Item 1.01   Entry into a Material Definitive Agreement.

         On April 7, 2005, St. Mary Land & Exploration Company (the
"Company") entered into a new $500 million senior secured five-year revolving
credit facility (the "Facility"). The Facility replaces the Company's prior $300
million revolving credit facility, and was entered into as an Amended and
Restated Credit Agreement among the Company, Wachovia Bank, National
Association, as administrative agent, Wells Fargo Bank, N.A., as syndication
agent, BNP Paribas, Comerica Bank - Texas and JPMorgan Chase Bank, N.A., as
co-documentation agents, and the following other participating commercial
lending institutions: U.S. Bank National Association, Royal Bank of Canada, Bank
of Scotland, Hibernia National Bank and Key Bank. The maturity date of the
Facility is April 7, 2010.

         The Facility is available for general corporate borrowing purposes of
the Company. The maximum loan amount of $500 million is subject to a borrowing
base which is determined based on the value of the Company's oil and gas
properties. The initial borrowing base for the Facility has been set at $400
million and the Company has elected an initial commitment of $200 million. Upon
entering into the Facility on April 7, 2005, the Company had $32 million of bank
debt outstanding. Borrowings under the Facility are secured by the majority of
the Company's oil and gas properties and a pledge of the common stock of
material subsidiary companies. Interest and commitment fees are based on the
following borrowing base utilization table:

Borrowing Base
Utilization Percentage          <50%       >50% <75%     >75% <90%       >90%
- --------------------------- ------------ ------------- ------------ -------------
Eurodollar Loans                1.000%       1.250%        1.500%       1.750%
- --------------------------- ------------ ------------- ------------ -------------
ABR Loans                       0.000%       0.000%        0.250%       0.500%
- --------------------------- ------------ ------------- ------------ -------------
Commitment Fee                  0.250%       0.300%        0.375%       0.375%
- --------------------------- ------------ ------------- ------------ -------------

         The Facility contains customary representations and warranties and
affirmative and negative covenants, including, but not limited to, the following
financial covenants: (a) the Company's ratio of Total Debt to EBITDA (as defined
in the Facility) for the four fiscal quarters ending on the last day of a fiscal
quarter may not be greater than 3.5 to 1.0 and (b) the Company's current ratio
(as defined in the Facility) as of the last day of a fiscal quarter may not be
less than 1.0 to 1.0. In addition, the Facility has covenants restricting the
incurrence of Debt outside of the Facility and limiting the Company's annual
cash dividend rate to no more than $0.25 per common share. Any violation of
these covenants could result in a default under the Facility which would permit
the participating banks to restrict the Company's ability to access the Facility
and require the immediate repayment of any outstanding borrowings under the
Facility.

         Certain lenders that are a party to the Facility have in the past
performed, and may in the future from time to time perform, investment banking,
financial advisory, lending or commercial banking or trustee services for the
Company and its subsidiaries, for which they have received, and may in the
future receive, customary compensation and reimbursement of expenses.
