                           SOLICITING DEALER AGREEMENT

                    Mewbourne Energy 06-07 Drilling Programs

                               ____________, 2006

Gentlemen:

     Mewbourne Development Corporation, a Delaware corporation ("MD"), is or
proposes to be the sole managing general partner (in such capacity the "Managing
Partner") in a series of two limited partnerships (the "Partnerships") formed
pursuant to the Delaware Revised Uniform Limited Partnership Act (the "Delaware
Act"). MD intends to name the Partnerships as follows: Mewbourne Energy Partners
06-A, L.P. and Mewbourne Energy Partners 07-A, L.P. Each Partnership will
participate in a program, governed by a Drilling Program Agreement (the "Program
Agreement") among Mewbourne Oil Company, a Delaware corporation ("MOC"), MD and
such Partnership, the primary purpose of which will be to drill Developmental
Wells (as such term is defined in the Prospectus referred to below).

     On behalf of the Partnership and MD, a Registration Statement on Form S-1
(Registration No. 333-____________) dated _____________, relating to the offer
and sale of the Interests (hereinafter defined) was filed with the Securities
and Exchange Commission (the "Commission") under the Securities Act of 1933 (the
"Act"). On ______________, MD filed with the Commission on behalf of the
Partnerships Amendment No. 1 to the Registration Statement. The Registration
Statement was declared effective by the Commission on ___________. MD, the
Partnerships and the Interests are described in the Prospectus dated ___________
(the "Prospectus") that forms a part of the Registration Statement. As used in
this Soliciting Dealer Agreement (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 MD 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 herein will have the meanings set forth in the Prospectus.

     MD desires to raise a minimum of $5,000,000 and a maximum of $50,000,000 in
capital for each Partnership by the sale of up to an aggregate of $100,000,000
of limited partner interests (the "Limited Partner Interests") and general
partner interests (the "General Partner Interests") in the Partnerships (the
Limited Partner Interests and the General Partner Interests are collectively
referred to as the "Interests"). The Interests will be offered in $1,000
increments, with a minimum purchase of twenty Interests ($20,000).

     Mewbourne Securities, Inc., a Texas corporation (the "Dealer Manager"), has
entered into a Dealer Manager Agreement with the Managing Partner under which
the Dealer Manager is appointed the exclusive agent of the Managing Partner and
of the Partnerships to form a group of National Association of Securities
Dealers, Inc. member firms who will solicit subscribers for the purchase of
Interests.

     The following are the terms on which the Managing Partner, on behalf of the
Partnership, and the Dealer Manager appoint you and you agree to such
appointment to solicit subscribers for the purchase of Interests:

     Section 1. Appointment as Soliciting Dealer. On the basis of the
representations, warranties and covenants contained in this Agreement, but
subject to the terms and conditions set forth herein, you are hereby appointed
to serve as a soliciting dealer ("Soliciting Dealer") during the Offering Period
(as defined below) for Interests in both Partnerships for the purpose of finding
subscribers for the Interests through a public offering, at the price of $1,000
per Interest, with a minimum subscription of twenty Interests ($20,000), as
described in the

Prospectus. The "Offering Period" (as such term is used in this Agreement) for
Interests in Mewbourne Energy Partners 06-A, L.P. will commence on or about the
date on which the Registration Statement is declared effective and will end no
later than December 31, 2006 unless the Managing Partner accelerates or delays
such termination date. The Offering Period for Interests in Mewbourne Energy
Partners 07-A, L.P. will commence in 2007 and will end no later than December
31, 2007. MD has the right in its sole and absolute discretion to terminate the
offering of Interests and end the Offering Period at any time. You hereby accept
appointment as a Soliciting Dealer and agree on the terms and conditions set
forth in this Agreement to use your reasonable efforts to solicit subscriptions
for the Interests during each Offering Period and until the earlier of (i) the
termination of the Offering Period or (ii) the Closing (as hereinafter defined)
with respect to that Partnership. Neither your acceptance of that appointment
nor this Agreement shall constitute you and MD or a Partnership as an
association, partnership, unincorporated business or other separate entity. If
an offering for Interests in a Partnership is commenced and subscriptions funds
of $5,000,000 or more are not received by the termination of that Partnership's
Offering Period with respect to Interests in that Partnership, all subscription
funds received by the termination of such Offering Period with respect to
Interests in that Partnership shall be returned in full to the subscribers,
together with any interest earned thereon, if any (as provided in the
Prospectus), and this Agreement as to that Partnership will terminate without
obligation on your part or on the part of MD, except that (a) you will promptly,
upon notice, transmit to MD any sales commissions and marketing fees received by
you pursuant to Section 6(b) hereof, and (b) the indemnification and
contribution provisions of Section 9 hereof shall continue after such
termination of this Agreement. In the event that you violate the terms,
conditions, agreements or warranties herein, the Managing Partner or the Dealer
Manager, in their sole and absolute discretion, may terminate this Agreement.

     Section 2. Representations and Warranties of MD and the Dealer Manager. MD,
in its individual capacity and in its capacity as Managing Partner, and the
Dealer Manager, jointly and severally, hereby represent and warrant to you that:

     (a) In the name and on behalf of the Partnerships, MD has prepared and
filed with the Commission the Registration Statement (including the Prospectus)

you.

     (b) On the Closing Date (as hereinafter defined) for the sale of Interests
in a Partnership, the related Partnership will be a limited partnership duly
formed and validly existing under the laws of the State of Delaware and will be
duly qualified or registered as a foreign limited partnership or otherwise
qualified as a limited partnership in each jurisdiction in which the nature of
the activities conducted by it or the nature of the assets owned by it make such
qualification necessary (except where the failure to so qualify or register
would not have a material adverse effect on the Partnership or the rights or
liabilities of its General or Limited Partners). In addition, such Partnership
shall have full and adequate partnership power and partnership authority to
enter into and perform this Agreement and the related Program Agreement and to
own its properties and to conduct its business as proposed in the Prospectus.

     (c) MD is, and at all times through the Closing Date will be, a
corporation, validly existing and in good standing under the laws of the State
of Delaware with full and adequate corporate power and corporate authority to
enter into and perform this Agreement and the Agreement of Partnership and to
own its properties and to conduct its business as presently conducted and as
proposed in the Prospectus to be conducted.

     (d) Each subscriber for Limited Partner Interests will become a Limited
Partner of the Partnership entitled to all the rights of a Limited Partner under
the Agreement of Partnership for the Partnership and the Delaware Act upon (i)
payment of the consideration for those Limited Partner Interests specified in
that subscriber's Subscription Agreement and (ii) acceptance by the Managing
Partner of that subscriber as a Limited Partner. Each subscriber for General
Partnership Interests will become a General Partner of the Partnership entitled
to all the rights of a General Partner under the Agreement of Partnership for
the Partnership and the Delaware Act upon (i) payment of the consideration for

for as contemplated by the Prospectus, will represent validly authorized and
duly issued Interests and those Interests will conform in all material respects
to the statements relating thereto contained in the Prospectus, including the
Form of Agreement of Partnership attached as Exhibit A thereto.

     (e) This Agreement has been duly and validly authorized by MD and the
Dealer Manager. MD and the Dealer Manager have duly executed and delivered this
Agreement, which constitutes a valid and binding agreement of MD and the Dealer
Manager enforceable in accordance with its terms (except to the extent that the

limited under federal securities laws or to the extent the enforceability of
this Agreement may be limited by bankruptcy, insolvency, reorganization,
moratorium or similar laws affecting the right of creditors generally).

     (f) The Commission has not issued any order preventing or suspending the
use of the Prospectus.

     (g) From the time the Registration Statement initially became effective
through the Closing Date, the Registration Statement and the Prospectus did and
will comply in all material respects with the provisions of the Act, and neither
the Registration Statement and the Prospectus nor any Sales Literature (as
hereinafter defined) contains or will contain any untrue statement of a material
fact or omit to state a material fact necessary in order to make the statements
therein, in light of the circumstances under which they were made, not
misleading; provided, however, that the representations and warranties contained
in this subsection (g) shall not apply to statements in, or omissions from, the
Registration Statement, the Prospectus or the Sales Literature based upon and in
conformity with information furnished to MD or a Partnership by you in writing
specifically for use in the Registration Statement, the Prospectus or Sales
Literature.

     (h) Based upon the opinion of Vinson & Elkins L.L.P., counsel for MD, and
subject to the assumptions and representations expressed therein, under existing
federal income tax laws and regulations the Partnership, upon its formation,
will be classified as a partnership for federal income tax purposes. A
Partnership, at the related Closing, will be classified as a partnership for
federal income tax purposes, and at all times subsequent hereto, MD will use its
best efforts to maintain the status of the Partnership as a partnership for
federal income tax purposes.

     (i) Except as disclosed in the Prospectus, there is no litigation or
governmental proceeding pending or, to the best knowledge of MD, threatened that
involves the offering of the Interests or any of the properties or businesses of
MD that would, if adversely decided, materially and adversely affect
(financially or otherwise) the operation of the business of the Partnership, MD
or the offering.

     (j) MD is not in violation of the Agreements of Partnership or in material
default in the performance of any obligation, agreement or condition contained
in any agreement by which a Partnership is bound. The execution and delivery of
this Agreement and the Agreements of Partnership, the fulfillment of the terms
set forth herein and therein and the consummation of the transactions
contemplated herein and therein and in the Prospectus will not conflict with or
constitute a breach of or material default under the Agreements of Partnership
or under the certificate of incorporation or bylaws of MD or under any other
agreement, indenture or instrument by which a Partnership or MD is bound or, to
the best knowledge of MD, any law, rule, regulation, order or decree of any
court or any governmental body or administrative agency applicable to MD or a
Partnership.

     (k) The financial information (including without limitation the balance
sheets and any accompanying notes and schedules) presented in the Prospectus
concerning MD presents fairly MD's financial position as of the dates thereof in
accordance with generally accepted accounting principles, and there has been,
and through the Closing Date shall be, no material adverse change in its
financial condition since the date of that information.

     (l) There has been no material adverse change in the condition, business or
properties of MD, financial or otherwise, from that on the latest dates as of
which such condition, business or properties are set forth in the Prospectus,
except as referred to therein, and such properties and business substantially
conform and shall at the

the descriptions thereof contained in the Prospectus.

     (m) MD will timely apply, on behalf of the Partnership, to the Internal
Revenue Service for a tax shelter registration number and, if such a number is
received, will furnish such number to the General and Limited Partners of such
Partnership within a reasonable time after their admission to the Partnership or

preceded or must be accompanied by the Prospectus. You agree not to discuss any
specific oil and gas prospect or to refer to any such oil and gas prospect in

     (e) You will make offers to sell Interests to, sell to or solicit offers to
subscribe for Interests from persons in only those states or other jurisdictions

                         2730. SECURITIES TAKEN IN TRADE

          (a) A member engaged in a fixed price offering, who purchases or
     arranges the purchase of securities taken in trade, shall purchase the
     securities at a fair market price at the time of purchase or shall act as
     agent in the sale of such securities and charge a normal commission
     therefor.

          (b) When used in this Rule:

               (1) the term "taken in trade" means the purchase by a member as
          principal, or as agent for the account of another, of a security from
          a customer pursuant to an agreement or understanding that the customer
          purchase securities from the member which are part of a fixed price
          offering.

               (2) the term "fair market price" means a price not higher than
          the price at which the securities would be purchased from the customer
          or from a similarly situated customer in the ordinary course of
          business by a dealer in such securities in transactions of similar
          size and having similar characteristics but not involving a security
          taken in trade.

               (3) the term "normal commission" means an amount of commission
          which the member would normally charge to that customer or a similarly
          situated customer in the ordinary course of business in transactions
          of similar size and having similar characteristics but not involving a
          security taken in trade.

          (c) For purposes of this Rule a member shall be:

               (1) deemed, with respect to securities other than common stocks,
          to have taken such securities in trade at a fair market price when the
          price paid is not higher than the highest independent bid for the
          securities at the time of purchase, if such bid quotations for the
          securities are readily available.

               (2) presumed, with respect to common stocks, to have taken such
          common stocks in trade at a fair market price when the price paid is
          not higher than the highest independent bid for the securities at the
          time of purchase, if such bid quotations for the securities are
          readily available.

               (3) presumed to have taken a security in trade at a price higher
          than a fair market price when the price paid is higher than the lowest
          independent offer for the securities at the time of purchase, if such
          offer quotations for the securities are readily available.

          (d) A member, in connection with every transaction subject to this
     Rule, shall with respect to:

               (1) common stocks, which are traded on a national securities
          exchange or for which quotations are entered in an automated quotation
          system, obtain the necessary bid and offer quotations from the
          national securities exchange or from the automated quotation system;
          and

               (2) other securities and common stocks not included in
          subparagraph (1) above, obtain directly or with the assistance of an
          independent agent bid and offer quotations from two or more
          independent dealers relating to the securities to be taken in trade
          or, if such quotations are not readily available, exercise its best
          efforts to obtain such quotations with respect to securities having
          similar characteristics and of similar quality as those to be taken in
          trade.

          (e) A member who purchases a security taken in trade shall keep or
     cause to be kept adequate records to demonstrate compliance with this Rule
     and shall preserve the records for at least 24 months after the
     transaction. If an independent agent is used for the purpose of obtaining
     quotations, the member must request the agent to identify the dealers from
     whom the quotations were obtained and the time and date they were obtained
     or request the agent to keep and maintain for at least 24 months a record
     containing such information.

            2740. SELLING CONCESSIONS, DISCOUNTS AND OTHER ALLOWANCES

          In connection with the sale of securities which are part of a fixed
     price offering:

          (a) A member may not grant or receive selling concessions, discounts,
     or other allowances except as consideration for services rendered in
     distribution and may not grant such concessions, discounts or other
     allowances to anyone other than a broker or dealer actually engaged in the
     investment banking or securities business; provided, however, that nothing
     in this Rule shall prevent any member from (1) selling any such securities
     to any person, or account managed by any person, to whom it has provided or
     will provide bona fide research, if the stated public offering price for
     such securities is paid by the purchaser; or (2) selling any such
     securities owned by him to any person at any net price which may be fixed
     by him unless prevented therefrom by agreement.

          (b) The term "bona fide research," when used in this Rule, means
     advice, rendered either directly or through publications or writings, as to
     the value of securities, the advisability of investing in, purchasing, or
     selling securities, and the availability of securities or purchasers or
     sellers of securities, or analyses and reports concerning issuers,
     industries, securities, economic factors and trends, portfolio strategy,
     and performance of accounts; provided, however, that investment management
     or investment discretionary services are not bona fide research.

          (c) A member who grants a selling concession, discount or other
     allowance to another person shall obtain a written agreement from that
     person that he will comply with the provisions of this Rule, and a member
     who grants such selling concession, discount or other allowance to a
     nonmember broker or dealer in a foreign country shall also obtain from such
     broker or dealer a written agreement to comply, as though such broker or
     dealer were a member, with the provisions of Rules 2730 and 2750 and to
     comply with Rule 2420 as that Rule applies to a nonmember broker/dealer in
     a foreign country.

          (d) A member who receives an order from any person designating another
     broker or dealer to receive credit for the sale shall, within 30 days after
     the end of each calendar quarter, file reports with the Association
     containing the following information with respect to each fixed price
     offering which terminated during that calendar quarter: the name of the
     person making the designation; the identity of the brokers or dealers
     designated; the identity and amount of securities for which each broker or
     dealer was designated; the date of the commencement and termination of the
     offering and such other information as the Association shall deem
     pertinent.

          (e) A member who is designated by its customer for the sale of
     securities shall keep, and maintain for a period of 24 months, records in
     such form and manner to show the followi
