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,  1998,  the  Company  had  estimated  net proved  reserves  of
approximately 8.6 MMBbls of oil and 132.6 Bcf of natural gas, or an aggregate of
184.3 BCFE (86%  proved  developed,  72% gas) with a PV-10  value  before tax of
$125.1 million.

         From January 1, 1994,  through  December 31,  1998,  the Company  added
estimated net proved  reserves of 270.0 BCFE at an average finding cost of $5.84
per BOE. The Company's  average annual  production  replacement  was 220% during
this five-year period.

         In 1998  production  increased  10% to a total of 33.1 BCFE, or average
daily  production  of 90.6 MMcf per day. The  Company's  1999 capital  budget of
approximately  $71.0 million includes $37.0 million for ongoing  development and
exploration  programs  in the core  operating  areas,  $25.0  million  for niche
acquisitions  of oil  and gas  properties  and  $9.0  million  for  higher-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 stockholder  value through  consistent
economic  growth in reserves and  production  and the resulting  increase in net
asset value per share, cash flow per share and earnings per share. A focused and
balanced  program of low to medium-risk  exploration  and  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  higher-risk,
large-target  exploration prospects has 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.

         St. Mary's  long-term  corporate  strategy focuses on growing value per
share, and not necessarily the absolute size of the Company. Management believes
that  independents  with equity  market  capitalizations  between  $250 and $600
million are best positioned to capitalize on  opportunities  in the domestic E&P
sector  and  therefore  to  realize  superior  returns  for their  stockholders.
Companies in this size range have critical mass and are able to sustain  quality
exploration,  development and niche acquisition programs that have a significant
impact on stockholder value.

                                      -4-
<PAGE>

         The Company will pursue  opportunities to monetize selected assets at a
premium and to repurchase  shares at  attractive  values in order to enhance the
growth in St. Mary's per share value while maintaining the market capitalization
of the  Company  within an optimal  size range.  St. Mary also will  continue to
focus its  resources  within  selected  basins in the U.S.  where the  Company's
expertise in geology, geophysics and drilling and completion techniques provides
competitive advantages.

         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 higher-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
possessing  over 20 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.  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.  Additionally,  the Company believes that it
can  continue  to expand  its  operations  without  the need to  proportionately
increase the number of employees.

         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  fracturing and  reservoir  stimulation
techniques,  and  specialized  logging  tools to maximize  the  potential of its
existing  properties.  During 1998, the Company  participated in 137 gross wells
with an 87% success rate and 52 recompletions with an 85% success rate.

         Large-Target Prospects. The Company generally invests approximately 15%
of its annual capital budget in higher-risk,  large-target exploration projects.
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 and Texas
during  1999,  including  prospects  at its  Stallion,  South  Horseshoe  Bayou,
Edgerly, Patterson, North Parcperdue and Carrier projects.

                                      -5-
<PAGE>

        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 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.

       St. Mary's strong balance sheet  positions the Company in 1999 to exploit
acquisition  opportunities  arising from dislocations  occurring  throughout the
upstream  oil and gas sector.  Many  over-leveraged  companies  are  expected to
divest  assets  during  the year in order to  reduce  their  debt  levels in the
adverse  climate of low prices and severely  limited access to new capital.  St.
Mary will  continue  to  emphasize  smaller  niche  acquisitions  utilizing  the
Company's technical expertise, financial flexibility and structuring experience.
Many  attractive  acquisition  candidates  are sourced in  cooperation  with St.
Mary's regional  offices where the local personnel have a detailed  insight into
emerging  opportunities.  Additionally,  the  Company is also  actively  seeking
larger  acquisitions of assets or companies that would afford  opportunities  to
expand the Company's existing core areas,  acquire  additional  geoscientists or
gain a  significant  acreage and  production  foothold in a new basin within the
United States.

         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
("Nance  Petroleum"),  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.

                                      -6-

Significant Developments Since December 31, 1997

         Oil and  Gas  Property  Sales.  In  order  to  continue  to  focus  and
rationalize its operations,  the Company sold certain non-strategic interests in
Oklahoma  for net  proceeds of  approximately  $22  million  and  various  minor
interests  in Canada  for net  proceeds  of $1.2  million.  Both of these  sales
occurred in December  1998.  The Company  realized a pre-tax gain on the sale of
these  properties of  approximately  $7.7 million.  To accelerate the receipt of
proceeds  from the  Canadian  property  sale,  the Company  obtained a letter of
credit  ("LOC")   guaranteeing  the  payment  of  Canadian  federal  income  tax
liabilities  for the Company  and its joint  venture  partners  in the  Canadian
properties. The Company expects the LOC to expire unused in 1999.

         Stock  Repurchase Plan. In August 1998 the Company's Board of Directors
authorized  a stock  repurchase  program  whereby  St.  Mary may  purchase  from
time-to-time,  in open market purchases or negotiated  sales, up to 1,000,000 of
its own common shares. The Company  repurchased a total of 147,800 of its common
shares during 1998 and an additional 35,000 shares to date in 1999.

         Acquisitions of Oil and Gas Properties. In 1998 the Company completed 6
acquisitions   of  oil  and  gas  properties  for  $4.2  million   comprised  of
supplemental  acquisitions  of $3.4 million in the Permian and Williston  basins
and  acquisitions of producing properties in Louisiana and the Anadarko Basin of
$800,000.

         Reserve Revisions and Writedowns.  The Company's year-end 1998 reserves
reflect  property  dispositions  of 39.6 BCFE which includes 2.8 BCFE of current
year  production,  discoveries and extensions of 40.8 BCFE,  acquisitions of 5.3
BCFE,  negative  price-related  revisions of 18.2 BCFE and a write-down  of 38.8
BCFE of  proved  reserves  at South  Horseshoe  Bayou,  of which  23.7 BCFE were
reclassified to the probable category.

         Writedown of Russian Joint Venture Receivable.  The Company reduced the
carrying  amount of the receivable  from Khanty  Mansiysk Oil Corporation to its
minimum  conversion value,  incurring a charge to operations of $4.6 million for
the year ended December 31, 1998 (see Item 2, International Operations).

         Writedown of  Investment  in Summo  Minerals  Corporation.  The Company
wrote  down  its  net  investment  in  Summo  Minerals  Corporation  to its  net
realizable  value in the  fourth  quarter of 1998 (see Item 2,  Non-Oil  and Gas
Activities).

     (1) Includes  reserves  associated  with  properties  in Colorado,  Kansas,
         Mississippi, New Mexico, Texas, Utah and Wyoming.

     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 43%
of the Company's  estimated net proved  reserves as of December 31, 1998 or 78.6
BCFE (77% proved  developed and 96% gas). The Company  participated  in 67 gross
wells and  recompletions in this region in 1998,  including 21  Company-operated
wells.

         The Company's  development and exploration  budget in the Mid-Continent
region for 1999 totals $22  million.  The  Company  plans to operate 29 drilling
wells  in the  Mid-Continent  region  during  1999 and to  utilize  two to three
drilling rigs  throughout  the year.  St. Mary also expects to participate in an
additional 10 to 20 wells to be operated by other entities.

         Anadarko   Basin.   The  Company's   long  history  of  operations  and
proprietary   geologic   knowledge   enable  the  Company  to  sustain  economic
development  and  exploration  programs  despite  periods  of  adverse  industry
conditions.  The Company is applying  state of the art  technology  in hydraulic
fracturing and innovative  well completion  techniques to accelerate  production
and associated cash flow from the region's tight gas  reservoirs.  St. Mary also
continues to benefit  from a continuing  consolidation  and  rationalization  of
operators in the basin. The Company periodically seizes attractive opportunities
to acquire properties from companies that have elected to discontinue operations
in the basin.  This trend is expected to accelerate during 1999 and to offer St.
Mary new  opportunities  as a result of the acute cost and capital  pressures in
the exploration and production sector.

         The Company works  aggressively  to control its operating  costs and to
enhance its full cycle  economics.  In December  1998 the Company  realized  net
proceeds  of $22  million on the sale of its  interests  in eight  fields in the
Anadarko Basin.  This sale was part of the Company's ongoing strategy to enhance
the  return  on its  portfolio  of  assets  through  the  opportunistic  sale of
non-strategic  properties  during  periods  in the market  when such  properties
command premium valuations.

         Drilling activities will focus on lower to medium-risk prospects in the
Granite  Wash and Red Fork  formations.  In  addition,  the Company  will devote
approximately  23%  of  its  Mid-Continent  capital  budget  to  deeper,  higher
potential  development  wells in the lower Morrow formation below 19,000 feet at
the NE  Mayfield  Field and in the  Hunton  and  Arbuckle  formations  at depths
between 16,000 and 18,000 at the SW Mayfield Field.

          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.  St.  Mary holds a 22%  working  interest  in the first
prospect  that will test a large 3-D anomaly that has been  interpreted  to be a
platform reef situated in the deeper portion of the East Texas Basin to the east
of the industry's existing pinnacle reef discoveries.  St. Mary and its partners
plan to spud the initial test well during the second half of 1999.

         South Louisiana Region. St. Mary's presence in south Louisiana dates to
the turn of the  century  when  the  Company's  founders  acquired  a  franchise
property in St. Mary Parish on the shoreline of the Gulf of Mexico. These 24,900
acres of fee lands  constitute  one of the Company's  most  valuable  assets and
yielded more than $6.9 million of gross oil and gas royalty revenue in 1998. The
south Louisiana region accounted for 6.6% of the Company's  estimated net proved
reserves as of December 31,  1998,  or 12.1 BCFE (86% proved  developed  and 63%
gas).

         The Company's diverse  activities in south Louisiana are managed by its
regional   3-person  office  in  Lafayette,   Louisiana,   and  include  ongoing
development and exploration programs in St. Mary, Cameron, Lafourche,  Jefferson
Davis,  Vermilion  and  Calcasieu  parishes.  Advanced  3-D seismic  imaging and
interpretation   techniques  are   revitalizing   exploration   and  development
activities  in the Miocene  trend of south  Louisiana.  St. Mary is applying the
latest  technologies  to unravel  the  region's  complex  geology  and to extend
exploratory drilling into deeper untested formations.

         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.

         The 1998  disappointments  at South  Horseshoe Bayou and at Atchafalaya
Bay discussed  below  underscore the risks inherent in the  exploration for deep
gas  reserves  in  south  Louisiana.  St.  Mary  evaluates  the  results  of its
exploration  efforts  based on full cycle  economic  returns  over a  multi-year
period and believes that exploration decisions should not be based solely on any
single year's results.

                                      -9-

         Fee Lands.  The Company owns 24,900  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 landowners' royalties,  to the Company from the Bayou Sale,
Horseshoe  Bayou and Belle  Isle  fields on its fee  lands  have  exceeded  $223
million.  St. Mary  currently  leases  14,419  acres of its fee lands and has an
additional  10,481 acres that are presently  unleased.  The Company's  principal
lessees are Texaco,  Vastar,  Cabot,  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 are sourced and trapped at depths below 16,000 feet.

     South  Horseshoe   Bayou  Project.   In  October  1995  the  Company  began
participation  as a working  interest  owner in its fee lands in St. Mary Parish
with a 25% working interest in this project; resulting in a net revenue interest
ranging from 36% to 40% due to its previously existing royalty position. The St.
Mary  Land &  Exploration  No.  1 well,  under a  turn-key  contract,  commenced
drilling  toward a target depth of 19,000 feet. In February 1996 this well began
encountering severe pressure and mechanical problems that could not be corrected
and in July 1996 the well was plugged without reaching total depth. The drilling
rig was skid and the  drilling  of a new well  commenced  on the same  site.  In
February 1997 the Company  announced a significant deep gas discovery at the St.
Mary Land & Exploration  No. 2 well.  This well was completed in the 17,300 foot
sand, and in January 1998 a  confirmation  well, the St. Mary Land & Exploration
No. 3, was  completed  in the same  interval.  In April  1998 the No. 2 well was
recompleted in the 17,900 foot sand and is currently  producing.  In August 1998
the No. 3 well was  shut-in as the result of  mechanical  problems  while it was
producing  approximately  33 MMcf per day.  Management  is currently  evaluating
whether to sidetrack or abandon the No. 3 well.

          At  year-end  the  Company  reclassified  23.7 BCFE of reserves to the
probable  category and wrote off 15.1 BCFE of reserves  due to  premature  water
encroachment  and  mechanical  problems.  Despite these  disappointments,  South
Horseshoe Bayou has generated  solid economic  returns for the Company and still
has significant remaining potential.  The two wells have produced 6.0 Bcf of gas
and 45 MBbls of oil, net to the Company's interest, through December 31, 1998.

         An untested fault block to the north of the existing production will be
drilled in 1999 as part of the Company's continuing  management and exploitation
of its fee lands.  Permitting of the St. Mary Land & Exploration  24-1 well (25%
working interest and  approximately 36% net revenue interest) is scheduled to be
completed  by April,  and  drilling  operations  are expected to commence in May
1999. (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. A  19,000-foot  test of a large 3-D  prospect  during 1998 was
unsuccessful  and the well was  completed  in a small  secondary  zone at 12,300
feet. The costs  associated with the drilling of this deep exploratory well were
expensed in 1998.

         Stallion  Prospect.  The Company's  Stallion  prospect  (31.25% working
interest) was spud in January 1999 and is currently  drilling  below 15,300 feet
toward a targeted total depth of approximately 17,800 feet. This 3-D prospect in
Cameron  Parish,  Louisiana  is  scheduled  to test a series of MA sands along a
major east-west growth fault that produces from the same interval to the east at
the Little Pecan Lake, Lac Blanc and North Freshwater Bayou fields.
(see "Large-Target Exploration Projects").

     Edgerly Prospect. St. Mary and its partners have completed a 30 square mile
3-D  survey on the  western  and  northern  flanks of the  Edgerly  salt dome in
Calcasieu Parish, Louisiana where a 16,000 acre leasehold position was assembled
during 1998. The Company has  identified a number of promising  anomalies on the
3-D survey and in 1999  expects to test several  Hackberry  prospects at shallow
depths  between  10,000 and 13,000  feet.  The  Company has an  approximate  35%
working  interest  in  the  Edgerly  prospect. (see  "Large-Target   Exploration
Projects").

         Patterson  Prospect.   The  Company's  Patterson  prospect  is  located
approximately  20 miles  north of the  Company's  fee lands in St.  Mary  Parish
within the lower Miocene  producing trend of south  Louisiana.  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.  The project was delayed  during
1998 due to the financial constraints of certain partners.  However, the partner
group is exploring alternatives with other parties and hopes to proceed with the
drilling of the 19,500-foot MA sand test by mid 1999.
(see "Large-Target Exploration Projects").

         North  Parcperdue  Prospect.  The Company has a 25% working interest in
the North  Parcperdue  prospect  located in  Vermilion  Parish.  The prospect is
targeting Marg Tex sands in a fault block with other productive shallow sands. A
re-entry and  sidetrack of the Phillips  Sweezy No. 1 well is scheduled to begin
in May 1999.  (see "Large-Target Exploration Projects").

         ArkLaTex  Region.  The  Company's  operations  in the ArkLaTex area are
managed by its 12-person  office in Shreveport,  Louisiana.  The ArkLaTex region
accounted for 24% of the Company's  estimated net proved reserves as of December
31, 1998, or 43.5 BCFE (92% proved  developed and 92% gas).  The Company's  1999
capital budget for the ArkLaTex region is $6.5 million.

         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. The Shreveport office's  successful  development
and  exploration  programs  have  derived  from a series  of niche  acquisitions
completed since 1992 totaling $10.8 million.  These  acquisitions  have provided
access to strategic holdings of undeveloped acreage and proprietary  packages of
geologic  and  seismic  data,  resulting  in an  active  program  of  additional
development and exploration.

         St. Mary's  holdings in the ArkLaTex  region are comprised of interests
in approximately 445 producing wells,  including 68 Company-operated  wells, and
interests  in leases  totaling  approximately  54,900  gross  acres and  mineral
servitudes totaling approximately 15,800 gross acres.

         Activities  in the  ArkLaTex  region  during 1998 focused on the phased
development  of  several  important  field  discoveries  made  by the  Company's
geoscientists  since 1994. At the Box Church Field in Limestone  County,  Texas,
the Company  completed  an  additional  eight wells in 1998,  bringing the field
total to 26 wells.  Four  additional  locations  are  planned  for  1999.  Gross
production  from the field has increased from 2.5 MMcf per day, when acquired in
1995,  to the  current  rate of 18 MMcf per day.  In 1999 the  Company  plans to
install additional  gathering systems,  compression and artificial lift upgrades
that are designed to sustain field  production at approximately 20 MMcf per day.
The Company operates the field and holds an average 58% working interest.  Total
cumulative gross field reserves are expected to exceed 100 Bcf of gas.

                                      -11-
<PAGE>

         Development  around the  Company's  1995  discovery at the  Haynesville
Field also continued in 1998 with St. Mary  participating  in the drilling of 14
new wells.  St. Mary and others have  drilled a total of 38 wells since the 1995
discovery.  The Company  operates 12 wells in the field and owns interests in an
additional 13 wells.

         In 1999 the Company is focused on the search for new  opportunities and
potential  analog fields in which to apply its  proprietary  geologic models and
production  techniques.  St. Mary believes that it is especially well positioned
to secure additional acquisitions in the ArkLaTex region during 1999 in the wake
of the  dislocations  and capital  shortages  being  experienced  by many of its
competitors.

         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% interest in Panterra,  and the managing  partner,
Nance Petroleum,  owns a 26% interest.  Nance Petroleum's  principal activity is
the  management  of  Panterra's  interests  in  the  Williston  Basin.  Panterra
currently  owns  interests in 62 fields within the basin's core  producing  area
including 134,000 gross acres, 78 Panterra-operated wells and 161 wells operated
by other parties.

         The Williston Basin region accounted for 14% of the Company's estimated
net proved reserves as of December 31, 1998, or 26.0 BCFE (97% proved  developed
and 88% oil). St. Mary has budgeted  approximately  $2.0 million as its share of
Panterra's 1999 development and exploration program.

         Panterra's  operations  are directed by senior  geoscientists  who have
devoted  their  careers  to the  development  of oil  and  gas  reserves  in the
Williston  Basin.  The  Company's  long-term  strategy  is  to  employ  advanced
technologies  to improve  drilling  results and  production in order to maximize
full cycle economics.  For instance,  Panterra has successfully used 3-D seismic
imaging to delineate structural and subtle stratigraphic features not previously
discernable using conventional exploration methods. This utilization of advanced
technologies by experienced  geoscientists  has helped  Panterra  achieve a 100%
success rate in its operated exploration and development program since 1991.

         During   periods  of  depressed  oil  prices  or  inflated   costs  the
partnership   has  the  financial   resources  to  capitalize  on   dislocations
experienced  by other  operators.  Panterra  uses these periods to replenish its
prospect  inventory,  to secure  attractively priced acquisitions and to conduct
additional 3-D seismic work and technical  studies in  anticipation  of cyclical
recovery in the industry.

         Panterra  plans to conduct six  additional  or extended  3-D surveys in
1999 over  existing  fields in the search for bypassed pay zones.  In addition a
detailed reservoir simulation of the Bainville Field is scheduled for completion
and will be used to evaluate secondary  recovery  opportunities in this existing
field.

         Permian Basin Region. The Permian Basin of New Mexico and west Texas is
the  Company's  newest area of  concentration.  The Permian  Basin area covers a
significant  portion of eastern New Mexico and  western  Texas and is one of the
major producing basins in the United States.  The basin includes hundreds of oil
fields undergoing secondary and enhanced recovery projects.  3-D seismic imaging
of  existing  fields  and  state-of-the-art   secondary  recovery  programs  are
substantially  increasing oil recoveries in the Permian Basin.  The optimization
of production and the careful control of operating costs are especially critical
in the prevailing low oil price environment.

                                      -12-
<PAGE>

         St. Mary's  holdings in the Permian Basin derive from a series of niche
property  acquisitions  that date  back to 1995.  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 Permian Basin region accounted
for 12% of the Company's  estimated net proved reserves as of December 31, 1998,
or 21.9 BCFE (91% proved developed and 77% oil).

         The  Company's   reservoir   engineers  have  identified  a  number  of
properties  where the project  economics of secondary  recovery  plans are still
acceptable under current prices. St. Mary's geoscientists have also warehoused a
number of high quality  prospects for which future drilling is contingent upon a
stabilization of oil prices above $15 per barrel.

         St. Mary  initiated a full-scale  multi-year  waterflood in 1998 at its
Parkway  (Delaware) Unit in Eddy County, New Mexico. The initial response to the
first phase of this waterflood has been excellent.  The Company's  operations in
the Permian  Basin  during 1999 will focus on the  expansion  of the  waterflood
project at Parkway and  additional  secondary  recovery  work at the Shugart and
Zuni fields.

         St. Mary also holds a 21.2% working interest in an unusual  30,450-acre
top lease in the North Ward Estes Field in Ward County,  Texas.  In August 2000,
all production and future  development and exploration  rights on this 50 square
mile  property  will  revert to the  ownership  and  control of St. Mary and its
partners.

         Large-Target   Exploration  Projects.  The  Company  generally  invests
approximately  15% 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  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 to apply the
latest technology  wherever  appropriate,  including 3-D seismic imaging, in its
prospect  development  and  evaluation  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.

International Operations

     In 1997 the Company  completed the sale or  disposition  of the majority of
its international investments. In 1998 the Company sold its remaining properties
in Canada.

     Russian Joint  Venture.  In February 1997, the Company sold its interest in
The Limited  Liability Company  Chernogorskoye  (the "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.  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 or on or after February 11, 2000, whichever occurs
first.  Uncertain  economic  conditions  in Russia  and lower  oil  prices  have
affected the  realizability  of the  convertible  receivable.  As a result,  the
Company  has  reduced  the  carrying  amount of the  receivable  to its  minimum
conversion value,  incurring a charge to operations of $4.6 million for the year
ended December 31, 1998.

         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 either  serve as operator or 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,  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.  This size of
acquisition  package  generally  attracts  less  competition  and is  where  the
Company's technical expertise,  financial flexibility and structuring experience
affords a competitive advantage.

         Faced with an overheated  acquisition  market where demand exceeded the
supply of  economically  sound  opportunities,  St. Mary chose to  conserve  its
capital   resources  in  1998  and  completed  only  $4.2  million  of  property
acquisitions. During the last five years the Company has closed over $85 million
of  niche  acquisitions  where  proprietary   geologic  knowledge  or  operating
expertise have afforded the Company a competitive advantage.

         The  economic  success of the  Company's  historical  acquisitions  has
resulted  from a focus on smaller,  negotiated  transactions  where St. Mary has
clearly identified  opportunities that maximize their value. St. Mary's teams of
geoscientists  and engineers  evaluate each  acquisition  to quantify  potential
opportunities  arising from proprietary geologic concepts or advanced production
technologies.  In addition,  the acquired production is hedged for periods up to
two years to protect the Company's return on its investment.

         In 1999 St. Mary has  reserved  $25 million of its capital  program for
property acquisitions. However, the Company has the financial capacity to commit
substantially greater resources to purchases should additional  opportunities be
identified.

         Weak  commodity  prices and  depressed  oil and gas stock  prices  have
precipitated an important  change in the  acquisition  market in early 1999. St.
Mary expects that quality  acquisitions will always command premium prices given
the inherent costs and risks  associated with developing new reserves.  However,
the  market  in  1999 is  expected  to  offer  favorable  opportunities  for the
relatively few financially strong companies able to capitalize on this depressed
market.

Reserves

         At December  31,  1998,  Ryder  Scott  Company,  independent  petroleum
engineers,  evaluated properties representing approximately 80% 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.

         The following table sets forth summary  information with respect to the
estimates of the Company's net proved oil and gas reserves for each of the years
in the  three-year  period ended  December 31, 1998,  as prepared by Ryder Scott
Company and St. Mary:

       (1) Reserve data attributable to the Company's Russian joint venture have
           been  excluded  from this table.  Effective  February 12,  1997,  the
           Company  sold  its  Russian   joint   venture.   See   "International
           Operations."
       (2) The Company's year-end 1998 reserves reflect property dispositions of
           39.6 BCFE,  discoveries and extensions of 40.8 BCFE,  acquisitions of
           5.3  BCFE,  negative  price-related  revisions  of  18.2  BCFE  and a
           write-down of 38.8 BCFE of proved reserves at South Horseshoe  Bayou,
           of which 23.7 BCFE were reclassified to the probable category.

         The present value of estimated  future net revenues before income taxes
of the  Company's  reserves was $125.1  million as of December  31,  1998.  This
present value is based on a benchmark of prices in effect at that date of $12.05
per barrel of oil (NYMEX)  and $1.855 per million  MMBtu of gas (Gulf Coast spot
price),  both of which are adjusted for transportation  and basis  differential.
These prices were 34 percent and 20 percent lower, respectively,  than prices in
effect at the end of 1997. Had the December 31, 1997,  pricing  assumptions been
applied,  the PV-10 value and net  reserves  would have been $193.2  million and
202.5 BCFE, respectively.

     (1)  Production  from South  Horseshoe  Bayou and sold Oklahoma  properties
          represented  18.1% and 6.5%  respectively,  or a total of 24.6% of the
          1998  production  total.  Management  expects  that the  1999  capital
          investment  program will partially  offset this  production  loss. 
     (2)  Includes  the  effects  of  the  Company's  hedging  activities.  (see
          "Management's  Discussion  and  Analysis of  Financial  Condition  and
          Results of Operations--Overview").

     The   Company   uses   financial   hedging    instruments,    primarily
fixed-for-floating  price swap  agreements  and no-cost collar  agreements  with
financial  counterparties,  to manage its exposure to  fluctuations in commodity
prices.  The Company also employs the use of  exchange-listed  financial futures
and options as part of its hedging program for crude oil.

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,
1998. 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.

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.  Summo's
common shares are listed on the Toronto Stock  Exchange  under the symbol "SMA."
The persistence of depressed  commodity prices and increased worldwide inventory
levels of copper have caused Summo's stock price to decline. Management believes
that this stock price  decline is not  temporary and that its value is impaired.
Consequently,  the  Company  wrote  down  its net  investment  in  Summo  to net
realizable value in the fourth quarter of 1998. Management believes the recorded
net investment is recoverable.

     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 ("LVMC"), 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 million senior debt financing in return for a 45%
interest in LVMC. The agreement is subject to certain  conditions  including the
finalization of the necessary project financing.

     The Company has agreed to provide  Summo with  interim  financing  of up to
$3.5 million for the Project in the form of a loan bearing interest at the prime
rate plus 1% due in June 1999.  As  security  for this loan,  Summo  pledged its
interest in LVMC to the Company in November 1998. As of December 31, 1998,  $2.9
million was outstanding under the note, and additional amounts totaling $188,000
have been  advanced to Summo under this loan to date in 1999.  At the  Company's
option,  the  principal  amounts  advanced  by the  Company  under  the note are
convertible  into shares of Summo  common stock at a defined  conversion  price.
Upon  finalization of the necessary  project financing for LVMC, the Company may
elect  to deem  the  outstanding  principal  amount  of the  note  as a  capital
contribution in partial  satisfaction of its capital commitments as set forth in
the May 1997  agreement.  Accrued  interest  on the loan will be forgiven if the
Company makes this election.

     In September 1998 Summo received final  regulatory  approval to develop the
Project.  Future  development  and financial  success of the Project are largely
dependent on the market price of copper,  which is  determined  in world markets
and is subject to significant fluctuations.  Current copper prices have declined
to ten-year lows and do not justify  construction and development of the Project
at this time.  Management  believes that copper prices will recover and that the
Project will have  considerable  value at that time. The Company has the ability
to fund the carrying costs of the property and the intent to retain its interest
in the  Project  until  copper  prices  do  recover.  However,  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  1998  no  individual  customer  accounted  for  10% or  more of the
Company's  total  oil and gas  production  revenue.  During  1997 two  customers
individually  accounted for 10.6% and 10.2% of the  Company's  total oil and gas
production revenue.

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.  Initiatives to further  regulate the disposal
of oil and gas  wastes  at the  federal,  state  and local  level  could  have a
material 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. 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 such event 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 the 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  affect 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, 1998, the Company had 110 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  and  administrative  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  1,100  square  feet  in  Lafayette,
Louisiana. The Company believes that its current facilities are adequate.

       (1) EBITDA is defined as earnings  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 natural gas and
crude oil with  operations  focused in five core  operating  areas in the United
States:  the Mid-Continent  region;  the ArkLaTex region;  south Louisiana;  the
Williston Basin; and the Permian Basin.

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

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

     The Company's presence in south Louisiana includes active management of its
fee lands from which  significant  royalty income is derived.  Royalty  revenues
from the fee lands were $6.9, $8.8 and $8.1 million for the years 1998, 1997 and
1996, respectively. 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
discovery  on its fee  lands at  South  Horseshoe  Bayou  in early  1997 and the
successful confirmation well in early 1998 proved that significant accumulations
of gas are sourced and trapped at depths below  16,000 feet.  In August 1998 one
of the wells in the South Horseshoe Bayou project experienced shut-in production
due to  mechanical  problems.  These  mechanical  problems and  premature  water
encroachment  caused the Company to reduce the project's proved reserves by 38.8
BCFE, of which 23.7 BCFE were  reclassified to the probable reserve category and
15.1 BCFE were written off. An untested fault block to the north of the existing
production will be drilled at South Horseshoe Bayou in 1999.

                                      -28-

     St.  Mary  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 it has specialized geologic knowledge or operating
experience  has enabled it to acquire  attractively-priced  and  under-exploited
properties.

     The results of operations  include several  significant  acquisitions  made
during recent years and their subsequent further  development by the Company. In
1996 the Company  purchased a 90% interest in the producing  properties of Siete
Oil & Gas Corporation for $10.0 million.  A series of follow-on  acquisitions of
smaller interests in these properties during 1997 and 1998 totaled $5.8 million.
The properties  purchased from Siete  solidified a new core area of focus in the
Permian  Basin of New Mexico  and west  Texas.  St.  Mary  purchased  additional
interests  in its  Elk  City  Field  located  in  Oklahoma  in 1996  from  Sonat
Exploration  Company  for $5.7  million.  In 1997 the  Company  acquired  an 85%
working interest in certain Louisiana properties of Henry Production Company for
$3.9 million.  Also in 1997 the Company purchased the interests of Conoco,  Inc.
in the Southwest Mayfield area in Oklahoma for $20.6  million.  In late 1998 St.
Mary, through Panterra, acquired the interests of Texaco, Inc. in several fields
in the Williston Basin for $2.1 million.

     The Company pursues  opportunities to monetize selected assets at a premium
and as part of its continuing  strategy to focus and rationalize its operations.
In 1996 and 1997 the Company sold its  interests in Wyoming for $2.9 million and
its  non-operated  interests in south Texas for $5.4 million,  respectively.  In
late 1998 St.  Mary sold a package of  non-strategic  properties  in Oklahoma to
ONEOK Resources Company ("ONEOK") for $22.2 million and sold its remaining minor
interests in Canada for $1.2 million.

     St. Mary has two principal equity investments,  Summo Minerals  Corporation
("Summo")  and,  until early 1997,  the  Company's  Russian joint  venture.  The
Company accounts for its investments in Summo and The Limited  Liability Company
Chernogorskoye  ("the  Russian  joint  venture")  under the  equity  method  and
includes its share of the income or loss from these entities in its consolidated
results of  operations.  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.

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

     In June 1998 the Company's  stockholders approved an increase in the number
of authorized shares of the Company's common stock from 15,000,000 to 50,000,000
shares.

                                      -29-
<PAGE>

     In  August  1998  the  Company's  Board  of  Directors  authorized  a stock
repurchase  program  whereby St. Mary may purchase  from  time-to-time,  in open
market  transactions  or  negotiated  sales,  up to  1,000,000 of its own common
shares. The Company has repurchased stock under this plan in 1998 and 1999.

     The  Company  seeks  to  protect  its rate of  return  on  acquisitions  of
producing  properties  by hedging up to the first 24 months of an  acquisition's
production  at  prices  approximately  equal  to  those  used  in the  Company's
acquisition  evaluation and pricing model.  The Company also  periodically  uses
hedging  contracts to hedge or otherwise  reduce the impact of oil and gas price
fluctuations on production 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 45% of its estimated 1999 gas
production at an average fixed price of $2.10 per MMBtu, approximately 9% of its
estimated  1999 oil  production  at an average fixed price of $15.11 per Bbl and
approximately  8% of its estimated 2000 oil production at an average fixed price
of $14.76 per Bbl.  The Company has also  purchased  options  resulting in price
collars on approximately 7% of the Company's  estimated 1999 gas production with
price ceilings  between $2.00 and $2.63 per MMBtu and price floors between $1.50
and $1.90 per MMBtu.

         Oil and Gas  Production  Revenues.  Oil  and  gas  production  revenues
decreased $5.1 million, or 7% to $70.6 million in 1998 compared to $75.8 million
in  1997.  Oil  production  volumes  increased  7% and  gas  production  volumes
increased 11% in 1998  compared to 1997.  Average net daily  production  reached
15.1  MBOE in 1998  compared  to 13.7  MBOE in 1997.  This  production  increase
resulted  from new  properties  acquired and drilled  during 1998 and late 1997.
Major  acquisitions  affecting the  production  increase  included the Southwest
Mayfield  properties  in  Oklahoma  purchased  from  Conoco  and  the  Louisiana
properties  purchased from Henry Production  Company in 1997, the acquisition of
certain producing  properties in Texas from Stroud  Exploration in 1998, and the
additional  interests  purchased in the Siete  properties  during 1997 and 1998.
Successful  drilling results in the South Horseshoe Bayou and Haynesville fields
in Louisiana,  the Box Church Field in Texas and the Company's Oklahoma drilling
program also  contributed  to the 1998  production  increase.  These  production
increases were only slightly offset by the sale of certain  Oklahoma  properties
to ONEOK Resources Company in late 1998.

         The average  realized  oil price for 1998  decreased  31% to $12.98 per
Bbl, while average realized gas prices decreased 9% to $2.13 per Mcf, from their
respective  1997  levels.  The  Company  hedged  approximately  20.1% of its oil
production  for 1998 or 257 MBbls at an  average  NYMEX  price of  $19.423.  The
Company realized a $435,000 increase in oil revenue or $.34 per Bbl for 1998 on
these  contracts  compared to a $293,000  decrease or $.25 per Bbl in 1997. The
Company  also  hedged  45.3% of its 1998 gas  production  or 11,520  MMBtu at an
average indexed price of $2.343. The Company realized a $1.4 million increase in
gas revenues or $.06 per Mcf for 1998 from these hedge contracts  compared to a
$2.9 million decrease in gas revenues or $.13 per Mcf in 1997.

         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  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 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  Costs.  Oil and gas production costs consist of
lease operating expense and production  taxes.  Total production costs increased
$1.7  million,  or 11% in 1998 to $17.0  million  compared with $15.3 million in
1997,  while total oil and gas  production  costs per BOE  increased  only 1% to
$3.08 in 1998 compared with $3.05 in 1997. 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.

         Depreciation,  Depletion,  Amortization  and Impairment.  Depreciation,
depletion and  amortization  expense  ("DD&A")  increased $6.5 million or 36% to
$24.9  million in 1998  compared  with  $18.4  million  in 1997.  This  increase
resulted  from  increased  production  volumes of new  properties  acquired  and
drilled  in 1998 and late  1997.  Significant  contributors  were the  Southwest
Mayfield  properties  acquired from Conoco in the fourth quarter of 1997 and the
reduction  of proved  reserves at South  Horseshoe  Bayou.  Decreases in reserve
volumes  caused by the adverse  impact of low oil prices in the Williston  Basin
and mechanical  problems at South Horseshoe  Bayou also  contributed to the DD&A
increase.  DD&A expense per BOE increased 23% to $4.52 in 1998 compared to $3.67
in 1997 due to higher  drilling  and  acquisition  costs per BOE and the factors
mentioned  above.  Impairment of proved oil and gas properties  increased  $12.3
million  to $17.5  million in 1998  compared  with $5.2  million in 1997.  These
charges mainly resulted from a decline in the value of the Company's oil and gas
reserves  brought  about by lower prices at December 31, 1998,  the reduction of
proved reserves at South Horseshoe Bayou, a $6.2 million charge  associated with
the  unsuccessful  deep  test at the  Company's  Atchafalaya  prospect  in south
Louisiana and marginal and unsuccessful  development  wells drilled in Oklahoma,
Texas and Louisiana.

         Depreciation,   depletion  and  amortization   expense  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.

         Abandonment  and  impairment  of  unproved  properties  increased  $2.4
million or 115% to $4.5 million in 1998  compared to $2.1 million in 1997 due to
additional impairments taken during 1998. 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.

         Exploration. Exploration expense increased $4.9 million or 71% to $11.7
million for 1998  compared  with $6.8  million in 1997  primarily  due to higher
geological and  geophysical  costs and the drilling of ten exploratory dry holes
during 1998 in the Mid-Continent and south Louisiana regions, compared to better
exploratory  drilling  results in 1997. The payment of $795,000 in delay rentals
for the Company's Atachafalaya prospect area during 1998 also contributed to the
increase in exploration  expense.  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.

         General  and  Administrative.   General  and  administrative   expenses
decreased $548,000 or 7% in 1998 compared to 1997 primarily due to the reduction
of expenses related to the Company's Stock Appreciation  Rights ("SAR") plan and
a  reduction  in  charitable  contributions  which is based on  pre-tax  income.
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 SAR plan.

         Other  operating  expenses  primarily  consist  of  legal  expenses  in
connection  with ongoing oil and gas  activities  and oversight of the Company's
mining investments. This expense decreased $140,000 or 50% in 1998 compared with
1997,  primarily due to decreased  activity in the pending litigation that seeks
to  recover  damages  from  the  drilling  contractor  for the St.  Mary  Land &
Exploration  No.  1 well at  South  Horseshoe  Bayou.  Other  operating  expense
increased  $203,000 to $281,000 in 1997  compared  with 1996,  primarily  due to
legal expenses  associated  with the pending  litigation for the St. Mary Land &
Exploration No. 1 well.

         Equity in Income of Russian Joint  Venture.  The Company  accounted for
its investment in the Russian joint venture under the equity method and included
its share of income or loss from the venture in its results of  operations up to
the point of sale. The equity in the net income of the Russian joint venture was
$201,000 in 1997 and $1.7  million in 1996.  As  discussed  under  Outlook,  the
Company sold this  investment  in February  1997  resulting in a partial year of
equity income recorded in 1997.

                                      -33-
<PAGE>

         Equity in Loss of Summo Minerals Corporation.  The Company accounts for
its  investment  in Summo  under the  equity  method and  includes  its share of
Summo's income or loss in its results of operations.  The equity in the net loss
of Summo was $661,000 in 1998, $526,000 in 1997, and $457,000 in 1996. Increased
losses  are due to  general  and  administrative  expenses  associated  with the
expansion  of  Summo's  Denver  office  beginning  in 1996 and with the  appeals
process for  permitting  of the Lisbon  Valley  Copper  Project.  The  Company's
ownership in Summo was 37% in 1998 and 1997 and was 49% in 1996.

         Non-Operating  Income and Expense. Net interest and other non-operating
expense  increased  $928,000 to $1.0 million in 1998 compared to $99,000 in 1997
due primarily to increased borrowings in 1998 to fund capital expenditures,  and
to lower borrowings in 1997 resulting from cash received from the sale of common
stock. 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.

         Income Taxes.  Income taxes  provided a net benefit of $5.4 million for
1998 resulting in an effective tax rate of 38%. The benefit  reflects the effect
of the book net operating loss and the  compounded  effect of Section 29 credits
incurred in years when the Company  reports a book loss.  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.  The  expense  amounts  in 1997 and 1996  reflect
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.

         State tax  expense  was  $24,000 in 1998,  $1.6  million  in 1997,  and
$700,000 in 1996. The significant  decrease in state taxes in 1998 was caused by
the book net operating loss which resulted from Louisiana  activity in the South
Horseshoe  Bayou and  Atchafalaya Bay prospects plus the effects on Colorado and
other  states of the  Russian  and Summo  writedowns.  Louisiana  taxes for 1997
increased  significantly as a result of higher  Louisiana net income,  primarily
from royalty income,  and working interest income from South Horseshoe Bayou and
the Henry Production Company acquisition during 1997.

         Net Income.  Net loss for 1998 was $8.8 million  compared to net income
of $23.1  million for 1997. A 9% reduction in gas prices and a 31%  reduction in
oil  prices  were  only  partially  offset  by an 11%  percent  increase  in gas
production  volumes and a 7% increase  in oil  production  volumes for the year.
This  resulted  in a  $5.1  million  or 7%  reduction  in  oil & gas  production
revenues.  Gains on sales of proved  properties  of $7.7  million were offset by
impairments  of proved  and  unproved  properties  and  increased  DD&A  expense
resulting  from lower  reserve  values;  writedowns  of the Russian  convertible
receivable  and the  Company's  investment  in  Summo  Minerals;  and  increased
exploration expense brought about by unsuccessful exploration projects.

         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  gains net of income taxes from the sale of
discontinued  real estate of $34,000 in 1998,  $488,000 in 1997 and  $159,000 in
1996, respectively.

Liquidity and Capital Resources

         The  Company's  primary  sources of liquidity  are the cash provided by
operating  activities,  debt financing,  sales of  non-strategic  properties 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  $2.3 million or 5% to $45.4 million in 1998 compared to $43.1 million
in 1997. A significant  decrease in accounts receivable resulting from lower oil
and gas prices and reduced  drilling  activity was partially offset by increases
in prepaid  expenses and cash paid for interest.  Net cash provided by operating
activities  increased  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.

     The Company made cash payments of  approximately  $363,000 in 1998 and $1.6
million in 1997 in satisfaction of liabilities  previously accrued under the SAR
plan.

         Net cash used in investing activities decreased $30.5 million or 45% in
1998 to $37.0  million  compared  to $67.5  million  in 1997.  The  decrease  is
primarily due to a $10.1 million  increase in proceeds from sales of oil and gas
properties in 1998, including the sale of the Russian joint venture in 1997, and
a  decrease  of  $23.1  million  in cash  paid for  acquisitions  of oil and gas
properties in 1998. Total 1998 capital expenditures,  including  acquisitions of
oil and gas properties,  decreased $22.9 million or 28% to $58.6 million in 1998
compared to $81.5 million in 1997.

         Net cash used in investing activities increased $22.3 million or 49% in
1997 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 in 1997 compared to
$48.5 million in 1996.

         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.  A portion of the proceeds from sales of oil and gas properties in
1998 were also applied to  acquisitions  of oil and gas properties in 1999 under
tax-free  exchanges.  In a tax-free  exchange of properties the tax basis of the
sold property carries over to the acquired  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 acquired property is sold
or abandoned.

         Net cash provided by (used in)  financing  activities  decreased  $35.8
million to net cash used of $7.7 million  compared to net cash provided of $28.1
million in 1997.  The  decrease in cash  provided  was due to the $51.2  million
received  in 1997 from the sale of common  stock  compared  to only  $173,000 in
1998. This change was partially  offset by a $3.2 million  decrease in long-term
debt in 1998  compared to a $21.0  million  decrease in 1997.  The Company  also
spent $2.5 million in 1998 to repurchase shares of its own common stock.

                                      -35-
<PAGE>

         Net cash  provided by financing  activities  increased  $5.5 million to
$28.1 million in 1997 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.  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.

         The  Company  had $7.8  million  in cash and cash  equivalents  and had
working capital of $9.8 million as of December 31, 1998 compared to $7.1 million
in cash and cash  equivalents and working capital of $9.6 million as of December
31,  1997.  A decrease  in  accounts  receivable  was offset by an  decrease  in
accounts payable and a slight increase in cash and cash equivalents.

         Credit  Facility.  On June 30,  1998,  the Company  entered  into a new
long-term  revolving credit agreement that replaced the agreement dated March 1,
1993 and amended in April  1996.  The new credit  agreement  specifies a maximum
loan amount of $200.0  million and had an initial  aggregate  borrowing  base of
$115.0 million. The lender may periodically re-determine the aggregate borrowing
base  depending upon the value of the Company's oil and gas properties and other
assets.  In December 1998 the borrowing base was reduced by the lender to $105.0
million as a result of the sale of certain  producing  properties in Oklahoma to
ONEOK.  The accepted  borrowing base was $40.0 million at December 31, 1998. The
credit  agreement  has a maturity  date of December  31,  2005,  and  includes a
revolving  period that matures on December  31,  2000.  The Company can elect to
allocate up to 50% of available  borrowings  to a short-term  tranche due in 364
days. The Company must comply with certain  covenants  including  maintenance of
stockholders'  equity  at  a  specified  level  and  limitations  on  additional
indebtedness. As of December 31, 1998 and 1997, $10.5 million and $14.5 million,
respectively,  was outstanding  under this credit  agreement.  These outstanding
balances  accrue  interest at rates  determined by the  Company's  debt to total
capitalization  ratio.  During the revolving  period of the loan,  loan balances
accrue interest at the Company's  option of either (a) the higher of the Federal
Funds  Rate  plus  1/2% or the  prime  rate,  or (b)  LIBOR  plus  1/2% when the
Company's  debt to total  capitalization  is less than 30%,  up to a maximum  of
either (a) the higher of the Federal Funds Rate plus 5/8% or the prime rate plus
1/8%, or (b) LIBOR plus 1-1/4% when the Company's  debt to total  capitalization
is equal to or greater than 50%.

         Panterra,  in which the Company has a 74% general partnership interest,
has a  separate  credit  facility  with a  $21.0  million  borrowing  base as of
December  31,  1998,  and $12.0  million  and $11.0  million  outstanding  as of
December 31, 1998 and 1997,  respectively.  In June 1997,  Panterra entered into
this credit agreement replacing a previous agreement due March 31, 1999. The new
credit  agreement   includes  a  revolving  period  converting  to  a  five-year
amortizing loan on June 30, 2000.  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%.

         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.

                                      -36-
<PAGE>

         In June 1998 the  Company's  stockholders  approved  an increase in the
number of  authorized  shares of the Company's  common stock from  15,000,000 to
50,000,000 shares.

         In August 1998 the  Company's  Board of  Directors  authorized  a stock
repurchase  program  whereby St. Mary may purchase  from  time-to-time,  in open
market  transactions or negotiated  sales, up to 1,000,000 of its common shares.
During  1998 the  Company  repurchased  a total of 147,800  shares of its common
stock under the program for $2.5 million at a  weighted-average  price of $16.71
per share. In early 1999 the Company repurchased an additional 35,000 shares for
$15.00 per share.  Management anticipates that additional purchases of shares by
the Company  may occur as market  conditions  warrant.  Such  purchases  will be
funded  with  internal  cash  flow and  borrowings  under the  Company's  credit
facility.

         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.

     (a) In February  1997,  the Company sold its interest in the Russian  joint
         venture.

         The Company's  total costs incurred in 1998 decreased  $31.4 million or
35% compared to 1997.  Proved property  acquisitions  decreased $23.1 million in
1998.  In December 1998 Panterra  acquired  certain  properties in the Williston
Basin for $2.8 million, of which the Company's share was $2.1 million. Follow-on
acquisitions  relating  to  interests  purchased  in the  Permian  Basin in 1996
amounted to $1.2 million in 1998, and certain  properties were acquired in Texas
for $510,000.  Several  smaller  acquisitions  were also  completed  during 1998
totaling $390,000. The Company spent $53.7 million in 1998 for unproved property
acquisitions and domestic  exploration and development compared to $61.9 million
in 1997.

                                      -37-

         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.

         Outlook. The Company believes that its existing capital resources, cash
flows from  operations  and  available  borrowings  are  sufficient  to meet its
anticipated capital and operating requirements for 1999.

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

         The  Company  anticipates  spending  approximately  $71.0  million  for
capital and exploration  expenditures  in 1999 with $37.0 million  allocated for
ongoing  exploration and development in its core operating areas,  $25.0 million
for  niche   acquisitions   of  producing   properties   and  $9.0  million  for
large-target, higher-risk exploration and development.

         Anticipated ongoing  exploration and development  expenditures for each
of the Company's core areas include $22.0 million in the  Mid-Continent  region,
$6.5 million in the ArkLaTex  region,  $2.0 million in the  Williston  Basin and
$6.5 million allocated within the Permian Basin and south Louisiana regions.

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

         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  borrowing  capability  and  the  success  of its
development  and exploratory  activity which could lead to funding  requirements
for further development.

         The Company continuously evaluates opportunities in the marketplace for
oil  and  gas  properties  and,  accordingly,  may be a  buyer  or a  seller  of
properties at various times.  St. Mary will continue to emphasize  smaller niche
acquisitions utilizing the Company's technical expertise,  financial flexibility
and structuring  experience.  In addition,  the Company is also actively seeking
larger  acquisitions of assets or companies that would afford  opportunities  to
expand the Company's existing core areas, to acquire additional geoscientists or
to gain a significant  acreage and production foothold in a new basin within the
United States.

         The Company,  through a subsidiary,  owns 9.9 million  shares or 37% of
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.  Summo's common shares are listed on
the Toronto stock exchange under the symbol "SMA".  The persistence of depressed
commodity prices and increased  worldwide inventory levels of copper have caused
Summo's  stock  price to  decline.  Management  believes  that this stock  price
decline  is not  temporary  and that its value is  impaired.  Consequently,  the
Company wrote down its net  investment in Summo to net  realizable  value in the
fourth  quarter of 1998.  Management  believes the recorded  net  investment  is
recoverable.

         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 ("LVMC"), 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 million senior debt financing in return for a 45%
interest in LVMC. The agreement is subject to certain  conditions  including the
finalization of the necessary project financing.

         The Company has agreed to provide Summo with interim financing of up to
$3.5 million for the Project in the form of a loan bearing interest at the prime
rate plus 1% due in June 1999.  As  security  for this loan,  Summo  pledged its
interest in LVMC to the Company in November 1998. As of December 31, 1998,  $2.9
million was outstanding under the loan, and additional amounts totaling $188,000
have been  advanced to Summo under this loan to date in 1999.  At the  Company's
option,  the  principal  amounts  advanced  by the  Company  under  the note are
convertible  into shares of Summo  common stock at a defined  conversion  price.
Upon  finalization of the necessary  project financing for LVMC, the Company may
elect  to deem  the  outstanding  principal  amount  of the  note  as a  capital
contribution in partial  satisfaction of its capital commitments as set forth in
the May 1997  agreement.  Accrued  interest  on the loan will be forgiven if the
Company makes this election.

         In September 1998 Summo received final  regulatory  approval to develop
the Project. Future development and financial success of the Project are largely
dependent on the market price of copper,  which is  determined  in world markets
and is subject to significant fluctuations.  Current copper prices have declined
to ten-year lows and do not justify  construction and development of the Project
at this time.  Management  believes that copper prices will recover and that the
Project will have  considerable  value at that time. The Company has the ability
to fund the carrying costs of the property and the intent to retain its interest
in the  Project  until  copper  prices  do  recover.  However,  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  interest in the 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.  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 or on or after March 10, 2000,  whichever  occurs
first.  Uncertain  economic  conditions  in Russia  and lower  oil  prices  have
affected the carrying value of the  convertible  receivable.  Consequently,  the
Company reduced the carrying amount of the receivable to its minimum  conversion
value during 1998, incurring a pre-tax charge to operations of $4.6 million.

         Impact of the Year  2000  Issue.  The  following  Year 2000  statements
constitute a Year 2000 Readiness  Disclosure within the meaning of the Year 2000
Information and Readiness Disclosure Act of 1998.

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

         The Company's  approach to determining and mitigating the impact on the
Company of Year 2000 compliance issues is comprised of five phases:

     i) Review  and  assessment  of all  internal  information  technology  (IT)
        systems and significant non-IT systems for Year 2000 compliance;
    ii) Identify and  prioritize  systems with Year 2000  compliance  issues;
   iii) Repair or replace and test non-Year 2000 compliant systems;
    iv) Survey  and  assess  the  Year  2000  readiness  of the  Company's
        significant  vendors, suppliers, purchasers and  transporters of oil and
        natural  gas;  and, 
     v) Design and  implement  contingency plans for those systems, if any, that
        cannot be made Year 2000 compliant before December 31, 1999.

         The Company completed phases i) and ii) of its plan by August 1998, and
identified the systems  requiring repair or replacement in order to be Year 2000
compliant. This review and assessment was completed using outside consultants as
well as Company personnel. The Company determined that of its major systems, the
software it uses for reservoir engineering,  its telephone system, a significant
number of the  personal  computers  used by Company  personnel  and the computer
system used by Panterra should be updated or replaced.

         Phase iii) of the Company's plan of repair and  replacement of non-Year
2000 compliant systems is approximately  90% complete.  The telephone system and
personal  computers  have been  replaced with Year 2000  compliant  hardware and
software as part of the Company's ongoing upgrade program. The Company purchased
a  Year  2000  compliant  release  of  the  reservoir   engineering  system  and
anticipates conversion to and testing of the new system in the second quarter of
1999.  In the fourth  quarter of 1998  Panterra  licensed a Year 2000  compliant
system and  converted to the new system in January  1999.  The systems that have
been either  upgraded or replaced  will be further  tested to confirm their Year
2000 compliance. This testing is planned for completion in the second quarter of
1999. The Company  presently  believes that other less significant IT and non-IT
systems can be upgraded to mitigate any Year 2000 issues with  modifications  to
existing software or conversions to new systems. Modifications or conversions to
new systems 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.

                                      -40-
<PAGE>

         Under   phase  iv)  of  the  plan,   the   Company   initiated   formal
communications  with its  significant  vendors,  suppliers  and  purchasers  and
transporters of oil and natural gas to determine the extent to which the Company
is vulnerable to those third parties'  failures to remediate their own Year 2000
issues.  The  process of  collecting  information  from these  third  parties is
approximately 40% complete.  All of the responses  received to date are positive
in assuring that the respondents  will be Year 2000 compliant on a timely basis.
Completion of phase iv) of the plan is anticipated in the third quarter of 1999.
Until this phase of the plan is complete, management cannot currently predict if
third party compliance issues will materially  affect the Company's  operations.
There can be no  assurance  that the  systems  of these  third  parties  will be
converted  timely, or that a failure to remediate Year 2000 compliance issues by
another company would not have a material adverse effect on the Company.

         Phase v) of the Company's Year 2000 plan, the design and implementation
of contingency  plans for those  systems,  if any, that cannot be made Year 2000
compliant before December 31, 1999, will be addressed in the last half of 1999.

         Through December 31, 1998, the Company has spent approximately $450,000
on its Year 2000 efforts.  This includes the costs of consultants as well as the
cost of repair or replacement of  non-compliant  hardware and software  systems.
Additional  costs to complete the Company's plan are estimated at  approximately
$50,000.  The  Company  has not  specifically  tracked  its  internal  costs  of
addressing the Year 2000 issue. However, management does not believe these costs
to be material.

         The  Company  has  not  completed  a  comprehensive   analysis  of  the
operational  problems and costs that would be  reasonably  likely to result from
the Company or its significant third parties' failure to timely complete efforts
to remediate Year 2000 issues.  Potential "worst case" impacts could include the
inability of the Company to deliver its production to, or receive  payment from,
third parties purchasing or transporting the Company's production; the inability
of third party  vendors to provide  needed  materials or services to the Company
for ongoing or future exploration,  development or producing operations; and the
inability  of the Company to execute  financial  transactions  with its banks or
third parties whose systems fail or malfunction.

         The  Company  currently  has no  reason  to  believe  that any of these
contingencies will occur or that its principal  vendors,  customers and business
partners  will not be Year 2000  compliant.  However,  there can be no assurance
that the Company will be able to identify and correct all Year 2000  problems or
implement a satisfactory contingency plan. Therefore,  there can be no assurance
that the Year 2000 issue will not  materially  impact the  Company's  results of
operations or adversely  affect its  relationships  with vendors,  customers and
other business partners.

Accounting Matters

         In June 1997, the Financial  Accounting Standards Board ("FASB") issued
Statement of Financial Accounting Standards ("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
operates  predominantly  in one  industry  segment,  which  is the  exploration,
development  and  production  of natural  gas and crude oil,  and the  Company's
operations are conducted entirely in the United States

         In June 1998, the FASB issued SFAS No. 133,  "Accounting for Derivative
Instruments and Hedging Activities," effective for all fiscal quarters of fiscal
years beginning after June 15, 1999. The Statement  requires companies to report
all  derivatives  at fair value as either  assets or  liabilities  and bases the
accounting  treatment  of the  derivatives  on the  reasons an entity  holds the
instrument.  The Company is currently  reviewing the effects this Statement will
have  on  the  financial   statements  in  relation  to  the  Company's  hedging
activities.

Effects of Inflation and Changing Prices

         Within  the United  States  inflation  has had a minimal  effect on the
Company. The Company cannot predict the future extent of any such effect.

         The  Company's  results of  operations  and cash flows are  affected by
material changes in oil and gas prices. Oil and gas prices are strongly impacted
by global  influences on the supply and demand for petroleum  products.  Oil and
gas prices are further impacted by the quality of the oil and gas to be sold and
the location of the  Company's  producing  properties in relation to markets for
the  products.  Oil and gas price  increases or decreases  have a  corresponding
effect on the Company's revenues from oil and gas sales. Oil and gas prices also
affect the prices  charged for  drilling  and related  services.  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.  Also, 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.

         Material  changes in oil and gas prices  affect the  current and future
value of the Company's estimated proved reserves and the borrowing capability of
the Company,  which is largely based on the value of such proved  reserves.  Oil
and gas price changes have a corresponding  effect on the value of the Company's
estimated  proved  reserves and the  available  borrowings  under the  Company's
credit facility.

         During the first half of 1998 the  Company  experienced  an increase in
the cost of drilling and related services  resulting from shortages in available
drilling rigs, drilling and technical personnel, supplies and services. However,
service costs stabilized about mid-year 1998 and have begun to decline. The last
half of 1998 was  characterized by historically low oil prices and weakening gas
markets.  Capital has left the oil and gas industry and has caused a significant
drop in the number of working drilling rigs.  Consequently,  in early 1999 there
is an abundance of available  drilling  rigs,  personnel,  supplies and services
with a corresponding  reduction of costs. If oil and gas prices increase,  there
could be a return to shortages  and  corresponding  increases in the cost to the
Company of exploration, drilling and production of oil and gas.

Financial Instrument Market Risk

         Directly, and through its 74% investment in Panterra, the Company holds
derivative  contracts  and  financial  instruments  that  have cash flow and net
income exposure to changes in commodity prices or interest rates.  Financial and
commodity-based  derivative  contracts  are used to limit the risks  inherent in
some crude oil and natural gas price changes that have an effect on the Company.
In prior years the Company has occasionally hedged interest rates, and may do so
in the future should circumstances warrant.

         The Company's Board of Directors has adopted a policy regarding the use
of derivative  instruments.  This policy  requires every  derivative used by the
Company to relate to underlying offsetting positions,  anticipated  transactions
or firm  commitments.  It prohibits the use of  speculative,  highly  complex or
leveraged  derivatives.  Under the policy,  the Chief Executive Officer and Vice
President of Finance must review and approve all risk  management  programs that
use  derivatives.  The Audit  Committee of the Company's Board of Directors also
periodically reviews these programs.

                                      -42-
<PAGE>

         Commodity Price Risk. The Company uses various hedging  arrangements to
manage the  Company's  exposure to price risk from its natural gas and crude oil
production.  These  hedging  arrangements  have the  effect  of  locking  in for
specified periods,  at predetermined  prices or ranges of prices, the prices the
Company will receive for the volumes to which the hedge  relates.  Consequently,
while these hedging arrangements are structured to reduce the Company's exposure
to decreases in prices associated with the hedged commodity, they also limit the
benefit the Company might otherwise receive from any price increases  associated
with the hedged  commodity.  A  hypothetical  10% change in the year-end  market
prices of  commodity-based  swaps and futures  contracts on a notional amount of
11,250  MMBtu  would have  caused a potential  $1.9  million  change in net loss
before income taxes for the Company for contracts in place on December 31, 1998.
Results of operations for Panterra (a non-taxable  entity) would have changed by
$48,000 on a notional  amount of 39 MBbls.  These changes were not discounted to
present  value since the latest  expected  maturity date of all of the swaps and
futures  contracts is less than one year from the reporting date. The derivative
gain or loss  effectively  offsets the loss or gain on the underlying  commodity
exposures  that have been  hedged.  The fair  values of the swaps are  estimated
based on quoted market prices of comparable  contracts and  approximate  the net
gains or losses that would have been  realized if the  contracts had been closed
out at year end.  The fair  values  of the  futures  are based on quoted  market
prices obtained from the New York Mercantile Exchange.

         Interest Rate Risk. Market risk is estimated as the potential change in
fair  value  resulting  from an  immediate  hypothetical  one  percentage  point
parallel  shift in the  yield  curve.  The  sensitivity  analysis  presents  the
hypothetical  change in fair value of those  financial  instruments  held by the
Company at December 31, 1998,  which are sensitive to changes in interest rates.
For fixed-rate  debt,  interest rate changes affect the fair market value but do
not impact  results of  operations or cash flows.  Conversely  for floating rate
debt, interest rate changes generally do not affect the fair market value but do
impact future results of operations  and cash flows,  assuming other factors are
held  constant.  The  carrying  amount  of  the  Company's  floating  rate  debt
approximates its fair value. At December 31, 1998, the Company had floating rate
debt of $19.4 million and had no fixed rate debt. Assuming constant debt levels,
the results of operations and cash flows impact for the next year resulting from
a one percentage point change in interest rates would be approximately  $190,000
before taxes.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS






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

We have audited the accompanying  consolidated balance sheets of St. Mary Land &
Exploration Company (a Delaware corporation) and subsidiaries as of December 31,
1998  and  1997,  and  the  related   consolidated   statements  of  operations,
stockholders'  equity,  and cash  flows for each of the two years in the  period
ended December 31, 1998. 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 audits.

We  conducted  our  audits  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 audits provide 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, 1998 and 1997, and the
consolidated  results of its  operations  and its cash flows for each of the two
years in the  period  ended  December  31,  1998 in  conformity  with  generally
accepted accounting principles.

              ST. MARY LAND & EXPLORATION COMPANY AND SUBSIDIARIES
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                DECEMBER 31, 1998


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 natural gas and crude oil. In December  1998 the Company sold its
remaining  interests in properties located in Canada.  The Company's  operations
are  conducted  entirely  in the United  States.  In  February  1997 the Company
completed the sale of its interest in the Russian joint venture.

Basis of Presentation:

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

         The Company  accounts for its investment in Summo Minerals  Corporation
("Summo") under the equity method of accounting.  The Company  accounted for its
investment in The Limited Liability Company  Chernogorskoye  (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 74% 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 from joint interest
owners. 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.

         The Company has accounts  with separate  banks in Denver,  Colorado and
Shreveport, Louisiana. At December 31, 1998 and 1997, the Company had $4,697,000
and  $7,295,000,  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.

                                      F-8

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.

         The Company reviews its long-lived  assets for impairments  when events
or changes in circumstances  indicate that an impairment may have occurred.  The
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.
During 1998, 1997 and 1996 the Company  recorded  impairment  charges for proved
properties of $17,483,000, $5,202,000 and $408,000, respectively.

         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.

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 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.
Related  receivables  totaling $1,928,000 at December 31, 1998 and $1,955,000 at
December  31, 1997 are  included  in other  assets in the  accompanying  balance
sheets. The Company also reduces revenue for gas sold by the Company that cannot
be  balanced  in the  future due to  insufficient  remaining  reserves.  Related
payables  totaling  $872,000 at December 31, 1998 and $1,105,000 at December 31,
1997 are included in other liabilities 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).

                                      F-9

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 a net gain of $1,873,000 on these
contracts  for the year  ended  December  31,  1998 and  realized  net losses of
$3,242,000  and  $4,253,000 on these  contracts for the years ended December 31,
1997 and 1996, 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.

         In June 1998, the Financial  Accounting Standards Board ("FASB") issued
Statement of Financial  Accounting  Standards ("SFAS") No. 133,  "Accounting for
Derivative  Instruments  and  Hedging  Activities,"  effective  for  all  fiscal
quarters of fiscal years beginning  after June 15, 1999. The Statement  requires
companies  to  report  all  derivatives  at  fair  value  as  either  assets  or
liabilities and bases the accounting treatment of the derivatives on the reasons
an entity holds the instrument.  The Company is currently  reviewing the effects
this  Statement  will  have  on the  financial  statements  in  relation  to the
Company's hedging activities.

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.

Earnings Per Share:

         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. 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. As of December 31, 1998,  there
were 66,748 securities that would normally be considered  dilutive.  However, as
the Company was in a net loss position for the year ended December 31, 1998, all
of the  outstanding  options were  considered  anti-dilutive  and were therefore
excluded  from the  diluted  earnings  per share  calculation.  The  outstanding
dilutive  securities for the years ended December 31, 1997 and 1996 were 132,666
and 66,326,  respectively.  All net income of the Company is available to common
stockholders.

Stock-Based Compensation:

         The Company accounts for stock-based  compensation  using the intrinsic
value  method  prescribed  in  Accounting   Principles  Board  Opinion  No.  25,
"Accounting for Stock Issued to Employees" ("APB No. 25").  Compensation expense
for stock options,  if any, is measured as the excess of the quoted market price
of the Company's stock at the date of grant over the amount an employee must pay
to acquire the stock.

         SFAS No. 123,  "Accounting for Stock-Based  Compensation,"  established
accounting  and  disclosure  requirements  using a  fair-value-based  method  of
accounting for stock-based employee  compensation plans. The Company has elected
to remain on its  current  method of  accounting  as  described  above,  and has
adopted the disclosure requirements of SFAS No. 123.

Comprehensive Income:

         In 1998 the  Company  adopted  SFAS No. 130,  "Reporting  Comprehensive
Income." This  statement  establishes  rules for the reporting of  comprehensive
income  and its  components.  Comprehensive  income  consists  of net income and
unrealized gains and losses on marketable equity securities held for sale and is
presented in the consolidated  statements of stockholders'  equity. The adoption
of SFAS  No.  130 had no  impact  on  total  stockholders'  equity.  Prior  year
financial  statements have been  reclassified to conform to the  requirements of
SFAS No. 130.

Major Customers:

         During 1998 no  individual  customer  accounted  for 10% or more of the
Company's  total  oil and gas  production  revenue.  During  1997 two  customers
individually  accounted for 10.6% and 10.2% of the  Company's  total oil and gas
production revenue.

Industry Segment and Geographic Information:

         The Company operates  predominantly in one industry  segment,  which is
the  exploration,  development  and production of natural gas and crude oil, and
all of the Company's operations are conducted in the United States.Consequently,
the Company currently reports as a single industry segment.

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.

Reclassifications:

         Certain amounts in the 1997 and 1996 consolidated  financial statements
have been reclassified to correspond to the 1998 presentation.

3.    Summo Minerals Corporation Investment and Receivable:

         As of December 31, 1998 and 1997,  the Company owned  9,924,093  shares
(37% of total shares  outstanding)  of Summo, a North American  mining  company,
with a total cost of  $5,859,000.  The Company also owned warrants to acquire an
additional  616,090  shares of Summo  common  stock as of December  31, 1998 and
1997.  These  warrants  expired  January  12,  1999.  The  market  value of this
investment  declined  to  $705,000 at  December  31,  1998.  For the years ended
December  31,  1998,  1997 and 1996 the Company  reported  equity in losses from
Summo of $661,000, $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 ("LVMC"), 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 LVMC. The agreement is subject to certain conditions,  including
finalization  of the  necessary  project  financing.  In September  1998,  Summo
received final regulatory approval to develop the Project.

         The Company has agreed to provide Summo with interim financing of up to
$3,471,000  for the  Project  in the  form of a loan  due in June  1999  bearing
interest at the prime rate plus 1%. As security for this loan, Summo has pledged
its  interest  in LVMC to the  Company  by  entering  into a pledge and security
agreement,  a deed of trust, and an assignment of rents and security  agreement.
All of these agreements are dated November 23, 1998. As of December 31, 1998 and
1997, the amounts  outstanding  under this loan were  $2,869,000 and $2,081,000,
respectively.  Additional  amounts totaling $188,000 have been advanced to Summo
under this loan to date in 1999.

                                      F-12
<PAGE>


         The principal  amount of the note  outstanding  at December 31, 1998 is
convertible into shares of Summo common stock at a conversion price equal to the
weighted-average trading price of the common stock on the Toronto Stock Exchange
for the twenty  trading days  immediately  prior to and  including  December 31,
1998. The principal  amount of advances made by the Company to Summo during 1999
are convertible into shares of Summo common stock at a conversion price equal to
the  weighted-average  trading  price of the common  stock on the Toronto  Stock
Exchange for the twenty trading days immediately prior to and including June 12,
2000.  Upon   capitalization  of  LVMC  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.

         Future  development  and  financial  success of the Project are largely
dependent on the market price of copper,  which is  determined  in world markets
and is subject to significant fluctuations.  Current copper prices have declined
to ten-year lows and do not justify  construction and development of the Project
at this time.  Management  believes that copper prices will recover and that the
Project will have  considerable  value at that time. The Company has the ability
to fund the carrying costs of the property and the intent to retain its interest
in the Project until copper prices do recover.

         The Company has analyzed its net  investment in Summo and the effect of
persistent  depressed  copper prices and increased  worldwide  copper  inventory
levels on Summo's stock price.  Management  believes Summo's stock price decline
is not temporary and that its value is impaired. Consequently, the Company wrote
down its net investment in Summo to net  realizable  value in the fourth quarter
of 1998. Management believes the recorded net investment is recoverable.

4.    Income Taxes:

         The provision for income taxes consists of the following:

         At  December  31,  1998,  the  Company  had  state net  operating  loss
carryforwards  of approximately  $25,800,000  which expire between 1999 and 2012
and  alternative  minimum tax credit  carryforwards  of $1,123,000  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 1998 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 and  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 items:

5.    Long-term Debt and Notes Payable:

         On June 30, 1998,  the Company  entered into a new long-term  revolving
credit  agreement that replaced the agreement dated March 1, 1993 and amended in
April  1996.  The new  credit  agreement  specifies  a  maximum  loan  amount of
$200,000,000,  and the initial aggregate  borrowing base was  $115,000,000.  The
lender may periodically  re-determine the aggregate  borrowing base. In December
1998 the borrowing base was reduced by the lender to $105,000,000 as a result of
the sale of certain  producing  properties in Oklahoma.  The accepted  borrowing
base was  $40,000,000 at December 31, 1998. The credit  agreement has a maturity
date of December  31,  2005,  and  includes a revolving  period that  matures on
December  31,  2000.  The Company  can elect to allocate up to 50% of  available
borrowings to a short-term tranche due in 364 days. The Company must comply with
certain covenants including  maintenance of stockholders'  equity at a specified
level and  limitations on additional  indebtedness.  As of December 31, 1998 and
1997,  $10,500,000 and  $14,450,000,  respectively,  was outstanding  under this
credit agreement.

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

INTEREST RATES:

  but less than 0.5 to 1.0                (b) the higher of the Federal Funds
                                              Rate + 0.5% or the Prime Rate

Greater than or equal                   The  Company's  option of 
  to 0.5 to 1.0                           (a)  LIBOR + 1.25% or 
                                          (b) the  higher of the Federal Funds
                                              Rate + 0.625% or
                                              the Prime Rate + 0.125%

COMMITMENT FEES:

Debt to Capitalization Ratio            Short-Term Tranche    Long-Term Tranche
- ----------------------------            ------------------    -----------------
Less than 0.5 to 1.0                         0.125%                0.25%
Greater than or equal to 0.5 to 1.0          0.375%                0.50%

         At December 31, 1998, the Company's  debt to  capitalization  ratio as
defined under the credit  agreement was 0.13 to 1.0.

         Panterra,  in which the Company has a 74% general partnership ownership
interest, has a separate credit facility with a $21,000,000 borrowing base as of
December 31, 1998, and $12,000,000  and  $11,000,000  outstanding as of December
31, 1998 and 1997, respectively. In June 1997, Panterra entered into this credit
agreement replacing a previous agreement,  which was due March 31, 1999. The new
credit  agreement   includes  a  revolving  period  converting  to  a  five-year
amortizing loan on June 30, 2000.  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 0.75% 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 1.25%
when the Partnership's  debt to partners' capital ratio is greater than 100%. At
December 31, 1998,  Panterra's  debt to partners'  capital  ratio as defined was
66%.

         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  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
$484,000,  $447,000  and  $426,000  in 1998,  1997 and 1996,  respectively.  The
Company also leases various office equipment under operating leases.  The annual
minimum lease payments for the next five years are presented below:

         On January 29, 1999, the Company  obtained a commitment for a letter of
credit ("LOC") from an U.S. bank. The beneficiary of the LOC is a Canadian bank,
and the LOC is used as collateral for an irrevocable letter of guarantee ("ILG")
which was  furnished  to the  Canadian  federal  taxing  authority.  The ILG was
provided  on  behalf of the  Company  and its joint  venture  partners  securing
possible  Canadian federal tax liabilities  resulting from the sale of assets in
Canada.

         The  Company  had the  following  commodity  contracts  in  place as of
December 31, 1998, to hedge or otherwise  reduce the impact of oil and gas price
fluctuations:

         (a) Price collar  contract.  Price  ceiling  shown,  price floor equals

         The fair value of the Company's  commodity  hedging  contracts based on
year-end futures pricing would have caused the Company to receive  approximately
$776,000 if these contracts had been terminated on December 31, 1998.

         At  December  31,  1998,  Panterra,  in which  the  Company  owns a 74%
interest,  held various hedge contracts covering 39,000 Bbls of future crude oil
production.  These contracts expire at various dates through May 1999.  Panterra
will receive  fixed  prices  ranging from 15.68 per Bbl to 16.80 per Bbl. If the
open hedging contracts had been liquidated at December 31, 1998,  Panterra would
have recognized a gain of approximately $152,000.

         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 attempts to limit 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.  Including  hedges entered
into since December 31, 1998, and those detailed  above,  the Company has hedged
approximately 45% of its estimated 1999 gas production at an average fixed price
of $2.10 per MMBtu,  approximately 9% of its estimated 1999 oil production at an
average fixed price of $15.11 per Bbl and approximately 8% of its estimated 2000
oil production at an average fixed price of $14.76 per Bbl. The Company has also
purchased  options  resulting  in  price  collars  on  approximately  7% of  the
Company's  estimated 1999 gas production  with price ceilings  between $2.00 and
$2.63 per MMBtu and price floors between $1.50 and $1.90 per MMBtu.

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 $229,000 in 1998 and $416,000 in 1997 relating
to net profits attributable to these properties.

                                      F-17
<PAGE>

         Through  September  1992 the Company had a restricted  stock bonus plan
("Plan")  covering  officers and key employees.  Participants have the option at
any time to sell  shares  acquired  under the Plan to the  Company at their fair
market  values.  At  December  31,  1998,  there were 28,455  shares  issued and
outstanding under the Plan.

         In March 1992 the Company adopted a stock  appreciation  rights ("SAR")
plan for officers and directors. 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  was  reduced  by  $197,000  in 1998  under  the SAR plan.
Compensation  expense  recognized under the SAR plan was $161,000 and $1,567,000
in 1997 and 1996,  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 and to the  fluctuation  of the stock  price  below the  capped  price of
$20.50.

         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 $269,000,  $231,000 and
$199,000 for the years ended December 31, 1998, 1997 and 1996, 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 "Option  Plans").  The Option Plans grant
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 Option Plans. The Company intends to increase the number of shares of common
stock  available  for issuance  under the Option  Plans and to seek  shareholder
approval of such  increase  in 1999.  During  1996  options to purchase  256,598
shares of the  Company's  common stock were granted under the Option Plans at an
exercise  price of $20.50 in connection  with the  termination  of future awards
under the  Company's  SAR plan.  Also during  1996,  options to purchase  42,880
shares were granted  under the Option Plans at an exercise  price  $24.875.  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 Option Plans were exercised during the year ended December 31,
1996. In 1997 14,072 options under the Option Plans 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. During the year ended December 31, 1998, 251,774
options were granted and no options were exercised  under the Option Plans.  All
options  granted to date under the Option  Plans have been  granted at  exercise
prices equal to the  respective  market prices of the Company's  common stock on
the grant dates.

         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, leaving 20,000 options
outstanding.  None of these options were exercised in 1998.

         SFAS  No.  123  establishes  a fair  value  method  of  accounting  for
stock-based  compensation  plans either through  recognition or disclosure.  The
Company has elected to  continue  following  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 1998
was  estimated  using  the  following  weighted-average  assumptions:  risk-free
interest  rate of  4.6%;  dividend  yield of  1.08%;  volatility  factor  of the
expected market price of the Company's common stock of 40.16%; and expected life
of the  options  of 7.5 years.  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 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 expected life of the options of 4.8 years.

         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 85% of the lower 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,  and
8,424 shares were sold under the Stock  Purchase Plan in 1998.  No  compensation
expense was recorded in 1998 related to the plan.

8.    Pension and Other Postretirement Benefits

         The Company's employees participate in a non-contributory  pension plan
covering  substantially all employees who meet age and service requirements (the
qualified  plan). The Company also has a supplemental  non-contributory  pension
plan  covering  certain  management  employees  ( the  nonqualified  plan) and a
postretirement  non-contributory  health care plan.  The  Company's  disclosures
about pension and other postretirement benefits is as follows:

         The Company's  nonqualified pension plan was the only pension plan with
an  accumulated  benefit  obligation  in  excess  of  plan  assets.  The  plan's
accumulated  benefit  obligation was $274,000 at December 31, 1998, and $271,000
at December 31, 1997. There are no plan assets in the  nonqualified  plan due to
the nature of the plan.  The Company's  other plan for  postretirement  benefits
also has no plan  assets.  The  aggregate  benefit  obligation  for that plan is
$121,000 as of December 31, 1998, and $88,000 as of December 31, 1997.

         Assumptions used in the measurement of the Company's benefit obligation
are as follows:

         Prior  service costs are  amortized on a  straight-line  basis over the
average  remaining  service period of active  participants.  Gains and losses in
excess of 10% of the greater of the benefit  obligation  and the  market-related
value of assets are  amortized  over the  average  remaining  service  period of
active participants.

         The  Company  has  one  nonpension   postretirement   benefit  plan;  a
noncontributory health care plan.

         Assumed  health care cost trend rates have a significant  effect on the

9.       Sale of Oklahoma Properties:

         On  December  15,  1998,  the  Company  closed the sale of a package of
non-strategic  properties  to ONEOK  Resources  Company for a purchase  price of
$22,201,000.   The  Company  received  $22,117,000  in  cash  proceeds,  net  of
transaction   costs  and   customary   closing   adjustments   made  to  reflect
post-effective  date  revenues and expenses.  The  transaction  was  consummated
pursuant to a Purchase and Sale Agreement dated November 12, 1998,  effective as
of September 1, 1998. The assets sold consist of producing oil and gas wells and
undeveloped  leasehold  acreage within eight fields located in Beckham and Roger
Mills counties, Oklahoma.

         The  majority  of the  proceeds  from this  property  sale were used to
reduce the Company's  outstanding bank debt in anticipation of re-deploying this
capital in the Company's drilling, exploration and acquisition programs in 1999.

10.    Investment in Russian Joint Venture:

         In September  1991 the Company,  through an  affiliate,  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.  In accordance
with  the  terms  of  the  Acquisition  Agreement,  the  Company  received  cash
consideration of $5,608,000 before  transaction  costs, KMOC common stock valued
at $1,869,000,  and a receivable in a form  equivalent to a retained  production
payment of  approximately  $10,134,000  plus  interest at 10% per annum from the
limited liability company formed to hold the Russian joint venture interest. The
Company's  receivable is  collateralized  by the partnership  interest sold. The
Company  has the  right,  subject  to certain  conditions,  to  require  KMOC to
purchase the  Company's  receivable  from the net proceeds of an initial  public
offering of KMOC common stock.  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 or on or after March 10, 2000,
whichever  occurs first.  The  transaction  closed on February 12, 1997, and the
Company  recorded  a gain on the sale of  $9,671,000.  The  Company's  equity in
income for the  Russian  joint  venture  for 1997  through  the date of sale was
$203,000.  Uncertain  economic  conditions  in Russia and lower oil prices  have
affected the  realizability  of the  convertible  receivable.  As a result,  the
Company  has  reduced  the  carrying  amount of the  receivable  to its  minimum
conversion  value,  incurring a charge to operations of $4,553,000  for the year
ended December 31, 1998.

         Summarized  financial  information of the Russian joint venture for the
last full year owned by the Company is shown below:

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  consolidated
statements of income. The Company's remaining real estate assets consist of land
held for sale with a carrying cost of $1,095,000  and  $1,149,000 as of December
31, 1998 and 1997, respectively, which in the opinion of management is less than
the estimated net realizable values.

Oil and Gas Reserve Quantities (Unaudited):

         The reserve  information as of December 31, 1998,  1997,  1996 and 1995
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.

         Presented  below is a summary  of the  changes  in  estimated  domestic
reserves of the Company and its share of the Russian joint venture reserves:

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

     SFAS  No.  69,  "Disclosures  About  Oil  and  Gas  Producing  Activities,"
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 benchmark prices and costs, including  transportation and
basis differential, in effect at year-end to the estimated quantities of oil and
gas to be produced in the future.  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 FASB 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.

         The following  summary sets forth the  Company's  future net cash flows
relating  to  proved  oil and gas  reserves  based on the  standardized  measure
prescribed in SFAS No. 69:

$26,000,000,  unless  Borrower  and the Bank  hereafter  mutually  agree  upon a
different  amount  or unless  the  Borrowing  Base is  redetermined  or  reduced
pursuant to Section 3.03 below prior to such date.

                "Borrowing  Base Period" means:  (a) the period from the date of
this Agreement through December 31, 1997; (b) thereafter,  each six-month period

Conversion Date, minus the aggregate amount of all principal  payments  required
to be made on the Loan  pursuant  to the terms of Sections  2.04(a)  and/or 3.02
below prior to the date as of which the determination of the "Commitment Amount"
is being made.

Borrower  may make no such  election  during the  continuance  of a Default  and
Borrower  may make such an election  with respect to an already  existing  Fixed
Rate Portion only if such election will take effect at or after the  termination
of the Interest Period  applicable to such already  existing Fixed Rate Portion.
Each election by Borrower of a Fixed Rate Portion shall:

                (a) Be made in  writing in the form and  substance  of the "Rate
        Election" attached hereto as Exhibit E, duly completed;

                (b) Specify the amount of the outstanding  principal  balance of
        all  Advances  which  Borrower  desires  to  designate  as a Fixed  Rate
        Portion, the first day of the Interest Period which is to apply thereto,
        and the length of such Interest Period; and

                (c) Be received  by the Bank not later than 10:00 a.m.,  Denver,
        Colorado time, on the second Business Day preceding the first day of the
        specified Interest Period.

Each election which meets the requirements of this Section 2.09 (herein called a
"Rate Election") shall be irrevocable.  Borrower may make no Rate Election which
does not specify an Interest  Period  complying with the definition of "Interest
Period" in Section 1.01, and the amount of the Fixed Rate Portion elected in any
Rate Election must be an integral multiple of $100,000.  Upon the termination of
each  Interest  Period,  the portion of the Loan  theretofore  constituting  the
related Fixed Rate Portion shall, unless the subject of a new Rate Election then
taking effect,  automatically  become a part of the Base Rate Portion and become
subject to all provisions of the Loan Documents governing the Base Rate Portion.
Borrower shall have no more than five Fixed Rate Portions in effect at any time.

                Section  2.10.  Increased  Cost of Fixed Rate  Portions.  If any
applicable  domestic or foreign law, treaty,  rule or regulation (whether now in
effect or  hereafter  enacted or  promulgated,  including  Regulation  D) or any
interpretation or administration  thereof by any governmental  authority charged
with the  interpretation  or  administration  thereof (whether or not having the
force of law):

                        (a) Shall  change  the  basis of  taxation  of  payments
to the Bank of any principal,  interest,  or other amounts  attributable  to any
Fixed Rate Portion or otherwise due under this Agreement in respect of any Fixed
Rate Portion  (other than taxes imposed on the overall net income of the Bank or
any lending office of the Bank by any jurisdiction in which the Bank or any such
lending office is located); or

                         (b)  Shall  change,   impose,  modify,  apply  or  deem
applicable any reserve,  special  deposit or similar  requirements in respect of
any Fixed Rate Portion  (excluding those for which the Bank is fully compensated
pursuant to adjustments  made in the definition of Fixed Rate) or against assets
of,  deposits with or for the account of, or credit extended by, the Bank to the
extent the same relate to a Fixed Rate Portion; or

                         (c)  Shall   impose  on  the  Bank  or  the   interbank
eurocurrency  deposit  market  any other  condition  affecting  any  Fixed  Rate
Portion,  the result of which is to increase  the cost to the Bank of funding or
maintaining any Fixed Rate Portion or to reduce the amount of any sum receivable
by the Bank in respect of any Fixed Rate Portion by an amount deemed by the Bank
to be material;

then: (x) the Bank shall promptly notify Borrower in writing of the happening of
such  event,  (y)  Borrower  shall upon  demand pay to the Bank such  additional
amount  or  amounts  as will  compensate  the  Bank for any  such  event  (on an
after-tax  basis),  and (z) Borrower  may elect,  by giving to the Bank not less
than three Business Days' notice,  to convert all (but not less than all) of any
such Fixed Rate Portion into a part of the Base Rate Portion.

                         Section 2.11  Availability. If the Bank shall determine
(which determination  shall, upon notice thereof to Borrower,  be conclusive and
binding on Borrower and the Bank) that: (a) the introduction of or any change in
or in the  interpretation  of any  law,  treaty,  rule or  regulation  makes  it
unlawful or impracticable,  or any central bank or other governmental  authority
asserts  that it is  unlawful,  for the Bank to make,  continue or maintain  any
Fixed Rate Portion or shall  materially  restrict  the  authority of the Bank to
purchase or take  offshore  deposits of dollars  (i.e.,  "eurodollars"),  or (b)
matching deposits appropriate to fund or maintain any Fixed Rate Portion are not
available to it, or (c) the formula for calculating the Eurodollar Rate does not
fairly reflect the cost to the Bank of making or maintaining loans based on such
rate, then  Borrower's  right to elect Fixed Rate Portions shall be suspended to
the  extent  and  for  the  duration  of such  illegality,  impracticability  or
restriction  and all Fixed Rate  Portions (or portions  thereof)  which are then
outstanding  or are then the  subject  of any Rate  Election  and  which  cannot
lawfully or  practicably  be  maintained or funded shall  immediately  become or
remain part of the Base Rate Portion.  Borrower agrees to indemnify the Bank and
hold it harmless against all costs, expenses, claims, penalties, liabilities and
damages which may result from any such change in law, treaty, rule,  regulation,
interpretation or administration.

         Section 2.12.  Reimbursable Taxes.  Borrower covenants and agrees that:

                    (a)  Borrower will indemnify the Bank against, and reimburse
the Bank for, all present and future income,  excise,  stamp or franchise  taxes
and other  taxes,  fees,  duties,  withholdings  or other  charges of any nature
whatsoever  imposed,  assessed,  levied or  collected  on or in  respect of this
Agreement  insofar  as it  pertains  to a Fixed  Rate  Portion or any Fixed Rate
Portions (whether or not legally imposed,  assessed,  levied or collected),  but
excluding  taxes  imposed on or  measured  by the Bank's net income or  receipts
(such   non-excluded   items   being   called   "Reimbursable    Taxes").   Such
indemnification  shall be on an after-tax basis,  taking into account any income
taxes imposed on the amounts paid as indemnity.

                         (b) All  payments by  Borrower on account of  principal
of, and interest on, the Loan and all other  amounts  payable by Borrower to the
Bank hereunder shall be made in full without  set-off or counterclaim  and shall
be  made  free  and  clear  of and  without  deduction  or  withholding  for any
Reimbursable  Taxes,  all of which shall be for the account of Borrower.  In the
event that any  withholding or deduction from any payment to be made by Borrower
hereunder  is  required  in respect of any  Reimbursable  Taxes  pursuant to any
applicable  law, rule or regulation,  Borrower shall pay on the due date of such
payment, by way of additional interest, such additional amounts as are needed to
ensure that the amount actually  received by the Bank will equal the full amount
the Bank would have received had no such withholding or deduction been required.
If Borrower shall make any deduction or withholding as aforesaid, Borrower shall
within 60 days  thereafter  forward  to the Bank an  official  receipt  or other
official document evidencing payment of such deduction or withholding.

                         (c)  If   Borrower   is  ever   required   to  pay  any
Reimbursable Tax with respect to any Fixed Rate Portion,  Borrower may elect, by
giving to the Bank not less than three  Business  Days'  notice,  to convert all
(but not less than all) of any such Fixed Rate  Portion  into a part of the Base
Rate Portion, but such election shall not diminish Borrower's  obligation to pay
all Reimbursable Taxes.

                Section  2.13.   Funding  Losses.   In  addition  to  its  other
obligations  hereunder,  Borrower will indemnify the Bank against, and reimburse
the Bank on demand  for,  any loss or  expense  (including  any loss or  expense
incurred by reason of the liquidation or reemployment of deposits or other funds
acquired by the Bank to make, continue or maintain any Fixed Rate Portion or any
Advance) as a result of: (a) any payment or  prepayment  (whether  authorized or
required  hereunder or  otherwise) of all or any portion of a Fixed Rate Portion
on a date other than the scheduled  last day of the Interest  Period  applicable
thereto; (b) any payment or prepayment, whether required hereunder or otherwise,
of the Loan made after the delivery,  but before the  effective  date, of a Rate
Election,  if such  payment  or  prepayment  prevents  such Rate  Election  from
becoming  fully  effective;  (c) the failure of any Advance to be made or of any
Rate  Election to become  effective  due to any  condition  precedent  not being
satisfied or due to any other action or inaction of any Obligated Person; or (d)
any conversion (whether authorized or required hereunder or otherwise) of all or
any  portion  of any Fixed  Rate  Portion  into the Base Rate  Portion or into a
different Fixed Rate Portion on a day other than the day on which the applicable
Interest Period ends.

                Section  2.14.   Capital   Reimbursement.   If  either  (a)  the
introduction or  implementation of or the compliance with or any change in or in
the  interpretation  of any law, rule or regulation,  or (b) the introduction or
implementation  of or the  compliance  with any request,  directive or guideline
from any central bank or other governmental authority (whether or not having the
force of law) affects or would affect the amount of capital required or expected
to be maintained by the Bank or any corporation controlling the Bank, then, upon
demand  by the  Bank,  Borrower  will  pay to the  Bank,  from  time  to time as
specified by the Bank,  such  additional  amount or amounts which the Bank shall
determine  to  be  appropriate  to  compensate  the  Bank  or  any   corporation
controlling the Bank in light of such circumstances, to the extent that the Bank
reasonably  determines that the amount of any such capital would be increased or
the rate of return on any such  capital  would be  reduced  by or in whole or in
part based upon the existence of the Loan or the Bank's  commitments  under this
Agreement or the existence of the Letters of Credit issued hereunder.


                                   ARTICLE III

                           OFFSET; INCREASED PAYMENTS

                Section 3.01. Bank Accounts and Offset.  To secure the repayment
of the Loan, Borrower hereby grants to the Bank a security interest, a lien, and
a right of  offset,  each of which  shall be upon and  against:  (a) any and all
moneys,  securities or other  property (and the proceeds  therefrom) of Borrower
now or  hereafter  held or received by or in transit to the Bank from or for the
account of Borrower,  whether for safekeeping,  custody,  pledge,  transmission,
collection or otherwise,  (b) any and all deposits (general or special,  time or
demand,  provisional  or final)  of  Borrower  with the Bank,  and (c) any other
credits and claims of Borrower at any time existing against the Bank,  including
without  limitation  claims under  certificates  of deposit;  provided  that the
foregoing  shall not apply to amounts  which  Borrower is holding as trustee for
the benefit of any third party. Upon the occurrence of any Event of Default, the
Bank is hereby authorized to foreclose upon, offset, appropriate,  and apply, at
any time and from time to time,  without  notice to Borrower,  any and all items
hereinabove  referred to against  the Loan  (whether or not the Loan is then due
and payable).

                Section  3.02.  Increased  Payments.   At  any  time  after  the
occurrence  of an Event of Default,  the Bank shall have the right,  in its sole
discretion,  upon  written  notice to Borrower,  to require that future  monthly
payments of principal and interest made by Borrower  pursuant to this  Agreement
be in an amount  equal to the  greatest  of: (a) the amount set forth in Section
2.04,  (b) up to 70 percent of Gross  Revenues for the calendar month two months
prior to the  calendar  month in which  such  payment  is due,  or (c) up to 100
percent of Net Revenues for the calendar  month two months prior to the calendar
month in which such payment is due;  provided that any such payments shall be in
addition to any amounts payable pursuant to Section 3.03 below.

                Section   3.03.    Periodic    Reviews   and   Borrowing    Base
Determinations.  As  of  approximately  January  1  and  July  1 of  each  year,
commencing  January 1, 1998,  through the Maturity Date, and at such other times
as the Bank may  determine,  the Bank  will  perform a review of the Oil and Gas
Properties  and will  determine  the  Borrowing  Base,  taking into account such
factors as the Bank in its reasonable  discretion  deems  appropriate.  The Bank
will give notice to Borrower (as of approximately 10 days prior to the effective
date of any new  determination  of the Borrowing Base pursuant  hereto),  of the
amount of the new Borrowing  Base;  provided that Borrower shall have the right,
by giving notice to the Bank,  to make an election to reduce the Borrowing  Base
to an amount less than the amount so  determined by the Bank;  provided  further
that,  as to any  Borrowing  Base  Period for which  Borrower  has so elected to
reduce the Borrowing Base, not more than once during such Borrowing Base Period,
Borrower  shall  have the  right,  by giving  notice  to the  Bank,  to elect to
increase the  Borrowing  Base to an amount not greater than the  Borrowing  Base
originally  determined by the Bank for such Borrowing Base Period, so long as no
Default has occurred and is continuing at the time of such election and Borrower
pays to the Bank at that  time  the  additional  amount  of the  commitment  fee
payable  pursuant to Section  2.08(a) above as if the increased  Borrowing  Base
elected by Borrower had been in effect at all times from and after the first day
of such Borrowing Base Period.

                      If, at the time of any determination of the Borrowing Base
or at any other time,  the  then-outstanding  principal  balance of all Advances
plus the face amount of all Letters of Credit outstanding  hereunder exceeds the
Commitment Amount, Borrower shall, within 30 days of any such determination: (a)
mortgage,  by  instruments  satisfactory  in form  and  substance  to the  Bank,
sufficient  additional  available  assets or  properties  owned by Borrower  and
satisfactory  to the Bank to induce the Bank to make a  re-determination  of the
Borrowing Base which causes the  Commitment  Amount to be increased by an amount
sufficient to eliminate  such excess;  or (b) prepay the  outstanding  principal
balance of the Loan in an amount at least equal to the amount of such excess; or
(c) commence (and  thereafter  continue) an  amortization  schedule  under which
Borrower  repays the Loan in an amount at least equal to the excess in six equal
monthly principal  installments on the last Business Day of each calendar month,
which  amounts  shall be in addition to the monthly  interest  payments  and any
other  principal  payments  otherwise  due,  such that the entire excess is paid
within six months; or (d) if the Conversion Date has not yet occurred,  elect to
have the Conversion Date occur  immediately.  Failure by Borrower to comply with
the foregoing shall be deemed an Event of Default hereunder.


                                   ARTICLE IV

                              CONDITIONS OF LENDING

liens,  encumbrances and defects,  except for liens and encumbrances in favor of
the Bank; and

                         (f) Any other documents and instruments  which the Bank
shall have reasonably requested including,  without limitation:  partnership and

authorizations,  consents,  approvals, licenses and exemptions; and certificates
of public officials and of officers and representatives of the Obligated Persons
and other persons as to: (1) the accuracy and validity of or compliance with all

other matters pertaining hereto.

                Section 4.02.  Additional  Conditions Precedent to the Advances.

subsequent Advances and to issue any and all Letters of Credit is subject to the
satisfaction of the following conditions precedent:

                         (a)     Any and all representations and warranties made
by Borrower in this  Agreement  or in any of the other Loan  Documents  shall be

and warranties had been made on such date;

                         (b)  There shall not exist on the date of the requested
Advance  or the date of  issuance  of the  Letter of Credit any Event of Default
under this Agreement or any event or condition  that, with the giving of notice,
the lapse of time, or both,  would be an Event of Default under this  Agreement;
and

                         (c)     Borrower shall have performed and complied with
all agreements and conditions  herein  required to be performed or complied with
on or prior to the date of the requested  Advance or the date of issuance of the
requested Letter of Credit.


                                    ARTICLE V

         SECURITY  Section  5.01.  Security.  Payment of the Note  and all other
obligations  of  Borrower  hereunder  shall be secured by liens on and  security
interests in the Collateral, as created pursuant to the Collateral Documents. To
the extent the Collateral  Documents have not heretofore been recorded or filed,
the Bank will record or file (or cause to be  recorded or filed) the  Collateral
Documents at Borrower's  expense promptly after execution and delivery  thereof.
Borrower agrees that, at any time, at the Bank's request, Borrower will promptly
execute  and  deliver  any  mortgages,  deeds of trust,  assignments,  financing
statements  or any other  documents  as may be  necessary  to create and perfect
enforceable  liens or security  interests  in favor of the Bank on any or all of
the Oil or Gas  Properties  owned by Borrower as to which the Bank requests that
such liens and security interests be created and perfected.

                Section 5.02.  Perfection and  Protection of Security  Interests
and Liens. Borrower will cause to be delivered to the Bank from time to time any
financing statements,  continuation  statements,  extension agreements and other
documents,  properly  completed and executed (and acknowledged when required) by
Borrower,  in form and  substance  satisfactory  to the Bank for the  purpose of
creating,  perfecting  or  protecting  liens,  pledges,  security  interests and
assignments  in favor  of the  Bank in and to any of the Oil and Gas  Properties
identified by the Bank.

                Section 5.03.  Security  Opinions.  From time to time during the
term hereof, Borrower will deliver such opinions regarding the Collateral,  from
counsel and in form and content reasonably satisfactory to the Bank, as the Bank
may reasonably  request,  including without limitation  opinions confirming that
the nature  and  extent of  Borrower's  title to the  Collateral  covered by the
Collateral  Documents  as  provided in Section  5.01  (expressly  including  the
Borrower's working and net revenue interests therein) conform to the assumptions
used by the  Bank  in  evaluating  the  Collateral  and  that,  pursuant  to the
Collateral Documents, first enforceable liens thereon have been duly created and
perfected in favor of the Bank.


                                   ARTICLE VI

                         REPRESENTATIONS AND WARRANTIES
                Section 6.01.  Representations  and  Warranties of Borrower.  To
induce  the Bank to enter  into this  Agreement  and to make the Loan,  Borrower
represents and warrants to the Bank (which  representations and warranties shall
survive  the  delivery  of  the  Note  and  shall  be  deemed  to be  continuing
representations  and  warranties  until  repayment  in  full  of  the  Note  and
termination of this Agreement) that:

                         (a)      Existence;  Standing.  Borrower is  a  general
partnership duly organized, validly existing and in good standing under the laws
of the State of Montana.

                         (b)      Qualification to  Do Business.  Each Obligated
Person is duly qualified to do business in each  jurisdiction in which a failure
so to qualify would have a material adverse effect on its business.

                         (c)      Due Authorization. The execution, delivery and
performance by Borrower of this Agreement, the Note and the other Loan Documents
to which it is a party are within its powers,  have been duly  authorized by all
necessary action, and do not contravene Borrower's  organizational  documents or
any law or any contractual restriction binding on or affecting Borrower.

                         (d)    Approvals. No authorization or approval or other
action  by,  and no notice to or filing  with,  any  governmental  authority  or
regulatory  body is required for the due execution,  delivery and performance by
any Obligated Person of the Loan Documents to which each is a party.

                         (e)    Binding Obligations.  This Agreement is, and the
Note, the Collateral Documents and all other Loan Documents to which Borrower is
a party,  when  executed and  delivered  hereunder,  will be,  legal,  valid and
binding obligations of Borrower, enforceable against Borrower in accordance with
their respective terms.

                         (f)  Financial Statements.The balance sheet of Borrower
as of March 31, 1997, and the related  statements of income,  retained  earnings
and cash flows of Borrower  for the fiscal  period  then ended,  copies of which
have been  furnished  to the Bank,  fairly  present the  financial  condition of
Borrower as at such date and the results of the  operations  of Borrower for the
period ended on such date, all in accordance  with GAAP.  Since the date of said
financial statements, there has been no material adverse change in the financial
condition or operations of Borrower  which has not been disclosed to the Bank in
writing.

                         (g)   Use of Proceeds. None of the proceeds of the Loan
will be used to acquire  any  security  in any  transaction  which is subject to
Sections 13 and 14 of the Securities and Exchange Act of 1934.

                         (h)    Regulation U.  No Obligated Person is engaged in
the  business  of  extending  credit for the purpose of  purchasing  or carrying
margin  stock  (within  the  meaning  of  Regulation  U issued  by the  Board of
Governors of the Federal Reserve  System),  and none of the proceeds of the Loan
will be used to purchase or carry any margin stock or to extend credit to others
for the purpose of purchasing or carrying any margin stock.

                         (i)    Other Obligations.  No Obligated Person has with
respect to the Collateral any outstanding indebtedness, obligations, liabilities
(including contingent,  indirect and secondary liabilities and obligations), tax
assessments  against it, or unusual forward or long-term  commitments,  or, with
respect to its other properties which are, in the aggregate,  material  (defined
as being in excess of $10,000) with respect to the  financial  condition of such
Obligated  Person and, in either  case,  not shown in the  financial  statements
referred to in Section 6.01(f) above or in other writings  heretofore  delivered
by Borrower or such Obligated Person to the Bank.

                         (j)      Full Disclosure.  No certificate, statement or
other  information  delivered  herewith or heretofore by any Obligated Person to
the Bank in connection  with the  negotiation of this Agreement or in connection
with any  transaction  contemplated  hereby  contains any untrue  statement of a
material fact or omits to state any material fact known to any Obligated  Person
necessary to make the statements  contained  herein or therein not misleading as
of the date presented.  There is no fact known to any Obligated Person that such
Obligated Person has not disclosed to the Bank in writing which could materially
and adversely affect the properties, business, prospects or condition (financial
or otherwise) of such Obligated Person.

                         (k)      No Litigation.  Except as heretofore disclosed
to the  Bank in  writing,  there  are no  actions,  suits or  legal,  equitable,
arbitrative  or  administrative  proceedings  pending  or, to the  knowledge  of
Borrower,  threatened against any Obligated Person at law or in equity or before
any federal,  state,  municipal or other  governmental  department,  commission,
body, board, bureau, agency, or instrumentality,  domestic or foreign, and there
are no outstanding judgments, injunctions, writs, rulings or orders by any court
or  governmental  body against any  Obligated  Person,  any of their  respective
partners,  shareholders,  directors or officers, which relate to the Collateral,
or, with respect to any Obligated Person  generally,  which do or may materially
and  adversely  (defined  as being in excess of  $10,000)  affect any  Obligated
Person,  their respective  ownership or use of any of their respective assets or
properties,  their respective businesses or financial condition or prospects, or
the right or  ability  of any  Obligated  Person  to enter  into any of the Loan
Documents to which it is a party or to consummate the transactions  contemplated
hereby or to perform  their  respective  obligations  hereunder or in connection
herewith.

                         (l)      No ERISA Liability.  Borrower has no knowledge
of the occurrence of any event with respect to any ERISA Plan which could result
in a  liability  of  any  Obligated  Person  to  the  Pension  Benefit  Guaranty
Corporation,  other than the payment of premiums  (but no late  payment  charge)
pursuant to Section 4007 of ERISA.

substance to the Bank, and so long as the outstanding  principal  balance of all

                Section  9.01.  Amendments,  Etc. No  amendment or waiver of any
provision of the Loan  Documents,  nor consent to any departure by any Obligated
Person  therefrom,  shall in any event be effective  unless the same shall be in

effective only in the specific  instance and for the specific  purpose for which
given.

                Section 9.02. Notices, Etc. All notices and other communications
provided for hereunder shall be in writing in mail, telegraphic communication or
personal delivery,

        if to Borrower at:

or, as to each of the parties,  at such other  address as shall be designated by
such  party in a  written  notice  to the  other  party.  All such  notices  and
communications  shall be  effective  when  received  or  actually  so  delivered
addressed as aforesaid.

                Section 9.03. The Bank's Damage  Limitation.  The Bank shall not
be liable to any Obligated Person for consequential damages, whatever the nature
of a breach by the Bank in its obligations relating to the transactions governed
or contemplated by this Agreement.

                Section 9.04. Arbitration. Subject to the provisions of the next
paragraph  below,  the Bank and Borrower agree to submit to binding  arbitration
any and all claims,  disputes and controversies between or among them (and their
respective employees,  officers, directors, attorneys and other agents) relating
to the Loan and its negotiation, execution,  collateralization,  administration,
repayment, modification, extension or collection. Such arbitration shall proceed
in Denver,  Colorado,  shall be  governed  by Colorado  law  (including  without
limitation  the  provisions  of CRS  13-21-102(5))  and  shall be  conducted  in
accordance  with the Commercial  Arbitration  Rules of the American  Arbitration
Association ("AAA"). Any award entered in an arbitration,  whether on motions or
at a  hearing,  with or without  testimony  from  witnesses,  shall be made by a
written  opinion  stating the reasons  for the award made.  The  decision of any
arbitration  pursuant  to this  Agreement  shall be made based on  Colorado  law
without  reference to any choice of law rules.  Judgment on any award  hereunder
may be entered in any court having jurisdiction.

                Nothing in the  preceding  paragraph,  nor the  exercise  of any
right to arbitrate thereunder, shall limit the right of any party hereto: (a) to
foreclose  against any real or personal  property  collateral by the exercise of
the power of sale under a deed of trust,  mortgage,  or other security agreement
or  instrument  or applicable  law; (b) to exercise  self-help  remedies such as
setoff or repossession;  or (c) to obtain provisional or ancillary remedies such
as replevin,  injunctive relief,  attachment or appointment of a receiver from a
court  having  jurisdiction,  before,  during  or  after  the  pendency  of  any
arbitration  proceeding.  The institution and maintenance of any action for such
judicial relief, or pursuit of provisional or ancillary remedies, or exercise of
self-help  remedies  shall not constitute a waiver of the right or obligation of
any party to submit any claim or dispute to arbitration,  including those claims
or  disputes  arising  from  exercise  of any  judicial  relief,  or  pursuit of
provisional or ancillary remedies or exercise of self-help remedies.

                Arbitration  hereunder  shall be before a three-person  panel of
neutral  arbitrators,  consisting  of one  person  from  each  of the  following
categories:  (1) an attorney who has practiced in the area of commercial law for
at least 10 years or a retired judge at the Colorado or United  States  District
Court  or an  appellate  court  level:  (2) a  person  with at  least  10  years
experience  in  commercial  lending:  and (3) a  person  with  at  least 5 years
experience  in the  petroleum  industry.  The AAA shall submit a list of persons
meeting the criteria  outlined  above for each category of  arbitrator,  and the
parties shall select one person from each category in the manner  established by
the AAA.

                Section 9.05. Release. Upon full payment and satisfaction of the
Loan and all other amounts due in connection  therewith as provided herein,  the
parties  shall  thereupon  automatically  each be fully,  finally,  and  forever
released and  discharged  from any further  claim,  liability or  obligation  in
connection with the Loan.

                Section 9.06. No Waiver; Remedies. No failure on the part of the
Bank to exercise, and no delay in exercising, any right under the Loan Documents
shall operate as a waiver thereof;  nor shall any single or partial  exercise of
any right  under the Loan  Documents  preclude  any  other or  further  exercise
thereof or the exercise of any other right.  The  remedies  herein  provided are
cumulative and not exclusive of any remedies provided by law.

                Section 9.07.  Binding  Effect.  This Agreement shall be binding
upon and inure to the  benefit  of  Borrower  and the Bank and their  respective
successors and assigns,  except that Borrower shall not have the right to assign
its rights hereunder or any interest herein without the prior written consent of
the Bank.  The Bank may assign to one or more banks or other entities all or any
part of, or may grant  participations  to one or more banks or other entities in
or to all or any part of,  the Loan and the Note and,  to the extent of any such
assignment or participation  (unless otherwise stated therein),  the assignee or
participant of such assignment or  participation  shall have the same rights and
benefits  hereunder  and  under  the Note as it  would  have if it were the Bank
hereunder.

                Section 9.08. GOVERNING LAW AND SUBMISSION TO JURISDICTION.  THE
SUBSTANTIVE  LAW OF  COLORADO  SHALL  GOVERN  ALL THE TERMS AND  CONDITIONS  AND
INTERPRETATIONS  OF THE LOAN, THIS AGREEMENT,  THE NOTE AND, EXCEPT AS OTHERWISE
PROVIDED  IN THE LOAN  DOCUMENTS,  ALL  OTHER  LOAN  DOCUMENTS.  IN THE EVENT OF
LITIGATION  CONCERNING  THE LOAN,  THIS  AGREEMENT,  THE NOTE, OR THE OTHER LOAN
DOCUMENTS,  THE  PARTIES  HERETO  AGREE  THAT THE  EXCLUSIVE  VENUE AND PLACE OF
JURISDICTION  SHALL  BE THE  STATE  OF  COLORADO,  CITY AND  COUNTY  OF  DENVER,
INCLUDING  THE  UNITED  STATES  DISTRICT  COURT FOR THE  DISTRICT  OF  COLORADO.
FURTHER,  BORROWER  CONSENTS TO AND AGREES TO FILE A GENERAL  APPEARANCE  IN THE
EVENT IT RECEIVES A SERVICE OF PROCESS.

                Section 9.09.  Relationship to Other Documents. In the event any
provision hereof is in conflict with any provision of the Collateral  Documents,
the provisions hereof shall be controlling.

                IN  WITNESS  WHEREOF,   the  parties  hereto  have  caused  this
Agreement to be executed as of the date first above written.

May 15, 1997

Mr. Mark Hellerstein
President and CEO
St. Mary Land & Exploration Company
1776 Lincoln Street, Suite 1100
Denver, Colorado 80203

Dear Mark:

The purpose of this letter is to outline the basic terms and conditions,  agreed
to as of May 1,  1997,  whereby  Summo  Minerals  Corporation  ("SMC")  and  its
wholly-owned  subsidiary,   Summo  USA  Corp.  ("SUSA")  and  St.  Mary  Land  &
Exploration  Company  and  St.  Mary  Minerals  Inc.  ("St.  Mary")  propose  to
restructure  the  ownership  and finalize  financing of the Lisbon Valley Copper
Project  (the  "Project")  as  described  below   (collectively   the  "Proposed
Transaction").


(I)      Formation of Lisbon Valley Mining Company ("LVM")

         1.   LVM will  be  formed as a special purpose, U.S. domiciled, limited
              liability company to own and operate the Project.


(II)     SUSA Contributions to LVM

         1.   SMC  will   complete  a  private   placement   of  equity   and/or
              subordinated convertible debt for at least US$6.2 million and SUSA
              will contribute US$3.2 million in cash to LVM.

         2.   SUSA will  contribute all rights to the Project to LVM,  including
              the associated  Mining Contract,  the Construction  Contract,  the
              Acid  Contract,  the Power  Contract,  all  Project  permits,  and
              commitments from ING Capital Corporation and Heller Financial Inc.
              (the  "Banks")  for a US$45  million  senior  debt  facility  (the
              "Project Loan").

         3.   SMC/SUSA will provide a corporate guarantee of the Project Loan.

         4.   SUSA will contribute all rights to the Champion property to LVM.


(III)    St. Mary Contributions to LVM

         1.   St. Mary will contribute 9,924,093 SMC common shares to LVM.

         2.   St. Mary will contribute US$4.0 million in cash to LVM.

         3.   St. Mary will contribute a US$5.0 million letter of credit for the
              benefit of the Banks in  satisfaction  of the  Bank's  requirement
              that LVM maintain a US$5.0  million  Cash Reserve  Account for the
              life of the  Project  Loan.  St.  Mary will also  provide a US$3.6
              million  letter  of  credit  for  the  benefit  of  the  Banks  in
              satisfaction of the Bank's  requirement that LVM maintain a US$3.6
              million Project  Construction Cost Overrun Reserve account through
              completion of the Project.  If a letter of credit  provided by St.
              Mary is drawn upon by the Banks, the amount of any such draw shall
              be treated as a capital  contribution  by St. Mary to LVM and will
              be subject to the provisions of Section VI-3 below.

         4.   St. Mary  will contribute its 1.5% NSR in the Champion property to
              LVM.


(IV)     LVM Capital Calls


         1.   If LVM requires  additional  capital,  for example to fund Project
              construction   cost  overruns  or  for  Project   working  capital
              requirements,  LVM will  notify SUSA and St. Mary of the amount of
              the required capital contribution (a "LVM Capital Call") and their
              respective   share  of  the  LVM  Capital  Call,  which  shall  be
              calculated  in  accordance  with the sharing  ratios  described in
              Section VI below.  It is the expectation of SUSA and St. Mary that
              each party will fund its respective share of any LVM Capital Call.

         2.   SMC and  SUSA  agree,  if  necessary,  to  arrange  to fund  their
              proportionate  share of any LVM Capital  call through the issuance
              of a subordinated  convertible note to TIC in a maximum  principal
              amount  of $1.5  million  (the"TIC  Note").  The TIC Note  will be
              convertible  into SMC common  stock and  repayment of the TIC Note
              will be the sole responsibility of SMC/SUSA.

         3.   If SMC/SUSA is unable to fund its proportionate share of the first
              US$8.6  million of LVM Capital Calls pursuant to the provisions of
              Section IV-2 above, or otherwise, St. Mary agrees to loan SMC/SUSA
              its respective  share of such capital  call(s) for a period not to
              exceed 60 days at an annual  interest rate equal to the prime rate
              plus one percent (A "Capital Call Loan").  Capital Call Loans will
              be  subordinated  to the Project Loan,  SMC's US$3.0  million note
              obligation to Brown & Root, the TIC Note and  pari-passu  with any
              other senior indebtedness of SMC.

              If SUSA does not repay a Capital Call Loan within 60 days, St.Mary
              and  SMC  agree  that such loan  will be  extended  (an  "Extended
              Capital Call Loan") as follows:

              (a) SMC will grant St. Mary with a two-year warrant to acquire one
                  common share of SMC for each Cdn$2.00 of unpaid  principal and
                  accrued  interest  converted to an Extended Capital Call Loan.
                  Such common  stock  purchase  warrants  shall have an exercise
                  price equal to Cdn$1.25  (subject to  customary  anti-dilution
                  provisions).

              (b) An Extended Capital Call Loan shall have a maximum term of two
                  years,  shall  accrue  interest at an annual rate equal to 12%
                  and principal and interest shall be payable monthly.

              (c) At St. Mary's option, for a period of two years, the principal
                  amount of the Extended Capital Call Loan plus accrued interest
                  shall be (i)  convertible  (in  whole or in part)  into  SMC's
                  common stock at a conversion price equal to Cdn$1.25  (subject
                  to customary anti-dilution provisions), or alternatively, (ii)
                  exchangeable (in whole or in part) into an additional interest
                  in  LVM  which  will  increase  St.  Mary's  ownership  in the
                  profits,  losses and operating cash flows of LVM in accordance
                  with Section VI-3 below.

              (d) SMC agrees to provide St. Mary,  during the period in which an
                  Extended Capital Loan is outstanding, with a security interest
                  in SUSA's  ownership  interest  in LVM as well as SMC's  other
                  assets in an amount  equal to the  outstanding  principal  and
                  accrued interest under an Extended Capital Call Loan.

         4.   The  principal  amount  of  St. Mary's  letters of credit  will be
              reduced by the amount of any LVM Capital Call, with exception of a
              LVM Capital Call arising from an expansion of the Project.


(V)      Distribution of SMC Shares

         1.   The  SMC  common  shares  contributed  to  LVM by St. Mary will be
              distributed by LVM to SUSA.

         2.   SUSA will in turn distribute the SMC common shares to SMC.


(VI)     LVM Sharing Ratios


         1.   In  consideration  for its  contributions  to LVM,  St.  Mary will
              receive a 55% interest ("St.  Mary Sharing  Ratio") in the profits
              and losses, distributions of earnings and profits from operations,
              and voting rights of LVM.

         2.   In consideration for its contributions to LVM, SUSA will receive a
              45%  interest  ("SUSA  Sharing  Ratio") in the profits and losses,
              distributions of earnings and profits from operations,  and voting
              rights of LVM.

         3.   Additional  contributions  to LVM by St.  Mary or SUSA  which  are
              disproportionate  to the  original  Sharing  Ratios  set  forth in
              Section VI-1 and 2 above will receive credit equal to 125% of each
              such  disproportionate  contribution  for purposes of  calculating
              adjusted Sharing Ratios for SUSA and St. Mary.

         4.   The beginning stated capital  positions of St. Mary and SUSA which
              will be used as the base  line for  calculating  adjusted  Sharing
              Ratios in Section VI-3 above are calculated as follows:

              with  a  mutually  acceptable  mechanism  to be  specified  in the
              Operating Agreement.

         2.   The  Operating  Agreement  will  provide  that  affirmative  votes
              representing at least 65% of the ownership of LVM will be required
              to (i) approve LVM's annual  budgets,  (ii)  commence,  suspend or
              terminate  operations of the Project,  (iii) authorize the sale or
              disposition  of the Project  (concurrence  not to be  unreasonably

(VII)    Other Matters

         1.   St.  Mary and  SUSA  agree to  enter  into a  mutually  acceptable

              SUSA  a  non-transferable,  one-year  option  to  acquire  up to a
              maximum  5.1%  interest  in LVM from St.  Mary for a cash  payment
              equal to US$450,000 per each one percent  interest in LVM acquired
              by SUSA, up to a maximum of 5.1% interest in LVM for US$2,295,000.

         2.   SUSA  agrees to pay an annual  cash fee to St. Mary equal to 1% of
              the  outstanding   principal  amount  of  the  letters  of  credit
              contributed by St. Mary to LVM for the benefit of the Banks.  SUSA
              further   agrees  to   reimburse   St.   Mary  for  any  legal  or
              administrative  costs  incurred  by St.  Mary  in  arranging  such
              letters of credit.

         2.    Subject to (a)the rights of Lisbon Copper Ltd. under that certain
               Second  Amendment of Option Agreement dated December 4, 1997, (b)
               the  rights  of  the  lessors  of  the  leases  included  in  the

               person has or claims any  interest  in any  Collateral  except as
               previously approved in writing by Secured Party.  Nothing in this
               Section (B)(2),  however,  shall be deemed to be a representation
               or a warranty that any of the unpatented mining claims contains a
               discovery of minerals.  Debtors will defend any proceeding  which
               may affect title to or Secured Party's  security  interest in any
               Collateral,  and will  indemnify  Secured Party for all costs and
               expenses of Secured Party's  defense.  The Collateral will not be

               Party, and will at any time or times hereafter perform such other
               acts as Secured Party may request to establish, maintain, perfect
               and enforce its security interest in the Collateral.

               Debtors will give  Secured  Party  prompt  written  notice of any
               change of  location  of the  Collateral  and of any change of any
               Debtor's chief  executive  office or name. The Collateral is used
               or bought primarily for use in business.

         5.    Debtors  will pay when due all existing and future charges, liens
               and  encumbrances  on  and  all  taxes  and  assessments  now  or

         6.    Debtors at their expense at all times shall insure the Collateral
               against loss or damage from such  casualties as Secured Party may
               require,  with such  insurance  company  or  companies  as may be
               satisfactory  to  Secured  Party,  with loss  payable  to Secured
               Party. Secured Party may apply any such insurance proceeds to any
               of the Debt, whether or not then due and payable.

         7.    Debtors will provide Secured Party with any information regarding
               the  Collateral  or Debtors  which Secured Party may request from
               time to time.  All  information  at any time  supplied to Secured
               Party by Debtors  (including,  but not  limited to, the value and
               condition  of   Collateral,   financial   statements,   financing
               statements,  and statements made in documentary  Collateral),  is

               Debtor's  premises  to give  notice of Secured  Party's  security
               interest  in,  and to  collect  Collateral  and  proceeds  and to
               execute and file in each Debtor's  name any financing  statements
               and  amendments  thereto  required  to  perfect  Secured  Party's
               security  interest  hereunder,  all to protect and  preserve  the
               Collateral and Secured  Party's rights  hereunder.  Secured Party
               may:  (a)  Endorse,  collect and  receive  delivery or payment of
               instruments  and  documents  constituting  Collateral;  (b)  Make
               extension  agreements  with respect to or  affecting  Collateral,
               exchange it for other Collateral,  release persons liable thereon
               or take security for the payment thereof, and compromise disputes
               in connection  therewith;  (c) Use or operate  Collateral for the
               purpose of preserving  Collateral or its value and for preserving
               or liquidating Collateral.

         9.    Discharge  of any Debtor or other obligor of the Debt ("Obligor")
               except for full payment,  or any extension or forbearance for the
               benefit of any Debtor or Obligor, or any impairment or suspension
               of Secured Party's rights against a Debtor or Obligor,  shall not
               affect the  liability  of or Secured  Party's  rights or remedies
               against any other Debtor or Obligor or the Collateral.  Until the
               Debt shall have been paid or performed in full,  Secured  Party's
               rights  shall  continue  notwithstanding  any  change  of rate of
               interest, or acceptance, release or substitution of Collateral or
               any  transfer of a Debtor's  interest  to another,  or any bar of
               rights or  remedies  by  statutes  of  limitation  or  otherwise.
               Debtors  waive (a) any right to require  Secured  Party to pursue
               any remedy; (b) presentment, protest and notice of protest, sale,
               and  advertisement of sale; (c) any right to the benefit of or to
               direct the  application  of any  Collateral  until the Debt shall
               have been paid; and (d) any right of subrogation to Secured Party
               until all Debt shall have been paid or performed in full.

(C)  Defaults and Remedies; Non-waiver.

               of Default" as defined in the Note;  (b) Failure of any Debtor or
               Summo  Minerals   Corporation  to  perform  or  comply  with  any
               agreement,  condition or provision in this agreement, the Note or
               any other  instrument or document  between either  Debtor,  Summo
               Minerals   Corporation,   Secured   Party  or  St.  Mary  Land  &
               Exploration  Company;  (c) Any adverse  change in any Debtor's or
               Obligor's  financial  condition which in Secured Party's judgment
               impairs the prospect of payment or performance; (d) Any actual or

               reasonably anticipated  deterioration of the Collateral or in the
               market price thereof which causes it in Secured Party's  judgment
               to become unsatisfactory as security.

         2.    Upon any default hereof, at  Secured Party's sole option, without
               demand or notice,  all or any part of the Debt shall  immediately
               become due.  Secured Party shall have all rights provided by this
               agreement or provided by law,  including  the Uniform  Commercial
               Code,  and may sell  Collateral  in one or more sales or exercise
               its self-  help right to  repossess  the  Collateral.  At Secured
               Party's  option,  any such sale may be  conducted in any locality
               where Secured  Party or any Debtor has an office.  Sales for cash
               or on credit to a wholesaler, retailer or user of the Collateral,
               or at public or private auction, shall all be deemed commercially
               reasonable.  Secured Party may require  either Debtor to assemble
               the  Collateral and make it available to Secured Party at a place
               designated by Secured Party which is reasonably convenient to the
               parties.  Secured  Party's  acceptance  of partial or  delinquent
               payments  or failure of Secured  Party to  exercise  any right or
               remedy at any time shall not waive any  obligation  of any Debtor
               or Obligor,  or any right or remedy of Secured  Party,  or modify
               this agreement, or waive any other similar default.

(D)  General Provisions.

         1.    On transfer  of  all  or any  part of the Debt, Secured Party may
               transfer  all  or  any  part  of  the  security  interest  in the
               Collateral.  Secured  Party  may  deliver  all or any part of the
               Collateral  to any  Debtor  at any  time.  Any such  transfer  or
               delivery  shall  discharge  Secured  Party from all liability and
               responsibility  with respect to such  Collateral  transferred  or
               delivered. This agreement benefits Secured Party's successors and
               assigns and binds each  Debtor's  successors  and  assigns.  Each
               Debtor agrees not to assert against any assignee of Secured Party
               any claim or defense it may have against  Secured Party.  Time is
               of the essence.  Debtors will execute any additional  agreements,
               assignments  or documents  which  Secured  Party  reasonably  may
               request to  effectuate  this  agreement  or perfect any rights or
               interests, including, without limitation, any mortgage or deed of
               trust with respect to the Utah Property.

         2.    Captions,   titles  and  section  and  paragraph  divisions  and 
               arrangements  in  this  agreement  and  in  any  instruments  and
               documents  heretofore  or  hereafter  made  or  executed  are for
               convenience  and for  reference  only,  and shall not  affect the
               meaning,  interpretation  or construction  thereof.  Whenever the
               context so requires the singular  number shall include the plural
               and the plural shall include the singular, as applicable.

         3.    This agreement shall be governed by and  construed  in accordance
               with the laws of the State of Colorado.

features now or hereafter located on, in, under or above the Property; and

         j. All surface,  subsurface,  development and mining rights  associated
with the Property, whether now or hereafter created; and

         k. All other or greater  rights and  interests of every nature in, with
respect to or related to the Property or in the possession or use thereof and in
the income therefrom, whether now owned or subsequently acquired by Grantor.

         TO HAVE AND TO HOLD such Property unto Trustee, subject only to (a) the
rights of Lisbon  Copper Ltd.  under that  certain  Second  Amendment  of Option
Agreement  dated  December 4, 1997,  (b) the rights of the lessors of the leases
included in the Property,  (c) the paramount rights of the United States and (d)
the liens and  encumbrances of Beneficiary and liens and  encumbrances of record
on the date hereof (hereinafter referred to as the "Permitted Exceptions");  and
Grantor  does  hereby bind  itself,  its  successors  and assigns to warrant and
forever defend,  all and singular,  such Property unto Trustee,  its successors,
substitutes and assigns, against all persons whomsoever claiming or to claim the
same or any part thereof.

         Section 1.2. Security  Agreement.  Grantor makes the foregoing grant to
Trustee to hold the Property in trust for the benefit of Beneficiary and for the
purposes  and  upon  the  terms  and  conditions  hereinafter  set  forth.  This
instrument  is and  shall  be  construed  as both a Deed of Trust  and  Security
Agreement  and to the extent  that any of the  Property,  including  but without
limitation,  the Collateral,  is deemed to be personal property or fixtures,  or
property not subject to an encumbrance  upon real estate,  Grantor hereby grants
unto Beneficiary a security interest in and to such property.

         Section 1.3.  Release.  If Grantor shall pay or cause to be paid to the
holder of the Note  (defined  below) the  principal  and  interest to become due
thereupon  at the time and in the manner  stipulated  therein,  and shall pay or
cause to be paid all other sums payable  hereunder and all  indebtedness  hereby
secured,  then, in such case, the estate,  right,  title and interest of Trustee
and Beneficiary in the Property shall cease, terminate and become void, and upon
proof being given to the  satisfaction  of Beneficiary  that the Note,  together
with interest thereon have been paid or satisfied, and upon payment of all fees,
costs,  charges,  expenses  and  liabilities  chargeable  or  incurred  or to be
incurred by Trustee or  Beneficiary,  and of any other sums as herein  provided,
this  conveyance  shall be  released  in due  form at the  expense  of  Grantor,
otherwise it shall remain in full force and effect.

Summo USA Corporation to Beneficiary,  now or hereafter  arising under the terms
hereof or in any other instrument constituting additional security for the Note;
and

         c. The performance by Grantor,  Summo Minerals Corporation or Summo USA

Grantor may contest the validity of any tax or assessment  which it is obligated
to pay  under  the  terms  of this  Deed  of  Trust  by  appropriate  legal  and
administrative  proceedings.  No default shall be declared  hereunder as long as
Grantor, in good faith, and by appropriate proceedings, is contesting the amount
or validity of such tax,  assessment or charge;  provided  that Grantor,  before
instituting any such contest, gives Beneficiary notice of its intention to do so
and so long as the  proceedings  maintained by Grantor at all times  effectively

otherwise.  Upon  conclusion of any such  proceedings,  Grantor shall  forthwith
discharge any liability for taxes and  assessments  and all penalties,  interest
and costs in connection therewith.

may be  reasonably  required.  Any  improvements  on the  Property  shall not be
removed,  demolished or substantially  altered without the prior written consent
of  Beneficiary.  Grantor  shall  pay all  claims  for labor  performed  and for
materials furnished for any such improvements when due. Grantor shall not commit
any waste or permit  impairment or deterioration of the Property.  Grantor shall
not make any change in the use of the Property without the prior written consent

         Section 6.2. Waiver of Subrogation. The policy must contain a provision
to the effect that any waiver of subrogation rights by the insured does not void
the coverage and any other special  endorsements as may be required by the terms
of any leases assigned as security for the indebtedness  secured by this Deed of
Trust.

         Section 6.3.  Delivery of Policies.  Grantor shall deliver all policies
and certificates,  including additional and renewal policies,  to Beneficiary or
other  evidence of the  existence of such  insurance  which is  satisfactory  to
Beneficiary and, in the case of insurance about to expire, shall deliver renewal

expiration.  A  certificate  as to liability  coverage,  as  distinguished  from
submission of original policies, will be acceptable.

shall immediately  notify  Beneficiary  whenever any such separate  insurance is
taken out and shall promptly  deliver to Beneficiary true and complete copies of
the policy or  policies  of such insur ance.  In the event of a  foreclosure  or
other transfer of title to the Property in lieu of  foreclosure,  or by purchase
at the foreclosure  sale, all interest in any insurance  policies in force shall
pass to Beneficiary, transferee or purchaser as the case may be.


                                  ARTICLE VII.
                            CASUALTY OR CONDEMNATION

         Section 7.1. Casualty. Grantor shall promptly notify Beneficiary of any
loss  whether  covered by insurance or not. In case of loss or damage by fire or
other  casualty,  Beneficiary  is authorized  (i) to settle and adjust any claim
under  insurance  policies  which  insure  against  such  risks or (ii) to allow
Grantor to agree with the  insurance  company or  companies  on the amount to be
paid in regard to such  loss.  In either  case,  Beneficiary  is  authorized  to
collect and receipt for any such insurance money.  Such insurance  proceeds may,
at the  option of  Beneficiary,  in the event of a total  loss be applied in the
reduction of the indebtedness secured hereby, whether due or not; if less than a
total loss, such proceeds shall be held by Beneficiary  without any allowance of
interest  and,  if an Event of Default  does not then exist and if no  condition
then exists which will, with the passage of time, the giving of notice, or both,
constitute an Event of Default,  shall be used to reimburse Grantor for the cost
of re building or restoration of the buildings or improvements on the Property.

         Section 7.2. Loss During Foreclosure. In case of loss after foreclosure
proceedings have been instituted and not cured or redeemed,  the proceeds of any
such insurance policy or policies,  if not applied as aforesaid in rebuilding or
restoring the buildings or improvements, shall be used to pay the

                                        7

<PAGE>



amount due  Beneficiary  and the balance,  if any, shall be paid to the owner of
the equity of  redemption if he shall then be entitled to the same. In case of a
judicial  foreclosure of this Deed of Trust, the court in its decree may provide
that the mortgagee's  clause attached to each of said insurance  policies may be
canceled and that the decree creditor may cause a new loss clause to be attached
to each of said  policies  making the loss  thereunder  payable  to said  decree
creditor;  and any such  foreclosure  decree may further provide that in case of
one or more redemptions under said decree,  pursuant to the statute in such case
made and provided,  then and in every such case, each successive  redemptory may
cause the preceding loss clause attached to each insurance policy to be canceled
and a new loss clause to be attached hereto,  making the loss thereunder payable
to such  redemptory.  In the event of  foreclosure  sale,  Beneficiary is hereby
authorized, without consent of Grantor, to assign any and all insurance policies
to the  purchaser at the sale,  or to take such other steps as  Beneficiary  may
deem  advisable,  to cause the interest of such purchaser to be protected by any
of the said insurance policies.

         7.3. Condemnation. Grantor, immediately upon obtaining knowledge of the
institution  of any  proceeding  for the  condemnation  of the  Property  or any
portion  thereof,  shall notify  Beneficiary  of the pendency  thereof.  Grantor
hereby  assigns,  transfers  and sets over unto  Beneficiary  all  compensation,
rights of action, the entire proceeds of any award and any claim for damages for
any of the  Property  taken or damaged  under the power of eminent  domain or by
condemnation  or by  sale in  lieu  thereof.  Beneficiary  may,  at its  option,
commence,  appear in and  prosecute,  in its own name or in the name of Grantor,
any action or  proceeding,  or make any  compromise  or settlement in connection
with such  condemnation,  taking under the power of eminent  domain,  or sale in
lieu  thereof.  After  deducting  therefrom  all  of  its  expenses,   including
attorneys'  fees,  Beneficiary may elect to apply the proceeds of the award upon
or in reduction of the indebtedness secured hereby,  whether due or not, or hold
such proceeds without any allowance of interest and make such proceeds available
for  restoration  or re  building  of the  Property.  If the  proceeds  are made
available by Beneficiary to reimburse Grantor for the cost of such rebuilding or
restoration,  any surplus  which may remain out of such award  after  payment of
such cost of rebuilding or  restoration  shall at the option of  Beneficiary  be
applied on account of the  indebtedness  secured  hereby or be paid to  Grantor.
Grantor agrees to execute such further assignments of any compensation,  awards,
damages, rights of action and proceeds as Beneficiary may require.


                                  ARTICLE VIII.
                   MECHANICS' OR OTHER LIENS AND ENCUMBRANCES

         Section  8.1.  No Liens.  Grantor  shall pay when due all  obligations,
lawful  claims or demands of any person  which,  if unpaid,  might result in, or
permit the creation of, a lien or encumbrance on the Property, the Collateral or
on the rents,  issues,  income and profits arising therefrom,  whether such lien
would be senior or  subordinate  hereto,  including,  but without  limiting  the
generality of the foregoing, all claims of mechanics,  materialmen, laborers and
others for work or labor  performed,  or  materials  or  supplies  furnished  in
connection  with  any  work  of  demolition,   alteration,   improvement  of  or
construction upon the Property.  Grantor shall not mortgage,  pledge,  assign or
otherwise create, or

                                        8

<PAGE>



permit the creation of, any security  interest in the Property or the Collateral
other than created hereby, whether superior or subordinate,  without the express
prior written permission of Beneficiary.

         Section 8.2. Right to Contest.  Grantor shall have the right to contest
in good faith the  validity  of any such lien or  encumbrance  provided  Grantor
shall first deposit with  Beneficiary a bond or other security  satisfactory  to
Beneficiary in such amount as Beneficiary shall reasonably  require but not more
than one hundred  fifty  percent  (150%) of the amount of the claim and provided
further that Grantor shall thereafter  diligently  proceed to cause such lien to
be removed and  discharged.  If Grantor  shall fail to discharge  any such lien,
then, in addition to any other right or remedy of Beneficiary,  Beneficiary may,
but shall not be obligated  to,  discharge  the same either by paying the amount
claimed to be due or by  depositing  in court a bond in the amount  required  by
statute,  or otherwise  giving security for such claim, or by taking such action
as may be prescribed by law.  Grantor shall guard every part of the Property and
Collateral from removal, destruction and damage and shall not do or suffer to be
done any act whereby the value of any part of the Property may be lessened.

         Section  8.3.  Beneficiary  Right  to  Intervene.  If the  interest  of
Beneficiary in the Property or the superiority of such interest is endangered or
attacked,  directly or indirectly,  Grantor hereby  authorizes  Beneficiary,  at
Grantor's  expense,  to take all  necessary  and proper steps for the defense of
such interest or the superiority  thereof,  including the employment of counsel,
the  prosecution  or defense of  litigation,  and the compromise or discharge of
claims made against such interest or the superiority thereof.


                                   ARTICLE IX.
                               ASSIGNMENT OF RENTS

         Section  9.1.   Assignment.   Grantor  hereby  absolutely  assigns  and
transfers to Beneficiary all of the rents, royalties, issues, profits, revenues,
income and other benefits  ("Rents and Profits") of the Property or arising from
the  use  and  enjoyment  of all or any  portion  thereof.  Grantor  irrevocably
appoints  Beneficiary  its  special  attorney-in-fact  to demand,  receive,  and
enforce payment, to give receipt, release, and satisfaction,  and to sue, in the
name of Grantor or Beneficiary,  for all such Rents and Profits and to apply the
same to the indebtedness secured hereby.

         Section 9.2. Collection.  Notwithstanding the above, Grantor shall have
the right to collect,  use and enjoy such Rents and Profits prior to an Event of
Default  under this Deed of Trust or the Note.  Upon any Event of Default  under
this Deed of Trust or the Note,  Beneficiary  may enter upon and take possession
of the Property and collect such Rents and Profits, including those past due and
unpaid,  and apply the same,  less  costs and  expenses,  upon any  indebtedness
secured  hereby,  and in  such  order  and to  such  notes  as  Beneficiary  may
determine.  Grantor  shall not  execute,  without the prior  written  consent of
Beneficiary,  an assignment or transfer of any of its right,  title and interest
in the Rents and Profits.

                                   ARTICLE X.
                         SALE OF PROPERTY OR COLLATERAL

         Section  10.1.  Due on Sale.  If the  Property  or any part  thereof or
interest therein,  whether legal or equitable,  is sold, assigned,  transferred,
conveyed,  mortgaged, or otherwise alienated by Grantor,  whether voluntarily or
involuntarily  or by  operation  of law,  or that if the  management  thereof is
changed in either or any case without the prior written  consent of Beneficiary,
Beneficiary,  at its  option,  may  declare  the Note and all other  obligations
secured hereunder to be forthwith due and payable.  Any change in the beneficial
ownership  of Grantor or in the legal or  equitable  title of the Property or in
the beneficial  ownership of the Property,  whether or not of record and whether
or not for  consideration  or sale, shall be deemed a transfer of an interest in
the Property.

         Section 10.2. Beneficiary Right to Deal with Transferee;  No Release of
Grantor.  In the event  ownership of the  Property or any part  thereof  becomes
vested in a person or persons  other than  Grantor,  without  the prior  written
approval of Beneficiary,  Beneficiary may, without notice to Grantor, waive such
default and deal with such successor or successors in interest with reference to
this Deed of Trust and the Note in the same manner as with  Grantor,  without in
any way releasing,  discharging or otherwise  affecting the liability of Grantor
hereunder or under the indebtedness hereby secured. No sale of the Property,  no
forbearance on the part of Beneficiary, no extension of the time for the payment
of the indebtedness  hereby secured or any change in the terms thereof consented
to by  Beneficiary  shall in any way whatsoever  operate to release,  discharge,
modify,  change or affect the original  liability of Grantor  herein,  either in
whole or in part.  Any deed  conveying  the  Property  or any part  thereof,  if
approved by  Beneficiary in writing,  shall provide that the grantee  thereunder
assumes all of Grantor's  obligations under this Deed of Trust, the Note and all
other  Security  Documents.  In the event  such  deed  shall  not  contain  such
assumption,  Beneficiary  shall have all rights  reserved to it hereunder in the
event of a default or if Beneficiary shall not elect to exercise such rights and
remedies,  the  grantee  under  such deed shall  nevertheless  be deemed to have
assumed  such  obligations  by acquiring  the  Property or such portion  thereof
subject to this Deed of Trust.

         Section 10.3. Collateral. Grantor shall not voluntarily,  involuntarily
or by  operation  of law sell,  assign,  transfer  or  otherwise  dispose of the
Collateral or any interest therein and shall not otherwise do or permit anything
to be done or occur that may impair the Collateral as security  hereunder except
that so long as this Deed of Trust is not in default, Grantor shall be permitted
to sell or  otherwise  dispose  of the  Collateral  when  absolutely  worn  out,
inadequate,  unserviceable  or  unnecessary  for  use  in the  operation  of the
Property in the conduct of the business of Grantor,  upon  replacing the same or
substituting  for the  same  other  Collateral  at  least  equal in value to the
initial value of that  disposed of and in such a manner so that such  Collateral
shall  be  subject  to the  security  interest  created  hereby  and so that the
security interest of Beneficiary  hereunder shall be the first priority security
interest in the Collateral. Nothing in this Section 10.3, however, shall prevent
Grantor from  abandoning  any unpatented  mining claims when Grantor  reasonably
determines  that such claims are no longer  necessary  for the  operation of the
Property. In the event the Collateral is sold in connection with the sale of the
Property,  Grantor  shall  require,  as a condition of the sale,  that the buyer
specifically  agree to assume Grantor's  obligations as to the security interest
herein granted and to

<PAGE>



execute  whatever  agreements  and filings  deemed  necessary by  Beneficiary to
maintain its perfected security interest in the Collateral.

                                   ARTICLE XI.
                                 INDEMNIFICATION

         Grantor  shall  appear in and  defend  any suit,  action or  proceeding
arising out of or in connection  with the Property,  the  Collateral,  the Note,
this Deed of Trust or the other Security Documents that might in any way, in the
sole judgment of Beneficiary, affect the value of the Property, the title to the
Property,  the validity,  lien or priority of any of the Security Documents,  or
the rights and powers of Trustee or  Beneficiary.  Grantor shall,  at all times,
indemnify,  hold harmless and on demand,  reimburse  Beneficiary for any and all
liability,  loss, damage,  expense or cost,  including cost of evidence of title
and  attorneys'  fees,  arising out of or incurred in  connection  with any such
suit,  action or  proceeding.  Grantor  shall pay the cost of  collection of any
indebtedness secured hereby,  including  reasonable  attorneys' fees, whether or
not suit is brought and shall pay reasonable  cost of suit,  cost of evidence of
title and  reasonable  attorneys'  fees in any  proceeding  or suit  brought  by
Trustee or Beneficiary  to foreclose  this Deed of Trust.  Grantor shall further
pay all cost and expense, including attorneys' fees, which Beneficiary may incur
in  connection  with any other effort or action  (whether or not  litigation  or
foreclosure is involved) to enforce or defend  Beneficiary's rights and remedies
under  each  and  every  one of the  Security  Documents.  The  sum of any  such
expenditures  shall be  secured  by this Deed of Trust  and the  other  Security
Documents  and shall bear  interest at the Default Rate provided in the Note and
shall be due and payable on demand.


                                  ARTICLE XII.
                            PRESERVATION OF PROPERTY

         If Grantor  fails to make any  payment or do any act  required  by this
Deed of  Trust  or the  Note or by any  prior  encumbrance,  lien,  reservation,
restriction,  condition,  or covenant  affecting the Property,  then Beneficiary
may, without obligation or notice,  make any payment or do any act to the extent
necessary to protect the  Property.  In so doing,  Grantor shall not be released
from any  obligation  created  under this Deed of Trust.  Any  payments  made by
Beneficiary and the costs and expenses,  including  attorneys' fees, incurred by
Beneficiary by doing any act as provided in this article shall become additional
principal  under the Note and shall bear  interest at the Default Rate and shall
be  immediately  due and payable from  Grantor to  Beneficiary.  Nothing  herein
contained  shall prevent any such failure to perform on the part of Grantor from
constituting an Event of Default (as hereinafter defined).


                                  ARTICLE XIII.
                      PERFORMANCE UNDER SECURITY DOCUMENTS

         Grantor  will  promptly  and  strictly  perform  and  comply  with  all
agreements,  covenants,  conditions  and  prohibitions  required of, made by, or
imposed  upon  Grantor  under the  terms of each and  every one of the  Security
Documents.  In the event  Grantor  suffers  or  permits  to occur any  breach or
default under the  provisions of any of the Security  Documents,  such breach or
default  shall con  stitute an Event of Default  hereunder  and at the option of
Beneficiary,  and without notice to Grantor,  all unpaid indebtedness secured by
this Deed of Trust shall  become due and payable as in the case of other  Events
of  Default.  Grantor  will  further,  from  time  to  time  at the  request  of
Beneficiary,  supply  Beneficiary with a current  inventory of the Collateral in
such detail as Beneficiary may require.


                                  ARTICLE XIV.
                                EVENTS OF DEFAULT

         Any one or more of the following  events shall be deemed to be an Event
of Default hereunder as well as under the Note and the Security Documents:

         Section 14.1.  Default Under Note. Any "Event of Default" as defined in
the Note.

         Section  14.2.  Failure to Perform.  The failure by Grantor to properly
and timely  perform,  comply  with,  or observe any of the  non-monetary  terms,
covenants, conditions or agreements in the Note, this Deed of Trust or any other
Security  Documents  and such  failure  continues  for more than ten days  after
notice thereof from Beneficiary.

         Section 14.3.  Condemnation.  The taking of the Property or any portion
thereof  through  condemnation  (which term when used herein  shall  include any
damage or taking by any governmental authority or any other authority authorized
by the laws of the  state  where the land is  located  or the  United  States of
America)  either  temporarily  or for a period in excess of thirty (30) days, or
permanently.

         Section 14.4.  Priority Lien Claim. The assertion  (except by the owner
of an encumbrance expressly excepted from Grantor's warranty of title herein) of
any claim of priority  over this Deed of Trust,  by title,  lien,  or otherwise,
unless within thirty (30) days after such  assertion  either  Grantor causes the
assertion to be withdrawn or  Beneficiary  approves of such claim of priority in
writing.

         Section 14.5. Dissolution. The dissolution, termination, or liquidation
of Grantor or of any other person or entity  directly or  indirectly  liable for
the payment of the Note.

         Section 14.6.  Other. The occurrence of any other event designated as a
default or an Event of Default  under any other  provision of this Deed of Trust
or in any of the Security Documents.

                                    REMEDIES

         Immediately  upon or at any time  after  the  occurrence  of any of the
Events of Default as defined in Article  XIV of this Deed of Trust,  Beneficiary
may exercise any one or more of the  cumulative,  concurrent,  and  nonexclusive
remedies  which  are  listed  below or which are  listed  in any other  Security
Document or which are  otherwise  available at law or in equity  whether like or
unlike the  remedies so listed,  and  Beneficiary  may  exercise  such remedy or
remedies  in such  sequence or  combination  as  Beneficiary  may  determine  in
Beneficiary's sole discretion:

         Section   15.1.   Performance   of  Defaulted   Obligations.   Although
Beneficiary shall not be required to do so,  Beneficiary may make any payment or
perform any other  obligation  under the Note,  this Deed of Trust or any of the
Security  Documents  which  Grantor has failed to make or  perform,  and Grantor
hereby irrevocably  appoints  Beneficiary as a true and lawful  attorney-in-fact
for  Grantor  with  authority  to make any such  payment  and  perform  any such
obligation  in the name of Grantor and on behalf of Grantor.  All payments  made
and expenses  (including  attorneys'  fees) incurred by Beneficiary  pursuant to
this section,  together with interest thereon at the Default Rate (as defined in
the Note) from the date paid or incurred until repaid, will be part of Grantor's
indebtedness  to Beneficiary  and will be immediately due and payable by Grantor
to  Beneficiary  or,  at  Beneficiary's  election,  may be added  to the  unpaid
principal balance of the Note and shall be secured by this Deed of Trust and the
other Security Documents.  In lieu of advancing Beneficiary's own funds for such
purposes, Beneficiary may use any funds of Grantor which may be in Beneficiary's
possession, including but not limited to undisbursed loan proceeds, insurance or
condemnation  proceeds, and amounts deposited for other purposes. Any payment by
Beneficiary  made  pursuant to this section or in any other section of this Deed
of Trust or of the Note or any  other  Security  Document  shall  not  excuse or
constitute a waiver by Beneficiary of any default by Grantor.

         Section   15.2.    Specific    Performance   and   Injunctive   Relief.
Notwithstanding  the  availability  of  legal  remedies,  Beneficiary  shall  be
entitled to obtain  specific  performance,  mandatory or prohibitory  injunctive
relief,  or other  equitable  relief  requiring  Grantor to cure or refrain from
repeating any default.

         Section 15.3.  Acceleration of Secured  Obligations.  Beneficiary  may,
without notice or demand,  declare all of Grantor's  indebtedness to Beneficiary
secured  hereunder  or by any of the  Security  Documents  immediately  due  and
payable in full,  including,  but not  limited to, the entire  unpaid  principal
balance of the Note and all unpaid interest accrued thereon.

         Section  15.4.  Possession  of  Property.  In the case of any  Event of
Default or upon the  abandonment  thereof by Grantor,  Beneficiary may enter and
take possession of the Property  without seeking or obtaining the appointment of
a receiver, may employ a managing agent for the Property, and may operate, lease
or rent all or any part of the Property,  either in Beneficiary's name or in the
name of Grantor, and may collect the rents, issues, and profits of the Property.
Any revenues collected

by  Beneficiary  under this section will be applied first toward  payment of all
costs and  expenses  (in  cluding  attorneys'  fees)  incurred  by  Beneficiary,
together with interest thereon at the Default Rate (as defined in the Note) from
the date paid or incurred  until repaid,  then to late charges,  if any, then to
accrued  interest and the balance,  if any,  will be applied  against  Grantor's
indebtedness  to Beneficiary and principal under the Note until it has been paid
in full.

         Section  15.5.  Enforcement  of  Security  Interests.  Beneficiary  may
exercise all rights of a secured  party under the Utah Uniform  Commercial  Code
with respect to all or any part of the  Collateral,  including,  but not limited
to, taking  possession of, holding,  and selling the Collateral and enforcing or
otherwise  realizing upon any other property in which Beneficiary has a security
interest.  Any  requirement  for reasonable  notice of the time and place of any
public sale or of the time after which any private sale or other  disposition is
to be made will be satisfied by  Beneficiary's  giving of such notice to Grantor
at least five days prior to the time of any public  sale or the time after which
any private sale or other intended disposition is to be made.

         Section 15.6.  Foreclosure Against Property.  Beneficiary may foreclose
this Deed of Trust, insofar as it encumbers the Property,  including Collateral,
either by judicial action or through Trustee.  Foreclosure  through Trustee will
be  initiated  by the filing with Trustee of a Notice of Election and Demand for
Sale.  Trustee  shall then comply with such notice  requirements  of the laws of
Utah as then apply with respect to such sale and shall file the required  notice
for  record in each  county  wherein  the  Property  or any  portion  thereof is
situated. Beneficiary shall also deposit with Trustee the Note and all documents
evidencing the indebtedness and expenditures secured hereby.  Trustee shall then
proceed to foreclosure and shall sell and dispose of the Property, including the
Collateral (en masse or in separate parcels,  as Trustee may think best), in the
manner then provided by applicable  law. Any sale conducted by Trustee  pursuant
to this section may be conducted at any door or entrance to, or room within, any
building  temporarily or permanently being used as a courthouse in the county in
which the real property described in Exhibit A hereto is located or at or within
any  building  in which the office of the clerk and  recorder  of said county is
then  located  or at any  other  location  then  permitted  by  applicable  law;
provided,  however,  that the actual  place of sale shall be  designated  in the
Notice of Sale. Beneficiary may purchase the Property, including the Collateral,
or any part thereof,  and may bid in any part or all of the indebtedness secured
hereby and it shall not be obligatory upon the  purchaser(s) at any such sale to
see to the  application of the purchase  money.  The person  conducting the sale
may, for any cause he deems  expedient,  postpone the sale from to time until it
shall be completed and, in every case notice of  postponement  shall be given by
public  declaration  thereof by such person at the time and place last appointed
for the sale; provided,  if the sale is postponed for longer than one day beyond
the date designated in the Notice of Sale,  notice thereof shall be given in the
same manner as the original Notice of Sale. Nothing in this section dealing with
foreclosure   procedures  or  specifying  particular  actions  to  be  taken  by
Beneficiary  or by  Trustee  shall  be  deemed  to  conflict  with  the  minimum
requirements  or procedures  now or hereafter  specified or provided by Utah law
and any such conflict shall be resolved in favor of the requirements of Utah law
applicable at the time of foreclosure.

         Section 15.7.  Expenses of Trustee's Sale or Foreclosure.  In the event
all or any  part  of the  Property  shall  be sold by  Trustee  pursuant  to the
provisions  of this  article  or in the event  that this Deed of Trust  shall be
foreclosed  by  appropriate  proceedings  in a court of competent  jurisdiction,
there shall be allocated and included as part of the obligations secured hereby,
together with interest thereon at the Default Rate (as defined in the Note), all
expenses which may be paid or incurred by or on behalf of Trustee or Beneficiary
as court costs,  filing fees,  attorneys' fees,  appraisers'  fees,  outlays for
documentary and expert evidence, stenographers' charges, mailing and publication
costs,  costs for service of process,  and costs  (which may be  estimates as to
items to be expended  after entry of the decree) of procuring all such abstracts
of title,  foreclosure  certificates,  title  searches and  examinations,  title
insurance  policies,  and similar data and  assurances  with respect to title as
Beneficiary  may deem reasonably  necessary  either to prosecute such suit or to

         Section 15.9.  Appointment of Receiver.  Beneficiary shall be entitled,
as a matter of right and  without  regard to the value of any  security  for the
indebtedness secured hereunder or by any of the other Security Documents, or the
solvency  of any  person or entity  liable  therefor,  to the  appointment  of a
receiver for the Property  upon ex parte  application  to any court of competent
jurisdiction, or otherwise. Grantor freely and knowingly waives any right to any
hearing  or notice of  hearing  prior to the  appointment  of a  receiver.  Such
receiver and his/her  agents shall be empowered:  (a) to take  possession of the
Property  and any and all assets used in  connection  therewith;  (b) to exclude
Grantor and Grantor's agents,  servants, and employees from the Property; (c) to
collect the rents,  issues,  profits,  and income therefrom;  (d) to operate the
Property and complete any construction which may be in progress;  (e) to do such
maintenance  and  make  such  repairs  and  alterations  as the  receiver  deems
necessary;  (f) to use  all  stores  of  materials,  supplies,  and  maintenance
equipment  on  the  Property  and  replace  such  items  at the  expense  of the
receivership  estate; (g) to pay all taxes and assessments against the Property,
all premiums for insurance  thereon,  all utility and other operating  expenses,
and all sums due under any prior or subsequent encumbrance; and (h) generally do
anything  which  Grantor  could  legally do if Grantor were in possession of the
Property.  All  expenses  incurred  by the  receiver  or  his/her  agents  shall
constitute a part of the indebtedness  secured  hereunder or by any of the other
Security  Documents.  Any revenues  collected  by the receiver  shall be applied
first to the expenses of the receivership, including attorneys' fees incurred by
the receiver and by Beneficiary,  together with interest  thereon at the Default
Rate (as defined in the Note) from the date first paid or incurred until repaid,
and the balance shall be applied toward the indebtedness secured hereunder or by
any of the other Security  Documents or in such other manner as the receivership
court  may  direct.  Unless  sooner  terminated  with  the  express  consent  of
Beneficiary, any such receivership shall continue until the indebtedness secured
hereunder or by any of the other Security  Documents has been discharged in full
or  until  title to the  Property  has  passed  after  foreclosure  sale and all
applicable periods of redemption have expired.

         Section 15.10. Effect of Sale. Upon the completion of any sale or sales
made by Trustee under or by virtue of this Deed of Trust,  Trustee shall execute
and deliver to the accepted  purchaser or purchasers a good and sufficient  deed
or deeds,  conveying,  assigning and transferring the Property,  but without any
covenant  or  warranty,  express or  implied.  The  recitals in such deed of any
matters or facts shall be conclusive  proof of the truthfulness  thereof.  After
the expiration of any appropriate statutory period of redemption,  any such sale
or sales  made under or by virtue of this Deed of Trust  whether  made under the
power of sale herein granted or under or by virtue of judicial proceedings or of
a judgment or decree of  foreclosure  and sale,  shall operate to divest all the
estate, right, title, interest,  claim and demand whatsoever,  whether at law or
in equity,  of Grantor in and to the properties and rights so sold, and shall be
a perpetual  bar both at law and in equity  against  Grantor and against any and
all persons claiming or who may claim the same or any part thereof from, through
or under Grantor.

         Section  15.11.  Waiver and Release.  Grantor  hereby  irrevocably  and
unconditionally  waives and  releases,  to the extent  permitted by law: (a) all
benefits  that might  accrue to  Grantor by virtue of any  present or future law
exempting the Property from  attachment,  levy or sale on execution or providing
for any appraisement,  valuation, stay of execution,  redemption, exemption from
civil

process  or  extension  of time for  payment;  (b) all  notices  of any Event of
Default or of  Trustee's  exercise of any right,  remedy,  or recourse  provided
under the Security Documents;  and (c) any right to a marshalling of assets or a
sale in inverse order of alienation.

         Section 15.12.  Acquisition of Property by  Beneficiary.  Upon any sale
made under or by virtue of this Deed of Trust,  whether  made under the power of
sale  herein  granted  or under or by virtue  of  judicial  proceedings  or of a
judgment or decree of foreclosure and sale,  Beneficiary may bid for and acquire
the  Property or any part  thereof and in lieu of paying cash  therefor may make
settlement for the purchase price by crediting upon the indebtedness  secured by
this Deed of Trust the net sales price after deducting therefrom the expenses of
the sale and the cost of the  action and any other  sums  which  Beneficiary  is
authorized to deduct under this Deed of Trust. Beneficiary upon so acquiring the
Property, or any part thereof,  shall be entitled to hold, lease, rent, operate,
manage and sell the same in any manner provided by applicable laws.

court of competent  jurisdiction  for aid and  direction in the execution of the
trusts  hereunder  and the  enforcement  of the  rights and  remedies  available
hereunder,  and Trustee or Beneficiary may obtain orders or decrees directing or
confirming or approving acts in the execution of such trusts and the enforcement

sale or any action or  proceeding  unless held or commenced  and  maintained  by
Trustee  under  this Deed of Trust.  Grantor  shall  pay to  Trustee  reasonable
compensation and  reimbursement  for services and expenses in the enforcement of
the trusts created  hereunder,  including  reasonable  attorneys' fees.  Grantor
shall indemnify Trustee and Beneficiary against all losses,  claims, demands and

hereunder or by law.

         Section 17.4.  Marshalling of Assets.  Grantor on its own behalf and on
behalf of its  successors  and  assigns  hereby  expressly  waives all rights to
require a marshalling of assets by Trustee or Beneficiary or to require  Trustee
or  Beneficiary to first resort to the sale of any portion of the Property which
might have been  retained  by Grantor  before  foreclosing  upon and selling any
other portion as may be conveyed by Grantor subject to this Deed of Trust.

         Section 17.5.  Partial Release.  Without affecting the liability of any
other person for the payment of any  indebtedness  herein  mentioned  (including
Grantor  should it convey  such  Property)  and  without  affecting  the lien or
priority hereof upon any property not released, Beneficiary may, without notice,
release  any person so liable,  extend the  maturity  or modify the terms of any
such obligation, or grant other indulgences,  release or reconvey or cause to be
released  or  reconveyed  at any time all or any part of the  Property,  take or
release  any other  security or make  compositions  or other  arrangements  with
debtors.  Beneficiary may also accept additional  security,  either concurrently
herewith or hereafter,  and sell the same or otherwise  realize  thereon  either
before, concurrently with, or after sale hereunder.

         Section  17.6.  Beneficiary's  Consent.  Except as otherwise  expressly
provided  herein,  in any instance  hereunder  where  Beneficiary's  approval or
consent is required or the exercise of Beneficiary's  judgment is required,  the

due date or late performance of any obligation secured hereby, Beneficiary shall
not waive  its  right  against  any  person  obligated  directly  or  indirectly
hereunder or on any indebtedness hereby secured either to require prompt payment
when due of all other sums so secured or to declare  default for failure to make
such  prompt  payment.  No  exercise  of any  right  or  remedy  by  Trustee  or
Beneficiary  hereunder  shall  constitute  a waiver of any other right or remedy
herein contained or provided by law.

                  b. No delay or  omission  of  Trustee  or  Beneficiary  in the

failure of performance by Grantor of any covenant or agreement contained in this
Deed of Trust, the Note or the Security Documents.

         Section 17.8.   Paragraph Headings.  The headings of each paragraph are

provisions  contained  in this Deed of Trust or the  application  thereof to any
person or  circumstances  shall to any extent be held to be invalid,  illegal or

shall not affect any other provision of this Deed of Trust, but the remainder of
this Deed of Trust or the  application of such term to persons or  circumstances

be affected  thereby and shall be valid and  enforceable  to the fullest  extent
permitted by law.

         Section 17.10.  Successors-in-Interest.  This Deed of Trust applies to,

and owner,  including pledgees, of the Note, whether or not named as Beneficiary
herein.

         Section  17.11.  Modifications.  This Deed of Trust may not be amended,

hereby; however,  nothing contained herein shall in any way obligate Beneficiary
to make any such future advances as mentioned herein.

sole  discretion  of  Beneficiary,  (c) may be  exercised  as often as  occasion
