ITEM 5.           OTHER EVENTS.

On July 27, 1999, St. Mary Land & Exploration Company (the "Registrant") entered
into an agreement to acquire King Ranch Energy,  Inc.  ("KRE"),  a subsidiary of
King  Ranch,  Inc.,  in a merger in which the  Registrant  will issue  2,666,252
shares of its common stock to  shareholders  of King Ranch and KRE will become a
wholly  owned  subsidiary  of  the  Registrant.  KRE's  properties  are  located
primarily  in the  Gulf of  Mexico  and  the  onshore  Gulf  Coast.  KRE's  1998
production was 48.8 MMCF equivalent per day. KRE's reported reserves at December
31, 1998,  plus an acquisition  made early in 1999, were 64.7 BCF equivalent and
82% natural gas. The merger  agreement,  which has been unanimously  approved by
the Boards of Directors of both  companies,  is subject to obtaining a favorable
vote of the shareholders of the Registrant and King Ranch.

The press release of the Registrant  announcing the merger agreement is filed as
Exhibit 99.1 to this report.
