                         DISTRIBUTION SUPPORT AGREEMENT

         THIS DISTRIBUTION SUPPORT AGREEMENT (this "Agreement") is made as of
February 2, 2000 between Atlas Pipeline Partners, L.P. (the "MLP"), Atlas
Pipeline Partners GP, LLC (the "General Partner"), and Atlas America, Inc.
("Atlas"), Resource Energy, Inc. ("REI") and Viking Resources Corporation
("Viking").

         WHEREAS, the General Partner is the general partner of the MLP;

         WHEREAS, the MLP has completed a public offering (the "Offering") of
common units of limited partnership interest (the "Common Units"); and

         WHEREAS, it is a condition to the completion of the Offering that the
parties enter into this Agreement.

         NOW, THEREFORE, in consideration of the premises and the mutual
covenants and agreements herein set forth, and intending to be legally bound,
the parties agree as follows:

         1. Defined Terms. Unless otherwise defined herein, capitalized terms
shall have the meanings set forth in the First Amended and Restated Agreement of
Limited Partnership of the MLP (the "Partnership Agreement") except that, as
used herein, "Common Units" refers only to the Common Units issued and
outstanding as a result of the Offering and those issued and outstanding as a
result of the exercise by the Underwriters of the Over-Allotment Option.

         2. MLP's Limited Capital Call Right. For a period of three years ending
on February 2, 2003 (the "Call Period"), the General Partner agrees to
contribute, on a quarterly basis, to the capital of the MLP, within five
business days of its receipt of the MLP's notice (which notice shall
simultaneously be sent to Atlas, REI and Viking), an amount equal to (a) the
difference between (i) the amount of Available Cash determined in compliance
with the Partnership Agreement and (ii) the product of the Minimum Quarterly
Distribution for the Quarter ended immediately prior to such notice multiplied
by the number of Common Units; provided, however, that the General Partner's
obligation hereunder shall be prorated for partial Quarters included in the Call
Period. The General Partner shall be entitled to repayment of any amounts so
contributed as set forth in the Partnership Agreement. The MLP's notice shall
not be given to the General Partner prior to the the determination of the
Available Cash for that Quarter.

         3. Letter of Credit. Atlas, REI and Viking have obtained, and shall
maintain in accordance with the provisions hereof, an irrevocable letter of
credit for the benefit of the MLP, from a commercial bank in an amount necessary
to secure the General Partner's performance hereunder (the "Letter of Credit").
Unless otherwise permitted hereby, the Letter of Credit shall expire no earlier
than June 1, 2003.

                  (a) Increase on Amount of Letter of Credit. In the event the
Underwriters exercise the Over-Allotment Option, Atlas, REI and Viking agree,
effective not later than the date on which the Over-Allotment Option Common
Units are sold, to cause the amount of the Letter of Credit to be increased by
an amount equal to the product of (i) $0.42 multiplied by (ii) the number of
Quarters remaining in the Call Period (prorated for partial quarters) multiplied
by (iii) the number of over-allotment Common Units.

                  (b) Reduction in Amount of Letter of Credit. The amount
available under the Letter of Credit shall be adjusted from time to time as
appropriate to reflect the maximum amount of capital the General Partner may be
required to contribute to the MLP hereunder. The Letter of Credit shall provide
that it be subject to partial draws and shall be reduced each Quarter after the
determination of Available Cash, upon the earliest of (i) a draw on the Letter
of Credit; (ii) the General Partner's making the required capital contribution
hereunder for such Quarter; or (iii) written notice to the General Partner,
Atlas, REI and Viking from the MLP that no capital contribution is required for
such Quarter.

         4. Termination. This Agreement, and the parties rights and duties
hereunder, shall terminate in the event the General Partner is removed as
general partner of the MLP under circumstances where Cause does not exist and
Units held by the General Partner and its Affiliates are not voted in favor of
that removal.

         5. Miscellaneous.

                  (a) Choice of Law; Submission to Jurisdiction. This Agreement
shall be subject to and governed by the laws of the Commonwealth of
Pennsylvania, excluding any conflicts-of-law rule or principle that might refer
the construction or interpretation of this Agreement to the laws of another
state. Each party hereby submits to the jurisdiction of the state and federal
courts in the Commonwealth of Pennsylvania and to venue, respectively, in
Philadelphia, Pennsylvania and the Eastern District of Pennsylvania.

                  (b) Entire Agreement. This Agreement constitutes the entire
agreement of the parties relating to the matters contained herein, superseding
all prior contracts or agreements, whether oral or written.

                  (c) Effect of Waiver or Consent. No waiver or consent, express
or implied, by any party to or of any breach or default by any party in the
performance by such party of its obligations hereunder shall be deemed or
construed to be a consent or waiver to or of any other breach or default in the
performance by such party of the same or any other obligations of such party
hereunder. Failure on the part of a party to complain of any act of the other
party or to declare the other party in default, irrespective of how long such
failure continues, shall not constitute a waiver by such party of its rights
hereunder until the applicable statute of limitations period has run.

                  (d) Amendment or Modification. This Agreement may be amended
or modified from time to time only by the written agreement of all the parties
hereto; provided, however, that the MLP may not, without the prior approval of
the Conflicts Committee, agree to any amendment or modification of this
Agreement or the Letter of Credit that adversely affect the holders of Common
Units.

                  (e) Assignment. No party shall have the right to assign its
rights or obligations under this Agreement without the consent of the other
party.

                  (f) Counterparts. This Agreement may be executed in any number
of counterparts with the same effect as if all signatory parties had signed the
same document. All counterparts shall be construed together and shall constitute
one and the same instrument.

                  (g) Severability. If any provision of this Agreement or the
application thereof to any party or circumstance is determined by a court of
competent jurisdiction to be invalid, void or unenforceable, the remaining
provisions hereof, or the application of such provision to circumstances other
than those as to which it has been held invalid or unenforceable, shall remain
in full force and effect and shall in no way be affected, impaired or
invalidated thereby, so long as the economic or legal substance of the
transactions contemplated hereby is not affected in any manner materially
adverse to any party. Upon such determination, the parties shall negotiate in
good faith in an effort to agree upon a suitable and equitable substitute
provision to effect the original intent of the parties.

                  (h) Further Assurances. In connection with this Agreement and
all transactions contemplated by this Agreement, each signatory party hereto
agrees to execute and deliver such additional documents and instruments and to
perform such additional acts as may be necessary or appropriate to effectuate,
carry out and perform all of the terms, provisions and conditions of this
Agreement and all such transactions.

                  (i) Third Party Beneficiaries. The provisions of this
Agreement are enforceable solely by the parties to it, and no Common Unit holder
or its assignee or any other person shall have the right, separate and apart
from the MLP, to enforce any provision of this Agreement or to compel any party
to this Agreement to comply with its terms.

                  (j) Headings. The headings throughout this Agreement are
inserted for reference purposes only, and are not to be construed or taken into
account in interpreting the terms and provisions of any Article, nor to be
