ARTICLE IV.

TENDER AND GATHERING OF GAS

     4.1. Tender of Production. Subject to the provisions of this Agreement, Shipper may
Tender to the Gathering System at the Point of Receipt all of its Production if, when and as
produced, each Day during the term of this Agreement.

     4.2. Firm Service. Subject to the terms of this Agreement, for each Day during the
term of this Agreement, Gatherer shall gather on the Gathering System for Shipper at the fees set
forth in Section 6.1 of Article VI, all of the Shipper’s Production produced and Tendered
during such Day, up to a volume not to exceed the Firm Capacity MDQ and redeliver an Equivalent
Thermal Quantity of Gas to or for the account of Shipper at the Point of Delivery (“Firm
Service”). Gatherer’s obligation to provide Firm Service under this Agreement is fundamental

     4.3. Authorized Overrun. Subject to the provisions of this Agreement, for each Day
during the term of this Agreement, Shipper may Tender to the Gathering System, at the fee(s) set
forth in Section 6.1 of Article VI, all of its Production in excess of the Firm Capacity
MDQ (the “Authorized Overrun”). Subject to the provisions of this Agreement and after
considering existing firm commitments and operations, Gatherer shall gather on the Gathering System
any or all of such Authorized Overrun, on the priority set out in Section 2.1 of Article
II of Exhibit C, attached hereto, to the extent Gatherer (in its sole discretion)
determines the Gathering System has available capacity (including at the Point of Receipt and Point
of Delivery).

ARTICLE V.

FIRM CAPACITY MDQ

     5.1. Production Profile. Shipper’s effective Firm Capacity MDQ during the term of this
Agreement shall be that set forth on Exhibit D.

     5.2. Firm Capacity MDQ Increases. Shipper’s Firm Capacity MDQ shall be increased upon
the request, made in good faith by Shipper only in the following circumstances:

	 	(A)	 	To reflect developmental drilling plans including but not limited
to subsequent re-drill, work-over, re-completion attempts or any other well
intervention which Shipper, in its sole opinion, deems appropriate.
	 
	 	(B)	 	To reflect initial production projections for new wells that may
be connected to the Point of Receipt.
	 
	 	(C)	 	Notwithstanding the above, Shipper’s Firm Capacity MDQ shall not
be increased unless Shipper supplies Gatherer with substantiating documentation
such as its drill plans, third party engineering studies and any other
information which Shipper reasonably believes supports its good faith request
for a Firm Capacity MDQ increase.

Provided, however, that any such increase(s) are subject to the availability of uncommitted
capacity in the Gathering System. In the event that capacity is not available, Gatherer shall have
sixty (60) Days from the date on which the request for Firm Capacity MDQ increase is received to
notify Shipper whether or not Gatherer will expand capacity for Firm Service to handle the
requested increase.

     5.3 Firm Capacity MDQ Decreases. In the event that, for any ninety (90) consecutive
Day period, the volumes of Shipper’s Production Tendered (plus any royalty-in-kind attributable to
Shipper’s production) do not equal at least 80% of Shipper’s Firm Capacity MDQ, the following shall
apply:

	 	(A)	 	Shipper’s Firm Capacity MDQ may be reduced, at Gatherer’s sole
option, prospectively to a level equal to ten percent (10%) over actual volumes
of Shipper’s average Monthly Production during the past Contract Year, subject
to Section 5.3(B) of this Article V.
	 
	 	(B)	 	Notwithstanding the foregoing subsection (A), if Shipper is able
to demonstrate to Gatherer that prospective period volumes of Shipper’s
Production is reasonably expected to occur at levels above actual volumes
reflected during the past Contract Year period under review,
such information will be considered in establishing any reductions to
Shipper’s Firm Capacity MDQ.

ARTICLE VI.

CHARGES 

     6.1 Gathering Fee. Shipper shall pay, on a monthly basis, an amount equal to:

	 	 	the product of the Gathering Fee set forth in Exhibit E times the sum of
the following quantity:

	 	 	All Production received and allocated to Shipper at the Point of Receipt.

     6.2 Demand Fee: Shipper shall pay, on a monthly basis an amount equal to:

	 	 	the amount of the Demand Fee as set forth on Exhibit E times the Firm Capacity MDQ as
reflected on Exhibit D,

provided, however, that no Demand Fee shall be due and payable to Gatherer for those Days
during which an event of Force Majeure has caused Gatherer to be unable to gather Shipper’s
Production.

     6.3 Fuel Usage Quantities. Each Month Shipper shall provide at the Point of Receipt
its pro rata share of any Fuel Usage Quantities, initially estimated to be 0%. In the event the
Fuel Usage Quantities become greater than zero (0), Gatherer shall notify Shipper regarding the
Fuel Usage Quantities charge (and an explanation of such charges setting forth in detail the
figures and calculations for such charges) that shall apply, on a throughput basis beginning with
the first day of the next calendar Month, to Shipper with regard to volumes Shipper actually
delivers for transmission through Gatherer’s Gathering System.

     6.4 Lost and Unaccounted-for Quantities. Each Month Shipper shall provide at the
Point of Receipt its pro rata share of actual line loss and unaccounted-for quantities actually
incurred by Gatherer.

ARTICLE VII.

RECEIPT AND DELIVERY PRESSURES

     7.1 Shipper shall deliver to Gatherer Gas Tendered pursuant to this Agreement at the Point of
Receipt at operating pressures that exist from time to time in the Gathering System, not to exceed
the MAOP of the Gathering System, as may be determined from time to time. If Shipper desires to
deliver Gas at the Point of Receipt on any Day in excess of such operating pressure, then Gatherer
shall have the right, but not the obligation, to receive such Gas at such higher operating
pressure. Gatherer’s refusal to receive Shipper’s Gas at such
higher operating pressure shall not relieve Shipper of any of its obligations under this
Agreement; provided, however, that if an event of Force Majeure renders the Gathering System unable
to receive Gas at the Point of Receipt at essentially the same operating pressure prevailing in the
Gathering System immediately prior to the event of Force Majeure, Shipper shall be relieved of its
obligations under this Agreement to the extent its firm capacity rights are curtailed consistent
with the terms of Exhibit C, Section 2.1, until such time as

Contract No.                     

Private and Confidential

Shippers capacity rights are fully
restored, when Shipper’s obligations will again be at one hundred percent (100%).

     7.2 Redeliveries of Gas by Gatherer to or for the account of Shipper at the Point of Delivery
shall be at such pressures that may exist from time to time in the Gathering System at the Point of
Delivery. Gatherer’s obligation to deliver Gas to the Point of Delivery shall be subject to the
operational limitations of any Downstream Transporter receiving such Gas, including capacity, Gas
measurement capability, and operating pressures. In no event shall Gatherer be required to
redeliver Gas at the Point of Delivery at a pressure in excess of the maximum required delivery
pressure at such Point of Delivery.

ARTICLE VIII.

TAXES AND ROYALTIES

     8.1 Shipper Taxes and Royalties. Shipper shall be responsible for all royalties and
applicable occupation, production, severance, sales or first use Btu and ad valorem taxes and all
taxes of similar nature or equivalent in effect on the Production gathered pursuant to this
Agreement, regardless of whether Shipper or Gatherer is given the responsibility of collecting and
paying such tax.

     8.2 Reimbursement of Taxes, Fees and Charges. Except as provided below, Shipper shall
reimburse Gatherer for Shipper’s proportionate share (relative to other shippers on the Gathering
System) of any future tax or any increase in an existing tax or other governmental exaction,
including any exaction under existing or future statute(s) validly levied on and paid by Gatherer
for, in respect of, or on account of the taking, gathering or delivery by Gatherer of the Gas
provided for in this Agreement, and except to the extent resulting from a violation of Law by
Gatherer, Shipper shall also be responsible for and reimburse Gatherer for Shipper’s proportionate
share (relative to other shippers on the Gathering System) of any tax, fee, or other charge levied
against Gatherer, pursuant to any applicable current or future Laws, for the purpose of creating a
fund for the prevention, containment, clean up and/or removal of spills. Such obligation to
reimburse shall specifically not include income, excess profits, capital stock or franchise taxes,
Gatherer ad valorem taxes (or other similar taxes related to the Gathering System) or any fines,
penalties or other fees, charges or amercements resulting from Gatherer’s failure to comply with
any current or future Laws, except to the extent such failure results from Shipper’s failure to
comply with current or future Laws.

     8.3. Right to Audit. For a period of twenty four (24) months following reimbursement
of any taxes, fees or other costs made by Shipper to Gatherer under the provisions of Sections
8.1 and/or 8.2, Shipper shall have the right to audit the books and records of Gatherer to the
extent related to assessment of the taxes, fees or other costs reimbursed by Shipper. During such
twenty four (24) month time period, Gatherer agrees to maintain its applicable books and records
and to make the same available to Shipper or Shipper’s designated representatives during Gatherer’s
normal business hours. Gatherer and

Gatherer Group from any and all Liabilities and/or Environmental Liabilities to the extent caused
by or resulting from the failure of Shipper’s Gas delivered hereunder to meet the quality
specifications set forth in Article III of Exhibit C, incurred by any member of the
Gatherer Group resulting from the Tender of any such non-conforming Gas by Shipper, REGARDLESS OF
THE NEGLIGENCE, STRICT LIABILITY OR OTHER FAULT (BUT EXCLUDING GROSS NEGLIGENCE OR WILLFUL
MISCONDUCT) OF ANY MEMBER OF GATHERER GROUP.

     10.6 Interruptions of Service. Notwithstanding anything to the contrary contained in
this Article, Shipper agrees to RELEASE, DEFEND, INDEMNIFY AND HOLD HARMLESS the Gatherer Group
from and against any Liabilities for claims by any party with whom Shipper is in privity of

(BUT EXCLUDING GROSS NEGLIGENCE OR WILLFUL MISCONDUCT) OF ANY MEMBER OF GATHERER GROUP.

     10.7 Limitation of Liability. NEITHER PARTY SHALL BE LIABLE TO THE OTHER FOR
CONSEQUENTIAL DAMAGES, INDIRECT DAMAGES, LOSS OF PROFITS, LOSS OF USE, OR PUNITIVE DAMAGES,
PROVIDED THAT THIS LIMITATION SHALL NOT APPLY TO ANY DAMAGE CLAIM ASSERTED BY OR AWARDED TO THIRD
PARTIES THAT ARE NOT AN AFFILIATE FOR WHICH A

PARTY TO THIS AGREEMENT WOULD OTHERWISE BE
RESPONSIBLE. No language in this Agreement is intended to provide indemnification greater than that
which is permitted by applicable law. If any limitations upon indemnification are imposed by
applicable law, then such limitations are hereby incorporated by reference and made a part of this
Agreement.

     10.8 Notice. In the event a claim is filed against either Party regarding matters
arising out of the activities contemplated under this Agreement, that Party shall promptly notify
the other Party of such claim. Participation by either Party in the defense of any such claim or
suit shall not constitute a waiver of that Party’s rights to indemnification hereunder.

     10.9 Insurance. Each Party shall procure and maintain insurance of such types, and
in such amounts, or at such Party’s option, self-insure, as is necessary to support the Party’s
indemnification obligations under this Agreement. To the extent permitted by law, each Party shall
ensure that its respective insurers waive all rights of subrogation against the other Party to the
extent of a Party’s indemnification obligations to the other Party under this Agreement.

     10.10 Anti-Indemnity. Each Party agrees that it will not, under any circumstances,
object to any indemnification obligation it may owe to another Party under this Agreement on the
grounds that such indemnification obligation is unenforceable under, or in conflict with, V.T.C.A.
Civil Practice and Remedies Code Section 127.001 et. seq. (commonly known as the Texas Oilfield
Anti-Indemnity Act).

MISCELLANEOUS

     13.1. Entire Agreement. This Agreement constitutes the entirety of the understanding
between the Parties with respect to the subject matter dealt with herein, and replaces and
supersedes all prior agreements, conditions, understandings, representations and warranties made
between the Parties with respect to the subject matter hereof, whether written or oral.

     13.2. Modifications. No modifications of the terms and provisions of this Agreement
shall be or become effective except by the execution by each of the authorized representatives of
Parties of a supplementary written agreement.

     13.3. Waiver. No waiver by either Party of any one or more defaults by the other
Party in performance of any provisions of this Agreement shall operate or be construed as a waiver
of any future default or defaults, whether of a like or a different character.

     13.4. No Third Party Beneficiaries. This Agreement is for the sole and exclusive
benefit of the Parties hereto. Except as expressly provided herein to the contrary, nothing herein
is intended to benefit any other Person not a Party hereto, and no such Person shall have any legal
or equitable right, remedy or claim under this Agreement.

     13.5. Successors and Assigns. This Agreement shall be binding upon and inure to the
benefit of the Parties and their respective permitted successors and assigns. Neither Party shall
assign or transfer its rights or obligations hereunder without the prior written consent of the
other Party; which consent shall not be unreasonably withheld; provided that consent shall not be
required for:

	 	(A)	 	an assignment or transfer of a Party’s rights or obligations
under this Agreement to an Affiliate(s) of such Party, which remains an
Affiliate(s), or

	 	(B)	 	a transfer, direct or indirect, of the equity ownership
(including, without limitation, a merger, consolidation, share exchange or
similar transaction) or a transfer of all or substantially all of the assets of
the direct or indirect parent of any Party, or

	 	(C)	 	a sale of one hundred percent (100%) of Shipper’s equity

assignor or transferor has provided the non-assigning or non-transferring Party with a copy of
such instrument. Any such assignment or transfer under this Agreement shall expressly provide in
writing that (a) such assignment or transfer is made subject to the terms of this Agreement as to
the interest transferred or assigned and (b) the assignee or transferee agrees to become a party
to, and be bound by this Agreement as to the interest transferred or assigned. Any attempted
assignment or transfer of any rights, title, interest, liabilities or obligations under this
Agreement in violation of the terms of this Agreement may be treated by the other Party as null and
void and of no force or effect.

     13.6 Confidentiality and Limited Disclosure. Each Party and its respective agents,
employees, officers, directors, attorneys, auditors and other representatives (including
individuals employed by lenders, accountants and other representatives of the disclosing party)
(collectively, “Representatives”) shall keep and maintain the terms and provisions of this
Agreement, but not the fact of its existence, in strict confidence, and shall not transmit, reveal,
disclose or otherwise communicate any of the provisions of this Agreement to any Person without
first obtaining the express written consent of the other Party, which consent shall not be
unreasonably withheld. In addition, neither Party, without the prior written consent of the
disclosing party, shall either (a) disclose the other Party’s Confidential Information, as defined
herein below, to anyone other than those Representatives who need to know it in connection with the
performance of this Agreement and have agreed to be bound by these obligations of confidentiality
or (b) use the other Party’s Confidential Information for any purpose other than in the performance
of this Agreement. For purposes of this Agreement, all data, maps, reports, drawings,
specifications, records, technical or engineering information, and computer programs/software
concerning a Party’s operations, processes or equipment that are provided and/or acquired in
connection with this Agreement shall be deemed Confidential Information. Notwithstanding the
foregoing, the receiving Party may disclose the Confidential Information without the disclosing
Party’s prior written consent (i) in connection with the sale or disposition, farm out or trade of
all or a portion of its interest in the Production; (ii) in connection with the sale or other
disposition (directly or indirectly) of all or substantially all of the assets of a Party, (iii) in
conjunction with a merger, consolidation, share exchange or other form of statutory reorganization
involving a Party; (iv) to a reputable financial institution(s) for study prior to the commitment
of funds; or (v) to the extent that such information:

	 	(A)	 	is already in the possession of the receiving Party at the time
of disclosure without binder of secrecy, or which is acquired independently
from a third party that, to the receiving Party’s knowledge, has the right to
disseminate said information at the time acquired by receiving Party; or

	 	(B)	 	is already in possession of the public or becomes available to
the public other than through the act or omission of the receiving Party; or

	 	(C)	 	is required to be disclosed under law or governmental authority
(provided that receiving party gives written notice to the disclosing Party
prior to such disclosure); or

	 	(D)	 	was independently developed by receiving party or its Representatives who
have not had access to the Confidential Information furnished hereunder; and

	 	(E)	 	any Confidential Data made available, other than with respect
to subparagraph (c) above shall not be removed from the custody or premises of
the Party making the Confidential Data available to third Parties. A third
party permitted access shall first agree in writing neither to disclose the
Confidential Data to others nor to use the Confidential Data except for the
purpose for which it was disclosed.

     In the event any such Confidential Information is sought from a Party by any court or
legislative or administrative body (whether by oral questions, interrogatories, subpoena, civil
investigations, demand or similar process), that Party agrees to:

	 	(i)	 	resist disclosure of said information on the grounds that it is
under an obligation not to disclose the information to third parties; and

	 	(ii)	 	promptly notify the other Party of the attempt to compel the
disclosure of the information in order to afford the disclosing Party an
opportunity to resist disclosure or to seek an appropriate protective order on
its own.

     13.7. Exhibits and Attachments. All exhibits, attachments and the like contained
herein or attached hereto are integrally related to this Agreement and are hereby made a part of
this Agreement for all purposes. To the extent of any ambiguity, inconsistency or conflict between
the body of this Agreement and any of the exhibits, attachments and the like attached hereto, the
terms of the body of this Agreement shall prevail.

     13.8. Choice of Law. THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED ACCORDING TO
THE LAWS OF THE STATE OF TEXAS WITHOUT REGARD TO ANY CHOICE OR CONFLICT OF LAWS RULES OR PRINCIPLES
WHICH, IF APPLIED, MIGHT PERMIT THE APPLICATION OF THE LAWS OF ANOTHER JURISDICTION.

     13.9. Further Assurances. Subject to the terms and conditions set forth in this
Agreement, each of the Parties agrees to use all reasonable efforts to take, or cause to be taken,
all actions, and to do, or to cause to be done, all things necessary, proper or advisable under
applicable Laws and regulations to consummate and make effective the transactions contemplated by
this Agreement. In case, at any time after the execution of this Agreement, any further action is
necessary or desirable to carry out its purpose, the proper officers or directors of the Parties
shall take or cause to be taken all such necessary actions.

     13.10. Survival. The representations, warranties, and indemnities given by the
Parties shall survive this Agreement without regard to any action taken pursuant to this Agreement
for a period of time coextensive with applicable statutes of limitations.

     13.11. Severability. Any term or provision of this Agreement that is invalid or
unenforceable in any jurisdiction shall be ineffective as to such jurisdiction, to the extent of
such invalidity or unenforceability, without rendering invalid or unenforceable the remaining terms
and provisions of this Agreement or affecting the validity or enforceability of any terms and
provisions of this Agreement in any other jurisdiction. If any provision of this Agreement is so
broad as to be unenforceable, each such provision shall be interpreted to be only so broad as is
enforceable. A bankruptcy or similar trustee must accept or, to the extent permitted by Law,
reject this Agreement in its entirety.

     13.12. Cumulative Rights, Obligations and Remedies. Except as expressly provided
herein, the rights, obligations and remedies created by this Agreement are cumulative and in
addition to any other rights, obligations or remedies otherwise available at law or in equity.
Other than the obligation to mediate pursuant to Section 13.22 of this Article XIII, in
lieu of seeking judicial remedies, nothing herein shall be considered an election of remedies. In
addition, any successful Party is entitled to costs related to enforcing this Agreement, including
without limitation, attorney’s fees and mediation expenses.

     13.13. Terminology. All personal pronouns used in this Agreement, whether used in the
masculine, feminine or neuter gender, shall include all other genders; the singular shall include
the plural, and vice versa. Articles, sections and other titles or headings are for convenience
only, and neither limit nor amplify the provisions of the Agreement itself, and all references
herein to articles, sections or subdivisions thereof shall refer to the corresponding article,
section or subdivision thereof of this Agreement unless specific reference is made to such
articles, sections or subdivisions of another document or instrument.

     13.14. Counterparts. This Agreement may be executed in multiple counterparts, each of
which, when executed, shall be deemed an original, and all of which shall constitute but one and
the same instrument.

     13.15. Time of the Essence. Time is of the essence with respect to any and all
obligations arising pursuant to this Agreement.

     13.16. Joint Effort. This Agreement shall be deemed to have been prepared equally
and jointly by the Parties.

     13.17.Economic Hardship. In the event that Gatherer’s cash outlays for operation
and maintenance expenses of the Gathering System, plus overhead and reasonable return on capital,
exceed the total of all Gathering System Fees received from Shipper and other shippers tendering
Gas on the Gathering System, or the lateral of such system on which said Gas is gathered, then
Gatherer shall have the right to request by written notice renegotiation of the Gathering Fee
payable hereunder. Such notice by Gatherer shall set forth in detail the figures and calculations
upon which Gatherer is relying on making its determination of such economic hardship. During
the sixty (60) day period from Gatherer’s written notification, Gatherer and Shipper shall in good
faith attempt to mutually agree upon a new Gathering Fee taking into account all fees received for
the operation of the Gathering System. The Gathering Fee for billing purposes shall not change
during the period of renegotiation. The new Gathering Fee agreed to through

renegotiation shall be effective sixty (60) days after the written notice requesting the
renegotiation of the Gathering Fee. In the event the Parties hereto have not reached an agreement
on a new Gathering Fee during said 60 day period, Gatherer shall provide service hereunder at a
Gathering Fee not less than that which results in revenues received hereunder equal to the
operation and maintenance expenses of Gatherer’s Gathering System (including overhead) and a
reasonable profit margin consistent with that of other gas gathering companies providing similar
services. Notwithstanding the foregoing or anything else in this Agreement to the contrary,
Gatherer shall not be required to continue service hereunder, and may cancel this Agreement with
thirty (30) days advance written notice, if a catastrophic event of Force Majeure renders the
rebuilding or repair of Gatherer’s Gathering System uneconomic, in Gatherer’s reasonable judgment.

Gatherer reserves the right to refuse to provide service or to terminate existing service at the
Point of Receipt and to terminate this Agreement upon thirty (30) days notice to Shipper, should
Gatherer, in its reasonable judgment, determine that the operation of the Gathering System is
uneconomic.

     13.18. [This section left blank intentionally.]

     13.19 Change in MMS Regulation. In the event at any time during the term of this
Agreement, including any extension(s) thereof, there is a change in Law that requires Gatherer to
reduce volumes of Production gathered on the Gathering System below the applicable Firm Capacity
MDQ in order to accommodate requests for gathering service by other shippers, then the stated Firm
Capacity MDQ for Shipper, as well as other shippers on the system with firm maximum daily
quantities shall be reduced prospectively from the effective date of such change in Law, such that
the Firm Capacity MDQ available for firm service during any Month, or such shorter time period as
may be mandated under such change in law, shall equal Shipper’s pro rata share of capacity
determined based upon the proportion that Shipper’s reasonable nomination bears to the total
nominations of all shippers for the period in question. For purposes of this Section 13.19,
the term “change in Law” shall mean a change in applicable rules or regulations promulgated by the
Minerals Management Service (“MMS”) or the Federal Energy Regulatory Commission (“FERC”) that
precludes gatherers operating in the Outer Continental Shelf from acting as contract carriers that
may offer shippers a quantity of reserved system capacity on a firm basis, and instead requires
such gatherers to make their system capacity available on a pro rata basis to all shippers
reasonably requesting access.

13.20 Laws:

	 	(A) It is understood by the Parties that this Agreement and performance
hereunder is subject to all present and future valid and applicable Laws.

	 	(B) The Parties are obligated to perform their respective duties under this
Agreement unless excused by Force Majeure or the unexcused failure of the other
Party’s performance. The Parties’ rights and obligations with respect to the
matters addressed herein are fixed by the terms of this Agreement. However, if at
any time during the Term

	 	 	 	of this Agreement a new Law or interpretation of an existing Law renders a
Party’s performance under this Agreement illegal, or effects a change in any
substantive provision of this Agreement that has a material adverse effect upon a
Party to this Agreement, then the affected Party shall notify the other in writing,
and Gatherer and Shipper shall negotiate in good faith to amend this Agreement in a
manner that will most nearly restore to the Parties the economic benefits and
burdens of this Agreement as existed prior to such change.

	 		 	(C) If Gatherer and Shipper are not able to agree within six months after a Party
first receives notice of the change from the affected Party on the terms of the
appropriate amendment to restore the Parties to their respective position, then the
Party adversely affected by the change may terminate this Agreement upon written
notice delivered to the other Party within 30 days after the expiration of such
six-month period.

	 	 	 	(D) Until such time as this Agreement is amended by mutual agreement, or terminated,
as applicable, each Party will meet all obligations under this Agreement, unless
otherwise prohibited by Law. In the event this Agreement is terminated as set forth
in Section 13.20(C) above, neither Party shall have any further liability to the
other Party except for any payments due or owing under this Agreement prior to such
termination and accrued liabilities existing at the time of such termination.

     13.21 Conflict of Interest. No director, employee, or agent of either Party, or
any contractor, subcontractor or vendor of either Party, shall give to or receive from any
director, employee or agent of the other Party, or any affiliate of the other Party, any
commission, fee, rebate, gift, or entertainment of significant cost or value in connection with
this Agreement.

     13.22 Dispute Resolution. Any Dispute shall be resolved in accordance with the
procedures specified in this Section 13.22, which shall be the sole and exclusive
procedures for the resolution of any Disputes.

	 	(A)	 	The Parties shall attempt in good faith to resolve any Dispute
arising out of or relating to the this Agreement promptly by negotiation
between senior management representatives who have authority to settle the
controversy and who are at a higher level of management than the persons with
direct responsibility for administration of this Agreement. Any Party may give
the other Party written notice of any Dispute not resolved in the normal course
of business. Within 21 Days after delivery of the notice, the receiving Party
shall submit to the other a written response. The notice and the response
shall include (a) a statement of each Party’s position and a summary of
arguments and evidence supporting that position, and (b) the name and title of
the senior management representative who will represent that Party and of
any other person who will accompany the senior management representative.
Within 30 Days after delivery of the disputing Party’s notice, the senior
management representatives of both Parties shall meet at a mutually
acceptable time and place, and thereafter as often as they reasonably deem
necessary, to attempt to resolve the Dispute. All

	 	 	 	reasonable requests for information made by one Party to the other will
be honored.

	 	(B)	 	If the Dispute has not been resolved by negotiation within 60
Days of the disputing Party’s notice, or if the Parties failed to meet within
the initial 30-Day period, the Parties shall endeavor to settle the Dispute by
mediation under the then current International Institute For Conflict
Prevention and Resolution (or if such association has ceased to exist, the
principal successor thereto) (“CPR”) commercial mediation procedures.
The mediation shall take place in Houston, Texas. Unless otherwise agreed,
the Parties will select a mediator from the CPR Panels of Distinguished
Neutrals, who will have experience in the natural gas industry.

	 	(C)	 	All negotiations pursuant to this clause are confidential and
shall be treated as compromise and settlement negotiations for purposes of
applicable rules of evidence.

	 	(D)	 	If the Dispute has not been resolved by mediation as provided
herein within 90 Days of the initiation of the above procedures, either Party
may initiate litigation upon 30 Days’ written notice to the other Party;
provided, however, that if one Party has requested the other to participate in
any of the above non-binding procedures and the other has failed to
participate, the requesting Party may initiate litigation before expiration of
the above period.

	 	(E)	 	Notwithstanding the provisions of this clause, either Party may
seek from any court having jurisdiction hereof any interim, provisional or
injunctive relief that may be necessary to protect the rights or property of
any Party or maintain the status quo before, during or after the pendency of
the mediation. The institution and maintenance of any judicial action or
proceeding for any such interim, provisional or injunctive relief shall not
constitute a waiver of the right or obligation of either Party to submit the
Dispute to negotiation or mediation as described above, including any claims or
disputes arising from the exercise of such interim, provisional or injunctive
relief.

meanings set forth in the Agreement.
	 
	II.	 	Nominations and Balancing

2.1 Allocation. Gatherer agrees to notify Shipper by telephone and confirm in
writing either electronically or via fax as soon as reasonably possible in the event that a
capacity curtailment allocation or interruption occurs. If, on any Day, insufficient
capacity exists on the Gathering System at either the Point of Receipt or Point of Delivery
such that Gatherer must limit services being provided by Gatherer on such Day, then, subject
to all applicable Laws, capacity on the Gathering System shall be allocated, if necessary
and for purposes of both scheduling of nominated quantities and curtailment of flowing
volumes, as follows, in descending order of priority:

(1) Firm Service MDQ capacity shall be allocated on a pro-rata basis among all
firm service agreements based on their respective MDQ entitlement and confirmed
nominations in effect at that time.

(2) Authorized Overrun services shall be allocated pro-rata based on confirmed
nominations in effect at that time.

(3) All interruptible services shall be allocated pro-rata based on each shipper’s
confirmed nominations for such services.

(4) All make-up quantities to correct imbalances shall have the lowest priority of
service on Gatherer’s Gathering System. Priority within this class shall be

If Shipper repeatedly fails to provide Gatherer any written nomination in the manner
required by this Section prior to delivery of Gas to Gatherer, or if Shipper repeatedly
nominates Gas for delivery hereunder and then fails to deliver such Gas to Gatherer other
than for reason(s) of Force Majeure, Gatherer may terminate this Agreement upon at least
fifteen (15) Days prior written notice. Shipper will have five (5) Days in which to cure
any defaults under this Section. The cure for any default hereunder shall be submitted to
Gatherer in writing within said 5-Day period, and Gatherer shall have three (3) Days to
either accept or reject such curative effort.

In the event that Shipper does not Tender sufficient Gas for gathering as nominated,
Gatherer shall have the right to reduce Shipper’s nomination to match Gas volume tendered
by Shipper and will notify Shipper of such cut in nominated volumes. Such notice may be
made by telephone, fax or other electronic means. Gatherer shall have the right to void
or adjust any nomination in the event Shipper does not Tender Gas for Gatherer as
nominated.

Gas delivered to Gatherer hereunder during any Day shall be delivered at as nearly
constant rate as operating conditions will permit.

3.3 Shipper and Gatherer, as applicable, shall monitor the quality of the Gas being tendered
to the Gathering System. If Gas Tendered by Shipper for gathering hereunder shall fail at
any time to conform to the specifications in Section 3.2 above or would cause the
Gas tendered by Gatherer to any Downstream Transporter to not meet the specifications of
such Downstream Transporter, then Gatherer shall immediately have the right to discontinue
gathering services hereunder and shall notify Shipper of such non-conforming Gas from
Shipper within a reasonable time after Gatherer has actual knowledge of such Tender of
non-conforming Gas from Shipper. From time to time, Gatherer (in its sole discretion) may
voluntarily waive such quality specifications and accept such non-conforming Gas but, such
waiver shall not prejudice Gatherer’s rights to later discontinue its acceptance of
non-conforming Gas.

3.4 Gatherer will use its reasonable efforts to ensure that no Gas received by Gatherer
from any source into the Gathering System will cause the commingled Gas to fail to meet the
quality specifications of the Gathering System.

	IV.	 	Measurement

4.1 Definitions. For purposes of this Article IV of this Exhibit C, the
following capitalized terms shall have the meanings ascribed below:

“British Thermal Unit” or “Btu” is the basic unit of thermal energy
measurement, which is referred to technically as the International Btu or Btu (IT), and is
commonly stated as one thousand fifty-five and five hundred fifty-nine ten-thousandths
Joules (1055.0559 J), (exact conversion 1055.055 852 62 J), as used for calculations
throughout the industry under GPA 2145 and GPA 2172. This amount of heat was historically
defined as that which will raise one (1) pound of water one degree Fahrenheit (1° F) near a
temperature of sixty degrees Fahrenheit (60°F) under atmospheric pressure.

“Standard Cubic Foot” or “scf”, is the basic unit of Gas volume
measurement and means the volume of Gas which will occupy one (1) cubic foot when corrected
for real Gas behavior to standard temperature of sixty degrees Fahrenheit (60oF),
and standard pressure of fourteen and seventy-three hundredths pounds per square inch

absolute (14.73 psia). This conversion shall be done according to generally accepted
engineering practice, using the latest revision of AGA Report No. 8.

“Mscf” means one thousand (1,000) scf.

“MMscf” means one million (1,000,000) scf.

4.2 Gatherer will own, operate and maintain the Point of Measurement equipment. Gatherer
shall at its expense perform or cause to be performed all measurement and testing of Gas.
Shipper may, at Shipper’s sole expense, install and operate Gas check-measuring equipment
that does not interfere with Gatherer’s measurement and testing.

4.3 Measurement and mathematical treatment of data shall be done according to accepted
industry practices, subject to standards set in the latest revisions of documents published
by the following entities: American Gas Association (AGA), Gas Processors Association
(GPA), American Petroleum Institute Manual of Petroleum Measurement Standards (API MPMS),
American National Standards Institute (ANSI), and Gas Research Institute (GRI). These
documents are often published by multiple organizations and are referenced here by one of
the most common designations. These are: AGA Report No. 3 / API MPMS Chapter 14.3 / GPA
8185 / ANSI/API 2530 “Orifice Metering of Natural Gases”, AGA Report No. 7 “Measurement of
Gas by Turbine Meters”, AGA Report No. 8 / API MPMS Chapter 14.2 / GRI publication
“Compressibility Factors of Natural Gas and Other Related Hydrocarbon Gases”, AGA Report No.
9 “Measurement of Gas by Multipath Ultrasonic Meters”, API MPMS Chapter 21 “Flow Measurement
Using Electronic Metering Systems”, GPA Standard 2145 “Table of Physical Constants for
Hydrocarbons and Other Compounds of Interest to the Natural Gas Industry”, GPA Standard 2166
“Obtaining Natural Gas Samples for Analysis by Gas Chromatography”, GPA Standard 2172 / API
MPMS Chapter 14.5 “Calculation of Gross Heating Value, Relative Density and Compressibility
Factor for Natural Gas Mixtures from Compositional Analysis”, GPA Standard 2261 “Analysis
for Natural Gas and Similar Gaseous Mixtures by Gas Chromatography”, GPA Standard 2286,
“Tentative Method of Extended Analysis for Natural Gas and Similar Gaseous Mixtures by
Temperature Programmed Gas Chromatography”.

4.4 Thermal energy associated with a quantity of Gas shall be that which is theoretically
transferred from the complete, ideal combustion of real, dry Gas in air beginning and ending
at standard temperature of sixty degrees Fahrenheit (60oF), and standard pressure
of fourteen and seventy-three hundredths pounds per square inch absolute (14.73 psia) with
all water formed by the reaction condensed to liquid. This is commonly referred to as a
gross, real, dry heating value when expressed in terms of the unit of thermal energy content
per unit of gas, e.g. Btu/scf.

4.5 Gas volumes shall be measured, calculated, and recorded by an Electronic Flow Meter
(“EFM”) operated according to API MPMS Chapter 21.

4.6 The EFM and end devices such as pressure transducers, temperature transducers, etc.
shall be calibrated as a system, or the proper functionality verified by appropriate means
on a monthly basis. This activity shall be open to representatives of the Parties upon
request. If a Party requests a special test of any measuring equipment, a prompt
verification shall be performed to ensure accuracy of the equipment. The expense of the
special test shall be borne by the requesting Party if the tested equipment is found to
produce an error of two percent (2%) or less in the Gas volume or energy content flow
recordings. During any test, the EFM reading of any transducer shall be brought into
agreement on a best-efforts basis to the calibration standard if the EFM reading is found to
differ by an amount greater than the uncertainty of the standard or the EFM uncertainty.

4.7 If upon calibration or verification, any error in measurement is discovered which caused
an error of two percent (2%) or less in the Gas volume or energy content, then the
previously measured quantities shall be considered accurate in computing Gas flow, but the
equipment shall be adjusted on a best-efforts basis to read accurately.

4.8 If upon calibration or verification, any error in measurement is discovered which caused
an error of more than one percent (1%) in the Gas volume or energy content, then the
previously measured quantities shall be corrected, and the equipment shall be adjusted on a
best-efforts basis to read accurately. Any previous error in measurement shall be corrected
to zero error for any period which is known definitely, but in the case where the period of
error is not known or cannot be agreed upon, such correction shall be applied to the latter
half of the period since the last test.

4.9 In the event a meter is out of service or registering inaccurately in excess of two
percent (2%), the quantities of Gas shall be determined as follows:

	 	(A)	 	By using the data recorded by any check measurement equipment
installed and believed to be accurately registering the data which were
recorded inaccurately by the custody transfer meter; or if this method is
unavailable,
	 
	 	(B)	 	By correcting the erroneous data if the magnitude of error is
ascertainable by calibration, test, or mathematical calculation; or if this
method is also unavailable,
	 
	 	(C)	 	By estimating the quantities of Gas by inference based on best
available data relating pipeline system performance to Gas quantities which
flowed under similar conditions to those during the time period in question.

4.10 Orifice meters shall be designed, installed, and operated according to the latest
revision of AGA Report No. 3 in effect at the time of such activity, and shall be

4.11. Gas turbine meters shall be designed, installed, and operated according to the latest
revision of AGA Report No. 7 in effect at the time of such activity, and shall be updated to
comply with revisions of AGA Report No. 7, as mutually agreed to by the Parties.

4.12 Ultrasonic meters shall be designed, installed, and operated according to the latest
revision of AGA Report No. 9 in effect at the time of such activity, and shall be updated to
comply with revisions of AGA Report No. 9, as mutually agreed to by the Parties.

4.13 Gas composition data shall be obtained from Gas chromatograph analysis of samples
obtained following procedures in GPA Standard 2166. Gas chromatography shall be performed
according to GPA Standard 2261 or GPA Standard 2286, as appropriate. Certain Gas property
data required for calculation of Gas volume flow and thermal energy flow shall be calculated
using methods described in GPA Standard 2172, while compressibility used for calculation of
Gas volumes shall be obtained according to AGA Report No. 8.

4.14 Gas composition data shall be derived from samples obtained from a proportional-to-flow
sampler, i.e. a sampling device set up to collect and aggregate a series of small samples in
proportion to Gas volume flow, from on-site real time chromatographic analysis, or from
other equipment or method as may be mutually agreed upon by the Parties. At a minimum,
composition data pertinent to determining Gas volume and thermal energy flow shall be
determined for the Point of Measurement(s) at least monthly.

4.15 Measurement data and calibration records shall be preserved in accordance with the
applicable rules and regulatory bodies having jurisdiction with respect to retention of such
records, and in any event, for at least twenty-four (24) Months after the end of the year to
which such records pertain. These records shall be made available to any Party having audit
rights to examine them under the terms and conditions governing such an audit.

4.16 If, at any time during the term hereof, a new method or technique is developed with
respect to Gas measurement or to the determination of the factors used in such Gas
measurement, such new method or technique may be substituted for the method set forth in
this Article IV when, in the opinion of the Parties, employing such new method or technique
is advisable.

Gatherer will use commercially reasonable efforts to provide Shipper its Firm Capacity MDQ as
described above in 2009 – 2012 of 130,000 MMBTU/D. Should Gatherer discover its pipeline capacity
cannot fulfill Firm Capacity MDQ as described above because of Gatherer’s physical limitations (not
because of commitments to any other shippers except for commitments of 1000 MMBTU/D to another
shipper), the MDQ through 11/30/2012 shall thereafter be reduced to actual (subject to other
shipper commitment) with other MDQ amounts unchanged and no refund obligation.
