                           FORWARD-LOOKING STATEMENTS

     All statements  other than statements of historical  facts included in this
report, including without limitation, statements under "Business and Properties"
and "Management's  Discussion and Analysis of Financial Condition and Results of
Operations"  regarding  budgeted  capital  expenditures,  estimates  of oil  and
natural gas production,  the Company's financial  position,  oil and natural gas
reserve  estimates,  business strategy and other plans and objectives for future
operations, are forward-looking  statements.  Although the Company believes that
the expectations reflected in such forward-looking statements are reasonable, it
can give no assurance  that such  expectations  will prove to have been correct.
There are numerous uncertainties inherent in estimating quantities of proved oil
and natural gas reserves and in projecting future rates of production and timing
of  development  expenditures,  including many factors beyond the control of the
Company.  Reserve engineering is a subjective process of estimating  underground
accumulations  of oil and  natural  gas that cannot be measured in an exact way,
and the  accuracy  of any  reserve  estimate  is a  function  of the  quality of
available data and of engineering and geological interpretation and judgment. As
a result,  estimates made by different engineers often vary from one another. In
addition,  results of drilling, testing and production subsequent to the date of
an estimate  may justify  revisions  of such  estimate  and such  revisions,  if
significant, would change the schedule of any further production and development
drilling.  Accordingly,  reserve  estimates  are  generally  different  from the
quantities of oil and gas that are  ultimately  recovered.  All  forward-looking
statements  in this  report are  expressly  qualified  in their  entirety by the
cautionary statements in this paragraph.

                                   DEFINITIONS

     The following are  abbreviations  and definitions of terms commonly used in
the oil and gas industry and this report.  Natural gas equivalents and crude oil
equivalents are determined using the ratio of six Mcf to one Bbl.

     "Bbl" means a barrel of 42 U.S. gallons of oil.

     "Bcf" means one billion cubic feet of natural gas.

     "Bcfe" means one billion cubic feet of natural gas equivalent.

     "Cash Margin per Mcfe" means the equivalent price per Mcfe less oil and gas
operating expenses per Mcfe and general and administrative expenses per Mcfe.

     "Completion"  means  the  installation  of  permanent   equipment  for  the
production of oil or gas.

     "Condensate" means a hydrocarbon  mixture that becomes liquid and separates
from natural gas when the gas is produced and is similar to crude oil.

     "Development well" means a well drilled within the proved area of an oil or
gas reservoir to the depth of a stratigraphic horizon known to be productive.

     "Dry hole" means a well found to be incapable of producing  hydrocarbons in
sufficient quantities such that proceeds from the sale of such production exceed
production expenses and taxes.

     "Exploratory  well" means a well drilled to find and produce oil or natural
gas reserves not classified as proved,  to find a new productive  reservoir in a
field  previously  found  to be  productive  of oil or  natural  gas in  another
reservoir or to extend a known reservoir.

                                       2
<PAGE>

     "Gross"  when used with respect to acres or wells,  production  or reserves
refers  to the  total  acres or wells in which the  Company  or other  specified
person has a working interest.

     "MBbls" means one thousand barrels of oil.

     "MMBbls" means one million barrels of oil.

     "Mcf" means one thousand cubic feet of natural gas.

     "Mcfe" means thousand cubic feet of natural gas equivalent.

     "MMcf" means one million cubic feet of natural gas.

     "MMcfe" means one million cubic feet of natural gas equivalent.

     "Net" when used with  respect to acres or wells,  refers to gross  acres of
wells multiplied,  in each case, by the percentage working interest owned by the
Company.

     "Net  production"  means  production  that is  owned  by the  Company  less
royalties and production due others.

     "Oil" means crude oil or condensate.

     "Operator" means the individual or company responsible for the exploration,
development, and production of an oil or gas well or lease.

     "Present  Value of Proved  Reserves"  means the present  value of estimated
future  revenues  to  be  generated  from  the  production  of  proved  reserves
calculated in accordance with the Securities and Exchange Commission guidelines,
net of estimated production and future development costs, using prices and costs
as of the date of estimation without future escalation, without giving effect to
non-property related expenses such as general and administrative  expenses, debt
service, future income tax expense and depreciation, depletion and amortization,
and discounted using an annual discount rate of 10%.

     "Proved  developed  reserves"  means  reserves  that can be  expected to be
recovered through existing wells with existing  equipment and operating methods.
Additional oil and gas expected to be obtained  through the application of fluid
injection or other improved  recovery  techniques for  supplementing the natural
forces and mechanisms of primary recovery will be included as "proved  developed
reserves"  only after  testing by a pilot  project or after the  operation of an
installed  program has confirmed  through  production  response  that  increased
recovery will be achieved.

     "Proved reserves" means the estimated quantities of crude oil, natural gas,
and natural gas liquids which  geological and engineering  data demonstrate with
reasonable  certainty to be  recoverable  in future years from known  reservoirs
under existing economic and operating  conditions,  i.e., prices and costs as of
the date the  estimate  is made.  Prices  include  consideration  of  changes in
existing  prices  provided  only  by  contractual   arrangements,   but  not  on
escalations based upon future conditions.

       (i)  Reservoirs  are  considered  proved  if  economic  producibility  is
     supported by either actual  production or conclusive  formation  tests. The
     area of a reservoir  considered proved includes (A) that portion delineated
     by drilling and defined by gas-oil and/or oil-water  contacts,  if any; and
     (B) the immediately  adjoining  portions not yet drilled,  but which can be
     reasonably  judged as  economically  productive  on the basis of  available
     geological  and  engineering  data. In the absence of  information on fluid
     contacts,  the lowest known structural  occurrence of hydrocarbons controls
     the lower proved limit of the reservoir.

                                       3
<PAGE>

       (ii) Reserves which can be produced  economically  through application of
     improved recovery  techniques (such as fluid injection) are included in the
     "proved"  classification when successful testing by a pilot project, or the
     operation of an installed  program in the reservoir,  provides  support for
     the engineering analysis on which the project or program was based.

       (iii) Estimates of proved reserves do not include the following:  (A) oil
     that  may  become   available  from  known  reservoirs  but  is  classified
     separately as "indicated additional reserves";  (B) crude oil, natural gas,
     and natural gas  liquids,  the  recovery of which is subject to  reasonable
     doubt because of uncertainty as to geology, reservoir  characteristics,  or
     economic factors; (C) crude oil, natural gas, and natural gas liquids, that
     may occur in  undrilled  prospects;  and (D) crude oil,  natural  gas,  and
     natural gas liquids, that may be recovered from oil shales, coal, gilsonite
     and other such resources.

     "Proved  undeveloped  reserves"  means  reserves  that are  expected  to be
recovered  from new wells on undrilled  acreage,  or from existing wells where a
relatively major expenditure is required for recompletion. Reserves on undrilled
acreage shall be limited to those drilling  units  offsetting  productive  units
that are  reasonably  certain of production  when drilled.  Proved  reserves for
other  undrilled  units can be claimed  only where it can be  demonstrated  with
certainty  that there is continuity of production  from the existing  productive
formation.  Under no  circumstances  should  estimates  for  proved  undeveloped
reserves  be  attributable  to any  acreage  for which an  application  of fluid
injection or other  improved  recovery  technique is  contemplated,  unless such
techniques  have been proved  effective  by actual  tests in the area and in the
same reservoir.

     "Recompletion" means the completion for production of an existing well bore
in another formation from that in which the well has been previously completed.

     "Reserve life" means the calculation  derived by dividing year-end reserves
by total production in that year.

     "Reserve  replacement" means the calculation  derived by dividing additions
to reserves from acquisitions, extensions, discoveries and revisions of previous
estimates in a year by total production in that year.

     "Royalty" means an interest in an oil and gas lease that gives the owner of
the  interest the right to receive a portion of the  production  from the leased
acreage (or of the proceeds of the sale thereof), but generally does not require
the owner to pay any portion of the cost of drilling or  operating  the wells on
the leased acreage.  Royalties may be either  landowner's  royalties,  which are
reserved by the owner of the leased acreage at the time the lease is granted, or
overriding royalties, which are usually reserved by an owner of the leasehold in
connection with a transfer to a subsequent owner.

     "3-D   seismic"   means  an  advanced   technology   method  of   detecting
accumulations  of  hydrocarbons  identified by the collection and measurement of
the  intensity  and  timing of sound  waves  transmitted  into the earth as they
reflect back to the surface.

     "Working interest" means an interest in an oil and gas lease that gives the
owner of the  interest  the  right to drill for and  produce  oil and gas on the
leased  acreage and  requires  the owner to pay a share of the costs of drilling
and production  operations.  The share of production to which a working interest
owner is  entitled  will  always be  smaller  than the  share of costs  that the
working  interest owner is required to bear,  with the balance of the production
accruing to the owners of  royalties.  For example,  the owner of a 100% working
interest in a lease  burdened  only by a  landowner's  royalty of 12.5% would be
required  to pay 100% of the  costs of a well but  would be  entitled  to retain
87.5% of the production.

     "Workover"  means  operations  on a  producing  well to restore or increase
production.

                                     PART I

ITEMS 1. AND 2. BUSINESS AND PROPERTIES

     Comstock Resources, Inc. (together with its subsidiaries,  the "Company" or
"Comstock")  is an  independent  energy  company  engaged  in  the  acquisition,
development,  production and exploration of oil and natural gas properties.  The
Company has an oil and natural gas reserve base which is entirely focused in the
Gulf of  Mexico,  Southeast  Texas  and East  Texas/  North  Louisiana  regions.
Approximately  43% of the  Company's oil and natural gas reserves are located in
the  Gulf of  Mexico,  26% in  Southeast  Texas  and 31% in  East  Texas/  North
Louisiana.  Due to this focus,  Comstock has  accumulated  significant  geologic
knowledge,  technical  expertise and industry  relationships  in these  regions.
Additionally,  the Company has significant operating control over its properties
and  operates  83% of its Present  Value of Proved  Reserves as of December  31,
1998.  Comstock has compiled a high quality reserve base that is 67% natural gas
and 76% proved  developed on a Bcfe basis.  The Company has estimated proved oil
and natural gas reserves of 371.9 Bcfe with an estimated Present Value of Proved
Reserves of $305.3 million as of December 31, 1998.

     Comstock  has  achieved   substantial  growth  in  oil  and  gas  reserves,
production and revenues over the last five years. The Company's estimated proved
oil and natural gas reserves have  increased at a compounded  annual growth rate
of 32%  from  123.6  Bcfe at the end of 1994 to  371.9  Bcfe at the end of 1998.
Average net daily production has increased at a compounded annual growth rate of
51%  from  22.2  MMcfe  per day in 1994 to  115.5  MMcfe  per day in  1998.  The
Company's  oil and gas revenues  have  increased  from $16.9  million in 1994 to
$93.0 million in 1998.

     While  its   historical   growth  has  been   primarily   attributable   to
acquisitions,  during 1998 Comstock  focused on the exploitation and development
of its properties through  development  drilling,  workovers,  recompletions and
exploration.  The Company believes it has a significant inventory of development
and  exploration  prospects  and  increased  its  spending  on  exploration  and
development  activities  from $2.1 million in 1994 to $64.6  million in 1998. In
1998,  Comstock  drilled  30  development  wells  (18.2  net) of  which  25 were
successful  (14.7 net) and 14  exploratory  wells (7.2 net) of which  eight were
successful (4.3 net).

     Over the past five years,  the Company has been able to lower lifting costs
and general and administrative expenses per unit of production,  concurrent with
increases in  production,  through  strict  control over  operations  and costs.
Comstock's  lifting costs per Mcfe have decreased from $0.75 in 1994 to $0.59 in
1998.  Comstock's  general and  administrative  expenses per Mcfe have decreased
from  $0.19  in 1994 to  $0.04  in 1998.  Operated  wells  represent  83% of the
Company's  Present  Value of Proved  Reserves as of  December  31,  1998,  which
enables  Comstock to  effectively  control costs and expenses and the timing and
method  of  exploration  and   development  of  its  properties.   Additionally,
Comstock's geographic focus allows it to manage its asset base with a relatively
small number of employees.

Business Strategy

     The  Company's  strategy  is to  increase  cash flow and net asset value by
exploiting  its  reserves,   pursuing   selective   exploration   opportunities,
maintaining  a low  cost  structure  and  acquiring  oil and gas  properties  at
attractive costs.

   Exploit Existing Reserves

     The Company  seeks to maximize the value of its  properties  by  increasing
production and recoverable  reserves through active  workover,  recompletion and
exploitation  activities.  The Company utilizes  advanced  industry  technology,
including 3-D seismic  data,  improved  logging tools and formation  stimulation

                                       5

techniques. During 1998, the Company spent $20.4 million to drill 30 development
wells (18.2 net), of which 25 wells (14.7 net) were  successful,  representing a
success rate of 83%. In addition,  the Company spent approximately $10.2 million
for recompletion and workover  activity during 1998. The Company has budgeted up
to $26.0 million in 1999 for development drilling and installation of production
facilities. Comstock's level of spending on development drilling in 1999 will be
principally dependent on improvement to existing oil and gas prices.

   Pursue Selective Exploration Opportunities

     The Company  pursues  selective  exploration  activities to find additional
reserves on its undeveloped  acreage.  In 1998, the Company spent  approximately
$30.4 million to drill 14 exploratory wells (7.2 net), of which eight wells (4.3
net) were  successful,  representing  a success  rate of 53%.  The  Company  has
budgeted up to $10.0 million in 1999 for  exploration  activities  which will be
focused on the Gulf of Mexico region and based on drilling 3-D seismic generated
prospects. These prospects include those acquired from Bois d' Arc Resources and
certain of its affiliates and working  interest  partners,  and those  prospects
generated under the joint exploration program with Bois d' Arc Resources and its
principals ("Bois d' Arc") entered into in December 1997 under which the Company
and Bois d' Arc jointly  explore for prospects in the Gulf of Mexico Region (the
"Bois d' Arc Exploration  Venture").  Under the Bois d' Arc Exploration Venture,
Bois d' Arc is responsible for identifying  potential  prospects and the parties
jointly acquire 3-D seismic data and leasehold acreage,  the costs for which are
shared 80% by the Company and 20% by Bois d' Arc.  With  respect to any prospect
in which the Company elects to participate in drilling,  the Company acquires up
to 33% working interest and recovers any disproportionate  seismic and leasehold
costs previously incurred. The Company issued to Bois d' Arc warrants to acquire
up to 1,000,000  shares of the  Company's  common stock at an exercise  price of
$14.00  per share as part of the  venture.  The  warrants  vest in 50,000  share
increments based on the success of an initial test well on a prospect.

   Maintain Low Cost Structure

     The Company seeks to increase cash flow by carefully  controlling operating
costs and general and administrative  expenses. The Company targets acquisitions
that possess,  among other  characteristics,  low per unit operating  costs.  In
addition,  the  Company  has been able to  reduce  per unit  operating  costs by
eliminating  unnecessary  field and  corporate  overhead  costs and by divesting
properties  that  have  high  lifting  costs  with  little  future   development
potential.  Through  these  efforts,  the Company's  general and  administrative
expenses and average oil and gas operating  costs per Mcfe have  decreased  from
$0.19 and  $0.75,  respectively,  in 1994 to $0.04 and $0.59,  respectively,  in
1998.

     In addition,  the Company  prefers to operate the  properties  it acquires,
allowing it to further control  operating  costs,  exercise greater control over
the timing and plans for future  development,  the level of drilling and lifting
costs,  and the  marketing of  production.  The Company  operates 366 of the 580
wells in which  it owns an  interest  which  comprise  approximately  83% of its
Present Value of Proved Reserves as of December 31, 1998.

   Acquire High Quality Properties at Attractive Costs

     The Company has a successful track record of increasing its oil and natural
gas reserves through opportunistic acquisitions.  Since 1991, Comstock has added
482.4 Bcfe of proved oil and  natural gas  reserves  from 18  acquisitions  at a
total cost of $411.9 million,  or $0.85 per Mcfe. The acquisitions were acquired
at 63% of their  Present Value of Proved  Reserves in the year the  acquisitions
were completed.  The Company's three largest  acquisitions to date have been its
acquisition of offshore Gulf of Mexico  properties  from Bois d' Arc and certain
of its  affiliates  and working  interest  partners in December  1997 for $200.9

                                       6

million  (the "Bois  d'Arc  Acquisition"),  its  acquisition  of Black Stone Oil
Company and interests in the Double A Wells field in Southeast Texas in May 1996
for  $100.4  million  (the  "Black  Stone  Acquisition")  and  its  purchase  of
properties  from  Sonat  Inc.  in  July  1995  for  $48.1  million  (the  "Sonat
Acquisition").  The Company applies strict economic and reserve risk criteria in
evaluating  acquisitions and targets properties in its core operating areas with
established  production  and  low  operating  costs  that  also  have  potential
opportunities  to increase  production  and  reserves  through  exploration  and
exploitation activities.

Primary Operating Areas

     The Company's activities are concentrated in three primary operating areas:
Gulf of Mexico,  Southeast Texas, and East Texas/ North Louisiana. The following

    Gulf of Mexico

     The Company's largest operating region includes properties located offshore
of  Louisiana in state and federal  waters of the Gulf of Mexico,  and in fields
along the Texas and  Louisiana  Gulf Coast.  The Company  owns  interests in 121
producing wells (71.1 net) in 11 field areas,  the largest of which are the Ship
Shoal area (Ship Shoal  Blocks 66, 67, 68, 69 and South Pelto Block 1), the Main
Pass area  (Main Pass  Blocks 21 and 25),  Bay  Marchand  Blocks 4 and 5 and the
South  Timbalier/  South Pelto area (South  Timbalier  Blocks 11,16,  34, 50 and
South Pelto  Blocks 5 and 15.) The Company has 159.5 Bcfe of oil and natural gas
reserves in the Gulf of Mexico region with a Present Value of Proved Reserves of
$137.7  million as of December  31, 1998.  The Company  operates 47 of the wells
(46.1 net) that it owns in this region.  The Company acquired a large percentage
of its reserves in the region in the Bois d' Arc  Acquisition.  Production  from
the region  averaged  17.5 MMcf of natural gas per day and 5,229  barrels of oil

                                       7

per day during 1998.  The Company  spent $35.7 million in this region in 1998 to
drill two  development  wells (1.4 net) and to drill 13  exploratory  wells (6.7
net). In 1999, the Company plans to spend $2.0 million for production facilities
at Bay Marchand  and South  Timbalier/  South Pelto and up to $12.0  million for
development drilling and up to $10.0 million for exploration  activities in this
region.

   Ship Shoal

     The Ship Shoal area is located  in  Louisiana  state  waters and in federal
waters,  offshore  of  Terrebonne  Parish  and  near  the  state/federal  waters
boundary.  The Company  became the operator of its  properties in this area as a
result of the Bois d' Arc  Acquisition  and owns a 99% to 100% working  interest
and operates these  properties  except for its properties in Ship Shoal Block 69
in which the Company has a 25% working interest. In the Ship Shoal area, oil and
natural gas are produced  from numerous  Miocene sands  occurring at depths from
5,800 feet to 13,500 feet, and in water depths from 10 to 40 feet. The Company's
Ship Shoal area has estimated proved reserves of 104.0 Bcfe (28% of total proved
reserves)  with a  Present  Value of  Proved  Reserves  of $99.8  million  as of
December 31, 1998. The Company owns interests in 33 wells (23.9 net) in the Ship
Shoal area, which averaged 12.8 MMcf of natural gas per day and 4,342 barrels of
oil per day during 1998.

     In 1998 the Company  drilled five wells (5.0 net), four  exploratory  wells
and one development well in the Ship Shoal area. Three of the exploration  wells
were successful and one was a dry hole. The three  successful  wells were placed
on  production  in November  and  December  1998.  The  Company has  temporarily
abandoned the development well as it was unable to successfully complete it.

   South Timbalier/ South Pelto

     The Company  owns  working  interests  ranging from 25% to 33% in Louisiana
state  waters and in federal  waters in the South  Timbalier/  South  Pelto area
located  offshore of Terrebonne  and Lafourche  Parishes in water depths ranging
from 20 to 60 feet.  Oil and natural gas are  produced  from  numerous  sands of
Pliocene to Upper Miocene age, at depths  ranging from 2,000 to 12,000 feet. The
Company has  drilled  three  successful  wells in the area since  beginning  its
exploration  program  with Bois d' Arc in 1998.  These wells should be placed on
production from common facilities which are expected to be completed by mid-year
1999. The Company also acquired a 33% working  interest in seven producing wells
as  well as  production  facilities  in  this  area in  1998.  The  Company  has
identified six exploration prospects and one proved undeveloped location in this
area using 3-D seismic,  targeting the Upper  Miocene sands  occurring at depths
from  10,000 to 12,000  feet.  The  Company has  estimated  proved net  reserves
totaling 11.7 Bcfe (3% of total proved reserves) in this area as of December 31,
1998.

   Bay Marchand

     The Company owns a 22.5% working  interest in Louisiana state leases in the
Bay Marchand area, located offshore of Lafourche Parish in 12 feet of water. The
Company has drilled three successful wells in its exploration  program with Bois
d' Arc since its inception in early 1998.  The Company has estimated  proved net
reserves  totaling 8.1 Bcfe (2% of total proved  reserves) at Bay Marchand as of
December  31,  1998.  Production  from these  wells  should  begin in the second
quarter of 1999 pending the  acquisition  of production  facilities  for the new
wells.  The  properties  are located on the west flank of the Bay Marchand  salt
dome in a highly prolific oil and natural gas producing region.  Producing zones
in this area are Upper to Middle  Miocene in age,  highly porous and  permeable,
and  occur at  depths  ranging  from  9,000 to  14,500  feet.  The  Company  has
identified  three  additional  exploration  prospects  in this  area,  using 3-D
seismic data.

Southeast Texas

     Approximately  26% (96.2 Bcfe) of the Company's proved reserves are located
in Southeast  Texas where the Company owns interests in 32 producing wells (12.2
net) and operates 24 of these wells.  Reserves in Southeast  Texas represent 29%
of the  Company's  Present  Value of Proved  Reserves as of December  31,  1998.
Production  rates from the area  averaged  28.3 MMcf of natural  gas per day and
1,532 barrels of oil per day during 1998.

     Substantially  all of the reserves in this region are in the Double A Wells
field area in Polk  County,  Texas.  The Double A Wells  field is the  Company's
second largest field area with total estimated proved reserves of 94.0 Bcfe (25%
of total proved reserves) which have a Present Value of Proved Reserves of $86.9
million as of December  31,  1998.  The Company  acquired  its  interests in the
Double A Wells  field in May 1996 in the  Black  Stone  Acquisition.  Net  daily
production  averaged  1,463  barrels of oil per day and 27.4 MMcf of natural gas
during 1998.  These wells  typically  produce from the Woodbine  formation at an
average  depth of 14,300 feet.  The Company has an average  working  interest in
this area of 37% and its  leasehold  position at December 31, 1998  consisted of
21,225 acres (7,863 net). During 1998, the Company successfully  recompleted two
wells in this  field and is in the  process of  acquiring  3-D  seismic  data on
25,000 acres in this area.  The Company has  budgeted  $2.5 million to drill two
development wells (0.6 net) in the Double A Wells field in 1999.

East Texas/ North Louisiana

     Approximately 31% (115.5 Bcfe) of the Company's proved reserves are located
in East  Texas and North  Louisiana  where the  Company  owns  interests  in 401
producing  wells  (225.2 net) in 18 field areas and  operates 276 of these wells
(199.5  net).  The largest of the  Company's  field areas in this region are the
Beckville,  Logansport,  Waskom and Box Church  fields.  Reserves  in the region
represented 26% of the Company's Present Value of Proved Reserves as of December
31, 1998.  Production from this region averaged 27.1 MMcf of natural gas per day
and 246 barrels of oil per day during 1998. The Company's largest acquisition in
this region was the Sonat Acquisition in July 1995. Since this acquisition,  the
Company  has  focused on  increasing  production  through  infill  drilling  and
recompletions.  Most of the reserves in this area  produce  from the  Cretaceous
aged  Travis  Peak/Hosston   formation  and  the  Jurassic  aged  Cotton  Valley
formation.  The total  thickness  of these  formations  range from 2,000 feet to
4,000 feet of sand and shale  sequences  in the East  Texas  Basin and the North
Louisiana  Salt Basin,  at depths  ranging from 6,000 feet to 10,500  feet.  The
Company  believes that success in these  formations  can be enhanced by applying
new hydraulic fracturing and completion  techniques,  magnetic resonance imaging
(MRI) logging tools and infill drilling. In 1998 the Company spent $14.5 million
to drill 29 wells  (17.3  net) and plans to spend up to $9.5  million in 1999 to
drill 16 development wells (10.5 net).

   Beckville

     The Company's  properties in the Beckville field, located in Panola County,
Texas, represented approximately 8% (28.1 Bcfe) of the Company's proved reserves
as of December  31, 1998.  The Company  operates 54 wells in this field and owns
interests in seven additional wells. The Company has an average working interest
of 72% in this field. During 1998, the production  attributable to the Company's
interest from this field  averaged 4.3 MMcf of natural gas and 23 barrels of oil
per day. The Beckville field produces from the Cotton Valley formation at depths
ranging from 9,000 to 10,000 feet.  The Company  drilled nine wells (6.2 net) in
1998 at a cost of $6.2  million and has budgeted up to $4.5 million to drill six
development wells (4.6 net) in 1999.

   Logansport

     The  Logansport  field  produces  from  multiple  pay zones in the  Hosston
formation  at an average  depth of 8,000  feet and is located in DeSoto  Parish,
Louisiana.  The Company's  proved reserves of 22.4 Bcfe in the Logansport  field
represented approximately 6% of the Company's proved reserves as of December 31,
1998.  The  Company  operates  72 wells in this field and owns  interests  in 32
additional  wells. The Company's  average working interest in this field is 50%.
During 1998, production attributable to the Company's interest averaged 7.1 MMcf
of natural gas and 28 barrels of oil per day. The Company  spent $3.4 million to
drill nine wells (4.4 net)  during 1998 and has  budgeted up to $2.0  million to
drill six development wells in 1999 (3.2 net).

   Waskom

     The  Waskom  field,  located in  Harrison  and  Panola  Counties  in Texas,
represented  approximately 4% (14.9 Bcfe) of the Company's proved reserves as of
December  31,  1998.  The  Company  operates  58  wells in this  field  and owns
interests in 38 additional wells. The Company's average working interest in this
field is 49%. During 1998,  production  attributable  to the Company's  interest
averaged 2.3 MMcf of natural gas and 32 barrels of oil per day. The Waskom field
produces from the Cotton Valley formation at depths ranging from 9,000 to 10,000
feet.

   Box Church

     The  Company's  properties  in the Box Church  field,  located in Limestone
County, Texas, represented  approximately 3% (11.9 Bcfe) of the Company's proved
reserves as of December 31, 1998. The Company  operates nine wells in this field
with an average working interest of 86%. During 1998, production attributable to
the Company's  interest  from this field  averaged 1.3 MMcf of natural gas and 2
barrels of oil per day. The Box Church  field  produces  from the Cotton  Valley
formation  at depths  ranging from 10,200 to 10,500  feet.  The Company  drilled
three wells (3.7 net) in 1998 at a cost of $2.4  million and has  budgeted up to
$1.6 million to drill two development wells (1.9 net) in 1999.

Acquisition Activities

   Acquisition Strategy

     The  Company  has  concentrated  its  acquisition  activity  in the Gulf of
Mexico,  Southeast  Texas  and East  Texas/  North  Louisiana  regions.  Using a
strategy that capitalizes on management's  strong knowledge of and experience in
these regions, the Company seeks to selectively pursue acquisition opportunities
where the Company  can  evaluate  the assets to be  acquired in detail  prior to
completion  of  the  transaction.  The  Company  evaluates  a  large  number  of
prospective  properties  according  to  certain  internal  criteria,   including
established  production and the properties'  future  development and exploration
potential,  low  operating  costs  and the  ability  for the  Company  to obtain
operating control.  The Company believes that due to the current  environment of
depressed  commodity  prices,  the  industry  will  continue to  consolidate  as
companies look to divest oil and gas  properties.  As a result,  the Company may
have   opportunities  to  make  acquisitions  at  favorable  prices,   including
attractive acquisitions outside its core operating areas.

</TABLE>

     In 1998 the  Company's  only  acquisition  was a purchase  of  acreage  and
production  facilities at South Timbalier Blocks 34 and 50 and South Pelto Block
15 located offshore of Louisiana in the Gulf of Mexico.

     Of the 18 property  acquisitions  completed by the Company since 1991, four
acquisitions  described below account for 83% of the total  acquisition cost and
total reserves acquired.

     Bois d' Arc  Acquisition.  In December 1997, the Company  acquired  working
interests in certain producing offshore Louisiana oil and gas properties as well
as   interests  in   undeveloped   offshore  oil  and  natural  gas  leases  for
approximately  $200.9 million from Bois d' Arc and certain of its affiliates and
working interest partners. The Company acquired interests in 43 wells (29.6 net)
and eight separate  production  complexes located in the Gulf of Mexico offshore
of Plaquemines and Terrebonne  Parishes,  Louisiana.  The  acquisition  included
interests in the Louisiana state and federal  offshore areas of Main Pass Blocks
21 and 25,  Ship Shoal  Blocks 66,  67, 68 and 69 and South  Pelto  Block 1. The
Company  also  acquired  interests  in  seven  undrilled  prospects  which  were
delineated by 3-D seismic data. The net proved reserves  acquired were estimated
at 14.3 MMBbls of oil and 29.4 Bcf of natural gas.  Approximately  $30.2 million
of the purchase price was attributed to the undrilled prospects and $1.0 million
was attributed to other assets.

     Black Stone  Acquisition.  In May 1996,  the Company  acquired  100% of the
capital  stock of Black  Stone  Oil  Company  and  interests  in  producing  and
undeveloped  oil and gas  properties  located  in  Southeast  Texas  for  $100.4
million.  The Company acquired  interests in 19 wells (7.7 net) that are located
in the Double A Wells field in Polk County, Texas and is the operator of most of
the wells in the field.  The net proved reserves  acquired were estimated at 5.9
MMBbls of oil and 100.4 Bcf of natural gas.

     Sonat Acquisition. In July 1995, the Company purchased interests in certain
producing oil and gas properties  located in East Texas and North Louisiana from
Sonat Inc. for $48.1 million.  The Company  acquired  interests in 319 producing
wells  (188.0  net).  The  acquisition  included  interests  in  the  Beckville,
Logansport,  Waskom,  Blocker,  Longwood  and  Simsboro  fields.  The net proved
reserves  acquired were  estimated at 0.8 MMBbls of oil and 104.7 Bcf of natural
gas.

     Stanford  Acquisition.  In November  1993,  the Company  acquired  Stanford
Offshore  Energy,  Inc.  ("Stanford")  through  a  merger  with a  wholly  owned
subsidiary.  The  Stanford  stockholders  were issued an  aggregate of 1,760,000
shares of common  stock of the  Company in the merger with a total value of $6.2
million and the Company assumed  approximately  $16.5 million of indebtedness of
Stanford.  Stanford  had  interests  in 107  producing  wells (58.8 net) located
primarily in the Gulf of Mexico region.  Major properties  acquired include West
Cameron  Blocks  238,  248 and 249,  the East White  Point field and the Redmond
Creek field.  The net proved  reserves  acquired were estimated at 1.0 MMBbls of
oil and 17.8 Bcf of natural gas.

     There are numerous uncertainties inherent in estimating oil and natural gas
reserves and their  values,  including  many  factors  beyond the control of the
producer.  The reserve data set forth above represents  estimates only.  Reserve
engineering is a subjective process of estimating  underground  accumulations of
oil and natural gas that cannot be measured in an exact manner.  The accuracy of
any  reserve  estimate is a function  of the  quality of  available  data and of
engineering and geological  interpretation and judgment. As a result,  estimates
of different engineers may vary. In addition,  estimates of reserves are subject
to revision based on the results of drilling,  testing and production subsequent
to the date of such estimate. Accordingly, reserve estimates are often different
from the quantities of oil and gas reserves that are ultimately recovered.

     In general,  the volume of production  from oil and natural gas  properties
declines as reserves  are  depleted.  Except to the extent the Company  acquires
properties  containing  proved reserves or conducts  successful  exploration and
development  activities,  the proved  reserves  of the Company  will  decline as
reserves are produced.  The Company's  future oil and natural gas production is,
therefore,  highly  dependent  upon its level of success in acquiring or finding
additional reserves.

     The Company's  average price  received for crude oil production on December
31, 1997 was $17.24 per Bbl.  This price  declined to $10.55 per Bbl on December
31, 1998.  The Company's  average price  received for natural gas  production on
December  31,  1997 was $2.64 per Mcf.  This price  declined to $2.21 per Mcf on
December  31,  1998.  Further  declines in the price of crude oil or natural gas
could have an adverse effect on the Company's  Present Value of Proved Reserves,
which in turn  could  adversely  affect  borrowing  capacity  and the  Company's
ability to obtain  additional  capital and the  Company's  financial  condition,
revenues, profitability and cash flows from operations.

     Title to the  Company's  oil and  natural  gas  properties  is  subject  to
royalty, overriding royalty, carried and other similar interests and contractual
arrangements customary in the oil and gas industry,  liens incident to operating
agreements,  current taxes not yet due, and other minor encumbrances. All of the
Company's oil and natural gas  properties  are pledged as  collateral  under the
Company's bank credit facility. As is customary in the oil and gas industry, the
Company  is  generally  able to retain its  ownership  interest  in  undeveloped
acreage by production of existing wells, by drilling  activity which establishes
commercial  reserves  sufficient  to  maintain  the lease or by payment of delay
rentals.

Markets and Customers

     The market for oil and  natural  gas  produced  by the  Company  depends on
factors  beyond its control,  including  the extent of domestic  production  and
imports of oil and  natural  gas,  the  proximity  and  capacity  of natural gas
pipelines and other transportation  facilities,  demand for oil and natural gas,
the  marketing  of  competitive  fuels  and the  effects  of state  and  federal
regulation.  The oil and gas industry  also  competes  with other  industries in
supplying  the  energy  and fuel  requirements  of  industrial,  commercial  and
individual consumers.

     Substantially all of the Company's natural gas production is sold either on
the spot natural gas market on a month-to-month  basis at prevailing spot market
prices or under long-term  contracts based on current spot market gas prices.  A
portion of the natural gas production from the Company's Double A Wells field is
sold under a long-term  contract to Houston  Pipeline  Company,  a subsidiary of
Enron  Corporation  ("HPL").  The agreement with HPL expires on October 31, 2000
with pricing  based on a percentage of spot gas prices for natural gas delivered
to the  Houston  Ship  Channel.  Total  gas sales in 1998 to HPL  accounted  for
approximately  17% of the Company's 1998 oil and gas sales.  Gas production from
the Company's  offshore  properties at the Ship Shoal and Main Pass areas, which
represented  12% of the  Company's  1998  oil and  gas  sales,  is sold  under a
short-term contract based on spot market gas prices to H & N Gas, Ltd.

     All of the  Company's  oil  production  is sold at the well  site at posted
field  prices tied to the spot oil  markets.  Sales of oil  production  from the
Company's Ship Shoal and Main Pass offshore  properties to Gulfmark Energy, Inc,
accounted for 25% of the Company's 1998 oil and gas sales.

Competition

     The oil and gas industry is highly  competitive.  Competitors include major
oil companies,  other independent energy companies, and individual producers and
operators,  many of which have  financial  resources,  personnel and  facilities
substantially  greater  than those of the  Company.  The Company  faces  intense
competition for the acquisition of oil and natural gas properties.

Regulation

     The  Company's  operations  are  regulated  by  certain  federal  and state
agencies.  In particular,  oil and natural gas production and related operations
are or have been subject to price controls, taxes and other laws relating to the
oil and natural gas industry.  The Company  cannot predict how existing laws and
regulations may be interpreted by enforcement agencies or court rulings, whether
additional laws and regulations will be adopted,  or the effect such changes may
have on its business or financial condition.

     Sales of  natural  gas by the  Company  are not  regulated  and are made at
market  prices.  However,  the Federal  Energy  Regulatory  Commission  ("FERC")
regulates interstate and certain intrastate natural gas transportation rates and
service  conditions,  which affect the  marketing of natural gas produced by the
Company,  as well as the  revenues  received  by the  Company  for sales of such

                                       14
<PAGE>

production. Since the mid-1980s, FERC has issued a series of orders, culminating
in Order  Nos.  636,  636-A and 636-B  ("Order  636"),  that have  significantly
altered  the  marketing  and   transportation  of  gas.  Order  636  mandated  a
fundamental  restructuring  of  interstate  pipeline  sales  and  transportation
service,  including  the  unbundling  by  interstate  pipelines  of  the  sales,
transportation,  storage and other  components of the city-gate  sales  services
such  pipelines  previously  performed.  One of FERC's  purposes  in issuing the
orders  was to  increase  competition  within  all  phases  of the  natural  gas
industry.  Generally,  Order 636 has  eliminated  or  substantially  reduced the
interstate  pipelines'  traditional  role as wholesalers of natural gas, and has
substantially increased competition and volatility in natural gas markets.

     Sales of oil and natural gas liquids by the Company are not  regulated  and
are made at market prices. The price the Company receives from the sale of these
products is affected by the cost of transporting the products to market.

     The  Company's  oil and natural  gas  exploration,  production  and related
operations  are  subject  to  extensive  rules and  regulations  promulgated  by
federal,  state and  local  agencies.  Failure  to  comply  with such  rules and
regulations can result in substantial  penalties.  The regulatory  burden on the
oil and gas industry  increases the Company's cost of doing business and affects
its profitability.  Because such rules and regulations are frequently amended or
reinterpreted,  the  Company is unable to predict  the future  cost or impact of
complying with such laws.

     The states of Texas and Louisiana require permits for drilling  operations,
drilling bonds and the filing of reports concerning  operations and impose other
requirements  relating to the  exploration  and production of oil and gas. These
states  also have  statutes  or  regulations  addressing  conservation  matters,
including  provisions  for the  unitization  or pooling of oil and  natural  gas
properties,  the  establishment  of maximum rates of production from oil and gas
wells and the regulation of spacing, plugging and abandonment of such wells. The
statutes and  regulations  of certain states limit the rate at which oil and gas
can be produced from the Company's properties.

     The  Company  is  required  to  comply  with  various   federal  and  state
regulations regarding plugging and abandonment of oil and natural gas wells. The
Company provides reserves for the estimated costs of plugging and abandoning its
wells, to the extent such costs exceed the estimated salvage value of the wells,
on a unit of production basis.

     Environmental

     Various  federal,  state  and  local  laws and  regulations  governing  the
discharge  of  materials  into the  environment,  or  otherwise  relating to the
protection  of  the  environment,   health  and  safety,  affect  the  Company's
operations and costs. These laws and regulations  sometimes require governmental
authorization  before  conducting  certain  activities,  limit or prohibit other
activities  because of protected  areas or species,  create the  possibility  of
substantial   liabilities  for  pollution  related  to  Company   operations  or
properties,  and  provide  penalties  for  noncompliance.   In  particular,  the
Company's drilling and production operations,  its activities in connection with
storage and transportation of crude oil and other liquid  hydrocarbons,  and its
use of facilities for treating,  processing or otherwise  handling  hydrocarbons
and  related   exploration  and  production  wastes  are  subject  to  stringent
environmental  regulation.  As with the  industry  in general,  compliance  with
existing and  anticipated  regulations  increases the Company's  overall cost of
business.  While these regulations affect the Company's capital expenditures and
earnings,  the  Company  believes  that  such  regulations  do  not  affect  its
competitive  position in the  industry  because its  competitors  are  similarly
affected by environmental  regulatory programs.  Environmental  regulations have
historically been subject to frequent change and, therefore,  the Company cannot
predict with certainty the future costs or other future impacts of environmental
regulations on its future  operations.  A discharge of hydrocarbons or hazardous

                                       15
<PAGE>


substances  into the  environment  could  subject  the  Company  to  substantial
expense, including the cost to comply with applicable regulations that require a
response to the discharge, such as containment or cleanup, claims by neighboring
landowners or other third parties for personal injury,  property damage or their
response costs and penalties  assessed,  or other claims  sought,  by regulatory
agencies for response cost or for natural resource damages.

     The  following  are examples of some  environmental  laws that  potentially
impact the Company and its operations.

     Water.  The Oil  Pollution  Act  ("OPA")  was  enacted  in 1990 and  amends
provisions  of the Federal  Water  Pollution  Control Act of 1972  ("FWPCA") and
other  statutes as they pertain to the  prevention  of and response to major oil
spills.  The OPA subjects owners of facilities to strict,  joint and potentially
unlimited  liability for removal costs and certain other  consequences of an oil
spill along shorelines or that enters navigable  waters.  In the event of an oil
spill  into such  waters,  substantial  liabilities  could be  imposed  upon the
Company.  Recent  regulations  developed  under OPA require  companies  that own
offshore  facilities,  including the Company, to demonstrate oil spill financial
responsibility  for removal costs and damage caused by oil discharge.  States in
which the Company  operates  have also enacted  similar  laws.  Regulations  are
currently  being  developed  under the OPA and similar  state laws that may also
impose additional regulatory burdens on the Company.

     The FWPCA imposes  restrictions and strict controls regarding the discharge
of produced  waters,  other oil and gas wastes,  any form of pollutant,  and, in
some instances,  storm water runoff, into waters of the United States. The FWPCA
provides for civil,  criminal and administrative  penalties for any unauthorized
discharges and, along with the OPA, imposes substantial  potential liability for
the costs of removal,  remediation  or damages  resulting  from an  unauthorized
discharge.  State laws for the control of water  pollution  also provide  civil,
criminal  and  administrative  penalties  and  liabilities  in  the  case  of an
unauthorized  discharge into state waters.  The cost of compliance  with the OPA
and the FWPCA have not historically  been material to the Company's  operations,
but there can be no  assurance  that  changes in  federal,  state or local water
pollution  control programs will not materially  adversely affect the Company in
the future.  Although no  assurances  can be given,  the Company  believes  that
compliance  with existing  permits and compliance  with  foreseeable  new permit
requirements will not have a material adverse effect on the Company's  financial
condition or results of operations.

     Air Emissions. Amendments to the Federal Clean Air Act enacted in 1990 (the
"1990 CAA Amendments") require or will require most industrial operations in the
United  States  to incur  capital  expenditures  in order to meet air  emissions
control standards developed by the United States Environmental Protection Agency
("EPA") and state environmental  agencies.  The 1990 CAA Amendments impose a new
operating permit on major sources,  and several of the Company's  facilities may
require permits under this new program. Although no assurances can be given, the
Company  believes  implementation  of the  1990 CAA  Amendments  will not have a
material  adverse  effect on the  Company's  financial  condition  or results of
operations.

     Solid  Waste.  The Company  generates  non-hazardous  solid wastes that are
subject to the  requirements of the Federal  Resource  Conservation and Recovery
Act ("RCRA") and comparable state statutes.  The EPA and the states in which the
Company operates are considering the adoption of stricter disposal standards for
the type of non-hazardous wastes generated by the Company. RCRA also governs the
generation,  management,  and  disposal of  hazardous  wastes.  At present,  the
Company  is not  required  to  comply  with a  substantial  portion  of the RCRA
requirements  because the Company's  operations  generate minimal  quantities of
hazardous wastes.  However,  it is possible that additional wastes,  which could
include wastes currently generated during the Company's operations, could in the
future be designated as "hazardous wastes." Hazardous wastes are subject to more

                                       16

rigorous and costly disposal and management  requirements than are non-hazardous
wastes.  Such  changes  in the  regulations  may  result in  additional  capital
expenditures or operating expenses by the Company.

     Superfund.  The Comprehensive  Environmental  Response,  Compensation,  and
Liability Act ("CERCLA"), also known as "Superfund",  imposes liability, without
regard to fault or the  legality  of the  original  act,  on certain  classes of
persons in  connection  with the  release of a  "hazardous  substance"  into the
environment.  These  persons  include the current  owner or operator of any site
where a release  historically  occurred and companies  that disposed or arranged
for the  disposal of the  hazardous  substances  found at the site.  CERCLA also
authorizes the EPA and, in some  instances,  third parties to act in response to
threats to the public health or the  environment and to seek to recover from the
responsible  classes  of  persons  the costs  they  incur.  In the course of its
ordinary  operations,  the Company  may have  managed  substances  that may fall
within CERCLA's definition of a "hazardous  substance."  Therefore,  the Company
may be jointly and  severally  liable  under CERCLA for all or part of the costs
required  to clean up sites where the  Company  disposed of or arranged  for the
disposal of these  substances.  This potential  liability  extends to properties
that the Company  previously  owned or operated,  as well as to properties owned
and operated by others at which disposal of the Company's  hazardous  substances
occurred.

     The  Company  may also  fall into the  category  of the  "current  owner or
operator." The Company  currently owns or leases  numerous  properties  that for
many years have been used for the  exploration  and  production  of oil and gas.
Although the Company believes it has utilized  operating and disposal  practices
that were standard in the industry at the time, hydrocarbons or other wastes may
have been  disposed of or  released  by the  Company on or under the  properties
owned or leased by the Company. In addition,  many of these properties have been
previously  owned or  operated  by third  parties  who may have  disposed  of or
released  hydrocarbons  or other  wastes at these  properties.  Under CERCLA and
analogous  state laws, the Company could be subject to certain  liabilities  and
obligations,  such as being required to remove or remediate  previously disposed
wastes  (including wastes disposed of or released by prior owners or operators),
to clean up contaminated  property  (including  contaminated  groundwater) or to
perform remedial plugging operations to prevent future contamination.

covering 20,046 square feet in a building under construction.  The Company plans
to relocate its  corporate  headquarters  to the building in June 1999.  The new

ITEM 7.   MANAGEMENT'S  DISCUSSION  AND  ANALYSIS  OF  FINANCIAL  CONDITION  AND
          RESULTS OF OPERATIONS

Results of Operations

     General

     The Company's results of operations have been significantly affected by its
success in acquiring  producing oil and natural gas properties.  Fluctuations in
oil and natural gas prices have also influenced the Company's financial results.
Relatively minor movements in oil and natural gas prices can lead to a change in
the Company's  results of  operations  and cash flow and could have an impact on
the Company's  borrowing base under its bank credit facility.  Based on the 1998
operating  results,  a change in the average  natural gas price  realized by the
Company of $0.10 per Mcf would result in a change in net income  attributable to
common stock of approximately $1.6 million,  or $0.07 per share. A change in the
average oil price  realized by the Company of $1.00 per barrel would result in a
change in net income  attributable to common stock of approximately $1.5 million
or $0.06 per share.

     The following table reflects certain summary operating data for the periods
presented:

     Year Ended December 31, 1998 Compared to Year Ended December 31, 1997

     Oil and gas sales increased $4.4 million (5%) to $93.0 million in 1998 from
$88.6 million in 1997. The increase is attributable to a 17% increase in natural
gas  production  and a 92%  increase  in oil  production,  offset  by 18%  lower
realized  natural gas prices and 35% lower realized oil prices.  The increase in
production is attributable to the Bois d' Arc Acquisition  completed in December
1997.

     Other income in 1998 decreased $430,000 (61%) to $274,000 from $704,000 for
1997. This decrease is attributable to a lower level of short-term cash deposits
outstanding  as well as the  termination  of  management  fee income  previously
received by the Company.

     Oil and gas operating  costs in 1998  increased $6.8 million (38%) to $24.7
million  from  $17.9  million  in 1997  due to the 36%  increase  in oil and gas
production  (on an equivalent  Mcf basis).  Oil and gas  operating  expenses per
equivalent Mcf produced increased $0.01 to $0.59 in 1998 from $0.58 in 1997.

                                       23
<PAGE>


     Exploration  expense  for  1998  was  $8.3  million  which  relates  to the
write-off of the six unsuccessful exploratory wells, as compared to $2.8 million
in 1997.

     Depreciation,  depletion and amortization  ("DD&A") increased $24.8 million
(94%) to $51.0 million from $26.2 million in 1997.  The increase is due to a 36%
increase  in oil and  natural  gas  production  and to higher  costs per unit of
amortization.  DD&A per  equivalent Mcf increased by $0.36 to $1.20 in 1998 from
$0.84 in 1997.  The increases in the DD&A rate relate to the higher costs of the
offshore properties acquired in the Bois d' Arc Acquisition.

     General and  administrative  expenses,  which are  reported net of overhead
reimbursements,  decreased  $1.1  million  (39%) to $1.6  million  in 1997.  The
decrease is attributable to an increase in overhead  reimbursements  received by
the  Company  in 1998  which was  greater  than the  increase  in the  Company's
overhead costs before reimbursements.

     Interest expense in 1998 increased $11.0 million (186%) to $17.0 million in
1998 from $5.9  million in 1997.  The  increase is related to a higher  level of
outstanding advances under the Company's bank credit facility due to the Bois d'
Arc Acquisition  completed in December 1997 as well as a higher average interest
rate on the Company's bank credit facility. The weighted average annual interest
rate under the  Company's  bank  credit  facility  increased  to 7.2% in 1998 as
compared to 6.6% in 1997. The increase in the rate was  attributable to a higher
utilization  of the  borrowing  base under the bank  credit  facility  after the
December 1997 acquisition.

     Due to the substantial  drop in oil and gas prices during 1998, the Company
provided an impairment of $17.0 million in 1998 of its oil and gas properties.

     The Company had a deferred tax benefit of $9.2  million for 1998,  using an
estimated tax rate of 35%.

     The net loss for the year ended  December  31, 1998 was $17.2  million,  as
compared to net income of $21.7  million,  in 1997.  Net loss per share for 1998
was $0.71 on weighted average shares  outstanding of 24.3 million as compared to
net  income  per  share of $0.85 for 1997 on  diluted  weighted  average  shares
outstanding of 26.0 million.

    Year Ended December 31, 1997 Compared to Year Ended December 31, 1996

     Oil and gas sales  increased  $19.6  million (28%) to $88.6 million in 1997
from $68.9  million  in 1996 due  primarily  to a 18%  increase  in natural  gas
production  and a 41% increase in oil  production as well as higher  natural gas
prices. The production  increases related primarily to production from the Black
Stone  Acquisition,  which  closed  in May 1996 and the Bois d' Arc  Acquisition
which closed in December 1997. The Company's average gas price increased 11% and
its average oil price decreased 11% during 1997 as compared to 1996.

     Other income increased  $111,000 (19%) to $704,000 in 1997 from $593,000 in
1996 due primarily to additional interest income earned on an increased level of
short-term cash deposits in 1997.

     Oil and gas operating expenses,  including production taxes, increased $4.1
million  (29%) to $17.9 million in 1997 from $13.8 million in 1996 due primarily
to the 23%  increase in oil and natural gas  production  (on an  equivalent  Mcf
basis)  resulting  primarily from the acquisitions in 1996 and 1997. Oil and gas
operating expenses per Mcfe produced increased 5% to $0.58 in 1997 from $0.55 in
1996 due primarily to increases in  production  taxes and ad valorem taxes which
were  related  to  the  higher  gas  prices   received  in  1997.

                                       24
<PAGE>


     General  and  administrative  expenses  increased  $429,000  (19%)  to $2.7
million in 1997 from $2.2 million in 1996.  This  increase  related to increased
general corporate  expenses  associated with the increased size of the Company's
operations.


     DD&A  increased  $8.0  million  (44%) to $26.2  million  in 1997 from $18.3
million in 1996 due to the 23% increase in oil and natural gas production (on an
Mcfe  basis).  Oil and gas  property  DD&A  per Mcfe  produced  of $0.84 in 1997
increased from $0.72 in 1996 due to the higher costs of the acquisitions  closed
in 1996 and 1997.

     Interest expense  decreased $4.2 million (41%) to $5.9 million in 1997 from
$10.1  million in 1996 due  primarily  to a decrease in the average  outstanding
advances under the Company's bank credit  facility.  The average annual interest
rate paid under the Company's  bank credit  facility  also  decreased to 6.6% in
1997 as compared to 8.1% in 1996.

     The Company  provided for income  taxes of $11.6  million for 1997 using an
estimated  effective  tax rate of 34%. No provision for income taxes was made in
1996 due to the  availability of previously  unrecognized tax assets relating to
net operating loss carryforwards.

     The Company  reported net income of $21.7 million,  after  preferred  stock
dividends of $410,000,  for the year ended  December 31, 1997,  as compared to a
net income of $24.1 million from  continuing  operations,  after preferred stock
dividends of $2.0 million,  for the year ended December 31, 1996. Net income per
share for 1997 was $0.85 on diluted  average shares  outstanding of 26.0 million
as  compared to $1.23 for 1996 on diluted  average  shares  outstanding  of 21.2
million.

Liquidity and Capital Resources

     Funding for the  Company's  activities  has  historically  been provided by
operating cash flow, debt and equity financings and asset dispositions.  In 1998
the  Company's  net cash flow  provided by operating  activities  totaled  $40.7
million ($50.2 million before  changes to other working  capital  accounts).  In
addition to operating  cash flow, the primary source of funds for the Company in
1998 was aggregate borrowings of $23.2 million.

     The Company's primary needs for capital,  in addition to funding of ongoing
operations,  relate to the  acquisition,  development and exploration of oil and
gas properties and the repayment of principal and interest on debt. In 1998, the
Company repaid $5.1 million of indebtedness and incurred capital expenditures of
$67.4 million primarily for development and exploration activities.

     The Company's annual capital expenditure activity is summarized as follows:

     The timing of most of the Company's  capital  expenditures is discretionary
with no material long-term capital expenditure  commitments.  Consequently,  the
Company  has a  significant  degree of  flexibility  to adjust the level of such
expenditures as circumstances  warrant.  The Company spent $11.5 million,  $33.6
million and $64.6 million on  development  and  exploration  activities in 1996,
1997  and  1998,  respectively.   The  Company  currently  anticipates  spending
approximately $10.0 to $36.0 million on development and exploration  projects in
1999.  The Company  intends to primarily use  internally  generated cash flow to
fund capital expenditures other than significant acquisitions and plans to limit
drilling  expenditures  in  1999 to  available  cash  flow  after  debt  service
payments.  Such debt  service  payments  are  expected to require a  substantial
amount of the Company's  available  cash flow unless oil and gas prices  improve
from  current  levels.  Without  an  improvement  in oil and gas  prices  or the
completion  of a debt or equity  financing,  the  Company's  1999 total  capital
expenditures will probably be limited to $10.0 million to $15.0 million.

     The Company does not have a specific  acquisition budget as a result of the
unpredictability of the timing and size of forthcoming  acquisition  activities.
The Company  intends to use borrowings  under its bank credit  facility or other
debt or  equity  financings  to the  extent  available  to  finance  significant
acquisitions.  The availability and attractiveness of these sources of financing
will depend upon a number of factors, some of which will relate to the financial
condition and  performance of the Company,  and some of which will be beyond the
Company's  control,  such as prevailing  interest rates,  oil and gas prices and
other market conditions.

     The Company's bank credit facility  consists of a $280.0 million  revolving
credit  commitment  provided  by a  syndicate  of ten  banks for which The First
National Bank of Chicago serves as administrative agent.  Indebtedness under the
bank credit facility is secured by  substantially  all of the Company's  assets.
The Company's  bank credit  facility is subject to borrowing  base  availability
which is generally  redetermined  semiannually  based on the banks' estimates of
the  future  net  cash  flows of the  Company's  oil and gas  properties.  As of
December 31, 1998,  the  borrowing  base was $280.0  million and is scheduled to
reduce to $240.0 million by December 31, 1999 and by an additional $20.0 million
by January 1, 2000. Such borrowing base may be affected from time to time by the
performance  of the Company's oil and gas  properties and changes in oil and gas
prices.  The  determination  of the  Company's  borrowing  base  is at the  sole
discretion of the  administrative  agent and the bank group.  The next scheduled
borrowing base redetermination will occur in April 1999; however, the bank group
can  request a  redetermination  at any time.  The  revolving  credit line bears
interest at the option of the Company at either (i) LIBOR plus 2.25% or (ii) the
"corporate  base rate" plus 1.25%.  The Company incurs a commitment fee of up to
0.5% per annum on the unused  portion of the borrowing  base. The average annual
interest rate as of December 31, 1998 of all outstanding  indebtedness under the
Company's bank credit facility was approximately 7.6%. The revolving credit line
matures on December 9, 2002 or such earlier  date as the Company may elect.  The
credit  facility  contains  covenants  which,  among other things,  restrict the
payment of cash dividends,  limit the amount of consolidated debt, and limit the
Company's ability to make certain loans,  capital  expenditures and investments.
Significant  financial  covenants include the maintenance of a current ratio, as
defined,  (0.75 to 1.0),  maintenance  of tangible  net worth  ($98.0  million),
maintenance  of an  interest  coverage  ratio  (2.5 to 1), and a  limitation  on
capital expenditures ($30.0 million).

     Based on the scheduled  borrowing base  reductions in 1999, the Company has
classified  $38.0  million  of the  amount  outstanding  under  its bank  credit
facility as a current  liability  at December  31,  1998.  The Company  plans to
reduce its  drilling  expenditures  in 1999 as compared to 1998 and utilize cash
flow generated from operations to reduce  outstanding  borrowings under the bank
credit facility. The Company believes that it will generate sufficient operating
cash flow during 1999 to reduce the  amounts  outstanding  under the bank credit
facility in accordance with the scheduled  reductions to the borrowing base. The
Company  intends to refinance  the  additional  $20.0  million  reduction to the

                                       26

<PAGE>

borrowing  base  scheduled to occur in January 2000 with a future debt or equity
financing  or to pay  down  such  debt  from  proceeds  from  sale  of  existing
properties. Management cannot be assured that such debt or equity financing will
be  available  for  the  Company  on  the  terms   acceptable  to  its  existing
shareholders  or that the banks will not require  additional  reductions  to the
borrowing base in the future.

     Based on  estimated  1999  oil and  natural  gas  production,  the  Company
estimates a change in the average  natural gas price  realized by the Company of
$0.10 per Mcf on unhedged  production  would  result in a change in cash flow of
approximately $1.5 million.  Also, the Company estimates a change in the average
oil price  realized by the  Company of $1.00 per barrel on  unhedged  production
would result in a change in cash flow of approximately $2.9 million.  If oil and
gas prices were to fall significantly  below current levels for the remainder of
1999 or if the banks were to further  reduce the Company's  borrowing  base, the
Company  would  likely  have to  complete  a debt or  equity  financing  or sell
selected  properties in order to meet the required 1999 scheduled  reductions to
its borrowing base.

     The Company may consider  additional debt or equity  financings in order to
provide liquidity and working capital for attractive  acquisition  opportunities
during the current  depressed  price  environment of the industry.  Based on the
current low oil and gas price  environment,  there can be no assurance that such
capital would be available with terms and  conditions  acceptable to the Company
or its existing stockholders.

Federal Taxation

     At December 31, 1998, the Company had federal income tax net operating loss
("NOL")  carryforwards of  approximately  $57.4 million.  The NOL  carryforwards
expire from 2005 through 2018. The value of these  carryforwards  depends on the
ability of the Company to  generate  federal  taxable  income and to utilize the
carryforwards to reduce such income.

Inflation

     In recent years inflation has not had a significant impact on the Company's
operations or financial condition.

Risk Management

     The Company's  market risk exposures  relate  primarily to commodity prices
and interest rates.  Therefore,  the Company  periodically  uses commodity price
swaps to hedge the impact of natural gas price  fluctuations  and uses  interest
rate swaps to hedge  interest  rates on floating rate debt. The Company does not
engage in  activities  using  complex  or highly  leveraged  instruments.  These
instruments  are  generally  put in place to limit risk of adverse  natural  gas
price or interest  rate  movements,  however,  these  instruments  usually limit
future  gains  from  favorable  natural  gas  price  or  lower  interest  rates.
Recognition  of  realized  gains or losses  are  deferred  until the  underlying
physical product is purchased or sold.  Unrealized gains or losses on derivative
financial  instruments are not recorded.  The cash flow impact of derivative and
other   financial   instruments  is  reflected  as  cash  flows  from  operating
activities.

     As a result of certain hedging  transactions  for natural gas the Company's
average realized natural gas price has been impacted as follows:

     As of December  31,  1998,  the Company  had no open  derivative  financial
instruments held for price risk management. Subsequent to December 31, 1998, the
Company entered into natural gas price swaps covering  10,480,000  MMBtus of its
natural gas  production  for March 1999 to October 1999 at 1,310,000  MMBtus per
month at a fixed index price of $1.81 (after basis adjustment), which represents
approximately 60% of the Company's estimated gas production for that period.

     The  table  below  provides  information  about  the  Company's  derivative
financial instruments that are sensitive to changes in interest rates, including
interest rate swaps and debt  obligations.  For interest  rate swaps,  the table
presents  notional  amounts and weighted  average  interest rates by contractual
maturity dates.  Notional amounts are used to calculate the contractual payments
to be exchanged under the contract. Weighted average variable rates are based on
implied forward rates in the yield curve as of December 31, 1998.

Year 2000

     "Year 2000," or the ability of computer systems to process dates with years
beyond 1999,  affects almost all companies and  organizations.  Computer systems
that are not Year 2000  compliant by January 1, 2000 may cause an adverse effect
to companies  and  organizations  that rely upon those  systems.  The Company is
assessing  and  correcting  the  potential  impact  of  problems  with  computer
software,  operating systems, and equipment containing computer processing chips
that are  unable  to  properly  process  dates  beyond  1999.  The  Company  has
outsourced its significant financial  information systems.  Based on information
received from the Company's providers, the Company is relying on assurances from
the providers that they are Year 2000 compliant.  The Company's costs related to
Year 2000 have not been  significant  and it  expects  future  costs will not be
material.

     Because the  Company  outsources  its  information  technology  systems and
software,  it believes that there is little risk  associated  with Year 2000 for
its information  systems.  The Company  believes that there is minimal risk with
embedded  technology  associated with its operations because it does not own any
significant gas processing plants or pipelines, nor does it have any significant
electronic field data capture systems on its wells.  However, the Company cannot
provide assurance that all significant third parties will achieve  compliance in
a timely  manner.  Such  failure to achieve Year 2000  compliance  could have an
adverse  effect  on the  Company's  operations  and cash  flow due to  potential
shut-in production or delay in drilling schedules. Although the Company does not
have a formal  contingency plan, it stands ready to switch from vendors that are
not Year 2000 compliant.

ITEM 8.  FINANCIAL STATEMENTS

     The  Consolidated  Financial  Statements for Comstock  Resources,  Inc. and
Subsidiaries are included on pages F-1 to F-19 of this report.

     The  financial  statements  have been  prepared  by the  management  of the
Company in conformity with generally accepted accounting principles.  Management
is responsible for the fairness and reliability of the financial  statements and
other  financial  data  included  in  this  report.  In the  preparation  of the
financial  statements,  it is necessary to make informed estimates and judgments
based on currently  available  information  on the effects of certain events and
transactions.

     The  Company  maintains  accounting  and other  controls  which  management
believes  provide  reasonable  assurance  that  financial  records are reliable,
assets  are  safeguarded,   and  that  transactions  are  properly  recorded  in
accordance with management's  authorizations.  However, limitations exist in any
system of  internal  control  based  upon the  recognition  that the cost of the
system should not exceed benefits derived.

     The Company's  independent  public  accountants,  Arthur  Andersen LLP, are
engaged  to audit the  financial  statements  of the  Company  and to express an
opinion thereon.  Their audit is conducted in accordance with generally accepted
auditing  standards to enable them to report  whether the  financial  statements
present fairly, in all material respects,  the financial position and results of
operations  of the Company in  accordance  with  generally  accepted  accounting
principles.

     The Audit  Committee of the Board of Directors of the Company,  composed of
three directors who are not employees,  meets  periodically with the independent
public accountants and management.  The independent public accountants have full
and free access to the Audit  Committee  to meet,  with and  without  management
being  present,  to  discuss  the  results of their  audits  and the  quality of
financial reporting.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS




To the Board of Directors and Stockholders
  of Comstock Resources, Inc.:

     We have audited the  accompanying  consolidated  balance sheets of Comstock
Resources,  Inc. (a Nevada corporation) and subsidiaries as of December 31, 1997
and 1998, and the related consolidated  statements of operations,  stockholders'
equity and cash flows for each of the three years in the period  ended  December
31, 1998.  These financial  statements are the  responsibility  of the Company's
management.  Our  responsibility  is to express  an  opinion on these  financial
statements based on our audits.

     We conducted  our audits in accordance  with  generally  accepted  auditing
standards.  Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement.  An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements.  An audit also includes
assessing the  accounting  principles  used and  significant  estimates  made by
management,  as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

     In our opinion,  the financial statements referred to above present fairly,
in all material respects, the financial position of Comstock Resources, Inc. and
subsidiaries  as of  December  31,  1997  and  1998,  and the  results  of their
operations  and their cash flows for each of the three years in the period ended
December 31, 1998, in conformity with generally accepted accounting principles.

                    COMSTOCK RESOURCES, INC. AND SUBSIDIARIES

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(1)  Business and Organization

     Comstock  Resources,   Inc.,  a  Nevada  corporation   (together  with  its
subsidiaries, the "Company"), was formed in 1919 as Comstock Tunnel and Drainage
Company. In 1987, the Company's name was changed to Comstock Resources, Inc. The
Company is primarily  engaged in the  acquisition,  development,  production and
exploration of oil and natural gas properties in the United States.

(2)  Significant Accounting Policies

     Principles of Consolidation

     The consolidated  financial  statements include the accounts of the Company
and its wholly owned  subsidiaries.  All significant  intercompany  accounts and
transactions have been eliminated in consolidation.

     Use of Estimates

     The  preparation  of financial  statements  in  conformity  with  generally
accepted  accounting  principles  requires  management  to  make  estimates  and
assumptions  that  affect the  reported  amounts of assets and  liabilities  and
disclosure of  contingent  assets and  liabilities  at the date of the financial
statements  and the  reported  amounts  of  revenues  and  expenses  during  the
reporting period. Actual results could differ from those estimates.

     Concentrations of Credit Risk

     Although the Company's cash equivalents and accounts receivable are exposed
to credit loss, the Company does not believe such risk to be  significant.  Cash
equivalents  are  high-grade,  short-term  securities,  placed with highly rated
financial  institutions.  Most of the Company's  accounts  receivable are from a
broad  and  diverse  group of oil and gas  companies  and,  accordingly,  do not
represent a significant credit risk.

     Oil and Gas Properties

     The Company follows the successful efforts method of accounting for its oil
and gas operations.  Under this method,  costs of productive wells,  development
dry  holes  and   productive   leases  are   capitalized   and  amortized  on  a
unit-of-production  basis  over the life of the  remaining  related  oil and gas
reserves.  Cost centers for amortization purposes are determined on a field area
basis. The estimated future costs of dismantlement,  restoration and abandonment
are accrued as part of  depreciation,  depletion  and  amortization  expense and
included in the accompanying  Consolidated  Balance Sheets as Reserve for Future
Abandonment Costs.

     Oil  and  gas  leasehold  costs  are  capitalized.  Unproved  oil  and  gas
properties with significant  acquisition costs are periodically assessed and any
impairment  in value is charged to  expense.  The costs of  unproved  properties
which are  determined to be  productive  are  transferred  to proved oil and gas
properties.  Exploratory expenses, including geological and geophysical expenses
and delay rentals for unevaluated oil and gas properties, are charged to expense
as incurred.  Exploratory  drilling costs are initially  capitalized as unproved
property but charged to expense if and when the well is  determined  not to have
found proved oil and gas reserves.

                                       F-7

<PAGE>



     In accordance with the Statement of Financial  Accounting Standards No. 121
("SFAS 121")  "Accounting for the Impairment of Long-Lived Assets and Long-Lived
Assets to Be Disposed  Of", the Company  assesses the need for an  impairment of
capitalized  costs of oil and gas properties on a property by property basis. If
an impairment is indicated  based on  undiscounted  expected  future cash flows,
then an impairment is recognized to the extent that net capitalized costs exceed
discounted  expected  future cash flows.  No impairment  was required in 1996 or
1997. Due to the substantial drop in oil and gas prices during 1998, the Company
provided an impairment of $17.0 million in 1998.

     Other Property and Equipment

     Other  property  and  equipment of the Company  consists  primarily of work
boats, a gas gathering system,  computer  equipment,  and furniture and fixtures
which are depreciated over estimated useful lives on a straight-line basis.

     Income Taxes

     Deferred  income taxes are provided to reflect the future tax  consequences
of  differences  between  the tax  basis of  assets  and  liabilities  and their
reported amounts in the financial statements using enacted tax rates.

     Earnings Per Share

     Basic  and  diluted  earnings  per  share  for  1996,  1997 and  1998  were
determined as follows:

     New Accounting Standard

     In June 1998, the Financial  Accounting Standards Board issued Statement of
Financial Accounting  Standards No. 133, "Accounting for Derivative  Instruments
and Hedging Activities" ("SFAS No. 133"). The Statement  establishes  accounting
and reporting  standards that are effective for the fiscal years beginning after
June 15, 1999 which require that every derivative  instrument (including certain
derivative  instruments  embedded in other contracts) be recorded in the balance
sheet as either an asset or liability  measured at its fair value. The Statement
requires that changes in the derivative's fair value be recognized  currently in
earnings unless specific hedge accounting criteria are met.

     The Company uses  derivatives to hedge  floating  interest rate and natural
gas price risks.  Such  derivatives  are reported at cost, if any, and gains and
losses on such  derivatives  are reported  when the hedged  transaction  occurs.
Accordingly,  the Company's  adoption of SFAS No. 133 will have an impact on the
reported  financial  position of the Company,  and although  such impact has not
been determined,  it is currently not believed to be material.  Adoption of SFAS
No.  133 should  have no  significant  impact on  reported  earnings,  but could
materially affect comprehensive income.

(3)  Acquisitions of Oil and Gas Properties

     On May 7,  1997,  the  Company  purchased  certain  producing  oil  and gas
properties located in the Lisbon field in Claiborne Parish,  Louisiana for a net
purchase price of $20.1 million.  The acquisition included interests in 13 wells
(7.1 net wells).

     On December 9, 1997,  the Company  acquired  interests in certain  offshore
Louisiana oil and gas properties as well as interests in undeveloped oil and gas
leases for $200.9 million from Bois d' Arc Resources ("Bois d' Arc") and certain
affiliates and working  interest  partners of Bois d' Arc. The Company  acquired
interests in 43 wells (29.6 net wells) and eight separate  production  complexes
located in the Gulf of Mexico offshore of Plaquemines  and Terrebonne  Parishes,
Louisiana. The acquisition included interests in the Louisiana state and federal
offshore  areas of Main Pass Blocks 21 and 25, Ship Shoal  Blocks 66, 67, 68 and
69 and South Pelto Block 1.  Approximately  $30.2 million of the purchase  price
was attributed to the undrilled prospects and $1.0 million of the purchase price
was attributed to other assets.

                                       F-9

<PAGE>


     The  acquisitions  were  accounted  for  utilizing  the purchase  method of
accounting.  The accompanying  consolidated statements of operations include the
results of operations from the acquired  properties  beginning on the dates that
the acquisitions  were closed.  The following table summarizes the unaudited pro
forma effect on the  Company's  consolidated  statements of operations as if the
acquisitions  consummated  in 1997 had been  closed on January  1, 1997.  Future
results may differ substantially from pro forma results due to changes in prices
received for oil and gas sold, production declines and other factors. Therefore,
the pro forma amounts should not be considered indicative of future operations.

(4)  Sales of Oil and Gas Properties

     The Company  sold certain oil and gas  properties  for  approximately  $9.0
million and $5.1 million in 1996 and 1997,  respectively.  The  properties  sold
were non-strategic assets to the Company.  Gains from the property sales of $1.4
million and $85,000 are included in the accompanying  Consolidated Statements of
Operations for 1996 and 1997, respectively.

     The  Company  has  a  $280.0  million  revolving  credit  facility  with  a
syndication  of ten banks in which The First  National Bank of Chicago serves as
administrative agent, (the "Bank Credit Facility"). As of December 31, 1998, the
Company  had  $278.0  million   outstanding  under  the  Bank  Credit  Facility.
Borrowings  under  the Bank  Credit  Facility  cannot  exceed a  borrowing  base
determined  semiannually  by the banks.  The borrowing base at December 31, 1998
was $280.0 million.  The borrowing base is scheduled to reduce to $240.0 million
by December 31, 1999 and will reduce by an  additional  $20.0 million by January
1,  2000.  The  determination  of the  Company's  borrowing  base is at the sole
discretion of the  administrative  agent and the bank group.  The next scheduled
borrowing base redetermination will occur in April 1999; however, the bank group
can request a redetermination  at any time.  Amounts  outstanding under the Bank
Credit  Facility bear  interest at a floating  rate based on The First  National
Bank of Chicago's base rate (as defined) plus 1.25% or, at the Company's option,
at a fixed rate for up to six months based on the London Interbank  Offered Rate
("LIBOR")  plus  2.25%.  As of  December  31,  1998,  the Company had placed the
outstanding  advances under the revolving credit facility under fixed rate loans
based on LIBOR at an average rate of approximately  7.6% per annum. In addition,
the  Company  incurs  a  commitment  fee of 0.5% on the  unused  portion  of the
borrowing base depending upon the  utilization of the available  borrowing base.
The Bank Credit  Facility  matures on December  9, 2002.  Significant  financial
covenants  under the Bank Credit  Facility  include the maintenance of a current
ratio,  as defined,  (0.75 to 1.0),  maintenance  of tangible  net worth  ($98.0
million), maintenance of an interest coverage ratio (2.5 to 1), and a limitation
on capital expenditures ($30.0 million).

     Based on the scheduled  borrowing base  reductions in 1999, the Company has
classified  $38.0  million  of the  amount  outstanding  under  the Bank  Credit
Facility as a current  liability  at December  31,  1998.  The Company  plans to
reduce its  drilling  expenditures  in 1999 as compared to 1998 and utilize cash
flow generated from operations to reduce  outstanding  borrowings under the Bank

                                      F-11

Credit Facility. The Company believes that it will generate sufficient operating
cash flow during 1999 to reduce the  amounts  outstanding  under the Bank Credit
Facility in accordance with the scheduled  reductions to the borrowing base. The
Company  intends to refinance  the  additional  $20.0  million  reduction to the
borrowing  base  scheduled to occur in January 2000 with a future debt or equity
financing  or to pay  down  such  debt  from  proceeds  from  sale  of  existing
properties. Management cannot be assured that such debt or equity financing will
be  available  for  the  Company  on  the  terms   acceptable  to  its  existing
shareholders  or that the banks will not require  additional  reductions  to the
borrowing base in the future.  If oil and gas prices were to fall  significantly
below  current  levels for the remainder of 1999 or if the banks were to further
reduce the Company's borrowing base, the Company would likely have to complete a
debt or  equity  financing  or sell  selected  properties  in  order to meet the
required 1999 scheduled reductions to its borrowing base.

(7)  Lease Commitments

     The Company rents office space under certain noncancellable leases. Minimum
future payments under the leases are as follows:

(8)  Stockholders' Equity

     Preferred Stock

     On January 7, 1994,  the  Company  sold  600,000  shares of its Series 1994
Convertible  Preferred  Stock,  $10  par  value  per  share  (the  "Series  1994
Preferred"),  in a private placement for $6.0 million. Dividends were payable at
the  quarterly  rate of  $0.225 on each  outstanding  share of the  Series  1994
Preferred (9% per annum of the par value). On September 16, 1996, the holders of
the  Series  1994  Preferred  converted  all of the  shares of the  Series  1994
Preferred into 1,500,000 shares of common stock of the Company.

     On July 22, 1994, the Company issued  1,000,000 shares of its 1994 Series B
Convertible  Preferred  Stock,  $10 par  value  per share  (the  "1994  Series B
Preferred"),  in connection with the repurchase of certain  production  payments
previously  conveyed by the Company to a major  natural gas  company.  Dividends
were payable at the quarterly rate of $0.15625 on each outstanding  share (6.25%
per  annum of the par  value).  On July  11,  1996,  the  Company  redeemed  the
1,000,000  shares of the 1994 Series B Preferred by issuing  2,000,000 shares of
common stock of the Company.

     On June 19,  1995,  the Company  sold  1,500,000  shares of its Series 1995
Convertible  Preferred  Stock,  $10  par  value  per  share  (the  "Series  1995
Preferred"), in a private placement for $15.0 million. Dividends were payable at
the quarterly rate of $0.225 on each outstanding  share (9% per annum of the par
value).  On  December  2, 1996,  holders of  793,677  shares of the Series  1995
Preferred converted their preferred shares into 1,511,761 shares of common stock
of the  Company.  On August 20, 1997,  the holders of the Series 1995  Preferred
converted  all of the  remaining  shares of the Series 1995  Preferred,  $10 par
value, into 1,345,373 shares of common stock of the Company.

     Common Stock

     Under a plan adopted by the Board of Directors,  non-employee directors can
elect to receive  shares of common stock valued at the then current market price
in payment of annual director and consulting  fees. Under this plan, the Company
issued  37,117,  9,256 and 39,678  shares of common  stock in 1996,  1997,  1998


                                      F-12

<PAGE>


respectively, in payment of fees aggregating $154,000, $113,000 and $263,000 for
1996,  1997 and 1998,  respectively.  Shares  issued in 1998  also  prepaid  the
director and consulting fees for 1999.

     Each of the Company's formerly outstanding  preferred stock series provided
that the  Company  could  issue  common  stock in lieu of cash  for  payment  of
quarterly  dividends.  The Company issued 249,453 shares of common stock in 1996
in payment of dividends on its preferred stock of $1,320,000.

     On December 2, 1996, the Company  completed a public  offering of 5,795,000
shares  of  common   stock  of  which   4,000,000   (4,869,250   including   the
over-allotment option which was exercised on December 12, 1996) shares were sold
by the  Company and  1,795,000  shares  were sold by certain  stockholders.  Net
proceeds to the Company,  after the  underwriting  discount and other  expenses,
were approximately  $57.0 million and were used to reduce indebtedness under the
Bank Credit Facility.

     On August 20, 1997, the Company  repurchased the 1,345,373 shares of common
stock held by former Series 1995 Preferred  stockholders at $12.00 per share for
an aggregate purchase price of $16.1 million.

     Options and warrants to purchase common stock of the Company were exercised
for 1,007,177  shares,  98,100 shares and 102,000 shares in 1996, 1997 and 1998,
respectively.   Such   exercises   yielded  net   proceeds  to  the  Company  of
approximately  $3.6  million,  $507,000  and  $288,000  in 1996,  1997 and 1998,
respectively.

     Stock Options and Warrants

     On July 16, 1991,  the Company's  stockholders  approved the 1991 Long-Term
Incentive Plan (the  "Incentive  Plan") for the Company's  management  including
officers,  directors and managerial employees. The Incentive Plan authorizes the
grant of  non-qualified  stock options and incentive stock options and the grant
of  restricted  stock to key  executives  of the Company.  On May 15, 1996,  the
Company's  stockholders  approved an amendment to the Incentive Plan  increasing
the shares to be awarded by  1,240,000.  As of December 31, 1998,  the Incentive
Plan provided for future  awards of stock options or restricted  stock grants of
up to 228,630 shares of common stock plus 10% of any future  issuances of common
stock.

     The following table  summarizes stock option activity during 1996, 1997 and
1998 under the Incentive Plan:

Financial  Accounting Standards No. 123 ("SFAS 123") "Accounting for Stock-Based
Compensation,"  the Company's net income and earnings per share from  continuing
operations would have been reduced to the following pro forma amounts:

                             Pro Forma         0.96         0.72

     Because the SFAS 123 method of  accounting  has not been applied to options
granted prior to January 1, 1995, the resulting pro forma  compensation cost may
not be representative of that to be expected in future years.

     The fair value of each option grant is estimated on the date of grant using
the  Black-Scholes  option  pricing  model with the following  weighted  average
assumptions  used for  grants in 1996,  1997,  and 1998,  respectively:  average
risk-free interest rates of 6.34, 6.33, and 5.30 percent; average expected lives
of 7.7, 7.3, and 8.2 years;  average expected  volatility  factors of 54.5, 51.9
and 58.8; and no dividend yield.  The estimated  weighted  average fair value of
options  to  purchase  one  share of common  stock  issued  under the  Company's
Incentive Plan was $6.20 in 1996, $7.45 in 1997, and $2.98 in 1998.

     The Company also has options  outstanding to purchase 220,530 common shares
at $5.00 per share at December 31, 1998 that were issued in  connection  with an
oil and gas property acquisition in 1994. These options expire in 1999.

     On  December  8, 1997,  the  Company  awarded  warrants  to  purchase up to
1,000,000  shares of the  Company's  common stock at $14.00 per share to Bois d'
Arc in  connection  with a five-year  joint  exploration  venture.  The warrants
become  exercisable  in  increments  of 50,000  shares upon the  election by the
Company to complete a  successful  exploration  well on a prospect  generated by
Bois  d'  Arc  under  the  joint  exploration  venture.  Warrants  which  become
exercisable under the exploration  venture expire on December 31, 2007. The fair
value of each  warrant to purchase one share of common stock is estimated at the
date of grant at $9.97 using the  Black-Scholes  option  pricing  model with the
following assumptions: risk-free interest rate of 6.35 percent; expected life of
10.1 years;  expected volatility factor of 51.9 percent;  and no dividend yield.
During 1998,  warrants to purchase  150,000 shares became vested.  The estimated
value of the  warrants  which  vested in 1998 of $1.5  million  was  included as
exploration costs for three successful wells under the exploration venture.

     Restricted Stock Grants

     Under the Incentive Plan, officers and managerial  employees of the Company
may be granted a right to receive  shares of the Company's  common stock without
cost to the employee.  The shares vest over a ten-year  period with credit given
for past service  rendered to the Company.  Restricted  stock grants for 330,000
shares have been  awarded  under the  Incentive  Plan.  As of December 31, 1998,
322,500 shares of such awards are vested.  A provision for the restricted  stock
grants is made ratably over the vesting period.  Compensation expense recognized
for restricted stock grants for the years ended December 31, 1996, 1997 and 1998
was $41,000, $15,000, and $7,000, respectively.

(9)  Significant Customers

     The Company had sales to one  purchaser  of crude oil which  accounted  for
17%, 17%, and 25% of the Company's  oil and gas sales in 1996,  1997,  and 1998,
respectively.  In 1996 and 1997,  the Company had one  purchaser  of natural gas
which  accounted  for 31% and 35%,  respectively,  of the  Company's oil and gas
sales. In 1998 the Company had two purchasers of natural gas which accounted for
17% and 12% of the Company's oil and gas sales.

     The tax effects of significant temporary  differences  representing the net
deferred tax liability at December 31, 1997 and 1998 were as follows:

     No income tax provision was recognized in 1996 due to the  availability  of
net operating loss  carryforwards  to offset any current or deferred  income tax
liabilities.

     The  difference  between  income taxes computed using the statutory rate of
35% and the Company's effective tax rate in 1997 and 1998 is as follows:

     The Company has net operating loss  carryforwards  of  approximately  $57.4
million as of December 31, 1998 for income tax reporting  purposes  which expire
in varying amounts from 2005 to 2018.


(11) Related Party Transactions

     The  Company  served  as  general  partner  of  Comstock  DR-II  Oil  & Gas
Acquisition Limited  Partnership  ("Comstock DR-II") until December 29, 1997. In
1996 and 1997,  the Company  received  management  fees from  Comstock  DR-II of
$87,000 and $40,000, respectively.


     From  August 1, 1995 to December  1, 1996,  the  Company  was the  managing
general partner and owned a 20.31% limited partner interest in Crosstex Pipeline
Partners,  Ltd.  ("Crosstex").  The Company sold its interest in connection with
the sale of its  third  party  natural  gas  marketing  operations  (see Note 13
"Discontinued Operations").  The Company received $82,000 in fees for management
and  construction  services  provided  to  Crosstex  in 1996 and was  reimbursed
$228,000 for direct expenses  incurred in connection  with managing  Crosstex in
1996.  The Company paid $477,000 to Crosstex for  transportation  of its natural
gas production in 1996.

(12) Risk Management

     The Company's  market risk exposures  relate  primarily to commodity prices
and interest rates.  Therefore,  the Company  periodically  uses commodity price
swaps to hedge the impact of natural gas price  fluctuations  and uses  interest
rate swaps to hedge  interest  rates on floating rate debt. The Company does not
engage in  activities  using  complex  or highly  leveraged  instruments.  These
instruments  are  generally  put in place to limit risk of adverse  natural  gas
price or interest  rate  movements,  however,  these  instruments  usually limit
future  gains  from  favorable  natural  gas  prices  or lower  interest  rates.
Recognition  of  realized  gains or losses  in the  Consolidated  Statements  of
Operations are deferred until the  underlying  physical  product is purchased or
sold.  Unrealized  gains or losses on derivative  financial  instruments are not
recorded.  The cash flow impact of derivative and other financial instruments is
reflected as cash flows from operating activities in the Consolidated Statements
of Cash Flows.

<PAGE>


     As a result of certain  hedging  transactions  for  natural gas the Company
realized the following gains and losses:



                               1996      1997      1998
                               ----      ----      ----

       Realized Losses         1,643      --         --


     As of  December  31,  1997 and 1998,  the  Company  had no open  derivative
financial instruments held for price risk management. Subsequent to December 31,
1998,  the Company  entered  into  natural gas price swaps  covering  10,480,000
MMBtus of its natural gas production for March 1999 to October 1999 at 1,310,000
MMBtus per month at a fixed index price of $1.81 (after basis adjustment).

     The Company entered into interest rate swap agreements in September 1998 to
hedge the impact of interest  rate changes on a portion of its  long-term  debt.
The notional amount of the swap agreements is $125.0 million and fixed the LIBOR
rate at an  average  rate of 5.1%  through  September  2000.  Gains  and  losses
attributable to the swap agreements are accounted for as a hedge. Gains from the
swap agreements  reduced  interest expense by $59,000 in 1998. The fair value of
the interest rate swaps as of December 31, 1998 was a liability of approximately
$95,000.

(13) Discontinued Operations

     In December  1996,  the Company sold its third party  natural gas marketing
operations and substantially all of its related gas gathering and gas processing
assets for approximately $3.0 million. The Company realized a $818,000 gain from
the sale.  The  Company's gas  gathering,  processing  and marketing  segment is
accounted  for  as  discontinued   operations  in  the  accompanying   financial
statements,  and accordingly,  the results of the gas gathering,  processing and
marketing  operations  as well as the gain on  disposal  are  segregated  in the
accompanying Consolidated Statements of Operations.

     Income for discontinued gas gathering,  processing and marketing operations
included  in the  Consolidated  Statements  of  Operations  for the  year  ended
December 31, 1996 is comprised of the following:

(15) Oil and Gas Reserves Information (Unaudited)

     The estimates of proved oil and gas reserves utilized in the preparation of
the financial  statements were estimated by independent  petroleum  engineers in
accordance with guidelines established by the Securities and Exchange Commission
and the Financial Accounting Standards Board, which require that reserve reports
be prepared under existing  economic and operating  conditions with no provision
for  price  and cost  escalation  except by  contractual  agreement.  All of the
Company's  reserves are located onshore in or offshore to the continental United
States.

     Future prices received for production and future production costs may vary,
perhaps  significantly,  from the prices and costs assumed for purposes of these
estimates.  There can be no assurance that the proved reserves will be developed
within the periods  indicated  or that  prices and costs will  remain  constant.
There can be no  assurance  that  actual  production  will  equal the  estimated
amounts used in the preparation of reserve  projections.  In accordance with the
Securities  and Exchange  Commission's  guidelines,  the  Company's  independent
petroleum  engineers'  estimates  of future net cash  flows  from the  Company's
proved  properties  and the present value thereof are made using oil and natural
gas  sales  prices in  effect  as of the  dates of such  estimates  and are held
constant  throughout  the  life  of  the  properties.  Average  prices  used  in
estimating  the future net cash  flows  were as  follows:  $17.24 and $10.55 per
barrel  of oil for 1997 and 1998,  respectively,  and $2.64 and $2.21 per Mcf of
natural gas for 1997 and 1998, respectively.

     There are  numerous  uncertainties  inherent in  estimating  quantities  of
proved  reserves  and in  projecting  future rates of  production  and timing of
development expenditures.  Oil and gas reserve engineering must be recognized as
a subjective process of estimating underground accumulations of oil and gas that
cannot be measured  in an exact way,  and  estimates  of other  engineers  might
differ  materially from those shown below.  The accuracy of any reserve estimate
is a function of the quality of available  data and  engineering  and geological
interpretation and judgment.  Results of drilling,  testing and production after
the date of the estimate may justify revisions.  Accordingly,  reserve estimates
are  often  materially  different  from the  quantities  of oil and gas that are
ultimately recovered. Reserve estimates are integral in management's analysis of
impairments  of oil and gas  properties  and the  calculation  of  depreciation,
depletion and amortization on those properties.

any time and from time to time from the  Effective  Date  until the  Termination
Date amounts equal to such Bank's Pro Rata Share of such  aggregate  Advances as
any Borrower  may from time to time  request,  provided  that no Advances may be

exceed the lesser of the Commitments or the Borrowing Base;  provided,  however,
that the aggregate principal amount of Letters of Credit outstanding at any time
shall not exceed $5,000,000.  Each Loan made hereunder shall be evidenced by the

<PAGE>

          (b) For  purposes of this  Agreement,  a Letter of Credit  Advance (i)
shall be deemed  outstanding in an amount equal to the sum of the maximum amount
available to be drawn under the related Letter of Credit on or after the date of
determination and on or before the stated expiry date thereof plus the amount of
any draws under such Letter of Credit that have not been  reimbursed as provided
in Section 3.3 and (ii) shall be deemed  outstanding  at all times on and before
such stated  expiry date or such earlier date on which all amounts  available to
be drawn under such Letter of Credit have been fully drawn, and thereafter until
all related reimbursement obligations have been paid pursuant to Section 3.3. As
provided in Section  3.3,  upon each payment made by the Agent in respect of any
draft or other demand for payment under any Letter of Credit,  the amount of any
Letter of Credit Advance outstanding  immediately prior to such payment shall be
automatically  reduced by the amount of each Loan deemed  advanced in respect of
the related reimbursement obligation of the Borrowers.

          (c) The  Borrowers  shall  have the right to  terminate  or reduce the
Commitments  at any time and from time to time,  provided that (i) the Borrowers
shall give notice of such  termination or reduction to the Agent  specifying the
amount  and  effective  date  thereof,   (ii)  each  partial  reduction  of  the
Commitments shall be in a minimum amount of $1,000,000 and in integral multiples
of  $1,000,000   and  shall  reduce  the   Commitments   of  all  of  the  Banks
proportionally in accordanc with the respective  Commitment amounts of each such
Bank,  (iii)  no such  termination  or  reduction,  either  in whole or part and
including without limitation any termination, shall be permitted with respect to
any  portion  of the  Commitments  as to which a request  for  Advances  is then
pending, and (iv) the Commitments may not be terminated if any Advances are then
outstanding  and may not be reduced below the principal  amount of Advances then
outstanding.  The Commitments or any portion thereo so terminated or reduced may
not be reinstated.  Any Borrower may request Advances without the consent of any
other  Borrower,  and  each  Borrower  consents  to and  approves  any  Advances
requested by any other Borrower.  The Advances  hereunder  replace the revolving
credit loans and letters of credit outstanding pursuant to Section 2.1(a) of the
Existing Credit Agreement and provide additional credit as described above.

          (d) This Agreement amends and restates the Existing Credit  Agreement,
and all Advances  and Letters of Credit  outstanding  under the Existing  Credit
Agreement shall  constitute  Advances and Letters of Credit under this Agreement
and all fees and other  obligations  accrued under the Existing Credit Agreement
will continue to accrue and be paid under this Agreement. As stated in the Notes
and the Consent and  Amendment  to Security  Documents,  the  Advances and other
obligations  pursuant  hereto are issued in  exchange  and  replacement  for the
Advances and other obligations under an Existing Credit Agreement,  shall not be
a novation or satisfaction  thereof and shall be entitled to the same collateral
with the same priority.

     SECTION 3. The Advances.

     3.1 Disbursement of Advances . (a) Borrowers shall give notice to the Agent
of each requested Advance in substantially  the form of Exhibit C hereto,  which
notice  given shall be received by the Agent not later than 10:00 a.m.  (Chicago
time), (i) three Business Days prior to the date such Advance is requested to be

Advance.  Each  such  notice  given  shall be  irrevocable  and  binding  on the
Borrowers,  any such notice must  specify  the  Advance  Date,  which shall be a
Business  Day,  the  aggregate  amount  of such  Advance,  the  Type of  Advance
selected,  in the case of any Eurodollar  Loan, the Eurodollar  Interest  Period

information  and documents with respect thereto as may be required by the Agent.
The Agent shall  provide  notice of such  requested  Advance to each Bank on the
same  Business Day such notice is received  from the  Borrowers.  Subject to the
terms and conditions of this Agreement,  the Agent shall, on the date any Letter
of Credit Advance is requested to be made, issue the related Letter of Credit on
behalf of the Banks for the account of the designated Borrower.  Notwithstanding
anything  herein to the  contrary,  the Agent may decline to issue any requested
Letter of Credit on the basis that the  beneficiary,  the purpose of issuance or
the terms or the  conditions  of drawing  are illegal or contrary to a policy of
the Agent.

                                      E-14
<PAGE>

          (b) Floating  Rate Loans shall  continue as Floating Rate Loans unless
and until such Floating Rate Loans are converted  into  Eurodollar  Loans.  Each
Eurodollar  Loan of any Type shall  continue as a  Eurodollar  Loan of such Type
until the end of the then  applicable  Interest Period  therefor,  at which time
such Eurodollar Loan shall be automatically  converted into a Floating Rate Loan
unless the Borrower shall have given the Agent a Conversion/Continuation  Notice
requestin that, at the end of such Interest Period,  such Eurodollar Loan either
continue  as a  Eurodollar  Loan for the same or another  Interest  Period or be
converted into a Loan of another Type.  Subject to the terms of Section 2.1, the
Borrower may elect from time to time to convert all or any part of a Loan of any
Type into any other Type or Types of a Loan; provided that any conversion of any
Eurodollar  Loan  shall be made on,  and only on,  the last day of the  Interest
Period applicable thereto. The Borrowers shall give the Agent irrevocable notice
(a "Conversion/Continuation   Notice")  of  each    conversion  of  a   Loan  or
continuation  of a Eurodollar  Loan not later than 10:00 a.m.  (Chicago time) at
least one Business  Day, in the case of a conversion  into a Floating Rate Loan,
or three Business Days, in the case of a conversion  into or  continuation  of a
Eurodollar Loan, prior to the date of the requested  conversion or continuation,
specifying:

               (i) the  requested  date,  which shall be a Business Day, of such
conversion or continuation,

               (ii) the  aggregate  amount  and Type of the Loan  which is to be
converted or continued, and

               (iii) the amount and  Type(s) of Loan(s)  into which such Loan is
to be  converted  or  continued  and,  in  the  case  of a  conversion  into  or
continuation  of  a  Eurodollar  Loan,  the  duration  of  the  Interest  Period
applicable thereto.

          (c)  Subject  to the  terms  and  conditions  of this  Agreement,  the
proceeds of such  requested  Loan shall be made  available  to the  Borrowers by
depositing the proceeds thereof, in immediately  available funds, on the Advance
Date for such Loan in an account  maintained  and designated by the Borrowers at
the principal  office of the Agent.  Each Bank, on the Advance Date of each such
Loan  shall  make  its Pro Rata  Share of such  Loan  available  in  immediately
available  funds at the principal  office of the Agent for  disbursement  to the
Borrowers.  Unless the Agent shall have  received  notice from any Bank prior to
the date of any  requested  Loan under this  Section 3.1 that such Bank will not
make  available  to the Agent such Bank's Pro Rata  Share,  the Agent may assume
that such Bank has made such share available to the Agent on the Advance Date of
such Loan in accordance with this Section 3.1(b). If and to the extent such Bank
shall not have so made such Pro Rata Share available to the Agent, the Agent may
(but shall not be obligated  to) make such amount  available to the Borrowers on
the relevant Advance Date, and such Bank agrees to pay to the Agent forthwith on
demand such amount  together with interest  thereon,  for each day from the date
such amount is made  available to the Borrowers by the Agent until the date such
amount is paid to the Agent,  at the Federal  Funds Rate. If such Bank shall pay
to the Agent such  amount,  such amount so paid shal  constitute  a Loan by such
Bank as a part of such borrowing for purposes of this Agreement.  The failure of
any Bank to make its Pro Rata  Share of any such  Loan  available  to the  Agent
shall not relieve any other Bank of its  obligations  to make  available its Pro
Rata Share of such Loan on the Advance  Date of such Loan,  but no Bank shall be
responsible  for failure of any other Bank to make such Pro Rata Share available
to the Agent on the Advance Date of any such Loan.

          (d) Each Bank may book its Loans at any Lending Installation  selected
by such Bank and may  change its  Lending  Installation  from time to time.  All
terms of this  Agreement  shall apply to any such Lending  Installation  and the
Notes  shall  be  deemed  held by each  Bank  for the  benefit  of such  Lending
Installation.  Each Bank may,  by written  or telex  notice to the Agent and the
Borrowers,  designate a Lending Installation through which Loans will be made by
it and for whose account Loan payments are to be made.

          (e)  Nothing  in this  Agreement  shall be  construed  to  require  or
authorize any Bank to issue any Letter of Credit,  it being  recognized that the
Agent has the sole obligation under this Agreement to issue Letters of Credit on

                                      E-15
<PAGE>

behalf of the Banks, and the Commitment of each Lender with respect to Letter of
Credit Advances is expressly  conditioned  upon the Agent's  performance of such
obligations.  Upon such issuance by the Agent, each Bank shall automatically and
unconditionally  acquire a risk participation  interest to the extent of its Pro
Rata Share in such Letter of Credit Advance based on its respective  Commitment.
If the Agent shall honor a draft or other  demand for payment  presented or made
under any Letter of Credit,  the Agent shall provide notice thereof to each Bank
on the date such draft or demand is  honored  unless  the  Borrowers  shall have
satisfied  their  reimbursement  obligation  under Section 3.3 by payment to the
Agent on such date.  Each Bank,  not later than the Business Day after the Agent
shall have given the notice specified in the previous  sentence,  shall make its
Pro  Rata  Share  of the  amount  paid by the  Agent  available  in  immediately
available  funds at the  principal  office of the Agent for the  account  of the
Agent.  If and to the extent such Bank shall not have made any required Pro Rata
Share  amount  available  to the  Agent or made its  portion  of Loan  available
pursuant to Section  3.3(a)(i),  such Bank and the Borrowers  severally agree to
pay to the Agent forthwith on demand such amount together with interest thereon,
for each day from the date such  amount was paid by the Agent  until such amount
is so made  available to the Agent at (i) the interest  rate then  applicable to
Floating  Rate Loans for such day in the case of the Borrowers and (ii) the rate
per  annum  equal  to the  Federal  Funds  Rate for the  first  five  days,  and
thereafter at the interest rate  applicable to Floating Rate Loans,  in the case
of any Bank. If such Bank shall pay such amount to the Agent  together with such
interest,  such amount so paid shall  constitute  a Loan by such Bank as part of
the Loans disbursed in respect of the reimbursement  obligation of the Borrowers
under  Section 3.3 for  purposes of this  Agreement.  The failure of any Bank to
make its Pro Rata Share of any such  amount paid by the Agent  available  to the
Agent shall not relieve any other Bank of its  obligation to make  available its
Pro Rata Shar of such amount,  but no Bank shall be  responsible  for failure of
any other Bank to make such Pro Rata Share available to the Agent.

     3.2 Conditions of Advances . The Banks and the Agent shall not be obligated
to make any Advance hereunder at any time unless:

the Floating  Rate for the account of the Banks in an amount equal to the amount
so paid by the Agent in respect of such draft or other  demand under such Letter
of Credit.  Such Loan shall be  disbursed,  and each Bank shall  advance its Pro
Rata Share  thereof,  notwithstanding  any failure to satisfy any conditions for
disbursement of any Loan set forth in Article III or any other condition and, to
the  extent  of the  Loan so  disbursed,  the  reimbursement  obligation  of the
Borrowers under this Section 3.3 shall be deemed satisfied;  provided,  however,
that  such  disbursement  shall  not be  deemed  to be a waiver  of any Event of
Default or Default, if any.

               (ii) If for any reason (including  without limitation as a result
of the occurrence of an Event of Default pursuant to Section  6.1(h)),  Floating
Rate Loans may not be made by the Banks as described in Section 3.3(a)(i),  then
(A) the Borrowers agree that each reimbursement  amount not paid pursuant to the
first sentence of Section  3.3(a)(i)  shall bear interest,  payable on demand by
the Agent, at the interest rate then applicable to Floating Rate Loans,  and (B)
effective on the date each such  Floating  Rate Loan would  otherwise  have been
made, each Bank severally agrees that it shall  unconditionally and irrevocably,
without regard to the occurrence of any Default or Event of Default,  in lieu of
a deemed  disbursement  of Loans,  to the extent of such  Bank's Pro Rata Share,
purchase a participating  interest in each reimbursement  amount. Each Bank will
immediately  transfer  to the  Agent,  in same  day  funds,  the  amount  of its
participation.  Each Bank  shall  share in  accordance  with its Pro Rata  Share
(calculated  by reference to the  Commitments)  in any  interest  which  accrues
thereon and in all repayments  thereof. If and to the extent that any Bank shall
not have so made the  amount of such  participating  interest  available  to the
Agent, such Bank and the Borrowers agree to pay to the Agent forthwith on demand
such amount together with interest thereon, for each day from the date of demand
by the Agent until the date such amount is paid to the Agent, at (x) in the case
of the Borrowers,  the interest rate then  applicable to Floating Rate Loans and
(y) in the case of such Bank,  the  Federal  Funds Rate for the first five days,
and thereafter the interest rate applicable to Floating Rate Loans.

          (b) The reimbursement  obligations of the Borrowers under this Section
3.3 shall be absolute,  unconditional  and  irrevocable and shall remain in full
force and effect  until all  obligations  of the  Borrowers to the Agent and the
Banks hereunder shall have been satisfied, and such obligations of the Borrowers
shall not be  affected,  modified or impaired  upon the  happening of any event,
including without limitation,  any of the following,  whether or not with notice
to, or the consent of, the Borrowers:

               (i) Any lack of  validity  or  enforceability  of any  Letter  of
Credit  or  any  documentation  relating  to  any  Letter  of  Credit  or to any
transaction  related in any way to such Letter of Credit (the  "Letter of Credit
Documents");

               (ii) Any  amendment,  modification,  waiver  or  consent,  or any
substitution,  exchange  or release of or failure  to perfect  any  interest  in
collateral or security, with respect to any of the Letter of Credit Documents.

               (iii) The existence of any claim, setoff,  defense or other right
which  the  Borrowers  may  have at any  time  against  any  beneficiary  or any
transferee of any Letter of Credit (or any persons or entities for whom any such
beneficiary or any such transferee may be acting),  the Agent or any Bank or any
other person or entity,  whether in connection  with any of the Letter of Credit
Documents,  the  transactions  contemplated  herein or therein or any  unrelated
transactions;

               (iv) Any draft or other statement or document presented under any
Letter of Credit proving to be forged,  fraudulent,  invalid or  insufficient in
any respect or any statement therein being untrue or inaccurate in any respect;

               (v) Payment by the Agent to the  beneficiary  under any Letter of
Credit against  presentation  of documents which do not comply with the terms of
the Letter of Credit,  including  failure of any documents to bear any reference
or adequate reference to such Letter of Credit;

               (vi)  Any  failure,  omission,  delay  or lack on the part of the
Agent or any Bank or any  party to any of the  Letter  of  Credit  Documents  to
enforce, assert or exercise any right, power or remedy conferred upon the Agent,
any Bank or any such party under this  Agreement  or any of the Letter of Credit
Documents,  or any other acts or omissions on the part of the Agent, any Bank or
any such party; or

               (vii) Any other event or circumstance  that would, in the absence
of this  clause,  result in the  release or  discharge  by  operation  of law or
otherwise the Borrowers from the  performance  or observance of any  obligation,
covenant or agreement  contained  in this Section 3.3. No setoff,  counterclaim,

                                      E-18

reduction or diminution  of any  obligation or any defense of any kind or nature
which the Borrowers  have or may have against the  beneficiary  of any Letter of
Credit shall be available  hereunder to the  Borrowers  against the Agent or any
Bank.  Nothing in this  Section  3.3 shall limit the  liability,  if any, of the
Borrowers to the Banks pursuant to Section 10.5(b).

     3.4.  Withholding  Tax Exemption.  At least five Business Days prior to the
first date on which  interest or fees are payable  hereunder  for the account of
any Bank, each Bank that is not incorporated under the laws of the United States
of  America,  or a state  thereof,  agrees  that it will  deliver to each of the
Borrowers  and the Agent two duly  completed  copies of United  States  Internal
Revenue  Service Form 1001 or 4224,  certifying in either case that such Bank is
entitled  to  receive  payments  under  this  Agreement  and the  Notes  without
deduction or withholding  of any United States  federal income taxes.  Each Bank
which so delivers a Form 1001 or 4224 further  undertakes  to deliver to each of
the Borrowers and the Agent two  additional  copies of such form (or a successor
form) on or before the date that such form expires (currently,  three successive
calendar  years for Form 1001 and one  calendar  year for Form  4224) or becomes
obsolete  or after the  occurrence  of an event  requiring  a change in the most
recent forms so delivered by it, and such  amendments  thereto or  extensions or
renewals  thereof as may be reasonably  requested by the Borrowers or the Agent,
in each case  certifying  that such Bank is entitled to receive  payments  under
this  Agreement and the Notes  without  deduction or  withholding  of any United
States federal income taxes,  unless an event (including  without limitation any
change in treaty,  law or regulation) has occurred prior to the dat on which any
such  delivery  would  otherwise  be  required  which  renders  all  such  forms
inapplicable  or  which  would  prevent  such  Bank  from  duly  completing  and
delivering  any such form with respect to it and such Bank advises the Borrowers
and the Agent that it is not capable of receiving payments without any deduction
or withholding of United States federal income tax.

     SECTION 4. Payment and Prepayment; Fees; Change in Circumstances.

     4.1 Principal Payments .

          (a) Unless  earlier  payment is  required  under this  Agreement,  the
Borrowers shall pay the entire  outstanding  principal amount of the Advances on
the Termination Date.

          (b) The Borrowers may from time to time prepay all or a portion of the
Advances without premium or penalty,  provided,  however, that (i) the Borrowers
shall have given not less than one Business  Day's prior written  notice thereof
to the Agent, (ii) other than mandatory payments,  each such prepayment,  in the
case of  prepayment of Floating  Rate Loans,  shall be in the minimum  amount of
$500,000 and in integral multiples of $100,000 and, in the case of prepayment of
Eurodollar  Loans,  shall be in the minimum amount of $1,000,000 and in integral
multiples  thereof,  (iii)  any  prepayment  of any  Eurodollar  Loan  shall  be
accompanied by any amount required pursuant to Section 4.10.

          (c) If it should be  determined by the Agent at any time and from time
to time that the principal  amount of the Advances exceed the lesser of the then
Borrowing Base or the Commitments (such condition defined herein as a "Borrowing
Base Deficiency"), the Borrowers shall within thirty (30) days of written notice
to the Borrowers of such  Borrowing  Base  Deficiency,  in addition to all other
payments of principal and interest  required to be paid on the Advances,  prepay
upon demand and without  premium or penalty the  Advances in an amount by which,
in the determination of the Agent, such aggregate  principal amount  outstanding
exceeds the lesser of the then Borrowing Base or the Commitments,  provided that
such  prepayment  shall be made  first on the Loans and if the Loans are paid in
full and such excess still exists,  the Borrowers  shall provide cash collateral
for any outstanding Letters of Credit to the extent of such remaining excess.

          (d) In addition to all other  payments  required  hereunder,  upon any
sale or other  disposition of any assets when a Default exists,  or if such sale
or other  disposition  would cause a Default,  the  Borrowers  shall  prepay the

                                      E-19
<PAGE>

Advances by an amount equal to 100% of the net proceeds  (net only of reasonable
and  customary  costs  of  such  sale or  other  disposition)  of  such  sale or
disposition, which prepayment is due upon receipt of such net proceeds.

          (e) In addition to all other  payments  required  hereunder,  upon any
sale or other disposition of any assets when a Borrowing Base Deficiency exists,
or if such sale or other  disposition  would cause a Borrowing Base  Deficiency,
the  Borrower  shall  prepay the  Advances by the amount of the  Borrowing  Base
Deficiency from the net proceeds (net only of any reasonable and customary costs
of such sale or other disposition) of such sale or disposition, which prepayment
is due upon receipt of such net proceeds.

          (f)  In  addition  to  all  other  payments  required  hereunder,  the
Borrowers  shall  prepay the Advances by an amount equal to 100% of the proceeds
of any Indebtedness (excluding Indebtedness permitted by Section 7.2(d) hereof),
provided that it is  acknowledged  that the incurrence of any such  Indebtedness
shall require the consent of the Required Banks.

          (g)  In  addition  to  all  other  payments  required  hereunder,  the
Borrowers  shall  prepay the Advances by an amount equal to 100% of the proceeds
received by the  Borrowers  from the issuance or other sale of any Capital Stock
of any Borrower,  other than net cash proceeds in an aggregate amount per fiscal
year not to exceed $2,500,000  received by CRI in connection with the exercising
of stock options.

               Unless  specified as a determination to be made by all Banks, all
determinations  made  pursuant to this Section 4.1 shall be made by the Agent or
the Required Banks, as the case may be, and shall be conclusively binding on the
parties absent manifest error.

     4.2 Interest Payment.  (a) The Borrowers shall pay interest to the Banks on
the unpaid principal  amount of each Loan for the period  commencing on the date
such Loan is made until such Loan is paid in full, on each Interest Payment Date
and at maturity (whether at stated maturity, by acceleration or otherwise),  and
thereafter on demand,  at the following rates per annum: (i) during such periods
that such Loan is a Floating Rate Loan,  the Floating Rate, and (ii) during such
periods that such Loan is a Eurodollar  Loan, the Eurodollar  Rate applicable to
such Loan for each related Eurodollar Interest Period.

          (b)  Notwithstanding the foregoing paragraph (a), the Borrowers hereby
agree,  if  requested by the  Required  Banks,  to pay interest on demand at the
Overdue  Rate on the  outstanding  principal  amount  of any Loan and any  other
amount payable by the Borrowers  hereunder (other than interest) upon and during
the continuance of any Default.

     4.3 Fees . (a) The  Borrowers  agree to pay to the Agent,  for the pro rata
account of the Banks in accordance with their Pro Rata Shares,  a commitment fee
computed at the per annum rate equal to the  Applicable  Margin on the amount by
which the Commitments exceed the aggregate  outstanding  principal amount of the
Advances,  for the period from the Effective  Date until the  Termination  Date.
Such fee shall be paid  quarterly  in arrears on the last  Business  Day of each
March, June, September and December and on the Termination Date.

          (b) The  Borrowers  agree (i) to pay to the Agent,  for the benefit of
the  Banks,  a fee  computed  at the  Applicable  Margin on the  maximum  amount
available  to be drawn under each Letter of Credit at the time such fee is to be
paid for the period  from and  including  the date of issuance of such Letter of
Credit to and  including  the stated  expiry date of such Letter of Credit,  and
(ii) to pay an additional  fee to the Agent for its own account  computed at the
rate of 0.25% per annum on such maximum amount for such period.  Such fees shall
be payable  each month in  advance,  payable on the date of the  issuance of any
Letter of Credit and each month thereafter.  Such fees are nonrefundable and the
Borrowers  shall not be entitled  to any rebate of any  portion  thereof if such
Letter of Credit  does not remain  outstanding  through  the date for which such

                                      E-20
<PAGE>

fees have been paid. The Borrowers further agree to pay to the Agent, on demand,
such other customary  administrative  fees, charges and expenses of the Agent in
respect  of the  issuance,  negotiation,  acceptance,  amendment,  transfer  and
payment  of  each  Letter  of  Credit  or  otherwise  payable  pursuant  to  the
application  and  related  documentation  under  which such  Letter of Credit is
issued.

          (c) The Borrowers  agree to pay to the Agent agency and servicing fees
for its  services  under this  Agreement  in such amounts as it may from time to
time be agreed upon  between  the  Borrowers  and the Agent,  which fee shall be
retained solely by the Agent.

     4.4 Payment  Method . All  payments to be made by the  Borrowers  hereunder
will be made in Dollars and in immediately  available  funds to the Agent at its
address set forth in Section 10.2 not later than 11:00 a.m.  Chicago time on the
date on which such payment shall become due.  Payments received after 11:00 a.m.
Chicago  time shall be deemed to be  payments  made prior to 11:00 a.m.  Chicago
time on the next  succeeding  Business  Day.  At the time of  making  each  such
payment,  the  Borrowers  shall  specify  to the Agent  that  obligation  of the
Borrowers  hereunder  to which such  payment is to be applied,  or, in the event
that the  Borrowers  fail to so  specify  or if an Event of  Default  shall have
occurred  and be  continuing,  the  Agent  may  apply  such  payments  as it may
determine in its sole  discretion.  On the day such payments are  received,  the
Agent  shall  remit  to the  Banks  their  respective  Pro Rata  Shares  of such
payments, in immediately available funds.

     4.5 No Setoff or  Deduction.  All  payments of principal of and interest on
the Advances and other amounts payable by the Borrowers  hereunder shall be made
by the  Borrowers  without  setoff or  counterclaim,  and free and clear of, and
without  deduction or  withholding  for, or on account of, any present or future
taxes, levies, imposts, duties, fees, assessments,  or other charges of whatever
nature, imposed by any governmental authority,  or by any department,  agency or
other political subdivision or taxing authority.

     4.6 Payment on Non-Business Day; Payment Computations . Except as otherwise
provided  in  this  Agreement  to the  contrary,  whenever  any  installment  of
principal  of, or interest on, any Advances  outstanding  hereunder or any other
amount due  hereunder,  becomes due and payable on a day which is not a Business
Day, the maturity thereof shall be extended to the next succeeding  Business Day
and, in the case of any  installment  of  principal,  interest  shall be payable
thereon  at the rate per annum  determined  in  accordance  with this  Agreement
during such extension. Computations of interest and other amounts due under this
Agreement shall be made on the basis of a year of 360 days for the actual number
of days  elapsed,  including  the  first day but  excluding  the last day of the
relevant period.

     4.7. Yield Protection. If any law or any governmental or quasi-governmental
rule,  regulation,  policy,  guideline or  directive  (whether or not having the
force of law),  or any  interpretation  thereof,  or the  compliance of any Bank
therewith,

                    (i) subjects any Bank or any applicable Lending Installation
to any  tax,  duty,  charge  or  withholding  on or from  payments  due from the
Borrowers  (excluding  federal taxation of the overall net income of any Bank or
applicable Lending  Installation),  or changes the basis of taxation of payments
to any Bank in respect of its Loans or other amounts due it hereunder, or

               (ii)  imposes  or  increases  or deems  applicable  any  reserve,
assessment,  insurance charge,  special deposit or similar  requirement  against
assets of,  deposits with or for the account of, or credit extended by, any Bank
or any  applicable  Lending  Installation  (other than reserves and  assessments
taken into account in  determining  the interest  rate  applicable to Eurodollar
Loans), or

               (iii)  imposes  any  other  condition  the  result of which is to
increase the cost to any Bank or any applicable Lending  Installation of making,
funding or maintaining loans or reduces any amount receivable by any Bank or any
applicable  Lending  Installation in connection with loans, or requires any Bank
or any  applicable  Lending  Installation  to make  any  payment  calculated  by
reference  to the amount of loans held or interest  received by it, by an amount

                                      E-21
<PAGE>

deemed material by such Bank,  then,  within 30 days of demand by such Bank, the
Borrowers shall pay such Bank that portion of such increased expense incurred or
reduction in an amount  received which such Bank  determines is  attributable to
making, funding and maintaining its Loans and its Commitment.

     4.8.  Changes in Capital  Adequacy  Regulations.  If a Bank  determines the
amount of capital  required  or  expected  to be  maintained  by such Bank,  any
Lending  Installation of such Bank or any corporation  controlling  such Bank is
increased as a result of a Change,  then, within 15 days of demand by such Bank,
the Borrowers  shall pay such Bank the amount  necessary to  compensate  for any
shortfall in the rate of return on the portion of such  increased  capital which
such Bank  determine  is  attributable  to this  Agreement,  its Advances or its
Commitment  (after  taking  into  account  such  Bank's  policies  as to capital
adequacy). "Change" means (i) any change after the date of this Agreement in the
Risk-Based  Capital  Guidelines  or (ii) any  adoption of or change in any other
law, governmental or quasi-governmental  rule,  regulation,  policy,  guideline,
interpretation,  or directive (whether or not having the force of law) after the
date of this Agreement which affects the amount of capital  required or expected
to be  maintained  by any Bank or any Lending  Installation  or any  corporation
controlling any Bank.  "Risk-Based  Capital Guidelines" means (i) the risk-based
capital guidelines in effect in the United States on the date of this Agreement,
including  transition  rules,  and (ii) the  corresponding  capital  regulations
promulgated by regulatory authorities outside the United States implementing the
July 1988 report of the Basle  Committee on Banking  Regulation and  Supervisory
Practices  Entitled  "International  Convergence  of  Capital  Measurements  and
Capital  Standards,"  including  transition  rules,  and any  amendments to such
regulations adopted prior to the date of this Agreement.

     4.9.  Availability  of  Types of  Advances.  If any  Bank  determines  that
maintenance of its Eurodollar  Loans at a suitable  Lending  Installation  would
violate any  applicable  law,  rule,  regulation,  or directive,  whether or not
having the force of law, or if the Required Banks determine that (i) deposits of
a type and maturity appropriate to match fund Eurodollar Loans are not available
or (ii) the interest rate  applicable  to a Type of Advance does not  accurately
reflect  the cost o making or  maintaining  such  Advance,  then the Agent shall
suspend  the  availability  of the  affected  Type of Advance  and  require  any
Eurodollar Loans of the affected Type to be repaid.

     4.10. Funding  Indemnification.  If any payment of a Eurodollar Loan occurs
on a date which is not the last day of the applicable  Interest Period,  whether
because of  acceleration,  prepayment or otherwise,  or a Eurodollar Loan is not
made on the date specified by the Borrowers for any reason other than default by
the Banks,  the Borrowers will indemnify each Bank for any loss or cost incurred
by it resulting therefrom,  including,  without limitation,  any loss or cost in
liquidating  or employing  deposits  acquired to fund or maintain the Eurodollar
Loan.

     4.11.  Bank  Statements;  Survival of Indemnity.  To the extent  reasonably
possible,  each Bank shall  designate an  alternate  Lending  Installation  with
respect to its Eurodollar Loans to reduce any liability of the Borrowers to such
Bank  under  Sections  4.7 and 4.8 or to avoid the  unavailability  of a Type of
Advance under Section 4.9, so long as such designation is not disadvantageous to
such  Bank.  Each Bank  shall  deliver a written  statement  of such Bank to the
Borrowers  (with  a copy to the  Agent)  as to the  amount  due,  if any,  under
Sections 4.7, 4.8 or 4.10. Such written  statement shall set forth in reasonable
detail the calculations upon which such Bank determined such amount and shall be
final, conclusive and binding on the Borrowers in the absence of manifest error.
Determination  of amounts  payable  under such  Sections  in  connection  with a
Eurodollar  Loan shall be calculated  as though each Bank funded its  Eurodollar
Loan through the purchase of a deposit of the type and maturity corresponding to
the deposit used as a reference in determining the Eurodollar Rate applicable to
such Loan,  whether in fact that is the case or not. Unless  otherwise  provided
herein,  the amount  specified  in the  written  statement  of any Bank shall be
payable on demand after receipt by the Borrowers of such written statement.  The
obligations  of the  Borrowers  under  Sections  4.7, 4.8 and 4.10 shall survive
payment of the Bank Obligations and termination of this Agreement.

will be validly issued and are and will be fully paid and  nonassessable and are
and will be owned,  beneficially  and of record,  by CRI,  free and clear of any
Liens.  Schedule 6.4 is a complete list of all  Subsidiaries  of CRI. COG is and
will  remain  a wholly  owned  subsidiary  of CRI and COGL is and will  remain a
wholly owned  subsidiary  of COG, and Offshore is and will remain a wholly owned
subsidiary of COGL. Comstock Management Corporation, a Nevada corporation,  does
not have  material  assets  and the  Borrowers  agree  that it will not have any
material assets at any time.

     6.5 Liens.  The  properties  of each  Borrower and each  Subsidiary  of any
Borrower  (including  without  limitation the Collateral) are not subject to any
Lien except Permitted Liens.

     6.6 Litigation.  There is no action,  suit or proceeding pending or, to the
best of its  knowledge,  threatened  against  or  affecting  it before or by any
court, governmental authority, or arbitrator which would be reasonably likely to
result in, either  individually or collectively,  a Material Adverse Effect and,
to the best of the Borrowers' knowledge,  there is no basis for any such action,
suit or proceeding.

     6.7  Financial  Condition.  The  consolidated  balance sheet of CRI and its
Subsidiaries and the consolidated  statements of income and cash flow of CRI and
its  Subsidiaries for the fiscal year ended December 31, 1997 and reported on by
Arthur Andersen,  LLP, and the interim consolidated balance sheet of CRI and its
Subsidiaries and the interim consolidated  statements of income and cash flow of
CRI and its  Subsidiaries  for the fiscal  quarter  of CRI ended June 30,  1998,
copies of which  have been  furnished  to the  Banks,  fairly  present,  and the
financial  statements of CRI and its  Subsidiaries  to be delivered  pursuant to
Section 7.1(d) will fairly present,  the consolidated  financial position of CRI
and its  Subsidiaries as of the respective  dates thereof,  and the consolidated
results of operations of CRI and its Subsidiaries  for their respective  periods
indicated,  all in accordance  with  generally  accepted  accounting  principles
consistently  applied.  There has been no event or development  which has had or
would be reasonably  likely to have a Material Adverse Effect since December 31,
1997.  There  is  no  material  Contingent  Liability  of  CRI  or  any  of  its
Subsidiaries that is not reflected in such financial  statements or in the notes
thereto.

     6.8 Use of  Advances.  The  Advances  will be used for working  capital and
general corporate  purposes.  No Borrower extends or maintains,  in the ordinary
course of business,  credit for the purpose, whether immediate,  incidental,  or
ultimate, of buying or carrying margin stock (within the meaning of Regulation U
of the Board of Governors  of the Federal  Reserve  System),  and no part of the
proceeds  of each  Advance  will be used  for the  purpose,  whether  immediate,
incidental,  or  ultimate,  of  buying  or  carrying  any such  margin  stock or
maintaining or extending  credit to others for such purpose.  After applying the
proceeds of the Advances, such margin stock will not constitute more than 25% of
the value of the assets that are subject to any  provisions of this Agreement or
any Security  Document  that may cause the  Advances to be secured,  directly or
indirectly by margin stock.

     6.9  Security  Documents.   The  Security  Documents  create  a  valid  and
enforceable first-priority lien on and perfected security interest in all right,
title and interest of each Borrower in and to the Collateral  described therein,
securing  all  amounts  intended  to  be  secured  thereby   (including  without
limitation  all  principal  of and  interest on the Notes)  subject  only to the
Permitted Liens. The respective net revenue interests of each Borrower in and to
the Oil and Gas  Interests as set forth in the Security  Documents  are true and
correct and  accurately  reflect the interests to which each Borrower is legally
entitled, subject only to the Permitted Liens.

     6.10  Consents,   Etc.  No  consent,   approval  or   authorization  of  or
declaration,  registration  or filing  with any  governmental  authority  or any
nongovernmental  Person or entity,  including without limitation any creditor or
stockholder  of it,  is  required  on the  part  of it in  connection  with  the
execution,  delivery and performance of this Agreement,  the Notes, the Security

Security Documents.

required to be filed and has paid all taxes shown  thereon to be due,  including
interest and penalties,  or has established  adequate  financial reserves on its
books and records for payment  thereof,  except where the failure to do so would
not have a Material Adverse Effect.

     6.12 Title to Properties . It has good and defensible title to, and a valid
indefeasible ownership interest in, all of its properties and assets (including,
without  limitation,  the Collateral subject to the Security Documents) free and
clear of any Lien  except the  Permitted  Liens,  and it is the owner of all the
Collateral described in the Security Documents to which it is a party. All wells
on any of the mortgaged premises have been drilled, operated, shut-in, abandoned
or  suspended  in  accordance  with  good  oil and gas  field  practices  and in
compliance with all applicable laws, permits,  statutes, orders, licenses, rules
and  regulations.  All leases with respect to any Oil and Gas Interests owned by
any  Borrower  are in good  standing  and  are in full  force  and  effect,  all
royalties,  rents,  taxes,  assessments  and other  payments  thereunder or with
respect thereto have been properly and timely paid and all conditions  necessary
to keep such leases in full force have been fully performed,  including  without
limitation  any condition to maintain  continuous  production or other  activity
with respect  thereto.  The Borrowers have delivered to the Agent title opinions
with  respect  to at  least  80% of the  value  of the  assets  included  in the
Borrowing Base.

     6.13 ERISA.  CRI and its  Subsidiaries and their Plans are in compliance in
all material  respects with those  provisions of ERISA and of the Code which are
applicable  with respect to any Plan. No prohibited  transaction  (as defined in
Section 406 of ERISA and Section 9975 of the Code) and no  reportable  event (as
defined in ERISA) has occurred with respect to any Plan. Neither CRI, any of its
Subsidiaries  nor any of its ERISA Affiliates is an employer with respect to any
multiemployer  plan (as  defined  in Section  4001(a)(3)  of  ERISA).  CRI,  its
Subsidiaries and the ERISA Affiliates have met the minimum funding  requirements
under ERISA and the Code with respect to each of the respective  Plans,  if any,
and  have not  incurred  any  liability  to the  PBGC or any  Plan.  There is no
unfunded benefit liability with respect to any Plan.

     6.14 Environmental and Safety Matters.  It is in compliance in all material
respects  with all federal,  state and local laws,  ordinances  and  regulations
relating to safety and  industrial  hygiene or to the  environmental  condition,
including without limitation all Environmental Laws in jurisdictions in which it
owns any  interest in or operates,  a well, a facility or site,  or arranges for
disposal or treatment of hazardous  substances,  solid waste,  or other  wastes,
accepts for transporting any hazardous substances, solid waste, or other wastes,
or holds any  interest in real  property  or  otherwise,  except  where any such
noncompliance  would not have a  Material  Adverse  Effect.  No  demand,  claim,
notice, suit, suit in equity, action,  administrative  action,  investigation or

                                      E-25
<PAGE>

inquiry whether brought by any governmental authority,  private Person or entity
or otherwise, arising under, relating to or in connection with any Environmental
Laws is pending or, to the best of any Borrower's knowledge,  threatened against
it, any real  property  in which it holds or has held an interest or any past or
present  operation  of  it.  It (a)  does  not  know  of any  federal  or  state
investigation  evaluating  whether any remedial action is needed to respond to a
release of any toxic  substances,  radioactive  materials,  hazardous  wastes or
related  materials into the environment,  (b) has not received any notice of any
toxic substances,  radioactive  materials,  hazardous waste or related materials
in, or upon any of its  properties in violation of any  Environmental  Laws, and
(c) does not know of any basis for any such investigation,  notice or violation.
No material release,  threatened  release or disposal of hazardous waste,  solid
waste or other  wastes is  occurring  or has  occurred  on, under or to any real
property in which it holds any  interest or performs any of its  operations,  in
violation of any Environmental Law which would have a Material Adverse Effect.

     6.15 Direct  Benefit.  The initial  Advances  hereunder and all  additional
Advances are for the direct  benefit of each of the  Borrowers,  and the initial
Advances  hereunder  are  used to  refinance  and  replace  indebtedness  owing,
directly or indirectly,  by the Borrowers to the Banks under the Existing Credit
Agreement.  The Borrowers are engaged as an integrated  group in the business of
oil and gas exploration and related fields,  and any benefits to any Borrower is
a  benefit  to all  of  them,  both  directly  or  indirectly,  inasmuch  as the
successful  operation  and  condition of the  Borrowers  is  dependent  upon the
continued  successful  performance of the functions of the integrated group as a
whole.

     6.16  Solvency.  Each of the  following  is true for each  Borrower and the
Borrowers on a consolidated  basis:  (a) the fair saleable value of its property
is (i) greater than the total amount of its  liabilities  (including  contingent
liabilities), and (ii) greater than the amount that would be required to pay its
probable aggregate  liability on its then existing debts as they become absolute
and matured; (b) its property is not unreasonable in relation to its business or
any contemplated or undertaken transaction; and (c) it does not intend to incur,
or believe  that it will  incur,  debts  beyond its ability to pay such debts as
they become due.

reports or statements or other information furnished to any Bank or the Agent in
writing by or on behalf of any Borrower in connection  with the  negotiation  or
administration  of this Agreement or any transactions  contemplated  hereby when
read together do not contain any untrue  statement of a material fact or omit to
state a material fact necessary in order to make the statements contained herein
an therein  not  misleading.  There is no fact known to any  Borrower  which has
caused,  or which likely would in the future in the  reasonable  judgment of the
Borrowers cause, a Material  Adverse Effect (except for any economic  conditions
which  affect   generally   the  industry  in  which  the  Borrowers  and  their
Subsidiaries  conduct business),  which has not been set forth in this Agreement
or  in  the  other  documents,  certificates,   statements,  reports  and  other
information furnished in writing to the Banks by or on behalf of any Borrower in
connection with the transactions contemplated hereby.

<PAGE>

equal to the maximum  amount that may be available to be drawn at any time prior
to the stated expiry of all outstanding  Letters of Credit, or all of the above,
whereupon the Commitments  shall terminate  forthwith and all such amounts shall
become  immediately due and payable,  or both, as the case may be, provided that
in the  case  of any  event  or  condition  described  in  Section  8.1(g),  the

outstanding Note or any Security Document or in aid of the exercise of any power
granted in this Agreement,  any then outstanding Notes or any Security Document,
and may enforce the payment of any then  outstanding  Notes and any of the other
rights of the Agent and the Banks in any other  agreement or available at law or
in equity.

          (c) Upon the  occurrence  and during the  continuance  of any Event of
Default  hereunder,  each  Bank may at any time and from  time to time,  without
notice to the Borrowers (any  requirement for such notice being expressly waived
by the  Borrowers)  set off and apply against any and all of the  obligations of
any Borrower now or hereafter existing under this Agreement, any of the Notes or
the  Security  Documents,  any and all  deposits  (general or  special,  time or
demand,  provisional  or final) at any time held and other  indebtedness  at any
time owing by such Bank to or for the credit or the account of any  Borrower and
any  property  of any  Borrower  from time to time in  possession  of such Bank,
irrespective of whether or not any Bank shall have made any demand hereunder and
although such  obligations  may be contingent and  unmatured.  The rights of the
Banks under this  Section  8.2(c) are in addition to other  rights and  remedies
(including,  without  limitation,  other  rights of setoff)  which the Banks may
have.

     8.3  Distribution  of  Proceeds . All  proceeds of any  realization  on the

Swap Agreement to which it is a party (whether pursuant to a termination thereof
or otherwise) and with any reimbursement  obligations or other liabilities owing
to any Bank pursuant to any Letter of Credit, for application to payment of such
liabilities;

          (c) Fourth,  to the payment of any and all other  amounts owing to the
Banks  on a pro  rata  basis  in  accordance  with  the  total  amount  of  such
Indebtedness  owing to each of the  Banks,  for  application  to payment of such
liabilities; and

     8.4  Letter  of  Credit  Liabilities.  For the  purposes  of  payments  and
distributions  under Section 8.3, the full amount of Bank Obligations on account
of any Letter of Credit then  outstanding  but not drawn upon shall be deemed to
be then due and owing.  Amounts  distributable to any of the Banks on account of
such Bank  Obligations  under  such  Letter of Credit  shall be  deposited  in a
separate  interest  bearing  collateral  account  in the name of and  under  the
control of the Agent and held by the Agent first as security  for such Letter of
Credit Bank  Obligations and then as security for all other Bank Obligations and
the  amount  so  deposited  shall  be  applied  to the  Letter  of  Credit  Bank
Obligations  at such times and to the  extent  that such  Letter of Credit  Bank
Obligations become absolute liabilities. If and to the extent that the Letter of
Credit Bank Obligations fail to become absolute Bank Obligations  because of the
expiration or  termination  of the  underlying  Letters of Credit  without being
drawn upon, then such amounts shall be applied to the remaining Bank Obligations
in the order provided in Section 8.3. Each Borrower  hereby grants to the Agent,
for the  benefit of the Banks,  a lien and  security  interest in all such funds
deposited in such separate interest bearing collateral  account, as security for
all the Bank Obligations as set forth above. The Borrowers acknowledge and agree
that all  reimbursement  and other  obligations and liabilities  pursuant to any
Letters  of  Credit  issued by the Agent for the  account  of any  Borrower  are
secured by all Collateral and the Security Documents.

     9.1 Appointment; Nature of Relationship. The First National Bank of Chicago
is hereby  appointed  by the Banks as the Agent  hereunder  and under each other
Loan Document,  and each of the Banks irrevocably authorizes the Agent to act as
the contractual representative of such Bank with the rights and duties expressly
set forth  herein and in the other Loan  Documents.  The Agent  agrees to act as
such contractual  representative  upon the express conditions  contained in this
Section 9.  Notwithstanding the use of the defined term "Agent," it is expressly
understood   and   agreed   that  the  Agent   shall  not  have  any   fiduciary
responsibilities  to any Bank by reason  of this  Agreement  or any  other  Loan
Document and that the Agent is merely acting as the  representative of the Banks
with only those  duties as are  expressly  set forth in this  Agreement  and the
other Loan Documents. In its capacity as the Banks' contractual  representative,
the Agent (i) does not hereby assume any  fiduciary  duties to any of the Banks,
(ii) is a  "representative"  of the Banks within the meaning of Section 9-105 of
the Uniform  Commercial  Code and (iii) is acting as an independent  contractor,
the rights and duties of which are limited to those  expressly set forth in this
Agreement  and the other  Loan  Documents.  Each of the Banks  hereby  agrees to
assert no claim  against the Agent on any agency  theory or any other  theory of
liability  for breach of  fiduciary  duty,  all of which claims each Bank hereby
waives.

     9.2 Powers . The Agent shall have and may  exercise  such powers  under the
Loan Documents as are  specifically  delegated to the Agent by the terms of each
thereof,  together with such powers as are reasonably  incidental  thereto.  The
Agent shall have no implied duties to the Banks,  or any obligation to the Banks
to take any action  thereunder  except any action  specifically  provided by the
Loan Documents to be taken by the Agent.

     9.3 General Immunity. Neither the Agent nor any of its directors, officers,
agents or employees shall be liable to the Borrowers, any Borrower, the Banks or
any Bank for any action taken or omitted to be taken by it or them  hereunder or
under any other Loan Document or in connection  herewith or therewith except for
its or their own gross negligence or willful misconduct.

     9.4 No Responsibility for Loans,  Recitals,  etc. Neither the Agent nor any
of its directors, officers, agents or employees shall be responsible for or have
any duty to ascertain,  inquire into, or verify (i) any  statement,  warranty or
representation  made in  connection  with any  Loan  Document  or any  borrowing
hereunder;  (ii)  the  performance  or  observance  of any of the  covenants  or
agreements  of  any  obligor  under  any  Loan  Document,   including,   without
limitation,  any agreement by an obligor to furnish information directly to each
Bank;  (iii) the  satisfaction  of any  condition  specified  in Section  3.2 or
otherwise   hereunder;   (iv)  the  validity,   enforceability,   effectiveness,
sufficiency  or  genuineness  of any Loan  Document or any other  instrument  or

                                      E-35

<PAGE>

writing  furnished  in  connection  therewith;  or (v) the  value,  sufficiency,
creation, perfection or priority of any interest in any collateral security. The
Agent  shall  have no duty to  disclose  to the  Banks  information  that is not
required to be  furnished  by the  Borrowers  to the Agent at such time,  but is
voluntarily  furnished by the  Borrowers to the Agent (either in its capacity as
Agent or in its individual capacity).

     9.5 Action on Instructions of Banks.  The Agent shall in all cases be fully
protected in acting, or in refraining from acting, hereunder and under any other
Loan Document in  accordance  with written  instructions  signed by the Required
Banks,  and such  instructions  and any action  taken or failure to act pursuant
thereto  shall be binding on all of the Banks and on all  holders of Notes.  The
Banks  hereby  acknowledge  that  the  Agent  shall be under no duty to take any
discretionary  action  permitted to be taken by it pursuant to the provisions of
this  Agreement  or any other  Loan  Document  unless it shall be  requested  in
writing to do so by the Required  Banks.  The Agent shall be fully  justified in

failing  or  refusing  to take any  action  hereunder  and under any other  Loan
Document  unless it shall first be indemnified to its  satisfaction by the Banks
pro rata  against any and all  liability,  cost and expense that it may incur by
reason of taking or continuin to take any such action.

     9.6  Employment  of Agents and  Counsel . The Agent may  execute any of its
duties  as Agent  hereunder  and under any other  Loan  Document  by or  through
employees,  agents,  and  attorneys-in-fact  and shall not be  answerable to the
Banks, except as to money or securities received by it or its authorized agents,
for the default or misconduct of any such agents or  attorneys-in-fact  selected
by it with  reasonable  care.  The Agent  shall be entitled to advice of counsel
concerning  all matters  pertaining to the agency hereby  created and its duties
hereunder and under any other Loan Document.

     9.7  Reliance on  Documents;  Counsel . The Agent shall be entitled to rely
upon any  Note,  notice,  consent,  certificate,  affidavit,  letter,  telegram,
statement,  paper or  document  believed  by it to be genuine and correct and to

legal matters,  upon the opinion of counsel selected by the Agent, which counsel
may be employees of the Agent.

     9.8  Agent's  Reimbursement  and  Indemnification  .  The  Banks  agree  to
reimburse and  indemnify  the Agent  ratably in  proportion to their  respective
Commitments (or, if the Commitments have been terminated, in proportion to their
Commitments  immediately  prior to such  termination)  (i) for any  amounts  not
reimbursed by the Borrowers for which the Agent is entitled to  reimbursement by
the Borrowers under the Loan Documents,  (ii) for any other expenses incurred by
the Agen on behalf of the Banks, in connection with the preparation,  execution,
delivery, administration and enforcement of the Loan Documents and (iii) for any
liabilities, obligations, losses, damages, penalties, actions, judgments, suits,
costs,  expenses or disbursements of any kind and nature whatsoever which may be
imposed on, incurred by or asserted  against the Agent in any way relating to or
arising out of the Loan Documents or any other document  delivered in connection
therewith or the transactions contemplated thereby, or the enforcement of any of
the terms thereof or of any such other documents, provided that no Bank shall be
liable  for any of the  foregoing  to the  extent  they  arise  from  the  gross
negligence or willful  misconduct  of the Agent.  The  obligations  of the Banks
under  this  Section  9.8 shall  survive  payment  of the Bank  Obligations  and
termination of this Agreement.

     9.9 Notice of Default.  The Agent shall not be deemed to have  knowledge or
notice of the occurrence of any Default or Event of Default hereunder unless the
Agent has received  written  notice from a Bank or a Borrower  referring to this
Agreement  describing  such  Default or Event of Default and  stating  that such
notice is a "notice of  default".  In the event that the Agent  receives  such a
notice, the Agent shall give prompt notice thereof to the Banks.

     9.10  Rights as a Bank.  In the event the Agent is a Bank,  the Agent shall
have the same rights and powers  hereunder  and under any other Loan Document as
any Bank and may exercise the same as though it were not the Agent, and the term
"Bank"  or  "Banks"  shall,  at any time when the  Agent is a Bank,  unless  the
context otherwise indicates,  include the Agent in its individual capacity.  The
Agent may accept deposits from, lend money to, and generally  engage in any kind
of trust, debt, equity or other  transaction,  in addition to those contemplated

                                      E-36

by this Agreement or any other Loan Document,  with any Borrower or any of their
respective  Subsidiaries  in  which  any  Borrower  or  such  Subsidiary  is not
restricted  hereby  from  engaging  with any other  Person.  The  Agent,  in its
individual capacity, is not obligated to remain a Bank.

     9.11  Bank  Credit   Decision.   Each  Bank   acknowledges   that  it  has,
independently and without reliance upon the Agent or any other Bank and based on
the financial  statements prepared by the Borrowers and such other documents and
information  as it has  deemed  appropriate,  made its own credit  analysis  and
decision to enter into this  Agreement and the other Loan  Documents.  Each Bank
also  acknowledges  that it will,  independently  and without  reliance upon the
Agent or any other Bank and based on such documents and  information as it shall
deem  appropriate  at the time,  continue  to make its own credit  decisions  in
taking or not taking action under this Agreement and the other Loan Documents.

     9.12  Successor  Agent . The Agent may resign at any time by giving written
notice thereof to the Banks and the Borrowers,  such resignation to be effective
upon the  appointment  of a successor  Agent or, if no successor  Agent has been
appointed,  forty-five  days  after  the  retiring  Agent  gives  notice  of its
intention to resign.  Upon any such  resignation,  the Required Banks shall have
the right to  appoint,  on behalf of the  Borrowers  and the Banks,  a successor
Agent.  If no successor Agent shall have been so appointed by the Required Banks
within thirty days after the resigning Agent's giving notice of its intention to
resign,  then the resigning Agent may appoint,  on behalf of the Borrowers,  and
the Banks, a successor  Agent.  If the Agent has resigned and no successor Agent
has been appointed,  the Banks may perform all the duties of the Agent hereunder
and the Borrowers shall make all payments in respect of the Bank  Obligations to
the  applicable  Bank and fo all other  purposes  shall deal  directly  with the
Banks. No successor  Agent shall be deemed to be appointed  hereunder until such
successor Agent has accepted the appointment.  Any such successor Agent shall be
a commercial bank having capital and retained earnings of at least  $50,000,000.
Upon the acceptance of any appointment as Agent hereunder by a successor  Agent,
such successor Agent shall  thereupon  succeed to and become vested with all the
rights,  powers,   privileges  and  duties  of  th  resigning  Agent.  Upon  the
effectiveness  of the  resignation  of the Agent,  the resigning  Agent shall be
discharged  from  its  duties  and  obligations  hereunder  and  under  the Loan
Documents.  After  the  effectiveness  of  the  resignation  of  an  Agent,  the
provisions  of this  Section 9 shall  continue in effect for the benefit of such
Agent in respect of any actions  taken or omitted to be taken by it while it was
acting as the Agent hereunder and under the other Loan Documents.

     9.13 Pro Rata  Sharing by Banks . Each Bank  agrees  with every  other Bank
that,  in the event that it shall  receive  and retain any payment on account of
the  Borrower's  obligations  under this  Agreement,  the Notes or the  Security
Documents in a greater  proportion than that received by any other Bank, whether
such payment be voluntary, involuntary or by operation of law, by application of
set-off of any indebtedness or otherwise, then such Bank shall promptly purchase
a participation interest from the other Banks, without recourse, for cash and at
face value,  ratably in  accordance  with its Pro Rata Share,  in such an amount
that each Bank shall have  received  payment in respect of such  obligations  in
accordance with its Pro Rata Share; provided,  that if any such purchase be made
by any Bank and if any such excess payment  relating thereto or any part thereof
is thereafter  recovered from such Bank,  appropriate  adjustment in the related
purchase from the other Banks shall be made by rescission and restoration of the
purchase  price as to the portion of such  excess  payment so  recovered.  It is
further  agreed that,  to the extent there is then owing by the Borrowers to any
Bank indebtedness other than that evidenced by this Agreement, the Notes and the
Security  Documents  to which such Bank may apply any  involuntary  payments  of
indebtedness by the Borrowers, including those resulting from exercise of rights
of  set-off  or  similar  rights,  such Bank  shall  apply all such  involuntary
payments first to obligations of the Borrowers to the Banks  hereunder and under
the Notes and the Security Documents and then to such other indebtedness owed to
it by the Borrowers. In addition, it is further agreed that any and all proceeds
resulting  from a sale or  other  disposition  of any  collateral  which  may be
hereafter  granted for the benefit of the Banks to secure the obligations of the
Borrowers  hereunder,  shall be applied  first to obligation of the Borrowers to
the Banks  hereunder  and under the Notes and the Security  Documents,  and then
ratably to any other  indebtedness  owed by the  Borrowers to the Banks which is
secured by such collateral.

the Borrowing Base shall be equal to $280,000,000, the Threshold Amount shall be
equal to $220,000,000  and the Borrowing Base shall reduce monthly in accordance
with the following table (such monthly reductions in the Borrowing Base, and any

Monthly Borrowing              Effective on the last 
Base Reduction                 day of the following month
- --------------                 --------------------------

$1,000,000                     February, 1999
$2,000,000                     March, 1999
$3,000,000                     April, 1999
$3,000,000                     May, 1999
$4,000,000                     June, 1999
$4,000,000                     July, 1999

$5,000,000                     October, 1999 and each month thereafter
                                 until the Borrowing Base is equal to or less
                                  than the Threshold Amount

Notwithstanding  anything  herein to the  contrary  and in addition to the above
reductions to the Borrowing  Base,  the Borrowing  Base shall further  reduce as
follows: (i) effective as of the scheduled redetermination of the Borrowing Base
based upon the receipt of the reserve  report to be delivered  by the  Borrowers
within 90 days  after  July 1, 1999  pursuant  to  Section  7.1(d)(vii)(B),  the
Borrowing  Base shall not exceed the Threshold  Amount by more than  $20,000,000
and (ii) on the first  Business Day of January,  2000,  the Borrowing Base shall
not exceed the  Threshold  Amount,  and the Borrowing  Base shall  automatically
reduce on such date to the  amount of the  Threshold  Amount  and any  amount by
which the Advances  exceed such reduced  Borrowing Base shall be due and payable
on the first Business Day of January, 2000.

          (b) Any  redetermination  of the Borrowing Base, the Threshold  Amount
and the  Monthly  Borrowing  Base  Reductions  shall  be made by the  Agent  and
submitted to the Banks.  If the  Borrowing  Base is greater  than the  Threshold
Amount, such redetermined Borrowing Base, Threshold Amount and Monthly Borrowing
Base  Reductions  shall then be effective when approved by all of the Banks.  If
the  Borrowing  Base is  equal  to or  less  than  the  Threshold  Amount,  such
redetermined  Borrowing  Base,  Threshold  Amount  and  Monthly  Borrowing  Base
Reductions  shall then be effective when approved by Banks holding not less than
75% of the aggregate  principal  amount of the Advances then outstanding (or 75%
of the  Commitments  if no  Advances  are  then  outstanding).  If  any of  such
redetermined  Borrowing  Base,  Threshold  Amount  and  Monthly  Borrowing  Base
Reductions when the Borrowing Base is equal to or less than the Threshold Amount
are not approved by Banks holding not less than 75% of the  aggregate  principal
amount  of the  Advances  then  outstanding  (or  75% of the  Commitments  if no
Advances are then outstanding)  within ten (10) days after they are submitted to
the Banks, each Bank shall submit to the Agent, on or within ten (10) days after
the  Agent  notifies  the Banks  that  such  Banks  have not  approved  any such
redetermined   Borrowing  Base,  Threshold  Amount  or  Monthly  Borrowing  Base
Reductions,  its  determination  of  each  of the  foregoing  which  was  not so
approved,  and the redetermined amount of each of the foregoing which was not so
approved  will be based  on the  weighted  average  of the  redetermined  amount
thereof of each Bank which properly submits such  redetermination  to the Agent,
weighted according to each Bank's Commitment. Notwithstanding anything herein to
the contrary,  any increase in the Borrowing  Base or the Threshold  Amount from
the amount thereof most recently determined shall require the approval of all of
the Banks.

          (c) The Borrowing Base, the Threshold Amount and the Monthly Borrowing
Base  Reductions  may be  redetermined  from  time to time as  requested  by the
Required  Banks,  and will be  redetermined  upon the  request of the  Borrowers
(provided that the Borrowers cannot request a  redetermination  of the Borrowing
Base, the Threshold  Amount or the Monthly  Borrowing Base  Reductions more than
once between the mandatory  redeterminations  hereinafter provided for), and, in
addition,  at least  twice each year as  follows:  upon  receipt of the  reserve
reports referred to in Section  7.1(d)(vii)  hereof (and in connection with such
twice per year  redeterminations of the Borrowing Base, the Threshold Amount and
the Monthly  Borrowing Base  Reductions the Agent shall submit the  redetermined
Borrowing Base, the Threshold  Amount and the Monthly  Borrowing Base Reductions
as required  under this Section 9.14 on or prior to 30 days after the receipt of
each (i) reserve report  referred to in Section  7.1(d)(vii) (A) hereof and (ii)
reserve report referred to in Section  7.1(d)(vii)(B)).  Each redetermination of
the Monthly  Borrowing Base Reductions  shall determine such reductions for each
of the six months following such  determination,  provided the Monthly Borrowing
Base Reductions  described in Section 9.14(a) above may not be modified  without
the consent of all the Banks.  Except for the scheduled  redeterminations of the
Borrowing Base, the Threshold Amount and the Monthly  Borrowing Base Reductions,
each Bank  requesting a  redetermination  of the Borrowing  Base,  the Threshold
Amount and the Monthly  Borrowing Base  Reductions  agrees to give notice to the
Agent and the Borrowers of such request.

Agent hereunder, shall have no duties or liabilities.

               (b) Any such amendment,  waiver or termination shall be effective
only in the specific instance and for the specific purpose for which given.

               (c)  Notwithstanding  anything  herein to the contrary,  any Bank
that has failed to fund any  Advance or other  amount  required  to be funded by
such Bank  hereunder  shall not be  entitled  to vote  (whether to consent or to
withhold its consent) with respect to any amendment,  modification,  termination
or waiver of any provision of any Loan Document or a departure  therefrom or any
direction  from the Banks to the Agent and,  for  purposes  of  determining  the
Required Banks, the Commitments and Advances of such Bank shall be disregarded.

part of the  Agent or the  Banks,  nor any delay or  failure  on the part of the
Agent or any Bank in exercising any right,  power or privilege  hereunder  shall

and those  covenants  and  agreements of the Borrowers set forth in Section 10.5
hereof shall survive the repayment in full of the Advances and other obligations
of the Borrowers  hereunder and under Security  Documents and the termination of
the Commitments.

     10.5 Expenses;  Indemnification  . (a) The Borrowers  agree to pay and save
the Agent  harmless from  liability for the payment of the  reasonable  fees and
expenses  of any  counsel  the  Agent  shall  employ,  in  connection  with  the
preparation,  execution  and  delivery  of this  Agreement,  the  Notes  and the
Security Documents and the consummation of the transactions  contemplated hereby
and in connection with any amendments,  waivers or consents and other matters in
connection therewith, and all reasonable costs and expenses of the Agent and the
Banks (including reasonable fees and expenses of counsel) in connection with any
enforcement of this Agreement, the Notes or the Security Documents.

          (b)  Each of the  Borrowers  hereby  indemnifies  and  agrees  to hold
harmless  the Banks and the Agent,  and their  respective  officers,  directors,
employees  and agents,  from and against  any and all claims,  damages,  losses,
liabilities,  costs or expenses of any kind or nature whatsoever which the Banks
or the Agent or any such Person may incur or which may be claimed against any of
them by reason of or in  connection  with any Letter of Credit,  and neither any
Bank nor the Agent or any of their respective officers, directors,  employees or
agents shall be liable or responsible  for: (i) the use which may be made of any
Letter of Credit or for any acts or omissions of any  beneficiary  in connection
therewith; (ii) the validity,  sufficiency or genuineness of documents or of any
endorsement thereon, even if such documents should in fact prove to be in any or
all respects invalid,  insufficient,  fraudulent or forged; (iii) payment by the
Agent to the  beneficiary  under any Letter of Credit  against  presentation  of
documents which do not comply with the terms of any Letter of Credit,  including
failure of any  documents to bear any  reference  or adequate  reference to such
Letter  of  Credit;  (iv)  any  error,   omission,   interruption  or  delay  in
transmission,   dispatch  or   delivery  of  any  message  or  advice,   however
transmitted,  in connection with any Letter of Credit; or (v) any other event or
circumstance  whatsoever  arising  in  connection  with any  Letter  of  Credit;
provided,  however,  that the  Borrowers  shall not be required to indemnify the
Agent and such other Persons,  and the Agent shall be liable to the Borrowers to
the extent,  but only to the extent,  of any direct, as opposed to consequential
or  incidental,  damages  suffered by any Borrower  which were caused by (A) the
Agent's  wrongful  dishonor of any Letter of Credit after the presentation to it
by the  beneficiary  thereunder of a draft or other demand for payment and other

                                      E-40
<PAGE>

documentation strictly complying with the terms and conditions of such Letter of
Credit,  or (B) the payment by the Agent to the beneficiary  under any Letter of
Credit against  presentation  of documents which do not comply with the terms of
the Letter of Credit to the extent,  but only to the extent,  that such  payment
constitutes gross negligence or wilful misconduct of the Agent. It is understood
that in making  any  payment  under a Letter of  Credit  the Agent  will rely on
documents  presented to it under such Letter of Credit as to any and all matters
set forth therein without further  investigation and regardless of any notice or
information  to the contrary,  and such reliance and payment  against  documents
presented  under a Letter  of  Credit  substantially  complying  with the  terms
thereof shall not be deemed gross  negligence or wilful  misconduct of the Agent
in connection with such payment.  It is further  acknowledged  and agreed that a
Borrower may have rights against the  beneficiary  or others in connection  with
any Letter of Credit with respect to which the Agent is alleged to be liable and
it shall be a precondition  of the assertion of any liability of the Agent under
this  Section  that such  Borrower  shall first have taken  reasonable  steps to
enforce remedies in respect of the alleged loss against such beneficiary and any
other parties  obligated or liable in connection  with such Letter of Credit and
any related transactions.

          (c) In  consideration  of the execution and delivery of this Agreement
by  each  Bank  and the  extension  of the  Commitments,  the  Borrowers  hereby
indemnify,  exonerate and hold the Agent, each Bank and each of their respective
officers,  directors,  employees  and  agents  (collectively,  the  "Indemnified
Parties")  free and  harmless  from and against any and all  actions,  causes of
action, suits, losses, costs,  liabilities and damages, and expenses incurred in
connection  therewit  (irrespective of whether any such  Indemnified  Party is a
party to the action for which  indemnification  hereunder is sought),  including
reasonable  attorneys' fees and  disbursements  (collectively,  the "Indemnified
Liabilities"),  incurred by the  Indemnified  Parties or any of them as a result
of, or arising out of, or relating to:

               (i) any  transaction  financed  or to be  financed in whole or in
part, directly or indirectly, with the proceeds of any Advance;

               (ii) the entering into and  performance of this Agreement and any
other  agreement or  instrument  executed in  connection  herewith by any of the
Indemnified  Parties  (including  any  action  brought  by or on  behalf  of the
Borrowers as the result of any  determination  by the Required Banks not to fund
any Advance in compliance with this Agreement);

               (iii) any investigation,  litigation or proceeding related to any
acquisition   or  proposed   acquisition  by  the  Borrowers  or  any  of  their
Subsidiaries of any portion of the stock or assets of any Person, whether or not
the Agent or such Bank is party thereto;

               (iv) any  investigation,  litigation or proceeding related to any
environmental cleanup, audit, compliance or other matter relating to any release
by the Borrowers or any of their  Subsidiaries of any hazardous  material or any
violations of Environmental Laws; or

               (v) the presence on or under,  or the escape,  seepage,  leakage,
spillage, discharge,  emission,  discharging or releases from, any real property
owned or operated by the  Borrowers or any  Subsidiary  thereof of any Hazardous
Material (including any losses, liabilities,  damages, injuries, costs, expenses
or claims  asserted  or arising  under any  Environmental  Law),  regardless  of
whether  caused by, or within the control of, the Borrowers or such  Subsidiary,
except  for any  such  Indemnified  Liabilities  arising  for the  account  of a
particular  Indemnified  Party by reason of the  activities  of the  Indemnified
Party on the property of the Borrowers conducted  subsequent to a foreclosure on
such  property  by the Banks or by reason of the  relevant  Indemnified  Party's
gross negligence or wilful misconduct or breach of this Agreement, and if and to

                                      E-41

<PAGE>

the extent that the foregoing  undertaking may be unenforceable  for any reason,
the Borrowers  hereby agree to make the maximum  contribution to the payment and
satisfaction of each of the Indemnified  Liabilities  which is permissible under
applicable  law. The Borrowers  shall be obligated to indemnify the  Indemnified
Parties for all Indemnified Liabilities subject to and pursuant to the foregoing
provisions, regardless of whether the Borrowers or any of their Subsidiaries had
knowledge  of the  facts  and  circumstances  giving  rise to  such  Indemnified
Liability.

     10.6  Successors and Assigns . (a) This Agreement shall be binding upon and
inure to the benefit of the parties hereto and their  respective  successors and
assigns,  provided that the Borrowers may not,  without the prior consent of the
Banks,  assign their rights or obligations  hereunder or under the Notes and the
Banks shall not be obligated  to make any Advance  hereunder to any entity other
than the Borrowers.

          (b) Any  Bank  may  sell a  participation  interest  to any  financial
institution or institutions,  and such financial institution or institutions may
further sell, a participation  interest  (undivided or divided) in, the Advances
and such Bank's  rights and  benefits  under this  Agreement,  the Notes and the
Security Documents and to the extent of that participation,  such participant or
participants shall have the same rights and benefits against the Borrowers under
Section 6.2(c) as it or they would have had if participation of such participant
or  participants  were the Bank making the Advances to the Borrowers  hereunder,
provided,  however,  that (i) such Bank's obligations under this Agreement shall
remain  unmodified and fully effective and  enforceable  against such Bank, (ii)
such Bank shall remain solely  responsible  to the other parties  hereto for the
performance of such obligations,  (iii) such Bank shall remain the holder of its
Note for all purposes of this Agreement,  (iv) the Borrowers,  the Agent and the
other  Banks  shall  continue  to deal  solely  and  directly  with such Bank in
connection with such Bank's rights and obligations under this Agreement, and (v)
such Bank shall not grant to its  participant  any rights to consent or withhold
consent to any action taken by such Bank or the Agent under this Agreement other
than action requiring the consent of all of the Banks hereunder.  The Agent from
time to time in its sole  discretion  may  appoint  agents  for the  purpose  of
servicing and  administering  this Agreement and the  transactions  contemplated
hereby and enforcing or exercising  any rights or remedies of the Agent provided
under this Agreement,  the Notes,  or otherwise.  In furtherance of such agency,
the Agent may from  time to time  direct  that the  Borrowers  provide  notices,
reports  and other  documents  contemplated  by this  Agreement  (or  duplicates
thereof) to such agent.  The Borrowers hereby consent to the appointment of such
agent and agree to provide all such notices,  reports and other documents and to
otherwise  deal with such agent acting on behalf of the Agent in the same manner
as would be required if dealing with the Agent itself.

          (c) Each Bank may,  with the prior  consent  of the  Borrowers  (which
consent  shall not be  unreasonably  withheld and shall not be required upon the
occurrence and during the continuance of any Event of Default which is not cured
or  waived  within 30 days (or 0 days in the case of an Event of  Default  under
Section  8.1(g))  after  the  occurrence  of such  Event of  Default  or if such
assignment  by such Bank is to an Affiliate of such Bank or to another Bank) and
the Agent, assign to one or more banks or other entities all or a portion of its
rights and obligations under this Agreement (including,  without limitation, all
or a portion of its  Commitment,  the Advances owing to it and the Note or Notes
and the Security  Documents held by it); provided,  however,  that (i) each such
assignment  shall be of a uniform,  and not a varying,  percentage of all rights
and  obligations,  (ii) except in the case of an  assignment  of all of a Bank's
rights and obligations under this Agreement, (A) the amount of the Commitment of
the assigning Bank being assigned  pursuant to each such assignment  (determined
as of the date of the Assignment and Acceptance with respect to such assignment)
shall  in no  event  be less  than  $5,000,000,  and in  integral  multiples  of
$1,000,000 thereafter,  or such lesser amount as the Borrowers and the Agent may
consent to and (B) after giving  effect to each such  assignment,  the amount of
the Commitment of the assigning Bank shall in no event be less than  $5,000,000,
and (iii) the parties to each such  assignment  shall execute and deliver to the
Agent,  for its  acceptance  and  recording in the Register,  an Assignment  and
Acceptance  in the form of Exhibit D hereto (an  "Assignment  and  Acceptance"),
together with any Note or Notes subject to such  assignment and a processing and
recordation  fee of  $3,500.  Upon  such  execution,  delivery,  acceptance  and
recording,  from and after the effective  date  specified in such  Assignment an
Acceptance,  (x) the  assignee  thereunder  shall be a party  hereto and, to the
extent that rights and  obligations  hereunder have been assigned to it pursuant
to such  Assignment and  Acceptance,  have the rights and  obligations of a Bank
hereunder and (y) the Bank assignor  thereunder shall, to the extent that rights
and  obligations  hereunder have been assigned by it pursuant to such Assignment

                                      E-42

and Acceptance, relinquish its rights and be released from its obligations under
this Agreement (and, in the case of an Assignment and Acceptance covering all of
the remaining  portion of an assigning Bank's rights and obligations  under this
Agreement, such Bank shall cease to be a party hereto).

          (d) By executing and delivering an Assignment and Acceptance, the Bank
assignor  thereunder and the assignee  thereunder confirm to and agree with each
other and the other  parties  hereto as  follows:  (i) other than as provided in
such Assignment and Acceptance,  such assigning Bank makes no  representation or
warranty  and  assumes  no  responsibility   with  respect  to  any  statements,
warranties or  representations  made in or in connection  with this Agreement or
the execution, legality, validity, enforceability,  genuineness,  sufficiency or
value of this Agreement or any other instrument or document  furnished  pursuant
hereto; (ii) such assigning Bank makes no representation or warranty and assumes
no  responsibility  with respect to the financial  condition of the Borrowers or
the performance or observance by the Borrowers of any of their obligations under
this Agreement or any other  instrument or document  furnished  pursuant hereto;
(iii) such  assignee  confirms  that it has  received a copy of this  Agreement,
together with copies of the financial  statements referred to in Section 6.7 and
such other  documents and  information as it has deemed  appropriate to make its
own credit  analysis and decision to enter into such  Assignment and Acceptance;
(iv) such assignee will,  independently  and without reliance on the Agent, such
assigning Bank or any other Bank and based on such documents and  information as
it shall deem appropriate at the time,  continue t make its own credit decisions
in taking or not taking action under this Agreement;  (v) such assignee appoints
and  authorizes  the Agent to take such  action  as agent on its  behalf  and to
exercise such powers and discretion under this Agreement as are delegated to the
Agent by the terms  hereof,  together  with such  powers and  discretion  as are
reasonably  incidental  thereto;  and (vi)  such  assignee  agrees  that it will
perform in accordance with their terms all of the obligations  that by the terms
of this Agreement are required to be performed by it as a Bank.

          (e)  The  Agent  shall  maintain  at  its  address  designated  on the
signature pages hereof a copy of each Assignment and Acceptance delivered to and
accepted by it and a register for the  recordation of the names and addresses of
the Banks and the Commitment of, and principal  amount of the Advances owing to,
each Bank from time to time (the "Register").  The entries in the Register shall
be  conclusive  and binding for all purposes,  absent  manifest  error,  and the
Borrowers,  the Agent and the Banks may treat each Person whose name is recorded
in the  Register as a Bank  hereunder  for all purposes of this  Agreement.  The
Register  shall be available for  inspection by the Borrowers or any Bank at any
reasonable time and from time to time upon reasonable prior notice.

          (f) Upon its receipt of an Assignment  and  Acceptance  executed by an
assigning Bank and an assignee,  together with any Note or Notes subject to such
assignment,  the  Agent  shall,  if such  Assignment  and  Acceptance  has  been
completed,   (i)  accept  such  Assignment  and  Acceptance,   (ii)  record  the
information  contained  therein in the  Register  and (iii) give  prompt  notice
thereof to the  Borrowers.  Within five  Business Days after its receipt of such
notice,  the Borrowers,  at their own expense,  shall execute and deliver to the
Agent in exchange for the  surrendered  Note or Notes a new Note to the order of
such  assignee in an amount  equal to the  Commitment  assumed by it pursuant to
such  Assignment  and  Acceptance  and,  if the  assigning  Bank has  retained a
Commitment hereunder, a new Note to the order of the assigning Bank in an amount
equal to the Commitment  retained by it hereunder.  Such new Note or Notes shall
be in an aggregate  principal amount equal to the aggregate  principal amount of
such  surrendered  Note or  Notes,  shall be dated  the  effective  date of such
Assignment and Acceptance and shall  otherwise be in  substantially  the form of
Exhibit B hereto.

          (g) The Banks may, in connection with any assignment or  participation
or proposed assignment or participation  pursuant to this Section 10.6, disclose
to the  assignee  or  participant  or  proposed  assignee  or  participant,  any
information  relating to the Borrowers,  provided that such proposed assignee or
participant  has agreed to hold such  information  confidential  under the terms
described in Section 10.20.

          (h)  Notwithstanding any other provisions set forth in this Agreement,
any Bank may at any time create a security  interest  in, or assign,  all or any
portion of its rights under this Agreement (including,  without limitation,  the

                                      E-43

<PAGE>

Advances  owing to it and the Note or Notes held by it) in favor of any  Federal
Reserve Bank in  accordance  with  Regulation A of the Board of Governors of the
Federal  Reserve System;  provided that such creation of a security  interest or
assignment  shall  not  release  such  Bank  from  its  obligations  under  this
Agreement.

     10.7  Subsidiaries  as  Borrowers.  In the  event  that CRI,  COG,  COGL or
Offshore shall create or acquire a Subsidiary,  such Subsidiary  shall execute a
joinder agreement in form and substance satisfactory to the Agent, together with
such  Security  Documents,  other  documents  and  opinions  as  the  Agent  may
reasonably require, and shall become a Borrower hereunder.

     10.8  CHOICE OF LAW.  THE LOAN  DOCUMENTS  (OTHER THAN THOSE  CONTAINING  A
CONTRARY  EXPRESS CHOICE OF LAW PROVISION) SHALL BE CONSTRUED IN ACCORDANCE WITH
THE INTERNAL LAWS (AND NOT THE LAW OF  CONFLICTS) OF THE STATE OF ILLINOIS,  BUT
GIVING EFFECT TO FEDERAL LAWS APPLICABLE TO NATIONAL BANKS.

     10.9 Table of Contents and Headings. The table of contents and the headings
of the various subdivisions hereof are for the convenience of reference only and
shall in no way modify any of the terms or provisions hereof.

     10.10  Construction  of  Certain  Provisions  . All  computations  required
hereunder  and all  financial  terms used herein  shall be made or  construed in
accordance  with GAAP unless such principles are  inconsistent  with the express
requirements of this Agreement. If any provision of this Agreement refers to any
action  to be taken by any  Person,  or which  such  Person is  prohibited  from
taking, such provision shall be applicable whether such action is taken directly
or  indirectly  by such  Person,  whether  or not  expressly  specified  in such
provision.

     10.11  Integration  and  Severability.  This Agreement  embodies the entire
agreement and understanding  between the Borrowers and the Banks, and supersedes
all prior agreements and understandings,  relating to the subject matter hereof.
In  case  any  one or  more  of the  obligations  of the  Borrowers  under  this
Agreement,  the Notes or any  Security  Documents  shall be invalid,  illegal or
unenforceable in any jurisdiction,  the validity, legality and enforceability of
the remaining  obligations of the Borrowers  shall not in any way be affected or
impaired thereby,  and such invalidity,  illegality or  unenforceability  in one
jurisdiction  shall not affect the validity,  legality or  enforceability of the
obligations  of the Borrowers  under this  Agreement,  the Notes or any Security
Documents in any other jurisdiction.

     10.12  Interest Rate  Limitation .  Notwithstanding  any provisions of this
Agreement,  the Notes or any Security Documents, in no event shall the amount of
interest paid or agreed to be paid by the Borrowers exceed an amount computed at
the highest  rate of interest  permissible  under  applicable  law. If, from any
circumstances  whatsoever,  fulfillment of any provision of this Agreement,  the
Notes or any Security  Documents at the time performance of such provision shall
be due, shall involve exceeding the interest rate limitation  validly prescribed
by law which a court of competent jurisdiction may deem applicable hereto, then,
ipso  facto,  the  obligations  to be  fulfilled  shall be  reduced to an amount
computed at the highest rate of interest  permissible  under applicable law, and
if for any reason  whatsoever the Banks shall ever receive as interest an amount
which would be deemed  unlawful under such applicable law such interest shall be
automatically  applied to the payment of principal  of the Advances  outstanding
and other  obligations of the Borrowers  hereunder  (whether or not then due and
payable)  and not to the  payment  of  interest,  or  shall be  refunded  to the
Borrowers  if such  principal  has been  paid in full.  Anything  herein  to the
contrary notwithstanding,  the obligations of the Borrowers under this Agreement
shall be  subject to the  limitation  that  payments  of  interest  shall not be
required  to the extent that  receipt of any such  payment by the Banks would be
contrary to provisions  of law  applicable to the Banks which limits the maximum
rate of interest which may be charged or collected by the Banks.

                                      E-44

     10.13  Counterparts.  This  Agreement  may be  executed  in any  number  of
counterparts,  all of which taken  together  shall  constitute  one and the same
instrument  and any of the parties  hereto may execute this Agreement by signing
any such counterpart.

     10.14  Independence  of Covenants.  All covenants  hereunder shall be given
independent  effect so that if a particular action or condition is not permitted
by any such covenant, the fact that it would be permitted by an exception to, or
would be otherwise  within the limitations of, another  covenant shall not avoid
the  occurrence  of an Event of  Default  or any event or  condition  which with
notice or lapse of time, or both, could become such an Event of Default if such
action is taken or such condition exists.

     10.15  Consent  to  Jurisdiction.   Notwithstanding  the  place  where  any
liability  originates  or  arises,  or is to be  repaid,  any  suit,  action  or
proceeding arising out of or relating to this Agreement, any Security Documents,
or the Notes may be  instituted  in any court of competent  jurisdiction  in the
State of Illinois,  each Borrower hereby  irrevocably waives any objection which
it may have or  hereafter  has to the  laying  of such  venue of any such  suit,
action or proceeding and any claim that any such suit,  action or proceeding has
been brought in an  inconvenient  forum,  and each Borrower  hereby  irrevocably
submits  its Person and  property to the  jurisdiction  of any such court in any
such suit, action or proceedings. Nothing in this Section 10.15 shall affect the
right of the Bank to bring  proceedings  against the  Borrowers  or any of their
property in the courts of any other court of competent jurisdiction.

     10.16 JURY TRIAL  WAIVER . THE AGENT,  THE BANKS AND EACH  BORROWER,  AFTER
CONSULTING OR HAVING HAD THE  OPPORTUNITY  TO CONSULT WITH  COUNSEL,  KNOWINGLY,
VOLUNTARILY AND INTENTIONALLY WAIVE ANY RIGHT ANY OF THEM MAY HAVE TO A TRIAL BY
JURY IN ANY LITIGATION  BASED UPON OR ARISING OUT OF THIS AGREEMENT,  THE NOTES,
THE SECURITY  DOCUMENTS,  OR ANY RELATED  INSTRUMENT  OR AGREEMENT OR ANY OF THE
TRANSACTIONS CONTEMPLATED BY THIS AGREEMENT, THE NOTES OR THE SECURITY DOCUMENTS
OR ANY COURSE OF  CONDUCT,  DEALING,  STATEMENTS  (WHETHER  ORAL OR  WRITTEN) OR
ACTIONS OF ANY OF THEM. NEITHER THE AGENT, THE BANKS NOR ANY BORROWER SHALL SEEK
TO CONSOLIDATE,  BY  COUNTERCLAIM OR OTHERWISE,  ANY SUCH ACTION IN WHICH A JURY
TRIAL HAS BEEN WAIVED WITH ANY OTHER  ACTION IN WHICH A JURY TRIAL  CANNOT BE OR
HAS NOT BEEN WAIVED.  THESE PROVISIONS SHALL NOT BE DEEMED TO HAVE BEEN MODIFIED
IN ANY  RESPECT  OR  RELINQUISHED  BY  EITHER  THE  AGENT  AND THE  BANKS OR THE
BORROWERS EXCEPT BY A WRITTEN INSTRUMENT EXECUTED BY ALL OF THEM.

     10.17 Joint and Several Obligations;  Contribution Rights; Savings Clause .
(a) Notwithstanding  anything to the contrary set forth herein or in any Note or
in any other Loan Document, the obligations of the Borrowers hereunder and under
the   Notes   and  the   other   Loan   Documents   are   joint   and   several.

          (b)  If  any  Borrower   makes  a  payment  in  respect  of  the  Bank
Obligations,  it shall have the rights of  contribution  set forth below against
the other Borrowers; provided that such Borrower shall not exercise its right of
contribution until all the Bank Obligations shall have been finally paid in full
in cash. If any Borrower makes a payment in respect of the Bank Obligations that
is smaller in proportion to its Payment Share (as hereinafter defined) than such
payments  made by the other  Borrowers are in proportion to the amounts of their
respective  Payment  Shares,  the Borrower making such  proportionately  smaller
payment  shall,  when  permitted  by the  preceding  sentence,  pay to the other
Borrowers an amount such that the net  payments  made by the Borrower in respect
of the  Bank  Obligations  shall  be  shared  among  the  Borrowers  pro rata in
proportion to their  respective  Payment  Shares.  If any Borrower  receives any
payment that is greater in proportion  to the amount of its Payment  Shares than
the payments received by the other Borrowers are in proportion to the amounts of
their respective  Payment Shares,  the Borrower  receiving such  proportionately
greater payment shall, when permitted by the second preceding  sentence,  pay to

                                      E-45

<PAGE>

the other  Borrowers an amount such that the payments  received by the Borrowers
shall be shared among the Borrowers  pro rata in proportion to their  respective
Payment  Shares.  Notwithstanding  anything to the  contrary  contained  in this
paragraph or in this Agreement,  no liability or obligation of any Borrower that
shall  accrue  pursuant to this  paragraph  shall be paid nor shall it be deemed
owed  pursuant  to this  paragraph  until all of the Bank  Obligations  shall be
finally paid in full in cash.

     For purposes hereof,  the "Payment Share" of each Borrower shall be the sum
of (a) the aggregate proceeds of the Bank Obligations  received by such Borrower
plus (b) the product of (i) the aggregate Bank  Obligations  remaining unpaid on
the date such Bank Obligations become due and payable in full, whether by stated
maturity,  acceleration,  or otherwise (the "Determination Date") reduced by the
amount of such Bank Obligations  attributed to all or such Borrowers pursuant to
clause  (a  above,  times  (ii) a  fraction,  the  numerator  of  which  is such
Borrower's net worth on the effective  date of this Agreement  (determined as of
the end of the immediately  preceding fiscal reporting period of such Borrower),
and the denominator of which is the aggregate net worth of all Borrowers on such
effective date.

          (c) It is the  intent of each  Borrower,  the Agent and the Banks that
each Borrower's maximum Bank Obligations shall be in, but not in excess of:

               (i) in a case or proceeding commenced by or against such Borrower
under the  Bankruptcy  Code on or within  one year from the date on which any of
the Bank  Obligations are incurred,  the maximum amount that would not otherwise
cause the Bank  Obligations  (or any other  obligations  of such Borrower to the
Agent and the Banks) to be avoidable  or  unenforceable  against  such  Borrower
under  (A)  Section  548 of the  Bankruptcy  Code  or (B) any  state  fraudulent
transfer  or  fraudulent  conveyance  act or  statute  applied  in such  case or
proceeding by virtue of Section 544 of the Bankruptcy Code; or

               (ii)  in a  case  or  proceeding  commenced  by or  against  such
Borrower under the Bankruptcy Code subsequent to one year from the date on which
any of the Bank  Obligations  are  incurred,  the maximum  amount that would not
otherwise cause the Bank Obligations (or any other  obligations of such Borrower
to the Agent and the  Banks)  to be  avoidable  or  unenforceable  against  such
Borrower  under any state  fraudulent  transfer or fraudulent  conveyance act or
statute  applied in any such case or  proceeding by virtue of Section 544 of the
Bankruptcy Code; or

               (iii)  in a case  or  proceeding  commenced  by or  against  such
Borrower under any law,  statute or regulation  other than the  Bankruptcy  Code
(including,   without   limitation,   any  other   bankruptcy,   reorganization,
arrangement,  moratorium,  readjustment  of debt,  dissolution,  liquidation  or
similar debtor relief laws),  the maximum amount that would not otherwise  cause
the Bank Obligations (or any other obligations of such Borrower to the Agent and
the Banks) to be avoidable or  unenforceable  against such  Borrower  under such
law, statute or regulation including,  without limitation,  any state fraudulent
transfer or  fraudulent  conveyance  act or statute  applied in any such case or
proceeding.

          (d) The Borrowers  acknowledge and agree that they have requested that
the Banks make credit available to the Borrowers with each Borrower expecting to
derive  benefit,  directly  and  indirectly,  from the Advances and other credit
extended by the Banks to the Borrowers.

     10.18  Consents to Renewals,  Modifications  and Other Actions and Events .
This  Agreement  and all of the  obligations  of the Borrowers  hereunder  shall
remain in full force and  effect  without  regard to and shall not be  released,
affected or impaired by: (a) any amendment,  assignment,  transfer, modification
of or addition or supplement to the Bank Obligations,  this Agreement,  any Note
or any other Loan Document; (b) any extension,  indulgence, increase in the Bank
Obligations  or other action or inaction in respect of any of the Loan Documents
or otherwise with respect to the Bank Obligations, or any acceptance of security
for, or guaranties  of, any of the Bank  Obligations or Loan  Documents,  or any
surrender,  release, exchange,  impairment or alteration of any such security or
guaranties  including  without  limitation  the  failing  to  perfect a security
interest  in any  such  security  or  abstaining  from  taking  advantage  or of
realizing  upon  any  guaranties  or upon  any  security  interest  in any  such

                                      E-46

<PAGE>

security;  (c) any default by any Borrower  under, or any lack of due execution,
invalidity or  unenforceability  of, or any irregularity or other defect in, any
of the Loan  Documents;  (d) any waiver by the Banks or any other  Person of any
required  performance  or otherwise of any condition  precedent or waiver of any
requirement  imposed by any of the Loan  Documents,  any guaranties or otherwise
with respect to the Bank  Obligations;  (e) any exercise or  non-exercise of any
right,  remedy,  power or privilege  in respect of this  Agreement or any of the
other Loan Documents;  (f) any sale, lease, transfer or other disposition of the
assets of any Borrower or any  consolidation  or merger of any Borrower  with or
into  any  other  Person,  corporation,  or  entity,  or any  transfer  or other
disposition  by any Borrower or any other holder of any shares of capital  stock
of any  Borrower;  (g) any  bankruptcy,  insolvency,  reorganization  or similar
proceedings involving or affecting any Borrower; (h) the release or discharge of
any Borrower from the performance or observance of any agreement, covenant, term
or condition  under any of the Bank  Obligations or contained in any of the Loan
Documents  by  operation  of law;  or (i) any other  cause  whether  similar  or
dissimilar  to the  foregoing  which,  in the absence of this  provision,  would
release, affect or impair the obligations,  covenants,  agreements and duties of
any Borrower hereunder,  including without limitation any act or omission by the
Agent,  or the Bank or any other any Person  which  increases  the scope of such
Borrower's risk; and in each case described in this paragraph whether or not any
Borrower shall have notice or knowledge of any of the  foregoing,  each of which
is specifically waived by each Borrower. Each Borrower warrants to the Agent and
the Banks that it has  adequate  means to obtain  from each other  Borrower on a
continuing  basis  information  concerning  the  financial  condition  and other
matters with respect to the Borrowers and that it is not relying on the Agent or
the Banks to provide such information either now or in the future.

     10.19 Waivers,  Etc . Each Borrower  unconditionally  waives: (a) notice of
any of the matters referred to in Section 10.18 above; (b) all notices which may
be required by statute,  rule or law or  otherwise to preserve any rights of the
Agent or the Banks including,  without limitation,  presentment to and demand of
payment or performance  from the other  Borrowers and protect for non-payment or
dishonor;  (c) any right to the exercise by the Agent or the Banks of any right,
remedy, power or privilege in connection with any of the Loan Documents; (d) any
requirement  that the  Agent or the  Banks in the  event of any  default  by any
Borrower,  first make  demand  upon or seek to enforce  remedies  against,  such
Borrower or any other  Borrower  before  demanding  payment  under or seeking to
enforce this Agreement  against any other  Borrower;  (f) any right to notice of
the  disposition  of any security which the Agent or the Banks may hold from any
Borrower or otherwise and an right to object to the commercial reasonableness of
the  disposition  of any such  security;  and (g) all  errors and  omissions  in
connection  with the  Agent's  or any Bank's  administration  of any of the Bank
Obligations,  any of the Loan  Documents,  or any other act or  omission  of the
Agent or any Bank which changes the scope of the  Borrower's  risk,  except as a
result of the gross  negligence or willful  misconduct of the Agent or any Bank.
The  obligations  of each  Borrower  hereunder  shall be  complete  and  binding
forthwith  upon the  execution  of this  Agreement  and subject to no  condition
whatsoever, precedent or otherwise, and notice of acceptance hereof or action in
reliance hereon shall not be required.

     10.20 Confidentiality . The Banks and the Agent shall hold all confidential
information  obtained  pursuant to the  requirements of this Agreement which has
been  identified  as such by any  Borrower in  accordance  with their  customary
procedures  for  handling  confidential   information  of  this  nature  and  in
accordance  with  safe and  sound  banking  practices  and in any event may make
disclosure to its examiners,  affiliates,  outside  auditors,  counsel and other
professional  advisors  in  connection  with  this  Agreement  or as  reasonably
required by any bona fide  transferee  or  participant  in  connection  with the
contemplated  transfer  of any Note or  participation  therein or as required or
requested by any governmental  agency or  representative  thereof or pursuant to
legal process.  Without limiting the foregoing,  it is expressly understood that
such confidential  information shall not include  information which, at the time
of disclosure is in the public domain or, which after  disclosure,  becomes part
of the public  domain or  information  which any Bank or the Agent had  obtained
prior to the time of disclosure  and  identification  by any Borrower under this
Section  10.20,  or  information  received by any Bank or the Agent from a third
party. Nothing in this Section 10.20 or otherwise shall prohibit any Bank or the
Agent from  disclosing  any  confidential  information to the other Banks or the
Agent or render any of them liable in connection with any such disclosure.
