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

                           ---------------------------

                                  June 30, 2002

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, 2001. 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, 2001. 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.

         Certain amounts in the 2001 unaudited condensed consolidated financial
statements have been reclassified to correspond to the 2002 presentation.

Note 2 - Income Taxes

         Federal income tax expense for the three and six months ended June 30,
2002 and 2001 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, interest expense on convertible
debt with contingent interest provisions, and the effect of state income taxes.
For the six months ended June 30, 2002 the Company's current portion of income
tax expense was $1.5 million.

Note 3 - Long-term Debt

         In March 2002 the Company issued in a private placement a total of
$100,000,000 of 5.75% senior convertible notes due 2022 (the "Notes") with a
1/2% contingent interest provision (see Note 4). Interest payments will be made
on March 15 and September 15 of every year beginning September 15, 2002. The
Company received net proceeds of $96,754,000 after deducting the initial
purchasers' discount and offering expenses paid by the Company. The Notes are
general unsecured obligations and rank on a parity in right of payment with all
existing and future senior indebtedness and other general unsecured obligations.
They are senior in right of payment with all future subordinated indebtedness.
The Notes are convertible into the Company's common stock at a conversion price
of $26.00 per share, subject to adjustment. The Company can redeem the Notes
with cash in whole or in part at a repurchase price of 100% of the principal
amount plus accrued and unpaid interest (including contingent interest)
beginning on March 20, 2007. The note holders have the option of requiring the
Company to repurchase the Notes for cash at 100% of the principal amount plus
accrued and unpaid interest (including contingent interest) upon (1) a change in
control of St. Mary or (2) on March 20, 2007, March 15, 2012 and March 15, 2017.
If the note holders request repurchase on March 20, 2007, the Company may pay
the repurchase price with cash, shares of its common stock valued at a discount
to the market price at the time of repurchase or any combination of cash and its
discounted common stock. St. Mary is not restricted from paying dividends,

                                       8

incurring debt, or issuing or repurchasing its securities under the indenture
for the Notes. There are no financial covenants in the indenture. The Company
used a portion of the net proceeds from the Notes to repay its credit facility
balance and will use the remaining net proceeds to fund a portion of its 2002
capital budget. On March 25, 2002 the Company entered into a five-year
fixed-rate to floating-rate interest rate swap on $50,000,000 of Notes. The
floating rate for each applicable six-month period will be determined as LIBOR
plus 0.36%. For the initial six-month calculation period this rate was 2.69%.
See "Note 4 - Financial Instruments" for a discussion of the derivative
accounting for the interest rate swap.

         The stated total borrowing base under the Company's current long-term
revolving credit agreement was decreased to $160,000,000 in April 2002. Pursuant
to a March 4, 2002 amendment to the credit agreement, during the revolving
period of the loan, loan balances will accrue interest at the Company's option
of either (1) the higher of the federal funds rate plus 1/2% or the prime rate,
plus an additional 1/4% when the Company's debt to capitalization ratio is
greater than 50%, or (2) the LIBOR rate plus (a) 1% when the Company's debt to
total capitalization ratio is less than 30%, (b) 1 1/4% when the Company's debt
to capitalization ratio is greater than or equal to 30% but less than 40%, (c) 1
3/8% when the Company's debt to capitalization ratio is greater than or equal to
40% but less than 50%, or (d) 1 5/8% when the Company's debt to capitalization
ratio is greater than 50%. At June 30, 2002 the Company's debt to capitalization
ratio as defined under the credit agreement was 25.2%.

         The Company had no outstanding borrowings under its revolving credit
agreement and $100,000,000 in outstanding borrowings under the Notes as of June
30, 2002. The weighted average interest rate paid for the second quarter of 2002
was 4.6 % including commitment fees paid on the unused portion of the borrowing
base.

Note 4 - Financial Instruments

         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.

         On February 4, 2002 the Company entered into an agreement to monetize
its unrealized hedge gain receivable due from Enron for $1.1 million. This
amount was included in other comprehensive income at December 31, 2001, is
recorded in oil hedge gain and is reported in oil and gas production revenues in
the consolidated statements of operations. Amortization of $609,000 of other
comprehensive income related to commodity positions with Enron is also recorded
in oil hedge gain. Additional amortization will be recorded in oil hedge gain in
future months. Unrealized derivative loss on the consolidated statements of
operations includes $54,000 of net loss from oil and gas hedge ineffectiveness.

         The Notes contain a provision for payment of contingent interest if
certain conditions are met. Under Statement of Financial Accounting Standards
("SFAS") No. 133 this provision is considered an embedded equity-related
derivative that is not clearly and closely related to the fair value of an
equity interest and therefore must be separated from the Notes and accounted for
as a derivative instrument. The value of the derivative at issuance in March
2002 was $474,000. This amount was recorded as an adjustment to the Notes on the
consolidated balance sheets. Of this amount, $28,000 has been amortized through
interest expense. Unrealized derivative loss on the consolidated statements of
operations includes $245,000 of net loss from mark-to-market adjustments for
this derivative.

                                       9

         The fixed-rate to floating-rate interest rate swap on $50,000,000 of
Notes did not qualify for fair value hedge treatment under SFAS No. 133.
Unrealized derivative gain on the consolidated statements of operations includes
$2,244,000 of net gain from mark-to-market adjustments for this derivative
instrument.

         The Company anticipates that all oil and gas hedge transactions will
occur as expected. Based on current prices we anticipate that $3,228,000 of the
after tax gain amount included in accumulated and other comprehensive income
will be included in earnings during the next 12 months.

Note 6 - Newly Issued Accounting Standards

         In June 2002 the Financial Accounting Standards Board ("FASB") issued
SFAS No. 146, "Accounting for Costs Associated with Exit or Disposal
Activities." This statement addresses financial accounting and reporting for
costs associated with exit or disposal activities and nullifies EITF Issue No.
94-3, "Liability Recognition for Certain Employee Termination Benefits and Other
Costs to Exit an Activity (including Certain Costs Incurred in Restructuring)."
This statement requires recognition of a liability for a cost associated with an
exit or disposal activity when the liability is incurred, as opposed to when the
entity commits to an exit plan under EITF No. 94-3. SFAS No. 146 is to be
applied prospectively to exit or disposal activities initiated after December
31, 2002. The Company does not have any pending or planned exit or disposal
activities and does not expect a material effect on its financial position or
results of operations from the adoption of this statement.

         In April 2002 the FASB issued SFAS No. 145, "Rescission of FASB
Statements No. 4, 44, and 64, Amendment of FASB Statement No. 13, and Technical
Corrections." FASB No. 4 required all gains or losses from extinguishment of
debt to be classified as extraordinary items net of income taxes. SFAS No. 145
requires that gains and losses from extinguishment of debt be evaluated under
the provisions of Accounting Principles Board Opinion No. 30, and be classified
as ordinary items unless they are unusual or infrequent or meet the specific
criteria for treatment as an extraordinary item. This statement is effective
January 1, 2003. The Company does not anticipate that the adoption of this
statement will have a material effect on its financial position or results of
operations.

         On January 1, 2002 the Company adopted SFAS No. 144, "Accounting for
the Impairment or Disposal of Long-Lived Assets." There was no impact on the
Company's financial position or results of operations as a result of the
adoption of this statement.

         In June 2001 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 January 1, 2003. The Company has not yet
determined the impact of adoption of this statement.

                                       10

         On January 1, 2002 the Company adopted SFAS No. 142, "Goodwill and
Other Intangible Assets." There was no impact on the Company's financial
position or results of operations as a result of the adoption of this statement.

Overview

         When comparing the quarter ended June 30, 2002 to activity in 2001 the
focus will again be on oil and gas prices. Prices decreased compared to last
year but were higher this quarter than they were in the first quarter of 2002.
Our experience in the acquisition market during the quarter suggests to us that
this market may be moving toward our opinion of rationality. We remain hopeful
of meeting our acquisition budget this year. We continue to have a strong
balance sheet as a result of the $100.0 million senior convertible note private
placement we completed in the first quarter.

Three-Month Comparison

         Oil and Gas Production Revenues. Our quarterly oil and gas production
revenues decreased $9.2 million, or 17% to $46.2 million for the three months
ended June 30, 2002, compared with $55.4 million for the same period in 2001.

                                       12

The following table presents the components of increases or (decreases) between
2002 and 2001:

                                   Production      Price         Price
                                   % Change      $ Change      % Change
                                   ------------------------------------
    o    Natural Gas                   (4%)      ($1.05)/Mcf     (26%)
    o    Oil                           13%        $1.09/Bbl        4%

         Average net daily production increased to 150.1 MMCFE for 2002 compared
with 149.6 MMCFE in 2001. Our acquisition of properties from Choctaw in November
2001 added $3.4 million of revenue and average net daily production of 12.0
MMCFE to the second quarter of 2002. Other acquisitions and wells completed
during 2002 added average net daily production of 16.9 MMCFE. These increases in
average net daily production offset decreases from older properties.

         We hedged approximately 39% or 260 MBbls of our oil production for the
three months ended June 30, 2002, and realized a $1.2 million increase in oil
revenue attributable to hedging compared with a $775,000 decrease in 2001.
Without these contracts our average price would have been $23.64 per Bbl in the
second quarter of 2002 compared to $25.60 per Bbl in 2001. We also hedged 44% of
our 2002 second quarter gas production or 4.6 million MMBtu and realized a $1.5
million decrease in gas revenue compared with a $5.1 million decrease in gas
revenue in 2001. Without these contracts our average price would have been $3.18
per Mcf for the three months ended June 30, 2002, compared to $4.51 per Mcf for
the same period in 2001.

         Marketed Gas Revenue and Gas System Operating Expense. As a result of
our acquisition of gas gathering system lines in Cole County, Oklahoma in
February 2002 we started taking title to and marketing natural gas for third
parties. For the three months ended June 30, 2002 we received $2.9 million from
the sale of this natural gas. Operating costs associated with these revenues
totaled $2.7 million and resulted in gross margin to us of $277,000. Due to
fluctuations in natural gas prices, cost inflation and the variability of
production from oil and gas wells, we may not always have a positive gross
margin from marketing.

         Oil and Gas Production Costs. Oil and gas production costs consist of
lease operating expense, production taxes and transportation expenses. Total
production costs decreased $1.9 million or 14% to $11.5 million for the three
months ended June 30, 2002, from $13.4 million in 2001. In the second quarter of
2002 our Gulf Coast region experienced a $2.7 million decrease in LOE that was
comprised of a decrease in expense for non-recurring LOE and an adjustment due
to the issuance of a revised Authorization For Expenditure by the operator of
the Judge Digby field. This AFE indicated that non-recurring LOE we previously
expensed under the original AFE should be recorded as property, plant and
equipment. Our acquisition of properties from Choctaw in November 2001 added
$1.7 million of production costs in 2002 that were not reflected in 2001. Total
oil and gas production costs per MCFE decreased 15% to $0.84 for the three
months ended June 30, 2002 compared with $0.99 for 2001. A $0.07 per MCFE
decrease was due to the decrease in Gulf Coast non-recurring LOE. The Judge
Digby adjustment caused another $0.05 decrease. A $0.01 per MCFE increase was
due to the acquisitions previously discussed. A net $0.03 per MCFE decrease was
due to decreased production taxes partially offset by increased transportation
expenses.

         Depreciation, Depletion, Amortization and Impairment. Depreciation,
depletion and amortization expense ("DD&A") increased $395,000 or 3% to
$13.3 million for the three months ended June 30, 2002, from $12.9 million in
2001. DD&A per MCFE increased by 2% to $0.97 for the second quarter of 2002
compared with $0.95 in 2001. This increase reflects acquisitions and drilling
results in 2001 and 2002 that have added costs at a higher per-unit rate.

                                       13

         Exploration. Exploration expense increased $2.1 million or 100% to $4.3
million for the three months ended June 30, 2002, compared with $2.1 million in
2001. Percentages of total exploration expense are as follows:

                                                    2002       2001
                                                    ----       ----
     o   Geological and geophysical expenses         12%        26%
     o   Exploratory dry holes                       46%       -14%
     o   Overhead and other expenses                 42%        88%

         Oil and gas exploration is imprecise, and success can be affected by
numerous factors. Not every likely geological structure contains oil or natural
gas. Even when oil or natural gas is discovered there are no guarantees that
sufficient quantities can be produced to justify the completion of an
exploratory well. We have budgeted for additional geological and geophysical
expenses and expect to incur additional overhead and other expenses in the
pursuit of exploration, but we generally explore with an expectation of success.

         General and Administrative. General and administrative expenses
decreased $521,000 or 15% to $3.0 million for the three months ended June 30,
2002, compared with $3.5 million in 2001. We experienced a $491,000 increase in
COPAS overhead reimbursement from operations in this quarter.

         Interest Expense. Interest expense increased to $1.0 million for the
quarter ended June 30, 2002. This amount reflects accrued interest on our senior
convertible notes and will increase significantly on a comparative basis with
last year as we accrue and pay the interest due on the notes. The amount we
accrue and pay will be affected by the fixed-rate to floating-rate interest rate
swap we entered into in March 2002.

         Income Taxes. Income tax expense totaled $5.3 million for the three
months ended June 30, 2002, and $8.9 million in 2001, resulting in effective tax
rates of 33.2% and 38.4%, respectively. This decrease is a result of the tax
effect of interest expense on convertible debt with contingent interest
provisions combined with a lesser effect of state income taxes and an increase
in the effect on Section 29 credits on a lesser net income in 2002.

         Net Income. Net income for the three months ended June 30, 2002
decreased $3.6 million to $10.6 million compared with $14.2 million in 2001. A
26% decrease in gas prices and a 4% increase in oil prices combined with a 13%
increase in oil production and a 4% decrease in gas production resulted in a
$9.2 million decrease in oil and gas production revenue. This decrease was
offset by decreases of $1.9 million in oil and gas production costs and $3.6
million in income tax expense.

Six-Month Comparison

         Oil and Gas Production Revenues. We experienced a decrease in oil and
gas production revenues of $36.0 million, or 29% to $87.3 million for the six
months ended June 30, 2002, compared with $123.3 million for the same period in
2001. The following table presents the components of increases or (decreases)
between 2002 and 2001:

                                   Production      Price         Price
                                     %Change     $ Change      % Change
                                   ------------------------------------
     o   Natural Gas                   (2%)     ($1.95)/Mcf      (41%)
     o   Oil                           15%      ($0.57)/Bbl       (2%)

         Average net daily production increased to 151.6 MMCFE for the first six
months of 2002 compared with 148.4 MMCFE in 2001. Our acquisition of properties
from Choctaw in November 2001 added $6.7 million of revenue and average net
daily production of 12.1 MMCFE to the first six months of 2002. Other

                                       14

acquisitions and wells completed during 2002 added average net daily production
of 9.6 MMCFE. These increases offset declines in average net daily production
from older properties.

         We hedged approximately 39% or 542 MBbls of our oil production for the
six months ended June 30, 2002, and realized a $2.6 million increase in oil
revenue attributable to hedging compared with a $1.9 million decrease in 2001.
Without these contracts we would have received an average price of $22.46 per
Bbl for the six months ended June 30, 2002 compared to $26.48 per Bbl in 2001.
We also hedged 43% of our gas production or 9.0 million MMBtu and realized a
$904,000 increase in gas revenue for the six months ended June 30, 2002 compared
with a $20.4 million decrease in gas revenue in 2001. Without these contracts we
would have received an average price of $2.76 per Mcf for the six months ended
June 30, 2002, compared to $5.79 per Mcf for the same period in 2001.

         Marketed Gas Revenue and Gas System Operating Expense. As a result of
our acquisition of gas gathering system lines in Cole County, Oklahoma in
February 2002 we started taking title to and marketing natural gas for third
parties. For the six months ended June 30, 2002 we received $3.4 million from
the sale of this natural gas. Costs associated with these revenues totaled $3.1
million and resulted in gross margin to us of $358,000.

         Oil and Gas Production Costs. Total production costs increased slightly
to $25.6 million for the six months ended June 30, 2002, from $25.5 million in
2001. Our acquisition of properties from Choctaw added 2.6 million of LOE in
2002 that was not reflected in 2001. In the second quarter of 2002 our Gulf
Coast region experienced a $2.7 million decrease in LOE that was comprised of a
decrease in expense for non-recurring LOE and an adjustment due to the issuance
of a revised AFE by the Operator at Judge Digby. This AFE indicated that
non-recurring LOE we previously expensed under the original AFE should be
recorded as property, plant and equipment. This decrease offset $1.4 million of
increases we expected from general inflation. The decrease in oil and gas
production revenues caused a corresponding $1.6 million decrease in production
taxes. Total oil and gas production costs per MCFE decreased 2% to $0.93 for the
six months ended June 30, 2002 compared with $0.95 for 2001. A $0.07 per MCFE
decrease in production taxes offset a $0.05 per MCFE increase in LOE and
transportation costs. We continue to concentrate on these costs in an effort to
decrease the per MCFE amounts using a cost-benefit approach that will still
justify additional expenditures when appropriate.

         Depreciation, Depletion, Amortization and Impairment. DD&A
increased $2.2 million or 9% to $26.3 million for the six months ended June 30,
2002, from $24.2 million in 2001. DD&A per MCFE increased by 7% to $0.96 for
the six months ended June 30, 2002 compared with $.90 in 2001. This increase
reflects acquisitions and drilling results in 2001 and 2002 that added costs at
a higher per unit rate.

         Exploration. Exploration expense increased $701,000 or 7% to $11.2
million for the six months ended June 30, 2002, compared with $10.5 million in
2001. Percentages of total exploration expense are as follows:

                                                    2002       2001
                                                    ----       ----
     o   Geological and geophysical expenses         11%        22%
     o   Exploratory dry holes                       55%        42%
     o   Overhead and other expenses                 34%        36%


         General and Administrative. General and administrative expenses
decreased $1.4 million or 19% to $6.2 million for the six months ended June 30,
2002, compared with $7.6 million in 2001. We experienced a $955,000 increase in
COPAS overhead reimbursement from operations in this period and a $275,000
decrease in compensation expense caused primarily by decreased compensation
related to our incentive plans.

                                       15

         Interest Expense. Interest expense increased to $1.5 million for the
six months ended June 30, 2002. This amount reflects accrued interest on our
senior convertible notes and will increase significantly on a comparative basis
with last year as we accrue and pay the interest due on the notes in 2002. The
amount we accrue and pay will be affected by the fixed-rate to floating-rate
interest rate swap we entered into in March 2002.

         Income Taxes. Income tax expense totaled $6.4 million for the six
months ended June 30, 2002, and $20.4 million in 2001, resulting in effective
tax rates of 33.1% and 37.0%, respectively. This decrease is a result of the tax
effect of interest expense on convertible debt with contingent interest
provisions combined with a lesser effect of state income taxes and an increase
in the effect on Section 29 credits on a lesser net income in 2002.

         Net Income. Net income for the six months ended June 30, 2002 decreased
$21.7 million or 63% to $12.9 million compared with $34.6 million in 2001. A 41%
decrease in gas prices and a 2% decrease in oil prices combined with a 14%
increase in oil production and a 2% decrease in gas production resulted in a
$36.0 million decrease in oil and gas production revenue. This decrease was
offset by a corresponding $14.0 million decrease in income tax expense.

Liquidity and Capital Resources

         Our primary sources of liquidity are the cash provided by operating
activities, debt financing, sales of non-strategic properties and access to the
capital markets. All of these sources can be impacted by significant
fluctuations in oil and gas prices. An unexpected decrease in prices would
reduce expected cash flow from operating activities, might reduce the borrowing
base on our credit facility, could reduce the value of our non-strategic
properties and historically has limited our industry's access to the capital
markets.

         We use cash 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, debt financing and cash and cash
equivalents on hand. In the event of an unexpected decrease in oil and gas
prices, cash uses such as the acquisition of oil and gas properties and the
payment of stockholder dividends are discretionary and can be reduced or
eliminated. At any given point in time, we may be obligated to pay for
commitments to explore for or develop oil and gas properties or incur trade
payables. However, future obligations can be reduced or eliminated when
necessary. We are currently only required to make interest payments on our debt
obligations. An unexpected increase in oil and gas prices provides flexibility
to modify our uses of cash flow.

         We continually review our capital expenditure budget to reflect changes
in current and projected cash flow, acquisition opportunities, debt requirements
and other factors.

         Cash Flow. Net cash provided by operating activities increased $3.2
million or 4% to $76.1 million for the six months ended June 30, 2002 compared
with $72.9 million in 2001. The increase reflects the effect of a change between
years of $14.9 million from the collection of receivables and $15.1 million in
decreases of cash spent for other current assets and liabilities offset by the
effect of the decrease in oil and gas production revenues.

         Net cash used in investing activities increased $10.5 million or 19% to
$64.5 million for the six months ended June 30, 2002, compared with $54.0
million in 2001. This increase is due to a $9.4 million investment in short-term
securities in 2002 and a $3.9 million decrease in receipts from sales of KMOC
stock offset by decreased capital expenditures. Total capital expenditures,
including acquisitions of oil and gas properties, in the first six months of
2002 decreased $5.5 million or 9% to $56.2 million compared with $61.7 million
in the first half of 2001.

                                       16

         Net cash provided by financing activities increased $51.4 million to
$32.1 million for the six months ended June 30, 2002, compared with net cash
used in financing activities of $19.2 million in 2001. This increase reflects
our March 2002 private placement of $100.0 million of 5.75% senior convertible
notes due 2022. A portion of the net proceeds of $96.8 million was used to repay
the balance due on the credit facility. We have not repurchased any common stock
in the first six months of 2002.

         St. Mary had $47.9 million in cash and cash equivalents and had working
capital of $60.0 million as of June 30, 2002, compared with $4.1 million in cash
and cash equivalents and working capital of $34.0 million at December 31, 2001.
The increase in cash and cash equivalents reflects our issuance of $100.0
million of senior convertible notes during the first quarter of 2002.

         Senior Convertible Notes. In March 2002 we issued in a private
placement a total of $100.0 million of 5.75% senior convertible notes due 2022
with a 1/2% contingent interest provision. Interest payments will commence
September 15, 2002 and will be made on March 15 and September 15 of every year.
We received net proceeds of $96.8 million after deducting the initial
purchasers' discount and estimated offering expenses payable by us. The notes
are general unsecured obligations and rank on a parity in right of payment with
all our existing and future senior indebtedness and other general unsecured
obligations, and are senior in right of payment with all our future subordinated
indebtedness. The notes are convertible into our common stock at a conversion
price of $26.00 per share, subject to adjustment. We can redeem the notes with
cash in whole or in part at a repurchase price of 100% of the principal amount
plus accrued and unpaid interest including contingent interest beginning on
March 20, 2007. The note holders have the option of requiring us to repurchase
the notes for cash at 100% of the principal amount plus accrued and unpaid
interest including contingent interest upon (1) a change in control of St. Mary
or (2) on March 20, 2007, March 15, 2012 and March 15, 2017. If the note holders
request repurchase on March 20, 2007, we may pay the repurchase price with cash,
shares of our common stock valued at a discount to the market price at the time
of repurchase or any combination of cash and our discounted common stock. We are
not restricted from paying dividends, incurring debt, or issuing or repurchasing
our securities under the indenture for the notes. There are no financial
covenants in the indenture. We used a portion of the net proceeds from the notes
to repay our credit facility balance and will use the remaining net proceeds to
fund a portion of our 2002 capital budget. On March 25, 2002 we entered into a
five-year fixed-rate to floating-rate interest rate swap on $50.0 million of the
notes. The floating rate for each applicable six-month period will be determined
as LIBOR plus 0.36%. For the initial calculation period this rate was 2.69%.

         Credit Facility. The maximum loan amount under our long-term revolving
credit facility is $200.0 million. The amount actually available depends upon a
borrowing base that the lenders periodically redetermine based on the value of
our oil and gas properties and other assets. Since we pay commitment fees based
on the unused portion of the borrowing base, we have generally limited the
borrowing base which we have accepted to correspond to our actual funding
requirements. On April 10, 2002 the stated total possible borrowing base was
reduced by $10.0 million to $160.0 million and the accepted borrowing base was
reduced by $60.0 million to $40.0 million. The facility has a maturity date of
December 31, 2006, and includes a revolving period that matures on June 30, 2003
at which time all outstanding borrowings convert to a term loan payable in
quarterly installments through the facility maturity date. We must comply with
certain covenants including maintenance of stockholders' equity at a specified
level, restrictions on additional indebtedness, sales of oil and gas properties,
activities outside our ordinary course of business and certain merger
transactions. Borrowings under the facility are secured by a pledge of
collateral in favor of the banks and guarantees by subsidiaries. Such collateral
consists primarily of security interests in the oil and gas properties of St.
Mary and its subsidiaries.

         As of June 30, 2002 we had no balance outstanding under this credit
agreement, compared to $64 million at December 31, 2001. Pursuant to a March 4,
2002 amendment to the credit agreement, during the revolving period of the loan,
loan balances will accrue interest at our option of either (1) the higher of the
federal funds rate plus 1/2% or the prime rate, plus an additional 1/4% when our
debt to capitalization ratio is greater than 50%, or (2) the LIBOR rate plus (a)
1% when our debt to total capitalization ratio is less than 30%, (b) 1 1/4 %
when our debt to capitalization ratio is greater than or equal to 30% but less
than 40%, (c) 1 3/8% when our debt to capitalization ratio is greater than or

                                       17

equal to 40% but less than 50%, or (d) 1 5/8% when our debt to capitalization
ratio is greater than 50%. At June 30, 2002 our debt to capitalization ratio as
defined under the credit agreement was 25.2%.

     Schedule of Contractual Obligations.  The following table summarizes our
future estimated principal payments for the periods specified:

     Contractual                                                   Total Cash

     Total                 $100.0 million      $6.9 million      $106.9 million
                           ==============      ============      ==============

         In the period from 1-3 years, we have two leases of office space for
our regional offices that will expire. A third lease for office space will
expire in year 4. Estimated costs to replace these leases are not included in
the table above. For purposes of the table we assume that the holders of our
senior convertible notes will not exercise the conversion feature.

         Common Stock. 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 June 30, 2002 we have repurchased a cumulative total of 1,009,900 shares
of St. Mary's common stock under the program for $16.2 million at a weighted
average price of $15.86 per share, net of put option sale premiums received. We
anticipate that additional purchases of shares may occur as market conditions
warrant. Any future purchases will be funded with internal cash flow and
borrowings under our credit facility.

         Capital and Exploration Expenditures Incurred. Expenditures for
exploration and development of oil and gas properties and acquisitions are the
primary use of our capital resources. The following table sets forth certain
information regarding the costs incurred by us in our 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.

                                       18

         St. Mary's total costs incurred in the first six months of 2002
decreased $13.4 million or 20% compared to the first six months of 2001. We
spent $48.1 million in the first six months of 2002 for unproved property
acquisitions and domestic exploration and development compared to $68.2 million
for the comparable period in 2001. This decrease was a result of planned
decreases in drilling activity and a $1.5 million decrease in unproved leasehold
acquisition activity. We successfully obtained permits to begin producing our
two coalbed methane pilot programs located on fee acreage in the Hanging Woman
Basin. A total of 17 wells are being equipped for production and dewatering
began in May. In April we were successful in obtaining an additional 10,000
acres of leases bringing our total to 127,000 acres in the Hanging Woman Basin.
We are subject to an environmental public interest group lawsuit on 47,500 of
these acres. See "Legal Proceedings" for a discussion of this lawsuit.

         On April 26, 2002 the Interior Board of Land Appeals of the U.S.
Department of the Interior issued an order that reversed a decision by the U.S.
Bureau of Land Management dismissing a protest by the Wyoming Outdoor Council
and Powder River Basin Resource Council of the offer for sale in February 2000
of three oil and gas leases in the Powder River Basin in Wyoming. The Board held
that the BLM determination to allow the offer for sale of the three particular
leases did not comply with environmental laws since the environmental analysis
used by the BLM in making that determination did not contain a discussion of the
unique potential impacts associated with coalbed methane extraction and
development or consider reasonable alternatives relevant to a pre-leasing
environmental analysis. The order addressed only three particular leases
covering approximately 2,600 acres that are not included in our Hanging Woman
Basin project. However, we cannot assure you that other leases, including issued
leases that we hold in the Hanging Woman Basin, will not be challenged on a
similar basis.

         In November 2001 we purchased oil and gas properties from Choctaw II
Oil & Gas, Ltd. for $40.5 million in cash. We used a portion of our credit
facility for this acquisition. The properties are primarily located in the
Williston Basin of Montana and North Dakota and in the Green River Basin of
Wyoming.

         Capital Expenditure Budget. We anticipate spending approximately $164.0
million for capital and exploration expenditures in 2002 with $60.0 million for
acquisitions. Budgeted ongoing exploration and development expenditures in 2002
for each of our core areas is as follows (in millions):

     o   Mid-Continent region                                  $  40.0
     o   Gulf Coast and Gulf of Mexico region                     15.0
     o   ArkLaTex region                                          14.0
     o   Williston Basin                                          20.0
     o   Permian Basin                                             8.0
     o   Other                                                     7.0
                                                               -------
         Total                                                 $ 104.0
                                                               =======

         We believe the amount not funded from our internally generated cash
flow in 2002 can be funded from our existing cash and 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. If
additional development or attractive acquisition opportunities arise, we may
consider other forms of financing, including the public offering or private
placement of equity or debt securities.

         Derivatives. We seek to protect our rate of return on acquisitions of
producing properties by hedging cash flow when the economic criteria from our
evaluation and pricing model indicate it would be appropriate. Management's

                                       19

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. Management reviews these hedging parameters on
a quarterly basis. We anticipate this strategy will result in the hedging of
future cash flow from acquisitions. We generally limit our 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 our
areas of gas production. Including hedges entered into since June 30, 2002 we
have the following swaps in place:

Swaps:
                        Average       Quantity      Average
        Product      Volumes/month      Type      Fixed price      Duration
        -------      -------------    --------    -----------      --------

      Natural Gas      1,058,000       MMBtu         $2.85       07/02 - 12/02
      Natural Gas        468,000       MMBtu         $3.34       01/03 - 12/03
      Natural Gas        229,000       MMBtu         $3.81       01/04 - 12/04

         Oil              57,700        Bbls        $24.77       07/02 - 12/02
         Oil              49,800        Bbls        $22.68       01/03 - 12/03

         On February 4, 2002 we entered into an agreement to monetize our
unrealized hedge gain receivable due from Enron for $1.1 million. This amount
was included in other comprehensive income at December 31, 2001, is recorded in
oil hedge gain and is reported in oil and gas production revenues on our
consolidated statements of operations. Amortization of $609,000 of other
comprehensive income related to our commodity positions with Enron is also
recorded in oil hedge gain. Additional amortization will be recorded in oil
hedge gain in future months. Unrealized derivative gain on the consolidated
statements of operations includes $54,000 of net gain from oil and gas hedge
ineffectiveness.

         Our senior convertible notes contain a provision for payment of
contingent interest if certain conditions are met. Under Statement of Financial
Accounting Standards No. 133 this provision is considered an embedded
equity-related derivative that is not clearly and closely related to the fair
value of an equity interest and therefore must be separated and accounted for as
a derivative instrument. The value of the derivative at issuance was $474,000.
This amount was recorded as a decrease to the convertible notes payable on the
consolidated balance sheets. Of this amount, $28,000 has been amortized through
interest expense. Unrealized derivative gain on the consolidated statements of
operations includes $245,000 of net loss from mark-to-market adjustments for
this derivative.

         Our fixed-rate to floating-rate interest rate swap on $50.0 million of
senior convertible notes did not qualify for fair value hedge treatment under
SFAS No. 133. Unrealized derivative gain on the consolidated statements of
operations includes $2.2 million of net gain from mark-to-market adjustments for
this derivative.

         We anticipate that all hedge transactions will occur as expected.

Accounting Matters

New Accounting Standards

         In June 2002 the FASB issued SFAS No. 146, "Accounting for Costs
Associated with Exit or Disposal Activities." FASB No. 146 requires recognition
of a liability for a cost associated with an exit or disposal activity when the
liability is incurred, as opposed to when the entity commits to an exit plan
under EITF No. 94-3. This statement is to be applied prospectively to exit or
disposal activities initiated after December 31, 2002. We have not determined
the impact of adoption of this statement.

                                       20

         In April 2002 the FASB issued SFAS No. 145, "Rescission of FASB
Statements No. 4, 44, and 64, Amendment of FASB Statement No. 13, and Technical
Corrections." FASB No. 4 required all gains or losses from extinguishment of
debt to be classified as extraordinary items net of income taxes. SFAS No. 145
requires that gains and losses from extinguishment of debt be evaluated under
the provisions of Accounting Principles Board Opinion No. 30, and be classified
as ordinary items unless they are unusual or infrequent or meet the specific
criteria for treatment as an extraordinary item. This statement is effective for
fiscal years beginning after May 15, 2002. We do not anticipate that the
adoption of this statement will have a material effect on our financial position
or results of operations.

         In June 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 January 1, 2003. We
have not determined the impact of adoption of this statement.

Compensation Expense

         We have a net profits interest incentive bonus plan for key employees
designated as participants by our board of directors. Under the plan oil and gas
wells that are completed or acquired during a year are designated as a pool.
Participants employed by us on the last day of that year vest and become
entitled to bonus payments after we recover net revenues generated by the pool
equal to 100% of our investment in that pool. Thereafter an amount equal to10%
of net revenues generated by the pool will be split among the participants and
paid on a quarterly basis. The percentage of net revenues from the pool to be
split among the participants increases to 20% after we recover net revenues
equal to 200% of our investment.

         Beginning in 2002 we changed our method of accounting to record
estimated compensation expense related to future amounts payable to participants
under the plan on a quarterly basis in the plan year that the participants vest.
The estimated compensation expense will be based on a number of assumptions
including estimates of oil and gas production, oil and gas prices, recurring and
non-recurring lease operating expense and a present value discount factor. We
use a discount factor to calculate present value that reflects recovery of our
investment, the timing of payments to participants and uncertainties associated
with our estimates. The estimates we use will change from year-to-year based on
new information and any change in estimated compensation will be recorded in the
period that information becomes available.

ITEM 3.  QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

         We hold 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.

         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 -
Finance must review and approve all risk management programs that use
derivatives. The board of directors periodically reviews these programs.

         Commodity Price Risk. We use various hedging arrangements to manage our
exposure to price risk from 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

                                       21

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 value 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 value of the futures are
based on quoted market prices obtained from the New York Mercantile Exchange and
have been adjusted for our hedging of the basis differential accorded to the
pipelines relative to our areas at production.

         A hypothetical $0.10 per MMBtu change in our quarter-end market prices
for natural gas swaps and futures contracts on a notional amount of 18.1 million
MMBtu would cause a potential $1.6 million change in net income before income
taxes for contracts in place on June 30, 2002. 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 1.4 million Bbls would cause a potential $1.3 million
change in net income before income taxes for oil contracts in place on June 30,
2002. 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.

         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, 2002, 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, 2002, we had floating rate debt of $50.0 million and
$50.0 million of 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
$250,000 before taxes.

PART II.  OTHER INFORMATION

ITEM 1.  Legal Proceedings
         -----------------

                  On March 27, 2002 Nance Petroleum Corporation, a wholly owned
         subsidiary, was named along with several other leaseholders and
         interested parties as an additional co-defendant in a lawsuit that was
         originally filed on June 12, 2001 in the U.S. District Court for the
         District of Montana by the Northern Plains Resource Council, Inc., an
         environmental public interest group, against the U.S. Bureau of Land
         Management, the U.S. Secretary of the Interior, the Montana BLM State
         Director and Fidelity Exploration & Production Company. The
         lawsuit, which was reported in our 2001 Form 10-K and our first quarter
         2002 Form 10-Q, seeks the cancellation of all federal leases related to
         coalbed methane development issued by the BLM in Montana since January
         1, 1997, primarily on the grounds of an alleged failure of the BLM to
         comply with federal environmental laws by analyzing the environmental
         impacts of coalbed methane development before issuing the challenged
         leases. The lawsuit potentially affects 47,500 acres subject to federal
         leases of the 127,000 total acres in our Hanging Woman Basin coalbed
         methane project. While we believe, based on information presently
         available to us that the applicable environmental laws have been
         complied with, there is no assurance of the outcome of the lawsuit and
         therefore there is no assurance that it will not adversely affect our
         coalbed methane project. However, even if the federal leases in Montana
         become unavailable, we anticipate continuing with the Hanging Woman
         Basin project in Wyoming and obtaining additional non-federal leases in
         Montana. See "Management's Discussion and Analysis of Financial
         Condition and Results of Operations" for a discussion of other recent
         coalbed methane legal developments.

                                       22

                  As previously reported in our first quarter 2002 Form 10-Q, on
         May 1, 2002 GNK Acquisition Corp., a recently acquired wholly owned
         subsidiary, was served in a lawsuit that was filed earlier in 2002 in
         the District Court in Shelby County, Texas, by Samson Lone Star Limited
         Partnership against GNK Acquisition Corp. and GNK, Inc., the previous
         owner of GNK Acquisition Corp. The lawsuit primarily involves a claim
         related to certain oil and gas leasehold positions acquired by GNK
         Acquisition Corp. under a contractual preferential right to purchase
         that was triggered by an attempt by Samson to acquire such leasehold
         positions from the party that sold the positions to GNK Acquisition
         Corp. Samson alleges that it should be entitled to acquire a portion of
         such positions as a result of an agreement it had with GNK, Inc. An
         answer by GNK Acquisition Corp. to the underlying petition by Samson
         has been filed, and discovery has begun. Although the lawsuit is in a
         very preliminary stage and there can be no assurance of the ultimate
         outcome, we do not believe based on the information presently available
         that the lawsuit will have a material adverse effect on our financial
         condition or results of operations.

ITEM 2.  Changes in Securities and Use of Proceeds
         -----------------------------------------

(c)      On June 4, 2002 St. Mary issued 800 restricted shares of common stock
         to a newly elected director as compensation recorded in the amount of
         $14,763 for services as a member of the board of directors. These
         shares were not registered under the Securities Act of 1933 in reliance
         on Rule 506 of Regulation D promulgated under the Securities Act since
         the director is an accredited investor and certificates representing
         the shares bear a legend restricting the transfer of those shares.

ITEM 4.  Submission of Matters to a Vote of Security Holders
         ----------------------------------------------------

         At the Company's annual stockholders' meeting on May 20, 2002, the
         stockholders approved management's current slate of directors. The
         directors elected and the vote tabulation for each director are as
         follows:

                  Mark A. Hellerstein         19,273,374           558,030
                  Robert L. Nance             19,273,354           558,050
                  Arend J. Sandbulte          19,273,354           558,050
                  John M. Seidl               19,273,354           558,050

         Also at the Company's annual stockholders' meeting on May 20, 2002, the
         stockholders did not approve a proposed amendment to the Company's
         certificate of incorporation to authorize the issuance of up to a total
         of 5,000,000 shares of preferred stock with such powers, preferences,
         rights and limitations as the board of directors may designate from
         time to time. The tabulation of votes for that proposal is as follows:

                  For:               7,822,200
                  Against:           8,963,607
                  Abstain:             377,120
                  Not Voted:         2,668,477
