                               Notes to Financial Statements

1.  The interim financial data is unaudited; however, in our opinion, it
    includes all adjustments, consisting only of normal recurring adjustments
    necessary for a fair statement of the results for the interim periods.
    The financial statements included herein have been prepared pursuant to
    the SEC's rules and regulations; accordingly, certain information and
    footnote disclosures normally included in GAAP financial statements have
    been condensed or omitted.

2.  Our organization and business, the accounting policies we follow and other
    information are contained in the notes to our financial statements filed
    as part of our 2002 Form 10-KSB.  This quarterly report should be read in
    conjunction with that annual report.



3. In July 2001, the Financial Accounting Standards Board issued SFAS No. 143,
   "Accounting for Asset Retirement Obligations."  SFAS No. 143 requires
   entities to record the fair value of a liability for an asset retirement
   obligation in the period in which it is incurred and a corresponding
   increase in the carrying amount of the related long-lived asset and is
   effective for fiscal years beginning after June 15, 2002.  We adopted
   SFAS No. 143 on January 1, 2003 and increased our liability for asset
   retirement obligations by $264,000 (using an 8% discount rate) and
   recorded a cumulative effect of change in accounting principle of $181,000.
   For the six months ended June 30, 2003, we recognized $37,000 of accretion
   on the liability as a component of depletion expense.

   Had SFAS No. 143 been adopted on January 1, 2002, the pro forma net loss
   would have been $1,147,000 and the pro forma net loss per share would have
   been $(.16) for the six months ended June 30, 2002 and the pro forma asset
   retirement obligation at January 1, 2002 would have been $850,000.

4. As allowed in SFAS No. 123, "Accounting for Stock-Based Compensation,"
   we continue to apply Accounting Principles Board Opinion (APB) No. 25,
   "Accounting for Stock Issued to Employees," and related interpretations
   in recording compensation related to our plan.  The supplemental
   disclosures required by SFAS No. 123, as amended in SFAS No. 148,
   "Accounting for Stock-Based Compensation - Transition and Disclosure,"
    related to our stock option plan are presented below.

   Under SFAS No. 123, compensation cost would be recognized for the fair
   value of the employee's option rights. The fair value of each option was
   estimated on the date of grant using the Black-Scholes option-pricing model
   with the following assumptions for option grants made in 2002 (there were

5. Through mid February 2003, we had never entered into any commodity
   derivative agreements since acquiring the SC Field.  During mid February
   2003 oil prices in the field reached a level of about $36 per barrel.
   For the first time we purchased puts on 23,000 barrels of oil for the
   month of June 2003 (strike price of $29.00 per barrel) and 16,500 barrels
   of oil for the month of July 2003 (average strike price of $30.48 per
   barrel).  Our total investment was $83,000.  At March 31, 2003 the fair
   value of these puts was $140,000.  During the second quarter we sold the
   puts for $122,000.  Our net gain from this transaction was $39,000.  For
   accounting purposes we realized a gain of $57,000 in the first quarter and
   in the second quarter we recognized a loss of $18,000.

6. As discussed in previous filings, the SC Field was purchased from ARCO
   (Atlantic Richfield which is now part of BP p.l.c.) in May 1990.  As part
   of the Purchase and Sale Agreement,  ARCO agreed to indemnify us for
   certain environmental liabilities connected with their 40-year ownership of
   the field and gas plant ("ARCO Indemnity").  Part of the gas plant has not
   been operational during the past twenty-five years.  There is evidence of
   asbestos in the non-operational part of the gas plant.  It is our position,
   and the opinion of our legal counsel, that the ARCO Indemnity covers future
   abandonment and clean-up costs associated with this gas plant.  We have had
   several discussions with BP regarding this matter and have retained a San
   Francisco law firm to assert our rights under the ARCO Indemnity.  BP
   continues to deny any responsibility.

   The costs to abandon and clean up the gas plant area and other oil and gas
   areas at the field will be significant.  There is a chance, depending on
   the negotiations and legal proceedings with BP, that some or all of the
   costs could be borne by us.  At this time we are unable to estimate what
   these costs could ultimately be but we expect that such costs could have a
   material adverse effect on our financial condition, results of operations
   and cash flows.

Oil and gas revenue increased due to higher prices as set forth in the
Table above.  Decrease in other gas production was due to the significant
Production decline in our South Texas - Bonus field.  As previously
disclosed, we took an impairment charge of $840,000 in the second quarter
of 2002 for this field.

Current prices for the South Cuyama field are about $29.42 for oil and
$5.00 for gas and San Juan gas is about $4.40.

The table below (in thousands) shows lease operating expenses (LOE) for
our two primary fields.

LOE in the field increased due to higher operating expenses relating to
the new equipment we had to install in the first quarter of 2003 in order
to remove CO2 from our gas stream.  Furthermore, when oil prices are high,
we perform more repair and maintenance in the field compared to when
prices are low (see the table above for 2003 and 2002 average oil prices.)

The increase in exploration costs was due primarily to a late billing for
$64,000 relating to 3-D work performed in the fourth quarter 2002.

The increase in G&A was due to higher 2002 audit and tax fees - $35,000,
accruals for 2003 audit and tax fees - $25,000, higher employee costs -
$32,000, higher legal fees associated with the ARCO Indemnity and SOCAL
negotiations - $24,000, and other minor increases of $19,000.

DD&A decreased due to higher reserve estimates at June 30, 2003 compared
to June 30, 2002.  The increase in reserves was due to higher oil prices.

quarter-to-date comparisons, other than for G&A.

LIQUIDITY AND CAPITAL RESOURCES
-------------------------------

Cash and cash flow from operations are expected to enable us to meet our
obligations as they become due during the next several years.

     Bank Debt
     ---------

The SC Field, our principal asset, is pledged to U. S. Bank National
Association under a $2,200,000 revolving line of credit which was renewed
on March 31, 2002.  At March 31, 2003 we owed $244,000 under this line.
On April 28, 2003 the loan was paid off.

THE FOLLOWING DISCUSSION UPDATES THE MD&A CONTAINED IN ITEM 6 OF THE 2002
FORM 10-KSB AND THE TWO DISCUSSIONS SHOULD BE READ TOGETHER.

PROSPECT DEVELOPMENT AND EXPLORATION ACTIVITY
---------------------------------------------

     South Cuyama Field
     -------------------

Based on the results of our 3-D project we have identified four
wildcat sites located outside the field boundaries.  Also, we have
identified six developmental drilling opportunities within the boundaries
of the field.  During July 2003 we drilled three development wells.  We
are still in the process of perforating and production testing.  It is too
early to assign reserves to these wells, but the results are encouraging.
The wildcat wells outside the field will not be drilled until sometime next
year and no further development drilling is planned for this year.

     SOCAL
     -----

Currently gas sales in the SC Field are 1,000 MCF per day.  Southern
California Gas Company (SOCAL), the pipeline company and our only outlet to
sell gas has imposed a 1,000 MCF per day maximum limit.  If it weren't for
this limit, we believe we could sell 1,800 MCF per day.  If we are unable to
sell more gas, we will have to curtail our exploration and development plans.
We have been negotiating with SOCAL to increase the capacity from 1,000 MCF
per day to 3,000 MCF per day.  We should know in the next 30 days the results
of these negotiations.

ARCO Indemnity
--------------

As discussed in previous filings, the SC Field was purchased from ARCO
(Atlantic Richfield which is now part of BP p.l.c.) in May 1990.  As part of
the Purchase and Sale Agreement,  ARCO agreed to indemnify us for certain
environmental liabilities connected with their 40-year ownership of the field
and gas plant ("ARCO Indemnity").  Part of the gas plant has not been
operational during the past twenty-five years.  There is evidence of
asbestos in the non-operational part of the gas plant.  It is our position,
and the opinion of our legal counsel, that the ARCO Indemnity covers future
abandonment and clean-up costs associated with this gas plant.  We have had
several discussions with BP regarding this matter and have retained a San
Francisco law firm to assert our rights under the ARCO Indemnity.  BP continues
to deny any responsibility.

The costs to abandon and clean up the gas plant area and other oil and gas areas
at the field will be significant.  There is a chance, depending on the
negotiations and legal proceedings with BP, that some or all of the costs could
be borne by us.  At this time we are unable to estimate what these costs could
ultimately be but we expect that such costs could have a material adverse effect
on our financial condition, results of operations and cash flows.

     San Juan Basin - New Mexico
     ---------------------------

Two successful development gas wells were drilled during April.  In July and
August, we drilled three more successful development gas wells.  These five
wells cost about $3 million to the 100%.  We have an approximate 10% WI in
these five wells.  We expect to assign proved developed gas reserves to the
100% of between 1 BCF and 1.5 BCF per well.  Our net revenue interest in these
wells is about 6%.  One more development gas well is planned before the end of
the year and that will conclude our development activity in this area.

Crude Oil Put Options
---------------------

Through mid February 2003, we had never entered into any commodity derivative
agreements since acquiring the SC Field.  During mid February 2003 oil prices
in the field reached a level of about $36 per barrel.  For the first time we
purchased puts on 23,000 barrels of oil for the month of June 2003 (strike
price of $29.00 per barrel) and 16,500 barrels of oil for the month of July
2003 (average strike price of $30.48 per barrel).  Our total investment was
$83,000.  At March 31, 2003 the fair value of these puts was $140,000.
During the second quarter we sold the puts for $122,000.  Our net gain from
this transaction was $39,000.  For accounting purposes we realized a gain of
$57,000 in the first quarter and in the second quarter we recognized a loss
of $18,000.

Predecessor Entity
------------------

Over the past 12 years we have paid about $200,000 to properly plug and abandon
12 or so sites which were previously plugged and abandoned by Kimbark Oil & Gas
Company, our predecessor entity. For the six months ended June 30, 2003 and
2002, we have spent less than $2,000 for these type of costs.  We do not expect
any more notices from state regulatory jurisdictions regarding improperly P&A
wells, but it is possible that there could be more.

SFAS No. 143 - "Accounting for Asset Retirement Obligations"
------------------------------------------------------------

In July 2001, the Financial Accounting Standards Board issued SFAS No. 143,
"Accounting for Asset Retirement Obligations."  SFAS No. 143 requires entities
to record the fair value of a liability for an asset retirement obligation in
the period in which it is incurred and a corresponding increase in the carrying
amount of the related long-lived asset and is effective for fiscal years
beginning after June 15, 2002.  We adopted SFAS No. 143 on January 1, 2003 and
increased our liability for asset retirement obligations by $264,000 (using an
8% discount rate) and recorded a cumulative effect of change in accounting
principle of $181,000.  For the six months ended June 30, 2003, we
recognized $37,000 of accretion on the liability as a component of depletion
expense.

There are no other significant changes or developments to report from what we
disclosed in the 2002 Form 10-KSB.

ITEM 3. CONTROLS AND PROCEDURES

We maintain a system of disclosure controls and procedures that are designed
for the purposes of ensuring that information required to be disclosed in our
SEC reports is recorded, processed, summarized and reported within the time
periods specified in the SEC's rules and forms, and that such information is
accumulated and communicated to our CEO as appropriate to allow timely
decisions regarding required disclosure.

As of the end of the period covered by this report, we have carried out an
evaluation, under the supervision and with the participation of our CEO of the
effectiveness of the design and operation of our disclosure controls and
procedures. Based upon that evaluation, our CEO, who is also our CFO, concluded
that our disclosure controls and procedures are effective for the purposes
discussed above. There have been no significant changes in our internal
controls or in other factors that could significantly affect these controls
subsequent to the date of the evaluation.
