Basic  earnings  per common  share is based on the  weighted  average  number of
shares of common  stock  outstanding  during the periods.  Diluted  earnings per
common share is based on the weighted  average  number of common  shares and all
dilutive potential common shares outstanding during the periods. The Company had
outstanding  146,500 and 35,500  stock  options  and 252,632 and zero  warrants,
respectively,   during  the  three   months   ended  June  30,  2003  and  2004,
respectively,  which were  antidilutive and were not included in the calculation
because the exercise price of these  instruments  exceeded the underlying market
value of the options and  warrants.  The  Company  had  outstanding  156,500 and
50,500 stock options and 252,632 and zero  warrants  during the six months ended
June 30,  2003 and 2004,  respectively,  which  were  antidilutive  because  the
exercise price of these instruments  exceeded the underlying market value of the
options and warrants.  At June 30, 2003 and 2004, the Company also had 1,202,791
and zero shares,  respectively,  based on the assumed conversion of the Series B
Convertible  Participating  Preferred Stock, that were antidilutive and were not
included in the calculation.

On May 24, 2002,  the Company  entered  into a credit  agreement  with  Hibernia
National Bank (the "Hibernia  Facility")  which matures on January 31, 2006, and
repaid its existing  facility  with Compass Bank (the "Compass  Facility").  The
Hibernia Facility provides a revolving line of credit of up to $30.0 million. It
is secured by substantially all of the Company's assets and is guaranteed by the
Company's subsidiary.

The  borrowing  base  will be  determined  by  Hibernia  National  Bank at least
semi-annually  on each October 31 and April 30. The initial  borrowing  base was
$12.0 million.  Each party to the credit  agreement can request one  unscheduled
borrowing base  determination  subsequent to each scheduled  determination.  The
borrowing  base  will at all  times  equal  the  borrowing  base  most  recently
determined by Hibernia  National Bank, less quarterly  borrowing base reductions
required subsequent to such determination. Hibernia National Bank will reset the
borrowing  base amount at each  scheduled and each  unscheduled  borrowing  base
determination  date.  The initial  quarterly  borrowing  base  reduction,  which
commenced on June 30, 2002,  was $1.3  million.  The  quarterly  borrowing  base
reduction effective July 31, 2004 was $2.5 million.

On December 12, 2002,  the Company  entered into an Amended and Restated  Credit
Agreement  with Hibernia  National Bank that  provided  additional  availability
under the Hibernia Facility in the amount of $2.5 million which is structured as
an  additional  "Facility  B" under the Hibernia  Facility.  The Facility B bore
interest  at LIBOR  plus  3.375%,  was  secured by  certain  leases and  working
interests in oil and natural gas wells and matured on April 30,  2003.  As such,
the total borrowing base under the Hibernia Facility as of December 31, 2003 and
June 30, 2004 was $19.0 million and $26.0 million,  respectively,  of which $7.0
and $9.0 million, respectively, was drawn on the Hibernia Facility.

If the  principal  balance of the Hibernia  Facility  ever exceeds the borrowing
base as reduced by the quarterly  borrowing base reduction (as described above),
the principal balance in excess of such reduced borrowing base will be due as of
the date of such reduction.  Otherwise, any unpaid principal or interest will be
due at maturity.

If the principal balance of the Hibernia Facility ever exceeds any re-determined
borrowing  base, the Company has the option within thirty days to  (individually
or in  combination):  (i) make a lump sum payment  curing the  deficiency;  (ii)
pledge additional  collateral  sufficient in Hibernia National Bank's opinion to
increase the borrowing base and cure the deficiency; or (iii) begin making equal
monthly  principal  payments  that will cure the  deficiency  within the ensuing
six-month  period.  Such  payments are in addition to any payments that may come
due as a result of the quarterly borrowing base reductions.

For each tranche of principal  borrowed under the revolving line of credit,  the
interest rate will be, at the Company's option: (i) the Eurodollar Rate, plus an
applicable  margin  equal to 2.375% if the amount  borrowed  is greater  than or
equal to 90% of the  borrowing  base,  2.0% if the amount  borrowed is less than
90%, but greater than or equal to 50% of the  borrowing  base,  or 1.625% if the
amount  borrowed is less than 50% of the borrowing  base; or (ii) the Base Rate,
plus an  applicable  margin of 0.375% if the amount  borrowed is greater than or
equal to 90% of the borrowing base.  Interest on Eurodollar  Loans is payable on
either the last day of each  Eurodollar  option period or monthly,  whichever is
earlier. Interest on Base Rate Loans is payable monthly.

The  Company is subject to  certain  covenants  under the terms of the  Hibernia
Facility,  including,  but  not  limited  to the  maintenance  of the  following
financial  covenants:  (i) a  minimum  current  ratio  of 1.0 to 1.0  (including
availability  under the borrowing base),  (ii) a


                                       7


minimum  quarterly  debt  services  coverage of 1.25 times,  and (iii) a minimum
shareholders  equity equal to $56.0 million,  plus 100% of all subsequent common
and  preferred  equity  contributed  by  shareholders,  plus 50% of all positive
earnings  occurring   subsequent  to  such  quarter  end,  all  ratios  as  more
particularly discussed in the credit facility. The Hibernia Facility also places
restrictions   on   additional   indebtedness,    dividends   to   non-preferred
stockholders,  liens, investments,  mergers,  acquisitions,  asset dispositions,
asset pledges and  mortgages,  change of control,  repurchase or redemption  for
cash  of  the  Company's  common  or  preferred  stock,   speculative  commodity
transactions, and other matters.

At December 31, 2003 and June 30, 2004,  amounts  outstanding under the Hibernia
Facility totaled $7.0 million and $9.0 million, respectively, with an additional
$12.0 million and $17.0 million, respectively,  available for future borrowings.
At  December  31,  2003 and June 30,  2004,  one letter of credit was issued and
outstanding under the Hibernia Facility in the amount of $0.2 million.

On June 29, 2001, CCBM, Inc., a wholly owned subsidiary of the Company ("CCBM"),
issued a non-recourse  promissory  note payable in the amount of $7.5 million to
RMG as consideration for certain interests in oil and natural gas leases held by
RMG in Wyoming  and  Montana.  The RMG note is payable in  41-monthly  principal
payments of $0.1 million plus interest at 8% per annum  commencing July 31, 2001
with the balance due December 31, 2004. The RMG note is secured solely by CCBM's
interests  in the  oil and  natural  gas  leases  in  Wyoming  and  Montana.  In
connection  with the Company's  investment in Pinnacle Gas Resources,  Inc., the
Company  received  a  reduction  in the  principal  amount  of the  RMG  note of
approximately  $1.5  million  and  relinquished  the right to  certain  revenues
related to the properties contributed to Pinnacle.  During the second quarter of
2004,  CCBM,  Inc.,  relinquished  a portion of its interests in certain oil and
natural gas leases and reduced the principal due on the note by $0.3 million.

In December 2001, the Company entered into a capital lease agreement  secured by
certain production equipment in the amount of $0.2 million. The lease is payable
in one payment of $11,323 and 35 monthly payments of $7,549  including  interest
at 8.6% per annum.  In October  2002,  the Company  entered into a capital lease
agreement secured by certain production equipment in the amount of $0.1 million.
The lease is payable in 36 monthly payments of $3,462 including interest at 6.4%
per annum.  In May 2003,  the Company  entered  into a capital  lease  agreement
secured by certain production equipment in the amount of $0.1 million. The lease
is payable in 36  monthly  payments  of $3,030  including  interest  at 5.5% per
annum.  In August  2003,  the Company  entered  into a capital  lease  agreement
secured by certain production equipment in the amount of $0.1 million. The lease
is payable in 36  monthly  payments  of $2,179  including  interest  at 6.0% per
annum.  The Company has the option to acquire the equipment at the conclusion of
the lease for $1 under all of these leases.  DD&A on the capital  leases for the
three  months  ended June 30, 2003 and 2004  amounted  to $11,000  and  $12,000,
respectively.  DD&A on the capital leases for the six months ended June 30, 2003
and 2004 amounted to $20,000 and $24,000,  respectively, and accumulated DD&A on
the leased  equipment at December 31, 2003 and June 30, 2004 amounted to $76,000
and $100,000, respectively.

In December 1999, the Company  consummated  the sale of $22.0 million  principal
amount of 9% Senior  Subordinated Notes due 2007 (the "Subordinated  Notes") and
$8.0 million of common stock and Warrants.  The Company sold $17.6 million, $2.2
million,  $0.8  million,  $0.8  million  and $0.8  million  principal  amount of
Subordinated Notes; 2,909,092,  363,636,  121,212, 121,212 and 121,212 shares of
the Company's  common stock and 2,208,152,  276,019,  92,006,  92,006 and 92,006
Warrants to CB Capital  Investors,  L.P.  (now known as JPMorgan  Partners  (23A
SBIC),  L.P.),  Mellon Ventures,  L.P., Paul B. Loyd, Jr., Steven A. Webster and
Douglas  A.P.  Hamilton,  respectively.  The  Subordinated  Notes were sold at a
discount of $0.7 million,  which is being  amortized over the life of the notes.
Interest  payments are due quarterly  commencing on March 31, 2000.  The Company
may elect, until December 2004, to increase the amount of the Subordinated Notes
for 60% of the interest which would otherwise be payable in cash. As of December
31, 2003 and June 30, 2004, the outstanding  balance of the  Subordinated  Notes
had been  increased  by $5.3  million and $6.0  million  respectively,  for such
interest  paid in kind.  During  the six  months  ended  June 30,  2004,  Mellon
Ventures,  L.P.,  JPMorgan Partners (23A SBIC), Steven A. Webster and Douglas A.
P. Hamilton exercised warrants to purchase 276,019, 2,208,152, 92,006 and 92,006
shares of common stock,  respectively,  on a cashless exercise basis for a total
of 205,692,  1,684,949,  70,205 and 70,205 shares of common stock, respectively,
and Paul B. Loyd, Jr.,  exercised warrants to purchase 92,006 shares for a total
of 92,006 shares of common stock.  As a result,  no warrants to purchase  shares
remain outstanding from the warrants originally issued in December 1999.

On June 7, 2004, an unaffiliated third party (the "Purchaser") purchased all the
outstanding Subordinated Notes from the original note holders. In exchange for a
$0.4 million  amendment fee,  certain terms and  conditions of the  Subordinated
Notes were amended, to provide for, among other things, (1) a one year extension
of the maturity to December 15, 2008, (2) a one year extension, through December
15, 2005, of the paid-in-kind  ("PIK") interest option to pay-in-kind 60% of the
interest due each period by increasing  the  principal  balance by a like amount
(the "PIK  option"),  (3) an additional one year option to extend the PIK option
through  December 15, 2006 at an annual  interest rate on the deferred amount of
10% and the  payment  of a  one-time  fee  equal to 0.5% of the  principal  then
outstanding  and  (4)  additional  flexibility  to  obtain  a  separate  project
financing  facility in the future.  The amendment fee will be amortized over the
remaining life of the Note.



                                       8


The Company is subject to certain  covenants under the terms of the Subordinated
Notes  securities  purchase  agreement,   including  but  not  limited  to,  (a)
maintenance  of a specified  tangible net worth,  (b)  maintenance of a ratio of
EBITDA  (earnings  before interest,  taxes,  depreciation  and  amortization) to
quarterly  Debt Service (as defined in the  agreement)  of not less than 1.00 to
1.00,  (c) a limitation  of its capital  expenditures  to an amount equal to the
Company's  EBITDA for the immediately  prior fiscal year (unless approved by the
Company's Board of Directors and a JPMorgan  Partners,  LLC appointed  director)
and (d) a limitation  on our Total Debt (as defined in the  securities  purchase
agreement) to 3.5 times EBITDA for any twelve month period.

At June 30, 2004, the Company was in compliance with all of its debt covenants.

5. INVESTMENT IN PINNACLE GAS RESOURCES, INC.

The Pinnacle Transaction

On June 23, 2003,  pursuant to a Subscription and Contribution  Agreement by and
among the Company and its wholly-owned  subsidiary,  CCBM, Inc. ("CCBM"),  Rocky
Mountain Gas, Inc.  ("RMG") and the Credit  Suisse First Boston  Private  Equity
entities,  named therein (the "CSFB  Parties"),  CCBM and RMG contributed  their
respective  interests,  having a  estimated  fair  value of  approximately  $7.5
million each, in (1) leases in the Clearmont,  Kirby,  Arvada and Bobcat project
areas and (2) oil and natural gas reserves in the Bobcat project area to a newly
formed   entity,   Pinnacle  Gas   Resources,   Inc.,  a  Delaware   corporation
("Pinnacle").  In exchange for the  contribution  of these assets,  CCBM and RMG
each received 37.5% of the common stock of Pinnacle ("Pinnacle Common Stock") as
of the closing date and options to purchase  Pinnacle  Common  Stock  ("Pinnacle
Stock Options"). CCBM no longer has a drilling obligation in connection with the
oil and natural gas leases contributed to Pinnacle.

Simultaneously   with  the  contribution  of  these  assets,  the  CSFB  Parties
contributed  approximately  $17.6  million of cash to Pinnacle in return for the
Redeemable  Preferred Stock of Pinnacle ("Pinnacle Preferred Stock"), 25% of the
Pinnacle  Common Stock as of the closing date and warrants to purchase  Pinnacle
Common Stock ("Pinnacle  Warrants").  The CSFB Parties also agreed to contribute
additional  cash,  under certain  circumstances,  of up to  approximately  $11.8
million to Pinnacle to fund future drilling,  development and acquisitions.  The
CSFB Parties currently have greater than 50% of the voting power of the Pinnacle
capital  stock  through  their  ownership of Pinnacle  Common Stock and Pinnacle
Preferred Stock.

Immediately following the contribution and funding,  Pinnacle used approximately
$6.2  million of the  proceeds  from the funding to acquire an  approximate  50%
working interest in existing leases and acreage  prospective for coalbed methane
development in the Powder River Basin of Wyoming from Gastar  Exploration,  Ltd.
Pinnacle  also  agreed  to fund up to  $14.9  million  of  future  drilling  and
development  costs on these properties on behalf of Gastar prior to December 31,
2005.  The  drilling  and  development  work will be done  under the terms of an
earn-in joint venture  agreement  between  Pinnacle and Gastar.  The majority of
these leases are part of, or adjacent to, the Bobcat  project area.  All of CCBM
and RMG's  interests in the Bobcat  project  area,  the only  producing  coalbed
methane  property owned by CCBM prior to the  transaction,  were  contributed to
Pinnacle.

Prior to and in connection  with its  contribution  of assets to Pinnacle,  CCBM
paid RMG approximately $1.8 million in cash as part of its outstanding  purchase
obligation on the coalbed methane  property  interests CCBM previously  acquired
from RMG. As of June 30, 2003,  approximately  $1.1 million remaining balance of
CCBM's  obligation  to RMG is  scheduled to be paid in monthly  installments  of
approximately  $52,805  through  November 2004 and a balloon payment on December
31, 2004. As of June 30, 2004,  the  remaining  balance on this  obligation  was
approximately  $0.3 million.  The RMG note is secured solely by CCBM's interests
in the  remaining  oil and  natural  gas  leases  in  Wyoming  and  Montana.  In
connection  with the Company's  investment in Pinnacle,  the Company  received a
reduction in the principal amount of the RMG note of approximately  $1.5 million
and relinquished the right to receive certain revenues related to the properties
contributed to Pinnacle.

CCBM continues its coalbed methane  business  activities and, in addition to its
interest  in  Pinnacle,  owns  direct  interests  in acreage in coalbed  methane
properties  in the Castle  Rock  project  area in Montana  and the Oyster  Ridge
project area in Wyoming,  which were not  contributed to Pinnacle.  CCBM and RMG
will  continue  to  conduct  exploration  and  development  activities  on these
properties as well as pursue other potential acquisitions. Other than indirectly
through  Pinnacle,  CCBM  currently has no proved  reserves of, and is no longer
receiving revenue from, coalbed methane gas.

As of December 31, 2003,  on a fully  diluted  basis,  assuming that all parties
exercised their Pinnacle Warrants and Pinnacle Stock Options,  the CSFB Parties,
CCBM and RMG would have ownership  interests of approximately  46.2%,  26.9% and
26.9%,  respectively.  In March 2004,  the CSFB Parties  contributed  additional
funds of $11.8  million into Pinnacle to continue  funding the 2004  development
program which increased the CSFB Parties'  ownership to 66.7% on a fully diluted
basis  assuming  CCBM and RMG each elect not to exercise  their  Pinnacle  Stock
Options.  Assuming that CCBM and RMG exercise their Pinnacle Stock Options,


                                       9


the CSFB parties' ownership interest in Pinnacle would be 54.6% and CCBM and RMG
each would own 22.7% on a fully diluted basis.

For accounting purposes,  the transaction was treated as a reclassification of a
portion  of CCBM's  investments  in the  contributed  properties.  The  property
contribution  made  by  CCBM  to  Pinnacle  was  intended  to  be  treated  as a
tax-deferred  exchange as constituted by property transfers under section 351(a)
of the Internal Revenue Code of 1986, as amended.

The reclassification of investments in contributed properties resulting from the
transaction  with Pinnacle are reflected in accordance with the full cost method
of accounting  in the  Company's  balance sheet as of December 31, 2003 and June
30, 2004.

6. INCOME TAXES:

The  Company  provided  deferred  income  taxes at the rate of 35%,  which  also
approximates  its statutory rate, that amounted to $1.1 million and $1.3 million
for the three months ended June 30, 2003 and 2004, respectively and $2.7 million
and $2.7 million for the six months ended June 30, 2003 and 2004, respectively.

7. COMMITMENTS AND CONTINGENCIES:

From time to time,  the  Company is party to certain  legal  actions  and claims
arising in the ordinary  course of  business.  While the outcome of these events
cannot be predicted with certainty,  management does not expect these matters to
have a materially adverse effect on the financial position of the Company.

The  operations  and financial  position of the Company  continue to be affected
from  time to  time  in  varying  degrees  by  domestic  and  foreign  political
developments as well as legislation  and regulations  pertaining to restrictions
on oil and natural gas production,  imports and exports, natural gas regulation,
tax increases,  environmental  regulations and  cancellation of contract rights.
Both the likelihood  and overall effect of such  occurrences on the Company vary
greatly and are not predictable.

8. CONVERTIBLE PARTICIPATING PREFERRED STOCK:

In  February  2002,  the  Company  consummated  the  sale of  60,000  shares  of
Convertible  Participating  Series B  Preferred  Stock (the  "Series B Preferred
Stock") and warrants to purchase 252,632 shares of common stock for an aggregate
purchase  price of $6.0  million.  The Company sold 40,000 and 20,000  shares of
Series B Preferred  Stock and 168,422  and 84,210  warrants to Mellon  Ventures,
Inc.  and Steven A.  Webster,  respectively.  The Series B  Preferred  Stock was
convertible  into common stock by the  investors at a conversion  price of $5.70
per share, subject to adjustments,  and was initially convertible into 1,052,632
shares of common stock.  Dividends on the Series B Preferred  Stock were payable
in either cash at a rate of 8% per annum or, at the Company's option, by payment
in kind of additional  shares of the same series of preferred stock at a rate of
10% per annum.  At December 31, 2003 and through the conversion  dates specified
below,  the  outstanding  balance  of the  Series  B  Preferred  Stock  has been
increased by $1.2 million  (11,987  shares) and $1.5  million  (15,133  shares),
respectively,  for  dividends  paid in kind.  The Series B  Preferred  Stock was
redeemable  at varying  prices in whole or in part at the holders'  option after
three years or at the Company's option at any time. The Series B Preferred Stock
also participated in any dividends declared on the common stock.  Holders of the
Series B Preferred  Stock would have received a liquidation  preference upon the
liquidation  of,  or  certain  mergers  or sales  of  substantially  all  assets
involving,  the Company.  Such holders also had the option of receiving a change
of control  repayment price upon certain deemed change of control  transactions.
Mellon  Ventures,   Inc.,   converted  all  of  its  Series  B  Preferred  Stock
(approximately  49,938  shares) into  876,099  shares of common stock on May 25,
2004.  Steven  A.  Webster  converted  all  of  his  Series  B  Preferred  Stock
(approximately  25,195  shares) into 442,025  shares of common stock on June 30,
2004. As a result, no shares of Series B Preferred Stock remain outstanding. The
warrants have a five-year term and entitle the holders to purchase up to 252,632
shares of  Carrizo's  common  stock at a price of $5.94 per  share,  subject  to
adjustments, and are exercisable at any time after issuance. The warrants may be
exercised  on a cashless  exercise  basis.  During the six months ended June 30,
2004, Mellon Ventures,  Inc. exercised all of its 168,422 warrants on a cashless
exercise basis for a total of 36,570 shares of common stock.

Net proceeds of this  financing  were  approximately  $5.8 million and were used
primarily to fund the Company's ongoing  exploration and development program and
general corporate purposes.

9. SHAREHOLDER'S EQUITY:

In the first  quarter of 2004,  the  Company  completed  the public  offering of
6,485,000  shares of common  stock at $7.00 per  share.  The  offering  included
3,655,500  newly  issued  shares  offered by the  Company and  2,829,500  shares
offered by certain  existing


                                       10


stockholders.  The Company did not receive any proceeds  from the shares sold by
the selling stockholders.  The Company expects to use the net proceeds from this
offering to accelerate  its drilling  program and to retain larger  interests in
portions of its drilling prospects that the Company otherwise would sell down or
for which the  Company  would  seek joint  partners  and for  general  corporate
purposes.  In the  meantime,  the Company  used a portion of the net proceeds to
repay the $7 million  outstanding  principal  amount under our revolving  credit
facility and to complete a $8.2 million  Barnett Shale  acquisition  on February
27, 2004.

The Company  issued 55,334 and  7,305,949  shares of common stock during the six
months ended June 30, 2003 and 2004, respectively.  The shares issued during the
six  months  ended  June 30,  2003 were the  result of the  exercise  of options
granted under the  Company's  Incentive  Plan.  The shares issued during the six
months ended June 30, 2004,  consisted of 3,655,500  shares  issued  through the
secondary  offering,  2,159,627  shares issued through the exercise of warrants,
1,318,124  shares issued through the conversion of Series B Preferred  Stock and
the balance issued  through the exercise of options  granted under the Company's
Incentive Plan.

In June of 1997,  the Company  established  the Incentive  Plan of Carrizo Oil &
Gas, Inc. (the "Incentive Plan"). In October 1995, the FASB issued SFAS No. 123,
"Accounting for Stock-Based  Compensation," which requires the Company to record
stock-based  compensation  at fair value. In December 2002, the FASB issued SFAS
No. 148,  "Accounting for Stock Based Compensation - Transition and Disclosure."
The  Company has adopted  the  disclosure  requirements  of SFAS No. 148 and has
elected to record employee  compensation  expense  utilizing the intrinsic value
method  permitted  under  Accounting  Principles  Board  (APB)  Opinion  No. 25,
"Accounting  for Stock  Issued  to  Employees."  The  Company  accounts  for its
employees'  stock-based  compensation  plan  under  APB  Opinion  No. 25 and its
related interpretations. Accordingly, any deferred compensation expense would be
recorded for stock options based on the excess of the market value of the common
stock on the date the options were granted over the aggregate  exercise price of
the options.  This  deferred  compensation  would be amortized  over the vesting
period of each option.  Had  compensation  cost been determined  consistent with
SFAS No. 123  "Accounting  for Stock Based  Compensation"  for all options,  the
Company's net income (loss) and earnings per share would have been as follows:

10. CHANGE IN ACCOUNTING PRINCIPLE:

In June 2001,  the  Financial  Accounting  Standards  Board issued SFAS No. 143,
"Accounting for Asset Retirement  Obligations."  This Statement is effective for
fiscal  years  beginning  after  June 15,  2002,  and the  Company  adopted  the
Statement  effective  January 1, 2003.  During the three  months ended March 31,
2003, the Company recorded a cumulative effect of change in accounting principle
of $0.1  million,  $0.4  million  as proved  properties  and $0.5  million  as a
liability for its plugging and abandonment expenses.

11. DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITY:

The Company's  operations  involve  managing  market risks related to changes in
commodity prices. Derivative financial instruments, specifically swaps, futures,
options and other  contracts,  are used to reduce and manage  those  risks.  The
Company addresses market risk by selecting  instruments whose value fluctuations
correlate  strongly with the  underlying  commodity  being  hedged.  The Company
enters into swaps, options,  collars and other derivative contracts to hedge the
price risks associated with a portion of anticipated  future oil and natural gas
production.  While the use of hedging  arrangements  limits the downside risk of
adverse  price  movements,  it  may  also  limit  future  gains  from  favorable
movements.  Under these  agreements,  payments are received or made based on the
differential  between a fixed and a variable product price. These agreements are
settled in cash at expiration or exchanged for physical delivery contracts.  The
Company  enters  into  the  majority  of  its  hedging   transactions  with  two
counterparties  and a netting  agreement is in place with those  counterparties.
The Company does not obtain  collateral to support the  agreements  but monitors
the  financial  viability  of  counterparties  and  believes  its credit risk is
minimal on these transactions. In the event of nonperformance, the Company would
be exposed to price risk. The Company has some risk of accounting loss since the
price received for the product at the actual physical  delivery point may differ
from the  prevailing  price at the delivery point required for settlement of the
hedging transaction.

As of December 31, 2003 and June 30, 2004, $0.2 million and $0.5 million, net of
tax of $0.1  million and $0.3  million,  respectively,  remained in  accumulated
other  comprehensive  income  related to the valuation of the Company's  hedging
positions.

Total oil hedged under swaps and collars  during the three months ended June 30,
2003 and 2004 were 63,300 Bbls and 27,300 Bbls, respectively.  Total natural gas
hedged  under swaps and collars  during the three months ended June 30, 2003 and
2004 were 819,000  MMBtu and  1,001,000  MMBtu,  respectively.  Total oil hedged
under swaps and collars  during the six months ended June 30, 2003 and 2004 were
126,300 Bbls and 54,300 Bbls, respectively. Total natural gas hedged under swaps
and collars  during the six months  ended June 30, 2003 and 2004 were  1,349,000
MMBtu and 1,727,000 MMBtu, respectively.  The net losses realized by the Company
under such hedging  arrangements were $0.4 and $0.5 million for the three months
ended June 30, 2003 and 2004, respectively,  and are included in oil and natural
gas  revenues.  The net  losses  realized  by the  Company  under  such  hedging
arrangements  were $1.7  million and $0.4  million for six months ended June 30,
2003 and 2004, respectively, and are included in oil and natural gas revenues.

At June 30,  2003  and 2004 the  Company  had the  following  outstanding  hedge

                  ITEM 2 - MANAGEMENT'S DISCUSSION AND ANALYSIS
                OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS



The following is  management's  discussion  and analysis of certain  significant
factors that have affected certain aspects of the Company's  financial  position
and  results of  operations  during the  periods  included  in the  accompanying
unaudited  financial  statements.  You should read this in conjunction  with the
discussion under  "Management's  Discussion and Analysis of Financial  Condition
and Results of Operations" and the audited financial  statements included in our
Annual  Report  on Form  10-K  for the  year  ended  December  31,  2003 and the
unaudited financial statements included elsewhere herein.

General Overview

We began  operations in September 1993 and initially  focused on the acquisition
of producing properties.  As a result of the increasing availability of economic
onshore 3-D seismic  surveys,  we began obtaining 3-D seismic data and optioning
to lease substantial  acreage in 1995 and began drilling our 3-D based prospects
in 1996. In 2003, we drilled 39 gross wells (10.2 net), 35 gross wells (9.4 net)
of which  were  successful.  During  the six  months  ended  June 30,  2004,  we
participated  in the drilling of 40 gross wells (14.7 net) in the Gulf Coast and
North Texas regions,  36 gross wells (12.1 net) of which were successful.  33 of
these successful wells have been completed and three are in the process of being
completed. We have budgeted to drill up to 44 gross wells (15.3 net) in the Gulf
Coast  region in 2004;  however,  the actual  number of wells  drilled will vary
depending upon various factors,  including the availability and cost of drilling
rigs,  land and  industry  partner  issues,  our cash flow,  success of drilling
programs,  weather delays and other factors.  If we drill the number of wells we
have  budgeted  for 2004,  depreciation,  depletion  and  amortization,  oil and
natural gas  operating  expenses and  production  are expected to increase  over
levels incurred in 2003.

Since our initial public offering,  we have primarily grown through the internal
development of properties  within our  exploration  project  areas,  although we
consider  acquisitions  from  time  to  time  and  may  in the  future  complete
acquisitions that we find attractive.  In February 2004, we acquired assets in a
Barnett Shale play in North Texas for approximately $8.2 million.

2004 Public Offering

In the first  quarter of 2004,  we  completed  the public  offering of 6,485,000
shares of our common stock at $7.00 per share. The offering  included  3,655,500
newly  issued  shares  offered  by us and  2,829,500  shares  offered by certain
existing  stockholders.  We did not receive any proceeds from the shares offered
by the selling  stockholders.  We expect to use our  estimated  net  proceeds of
approximately  $23.4  million  from this  offering to  accelerate  our  drilling
program and to retain  larger  interests in portions of our  drilling  prospects
that we otherwise  would sell down or for which we would seek joint partners and
for general corporate  purposes.  In the meantime,  we used a portion of the net
proceeds  to  repay  the $7  million  outstanding  principal  amount  under  our
revolving  credit  facility  and to  purchase  the $8.2  million  Barnett  Shale
acquisition mentioned below.

Barnett Shale Activity

On February  27,  2004,  we closed an $8.2  million  transaction  with a private
company to acquire working  interests and acreage in certain oil and natural gas
wells  located in the Newark East Field in Denton  County,  Texas in the Barnett
Shale  trend.  This  acquisition  includes  non-operated  working  interests  in
properties  ranging  from 12.5% to 45% over  3,800  gross  acres,  or an average
working  interest of 39%.  The Barnett  Shale  acquisition  included 21 existing
gross wells (6.7 net) and interests in approximately  1,500 net acres,  which we
expect to provide  another 31 gross drill sites:  13 of which will target proved
undeveloped reserves and 18 of which will be exploratory. Current net production
from the acquired  properties in July 2004 was approximately 1.5 Mmcfe/d and net
proved reserves are internally estimated at 12.2 Bcfe.

Initially,  we financed the Barnett Shale acquisition with our available cash on
hand.  We are  exploring  a number of  financing  alternatives  to  refinance  a
majority of the  acquisition and to fund a majority of our 2004 and 2005 capital
expenditure  program  for the Barnett  Shale play.  We may not be able to obtain
such financing on terms that are acceptable to us, or at all.

In mid-2003,  we became  active in the Barnett Shale play located in Tarrant and
Parker counties in Northeast Texas. Our activity  accelerated as a result of the
acquisition described above.



                                       14


In the Barnett Shale play, we drilled six gross wells in 2003 and 19 gross wells
(7.9  net)  during  the six  months  ended  June 30,  2004,  all of  which  were
successful.  We plan to drill  between 30 and 45 gross  wells in this  region in
2004, assuming that we obtain the additional financing mentioned above.

Pinnacle Gas Resources, Inc.

During the second quarter of 2001, we acquired  interests in natural gas and oil
leases in Wyoming  and  Montana in areas  prospective  for  coalbed  methane and
subsequently began to drill wells on those leases.  During the second quarter of
2003, we contributed  our interests in certain of these leases to a newly formed
company,  Pinnacle  Gas  Resources,  Inc.  ("Pinnacle").  In  exchange  for this
contribution,  we received  37.5% of the common stock of Pinnacle and options to
purchase  additional  Pinnacle  common stock. In February 2004, the CSFB Parties
contributed  additional funds of $11.8 million into Pinnacle to continue funding
the 2004  development  program which will increase their ownership to 66.7% on a
fully  diluted  basis should we and RMG each elect not to exercise our available
options.

The business  operations and development program of Pinnacle does not require us
to provide any further  capital  infusion,  unless we  determine to exercise our
options.  We account for our interest in Pinnacle using the equity method.  As a
result, our contributed operations and reserves are no longer directly reflected
in our  financial  statements.  Our  discussion  of future  drilling and capital
expenditures does not reflect operations conducted through Pinnacle.

In  addition  to  our  interest  in  Pinnacle,   CCBM   retained   interests  in
approximately  145,000  gross acres in the Castle Rock coalbed  methane  project
area in Montana and the Oyster Ridge project area in Wyoming.

Hedging

Our financial  results are largely  dependent on a number of factors,  including
commodity  prices.  Commodity prices are outside of our control and historically
have been and are expected to remain volatile.  Natural gas prices in particular
have remained volatile during the last few years.  Commodity prices are affected
by changes in market  demands,  overall  economic  activity,  weather,  pipeline
capacity  constraints,  inventory storage levels,  basis differentials and other
factors.  As a result, we cannot accurately  predict future natural gas, natural
gas liquids and crude oil  prices,  and  therefore,  cannot  accurately  predict
revenues.

Because  natural gas and oil prices are  unstable,  we  periodically  enter into
price-risk-management  transactions such as swaps, collars,  futures and options
to reduce our exposure to price  fluctuations  associated  with a portion of our
natural gas and oil production and to achieve a more  predictable cash flow. The
use of these  arrangements  limits our ability to benefit from  increases in the
prices of natural  gas and oil.  Our  hedging  arrangements  may apply to only a
portion of our production and provide only partial  protection  against declines
in natural gas and oil prices.

Results of Operations

Three Months Ended June 30, 2004,
Compared to the Three Months Ended June 30, 2003

Oil and natural gas revenues for the three months ended June 30, 2004  increased
35% to $12.0  million from $8.8 million for the same period in 2003.  Production
volumes for natural gas during the three  months  ended June 30, 2004  increased
from  1.0 Bcf for the  three  months  ended  June 30,  2003 to 1.5 Bcf.  Average
natural gas prices  increased 8% to $6.07 per Mcf in the second  quarter of 2004
from $5.64 per Mcf in the same period in 2003. Production volumes for oil in the
second  quarter  of 2004  decreased  30% to 83 MBbls from 118 MBbls for the same
period in 2003.  Average  oil prices  increased  25% to $35.27 per barrel in the
second  quarter of 2004 from  $28.23 per  barrel in the same period in 2003. The
increase in natural gas production was due to the  commencement of production at
the Beach House #1 and #2,  Shadyside #1 and the Barnett  Shale wells  partially
offset by the natural  decline in production  at the Staubach #1,  Burkhart #1R,
Matthes  Heubner #1 and other  wells.  The  decrease in oil  production  was due
primarily to the natural decline of production at the Staubach #1, Burkhart #1R,
Pauline Huebner A-382 #1, Matthes Huebner #1 and other wells partially offset by
the  commencement  of  production  from the Beach House #1 and #2 and from other
wells. Oil and natural gas revenues include the impact of hedging  activities as
discussed above under "General Overview."

Oil and natural gas operating  expenses for the three months ended June 30, 2004
increased  16% to $2.0  million  from $1.8  million for the same period in 2003.
Operating  expenses per equivalent unit decreased  slightly to $1.03 per Mcfe in
the second  quarter  of 2004  compared  to $1.05 per Mcfe in the same  period in
2003.

Depreciation,  depletion and  amortization  (DD&A)  expense for the three months
ended June 30, 2004  increased  38% to $3.6  million  ($1.81 per Mcfe) from $2.6
million ($1.55 per Mcfe) for the same period in 2003.  DD&A increased  primarily
due to increased  production and expenses  resulting from additional seismic and
drilling costs.

General  and  administrative  expense for the three  months  ended June 30, 2004
increased  by $0.3 million to $1.6 million from $1.3 million for the same period
in 2003 primarily as a result of higher  directors' fees ($0.1 million),  higher
legal fees ($0.1 million) in connection with a subordinated debt refinancing and
higher  professional   expenses  related  to  Sarbanes-Oxley   Compliance  ($0.1
million).

Stock option  compensation  expense was $0.7 million for the quarter  ended June
30, 2004.

We recorded a $0.4 million after tax charge,  or $0.02 per fully diluted share,
on our  minority  interest in Pinnacle for the three months ended June 30, 2004.
It is likely that Pinnacle will continue to record a valuation  allowance on the
deferred federal tax benefit generated from the operating losses incurred during
at least the early development stages of Pinnacle's coalbed methane projects. We
have not recorded a deferred  federal  income tax benefit  generated  from these
operating losses due to the uncertainty of future Pinnacle income.

Income taxes  increased to $1.4 million for the three months ended June 30, 2004
from $1.1  million  for the same  period  in 2003 as a result of higher  taxable
income based on the factors described above.

Capitalized interest was unchanged at $0.7 million in the second quarter of 2004
from $0.7 million for the second quarter of 2003.

Six Months Ended June 30, 2004,
Compared to the Six Months Ended June 30, 2003

Oil and natural gas revenues  for the six months  ended June 30, 2004  increased
17% to $22.8 million from $19.5 million for the same period in 2003.  Production
volumes for natural gas during the six months ended June 30, 2004  increased 36%
to 2.8 Bcf from 2.1 Bcf for the same period in 2003.  Average natural gas prices
increased 4% to $6.00 per Mcf in the first six months of 2004 from $5.78 per Mcf
in the same period in 2003.  Production  volumes for oil in the first six months
of 2004  decreased  34% to 171 MBbls from 258 MBbls for the same period in 2003.
Average oil prices increased 18% to $34.41 per barrel in the first six months of
2004 from $29.04 per barrel in the same period in 2003.  The increase in natural
gas production was primarily due to the  commencement of production at the Beach
House #1 and #2, Shadyside #1 and the Barnett Shale wells, offset by the natural
decline in production at the Staubach #1,  Burkhart #1R,  Pauline  Huebner A-382
#1,  Matthes  Huebner #1,  Delta Farms #1 and other  wells.  The decrease in oil
production was


                                       16


due primarily to the natural  decline of production at the Staubach #1, Burkhart
#1R,  Pauline  Huebner  A-382 #1,  Matthes  Huebner #1 and Delta Farms #1 wells,
offset by the commencement of production from the Beach House #1 and #2 and from
other  wells.  Oil and  natural  gas  revenues  include  the  impact of  hedging
activities as discussed above under "General Overview".

The following  table  summarizes  production  volumes,  average sales prices and

Oil and natural gas  operating  expenses  for the six months ended June 30, 2004
increased  to $3.7  million  from  $3.5  million  for the same  period  in 2003.
Operating  expenses per equivalent  unit were  virtually  unchanged at $0.97 per
Mcfe in the first  six  months  of 2004  compared  to $0.96 per Mcfe in the same
period in 2003.

Depreciation, depletion and amortization (DD&A) expense for the six months ended
June 30, 2004  increased 21% to $6.9 million  ($1.78 per Mcfe) from $5.6 million
($1.56 per Mcfe) for the same period in 2003.  DD&A  increased  primarily due to
increased production and expenses resulting from additional seismic and drilling
costs.

General  and  administrative  expense  for the six months  ended  June 30,  2004
increased  by $1.1 million to $3.8 million from $2.7 million for the same period
in 2003  primarily  as a result of higher  incentive  compensation  costs  ($0.4
million),  higher  directors'  fees  ($0.1  million),  higher  legal  fees ($0.1
million)  in  connection  with  the  subordinated   debt   refinancing,   higher
professional  expenses related to  Sarbanes-Oxley  compliance ($0.1 million) and
higher professional expenses in connection with the 2003 audit ($0.3 million).

Stock option compensation expense was $0.8 million for the six months ended June
30, 2004.

We recorded a $0.6 million after tax charge,  or $0.03 per fully diluted  share,
on our minority  interest in Pinnacle for the six months ended June 30, 2004. It
is likely that  Pinnacle  will  continue to record a valuation  allowance on the
deferred federal tax benefit generated from the operating losses incurred during
at least the early development stages of Pinnacle's coalbed methane projects. We
have not recorded a deferred  federal  income tax benefit  generated  from these
operating losses due to the uncertainty of future Pinnacle income.

Income  taxes  decreased  to $2.7 million for the six months ended June 30, 2004
from $2.8  million  for the same  period  in 2003 as a result  of lower  taxable
income based on the factors described above.

Capitalized  interest  decreased to $1.3 million in the first six months of 2004
from $1.5 million for the first six months of 2003 as a result of lower interest
due to the  repayment  of a portion of the Rocky  Mountain Gas note and the then
outstanding balance under the Hibernia facility.

                                       17


We  adopted  Financial  Accounting  Standards  Board's  Statement  of  Financial
Standards  No.  143  "Accounting  for Asset  Retirement  Obligations"  effective
January  1,  2003,  and  recorded a  cumulative  effect of change in  accounting
principle of $0.1 million in the six months ended June 30, 2003.

Liquidity and Capital Resources

During the six months  ended June 30,  2004,  we made  capital  expenditures  in
excess of our net cash flows provided by operating activities, using in part the
proceeds generated from our equity offering.  For future capital expenditures in
2004,  we expect to continue to use such proceeds and cash on hand as well as to
draw  on  the  Hibernia   facility  to  partially  fund  our  planned   drilling
expenditures  and fund leasehold costs and geological and  geophysical  costs on
our  exploration  projects  in 2004.  We also  continue  to  consider  financing
alternatives  to fund our Barnett Shale capital  program.  While we believe that
current cash balances,  availability under the Hibernia Facility and anticipated
2004 cash provided by operating  activities will provide  sufficient  capital to
carry out our 2004 exploration  plans,  there can be no assurance that this will
be the case.

We may  not be able  to  obtain  adequate  financing  on  terms  that  would  be
acceptable to us. If we cannot obtain adequate financing,  we anticipate that we
may be required to limit or defer our  planned  natural gas and oil  exploration
and development  program,  thereby adversely  affecting the  recoverability  and
ultimate value of our natural gas and oil properties.

Our liquidity  position has been enhanced by our receipt of approximately  $23.4
million in net  proceeds  from the  completion  of our 2004  public  offering as
described  above.  Our other primary  sources of liquidity  have included  funds
generated  by  operations,  proceeds  from the  issuance of various  securities,
including  our common  stock,  preferred  stock and  warrants,  and  borrowings,
primarily under revolving  credit  facilities and through the issuance of senior
subordinated notes.

Cash flows provided by operating activities were $15.1 million and $17.3 million
for the six months ended June 30, 2003 and 2004,  respectively.  The increase in
cash flows provided by operating  activities in 2004 as compared to 2003 was due
primarily  to changes  in working  capital  in 2004,  primarily  higher  accrued
expenses.

We have budgeted capital expenditures in 2004 of approximately $51.3 million, of
which  $39.8  million is  expected  to be used for  drilling  activities  in our
project  areas  and the  balance  is  expected  to be used to fund  3-D  seismic
surveys,  land acquisitions and capitalized  interest and overhead costs.  These
capital  expenditure  amounts do not include the approximately  $8.2 million for
the Barnett Shale acquisition.  We have budgeted to drill approximately 44 gross
wells  (15.3 net) in the Gulf  Coast  region in 2004.  The  budget for  drilling
additional  gross and net wells in the Barnett  Shale trend in 2004 is dependent
upon  the  timing  and  amount  of  additional  funding.  We  intend  to  obtain
alternative  financing to fund a majority of our  acquisition,  exploration  and
development  program in the Barnett Shale trend in 2004. If we are successful in
obtaining this facility,  we expect our capital  expenditures in the trend could
increase between $15 and $20 million in 2004. The actual number of wells drilled
and  capital  expended  is  dependent  upon  available  financing,   cash  flow,
availability  and cost of  drilling  rigs,  land and  partner  issues  and other
factors.

We have  continued  to  reinvest  a  substantial  portion of our cash flows into
increasing our 3-D prospect portfolio,  improving our 3-D seismic interpretation
technology  and  funding  our  drilling  program.  Oil and  natural  gas capital
expenditures  were $14.1 million and $39.1 million  (including  our $8.2 million
Barnett  Shale  acquisition)  for the six months  ended June 30,  2003 and 2004,
respectively.  Our drilling efforts resulted in the successful  completion of 35
gross  wells  (9.4 net) in 2003 and 17 gross  wells  (4.2 net) in the Gulf Coast
region and 11 gross wells (3.9 net) in the Barnett  Shale play in the six months
ended June 30, 2004. We have  completed 33 of these wells and are in the process
of completing three of these wells as of June 30, 2004.

Since  inception,  Pinnacle has reported that it drilled 210 gross wells through
June 30, 2004 and  estimates  that 80% of them were  completed by June 30, 2004.
Pinnacle  reportedly added approximately 11.4 Bcf of net proved reserves through
development  drilling  through May 31, 2004. Its gross  operated  production has
increased by  approximately  117% since its  inception  (to  approximately  10.4
MMcf/d at June 30, 2004),  and its total well count stands at 449 gross operated
wells.

CCBM has  spent  $4.6  million  for  drilling  costs,  of 50% of which was spent
pursuant to an  obligation  to fund $2.5 million of drilling  costs on behalf of
RMG.  As of June 30,  2004,  CCBM had  satisfied  $2.3  million of its  drilling
obligations on behalf of RMG.

Financing Arrangements

Hibernia Credit Facility

On May 24, 2002, we entered into a credit agreement with Hibernia  National Bank
(the  "Hibernia  Facility")  which  matures on January 31, 2006,  and repaid our
existing  facility  with Compass  Bank (the  "Compass  Facility").  The Hibernia
Facility  provides  a  revolving  line of credit of up to $30.0  million.  It is
secured by substantially all of our assets and is guaranteed by our subsidiary.

The  borrowing  base  will be  determined  by  Hibernia  National  Bank at least
semi-annually  on each  October  31 and  April  30.  Each  party  to the  credit
agreement can request one unscheduled borrowing base determination subsequent to
each  scheduled  determination.  The borrowing  base will at all times equal the
borrowing  base  most  recently  determined  by  Hibernia  National  Bank,  less
quarterly  borrowing base reductions  required subsequent to such determination.
Hibernia  National Bank will reset the borrowing  base amount at each  scheduled
and each unscheduled borrowing base determination date.

The terms of our existing and future  financial  instruments may affect the size
of our borrowing base. See "--Senior Subordinated Notes and Related Securities."
On December 12, 2002, we entered into an Amended and Restated  Credit  Agreement
with  Hibernia  National Bank that provided  additional  availability  under the
Hibernia  Facility  in the  amount of $2.5  million  which is  structured  as an
additional  "Facility  B"  under  the  Hibernia  Facility.  As such,  the  total
borrowing base under the Hibernia  Facility as of December 31, 2003 and June 30,
2004 was $19.0 million and $26.0 million,  respectively,  of which $7.0 and $9.0
million, respectively, were drawn as of such dates. The Facility B bore interest
at LIBOR plus 3.375%, was secured by certain leases and working interests in oil
and natural gas wells and matured on April 30, 2003.  We used  proceeds from our
offering  in  February  2004 to repay  the then  outstanding  balance  under the
Hibernia Facility.

If the  principal  balance of the Hibernia  Facility  ever exceeds the borrowing
base as reduced by the quarterly  borrowing base reduction (as described above),
the principal balance in excess of such reduced borrowing base will be due as of
the date of such reduction.  Otherwise, any unpaid principal or interest will be
due at maturity.

If the  outstanding  principal  balance of the  Hibernia  Facility  exceeds  the
borrowing base at any time, we have the option within 30 days to take any of the
following  actions,  either  individually  or in  combination:  make a lump  sum
payment  curing the  deficiency,  pledge  additional  collateral  sufficient  in
Hibernia  National  Bank's  opinion to increase the borrowing  base and cure the
deficiency or begin making equal monthly  principal  payments that will cure the
deficiency  within the ensuing  six-month  period.  Those  payments  would be in
addition  to any  payments  that  may  come  due as a  result  of the  quarterly
borrowing base reductions.  Otherwise,  any unpaid principal or interest will be
due at maturity.

For each tranche of principal  borrowed under the revolving line of credit,  the
interest  rate  will  be,  at our  option:  (i)  the  Eurodollar  Rate,  plus an
applicable  margin  equal to 2.375% if the amount  borrowed  is greater  than or
equal to 90% of the  borrowing  base,  2.0% if the amount  borrowed is less than
90%, but greater than or equal to 50% of the  borrowing  base,  or 1.625% if the
amount  borrowed is less than 50% of the borrowing  base; or (ii) the Base Rate,
plus an  applicable  margin of 0.375% if the amount  borrowed is greater than or
equal to 90% of the borrowing base.  Interest on Eurodollar  Loans is payable on
either the last day of each  Eurodollar  option period or monthly,  whichever is
earlier. Interest on Base Rate Loans is payable monthly.

We are subject to certain  covenants  under the terms of the Hibernia  Facility,
including,  but  not  limited  to the  maintenance  of the  following  financial
covenants:  (i) a minimum  current ratio of 1.0 to 1.0  (including  availability
under the borrowing base),  (ii) a minimum  quarterly debt services  coverage of
1.25 times, and (iii) a minimum shareholders equity equal to $56.0 million, plus
100% of all subsequent common and preferred equity  contributed by shareholders,
plus 50% of all positive earning  occurring  subsequent to such quarter end, all
ratios as more  particularly  discussed  in the credit  facility.  The  Hibernia
Facility  also places  restrictions  on  additional  indebtedness,  dividends to
non-preferred stockholders,  liens, investments,  mergers,  acquisitions,  asset
dispositions,  asset  pledges and  mortgages,  change of control,  repurchase or
redemption  for cash of our common or  preferred  stock,  speculative  commodity
transactions, and other matters.

Rocky Mountain Gas Note

In June 2001,  CCBM issued a non-recourse  promissory note payable in the amount
of $7.5 million to RMG as consideration for certain interests in oil and natural
gas  leases  held by RMG in  Wyoming  and  Montana.  The RMG note is  payable in
41-monthly  principal  payments of $0.1  million  plus  interest at 8% per annum
commencing July 31, 2001 with the balance due December 31, 2004. The RMG note is
secured solely by CCBM's  interests in the oil and natural gas leases in Wyoming
and Montana.  At December 31, 2003 and June 30, 2004, the outstanding  principal
balance  of this  note  was $0.9  million  and $0.3  million,  respectively.  In
connection

                                       19


with our investment in Pinnacle, we received a reduction in the principal amount
of the RMG note of  approximately  $1.5  million and  relinquished  the right to
certain revenues related to the properties  contributed to Pinnacle.  During the
second quarter of 2004, CCBM  relinquished a portion of its interests in certain
oil and natural gas leases and  reduced  the  principal  due on the note by $0.3
million.

Capital Leases

In December 2001, we entered into a capital lease  agreement  secured by certain
production  equipment in the amount of $0.2 million. The lease is payable in one
payment of $11,323 and 35 monthly payments of $7,549 including  interest at 8.6%
per annum. In October 2002, we entered into a capital lease agreement secured by
certain production equipment in the amount of $0.1 million. The lease is payable
in 36 monthly  payments of $3,462  including  interest at 6.4% per annum. In May
2003, we entered into a capital lease  agreement  secured by certain  production
equipment  in the  amount of $0.1  million.  The lease is  payable in 36 monthly
payments of $3,030  including  interest at 5.5% per annum.  In August  2003,  we
entered into a capital lease agreement secured by certain  production  equipment
in the amount of $0.1  million.  The lease is payable in 36 monthly  payments of
$2,179  including  interest at 6.0% per annum. We have the option to acquire the
equipment at the conclusion of the lease for $1 under all of these leases.  DD&A
on the capital leases for the three months ended June 30, 2003 and 2004 amounted
to $11,000 and  $12,000,  respectively.  DD&A on the capital  leases for the six
months  ended  June  30,  2003  and  2004   amounted  to  $20,000  and  $24,000,
respectively,  and accumulated DD&A on the leased equipment at December 31, 2003
and June 30, 2004 amounted to $76,000 and $100,000, respectively.

Senior Subordinated Notes and Related Securities

In December 1999, we consummated the sale of $22.0 million  principal  amount of
9%  Senior  Subordinated  Notes  due 2007 (the  "Subordinated  Notes")  and $8.0
million of common stock and Warrants.  We sold $17.6 million, $2.2 million, $0.8
million,  $0.8 million and $0.8 million principal amount of Subordinated  Notes;
2,909,092,  363,636, 121,212, 121,212 and 121,212 shares of our common stock and
2,208,152,  276,019, 92,006, 92,006 and 92,006 Warrants to CB Capital Investors,
L.P. (now known as J.P.  Morgan  Partners (23A SBIC),  L.P.),  Mellon  Ventures,
L.P.,  Paul  B.  Loyd,  Jr.,  Steven  A.  Webster  and  Douglas  A.P.  Hamilton,
respectively.  The  Subordinated  Notes were sold at a discount of $0.7 million,
which is being amortized over the life of the notes.  Interest  payments are due
quarterly  commencing on March 31, 2000. We may, until December 2004, elect, and
historically have elected,  to increase the amount of the Subordinated Notes for
60% of the interest which would  otherwise be payable in cash. As a result,  our
cash  obligation on the  Subordinated  Notes will increase  significantly  after
December 2004. This increase is likely to reduce the amount  available to us for
borrowing  under the  Hibernia  Facility.  As of December  31, 2003 and June 30,
2004, the outstanding  balance of the  Subordinated  Notes had been increased by
$5.3 million and $6.0  million,  respectively,  for such  interest paid in kind.
Concurrently  with  the  sale of the  Subordinated  Notes,  we sold to the  same
purchasers  3,636,364  shares of our common  stock at a price of $2.20 per share
and warrants expiring in December 2007 to purchase up to 2,760,189 shares of our
common stock at an exercise price of $2.20 per share.  For accounting  purposes,
the  warrants  were valued at $0.25 each.  During the six months  ended June 30,
2004, Mellon Ventures, L.P., JPMorgan Partners (23A SBIC), Steven A. Webster and
Douglas A. P. Hamilton exercised warrants to purchase 276,019, 2,208,152, 92,006
and 92,006 shares of common stock,  respectively,  on a cashless  exercise basis
for a total of 205,692,  1,684,949,  70,205 and 70,205  shares of common  stock,
respectively,  and Paul B. Loyd,  Jr.,  exercised  warrants to  purchase  92,006
shares for a total of 92,006 shares of common stock. As a result, no warrants to
purchase  shares  remain  outstanding  from the  warrants  originally  issued in
December 1999.

On June 7, 2004, an unaffiliated third party (the "Purchaser") purchased all the
outstanding Subordinated Notes from the original note holders. In exchange for a
$0.4 million  amendment fee,  certain terms and  conditions of the  Subordinated
Notes were amended, to provide for, among other things, (1) a one year extension
of the maturity to December 15, 2008, (2) a one year extension, through December

Series B Preferred Stock

In February 2002, we consummated the sale of 60,000 shares of Series B Preferred
Stock and 2002  Warrants  to  purchase  252,632  shares  of common  stock for an
aggregate purchase price of $6.0 million.  We sold $4.0 million and $2.0 million
of Series B Preferred Stock and 168,422 and 84,210 warrants to Mellon  Ventures,
Inc.  and  Steven A.  Webster,  respectively.  The Series B  Preferred  Stock is
convertible  into common stock by the  investors at a conversion  price of $5.70
per share,  subject to adjustment for transactions  including issuance of common
stock or securities  convertible  into or  exercisable  for common stock at less
than the conversion price, and is initially convertible into 1,052,632 shares of
common stock. The approximately $5.8 million net proceeds of this financing were
used to fund  our  ongoing  exploration  and  development  program  and  general
corporate purposes.  In the first quarter of 2004, Mellon Ventures exercised all
168,422 of its 2002  warrants on a cashless  basis and  received  36,570  shares
which it sold in the 2004 public offering.

Dividends on the Series B Preferred  Stock were payable in either cash at a rate
of 8% per annum or, at our option,  by payment in kind of  additional  shares of
the Series B Preferred  Stock at a rate of 10% per annum.  At December  31, 2003
and  through  the  conversion  dates,  the  outstanding  balance of the Series B
Preferred  Stock had been  increased  by $1.2 million  (11,987  shares) and $1.5
million (15,133 shares),  respectively,  for dividends paid in kind. In addition
to the  foregoing,  if we had declared a cash dividend on our common stock,  the
holders of shares of Series B Preferred  Stock were entitled to receive for each
share of Series B  Preferred  Stock a cash  dividend  in the  amount of the cash
dividend  that would  have been  received  by a holder of the common  stock into
which such share of Series B Preferred  Stock was convertible on the record date
for such cash dividend.  Unless all accrued  dividends on the Series B Preferred
Stock were paid and a sum  sufficient  for the  payment  thereof  set apart,  no
distributions  may be paid on any Junior Stock (which includes the common stock)
(as defined in the Statement of  Resolutions  for the Series B Preferred  Stock)
and no  redemption of any Junior Stock shall occur other than subject to certain
exceptions.

We must  redeem  the  Series  B  Preferred  Stock at any time  after  the  third
anniversary of our initial  issuance upon request from any holder at a price per
share equal to Purchase  Price/Dividend  Preference (as defined  below).  On the
other hand,  we may opt to redeem the Series B  Preferred  Stock after the third
anniversary  of its  issuance  at a  price  per  share  equal  to  the  Purchase
Price/Dividend Preference and, prior to that time, at varying preferences to the
Purchase  Price/Dividend  Preference.  "Purchase  Price/Dividend  Preference" is
defined to mean, generally, $100 plus all cumulative and accrued dividends.

In the event of any dissolution,  liquidation or winding up or specified mergers
or sales or other  disposition by us of all or substantially  all of our assets,
the holder of each share of Series B Preferred  Stock then  outstanding  will be
entitled to be paid per share of Series B Preferred Stock,  prior to the payment
to holders of our common stock and out of our assets  available for distribution
to our shareholders, the greater of:

     o    $100 in cash plus all cumulative and accrued dividends; and

     o    in   specified   circumstances,    the   "as-converted"    liquidation
          distribution, if any, payable in such liquidation with respect to each
          share of common stock.

Upon the  occurrence of certain  events  constituting  a "Change of Control" (as
defined in the  Statement of  Resolutions),  we are required to make an offer to
each  holder of Series B  Preferred  Stock to  repurchase  all of such  holder's
Series B Preferred Stock at an offer price per share of Series B Preferred Stock
in cash  equal  to 105% of the  Change  of  Control  Purchase  Price,  which  is
generally defined to mean $100 plus all cumulative and accrued dividends.

Mellon  Ventures,   Inc.,   converted  all  of  its  Series  B  Preferred  Stock
(approximately  49,938  shares) into  876,099  shares of common stock on May 25,
2004.  Steven  A.  Webster  converted  all  of  his  Series  B  Preferred  Stock
(approximately  25,195  shares) into 442,025  shares of common stock on June 30,
2004. As a result, no shares of Series B Preferred Stock remain outstanding.

The 2002 Warrants have a five-year term and  originally  entitled the holders to
purchase up to 252,632 shares of our common stock at a price of $5.94 per share,
subject to adjustment,  and are  exercisable at any time after  issuance.  As of
June 30, 2004, 84,210 of the 2002 Warrants remained outstanding.  For accounting
purposes,  the 2002 Warrants are valued at $0.06 per 2002  Warrant.

Each of our series of  warrants  may be  exercised  on a  cashless  basis at the
option of the holder.

Effects of Inflation and Changes in Price

Our  results of  operations  and cash flows are  affected  by  changing  oil and
natural gas prices.  If the price of oil and natural gas increases  (decreases),
there could be a corresponding increase (decrease) in the operating cost that we
are  required  to bear for  operations,  as well as an  increase  (decrease)  in
revenues. Inflation has had a minimal effect on us.

Critical Accounting Policies

The following summarizes several of our critical accounting policies:

Use of Estimates

The preparation of financial  statements in conformity  with generally  accepted
accounting principles requires management to make estimates and assumptions that
affect  the  reported  amounts  of assets  and  liabilities  and  disclosure  of
contingent  assets and  liabilities at the date of the financial  statements and
the  reported  amounts of revenues and expenses  during the  reporting  periods.
Actual  results could differ from these  estimates.  The use of these  estimates
significantly  affects natural gas and oil properties  through depletion and the
full cost ceiling test, as discussed in more detail below.

Oil and Natural Gas Properties

We account for investments in natural gas and oil properties using the full-cost
method  of  accounting.  All costs  directly  associated  with the  acquisition,
exploration and  development of natural gas and oil properties are  capitalized.
These costs  include  lease  acquisitions,  seismic  surveys,  and  drilling and
completion equipment. We proportionally consolidate our interests in natural gas
and oil  properties.  We capitalized  compensation  costs for employees  working
directly on exploration  activities of $0.7 million and $0.9 million for the six
months ended June 30, 2003 and 2004,  respectively.  We expense  maintenance and
repairs as they are incurred.

We  amortize  natural  gas and oil  properties  based on the  unit-of-production
method  using  estimates  of  proved  reserve  quantities.  We do  not  amortize
investments in unproved  properties  until proved  reserves  associated with the
projects  can  be  determined  or  until  these  investments  are  impaired.  We
periodically evaluate, on a property-by-property  basis,  unevaluated properties
for impairment. If the results of an assessment indicate that the properties are
impaired,  we add the amount of  impairment  to the proved  natural  gas and oil
property costs to be amortized.  The amortizable base includes  estimated future
development  costs  and,  where  significant,  dismantlement,   restoration  and
abandonment  costs, net of estimated salvage values. The depletion rate per Mcfe
for the  six  months  ended  June  30,  2003  and  2004  was  $1.50  and  $1.80,
respectively.

We account for  dispositions of natural gas and oil properties as adjustments to
capitalized costs with no gain or loss recognized, unless such adjustments would
significantly  alter the  relationship  between  capitalized  costs  and  proved
reserves.  We have  not had  any  transactions  that  significantly  alter  that
relationship.

The net  capitalized  costs of proved oil and natural gas properties are subject
to a "ceiling  test" which  limits such costs to the  estimated  present  value,
discounted at a 10% interest rate, of future net revenues from proved  reserves,
based on current  economic and operating  conditions.  If net capitalized  costs
exceed this limit,  the excess is charged to  operations  through  depreciation,
depletion and amortization.

In mid-March 2004,  during the year-end close of our 2003 financial  statements,
it was  determined  that there was a  computational  error in the  ceiling  test
calculation which overstated the tax basis used in the computation to derive our
after-tax  present value  (discounted at 10%) of future net revenues from proved
reserves.  We further  determined  that this tax basis error was also present in
each of our previous ceiling test  computations  dating back to 1997. This error
only affected our after-tax  computation,  used in the ceiling test  calculation
and the  unaudited  supplemental  oil and  natural gas  disclosure,  and did not
impact our: (1) pre-tax  valuation of the present value  (discounted  at 10%) of
future net revenues from proved reserves,  (2) our proved reserve  volumes,  (3)
our EBITDA or our future cash flows from  operations,  (4) our net  deferred tax
liability, (5) our estimated tax basis in oil and natural gas properties, or (6)
our estimated tax net operating losses.

After discovering this  computational  error, the ceiling tests for all quarters
since 1997 were  recomputed and it was determined  that no write-down of our oil
and  natural  gas  assets was  necessary  in any of the years from 1997 to 2003.
Additionally,  no write-down of our oil and natural gas assets was necessary for
the six months ended June 30, 2004. However,  based upon the oil and natural gas
prices in effect on December 31, 2001,  March 31, 2003 and  September  30, 2003,
the unamortized cost of oil and natural gas properties  exceeded the cost center
ceiling.  As permitted by full cost  accounting  rules,  improvements in pricing
and/or the addition of proved


                                       22


reserves  subsequent to those dates sufficiently  increased the present value of
our oil and natural gas assets and removed the  necessity to record a write-down
in these  periods.  Using the prices in effect  and  estimated  proved  reserves
existing on December  31,  2001,  March 31, 2003 and  September  30,  2003,  the
after-tax  write-down would have been approximately $6.3 million,  $1.0 million,
and $6.3 million,  respectively,  had we not taken into account these subsequent
improvements. These improvements at September 30, 2003 included estimated proved
reserves  attributable  to our Shady Side #1 well.  Because of the volatility of
oil and  natural  gas  prices,  no  assurance  can be  given  that  we will  not
experience a write-down in future periods.

In  connection  with  our  June  30,  2004  ceiling  test  computation,  a price
sensitivity study also indicated that a 20% increase in commodity prices at June
30, 2004 would have  increased the pre-tax  present value of future net revenues
("NPV") by approximately $36.4 million.  Conversely, a 20% decrease in commodity
prices at June 30,  2004  would  have  reduced  our NPV by  approximately  $36.3
million.  This would have caused our unamortized  cost of proved oil and natural
gas  properties  to exceed  the cost pool  ceiling,  resulting  in an  after-tax
write-down of approximately $6.8 million.  The aforementioned  price sensitivity
and NPV is as of June 30, 2004 and, accordingly,  does not include any potential
changes in reserves  due to third  quarter 2004  performance,  such as commodity
prices, reserve revisions and drilling results.

Under the full cost  method of  accounting,  the  depletion  rate is the current
period  production  as a percentage of the total proved  reserves.  Total proved
reserves  include both proved  developed and proved  undeveloped  reserves.  The
depletion rate is applied to the net book value and estimated future development
costs to calculate the depletion expense.

We have a significant amount of proved undeveloped reserves, which are primarily
oil reserves.  We had 44.9 Bcfe and, based on internal  estimates,  55.1 Bcfe of
proved  undeveloped  reserves,  representing  64%  and 64% of our  total  proved
reserves at December  31, 2003 and June 30, 2004,  respectively.  As of December
31,  2003  and June 30,  2004,  a large  portion  of  these  proved  undeveloped
reserves,  or  approximately  43.9  Bcfe,  are  attributable  to our  Camp  Hill
properties that we acquired in 1994. The estimated future  development  costs to
develop  our  proved  undeveloped  reserves  on our  Camp  Hill  properties  are
relatively  low, on a per Mcfe basis,  when  compared  to the  estimated  future
development  costs to develop our proved  undeveloped  reserves on our other oil
and natural gas properties. Furthermore, the average depletable life of our Camp
Hill properties is considerably higher, or approximately 15 years, when compared
to the  depletable  life of our  remaining  oil and  natural gas  properties  of
approximately 2.25 years. Accordingly, the combination of a relatively low ratio
of future  development  costs and a relatively  long depletable life on our Camp
Hill  properties has resulted in a relatively low overall  historical  depletion
rate and DD&A expense.  This has resulted in a capitalized cost basis associated
with  producing  properties  being  depleted  over  a  longer  period  than  the
associated  production and revenue stream.  It has also resulted in the build-up
of nondepleted  capitalized  costs  associated  with  properties  that have been
completely produced out.

We expect our  relatively  low  historical  depletion rate condition to continue
until the high  level of  nonproducing  reserves  to total  proved  reserves  is
reduced  and the  average  life of our proved  developed  reserves  is  extended
through  development  drilling  and/or the  significant  addition  of new proved
producing  reserves  through  acquisition or exploration.  If our level of total
proved reserves and current prices were both to remain constant,  this continued
build-up of  capitalized  costs  increases  the  probability  of a ceiling  test
write-down.

We depreciate other property and equipment using the straight-line  method based
on estimated useful lives ranging from five to 10 years.

Oil and Natural Gas Reserve Estimates

The reserve data included in this document are estimates prepared by Ryder Scott
Company and Fairchild & Wells, Inc.,  Independent  Petroleum Engineers.  Reserve
engineering is a subjective process of estimating  underground  accumulations of
hydrocarbons  that cannot be measured in an exact manner.  The process relies on
interpretation of available  geologic,  geophysical,  engineering and production
data.  The extent,  quality and  reliability  of this data can vary. The process
also requires  certain  economic  assumptions  regarding  drilling and operating
expense, capital expenditures, taxes and availability of funds. The SEC mandates
some of these  assumptions  such as oil and  natural  gas prices and the present
value discount rate.

Proved reserve estimates prepared by others may be substantially higher or lower
than these estimates. Because these estimates depend on many assumptions, all of
which may differ from actual results,  reserve quantities actually recovered may
be  significantly  different  than  estimated.  Material  revisions  to  reserve
estimates may be made depending on the results of drilling,  testing,  and rates
of production.



                                       23


You  should not assume  that the  present  value of future net cash flows is the
current market value of our estimated  proved  reserves.  In accordance with SEC
requirements,  we based the  estimated  discounted  future  net cash  flows from
proved reserves on prices and costs on the date of the estimate.

Our rate of  recording  depreciation,  depletion  and  amortization  expense for
proved properties  depends on our estimate of proved reserves.  If these reserve
estimates decline, the rate at which we record these expenses will increase.

Derivative Instruments and Hedging Activities

Upon  entering  into  a  derivative   contract,   we  designate  the  derivative
instruments as a hedge of the variability of cash flow to be received (cash flow
hedge).  Changes in the fair value of a cash flow  hedge are  recorded  in other
comprehensive  income  to  the  extent  that  the  derivative  is  effective  in
offsetting changes in the fair value of the hedged item. Any  ineffectiveness in
the  relationship  between the cash flow hedge and the hedged item is recognized
currently in income.  Gains and losses accumulated in other comprehensive income
associated  with the cash  flow  hedge are  recognized  in  earnings  as oil and
natural  gas  revenues  when  the  forecasted  transaction  occurs.  All  of our
derivative  instruments  at December 31, 2003 and June 30, 2004 were  designated
and effective as cash flow hedges.

When hedge  accounting is discontinued  because it is probable that a forecasted
transaction  will not occur,  the derivative  will continue to be carried on the
balance  sheet at its fair value and gains and losses that were  accumulated  in
other comprehensive  income will be recognized in earnings  immediately.  In all
other situations in which hedge accounting is discontinued,  the derivative will
be carried at fair value on the balance  sheet with  future  changes in its fair
value recognized in future earnings.

We typically use fixed rate swaps and costless  collars to hedge our exposure to
material  changes in the price of natural gas and oil. We formally  document all
relationships  between hedging instruments and hedged items, as well as our risk
management  objectives and strategy for undertaking  various hedge transactions.
This process  includes  linking all  derivatives  that are designated  cash flow
hedges to forecasted transactions.  We also formally assess, both at the hedge's
inception  and on an ongoing  basis,  whether the  derivatives  that are used in
hedging transactions are highly effective in offsetting changes in cash flows of
hedged transactions.

Our Board of Directors sets all of our hedging policy,  including volumes, types
of instruments  and  counterparties,  on a quarterly  basis.  These policies are
implemented  by  management  through  the  execution  of trades  by  either  the
President or Chief Financial  Officer after  consultation and concurrence by the
President,  Chief  Financial  Officer  and  Chairman  of the  Board.  The master
contracts  with the authorized  counterparties  identify the President and Chief
Financial Officer as the only representatives  authorized to execute trades. The
Board of  Directors  also  reviews the status and results of hedging  activities
quarterly.

Income Taxes

Under  Statement of Financial  Accounting  Standards  No. 109 ("SFAS No.  109"),
"Accounting for Income Taxes," deferred income taxes are recognized at each year
end for the future tax  consequences  of  differences  between  the tax bases of
assets and liabilities and their financial  reporting  amounts based on tax laws
and statutory tax rates  applicable to the periods in which the  differences are
expected to affect taxable income.  Valuation  allowances are  established  when
necessary  to  reduce  the  deferred  tax  asset to the  amount  expected  to be
realized.

Contingencies

Liabilities  and other  contingencies  are recognized upon  determination  of an
exposure,  which when analyzed  indicates that it is both probable that an asset
has been  impaired or that a liability  has been incurred and that the amount of
such loss is reasonably estimable.

Volatility of Oil and Natural Gas Prices

Our revenues, future rate of growth, results of operations,  financial condition
and  ability  to  borrow  funds or  obtain  additional  capital,  as well as the
carrying value of our properties,  are  substantially  dependent upon prevailing
prices of oil and natural gas.

We periodically  review the carrying value of our oil and natural gas properties
under  the  full  cost  accounting  rules  of the  Commission.  See  "--Critical
Accounting Policies and Estimates--Oil and Natural Gas Properties."

Total oil hedged under swaps and collars  during the three months ended June 30,
2003 and 2004 were 63,300 Bbls and 27,300 Bbls, respectively.  Total natural gas
hedged  under swaps and collars  during the three months ended June 30, 2003 and
2004 were 819,000


                                       24


MMBtu and  1,001,000  MMBtu,  respectively.  Total oil  hedged  under  swaps and
collars during the six months ended June 30, 2003 and 2004 were 126,300 Bbls and
54,300  Bbls,  respectively.  Total  natural gas hedged  under swaps and collars
during the six  months  ended June 30,  2003 and 2004 were  1,349,000  MMBtu and
1,727,000 MMBtu, respectively. The net losses realized by the Company under such
hedging  arrangements were $0.4 and $0.5 million for the three months ended June
30,  2003 and  2004,  respectively,  and are  included  in oil and  natural  gas
revenues. The net losses realized by the Company under such hedging arrangements
were $1.7  million and $0.4 million for six months ended June 30, 2003 and 2004,
respectively, and are included in oil and natural gas revenues.

To mitigate some of our commodity price risk, we engage  periodically in certain
other limited  hedging  activities.  For instance,  during the second quarter of
2003,  we  acquired  options to sell 6,000  MMBtu of natural gas per day for the
period July 2003 through  September 2003 (552,000  MMBtu) at $8.00 per MMBtu for
approximately  $119,000.  We acquired these options to protect its cash position
against  potential  margin calls on certain  natural gas derivative due to large
increases  in the  price of  natural  gas.  These  options  were  classified  as
derivatives.  The costs were  recorded as a reduction of natural gas revenues as
the options expired.

As of December 31, 2003 and June 30, 2004, $0.2 million and $0.5 million, net of
tax of $0.1  million and $0.3  million,  respectively,  remained in  accumulated
other comprehensive income related to the valuation of our hedging positions.

While the use of hedging  arrangements limits the downside risk of adverse price
movements, it may also limit our ability to benefit from increases in the prices
of natural gas and oil. We enter into the  majority of our hedging  transactions
with two  counterparties  and have a  netting  agreement  in  place  with  those
counterparties.  We do not obtain  collateral  to  support  the  agreements  but
monitor the financial viability of counterparties and believe our credit risk is
minimal on these transactions.  Under these arrangements,  payments are received
or made based on the differential  between a fixed and a variable product price.
These  agreements  are settled in cash at  expiration  or exchanged for physical
delivery contracts. In the event of nonperformance, we would be exposed again to
price risk. We have some risk of financial  loss because the price  received for
the product at the actual physical delivery point may differ from the prevailing
price at the delivery point required for settlement of the hedging  transaction.
Moreover,  our  hedging  arrangements  generally  do  not  apply  to  all of our
production and thus provide only partial price  protection  against  declines in
commodity prices. We expect that the amount of our hedges will vary from time to
time.

Our natural gas  derivative  transactions  are generally  settled based upon the
average  of the  reporting  settlement  prices on the  NYMEX for the last  three
trading days of a particular contract month. Our oil derivative transactions are
generally settled based on the average reporting  settlement prices on the NYMEX
for each trading day of a particular calendar month. For the month of June 2004,
a $0.10  change in the price per Mcf of gas sold would have  changed  revenue by
$49,000.  A $0.70  change  in the price per  barrel  of oil would  have  changed
revenue by $18,000.

The table below  summarizes our total natural gas production  volumes subject to
derivative  transactions  during  the six  months  ended  June 30,  2004 and the
weighted average NYMEX reference price for those volumes.

       ITEM 3 - QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK



For   information   regarding  our  exposure  to  certain   market  risks,   see
"Quantitative  and Qualitative  Disclosures about Market Risk" in Item 7A of our
Annual  Report on Form 10-K for the year ended  December 31, 2003 except for the
Company's hedging activity subsequent to December 31, 2003 as described above in
"Volatility of Oil and Natural Gas Prices." There have been no material  changes
to the  disclosure  regarding  our exposure to certain  market risks made in the
Annual Report. For additional information regarding our long-term debt, see Note
4 of the Notes to Unaudited  Consolidated Financial Statements in Item 1 of Part
I of this Quarterly Report on Form 10-Q.

                                       27


                        ITEM 4 - CONTROLS AND PROCEDURES



In  accordance  with  Exchange  Act Rules  13a-15 and 15d-15,  we carried out an
evaluation,  under the  supervision  and with the  participation  of management,
including  our Chief  Executive  Officer  and Chief  Financial  Officer,  of the
effectiveness  of our  disclosure  controls and  procedures as of the end of the
period covered by this report.  Based on that  evaluation,  our Chief  Executive
Officer and Chief Financial Officer  concluded that our disclosure  controls and
procedures  were effective as of June 30, 2004 to provide  reasonable  assurance
that  information  required to be  disclosed  in our reports  filed or submitted
under the Exchange Act is recorded,  processed,  summarized and reported  within
the time periods specified in the Securities and Exchange Commission's rules and
forms.

Except as set forth  below,  there has been no change in our  internal  controls
over financial  reporting  that occurred  during the three months ended June 30,
2004 that has materially affected, or is reasonably likely to materially affect,
our  internal  controls  over  financial   reporting.   Management  has  and  is
implementing  procedures and controls to address the following  deficiencies and
enhance the reliability of our internal control procedures:  (1) the presence of
underlying  errors  in the tax basis  utilized  in our full  cost  ceiling  test
computations  and certain  disclosures  and the lack of underlying  detailed tax
basis  documentation  which  adversely  impacted  our  ability to  evaluate  the
appropriateness of the tax basis (see  "Management's  Discussion and Analysis of
Financial Condition and Results of Operations -- Critical Accounting Policies --
Oil and Natural Gas  Properties")  and (2) the  sufficiency of review applied to
the financial statement close process and account reconciliation.
