FORM OF SELLING DEALER AGREEMENT

(Selling Dealer Name and Address)

Ladies and Gentlemen:

ICON Oil & Gas Fund (the “Fund”) is a program comprised of up to three Delaware limited partnerships (ICON Oil & Gas Fund-A L.P. (“Partnership A”), ICON Oil & Gas Fund-B L.P. (“Partnership B”) and ICON Oil & Gas Fund-C L.P. (“Partnership C”)) that are offering, in the aggregate, (i) up to 16,000 investor general partner interests and (ii) up to 4,000 limited partner interests (collectively, the “Interests”) at a public offering price of $10,000.00 per Interest (subject in certain circumstances to discounts based upon the volume of Interests purchased and other exceptions) (for each, a “Partnership Offering” and, collectively, the “Offering”). The Interests and the terms upon which they are offered are more fully described in the prospectus for each partnership, in each case, as supplemented or amended at the time the related registration statement or post-effective amendment to the registration statement, as applicable, becomes effective (for each partnership, the applicable “Prospectus”), which is dated as of the date on which the Securities and Exchange Commission (“SEC”) declared the registration statement or post-effective amendment, as applicable (the “Registration Statement”), for the related Partnership Offering to be effective (in each case, the applicable “Effective Date”). The managing general partner for each partnership, ICON Oil & Gas GP, LLC (the “Managing General Partner”) may, at any time prior to the two-year anniversary of the date the Offering commences, increase the Offering to a maximum of up to 30,000 Interests; provided, however, that the Offering Period (as defined below) may not be extended in connection with such change.

Pursuant to the authority granted to us, ICON Securities Corp. (the “Dealer-Manager”), by each partnership in the dealer-manager agreement (the “Dealer-Manager Agreement”), we have selected your firm, and you are agreeing, to act as a selling dealer (a “Selling Dealer”) for the Offering, in accordance with the terms of this Agreement. In particular, by executing this Agreement you (1) represent to us and each partnership that your firm (a) is, and will remain at all times during which this Agreement is effective, a member in good standing of the Financial Industry Regulatory Authority, Inc. (“FINRA”), (b) is, and will remain at all times during which this Agreement is effective, duly qualified under the securities and other applicable laws of each jurisdiction checked on Exhibit A to this Agreement (as such shall be immediately amended by you, as necessary, to reflect any changes therein (i.e., additions thereto, or subtractions therefrom, of States)) and (c) will, at all times during which this Agreement is effective, offer Interests, directly and through your registered representatives, only to the residents of the States so designated and (2) agree to offer to sell, on a best efforts basis, Interests (a) directly to the general public, (b) in an aggregate amount not exceeding the total maximum offering of 20,000 Interests (or 30,000 if the Managing General Partner increases the Offering) (the “Maximum Offering”) and (c) to investors who satisfy the suitability standards set forth in the applicable Prospectus and as determined by your firm in accordance with FINRA’s Rules as in effect during the Offering Period (as defined below). All of such subscriptions, which shall be in the form of Exhibit C to the applicable Prospectus (the “Subscription Agreement”), are subject to acceptance by the applicable partnership and may be rejected in the sole discretion of the Managing General Partner.

In general, the “Offering Period” for the sale of Interests in each partnership will commence on the date of the applicable Prospectus (which is also the Effective Date for such Partnership Offering) and will terminate on the termination date for such Partnership Offering specified in the applicable Prospectus, unless (1) the Maximum Offering is completed earlier (e.g., through the sale of all Interests) or (2) such Partnership Offering is terminated earlier (with notice to you and the other Selling Dealers) at the election of the Managing General Partner, in its sole discretion (in each case, the applicable “Termination Date”). In addition to the foregoing general rules, each State must also authorize the sale of Interests to its residents (which State effective dates will be either the Effective Date for each partnership or as otherwise may be set forth on a “Blue-Sky Survey” issued, or to be issued, from time to time after the Effective Date for each partnership, by counsel to the Managing General Partner). Finally, because (i) some States separately authorize the offering of Interests in each of Partnership A, Partnership B and Partnership C immediately prior to each such Partnership Offering, rather than authorizing the offering of Interests in all three partnerships, collectively, prior to the Effective Date for Partnership A, and (ii) most States authorize the offering of Interests to their residents for a maximum of 12 months before requiring the re-registration of the offering or renewal of qualification of the Interests under their respective securities laws. Consequently, if you have not received an updated “Blue-Sky Survey” or applicable Prospectus prior to the beginning of each Partnership Offering and/or the first anniversary date, as applicable, of the Effective Date for each partnership, a request should be made for such updated materials to confirm the continued qualification of the applicable Partnership Offering in States in which you propose to offer Interests for sale).

Each date on which any investor is admitted to one of the partnerships in the Fund (thereby becoming an “Investor General Partner” and/or a “Limited Partner”) is hereinafter called a “Closing Date.”

Once executed by all parties, this Agreement will become effective only upon your receipt of notification (in the form of the initial “Blue-Sky Survey”) confirming that (1) the Registration Statement with respect to the Interests has become effective under the Securities Act of 1933, as amended (the “Act”), and (2) the Interests have been qualified for sale (or are exempt from such qualification requirements, if any) in at least one jurisdiction in which you and your registered representatives are duly qualified to offer to sell Interests (as indicated by you on Exhibit A).

Each partnership will accept subscriptions for Interests, subject to the Managing General Partner’s right to terminate the such Partnership Offering at any time and to reject any subscription in whole or in part, in its sole discretion. The acceptance of subscriptions is further subject to the following terms and conditions:

1. Appointment as Selling Dealer. We hereby authorize you to act as a Selling Dealer for each Partnership Offering during the Offering Period and, on a “best efforts” (and not “firm commitment”) basis only, to offer Interests directly to potential investors that (a) satisfy the investor suitability standards (i) set forth in the applicable Prospectus, (ii) provided under applicable State laws and (iii) provided in FINRA’s Rules and (b) are acceptable to each partnership (the “Eligible Investors”). As a Selling Dealer, you will act as an independent contractor and not as our agent or as agent for any partnership in connection with your solicitation of subscriptions for Interests and will therefore be responsible for assuring that each investor satisfies all such suitability requirements. You hereby agree that you will not make representations or give information not contained in (x) the applicable Prospectus or (y) any sales material that, if required, has been reviewed and approved by the appropriate regulatory agencies, which we have supplied to you for your use (as described in greater detail in Section 5 of this Agreement).

2. Subscriptions for Interests. You shall (a) find Eligible Investors for the Interests, (b) keep records of the basis for each determination by a member of, or person associated with, your firm of an investor’s suitability and (c) promptly forward each fully completed and executed copy of the Subscription Agreement, as signed by each investor and countersigned by a supervisory representative of your firm, together with the related subscription payment in the form of a check made payable to “UMB Bank, N.A., Escrow Agent for ICON O&G Fund-A,” “UMB Bank, N.A., Escrow Agent for ICON O&G Fund-B,” or “UMB Bank, N.A., Escrow Agent for ICON O&G Fund-C,” as applicable, pending receipt and acceptance by the Managing General Partner of subscriptions for 200 Interests in the applicable Partnership Offering and thereafter (except for residents of the Commonwealth of Pennsylvania and the State of Tennessee who must continue to make checks payable to the Escrow Account until subscriptions for 1,000 Interests have been received and accepted in the applicable Partnership Offering) in the form of a check made payable to “ICON O&G Fund-A.” “ICON O&G Fund-B” or “ICON O&G Fund-C,” as applicable, to:

Each Subscription Agreement and related subscription payment shall be forwarded by your firm to us at the foregoing address no later than noon of the next business day after receipt from your customer by any member of, or person associated with, your firm of such payment, unless such Subscription Agreement and payment are first forwarded to another of your offices for internal supervisory review (which shall take place within the aforementioned time period), in which event such other office shall complete its review and forward such Subscription Agreement and payment to the above address no later than noon of the next business day after its receipt thereof. Notwithstanding the foregoing, any investor’s check not properly completed as described above shall be promptly returned to such investor not later than the next business day following your receipt of such check. Each such subscription payment received and accepted by the Managing General Partner will be transmitted, as soon as practicable, but in any event by the end of the second business day following receipt thereof, to UMB Bank, N.A. (the “Escrow Agent”) for deposit in an interest-bearing bank account insured by the Federal Deposit Insurance Corporation, which shall be an escrow account in the name of Escrow Agent pending the receipt of subscriptions for an aggregate of 200 Interests in the applicable Partnership Offering (excluding those subscriptions received from residents of the Commonwealth of Pennsylvania and the State of Tennessee, for which an escrow account will be maintained until such time as subscriptions for 1,000 Interests have been received from investors in the applicable Partnership Offering in all jurisdictions) and thereafter will be deposited in a segregated subscription account maintained solely for such purpose by the applicable partnership. We will return directly to you any Subscription Agreement that is not accepted by the Managing General Partner together with the related subscription payment within two business days of our receipt of same for your prompt return of same to your customer. Unless and until an event requiring a refund occurs, an investor will have no right to withdraw his or her subscription payment from escrow. The Managing General Partner has reserved the unconditional right to refuse to accept, in whole or in part, any subscription and related payment and to refuse to accept as an investor any person for any reason whatsoever or no reason.

Unless subscriptions for at least 200 Interests are received and accepted by the Managing General Partner in the applicable Partnership Offering (excluding subscriptions for Interests from residents of the Commonwealth of Pennsylvania and the State of Tennessee) on or before the applicable Termination Date, the partnership will promptly refund all subscription payments received by it in full with interest earned thereon, if any, and without deduction for any expenses, and the applicable Partnership Offering shall thereupon terminate. Promptly after receiving and accepting subscriptions for 200 Interests in the applicable Partnership Offering (excluding subscriptions for Interests from residents of the Commonwealth of Pennsylvania and the State of Tennessee), the Managing General Partner will notify the Escrow Agent that Schedule A to the partnership’s limited partnership agreement (in each case, the applicable “Partnership Agreement”) has been amended to admit as Investor General Partners and/or Limited Partners investors (other than those who are residents of the Commonwealth of Pennsylvania and the State of Tennessee) for whom subscriptions have been accepted, and the Escrow Agent is to pay over promptly to the applicable partnership the amount of all of such investors’ subscription payments then on deposit (excluding those from residents of the Commonwealth of Pennsylvania and the State of Tennessee), including interest earned thereon. The date upon which such admission of Investor General Partners and/or Limited Partners shall occur is hereinafter called the “Initial Closing Date” for such partnership. Under regulations of the Commonwealth of Pennsylvania and the State of Tennessee, until subscriptions for 5% (or $10,000,000) of the maximum in the Offering have been received, the subscription payments of Pennsylvania and Tennessee residents must be held in escrow for each Partnership Offering. After subscriptions equaling $10,000,000 for the residents of all jurisdictions, including Pennsylvania and Tennessee, have been received in each Partnership Offering, all remaining subscriptions being held in escrow for such Partnership Offering will be released from escrow upon the next Closing Date and the applicable investors will be admitted to the applicable partnership as Investor General Partners and/or Limited Partners (in the manner described in the preceding sentence).

Following the Initial Closing Date for each partnership, the Managing General Partner will continue to accept subscriptions for additional Interests during the remainder of the Offering Period for such partnership and to admit as Investor General Partners and/or Limited Partners investors whose subscriptions are accepted. Such admissions will take place from time to time as shall be determined by the Managing General Partner, with the anticipation that Closing Dates subsequent to the Initial Closing Date will occur as frequently as daily, but not less frequently than monthly, following the Initial Closing Date and promptly following the end of the applicable Offering Period or earlier termination of the applicable Partnership Offering.

Subject to the volume discounts and other special circumstances described or otherwise provided in the “Plan of Distribution” section of the Prospectus, each partnership, by its acceptance of this Agreement, agrees to pay you sales commissions in an amount equal to 7.0% of the total purchase price of all Interests in such partnership sold through your efforts in the applicable Partnership Offering (the “Sales Commissions”), except for sales of Interests to (a) officers, employees and securities representatives of the Dealer-Manager, the Managing General Partner, their affiliates and each Selling Dealer (the “Affiliated Members”), who may purchase Interests for a net price of $9,300.00 per Interest and as to which no Sales Commissions are payable, and (b) investors by registered investment advisers affiliated with you who do not charge a commission in connection with an investment in Interests (the “RIA Members”), who may purchase Interests for a net price of $9,300.00 per Interest and as to which no Sales Commissions are payable. Purchases of Interests by Affiliated Members and RIA Members shall be for their own accounts, for investment purposes only and not with a view toward resale or other distribution.

All such compensation will be paid by the applicable partnership within 30 days after each applicable Closing Date in respect of subscriptions submitted by investors who were admitted to such partnership on such Closing Date. No compensation will be paid with respect to subscriptions (or portions thereof) that have been rejected by the Managing General Partner, or in the event the minimum offering for 200 Interests for the applicable partnership is not successfully completed.

Sales Commissions with respect to Interests actually sold by you or your registered representatives will be due and payable to you within 30 days of each Closing Date on which the investors for such Interests are admitted as Limited Partners.

3. Termination of Agreement. The provisions of this Agreement relating to each Partnership Offering shall terminate as to the applicable partnership upon the completion of the Offering Period for such partnership or earlier termination of the Partnership Offering, and may be terminated by you or us as specified in Section 10 of this Agreement, subject to the survival of all provisions hereof which by their nature are intended to survive termination of this Agreement.

4. Limitations on Payments. You agree that neither you nor any salesperson or registered representative under your control shall, directly or indirectly, pay or award any finder’s fees, commissions or other compensation to any person engaged by a potential investor for investment advice as an inducement to such advisor to advise the purchase of Interests; provided, however, that this provision shall not prohibit the normal sales commission payable to any properly licensed person for selling Interests. In addition, you agree not to receive any rebates or give-up or participate in any reciprocal business arrangements (other than the securities distribution arrangements specified in each Prospectus) that would violate any restriction on a partnership contained in the applicable Prospectus.

5. Supplemental Sales Material. Supplemental sales materials shall be categorized as either: (a) “Broker/Dealer Use Only” educational materials, which shall be defined for purposes of this Agreement as materials prepared for or by a partnership for the sole purpose of educating you in your preparation to solicit the sale of Interests in the Offering and shall not be used by you with members of the general investing public and, to the extent required, have been submitted to, reviewed by and approved by the appropriate regulatory agencies (“B/D Use Only Materials”) or (b) Investor sales materials, which shall be defined as materials prepared for or by a partnership that, to the extent required, have been submitted to, reviewed by and approved by FINRA, the SEC and any other appropriate regulatory agencies (“Investor Sales Materials” and, together with B/D Use Only Materials, “Supplemental Sales Materials”).

You acknowledge and agree that only Investor Sales Materials may be used by you with members of the general investing public. You agree that you will not use any Supplemental Sales Materials other than each Prospectus (including, inter alia, transmittal letters, underwriting memoranda, summary descriptions, graphics, supplemental exhibits, media advertising, charts, pictures, written scripts or outlines), whether prepared to solicit sales to prospective investors or for the exclusive use of you and your personnel, except as supplied by a partnership and described under the caption “Supplemental Sales Literature” in such Prospectus, or otherwise specifically described in a written advice from a partnership authorizing the type and manner of use. The use of any other Supplemental Sales Materials is expressly prohibited except to the extent specified in any such written advice.

6. Right To Sell. Notwithstanding any information furnished or any action taken by us in that connection, we shall have no obligation or liability with respect to the registration or qualification of the Interests in any jurisdiction or the qualification or right of you or any Selling Dealer to sell or advertise them therein.

7. Limited Obligations. Nothing herein contained shall constitute the Selling Dealers as a partnership, association or other separate entity or partners with us, or with each other, but you shall be responsible for your share of any liability or expense based upon any claim to the contrary. We shall not have any liability to you, except for obligations expressly assumed in this Agreement and any liabilities under the Act, and no other obligations on our part shall be implied hereby or inferred herefrom.

(a) We will indemnify and hold you harmless in the manner and to the extent specified in Section 4.05 of each Partnership Agreement (the terms of which are incorporated herein by reference) against any losses, claims, damages or liabilities, joint or several, to which you may become subject under the Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of any material fact contained in any applicable Registration Statement, Prospectus, or amendment or supplement thereto relating to the applicable partnership, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading; and we will reimburse you for any legal or other expenses reasonably incurred by you in connection with investigating or defending any such action or claim.

Notwithstanding the foregoing provisions of this Section 7(a), we will not be liable in any case to the extent that it is determined that you were at fault in connection with any loss, claim, damage or liability or to the extent that any such loss, claim, damage or liability arises out of or is based upon (i) an untrue statement or an alleged untrue statement or omission or alleged omission made in any applicable Registration Statement, Prospectus or amendment or supplement thereto in reliance upon and in conformity with written information furnished to us by you expressly for use therein, (ii) the offer or sale by you of an Interest to a person who fails to meet the standards regarding suitability under any applicable federal, State or FINRA laws, rules and regulations or (iii) breach of your representations, warranties or obligations under this Agreement.

The indemnity agreement in this subsection (a) shall be in addition to any liability which we may otherwise have and shall extend, upon the same terms and conditions, to each person, if any, who controls you within the meaning of the Act.

(b) You agree to indemnify us and each partnership and hold us and each partnership harmless against any losses, claims, damages or liabilities to which we or such partnership(s) may become subject, under the Act or otherwise, (i) insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of any material fact contained in any applicable Registration Statement, Prospectus, or any amendment or supplement thereto, or arise out of or are based upon the omission or the alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading, provided that such untrue statement or alleged untrue statement or omission or alleged omission was made in any applicable Registration Statement, Prospectus or any amendment or supplement to any applicable Prospectus or Registration Statement in reliance upon and in conformity with written information furnished to us by you for use therein or (ii) for any breach by you of the provisions of this Agreement; and to reimburse us and each partnership, as applicable, for any legal or other expenses reasonably incurred by us or such partnership(s) in connection with investigating or defending any such action or claim. You agree to obtain and keep in force insurance in such amounts and types as is customary and reasonable in order to satisfy any indemnification obligations arising under this subsection (b).

The indemnity agreement in subsection (b) shall be in addition to any liability which you may otherwise have and shall extend, upon the same terms and conditions, to each officer and director of the undersigned, and to each person, if any, who controls the undersigned within the meaning of the Act.

(c) Promptly after receipt by an indemnified party under subsection (a) or (b) above of notice of the commencement of any action, if a claim in respect thereof is to be made against the indemnifying party under such subsection, such indemnified party shall notify the indemnifying party in writing of the commencement thereof; but the omission to so notify the indemnifying party shall not relieve it from any liability which it may have to any indemnified party otherwise than under such subsection. In case any such action shall be brought against any indemnified party and it shall notify the indemnifying party of the commencement thereof, the indemnifying party shall be entitled to participate in, and, to the extent that it shall wish, to jointly participate with any other indemnifying party, similarly notified, in the defense thereof with the indemnified party. The indemnifying party shall pay all legal fees and expenses of the indemnified party in the defense of such claims or actions; provided, however, that the indemnifying party shall not be obliged to pay legal expenses and fees to more than one law firm in connection with the defense of similar claims arising out of the same alleged acts or omissions giving rise to such claims, notwithstanding that such actions or claims are alleged or brought by one or more parties against one or more than one indemnified party. In case such claims or actions are alleged or brought against more than one indemnified party, then the indemnifying party shall be obliged to reimburse the expenses and fees of only one law firm, selected by a majority of the indemnified parties against which such action is brought. In the event the majority of such indemnified parties are unable to agree on a law firm for which expenses or fees will be reimbursed by the indemnifying party, then payments shall be made to the first law firm of record representing an indemnified party against the action or claim. Such law firm shall be paid only to the extent of the services performed by such law firm and no reimbursement shall be payable to such law firm on account of legal services performed by another law firm. Notwithstanding anything contained herein to the contrary, an indemnified party may not settle or compromise any action brought against such indemnified party without the prior written consent of the indemnifying party.

(d) The provisions of this Section 7 shall remain in full force and effect after the termination of this Agreement.

Notwithstanding the foregoing, no Selling Dealer shall be indemnified for any losses, liabilities or expenses arising from or out of any alleged violation of federal or State securities laws, unless (i) there shall have been a successful adjudication on the merits of each count involving alleged securities law violations as to the particular indemnitee and a court shall have approved indemnification and reimbursement of actual litigation costs, or (ii) such claims shall have been dismissed with prejudice on the merits, and indemnification and reimbursement of actual litigation costs shall have been approved by a court of competent jurisdiction as to the particular indemnitee, or (iii) a court of competent jurisdiction shall have approved a settlement of the claims against a particular indemnitee and found that indemnification and reimbursement of the settlement and related costs should be made. In any claim for indemnification for federal or State securities law violations, any Selling Dealer seeking indemnification shall place before the court the position of the SEC with respect to the issue of indemnification for securities law violations.

8. Representations, Warranties and Covenants of Selling Dealer.

You represent, warrant and covenant as of the date this Agreement is executed on behalf of your firm and as of the date any Subscription Agreement is forwarded to us, the Managing General Partner or any of the partnerships as follows:

(a) Qualification of Selling Dealer and its Representatives. You represent, warrant and covenant that you are, and during the Offering Period will continue to be, (i) a member in good standing of FINRA and (ii) registered as a securities broker-dealer in those jurisdictions wherein members of, or persons associated with, your firm will offer or sell the Interests. You also represent, warrant and covenant that, during the Offering Period, you will only permit members of, or persons associated with, your firm to offer or sell Interests if such persons are duly registered or licensed to sell direct participation program investments by, and in good standing with, FINRA and those jurisdictions wherein they will offer or sell Interests. You hereby certify that neither your firm nor any member of your firm has been subject to a fine, a consent decree or suspension of your or their licenses or registrations within the last three (3) years for violation of federal or State securities rules, laws or regulations. You also hereby certify that you will promptly advise the Dealer-Manager of any pending, threatened or current civil or administrative proceedings during the Offering Period involving alleged violations of such rules, laws or regulations.

(b) Investor Suitability and Minimum Investment. You further represent, warrant and covenant that no member of, or person associated with, your firm shall offer or sell Interests in any jurisdiction except to investors who satisfy the investor suitability and minimum investment requirements under the most restrictive of the following: (i) applicable provisions of the applicable Prospectus, (ii) the laws of the jurisdiction of which such investor is a resident, and (iii) FINRA rules and regulations and FINRA Rule 2310, in particular. Specifically, you agree to ensure that, in recommending the purchase or sale of Interests to an investor, each member of, or person associated with, your firm shall have reasonable grounds (as required by Rule 2310(b)(2)(B)(i) of the FINRA Rules) to believe, on the basis of information obtained from the investor (and thereafter maintained in the manner and for the period provided in such FINRA Rules) concerning his or her age, investment objectives, other investments, financial situation and needs, and any other information known to such member of, or person associated with, your firm, that (A) the investor is or will be in a financial position appropriate to enable him or her to realize to a significant extent the benefits described in the applicable Prospectus, including the tax benefits to the extent they are a significant aspect of each partnership; (B) the investor has a fair market net worth sufficient to sustain the risks inherent in an investment in Interests in the amount proposed, including complete loss, and lack of liquidity, of such investment; and (C) an investment in Interests is suitable in type and amount for such investor. You further represent, warrant and covenant that you will: (x) require each member of, or person associated with, your firm to make diligent inquiry as to the suitability and appropriateness of an investment in Interests from each proposed investor, (y) retain in your records for a period equal to the longer of (A) six years from the date of the applicable sale of Interests or (B) five years from the end of the applicable Offering Period (or such longer period as is provided in Section 9 hereof), and (z) make available to us and each partnership, upon request (and upon your firm’s receipt of an appropriate document subpoena from one of the following, to representatives of the SEC, FINRA and applicable State securities administrators) documents disclosing the basis upon which the determination as to suitability was reached as to each purchaser of Interests pursuant to a subscription solicited by your firm, whether such records relate to accounts which have been closed, accounts which are currently maintained, or accounts hereafter established. You shall not purchase any Interests for a discretionary account without obtaining the prior written approval of your customer and his or her signature on a Subscription Agreement.

(c) Due Diligence; Adequate Disclosure. By signing below and signing each Subscription Agreement, you hereby acknowledge (or reaffirm, in the latter case) that, prior to entering into this Agreement, your firm satisfied itself that it has reasonable grounds to believe, based upon information and other relevant materials made available to you by each partnership, that all material facts are adequately and accurately disclosed in each Prospectus and provide a basis for evaluation of an investment in the Interests (as is provided in Rule 2310(b)(3)(A), (B) and (C) of the FINRA Rules). In determining the adequacy of the disclosed facts, you shall obtain information on material facts relating at a minimum to the following, if relevant in view of the nature of each partnership: (i) items of compensation; (ii) physical properties; (iii) tax aspects; (iv) financial stability and experience of the Managing General Partner; (v) each partnership’s conflicts and risk factors; and (vi) appraisals and other pertinent reports. You further acknowledge that you did not, and may not, rely upon the investigation conducted by us in our capacity as Dealer-Manager (because of our affiliation with the Managing General Partner and each partnership) or by any other Selling Dealers, unless in the latter case all of the conditions set forth in FINRA Rule 2310(b)(3)(C) have been met.

(d) Compliance with FINRA Rules. You also hereby agree, represent and covenant that you will require each member of, or person associated with, your firm to inform any prospective purchaser of Interests, prior to his or her subscription for Interests, of all pertinent facts relating to the liquidity and marketability of an investment in Interests during the term of the investment (as provided in FINRA Rule 2310(b)(3)(D)). You also hereby agree to fully comply with all pertinent sections of Article III of FINRA’s Rules of Fair Practice, including, without limitation, Sections 8, 24, and 36 thereof.

(e) Delivery of the Applicable Prospectus in Connection with the Sale of Interests. You hereby represent, covenant and agree that no representative of your firm shall sell, and your firm shall not endorse and forward any Subscription Agreement to signify the completion of a subscription for, any Interests unless, in connection therewith, the proposed purchaser of such Interests has received a current copy of the applicable Prospectus at or prior to the time that such person has signed his or her Subscription Agreement. Your firm acknowledges and agrees that such proposed purchaser shall not be admitted to the applicable partnership and Interests issued until the later of (i) the next succeeding Closing Date or (ii) five business days after the date such proposed purchaser received a copy of the applicable Prospectus (which shall be determined by the Managing General Partner by the date on which such proposed purchaser signed the Subscription Agreement).

(f) Compliance with Rule 15c2-8 of the Securities Exchange Act of 1934, as amended. You hereby (i) represent that neither you nor any person associated with your firm solicited customers’ orders for Interests prior to the Effective Date; (ii) represent and agree to take all reasonable steps to make available a copy of the applicable final Prospectus relating to the Interests to each person associated with your firm who is expected, after the applicable Effective Date, to solicit customer orders for Interests prior to the making of any such solicitation by such associated persons; and (iii) agree that neither you, nor any person associated with your firm, will furnish Prospectuses to any person in any State (e.g. in any State (A) listed as not cleared on the “Blue-Sky Survey” of the Dealer-Manager or (B) in which your firm or any person associated with your firm who solicits offers to buy or offers to sell Interests is not currently registered); provided, however, that this provision is not to be construed to relieve you from complying with the requirements of Section 5(b)(1) and (2) of the Act. You hereby acknowledge that Prospectuses shall not be furnished by you or any person associated with your firm to any prospective investor while the applicable Registration Statement is subject to an examination, proceeding or stop order pursuant to Section 8 of the Act.

(g) Compliance with Title III of PATRIOT Act. With respect to your customers or any customers solicited by persons associated with your firm that purchase Interests, you hereby represent and agree to comply with relevant provisions applicable to securities broker-dealers of Title III of the Uniting and Strengthening America by Providing Appropriate Tools Required to Intercept and Obstruct Terrorism Act of 2001, Pub. L. No. 107-56, 115 Stat. 272 (2001) (the “PATRIOT Act”), as well as FINRA Rule 3310 setting forth minimum standards for Anti-Money Laundering (“AML”) Programs of broker-dealers. These minimum standards require you to have implemented a written AML Program reasonably designed to (i) detect traces of suspicious financial transactions, (ii) achieve compliance with the Bank Secrecy Act regulations, (iii) provide for independent testing, (iv) designate an AML Compliance Officer, and (v) provide for ongoing training. Title III of the PATRIOT Act, 31 U.S.C. §§ 5311, et seq., is referred to as the International Money Laundering Abatement and Anti-Terrorist Financing Act of 2001 (the “Money Laundering Abatement Act”). Among other applicable requirements under the Money Laundering Abatement Act, you agree to comply with Section 312 regarding due diligence requirements, Section 313 regarding correspondent account prohibitions, Section 314 regarding financial institution cooperation, Section 319(b) regarding domestic and foreign bank records production, Section 326 regarding customer identification standards (as described in greater detail in Section 8(i) of this Agreement), Section 352 regarding anti-money laundering compliance program components, and Section 356 regarding suspicious activity reporting requirements.

(h) Compliance with Privacy Laws. You hereby represent, warrant and covenant that you and any person associated with your firm (i) will abide by and comply with (A) the privacy standards and requirements of the Gramm-Leach-Bliley Act of 1999 (“GLB Act”), (B) the privacy standards and requirements of any other applicable federal or State law, and (C) your own internal privacy policies and procedures, each as may be amended from time to time; (ii) will refrain from the use or disclosure of nonpublic personal information (as defined under the GLB Act) of all customers who have opted out of such disclosures except as necessary to service the customers or as otherwise necessary or required by applicable law; and (iii) will be responsible for determining which customers have opted out of the disclosure of nonpublic personal information by periodically reviewing and, if necessary, retrieving a list of such customers (the “List”) to identify customers that have exercised their opt-out rights. In the event you use or disclose nonpublic personal information of any customer for purposes other than servicing the customer, or as otherwise required by applicable law, you will consult the List to determine whether the affected customer has exercised his or her opt-out rights.
