ITEM 5.   OTHER EVENTS

     On February 11, 2000, Costilla Energy, Inc. (the "Company") filed a
proposed Plan of Reorganization (the "Plan") in its bankruptcy proceeding styled
In re:  Costilla Energy, Inc., Case No. 99-70653 in the United States Bankruptcy
Court for the Western District of Texas, Midland Division.  The Plan, which is
subject to the approval of the Bankruptcy Court, sets forth the means for
addressing claims against and interest in the Company. The following is a brief
summary of the treatment of certain types of claims under the Plan.

     Under the proposed Plan, the Company's existing common and preferred stock
will be canceled and the holders thereof will not receive any distributions.
Holders of the Company's 10 1/4% Senior Notes due 2006, together with the other
unsecured creditors, will receive New Common Stock representing 100% ownership
of the reorganized company.  The Company's bank credit facility will be treated
as a secured claim which may be satisfied by either refinancing provided by
other parties or restructuring with the existing bank group.  Any allowed claim
related to the Company's commodity hedging contracts will be treated as a
secured claim that may also be satisfied either by refinancing or a
restructuring.

     Consummation of the Plan will require approval of the U.S. Bankruptcy
Court.  There are no assurances that the Plan will be approved or when the
effective date of a plan will be set.  The Company intends to file a disclosure
statement relating to the Plan on or before February 29, 2000.

     The Company issued a press release regarding the foregoing on February 11,
2000, a copy of which is attached hereto as Exhibit 99.1.
