Existing Loan Agreement shall be hereby amended and modified as follows:

     Section  1.  Defined  Terms.  Each  capitalized  term used  herein  and not

Loan Agreement,  as amended by this Amendment, or if not defined therein, in the
Existing Deed of Trust.  Each  reference in the Existing Loan Agreement to "this
Loan  Agreement"  or "this  Agreement"  shall be deemed to be a reference to the
Existing Loan Agreement, as amended by this Amendment.

     Section 2.  Modification.  The Existing Loan Agreement is hereby amended as

                                       5



          (a) The definition of "Commitment Limit" shall be amended and restated
     to read as  follows:  "$20,000,000,  as  adjusted  pursuant to the terms of
     Section 2.7 and Section 2.9 of this Agreement";

          (b) All references to the "Note" shall mean the Existing Note;

          (c) A new Section 2.10 shall be added to the Original  Loan  Agreement
     that reads as follows:

          "2.10 Unused  Availability  Fee. In addition to interest and all other
          amounts due and payable  pursuant to the terms of this  Agreement  and
          the Note,  Borrower  agrees to pay to Lender an unused facility fee on
          the unused portion of the Commitment Limit (the "unused portion" being
          the amount by which the maximum dollar amount of the Note  (initially,
          $20,000,000)  exceeds the outstanding  principal  balance of the Note)
          from the  Effective  Date  through the Maturity  Date,  at the rate of
          0.25% per annum, accrued daily and payable for each three (3) calendar
          month period (each calendar  quarter),  in arrears,  fifteen (15) days
          after the last day of each calendar  quarter,  with the exception that
          the first  payment  relating to the period ending on February 29, 2012
          shall be due on upon execution of Amendment # 1 to the Loan Agreement.
          The amount of the unused  facility  fee shall be  calculated  each day
          during the  period  for which the fee is due using an assumed  360 day
          year.

          (d) A new  Paragraph (g) shall be added to Section 6.1 of the Existing
     Loan Agreement that reads as follows:

          "(g) as soon as available,  but in any event not later than sixty (60)
          days after the end of the second fiscal quarter of Borrower, a reserve
          report  on  Borrower's  oil and gas  properties  as of the end of such
          fiscal  quarter  prepared  by or audited by a  professional  petroleum
          engineer  approved in advance by Lender which report shall include all
          engineering-relevant  information  as may be  requested by Lender (the
          "Mid-Year Reserve Report")."

          (e) Section 2.7 of the Original Loan Agreement shall be deleted in its
     entirety and replaced with the following:

          "2.7 Adjustment of Commitment Limit or Collateral. Lender shall engage
          a third-party consultant, at the sole cost and expense of Borrower, to
          review (a) the Annual Reserve Report  delivered to Lender  pursuant to
          Section 6.1(c) of this  Agreement and (b) the Mid-Year  Reserve Report
          delivered  to Lender  Pursuant  to Section  6.1(g) of this  Agreement,
          which review shall include preparation of a price-deck  established by
          Lender at PV9 for the purposes of  establishing a new Borrowing  Base.
          If Lender delivers to Borrower written  notification that, in Lender's

                                       6



          sole  discretion,  the new Borrowing Base does not provide  sufficient
          collateral to support  Advances up to the Commitment  Limit,  then the
          Commitment Limit shall be immediately  reduced to such an amount as is
          supported by the adjusted Borrowing Base. Provided,  however, that, in
          the event the Borrowing Base is reduced  pursuant to this Section 2.7,
          Borrower may pledge  additional  assets as Collateral to Lender as may
          be necessary,  in Lender's sole discretion,  to support an increase in
          the Commitment  Limit back to  $20,000,000,  and the Commitment  Limit
          shall  be so  adjusted  following  documentation  of  such  pledge  of
          additional assets as Collateral,  such  documentation to be determined
          in the reasonable discretion of Lender. Provided, further that, if the
          Commitment  Limit has been  reduced  pursuant  to this  Section 2.7 or
          pursuant to Section  2.9 and in  subsequent  years the Annual  Reserve
          Report or the Mid-Year  Reserve Report  displays a Borrowing Base that
          would  support  a  Commitment  Limit  greater  than the  then-existing
          Commitment  Limit,  then the Commitment Limit shall be increased to an
          amount  (not to  exceed  $20,000,000)  that,  in  Lender's  reasonable
          discretion,  would  be  supported  by the  information  regarding  the
          Collateral contained in such Annual Reserve Report."

          (f) A new Section 2.11 shall be added to the Existing  Loan  Agreement
     that reads as follows:

          "2.10 Other  Credit  Available  to  Borrower.  Any and all  additional
          commitments by Lender to extend credit to Borrower  (including  credit
          cards,  etc.) shall serve to reduce the credit  available for Advances
          pursuant  to  this  Agreement  or the  Note  by  the  amount  of  such
          additional commitments."

          (g) The  following  definitions  shall be added to Section  8.1 of the
     Existing Loan Agreement:

          "`Current  Assets'  means,  as of the  period  of  determination,  all
          current assets of Borrower,  excluding all receivables aged 90 days or
          longer and including all unfunded borrowing  availability  pursuant to
          the terms of this Agreement."

          "`Current  Liabilities' means, as of the period of determination,  all
          current  liabilities of Borrower,  excluding all current maturities of
          amounts due pursuant to the terms of this Agreement or the Note."

          (g) A new Section 8.5 shall be added to the  Existing  Loan  Agreement
     that reads as follows:

          "8.5 Current Ratio. Borrower shall maintain a Current Ratio of no less
          than  1.00,  calculated  at the  end of  each  fiscal  quarter,  where
          "Current  Ratio" is  calculated as Current  Assets  divided by Current
          Liabilities."

                                       7




It is the intent of this  Amendment  that the  obligations of the Borrower under
the Existing  Loan  Agreement  shall be entitled to the benefits and  collateral
security  under the Existing Deed of Trust as fully as if such  obligations  had
been incurred under the Original Loan Agreement as originally in effect.

     Section 3. Third Party Costs and Expenses. All reasonable third party costs
and expenses of Lender related to or arising from the increase of the Commitment
Limit and the amendment to the Loan Documents,  including,  without  limitation,
any and all legal  fees,  valuations,  reviews,  surveys,  reports,  filings and
recordation  fees, shall be the sole  responsibility  of Borrower,  and shall be
payable to Lender  upon  demand,  and if not so paid,  shall  become part of the
Obligation  (as defined in the Existing Loan  Agreement) and shall bear interest
at the Default  Rate  beginning on the date demand for payment is made by Lender
until the date paid by Borrower.

     Section 4. Facility Fee. Upon the date hereof,  Borrower shall pay Lender a
commitment fee of Twelve Thousand and Five Hundred Dollars  ($12,500.00)  (0.25%
of the $5,000,000 increase in the Commitment Limit).

     Section 5.  Representations and Warranties.  The Borrower hereby represents
and warrants that the  representations and warranties made by it in the Original
Loan  Agreement are true and complete on and as of the date hereof as if made on
and as of the date hereof.

     Section 6. Covenants.  The Borrower hereby  covenants and agrees to perform
each and every duty and  obligation  of the  Borrower  contained in the Existing
Loan Agreement as amended by this Amendment.

     Section 7.  Effectiveness.  This Amendment shall be effective as of the day
and year first  written  above upon its  execution and delivery by the Borrower.
Except as herein  provided,  the Existing Loan Agreement shall remain  unchanged
and in full force and effect.

     Section 8.  Counterparts.  This  Amendment may be executed in any number of
counterparts,  each of which shall be deemed an original  and all of which shall
constitute one instrument.
