                       COMSTOCK RESOURCES, INC. COMPLETES
                       TENDER OFFER FOR DEVX ENERGY, INC.

FRISCO, TEXAS, DECEMBER 17, 2001 - Comstock Resources, Inc. ("Comstock" or the
"Company")(NYSE:CRK) announced today and DevX Energy, Inc. ("DevX")(Nasdaq:DVXE)
announced today the completion of the cash tender offer by Comstock Acquisition
Inc., an indirect wholly owned subsidiary of Comstock, for all of the issued and
outstanding shares of common stock of DevX. The tender offer, priced at $7.32 in
cash per share, expired on Thursday, December 13, 2001. The Depository for the
tender offer has advised Comstock that as of the expiration of the tender offer,
12,283,728 shares had been validly tendered and not withdrawn, representing
approximately 97% of DevX's issued and outstanding common shares.

Comstock intends to complete the acquisition of DevX later today through a
merger in which each share of DevX common stock not previously purchased in the
tender offer will be converted into the right to receive $7.32 per share in
cash, without interest (subject to applicable dissenter's rights). This merger
may be consummated without a vote of DevX's stockholders. Once this merger
becomes effective, DevX will become an indirect wholly owned subsidiary of
Comstock.

DevX is an independent energy company based in Dallas, Texas engaged in the
exploration, development and acquisition of oil and gas properties. DevX owns
interest in 636 producing oil and gas wells located onshore primarily in East
and South Texas, Kentucky, Oklahoma and Kansas. Comstock estimates that the
acquisition of DevX will add approximately 155 billion cubic feet equivalent of
natural gas reserves to Comstock's proved oil and gas reserve base. DevX's oil
and gas reserves are 96% natural gas and are 69% proved developed.

Comstock also announced that it has entered into agreements to acquire
approximately $45 million of the outstanding $50 million of DevX's 12.5% Senior
Notes due in 2008 for 110% of the principal amount plus accrued interest.

The acquisition is being financed with borrowing under a new $350 million Senior
Secured Revolving Facility being provided by TD Securities (USA) Inc. The three
year revolving credit facility will have an initial borrowing base of $270
million and will also be used to refinance Comstock's existing bank debt.
