(b)  All interest will be computed on the actual number of days elapsed over a
year comprised of 360 days. Interest will be due and payable in immediately
available funds on the Maturity Date.

(b)

Section 2.6(a) of the Credit Agreement is amended by deleting the existing
Section 2.6(a) in its entirety and replacing it with the following:

(a)

Payment of Obligations.

(i)

On each Payment Date, Borrower will, subject to Section 2.8(a), pay to Lender
the Applicable Percentage of Net Operating Cash Flow to be applied as set forth
in Section 2.6(c).  All interest on the outstanding principal balance of the
Term Loan from the Closing Date through the last day of the month immediately
preceding the first Payment Date will be due and payable on the first Payment
Date.  On each subsequent Payment Date, interest will be due and payable on the
outstanding principal balance of the Term Loan for the immediately preceding
month, and Borrower will pay to Lender the Applicable Percentage of Net
Operating Cash Flow to be applied against the entire outstanding balance of the
Term Loan (including accrued interest) in the order set forth in Section 2.6(c),
subject to Section 6.21.  In no event shall payments made to Lender on any
Payment Date be less than the interest accrued and payable on the outstanding
balance of the Term Loan through the applicable Payment Date.

(ii)

On each Payment Date, Borrower shall make monthly mandatory principal reduction
payments with respect to the Obligations (in addition to any other payments or
prepayments of principal and interest due under this Agreement) (A) in an amount
equal to One Hundred Thousand Dollars ($100,000) during the period beginning
August 20, 2010, and continuing through September 20, 2010, and (B) in an amount
equal to Two Hundred and Fifty Thousand Dollars ($250,000) during the period
beginning on September 21, 2010, and continuing through the earlier of repayment
of all the Obligations or the Maturity Date.  The payment set forth above in
this Section 2.6(a)(ii) shall be an aggregate payment combined with payment
under Section 2.6(a)(ii) of the Amber Credit Agreement, such that the total
payment under the Amber Credit Agreement and this Agreement equals the amount
set forth above in this Section 2.6(a)(ii).  Provided, however, Borrower shall
be entitled to a credit of any amounts received by Lender under Section 2.10
against any future payments due under this Section 2.6(a)(ii).

(c)

Section 2.8 of the Credit Agreement is amended by adding the following new
subsections (d) and (e):

(d)

As of the date of the Second Amendment, the total amount of cash collateral in
the Project Account is zero.  

2

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

(e)

Subject to Section 2.8(c), but notwithstanding any other term or provision of
this Section 2.8, on the Maturity Date and at any time a Default exists,
Borrower authorizes and directs Lender to apply any or all of the amounts then
credited to the Project Account against the Obligations in accordance with
Section 2.6(c).  Whenever Lender exercises its rights under this Section 2.8(e),
if Borrower has not previously provided to Lender satisfactory documentation of
amounts to be remitted to Borrower under Section 2.8(c), then Lender can make a
good faith estimate of such amounts subject to adjustment upon receipt of
acceptable documentation from Borrower.

(d)

Section 2.10 of the Credit Agreement is amended by deleting the existing Section
2.10 in its entirety and replacing it with the following:

Section 2.10  Mandatory Prepayment of the Term Loan.

(a)  Borrower shall promptly pay to Lender one hundred percent (100%) of all net
proceeds from the sale of any Collateral (excluding sales of Hydrocarbons in the
ordinary course of business and the sale of Equipment pursuant to the Security
Agreement).  The preceding sentence will not be deemed to be a consent by Lender
to any sale.  Any prepayments shall have no effect on the Net Profits Overriding
Royalty Interest Conveyance granted to any Lender, or the rights of such Lender
with respect to the Net Profits Overriding Royalty Interest.  For the avoidance
of any doubt, proceeds from a farmout or similar agreement approved in writing
in advance by Lender shall not be subject to this Section 2.10(a).

(b)  Borrower shall promptly pay to Lender any cash amounts received as
insurance proceeds under any property or casualty insurance in relation to any
portion of the Collateral.

(c)  Borrower shall promptly pay to Lender an amount in cash equal to one-sixth
(1/6th) of the gross proceeds received by Borrower or any of its Affiliates as a
result of equity investments in Borrower or any of its Affiliates by any Person.
 For the avoidance of doubt, such payment of one-sixth (1/6th) of the gross
proceeds of any equity investment set forth above in this Section 2.10(c) shall
be calculated on an aggregate basis with the payment under Section 2.10(d) of
the Amber Credit Agreement, such that the aggregate total payment under the
Amber Credit Agreement and this Agreement equals no more than one-sixth (1/6th)
of the total gross proceeds of any equity investment.

(e)  All amounts paid by Borrowers to Lender under this Section 2.10 will be
immediately applied as a prepayment of the Loans in accordance with Section
2.6(c).

(e)

Article X of the Credit Agreement is amended by deleting the existing Section
10.1(a) and replacing it with the following:

(a)

Borrower fails to make any payment under this Agreement, the Term Note, any
Security Document or the Guaranty on the date due;

(f)

Article X of the Credit Agreement is amended by adding the following new
subsection (x) to Section 10.1:

(x)

the occurrence of a “default” or an “Event of Default” under any of the Amber
Loan Documents that continues beyond any applicable grace period;

3.

Limited Waiver of Defaults.  Lender hereby waives any Default or Event of
Default existing under any of the Loan Documents immediately prior to the
execution and delivery of this Amendment.  Notwithstanding the previous
sentence, however, NOTHING IN THIS AMENDMENT WILL BE CONSTRUED TO CONSTITUTE A
WAIVER BY LENDER OF ANY FUTURE DEFAULT OR EVENT OF DEFAULT BY BORROWER OR ANY
OTHER PERSON UNDER THE CREDIT AGREEMENT (AS AMENDED HEREBY) OR ANY OF THE OTHER
LOAN DOCUMENTS.  NOTHING HEREIN SHALL BE CONSTRUED TO WAIVE ANY RIGHTS OR
REMEDIES AVAILABLE TO LENDER OR ITS AFFILIATES PURSUANT TO THE CREDIT AGREEMENT,
OTHER LOAN DOCUMENTS, THE COMPANY AGREEMENT, OR BY OPERATION OF LAW OR OTHERWISE
(WHICH RIGHTS SHALL BE CUMULATIVE) AS A RESULT OF ANY FUTURE DEFAULT OR EVENT OF
DEFAULT.  

4.

The Obligations.  Borrower and each of the other Obligors agree and acknowledge
that, as of July 28, 2010, (a) the principal amount outstanding under the Term
Note is One Million Two Hundred Twenty-Three Thousand Three Hundred Nine Dollars
and Sixty-Five Cents ($1,223,309.65), (b) the amount of unpaid and accrued
interest on the Term Note is One Hundred Twenty-One Thousand Three Hundred
Sixty-Seven Dollars and Five Cents ($121,367.05), and (c) no defense or right of
set off exists with respect to the enforceability of any of the Obligations.

3

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

5.

Default Interest Rate.  For the avoidance of any doubt and in accordance with
the email dated September 17, 2009, pursuant to which Lender notified Borrower
that a payment default exists and is continuing under the Credit Agreement (the
“Default Notice”), interest shall continue to accrue at the Default Rate and to
the extent that interest due and payable is not satisfied by the cash flow sweep
provisions of Section 2.8 of the Credit Agreement, interest shall, each month,
be capitalized as principal and bear interest at the Default Rate until the
Maturity Date set forth in this Amendment at which time all principal and
accrued and unpaid interest shall be due and payable.

counterpart, each of which shall be deemed an original, and all of which
constitute, collectively, one instrument; but, in making proof of this
instrument, it shall not be necessary to produce or account for more than one
such counterpart.  It shall not be necessary for Borrower and Lender to execute
the same counterpart hereof so long as Borrower and Lender each execute a
counterpart hereof.  For purposes of this Amendment, an electronic copy of any
party’s signature to this Amendment shall be deemed an original signature.

12.

Governing Law.  This Amendment and all transactions provided for in this
Amendment will be governed by, interpreted and construed under and enforced
pursuant to the laws of the State of Texas, without regard to its conflicts of
laws provisions.

13.

FINAL AGREEMENT.  THE LOAN DOCUMENTS, AS AMENDED BY OR IN CONNECTION WITH THIS
AMENDMENT, REPRESENT THE FINAL AGREEMENT BETWEEN THE PARTIES AND MAY NOT BE
CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS OR SUBSEQUENT ORAL AGREEMENTS
