              ST. MARY LAND & EXPLORATION COMPANY AND SUBSIDIARIES
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                   (UNAUDITED)


                               September 30, 1998


Note 1 - Basis of Presentation

The accompanying unaudited condensed consolidated financial statements have been
prepared in accordance with generally accepted accounting principles for interim
financial information. They do not include all information and notes required by
generally  accepted  accounting  principles for complete  financial  statements.
However,  except as disclosed  herein,  there has been no material change in the
information disclosed in the notes to consolidated financial statements included
in the Annual  Report on Form 10-K of St.  Mary Land &  Exploration  Company and
Subsidiaries  (the  "Company")  for the year ended  December  31,  1997.  In the
opinion of Management, all adjustments (consisting of normal recurring accruals)
considered  necessary  for a fair  presentation  have been  included.  Operating
results for the periods presented are not necessarily  indicative of the results
that may be expected for the full year.

The accounting  policies  followed by the Company are set forth in Note 1 to the
Company's  financial  statements  in Form 10-K for the year ended  December  31,
1997. It is suggested  that these  financial  statements be read in  conjunction
with the financial statements and notes included in the Form 10-K.

Certain  amounts  in  the  1997  consolidated  financial  statements  have  been
reclassified to correspond to the 1998 presentation.

Note 2 - Investments

The Company,  through  subsidiaries,  owned an 18% interest in a venture that is
developing the  Chernogorskoye  oil field in western Siberia (the "Russian joint
venture"). The Company accounted for its investment in the Russian joint venture
under the equity method of  accounting.  In February  1997, the Company sold its
interest  in the  Russian  joint  venture  to Khanty  Mansiysk  Oil  Corporation
("KMOC"),  formerly known as Ural Petroleum Corporation.  In accordance with the
Acquisition  Agreement,  the Company  received cash  consideration of $5,608,000
before  transaction  costs,  KMOC  common  stock  valued  at  $1,869,000,  and a
receivable in a form equivalent to a retained  production payment of $10,134,000
plus interest at 10% per annum from the limited liability company formed to hold
the Russian joint venture interest.  The Company's  receivable is collateralized
by the partnership  interest sold. The Company has the right, subject to certain
conditions,  to require KMOC to purchase the Company's  receivable  from the net
proceeds of an initial  public  offering of KMOC common stock or  alternatively,
the Company may elect to convert  all or a portion of its  receivable  into KMOC
common  stock  immediately  prior to an initial  public  offering of KMOC common
stock.  The  Company  recorded a gain on the sale of the Russian  joint  venture
interest of  $9,671,000.  The  Company's  equity in income for the Russian joint
venture  for 1997  through  the date of sale was  $203,000.  Uncertain  economic
conditions  in Russia and lower oil prices have  affected the carrying  value of
the convertible  receivable.  As a result,  the Company has reduced the carrying
amount of the receivable to its minimum conversion value,  incurring a charge to
operations of $4,553,000 in the quarter ended September 30, 1998.



                                      -7-


The  Company  accounts  for  its  37%  ownership   interest  in  Summo  Minerals
Corporation ("Summo") under the equity method of accounting. For the nine months
ended September 30, 1998, the Company  recorded a loss of $612,000 as its equity
in the losses of Summo.  In May 1997,  the Company  entered into an agreement to
receive a 55% interest in Summo's Lisbon Valley Copper  Project (the  "Project")
in  return  for  the  Company  contributing  $4,000,000  in  cash,  all  of  its
outstanding  stock in Summo,  and  $8,600,000  in  letters of credit to a single
purpose company, Lisbon Valley Mining Company LLC, formed to own and operate the
Project.  Summo will contribute the property, all project permits and contracts,
$3,200,000 in cash, and a commitment for $45,000,000 of senior debt financing in
return  for a 45%  interest  in the new  company.  The  agreement  is subject to
certain  conditions,  including  project  financing.  The  Company has agreed to
provide  interim  financing of up to $2,950,000 for the Project in the form of a
loan to Summo due in June 1999.  Interest accrues on the amounts  outstanding at
the prime rate plus 1%. As of September  30, 1998,  $2,784,000  was  outstanding
under this loan. At the  Company's  option,  any principal and interest  amounts
outstanding  are  convertible  into shares of Summo common stock  anytime  after
December 31, 1998, at a conversion  price equal to the weighted  average trading
price of Summo's  common  shares for the twenty  trading  days leading up to and
including  December  31,  1998.  Upon  capitalization  of the  new  company  the
outstanding  loan principal shall  constitute a capital  contribution in partial
satisfaction  of the  Company's  capital  commitments  set out in the  May  1997
agreement,  and any accrued interest on the loan shall be forgiven. In September
1998,  Summo received final regulatory  approval to develop the Project.  Future
development  and financial  success of the Project are largely  dependent on the
market price of copper,  which is  determined in world markets and is subject to
significant  fluctuations.  Current copper prices have declined to ten-year lows
and do not justify  construction  and  development  of the Project at this time.
However,  Management believes that copper prices will recover when international
economic conditions improve.  The Company has entered into agreements to provide
interim  financing to the Project  through the balance of 1998 and will evaluate
the  Project's  future  funding  requirements  in early  1999.  There  can be no
assurance  that the Company will realize a return on its  investment in Summo or
the Project.

Note 3 - Capital Stock

On February 26, 1997, the Company closed the sale of 2,000,000  shares of common
stock at $25.00 per share.  On March 12, 1997, the Company closed the sale of an
additional  180,000  shares  pursuant  to  the  underwriters'  exercise  of  the
over-allotment  option. These transactions resulted in aggregate net proceeds of
$51,200,000.   The  proceeds  were  used  to  fund  the  Company's  exploration,
development and acquisition  programs and to repay  borrowings  under its credit
facility.

In June 1998, the Company's  shareholders approved an amendment to the Company's
Certificate  of  Incorporation  to increase the number of  authorized  shares of
Common Stock from 15,000,000 to 50,000,000.

In August 1998,  the Company's  Board of Directors  approved a stock  repurchase
program  whereby  the  Company may  purchase  from time to time,  in open market
purchases or  negotiated  sales,  up to one million  shares of its common stock.
During the third quarter the Company  repurchased  147,800  shares of its common
stock  under the  program  at a  weighted  average  price of $16.71  per  share.
Management  anticipates  that additional  purchases of shares by the Company may
occur as market conditions warrant.  Such purchases will be funded with internal
cash flow and borrowings under the Company's credit facility.

Note 4 - Recently Issued Accounting Standards

In June 1997, the Financial Accounting Standards Board ("FASB") issued Statement
of Financial  Accounting  Standards ("SFAS") No. 130,  "Reporting  Comprehensive
Income,"  effective for financial  statements for fiscal years  beginning  after
December 15, 1997. The Statement establishes standards for reporting and display
of comprehensive income and its components in financial statements. The adoption
of this  statement  will not have a material  impact on the Company's  financial
statements.

In June 1997,  the FASB issued SFAS No. 131,  "Disclosures  about Segments of an
Enterprise  and Related  Information,"  effective for financial  statements  for
fiscal years beginning after December 15, 1997. The Statement requires companies
to report  certain  information  about  operating  segments  in their  financial
statements  and certain  information  about their  products  and  services,  the
geographic areas in which they operate and their major customers. The Company is
currently reviewing the effects of the disclosure requirements of the Statement.

In February 1998, the FASB issued SFAS No. 132,  "Employer's  Disclosures  about
Pensions  and  Other  Postretirement   Benefits,"  effective  for  fiscal  years
beginning  after  December 15, 1997. The Statement  standardizes  the disclosure
requirements  for  pensions  and  other   postretirement   benefits  to  provide
information  that is more  comparable  and  concise.  The  Company is  currently
reviewing the effects of the disclosure requirements of the Statement.

In June  1998,  the  FASB  issued  SFAS  No.  133,  "Accounting  for  Derivative
Instruments and Hedging Activities," effective for all fiscal quarters of fiscal
years  beginning after June 15, 1999. The Statement  establishes  accounting and
reporting  standards for derivative  instruments,  including certain  derivative
instruments embedded in other contracts, and for hedging activities. The Company
is currently  reviewing  the effects this  Statement  will have on the financial
statements in relation to the Company's hedging activities.

Note 5 - Earnings per Share

In February  1997,  the FASB issued SFAS No. 128,  "Earnings  Per Share,"  which
requires a dual  presentation  of basic and  diluted  earnings  per  share.  The
Company  adopted SFAS No. 128  effective  December 31, 1997.  Under SFAS No. 128
basic net income per share of common stock is  calculated by dividing net income
by the weighted  average of common shares  outstanding  during each period,  and
diluted  net income per common  share of stock is  calculated  by  dividing  net
income by the weighted  average of outstanding  common shares and other dilutive
securities.  Dilutive  securities of the Company consist entirely of outstanding
options to purchase the Company's  common stock.  Because the Company had a loss
from  continuing  operations for the  three-month  and nine-month  periods ended
September 30, 1998, the outstanding options were antidilutive and were therefore
not included in the  earnings  per share  calculations  for these  periods.  The
outstanding  dilutive  securities for the three-month period ended September 30,
1997 were 145,729,  and the outstanding  dilutive  securities for the nine-month
period ended  September 30, 1997 were 114,622.  All net income of the Company is
available to common stockholders.  The adoption of SFAS No. 128 had no effect on
diluted net income per share  compared to fully  diluted net income per share as
reported  for the nine months ended  September  30, 1997 or for the three months
ended  September  30,  1997.  Restated  basic net  income per share for the nine
months  ended  September  30, 1997 was $2.05  compared to primary net income per
share of $2.03 as  reported.  Restated  basic net income per share for the three
months  ended  September  30, 1997 was $0.37  compared to primary net income per
share of $0.36 as reported.



                                      -9-


Note 6 - Income Taxes

Federal income tax benefit for 1998 and expense  for1997 differ from the amounts
that would be provided by applying the statutory U.S. Federal income tax rate to
income  or loss  before  income  taxes  primarily  due to  Section  29  credits,
percentage depletion in 1998, and the effect of state income taxes.

Note 7 - Long-Term Debt and Notes Payable

On June 30, 1998,  the Company  entered into a new  long-term  revolving  credit
agreement  that replaced the agreement  dated March 1, 1993 and amended in April
1996. The new credit  agreement  specifies a maximum loan amount of $200,000,000
and has an initial  aggregate  borrowing  base of  $115,000,000.  The lender may
periodically  re-determine  the aggregate  borrowing base. The initial  accepted
borrowing  base is  $40,000,000.  The credit  agreement  has a maturity  date of
December 31, 2005, and includes a revolving  period that matures on December 31,
2000.  The Company can elect to allocate up to 50% of available  borrowings to a
short-term  tranche  due in 364 days.  The  Company  must  comply  with  certain
covenants including maintenance of stockholders' equity at a specified level and
limitations on additional indebtedness. As of September 30, 1998 $25,200,000 was
outstanding under this credit agreement.

Effective June 30, 1998,  interest on borrowings during the revolving period and
commitment  fees on the  unused  portion  of the  accepted  borrowing  base  are
calculated as follows:

INTEREST RATES:

Debt to Capitalization Ratio                      Interest Rate
- ----------------------------                      -------------

                                       Rate + 0.5% or the Prime Rate
Greater than or equal to            The Company's  option of (a) LIBOR + 1.25% 
  0.5 to 1.0                           or (b) the higher of the Federal Funds 
                                       Rate + 0. 625% or the Prime Rate + 0.125%

COMMITMENT FEES:

Debt to Capitalization Ratio         Short-Term Tranche   Long-Term Tranche

At September 30, 1998,  the Company's  debt to  capitalization  ratio as defined
under the credit agreement was 0.19 to 1.0.



                                      -10-


Panterra, in which the Company has a 74% general partnership ownership interest,
has a separate credit  facility with a $25,000,000  borrowing base as of July 1,
1998, and $10,000,000  and $11,000,000  outstanding as of September 30, 1998 and
December 31, 1997,  respectively.  In June 1997,  Panterra entered into a credit
agreement replacing a previous agreement,  which was due March 31, 1999. The new
credit agreement  includes a two-year revolving period converting to a five-year
amortizing loan on June 30, 1999.  During the revolving period of the loan, loan
balances accrue interest at Panterra's option of either the bank's prime rate or
LIBOR plus 3/4% when the  Partnership's  debt to partners' capital ratio is less
than 30%,  up to a maximum of either the bank's  prime rate or LIBOR plus 1-1/4%
when the Partnership's debt to partners' capital ratio is greater than 100%.

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

Overview

St. Mary Land & Exploration Company ("St. Mary" or the "Company") was founded in
1908 and  incorporated  in  Delaware  in 1915.  The  Company  is  engaged in the
exploration,  development,  acquisition  and production of crude oil and natural
gas with  operations  focused in five core operating areas in the United States:
The Mid-Continent  region; the ArkLaTex region;  south Louisiana;  the Williston
Basin; and the Permian Basin.

The  Company's  objective is to build value per share by focusing its  resources
within  selected  basins  in  the  United  States  where   management   believes
established  acreage  positions,   long-standing   industry   relationships  and
specialized   geotechnical  and  engineering  expertise  provide  a  significant
competitive  advantage.   The  Company's  ongoing  development  and  exploration
programs are complemented by less predictable opportunities to acquire producing
properties having significant  exploitation  potential,  to monetize assets at a
premium and to repurchase shares at attractive values.

Internal  exploration,  drilling and production  personnel conduct the Company's
activities in the  Mid-Continent  and ArkLaTex  regions and in south  Louisiana.
Activities  in the  Williston  Basin are conducted  through  Panterra  Petroleum
("Panterra") in which the Company owns a 74% general partnership  interest.  The
Company proportionally consolidates its interest in Panterra.  Activities in the
Permian  Basin  are  primarily  contracted  through  an  oil  and  gas  property
management company with extensive experience in the basin.

The  Company's  principal  equity  investment  is  Summo  Minerals   Corporation
("Summo"), a North American copper mining company of which the Company owns 37%.
Until early 1997,  the Company  had an equity  investment  in its Russian  joint
venture.  Effective  February  12,  1997,  the Company  sold its  Russian  joint
venture. The Company accounts for its investments in Summo and the Russian joint
venture  under the equity  method and  includes  its share of the income or loss
from these entities in its consolidated results of operations.

The Company  receives  significant  royalty and working interest income from its
south Louisiana fee lands. The Company first  participated as a working interest
owner in its fee lands with the drilling and  completion of a discovery  well at
South  Horseshoe  Bayou in  February  1997.  Subsequently,  in April  1998,  the
discovery well was recompleted. In January 1998, the St. Mary Land & Exploration
No. 3 was  completed.  From  February  1997 through  September  30, 1998,  South
Horseshoe Bayou has produced  approximately  5.7 Bcf of gas and 43 MBbls of oil,
net to  the  Company's  interests.  Mechanical  problems  caused  suspension  of
production from the No. 3 well in August 1998. Management expects the well to be
shut-in  through  the  remainder  of 1998,  pending  a  recommendation  from the
operator  regarding a procedure to return the well to  production  or to abandon
it. An additional well location to the north of the No. 3 well has been selected
for drilling in early 1999. The Company owns a 25% working  interest and royalty
interests  between  approximately 19% and 22% in the South Horseshoe Bayou Field
for  combined  net  revenue  interests  of  between  approximately  37% and 40%,
depending on the depth of production.  The Company anticipates that a portion of
the  proved  reserves  attributed  to South  Horseshoe  Bayou may be  reduced or
reclassified.  The  magnitude  of any  potential  reserve  adjustments  at South
Horseshoe  Bayou will not be known until early 1999 following  completion of the
annual review of the Company's reserves by Ryder Scott and Company.

During  1997 and  through  the first nine  months of 1998 the  Company  acquired
proved oil and gas properties for $27.3 million and $2.1 million,  respectively.


                                      -12-


The  results  of  operations  include  these  acquisitions  and  the  subsequent
development of the properties. The Company purchased additional interests in its
properties  located  in the  Permian  Basin of New  Mexico and west Texas from a
variety of smaller owners. These purchases totaled $3.1 million and $1.2 million
in 1997 and 1998, respectively. In May 1997, the Company acquired an 85% working
interest in certain  Louisiana  properties of Henry Production  Company for $3.8
million. In November 1997, the Company acquired the interests of Conoco, Inc. in
the  Southwest  Mayfield area in Oklahoma for $20.6  million.  During the second
quarter of 1998, the Company entered into an exploration  and development  joint
venture in east Texas,  which included the  acquisition of interests in existing
properties for $510,000. The Company continues to seek acquisitions of producing
properties having significant  exploitation potential.  During the third quarter
of 1998 the Company entered into commitments for  approximately  $5.0 million of
acquisitions which are expected to close before year-end 1998.

In February  1997, the Company sold its interest in the Russian joint venture to
Khanty  Mansiysk Oil  Corporation  ("KMOC"),  formerly  known as Ural  Petroleum
Corporation, for $17.6 million. The Company received $5.6 million in cash before
transaction  costs,  $1.9  million  of  KMOC  common  stock  and  a  convertible
receivable  in a form  equivalent  to a  retained  production  payment  of $10.1
million plus interest at 10% per annum from the limited liability company formed
to hold the Russian joint venture  interest.  Uncertain  economic  conditions in
Russia and lower oil prices have affected the carrying value of the  convertible
receivable.  As a result the  Company has  reduced  the  carrying  amount of the
receivable  to its  minimum  conversion  value,  incurring  a pre-tax  charge to
operations of $4.6 million in the quarter ending September 30, 1998.

In February  1997,  the Company  closed the sale of  2,000,000  shares of common
stock at $25.00 per share and closed the sale of an additional 180,000 shares in
March 1997, pursuant to the underwriters' exercise of the over-allotment option.
These transactions resulted in aggregate net proceeds of $51.2 million.

In May 1997, the Company sold its non-operated interests in south Texas for $5.4
million  as part  of its  continuing  strategy  to  focus  and  rationalize  its
operations.

The Company  seeks to protect its rate of return on  acquisitions  of  producing
properties by hedging up to the first 24 months of an  acquisition's  production
at  prices  approximately  equal  to  those  used in the  Company's  acquisition
evaluation  and  pricing  model.  The Company  also  periodically  uses  hedging
contracts  to  hedge  or  otherwise  reduce  the  impact  of oil and  gas  price
fluctuations on production.  The Company's strategy is to ensure certain minimum
levels of  operating  cash flow and to take  advantage  of windows of  favorable
commodity  prices.  The Company generally limits its aggregate hedge position to
no more than 50% of its total  production.  The Company seeks to minimize  basis
risk and indexes the majority of its oil hedges to NYMEX prices and the majority
of its gas hedges to various regional index prices  associated with pipelines in
proximity  to the  Company's  areas of gas  production.  The  Company has hedged
approximately  2.5 million  MMBtu of its  remaining  1998 gas  production  at an
average fixed price of $2.19 per MMBtu.  The Company has also purchased  options
resulting in price  collars and price floors on 590,000  MMBtu of the  Company's
remaining  1998 gas production  with price ceilings  between $2.44 and $2.79 per
MMBtu and price floors between $2.00 and $2.20 per MMBtu. The Company has hedged
26,640 barrels of its remaining 1998 oil production at an average fixed price of
$15.57 per Bbl.

This  Quarterly  Report on Form 10-Q  includes  certain  statements  that may be
deemed to be  "forward-looking  statements" within the meaning of Section 27A of

Oil and Gas Production Revenues.  Oil and gas production revenues decreased $1.1
million,  or 6% to $16.6  million for the third  quarter 1998  compared to $17.7
million for the third quarter 1997. Oil production  volumes increased 5% and gas
production  volumes  increased 6% for the third  quarter 1998  compared to 1997.
Average  net  daily  production  reached  14.7 MBOE in the  third  quarter  1998
compared  to 13.8  MBOE in the  comparable  quarter  of  1997.  This  production
increase resulted from new properties acquired and drilled during the past year.
Major  acquisitions  included the Southwest Mayfield  properties  purchased from
Conoco, the acquisition of Louisiana  properties from Henry Production  Company,
and  the  additional   interests   purchased  in  the  Company's  Permian  Basin
properties.  Successful  drilling  results in the Box Church Field in Texas, the
South Horseshoe  Bayou and Haynesville  Fields in Louisiana and in the Company's
Oklahoma  drilling program also contributed to the third quarter 1998 production
increase.  The average  realized oil price for the third quarter 1998  decreased
34% to $11.97 per Bbl, and  realized  gas prices  decreased 2% to $2.07 per Mcf,
from their respective 1997 levels.

Oil and gas production  revenue  increased $1.9 million,  or 3% to $55.9 million
for the nine months ended  September 30, 1998 compared to $54.0 million in 1997.
Oil production  volumes  increased 16% and gas production  volumes increased 18%
for the first nine months of 1998  compared  with the  comparable  1997  period.
Average net daily  production was 15.8 MBOE for the nine months ended  September
30, 1998 compared to 13.5 MBOE in 1997. This production  increase  resulted from
new  properties  acquired  and  drilled  during  the past  year,  including  the
acquisition of the Southwest  Mayfield  properties in Oklahoma and the Louisiana
properties purchased from Henry Production Company.  Successful drilling results
in the Box Church  Field in Texas,  the South  Horseshoe  Bayou and  Haynesville
fields in Louisiana and the Company's  Oklahoma drilling program  contributed to
the 1998 production  increases.  The average oil price for the nine months ended
September 30, 1998 decreased 29% to $13.51 per barrel,  and gas prices decreased
4% to $2.14 per Mcf, from their respective 1997 levels.

The Company did not hedge any of its oil production  during the third quarter of
1998.  The Company  realized a $309,000  increase in oil revenue or $.31 per Bbl
for 1998 on earlier hedge contracts  compared to a $269,000 decrease or $.31 per
Bbl in 1997.  The Company  hedged  approximately  2.8 million MMBtu of its third
quarter  1998 gas  production  at an average  fixed price of $2.18 per MMBtu and
purchased  options  resulting in price collars and price floors on 620,000 MMBtu
of its third quarter 1998 gas production  with price ceilings  between $2.65 and
$2.80 per MMBtu and price floors between $1.95 and $2.00 per MMBtu.  The Company
realized a $999,000 increase in gas revenues or $.05 per Mcf for 1998 from hedge
contracts compared to a $1.5 million or $.09 per Mcf decrease in 1997.

Oil and Gas  Production  Costs.  Oil and gas  production  costs consist of lease
operating  expense,  workover costs and production taxes. Total production costs
increased  $523,000  or 13% for the  third  quarter  1998 from  comparable  1997
levels. Workover costs, including $331,000 for South Horseshoe Bayou, and higher
lease  operating  expenses were partially  offset by lower  production  taxes on
wells drilled in 1998 qualifying for reduced production tax rates. Total oil and
gas production costs per BOE increased 7% to $3.31 in 1998 compared to $3.10 per
BOE in the third quarter 1997.

Total  production  costs increased $1.5 million or 14% for the nine months ended
September  30, 1998 to $12.6  million due to increases  in workover  projects of
$847,000 and new properties  acquired and drilled during the past year. However,
total  production  costs per BOE  declined 3% to $2.91 for the nine months ended
September  30, 1998  compared to $3.00 for the nine months ended  September  30,
1997,  primarily due to lower lease operating  expenses per BOE from high volume
properties such as South Horseshoe Bayou.

Depreciation,  Depletion, Amortization and Impairment.  Depreciation,  depletion
and amortization expense ("DD&A") increased $1.6 million, or 39% to $5.6 million
in the third  quarter  1998  compared  with $4.0  million in 1997.  DD&A per BOE


                                      -15-


increased 31% to $4.17 in the third quarter 1998 compared to $3.17 in 1997. This
increase resulted from increased  production volumes of new properties  acquired
and drilled with a higher cost basis since the last  quarter of 1997,  increased
water production at South Horseshoe Bayou adversely affecting reserve quantities
and the adverse  impact of low oil prices in the  Williston  Basin.  The Company
recorded  impairments  of proved oil and gas  properties  of $6.8 million in the
third quarter 1998 compared with $288,000 in the comparable  1997 period.  These
third  quarter 1998 charges  resulted  from one high cost  marginal well each in
Oklahoma and Louisiana,  one development dry hole in Oklahoma and a $6.2 million
charge associated with the unsuccessful  deep test at the Company's  Atchafalaya
prospect in south Louisiana.

DD&A increased 45% to $17.5 million for the nine months ended September 30, 1998
compared  with $12.1  million in 1997 because of increased  production,  reserve
declines from low oil prices and water  production at South Horseshoe Bayou, and
higher cost  properties  in four fields in Oklahoma.  DD&A per BOE  increased to
$4.06 in the nine months  ended  September  30, 1998  compared to $3.28 in 1997.
Impairment  of producing  oil and gas  properties  was $8.2 million for the nine
months ended  September  30, 1998 compared to $804,000 for the nine months ended
September 30, 1997, due to the unsuccessful  deep test at Atchafalaya,  marginal
and unsuccessful  development wells drilled in Oklahoma, Texas and Louisiana and
the adverse effects of low oil prices in the Williston Basin.

Abandonment and impairment of unproved properties increased $1.1 million to $2.5
million  in the third  quarter  1998  compared  to $1.4  million  in 1997.  This
increase was primarily due to a $1.9 million impairment of the carrying value of
the undeveloped acreage in the Atchafalaya prospect.

Abandonment and impairment of unproved properties increased $1.2 million to $3.1
million in the nine months ended  September 30, 1998 compared to $1.8 million in
the comparable period in 1997, primarily due to impairment of Atchafalaya in the
third quarter of 1998.

Exploration.  Exploration expense increased $1.9 million or 196% to $2.9 million
for the third quarter 1998 compared with $989,000 in 1997  primarily as a result
of three unsuccessful exploratory wells drilled in Oklahoma.

Exploration  expense increased $5.4 million or 135% to $9.4 million for the nine
months ended  September 30, 1998 compared to $4.0 million in 1997. This increase
is due to the drilling of nine unsuccessful exploratory tests in south Louisiana
and  Oklahoma  and the payment of $795,000  for delay  rentals in the  Company's
Atchafalaya prospect area during 1998.

General  and  Administrative.   General  and  administrative  expenses  declined
$235,000 or 16% to $1.2 million for the third  quarter 1998 as compared to 1997.
Increased  compensation  and rent expenses were offset by declines in charitable
contributions and increased overhead reimbursements from outside interest owners
in Company operated properties.

General and administrative expenses decreased $380,000 or 6% to $5.7 million for
the nine  months  ended  September  30, 1998  compared to $6.0  million in 1997.
Increased  compensation  and rent expenses were offset by declines in charitable
contributions,  insurance  and  general  corporate  expenses  and  increases  in
overhead  reimbursements  from outside interest owners in properties operated by
the Company.

Other  operating  expenses  consist of legal expenses in connection with ongoing
oil and gas activities and oversight of the Company's mining  investments.  This
expense decreased $56,000 to $13,000 in the third quarter 1998 compared with the
third quarter 1997.

Other  operating  expenses  remained  unchanged  at $105,000  for the first nine
months of 1998 compared to the comparable 1997 period.



                                      -16-


Equity in  Income of  Russian  Joint  Venture.  The  Company  accounted  for its
investment in the Russian joint venture under the equity method and included its
share of income from the venture in its results of operations up to the point of
sale.  Therefore  no equity in the net income of the Russian  joint  venture was
recorded in 1998  compared to $203,000  recorded  in 1997.  As  discussed  under
Outlook,  the Company  sold this  investment  in February  1997  resulting  in a
partial year of equity income recorded in 1997.

Equity in Loss of Summo  Minerals  Corporation.  The  Company  accounts  for its
investment  in Summo under the equity  method and  includes its share of Summo's
income or loss in its results of  operations.  The  Company's  equity in the net
loss of Summo was $41,000 in the third quarter 1998 and $275,000 in 1997.

The  Company's  equity in the net loss of Summo was $612,000 for the nine months
ended September 30, 1998 compared to $297,000 in 1997,  primarily due to Summo's
decision to write-off its  investment  in its Cashin and Champion  properties in
the second quarter 1998.

Non-Operating  Income and Expense.  Interest income decreased $319,000 or 86% to
$50,000 for the third  quarter 1998 from $369,000 for the third quarter 1997 due
to the use of available  cash for debt  reduction.  Interest  expense  increased
$241,000 or 180% to $375,000 for the third  quarter 1998 compared to $134,000 in
the 1997 period due to increased  borrowings under the Company's credit facility
in 1998.  Debt under the Company's  credit facility had been repaid in the first
quarter 1997 with the proceeds  from the sale of the  Company's  common stock in
February 1997.

Interest income decreased  $260,000 or 31% to $576,000 in the nine-month  period
ended  September 30, 1998 compared to $836,000 for the  comparable  1997 period.
This decrease was due to the Company's use of available cash for debt reduction,
partially  offset by $312,000 of interest  income from a favorable gas balancing
decision by the Oklahoma  Supreme Court in the second quarter of 1998.  Interest
was earned in the nine-month  period ended September 30, 1997 on funds available
from the sale of the  Company's  common  stock.  Interest  expense  for the nine
months  ended  September  30, 1998  increased  $270,000  or 31% to $1.1  million
compared to  $859,000  for 1997 due to  borrowings  under the  Company's  credit
facility during 1998.

Income Taxes. The Company had an income tax benefit of $4.0 million in the third
quarter 1998  compared to income tax expense of $2.2 million in 1997,  resulting
in effective  tax rates of 34% and 35.4%,  respectively.  This  reduced  expense
reflects  lower net income from  operations  before income taxes for 1998 due to
lower oil and gas prices,  increased  exploration  and DD&A expenses,  increased
impairment of producing  properties  and the write-down of the carrying value of
the Russian convertible receivable.

Income tax expense decreased $13.8 million resulting in an income tax benefit of
$2.1  million  for the nine months  ended  September  30,  1998.  This  decrease
primarily resulted from lower oil and gas prices,  increased exploration expense
and  DD&A  expenses,  increased  impairment  of  producing  properties  and  the
write-down of the carrying value of the Russian convertible  receivable in 1998.
The reduction of income tax expense for the nine months ended September 30, 1998
compared to 1997 was also the result of the $9.7 million and $4.2 million  gains
on the sales of the Company's  Russian  joint  venture and non-core  properties,
respectively,  in  1997.  The  effective  tax rate  for the  nine  months  ended
September 30, 1998 decreased to 34.2% compared to 35.5% in the 1997 period.

Net Income.  Net income for the third  quarter 1998  decreased  $11.8 million or
290% to a net loss of $7.7  million  compared  to net income of $4.1  million in
1997. Increases of 5% and 6% in oil and gas volumes, respectively, offset by 34%
and 2% decreases in oil and gas prices, respectfully, resulted in a $1.0 million
decrease  in oil  and  gas  production  revenues  for the  third  quarter  1998.
Increases of $1.6 million, $6.5 million and $1.1 million in DD&A, impairments of
producing  properties and impairments of unproved  properties,  respectively and
the $4.6 million write-down of the Russian  convertible  receivable,  which were
partially  offset by an income tax benefit of $4.0 million,  also contributed to
the decrease in net income for the third quarter 1998.

Net income for the nine months ended  September 30, 1998 decreased $25.5 million
to a net loss of $4.0 million  compared to net income of $21.5  million in 1997.
This decrease  resulted from increased oil and gas  production,  offset by lower
oil and gas prices and increases in exploration  expense,  DD&A,  impairments of
producing properties and the write-down of the Russian convertible receivable in


                                      -17-


1998. Also  contributing to the decrease in net income was the $9.7 million gain
on the sale of the Company's  interest in the Russian joint venture and the $4.2
million gain on the sale of the  Company's  non-core  south Texas  properties in
1997.

Liquidity and Capital Resources

The  Company's  primary  sources of liquidity are the cash provided by operating
activities, debt financing and access to the capital markets. The Company's cash
needs  are for  the  acquisition,  exploration  and  development  of oil and gas
properties and for the payment of debt obligations,  trade payables, stockholder
dividends  and for the  repurchase of the  Company's  common stock.  The Company
generally  finances its  exploration  and  development  programs from internally
generated  cash  flow,  bank  debt and cash and cash  equivalents  on hand.  The
Company  continually  reviews its capital expenditure budget based on changes in
cash flow and other factors.

Cash Flow.  The Company's net cash  provided by operating  activities  increased
$2.2 million or 7% to $36.5 million in the nine months ended  September 30, 1998
compared to $34.2 million in 1997.  Increased  receipts for oil and gas revenues
due to higher  production  volumes,  despite  reduced oil and gas  prices,  were
offset by increased  payments  for lease  operating  expenses and  significantly
higher payments related to exploration expenses.  Also, in the first nine months
of 1997 the  Company  made a cash  payment  of  approximately  $1.6  million  in
satisfaction  of  liabilities  previously  accrued  by  the  Company  under  its
discontinued  SAR plan  compared to a  corresponding  payment of $363,000 in the
first nine months of 1998.

Net cash used in investing  activities  in the nine months ended  September  30,
1998 increased  $13.4 million or 41% to $46.5 million  compared to $33.1 million
in 1997.  This increase was primarily due to a $5.0 million  increase in capital
expenditures  for the  Company's  drilling  programs  in 1998,  offset by a $5.4
million  decrease in  acquisition  expenditures  in 1998,  $5.6  million in cash
received  from the sale of the  Company's  Russian  joint  venture  in the first
quarter  1997 and $7.5  million  received  in 1997  from the sale of oil and gas
properties.  Total  capital  expenditures  in the  first  nine  months  of 1998,
including acquisitions of oil and gas properties, were $45.4 million compared to
$45.8 million in 1997.

The Company  applied the majority of the proceeds  from the sales of oil and gas
properties in 1997 to  acquisitions  of oil and gas  properties in 1997 allowing
tax-free  exchanges of these  properties for income tax purposes.  In a tax-free
exchange of properties  the tax basis of the sold  property  carries over to the
new property. Gains or losses for tax purposes are recognized by amortization of
the tax basis of the new property  throughout its remaining life or when the new
property is sold or abandoned.

Net cash  provided by  financing  activities  was $6.1 million in the nine month
period ended  September 30, 1998  resulting from net borrowing of long-term debt
of $10.0 million, offset by expenditures of $2.5 million to repurchase shares of
the Company's  common  stock,  and payments of dividends to  shareholders.  This
compares to net cash  provided by financing  activities  of $14.0 million in the
comparable  1997 period.  The Company  received  $51.2  million from the sale of
common stock and had a net reduction of borrowings of $35.7 million in the first
quarter of 1997.  The Company  increased its quarterly  dividend 25% to $.05 per
share effective with the quarterly dividend declared in January 1997 and paid in
February 1997.



                                      -18-


The Company had $3.1 million in cash and cash equivalents and working capital of
$5.0 million as of September  30, 1998 compared to $7.1 million of cash and cash
equivalents  and working  capital of $9.6  million at  December  31,  1997.  The
reduction in cash and cash  equivalents  is primarily the result of payments for
capital expenditures,  property  acquisitions and exploration  expenses,  and to
reduce debt levels.  Working capital  decreased due to the reduction in cash and
cash equivalents and decreased  accounts  receivable,  primarily for oil and gas
sales due to price declines,  offset by a smaller  decrease in accounts  payable
and accrued expenses resulting from drilling activity.

Credit  Facility.  On June 30, 1998,  the Company  entered into a new  long-term
revolving credit agreement replacing its credit facility dated March 1, 1993 and
amended April 1, 1996. The new credit facility provides a maximum loan amount of
$200.0  million.  The amount that may be borrowed  from time to time will depend
upon the value of the Company's  oil and gas  properties  and other assets.  The
Company's  borrowing base,  which is redetermined  annually,  was increased from
$40.0  million to $60.0  million in February  1997 and further  increased in May
1998 to $115.0 million based on increases in the Company's  estimated net proved
reserves in 1996 and 1997. The initial accepted borrowing base is $40.0 million.
The  maturity  date of the new credit  agreement  is December  31,  2005,  which
includes a revolving period maturing on December 31, 2000. The Company may elect
to allocate up to 50% of the available borrowings to a short-term tranche due in
364  days.  Outstanding  revolving  loan  balances  under the  Company's  credit
facility,  which were $25.2  million and $14.5 million at September 30, 1998 and
December 31, 1997,  respectively,  accrue  interest at rates  determined  by the
Company's debt to total capitalization ratio. During the revolving period of the
loan, loan balances  accrue  interest at the Company's  option of either (a) the
higher of the banks' prime rate or the Federal Funds Rate plus 1/2% or (b) LIBOR
plus 1/2% when the Company's debt to total  capitalization  is less than 30%, up
to a maximum  of the  Company's  option of either  (a) the  higher of the banks'
prime  rate  plus 1/8% or the  Federal  Funds  Rate plus 5/8% or (b) LIBOR  plus
1-1/4%  when the  Company's  debt to total  capitalization  ratio is equal to or
exceeds 50%. The credit  facility  provides for,  among other things,  covenants
requiring maintenance of stockholders' equity at a specified level and limits on
additional indebtedness of the Company.

Panterra, in which the Company has a 74% general partnership ownership interest,
has a separate credit facility with a $25.0 million borrowing base as of July 1,
1998,  and $10.0 million and $11.0 million  outstanding as of September 30, 1998
and December 31, 1997, respectively.  In September 1997, Panterra entered into a
credit agreement replacing a previous  agreement,  which was due March 31, 1999.
The new credit agreement  includes a two-year  revolving period  converting to a
five-year  amortizing loan on June 30, 1999.  During the revolving period of the
loan, loan balances  accrue  interest at Panterra's  option of either the bank's
prime rate or LIBOR plus 3/4% when the  Partnership's  debt to partners' capital
ratio is less than 30%, up to a maximum of either the bank's prime rate or LIBOR
plus 1-1/4% when the  Partnership's  debt to partners'  capital ratio is greater
than 100%.  The Company  intends to use the available  credit under the Panterra
credit facility to fund its 1998 capital expenditures in the Williston Basin.

Common Stock. In February 1997, the Company closed the sale of 2,000,000  shares
of common stock at $25.00 per share and closed the sale of an additional 180,000
shares  in  March  1997,   pursuant  to  the   underwriters'   exercise  of  the
over-allotment  option. These transactions resulted in aggregate net proceeds of
$51.2  million.  The  proceeds  of these  sales were used to fund the  Company's
exploration,  development  and acquisition  programs,  and pending such use were
used to repay borrowings under its credit facility.

In June 1998, the Company's  shareholders  approved an increase in the number of
authorized  shares of the  Company's  common stock from 15 million to 50 million
shares.

In August 1998, the Company's Board of Directors  authorized a stock  repurchase
program  whereby the  Company may  purchase  from  time-to-time,  in open market


                                      -19-


purchases or negotiated sales, up to one million shares of its common stock. The
Company has repurchased 147,800 shares of its common stock under the program for
$2.5  million,  a  weighted-average  price  of  $16.71  per  share.   Management
anticipates  that  additional  purchases  of shares by the  Company may occur as
market conditions warrant. Such purchases will be funded with internal cash flow
and borrowings under the Company's credit facility.

Outlook.  The Company  believes that its existing capital  resources,  cash flow
from operations and available  borrowings are sufficient to meet its anticipated
capital and operating requirements for 1998.

The Company allocates approximately 85% of its capital budget to low to moderate
risk  exploration,  development and  acquisition  programs in its core operating
areas.  The  remaining  approximately  15% of the  Company's  capital  budget is
directed to higher  risk,  large  exploration  ideas that have the  potential to
increase the Company's reserves by 25% or more in any single year.

The Company has reduced its 1998 capital budget by  approximately  $16.5 million
to a revised total of  approximately  $77.5  million.  The reduction  reflects a
reallocation of capital to the Company's stock  repurchase  program as well as a
response to lower oil prices and drilling  results.  Reductions  of $2.1 million
arise from postponement of new drilling activities in the Williston Basin due to
low oil prices;  $5.5 million due to the cancellation of a previously  scheduled
second deep test at the Company's Atchafalaya prospect and from the postponement
of the large target Patterson  prospect in south Louisiana to 1999; $4.9 million
due to suspension or postponement  of capital  projects in the Permian Basin and
$4.0 million from  re-balancing of the drilling program in the Anadarko Basin to
emphasize  less  costly and lower risk  prospects.  The revised  capital  budget
includes an allocation of $20.0  million for property  acquisitions  in 1998, of
which approximately $2.1 million has been incurred through September 30, 1998.

The amount and allocation of future capital and  exploration  expenditures  will
depend upon a number of factors  including  the number of available  acquisition
opportunities, the Company's ability to assimilate such acquisitions, the impact
of oil and gas prices on investment  opportunities,  the availability of capital
and the success of its development and exploratory  activity which could lead to
funding requirements for further development.

The Company continuously evaluates  opportunities in the marketplace for oil and
gas  properties  and,  accordingly,  may be a buyer or a seller of properties at
various times. In October 1998, the Company assembled a package of non-strategic
properties  for sale  consisting  of wells in eight fields in the  Mid-Continent
region.  Completion  of the  sale of  these  properties  is  anticipated  before
year-end  1998.  The proceeds from this  transaction  will be used to reduce the
Company's  outstanding bank debt in anticipation of re-deploying this capital in
the Company's drilling, exploration and acquisition programs in 1999.

The  Company  has  added  several  prospects  to its  pipeline  of large  target
exploration ideas and expects to commence the drilling of four significant tests
in early 1999 at its Stallion,  South  Horseshoe  Bayou and Edgerly  projects in
south Louisiana and its Carrier project in east Texas.

Volatile industry  conditions and several exploration  disappointments  early in
the year are  combining  to make 1998 a  particularly  challenging  year for the
Company as it consolidates the rapid growth in reserves and production  achieved
during the past several years.  Production  volumes,  other than South Horseshoe
Bayou,  are expected to remain at levels  comparable to the third quarter during
the balance of the year.

The St. Mary Land & Exploration No. 3 (40 percent net revenue interest) at South
Horseshoe  Bayou was  completed  in  January  1998 in the  17,300-foot  sand and
experienced  increasing  water  production  beginning in early June. Into August
1998 the well continued to produce  approximately 34 MMCF of gas and 200 barrels
of condensate per day. In August 1998, the well encountered  mechanical problems


                                      -20-


resulting  in the need to suspend  production  pending a  recommendation  by the
operator  regarding a procedure to return the well to  production  or to abandon
it. The net proved reserves  assigned to the 17,300-foot  sand in the No. 3 well
at year-end  1997 were 33.1 BCF of gas and 177,000  barrels of  condensate.  The
Company anticipates that a portion of the proven reserves  attributable to South
Horseshoe Bayou may be reduced or  reclassified.  The magnitude of any potential
reserve  adjustments at South Horseshoe Bayou will not be known until early 1999
following  completion of the annual  review of the  Company's  reserves by Ryder
Scott and Company.

The  Company's  Atchafalaya  discovery  began  production  in August  1998,  but
production  testing indicated a limited reservoir.  The Company  recompleted the
well in an upper zone in November 1998.

In May 1997, the Company  entered into an agreement to receive a 55% interest in
Summo's Lisbon Valley Copper  Project (the  "Project") in return for the Company
contributing  $4.0 million in cash, all of its outstanding  stock in Summo,  and
$8.6 million in letters of credit for development of the Project.  The agreement
is subject to certain conditions,  including project financing.  The Company has
agreed to provide  interim  financing of up to $2.95  million for the Project in
the form of a loan to Summo due in June 1999.  As of September  30,  1998,  $2.8
million was  outstanding  under this loan.  Any principal  and interest  amounts
outstanding  are  convertible  into shares of Summo  common stock any time after
December  31,  1998 at the option of the  Company.  Upon  capitalization  of the
Project,  the outstanding loan principal shall constitute a capital contribution
in partial  satisfaction of the Company's capital commitments set out in the May
1997 agreement.  In September 1998, Summo received final regulatory  approval to
develop the Project. Future development and financial success of the Project are
largely  dependent on the market price of copper,  which is  determined in world
markets and is subject to significant  fluctuations.  Current copper prices have
declined to ten-year lows and do not justify construction and development of the
Project at this time.  However,  Management  believes  that  copper  prices will
recover when international  economic conditions improve. The Company has entered
into agreements to provide interim  financing to the Project through the balance
of 1998 and will evaluate the Project's  future  funding  requirements  in early
1999.  There can be no  assurance  that the Company will realize a return on its
investment in Summo or the Project.

In February  1997,  the  Company  sold its Russian  joint  venture to KMOC.  The
Company  received  approximately  $5.6  million  in  cash  consideration  before
transaction  costs, KMOC common stock valued at approximately $1.9 million and a
receivable  in  a  form   equivalent  to  a  retained   production   payment  of
approximately  $10.1  million  plus  interest  at 10% per annum from the limited
liability  company  formed  to hold the  Russian  joint  venture  interest.  The
Company's  receivable is  collateralized  by the partnership  interest sold. The
Company  has the  right,  subject  to certain  conditions,  to  require  KMOC to
purchase the  Company's  receivable  from the net proceeds of an initial  public
offering of KMOC common stock or alternatively, the Company may elect to convert
all or a portion of its receivable into KMOC common stock  immediately  prior to
an initial public offering of KMOC common stock.  Uncertain economic  conditions
in  Russia  and  lower  oil  prices  have  affected  the  carrying  value of the
convertible receivable.  As a result the Company has reduced the carrying amount
of the  receivable  to its  minimum  conversion  value,  incurring  a charge  to
operations of $4.6 million in the quarter ending September 30, 1998.

Impact of the Year 2000  Issue.  The Year 2000 Issue is the  result of  computer
programs and embedded  computer  chips being written or  manufactured  using two
digits  rather  than four,  or other  methods,  to define the  applicable  year.
Computer  programs and embedded  chips that are  date-sensitive  may recognize a
date using "00" as the year 1900 rather than the year 2000. This could result in
a  system  failure  or  miscalculations   causing   disruptions  of  operations,
including,  among other things, a temporary  inability to process  transactions,
operate equipment or engage in normal business activities.  Failure to correct a
material Year 2000  compliance  problem could result in an  interruption  in, or
inability to conduct normal  business  activities or  operations.  Such failures
could materially and adversely affect the Company's results of operations,  cash
flow and financial condition.



                                      -21-


The Company's  approach to determining  and mitigating the impact on the Company
of Year 2000  compliance  issues is  comprised  of five  phases:  i) review  and
assessment of all internal  information  technology (IT) systems and significant
non-IT systems for Year 2000  compliance;  ii) identify and  prioritize  systems
with Year 2000 compliance issues;  iii) repair or replace and test non-Year 2000
compliant  systems;  iv)  survey  and  assess  the Year  2000  readiness  of the
Company's significant vendors,  suppliers and purchasers and transporters of oil
and natural gas; v) design and implement contingency plans for those systems, if
any, that cannot be made Year 2000 compliant before December 31, 1999.

The Company has substantially completed phases i) and ii) and has identified the
systems  that must be repaired  or replaced in order to be Year 2000  compliant.
The Company  determined  that,  of its major  systems,  the software it uses for
reservoir  engineering,  its  telephone  system,  a  significant  number  of the
personal  computers  used by Company  personnel and the computer  system used by
Panterra  must be  updated  or  replaced.  The  telephone  system  and  personal
computers have been replaced with Year 2000 compliant hardware and software. The
Company  anticipates a Year 2000 compliant release of the reservoir  engineering
system in the  fourth  quarter  of 1998 with  implementation  and  testing to be
completed by June 30, 1999.  Panterra has licensed a Year 2000 compliant  system
and is in the  process  of  converting  to the new  system.  The  conversion  is
anticipated to be completed,  tested and operational during the first quarter of
1999. The Company presently believes that other less significant  systems can be
upgraded  to  mitigate  any Year 2000  issues  with  modifications  to  existing
software or  conversions  to new software.  Modifications  or conversions to new
software for the less significant  systems, if not completed timely,  would have
neither a material impact on the operations of the Company nor on its results of
operations.

The cost to remediate the Company's  known Year 2000  compliance  issues through
repair or replacement and testing of non-compliant systems is not anticipated to
have a material affect on the Company's results of operations.

The Company has initiated formal  communications  with its significant  vendors,
suppliers and  purchasers and  transporters  of oil and natural gas to determine
the extent to which the Company is vulnerable to those third  parties'  failures
to remediate their own Year 2000 issues.  The process of collecting  information
from these third parties is not complete, therefore, management cannot currently
predict if third party  compliance  issues will materially  affect the Company's
operations.  There can be no assurance  that the systems of these third  parties
will be converted  timely,  or that a failure to remediate Year 2000  compliance
issues by  another  company  would  not have a  material  adverse  affect on the
Company.

Accounting Matters

In February  1997, the Financial  Accounting  Standards  Board  ("FASB")  issued
Statement of Financial  Accounting  Standards  ("SFAS") No. 128,  "Earnings  Per
Share," which  requires a dual  presentation  of basic and diluted  earnings per
share. The Company adopted SFAS No. 128 effective  December 31, 1997. Under SFAS
No. 128 basic net income per share of common stock is calculated by dividing net
income by the weighted  average of common shares  outstanding  during each year,
and  diluted  net income  per  common  share of common  stock is  calculated  by
dividing net income by the weighted  average of common shares and other dilutive
securities.

In  September  1997,  the FASB  issued SFAS No.  130,  "Reporting  Comprehensive
Income,"  effective for financial  statements for fiscal years  beginning  after
December 15, 1997. The Statement establishes standards for reporting and display
of comprehensive income and its components in financial statements. The adoption
of this  statement  will not have a material  impact on the Company's  financial
statements.



                                      -22-


In September 1997, the FASB issued SFAS No. 131,  "Disclosures about Segments of
an Enterprise and Related  Information,"  effective for financial statements for
fiscal years beginning after December 15, 1997. The Statement requires companies
to report  certain  information  about  operating  segments  in their  financial
statements  and certain  information  about their  products  and  services,  the
geographic areas in which they operate and their major customers. The Company is
currently reviewing the effects of the disclosure requirements of the Statement.

In February 1998, The FASB issued SFAS No. 132,  "Employer's  Disclosures  about
Pensions  and  Other  Postretirement   Benefits,"  effective  for  fiscal  years
beginning  after  December 15, 1997. The Statement  standardizes  the disclosure
requirements  for  pensions  and  other   postretirement   benefits  to  provide
information  that is more  comparable  and  concise.  The  Company is  currently
reviewing the effects of the disclosure requirements of the Statement.

In September  1998,  the FASB issued SFAS No. 133,  "Accounting  for  Derivative
Instruments and Hedging Activities," effective for all fiscal quarters of fiscal
years  beginning after June 15, 1999. The Statement  establishes  accounting and
reporting  standards for derivative  instruments,  including certain  derivative
instruments embedded in other contracts, and for hedging activities. The Company
is currently  reviewing  the effects this  Statement  will have on the financial
statements in relation to the Company's hedging activities.

Effects of Inflation and Changing Prices

The Company's  results of operations  and cash flow are affected by changing oil
and gas prices.  Within the United States  inflation has had a minimal effect on
the Company.  The Company cannot  predict the extent of any such effect.  If oil
and gas prices increase,  there could be a corresponding increase in the cost to
the Company for drilling and related services, although offset by an increase in
revenues.  Should  oil and gas  prices  increase,  the cost of  acquisitions  of
producing  properties will increase,  which could limit the Company's ability to
acquire properties that meet the Company's criteria.

During the first half of 1998 the Company experienced an increase in the cost to
the Company for  drilling  and related  services  resulting  from  shortages  in
available  drilling  rigs,  drilling  and  technical  personnel,   supplies  and
services.  However,  since  mid-year  service costs have  stabilized or begun to
decline. If shortages persist, there could be continued increases in the cost to
the Company of exploration, drilling and production of oil and gas.
