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.

         6.6. 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

                                       6
<PAGE>

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.

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

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 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

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.

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

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.
