                                  INTRODUCTION

      THIS DEVELOPMENT AGREEMENT (this "Development Agreement") from ENERGY
CORPORATION OF AMERICA, a West Virginia corporation, with offices at 4643 South
Ulster Street, Suite 100, Denver, Colorado 80237-2867 ("Assignor"), to
________________________, a trust corporation organized under the laws of the
State of _________, with offices ___________________________________________,
Attention: ________________, as trustee (the "Trustee"), acting not in its
individual capacity but solely as trustee of the Appalachian Gas Royalty Trust
(the "Trust") under that certain Amended and Restated Trust Agreement dated as
of ______________ (the "Trust Agreement") is delivered to be effective as of
7:00 a.m., Eastern Time, ___________, 2005 (the "Effective Time"). All
capitalized terms not otherwise defined herein shall have the meanings ascribed
to such terms in Article I below.

      Assignor and the Trustee contemporaneously herewith, have entered into
each of the following conveyances (i) Term Royalty Conveyance (West Virginia)
dated effective as of the Effective Time ("West Virginia Conveyance"), (ii) Term
Royalty Conveyance (Pennsylvania) dated effective as of the Effective Time
("Pennsylvania Conveyance") and (iii) Term Royalty Conveyance (Kentucky) dated
effective as of the Effective Time ("Kentucky Conveyance" and together with the
West Virginia Conveyance and the Pennsylvania Conveyance collectively the
"Conveyances").

      In connection with the Conveyances Assignor has agreed to undertake
certain obligations during the term of the Conveyances with respect to the
Subject Interests and the Development Wells.

                                    ARTICLE I
                                   DEFINITIONS

      This Article I defines certain capitalized words, terms, and phrases used
in this Development Agreement. Certain other capitalized words, terms, and
phrases used in this Development Agreement are defined elsewhere in this
Development Agreement.

      "Adjusted Development Well Value" With respect to each Development Well,
the value obtained by multiplying for each Development Well drilled or caused to
be drilled by Assignor during any Annual Period one (1) times the Working
Interest (stated as a decimal fraction or 1.00, where Assignor holds a 100%
Working Interest), that Assignor is required to bear in such Development Well.
For example, if Assignor holds an eighty-five percent (85%) Working Interest in
a Development Well, the computation would be:

                                  1 x .85 = .85

therefore, such Development Well would have a .85 Adjusted Development Well
Value.

                  DEVELOPMENT OF THE SUBJECT DEVELOPMENT LANDS

      SECTION 2.01 DRILLING PROGRAM.

            (a) OBLIGATION TO DRILL. In each of the first four Annual Periods
during the Term, Assignor shall, subject to the terms of this Article II, drill,
or cause to be drilled, at Assignor's sole cost, (i) such number of Development
Wells that is necessary to achieve the Annual Drilling Target and (ii) such
number of Development Wells as to achieve the Total Drilling Target prior to the
Drilling Obligation Completion Date; it being understood that the drilling and
testing operations may extend beyond the last day of an Annual Period for which
such Development Well is being included to meet Assignor's obligations under
this Section 2.01(a).

            (b) MEANING OF "DRILL." For purposes of this Section 2.01, to
"drill" means to commence the actual drilling of a Development Well, and
thereafter to drill that Development Well diligently to the target depth (or
target depths, in the case of multiple target producing horizons) that Assignor
has determined, in accordance with the Reasonably Prudent Operator Standard, may
encounter producing Gas horizons and then to test that Development Well for the
production of Gas.

            (c) ADDITIONAL DEVELOPMENT WELLS. Any number of Development Wells
drilled which result in the Annual Drilling Target being exceeded in any Annual
Period may be carried forward and applied against Assignor's obligation, if any,
under Section 2.01(a) for the subsequent Annual Period.

      SECTION 2.02 OBLIGATION TO COMPLETE AND EQUIP. Assignor shall, at
Assignor's sole cost attempt to complete each Development Well that reasonably
appears to Assignor, acting in accordance with the Reasonably Prudent Operator
Standard, to be capable of producing Gas in quantities sufficient to pay
completion, equipping, and operating costs. Assignor shall equip for production
each Development Well that is successfully completed and, when it is equipped
and connected to a gathering line or pipeline, shall commence production.
Assignor shall plug and abandon all Development Wells that are unsuccessful.

      SECTION 2.03 UNDRILLABLE LOCATIONS/FAILURE TO REACH TOTAL DEPTH. If
Assignor fails, in the exercise of the Reasonably Prudent Operator Standard, to
reach total depth in any

                                       4
<PAGE>

Development Well due to geological subsurface conditions or impenetrable
substances, such drill site or well shall be counted as a Development Well
hereunder. Nothing herein shall be construed to grant to the Trustee, for the
benefit of the Trust, any wells drilled on the Subject Development Lands after
the Total Drilling Target has been achieved.

      SECTION 2.04 TERMINATION. After the drilling obligations in Section
2.01(a) have been satisfied, Trustee on behalf of the Trust shall, on request,
execute, acknowledge, and deliver to Assignor a recordable instrument that
terminates this Development Agreement.

      SECTION 2.05 COSTS AND EXPENSES OF DEVELOPMENT WELLS. All costs associated
with or paid or incurred in connection with the initial drilling, testing,
completing, and equipping for production or plugging and abandoning of the
Development Wells shall be borne solely by Assignor, but Assignor may use any
Subject Gas in such operations without any duty to account to Trustee or the
Trust under any of the Royalty Interests or Conveyances.

      SECTION 2.06 SURVIVAL OF OBLIGATION. Assignor's obligation under Section
2.01(a) shall survive, even if (i) any of the Royalty Interest in the Subject
Development Lands is Transferred or released in whole or in part by Trustee on
behalf of the Trust or (ii) notwithstanding Sections 11.01 through 11.04 of each
of the Conveyances, Assignor Transfers, mortgages or pledges the Subject
Development Lands or Subject Interests.

      SECTION 2.07 ADDITIONAL LEASES. In the event that Assignor acquires any
additional leases ("Additional Lease") other than the Subject Interests in the
AMI Area prior to Assignor's satisfaction of Assignor's drilling requirements in
Section 2.01, Assignor and Trustee shall execute, acknowledge, and deliver an
instrument that amends this Development Agreement so that such Additional Lease
will be part of the Subject Interests and Subject Development Lands hereunder.

      SECTION 2.08 TITLE DUE DILIGENCE. Prior to commencing the drilling of any
Development Well, Assignor will perform such title due diligence and such title
curative work as would be performed by an oil and gas operator drilling a well
and acting in accordance with the Reasonably Prudent Operator Standard.

      SECTION 2.09 WELLS. Prior to the satisfaction of Assignor's drilling
requirements in Section 2.01, Assignor shall not, and shall cause its Affiliates
not to, nor permit any other Person to, drill any well in the AMI Area that will
not be a Development Well hereunder.

.. Assignor hereby covenants and agrees to enter into a deed of trust, fixture
filing, assignment of as-extracted collateral, security agreement and financing
statement ("Deed of Trust") in order that Assignor shall have granted a lien and
security interest creating a valid, perfected lien and security interest in and
to any of the Subject Development Lands located in the AMI Area designated the
"Yawkey Freeman AMI" on Exhibit B in order to support Assignor's development
obligations under Section 2.1 above. Notwithstanding the preceding, for purposes
of the Deed of Trust only, the value of such obligations under Section 2.1 shall
be capped at $24,000,000 and such amount shall be reduced as provided in such
Deed of Trust as Assignor completes its development obligations under Section
2.1.
