                                   Article 6.
                             MEASUREMENT AND TESTING

         6.1. Measurement Equipment. Measurement of Shipper's Gas shall take
place at the Receipt Points. Shipper will install, or cause to be installed, at
or near the Receipt Points, orifice meters or other measuring equipment
necessary in Gatherer's judgment to accurately measure the volumes of Shipper's
Gas being delivered into the Gathering System to the extent such meters or other
measuring equipment have not been installed as of the date of this Agreement.
Such measuring equipment shall be comparable to the measuring equipment of other
parties delivering gas into the Gathering System. Shipper shall be responsible
for, and bear the cost of, acquiring, installing, maintaining and operating such
measurement equipment.

         6.2. Chart Integration. Gatherer shall be responsible for reading the
meters at the Receipt Points. Gatherer shall furnish, install, remove, and
integrate all recording charts used in such meters in accordance with Gatherer's
standard practices.

         6.3. Delivery Points. The measurement of and tests for quality of
Shipper's Gas redelivered at the Delivery Points shall be governed by and
determined in accordance with the requirements of the receiving pipeline at each
Delivery Point.

         6.4. Unit of Volume. The unit of volume for purposes of measurement
shall be one (1) cubic foot of gas at a temperature base of sixty degrees
(60(Degree)) Fahrenheit and at a pressure base of fourteen and seventy-three
one-hundredths (14.73) psia.

         6.5. Testing Procedures. Shipper shall follow the meter calibrations
schedule established by Gatherer for each meter on the Gathering System. Such
calibrations shall occur at least once every twelve (12) months but not more
frequently than once every six (6) months. No testing, calibration, or
adjustment of a meter or related equipment shall be performed without Gatherer
first being given five (5) days' notice thereof and having the opportunity to be
present.

                                        6
<PAGE>

         6.6. Meter Inaccuracy. If, at any time, any meter is found to be out of
service or registering inaccurately in any percentage, it shall be adjusted at
once by Shipper to read accurately within the limits prescribed by the meter's
manufacturer. If such equipment is out of service or inaccurate by an amount
exceeding three percent (3%) of a reading corresponding to the average flow rate
for the period since the last test, the previous readings shall be corrected for
the period that the meter is known to be inaccurate, or, if not known, a period
of one-half (1/2) the elapsed time since the last test. The volume of Shipper's
Gas delivered during such period shall be estimated by Gatherer either (i) by
using the data recorded by any check measuring equipment if installed and
accurately registered, (ii) by correcting the error if the percentage of error
is ascertainable by calibration, test, or mechanical calculation or, if neither
such method is feasible, (iii) by estimating the quantity delivered based upon
deliveries under similar conditions during a period when the equipment
registered accurately. No volume correction shall be made for metering
inaccuracies of three percent (3%) or less.

         6.7. Meter Testing. If Gatherer requests to have any meter tested, then
Shipper shall have the meter tested in the presence of and to the satisfaction
of Gatherer. If the meter tested proves to be accurate within plus or minus
three percent (3%) at its normal operating range, then the cost of testing and
recalibrating the meter shall be borne by Gatherer. Shipper will schedule all
required tests within ten (10) days of a request by Gatherer. Shipper will
notify Gatherer at least five (5) working days prior to the test of the date,
time, and location of such test.

         6.8. Books and Records. Gatherer shall keep and maintain proper books
of account during the term of this Agreement and for a period of three (3) years
thereafter showing (a) the total volume of Shipper's Gas transported through the
Gathering System from the Receipt Points to the Delivery Points and (b) the
volume of gas allocated to each Receipt Point. Gatherer shall also preserve, or
cause to be preserved, for at least one (1) year all test data, charts, and
similar data pertaining to the measurement and testing of Shipper's Gas, unless
a longer period is prescribed by applicable regulations. Shipper shall have the
right during normal business hours, after reasonable notice to Gatherer, to
inspect Gatherer's books and records not older than three (3) years from the
date of request for inspection. Such inspections shall take place at Gatherer's
office. Any costs attributable to such audits or inspections shall be borne by
Shipper.

                                   Article 7.
                                 GATHERING FEES

         9.2. Uneconomic Operation. Notwithstanding anything contained herein to
the contrary, if at any time Gatherer determines, in its sole discretion, that
continued operation of all or any part of the Gathering System is not
economically justified, Gatherer may cease receiving Shipper's Gas from the
relevant part of the Gathering System and terminate this Agreement as to such
part of the Gathering System (the "Terminated System") by giving at least ninety
(90) days' notice to Shipper. In such event, and concurrently with such notice,
Gatherer shall offer Shipper the right to purchase the Terminated System from
Gatherer for $10.00. Shipper shall exercise such right on or before sixty (60)
days after receipt of the termination notice. Shipper shall be responsible for
all costs and expenses related to such purchase, including filing fees, and such
purchase shall be without recourse, representation or warranty. Closing on the
purchase shall be on the day specified in the termination notice as the
termination date. If the Terminated System is acquired by Shipper and remains
connected to any other portion of the Gathering System, Shipper shall have the
right to deliver natural gas from the Terminated System to the Gathering System,
and this Agreement shall continue in effect with respect to the natural gas so
delivered by Shipper.

         9.3. Removal of General Partner. In the event that the General Partner
is removed as general partner of Gatherer pursuant to Section 11.2 of the
Partnership Agreement under circumstances where cause (as such term is defined

         This Agreement and all operations hereunder shall be subject to all
valid laws, orders, directives, rules, and regulations of any governmental body,
agency, or official having jurisdiction in the premises, whether state or
federal. Notwithstanding any other provisions in this Agreement, in the event
the Federal Energy Regulatory Commission or other governmental authority imposes
a rule, regulation, order, law or statute which directly or indirectly
materially and adversely affects a party's ability to perform its obligations
under this Agreement, then the party so affected may terminate this Agreement as
to the wells or portions of the Gathering System affected thereby by giving ten
(10) days prior written notice to the other parties.

                                   Article 12.

         Shipper shall pay or cause to be paid all taxes and assessments imposed
on Shipper hereunder with respect to Shipper's Gas gathered hereunder prior to

assessments with respect to Gatherer's income, capital, properties, franchises
or similar matters relating solely to Gatherer's general business activities or

                                   Article 14.
                                  MISCELLANEOUS

         14.1. 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.

         14.2. Notice. All notices or requests or consents provided for or
permitted to be given pursuant to this Agreement must be in writing and must be
given by depositing same in the United States mail, addressed to the party to be
notified, postpaid, and registered or certified with return receipt requested or
by delivering such notice in person or by telecopier to such party. Notice given
by personal delivery or mail shall be effective upon actual receipt. Notice
given by telecopier shall be effective upon actual receipt if received during
the recipient's normal business hours, or at the beginning of the recipient's
next business day after receipt if not received during the recipient's normal
business hours. All notices to be sent to a party pursuant to this Agreement
shall be sent to 311 Rouser Road, P.O. Box 611, Moon Township, Pennsylvania
15108, Facsimile: (412) 262-2820, Attention: Tony C. Banks at such other address
as such party may stipulate to the other parties in the manner provided in this
Section.

         14.3. Entire Agreement. This Agreement constitutes the entire agreement
of the parties relating to the matters contained herein, superseding the
provisions of all other contracts or agreements, whether oral or written, that
are in conflict with the provisions hereof.

         14.4. 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 Person of the same or any other obligations of such Person
hereunder. Failure on the part of a party to complain of any act of any Person
or to declare any Person 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.

         14.5. 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 Gatherer may not, without the prior approval of
the conflicts committee of the General Partner, agree to any amendment or
modification of this Agreement that, in the reasonable discretion of the General
Partner, will adversely affect the Common Unit holders.

         14.6. Assignment. No party shall have the right to assign its rights or
obligations under this Agreement without the consent of the other parties
hereto.

         14.7. 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.

         14.8. Severability. If any provision of this Agreement or the
application thereof to any Person 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 Persons or
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.

         14.9. 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.

         14.10. 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
Gatherer, to enforce any provision of this Agreement or to compel any party to
this Agreement to comply with its terms.

         14.11. 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 deemed in any
way to qualify, modify or explain the effects of any such term or provision.

effective as of the date first written above.

                 ARTICLE 2. CONNECTIONS TO RESOURCE ENTITY WELLS

         2.1. Construction of Flow Lines from Connectable Wells. The Resource
Entities jointly and severally agree that, at their sole cost and expense, they
will construct up to 2,500 feet of Flow Line from any Connectable Well to the
Gathering System. Such Flow Lines shall be the property of the owner of the
relevant Resource Entity Well.

         2.3. Construction of Flow Lines from Other Resource Entity Wells.

                  2.3.1. Resource Entities' Right to Require Extension of the
Gathering System. With respect to Resource Entity Wells other than Connectable

give the MLP written notice of the intent to drill a Resource Entity Well
subject to this Section. Within 30 days of the date of the Resource Entities'
notice, the MLP shall advise the Resource Entities whether it wishes to exercise
its rights under this Section. If the MLP exercises its rights under this
Section, the Resource Entities shall complete construction of the Gathering
System extension within 60 days after the date designated by the Resource
Entities as the date the Resource Entity Well will be completed as a producing
natural gas well.

                  2.3.3. Connections with Other Delivery Points and Third Party
Gathering Systems. In the event the MLP does not exercise its rights under
Section 2.3.2, the Resource Entities may:

                           (i) connect the Resource Entity Well to an Other
Delivery Point, in which event the MLP shall be entitled to assume the costs of
constructing the connecting Flow Line. If the MLP elects to assume such costs,
it shall pay such costs to the Resource Entities within 30 days of receipt of
Resource Entities' invoice therefor and the Flow Line shall be the property of
the MLP and part of the Gathering System; or

                           (ii) connect the Resource Entity Well to a Third
Party Gathering System, in which event the MLP shall be entitled to assume the
costs of constructing the connecting Flow Line. If the MLP elects to assume such
costs, it shall pay such costs to the Resource Entities within 30 days of
receipt of the invoice therefor and the Flow Line shall be the property of the
MLP and part of the Gathering System. In addition, the Resource Entities shall
pay to the MLP fees as required under Section 7.4 of the Master Natural Gas
Gathering Agreement.

         2.4. Well Connections. All well connections to Resource Entity Wells
shall be at the direction of and in accordance with instructions and
requirements of the MLP consistent with other wells connected to the Gathering
System. Any such well shall be required to adhere to all of the operating,
safety, pressure, and measurement provisions contained in the Master Natural Gas
Gathering Agreement.

         2.5. Consulting Services in Connection with Acquisitions. The Resource
Entities agree to assist the MLP in seeking to identify for possible acquisition
Third Party Gathering Systems and to provide consulting services to MLP in
evaluating and acquiring any such identified gathering system. Further, the
Resource Entities agree to give the MLP written notice of the identification by
any of them of any Third Party Gathering System for possible acquisition by such
Resource Entity or any Affiliate (each, an "Identified Third Party Gathering
System"). Such notice shall identify the gathering system and its seller and the
proposed sales price of the Identified Third Party Gathering System, and shall
include all written information about the Identified Third Party Gathering
System provided to the Resource Entities by or on behalf of the seller as well
as any information or analyses compiled by the Resource Entities from other
sources. Within 30 days of the date of the Resource Entities' notice, the MLP
shall advise the Resource Entities in writing whether MLP wishes to acquire the
Identified Third Party Gathering System. If the MLP advises the Resource
Entities of its intent to acquire the Identified Third Party Gathering System,
the Resource Entities shall refrain from making an offer for the Identified
Third Party Gathering System except as permitted hereunder. If the MLP (i)
advises the Resource Entities that it does not intend to acquire the Identified
Third Party Gathering System, (ii) advises the Resource Entities of its intent
to acquire the Identified Third Party Gathering System but does not complete the
acquisition within 60 days of the MLP's notice of its intent to the Resource
Entities or (iii) fails to timely advise the Resource Entities of its intent,
any of the Resource Entities shall be free to acquire the Identified Third Party
Gathering System.

                   ARTICLE 3. CONSTRUCTION MANAGEMENT SERVICES

         3.1. Services to be Provided. In the event the MLP expands the
Gathering System or constructs a new addition to the Gathering System, whether
pursuant to Article 2 or otherwise, the Resource Entities agree to provide to
the MLP construction management services in connection with any such expansion
as requested by the MLP. In providing construction management services
hereunder, the Resource Entities shall provide the services of a general
contractor with respect to the applicable construction project.

         3.2. Construction Contract. For each such construction project, the MLP
and the relevant Resource Entity shall enter into a construction contract based
substantially on the most current versions of AIA Document A111 (Standard Form
of Agreement Between Owner and Contractor) and AIA Document A201 (General
Conditions of the Contract for Construction), provided that the basis of payment
shall be the cost of the work (including an allocable portion of the Resource
Entity's employee salaries and benefits) and the MLP shall not be required to
employ an architect. The Resource Entities shall not be entitled to any other
compensation for the performance of construction management services hereunder.

                    ARTICLE 4. STAND-BY FINANCING COMMITMENT

         4.1. Financing Commitment. For the period commencing on the date hereof
and ending on the fifth anniversary hereof, Atlas America and Resource Energy
agree to provide to the MLP funding of up to an aggregate of One Million Five
Hundred Thousand Dollars ($1,500,000) per annum to finance the cost of expanding
the Gathering System or constructing new additions to the Gathering System.
Atlas America and Resource Energy, jointly and severally, commit to provide such
funding, upon the MLP's written request therefor, by purchasing Common Units at
a price equal to the arithmetic average of the closing prices of the Common
Units on the American Stock Exchange, or, if the American Stock Exchange is not
the principal trading market for such security, on the principal trading market
for such security, for the twenty consecutive trading days ending on the trading
day prior to the purchase, or, if the fair market value of the Common Units
cannot be calculated for such period on any of the foregoing bases, the average
fair market value during such period as reasonably determined in good faith by
the members of the managing board of the General Partner.

         4.2. Procedures. The MLP shall give Atlas America and Resource Energy
written notice of its intent to exercise its rights under Section 4.1.
Thereafter, Common Units shall be issued to the appropriate Resource Entity,
against delivery of the purchase price therefor in immediately available funds,
within five business days of the date of each construction invoice issued by the
Resource Entity to the MLP pursuant to Article 3. Each Common Unit so issued
shall, upon receipt of payment therefor and issuance, be duly authorized,
validly issued and fully paid.

         4.3. Prohibited Uses. The MLP agrees to use the funds it obtains
pursuant to this Article 4 for the purposes of financing initial construction
costs only and further agrees that it will not request or use such funds for any
other purpose, including capital improvements or maintenance to existing
pipeline.

                         ARTICLE 5. THE GENERAL PARTNER

         5.1. New Investment Programs. Until the earlier of the expiration of
the Applicable Period or the closing of the Transfers described in the first
sentence of Section 5.2, the Resource Entities agree that they shall cause a
Manager of one of the Investment Programs currently existing to be designated as
the Manager for Investment Programs organized after the date hereof and that the
wells of Investment Programs organized after the date hereof shall be deemed to
be Future Investment Program Well Interests for the purposes of the Master
Natural Gas Gathering Agreement.

         5.2. Disposition of Interest in the General Partner. The Resource
Entities agree that they will not Transfer to any Person their ownership
interest in the General Partner unless they simultaneously (i) Transfer to the
same Person their ownership interest in the Manager of each of the Investment
Programs and (ii) cause their Affiliates having an ownership interest in the
General Partner or any Manager of an Investment Program to Transfer such
interest to the same Person. The provisions of this Section shall not apply to a
Transfer to a wholly- or majority-owned direct or indirect subsidiary or parent
of any of the Resource Entities so long as the Resource Entities' or their
parent continue to control the relevant general partner.

                             ARTICLE 6. TERMINATION

         This Agreement shall terminate, and no party shall have any further
obligation hereunder, in the event that the General Partner is removed as
general partner of the MLP pursuant to Section 11.2 of the Partnership Agreement
under circumstances where cause (as such term is defined in Section 1.1 of the
Partnership Agreement) for such removal does not exist and the General Partner
does not consent to that removal.

                            ARTICLE 7. MISCELLANEOUS

         7.1. Choice of Law; Submission to Jurisdiction. This Agreement shall be

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

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.
