 37% of their natural gas production under the agreement
with Amerada Hess and implementing 63% of their forward sales transactions
through Amerada Hess as discussed below. However, as set forth above, each
partnership will sell a much smaller percentage of its natural gas to Amerada
Hess because of certain exceptions to the agreement, including natural gas sold
through interconnects established after the agreement which includes the
majority of the natural gas produced from wells in the Fayette County area, and
natural gas produced from well(s) subject to an agreement under which a
third-party was to arrange for the gathering and sale of the natural gas such as
natural gas produced from wells in north central Tennessee, one of the primary
drilling areas, or in Armstrong County, Pennsylvania and McKean County,
Pennsylvania, which are both secondary areas.

The pricing and delivery arrangements with all of the natural gas purchasers,
including UGI Energy Services, Amerada Hess Corporation, Colonial Energy, Duke
Energy and the other third-parties are tied to the settlement of the New York
Mercantile Exchange Commission ("NYMEX") monthly futures contracts price, which
is reported daily in the Wall Street Journal and with an additional premium paid
because of the location of the natural gas (the Appalachian Basin) in relation
to the natural gas market which is referred to as the basis. The premium over
quoted prices on the NYMEX received by the managing general partner and its
affiliates has ranged between $0.51 to $1.07 per Mcf during the past three
fiscal years. These figures are based on the overall weighted average that the
managing general partner and its affiliates used in their annual reserve reports
for the past three fiscal years. Generally, the purchase agreements may be
suspended for force majeure, which generally means an Act of God. See "- Policy
of Treating All Wells Equally in a Geographic Area" for the weighted average
natural gas prices since 2001. As of July 15, 2005, the agreements with UGI
Energy Services and Amerada Hess are effective through March 31, 2007. Also, UGI
Corporation has provided a $7 million guaranty of the payment obligations of UGI
Energy Services, Inc. until March 31, 2007, subject to termination by UGI
Corporation on 45 days prior written notice.

Pricing for natural gas and oil has been volatile and uncertain for many years.
To limit the managing general partner's and its partnerships' exposure to
decreases in natural gas prices the managing general partner uses forward sales
transactions through its natural gas producers and hedges through contracts such
as regulated NYMEX futures and options contracts and non-regulated
over-the-counter futures contracts with qualified counterparties. The forward
sales transactions require firm delivery of natural gas and, therefore, are
considered normal sales of natural gas, rather than hedges, for accounting
purposes. The futures contracts employed by the managing general partner are
commitments to purchase or sell natural gas at future dates and generally cover
one-month periods for up to 24 months in the future. To assure that the
financial instruments will be used solely for hedging price risks and not for
speculative purposes, the managing general partner has established a committee
to assure that all financial trading is done in compliance with the managing
general partner's hedging policies and procedures. The managing general partner
does not intend to contract for positions that it cannot offset with actual
production.


                                       71


UGI Energy Services, Amerada Hess Corporation, Colonial Energy and other
third-party marketers also use NYMEX based financial instruments to hedge their
pricing exposure, and they make price hedging opportunities available to the
managing general partner. As of April 2, 2006, the majority of the managing
general partner's natural gas was subject to forward sales transactions through
March 31, 2007. The forward sales transactions are similar to NYMEX based
futures contracts, swaps and options, but also require firm physical delivery of
the natural gas. Because of this, the managing general partner limits these
arrangements to much smaller quantities of natural gas than those projected to
be available at any delivery point. The price paid by UGI Energy Services,
Amerada Hess Corporation, Colonial Energy and any other third-party marketers
for certain volumes of natural gas sold under these hedge agreements may be
significantly different from the underlying monthly spot market value.

The portion of natural gas that is subject to forward sales transactions and the
form of the transaction (e.g. fixed pricing, floor and/or costless collar
pricing) changes from time to time. As of April 2, 2006, the managing general
partner's overall forward sales transactions through the natural gas purchasers
for the future months ending March 31, 2007 were approximately as follows:

     o    72% was sold with a fixed price; and

     o    28% was not sold and was subject to market based pricing.

Approximately 52% of these transactions were implemented through Amerada Hess
Corporation and approximately 48% were implemented through UGI Energy Services.

In addition, on October 27, 2005, the managing general partner and its
affiliates implemented financial hedges through its banking counter-party,
Wachovia Bank, and as of April 2, 2006, the managing general partner and its
affiliates have hedged approximately 63% of their production using
fixed-for-floating financial swaps for the period April 1, 2007 though December
31, 2008, and approximately 21% for the period July 1, 2006 through December 31,
2009.

It is difficult to project what portion of these forward sales transactions
through the natural gas purchasers and hedges will be allocated to each
partnership by the managing general partner because of uncertainty about the
quantity, timing, and delivery locations of natural gas that may be produced by
a partnership. Although hedging and the forward sales transactions provide the
partnerships some protection against falling prices, these activities also could
reduce the potential benefits of price increases.

MARKETING OF NATURAL GAS PRODUCTION FROM WELLS IN OTHER AREAS OF THE UNITED
STATES. The managing general partner expects that natural gas produced from
wells drilled in areas of the Appalachian Basin other than described above, will
be primarily tied to the spot market price and supplied to:

     o    gas marketers;

     o    local distribution companies;

     o    industrial or other end-users; and/or

     o    companies generating electricity.

CRUDE OIL. Crude oil produced from the wells will flow directly into storage
tanks where it will be picked up by the oil company, a common carrier, or
pipeline companies acting for the oil company which is purchasing the crude oil.
Unlike natural gas, crude oil does not present any transportation problem. The
managing general partner anticipates selling any oil produced by the wells to
regional oil refining companies at the prevailing spot market price for
Appalachian crude oil in spot sales. The managing general partner received an
average selling price for oil for its previous four fiscal years of
approximately $18.92 per barrel in 2002; $29.06 per barrel in 2003; $34.41 per
barrel in 2004; and $50.00 per barrel in 2005. During the term of the
partnerships it is anticipated that the price of oil will be uncertain and
volatile.

INSURANCE

Since 1972 the managing general partner and its affiliates, including its
partnerships, have been involved in the drilling of more than 5,300 wells, most
of which were developmental wells, in Ohio, Pennsylvania, and other areas of the
Appalachian Basin. They have made only one material insurance claim. In February
2004, one of the wells in another investment partnership incurred an
uncontrolled flow of natural gas and oil with a fire during drilling. These
problems with the well were subsequently controlled, but they resulted in the
loss of a subcontractor's drilling rig and third-party claims. As of April 19,
2005, the managing general partner's insurance carrier had paid approximately
$1.6 million to third-parties for property damage claims and additional claims
have been submitted which have not yet been paid. The managing general partner's
insurance company is exploring all avenues for subrogation. In addition, in
February 2006, there was a well fire during the drilling of a well in Fayette
County, Pennsylvania which resulted in a claim against the managing general
partner's insurance carrier. See "Actions to be Taken by Managing General
Partner to Reduce Risks of Additional Payments by Investor General Partners -
Insurance" for a discussion of the insurance coverage for a partnership's
benefit.

USE OF CONSULTANTS AND SUBCONTRACTORS

The partnership agreement authorizes the managing general partner to use the
services of independent outside consultants and subcontractors on behalf of the
partnerships. The services will normally be paid on a per diem or other cash fee
basis and will be charged to the partnership on whose behalf the costs were
incurred as either a direct cost or as a direct expense under the drilling and
operating agreement. These charges will be in addition to the nonaccountable,
fixed payment reimbursement paid to the managing general partner for
administrative costs and well supervision fees paid to the managing general
partner as operator as discussed in "Compensation."

                       COMPETITION, MARKETS AND REGULATION

NATURAL GAS REGULATION
Governmental agencies regulate the production and transportation of 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 into intrastate markets, and the Federal Energy Regulatory Commission
("FERC") regulates the interstate transportation of natural gas.

Natural gas prices have not been regulated since 1993, and the price of natural
gas is subject to the supply and demand for natural gas along with factors such
as the natural gas' BTU content and where the wells are located. Since 1985 FERC
has sought to promote greater competition in natural gas markets in the United
States. Traditionally, natural gas was sold by producers to interstate pipeline
companies which served as wholesalers that resold the natural gas to local
distribution companies for resale to end-users. FERC changed this market
structure by requiring interstate pipeline companies to transport natural gas
for third-parties. In 1992 FERC issued Order 636 and a series of related orders
which required 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 natural gas
producers or suppliers. The premise behind FERC Order 636 was that the
interstate pipeline companies had an unfair advantage over other natural gas
producers or suppliers because they could bundle their sales and transportation
services together. FERC Order 636 is designed to ensure that no natural gas
seller has a competitive advantage over another natural gas seller because it
also provides transportation services.

In 2000 FERC issued Order 637 and subsequent orders to enhance competition by
removing price ceilings on short-term capacity release transactions. It also
enacted other regulatory policies that are intended to enhance competition in
the natural gas market and increase the flexibility of interstate natural gas
transportation. FERC has further required pipeline companies to develop
electronic bulletin boards to provide standardized access to information
concerning capacity and prices.

CRUDE OIL REGULATION
Oil prices are not regulated, and the price is subject to the supply and demand
for oil, along with qualitative factors such as the gravity of the crude oil and
sulfur content differentials.

                                       73


COMPETITION AND MARKETS
There are many companies engaged in natural gas and oil drilling operations in
the Appalachian Basin, where all or most of the wells in each partnership will
be located. According to the Energy Information Administration, the independent
statistical and analytical agency within the Department of Energy, in 2004 there
were 23 quadrillion BTU of natural gas consumed in the United States which
represented approximately 23% of the total energy used. The Appalachian Basin
accounted for approximately 5.7% of the total domestic natural gas production in
the United States in 2004 and represented approximately 12.5% of the total
number of wells drilled in the United States during 2004. Also, according to the
Natural Gas Annual 2004 Report, which is published by the Energy Information
Administration Office of Oil and Gas, as of December 31, 2004, the Appalachian
Basin's economically recoverable natural gas reserves represented approximately
8% of total domestic natural gas reserves.

The natural gas and oil industry is highly competitive in all phases, including
acquiring suitable leases to drill and marketing natural gas and oil production
from the wells. Product availability and price are the principal means of
competing in selling natural gas and oil. Many of the partnerships' competitors
will have financial resources and staffs larger than those available to the
partnerships. This may enable them to identify and acquire desirable leases and
market their natural gas and oil production more effectively than the managing
general partner and the partnerships. While it is impossible to accurately
determine the partnerships' industry position, the managing general partner does
not consider that the partnerships' intended operations will be a significant
factor in the industry.

The natural gas and oil industry has from time to time experienced periods of
rapid cost increases. The increase in natural gas and oil prices over the last
several years currently has increased the demand for drilling rigs and other
related equipment, and the costs of drilling and completing natural gas and oil
wells also have increased. Additionally, the managing general partner and its
affiliates have experienced an increase in the cost of tubular steel used in
drilling the wells as a result of rising steel prices. Because each
partnership's wells will be drilled on a cost plus basis as described in
"Compensation - Drilling Contracts," these increased costs will increase the
partnerships' costs to drill and complete their wells. Also, the reduced
availability of drilling rigs and other related equipment may make it more
difficult to drill each partnership's wells in a timely manner or to comply with
the prepaid intangible drilling costs rules discussed in "Federal Income Tax
Consequences - Drilling Contracts." Further, over the term of each partnership
there may be fluctuating or increasing costs in doing business which directly
affect the managing general partner's ability to operate the partnership's wells
at acceptable price levels.

The natural gas and oil produced by your partnership's wells must be marketed
for you to receive revenues. During the fiscal years ending 2005, 2004, and
2003, the managing general partner did not experience any problems in selling
natural gas and oil, although the prices varied significantly during those
periods. As set forth above, natural gas and oil prices are not regulated, but
instead are subject to factors which are generally beyond the partnerships' and
the managing general partner's control such as the supply and demand for the
natural gas and oil. For example, reduced natural gas demand and/or excess
natural gas supplies will result in lower prices. Other factors affecting the
price and/or marketing of natural gas and oil production, which are also beyond
the control of the managing general partner and the partnerships and cannot be
accurately predicted, are the following:

     o    the proximity, availability, and capacity of pipelines and other
          transportation facilities;

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

     o    competition from alternative fuels when large consumers of natural gas
          are able to convert to alternative fuel use systems;

     o    local, state, and federal regulations regarding production and
          transportation;

     o    the general level of market demand for natural gas and oil on a
          regional, national and worldwide basis;

      o   fluctuating seasonal supply and demand for natural gas and oil because
          of various factors such as home heating requirements in the winter
          months, although seasonal anomalies such as mild winters or hot
          summers sometimes lessen this fluctuation, and certain natural gas
          users with natural gas storage facilities purchase a portion of the
          natural gas they anticipate they will need for the winter during the
          summer, which also can lessen seasonal demand fluctuations;


                                       74


     o    political instability and/or war or terrorist acts in natural gas and
          oil producing countries;

     o    the amount of domestic production of natural gas and oil; and

     o    the amount of foreign imports of natural gas and oil, including liquid
          natural gas from Canada and other countries (which the managing
          general partner believes becomes economic when natural gas prices are
          at or above $3.50 per mcf), and the actions of the members of the
          Organization of Petroleum Exporting Countries ("OPEC"), which include
          production quotas for petroleum products from time to time with the
          intent of increasing, maintaining, or decreasing price levels.

For example, the North American Free Trade Agreement ("NAFTA") eliminated trade
and investment barriers in the United States, Canada, and Mexico. From time to
time since then there have been increased imports of Canadian natural gas into
the United States. Without a corresponding increase in demand in the United
States, the imported natural gas would have an adverse effect on both the price
and volume of natural gas sales from the partnerships' wells.

The managing general partner is unable to predict what effect the various
factors set forth above will have on the future price of the natural gas and oil
sold from the partnerships' wells. According to the Annual Energy Outlook 2006
with Projections to 2030 published by the Energy Information Administration
(EIA), total natural gas consumption is projected to increase from 22.34
trillion cubic feet in 2003 to 26.86 trillion cubic feet by 2030. Over that same
period, total natural gas supplies are projected to grow by 4.08 trillion cubic
feet, with domestic natural gas production expected to account for 45% of the
total growth in gas supply, and net imports projected to account for the
remainder. Notwithstanding, wellhead natural gas prices are projected to decline
in the early years of the forecast as a result of the following responses to the
current high prices:

     o    an increase in drilling levels;

     o    the coming online of new production; and

     o    the increase in liquid natural gas ("LNG") imports.

After 2011, however, natural gas prices are projected to increase in response to
the higher exploration and development costs associated with smaller and deeper
natural gas deposits in the remaining domestic natural gas resource base. Also,
the managing general partner believes there have been several developments which
may increase the demand for natural gas, but may or may not be offset by an
increase in the supply of natural gas, which the managing general partner is
unable to predict. For example, 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."
Also, the accelerating deregulation of electricity transmission has caused a
convergence between the natural gas and electric industries. In 2004, according
to information from the Energy Information Administration, the breakout of
energy sources for the generation of electricity in the United States was as
follows:

     o    natural gas fired power plants were used to produce approximately 18%;

     o    coal-fired power plants were used to produce approximately 50%;

     o    nuclear power plants were used to produce approximately 20%; and

     o    large scale hydroelectric projects were used to produce approximately
          7%.

In recent years, the electric industry has increased its use of natural gas
because of increased competition and the enforcement of stringent environmental
regulations. For example, the Environmental Protection Agency has sought to
enforce environmental regulations which increase the cost of operating
coal-fired power plants. According to the Energy Information Administration, the
demand for natural gas by producers of electricity is expected to increase
through the decade. Also, the last nuclear power plant to come online in the
United States was in June 1996, although the existing nuclear power plants have
increased their capacity and the recent energy act includes tax credits for
constructing new nuclear power plants. Unless the price of natural gas increases
to a point where it becomes uneconomic as an energy source as compared to
alternate energy sources, the managing general partner believes that natural gas
is the preferred fuel for many producers of electricity since many electricity
producers have begun moving away from dirtier-burning fuels, such as coal and
oil because of environmental compliance requirements. In this regard, some of
the new natural gas fired power plants which are coming into service are not
designed to allow for switching to other fuels.


                                       75


STATE REGULATIONS
Natural gas and oil operations are regulated in Pennsylvania by the Department
of Environmental Resources. Pennsylvania and the other states where each
partnership's wells may be situated impose a comprehensive statutory and
regulatory scheme for natural gas and oil operations, including supervising the
production activities and the transportation of natural gas sold in intrastate
markets, which creates additional financial and operational burdens. Among other
things, these regulations involve:

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

     o    landowner notification requirements;

     o    certain bonding or other security measures;

     o    minimum well spacing requirements;

     o    restrictions on well locations and underground gas storage;

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

     o    discharge permits for drilling operations;

     o    various reporting requirements; and

     o    well plugging standards and procedures.

These state regulatory agencies also have broad regulatory and enforcement
powers including those associated with pollution and environmental control laws,
which are discussed below.

ENVIRONMENTAL REGULATION
Each partnership's drilling and producing operations are subject to various
federal, state, and local laws covering the discharge of materials into the
environment, or otherwise relating to the protection of the environment. The
Environmental Protection Agency and state and local agencies will require the
partnerships to obtain permits and take other measures with respect to:

     o    the discharge of pollutants into navigable waters;

     o    disposal of wastewater; and

     o    air pollutant emissions.

If these requirements or permits are violated there can be substantial civil and
criminal penalties which will increase if there was willful negligence or
misconduct. In addition, the partnerships may be subject to fines, penalties and
unlimited liability for cleanup costs under various federal laws such as the
Federal Clean Water Act, the Clean Air Act, the Resource Conservation and
Recovery Act, the Oil Pollution Act of 1990, the Toxic Substance Control Act and
the Comprehensive Environmental Response, Compensation and Liability Act of 1980
for oil and/or hazardous substance contamination or other pollution caused by
the drilling activities or the well and its production.

                                       76


Also, a partnership's liability can extend to pollution costs that occurred on
the leases before they were acquired by the partnership. Although the managing
general partner will not transfer any lease to a partnership if it has actual
knowledge that there is an existing potential environmental liability on the
lease, there will not be an independent environmental audit of the leases before
they are transferred to a partnership. Thus, there is a risk that the leases
will have potential environmental liability even before drilling begins.

A partnership's required compliance with these environmental laws and
regulations may cause delays or increase the cost of the partnership's drilling
and producing activities. Because these laws and regulations are frequently
changed, the managing general partner is unable to predict the ultimate costs of
complying with present and future environmental laws and regulations. Also, the
managing general partner is unable to obtain insurance to protect against many
environmental claims.

PROPOSED REGULATION
From time to time there are a number of proposals considered in Congress and in
the legislatures and agencies of various states that if enacted would
significantly and adversely affect the natural gas and oil industry and the
partnerships. The proposals involve, among other things:

      o   limiting the disposal of waste water from wells or the emission of
          greenhouse gases, which could substantially increase a partnership's
          operating costs and make the partnership's wells uneconomical to
          produce;

     o    changes in the federal income tax benefits for drilling natural gas
          and oil wells as discussed in "Federal Income Tax Consequences"; and

     o    tax credits and other incentives for the creation or expansion of
          alternative energy sources to natural gas and oil.

Also, Congress could re-enact price controls or additional taxes on natural gas
in the future. However, it is impossible to accurately predict what proposals,
if any, will be enacted and their subsequent effect on a partnership's
activities.

                       PARTICIPATION IN COSTS AND REVENUES

IN GENERAL
The partnership agreement provides for the sharing of partnership costs and
revenues among the managing general partner and you and the other investors. A
tabular summary of the following discussion appears below. Each partnership will
be a separate business entity from the other partnerships, and you will be a
partner only in the partnership in which you invest. You will have no interest
in the business, assets, or tax benefits of the other partnerships unless you
also invest in the other partnerships. Thus, your investment return will depend
solely on the operations and success or lack of success of the particular
partnership in which you invest.

COSTS
1.   ORGANIZATION AND OFFERING COSTS. Organization and offering costs will be
     charged 100% to the managing general partner. However, the managing general
     partner will not receive any credit towards its required capital
     contribution or its revenue share for any organization and offering costs
     charged to it in excess of 15% of a partnership's subscription proceeds.

     o    Organization and offering costs generally means all costs of
          organizing and selling the offering and includes the dealer-manager
          fee, sales commissions, the up to .5% reimbursement for bona fide due
          diligence expenses, and the .5% accountable reimbursement for
          permissible non-cash compensation.

     The managing general partner will pay a portion of a partnership's
     organization and offering costs to itself, its affiliates and independent
     third-parties and it will contribute the remainder to the partnership in
     the form of services related to organizing this offering. The managing
     general partner will receive a credit for these payments and services
     towards its required capital contribution in each partnership. The managing
     general partner's credit for its contribution of services for organization
     costs will be determined based on generally accepted accounting principles.
     The definition of organization and offering costs is set forth in the
     partnership agreement.


                                       77



2.   LEASE COSTS. Each partnership's leases will be contributed to it by the
     managing general partner. The managing general partner will be credited
     with a capital contribution for each lease valued at:

     o    its cost; or

     o    fair market value if the managing general partner has reason to
          believe that cost is materially more than fair market value.

3.   INTANGIBLE DRILLING COSTS. Ninety percent of the subscription proceeds of
     you and the other investors in a partnership will be used to pay 100% of
     the intangible drilling costs incurred by that partnership in drilling and
     completing its wells.

     o    Intangible drilling costs generally means those costs of drilling and
          completing a well that are currently deductible, as compared with
          lease costs, which must be recovered through the depletion allowance,
          and equipment costs, which must be recovered through depreciation
          deductions.

Although subscription proceeds of a partnership may be used to pay the costs of
drilling different wells depending on when the subscriptions are received, 90%
of the subscription proceeds of you and the other investors will be used to pay
intangible drilling costs regardless of when you subscribe. Also, even if the
IRS successfully challenged the managing general partner's characterization of a
portion of these costs as deductible intangible drilling costs, and instead
recharacterized the costs as some other item that may not be currently
deductible, such as equipment costs and/or lease acquisition costs, this
recharacterization by the IRS would have no effect on the allocation and payment
of the costs by you and the other investors under the partnership agreement.

The allocation of each partnership's costs of drilling and completing its wells
between intangible drilling costs, as defined in the partnership agreement, and
equipment costs, as defined as "tangible costs" in the partnership agreement, is
made by the managing general partner, in its sole discretion, when the wells are
drilled.

4.   EQUIPMENT COSTS. Ten percent of the subscription proceeds of you and the
     other investors in a partnership will be used to pay a portion of the
     equipment costs of that partnership. All equipment costs of that
     partnership's wells that exceed 10% of the subscription proceeds of you and
     the other investors in the partnership will be charged to the managing
     general partner.

     o    Equipment costs generally means the costs of drilling and completing a
          well that are not currently deductible and are not lease costs.

5.   OPERATING COSTS, DIRECT COSTS, ADMINISTRATIVE COSTS AND ALL OTHER COSTS.
     Operating costs, direct costs, administrative costs, and all other
     partnership costs of your partnership not specifically charged will be
     charged between the managing general partner and you and the other
     investors in the partnership in the same ratio as the related production
     revenues are being credited.

     o    These costs generally include all costs of partnership administration
          and producing and maintaining the partnership's wells.

                                       78

     Each well in a partnership will have a different productive life and as a
     well becomes uneconomic to produce, it will be plugged and abandoned. The
     costs of plugging and abandoning a well (other than those incurred in
     connection with the drilling of a nonproductive well) are shared between
     the managing general partner and you and the other investors in the same
     percentage as the related production revenues are being shared. For
     example, if the investors are receiving 68% of the partnership revenues and
     the managing general partner is receiving 32% of the partnership revenues,
     then the cost of plugging and abandoning the wells will be shared in the
     same percentages. Typically, the managing general partner will apply the
     salvage value of the equipment towards this obligation. The salvage value
     of the equipment will be shared between you and the other investors and the
     managing general partner based on the total amount of the actual equipment
     costs paid by each, and the managing general partner will in each
     partnership have paid a majority of the partnership's total equipment
     costs, as compared to the total amount of the partnership's equipment costs
     paid by you and the other investors. See "Compensation - Drilling
     Contracts," for a discussion of the partnerships' equipment costs estimated
     by the managing general partner for an average well in the primary drilling
     areas.

     To cover any shortfall for you and the other investors between your share
     of the salvage value of the equipment received by your partnership for a
     well and your share of the plugging and abandoning costs of the well, the
     managing general partner has the right beginning one year after each
     partnership well begins producing to retain up to $200 of partnership
     revenues per month to cover future plugging and abandonment costs of the
     well. This $200 also includes the managing general partner's share of
     revenues, and that portion will be used exclusively for the managing
     general partner's share of the plugging and abandonment costs of the well.
     To the extent any portion of the reserve ultimately is not required for the
     plugging and abandonment costs of the well, then it will be returned to the
     general operating revenues of the partnership.

6.   THE MANAGING GENERAL PARTNER'S REQUIRED CAPITAL CONTRIBUTION. The managing
     general partner's aggregate capital contributions to each partnership must
     not be less than 25% of all capital contributions to that partnership.
     This includes such items as the managing general partner's:

     o    credit for the cost of the leases contributed to the partnership, or
          the fair market value of the leases if the managing general partner
          has a reason to believe that cost is materially more than fair market
          value;

     o    credit for organization and offering costs, including the costs of
          services contributed as organization costs; and

     o    share of partnership equipment costs paid by it to itself as operator
          under the drilling and operating agreement, which includes a
          nonaccountable administrative overhead reimbursement and profit on
          those costs.

The managing general partner's capital contributions must be paid or made at the
time the costs are required to be paid by the partnership, but in any event not
later than the end of the year immediately following the year in which the
partnership had its final closing.

REVENUES
Each partnership's production revenues from all of its wells will be commingled.
Thus, regardless of when you subscribe to a partnership you will share in the
production revenues from all of the wells in that partnership on the same basis
as the other investors in the partnership in proportion to your number of units.

1.   PROCEEDS FROM THE SALE OF LEASES. If a partnership well is sold, a portion
     of the sales proceeds will be allocated to the partners in the same
     proportion as their share of the adjusted tax basis of the property. In
     addition, proceeds will be allocated to the managing general partner to the
     extent of the pre-contribution appreciation in value of the property, if
     any. Any excess will be credited as provided in 4, below.

2.   INTEREST PROCEEDS. Interest income earned on your subscription proceeds
     before your partnership's final closing will be credited to your account
     and paid not later than the partnership's first cash distributions from
     operations. After your partnership's final closing and until the
     subscription proceeds are invested in your partnership's operations, any
     interest income from temporary investments will be allocated pro rata to
     you and the other investors providing the subscription proceeds. All other
     interest income, including interest earned on the deposit of production
     revenues, will be credited as provided in 4, below.

3.   EQUIPMENT PROCEEDS. Proceeds from the sale or other disposition of
     equipment will be credited to the parties charged with the costs of the
     equipment in the ratio in which the costs were charged.

                                       79


4.   PRODUCTION REVENUES. Subject to the managing general partner's
     subordination obligation as described below, the managing general partner
     and the investors in a partnership will share in all of that partnership's
     other revenues, including production revenues, in the same percentage as
     their respective capital contribution bears to the total partnership
     capital contributions, except that the managing general partner will
     receive an additional 7% of that partnership's revenues. However, the
     managing general partner's total revenue share may not exceed 40% of that
     partnership's revenues regardless of the amount of its capital
     contributions. For example, if the managing general partner contributes the
     minimum of 25% of the total partnership capital contributions and the
     investors contribute 75% of the total partnership capital contributions,
     then the managing general partner will receive 32% of the partnership
     revenues and the investors will receive 68% of the partnership revenues. On
     the other hand, if the managing general partner contributes 35% of the
     total partnership capital contributions and the investors contribute 65% of
     the total partnership capital contributions, then the managing general
     partner will receive 40% of the partnership revenues, not 42%, because its
     revenue share cannot exceed 40% of partnership revenues, and the investors
     will receive 60% of partnership revenues.

SUBORDINATION OF PORTION OF MANAGING GENERAL PARTNER'S NET REVENUE SHARE
Each partnership is structured to provide you and the other investors with cash
distributions equal to a minimum of 10% of capital, based on $10,000 per unit,
regardless of the actual subscription price for your units, in each of the first
five 12-month periods beginning with that partnership's first cash distributions
from operations. To help achieve this investment feature, the managing general
partner will subordinate up to 50% of its share, as managing general partner, of
partnership net production revenues, which will be up to between 16% and 20% of
the total partnership net production revenues, depending on the amount of its
capital contributions, during this subordination period.

     o    Partnership net production revenues means gross revenues after
          deduction of the related operating costs, direct costs, administrative
          costs, and all other costs not specifically allocated.

Each partnership's 60-month subordination period will begin with that
partnership's first cash distribution from operations to you and the other
investors. Subordination distributions will be determined by debiting or
crediting current period partnership revenues to the managing general partner as
may be necessary to provide the distributions to you and the other investors. At
any time during the subordination period the managing general partner is
entitled to an additional share of partnership revenues to recoup previous
subordination distributions to the extent your cash distributions from that
partnership exceed the 10% return of capital described above. The specific
formula is set forth in Section 5.01(b)(4)(a) of the partnership agreement.

The managing general partner anticipates that you will benefit from the
subordination if the price of natural gas and oil received by the partnership
and/or the results of the partnership's drilling activities, such as the volume
of natural gas and oil produced from the partnership's wells, are unable to
provide the required return of capital. However, if the wells produce small
natural gas and oil volumes or natural gas and oil prices decrease, then even
with subordination your cash flow may be very small and you may not receive the
10% return of capital for each of the first five years beginning with the
partnership's first cash distribution from operations.

As of January 15, 2006, the managing general partner was not subordinating any
of its net revenues in 13 limited partnerships that currently have the
subordination feature in effect. Since 1993 the managing general partner has had
a subordination feature in 31 of its partnerships and from time to time it has
subordinated its partnership net revenues in 16 of these partnerships. The
managing general partner is entitled to recoup these subordination distributions
during the subordination period to the extent cash distributions to the
investors in these previous partnerships would exceed the specified return to
the investors.

- ----------
(1)  Ninety percent of the subscription proceeds of you and the other investors
     in a partnership will be used to pay 100% of the intangible drilling costs
     incurred by that partnership in drilling and completing its wells.

(2)  Ten percent of the subscription proceeds of you and the other investors in
     a partnership will be used to pay a portion of the equipment costs incurred
     by that partnership in drilling and completing its wells. All equipment
     costs in excess of 10% of that partnership's subscription proceeds will be
     paid by the managing general partner. Thus, the managing general partner
     will pay the majority of each partnership's equipment costs. Equipment
     proceeds, if any, will be credited in the same percentage in which the
     equipment costs were charged. Thus, the managing general partner will
     receive the majority of any equipment proceeds.

(3)  These costs, which also include plugging and abandonment costs of the wells
     after the wells have been drilled and produced, will be charged to the
     parties in the same ratio as the related production revenues are being
     credited.
(4)  Interest earned on your subscription proceeds before a partnership's final
     closing will be credited to your account and paid not later than the
     partnership's first cash distributions from operations. After the
     partnership's final closing and until proceeds from the offering are
     invested in the partnership's operations any interest income from temporary
     investments will be allocated pro rata to the investors providing the
     subscription proceeds. All other interest income in the partnership,
     including interest earned on the deposit of operating revenues, will be
     credited as production revenues are credited.

(5)  In each partnership the managing general partner and the investors will
     share in all of the partnership's other revenues in the same percentage
     that their respective capital contributions bear to the total partnership
     capital contributions, except that the managing general partner will
     receive an additional 7% of the partnership revenues. However, the managing
     general partner's total revenue share in a partnership may not exceed 40%
     of partnership revenues.

(6)  If a portion of the managing general partner's partnership net production
     revenues is subordinated, then the actual allocation of partnership
     revenues between the managing general partner and the investors will vary
     from the allocation described in (5) above.

(7)  The percentage depletion allowances and any marginal well production
     credits will be in the same percentages as the production revenues.

                                       82

ALLOCATION AND ADJUSTMENT AMONG INVESTORS
The investors' share as a group of each partnership's revenues, gains, income,
costs, marginal well production credits, expenses, losses, and other charges and
liabilities generally will be charged and credited among you and the other
investors in that partnership in accordance with the ratio that your respective
number of units bears to the number of units held by all investors as a group in
that partnership, based on $10,000 per unit regardless of the actual
subscription price set forth on the subscription agreement for an investor's
units. These allocations will take into account any investor general partner's
status as a defaulting investor general partner. Certain investors, however,
will pay a discounted subscription price for their units as described in "Plan
of Distribution." Thus, intangible drilling costs and the investors' share of
the equipment costs of drilling and completing the partnership's wells will be
charged among you and the other investors in a partnership as set forth above,
except that these allocations (i.e., intangible drilling costs and equipment
costs) will be based on the respective subscription price you and the other
investors paid for your units as set forth on your subscription agreements,
rather than $10,000 per unit for all units.

DISTRIBUTIONS
The managing general partner will review each partnership's accounts at least
monthly to determine whether cash distributions are appropriate and the amount
to be distributed, if any, taking into account its subordination obligation
discussed above in "- Subordination of Portion of Managing General Partner's Net
Revenue Share." Your partnership will distribute funds to you and the other
investors that the managing general partner, in its sole discretion, does not
believe are necessary for the partnership to retain. Distributions may be
reduced or deferred to the extent partnership revenues are used for any of the
following:

     o    repayment of borrowings;

     o    cost overruns;

     o    remedial work to improve a well's producing capability;

     o    compensation and fees to the managing general partner as described in
          "Risk Factors - Risks Related to an Investment In a Partnership -
          Compensation and Fees to the Managing General Partner Regardless of
          Success of a Partnership's Activities Will Reduce Cash Distributions";

     o    direct costs and general and administrative expenses of the
          partnership;

     o    reserves, including a reserve for the estimated costs of eventually
          plugging and abandoning the wells; or

     o    indemnification of the managing general partner and its affiliates by
          the partnership for losses or liabilities incurred in connection with
          the partnership's activities.

Also, funds will not be advanced or borrowed for distributions if the
distribution amount would exceed the partnership's accrued and received revenues
for the previous four quarters, less paid and accrued operating costs with
respect to the revenues. Any cash distributions from a partnership to the
managing general partner will be made only in conjunction with distributions to
you and the other investors in that partnership and only out of funds properly
allocated to the managing general partner's account.

LIQUIDATION
Each partnership will continue for 50 years unless it is terminated earlier by a
final terminating event as described below, or an event which causes the
dissolution of a limited partnership under the Delaware Revised Uniform Limited
Partnership Act. However, if a partnership terminates on an event which causes a
dissolution under state law and it is not a final terminating event, then a
successor limited partnership will automatically be formed. Thus, only on a
final terminating event will a partnership be liquidated. A final terminating
event is any of the following:

     o    the election to terminate the partnership by the managing general
          partner or the affirmative vote of investors whose units equal a
          majority of the total units;

     o    the termination of the partnership under Section 708(b)(1)(A) of the
          Internal Revenue Code because no part of its business is being carried
          on; or

                                       83


     o    the partnership ceases to be a going concern.

On the partnership's liquidation you will receive your interest in the
partnership to which you subscribed. Generally, your interest in the partnership
means an undivided interest in the partnership's assets, after payments to the
partnership's creditors, in the ratio that your positive capital account bears
to the positive capital accounts of all of the partners in the partnership
(including the managing general partner) until all of the capital accounts have
been reduced to zero. Thereafter, your interest in the remaining partnership
assets will equal your interest in the related partnership revenues.

Any in-kind property distributions to you from the partnership in which you
invest must be made to a liquidating trust or similar entity, unless you
affirmatively consent to receive an in-kind property distribution after being
told the risks associated with the direct ownership of the property or unless
there are alternative arrangements in place which assure that you will not be
responsible for the operation or disposition of the partnership's properties. If
the managing general partner has not received your written consent to a proposed
in-kind property distribution within 30 days after it is mailed, then it will be
presumed that you have not consented. The managing general partner may then sell
the asset at the best price reasonably obtainable from an independent
third-party, or to itself or its affiliates at fair market value as determined
by an independent expert selected by the managing general partner. Also, if the
partnership is liquidated the managing general partner will be repaid any debts
owed to it by the partnership before there are any payments to you and the other
investors in that partnership.

                              CONFLICTS OF INTEREST

IN GENERAL
Conflicts of interest are inherent in natural gas and oil partnerships involving
non-industry investors because the transactions are entered into without arms'
length negotiation. Your interests and those of the managing general partner and
its affiliates may be inconsistent in some respects or in certain instances, and
the managing general partner's actions may not be the most advantageous to you.
Further, the managing general partner depends on its parent company, Atlas
America, for management and administrative functions and financing for capital
expenditures. Neither the partnership agreement nor any other agreement requires
Atlas America to pursue a future business strategy that favors the partnerships.
Atlas America's directors and officers have a fiduciary duty to make decisions
in the best interests of the stockholders of Atlas America. Because the managing
general partner is allowed to take into account the interests of parties other
than the partnerships, such as Atlas America, in resolving partnership conflicts
of interest, this has the effect of limiting its fiduciary duty to the
partnerships.

The following discussion describes certain possible conflicts of interest that
may arise for the managing general partner and its affiliates in the course of
each partnership. For some of the conflicts of interest, but not all, there are
certain limitations on the managing general partner that are designed to reduce,
but which will not eliminate, the conflicts. Other than these limitations the
managing general partner has no procedures to resolve a conflict of interest and
under the terms of the partnership agreement the managing general partner may
resolve the conflict of interest in its sole discretion and best interest.

The following discussion is materially complete; however, other transactions or
dealings may arise in the future that could result in conflicts of interest for
the managing general partner and its affiliates.

CONFLICTS REGARDING TRANSACTIONS WITH THE MANAGING GENERAL PARTNER AND ITS
AFFILIATES
Although the managing general partner believes that the compensation and
reimbursement that it and its affiliates will receive in connection with each
partnership are reasonable, the compensation has been determined solely by the
managing general partner and did not result from negotiations with any
unaffiliated third-party dealing at arms' length. The managing general partner
and its affiliates will receive compensation and reimbursement from each
partnership for their services in drilling, completing, and operating that
partnership's wells under the drilling and operating agreement and will receive
the other fees described in "Compensation" regardless of the success of that
partnership's wells. The managing general partner and its affiliates providing
the services or equipment can be expected to profit from the transactions, and
it is usually in the managing general partner's best interest to enter into
contracts with itself and its affiliates rather than unaffiliated third-parties
even if the contract terms, skill, and experience, offered by the unaffiliated
third-parties are comparable.

                                       84


The partnership agreement provides that when the managing general partner or any
affiliate provides services or equipment to a partnership their fees must be
competitive with the fees charged by unaffiliated third-parties in the same
geographic area engaged in similar businesses. Also, before the managing general
partner or any affiliate may receive competitive fees for providing services or
equipment to a partnership they must be engaged, independently of the
partnership and as an ordinary and ongoing business, in rendering the services
or selling or leasing the equipment and supplies to a substantial extent to
other persons in the natural gas and oil industry in addition to the
partnerships in which the managing general partner or an affiliate has an
interest. If the managing general partner or the affiliate is not engaged in
such a business, then the compensation must be the lesser of its cost or the
competitive rate that could be obtained in the area.

Any services not otherwise described in this prospectus or the partnership
agreement for which the managing general partner or an affiliate is to be
compensated by a partnership must be:

     o    set forth in a written contract that describes the services to be
          rendered and the compensation to be paid; and

     o    cancelable without penalty on 60 days written notice by investors
          whose units equal a majority of the total units.

The compensation, if any, will be reported to you in your partnership's annual
and semiannual reports, and a copy of the contract will be provided to you on
request.

There is also a conflict of interest concerning the purchase price if the
managing general partner or an affiliate purchases a property from a
partnership, which they may do in certain limited circumstances as described in
"- Conflicts Involving the Acquisition of Leases - (6) Limitations on Sale of
Undeveloped and Developed Leases to the Managing General Partner," below.

CONFLICT REGARDING THE DRILLING AND OPERATING AGREEMENT
The managing general partner anticipates that all of the wells drilled by each
partnership will be drilled and operated under the drilling and operating
agreement. This creates a continuing conflict of interest because the managing
general partner must monitor and enforce, on behalf of each partnership, its own
compliance with the drilling and operating agreement and the partnership
agreement, and that of its affiliate, Atlas Pipeline Partners, with the gas
gathering agreement.

CONFLICTS REGARDING SHARING OF COSTS AND REVENUES
The managing general partner will receive a percentage of partnership revenues
greater than the percentage of partnership costs that it pays. This sharing
arrangement may create a conflict of interest between the managing general
partner and you and the other investors in a partnership concerning the
determination of which wells will be drilled by the partnership based on the
risk and profit potential associated with the wells.

In addition, the allocation of all of the intangible drilling costs to you and
the other investors and the majority of the equipment costs to the managing
general partner creates a conflict of interest between the managing general
partner and you and the other investors concerning whether to complete a well.
For example, the completion of a marginally productive well might prove
beneficial to you and the other investors, but not to the managing general
partner. When a completion decision is made you and the other investors will
have already paid the majority of your costs so you will want to pay your share
of the additional costs to complete the well (i.e., 10% of the completion costs
of the well) if there is a reasonable opportunity to recoup your share of the
completion costs plus any portion of the costs paid by you before the completion
attempt. You will want to plug the well, however, if it appears likely that you
will not recoup all of your share of the additional costs to complete the well.

On the other hand, the managing general partner will have paid only a portion of
its costs before this time, and it will want to pay its additional equipment
costs to complete the well only if it is reasonably certain of recouping its
share of the completion costs and making a profit. However, based on its past
experience the managing general partner anticipates that most of the wells in
the primary areas will have to be completed before it can determine the well's
productivity, which would eliminate this potential conflict of interest. In any
event, the managing general partner will not cause any well to be plugged and
abandoned without a completion attempt unless it makes the decision in
accordance with generally accepted oil and gas field practices in the geographic
area of the well location.

                                       85

CONFLICTS REGARDING TAX MATTERS PARTNER
The managing general partner will serve as each partnership's tax matters
partner and represent the partnership before the IRS. The managing general
partner will have broad authority to act on behalf of you and the other
investors in the partnership in any administrative or judicial proceeding
involving the IRS, and this authority may involve conflicts of interest. For
example, potential conflicts include:

     o    whether or not to expend partnership funds to contest a proposed
          adjustment by the IRS, if any, to:

          o    the amount of a partnership's deduction for intangible drilling
               costs, which is allocated 100% to you and the other investors in
               the partnership; or

          o    the amount of the managing general partner's depreciation
               deductions, or the credit to its capital account for contributing
               the leases to a partnership which would decrease the managing
               general partner's liquidation interest in the partnership; or

     o    the amount of the managing general partner's reimbursement from a
          partnership for expenses incurred by it in its role as the tax matters
          partner as a reasonable, ordinary and necessary business deduction.

CONFLICTS REGARDING OTHER ACTIVITIES OF THE MANAGING GENERAL PARTNER, THE
OPERATOR AND THEIR AFFILIATES
The managing general partner will be required to devote to each partnership the
time and attention that it considers necessary for the proper management of the
partnership's activities. However, the managing general partner has sponsored
and continues to manage other natural gas and oil drilling partnerships, which
may be concurrent, and will engage in unrelated business activities, either for
its own account or on behalf of other partnerships, joint ventures,
corporations, or other entities in which it has an interest. This creates a
continuing conflict of interest in allocating management time, services, and
other activities among the partnerships in this program and its other
activities. The managing general partner will determine the allocation of its
management time, services, and other functions on an as-needed basis consistent
with its fiduciary duties among the partnerships in this program and its other
activities. However, the managing general partner depends on its parent company,
Atlas America, for management and administrative functions and financing for
capital expenditures as described in "Management - Transactions with Management
and Affiliates. Thus, the competition for time and services of the managing
general partner and its affiliates could result in insufficient attention to the
management and operation of the partnerships.

Subject to its fiduciary duties, the managing general partner will not be
restricted from participating in other businesses or activities, even if these
other businesses or activities compete with a partnership's activities and
operate in the same areas as the partnership. However, the managing general
partner and its affiliates may pursue business opportunities that are consistent
with the partnership's investment objectives for their own account only after
they have determined that the opportunity either:

     o    cannot be pursued by the partnership because of insufficient funds; or

     o    it is not appropriate for the partnership under the existing
          circumstances.

CONFLICTS INVOLVING THE ACQUISITION OF LEASES
The managing general partner will select, in its sole discretion, the wells to
be drilled by each partnership. Conflicts of interest may arise concerning which
wells will be drilled by each partnership in this program and which wells will
be drilled by the managing general partner's and its affiliates' other
affiliated partnerships or third-party programs in which they serve as
driller/operator. It may be in the managing general partner's or its affiliates'
advantage to have a partnership in this program bear the costs and risks of
drilling a particular well rather than another affiliate. These potential
conflicts of interest will be increased if the managing general partner
organizes and allocates wells to more than one partnership at a time. To lessen
this conflict of interest the managing general partner generally takes a similar
interest in other partnerships when it serves as managing general partner and/or
driller/operator. Also, as discussed in "Proposed Activities," the managing
general partner has a drilling commitment with Knox Energy for the drilling of
300 wells, which creates a conflict of interest in deciding whether each
partnership will drill wells in the areas that will help the managing general
partner satisfy this drilling commitment.


                                       86



When the managing general partner must provide prospects to two or more
partnerships at the same time it will attempt to treat each partnership fairly
on a basis consistent with:

     o    the funds available to the partnerships; and

     o    the time limitations on the investment of funds for the partnerships.

Generally, the managing general partner follows a policy of developing prospects
in the order of what it believes is the "best available prospect." However, the
managing general partner will continually change its assessment of available
prospects based on the acquisition of new leases and information derived from
wells already drilled. The determination of the "best available prospect" is
based on the managing general partner's assessment of the economic potential of
a prospect and its suitability for a particular partnership, including the
following factors:

     o    estimated reserves;

     o    the targeted geological formations;

     o    natural gas and oil markets;

     o    geological and natural gas and oil market diversification within the
          partnerships;

     o    the prospect's net revenue interest;

     o    estimated drilling costs; and

     o    limitations imposed by the prospectus and/or the partnership
          agreement.

The partnership agreement gives the managing general partner the authority to
cause each partnership in this program to acquire undivided interests in natural
gas and oil properties, and to participate with other parties, including other
drilling programs previously or subsequently conducted by the managing general
partner or its affiliates, in the conduct of its drilling operations on those
properties. If conflicts between the interest of a partnership in this program
and other drilling partnerships do arise, then the managing general partner may
be unable to resolve those conflicts to the maximum advantage of the partnership
in this program because the managing general partner must deal fairly with the
investors in all of its drilling partnerships.

In addition, subject to the restrictions set forth below, the managing general
partner decides which prospects and what interest in the prospects to transfer
to a partnership. This will result in a subsequent partnership sponsored by the
managing general partner benefiting from knowledge gained through a prior
partnership's drilling experience in an area and acquiring a prospect adjacent
to the prior partnership's prospect.

No procedures, other than the guidelines set forth below and in "- Procedures to
Reduce Conflicts of Interest," have been established by the managing general
partner to resolve any conflicts that may arise. The partnership agreement
provides that the managing general partner and its affiliates will abide by the
guidelines set forth below. However, with respect to (2), (3), (4), (5), (7) and
(9) there is an exception in the partnership agreement for another program in
which the interest of the managing general partner is substantially similar to
or less than its interest in the partnerships.

                                       87



(1)  TRANSFERS AT COST. All leases will be acquired by each partnership from the
     managing general partner and credited towards its required capital
     contribution to the partnership at the cost of the lease, unless the
     managing general partner has a reason to believe that cost is materially
     more than the fair market value of the property. If the managing general
     partner believes cost is materially more than fair market value, then the
     managing general partner's credit for the contribution must be at a price
     not in excess of the fair market value.

          o    A determination of fair market value must be supported by an
               appraisal from an independent expert and maintained in the
               partnership's records for at least six years.

(2)  EQUAL PROPORTIONATE INTEREST. When the managing general partner sells or
     transfers an oil and gas interest to a partnership, it must, at the same
     time, sell or transfer to the partnership an equal proportionate interest
     in all of its other property in the same prospect.

          o    The term "prospect" generally means an area which is
               believed to contain commercially productive quantities of natural
               gas or oil.

     However, a prospect will be limited to the drilling or spacing unit on
     which one well will be drilled if the following two conditions are met:

          o    the well is being drilled to a geological feature which contains
               proved reserves as defined below; and

          o    the drilling or spacing unit protects against drainage.

     The managing general partner believes that for a prospect located in the
     primary drilling areas as described in "Proposed Activities - Primary Areas
     of Operations," a prospect will consist of the drilling and spacing unit
     because it will meet the test in the preceding sentence.

          o    Proved reserves, generally, are the estimated quantities of
               natural gas and oil which have been demonstrated to be
               recoverable in future years with reasonable certainty under
               existing economic and operating conditions. Proved reserves
               include proved undeveloped reserves which generally are reserves
               expected to be recovered from existing wells where a relatively
               major expenditure is required for recompletion or from new wells
               on undrilled acreage. Reserves on undrilled acreage will be
               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.

     In the primary areas the managing general partner anticipates that the
     drilling of these wells by each partnership may provide the managing
     general partner with offset sites by allowing it to determine, at the
     partnership's expense, the value of adjacent acreage in which the
     partnership would not have any interest. The managing general partner owns
     acreage throughout the primary areas where each partnership's wells will be
     situated. To lessen this conflict of interest, for five years the managing
     general partner may not drill any well:

          o    in the Clinton/Medina geologic formation within 1,650 feet of an
               existing partnership well in Pennsylvania or within 1,000 feet of
               an existing partnership well in Ohio; or

          o    in the Mississippian/Upper Devonian Sandstone reservoirs in
               Fayette, Greene and Westmoreland Counties, Pennsylvania within
               at least 1,000 feet from a producing well, although a
               partnership may drill a new well or re-enter an existing well
               which is closer than 1,000 feet to a plugged and abandoned well.

     If a partnership abandons its interest in a well, then this restriction
     will continue for one year following the abandonment. There are no similar
     prohibitions for the other primary area.


                                       88


(3)  SUBSEQUENTLY ENLARGING PROSPECT. In areas where the prospect is not limited
     to the drilling or spacing unit and the area constituting a partnership's
     prospect is subsequently enlarged based on geological information, which is
     later acquired, then there is the following special provision:

          o    if the prospect is enlarged to cover any area where the managing
               general partner owns a separate property interest and the
               partnership activities were material in establishing the
               existence of proved undeveloped reserves which are attributable
               to the separate property interest, then the separate property
               interest or a portion thereof must be sold to the partnership in
               accordance with (1), (2) and (4).

(4)  TRANSFER OF LESS THAN THE MANAGING GENERAL PARTNER'S AND ITS AFFILIATES'
     ENTIRE INTEREST. If the managing general partner sells or transfers to a
     partnership less than all of its ownership in any prospect, then it must
     comply with the following conditions:

          o    the retained interest must be a proportionate working interest;

          o    the managing general partner's obligations and the partnership's
               obligations must be substantially the same after the sale of the
               interest by the managing general partner or its affiliates; and

          o    the managing general partner's revenue interest must not exceed
               the amount proportionate to its retained working interest.

     For example, if the managing general partner transfers 50% of its working
     interest in a prospect to a partnership and retains a 50% working interest,
     then the partnership will not pay any of the costs associated with the
     managing general partner's retained working interest as a part of the
     transfer. This limitation does not prevent the managing general partner and
     its affiliates from subsequently dealing with their retained working
     interest as they may choose with unaffiliated parties or affiliated
     partnerships. For example, the managing general partner may sell its
     retained working interest to a third-party for a profit.

(5)  LIMITATIONS ON ACTIVITIES OF THE MANAGING GENERAL PARTNER AND ITS
     AFFILIATES ON LEASES ACQUIRED BY A PARTNERSHIP. For a five year period
     after the final closing of a partnership, if the managing general partner
     proposes to acquire an interest from an unaffiliated person in a prospect
     in which the partnership owns an interest or in a prospect in which the
     partnership's interest has been terminated without compensation within one
     year before the proposed acquisition, then the following conditions apply:

     o    if the managing general partner does not currently own property in the
          prospect separately from the partnership, then the managing general
          partner may not buy an interest in the prospect; and

     o    if the managing general partner currently owns a proportionate
          interest in the prospect separately from the partnership, then the
          interest to be acquired must be divided in the same proportion between
          the managing general partner and the partnership as the other property
          in the prospect. However, if the partnership does not have the cash or
          financing to buy the additional interest, then the managing general
          partner is also prohibited from buying the additional interest.

(6)  LIMITATIONS ON SALE OF UNDEVELOPED AND DEVELOPED LEASES TO THE MANAGING
     GENERAL PARTNER. The managing general partner and its affiliates, other
     than an affiliated partnership as set forth in (7) below, may not purchase
     undeveloped leases or receive a farmout from a partnership other than at
     the higher of cost or fair market value. Farmouts to the managing general
     partner and its affiliates also must be made as set forth in (9) below.

                                       89


     The managing general partner and its affiliates, other than an affiliated
     income program, may not purchase any producing natural gas or oil property
     from a partnership unless:

     o    the sale is in connection with the liquidation of the partnership; or

     o    the managing general partner's well supervision fees under the
          drilling and operating agreement for the well have exceeded the net
          revenues of the well, determined without regard to the managing
          general partner's well supervision fees for the well, for a period of
          at least three consecutive months.

     In both cases, the sale must be at fair market value supported by an
     appraisal of an independent expert selected by the managing general
     partner. The appraisal of the property must be maintained in the
     partnership's records for at least six years.

(7)  TRANSFER OF LEASES BETWEEN AFFILIATED LIMITED PARTNERSHIPS. The transfer of
     an undeveloped lease from a partnership to an affiliated drilling limited
     partnership must be made at fair market value if the undeveloped lease has
     been held for more than two years. Otherwise, the transfer may be made at
     cost if the managing general partner deems it to be in the best interest of
     the partnership.

     An affiliated income program may purchase a producing natural gas and oil
     property from a partnership at any time at:

          o    fair market value as supported by an appraisal from an
               independent expert if the property has been held by the
               partnership for more than six months or there have been
               significant expenditures made in connection with the property; or

          o    cost as adjusted for intervening operations if the managing
               general partner deems it to be in the best interest of the
               partnership.

     However, these prohibitions do not apply to joint ventures or farmouts
     among affiliated partnerships, provided that:

          o    the respective obligations and revenue sharing of all parties to
               the transaction are substantially the same; and

          o    the compensation arrangement or any other interest or right of
               either the managing general partner or its affiliates is the same
               in each affiliated partnership or if different, the aggregate
               compensation of the managing general partner or the affiliate is
               reduced to reflect the lower compensation arrangement.

(8)  LEASES WILL BE ACQUIRED ONLY FOR STATED PURPOSE OF THE PARTNERSHIP. Each
     partnership must acquire only leases that are reasonably expected to meet
     the stated purposes of the partnership. Also, no leases may be acquired for
     the purpose of a subsequent sale, farmout or other disposition unless the
     acquisition is made after a well has been drilled to a depth sufficient to
     indicate that the acquisition would be in the partnership's best interest.

(9)  FARMOUT. The managing general partner will not assign to a partnership the
     working interest in a prospect for the purpose of a subsequent farmout,
     sale or other disposition. The managing general partner will not enter into
     a farmout to avoid paying its share of the costs related to drilling an
     undeveloped lease. However, the managing general partner's decision with
     respect to making a farmout and the terms of a farmout from a partnership
     involve conflicts of interest since the managing general partner may
     benefit from cost savings and reduction of risk.

     The partnership may farmout an undeveloped lease or well activity to the
     managing general partner, its affiliates or an unaffiliated third-party
     only if the managing general partner, exercising the standard of a prudent
     operator, determines that:

                                       90


          o    the partnership lacks the funds to complete the oil and gas
               operations on the lease or well and cannot obtain suitable
               financing;

          o    drilling on the lease or the intended well activity would
               concentrate excessive funds in one location, creating undue risks
               to the partnership;

          o    the leases or well activity have been downgraded by events
               occurring after assignment to the partnership so that development
               of the leases or well activity would not be desirable; or

          o    the best interests of the partnership would be served.

     If the partnership farmouts a lease or well activity, the managing general
     partner must retain on behalf of the partnership the economic interests and
     concessions as a reasonably prudent oil and gas operator would or could
     retain under the circumstances prevailing at the time, consistent with
     industry practices. However, if the farmout is made to the managing general
     partner or its affiliates there is a conflict of interest since the
     managing general partner will represent both the partnership and itself or
     an affiliate. Although the conflict of interest may be resolved to the
     managing general partner's benefit, the managing general partner must still
     retain on behalf of the partnership the economic interests and concessions
     as a reasonably prudent oil and gas operator would or could retain under
     the circumstances prevailing at the time, consistent with industry
     practices.

CONFLICTS BETWEEN INVESTORS AND THE MANAGING GENERAL PARTNER AS AN INVESTOR
The managing general partner, its officers, directors, and affiliates may
subscribe for units in each partnership and the price of their units will be
reduced by 10.5% as described in "Plan of Distribution." Even though they pay a
reduced price for their units, these investors generally will:

     o    share in the partnership's costs, revenues, and distributions on the
          same basis as the other investors as described in "Participation in
          Costs and Revenues"; and

     o    have the same voting rights, except as discussed below.

Any subscription for units by the managing general partner, its officers,
directors, or affiliates in the partnership in which you invest will dilute the
voting rights of you and the other investors and there may be a conflict with
respect to certain matters. The managing general partner and its officers,
directors and affiliates, however, are prohibited from voting with respect to
certain matters as described in "Summary of Partnership Agreement - Voting
Rights."

LACK OF INDEPENDENT UNDERWRITER AND DUE DILIGENCE INVESTIGATION
The terms of this offering, the partnership agreement, and the drilling and
operating agreement were determined by the managing general partner without
arms' length negotiations. You and the other investors have not been separately
represented by legal counsel, who might have negotiated more favorable terms for
you and the other investors in this offering and the agreements.

Also, there was not an extensive in-depth "due diligence" investigation of the
existing and proposed business activities of the partnerships and the managing
general partner that would be provided by independent underwriters. Although
Anthem Securities, which is affiliated with the managing general partner, serves
as dealer-manager and will receive reimbursement of bona fide due diligence
expenses for certain due diligence investigations conducted by the selling
agents which will be reallowed to the selling agents, its due diligence
examination concerning this offering cannot be considered to be independent.

CONFLICTS CONCERNING LEGAL COUNSEL
The managing general partner anticipates that its legal counsel will also serve
as legal counsel to each partnership and that this dual representation will
continue in the future. If a future dispute arises between the managing general
partner and you and the other investors in a partnership, then the managing
general partner will cause you and the other investors to retain separate
counsel. Also, if counsel advises the managing general partner that counsel
reasonably believes its representation of a partnership will be adversely
affected by its responsibilities to the managing general partner, then the
managing general partner will cause you and the other investors in a partnership
to retain separate counsel.

CONFLICTS REGARDING PRESENTMENT FEATURE
You and the other investors in a partnership have the right to present your
units in the partnership to the managing general partner for purchase beginning
with the fifth calendar year after the end of the calendar year in which your
partnership closes. This creates the following conflicts of interest between you
and the managing general partner.

                                       91


          o    The managing general partner may suspend the presentment feature
               if it does not have the necessary cash flow or it cannot borrow
               funds for this purpose on terms which it deems reasonable. Both
               of these determinations are subjective and will be made in the
               managing general partner's sole discretion.

          o    The managing general partner will also determine the purchase
               price based on a reserve report that it prepares and is reviewed
               by an independent expert that it chooses. The formula for
               arriving at the purchase price has many subjective determinations
               that are within the discretion of the managing general partner.

CONFLICTS REGARDING MANAGING GENERAL PARTNER WITHDRAWING OR ASSIGNING AN
INTEREST

A conflict of interest is created with you and the other investors by the
managing general partner's right to do any of the following:

      o   mortgage its managing general partner interest in each partnership;

      o   withdraw an interest in each partnership's wells equal to or less than
          its revenue interest to be used as collateral for a loan to the
          managing general partner; or

      o   assign, subject to the managing general partner's subordination
          obligation, its managing general partner interest in each partnership
          to its affiliates which also may mortgage the interests as collateral
          for their loans, if any.

The amount of partnership net production revenues available to the managing
general partner or an affiliated assignee, if the managing general partner
assigned all, or a portion, of its managing general partner interest in a
partnership to an affiliate, for their respective subordination obligations to
you and the other investors could be reduced or eliminated if there was a
default under a loan to the managing general partner or the affiliated assignee.
Also, under certain circumstances, if the managing general partner or an
affiliated assignee, if all or a portion, of the managing general partner's
managing general partner interest in a partnership was assigned to an affiliate
as discussed above, made a subordination distribution to you and the other
investors after a default to its lenders, then the lenders may be able to recoup
that subordination distribution from you and the other investors.

CONFLICTS REGARDING ORDER OF PIPELINE CONSTRUCTION AND GATHERING FEES
There are conflicts between you and the managing general partner and its
affiliates, because the managing general partner must monitor and enforce on
behalf of the partnerships the compliance of its affiliate, Atlas Pipeline
Partners, with the gas gathering agreement. Also, the managing general partner
may choose well locations for the partnerships that are situated near Atlas
Pipeline Partners' gathering system which would benefit its parent company,
Atlas America, by providing more gathering fees to Atlas Pipeline Partners, even
if there are other well locations available in the same area or other areas
which offer the partnerships a greater potential return. (See "Management -
Organizational Diagrams and Security Ownership of Beneficial Owners.") However,
the managing general partner believes this conflict of interest is substantially
reduced because the managing general partner expects to make the largest single
capital contribution in each partnership as explained in "Capitalization and
Source of Funds and Use of Proceeds." Thus, the managing general partner
believes that it is in the best interest of Atlas America for the managing
general partner to choose prospects for a partnership to drill which have the
greatest potential reserves even if they are not connected to Atlas Pipeline
Partners' gathering system. In addition, Atlas America or an affiliate will
operate the Atlas Pipeline Partners gathering system. Thus, the expansion of the
Atlas Pipeline Partners gathering system will be within the control of the
managing general partner's affiliate, which will attempt to expand the Atlas
Pipeline Partners gathering system to those areas with the greatest number of
wells with the greatest potential reserves. However, Atlas Pipeline Holdings,
L.P., a newly-formed wholly-owned subsidiary of Atlas America, filed a
registered initial public offering of a minority interest in its units on
January 12, 2006. On the successful completion of the offering, Atlas America
will still own an estimated 80% interest in Atlas Pipeline Holdings, L.P., which
owns Atlas Pipeline Partners GP, LLC, the general partner of Atlas Pipeline
Partners. However, Atlas Pipeline Holdings, L.P., as a public company, may be
more susceptible to a change of control. (See "Risk Factors - Risks Related to
the Partnerships' Oil and Gas Operations - Adverse Events in Marketing a
Partnership's Natural Gas Could Reduce Partnership Distributions.")


                                       92


Currently, the managing general partner's affiliates are obligated through their
agreement with Atlas Pipeline Partners to pay the difference between the amount
each partnership pays for gathering fees to the managing general partner as set
forth in "Compensation - Gathering Fees," and the greater of $.35 per mcf or 16%
of the gross sales price for the natural gas. If Atlas Pipeline Partners GP, LLC
were removed as general partner of Atlas Pipeline Partners without cause and
without its consent, this could increase the amount of gathering fees required
to be paid by the partnerships for natural gas transported through Atlas
Pipeline Partners' gathering system since Atlas Pipeline Partners GP, LLC would
no longer receive revenues from Atlas Pipeline Partners, but Atlas America and
its affiliates still would be obligated to pay the difference between the amount
in the master natural gas gathering agreement and the amount paid by the
partnership other than with respect to new wells drilled after the removal.
Thus, the managing general partner and its affiliates may have an incentive to
increase the gathering fees. Any increase in the gathering fees that your
partnership pays would reduce your cash distributions from the partnership.
However, the gathering fees paid to the managing general partner may not exceed
competitive rates.

PROCEDURES TO REDUCE CONFLICTS OF INTEREST
In addition to the procedures set forth in "- Conflicts Involving the
Acquisition of Leases," the managing general partner and its affiliates will
comply with the following procedures in the partnership agreement to reduce some
of the conflicts of interest with you and the other investors. The managing
general partner does not have any other conflict of interest resolution
procedures. Thus, conflicts of interest between the managing general partner and
you and the other investors may not necessarily be resolved in your best
interests. However, the managing general partner believes that its significant
capital contribution to each partnership will reduce the conflicts of interest.

(1)  FAIR AND REASONABLE. The managing general partner may not sell, transfer,
     or convey any property to, or purchase any property from, a partnership
     except pursuant to transactions that are fair and reasonable; nor take any
     action with respect to the assets or property of a partnership which does
     not primarily benefit the partnership.

(2)  NO COMPENSATING BALANCES. The managing general partner may not use a
     partnership's funds as a compensating balance for its own benefit. Thus, a
     partnership's funds may not be used to satisfy any deposit requirements
     imposed by a bank or other financial institution on the managing general
     partner for its own corporate purposes.

(3)  FUTURE PRODUCTION. The managing general partner may not commit the future
     production of a partnership well exclusively for its own benefit.

(4)  DISCLOSURE. Any agreement or arrangement that binds a partnership must be
     fully disclosed in this prospectus.

(5)  NO LOANS FROM A PARTNERSHIP. A partnership may not loan money to the
     managing general partner.

(6)  NO REBATES. The managing general partner may not participate in any
     business arrangements which would circumvent these guidelines including
     receiving rebates or give-ups.

(7)  SALE OF ASSETS. The sale of all or substantially all of the assets of a
     partnership may only be made with the consent of investors whose units
     equal a majority of the total units.

(8)  PARTICIPATION IN OTHER PARTNERSHIPS. If a partnership participates in other
     partnerships or joint ventures, then the terms of the arrangements must not
     circumvent any of the requirements contained in the partnership agreement,
     including the following:

     o    there may be no duplication or increase in organization and offering
          expenses, the managing general partner's compensation, partnership
          expenses, or other fees and costs;

     o    there may be no substantive change in the fiduciary and contractual
          relationship between the managing general partner and you and the
          other investors; and

     o    there may be no diminishment in your voting rights.

                                       93


(9)  INVESTMENTS. A partnership's funds may not be invested in the securities of
     another person except in the following instances:

     o    investments in working interests made in the ordinary course of the
          partnership's business;

     o    temporary investments in income producing short-term highly liquid
          investments, in which there is appropriate safety of principal, such
          as U.S. Treasury Bills;

     o    multi-tier arrangements meeting the requirements of (8) above;

     o    investments involving less than 5% of the total subscription proceeds
          of the partnership that are a necessary and incidental part of a
          property acquisition transaction; and

     o    investments in entities established solely to limit the partnership's
          liabilities associated with the ownership or operation of property or
          equipment, provided that duplicative fees and expenses are prohibited.

(10) SAFEKEEPING OF FUNDS. The managing general partner may not employ, or
     permit another to employ, the funds or assets of a partnership in any
     manner except for the exclusive benefit of the partnership. The managing
     general partner has a fiduciary responsibility for the safekeeping and use
     of all funds and assets of each partnership whether or not in its
     possession or control.

(11) ADVANCE PAYMENTS. Advance payments by each partnership to the managing
     general partner and its affiliates are prohibited except when advance
     payments are required to secure the tax benefits of prepaid intangible
     drilling costs and for a business purpose.

POLICY REGARDING ROLL-UPS
It is possible at some indeterminate time in the future that each partnership
may become involved in a roll-up. In general, a roll-up means a transaction
involving the acquisition, merger, conversion, or consolidation of a partnership
with or into another partnership, corporation or other entity, and the issuance
of securities by the roll-up entity to you and the other investors. A roll-up
will also include any change in the rights, preferences, and privileges of you
and the other investors in the partnership. These changes could include the
following:

     o    increasing the compensation of the managing general partner;

     o    amending your voting rights;

     o    listing the units on a national securities exchange or on NASDAQ;

     o    changing the partnership's fundamental investment objectives; or

     o    materially altering the partnership's duration.

If a roll-up should occur in the future the partnership agreement provides
various policies which include the following:

     o    an independent expert must appraise all partnership assets as
          discussed in ss4.03(d)(16)(a) of the partnership agreement, and you
          must receive a summary of the appraisal in connection with a proposed
          roll-up;

     o    if you vote "no" on the roll-up proposal, then you will be offered a
          choice of:

          o    accepting the securities of the roll-up entity; or

          o    one of the following:

                                       94


               o   remaining a partner in the partnership and preserving your
                   units in the partnership on the same terms and conditions as
                   existed previously; or

               o   receiving cash in an amount equal to your pro-rata share of
                   the appraised value of the partnership's net assets; and

     o    the partnership will not participate in a proposed roll-up:

          o    unless approved by investors whose units equal 66% of the total
               units;

          o    which would result in the diminishment of your voting rights
               under the roll-up entity's chartering agreement;

          o    which includes provisions which would operate to materially
               impede or frustrate the accumulation of shares by you of the
               securities of the roll-up entity;

          o    in which your right of access to the records of the roll-up
               entity would be less than those provided by the partnership
               agreement; or

          o    in which any of the transaction costs would be borne by the
               partnership if the proposed roll-up is not approved by investors
               whose units equal 66% of the total units.

            FIDUCIARY RESPONSIBILITY OF THE MANAGING GENERAL PARTNER

IN GENERAL
The managing general partner will manage your partnership and its assets. In
conducting your partnership's affairs the managing general partner is
accountable to you as a fiduciary, which under Delaware law generally means that
the managing general partner must exercise due care and deal fairly with you and
the other investors. Neither the partnership agreement nor any other agreement
between the managing general partner and each partnership may contractually
limit any fiduciary duty owed to you and the other investors by the managing
general partner under applicable law except as set forth in Sections 4.01, 4.02,
4.03, 4.04, 4.05, and 4.06 of the partnership agreement. In this regard, the
partnership agreement does permit the managing general partner and its
affiliates to:

     o    have business interests or activities that may conflict with the
          partnerships if they determine that the business opportunity either:

          o    cannot be pursued by the partnership because of insufficient
               funds; or

          o    it is not appropriate for the partnership under the existing
               circumstances;

     o    devote only so much of their time as is necessary to manage the
          affairs of each partnership;

     o    conduct business with the partnerships in a capacity other than as
          managing general partner or sponsor as described in ss.ss.4.01, 4.02,
          4.03, 4.04, 4.05 and 4.06 of the partnership agreement;

     o    manage multiple programs simultaneously; and

     o    be indemnified and held harmless as described below in "- Limitations
          on Managing General Partner Liability as Fiduciary."

Other than as set forth above, the partnership agreement does not excuse the
managing general partner from liability or provide it with any defense for
breach of its fiduciary duty. See "Conflicts of Interest - In General" regarding
the managing general partner's dependence on its parent company, Atlas America,
for management and administrative functions and financing for capital
expenditures. The fiduciary duty owed by the managing general partner to the
partnership is analogous to the fiduciary duty owed by directors to a
corporation and its stockholders, which is commonly referred to as the "business
judgment rule." This rule provides that directors are not liable for mistakes
made in the good faith exercise of honest business judgment or for losses
incurred in the good faith performance of their duties when performed with such
care as an ordinarily prudent person would use. As a result of the business
judgment rule, the managing general partner may not be held liable for mistakes
made or losses incurred in the good faith exercise of reasonable business
judgment as described below in "- Limitations on Managing General Partner
Liability as Fiduciary."


                                       95


If the managing general partner breaches its fiduciary responsibilities, then
you are entitled to an accounting and the recovery of any economic loss caused
by the breach. The Delaware Revised Uniform Limited Partnership Act provides
that a limited partner may institute legal action (a "derivative" action) on a
partnership's behalf to recover damages from a third-party when the managing
general partner refuses to institute the action or where an effort to cause the
managing general partner to do so is not likely to succeed. In addition, the
statutory or case law may permit a limited partner to institute legal action on
behalf of himself and all other similarly situated limited partners (a "class
action") to recover damages from the managing general partner for violations of
its fiduciary duties to the limited partners. This is a rapidly expanding and
changing area of the law, and if you have questions concerning the managing
general partner's duties you are urged to consult your own counsel.

LIMITATIONS ON MANAGING GENERAL PARTNER LIABILITY AS FIDUCIARY
Under the terms of the partnership agreement the managing general partner, the
operator, and their affiliates have limited their liability to each partnership
and to you and the other investors for any loss suffered by your partnership or
you and the other investors in the partnership which arises out of any action or
inaction on their part if:

     o    they determined in good faith that the course of conduct was in the
          best interest of the partnership;

     o    they were acting on behalf of, or performing services for, the
          partnership; and

     o    their course of conduct did not constitute negligence or misconduct.

In addition, the partnership agreement provides for indemnification of the
managing general partner, the operator, and their affiliates by each partnership
against any losses, judgments, liabilities, expenses, and amounts paid in
settlement of any claims sustained by them in connection with that partnership
provided that they meet the standards set forth above. However, there is a more
restrictive standard for indemnification for losses arising from or out of an
alleged violation of federal or state securities laws. Also, to the extent that
any indemnification provision in the partnership agreement purports to include
indemnification for liabilities arising under the Securities Act of 1933, as
amended, you should be aware that, in the SEC's opinion, this indemnification is
contrary to public policy and therefore unenforceable.

Payments arising from the indemnification or agreement to hold harmless are
recoverable only out of the partnership's tangible net assets, which include its
revenues and any insurance proceeds from the types of insurance for which the
managing general partner, the operator and their affiliates may be indemnified
under the partnership agreement. Still, use of partnership funds or assets for
indemnification of the managing general partner, the operator, or an affiliate
would reduce amounts available for partnership operations or for distribution to
you and the other investors.

A partnership may not pay the cost of the portion of any insurance that insures
the managing general partner, the operator, or an affiliate against any
liability for which they cannot be indemnified. However, a partnership's funds
can be advanced to them for legal expenses and other costs incurred in any legal
action for which indemnification is being sought if the partnership has adequate
funds available and certain conditions in the partnership agreement are met.

The effect of the foregoing provisions and the business judgment rule may be to
limit your recourse against the managing general partner.

                         FEDERAL INCOME TAX CONSEQUENCES

INTRODUCTION

The managing general partner has obtained a tax opinion letter from Kunzman &
Bollinger, Inc., special counsel for this offering, with respect to the material
federal income tax consequences of an investment in a partnership by a "typical
investor" as that term is defined in "- Managing General Partner's
Representations," below. Accordingly, the managing general partner will rely on
special counsel's tax opinion letter, and no advance ruling on any tax
consequence of an investment in a partnership will be requested from the IRS.
You are urged to read the entire tax opinion letter, which has been filed as
Exhibit 8 to the registration statement of which this prospectus is a part. (See
"Additional Information," for information on how to obtain a copy of special
counsel's tax opinion letter.)

Although special counsel's tax opinions express what it believes a court would
probably conclude if presented with the applicable federal tax issues, special
counsel's tax opinions are only predictions, and are not guarantees, of the
outcome of the particular tax issues being addressed. The IRS could challenge
special counsel's tax opinions, and the challenge could be sustained in the
courts if litigated and cause adverse tax consequences to you and your
partnership's other investors. Special counsel's tax opinions are based in part
on representations and statements made by the managing general partner in the
tax opinion letter and in this prospectus, including forward looking statements
relating to the partnership and its proposed activities. (See "Forward Looking
Statements and Associated Risks.")

DISCLOSURES AND LIMITATION ON YOUR USE OF TAX OPINION LETTER The following
disclosures are made in special counsel's tax opinion letter.

      o   The tax opinion letter was written to support the promotion or
          marketing of units in the partnerships to potential investors, and
          special counsel has helped the managing general partner organize and
          document the offering of units in the partnerships.

     o    The tax opinion letter is not confidential. There are no limitations
          on the disclosure by any potential investor in a partnership to any
          other person of the tax treatment or tax structure of the partnerships
          or the contents of the tax opinion letter.

     o    Investors in a partnership have no contractual protection against the
          possibility that a portion or all of their intended tax benefits from
          an investment in the partnership ultimately are not sustained if
          challenged by the IRS. (See "Risk Factors - Tax Risks - Your Tax
          Benefits from an Investment in a Partnership Are Not Contractually
          Protected.")


     o    Each potential investor in a partnership is urged to seek advice based
          on his particular circumstances from an independent tax advisor with
          respect to the federal tax consequences to him of an investment in a
          partnership.

                                       97


SPECIAL COUNSEL'S ASSUMPTIONS

Set forth below is a synopsis of the principal assumptions made by special
counsel in giving its opinions.

     o    You will not borrow money to buy units in a partnership from any other
          investor in the same partnership.

     o    You will be personally liable to repay any money you borrow to buy
          units in a partnership.

     o    You will not protect yourself through nonrecourse financing,
          guarantees, stop loss agreements or other similar arrangements from
          losing the money you invest in a partnership.

MANAGING GENERAL PARTNER'S REPRESENTATIONS

In giving its opinions, special counsel relied in part on representations from
the managing general partner set forth in the tax opinion letter, including the
principal representations summarized below.

     o    A "typical investor" in each partnership will be a natural person who
          purchases units in this offering and is a U.S. citizen.


     o    The investor general partner units in each partnership will be
          converted to limited partner units after all of the wells in that
          partnership have been drilled and completed. In this regard, the
          managing general partner anticipates that all of the productive wells
          in each partnership will be drilled and completed no more than 12
          months after that partnership's final closing, and the conversion will
          then follow; however, if the partnership is larger as discussed in
          "Investment Objectives" it may take longer..

     o    Each partnership will elect to currently deduct all of the intangible
          drilling costs of all of its wells.

     o    The managing general partner anticipates that all of each
          partnership's subscription proceeds will be expended in 2006, and you
          will include your share of your partnership's deduction for intangible
          drilling costs on your individual federal income tax return for 2006,
          subject to your right to elect to capitalize and amortize over a
          60-month period a portion or all of your share of your partnership's
          deduction for intangible drilling costs.

     o    Each partnership may have its final closing as late in the year as
          December 31, 2006. Thus, depending primarily on when its subscription
          proceeds are received, each partnership may prepay in 2006 most, if
          not all, of its intangible drilling costs for wells the drilling of
          which will not begin until 2007.

     o    Each partnership will have a calendar year taxable year.

     o    The managing general partner anticipates that most, if not all, of
          each partnership's natural gas and oil production will be marginal
          production which will qualify for potentially higher rates of
          percentage depletion and potentially available marginal well
          production credits.

     o    The principal purpose of each partnership is to locate, produce and
          market natural gas and oil on a profitable basis to its investors,
          apart from tax benefits, as discussed in this prospectus.

                                       98



      o   Each partnership's total abandonment losses under ss.165 of the Code,
          which could include, for example, abandonment losses incurred by a
          partnership for wells drilled which are nonproductive (i.e. a "dry
          hole"), and abandonment losses incurred by a partnership for
          productive wells which have been operated until their commercial
          natural gas and oil reserves have been depleted, will be less than $2
          million, in the aggregate, in any taxable year of each partnership and
          less than $4 million, in the aggregate, during each partnership's
          first six taxable years.

Additional details, assumptions of special counsel, representations of the
managing general partner, and other matters affecting special counsel's opinions
are contained in special counsel's tax opinion letter. You are urged to obtain a
copy of the tax opinion letter from the managing general partner or the SEC, as
set forth in "Additional Information," and read the entire tax opinion letter to
assist your understanding of the federal tax benefits and risks of an investment
in a partnership.

SPECIAL COUNSEL'S OPINIONS
Taxpayers bear the burden of proof to support claimed deductions and tax
credits, and special counsel's opinions are not binding on the IRS or the
courts. Special counsel's tax opinions with respect to an investment in a
partnership by a typical investor, who is sometimes referred to in special
counsel's opinions as a "Participant," "Investor General Partner" or "Limited
Partner," are set forth below.

     (1)  PARTNERSHIP CLASSIFICATION. Each Partnership will be classified as a
          partnership for federal income tax purposes, and not as a corporation.

          (See "- Partnership Classification" in "Discussion of Federal Income
          Tax Consequences," below.)

     (2)  LIMITATIONS ON PASSIVE ACTIVITY LOSSES AND CREDITS. The passive
          activity limitations on losses and credits under ss.469 of the Code
          will apply to:

          o    the initial Limited Partners in a Partnership; and

          o    will not apply to the Investor General Partners in a Partnership
               until after their Investor General Partner Units are converted to
               Limited Partner Units.

          For a discussion of the passive activity limitations on losses and
          credits and the types of entities whose investments in a Partnership
          also will be subject to the passive activity limitations on losses and
          credits, see "- Limitations on Passive Activity Losses and Credits" in
          "Discussion of Federal Income Tax Consequences," below.

     (3)  NOT A PUBLICLY TRADED PARTNERSHIP. No Partnership will be treated as a
          publicly traded partnership under the Code.

          (See "- Publicly Traded Partnership Rules" in "Discussion of Federal
          Income Tax Consequences," below.)

     (4)  BUSINESS EXPENSES. Business expenses, including payments for personal
          services actually rendered in the taxable year in which accrued, which
          are reasonable, ordinary and necessary and do not include amounts for
          items such as Lease acquisition costs, Tangible Costs, Organization
          and Offering Costs and other items which are required to be
          capitalized, are currently deductible.

          o    POTENTIAL LIMITATIONS ON DEDUCTIONS. A Participant's ability in
               any taxable year to use his share of these Partnership deductions
               on his individual federal income tax returns may be reduced,
               eliminated or deferred by the following limitations:

               o    the Participant's personal tax situation, such as the amount
                    of his regular taxable income, alternative minimum taxable
                    income, losses, itemized deductions, personal exemptions,
                    etc., which are not related to his investment in a
                    Partnership;

                                       99


               o    the amount of the Participant's adjusted basis in his Units
                    in the Partnership in which he invests at the end of the
                    Partnership's taxable year;

               o    the amount of the Participant's "at risk" amount in the
                    Partnership in which he invests at the end of the
                    Partnership's taxable year; and

               o    the passive activity limitations on losses and credits in
                    the case of Limited Partners (including Investor General
                    Partners after their Units are converted to Limited Partner
                    Units) who are natural persons, or which are entities that
                    also are subject to the passive activity limitations on
                    losses and credits.

          See "- Limitations on Passive Activity Losses and Credits," "-
          Business Expenses," "- Tax Basis of Units," "- `At Risk' Limitation on
          Losses," and "- Alternative Minimum Tax" in "Discussion of Federal
          Income Tax Consequences," below.

     (5)  INTANGIBLE DRILLING COSTS. Although each Partnership will elect to
          deduct currently all of its Intangible Drilling Costs, each
          Participant in a Partnership may still elect to capitalize and deduct
          all or part of his share of his Partnership's Intangible Drilling
          Costs (other than drilling and completion costs of a re-entry well
          that are not related to deepening the well, if any) ratably over a 60-
          month period as discussed in "- Alternative Minimum Tax," in
          "Discussion of Federal Income Tax Consequences," below. Subject to the
          foregoing, Intangible Drilling Costs paid by a Partnership under the
          terms of bona fide drilling contracts for the Partnership's wells will
          be deductible by Participants who elect to currently deduct their
          share of their Partnership's Intangible Drilling Costs in the taxable
          year in which the payments are made and the drilling services are
          rendered.

          (See "- Intangible Drilling Costs" in "Discussion of Federal Income
          Tax Consequences," below.)

          A Participant's ability in any taxable year to use his share of these
          Partnership deductions on his personal federal income tax returns may
          be reduced, eliminated or deferred by the "Potential Limitations on
          Deductions" set forth in opinion (4) above.

     (6)  PREPAID INTANGIBLE DRILLING COSTS. Subject to each Participant's
          election to capitalize and amortize a portion or all of the
          Participant's share of his Partnership's Intangible Drilling Costs as
          set forth in opinion (5) above, any prepayments of Intangible Drilling
          Costs by a Partnership in 2006 for wells the drilling of which will
          begin after December 31, 2006, but on or before March 31, 2007, will
          be deductible by the Participants in 2006.

          (See "- Drilling Contracts" in "Discussion of Federal Income
          Tax Consequences," below.)

          A Participant's ability in any taxable year to use his share of these
          Partnership deductions on his personal federal income tax returns may
          be reduced, eliminated or deferred by the "Potential Limitations on
          Deductions" set forth in opinion (4) above.

     (7)  DEPLETION ALLOWANCE. The greater of the cost depletion allowance or
          the percentage depletion allowance will be avalable to qualified
          Participants as a current deduction against their share of their
          Partnership's gross income from the sale of natural gas and oil
          production in each taxable year, subject to the following
          restrictions:

          o    a Participant's cost depletion allowance cannot exceed his
               adjusted tax basis in the natural gas or oil property to which it
               relates; and


          o    a Participant's percentage depletion allowance:

                                      100



               o    may not exceed 100% of his taxable income from each natural
                    gas and oil property before the deduction for depletion; and

               o    is limited to 65% of his taxable income for the year
                    computed without regard to percentage depletion, net
                    operating loss carry-backs and capital loss carry-backs and,
                    in the case of a Participant that is a trust, any
                    distributions to its beneficiaries.

          See "- Depletion Allowance" in "Discussion of Federal Income
          Tax Consequences," below.

     (8)  MACRS. Each Partnership's reasonable Tangible Costs for equipment
          placed in its productive wells which cannot be deducted immediately
          will be eligible for cost recovery deductions under the Modified
          Accelerated Cost Recovery System ("MACRS") over a seven year "cost
          recovery period" on a well-by-well basis, beginning in the taxable
          year each well is drilled, completed and made capable of production,
          i.e. placed in service.

          (See "- Depreciation and Cost Recovery Deductions" in "Discussion of
          Federal Income Tax Consequences," below.)


          A Participant's ability in any taxable year to use his share of these
          Partnership deductions on his personal federal income tax returns may
          be reduced, eliminated or deferred by the "Potential Limitations on
          Deductions" set forth in opinion (4), above.

     (9)  TAX BASIS OF UNITS. Each Participant's initial adjusted tax basis in
          his Units in the Partnership in which he invests will be the amount of
          money that he paid for his Units.


          (See "- Tax Basis of Units" in "Discussion of Federal Income Tax
          Consequences," below.)


     (10) AT RISK LIMITATION ON LOSSES. Each Participant's initial "at risk"
          amount in the Partnership in which he invests will be the amount of
          money that he paid for his Units.


          (See "- 'At Risk' Limitation on Losses" in "Discussion of Federal
          Income Tax Consequences," below.)

     (11) ALLOCATIONS. The allocations of income, gain, loss, deduction, and
          credit, or items thereof, and distributions set forth in the
          Partnership Agreement for each Partnership, including the allocations
          of basis and amount realized with respect to a Partnership's natural
          gas and oil properties, will govern each Participant's allocable share
          of those items to the extent the allocations do not cause or increase
          a deficit balance in his Capital Account in the Partnership in which
          he invests.

          (See "- Allocations" in "Discussion of Federal Income Tax
          Consequences," below.)

     (12) SUBSCRIPTION. No gain or loss will be recognized by the Participants
          on payment of their subscriptions to the Partnership in which they
          invest.

     (13) PROFIT MOTIVE, IRS ANTI-ABUSE RULE AND POTENTIALLY RELEVANT JUDICIAL
          DOCTRINES. The Partnerships will possess the requisite profit motive
          under ss.183 of the Code. Also, the IRS anti-abuse rule in Treas. Reg.
          ss.1.701-2 and potentially relevant judicial doctrines will not have a
          material adverse effect on the tax consequences of an investment in a
          Partnership by a Participant as described in our opinions.

          (See "- Profit Motive, IRS Anti-Abuse Rule and Judicial Doctrines
          Limitations on Deductions" in "Discussion of Federal Income Tax
          Consequences," below.)

     (14) REPORTABLE TRANSACTIONS. The Partnerships are not, and should not be
          in the future, reportable transactions under ss.6707A(c) of the Code.



                                      101


          (See "- Federal Interest and Tax Penalties" in "Discussion of Federal
          Income Tax Consequences," below.)

     (15) OVERALL CONCLUSION. Special counsel's overall conclusion is that the
          federal tax treatment of a typical Participant's investment in a
          Partnership as set forth in its opinions above is the proper federal
          tax treatment and will be upheld on the merits if challenged by the
          IRS and litigated. Special counsel's evaluation of the federal income
          tax laws and the expected activities of the Partnerships as
          represented to it by the Managing General Partner in the tax opinion
          letter and as described in the Prospectus causes it to believe that
          the deduction by a typical Participant of all, or substantially all,
          of his allocable share of his Partnership's Intangible Drilling Costs
          in 2006 (even if the drilling of most or all of his Partnership's
          wells begins after December 31, 2006, but on or before March 31,
          2007), as set forth in opinions (5) and (6) above, is the principal
          tax benefit offered by each Partnership to potential Participants and
          also is the proper federal tax treatment, subject to each
          Participant's election to capitalize and amortize a portion or all of
          his share of his Partnership's deduction for Intangible Drilling Costs
          as discussed in "- Alternative Minimum Tax" in "Discussion of Federal
          Income Tax Consequences," below.

          A Participant's ability in any taxable year to use his share of these
          Partnership deductions on his personal federal income tax returns may
          be reduced, eliminated or deferred by the "Potential Limitations on
          Deductions" set forth in opinion (4), above.


          The discussion in this prospectus under the caption "FEDERAL INCOME
          TAX CONSEQUENCES," insofar as it contains statements of federal income
          tax law, is correct in all material respects.

                  DISCUSSION OF FEDERAL INCOME TAX CONSEQUENCES

INTRODUCTION

Special counsel's tax opinions are limited to those set forth above. The
following is a discussion of all material federal income tax issues or
consequences, and any significant federal tax issues, related to the purchase,
ownership and disposition of a partnership's units which will apply to typical
investors in each partnership. Except as otherwise noted below, however,
different tax consequences from those discussed below may apply to foreign
persons, corporations, partnerships, trusts and other prospective investors
which are not treated as typical investors for federal income tax purposes.
Also, the proper treatment of the tax attributes of a partnership by a typical
investor on his individual federal income tax returns may vary from that of
another typical investor. This is because the practical utility of the tax
aspects of any investment depends largely on each investor's particular income
tax position in the year in which items of income, gain, loss, deduction, or
credit, if any, are properly taken into account in computing his federal income
tax liability. In addition, the IRS may challenge the deductions, and credits,
if any, claimed by a partnership or you and the other investors in a
partnership, or the taxable year in which the deductions, and credits, if any,
are claimed, and it is possible that the challenge would be upheld if litigated.
Accordingly, you are urged to seek advice based on your particular circumstances
from an independent tax advisor in evaluating the potential tax consequences to
you of an investment in a partnership.


PARTNERSHIP CLASSIFICATION
For federal income tax purposes a partnership is not a taxable entity. Thus, the
partners, rather than the partnership, receive and report any deductions and tax
credits, if any, as well as the income, from a partnership's operations. Each
partnership has been formed as a limited partnership under the Delaware Revised
Uniform Limited Partnership Act which describes each partnership as a
"partnership." Thus, each partnership automatically will be classified as a
partnership for federal tax purposes since the managing general partner has
represented that neither partnership will elect to be taxed as a corporation.

                                      102


The managing general partner anticipates that all of the subscription proceeds
of each partnership will be expended 2006, and the related income, if any, and
deductions, including the deduction for intangible drilling costs, will be
reflected on their investors' federal income tax returns for 2006.

LIMITATIONS ON PASSIVE ACTIVITY LOSSES AND CREDITS
Under the passive activity rules of the Code, all income of a taxpayer who is
subject to the rules is categorized as:

     o    income from passive activities, such as limited partners' interests in
          a business;

     o    active income, such as salary, bonuses, etc.; or

     o    portfolio income, such as gain, interest, dividends and royalties
          unless earned in the ordinary course of a trade or business.

Losses generated by passive activities can offset only passive income and cannot
be applied against active income or portfolio income. Similar rules apply with
respect to tax credits. (See "- Marginal Well Production Credits," below.)
Suspended passive losses and passive credits which an investor cannot use in his
current tax year may be carried forward indefinitely, but not back, and used to
offset future years' passive activity income, or offset passive activity regular
federal income tax liability (in the case of passive activity credits).


Passive activities include any trade or business in which the taxpayer does not
materially participate on a regular, continuous, and substantial basis. Under
the partnership agreement, limited partners will not have material participation
in the partnership in which they invest. Thus, if you are an individual and you
invest in a partnership as a limited partner, your investment in the partnership
will be subject to the passive activity limitations. The passive activity rules
also apply to certain other types of investors which invest in a partnership as
limited partners, including, for example, trusts, partnerships, some types of
limited liability companies which elect to be treated as corporations for
federal tax purposes, and some types of corporations, as described in more
detail in "Risk Factors - Tax Risks - Limited Partners Need Passive Income to
Use Their Deduction for Intangible Drilling Costs."

Investor general partners also do not materially participate in the partnership
in which they invest. However, because each partnership will own only "working
interests," as defined by the Code, in its wells, and investor general partners
will not have limited liability under Delaware law until they are converted to
limited partners, their deductions and any credits from their partnership will
not be treated as passive deductions or credits under the Code before the
conversion, unless they invest in a partnership through an entity which limits
their liability. For example, if an individual invests in a partnership
indirectly as an investor general partner by using an entity which limits his
personal liability under state law to purchase his units, such as a limited
partnership in which he is not a general partner, a limited liability company or
an S corporation, he will be subject to the passive activity limitations on
deductions and credits the same as if he had invested in the partnership as a
limited partner. (See "- Conversion from Investor General Partner to Limited
Partner" and "- Marginal Well Production Credits," below.)


Contractual limitations on the liability of investor general partners under the
partnership agreement, such as insurance, limited indemnification by the
managing general partner, etc., as compared with limitations on liability under
state law as discussed above, will not cause investor general partners to be
subject to the passive activity limitations on losses and credits. Investor
general partners, however, may be subject to an additional limitation on their
deduction of investment interest expense as a result of their non-passive
deduction of intangible drilling costs. (See "- Limitations on Deduction of
Investment Interest," below.)

                                      103


PUBLICLY TRADED PARTNERSHIP RULES
Net losses and most net credits of a partner from a publicly traded partnership
are suspended and carried forward to be netted against income or regular federal
income tax liability, respectively, from that publicly traded partnership only.
In addition, net losses from other passive activities may not be used to offset
net passive income from a publicly traded partnership. A publicly traded
partnership is a partnership in which interests in the partnership are traded on
an established securities market or are readily tradable on either a secondary
market or the substantial equivalent of a secondary market. However, in special
counsel's opinion neither of the partnerships will be treated as a publicly
traded partnership under the Code. This opinion is based primarily on the
substantial restrictions in the partnership agreement on the ability of you and
the other investors to transfer your units in your partnership. (See
"Transferability of Units - Restrictions on Transfer Imposed by the Securities
Laws, the Tax Laws and the Partnership Agreement.") Also, the managing general
partner has represented that the partnerships' units will be not traded on an
established securities market.

CONVERSION FROM INVESTOR GENERAL PARTNER TO LIMITED PARTNER
If you invest in a partnership as an investor general partner, then your share
of the partnership's deduction for intangible drilling costs in 2006 will not be
subject to the passive activity limitations on losses and credits. This is
because the investor general partner units in each partnership will not be
converted to limited partner units until after all of the wells in that
partnership have been drilled and completed. In this regard, the managing
general partner anticipates that all of each partnership's productive wells will
be drilled and completed no later than 12 months after the partnership's final
closing and the conversion will then follow. However, if all or the majority of
the remaining units are sold in Atlas America Public #15-2006(B) L.P., then it
may take longer for both cash distributions to begin and all of the wells to be
drilled, completed and online to sell production in that partnership. This will
also delay conversion of the investor general partner units to limited partner
units. (See "Actions to be Taken by Managing General Partner to Reduce Risks of
Additional Payments by Investor General Partners," and "- Drilling Contracts,"
below.) After the investor general partner units have been converted to limited
partner units, each former investor general partner will have limited liability
as a limited partner under the Delaware Revised Uniform Limited Partnership Act
with respect to his interest in his partnership's activities after the date of
the conversion.

Concurrently, the former investor general partner will become subject to the
passive activity limitations on losses and credits as a limited partner.
However, the former investor general partner previously will have received a
non-passive loss as an investor general partner in 2006 as a result of his
partnership's deduction for intangible drilling costs. Therefore, the Code
requires that his net income from the partnership's wells after his conversion
to a limited partner must continue to be characterized as non-passive income
which cannot be offset with passive losses. For a discussion of the effect of
this rule on an investor general partner's tax credits, if any, from his
partnership, see "- Marginal Well Production Credits," below. The conversion of
the investor general partner units into limited partner units should not have
any other adverse tax consequences on an investor general partner unless his
share, if any, of any partnership liabilities is reduced as a result of the
conversion. This is because a reduction in a partner's share of liabilities is
treated as a constructive distribution of cash to the partner, which reduces the
partner's basis in his partnership units and is taxable to the partner to the
extent it exceeds his basis in his units. (See "- Tax Basis of Units," below.)

TAXABLE YEAR AND METHOD OF ACCOUNTING
Each partnership will adopt a calendar year taxable year and will use the
accrual method of accounting for federal income tax purposes.

BUSINESS EXPENSES
Ordinary, reasonable and necessary business expenses, including reasonable
compensation for personal services actually rendered, are deductible in the year
incurred. In this regard, the managing general partner has represented that the
amounts payable by each partnership to it and its affiliates, including the
amounts payable to it or its affiliates as general drilling contractor, are
reasonable and competitive amounts that ordinarily would be paid for similar
services in similar transactions in the proposed areas of the partnerships'
operations. (See "Compensation" and "- Drilling Contracts," below.) The fees
paid to the managing general partner and its affiliates by the partnerships will
not be currently deductible, however, to the extent it is determined by the IRS
or the courts that they are:


                                      104


     o    in excess of reasonable compensation;


     o    properly characterized as organization or syndication fees or other
          capital costs, such as lease acquisition costs or equipment costs; or


     o    not "ordinary and necessary" business expenses.

In the event of an IRS audit, payments to the managing general partner and its
affiliates by a partnership will be scrutinized by the IRS to a greater extent
than payments to an unrelated party.

Your ability in any taxable year to use your share of these partnership
deductions on your personal federal income tax returns may be reduced,
eliminated or deferred by the "Potential Limitations on Deductions" set forth in
special counsel's opinion (4) in "Special Counsel's Opinions," above.

Although the partnerships will engage in the production of natural gas and oil
from wells drilled in the United States, the partnerships will not qualify for
the "U.S. production activities deduction." This is because the deduction cannot
exceed 50% of the IRS Form W-2 wages paid by a taxpayer for a tax year, and the
partnerships will not pay any Form W-2 wages since they will not have any
employees. Instead, the partnerships will rely on the managing general partner
and its affiliates to manage them and their respective businesses. (See
"Management.")

INTANGIBLE DRILLING COSTS
You may elect to deduct your share of your partnership's intangible drilling
costs, which include items which do not have salvage value, such as labor, fuel,
repairs, supplies and hauling necessary to the drilling of a well and preparing
it for the production of natural gas or oil, in the taxable year in which your
partnership's wells are drilled and completed. For a discussion of the deduction
of intangible drilling costs that are prepaid by your partnership in 2006 for
wells the drilling of which will not begin until 2007, if any, see "- Drilling
Contracts," below.


Your share of your partnership's gain (if a partnership well is sold at a gain),
or your gain (if your units are sold at a gain), will be treated as ordinary
income, rather than capital gain, to the extent of the previous deductions for
intangible drilling costs you have claimed, but not for the deductions for
operating expenses related to a re-entry well, if any. (See "- Sale of the
Properties" and "- Disposition of Units," below.) Also, productive-well
intangible drilling costs may subject you to an alternative minimum tax in
excess of regular tax unless you elect to deduct all or part of these costs
ratably over a 60 month period. (See "- Alternative Minimum Tax," below.)

Under the partnership agreement, 90% of the subscription proceeds received by
each partnership from its investors will be used to pay 100% of the
partnership's intangible drilling costs of drilling and completing its wells.
(See "Application of Proceeds" and "Participation in Costs and Revenues.") The
IRS could challenge the characterization of a portion of these costs as
currently deductible intangible drilling costs and recharacterize the costs as
some other item which may not be currently deductible. However, this would have
no effect on the allocation and payment of the intangible drilling costs by you
and the other investors under the partnership agreement.


If a partnership re-enters an existing well as described in "Proposed Activities
- - Primary Areas of Operations - Mississippian/Upper Devonian Sandstone
Reservoirs, Fayette County, Pennsylvania," the costs of deepening the well and
completing it to deeper reservoirs, if any, other than equipment costs and lease
costs, will be treated under the Code as intangible drilling costs. The
intangible drilling costs of drilling and completing a re-entry well which are
not related to deepening the well, if any, however, will be treated as operating
expenses which should be expensed in the taxable year they are incurred for
federal income tax purposes. Any intangible drilling costs of a re-entry well
which are treated as operating expenses for federal income tax purposes,
however, will not be characterized as operating costs, instead of intangible
drilling costs, for purposes of allocating the payment of the costs between the
managing general partner and the investors under the partnership agreement, and
cannot be amortized as intangible drilling costs over a 60-month period as
described in "- Alternative Minimum Tax," below. (See "Participation in Costs
and Revenues.")


                                      105


Your ability in any taxable year to use your share of these partnership
deductions on your personal federal income tax returns may be reduced,
eliminated or deferred by the "Potential Limitations on Deductions" set forth in
special counsel's opinion (4) in "Special Counsel's Opinions," above.

You are urged to seek advice based on your particular circumstances from an
independent tax advisor concerning the tax benefits to you of your share of the
partnership's deduction for intangible drilling costs in the partnership in
which you invest.

DRILLING CONTRACTS
Each partnership will enter into the drilling and operating agreement with the
managing general partner or its affiliates, acting as a third-party general
drilling contractor, to drill and complete each partnership well at cost plus a
nonaccountable, fixed payment reimbursement of $15,000 from the investors to the
managing general partner for their share of the managing general partner's
general and administrative overhead plus 15%. The managing general partner
anticipates that, on average over all of the wells drilled and completed by each
partnership, assuming a 100% working interest in each well, its profit of 15%
will be approximately $32,803 per well with respect to the intangible drilling
costs and the portion of equipment costs paid by you and the other investors in
your partnership as described in "Compensation - Drilling Contracts." However,
the actual cost of drilling and completing the wells may be more or less than
the estimated amount, due primarily to the uncertain nature of drilling
operations. Therefore, the managing general partner's 15% profit per well also
could be more or less than the dollar amount estimated by the managing general
partner as set forth above. The managing general partner believes the prices
under the drilling and operating agreement are competitive in the proposed areas
of operation. Nevertheless, the amount of the profit realized by the managing
general partner under the drilling and operating agreement could be challenged
by the IRS as being unreasonable and disallowed as a deductible intangible
drilling cost.

Depending primarily on when their respective subscription proceeds are received,
the managing general partner anticipates that each partnership may prepay in
2006 most, if not all, of its intangible drilling costs for wells the drilling
of which will begin in 2007. In Keller v. Commissioner, 79 T.C. 7 (1982), aff'd
725 F.2d 1173 (8th Cir. 1984), the Tax Court applied a two-part test for the
current deductibility of prepaid intangible drilling and development costs. The
test is:


     o    the expenditure must be a payment rather than a refundable deposit;
          and

     o    the deduction must not result in a material distortion of income
          taking into substantial consideration the business purpose aspects of
          the transaction.


Each partnership will attempt to comply with the guidelines set forth in Keller
with respect to any prepaid intangible drilling costs. The drilling and
operating agreement will require each partnership to prepay in 2006 all of the
partnership's share of the estimated intangible drilling costs, and all of the
investors' share of your partnership's share of the estimated equipment costs,
for drilling and completing specified wells for that partnership, the drilling
of which may begin in 2007. These prepayments of intangible drilling costs
should not result in a loss of a current deduction for the intangible drilling
costs in 2006 if:


     o    the guidelines set forth in Keller are complied with;

     o    there is a legitimate business purpose for the required prepayment;


     o    the drilling of the prepaid wells begins on or before March 31, 2007;


     o    the contract is not merely a sham to control the timing of the
          deduction; and

     o    there is an enforceable contract of economic substance.



                                      106



In this regard, the drilling and operating agreement will require each
partnership to prepay the managing general partner's estimate of the intangible
drilling costs and the investor's share of the equipment costs to drill and
complete the wells specified in the drilling and operating agreement in order to
enable the operator to:


     o    begin site preparation for the wells;

     o    obtain suitable subcontractors at the then current prices; and

     o    insure the availability of equipment and materials.

Under the drilling and operating agreement excess prepaid intangible drilling
costs, if any, will not be refundable to a partnership, but instead will be
applied only to intangible drilling cost overruns, if any, on the other
specified wells being drilled or completed by the partnership or to intangible
drilling costs to be incurred by the partnership in drilling and completing
substitute wells. Under Keller, a provision for substitute wells should not
result in the prepayments being characterized as refundable deposits.

The likelihood that prepayments of intangible drilling costs will be challenged
by the IRS on the grounds that there is no business purpose for the prepayments
is increased if prepayments are not required with respect to 100% of the working
interest in the well. In this regard, the managing general partner anticipates
that less than 100% of the working interest will be acquired by each partnership
in one or more of its wells, and prepayments of intangible drilling costs will
not be required of the other owners of working interests in those wells. In the
view of special counsel, however, a legitimate business purpose for the required
prepayments of intangible drilling costs by the partnerships may exist under the
guidelines set forth in Keller, even though prepayments are not required by the
drilling contractor with respect to a portion of the working interest in the
wells.


In addition, a current deduction for prepaid intangible drilling costs is
available only if the drilling of the wells begins before the close of the 90th
day after the close of the taxable year in which the prepayment was made.
Therefore, under the drilling and operating agreement, the managing general
partner, serving as operator and general drilling contractor, must begin
drilling each partnership's prepaid wells, if any, no later than March 31, 2007.
However, the drilling of any partnership well may be delayed due to
circumstances beyond the control of the managing general partner and the
drilling subcontractors. These circumstances include, for example:


     o    the unavailability of drilling rigs;

     o    decisions of third-party operators to delay drilling the wells;

     o    poor weather conditions;

     o    inability to obtain drilling permits or access right to the drilling
          site; or

     o    title problems;


and the managing general partner will have no liability to any partnership or
its investors if these types of events (i.e., "force majeure") delay beginning
the drilling of any prepaid wells past the 90 day limit imposed by the Code
(i.e., March 31, 2007).

If the drilling of a prepaid partnership well does not begin within the 90 day
time constraint imposed by the Code (i.e., March 31, 2007), deductions claimed
by you and the other investors in that partnership for prepaid intangible
drilling costs for the well in 2006, would not be lost, but those deductions
would be disallowed and deferred to 2007 when the well is actually drilled.


                                      107


Your ability in any taxable year to use your share of these partnership
deductions on your personal federal income tax returns may be reduced,
eliminated or deferred by the "Potential Limitations on Deductions" set forth in
special counsel's opinion (4) in "Special Counsel's Opinions," above.

DEPLETION ALLOWANCE
Proceeds from the sale of each partnership's natural gas and oil production will
constitute ordinary income. A portion of that income will not be taxable under
the depletion allowance which permits the deduction from gross income for
federal income tax purposes of either the percentage depletion allowance or the
cost depletion allowance, whichever is greater. Your share of the partnership's
gain (if a partnership well is sold at a gain), or your gain (if you sell your
units at a gain), will be treated as ordinary income rather than capital gain to
the extent of your previous deductions for depletion which reduced your adjusted
basis in the property or your units. (See "- Sale of the Properties" and "-
Disposition of Units," below.)

Cost depletion for any year is determined by dividing the adjusted tax basis for
the property by the total units of natural gas or oil expected to be recoverable
from the property and then multiplying the resultant quotient by the number of
units actually sold during the year. Cost depletion cannot exceed the adjusted
tax basis of the property to which it relates.


Percentage depletion is available to taxpayers other than "integrated oil
companies," which term does not include the partnerships. Your percentage
depletion allowance is based on your share of your partnership's gross
production income from its natural gas and oil properties. The rate of
percentage depletion is 15%. However, percentage depletion for marginal
production increases 1%, up to a maximum increase of 10%, for each whole dollar
that the domestic wellhead price of crude oil for the immediately preceding year
is less than $20 per barrel without adjustment for inflation. The term "marginal
production" includes natural gas and oil produced from a domestic stripper well
property, which is defined as any property which produces a daily average of 15
or less equivalent barrels of oil, which is equivalent to 90 mcf of natural gas,
per producing well on the property in the calendar year. In this regard, the
managing general partner has represented that most, if not all, of the natural
gas and oil production from each partnership's wells will be marginal production
under this definition in the Code. Therefore, most, if not all, of each
partnership's gross income from the sale of its natural gas and oil production
will qualify for these potentially higher rates of percentage depletion. The
rate of percentage depletion for marginal production in 2006 is 15%, and also is
anticipated by the managing general partner to be 15% in 2007. This rate may
fluctuate from year to year depending on the price of oil, but will not be less
than the statutory rate of 15% nor more than 25%.


Also, percentage depletion:


     o    may not exceed 100% of the taxable income from each natural gas and
          oil property before the deduction for depletion, (this limitation was
          suspended in 2005 with respect to marginal properties, which the
          managing general partner has represented will include most, if not
          all, of each partnership's wells, but as of the date of this
          prospectus this limitation had not been suspended for 2006 and it may
          never be suspended for 2006 or subsequent taxable years); and


     o    is limited to 65% of the taxpayer's taxable income for the year
          computed without regard to percentage depletion, net operating loss
          carry-backs and capital loss carry-backs and, in the case of an
          investor that is a trust, any distributions to its beneficiaries. Any
          disallowed percentage depletion deductions under the preceding
          limitations may be carried forward to the next taxable year.

The availability in any taxable year of your percentage depletion allowance must
be computed separately by you and not by your partnership or for investors in
your partnership as a whole. You are urged to seek advice based on your
particular circumstances from an independent tax advisor with respect to the
availability of percentage depletion to you.

DEPRECIATION AND COST RECOVERY DEDUCTIONS
Ten percent of each partnership's subscription proceeds will be used to pay
equipment costs (i.e. "Tangible Costs"), and the managing general partner will
pay all of the partnership's remaining equipment costs of drilling and
completing its wells. The related depreciation deductions, i.e., cost recovery
deductions under the modified accelerated cost recovery system ("MACRS"), will
be allocated under the partnership agreement between the managing general
partner and the investors in each partnership in proportion to the actual amount
of the partnership's equipment costs paid by each.

                                      108



A partnership's reasonable Tangible Costs for equipment placed in its wells
which cannot be deducted immediately will be recovered through depreciation
deductions over a seven year cost recovery period, using the 200% declining
balance method with a switch to straight-line to maximize the deduction,
beginning in the taxable year each well is "placed in service" by the
partnership. In this regard, the managing general partner anticipates that each
partnership will have all of its wells drilled, completed and placed in service
for the production of natural gas or oil approximately eight to 12 months after
that partnership's final closing. However, if all or the majority of the
remaining units are sold in Atlas America Public #15-2006(B) L.P., then it may
take longer for both cash distributions to begin and all of the wells to be
drilled, completed and online to sell production in that partnership. This will
also delay conversion of the investor general partner units to limited partner
units. In the case of a short partnership tax year, the MACRS deduction will be
prorated on a 12-month basis. No distinction is made between new and used
property and salvage value is disregarded. All property assigned to the 7-year
class is treated as placed in service, or disposed of, in the middle of the
year, unless more than 40% of the total cost of all equipment in a partnership's
wells placed in service during the year is placed in service during the last
three months of the year. If that happens, the depreciation for the full year
will be multiplied by a fraction based on the quarter the equipment is placed in
service: 87.5% for the first quarter, 62.5% for the second, 37.5% for the third,
and 12.5% for the fourth. All of these cost recovery deductions claimed by a
partnership and you and the other investors in that partnership are subject to
recapture as ordinary income rather than capital gain on the sale or other
taxable disposition of the property by the partnership or your units by you.
(See "- Sale of the Properties" and "- Disposition of Units," below.)
Depreciation for alternative minimum tax purposes is computed using the 150%
declining balance method switching to straight-line, for most personal property.
This will result in adjustments in computing the alternative minimum taxable
income of you and the other investors in a partnership in taxable years in which
the partnership claims depreciation deductions. (See "- Alternative Minimum
Tax," below.)


Your ability in any taxable year to use your share of these partnership
deductions on your personal federal income tax returns may be reduced,
eliminated or deferred by the "Potential Limitations on Deductions" set forth in
special counsel's opinion (4) in "Special Counsel's Opinions," above.

MARGINAL WELL PRODUCTION CREDITS
There is a marginal well production credit of 50(cent) per mcf of qualified
natural gas production and $3 per barrel of qualified oil production for
purposes of the regular federal income tax beginning with qualifying production
in 2005. A tax credit, unlike a tax deduction, reduces tax liability on a
dollar-for-dollar basis. This credit, however, cannot be used under current law
to reduce alternative minimum taxes. (See "- Alternative Minimum Tax," below.)
Also, the credit will be reduced proportionately if the reference prices for the
previous calendar year are between $1.67 and $2.00 per mcf for natural gas and
$15 and $18 per barrel for oil. In this regard, neither of the partnership's
natural gas and oil production in 2006, if any, will qualify for this credit in
2006, because the reference prices for natural gas and oil in 2005 will be
substantially above the $2.00 per mcf of natural gas and $18.00 per barrel of
oil prices where the credit phases out completely.

Based on the prices for natural gas and oil in recent years compared with the
prices at which the credit phases out completely, it may appear unlikely that
either partnership's natural gas and oil production will ever qualify for this
credit. (See "Proposed Activities - Sale of Natural Gas Production - Policy of
Treating All Wells Equally in a Geographic Area.") However, prices for natural
gas and oil are volatile and could decrease in the future. (See "Risk Factors -
Risks Related To The Partnerships' Oil and Gas Operations - Partnership
Distributions May be Reduced if There is a Decrease in the Price of Natural Gas
and Oil.") Thus, it is possible that the partnerships' production of natural gas
or oil in one or more taxable years after 2005 could qualify for the marginal
well production credit, depending primarily on the applicable reference prices
for natural gas and oil in the future. However, depending primarily on market
prices for natural gas and oil, which are volatile, each partnership's
production of natural gas and oil may not qualify for marginal well production
credits for many years, if ever.


                                      109


To the extent that your share of your partnership's marginal well production
credits, if any, exceeds your regular federal income tax owed on your share of
the partnership's taxable income, the excess credits, if any, can be used by you
to offset any other regular federal income taxes owed by you, on a
dollar-for-dollar basis, subject to the passive activity limitations if you
invest in a partnership as a limited partner. (See "- Limitations on Passive
Activity Losses and Credits," above.) Also, if you invest in a partnership as an
investor general partner, your share of your partnership's marginal well
production credits, if any, will be an active credit which may offset your
regular federal income tax liability on any type of income. However, after you
are converted to a limited partner in the partnership in which you invest, your
share of the partnership's marginal well production credits, if any, will be
active credits only to the extent of your regular federal income tax liability
which is allocable to your share of any net income of the partnership from the
sale of its natural gas and oil production, which will still be treated as
non-passive income even after you have been converted to a limited partner. (See
"- Conversion from Investor General Partner to Limited Partner," above.) Any
credits in excess of that amount which are allocable to you as a converted
investor general partner, as well as all of the marginal well production credits
allocable to those investors who originally invest in the partnership as limited
partners, will be passive credits which under current law can reduce only your
regular income tax liability attributable to net passive income from the
partnership in which you invest or your other passive activities, if any, except
publicly traded partnership passive activities.

LEASE ACQUISITION COSTS AND ABANDONMENT
Lease acquisition costs, together with the related cost depletion deduction, and
any amortization deductions for geological and geophysical expenses incurred by
the managing general partner after August 8, 2005, with respect to a
partnership's prospects and any abandonment loss for lease acquisition costs,
are allocated under the partnership agreement 100% to the managing general
partner, which will contribute the leases to each partnership as a part of its
capital contribution.


TAX BASIS OF UNITS
Your share of your partnership's losses is allowable only to the extent of the
adjusted basis of your units at the end of your partnership's taxable year. The
adjusted basis of your units will be adjusted, but not below zero, for any gain
or loss to you from a sale or other taxable disposition by the partnership of a
natural gas or oil property, and will be increased by your:

     o    cash subscription payment;

     o    share of partnership income; and

     o    share, if any, of partnership debt.

The adjusted basis of your units will be reduced by your:

     o    share of partnership losses;

     o    share of partnership expenditures that are not deductible in computing
          its taxable income and are not properly chargeable to capital account;

     o    depletion deductions, but not below zero;

     o    cash distributions from the partnership; and

     o    any reduction in your share of your partnership's debt, if any.


The reduction in your share of partnership liabilities, if any, is considered a
cash distribution to you. Should cash distributions to you from your partnership
exceed the tax basis of your units, taxable gain would result to you to the
extent of the excess.

"AT RISK" LIMITATION ON LOSSES
You may use your share of your partnership's losses to offset income from other
sources, but only to the extent of the amount you have "at risk" in your
partnership at the end of a taxable year. This "at risk" limitation on your
share of your partnership's losses, however, does not apply to you if you are a
corporation which is neither an S corporation nor a corporation in which at any
time during the last half of the taxable year five or fewer individuals owned
more than 50% (in value) of the stock. Your initial "at risk" amount is equal to
the amount of money you paid for your units. However, any amounts borrowed by
you to buy your units will not be considered "at risk" if the amounts are
borrowed from another investor in your partnership or anyone related to another
investor in your partnership. In this regard, the managing general partner has
represented that it and its affiliates will not make or arrange financing for
you or any other potential investors to use to purchase units in the
partnerships. Also, the amount you have "at risk" in your partnership will not
include the amount of any loss that you are protected against through:


                                      110


     o    nonrecourse loans;

     o    guarantees;

     o    stop loss agreements; or

     o    other similar arrangements.

DISTRIBUTIONS FROM A PARTNERSHIP
A cash distribution from your partnership to you in excess of the adjusted basis
of your units immediately before the distribution is treated as gain to you from
the sale or exchange of your units to the extent of the excess. Different rules
apply, however, to payments by a partnership to a deceased investor's successor
in interest and to payments for an investor's share of his partnership's
unrealized receivables and inventory items as those terms are defined in ss.751
of the Code. No loss can be recognized by you on these types of distributions,
unless the distribution is made to liquidate your units in your partnership and
then only to the extent of the excess, if any, of your adjusted basis in your
units over the sum of the amount of money distributed to you plus your share of
the basis of any unrealized receivables and inventory items of your partnership.
(See "- Disposition of Units," below, for a discussion of unrealized receivables
and inventory items under ss.751 of the Code.) Other distributions of cash,
disproportionate distributions of property, if any, and liquidating
distributions of your partnership may result in taxable gain or loss to you.

SALE OF THE PROPERTIES
The maximum tax rate on a noncorporate taxpayer's adjusted net capital gain on
the sale of most capital assets held more than a year is 15%, or 5% to the
extent the gain would have been taxed at a 10% or 15% rate if it had been
ordinary income, respectively, for most capital assets. In addition, for 2008
only, the 5% tax rate on adjusted net capital gain was reduced to 0%. The former
maximum tax rates of 18% and 8%, respectively, on qualified five-year gain have
been eliminated. These capital gain rates also apply for purposes of the
alternative minimum tax. (See "- Alternative Minimum Tax," below.) However, the
former tax rates on adjusted net capital gain of 20% and 10%, respectively, are
scheduled to be reinstated on January 1, 2009.


"Adjusted net capital gain" means net capital gain determined without taking
qualified dividend income into account:

     o    reduced (but not below zero) by:

          o    any amount of qualified dividend income taken into acc3ount as
               investment income;

          o    net capital gain that is taxed a maximum rate of 28% (such as
               gain on the sale of most collectibles and gain on the sale of
               qualified small business stock); and

          o    net capital gain that is taxed at a maximum rate of 25% (gain
               attributable to real estate depreciation); and

     o    increased by the amount of qualified dividend income.

"Net capital gain" means the excess of net long-term gain (the excess of
long-term gains over long-term losses) over net short-term loss (the excess of
short-term gains over short-term losses). The annual capital loss limitation for
noncorporate taxpayers is the amount of capital gains plus the lesser of $3,000,
which is reduced to $1,500 for married persons filing separate returns, or the
excess of capital losses over capital gains.

                                      111



Gains from sales of the partnerships' natural gas and oil properties held for
more than 12 months will be treated as long-term capital gains, while a net loss
will be an ordinary deduction. However, if a natural gas or oil property owned
by your partnership is sold, gain will be treated as ordinary income to the
extent of the lesser of:


          o    the amounts which were deducted as intangible drilling costs
               rather than added to the basis of the property, plus deductions
               for depletion which reduced the adjusted basis of the property;
               or

          o    the excess of:

               o    the amount realized, in the case of a sale, exchange or
                    involuntary conversion; or

               o    the fair market value of the interest, in all other cases;

               minus the property's adjusted basis.


In addition, all equipment depreciation deductions, and any losses on previous
sales of a partnership's assets which have not yet been used for the purpose of
treating a portion or all of gains on previous sales of the partnership's
properties for the partnership's five most recent taxable years as ordinary
income will be treated as ordinary income to the extent of any gain on the sale
or other taxable disposition of the property. (See "- Depreciation and Cost
Recovery Deductions," above.) Other gains and losses on sales of natural gas and
oil properties held by a partnership for less than 12 months, if any, will
result in ordinary gains or losses.

DISPOSITION OF UNITS
The sale or exchange, including a purchase by the managing general partner, of
all or some of your units, if held by you as a capital asset for more than 12
months, will result in your recognition of long-term capital gain or loss,
except for your share of the partnership's "ss.751 assets" (i.e. inventory items
and unrealized receivables). "Unrealized receivables" includes any right to
payment for goods delivered, or to be delivered, to the extent the proceeds
would be treated as amounts received from the sale or exchange of non-capital
assets, services rendered or to be rendered, to the extent not previously
includable in income under your partnership's accounting methods, and your
previous deduction for depreciation, depletion and intangible drilling costs.
"Inventory items" includes property properly includable in inventory and
property held primarily for sale to customers in the ordinary course of business
and any other property that would produce ordinary income if sold, including
accounts receivable for goods and services. These tax items are sometimes
referred to in this discussion as "ss.751 assets." All of these tax items may be
recaptured as ordinary income rather than capital gain regardless of how long
you have owned your units. (See "- Sale of the Properties," above.)

If your units are held for 12 months or less, your gain or loss will be
short-term gain or loss. Also, your pro rata share of your partnership's
liabilities, if any, as of the date of the sale or exchange, must be included in
the amount realized by you. Therefore, the gain recognized by you may result in
a tax liability to you greater than the cash proceeds, if any, received by you
from the disposition of your units. In addition to gain from a passive activity,
a portion of any gain recognized by a limited partner on the sale or other
taxable disposition of his units will be characterized as portfolio income under
the passive activity loss rules to the extent the gain is attributable to
portfolio income, e.g. interest income on investments of working capital. (See
"- Limitations on Passive Activity Losses and Credits," above.)


A gift of your units may result in federal and/or state income tax and gift tax
liability to you. Also, interests in different partnerships do not qualify for
tax-free like-kind exchanges. Other types of dispositions of your units may or
may not result in recognition of taxable gain. However, no gain should be
recognized by an investor general partner on the conversion of his investor
general partner units to limited partner units so long as there is no change in
his share of his partnership's liabilities or ss.751 assets as a result of the
conversion. In addition, if you sell or exchange all or some of your units you
are required by the Code to notify your partnership within 30 days or by January
15 of the following year, if earlier. The partnership will then report to the
IRS any information required by the IRS to be reported regarding the transfer of
the units, including your share of your partnership's ss.751 assets which are
subject to recapture as ordinary income as discussed above.

                                      112


If you die, or sell or exchange all of your units, the taxable year of your
partnership will close with respect to you, but not the remaining investors, on
the date of death, sale or exchange, and there will be a proration of
partnership items for the partnership's taxable year. If you sell less than all
of your units, the partnership's taxable year will not terminate with respect to
you, but your proportionate share of the partnership's items of income, gain,
loss, deduction and credit will be determined by taking into account your
varying interests in the partnership during the taxable year.

You are urged to seek advice based on your particular circumstances from an
independent tax advisor before any sale or other disposition of your units,
including any purchase of your units by the managing general partner.

ALTERNATIVE MINIMUM TAX
With limited exceptions, you must pay an alternative minimum tax if it exceeds
your regular federal income tax for the year. Alternative minimum taxable income
is taxable income, plus or minus various adjustments, plus tax preference items.
The principal adjustments and preference items which may apply to typical
investors in a partnership are summarized below.

The tax rate for noncorporate taxpayers is 26% for the first $175,000, $87,500
for married individuals filing separately, of a taxpayer's alternative minimum
taxable income in excess of the exemption amount; and additional alternative
minimum taxable income is taxed at 28%. However, the regular tax rates on
capital gains also will apply for purposes of the alternative minimum tax. (See
"- Sale of the Properties," above.) Subject to the phase-out provisions
summarized below, and as of the date of this prospectus, the exemption amounts
for 2006 have been reduced from the exemption amounts for 2005 as follows:
$45,000 for married individuals filing jointly and surviving spouses ($58,000 in
2005), $33,750 for single persons other than surviving spouses ($40,250 in
2005), and $22,500 for married individuals filing separately ($29,000 in 2005).
The exemption amount for estates and trusts is $22,500 in 2005 and subsequent
years.

The exemption amounts in 2006 set forth above are reduced by 25% of alternative
minimum taxable income in excess of:

     o    $150,000, in the case of married individuals filing a joint return and
          surviving spouses, and the $45,000 amount phases out completely at
          $330,000 (the $58,000 exemption amount in 2005 completely phased out
          when alternative minimum taxable income was $382,000 or more);

     o    $112,500, in the case of unmarried individuals other than surviving
          spouses, the $33,750 amount phases out completely at $247,500 (the
          $40,250 exemption amount in 2005 completely phased out when
          alternative minimum taxable income was $273,500 or more); and

     o    $75,000, in the case of married individuals filing a separate return
          the $22,500 amount phases out completely at $165,000 (the $29,000
          exemption amount in 2005 completely phased out when alternative
          minimum taxable income was $191,000 or more). In addition, in 2006 the
          alternative minimum taxable income of married individuals filing
          separately is increased by the lesser of $22,500 ($29,000 in 2005) or
          25% of the excess of the person's alternative minimum taxable income
          (determined without regard to this provision) over $165,000 ($191,000
          in 2005).

As of the date of this prospectus, the higher exemption amounts for 2005 had not
been extended to 2006. Thus, you are urged to seek advice from an independent
tax advisor to determine whether the exemption amounts for 2006 alternative
minimum tax purposes have been increased after the date of this prospectus.


Some of the principal adjustments to taxable income that are used to determine
alternative minimum taxable income include those summarized below:

                                      113



     o    Depreciation deductions of the costs of the equipment placed in
          service in the wells may not exceed deductions computed using the 150%
          declining balance method. These adjustments are discussed in greater
          detail below. (See "- Depreciation and Cost Recovery Deductions,"
          above.)

     o    Miscellaneous itemized deductions are not allowed.

     o    Medical expenses are deductible only to the extent they exceed 10% of
          adjusted gross income.

     o    State and local property taxes and income taxes, which are itemized
          and deducted for regular tax purposes, are not deductible. (In 2005
          you could elect, instead, to itemize state and local sales taxes for
          regular federal income tax purposes, but as of the date of this
          prospectus this election had not been extended to 2006, thus, you are
          urged to seek advice from an independent tax advisor to determine
          whether this election was subsequently extended to 2006).

     o    Interest deductions are restricted.

     o    The standard deduction and personal exemptions are not allowed.

     o    Only some types of operating losses are deductible.

     o    Passive activity losses are computed differently.

     o    Earlier recognition of income from incentive stock options may be
          required.

The principal tax preference items that must be added to taxable income for
alternative minimum tax purposes include:

     o    excess intangible drilling costs, as discussed below; and

     o    tax-exempt interest earned on specified private activity bonds, less
          any deductions that would have been allowable if the interest were
          included in gross income for regular income tax purposes.

For taxpayers other than "integrated oil companies" as that term is defined in
"- Intangible Drilling Costs," above, which does not include the partnerships,
the 1992 National Energy Bill repealed:

     o    the preference for excess intangible drilling costs; and

     o    the excess percentage depletion preference for natural gas and oil.

The repeal of the excess intangible drilling costs preference, however, under
current law may not result in more than a 40% reduction in the amount of the
taxpayer's alternative minimum taxable income computed as if the excess
intangible drilling costs preference had not been repealed. Under the prior
rules, the amount of intangible drilling costs which is not deductible for
alternative minimum tax purposes is the excess of the "excess intangible
drilling costs" over 65% of net income from natural gas and oil properties. Net
natural gas and oil income is determined for this purpose without subtracting
excess intangible drilling costs. Excess intangible drilling costs is the
regular intangible drilling costs deduction minus the amount that would have
been deducted under 120-month straight-line amortization, or, at the taxpayer's
election, under the cost depletion method. There is no preference item for costs
of nonproductive wells.

Also, you may elect under ss.59(e) of the Code to capitalize all or part of your
share of your partnership's intangible drilling costs and deduct the costs
ratably over a 60-month period beginning with the month in which the costs were
paid or incurred by the partnership. This election also applies for regular tax
purposes and can be revoked only with the IRS' consent. Making this election,
therefore, will include the following principal consequences to you:

                                      114



     o    your regular federal income tax deduction for intangible drilling
          costs in 2006 will be reduced because you must spread the deduction
          for the amount of intangible drilling costs which you elect to
          capitalize over the 60-month amortization period; and


     o    the capitalized intangible drilling costs will not be treated as a
          preference that is included in your alternative minimum taxable
          income.


Other than intangible drilling costs as discussed above, and passive activity
losses and credits in the case of limited partners, the principal tax item that
may have an impact on your alternative minimum taxable income as a result of
investing in a partnership is depreciation of the partnership's equipment
expenses. (See "- Limitations on Passive Activity Losses and Credits," above.)
As noted in "- Depreciation and Cost Recovery Deductions," above, each
partnership's cost recovery deductions for regular income tax purposes will be
computed differently than for alternative minimum tax purposes. Consequently, in
the early years of the cost recovery period of your partnership's equipment, but
not in the later years, your depreciation deductions from the partnership will
be smaller for alternative minimum tax purposes than your depreciation
deductions for regular income tax purposes on the same equipment. This could
cause you to incur, or may increase, your alternative minimum tax liability in
those taxable years. Conversely, this adjustment may decrease your alternative
minimum taxable income in the later years of the cost recovery period. Also,
under current law, your share of your partnership's marginal well production
credits, if any, may not be used to reduce your alternative minimum tax
liability, if any. Also, the rules relating to the alternative minimum tax for
corporations are different from those for individuals which have been summarized
above.


All prospective investors contemplating purchasing units in a partnership are
urged to seek advice based on their particular circumstances from an independent
tax advisor as to the likelihood of them incurring or increasing any alternative
minimum tax liability as a result of an investment in a partnership.

LIMITATIONS ON DEDUCTION OF INVESTMENT INTEREST

Investment interest expense is deductible by a noncorporate taxpayer only to the
extent of net investment income each year, with an indefinite carry forward of
disallowed amounts. An investor general partner's share of any interest expense
incurred by the partnership in which he invests before his investor general
partner units are converted to limited partner units will be subject to the
investment interest limitation. In addition, an investor general partner's share
of the partnership's loss in 2006 as a result of the deduction for intangible
drilling costs will reduce his net investment income and may reduce or eliminate
the deductibility of his investment interest expenses, if any, in that taxable
year, with the disallowed portion to be carried forward to the next taxable
year. These rules, however, do not apply to a partnership's income or expenses
taken into account in computing income or loss from a passive activity in the
case of limited partners. (See "- Limitations on Passive Activity Losses and
Credits," above.)


ALLOCATIONS
The partnership agreement allocates to you your share of your partnership's
income, gains, losses, deductions, and credits, if any, including the deductions
for intangible drilling costs and depreciation. Your capital account in the
partnership in which you invest will be adjusted to reflect your share of these
allocations, and your capital account, as adjusted, will be given effect in
distributions made to you on liquidation of the partnership or your units. Your
capital account in the partnership in which you invest will be:

     o    increased by the amount of money you contribute to the partnership and
          allocations of partnership income and gain to you; and

     o    decreased by the value of property or cash distributed to you by the
          partnership and allocations of partnership losses and deductions to
          you.

                                      115


Also, any marginal well production credits of a partnership will be allocated
among the managing general partner and you and the other investors in the
partnership in which you invest in accordance with each partner's respective
interest in the partnership's production revenues from the sale of its natural
gas and oil production. (See "Participation in Costs and Revenues" and "-
Marginal Well Production Credits," above.)

It also should be noted that your share of items of income, gain, loss,
deduction, and credit, if any, in the partnership in which you invest must be
taken into account by you whether or not you receive any cash distributions from
the partnership. For example, your share of partnership revenues applied by your
partnership to the repayment of loans, if any, or the reserve for plugging
wells, will be included in your gross income in a manner analogous to an actual
distribution of the revenues (and income) to you. Thus, you may have tax
liability on taxable income from your partnership for a particular year in
excess of any cash distributions from the partnership to you with respect to
that year. To the extent a partnership has cash available for distribution,
however, it is the managing general partner's policy that partnership cash
distributions to you and the other investors in that partnership will not be
less than the managing general partner's estimate of the investors' income tax
liability with respect to that partnership's income.

If any allocation under the partnership agreement is not recognized for federal
income tax purposes, your share of the items subject to the allocation will be
determined in accordance with your interest in the partnership in which you
invest by considering all of the relevant facts and circumstances. To the extent
deductions or credits allocated by the partnership agreement exceed deductions
or credits which would be allowed under a reallocation of those tax items by the
IRS, you may incur a greater tax burden.

PARTNERSHIP BORROWINGS
Under the partnership agreement, only the managing general partner and its
affiliates may make loans to the partnerships. The use of partnership revenues
taxable to you to repay borrowings by your partnership could create income tax
liability for you in excess of your cash distributions from the partnership,
since repayments of principal are not deductible for federal income tax
purposes. In addition, interest on the loans will not be deductible unless the
loans are bona fide loans that will not be treated by the IRS as capital
contributions to the partnership by the managing general partner or its
affiliates in light of all of the surrounding facts and circumstances.

PARTNERSHIP ORGANIZATION AND OFFERING COSTS
Expenses connected with the offer and sale of units in a partnership, such as
the dealer-manager fee, sales commissions, and other selling expenses,
professional fees, and printing costs, which are charged under the partnership
agreement 100% to the managing general partner as organization and offering
costs, are not deductible. Although expenses incident to the creation of a
partnership may be amortized over a period of not less than 180 months, these
expenses also will be paid by the managing general partner as part of each
partnership's organization costs. Thus, any related deductions, which the
managing general partner does not anticipate will be material in amount as
compared to the total amount of subscription proceeds of each partnership, will
be allocated to the managing general partner.


TAX ELECTIONS
Each partnership may elect to adjust the basis of its property on the transfer
of a unit in the partnership by sale or exchange or on the death of an investor,
and on the distribution of property (other than money) by the partnership to an
investor (the ss.754 election). If the ss.754 election is made, transferees of
the units are treated, for purposes of depreciation and gain, as though they had
acquired a direct interest in the partnership assets and the partnership is
treated for these purposes, on distributions to the investors, as though it had
newly acquired an interest in the partnership assets and therefore acquired a
new cost basis for the assets. Any election, once made, may not be revoked
without the consent of the IRS.

                                      116



In this regard, due to the complexities and added expense of the tax accounting
required to implement a ss.754 election to adjust the basis of a partnership's
property when units are sold, taking into account the limitations on the sale of
the partnership's units, the managing general partner anticipates that the
partnerships will not make the ss.754 election, although they reserve the right
to do so. Even if the partnerships do not make the ss.754 election, however, the
basis adjustment described above is mandatory under the Code with respect to the
transferee partner only, if at the time a unit is transferred by sale or
exchange, or on the death of an investor, the partnership's adjusted basis in
its property exceeds the fair market value of the property by more than $250,000
immediately after the transfer of the unit. Similarly, a basis adjustment is
mandatory under the Code if a partnership distributes property in-kind to a
partner and the sum of the partner's loss on the distribution and the basis
increase to the distributed property is more than $250,000. In this regard, a
partnership will not distribute its assets in-kind to its investors, except to a
liquidating trust or similar entity for the benefit of its investors, unless at
the time of the distribution its investors have been offered the election of
receiving in-kind property distributions, and you or any other investor in that
partnership accepts the offer after being advised of the risks associated with
direct ownership; or there are alternative arrangements in place which assure
that you and the other investors in that partnership will not, at any time, be
responsible for the operation or disposition of the partnership's properties.


If the basis of a partnership's assets must be adjusted as discussed above, the
primary effect on the partnership, other than the federal income tax
consequences discussed above, would be an increase in its administrative and
accounting expenses to make the required basis adjustments to its properties and
separately account for those adjustments after they are made. In this regard,
the partnerships will not make in-kind property distributions to their
respective investors except in the limited circumstances described above, and
the units have no readily available market and are subject to substantial
restrictions on their transfer. (See "Transferability of Units - Restrictions on
Transfer Imposed by the Securities Laws, the Tax Laws and the Partnership
Agreement.") These factors will tend to reduce the likelihood that a partnership
will be required to make mandatory basis adjustments to its properties. In
addition to the ss.754 election, each partnership may make various elections
under the Code for federal tax reporting purposes which could result in the
deductions of intangible drilling costs and depreciation, and the depletion
allowance, being treated differently for tax purposes than for accounting
purposes.

Also, under the Code "start-up expenditures" may be capitalized and amortized
over a 180-month period. The term "start-up expenditure" for this purpose
includes any amount:

     o    paid or incurred in connection with:

          o    investigating the creation of an active trade or business;

          o    creating an active trade or business, or

          o    any activity engaged in for profit and for the production of
               income before the day on which the active trade or business
               begins, in anticipation of that activity becoming an active trade
               or business; and

     o    which would be allowed as a deduction if paid or incurred in
          connection with the expansion of an existing business.

If it is ultimately determined by the IRS or the courts that any of a
partnership's expenses constituted start-up expenditures, that partnership's
deductions for those expenses, including your share of those deductions if you
are an investor in that partnership, would be amortized over the 180-month
period.

TAX RETURNS AND IRS AUDITS
The tax treatment of most partnership items is determined at the partnership,
rather than the partner level. Accordingly, the investors are required to treat
partnership items of the partnership in which they invest on their individual
federal income tax returns in a manner which is consistent with the treatment of
the partnership items on the partnership's federal information income tax
returns, unless they disclose to the IRS that their tax treatment of partnership
items on their personal federal income tax returns is different from their
partnership's tax treatment of those partnership items. In most cases, the IRS
must conduct an administrative determination as to partnership items at the
partnership level before conducting deficiency proceedings against a partner,
and the partners must file a request for an IRS administrative determination
with respect to partnership items before filing suit for any credit or refund.
Also, the period for assessing tax against you and the other investors because
of a partnership item may be extended by agreement between the IRS and the
managing general partner, which will serve as each partnership's representative
("Tax Matters Partner") in all administrative tax proceedings and tax litigation
conducted at the partnership level.

                                      117

The Tax Matters Partner may enter into a settlement on behalf of, and binding
on, any investor owning less than a 1% profits interest in a partnership if
there are more than 100 partners in the partnership, unless that investor timely
files a statement with the Secretary of the Treasury providing that the Tax
Matters Partner does not have authority to enter into a settlement agreement on
behalf of that investor. Based on its past experience, the managing general
partner anticipates that there will be more than 100 investors in each
partnership in which units are offered for sale. However, by executing the
Subscription Agreement you also are executing the partnership agreement if your
Subscription Agreement is accepted by the managing general partner. Under the
partnership agreement, you and the other investors in that partnership agree
that you will not form or exercise any right as a member of a notice group and
will not file a statement notifying the IRS that the Tax Matters Partner does
not have binding settlement authority. In addition, a partnership with at least
100 partners may elect to be governed under simplified tax reporting and audit
rules as an "electing large partnership." However, most limitations affecting
the calculation of the taxable income and tax credits of an electing large
partnership are applied at the partnership level and not the partner level.
Thus, the managing general partner does not anticipate that the partnerships
will make this election, although they reserve the right to do so.

All expenses of any tax proceedings involving a partnership and the managing
general partner acting as Tax Matters Partner, which might be substantial, will
be paid for by the partnership and not by the managing general partner from its
own funds. The managing general partner, however, is not obligated to contest
any adjustments made by the IRS to a partnership's federal information income
tax returns, even if the adjustment also would affect the individual federal
income tax returns of its investors. The managing general partner will notify
you and the other investors in your partnership of any IRS audits or other tax
proceedings involving your partnership, and will provide you and the other
investors any other information regarding the proceedings as may be required by
the partnership agreement or law.

TAX RETURNS. Your individual income tax returns are your responsibility. Each
partnership will provide its investors with the tax information applicable to
their investment in the partnership necessary to prepare their tax returns.

PROFIT MOTIVE, IRS ANTI-ABUSE RULE AND JUDICIAL DOCTRINES LIMITATIONS ON
DEDUCTIONS
Your ability to deduct your share of your partnership's deductions could be
limited or lost if the partnership lacks the appropriate profit motive. The Code
creates a presumption that an activity is engaged in for profit if, in any three
of five consecutive taxable years, the gross income derived from the activity
exceeds the deductions attributable to the activity. Thus, if your partnership
fails to show a profit in at least three out of five consecutive years this
presumption will not be available and the possibility that the IRS could
successfully challenge the partnership deductions claimed by you would be
substantially increased. The fact that the possibility of ultimately obtaining
profits is uncertain, standing alone, does not appear under the Treasury
Regulations to be sufficient grounds for the denial of losses. Also, if a
principal purpose of a partnership is to reduce substantially the partners'
federal income tax liability in a manner that is inconsistent with the intent of
the partnership rules of the Code, based on all the facts and circumstances, the
IRS is authorized under Treasury Regulation ss.1.701-2 to remedy the abuse.
Finally, under potentially relevant judicial doctrines including the step
transaction, business purpose, economic substance, substance over form, and sham
transaction doctrines, tax deductions and tax credits from a transaction,
including each partnership's deduction for intangible drilling costs in 2006,
will be disallowed if your partnership is found by the IRS or the courts, to
have no economic substance apart from the tax benefits.

With respect to these issues, special counsel has given its opinions that the
partnerships will possess the requisite profit motive, and the IRS anti-abuse
rule in Treas. Reg. ss.1.701-2 and the potentially relevant judicial doctrines
listed above will not have a material adverse effect on the tax consequences of
an investment in a partnership by a typical investor as described in special
counsel's opinions. These opinions are based in part on the results of the
previous partnerships sponsored by the managing general partner as set forth in
"Prior Activities" and the managing general partner's representations. These
representations include that each partnership will be operated as described in
this prospectus (see "Management" and "Proposed Activities") and the principal
purpose of each partnership is to locate, produce and market natural gas and oil
on a profitable basis to its investors, apart from tax benefits, as described in
this prospectus. These representations are supported by the information
concerning the partnerships' proposed drilling areas in "Proposed Activities,"
and the geological evaluations and other information for the specific prospects
proposed to be drilled by Atlas America Public #15-2006(B) L.P. included in
Appendix A to this prospectus, which represent a portion of the prospects to be
drilled if that partnership's targeted maximum subscription proceeds of $125
million are received (which is not binding on the partnership) as described in
"Terms of the Offering - Subscription to a Partnership." Also, the managing
general partner has represented that Appendix A in this prospectus will be
supplemented or amended to cover a portion of the specific prospects proposed to
be drilled by Atlas America Public #15-2006(C) L.P. if units in that partnership
are offered to prospective investors.


                                      118

FEDERAL INTEREST AND TAX PENALTIES
Taxpayers must pay tax and interest on underpayments of federal income taxes and
the Code contains various penalties, including penalties for negligence and
substantial valuation misstatements with respect to their individual federal
income tax returns. In addition, there is a penalty equal to 20% of the amount
of a substantial understatement of federal income tax liability. An
understatement occurs if the correct income tax, as finally determined by the
IRS or the courts, exceeds the income tax liability actually shown on the
taxpayer's federal income tax return. An understatement on a non-corporate
taxpayer's federal income tax return is substantial if it exceeds the greater of
10% of the correct tax, or $5,000. A non-corporate taxpayer may avoid this
penalty if the understatement was not attributable to a "tax shelter," and there
is or was substantial authority for the taxpayer's tax treatment of the item
that caused the understatement, or if the relevant facts were adequately
disclosed on the taxpayer's individual federal income tax return or a statement
attached to the return and the taxpayer had a "reasonable basis" for the tax
treatment of that item. In the case of an understatement that is attributable to
a "tax shelter," however, which may include each of the partnerships for this
purpose, the penalty may be avoided by a non-corporate taxpayer only if there
was reasonable cause for the underpayment and the taxpayer acted in good faith,
or there is or was substantial authority for the taxpayer's treatment of the
item that caused the understatement, and the taxpayer reasonably believed that
his or her treatment of the item on his individual federal income tax return was
more likely than not the proper treatment.

For purposes of this penalty, the term "tax shelter" includes a partnership if a
significant purpose of the partnership is the avoidance or evasion of federal
income tax. Because the IRS has not explained what a "significant" purpose of
avoiding or evading federal income taxes means, special counsel cannot give an
opinion as to whether the partnerships are "tax shelters" as defined by the Code
for purposes of this penalty.

In addition, there is a 20% penalty for reportable transaction understatements
of federal income taxes on a taxpayer's individual federal income tax return for
any tax year. However, if the disclosure rules for reportable transactions under
the Code and the Regulations are not met by the taxpayer, this penalty is
increased from 20% to 30%, and a "reasonable cause" exception to the penalty
which is set forth in ss.6664(d) of the Code will not be available to the
taxpayer. Under Treasury Regulation ss.1.6011-4, a taxpayer who participates in
a reportable transaction in any taxable year must attach to his individual
federal income tax return IRS Form 8886 "Reportable Transaction Disclosure
Statement," and file it with the IRS as directed in the Regulation, in order to
comply with the disclosure rules.

A tax item is subject to the reportable transaction rules if the tax item is
attributable to:


     o    any listed transaction, which is a transaction that is the same as, or
          substantially similar to, a transaction that the IRS has publicly
          pronounced to be a tax avoidance transaction; or

     o    any of four additional types of reportable transactions, if a
          significant purpose of the transaction is federal income tax avoidance
          or evasion.


                                      119


A "loss transaction" is one type of reportable transaction, but only if a
"significant" purpose of the transaction is federal income tax avoidance or
evasion. As set forth above, special counsel cannot give an opinion with respect
to whether or not each partnership has a "significant" purpose of avoiding or
evading federal income taxes, because the IRS has not explained what that phrase
means for purposes of this penalty. Under the Treasury Regulations, there is a
loss transaction if a partnership or any of its noncorporate partners claims a
loss under ss.165 of the Code of at least $2 million, in the aggregate, in any
taxable year of the partnership, or at least $4 million, in the aggregate, over
the partnership's first six years. In this regard, however, special counsel has
given its opinion that the partnerships are not, and should not be in the
future, reportable transactions under the Code, based in part on the managing
general partner's representation that each partnership's total abandonment
losses under ss.165 of the Code, such as losses for the abandonment by a
partnership of:

o        wells drilled which are nonproductive (i.e. a "dry hole"); and


     o    productive wells which have been operated until their commercial
          natural gas and oil reserves have been depleted;


will be less than $2 million, in the aggregate, in any taxable year of each
partnership and less than $4 million, in the aggregate, during each
partnership's first six taxable years.

STATE AND LOCAL TAXES
Each partnership will operate in states and localities which may impose a tax on
it, or on you and the partnership's other investors, based on the partnership's
assets or its income. Each partnership also may be subject to state income tax
withholding requirements on its income whether or not the revenues that created
the income are distributed to its investors. Deductions and credits, including
federal marginal well production credits, if any, which may be available to you
for federal income tax purposes, may not be available to you for state or local
income tax purposes. If you reside in a state or locality that imposes income
taxes on its residents, you likely will be required under those income tax laws
to include your share of your partnership's net income or net loss in
determining your reportable income for state or local tax purposes in the
jurisdiction in which you reside. To the extent that you pay tax to another
state because of partnership operations within that state, you may be entitled
to a deduction or credit against tax owed to your state of residence with
respect to the same income. Also, due to a partnership's operations in a state
or local jurisdiction, state or local estate or inheritance taxes may be payable
on the death of an investor in addition to taxes imposed by his own domicile.

Each partnership's units may be sold in all 50 states and the District of
Columbia and it is not practical for special counsel to evaluate the many
different state and local tax laws that may affect one or more of a
partnership's investors with respect to their investment in the partnership. You
are urged to seek advice based on your particular circumstances from an
independent tax advisor to determine the effect state and local taxes, including
gift and death taxes as well as income taxes, may have on you in connection with
an investment in a partnership.

SEVERANCE AND AD VALOREM (REAL ESTATE) TAXES
Each partnership may incur various ad valorem or severance taxes imposed by
state or local taxing authorities on its natural gas and oil wells and/or
natural gas and oil production from the wells. These taxes will reduce the
amount of each partnership's cash available for distribution to you and its
other investors.


SOCIAL SECURITY BENEFITS AND SELF-EMPLOYMENT TAX
A limited partner's share of income or loss from a partnership is excluded from
the definition of "net earnings from self-employment." No increased benefits
under the Social Security Act will be earned by limited partners and if any
limited partners are currently receiving Social Security benefits, their shares
of partnership taxable income will not be taken into account in determining any
reduction in benefits because of "excess earnings."

                                      120



An investor general partner's share of income or loss from a partnership will
constitute "net earnings from self-employment" for these purposes. The ceiling
for social security tax of 12.4% in 2006 is $94,200. There is no ceiling for
medicare tax of 2.9%. Self-employed individuals can deduct one-half of their
self-employment tax.


FARMOUTS
Under a farmout by a partnership, if a property interest, other than an interest
in the drilling unit assigned to the partnership well in question, is earned by
the farmee (anyone other than the partnership) from the farmor (the partnership)
as a result of the farmee drilling or completing the well, then the farmee must
recognize income equal to the fair market value of the outside interest earned,
and the farmor must recognize gain or loss on a deemed sale equal to the
difference between the fair market value of the outside interest and the
farmor's tax basis in the outside interest. Neither the farmor nor the farmee
would have received any cash to pay the tax. The managing general partner has
represented that it will attempt to eliminate or reduce any gain to a
partnership from a farmout, if any. However, if the IRS claims that a farmout by
a partnership results in taxable income to the partnership and its position is
ultimately sustained, you and the other investors in that partnership would be
required to include your share of the resulting taxable income on your
individual income tax returns, even though the partnership and you and the other
investors in that partnership received no cash from the farmout.

FOREIGN PARTNERS
Each partnership will be required to withhold and pay income tax to the IRS at
the highest rate under the Code applicable to partnership income allocable to
its foreign investors, even if no cash distributions are made to them. In the
event of overwithholding, a foreign investor must seek a refund on his
individual United States federal income tax return. For withholding purposes, a
foreign investor means an investor who is not a United States person and
includes a nonresident alien individual, a foreign corporation, a foreign
partnership, and a foreign trust or estate, unless the investor has certified to
his partnership the investor's status as a U.S. person on Form W-9 or any other
form permitted by the IRS for that purpose.

Foreign investors are urged to seek advice based on their particular
circumstances from an independent tax advisor regarding the applicability of
these rules and the other tax consequences of an investment in a partnership to
them.

ESTATE AND GIFT TAXATION

There is no federal tax on lifetime or testamentary transfers of property
between spouses. The gift tax annual exclusion amount is $12,000 per donee in
2006, which will be adjusted in subsequent years for inflation. Under the
Economic Growth and Tax Relief Reconciliation Act of 2001 (the "2001 Tax Act"),
the maximum estate and gift tax rate of 46% in 2006 will be reduced to 45% from
2007 through 2009. Estates of $2.0 million or less in 2006, which increases to
estates of $3.5 million or less in 2009, are not subject to federal estate tax
to the extent those exemption amounts (i.e., unified credit amounts) were not
previously used by the decedent to reduce gift taxes on any lifetime gifts in
excess of the applicable annual exclusion amount for gifts. Under the 2001 Tax
Act, the federal estate tax will be repealed in 2010, and the maximum gift tax
rate in 2010 will be 35%. In 2011, however, the federal estate and gift taxes
are scheduled to be reinstated under the rules in effect before the 2001 Tax Act
was enacted.


CHANGES IN THE LAW
Your tax benefits from an investment in a partnership may be affected by changes
in the tax laws. For example, in 2003 the top four federal income tax brackets
for individuals were reduced through December 31, 2010, including reducing the
top bracket to 35% from 38.6%. The lower federal income tax rates will reduce to
some degree the amount of taxes you can save by virtue of your share of your
partnership's deductions for intangible drilling costs, depletion and
depreciation, and marginal well production credits, if any. On the other hand,
the lower federal income tax rates also will reduce the amount of federal income
tax liability incurred by you on your share of your partnership's net income.
However, the federal income tax brackets discussed above could be changed again,
even before 2011, and other changes in the tax laws could be made which would
affect your tax benefits from an investment in a partnership.

                                      121


You are urged to seek advice based on your particular circumstances from an
independent tax advisor with respect to the impact of recent federal tax
legislation on an investment in a partnership and the status of federal and
state legislative, regulatory or administrative tax developments and tax
proposals and their potential effect on the tax consequences to you of an
investment in a partnership.

                        SUMMARY OF PARTNERSHIP AGREEMENT

The rights and obligations of the managing general partner and you and the other
investors are governed by the form of partnership agreement, a copy of which
attached as Exhibit (A) to this prospectus. You are urged to thoroughly review
the partnership agreement before you decide to invest in a partnership. The
following is a summary of the material provisions in the partnership agreement
that are not covered elsewhere in this prospectus. Thus, this prospectus
summarizes all of the material provisions of the partnership agreement.

LIABILITY OF LIMITED PARTNERS
Each partnership will be governed by the Delaware Revised Uniform Limited
Partnership Act. If you invest as a limited partner, then generally you will not
be liable to third-parties for the obligations of your partnership unless you:

     o    also invest as an investor general partner;

     o    take part in the control of the partnership's business in addition to
          the exercise of your rights and powers as a limited partner; or

     o    fail to make a required capital contribution to the extent of the
          required capital contribution.

In addition, you may be required to return any distribution you receive if you
knew at the time the distribution was made that it was improper because it
rendered the partnership insolvent.

AMENDMENTS
Amendments to the partnership agreement of a partnership may be proposed in
writing by:

     o    the managing general partner and adopted with the consent of investors
          whose units equal a majority of the total units in the partnership; or

     o    investors whose units equal 10% or more of the total units in the
          partnership and adopted by an affirmative vote of investors whose
          units equal a majority of the total units in the partnership.

The partnership agreement of each partnership may also be amended by the
managing general partner without the consent of the investors for certain
limited purposes. However, an amendment that materially and adversely affects
the investors can only be made with the consent of the affected investors.

NOTICE
The following provisions apply regarding notices:

     o    when the managing general partner gives you and other investors notice
          it begins to run from the date of mailing the notice and is binding
          even if it is not received;

     o    the notice periods are frequently quite short, a minimum of 22
          calendar days, and apply to matters that may seriously affect your
          rights; and

     o    if you fail to respond in the specified time to the managing general
          partner's second request for approval of or concurrence in a proposed
          action, then you will conclusively be deemed to have approved the
          action unless the partnership agreement expressly requires your
          affirmative approval.

                                      122


VOTING RIGHTS
Other than as set forth below, you generally will not be entitled to vote on any
partnership matters at any partnership meeting. However, at any time investors
whose units equal 10% or more of the total units in a partnership may call a
meeting to vote, or vote without a meeting, on the matters set forth below
without the concurrence of the managing general partner. On the matters being
voted on you are entitled to one vote per unit or if you own a fractional unit
that fraction of one vote equal to the fractional interest in the unit.
Investors whose units equal a majority of the total units in a partnership may
vote to:

     o    dissolve the partnership;

     o    remove the managing general partner and elect a new managing general
          partner;

     o    elect a new managing general partner if the managing general partner
          elects to withdraw from the partnership;

     o    remove the operator and elect a new operator;

     o    approve or disapprove the sale of all or substantially all of the
          partnership assets;

     o    cancel any contract for services with the managing general partner,
          the operator, or their affiliates without penalty on 60 days notice;
          and

     o    amend the partnership agreement; provided however, any amendment may
          not:

          o    without the approval of you or the managing general partner
               increase the duties or liabilities of you or the managing general
               partner or increase or decrease the profits or losses or required
               capital contribution of you or the managing general partner; or

          o    without the unanimous approval of all investors in the
               partnership affect the classification of partnership income and
               loss for federal income tax purposes.

The managing general partner, its officers, directors, and affiliates may also
subscribe for units in each partnership on a discounted basis, and they may vote
on all matters other than:

     o    the issues set forth above concerning removing the managing general
          partner and operator; and

     o    any transaction between the managing general partner or its affiliates
          and the partnership.

Any units owned by the managing general partner and its affiliates will not be
included in determining the requisite number of units necessary to approve any
partnership matter on which the managing general partner and its affiliates may
not vote or consent.

ACCESS TO RECORDS
You will have access to all records of your partnership at any reasonable time
on adequate notice. However, logs, well reports, and other drilling and
operating data may be kept confidential for reasonable periods of time. Your
ability to obtain the list of investors is subject to additional requirements
set forth in the partnership agreement.

WITHDRAWAL OF MANAGING GENERAL PARTNER
After 10 years the managing general partner may voluntarily withdraw as managing
general partner of a partnership for any reason by giving 120 days' written
notice to you and the other investors in the partnership. Although the
withdrawing managing general partner is not required to provide a substitute
managing general partner, a new managing general partner may be substituted by
the affirmative vote of investors whose units equal a majority of the total
units in the partnership. If the investors, however, choose not to continue the
partnership and do not select a substitute managing general partner, then the
partnership would terminate and dissolve which could result in adverse tax and
other consequences to you.


                                      123


Also, the managing general partner may assign its general partner interest in
each partnership to its affiliates, and it may withdraw a property interest in
the form of a working interest in the partnership's wells equal to or less than
its revenue interest if the withdrawal is:

     o    to satisfy the bona fide request of its creditors; or

     o    approved by investors in the partnership whose units equal a majority
          of the total units.

(See "Management - Managing General Partner and Operator" and "Conflicts of
Interest - Conflicts Regarding the Managing General Partner Withdrawing or
Assigning an Interest."


RETURN OF SUBSCRIPTION PROCEEDS IF FUNDS ARE NOT INVESTED IN TWELVE MONTHS
Although the managing general partner anticipates that each partnership will
spend all of its subscription proceeds soon after the offering of the
partnership closes, each partnership will have 12 months in which to use or
commit funds to drilling activities. If within the 12-month period the
partnership has not used or committed for use all the subscription proceeds,
then the managing general partner will distribute the remaining subscription
proceeds to you and the other investors in the partnership in accordance with
your subscription proceeds as a return of capital.

                   SUMMARY OF DRILLING AND OPERATING AGREEMENT

The managing general partner will serve as the operator under the drilling and
operating agreement, Exhibit (II) to the partnership agreement. The operator may
be replaced at any time on 60 days' advance written notice by the managing
general partner acting on behalf of a partnership on the affirmative vote of
investors whose units equal a majority of the total units in the partnership.
You are urged to thoroughly review the drilling and operating agreement before
you decide whether to invest in a partnership. The following is a summary of the
material provisions in the drilling and operating agreement that are not covered
elsewhere in this prospectus. Thus, this prospectus summarizes all of the
material provisions of the drilling and operating agreement.

The drilling and operating agreement includes a number of material provisions,
including, without limitation, those set forth below.

     o    The operator's right to resign after five years.

     o    The operator's right beginning one year after a partnership well
          begins producing to retain $200 per month to cover future plugging and
          abandonment costs of the well.

     o    The grant of a first lien and security interest in the wells and
          related production to secure payment of amounts due to the operator by
          a partnership.

     o    The prescribed insurance coverage to be maintained by the operator.

     o    Limitations on the operator's authority to incur extraordinary costs
          with respect to producing wells in excess of $5,000 per well.

     o    Restrictions on the partnership's ability to transfer its interest in
          fewer than all wells unless the transfer is of an equal undivided
          interest in all wells.

     o    The limitation of the operator's liability to a partnership except for
          the operator's:

          o    violations of law;

                                      124


          o    negligence or misconduct by it, its employees, agents or
               subcontractors; or

          o    breach of the drilling and operating agreement.

     o    The excuse for nonperformance by the operator due to force majeure
          which generally means acts of God, catastrophes and other causes which
          preclude the operator's performance and are beyond its control.

                              REPORTS TO INVESTORS

Under the partnership agreement for each partnership you and certain state
securities commissions will be provided the reports and information set forth
below for your partnership, which your partnership will pay as a direct cost.

     o    Beginning with the calendar year in which your partnership closes, you
          will be provided an annual report within 120 days after the close of
          the calendar year, and beginning with the following calendar year, a
          report within 75 days after the end of the first six months of its
          calendar year, containing at least the following information.

          o    Audited financial statements of the partnership prepared on an
               accrual basis in accordance with generally accepted accounting
               principles with a reconciliation for information furnished for
               income tax purposes. Independent certified public accountants
               will audit the financial statements to be included in the annual
               report, but semiannual reports will not be audited.


          o    A summary of the total fees and compensation paid by the
               partnership to the managing general partner, the operator, and
               their affiliates, including the percentage that the annual
               nonaccountable, fixed payment reimbursement for administrative
               costs bears to annual partnership revenues. In this regard, the
               independent certified public accountant will provide written
               attestation annually, which will be included in the annual
               report, that the method used to make allocations was consistent
               with the method described in ss.4.04(a)(2)(c) of the partnership
               agreement and that the total amount of costs allocated did not
               materially exceed the amounts actually incurred by the managing
               general partner.


               If the managing general partner subsequently decides to allocate
               expenses in a manner different from that described in
               ss.4.04(a)(2)(c) of the partnership agreement, then the change
               must be reported to you and the other investors with an
               explanation of the reason for the change and the basis used for
               determining the reasonableness of the new allocation method.

          o    A description of each prospect owned by the partnership,
               including the cost, location, number of acres, and the interest.

          o    A list of the wells drilled or abandoned by the partnership
               indicating:

               o    whether each of the wells has or has not been completed; and

               o    a statement of the cost of each well completed or abandoned.

          o    A description of all farmouts, farmins, and joint ventures.

          o    A schedule reflecting:

               o    the total partnership costs;

                                      125


               o    the costs paid by the managing general partner and the costs
                    paid by the investors;

               o    the total partnership revenues; and

               o    the revenues received or credited to the managing general
                    partner and the revenues received or credited to you and the
                    other investors.

     o    On request the managing general partner will provide you the
          information specified by Form 10-Q (if that report is required to be
          filed with the SEC) within 45 days after the close of each quarterly
          fiscal period. Also, this information is available at the SEC website
          www.sec.gov.

     o    By March 15 of each year you will receive the information that is
          required for you to file your federal and state income tax returns.

     o    Beginning with the second calendar year after your partnership closes,
          and every year thereafter, you will receive a computation of the
          partnership's total natural gas and oil proved reserves and its dollar
          value. The reserve computations will be based on engineering reports
          prepared by the managing general partner and reviewed by an
          independent expert.

                               PRESENTMENT FEATURE


Beginning with the fifth calendar year after your partnership closes, you and
the other investors in your partnership may present your units to the managing
general partner to purchase your units. However, you are not required to offer
your units to the managing general partner, and you may receive a greater return
if you retain your units. The managing general partner will not purchase less
than one unit unless the fractional unit represents your entire interest.


The managing general partner has no obligation or intention to establish a
reserve to satisfy the presentment obligation and it may immediately suspend the
presentment obligation by notice to you if it determines, in its sole
discretion, that it:

     o    does not have the necessary cash flow; or

     o    cannot borrow funds for this purpose on terms it deems reasonable.

If fewer than all units presented at any time are to be purchased by the
managing general partner, then the units to be purchased will be selected by
lot.

The managing general partner's obligation to purchase the units presented may be
discharged for its benefit by a third-party or an affiliate. If you sell your
unit it will be transferred to the party who pays for it, and you will be
required to deliver an executed assignment of your unit along with any other
documents that the managing general partner requests. Your presentment is
subject to the following conditions:

     o    the managing general partner will not purchase more than 5% of the
          units in a partnership in any calendar year;

     o    the presentment must be within 120 days of the partnership reserve
          report discussed below;

     o    in accordance with Treas. Reg. ss.1.7704-1(f) the purchase may not be
          made by the managing general partner until at least 60 calendar days
          after you notify the partnership in writing of your intent to present
          your unit; and

     o    the purchase will not be considered effective until the presentment
          price has been paid to you in cash.

                                      126


The amount attributable to a partnership's natural gas and oil reserves will be
determined based on the last reserve report prepared by the managing general
partner and reviewed by an independent expert. Beginning with the second
calendar year after your partnership closes and every year thereafter, the
managing general partner will estimate the present worth of future net revenues
attributable to your partnership's interest in proved reserves. In making this
estimate, the managing general partner will use:

     o    a 10% discount rate;

     o    a constant oil price; and

     o    base natural gas prices on the existing natural gas contracts at the
          time of the presentment.

Your presentment price will be based on your share of your partnership's net
assets and liabilities as described below, based on the ratio that your number
of units bears to the total number of units in your partnership. The presentment
price will include the sum of the following partnership items:

     o    an amount based on 70% of the present worth of future net revenues
          from the proved reserves determined as described above;

     o    cash on hand;

     o    prepaid expenses and accounts receivable, less a reasonable amount for
          doubtful accounts; and

     o    the estimated market value of all assets not separately specified
          above, determined in accordance with standard industry valuation
          procedures.

There will be deducted from the foregoing sum the following items:

     o    an amount equal to all debts, obligations, and other liabilities,
          including accrued expenses; and

     o    any distributions made to you between the date of the request and the
          actual payment. However, if any cash distributed, after the
          presentment request, was derived from the sale of oil, natural gas, or
          a producing property, for purposes of determining the reduction of the
          presentment price the distributions will be discounted at the same
          rate used to take into account the risk factors employed to determine
          the present worth of the partnership's proved reserves.

The amount may be further adjusted by the managing general partner for estimated
changes from the date of the reserve report to the date of payment of the
presentment price to you because of the following:

     o    the production or sales of, or additions to, reserves and lease and
          well equipment, sale or abandonment of leases, and similar matters
          occurring before the presentment request; and

     o    any of the following occurring before payment of the presentment price
          to you;

          o    changes in well performance;

          o    increases or decreases in the market price of oil, natural gas,
               or other minerals;

          o    revision of regulations relating to the importing of
               hydrocarbons; and

          o    changes in income, ad valorem, and other tax laws such as
               material variations in the provisions for depletion; and

                                      127


          o    similar matters.


As of January 13, 2006, approximately 200 units have been presented to the
managing general partner for purchase in its previous 51 limited partnerships.


                            TRANSFERABILITY OF UNITS

RESTRICTIONS ON TRANSFER IMPOSED BY THE SECURITIES LAWS, THE TAX LAWS AND THE
PARTNERSHIP AGREEMENT
Your ability to sell or otherwise transfer your units in your partnership is
restricted by the securities laws, the tax laws, and the partnership agreement
as described below. Also, the transfer may create negative tax consequences to
you as described in "Federal Income Tax Consequences - Disposition of Units."

First, under the tax laws you will not be able to sell, assign, exchange, or
transfer your unit if it would, in the opinion of counsel for the partnership,
result in the following:

          o    the termination of your partnership for tax purposes; or

          o    your partnership being treated as a "publicly traded" partnership
               for tax purposes.

Second, under the partnership agreement transfers are subject to the following
limitations:

          o    except as provided by operation of law, the partnership will
               recognize the transfer of only one or more whole units unless you
               own less than a whole unit, in which case your entire fractional
               interest must be transferred;

          o    the costs and expenses associated with the transfer must be paid
               by the person transferring the unit;

          o    the form of transfer must be in a form satisfactory to the
               managing general partner; and

          o    the terms of the transfer must not contravene those of the
               partnership agreement.


Your transfer of a unit will not relieve you of your responsibility for any
obligations related to the units under the partnership agreement, grant rights
under the partnership agreement as among your transferees to more than one party
unanimously designated by the transferees to the managing general partner, nor
require an accounting by the managing general partner. Any transfer when the
assignee of the unit does not become a substituted partner as described below in
"- Conditions to Becoming a Substitute Partner," will be effective as of
midnight of the last day of the calendar month in which it is made or, at the
managing general partner's election, 7:00 A.M. of the following day. Also, you
will not be able to sell, assign, pledge, hypothecate, or transfer your unit if
the managing general partner requires, in its sole discretion, that you must
provide an opinion of counsel acceptable to the managing general partner that
the registration and qualification under any applicable federal or state
securities laws are not required.


CONDITIONS TO BECOMING A SUBSTITUTE PARTNER
An assignee of a unit will not be entitled to any of the rights granted to a
partner under the partnership agreement, other than the right to receive all or
part of the share of the profits, losses, income, gain, credits and cash
distributions or returns of capital to which his assignor would otherwise be
entitled, unless the assignee becomes a substituted partner in accordance with
the provisions set forth below. The conditions to become a substitute partner
are as follows:

          o    the assignor gives the assignee the right;

          o    the assignee pays all costs and expenses incurred in connection
               with the substitution; and

                                      128



          o    the assignee executes and delivers, in a form acceptable to the
               managing general partner, the instruments necessary to establish
               that a legal transfer has taken place and to confirm his
               agreement to be bound by all terms and provisions of the
               partnership agreement.


A substitute partner is entitled to all of the rights of full ownership of the
assigned units, including the right to vote. Each partnership will amend its
records at least once each calendar quarter to effect the substitution of
substituted partners.

                              PLAN OF DISTRIBUTION

COMMISSIONS
The units in each partnership will be offered on a "best efforts" basis by
Anthem Securities, which is an affiliate of the managing general partner, acting
as dealer-manager and by other selected registered broker/dealers which are
members of the NASD acting as selling agents. Anthem Securities was formed for
the purpose of serving as dealer-manager of partnerships sponsored by the
managing general partner and became an NASD member firm in April, 1997.


The dealer-manager will manage and oversee the offering of the units as
described above. Best efforts generally means that the dealer-manager and
selling agents will not guarantee that a certain number of units will be sold.
Units may also be sold by the officers and directors of the managing general
partner in those states where they are licensed or exempt from licensing.
Messrs. Kotek, Hollander and Atkinson and Ms. Bleichmar and Ms. Black, who are
associated with Anthem Securities, will not make any offers or sales under the
SEC safe harbor from broker/dealer registration provided by SEC Rule 3a4-1 under
the Securities Exchange Act of 1934 (the "Act"), although they may do so as
associated persons of Anthem Securities. Also, all offers and sales of units by
the managing general partner's remaining officers and directors will be made
under the SEC safe harbor from broker/dealer registration provided by Rule
3a4-1. In this regard, none of the remaining officers and directors of the
managing general partner:


          o    is subject to a statutory disqualification, as that term is
               defined in Section 3(a)(39) of the Act, at the time of his
               participation;

          o    is compensated in connection with his participation by the
               payment of commissions or other remuneration based either
               directly or indirectly on transactions in securities; and

          o    is at the time of his participation an associated person of a
               broker or dealer.

Also, each of the remaining officers and directors:

          o    performs, or is intended primarily to perform at the end of the
               offering, substantial duties for or on behalf of the managing
               general partner otherwise than in connection with transactions in
               securities;

          o    was not a broker or dealer, or an associated person of a broker
               or dealer, within the preceding 12 months; and

          o    will not participate in selling an offering of securities for any
               issuer more than once every 12 months, with the understanding
               that for securities issued pursuant to Rule 415 under Securities
               Act of 1933, the 12 month period begins with the last sale of any
               security included within one Rule 415 registration.

Subject to the exceptions described below, the dealer-manager will receive on
each unit sold:

          o    a 2.5% dealer-manager fee;

          o    a 7% sales commission;

                                      129


          o    an up to .5% reimbursement of the selling agent's bona fide due
               diligence expenses; and

          o    a .5% accountable reimbursement for permissible non-cash
               compensation. Under Rule 2810 of the NASD Conduct Rules, non-cash
               compensation means any form of compensation received in
               connection with the sale of the units that is not cash
               compensation, including but not limited to merchandise, gifts and
               prizes, travel expenses, meals and lodging. Permissible non-cash
               compensation includes the following:

               o    an accountable reimbursement for training and education
                    meetings for associated persons of the selling agents;

               o    gifts that do not exceed $100 per year and are not
                    preconditioned on achievement of a sales target;

               o    an occasional meal, a ticket to a sporting event or the
                    theater, or comparable entertainment which is neither so
                    frequent nor so extensive as to raise any question of
                    propriety and is not preconditioned on achievement of a
                    sales target; and

               o    contributions to a non-cash compensation arrangement between
                    a selling agent and its associated persons, provided that
                    neither the managing general partner nor the dealer-manager
                    directly or indirectly participates in the selling agent's
                    organization of a permissible non-cash compensation
                    arrangement.

All of the reimbursement of the selling agents' bona fide due diligence expenses
and generally all of the 7% sales commission will be reallowed to the selling
agents. With respect to the up to .5% reimbursement of a selling agent's bona
fide due diligence expenses, any bill presented by a selling agent to the
dealer-manager for reimbursement of costs associated with its due diligence
activities must be for actual costs, including overhead, incurred by the selling
agent and may not include a profit margin. It is the responsibility of the
managing general partner and the dealer-manager to ensure compliance with the
above guideline. Although the dealer-manager is not required to obtain an
itemized expense statement before paying out due diligence expenses, any bill
for due diligence submitted by the selling agent to the dealer-manager must be
based on the selling agent's actual expenses incurred in conducting due
diligence. If the dealer-manager receives a non-itemized bill for due diligence
that it has reason to question, then it has the obligation to ensure compliance
by requesting an itemized statement to support the bill submitted by the selling
agent. If the due diligence bill cannot be justified, any excess over actual due
diligence expenses that is paid is considered by the NASD to be undisclosed
underwriting compensation and is required to be included within the 10%
compensation guideline under NASD Conduct Rule 2810, and reflected on the books
and records of the selling agent. However, if the selling agent provides the
dealer-manager an itemized bill for actual due diligence expenses which is in
excess of .5%, then the excess over .5% will not be included within the 10%
compensation guideline, but instead will be included within the 4.5%
organization and offering cost guideline under NASD Conduct Rule 2810.

The dealer-manager or managing general partner may make certain non-cash
compensation arrangements with the selling agents and their registered
representatives, which will be included in the accountable reimbursement for
permissible non-cash compensation. The dealer-manager is responsible for
ensuring that all permissible non-cash compensation arrangements comply with
Rule 2810 of the NASD Conduct Rules. For example, payments or reimbursements by
the dealer-manager or the managing general partner may be made in connection
with meetings held by the dealer-manager or the managing general partner for the
purpose of training or education of registered representatives of a selling
agent only if the following conditions are met:

     o    the registered representative obtains his selling agent's prior
          approval to attend the meeting and attendance by the registered
          representative is not conditioned by his selling agent on the
          achievement of a sales target;

     o    the location of the training and education meeting is appropriate to
          the purpose of the meeting as defined in NASD Conduct Rule 2810;

                                      130


     o    the payment or reimbursement is not applied to the expenses of guests
          of the registered representative;

     o    the payment or reimbursement by the dealer-manager or the managing
          general partner is not conditioned by the dealer-manager or the
          managing general partner on the achievement of a sales target; and

     o    the recordkeeping requirements are met.

The dealer-manager will retain any of the accountable reimbursement for
permissible non-cash compensation not reallowed to the selling agents.


The managing general partner is also using the services of wholesalers who are
employed by it or its affiliates and are registered through Anthem Securities.
The wholesalers include four Regional Marketing Directors, Mr. Bruce Bundy, Mr.
Robert Gourlay, Ms. Vicki Burbridge and Mr. Jim O'Mara. A portion of the 2.5%
dealer-manager fee will be reallowed to the affiliated wholesalers for
subscriptions obtained through their efforts, which includes expense
reimbursements to them and a salary to Mr. O'Mara in connection with the
offering. The dealer-manager will retain the remainder of the dealer-manager fee
not reallowed to the wholesalers, which may be used for such items as legal fees
associated with underwriting and salaries of dual employees of the
dealer-manager and the managing general partner which are required to be
included in underwriting compensation under NASD Conduct Rule 2810 as determined
jointly by the managing general partner and the dealer-manager.


The offering will be made in compliance with Rule 2810 of the NASD Conduct Rules
and all compensation, including non-cash compensation, to broker/dealers and
wholesalers, regardless of the source, will be limited to 10% of the gross
proceeds of the offering plus the .5% reimbursement for bona fide due diligence
expenses on each subscription. Also, the offering will be made in compliance
with Rule 2810(b)(2)(C) of the NASD Conduct Rules and the broker/dealers and
wholesalers will not execute a transaction for the purchase of units in a
discretionary account without the prior written approval of the transaction by
the customer. Finally, the offering will be conducted in compliance with SEC
Rule 15c2-4.

Subject to the following, you and the other investors will pay $10,000 per unit
and generally will share costs, revenues, and distributions in the partnership
in which you invest in proportion to your respective number of units. However,
the subscription price for certain investors will be reduced as set forth below:

     o    the subscription price for the managing general partner, its officers,
          directors, and affiliates, and investors who buy units through the
          officers and directors of the managing general partner, will be
          reduced by an amount equal to the 2.5% dealer-manager fee, the 7%
          sales commission, the .5% reimbursement for bona fide due diligence
          expenses, and the .5% accountable reimbursement for permissible
          non-cash compensation, which will not be paid with respect to these
          sales; and

     o    the subscription price for registered investment advisors and their
          clients, and selling agents and their registered representatives and
          principals, will be reduced by an amount equal to the 7% sales
          commission, which will not be paid with respect to these sales.

No more than 5% of the total units in each partnership may be sold with the
discounts described above. These investors who pay a reduced price for their
units generally will share in a partnership's costs, revenues, and distributions
on the same basis as the other investors who pay $10,000 per unit as discussed
in "Participation in Costs and Revenues - Allocation and Adjustments Among
Investors." Although the managing general partner and its affiliates may buy up
to 5% of the units, they do not currently anticipate buying any units. If they
do buy units, then those units will not be applied towards the minimum
subscription proceeds required for a partnership to begin operations.


To help assure an orderly market for the units, the managing general partner,
the dealer-manager and the selling agents may use such methods as they deem
appropriate to allocate units among interested investors if they anticipate that
demand for units will exceed the available supply, provided that no changes to
compensation may be made. These methods may include, but will not be limited to:

                                      131


     o    allocations of units to selling agents;

     o    priority acceptance of subscriptions from previous investors in
          partnerships sponsored by the managing general partner;

     o    priority treatment for investors whose subscriptions were declined by
          earlier partnerships sponsored by the managing general partner because
          the number of units available was not sufficient to accommodate their
          subscriptions; or

     o    any other methods as may be approved by the managing general partner.


After the minimum subscriptions are received in a partnership and the checks
have cleared the banking system, the dealer-manager fee and the sales
commissions will be paid to the dealer-manager and selling agents approximately
every two weeks until the offering closes.

INDEMNIFICATION

The dealer-manager is an underwriter as that term is defined in the 1933 Act and
the sales commissions and dealer-manager fees will be deemed underwriting
compensation. The managing general partner and the dealer-manager have agreed
to indemnify each other, and it is anticipated that the dealer-manager and each
selling agent will agree to indemnify each other against certain liabilities,
including liabilities under the 1933 Act.

                                 SALES MATERIAL


In addition to the prospectus, the managing general partner intends to use the
following sales material with the offering of the units:


     o    a flyer entitled "Atlas America Public #15-2005 Program";

     o    an article entitled "Tax Rewards with Oil and Gas Partnerships";

     o    a brochure of tax scenarios entitled "How an Investment in Atlas
          America Public #15-2005 Program Can Help Achieve an Investor's Tax
          Objectives";

     o    a booklet entitled "Outline of Tax Consequences of Oil and Gas
          Drilling Programs";

     o    a brochure entitled "Investment Insights - Tax Time";

     o    a brochure entitled "Frequently Asked Questions";

     o    a brochure entitled "The Drilling Process"; and

     o    possibly other supplementary materials.

The managing general partner has not authorized the use of other sales material
and the offering of units is made only by means of this prospectus. The sales
material is subject to the following considerations:

     o    it must be preceded or accompanied by this prospectus;

     o    it is not complete;


     o    it does not contain any information which is inconsistent with this
          prospectus; and


                                      132


     o    it should not be considered a part of or incorporated into this
          prospectus or the registration statement of which this prospectus is a
          part.

In addition, supplementary materials, including prepared presentations for group
meetings, must be submitted to the state administrators before they are used and
their use must either be preceded by or accompanied by a prospectus. Also, all
advertisements of, and oral or written invitations to, "seminars" or other group
meetings at which the units are to be described, offered, or sold will clearly
indicate the following:

     o    that the purpose of the meeting is to offer the units for sale;

     o    the minimum purchase price of the units;

     o    the suitability standards to be employed; and

     o    the name of the person selling the units.

Also, no cash, merchandise, or other items of value may be offered as an
inducement to you or any other prospective investor to attend the meeting. All
written or prepared audiovisual presentations, including scripts prepared in
advance for oral presentations to be made at the meetings, must be submitted to
the state administrators within a prescribed review period. These provisions,
however, will not apply to meetings consisting only of the registered
representatives of the selling agents.

You should rely only on the information contained in this prospectus in making
your investment decision. No one is authorized to provide you with information
that is different.

                                 LEGAL OPINIONS


Kunzman & Bollinger, Inc., has issued its opinion to the managing general
partner regarding the validity and due issuance of the units, including
assessibility, and its opinion on the material and any significant federal tax
consequences to individual typical investors in the partnerships. However, the
factual statements in this prospectus are those of the partnerships or the
managing general partner, and counsel has not given any opinions with respect to
any of the tax or other legal aspects of this offering except as expressly set
forth above.

             REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM


To the Partners
ATLAS AMERICA PUBLIC #15-2006 (B) L.P.
(A DELAWARE LIMITED PARTNERSHIP)

We have audited the accompanying balance sheet of Atlas America Public #15-2006
(B) L.P. (A Delaware Limited Partnership) as of February 3, 2006. This financial
statement is the responsibility of the Partnership's management. Our
responsibility is to express an opinion on this financial statement based on our
audit.

We conducted our audit in accordance with the standards of the Public Company
Accounting Oversight Board (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. The Partnership is not required to
have, nor were we engaged to perform an audit of its internal control over
financial reporting. Our audit included consideration of internal control over
financial reporting as a basis for designing audit procedures that are
appropriate in the circumstances, but not for the purpose of expressing an
opinion on the effectiveness of the Partnership's internal control over
financial reporting. Accordingly, we express no such opinion. An audit also
includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements, assessing the accounting principles
used and significant estimates made by management, as well as evaluating the
overall financial statement presentation. We believe that our audit provide a
reasonable basis for our opinion.

In our opinion, the financial statement referred to above presents fairly, in
all material respects, the financial position of Atlas America Public #15-2006
(B) L.P. as of February 3, 2006, in conformity with accounting principles
generally accepted in the United States of America.

                          NOTES TO FINANCIAL STATEMENT
                                FEBRUARY 3, 2006

1.       ORGANIZATION AND DESCRIPTION OF BUSINESS

         Atlas America Public #15-2006 (B) L.P. (the "Partnership") is a
         Delaware limited partnership in which Atlas Resources, Inc. ("Atlas
         Resources") of Pittsburgh, Pennsylvania (a second-tier wholly-owned
         subsidiary of Atlas America, Inc., a publicly traded company), will be
         Managing General Partner and Operator, and subscribers to units will be
         either Limited Partners or Investor General Partners depending upon
         their individual elections.

         The Partnership will be funded to drill development wells which are
         proposed to be located primarily in the Appalachian Basin located in
         western Pennsylvania, eastern and southern Ohio, western New York and
         north central Tennessee.

         Subscriptions at a cost of $10,000 per unit, subject to discounts for
         certain investors, generally will be sold using wholesalers and through
         broker-dealers including Anthem Securities, Inc., an affiliated
         company, which will receive on each unit sold to an investor, a 2.5%
         dealer-manager fee, a 7% sales commission, a .5% accountable
         reimbursement for permissible non-cash compensation, and up to a .5%
         reimbursement of the selling agents' bona fide due diligence expenses.
         Commencement of Partnership operations is subject to the receipt of
         minimum Partnership subscriptions of $2,000,000 (up to a maximum of
         $147,726,000) by December 31, 2006.

2.       SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

         BASIS OF ACCOUNTING

         The Partnership prepares its financial statements in accordance with
         accounting principles generally accepted in the United States of
         America.


                                      F-3


                     Atlas America Public #15-2006 (B) L.P.

                          NOTES TO FINANCIAL STATEMENT
                                FEBRUARY 3, 2006

2.       SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

         OIL AND GAS PROPERTIES

         The Partnership will use 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 will
         be capitalized. Depreciation and depletion will be 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 will be assessed periodically or whenever events or
         circumstances indicate that the carrying amount of these assets may not
         be recoverable. Proved properties will be assessed based on estimates
         of future cash flows.

         USE OF ESTIMATES

         The preparation of financial statements in conformity with accounting
         principles generally accepted in the United States of America 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.

3.       FEDERAL INCOME TAXES

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

         The Managing General Partner and the investor partners will participate

(1)      An amount equal to 90% of the subscription proceeds of investor
         partners in the partnership will be used to pay 100% of the intangible
         drilling costs incurred by the partnership in drilling and completing
         its wells.

(2)      An amount equal to 10% of the subscription proceeds of investor
         partners in the partnership will be used to pay a portion of the
         equipment costs incurred by the partnership in drilling and completing
         its wells. All equipment costs in excess of that amount will be charged
         to the Managing General Partner. Equipment proceeds, if any, will be
         credited in the same percentage in which the equipment costs were
         charged.

(3)      These costs will be charged to the parties in the same ratio as the
         related production revenues are being credited. These costs also
         include plugging and abandonment costs of the wells after the wells
         have been drilled and produced.

4.       PARTICIPATION IN REVENUES AND COSTS (CONTINUED)

(4)      Interest earned on subscription proceeds before the final closing of
         the partnership will be credited to investor partners' accounts and
         paid not later than the partnerships first cash distribution from
         operations. After the final closing of the partnership and until the
         subscription proceeds are invested in the partnership's natural gas and
         oil operations any interest income from temporary investments will be
         allocated pro rata to the investor partners providing the subscription
         proceeds. All other interest income, including interest earned on the
         deposit of operating revenues, will be credited as natural gas and oil
         production revenues are credited.

(5)      The managing general partner and the investor partners in the
         partnership will share in all of the partnership's other revenues in
         the same percentage as their respective capital contributions bear to
         the total partnership capital contributions except that the managing
         general partner will receive an additional 7% of the partnership
         revenues. However, the managing general partner's total revenue share
         may not exceed 40% of partnership revenues.

         The partnership will enter into a drilling and operating agreement with
         Atlas Resources to drill and complete all of the partnership wells at
         cost plus an unaccountable, fixed payment reimbursement of $15,000 per
         well for the investor partners' share of Atlas Resources' general and
         administrative overhead cost, plus 15%, which will be proportionately
         reduced if the partnership's working interest in a well is less than
         100%.

(6)      The actual allocation of partnership revenues between the managing
         general partner and the investor partners will vary from the allocation
         described in (5) above if a portion of the managing general partner's
         partnership net production revenues is subordinated as described in
         note 7.

5.       TRANSACTIONS WITH ATLAS RESOURCES AND ITS AFFILIATES

         The Partnership intends to enter into the following significant
         transactions with Atlas Resources and its affiliates as provider under
         the Partnership agreement:

         The partnership will enter into a drilling and operating agreement with
         Atlas Resources to drill and complete all of the Partnership wells at
         cost plus an unaccountable, fixed payment reimbursement to Atlas
         Resources of the investor partners' share of general and administrative
         overhead cost of $15,000 per well, plus 15%, which will be
         proportionately reduced if the Partnership's working interest in a well
         is less than 100%. The cost of the wells will include all ordinary and
         actual costs of drilling, testing and completing the wells.

5.       TRANSACTIONS WITH ATLAS RESOURCES AND ITS AFFILIATES (CONTINUED)

         Atlas Resources will receive an unaccountable, fixed payment
         reimbursement for its administrative costs at $75 per well per month,
         which will be proportionately reduced if the partnership's working
         interest in a well is less than 100%.

         Atlas Resources will receive well supervision fees for operating and
         maintaining the wells during production operations at a competitive
         rate (currently the competitive rate is $285 per well per month in the
         primary and secondary drilling areas). The well supervision fees will
         be proportionately reduced if the partnership's working interest in a
         well is less than 100%.

         Atlas Resources will charge the partnership a fee for gathering and
         transportation at a competitive rate (currently in the range of $.20 to
         $.70 per MCF in the primary and secondary drilling areas).

         Atlas Resources will contribute all the undeveloped leases necessary to
         cover each of the partnership's prospects and will receive a credit for
         its capital account in the partnership equal to the cost of the leases
         (approximately $8,411 per prospect which will be proportionately
         reduced if the Partnership's working interest in the prospect is less
         than 100%). As Managing General Partner, Atlas Resources will perform
         all administrative and management functions for the partnership
         including billing and collecting revenues and paying expenses. Atlas
         Resources will be reimbursed for all direct costs expended on behalf of
         the partnership.

6.       PURCHASE COMMITMENT

         Subject to certain conditions, investor partners may present their
         interests after five years from the partnership's first cash
         distribution from operations for purchase by the Managing General
         Partner. The Managing General Partner is not obligated to purchase more
         than 5% of the units in any calendar year. In the event that the
         Managing General Partner is unable to obtain the necessary funds, the
         Managing General Partner may suspend its purchase obligation.

7.       SUBORDINATION OF PORTION OF MANAGING GENERAL PARTNER'S NET PRODUCER
         REVENUE SHARE

         The Managing General Partner will subordinate up to 50% of its share of
         production revenues of the Partnership, net of related operating costs,
         direct costs, administrative costs, and all other costs not
         specifically allocated, to the receipt by the investor partners of cash
         distributions from the Partnership equal to at least 10% per unit,
         based on $10,000 per unit regardless of the actual price paid,
         determined on a cumulative basis, in each of the first five 12-month
         periods beginning with the Partnership's first cash distribution from
         operations.

8.       INDEMNIFICATION

         In order to limit the potential liability of the investor general
         partners for partnership liabilities and obligations, Atlas Resources
         has agreed to indemnify each investor general partner from any
         liability incurred which exceeds such partner's share of undistributed
         Partnership net assets and insurance proceeds.

9.       SUBSEQUENT EVENTS

         Atlas America, Inc. recently announced that it intends to form either a
         wholly-owned limited liability company or limited partnership
         subsidiary and transfer to that entity substantially all of its natural
         gas and oil exploration and production assets. In connection with that
         contemplated transaction, in March 2006 Atlas Resources, Inc. was
         merged into a newly-formed limited liability company, Atlas Resources,
         LLC, which is anticipated to become an indirect subsidiary of Atlas
         America's newly-formed subsidiary. Atlas Resources, LLC, however, will
         continue to serve as the Partnership's managing general partner, and
         does not expect that any of these transactions will have a material
         effect on the Partnership's financial position or results of
         operations. Atlas America, Inc. further intends to make a registered
         initial public offering of an estimated 20% minority interest in its
         newly-formed subsidiary.

             REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM




Board of Directors
ATLAS RESOURCES, INC.

We have audited the accompanying consolidated balance sheets of ATLAS RESOURCES,
INC. (a Pennsylvania corporation) and subsidiaries as of September 30, 2005 and
2004, and the related consolidated statements of income, changes in
stockholder's equity, and cash flows for the years then ended. These financial
statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.

We conducted our audits in accordance with the standards of the Public Company
Accounting Oversight Board (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. The Company is not required to
have, nor were we engaged to perform an audit of its internal control over
financial reporting. Our audit included consideration of internal control over
financial reporting as a basis for designing audit procedures that are
appropriate in the circumstances, but not for the purpose of expressing an
opinion on the effectiveness of the Company's internal control over financial
reporting. Accordingly, we express no such opinion. An audit also 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 consolidated financial position of ATLAS RESOURCES,
INC. and subsidiaries as of September 30, 2005 and 2004, and the consolidated
results of their operations and cash flows for the years then ended, in
conformity with accounting principles generally accepted in the United States of
America.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                               SEPTEMBER 30, 2005

NOTE 1 - NATURE OF OPERATIONS

         Atlas Resources, Inc. (the "Company"), a Pennsylvania corporation, and
its subsidiary, ARD Investments, are engaged in the exploration for development
and production of natural gas and oil primarily in the Appalachian Basin Area.
In addition, the Company performs contract drilling and well operation services.

         The Company is a second-tier wholly-owned subsidiary of Atlas America,
Inc. ("Atlas"), a publicly traded company trading under the symbol ATLS on the
NASDAQ System. The Company's operations are dependent upon the resources and
services provided by Atlas. The Company finances a substantial portion of its
drilling activities through drilling partnerships it sponsors and typically acts
as the managing general partner of and has a material interest in these
partnerships.

SPIN-OFF OF ATLAS FROM RESOURCE AMERICA, INC.

         On June 30, 2005, Resource America, Inc. ("RAI") the Company's former
indirect Parent, distributed its remaining 10.7 million shares of Atlas to its
stockholders in the form of a tax-free dividend. Although the distribution
itself is tax-free to RAI stockholders, as a result of the deconsolidation there
may be some tax liability arising from prior unrelated corporate transactions
among Atlas and some of its subsidiaries. Atlas (and the Company) no longer
consolidates with RAI as of June 30, 2005. The Company does not anticipate that
there will be a direct material impact on its financial position or results of
operations.

NOTE 2 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

PRINCIPLES OF CONSOLIDATION

         The consolidated financial statements include the accounts of the
Company and its wholly owned subsidiary. The Company also owns individual
interests in the assets, and is separately liable for its share of the
liabilities of energy partnerships, whose activities include only exploration
and production activities. In accordance with established practice in the oil
and gas industry, the Company includes in its consolidated financial statements
its pro-rata share of assets, liabilities, income and costs and expenses of the
energy partnerships in which it has an interest. All material intercompany
transactions have been eliminated.

USE OF ESTIMATES

         Preparation of the consolidated financial statements in conformity with
accounting principles generally accepted in the United States of America
requires management to make estimates and assumptions that affect the reported
amounts of assets and liabilities and the disclosure of contingent assets and
liabilities as of the date of the consolidated financial statements and the
reported amounts of revenues and costs and expenses during the reporting period.
Actual results could differ from these estimates.

NOTE 2 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

RECLASSIFICATIONS

         Certain reclassifications have been made to the fiscal 2004
consolidated financial statements to conform to the fiscal 2005 presentation.

COMPREHENSIVE INCOME

         Comprehensive income includes net income and all other changes in the
equity of a business during a period from transactions and other events and
circumstances from non-owner sources. There are no elements of comprehensive
income, other than net income, to report.

RECEIVABLES

         In evaluating its allowance for possible losses, the Company performs
ongoing credit evaluations of its customers and adjusts credit limits based upon
payment history and the customers' current creditworthiness, as determined by
the Company's review of its customers' credit information. The Company extends
credit on an unsecured basis to many of its energy customers. At September 30,
2005 and 2004, the Company's credit evaluation indicated that it has no need for
an allowance for possible losses.

PROPERTY AND EQUIPMENT

         Property and equipment is stated at cost. Depreciation, depletion and
amortization is based on cost less estimated salvage value primarily using the
unit-of-production or straight line method over the assets' estimated useful
lives. Maintenance and repairs are expensed as incurred. Major renewals and
improvements that extend the useful lives of property are capitalized.

        The estimated service lives of property and equipment are as follows:

  Pipelines, processing and compression facilities......         15-35 years
  Rights-of-way - Mid-Continent.........................            40 years
  Rights-of-way - Appalachia............................            20 years
  Land, building and improvements.......................         10-40 years
  Furniture and equipment...............................           3-7 years
  Other.................................................          3-10 years

OIL AND GAS PROPERTIES

         The Company follows the successful efforts method of accounting for oil
and gas producing activities. Exploratory drilling costs are capitalized pending
determination of whether a well is successful. Exploratory wells subsequently
determined to be dry holes are charged to expense. Costs resulting in
exploratory discoveries and all development costs, whether successful or not,
are capitalized. Geological and geophysical costs, delay rentals and
unsuccessful exploratory wells are expensed. Oil is converted to gas equivalent
basis ("mcfe") at the rate one-barrel equals 6 mcf. Depletion is provided on the
units-of-production method. Unproved properties are reviewed for impairment
annually, or whenever events or circumstances indicate that the carrying amount
of an asset may not be recoverable. An impairment charge would be recognized if
conditions indicated that the Company would not explore the acreage prior to
expiration of applicable leases or if the carrying value of the property
exceeded its fair value.

         The Company's long-lived assets are reviewed for impairment annually
for events or changes in circumstances that indicate that the carrying amount of
an asset may not be recoverable. Long-lived assets are reviewed for potential
impairment at the lowest levels for which there are identifiable cash flows that
are largely independent of other groups of assets. The review is done by
determining if the historical cost of proved properties less the applicable
accumulated depreciation, depletion and amortization and reserve for abandonment
is less than the estimated expected undiscounted future cash flows. The expected
future cash flows are estimated based on the Company's plans to continue to
produce and develop proved reserves. The expected future cash flows from the
sale of the production of reserves is calculated using estimated future prices
based upon market related information available to the Company, which includes

published futures prices. The estimated future level of production is based on
assumptions surrounding future levels of prices and costs, field decline rates,
market demand and supply, and the economic and regulatory climates. If the
carrying value exceeds such cash flows, an impairment loss is recognized for the
difference between the estimated fair market value (as determined by discounted
future cash flows), and the carrying value of the assets.

         Upon the sale or retirement of a complete unit of a proved property,
its cost is eliminated from the property accounts, and the resultant gain or
loss is reclassified to accumulated depletion. Upon the sale of an entire
interest in an unproved property that has been assessed for impairment
individually, a gain or loss is recognized in the statement of operations. If a
partial interest in an unproved property is sold, any funds received reduce the
cost in the interest retained.

ASSET RETIREMENT OBLIGATION

         If a reasonable estimate of the fair values of asset retirement
obligations can be made, such obligations are recorded when assets are acquired.
Changes to the estimated fair values of the assets are recorded in the period in
which they occur. Asset retirement obligations primarily relate to the
abandonment of oil and gas producing facilities and include costs to dismantle
and relocate or dispose of production equipment, gathering systems, wells and
related structures. Estimates, which are based on historical experience in
plugging and abandoning wells, include estimated remaining lives of the wells
based on reserve estimates, external estimates as to the cost to plug and
abandon the wells in the future and federal and state regulatory requirements.
The Company does not provide for a market risk premium associated with asset
retirement obligations because a reliable estimate cannot be determined.

FAIR VALUE OF FINANCIAL INSTRUMENTS

         The Company uses the following methods and assumptions in estimating
the fair value of each class of financial instruments for which it is
practicable to estimate fair value.

         For cash and cash equivalents, receivables and payables, the carrying
amounts approximate fair value because of the short maturity of these
instruments.

         For long-term debt, the carrying value approximates fair value because
interest rates approximate current market rates.

CONCENTRATION OF CREDIT RISK

         Financial instruments that potentially subject the Company to
concentrations of credit risk consist principally of periodic temporary
investments of cash. The Company places its temporary cash investments in
high-quality short-term money market instruments and deposits with high-quality
financial institutions and brokerage firms. At September 30, 2005, the Company
had $2,925,900 in deposits at various banks, of which $2,825,900 is over the
insurance limit of the Federal Deposit Insurance Corporation. No losses have
been experienced on such investments.

ENVIRONMENTAL MATTERS

         The Company is subject to various federal, state and local laws and
regulations relating to the protection of the environment. The Company has
established procedures for the ongoing evaluation of its operations to identify
potential environmental exposures and to comply with regulatory policies and
procedures.

         The Company accounts for environmental contingencies in accordance with
SFAS No. 5 "Accounting for Contingencies." Environmental expenditures that
relate to current operations are expensed or capitalized as appropriate.
Expenditures that relate to an existing condition caused by past operations, and
do not contribute to current or future revenue generation, are expensed.
Liabilities are recorded when environmental assessments and/or clean-ups are
probable, and the costs can be reasonably estimated. The Company maintains
insurance that may cover in whole or in part certain environmental expenditures.
For the two years ended September 30, 2005 and 2004, the Company had no
environmental matters requiring specific disclosure or the recording of a
liability.

REVENUE RECOGNITION

         The Company conducts certain energy activities through, and a portion
of its revenues is attributable to, sponsored energy limited partnerships. These
energy partnerships raise capital from investors to drill gas and oil wells. The
income from the Company's general partner interest is recorded when the gas and
oil are sold by a partnership.

         The Company contracts with the energy partnerships to drill partnership
wells. The contracts require that the energy partnerships must pay the Company
the full contract price upon execution. The income from a drilling contract is
recognized as the services are performed using the percentage of completion
method. The contracts are typically completed in less than 60 days. The Company
classifies the difference between the contract payments it has received and the
revenue earned as a current liability, included in liabilities associated with
drilling contracts.

         The Company recognizes transportation revenues at the time the natural
gas is delivered to the purchaser.

         The Company recognizes well services revenues at the time the services
are performed.

         The Company is entitled to receive well operating and management fees
according to the respective partnership agreements. The Company recognizes well
operating and management fees as income when earned and includes them in well
services revenues.

INCOME TAXES

         The Company is included in the consolidated federal income tax return
of its Parent. Income taxes are reported by the Company in amounts consistent
with what the Company's estimated taxes would have been had it filed a return on
a separate company basis utilizing its calculated effective rate of 23% and 18%
for fiscal years 2005 and 2004 respectively. The Company's effective tax rate is
lower than the federal statutory rate due to the benefit of percentage
depletion. Deferred tax assets and liabilities, which have been transferred to
the Parent since it files the consolidated tax return, are included in Advances
and note from Parent. These deferred taxes reflect the tax effect of temporary
differences between the tax bases of the Company's assets and liabilities and
the amounts reported in the financial statements. Separate company state tax
returns are filed in those states in which the Company is registered to do
business.

RECENTLY ISSUED FINANCIAL ACCOUNTING STANDARDS

         In May 2005, the Financial Accounting Standards Board, ("FASB") issued
Statement No.154, Accounting Changes and Error Corrections ("SFAS 154"). SFAS
154 requires retrospective application to prior periods' financial statements of
changes in accounting principle. It also requires that the new accounting
principle be applied to the balances of assets and liabilities as of the
beginning of the earliest period for which retrospective application is
practicable and that a corresponding adjustment be made to the opening balance
of retained earnings for that period rather than being reported in an income
statement. The statement will be effective for accounting changes and
corrections of errors made in fiscal years beginning after December 15, 2005.
The impact of SFAS 154 will depend on the nature and extent of any voluntary
accounting changes and correction of errors after the effective date, but
management does not currently expect SFAS 154 to have a material impact on the
Company's financial position or results of operations.

NOTE 2 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

RECENTLY ISSUED FINANCIAL ACCOUNTING STANDARDS (CONTINUED)

         In March 2005, the FASB issued FASB Interpretation No. 47, Accounting
for Conditional Asset Retirement Obligations ("FIN 47"), which will result in
(a) more consistent recognition of liabilities relating to asset retirement
obligations, (b) more information about expected future cash outflows associated
with those obligations, and (c) more information about investments in long-lived
assets because additional asset retirement cost will be recognized as part of
the carrying amounts of the assets. FIN 47 clarifies that the term conditional
asset retirement obligation as used in SFAS No. 143, Accounting for Asset
Retirement Obligations, refers to a legal obligation to perform an asset
retirement activity in which the timing and (or) method of settlement are
conditional on a future event that may or may not be within the control of the
entity. The obligation to perform the asset retirement activity is unconditional
even though uncertainty exists about the timing and (or) method of settlement.
Uncertainty about the timing and (or) method of settlement of a conditional
asset retirement obligation should be factored into the measurement of the
liability when sufficient information exists. FIN 47 also clarifies when an
entity would have sufficient information to reasonably estimate the fair value
of an asset retirement obligation. FIN 47 is effective no later than the end of
fiscal years ending after December 15, 2005. Retrospective application of
interim financial information is permitted, but not required. Early adoption of
this interpretation is encouraged. Management does not believe the
interpretation will have a significant impact on the Company's financial
position or results of operations.

         In December 2004, the FASB issued FASB Staff Position No. FSP 109-1
("FSP 109-1"), Application of FASB Statement No. 109, Accounting for Income
Taxes, to the Tax Deduction on Qualified Production Activities Provided by the
American Jobs Creation Act of 2004 ("AJCA"). The AJCA introduces a special 9%
tax deduction on qualified production activities. FSP 109-1 concludes that this
deduction should be accounted for as a special tax deduction in accordance with
SFAS No. 109. As such, the special deduction has no effect on deferred tax
assets and liabilities existing at the enactment date. Rather, the impact of
this deduction will be reported in the same period in which the deduction is
claimed in the Company's tax return. FSP 109-1 is not expected to have a
material impact on the Company's financial position or results of operations.

NOTE 3 -- OTHER ASSETS, INTANGIBLE ASSETS AND GOODWILL

INTANGIBLE ASSETS

         Intangible assets consist of partnership management and operating
contracts acquired through acquisitions and recorded at fair value on their
acquisition dates. The Company amortizes contracts acquired on a declining
balance method, over their respective estimated lives, ranging from five to
thirteen years. Amortization expense for the years ended September 30, 2005 and
2004 was approximately $478,000. The estimated amortization expense for each of
the next five fiscal years is approximately $478,000.

GOODWILL

         The Company applies the provisions of SFAS No. 142 ("SFAS 142")
Goodwill and Other Intangible Assets, which requires that goodwill no longer be
amortized, but instead evaluated for impairment at least annually. The
evaluation of impairment under SFAS 142 requires the use of projections,
estimates and assumptions as to the future performance of the Company's
operations, including anticipated future revenues, expected future operating
costs and the discount factor used. Actual results could differ from
projections, resulting in revisions to the Company's assumptions and, if
required, recognition of an impairment loss. The Company evaluated goodwill and
determined that there was no impairment at September 30, 2005. The Company will
continue to evaluate its goodwill at least annually and will reflect the
impairment of goodwill, if any, within the consolidated statements of income in
the period in which such impairment is indicated.

NOTE 4 - ASSET RETIREMENT OBLIGATION

         Effective October 1, 2002, the Company adopted the SFAS No. 143,
Accounting for Asset Retirement Obligations ("SFAS 143") which requires the
Company to recognize an estimated liability for the plugging and abandonment of
its oil and gas wells and associated pipelines and equipment. Under SFAS 143,
the Company must currently recognize a liability for future asset retirement
obligations if a reasonable estimate of the fair value of that liability can be
made. The associated asset retirement costs are capitalized as part of the
carrying amount of the long lived asset. SFAS 143 requires the Company to
consider estimated salvage value in the calculation of depreciation, depletion
and amortization. Consistent with industry practice, historically the Company
had determined the cost of plugging and abandonment on its oil and gas
properties would be offset by salvage values received. The adoption of SFAS 143
resulted in (i) an increase of total liabilities because retirement obligations
are required to be recognized, (ii) an increase in the recognized cost of assets
because the retirement costs are added to the carrying amount of the long-lived
assets and (iii) a decrease in depletion expense, because the estimated salvage
values are now considered in the depletion calculation.

         The Company determines the estimated liability based upon its
historical experience in plugging and abandoning wells. The estimate includes
consideration of the remaining lives of the wells based on reserve estimates,
external estimates as to the cost to plug and abandon the wells in the future
and federal and state regulatory requirements. The liability is discounted using
an assumed credit-adjusted risk-free interest rate. Revisions to the liability
could occur due to changes in estimates of plugging and abandonment costs or
remaining lives of the wells, or if federal or state regulators enact new
plugging and abandonment requirements. The increase in asset retirement
obligations in fiscal 2005 was due to an upward revision in the estimated cost
of plugging and abandoning wells.

         The Company has no assets legally restricted for purposes of settling
asset retirement obligations. The Company has determined that there are no
material retirement obligations associated with tangible long-lived assets.

         A reconciliation of the Company's liability for well plugging and
abandonment costs for the years ended September 30, 2005 and 2004 is as follows

Parent was reclassified to contributed capital. Interest expense related to the
note was $1.6 million and $2.1 million for the years ended September 30, 2005
and 2004. The advances have no repayment terms, therefore, the Company has
classified the amounts due the Parent as a current liability on its Consolidated
Balance Sheets.

         The Company is dependent on its Parent for management and
administrative functions and financing for its capital expenditures. The Company
paid management fees to its Parent of $47.3 million and $23.7 million for the
years ended September 30, 2005 and 2004, respectively.

NOTE 6 - DEBT

         During the fiscal year ended September 30, 2003, the Company entered
into two loans through General Motors Acceptance Corporation to finance the
purchase of ten trucks used in its well drilling and oil and gas production
activities. One loan had a principal balance at September 30, 2005 and 2004 of
$41,000 and $69,300, respectively, and bears interest at an annual rate of 1.9%.
The second loan had a principal balance at September 30, 2005 and 2004 of
$40,000 and $69,000, respectively, and bears interest at an annual rate of 2.9%.
The current portion of the long-term debt for the periods ended September 30,
2005 and 2004 were $59,000 and $56,000, respectively. Both loans had an original
term of 48 months.

NOTE 7 - COMMITMENTS AND CONTINGENCIES

         The Company is the managing general partner of various energy
partnerships, and has agreed to indemnify each investor partner from any
liability that exceeds such partner's share of partnership assets. Subject to
certain conditions, investor partners in certain energy partnerships have the
right to present their interests for purchase by the Company, as managing
general partner. The Company is not obligated to purchase more than 5% to 10% of
the units in any calendar year. Based on past experience, the Company believes
that any liability incurred would not be material.

         The Company may be required to subordinate a part of its net
partnership revenues to the receipt by investor partners of cash distributions
from the energy partnerships equal to at least 10% of their agreed subscriptions
determined on a cumulative basis, in accordance with the terms of the
partnership agreements.

         The Parent may draw from its revolving credit facility on behalf of the
Company. In March 2004, the Company's parent entered into a credit facility led
by Wachovia Bank, which has a current borrowing base of $75.0 million. The
facility permits draws based on the remaining proved developed non-producing and
proved undeveloped natural gas and oil reserves attributable to the Parent's
wells and the projected fees and revenues from operation of the wells and the
administration of the energy partnerships. Up to $50.0 million of the facility
may be in the form of standby letters of credit. The facility is secured by the
Parent's assets, including those of the Company.

      The revolving credit facility has a term ending in March 2007, when all
outstanding borrowings must be repaid. Borrowings bear interest at one of two
rates (elected at the borrower's option) which increase as the amount
outstanding under the facility increases: (i) Wachovia prime rate plus between
25 to 75 basis points, or (ii) LIBOR plus between 175 and 225 basis points. At
September 30, 2005 and 2004, the parent had $9.5 million and $26.7 million,
respectively, outstanding under this facility, including $1.5 million and $1.7
million at September 30, 2005 and 2004 under letters of credit. The interest
rates ranged from 5.52% to 7.0% at September 30, 2005.

NOTE 7 - COMMITMENTS AND CONTINGENCIES (CONTINUED)

         The Company is a party to various routine legal proceedings arising out
of the ordinary course of its business. Management believes that none of these
actions, individually or in the aggregate, will have a material adverse effect
on the Company's financial position or results of operations.

NOTE 8 - MAJOR CUSTOMERS

         The Company's natural gas is sold under contract to various purchasers.
For the year ended September 30, 2005, gas sales to Amerada Hess Corporation
(formerly First Energy Solutions Corporation) and UGI Energy Services accounted
for 52% and 30%, respectively, of total revenues. For the year ended September
30, 2004, First Energy Solutions Corporation accounted for 10% of total
revenues. No other customer accounted for 10% or more of total revenues for the
years ended September 30, 2005 and 2004.

         The development costs above for the years ended September 30, 2005 and
2004 were substantially all incurred for the development of proved undeveloped
properties.

         Oil and Gas Reserve Information (Unaudited) The estimates of the
Company's proved and unproved gas reserves are based upon evaluations made by
management and verified by Wright & Company, Inc., an independent petroleum
engineering firm, as of September 30, 2005 and 2004. All reserves are located
within the United States. 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 provisions for price
and cost escalation except by contractual arrangements.

         Proved oil and gas reserves are 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 only by contractual arrangements, but not on
escalations based upon future conditions.

         o        Reservoirs are considered proved if economic feasibility is
                  supported by either actual production or conclusive formation
                  tests. The area of a reservoir considered proved includes (a)
                  that portion delineated by drilling and defined by gas-oil
                  and/or oil-water contacts, if any; and (b) 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.

NOTE 9 - SUPPLEMENTAL OIL AND GAS INFORMATION (CONTINUED)

         o        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.
         o        Estimates of proved reserves do not include the following: (a)
                  oil that may become available from known reservoirs but is
                  classified separately as "indicated additional reservoirs";
                  (b) 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; (c) crude oil, natural gas and natural gas
                  liquids, that may occur in undrilled prospects; and (d) crude
                  oil and natural gas, and natural gas liquids, that may be
                  recovered from oil shale's, coal, gilsonite and other such
                  sources.

         Proved developed oil and gas reserves are reserves that can be expected
to be recovered through existing wells with existing equipment and operation
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.

         There are numerous uncertainties inherent in estimating quantities of
proven 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
measure 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 effects
have not been proved.

         The following schedule presents the standardized measure of estimated
discounted future net cash flows relating to proved oil and gas reserves. The
estimated future production is priced at fiscal year-end prices, adjusted only
for fixed and determinable increases in natural gas and oil prices provided by
contractual agreements. The resulting estimated future cash inflows are reduced
by estimated future costs to develop and produce the proved reserves based on
fiscal year-end cost levels. The future net cash flows are reduced to present
value amounts by applying a 10% discount factor. The standardized measure of
future cash flows was prepared using the prevailing economic conditions existing
at September 30, 2005 and 2004 and such conditions continually change.

NOTE 10 - SUBSEQUENT EVENTS

         Atlas recently announced that it intends to form either a wholly-owned
limited liability company or limited partnership subsidiary and transfer to that
entity substantially all of its natural gas and oil exploration and production
assets. In connection with that contemplated transaction, in March 2006 the
Company was merged into a newly-formed limited liability company, Atlas
Resources, LLC, which is anticipated to become an indirect subsidiary of Atlas'
newly-formed subsidiary. Atlas Resources, LLC, however, will continue to serve
as managing general partner of its various energy partnerships, and does not
expect that any of these transactions will have a material effect on the
Partnerships' financial position or results of operations. Atlas further intends
to make a registered initial public offering of an estimated 20% minority
interest in its newly-formed subsidiary.

NOTE 1 - MANAGEMENTS OPINION REGARDING INTERIM FINANCIAL STATEMENTS

         The consolidated financial statements of Atlas Resources, Inc. and its
wholly-owned subsidiary (the "Company") as of December 31, 2005 are unaudited.
Atlas Resources, Inc. is a wholly-owned subsidiary of Atlas America, Inc. (the
"Parent" or "Atlas"). These consolidated financial statements have been prepared
in accordance with accounting principles generally accepted in the United States
of America ("US GAAP") for interim financial information and certain rules and
regulations of the Securities and Exchange Commission. Accordingly, they do not
include all of the information and footnotes required by US GAAP for complete
financial statements.

         The consolidated financial statements and the information and tables
contained in the notes to the consolidated financial statements as of December
31, 2005 and for the three months ended December 31, 2005 and 2004 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 these
statements 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 results of operations for the three months
ended December 31, 2005 may not necessarily be indicative of the results of
operations for the full fiscal year ending September 30, 2006. Certain
reclassifications have been made to the consolidated financial statements as of
September 30, 2005 and for the three months ended December 31, 2004 to conform
to the presentation as of and for the three months ended December 31, 2005.

SPIN-OFF OF ATLAS FROM RESOURCE AMERICA, INC.

         On June 30, 2005, Resource America, Inc. ("RAI") the Company's former
indirect Parent, distributed its remaining 10.7 million shares of Atlas to its
stockholders in the form of a tax-free dividend. Although the distribution
itself is tax-free to RAI stockholders, as a result of the deconsolidation there
may be some tax liability arising from prior unrelated corporate transactions
among Atlas and some of its subsidiaries. The Company does not anticipate that
there will be a direct material impact on its financial position or results of
operations. Atlas (and the Company) no longer consolidates with RAI as of June
30, 2005.

NOTE 2 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

COMPREHENSIVE INCOME

         Comprehensive income (loss) includes net income (loss) and all other
changes in the equity of a business during a period from transactions and other
events and circumstances from non-owner sources. These changes other than net
income (loss), are referred to as "other comprehensive income (loss)" and for
the Company only include changes in the fair value, net of taxes, of unrealized
hedging gains and losses. For the three months ended December 31, 2005, the
Company had no realized gains or losses due to changes in the fair value of
hedges.

RECEIVABLES

         In evaluating its allowance for possible losses, the Company performs
ongoing credit evaluations of its customers and adjusts credit limits based upon
payment history and the customers' current creditworthiness, as determined by
the Company's review of its customers' credit information. The Company extends
credit on an unsecured basis to many of its energy customers. At December 31,
2005 and 2004, the Company's credit evaluation indicated that it has no need for
an allowance for possible losses.

NOTE 2 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

REVENUE RECOGNITION

         Because there are timing differences between the delivery of natural
gas, natural gas liquids ("NGL's") and oil and the Company's receipt of a
delivery statement, the Company has unbilled revenues. These revenues are
accrued based upon volumetric data from the Company's records and the Company's
estimates of the related transportation and compression fees, which are, in
turn, based upon applicable product prices. The Company had unbilled trade
receivables at December 31, 2005 and September 30, 2005 of $9.9 million and $8.6
million respectively, which are included in Accounts Receivable, on its
Consolidated Balance Sheets.

SUPPLEMENTAL CASH FLOW INFORMATION

         The Company considers temporary investments with maturity at the date
of acquisition of 90 days or less to be cash equivalents.

RECENTLY ISSUED FINANCIAL ACCOUNTING STANDARDS

         In May 2005, the Financial Accounting Standards Board, ("FASB") issued
Statement No.154, Accounting Changes and Error Corrections ("SFAS 154"). SFAS
154 requires retrospective application to prior periods' financial statements of
changes in accounting principle. It also requires that the new accounting
principle be applied to the balances of assets and liabilities as of the
beginning of the earliest period for which retrospective application is
practicable and that a corresponding adjustment be made to the opening balance
of retained earnings for that period rather than being reported in an income
statement. The statement will be effective for accounting changes and
corrections of errors made in fiscal years beginning after December 15, 2005.
The impact of SFAS 154 will depend on the nature and extent of any voluntary
accounting changes and correction of errors after the effective date, but
management does not currently expect SFAS 154 to have a material impact on the
Company's financial position or results of operations.

         In March 2005, the FASB issued FASB Interpretation No. 47, Accounting
for Conditional Asset Retirement Obligations ("FIN 47"), which will result in
(a) more consistent recognition of liabilities relating to asset retirement
obligations, (b) more information about expected future cash outflows associated
with those obligations, and (c) more information about investments in long-lived
assets because additional asset retirement cost will be recognized as part of
the carrying amounts of the assets. FIN 47 clarifies that the term conditional
asset retirement obligation as used in SFAS No. 143, Accounting for Asset
Retirement Obligations, refers to a legal obligation to perform an asset
retirement activity in which the timing and (or) method of settlement are
conditional on a future event that may or may not be within the control of the
entity. The obligation to perform the asset retirement activity is unconditional
even though uncertainty exists about the timing and (or) method of settlement.
Uncertainty about the timing and (or) method of settlement of a conditional
asset retirement obligation should be factored into the measurement of the
liability when sufficient information exists.

         FIN 47 also clarifies when an entity would have sufficient information
to reasonably estimate the fair value of an asset retirement obligation. FIN 47
is effective no later than the end of fiscal years ending after December 15,
2005. Retrospective application of interim financial information is permitted,
but is not required. Early adoption of this interpretation is encouraged.
Management does not believe the interpretation will have a significant impact on
the Company's financial position or results of operations.

NOTE 2 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

         In December 2004, the FASB issued FASB Staff Position No. FSP 109-1
("FSP 109-1"), Application of FASB Statement No. 109, Accounting for Income
Taxes, to the Tax Deduction on Qualified Production Activities Provided by the
American Jobs Creation Act of 2004 ("AJCA"). The AJCA introduces a special 9%
tax deduction on qualified production activities. FSP 109-1 concludes that this
deduction should be accounted for as a special tax deduction in accordance with
SFAS No. 109. As such, the special deduction has no effect on deferred tax
assets and liabilities existing at the enactment date. Rather, the impact of
this deduction will be reported in the same period in which the deduction is
claimed in the Company's tax return. FSP 109-1 is not expected to have a
material impact on the Company's financial position or results of operations.

NOTE 4 - COMMITMENTS AND CONTINGENCIES

         The Company is the managing general partner of various energy
partnerships, and has agreed to indemnify each investor partner from any
liability that exceeds such partner's share of partnership assets. Subject to
certain conditions, investor partners in certain energy partnerships have the
right to present their interests for purchase by the Company, as managing
general partner. The Company is not obligated to purchase more than 5% to 10% of
the units in any calendar year. Based on past experience, the Company believes
that any liability incurred would not be material.

         The Company may be required to subordinate a part of its net
partnership revenues to the receipt by investor partners of cash distributions
from the energy partnerships equal to at least 10% of their agreed subscriptions
determined on a cumulative basis, in accordance with the terms of the
partnership agreements.

         The Parent may draw from its revolving credit facility on behalf of the
Company. In March 2004, the Company's parent entered into a credit facility led
by Wachovia Bank, which has a current borrowing base of $75.0 million. The
facility permits draws based on the remaining proved developed non-producing and
proved undeveloped natural gas and oil reserves attributable to the Parent's
wells and the projected fees and revenues from operation of the wells and the
administration of the energy partnerships. Up to $50.0 million of the facility
may be in the form of standby letters of credit. The facility is secured by the
Parent's assets, including those of the Company. The revolving credit facility
has a term ending in March 2007, when all outstanding borrowings must be repaid,
and bears interest at one of two rates (elected at the borrower's option) which
increases as the amount outstanding under the facility increases. At December
31, 2005, the Parent had no outstanding balance under this facility.

NOTE 4 - COMMITMENTS AND CONTINGENCIES (CONTINUED)

         The Company is a party to various routine legal proceedings arising out
of the ordinary course of its business. Management believes that none of these
actions, individually or in the aggregate, will have a material adverse effect
on the Company's financial position or results of operations.

NOTE 5 - DERIVATIVE INSTRUMENTS

         The Company from time to time enters into natural gas futures and
option contracts to hedge its 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 counterparties. NYMEX contracts are generally
settled with offsetting positions, but may be settled by the delivery of natural
gas.

         The Company formally documents all relationships between hedging
instruments and the items being hedged, including the Company's risk management
objectives and strategy for undertaking the hedging transactions. This includes
matching the natural gas futures and options contracts to the forecasted
transactions. The Company assesses, both at the inception of the hedge and on an
ongoing basis, whether the derivatives are highly effective in offsetting
changes in fair value of hedged items. Historically these contracts have
qualified and been designated as cash flow hedges and recorded at their fair
values. Gains or losses on future contracts are determined as the difference
between the contract price and a reference price, generally prices on NYMEX.
Such gains and losses are charged or credited to Accumulated Other Comprehensive
Income (Loss) and recognized as a component of sales revenue in the month the
hedged gas is sold. If it is determined that a derivative is not highly
effective as a hedge or it has ceased to be a highly effective hedge, due to the
loss of correlation between changes in gas reference prices under a hedging
instrument and actual gas prices, the Company will discontinue hedge accounting
for the derivative and subsequent changes in fair value for the derivative will
be recognized immediately into earnings.

         At December 31, 2005, the Company had 60 open natural gas futures
contracts related to natural gas sales covering 2,619,000 dekatherms ("Dth")
(net to the Company) of natural gas, maturing through December 31, 2009 at a
combined average settlement price of $9.24 per Dth. The Company has not
recognized any income or loss on settled contracts covering natural gas
production for the three months ended December 31, 2005 and 2004, respectively.
The Company recognized no gains or losses during the three months ended December
31, 2005 for hedge ineffectiveness or as a result of the discontinuance of cash
flow hedges.

         Derivatives are recorded on the balance sheet as assets or liabilities
at fair value. For derivatives qualifying as hedges, the effective portion of
changes in fair value are recognized in stockholders' equity as Accumulated
Other Comprehensive Income (Loss) and reclassified to earnings as such
transactions are settled. For non-qualifying derivatives and for the ineffective
portion of qualifying derivatives, changes in fair value are recognized in
earnings as they occur. At December 31, 2005, the Company reflected net hedging
liabilities on its balance sheet of $1.6 million. At September 30, 2005, the
Company had no hedging assets or liabilities. Ineffective hedge gains and losses
are recorded within the consolidated statements of income while the hedge
contract is open and may increase or decrease until settlement of the contract.

NOTE 6 - INCOME TAXES

         The Company is included in the consolidated federal income tax return
of its Parent. Income taxes are presented as if the Company had filed a return
on a separate company basis utilizing its calculated effective rate of 34% and
23% for fiscal years 2006 and 2005 respectively. The Company's effective tax
rate is lower than the federal statutory rate due to the benefit of percentage
depletion. Deferred taxes, which are included in Advances and note from Parent,
reflect the tax effect of temporary differences between the tax basis of the
Company's assets and liabilities and the amounts reported in the financial
statements. Separate company state tax returns are filed in those states in
which the Company is registered to do business.

NOTE 7 - SUBSEQUENT EVENTS

         Atlas recently announced that it intends to form either a wholly-owned
limited liability company or limited partnership subsidiary and transfer to that
entity substantially all of its natural gas and oil exploration and production
assets. In connection with that contemplated transaction, in March 2006 the
Company was merged into a newly-formed limited liability company, Atlas
Resources, LLC, which is anticipated to become an indirect subsidiary of Atlas'
newly-formed subsidiary. Atlas Resources, LLC, however, will continue to serve
as managing general partner of its various energy partnerships, and does not
expect that any of these transactions will have a material effect on the
Partnerships' financial position or results of operations. Atlas further intends
to make a registered initial public offering of an anticipated 20% minority
interest in its newly-formed subsidiary.

                          CURRENTLY PROPOSED PROSPECTS

                      ATLAS AMERICA PUBLIC #15-2006(B) L.P.






               INFORMATION REGARDING CURRENTLY PROPOSED PROSPECTS


The partnerships do not currently hold any interests in any prospects on which
the wells will be drilled, and the managing general partner has absolute
discretion in determining which prospects will be acquired to be drilled.
However, set forth below is information relating to certain proposed prospects
and the wells which will be drilled on the prospects by Atlas America Public
#15-2006(B) L.P., which is the second partnership in the program and must be
closed by December 31, 2006. It is referred to in this section as the "2006(B)
Partnership." One well will be drilled on each development prospect, and for
purposes of this discussion the well and prospect are referred to together as
the "well." The managing general partner does not anticipate that the wells will
be selected in the order in which they are set forth below. Also, the wells
currently proposed to be drilled by the 2006(B) Partnership when its
subscription proceeds are released from escrow, and from time to time
thereafter, are subject to the managing general partner's right to:


     o    withdraw the wells and to substitute other wells;

     o    take a lesser working interest in the wells;

     o    add other wells; or

     o    any combination of the foregoing.


The specified wells represent the necessary wells if approximately $34 million
is raised and the 2006(B) Partnership takes the working interest in the wells
which is set forth below in the "Lease Information" for each well. The managing
general partner has not proposed any other wells if:


     o    a greater amount of subscription proceeds is raised;

     o    a lesser working interest in the wells is acquired; or

     o    the wells are substituted for any of the reasons set forth below.


The managing general partner has not authorized any person to make any
representations to you concerning the possible inclusion of any other wells
which will be drilled by the 2006(B) Partnership or the other remaining
partnership, and you should rely only on the information in this prospectus. The
currently proposed wells will be assigned to the 2006(B) Partnership unless
there are circumstances which, in the managing general partner's opinion, lessen
the relative suitability of the wells. These considerations include:

     o    the amount of the subscription proceeds received by the 2006(B)
          Partnership;


     o    the latest geological and production data available;

     o    potential title or spacing problems;

     o    availability and price of drilling services, tubular goods and
          services;

     o    approvals by federal and state departments or agencies;

     o    agreements with other working interest owners in the wells;

                                        1


Any substituted and/or additional wells will meet the same general criteria that
the managing general partner used in selecting the currently proposed wells, and
generally will be located in areas where the managing general partner or its
affiliates have previously conducted drilling operations. You, however, will not
have the opportunity to evaluate for yourself the relevant production and
geological information for the substituted and/or additional wells.


The information regarding the currently proposed wells is intended to help you
evaluate the economic potential and risks of drilling the proposed wells. This
includes production information for wells in the same general area as the
proposed well, which the managing general partner believes is an important
indicator in evaluating the economic potential of any well to be drilled.
However, a well drilled by the 2006(B) Partnership may not experience production
comparable to the production experienced by wells in the surrounding area since
the geological conditions in these areas can change in a short distance. Also,
the managing general partner has not been able to obtain production information
for previously drilled wells in the immediate areas where a portion of the
currently proposed wells in Pennsylvania are situated because the information is
not available to the managing general partner as discussed in "Risk Factors -
Risks Related to an Investment In a Partnership - Lack of Production Information
Increases Your Risk and Decreases Your Ability to Evaluate the Feasibility of a
Partnership's Drilling Program." The managing general partner has proposed these
wells to be drilled, even though there is no production data for other wells in
the immediate area available to the managing general partner, because geologic
trends in the immediate area, such as sand thickness, porosities and water
saturations, lead the managing general partner to believe that the proposed
wells also will be productive.


When reviewing production information for each well offsetting or in the general
area of a proposed well to be drilled you should consider the factors set forth
below.

     o    The length of time that the well has been on-line, and the period for
          which production information is shown. Generally, the shorter the
          period for which production information is shown the less reliable
          this information is, when used for predicting the ultimate recovery of
          a well.

     o    Production from a well declines throughout the life of the well. The
          rate of decline, the "decline curve," varies based on which geological
          formation is producing, and may be affected by the operation of the
          well. For example, the wells in the Clinton/Medina geological
          formation will have a different decline curve from the wells in the
          Mississippian/Upper Devonian Sandstone Reservoir in Fayette and Greene
          Counties. Also, each well in a geological formation or reservoir will
          have a different rate of decline from the other wells in the same
          formation or reservoirs.

     o    The greatest volume of production ("flush production") from a well
          usually occurs in the early period of well operations and may indicate
          a greater reserve volume (generally, the ultimate amount of natural
          gas and oil recoverable from a well) than the well actually will
          produce. This period of flush production can vary depending on how the
          well is operated and the location of the well.

      o   The production information for the majority of the wells is incomplete
          or very limited. The designation "N/A" means:

[START]
          o    the production information was not available to the managing
               general partner for the reasons discussed in "Risk Factors -
               Risks Related to an Investment In a Partnership - Lack of
               Production Information Increases Your Risk and Decreases Your
               Ability to Evaluate the Feasibility of a Partnership's Drilling
               Program"; or

          o    if the managing general partner was the operator, then when the
               information was prepared the well was:

               o    not completed;

               o    completed, but not on-line to sell production; or

               o    producing for only a short period of time.

     o    Production information for wells located close to a proposed well
          tends to be more relevant than production information for wells
          located farther away, although performance and volume of production
          from wells located on contiguous prospects can be much different.

                                       2


     o    Consistency in production among wells tends to confirm the reliability
          and predictability of the production.

INVESTIGATION SUMMARY


OBJECTIVE

     The purpose of the following investigation is to evaluate the geologic
feasibility and further development of the Fayette Prospect Area as proposed by
Atlas Resources, Inc. ("Atlas").

AREA OF INVESTIGATION

     A portion of this prospect area, herein identified for drilling in ATLAS
AMERICA PUBLIC #15-2006(B) L.P., contains acreage in Luzerne, Redstone,
Menallen, Franklin, Springhill, Nicholson, German, Georges, Washington,
Jefferson and Perry Townships of Fayette County; Cumberland Township of Greene
County; and Rostraver Township of Westmoreland County; located in southwestern
Pennsylvania. Eighty (80) drilling prospects have currently been designated for
this program in the prospect area, which will be targeted to produce natural gas
from Mississippian and Upper Devonian reservoirs, found at depths from 1900 feet
to 5500 feet beneath the earth's surface. These will be the only prospects
evaluated for the purposes of this report.

METHODOLOGY

     Atlas provided the data incorporated into this report. Geological mapping
and the interpretations by Atlas geologists were also examined. Available
"electric" log, completion and production data on "key" wells within and
adjacent to the defined prospect area were utilized to determine productive and
depositional trends

                              PROSPECT AREA HISTORY

DRILLING ACTIVITY

The proposed drilling area lies within a region of southwestern Pennsylvania,
which has been active for the past six years in terms of exploration for, and
exploitation of natural gas reserves. Development within and adjacent to the
Fayette Prospect Area has continued steadily since 1996. Over twelve hundred
(1200) wells have been drilled in the area during this period. Atlas has
encountered favorable drilling and production results while solidifying a strong
acreage position of nearly 90,000 acres, as Atlas continues to identify and
extend productive trends. Drilling is ongoing as of the date of this report with
recent wells displaying favorable initial drilling and completion results.

     The area of proposed drilling is situated in portions of Fayette and Greene
Counties that have had established production from shallower, historic pay
zones. Atlas will drill at least 1000 feet from producing wells, although Atlas
may drill a new well or re-enter an existing well closer than 1000 feet from
plugged and abandoned wells.

GEOLOGY

     STRATIGRAPHY, LITHOLOGY & DEPOSITION

     The Mississippian reservoirs currently producing in the Fayette Prospect
Area are the Burgoon Sandstone (lower Big Injun) and the 2nd Gas Sand. The
Burgoon Sandstone is part of the massive Big Injun fluvial-deltaic sand system,
which extends from eastern Kentucky through West Virginia into southwestern
Pennsylvania. This reservoir is an historic producing zone in this region, with
some wells still producing long beyond fifty years. There is not much history of
production from the 2nd Gas Sand in this area.

     The Upper Devonian reservoirs consist of three groups of sands, Upper
Venango, Lower Venango and Bradford. Each of these "Groups" has multiple
reservoirs making up their total rock section. The Upper Venango Group consists
of the Gantz Sand and the Fifty Foot Sand. The Lower Venango Group consists of
the Fifth Sand and the Bayard Sand. Depositional environments of these Upper and
Lower Venango Group sands are of near shore to offshore marine settings related
to the last major advance of the Catskill Delta. The Bradford Group consists of
the Lower Warren Sand, Upper Speechley Sand, Lower Speechley Sand, Upper
Balltown Sand and the First Bradford Sand. Depositional environments of these
sands are offshore marine, pro-delta and basin floor settings related to the
intermediate advance of the Catskill Delta.


                                       41



[GRAPHIC OMITTED]\
Stratigraphically, in descending order, the potentially productive units of the
Mississippian and Upper Devonian Groups are: Burgoon, 2nd Gas Sand, Gantz, Fifty
Foot, Fifth, Bayard, Lower Warren, Upper Speechley, Lower Speechley, Upper
Balltown, and First Bradford Sand. Stratigraphic relationships are illustrated
in the diagram.

|X| The BURGOON SANDSTONE is a fine to medium grained, medium to massively
bedded, light-gray sandstone ranging in thickness from 200-250 feet. Average
porosity values for this sand range from 6% to 12% regionally. It is not
uncommon to encounter porosities as high as 20% and attendant producible natural
open flows from this sand. Tracking these producible natural open flow trends is
targeted for further development. Also, this zone does produce water in certain
locales within the Fayette Prospect Area. This reservoir is considered a
secondary target in the natural open flow trend areas.

|X| The 2ND GAS SAND of this region has limited areal extent and therefore is
not discussed in the literature regarding lithology, thickness etc. It can be
inferred from underlying and overlying sands that it is probably a fine to very
fine grained, light gray sand. Subsurface mapping indicates that the sand can
achieve a thickness of twenty (20) feet. Average porosity values for this sand
range from 10% to 13% when this zone is present in the area. Peak porosities of
17% have been encountered within the prospect area. This reservoir is considered
to be a secondary target when encountered.

|X| The GANTZ SAND is a white to light-gray, medium to coarse-grained sandstone
ranging in thickness from a few feet to over sixty (60) feet. Average porosity
values for this sand range from 5% to 10% regionally. Within the area of
investigation, porosities in excess of 13% occur within localized trends
characterized by producible natural open flows. These trends are targeted for
future development. This reservoir is considered a primary target in the natural
open flow trend areas.

|X| The FIFTY FOOT SAND is a white to light gray, thinly bedded, fine-grained
sandstone ranging in thickness from ten (10) to thirty (30) feet. Average
porosity values for this sand range from 5% to 8% regionally. Within the
prospect area, porosities in excess of 12% occur within localized trends
targeted for future development. This sand reservoir is considered a secondary
target.

|X| The FIFTH SAND is a white to light gray, very fine to fine grained sandstone
ranging in thickness from a few feet to forty (40) feet. Within the main Fifth
fairway, porosity values average from 9% to 15%. This sand is considered a
primary target and will be exploited in future development.

|X| The BAYARD SAND in the prospect area ranges in thickness from a few feet to
more than sixty (60) feet. Average porosity values range from 5% to 12% for this
fine to coarse-grained sandstone. Discrete reservoirs within the sand have been
identified and mapped. Gas shows in the member sandstones delineate trends
within the prospect area and will be targeted for future development. This sand
is considered a primary target. |X| The LOWER WARREN SAND is a primary target in
the prospect area. Average thickness for this sand ranges from zero (0) feet to
over forty (40) feet. Porosities average between 8% and 12% in the area. Gas
shows are commonly found in this sand, which is probably a fine-grained,
well-sorted sand. This reservoir is targeted for future development.

|X| The UPPER SPEECHLEY SAND is considered a secondary target with average
thickness ranging from two (2) feet to ten (10) feet over much of the prospect
area. Gas shows from this sand are common throughout the area and the zone is
combined with other zones when treated.

                                       42


|X| The LOWER SPEECHLEY SAND is a primary target in the area with reservoir
thickness ranging from zero (0) to over forty (40) feet. Average porosity values
range from 5% to 12% where the sand is present. Significant natural and after
treatment flows from this sand have been encountered. This sand is being
targeted throughout the prospect area.

|X| The UPPER BALLTOWN SAND is currently being produced in a few wells in the
prospect area. The zone is a siltstone with fracture-enhanced porosity, based on
log interpretation, and has associated gas shows. This sand is considered a
secondary target and is usually combined with other zones when treated.

|X| The FIRST BRADFORD SAND, like the Balltown above, is currently being
produced in a few wells in the prospect area. This silty-sand does have porosity
up to 10% in the area and is considered to be a secondary target when
encountered.

     RESERVOIR CHARACTERISTICS

     Petroleum reservoirs are formed by the presence of an impermeable barrier
trapping commercial quantities of natural gas in a more permeable medium. In the
Mississippian and Upper Devonian reservoirs, this occurs either
stratigraphically when a permeable sand containing hydrocarbons encounters
impermeable shale or when permeable sand changes gradually into non-permeable
sand by a cementation process known as "diagenesis". Thus, this type of trap
represents cemented-in hydrocarbon accumulations.


     Electric well logs can be used in conjunction with production to interpret
reservoir parameters. When sandstones in the Mississippian and Upper Devonian
reservoirs develop porosity in excess of 8%, or a bulk density of 2.50 or less,
the permeability of the reservoir can become great enough to allow commercial
production of natural gas. Small, naturally occurring cracks in the formation,
referred to as micro-fractures, can also enhance permeability.

     A gamma, bulk density, neutron, induction and temperature log suite showing
sand development in both the Mississippian and Upper Devonian reservoirs is
illustrated.

     The temperature log shown in the illustration at left identifies where gas
is entering the wellbore. Evidence of a temperature "kick" or cooling is also an
indication of enhanced permeability and the willingness of the reservoir to
produce natural gas.

PRODUCTION

     The Fayette prospect area produces from a number of reservoirs of different
age and type. Each well has a unique combination of these reservoirs yielding
different production declines. While Atlas anticipates production from each
reservoir to be comparable to like reservoirs historically produced throughout
the Appalachian Basin, a model decline curve for this prospect area is not
included due to multiple sets of commingled reservoirs exclusively found in this
area.

                              INVESTIGATION SUMMARY


OBJECTIVE

     The purpose of the following investigation is to evaluate the geologic
feasibility and further development of the Crawford Prospect Area as proposed by
Atlas Resources, Inc. ("Atlas").

AREA OF INVESTIGATION

     A portion of this prospect area, herein identified for drilling in ATLAS
AMERICA PUBLIC #15-2006(B) L.P., contains acreage in Randolph and Richmond
Townships of Crawford County, located in northwestern Pennsylvania. Twenty-eight
(28) drilling prospects will be designated for this program and will be targeted
to produce natural gas from Clinton-Medina Group reservoirs, found at an average
depth range of approximately 5,000 to 6,300 feet beneath the earth's surface
over the prospect area. These will be the only prospects evaluated for the
purposes of this report.

METHODOLOGY

     The data incorporated into this report was provided by Atlas and the
in-house archives of UEDC, Inc. Geological mapping and the interpretations by
Atlas geologists were also examined. Available "electric" log, completion, and
production data on "key" wells within and adjacent to the defined prospect area
were utilized to determine productive and depositional trends.

                              PROSPECT AREA HISTORY

DRILLING ACTIVITY

     The proposed drilling area lies within a region of northwestern
Pennsylvania which has been very active for the past decade in terms of
exploration for, and exploitation of natural gas reserves. Development within
and adjacent to the Crawford Prospect Area has escalated since 1986, with Atlas
and its affiliates drilling over fourteen hundred (1400) wells during this
period. Atlas has encountered favorable drilling and production results while
solidifying a strong acreage position, and continues to identify and extend
productive trends. Drilling is ongoing as of the date of this report with recent
wells displaying favorable initial drilling and completion results. Competitive
activity has begun east of the prospect area, confirming the Clinton-Medina
Group of Lower Silurian age as a viable target for the further development of
producible quantities of natural gas.

     STRATIGRAPHY, LITHOLOGY & DEPOSITION

     Regionally, the Clinton-Medina Group was deposited in tide-dominated
shoreline, deltaic, and shelf environments and is lithologically comprised of
alternating sandstones, siltstones and shales. Productive sandstones are
composed of siliceous to dolomitic subarkoses, sublitharenites, and quartz
arenites. Reservoir quality sands occur throughout the delta-complex from
eastern Ohio through northwestern Pennsylvania and western New York. The
Clinton-Medina Group, deposited during the Lower Silurian, overlies the Upper
Ordovician age Queenston shale and is capped by the Middle Silurian Reynales
Formation. This dolomitic limestone "cap" is known locally to drillers as the
"Packer Shell".

     Stratigraphically, in descending order, the potentially productive units of
the Clinton-Medina Group consist of the: 1) Thorold, 2) Grimsby, 3) Cabot Head,
4) Whirlpool members. The diagram illustrates these stratigraphic relationships.

                                       54


     The WHIRLPOOL is a light gray quartzose sandstone to siltstone ranging in
thickness from five (5) to twenty (20) feet. Average porosity values for this
sand member range from five (5) to ten (10) percent regionally. Within the area
of investigation, porosities in excess of twelve (12) percent occur within
localized trends targeted for further development.

     The CABOT HEAD is a dark green to black shale, most likely of marine
origin. Within the investigated area the CABOT HEAD SANDSTONE has been
encountered in numerous wells. This formation has been found to contribute
natural gas when reservoir characteristics, including evidence of enhanced
permeability, warrant completion. This sand member is considered a secondary
target.

     The GRIMSBY is the thickest sandstone member of the Clinton-Medina Group.
Sand development ranges from ten (10) to forty-five (45) feet within an interval
comprised of fine to very fine, light gray to red sandstones and siltstones
broken up by thin dark gray silty shale layers. Average porosity values for the
Grimsby are approximately six (6) to (10) percent over the pay interval
regionally. Permeability may be enhanced locally by the presence of naturally
occurring micro-fractures. Future development focuses on established production
trends.

     The THOROLD sandstone is the uppermost producing interval of the
Clinton-Medina sequence. This interbedded ferric sand, silt and shale interval
averages forty (40) to seventy (70) feet, from west to east in the prospect
area. Where pay sand development occurs, porosities are in the typical
Clinton-Medina group range of six (6) to (10) percent. Permeability may be
enhanced locally by the presence of naturally occurring micro-fractures.

RESERVOIR CHARACTERISTICS

     Petroleum reservoirs are formed by the presence of an impermeable barrier
trapping natural gas of commercial quantities in a more permeable medium. In the
Clinton-Medina, this occurs either stratigraphically when a permeable sand
containing hydrocarbons encounters an impermeable shale or when a permeable sand
changes gradually into a non-permeable sand by a cementation process known as
"diagenesis". Thus, this type of trap represents cemented-in hydrocarbon
accumulations.

     Electric well logs can be used in conjunction with production to interpret
reservoir parameters. When sandstones in the Thorold, Grimsby, Cabot Head or
Whirlpool develop porosity in excess of 6%, or a bulk density of 2.55 or less,
the permeability of the reservoir (which ranges from <0.l to >0.2 mD) can become
great enough to allow commercial production of natural gas. Small, naturally
occurring cracks in the formation, referred to as micro-fractures, can also
enhance permeability. A gamma, bulk density, density porosity and neutron log
suite showing sand development in the Grimsby, Cabot Head and Whirlpool is
illustrated.

     Two other phenomena detected by well logs can occur which are indicators of
enhanced permeability. These indicators used to detect productive intervals are:

     o Mudcake buildup across the zone of interest - after loading the wellbore
with brine fluid and circulating, an interval with enhanced permeability will
accept fluid, filtering out the solids and leaving behind a buildup (or mudcake)
on the formation wall. This is detectable with a caliper log.

[GRAPHIC OMITTED]


                                       55


[GRAPHIC OMITTED]

     o Invasion profile - during circulation, a brine that has a high
conductivity (or low resistivity) that is accepted into the formation (as
described above) will change the electrical conductivity of the reservoir rock
near and around the wellbore. The resistivity will be low nearest to the
wellbore and will increase away from the wellbore. As shown in the example, a
dual laterolog can be used to detect this profile created by a permeable zone -
it records resistivity near the wellbore as well as deeper into the formation. A
zone with enhanced permeability will show a separation between the shallow and
deep laterologs, while a zone with little or no permeability would cause the two
resistivity measurements to read exactly the same.


PRODUCTION

     A model decline curve has been created based on the production histories
from approximately 900 wells drilled by Atlas and its programs in the adjacent
Mercer Fields. This model decline curve is consistent with the average estimated
decline curves for over 200 undeveloped well locations in the Mercer Field which
were used by Wright & Company, Inc., independent petroleum consultants, in
preparing Atlas' year 2000 reserve report. The model decline curve is
illustrated in the diagram below:


[GRAPHIC OMITTED]


     It is important to note that the model decline curve is intended only to
present how a well's production may decline from year to year, and does not
attempt to predict the average recoverable reserves per well.

     Also, the model decline curve is a forward-looking statement based on
certain assumptions and analyses of historical trends, current conditions and
expected future developments. The model decline curve is subject to a number of
risks and uncertainties including the risk that the wells are productive but do
not produce enough revenue to return the investment made and uncertainties
concerning the price of natural gas and oil. Actual results in this drilling
program will vary from the model decline curve, although a rapid decline in
production within the first several years can be expected.

(1)      Subject to maintenance of drilling commitments during the primary term
         thereof; each well drilled is earned and rights do not expire with the
         termination of rights to continue development.
(2)      Overriding royalty interests to Knox Energy, LLC are reduced when Knox
         chooses to participate in the development of a well. If Knox
         participates in a well for a 50% working interest, the well will be
         burdened by an overriding royalty of 1/64 or 1.5625%. If Knox
         participates in a well for less than 50% working interest, the
         overriding royalty to Knox will be determined by subtracting from an
         overriding royalty of 3.125% an amount determined by multiplying
         1.5625% by a fraction, the numerator of which is Knox's working
         interest and the denominator of which is 50%.







                                       61


(3)      Knox has the right to participate in any or all wells at an amount
         equal to or less than 50% working interest. Participation by Knox will
         cause an adjustment to the Net Revenue Intrest and the Working Interest
         available to the Partnership.
(4)      Forty acres are earned for each well.
(5)      Held by production, provided Lessee maintains its annual drilling
         commitment.
(6)      12.5% of the gross proceeds free of all costs and expenses whatsoever
         for all gas sold at the price of $3.00 per MMBtu. For all gross
         proceeds in excess of $3.00 per MMBtu, Heartwood will receive an
         additional royalty equal to 3% of the gross proceeds received by Lessee
         in excess of $3.00 per MMBtu. The payment for gas sold at a price of
         greater than $3.00 per MMBtu will affect the Net Revenue Interest
         computation.

                              INVESTIGATION SUMMARY



OBJECTIVE


     The purpose of the following investigation is to evaluate the geologic
feasibility and further development of the Tennessee Knox Energy Prospect Area
as proposed by Atlas Resources, Inc. ("Atlas").



AREA OF INVESTIGATION


     A portion of this prospect area contains acreage in Scott, Anderson and
Morgan Counties of Tennessee. Twenty-seven (27) drilling prospects within this
area in ATLAS AMERICA PUBLIC #15-2006(B) L.P. will be targeted to produce
natural gas from Mississippian and Devonian reservoirs, found at depths from
1500 feet to 5000 feet beneath the earth's surface. These will be the only
prospects evaluated for the purposes of this report.



METHODOLOGY


     Atlas and the in-house archives of UEDC, Inc. provided the data
incorporated into this report. Geological mapping and the interpretations by
Atlas geologists were also examined. Available "electric" log, completion and
production data on "key" wells within and adjacent to the defined prospect area
were used to determine productive and depositional trends.




                       TENNESSEE KNOX ENERGY PROSPECT AREA



DRILLING ACTIVITY


     The proposed drilling area lies in the Appalachian Plateau portion of
northern Tennessee. This historically oil producing area has seen recent
activity targeting zones that have yielded commercial gas production. Knox
Energy (KXE) has been actively drilling for natural gas for over three years and
has established production in a few locales within this vast area. Drilling is
ongoing as of the date of this report with recent wells displaying favorable
initial drilling and completion results.

                                       73





GEOLOGY

     STRATIGRAPHY, LITHOLOGY & DEPOSITION

     The depositional environments for the Mississippian carbonates range from
shelf to lagoon and near shore settings. The Devonian or Chattanooga Shale
formed in an organic rich sea offshore from the Catskill Delta.

     The Mississippian reservoirs consist of the Monteagle limestone, St. Louis
dolomite, Warsaw limey siltstone HIC OMITTED][GRAPHIC OMITTED] and the Ft. Payne
cherty limestone. The Chattanooga Shale underlies the Ft. Payne. Diagram
illustrates stratigraphic relationships.

     The primary target in all wells in this area is the MONTEAGLE LIMESTONE.
This limestone contains thick deposits of Oolites, which provide porosity as
high as 20%. Some wells have encountered as much as 30 feet of this reservoir.

     The DEVONIAN SHALE is another primary target in the area. This reservoir
underlies the Mississippian carbonates and is found in all wells throughout the
area. This formation is not only a reservoir when fractured, but is considered
the source of the hydrocarbons found in the overlying carbonates.

     Secondary targets may also show development. The FT. PAYNE is the primary
reservoir for the oil in adjacent fields found north and west of the prospect
area. The ST. LOUIS and WARSAW reservoirs have been encountered less often, but
could be considerable contributors in yet to be developed parts of the vast
prospect area.

     RESERVOIR CHARACTERISTICS

     Petroleum reservoirs are formed by the presence of an impermeable barrier
trapping commercial quantities of natural gas or oil in a more permeable medium.
In the Mississippian carbonate reservoirs this occurs in two ways. One way is
when ooids (carbonate sands) are formed and deposited (oolites) and are encased
in less permeable limestones. Another way is when limestone changes to dolomite
during a change ("diagenesis") at the atomic level of the rock.

     Electric well logs (right) can be used in conjunction with production to
interpret reservoir parameters. When the carbonates in the Mississippian
reservoirs develop porosity in excess of 5%, the permeability of the reservoir
can become great enough to allow commercial production of natural gas. When
small, naturally occurring cracks or fractures exist in the Chattanooga Shale,
permeability of the reservoir is enhanced. Audio logs can detect the small
amounts of natural gas that flow from the shale.

PRODUCTION

     The Tennessee Knox Energy prospect area produces from several reservoirs of
different age and type. Each well has a unique combination of these reservoirs
yielding different production declines. While Atlas anticipates production from
each reservoir to be comparable to like reservoirs historically produced
throughout the Appalachian Basin, a model decline curve for this prospect area
is not included due to the multiple sets of commingled reservoirs exclusively
found in this area.

CONCLUSION

     UEDC has conducted a geologic feasibility study of the prospect area for
ATLAS AMERICA PUBLIC #15-2006(B) L.P., which will consist of developmental
drilling of Mississippian and Devonian reservoirs in Scott, Anderson and Morgan
Counties of Tennessee. It is the professional opinion of UEDC that the drilling
of the twenty-seven (27) wells by ATLAS AMERICA PUBLIC #15-2006(B) L.P. is
supported by sufficient geologic and engineering data.

     For the purpose of this evaluation, UEDC did not visit any leaseholds or
inspect any of the associated production equipment. Likewise, UEDC has no
knowledge as to the validity of title, liabilities, or corporate matters
affecting these properties. UEDC does not warrant individual well performance.

            acquire any type of ownership interest in a producing property,
            including, but not limited to, working interests, royalties, or
            production payments. A program which spends at least 90% of capital
            contributions and funds borrowed (excluding offering and
            organizational expenses) in the above described activities is
            presumed to be a production purchase or income program.

      46.   "Program" means one or more limited or general partnerships or other
            investment vehicles formed, or to be formed, for the primary purpose
            of:

      47.   "Prospect" means an area covering lands which are believed by the
            Managing General Partner to contain subsurface structural or
            stratigraphic conditions making it susceptible to the accumulations
            of hydrocarbons in commercially productive quantities at one or more
            Horizons. The area, which may be different for different Horizons,
            shall be:

            (i)   designated by the Managing General Partner in writing before
                  the conduct of Partnership operations; and

                                        7


            (ii)  enlarged or contracted from time to time on the basis of

                  limits of the associated hydrocarbon reserves and to include
                  all acreage encompassed therein.

            If the well to be drilled by the Partnership is to a Horizon
            containing Proved Reserves, then a "Prospect" for a particular
            Horizon may be limited to the minimum area permitted by state law or
            local practice, whichever is applicable, to protect against drainage
            from adjacent wells. Subject to the foregoing sentence, "Prospect"
            shall be deemed the drilling or spacing unit for the Clinton/Medina
            geological formation and the Mississippian and/or Upper Devonian
            Sandstone reservoirs in Ohio, Pennsylvania, and New York and the
            Mississippian Carbonate or the Devonian Shale reservoirs in
            Anderson, Campbell, Morgan, Roane and Scott Counties, Tennessee.

      48.   "Prospectus" means the Prospectus included in the Registration
            Statement on Form S-1 relating to the offer and sale of the Units
            which has been filed with the Securities and Exchange Commission
            (the "Commission") under the Securities Act of 1933, as amended (the
            "Act"). As used in this Agreement, the terms "Prospectus" and
            "Registration Statement" refer solely to the Prospectus and
            Registration Statement, as amended, described above, except that:

            (i)   from and after the date on which any post-effective amendment
                  to the Registration Statement is declared effective by the
                  Commission, the term "Registration Statement" shall refer to
                  the Registration Statement as amended by that post-effective
                  amendment, and the term "Prospectus" shall refer to the
                  Prospectus then forming a part of the Registration Statement;
                  and

            (ii)  if the Prospectus filed pursuant to Rule 424(b) or (c)
                  promulgated by the Commission under the Act differs from the
                  Prospectus on file with the Commission at the time the
                  Registration Statement or any post-effective amendment thereto
                  shall have become effective, the term "Prospectus" shall refer
                  to the Prospectus filed pursuant thereto from and after the
                  date on which it was filed.

      49.   "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.

      50.   "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 only by contractual arrangements, but
            not on escalations based upon future conditions.

            (i)   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:

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

                  (b)   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.

            (ii)  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.

                                        8


            (iii) Estimates of proved reserves do not include the following:

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

                  (b)   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;

                  (c)   crude oil, natural gas, and natural gas liquids, that
                        may occur in undrilled prospects; and

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

      51.   "Proved Undeveloped Reserves" means reserves that are expected to be
            recovered from either:

            (i)   new wells on undrilled acreage; or

            (ii)  from existing wells where a relatively major expenditure is
                  required for recompletion.

            Reserves on undrilled acreage shall be 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.

      52.   "Reimbursement for Permissible Non-Cash Compensation" means a .5%
            accountable reimbursement for permissible non-cash compensation,
            which includes:

            (i)   an accountable reimbursement for training and education
                  meetings for associated persons of the Selling Agents;

            (ii)  gifts that do not exceed $100 per year and are not
                  preconditioned on achievement of a sales target;

            (iii) an occasional meal, a ticket to a sporting event or the
                  theater, or comparable entertainment which is neither so
                  frequent nor so extensive as to raise any question of
                  propriety and is not preconditioned on achievement of a sales
                  target; and

            (iv)  contributions to a non-cash compensation arrangement between a
                  Selling Agent and its associated persons, provided that
                  neither the Managing General Partner nor the Dealer-Manager
                  directly or indirectly participates in the Selling Agent's
                  organization of a permissible non-cash compensation
                  arrangement.

      53.   "Roll-Up" means a transaction involving the acquisition, merger,
            conversion or consolidation, either directly or indirectly, of the
            Partnership and the issuance of securities of a Roll-Up Entity. The
            term does not include:

            (i)   a transaction involving securities of the Partnership that
                  have been listed for at least 12 months on a national exchange
                  or traded through the National Association of Securities
                  Dealers Automated Quotation National Market System; or

                                        9


            (ii)  a transaction involving the conversion to corporate, trust or
                  association form of only the Partnership if, as a consequence
                  of the transaction, there will be no significant adverse
                  change in any of the following:

            optional subscriptions for Units as a Participant under
            ss.3.03(b)(1).

Execution of the Managing General Partner Signature Page serves as an agreement

3.04(a). MANAGING GENERAL PARTNER'S REQUIRED CAPITAL CONTRIBUTIONS. The Managing
General Partner, as a general partner and not as a Participant, is required to

under this Agreement, including contributing to the Partnership the Leases which

      (i)   the liquidation of the Partnership; or

      (ii)  the liquidation of the Managing General Partner's interest in the
            Partnership.

This shall be determined after taking into account all adjustments for the
Partnership's taxable year during which the liquidation occurs, other than
adjustments made pursuant to this requirement, by the end of the taxable year in
which its interest in the Partnership is liquidated or, if later, within 90 days
after the date of the liquidation.

3.04(c). MANAGING GENERAL PARTNER'S PARTNERSHIP INTEREST FOR CAPITAL
CONTRIBUTIONS. The interest of the Managing General Partner, as Managing General
Partner and not as a Participant, in the capital and profits of the Partnership
is fully vested and nonforfeitable as of the date of the formation of the
Partnership and is in consideration for, and is the only consideration for, its
required Capital Contributions to the Partnership.

3.04(d). MANAGING GENERAL PARTNER'S RIGHT TO ASSIGN ITS PARTNERSHIP INTEREST.
Subject to ss.5.01(b)(4)(a) regarding the Managing General Partner's
subordination obligation, the Managing General Partner has the right at any
time, in its discretion, without the consent of the Participants, and without
affecting the allocation of costs and revenues to the Participants or the
Managing General Partner's voting rights under this Agreement, to sell,
contribute, exchange or otherwise transfer all or any portion of its interest as
Managing General Partner or as a Participant (if it purchases Units) in the
Partnership, or any interest therein. In that event, except as otherwise may be
permitted under this Agreement, if the Affiliated transferee of the Managing
General Partner's transferred interest in the Partnership does not become a
substituted Managing General Partner in the Partnership, the Affiliated
transferee, as a partner in the Partnership for tax purposes only, shall have
the right to receive the share of the Partnership's profits, losses, income,
gains, deductions, credits and depletion allowances, or items thereof, and cash
distributions and returns of capital (including, but not limited to, cash
distributions and returns of capital on dissolution and liquidation of the
Partnership) to which the Managing General Partner would otherwise be entitled
under this Agreement with respect to its transferred interest in the
Partnership. Subject to the foregoing, the transfer of the Managing General
Partner's transferred interest in the Partnership to any of its Affiliates may
be made on any terms and conditions as the Managing General Partner determines,
in its discretion, and the Partnership and the Participants shall have no right
to receive or otherwise share in any consideration received by the Managing
General Partner from its Affiliates for the transfer of the Managing General
Partner's transferred interest in the Partnership. No transfer of the Managing
General Partner's transferred interest in the Partnership to its Affiliates
under this ss.3.04(d) shall require an accounting by the Managing General
Partner or the Partnership to the Participants.

                                       13


3.05. PAYMENT OF SUBSCRIPTIONS.

amount designated as the subscription price on the Subscription Agreement
executed by the Participant 100% in cash at the time of subscribing. A
Participant shall receive interest on the amount he pays from the time his
subscription proceeds are deposited in the escrow account, or the Partnership
account after the minimum number of Units have been received as provided in
ss.3.06(b), until the Offering Termination Date.

3.05(b)(2). ADDITIONAL REQUIRED CAPITAL CONTRIBUTIONS OF THE INVESTOR GENERAL
PARTNERS. Investor General Partners must make Capital Contributions to the
Partnership when called by the Managing General Partner, in addition to their
subscriptions, for their pro rata share of any Partnership obligations and
liabilities which are recourse to the Investor General Partners and are
represented by their ownership of Units before the conversion of Investor
General Units to Limited Partner Units under ss.6.01(b).

3.05(b)(3). DEFAULT PROVISIONS. The failure of an Investor General Partner to
timely make a required additional Capital Contribution under this section
results in his personal liability to the other Investor General Partners for the
amount in default. The remaining Investor General Partners, in proportion to
their respective number of Units, must pay the defaulting Investor General
Partner's share of Partnership liabilities and obligations called for by the
Managing General Partner. In that event, the remaining Investor General
Partners:

      (i)   shall have a first and preferred lien on the defaulting Investor
            General Partner's interest in the Partnership to secure payment of
            the amount in default plus interest at the legal rate;

      (ii)  shall be entitled to receive 100% of the defaulting Investor General
            Partner's cash distributions, in proportion to their respective
            number of Units, until the amount in default is recovered in full
            plus interest at the legal rate; and

      (iii) may commence legal action to collect the amount due plus interest at
            the legal rate.

3.06. PARTNERSHIP FUNDS.

3.06(a). FIDUCIARY DUTY. The Managing General Partner has a fiduciary
responsibility for the safekeeping and use of all funds and assets of the
Partnership, whether or not in the Managing General Partner's possession or
control. The Managing General Partner shall not employ, or permit another to
employ, the funds and assets in any manner except for the exclusive benefit of
the Partnership.

Neither this Agreement nor any other agreement between the Managing General
Partner and the Partnership shall contractually limit any fiduciary duty owed to
the Participants by the Managing General Partner under applicable law, except as
provided in ss.ss.4.01, 4.02, 4.03, 4.04, 4.05 and 4.06 of this Agreement.

3.06(b). SPECIAL ACCOUNT AFTER THE RECEIPT OF THE MINIMUM PARTNERSHIP
SUBSCRIPTIONS. Following the receipt of the minimum number of Units and breaking
escrow, the funds of the Partnership shall be held in a separate
interest-bearing account maintained for the Partnership and shall not be
commingled with funds of any other entity.

            proceeds which are a necessary and incidental part of a property
            acquisition transaction; and

      (v)   investments in entities established solely to limit the
            Partnership's liabilities associated with the ownership or operation
            of property or equipment, provided that duplicative fees and
            expenses shall be prohibited.

3.06(c)(2). PERMISSIBLE INVESTMENTS BEFORE INVESTMENT IN PARTNERSHIP ACTIVITIES.
After the Initial Closing Date and until proceeds from the offering are invested
in the Partnership's operations, the proceeds may be temporarily invested in
income producing short-term, highly liquid investments, in which there is
appropriate safety of principal, such as U.S. Treasury Bills.

      (ii)  credited towards the Managing General Partner's required Capital
            Contribution set forth in ss.3.04(a) at the Cost of the Lease,
            unless the Managing General Partner has cause to believe that Cost
            is materially more than the fair market value of the property, in
            which case the credit for the contribution must be made at a price
            not in excess of the fair market value.


A determination of fair market value must be:

      (i)   supported by an appraisal from an Independent Expert; and

      (ii)  maintained in the Partnership's records for six years along with
            associated supporting information.

Affiliates. They may either:

      (i)   retain and exploit the remaining interest for their own account; or

      (ii)  sell or otherwise dispose of all or a part of the remaining
            interest.

the Leases shall be for the benefit of the Managing General Partner or its
Affiliates to the exclusion of the Partnership.

4.01(a)(6). NO BREACH OF DUTY. Subject to the provisions of ss.4.03 and its

Operator or their Affiliates shall not be considered a breach of any obligation
owed by them to the Partnership or the Participants.

4.01(b). NO OVERRIDING ROYALTY INTERESTS. Neither the Managing General Partner,
the Operator nor any Affiliate shall retain any Overriding Royalty Interest on
the Leases acquired by the Partnership.

4.01(c). TITLE AND NOMINEE ARRANGEMENTS.

4.01(c)(1). LEGAL TITLE. Legal title to all Leases acquired by the Partnership
shall be held on a permanent basis in the name of the Partnership. However,
Partnership properties may be held temporarily in the name of:

      (iii) their Affiliates; or

      (iv)  in the name of any nominee designated by the Managing General
            Partner to facilitate the acquisition of the properties.

4.01(c)(2). MANAGING GENERAL PARTNER'S DISCRETION. The Managing General Partner

the Leases to be acquired by the Partnership acceptable for the purposes of the
Partnership. The Managing General Partner shall be free, however, to use its own
best judgment in waiving title requirements.

The Managing General Partner shall not be liable to the Partnership or to the
other parties for any mistakes of judgment; nor shall the Managing General

                  drilling and other activities of the Partnership;

to take any further action which the attorney-in-fact considers necessary or
advisable in connection with any of the foregoing powers and rights granted the

below:

      (i)   Audited financial statements of the Partnership, including a balance
            sheet and statements of income, cash flow, and Partners' equity,
            which shall be prepared on an accrual basis in accordance with
            generally accepted accounting principles with a reconciliation with

            independent public accountant selected by the Managing General
            Partner stating that his audit was made in accordance with generally
            accepted auditing standards and that in his opinion the financial
            statements present fairly the financial position, results of
            operations, partners' equity, and cash flows in accordance with
            generally accepted accounting principles. Semiannual reports are not
            required to be audited.


      (ii)  A summary itemization, by type and/or classification of the total
            fees and compensation, including any nonaccountable, fixed payment
            reimbursements for Administrative Costs and Operating Costs, paid
            by, or on behalf of, the Partnership to the Managing General
            Partner, the Operator, and their Affiliates. In addition,
            Participants shall be provided the percentage that the annual
            nonaccountable, fixed fee reimbursement for Administrative Costs
            bears to annual Partnership revenues.

            Also, the independent certified public accountant shall provide
            written attestation annually, which will be included in the annual
            report, that the method used to make allocations of the
            Partnership's Administrative Costs was consistent with the method
            described in ss.4.04(a)(2)(c) of this Agreement and that the total
            amount of Administrative Costs allocated did not materially exceed
            the amounts actually incurred by the Managing General Partner in

            General Partner subsequently decides to allocate Administrative
            Costs in a manner different from that described in ss.4.04(a)(2)(c)
            of this Agreement, then the change must be reported to the
            Participants together with an explanation of the reason for the
            change and the basis used for determining the reasonableness of the
            new allocation method.

            interest, including:



                                       21

            any, regarding the Prospects.

      (iv)  A list of the wells drilled or abandoned by the Partnership during
            the period of the report, indicating:

            (a)   whether each of the wells has or has not been completed;

            (b)   a statement of the cost of each well completed or abandoned;
                  and

      (v)   A description of all Farmouts, farmins, and joint ventures, made
            during the period of the report, including:

            (a)   the Managing General Partner's justification for the
                  arrangement; and

            (b)   a description of the material terms.

      (vi)  A schedule reflecting:

            (a)   the total Partnership costs;

            (b)   the costs paid by the Managing General Partner and the costs

            (c)   the total Partnership revenues;

            (d)   the revenues received or credited to the Managing General
                  Partner and the revenues received and credited to the
                  Participants; and

the SEC) within 45 days after the close of each quarterly fiscal period.

4.03(b)(2). TAX INFORMATION. The Partnership shall, by March 15 of each year,
prepare, or supervise the preparation of, and transmit to each Participant the
information needed for the Participant to file the following:

            (i)   his federal income tax return;

            (ii)  any required state income tax return; and

            (iii) any other reporting or filing requirements imposed by any
                  governmental agency or authority.

            (ii)  a summary of the computation of the present worth of the
                  reserves determined using:

                  (a)   a discount rate of 10%;

                  (b)   a constant price for the oil; and

                                       22


                  (c)   basing the price of natural gas on the existing natural
                        gas contracts;

            (iii) a statement of each Participant's interest in the reserves;
                  and

            (iv)  an estimate of the time required for the extraction of the
                  reserves with a statement that because of the time period
                  required to extract the reserves the present value of revenues
                  to be obtained in the future is less than if immediately
                  receivable.

The reserve computations shall be based on engineering reports prepared by the
Managing General Partner and reviewed by an Independent Expert.

Also, if any event reduces the Partnership's Proved Reserves by 10% or more,
excluding a reduction of reserves as a result of normal production, sales of
reserves, or natural gas or oil price changes, then a computation and estimate
of the amount of the reduction in reserves must be sent to each Participant
within 90 days after the Managing General Partner determines that such a
reduction in reserves has occurred.

4.03(b)(4). COST OF REPORTS. The cost of all reports described in this
ss.4.03(b) shall be paid by the Partnership as Direct Costs.

4.03(b)(5). PARTICIPANT ACCESS TO RECORDS. The Participants and/or their

that access to the list of Participants shall be subject to ss.4.03(b)(7) below.
The Participant may inspect and copy any of the records after giving adequate
notice to the Managing General Partner at any reasonable time.

Notwithstanding the foregoing, the Managing General Partner may keep logs, well
reports, and other drilling and operating data confidential for reasonable
periods of time. The Managing General Partner may release information concerning
the operations of the Partnership to the sources that are customary in the
industry or required by rule, regulation, or order of any regulatory body.

            established in connection with an investment in the Partnership; and

      (ii)  any appraisal of the fair market value of the Leases as set forth in
            ss.4.01(a)(4) or fair market value of any producing property as set
            forth in ss.4.03(d)(3).

to the list of Participants:

      (i)   an alphabetical list of the names, addresses, and business telephone
            numbers of the Participants along with the number of Units held by
            each of them (the "Participant List") must be maintained as a part
            of the Partnership's books and records and be available for
            inspection by any Participant or his designated agent at the home
            office of the Partnership on the Participant's request;

      (ii)  the Participant List must be updated at least quarterly to reflect
            changes in the information contained in the Participant List;

      (iii) a copy of the Participant List must be mailed to any Participant
            requesting the Participant List within 10 days of the written
            request, printed in alphabetical order on white paper, and in a
            readily readable type size in no event smaller than 10-point type
            and a reasonable charge for copy work will be charged by the
            Partnership;

      (iv)  the purposes for which a Participant may request a copy of the
            Participant List include, without limitation, matters relating to
            Participant's voting rights under this Agreement and the exercise of
            Participant's rights under the federal proxy laws; and

                                       23


      (v)   if the Managing General Partner neglects or refuses to exhibit,
            produce, or mail a copy of the Participant List as requested, the
            Managing General Partner shall be liable to any Participant
            requesting the list for the costs, including attorneys fees,
            incurred by that Participant for compelling the production of the
            Participant List, and for actual damages suffered by any Participant
            by reason of the refusal or neglect. It shall be a defense that the
            actual purpose and reason for the request for inspection or for a
            copy of the Participant List is to secure the list of Participants
            or other information for the purpose of selling the list or
            information or copies of the list, or of using the same for a
            commercial purpose other than in the interest of the applicant as a
            Participant relative to the affairs of the Partnership. The Managing
            General Partner will require the Participant requesting the
            Participant List to represent in writing that the list was not
            requested for a commercial purpose unrelated to the Participant's
            interest in the Partnership. The remedies provided under this
            subsection to Participants requesting copies of the Participant List
            are in addition to, and shall not in any way limit, other remedies
            available to Participants under federal law or the laws of any
            state.

4.03(b)(8). STATE FILINGS. Concurrently with their transmittal to Participants,
and as required, the Managing General Partner shall file a copy of each report
provided for in this ss.4.03(b) with:

      (i)   the California Commissioner of Corporations;

      (ii)  the Arizona Corporation Commission;

      (iii) the Alabama Securities Commission; and

      (iv)  the securities commissions of other states which request the report.

4.03(c). MEETINGS OF PARTICIPANTS.

4.03(c)(1). PROCEDURE FOR A PARTICIPANT MEETING.

4.03(c)(1)(a). MEETINGS MAY BE CALLED BY MANAGING GENERAL PARTNER OR
PARTICIPANTS. Meetings of the Participants may be called as follows:

      (i)   by the Managing General Partner; or

      (ii)  by Participants whose Units equal 10% or more of the total Units for
            any matters for which Participants may vote.

The call for a meeting by Participants shall be deemed to have been made on
receipt by the Managing General Partner of a written request from holders of the
requisite percentage of Units stating the purpose(s) of the meeting.

4.03(c)(1)(b). NOTICE REQUIREMENT. The Managing General Partner shall deposit in
the United States mail within 15 days after the receipt of the request, written
notice to all Participants of the meeting and the purpose of the meeting. The
meeting shall be held on a date not less than 30 days nor more than 60 days
after the date of the mailing of the notice, at a reasonable time and place.

Notwithstanding the foregoing, the date for notice of the meeting may be
extended for a period of up to 60 days if, in the opinion of the Managing
General Partner, the additional time is necessary to permit preparation of proxy
or information statements or other documents required to be delivered in
connection with the meeting by the SEC or other regulatory authorities.

4.03(c)(1)(c). MAY VOTE BY PROXY. Participants shall have the right to vote at
any Participant meeting either:

      (i)   in person; or

      (ii)  by proxy.

                                       24


4.03(c)(2). SPECIAL VOTING RIGHTS. At the request of Participants whose Units
equal 10% or more of the total Units, the Managing General Partner shall call
for a vote by Participants. Each Unit is entitled to one vote on all matters,
and each fractional Unit is entitled to that fraction of one vote equal to the
fractional interest in the Unit. Participants whose Units equal a majority of
the total Units may, without the concurrence of the Managing General Partner or
its Affiliates, vote to:

      (i)   dissolve the Partnership;

      (ii)  remove the Managing General Partner and elect a new Managing General
            Partner;

      (iii) elect a new Managing General Partner if the Managing General Partner
            elects to withdraw from the Partnership;

      (iv)  remove the Operator and elect a new Operator;

      (v)   approve or disapprove the sale of all or substantially all of the
            assets of the Partnership;

      (vi)  cancel any contract for services with the Managing General Partner,
            the Operator, or their Affiliates without penalty on 60 days notice;
            and

      (vii) amend this Agreement; provided however:

            (a)   any amendment may not increase the duties or liabilities of
                  any Participant or the Managing General Partner or increase or
                  decrease the profit or loss sharing or required Capital
                  Contribution of any Participant or the Managing General
                  Partner without the approval of the Participant or the
                  Managing General Partner; and

            (b)   any amendment may not affect the classification of Partnership
                  income and loss for federal income tax purposes without the
                  unanimous approval of all Participants.

4.03(c)(3). RESTRICTIONS ON MANAGING GENERAL PARTNER'S VOTING RIGHTS. With
respect to Units owned by the Managing General Partner or its Affiliates, the
Managing General Partner and its Affiliates may vote or consent on all matters
other than the following:

      (i)   the matters set forth in ss.4.03(c)(2)(ii) and (iv) above; or

      (ii)  any transaction between the Partnership and the Managing General
            Partner or its Affiliates.

In determining the requisite percentage in interest of Units necessary to
approve any Partnership matter on which the Managing General Partner and its
Affiliates may not vote or consent, any Units owned by the Managing General
Partner and its Affiliates shall not be included.

4.03(c)(4). RESTRICTIONS ON LIMITED PARTNER VOTING RIGHTS. The exercise by the
Limited Partners of the rights granted Participants under ss.4.03(c), except for
the special voting rights granted Participants under ss.4.03(c)(2), shall be
subject to the prior legal determination that the grant or exercise of the
powers will not adversely affect the limited liability of Limited Partners.
Notwithstanding the foregoing, if in the opinion of counsel to the Partnership
the legal determination is not necessary under Delaware law to maintain the
limited liability of the Limited Partners, then it shall not be required. A
legal determination under this paragraph may be made either pursuant to:

      (i)   an opinion of counsel, the counsel being independent of the
            Partnership and selected on the vote of Limited Partners whose Units
            equal a majority of the total Units held by Limited Partners; or

      (ii)  a declaratory judgment issued by a court of competent jurisdiction.

The Investor General Partners may exercise the rights granted to the
Participants whether or not the Limited Partners can participate in the vote if
the Investor General Partners represent the requisite percentage of Units
necessary to take the action.

                                       25


4.03(d). TRANSACTIONS WITH THE MANAGING GENERAL PARTNER.

4.03(d)(1). TRANSFER OF EQUAL PROPORTIONATE INTEREST. When the Managing General
Partner or an Affiliate (excluding another Program in which the interest of the
Managing General Partner or its Affiliates is substantially similar to or less
than their interest in the Partnership) sells, transfers or conveys any natural
gas, oil or other mineral interests or property to the Partnership, it must, at
the same time, sell, transfer or convey to the Partnership an equal
proportionate interest in all its other property in the same Prospect.
Notwithstanding, a Prospect shall be deemed to consist of the drilling or
spacing unit on which the well will be drilled by the Partnership, which is the
minimum area permitted by state law or local practice on which one well may be
drilled, if the following two conditions are met:

      (i)   the geological feature to which the well will be drilled contains
            Proved Reserves; and

      (ii)  the drilling or spacing unit protects against drainage.

With respect to a Prospect located in Ohio, Pennsylvania and New York on which a
well will be drilled by the Partnership to test the Clinton/Medina geological
formation or the Mississippian and/or Upper Devonian Sandstone reservoirs, and
with respect to a Prospect located in Anderson, Campbell, Morgan, Roane and
Scott Counties, Tennessee on which a well will be drilled to test the
Mississippian carbonate or Devonian Shale reservoirs, a Prospect shall be deemed
to consist of the drilling and spacing unit if it meets the test in the
preceding sentence. Additionally, for a period of five years after the drilling
of the Partnership Well neither the Managing General Partner nor its Affiliates
may drill any well:

      (i)   in the Clinton/Medina geological formation within 1,650 feet of an
            existing Partnership Well in Pennsylvania or within 1,000 feet of an
            existing Partnership Well in Ohio; or

      (ii)  in the Mississippian and/or Upper Devonian Sandstone reservoirs in
            Fayette, Greene and Westmoreland Counties, Pennsylvania, within
            1,000 feet from a producing Partnership Well, although the
            Partnership may drill a new well or re-enter an existing well which
            is closer than 1,000 feet to a plugged and abandoned well.

If the Partnership abandons its interest in a well, then this restriction will
continue for one year following the abandonment.

If the area constituting the Partnership's Prospect is subsequently enlarged to
encompass any area in which the Managing General Partner or an Affiliate
(excluding another Program in which the interest of the Managing General Partner
or its Affiliates is substantially similar to or less than their interest in the
Partnership) owns a separate property interest and the activities of the
Partnership were material in establishing the existence of Proved Undeveloped
Reserves that are attributable to the separate property interest, then the
separate property interest or a portion thereof must be sold, transferred, or
conveyed to the Partnership as set forth in this section and ss.ss.4.01(a)(4)
and 4.03(d)(2).

Notwithstanding the foregoing, Prospects in the Clinton/Medina geological
formation, the Mississippian and/or Upper Devonian Sandstone reservoirs, the
Mississippian carbonate or Devonian Shale reservoirs, or any other formation or
reservoir shall not be enlarged or contracted if the Prospect was limited to the
drilling or spacing unit because the well was being drilled to Proved Reserves
in the geological formation and the drilling or spacing unit protected against
drainage.

4.03(d)(2). TRANSFER OF LESS THAN THE MANAGING GENERAL PARTNER'S AND ITS
AFFILIATES' ENTIRE INTEREST. A sale, transfer or a conveyance to the Partnership
of less than all of the ownership of the Managing General Partner or an
Affiliate (excluding another Program in which the interest of the Managing
General Partner or its Affiliates is substantially similar to or less than their
interest in the Partnership) in any Prospect shall not be made unless:

      (i)   the interest retained by the Managing General Partner or the
            Affiliate is a proportionate Working Interest;

      (ii)  the respective obligations of the Managing General Partner or its
            Affiliates and the Partnership are substantially the same after the
            sale of the interest by the Managing General Partner or its
            Affiliates; and

      (iii) the Managing General Partner's interest in revenues does not exceed
            the amount proportionate to its retained Working Interest.

                                       26


This section does not prevent the Managing General Partner or its Affiliates
from subsequently dealing with their retained interest as they may choose with
unaffiliated parties or Affiliated partnerships.

4.03(d)(3). LIMITATIONS ON SALE OF UNDEVELOPED AND DEVELOPED LEASES TO THE
MANAGING GENERAL PARTNER. Other than another Program managed by the Managing
General Partner and its Affiliates as set forth in ss.ss.4.03(d)(5) and
4.03(d)(9), the Managing General Partner and its Affiliates shall not receive a
Farmout or purchase any undeveloped Leases from the Partnership other than at
the higher of Cost or fair market value.

The Managing General Partner and its Affiliates, other than an Affiliated Income
Program, shall not purchase any producing natural gas or oil property from the
Partnership unless:

      (i)   the sale is in connection with the liquidation of the Partnership;
            or

      (ii)  the Managing General Partner's well supervision fees under the
            Drilling and Operating Agreement for the well have exceeded the net
            revenues of the well, determined without regard to the Managing
            General Partner's well supervision fees for the well, for a period
            of at least three consecutive months.

In both (i) and (ii), the sale must be at fair market value supported by an
appraisal of an Independent Expert selected by the Managing General Partner.

4.03(d)(4). LIMITATIONS ON ACTIVITIES OF THE MANAGING GENERAL PARTNER AND ITS
AFFILIATES ON LEASES ACQUIRED BY THE PARTNERSHIP. During a period of five years
after the Offering Termination Date of the Partnership, if the Managing General
Partner or any of its Affiliates (excluding another Program in which the
interest of the Managing General Partner or its Affiliates is substantially
similar to or less than their interest in the Partnership) proposes to acquire
an interest from an unaffiliated person in a Prospect in which the Partnership
possesses an interest or in a Prospect in which the Partnership's interest has
been terminated without compensation within one year preceding the proposed
acquisition, then the following conditions shall apply:

      (i)   if the Managing General Partner or the Affiliate (excluding another
            Program in which the interest of the Managing General Partner or its
            Affiliates is substantially similar to or less than their interest
            in the Partnership) does not currently own property in the Prospect
            separately from the Partnership, then neither the Managing General
            Partner nor the Affiliate shall be permitted to purchase an interest
            in the Prospect; and

      (ii)  if the Managing General Partner or the Affiliate (excluding another
            Program in which the interest of the Managing General Partner or its
            Affiliates is substantially similar to or less than their interest
            in the Partnership) currently owns a proportionate interest in the
            Prospect separately from the Partnership, then the interest to be
            acquired shall be divided between the Partnership and the Managing
            General Partner or the Affiliate in the same proportion as is the
            other property in the Prospect. Provided, however, if cash or
            financing is not available to the Partnership to enable it to
            complete a purchase of the additional interest to which it is
            entitled, then neither the Managing General Partner nor the
            Affiliate shall be permitted to purchase any additional interest in
            the Prospect.

4.03(d)(5). TRANSFER OF LEASES BETWEEN AFFILIATED LIMITED PARTNERSHIPS. The
transfer of an undeveloped Lease from the Partnership to another drilling
Program sponsored or managed by the Managing General Partner or its Affiliates
must be made at fair market value if the undeveloped Lease has been held for
more than two years. Otherwise, if the Managing General Partner deems it to be
in the best interest of the Partnership, the transfer may be made at Cost.

An Affiliated Income Program may purchase a producing natural gas and oil
property from the Partnership at any time at:

      (i)   fair market value as supported by an appraisal from an Independent
            Expert if the property has been held by the Partnership for more
            than six months or significant expenditures have been made in
            connection with the property; or

      (ii)  Cost as adjusted for intervening operations if the Managing General
            Partner deems it to be in the best interest of the Partnership.

                                       27


However, these prohibitions shall not apply to joint ventures or Farmouts among
Affiliated partnerships, provided that:

      (i)   the respective obligations and revenue sharing of all parties to the
            transaction are substantially the same; and

      (ii)  the compensation arrangement or any other interest or right of
            either the Managing General Partner or its Affiliates is the same in
            each Affiliated partnership or if different, the aggregate
            compensation of the Managing General Partner or the Affiliate is
            reduced to reflect the lower compensation arrangement.

4.03(d)(6). SALE OF ALL ASSETS. The sale of all or substantially all of the
assets of the Partnership, including without limitation, Leases, wells,
equipment and production therefrom, shall be made only with the consent of
Participants whose Units equal a majority of the total Units.

4.03(d)(7). SERVICES.

4.03(d)(7)(a). COMPETITIVE RATES. The Managing General Partner and any Affiliate
shall not render to the Partnership any oil field, equipage, or other services
nor sell or lease to the Partnership any equipment or related supplies unless:

      (i)   the person is engaged, independently of the Partnership and as an
            ordinary and ongoing business, in the business of rendering the
            services or selling or leasing the equipment and supplies to a
            substantial extent to other persons in the natural gas and oil
            industry in addition to the partnerships in which the Managing
            General Partner or an Affiliate has an interest; and

      (ii)  the compensation, price, or rental therefor is competitive with the
            compensation, price, or rental of other persons in the area engaged
            in the business of rendering comparable services or selling or
            leasing comparable equipment and supplies which could reasonably be
            made available to the Partnership.

If the person is not engaged in such a business, then the compensation, price or
rental shall be the Cost of the services, equipment or supplies to the person or
the competitive rate which could be obtained in the area, whichever is less.

4.03(d)(7)(b). IF NOT DISCLOSED IN THE PROSPECTUS OR THIS AGREEMENT THEN
SERVICES BY THE MANAGING GENERAL PARTNER MUST BE DESCRIBED IN A SEPARATE
CONTRACT AND CANCELABLE. Any services for which the Managing General Partner or
an Affiliate is to receive compensation other than those described in this
Agreement or the Prospectus shall be set forth in a written contract which
precisely describes the services to be rendered and all compensation to be paid.
These contracts shall be cancelable without penalty on 60 days written notice by
Participants whose Units equal a majority of the total Units.

4.03(d)(8). LOANS.

4.03(d)(8)(a). NO LOANS FROM THE PARTNERSHIP. No loans or advances shall be made
by the Partnership to the Managing General Partner or any Affiliate.

4.03(d)(8)(b). LOANS TO THE PARTNERSHIP. Neither the Managing General Partner
nor any Affiliate shall loan money to the Partnership if the interest to be
charged exceeds either:

      (i)   the Managing General Partner's or the Affiliate's interest cost; or

      (ii)  that which would be charged to the Partnership, without reference to
            the Managing General Partner's or the Affiliate's financial
            abilities or guarantees, by unrelated lenders, on comparable loans
            for the same purpose.

Neither the Managing General Partner nor any Affiliate shall receive points or
other financing charges or fees, regardless of the amount, although the actual
amount of the charges incurred from third-party lenders may be reimbursed to the
Managing General Partner or the Affiliate.

4.03(d)(9). FARMOUTS. The Managing General Partner shall not enter into a
Farmout to avoid its paying its share of costs related to drilling an
undeveloped Lease. The Partnership shall not Farmout an undeveloped Lease or
well activity to the Managing General Partner or its Affiliates except as set
forth in ss.4.03(d)(3). Notwithstanding, this restriction shall not apply to
Farmouts between the Partnership and another partnership managed by the Managing
General Partner or its Affiliates, either separately or jointly, provided that
the respective obligations and revenue sharing of all parties to the
transactions are substantially the same and the compensation arrangement or any
other interest or right of the Managing General Partner or its Affiliates is the
same in each partnership, or, if different, the aggregate compensation of the
Managing General Partner and its Affiliates is reduced to reflect the lower
compensation agreement.

                                       28


The Partnership may Farmout an undeveloped lease or well activity only if the
Managing General Partner, exercising the standard of a prudent operator,
determines that:

      (i)   the Partnership lacks the funds to complete the oil and gas
            operations on the Lease or well and cannot obtain suitable
            financing;

      (ii)  drilling on the Lease or the intended well activity would
            concentrate excessive funds in one location, creating undue risks to
            the Partnership;

      (iii) the Leases or well activity have been downgraded by events occurring
            after assignment to the Partnership so that development of the
            Leases or well activity would not be desirable; or

      (iv)  the best interests of the Partnership would be served.

If the Partnership Farmouts a Lease or well activity, the Managing General
Partner must retain on behalf of the Partnership the economic interests and
concessions as a reasonably prudent oil and gas operator would or could retain
under the circumstances prevailing at the time, consistent with industry
practices.

4.03(d)(10). NO COMPENSATING BALANCES. Neither the Managing General Partner nor
any Affiliate shall use the Partnership's funds as compensating balances for its
own benefit.

4.03(d)(11). FUTURE PRODUCTION. Neither the Managing General Partner nor any
Affiliate shall commit the future production of a well developed by the
Partnership exclusively for its own benefit.

4.03(d)(12). MARKETING ARRANGEMENTS. Subject to ss.4.06(c), all benefits from
marketing arrangements or other relationships affecting the property of the
Managing General Partner or its Affiliates and the Partnership shall be fairly
and equitably apportioned according to the respective interests of each in the
property. The Managing General Partner shall treat all wells in a geographic
area equally concerning to whom and at what price the Partnership's natural gas
and oil will be sold and to whom and at what price the natural gas and oil of
other natural gas and oil Programs which the Managing General Partner has
sponsored or will sponsor will be sold. For example, each seller of natural gas
and oil in a given area will be paid a weighted average selling price for all
natural gas and oil sold in that geographic area. The Managing General Partner,
in its sole discretion, shall determine what constitutes a geographic area.

4.03(d)(13). ADVANCE PAYMENTS. Advance payments by the Partnership to the
Managing General Partner and its Affiliates are prohibited except when advance
payments are required to secure the tax benefits of prepaid Intangible Drilling
Costs for a business purpose as set forth in the Drilling and Operating
Agreement.

4.03(d)(14). NO REBATES. No rebates or give-ups may be received by the Managing
General Partner or any Affiliate nor may the Managing General Partner or any
Affiliate participate in any reciprocal business arrangements which would
circumvent these guidelines.

4.03(d)(15). PARTICIPATION IN OTHER PARTNERSHIPS. If the Partnership
participates in other partnerships or joint ventures (multi-tier arrangements),
then the terms of any of these arrangements shall not result in the
circumvention of any of the requirements or prohibitions contained in this
Agreement, including the following:

      (i)   there shall be no duplication or increase in Organization and
            Offering Costs, the Managing General Partner's compensation,
            Partnership expenses or other fees and costs;

                                       29


      (ii)  there shall be no substantive alteration in the fiduciary and
            contractual relationship between the Managing General Partner and
            the Participants; and

      (iii) there shall be no diminishment in the voting rights of the
            Participants.

4.03(d)(16). ROLL-UP LIMITATIONS.

4.03(d)(16)(a). REQUIREMENT FOR APPRAISAL AND ITS ASSUMPTIONS. In connection
with a proposed Roll-Up, an appraisal of all Partnership assets shall be
obtained from a competent Independent Expert. If the appraisal will be included
in a prospectus used to offer securities of a Roll-Up Entity, then the appraisal
shall be filed with the SEC and the Administrator as an exhibit to the
registration statement for the offering. Thus, an issuer using the appraisal
shall be subject to liability for violation of Section 11 of the Securities Act
of 1933 and comparable provisions under state law for any material
misrepresentations or material omissions in the appraisal.

Partnership assets shall be appraised on a consistent basis. The appraisal shall
be based on all relevant information, including current reserve estimates
prepared as set forth in ss.4.03(b)(3), and shall indicate the value of the
Partnership's assets as of a date immediately before the announcement of the
proposed Roll-Up transaction. The appraisal shall assume an orderly liquidation
of the Partnership's assets over a 12-month period.

The terms of the engagement of the Independent Expert shall clearly state that
the engagement is for the benefit of the Partnership and the Participants. A
summary of the independent appraisal, indicating all material assumptions
underlying the appraisal, shall be included in a report to the Participants in
connection with a proposed Roll-Up.

4.03(d)(16)(b). RIGHTS OF PARTICIPANTS WHO VOTE AGAINST PROPOSAL. In connection
with a proposed Roll-Up, Participants who vote "no" on the proposal shall be
offered the choice of:

      (i)   accepting the securities of the Roll-Up Entity offered in the
            proposed Roll-Up; or

      (ii)  one of the following:

            (a)   remaining as Participants in the Partnership and preserving
                  their Units in the Partnership on the same terms and
                  conditions as existed previously; or

            (b)   receiving cash in an amount equal to the Participants' pro
                  rata share of the appraised value of the net assets of the
                  Partnership based on their respective number of Units.

4.03(d)(16)(c). NO ROLL-UP IF DIMINISHMENT OF VOTING RIGHTS. The Partnership
shall not participate in any proposed Roll-Up which, if approved, would result
in the diminishment of any Participant's voting rights under the Roll-Up
Entity's chartering agreement. In no event shall the democracy rights of
Participants in the Roll-Up Entity be less than those provided for under
ss.ss.4.03(c)(1) and 4.03(c)(2) of this Agreement. If the Roll-Up Entity is a
corporation, then the democracy rights of Participants shall correspond to the
democracy rights provided for in this Agreement to the greatest extent possible.

4.03(d)(16)(d). NO ROLL-UP IF ACCUMULATION OF SHARES WOULD BE IMPEDED. The
Partnership shall not participate in any proposed Roll-Up transaction which
includes provisions that would operate to materially impede or frustrate the
accumulation of shares by any purchaser of the securities of the Roll-Up Entity,
except to the minimum extent necessary to preserve the tax status of the Roll-Up
Entity. The Partnership shall not participate in any proposed Roll-Up
transaction which would limit the ability of a Participant to exercise the
voting rights of its securities of the Roll-Up Entity on the basis of the number
of Units held by that Participant.

4.03(d)(16)(e). NO ROLL-UP IF ACCESS TO RECORDS WOULD BE LIMITED. The
Partnership shall not participate in a Roll-Up in which Participants' rights of
access to the records of the Roll-Up Entity will be less than those provided for
under ss.ss.4.03(b)(5), 4.03(b)(6) and 4.03(b)(7) of this Agreement.

4.03(d)(16)(f). COST OF ROLL-UP. The Partnership shall not participate in any
proposed Roll-Up transaction in which any of the costs of the transaction would
be borne by the Partnership if Participants whose Units equal 66% of the total
Units do not vote to approve the proposed Roll-Up.

                                       30


4.03(d)(16)(g). ROLL-UP APPROVAL. The Partnership shall not participate in a
Roll-Up transaction unless the Roll-Up transaction is approved by Participants
whose Units equal 66% of the total Units.

4.03(d)(17). DISCLOSURE OF BINDING AGREEMENTS. Any agreement or arrangement
which binds the Partnership must be disclosed in the Prospectus.

4.03(d)(18). TRANSACTIONS MUST BE FAIR AND REASONABLE. Neither the Managing
General Partner nor any Affiliate shall sell, transfer, or convey any property
to or purchase any property from the Partnership, directly or indirectly, except
under transactions that are fair and reasonable, nor take any action with
respect to the assets or property of the Partnership which does not primarily
benefit the Partnership.

4.04. DESIGNATION, COMPENSATION AND REMOVAL OF MANAGING GENERAL PARTNER AND
REMOVAL OF OPERATOR.

4.04(a). MANAGING GENERAL PARTNER.

4.04(a)(1). TERM OF SERVICE. Atlas shall serve as the Managing General Partner
of the Partnership until either it:

      (i)   is removed pursuant to ss.4.04(a)(3); or

      (ii)  withdraws pursuant to ss.4.04(a)(3)(f).

4.04(a)(2). COMPENSATION OF MANAGING GENERAL PARTNER. In addition to the
compensation set forth in ss.ss.4.01(a)(4) and 4.02(d)(1), the Managing General
Partner shall receive the compensation set forth in ss.ss.4.04(a)(2)(b) through
4.04(a)(2)(g).

4.04(a)(2)(a). CHARGES MUST BE NECESSARY AND REASONABLE. Charges by the Managing
General Partner for goods and services must be fully supportable as to:

      (i)   the necessity of the goods and services; and

      (ii)  the reasonableness of the amount charged.

All actual and necessary expenses incurred by the Partnership may be paid out of
the Partnership's subscription proceeds and revenues.

4.04(a)(2)(b). DIRECT COSTS. The Managing General Partner and its Affiliates
shall be reimbursed for all Direct Costs. Direct Costs, however, shall be billed
directly to and paid by the Partnership to the extent practicable.

4.04(a)(2)(c). ADMINISTRATIVE COSTS. The Managing General Partner shall receive
a nonaccountable, fixed payment reimbursement for its Administrative Costs of
$75 per well per month. The nonaccountable, fixed payment reimbursement of $75
per well per month shall be subject to the following:

      (i)   it shall not be increased in amount during the term of the
            Partnership;

      (ii)  it shall be proportionately reduced to the extent the Partnership
            acquires less than 100% of the Working Interest in the well;

      (iii) it shall be the entire payment to reimburse the Managing General
            Partner for the Partnership's Administrative Costs; and

      (iv)  it shall not be received for plugged or abandoned wells.

4.04(a)(2)(d). GAS GATHERING. The Managing General Partner, not acting as a
Partner, shall be responsible for gathering and transporting the natural gas
produced by the Partnership to interstate pipeline systems, local distribution
companies, and/or end-users in the area (the "gathering services"). In providing
the gathering services, the Managing General Partner may use the gathering
system owned by Atlas Pipeline Partners as required in the Prospectus, and
gathering systems owned by independent third-parties and/or Affiliates of Atlas
America other than Atlas Pipeline Partners.


                                       31


The Partnership shall pay a gathering fee directly to the Managing General
Partner at competitive rates for the gathering services. The gathering fee paid
by the Partnership to the Managing General Partner may be increased from
time-to-time by the Managing General Partner, in its sole discretion, but may
not increase beyond competitive rates as determined by the Managing General
Partner. Currently, the Managing General Partner has determined that the
competitive rate is an amount equal to 10% of the gross sales price received by
the Partnership for its natural gas in each of its primary or secondary areas as
described in the Prospectus. Gross sales price means the price that is actually
received, adjusted to take into account proceeds received or payments made
pursuant to hedging arrangements. The payment of a competitive fee to the
Managing General Partner for its gathering services shall be subject to the
following conditions:

      (i)   If the Partnership's natural gas production is gathered and
            transported through the gathering system owned by Atlas Pipeline
            Partners, then the Managing General Partner shall apply its
            gathering fee towards the related gathering fee obligation of Atlas
            America, Inc., Resource Energy, Inc., and Viking Resources
            Corporation (the "Atlas Entities") under their agreement with Atlas
            Pipeline Partners as described in the Prospectus.

      (ii)  If a third-party gathering system is used by the Partnership, then
            the Managing General Partner will pay a portion or all of the
            gathering fee it receives from the Partnership to the third-party
            gathering the natural gas. The Managing General Partner may retain
            the excess of any gathering fees it receives from the Partnership
            over the payments it makes to third-party gas gatherers. If the
            third-party's gathering system charges more than an amount equal to
            10% of the gross sales price, then the Managing General Partner's
            gathering fee charged to the Partnership shall be the actual
            transportation and compression fees charged by the third-party
            gathering system with respect to the Partnership's natural gas in
            the area.

      (iii) If both a third-party gathering system and the Atlas Pipeline
            Partners gathering system (or a gas gathering system owned by an
            affiliate of Atlas America other than Atlas Pipeline Partners) are
            used by the Partnership, then the Managing General Partner shall
            receive an amount equal to 10% of the gross sales price plus the
            amount charged by the third-party gathering system. For purposes of
            illustration, but not limitation, the Partnership will deliver
            natural gas produced from certain wells drilled by the Partnership
            in the Upper Devonian Sandstone Reservoirs in the McKean County,
            Pennsylvania area into a gathering system, a segment of which will
            be provided by Atlas Pipeline Partners and a segment of which will
            be provided by a third-party. The third-party shall receive fees of
            $.35 per mcf for transportation and compression which may be
            increased from time-to-time, and the Managing General Partner shall
            receive a gathering fee equal to 10% of the gross sales price.

With respect to the Knox project and natural gas produced from the Mississippian
and Devonian Shale Reservoirs in Anderson, Campbell, Morgan, Roane and Scott
Counties, Tennessee, as discussed in the Prospectus, if the Coalfield Pipeline
does not have sufficient capacity to compress and transport the natural gas
produced from the Partnership's wells as determined by Atlas America, then Atlas
America or an Affiliate other than Atlas Pipeline Partners may construct an
additional gathering system and/or enhancements to the Coalfield Pipeline. On
completion of the construction, Atlas America will transfer its ownership in the
additional gathering system and/or enhancements to the owners of Coalfield
Pipeline, which will then pay Atlas America an amount equal to $.12 per mcf of
natural gas transported through the newly constructed and/or enhanced gathering
system. Coalfield Pipeline will pay this amount of $.12 per mcf to Atlas America
from its gathering and compression fees charged to the Partnership.

4.04(a)(2)(e). DEALER-MANAGER FEE. Subject to ss.3.03(a)(1), the Dealer-Manager
shall receive on each Unit sold to investors:

      (i)   a 2.5% Dealer-Manager fee;

      (ii)  a 7% Sales Commission;

      (iii) a .5% accountable Reimbursement for Permissible Non-Cash
            Compensation; and


                                       32



      (iv)  an up to .5% reimbursement of the Selling Agents' bona fide due
            diligence expenses.

4.04(a)(2)(f). DRILLING AND OPERATING AGREEMENT. The Managing General Partner
and its Affiliates shall receive compensation as set forth in the Drilling and
Operating Agreement.

4.04(a)(2)(g). OTHER TRANSACTIONS. The Managing General Partner and its
Affiliates may enter into transactions pursuant to ss.4.03(d)(7) with the
Partnership and shall be entitled to compensation under that section.

4.04(a)(3). REMOVAL OF MANAGING GENERAL PARTNER.

4.04(a)(3)(a). MAJORITY VOTE REQUIRED TO REMOVE THE MANAGING GENERAL PARTNER.
The Managing General Partner may be removed at any time on 60 days' advance
written notice to the outgoing Managing General Partner by the affirmative vote
of Participants whose Units equal a majority of the total Units.

If the Participants vote to remove the Managing General Partner from the
Partnership, then Participants must elect by an affirmative vote of Participants
whose Units equal a majority of the total Units either to:

      (i)   terminate, dissolve, and wind up the Partnership; or

      (ii)  continue as a successor limited partnership under all the terms of
            this Partnership Agreement as provided in ss.7.01(c).

If the Participants elect to continue as a successor limited partnership, then
the Managing General Partner shall not be removed until a substituted Managing
General Partner has been selected by an affirmative vote of Participants whose
Units equal a majority of the total Units and installed as such.

4.04(a)(3)(b). VALUATION OF MANAGING GENERAL PARTNER'S INTEREST IN THE
PARTNERSHIP. If the Managing General Partner is removed, then its interest in
the Partnership shall be determined by appraisal by a qualified Independent
Expert. The Independent Expert shall be selected by mutual agreement between the
removed Managing General Partner and the incoming Managing General Partner. The
appraisal shall take into account an appropriate discount, to reflect the risk
of recovery of natural gas and oil reserves, but not less than that used to
calculate the presentment price in the most recent presentment offer under
ss.6.03, if any.

The cost of the appraisal shall be borne equally by the removed Managing General
Partner and the Partnership.

4.04(a)(3)(c). INCOMING MANAGING GENERAL PARTNER'S OPTION TO PURCHASE. The
incoming Managing General Partner shall have the option to purchase 20% of the
removed Managing General Partner's interest in the Partnership as Managing
General Partner, and not as a Participant, for the value determined by the
Independent Expert.

4.04(a)(3)(d). METHOD OF PAYMENT. The method of payment for the removed Managing
General Partner's interest must be fair and protect the solvency and liquidity
of the Partnership. The method of payment shall be as follows:

      (i)   when the termination is voluntary, the method of payment shall be a
            non-interest bearing unsecured promissory note with principal
            payable, if at all, from distributions which the Managing General
            Partner otherwise would have received under the Partnership
            Agreement had the Managing General Partner not been terminated; and

      (ii)  when the termination is involuntary, the method of payment shall be
            an interest bearing promissory note coming due in no less than five
            years with equal installments each year. The interest rate shall be
            that charged on comparable loans.

4.04(a)(3)(e). TERMINATION OF CONTRACTS. At the time of its removal, the removed
Managing General Partner shall cause, to the extent it is legally possible, its
successor to be transferred or assigned all its rights, obligations and
interests as Managing General Partner of the Partnership in contracts entered
into by it on behalf of the Partnership. In any event, the removed Managing
General Partner shall cause its rights, obligations and interests as Managing
General Partner of the Partnership in any such contract to terminate at the time
of its removal.

                                       33


Notwithstanding any other provision in this Agreement, the Partnership or the
successor Managing General Partner shall not:

      (i)   be a party to any natural gas supply agreement that the Managing
            General Partner or its Affiliates enters into with a third-party;

      (ii)  have any rights pursuant to such natural gas supply agreement; or

      (iii) receive any interest in the Managing General Partner's and its
            Affiliates' pipeline or gathering system or compression facilities.

4.04(a)(3)(f). THE MANAGING GENERAL PARTNER'S RIGHT TO VOLUNTARILY WITHDRAW. At
any time beginning 10 years after the Offering Termination Date and the
Partnership's primary drilling activities, the Managing General Partner may
voluntarily withdraw as Managing General Partner on giving 120 days' written
notice of withdrawal to the Participants. If the Managing General Partner
withdraws, then the following conditions shall apply:

      (i)   the Managing General Partner's interest in the Partnership shall be
            determined as described in ss.4.04(a)(3)(b) above with respect to
            removal; and

      (ii)  the interest shall be distributed to the Managing General Partner as
            described in ss.4.04(a)(3)(d)(i) above.

Any successor Managing General Partner shall have the option to purchase 20% of
the withdrawing Managing General Partner's interest in the Partnership at the
value determined as described above with respect to removal.

4.04(a)(3)(g). RIGHT OF MANAGING GENERAL PARTNER TO HYPOTHECATE ITS INTERESTS.
The Managing General Partner shall have the authority without the consent of the
Participants and without affecting the allocation of costs and revenues received
or incurred under this Agreement, to hypothecate, pledge, or otherwise encumber,
on any terms it chooses for its own general purposes, either:

      (i)   its Partnership interest; or

      (ii)  an undivided interest in the assets of the Partnership equal to or
            less than its respective interest as Managing General Partner in the
            revenues of the Partnership.

All repayments of these borrowings and costs, interest or other charges related
to the borrowings shall be borne and paid separately by the Managing General
Partner. In no event shall the repayments, costs, interest, or other charges
related to the borrowing be charged to the account of the Participants.

4.04(a)(3)(h). THE MANAGING GENERAL PARTNER'S RIGHT TO WITHDRAW PROPERTY
INTEREST. Subject to a required participation of not less than 1% in the
Partnership as Managing General Partner, the Managing General Partner has the
right to withdraw a property interest held by the Partnership in the form of a
Working Interest in the Partnership's Wells equal to or less than its respective
interest as Managing General Partner in the revenues of the Partnership if:

      (i)   the withdrawal is necessary to satisfy the bona fide request of its
            creditors; or

      (ii)  the withdrawal is approved by Participants whose Units equal a
            majority of the total Units.

If the Managing General Partner withdraws a property interest from the
Partnership as described above, then the Managing General Partner shall:

      (i)   pay the expenses of withdrawing; and

                                       34


      (ii)  fully indemnify the Partnership against any additional expenses
            which may result from a partial withdrawal of its interests,
            including insuring that a greater amount of Direct Costs or
            Administrative Costs is not allocated to the Participants.

4.04(a)(4). REMOVAL OF OPERATOR. The Operator may be removed and a new Operator
may be substituted at any time on 60 days advance written notice to the outgoing
Operator by the Managing General Partner acting on behalf of the Partnership on
the affirmative vote of Participants whose Units equal a majority of the total
Units.

The Operator shall not be removed until a substituted Operator has been selected
by an affirmative vote of Participants whose Units equal a majority of the total
Units and installed as such.

4.05. INDEMNIFICATION AND EXONERATION.

4.05(a)(1). STANDARDS FOR THE MANAGING GENERAL PARTNER NOT INCURRING LIABILITY
TO THE PARTNERSHIP OR PARTICIPANTS. The Managing General Partner, the Operator,
and their Affiliates shall not have any liability whatsoever to the Partnership,
or to any Participant for any loss suffered by the Partnership or Participants
which arises out of any action or inaction of the Managing General Partner, the
Operator, or their Affiliates if:

      (i)   the Managing General Partner, the Operator, and their Affiliates
            determined in good faith that the course of conduct was in the best
            interest of the Partnership;

      (ii)  the Managing General Partner, the Operator, and their Affiliates
            were acting on behalf of, or performing services for, the
            Partnership; and

      (iii) the course of conduct did not constitute negligence or misconduct of
            the Managing General Partner, the Operator, or their Affiliates.

4.05(a)(2). STANDARDS FOR MANAGING GENERAL PARTNER INDEMNIFICATION. The Managing
General Partner, the Operator, and their Affiliates shall be indemnified by the
Partnership against any losses, judgments, liabilities, expenses, and amounts
paid in settlement of any claims sustained by them in connection with the
Partnership, provided that:

      (i)   the Managing General Partner, the Operator, and their Affiliates
            determined in good faith that the course of conduct which caused the
            loss or liability was in the best interest of the Partnership;

      (ii)  the Managing General Partner, the Operator, and their Affiliates
            were acting on behalf of, or performing services for, the
            Partnership; and

      (iii) the course of conduct was not the result of negligence or misconduct
            of the Managing General Partner, the Operator, or their Affiliates.

Provided, however, payments arising from such indemnification or agreement to
hold harmless are recoverable only out of the following:

      (i)   the Partnership's tangible net assets, which include its revenues;
            and

      (ii)  any insurance proceeds from the types of insurance for which the
            Managing General Partner, the Operator and their Affiliates may be
            indemnified under this Agreement.

4.05(a)(3). STANDARDS FOR SECURITIES LAW INDEMNIFICATION. Notwithstanding
anything to the contrary contained in the above, the Managing General Partner,
the Operator, and their Affiliates and any person acting as a broker/dealer
shall not be indemnified for any losses, liabilities or expenses arising from or
out of an alleged violation of federal or state securities laws by such party
unless:

      (i)   there has been a successful adjudication on the merits of each count
            involving alleged securities law violations as to the particular
            indemnitee;

                                       35


      (ii)  the claims have been dismissed with prejudice on the merits by a
            court of competent jurisdiction as to the particular indemnitee; or

      (iii) a court of competent jurisdiction approves a settlement of the
            claims against a particular indemnitee and finds that
            indemnification of the settlement and the related costs should be
            made, and the court considering the request for indemnification has
            been advised of the position of the SEC, the Massachusetts
            Securities Division, and any state securities regulatory authority
            in which plaintiffs claim they were offered or sold Units with
            respect to the issue of indemnification for violation of securities
            laws.

4.05(a)(4). STANDARDS FOR ADVANCEMENT OF FUNDS TO THE MANAGING GENERAL PARTNER
AND INSURANCE. The advancement of Partnership funds to the Managing General
Partner, the Operator, or their Affiliates for legal expenses and other costs
incurred as a result of any legal action for which indemnification is being
sought is permissible only if the Partnership has adequate funds available and
the following conditions are satisfied:

      (i)   the legal action relates to acts or omissions with respect to the
            performance of duties or services on behalf of the Partnership;

      (ii)  the legal action is initiated by a third-party who is not a
            Participant, or the legal action is initiated by a Participant and a
            court of competent jurisdiction specifically approves the
            advancement; and

      (iii) the Managing General Partner or its Affiliates undertake to repay
            the advanced funds to the Partnership, together with the applicable
            legal rate of interest thereon, in cases in which such party is
            found not to be entitled to indemnification.

The Partnership shall not bear the cost of that portion of insurance which
insures the Managing General Partner, the Operator, or their Affiliates for any
liability for which they could not be indemnified pursuant to ss.ss.4.05(a)(1)
and 4.05(a)(2).

4.05(b). LIABILITY OF PARTNERS. Under the Delaware Revised Uniform Limited
Partnership Act, the Investor General Partners are liable jointly and severally
for all liabilities and obligations of the Partnership. Notwithstanding the
foregoing, as among themselves, the Investor General Partners agree that each
shall be solely and individually responsible only for his pro rata share of the
liabilities and obligations of the Partnership based on his respective number of
Units.

In addition, the Managing General Partner agrees to use its corporate assets to
indemnify each of the Investor General Partners against all Partnership related
liabilities which exceed the Investor General Partner's interest in the
undistributed net assets of the Partnership and insurance proceeds, if any.
Further, the Managing General Partner agrees to indemnify each Investor General
Partner against any personal liability as a result of the unauthorized acts of
another Investor General Partner.

If the Managing General Partner provides indemnification, then each Investor
General Partner who has been indemnified shall transfer and subrogate his rights
for contribution from or against any other Investor General Partner to the
Managing General Partner.

4.05(c). ORDER OF PAYMENT OF CLAIMS. Claims shall be paid as follows:

      (i)   first, out of any insurance proceeds;

      (ii)  second, out of Partnership assets and revenues; and

      (iii) last, by the Managing General Partner as provided in
            ss.ss.3.05(b)(2) and (3) and 4.05(b).

No Limited Partner shall be required to reimburse the Managing General Partner,
the Operator, their Affiliates, or the Investor General Partners for any
liability in excess of his agreed Capital Contribution, except:

      (i)   for a liability resulting from the Limited Partner's unauthorized
            participation in Partnership management; or

      (ii)  from some other breach by the Limited Partner of this Agreement.

                                       36


4.05(d). AUTHORIZED TRANSACTIONS ARE NOT DEEMED TO BE A BREACH. No transaction
entered into or action taken by the Partnership, or the Managing General
Partner, the Operator, or their Affiliates, which is authorized by this
Agreement shall be deemed a breach of any obligation owed by the Managing
General Partner, the Operator, or their Affiliates to the Partnership or the
Participants.

4.06. OTHER ACTIVITIES.

4.06(a). THE MANAGING GENERAL PARTNER MAY PURSUE OTHER NATURAL GAS AND OIL
ACTIVITIES FOR ITS OWN ACCOUNT. The Managing General Partner, the Operator, and
their Affiliates are now engaged, and will engage in the future, for their own
account and for the account of others, including other investors, in all aspects
of the natural gas and oil business. This includes without limitation, the
evaluation, acquisition, and sale of producing and nonproducing Leases, and the
exploration for and production of natural gas, oil and other minerals.

The Managing General Partner is required to devote only so much of its time as
is necessary to manage the affairs of the Partnership. Except as expressly
provided to the contrary in this Agreement, and subject to fiduciary duties, the
Managing General Partner, the Operator, and their Affiliates may do the
following:

      (i)   continue their activities, or initiate further such activities,
            individually, jointly with others, or as a part of any other limited
            or general partnership, tax partnership, joint venture, or other
            entity or activity to which they are or may become a party, in any
            locale and in the same fields, areas of operation or prospects in
            which the Partnership may likewise be active;

      (ii)  reserve partial interests in Leases being assigned to the
            Partnership or any other interests not expressly prohibited by this
            Agreement;

      (iii) deal with the Partnership as independent parties or through any
            other entity in which they may be interested;

      (iv)  conduct business with the Partnership as set forth in this
            Agreement; and

      (v)   participate in such other investor operations, as investors or
            otherwise.

The Managing General Partner and its Affiliates shall not be required to permit
the Partnership or the Participants to participate in any of the operations in
which the Managing General Partner and its Affiliates may be interested or share
in any profits or other benefits from the operations. However, except as
otherwise provided in this Agreement, the Managing General Partner and its
Affiliates may pursue business opportunities that are consistent with the
Partnership's investment objectives for their own account only after they have
determined that the opportunity either:

      (i)   cannot be pursued by the Partnership because of insufficient funds;
            or

      (ii)  it is not appropriate for the Partnership under the existing
            circumstances.

4.06(b). MANAGING GENERAL PARTNER MAY MANAGE MULTIPLE PARTNERSHIPS. The Managing
General Partner or its Affiliates may manage multiple Programs simultaneously.

4.06(c). PARTNERSHIP HAS NO INTEREST IN NATURAL GAS CONTRACTS OR PIPELINES AND
GATHERING SYSTEMS. Notwithstanding any other provision in this Agreement, the
Partnership shall not:

      (i)   be a party to any natural gas supply agreement that the Managing
            General Partner, the Operator, or their Affiliates enter into with a
            third-party or have any rights pursuant to such natural gas supply
            agreement; or

      (ii)  receive any interest in the Managing General Partner's, the
            Operator's, and their Affiliates' pipeline or gathering system or
            compression facilities.

                                    ARTICLE V
                      PARTICIPATION IN COSTS AND REVENUES,
                  CAPITAL ACCOUNTS, ELECTIONS AND DISTRIBUTIONS

5.01. PARTICIPATION IN COSTS AND REVENUES. Except as otherwise provided in this
Agreement, costs and revenues shall be charged and credited to the Managing
General Partner and the Participants as set forth in this section and its
subsections.

5.01(a). COSTS. Costs shall be charged as set forth below.

5.01(a)(1). ORGANIZATION AND OFFERING COSTS. Organization and Offering Costs
shall be charged 100% to the Managing General Partner. For purposes of sharing
in revenues under ss.5.01(b)(4), the Managing General Partner shall be credited
with Organization and Offering Costs paid by it and for services provided by it
as Organization Costs up to and including 15% of the Partnership's subscription
proceeds. Any Organization and Offering Costs paid and/or provided in services
by the Managing General Partner in excess of this amount shall not be credited
towards the Managing General Partner's required Capital Contribution or revenue
share set forth in ss.5.01(b)(4). The Managing General Partner's credit for
services provided to the Partnership as Organization Costs shall be determined
based on generally accepted accounting principles.

5.01(a)(2). INTANGIBLE DRILLING COSTS. Ninety percent (90%) of the Partnership's
subscription proceeds received from the Participants shall be used to pay 100%
of the Intangible Drilling Costs.

5.01(a)(3). TANGIBLE COSTS. Ten percent (10%) of the Partnership's subscription
proceeds received from the Participants shall be used by the Partnership to pay
Tangible Costs. All remaining Tangible Costs in excess of an amount equal to 10%
of the Partnership's subscription proceeds shall be charged 100% to the Managing
General Partner.

5.01(a)(4). OPERATING COSTS, DIRECT COSTS, ADMINISTRATIVE COSTS AND ALL OTHER
COSTS. Operating Costs, Direct Costs, Administrative Costs, and all other
Partnership costs not specifically allocated shall be charged to the parties in
the same ratio as the related production revenues are being credited.

5.01(a)(5). ALLOCATION OF INTANGIBLE DRILLING COSTS AND TANGIBLE COSTS AT
PARTNERSHIP CLOSINGS. Intangible Drilling Costs and the Participants' share of
Tangible Costs of a well or wells to be drilled and completed with the proceeds
of a Partnership closing shall be charged 100% to the Participants who are
admitted to the Partnership in that closing and shall not be reallocated to take
into account other Partnership closings.

Although the proceeds of each Partnership closing will be used to pay the costs
of drilling different wells, 90% of each Participant's subscription proceeds
shall be applied to Intangible Drilling Costs and 10% of each Participant's
subscription proceeds shall be applied to Tangible Costs regardless of when he
subscribes.

5.01(a)(6). LEASE COSTS. The Leases shall be contributed to the Partnership by
the Managing General Partner as set forth in ss.4.01(a)(4).

5.01(b). REVENUES. Revenues shall be credited as set forth below.

5.01(b)(1). ALLOCATION OF REVENUES ON DISPOSITION OF PROPERTY. If the parties'
Capital Accounts are adjusted to reflect the simulated depletion of a natural
gas or oil property of the Partnership, then the portion of the total amount
realized by the Partnership on the taxable disposition of the property that
represents recovery of its simulated tax basis in the property shall be
allocated to the parties in the same proportion as the aggregate adjusted tax
basis of the property was allocated to the parties or their predecessors in
interest. If the parties' Capital Accounts are adjusted to reflect the actual
depletion of a natural gas or oil property of the Partnership, then the portion
of the total amount realized by the Partnership on the taxable disposition of
the property that equals the parties' aggregate remaining adjusted tax basis in
the property shall be allocated to the parties in proportion to their respective
remaining adjusted tax bases in the property. Thereafter, any excess shall be
allocated to the Managing General Partner in an amount equal to the difference
between the fair market value of the Lease at the time it was contributed to the
Partnership and its simulated or actual adjusted tax basis at that time.
Finally, any excess shall be credited as provided in ss.5.01(b)(4), below.

                                       38


In the event of a sale of developed natural gas and oil properties with
equipment on the properties, the Managing General Partner may make any
reasonable allocation of proceeds between the equipment and the Leases.

5.01(b)(2). INTEREST. Interest earned on each Participant's subscription
proceeds before the Offering Termination Date under ss.3.05(b)(1) shall be
credited to the accounts of the respective subscribers who paid the subscription
proceeds to the Partnership. The interest shall be paid to the Participant not
later than the Partnership's first cash distribution from operations.

After the Offering Termination Date and until proceeds from the offering are
invested in the Partnership's natural gas and oil operations, any interest
income from temporary investments shall be allocated pro rata to the
Participants providing the subscription proceeds.

All other interest income, including interest earned on the deposit of
production revenues, shall be credited as provided in ss.5.01(b)(4), below.

5.01(b)(3). SALE OR DISPOSITION OF EQUIPMENT. Proceeds from the sale or
disposition of equipment shall be credited to the parties charged with the costs
of the equipment in the ratio in which the costs were charged.

5.01(b)(4). OTHER REVENUES. Subject to ss.5.01(b)(4)(a), the Managing General
Partner and the Participants shall share in all other Partnership revenues in
the same percentage as their respective Capital Contribution bears to the total
Partnership Capital Contributions, except that the Managing General Partner
shall receive an additional 7% of Partnership revenues. However, the Managing
General Partner's total revenue share may not exceed 40% of Partnership
revenues. For example, if the Managing General Partner contributes 25% of the
total Partnership Capital Contributions and the Participants contribute 75% of
the total Partnership Capital Contributions, then the Managing General Partner
shall receive 32% of the Partnership revenues and the Participants shall receive
68% of the Partnership revenues. On the other hand, if the Managing General
Partner contributes 35% of the total Partnership Capital Contributions and the
Participants contribute 65% of the total Partnership Capital Contributions, then
the Managing General Partner shall receive 40% of the Partnership revenues, not
42%, because its revenue share cannot exceed 40% of Partnership revenues, and
the Participants shall receive 60% of Partnership revenues.

5.01(b)(4)(a). SUBORDINATION. The Managing General Partner shall subordinate up
to 50% of its share of Partnership Net Production Revenues to the receipt by
Participants of cash distributions from the Partnership equal to $1,000 per Unit
(which is 10% per Unit) regardless of their actual subscription price of the
Units, in each of the first five 12-month periods. In this regard:

      (i)   the 60-month subordination period shall begin with the first cash
            distribution from operations to the Participants;

      (ii)  subsequent subordination distributions, if any, shall be determined
            and made at the time of each subsequent distribution of revenues to
            the Participants; and

      (iii) the Managing General Partner shall not subordinate more than 50% of
            its share of Partnership Net Production Revenues in any
            subordination period.

The subordination shall be determined by:

      (i)   carrying forward to subsequent 12-month periods the amount, if any,
            by which cumulative cash distributions to Participants, including
            any subordination payments, are less than:

            (a)   $1,000 per Unit (10% per Unit) in the first 12-month period;

            (b)   $2,000 per Unit (20% per Unit) in the second 12-month period;

            (c)   $3,000 per Unit (30% per Unit) in the third 12-month period;
                  or

            (d)   $4,000 per Unit (40% per Unit) in the fourth 12-month period
                  (no carry forward is required if such distributions are less
                  than $5,000 per Unit (50% per Unit) in the fifth 12-month
                  period because the Managing General Partner's subordination
                  obligation terminates on the expiration of the fifth 12-month
                  period); and

                                       39


      (ii)  reimbursing the Managing General Partner for any previous
            subordination payments to the extent cumulative cash distributions
            to Participants, including any subordination payments, would exceed:

            (a)   $1,000 per Unit (10% per Unit) in the first 12-month period;

            (b)   $2,000 per Unit (20% per Unit) in the second 12-month period;

            (c)   $3,000 per Unit (30% per Unit) in the third 12-month period;

            (d)   $4,000 per Unit (40% per Unit) in the fourth 12-month period;
                  or

            (e)   $5,000 per Unit (50% per Unit) in the fifth 12-month period.

The Managing General Partner's subordination obligation shall be further subject
to the following conditions:

      (i)   the subordination obligation may be prorated in the Managing General
            Partner's discretion (e.g. in the case of a monthly distribution,
            the Managing General Partner will not have any subordination
            obligation if the distributions to Participants equal $83.33 per
            Unit (8.333% of $1,000 per Unit per year) or more assuming there is
            no subordination owed for any preceding period);

      (ii)  the Managing General Partner shall not be required to return
            Partnership distributions previously received by it, even though a
            subordination obligation arises after the distributions;

      (iii) subject to the foregoing provisions of this section, only
            Partnership revenues in the current distribution period shall be
            debited or credited to the Managing General Partner as may be
            necessary to provide, to the extent possible, subordination
            distributions to the Participants and reimbursements to the Managing
            General Partner;

      (iv)  no subordination payments to the Participants or reimbursements to
            the Managing General Partner shall be made after the expiration of
            the fifth 12-month subordination period; and

      (v)   subordination payments to the Participants shall be subject to any
            lien or priority required by the Managing General Partner's lenders
            pursuant to agreements previously entered into or subsequently
            entered into or renewed by the Managing General Partner.

5.01(b)(5). COMMINGLING OF REVENUES FROM ALL PARTNERSHIP WELLS. The revenues
from all Partnership wells will be commingled, so regardless of when a
Participant subscribes he will share in the revenues from all wells on the same
basis as the other Participants.

5.01(c). ALLOCATIONS.

5.01(c)(1). ALLOCATIONS AMONG PARTICIPANTS. Except as provided otherwise in this
Agreement, costs (other than Intangible Drilling Costs and Tangible Costs) and
revenues charged or credited to the Participants as a group, which includes all
revenue credited to the Participants under ss.5.01(b)(4), shall be allocated
among the Participants, including the Managing General Partner to the extent of
any optional subscription under ss.3.03(b)(2), in the ratio of their respective
Units based on $10,000 per Unit regardless of the actual subscription price for
a Participant's Units.

Intangible Drilling Costs and Tangible Costs charged to the Participants as a
group shall be allocated among the Participants, including the Managing General
Partner to the extent of any optional subscription under ss.3.03(b)(2), in the
ratio of the subscription price designated on their respective Subscription
Agreements rather than the number of their respective Units.

                                       40


5.01(c)(2). COSTS AND REVENUES NOT DIRECTLY ALLOCABLE TO A PARTNERSHIP WELL.
Costs and revenues not directly allocable to a particular Partnership Well or
additional operation shall be allocated among the Partnership Wells or
additional operations in any manner the Managing General Partner in its
reasonable discretion, shall select, and shall then be charged or credited in
the same manner as costs or revenues directly applicable to the Partnership Well
or additional operation are being charged or credited.

5.01(c)(3). MANAGING GENERAL PARTNER'S DISCRETION IN MAKING ALLOCATIONS FOR
FEDERAL INCOME TAX PURPOSES. In determining the proper method of allocating
charges or credits among the parties, allocating any item of income, gain, loss,
deduction or credit which is the result of new laws or new IRS or judicial
interpretations of existing law, or which is not otherwise specifically
allocated in this Agreement or is clearly inconsistent with a party's economic
interest in the Partnership, or making any other allocations under this
Agreement, the Managing General Partner may adopt any method of allocation which
it, in its reasonable discretion, selects in its sole discretion, after
consultation with the Partnership's legal counsel or accountants. Any new
allocation provisions shall be made in a manner that is consistent with the
parties' economic interests in the Partnership and which would result in the
most favorable aggregate consequences to the Participants as nearly as possible
consistent with the original allocations described in this Agreement.

5.02. CAPITAL ACCOUNTS AND ALLOCATIONS THERETO.

5.02(a). CAPITAL ACCOUNTS FOR EACH PARTY TO THIS AGREEMENT. A single, separate
Capital Account shall be established for each party, regardless of the number of
interests owned by the party, the class of the interests and the time or manner
in which the interests were acquired.

5.02(b). CHARGES AND CREDITS.

5.02(b)(1). GENERAL STANDARD. Except as otherwise provided in this Agreement,
the Capital Account of each party shall be determined and maintained in
accordance with Treas. Reg. ss.1.704-l(b)(2)(iv) and shall be increased by:

      (i)   the amount of money contributed by him to the Partnership;

      (ii)  the fair market value of property contributed by him, without regard
            to ss.7701(g) of the Code, to the Partnership, net of liabilities
            secured by the contributed property that the Partnership is
            considered to assume or take subject to under ss.752 of the Code;
            and

      (iii) allocations to him of Partnership income and gain, or items thereof,
            including income and gain exempt from tax and income and gain
            described in Treas. Reg. ss.1.704-l(b)(2)(iv)(g), but excluding
            income and gain described in Treas. Reg. ss.1.704-l(b)(4)(i);

and shall be decreased by:

      (iv)  the amount of money distributed to him by the Partnership;

      (v)   the fair market value of property distributed to him, without regard
            to ss.7701(g) of the Code, by the Partnership, net of liabilities
            secured by the distributed property that he is considered to assume
            or take subject to under ss.752 of the Code;

      (vi)  allocations to him of Partnership expenditures described in
            ss.705(a)(2)(B) of the Code; and

      (vii) allocations to him of Partnership loss and deduction, or items
            thereof, including loss and deduction described in Treas. Reg.
            ss.1.704-l(b)(2)(iv)(g), but excluding items described in (vi)
            above, and loss or deduction described in Treas. Reg.
            ss.1.704-l(b)(4)(i) or (iii).

5.02(b)(2). EXCEPTION. If Treas. Reg. ss.1.704-l(b)(2)(iv) fails to provide
guidance, Capital Account adjustments shall be made in a manner that:

                                       41


      (i)   maintains equality between the aggregate governing Capital Accounts
            of the parties and the amount of Partnership capital reflected on
            the Partnership's balance sheet, as computed for book purposes;

      (ii)  is consistent with the underlying economic arrangement of the
            parties; and

      (iii) is based, wherever practicable, on federal tax accounting
            principles.

5.02(c). PAYMENTS TO THE MANAGING GENERAL PARTNER. The Capital Account of the
Managing General Partner shall be reduced by payments to it pursuant to
ss.4.04(a)(2) only to the extent of the Managing General Partner's distributive
share of any Partnership deduction, loss, or other downward Capital Account
adjustment resulting from the payments. Also, in the event, and to the extent,
that the Managing General Partner is treated under the Code as having been
transferred an interest in the Partnership in connection with the performance of
services for the Partnership (whether before or after the formation of the
Partnership):

      (i)   any resulting compensation income shall be allocated 100% to the
            Managing General Partner;

      (ii)  any associated increase in Capital Accounts shall be credited 100%
            to the Managing General Partner; and

      (iii) any associated deduction to which the Partnership is entitled shall
            be allocated 100% to the Managing General Partner.

5.02(d). DISCRETION OF MANAGING GENERAL PARTNER IN THE METHOD OF MAINTAINING
CAPITAL ACCOUNTS. Notwithstanding any other provisions of this Agreement, the
method of maintaining Capital Accounts may be changed from time to time, in the
discretion of the Managing General Partner, to take into consideration ss.704
and other provisions of the Code and the related rules, regulations and
interpretations as may exist from time to time.

5.02(e). REVALUATIONS OF PROPERTY. In the discretion of the Managing General
Partner the Capital Accounts of the parties may be increased or decreased to
reflect a revaluation of Partnership property, including intangible assets such
as goodwill, on a property-by-property basis except as otherwise permitted under
ss.704(c) of the Code and the regulations thereunder, on the Partnership's
books, in accordance with Treas. Reg. ss.1.704-l(b)(2)(iv)(f).

5.02(f). AMOUNT OF BOOK ITEMS. In cases where ss.704(c) of the Code or
ss.5.02(e) applies, Capital Accounts shall be adjusted in accordance with Treas.
Reg. ss.1.704-l(b)(2)(iv)(g) for allocations of depreciation, depletion,
amortization and gain and loss, as computed for book purposes, with respect to
the property.

5.03. ALLOCATION OF INCOME, DEDUCTIONS AND CREDITS.

5.03(a). IN GENERAL.

5.03(a)(1). DEDUCTIONS ARE ALLOCATED TO PARTY CHARGED WITH EXPENDITURE. To the
extent permitted by law and except as otherwise provided in this Agreement, all
deductions and credits, including, but not limited to, intangible drilling and
development costs and depreciation, shall be allocated to the party who has been
charged with the expenditure giving rise to the deductions and credits; and to
the extent permitted by law, these parties shall be entitled to the deductions
and credits in computing taxable income or tax liabilities to the exclusion of
any other party. Also, any Partnership deductions that would be nonrecourse
deductions if they were not attributable to a loan made or guaranteed by the
Managing General Partner or its Affiliates shall be allocated to the Managing
General Partner to the extent required by law.

5.03(a)(2). INCOME AND GAIN ALLOCATED IN ACCORDANCE WITH REVENUES. Except as
otherwise provided in this Agreement, all items of income and gain, including
gain on disposition of assets, shall be allocated in accordance with the related
revenue allocations set forth in ss.5.01(b) and its subsections.

5.03(b). TAX BASIS OF EACH PROPERTY. Subject to ss.704(c) of the Code, the tax
basis of each oil and gas property for computation of cost depletion and gain or
loss on disposition shall be allocated and reallocated when necessary based on
the capital interest in the Partnership as to the property and the capital
interest in the Partnership for this purpose as to each property shall be
considered to be owned by the parties in the ratio in which the expenditure
giving rise to the tax basis of the property has been charged as of the end of
the year.

                                       42


5.03(c). GAIN OR LOSS ON OIL AND GAS PROPERTIES. Each party shall separately
compute its gain or loss on the disposition of each natural gas and oil property
in accordance with the provisions of ss.613A(c)(7)(D) of the Code, and the
calculation of the gain or loss shall consider the party's adjusted basis in his
property interest computed as provided in ss.5.03(b) and the party's allocable
share of the amount realized from the disposition of the property.

5.03(d). GAIN ON DEPRECIABLE PROPERTY. Gain from each sale or other disposition
of depreciable property shall be allocated to each party whose share of the
proceeds from the sale or other disposition exceeds its contribution to the
adjusted basis of the property in the ratio that the excess bears to the sum of
the excesses of all parties having an excess.

5.03(e). LOSS ON DEPRECIABLE PROPERTY. Loss from each sale, abandonment or other
disposition of depreciable property shall be allocated to each party whose
contribution to the adjusted basis of the property exceeds its share of the
proceeds from the sale, abandonment or other disposition in the proportion that
the excess bears to the sum of the excesses of all parties having an excess.

5.03(f). ALLOCATION IF RECAPTURE TREATED AS ORDINARY INCOME. Any recapture
treated as an increase in ordinary income by reason of ss.ss.1245, 1250, or 1254
of the Code shall be allocated to the parties in the amounts in which the
recaptured items were previously allocated to them; provided that to the extent
recapture allocated to any party is in excess of the party's gain from the
disposition of the property, the excess shall be allocated to the other parties
but only to the extent of the other parties' gain from the disposition of the
property.

5.03(g). TAX CREDITS. If a Partnership expenditure, whether or not deductible,
that gives rise to a tax credit in a Partnership taxable year also gives rise to
valid allocations of Partnership loss or deduction, or other downward Capital
Account adjustments, for the year, then the parties' interests in the
Partnership with respect to the credit, or the cost giving rise thereto, shall
be in the same proportion as the parties' respective distributive shares of the
loss or deduction, and adjustments. If Partnership receipts, whether or not
taxable, that give rise to a tax credit, including a marginal well production
credit under ss.45I of the Code, in a Partnership taxable year also give rise to
valid allocations of Partnership income or gain, or other upward Capital Account
adjustments, for the year, then the parties' interests in the Partnership with
respect to the credit, or the Partnership's receipts or production of natural
gas and oil production giving rise thereto, shall be in the same proportion as
the parties' respective shares of the Partnership's production revenues from the
sales of its natural gas and oil production as provided in ss.5.01(b)(4).

5.03(h). DEFICIT CAPITAL ACCOUNTS AND QUALIFIED INCOME OFFSET. Notwithstanding
any provisions of this Agreement to the contrary, an allocation of loss or
deduction which would result in a party having a deficit Capital Account balance
as of the end of the taxable year to which the allocation relates, if charged to
the party, to the extent the Participant is not required to restore the deficit
to the Partnership, taking into account:

      (i)   adjustments that, as of the end of the year, reasonably are expected
            to be made to the party's Capital Account for depletion allowances
            with respect to the Partnership's natural gas and oil properties;

      (ii)  allocations of loss and deduction that, as of the end of the year,
            reasonably are expected to be made to the party under
            ss.ss.704(e)(2) and 706(d) of the Code and Treas. Reg.
            ss.1.751-1(b)(2)(ii); and

      (iii) distributions that, as of the end of the year, reasonably are
            expected to be made to the party to the extent they exceed
            offsetting increases to the party's Capital Account, assuming for
            this purpose that the fair market value of Partnership property
            equals its adjusted tax basis, that reasonably are expected to occur
            during or prior to the Partnership taxable years in which the
            distributions reasonably are expected to be made;

shall be charged to the Managing General Partner. Further, the Managing General
Partner shall be credited with an additional amount of Partnership income or
gain equal to the amount of the loss or deduction as quickly as possible to the
extent such chargeback does not cause or increase deficit balances in the
parties' Capital Accounts which are not required to be restored to the
Partnership.

                                       43


Notwithstanding any provisions of this Agreement to the contrary, if a party
unexpectedly receives an adjustment, allocation, or distribution described in
(i), (ii), or (iii) above, or any other distribution, which causes or increases
a deficit balance in the party's Capital Account which is not required to be
restored to the Partnership, the party shall be allocated items of income and
gain, consisting of a pro rata portion of each item of Partnership income,
including gross income, and gain for the year, in an amount and manner
sufficient to eliminate the deficit balance as quickly as possible.

5.03(i). MINIMUM GAIN CHARGEBACK. To the extent there is a net decrease during a
Partnership taxable year in the minimum gain attributable to a Partner
nonrecourse debt, then any Partner with a share of the minimum gain attributable
to the debt at the beginning of the year shall be allocated items of Partnership
income and gain in accordance with Treas. Reg. ss.1.704-2(i).

5.03(j). PARTNERS' ALLOCABLE SHARES. Except as otherwise provided in this
Agreement, each party's allocable share of Partnership income, gain, loss,
deductions and credits shall be determined by the use of any method prescribed
or permitted by the Secretary of the Treasury by regulations or other guidelines
and selected by the Managing General Partner which takes into account the
varying interests of the parties in the Partnership during the taxable year. In
the absence of such regulations or guidelines, except as otherwise provided in
this Agreement, the allocable share shall be based on actual income, gain, loss,
deductions and credits economically accrued each day during the taxable year in
proportion to each party's varying interest in the Partnership on each day
during the taxable year.

5.03(k). CONTINGENT INCOME. Subject to ss.5.04(d), if it is determined that any
taxable income results to any party by reason of its entitlement to a share of
capital of the Partnership, or a share of profits or revenues of the Partnership
before the profit or revenue has been realized by the Partnership, the resulting
deduction as well as any resulting gain, shall not enter into Partnership net
income or loss, but shall be separately allocated to that party.

5.04. ELECTIONS.

5.04(a). ELECTION TO DEDUCT INTANGIBLE COSTS. The Partnership's federal income
tax return shall be made in accordance with an election under the option granted
by the Code to deduct intangible drilling and development costs.

5.04(b). NO ELECTION OUT OF SUBCHAPTER K. No election shall be made by the
Partnership, any Partner, or the Operator for the Partnership to be excluded
from the application of the partnership provisions of the Code, including
Subchapter K of Chapter 1 of Subtitle A of the Code.

5.04(c). SS.754 ELECTION. In the event of the transfer of an interest in the
Partnership, or on the death of an individual party hereto, or in the event of
the distribution of property to any party, the Managing General Partner may
choose for the Partnership to file an election in accordance with the applicable
Treasury Regulations to cause the basis of the Partnership's assets to be
adjusted for federal income tax purposes as provided by ss.ss.734 and 743 of the
Code.

5.04(d). SS.83 ELECTION. The Partnership, the Managing General Partner and each
Participant hereby agree to be legally bound by the provisions of this
ss.5.04(d) and further agree that, in the Managing General Partner's sole
discretion, the Partnership and all of its Partners may elect a safe harbor
under which the fair market value of a Partnership interest that is transferred
in connection with the performance of services is treated as being equal to the
liquidation value of that interest for transfers on or after the date final
regulations providing the safe harbor are published in the Federal Register. If
the Managing General Partner determines that the Partnership and all of its
Partners will elect the safe harbor, which determination may be made solely in
the best interests of the Managing General Partner, the Partnership, the
Managing General Partner and each Participant further agree that:

      (i)   the Partnership shall be authorized and directed to elect the safe
            harbor;

      (ii)  the Partnership and each of its Partners (including any Person to
            whom a Partnership interest is transferred in connection with the
            performance of services) shall comply with all requirements of the
            safe harbor with respect to all Partnership interests transferred in
            connection with the performance of services while the election
            remains effective; and

      (iii) the Managing General Partner, in its sole discretion, may cause the
            Partnership to terminate the safe harbor election, which
            determination may be made in the sole interests of the Managing
            General Partner.

5.05. DISTRIBUTIONS.

5.05(a). IN GENERAL.

5.05(a)(1). MONTHLY REVIEW OF ACCOUNTS. The Managing General Partner shall
review the accounts of the Partnership at least monthly to determine whether
cash distributions are appropriate and the amount to be distributed, if any.

5.05(a)(2). DISTRIBUTIONS. The Partnership shall distribute funds to the
Managing General Partner and the Participants allocated to their accounts which
the Managing General Partner deems unnecessary to retain by the Partnership.

5.05(a)(3). NO BORROWINGS. In no event, however, shall funds be advanced or
borrowed for distributions if the amount of the distributions would exceed the
Partnership's accrued and received revenues for the previous four quarters, less
paid and accrued Operating Costs with respect to the revenues. The determination
of revenues and costs shall be made in accordance with generally accepted
accounting principles, consistently applied.

5.05(a)(4). DISTRIBUTIONS TO THE MANAGING GENERAL PARTNER. Cash distributions
from the Partnership to the Managing General Partner shall only be made as
follows:

      (i)   in conjunction with distributions to Participants; and

      (ii)  out of funds properly allocated to the Managing General Partner's
            account.

5.05(a)(5). RESERVE. At any time after one year from the date each Partnership
Well is placed into production, the Managing General Partner shall have the
right to deduct each month from the Partnership's proceeds of the sale of the
production from the well up to $200 for the purpose of establishing a fund to
cover the estimated costs of plugging and abandoning the well. All of these
funds shall be deposited in a separate interest bearing account for the benefit
of the Partnership, and the total amount so retained and deposited shall not
exceed the Managing General Partner's reasonable estimate of the costs.

5.05(b). DISTRIBUTION OF UNCOMMITTED SUBSCRIPTION PROCEEDS. Any net subscription
proceeds not expended or committed for expenditure, as evidenced by a written
agreement, by the Partnership within 12 months of the Offering Termination Date,
except necessary operating capital, shall be distributed to the Participants in
the ratio that the subscription price designated on each Participant's
Subscription Agreement bears to the total subscription prices designated on all
of the Participants' Subscription Agreements, as a return of capital. The
Managing General Partner shall reimburse the Participants for the selling or
other offering expenses, if any, allocable to the return of capital.

For purposes of this subsection, "committed for expenditure" shall mean
contracted for, actually earmarked for or allocated by the Managing General
Partner to the Partnership's drilling operations, and "necessary operating
capital" shall mean those funds which, in the opinion of the Managing General
Partner, should remain on hand to assure continuing operation of the
Partnership.

5.05(c). DISTRIBUTIONS ON WINDING UP. On the winding up of the Partnership
distributions shall be made as provided in ss.7.02.

5.05(d). INTEREST AND RETURN OF CAPITAL. No party shall under any circumstances
be entitled to any interest on amounts retained by the Partnership. Each
Participant shall look only to his share of distributions, if any, from the
Partnership for a return of his Capital Contribution.

                                       45


                                   ARTICLE VI
                                TRANSFER OF UNITS

6.01. TRANSFERABILITY OF UNITS. A Participant's transfer of a portion or all his
Units, or any interest in his Units, is subject to all provisions of this
Article VI. For purposes of this Article VI, the term "transfer" shall include
any sale, exchange, gift, assignment, pledge, mortgage, hypothecation,
redemption or other form of transfer of a Unit, or any interest in a Unit, by a
Participant (which may include the Managing General Partner or its Affiliates,
if they purchase Units) or by operation of law, including any transfers of Units
which a Participant presents to the Managing General Partner for purchase under
ss.6.03.

6.01(a). RIGHTS OF ASSIGNEE. Unless a transferee of a Participant's Unit becomes
a substitute Participant with respect to that Unit in accordance with the
provisions of ss.6.02(a)(3)(a), he shall not be entitled to any of the rights
granted to a Participant under this Agreement, other than the right to receive
all or part of the share of the profits, losses, income, gains, deductions,
credits and depletion allowances, or items thereof, and cash distributions or
returns of capital to which his transferor would otherwise be entitled under
this Agreement.

6.01(b). CONVERSION OF INVESTOR GENERAL PARTNER UNITS TO LIMITED PARTNER UNITS.

6.01(b)(1). AUTOMATIC CONVERSION. After all of the Partnership Wells have been
drilled and completed, as determined by the Managing General Partner, the
Managing General Partner shall file an amended certificate of limited
partnership with the Secretary of State of the State of Delaware for the purpose
of converting the Investor General Partner Units to Limited Partner Units.

6.01(b)(2). INVESTOR GENERAL PARTNERS SHALL HAVE CONTINGENT LIABILITY. On
conversion the Investor General Partners shall be Limited Partners entitled to
limited liability; however, they shall remain liable to the Partnership for any
additional Capital Contribution required for their proportionate share of any
Partnership obligation or liability arising before the conversion of their Units
as provided in ss.3.05(b)(2).

6.01(b)(3). CONVERSION SHALL NOT AFFECT ALLOCATIONS. The conversion shall not
affect the allocation to any Participant of any item of Partnership income,
gain, loss, deduction or credit or other item of special tax significance other
than Partnership liabilities, if any. Further, the conversion shall not affect
any Participant's interest in the Partnership's natural gas and oil properties
and unrealized receivables.

6.01(b)(4). RIGHT TO CONVERT IF REDUCTION OF INSURANCE. Notwithstanding the
foregoing, the Managing General Partner shall notify all Participants at least
30 days before the effective date of any adverse material change in the
Partnership's insurance coverage. If the insurance coverage is to be materially
reduced, then the Investor General Partners shall have the right to convert
their Units into Limited Partner Units before the reduction by giving written
notice to the Managing General Partner.

6.02. SPECIAL RESTRICTIONS ON TRANSFERS OF UNITS BY PARTICIPANTS.

6.02(a). IN GENERAL. Transfers of Units by Participants are subject to the
following general conditions:

      (i)   except as provided by operation of law:

            (a)   only whole Units may be transferred unless the Participant
                  owns less than a whole Unit, in which case his entire
                  fractional interest must be transferred; and

            (b)   Units may not be transferred to a person who is under the age
                  of 18 or incompetent (unless an attorney-in-fact, guardian,
                  custodian or conservator has been appointed to handle the
                  affairs of that person) without the Managing General Partner's
                  consent;

      (ii)  the costs and expenses associated with the transfer must be paid by
            the assignor Participant;

      (iii) the transfer documents must be in a form satisfactory to the
            Managing General Partner; and

                                       46


      (iv)  the terms of the transfer must not contravene those of this
            Agreement.

Transfers of Units by Participants are subject to the following additional
restrictions set forth in ss.ss.6.02(a)(1) and 6.02(a)(2).

6.02(a)(1). TAX LAW RESTRICTIONS. Subject to transfers permitted by ss.6.03 and
transfers by operation of law, no transfer of a Unit by a Participant shall be
made which, in the opinion of counsel to the Partnership, would result in the
Partnership being either:

      (i)   terminated for tax purposes under ss.708 of the Code; or

      (ii)  treated as a "publicly-traded" partnership for purposes of ss.469(k)
            of the Code.

6.02(a)(2). SECURITIES LAWS RESTRICTION. Subject to transfers permitted by
ss.6.03 and transfers by operation of law, no Unit shall be transferred by a
Participant unless there is either:

      (i)   an effective registration of the Unit under the Securities Act of
            1933, as amended, and qualification under applicable state
            securities laws; or

      (ii)  an opinion of counsel acceptable to the Managing General Partner
            that the registration and qualification of the Unit is not required.

Transfers of Units by Participants are also subject to any conditions contained
in the Subscription Agreement and Exhibit (B) to the Prospectus.

6.02(a)(3). SUBSTITUTE PARTICIPANT.

6.02(a)(3)(a). PROCEDURE TO BECOME SUBSTITUTE PARTICIPANT. Subject to
ss.ss.6.02(a)(1) and 6.02(a)(2), a transferee of a Participant's Unit shall
become a substitute Participant entitled to all the rights of a Participant if,
and only if:

      (i)   the transferor gives the transferee the right;

      (ii)  the transferee pays to the Partnership all costs and expenses
            incurred in connection with the substitution; and

      (iii) the transferee executes and delivers the instruments necessary to
            establish that a legal transfer has taken place and to confirm the
            agreement of the transferee to be bound by all of the terms of this
            Agreement, in a form acceptable to the Managing General Partner.

6.02(a)(3)(b). RIGHTS OF SUBSTITUTE PARTICIPANT. A substitute Participant is
entitled to all of the rights attributable to full ownership of the assigned
Units including the right to vote.

6.02(b). EFFECT OF TRANSFER.

6.02(b)(1). AMENDMENT OF RECORDS. The Partnership shall amend its records at
least once each calendar quarter to effect the substitution of substitute
Participants.

Any transfer of a Unit by a Participant which is permitted under this Article
VI, when the transferee does not become a substitute Participant, shall be
effective as follows:

      (i)   midnight of the last day of the calendar month in which it is made;
            or

      (ii)  at the Managing General Partner's election, 7:00 A.M. of the
            following day.

6.02(b)(2). A TRANSFER OF UNITS DOES NOT RELIEVE THE TRANSFEROR OF CERTAIN
COSTS. No transfer of a Unit by a Participant, including a transfer of less than
all of a Participant's Units or the transfer of a Participant's Units to more
than one party, shall relieve the transferor of its responsibility for its
proportionate part of any expenses, obligations and liabilities under this
Agreement related to the Units so transferred, whether arising before or after
the transfer.

                                       47


6.02(b)(3). A TRANSFER OF UNITS DOES NOT REQUIRE A PARTNERSHIP ACCOUNTING. No
transfer of a Unit by a Participant shall require an accounting by the Managing
General Partner. Also, no transfer of a Unit shall grant rights under this
Agreement, including the exercise of any elections, as between the transferring
Participant and the Partnership, the Managing General Partner and the remaining
Participants to more than one Person unanimously designated by the transferee(s)
of the Unit, and, if he has retained an interest in the transferred Unit, the
transferor of the Unit.

6.02(b)(4). REQUIRED NOTICE TO MANAGING GENERAL PARTNER OF TRANSFER OF UNITS.
Until the Managing General Partner receives from the transferring Participant a
written notice in a form acceptable to the Managing General Partner which
designates the transferee(s) of a Unit, the Managing General Partner shall
continue to account only to the Person to whom it was furnishing notices
pursuant to ss.8.01 and its subsections before the purported transfer of the
Unit. This party shall continue to exercise all rights applicable to the Units
previously owned by the transferor.

6.03. PRESENTMENT.

6.03(a). IN GENERAL. Participants shall have the right to present their Units to
the Managing General Partner for purchase subject to the conditions and
limitations set forth in this ss.6.03. A Participant, however, is not obligated
to present his Units for purchase.

The Managing General Partner shall not be obligated to purchase more than 5% of
the Units in any calendar year and this 5% limit may not be waived. The Managing
General Partner shall not purchase less than one Unit unless the lesser amount
represents the Participant's entire interest in the Partnership, however, the
Managing General Partner may waive this limitation.

A Participant may present his Units in writing to the Managing General Partner
every year beginning with the fifth calendar year after the Offering Termination
Date subject to the following conditions:

      (i)   the presentment must be made within 120 days of the reserve report
            set forth in ss.4.03(b)(3);

      (ii)  in accordance with Treas. Reg. ss.1.7704-1(f), the purchase may not
            be made until at least 60 calendar days after the Participant
            notifies the Partnership in writing of the Participant's intention
            to exercise the presentment right; and

      (iii) the purchase shall not be considered effective until the presentment
            price has been paid in cash to the Participant.

6.03(b). REQUIREMENT FOR INDEPENDENT PETROLEUM CONSULTANT. The amount of the
presentment price attributable to Partnership reserves shall be determined based
on the last reserve report of the Partnership prepared by the Managing General
Partner and reviewed by an Independent Expert. The Managing General Partner
shall estimate the present worth of future net revenues attributable to the
Partnership's interest in the Proved Reserves as described in ss.4.03(b)(3)(ii).
The calculation of the presentment price shall be as set forth in ss.6.03(c).

6.03(c). CALCULATION OF PRESENTMENT PRICE. The presentment price shall be based
on the Participant's share of the net assets and liabilities of the Partnership
and allocated pro rata to each Participant in the ratio that his number of Units
bears to the total number of Units. The presentment price shall include the sum
of the following Partnership items:

      (i)   an amount based on 70% of the present worth of future net revenues
            from the Proved Reserves determined as described in ss.6.03(b);

      (ii)  cash on hand;

      (iii) prepaid expenses and accounts receivable less a reasonable amount
            for doubtful accounts; and

                                       48


      (iv)  the estimated market value of all assets, not separately specified
            above, determined in accordance with standard industry valuation
            procedures.

There shall be deducted from the foregoing sum the following items:

      (i)   an amount equal to all debts, obligations, and other liabilities,
            including accrued expenses; and

      (ii)  any distributions made to the Participants between the date of the
            request and the actual payment. However, if any cash distributed was
            derived from the sale after the presentment request of natural gas,
            oil or other mineral production, or of a producing property owned by
            the Partnership, for purposes of determining the reduction of the
            presentment price, the distributions shall be discounted at the same
            rate used to take into account the risk factors employed to
            determine the present worth of the Partnership's Proved Reserves.

6.03(d). FURTHER ADJUSTMENT MAY BE ALLOWED. The presentment price may be further
adjusted by the Managing General Partner for estimated changes therein from the
date of the report to the date of payment of the presentment price to the
Participants because of the following:

      (i)   the production or sales of, or additions to, reserves and lease and
            well equipment, sale or abandonment of Leases, and similar matters
            occurring before the request for purchase; and

      (ii)  any of the following occurring before payment of the presentment
            price to the selling Participants:

            (a)   changes in well performance;

            (b)   increases or decreases in the market price of natural gas, oil
                  or other minerals;

            (c)   revision of regulations relating to the importing of
                  hydrocarbons;

            (d)   changes in income, ad valorem, and other tax laws such as
                  material variations in the provisions for depletion; and

            (e)   similar matters.

6.03(e). SELECTION BY LOT. If less than all Units presented at any time are to
be purchased, then the Participants whose Units are to be purchased will be
selected by lot.

The Managing General Partner's obligation to purchase Units presented may be
discharged for its benefit by a third-party or an Affiliate. The Units of the
selling Participant will be transferred to the party who pays for it. A selling
Participant will be required to deliver an executed assignment of his Units, in
a form satisfactory to the Managing General Partner, together with any other
documentation as the Managing General Partner may reasonably request.

6.03(f). NO OBLIGATION OF THE MANAGING GENERAL PARTNER TO ESTABLISH A RESERVE.
The Managing General Partner shall have no obligation to establish any reserve
to satisfy the presentment obligations under this section.

6.03(g). SUSPENSION OF PRESENTMENT FEATURE. The Managing General Partner may
suspend this presentment feature by so notifying Participants at any time if it:

      (i)   does not have sufficient cash flow; or

      (ii)  is unable to borrow funds for this purpose on terms it deems
            reasonable.

In addition, the presentment feature may be conditioned, in the Managing General
Partner's sole discretion, on the Managing General Partner's receipt of an
opinion of counsel that the transfers will not cause the Partnership to be
treated as a "publicly traded partnership" under the Code.

The Managing General Partner shall hold the purchased Units for its own account
and not for resale.

                                       49

partnership and the parties to the successor limited partnership.

7.02. DISSOLUTION AND WINDING UP.

7.02(a). FINAL TERMINATING EVENT. On the occurrence of a Final Terminating Event
the affairs of the Partnership shall be wound up and there shall be distributed
to each of the parties its Distribution Interest in the remaining Partnership

7.02(b). TIME OF LIQUIDATING DISTRIBUTION. To the extent practicable and in
accordance with sound business practices in the judgment of the Managing General
Partner, liquidating distributions shall be made by:

      (i)   the end of the taxable year in which liquidation occurs, determined
            without regard to ss.706(c)(2)(A) of the Code; or

      (ii)  if later, within 90 days after the date of the liquidation.

Notwithstanding, the following amounts are not required to be distributed within
the foregoing time periods so long as the withheld amounts are distributed as

            the Partnership; and

      (ii)  installment obligations owed to the Partnership.

7.02(c). IN-KIND DISTRIBUTIONS. The Managing General Partner shall not be
obligated to offer in-kind property distributions to the Participants, but may
do so, in its discretion. Any in-kind property distributions to the Participants
shall be made to a liquidating trust or similar entity for the benefit of the
Participants, unless at the time of the distribution:

      (i)   the Managing General Partner offers the individual Participants the
            election of receiving in-kind property distributions and the
            Participants accept the offer after being advised of the risks
            associated with direct ownership; or

      (ii)  there are alternative arrangements in place which assure the
            Participants that they will not, at any time, be responsible for the
            operation or disposition of Partnership properties.

                                       50


If the Managing General Partner has not received a Participant's consent within
30 days after the Managing General Partner mailed the request for consent, then
it shall be presumed that the Participant has refused his consent.

7.02(d). SALE IF NO CONSENT. Any Partnership asset which would otherwise be
distributed in-kind to a Participant, except for the failure or refusal of the
Participant to give his written consent to the distribution, may instead be sold
by the Managing General Partner at the best price reasonably obtainable from an
independent third-party, who is not an Affiliate of the Managing General Partner
or to itself or its Affiliates, including an Affiliated Income Program, at fair
market value as determined by an Independent Expert selected by the Managing
General Partner.

General Partner.

Any transfer of Units under this Agreement shall not increase the duty to give

INITIALS          INITIALS
- --------          --------
                              

_____             _____             I have received the Prospectus.

_____             _____             I (other than if I am a Minnesota or Maine resident) recognize and understand that
                                    before this offering there has been no public market for the Units and it is unlikely
                                    that after the offering there will be any such market, the transferability of the
                                    Units is restricted, and in case of emergency or other change in circumstances I
                                    cannot expect to be able to readily liquidate my investment in the Units.

_____             _____             I am purchasing the Units for my own account, for investment purposes and not for the
                                    account of others, and with no present intention of reselling them.

_____             _____             If an individual, I am a citizen of the United States of America and at least twenty-one
                                    years of age.

_____             _____             If a partnership, corporation or trust, then I am at least twenty-one years of age and
                                    empowered and duly authorized under a governing document, trust instrument, charter,
                                    certificate of incorporation, by-law provision or the like to enter into this
                                    Subscription Agreement and to perform the transactions contemplated by the Prospectus,
                                    including its exhibits.

_____             _____             I (other than if I am a Minnesota or Maine resident) understand that if I am an
                                    Investor General Partner, then I will have unlimited joint and several liability for
                                    Partnership obligations and liabilities including amounts in excess of my subscription
                                    to the extent the obligations and liabilities exceed the Partnership's insurance
                                    proceeds, the Partnership's assets, and indemnification by the Managing General
                                    Partner. Also, the insurance may be inadequate to cover these liabilities and there is
                                    no insurance coverage for certain claims.

_____             _____             I (other than if I am a Minnesota or Maine resident) understand that if I am a
                                    Limited Partner, then I may only use my Partnership losses to the extent of my net
                                    passive income from passive activities in the year, with any excess losses being
                                    deferred.

_____             _____             I (other than if I am a Minnesota or Maine resident) understand that no state or
                                    federal governmental authority has made any finding or determination relating to the
                                    fairness for public investment of the Units and no state or federal governmental
                                    authority has recommended or endorsed or will recommend or endorse the Units.

_____             _____             I (other than if I am a Minnesota or Maine resident) understand that the Selling
                                    Agent or registered representative is required to inform me and the other potential
                                    investors of all pertinent facts relating to the Units, including the following: the
                                    risks involved in the offering, including the speculative nature of the investment
                                    and the speculative nature of drilling for natural gas and oil; the financial
                                    hazards involved in the offering, including the risk of losing my entire investment;
                                    the lack of liquidity of my investment; the restrictions on transferability of my
                                    Units; the background of the Managing General Partner and the Operator; the tax
                                    consequences of my investment; and the unlimited joint and several liability of the
                                    Investor General Partners.

                                       3

INSTRUCTIONS TO INVESTOR
- ------------------------
You are required to execute your own Subscription Agreement and the Managing
General Partner will not accept any Subscription Agreement that has been
executed by someone other than you unless the person has been given your legal
power of attorney to sign on your behalf, and you meet all of the conditions in
the Prospectus and this Subscription Agreement. In the case of sales to
fiduciary accounts, the minimum standards set forth in the Prospectus and this
Subscription Agreement must be met by the beneficiary, the fiduciary account, or
by the donor or grantor who directly or indirectly supplies the funds to
purchase the Partnership Units if the donor or grantor is the fiduciary.


                                        5

Your execution of the Subscription Agreement constitutes your binding offer to
buy Units in the Partnership. Once you subscribe you may withdraw your
subscription only by providing the Managing General Partner with written notice
of your withdrawal before your subscription is accepted by the Managing General
Partner. The Managing General Partner has the discretion to refuse to accept
your subscription without liability to you. Subscriptions will be accepted or
rejected by the Partnership within 30 days of their receipt. If your
subscription is rejected, then all of your funds will be returned to you
immediately. If your subscription is accepted before the first closing, then you
will be admitted as a Participant not later than 15 days after the release from
escrow of the investors' funds to the Partnership. If your subscription is
accepted after the first closing, then you will be admitted into the Partnership
not later than the last day of the calendar month in which your subscription was
accepted by the Partnership.

The Managing General Partner will not complete a sale of Units to you and send
you a confirmation of purchase until at least five business days after the date
you receive a final Prospectus.

NOTICE TO CALIFORNIA RESIDENTS: This offering deviates in certain respects from
various requirements of Title 10 of the California Administrative Code. These
deviations include, but are not limited to the following: the definition of
Prospect in the Prospectus, unlike Rule 260.140.127.2(b) and Rule
260.140.121(1), does not require enlarging or contracting the size of the area
on the basis of geological data in all cases. If I am a resident of California,
I acknowledge the receipt of California Rule 260.141.11 set forth in Exhibit (B)
to the Prospectus.

     (b)  REPRESENTATIONS AND INDEMNIFICATION ASSOCIATED WITH THE ASSIGNMENT OF
          THE LEASE. The Operator represents and warrants to the Developer that:

          (i)     the Operator is the lawful owner of the Lease and rights and
                  interest under the Lease and of the personal property on the
                  Lease or used in connection with the Lease;

          (ii)    the Operator has good right and authority to sell and convey
                  the rights, interest, and property;

                  attorneys' fees), liabilities, claims, penalties, losses,
                  suits, actions, causes of action, judgments or decrees
                  resulting from the breach of any of the above representations
                  and warranties. It is understood and agreed that, except as
                  specifically set forth above, the Operator makes no warranty
                  or representation, express or implied, as to its title or the
                  title of the lessors in and to the lands or oil and gas

2.   DRILLING OF WELLS; TIMING; DEPTH; INTEREST OF DEVELOPER; RIGHT TO
     SUBSTITUTE WELL LOCATIONS.

     (a)  DRILLING OF WELLS. Operator, as Developer's independent contractor,
          agrees to drill, complete (or plug) and operate ____________ (_____)
          oil and gas wells on the ____________ (______) Initial Well Locations
          in accordance with the terms and conditions of this Agreement.
          Developer, as a minimum commitment, agrees to participate in and pay
          the Operator's charges for drilling and completing the wells and any
          extra costs pursuant to Section 4 in proportion to the share of the
          Working Interest owned by the Developer in the wells with respect to
          all initial wells. It is understood and agreed that, subject to
          sub-section (e) below, Developer does not reserve the right to decline
          participation in the drilling of any of the initial wells to be
          drilled under this Agreement.

     (b)  TIMING. Operator shall begin drilling the first well within thirty
          (30) days after the date of this Agreement, and shall begin drilling
          each of the other initial wells for which payment is made pursuant to
          Section 4(b) of this Agreement before the close of the 90th day after
          the close of the calendar year in which this Agreement is entered into
          by Operator and the Developer. Subject to the foregoing time limits,
          Operator shall determine the timing of and the order of drilling the
          Initial Well Locations.

     (c)  DEPTH. All of the wells to be drilled under this Agreement shall be:

          (i)     drilled and completed (or plugged) in accordance with the
                  generally accepted and customary oil and gas field practices
                  and techniques then prevailing in the geographical area of the
                  Well Locations; and

                                        2


          (ii)    drilled to a depth sufficient to test thoroughly the objective
                  formation or the deepest assigned depth, whichever is less.

     (d)  INTEREST OF DEVELOPER. Except as otherwise provided in this Agreement,
          all costs, expenses, and liabilities incurred in connection with the
          drilling and other operations and activities contemplated by this
          Agreement shall be borne and paid, and all wells, gathering lines of
          up to approximately 2,500 feet on the Well Location in connection with
          a natural gas well, equipment, materials, and facilities acquired,
          constructed or installed under this Agreement shall be owned, by the
          Developer in proportion to the share of the Working Interest owned by
          the Developer in the wells. Subject to the payment of lessor's
          royalties and other royalties and overriding royalties, if any,
          production of oil and gas from the wells to be drilled under this
          Agreement shall be owned by the Developer in proportion to the share
          of the Working Interest owned by the Developer in the wells.

     (e)  RIGHT TO SUBSTITUTE WELL LOCATIONS. Notwithstanding the provisions of
          sub-section (a) above, if the Operator or Developer determines in good
          faith, with respect to any Well Location, before operations begin
          under this Agreement on the Well Location, that it would not be in the
          best interest of the parties to drill a well on the Well Location,
          then the party making the determination shall notify the other party
          of its determination and its basis for its determination and, unless
          otherwise instructed by Developer, the well shall not be drilled. This
          determination may be based on:

          (i)     the production or failure of production of any other wells
                  which may have been recently drilled in the immediate area of
                  the Well Location;

          (ii)    newly discovered title defects; or

          (iii)   any other evidence with respect to the Well Location as may be
                  obtained.

                  If the well is not drilled, then Operator shall promptly
                  propose a new well location (including all information for the
                  Well Location as Developer may reasonably request) to be
                  substituted for the original Well Location. Developer shall
                  then have seven (7) business days to either reject or accept
                  the proposed new well location. If the new well location is
                  rejected, then Operator shall promptly propose another
                  substitute well location pursuant to the provisions of this
                  sub-section.

                  Once the Developer accepts a substitute well location or does
                  not reject it within said seven (7) day period, this Agreement
                  shall terminate as to the original Well Location and the
                  substitute well location shall become subject to the terms and
                  conditions of this Agreement.

3.   OPERATOR - RESPONSIBILITIES IN GENERAL; COVENANTS; TERM.

          completing all initial wells as the Managing General Partner of the
          Developer shall be paid within five (5) business days of notice from
          Operator that the costs have been incurred. The Developer's payment
          shall be nonrefundable in all events in order to enable Operator to do
          the following:

          (i)     commence site preparation for the initial wells;

          (ii)    obtain suitable subcontractors for drilling and completing the
                  wells at currently prevailing prices; and

          (iii)   insure the availability of equipment and materials.

          For purposes of this Agreement, "Intangible Drilling Costs" shall mean
          those expenditures associated with property acquisition and the
          drilling and completion of oil and gas wells that under present law
          are generally accepted as fully deductible currently for federal
          income tax purposes. This includes:

          (i)     all expenditures made with respect to any well before the
                  establishment of production in commercial quantities for
                  wages, fuel, repairs, hauling, supplies and other costs and
                  expenses incident to and necessary for the drilling of the
                  well and the preparation of the well for the production of oil
                  or gas, that are currently deductible pursuant to Section
                  263(c) of the Internal Revenue Code of 1986, as amended (the
                  "Code"), and Treasury Reg. Section 1.612-4, which are
                  generally termed "intangible drilling and development costs";

          (ii)    the expense of plugging and abandoning any well before a
                  completion attempt; and

          (iii)   the costs (other than Tangible Costs and Lease costs) to
                  re-enter and deepen an existing well, complete the well to
                  deeper formations or reservoirs, or plug and abandon the well
                  if it is nonproductive from the targeted deeper formations or
                  reservoirs.

                                        5


          "Tangible Costs" shall mean those costs associated with property
          acquisition and the drilling and completion of oil and gas wells which
          are generally accepted as capital expenditures pursuant to the
          provisions of the Code. This includes:

          (i)     all costs of equipment, parts and items of hardware used in
                  drilling and completing a well;

          (ii)    the costs (other than Intangible Drilling Costs and Lease
                  costs) to re-enter and deepen an existing well, complete the
                  well to deeper formations or reservoirs, or plug and abandon
                  the well if it is nonproductive from the targeted deeper
                  formations or reservoirs; and

          (iii)   those items necessary to deliver acceptable oil and gas
                  production to purchasers to the extent installed downstream
                  from the wellhead of any well and which are required to be
                  capitalized under the Code and its regulations.

          With respect to each additional well drilled on the Additional Well
          Locations, if any, the Developer shall pay to Operator, in proportion
          to the share of the Working Interest owned by the Developer in the
          wells, one hundred percent (100%) of the estimated Intangible Drilling
          Costs and Tangible Costs for drilling and completing the well on
          execution of the applicable addendum pursuant to Section l(c) above.
          Notwithstanding, Atlas' payments for its share of the estimated
          Tangible Costs of drilling and completing all additional wells as the
          Managing General Partner of the Developer shall be paid within five
          (5) business days of notice from Operator that the costs have been
          incurred. The Developer's payment shall be nonrefundable in all events
          in order to enable Operator to do the following:

          (i)     commence site preparation;

          (ii)    obtain suitable subcontractors for drilling and completing the
                  wells at currently prevailing prices; and

          (iii)   insure the availability of equipment and materials.

          Developer shall pay, in proportion to the share of the Working
          Interest owned by the Developer in the wells, any extra costs incurred
          for each well pursuant to sub-section (a) above within ten (10)
          business days of its receipt of Operator's statement for the extra
          costs.

     (c)  COMPLETION DETERMINATION. Operator shall determine whether or not to
          run the production casing for an attempted completion or to plug and
          abandon any well drilled under this Agreement. However, a well shall
          be completed only if Operator has made a good faith determination that
          there is a reasonable possibility of obtaining commercial quantities
          of oil and/or gas.

     (d  DRY HOLE DETERMINATION. If Operator determines at any time during the
          drilling or attempted completion of any well drilled under this
          Agreement, in accordance with the generally accepted and customary oil
          and gas field practices and techniques then prevailing in the
          geographic area of the Well Location that the well should not be
          completed, then it shall promptly and properly plug and abandon the
          well.

     (e)  EXCESS FUNDS AND COST OVERRUNS-INTANGIBLE DRILLING COSTS. Any
          estimated Intangible Drilling Costs (which are the Intangible Drilling
          Costs set forth on the AFE) prepaid by Developer with respect to any
          well which exceed Operator's price specified in sub-section (a) above
          for the Intangible Drilling Costs of the well shall be retained by
          Operator and shall be applied, in proportion to the share of the
          Working Interest owned by the Developer in the wells, to:

          (i)     the Intangible Drilling Costs for an additional well or wells
                  to be drilled on the Additional Well Locations; or

          (ii)    any cost overruns owed by the Developer to Operator for
                  Intangible Drilling Costs on one or more of the other wells on
                  the Well Locations.

                                        6


          Conversely, if Operator's price specified in sub-section (a) above for
          the Intangible Drilling Costs of any well exceeds the estimated
          Intangible Drilling Costs (which are the Intangible Drilling Costs set
          forth on the AFE) prepaid by Developer for the well, then:

          (i)     Developer shall pay the additional price to Operator within
                  five (5) business days after notice from Operator that the
                  additional amount is due and owing; or

          (ii)    Developer and Operator may agree to delete or reduce
                  Developer's Working Interest in one or more wells to be
                  drilled under this Agreement which have not yet been spudded
                  to provide funds to pay the additional amounts owed by
                  Developer to Operator. If doing so results in any excess
                  prepaid Intangible Drilling Costs, then these funds shall be
                  applied, in proportion to the share of the Working Interest
                  owned by the Developer in the wells, to:

                  (a)   the Intangible Drilling Costs for an additional well or
                        wells to be drilled on the Additional Well Locations; or

                  (b)   any cost overruns owed by the Developer to Operator for
                        Intangible Drilling Costs on one or more of the other
                        wells on the Well Locations.

          The Exhibits to this Agreement with respect to the affected wells
          shall be amended as appropriate.

     (f)  EXCESS FUNDS AND COST OVERRUNS - TANGIBLE COSTS. Any estimated
          Tangible Costs (which are the Tangible Costs set forth on the AFE)
          prepaid by Developer with respect to any well which exceed Operator's
          price specified in sub-section (a) above for the Tangible Costs of the
          well shall be retained by Operator and shall be applied, in proportion
          to the share of the Working Interest owned by the Developer in the
          wells, to:

          (i)     the Developer's Participants' share of the Tangible Costs for
                  an additional well or wells to be drilled on the Additional
                  Well Locations; or

          (ii)    any cost overruns owed by the Developer to Operator for the
                  Developer's Participants' share of the Tangible Costs on one
                  or more of the other wells on the Well Locations.

          Conversely, if Operator's price specified in sub-section (a) above for
          the Developer's Participants' share of Tangible Costs of any well
          exceeds the estimated Tangible Costs (which are the Tangible Costs set
          forth on the AFE) prepaid by Developer for the Developer's
          Participants' share of the Tangible Costs for the well, then:

          (i)     Developer shall pay the additional price to Operator within
                  ten (10) business days after notice from Operator that the
                  additional price is due and owing; or

          (ii)    Developer and Operator may agree to delete or reduce
                  Developer's Working Interest in one or more wells to be
                  drilled under this Agreement which have not yet been spudded
                  to provide funds to pay the additional amounts owed by
                  Developer to Operator. If doing so results in any excess
                  prepaid Tangible Costs, then these funds shall be applied, in
                  proportion to the share of the Working Interest owed by the
                  Developer in the wells, to:

                  (a)   the Developer's Participants' share of the Tangible
                        Costs for an additional well or wells to be drilled on
                        the Additional Well Locations; or

                  (b)   any cost overruns owed by the Developer to Operator for
                        the Developer's Participants' share of the Tangible
                        Costs on one or more of the other wells on the Well
                        Locations.

          (iii)   The Developer's Participants' share of the Tangible Costs of
                  all of the wells drilled under this Agreement and any
                  additional wells to be drilled on the Additional Well
                  Locations under any Addendum to this Agreement is ten percent
                  (10%) of the total price prepaid by Developer to Operator
                  pursuant to Section 4(b) of this Agreement or any Addendum
                  hereto. The Developer's Participants' share of the Tangible
                  Costs of any one well drilled under this Agreement shall be
                  determined subject to the preceding sentence, taking into
                  account the Developer's share of all of the Tangible Costs of
                  all of the wells to be drilled under this Agreement and any
                  Addendum hereto.

                                        7


               The Exhibits to this Agreement with respect to the affected wells
          shall be amended as appropriate.

5.        TITLE EXAMINATION OF WELL LOCATIONS, DEVELOPER'S ACCEPTANCE AND
          LIABILITY; ADDITIONAL WELL LOCATIONS.

          (a)  TITLE EXAMINATION OF WELL LOCATIONS, DEVELOPER'S ACCEPTANCE AND
               LIABILITY. The Developer acknowledges that Operator has furnished
               Developer with the title opinions identified on Exhibit A, and
               other documents and information which Developer or its counsel
               has requested in order to determine the adequacy of the title to
               the Initial Well Locations and leased premises subject to this
               Agreement. The Developer accepts the title to the Initial Well
               Locations and leased premises and acknowledges and agrees that,
               except for any loss, expense, cost, or liability caused by the
               breach of any of the warranties and representations made by the
               Operator in Section l(b), any loss, expense, cost or liability
               whatsoever caused by or related to any defect or failure of the
               title shall be the sole responsibility of and shall be borne
               entirely by the Developer.

          (b)  ADDITIONAL WELL LOCATIONS. Before beginning drilling of any well
               on any Additional Well Location, Operator shall conduct, or cause
               to be conducted, a title examination of the Additional Well
               Location, in order to obtain appropriate abstracts, opinions and
               certificates and other information necessary to determine the
               adequacy of title to both the applicable Lease and the fee title
               of the lessor to the premises covered by the Lease. The results
               of the title examination and such other information as is
               necessary to determine the adequacy of title for drilling
               purposes shall be submitted to the Developer for its review and
               acceptance. No drilling on the Additional Well Locations shall
               begin until the title has been accepted in writing by the
               Developer. After any title has been accepted by the Developer,
               any loss, expense, cost, or liability whatsoever, caused by or
               related to any defect or failure of the title shall be the sole
               responsibility of and shall be borne entirely by the Developer,
               unless such loss, expense, cost, or liability was caused by the
               breach of any of the warranties and representations made by the
               Operator in Section l(b).

6.        OPERATIONS SUBSEQUENT TO COMPLETION OF THE WELLS; FEE ADJUSTMENTS;
          EXTRAORDINARY COSTS; PIPELINES; PRICE DETERMINATIONS; PLUGGING AND
          ABANDONMENT.

          (a)  OPERATIONS SUBSEQUENT TO COMPLETION OF THE WELLS. Beginning with
               the month in which a well drilled under this Agreement begins to
               produce, Operator shall be entitled to an operating fee of $285
               per month for each well being operated under this Agreement,
               proportionately reduced to the extent the Developer owns less
               than 100% of the Working Interest in the wells. This fee shall be
               in lieu of any direct charges by Operator for its services or the
               provision by Operator of its equipment for normal superintendence
               and maintenance of the wells and related pipelines and
               facilities.

               The operating fees shall cover all normal, regularly recurring
               operating expenses for the production, delivery and sale of
               natural gas, including without limitation:

               (i)   well tending, routine maintenance and adjustment;

               (ii)  reading meters, recording production, pumping,
                     maintaining appropriate books and records;

               (iii) preparing reports to the Developer and government
                     agencies; and

               (iv)  collecting and disbursing revenues.

               The operating fees shall not cover costs and expenses related to
          the following:

                                        8


               (i)   the production and sale of oil;

               (ii)  the collection and disposal of salt water or other liquids
                     produced by the wells;

               (iii) the rebuilding of access roads; and

               (iv)  the purchase of equipment, materials or third party
                     services;

               which, subject to the provisions of sub-section (c) of this
               Section 6, shall be paid by the Developer in proportion to the
               share of the Working Interest owned by the Developer in the
               wells.

               Any well which is temporarily abandoned or shut-in continuously
               for the entire month shall not be considered a producing well for
               purposes of determining the number of wells in the month subject
               to the operating fee.


          (b)  FEE ADJUSTMENTS. The monthly operating fee set forth in
               sub-section (a) above may be adjusted by Operator annually, as of
               the first day of January (the "Adjustment Date") of each year,
               beginning January 1, 2008. Such adjustment, if any, shall not
               exceed the percentage increase in the average weekly earnings of
               "Crude Petroleum, Natural Gas, and Natural Gas Liquids" workers,
               as published by the U.S. Department of Labor, Bureau of Labor
               Statistics, and shown in Employment and Earnings Publication,
               Monthly Establishment Data, Hours and Earning Statistical Table
               C-2, Index Average Weekly Earnings of "Crude Petroleum, Natural
               Gas, and Natural Gas Liquids" workers, SIC Code #131-2, or any
               successor index thereto, since January l, 2006, in the case of
               the first adjustment, and since the previous Adjustment Date, in
               the case of each subsequent adjustment. In addition, the monthly
               operating fee set forth in sub-section (a) above for any given
               well or wells being operated under this Agreement may be adjusted
               at any time in the Operator's discretion to an amount equal to a
               competitive rate in the area in which the well(s) are situated.


          (c)  EXTRAORDINARY COSTS. Without the prior written consent of the
               Developer, pursuant to a written estimate submitted by Operator,
               Operator shall not undertake any single project or incur any
               extraordinary cost with respect to any well being produced under
               this Agreement reasonably estimated to result in an expenditure
               of more than $5,000, unless the project or extraordinary cost is
               necessary for the following:

               (i)     to safeguard persons or property; or

               (ii)    to protect the well or related facilities in the event of
                       a sudden emergency.

               In no event, however, shall the Developer be required to pay for
               any project or extraordinary cost arising from the negligence or
               misconduct of Operator, its agents, servants, employees,
               contractors, licensees, or invitees.

               All extraordinary costs incurred and the cost of projects
               undertaken with respect to a well being produced shall be billed
               at the invoice cost of third-party services performed or
               materials purchased together with a reasonable charge by Operator
               for services performed directly by it, in proportion to the share
               of the Working Interest owned by the Developer in the wells.
               Operator shall have the right to require the Developer to pay in
               advance of undertaking any project all or a portion of the
               estimated costs of the project in proportion to the share of the
               Working Interest owned by the Developer in the wells.

          (d)  PIPELINES. Developer shall have no interest in the pipeline
               gathering system, which gathering system shall remain the sole
               property of Operator or its Affiliates and shall be maintained at
               their sole cost and expense.

          (e)  PRICE DETERMINATIONS. Notwithstanding anything herein to the
               contrary, the Developer shall pay all costs in proportion to the
               share of the Working Interest owned by the Developer in the wells
               with respect to obtaining price determinations under and
               otherwise complying with the Natural Gas Policy Act of 1978 and
               the implementing state regulations. This responsibility shall
               include, without limitation, preparing, filing, and executing all
               applications, affidavits, interim collection notices, reports and
               other documents necessary or appropriate to obtain price
               certification, to effect sales of natural gas, or otherwise to
               comply with the Act and the implementing state regulations.

                                        9


          Operator agrees to furnish the information and render the assistance
          as the Developer may reasonably request in order to comply with the
          Act and the implementing state regulations without charge for services
          performed by its employees.

     (f)  PLUGGING AND ABANDONMENT. The Developer shall have the right to direct
          Operator to plug and abandon any well that has been completed under
          this Agreement as a producer. In addition, Operator shall not plug and
          abandon any well that has been drilled and completed as a producer
          before obtaining the written consent of the Developer. However, if the
          Operator in accordance with the generally accepted and customary oil
          and gas field practices and techniques then prevailing in the
          geographic area of the well location, determines that any well should
          be plugged and abandoned and makes a written request to the Developer
          for authority to plug and abandon the well and the Developer fails to
          respond in writing to the request within forty-five (45) days
          following the date of the request, then the Developer shall be deemed
          to have consented to the plugging and abandonment of the well.

          All costs and expenses related to plugging and abandoning the wells
          which have been drilled and completed as producing wells shall be
          borne and paid by the Developer in proportion to the share of the
          Working Interest owned by the Developer in the wells. Also, at any
          time after one (1) year from the date each well drilled and completed
          is placed into production, Operator shall have the right to deduct
          each month from the proceeds of the sale of the production from the
          well up to $200, in proportion to the share of the Working Interest
          owned by the Developer in the well, for the purpose of establishing a
          fund to cover the estimated costs of plugging and abandoning the well.
          All of these funds shall be deposited in a separate interest bearing
          escrow account for the account of the Developer, and the total amount
          so retained and deposited shall not exceed Operator's reasonable
          estimate of Developer's share of the costs of plugging and abandoning
          the well.

7.   BILLING AND PAYMENT PROCEDURE WITH RESPECT TO OPERATION OF WELLS;
     DISBURSEMENTS; SEPARATE ACCOUNT FOR SALE PROCEEDS; RECORDS AND REPORTS;
     ADDITIONAL INFORMATION.

     (a)  BILLING AND PAYMENT PROCEDURE WITH RESPECT TO OPERATION OF WELLS.
          Operator shall promptly and timely pay and discharge on behalf of the
          Developer, in proportion to the share of the Working Interest owned by
          the Developer in the wells the following:

          (i)     all expenses and liabilities payable and incurred by reason of
                  its operation of the wells in accordance with this Agreement ,
                  such as severance taxes, royalties, overriding royalties,
                  operating fees, and pipeline gathering charges; and

          (ii)    any third-party invoices rendered to Operator with respect to
                  costs and expenses incurred in connection with the operation
                  of the wells.

          Operator, however, shall not be required to pay and discharge any of
          the above costs and expenses which are being contested in good faith
          by Operator.

          Operator shall:

          (i)     deduct the foregoing costs and expenses from the Developer's
                  share of the proceeds of the oil and/or gas sold from the
                  wells; and

          (ii)    keep an accurate record of the Developer's account, showing
                  expenses incurred and charges and credits made and received
                  with respect to each well.

                                       10


          If the proceeds are insufficient to pay the costs and expenses, then
          Operator shall promptly and timely pay and discharge the costs and
          expenses, in proportion to the share of the Working Interest owned by
          the Developer in the wells, and prepare and submit an invoice to the
          Developer each month for the costs and expenses. The invoice shall be
          accompanied by the form of statement specified in sub-section (b)
          below, and shall be paid by the Developer within ten (10) business
          days of its receipt.

     (b)  DISBURSEMENTS. Operator shall disburse to the Developer, on a monthly
          basis, the Developer's share of the proceeds received from the sale of
          oil and/or gas sold from the wells operated under this Agreement,
          less:

          (i)  the amounts charged to the Developer under sub-section (a); and

          (ii) the amount, if any, withheld by Operator for future plugging
               costs pursuant to sub-section (f) of Section 6.

          Each disbursement made and/or invoice submitted pursuant to
          sub-section (a) above shall be accompanied by a statement itemizing
          with respect to each well:

          (i)     the total production of oil and/or gas since the date of the
                  last disbursement or invoice billing period, as the case may
                  be, and the Developer's share of the production;

          (ii)    the total proceeds received from any sale of the production,
                  and the Developer's share of the proceeds;

          (iii)   the costs and expenses deducted from the proceeds and/or being
                  billed to the Developer pursuant to sub-section (a) above;

          (iv)    the amount withheld for future plugging costs; and

          (v)     any other information as Developer may reasonably request,
                  including without limitation copies of all third-party
                  invoices listed on the statement for the period.

     (c)  SEPARATE ACCOUNT FOR SALE PROCEEDS. Operator agrees to deposit all
          proceeds from the sale of oil and/or gas sold from the wells operated
          under this Agreement in a separate checking account maintained by
          Operator. This account shall be used solely for the purpose of
          collecting and disbursing funds constituting proceeds from the sale of
          production under this Agreement.

     (d)  RECORDS AND REPORTS. In addition to the statements required under
          sub-section (b) above, Operator, within seventy-five (75) days after
          the completion of each well drilled, shall furnish the Developer with
          a detailed statement itemizing with respect to the well the total
          costs and charges under Section 4(a) and the Developer's share of the
          costs and charges, and any information as is necessary to enable the
          Developer:

          (i)     to allocate any extra costs incurred with respect to the well
                  between Tangible Costs and Intangible Drilling Costs; and

          (ii)    to determine the amount of investment tax credit or marginal
                  well production tax credit, if applicable.

     (e)  ADDITIONAL INFORMATION. Operator shall promptly furnish the Developer
          with any additional information as it may reasonably request,
          including without limitation geological, technical, and financial
          information, in the form as may reasonably be requested, pertaining to
          any phase of the operations and activities governed by this Agreement.
          The Developer and its authorized employees, agents and consultants,
          including independent accountants shall, at Developer's sole cost and
          expense:

          (i)     on at least ten (10) days' written notice have access during
                  normal business hours to all of Operator's records pertaining
                  to operations, including without limitation, the right to
                  audit the books of account of Operator relating to all
                  receipts, costs, charges, expenses and disbursements under
                  this Agreement, including information regarding the separate
                  account required under sub-section (c); and

                                       11


          (ii)    have access, at its sole risk, to any wells drilled by
                  Operator under this Agreement at all times to inspect and
                  observe any machinery, equipment and operations.

8.   OPERATOR'S LIEN; RIGHT TO COLLECT FROM OIL OR GAS PURCHASER.

     (a)  OPERATOR'S LIEN. To secure the payment of all sums due from Developer
          to Operator under the provisions of this Agreement the Developer
          grants Operator a first and preferred lien on and security interest in
          the following:

          (i)     the Developer's interest in the Leases covered by this
                  Agreement;

          (ii)    the Developer's interest in oil and gas produced under this
                  Agreement and its proceeds from the sale of the oil and gas;
                  and

          (iii)   the Developer's interest in materials and equipment under this
                  Agreement.

     (b)  RIGHT TO COLLECT FROM OIL OR GAS PURCHASER. If the Developer fails to
          timely pay any amount owing under this Agreement by it to the
          Operator, then Operator, without prejudice to other existing remedies,
          may collect and retain from any purchaser or purchasers of oil or gas
          the Developer's share of the proceeds from the sale of the oil and gas
          until the amount owed by the Developer, plus twelve percent (12%)
          interest on a per annum basis, and any additional costs (including
          without limitation actual attorneys' fees and costs) resulting from
          the delinquency, has been paid. Each purchaser of oil or gas shall be
          entitled to rely on Operator's written statement concerning the amount
          of any default.

9.   SUCCESSORS AND ASSIGNS; TRANSFERS; APPOINTMENT OF AGENT.

     (a)  SUCCESSORS AND ASSIGNS. This Agreement shall be binding on and inure
          to the benefit of the undersigned parties and their respective
          successors and permitted assigns. However, without the prior written
          consent of the Developer, the Operator may not assign, transfer,
          pledge, mortgage, hypothecate, sell or otherwise dispose of any of its
          interest in this Agreement, or any of the rights or obligations under
          this Agreement. Notwithstanding, this consent shall not be required in
          connection with:

          (i)     the assignment of work to be performed for Operator by
                  subcontractors, it being understood and agreed, however, that
                  any assignment to Operator's subcontractors shall not in any
                  manner relieve or release Operator from any of its obligations
                  and responsibilities under this Agreement;

          (ii)    any lien, assignment, security interest, pledge or mortgage
                  arising under Operator's present or future financing
                  arrangements; or

          (iii)   the liquidation, merger, consolidation, or other corporate
                  reorganization or sale of substantially all of the assets of
                  Operator.

          Further, in order to maintain uniformity of ownership in the wells,
          production, equipment, and leasehold interests covered by this
          Agreement, and notwithstanding any other provisions to the contrary,
          the Developer shall not, without the prior written consent of
          Operator, sell, assign, transfer, encumber, mortgage or otherwise
          dispose of any of its interest in the wells, production, equipment or
          leasehold interests covered by this Agreement unless the disposition
          encompasses either:

          (i)     the entire interest of the Developer in all wells, production,
                  equipment and leasehold interests subject to this Agreement;
                  or

          (ii)    an equal undivided interest in all such wells, production,
                  equipment, and leasehold interests.

                                       12


     (b)  TRANSFERS. Subject to the provisions of sub-section (a) above, any
          sale, encumbrance, transfer or other disposition made by the Developer
          of its interests in the wells, production, equipment, and/or leasehold
          interests covered by this Agreement shall be made:

          (i)     expressly subject to this Agreement;

          (ii)    without prejudice to the rights of the Operator; and

          (iii)   in accordance with and subject to the provisions of the Lease.

     (c)  APPOINTMENT OF AGENT. If at any time the interest of the Developer is
          divided among or owned by co-owners, Operator may, at its discretion,
          require the co-owners to appoint a single trustee or agent with full
          authority to do the following:

          (i)     receive notices, reports and distributions of the proceeds
                  from production;

          (ii)    approve expenditures;

          (iii)   receive billings for and approve and pay all costs, expenses
                  and liabilities incurred under this Agreement;

          (iv)    exercise any rights granted to the co-owners under this
                  Agreement;

          (v)     grant any approvals or authorizations required or contemplated
                  by this Agreement;

          (vi)    sign, execute, certify, acknowledge, file and/or record any
                  agreements, contracts, instruments, reports, or documents
                  whatsoever in connection with this Agreement or the activities
                  contemplated by this Agreement; and

          (vii)   deal generally with, and with power to bind, the co-owners
                  with respect to all activities and operations contemplated by
                  this Agreement.

          However, all the co-owners shall continue to have the right to enter
          into and execute all contracts or agreements for their respective
          shares of the oil and gas produced from the wells drilled under this
          Agreement in accordance with sub-section (c) of Section 11.

10.  OPERATOR'S INSURANCE; SUBCONTRACTORS' INSURANCE; OPERATOR'S LIABILITY.

     (a)  OPERATOR'S INSURANCE. Operator shall obtain and maintain at its own
          expense so long as it is Operator under this Agreement all required
          Workmen's Compensation Insurance and comprehensive general public
          liability insurance in amounts and coverage not less than $1,000,000
          per person per occurrence for personal injury or death and $1,000,000
          for property damage per occurrence, which shall include coverage for
          blow-outs and total liability coverage of not less than $10,000,000.

          Subject to the above limits, the Operator's general public liability
          insurance shall be in all respects comparable to that generally
          maintained in the industry with respect to services of the type to be
          rendered and activities of the type to be conducted under this
          Agreement. Operator's general public liability insurance shall, if
          permitted by Operator's insurance carrier:

          (i)     name the Developer as an additional insured party; and

          (ii)    provide that at least thirty (30) days' prior notice of
                  cancellation and any other adverse material change in the
                  policy shall be given to the Developer.

                                       13


          However, the Developer shall reimburse Operator for the additional
          cost, if any, of including it as an additional insured party under the
          Operator's insurance.

          Current copies of all policies or certificates of the Operator's
          insurance coverage shall be delivered to the Developer on request. It
          is understood and agreed that Operator's insurance coverage may not
          adequately protect the interests of the Developer and that the
          Developer shall carry at its expense the excess or additional general
          public liability, property damage, and other insurance, if any, as the
          Developer deems appropriate.

     (b)  SUBCONTRACTORS' INSURANCE. Operator shall require all of its
          subcontractors to carry all required Workmen's Compensation Insurance
          and to maintain such other insurance, if any, as Operator in its
          discretion may require.

     (c)  OPERATOR'S LIABILITY. Operator's liability to the Developer as
          Operator under this Agreement shall be limited to, and Operator shall
          indemnify the Developer and hold it harmless from, claims, penalties,
          liabilities, obligations, charges, losses, costs, damages, or expenses
          (including but not limited to reasonable attorneys' fees) relating to,
          caused by or arising out of:

          (i)     the noncompliance with or violation by Operator, its
                  employees, agents, or subcontractors of any local, state or
                  federal law, statute, regulation, or ordinance;

          (ii)    the negligence or misconduct of Operator, its employees,
                  agents or subcontractors; or

          (iii)   the breach of or failure to comply with any provisions of this
                  Agreement.

11.  INTERNAL REVENUE CODE ELECTION; RELATIONSHIP OF PARTIES; RIGHT TO TAKE
     PRODUCTION IN KIND.

     (a)  INTERNAL REVENUE CODE ELECTION. With respect to this Agreement, each
          of the parties elects under Section 761(a) of the Internal Revenue
          Code of 1986, as amended, to be excluded from the provisions of
          Subchapter K of Chapter 1 of Subtitle A of the Internal Revenue Code
          of 1986, as amended. If the income tax laws of the state or states in
          which the property covered by this Agreement is located contain, or
          may subsequently contain, a similar election, each of the parties
          agrees that the election shall be exercised.

          Beginning with the first taxable year of operations under this
          Agreement, each party agrees that the deemed election provided by
          Section 1.761-2(b)(2)(ii) of the Regulations under the Internal
          Revenue Code of 1986, as amended, will apply; and no party will file
          an application under Section 1.761-2 (b)(3)(i) of the Regulations to
          revoke the election. Each party agrees to execute the documents and
          make the filings with the appropriate governmental authorities as may
          be necessary to effect the election.

     (b)  RELATIONSHIP OF PARTIES. It is not the intention of the parties to
          create, nor shall this Agreement be construed as creating, a mining or
          other partnership or association or to render the parties liable as
          partners or joint venturers for any purpose. Operator shall be deemed
          to be an independent contractor and shall perform its obligations as
          set forth in this Agreement or as otherwise directed by the Developer.

     (c)  RIGHT TO TAKE PRODUCTION IN KIND. Subject to the provisions of Section
          8 above, the Developer shall have the exclusive right to sell or
          dispose of its proportionate share of all oil and gas produced from
          the wells to be drilled under this Agreement, exclusive of production:

          (i)     that may be used in development and producing operations;

          (ii)    unavoidably lost; and

          (iii)   used to fulfill any free gas obligations under the terms of
                  the applicable Lease or Leases.

                                       14


                  Operator shall not have any right to sell or otherwise dispose
                  of the oil and gas. The Developer shall have the exclusive
                  right to execute all contracts relating to the sale or
                  disposition of its proportionate share of the production from
                  the wells drilled under this Agreement.

                  Developer shall have no interest in any gas supply agreements
                  of Operator, except the right to receive Developer's share of
                  the proceeds received from the sale of any gas or oil from
                  wells developed under this Agreement. The Developer agrees to
                  designate Operator or Operator's designated bank agent as the
                  Developer's collection agent in any contracts. On request,
                  Operator shall assist Developer in arranging the sale or
                  disposition of Developer's oil and gas under this Agreement
                  and shall promptly provide the Developer with all relevant
                  information which comes to Operator's attention regarding
                  opportunities for sale of production.

                  If Developer fails to take in kind or separately dispose of
                  its proportionate share of the oil and gas produced under this
                  Agreement, then Operator shall have the right, subject to the
                  revocation at will by the Developer, but not the obligation,
                  to purchase the oil and gas or sell it to others at any time
                  and from time to time, for the account of the Developer at the
                  best price obtainable in the area for the production.
                  Notwithstanding, Operator shall have no liability to Developer
                  should Operator fail to market the production.

                  Any purchase or sale by Operator shall be subject always to
                  the right of the Developer to exercise at any time its right
                  to take in-kind, or separately dispose of, its share of oil
                  and gas not previously delivered to a purchaser. Any purchase
                  or sale by Operator of any other party's share of oil and gas
                  shall be only for reasonable periods of time as are consistent
                  with the minimum needs of the oil and gas industry under the
                  particular circumstances, but in no event for a period in
                  excess of one (1) year.

12.  EFFECT OF FORCE MAJEURE; DEFINITION OF FORCE MAJEURE; LIMITATION.

     (a)  EFFECT OF FORCE MAJEURE. If Operator is rendered unable, wholly or in
          part, by force majeure (as defined below) to carry out any of its
          obligations under this Agreement, including but not limited to
          beginning the drilling of one or more wells by the applicable times
          set forth in Section 2(b), or any Addendum to this Agreement, the
          obligations of the Operator, so far as it is affected by the force
          majeure, shall be suspended during but no longer than, the continuance
          of the force majeure. The Operator shall give to the Developer prompt
          written notice of the force majeure with reasonably full particulars
          concerning it. Operator shall use all reasonable diligence to remove
          the force majeure as quickly as possible to the extent the same is
          within reasonable control.

     (b)  DEFINITION OF FORCE MAJEURE. The term "force majeure" shall mean an
          act of God, strike, lockout, or other industrial disturbance, act of
          the public enemy, war, blockade, public riot, lightning, fire, storm,
          flood, explosion, governmental restraint, unavailability of drilling
          rigs, equipment or materials, plant shut-downs, curtailments by
          purchasers and any other causes whether of the kind specifically
          enumerated above or otherwise, which directly preclude Operator's
          performance under this Agreement and is not reasonably within the
          control of the Operator including, but not limited to, the inability
          of Operator to begin the drilling of the wells subject to this
          Agreement by the applicable times set forth in Section 2(b) or in any
          Addendum to this Agreement due to decisions of third-party operators
          to delay drilling the wells, poor weather conditions, inability to
          obtain drilling permits, access right to the drilling site or title
          problems.

     (c)  LIMITATION. The requirement that any force majeure shall be remedied
          with all reasonable dispatch shall not require the settlement of
          strikes, lockouts, or other labor difficulty affecting the Operator,
          contrary to its wishes. The method of handling these difficulties
          shall be entirely within the discretion of the Operator.

13.  TERM.

     This Agreement shall become effective when executed by Operator and the
     Developer. Except as provided in sub-section (c) of Section 3, this
     Agreement shall continue and remain in full force and effect for the
     productive lives of the wells being operated under this Agreement.

                  IT IS UNLAWFUL TO CONSUMMATE A SALE OR TRANSFER OF THIS
                  SECURITY, OR ANY INTEREST THEREIN, OR TO RECEIVE ANY

                  THE COMMISSIONER OF CORPORATIONS OF THE STATE OF CALIFORNIA,
                  EXCEPT AS PERMITTED IN THE COMMISSIONER'S RULES.

As a condition of qualification of the units for sale in the State of
California, the following rule is hereby delivered to each California purchaser.

                                        4


CALIFORNIA ADMINISTRATIVE CODE, TITLE 10, CH. 3, RULE 260.141.11.
 RESTRICTION ON TRANSFER.


     (a)  The issuer of any security upon which a restriction on transfer has
          been imposed pursuant to Section 260.141.10 or 260.534 shall cause a
          copy of this section to be delivered to each issuee or transferee of
          such security at the time the certificate evidencing the security is
          delivered to the issuee or transferee.


     (b)  It is unlawful for the holder of any such security to consummate a
          sale or transfer of such security, or any interest therein, without
          the prior written consent of the Commissioner (until this condition is
          removed pursuant to Section 260.141.12 of these rules), except:

          (i)     to the issuer;

          (ii)    pursuant to the order or process of any court;

          (iii)   to any person described in Subdivision (i) of Section 25102 of
                  the Code or Section 260.105.14 of these rules;

          (iv)    to the transferor's ancestors, descendants or spouse, or any
                  custodian or trustee for the account of the transferor or the
                  transferor's ancestors, descendants or spouse, or to a
                  transferee by a trustee or custodian for the account of the
                  transferee or the transferee's ancestors, descendants or
                  spouse;

          (v)     to holders of securities of the same class of the same issuer;

          (vi)    by way of gift or donation inter vivos or on death;

          (vii)   by or through a broker-dealer licensed under the Code (either
                  acting as such or as a finder) to a resident of a foreign
                  state, territory or country who is neither domiciled in this
                  state to the knowledge of the broker-dealer, nor actually
                  present in this state if the sale of such securities is not in
                  violation of any securities law of the foreign state,
                  territory or country concerned;

          (viii)  to a broker-dealer licensed under the Code in a principal
                  transaction, or as an underwriter or member of an underwriting
                  syndicate or selling group;

          (ix)    if the interest sold or transferred is a pledge or other lien
                  given by the purchaser to the seller upon a sale of the
                  security for which the Commissioner's written consent is
                  obtained or under this rule not required;

          (x)     by way of a sale qualified under Sections 25111, 25112, 25113
                  or 25121 of the Code, of the securities to be transferred,
                  provided that no order under Section 25140 or Subdivision (a)
                  of Section 25143 is in effect with respect to such
                  qualification;

          (xi)    by a corporation to a wholly-owned subsidiary of such

                  or Subdivision (a) of Section 25143 is in effect with respect
                  to such qualification;

          (xiii)  between residents of foreign states, territories or countries
                  who are neither domiciled nor actually present in this state;

          (xiv)   to the State Controller pursuant to the Unclaimed Property Law
                  or to the administrator of the unclaimed property law of
                  another state;

                                        5


          (xv)    by the State Controller pursuant to the Unclaimed Property Law
                  or by the administrator of the unclaimed property law of
                  another state if, in either such case, such person (i)
                  discloses to potential purchasers at the sale that transfer of
                  the securities is restricted under this rule, (ii) delivers to
                  each purchaser a copy of this rule, and (iii) advises the
                  Commissioner of the name of each purchaser;

          (xvi)   by a trustee to a successor trustee when such transfer does
                  not involve a change in the beneficial ownership of the
                  securities;

          (xvii)  by way of an offer and sale of outstanding securities in an
                  issuer transaction that is subject to the qualification
                  requirement of Section 25110 of the Code but exempt from that
                  qualification requirement by subdivision (f) of Section 25102;

                  provided that any such transfer is on the condition that any
                  certificate evidencing the security issued to such transferee
                  shall contain the legend required by this section.

     (c)  The certificates representing all such securities subject to such a
          restriction on transfer, whether upon initial issuance or upon any
          transfer thereof, shall bear on their face a legend, prominently
          stamped or printed thereon in capital letters of not less than
          10-point size, reading as follows:

          "IT IS UNLAWFUL TO CONSUMMATE A SALE OR TRANSFER OF THIS SECURITY, OR
          ANY INTEREST THEREIN, OR TO RECEIVE ANY CONSIDERATION THEREFOR,
          WITHOUT THE PRIOR WRITTEN CONSENT OF THE COMMISSIONER OF CORPORATIONS
          OF THE STATE OF CALIFORNIA, EXCEPT AS PERMITTED IN THE COMMISSIONER'S
          RULES."

II.  If a resident of IOWA or NORTH CAROLINA, I am aware that:

          IN MAKING AN INVESTMENT DECISION INVESTORS MUST RELY ON THEIR OWN
          EXAMINATION OF THE PERSON OR ENTITY CREATING THE SECURITIES AND THE
          TERMS OF THE OFFERING, INCLUDING THE MERITS AND RISKS INVOLVED. THESE
          SECURITIES HAVE NOT BEEN RECOMMENDED BY ANY FEDERAL OR STATE
          SECURITIES COMMISSION OR REGULATORY AUTHORITY. FURTHERMORE, THE
          FOREGOING AUTHORITIES HAVE NOT CONFIRMED THE ACCURACY OR DETERMINED
          THE ADEQUACY OF THIS DOCUMENT. ANY REPRESENTATION TO THE CONTRARY IS A
          CRIMINAL OFFENSE.

III. PENNSYLVANIA INVESTORS: Because the minimum closing amount is less than 10%
     of the maximum closing amount allowed to a partnership in this offering,
     you are cautioned to carefully evaluate the partnership's ability to fully
     accomplish its stated objectives and inquire as to the current dollar
     volume of partnership subscriptions.

ITEM 17.  UNDERTAKINGS.

The undersigned registrant hereby undertakes:

         (a)(1)   To file, during any period in which offers or sales are being
                  made, a post-effective amendment to this registration
                  statement:

                  (i)      To include any prospectus required by section
                           10(a)(3) of the Securities Act of 1933;

                  (ii)     To reflect in the prospectus any facts or events
                           arising after the effective date of the registration
                           statement (or the most recent post-effective
                           amendment thereof) which, individually or in the
                           aggregate, represent a fundamental change in the
                           information set forth in the registration statement.
                           Notwithstanding the foregoing, any increase or
                           decrease in volume of securities offered (if the
                           total dollar value of securities offered would not
                           exceed that which was registered) and any deviation
                           from the low or high end of the estimated maximum
                           offering range may be reflected in the form of
                           prospectus filed with the Commission pursuant to Rule
                           424(b) (ss. 230.424(b) of this chapter) if, in the
                           aggregate, the changes in volume and price represent
                           no more than 20% change in the maximum aggregate
                           offering price set forth in the "Calculation of
                           Registration Fee" table in the effective registration
                           statement.

                  (iii)    To include any material information with respect to
                           the plan of distribution not previously disclosed in
                           the registration statement or any material change to
                           such information in the registration statement;

                  Provided, however, That:

                                    to be included in a post-effective amendment

                                    information required to be included in a
                                    post-effective amendment by those paragraphs

                                    is part of the registration statement.

                           (C)      Provided further, however, that paragraphs
                                    (a)(1)(i) and (a)(1)(ii) do not apply if the

                           offered therein, and the offering of such securities
                           at that time shall be deemed to be the initial bona
                           fide offering thereof.

                  (3)      To remove from registration by means of a

                                             shall be deemed to be part of and
                                             included in the registration
                                             statement as of the earlier of the

                                             first used after effectiveness or

                                             described in the prospectus. As
                                             provided in Rule 430B, for

                                             time shall be deemed to be the
                                             initial bona fide offering thereof.
                                             Provided, however, that no

                                             or deemed incorporated by reference

                                             prospectus that was part of the
                                             registration statement or made in
                                             any such document immediately prior
                                             to such effective date; or

                           (ii)     If the registrant is subject to Rule 430C

                                    first used after effectiveness. Provided,
                                    however, that no statement made in a

                                    modify any statement that was made in the

                           purchaser in the initial distribution of the

                           registrant pursuant to this registration statement,
                           regardless of the underwriting method used to sell
                           the securities to the purchaser, if the securities
                           are offered or sold to such purchaser by means of any

                                    undersigned registrant or used or referred
                                    to by the undersigned registrant;

                           (iii)    The portion of any other free writing
                                    prospectus relating to the offering
                                    containing material information about the
                                    undersigned registrant or its securities
                                    provided by or on behalf of the undersigned
                                    registrant; and

                           (iv)     Any other communication that is an offer in
                                    the offering made by the undersigned
                                    registrant to the purchaser.

         (b)      The undersigned registrant hereby undertakes that, for
                  purposes of determining any liability under the Securities Act
                  of 1933, each filing of the registrant's annual report
                  pursuant to section 13(a) or section 15(d) of the Securities
                  Exchange Act of 1934 (and, where applicable, each filing of an
                  employee benefit plan's annual report pursuant to section
                  15(d) of the Securities Exchange Act of 1934) that is
                  incorporated by reference in the registration statement shall
                  be deemed to be a new registration statement relating to the
                  securities offered therein, and the offering of such
                  securities at that time shall be deemed to be the initial bona
                  fide offering thereof.

         (c)      The undersigned registrant hereby undertakes to supplement the
                  prospectus, after the expiration of the subscription period,
                  to set forth the results of the subscription offer, the
                  transactions by the underwriters during the subscription
                  period, the amount of unsubscribed securities to be purchased
                  by the underwriters, and the terms of any subsequent
                  reoffering thereof. If any public offering by the underwriters
                  is to be made on terms differing from those set forth on the
                  cover page of the prospectus, a post-effective amendment will
                  be filed to set forth the terms of such offering.

         (d)      The undersigned registrant hereby undertakes (1) to use its
                  best efforts to distribute prior to the opening of bids, to
                  prospective bidders, underwriters, and dealers, a reasonable
                  number of copies of a prospectus which at that time meets the
                  requirements of section 10(a) of the Act, and relating to the
                  securities offered at competitive bidding, as contained in the
                  registration statement, together with any supplements thereto,
                  and (2) to file an amendment to the registration statement
                  reflecting the results of bidding, the terms of the reoffering
                  and related matters to the extent required by the applicable
                  form, not later than the first use, authorized by the issuer
                  after the opening of bids, of a prospectus relating to the
                  securities offered at competitive bidding, unless no further
                  public offering of such securities by the issuer and no
                  reoffering of such securities by the purchasers is proposed to
                  be made.

         (e)      The undersigned registrant hereby undertakes to deliver or
                  cause to be delivered with the prospectus, to each person to
                  whom the prospectus is sent or given, the latest annual report
                  to security holders that is incorporated by reference in the
                  prospectus and furnished pursuant to and meeting the
                  requirements of Rule 14a-3 or Rule 14c-3 under the Securities
                  Exchange Act of 1934; and, where interim financial information
                  required to be presented by Article 3 of Regulation S-X are
                  not set forth in the prospectus, to deliver, or cause to be
                  delivered to each person to whom the prospectus is sent or
                  given, the latest quarterly report that is specifically
                  incorporated by reference in the prospectus to provide such
                  interim financial information.

         (f)      The undersigned registrant hereby undertakes to provide to the
                  underwriter at the closing specified in the underwriting
                  agreements certificates in such denominations and registered
                  in such names as required by the underwriter to permit prompt
                  delivery to each purchaser.


                                       6



         (g)(1)   The undersigned registrant hereby undertakes as follows:
                  that prior to any public reoffering of the securities
                  registered hereunder through use of a prospectus which is a
                  part of this registration statement, by any person or party
                  who is deemed to be an underwriter within the meaning of Rule
                  145(c), the issuer undertakes that such reoffering prospectus
                  will contain the information called for by the applicable
                  registration form with respect to reofferings by persons who
                  may be deemed underwriters, in addition to the information
                  called for by the other Items of the applicable form.

            (2)   The undersigned registrant hereby undertakes that every
                  prospectus (i) that is filed pursuant to paragraph (h) (1)
                  immediately preceding, or (ii) that purports to meet the
                  requirements of section 10(a)(3) of the Act and is used in
                  connection with an offering of securities subject to Rule 415
                  (ss. 230.415 of this chapter), will be filed as a part of an
                  amendment to the registration statement and will not be used
                  until such amendment is effective, and that, for purposes of
                  determining any liability under the Securities Act of 1933,
                  each such post-effective amendment shall be deemed to be a new
                  registration statement relating to the securities offered
                  therein, and the offering of such securities at that time
                  shall be deemed to be the initial bona fide offering thereof.

         (h)      Insofar as indemnification for liabilities arising under the
                  Securities Act of 1933 may be permitted to directors, officers
                  and controlling persons of the registrant pursuant to the
                  foregoing provisions, or otherwise, the registrant has been
                  advised that in the opinion of the Securities and Exchange
                  Commission such indemnification is against public policy as
                  expressed in the Act and is, therefore, unenforceable. In the
                  event that a claim for indemnification against such
                  liabilities (other than the payment by the registrant of
                  expenses incurred or paid by a director, officer or
                  controlling person of the registrant in the successful defense
                  of any action, suit or proceeding) is asserted by such
                  director, officer or controlling person in connection with the
                  securities being registered, the registrant will, unless in
                  the opinion of its counsel the matter has been settled by
                  controlling precedent, submit to a court of appropriate
                  jurisdiction the question whether such indemnification by it
                  is against public policy as expressed in the Act and will be
                  governed by the final adjudication of such issue.

         (i)      The undersigned registrant hereby undertakes that:

                  (1)      For purposes of determining any liability under the
                           Securities Act of 1933, the information omitted from
                           the form of prospectus filed as part of this
                           registration statement in reliance upon Rule 430A and
                           contained in a form of prospectus filed by the
                           registrant pursuant to Rule 424(b)(1) or (4) or
                           497(h) under the Securities Act shall be deemed to be
                           part of this registration statement as of the time it
                           was declared effective.

                  (2)      For the purpose of determining any liability under
                           the Securities Act of 1933, each post-effective
                           amendment that contains a form of prospectus shall be
                           deemed to be a new registration statement relating to
                           the securities offered therein, and the offering of
                           such securities at that time shall be deemed to be
                           the initial bona fide offering thereof.

         (j)      The undersigned registrant hereby undertakes to file an
                  application for the purpose of determining the eligibility of
                  the trustee to act under subsection (a) of section 310 of the
                  Trust Indenture Act ("Act") in accordance with the rules and
                  regulations prescribed by the Commission under section
                  305(b)(2) of the Act.

         (k)      The undersigned registrant hereby undertakes that, for
                  purposes of determining any liability under the Securities Act
                  of 1933, each filing of the annual report pursuant to section
                  13(a) or section 15(d) of the Securities Exchange Act of 1934
                  of a third party that is incorporated by reference in the
                  registration statement in accordance with Item 1100(c)(1) of
                  Regulation AB (17 CFR 229.1100(c)(1)) shall be deemed to be a
                  new registration statement relating to the securities offered
                  therein, and the offering of such securities at that time
                  shall be deemed to be the initial bona fide offering thereof.

         (l)      The undersigned registrant hereby undertakes that, except as
                  otherwise provided by Item 1105 of Regulation AB (17 CFR
                  229.1105), information provided in response to that Item
                  pursuant to Rule 312 of Regulation S-T (17 CFR 232.312)

                  deemed to be a part of the prospectus included in the
                  registration statement. In addition, the undersigned
                  registrant hereby undertakes to provide to any person without
                  charge, upon request, a copy of the information provided in
                  response to Item 1105 of Regulation AB pursuant to Rule 312 of
                  Regulation S-T through the specified Internet address as of
                  the date of the prospectus included in the registration
                  statement if a subsequent update or change is made to the
