2001 EXPLORATION AGREEMENT


     This 2001 Exploration  Agreement (the "Agreement") is effective as of April
1, 2001 (the "Effective Date") by and among Comstock  Resources,  Inc., a Nevada
corporation ("CRI"),  Comstock Offshore, LLC, a Nevada limited liability company
("Comstock"),  Bois d'Arc  Offshore,  Ltd., a Texas limited  partnership  ("Bois
d'Arc  Ltd."),  Bois d'Arc Oil & Gas  Company,  LLC, a Texas  limited  liability
company ("Bois d'Arc LLC") (Bois d'Arc Ltd. and Bois d'Arc LLC are  collectively
referred to herein as ("Bois  d'Arc")),  Wayne L. Laufer  ("Laufer") and Gary W.
Blackie ("Blackie").

     WHEREAS,  Comstock and Bois d'Arc desire to enter into a joint  exploration
program with respect to certain oil and gas properties  within the state coastal
waters of Louisiana and Texas and  corresponding  federal  offshore  waters (the
"Region"), as identified by Bois d'Arc;

     WHEREAS, Laufer and Blackie are the principals of Bois d'Arc; and

     WHEREAS,  certain of the parties  hereto  previously  entered  into a Joint
Exploration  Agreement dated December 8, 1997 (the "1997 Agreement") pursuant to
which Bois d'Arc (and its predecessors)  identified prospects,  acquired seismic
data and performed other work; the parties desire that such prospects be further
developed  and  completed  pursuant to the terms of this  Agreement and that the
1997 Agreement be terminated.

     NOW, THEREFORE,  in consideration of the mutual agreements herein contained
and other good and valuable consideration,  the receipt and sufficiency of which
are hereby acknowledged, the parties hereby agree as follows:

1.   Bois d'Arc's responsibilities shall be as follows:

(a)  Bois d'Arc shall identify oil and natural gas prospects  within the Region.
     A prospect  shall be  considered to be the entire  lease(s)  which is (are)
     expected  to be  underlain  by  any  portion  of a  potentially  productive
     reservoir(s) expected to be encountered by the initial test well.

(b)  Bois d'Arc shall develop a budget for  exploration  activities with respect
     to  prospects  within  the  Region,   including  the  prospects   initially
     identified  pursuant  to the 1997  Agreement  (as  listed  on the  Schedule
     hereto) (the  "existing  prospects"),  which budget shall be subject to the
     approval of Comstock (the "Budget").  If Comstock elects not to participate
     in a particular prospect within thirty (30) days following submittal of the
     prospect by Bois d'Arc to Comstock (by rejecting inclusion of such prospect
     in the Budget),  Bois d'Arc shall have the right to pursue such prospect on
     its own and  shall  have no  further  obligation  to  Comstock  under  this
     Agreement with respect to such prospect.

(c)  With respect to potential  prospects that the parties have  approved,  Bois
     d'Arc shall acquire the seismic  data,  and if  appropriate,  the leasehold
     interests.  All costs for seismic data,  leasehold  acquisitions  and other
     exploration activities shall be in accordance with the Budget.



(d)  Bois  d'Arc  shall  be  responsible  for  fully   developing  the  acquired
     prospects.  Upon  completion  of  the  initial  test  well  for a  prospect
     (resulting in a Successful  Prospect (as defined below)),  Bois d'Arc shall
     assign the entire  working  interest  40% to Comstock and 60% to Bois d'Arc
     (or  their  respective  designees),  except  that (i) with  respect  to the
     existing  prospects,  the interest to be assigned to each party shall be as
     set forth on the  attached  Schedule and (ii)  Comstock  will receive a 50%
     working interest in any potential  prospect at Ship Shoal 67 or South Pelto
     1 on future  acquisitions of State leases,  and all assignments will in all
     events be subject to (x) a 2% of 8/8ths  overriding  royalty interest to be
     reserved for Bois d'Arc (or its  designees),  (y) the  operating  agreement
     naming Bois d'Arc Ltd. as operator  with respect to the  prospects  and (z)
     the terms of this Agreement.  Notwithstanding  the foregoing,  in the event
     that all warrants available for issuance hereunder as provided in Section 3
     below are earned and issued prior to the Expiration Date (as defined below)
     and CRI does not make additional warrants available for issuance hereunder,
     Bois d'Arc  shall have the option to allocate  the  working  interest to be
     assigned for such future  prospects  (for which no warrants are issued) 20%
     to  Comstock  and 80% to  Bois  d' Arc  (and  subject  to the 2% of  8/8ths
     override and other exceptions noted in the preceding sentence).

(e)  Laufer and Blackie  shall devote such amount of their time and energy as is
     necessary for Bois d'Arc to identify, pursue and develop the prospects.

2.   (a) Comstock's  responsibilities  shall be as follows:  Comstock shall make
     advances  to  Bois  d'Arc  to fund  100% of the  costs  for  seismic  data,
     leasehold  acquisitions  and other  exploration  activities.  Such advances
     shall be made in  accordance  with the Budget.  Bois d'Arc shall  reimburse
     Comstock for these  advances  when a prospect is developed  and assigned to
     the parties.  Lease acquisition costs,  including any related delay rentals
     and legal costs,  will be reimbursed to Comstock when the working  interest
     is assigned,  as provided in Section 1(d).  Bois d' Arc shall determine and
     charge a seismic fee for each developed prospect. The amount of the seismic
     fee  charged is to be based on past  practices  followed by Bois d'Arc with
     the objective of recovering  the amounts  advanced by Comstock  pursuant to
     this Agreement. Comstock will be paid 100% of such seismic fees received by
     Bois  d'Arc  until  Comstock  has  recovered  100%  of  any  advances  made
     hereunder.  After such time,  Bois d'Arc and Comstock will each receive 50%
     of any excess fee income.

(b)  The  parties  acknowledge  and agree  that  Comstock  and Bois  d'Arc  have
     previously  funded  certain  costs with respect to the existing  prospects.
     With respect to existing prospects and future prospects developed on leases
     acquired  prior to the Effective  Date and pursuant to the 1997  Agreement,
     any previously advanced leasehold and seismic costs that are recovered upon
     drilling  will be  allocated  80% to Comstock  and 20% to Bois d'Arc.  Upon
     execution of this Agreement, Comstock shall reimburse Bois d'Arc $1,226,491
     for costs  advanced by Bois d'Arc with  respect to certain  federal  leases
     acquired in May and June 2001 and the Fairfield Industries and Western GeCo
     seismic data acquired in June and July 2001.

3.   As part of the exploration  program  described  herein,  CRI shall issue to
     Bois d'Arc (or its  designees)  on August 1, 2001 and on each January 1 and
     July  1 (a  "Grant  Date")  of  each  calendar  year  thereafter  that  the
     exploration  program is in effect  warrants  exercisable  for shares of the
     common  stock,  $.50 par value  ("Common  Stock"),  of CRI.  The  number of
     warrants to be issued on each Grant Date shall equal the product of (i) the

                                       2



     total number of  Successful  Prospects  developed  pursuant to the terms of
     this Agreement  during the six (6) month period  immediately  preceding the
     applicable  Grant Date (or from the  Effective  Date  through July 31, 2001
     with  respect  to the  August 1, 2001 Grant Date and for the five (5) month
     period with  respect to the  January 1, 2002 Grant  Date) and (ii)  60,000;
     provided,  however,  that in no event  shall the number of  warrants  to be
     issued hereunder exceed 1,620,000 in the aggregate.  For purposes hereof, a
     prospect  shall be deemed a  "Successful  Prospect"  at such time  Comstock
     agrees to set  production  casing on the initial  test well or a substitute
     therefor with respect to the prospect (including existing prospects but for
     which warrants have not been issued  pursuant to the 1997  Agreement),  but
     excluding   successful   development  wells  drilled  and  completed  in  a
     previously  proven  reservoir.  Once a  prospect  is  deemed  a  Successful
     Prospect,  additional  warrants  will be earned if  additional  exploratory
     wells  are  drilled  on an  acquired  lease  and  Comstock  agrees  to  set
     production casing thereon.  The exercise price shall be the average closing
     price of the Common Stock, as reported on the New York Stock Exchange,  for
     the 30-calendar day period  immediately prior to the applicable Grant Date.
     Notwithstanding  the  foregoing,  with  respect to the August 1, 2001 Grant
     Date only,  Bois d'Arc may at its option chose either the 30-day average or
     the  closing  price of the Common  Stock on the date of  execution  of this
     Agreement as the exercise price for the warrants to be issued on such Grant
     Date. All unexercised  warrants  issued  hereunder shall terminate five (5)
     years  after  the  Expiration  Date  or the  earlier  termination  of  this
     Agreement.

4.   This Agreement  shall be for a period  commencing on the Effective Date and
     ending on December 31, 2006 (the "Expiration  Date").  Notwithstanding  the
     foregoing, Bois d'Arc shall have the right to terminate this Agreement upon
     a Change of Control (as defined  below).  Bois d'Arc may exercise its right
     to terminate by giving written notice to Comstock  within 30 days following
     such Change of Control.  In connection  with such a  termination,  Comstock
     will be assigned a 40% interest in any prospects not previously assigned to
     the  parties and will have no further  obligations  to make  advances.  For
     purposes  hereof,  a "Change of Control" shall mean (a) the  acquisition by
     any  person,  or two or more  persons  acting  in  concert,  of  beneficial
     ownership  (within the meaning of Rule 13d-3 of the Securities and Exchange
     Commission  under the Securities  Exchange Act of 1934) of more than 50% of
     the outstanding shares of voting stock of CRI or (b) the Board of Directors
     of CRI shall not  consist of a majority of the  directors  in office on the
     date hereof or such other directors as are recommended by a majority of the
     Board of Directors in office on the date hereof.

5.   If  Comstock  fails  to  fund a  minimum  of  $5,000,000  in the  aggregate
     hereunder for the  acquisition of seismic data within  forty-five (45) days
     of receipt of invoices  from Bois d'Arc for such  expenditures,  Bois d'Arc
     shall  have the  right  upon  thirty  (30)  days  prior  written  notice to
     terminate this Agreement.  Upon such termination,  Bois d'Arc shall have no
     further  obligations to Comstock hereunder other than to submit to Comstock
     prospects on previously acquired leaseholds in accordance with Section 1(b)
     above. For purposes of computing  Comstock's  obligation under this Section
     5, all amounts funded since the Effective Date shall be taken into account.

6.   Bois  d'Arc,  Laufer  and  Blackie  agree that they will not,  directly  or
     indirectly,  develop any  properties  in the Region other than  pursuant to
     this  Agreement  (or the 1997  Agreement),  unless  Comstock  elects not to
     participate with Bois d'Arc as provided herein.

                                       3




7.   This  Agreement  is  not  intended  to  create  a  partnership  or  similar
     relationship  between  Comstock  and Bois  d'Arc.  Except  as  specifically
     provided  herein,  no party  shall  have the  authority  to enter  into any
     agreement  on behalf of the other party  without such other  party's  prior
     written approval.

8.   If any  provision  of this  Agreement  is held to be  illegal,  invalid  or
     unenforceable,  the legality,  validity and enforceability of the remaining
     provisions hereof shall not be affected thereby.

9.   This  Agreement and the  transactions  contemplated  between Bois d'Arc and
     Comstock  relating to the subject  matter hereof and  supersedes  all prior
     agreements,   written  or  oral,  including  without  limitation  the  1997
     Agreement with the effective date of the  termination of the 1997 Agreement
     being the Effective Date.

10.  This  Agreement  shall  not be  amended  unless  in  writing  signed by all
     parties.

11.  This  Agreement  shall be  binding  upon and  inure to the  benefit  of the
     parties  hereto  and  their  respective   successors,   assigns  and  legal
     representatives.  No  party  shall  assign  this  Agreement  or any  rights
     hereunder   without  the  prior   written   consent  of  the  other  party.
     Notwithstanding  the  foregoing,  Bois d'Arc shall have the right to assign
     this  Agreement  and all  rights  and  obligations  hereunder  to an entity
     controlled by Laufer and Blackie.  For purposes hereof,  an entity shall be
     controlled  by Laufer and  Blackie if Laufer and Blackie  own,  directly or
     indirectly, in the aggregate 100% of the ownership interest in such entity.

12.  This  Agreement  may be  executed in  counterparts,  each of which shall be
     deemed an original and together shall constitute one instrument.

13.  Each party  agrees to perform,  execute  and  deliver  any such  additional
     documents  as may  reasonably  be  requested  to  consummate  or effect the
     transactions contemplated hereby.

                                       4
