ITEM 5. OTHER EVENTS

         On November 12, 2001, DevX Energy, Inc. (the "Company") entered into an
Agreement and Plan of Merger (the "Merger Agreement") with Comstock Resources,
Inc., a Nevada corporation ("Comstock"), Comstock Holdings, Inc., a Delaware
corporation and wholly owned subsidiary of Comstock ("Holdings"), and Comstock
Acquisition Inc, a Delaware corporation and a wholly owned subsidiary of
Holdings (the "Purchaser"), pursuant to which Purchaser agreed to acquire all of
the issued and outstanding shares of common stock of the Company for $7.32 per
share cash. The acquisition will be effected by a first step cash tender offer
(the "Offer") for all of the Company's issued and outstanding common stock. The
tender offer is expected to commence on November 15, 2001, or as soon thereafter
as practicable, and to remain open for at least 20 business days. The Offer will
be followed by a merger in which shareholders whose shares are not acquired in
the tender offer will receive $7.32 per share in cash (the "Merger"). In the
Merger, the Purchaser will be merged with and into the Company and the Company
will become a wholly owned subsidiary of Holdings. The Offer is conditioned
upon, among other things, there having been validly tendered and not withdrawn
prior to the expiration date greater than 50% of the number of then outstanding
shares (including all shares issuable upon the exercise of then-outstanding
option or warrants to purchase shares).

statements within the meaning of Section 27A of the Securities Act of 1933 and
Section 21E of the Securities Exchange Act of 1934. Such forward-looking
statements involve known and unknown risks, uncertainties and other factors that
may result in either the Offer or the Merger not being consummated. These risks

Merger. In addition, either party may terminate the Merger Agreement upon
