         $7.32 per share tender offer price, (ii) an estimated 522,500 shares of
         common stock subject to options with an exercise price of less than
         $7.32 per share, multiplied by $7.32 less $6.89, the average exercise
         price of such options, and (iii) 265,000 shares of common stock subject
         to warrants multiplied by $7.32 less $7.00, the exercise price of such
         warrants.

**       Calculated as 1/50 of 1% of the transaction value.

         This Amendment No. 2 is the final amendment to, and amends and
supplements, the Tender Offer Statement on Schedule TO (the "Schedule TO"), as
amended through the date hereof, filed initially with the Securities and
Exchange Commission on November 15, 2001 by Comstock Acquisition Inc., a
Delaware corporation ("Purchaser") and a wholly owned subsidiary of Comstock
Holdings, Inc., a Delaware corporation ("Holdings"), which, in turn, is a wholly
owned subsidiary of Comstock Resources, Inc., a Nevada corporation ("Comstock").
The Schedule TO relates to the offer by Purchaser to purchase all outstanding
shares of common stock, par value $0.234 per share (the "Shares"), of DevX
Energy, Inc., a Delaware corporation ("DevX"), at a purchase price of $7.32 per
Share, net to the seller in cash, upon the terms and subject to the conditions
set forth in the Offer to Purchase dated November 15, 2001 (the "Offer to
Purchase") and in the related Letter of Transmittal, copies of which were filed
as Exhibits (a)(1) and (a)(2) to the Schedule TO (which, together with any
amendments or supplements thereto, collectively constitute the "Offer").
Capitalized terms used and not otherwise defined herein shall have the meanings
assigned to them in the Offer to Purchase or the Schedule TO.

ITEM 8. (INTEREST IN SECURITIES OF THE SUBJECT COMPANY) AND ITEM 11.
(ADDITIONAL INFORMATION).

           Items 8 and 11 of the Schedule TO are hereby amended and supplemented
to adding to the end thereof the following:

           "The Offer expired at 12:00 midnight, New York City time, on
Thursday, December 13, 2001. Based on information provided by the Depositary to
Purchaser, as of the expiration of the Offer, 12,283,728 Shares had been
tendered and not withdrawn (including guaranteed deliveries), representing
approximately 97% of the issued and outstanding Shares. Purchaser has accepted
for purchase and payment all shares validly tendered and not withdrawn pursuant
to the Offer. Comstock issued a press release, a copy of which is attached
hereto as Exhibit (a)(10) and is incorporated herein by reference.

           Comstock intends to complete the acquisition of DevX as soon as
practicable through the Merger in which each Share of DevX common stock not
previously purchased in the Offer will be converted into the right to receive
$7.32 per Share in cash, without interest (subject to applicable dissenter's
rights). The Merger may be consummated without a vote of DevX's stockholders.
Once the Merger becomes effective, DevX will become an indirect wholly owned
subsidiary of Comstock."
