and the table below reflects activity since the restructuring.

As seen below, from year-end 2011 through year-end 2013, we have invested
$77.5 million of new capital (excluding ARO), produced 1.63 MMboe, and added
3.91 MMboe, which resulted in a Finding and Development Cost of $19.81/Boe.
Production Replacement was 240% during this 24 month period. Year-end 2013
financial and reserve information has not yet been audited.

2013/2014 Production Volumes

In total, 2013 production was 436 Mbo and 1,913 MMcfe or 755 MBoe. On a daily
basis this averaged 2,068 Boe/day and 58% of the production was oil.
Production for the 1st quarter of 2013 averaged 1,801 Boe/day reflecting the
company having just commenced a drilling program at our Leeville field.
Second quarter production averaged 2,606 Boe/day primarily driven by
production increases at our Leeville field. June production peaked at 2,733
Boe/day. Third and fourth quarter production averaged 2,047 Boe/day and 1,817
Boe/day respectively. Production at Leeville, our largest producing field,
was negatively impacted by a non-operated pipeline shut in of approximately 60
days. Additionally, the field operator at the Leeville field changed on
October 1, 2013, and during the transition time from the old to the new
operator production declined due to minimal field maintenance activity.
Normal field maintenance was resumed in December along with the initiation of
another shallow drilling program. Dune completed drilling the Wieting #31 in
the Chocolate Bayou field in the 3rd quarter and commenced production as
previously reported. The reservoir encountered in this wellbore was very
limited and the zone watered out by the end of the 4th quarter. It is
anticipated that the well will be sidetracked in 2014 to encounter the full
reservoir which is included in our year-end reserve report as a PUD location.
Normal declines occurred in our other fields during the third and fourth

With new drilling activity in our Leeville field coming on production during
the first quarter of 2014we anticipate first quarter production to be between
1,900 and 2,200 Boe/day. Depending on capital availability during the quarter
we have several additional drilling and workover opportunities ready to
commence in our other fields. January field level production averaged
approximately 1,900 Boe/day with 35% of this coming from the Leeville field.

Upside Potential

Over and above the 15.5 MMBoe of proved reserves, the company has identified
and additional unrisked51 MMboe of probable, possible, and exploratory
reserves. These projects are defined with recent fully processed 3-D seismic
data and within our acreage positions. The majority of this upside potential
is within our Garden Island Bay field. Capital required to explore and
develop these opportunities is significantly above our current cash flows.
During 2014 we anticipate seeking joint venture partners or outside capitalto
allow the company to participate in drilling these identified upside

2014 Budget

The Company is in the process of developing a risk-adjusted budget that will
fund some exploratory projects in our Garden Island Bay field in addition to a
second development drilling program at our Leeville Field. In addition, we
anticipate redrilling, to approximately 20,200 feet, the deep exploratory well
in the Leeville field that was junked and abandoned last year. Insurance
proceeds will cover substantially all of our cost of drilling this well back
to approximately 19,000 feet where the prior well was lost. This risked
capital budget will be adapted to the constraints of our available capital,
which currently is limited to free cash flow and availability under our
revolver. The revolver availability is currently $47.5 million with $29
million drawn and $2 million of standby letters of credit issued. However,
actual availability is not based solely on the undrawn/unused portion of the
revolver. Borrowing capacity is further limited by the quarterly Debt/EBITDAX
of less than 5.0 to 1.0 for year end 2013 and the first quarter of 2014. The
Debt/EBITDAX covenant will be 4.0 to 1.0 commencing at the end of the second
quarter and going forward in 2014.

James A. Watt, President and CEO of the company stated, "Post the
restructuring late in 2011, we have increased reserves and defined significant
upside opportunities. The potential for organic growth far exceeds our
current cash flow and availability under our revolver. We will continue to
carefully monitor our capital program to achieve maximum production from our
asset base while staying within the constraints of our credit agreements. We
will evaluate potential transactions that can enhance our balance sheet, and
allow for the capital investments necessary to develop the opportunities
within our asset base."
