              ST. MARY LAND & EXPLORATION COMPANY AND SUBSIDIARIES
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                   (UNAUDITED)


                                  June 30, 1998


Note 1 - Basis of Presentation

The accompanying unaudited condensed consolidated financial statements have been
prepared in accordance with generally accepted accounting principles for interim
financial information. They do not include all information and notes required by
generally  accepted  accounting  principles for complete  financial  statements.
However,  except as disclosed  herein,  there has been no material change in the
information disclosed in the notes to consolidated financial statements included
in the Annual  Report on Form 10-K of St.  Mary Land &  Exploration  Company and
Subsidiaries  (the  "Company")  for the year ended  December  31,  1997.  In the
opinion of Management, all adjustments (consisting of normal recurring accruals)
considered  necessary  for a fair  presentation  have been  included.  Operating
results for the periods presented are not necessarily  indicative of the results
that may be expected for the full year.

The accounting  policies  followed by the Company are set forth in Note 1 to the
Company's  financial  statements  in Form 10-K for the year ended  December  31,
1997. It is suggested  that these  financial  statements be read in  conjunction
with the financial statements and notes included in the Form 10-K.

Certain  amounts  in  the  1997  consolidated  financial  statements  have  been
reclassified to correspond to the 1998 presentation.

Note 2 - Investments

The Company,  through  subsidiaries,  owned an 18% interest in a venture that is
developing the  Chernogorskoye  oil field in western Siberia (the "Russian joint
venture"). The Company accounted for its investment in the Russian joint venture
under the equity method of  accounting.  In February  1997, the Company sold its
interest  in the  Russian  joint  venture  to Khanty  Mansiysk  Oil  Corporation
("KMOC"),  formerly known as Ural Petroleum Corporation.  In accordance with the
Acquisition  Agreement,  the Company  received cash  consideration of $5,608,000
before  transaction  costs,  KMOC  common  stock  valued  at  $1,869,000,  and a
receivable in a form equivalent to a retained  production payment of $10,134,000
plus interest at 10% per annum from the limited liability company formed to hold
the Russian joint venture interest.  The Company's  receivable is collateralized
by the partnership  interest sold. The Company has the right, subject to certain
conditions,  to require KMOC to purchase the Company's  receivable  from the net
proceeds of an initial  public  offering of KMOC common stock or  alternatively,
the Company may elect to convert  all or a portion of its  receivable  into KMOC
common  stock  immediately  prior to an initial  public  offering of KMOC common
stock.  The  Company  recorded a gain on the sale of the Russian  joint  venture
interest of  $9,671,000.  The  Company's  equity in income for the Russian joint
venture for 1997 through the date of sale was $203,000.

The  Company  accounts  for  its  37%  ownership   interest  in  Summo  Minerals
Corporation ("Summo") under the equity method of accounting.  For the six months
ended June 30,  1998,  the Company  recorded a loss of $571,000 as its equity in
the losses of Summo.  In May 1997,  the Company  entered  into an  agreement  to
receive a 55% interest in Summo's Lisbon Valley Copper  Project (the  "Project")
in  return  for  the  Company  contributing  $4,000,000  in  cash,  all  of  its
outstanding  stock in Summo,  and  $8,600,000  in  letters of credit to a single
purpose company, Lisbon Valley Mining Company LLC, formed to own and operate the
Project.  Summo will contribute the property, all project permits and contracts,


                                       7
<PAGE>

$3,200,000 in cash, and a commitment for $45,000,000 of senior debt financing in
return  for a 45%  interest  in the new  company.  The  agreement  is subject to
certain  conditions,  including  final  resolution of  regulatory  approvals and
project  financing.  Summo has  completed  tests of the ground water  quality to
address concerns raised on appeal during the permitting process.  The results of
these tests support the original  conclusions  and  recommendations  made by the
Bureau of Land  Management when the Project was initially  approved.  A decision
from the Interior Board of Land Appeals is expected  before the end of 1998. The
Company has agreed to provide  interim  financing  of up to  $2,950,000  for the
Project in the form of a loan to Summo due in June 1999. Interest accrues on the
amounts  outstanding at the prime rate plus 1%. As of June 30, 1998,  $2,647,000
was outstanding under this loan.  Additional  amounts totaling $48,000 have been
advanced to Summo under this loan since June 30, 1998. At the Company's  option,
any principal and interest  amounts  outstanding are convertible  into shares of
Summo common stock anytime after December 31, 1998, at a conversion  price equal
to the weighted  average  trading price of Summo's  common shares for the twenty
trading days leading up to and including December 31, 1998. Upon  capitalization
of the new company the  outstanding  loan principal  shall  constitute a capital
contribution in partial  satisfaction of the Company's  capital  commitments set
out in the May 1997  agreement,  and any  accrued  interest on the loan shall be
forgiven.   Although  current  copper  prices  are  not  sufficient  to  warrant
development  of the  Project at this time,  management  believes  the  long-term
outlook for copper prices is favorable and plans to continue  providing  interim
financing during 1998 until Summo receives regulatory approval and copper prices
recover adequately to justify construction using permanent financing.  There can
be no  assurance  that the Company will  realize a return on its  investment  in
Summo or the Project.

Note 3 - Capital Stock

On February 26, 1997, the Company closed the sale of 2,000,000  shares of common
stock at $25.00 per share.  On March 12, 1997, the Company closed the sale of an
additional  180,000  shares  pursuant  to  the  underwriters'  exercise  of  the
over-allotment  option. These transactions resulted in aggregate net proceeds of
$51,200,000.   The  proceeds  were  used  to  fund  the  Company's  exploration,
development and acquisition  programs and to repay  borrowings  under its credit
facility.

In June 1998, the Company's  shareholders approved an amendment to the Company's
Certificate  of  Incorporation  to increase the number of  authorized  shares of
Common Stock from 15,000,000 to 50,000,000.

Note 4 - Recently Issued Accounting Standards

In June 1997, the Financial Accounting Standards Board ("FASB") issued Statement
of Financial  Accounting  Standards ("SFAS") No. 130,  "Reporting  Comprehensive
Income,"  effective for financial  statements for fiscal years  beginning  after
December 15, 1997. The Statement establishes standards for reporting and display
of comprehensive income and its components in financial statements. The adoption
of this  statement  will not have a material  impact on the Company's  financial
statements.

In June 1997,  the FASB issued SFAS No. 131,  "Disclosures  about Segments of an
Enterprise  and Related  Information,"  effective for financial  statements  for
fiscal years beginning after December 15, 1997. The Statement requires companies
to report  certain  information  about  operating  segments  in their  financial
statements  and certain  information  about their  products  and  services,  the
geographic areas in which they operate and their major customers. The Company is
currently reviewing the effects of the disclosure requirements of the Statement.



                                       8
<PAGE>

In February 1998, the FASB issued SFAS No. 132,  "Employer's  Disclosures  about
Pensions  and  Other  Postretirement   Benefits,"  effective  for  fiscal  years
beginning  after  December 15, 1997. The Statement  standardizes  the disclosure
requirements  for  pensions  and  other   postretirement   benefits  to  provide
information  that is more  comparable  and  concise.  The  Company is  currently
reviewing the effects of the disclosure requirements of the Statement.

In June  1998,  the  FASB  issued  SFAS  No.  133,  "Accounting  for  Derivative
Instruments and Hedging Activities," effective for all fiscal quarters of fiscal
years  beginning after June 15, 1999. The Statement  establishes  accounting and
reporting  standards for derivative  instruments,  including certain  derivative
instruments embedded in other contracts, and for hedging activities. The Company
is currently  reviewing  the effects this  Statement  will have on the financial
statements in relation to the Company's hedging activities.

Note 5 - Earnings per Share

In February  1997,  the FASB issued SFAS No. 128,  "Earnings  Per Share,"  which
requires a dual  presentation  of basic and  diluted  earnings  per  share.  The
Company  adopted SFAS No. 128  effective  December 31, 1997.  Under SFAS No. 128
basic net income per share of common stock is  calculated by dividing net income
by the weighted  average of common shares  outstanding  during each period,  and
diluted  net income per common  share of stock is  calculated  by  dividing  net
income by the weighted  average of outstanding  common shares and other dilutive
securities.  Dilutive  securities of the Company consist entirely of outstanding
options to  purchase  the  Company's  common  stock.  The  outstanding  dilutive
securities for the three-month  periods ended June 30, 1998 and 1997 were 95,255
and 108,421,  respectively,  and the  outstanding  dilutive  securities  for the
six-month  periods  ended  June 30,  1998  and 1997  were  118,861  and  97,361,
respectively. All net income of the Company is available to common stockholders.
The  adoption  of SFAS No.  128 had no effect on  diluted  net  income per share
compared to fully  diluted  net income per share as reported  for the six months
ended June 30, 1997.  Restated diluted net income per share for the three months
ended June 30, 1997 was $0.54  compared to fully diluted net income per share of
$0.53 as reported.  Restated basic net income per share for the six months ended
June 30,  1997 was $1.71  compared  to primary  net income per share of $1.69 as
reported.  Restated  basic net income per share for the three  months ended June
30,  1997 was  $0.54  compared  to  primary  net  income  per  share of $0.53 as
reported.

Note 6 - Income Taxes

Federal  income tax expense for 1998 and 1997 differs from the amount that would
be provided by applying the  statutory  U.S.  Federal  income tax rate to income
before income taxes primarily due to Section 29 credits and percentage depletion
in 1998 and the effect of state income taxes partially  offset by Section 29 tax
credits and percentage depletion in 1997.

Note 7 - Long-Term Debt and Notes Payable

On June 30, 1998,  the Company  entered into a new  long-term  revolving  credit
agreement  that replaced the agreement  dated March 1, 1993 and amended in April
1996. The new credit  agreement  specifies a maximum loan amount of $200,000,000
and has an initial  aggregate  borrowing  base of  $115,000,000.  The lender may
periodically  re-determine  the aggregate  borrowing base. The initial  accepted
borrowing  base is  $40,000,000.  The credit  agreement  has a maturity  date of
December 31, 2005, and includes a revolving  period that matures on December 31,
2000.  The Company can elect to allocate up to 50% of available  borrowings to a
short-term  tranche  due in 364 days.  The  Company  must  comply  with  certain
covenants including maintenance of stockholders' equity at a specified level and
limitations  on additional  indebtedness.  As of June 30, 1998  $19,200,000  was
outstanding under this credit agreement.



                                       9

Effective June 30, 1998,  interest on borrowings during the revolving period and
commitment  fees on the  unused  portion  of the  accepted  borrowing  base  are
calculated as follows:

At June 30, 1998,  the Company's debt to  capitalization  ratio as defined under
the credit agreement was 0.18 to 1.0.

Panterra, in which the Company has a 74% general partnership ownership interest,
has a separate credit  facility with a $25,000,000  borrowing base as of July 1,
1998,  and  $10,000,000  and  $11,000,000  outstanding  as of June 30,  1998 and
December 31, 1997,  respectively.  In June 1997,  Panterra entered into a credit
agreement replacing a previous agreement,  which was due March 31, 1999. The new
credit agreement  includes a two-year revolving period converting to a five-year
amortizing loan on June 30, 1999.  During the revolving period of the loan, loan
balances accrue interest at Panterra's option of either the bank's prime rate or
LIBOR plus 3/4% when the  Partnership's  debt to partners' capital ratio is less
than 30%,  up to a maximum of either the bank's  prime rate or LIBOR plus 1-1/4%
when the Partnership's debt to partners' capital ratio is greater than 100%.

ITEM 2.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF
         FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Overview

St. Mary Land & Exploration Company ("St. Mary" or the "Company") was founded in
1908 and  incorporated  in  Delaware  in 1915.  The  Company  is  engaged in the
exploration,  development,  acquisition  and production of crude oil and natural
gas with  operations  focused in five core operating areas in the United States:
The Mid-Continent  region; the ArkLaTex region;  south Louisiana;  the Williston
Basin; and the Permian Basin.

Internal  exploration,  drilling and production  personnel conduct the Company's
activities in the  Mid-Continent  and ArkLaTex  regions and in south  Louisiana.
Activities  in the  Williston  Basin are conducted  through  Panterra  Petroleum
("Panterra") in which the Company owns a 74% general partnership  interest.  The
Company proportionally consolidates its interest in Panterra.  Activities in the
Permian  Basin  are  primarily  contracted  through  an  oil  and  gas  property
management company with extensive experience in the basin.

St.  Mary has two  principal  equity  investments,  Summo  Minerals  Corporation
("Summo"), a North American copper mining company of which the Company owns 37%,
and until early 1997, the Company's Russian joint venture.  The Company accounts
for its  investments  in Summo and the Russian  joint  venture  under the equity
method and includes  its share of the income or loss from these  entities in its
consolidated  results of  operations.  Effective  February 12, 1997, the Company
sold its Russian joint venture.

The Company  receives  significant  royalty income from its south  Louisiana fee
lands.  Management  believes the Company's  royalty  income may increase in 1998
with the  completion  of the St.  Mary  Land &  Exploration  No. 3 well at South
Horseshoe  Bayou in January 1998 which  followed the completion of the discovery
well in the prospect in February 1997 and its subsequent  recompletion  in April
1998.  The Company  owns a 25% working  interest and royalty  interests  between
approximately  19% and 22% in this field for combined  net revenue  interests of
between  approximately  37% and 40%,  depending on the depth of production.  The
Company and the lessees have identified several geologic  objectives for testing
in future years.

During 1995,  1996 and 1997 the Company  acquired  proved oil and gas properties
for  a  total  of  $56.4  million.  The  results  of  operations  include  these
acquisitions and the subsequent development of the properties. In December 1995,
the Company  acquired  two  different  interests  in the Box Church Field in its
ArkLaTex  region for $2.2 million and several  additional  interests in 1996 for
$580,000. Development of the field has occurred with the drilling and completion
of three wells in 1996 and eleven  wells in 1997.  In the first half of 1998 the
Company  completed two of the three wells in progress at year-end  1997.  Two of
the five wells  anticipated to be drilled in 1998 to complete the development of
the field were in progress  as of June 30,  1998.  The  Company  purchased a 90%
interest in the producing  properties of Siete Oil & Gas  Corporation  for $10.0
million in June 1996 and completed a series of follow-on acquisitions of smaller
interests in these  properties  totaling $5.8 million during 1996,  1997 and the
first two quarters of 1998. These properties are located in the Permian Basin of
New Mexico and west Texas. The successful implementation of a secondary recovery
plan during the first half of 1998 was completed as part of the  Company's  plan
to further develop these properties.  Management  expects to acquire  additional
interests in the Siete  properties as they become  available.  In May 1997,  the
Company  acquired an 85% working  interest in certain  Louisiana  properties  of
Henry  Production  Company  for $3.8  million.  In  November  1997,  the Company
acquired  the  interests  of Conoco,  Inc.  in the  Southwest  Mayfield  area in
Oklahoma for $20.3 million.  Management  anticipates  drilling  several wells in
1998 to test the geologic  ideas  identified at the time of  acquisition of this
field, one such well was in progress at June 30, 1998. During the second quarter
of 1998, the Company entered into an exploration  and development  joint venture
in  east  Texas,  which  included  the  acquisition  of  interests  in  existing
properties for $521,000. Several smaller acquisitions were also completed during
1997 and 1996 totaling $560,000 and $2.8 million, respectively.



                                       11
<PAGE>

In February  1997, the Company sold its interest in the Russian joint venture to
Khanty  Mansiysk Oil  Corporation  ("KMOC"),  formerly  known as Ural  Petroleum
Corporation, for $17.6 million. The Company received $5.6 million in cash before
transaction  costs,  $1.9  million  of  KMOC  common  stock  and  a  convertible
receivable  in a form  equivalent  to a  retained  production  payment  of $10.1
million plus interest at 10% per annum from the limited liability company formed
to hold the Russian joint venture interest.

In February  1997,  the Company  closed the sale of  2,000,000  shares of common
stock at $25.00 per share and closed the sale of an additional 180,000 shares in
March 1997, pursuant to the underwriters' exercise of the over-allotment option.
These transactions resulted in aggregate net proceeds of $51.2 million.

In May 1997, the Company sold its non-operated interests in south Texas for $5.4
million  as part  of its  continuing  strategy  to  focus  and  rationalize  its
operations.

The Company  seeks to protect its rate of return on  acquisitions  of  producing
properties by hedging up to the first 24 months of an  acquisition's  production
at  prices  approximately  equal  to  those  used in the  Company's  acquisition
evaluation  and  pricing  model.  The Company  also  periodically  uses  hedging
contracts  to  hedge  or  otherwise  reduce  the  impact  of oil and  gas  price
fluctuations on production.  The Company's strategy is to ensure certain minimum
levels of  operating  cash flow and to take  advantage  of windows of  favorable
commodity  prices.  The Company generally limits its aggregate hedge position to
no more than 50% of its total  production.  The Company seeks to minimize  basis
risk and indexes the majority of its oil hedges to NYMEX prices and the majority
of its gas hedges to various regional index prices  associated with pipelines in
proximity  to the  Company's  areas of gas  production.  The  Company has hedged
approximately  3.2 million  MMBtu of its  remaining  1998 gas  production  at an
average fixed price of $2.20 per MMBtu.  The Company has also purchased  options
resulting in price  collars and price floors on 840,000  MMBtu of the  Company's
remaining  1998 gas production  with price ceilings  between $2.65 and $2.80 per
MMBtu and price floors  between $1.95 and $2.00 per MMBtu.  All of the Company's
existing oil hedges  matured  during the second quarter of 1998. The company has
not hedged any of its remaining 1998 oil production as of June 30, 1998.

This  Quarterly  Report on Form 10-Q  includes  certain  statements  that may be
deemed to be  "forward-looking  statements" within the meaning of Section 27A of
the  Securities  Act of 1933,  as amended,  and  Section  21E of the  Securities
Exchange Act of 1934,  as amended.  All  statements,  other than  statements  of
historical facts, included in this Form 10-Q that address activities,  events or

Oil and Gas Production Revenues.  Oil and gas production revenues increased $4.9
million,  or 32% to $20.2 million for the second  quarter 1998 compared to $15.3
million for the second quarter 1997. Oil  production  volumes  increased 34% and
gas  production  volumes  increased 31% for the second  quarter 1998 compared to
1997.  Average net daily production reached 17.4 MBOE in the second quarter 1998
compared  to 13.2  MBOE in the  comparable  quarter  of  1997.  This  production
increase resulted from new properties acquired and drilled during the past year.
Major  acquisitions  included the Southwest Mayfield  properties  purchased from
Conoco, the acquisition of Louisiana  properties from Henry Production  Company,
and the  additional  interests  purchased  in the Siete  properties.  Successful
drilling  results in the Box Church  Field in Texas,  the  Haynesville  Field in
Louisiana and in the Company's Oklahoma drilling program also contributed to the
second quarter 1998 production increase. Also contributing to the second quarter
1998 production increase were gas balancing  adjustments and other non-recurring
adjustments which increased average daily production for the quarter by 1.1MBOE.
The average  realized  oil price for the second  quarter 1998  decreased  28% to
$13.55 per Bbl, while  realized gas prices  increased 15% to $2.10 per Mcf, from
their respective 1997 levels.

Oil and gas production  revenue  increased $2.9 million,  or 8% to $39.2 million
for the six months ended June 30, 1998  compared to $36.3  million in 1997.  Oil
production  volumes  increased 21% and gas production  volumes increased 24% for
the first six months of 1998 compared with the comparable  1997 period.  Average
net  daily  production  was 16.4 MBOE for the six  months  ended  June 30,  1998
compared  to 13.3  MBOE in 1997.  This  production  increase  resulted  from new
properties acquired and drilled during the past year,  including the acquisition
of the Southwest  Mayfield  properties in Oklahoma and the Louisiana  properties
purchased from Henry Production Company.  Successful drilling results in the Box
Church  Field in Texas,  the South  Horseshoe  Bayou and  Haynesville  fields in
Louisiana and the Company's  Oklahoma drilling program  contributed to the first
half of 1998  production  increases.  The  average  oil price for the six months
ended June 30, 1998 decreased 28% to $14.18 per barrel, and gas prices decreased
5% to $2.16 per Mcf, from their respective 1997 levels.

The Company hedged 30,000 Bbls of its oil  production  during the second quarter
1998 at an average NYMEX price of $17.95 per Bbl. The Company  purchased options
resulting in price collars and price floors on 22,000 Bbls of its second quarter
1998 oil production  with a price ceiling of $24.00 per Bbl and a price floor of
$20.00 per Bbl. The Company realized a $313,000  increase in oil revenue or $.45
per Bbl for 1998 on these contracts  compared to a $219,000 decrease or $.38 per
Bbl in 1997.  The Company  also hedged 2.0 million  MMBtu of its second  quarter
1998 gas production at an average indexed price of $2.21 per MMBtu and purchased
options  resulting in price collars and price floors on 1.1 million MMBtu of its
second quarter 1998 gas production  with price ceilings  between $2.55 and $3.00
per MMBtu and price  floors  between  $1.95  and $2.00 per  MMBtu.  The  Company
realized a $324,000 increase in gas revenues or $.02 per Mcf for 1998 from hedge
contracts compared to a $1.0 million or $.10 per Mcf decrease in 1997.

Oil and Gas  Production  Costs.  Oil and gas  production  costs consist of lease
operating  expense and production  taxes.  Total production costs increased $1.1
million or 34% for the second quarter 1998 from comparable  1997 levels.  Higher
lease  operating  expenses were partially  offset by lower  production  taxes on
wells drilled in 1998 qualifying for reduced production tax rates. Total oil and
gas production costs per BOE increased 1% to $2.64 in 1998 compared to $2.60 per
BOE in the second quarter 1997.

Total  production  costs  increased $1.0 million or 14% for the six months ended
June 30, 1998 to $8.1 million as a result of new properties acquired and drilled
during the past year.  However,  total  production  costs per BOE declined 7% to
$2.74 for the six  months  ended  June 30,  1998  compared  to $2.95 for the six
months ended June 30, 1997,  primarily due to lower lease operating expenses per
BOE from high volume properties such as South Horseshoe Bayou.

Depreciation,  Depletion, Amortization and Impairment.  Depreciation,  depletion
and amortization expense ("DD&A") increased $2.5 million, or 62% to $6.5 million
in the second  quarter 1998  compared  with $4.0  million in 1997.  DD&A per BOE
increased  23% to $4.12 in the second  quarter  1998  compared to $3.36 in 1997.
This  increase  resulted from  increased  production  volumes of new  properties
acquired  and drilled in the last half of 1997 and the first half of 1998 with a
higher cost basis,  and from increased water production at South Horseshoe Bayou
and the adverse  impact of low oil prices in the  Williston  Basin.  The Company
recorded  impairments  of proved oil and gas  properties  of $1.1 million in the
second quarter 1998 compared with $516,000 in the comparable 1997 period.  These
second quarter 1998 charges  resulted from a high cost marginal well in Oklahoma
and another in Louisiana, as well as $580,000 of impairments associated with the
Company's properties in the Williston Basin due to low oil prices.



                                       14
<PAGE>

DD&A  increased  48% to $11.9  million  for the six months  ended June 30,  1998
compared with $8.0 million in 1997 because of increased  production  and reserve
declines from low oil prices and water  production at South Horseshoe Bayou, and
due to higher cost properties in four fields in Oklahoma. DD&A per BOE increased
to $4.01  in the six  months  ended  June 30,  1998  compared  to $3.33 in 1997.
Impairment  of  producing  oil and gas  properties  was $1.4 million for the six
months  ended June 30, 1998  compared to $516,000  for the six months ended June
30,  1997,  due to marginal  wells  drilled in Oklahoma  and  Louisiana  and the
adverse affects of low oil prices in the Williston Basin.

Abandonment and impairment of unproved properties  decreased $20,000 to $312,000
in the second quarter 1998 compared to $332,000 in 1997.

Abandonment and impairment of unproved properties increased $133,000 to $615,000
in the six months  ended June 30, 1998  compared  to $482,000 in the  comparable
period in 1997 due to  additional  lease  expirations  during  the first half of
1998.

Exploration.  Exploration  expense increased $1.4 million or 87% to $3.1 million
for the second  quarter 1998 compared  with $1.6 million in 1997  primarily as a
result of three unsuccessful exploratory wells in south Louisiana and Oklahoma.

Exploration  expense  increased $3.5 million or 114% to $6.5 million for the six
months  ended  June  30,  1998  compared  to $3.0  million  in  1997  due to six
unsuccessful  exploratory  tests in south Louisiana and Oklahoma and the payment
of $795,000 for delay rentals in the Company's  Atchafalaya prospect area in the
six months ended June 30, 1998 compared with 1997.

General and Administrative. General and administrative expenses declined $70,000
or 5% to $1.5 million for the second quarter 1998 as compared to 1997. Increased
compensation   and  rent   expenses   were  offset  by  declines  in  charitable
contributions, insurance and general corporate expenses.

General and administrative expenses decreased $144,000 or 3% to $4.4 million for
the six months ended June 30, 1998  compared to $4.6 million in 1997.  Increased
compensation   and  rent   expenses   were  offset  by  declines  in  charitable
contributions,  insurance  and  general  corporate  expenses  and  increases  in
overhead  reimbursements  from outside interest owners in properties operated by
the Company.

Other  operating  expenses  consist of legal expenses in connection with ongoing
oil and gas activities and oversight of the Company's mining  investments.  This
expense  decreased  $13,000 to $58,000 in the second  quarter 1998 compared with
the second quarter 1997.

Other operating  expenses increased $56,000 to $92,000 in the first half of 1998
compared to the comparable 1997 period,  primarily due to legal expenses in 1998
associated  with the pending  litigation  that seeks to recover damages from the
drilling  contractor  for the St.  Mary Land &  Exploration  No. 1 well at South
Horseshoe Bayou, and due to the benefit of a non-recurring insurance recovery of
$68,000 in 1997.

Equity in  Income of  Russian  Joint  Venture.  The  Company  accounted  for its
investment in the Russian joint venture under the equity method and included its
share of income from the venture in its results of operations up to the point of
sale.  Therefore  no equity in the net income of the Russian  joint  venture was
recorded in 1998  compared to $203,000  recorded  in 1997.  As  discussed  under
Outlook,  the Company  sold this  investment  in February  1997  resulting  in a
partial year of equity income recorded in 1997.



                                       15

Equity in Loss of Summo  Minerals  Corporation.  The  Company  accounts  for its
investment  in Summo under the equity  method and  includes its share of Summo's
income or loss in its results of  operations.  The  Company's  equity in the net
loss of Summo was $509,000 in the second quarter 1998 and $110,000 in 1997. This
increase  is  primarily  due to the  $447,000  impact  of  Summo's  decision  to
write-off its investment in its Cashin and Champion properties.

The  Company's  equity in the net loss of Summo was  $571,000 for the six months
ended June 30,  1998  compared to  $209,000  in 1997,  primarily  due to Summo's
decision to write-off its  investment  in its Cashin and Champion  properties in
the second quarter 1998.

Non-Operating  Income and Expense.  Interest income increased  $83,000 or 29% to
$372,000 for the second  quarter 1998 from $289,000 for the second  quarter 1997
due to $312,000 of interest  income  resulting  from a favorable  gas  balancing
decision by the Oklahoma Supreme Court.  Interest expense increased  $218,000 or
152% to $361,000 for the second  quarter  1998  compared to $143,000 in the 1997
period due to increased  borrowings  under the Company's and  Panterra's  credit
facilities in 1998. Debt under the Company's  credit facility had been repaid in
the first quarter 1997 with the proceeds  from the sale of the Company's  common
stock in February 1997.

Interest  income  increased  $59,000 or 13% to $526,000 in the six month  period
ended June 30, 1998 compared to $467,000 for the  comparable  1997 period due to
$312,000 of interest  income from the favorable gas balancing  decision in 1998.
Interest  was  earned  in the  six-month  period  ended  June 30,  1997 on funds
available from the sale of the Company's common stock.  Interest expense for the
six months ended June 30, 1998 increased  $29,000 or 4% to $754,000  compared to
$725,000 for 1997 due to borrowings  under  Panterra's and the Company's  credit
facilities.

Income Taxes. Income tax expense was $1.1 million in the second quarter 1998 and
$3.0  million  in 1997,  resulting  in  effective  tax rates of 35.5% and 35.2%,
respectively.  This reduced  expense  reflects lower net income from  operations
before income taxes for 1998 due to lower oil prices,  increased exploration and
DD&A expenses and a $4.2 million pre-tax gain on the sale of non-core properties
in south Texas in the second quarter 1997.

Income tax expense  decreased  $7.6  million to $1.9  million for the six months
ended  June  30,  1998,  primarily  resulting  from  lower  oil and gas  prices,
increased  exploration  expense and DD&A expenses in 1998,  and the $9.7 million
and $4.2 million gains on the sales of the  Company's  Russian joint venture and
non-core properties,  respectively,  in 1997. The effective tax rate for the six
months  ended June 30,  1998  decreased  to 33.8%  compared to 35.6% in the 1997
period.

Net Income. Net income for the second quarter 1998 decreased $3.8 million or 65%
to $2.1 million  compared to $5.9  million in 1997.  Increases of 31% and 34% in
gas and oil  volumes,  respectively,  partially  offset by a 28% decrease in oil
prices  resulted in a $4.9 million  increase in oil and gas production  revenues
for the  second  quarter  1998.  A $4.2  million  gain on the  sale of  non-core
properties in the second  quarter 1997,  increases in  exploration  expenses and
DD&A associated with increased  production  volumes and impairments of producing
properties in the second quarter 1998, contributed to a $3.6 million decrease in
income from continuing operations.

Net income for the six months  ended June 30, 1998  decreased  $13.7  million to
$3.7 million  compared to $17.5  million in 1997.  This  decrease  resulted from
increased  oil and gas  production,  offset  by  lower  oil and gas  prices  and
increases in exploration  expense,  DD&A and impairments of producing properties
in 1998, and from the $9.7 million gain on the sale of the Company's interest in
the Russian joint venture and the $4.2 million gain on the sale of the Company's
non-core south Texas properties in 1997.

Liquidity and Capital Resources

The  Company's  primary  sources of liquidity are the cash provided by operating
activities, debt financing and access to the capital markets. The Company's cash
needs  are for  the  acquisition,  exploration  and  development  of oil and gas
properties and for the payment of debt obligations,  trade payables, stockholder
dividends  and for the  repurchase of the  Company's  common stock.  The company
generally  finances its  exploration  and  development  programs from internally
generated  cash  flow,  bank  debt and cash and cash  equivalents  on hand.  The
Company  continually  reviews its capital expenditure budget based on changes in
cash flow and other factors.

Cash Flow.  The Company's net cash  provided by operating  activities  increased
$3.7  million  or 16% to $27.4  million in the six  months  ended June 30,  1998
compared to $23.7 million in 1997.  Increased  receipts for oil and gas revenues
due to higher  production  volumes,  despite  reduced oil and gas  prices,  were
offset by increased  payments  for lease  operating  expenses and  significantly
higher payments related to exploration expenses. Also, in the first half of 1997
the Company made a cash payment of approximately $1.6 million in satisfaction of
liabilities  previously  accrued by the Company under its SAR plan compared to a
corresponding payment of $351,000 in the first half 1998.

Net cash used in  investing  activities  in the six months  ended June 30,  1998
increased  $15.4  million or 88% to $32.8  million  compared to $17.4 million in
1997.  This  increase was  primarily  due to a $5.7 million  increase in capital
expenditures  for the  Company's  drilling  programs  in  1998,  a $5.4  million
decrease in  acquisition  expenditures  in 1998, $ 5.6 million in cash  received
from the sale of the  Company's  Russian joint venture in the first quarter 1997
and $7.1 million received in 1997 from the sale of oil and gas properties. Total
first half 1998  capital  expenditures,  including  acquisitions  of oil and gas
properties, were $31.4 million compared to $31.1 million in 1997.

The Company was able to apply the majority of the proceeds from the sales of oil
and gas  properties in 1997 to  acquisitions  of oil and gas  properties in 1997
allowing  tax-free  exchanges of these properties for income tax purposes.  In a
tax-free  exchange of properties the tax basis of the sold property carries over
to the new  property.  Gains  or  losses  for tax  purposes  are  recognized  by
amortization of the tax basis of the new property  throughout its remaining life
or when the new property is sold or abandoned.

Net cash  provided by  financing  activities  was $2.9  million in the six month
period ended June 30, 1998  resulting  from net borrowing of long-term  debt and
payments of dividends to shareholders compared to net cash provided by financing
activities of $14.0 million in the comparable 1997 period.  The Company received
$51.2  million  from  the  sale  of  common  stock  and had a net  reduction  of
borrowings of $35.7 million in the first quarter of 1997. The Company  increased
its  quarterly  dividend  25% to $.05 per  share  effective  with the  quarterly
dividend declared in January 1997 and paid in February 1997.

The Company had $4.5 million in cash and cash equivalents and working capital of
$3.6  million  as of June 30,  1998  compared  to $7.1  million of cash and cash
equivalents  and working  capital of $9.6  million at  December  31,  1997.  The
reduction in cash and cash  equivalents  is primarily the result of payments for
capital expenditures,  property  acquisitions and exploration  expenses,  and to
reduce debt levels.  Working capital  decreased due to the reduction in cash and
cash equivalents and decreased  accounts  receivable,  primarily for oil and gas
sales due to price declines,  offset by a smaller  decrease in accounts  payable
and accrued expenses resulting from drilling activity.

Credit  Facility.  On June 30, 1998,  the Company  entered into a new  long-term
revolving credit agreement replacing its credit facility dated March 1, 1993 and
amended April 1, 1996. The new credit facility provides a maximum loan amount of
$200.0  million.  The amount that may be borrowed  from time to time will depend
upon the value of the Company's  oil and gas  properties  and other assets.  The
Company's  borrowing base,  which is redetermined  annually,  was increased from
$40.0  million to $60.0  million in February  1997 and further  increased in May
1998 to $115.0 million based on increases in the Company's  estimated net proved
reserves in 1996 and 1997. The initial accepted borrowing base is $40.0 million.
The  maturity  date of the new credit  agreement  is December  31,  2005,  which
includes a revolving period maturing on December 31, 2000. The Company may elect
to allocate up to 50% of the available borrowings to a short-term tranche due in
364  days.  Outstanding  revolving  loan  balances  under the  Company's  credit
facility,  which  were $19.2  million  and $14.5  million  at June 30,  1998 and
December 31, 1997,  respectively,  accrue  interest at rates  determined  by the
Company's debt to total capitalization ratio. During the revolving period of the
loan, loan balances  accrue  interest at the Company's  option of either (a) the
higher of the banks' prime rate or the Federal Funds Rate plus 1/2% or (b) LIBOR
plus 1/2% when the Company's debt to total  capitalization  is less than 30%, up
to a maximum  of the  Company's  option of either  (a) the  higher of the banks'
prime  rate  plus 1/8% or the  Federal  Funds  Rate plus 5/8% or (b) LIBOR  plus
1-1/4%  when the  Company's  debt to total  capitalization  ratio is equal to or
exceeds 50%. The credit  facility  provides for,  among other things,  covenants
requiring maintenance of stockholders' equity at a specified level and limits on
additional indebtedness of the Company.

Panterra, in which the Company has a 74% general partnership ownership interest,
has a separate credit facility with a $25.0 million borrowing base as of July 1,
1998,  and $10.0 million and $11.0 million  outstanding  as of June 30, 1998 and
December 31, 1997,  respectively.  In June 1997,  Panterra entered into a credit
agreement replacing a previous agreement,  which was due March 31, 1999. The new
credit agreement  includes a two-year revolving period converting to a five-year
amortizing loan on June 30, 1999.  During the revolving period of the loan, loan
balances accrue interest at Panterra's option of either the bank's prime rate or
LIBOR plus 3/4% when the  Partnership's  debt to partners' capital ratio is less
than 30%,  up to a maximum of either the bank's  prime rate or LIBOR plus 1-1/4%
when the Partnership's debt to partners' capital ratio is greater than 100%. The
Company  intends to use the available  credit under the Panterra credit facility
to fund a portion of its 1998 capital expenditures in the Williston Basin.

Common Stock. In February 1997, the Company closed the sale of 2,000,000  shares
of common stock at $25.00 per share and closed the sale of an additional 180,000
shares  in  March  1997,   pursuant  to  the   underwriters'   exercise  of  the
over-allotment  option. These transactions resulted in aggregate net proceeds of
$51.2  million.  The  proceeds  of these  sales were used to fund the  Company's
exploration,  development  and acquisition  programs,  and pending such use were
used to repay borrowings under its credit facility.

In June 1998, the Company's  shareholders  approved an increase in the number of
authorized  shares of the  Company's  common stock from 15 million to 50 million
shares.

In August 1998, the Company's Board of Directors  authorized a stock  repurchase
program  whereby the  Company may  purchase  from  time-to-time,  in open market
purchases or  negotiated  sales,  up to one million  shares of its common stock.
Management anticipates that such purchases of shares by the Company may commence
at any time and will be funded with internal cash flow and borrowings  under the
Company's credit facility.

Outlook.  The Company  believes that its existing capital  resources,  cash flow
from operations and available  borrowings are sufficient to meet its anticipated
capital and operating requirements for 1998.



                                       18
<PAGE>

The Company has reduced its 1998 capital budget by  approximately  $11.0 million
to a revised total of  approximately  $83.0  million.  The reduction  reflects a
reallocation of capital to the Company's stock  repurchase  program as well as a
response to lower oil prices and drilling  results.  Reductions  of $3.0 million
arise from postponement of new drilling activities in the Williston Basin due to
low oil prices; $4.0 million due to suspension, pending further evaluation, of a
previously scheduled second deep test at the Company's Atchafalaya prospect; and
$4.0 million from  re-balancing of the drilling program in the Anadarko Basin to
emphasize less costly and lower risk prospects.

The amount and allocation of future capital and  exploration  expenditures  will
depend upon a number of factors  including  the number of available  acquisition
opportunities, the Company's ability to assimilate such acquisitions, the impact
of oil and gas prices on investment  opportunities,  the availability of capital
and the success of its development and exploratory  activity which could lead to
funding requirements for further development.

The Company continuously evaluates  opportunities in the marketplace for oil and
gas  properties  and,  accordingly,  may be a buyer or a seller of properties at
various times.

The Company has added  several new  prospects  to its  pipeline of large  target
exploration  ideas and expects to  commence  the  drilling of three  significant
tests  by the  first  quarter  of  1999 at its  Patterson,  Stallion  and  South
Horseshoe Bayou projects in South Louisiana.

Volatile industry  conditions and several exploration  disappointments  early in
the year are  combining  to make 1998 a  particularly  challenging  year for the
Company as it consolidates the rapid growth in reserves and production  achieved
during the past several years.  Modest continued growth in production volumes is
expected during the balance of the year as the Company's  Atchafalaya  discovery
is  brought  online in August  and  additional  wells in the  Mid-Continent  and
ArkLaTex regions are completed

The St. Mary Land & Exploration No. 3 (40 percent net revenue interest) at South
Horseshoe  Bayou was completed in January 1998 in the  17,300-foot  sand and has
experienced  increasing  water  production  since early June.  Cumulative  gross
production  to date totals  approximately  6.6 BCF of gas and 47,000  barrels of
condensate (approximately 2.6 BCF of gas and 18,800 barrels of condensate net to
the  Company).  Through  early  August  1998 the well has  continued  to produce
approximately  34 MMCF of gas and 200 barrels of  condensate  per day.  However,
water production has continued to increase and presently exceeds 900 barrels per
day.  The cause of this water  production  is unknown and the well's  production
trends are being closely monitored.

The net proved reserves  assigned to the  17,300-foot  sand in the No. 3 well at
year-end 1997 were 33.1 BCF of gas and 177,000  barrels of condensate.  Although
to date the water  production has not adversely  affected the well's  productive
capacity,  the ultimate impact on the Company's production and reserves at South
Horseshoe  Bayou can not be  determined  at this time.  Should water  production
continue to  increase  substantially,  the No. 3 well's  future  production  and
recoverable reserves could be materially impaired.

The Company's depreciation,  depletion and amortization rate per BOE is expected
to be somewhat  higher than  historical  amounts as the  Atchafalaya  production
comes online beginning in August 1998.

In May 1997, the Company  entered into an agreement to receive a 55% interest in
Summo's Lisbon Valley Copper  Project (the  "Project") in return for the Company
contributing  $4.0 million in cash, all of its outstanding  stock in Summo,  and
$8.6 million in letters of credit for  development  of the Project.  The Company
has agreed to provide  interim  financing of up to $2.95 million for the Project
in the form of a loan to Summo  due in June  1999.  As of June 30,  1998,  $2.65
million was outstanding  under this loan.  Additional  amounts  totaling $48,000
have been  advanced to Summo under this loan since June 30, 1998.  Any principal
and interest  amounts  outstanding are  convertible  into shares of Summo common
stock  anytime  after  December  31,  1998 at the  option of the  Company.  Upon
capitalization of the Project, the outstanding loan principal shall constitute a


                                       19
<PAGE>

capital   contribution  in  partial   satisfaction  of  the  Company's   capital
commitments set out in the May 1997 agreement.  Future development and financial
success of the  Project  are largely  dependent  on the market  price of copper,
which is determined in world markets and is subject to significant fluctuations.
Although current copper prices are not sufficient to warrant  development of the
Project at this time,  management  believes  the  long-term  outlook  for copper
prices is favorable and plans to continue  providing  interim  financing  during
1998 until Summo  receives final  regulatory  approval and copper prices recover
adequately to justify  construction using permanent  financing.  There can be no
assurance  that the Company will realize a return on its  investment in Summo or
the Project.

In February  1997,  the  Company  sold its Russian  joint  venture to KMOC.  The
Company  received  approximately  $5.6  million  in  cash  consideration  before
transaction costs, KMOC common stock valued at approximately $1.9 million, and a
receivable  in  a  form   equivalent  to  a  retained   production   payment  of
approximately  $10.1  million  plus  interest  at 10% per annum from the limited
liability  company  formed  to hold the  Russian  joint  venture  interest.  The
Company's  receivable is  collateralized  by the partnership  interest sold. The
Company  has the  right,  subject  to certain  conditions,  to  require  KMOC to
purchase the  Company's  receivable  from the net proceeds of an initial  public
offering of KMOC common stock or alternatively, the Company may elect to convert
all or a portion of its receivable into KMOC common stock  immediately  prior to
an initial public offering of KMOC common stock.

Impact of the Year 2000  Issue.  The Year 2000 Issue is the  result of  computer
programs being written using two digits rather than four, or other  methods,  to
define the applicable year. Computer programs that have date-sensitive  software
may recognize a date using "00" as the year 1900 rather than the year 2000. This
could  result in a system  failure or  miscalculations  causing  disruptions  of
operations,  including,  among other  things,  a temporary  inability to process
transactions, send invoices or engage in similar normal business activities.

The Company has  conducted a review of its computer  systems and has  determined
that the computer  system used by Panterra  will need to be replaced in order to
properly  utilize dates beyond  December 31, 1999.  Panterra,  after a review of
available replacement systems, is in contract negotiations to license a suitable
Year 2000 compliant system, and believes conversion can be completed, tested and
operational  before  December  31, 1999 at a cost that is not expected to have a
material  effect on the Company's  results of operations.  If replacement of the
Panterra  system is not  completed  timely,  the Year 2000  Issue  could  have a
significant impact on the operations of Panterra. The Company presently believes
that other less  significant  systems can be upgraded to mitigate  the Year 2000
Issue with  modifications  to existing  software or conversions to new software.
Modifications or conversions to new software for the less  significant  systems,
if not completed timely,  would have neither a material impact on the operations
of the Company nor on its results of operations.

The Company has initiated formal  communications with its significant  suppliers
and purchasers and  transporters  of oil and natural gas to determine the extent
to which the Company is vulnerable to those third parties'  failure to remediate
their own Year 2000 Issues.  There can be no guarantee that the systems of these
third parties will be converted  timely, or that a failure to convert by another
company would not have a material adverse effect on the Company.

Accounting Matters

In February  1997, the Financial  Accounting  Standards  Board  ("FASB")  issued
Statement of Financial  Accounting  Standards  ("SFAS") No. 128,  "Earnings  Per
Share," which  requires a dual  presentation  of basic and diluted  earnings per
share. The Company adopted SFAS No. 128 effective  December 31, 1997. Under SFAS
No. 128 basic net income per share of common stock is calculated by dividing net
income by the weighted  average of common shares  outstanding  during each year,
and  diluted  net income  per  common  share of common  stock is  calculated  by
dividing net income by the weighted  average of common shares and other dilutive
securities.



                                       20
<PAGE>

In June 1997, the FASB issued SFAS No. 130,  "Reporting  Comprehensive  Income,"
effective for financial statements for fiscal years beginning after December 15,
1997.  The  Statement   establishes  standards  for  reporting  and  display  of
comprehensive income and its components in financial statements. The adoption of
this  statement  will not have a  material  impact  on the  Company's  financial
statements.

In June 1997,  the FASB issued SFAS No. 131,  "Disclosures  about Segments of an
Enterprise  and Related  Information,"  effective for financial  statements  for
fiscal years beginning after December 15, 1997. The Statement requires companies
to report  certain  information  about  operating  segments  in their  financial
statements  and certain  information  about their  products  and  services,  the
geographic areas in which they operate and their major customers. The Company is
currently reviewing the effects of the disclosure requirements of the Statement.

In February 1998, The FASB issued SFAS No. 132,  "Employer's  Disclosures  about
Pensions  and  Other  Postretirement   Benefits,"  effective  for  fiscal  years
beginning  after  December 15, 1997. The Statement  standardizes  the disclosure
requirements  for  pensions  and  other   postretirement   benefits  to  provide
information  that is more  comparable  and  concise.  The  Company is  currently
reviewing the effects of the disclosure requirements of the Statement.

In June  1998,  the  FASB  issued  SFAS  No.  133,  "Accounting  for  Derivative
Instruments and Hedging Activities," effective for all fiscal quarters of fiscal
years  beginning after June 15, 1999. The Statement  establishes  accounting and
reporting  standards for derivative  instruments,  including certain  derivative
instruments embedded in other contracts, and for hedging activities. The Company
is currently  reviewing  the effects this  Statement  will have on the financial
statements in relation to the Company's hedging activities.

Effects of Inflation and Changing Prices

The Company's  results of operations  and cash flow are affected by changing oil
and gas prices.  Within the United States  inflation has had a minimal effect on
the Company.  The Company cannot  predict the extent of any such effect.  If oil
and gas prices increase,  there could be a corresponding increase in the cost to
the Company for drilling and related services, although offset by an increase in
revenues.  Should  oil and gas  prices  increase,  the cost of  acquisitions  of
producing  properties will increase,  which could limit the Company's ability to
acquire properties that meet the Company's criteria.

During the first half of 1998 the Company experienced an increase in the cost to
the Company for  drilling  and related  services  resulting  from  shortages  in
available  drilling  rigs,  drilling  and  technical  personnel,   supplies  and
services.  However,  since mid-year  service costs appear to have  stabilized or
begun to decline.  If shortages persist,  there could be continued  increases in
the cost to the Company of exploration, drilling and production of oil and gas.

Delaware.

         IN WITNESS  WHEREOF,  St. Mary Land and Exploration  Company has caused

                  ARTICLE II - The Loans and Letters of Credit
                               -------------------------------

         Section 2.1.  Commitments to Lend; Notes.

         (a) Tranche A Loans.  Subject to the terms and conditions hereof,  each
Lender agrees to make loans to Borrower (herein called such Lender's  "Tranche A
Loans") upon Borrower's request from time to time during the Tranche A Revolving
Period,  provided that (a) subject to Sections 3.3, 3.4 and 3.6, all Lenders are
requested  to make  Tranche A Loans of the same Type in  accordance  with  their
respective Percentage Shares and as part of the same Borrowing, (b) after giving
effect to such Tranche A Loans, the Tranche A Facility Usage does not exceed the
Tranche A  Borrowing  Base (as  defined in Section  2.10) and (c) the  Aggregate
Facility Usage does not exceed the Maximum Loan Amount.  The aggregate amount of
all Loans in any  Borrowing  of Tranche A Loans that are Base Rate Loans must be
greater than or equal to $100,000 or must equal the remaining availability under
the Tranche A Borrowing Base.  Borrower may have no more than five Borrowings of
Tranche A Loans that are Eurodollar Loans outstanding at any time. The aggregate
amount of all Loans in any  Borrowing  of  Tranche A Loans  that are  Eurodollar
Loans  must be greater  than or equal to  $500,000  or must equal the  remaining
availability  under the Tranche A Borrowing  Base. The obligation of Borrower to
repay to each  Lender the  aggregate  amount of all Tranche A Loans made by such
Lender,  together  with  interest  accruing in  connection  therewith,  shall be
evidenced by a single  promissory  note (herein called such Lender's  "Tranche A
Note")  made by  Borrower  payable  to the  order of such  Lender in the form of
Exhibit A-1 with  appropriate  insertions.  The amount of principal owing on any
Lender's  Tranche A Note at any given time shall be the aggregate  amount of all
Tranche A Loans  theretofore made by such Lender minus all payments of principal
theretofore  received  by such Lender on such  Tranche A Note.  Interest on each
Tranche A Note  shall  accrue  and be due and  payable  as  provided  herein and
therein.  Each  Tranche A Note shall be due and payable as  provided  herein and
therein,  and shall be due and payable in full on the  Tranche A Maturity  Date.
Subject to the terms and  conditions  hereof,  Borrower may borrow,  repay,  and
reborrow Tranche A Loans hereunder during the Tranche A Revolving Period.



                                       13

         (b) Tranche B Loans.  Subject to the terms and conditions hereof,  each
Lender agrees to make loans to Borrower (herein called such Lender's  "Tranche B
Loans") upon Borrower's request from time to time during the Tranche B Revolving
Period,  provided that (a) subject to Sections 3.3, 3.4 and 3.6, all Lenders are
requested  to make  Tranche B Loans of the same Type in  accordance  with  their
respective Percentage Shares and as part of the same Borrowing, (b) after giving
effect to such Tranche B Loans, the Tranche B Facility Usage does not exceed the
Tranche B  Borrowing  Base (as  defined in Section  2.10) and (c) the  Aggregate
Facility Usage does not exceed the Maximum Loan Amount.  The aggregate amount of
all Loans in any  Borrowing  of Tranche B Loans that are Base Rate Loans must be
greater than or equal to $100,000 or must equal the remaining availability under
the Tranche B Borrowing Base. The aggregate amount of all Loans in any Borrowing
of Tranche B Loans that are  Eurodollar  Loans must be greater  than or equal to
$500,000 or must equal the remaining  availability under the Tranche B Borrowing
Base.  Borrowers may have not more than three Borrowings of Tranche B Loans that
are  Eurodollar  Loans  outstanding  at any time.  The obligation of Borrower to
repay to each  Lender the  aggregate  amount of all Tranche B Loans made by such
Lender,  together  with  interest  accruing in  connection  therewith,  shall be
evidenced by a single  promissory  note (herein called such Lender's  "Tranche B
Note")  made by  Borrower  payable  to the  order of such  Lender in the form of
Exhibit A-2 with  appropriate  insertions.  The amount of principal owing on any
Lender's  Tranche B Note at any given time shall be the aggregate  amount of all
Tranche B Loans  theretofore made by such Lender minus all payments of principal
theretofore  received  by such Lender on such  Tranche B Note.  Interest on each
Tranche B Note  shall  accrue  and be due and  payable  as  provided  herein and
therein.  Each  Tranche B Note shall be due and payable as  provided  herein and
therein,  and shall be due and payable in full on the  Tranche B Maturity  Date.
Subject to the terms and  conditions  hereof,  Borrower may borrow,  repay,  and
reborrow Tranche B Loans hereunder.

         (c) At any time and from time to time  until  the end of the  Tranche A
Revolving  Period,  Borrower may elect,  subject to the approval of the Majority
Lenders in the exercise of their sole discretion,  to convert all or any portion
of the Tranche B Borrowing Base into the Tranche A Borrowing Base. Such election
shall be made in writing  delivered  to the Agent and,  if  approved by Lenders,
such  conversion  shall occur upon payment of the  conversion  fee  described in
Section  2.5(e) and execution by Borrower of amendments to the Loan Documents in
form  and  substance  satisfactory  to  Lenders.  Any  and all  such  conversion
elections  shall be in the amount of  $2,000,000  or more.  Notwithstanding  the
foregoing,  if such election is made  concurrently  with a determination  of the
Aggregate  Borrowing  Base, such election may be in any amount not to exceed the
limitations  set forth in this  Agreement  and shall not  require the payment of
such conversion fee.

         Section  2.2.  Requests  for New  Loans.  Borrower  must  give to Agent
written  notice (or  telephonic  notice  promptly  confirmed  in writing) of any
requested Borrowing of new Tranche A Loans or new Tranche B Loans to be advanced
by Lenders.  Each such notice  constitutes  a "Borrowing  Notice"  hereunder and
must:

         (a) specify (i) the aggregate  amount of any such Borrowing of new Base
Rate  Loans and the date on which such Base Rate  Loans are to be  advanced,  or
(ii) the aggregate  amount of any such  Borrowing of new Eurodollar  Loans,  the
date on which such Eurodollar Loans are to be advanced (which shall be the first
day of the  Interest  Period which is to apply  thereto),  and the length of the
applicable Interest Period; and

         (b) be received by Agent not later than 11:30 a.m., Dallas, Texas time,
on (i) the day on which  any such Base  Rate  Loans are to be made,  or (ii) the
third Business Day preceding the day on which any such  Eurodollar  Loans are to
be made.

Each such written request or confirmation must be made in the form and substance
of the "Borrowing  Notice"  attached hereto as Exhibit B, duly  completed.  Each
such   telephonic   request   shall  be  deemed  a   representation,   warranty,
acknowledgment and agreement by Borrower as to the matters which are required to
be set out in such  written  confirmation.  Upon  receipt of any such  Borrowing
Notice,  Agent shall give each Lender prompt notice of the terms thereof. If all
conditions  precedent  to such new Loans have been met,  each Lender will on the
date requested  promptly  remit to Agent at Agent's office in Dallas,  Texas the
amount  of such  Lender's  new Loan in  immediately  available  funds,  and upon



                                       14
<PAGE>

receipt of such funds,  unless to its actual knowledge any conditions  precedent
to such Loans have been neither met nor waived as provided  herein,  Agent shall
promptly make such Loans available to Borrower. Unless Agent shall have received
prompt  notice from a Lender that such Lender will not make  available  to Agent
such Lender's new Loan, Agent may in its discretion  assume that such Lender has
made such Loan available to Agent in accordance  with this section and Agent may
if it chooses,  in reliance upon such  assumption,  make such Loan  available to
Borrower.  If and to the  extent  such  Lender  shall  not so make  its new Loan
available to Agent, such Lender and Borrower  severally agree to pay or repay to
Agent  within  three days after  demand  the amount of such Loan  together  with
interest  thereon,  for each day from the date such amount was made available to
Borrower until the date such amount is paid or repaid to Agent, with interest at
(i) the Federal  Funds Rate,  if such Lender is making such payment and (ii) the
interest  rate  applicable at the time to the other new Loans made on such date,
if Borrower is making such repayment. If neither such Lender nor Borrower pay or
repay to Agent such amount within such three-day period, Agent shall in addition
to such  amount be entitled to recover  from such Lender and from  Borrower,  on
demand,  interest  thereon at the Default  Rate,  calculated  from the date such
amount was made available to Borrower. The failure of any Lender to make any new
Loan to be made by it  hereunder  shall  not  relieve  any  other  Lender of its
obligation  hereunder,  if any,  to make its new Loan,  but no  Lender  shall be
responsible  for the failure of any other Lender to make any new Loan to be made
by such other Lender.

         Section 2.3.  Continuations and Conversions of Existing Loans. Borrower
may make the following elections with respect to Loans already outstanding:  (a)
with respect to Tranche A Loans,  to convert  Tranche A Loans that are Base Rate

Loans to Tranche A Loans that are Eurodollar  Loans,  to convert Tranche A Loans
that are  Eurodollar  Loans to  Tranche A Loans  that are Base Rate Loans on the
last day of the Interest Period  applicable  thereto,  and to Continue Tranche A
Loans that are Eurodollar Loans beyond the expiration of such Interest Period by
designating a new Interest Period to take effect at the time of such expiration;
and (b) with  respect  to Tranche B Loans,  to convert  Tranche B Loans that are
Base Rate Loans to Tranche B Loans that are Eurodollar Loans, to convert Tranche
B Loans that are Eurodollar Loans to Tranche B Loans that are Base Rate Loans on
the last day of the Interest Period applicable thereto,  and to Continue Tranche
B Loans that are Eurodollar  Loans beyond the expiration of such Interest Period
by  designating  a new  Interest  Period  to  take  effect  at the  time of such
expiration.  In making such elections,  Borrower may combine  existing Tranche A
Loans made  pursuant to separate  Borrowings  into one new  Borrowing  or divide
existing  Tranche A Loans made  pursuant  to one  Borrowing  into  separate  new
Borrowings,  provided  that  Borrower may have no more than five  Borrowings  of
Tranche A Loans  that are  Eurodollar  Loans and three  Tranche B Loans that are
Eurodollars Loans  outstanding at any time. To make any such election,  Borrower
must give to Agent written notice (or telephonic  notice  promptly  confirmed in
writing)  of any such  conversion  or  continuation  of existing  Loans,  with a
separate  notice given for each new  Borrowing.  Each such notice  constitutes a
"Continuation/Conversion Notice" hereunder and must:

         (a)  specify the existing Loans which are to be Continued or converted;

         (b)  specify (i) the  aggregate  amount of any  Borrowing  of Base Rate
Loans into which such  existing  Loans are to be continued or converted  and the
date on which such continuation or conversion is to occur, or (ii) the aggregate
amount of any Borrowing of Eurodollar  Loans into which such existing  Loans are
to be Continued or converted,  the date on which such continuation or conversion
is to occur  (which  shall be the first day of the  Interest  Period which is to
apply to such  Eurodollar  Loans),  and the  length of the  applicable  Interest
Period; and

         (c) be received by Agent not later than 11:30 a.m., Dallas, Texas time,
on (i) the day on which any such  continuation  or conversion to Base Rate Loans
is to occur,  or (ii) the third Business Day preceding the day on which any such
continuation or conversion to Eurodollar Loans is to occur.

Each such written  request or  confirmation  must  contain the  substance of the
"Continuation/Conversion  Notice" attached hereto as Exhibit C, and be in a form
acceptable  to  Agent.   Each  such   telephonic   request  shall  be  deemed  a
representation,  warranty,  acknowledgment  and  agreement by Borrower as to the
matters  which are  required to be set out in such  written  confirmation.  Upon
receipt of any such Continuation/Conversion Notice, Agent shall give each Lender
prompt notice of the terms thereof. Each Continuation/Conversion Notice shall be
irrevocable  and binding on  Borrower.  During the  continuance  of any Default,
Borrower may not make any  election to convert  existing  Loans into  Eurodollar
Loans or Continue  existing Loans as Eurodollar  Loans. If (due to the existence
of a Default or for any other reason) Borrower fails to timely and properly give
any notice of continuation or conversion with respect to a Borrowing of existing
Eurodollar  Loans at least  three days prior to the end of the  Interest  Period
applicable thereto,  such Eurodollar Loans shall automatically be converted into
Base Rate Loans at the end of such Interest Period. No new funds shall be repaid
by Borrower or advanced by any Lender in  connection  with any  continuation  or
conversion of existing Loans pursuant to this section,  and no such continuation
or conversion shall be deemed to be a new advance of funds for any purpose; such
continuations  and conversions  merely  constitute a change in the interest rate
applicable to already outstanding Loans.



                                       15

         Section 2.4. Use of Proceeds. Borrower shall use all Loans to refinance
existing  indebtedness,  to  acquire  oil  and  gas  companies  and  oil and gas
properties,   to  finance  capital   expenditures,   to  refinance   Matured  LC
Obligations,  to provide  working  capital  for its  operations,  for  Permitted
Investments  and for other general  business  purposes.  Borrower  shall use all
Letters of Credit for its  general  corporate  purposes.  In no event  shall the
funds from any Loan or any Letter of Credit be used  directly or  indirectly  by
any Person for personal,  family,  household or agricultural purposes or for the
purpose, whether immediate, incidental or ultimate, of purchasing,  acquiring or
carrying  any  "margin  stock" or any  "margin  securities"  (as such  terms are
defined in  Regulation  U  promulgated  by the Board of Governors of the Federal
Reserve  System) or to extend credit to others  directly or  indirectly  for the
purpose of  purchasing  or carrying any such margin stock or margin  securities.
Borrower represents and warrants that Borrower is not engaged principally, or as
one of Borrower's important  activities,  in the business of extending credit to
others for the purpose of  purchasing  or carrying  such margin  stock or margin
securities.

         Section 2.5.  Interest Rates and Fees.

         (a) Interest Rates. Each Base Rate Loan shall bear interest on each day
outstanding  at the Adjusted  Base Rate in effect on such day.  Each  Eurodollar
Loan shall bear interest on each day during the related  Interest  Period at the
related Adjusted Eurodollar Rate in effect on such day.

         (b)  Tranche  A Loan  Commitment  Fee.  In  consideration  of  Lenders'
commitment  to enter into this  Agreement  and to advance  funds to  Borrower as
Tranche A Loans,  Borrower will pay to Agent, for pro rata  distribution to each
Lender in accordance with its Percentage Share, a commitment fee determined on a
daily  basis by  applying  the Tranche A  Commitment  Fee Rate to such  Lender's
Percentage  Share of the unused  portion of the Tranche A Borrowing Base on each
day during  the  Tranche A  Revolving  Period,  determined  for each such day by
deducting from the amount of the Tranche A Borrowing Base at the end of such day
the Tranche A Facility Usage.  Promptly at the end of each Fiscal Quarter and at
the end of the Tranche A Revolving Period,  Agent shall calculate the commitment
fee  then  due and  shall  notify  Borrower  thereof.  Borrower  shall  pay such
commitment  fee to Agent within five Business Days after  receiving such notice.
As used in this section, "Tranche A Commitment Fee Rate" means:

                  (i)  when the Debt to Capitalization Ratio in effect hereunder
         is less than 0.50 to 1.0, 0.25% per annum; or

                  (ii) when the Debt to Capitalization Ratio in effect hereunder
         is greater than or equal to 0.50 to 1.0, 0.50% per annum.

         For the purposes of this Section 2.5(b),  any increase in the Tranche A
Borrowing Base pursuant to Section 2.1(c) shall be effective as of the first day
of the  calendar  quarter in which  Borrower  elects to  increase  the Tranche A
Borrowing Base.

         (c)  Tranche  B  Loan   Commitment  Fee.  In  consideration of Lenders'
commitment  to enter into this  Agreement  and to advance  funds to  Borrower as
Tranche B Loans,  Borrower will pay to Agent, for pro rata  distribution to each
Lender in accordance with its Percentage Share, a commitment fee determined on a
daily  basis by  applying  the Tranche B  Commitment  Fee Rate to such  Lender's
Percentage  Share of the unused  portion of the Tranche B Borrowing Base on each
day during  the  Tranche B  Revolving  Period,  determined  for each such day by
deducting  from  the  amount  of the  Borrowing  Base at the end of such day the
Tranche B Facility Usage.  Promptly at the end of each Fiscal Quarter and at the
end of the Tranche B Revolving Period,  Agent shall calculate the commitment fee
then due and shall notify Borrower  thereof.  Borrower shall pay such commitment
fee to Agent within five Business Days after  receiving such notice.  As used in
this  section,  "Tranche  B  Commitment  Fee Rate"  means:  (i) when the Debt to
Capitalization  Ratio in effect  hereunder is less than 0.50 to 1.0,  0.125% per
annum;



                                       16
<PAGE>

                  (ii) when the Debt to Capitalization Ratio in effect hereunder
         is greater than or equal to 0.50 to 1.0, 0.375% per annum

         For the purposes of this Section 2.5(c),  any decrease in the Tranche B
Borrowing Base pursuant to Section 2.1(c) shall be effective as of the first day
of the  calendar  quarter in which  Borrower  elects to  increase  the Tranche A
Borrowing Base thereby reducing the Tranche B Borrowing Base.

         (d)  Facility  Fees.   Each  time  the  Aggregate   Borrowing  Base  is
redetermined  pursuant to Section 2.9 and the amount of the new  Borrowing  Base
exceeds the Aggregate  Borrowing Base previously in effect hereunder (the amount
of such  excess  is  herein  called  the  "Increased  Aggregate  Borrowing  Base
Amount"),  Borrower shall pay to Agent, for pro rata distribution to each Lender
in accordance  with its  Percentage  Share, a facility fee in an amount equal to
0.125% of the Increased  Aggregate  Borrowing Base Amount.  All  calculations of
facility fees made  pursuant to this section shall be made after the  acceptance
of the Aggregate Borrowing Base by Borrower pursuant to Section 2.10.

         (e)  Conversion  Fee.   Borrower  shall  pay  to  Agent  for  pro  rata
distribution to each Lender in accordance with its Percentage Share a conversion
fee in the amount of 0.25% of that portion of the Tranche B Borrowing Base which
is being converted into the Tranche A Borrowing Base under Section 2.1(c).

         (f) Other Fees. In addition to all other amounts due to Agent under the
Loan  Documents,  Borrower  will  pay fees to  Agent  as  described  in a letter
agreement of even date herewith between Agent and Borrower.

         (g)  Changes  in  Base  Rate  Margin,   Eurodollar  Margin,  Tranche  A
Commitment Fee Rate and Tranche B Commitment Fee Rate .

                  (i)  Initial  Debt  to  Capitalization   Ratio.  The  Debt  to
         Capitalization  Ratio in effect from the date hereof  until  changed as
         herein provided is 0.125 to 1.0.

                  (ii)  Decreases In Rates.  Any  reduction in the Adjusted Base
         Rate, the Adjusted  Eurodollar  Rate, the Tranche A Commitment Fee Rate
         or the  Tranche B  Commitment  Fee Rate (in this  section  collectively
         called  the   "Rates")  as  a  result  of  a  change  in  the  Debt  to
         Capitalization  Ratio shall be requested  by Borrower in a  certificate
         delivered  to  Agent  in  which  Borrower  certifies  as to the Debt to
         Capitalization  Ratio in effect on the date thereof.  Together with any
         such  certificate,  Borrower  shall  deliver to Agent true and  correct
         financial statements of Borrower, in form and substance satisfactory to
         Agent, supporting Borrower's calculation of such Debt to Capitalization
         Ratio.  If Agent  determines  Borrower's  calculation  is correct,  the
         reduction in the Rates shall become effective on the fifth Business Day
         following  the date on which  such  notice is given to Agent or Lenders
         otherwise  become aware of such a change in the Debt to  Capitalization
         Ratio;  provided that with respect to Committed  Eurodollar Loans, such
         decrease  shall apply only to Eurodollar  Loans  Continued or converted
         after such effective date.

                  (iii) Increases In Rates.  With respect to any increase in the
         Rates,  Borrower  must  notify  Agent of any  change  in the Rates as a
         result  of a  change  in the  Debt to  Capitalization  Ratio.  Any such
         increase in the Rates shall become  effective on the fifth Business Day
         following  the date on which  such  notice is given to Agent or Lenders
         otherwise  become aware of such a change in the Debt to  Capitalization
         Ratio;  provided that with respect to Eurodollar  Loans,  such increase
         shall apply only to Eurodollar Loans made, continued or converted after
         such effective date.

         Section 2.6. Optional Prepayments.  Borrower may, from time to time and
without premium or penalty prepay the Notes, in whole or in part, so long as the
aggregate  amounts of all partial  prepayments  of principal on the Notes equals
$250,000  or any  higher  integral  multiple  of  $50,000,  and so  long  as any
prepayment  of a Eurodollar  Loan is  accompanied  by amounts owed under Section
3.6. Each partial  prepayment of principal of the Tranche A Loans made after the
end of  the  Tranche  A  Revolving  Period  shall  be  applied  to  the  regular
installments  of  principal  due under the Notes in the  inverse  order of their
maturities.  Any principal or interest prepaid pursuant to this section shall be
in addition to, and not in lieu of, all payments  otherwise  required to be paid
under the Loan Documents at the time of such prepayment.

         Section 2.7.  Required Principal Payments.

         (a) Mandatory Prepayments.  If at any time the Tranche A Facility Usage
is in excess of the Tranche A Borrowing  Base (such excess  being herein  called
the "Tranche A Excess  Debt"),  Borrower  shall,  within ten Business Days after
Agent gives notice of such fact to Borrower,  notify Agent that Borrower will do
one of the following:

          (i) within thirty (30) calendar days,  prepay the principal of
         the  Tranche  A Loans in an  aggregate  amount  at least  equal to such
         Tranche A Excess  Debt (or,  if the  Tranche A Loans  have been paid in
         full,  pay  to LC  Issuer  LC  Collateral  as  required  under  Section
         2.15(a)), or

                  (ii) prepay the  principal of the Tranche A Loans in up to six
         monthly  installments  in an  aggregate  amount  at least  equal to the
         Tranche A Excess Debt, with each such installment equal to or in excess
         of one-sixth  of such  Tranche A Excess  Debt,  and with the first such
         installment  to be paid one month  after the giving of such  notice and
         the  subsequent  installments  to be  due  and  payable  at  one  month
         intervals  thereafter  until  such  Tranche  A  Excess  Debt  has  been
         eliminated, or

                  (iii) within thirty (30) calendar days,  convert the aggregate
         outstanding  principal  amount of the  Tranche A Notes to a term  loan,
         which shall be subject to the provisions of paragraph 2.7(c).

Borrower  shall make the  payment(s)  or  conversion  selected  by  Borrower  as
described  above.  Any  principal or interest  prepaid  pursuant to this section
shall be in addition to, and not in lieu of, all payments  otherwise required to
be paid under the Loan Documents at the time of such prepayment.

         (b) Tranche B Loan. If at any time the Tranche B Facility Usage exceeds
the Tranche B Borrowing Base then in effect (such excess is  hereinafter  called
the "Tranche B Excess Debt"),  Borrower shall take one of the following  actions
within three  Business  Days  following  receipt of notice from the Agent of the
existence of such Tranche B Excess Debt:

                  (i) Convert the Tranche B Excess Debt to principal outstanding
         under  the  Tranche  A Loan,  and  execute  and  deliver  to the  Banks
         amendments to the Loan Documents satisfactory to Lenders; or

                  (ii)  Repay  the  Tranche  B Loan in an  amount  equal  to the
Tranche B Excess Debt.

Each  prepayment  of principal  under this section shall be  accompanied  by all
interest then accrued and unpaid on the  principal so prepaid.  Any principal or
interest  prepaid  pursuant to this section  shall be in addition to, and not in
lieu of, all payments  otherwise required to be paid under the Loan Documents at
the time of such prepayment.

Failure to timely comply with this paragraph  2.7(b) shall be an immediate Event
of Default.

         (c) Regularly  Scheduled  Payments of Principal of Tranche A Note.  The
principal  of the  Tranche  A Note  shall  be due and  payable  in  twenty  (20)
quarterly  installments,  each of which  shall be  equal to the  greater  of (i)
one-twentieth  (1/20) of the aggregate unpaid principal balance of the Tranche A
Note at the end of the Tranche A Revolving Period or (ii) sixty percent (60%) of
the Net Oil and Gas Revenues during the applicable Accounting Quarter, and shall
be due and payable on the last day of each Fiscal  Quarter,  beginning March 31,
2001 and continuing  regularly  thereafter until the Tranche A Maturity Date, at
which time the unpaid  principal  balance of the Tranche A Note and all interest
accrued thereon shall be due and payable in full.

         Section 2.8.  Borrowing Base.

         (a) Initial  Aggregate  Borrowing  Base; Limitations on Borrowing Base.
The initial borrowing base under this Agreement shall be $115,000,000.

         (b) Engineering  Reports.  No later than March 1 of each year that this
Agreement is in effect,  commencing March 1, 1999, Borrower shall submit to each
Lender,  in a format and using the pricing  and cost  assumptions  and  discount
factors required by the Securities and Exchange Commission,  a report,  prepared
by a qualified  independent or in-house  engineer  acceptable to Agent,  setting
forth, as of December 31 of the immediately  preceding year, all of the revenues
(and the future volumes of production to be derived  therefrom)  attributable to
all proved Oil and Gas Properties owned by Borrower as of such date.

         Section 2.9. Subsequent  Determinations of Aggregate Borrowing Base. By
each  Evaluation  Date Borrower  shall  furnish to each Lender all  information,
reports and data which Agent has then requested  concerning  Borrower's business

and  properties  (including  their oil and gas  properties and interests and the
reserves and production relating thereto),  together with the Engineering Report
described in Section 2.8(b) and Section 6.2(d),  if then due. Within  forty-five
days  after  receiving  such  information,  reports  and  data,  or as  promptly
thereafter as practicable,  Majority  Lenders shall agree upon an amount for the
Aggregate  Borrowing  Base and Agent shall by notice to Borrower  designate such
amount as the new  Aggregate  Borrowing  Base  available to Borrower  hereunder,
which designation shall take effect  immediately on the date such notice is sent
(herein called a "Determination  Date") and shall remain in effect until but not
including  the  next  date  as  of  which  the  Aggregate   Borrowing   Base  is
redetermined.  If Borrower  does not furnish all such  information,  reports and
data by the date  specified  in the first  sentence of this  section,  Agent may
nonetheless  designate the Aggregate Borrowing Base at any amount which Majority
Lenders determine and may redesignate the Aggregate  Borrowing Base from time to
time  thereafter  until each Lender receives all such  information,  reports and
data,  whereupon Majority Lenders shall designate a new Aggregate Borrowing Base
as described above. Majority Lenders shall determine the amount of the Aggregate
Borrowing  Base  based  upon  the  loan  collateral  value  which  they in their
discretion  assign to the various oil and gas properties of Borrower at the time
in  question  and based  upon  such  other  credit  factors  (including  without
limitation the assets,  liabilities,  cash flow, hedged and unhedged exposure to
price, foreign exchange rate, and interest rate changes,  business,  properties,
prospects,  management and ownership of Borrower and its  Affiliates) as they in
their discretion deem significant.  It is expressly  understood that Lenders and
Agent have no obligation to agree upon or designate the Aggregate Borrowing Base
at any  particular  amount,  whether in relation  to the Maximum  Loan Amount or
otherwise,   and  that  Lenders'  commitments  to  advance  funds  hereunder  is
determined  by reference to the  Aggregate  Borrowing  Base from time to time in
effect, which Aggregate Borrowing Base shall be used for calculating  commitment
fees under  Section  2.5 and,  to the  extent  permitted  by Law and  regulatory
authorities,   for  the   purposes  of  capital   adequacy   determination   and
reimbursements under Section 3.2.

         Section 2.10.  Acceptance and Application of Aggregate  Borrowing Base.
Within  ten days after the Agent has given  written  notice to  Borrower  of the
Aggregate Borrowing Base offered by the Agent for a period,  Borrower shall give



                                       19
<PAGE>

Agent  written  notice  of  Borrower's  acceptance  of all or a  portion  of the
Aggregate  Borrowing  Base for  such  period.  In such  notice,  Borrower  shall
allocate a portion of the Aggregate  Borrowing  Base so accepted by the Borrower
to the Tranche A Loan (the "Tranche A Borrowing Base") and the remaining portion
to the Tranche B Loan (the "Tranche B Borrowing Base"), provided,  however, that
in no event shall (i) more than $200,000,000 of the Aggregate  Borrowing Base be
allocated to the Tranche A Loan,  (ii) more than  $50,000,000  of the  Aggregate
Borrowing  Base be allocated to the Tranche B Loan or (iii) more than the lesser
of (x) the amount of the Tranche B Commitment or (y) 50% of Aggregate  Borrowing
Base be allocated to the Tranche B Loan.  Each such Tranche A Borrowing Base and
each such Tranche B Borrowing Base shall be effective as of the date so accepted
by Borrower  until the date on which a new  Tranche A  borrowing  Base and a new
Tranche B Borrowing Base is accepted by Borrower. The initial accepted Tranche A
Borrowing Base shall be $30,000,000;  the initial  accepted  Tranche B Borrowing
Base shall be $10,000,000.

         Section 2.11.  Letters of Credit.  Subject to the terms and  conditions
hereof,  Borrower may during the Tranche A Revolving Period request LC Issuer to
issue one or more Letters of Credit,  provided that, after taking such Letter of
Credit into account:

         (a) the   Tranche  A  Facility  Usage  does not  exceed  the  Tranche A
Borrowing Base at such time; and

         (b) the  Aggregate  Facility  Usage  does  not  exceed  the  Aggregate
Borrowing Base; and

         (c) the expiration date of such Letter of Credit is prior to the end of
the Tranche A Revolving Period.

LC Issuer has no obligation or commitment to issue any such Letter of Credit. LC
Issuer  may  choose to honor any such  request  for a Letter of  Credit,  and LC
Issuer may refuse to issue any  requested  Letter of Credit for any reason which
LC  Issuer  in its  sole  discretion  deems  relevant.  The  provisions  of this
Agreement  dealing  with  Letters  of Credit  have  been  agreed to only for the
convenience  of the  parties if LC Issuer  does  ultimately  choose to issue any
Letter of Credit.

LC Issuer may choose to honor any such  request  for any other  Letter of Credit
but has no  obligation  to do so and may  refuse to issue  any  other  requested
Letter of Credit for any  reason  which LC Issuer in its sole  discretion  deems
relevant.

         Section 2.12. Requesting Letters of Credit.  Borrower must make written
application for any Letter of Credit at least five Business Days before the date
on which  Borrower  desires  for LC Issuer to issue such  Letter of  Credit.  By
making any such written application Borrower shall be deemed to have represented
and warranted that the LC Conditions  described in Section 4.2 will be met as of
the date of issuance of such Letter of Credit. Each such written application for
a Letter of Credit must be made in writing in the form and  substance of Exhibit
G, the terms and provisions of which are hereby incorporated herein by reference
(or in  such  other  form as may  mutually  be  agreed  upon  by LC  Issuer  and
Borrower).  If any provisions of any LC Application conflict with any provisions
of this Agreement, the provisions of this Agreement shall govern and control.

         Section 2.13.  Reimbursement and Participations.

         (a)  Reimbursement  by  Borrower.  Each  Matured  LC  Obligation  shall
constitute  a loan by LC  Issuer to  Borrower.  Borrower  promises  to pay to LC
Issuer,  or to LC Issuer's order, on demand,  the full amount of each Matured LC
Obligation,  together with interest thereon at the Default Rate, until repaid in
full.



                                       20
<PAGE>

         (b)  Letter of Credit  Advances.  If the  beneficiary  of any Letter of
Credit makes a draft or other demand for payment  thereunder then Lenders shall,
if all of the  conditions  precedent  to making  such Loans set forth in Section
2.1(a) and Article IV have been satisfied,  make Loans to Borrower in the amount
of such draft or demand, which Loans shall be made concurrently with LC Issuer's
payment of such draft or demand  and shall be  immediately  used by LC Issuer to
repay the amount of the resulting  Matured LC Obligation;  provided that for the
purposes of the first sentence of Section 2.1, the amount of such Loans shall be
considered,  but the amount of the Matured LC Obligation to be concurrently paid
by such Loans shall not be considered.

         (c) Participation by Lenders. LC Issuer irrevocably agrees to grant and
hereby  grants to each  Lender,  and -- to induce LC Issuer to issue  Letters of
Credit  hereunder -- each Lender  irrevocably  agrees to accept and purchase and
hereby  accepts  and  purchases  from LC  Issuer,  on the terms  and  conditions
hereinafter  stated and for such  Lender's  own  account  and risk an  undivided
interest equal to such Lender's Percentage Share of LC Issuer's  obligations and
rights  under  each  Letter of Credit  issued  hereunder  and the amount of each
Matured LC Obligation paid by LC Issuer thereunder.  Each Lender unconditionally
and  irrevocably  agrees with LC Issuer that, if a Matured LC Obligation is paid
under  any  Letter of Credit  for which LC Issuer is not  reimbursed  in full by
Borrower  in  accordance  with the terms of this  Agreement  and the  related LC
Application  (including any reimbursement by means of concurrent Loans or by the
application  of LC  Collateral),  such Lender  shall (in all  circumstances  and
without  set-off or  counterclaim)  pay to LC Issuer on demand,  in  immediately
available  funds at LC Issuer's  address for notices  hereunder,  such  Lender's
Percentage Share of such Matured LC Obligation (or any portion thereof which has
not been  reimbursed  by Borrower).  Each  Lender's  obligation to pay LC Issuer
pursuant to the terms of this  subsection is irrevocable and  unconditional.  If
any  amount  required  to be paid by any  Lender to LC Issuer  pursuant  to this
subsection is paid by such Lender to LC Issuer within three  Business Days after
the date such  payment is due,  LC Issuer  shall in  addition  to such amount be
entitled to recover from such Lender,  on demand,  interest  thereon  calculated
from such due date at the Federal Funds Rate. If any amount  required to be paid
by any  Lender  to LC Issuer  pursuant  to this  subsection  is not paid by such
Lender to LC Issuer  within three  Business  Days after the date such payment is
due, LC Issuer shall in addition to such amount be entitled to recover from such
Lender, on demand, interest thereon calculated from such due date at the Default
Rate.

         (d) Distributions to Participants. Whenever LC Issuer has in accordance
with this section  received from any Lender payment of such Lender's  Percentage
Share of any Matured LC Obligation, if LC Issuer thereafter receives any payment
of such  Matured LC  Obligation  or any  payment of  interest  thereon  (whether
directly from  Borrower or by  application  of LC  Collateral or otherwise,  and
excluding  only  interest for any period  prior to LC Issuer's  demand that such
Lender make such payment of its Percentage  Share), LC Issuer will distribute to
such  Lender  its  Percentage  Share of the  amounts so  received  by LC Issuer;
provided,  however,  that  if  any  such  payment  received  by LC  Issuer  must
thereafter  be returned by LC Issuer,  such Lender shall return to LC Issuer the
portion thereof which LC Issuer has previously distributed to it.

         Section 2.14.  Letter of Credit Fees. In  consideration  of LC Issuer's
issuance of any Letter of Credit,  Borrower agrees to pay (a) to Agent,  for the
account of all Lenders in accordance with their respective  Percentage Shares, a
letter of credit  issuance fee at a rate  determined by applying the  Eurodollar
Margin  then in effect to the face  amount of such Letter of Credit for the term
thereof, such issuance fee to be not less than $1,000 for each Letter of Credit,
and (b) to the LC Issuer for its own account, a letter of credit fronting fee at
a rate equal to one-eighth  percent (.125%) per annum of the face amount of such
letter of credit. Each such fee will be payable quarterly in arrears.

         Section 2.15.  LC Collateral.

         (a) LC Obligations in Excess of Borrowing  Base. If the  outstanding LC
Obligations  exceed the Tranche A Borrowing Base, then in addition to prepayment
of the entire  principal  balance of the Loans  pursuant to Section 2.7 Borrower
will immediately pay to LC Issuer an amount equal to such excess. LC Issuer will
hold such amount as security for the remaining LC Obligations  (all such amounts
held as  security  for LC  Obligations  being  herein  collectively  called  "LC
Collateral") until such LC Obligations  become Matured LC Obligations,  at which
time such LC Collateral may be applied to such Matured LC  Obligations.  Neither
this subsection nor the following subsection shall, however, limit or impair any
rights which LC Issuer may have under any other  document or agreement  relating
to any Letter of Credit or LC Obligation,  including any LC Application,  or any
rights  which any  Lender  Party may have to  otherwise  apply any  payments  by
Borrower and any LC Collateral under Section 3.1.



                                       21
<PAGE>

         (b)  Acceleration  of LC  Obligations.  If the  Obligations or any part
thereof become  immediately due and payable pursuant to Section 8.1 then, unless
Majority Lenders  otherwise  specifically  elect to the contrary (which election
may thereafter be retracted by Majority Lenders at any time), all LC Obligations
shall become immediately due and payable without regard to whether or not actual
drawings or payments on the Letters of Credit have occurred,  and Borrower shall
be obligated to pay to LC Issuer immediately an amount equal to the aggregate LC
Obligations  which are then  outstanding.  All  amounts so paid  shall  first be
applied to Matured LC  Obligations  and then held by LC Issuer as LC  Collateral
until such LC Obligations  become Matured LC Obligations,  at which time such LC
Collateral shall be applied to such Matured LC Obligations.

         (c) Investment of LC Collateral.  Pending application  thereof,  all LC
Collateral  shall be invested by LC Issuer in such  Investments as LC Issuer may
choose in its sole  discretion.  All  interest on (and other  proceeds  of) such
Investments  shall be reinvested or applied to Matured LC Obligations.  When all
Obligations  have been  satisfied in full,  including  all LC  Obligations,  all
Letters  of  Credit  have  expired  or been  terminated,  and all of  Borrower's
reimbursement  obligations in connection  therewith have been satisfied in full,
LC Issuer shall release any remaining LC  Collateral.  Borrower  further  agrees
that LC Issuer  shall  have all of the rights and  remedies  of a secured  party
under the  Uniform  Commercial  Code as  adopted in the State of  Colorado  with
respect  to such  security  interest  and that an Event of  Default  under  this
Agreement shall constitute a default for purposes of such security interest.

         (d) Payment of LC  Collateral.  When Borrower is required to provide LC
Collateral for any reason and fails to do so on the day when required, LC Issuer
may  without  notice  to  Borrower  provide  such  LC  Collateral   (whether  by
application  of proceeds of other  Collateral,  by transfers from other accounts
maintained with LC Issuer,  or otherwise)  using any available funds of Borrower
or any other Person also liable to make such payments.


                       ARTICLE III - Payments to Lenders

         Section 3.1. General Procedures.  Borrower will make each payment which
it owes under the Loan Documents to Agent for the account of the Lender Party to
whom such payment is owed. Each such payment must be received by Agent not later
than 11:30 a.m.,  Dallas,  Texas time, on the date such payment  becomes due and
payable,  in lawful  money of the United  States of  America,  without  set-off,
deduction or  counterclaim,  and in  immediately  available  funds.  Any payment
received  by Agent  after such time will be deemed to have been made on the next
following  Business Day. Should any such payment become due and payable on a day
other than a Business Day, the maturity of such payment shall be extended to the
next succeeding Business Day, and, in the case of a payment of principal or past
due  interest,  interest  shall accrue and be payable  thereon for the period of
such extension as provided in the Loan Document under which such payment is due.
Each  payment  under a Loan  Document  shall  be due and  payable  at the  place
provided therein and, if no specific place of payment is provided,  shall be due
and  payable at the place of payment of Agent's  Note.  When Agent  collects  or
receives money on account of the  Obligations,  Agent shall distribute all money
so collected  or  received,  and each Lender Party shall apply all such money so
distributed, as follows:



                                       22
<PAGE>

         (a) first,  for the payment of all Obligations  which are then due (and
if  such  money  is  insufficient  to pay all  such  Obligations,  first  to any
reimbursements  due  Agent  under  Section  6.9 or 10.4 and then to the  partial
payment of all other  Obligations then due in proportion to the amounts thereof,
or as Lender Parties shall otherwise agree);

         (b) then for the prepayment of amounts owing under the  Loan  Documents
(other than principal on the Notes) if so specified by Borrower;

         (c) then for  the prepayment of  principal on the  Notes, together with
accrued and unpaid interest on the principal so prepaid; and

         (d) last, for the payment or prepayment of any other Obligations.

All payments applied to principal or interest on any Note shall be applied first
to any interest  then due and payable,  then to principal  then due and payable,
and last to any prepayment of principal and interest in compliance with Sections
2.6 and 2.7. All  distributions of amounts  described in any of subsections (a),
(b),  (c) or (d) above shall be made by Agent pro rata to each Lender Party then
owed Obligations  described in such subsection in proportion to all amounts owed
to all Lender Parties which are described in such  subsection;  provided that if
any Lender then owes  payments to LC Issuer for the purchase of a  participation
under Section 2.13(c) hereof,  any amounts  otherwise  distributable  under this
section to such Lender shall be deemed to belong to LC Issuer,  to the extent of
such unpaid  payments,  and Agent  shall apply such  amounts to make such unpaid
payments rather than distribute such amounts to such Lender.

         Section 3.2.  Increased Cost and Reduced Return.

         (a) If, after the date  hereof,  the  adoption of any  applicable  Law,
rule, or regulation,  or any change in any applicable  Law, rule, or regulation,
or  any  change  in  the   interpretation  or  administration   thereof  by  any
governmental  authority,  central bank, or  comparable  agency  charged with the
interpretation or administration thereof, or compliance by any Lender Party with
any  request or  directive  (whether or not having the force of Law) of any such
governmental authority, central bank, or comparable agency:

                  (i) shall subject such Lender Party to any tax, duty, or other
         charge with respect to any Loans,  its Note, or its  obligation to make
         Loans,  or change the basis of taxation of any amounts  payable to such
         Lender  Party under this  Agreement or its Note in respect of any Loans
         or  Letters of Credit  (other  than taxes  imposed on the  overall  net
         income of such Lender  Party by the  jurisdiction  in which such Lender
         Party has its principal office;

                  (ii) shall impose,  modify,  or deem  applicable  any reserve,
         special deposit,  assessment,  or similar  requirement  (other than the
         Reserve  Requirement  utilized  in the  determination  of the  Adjusted
         Eurodollar  Rate)  relating to any extensions of credit or other assets
         of, or any deposits with or other  liabilities or commitments  of, such
         Lender Party, including the commitments of such Lender Party hereunder;
         or

                  (iii)  shall  impose  on  such  Lender  Party  or  the  London
         interbank  market any other  condition  affecting this Agreement or its
         Notes  or  any  of  such   extensions  of  credit  or   liabilities  or
         commitments;



                                       23
<PAGE>

and the result of any of the  foregoing  is to increase  the cost to such Lender
Party of making, converting into, continuing, or maintaining any Eurodollar Rate
Loans or to reduce any sum  received or  receivable  by such Lender Party within
fifteen (15) days after demand therefor,  under this Agreement or its Notes with
respect to any  Eurodollar  Rate Loans,  then Borrower  shall pay to such Lender
Party such  amount or  amounts as will  compensate  such  Lender  Party for such
increased  cost or  reduction.  If any Lender  Party  requests  compensation  by
Borrower under this Section 3.5(a), Borrower may, by notice to such Lender Party
(with a copy to Agent),  suspend the  obligation of such Lender Party to make or
continue Loans of the Type with respect to which such compensation is requested,
or to convert  Loans of such Type into Loans of any other Type,  until the event
or condition  giving rise to such request ceases to be in effect;  provided that
such  suspension  shall not affect the right of such Lender Party to receive the
compensation so requested.

         (b) If, after the date hereof, LC Issuer or any Lender Party shall have
determined  that  the  adoption  of any  applicable  Law,  rule,  or  regulation
regarding  capital  adequacy or any change therein or in the  interpretation  or
administration  thereof  by  any  governmental   authority,   central  bank,  or
comparable agency charged with the interpretation or administration  thereof, or
any request or directive  regarding  capital adequacy (whether or not having the
force of Law) of any such  governmental  authority,  central bank, or comparable
agency,  has or would  have the  effect  of  reducing  the rate of return on the
capital of such Lender Party or any corporation controlling such Lender Party as
a consequence  the  obligations of LC Issuer or such Lender Party hereunder to a
level below that which such Lender Party or such corporation could have achieved
but for such adoption,  change, request, or directive (taking into consideration
its  policies  with  respect to capital  adequacy),  then from time to time upon
demand  Borrower  shall pay to LC Issuer or such  Lender  Party such  additional
amount or amounts as will  compensate  LC Issuer or such  Lender  Party for such
reduction,  but  only  to the  extent  that  such  Lender  Party  has  not  been
compensated therefor by any increase in the Adjusted Eurodollar Rate.

         (c) LC Issuer and each Lender Party shall promptly  notify Borrower and
Agent of any event of which it has knowledge,  occurring  after the date hereof,
which will  entitle LC Issuer or such Lender Party to  compensation  pursuant to
this Section.  LC Issuer or any Lender Party  claiming  compensation  under this
Section  shall  furnish to  Borrower  and Agent a  statement  setting  forth the
additional  amount  or  amounts  to be  paid  to it  hereunder  which  shall  be
conclusive in the absence of manifest  error.  In  determining  such amount,  LC
Issuer or such Lender  Party shall act in good faith and may use any  reasonable
averaging and attribution methods.

         Section 3.3. Limitation on Types of Loans.  If on or prior to the first
day of any Interest Period for any Eurodollar Rate Loan:

         (a) Agent determines (which  determination shall be conclusive) that by
reason of circumstances  affecting the relevant market,  adequate and reasonable
means do not  exist  for  ascertaining  the  Eurodollar  Rate for such  Interest
Period; or

         (b)  Majority   Lenders   determine  (which   determination   shall  be
conclusive)  and  notify  Agent  that  the  Adjusted  Eurodollar  Rate  will not
adequately  and  fairly  reflect  the  cost to the  Lender  Parties  of  funding
Eurodollar Loans for such Interest Period;

then Agent shall give Borrower  prompt notice  thereof  specifying  the relevant
Type of Loans and the relevant amounts or periods, and so long as such condition
remains  in effect,  the Lender  Parties  shall be under no  obligation  to make
additional Loans of such Type,  continue Loans of such Type, or to convert Loans
of any other Type into Loans of such Type and Borrower shall, on the last day(s)
of the then current Interest Period(s) for the outstanding Loans of the affected
Type,  either  prepay such Loans or convert such Loans into another Type of Loan
in accordance with the terms of this Agreement.

         Section 3.4. Illegality.  Notwithstanding  any  other provision of this
Agreement,  in the event that it becomes  unlawful for any Lender Party to make,
maintain,  or fund  Eurodollar  Loans  hereunder,  then such Lender  Party shall
promptly notify Borrower  thereof and such Lender Party's  obligation to make or
continue  Eurodollar  Loans and to convert other Types of Loans into  Eurodollar
Loans shall be  suspended  until such time as such Lender  Party may again make,
maintain, and fund Eurodollar Loans (in which case the provisions of Section 1.5
shall be applicable).

         Section 3.5.  Treatment of Affected Loans.  If  the  obligation of  any
Lender  Party to make a particular  Type of Loan or to  continue,  or to convert
Loans of any other  Type into,  Loans of a  particular  Type shall be  suspended
pursuant to Sections  3.2,  3.3, or 3.4 hereof  (Loans of such Type being herein
called "Affected Loans" and such Type being herein called the "Affected  Type"),
such Lender Party's  Affected Loans shall be  automatically  converted into Base
Rate  Loans on the  last  day(s)  of the then  current  Interest  Period(s)  for
Affected Loans (or, in the case of a Conversion  required by Section 3.2 hereof,
on such earlier date as such Lender Party may specify to Borrower with a copy to
Agent) and,  unless and until such Lender Party gives  notice as provided  below
that the circumstances specified in Sections 3.2 or 3.3 hereof that gave rise to
such Conversion no longer exist:

         (a) to the extent that such Lender Party's  Affected Loans have been so
converted,  all payments and  prepayments of principal  that would  otherwise be
applied to such Lender Party's  Affected  Loans shall be applied  instead to its
Base Rate Loans; and

         (b) all Loans that would  otherwise be made or continued by such Lender
Party as Loans of the Affected  Type shall be made or continued  instead as Base
Rate Loans, and all Loans of such Lender Party that would otherwise be converted
into Loans of the Affected Type shall be converted instead into (or shall remain
as) Base Rate Loans.

If such Lender  Party gives  notice to Borrower  (with a copy to Agent) that the
circumstances  specified  in  Section  3.2 or 3.3  hereof  that gave rise to the
Conversion of such Lender Party's Affected Loans pursuant to this Section 3.5 no
longer  exist  (which  such  Lender  Party  agrees  to  do  promptly  upon  such
circumstances  ceasing to exist) at a time when Loans of the Affected  Type made
by other Lender  Parties are  outstanding,  such Lender  Party's Base Rate Loans
shall be  automatically  converted,  on the first day(s) of the next  succeeding
Interest  Period(s)  for such  outstanding  Loans of the Affected  Type,  to the
extent  necessary so that,  after giving effect  thereto,  all Loans held by the
Lender  Parties  holding Loans of the Affected Type and by such Lender Party are
held pro  rata  (as to  principal  amounts,  Types,  and  Interest  Periods)  in
accordance with their Percentage Shares of the Commitment.

         Section 3.6.  Compensation.  Upon  the  request  of any  Lender  Party,
Borrower  shall pay to such  Lender  Party  such  amount or  amounts as shall be
sufficient (in the reasonable opinion of such Lender Party) to compensate it for
any loss, cost, or expense  (including loss of anticipated  profits) incurred by
it as a result of:

         (a) any payment,  prepayment,  or Conversion of a Eurodollar  Rate Loan
for any reason  (including,  without  limitation,  the acceleration of the Loans
pursuant  to  Section  8.1) on a date  other  than the last day of the  Interest
Period for such Loan; or

         (b)  any  failure  by  Borrower  for  any  reason  (including,  without
limitation, the failure of any condition precedent specified in Article IV to be
satisfied) to borrow, convert, continue, or prepay a Eurodollar Rate Loan on the
date for such borrowing,  Conversion,  Continuation,  or prepayment specified in
the relevant notice of borrowing, prepayment,  Continuation, or Conversion under
this Agreement.

         Section 3.7.  Taxes

         (a) Any and all  payments  by  Borrower  to or for the  account  of any
Lender  Party,  Agent or LC Issuer  hereunder  or under any other Loan  Document
shall be made free and clear of and without deduction for any and all present or
future taxes, duties, levies, imposts, deductions,  charges or withholdings, and
all  liabilities  with respect  thereto,  excluding,  in the case of each Lender
Party,  Agent and LC Issuer,  taxes imposed on its income,  and franchise  taxes
imposed on it, by the jurisdiction  under the Laws of which such Lender Party or
Agent (as the case may be) is organized  or any  political  subdivision  thereof
(all such non-excluded taxes,  duties,  levies,  imposts,  deductions,  charges,
withholdings,  and liabilities  being  hereinafter  referred to as "Taxes").  If
Borrower  shall be required by Law to deduct any Taxes from or in respect of any
sum payable under this Agreement or any other Loan Document to any Lender Party,
Agent or LC Issuer,  (i) the sum payable shall be increased as necessary so that
after  making  all  required  deductions  (including  deductions  applicable  to
additional  sums payable  under this  section)  such Lender  Party,  Agent or LC
Issuer  receives an amount  equal to the sum it would have  received had no such
deductions  been made and , (ii)  Borrower  shall  make such  deductions,  (iii)
Borrower shall pay the full amount deducted to the relevant  taxation  authority
or other authority in accordance with applicable Law.

         (b) In addition,  Borrower  agrees to pay any and all present or future
stamp or documentary  taxes and any other excise or property taxes or charges or
similar  levies  which arise from any payment  made under this  Agreement or any
other Loan  Document or from the  execution or delivery  of, or  otherwise  with
respect to, this Agreement or any other Loan Document  (hereinafter  referred to
as "Other Taxes").

         (c) Borrower agrees to indemnify each Lender Party, Agent and LC Issuer
for the full amount of Taxes and Other Taxes (including, without limitation, any
Taxes or Other Taxes imposed or asserted by any  jurisdiction on amounts payable
under this  section) paid by such Lender Party or Agent (as the case may be) and
any liability (including penalties, interest, and expenses) arising therefrom or
with respect thereto.

         (d)  Without  prejudice  to the  survival  of any  other  agreement  of
Borrower hereunder, the agreements and obligations of Borrower contained in this
section shall survive the  termination of this Agreement and the payment in full
of the Notes.

         To  confirm  each  Lender's   understanding   concerning  Borrower  and

and warrants to each Lender that:

         Section 5.1. No Default.  Borrower is not in default in the performance

         Section 5.2.  Organization  and  Good  Standing.     Borrower  is  duly
organized,  validly  existing  and  in  good  standing  under  the  Laws  of its
jurisdiction  of  organization,  having  all  powers  required  to  carry on its
business  and enter  into and carry out the  transactions  contemplated  hereby.
Borrower is duly qualified,  in good standing,  and authorized to do business in
all other  jurisdictions  within the United States  wherein the character of the

makes such qualification necessary.

necessary to authorize the execution and delivery by it of the Loan Documents to
which  it is a party  and to  authorize  the  consummation  of the  transactions

of (1) any  Law,  (2)  the  organizational  documents  of  Borrower,  or (3) any
agreement,  judgment,  license,  order or permit  applicable  to or binding upon
Borrower,  (ii) result in the acceleration of any Indebtedness owed by Borrower,

Laws of general application relating to the enforcement of creditors' rights.

         Section 5.6  Initial  Financial  Statements.   Borrower has  heretofore
delivered  to each  Lender  true,  correct  and  complete  copies of the Initial

transaction contemplated hereby contains any untrue statement of a material fact
or omits to state any material fact known to Borrower (other than  industry-wide

         (k)      Any Change in Control occurs

         (l)      Any Change in Management occurs; and

         (m)      Any Material Adverse Change occurs.

Upon the  occurrence  of an Event of Default  described  in  subsection  (j)(i),
(j)(ii)  or  (j)(iii)  of this  section  with  respect to  Borrower,  all of the
Obligations  shall  thereupon be immediately  due and payable,  without  demand,
presentment,  notice of demand or of dishonor and nonpayment, protest, notice of
protest,   notice  of  intention  to   accelerate,   declaration  or  notice  of
acceleration,  or any other notice or  declaration of any kind, all of which are
hereby expressly  waived by Borrower and each Restricted  Person who at any time
ratifies or approves this Agreement. Upon any such acceleration,  any obligation
of any Lender to make any further Loans shall be permanently terminated.  During
the  continuance of any other Event of Default,  Agent at any time and from time
to time may (and upon written instructions from Majority Lenders,  Agent shall),
without notice to Borrower or any other Restricted  Person, do either or both of
the following:  (1) terminate any obligation of Lenders to make Loans hereunder,
and (2) declare any or all of the Obligations  immediately due and payable,  and
all such  Obligations  shall thereupon be immediately  due and payable,  without
demand,  presentment,  notice of demand or of dishonor and nonpayment,  protest,
notice of protest,  notice of intention to accelerate,  declaration or notice of
acceleration,  or any other notice or  declaration of any kind, all of which are
hereby expressly  waived by Borrower and each Restricted  Person who at any time
ratifies or approves this Agreement.

         Section 8.2.  Remedies.  If any  Default shall occur and be continuing,
each Lender may protect and enforce its rights  under the Loan  Documents by any
appropriate  proceedings,  including proceedings for specific performance of any
covenant  or  agreement  contained  in any Loan  Document,  and each  Lender may
enforce  the  payment of any  Obligations  due it or enforce  any other legal or
equitable  right which it may have.  All rights,  remedies and powers  conferred
upon Lender Parties under the Loan Documents shall be deemed  cumulative and not
exclusive  of any other  rights,  remedies  or powers  available  under the Loan
Documents or at Law or in equity.


                               ARTICLE IX - Agent

         Section 9.1.  Appointment, Powers, and Immunities.   Each Lender hereby
irrevocably  appoints  and  authorizes  Agent  to act as its  agent  under  this
Agreement and the other Loan  Documents  with such powers and  discretion as are
specifically  delegated  to Agent by the terms of this  Agreement  and the other
Loan  Documents,  together with such other powers as are  reasonably  incidental
thereto.  Agent (which term as used in this  sentence and in Section 9.5 and the
first  sentence of Section 9.6 hereof shall include its  Affiliates  and its own
and its Affiliates' officers,  directors,  employees, and agents): (a) shall not
have any duties or  responsibilities  except those  expressly  set forth in this
Agreement and shall not be a trustee or fiduciary for any Lender;  (b) shall not
be  responsible  to  Lenders  for any  recital,  statement,  representation,  or
warranty  (whether  written  or  oral)  made in or in  connection  with any Loan
Document or any certificate or other document referred to or provided for in, or
received by any of them under,  any Loan Document,  or for the value,  validity,
effectiveness, genuineness, enforceability, or sufficiency of any Loan Document,
or any other document  referred to or provided for therein or for any failure by
Borrower or any other Person to perform any of its obligations  thereunder;  (c)
shall not be  responsible  for or have any duty to  ascertain,  inquire into, or
verify the  performance or observance of any covenants or agreements by Borrower
or the  satisfaction of any condition or to inspect the property  (including the
books and records) of Borrower or any of its  Subsidiaries  or  Affiliates;  (d)
shall not be  required  to initiate  or conduct  any  litigation  or  collection
proceedings  under any Loan Document;  and (e) shall not be responsible  for any
action taken or omitted to be taken by it under or in  connection  with any Loan
Document,  except for its own gross negligence or willful misconduct.  Agent may
employ  agents  and  attorneys-in-fact  and  shall  not be  responsible  for the
negligence or misconduct of any such agents or attorneys-in-fact  selected by it
with reasonable care.

         Section 9.2. Reliance by Agent.  Agent shall be entitled  to rely  upon
any  certification,   notice,   instrument,   writing,  or  other  communication
(including,  without limitation,  any thereof by telephone or telecopy) believed
by it to be genuine and correct and to have been  signed,  sent or made by or on
behalf of the proper Person or Persons,  and upon advice and statements of legal
counsel (including counsel for any Restricted Person),  independent accountants,
and other experts  selected by Agent.  Agent may deem and treat the payee of any
Note as the holder  thereof  for all  purposes  hereof  unless  and until  Agent
receives and accepts an Assignment  and Acceptance  executed in accordance  with
Section  10.6  hereof.  As to any matters  not  expressly  provided  for by this
Agreement,  Agent shall not be required to exercise any  discretion  or take any
action,  but shall be  required  to act or to refrain  from acting (and shall be
fully protected in so acting or refraining from acting) upon the instructions of
the  Majority  Lenders,  and such  instructions  shall be  binding on all of the
Lenders; provided,  however, that Agent shall not be required to take any action
that  exposes  Agent  to  personal  liability  or that is  contrary  to any Loan
Document  or  applicable  Law or unless  it shall  first be  indemnified  to its
satisfaction  by Lenders  against any and all liability and expense which may be
incurred by it by reason of taking any such action.

         Section 9.3. Defaults.  Agent  shall  not be deemed  to have  knowledge
or notice of the  occurrence  of a Default or Event of Default  unless Agent has
received  written  notice from a Lender or Borrower  specifying  such Default or
Event of Default and stating  that such notice is a "Notice of  Default." In the
event that Agent  receives such a notice of the occurrence of a Default or Event
of  Default,  Agent  shall give prompt  notice  thereof to Lenders.  Agent shall
(subject to Section 9.2 hereof) take such action with respect to such Default or
Event of  Default as shall  reasonably  be  directed  by the  Majority  Lenders,
provided that, unless and until Agent shall have received such directions, Agent
may (but shall not be  obligated  to) take such  action,  or refrain from taking
such  action,  with respect to such Default or Event of Default as it shall deem
advisable in the best interest of Lenders.



                                       38
<PAGE>

         Section 9.4. Rights as Lender.  With respect  to its  Percentage  Share
and the Loans made by it, NationsBank (and any successor acting as Agent) in its
capacity as a Lender  hereunder shall have the same rights and powers  hereunder
as any other  Lender and may  exercise  the same as though it were not acting as
Agent,  and the term "Lender" or "Lenders" shall,  unless the context  otherwise
indicates,  include  Agent  in its  individual  capacity.  NationsBank  (and any
successor  acting as Agent) and its  Affiliates  may (without  having to account
therefor to any Lender) accept  deposits from,  lend money to, make  Investments
in, provide services to, and generally engage in any kind of lending,  trust, or
other  business  with  any  Restricted  Person  or any of  its  Subsidiaries  or
Affiliates as if it were not acting as Agent, and NationsBank (and any successor
acting as Agent) and its Affiliates may accept fees and other consideration from
any Restricted  Person or any of its  Subsidiaries or Affiliates for services in
connection  with this  Agreement or otherwise  without having to account for the
same to Lenders.

         Section 9.5. Indemnification.  Lenders agree to indemnify Agent (to the
extent not reimbursed  under Section  10.4(b) hereof,  but without  limiting the
obligations  of Borrower  under such section)  ratably in accordance  with their
respective Percentage Shares, for any and all liabilities,  obligations, losses,
damages,  penalties,  actions,  judgments,  suits,  costs,  expenses  (including
attorneys' fees), or disbursements of any kind and nature whatsoever that may be
imposed on, incurred by or asserted  against Agent  (including by any Lender) in
any way  relating  to or arising out of any Loan  Document  or the  transactions
contemplated  thereby  or any action  taken or  omitted by Agent  under any Loan
Document;  provided  that no Lender shall be liable for any of the  foregoing to
the extent they arise from the gross  negligence  or willful  misconduct  of the
Person to be  indemnified.  Without  limitation  of the  foregoing,  each Lender
agrees to  reimburse  Agent  promptly  upon demand for its ratable  share of any
costs or expenses payable by Borrower under Section 10.4(b),  to the extent that
Agent is not promptly  reimbursed  for such costs and expenses by Borrower.  The
agreements  contained in this section shall survive payment in full of the Loans
and all other amounts payable under this Agreement.

         Section 9.6.  Each Lender agrees that it has, independently and without
reliance  on  Agent  or any  other  Lender,  and  based  on such  documents  and
information as it has deemed  appropriate,  made its own credit  analysis of the
Borrower  and  decision  to  enter  into  this   Agreement  and  that  it  will,
independently and without reliance upon Agent or any other Lender,  and based on
such  documents  and  information  as it shall  deem  appropriate  at the  time,
continue to make its own analysis and  decisions in taking or not taking  action
under the Loan Documents.  Except for notices,  reports, and other documents and
information  expressly  required to be furnished to Lenders by Agent  hereunder,
Agent shall not have any duty or  responsibility  to provide any Lender with any
credit or other  information  concerning the affairs,  financial  condition,  or
business of any Restricted  Person or any of its Subsidiaries or Affiliates that
may come into the possession of Agent or any of its Affiliates.

         Section 9.7. Sharing of Set-Offs and Other Payments. Each Lender agrees
that if it shall,  whether  through the exercise of rights of banker's lien, set
off, or counterclaim against Borrower or otherwise,  obtain payment of a portion
of  the  aggregate  Obligations  owed  to it  which,  taking  into  account  all
distributions  made by Agent  under  Section  3.1,  causes  such  Lender to have
received  more than it would have  received had such  payment  been  received by
Agent and  distributed  pursuant to Section 3.1,  then (a) it shall be deemed to
have  simultaneously  purchased and shall be obligated to purchase  interests in
the  Obligations  as necessary to cause all Lender Parties to share all payments
as provided  for in Section 3.1,  and (b) such other  adjustments  shall be made
from time to time as shall be  equitable  to ensure  that Agent and all  Lenders
share all payments of Obligations as provided in Section 3.1; provided, however,
that nothing herein contained shall in any way affect the right of any Lender to
obtain  payment  (whether by exercise  of rights of  banker's  lien,  set-off or
counterclaim or otherwise) of indebtedness other than the Obligations.  Borrower
expressly  consents to the foregoing  arrangements and agrees that any holder of
any such  interest or other  participation  in the  Obligations,  whether or not
acquired  pursuant to the  foregoing  arrangements,  may to the  fullest  extent
permitted  by Law  exercise  any and all rights of banker's  lien,  set-off,  or
counterclaim  as fully as if such holder were a holder of the Obligations in the
amount of such interest or other participation.  If all or any part of any funds
transferred  pursuant to this section is  thereafter  recovered  from the seller
under this section which  received the same,  the purchase  provided for in this
section shall be deemed to have been  rescinded to the extent of such  recovery,
together  with  interest,  if any, if interest is required  pursuant to Tribunal
order  to be paid on  account  of the  possession  of such  funds  prior to such
recovery.



                                       39
<PAGE>

         Section 9.8. Investments.  Whenever Agent in good faith determines that
it is  uncertain  about how to  distribute  to  Lenders  any funds  which it has
received,  or whenever Agent in good faith  determines that there is any dispute
among  Lenders about how such funds should be  distributed,  Agent may choose to
defer  distribution  of the funds which are the subject of such  uncertainty  or
dispute.  If Agent in good faith  believes that the  uncertainty or dispute will
not be promptly  resolved,  or if Agent is  otherwise  required to invest  funds
pending  distribution  to  Lenders,   Agent  shall  invest  such  funds  pending
distribution;  all interest on any such Investment shall be distributed upon the
distribution  of such  Investment  and in the  same  proportion  and to the same
Persons as such  Investment.  All moneys  received by Agent for  distribution to
Lenders  (other  than to the Person who is Agent in its  separate  capacity as a
Lender)  shall be held by Agent  pending such  distribution  solely as Agent for
such Lenders, and Agent shall have no equitable title to any portion thereof.

         Section 9.9. Benefit  of  Article  IX.   The provisions of this Article
(other than the following  Section 9.11) are intended  solely for the benefit of
Lender Parties,  and no Restricted  Person shall be entitled to rely on any such
provision or assert any such provision in a claim or defense against any Lender.
Lender  Parties may waive or amend such  provisions  as they desire  without any
notice to or consent of Borrower or any Restricted Person.

         Section 9.10. Resignation.   Agent  may  resign  at any time  by giving
written notice thereof to Lenders and Borrower. Each such notice shall set forth
the date of such resignation. Upon any such resignation,  Majority Lenders shall
have the  right to  appoint a  successor  Agent,  which  shall be, so long as no
Default or Event of  Default,  Tranche A Excess  Debt or  Tranche B Excess  Debt
exists,  subject  to  Borrower's  approval,  which  shall  not  be  unreasonably
withheld. A successor must be appointed for any retiring Agent, and such Agent's
resignation shall become effective when such successor accepts such appointment.
If, within thirty days after the date of the retiring  Agent's  resignation,  no
successor Agent has been appointed and has accepted such  appointment,  then the
retiring Agent may appoint a successor  Agent,  which shall be a commercial bank
organized or licensed to conduct a banking or trust  business  under the Laws of
the United States of America or of any state thereof. Upon the acceptance of any
appointment as Agent hereunder by a successor Agent, the retiring Agent shall be
discharged  from its duties and  obligations  under this Agreement and the other
Loan Documents.  After any retiring Agent's resignation hereunder the provisions
of this  Article IX shall  continue  to inure to its  benefit as to any  actions
taken or omitted to be taken by it while it was Agent under the Loan Documents.

                            ARTICLE X - Miscellaneous

         Section 10.1.  Waivers and Amendments; Acknowledgments.

         (a) Waivers and  Amendments.  No failure or delay (whether by course of
conduct or  otherwise) by any Lender in  exercising  any right,  power or remedy
which such Lender may have under any of the Loan  Documents  shall  operate as a
waiver thereof or of any other right,  power or remedy,  nor shall any single or
partial  exercise by any Lender of any such right,  power or remedy preclude any
other or further  exercise  thereof or of any other right,  power or remedy.  No
waiver of any  provision of any Loan  Document  and no consent to any  departure
therefrom shall ever be effective unless it is in writing and signed as provided
below in this section,  and then such waiver or consent shall be effective  only
in the specific instances and for the purposes for which given and to the extent
specified in such writing.  No notice to or demand on Borrower shall in any case
of itself  entitle  Borrower to any other or further notice or demand in similar
or other  circumstances.  This  Agreement and the other Loan Documents set forth



                                       40

transactions contemplated herein and therein and supersede all prior discussions
and understandings with respect to the subject matter hereof and thereof, and no
waiver,  consent,  release,  modification  or amendment of or supplement to this
Agreement or the other Loan  Documents  shall be valid or effective  against any
party  hereto  unless the same is in writing  and signed by (i) if such party is
Borrower, by Borrower,  (ii) if such party is Agent or LC Issuer, by such party,
and  (iii) if such  party is a Lender,  by such  Lender or by Agent on behalf of
Lenders with the written consent of Majority  Lenders (which consent has already
been given as to the  termination  of the Loan  Documents as provided in Section
10.10).  Notwithstanding the foregoing or anything to the contrary herein, Agent
shall not,  without the prior  consent of each  individual  Lender,  execute and
deliver on behalf of such Lender any waiver or amendment which would:  (1) waive
any of the  conditions  specified in Article IV (provided  that Agent may in its
discretion  withdraw any request it has made under Section 4.2(f),  (2) increase
the Maximum Loan Amount of such Lender or subject such Lender to any  additional
obligations,  (3)  reduce  any fees  payable to such  Lender  hereunder,  or the
principal  of, or interest on, such Lender's  Note,  (4) postpone any date fixed
for any  payment  of any  such  fees,  principal  or  interest,  (5)  amend  the
definition herein of "Majority Lenders" or otherwise change the aggregate amount
of Percentage Shares which is required for Agent, Lenders or any of them to take
any particular action under the Loan Documents, or (6) release Borrower from its
obligation to pay such Lender's Note.

         (b)  Acknowledgments   and  Admissions.   Borrower  hereby  represents,
warrants, acknowledges and admits that (i) it has been advised by counsel in the
negotiation,  execution  and  delivery  of the Loan  Documents  to which it is a
party, (ii) it has made an independent decision to enter into this Agreement and
the  other  Loan  Documents  to  which it is a party,  without  reliance  on any
representation,  warranty,  covenant  or  undertaking  by Agent  or any  Lender,

Agreement  or in another  Loan  Document  delivered on or after the date hereof,

agreements by any Lender as to the Loan Documents except as expressly set out in
this  Agreement  or in  another  Loan  Document  delivered  on or after the date
hereof, (iv) no Lender has any fiduciary obligation toward Borrower with respect
to  any  Loan  Document  or  the  transactions  contemplated  thereby,  (v)  the
relationship  pursuant to the Loan Documents between Borrower,  on one hand, and
each  Lender,  on the other  hand,  is and shall be  solely  that of debtor  and
creditor, respectively, (vi) no partnership or joint venture exists with respect
to the Loan  Documents  between  Borrower  and any  Lender,  (vii)  Agent is not
Borrower's  Agent,  but Agent for Lenders,  (viii) should an Event of Default or
Default occur or exist,  each Lender will  determine in its sole  discretion and
for its own reasons  what  remedies  and actions it will or will not exercise or
take at that time, (ix) without  limiting any of the foregoing,  Borrower is not
relying upon any representation or covenant by any Lender, or any representative
thereof,  and no such  representation or covenant has been made, that any Lender
will,  at the time of an Event of  Default  or  Default,  or at any other  time,
waive,  negotiate,  discuss, or take or refrain from taking any action permitted
under the Loan Documents with respect to any such Event of Default or Default or
any other  provision  of the Loan  Documents,  and (x) all Lender  Parties  have
relied upon the truthfulness of the  acknowledgments in this section in deciding
to execute and deliver this Agreement and to become obligated hereunder.

         (c)  Representation  by Lenders.  Each Lender hereby represents that it
will acquire its Note for its own account in the ordinary  course of its lending
business;  however, the disposition of such Lender's property shall at all times
be and remain within its control and, in particular and without limitation, such
Lender may sell or otherwise  transfer its Note, any  participation  interest or
other interest in its Note, or any of its other rights and obligations under the
Loan Documents.

         (d) Joint  Acknowledgment.  THIS WRITTEN  AGREEMENT  AND THE OTHER LOAN
DOCUMENTS  REPRESENT  THE FINAL  AGREEMENT  BETWEEN  THE  PARTIES AND MAY NOT BE
CONTRADICTED  BY  EVIDENCE  OF  PRIOR,   CONTEMPORANEOUS,   OR  SUBSEQUENT  ORAL
AGREEMENTS OF THE PARTIES.

         THERE ARE NO UNWRITTEN ORAL AGREEMENTS BETWEEN THE PARTIES.



                                       41
<PAGE>

         Section 10.2.  Survival  of  Agreements;  Cumulative  Nature.   All  of
Borrower's various representations,  warranties, covenants and agreements in the
Loan  Documents  shall survive the execution and delivery of this  Agreement and
the other Loan Documents and the performance  hereof and thereof,  including the
making or granting of the Loans and the delivery of the Notes and the other Loan
Documents,  and shall further  survive until all of the  Obligations are paid in
full to each  Lender and all of Lender  Parties'  obligations  to  Borrower  are
terminated.  All statements and agreements contained in any certificate or other
instrument  delivered by Borrower to any Lender under any Loan Document shall be
deemed representations and warranties by Borrower or agreements and covenants of
Borrower under this Agreement. The representations, warranties, indemnities, and
covenants  made by  Restricted  Persons in the Loan  Documents,  and the rights,
powers,  and  privileges  granted to Lender Parties in the Loan  Documents,  are
cumulative,  and, except for expressly  specified waivers and consents,  no Loan
Document shall be construed in the context of another to diminish,  nullify,  or
otherwise reduce the benefit to any Lender of any such representation, warranty,
indemnity,  covenant,  right,  power or  privilege.  In  particular  and without
limitation,  no  exception  set out in  this  Agreement  to any  representation,
warranty,  indemnity,  or covenant  herein  contained shall apply to any similar
representation,  warranty,  indemnity,  or covenant  contained in any other Loan
Document, and each such similar representation, warranty, indemnity, or covenant
shall be subject only to those exceptions which are expressly made applicable to
it by the terms of the various Loan Documents.

         Section 10.3. Notices.  All notices,  requests,  consents,  demands and
other  communications  required or permitted under any Loan Document shall be in
writing,  unless otherwise specifically provided in such Loan Document (provided
that Agent may give telephonic  notices to the other Lender Parties),  and shall
be deemed sufficiently given or furnished if delivered by personal delivery,  by
facsimile or telex, by delivery service with proof of delivery, or by registered
or certified  United States mail,  postage  prepaid,  to Borrower and Restricted
Persons at the address of Borrower  specified on the signature  pages hereto and
to each Lender at its address  specified on the signature  pages hereto  (unless
changed  by similar  notice in  writing  given by the  particular  Person  whose
address is to be changed).  Any such notice or communication  shall be deemed to
have been given (a) in the case of personal delivery or delivery  service,  upon
receipt, (b) in the case of facsimile or telex, upon receipt, or (c) in the case
of registered or certified  United States mail,  three days after deposit in the
mail; provided,  however,  that no Borrowing Notice shall become effective until
actually received by Agent.

         Section 10.4.  Payment of Expenses; Indemnity.

         (a) Payment of Expenses.  Whether or not the transactions  contemplated
by this  Agreement  are  consummated,  Borrower will promptly (and in any event,
within 30 days after any  invoice or other  statement  or notice)  pay:  (i) all
transfer,  stamp, mortgage,  documentary or other similar taxes,  assessments or
charges  levied by any  governmental  or  revenue  authority  in respect of this
Agreement or any of the other Loan Documents or any other  document  referred to
herein or therein,  (ii) all  reasonable  costs and  expenses  incurred by or on
behalf  of  Agent  (including  attorneys'  fees)  in  connection  with  (1)  the
negotiation,  preparation, execution and delivery of the Loan Documents, and any
and all consents,  waivers or other documents or instruments  relating  thereto,
(2)  monitoring or confirming  (or  preparation  or  negotiation of any document
related to) Borrower's  compliance with any covenants or conditions contained in
this  Agreement  or in any Loan  Document,  and (iii) all  reasonable  costs and
expenses  incurred  by or on behalf of any Lender  Party  (including  attorneys'
fees,  consultants'  fees and accounting fees) in connection with the defense or
enforcement of any of the Loan Documents (including this section) or the defense
of any Lender Party's exercise of its rights thereunder.



                                       42
<PAGE>

         (b) Indemnity.  Borrower  agrees to indemnify  each Lender Party,  upon
demand, from and against any and all liabilities,  obligations,  claims, losses,
damages,  penalties,  fines,  actions,  judgments,  suits,  settlements,  costs,
expenses or disbursements (including reasonable fees of attorneys,  accountants,
experts  and  advisors)  of any  kind or  nature  whatsoever  (in  this  section
collectively called "liabilities and costs") which to any extent (in whole or in
part) may be imposed on,  incurred  by, or asserted  against  such Lender  Party
growing out of,  resulting from or in any other way  associated  with any of the
Loan Documents and the  transactions  and events  (including the  enforcement or
defense  thereof)  at any time  associated  therewith  or  contemplated  therein
(including any violation or  noncompliance  with any  Environmental  Laws by any
Restricted  Person or any liabilities or duties of any Restricted  Person or any
Lender Party with respect to Hazardous  Materials  found in or released into the
environment),  provided  only that no Lender Party shall be entitled  under this
section to receive  indemnification for that portion, if any, of any liabilities
and costs which is proximately  caused by its own individual gross negligence or
willful misconduct,  as determined in a final judgment. If any Person (including
Borrower or any of its Affiliates) ever alleges such gross negligence or willful
misconduct by any Lender Party, the indemnification provided for in this section
shall  nonetheless  be  paid  upon  demand,   subject  to  later  adjustment  or
reimbursement,  until such time as a court of  competent  jurisdiction  enters a
final  judgment as to the extent and effect of the alleged  gross  negligence or
willful misconduct.  As used in this section the term "Lender Party" shall refer
not  only to the  Persons  designated  as such in  Section  1.1 but also to each
director,  officer, agent, attorney,  employee,  representative and Affiliate of
such Persons.

         Section 10.5. Joint and  Several  Liability; Parties in Interest.   All
grants,  covenants and agreements contained in the Loan Documents shall bind and
inure to the benefit of the parties thereto and their respective  successors and
assigns; provided,  however, that Borrower may not may assign or transfer any of
its rights or delegate any of its duties or obligations  under any Loan Document
without  the  prior  consent  of  Majority  Lenders.  Neither  Borrower  nor any
Affiliates of Borrower shall directly or indirectly purchase or otherwise retire
any  Obligations  owed to any Lender nor will any Lender  accept any offer to do
so,  unless each Lender shall have  received  substantially  the same offer with
respect to the same Percentage  Share of the Obligations owed to it. If Borrower
or any Affiliate of Borrower at any time purchases some but less than all of the
Obligations owed to all Lender Parties,  such purchaser shall not be entitled to
any rights of any Lender under the Loan  Documents  unless and until Borrower or
its Affiliates have purchased all of the Obligations.

         Section 10.6.  Assignments and Participations

         (a) Each Lender may assign to one or more Eligible Transferees all or a
portion of its rights and obligations under this Agreement  (including,  without
limitation,  all or a portion of its Loans, its Note, and its Percentage Shares;
provided, however, that

                  (i)   each such assignment shall be to an Eligible Transferee;

                  (ii)  except in the case of an assignment to another Lender or
         an assignment of all of a Lender's  rights and  obligations  under this
         Agreement,  any such partial  assignment shall be in an amount at least
         equal to  $20,000,000  or an integral  multiple of $5,000,000 in excess
         thereof;

                  (iii) each such assignment by a Lender shall be of a constant,
         and not varying,  percentage of all of its rights and obligations under
         the Loan Documents; and

                  (iv)  the parties to such assignment shall execute and deliver
         to Agent for its acceptance an Assignment and Acceptance in the form of
         Exhibit F hereto, together with any Note subject to such assignment and
         a processing fee of $3,500.

Upon execution,  delivery, and acceptance of such Assignment and Acceptance, the
assignee  thereunder  shall  be a  party  hereto  and,  to the  extent  of  such
assignment, have the obligations, rights, and benefits of a Lender hereunder and
the assigning  Lender shall,  to the extent of such  assignment,  relinquish its
rights and be  released  from its  obligations  under this  Agreement.  Upon the
consummation of any assignment pursuant to this section, the assignor, Agent and
Borrower shall make appropriate arrangements so that, if required, new Notes are
issued to the assignor  and the  assignee.  If the assignee is not  incorporated
under the Laws of the  United  States of America  or a state  thereof,  it shall
deliver to Borrower and Agent  certification  as to exemption  from deduction or
withholding of Taxes.

         (b) Agent shall  maintain at its address  referred to in Section 10.3 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 Lenders and their
Percentage  Shares of, and  principal  amount of the Loans owing to, each Lender
from  time to time  (the  "Register").  The  entries  in the  Register  shall be
conclusive and binding for all purposes,  absent manifest  error,  and Borrower,
Agent and Lenders may treat each Person  whose name is recorded in the  Register
as a Lender hereunder for all purposes of this Agreement.  The Register shall be
available for  inspection by Borrower or any Lender at any  reasonable  time and
from time to time upon reasonable prior notice.

         (c) Upon its receipt of an Assignment  and  Acceptance  executed by the
parties  thereto,  together with any Note subject to such assignment and payment
of the processing  fee, Agent shall,  if such Assignment and Acceptance has been
completed and is in substantially the form of Exhibit F hereto,  (i) accept such
Assignment and Acceptance,  (ii) record the information contained therein in the
Register and (iii) give prompt notice thereof to the parties thereto.

         (d) Each Lender may sell  participations  to one or more Persons in all
or a portion of its  rights and  obligations  under  this  Agreement;  provided,
however,  that (i) such Lender's  obligations  under this Agreement shall remain
unchanged, (ii) such Lender shall remain solely responsible to the other parties
hereto for the performance of such  obligations,  (iii) the participant shall be
entitled to the benefit of the yield protection  provisions contained in Article
III and the right of offset  contained in Section 6.14,  and (iv) Borrower shall
continue to deal solely and directly  with such Lender in  connection  with such
Lender's  rights and  obligations  under this  Agreement,  and such Lender shall
retain the sole right to enforce the  obligations  of  Borrower  relating to its
Loans and its Note and to approve any amendment,  modification, or waiver of any
provision of this Agreement  (other than amendments,  modifications,  or waivers
decreasing  the amount of principal of or the rate at which  interest is payable
on such Loans or Note,  extending any scheduled  principal  payment date or date
fixed for the  payment of  interest  on such  Loans or Note,  or  extending  its
Tranche A Commitment or Tranche B Commitment).

         (e)  Notwithstanding  any other  provision set forth in this Agreement,
any Lender may at any time assign and pledge all or any portion of its Loans and
its  Note  to any  Federal  Reserve  Bank as  collateral  security  pursuant  to
Regulation A and any Operating  Circular issued by such Federal Reserve Bank. No
such  assignment  shall  release  the  assigning  Lender  from  its  obligations
hereunder.

         (f) Any Lender may furnish any information  concerning  Borrower or any
of its  Subsidiaries  in the  possession  of such  Lender  from  time to time to
assignees and participants  (including  prospective assignees and participants),
subject, however, to the provisions of Section 10.7 hereof.

         Section 10.7.  Confidentiality.   Each  Lender  Party  agrees  to  keep
confidential  any  information  furnished  or made  available  to it by Borrower
pursuant to this  Agreement that is marked  confidential;  provided that nothing
herein shall prevent any Lender Party from  disclosing  such  information (a) to
any other Lender Party or any  Affiliate  of any Lender  Party,  or any officer,
director,  employee,  agent,  or advisor of any Lender Party or Affiliate of any
Lender  Party,  (b)  to  any  other  Person  if  reasonably  incidental  to  the
administration  of the credit facility  provided herein,  (c) as required by any
Law,  rule,  or  regulation,  (d) upon the order of any court or  administrative
agency,  (e) upon the request or demand of any  regulatory  agency or authority,
(f) that is or becomes  available to the public or that is or becomes  available
to any Lender Party other than as a result of a  disclosure  by any Lender Party
prohibited by this  Agreement,  (g) in connection  with any  litigation to which
such Lender  Party or any of its  Affiliates  may be a party,  (h) to the extent
necessary in connection  with the exercise of any remedy under this Agreement or
any other Loan Document, and (i) subject to provisions  substantially similar to
those  contained  in this  section,  to any actual or  proposed  participant  or
assignee.

         Section 10.8. Governing  Law;  Submission to  Process.   EXCEPT  TO THE
EXTENT  THAT THE LAW OF  ANOTHER  JURISDICTION  IS  EXPRESSLY  ELECTED IN A LOAN
DOCUMENT,  THE LOAN DOCUMENTS  SHALL BE DEEMED  CONTRACTS AND  INSTRUMENTS  MADE
UNDER THE LAWS OF THE STATE OF COLORADO AND SHALL BE  CONSTRUED  AND ENFORCED IN
ACCORDANCE  WITH AND  GOVERNED BY THE LAWS OF THE STATE OF COLORADO AND THE LAWS
OF THE UNITED  STATES OF AMERICA,  WITHOUT  REGARD TO PRINCIPLES OF CONFLICTS OF
LAW.

         Section 10.9. Limitation on Interest. Lender Parties,  Borrower and any
other parties to the Loan Documents intend to contract in strict compliance with
applicable  usury Law from time to time in effect.  In furtherance  thereof such
Persons  stipulate and agree that none of the terms and provisions  contained in
the Loan Documents  shall ever be construed to create a contract to pay, for the
use, forbearance or detention of money, interest in excess of the maximum amount
of  interest  permitted  to be  charged by  applicable  Law from time to time in
effect.  Neither Borrower nor any present or future  guarantors,  endorsers,  or
other Persons hereafter becoming liable for payment of any Obligation shall ever
be liable  for  unearned  interest  thereon  or shall  ever be  required  to pay
interest  thereon in excess of the maximum  amount that may be lawfully  charged
under  applicable  Law from time to time in effect,  and the  provisions of this
section shall control over all other  provisions of the Loan Documents which may
be in conflict or apparent conflict  herewith.  Lender Parties expressly disavow
any  intention  to charge or  collect  excessive  unearned  interest  or finance
charges in the event the maturity of any Obligation is  accelerated.  If (a) the
maturity of any Obligation is accelerated for any reason,  (b) any Obligation is
prepaid and as a result any amounts held to constitute  interest are  determined
to be in excess of the legal  maximum,  or (c) any Lender or any other holder of
any  or  all of  the  Obligations  shall  otherwise  collect  moneys  which  are
determined to constitute interest which would otherwise increase the interest on
any or all of the  Obligations  to an amount in excess of that  permitted  to be
charged by applicable Law then in effect, then all sums determined to constitute
interest  in excess of such legal  limit  shall,  without  penalty,  be promptly
applied to reduce the then outstanding  principal of the related Obligations or,
at such Lender's or holder's option,  promptly returned to Borrower or the other
payor  thereof  upon  such  determination.  In  determining  whether  or not the
interest paid or payable, under any specific  circumstance,  exceeds the maximum
amount  permitted under  applicable  Law, Lender Parties and Restricted  Persons
(and any other payors  thereof)  shall to the greatest  extent  permitted  under
applicable Law, (i) characterize any non-principal payment as an expense, fee or
premium  rather than as interest,  (ii) exclude  voluntary  prepayments  and the
effects thereof,  and (iii) amortize,  prorate,  allocate,  and spread the total
amount of interest  throughout the entire  contemplated  term of the instruments
evidencing the Obligations in accordance with the amounts  outstanding from time
to time  thereunder  and the maximum legal rate of interest from time to time in
effect under  applicable  Law in order to lawfully  charge the maximum amount of
interest permitted under applicable Law.

         Section 10.10. Termination; Limited Survival.  In its sole and absolute
discretion  Borrower  may at any time that no  Obligations  are owing elect in a
written notice  delivered to Agent to terminate this Agreement.  Upon receipt by
Agent of such a notice,  if no Obligations are then owing this Agreement and all
other Loan  Documents  shall  thereupon be  terminated  and the parties  thereto
released  from  all  prospective  obligations  thereunder.  Notwithstanding  the
foregoing or anything herein to the contrary,  any waivers or admissions made by
any Restricted  Person in any Loan Document,  any Obligations under Sections 3.2
through  3.6,  and any  obligations  which any Person may have to  indemnify  or
compensate  any Lender shall survive any  termination  of this  Agreement or any
other Loan Document. At the request and expense of Borrower, Agent shall prepare
and execute all necessary  instruments to reflect and effect such termination of
the Loan Documents.  Agent is hereby  authorized to execute all such instruments
on behalf of all  Lenders,  without  the  joinder  of or  further  action by any
Lender.

         Section 10.11. Severability.   If any  term  or provision  of any  Loan
Document shall be determined to be illegal or unenforceable  all other terms and
provisions of the Loan Documents shall  nevertheless  remain effective and shall
be enforced to the fullest extent permitted by applicable Law.

         Section 10.12. Counterparts.  This Agreement may be separately executed
in any  number of  counterparts  and by  different  parties  hereto in  separate
counterparts,  each of which when so executed  shall be deemed to constitute one
and the same Agreement.

         Section 10.13. Waiver of Jury Trial, Punitive Damages, etc.    BORROWER
AND EACH LENDER HEREBY KNOWINGLY,  VOLUNTARILY,  INTENTIONALLY,  AND IRREVOCABLY
(A) WAIVES,  TO THE MAXIMUM  EXTENT NOT PROHIBITED BY LAW, ANY RIGHT IT MAY HAVE
TO A TRIAL BY JURY IN RESPECT OF ANY  LITIGATION  BASED  HEREON,  OR DIRECTLY OR
INDIRECTLY  AT ANY TIME  ARISING OUT OF,  UNDER OR IN  CONNECTION  WITH THE LOAN
DOCUMENTS  OR ANY  TRANSACTION  CONTEMPLATED  THEREBY OR  ASSOCIATED  THEREWITH,
BEFORE OR AFTER  MATURITY;  (b) WAIVES,  TO THE MAXIMUM EXTENT NOT PROHIBITED BY
LAW,  ANY  RIGHT  IT MAY HAVE TO CLAIM OR  RECOVER  IN ANY SUCH  LITIGATION  ANY
"SPECIAL DAMAGES",  AS DEFINED BELOW, (c) CERTIFIES THAT NO PARTY HERETO NOR ANY
REPRESENTATIVE  OR  AGENT OR  COUNSEL  FOR ANY  PARTY  HERETO  HAS  REPRESENTED,
EXPRESSLY  OR  OTHERWISE,  OR IMPLIED THAT SUCH PARTY WOULD NOT, IN THE EVENT OF
LITIGATION,  SEEK TO ENFORCE THE FOREGOING WAIVERS, AND (d) ACKNOWLEDGES THAT IT
HAS BEEN INDUCED TO ENTER INTO THIS AGREEMENT,  THE OTHER LOAN DOCUMENTS AND THE
TRANSACTIONS  CONTEMPLATED HEREBY AND THEREBY BY, AMONG OTHER THINGS, THE MUTUAL
WAIVERS AND CERTIFICATIONS  CONTAINED IN THIS SECTION.  AS USED IN THIS SECTION,
"SPECIAL DAMAGES" INCLUDES ALL SPECIAL,  CONSEQUENTIAL,  EXEMPLARY,  OR PUNITIVE
DAMAGES  (REGARDLESS  OF HOW NAMED),  BUT DOES NOT INCLUDE ANY PAYMENTS OR FUNDS
WHICH ANY PARTY  HERETO HAS  EXPRESSLY  PROMISED  TO PAY OR DELIVER TO ANY OTHER
PARTY HERETO.

         Section 10.14. Restatement.  This Agreement amends and  restates in its
entirety that certain  Amended and Restated Loan Agreement  dated as of April 1,
1996 between Borrower and NationsBank of Texas,  N.A., as Agent, and the lenders
named therein and the  promissory  notes issued  pursuant to such agreement (the
"Prior  Documents").  The  parties  hereto  hereby  agree  that  the  terms  and
conditions  of this  Agreement  and the Loan  Documents  executed  of even  date
herewith replace and supersede in their entirety all of the Prior Documents, and
from the effective date hereof the covenants,  obligations  and rights among the
parties hereto shall be governed  exclusively by the terms of this Agreement and
the Loan Documents  executed pursuant to this Agreement.  All security documents
which  secure  Borrower's  Obligations  under  the  Prior  Documents  which  are
currently in Agent's possession shall be returned to Borrower.

         IN WITNESS  WHEREOF,  this  Agreement  is executed as of the date first
