Suite 500
Frisco, Texas 75034

Dear Roland:

         Friedman, Billings, Ramsey & Co., Inc. ("FBR"), as arranger for Toronto
Dominion (Texas), Inc. ("TDTX") and HPC Holding Company ("HPC") is pleased to
advise you that, subject to the terms and conditions herein, TDTX and HPC are
each willing to provide Comstock Holdings, Inc. (the "Borrower") with 50% of a
$57,000,000 Senior Secured Acquisition Loan (the "Credit Facility"), as outlined
in Exhibit A described below.

         The Credit Facility will be used to fund the acquisition of shares of
DevX Energy, Inc. ("DevX") by Comstock Acquisition, Inc. ("Acquisition"), a
wholly-owned subsidiary of the Borrower, all as more fully described in the
Proposed Summary of Terms and Conditions attached hereto as Exhibit A (the "Term
Sheet").

         FBR will act as an advisor and arranger for the Credit Facility and
TDTX will act as the sole and exclusive administrative agent. As we have
discussed, FBR has solicited commitments from TDTX and HPC (together, the
"Lenders") prior to the execution of this commitment letter in an amount
sufficient to provide the Credit Facility.

         The Credit Facility will be provided pursuant to the terms and
conditions of, and shall become effective only upon the execution and delivery
of, a mutually satisfactory credit agreement and other definitive loan
documentation incorporating the terms and conditions set forth in the Term
Sheet, your payment of certain fees set forth in the Term Sheet and other terms
and conditions customarily included in credit facilities of this type, amount
and purpose. These terms and conditions will necessarily be further developed
during the course of preparing and negotiating the loan documentation.








         The Borrower agrees to indemnify and hold harmless FBR, the Lenders,
their affiliates and their respective officers, directors, employees, advisors
and agents (each, an "Indemnified Person") from and against any and all losses,
claims, damages and liabilities to which any such Indemnified Person may become
subject arising out of or in connection with this letter, the Credit Facility,
the use of proceeds thereof, the other transactions contemplated hereby, any
related transaction or any claim, investigation or proceeding relating to any of
the foregoing, regardless of whether any Indemnified Person is a party thereto,
and to reimburse each Indemnified Person upon demand for any costs or expenses
(including legal fees) incurred in connection with investigating or defending
any of the foregoing, provided that the foregoing indemnity will not, as to any
Indemnified Person, apply to losses, claims, damages or liabilities to the
extent they arise from the willful misconduct or gross negligence of such
Indemnified Person. No Indemnified Person shall be liable for any indirect or
consequential damages in connection with its activities related to this letter
or the Credit Facility.

         In addition, whether or not any loans are made, the Borrower agrees to
reimburse FBR, TDTX and their affiliates on demand for all out-of-pocket
expenses (including, without limitation, travel expenses and reasonable fees,
charges and disbursements of counsel) incurred in connection with the Credit
Facility and the preparation, review, negotiation, execution and delivery of any
related documentation, whether or not executed (including this letter, the Term
Sheet and definitive financing documentation) and the administration, amendment,
modification or waiver thereof.

         The terms of this letter may be accepted by Comstock prior to 10:00
p.m. (New York time) on November 14, 2001 in the manner indicated in the final
paragraph of this letter. If this letter is not so accepted by such time on that
date, this commitment shall automatically expire unless extended in writing by
FBR.

         In addition, unless extended in writing at the sole discretion of FBR,
all obligations of FBR, TDTX and HPC under this letter or the Term Sheet shall
expire automatically, without further act and regardless of cause or
circumstances on January 11, 2002 if definitive loan documentation is not
executed and delivered by all the parties thereto and initial loans disbursed on
or prior to such date. Notwithstanding anything stated herein to the contrary,
the compensation, reimbursement and indemnification provisions hereof shall
survive any termination or expiration hereof, regardless of whether definitive
financing agreements are executed.

         This letter is delivered to you on the condition that neither its
existence nor any of its contents shall be disclosed by you to any person or
entity without FBR's prior written approval, except (i) as may be compelled to
be disclosed in a judicial or administrative proceeding or as otherwise required
by law, (ii) as may be disclosed on a confidential and "need to know" basis to
your directors, officers, employees, advisers, and agents, and (iii) after your
acceptance of the terms hereof, the existence of this letter and a summary of
the principal terms and conditions of the commitments hereunder may be disclosed
in any public filings to be made in connection with the tender offer for DevX
(as defined in the Term Sheet), provided that any such disclosure that



                                        2



is in the writing shall be subject to FBR's prior review and approval, such
approval not to be unreasonably withheld.

         If the foregoing is satisfactory to you, please have the enclosed copy
of this letter duly executed by an authorized officer and return copies to us.
This letter may be executed in any number of counterparts, each of which shall
be an original and all of which, when taken together, shall constitute one
agreement. This letter and the Term Sheet may not be assigned by you without the
prior written consent of FBR and may not be amended or any provision hereof or
thereof waived or modified except by an instrument in writing signed by each of
the parties hereto. No person or entity other that the parties hereto TDTX and
HPC shall have any rights under or be entitled to rely upon this letter or the
Term Sheet. This letter and the Term Sheet shall be governed by and construed in
accordance with the law of the State of New York. Delivery of an executed
signature page by facsimile shall be effective execution and delivery.

         Please indicate your consent and agreement by your signature below.

                                          Very truly yours,
