     Section 1.04 Warranty.

          (a) The Warranty. Assignor warrants to Assignee, its successors and assigns, that the Subject
Interests are free of all Encumbrances created by, through, or under Assignor, but not otherwise,
except for the Permitted Encumbrances.

          (b) Remedies.

     (i) Subject to Section 1.04(b)(ii), in the event of a breach of the foregoing
warranty for any Subject Interest, Assignee’s sole remedy shall be to receive
payment on each applicable Quarterly Payment Date, out of Assignor’s Net Share of
Gas from other Development Wells in excess of that subject to the Royalty Interest
and the royalty interest created pursuant to the Perpetual PUD Conveyance (the
“Assignor Retained Gas”), subject to offset as provided below and without
interest (except such interest payable under this Conveyance on payments made after
the applicable due date as described in Section 5.02 below), of an amount equal to
the difference between (x) Assignee Gas (or the proceeds from the sale thereof) that
Assignee would have received with respect to such Development Well in the applicable
Computation Period if such warranty had not been breached and (y) Assignee Gas (or
the proceeds from the sale thereof) that Assignee actually received during that
Computation Period with respect to that Development Well, to the extent such
difference is attributable to the breach of the warranty, but not to the extent that
such difference is attributable to any other cause, and any such amounts of Assignor
Retained Gas shall be treated as Assignee Gas.

     (ii) In the event a breach of the foregoing warranty for any Subject Interest
is due to production burdens in excess of twelve and one half percent (12.5%) with
respect to a Development Well, Assignor shall pay to Assignee on each applicable
Quarterly Payment Date an amount equal to that which Assignee would have received
with respect to such Development Well in the applicable Computation Period if such
warranty had not been breached out of Assignor Retained Gas, and such excess
production burdens will be fully allocated against Assignor’s retained interest in
such Development Well.

          (c) Right of Offset. If any Subject Interest owned by Assignor ever proves to be larger as of
the Effective Date than the Subject Interest reflected in the exhibits to this Conveyance and if,
as a result, Assignee receives a greater amount of Assignee Gas (or the proceeds from the sale
thereof) with respect to that Subject Interest than Assignee would otherwise have received if the
Subject Interest had been the size warranted, then such increased amounts, whenever received by
Assignee, may be treated by Assignor as a credit or offset (without interest) against any amounts
payable to Assignee under Section 1.04(b).

          (d) DISCLAIMER. EXCEPT FOR THE WARRANTIES OF TITLE GIVEN IN SECTION 1.04(a), ASSIGNOR MAKES
THIS CONVEYANCE AND ASSIGNS

of Assignee in and to all covenants of warranty by Third Persons (other than Affiliates of
Assignor) heretofore given or made with respect to the Development Wells, the Subject Interests or

     Section 3.03 Assignee Proceeds. “Assignee Proceeds” means the volume of Assignee Gas (on an Mcf basis or MMBtu basis, as
applicable) for the applicable Computation Period multiplied by the relevant Sales Price less the
Chargeable Costs associated with such Assignee Gas for the applicable Computation Period.

ARTICLE IV

MARKETING OF ASSIGNEE GAS

     Section 4.01 Rights and Duties Regarding Sale of Assignee Gas. Assignor shall market or shall cause to be marketed Assignor’s Net Share of Gas (including
Assignee Gas) in good faith and in accordance with the Reasonably Prudent Operator Standard and
Section 4.02(d). Assignor shall use its reasonable efforts in connection with any sale of
Assignor’s Net Share of Gas (including Assignee Gas) to obtain, as soon as reasonably practicable,
full payment for such Gas; provided, however, that it shall not be considered a breach of
Assignor’s marketing duty or standard of conduct for Assignor to market such Gas to an Affiliate of
Assignor, so long as Assignor does not market such Gas at a volume-weighted average price lower
than the volume-weighted average price upon which Assignor pays royalties to the owners of the
other royalty interests in the Subject Gas, save and excepting Chargeable Costs provided for in
Article III hereof.

     Section 4.02 Assignee’s Agent and Representative.

          (a) Appointment. Assignee appoints Assignor as Assignee’s agent and representative to market
and deliver or cause to be marketed and delivered all Assignee Gas and to collect and receive all
payments therefrom under any gas purchase agreement or contract without deduction (except to the
extent Chargeable Costs are deducted for any Computation Period). The appointment of Assignor as
Assignee’s agent and representative for such purpose is a material item of consideration to the
Parties in connection with the execution and delivery of this Conveyance. Assignee may not remove
Assignor from office as Assignee’s agent and representative, except for cause upon a material
breach by Assignor of its duties to Assignee under this Conveyance.

          (b) Duties and Powers. As Assignee’s agent and representative, Assignor shall receive all
payments for the sale of Assignee Gas and account to Assignee, receive and make all communications
with the purchaser of such Gas, and otherwise act and speak for Assignee in connection with the
sale of Assignee Gas. Third Persons may rely conclusively on the authority of Assignor to market
Assignee Gas, and with respect to Third Persons, Assignee shall be conclusively bound by the acts
of Assignor in connection with the sale of Assignee Gas. It shall not be necessary for Assignee to
join Assignor in the execution of any division order, transfer order, or other instrument,
agreement, or document relating to the sale of Assignee Gas. Third Persons may pay all Assignee
Proceeds for the sale of such Gas directly to Assignor, without the necessity of any joinder by or
consent of Assignee or any inquiry into the use or disposition of such proceeds by Assignor.

          (c) Prohibited Acts. Assignor may not act for or bind Assignee on any matter, except the
marketing and delivery of Assignee Gas under this Article IV.

13

 

          (d) Standard of Conduct. In exercising its powers and performing its duties as Assignee’s
agent and representative, Assignor shall act in good faith and in accordance with the Reasonably
Prudent Operator Standard. It shall not be a violation of such standard of conduct for Assignor
(i) to sell Assignor’s Net Share of Gas or Assignee Gas to an Affiliate pursuant to any gas
purchase agreement or contract, or (ii) to delegate some or all of Assignor’s duties as Assignee’s
agent and representative to its Affiliates (so long as such Affiliates perform in good faith and in
accordance with the Reasonably Prudent Operator Standard), with Assignor remaining liable to
Assignee for the performance of such Affiliates.

          (e) Termination of Authority. Assignor may not resign as Assignee’s agent and representative
without the prior written consent of Assignee, except that Assignor may resign as Assignee’s agent
and representative without such consent with respect to any Subject Interests assigned, sold,
transferred, or conveyed by Assignor in accordance with the terms of this Conveyance. If such sale
is made subject to the Royalty Interest, Assignor must cause the purchaser to assume the duties of
Assignee’s agent and representative with respect to the Subject Interests acquired by that
purchaser and to be bound by the provisions of this Article IV.

     Section 4.03 Delivery of Subject Gas. Assignor (whether or not it is serving as Assignee’s agent and representative) shall deliver or
cause to be delivered Assignor’s Net Share of Gas (including Assignee Gas) to the purchasers
thereof into the pipelines to which the Development Wells producing such Gas are connected.

     Section 4.04 Processing. Assignor may process Assignor’s Net Share of Gas (including Assignee Gas) to remove liquid and
liquefiable hydrocarbons and may commit any of the Subject Interests (including the Royalty
Interest attributable thereto) to an agreement for processing minerals (pursuant to which, for
example, the plant owner or operator receives a portion of the Subject Gas or plant products
therefrom or proceeds of the sale thereof as a fee for processing), so long as Assignor enters into
such processing arrangements in good faith and in accordance with the Reasonably Prudent Operator
Standard. Assignee shall be bound by such arrangements, shall permit Assignor’s Net
Share of Gas (including Assignee Gas) to be processed by Assignor or its contractor, and shall have
no right to any liquid or liquefiable hydrocarbons obtained by such processor or to the proceeds
from the sale thereof. Assignee shall not, however, be personally liable for any costs or risks
associated with such processing operations, but Assignee shall indirectly suffer the Btu reduction
and volume reductions associated with processing through corresponding reductions in the Btu
content and volumes of Assignee Gas.

ARTICLE V

PAYMENT

     Section 5.01 Obligation to Pay.

          (a) Quarterly Payment Amount. On each Quarterly Payment Date, Assignor shall prepare, in good
faith, an estimate of the cash to be paid to Assignee from (A) all of the proceeds (including any
interest earned thereon and payable to Assignee pursuant to Section 5.01(b) or Section 5.01(e)) to
be paid to Assignee from the sale of Assignee Gas produced during such Computation Period; plus (B)
all of the proceeds (including any interest

14

 

earned thereon and payable to Assignee pursuant to
Section 5.01(b) or Section 5.01(e)) to be paid to Assignee from the sale of Assignee Gas, if any,
produced during any prior Computation Periods, to the extent not previously taken into account for
purposes of determining a Quarterly Payment Amount for any prior Computation Periods, as such sum
may be (x) increased or decreased as a result of any adjustments to the estimates that were
previously made pursuant to this Section 5.01(a) for any prior Computation Periods that are
necessary to accurately report the proceeds from the sale of Assignee Gas for such prior
Computation Periods, (y) increased by the amount of any damages payable to Assignee under Section
1.04(b) (subject to the right of set-off in Section 1.04(c)) during the most recently completed
Computation Period prior to such Quarterly Payment Date and (z) decreased by any Reserved Amounts
as provided in Section 5.04 below (“Quarterly Payment Amount”).

          (b) The Obligation. After each Computation Period and on or before the Quarterly Payment Date
for that Computation Period, Assignor shall tender to Assignee the Quarterly Payment Amount with
respect to the applicable Computation Period. With respect to the final Computation Period,
Assignor shall tender to Assignee all unexpended Reserved Amounts (together with any interest
accrued thereon).

          (c) Quarterly Payment Date. “Quarterly Payment Date” for each Computation Period
means the thirtieth (30th) day after the end of such Computation Period or, for the last
Computation Period, the thirtieth (30th) day after the Termination Date. If such day is
not a Business Day, the Quarterly Payment Date shall be the next Business Day.

          (d) No Segregated Account. All amounts received by Assignor from the sale of Assignor’s Net
Share of Gas and Assignee Gas, as applicable, for any Computation Period shall be held by Assignor
in one of its general bank accounts and Assignor will not be required to maintain a segregated
account for such funds.

          (e) Disputed Proceeds. If Assignor receives any amounts of money from the sale of Assignee
Gas that is subject to controversy or, in the reasonable opinion of Assignor, possible controversy,
Assignor shall promptly deposit the money with a Third Person escrow agent in a segregated
interest-bearing account. Such amount shall not be treated as a portion of Assignee Proceeds so
long as it remains with such escrow agent, but shall be treated as a portion of Assignee Proceeds,
along with the accrued interest, when received from such escrow agent and paid over to Assignee.

     Section 5.02 Interest on Past Due Payments.

          (a) Obligation to Pay. Any Assignee Proceeds or other amounts of money not paid by Assignor
to Assignee when due shall bear, and Assignor will pay, interest at the Prime Interest Rate on the
overdue amount commencing on the sixth (6th) day after such due date until such amount
is paid.

          (b) Definition. “Prime Interest Rate” means the lesser of (i) the rate of interest
per annum publicly announced from time to time by The Bank of New York Mellon Trust Company, N.A.
as its “prime rate” in effect at its principal office in New York City (each change in the Prime
Rate to be effective on the date such change is publicly announced), with the

15

 

understanding that
such bank’s “prime rate” may be one of several base rates, may serve as a basis upon which
effective rates are from time to time calculated for loans making reference thereto, and may not be
the lowest of such bank’s base rates or (ii) the maximum rate of interest permitted under
applicable Legal Requirement.

     Section 5.03 Overpayments and Refunds.

          (a) Overpayments. If Assignor ever pays Assignee more than the amount of money then due and
payable to Assignee under this Conveyance, Assignee shall not be obligated to return the
overpayment, but Assignor may at any time thereafter deduct from Assignee Proceeds and retain for
its own account an amount equal to the overpayment.

          (b) Refunds. If Assignor is ever legally obligated to pay any Third Person, including any gas
purchaser or Governmental Authority, any refund, interest, penalty, or other amount of money,
because any payment of Assignee Proceeds received by Assignor for the account of Assignee exceeded,
or allegedly exceeded, the amount due or lawful under any applicable contract, Legal Requirement,
or other obligation, Assignor may thereafter deduct from Assignee Proceeds and retain for its own
account an amount equal to such payment.

     Section 5.04 Reserved Amounts. At any time and from time to time under this Conveyance and in accordance with the Reasonably
Prudent Operator Standard, Assignor may set aside from Assignee Proceeds amounts determined in good
faith to economically accrue for a Computation Period with respect to known or anticipated costs or
liabilities (the “Reserved Amounts”) which may be incurred in future
Computation Periods with respect to Taxes assessed or levied with respect to a time period in
excess of a calendar quarter. As Reserved Amounts are expended by Assignor to cover applicable
Taxes in a Computation Period, Chargeable Costs shall be reduced in such Computation Period by an
amount equal to the Reserved Amounts so expended. In the event that Assignor overestimates the
cost of any Taxes for which it has set aside Reserved Amounts, the excess amount shall be applied
against any other Chargeable Costs (which shall be reduced by an amount equal to such excess
Reserved Amounts so expended), or paid as Assignee Proceeds on the Quarterly Payment Date following
the Computation Period in which it is determined that Assignor has set aside excess Reserved
Amounts.

ARTICLE VI

RECORDS AND REPORTS

     Section 6.01 Books, Records, and Accounts.

          (a) Obligation to Maintain. Assignor shall maintain true and correct books, records, and
accounts of (i) all transactions required or permitted by this Conveyance and (ii) the financial
information necessary to effect such transactions, including the financial information needed to
calculate each installment of Assignee Proceeds.

          (b) Right of Inspection. Assignee or its representative, at Assignee’s expense, may inspect
and copy such books, records, and accounts in the offices of Assignor during normal business hours
and upon reasonable notice.

     Section 6.02 Statements.

16

 

          (a) Quarterly Statements. On each Quarterly Payment Date, Assignor shall deliver to Assignee
a statement showing the computation of Assignee Gas and Assignee Proceeds for the preceding
Computation Period.

          (b) Annual Statements. On the first Quarterly Payment Date after the end of each calendar
year and on the Quarterly Payment Date after the Termination Date, such statement shall also show
the computation of Assignee Proceeds for the preceding calendar year or, for the Quarterly Payment
Date after the Termination Date, for the portion of the calendar year from 7:00 a.m. Eastern Time
on January 1 of that same year through the Termination Date.

          (c) Contents of Statements. Without limiting the generality of the foregoing provisions in
this Section 6.02, each statement delivered by Assignor to Assignee pursuant to this Section 6.02
shall state, for the relevant period, (i) the total volumes of Subject Gas produced from the
Subject Lands, (ii) the total volumes of the Assignor’s Net Share of Gas, (iii) the total volumes
of Assignee Gas, (iv) the applicable Sales Price, (v) the amount of Assignee Proceeds due and
payable for the relevant period and (vi) the amounts of money, if any, due and payable by any
purchaser of the Subject Gas or Assignee Gas, the nonpayment of which resulted in the payment to
Assignee of less than Assignee Proceeds for the relevant period. Notwithstanding
the preceding, Assignor shall only be required to provide the preceding information on an
aggregate basis.

     Section 6.03 Assignee’s Exceptions to Quarterly Statements. If Assignee takes exception to any item or items included in any quarterly statement required by
Section 6.02, Assignee must notify Assignor in writing within sixty (60) days after Assignee’s
receipt of such quarterly statement. Such Notice must set forth in reasonable detail the specific
charges complained of and to which exception is taken or the specific credits which should have
been made and allowed. Adjustments shall be made for all complaints and exceptions that are
justified. Notwithstanding anything to the contrary herein, all matters reflected in Assignor’s
statements for the preceding calendar year (or portion thereof) that are not objected to by
Assignee in the manner provided by this Section 6.03 shall be deemed correct as rendered by
Assignor to Assignee.

     Section 6.04 Other Information.

          (a) Disclosure. At Assignee’s request, subject to applicable restrictions on disclosure and
transfer of information, Assignor shall give Assignee and its designated representatives reasonable
access in Assignor’s office during normal business hours to all geological, Development Well, and
production data in Assignor’s possession or Assignor’s Affiliates’ possession, relating to
operations on the Subject Interests.

          (b) Disclaimer of Warranties and Liability. Assignor makes no representations or warranties
about the accuracy or completeness of any such data, reports, or studies and shall have no
liability to Assignee or any other Person resulting from such data, studies, or reports.

17

 

          (c) No Attribution. Assignee shall not attribute to Assignor or to the consulting engineers
any reports or studies or the contents thereof in any securities filings or reports to Assignee.

          (d) Confidentiality. All information furnished to Assignee and its designated representatives
pursuant to this Section 6.04 is confidential and for the sole benefit of Assignee and shall not be
disclosed by Assignee or its designated representatives to any other Person, except to the extent
that such information (i) is required in any report, statement or testimony submitted to any
Governmental Authority having or claiming to have jurisdiction over Assignee or submitted to bank
examiners or similar organizations or their successors, (ii) is required in response to any summons
or subpoena or in connection with any litigation, (iii) is believed to be required in order to
comply with any applicable Legal Requirement to Assignee, (iv) was publicly available or otherwise
known to the recipient at the time of disclosure or (v) subsequently becomes publicly available
other than through any act or omission of the recipient; provided, however, with respect to the
disclosures with respect to items (i), (ii) and (iii) above, Assignee will notify Assignor prior to
any such disclosure in order to provide Assignor an opportunity to seek to limit any such required
disclosure.

ARTICLE VII

NO LIABILITY OF ASSIGNEE

     Assignee shall not be personally liable or responsible under this Conveyance for any cost,
risk, liability, or obligation associated in any way with the ownership or operation of the Subject
Lands, the Subject Interests, the Development Wells, or the Subject Gas. The foregoing sentence
does not restrict the right of Assignor to deduct Chargeable Costs or Reserved Amounts in
calculating the volumes of Assignee Gas or Assignee Proceeds.

ARTICLE VIII

OPERATIONS

     Section 8.01 Standards of Conduct. Except as otherwise specifically provided in this Conveyance, Assignor shall (a) operate and
maintain the Subject Interests and (b) make elections under each applicable lease, operating
agreement, unit agreement, contract for development, and other similar instrument or agreement
(including elections concerning abandonment of any Development Well or release of any Subject
Interest) in good faith and in accordance with the Reasonably Prudent Operator Standard.

     Section 8.02 Abandonment of Properties. Nothing in this Conveyance shall obligate Assignor to continue to operate any Development Well
or to operate or maintain in force or attempt to maintain in force any Subject Interest when such
Development Well or Subject Interest ceases to produce, or Assignor determines, in accordance with
Section 8.01 above, that such Development Well or Subject Interest is not capable of producing Gas
in paying quantities. The expiration of a Subject Interest in accordance with the terms and
conditions applicable thereto shall not be considered to be a voluntary surrender or abandonment
thereof.

     Section 8.03 Insurance. Assignor may, but is not required by this Conveyance to, carry insurance on any Subject Interest
or Development Well, or covering any risk with respect

18

 

thereto. Assignor shall never be liable to
Assignee on account of any injury or loss to the Subject Interests or any Development Well, whether
insurable or uninsurable, not covered by insurance. If Assignor elects to carry insurance, the
premiums shall not be included in Chargeable Costs, and Assignor shall retain all proceeds of such
insurance.

ARTICLE IX

POOLING AND UNITIZATION

     Section 9.01 Pooling of Subject Interests. Certain Subject Interests have been, or may have been, heretofore pooled and unitized for the
production of Gas. Such Subject Interests are and shall be subject to the terms and provisions of
the applicable pooling and unitization agreements, and the Royalty Interest in each pooled or
unitized Subject Interest shall apply to and affect only the Gas produced from such units that
accrues to such Subject Interest under and by virtue of the applicable pooling and unitization
agreements.

     Section 9.02 Pooling and Unitization.

          (a) Right to Pool. Assignor has the exclusive executive right and power (as between Assignor
and Assignee) to pool or unitize any Subject Interest and to alter, change, amend, or terminate any
pooling or unitization agreements heretofore or hereafter entered into, as to all or any part of
the Subject Lands, as to any one or more of the formations or horizons, and as to any Gas, upon
such terms and provisions as Assignor shall in its sole discretion deem appropriate.

          (b) Effect of Pooling. If and whenever through the exercise of such right and power, or
pursuant to any Legal Requirement now existing or hereafter enacted or promulgated, any Subject
Interest is pooled or unitized in any manner, the Royalty Interest, insofar as it affects such
Subject Interest, shall also be pooled and unitized, and such Royalty Interest in such Subject
Interest shall apply to and affect only the Gas production that accrues to such Subject Interest
under and by virtue of the applicable pooling and unitization agreement or order. It shall not be
necessary for Assignee to agree to, consent to, ratify, confirm or adopt any exercise of pooling or
unitization of any Subject Interest by Assignor.

ARTICLE X

Assignee with any Governmental Authority having jurisdiction with respect to matters affecting the
Subject Interests, the Subject Lands, or the Subject Gas.

          (d) Separate Interest. Effective on the effective date of any Transfer of any Subject
Interest subject to this Section 11.01, Assignee Gas and Assignee Proceeds shall thereafter be
computed separately with respect to such Subject Interests, and the assignee, buyer, transferee, or
grantee of such Subject Interests shall thereafter serve as Assignee’s agent and representative
under Article IV with respect to such interests and shall pay all corresponding Assignee Proceeds
directly to Assignee.

     Section 11.02 Sale and Release of Properties.

          (a) Transfer. Subject to Section 11.05, Assignor may from time to time, Transfer the
Development Wells, the Subject Interests, or any part thereof or undivided interest therein, free
of the Royalty Interest and this Conveyance provided that the aggregate Fair Value of all Royalty
Interests released with respect to the Assignee Conveyances during any twelve (12) month period
shall not exceed $5,000,000.

          (b) Payments. In connection with any Transfer pursuant to this Section 11.02, Assignor shall
remit to Assignee an amount equal to the Fair Value of the Royalty Interest being released.
Assignor shall make such payment to Assignee on the Quarterly Payment Date for the Computation
Period in which Assignor receives the payment with respect to any such Transfer of the Subject
Interest.

          (c) Release. In connection with any Transfer provided for in Section 11.02(a), Assignee
shall, on request, execute, acknowledge, and deliver to Assignor a recordable instrument
(reasonably acceptable to Assignor) that releases the Royalty Interest with respect to the
Development Well and the related Subject Interests and Subject Lands being Transferred.

          (d) Effect of Sale. From and after the actual date of any such Transfer by Assignor, Assignor
and any assignee, purchaser, transferee or grantee of such Subject Interest shall be relieved of
all obligations, requirements, and responsibilities arising under the Royalty Interest or this

that accrued prior to such date.

20

 

     Section 11.03 Release of Other Properties.

          (a) Prior Reversionary Interests. In the event that any Person notifies Assignor that,
pursuant to a Prior Reversionary Interest, Assignor is required to convey any of the Subject
Interests to such Person or cease production from any Development Well, Assignor may provide such
conveyance with respect to such Subject Interest or permanently cease Production from any such
Development Well.

          (b) Payments. In the event that Assignor receives compensation pursuant to any Prior
Reversionary Interest in connection with any conveyance or permanent cessation of production from
any Development Well, Assignor shall remit to Assignee an amount equal to the product of (x) such
amount actually received by Assignor with respect to such reconveyance or permanent cessation of
production and (y) a fraction the numerator of which is (A) the Fair Value of the Royalty Interest
released and the denominator of which is (B) the Fair Value of the Subject Interest that is being
released. Assignor shall make such payment to Assignee on the Quarterly Payment Date for the
Computation Period in which Assignor receives such payment.

          (c) Release for Prior Reversionary Interests. In connection with any conveyance or permanent
cessation of production provided for in Section 11.03(a) above, Assignee shall, on request,
execute, acknowledge, and deliver to Assignor a recordable instrument (reasonably acceptable to
Assignor) that releases the Royalty Interest and this Conveyance with respect to any such
Development Well or Subject Interests.

          (d) Effect of Prior Reversionary Interests. From and after the actual date of any conveyance
or permanent cessation of production provided for in Section 11.03(a), Assignor and any assignee,
purchaser, transferee or grantee of such Subject Interest shall be relieved of all obligations,
requirements, and responsibilities arising under the Royalty Interest or this Conveyance with
respect to the Subject Interests Transferred, except for those that accrued prior to such date.

     Section 11.04 Farmouts.

          (a) Farmout. Assignor may from time to time enter into Farmout Agreements with Third Persons
with respect to the Subject Interests. In the event that Assignor enters into any Farmout
Agreement with a Third Person, the Royalty Interest and this Conveyance shall only burden
Assignor’s retained interest in the Subject Interest after giving effect to any interest in the
Subject Interest that a counterparty to the Farmout Agreement may earn under such Farmout
Agreement. Only the Assignor’s retained interest in the Subject Interest will count towards the
Assignor’s obligation to drill Development Wells under the Development Agreement.

          (b) Release. In connection with Assignor entering into any Farmout Agreement, Assignee shall,
upon request of Assignor, execute, acknowledge, and deliver to Assignor a recordable instrument
(reasonably acceptable to Assignor) that releases the Royalty
Interest and this Conveyance with respect to the Subject Interests being transferred pursuant
to such Farmout Agreement; provided, the Royalty Interest shall still burden the Subject Interest
retained by Assignor.

21

 

     Section 11.05 Transfer of Subject Lands. Assignor will not Transfer any Development Well or any of the Subject Interests comprising a
part of the Subject Lands pursuant to Sections 11.01 and 11.02 prior to the Drilling Obligation
Completion Date.

     Section 11.06 Change in Ownership.

          (a) Obligation to Give Notice. No change of ownership or of the right to receive payment of
the Royalty Interest, or of any part thereof, however accomplished, shall bind Assignor until
notice thereof is furnished to Assignor by the Person claiming the benefit thereof, and then only
with respect to payments made after such Notice is furnished.

          (b) Notice of Sale. Notice of sale, transfer, conveyance, or assignment shall consist of a
certified copy of the recorded instrument accomplishing the same.

          (c) Notice of Other Changes of Ownership. Notice of change of ownership or of the right to
receive payment accomplished in any other manner (e.g., by dissolution of Assignee) shall consist
of certified copies of recorded documents and complete proceedings legally binding and conclusive
of the rights of all Persons.

          (d) Effect of Lack of Notice. Until such Notice accompanied by such documentation is
furnished to Assignor in the manner provided above, Assignor may, at Assignor’s election, either
(i) continue to pay or tender all sums payable on the Royalty Interest in the same manner provided
in this Conveyance, precisely as if no such change in interest or ownership or right to receive
payment had occurred or (ii) suspend payment of Assignee Proceeds without interest until such
documentation is furnished.

          (e) Effect of Nonconforming Notices. The kinds of Notice provided by this Section 11.03(d)
shall be exclusive, and no other kind, whether actual or constructive, shall bind Assignor.

     Section 11.07 One Payee. Assignor shall never be obligated to pay Assignee Proceeds to more than one Person. If more
than one Person is ever entitled to receive payment of any part of Assignee Proceeds, Assignor may
suspend payments of all Assignee Proceeds until the concurrent owners or claimants of the Royalty
Interest or the right to receive payment of Assignee Proceeds appoint one Person in writing to
receive all payments of Assignee Proceeds on their behalf. Assignor may thereafter conclusively
rely upon the authority of that Person to receive payments of Assignee Proceeds and shall be under
no further duty to inquire into the authority or performance of such Person.

     Section 11.08 Rights of Mortgagee. If Assignee executes a mortgage or deed of trust covering all or part of the Royalty Interest,
the mortgagees or trustees therein named or the holders of any obligation secured thereby shall be
entitled, to the extent that such mortgage or deed of trust so provides, to exercise the rights,
remedies, powers, and privileges conferred upon Assignee by this Conveyance and to give or withhold
all consents required to be obtained from Assignee. This Section 11.08 shall not be deemed or
construed to impose upon Assignor any obligation or liability undertaken by Assignee under such
mortgage or deed of trust or under the obligation secured thereby.

ARTICLE XII

AMI AREA

     Section 12.01 Additional Leases. In the event that Assignor acquires any additional leases (“Additional Lease”) other
than the Subject Interests in the AMI Area prior the Drilling Obligation Completion Date, (i)
Assignor shall be subject to all of the limitations hereunder and under the Development Agreement
with respect to such Additional Leases(s), and (ii), subject to Section 12.03, at Assignor’s
option, Assignor and Trustee shall execute, acknowledge, and deliver an instrument that amends this
Conveyance so that such Additional Lease will be subject to the Royalty Interest and be part of the
Subject Interests and Subject Lands hereunder; provided that in no event shall Assignor extend any
well into such Additional Lease(s) unless and until this Conveyance is amended to include such
Additional Leases(s) as part of the Subject Interests.

     Section 12.02 Exchange of Subject Lands. Subject to Section 12.03, Assignor may, at its option at any time prior to the Drilling
Obligation Completion Date, cause Trustee to execute, acknowledge, and deliver to Assignor a
recordable instrument (reasonably acceptable to Assignor) that releases from the Royalty Interest
and this Conveyance portions of the Subject Interests in connection with Assignor’s exchange of
such Subject Interests for other properties within the AMI, which such other properties will made
subject to the Royalty Interests in this Conveyance (such other properties being hereafter referred
to as “Exchange Acreage”).

     Section 12.03 Limitations. In no event, however, may any Additional Lease be made subject to the Royalty Interest and this
Conveyance pursuant to Section 12.01, or any exchange be effected pursuant to Section 12.02 unless
Assignor certifies to the Trust that (a) no Development Well will be spud on the Additional Lease
or the Exchange Acreage, (b) the aggregate acreage attributable to all Additional Leases and all
Exchange Acreage will not exceed 5% of the Subject Lands as such exist as of the date of this
Conveyance, (c) if the Additional Lease and Exchange Acreage were treated as Subject Lands, the
portion of the Subject Lands that covers and pertains to Subject Gas in, under and that may be

with offices at 919 Congress Avenue, Suite 500, Austin, Texas 78701, as trustee (the
“Trustee”), acting not in its individual capacity but solely as trustee of the ECA

dated as of ___, 2010 (the “Trust Agreement”), is delivered to be effective as of
7:00 a.m., Eastern Time, April 1, 2010 (the “Effective Time”). All capitalized terms not
otherwise defined herein shall have the meanings ascribed to such terms in Article II below.

ARTICLE I

CONVEYANCE

     Section 1.01 The Grant. For and in consideration of good and valuable consideration paid by
Trustee on behalf of the Trust to Assignor, the receipt and sufficiency of which are hereby
acknowledged, Assignor has, subject to the terms of this Conveyance, BARGAINED, SOLD, GRANTED,
CONVEYED, TRANSFERRED, ASSIGNED, SET OVER, and DELIVERED, and by these presents does hereby
BARGAIN, SELL, GRANT, CONVEY, TRANSFER, ASSIGN, SET OVER, and DELIVER unto Trustee on behalf of the
Trust, as a perpetual net overriding royalty interest (the “Royalty Interest”), a variable
undivided interest in and to the Subject Interests, to the extent that the Subject Interests
pertain to Gas in, under and that may be produced and saved from the wellbores of the Wells,
sufficient to cause the Trust to receive the Trust Gas or proceeds thereof calculated and paid in
money in accordance with the further terms and conditions of this Conveyance.

     Section 1.02 Habendum Clause. TO HAVE AND TO HOLD the Royalty Interest, together with all and
singular the rights and appurtenances thereto in anywise belonging, unto Trustee on behalf of the
Trust, its successors and assigns, subject to terms and provisions of this Conveyance.

     Section 1.03 Warranty.

          (a) The Warranty. Assignor warrants to the Trust, its successors and assigns, that the
Subject Interests are free of all Encumbrances created by, through, or under Assignor, but not
otherwise, except for the Permitted Encumbrances, and that Assignor’s title to

1

 

the Wells entitles Assignor to a Net Revenue Interest with respect to the Target Formation in
each such Well no less than the Net Revenue Interest with respect to the Target Formation for that
Well set forth in Exhibit A.

          (b) Sole Remedy. In the event of a breach of the foregoing warranty for any Subject Interest,
the Trust’s sole remedy shall be to receive payment on each applicable Quarterly Payment Date, out
of Assignor’s Net Share of Gas from other Wells in excess of that subject to the Royalty Interest,
the royalty interest created pursuant to the Term PDP Conveyance and the royalty interest created
pursuant to the Investor Conveyance (“Assignor Retained Gas”), subject to offset as
provided below and without interest (except such interest payable under this Conveyance on payments
made after the applicable due date as described in Section 5.02 below), of an amount equal to the
difference between (i) Trust Gas (or the proceeds from the sale thereof) that the Trust would have
received with respect to such Well in the applicable Computation Period if such warranty had not
been breached and (ii) Trust Gas (or the proceeds from the sale thereof) that the Trust actually
received during that Computation Period with respect to that Well, to the extent such difference is
attributable to the breach of the warranty, but not to the extent that such difference is
attributable to any other cause, and any such amounts of Assignor Retained Gas shall be treated as
Trust Gas.

          (c) Right of Offset. If any Subject Interest owned by Assignor ever proves to be larger as of
the Effective Date than the Subject Interest reflected in the exhibits to this Conveyance and if,
as a result, the Trust receives a greater amount of Trust Gas (or the proceeds from the sale
thereof) with respect to that Subject Interest than the Trust would otherwise have received if the
Subject Interest had been the size warranted, then such increased amounts, whenever received by the
Trust, may be treated by Assignor as a credit or offset (without interest) against any amounts
payable to the Trust under Section 1.03(b).

          (d) DISCLAIMER. EXCEPT FOR THE WARRANTIES OF TITLE GIVEN IN SECTION 1.03(a), ASSIGNOR MAKES
THIS CONVEYANCE AND ASSIGNS THE ROYALTY INTEREST WITHOUT RECOURSE, COVENANT OR WARRANTY OF TITLE OF
ANY KIND, EXPRESS, IMPLIED OR STATUTORY. ANY COVENANTS OR WARRANTIES IMPLIED BY STATUTE OR LAW BY
THE USE HEREIN OF THE WORDS “GRANT”, “CONVEY” OR OTHER SIMILAR WORDS ARE HEREBY EXPRESSLY
DISCLAIMED, WAIVED AND NEGATED. WITHOUT LIMITING THE GENERALITY OF THE TWO PRECEDING SENTENCES,
TRUSTEE ON BEHALF OF THE TRUST ACKNOWLEDGES THAT ASSIGNOR HAS NOT MADE, AND ASSIGNOR HEREBY
EXPRESSLY DISCLAIMS AND NEGATES, AND THE TRUSTEE ON BEHALF OF THE TRUST HEREBY EXPRESSLY WAIVES,
ANY REPRESENTATION OR WARRANTY, EXPRESS, IMPLIED, AT COMMON LAW, BY STATUTE OR OTHERWISE RELATING
TO (i) PRODUCTION RATES, RECOMPLETION OPPORTUNITIES, DECLINE RATES OR THE QUALITY, QUANTITY OR
VOLUME OF THE RESERVES OF HYDROCARBONS, IF ANY, ATTRIBUTABLE TO THE SUBJECT INTERESTS, (ii) ANY
IMPLIED OR EXPRESS WARRANTY OF MERCHANTABILITY, (iii) ANY IMPLIED OR EXPRESS WARRANTY OF FITNESS
FOR A PARTICULAR PURPOSE, (iv) ANY IMPLIED OR EXPRESS WARRANTY OF CONFORMITY TO MODELS OR SAMPLES
OF MATERIALS, AND (v) ANY AND ALL IMPLIED WARRANTIES EXISTING UNDER ANY APPLICABLE LEGAL
REQUIREMENT; IT BEING THE EXPRESS INTENTION OF BOTH THE TRUST AND

2

 

ASSIGNOR THAT THE ROYALTY INTEREST IS HEREBY ASSIGNED TO THE TRUSTEE ON BEHALF OF THE TRUST ON
AN “AS IS” AND “WHERE IS” BASIS WITH ALL FAULTS, AND THAT THE TRUSTEE ON BEHALF OF THE TRUST HAS
MADE OR CAUSED TO BE MADE SUCH INSPECTIONS AS THE TRUST DEEMS APPROPRIATE. ASSIGNOR AND THE
TRUSTEE ON BEHALF OF THE TRUST AGREE THAT, TO THE EXTENT REQUIRED BY APPLICABLE LEGAL REQUIREMENTS
TO BE EFFECTIVE, THE DISCLAIMERS OF CERTAIN WARRANTIES CONTAINED IN THIS SECTION ARE “CONSPICUOUS”
DISCLAIMERS FOR THE PURPOSES OF ANY APPLICABLE LEGAL REQUIREMENT.

          (e) Substitution of Warranty. This instrument is made with full substitution and subrogation
of the Trust in and to all covenants of warranty by Third Persons (other than Affiliates of
Assignor) heretofore given or made with respect to the Wells, the Subject Interests or any part
thereof or interest therein.

necessary to accurately report the proceeds from the sale of Trust Gas for such prior Computation
Periods, (y) increased by the amount of any damages payable to the Trustee under Section 1.03(b)
above (subject to the right of set off in Section 1.03(c) above) during the most recently completed
Computation Period prior to such Quarterly Payment Date and (z) decreased by any Reserved Amounts
as provided in Section 5.04 below (“Quarterly Payment Amount”).

          (b) The Obligation. After each Computation Period and on or before the Quarterly Payment Date
for that Computation Period, Assignor shall tender to Trustee the Quarterly Payment Amount with
respect to the applicable Computation Period. With respect to the final Computation Period,

Share of Gas and the Trust Gas, as applicable, for any Computation Period shall be held by Assignor
in one of its general bank accounts and Assignor will not be required to maintain a segregated
account for such funds.

          (e) Disputed Proceeds. If Assignor receives any amounts of money from the sale of Trust Gas
that is subject to controversy or, in the reasonable opinion of Assignor, possible controversy,
Assignor shall promptly deposit the money with a Third Person escrow agent in a segregated
interest-bearing account. Such amount shall not be treated as a portion of Trust Proceeds so long
as it remains with such escrow agent, but shall be treated as a portion of the Trust Proceeds,
along with the accrued interest, when received from such escrow agent and paid over to Trustee.

such bank’s “prime rate” may be one of several base rates, may serve as a basis upon which
effective rates are from time to time calculated for loans making reference thereto, and may not be
the lowest of such bank’s base rates or (ii) the maximum rate of interest permitted under
applicable Legal Requirement.

     Section 5.03 Overpayments and Refunds.

          (a) Overpayments. If Assignor ever pays Trustee more than the amount of money then due and
payable to the Trust under this Conveyance, Trustee shall not be obligated to return the
overpayment, but Assignor may at any time thereafter deduct from Trust Proceeds and retain for its
own account an amount equal to the overpayment.

          (b) Refunds. If Assignor is ever legally obligated to pay any Third Person, including any gas
purchaser or Governmental Authority, any refund, interest, penalty, or other amount of money,
because any payment of Trust Proceeds received by Assignor for the account of Trustee exceeded, or
allegedly exceeded, the amount due or lawful under any applicable contract, Legal Requirement, or
other obligation, Assignor may thereafter deduct from Trust Proceeds and retain for its own account
an amount equal to such payment.

     Section 5.04 Reserved Amounts. At any time and from time to time under this Conveyance and in
accordance with the Reasonably Prudent Operator Standard, Assignor may set aside from Trust
Proceeds amounts determined in good faith to economically accrue for a Computation Period with
respect to known or anticipated costs or liabilities (the “Reserved Amounts”) which may be
incurred in future Computation Periods with respect to Taxes assessed or levied with respect to a
time period in excess of a calendar quarter. As Reserved Amounts are expended by Assignor to cover
applicable Taxes in a Computation Period, Chargeable Costs shall be reduced in such Computation
Period by an amount equal to the Reserved Amounts so expended. In the event that Assignor
overestimates the cost of any Taxes for which it has set aside Reserved Amounts, the excess amount
shall be applied against any other Chargeable Costs (which shall be reduced by an amount equal to
such excess Reserved Amounts so expended), or paid as Trust Proceeds on the Quarterly Payment Date
following the Computation Period in which it is determined that Assignor has set aside excess
Reserved Amounts.

produced from such units that accrues to such Subject Interest under and by virtue of the
applicable pooling and unitization agreements.

such terms and provisions as Assignor shall in its sole discretion deem appropriate.

          (b) Effect of Pooling. If and whenever through the exercise of such right and power, or
pursuant to any Legal Requirement now existing or hereafter enacted or promulgated, any Subject
Interest is pooled or unitized in any manner, the Royalty Interest, insofar as it affects such
Subject Interest, shall also be pooled and unitized, and such Royalty Interest in such Subject
Interest shall apply to and affect only the Gas production that accrues to such Subject Interest
under and by virtue of the applicable pooling and unitization agreement or order. It shall not be
