                       DEVX ENERGY, INC. AND SUBSIDIARIES
              NOTES TO CONSOLIDATED CONDENSED FINANCIAL STATEMENTS
                               SEPTEMBER 30, 2001
                                   (UNAUDITED)


1.  BASIS OF PRESENTATION

The accompanying consolidated financial statements include the accounts of DevX
Energy, Inc. and its wholly owned subsidiaries (collectively, the "Company")
after elimination of all significant intercompany balances and transactions. The
financial statements have been prepared in conformity with generally accepted
accounting principles which require management to make estimates and assumptions
that affect the amounts reported in the financial statements and accompanying
notes. While management has based their assumptions and estimates on the facts
and circumstances currently known, final amounts may differ from such estimates.

The interim financial statements contained herein are unaudited but, in the
opinion of management, include all adjustments (consisting only of normal
recurring entries) necessary for a fair presentation of the financial position
and results of operations of the Company for the periods presented. The results
of operations for the three months and the nine months ended September 30, 2001
are not necessarily indicative of the operating results for the year ending
December 31, 2001. Moreover, these financial statements do not purport to
contain complete disclosure in conformity with generally accepted accounting
principles and should be read in conjunction with the Company's Annual Report on
Form 10-K for the transition period ended December 31, 2000.

2.  DERIVATIVES

The Company utilizes certain derivative financial instruments -- primarily
swaps, floors and collars -- to reduce the risk of adverse changes in future oil
and natural gas prices. Effective July 1, 2000, the Company adopted Statement of
Financial Accounting Standards No. 133, Accounting for Derivative Instruments
and Hedging Activities (SFAS No. 133), which requires the Company to recognize
all derivatives on the balance sheet at fair value. The Company estimates fair
value based on quotes obtained from the counter-parties to the derivative
contracts. The Company recognizes the fair value of derivative contracts that
expire in less than one year as current assets or liabilities. Those that expire
in more than one year are recognized as long-term assets or liabilities.
Derivatives that are not accounted for as hedges are adjusted to fair value
through income. If the derivative is designated as a hedge, depending on the
nature of the hedge, changes in fair value are either offset against the change
in fair value of the hedged assets, liabilities or firm commitments through
earnings or recognized in other comprehensive income until the hedged item is
recognized in earnings.



                                       4
<PAGE>


The Company has designated a natural gas swap as a cash flow hedge. For
derivatives classified as cash flow hedges, changes in fair value are recognized
in other comprehensive income until the hedged item is recognized in earnings.
The ineffective portion of any change in the fair value of a derivative
designated as a hedge is immediately recognized in earnings. Hedge effectiveness
is measured quarterly based on the relative fair value between the derivative
contract and the hedged item over time. During the three months ended September
30, 2001, the Company recognized a decrease in the derivative liability and an
associated decrease in other comprehensive loss totaling approximately
$2,405,000. During the nine months ended September 30, 2001, the Company
recognized a decrease in the derivative liability and an associated decrease in
other comprehensive loss totaling approximately $10,467,000. As of September 30,
2001, other current assets included $738,000 and other assets include $1,699,000
related to the fair value of derivative contracts.

During the three and nine months ended September 30, 2001, the Company
recognized non-cash gains of $535,000 and $3,730,000, respectively, in earnings
related to the net change in fair value of derivative contracts which have not
been designated as hedges.

During the three months ended September 30, 2001, the Company received $464,000
and for the nine months ended September 30, 2001, the Company paid $3,428,000 in
cash settlements on its natural gas hedges, which are included in net profits
and royalty interests.

3.  COMPREHENSIVE INCOME

Comprehensive income is defined as the change in equity of a business enterprise
during a period from transactions and other events and circumstances from
non-owner sources. For the three months ended September 30, 2001, the Company's
comprehensive income differed from net income by approximately $2,405,000
related to the change in fair value of a natural gas swap contract designated as
a hedge. For the three months ended September 30, 2000, the Company's
comprehensive income differed from net income by $8,866,000. For the nine-month
period ending September 30, 2001, the Company's comprehensive income differed
from net income by approximately $10,467,000 related to the change in fair
market value of a natural gas swap contract designated as a hedge. For the nine
months ended September 30, 2000, the Company's comprehensive income differed
from net income by $8,866,000.

</Table>

Weighted average common shares outstanding and losses per common share for the
three and nine months ended September 30, 2000 have been restated for the
effects of a 156-to-1 reverse stock split.

5. CEILING TEST WRITEDOWN

Based on oil and natural gas prices in effect on September 30, 2001, a ceiling
test writedown in the amount of $37.8 million would have been required to be
charged against earnings. Due to the increases in natural gas prices subsequent
to September 30, 2001, this writedown was not recorded. However, if prices
decline to third quarter levels at year end, such an adjustment will be
required.

6. SUBSEQUENT EVENT

The Company announced on November 13, 2001 that it has entered into a definitive
agreement which provides for a wholly owned subsidiary of Comstock Resources,
Inc. to acquire the Company in a transaction in which DevX shareholders would
receive $7.32 in cash per DevX share.

The acquisition will be effected by a first step cash tender offer for all of
the Company's outstanding common stock. The tender offer is expected to commence
on November 15, 2001 and to remain open for at least 20 business days. The
tender offer will be followed by a merger in which shareholders whose shares are
not acquired in the tender offer will receive $7.32 per share in cash. The offer
is conditioned on,


                                       6
<PAGE>


among other things, greater than 50% of the Company's outstanding shares being
tendered. There is no assurance that a transaction will be completed.

----------

(1)  Oil and natural gas sales and production expenses related to net profits
     interests have been presented as if such net profits interests had been
     accounted for as working interests, net of cash settlements on hedges.

(2)  EBITDA represents earnings before interest expense, income taxes,
     depreciation, depletion and amortization expense, and excludes interest and
     other income, change in derivative fair value and cumulative effect of
     accounting change. EBITDA is not a measure of income or cash flows in
     accordance with generally accepted accounting principles, but is presented
     as a supplemental financial indicator as to our ability to service or incur
     debt. EBITDA is not presented as an indicator of cash available for
     discretionary spending or as a measure of liquidity. EBITDA may not be
     comparable to other similarly titled measures of other companies. Our
     credit agreement requires the maintenance of specified EBITDA ratios.
     EBITDA should not be considered in isolation or as a substitute for net
     income, operating cash flow or any other measure of financial performance
     prepared in accordance with generally accepted accounting principles or as
     a measure of our profitability or liquidity.

(3)  Interest charges payable on outstanding debt obligations.

(4)  Depreciation, depletion and amortization includes $175,000 and $426,000 of
     amortized deferred charges related to debt obligations for the three months
     ended September 30, 2001 and 2000, respectively. Depreciation, depletion
     and amortization includes $573,000 and $1,250,000 of amortized deferred
     charges related to debt obligations and $0 and $44,000 of amortized
     deferred charges related to the Company's natural gas price-hedging program
     for the nine months ended September 30, 2001 and 2000, respectively.

Statements and related Notes thereto included herein.


THE THREE MONTHS ENDED SEPTEMBER 30, 2001 COMPARED TO THE THREE MONTHS ENDED
SEPTEMBER 30, 2000

RESULTS OF OPERATIONS

The following discussion and analysis reflects the operating results as if the
net profits interests were working interests. We believe that this will provide
the readers of the report with a more meaningful understanding of the underlying
operating results and conditions for the period.

REVENUES: Our total revenues decreased by $3.5 million, or 31%, to $7.9 million
for the three months ended September 30, 2001 from $11.4 million during the
comparable period in 2000. Natural gas contributed 88% of our total revenues for
the September 2001 quarter and 87% during the September 2000 quarter.

Our production of both oil and natural gas decreased for third quarter 2001
compared with third quarter 2000. Excessive leverage and depressed natural gas
prices during 1999 and the first half of 2000 resulted in our curtailing capital
spending and selling certain producing properties during those periods. Further,
and for similar reasons, we have made no acquisitions of producing properties
since April 1998. As a result, our production volumes have declined from third
quarter 2000 levels. Improved natural gas prices


                                       9
<PAGE>


and completion of our recapitalization during the second half of 2000 have
allowed us to increase our capital spending activity, beginning during the third
quarter 2000. Approximately 35% of our 2001 capital expenditure program was used
to develop our Kentucky property. This property was shut-in on June 4, 2001 due
to market factors resulting in no production volumes being realized to date
relating to this year's investment. A new market for this gas was established in
November 2001. As a result of our drilling program in the Gilmer field,
production from the field was 1 Bcf, up 25% from the 0.8 Bcf we produced during
the third quarter 2000.

We produced 39,000 barrels of crude oil during the three months ended September
30, 2001, a decrease of 12,000 barrels, or 24%, from the 51,000 barrels produced
during the comparable period in 2000. The decrease in oil production is due to
the Segno field not meeting production expectations as well as the divestment of
our Caprock field effective July 1, 2001, and sale of certain properties in
Martin County, Texas during the second quarter 2001.

We produced 2.3 Bcf of natural gas during the three months ended September 30,
2001, a decrease of 150 MMcf, or 6%, from the 2.4 Bcf produced during the
comparable period in 2000. The production during the third quarter of 2001 was
impacted by decreases due to natural decline and shut-in of wells in Kentucky,
offset by increased production in our Gilmer field due to the completion of new
wells.

Production in the New Albany Shale Gas field in Kentucky was curtailed in the
first half of this year due to a partial plant shutdown of the industrial market
that was purchasing our production. We were building additional gathering lines
to service existing and future wells when sales to this market were permanently
discontinued in June 2001. Our development activity in the field is ongoing. We
are currently completing the 50 wells drilled in Phase IV of the project and
will be connecting these wells to the gathering system as the wells are
completed, bringing the total gas wells in this field to 109.

On a thousand cubic feet of natural gas equivalent ("Mcfe") basis, production
for the three months ended September 30, 2001 was 2.5 Bcfe, down 0.2 Bcfe, or
8%, from the 2.7 Bcfe produced during the comparable period in 2000. Production
from properties that we owned during both periods was down 153 MMcfe, or 6%,
during the three months ended September 30, 2001 when compared to production
during the three months ended September 30, 2000.

The decrease in revenue is due to a significant industry-wide decrease in
natural gas prices. The average price per Mcf of natural gas sold by us was
$3.07 during the three months ended September 30, 2001, a decrease of $1.03 per
Mcf, or 25%, below the $4.10 per Mcf realized during the comparable period in
2000. The average price per barrel of crude oil sold by us during the three
months ended September 30, 2001 was $25.09, a decrease of $4.17 per barrel, or
14%, below the $29.26 per barrel realized during the


                                       10
<PAGE>


three months ended September 30, 2000. On a Mcfe basis, the average price
received by us during the three months ended September 30, 2001 was $3.17, a
$1.02 decrease, or 24%, below the $4.19 we received during the comparable period
in 2000.

During the three months ended September 30, 2001, we received $464,000 in cash
settlements under our natural gas price-hedging program. The net positive effect
on the average natural gas prices we received during the period was $0.21 per
Mcf. During the comparable period in 2000, we paid $1,050,000 in cash
settlements under our natural gas price-hedging program. The net negative effect
on the average natural gas prices we received during the 2000 period was $0.44
per Mcf. During the three months ended September 30, 2001, no crude oil
price-hedging contracts were in place. During the comparable period in 2000, we
paid $44,000 in cash settlements pursuant to our crude oil price-hedging
program.

SEVERANCE AND PRODUCTION TAXES: Severance and production taxes, which are based
on the revenues derived from the sale of crude oil and natural gas, were
$293,000 during the three months ended September 30, 2001 compared to $391,000
during the comparable period in 2000. This decrease of $98,000, or 25%, is
primarily the result of lower revenues due to lower prices and volumes as well
as the receipt of rebates in the Gilmer field.

On a cost per Mcfe basis, severance taxes were $0.12 per Mcfe for the three
months ended September 30, 2001 compared to $0.14 per Mcfe for the comparable
period ending September 30, 2000, a decrease of 14%.

PRODUCTION EXPENSES: Our lease operating expenses increased to $1.7 million for
the three months ended September 30, 2001, an increase of $0.5 million, or 42%,
from the $1.2 million incurred during the comparable period in 2000. This is due
to higher ad valorem taxes, increased chemical and treating costs, and higher
gathering charges relating to increased production in the Gilmer field incurred
in this period compared to the comparable period in 2000. Lease operating
expenses were $0.66 per Mcfe during the three months ended September 30, 2001,
an increase of $0.22, or 50%, from the $0.44 per Mcfe incurred during the
comparable period in 2000. The increase in average costs per unit is a result of
the higher costs mentioned above combined with lower production volumes.

DEPLETION, DEPRECIATION AND AMORTIZATION EXPENSE: Depletion and oil field
equipment related depreciation costs were $2.4 million for the three months
ended September 30, 2001, an increase of 14% over the $2.1 million for the
comparable period in 2000. On a Mcfe basis, depletion and oil field equipment
related depreciation was $0.94 per Mcfe during the three months, an increase of
$0.18 per Mcfe, or 24%, from the $0.76 per Mcfe during the comparable period in
2000. The increase, on a cost per Mcfe basis, is primarily due to capitalized
costs increasing at a faster rate than the reserve base.


                                       11
<PAGE>


GENERAL AND ADMINISTRATIVE EXPENSES: The increase of $1.1 million, or 122%, in
general and administrative costs for the three months ended September 30, 2001
is primarily a result of costs related to the closing of our Ottawa office.
These costs include severance payments to the former president and to the
general counsel and for costs relating to the payoff of the office lease.

INTEREST EXPENSE: Interest expense decreased by $3.1 million to $1.8 million for
the three months ended September 30, 2001 compared to $4.9 million for the three
months ended September 30, 2000. The interest expense of $1.8 million is
comprised of $1.6 million in cash interest charges and $0.2 million of amortized
deferred debt issuance costs. The decrease in interest expense resulted from the
repurchase during 2000 of $75.0 million of our senior notes and reduction in
other long-term debt of $14.0 million. During the three months ended September
30, 2000, there were $0.4 million of amortized deferred debt issuance costs
included in the interest expense of $4.9 million.

CHANGE IN DERIVATIVE FAIR VALUE: During the quarter ended September 30, 2001, we
recorded a gain of $0.5 million representing the change in fair value of our
derivative contracts that are not accounted for as hedges. During the three
months ended September 30, 2000, we recorded a loss of $0.5 million representing
the change in fair value of our derivatives contracts that are not accounted for
as hedges.

NET INCOME: For the three months ended September 30, 2001, we recorded net
income of $0.2 million or $0.02 per basic and diluted share, compared to income
of $1.8 million or $3.46 per basic and $1.08 per diluted share for 2000.
Decreased natural gas prices and increased general and administrative costs are
the primary causes of the decline.


THE NINE MONTHS ENDED SEPTEMBER 30, 2001 COMPARED TO THE NINE MONTHS ENDED
SEPTEMBER 30, 2000

RESULTS OF OPERATIONS

The following discussion and analysis reflects the operating results as if the
net profits interests were working interests. We believe that this will provide
the readers of the report with a more meaningful understanding of the underlying
operating results and conditions for the period.

REVENUES: Our total revenues increased by $3.6 million, or 13%, to $32.5 million
for the nine months ended September 30, 2001 from $28.9 million during the
comparable period in 2000. Natural gas contributed 90% of our total revenues for
the nine months ended September 2001 and 84% during the comparable period in
2000.


                                       12

Our production of both oil and natural gas decreased for the nine months ended
September 30, 2001 compared with the nine months ended September 30, 2000.
Excessive leverage and depressed natural gas prices during 1999 and the first
half of 2000 resulted in our curtailing capital spending and selling certain
producing properties during those periods. Further, and for similar reasons, we
have made no acquisitions of producing properties since April 1998. As a result,
our production volumes have declined for the nine months ended September 30,
2001 compared with the same period in 2000. Improved natural gas prices and
completion of our recapitalization during the second half of 2000 have allowed
us to increase our capital spending activity, beginning during the third quarter
2000. Approximately 35% of our 2001 capital expenditure program was used to
develop our Kentucky property. This property was shut-in on June 4, 2001 due to
market factors resulting in no production volumes being realized to date
relating to this year's investment. A new market for this gas was established in
November 2001. As a result of our drilling program in the Gilmer field,
production from this field was 2.8 Bcf, up 27% from the 2.2 Bcf produced during
the nine months ended September 30, 2000.

We produced 126,000 barrels of crude oil during the nine months ended September
30, 2001, a decrease of 35,000 barrels, or 22%, from the 161,000 barrels
produced during the comparable period in 2000. This production decrease is
primarily a result of lower than expected performance in our Segno field as well
as the divestment of our Caprock field effective July 1, 2001, and sale of
certain properties in Martin County, Texas in the second quarter 2001.

We produced 6.8 Bcf of natural gas during the nine months ended September 30,
2001, a decrease of 726 MMcf, or 10%, from the 7.5 Bcf produced during the
comparable period in 2000. This decrease consists of a decrease of 583 MMcf, or
8%, from the properties that we owned during both periods and a decrease of 143
MMcf from the properties that we sold at the end of June 2000 and in the first
half of 2001. Production during the first nine months of 2001 was impacted by
decreases due to natural decline and shut-in of wells in Kentucky offset by
increased production in the Gilmer field due to completion of new wells.

Production in the New Albany Shale Gas field in Kentucky was curtailed in the
first half of this year due to a partial plant shutdown of the industrial market
that was purchasing our production. We were building additional gathering lines
to service existing and future wells when sales to this market were permanently
discontinued in June 2001. Our development activity in the field is ongoing. We
are currently completing the 50 wells drilled in Phase IV of the project and
will be connecting these wells to the gathering system as the wells are
completed, bringing the total gas wells in this field to 109.

On a thousand cubic feet of natural gas equivalent ("Mcfe") basis, production
for the nine months ended September 30, 2001 was 7.5 Bcfe, down 0.9 Bcfe, or
11%, from the 8.4 Bcfe produced during the comparable period in 2000. Production
from properties that we owned during both periods was down


                                       13
<PAGE>


708 MMcfe, or 9%, during the nine months ended September 30, 2001 when compared
to production during the nine months ended September 30, 2000.

The increase in revenues was due to a significant, industry-wide increase in
natural gas prices which peaked during the first half of this year. Prices have
since come down to levels not seen since the first quarter of 2000. The effect
of the increased gas prices was partially offset by lower production volume and
slightly lower oil prices. The average price per barrel of crude oil sold by us
during the nine months ended September 30, 2001 was $26.45, a decrease of $1.50
per barrel, or 5%, below the $27.95 per barrel during the nine months ended
September 30, 2000. The average price per Mcf of natural gas sold by us was
$4.31 during the nine months ended September 30, 2001, an increase of $1.06 per
Mcf, or 33%, over the $3.25 per Mcf realized during the comparable period in
2000.

During the nine months ended September 30, 2001, we paid $3,428,000 in cash
settlements under our natural gas price-hedging program. The net negative effect
on the average natural gas prices we received during the period was $0.50 per
Mcf. During the comparable period in 2000, we paid $1,666,000 and amortized
$44,000 of deferred hedging costs regarding our natural gas price-hedging
program. The net negative effect on the average natural gas prices we received
during the 2000 period was $0.22 per Mcf. During the nine months ended September
30, 2001, no crude oil price hedging contracts were in place. During the
comparable period in 2000, we paid $153,000 in cash settlements pursuant to our
crude oil price-hedging program.

SEVERANCE AND PRODUCTION TAXES: Severance and production taxes, which are based
on the revenues derived from the sale of crude oil and natural gas, were
$1,174,000 during the nine months ended September 30, 2001 compared to
$1,238,000 during the comparable period in 2000. This decrease of $64,000, or
5%, is primarily the result of severance tax rebates on our Gilmer and J.C.
Martin fields received during the first nine months of 2001 offset by increased
taxes due to increased revenues.

On a cost per Mcfe basis, severance taxes were $0.16 per Mcfe for the nine
months ended September 30, 2001 compared to $0.15 per Mcfe for the comparable
period ending September 30, 2000, an increase of 7%. This increase is a result
of lower volumes offset by lower severance taxes due to rebates received in this
period.

PRODUCTION EXPENSES: Our lease operating expenses increased to $5.1 million for
the nine months ended September 30, 2001, an increase of $1.0 million, or 24%,
from the $4.1 million incurred during the comparable period in 2000. The
nine-month period ending September 30, 2001 included increased ad valorem taxes,
chemical and treating costs, and gathering charges resulting from higher
production volumes in the Gilmer field when compared to the comparable period in
2000. Lease operating expenses were $0.68


                                       14
<PAGE>


per Mcfe during the nine months ended September 30, 2001, an increase of $0.19,
or 39%, from the $0.49 per Mcfe incurred during the comparable period in 2000.
The increase in average costs per unit is a result of increased total costs and
lower production volumes.

DEPLETION, DEPRECIATION AND AMORTIZATION EXPENSE: Depletion and oil field
equipment related depreciation costs were $7.0 million for the nine months ended
September 30, 2001, an increase of 11% over the $6.3 million for the comparable
period in 2000. On a Mcfe basis, depletion and oil field equipment related
depreciation was $0.93 per Mcfe during the nine months, an increase of $0.19 per
Mcfe, or 26%, from the $0.74 Mcfe per during the comparable period in 2000. The
increase, on a cost per Mcfe basis, is primarily due to capitalized costs
increasing at a faster rate than the reserve base.

GENERAL AND ADMINISTRATIVE EXPENSES: The increase of $1.7 million, or 67%, in
general and administrative costs for the nine months ending September 30,
2001 is primarily a result of costs incurred relating to the closing of our
Ottawa office as well as increased audit fees and engineering costs.

INTEREST EXPENSE: Interest expense decreased by $8.8 million to $5.5 million for
the nine months ended September 30, 2001 compared to $14.3 million for the nine
months ended September 30, 2000. The interest expense of $5.5 million is
comprised of $4.9 million in cash interest charges and $0.6 million of amortized
deferred debt issuance costs. The decrease in interest expense resulted from the
repurchase of $75.0 million of our senior notes and reduction in other long-term
debt of $14.0 million. During the nine months ended September 30, 2000, there
were $1.3 million of amortized deferred debt issuance costs included in the
interest expense of $14.3 million.

CHANGE IN DERIVATIVE FAIR VALUE: During the nine months ended September 30,
2001, we recorded a gain of $3.7 million representing the change in fair value
of our derivative contracts that are not accounted for as hedges. During the
comparable period in 2000, we recorded a loss of $0.5 million representing the
change in fair value of our derivative contracts that are not accounted for as
hedges.

NET INCOME: For the nine months ended September 30, 2001, we recorded net income
of $8.6 million or $0.67 per basic and diluted share, compared to net income of
$0.4 million or $0.91 and $0.34 per basic and diluted share, respectively, for
2000. The reduction of debt and increased natural gas prices are the primary
causes of the significantly improved results.

LIQUIDITY AND CAPITAL RESOURCES

GENERAL

During the year ended December 31, 1999 and the first half of 2000, our
acquisition and development spending were significantly curtailed as a result of
the combined impact of depressed natural gas prices and excessive leverage. We
also sold producing properties during those periods. As a result of reduced
spending combined with property sales, our production rates have been declining.
During 1999, we invested $7.5 million in development activities and sold
producing properties for proceeds of $10.2 million. During the first half of
2000, we invested $4.0 million in development of our properties and sold
producing properties for proceeds of $3.4 million.

Increasing natural gas prices during the last half of 2000 and completion of our
recapitalization during October 2000 enabled us to increase our capital spending
activities. During the last half of 2000, we spent $9.1 million in capital
activities. As planned, our capital spending level has continued to grow as we
invested $20.6 million during the first nine months of 2001, including $3.1
million in exploration activities. Our plans for the remainder of 2001 call for
additional capital spending of approximately $10 million, of which,
approximately 20% is allocated to exploration activities. The increased spending
levels are intended to increase our reserves and production rates. We have
already seen production increases in the Gilmer field due to our accelerated
drilling program, and we expect to see increased production in our Kentucky
properties as wells are placed on production during November 2001.

We have planned development and exploitation activities for all of our major
operating areas. We plan to spend a total of approximately $30 million in
capital activities during 2001. During the nine months ended September 30, 2001,
we have spent $20.6 million and have a further $14.2 million contractually
committed, some of which will occur during 2002. Of the total planned capital
expenditures for the year, approximately 17% is allocated to exploration
activities. We believe our existing cash balances and cash flow from operations
combined with our existing credit facility will be sufficient to fund our
planned exploration, development and exploitation activities for 2001. In
addition, we are continuing to evaluate oil and natural gas properties for
future acquisition. Historically, we have used the proceeds from the sale of our
securities in the private equity market and borrowings under our credit
facilities to raise cash to fund acquisitions or repay indebtedness incurred for
acquisitions. We have also used our securities as a medium of exchange for other
companies' assets in connection with acquisitions. However, there can be no
assurance that such sources will be available to us to meet our budgeted capital
spending. Furthermore, our ability to borrow other than under the amended and
restated credit agreement with Ableco Finance LLP and Foothill Capital
Corporation is subject to restrictions imposed by our credit agreement and the
indenture governing our senior notes. If we cannot secure additional funds for
our planned development and exploitation activities, then we will be required to
delay or reduce substantially our development and exploitation efforts.

Total current assets decreased by $4.5 million from December 31, 2000 to
September 30, 2001 as oil and gas sales receivable fell as a result of lower
natural gas prices.

Part of the Company's strategy to increase shareholder value is to actively seek
corporate acquisitions and mergers. On April 24, 2001, we announced that we had
received written indications of interest that could result in the merger or sale
of the Company. At the same time, we announced that we had instructed our
investment bankers to evaluate those expressions of interest as well as other
merger or sale alternatives. On November 13, 2001, we announced that we entered
into a definitive agreement which provides for a wholly owned subsidiary of
Comstock Resources, Inc. to acquire DevX in a transaction in which DevX
shareholders would receive $7.32 in cash per DevX share.

The acquisition will be effected by a first step cash tender offer for all of
DevX's outstanding common stock. The tender offer is expected to commence on
November 15, 2001 and to remain open for at least 20 business days. The tender
offer will be followed by a merger in which shareholders whose shares are not
acquired in the tender offer will receive $7.32 per share in cash. The offer is
conditioned on, among other things, greater than 50% of the outstanding DevX
shares being tendered. There is no assurance that a transaction will be
completed.

SOURCES OF CAPITAL

We have a credit agreement with Ableco Finance LLC and Foothill Capital
Corporation which allows for borrowings up to $50 million, subject to borrowing
base limitations, from such lenders to fund, among other things, development and
exploitation expenditures, acquisitions and general working capital. Our
borrowing base under the credit agreement is currently $43.5 million. As of
November 1, 2001, under this facility, we had no indebtedness outstanding, had
$0.1 million reserved to secure a letter of credit, and were permitted to borrow
an additional $43.4 million. Under the credit agreement, we have provided a
first lien on all of our assets to secure our obligations under the agreement.
The credit agreement matures on April 22, 2003. There are no scheduled principal
repayments. The credit agreement bears interest as follows:

o    When the borrowings are less than $30 million or borrowings are less than
     67% of the borrowing base as defined in the agreement, bank prime plus 2%;

o    When the borrowings are $30 million or greater and borrowings exceed 67% of
     the borrowing base as defined in the agreement, bank prime plus 3.5%;

o    On amounts securing letters of credit issued on our behalf, 3%.

The credit agreement contains certain affirmative and negative financial
covenants, including maintaining interest coverage ratio greater than 1, a
minimum of 1.5-to-1 working capital ratio (calculated as set out in the credit
agreement) and a $30 million annual limit on capital spending. The Company has
been in compliance with all covenants during the nine months ended September 30,
2001.

We have a letter of credit outstanding under the credit agreement in the amount
of $0.1 million, as of November 1, 2001, to secure a swap exposure. The letter
of credit has the effect of reducing our credit availability under the credit
agreement.

Effective as of August 31, 2001 we issued warrants to purchase a total of
265,000 shares of our common stock to two former employees as part of their
severance packages [see Part II, Item 5 - Other Information]. The warrants carry
an exercise price of $7.00 per share. The warrants become exercisable in stages
over the period ending October 27, 2002 and all of them become exercisable
immediately in the event of a change of control of the Company. The warrants
expire in February and March 2003.


USES OF CAPITAL

During the period since our inception in August 1994 through April 1998, our
primary method of replacing our production and increasing our reserves was
through acquisitions. Since April 1998, our primary method of replacing
production and enhancing our reserves has been through the development and
exploitation of our oil and natural gas properties. We have recently entered
into two exploration joint ventures and expect to allocate approximately 17% of
our 2001 capital spending to exploration activities. We expect to spend
approximately $30 million on capital spending during 2001 for exploitation,
development and exploration projects. As of September 30, 2001, we are
contractually obligated to fund a further $14.2 million in capital expenditures,
some of which will occur during 2002. We believe that cash on hand, cash flow
from operations and our credit agreement will be sufficient to fund our planned
activities. However, our cash flow from operations is significantly affected by
the uncertainty of commodity prices. If there were a significant, protracted
decline in prices, we would evaluate our projects and may delay or defer some of
our planned activities. During the nine months ended September 30, 2001, we
recorded $20.6 million in capital expenditures. Of this amount, $3.1 million
relate to exploration activities with the balance of $17.5 million used in
property development.

On September 4, 2001, we announced a stock buy back program of up to one million
shares of our outstanding common stock. The program will be available over a
period of approximately 16 months ending on December 31, 2002. The Company
expects to fund the repurchase program from cash on hand. The repurchase program
is being implemented on the open market or in privately negotiated transactions
from time to time. Repurchases of stock will occur at management's discretion,
depending upon price and availability. In the quarter ending September 30, 2001,
we repurchased a total of 100,000 shares of common stock in the open market at
an average price of $5.25 per share. All shares repurchased under this program
will be held as treasury shares, which may be used to satisfy our current and
near term requirements under our equity incentive and other benefit plans and
for other corporate purposes. This program was suspended in conjunction with the
Company's discussions with Comstock and will remain suspended during the
pendency of the tender offer contemplated in the Company's agreement with
Comstock.

HEDGING ARRANGEMENTS, LETTERS OF CREDIT AND INSURANCE

Some of our hedging arrangements contain a "cap" whereby we must pay the
counter-party if oil or natural gas prices exceed the specified price in the
contract. We are required to maintain letters of credit with our
counter-parties, and we may be required to provide additional letters of credit
if prices for oil and natural gas futures increase above the "cap" prices. The
amount of letters of credit required under the hedging arrangements is a
function of the market value of oil and natural gas prices and the volumes of
oil and natural gas subject to the hedging contract. As a result, the amount of
the letters of credit will fluctuate with the market prices of oil and natural
gas. These letters of credit are issued pursuant to our credit agreement and as
a result utilize some of our borrowing capacity, reducing our remaining
available funds under our credit agreement. Our credit agreement permits up to
$12 million in letters of credit. As of November 1, 2001, we have provided $0.1
million in letters of credit related to our hedge contracts containing "caps."

OTHER CONTINGENCIES

On September 11, 2001, the United States was the target of terrorist attacks of
unprecedented scope. On October 7, 2001, the United States commenced military
action in Afghanistan in response to these attacks. These developments have
caused instability in the world's financial and insurance markets. In addition,
these developments could lead to increased volatility in prices for crude oil
and natural gas. Insurance premiums charged for some or all of the coverages the
Company has historically maintained could increase materially, or the coverages
could be unavailable in the future. These developments could have an adverse
effect on our business and on our share price.

INFLATION

Although inflation has not had a significant impact on our results of operations
during the past several years, oil and gas production and development costs,
lease acquisition and operating costs, labor availability, drilling costs
(including costs of pipe, drill fluids and rig crews) and availability of rigs,
fluctuate in response to overall industry conditions and demand for leases and
rigs. Moreover, the prices we receive for our production fluctuate upward and
downward, often significantly and often in a short period of time. This can and
will affect our revenues from quarter to quarter.

CHANGES IN PRICES AND HEDGING ACTIVITIES

Annual average oil and natural gas prices have fluctuated significantly over the
last two years. The table below sets out our weighted average price per barrel
of oil and the weighted average price per Mcf of natural gas, the impact of our
hedging programs and the related NYMEX indices.

We have a commodity price risk management or hedging strategy that is designed
to provide protection from low commodity prices while providing some opportunity
to enjoy the benefits of higher commodity prices. We have a series of natural
gas futures contracts with various counter-parties. This strategy is designed to
provide a degree of protection from negative shifts in natural gas prices as
reported on the

At current natural gas price levels, we have a net liability to Enron related to
our hedge positions in which Enron is the counter-party. If natural gas futures
prices fall below $2.40 per MMBtu in the future, our hedge positions with Enron
would become a net asset, and we would have credit exposure to Enron to that
extent. We will continue to monitor our potential exposure with Enron.

                                OTHER INFORMATION


ITEM 5. OTHER INFORMATION

On February 13, 2001, we announced the implementation of a four-part strategy
directed at growing our asset base and increasing shareholder value. This
strategy consists of: (1) establishing an exploration program to add reserves at
competitive finding costs; (2) developing and exploiting our existing
properties; (3) pursuing selective property acquisitions; and (4) actively
seeking corporate acquisitions and mergers. On April 24, 2001, we announced that
we had received written indications of interest that could result in the merger
or sale of the company for cash or a combination of cash and stock. At the same
time, we announced that we had instructed our investment bankers to evaluate the
expressions of interest as well as other merger or sale alternatives to maximize
stockholder value.

On November 13, 2001, we announced that we entered into a definitive agreement
which provides for a wholly owned subsidiary of Comstock Resources, Inc. to
acquire DevX in a transaction in which DevX shareholders would receive $7.32 in
cash per DevX share.

The acquisition will be effected by a first step cash tender offer for all of
DevX's outstanding common stock. The tender offer is expected to commence on
November 15, 2001 and to remain open for at least 20 business days. The tender
offer will be followed by a merger in which shareholders whose shares are not
acquired in the tender offer will receive $7.32 per share in cash. The offer is
conditioned on, among other things, greater than 50% of the outstanding DevX
shares being tendered. There is no assurance that a transaction will be
completed.

On September 4, 2001, we announced a stock buy back program of up to 1 million
shares of our outstanding common stock. The program will be available over a
period of approximately 16 months ending on December 31, 2002. The Company
expects to fund the repurchase program from cash on hand. The repurchase program
is being implemented on the open market or in privately negotiated transactions
from time to time. Repurchases of stock will occur at management's discretion,
depending upon price and availability. In the quarter ending September 30, 2001,
we repurchased a total of 100,000 shares of common stock in the open market at
an average price of $5.25 per share. All shares repurchased under this program
will be held as treasury shares, which may be used to satisfy our current and
near term requirements under our equity incentive and other benefit plans and
for other corporate purposes. This program was suspended in conjunction with the
Company's discussions with Comstock and will remain suspended during the
pendency of the tender offer contemplated in the Company's agreement with
Comstock.

On August 6, 2000, in connection with the Company's decision to close our
offices in Ottawa, Canada, the Board notified Mr. Munden that it required him to
relocate to Dallas on or before November 6, 2001. Mr. Munden declined to
relocate and instead elected to resign effective on August 31, 2001. As a
settlement of its obligations under Mr. Munden's employment contract, which was
to have expired on November 10, 2002, the Company entered into a termination
severance agreement with Mr. Munden under which it agreed to pay him $579,853
consisting of his Base Salary plus accrued Highest Annual Bonus through November
6, 2001 plus a severance payment equal to the sum of one year's Base Salary plus
his Highest Annual Bonus (as those capitalized terms were defined in his
employment contract) in exchange for a non-competition and non-solicitation
agreement from Mr. Munden and his general release and surrender of his options.
The termination agreement also provides that we will issue 240,000 warrants to
Mr. Munden to replace the options that he had been previously granted. The
warrants have an exercise price of $7.00 per share and will expire on September
27, 2003. In the event that a Change of Control (as defined in Mr. Munden's
employment contract) occurs at any time through March 31, 2003, the Company will
pay Mr. Munden an additional amount of two times his Base Salary and Highest
Annual Bonus (the Comstock transaction will constitute a change of control). As
part of the severance package, the Company also agreed to pay Mr. Munden an
additional cash amount of $36,086 in consideration of its obligation to maintain
certain fringe benefits that Mr. Munden would have been entitled to receive to
the end of the term had his employment contract remained in place. Mr. Munden
has agreed to make himself available as a consultant for up to 1 hour per week
for a period of 6 months following the effective date of his termination of
employment.

On August 6, 2000, in connection with our decision to close our Ottawa office,
the Board also notified Mr. Barr that it required him to relocate to Dallas on
or before November 6, 2001. Mr. Barr declined to relocate. The Company entered
into a termination severance agreement with Mr. Barr under which Mr. Barr agreed
to resign his officer positions effective August 31, 2001 and to resign his
employment on the earlier of his receipt of written notice from the Company or
November 6, 2001. As a settlement of the Company's obligations under Mr. Barr's
employment contract, the Company agreed to pay Mr. Barr the amount of $157,603
consisting of his Base Salary through November 6, 2001 plus a severance payment
equal to the sum of 1 year's Base Salary plus accrued Target Bonus (as those
capitalized terms were defined in his employment contract). In addition, the
Company agreed to issue 25,000 warrants to Mr. Barr to replace the options that
he had been previously granted. The warrants have an exercise price of $7.00 per
share and will expire on February 24, 2003. In the event that a Change of
Control (as that term is defined in Mr. Barr's employment contract) occurs at
any time through March 31, 2003, the Company will pay Mr. Barr an additional
amount of one half his annual Base Salary (the Comstock transaction will


                                       24
<PAGE>


constitute a change of control). As part of the severance package, the Company
also agreed to pay Mr. Barr an additional cash payment of $16,000 which is the
equivalent amount of the fringe benefits that he would have been entitled to
receive to the end of the term had his employment contract remained in place.
Mr. Barr's termination agreement also contains a general release and a
non-competition clause and provides for the surrender and cancellation of all
options previously granted to Mr. Barr. Mr. Barr has agreed to make himself
available as a consultant for up to 5 hours per month for a period of 12 months
following the effective date of his termination of employment.
