directors and recorded compensation expense of $68,175.

In June 1997, an officer of the Company  exercised  14,072 options to buy common
stock at $20.50 per share.  As payment of the exercise  price and taxes due, the
Company  accepted  11,022 of the exercised  shares,  resulting in an increase in
shares outstanding of 3,050.

Note 2 - Investments

In March 1996, the Company  completed its purchase of the remaining stock of St.
Mary Operating Company ("SMOC").  The purchase increased the Company's ownership
in SMOC from 65% to 100%.  Through March 31, 1996 the Company  accounted for its
investment in SMOC using the equity method of accounting.

The Company,  through subsidiaries,  owned an 18% interest in a venture which is
developing the  Chernogorskoye  oil field in western Siberia (the "Russian joint
venture"). The Company accounted for its investment in the Russian joint venture
using 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 recorded a gain on the sale of
the Russian joint venture interest of $9,671,000. The Company recorded income of
$201,000 in 1997 as its equity in income from the Russian  joint venture for the
period prior to the sale.

The  Company  accounts  for  its  37%  ownership   interest  in  Summo  Minerals
Corporation ("Summo") using the equity method of accounting. For the nine months
ended September 30, 1997, the Company  recorded a loss of $498,000 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  final  resolution of  regulatory  approvals and
project  financing.  Summo is  currently  conducting  tests of the ground  water
quality to address  concerns  raised on appeal  during the  permitting  process.
These tests are  anticipated to be completed by year-end. The Company has agreed
to provide interim  financing of up to $2,225,000 for the Project in the form of
a loan to Summo due in June 1999.  As of  September  30,  1997,  $1,332,000  was
outstanding  under this loan.  Additional  amounts  totaling  $537,000 have been
advanced to Summo under this loan since  September  30, 1997.  Any principal and
interest  amounts  outstanding are convertible into shares of Summo common stock
anytime   after   December  31,  1997  at  the  option  of  the  Company.   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.

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
$51.2  million.  The  proceeds  were  used to fund  the  Company's  exploration,
development and acquisition  programs and to repay  borrowings  under its credit
facility.

Note 4 - Recently Issued Accounting Standards

In June 1997, the FASB issued SFAS No. 130,  "Reporting  Comprehensive  Income,"
effective for financial  statements  for periods  beginning  after  December 15,
1997.  The  Statement   establishes  standards  for  reporting  and  display  of
comprehensive income and its components in financial  statements.  Comprehensive
income for the Company will be affected by changes in unrealized gains or losses
on marketable equity securities.

In February  1997, the Financial  Accounting  Standards  Board  ("FASB")  issued
Statement of Financial  Accounting  Standards  ("SFAS") No. 129,  "Disclosure of
Information  about Capital  Structure,"  effective for financial  statements for
periods ending after December 15, 1997. The Statement requires disclosures about
certain preferences and rights of outstanding securities and certain information
about redeemable  capital stock. At this time the Company has no preferential or
redeemable securities that will be subject to the new disclosure requirements of
the Statement.

Note 5 - Earnings per Share

In February 1997, the FASB issued SFAS No. 128,  "Earnings Per Share," effective
for  financial  reports  issued  subsequent  to December 15, 1997.  SFAS No. 128
replaces the calculation of Primary Earnings per Share with a calculation called
Basic  Earnings per Share and replaces  Fully Diluted  Earnings per Share with a
calculation called Diluted Earnings per Share.

The  following  table  shows the impact  that  adoption  of SFAS No.  128, as of
January 1, 1996, would have had on the Company's reported earnings per share.

Note 6 - Income Taxes

Federal  income tax expense for 1997 and 1996 differs from the amount that would
be provided by applying the  statutory  U.S.  Federal  income tax rate to income
before  income taxes  primarily  due to state income taxes  partially  offset by
Section 29 tax credits and  percentage  depletion  in 1997 and wholly  offset by
these items in 1996.

Note 7 - Subsequent Events

In November 1997, the Company completed the acquisition of producing  properties
in the SW Mayfield  Field of Beckham  County  Oklahoma  for $20.3  million.  The
acquisition  was funded  with cash on hand and  borrowings  under the  Company's
credit facility.

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

Overview

     St. Mary was founded in 1908 and  incorporated  in Delaware in 1915.  Since
1992 St. Mary has expanded its technical  and operating  staff and increased its
drilling, production and operating capabilities in its five core operating areas
in the United States.

     The  Company's  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.

     The  Company  has  two  principal   equity   investments,   Summo  Minerals
Corporation  ("Summo"),  a Canadian copper mining company,  and, until recently,
its Russian joint  venture.  The Company  accounts for its Russian joint venture
and  investment  in Summo under the equity  method and includes its share of the
income or loss from these  entities.  Effective  February 12, 1997,  the Company
sold its Russian joint venture.

     Included in the 1997  results are the  operations  of several  acquisitions
made during the past few years.  In December  1995,  the  Company  acquired  two
different  interests  in the Box  Church  Field  located  in east Texas for $2.2
million  and  several  additional  interests  in 1996 for  $580,000.  Subsequent
drilling in this field proved the upside  potential  the Company had  identified
and added 26.4 billion  cubic feet of net gas reserves at December 31, 1996.  In
June 1996,  the Company  acquired a 90% interest in certain  assets of Siete Oil
and Gas  Corporation in the Permian Basin of west Texas and southeast New Mexico
for $10.0 million and thereafter completed a series of follow-on acquisitions of
other interests in the Siete properties  totaling $5.5 million. In October 1996,
the Company acquired additional  interests from Sonat Exploration Company in its
Elk  City  Field  located  in  Oklahoma  for  $5.7  million.   Several   smaller
acquisitions were also completed during 1996 totaling $2.8 million. In May 1997,
the Company  acquired  its first  operated  interests  in  Louisiana  from Henry
Production Company for $3.9 million.

     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
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.

     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.

     In November  1997,  the Company  completed  the  acquisition  of a group of
producing properties in Oklahoma for $20.3 million.


                                      -10-


     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 or greater than 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  from each of its core  operating
areas.  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 27% of
its estimated  1997 gas  production at an average fixed price of $2.08 per MMBtu
and  approximately  15% of its estimated 1997 oil production at an average fixed
price of $18.36 per Bbl.  The Company has also  purchased  options  resulting in
price collars and price floors on approximately  30% of the Company's  estimated
1997 oil production  with price  ceilings  between $21.00 and $27.00 per Bbl and
price floors between $18.00 and $21.00 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

statements.  These statements are based on certain assumptions and analyses made
by the  Company in light of its  experience  and its  perception  of  historical
trends,  current  conditions,  expected future developments and other factors it

     Oil and Gas Production  Revenues.  Oil and gas production revenue increased
$2.7  million,  or 18% to $17.7  million for the third  quarter 1997 compared to
$14.9 million in 1996. Oil production volumes decreased 11% while gas production
volumes  increased  42% for the third  quarter 1997 compared to the 1996 period.
Average net daily  production was 13,821 BOE for the third quarter 1997 compared
to 11,018 BOE in 1996.  The  production  increase  resulted from new  properties
acquired and drilled  during the past year.  The average oil price for the third
quarter 1997  decreased 6% to $18.13 per barrel,  while the average gas price of
$2.11 per Mcf was unchanged from respective 1996 levels.


                                      -12-


     Oil and gas production  revenue  increased  $14.3 million,  or 36% to $54.0
million for the nine months ended  September  30, 1997 compared to $39.7 million
in 1996.  Oil  production  volumes  decreased  1% while gas  production  volumes
increased 50% for the first nine months of 1997 from the comparable 1996 period.
Average net daily  production was 13,469 BOE for the nine months ended September
30, 1997 compared to 9,998 BOE in 1996. This production  increase  resulted from
new properties  acquired and drilled during the past year. The average oil price
for the nine months ended  September 30, 1997 increased 5% to $19.16 per barrel,
while gas  prices  increased  5% to $2.22 per Mcf,  from their  respective  1996
levels.

     The  Company  has  hedged  approximately  12% of  its  remaining  1997  oil
production at an average price of $18.51 per barrel and an additional 14% of its
remaining  1997 oil  production  through price collars with floors of $18.00 and
ceilings of $22.00 per barrel.  The Company realized a $269,000  decrease in oil
revenue  or $.31 per  barrel  for the  first  nine  months  of 1997 on oil hedge
contracts  compared  to an  $846,000  decrease  or $.98 per barrel in 1996.  The
Company has also hedged  approximately  27% of its remaining 1997 gas production
at an average  price of $2.15 per MMBtu.  The  Company  realized a $1.5  million
decrease in gas revenue or $.09 per MMBtu for the first nine months of 1997 from
gas hedge contracts compared to a $647,000 or $.06 per MMBtu decrease in 1996.

     Oil and Gas Production Costs. Oil and gas production costs consist of lease
operating  expense  and  production  taxes.  Total  production  costs  increased
$605,000,  or 18% to $3.9  million in the third  quarter  1997  compared to $3.3
million in 1996 as a result of new  properties  acquired and drilled  during the
past year. However, total production costs per BOE decreased 6% to $3.10 for the
third  quarter  1997  compared  with  $3.29  for  1996,  primarily  due to state
production  tax  incentive  programs  and low lease  operating  expenses per BOE
associated with the South Horseshoe Bayou production added in 1997.

     Total  production  costs  increased $1.8 million or 19% for the nine months
ended September 30, 1997 to $11.0 million as a result of new properties acquired
and  drilled  during  the past year.  However,  total  production  costs per BOE
declined 11% to $3.00 for the nine months ended  September  30, 1997 compared to
$3.38 for the nine months  ended  September  30,  1996,  primarily  due to state
production  tax  incentive  programs  and low lease  operating  expenses per BOE
associated with the South Horseshoe Bayou production added in 1997.

     Depreciation,   Depletion,   Amortization  and  Impairment.   Depreciation,
depletion and amortization  ("DD&A") increased 23% to $4.0 million for the third
quarter 1997 compared with $3.3 million in 1996 because of increased  production
from reserve acquisitions and new wells drilled. DD&A per BOE decreased slightly
to $3.17 in the third  quarter  1997  compared to $3.22 in 1996.  Impairment  of
producing oil and gas  properties was $288,000 for the third quarter of 1997 due
to one high-cost marginal well and lower product prices. There was no impairment
of proved properties for the third quarter of 1996.

     DD&A increased 32% to $12.1 million for the nine months ended September 30,
1997  compared  with $9.1 million in 1996 because of increased  production  from
reserve  acquisitions and new wells drilled.  DD&A per BOE decreased to $3.28 in
the nine months ended  September 30, 1997 compared to $3.34 in 1996.  Impairment
of  producing  oil and gas  properties  was  $804,000  for the nine months ended
September  30,  1997 due to  several  high-cost  marginal  wells.  There  was no
impairment of proved properties for the nine months ended September 30, 1996.

     Abandonment and impairment expenses for unproved  properties  increased 97%
to $1.4 million in the third  quarter 1997 compared with $691,000 in 1996 due to
expense associated with expiring leases,  primarily in Oklahoma,  and due to the
impairment  of acreage  associated  with a  marginal  well  drilled in  Wyoming.
Abandonment and impairment expenses for unproved properties was $1.8 million for
the nine months ended  September  30, 1997  compared  with $1.2 million in 1996.
This 48% increase is due to the same causes noted for the third quarter.

                                      -13-


     Exploration.  Exploration  expense  decreased  $371,000  to $988,000 in the
third  quarter  1997  compared  to $1.4  million  in 1996.  Exploration  expense
decreased  $1.7 million to $4.0 million for the nine months ended  September 30,
1997  compared  to $5.7  million in 1996  because  several  larger  3-D  seismic
programs  were  completed  in 1996  combined  with better  exploratory  drilling
results in the nine months ended September 30, 1997 compared with 1996.

     General and Administrative.  General and administrative  expenses increased
7% to $1.5 million in the third  quarter 1997  compared to $1.4 million in 1996.
General and  administrative  expenses  increased $983,000 or 19% to $6.0 million
for the nine months ended  September  30, 1997  compared to $5.1 million in 1996
primarily  because  of  increased   compensation  expense  associated  with  the
Company's incentive plans and charitable contributions.

     Other.  Other consists of legal and settlement  expenses in connection with
disputes in the normal course of business.  This expense increased to $69,000 in
the third quarter 1997 compared to $18,000 in 1996.

     Non-Operating Income and Expense. Net interest income increased $742,000 to
$235,000 in the third quarter 1997 compared to $507,000 of net interest  expense
in 1996 as a result of the  repayment  of debt with the  proceeds of the sale of
common stock in the first quarter of 1997.

     Net interest expense  decreased $1.2 million to $23,000 for the nine months
ended  September  30, 1997  compared to $1.2 million of net interest  expense in
1996 as a result  of the  repayment  of debt  with the  proceeds  of the sale of
common stock in the first quarter of 1997.

     Income  Taxes.  The  effective  income tax rate for the third  quarter 1997
increased to 35.4%  compared to 33.6% in 1996.  The  effective  tax rate for the
nine months ended September 30, 1997 increased to 35.5% compared to 32.5% in the
1996  period  because of the  decreased  impact of Section  29 tax  credits  and
percentage  depletion,  and because of higher state income taxes which  resulted
from the $24.4  million  increase in income from  continuing  operations  before
income taxes compared to the 1996 period.

     Net Income.  Net income for the third  quarter 1997  increased  $985,000 to
$4.1  million  compared to $3.1 million in 1996.  This  increase  resulted  from
higher  operating  income  resulting  from  significantly  increased  production
partially offset by increased operating expenses.

     Net income for the nine months ended  September  30, 1997  increased  $15.6
million  to $21.5  million  compared  to $5.9  million  in 1996.  This  increase
resulted from higher  operating income  resulting from  significantly  increased
production  partially offset by increased  operating  expenses and from 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 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,  during the first quarter 1997, the
issuance of common  stock.  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  and  stockholder  dividends.  The  Company
generally  finances its  exploration  and  development  programs from internally
generated  cash flow,  bank debt,  and cash and cash  equivalents  on hand,  and
continually reviews its capital expenditure budget based on changes in cash flow
and other factors.

     Cash Flow.  Net cash  provided  by  operating  activities  increased  $17.2
million to $34.2  million for the nine months ended  September 30, 1997 compared
to $17.1 million for 1996  primarily  due to increased  revenue from oil and gas
sales.

                                      -14-


     Net cash used in investing  activities  increased  10% to $33.1 million for
the nine months ended September 30, 1997 compared with $30.1 million in 1996 due
primairly  to  increased  capital  expenditures  partially  offset by  decreased
property  acquisitions  and  increased  property  dispositions.   Total  capital
expenditures  for the nine  months  ended  September  30, 1997  increased  $18.4
million to $38.4  million  compared  to $20.0  million in 1996 due to  increased
drilling activity.

     Net cash  provided by financing  activities  was $14.3 million for the nine
months ended  September  30, 1997 compared to $15.7 million in 1996. In February
1997, the Company closed the sale of 2,000,000  shares of common stock at $25.00
per share.  In March 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 cash  proceeds of $51.2  million.
During the nine months ended  September 30, 1997,  the Company's net  borrowings
decreased  $35.8  million,  compared to a net  increase in  borrowings  of $16.7
million for the nine months ended September 30, 1996.

     The  Company  had $18.8  million in cash and cash  equivalents  and working
capital of $15.6  million as of September  30, 1997  compared to $3.3 million of
cash and cash  equivalents  and working capital of $13.9 million at December 31,
1996. This increase resulted  primarily from the proceeds of the equity offering
and from the sale of the Company's  Russian  joint venture  interest in February
1997,  offset by an increase in capital  expenditures and trade accounts payable
due to increased drilling activity.

     Credit  Facility.  In April 1996, the Company  extended its credit facility
with two banks to provide a $60 million secured three-year  revolving loan which
thereafter converts at the Company's option to a five-year  amortizing loan. The
amount  which may be borrowed  from time to time  depends  upon the value of the
Company's oil and gas properties and other assets. The Company's  borrowing base
is currently $60 million and is redetermined annually. In early 1997 the Company
voluntarily  reduced the commitment under the credit facility to $10 million and
in November  1997  increased  the  commitment  to $20  million.  The Company may
increase the  commitment up to the amount of the borrowing  base before the next
redetermination, subject to approval by the bank. During the first quarter 1997,
the Company repaid the outstanding  debt under this facility of $33.9 million at
December 31, 1996. When the debt to  capitalization  ratio is less than 30%, the
outstanding  balances  accrue  interest  at the  Company's  option of either the
banks' prime rate or LIBOR plus 1/2% and 3/4% for the  revolving and term loans,
respectively.   The  interest   rate   increases  as  the   Company's   debt  to
capitalization   ratio  increases.   The  loan  under  the  credit  facility  is
collateralized  by  substantially  all of the  Company's  producing  oil and gas
properties.  The credit  facility  provides for,  among other things,  covenants
including maintenance of stockholders' equity at a specified level,  limitations
on additional  indebtedness  and payment of dividends.  The credit  facility was
partially  utilized in November 1997 in  conjunction  with the  acquisition of a
group of producing properties in Oklahoma.

     Panterra,  in which the Company has a 74% ownership,  has a separate credit
facility with a $26 million  borrowing base and $10.5 million  outstanding as of
September 30, 1997. The partnership  intends to use the available credit to fund
a portion of its planned 1997 capital expenditures.

     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 1997.

     For 1997, the Company  anticipates  spending  approximately $85 million for
capital and  exploration  expenditures  with $28 million  allocated for domestic
acquisitions,  $46 million for low to moderate  risk  domestic  exploration  and
development and $11 million for large target,  higher risk domestic  exploration
and development.

     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 exploratory  activity which could
lead to funding requirements for further development.

                                      -15-


     On February 12, 1997,  the Company sold its Russian  joint venture to KMOC.
The Company received cash  consideration of approximately  $5.6 million,  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.  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.

     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 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, $3.2 million in cash
and a commitment  for $45.0 million of senior debt financing in return for a 45%
interest in the new company.  The  agreement  is subject to certain  conditions,
including final resolution of regulatory approvals and project financing.  Summo
is currently  conducting  tests of the ground water quality to address  concerns
raised on appeal during the permitting  process.  These tests are anticipated to
be completed by year-end. The Company has agreed to provide interim financing of
up to $2.2  million  for the  Project in the form of a loan to Summo due in June
1999. As of September 30, 1997,  $1.3 million was  outstanding  under this loan.
Additional amounts totaling $537,000 have been advanced to Summo under this loan
since  September 30, 1997. Any principal and interest  amounts  outstanding  are
convertible into shares of Summo common stock anytime after December 31, 1997 at
the  option  of  the  Company.  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.

     In November  1997,  the Company  completed  the  acquisition  of  producing
properties  in the SW  Mayfield  Field of  Beckham  County,  Oklahoma  for $20.3
million.  The acquisition  complements the Company's existing  operations in the
Anadarko Basin,  adds 5,600 MCFE per day of current net production from 40 wells
effective  November  1, 1997,  and  offers  significant  additional  development
opportunities  in several  formations.  The  acquisition was funded with cash on
hand and borrowings under the Company's credit facility.

Effects of Inflation and Changing Prices

     The Company's  results of operations and cash flow are affected by changing
oil  and  gas  prices.  If  oil  and  gas  prices  increase,  there  could  be a
corresponding  increase  in the cost to the  Company  for  drilling  and related
services as well as an  increase in  revenues.  The Company has  experienced  an
increase in the cost of drilling and related  services due to higher  demand for
these services services and limited capacity. Notwithstanding,  inflation within
the United States has had a minimal effect on the Company. The Company's foreign
interests may be adversely  affected by inflation in Russia and other countries.
The Company cannot predict the extent of any such effect.
