RE: ATLAS RESOURCES PUBLIC #18-2008 PROGRAM

Gentlemen:

The undersigned, Atlas Resources, Inc., which is referred to as the “Managing General Partner,” on behalf of Atlas Resources Public #18-2008 Program, which is referred to as the “Program,” is a series of up to three limited partnerships formed under the Delaware Revised Uniform Limited Partnership Act as described below. These limited partnerships are sometimes referred to in this Agreement in the singular as a “Partnership” or in the plural as “Partnerships.” The Managing General Partner on behalf of the Partnerships hereby confirms its agreement with you, as Dealer-Manager, as follows:

1.	Description of Program and Units.

(a)

The Managing General Partner, a Pennsylvania corporation, will be the sole managing general partner of up to three limited partnerships which will be named as follows:

(i)

Atlas Resources Public #18-2008(A) L.P.;

(ii)

Atlas Resources Public #18-2009(B) L.P.; and

(iii)

Atlas Resources Public #18-2008(C) L.P.

On behalf of the Program and the Partnerships, a Registration Statement on Form S-1 (Registration No. 333-________) relating to the offer and sale of the limited partner and investor general partner interests in the Partnerships, which are referred to as the “Units,” was filed on ___________, 2008 with the Securities and Exchange Commission (the “Commission”) under the Securities Act of 1933, as amended, which is referred to as the “Act.” The Registration Statement has been declared effective by the Commission and the Partnerships and the Units are described in the Prospectus that forms a part of the Registration Statement. 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 by the Managing General Partner 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.

Terms defined in the Prospectus and not otherwise defined in this Agreement shall have the meanings set forth in the Prospectus.

(b)

The Units will be sold at a price of $10,000 per Unit subject to the discounts for certain investors set forth in Section 4(c) of this Agreement for certain investors. Subject to the receipt and acceptance by the Managing General Partner of the minimum subscription proceeds of $2,000,000 in a Partnership by its Offering Termination Date for each Partnership as described in the Prospectus (the “Offering Termination Date”), the Managing General Partner may break escrow and use the subscription proceeds for the Partnership’s drilling activities, which is referred to as the “Initial Closing Date.” Also, the maximum subscription proceeds of all of the Partnerships, in the aggregate, must not exceed the registered amount of $600 million.

The Managing General Partner will notify you and the “Selling Agents,” as defined below, of the Initial Closing Date and Offering Termination Date for each Partnership.

2.	Representations, Warranties and Agreements of the Managing General Partner. The Managing General Partner represents and warrants to and agrees with you that:

(a)

The Partnerships composing the Program have a currently effective Registration Statement on Form S-1, including a final Prospectus, for the registration of the Units under the Act as described in Section 1 of this Agreement.

(b)

The Managing General Partner shall provide to you for delivery to all offerees and purchasers and their representatives the information and documents that the Managing General Partner deems appropriate to comply with the Act and applicable state securities acts, which are referred to as the “Blue Sky” laws.

(c)

The Units when issued will be duly authorized and validly issued as set forth in the Agreement of Limited Partnership of each Partnership, which is referred to as the “Partnership Agreement,” the form of which is included as Exhibit (A) to the Prospectus, and subject only to the rights and obligations set forth in the Partnership Agreement or imposed by the laws of the state of formation of each Partnership or of any jurisdiction to the laws of which each Partnership is subject.

(d)

Each Partnership was duly formed under the laws of the State of Delaware and is validly existing as a limited partnership in good standing under the laws of Delaware with full power and authority to own its properties and conduct its business as described in the Prospectus. Each Partnership will be qualified to do business as a limited partnership or similar entity offering limited liability in those jurisdictions where the Managing General Partner deems the qualification necessary to assure limited liability of the limited partners.

This Agreement, when executed by you, will be a valid and binding agreement of each Partnership and the Managing General Partner, duly authorized, executed and delivered by them and enforceable in accordance with its terms except as may be limited by the effect of bankruptcy, insolvency, moratorium, preferential or fraudulent conveyance or other laws or equitable principles relating to or affecting the rights of creditors generally, general principles of equity, and public policy relating to claims for indemnification for securities laws violations.

(e)

The Prospectus, as supplemented or amended, does not contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary in order to make the statements in the Prospectus, in the light of the circumstances under which they are made, not misleading.

3.	Grant of Authority to the Dealer-Manager.

(a)

Based on the representations and warranties contained in this Agreement, and subject to the terms and conditions set forth in this Agreement, the Managing General Partner appoints you as the Dealer-Manager for the Partnerships and gives you the exclusive right to solicit subscriptions for the Units on a “best efforts” basis in all states during the offering period for each Partnership as described in the Prospectus.

(b)

You agree to use your best efforts to effect sales of the Units and to form and manage a selling group composed of soliciting broker/dealers, which are referred to as the “Selling Agents,” each of which shall be a member of the Financial Industry Regulatory Authority, which is referred to as “FINRA,” (formerly known as National Association of Securities Dealers, Inc., or NASD) and shall enter into a “Selling Agent Agreement” in substantially the form attached to this Agreement as Exhibit “B.”

(c)

The Managing General Partner shall have three business days after the receipt of an executed Selling Agent Agreement to refuse that Selling Agent’s participation.

4.	Compensation and Fees.

(a)

As Dealer-Manager you shall receive from the Managing General Partner the following compensation, based on each Unit sold to investors in a Partnership whose subscriptions for Units are accepted by the Managing General Partner:

(i)

a 2.5% Dealer-Manager fee;

(ii)

a 7% Sales Commission; and

(iii)

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

(b)

All of the up to .5% reimbursement of the Selling Agents’ bona fide due diligence expenses shall be reallowed to the Selling Agents, and all or a portion of the 7% Sales Commission shall be reallowed to the Selling Agents as described in the Selling Agent Agreement with each Selling Agent. A portion of the balance of the 2.5% Dealer-Manager fee may be reallowed to the wholesalers as wholesaling fees for subscriptions obtained through their efforts. However, you may reduce the wholesaling fees by any reimbursements made by the Managing General Partner or the Partnership for expenses which are received by the wholesalers in connection with the Program or expenses which are owed by the wholesalers to the Managing General Partner or the Partnership in connection with the Program. Also, you may use a portion of your Dealer-Manager fee to pay for permissible non-cash compensation. Under Rule 2810 of the FINRA 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:

(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.

In no event shall a selling agent receive non-cash compensation and a marketing fee if it represents more than .5% per unit.

You shall retain any of the 7% Sales Commission and the 2.5% Dealer-Manager fee not reallowed to the Selling Agents or the wholesalers.

You are responsible for ensuring that all non-cash compensation arrangements comply with FINRA Conduct Rule 2810. For example, payments or reimbursements by you or the Managing General Partner may be made in connection with meetings held by you 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:

(i)

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;

(ii)

the location of the training and education meeting is appropriate to the purpose of the meeting as defined in FINRA Conduct Rule 2810;

(iii)

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

(iv)

the payment or reimbursement by you or the Managing General Partner is not conditioned by you or the Managing General Partner on the achievement of a sales target; and

(v)

the recordkeeping requirements are met.

(c)

Notwithstanding the foregoing:

(i)

the Managing General Partner, its officers, directors, and affiliates, and investors who buy Units through the officers and directors of the Managing General Partner may subscribe to Units for a subscription price reduced by the 2.5% Dealer-Manager fee, the 7% Sales Commission and the up to .5% reimbursement of the Selling Agents’ bona fide due diligence expenses, which shall not be paid to you; and

(ii)

registered investment advisors and their clients and Selling Agents and their registered representatives and principals may subscribe to Units for a subscription price reduced by the 7% Sales Commission, which shall not be paid to you, although their subscription price shall not be reduced by the 2.5% Dealer-Manager fee and the up to .5% reimbursement of the Selling Agents’ bona fide due diligence expenses, which shall be paid to you.

No more than 5% of the total Units sold in the Partnerships shall be sold, in the aggregate, with the discounts described above.

(d)

Pending receipt and acceptance by the Managing General Partner of the minimum subscription proceeds of $2,000,000 in each Partnership, excluding any optional subscription of the Managing General Partner and its Affiliates and the subscription discounts set forth in Section 4(c) of this Agreement, all proceeds received by you from the sale of Units in each Partnership shall be held in a separate interest bearing escrow account as provided in Section 15 of this Agreement.

Unless at least the minimum subscription proceeds of $2,000,000 as described above are received on or before the Offering Termination Date of a Partnership as described in Section 1 of this Agreement, the offering of Units in that Partnership shall be terminated, in which event:

(i)

the 2.5% Dealer-Manager fee, the 7% Sales Commission and the up to .5% reimbursement of the Selling Agents’ bona fide due diligence expenses set forth in Section 4(a) of this Agreement shall not be payable to you;

(ii)

all funds advanced by subscribers shall be returned to them with interest earned; and

(iii)

you shall deliver a termination letter in the form provided to you by the Managing General Partner to each of the subscribers and to each of the offerees previously solicited by you and the Selling Agents in connection with the offering of the Units.

(e)

Except as otherwise provided below, the fees, reimbursements, and Sales Commissions set forth in Section 4(a) of this Agreement shall be paid to you within five business days after the following:

(i)

at least the minimum subscription proceeds of $2,000,000 as described above have been received by the respective Partnership and accepted by the respective Partnership; and

(ii)

the subscription proceeds have been released from the escrow account to the respective Partnership.

You shall reallow to the Selling Agents and the wholesalers their respective fees, reimbursements, and Sales Commissions as set forth in Section 4(b) of this Agreement.

Thereafter, your fees, reimbursements and Sales Commissions shall be paid to you and shall be reallowed to the Selling Agents and wholesalers as described above approximately every two weeks until the Offering Termination Date for the respective Partnership. All your remaining fees, reimbursements, and Sales Commissions shall be paid to you by the Managing General Partner no later than fourteen business days after the Offering Termination Date for the respective Partnership.

5.	Covenants of the Managing General Partner. The Managing General Partner covenants and agrees that:

(a)

The Managing General Partner shall deliver to you ample copies of the Prospectus and all amendments or supplements to the 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 required to be stated therein or 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 jurisdiction over you or 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 or dealer, and you are a member in good standing of FINRA. You are duly registered as a broker/dealer in the states 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 in each Partnership, and you agree to comply with all statutes and other requirements applicable to you as a broker/dealer under those registrations.

(e)

Pursuant to your appointment as Dealer-Manager, you shall use your best efforts to exercise the supervision and control that you deem necessary and appropriate to the activities of you and the Selling Agents to comply with all the provisions of the Act, insofar as the Act applies to your and their activities under this Agreement. Further, you and the Selling Agents shall not engage in any activity which would cause the offer and/or sale of the Units not to comply with the Act, the Act of 1934, the applicable rules and regulations of the Commission, the applicable state securities laws and regulations, this Agreement, and the FINRA Conduct Rules including Rules 2420, 2730, 2740, 2750, and Rule 2810(b)(2) and (b)(3), which provide as follows:

Sec. (b)(2)

(i)

the prospective purchasers meet the suitability requirements set forth in the Prospectus, the Subscription Agreement, and this Agreement; and

(ii)

the prospective purchasers properly complete and execute the Subscription Agreement, which has been provided as Exhibit (I-B) to the Partnership Agreement, Exhibit (A) of the Prospectus, together with any additional forms provided in any supplement or amendment to the Prospectus, or otherwise provided to you by the Managing 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)

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

(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 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.

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.

(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.

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.

(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.

EXHIBIT “A”

ATLAS RESOURCES PUBLIC #18-2008(A) L.P.

ESCROW AGREEMENT

THIS AGREEMENT is made to be effective as of ____________, 2008, by and among Atlas Resources, LLC, a Pennsylvania limited liability company (the “Managing General Partner”), Anthem Securities, Inc., a Pennsylvania corporation (“Anthem”), the “Dealer-Manager,” Atlas Resources Public #18-2008(A) L.P., a Delaware limited partnership (the “Partnership”) and National City Bank, 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 59,000 investor general partner interests and up to 1,000 limited partner interests in the Partnership (the “Units”).

WHEREAS, each Investor will be required to pay his subscription in full on subscribing by check or wire (the “Subscription Proceeds”).

WHEREAS, the cost per Unit will be $10,000 subject to certain discounts of up to 10% ($1,000 per Unit) for sales to the Managing General Partner, its officers, directors and affiliates, registered investment advisors and their clients, Selling Agents and their registered representatives and principals, and investors who buy Units through the officers and directors of the Managing General Partner. Larger subscriptions are permitted in $1,000 increments.

WHEREAS, the Managing General Partner and Anthem have executed an agreement (“Anthem Dealer-Manager Agreement”) under which Anthem will solicit subscriptions for Units in all states on a “best efforts” “all or none” basis for Subscription Proceeds of $2,000,000 and on a “best efforts” basis for the remaining Units on behalf of the Managing General Partner and the Partnership and under which Anthem has been authorized to select certain members in good standing of the Financial Industry Regulatory Authority (“FINRA”), previously known as the National Association of Securities Dealers, Inc., to participate in the offering of the Units (“Selling Agents”).

WHEREAS, the Anthem Dealer-Manager Agreement, the “Dealer-Manager Agreement,” provides for compensation to the Dealer-Manager to participate in the offering of the Units, subject to the discounts set forth above for certain Investors, which compensation includes, but is not limited to, for each Unit sold:

a 2.5% Dealer-Manager fee;

a 7% sales commission; and

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

all or a portion of which will be reallowed to the Selling Agents and wholesalers.

WHEREAS, under the terms of the Dealer-Manager Agreement the Subscription Proceeds are required to be held in escrow subject to the receipt and acceptance by the Managing General Partner of the minimum Subscription Proceeds of $2,000,000, excluding any optional subscription by the Managing General Partner, its officers, directors, and Affiliates.

WHEREAS, the Units may also be offered and sold by the officers and directors of the Managing General Partner without receiving a sales commission or other compensation on their sales.

WHEREAS, no subscriptions to the Partnership will be accepted after the “Offering Termination Date,” which is the first to occur of either:

receipt of the maximum Subscription Proceeds of $600,000,000; or

December 31, 2008.

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:

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.

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 and mailing address and wire transfer account number information, if any. In this regard, the Selling Agents shall promptly transmit any and all checks received by them from Investors and the original executed Subscription Agreement to the Dealer-Manager by noon of the next business day following receipt of the check by them. By noon of the next business day following the Dealer-Manager’s receipt of the check and the original executed subscription documents, the Dealer-Manager shall transmit the check and a copy of the executed Subscription Agreement and mailing address to the Escrow Agent. In the event of a wire transfer, the wire transferred funds will be sent directly from the subscriber to the Escrow Agent and the Subscription Agreement, along with the wire transfer account number information will be sent as set forth above.

Payment for each subscription for Units shall be in the form of a check or wire made payable to the Escrow Agent as follows: “National City Bank, Escrow Agent, Atlas Resources Public #18-2008(A) L.P.,” pending receipt of the Partnership’s minimum Subscription Proceeds of $2,000,000.

Investment of Subscription Proceeds. The Subscription Proceeds in the escrow account (“Escrow Account”) 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 and income 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 signed written Distribution of Subscription Proceeds 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;

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 (“Initial Distribution”). 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 after a three 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, upon written request by 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.

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 Distribution of Subscription Proceeds Notice described in Paragraph 4 of this Agreement in good order, 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 in writing, and the Escrow Agent promptly shall distribute to each Investor, for which Escrow Agent has (1) a copy of the Investor’s Subscription Agreement with mailing address and wire transfer information, (2) received Subscription Proceeds, and (3) become Distributable Subscription Proceeds, 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 such Subscription Proceeds relating to the subscription have been deposited with the Escrow Agent into the Escrow Account and the 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 three day period from the date of deposit, 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 the Investor’s Subscription Agreement with mailing address and wire transfer information, (2) received Subscription Proceeds, and (3) become Distributable Subscription Proceeds, 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.

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, disbursements and advances (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.

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 and signed 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.

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 and shall under no circumstances be deemed a fiduciary for any of the parties to this Agreement. 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, damages, fees and expenses (including reasonable attorney’s fees) (collectively, “Losses”) the Escrow Agent may suffer or incur by reason of its execution and performance of this Agreement (including, but not limited to, Losses incurred by the Escrow Agent in connection with its successful defense, in whole or in part, of any claim of gross negligence or willful misconduct on its part). Escrow Agent shall not be liable for any action taken and believed by it to be authorized or within the rights or powers conferred upon it by this Agreement, and may consult with counsel of its own choice and shall have full and complete authorization and protection for any action taken or suffered by it hereunder in good faith and in accordance with the opinion of such counsel. The foregoing indemnities in this paragraph will survive the resignation or substitution of the Escrow Agent or the termination of this Agreement).

The Escrow Agent shall be protected in acting or refraining from acting upon any written notice, instruction, request, waiver, consent, authorization, or other paper or document furnished to it hereunder for which the Escrow Agent, in good faith, believes to be genuine, to have been signed or presented by the proper party or parties, and to be 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 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. This Agreement sets forth all matters pertinent to the duties contemplated hereunder, and no additional obligations of the Escrow Agent shall be inferred from the terms of this Agreement or any other agreement.

10.

Resignation or Removal of Escrow Agent/Merger. 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 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.

In the event that the bank acting as Escrow Agent merges or consolidates with another bank or sells or transfers all or substantially all of its assets or trust business, then the successor or resulting bank shall be the Escrow Agent hereunder without the necessity of further action or the execution of any document, so long as such successor or resulting bank meets the requirements of a successor escrow agent hereunder.

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.

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:

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 FINRA 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.

2.	Commissions.

(a)

Subject to the receipt of the minimum required subscription proceeds of $2,000,000 as described in Section 4(d) of the Dealer-Manager Agreement, and the discounts set forth in Section 4(c) of the Dealer-Manager Agreement for sales to the Managing General Partner, its officers, directors and affiliates, registered investment advisors and their clients, Selling Agents and their registered representatives and principals, and investors who buy Units through the officers or directors of the Managing General Partner, the Dealer-Manager is entitled to receive from the Managing General Partner a 7% Sales Commission and a 2.5% Dealer-Manager Fee, based on the aggregate amount of all Unit subscriptions to a Partnership secured by the Dealer-Manager or the selling group formed by the Dealer-Manager and accepted by the Managing General Partner.

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 by FINRA to be undisclosed underwriting compensation and is required to be included within the 10% compensation guideline under FINRA Conduct Rule 2810, and reflected on your books and records. Notwithstanding, if you provide an itemized bill in excess of .5% then the excess over .5% will not be included within the 10% compensation guideline, but instead the 4.5% organization and offering cost guideline of FINRA Conduct Rule 2810.

(iii)

In addition, the Dealer-Manager or Managing General Partner may make certain non-cash compensation arrangements of up to .5% per Unit with you or your registered representatives. The permissible non-cash compensation will be paid for training and education meetings, gifts that do not exceed $100 per year and are not preconditioned on the achievement of a sales target, 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 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. The Dealer-Manager is responsible for ensuring that all non-cash compensation arrangements comply with the restrictions on non-cash compensation in connection with direct participation programs as set forth in FINRA Conduct Rule 2810. For example, if the Managing General Partner or Dealer-Manager pays or reimburses you in connection with meetings held by the Managing General Partner or Dealer-Manager for the purpose of training or education of your registered representatives, then the following conditions must be met:

(A)

your registered representative must obtain your prior approval to attend the meeting and attendance by your registered representatives must not be conditioned by you on the achievement of a sales target;

(B)

the location of the training and education meeting must be appropriate to the purpose of the meeting, as defined in FINRA Conduct Rule 2810;

(C)

the payment or reimbursement must not be applied to the expenses of guests of the registered representative;

(D)

the payment or reimbursement by the Managing General Partner or Dealer-Manager must not be conditioned by the Managing General Partner or Dealer-Manager on the achievement of a sales target; and

(E)

the appropriate records must be maintained.

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.

[Also, the Dealer-Manager may pay a marketing fee of up to ________ if you provide marketing support as set forth in Appendix I, but in no event shall you receive non-cash compensation and the marketing fee if it represents more than .5% per unit.]

(iv)

Your sales commissions which are owed to you as set forth above shall be paid to you within seven business days after the Dealer-Manager has received the related amounts owed to it under the Dealer-Manager Agreement, which the Dealer-Manager is entitled to receive within five business days after the conditions described in Section 4(e) of the Dealer-Manager Agreement are satisfied and approximately every two weeks thereafter until the respective Partnership’s Offering Termination Date, which is described in Section 1 of the Dealer-Manager Agreement. The balance of your sales commissions and the reimbursements which are owed to you as set forth above shall be paid to you within seven business days after the Dealer-Manager has received the related amounts owed to it under the Dealer-Manager Agreement, which the Dealer-Manager is entitled to receive within fourteen business days after the respective Partnership’s Offering Termination Date.

(b)

Notwithstanding anything in this Agreement to the contrary, you agree to waive payment of your compensation and reimbursements which are owed to you as set forth above until the Dealer-Manager is in receipt of the related amounts owed to it under the Dealer-Manager Agreement, and the Dealer-Manager’s liability to pay your compensation and reimbursements under this Agreement shall be limited solely to the proceeds of the related amounts owed to it under the Dealer-Manager Agreement.

(c)

As provided in Section 4(d) of the Dealer-Manager Agreement, a Partnership shall not begin operations unless it receives subscription proceeds for at least $2,000,000 by its respective Offering Termination Date. If this amount is not secured by the respective Partnership’s Offering Termination Date, then nothing shall be payable to you for the respective Partnership and all funds advanced by subscribers for Units in the respective Partnership shall be returned to them with interest earned, if any.

Blue Sky Qualification. 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. On application to the Dealer-Manager you will be informed 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.

Notwithstanding the foregoing, the Dealer-Manager, the Partnerships, and the Managing General Partner have not assumed and will not assume any obligation or responsibility as to your right to act as a broker/dealer with respect to the Units in any state or jurisdiction.

4.	Expense of Sale. The expenses in connection with the offer and sale of the Units shall be payable as set forth below.

(a)

The Dealer-Manager shall pay all expenses incident to the performance of its obligations under this Agreement, including the fees and expenses of its attorneys and accountants, even if the offering of any or all of the Partnerships is not successfully completed.

(b)

You shall pay all expenses incident to the performance of your obligations under this Agreement, including the fees and expenses of your own counsel and accountants, even if the offering of any or all of the Partnerships is not successfully completed.

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

You shall indemnify and hold harmless the Dealer-Manager, 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 breach of any of your duties and obligations, representations, or warranties under the terms or provisions of this Agreement, and you 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 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)

(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.
