                        sales target;

                (ii)    the location of the training and education meeting is
                        appropriate to the purpose of the meeting as defined in

                (iii)   the payment or reimbursement is not applied to the
                        expenses of guests of the registered representative;

                        target; and

                (v)     the recordkeeping requirements are met.

                        by the 2.5% Dealer-Manager fee, the 7% Sales Commission,

                        Agents' bona fide due diligence expenses, which shall
                        not be paid to you; and

                (ii)    registered investment advisors and their clients and

                        price reduced by the 7% Sales Commission, which shall
                        not be paid to you, although their subscription price

                        as described above have been received by the respective
                        Partnership and accepted by the respective Partnership;

                Prospectus.

        (b)     If any event affecting a Partnership or the Managing General
                Partner occurs that in the opinion of the Managing General
                Partner should be set forth in a supplement or amendment to the
                Prospectus, then the Managing General Partner shall promptly at
                its expense prepare and furnish to you a sufficient number of
                copies of a supplement or amendment to the Prospectus so that
                it, as so supplemented or amended, will not contain an untrue
                statement of a material fact or omit to state any material fact
                necessary in order to make the statements in the Prospectus, in
                the light of the circumstances under which they are made, not
                misleading.

6.      REPRESENTATIONS AND WARRANTIES OF THE DEALER-MANAGER. You, as the
        Dealer-Manager, represent and warrant to the Managing General Partner
        and the respective Partnership that:

        (a)     You are a corporation duly organized, validly existing and in
                good standing under the laws of the state of your formation or
                of any jurisdiction to the laws of which you are subject, with
                all requisite power and authority to enter into this Agreement
                and to carry out your obligations under this Agreement.

        (b)     This Agreement when accepted and approved by you shall be duly
                authorized, executed, and delivered by you and shall be a valid
                and binding agreement on your part in accordance with its terms.

        (c)     The consummation of the transactions contemplated by this
                Agreement and the Prospectus shall not result in the following:

                (i)     any breach of any of the terms or conditions of, or a
                        default under your Articles of Incorporation or Bylaws,
                        or any other indenture, agreement, or instrument to
                        which you are a party or by which you are bound; or

                (ii)    any violation of any order applicable to you of any
                        court or regulatory body or administrative agency having

        (d)     You are duly registered under the provisions of the Securities
                Exchange Act of 1934, which is referred to as the "Act of 1934,"
                as a broker or dealer, and you are a member in good standing of
                the NASD. You are duly registered as a broker/dealer in the
                states where you are required to be registered in order to carry

                insofar as the Act applies to your and their activities under
                this Agreement. Further, you and the Selling Agents shall not

                of the Units not to comply with the Act, the

                SUITABILITY

                        (A)     A member or person associated with a member
                                shall not underwrite or participate in a public
                                offering of a direct participation program
                                unless standards of suitability have been
                                established by the program for participants
                                therein and such standards are fully disclosed
                                in the prospectus and are consistent with the
                                provisions of subparagraph (B) of this section.

                        (B)     In recommending to a participant the purchase,
                                sale or exchange of an interest in a direct
                                participation program, a member or person
                                associated with a member shall:

                                (i)     have reasonable grounds to believe, on
                                        the basis of information obtained from
                                        the participant concerning his
                                        investment objectives, other
                                        investments, financial situation and
                                        needs, and any other information known
                                        by the member or associated person,
                                        that:

                                        (a)  the participant is or will be in a
                                             financial position appropriate to
                                             enable him to realize to a
                                             significant extent the benefits
                                             described in the prospectus,
                                             including the tax benefits where
                                             they are a significant aspect of
                                             the program;

                                        (b)  the participant has a fair market
                                             net worth sufficient to sustain the
                                             risks inherent in the program,
                                             including loss of investment and
                                             lack of liquidity; and

                                        (c)  the program is otherwise suitable
                                             for the participant; and

                                (ii)    maintain in the files of the member
                                        documents disclosing the basis upon
                                        which the determination of suitability
                                        was reached as to each participant.

                        (C)     Notwithstanding the provisions of subparagraphs
                                (A) and (B) hereof, no member shall execute any
                                transaction in a direct participation program in
                                a discretionary account without prior written
                                approval of the transaction by the customer.

                                grounds to believe, based on information made
                                available to him by the sponsor through a
                                prospectus or other materials, that all

                                disclosed and provide a basis for evaluating the

                                (i)     items of compensation;

                                (ii)    physical properties;

                                that:

                                (i)     the member or person associated with a
                                        member has reasonable grounds to believe
                                        that such inquiry was conducted with due
                                        care;

                                (ii)    the results of the inquiry were provided
                                        to the member or person associated with
                                        a member with the consent of the member
                                        or members conducting or directing the
                                        inquiry; and

                                (iii)   no member that participated in the
                                        inquiry is a sponsor of the program or
                                        an affiliate of such sponsor.

                        (D)     Prior to executing a purchase transaction in a
                                direct participation program, a member or person
                                associated with a member shall inform the
                                prospective participant of all pertinent facts
                                relating to the liquidity and marketability of
                                the program during the term of investment.

                You and the Selling Agents shall maintain records on the
                information used to determine that the investment in the Units
                is suitable and appropriate for each subscriber, and shall
                maintain these records for at least six years after the Offering
                Termination Date for the respective Partnership.

        (f)     You agree to advise the Managing General Partner in writing of
                each jurisdiction in which you and the Selling Agents propose to
                offer or sell the Units; and you shall not nor shall you permit
                any Selling Agent to offer or sell the Units in any jurisdiction
                until you have been advised in writing by the Managing General
                Partner, or the Managing General Partner's special counsel, that
                the offer or sale of the Units:

                (i)     has been qualified in the jurisdiction;

                (ii)    is exempt from the qualification requirements imposed by
                        the jurisdiction; or

                                        8


                (iii)   the qualification is otherwise not required.

        (g)     You and the Selling Agents have received copies of the
                Prospectus relating to the Units and you and the Selling Agents
                have relied only on the statements contained in the Prospectus
                and not on any other statements whatsoever, either written or
                oral, with respect to the details of the offering of Units.

                delivers subscription funds to the escrow agent), or earlier if
                required by the Blue Sky or securities laws of any state. Unless

                        Prospectus to every person who has previously received a
                        copy of the Prospectus from you and/or the Selling

                        statements made, in light of the circumstances under
                        which they were made, not misleading in connection with
                        the Partnerships, the Units or the offering; and

                (iv)    not to provide any written information, statements, or

                        requirements set forth in the Prospectus, the

                (ii)    the prospective purchasers properly complete and execute
                        the Subscription Agreement, which has been provided as

                        of the Prospectus, together with any additional forms
                        provided in any supplement or amendment to the

                        General Partner to be completed by prospective
                        purchasers.

                The Managing General Partner shall have the right to reject any
                subscription at any time for any reason without liability to it.
                Subscription funds and executed Subscription Agreements shall be
                transmitted as set forth in Section 16 of this Agreement.

        (l)     Although not anticipated, if you assist in any transfers of the
                Units, then you shall comply, and you shall require any Selling
                Agent to comply, with the requirements of Rule 2810(b)(2)(B) and
                (b)(3)(D) of the NASD Conduct Rules.

                                       10


        (m)     You agree and covenant that:

                (i)     the representations and warranties you make in this
                        Agreement are and shall be true and correct at the
                        applicable closing date; and

                (ii)    you shall have fulfilled all your obligations under this
                        Agreement at the applicable closing date.

7.      STATE SECURITIES REGISTRATION. Incident to the offer and sale of the
        Units, the Managing General Partner shall use its best efforts either in
        taking:

        (a)     all necessary action and filing all necessary forms and
                documents deemed reasonable by it in order to qualify or
                register Units for sale under the securities laws of the
                jurisdictions requested by you pursuant to Section 6(f) of this
                Agreement; or

        (b)     any necessary action and filing any necessary forms deemed
                reasonable by it in order to obtain an exemption from
                qualification or registration in those jurisdictions.

        Notwithstanding, the Managing General Partner may elect not to qualify
        or register Units in any state or jurisdiction in which it deems the
        qualification or registration is not warranted for any reason in its
        sole discretion. The Managing General Partner and its counsel shall
        inform you as to the states and jurisdictions in which the Units have
        been qualified for sale or are exempt under the respective securities or
        Blue Sky laws of those states and jurisdictions. The Managing General
        Partner, however, has not assumed and will not assume any obligation or
        responsibility as to your right or any Selling Agent's right to act as a
        broker/dealer with respect to the Units in any state or jurisdiction.

        The Managing General Partner shall provide to you and the Selling Agents
        for delivery to all offerees and purchasers and their representatives
        any additional information, documents, and instruments that the Managing
        General Partner deems necessary to comply with the rules, regulations,
        and judicial and administrative interpretations in those states and
        jurisdictions for the offer and sale of the Units in those states.

        The Managing General Partner shall file all post-offering forms,
        documents, or materials and take all other actions required by the
        states and jurisdictions in which the offer and sale of Units have been
        qualified, registered, or are exempt. However, the Managing General
        Partner shall not be required to take any action, make any filing, or
        prepare any document necessary or required in connection with your
        status or any Selling Agent's status as a broker/dealer under the laws
        of any state or jurisdiction.

        The Managing General Partner shall provide you with copies of all
        applications, filings, correspondence, orders, other documents, or
        instruments relating to any application for qualification, registration,
        exemption, or other approval under applicable state or Federal
        securities laws for the offering.

8.      EXPENSE OF SALE. The expenses in connection with the offer and sale of
        the Units shall be payable as set forth below.

        (a)     The Managing General Partner shall pay all expenses incident to
                the performance of its obligations under this Agreement,
                including the fees and expenses of its attorneys and accountants
                and all fees and expenses of registering or qualifying the Units
                for offer and sale in the states and jurisdictions as set forth
                in Section 7 of this Agreement, or obtaining exemptions from
                qualification or registration, even if the offering of the
                Partnerships is not successfully completed.

                                       11


        (b)     You shall pay all expenses incident to the performance of your
                obligations under this Agreement, including the formation and
                management of the selling group and the fees and expenses of
                your own counsel and accountants, even if the offering of the
                Partnerships is not successfully completed.

9.      CONDITIONS OF THE DEALER-MANAGER'S DUTIES. Your obligations under this
        Agreement shall be subject to the accuracy, as of the date of this
        Agreement and at the applicable closing date of:

        (a)     the Managing General Partner's representations and warranties
                made in this Agreement; and

        (b)     to the performance by the Managing General Partner of its
                obligations under this Agreement.

10.     CONDITIONS OF THE MANAGING GENERAL PARTNER'S DUTIES. The Managing
        General Partner's obligations provided under this Agreement, including
        the duty to pay compensation to you as set forth in Section 4 of this
        Agreement, shall be subject to the following:

        (a)     the accuracy, as of the date of this Agreement and at the
                applicable closing date of each Partnership as if made at the
                applicable closing date, of your representations and warranties
                made in this Agreement;

        (b)     the performance by you of your obligations under this Agreement;
                and

        (c)     the Managing General Partner's receipt, at or before the
                applicable closing date of each Partnership, of a fully executed
                Subscription Agreement for each prospective purchaser as
                required by Section 6(k) of this Agreement.

11.     INDEMNIFICATION.

        (a)     You and the Selling Agents shall indemnify and hold harmless the
                Managing General Partner, each Partnership and its attorneys
                against any losses, claims, damages or liabilities, joint or
                several, to which they may become subject under the Act, the Act
                of 1934, or otherwise insofar as the losses, claims, damages, or
                liabilities (or actions in respect thereof) arise out of or are
                based on your agreements with the Selling Agents or your breach
                of any of your duties and obligations, representations, or
                warranties under the terms or provisions of this Agreement, and
                you and the Selling Agents shall reimburse them for any legal or
                other expenses reasonably incurred in connection with
                investigating or defending the losses, claims, damages,
                liabilities, or actions.

        (b)     The Managing General Partner shall indemnify and hold you and
                the Selling Agents harmless against any losses, claims, damages
                or liabilities, joint or several, to which you and the Selling
                Agents may become subject under the Act, the Act of 1934, or
                otherwise insofar as the losses, claims, damages, or liabilities
                (or actions in respect thereof) arise out of or are based on the
                Managing General Partner's breach of any of its duties and
                obligations, representations, or warranties under the terms or
                provisions of this Agreement, and the Managing General Partner
                shall reimburse you and the Selling Agents for any legal or
                other expenses reasonably incurred in connection with
                investigating or defending the losses, claims, damages,
                liabilities, or actions.

        (c)     The foregoing indemnity agreements shall extend on the same
                terms and conditions to, and shall inure to the benefit of, each
                person, if any, who controls each indemnified party within the
                meaning of the Act.

                                       12


        (d)     Promptly after receipt by an indemnified party of notice of the
                commencement of any action, the indemnified party shall, if a
                claim in respect of the action is to be made against an
                indemnifying party under this Section, notify the indemnifying
                party in writing of the commencement of the action; but the
                omission to promptly notify the indemnifying party shall not
                relieve the indemnifying party from any liability which it may
                have to any indemnified party. If any action is brought against
                an indemnified party, it shall notify the indemnifying party of
                the commencement of the action, and the indemnifying party shall
                be entitled to participate in, and, to the extent that it
                wishes, jointly with any other indemnifying party similarly
                notified, to assume the defense of the action, with counsel
                satisfactory to the indemnified and indemnifying parties. After
                the indemnified party has received notice from the agreed on
                counsel that the defense of the action under this paragraph has
                been assumed, the indemnifying party shall not be responsible
                for any legal or other expenses subsequently incurred by the
                indemnified party in connection with the defense of the action
                other than with respect to the agreed on counsel who assumed the
                defense of the action.

12.     REPRESENTATIONS AND AGREEMENTS TO SURVIVE DELIVERY. All representations,
        warranties, and agreements of the Managing General Partner and you in
        this Agreement, including the indemnity agreements contained in Section
        11 of this Agreement, shall:

        (a)     survive the delivery, execution and closing of this Agreement;

        (b)     remain operative and in full force and effect regardless of any
                investigation made by or on behalf of you or any person who
                controls you within the meaning of the Act, by the Managing
                General Partner, or any of its officers, directors, or any
                person who controls the Managing General Partner within the
                meaning of the Act, or any other indemnified party; and

        (c)     survive delivery of the Units.

                the indemnification provisions of Section 11 of this Agreement

                closing date:

                        of its obligations under this Agreement; or

                (ii)    there has occurred an event materially and adversely
                        affecting the value of the Units.

        subscription proceeds of $2,000,000 of each Partnership as set forth in

                                ESCROW AGREEMENT

        THIS AGREEMENT is made to be effective as of ________________, 2005, by
and among Atlas Resources, Inc., a Pennsylvania corporation (the "Managing
General Partner"), Anthem Securities, Inc., a Pennsylvania corporation
("Anthem"), the "Dealer-Manager," Atlas America Public #15-2005(A) L.P., a
Delaware limited partnership (the "Partnership") and National City Bank of
Pennsylvania, Pittsburgh, Pennsylvania, as escrow agent (the "Escrow Agent").

                                   WITNESSETH:

        WHEREAS, the Managing General Partner intends to offer publicly for sale
to qualified investors (the "Investors") up to __________ investor general
partner interests and up to __________ limited partner interests in the

investors who buy Units through the officers and directors of the Managing
General Partner. Also, the Managing General Partner, in its discretion, may

and under which Anthem has been authorized to select certain members in good

        WHEREAS, the Anthem Dealer-Manager Agreement, the "Dealer-Manager

Investors, which compensation includes, but is not limited to, for each Unit

        o       a .5% accountable Reimbursement for Permissible Non-Cash
                Compensation; and

        o       an up to .5% reimbursement of the Selling Agents' bona fide due
                diligence expenses;

        WHEREAS, the Units may also be offered and sold by the officers and

        o       receipt of the maximum Subscription Proceeds of $150,000,000; or

        o       December 31, 2005.

        WHEREAS, to facilitate compliance with the terms of the Dealer-Manager
Agreement and Rule 15c2-4 adopted under the Securities Exchange Act of 1934, the
Managing General Partner and the Dealer-Manager desire to have the Subscription
Proceeds deposited with the Escrow Agent and the Escrow Agent agrees to hold the
Subscription Proceeds under the terms and conditions set forth in this
Agreement.

        NOW, THEREFORE, in consideration of the mutual covenants and conditions
contained in this Agreement, the parties to this Agreement, intending to be
legally bound, agree as follows:

1.      APPOINTMENT OF ESCROW AGENT. The Managing General Partner, the
        Partnership, and the Dealer-Manager appoint the Escrow Agent as the
        escrow agent to receive and to hold the Subscription Proceeds deposited
        with the Escrow Agent by the Dealer-Manager and the Managing General
        Partner under this Agreement, and the Escrow Agent agrees to serve in
        this capacity during the term and based on the provisions of this
        Agreement.

2.      DEPOSIT OF SUBSCRIPTION PROCEEDS. Pending receipt of the minimum
        Subscription Proceeds of $2,000,000, the Dealer-Manager and the Managing
        General Partner shall deposit the Subscription Proceeds of each Investor
        to whom they sell Units with the Escrow Agent and shall deliver to the
        Escrow Agent a copy of the "Subscription Agreement," which is the
        execution and subscription instrument signed by the Investor to evidence
        his agreement to purchase Units in the Partnership. Payment for each
        subscription for Units shall be in the form of a check or wire made
        payable to "Atlas America Public #15-2005(A) L.P., Escrow Agent,
        National City Bank of Pennsylvania."

3.      INVESTMENT OF SUBSCRIPTION PROCEEDS. The Subscription Proceeds shall be
        deposited in an interest bearing account maintained by the Escrow Agent
        as directed by the Managing General Partner. This may be a savings
        account, bank money market account, short-term certificates of deposit
        issued by a bank, or short-term certificates of deposit issued or
        guaranteed by the United States government. The interest earned shall be
        added to the Subscription Proceeds and disbursed in accordance with the
        provisions of Paragraph 4 or 5 of this Agreement, as the case may be.

4.      DISTRIBUTION OF SUBSCRIPTION PROCEEDS. If the Escrow Agent:

        (a)     receives proper written notice from an authorized officer of the
                Managing General Partner that at least the minimum Subscription
                Proceeds of $2,000,000 have been received and accepted by the
                Managing General Partner; and

        (b)     determines that Subscription Proceeds for at least $2,000,000
                are Distributable Subscription Proceeds;

                                       2


        then the Escrow Agent shall promptly release and distribute to the
        Managing General Partner the Distributable Subscription Proceeds plus
        any interest paid and investment income earned on the Subscription
        Proceeds while held by the Escrow Agent in the escrow account. For
        purposes of the Agreement, "Distributable Subscription Proceeds" are
        Subscription Proceeds which have been deposited in the escrow account
        (1) by wire transfer; and (2) by check, but in the case of checks only
        at the time that the Escrow Agent believes an amount of time has passed
        which would usually be sufficient for Subscription Proceeds paid by
        check to have returned unpaid by the bank on which the check was drawn
        and after a 10 day period from the date of deposit.

        After the occurrence of 4(a) and (b) above, Escrow Agent will provide a
        letter to the Managing General Partner confirming receipt of checks
        and/or wires representing Subscription Proceeds totaling at least
        $2,000,000 have been received and the anticipated date the funds will be
        considered Distributable Subscription Proceeds.

        After the initial distribution, any remaining Subscription Proceeds,
        plus any interest paid and investment income earned on the Subscription
        Proceeds while held by the Escrow Agent in the escrow account, shall be
        promptly released and distributed to the Managing General Partner by the
        Escrow Agent as the Subscription Proceeds become Distributable
        Subscription Proceeds after a 10 day period from the date of deposit.

        The Managing General Partner shall immediately return to the Escrow
        Agent any Subscription Proceeds distributed to the Managing General
        Partner or refunded to an Investor to the extent that such Subscription
        Proceeds were paid by a check which is returned or otherwise not
        collected for any reason prior or subsequent to termination of this
        Agreement.

5.      SEPARATE PARTNERSHIP ACCOUNT. During the continuation of the offering
        after the Partnership is funded with cleared Subscription Proceeds of at
        least $2,000,000 and the Escrow Agent receives the notice described in
        Paragraph 4 of this Agreement, and before the Offering Termination Date,
        any additional Subscription Proceeds may be deposited by the
        Dealer-Manager and the Managing General Partner directly in a separate
        Partnership account which shall not be subject to the terms of this
        Agreement.

6.      DISTRIBUTIONS TO SUBSCRIBERS.

        (a)     If the Partnership is not funded as contemplated because less
                than the minimum Subscription Proceeds of $2,000,000 have been
                received and accepted by the Managing General Partner by twelve
                (12:00) p.m. (noon), local time, EASTERN STANDARD TIME on the
                Offering Termination Date, or for any other reason, then the
                Managing General Partner shall notify the Escrow Agent, and the
                Escrow Agent promptly shall distribute to each Investor, for
                which Escrow Agent has a copy of the subscription agreement, a
                refund check made payable to the Investor in an amount equal to
                the Subscription Proceeds of the Investor, plus any interest
                paid or investment income earned on the Investor's Subscription
                Proceeds while held by the Escrow Agent in the escrow account.

        (b)     If a subscription for Units submitted by an Investor is rejected
                by the Managing General Partner for any reason after the
                Subscription Proceeds relating to the subscription have been
                deposited with the Escrow Agent, then the Managing General
                Partner promptly shall notify in writing, the Escrow Agent of
                the rejection, and the Escrow Agent shall promptly distribute to
                the Investor for which Escrow Agent has a copy of a Subscription
                Agreement, a refund check made payable to the Investor in an
                amount equal to the Subscription Proceeds of the Investor, plus
                any interest paid or investment income earned on the Investor's
                Subscription Proceeds while held by the Escrow Agent in the
                escrow account.

                                       3


7.      COMPENSATION AND EXPENSES OF ESCROW AGENT. The Managing General Partner
        shall be solely responsible for and shall pay the compensation of the
        Escrow Agent for its services under this Agreement, as provided in
        Appendix 1 to this Agreement and made a part of this Agreement, and the
        charges, expenses (including any reasonable attorneys' fees), and other
        out-of-pocket expenses incurred by the Escrow Agent in connection with
        the administration of the provisions of this Agreement. The Escrow Agent
        shall have no lien on the Subscription Proceeds deposited in the escrow
        account unless and until the Partnership is funded with cleared
        Subscription Proceeds of at least $2,000,000 and the Escrow Agent
        receives the proper written notice described in Paragraph 4 of this
        Agreement, at which time the Escrow Agent shall have, and is granted, a
        prior lien on any property, cash, or assets held under this Agreement,
        with respect to its unpaid compensation and nonreimbursed expenses,
        superior to the interests of any other persons or entities.

8.      DUTIES OF ESCROW AGENT. The Escrow Agent shall not be obligated to
        accept any notice, make any delivery, or take any other action under
        this Agreement unless the notice or request or demand for delivery or
        other action is in writing and given or made by the Managing General
        Partner or an authorized officer of the Managing General Partner. In no
        event shall the Escrow Agent be obligated to accept any notice, request,
        or demand from anyone other than the Managing General Partner.

9.      LIABILITY OF ESCROW AGENT. The Escrow Agent shall not be liable for any
        damages, or have any obligations other than the duties prescribed in
        this Agreement in carrying out or executing the purposes and intent of
        this Agreement. However, nothing in this Agreement shall relieve the
        Escrow Agent from liability arising out of its own willful misconduct or
        gross negligence. The Escrow Agent's duties and obligations under this
        Agreement shall be entirely administrative and not discretionary. The
        Escrow Agent shall not be liable to any party to this Agreement or to
        any third-party as a result of any action or omission taken or made by
        the Escrow Agent in good faith. The parties to this Agreement will
        jointly and severally indemnify the Escrow Agent, hold the Escrow Agent
        harmless, and reimburse the Escrow Agent from, against and for, any and
        all liabilities, costs, fees and expenses (including reasonable
        attorney's fees) the Escrow Agent may suffer or incur by reason of its
        execution and performance of this Agreement. If any legal questions
        arise concerning the Escrow Agent's duties and obligations under this
        Agreement, then the Escrow Agent may consult with its counsel and rely
        without liability on written opinions given to it by its counsel.

        The Escrow Agent shall be protected in acting on any written notice,
        request, waiver, consent, authorization, or other paper or document
        which the Escrow Agent, in good faith, believes to be genuine and what
        it purports to be.

        If there is any disagreement between any of the parties to this
        Agreement, or between them or any other person, resulting in adverse
        claims or demands being made in connection with this Agreement, or if
        the Escrow Agent, in good faith, is in doubt as to what action it should
        take under this Agreement, then the Escrow Agent may, at its option,
        refuse to comply with any claims or demands on it or refuse to take any
        other action under this Agreement, so long as the disagreement continues
        or the doubt exists. In any such event, the Escrow Agent shall not be or
        become liable in any way or to any person for its failure or refusal to
        act and the Escrow Agent shall be entitled to continue to so refrain
        from acting until the dispute is resolved by the parties involved.

        National City Bank of Pennsylvania is acting solely as the Escrow Agent
        and is not a party to, nor has it reviewed or approved any agreement or
        matter of background related to this Agreement, other than this
        Agreement itself, and has assumed, without investigation, the authority
        of the individuals executing this Agreement to be so authorized on
        behalf of the party or parties involved.

        10. RESIGNATION OR REMOVAL OF ESCROW AGENT. The Escrow Agent may resign
        as such after giving thirty days' prior written notice to the other
        parties to this Agreement. Similarly, the Escrow Agent may be

                                       4


        removed and replaced after receiving thirty days' prior written notice
        from the other parties to this Agreement. In either event, the duties of
        the Escrow Agent shall terminate thirty days after the date of the
        notice (or as of an earlier date as may be mutually agreeable); and the
        Escrow Agent shall then deliver the balance of the Subscription Proceeds
        (and any interest paid or investment income earned thereon while held by
        the Escrow Agent in the escrow account) in its possession to a successor
        escrow agent appointed by the other parties to this Agreement as
        evidenced by a written notice filed with the Escrow Agent.

        If the other parties to this Agreement are unable to agree on a
        successor escrow agent or fail to appoint a successor escrow agent
        before the expiration of thirty days following the date of the notice of
        the Escrow Agent's resignation or removal, then the Escrow Agent may
        petition any court of competent jurisdiction for the appointment of a
        successor escrow agent or other appropriate relief. Any resulting
        appointment shall be binding on all of the parties to this Agreement.

        On acknowledgment by any successor escrow agent of the receipt of the
        then remaining balance of the Subscription Proceeds (and any interest
        paid or investment income earned thereon while held by the Escrow Agent
        in the escrow account), the Escrow Agent shall be fully released and
        relieved of all duties, responsibilities, and obligations under this
        Agreement.

11.     TERMINATION. This Agreement shall terminate and the Escrow Agent shall
        have no further obligation with respect to this Agreement after the
        distribution of all Subscription Proceeds (and any interest paid or
        investment income earned thereon while held by the Escrow Agent in the
        escrow account) as contemplated by this Agreement or on the written
        consent of all the parties to this Agreement.

12.     NOTICE. Any notices or instructions, or both, to be given under this
        Agreement shall be validly given if set forth in writing and mailed by
        certified mail, return receipt requested, or by facsimile with
        confirmation of receipt (originals to be followed in the mail), or by a
        nationally recognized overnight courier, as follows:

TO: _______________________________

    RE:  ATLAS AMERICA PUBLIC #15-2005 PROGRAM

Gentlemen:

        Atlas Resources, Inc. will be the Managing General Partner in a series
of up to three limited partnerships organized under the Delaware Revised Uniform
Limited Partnership Act:

        o       Atlas America Public #15-2006(B) L.P.; and

        o       Atlas America Public #15-2006(C) L.P.

which are referred to as the "Partnership" or the "Partnerships." The Units in
the Partnerships, which are referred to as the "Units," and the offering are
described in the Prospectus, copies of which have been furnished to you with
this Agreement.

        Our firm, Anthem Securities, Inc., which is referred to as the
"Dealer-Manager," has entered into a Dealer-Manager Agreement for sales in all
states, a copy of which has been furnished to you and is incorporated in this
Agreement by reference, with the Managing General Partner and the Partnerships
under which the Dealer-Manager has agreed to form a group of NASD member firms,
which are referred to as the "Selling Agents." The Selling Agents will obtain
subscriptions for Units in each Partnership in all states on a "best efforts"
basis under the Securities Act of 1933, as amended, which is referred to as the
"Act," and the provisions of the Prospectus.

        You are invited to become one of the Selling Agents on a non-exclusive
basis. By your acceptance below you agree to act in that capacity and to use
your best efforts, in accordance with the terms and conditions of this
Agreement, to solicit subscriptions for Units in each Partnership at the time
the Partnership is being offered as provided in Section 1 of the Dealer-Manager
Agreement in all states where you are duly registered or licensed as
broker/dealer.

1.      REPRESENTATIONS AND WARRANTIES OF SELLING AGENT. You represent and
        warrant to the Dealer-Manager that:

                are subject, with all requisite power and authority to enter
                into this Agreement and to carry out your obligations under this
                Agreement.

                                        1


        (b)     This Agreement when accepted and approved by you will be duly
                authorized, executed, and delivered by you and will be a valid
                and binding agreement on your part in accordance with its terms.

        (c)     The consummation of the transactions contemplated by this
                Agreement and the Prospectus will not result in the following:

                (i)     any breach of any of the terms or conditions of, or
                        constitute a default under your organizational
                        documents, bylaws, any indenture, agreement, or other
                        instrument to which you are a party or by which you are
                        bound; or

                (ii)    any violation of any order applicable to you of any
                        court, regulatory body or administrative agency having
                        jurisdiction over you or over your affiliates.

        (d)     You are duly registered under the provisions of the Securities
                Exchange Act of 1934, which is referred to as the "Act of 1934,"
                as a broker/dealer, and you are a member in good standing of the
                NASD. You are duly registered as a broker/dealer in the
                jurisdictions where you are required to be registered in order
                to carry out your obligations as contemplated by this Agreement
                and the Prospectus. You agree to maintain all the foregoing
                registrations in good standing throughout the term of the offer
                and sale of the Units, and you agree to comply with all statutes

                applies to your activities under this Agreement. Further, you

                                established by the program for participants
                                therein and such standards are fully disclosed
                                in the prospectus and are consistent with the
                                provisions of subparagraph (B) of this section.

                        (B)     In recommending to a participant the purchase,
                                sale or exchange of an interest in a direct

                                associated with a member shall:

                                (i)     have reasonable grounds to believe, on

                                        investment objectives, other
                                        investments, financial situation and
                                        needs, and any other information known
                                        by the member or associated person,
                                        that:

                                        2


                                        (a)  the participant is or will be in a
                                             financial position appropriate to
                                             enable him to realize to a
                                             significant extent the benefits
                                             described in the prospectus,
                                             including the tax benefits where
                                             they are a significant aspect of
                                             the program;

                                        (b)  the participant has a fair market

                                        was reached as to each participant.

                                        that such inquiry was conducted with due
                                        care;

                        (D)     Prior to executing a purchase transaction in a

                                associated with a member shall inform the

                Partner, or the Managing General Partner's special counsel, that
                the offer or sale of the Units:

                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
                contributions by the Dealer-Manager or Managing General Partner
                to a non-cash compensation arrangement between you and your
                associated persons, provided that the Dealer-Manager or Managing
                General Partner do not directly or indirectly participate in
                your organization of the permissible non-cash compensation
                arrangement.

                Additionally, the Dealer-Manager is entitled to receive from the
                Managing General Partner an up to .5% reimbursement of the
                Selling Agents' bona fide due diligence expenses per Unit.

                Subject to the terms and conditions set forth in this Agreement,
                including the Dealer-Manager's receipt from you of the
                documentation required of you in Section 1 of this Agreement,
                the Dealer-Manager agrees to pay you on Units sold by you and
                accepted by the Managing General Partner:

                (i)     a 7% Sales Commission, subject to the performance by you
                        of your obligations under Appendix I to this Agreement,
                        which is incorporated in this Agreement by reference;
                        and

                (ii)    up to a .5% reimbursement of your bona fide due
                        diligence expenses per Unit. With respect to the up to
                        .5% reimbursement of your bona fide due diligence
                        expenses, any bill presented by you to the
                        Dealer-Manager for reimbursement of costs associated
                        with your due diligence activities must be for actual
                        costs and may not include a profit margin. 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 you
                        must be based on your 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 your
                        compliance by requesting an itemized statement to
                        support the bill submitted by you. If such a due
                        diligence bill cannot be justified, any excess over
                        actual due diligence expenses that is paid is considered

        (b)     Notwithstanding anything in this Agreement to the contrary, you

                several, to which they may become subject under the Act, the Act
                of 1934, or otherwise insofar as the losses, claims, damages, or
                liabilities (or actions in respect thereof) arise out of or are
                based on your breach of any of your duties and obligations,
                representations, or warranties under the terms or provisions of
                this Agreement, and you shall reimburse them

                                        9


                for any legal or other expenses reasonably incurred in
                connection with investigating or defending the losses, claims,
                damages, liabilities, or actions.

        (b)     The Dealer-Manager shall indemnify and hold you harmless against
                any losses, claims, damages, or liabilities, joint or several,
                to which you may become subject under the Act, the Act of 1934,
                or otherwise insofar as the losses, claims, damages, or
                liabilities (or actions in respect thereof) arise out of or are
                based on the Dealer-Manager's breach of any of its duties and
                obligations, representations, or warranties under the terms or
                provisions of this Agreement, and the Dealer-Manager shall
                reimburse you for any legal or other expenses reasonably
                incurred in connection with investigating or defending the
                losses, claims, damages, liabilities, or actions.

        (c)     The foregoing indemnity agreements shall extend on the same
                terms and conditions to, and shall inure to the benefit of, each
                person, if any, who controls each indemnified party within the
                meaning of the Act.

        (d)     Promptly after receipt by an indemnified party of notice of the
                commencement of any action, the indemnified party shall, if a
                claim in respect of the action is to be made against the
                indemnifying party under this Section, notify the indemnifying
                party in writing of the commencement of the action; but the
                omission to promptly notify the indemnifying party shall not
                relieve the indemnifying party from any liability which it may
                have to the indemnified party. If any action is brought against
                an indemnified party, it shall notify the indemnifying party of
                the commencement of the action, and the indemnifying party shall
                be entitled to participate in, and, to the extent that it
                wishes, jointly with any other indemnifying party similarly
                notified, to assume the defense of the action, with counsel
                satisfactory to the indemnified and indemnifying parties. After
                the indemnified party has received notice from the agreed on
                counsel that the defense of the action under this paragraph has
                been assumed, the indemnifying party shall not be responsible
                for any legal or other expenses subsequently incurred by the
                indemnified party in connection with the defense of the action
                other than with respect to the agreed on counsel who assumed the
                defense of the action.

                Dealer-Manager, or any of its officers, directors or any person

        remedy or claim under or in respect of this Agreement. No purchaser of
        any of the Units from you shall be construed a successor or assign
        merely by reason of the purchase.

13.     RELATIONSHIP. You are not authorized to hold yourself out as agent of
        the Dealer-Manager, the Managing General Partner, a Partnership or any
        other Selling Agent. This Agreement shall not constitute you a partner
        of the Managing General Partner, the Dealer-Manager, a Partnership, any
        general partner of a Partnership, or any other Selling Agent, nor render
        the Managing General Partner, the Dealer-Manager, the Partnerships, any
        general partner of a Partnership, or any other Selling Agent, liable for
        any of your obligations.

14.     EFFECTIVE DATE. This Agreement is made effective between the parties as
        of the date accepted by you as indicated by your signature to this
        Agreement.

15.     ENTIRE AGREEMENT, WAIVER.

        (a)     This Agreement constitutes the entire agreement between the
                Dealer-Manager and you, and shall not be amended or modified in
                any way except by subsequent agreement executed in writing.
                Neither party to this Agreement shall be liable or bound to the
                other by any agreement except as specifically set forth in this
                Agreement.

        (b)     The Dealer-Manager and you may waive, but only in writing, any
                term, condition, or requirement under this Agreement that is
                intended for its benefit. However, any written waiver of any
                term or condition of this Agreement shall not operate as a
                waiver of any other breach of the term or condition of this
                Agreement.

        (c)     Also, any failure to enforce any provision of this Agreement
                shall not operate as a waiver of that provision or any other
                provision of this Agreement.

                by you.

18.     PRIVACY. The Dealer-Manager and you each acknowledge that certain
        information made available to the other under this Agreement may be
        deemed nonpublic personal information under the Gramm-Leach-Bliley Act,

        (a)     not to disclose or use the information except as required to
                carry out each party's respective duties under this Agreement or

        (b)     to establish and maintain procedures reasonably designed to
                assure the security and privacy of all the information; and

                ensuring compliance with the Privacy Laws to the extent
                applicable to either or both the Dealer-Manager and you.

19.     ANTI-MONEY LAUNDERING PROVISION. You represent and warrant to the
        Managing General Partner and the Dealer-Manager that you have in place
        and will maintain suitable and adequate "know your customer" policies

                      APPENDIX I TO SELLING AGENT AGREEMENT

In partial consideration for the payment to you, as Selling Agent, by the
Dealer-Manager of the Sales Commission as set forth in Section 2(a) of the
Selling Agent Agreement, you warrant, represent, covenant, and agree with the
Dealer-Manager that you, as Selling Agent, shall do the following:

        o       prominently and promptly announce your participation in the
                offering as Selling Agent to your registered representatives,
                whether by newsletter, e-mail, mail or otherwise, which
                announcement also shall advise your registered representatives
                to contact our Regional Marketing Director in whose territory
                the registered representative is located (the information
                concerning our Regional Marketing Directors has been provided to
                you by separate correspondence) with a copy of the announcement
                provided concurrently to the Dealer-Manager; and

        o       provide the Dealer-Manager with the names, telephone numbers,
                addresses and e-mail addresses of your registered
                representatives, which information shall be kept confidential by
                the Dealer-Manager and the Managing General Partner and shall
                not be used for any purpose other than the marketing of the
                offering as set forth in the Dealer-Manager Agreement and the
                Selling Agent Agreement. Further, you, as Selling Agent, agree
                that the Dealer-Manager and the Managing General Partner may
                directly contact your registered representatives, in person or
                otherwise, to:

                o       inform them of the offering;

                o       explain the merits and risks of the offering; and

                o       otherwise assist in your registered representatives'
                        efforts to solicit and sell Units.
