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 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.

The  Company  accounts  for  its  37%  ownership   interest  in  Summo  Minerals
Corporation  ("Summo")  under the  equity  method of  accounting.  For the three
months  ended  March 31,  1998,  the  Company  recorded a loss of $61,000 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


                                       -7-


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 has  completed  tests of the ground water  quality to
address concerns raised on appeal during the permitting process.  The results of
these tests support the original  conclusions  and  recommendations  made by the
Bureau of Land  Management when the Project was initially  approved.  A decision
from the Interior Board of Land Appeals is expected in mid 1998. The Company has
agreed to provide  interim  financing of up to $2,725,000 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 March 31,  1998,  $2,316,000  was
outstanding  under this loan.  Additional  amounts  totaling  $209,000 have been
advanced to Summo under this loan since March 31, 1998. At the Company's option,
any principal and interest  amounts  outstanding are convertible  into shares of
Summo common stock anytime  after June 30, 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 June 30, 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.  Management  believes  the  long-term  outlook  for  copper  prices is
favorable and plans to continue  providing  interim  financing during 1998 until
Summo  receives  regulatory  approval and copper  prices  recover  adequately to
justify construction using permanent  financing.  There can be no assurance that
the Company will realize a return on its investment in Summo or the Project.

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.

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.

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.  The  outstanding  dilutive
securities  for the  three-month  periods  ended  March  31,  1998 and 1997 were
138,563 and 103,633, respectively. 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 three months ended March 31, 1997.  Restated  basic net income per share for
the three months  ended March 31, 1997 was $1.21  compared to primary net income
per share of $1.20 as reported.

Note 6 - Income Taxes

Federal  income tax expense for 1998 and 1997 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 Section 29 credits and percentage depletion
in 1998 and the effect of state income taxes partially  offset by Section 29 tax
credits and percentage depletion in 1997.

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.

     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.

     St. Mary has two principal equity investments,  Summo Minerals  Corporation
("Summo"),  a North American  copper mining  company,  and until early 1997, the
Company's  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.  Effective  February  12, 1997,  the Company sold its Russian  joint
venture.

     The Company  receives  significant  royalty income from its south Louisiana
fee lands.  Management  expects the Company's royalty income to increase in 1998
with the  completion  of the St.  Mary  Land &  Exploration  No. 3 well at South
Horseshoe  Bayou in January 1998 which  followed the completion of the discovery
well in the prospect in February 1997 and its subsequent  recompletion  in April
1998.  The Company  owns a 25% working  interest and royalty  interests  between
approximately  19% and 22% in this field for combined  net revenue  interests of
between  approximately  37% and 40%,  depending on the depth of production.  The
Company and the lessees have identified several geologic  objectives for testing
in future years.

     The results of operations  include several  significant  acquisitions  made
during  recent years and the  subsequent  development  of those  properties.  In
December  1995, the Company  acquired two different  interests in the Box Church
Field in its ArkLaTex region for $2.2 million and several  additional  interests
in 1996 for  $580,000.  Development  of the field has occurred with the drilling
and  completion  of three  wells in 1996 and eleven  wells in 1997.  In 1998 the
Company  anticipates  the completion of three wells in progress at year-end 1997
and the drilling of four  additional  wells to complete the  development  of the
field. The Company purchased a 90% interest in the producing properties of Siete
Oil & Gas  Corporation  for $10.0 million in June 1996 and completed a series of
follow-on  acquisitions of smaller  interests in these properties  totaling $5.7
million during 1996,  1997 and the first quarter of 1998.  These  properties are
located in the Permian Basin of New Mexico and west Texas. Management expects to
acquire  additional  interests in the Siete properties as they become available.
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 $20.3 million.  Management  anticipates  drilling  several wells in
1998 to test the geologic  ideas  identified at the time of  acquisition of this
field.  Several smaller  acquisitions  were also completed  during 1997 and 1996
totaling $560,000 and $2.8 million, respectively.



                                      -10-


     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.

     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 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  5.2
million MMBtu of its remaining  1998 gas production at an average fixed price of
$2.21 per MMBtu and  approximately  30,000  barrels  of its  remaining  1998 oil
production  at an  average  fixed  price of  $17.95  per Bbl.  The  Company  has
purchased  options  resulting in price collars and price floors on approximately
22,200  barrels  of the  Company's  remaining  1998 oil  production  with  price
ceilings of $24.00 per Bbl and price  floors of $20.00 per Bbl.  The Company has
also  purchased  options  resulting  in price  collars  and price  floors on 1.5
million MMBtu of the Company's remaining 1998 gas production with price ceilings
between  $2.67 and $3.00 per MMBtu and price floors  between $1.95 and $2.00 per
MMBtu.

     Oil and Gas Production Revenues.  Oil and gas production revenues decreased
$2.0 million,  or 10% to  $19.0 million  for the first  quarter 1998 compared to
$21.0 million  for the first quarter 1997. Oil production  volumes  increased 8%
and gas production  volumes increased 16% for the first quarter 1998 compared to
1997.  Average net daily production  reached  15.3 MBOE in 1998 compared to 13.4
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 Siete  properties.  Successful  drilling


                                      -12-


results in the Box Church Field in Texas and the South  Horseshoe Bayou in south
Louisiana also  contributed to the first quarter 1998 production  increase.  The
average  realized oil price for the first  quarter 1998  decreased 27% to $14.90
per Bbl,  while  realized gas prices  decreased 18% to $2.24 per Mcf, from their
respective  1997 levels.  The Company  hedged 33,600 Bbls of its oil  production
during the first  quarter 1998 at an average  NYMEX price of $18.29 per Bbl. The
Company  purchased options resulting in price collars and price floors on 55,500
Bbls of its first quarter 1998 oil production with price ceilings between $23.00
and  $24.00 per Bbl and price  floors  between  $19.00  and $20.00 per Bbl.  The
Company  realized a  $200,000  increase  in oil  revenue or $.62 per Bbl for the
first quarter 1998 on these  contracts  compared to a $211,000  decrease or $.71
per Bbl in 1997.  The Company also hedged 1.0 million MMBtu of its first quarter
1998 gas production at an average indexed price of $2.15 per MMBtu and purchased
options  resulting  in price  collars and price  floors on 900,000  MMBtu of its
first quarter 1998 gas production  with price  ceilings  between $2.67 and $3.00
per MMBtu and price  floors of $2.00 per MMBtu.  The Company  realized a $78,000
increase in gas  revenues  or $.01 per Mcf for 1998 from these  hedge  contracts
compared to an $895,000 decrease or $.16 per Mcf in the first quarter 1997.

     Oil and Gas Production Costs. Oil and gas production costs consist of lease
operating expense and production taxes. Total production costs decreased $35,000
or 1% for the first quarter 1998 from comparable 1997 levels.  Total oil and gas
production costs per BOE declined 13% to $2.86 in 1998 compared to $3.29 per BOE
in 1997.

     Depreciation,   Depletion,   Amortization  and  Impairment.   Depreciation,
depletion and amortization  expense ("DD&A")  increased $1.4 million,  or 35% to
$5.4 million  in the first quarter 1998 compared with $4.0 million in 1997. DD&A
per BOE increased 18% to $3.89 in the first quarter 1998 as compared to $3.31 in
1997.  This increase  resulted from new properties  acquired and drilled in 1997
and the first quarter of 1998.  The Company  recorded  impairments of proved oil
and gas  properties  of  $368,000 in the first  quarter  1998  compared  with no
impairments  in  the  comparable  1997  period.   These  charges  resulted  from
unsuccessful  development  drilling  results  in two  fields  in  the  Company's
Mid-Continent  region  and an  unsuccessful  recompletion  attempt in a field in
Mississippi.

     Abandonment  and impairment of unproved  properties  increased  $153,000 to
$303,000 in 1998 compared to $150,000 in 1997 due to additional  abandonments of
expired leases during the first quarter 1998.

     Exploration.   Exploration  expense  increased  $2.0  million  or  146%  to
$3.4 million for first quarter 1998 compared with $1.4 million in 1997 primarily
as a result of unsuccessful  exploratory drilling results in south Louisiana and
Oklahoma  and the  payment  of  $795,000  for  delay  rentals  in the  Company's
Atchafalaya Bay prospect area.

     General and Administrative. General and administrative expenses declined 2%
to  $2.9 million  for the first  quarter  1998 as  compared  to 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  increased $70,000 in the first quarter 1998 compared
with the first quarter 1997,  primarily due to legal expenses in 1998 associated
with the pending  litigation  that seeks to recover  damages  from the  drilling
contractor for the St. Mary Land & Exploration #1 well at South  Horseshoe Bayou
and the benefit of a non-recurring insurance recovery of $68,000 in 1997.



                                      -13-


     Equity in Income and Loss 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  or loss  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 $61,000 in the first quarter 1998 and $116,000 in 1997.

     Non-Operating  Income and Expense.  Net interest expense decreased $165,000
to $239,000 in the first quarter 1998 due to the reduction of the Company's debt
with the proceeds of the sale of common stock in the first quarter of 1997.
 
     Income Taxes. Income tax expense was $775,000 in the first quarter 1998 and
$6.4  million  in  1997,  resulting  in  effective  tax  rates  of 32% and  36%,
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  and a $9.7  million  gain  on the  sale of the
Company's Russian joint venture in the first quarter 1997.

     Net Income. Net income for the first quarter 1998 decreased $9.9 million or
86% to $1.7 million  compared to $11.6 million in 1997. A 16% and 8% increase in
gas and oil volumes,  respectively,  offset by 18% and 27%  decreases in gas and
oil prices,  respectively,  resulted in a $2.0  million  decrease in oil and gas
production  revenues for the first quarter 1998. A $9.7 million gain on the sale
of the  Company's  Russian joint venture in the first quarter 1997 and increases
in exploration expenses and DD&A associated with increased production volumes in
the first quarter 1998  contributed  to a $15.8 million  decrease in income from
operations. 

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 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.  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  $2.6  million  or 18% to $17.3  million  in the  first  quarter  1998
compared  to $14.6  million in 1997.  Higher  exploration  expenses  and reduced
receipts  for oil and gas  revenues  were  offset  by  lower  production  taxes,
increased  accounts payable  resulting from increased  operating  activity,  and
decreased  accounts  receivable  primarily due to reduced prices for oil and gas
sales.  Also,  in the first  quarter of 1997 the Company  made a cash payment of
approximately $1.6 million in satisfaction of liabilities  previously accrued by
the Company under its SAR plan compared to a  corresponding  payment of $351,000
in the first quarter 1998.

     Net cash used in investing  activities in the first quarter 1998  increased
$12.8  million or 209% to $18.9 million  compared to $6.1 million in 1997.  This
increase was  primarily due to a $5.9 million  increase in capital  expenditures
for the Company's  drilling  programs in 1998 and $ 5.6 million in cash received
from the sale of the Company's  Russian joint venture in the first quarter 1997.
Total first quarter 1998 capital expenditures, including acquisitions of oil and
gas properties, were $19.3 million compared to $13.7 million in 1997.



                                      -14-


     The Company was able to apply the majority of the  proceeds  from the sales
of oil and  gas  properties  in 1997  and  1996 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 used by financing activities was $1.8 million in the first quarter
1998  resulting  from net repayments of long-term debt and payments of dividends
to shareholders  compared to net cash provided by financing  activities of $15.3
million in the first quarter 1997.  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.

     The  Company  had $3.8  million in cash and cash  equivalents  and  working
capital of $1.0  million as of March 31, 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 decreased
cash receipts for oil and gas sales due to price declines,  payments for capital
expenditures,  property  acquisitions and exploration  expenses and reduction of
long-term debt.  Working capital decreased due to the reduction in cash and cash
equivalents,  decreased accounts receivable, primarily for oil and gas sales due
to price declines, and increased accounts payable and accrued expenses resulting
from increased drilling activity.

     Credit  Facility.  On April 1, 1996,  the Company  amended and restated its
credit facility with two banks to provide a collateralized  three-year revolving
loan facility which  thereafter  converts at the Company's option to a five-year
term loan.  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
million to $60 million in February  1997 and  further  increased  in May 1998 to
$115 million based on increases in the Company's  estimated net proved  reserves
in 1996 and 1997. Outstanding revolving loan balances under the Company's credit
facility,  which  were $14.0  million  and $14.5  million at March 31,  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 the banks'
prime rate or LIBOR plus 1/2% when the Company's debt to total capitalization is
less than 30%,  up to a maximum  of either  the  banks'  prime rate plus 1/8% or
LIBOR plus 1-1/4% when the Company's debt to total  capitalization ratio exceeds
50%. The credit facility is collateralized by a mortgage of substantially all of
the Company's domestic oil and gas properties. The credit facility provides for,
among other things,  covenants limiting additional recourse  indebtedness of the
Company,  investments  or  disposition  of assets  by the  Company  and  certain
restrictions on the payment of cash dividends to shareholders.

     Panterra,  in which the  Company has a 74%  general  partnership  ownership
interest,  has a separate credit facility with a $27.0 million borrowing base as
of January 1, 1998, and $10.0 million and $11.0 million  outstanding as of March
31, 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%.  The Company  intends to use the  available  credit under the
Panterra credit  facility to fund a portion of its 1998 capital  expenditures in
the Williston Basin.



                                      -15-


     Sale of 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.

     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.

     In 1998, the Company has budgeted  approximately  $94.0 million for capital
and  exploration   expenditures   with  $56.0  allocated  for  ongoing  domestic
exploration and development in its core operating areas, $20.0 million for niche
acquisitions  of  producing  properties  and  $18.0  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  development  and  exploratory
activity which could lead to funding requirements for further development.

     The Company, through a subsidiary,  owns 9.9 million shares or 37% of Summo
Minerals Corporation, a North American copper mining company focusing on finding
late exploration stage, low to medium sized copper deposits in the United States
amenable to the SX-EW extraction  process. 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 has completed tests of the ground water
quality to address concerns raised on appeal during the permitting process.  The
results of these tests support the original conclusions and recommendations made
by the Bureau of Land  Management  when the Project was  initially  approved.  A
decision  from the Interior  Board of Land Appeals is expected in mid 1998.  The
Company has agreed to provide  interim  financing  of up to $2.7 million for the
Project in the form of a loan to Summo due in June 1999.  As of March 31,  1998,
$2.3  million  was  outstanding  under this loan.  Additional  amounts  totaling
$209,000 have been  advanced to Summo under this loan since March 31, 1998.  Any
principal and interest amounts  outstanding are convertible into shares of Summo
common  stock  anytime  after June 30, 1998 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.  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.  Management  believes the  long-term  outlook for copper prices is
favorable and plans to continue  providing  interim  financing during 1998 until
Summo receives final regulatory approval and copper prices recover adequately to
justify construction using permanent  financing.  There can be no assurance that
the Company will realize a return on its investment in Summo or the Project.




                                      -16-


     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.

     Impact  of the Year  2000  Issue.  The Year  2000  Issue is the  result  of
computer  programs  being  written  using two digits  rather than four, or other
methods,   to  define  the  applicable   year.   Computer   programs  that  have
date-sensitive  software 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,  send  invoices or engage in similar  normal
business activities.

     The  Company  has  conducted  a  review  of its  computer  systems  and has
determined that the computer system used by Panterra will need to be replaced in
order to properly utilize dates beyond December 31, 1999. Panterra has initiated
a review of available replacement systems and believes conversion to a suitable,
Year 2000  compliant  system can be  completed,  tested and  operational  before
December  31, 1999 at a cost that is not  expected to have a material  effect on
the Company's  results of operations.  If replacement of the Panterra  system is
not completed timely, the Year 2000 Issue could have a significant impact on the
operations  of  Panterra.   The  Company  presently  believes  that  other  less
significant  systems  can be  upgraded  to  mitigate  the Year 2000  Issue  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  Company  has  initiated  formal  communications  with its  significant
suppliers and  purchasers and  transporters  of oil and natural gas to determine
the extent to which the Company is vulnerable to those third parties' failure to
remediate their own Year 2000 Issues. There can be no guarantee that the systems
of these third parties will be converted timely, or that a failure to convert by
another company would not have a material adverse effect 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 June  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.



                                      -17-


     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.

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. As oil and gas prices increase,  the cost of acquisitions of producing
properties increases,  which could limit the number and accessibility of quality
properties on the market.

     The  Company  has  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.  If  these
shortages persist, there could be continued increases in the cost to the Company
of exploration, drilling and production of oil and gas.
