ITEM 1.  BUSINESS

Background

         St. Mary Land & Exploration Company ("St. Mary" or the "Company") is an
independent energy company engaged in the exploration,  development, acquisition
and  production of natural gas and crude oil. St. Mary's  operations are 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. As
of  December  31,  1997,  the  Company  had  estimated  net proved  reserves  of
approximately  11.5 MMBbls of oil and 196.2 Bcf of natural  gas, or an aggregate
of 265.2 BCFE (87% proved  developed,  74% gas) with a PV-10 Value before tax of
$262.0 million.

         From January 1, 1995  through  December  31,  1997,  the Company  added
estimated net proved  reserves of 241.1 BCFE at an average Finding Cost of $4.33
per BOE. In 1997 the Company  replaced 358% of production at an average  Finding
Cost of $4.99  per BOE and  increased  estimated  net  proved  reserves  by 39%.
Production  increased  32% in 1997 to a total of 30.0  BCFE,  or  average  daily
production  of  82.3  MMcf  per  day.  The  Company's  1998  capital  budget  of
approximately  $94.0 million includes (i) $56.0 million for ongoing  development
and  exploration  programs in the core operating  areas,  (ii) $20.0 million for
niche  acquisitions  of oil and gas  properties  and  (iii)  $18.0  million  for
high-risk, large-target exploration prospects.

         The  principal  offices of the  Company  are  located  at 1776  Lincoln
Street,  Suite 1100,  Denver,  Colorado 80203, and its telephone number is (303)
861-8140.

Business Strategy

         St. Mary's objective is to build shareholder  value through  consistent
economic  growth in reserves and  production  and the resulting  increase in net
asset value per share, and cash flow per share and earnings per share. A focused
and balanced  program of low to medium-risk  exploration,  development and niche
acquisitions  in each of its core  operating  areas is  designed  to provide the
foundation  for  steady  growth  while the  Company's  portfolio  of  high-risk,
large-target  exploration prospects have the potential to significantly increase
the Company's reserves and production. All investment decisions are measured and
ranked by their  risk-adjusted  impact on per share value.  The Company does not
pursue  growth  for the sake of  growth.  Principal  elements  of the  Company's
strategy are as follows.

         Focused  Geographic  Operations.  The Company focuses its  exploration,
development and acquisition activities in five core operating areas where it has
built  a  balanced   portfolio   of  proved   reserves,   development   drilling
opportunities  and high-risk  large-target  exploration  prospects.  The Company
believes that its extensive  leasehold position is a strategic asset. Since 1992
St. Mary has  expanded its  technical  and  operating  staff and  increased  its
drilling, production and operating capabilities. Senior technical managers, each
with over 25 years of experience head up regional technical offices located near
core properties and are supported by centralized administration in the Company's
Denver office. St. Mary has knowledgeable and experienced professionals at every
level of the  organization  and has been able to  recruit  and  retain a team of
employees that average  almost seven years of tenure with the Company.  St. Mary
believes that its  long-standing  presence,  its  established  networks of local
industry  relationships and its extensive acreage holdings in its core operating
areas  provide a significant  competitive  advantage.  In addition,  the Company
believes  that it can  continue  to expand its  operations  without  the need to
proportionately increase the number of employees.

                                      -4-

         Exploitation and Development of Existing  Properties.  The Company uses
its comprehensive  base of geological,  geophysical,  engineering and production
experience  in each of its core  operating  areas to  source  prospects  for its
ongoing,  low to medium-risk  development  and  exploration  programs.  St. Mary
conducts  detailed  geologic studies and uses an array of technologies and tools
including 3-D seismic  imaging,  hydraulic  fracture and  reservoir  stimulation
techniques,  and  specialized  logging  tools to maximize  the  potential of its
existing  properties.  During 1997, the Company  participated in 133 gross wells
with an 85% success rate and 30 recompletions with an 87% success rate.

         Large-Target  Prospects.  The Company  invests 15% to 20% of its annual
capital budget in higher-risk,  large-target  exploration projects and currently
has an  inventory  of eight  active  projects in its core areas.  The  Company's
strategy is to test four or more of these large exploration  prospects each year
which in total have the potential, if successful,  to increase the Company's net
reserves  by 25% or more.  St.  Mary  seeks to  invest in a  diversified  mix of
large-target  exploration  projects and generally limits its capital exposure by
participating with other experienced  industry partners.  St. Mary plans to test
several  large-target  prospects in south Louisiana  during 1998,  including its
Atchafalaya Bay, Belle Bayou and Patterson prospects.

         Selective  Acquisitions.  The  Company  seeks to make  selective  niche
acquisitions of oil and gas properties that complement its existing  operations,
offer  economies  of scale  and  provide  further  development  and  exploration
opportunities based on proprietary  geologic concepts.  Management believes that
the Company's focus on smaller,  negotiated  transactions  where the Company has
specialized geologic knowledge or operating experience has enabled it to acquire
attractively priced and under-exploited properties. During the last three years,
the  Company  completed  acquisitions  totaling  $56.4  million  at  an  average
acquisition cost of $4.17 per BOE.

         Strategic Relationships.  The Company cultivates strategic partnerships
with independent oil and gas operators  having focused  regional  experience and
specialized technical skills. The Company's strategy is to serve as operator or,
alternatively,  to maintain a majority  interest in such ventures to ensure that
it  can  exercise   significant   influence  over  development  and  exploration
activities.  In addition the Company seeks industry  partners who are willing to
co-invest  on  substantially  the same basis as the Company.  For  example,  the
Company's  operations in the  Williston  Basin are  conducted  through  Panterra
Petroleum  ("Panterra")  in  which  St.  Mary  holds a 74%  general  partnership
interest. The managing partner of Panterra is Nance Petroleum  Corporation,  the
principal of which has over 25 years of experience in the Williston Basin.

         Financial  Flexibility.  A conservative use of financial  leverage  has
long been a cornerstone of St. Mary's  strategy.  St.  Mary  believes  that  the
preservation  of a strong  balance sheet is a competitive  advantage  because it
enables the Company to act quickly and decisively to capture  opportunities  and
provides the financial resources to weather periods of volatile commodity prices
or escalating costs. St. Mary has been profitable for eleven consecutive years.

Significant Developments Since December 31, 1996

         Deep Gas Exploration Success.  In February 1997 St. Mary  announced  an
important deep gas discovery on its fee lands in south Louisiana at the St. Mary
Land &  Exploration  No.  2 well  at  South  Horseshoe  Bayou  in a pay  zone at
approximately  17,300 feet. The well was completed at an initial rate of 20 MMcf
of gas per day.  In January  1998,  the St.  Mary Land &  Exploration  No. 3 was
completed  as a successful  confirmation  well at over 35 MMcf of gas per day in
the upper pay zone. The Company  expects to recomplete the No. 2 well in a lower
pay zone at approximately 17,900 feet in Apirl 1998.

         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.

         Russian Joint Venture. In February 1997, the Company sold its interests
in its  Russian  joint  venture to Khanty  Mansiysk  Oil  Corporation  ("KMOC"),
formerly known as Ural Petroleum  Corporation,  for consideration totaling $17.6
million.

         Box Church Development.  Following the significant discovery in the Box
Church Field in 1996, which added 26.4 Bcf of estimated net proved reserves, the
Company has  drilled and  completed  eleven  development  wells in 1997 and have
three wells  awaiting  completion  in 1998.  The Company's  development  program
increased  gross  production  at the Box Church Field to over 22 MMcf per day in
December  1997  compared  to 2.5 MMcf when the field was  acquired.  The Company
plans to drill four additional wells at Box Church in 1998.

         Acquisitions of Oil and Gas Properties.  In 1997 the Company  completed
five  acquisitions  of oil and gas properties  for $27.3  million,  including an
expansion of the Company's  interests in the Anadarko Basin for $20.3 million, a
$3.8 million acquisition of operated  properties in Louisiana,  and supplemental
acquisitions of $3.2 million in the Permian and Williston Basins.

         Oil and  Gas  Property  Sales.  In  order  to  continue  to  focus  and
rationalize its operations,  the Company sold certain non-operated  interests in
south Texas in May 1997 and realized a net gain of approximately $4.2 million.

         Lafayette Exploration Office. In  1997 St. Mary  opened an  exploration
office in  Lafayette,  Louisiana  as part of  its strategy to expand  activities
in the transition zone of the Gulf Coast.

     (1)  Includes  reserves  associated with  properties in Alabama,  Colorado,
          Kansas, Mississippi, Utah, Wyoming and Canada.

         Mid-Continent  Region. The Company has been active in the Mid-Continent
region since 1973 where the Company's  operations  are managed by its 25-person,
Tulsa,  Oklahoma  office.  The Company has ongoing  exploration  and development
programs in the  Anadarko  Basin of Oklahoma and the  Sherman-Marietta  Basin of
southern  Oklahoma and northern Texas.  The  Mid-Continent  region accounted for
33.5% of the Company's  estimated net proved reserves as of December 31, 1997 or
88.8 BCFE (79% proved  developed and 94% gas).  The Company  participated  in 73
gross  wells  and   recompletions   in  this  region  in  1997,   including   18
Company-operated wells.

         The  Company's  development   and  exploration   budget  in  the   Mid-
Continent  region for 1998 totals $32 million.  The Company  plans to operate 22
wells (62% of the Mid-Continent  budget) in the Mid-Continent region during 1998
and to utilize four to five drilling  rigs  throughout  the year.  St. Mary also
expects to  participate  in an additional 30 to 40 wells to be operated by other
entities.

         Anadarko Basin. The Company's 1998 Mid-Continent  capital budget of $32
million  will focus on higher  potential  prospects  in the  Morrow,  Hunton and
Springer formations  targeting per well reserves of 5 to 30 Bcf of gas. The 1998
Mid-Continent  program is  balanced  by  additional  lower-risk  drilling in the
Granite  Wash play.  In recent  years the Company  has  achieved  success  rates
exceeding 90 percent in the Granite Wash based on an extensive geologic study of
the  formation  in Washita and Beckham  Counties,  Oklahoma,  undertaken  by the
Company during 1993 and 1994.

         Sherman-Marietta  Basin.  In the  Sherman-Marietta  Basin of  northeast
Texas,  St. Mary has  identified a series of prospect  areas to the south of the
Red River in Cooke and  Grayson  Counties.  Geologic  studies  of the  complexly
faulted edge of this basin have yielded  prospects  in both the  shallower  Penn
sands as well as the deeper Oil Creek and Arbuckle  formations.  A twelve square
mile 3-D seismic survey at the Company's  South Dexter prospect area in 1994 led
to a discovery in the  Ordovician Oil Creek sands during 1996. St. Mary plans to
drill several tests in its South Dexter prospect area in 1998.

                                      -7-
<PAGE>

         In addition, the Company has a 41% working interest in its large-target
Red Branch  prospect that is located in Cooke County,  Texas.  This Arbuckle and
Oil  Creek prospect is scheduled  for late  1998 and  St. Mary will  operate the

         Carrier Prospect.  Within its inventory of large-target prospects,  the
Company  holds an  aggregate  11.2%  working  interest  in 25,800  acres in Leon
County,  Texas in the Cotton Valley reef play.  The Company's  Carrier  Prospect
acreage is located  approximately nine miles east of the trend of the industry's
initial prolific reef discoveries and targets  potentially larger reefs that are
postulated  to have  developed  in the  deeper  waters of the basin  during  the
Jurassic  period.  The Company and its  partners  completed a 52 square mile 3-D
seismic survey in 1997 and expect to complete  processing and  interpretation of
the seismic data and final  evaluation of the  prospective  acreage by mid 1998.

         South  Louisiana  Region.  The Company's  operations in south Louisiana
include  its  royalty  interests  in  St.  Mary  Parish,  working  interests  in
properties acquired in 1997 and a number of large-target  prospects located both
on its fee lands and in separate  prospect areas in south  Louisiana.  The south
Louisiana  region  accounted  for 21.2% of the  Company's  estimated  net proved
reserves as of December 31, 1997 or 56.4 BCFE (97% proved developed, 88% gas).

         Fee Lands.  The Company owns 24,914  acres of fee lands and  associated
mineral rights in St. Mary Parish,  located  approximately 85 miles southwest of
New  Orleans.  St. Mary also owns a 25% working  interest in  approximately  300
acres located offshore and immediately  south of the Company's fee lands.  Since
the initial discovery on the Company's fee lands in 1938, cumulative oil and gas
revenues,  primarily landowner's royalties,  to the Company from the Bayou Sale,
Horseshoe Bayou and Belle Isle Fields on its fee have exceeded $215 million. St.
Mary currently  leases 17,556 acres of its fee lands and has an additional 7,358
acres that are presently  unleased.  The Company's principal lessees are Texaco,
Vastar,  Oryx,  Mobil and Sam Gary Jr.  and  Associates,  a private  exploration
company headquartered in Denver.

         St.  Mary  has   encouraged   development   drilling  by  its  lessees,
facilitated  the  origination of new prospects on acreage not held by production
and stimulated exploration interest in deeper,  untested horizons. The Company's
major  discovery on its fee lands at South  Horseshoe  Bayou in early 1997 and a
subsequent  successful  confirmation  well in early 1998 proved that significant
accumulations  of gas could be sourced and trapped at depths  below 16,000 feet.
Net production  from the Company's fee lands increased by 13% in 1997 and 16% in
1996 as a result of the continuing  development  of the shallower  formations on
the  property and  production  from the deep gas  discovery  at South  Horseshoe
Bayou. The Company's fee properties  contributed  approximately $8.8 million, or
11.6%, of St. Mary's gross oil and gas production revenues in 1997 and currently
have gross production of over 60 MMcf and 1.8 MBbls per day.

         St. Mary granted 3,088 acres of new leases on its fee lands during 1997
and received associated cash bonus payments of $757,000.  New leases provide the
Company with a 25% royalty on all production and the option to participate as up
to a 25% working  interest owner.  Accordingly,  as in the case of the discovery
and confirmation  well at South Horseshoe Bayou, St. Mary bears 25% of the costs
but  receives  approximately  40% of the  revenues.  In 1997 St.  Mary opened an
exploration  office in  Lafayette,  Louisiana  as part of its strategy to expand
activities in the transition zone of the Gulf Coast.

         St. Mary's historical presence in southern  Louisiana,  its established
network of industry  relationships and its extensive  technical  database on the
area have enabled the Company to assemble an inventory of large-target prospects
in the south Louisiana region.

         South Horseshoe Bayou Prospect Discovery.  In February 1997 the Company
announced a  significant  deep gas discovery on its fee lands in St. Mary Parish
at the St. Mary Land & Exploration  No. 2 well. This well was completed in sands
below 17,300 feet and produced over six Bcf of gas during 1997. In January  1998
a confirmation well, the St. Mary Land & Exploration No. 3, was completed in the
same  interval  at a rate of over  35 MMcf  per  day.  The  Company  expects  to
recomplete  the No. 2 well in a lower pay zone at  approximately  17,900 feet in
April 1998.  The Company  believes  that an  additional  well may be required to
evaluate an adjacent but separate fault block situated  immediately to the north
of the two existing wells. St. Mary will evaluate this prospect during 1998 with
the goal of  drilling  a well in late  1998 or  early  1999.  See  "Large-Target
Exploration Projects."

         Roanoke  Prospect   Discovery.   St.  Mary  and  its  partners  control
approximately  8,800  gross acres at the Roanoke  Prospect  in  Jefferson  Davis
Parish through a combination of seismic  permits,  options and leases.  St. Mary
holds a 33.3 %  working  interest  in the  prospect  area.  The  Roanoke  Field,
originally discovered in 1934, has produced over 25 MMBbls of oil and 100 Bcf of
gas.  This is a  complexly  faulted  salt dome field and was  considered  by the
Company to be an excellent  candidate for re-evaluation using modern 3-D seismic
imaging to identify potential by-passed pays and untested fault blocks.

         The first  exploratory  test at Roanoke was  successfully  completed in
September 1997 as a discovery in the Frio  formation and is currently  producing
over 7.0 MMcf per day. In 1998 St. Mary and its  partners  plan to test a second
prospect at Roanoke targeting the Hackberry formation on a separate fault block.
See "Large-Target Exploration Projects."

         Atchafalaya  Bay  Prospect.  In March 1997 the  Company and its partner
acquired  seven tracts  (2,845  gross acres) in a Louisiana  state lease sale in
Atchafalaya  Bay.  The leases are located  approximately  two miles south of the
Company's  1997  discovery at South  Horseshoe  Bayou and lie in water depths of
less than five feet in the delta of Atchafalaya Bay.

         St.  Mary holds a 40%  working  interest  in this  large,  3-D  defined
prospect below 16,000 feet that targets the same sands found to be productive at
South Horseshoe  Bayou.  The Company expects that several wells will be required
to fully test the prospect due to its size and configuration.

         An initial  exploratory  test at Atchafalaya was commenced in September
1997 but experienced serious drilling problems in October when an over-pressured
sand was  penetrated  below  12,000  feet.  The  initial  well was  plugged  and
abandoned due to these drilling  problems and a replacement  well was started in
November  1997.  The current well is drilling below 16,000 feet and is scheduled
to reach total depth of approximately  19,000 feet in April 1998. If successful,
the Company  estimates  that the  initial  well could be  connected  to pipeline
facilities  within  approximately  60  days  of  completion  of  the  well.  See
"Large-Target Exploration Projects."

         Belle Bayou Prospects. A series of four separate deep gas prospect have
been identified on the eastern portion of the Company's fee lands on the western
flank of the Belle Isle Field.  St. Mary has a 12.5% working  interest and a 25%
royalty interest in the first exploratory test that commenced  drilling in March
1998. See "Large-Target Exploration Projects."

                                      -9-
<PAGE>

         Patterson  Prospect.   The  Company's  Patterson  prospect  is  located
approximately 20 miles north of the Company's fee lands in St. Mary Parish.  St.
Mary holds a 25% working interest in leases and options  totaling  approximately
5,573 acres in the prospect area which lies within a major  east-west  producing
trend between the Garden City and Patterson Fields. An unsuccessful  19,000-foot
test was drilled in 1995 based on 2-D seismic data and existing well control. In
order to further  evaluate  this  prospect,  in 1997 St.  Mary and its  partners
purchased  20 square miles of a regional  3-D seismic  survey.  In 1998 St. Mary
plans  to  reenter  and  sidetrack  the  existing  well to test a newly  defined
prospect targeting the MA-3 and MA-7 formations.  See "Large-Target  Exploration
Projects."

         ArkLaTex  Region.  The  Company's  operations  in the ArkLaTex area are
managed by the Company's 12-person office in Shreveport, Louisiana. The ArkLaTex
region accounted for 21.2% of the Company's  estimated net proved reserves as of
December 31, 1997 or 56.2 BCFE (81% proved developed and 90% gas). The Company's
1998  capital  budget  provides  $8.1 for  additional  drilling,  primarily  for
continued development at the Haynesville and Box Church Fields.

         In 1992 the Company  acquired the ArkLaTex oil and gas properties of T.
L. James & Company,  Inc. as well as rights to over 6,000  miles of  proprietary
2-D seismic data in the region.  St. Mary's  holdings in the ArkLaTex region are
comprised  of interests  in  approximately  426  producing  wells,  including 58
Company-operated  wells, and interests in leases totaling  approximately  45,600
gross acres and mineral servitudes  totaling  approximately  15,600 gross acres.
Since 1992, the Company has completed six additional  acquisitions  of producing
properties in the region  totaling  $10.3  million and has  undertaken an active
program of additional development and exploration.

         In 1994 and 1995 the  Company  extended  the Bayou  D'Arbonne  Field in
Union  Parish,  Louisiana  with six  successful  wells in the Cotton Valley sand
formation.  Since the Company's discovery at the Haynesville Field in Clairborne
Parish,  Louisiana  in  1995,  St.  Mary  has  drilled  or  participated  in ten
successful wells in the Haynesville  formation and plans to drill or participate
in seven additional wells in the field during 1998.

         The   Company   and  its  partner   acquired   the  Box  Church   Field
(approximately  2,112 gross acres) in Limestone  County,  Texas in four separate
transactions  during 1995 and 1996. The Company's net  acquisition  cost totaled
$2.6 million, and the Company operates and holds an average 58% working interest
in  three  units  comprising  this  field.  During  1996,  the  Company  made  a
significant discovery in the Box Church Field in the Upper and Lower Travis Peak
formations   (approximately   7,500  feet)  and  the  Cotton  Valley   formation
(approximately  9,000 feet).  This  discovery  resulted at year-end  1996 in the
addition  of 26.4 Bcf of  estimated  net  proved  reserves,  representing  a 35%
increase  in the  Company's  gas  reserves.  At the  end of 1997  there  were 18
producing  wells in the Box Church Field and an additional  three wells awaiting
completion.  The Company's development program increased gross production at the
Box Church Field from approximately 2.5 MMcf per day when the field was acquired
to over 22 MMcf per day in  December  1997.  The  Company  plans  to drill  four
additional wells at Box Church in 1998.

         Williston Basin Region. The Company's operations in the Williston Basin
are conducted through Panterra  Petroleum,  a general partnership formed in June
1991. The Company holds a 74% general  partnership  interest in Panterra and the
managing partner,  Nance Petroleum  Corporation ("Nance Petroleum"),  owns a 26%
interest.  Nance Petroleum's  principal activity is the management of Panterra's
interest  in the  Williston  Basin.  All of St.  Mary's  and  Nance  Petroleum's
activities  in  the  Williston  Basin  are  conducted  through  Panterra,  which
currently  owns  interests in 63 fields within the basin's core  producing  area
including 108,000 gross acres, 68 Panterra-operated wells and 175 wells operated
by other parties.

                                      -10-
<PAGE>

         The  Williston  Basin  region  accounted  for  12.7%  of the  Company's
estimated  net proved  reserves as of December 31, 1997 or 33.6 BCFE (94% proved
developed and 89% oil). St. Mary has budgeted  approximately $4.1 million as its
share of Panterra's 1998  development and  exploration  program,  which includes
three Panterra-operated wells.

         The Company's  exploration and development  activities in the Williston
Basin  have  focused  on  the  application  of 3-D  seismic  data  to  delineate
structural and  stratigraphic  features  which were not  previously  discernible
using  conventional 2-D seismic.  Panterra has conducted over 45 square miles of
3-D seismic surveys covering  selected  portions of the North Bainville Field in
Roosevelt County, Montana; the Brush Lake Field in Sheridan County, Montana; the
Nameless  Field in McKenzie  County,  North  Dakota and the Mondak  Field on the
Montana/North  Dakota border. These surveys have generated a series of prospects
and have  resulted  in the  drilling  of 13  Panterra-operated  development  and
exploration wells since 1991 with a 100% success rate.

         St. Mary  plans to  evaluate  additional  opportunities  at  the  North
Bainville,  Brush Lake and Mondak  Fields  and to build  its prospect  inventory
during 1998.

         Permian Basin Region. The Permian Basin of New Mexico and west Texas is
the Company's newest area of concentration. Management believes that its Permian
Basin operations  provide St. Mary with a solid base of long lived oil reserves,
promising  longer-term  exploration and development  prospects and the potential
for secondary recovery projects. The Company established a presence in the basin
in 1995 through the  acquisition  of a 21.2% working  interest in a top lease in
Ward  and  Winkler  Counties,  Texas  which  is  believed  to  have  significant
development and exploration potential.  The Company expanded its holdings in the
basin  during  1996 with the  acquisition  of a 90%  interest  in the  producing
properties of Siete Oil & Gas  Corporation.  The Permian Basin region  accounted
for 10.2% of the Company's estimated net proved reserves as of December 31, 1997
or 27.0 BCFE (91% proved developed and 82% oil).

         Ward Estes.  The Company  acquired a 21.2% interest in the top lease in
the Ward Estes North Field in Ward County,  Texas for $1.7 million in 1995.  The
top lease covers 30,450  contiguous  acres and becomes  effective in August 2000
when the existing base lease expires.  Rights to all remaining  production  from
the leasehold  will transfer to St. Mary and its partners in August 2000.  Wells
covered by the base lease  currently  produce in excess of 6,000  barrels of oil
per day from relatively  shallow formations and are expected to have significant
remaining reserves when the base lease expires.

         The Company believes that the Ward Estes top lease provides it with the
attractive  combination of a low-risk acquisition of long-lived oil reserves and
a long-term  exploration and development project. St. Mary and its partners have
initiated  discussions to determine whether the remaining two and one-half years
of the base lease can be acquired from the existing holder.  However,  there can
be no assurance that these  negotiations  will prove successful or that St. Mary
will gain access to the property  prior to the  expiration  of the base lease in
August 2000. See "Large- Target Exploration Projects."

         Siete  Properties.  In 1996 the Company  completed the acquisition of a
90% interest in the oil and gas  properties of Siete Oil & Gas  Corporation  for
$10.0 million. The acquisition included approximately 150 wells in southeast New
Mexico and west Texas producing from the Yates/Queen,  Delaware and Bone Springs
sands at  depths of  between  3,500 and 7,500  feet  which are  operated  by the
Company's 10% partner.  The acquired reserves were approximately 80% oil and had
a reserve life of approximately 15 years. During the balance of 1996 and in 1997
the Company completed a series of follow-on acquisitions of smaller interests in
the Siete properties which totaled $4.6 million.

                                      -11-
<PAGE>

         In 1998 St. Mary plans to invest  approximately $6.8 million in several
projects including the expansion of a successful pilot waterflood project at the
Parkway Field and the  commencement of a waterflood of the Shugart Field,  which
were part of the Siete acquisition made in 1996.

         Large-Target  Exploration  Projects.  The Company invests approximately
15%  to  20%  of  its  annual  capital  budget  in   longer-term,   higher-risk,
high-potential  exploration projects.  During the past several years the Company
has  assembled  an inventory of large  potential  projects in various  stages of
development  which have the  potential  to  materially  increase  the  Company's
reserves.  The  Company's  strategy is to maintain a pipeline of seven to ten of
these high-potential prospects and to test four or more targets each year, while
furthering the development of early-stage projects and continuing the evaluation
of potential new exploration prospects.

         The Company generally seeks to develop large-target  prospects by using
its comprehensive  base of geological,  geophysical,  engineering and production
experience  in each of its focus  areas.  The  large-target  projects  typically
require  relatively  long  lead  times  before a well is  commenced  in order to
develop proprietary geologic concepts,  assemble leasehold positions and acquire
and fully  evaluate  3-D  seismic or other  data.  The  Company  seeks  wherever
appropriate to apply the latest  technology,  including 3-D seismic imaging,  in
its  prospect  development  and  evaluation  so as to  mitigate a portion of the
inherently higher risk of these exploration projects.  In addition,  the Company
seeks to invest in a  diversified  mix of  exploration  projects  and  generally
limits its capital exposure by  participating  with other  experienced  industry
partners.

         The  following  table  summarizes  the  Company's  active  large-target
exploration projects. See also "Properties."

International Operations

         In 1997 the Company  completed the sale or disposition of its remaining
international  investments,  with the  exception of minor  working  interests in
properties in Canada,  which  represented less than one percent of the Company's
estimated proved reserves at December 31, 1997.

                                      -12-

         Russian Joint Venture. In February 1997, the Company sold its interests
in its  Russian  joint  venture to Khanty  Mansiysk  Oil  Corporation  ("KMOC"),
formerly known as Ural Petroleum  Corporation for  consideration  totaling $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 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 and the  Company  has the right,  subject to certain
conditions,  to require KMOC to purchase the 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.

         Trinidad  and  Tobago.  In 1997  the  Company  relinquished  its  7.47%
reversionary  interest in a  281,506-acre  onshore  exploration  and  production
license in the Caroni Basin of Trinidad and Tobago.

Key Relationships

         The Company cultivates strategic  partnerships with independent oil and
gas  operators  having  region-specific  experience  and  specialized  technical
skills.  The  Company's  strategy is to serve as operator  or  alternatively  to
maintain a majority  interest in such  ventures  to ensure that it can  exercise
significant influence over development and exploration  activities.  In addition
the  Company   seeks   industry   partners  who  are  willing  to  co-invest  on
substantially  the  same  basis  as the  Company.  For  example,  the  Company's
operations in the Williston  Basin are conducted  through  Panterra in which St.
Mary holds a 74% general partnership interest.  The managing partner of Panterra
is Nance  Petroleum  Corporation,  the  principal  of which has over 25 years of
experience in the Williston Basin.

Acquisitions

         The Company's  strategy is to make selective niche  acquisitions of oil
and gas  properties  within its core operating  areas in the United States.  The
Company seeks to acquire  properties  that  complement its existing  operations,
offer  economies  of scale  and  provide  further  development  and  exploration
opportunities based on proprietary geologic concepts or advanced well completion
techniques.   Management  believes  that  the  Company's  success  in  acquiring
attractively priced and  under-exploited  properties has resulted from its focus
on smaller,  negotiated  transactions where the Company has specialized geologic
knowledge or operating experience.

         Although the Company periodically  evaluates large acquisition packages
offered in  competitive  bid or auction  formats,  the Company has  continued to
emphasize  acquisitions  having values of less than $10 million which  generally
attract less competition and where the Company's technical expertise,  financial
flexibility  and structuring  experience  affords a competitive  advantage.  The
Company seeks  acquisitions  that offer  additional  development and exploration
opportunities such as its series of acquisitions in the Box Church Field of east
Texas during 1995 and 1996.  During 1996 and 1997, the Company  purchased eleven
parcels for $21.0 million and five parcels for $27.3 million,  respectively. For
1998 the Company has budgeted $20 million for property acquisitions.

Reserves

         At December 31, 1997,  Ryder Scott,  independent  petroleum  engineers,
evaluated properties representing approximately 82% of the Company's total PV-10
Value and the Company  evaluated  the  remainder.  The PV-10 Values shown in the
following  table are not intended to represent  the current  market value of the
estimated net proved oil and gas reserves  owned by the Company.  Neither prices
nor costs  have been  escalated,  but  prices  include  the  effects  of hedging
contracts.

Productive Wells

         The  following  table sets forth  information  regarding  the number of
productive  wells in which the Company  held a working  interest at December 31,
1997. Productive wells are either producing wells or wells capable of commercial
production  although  currently  shut in.  One or more  completions  in the same
borehole are counted as one well. A well is  categorized  under state  reporting
regulations  as an oil well or a gas  well  based  upon the  ratio of gas to oil
produced when it first  commenced  production,  and such  designation may not be
indicative of current production.

     (1)  Developed  acreage  is acreage  assigned  to  producing  wells for the
          spacing unit of the producing formation.  Developed acreage in certain
          of the Company's  properties  that include  multiple  formations  with
          different well spacing requirements may be considered  undeveloped for
          certain  formations,  but have only been included as developed acreage
          in the presentation above.
     (2)  Undeveloped  acreage  is lease  acreage  on which  wells have not been
          drilled or completed to a point that would  permit the  production  of
          commercial  quantities  of oil  and gas  regardless  of  whether  such
          acreage contains estimated net proved reserves.

          45,919 gross acres in Utah.

Non-Oil and Gas Activities

         Summo  Minerals.  The Company,  through a subsidiary,  owns 9.9 million
shares or 37% of Summo Minerals Corporation  ("Summo"),  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 addition,  the Company owns 616,090  warrants and options to purchase  common
shares,  exercisable  at a price of Cdn $1.10 and which expire October 17, 1998.
Summo's  common shares are listed on the Toronto stock exchange under the symbol
"SMA".  The Company's  investment in Summo had a market value of $1.8 million at
December 31, 1997.

                                      -16-
<PAGE>

         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 senior debt financing in return for a 45% interest in
the new company.  The agreement is subject to certain conditions,  including the
final  resolution of  regulatory  approvals  and  finalization  of the necessary
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  ("BLM") when the Project was initially  approved.  A
decision  from the Interior  Board of Land  Appeals  ("IBLA") 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
December 31, 1997, $2.1 million was  outstanding  under this loan. 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.  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.

Competition

         Competition in the oil and gas business is intense,  particularly  with
respect to the acquisition of producing  properties,  proved undeveloped acreage
and  leases.  Major  and  independent  oil and gas  companies  actively  bid for
desirable oil and gas  properties  and for the equipment and labor  required for
their operation and development.  The Company believes that the locations of its
leasehold acreage, its exploration, drilling and production capabilities and the
experience of its management and that of its industry partners  generally enable
the Company to compete effectively. Many of the Company's competitors,  however,
have financial  resources and exploration,  development and acquisition  budgets
that  are  substantially  greater  than  those of the  Company,  and  these  may
adversely  affect the  Company's  ability to  compete,  particularly  in regions
outside of the Company's principal producing areas. Because of this competition,
there can be no  assurance  that the Company will be  successful  in finding and
acquiring producing properties and development and exploration  prospects at its
planned capital funding levels.

Markets and Major Customers

         During 1997 two customers individually accounted for 10.6% and 10.2% of
the  Company's  total  oil and gas  production  revenue.  Sales  to one of these
customers constituted 17.3% of total 1996 oil and gas production revenue.  There
were no sales to individual customers  constituting 10% or more of total oil and
gas production revenue during 1995.

Government Regulations

         The Company's  business is subject to various federal,  state and local
laws and  governmental  regulations  that may be  changed  from  time to time in
response to economic or  political  conditions.  Matters  subject to  regulation
include  discharge  permits for drilling  operations,  drilling  bonds,  reports
concerning  operations,  the  spacing  of  wells,  unitization  and  pooling  of
properties, taxation and environmental protection. From time to time, regulatory
agencies  have  imposed  price   controls  and   limitations  on  production  by
restricting  the  rate of flow of oil and  gas  wells  below  actual  production
capacity in order to conserve supplies of oil and gas.

         The  Company's  operations  could  result  in  liability  for  personal
injuries,  property  damage,  oil  spills,  discharge  of  hazardous  materials,
remediation  and clean-up  costs and other  environmental  damages.  The Company
could be liable for environmental damages caused by previous property owners. As
a result,  substantial liabilities to third parties or governmental entities may
be incurred,  and the payment of such liabilities  could have a material adverse
effect on the  Company's  financial  condition  and results of  operations.  The
Company  maintains  insurance  coverage for its  operations,  including  limited
coverage for sudden  environmental  damages, but does not believe that insurance
coverage  for  environmental  damages  that  occur over time is  available  at a
reasonable cost. Moreover,  the Company does not believe that insurance coverage
for the full potential  liability  that could be caused by sudden  environmental
damages is  available  at a  reasonable  cost.  Accordingly,  the Company may be
subject to liability or may lose  substantial  portions of its properties in the
event of certain  environmental  damages.  The Company  could incur  substantial
costs to comply with environmental laws and regulations.

         The Oil  Pollution  Act of 1990  imposes a variety  of  regulations  on
"responsible   parties"   related  to  the   prevention   of  oil  spills.   The
implementation  of new, or the modification of existing,  environmental  laws or
regulations, including regulations promulgated pursuant to the Oil Pollution Act
of 1990, could have a material adverse impact on the Company.

         The recent trend toward stricter standards in environmental legislation
and  regulation  is likely  to  continue.  For  instance,  legislation  has been
introduced in Congress that would reclassify certain  exploration and production
wastes as "hazardous wastes" which would make the reclassified wastes subject to
much more  stringent  handling,  disposal  and  clean-up  requirements.  If such
legislation  were enacted,  it could have a significant  impact on the operating
costs  of the  Company,  as  well  as the  oil  and  gas  industry  in  general.
Initiatives  to further  regulate  the  disposal  of oil and gas wastes are also
pending in certain states,  and these various  initiatives  could have a similar
impact on the Company.

Title to Properties

         Substantially  all of the Company's working interests are held pursuant
to leases from third parties.  A title opinion is usually  obtained prior to the
commencement  of drilling  operations  on  properties.  The Company has obtained
title opinions or conducted a thorough title review on substantially  all of its
producing  properties  and  believes  that  it has  satisfactory  title  to such
properties in accordance  with standards  generally  accepted in the oil and gas
industry.  The Company's  properties are subject to customary royalty interests,
liens for current  taxes and other  burdens  which the  Company  believes do not
materially  interfere  with the use of or affect  the value of such  properties.
Substantially  all of the  Company's  oil and gas  properties  are  mortgaged to
secure  borrowings under the Company's credit  facilities.  The Company performs
only a minimal title investigation before acquiring undeveloped properties.

Operational Hazards and Insurance

         The oil  and gas  business  involves  a  variety  of  operating  risks,
including fire, explosions, blow-outs, pipe failure, casing collapse, abnormally
pressured  formations and environmental  hazards such as oil spills,  gas leaks,
ruptures and  discharges  of toxic gases,  the  occurrence of any of which could
result in  substantial  losses to the  Company  due to injury  and loss of life,
severe damage to and destruction of property,  natural  resources and equipment,
pollution and other environmental damage, clean-up responsibilities,  regulatory
investigation  and  penalties  and  suspension  of  operations.  The Company and
operators of properties in which it has an interest  maintain  insurance against
some, but not all, potential risks; however, there can be no assurance that such
insurance  will be adequate to cover any losses or exposure for  liability.  The
occurrence  of a  significant  unfavorable  event not fully covered by insurance
could have a material  adverse effect on the Company's  financial  condition and
results of operations. Furthermore, the Company cannot predict whether insurance
will continue to be available at a reasonable cost or at all.

Employees and Office Space

         As of December 31, 1997, the Company had 103 full-time employees.  None
of the Company's employees is subject to a collective bargaining agreement.  The
Company  considers  its  relations  with its  employees to be good.  The Company
leases approximately 34,500 square feet of office space in Denver, Colorado, for
its executive offices, of which 7,200 square feet is subleased. The Company also
leases  approximately  15,000  square feet of office  space in Tulsa,  Oklahoma,
approximately  7,300 square feet of office space in  Shreveport,  Louisiana  and
approximately 500 square feet in Lafayette, Louisiana. The Company believes that
its current facilities are adequate.

     (1)  EBITDA is defined as income before interest income and expense, income
          taxes,  depreciation,  depletion,  amortization,  and  gain on sale of
          discontinued  operations.  EBITDA is a financial measure commonly used
          for the  Company's  industry and should not be considered in isolation
          or as a  substitute  for net income,  cash flow  provided by operating
          activities  or other income or cash flow data  prepared in  accordance
          with  generally  accepted  accounting  principles or as a measure of a
          company's  profitability  or liquidity.  Because EBITDA excludes some,
          but  not  all,  items  that  affect  net  income  and may  vary  among
          companies,  the  EBITDA  presented  above  may  not be  comparable  to
          similarly titled measures of other companies.

ITEM 7.  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 operation.  Effective February 12, 1997, the Company sold its Russian
joint venture.

         The  Company  receives   significant  royalty  income  from  its  south
Louisiana fee lands.  Royalty  revenues  from the fee lands were $8.8,  $8.1 and
$5.5 million for the years 1997, 1996 and 1995, respectively. 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. The Company owns a 25% working  interest and 22% royalty  interest in this
field for a combined net revenue interest of approximately  40%. 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.  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 $4.6 million during 1997 and 1996.  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 October 1996, the Company acquired additional interests in its Elk
City Field located in Oklahoma from Sonat Exploration  Company for $5.7 million.
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.

                                      -25-

         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.

         The  Company  closed the sale of  2,000,000  shares of common  stock at
$25.00 per share in February 1997 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,  and in December  1996,  the Company  sold its  interests  in
Wyoming for $2.9 million,  both 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 14% of
its estimated  1998 gas  production at an average fixed price of $2.11 per MMBtu
and  approximately  4% of its estimated  1998 oil production at an average fixed
price of $18.18 per Bbl.  The Company has also  purchased  options  resulting in
price collars on approximately 7% of the Company's estimated 1998 gas production
with price  ceilings  between $2.55 and $3.00 per MMBtu and price floors between
$1.95 and  $2.00 per MMBtu as well as  options  resulting  in price  collars  on
approximately  5% of the  Company's  estimated  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.

     (1)  Includes the effects of the Company's hedging activities.

         Oil and Gas  Production  Revenues.  Oil  and  gas  production  revenues
increased  $19.0  million,  or 33% to $75.8  million in 1997  compared  to $56.8
million in 1996. Oil production  volumes remained constant between 1997 and 1996
while gas production volumes increased 47% in 1997 compared to 1996. Average net
daily  production  reached 13.7 MBOE in 1997 compared to 10.3 MBOE in 1996. This
production  increase  resulted from new  properties  acquired and drilled during
1997. Major acquisitions  included the Southwest Mayfield  properties  purchased


                                      -27-
<PAGE>

from Conoco,  the  acquisition  of Louisiana  properties  from Henry  Production
Company  and  the  additional  interests  purchased  in  the  Siete  properties.
Successful  drilling  results  in the Box  Church  Field in Texas  and the South
Horseshoe  Bayou  prospect  in  south  Louisiana  also  contributed  to the 1997
production  increase.  These  production  increases were partially offset by the
sale of the Company's south Texas non-operated properties.  The average realized
oil price for 1997  increased  1% to $18.87 per Bbl,  while  realized gas prices
increased 4% to $2.33 per Mcf, from their  respective  1996 levels.  The Company
hedged  approximately  16% of its oil  production  for  1997 or 185  MBbls at an
average NYMEX price of $18.36.  The Company realized a $293,000  decrease in oil
revenue or $.25 per Bbl for 1997 on these  contracts  compared to a $2.6 million
decrease or $2.20 per Bbl in 1996.  The Company  also hedged 27% of its 1997 gas
production or 6,687,000 MMBtu at an average indexed price of $2.06.  The Company
realized a $2.9  million  decrease in gas revenues or $.13 per Mcf for 1997 from
these hedge  contracts  compared to a $1.65 million  decrease or $.11 per Mcf in
1996.

         Oil and gas production  revenues  increased  $20.2  million,  or 55% to
$56.8 million in 1996 compared to $36.6 million in 1995. Oil production  volumes
increased 14% and gas production volumes increased 25% in 1996 compared to 1995.
Average net daily  production  reached 10.3 MBOE in 1996 compared to 8.5 MBOE in
1995. This production increase resulted from new properties acquired and drilled
during  1996,  most  notably the  acquisitions  of the Siete  properties  in the
Permian  Basin and the  additional  interests in the Elk City Field in Oklahoma.
The  average  realized  oil price for 1996  increased  14% to $18.64 per Bbl and
realized gas prices  increased 42% to $2.23 per Mcf, from their  respective 1995
levels.  The Company hedged  approximately 70% of its oil production for 1996 or
842 MBbls at an average  NYMEX  price of  $18.92.  The  Company  realized a $2.6
million  decrease  in oil  revenue or $2.20 per Bbl for 1996 on these  contracts
compared to a $131,000 decrease or $.13 per Bbl in 1995. The Company also hedged
23% of its 1996 gas  production or 3,651,000  MMBtu at an average NYMEX price of
$2.00. The Company realized a $1.65 million decrease in gas revenues or $.11 per
Mcf for 1996 from these hedge contracts compared to a $121,000 increase in 1995.

         Oil and Gas Production  Costs.  Oil and gas production costs consist of
lease operating expense and production  taxes.  Total production costs increased
$2.4  million,  or 18% in 1997 to $15.3  million  compared with $12.9 million in
1996. However,  total oil and gas production costs per BOE declined 11% to $3.05
in 1997  compared  to  $3.41  per BOE in  1996.  Oil  and gas  production  costs
increased  $2.3  million,  or 21% in 1996 to $12.9  million  compared with $10.6
million in 1995.  However,  total oil and gas production  costs per BOE declined
slightly to $3.41 in 1996 from $3.42 per BOE in 1995.

         Depreciation,  Depletion,  Amortization  and Impairment.  Depreciation,
depletion and amortization  expense ("DD&A")  increased $5.7 million,  or 44% to
$18.4  million in 1997  compared  with  $12.7  million  in 1996.  This  increase
resulted from new properties  acquired and drilled in 1997. DD&A expense per BOE
increased 9% to $3.67 in 1997  compared to $3.37 in 1996 due to higher  drilling
and  acquisition  costs per BOE.  Impairment  of proved  oil and gas  properties
increased  $4.8 million to $5.2 million in 1997  compared with $408,000 in 1996.
These  charges  resulted  from a  decline  in the  value  of the  Company's  oil
properties in the  Williston  Basin due to lower oil prices at year-end 1997 and
the  under-performance of a marginal field, as well as the  under-performance of
several gas fields in the Mid-Continent region.

         Depreciation,  depletion and  amortization  expense  increased to $12.7
million in 1996  compared  with $10.2  million in 1995 and DD&A  expense per BOE
increased 3% to $3.37 in 1996  compared to $3.28 in 1995.  Impairment  of proved
oil and gas  properties  decreased  $2.3 million to $408,000 in 1996 compared to
$2.7 million in 1995.  The 1995  impairment  provision  included  effects of the
adoption of SFAS No. 121 as of October 1, 1995 which  resulted in an  additional
impairment charge for proved properties of $1.0 million in the fourth quarter of
1995.

                                      -28-

         Abandonment and impairment of unproved properties increased $608,000 or
41% to $2.1 million in 1997  compared to $1.5 million in 1996 due to  additional
impairments taken during 1997, partially offset by fewer abandonments of expired
leases.  Abandonment and impairment of unproved properties decreased $890,000 or
38% to $1.5 million in 1996 compared to $2.4 million in 1995.

         Exploration.  Exploration expense decreased $1.3 million or 16% to $6.8
million for 1997  compared  with $8.2  million in 1996  primarily as a result of
better  exploratory  drilling  results  in 1997  compared  to 1996.  Exploration
expense  increased  $3.1 million or 61% to $8.2 million in 1996 compared to $5.1
million  in 1995  due to  increased  geophysical  activity  in 1996  and  better
exploratory drilling results in 1995.

         General and  Administrative.  General and administrative  expenses were
unchanged  at $7.6  million for 1997 from 1996.  Increased  compensation  costs,
charitable  contributions  and insurance  premium costs in 1997 were offset by a
$1.4  million  decrease  in the  expense  associated  with the  Company's  Stock
Appreciation Rights ("SAR") plan. General and administrative  expenses increased
$2.3 million or 43% to $7.6 million in 1996 compared to $5.3 million in 1995 due
to higher compensation  costs,  professional fees and a $1.3 million increase in
the expense associated with the Company's SAR plan.

         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  $204,000 to $282,000 in 1997 compared with
1996,  primarily due to legal expenses  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. This expense declined $74,000 to
$78,000 in 1996 compared with 1995 because insurance  proceeds were recovered in
1996 on a previous settlement.

         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.  The equity in the net income (loss) of
the  Russian  joint  venture  was  $201,000  in 1997,  $1.7  million in 1996 and
$(322,000) in 1995. As discussed under Outlook, the Company sold this investment
in February 1997 resulting in a partial year of equity income  recorded in 1997.
The large  increase  in 1996 net  income was due to higher  oil  production  and
prices.

         Equity in Loss of Summo Minerals Corporation.  The Company accounts for
this investment under the equity method and includes its share of Summo's income
or loss in its  results of  operations.  The equity in the net loss of Summo was
$526,000 in 1997,  $457,000 in 1996 and $257,000 in 1995.  Increased  losses are
due to general and  administrative  expenses  associated  with the  expansion of
Summo's Denver office  beginning in 1996.  The Company's  ownership in Summo was
37% in 1997, 49% in 1996 and 51% in 1995.

         Non-Operating  Income and Expense. Net interest and other non-operating
expense  decreased  $1.9 million to $99,000 in 1997 due to the  reduction of the
Company's  debt  with the  proceeds  of the sale of  common  stock in the  first
quarter of 1997.  Net interest and other  non-operating  expense  increased $1.1
million  to $2.0  million  in 1996  compared  to  $896,000  in 1995  because  of
additional  interest  expense  associated with higher debt levels resulting from
increased  exploration,  development  and  property  acquisition  activity.  Net
interest and other non-operating  expense increased $371,000 to $896,000 in 1995
because of the  interest  expense  associated  with  higher  debt levels and the
Company's increased Panterra ownership.

         Income  Taxes.  Income tax expense  was $12.3  million in 1997 and $5.3
million in 1996, resulting in effective tax rates of 35% and 34%,  respectively.
This expense reflects higher net income from continuing operations before income
taxes for each year  compared to the  previous  year,  offset  partially  by the
utilization  of Section 29 tax credits.  Income taxes provided a net tax benefit
of $723,000 for 1995 with the utilization of capital loss carryovers and Section
29 tax credits. State tax expense was $1.6 million in 1997, $700,000 in 1996 and
$396,000 in 1995.  1997 and 1996 Louisiana taxes  increased  significantly  as a
result of higher  Louisiana net income,  primarily  from royalty  income in both
1997 and 1996, and working  interest  income from South  Horseshoe Bayou and the
Henry Production Company acquisition during 1997.

                                      -29-

         Net  Income.  Net income for 1997  increased  $12.8  million or 124% to
$23.1  million  compared to $10.3 million in 1996. A 47% increase in gas volumes
and modest  increases in oil and gas prices resulted in a $19.0 million increase
in oil and gas  production  revenues.  A $9.7  million  gain on the  sale of the
Company's  Russian  joint  venture,  a $4.2  million  gain  on the  sale  of the
Company's  south  Texas  properties  and a $700,000  lease  bonus  received  for
exploration on the Company's fee lands  contributed to total operating  revenues
of $91.0 million.  These revenues were partially offset by the higher production
expenses and DD&A associated with increased  production  volumes, a $4.8 million
increase in  impairment  of proved  properties  and a $325,000  loss from equity
investees.  The  Company  also  realized  a  $488,000  gain  from  the  sale  of
discontinued real estate in 1997, compared to a gain of $159,000 in 1996.

         Net income for 1996  increased  $8.6  million or 492% to $10.3  million
compared  to $1.7  million in 1995 with  higher  production  volumes  and prices
resulting in a $20.2 million increase in oil and gas production  revenues.  This
was partially offset by the associated  higher  production  expenses and DD&A, a
$3.1 million  increase in  exploration  expense and a $2.3  million  increase in
general and  administrative  expenses.  The Company also realized a $2.3 million
gain on sale of producing  properties  in 1996  compared to $1.3 million in 1995
and recorded  $1.7 million in net income from its Russian  joint venture in 1996
compared to a loss of $322,000 in 1995.

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. In 1997, the Company  financed a large portion of its
exploration and  development  programs with the proceeds from the sale of common
stock. 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  $18.9  million  or 78% to $43.1  million  in 1997  compared  to $24.2
million in 1996. The  significant  increase in receipts for oil and gas revenues
were  partially  offset by higher  production  costs and  increased  exploration
expenses.  Net cash  provided by  operating  activities  increased  37% to $24.2
million in 1996 compared to $17.7 million in 1995 also due to increased revenues
partially offset by higher production costs, general and administrative expenses
and exploration expenses.

         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.

         Net cash used in investing activities increased $22.3 million or 49% to
$67.5 million compared to $45.2 million in 1996. This increase was primarily due
to  significantly  increased  capital  expenditures  for the Company's  drilling
programs,  increased expenditures for acquisitions of oil and gas properties and
additional investment in and loans to Summo, partially offset by $7.7 million of
proceeds  from  the sale of oil and gas  properties  and $ 5.6  million  in cash
received  from the sale of the  Company's  Russian  joint  venture.  Total  1997
capital  expenditures,   including  acquisitions  of  oil  and  gas  properties,
increased  $33.0  million or 68% to $81.5  million  compared to $48.5 million in
1996.

<PAGE>

         Net cash used in investing activities increased 37% to $45.2 million in
1996  compared with $33.0  million in 1995  primarily  due to increased  capital
expenditures and acquisition of oil and gas properties  partially offset by $3.1
million  in cash  received  as a result of the  purchase  of the  remaining  35%
interest in St. Mary  Operating  Company and $3.1  million in proceeds  from the
sale  of  oil  and  gas  properties.   Total  capital  expenditures,   including
acquisitions of oil and gas properties, in 1996 increased $17.7 million to $48.5
million compared to $30.8 million in 1995 due to increased drilling activity and
$21.0 million of reserve acquisitions compared to $8.1 million spent in 1995.

         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 for tax purposes.  Gains or losses for
tax  purposes  are  recognized  by  amortization  of the  lower tax basis of the
property  throughout  its  remaining  life or when the new  property  is sold or
abandoned.

         Net cash  provided by financing  activities  increased  $5.5 million to
$28.1 million  compared to $22.6  million in 1996.  The Company  received  $51.2
million from the sale of common stock in the first quarter of 1997 and had a net
reduction of borrowings of $21.0 million in 1997. Net cash provided by financing
activities  increased  $15.6  million to $22.6  million in 1996 compared to $7.0
million in 1995.  The Company  borrowed  funds in 1996 for the expanded  capital
expenditure  programs  and  reserve  acquisitions.  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,  resulting in dividends paid
in 1997 of $2.1 million compared to $1.4 million in 1996 and 1995.

         The Company had $7.1 million in cash and cash  equivalents  and working
capital of $9.6 million as of December 31, 1997 compared to $3.3 million of cash
and cash  equivalents and working capital of $13.9 million at December 31, 1996.
This decrease in working capital  resulted from a net increase in trade accounts
payable over oil and gas receivables due to increased  drilling activity and the
1997 sale of the  Company's  Russian  joint  venture  which was  classified as a
current asset held for sale at December 31, 1996. These decreases were partially
offset by  increased  cash and cash  equivalents  and the payment in 1997 of the
$1.6 million SAR liability at December 31, 1996.

         Credit Facility. On April 1, 1996, the Company amended and restated its
credit  facility  with  two  banks to  provide  a $60.0  million  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 $40.0 million  to $60.0  million  in February  1997 based on the
increase in the  Company's  estimated net proved  reserves in 1996.  Outstanding
revolving loan balances under the Company's  credit  facility,  which were $14.5
million and $33.9  million at December 31, 1997 and 1996,  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 holders of the Company's stock.

         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 $11.0  million  and $13.1  million  outstanding  as of
December 31, 1997 and 1996, respectively.  In June 1997, Panterra entered into a
credit  agreement  replacing a previous  agreement  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.

         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.

         Capital and Exploration  Expenditures.  The Company's  expenditures for
exploration and development of oil and gas properties and  acquisitions  are the
primary use of its capital  resources.  The  following  table sets forth certain
information  regarding  the costs  incurred  by the  Company  in its oil and gas
activities during the periods indicated.

         The Company's  total costs incurred in 1997 increased  $36.6 million or
70% to  $89.2  million  compared  to $52.6  million  in  1996.  Proved  property
acquisitions  increased  $6.3 million to $27.3 million in 1997 compared to $21.0
million in 1996. 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.   Several  smaller
acquisitions  were also completed  during 1997 totaling  $560,000 in addition to
follow-on  acquisitions  relating to interests  purchased  in 1996.  The Company
spent $61.9  million in 1997 for  unproved  property  acquisitions  and domestic
exploration and development compared to $31.6 million in 1996 as a result of the
Company's expanded drilling programs.

         The  Company's  total  costs  incurred in 1996  increased  63% to $52.6
million  compared  to  $32.3  million  in  1995.  Proved  property  acquisitions
increased  $12.8  million to $21.0  million in 1996  compared to $8.1 million in
1995. 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 the Siete properties in 1996 and
1997 totaling $4.6 million.  In October 1996,  the Company  acquired  additional
interests  in its Elk City Field  located  in  Oklahoma  from Sonat  Exploration
Company for $5.7  million.  Several  smaller  acquisitions  were also  completed
during 1996 totaling  $3.4 million.  The Company spent $31.6 million in 1996 for
unproved property acquisitions and domestic exploration and development compared
to  $24.3  million  in 1995  as a  result  of the  Company's  expanded  drilling
programs.

         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 anticipates  spending  approximately $94.0 million
for  capital and  exploration  expenditures  with $56.0  million  allocated  for
ongoing  domestic  exploration  and  development  in each of 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  ("BLM")
when the Project was initially  approved.  A decision from the Interior Board of

                                      -33-
<PAGE>

Land Appeals ("IBLA") 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 December 31, 1997,  $2.1 million was  outstanding
under this loan. 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.

    In February  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.

    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
January 1, 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 March 1995, the Financial Accounting Standards Board ("FASB") issued
Statement of Financial  Accounting  Standards ("SFAS") No. 121,  "Accounting for
the  Impairment of Long-Lived  Assets and for  Long-Lived  Assets to be Disposed
Of," which addresses the impairment of proved oil and gas properties. On October
1, 1995, the Company adopted the provisions of the  Statement.  The SFAS No. 121
impairment test compares the expected undiscounted future net revenues from each
producing  field  with  the  related  net  capitalized  costs at the end of each
period.  When the net  capitalized  costs  exceed  the  undiscounted  future net
revenues,  the cost of the  property is written  down to "fair  value" using the
discounted  future net revenues for the producing field. The Company recorded an
additional  impairment charge for proved  properties  related to the adoption of
SFAS No. 121 of $1.0 million in the fourth quarter of 1995.

         In November 1996,  the Company  adopted a stock option plan (the "Stock
Option Plan") which covers a maximum of 700,000  shares.  Options  granted under
the Stock Option Plan are to be exercisable at the market price of Company stock
on the  date of  grant  and have a term of ten  years  but may not be  exercised
during the initial five years.  Options vest twenty-five  percent on the date of
grant and an additional  twenty-five  percent upon the completion of each of the
following  three years of employment  with the Company.  Options however will be
fully vested in the event of an employment termination due to death,  disability
or  normal  retirement,  and  options  may  terminate  upon any  termination  of
employment  for  cause.  In the event of any  acquisition  of the  Company,  the
options  will  also  fully  vest  and  upon  completion  of  such   acquisition,
unexercised   options  will  terminate.   The  Company  adopted  SFAS  No.  123,
"Accounting for Stock-Based  Compensation," for the year ended December 31, 1996
through  compliance with the disclosure  requirements set forth in SFAS No. 123.
Effective  November 21,  1996,  the Company  authorized  the issuance of 256,598
options, of which 234,983 were outstanding at December 31, 1997,  exercisable at
$20.50 per share,  the fair market value on the date of issuance,  in connection
with the  termination of future awards under the Company's SAR plan. On December
31, 1996, the Company granted options to purchase 42,880 shares of the Company's
common stock under the Stock Option Plan,  exercisable at $24.875 per share, the
fair market value on the date of issuance.  On May 21, 1997, the Company granted
options to purchase  74,057 shares of the Company's  common stock at $29.375 per
share, the fair market value on the date of issuance,  and on December 31, 1997,
options to purchase 107,423 shares of the Company's stock were granted at $35.00
per share, the fair market value on the date of issuance.

         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 year,  and
diluted  net income per share of common  stock is  calculated  by  dividing  net
income by the weighted average of common shares and other dilutive securities.

         In  February  1997,  the FASB  issued  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 are subject to the new disclosure requirements of the
Statement.

         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.

                                      -35-
<PAGE>

         In June 1997, the FASB issued SFAS No. 131, "Disclosures about Segments
of an Enterprise and Related  Information,"  effective for financial  statements
for periods  beginning  after  December 15,  1997.  The  Statement  requires the
Company to report certain  information about operating segments in its financial
statements  and  certain  information  about  its  products  and  services,  the
geographic  areas in which it operates and its major  customers.  The Company is
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 reviewing its
future disclosure formats to facilitate financial analysis.

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.

Schedules appears in Item 14(a) of this report.

ITEM 9.  CHANGES AND DISAGREEMENTS WITH ACCOUNTANTS ON
         ACCOUNTING AND FINANCIAL DISCLOSURE

         On April 3,  1997,  the  Company  dismissed Coopers & Lybrand L.L.P. as
independent  accountants  for the  Company.  Also on April 3, 1997,  the Company
engaged Arthur Andersen LLP as independent accountants for the Company for 1997.
The  decision  to  change  independent  accountants  was  approved  by the Audit
Committee of the Company's Board of Directors.

         The  reports of Coopers & Lybrand  L.L.P.  on the  Company's  financial
statements for the past two years  contained no adverse opinion or disclaimer of
opinion and were not  qualified  or modified as to  uncertainty,  audit scope or
accounting  principles.  Further,  during the two most recent  fiscal  years and
interim period subsequent to December 31, 1996, there have been no disagreements
with  Coopers  &  Lybrand  L.L.P.  on any  matter of  accounting  principles  or
practices, financial statement disclosure, or auditing scope or procedure or any
reportable events.  The decision to change independent  accountants was based on
the  Company's  efforts to obtain  what it  believes  to be more  cost-effective
accounting and auditing services.

Board of Directors and Stockholders
St. Mary Land & Exploration Company and Subsidiaries:

We have audited the accompanying  consolidated  balance sheet of St. Mary Land &
Exploration Company (a Delaware corporation) and Subsidiaries as of December 31,
1997, and the related consolidated  statements of income,  stockholders' equity,
and cash  flows for the year then  ended.  These  financial  statements  are the
responsibility of the Company's management.  Our responsibility is to express an
opinion on these financial statements based on our audit.

We conducted our audit in accordance with generally accepted auditing standards.
Those standards  require that we plan and perform the audit to obtain reasonable
assurance   about  whether  the  financial   statements  are  free  of  material
misstatement.  An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements.  An audit also includes
assessing the  accounting  principles  used and  significant  estimates  made by
management,  as well as evaluating the overall financial statement presentation.
We believe that our audit provides a reasonable basis for our opinion.

In our opinion,  the financial  statements  referred to above present fairly, in
all material  respects,  the consolidated  financial position of St. Mary Land &
Exploration   Company  and  Subsidiaries  as  of  December  31,  1997,  and  the
consolidated  results of their operations and their cash flows for the year then
ended in conformity with generally accepted accounting principles.

two years in the period ended  December 31, 1996 in  conformity  with  generally
accepted accounting principles.

              ST. MARY LAND & EXPLORATION COMPANY AND SUBSIDIARIES
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                DECEMBER 31, 1997


1.    Summary of Significant Accounting Policies:

     Description of Operations:

         St. Mary Land & Exploration  Company (the  "Company") is an independent
energy  company  engaged  in  the  exploration,   development,  acquisition  and
production  of crude oil and  natural gas in the United  States and Canada.  The
Company's  operations  are  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. In February 1997, the Company  completed
the sale of its interest in the Russian joint venture.

     Reclassifications:

         Certain amounts in the 1996 and 1995 consolidated  financial statements
have been reclassified to correspond to the 1997 presentation.

     Basis of Presentation:

         The  consolidated  financial  statements  include  the  accounts of the
Company and its  subsidiaries,  all of which are wholly owned.  All  significant
intercompany accounts and transactions have been eliminated.

         The Company  accounts for its investment in Summo Minerals  Corporation
under the equity method of accounting.  The Company accounted for its investment
in the Russian joint venture under the equity method until February  1997,  when
the Russian  joint  venture  investment  was sold.  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's interests in other oil and
gas ventures and partnerships are  proportionately  consolidated,  including its
investment in Panterra Petroleum ("Panterra").

     Cash and Cash Equivalents:

         The Company considers all highly liquid  investments  purchased with an
initial  maturity of three months or less to be cash  equivalents.  The carrying
value  of  cash  and  cash  equivalents  approximates  fair  value  because  the
instruments have maturity dates of three months or less.

     Concentration of Credit Risk:

         Substantially  all of the Company's  receivables are within the oil and
gas  industry,  primarily  from  purchasers  of oil and gas  and  joint  venture
participants.  Although  diversified  within many companies,  collectibility  is
dependent upon the general economic conditions of the industry.  The receivables
are not collateralized and to date, the Company has had minimal bad debts.

                                      F-8
<PAGE>

         The Company has accounts  with separate  banks in Denver,  Colorado and
Shreveport, Louisiana. At December 31, 1997 and 1996, the Company had $7,295,000
and  $1,864,000,  respectively,  invested in money  market funds  consisting  of
corporate commercial paper, repurchase agreements and U.S. Treasury obligations.
The Company's policy is to invest in conservative,  highly rated instruments and
to limit the amount of credit exposure to any one institution.

     Oil and Gas Producing Activities:

         The Company follows the successful efforts method of accounting for its
oil  and  gas  properties.   Under  this  method  of  accounting,  all  property
acquisition costs and costs of exploratory and development wells are capitalized
when  incurred,  pending  determination  of  whether  the well has found  proved
reserves.  If an exploratory  well has not found proved  reserves,  the costs of
drilling  the well are charged to expense.  The costs of  development  wells are
capitalized whether productive or nonproductive.

         Geological and geophysical costs on exploratory prospects and the costs
of carrying and  retaining  unproved  properties  are  expensed as incurred.  An
impairment  allowance  is  provided  to the  extent  that  capitalized  costs of
unproved  properties,  on a  field-by-field  basis,  are  not  considered  to be
realizable.  Depletion,  depreciation and  amortization  ("DD&A") of capitalized
costs of proved oil and gas  properties  is provided on a  field-by-field  basis
using the units of production method based upon proved reserves. The computation
of DD&A takes into  consideration  restoration,  dismantlement  and  abandonment
costs  and the  anticipated  proceeds  from  equipment  salvage.  The  estimated
restoration,  dismantlement  and abandonment  costs are expected to be offset by
the estimated residual value of lease and well equipment.

         In March 1995, the Financial Accounting Standards Board ("FASB") issued
Statement of Financial  Accounting  Standards ("SFAS") No. 121,  "Accounting for
the  Impairment of Long-Lived  Assets and for  Long-Lived  Assets to be Disposed
Of,"  which  addresses  the  impairment  of proved oil and gas  properties.  The
Company  adopted SFAS No. 121 as of October 1, 1995 and  recorded an  additional
impairment  charge for proved  properties of $1,003,000 in the fourth quarter of
1995.  During 1997 and 1996 the Company recorded  impairment  charges for proved
properties of $5,202,000 and $408,000, respectively. The SFAS No. 121 impairment
test compares the expected  undiscounted future net revenues on a field-by-field
basis with the related net capitalized costs at the end of each period. When the
net capitalized costs exceed the undiscounted  future net revenues,  the cost of
the  property  is  written  down to  "fair  value,"  which is  determined  using
discounted future net revenues from the producing property.

         Prior to the  adoption of SFAS No. 121,  the net  capitalized  costs of
proved  oil and gas  properties  were  limited  to the  aggregate  undiscounted,
after-tax,  future  net  revenues  determined  on a  field-by-field  basis  (the
"ceiling test"). If the net capitalized  costs exceeded the ceiling,  the excess
was recorded as a charge to operations.  The Company recorded impairment charges
for proved  properties  under this ceiling test method of $1,673,000 in 1995 due
to price declines and downward reserve revisions.

         Gains and losses are recognized on sales of entire  interests in proved
and unproved  properties.  Sales of partial  interests are generally  treated as
recoveries of costs.

                                      F-9

     Other Property and Equipment:

         Other property and equipment is recorded at cost. Costs of renewals and
improvements  that  substantially  extend  the  useful  lives of the  assets are
capitalized.  Maintenance  and repairs are expensed when incurred.  Depreciation
and amortization is provided using the  straight-line  method over the estimated
useful lives of the assets from 3 to 15 years.  Gains and losses on dispositions
are included in operations.

     Restricted Cash:

         Proceeds from the sales of certain oil and gas producing properties are
held in escrow and restricted for future  acquisitions under a tax-free exchange
agreement.  These funds have been  invested in money market funds  consisting of
corporate commercial paper,  repurchase agreements and U.S. Treasury obligations
and are carried at cost, which approximates market.

     Gas Balancing:

         The Company uses the sales method to account for gas imbalances.  Under
this  method,  revenue  is  recorded  on the basis of gas  actually  sold by the
Company.  The Company  records revenue for its share of gas sold by other owners
that cannot be balanced in the future due to  insufficient  remaining  reserves.
The  related  receivable  totaling  $850,000  at  December  31, 1997 and 1996 is
included in other  assets in the  accompanying  balance  sheets.  The  Company's
remaining  underproduced  gas  balancing  position is included in the  Company's
proved oil and gas reserves (see Note 12).

     Financial Instruments:

         The Company periodically uses commodity contracts to hedge or otherwise
reduce  the  impact  of oil and gas  price  fluctuations.  Gains  and  losses on
commodity  hedge  contracts are recognized as an adjustment to revenues when the
related oil or gas is sold.  Cash flows from such  transactions  are included in
oil  and  gas  operations.  The  Company  realized  net  losses  of  $3,242,000,
$4,253,000 and $11,000 on these contracts for the years ended December 31, 1997,
1996 and 1995 respectively.

         In  connection  with these  hedging  transactions,  the  Company may be
exposed  to  nonperformance  by  other  parties  to  such  agreements,   thereby
subjecting the Company to current oil and gas prices.  However, the Company only
enters into hedging  contracts with large  financial  institutions  and does not
anticipate nonperformance.

     Income Taxes:

         Deferred  income taxes are provided on the  difference  between the tax
basis  of an  asset  or  liability  and its  carrying  amount  in the  financial
statements.  This  difference  will result in taxable  income or  deductions  in
future years when the reported  amount of the asset or liability is recovered or
settled, respectively.

     Net Income 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


                                      F-10
<PAGE>

by the  weighted  average of common  shares  outstanding  during each year,  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 years ended  December 31, 1997,  1996 and 1995 were 132,666,
66,326, and 40,893, respectively.  All net income of the Company is available to
common  stockholders.  The  adoption  of SFAS No. 128 had no effect on basic net
income per share  compared to primary  net income per share as reported  for the
years ended  December 31, 1996 and 1995.  Restated  diluted net income per share
for the year ended  December  31, 1996 was $1.17  compared to fully  diluted net
income per share of $1.18 as reported. There was no effect on diluted net income
per share  compared to fully  diluted  net income per share as reported  for the
year ended December 31, 1995.

     Use of Estimates in the Preparation of Financial Statements:

         The  preparation of financial  statements in conformity  with generally
accepted  accounting  principles  requires  management  to  make  estimates  and
assumptions  that  affect the  reported  amounts of assets and  liabilities  and
disclosure of  contingent  assets and  liabilities  at the date of the financial
statements  and the  reported  amounts  of  revenues  and  expenses  during  the
reporting period. Actual results could differ from those estimates.

     Impact of Recently Issued Accounting Standards:

         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 are subject to the new disclosure requirements of the
Statement.

         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 June 1997, the FASB issued SFAS No. 131, "Disclosures about Segments
of an Enterprise and Related  Information,"  effective for financial  statements
for periods  beginning  after  December 15,  1997.  The  Statement  requires the
Company to report certain  information about operating segments in its financial
statements  and  certain  information  about  its  products  and  services,  the
geographic  areas in which it operates and its major  customers.  The Company is
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 reviewing its
future disclosure formats to facilitate financial analysis.

3.    Summo Minerals Corporation Investment and Receivable:

         As of December 31, 1997 and 1996,  the Company owned  9,924,093 (37% of
total shares outstanding) and 9,644,093 (49% of total shares outstanding) shares
of Summo Minerals Corporation ("Summo"), a North American mining company, with a
total cost of $5,859,000 and  $5,608,000,  respectively.  The Company also owned
warrants to acquire an additional  616,090 and 6,261,000  shares of Summo common
stock as of December 31, 1997 and 1996, respectively. The exercise price for the
warrants is $.77,  using the  Canadian  exchange  rate in effect on December 31,
1997 ($.70).  Summo completed its initial public offering  effective October 31,
1994 at $.44 per share.  The market value of this  investment  was $1,806,000 at
December  31, 1997 and  $8,444,000  at December  31,  1996.  For the years ended
December 31, 1997 and 1996, the Company  reported equity in losses from Summo of
$526,000 and $457,000, respectively.

         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
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
("BLM") when the Project was  initially  approved.  A decision from the Interior
Board of Land Appeals  ("IBLA") is expected in the second  quarter of 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.  As of  December  31,
1997,  $2,081,000 was outstanding under this loan.  Additional  amounts totaling
$235,000 have been advanced to Summo under this loan through the end of February
1998.  Interest accrues on the amounts outstanding at the prime rate plus 1%. 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
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.

         At  December  31,  1997,  the  Company  had  state net  operating  loss
carryforwards  of approximately  $32,200,000  which expire between 1998 and 2012
and  alternative  minimum  tax credit  carryforwards  of  $784,000  which may be
carried forward indefinitely.  The Company's valuation allowance relates in part
to its state net operating  loss  carryforwards,  since the Company  anticipates
that a portion of the carryovers from prior years will expire before they can be
utilized, and in part to a portion of the anticipated state benefit from federal
income  tax  expense  incurred  as  the  Company's  existing  taxable  temporary
differences  reverse. The net change in valuation allowance in 1997 results from
the current year  calculation  of deferred state income tax for Oklahoma and the
state  benefit of federal  income  tax which is not  offset by  reversing  state
temporary differences.

         Federal income tax expense (benefit) differs from the amount that would
be provided by applying the  statutory  U.S.  Federal  income tax rate to income
before income taxes for the following reasons:

5.    Long-term Debt and Notes Payable:

         In April 1996, the Company amended and restated its long-term revolving
credit  facility dated March 1, 1993 and extended its maturity to June 30, 1999.
Borrowings  under this agreement are limited to the lesser of $60,000,000 or the
current  borrowing base, as determined by the bank annually.  The borrowing base
at  December  31, 1996 was  $40,000,000  and was  increased  to  $60,000,000  in
February 1997 based on year-end  reserve values.  The agreement has a three-year
term, at the end of which borrowings can be converted to a five-year  amortizing
loan.  The Company can elect to allocate up to 50% of available  borrowings to a
short  term  tranche  due in 364  days.  Borrowings  under  this  agreement  are
collateralized by a mortgage of substantially all of the Company's producing oil
and gas  properties.  In addition,  the Company  must comply with certain  other
covenants,  including  maintenance of stockholders' equity at a specified level,
limitations on additional  indebtedness and payment of dividends. As of December
31, 1997 and 1996,  $14,450,000 and $33,875,000,  respectively,  was outstanding
under this credit facility.

                                      F-14
<PAGE>

         Through  March 31,  1995,  interest on  borrowings  was computed at the
bank's  prime rate or LIBOR  plus 1.5%.  Effective  April 1, 1995,  interest  on
borrowings,  based on debt to capitalization  ratios, and commitment fees on the
unused portion of borrowings are calculated as follows:

INTEREST RATES:

    Debt to Capitalization Ratio        Revolving Loan       Term Loan
    ----------------------------        --------------       ---------
    Less than 30%                       Prime rate or        Prime rate or

COMMITMENT FEES ON UNUSED PORTION:

    Unused Portion of Borrowings        Short Term Tranche   Long Term Tranche

    Less than 50% of
         available borrowings                 .125%                .25%
    Greater than 50% of
         available borrowings                 .375%                .50%

         At December 31, 1997 and 1996,  the  Company's  debt to  capitalization
ratio as defined  was 13.3% and  37.5%,  respectively.  At  December  31,  1997,
interest on borrowings  was computed at the bank's prime rate or LIBOR plus .50%
(8.5% or 6.31%, respectively).  At December 31, 1996, interest on borrowings was
computed  at the  bank's  prime  rate  or  LIBOR  plus  .75%  (8.25%  or  6.31%,
respectively).

         In June 1997,  Panterra  entered  into a credit  agreement  with a bank
replacing  a  previous  credit  agreement  due March 31,  1999.  The new  credit
agreement  as  modified on June 17, 1997  includes a two-year  revolving  period
converting to a five year  amortizing  loan on June 30, 1999.  Borrowings  under
this agreement are limited to the lesser of $40,000,000 or the current borrowing
base, as determined by the bank semiannually. The borrowing base at December 31,
1996 was $26,000,000 and was increased to $27,000,000 effective January 1, 1998.
During the revolving period, interest on borrowings,  based on debt to partners'
capital ratios,  and commitment fees on the unused portion of the borrowings are
calculated as follows:

Debt to Partners' Capital Ratio    Interest Rates                Commitment Fees
- -------------------------------    --------------                ---------------
Less than or equal to 30%          Prime rate or LIBOR + .75%         .25%
Greater than 30%, less than or
       equal to 100%               Prime rate or LIBOR + 1.0%         .25%
Greater than 100%                  Prime rate or LIBOR + 1.25%        .25%

         At December 31, 1997,  Panterra's  debt to partners'  capital  ratio as
defined was 53% and interest on  borrowings is computed at the bank's prime rate
or LIBOR plus 1.00% (8.5% or 6.81%,  respectively).  Interest on  borrowings  at
December  31,  1996 was  payable  at the  bank's  prime rate or LIBOR plus 1.25%
(8.25% or 7.05%,  respectively).  Principal payments during the revolving period
are not  required if the loan amount is less than the  current  borrowing  base.
During the amortization period,  monthly principal payments are payable at rates
decreasing  from 2.0% to 1.4% of the  outstanding  balance  through June 2004 at
which time the remaining principal balance is due.

         The  new  Panterra  credit  agreement  is   collateralized  by  all  of
Panterra's  oil and gas  properties and contains  covenants  which,  among other
things, restrict the acquisition of assets and the incurrence of additional debt
and require that certain minimum financial ratios be maintained.  As of December
31, 1997 and 1996, $11,000,000 and $13,100,000,  respectively,  were outstanding
under this credit facility.  The Company owns a 74% general partnership interest
in Panterra.

         The carrying  value of long-term debt  approximates  fair value because
the debt is variable rate and reprices in the short term.

         The Company's liability for estimated annual principal payments for the
next five years under both notes payable are as follows:

6.   Commitments and Contingencies:

         The Company  leases  office space under various  operating  leases with
terms  extending  as far as June 30, 2003.  The annual  minimum  lease  payments
approximate  $550,000.  The  Company has  noncancelable  annual  subleases  with
affiliates of approximately  $75,000 for the same term as the Company's  primary
office lease. Rent expense, net of sublease income, was $447,000,  $426,000, and
$131,000 in 1997, 1996, and 1995, respectively.

         The  Company  has the  following  commodity  contracts  in  place as of
December 31, 1997, to hedge or otherwise  reduce the impact of oil and gas price
fluctuations:

    Product          Volumes/month         Fixed Price           Duration

         The fair value of the Company's  commodity  hedging  contracts based on
year-end futures pricing would have caused the Company to receive  approximately
$150,000 if these contracts had been terminated on December 31, 1997.

         At  December  31,  1997,  Panterra,  in which  the  Company  owns a 74%
interest,   held  various  hedge  contracts   covering  70,000  Bbls  of  future
production.  These  contracts  expire at various dates through March 1998,  with
price floors  ranging  from $19.00 per Bbl to $20.00 per Bbl and price  ceilings
ranging from $23.00 per Bbl to $24.00 per Bbl. If the open hedging contracts had
been  liquidated at December 31, 1997,  Panterra would have recognized a gain of
approximately $121,000.

         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 14% of
its estimated  1998 gas  production at an average fixed price of $2.11 per MMBtu
and  approximately  4% of its estimated  1998 oil production at an average fixed
price of $18.18 per Bbl.  The Company has also  purchased  options  resulting in
price collars on approximately 7% of the Company's estimated 1998 gas production
with price  ceilings  between $2.55 and $3.00 per MMBtu and price floors between
$1.95 and  $2.00 per MMBtu as well as  options  resulting  in price  collars  on
approximately  5% of the  Company's  estimated  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.

7.    Compensation Plans:

         In January 1992,  the Company  adopted two  compensation  plans for key
employees.  A cash bonus plan not to exceed 50% of the  participants'  aggregate
base  salaries  was  adopted,  and any  awards are based on  performance.  A net
profits interest bonus plan allows  participants to receive an aggregate 10% net
profits  interest  after the Company has  recovered  100% of its  investment  in
various pools of oil and gas wells  completed or acquired  during the year. This
interest is increased to 20% after the Company  recovers 200% of its investment.
The Company records compensation expense once it recovers its investment and net
profits attributable to the properties are payable to the employees. The Company
recorded  compensation expense of $320,000 in 1997 and $119,000 in 1996 relating
to net profits attributable to these properties.

         In March 1992, the Company adopted a stock appreciation  rights ("SAR")
plan for officers and directors and awarded  90,962 share rights with a value of
$4.26 per share effective  January 1, 1992.  SARs vest over a four-year  period,
with payment occurring five years after the date of grant. The SAR plan replaced
the  restricted  stock bonus plan.  Between 1993 and 1996 the Company  awarded a
total of 171,412  share  rights  with values  ranging  from $11.50 to $14.00 per
share.  Compensation  expense  recognized  under  the  SAR  plan  was  $161,000,
$1,567,000, and $220,000 in 1997, 1996 and 1995, respectively. In November 1996,
the Company terminated future awards under the Company's SAR plan and capped the
value of the share  rights  under the SAR plan at the then fair market  value of
the  Company's  common  stock of $20.50 per share.  The  resulting  liability is
classified as current and long-term in the consolidated balance sheets, based on
expected payment dates. SAR compensation  expense recorded after the termination
of future awards  relates to the vesting of SARs  outstanding at the time of the
termination of future awards.

         Through  September 1992, the Company had a restricted  stock bonus plan
("Plan") covering officers and key employees. The Plan provided for the granting
of stock and cash not to exceed 100% of the  participant's  then annual  salary.
The Plan provided that any portion or all of the stock could be purchased by the
Company in the case of termination  of employment for any reason.  A participant
has the option at any time to sell shares acquired under the Plan to the Company
at a price  related to their  fair  market  values as  defined  in the Plan.  At
December 31, 1997,  there were 33,520  shares issued and  outstanding  under the
Plan. The Company's stock price was $35.00 at December 31, 1997.

         The Company has a defined  contribution  pension plan  ("401(k)  Plan")
qualified under the Employee Retirement Income Security Act of 1974. This 401(k)
Plan allows  eligible  employees to contribute up to 9% of their base  salaries.
The Company  matches each  employee's  contributions  up to 6% of the employee's
base salary and also may make additional  contributions  at its discretion.  The
Company's  contributions to the 401(k) Plan amounted to $231,000,  $199,000, and
$183,000 for the years ended December 31, 1997, 1996 and 1995, respectively.

         During 1996 the  Company  established  the St. Mary Land &  Exploration
Company Stock Option Plan and the St. Mary Land & Exploration  Company Incentive
Stock Option Plan (collectively, the "Stock Option Plan"). The Stock Option Plan
grants  options to purchase  shares of the  Company's  common  stock to eligible
employees,  contractors,  and  current  and  former  members  of  the  Board  of
Directors.  The Company has reserved  700,000 shares of its own common stock for
issuance  under the Stock Option Plan.  During 1996 options to purchase  256,598
shares,  in connection with the termination of future awards under the Company's
SAR plan, and 42,880 shares of the Company's common stock were granted under the
Stock Option Plan at exercise prices of $20.50 and $24.875, respectively,  which
were equal to the respective  market prices of the stock on the grant dates. The
vesting  periods of these  options  vary from 0 to 3 years,  and the options are
exercisable  for the period from five to ten years  after the date of grant.  No
options  under the  Stock  Option  Plan were  exercised  during  the year  ended
December  31, 1996.  In 1997,  14,072  options  under the Stock Option Plan were
exercised at $20.50 per share, and an additional 74,057 and 107,423 options were
granted at $29.375 and $35.00 per share, respectively.

         Also, in 1990 and 1991, the Company granted certain officers options to
acquire  54,614 shares of common stock at an exercise  price of $3.30 per share.
The options are now fully vested and expire ten years from the respective  dates
of grant. In 1997, 34,614 of these options were exercised.

         In  October  1995,  the FASB  issued  SFAS  No.  123,  "Accounting  for
Stock-Based  Compensation."  This  Statement  establishes a fair value method of
accounting for  stock-based  compensation  plans either  through  recognition or
disclosure.  The Company has elected to continue following Accounting Principles
Board Opinion No. 25,  "Accounting  for Stock Issued to Employees"  (APB No. 25)
and has elected to adopt SFAS No. 123  through  compliance  with the  disclosure
requirements  set forth in the  Statement.  Because  the  exercise  price of the
Company's employee stock options equals the market price of the underlying stock
on the date of grant,  no compensation  expense is recognized  under APB No. 25.
Pro forma information regarding net income and earnings per share is required by
SFAS No. 123 and has been  determined  as if the Company had  accounted  for its
employee stock options under the fair value method of that Statement.

         The fair value of options is  measured  at the date of grant  using the
Black-Scholes  option-pricing  model.  The fair value of options granted in 1997
was  estimated  using  the  following  weighted-average  assumptions:  risk-free
interest rate of 5.7%; dividend yield of .49%; volatility factor of the expected
market  price of the  Company's  common  stock of 37.29%;  and  weighted-average
expected life of the options of 7.1 years. The fair value of the options granted
in  1996  was  estimated  using  the  following  weighted-average   assumptions:
risk-free  interest rate of 6.2%;  dividend yield of .76%;  volatility factor of
the  expected  market  price  of the  Company's  common  stock  of  37.88%;  and
weighted-average  expected  life of the  options of 4.8 years.  No stock  option
grants were made in 1995.

         The  Black-Scholes  option  valuation  model was  developed  for use in
estimating  the fair value of traded  options that have no vesting  restrictions
and are fully  transferable.  In addition,  option  valuation models require the
input of highly  subjective  assumptions  including  the  expected  stock  price
volatility.  Because the Company's  employee stock options have  characteristics
significantly different from those of traded options, and because changes in the
subjective input assumptions can materially  affect the fair value estimate,  it
is management's  opinion that the existing  models do not necessarily  provide a
reliable single measure of the fair value of its employee stock options.

         For purposes of pro forma disclosures,  the estimated fair value of the
options  is  amortized  to  expense  over  the  options'  vesting  period.   Had
compensation  cost been  determined  based on the fair value at grant  dates for
stock option awards  consistent  with SFAS No. 123, the Company's net income and
earnings  per share would have been reduced to the pro forma  amounts  indicated
below:

         The effects of applying  SFAS No. 123 in the pro forma  disclosure  are
not necessarily  indicative of actual future amounts,  and SFAS No. 123 does not
apply to awards  granted  prior to 1995.  Additional  awards in future years are
anticipated.

         On September 18, 1997 the Board of Directors approved the St. Mary Land
& Exploration  Company Employee Stock Purchase Plan (Stock Purchase Plan), which
became  effective  January  1,  1998.  Under the Stock  Purchase  Plan  eligible
employees  may purchase  shares of the Company's  common stock  through  payroll
deductions  of up to 15% of eligible  compensation.  The  purchase  price of the
stock is the lower of 85% of the fair market  value of the stock on the first or
last day of the purchase period. The Company has set aside 500,000 shares of its
common stock to be available for issuance  under the Stock  Purchase  Plan.  The
Stock Purchase Plan must be approved by the Company's shareholders at the annual
meeting of stockholders in May 1998.

8.    Pension Plans:

         The Company's employees  participate in a noncontributory  pension plan
covering  substantially all employees who meet age and service requirements (the
"Primary Plan").  Benefits  provided under this pension plan are based primarily
on each employee's  career  earnings.  As of December 31, 1997, plan assets were
invested primarily in diversified stock and bond funds.

         In addition,  the Company has a  supplemental  noncontributory  pension
plan covering certain management employees (the "Supplemental  Plan").  Benefits
are  based  mainly  on  each  participant's  years  of  service,  final  average
compensation and estimated benefits received from certain other plans.

9.    Related Party Transactions:

         Through  October  1994,  the  majority  of the  Company's  oil  and gas
operations, other than Louisiana royalties but including acquisition of unproved
properties, was administered by SMOC. Operations were conducted under a domestic
agreement with SMOC and various  individuals  (the  "Anderman  Group") which was
effective  January 1, 1992,  amended July 1, 1993 and terminated on December 31,
1995.  Through the termination  date the Company paid 70% of all costs for lease
acquisitions,  geophysical surveys, drilling and production and owned 68% of all
resulting  properties,  production and reserves.  Through December 31, 1995, the
Company also paid 65% of all overhead costs of SMOC incurred for exploration and
production activities, and through September 1995, quarterly fees of $125,000 to
the Anderman Group.

         Effective  April 1, 1995,  the  Company  gave  notice that it would not
participate in any new international ventures managed by the Anderman Group, and
on November 30, 1995,  withdrew  from all  international  partnerships  with the
exception of those with interests in Russia and Canada. During 1995, the Company
recorded a charge to operations of $252,000  resulting from its withdrawal  from
the international partnerships.

         Billings  from  SMOC,  which  represent  charges  for lease  operating,
exploration,  development and general and  administrative  expenses  amounted to
$11,451,000 for the year ended December 31, 1995.

10.    Investment in Russian Joint Venture:

         In September  1991,  the Company,  through an affiliate of the Anderman
Group,  acquired a 22% interest in The Limited Liability Company  Chernogorskoye
(the  "Russian  joint  venture").  The  Company's  interest in the Russian joint
venture was reduced to 18% in 1993.  The Russian joint venture is developing the
Chernogorskoye  field in western  Siberia.  On December  16,  1996,  the Company
executed an  Acquisition  Agreement  to sell its  interest in the Russian  joint
venture to Khanty  Mansiysk Oil  Corporation  ("KMOC"),  formerly Ural Petroleum
Corporation.  Closing of the  transaction  occurred on February  12,  1997.  The
Company's  equity in income for the Russian  joint  venture for 1997 through the
date of sale was  $201,000.  In  accordance  with the  terms of the  Acquisition
Agreement, the Company received cash consideration of approximately $5.6 million
before transaction costs,  approximately $1.9 million of KMOC common stock 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.  As of December 31, 1996 the
Company's  investment  in  the  Russian  joint  venture  was  classified  in the
financial statements as held for sale.

11.    Real Estate Assets:

         In a prior year the Company  made the  decision  to sell its  remaining
real estate projects.  Accordingly,  the Company's real estate  activities since
that time have been  presented as  discontinued  operations in the statements of
income. The Company's remaining real estate assets consist of land held for sale
with a carrying  cost of $1,149,000  and  $1,386,000 as of December 31, 1997 and
1996, respectively, which is less than the estimated net realizable values.

12.    Disclosures About Oil and Gas Producing Activities:

    Major Customers:

         During 1997 two customers  individually  account for 10.6% and 10.2% of
the  Company's  total  oil and gas  production  revenue.  Sales  to one of these
customers constituted 17.3% of total 1996 oil and gas production revenue.  There
were no sales to individual customers  constituting 10% or more of total oil and
gas production revenue during 1995.

    Oil and Gas Reserve Quantities (Unaudited):

         The reserve  information as of December 31, 1997,  1996,  1995 and 1994
was prepared by the Company and Ryder Scott Company. The Company emphasizes that
reserve estimates are inherently imprecise and that estimates of new discoveries
are more  imprecise  than  those of  proved  producing  oil and gas  properties.
Accordingly,  these  estimates  are  expected  to change  as future  information
becomes available.

         Proved oil and gas reserves are the estimated  quantities of crude oil,
natural gas and  natural  gas liquids  which  geological  and  engineering  data
demonstrate  with  reasonable  certainty to be  recoverable in future years from
known  reservoirs  under  existing  economic and  operating  conditions.  Proved
developed  oil and gas  reserves  are those  expected  to be  recovered  through
existing wells with existing equipment and operating methods.

    Standardized Measure of Discounted Future Net Cash Flows (Unaudited):

         SFAS No. 69 prescribes  guidelines for computing a standardized measure
of future  net cash flows and  changes  therein  relating  to  estimated  proved
reserves.  The Company has followed these guidelines which are briefly discussed
below.

         Future cash inflows and future  production  and  development  costs are
determined by applying year-end prices and costs to the estimated  quantities of
oil and gas to be produced.  Estimated  future  income taxes are computed  using
current statutory income tax rates, including consideration for estimated future
statutory depletion and alternative fuels tax credits.  The resulting future net
cash  flows are  reduced  to  present  value  amounts  by  applying a 10% annual
discount factor.

         The  assumptions  used to compute  the  standardized  measure are those
prescribed  by the  Financial  Accounting  Standards  Board and, as such, do not
necessarily reflect the Company's  expectations of actual revenues to be derived
from those reserves,  nor their present worth.  The limitations  inherent in the
reserve  quantity  estimation  process,  as  discussed  previously,  are equally
applicable to the standardized  measure  computations  since these estimates are
the basis for the valuation process.

                                 ADMINISTRATION

     Administration.  The Board shall be responsible for  administering the Plan
and appointing the Plan Administrator.

          (a) The Board is  authorized  to  interpret  the Plan;  to  prescribe,
     amend,  and rescind rules and regulations  relating to the Plan; to provide
     for conditions and assurances  deemed necessary or advisable to protect the
     interests of the Company  with  respect to the Plan;  and to make all other
     determinations  necessary or advisable for the  administration of the Plan.
     Determinations,  interpretations,  or  other  actions  made or taken by the
     Board with respect to the Plan and Options  granted under the Plan shall be
     final and binding and conclusive for all purposes and upon all persons.

          (b) At the discretion of the Board the Plan may be  administered  by a
     Committee of two or more non-employee Directors appointed by the Board (the
     "Committee"). The Committee shall have full power and authority, subject to
     the  limitations of the Plan and any  limitations  imposed by the Board, to
     construe,  interpret  and  administer  the Plan and to make  determinations
     which shall be final,  conclusive  and binding upon all persons,  including
     any persons  having any interests in any Options which may be granted under
     the Plan, or Stock purchased under the Plan.

          (c) Where a Committee  has been created by the Board  pursuant to this
     Article  IV,  references  in the Plan to  actions  to be taken by the Board
     shall be deemed to refer to the Committee as well,  except where limited by
     the Plan or by the Board.

under the Plan,  subject to  adjustment  upon changes in  capitalization  of the
Company as provided in Section 5.2 shall be 500,000 shares.  If the total number
of shares of Stock for which Options are  exercised on any Offering  Termination
Date in accordance  with Article V exceeds the maximum number of shares of Stock
remaining  in the Plan,  the  Company  shall make a pro rata  allocation  of the
shares  available for delivery and distribution in as nearly a uniform manner as

of payroll deductions credited to the Account of each Participant under the Plan
shall be returned to him as promptly as possible.

appropriately adjusted by the Board, whose determination shall be conclusive. In
any such case,  the  number and kind of shares of Stock that are  subject to any
Option and the Option price per share shall be proportionately and appropriately
adjusted  without any change in the  aggregate  Option price to be paid therefor
upon exercise of the Option.

                                    OFFERINGS

     6.1  Semi-Annual  Offerings.  The Plan will be  implemented  by semi-annual
offerings of the Company's Stock (the  "Offerings")  commencing on January 1 and
July 1 of such year and  terminating  on June 30 and  December  31 of such year,
respectively.  The first Offering shall commence on January 1, 1998 and,  unless
all shares of Stock in the Plan shall have been  purchased  prior  thereto,  the
last Offering shall commence on July 1, 2017.

     As used in the Plan,  "Offering  Commencement  Date" means the January 1 or
July 1, as the  case  may be,  on  which  the  particular  Offering  begins  and
"Offering  Termination  Date" means the June 30 or December  31, as the case may
be, on which the particular Offering terminates.

                                   ARTICLE VII
                               PAYROLL DEDUCTIONS

     7.1 Amount of Deduction.  At the time a Participant files his authorization
for payroll deduction,  deductions shall be made from his Base Pay in accordance
with such  authorization  on each payday  which  falls on or after the  Offering
Commencement Date and on or before the Offering Termination Date during the time
he is a Participant at the rate of not less than 1% and not more than 15% of his
Base Pay during the Offering.  In the case of a part-time hourly Employee,  such
Employee's  Base Pay during an Offering shall be determined by multiplying  such
Employee's  hourly  rate of Base  Pay  during  the  Offering  by the  number  of
regularly scheduled hours of work for such Employee during such Offering.

     7.2 Participant's  Account.  All payroll  deductions made for a Participant
shall be credited to his Account under the Plan. A Participant  may not make any
separate cash payment into such Account.

     7.3  Changes in Payroll  Deductions.  A  Participant  may  discontinue  his
participation  in the Plan as  provided  in  Article X or on one  occasion  only
during the Offering  period may elect to decrease the  percentage of Base Pay of
his  contributions  to his Account by filing with the Plan  Administrator  a new
payroll  deduction  authorization,  but no other  change  can be made  during an
Offering.

     7.4 Leave of Absence.  If a  Participant  goes on a leave of absence,  such
Participant shall have the right to elect either: (a) to withdraw the balance in
his or her Account pursuant to Section 9.2 or (b) to remain a Participant in the
Plan  authorizing  deductions  to be made from  payments  by the  Company to the
Participant during such leave of absence, if any.

                                  ARTICLE VIII
                               GRANTING OF OPTION

     8.1 Number of Option Shares. On the Commencement  Date of each Offering,  a
Participant shall be deemed to have been granted an Option to purchase shares of
the Stock of the Company equal to (i) that percentage of the Employee's Base Pay
which he has elected to have  withheld (but not in any case less than 1% or more
than 15%)  multiplied by (ii) the  Employee's  Base Pay during the period of the
Offering  (iii) divided by the lesser of 85% of the market value of Stock on the
applicable  Offering  Commencement Date or 85% of the market value of each share
of Stock on the applicable  Offering  Termination  Date. The market value of the
Stock shall be determined  as provided in paragraphs  (a) and (b) of Section 8.2
below. An Employee's  Base Pay during the six-month  period of an Offering shall
be determined by multiplying his normal weekly Base Pay rate (as adjusted during
the Offering  period) by 26 or the hourly rate by 1,040;  provided  that, in the
case of a part-time hourly  Employee,  the Employee's Base Pay during the period
of an Offering shall be determined by multiplying  such  Employee's  hourly Base
Pay rate by the number of regularly  scheduled  hours of work for such  Employee
during such Offering.

     8.2 Option Price.  The option price of each share of Stock  purchased  with
payroll  deductions made during such annual  Offering for a Participant  therein
shall be the lower of:

          (a) 85% of the closing price of the Stock on the Offering Commencement
     Date or the nearest  prior  business day on which  trading  occurred on the
     NASDAQ National Market System; or

          (b) 85% of the closing price of the Stock on the Offering  Termination
     Date or the nearest  prior  business day on which  trading  occurred on the
     NASDAQ National Market System.  If the Stock of the Company is not admitted
     to trading on any of the aforesaid  dates for which  closing  prices of the
     Stock are to be determined, then reference shall be made to the fair market
     value of the Stock on that date,  as  determined  on such basis as shall be
     established or specified for the purpose by the Board.

                                   ARTICLE IX
                               EXERCISE OF OPTION

     9.1 Automatic  Exercise.  A Participant's  Option for the purchase of Stock
with payroll  deductions  made during any  Offering  will be deemed to have been
exercised  automatically  on the Offering  Termination  Date  applicable to such
Offering  for the  purchase  of the  number of full  shares  of Stock  which the
accumulated  payroll deductions in his Account at that time will purchase at the
applicable  option price (but not in excess of the number of shares of Stock for
which Options have been granted to the Participant pursuant to Section 8.1).

     9.2 Withdrawal of Account. By written notice to the Plan Administrator,  at
any time prior to the Offering  Termination  Date applicable to any Offering,  a
Participant may elect to withdraw all the accumulated  payroll deductions in his
Account at such time.

     9.3 Fractional Shares.  Fractional shares will not be issued under the Plan
and any accumulated  payroll  deductions  which would have been used to purchase
fractional  shares will be returned to any  Participant  promptly  following the
Offering Termination Date, without interest,  unless the Participant has elected
to  participate in the next following  Offering,  in which case such  deductions
shall be retained in the  Participant's  Account and applied to the  purchase of
shares of Stock in such Offering.

     9.4  Transferability of Option.  During a Participant's  lifetime,  Options
held by such Participant shall be exercisable only by that Participant.

                                      -5A-

     9.5  Delivery  of Stock.  As  promptly as  practicable  after the  Offering
Termination Date of each Offering, the Company will deliver to each Participant,
as appropriate, the Stock purchased upon exercise of his Option.

                                    ARTICLE X
                                   WITHDRAWAL

     10.1 In General.  As indicated in Section 9.2, a  Participant  may withdraw
payroll deductions  credited to his Account under the Plan at any time by giving
written  notice  to  the  Plan   Administrator  of  the  Company.   All  of  the
Participant's  payroll  deductions  credited to his Account  will be paid to him
promptly  after  receipt of his  notice of  withdrawal,  and no further  payroll
deductions  will be made from his pay during such Offering.  The Company may, at
its option,  treat any  attempt to borrow by an Employee on the  security of his
accumulated  payroll  deductions as an election,  under Section 9.2, to withdraw
such deductions.

     10.2 Effect on Subsequent  Participation.  A Participant's  withdrawal from
any Offering will not have any effect upon his eligibility to participate in any
succeeding Offering or in any similar plan which may hereafter be adopted by the
Company.

     10.3  Termination of  Employment.  Upon  termination  of the  Participant's
employment for any reason,  including  retirement  (but excluding death while in
the employ of the Company) prior to the Offering  Termination  Date, the payroll
deductions credited to his Account will be returned to him or in the case of his
death to the person or persons entitled thereto under Section 19.1.

     10.4  Termination  of  Employment  Due to Death.  Upon  termination  of the
Participant's  employment  because of his death,  his  beneficiary as defined in
Section 19.1, or if none is designated, his estate shall have the right to elect
by written  notice given to the Plan  Administrator  of the Company prior to the
earlier of the Offering  Termination  Date or the  expiration  of a period of 60
days commencing with the date of the death of the Participant either:

          (a)  to  withdraw  all  of  the  payroll  deductions  credited  to the
     Participant's Account under the Plan, or

          (b) to exercise the Participant's  Option for the purchase of Stock on
     the Offering  Termination Date next following the date of the Participant's
     death for the  purchase  of the  number of full  shares of Stock  which the
     accumulated payroll deductions in the Participant's  Account at the date of
     the  Participant's  death will purchase at the applicable option price, and
     any excess in such  Account will be returned to said  beneficiary,  without
     interest.

     In the event that no such written notice of election shall be duly received
by the office of the Plan  Administrator of the Company,  the beneficiary  shall
automatically be deemed to have elected,  pursuant to paragraph (b), to exercise
the Participant's Option.

     10.5 Leave of Absence. A Participant on leave of absence shall,  subject to
the election made by such Participant  pursuant to Section 7.4, continue to be a
Participant in the Plan so long as such Participant remains an Employee.

     11.1 Payment of Interest.  No interest will be paid or allowed on any money
paid into the Plan or  credited  to the  Account of any  Participant,  including
money which is  distributed  to an Employee or his  beneficiary  pursuant to any
provision of this Plan.

                                   ARTICLE XII
                             NO RIGHT TO EMPLOYMENT

     Nothing in the Plan shall  interfere  with or limit in any way the right of
the Company or a Subsidiary  Corporation to terminate any Employee's  employment
at any time, nor confer upon any Employee any right to continue in the employ of
the Company or a Subsidiary Corporation.

                                  ARTICLE XIII
                          AMENDMENT, MODIFICATION, AND
                             TERMINATION OF THE PLAN

     The  Board  may at any time  terminate  and from  time to time may amend or
modify the Plan. Any amendment or  modification  of the Plan by the Board may be
accomplished without approval of the shareholders of the Company,  except in the
event that shareholder approval of such amendment or modification is required by
any law or regulation governing the Company.

     No amendment,  modification, or termination of the Plan shall in any manner
adversely  affect any  outstanding  Option under the Plan without the consent of
the Participant holding the Option.

                                   ARTICLE XIV
                       ACQUISITION, MERGER OR LIQUIDATION

     14.1 Acquisition.

          (a) In the  event  that an  acquisition  occurs  with  respect  to the
     Company,  the Company may, but shall not be required to, cancel an Offering
     and all Options  outstanding as of the effective date of such  acquisition,
     whether  or not such  Options  are then  exercisable.  In that  event,  the
     payroll  deductions  credited to the Account of each  Participant  shall be
     returned to him. If the Company does not elect to cancel the Offering, such
     Offering shall terminate on the day immediately prior to the effective date
     of  the  Acquisition  and  such  date  shall  be  considered  the  Offering
     Termination Date for the Offering.

          (b) For  purposes of this  section,  an  "acquisition"  shall mean any
     transaction in which substantially all of the Company's assets are acquired
     or in which a controlling  amount of the Company's  outstanding  shares are
     acquired,  in each case by a single person or entity or an affiliated group
     of persons and entities. For purposes of this section, a controlling amount
     shall mean more than fifty percent of the issued and outstanding  shares of
     Stock of the Company.  The Company shall have the above option to cancel an
     Offering and all Options  regardless of how the acquisition is effectuated,
     whether  by  direct  purchase,   through  a  merger  or  similar  corporate
     transaction, or otherwise.

          (c) Where the Company  does not exercise its option under this Section
     14.1 the  remaining  provisions  of this  Article XIV shall  apply,  to the
     extent applicable.

                                      -7A-

     14.2  Merger  or  Consolidation.  If the  Company  shall  be the  surviving
corporation  in any merger or  consolidation,  any Offering shall pertain to and
apply to the  securities  to which a holder  of the  number  of  shares of Stock
subject to the Option would have been entitled in such merger or  consolidation,
provided that the Company shall not be considered the surviving  corporation for
purposes hereof if the Company is the survivor of a reverse triangular merger.

     14.3 Other Transactions. A dissolution or a liquidation of the Company or a
merger and  consolidation in which the Company is not the surviving  corporation
(the Company shall not be  considered  the  surviving  corporation  for purposes
hereof if the Company is the  survivor  of a reverse  triangular  merger)  shall
cause every Offering outstanding hereunder to terminate as of the effective date
of such dissolution,  liquidation,  merger or consolidation.  In that event, the
payroll deductions credited to the Account of each Participant shall be returned
to him.

                                   ARTICLE XV
                             SECURITIES REGISTRATION

     15.1 Securities  Registration.  In the event that the Company shall deem it
necessary or desirable to register under the Securities Act of 1933, as amended,
or any other applicable statute,  any Options or any Stock with respect to which
an Option may be or shall have been granted or exercised, or to qualify any such
Options or Stock under the  Securities  Act of 1933,  as  amended,  or any other
statute,  then the  Participant  shall  cooperate with the Company and take such
action as is necessary to permit  registration or  qualification of such Options
or Stock.

     15.2 Representations.  Unless the Company has determined that the following
representation is unnecessary,  each person  participating in an Offering may be
required by the  Company,  as a condition to the issuance of the shares of Stock
pursuant  to such  Offering to make a  representation  in writing (i) that he is
acquiring such shares for his own account for investment and not with a view to,
or for sale in connection  with, the distribution of any part thereof within the
meaning of the  Securities  Act of 1933,  and (ii) that  before any  transfer in
connection with the resale of such shares, he will obtain the written opinion of
counsel for the Company,  or other counsel acceptable to the Company,  that such
shares may be transferred  without  registration  thereof.  The Company may also
require  that  the  certificates   representing   such  shares  contain  legends
reflecting  the  foregoing.  To the  extent  permitted  by  law,  including  the
Securities Act of 1933, nothing herein shall restrict the right of a Participant
to sell the shares received in an open market transaction.

                                   ARTICLE XVI
                                 TAX WITHHOLDING

Company  shall have the power to require the  recipient of the Stock to remit to
the  Company  an  amount  sufficient  to  satisfy  federal,   state,  and  local
withholding tax requirements, if any.

     To the extent  permitted  by law,  each  person who is or shall have been a
member  of the  Board  or the  Committee  and the  Plan  Administrator  shall be
indemnified  and held harmless by the Company  against and from any loss,  cost,
liability,  or expense that may be imposed upon or reasonably incurred by him in
connection  with or resulting  from any claim,  action,  suit,  or proceeding to
which he may be a party or in which he may be  involved  by reason of any action
taken or failure to act under the Plan and  against and from any and all amounts
paid by him in settlement thereof,  with the Company's approval,  or paid by him
in satisfaction of judgment in any such action, suit, or proceeding against him,
provided he shall give the Company an opportunity, at its own expense, to handle
and  defend  the same  before he  undertakes  to handle and defend it on his own
behalf.  The foregoing  right of  indemnification  shall not be exclusive of any
other rights of  indemnification to which such persons may be entitled under the
Company's  certificate  of  incorporation  or  bylaws,  as a matter  of law,  or
otherwise, or any power that the Company or a Subsidiary Corporation may have to
indemnify them or hold them harmless.

                                  ARTICLE XVIII
                               REQUIREMENTS OF LAW

     18.1  Requirements of Law. The granting of Options  pursuant to an Offering
and the  issuance  of shares of Stock upon the  exercise  of an Option  shall be
subject to all applicable laws, rules, and regulations, and to such approvals by
any governmental agencies or national securities exchanges as may be required.

     18.2  Governing  Law.  The Plan,  and all  agreements  hereunder,  shall be
construed in accordance with and governed by the laws of the State of Colorado.

                                   ARTICLE XIX
                                  MISCELLANEOUS

     19.1  Designation  of  Beneficiary.   A  Participant  may  file  a  written
designation  of a  beneficiary  who  is to  receive  any  Stock  or  cash.  Such
designation  of  beneficiary  may be changed by the  Participant  at any time by
written  notice to the Plan  Administrator  of the Company.  Upon the death of a
Participant  and upon receipt by the Company of proof of identity and  existence
at the Participant's  death of a beneficiary validly designated by him under the
Plan, the Company shall deliver such Stock or cash to such  beneficiary.  In the
event of the death of a Participant and in the absence of a beneficiary  validly
designated under the Plan who is living at the time of such Participant's death,
the Company shall deliver such Stock or cash to the executor or administrator of
the estate of the Participant,  or if no such executor or administrator has been
appointed (to the knowledge of the Company), the Company, in its discretion, may
deliver such Stock or cash to the spouse or to any one or more dependents of the
Participant as the Company may designate.  No  beneficiary  shall,  prior to the
death of the  Participant by whom he has been designed,  acquire any interest in
the Stock or cash credited to the Participant under the Plan.

     19.2   Transferability.   Neither   payroll   deductions   credited   to  a
Participant's Account nor any rights with regard to the exercise of an Option or
to  receive  Stock  under the plan may be  assigned,  transferred,  pledged,  or
otherwise  disposed of in any way by the  Participant  other than by will or the
laws of descent  and  distribution.  Any such  attempted  assignment,  transfer,
pledge or other disposition shall be without effect, except that the Company may
treat such act as an election to withdraw funds in accordance with Section 9.2.

                                      -9A-
<PAGE>

     19.3 Use of Funds. All payroll  deductions  received or held by the Company
under this Plan may be used by the  Company  for any  corporate  purpose and the
Company shall not be obligated to segregate such payroll deductions.

     19.4 Effect of Plan. The provisions of the Plan shall,  in accordance  with
its terms,  be binding upon, and inure to the benefit of, all successors of each
Employee in the Plan, including,  without limitation, such Employee's estate and
the executors,  administrators or trustees thereof,  heirs and legatees, and any
receiver, trustee in bankruptcy or representative of creditors of such Employee.

                                   ARTICLE XX
                             EFFECTIVE DATE OF PLAN

     The Plan shall be effective on January 1, 1998.

     THIS EMPLOYEE  STOCK PURCHASE PLAN was adopted by the Board of Directors of
St. Mary Land & Exploration  Company on September 18, 1997, to be effective upon
adoption.

     The Plan requires  approval of the shareholders of the Company and shall be
submitted  to a vote for their  approval by the Board of Directors as soon as is
practicable.  If this Plan is not approved by vote of the shareholders within 12
months  after its adoption by the Board of  Directors,  it shall be void and any
Offering then in process shall terminate and all Participants  shall be returned
the balances in their  Accounts.  Participants  may retain,  however,  any Stock
already purchased  pursuant to a completed Offering and the Company shall deduct
and withhold from any amounts subsequently due and owing to the Participant such
federal,  state and local taxes as shall be required  pursuant to applicable law
based on failure of the Plan to qualify as an "employee  stock purchase plan" as
defined under Internal Revenue Code Section 423.
