Restated Credit Agreement

--------------------------------------------------------------------------------

(15) Effective as of July 26, 2011, Quest Transmission Company, LLC, a Delaware
limited liability company, was merged with and into PESC with PESC being the
surviving entity.

(16) Following the 2011 sale by Quest Eastern Resource LLC to an Affiliate of
Magnum Hunter Resources Corporation of certain producing properties in Wetzel,
Lewis and Braxton Counties, West Virginia, which properties were not collateral
for the Obligations but which secured the Amended QRC Facility (and which sale
excluded Quest Eastern Resources LLC’s gathering pipeline system to the extent
not located in Lewis and Wetzel Counties, the Heartwood Forestland #1 Hyman PH-2
well and the Haught P-2 salt well and remaining acreage in West Virginia and in
Steuben County, New York), the Amended QRC Facility was paid off and the Liens
securing the Amended QRC Facility were released.

(17) Quest Eastern Resource LLC changed its name to PostRock Eastern Production,
LLC on July 13, 2011.

(18) Pursuant to a Guaranty dated July 31, 2011, PostRock Eastern Production,
LLC became a Guarantor of the Obligations under this Agreement.

(19) Producing well bores located in West Virginia owned by MidContinent and
subject to an existing first Lien securing the Obligations and an existing
second Lien securing the Secured Pipeline Loan, were conveyed by MidContinent to
PostRock Eastern Production, LLC. Since already subjected to a Lien in favor of
the Collateral Agent for the benefit of the Lenders, PostRock Eastern
Production, LLC did not execute a mortgage on the acquired well bores.

(20) PESC pledged 100% of its equity in PostRock Eastern Production, LLC to
secure the Obligations.

(21) On February 21, 2012, the Secured Pipeline Loan was repaid in full by the
borrowers. Pursuant to Section 10.21 of this Agreement, the liens on KPC
Pipeline, LLC’s assets securing both the Secured Pipeline Loan and the
Obligations under this Agreement were released and terminated and the pledge of
KPC Pipeline, LLC’s equity was also terminated.

(22) In connection with the redetermination of the Borrowing Base to be

First Amendment to

Amended and

Restated Credit Agreement

--------------------------------------------------------------------------------

1.7 Section 2.04(c). Section 2.04(c) of the Credit Agreement is amended to read
as follows:

“(c) Mandatory Prepayments of Borrowing Base Value from Net Available Cash. An
amount equal to Borrowing Base Value of any Collateral sold in a Material
Disposition (other than a Disposition (whether a Material Disposition or
otherwise) of the Appalachia Assets which shall be governed by
Section 2.04(d)(i) and a Disposition (whether a Material Disposition or
otherwise) of the Constellation Equity which shall be governed by
Section 2.04(d)(iii)) shall be prepaid on the Revolving Loans (or be used to
Cash Collateralize Letters of Credit, if no Revolving Loans are outstanding) by
the selling Borrower or any of its Subsidiaries (other than the Excluded
Subsidiaries) to the extent payable out of the Net Available Cash received by
such Borrower or such Subsidiary. On any date on which a Borrower or another
Loan Party makes a Material Disposition of any of the Borrowing Base Oil and Gas
Properties, the Borrowing Base shall be automatically reduced by the Borrowing
Base Value of the properties so Disposed. Net Available Cash to the extent
received by the Borrower or such Subsidiary shall be used to prepay outstanding
Revolving Loans in an amount at least equal to the excess of Total Outstandings
over the reduced Borrowing Base (or to Cash Collateralize Letters of Credit, if
no Revolving Loans are outstanding). Following any such prepayment and reduction
of the Borrowing Base, any Borrower shall have the right to request a Borrowing
Base redetermination (which right shall be in addition to any Borrower’s right
to request a redetermination of the Borrowing Base pursuant to Section 2.02(h)).
(For clarification, a prepayment of the Revolving Loans may be reborrowed, if,
after a Borrowing Base redetermination or automatic reduction (if required
hereunder), there is sufficient Borrowing Base to permit such reborrowing).”

1.8 Section 2.04(d). Section 2.04(d) of the Credit Agreement is amended to read
as follows:

“(d) Mandatory Prepayments from Certain Sales.

(i) Net Available Cash received by a Loan Party from the Disposition of the
Appalachia Assets shall be prepaid contemporaneously with the closing of any
such Disposition to the extent received by a Loan Party. On the date a Loan
Party Disposes of the Appalachia Assets, (a) the Borrowing Base shall be
automatically reduced by the Borrowing Base Value of the Appalachia Assets (as
determined based upon the most recently delivered Reserve Report) pursuant to
Section 2.02(l(i)) and the Target Amount shall be reduced by the Borrowing Base
Value (so determined) of the Appalachia Assets pursuant to Section 2.15. As of
the First Amendment Effective Date, the Borrowing Base Value of the Appalachia
Assets (as determined based upon the most recently delivered Reserve Report) is
$10,000,000. Net Available Cash received by a Loan Party from the Disposition of
the Appalachia Assets shall be used to prepay outstanding Revolving Loans (or to
Cash Collateralize Letters of Credit, if no Revolving Loans are outstanding) in
an amount at least equal to the excess of Total Outstandings over the Borrowing
Base, to the extent received by a Loan Party. Following any such prepayment and
reduction of the Borrowing Base, any Borrower shall have the right to request a
Borrowing Base redetermination (which right shall be in addition to any
Borrower’s right to request a redetermination of the Borrowing Base pursuant to
Section 2.02(h)). For the avoidance of doubt, any prepayment resulting in Total
Outstandings being less than the Borrowing Base may be reborrowed.

First Amendment to

Amended and

Restated Credit Agreement

--------------------------------------------------------------------------------

(ii) Net Available Cash received by PESC or KPC Pipeline, LLC from the
Disposition of the KPC Pipeline and/or KPC Pipeline, LLC equity shall,
contemporaneously with the closing of any such Disposition, be used to prepay
outstanding Revolving Loans (or to Cash Collateralize Letters of Credit, if no
Revolving Loans are outstanding) to the extent received by a Loan Party. On the
date PESC or KPC Pipeline, LLC Disposes of the KPC Pipeline and/or KPC Pipeline,
LLC equity, the Borrowing Base shall be automatically reduced, dollar for
dollar, by the amount of the Net Available Cash received; provided however that
if, at the time of such prepayment the Target Amount is in effect and (i) the
Total Outstandings are equal to or are less than the Target Amount and (ii) the
Borrowing Base has been reduced to an amount equal to or less than the Target
Amount, then the Borrowing Base will not be automatically reduced.

(iii) Net Available Cash received by CEPM or any PostRock Party from the
Disposition of any or all of the Constellation Equity meeting the requirements
for a Material Disposition shall, contemporaneously with the closing of any such
Disposition, be used to prepay outstanding Revolving Loans (or to Cash
Collateralize Letters of Credit, if no Revolving Loans are outstanding) to the
extent received by CEPM or any PostRock Party. No such prepayment or cash
collateralization will reduce either the Borrowing Base or the Target Amount.”

Agreement is replaced with the figure “$156,450”.

Effective Date is $120,000,000. Upon the sale of any Borrowing Base Oil and Gas
Properties, including the Appalachia Assets, and contemporaneously therewith,
the Target Amount will be reduced by the Borrowing Base Value of such assets.
Neither the sale of the KPC Pipeline or KPC Pipeline, LLC equity nor the
$7,500,000 additional equity investment by White Deer Energy in Parent, which
proceeds shall have been contributed by Parent to PESC pursuant to Section 6.23,
nor the sale of the Constellation Equity will have any effect on the Target
Amount. The Target Amount will be in effect until the effective date of the
first Borrowing Base redetermination following the First Amendment Effective
Date, which is scheduled for October 31, 2012, at which time the Target Amount
will be of no further force or effect and shall cease to have any continuing
significance. Notwithstanding that Total Outstandings under this Agreement may
exceed the Target Amount, the Borrowers shall be entitled to borrow up to the
amount of the Borrowing Base then in effect.”

1.11 Section 5.08. The penultimate sentence of Section 5.08 of the Credit
Agreement is amended to read as follows:

“Upon the proper filing of UCC financing statements, the recording of the
