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

                                  June 30, 2001

Note 1 - Basis of Presentation

     The accompanying unaudited condensed consolidated financial statements of
St. Mary Land & Exploration Company and Subsidiaries ("St. Mary" or the
"Company") have been prepared in accordance with accounting principles generally
accepted in the United States for interim financial information. They do not
include all information and notes required by generally accepted accounting
principles for complete financial statements. However, except as disclosed
herein, there has been no material change in the information disclosed in the
notes to consolidated financial statements included in St. Mary's Annual Report
on Form 10-K for the year ended December 31, 2000. In the opinion of Management,
all adjustments (consisting of normal recurring accruals) considered necessary
for a fair presentation have been included. Operating results for the periods
presented are not necessarily indicative of the results that may be expected for
the full year.

     The accounting policies followed by the Company are set forth in Note 1 to
the Company's consolidated financial statements in the Form 10-K for the year
ended December 31, 2000. It is suggested that these unaudited condensed
consolidated financial statements be read in conjunction with the consolidated
financial statements and notes included in the Form 10-K.

Note 2 - Capital Stock

     In July 2000 St. Mary's board of directors approved a two-for-one stock
split effected in the form of a stock dividend whereby one additional common
share of stock was distributed for each common share outstanding. The stock
split was distributed on September 5, 2000, to shareholders of record as of the
close of business on August 21, 2000. All share and per share amounts for all
periods presented herein have been restated to reflect this stock split.

     In August 1998 the Company's board of directors approved a stock repurchase
program whereby the Company may purchase from time to time, in open market
purchases or negotiated sales, up to two million shares of its common stock.
During the second quarter of 2001 the Company repurchased 434,000 shares of its
common stock under the program at a weighted average price of $20.67 per share,
bringing the total number of shares repurchased under the program to 909,900 at
a weighted average price of $15.49 per share. Additional purchases of shares by
the Company may occur as market conditions warrant. Such purchases would be
funded with internal cash flows and borrowings under the Company's credit
facility.

     In April 2001 the Company sold 100,000 put options on its own common stock
for $99,000 in cash. These put options gave the holder the right to require the
Company to purchase up to 100,000 shares of its own common stock from the holder
at $20.22 per share on July 11, 2001. These options expired unexercised. In June
2001 the Company sold 100,000 put options on its own common stock for $94,000 in
cash. These put options give the holder the right to require the Company to
purchase up to 100,000 shares of its own common stock from the holder at $19.22
per share on September 24, 2001.

                                      -8-

Note 3 - Income Taxes

     Federal income tax expense for the three and six months ended June 30, 2001
and 2000 differ from the amounts that would be provided by applying the
statutory U.S. Federal income tax rate to income before income taxes primarily
due to Section 29 credits, percentage depletion, and the effect of state income
taxes. During 2000 the Company utilized its net operating loss carryover and
resulting deferred tax asset from 1999. At June 30, 2001 the Company's current
portion of income tax expense was $9,361,000. Accounts payable and accrued
expenses includes income tax payable of $137,000 at June 2001.

Note 4 - Long-term Debt

     On April 30, 2001 St. Mary entered into an agreement to amend the
existing long-term revolving credit agreement. The maximum loan amount remains
at $200.0 million. The lender may periodically re-determine the aggregate
borrowing base depending upon the value of St. Mary's oil and gas properties and
other assets. The amendment increases the borrowing base by $30.0 million to
$170.0 million. The accepted borrowing base was $40.0 million at June 30, 2001.
The credit agreement has a maturity date of December 31, 2006, and includes a
revolving period that matures on June 30, 2003. The amended agreement deletes
all references to and provisions of the short-term tranche previously available
to St. Mary. The Company must comply with certain covenants including
maintenance of stockholders' equity at a specified level and limitations on
additional indebtedness. The Company had $13,400,000 in outstanding borrowings
under its revolving credit agreement as of June 30, 2001, and the weighted
average interest rate paid for the six months ended June 30, 2001 was 9.0%
including commitment fees paid on the unused portion of the borrowing base. The
Company's debt to total capitalization ratio as defined under the agreement was
4.7% as of June 30, 2001.


Note 5 - Financial Instruments

     On January 1, 2001 the Company adopted Statement of Financial Accounting
Standards ("SFAS") No. 133, "Accounting for Derivative Instruments and Hedging
Activities." The adoption of SFAS No. 133 resulted in the Company recording a
liability of $45,699,000 for the fair value of the derivative instruments at
January 1, 2001. The Company's adoption entry resulted in deferral of the
recognition of this liability to accumulated other comprehensive loss of
$28,587,000 at January 1, 2001. During the first six months of 2001 the Company
recognized no additional hedge loss from hedge ineffectiveness on derivative
instruments that were designated and qualified as cash flow hedging instruments.
The Company anticipates that all hedge transactions will occur as expected.
Based on current prices we anticipate that $1.6 million of the after tax loss
amount included in accumulated and other comprehensive income will be included
in earnings during the next 12 months.

     The Company seeks to protect its rate of return on acquisitions of
producing properties by hedging cash flow when the economic criteria from its
evaluation and pricing model indicate it would be appropriate. Management's
strategy is to hedge cash flows from investments requiring a gas price in excess
of $3.25 per Mcf and an oil price in excess of $22.50 per Bbl in order to meet
minimum rate-of-return criteria. The Company anticipates this strategy will
result in the hedging of future cash flow from acquisitions. St. Mary generally
limits its aggregate hedge position to no more than 35% of its total production
but will hedge up to 50% of total production in certain circumstances. The
Company seeks to minimize basis risk and index the majority of oil hedges to
NYMEX prices and the majority of gas hedges to various regional index prices
associated with pipelines in proximity to its areas of gas production.

Note 6 - Newly Issued Accounting Standards

     In June 2001 the Financial Accounting Standards Board ("FASB") issued SFAS
No. 141, "Business Combinations." Under this statement all business combinations
must be accounted for under the purchase method. The pooling method is no longer
allowed. The statement also establishes criteria to assess when to recognize
intangible assets separately from goodwill. SFAS No. 141 is effective for
business combinations initiated after June 30, 2001 and for all business
combinations using the purchase method for which the date of acquisition is
after June 30, 2001. At this time the Company has no pending business
combinations that would be affected by the adoption of this statement.

                                      -9-

     In June 2001 the FASB issued SFAS No. 142, "Goodwill and Other Intangible
Assets." This statement addresses the accounting for goodwill and other
intangible assets and provides specific guidance for testing goodwill and other
intangible assets for impairment. This statement is effective for fiscal years
beginning after December 15, 2001. The Company does not anticipate that the
adoption of this statement will have a material effect on the Company's
financial position or results of operations.

     In July 2001 the FASB issued SFAS No. 143, "Accounting for Asset Retirement
Obligations." This statement requires companies to recognize the fair value of
an asset retirement liability in the financial statements by capitalizing that
cost as part of the cost of the related long-lived asset. The asset retirement
liability should then be allocated to expense by using a systematic and rational
method. The statement is effective for fiscal years beginning after June 15,
2002. The Company has not yet determined the impact of adoption of this
statement.

                                      -10-

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

     This Quarterly Report on Form 10-Q includes certain statements that may be
deemed to be "forward-looking statements" within the meaning of Section 27A of
the Securities Act of 1933 and Section 21E of the Securities Exchange Act of
1934. All statements, other than statements of historical facts, included in
this Form 10-Q that address activities, events or developments that St. Mary
management forecasts, expects, believes or anticipates will or may occur in the
future are forward-looking statements. Examples of forward-looking statements
may include discussion of such matters as:

o    forecasted production, lease operating expenses, transportation costs,
     DD&A, general and administrative expenses, and current income taxes for
     future periods,
o    the amount and nature of future capital, development and exploration
     expenditures,
o    the drilling of wells,
o    reserve estimates and the estimates of both future net revenues and the
     present value of future net revenues that are included in their
     calculation,
o    future oil and gas production estimates,
o    repayment of debt,
o    business strategies,
o    expansion and growth of operations, and
o    other similar matters.

     These statements are based on certain assumptions and analyses made by us
in light of our experience and our perception of historical trends, current
conditions, expected future developments and other factors we believe are
appropriate in the circumstances. Such statements are subject to a number of
assumptions, risks and uncertainties, including such factors as the volatility
and level of oil and natural gas prices, uncertainties in cash flow, expected
acquisition benefits, production rates and reserve replacement, reserve
estimates, drilling and operating risks, competition, litigation, environmental
matters, the potential impact of government regulations, and other matters such
as those discussed in the "Risk Factors" section of St. Mary's 2000 Annual
Report on Form 10-K, many of which are beyond our control. Readers are cautioned
that forward-looking statements are not guarantees of future performance and
that actual results or developments may differ materially from those expressed
or implied in the forward-looking statements.

Three-Month Comparison

     Oil and Gas Production Revenues. St. Mary's quarterly oil and gas
production revenues increased $11.6 million, or 26% to $55.4 million for the
three months ended June 30, 2001, compared with $43.8 million for the same
period in 2000. The increase was the result of an oil production volume increase
of 4%, a gas production increase of 5% and increases in the average price
received for both oil and gas in the second quarter of 2001 compared to 2000.
The average realized gas price increased 25% to $4.08 per Mcf, while the average
realized oil price increased 9% to $24.30 per Bbl. Average net daily production
increased to 149.6 MMCFE for 2001 compared with 142.6 MMCFE in 2000. Our
December 2000 acquisition of JN Exploration et al properties added $3.5 million
of revenue and average net daily production of 8.2 MMCFE to the second quarter
of 2001.

                                      -12-

     St. Mary hedged approximately 32% or 190 MBbls of its oil production for
the three months ended June 30, 2001, and realized a $775,000 decrease in oil
revenue attributable to hedging compared with a $3.2 million decrease in 2000.
Without these contracts we would have received an average price of $25.60 per
Bbl in the second quarter of 2001 compared to $27.83 per Bbl in 2000. St. Mary
also hedged 42% of its 2001 second quarter gas production or 4.6 million MMBtu
and realized a $5.1 million decrease in gas revenue compared with a $3.2 million
decrease in gas revenue in 2000. Without these contracts we would have received
an average price of $4.51 per Mcf for the three months ended June 30, 2001,
compared to $3.84 per Mcf for the same period in 2000.

     Gain on sale of proved properties. Gain on sale of proved properties
decreased $2.3 million for the quarter ended June 30, 2001 compared to the same
period in 2000. There have been no significant sales of proved properties in
2001.

     Oil and Gas Production Costs. Oil and gas production costs consist of lease
operating expense, production taxes and transportation expenses. Total
production costs increased $4.8 million or 56% to $13.4 million for the three
months ended June 30, 2001, from $8.6 million in 2000. In the second quarter of
2001 we experienced a $1.5 million increase in non-recurring LOE as we took
advantage of workover rig availability. Williston basin acquisitions in the last
half of 2000 added an additional $600,000 of LOE to 2001. Our JN Exploration et
al acquisition properties represented $566,000 of the total increase. We have
also experienced higher recurring LOE costs in the Williston basin, the Permian
basin and the Gulf Coast/GOM as a result of increased competition for limited
availability of services. In addition, higher production taxes and
transportation expenses resulting from higher oil and gas revenues account for
the remaining 12% of the increase. Total oil and gas production costs per MCFE
increased 50% to $0.99 for the six months ended June 30, 2001 compared with
$0.66 for 2000. An $0.11 per MCFE increase was due to the increase in
non-recurring LOE. A $0.09 per MCFE increase was due to the acquisitions
previously discussed. Another $0.04 per MCFE increase was due to increased
production taxes and transportation expenses.

     Depreciation, Depletion, Amortization and Impairment. Depreciation,
depletion and amortization expense ("DD&A") increased $4.6 million or 55% to
$12.9 million for the three months ended June 30, 2001, from $8.3 million in
2000. DD&A per MCFE increased by 48% to $0.95 for the second quarter of 2001
compared with $0.64 in 2000. This increase reflects acquisitions and drilling
results in 2000 and 2001 that have added costs at a higher per-unit rate. The
unit rate was further affected by downward adjustments to reserves due to
pricing adjustments at June 30, 2001.

     St. Mary reviews its producing properties for impairments when events or
changes in circumstances indicate that an impairment in value 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 future net revenues for the producing property discounted at
15%. Future net revenues are estimated using prices based on NYMEX strip that
are then escalated for each of the next 5 years and include the estimated
effects of hedging contracts in place at December 31, 2000. We recorded a
$73,000 impairment of proved oil and gas properties in the second quarter of
2001 compared with $863,000 in 2000.

     Abandonment and impairment of unproved properties was $608,000 for the
three months ended June 30, 2001, compared with $609,000 in 2000.

                                      -13-

     Exploration. Exploration expense increased $491,000 or 30% to $2.1 million
for the three months ended June 30, 2001, compared with $1.7 million in 2000.
The increase resulted from an increase in personnel costs associated with
exploration activity.

     General and Administrative. General and administrative expenses increased
$1.2 million or 52% to $3.5 million for the three months ended June 30, 2001,
compared with $2.3 million in 2000. Increases in compensation expense associated
with increased personnel, our incentive plans and general cost inflation were
partially offset by a $247,000 increase in COPAS overhead reimbursement from
operations.

     Income Taxes. Income tax expense totaled $8.9 million for the three months
ended June 30, 2001, and $9.4 million in 2000, resulting in effective tax rates
of 38.4% and 39.1%, respectively.

     Net Income. Net income for the three months ended June 30, 2001 decreased
$363,000 to $14.2 million compared with $14.6 million in 2000. A 25% increase in
gas prices and a 9% increase in oil prices combined with a 4% increase in oil
production and a 5% increase in gas production resulted in an $11.6 million
increase in oil and gas production revenue. This increase was offset by a $4.8
million increase in oil and gas production costs, a $4.6 million increase in
DD&A as well as a $1.2 million increase in general and administrative
expense. Net income for the three months ended June 30, 2000 also included a
$2.3 million pre-tax nonrecurring gain on the sale of proved property.

Six-Month Comparison

     Oil and Gas Production Revenues. St. Mary experienced an increase in oil
and gas production revenues of $42.5 million, or 53% to $123.3 million for the
six months ended June 30, 2001, compared with $80.8 million for the same period
in 2000. The increase was the result of an oil production volume increase of 8%,
a gas production increase of 5% and increases in the average price received for
both oil and gas in the first six months of 2001 compared to 2000. The average
realized gas price increased 62% to $4.75 per Mcf, while the average realized
oil price increased 8% to $24.92 per Bbl. Average net daily production increased
to 148.4 MMCFE for the first six months of 2001 compared with 139.9 MMCFE in
2000. Our December 2000 acquisition of JN Exploration et al properties added
$8.4 million of revenue and average net daily production of 8.0 MMCFE for the
six months ended June 30, 2001.

     St. Mary hedged approximately 32% or 384 MBbls of its oil production for
the six months ended June 30, 2001, and realized a $1.9 million decrease in oil
revenue attributable to hedging compared with a $5.3 million decrease in 2000.
Without these contracts we would have received an average price of $26.48 per
Bbl for the six months ended June 30, 2001 compared to $27.90 per Bbl in 2000.
St. Mary also hedged 43% of its gas production or 9.2 million MMBtu and realized
a $20.4 million decrease in gas revenue for the six months ended June 30, 2001
compared with a $3.2 million decrease in gas revenue in 2000. Without these
contracts we would have received an average price of $5.79 per Mcf for the six
months ended June 30, 2001, compared to $3.04 per Mcf for the same period in
2000.

     Gain on sale of proved properties. Gain on sale of proved properties
decreased $2.3 million for the six months ended June 30, 2001 compared to the
same period in 2000. There have been no significant sales of proved properties
in 2001.

     Oil and Gas Production Costs. Oil and gas production costs consist of lease
operating expense, production taxes and transportation expenses. Total
production costs increased $8.4 million or 50% to $25.5 million for the six
months ended June 30, 2001, from $17.0 million in 2000. In the first six months
of 2001 we experienced a $1.3 million increase in non-recurring LOE as we took
advantage of workover rig availability. Williston basin acquisitions in the last
half of 2000 added an additional $1.3 million of LOE to 2001. Our JN Exploration
et al acquisition properties represented $1.2 million of the total increase. We
have also experienced higher recurring LOE costs in the Williston basin, the
Permian basin and the Gulf Coast/GOM as a result of increased competition for
limited availability of services. In addition, higher production taxes and
transportation expenses resulting from higher oil and gas revenues account for
the remaining 31% of the increase. Total oil and gas production costs per MCFE
increased 42% to $0.95 for the six months ended June 30, 2001 compared with
$0.67 for 2000. A $0.09 per MCFE increase was due to the acquisitions previously
discussed. Another $0.09 per MCFE increase was due to increased production taxes
and transportation expenses. A $0.05 per MCFE increase was due to the increase
in non-recurring LOE.

                                      -14-

     Depreciation, Depletion, Amortization and Impairment. DD&A increased
$7.0 million or 41% to $24.2 million for the six months ended June 30, 2001,
from $17.2 million in 2000. DD&A per MCFE increased by 33% to $0.90 for the
six months ended June 30, 2001 compared with $.67 in 2000. This increase
reflects acquisitions and drilling results in 2000 and 2001 that added costs at
a higher per unit rate. The unit rate was further affected by downward
adjustments to reserves due to pricing adjustments at June 30, 2001.

     St. Mary reviews its producing properties for impairments when events or
changes in circumstances indicate that an impairment in value 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 future net revenues for the producing property discounted at
15%. Future net revenues are estimated using prices based on NYMEX strip that
are then escalated for each of the next 5 years and include the estimated
effects of hedging contracts in place at December 31, 2000. We recorded a
$244,000 impairment of proved oil and gas properties for the six months ended
June 30, 2001 compared with $2.0 million in 2000.

     Abandonment and impairment of unproved properties were $1.1 million for the
six months ended June 30, 2001, compared with $1.3 million in 2000.

     Exploration. Exploration expense increased $6.1 million or 139% to $10.5
million for the six months ended June 30, 2001, compared with $4.4 million in
2000. The increase resulted from a $3.6 million increase in exploratory dry
holes, an $875,000 increase in geological and geophysical expense and an
increase in personnel costs associated with exploration activity of $1.6
million.

     General and Administrative. General and administrative expenses increased
$2.5 million or 48% to $7.6 million for the six months ended June 30, 2001,
compared with $5.1 million in 2000. Increases in compensation expense associated
with increased personnel, our incentive plans and general cost inflation were
partially offset by a $557,000 increase in COPAS overhead reimbursement from
operations.

     Income Taxes. Income tax expense totaled $20.4 million for the six months
ended June 30, 2001, and $13.8 million in 2000, resulting in effective tax rates
of 37.0% and 38.1%, respectively.

     Net Income. Net income for the six months ended June 30, 2001 increased
$12.1 million or 54% to $34.6 million compared with $22.5 million in 2000. A 62%
increase in gas prices and an 8% increase in oil prices combined with an 8%
increase in oil production and a 5% increase in gas production resulted in a
$42.5 million increase in oil and gas production revenue. This increase was
offset by corresponding increases in oil and gas production costs and DD&A
as well as a $6.1 million increase in exploration expense, a $2.5 million
increase in general and administrative expense and a $6.5 million increase in
income tax expense. A re-tax gain on the sale of proved properties of $2.3
million in 2000 was partially offset by decreases in proved and unproved
property impairments.

Liquidity and Capital Resources

     St. Mary'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. Our 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. Exploration and development programs
are generally financed from internally generated cash flow, bank debt and cash
and cash equivalents on hand. The capital expenditure budget is continually
reviewed based on changes in cash flow and other factors.

                                      -15-

     Cash Flow. St. Mary's net cash provided by operating activities increased
$50.3 million or 223% to $72.9 million for the six months ended June 30, 2001
compared with $22.5 million in 2000. The increase reflects the effect of the
increase in oil and gas production revenues, a general increase in non-cash
expenses and an increase in accounts payable for the period ended June 30, 2001
that are offset by an increase in accounts receivable for the period ended June
30, 2000.

     Exploratory dry hole costs are included in cash flows from investing
activities even though these costs are expensed as incurred. If exploratory dry
hole costs had been included in operating cash flows, the net cash provided by
operating activities would have been $62.4 million and $18.2 million in the
first six months of 2001 and 2000, respectively.

     Net cash used in investing activities increased $17.7 million or 49% to
$54.0 million for the six months ended June 30, 2001, compared with $36.3
million in 2000. This increase is due to increased capital expenditures and a
decrease in proceeds from the sale of oil and gas properties that are partially
offset by the receipt of $7.0 million of proceeds from the December 2000 sale of
KMOC stock. Total capital expenditures, including acquisitions of oil and gas
properties, in the first six months of 2001 increased $22.7 million or 58% to
$61.7 million compared with $39.0 million in the first half of 2000.

     If exploratory dry hole costs had been included in operating cash flows
rather than in investing cash flows, net cash used in investing activities would
have been $43.5 million and $32.0 million in the first six months of 2001 and
2000, respectively.

     Net cash used in financing activities increased $21.7 million to $19.2
million for the six months ended June 30, 2001, compared with net cash provided
by financing activities of $2.5 million in 2000. St. Mary made net repayments of
$8.6 million of debt in 2001 compared to an $850,000 debt increase in 2000.
Additionally, we repurchased $10.6 million more of our own common stock and
received $1.6 million less in proceeds from the sale of our common stock during
the first two quarters of 2001 compared to 2000. All sales of our common stock
resulted from stock option exercises and sales under St. Mary's employee stock
purchase plan.

     St. Mary had $6.2 million in cash and cash equivalents and had working
capital of $33.1 million as of June 30, 2001, compared with $6.6 million in cash
and cash equivalents and working capital of $40.6 million at December 31, 2000.
The small change in cash and cash equivalents reflects that our cash provided by
operations was sufficient to cover our increased capital expenditures, our debt
repayment and our repurchase of St. Mary's common stock during the first six
months of 2001.

     Credit Facility. On April 30, 2001 St. Mary entered into an agreement to
amend the existing long-term revolving credit agreement. The maximum loan amount
remains at $200.0 million. The lender may periodically re-determine the
aggregate borrowing base depending upon the value of St. Mary's oil and gas
properties and other assets. The amendment increases the borrowing base by $30.0
million to $170.0 million. The accepted borrowing base was $40.0 million at June
30, 2001. The credit agreement has a maturity date of December 31, 2006, and
includes a revolving period that matures on June 30, 2003. The amended agreement
deletes all references to and provisions of the short-term tranche previously
available to St. Mary. We must comply with certain covenants including
maintenance of stockholders' equity at a specified level and limitations on
additional indebtedness. As of June 30, 2001 and December 31, 2000, $13.4
million and $22.0 million, respectively, was outstanding under this credit
agreement. These outstanding balances accrue interest at rates determined by St
Mary's debt to total capitalization ratio. During the revolving period of the
loan, loan balances accrue interest at our option of either (1) the higher of
the federal funds rate plus 1/2% or the prime rate, or (2) LIBOR plus 3/4% when
our debt to total capitalization is less than 30%, up to a maximum of either (a)
the higher of the federal funds rate plus 3/4% or the prime rate plus 1/4%, or
(b) LIBOR plus 1-3/8% when our debt to total capitalization is equal to or
greater than 50%. The debt to total capitalization ratio as defined under the
agreement was 4.7% as of June 30, 2001.

                                      -16-

     Common Stock. At the annual shareholder meeting on May 23, 2001 the
shareholders of St. Mary voted to increase the amount of authorized common
shares to 100,000,000.

     In July 2000 St. Mary's board of directors approved a two-for-one stock
split effected in the form of a stock dividend whereby one additional common
share of stock was distributed for each common share outstanding. The stock
split was distributed on September 5, 2000, to shareholders of record as of the
close of business on August 21, 2000. All share and per share amounts for all
periods presented herein have been restated to reflect this stock split.

     In August 1998 St. Mary's board of directors authorized a stock repurchase
program whereby we may purchase from time-to-time, in open market transactions
or negotiated sales, up to two million of our common shares. Through December
31, 2000 we had repurchased a total of 395,600 shares of St. Mary's common
stock under the program for $3.3 million at a weighted average price of $8.44
per share. To date in 2001 we have repurchased an additional 514,300 shares for
a weighted average price of $20.91 per share. We anticipate that additional
purchases of shares may occur as market conditions warrant. As part of this
program we sold put options in April 2001 whereby the holder had the right to
require St. Mary to purchase up to 100,000 shares of St. Mary's common stock
from the holder at $20.22 per share on July 11, 2001. We received a $99,000
premium from this sale. These options expired unexercised. In June 2001 we sold
additional put options whereby we could be required to purchase up to 100,000
shares of our common stock from the holder at $19.22 per share on September 24,
2001. We received a $94,000 premium from this sale. Any future purchases will be
funded with internal cash flow and borrowings under St. Mary's credit facility.

     Capital and Exploration Expenditures Incurred. St. Mary'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 St. Mary in its oil and gas
activities during the periods indicated.

                                                    ========    ========

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

     St. Mary's total costs incurred in the first six months of 2001 increased
$29.5 million or 76% compared to the first six months of 2000. Unproved property
acquisitions increased by $8.2 million as a result of an increase in general
leasing activity and our acquisition of leases in the Hanging Woman Basin of
Montana and Wyoming for coalbed methane development. We spent $68.2 million in
the first six months of 2001 for unproved property acquisitions and domestic
exploration and development compared to $28.2 million for the comparable period
in 2000. This increase is primarily the result of increased drilling activity.

                                      -17-

     Outlook. Management believes that St Mary's existing capital resources,
cash flows from operations and available borrowings are sufficient to meet its
anticipated capital and operating requirements for the remainder of 2001.

     We now anticipate spending approximately $160.0 million for capital and
exploration expenditures in 2001 with $130.0 million allocated for ongoing
exploration and development and $30.0 million for acquisitions of producing
properties. Anticipated ongoing exploration and development expenditures for
each of St. Mary's core areas is as follows:


o    Mid-Continent region                             $ 46.0 million
o    Gulf Coast and Gulf of Mexico region             $ 38.0 million
o    ArkLaTex region                                  $ 14.0 million
o    Williston Basin                                  $ 26.0 million
o    Permian Basin and other                          $  6.0 million

     The amount not funded from our internally generated cash flow in 2001 can
be funded from our credit facility. The amount and allocation of future capital
and exploration expenditures will depend upon a number of factors including the
number and size of available acquisition opportunities and our ability to
assimilate these acquisitions. Also, the impact of oil and gas prices on
investment opportunities, the availability of capital and borrowing capability
and the success of our development and exploratory activity could lead to
funding requirements for further development.

     Natural gas prices continue to decline, but still remain at a high level of
approximately $3.00 per MMBTU while oil prices remain good. Our production base
and balance sheet are strong. We are seeing rig and service availability ease
and costs flattening, and in some cases declining modestly. However, the
acquisition market for properties remains overheated. We remain disciplined and
patient and have reduced our forecast of added production from acquisitions from
2.6 BCFE to 0.5 BCFE. We are currently forecasting the following information for
St. Mary for 2001:

o    Production                                         55-57 BCFE
o    Lease operating expense, including
     production taxes and transportation                $0.85-0.95/MCFE
o    Depreciation, depletion and amortization           $0.95-1.00/MCFE
o    General and administrative expense                 $0.26-0.30/MCFE
o    Current income taxes paid are expected
     to approximate between 20% and 25% of
     total tax expense and will depend
     upon prices we receive and actual
     expenditures for intangible drilling costs
o    Discretionary cash flows-a common industry
     financial measure computed as net income
     using a NYMEX gas price of $4.70 and a NYMEX
     oil price of $27.40 plus depreciation,
     depletion, amortization, impairments,
     deferred taxes and exploration expense             $5.00-$5.50/common share

     St. Mary seeks to protect its rate of return on acquisitions of producing
properties by hedging cash flow when the economic criteria from its evaluation
and pricing model indicate it would be appropriate. Management's strategy is to
hedge cash flows from investments requiring a gas price in excess of $3.25 per
Mcf and an oil price in excess of $22.50 per Bbl in order to meet minimum
rate-of-return criteria. We anticipate this strategy will result in the hedging
of future cash flow from acquisitions. We generally limit St. Mary's aggregate
hedge position to no more than 35% of total production but will hedge up to 50%
of total production in certain circumstances. We seek to minimize basis risk and
index the majority of oil hedges to NYMEX prices and the majority of gas hedges
to various regional index prices associated with pipelines in proximity to St.
Mary's areas of gas production. Please see the discussion in Accounting Matters
below. Including hedges entered into since June 30, 2001 we have hedged as
follows:

     If all these commodity hedging contracts had closed on June 30, 2001 St.
Mary would have been required to pay approximately $2.0 million based on
quarter-end pricing. As of that date we had no margin deposits outstanding to
counterparties.

     On June 30, 2001 St. Mary owned shares of KMOC stock that Management
believes has a current market value in excess of its carrying value.

Accounting Matters

     On January 1, 2001 we adopted Statement of Financial Accounting Standards
("SFAS") No. 133, "Accounting for Derivative Instruments and Hedging
Activities." The adoption of SFAS No. 133 resulted in St. Mary recording a
liability of $45.7 million for the fair value of the derivative instruments at
January 1, 2001. The adoption entry resulted in deferral of the recognition of
this liability to accumulated other comprehensive loss of $28.6 million at
January 1, 2001. During the first six months of 2001 we recognized no additional
hedge gain or loss from hedge ineffectiveness on derivative instruments that
were designated and qualified as cash flow hedging instruments. We anticipate
that all hedge transactions will occur as expected. Based on current prices we
anticipate that $1.6 million of the after tax loss amount included in
accumulated and other comprehensive income will be included in earnings during
the next 12 months.

                                      -19-

     In June 2001 the Financial Accounting Standards Board ("FASB") issued SFAS
No. 141, "Business Combinations." Under this statement all business combinations
must be accounted for under the purchase method. The pooling method is no longer
allowed. The statement also establishes criteria to assess when to recognize
intangible assets separately from goodwill. SFAS No. 141 is effective for
business combinations initiated after June 30, 2001 and for all business
combinations using the purchase method for which the date of acquisition is
after June 30, 2001. At this time we have no pending business combinations that
would be affected by the adoption of this statement.

     In June 2001 the FASB issued SFAS No. 142, "Goodwill and Other Intangible
Assets." This statement addresses the accounting for goodwill and other
intangible assets and provides specific guidance for testing goodwill and other
intangible assets for impairment. This statement is effective for fiscal years
beginning after December 15, 2001. We do not anticipate that the adoption of
this statement will have a material effect on our financial position or results
of operations.

     In July 2001 the FASB issued SFAS No. 143, "Accounting for Asset Retirement
Obligations." This statement requires companies to recognize the fair value of
an asset retirement liability in the financial statements by capitalizing that
cost as part of the cost of the related long-lived asset. The asset retirement
liability should then be allocated to expense by using a systematic and rational
method. The statement is effective for fiscal years beginning after June 15,
2002. St. Mary has not yet determined the impact of adoption of this statement.

ITEM 3.  QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

     St. Mary 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 us. In prior years we have occasionally hedged interest rates, and may
do so in the future should circumstances warrant.

     Our board of directors has adopted a policy regarding the use of derivative
instruments. This policy requires every derivative used by St. Mary 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 board
of directors periodically reviews these programs.

     Commodity Price Risk. St. Mary uses various hedging arrangements to manage
its 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 we will receive for the
volumes to which the hedge relates. Consequently, while these hedging
arrangements are structured to reduce our exposure to decreases in prices
associated with the hedged commodity, they also limit the benefit we might
otherwise receive from any price increases associated with the hedged commodity.
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 quarter-end. The fair values of the futures are
based on quoted market prices obtained from the New York Mercantile Exchange.

     A hypothetical $0.10 per MMBtu change in St. Mary's quarter-end market
prices for natural gas swaps and futures contracts on a notional amount of 10.0
million MMBtu would cause a potential $419,000 change in net income before
income taxes for contracts in place on June 30, 2001. A hypothetical $1.00 per
Bbl change in our quarter-end market prices for crude oil swaps and future
contracts on a notional amount of 423 MBbls would cause a potential $305,000
change in net income before income taxes for oil contracts in place on June 30,
2001. These hypothetical changes were discounted to present value using a 7.5%
discount rate since the latest expected maturity date of certain swaps and
futures contracts is greater than one year from the reporting date.

                                      -20-

     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. A sensitivity analysis presents the
hypothetical change in fair value of those financial instruments held by St.
Mary at June 30, 2001, 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 our floating rate debt approximates its
fair value. At June 30, 2001, we had floating rate debt of $13.4 million and had
no fixed rate debt. Assuming constant debt levels, the impact on results of
operations and cash flows for the remainder of the year resulting from a
one-percentage-point change in interest rates would be approximately $67,000
before taxes.

PART II.  OTHER INFORMATION

ITEM 2.  Changes in Securities and Use of Proceeds
         -----------------------------------------
         (c) In April 2001 St. Mary sold to a single purchaser 100,000 put
         options on its own common stock for $99,000 in cash. Those put options
         gave the holder the right to require St. Mary to purchase up to 100,000
         shares of its own common stock from the holder at $20.22 per share on
         July 11, 2001. Those options expired unexercised. In June 2001 St. Mary
         sold to a different single purchaser 100,000 put options on its own
         common stock for $94,000 in cash. These put options give the holder the
         right to require St. Mary to purchase up to 100,000 shares of its own
         common stock from the holder at $19.22 per share on September 24, 2001.
         The above securities were not registered under the Securities Act of
         1933 in reliance on the exemption from registration provided by Section
         4(2) of the Securities Act for transactions by an issuer not involving
         any public offering since the two purchasers are accredited investors
         and the option documents reflect the fact that the purchasers purchased
         the securities for their own account without a view to the distribution
         thereof.
