ITEM 1.     FINANCIAL STATEMENTS


                    REVIEW REPORT OF INDEPENDENT ACCOUNTANTS


To the Board of Directors and Stockholders
of ENSCO International Incorporated



We  have  reviewed  the  accompanying   consolidated   balance  sheet  of  ENSCO
International  Incorporated  and its  subsidiaries  as of June 30,  1998 and the
related  consolidated  statements  of income and of cash flows for the three and
six month periods ended June 30, 1998 and 1997.  This  financial  information is
the responsibility of the Company's management.


We conducted our review in accordance with standards established by the American
Institute  of  Certified  Public  Accountants.  A review  of  interim  financial
information consists principally of applying analytical  procedures to financial
data and making  inquiries of persons  responsible  for financial and accounting
matters. It is substantially less in scope than an audit conducted in accordance
with  generally  accepted  auditing  standards,  the  objective  of which is the
expression of an opinion  regarding the financial  statements  taken as a whole.
Accordingly, we do not express such an opinion.

Based on our review, we are not aware of any material  modifications that should
be made to the  accompanying  financial  information  for it to be in conformity
with generally accepted accounting principles.


We previously audited in accordance with generally accepted auditing  standards,
the  consolidated  balance  sheet  as of  December  31,  1997,  and the  related
consolidated statements of income and of cash flows for the year then ended (not
presented  herein),  and in our report  dated  January 28, 1998 we  expressed an
unqualified opinion on those consolidated financial statements.  In our opinion,
the  information  set  forth  in the  accompanying  consolidated  balance  sheet
information  as of December 31, 1997, is fairly stated in all material  respects
in relation to the consolidated balance sheet from which it has been derived.

                ENSCO INTERNATIONAL INCORPORATED AND SUBSIDIARIES
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                   (Unaudited)


Note 1 - Unaudited Financial Statements

The  accompanying  consolidated  financial  statements  of  ENSCO  International
Incorporated  (the  "Company")  have been prepared in accordance  with generally
accepted  accounting  principles,  pursuant to the rules and  regulations of the
Securities and Exchange Commission included in the instructions to Form 10-Q and
Article 10 of  Regulation  S-X. The  financial  information  included  herein is
unaudited  but,  in  the  opinion  of  management,   includes  all   adjustments
(consisting  of normal  recurring  adjustments)  which are  necessary for a fair
presentation of the financial position, results of operations and cash flows for
the interim periods presented.

The  financial  data for the three and six month  periods  ended  June 30,  1998
included    herein   have   been    subjected    to   a   limited    review   by
PricewaterhouseCoopers  LLP,  the  registrant's  independent  accountants.   The
accompanying review report of independent accountants is not a report within the
meaning of Sections 7 and 11 of the Securities  Act of 1933 and the  independent
accountant's liability under Section 11 does not extend to it.

Results of  operations  for the three and six month  periods ended June 30, 1998
are not  necessarily  indicative  of the  results  of  operations  that  will be
realized for the year ending  December 31, 1998.  It is  recommended  that these
financial  statements be read in  conjunction  with the  Company's  consolidated
financial  statements  and notes  thereto for the year ended  December  31, 1997
included  in  the  Company's  Annual  Report  to  the  Securities  and  Exchange
Commission on Form 10-K.

Note 2 - Change in Depreciable Lives

During the  latter  part of 1997,  the  Company  performed  an  engineering  and
economic  study of the  Company's  asset base.  As a result of this  study,  the
Company,  effective  January  1, 1998,  extended  the  depreciable  lives of its
drilling rigs and marine vessels by an average of five to six years. The Company
believes  that this  change  provides  a better  matching  of the  revenues  and
expenses of the Company's assets over their anticipated useful lives. The effect
of this change on the Company's  financial  results for the three and six months
ended June 30, 1998 was to reduce  depreciation  expense by approximately  $10.0
million or $.07 per basic and diluted  share and $20.0 million or $.14 per basic
and diluted share, respectively.

Note 3 - Comprehensive Income

Effective January 1, 1998, the Company adopted Statement of Financial Accounting
Standards  No.  130,  "Reporting  Comprehensive  Income."  The  adoption of this
Statement had no effect on the Company's financial statements.

Note 4 - Earnings Per Share

For the  three and six  months  ended  June 30,  1998 and  1997,  there  were no
adjustments to net income for purposes of calculating basic and diluted earnings
per share.  The following is a  reconciliation  of the weighted  average  common
shares used in the basic and diluted  earnings  per share  computations  for the
three and six months ended June 30, 1998 and 1997 (in millions).

Note 6 - Stock Buyback Program

In May 1998, the Company's Board of Directors authorized the repurchase of up to
five  million  shares of the  Company's  Common  Stock as a means to offset  the
dilutive  effect of shares issued under various  benefit plans and to capitalize
on the attractive  valuation of the Company's common stock. As of June 30, 1998,
the  Company had  repurchased  386,500  shares of its common  stock at a cost of
approximately $7.7 million.

Note 7 - Revolving Credit Agreement

In May 1998, the Company entered into a $185 million unsecured  revolving credit
agreement  (the  "Credit  Agreement")  with a  syndicate  of banks.  Interest on
amounts  borrowed  under the  Credit  Agreement  will be based on LIBOR  plus an
applicable margin rate (currently .4%) depending on the Company's credit rating.
The Company also pays a commitment fee (currently .15% per annum) on the undrawn
portion of the  available  credit  line,  which is also  based on the  Company's
credit rating.  The Company is required to maintain certain financial  covenants
under the Credit  Agreement  which include the Company meeting a specified level
of interest coverage,  assets to indebtedness,  leverage ratio, and tangible net
worth.  As of June  30,  1998,  the  Company  had  $185  million  available  for
borrowings under the Credit Agreement. The Credit Agreement matures in May 2003.

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

BUSINESS ENVIRONMENT

ENSCO International  Incorporated is one of the leading international  providers
of offshore drilling services and marine transportation  services to the oil and
gas industry.  The Company's  operations are conducted in the geographic regions
of North America, Europe, Asia Pacific and South America.

Demand  for the  Company's  services  is  significantly  affected  by  worldwide
expenditures  for oil and gas  drilling.  Expenditures  for oil and gas drilling
activity fluctuate based upon many factors including world economic  conditions,
the legislative  environment in the U.S. and other major  countries,  production
levels  and other  activities  of OPEC and other oil and gas  producers  and the
impact  that these and other  events have on the  current  and  expected  future
pricing of oil and natural gas.

During  the second  quarter of 1998,  demand  for  offshore  drilling  equipment
declined as oil prices  continued to deteriorate from price levels at the end of
1997 and at the end of the first quarter of 1998.  Oil prices have recently been
at the lowest  levels  experienced  during the last twelve  years due to,  among
other  things,  concerns  about an excess supply of oil in the world markets and
reduced growth in worldwide demand due to the impact of the economic slowdown in
Southeast  Asia. In an attempt to prevent further  deterioration  in oil prices,
members of OPEC and some other oil and gas producers  recently  agreed to reduce
their current oil  production  levels.  However,  there can be no assurance that
these agreements will reduce oil production  levels or if or when these measures
will  increase oil prices and return them to higher  levels that have  prevailed
over much of the last decade. As oil prices have declined,  companies  exploring
for oil and natural gas have deferred some of their  drilling  programs  thereby
reducing demand for drilling  equipment and marine  transportation  services and
resulting in reductions in day rates and utilization.  This erosion in day rates
and utilization is beginning to impact the Company's  financial  results and the
Company  currently expects that its earnings for the second half of 1998 will be
significantly  lower than the results for the first half of 1998.  See  "Outlook
and  Forward-Looking  Statements" for further  information about how the current
business  environment  is  expected  to impact the  Company's  future  financial
results.

RESULTS OF OPERATIONS

Although the Company's day rates and  utilization  are declining  from peak 1998
levels,  the Company's  results for the second quarter and six months ended June
30, 1998 showed  significant  improvement over the prior year periods.  Compared
with the second quarter of 1997,  revenues  increased by 20% to $234.0  million,
operating  income increased by 42% to $126.1 million and net income increased by
54% to $80.6 million. For the six months ended June 30, 1998, revenues increased
by 35% to $480.4 million,  operating  income  increased by 74% to $265.4 million
and net income  increased by 90% to $167.8 million.  These improved  results are
due  primarily  to  increased  revenues  from higher  average  day rates,  lower
depreciation  resulting  from a  change  in the  estimated  useful  lives of the

<PAGE>

Company's  drilling  rigs and marine  vessels  and a lower  effective  tax rate,
offset in part by higher operating expenses.

The following analysis  highlights the Company's operating results for the three
and six months ended June 30, 1998 and 1997 (in millions):

                                           ====      ====


         (1) Includes  one  jackup  rig that  was  previously  49%  owned by the
             Company.  The remaining 51% interest was acquired by the Company in
             May 1997.

         (2) Seven are located in the Gulf of Mexico and one, which is not owned
             but operated under a management contract,  is located off the coast
             of China.

Revenues for the Company's  contract drilling segment increased by 22% to $211.2
million  in the second  quarter of 1998,  compared  with  $172.5  million in the
second  quarter of 1997.  This  increase in revenues is  primarily  due to a 27%
improvement  in average day rates for the Company's  drilling  rigs. For the six
months ended June 30, 1998, revenues for the contract drilling segment increased
by 38% to $432.0  million,  compared with $313.3  million for the same period in
1997. This increase in revenues is primarily due to a 38% improvement in average
day rates and an increase in  utilization to 92% in the current year period from
89% in the prior year period.

The  operating  margin as a percentage  of revenues  for the  contract  drilling
segment increased to 65% in the second quarter of 1998, compared with 60% in the
second quarter of 1997. For the six months ended June 30, 1998, operating margin
as a percentage  of revenues  increased to 66%,  compared  with 58% in the prior
year  period.  The increase in  operating  margin is due to increased  revenues,
offset in part by increased  operating expenses resulting  primarily from higher
wages,  benefits and training  costs for  offshore  rig workers,  and  increased
oilfield equipment and materials costs. As demand for offshore drilling services
has  increased,  so has the demand for  qualified  personnel  and  equipment and
materials,  which has resulted in cost  increases for the Company over the prior
year periods.

   North America Jackup Rigs

For the second quarter of 1998,  revenues for the Company's North America jackup
rigs  increased by $12.9  million or 15% and the operating  margin  increased by
$10.6  million or 19% from the prior year  quarter.  The increase in revenues is
primarily  due to a 22%  improvement  in average day rates,  offset in part by a
decrease in utilization to 93% in the current year quarter from 98% in the prior
year quarter.  The decrease in utilization is due to additional downtime for rig
modifications  and  repairs,  scheduled  drydockings  and idle  time.  Operating
expenses  increased  by $2.3  million  or 8% from  the  prior  year  period  due
primarily to cost increases for operating supplies, repairs and replacements and
wages and benefits.



<PAGE>



For the six months ended June 30, 1998, revenues for the Company's North America
Jackup rigs increased by $55.1 million or 36% and the operating margin increased
by $46.2  million or 47% from the prior year period.  The increase in revenue is
primarily  due to a 35%  improvement  in day  rates  and a  slight  increase  in
utilization.  Operating expenses increased by $8.8 million or 16% from the prior
year period  primarily from cost increases for operating  supplies,  repairs and
replacements and wages and benefits.

   Europe Jackup Rigs

Second quarter  revenues for the Europe jackup rigs  increased  $20.4 million or
52% and the  operating  margin  increased by $18.5 million or 72% from the prior
year quarter.  The increase in revenues is primarily due to a 43% improvement in
average day rates with utilization  remaining constant at 100% for both periods.
Also, the acquisition of the ENSCO 100 in December 1997 contributed $3.6 million
in revenues  and $3.3  million in  operating  margin to the 1998 second  quarter
results. Operating expenses increased by $1.9 million or 14% from the prior year
quarter  primarily  from cost  increases  for  operating  supplies,  repairs and
replacements and wages and benefits.

For the six months  ended June 30,  1998,  revenues  for the Europe  jackup rigs
increased by $45.9  million or 64% and the operating  margin  increased by $42.1
million or 94% from the prior year  period.  Average  day rates for the  current
year  period  increased  53% from the  prior  year  while  utilization  remained
constant at 100%.  The ENSCO 100  contributed  $7.2 million in revenues and $6.6
million in operating margin to the results of the current year period. Operating
expenses  increased by $3.8 million or 14% from the prior year period  primarily
from cost increases for operating  supplies,  repairs and replacements and wages
and benefits.

   Asia Pacific Jackup Rigs

Second  quarter  revenues  for the Asia  Pacific  jackup rigs  increased by $4.0
million or 22% and the  operating  margin  increased by $4.3 million or 52% from
the prior year quarter. The increase in revenues is due to a 42% increase in day
rates,  offset in part by a decrease in  utilization  to 65% in the current year
quarter from 78% in the prior year quarter.  The decrease in  utilization is due
primarily to increased  shipyard  downtime  resulting  from two rigs  undergoing
modifications and enhancements  during the entire second quarter of 1998 and two
rigs  coming  off  contract  in June  1998.  The  enhancements  to the two  rigs
currently in the shipyard will be completed during the third quarter of 1998. At
the present  time the Company  does not have  contracts  for these rigs when the
shipyard  enhancements  are completed,  or for the two rigs whose contracts were
completed in June 1998.

<PAGE>


For the six months  ended June 30, 1998,  revenues  for the Asia Pacific  jackup
rigs  increased by $13.8  million or 44% and the operating  margin  increased by
$14.3 million or 134% from the prior year period.  Average day rates for the six
months ended June 30, 1998 increased by 43% while  utilization  decreased to 68%
from 70% in the prior year period, primarily resulting from shipyard downtime.

   South America Barge Rigs

Second quarter revenues for the South America barge rigs remained flat while the
operating  margin  decreased by $1.5 million or 13% from the prior year quarter.
The  lack  of   revenue   growth   and  the   decrease   in   operating   margin
quarter-over-quarter  is due primarily to the expiration of the initial contract
periods on two of the barge rigs in March and April 1998 and two more barge rigs
in June 1998.  These four rigs have been  working  at  reduced  day rates  under
contract extensions, which has negatively impacted revenues and operating margin
in the current quarter.

For the six months ended June 30, 1998, revenues increased by $2.3 million or 6%
and the  operating  margin  decreased by $2.8 million or 11% from the prior year
period.  The  increase in  revenues  for the  current  year six month  period is
attributable  to  increased  revenues  in the first  quarter of 1998,  resulting
primarily from  inflationary  day rate increases  prior to the expiration of the
initial contract terms of the four barge rigs discussed above. Historically, the
Company has been able to recover  inflationary  cost increases  through day rate
adjustments as provided for under the contract with Petroleos de Venezuela, S.A.
("PDVSA").  Also, in the first quarter of 1997, the Company collected additional
revenues related to catch-up adjustments of prior inflationary cost increases.

As stated above, four of the Company's ten barge rigs in Venezuela are operating
under contract extensions as their initial contract periods have expired.  PDVSA
has informed  the Company of its intent to purchase  these four rigs as provided
for under the terms of the original contract;  however,  it is uncertain whether
the purchase of the rigs will be consummated by PDVSA. The Company and PDVSA are
currently  negotiating  the  purchase  price  of the rigs  but  there  can be no
assurance  that the  parties  will reach  agreement.  If PDVSA  consummates  the
purchase  of any of the rigs,  the  Company  expects to  recognize a gain on the
sale.  If the rigs are not purchased by PDVSA then the Company will pursue other
alternatives including new drilling contracts with PDVSA or contracting the rigs
to third parties.  Management  currently  expects that the rigs will continue to
work for PDVSA under contract extensions until a final decision is reached.

For the second quarter of 1998, revenues for the Company's marine transportation
segment  remained flat and the operating margin decreased by $1.6 million or 11%
from  the  prior  year  quarter.   Second  quarter  revenues  reflect  day  rate
improvements of approximately 11%, on average, from the prior year quarter and a
decrease in utilization to 83% in the current year quarter from 93% in the prior
year  quarter.  The  decrease in  utilization  is  primarily  due to a scheduled
increase in  drydockings  in the second  quarter of 1998 compared with the prior
year quarter.  Operating expenses increased from the prior year primarily due to
increased wages and benefits and increased costs resulting from drydockings.

For the six months ended June 30, 1998,  revenues  increased $4.7 million or 11%
and the  operating  margin  increased  by $1.0 million or 4% from the prior year
period.  The  increase  in revenues is  primarily  due to a 19%  increase in day
rates,  offset in part by a decrease in  utilization  to 86% in the current year
period  from 93% in the prior  year  period.  The  decrease  in  utilization  is
primarily due to more scheduled drydockings in 1998 than 1997.

Depreciation and Amortization

For the second  quarter and six months  ended June 30,  1998,  depreciation  and
amortization  expense  decreased by $5.6 million or 22% and by $10.0  million or
20%,  respectively,  compared  with the same  periods in the prior  year.  These
decreases  are  due  primarily  to a  change  in the  depreciable  lives  of the
Company's  drilling rigs and marine vessels effective January 1, 1998, offset in
part by an increase  in property  and  equipment  balances  from the prior year.
Based on an  engineering  and economic  study of the Company's  asset base,  the
depreciable  lives of the Company's  drilling rigs and marine  vessels have been
extended  by an average of five to six years.  The effect of this  change on the
Company's  financial  results for the quarter and six months ended June 30, 1998
was to  reduce  depreciation  expense  by $10.0  million  or $.07 per  basic and
diluted  share  and by  $20.0  million  or $.14 per  basic  and  diluted  share,
respectively.

The Company's  interest  income  increased for the second quarter and six months
ended June 30, 1998 over the  comparable  prior year  periods  primarily  due to
higher average cash balances in the current year.

Interest expense  increased for the second quarter and six months ended June 30,
1998 over the comparable  prior year periods due to higher average debt balances
primarily  resulting  from the  Company's  issuance  of $300  million of debt in
November 1997.

Provision for Income Taxes

The  Company's  effective  tax rate for the second  quarter and six months ended
June 30, 1998 was  approximately  34% compared to 38% in the prior year periods.
The decrease in the  effective  tax rate is primarily due to lower foreign taxes
in the current year periods.

LIQUIDITY AND CAPITAL RESOURCES

Cash Flow and Capital Expenditures

The Company's  cash flow from  operations and capital  expenditures  for the six
months ended June 30, 1998 and 1997 were as follows (in millions):


                                                          1998           1997

                                                         $152.1         $114.0

Cash flow from  operations  increased by $127.4 million for the six months ended
June 30, 1998 as compared to the prior year  period.  The  increase in cash flow
from  operations  is  primarily a result of increased  operating  margins in the
first six months of 1998 and the net change in various working capital accounts.




<PAGE>


Management   anticipates   that   capital   expenditures   in  1998,   excluding
acquisitions,  will be approximately $355 million,  represented by approximately
$40 million for sustaining  operations,  $150 million for  enhancements and $165
million for new construction projects. The Company may spend additional funds to
acquire  rigs  or  vessels  in  1998,   depending  on  market   conditions   and
opportunities. The Company is currently constructing three barge rigs as well as
a harsh-environment  jackup rig. In May 1998, the Company was awarded a contract
by Burlington Resources for a deep water semisubmersible drilling rig. ENSCO has
contracted with a shipyard to build this semisubmersible drilling rig which will
have water  depth  capabilities  up to 7,500  feet.  ENSCO  expects to  complete
construction  of the rig in  approximately  two years.  The primary  term of the
contract is for three  years,  during  which time the Company  anticipates  that
revenues could be approximately $187 million.

Financing and Capital Resources

The Company's  long-term debt,  total capital and debt to capital ratios at June
30,  1998 and  December  31,  1997 are  summarized  below (in  millions,  except
percentages):

                                                June 30,          December 31,
                                                  1998                1997
                                               ----------         ------------

Long-term debt                                  $  388.8           $   400.8
Total capital                                    1,619.6             1,477.5
Long-term debt to total capital                      24%                 27%

The decrease in long-term debt is due primarily to debt  repayments in the first
six months of 1998. The total capital of the Company  increased due primarily to
the profitability of the Company for the first six months of 1998 offset in part
by reductions in long-term debt and stock repurchases.

In May 1998, the Company's Board of Directors authorized the repurchase of up to
five million shares of the Company's  common stock to offset the dilutive effect
of shares issued under various benefit plans and to capitalize on the attractive
valuation of the Company's  common stock.  As of June 30, 1998,  the Company had
repurchased  386,500 shares of its common stock at a cost of approximately  $7.7
million.

In May 1998, the Company entered into a $185 million unsecured  revolving credit
agreement  (the  "Credit  Agreement")  with a  syndicate  of banks.  Interest on
amounts  borrowed  under the  Credit  Agreement  will be based on LIBOR  plus an
applicable margin rate (currently .4%) depending on the Company's credit rating.
The Company also pays a commitment fee (currently .15% per annum) on the undrawn
portion of the  available  credit  line,  which is also  based on the  Company's
credit rating.  The Company is required to maintain certain financial  covenants
under the Credit  Agreement  which include the Company meeting a specified level
of interest coverage,  assets to indebtedness,  leverage ratio, and tangible net
worth.  As of June  30,  1998,  the  Company  had  $185  million  available  for
borrowings under the Credit Agreement. The Credit Agreement matures in May 2003.

The  Company's  liquidity  position  at June 30, 1998 and  December  31, 1997 is
summarized in the table below (in millions, except ratios):


                                                  June 30,        December 31,
                                                    1998              1997
                                                 ------------     ------------

          Cash and cash equivalents                 $351.3            $262.2
          Working capital                            343.8             316.2
          Current ratio                                2.9               3.4

Management  believes cash flow from  operations,  the Company's  existing Credit
Agreement and the  Company's  working  capital  should be sufficient to fund the
Company's short and long-term liquidity needs.

MARKET RISKS

The Company uses financial instruments to hedge its known liabilities in foreign
currencies  and certain  projected  foreign  currency  payments to mitigate  its
exposure to changes in those foreign currencies. The Company does not enter into
financial instruments for speculative or trading purposes. At June 30, 1998, the
Company had various foreign currency exchange contracts  outstanding to exchange
U.S. Dollars for Dutch Guilders,  British Pounds Sterling and Singapore  Dollars
totaling  $43.2  million  combined.  At June 30,  1998  there  were no  material
unrealized gains or losses on open foreign currency exchange  derivative hedges.
Management  believes  that the  Company's  hedging  activities do not expose the
Company to any material interest rate risk, foreign currency exchange rate risk,
commodity price risk or any other market rate or price risk.

YEAR 2000 ISSUE

The Company has  completed the initial  assessment  of its computer  systems and
other  operational  equipment to determine  what  systems and  equipment  may be
impacted by the Year 2000 problem.  The Company presently  believes that it will
be  able  to  implement   successfully   the  required   systems  and  equipment
modifications  necessary  to make the Company  Year 2000  compliant by mid-1999.
Based on the Company's  assessment of its computer systems and other operational
equipment to date, the Company believes that the potential impact, if any, of it
not  timely  implementing  the  necessary  modifications  to  become  Year  2000
compliant  would not be material to the  operations of the Company.  The Company
currently estimates that it will incur costs of approximately $500,000 to become
Year 2000 compliant.

The Company has initiated formal  communication with its significant  suppliers,
customers and business  partners to determine the extent to which the Company is
vulnerable to these third parties' failure to remedy their own Year 2000 issues.
In addition,  third party  vendors of hardware and packaged  software  have been
contacted about their  products'  compliance  status.  There can be no guarantee
that the systems of other companies on which the Company's  systems rely will be
timely  converted,  or that a  failure  to  convert  by  another  company,  or a
conversion that is  incompatible  with the Company's  systems,  would not have a
material adverse effect on the Company.

OUTLOOK AND FORWARD-LOOKING STATEMENTS

With oil prices remaining at very depressed levels,  management anticipates that
the Company will  experience  further  decreases in day rates and utilization in
the near-term.  As day rates and utilization continue to decrease, the Company's
financial  results will be adversely  affected.  Due to the short-term nature of
many of the Company's contracts and the unpredictable  nature of oil and natural
gas prices,  which affect the demand for drilling  activity,  the extent of such
adverse change cannot be accurately  predicted.  However,  the Company currently
anticipates  that its  financial  results  for the  second  half of 1998 will be
significantly lower than the results for the first half of 1998. The duration of
this market downturn  depends on many  factors  that also cannot be  accurately
predicted.  Management  anticipates  that the offshore  drilling markets will be
unsettled  for at  least  the  balance  of 1998,  but  remains  positive  on the
long-term outlook for the industry and for ENSCO.

The declines  experienced in the offshore drilling markets have had the greatest
impact on the demand  for the  Company's  jackup  rigs in the Gulf of Mexico and
Southeast Asia. The Company  currently has three jackup rigs idle in the Gulf of
Mexico where the Company's  contracts have traditionally been and continue to be
short-term  contracts.  Due to the  short-term  nature of these  contracts,  the
Company  expects that its Gulf of Mexico jackup rigs will  experience  increased
downtime for the  remainder of 1998.  In the Asia  Pacific  region,  the Company
currently has two rigs idle and two rigs in the shipyard. In Europe, the Company
anticipates  that one rig  will be idle  during  part of the  third  and  fourth
quarters of 1998.  In South  America,  the Company is  uncertain  as to what the
outcome will be  regarding  whether or not PDVSA will  purchase  the  previously
discussed  four  barge  rigs  whose  initial   contract  periods  have  expired.
Management  expects that PDVSA will makes its  determination  during  1998.  The
market downturn is also affecting the Company's marine  transportation  segment,
which  currently  has 10 of its 37  vessels  available  for  work in the Gulf of
Mexico.

In May 1998,  the Company was awarded a contract by  Burlington  Resources for a
deep water semisubmersible drilling rig. ENSCO has contracted with a shipyard to
build this semisubmersible drilling rig which will have water depth capabilities
up to  7,500  feet.  ENSCO  expects  to  complete  construction  of  the  rig in
approximately  two years.  The primary  term of the contract is for three years,
during which time the Company  anticipates  that revenues could be approximately
$187 million.

Progress on the construction of the Company's three barge rigs for Venezuela and
a  harsh-environment  jackup rig are  proceeding as  scheduled.  The barge rigs,
which are being  constructed  against a long-term  contract  with  Chevron,  are
expected to be delivered in early 1999, and the harsh-environment  jackup rig is
scheduled  for  delivery in early 2000.  The Company has decided not to exercise
its option to build a second  jackup rig at the present time but has arranged to
extend  the  option   availability.   The  Company  continues  to  evaluate  its
opportunities with regard to new construction projects.

NEW ACCOUNTING PRONOUNCEMENTS

In June 1998,  the  Financial  Accounting  Standards  Board issued  Statement of
Financial Accounting  Standards No. 133, "Accounting for Derivative  Instruments
and Hedging Activities." This statement requires companies to record derivatives
on the balance sheet as assets and  liabilities,  measured at fair value.  Gains
and losses  resulting from changes in the values of those  derivatives  would be
accounted  for depending on the use of the  derivative  and whether it qualifies
for hedge  accounting.  This statement is not expected to have a material impact
on the Company's consolidated financial statements.  This statement is effective
for  fiscal  years  beginning  after  June  15,  1999,  with  earlier   adoption
encouraged.  ENSCO will adopt this accounting standard as required by January 1,
2000.

time) on the date  specified  in the  Notice of  Borrowing,  each Bank will make
available its pro rata share of each Borrowing requested to be made on such date
in the manner  provided  below.  All such amounts shall be made available to the
Administrative  Agent in immediately  available  funds at the Payment Office and
the Administrative  Agent promptly will make available to Borrower by depositing
to its  account  at the  Payment  Office  the  aggregate  of  the  Borrowing  in
immediately  available funds.  Unless the  Administrative  Agent shall have been
notified  by any Bank  prior to the date of  Borrowing  that  such Bank does not
intend  to  make  available  to the  Administrative  Agent  its  portion  of the
Borrowing to be made on such date, the Administrative Agent may assume that such
Bank has made such amount available to the Administrative  Agent on such date of
Borrowing,  and the Administrative Agent, in reliance upon such assumption,  may
(in its sole  discretion  and without any obligation to do so) make available to
Borrower such corresponding  amount. If such corresponding amount is not in fact
made available to the  Administrative  Agent by such Bank and the Administrative
Agent has made available  same to Borrower,  the  Administrative  Agent shall be
entitled to recover such corresponding  amount from such Bank. If such Bank does
not pay such  corresponding  amount  forthwith upon the  Administrative  Agent's
demand  therefor,  the  Administrative  Agent shall  promptly  (and in any event
within two (2) Business  Days from the date the  Administrative  Agent made such
funds available to Borrower) notify Borrower, and Borrower shall (within two (2)
Business  Days of receiving  such demand) pay such  corresponding  amount to the
Administrative Agent. The Administrative Agent shall also be entitled to recover
on demand  from  such Bank or  Borrower,  as the case may be,  interest  on such
corresponding  amount in  respect  of each day from the date such  corresponding
amount was made  available by the  Administrative  Agent to Borrower to the date
such corresponding  amount is recovered by the  Administrative  Agent, at a rate
per  annum  equal  to (x) if paid by such  Bank,  the  overnight  Federal  Funds
Effective Rate or (y) if paid by Borrower, the then applicable rate of interest,
calculated in accordance with Section 1.08, for the respective Loans.

            (b)  Nothing  herein  shall be deemed to  relieve  any Bank from its
obligation to fulfill its commitments hereunder or to prejudice any rights which
Borrower  may have  against  any Bank as a result  of any  default  by such Bank
hereunder.

            1.05 Notes.  (a) Borrower's  obligation to pay the principal of, and
interest  on, the Loans made by each Bank to Borrower  shall be  evidenced  by a
promissory  note duly  executed and delivered by Borrower  substantially  in the
form of Exhibit 1.05 with blanks appropriately  completed in conformity herewith
(each a "Note" and, collectively, the "Notes").

     (b) The Note issued to each Bank shall (i) be executed by Borrower, (ii) be
payable to the order of such Bank and be dated the Effective Date, (iii) be in a
stated principal amount equal to the Commitment of such Bank on such date and be
payable in the principal  amount of the Loans evidenced  thereby,  (iv)mature on

<PAGE>

the Maturity  Date, (v) bear interest as provided in the  appropriate  clause of
Section 1.08 in respect of the Base Rate Loans and Eurodollar Loans, as the case
may be, evidenced thereby, (vi) be subject to mandatory repayment as provided in
Section  4.02 and (vii) be  entitled  to the  benefits  of and  subject  to this
Agreement and the other Credit Documents.

            (c) Each Bank will note on its  internal  records the amount of each
Loan made by it and each  payment  in  respect  thereof  and will,  prior to any
transfer of any of its Notes, indicate the outstanding principal amount of Loans
evidenced thereby. Failure to make any such notation shall not affect Borrower's
obligations in respect of such Loans.

            1.06  Conversions.  Borrower shall have the option to convert on any
Business Day all or a portion at least equal to the applicable Minimum Borrowing
Amount of the  outstanding  principal  amount of the Loans into a  Borrowing  or
Borrowings  of  another  Type of Loan,  provided  that (i)  except as  otherwise
provided in Section  1.10(b),  Eurodollar  Loans may be converted into Base Rate
Loans  only on the last day of an  Interest  Period  applicable  thereto  and no
partial  conversion  of  a  Borrowing  of  Eurodollar  Loans  shall  reduce  the
outstanding  principal  amount of the  Eurodollar  Loans made  pursuant  to such
Borrowing to less than the Minimum Borrowing Amount applicable thereto,  (ii) no
Base  Rate  Loans  may be  converted  into  Eurodollar  Loans at any time when a
Default or Event of Default is in existence on the date of the conversion if the
Administrative  Agent  or  the  Required  Banks  have  determined  that  such  a
conversion  would be  disadvantageous  to the  Banks  and  (iii)  Borrowings  of
Eurodollar  Loans resulting from this Section 1.06 shall be limited in number as
provided in Section  1.02.  Each such  conversion  shall be effected by Borrower
giving the Administrative  Agent at its Notice Office,  prior to 12:00 Noon (New
York  time),  at least  three  (3)  Business  Days'  prior  written  notice  (or
telephonic notice promptly confirmed in writing) (each a "Notice of Conversion")
specifying the Loans to be so converted,  the Type of Loans to be converted into
and, if to be  converted  into a Borrowing  of  Eurodollar  Loans,  the Interest
Period to be initially  applicable thereto.  The Administrative Agent shall give
each Bank prompt  notice of any such  proposed  conversion  affecting any of its
Loans.
            1.07 Pro Rata  Borrowings.  All Loans under this Agreement  shall be
made by the Banks pro rata on the basis of their respective Commitments. No Bank
shall be responsible for any default by any other Bank in its obligation to make
Loans  hereunder and each Bank shall be obligated to make the Loans  provided to
be made by it hereunder,  regardless of the failure of any other Bank to fulfill
its Commitments hereunder.

            1.08  Interest.  (a) The unpaid  principal  amount of each Base Rate
Loan shall bear interest from the date of the Borrowing  thereof until  maturity
(whether by  acceleration  or  otherwise) at a rate per annum which shall at all
times be the Base Rate in effect from time to time.

            (b) The unpaid  principal  amount of each Eurodollar Loan shall bear
interest  from the date of the  Borrowing  thereof  until  maturity  (whether by

<PAGE>

acceleration  or  otherwise) at a rate per annum which shall at all times be the
Applicable Eurodollar Margin plus the relevant Eurodollar Rate.

            (c) All  overdue  principal  and,  to the extent  permitted  by law,
overdue  interest in respect of each Loan and any other overdue  amount  payable
hereunder  shall bear interest at a rate per annum equal to two percent (2%) per
annum in excess of the rate otherwise applicable thereto,  provided that no Loan
shall bear interest after maturity  (whether by  acceleration or otherwise) at a
rate per annum less than two percent  (2%) plus the rate of interest  applicable
thereto at maturity.

            (d)  Interest  shall  accrue  from  and  including  the  date of any
Borrowing  to but  excluding  the date of any  repayment  thereof  and  shall be
payable (i) in respect of each Base Rate Loan, quarterly in arrears on the first
day of each January, April, July and October, (ii) in respect of each Eurodollar
Loan, on the last day of each  Interest  Period  applicable  thereto and, in the
case of an Interest  Period in excess of six (6) months,  on the date  occurring
six (6) months after the first day of such Interest  Period and (iii) in respect
of each  Loan,  on any  prepayment  or  conversion  (on the  amount  prepaid  or
converted),  at maturity  (whether by acceleration or otherwise) and, after such
maturity, on demand.

            (e)  All  computations  of  interest  hereunder  shall  be  made  in
accordance with Section 12.07(b).

            (f) The Administrative Agent, upon determining the interest rate for
any Borrowing of Loans for any Interest  Period,  shall promptly notify Borrower
and the Banks thereof.

            1.09 Interest  Periods.  (a) At the time Borrower  gives a Notice of
Borrowing  or Notice of  Conversion  in respect of the making of, or  conversion
into,  a Borrowing  of  Eurodollar  Loans (in the case of the  initial  Interest
Period  applicable  thereto) or prior to 12:00 Noon (New York time) on the third
Business  Day prior to the  expiration  of an Interest  Period  applicable  to a
Borrowing of  Eurodollar  Loans,  it shall have the right to elect by giving the
Administrative  Agent written notice (or telephonic notice promptly confirmed in
writing) of the Interest  Period  applicable to such  Borrowing,  which Interest
Period shall, at the option of Borrower, be a one (1), two (2), three (3) or six
(6) month period (or, to the extent  available and at the reasonable  discretion
of the Administrative Agent, a nine (9) or twelve (12) month Interest Period or,
if each Bank agrees,  a non-standard  period).  Notwithstanding  anything to the
contrary contained above:

            (i) the initial  Interest  Period for any  Borrowing  of  Eurodollar
      Loans shall commence on the date of such Borrowing  (including the date of
      any  conversion  from a Borrowing  of Base Rate  Loans) and each  Interest
      Period occurring thereafter in respect of such Borrowing shall commence on
      the day on which the immediately preceding Interest Period expires;
<PAGE>

            (ii) if any  Interest  Period  begins on a day for which there is no
      numerically  corresponding  day in the  calendar  month at the end of such
      Interest  Period,  such Interest Period shall end on the last Business Day
      of such calendar month;

            (iii) if any Interest Period would  otherwise  expire on a day which
      is not a Business  Day,  such  Interest  Period  shall  expire on the next
      succeeding  Business  Day,  provided  that if any  Interest  Period  would
      otherwise  expire on a day which is not a Business Day but is a day of the
      month  after  which no further  Business  Day occurs in such  month,  such
      Interest Period shall expire on the immediately preceding Business Day;

            (iv) no Interest Period shall extend beyond the Maturity Date;

            (v) no Interest  Period may be elected at any time when a Default or
      Event of Default is then in existence if the  Administrative  Agent or the
      Required Banks have determined that such an election at such time would be
      disadvantageous to the Banks; and

            (vi) no more than ten (10) Interest  Periods (except as described in
      clause  (b)below)  of one (1) month may be  selected  by  Borrower  in any
      calendar year.

            (b) If upon the  expiration  of any  Interest  Period,  Borrower has
failed  to (or may not)  elect a new  Interest  Period to be  applicable  to the
respective  Borrowing of Eurodollar  Loans as provided above,  Borrower shall be
deemed to have  elected  a six (6) month  Interest  Period  for such  Borrowing,
provided that if Borrower may not elect an Interest Period as a result of clause
(a)(v) above,  Borrower will be deemed to have elected a one (1) month  Interest
Period effective as of the expiration date of such current Interest Period.

            1.10 Increased Costs, Illegality,  etc. (a) In the event that (x) in
the case of clause (i)  below,  the  Administrative  Agent or (y) in the case of
clauses  (ii)  and  (iii)  below,   any  Bank  shall  have   determined   (which
determination  shall, absent manifest error, be final and conclusive and binding
upon all parties hereto):

            (i) on any date for determining the Eurodollar Rate for any Interest
      Period  that,  by reason  of any  changes  arising  after the date of this
      Agreement  affecting the interbank  Eurodollar  market,  adequate and fair
      means do not exist for  ascertaining  the applicable  interest rate on the
      basis provided for in the definition of Eurodollar Rate; or

            (ii) at any time,  that such Bank  shall  incur  increased  costs or
      reductions in the amounts received or receivable hereunder with respect to
      any  Eurodollar  Loans (other than any increased  cost or reduction in the
      amount received or receivable resulting from the imposition of or a change
      in the  rate or basis of taxes  or  similar  charges)  because  of (x) any
      change  since  the  date  of  this  Agreement  in  any   applicable   law,
      governmental   rule,   regulation,   guideline   or   order   (or  in  the
      interpretation or administration thereof and including the introduction of

<PAGE>

      any new law or governmental  rule,  regulation,  guideline or order) (such
      as,  for  example,  but not  limited  to, a  change  in  official  reserve
      requirements,  but,  in all  events,  excluding  reserves  required  under
      Regulation D but only to the extent already included in the computation of
      the Eurodollar  Rate) and/or (y) other  circumstances  occurring after the
      date of this Agreement and affecting the interbank Eurodollar market; or

            (iii) at any time,  that the making or continuance of any Eurodollar
      Loan has become unlawful by compliance by such Bank in good faith with any
      law, governmental rule, regulation,  guideline (or would conflict with any
      such  governmental  rule,  regulation,  guideline  or order not having the
      force of law but with which such Bank customarily complies even though the
      failure to comply therewith would not be unlawful);

then, and in any such event, such Bank (or the Administrative  Agent in the case
of clause  (i) above)  shall (x) on such date and (y)  within ten (10)  Business
Days of the date on which such event no longer exists, give notice (by telephone
confirmed  in  writing)  to  Borrower  and to the  Administrative  Agent of such
determination  (which notice the Administrative Agent shall promptly transmit to
each of the  other  Banks).  Thereafter  (A) in the case of  clause  (i)  above,
Eurodollar   Loans  shall  no  longer  be  available  until  such  time  as  the
Administrative  Agent  notifies  Borrower  and the Banks that the  circumstances
giving rise to such notice by the Administrative  Agent no longer exist, and any
Notice of Borrowing or Notice of  Conversion  given by Borrower  with respect to
Eurodollar  Loans  which  have not yet been made  shall be deemed  rescinded  by
Borrower,  (B) in the case of clause  (ii)  above,  Borrower  shall,  subject to
Section  1.12(b)  (to the extent  applicable),  pay to such Bank,  upon  written
demand therefor,  such additional  amounts (in the form of an increased rate of,
or a different method of calculating,  interest or otherwise as such Bank in its
sole  discretion  shall  determine) as shall be required to compensate such Bank
for such  increased  costs or  reductions  in amounts  receivable  hereunder  (a
written notice as to the additional amounts owed to such Bank, showing the basis
for the calculation  thereof,  submitted to Borrower by such Bank shall,  absent
manifest error, be final and conclusive and binding upon all parties hereto) and
(C) in the case of clause (iii) above, Borrower shall take the actions specified
in Section  1.10(b) as promptly as possible  and, in any event,  within the time
period required by law.

            (b)  At any  time  that  any  Eurodollar  Loan  is  affected  by the
circumstances  described in Section  1.10(a)(ii) or (iii),  Borrower may (and in
the  case of a  Eurodollar  Loan  affected  pursuant  to  Section  1.10(a)(iii),
Borrower  shall) either (i) if the affected  Eurodollar  Loan is then being made
pursuant to a  Borrowing,  cancel said  Borrowing  by giving the  Administrative
Agent telephonic notice (confirmed promptly in writing) thereof on the same date
that Borrower was notified by a Bank pursuant to Section  1.10(a)(ii)  or (iii),
or (ii) if the affected Eurodollar Loan is then outstanding, upon at least three
(3) Business Days' notice to the Administrative Agent, require the affected Bank
to convert each such  Eurodollar  Loan into a Base Rate Loan,  provided  that if
more than one (1) Bank is affected at any time,  then all affected Banks must be
treated the same pursuant to this Section 1.10(b).
<PAGE>

            (c) If any Bank shall have determined that after the Effective Date,
the  adoption  or  effectiveness  of any  applicable  law,  rule  or  regulation
regarding  capital  adequacy,  or  any  change  therein,  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 such Bank with any request or  directive  regarding
capital  adequacy  (whether  or not  having the force of law but with which such
Bank customarily  complies even though the failure to comply therewith would not
be unlawful) of any such authority,  central bank or comparable  agency,  has or
would have the effect of reducing  the rate of return on such Bank's  capital or
assets as a consequence of its  commitments or obligations  hereunder to a level
below  that  which  such  Bank  could  have  achieved  but  for  such  adoption,
effectiveness,  change or  compliance  (taking  into  consideration  such Bank's
policies with respect to capital  adequacy),  then from time to time,  within 15
days  after  demand  by such  Bank  (with a copy to the  Administrative  Agent),
Borrower agrees,  subject to Section 1.12(b) (to the extent applicable),  to pay
to such Bank such additional  amount or amounts as will compensate such Bank for
such reduction.  Each Bank,  upon  determining in good faith that any additional
amounts  will be payable  pursuant to this  Section  1.10(c),  will give written
notice  thereof  (such notice to be given in  accordance  with  Section  1.12(b)
below) to Borrower, which notice shall set forth the basis of the calculation of
such additional amounts.

            1.11  Compensation.  Borrower shall  compensate  each Bank, upon its
written  request (which  request shall set forth the basis for  requesting  such
compensation),  for all reasonable losses,  expenses and liabilities (including,
without  limitation,  any loss,  expense or liability  incurred by reason of the
liquidation or  reemployment of deposits or other funds required by such Bank to
fund its  Eurodollar  Loans but  excluding in any event the loss of  anticipated
profits)  which  such Bank may  sustain:  (i) if for any  reason  (other  than a
default by such Bank or the  Administrative  Agent) a  Borrowing  of  Eurodollar
Loans does not occur on a date  specified  therefor in a Notice of  Borrowing or
Notice of Conversion  (whether or not withdrawn by Borrower or deemed  withdrawn
pursuant to Section 1.10(a); (ii) if any prepayment,  repayment or conversion of
any of its Eurodollar  Loans (including as a result of Section 1. 10 or the last
paragraph of Section 9 occurs on a date which is not the last day of an Interest
Period  applicable  thereto;  (iii)  if any  prepayment  of  any  of  Borrower's
Eurodollar  Loans is not made on any date  specified  in a notice of  prepayment
given by Borrower; or (iv) as a consequence of (x) any other default by Borrower
to repay its  Eurodollar  Loans when required by the terms of this  Agreement or
(y) an election made pursuant to Section 1.10(b).

            1.12 Change of Lending Office;  Limitation on Indemnities.  (a) Each
Bank agrees that,  upon the occurrence of any event giving rise to the operation
of Section  1.10(a)(ii)  or (iii),  1.10(c),  2.05 or 4.04 with  respect to such
Bank,  it will, if requested by Borrower,  use  reasonable  efforts  (subject to
overall policy  considerations of such Bank) to designate another lending office
for any Loans or Letters of Credit  affected by such event,  provided  that such
designation  is made on such terms that such Bank and its lending  office suffer
no economic, legal or regulatory  disadvantage,  with the object of avoiding the
consequence  of the event  giving  rise to the  operation  of any such  Section.
Nothing in this Section 1.12 shall affect or postpone any of the  obligations of
Borrower or the right of any Bank provided in Section 1.10, 2.05 or 4.04.
<PAGE>

            (b) Notwithstanding  anything in this Agreement to the contrary,  to
the extent any notice  required  by Section  1.10,  2.05 or 4.04 is given by any
Bank more than 90 days after  such Bank  obtained,  or  reasonably  should  have
obtained, knowledge of the occurrence of the event giving rise to the additional
costs of the type described in such Section,  such Bank shall not be entitled to
compensation  under  Section  1.10,  2.05 or 4.04 for any  amounts  incurred  or
accruing prior to the giving of such notice to Borrower.

            1.13  Replacement of Banks.  Upon the occurrence of any event giving
rise to the operation of Section  1.10(a)(ii)  or (iii),  1.10(c),  2.05 or 4.04
with  respect  to any Bank  which  results  in such Bank  charging  to  Borrower
increased costs in excess of those being generally charged by the other Banks or
such Bank becoming  incapable of making Eurodollar Loans, as provided in Section
12.12(b), or in the case of a refusal by a Bank to consent to a proposed change,
waiver,  discharge or termination  with respect to this Agreement which has been
approved by the Required Banks,  Borrower shall have the right, if no Default or
Event of Default then exists,  to replace such Bank (the  "Replaced  Bank") with
one or more other Eligible  Transferee or Transferees  reasonably  acceptable to
the Administrative Agent (collectively,  the "Replacement Bank"),  provided that
(i) at  the  time  of  any  replacement  pursuant  to  this  Section  1.13,  the
Replacement  Bank  shall  enter  into  one or  more  Assignment  and  Assumption
Agreements  pursuant to Section  12.04(b) (and with all fees payable pursuant to
said Section 12.04(b) to be paid by the Replacement  Bank) pursuant to which the
Replacement Bank shall acquire all of the Commitments and outstanding  Loans of,
and in each case  participations  in  Letters  of  Credit  transferred  by,  the
Replaced Bank and, in connection  therewith,  shall pay to (x) the Replaced Bank
in respect  thereof an amount equal to the sum of (A) the  principal of, and all
accrued interest on, all outstanding  Loans of the Replaced Bank, (B) all Unpaid
Drawings that have been funded by (and not  reimbursed  to) such Replaced  Bank,
together with all then unpaid interest with respect thereto at such time and (C)
all accrued, but theretofore unpaid, Fees owing to the Replaced Bank pursuant to
Section  3.01,  and (y) the  Letter  of Credit  Issuer  an amount  equal to such
Replaced Bank's  Percentage of any Unpaid Drawing (which at such time remains an
Unpaid  Drawing) to the extent such  amount was not  theretofore  funded by such
Replaced Bank,  and (ii) all  obligations of Borrower owing to the Replaced Bank
(other than those specifically described in clause (i) above in respect of which
the assignment purchase price has been, or is concurrently being, paid) shall be
paid in full to such Replaced Bank  concurrently  with such replacement and such
Replaced Bank shall  promptly  return all canceled  Notes to Borrower.  Upon the
execution of the respective Assignment and Assumption Agreements, the payment of
amounts  referred to in clauses (i) and (ii) above,  and, if so requested by the
Replacement Bank, delivery to the Replacement Bank of appropriate Notes executed
by Borrower, the Replacement Bank shall become a Bank hereunder and the Replaced
Bank  shall  cease to  constitute  a Bank  hereunder,  except  with  respect  to
indemnification provisions applicable to the Replaced Bank under this Agreement,
which shall survive as to such Replaced Bank as described herein.

      SECTION 2.   Letters of Credit.

            2.01  Letters  of  Credit.  (a)  Subject  to and upon the  terms and
conditions  herein set forth,  Borrower  may  request  that the Letter of Credit
Issuer at any time and from time to time,  on or after  the  Effective  Date and

issued,  the Stated  Amount of which,  when added to all other Letters of Credit
Outstanding  (exclusive of Unpaid  Drawings which are repaid on the date of, and
prior to the issuance of, the respective Letter of Credit),  at such time, would
exceed (y)  $75,000,000.00 or (z) when added to the sum of all Letters of Credit
Outstanding  plus the aggregate  principal amount of all Loans made by the Banks
then  outstanding,  the Total  Commitment at such time;  and (ii) each Letter of
Credit shall have an expiry date occurring not later than the earlier of (y) the
date which  occurs  eighteen  (18) months  after the date of  issuance  thereof,
provided,  subject to the limits of subsection (z), below, such Letter of Credit
may contain  provisions for automatic renewal thereof on terms acceptable to the
Letter of Credit  Issuer or (z) the  Business  Day ten (10) days  preceding  the
Maturity Date.

            (c) Any  presentment  of any Letter of Credit for  payment  shall be

and any accompanying  documentation,  a sight draft in the amount of the payment
requested.

            2.02 Letter of Credit  Requests;  Request for  Issuance of Letter of
Credit.  (a)  Whenever  Borrower  desires  that a Letter of  Credit  be  issued,
Borrower shall give the Letter of Credit Issuer written notice (including by way
of  telecopier)  in the form of Exhibit 2.02 prior to 12:00 Noon (New York time)
at least seven (7) Business  Days (or three (3) Business Days if the issuance of
the  Letter of Credit  has been  approved  in  advance  by the  Letter of Credit
Issuer) prior to the proposed  date of issuance  (which shall be a Business Day)
(each a "Letter  of Credit  Request"),  which  Letter  of Credit  Request  shall
include any documents that the Letter of Credit Issuer may reasonably require in
connection  therewith.  The  Letter  of Credit  Request  shall  after  three (3)
Business  Days (or one (1)  Business Day if the issuance of the Letter of Credit
has been approved in advance by the Letter of Credit Issuer) be irrevocable.

            (b) The Letter of Credit Issuer shall,  promptly  after issuance of,
or amendment  to, a Letter of Credit by it, give each Bank and Borrower  written
notice of the issuance of, or amendment to, such Letter of Credit. Notice to the
Borrower  shall be  accompanied  by a copy of the  Issued  Letter  of  Credit or
amendment.  If  requested  to do so, the Letter of Credit  Issuer  will  provide

<PAGE>

            2.03  Agreement  to Repay  Letter of Credit  Payments.  (a) Borrower
hereby agrees to reimburse the Letter of Credit Issuer, by making payment to the
Administrative Agent at the Payment Office, for any payment or disbursement made
by the Letter of Credit  Issuer  under any Letter of Credit (each such amount so
paid or disbursed until reimbursed,  an "Unpaid Drawing") immediately after, and
in any event on the date on which  Borrower  is notified by the Letter of Credit
Issuer of such payment or  disbursement  with  interest on the amount so paid or
disbursed by the Letter of Credit Issuer,  to the extent not reimbursed prior to
1:00 P.M. (New York time) on the date of such payment or disbursement,  from and
including the date paid or disbursed to but not including the date the Letter of
Credit Issuer is reimbursed therefor at a rate per annum which shall be the Base
Rate as in effect on the date of such notice of payment or disbursement (plus an
additional 2% per annum if not  reimbursed  by the third  Business Day after the
date of such  notice of  payment  or  disbursement),  such  interest  also to be
payable on demand.

            (b) (i) The Letter of Credit  Issuer  shall not concern  itself with
the regularity or propriety of any demand made under any Letter of Credit beyond
the face thereof,  provided that such demand strictly complies with the terms of
such  Letter of Credit  and  (subject  to the  provisos  contained  in  Sections
2.03(b)(i)  and  (ii)) it shall  not be a  defense  to a claim of the  Letter of
Credit  Issuer made  pursuant to Section  13.01 that the Letter of Credit Issuer
could have  resisted  the  payment  in respect of which such claim is made.  The
Borrower will promptly  examine all  instruments and documents from time to time
delivered by the Letter of Credit Issuer to the Borrower and will,  within three
(3) Business Days of such receipt, notify the Letter of Credit Issuer in writing
of any claim of  non-compliance  with the  Letter  of  Credit or the  Borrower's
instructions  to the  Letter of Credit  Issuer  or other  irregularity,  and the
Borrower  shall  conclusively  be deemed to have  waived any claim  against  the
Letter of Credit Issuer and its  correspondents  hereunder unless such notice is
given by the Borrower as aforesaid.

            (ii) Borrower's  obligation under this Section 2.03 to reimburse the
Letter of Credit  Issuer with  respect to Unpaid  Drawings  (including,  in each
case,  interest thereon) shall be absolute and  unconditional  under any and all
circumstances and irrespective of any setoff, counterclaim or defense to payment
which  Borrower may have or have had against the Letter of Credit  Issuer or any
Bank, including,  without limitation,  any defense based upon the failure of any
drawing under a Letter of Credit to conform to the terms of the Letter of Credit
(other than the  failure of the Letter of Credit  Issuer to  determine  that any
documents  required  to be  delivered  under  such  Letter of  Credit  have been
delivered and that they substantially comply on their face with the requirements
of such  Letter of  Credit)  or any  non-application  or  misapplication  by the
beneficiary of the proceeds of such drawing; provided, however,  notwithstanding
the terms of Section 2.04(b)(i) Borrower shall not be obligated to reimburse the
Letter of Credit  Issuer for any  wrongful  payment made by the Letter of Credit
Issuer  under a Letter of Credit as a result of acts or  omissions  constituting
willful  misconduct  or gross  negligence  on the part of the  Letter  of Credit
Issuer  as  determined  in a  final,  non-appealable  judgment,  by a  court  of
competent jurisdiction.
<PAGE>

            2.04  Letter  of Credit  Participations.  (a)  Immediately  upon the
issuance by the Letter of Credit  Issuer of any Letter of Credit,  the Letter of
Credit  Issuer shall be deemed to have sold and  transferred  to each Bank,  and
each Bank (each a "Participant") shall be deemed irrevocably and unconditionally
to have  purchased  and  received  from the  Letter  of Credit  Issuer,  without
recourse or warranty, an undivided interest and participation,  to the extent of
such Bank's  Percentage,  in such Letter of Credit,  each  substitute  letter of
credit,  each drawing made thereunder and the obligations of Borrower under this
Agreement  with  respect  thereto  (although  the  Letter of Credit Fee shall be
payable directly to the Administrative Agent for the account of the Participants
as  provided  in Section  3.01(b)  and the  Participants  shall have no right to
receive any portion of any fronting fees) and any security  therefor or guaranty
pertaining  thereto.  Upon any change in the  Commitments  or Percentages of the
Banks pursuant to Section  12.04(b),  it is hereby agreed that,  with respect to
all outstanding Letters of Credit and Unpaid Drawings thereon, there shall be an
automatic  adjustment  to the  participations  pursuant to this  Section 2.04 to
reflect the new  Percentages of the assigning and assignee Bank or of all Banks,
as the case may be.

            (b) In  determining  whether to pay under any Letter of Credit,  the
Letter of Credit Issuer shall not have any obligation relative to the respective
Participants other than to determine that any documents required to be delivered
under such  Letter of Credit  have been  delivered  and that they  substantially
comply on their face with the requirements of such Letter of Credit.  Any action
taken  or  omitted  to be taken  by the  Letter  of  Credit  Issuer  under or in
connection  with any  Letter of Credit,  if taken or  omitted in the  absence of
gross negligence or willful misconduct (as determined in a final, non-appealable
judgment by a court of competent jurisdiction),  shall not create for the Letter
of Credit Issuer any resulting liability to the respective Participants.

            (c) In the event that the Letter of Credit  Issuer makes any payment
under any Letter of Credit and Borrower shall not have reimbursed such amount in
full to the Letter of Credit Issuer pursuant to Section  2.03(a),  the Letter of
Credit Issuer shall promptly notify each respective Participant of such failure,
and each such Participant shall promptly and  unconditionally  pay to the Letter
of Credit Issuer, the amount of such Participant's Percentage of such payment in
US Dollars and in same day funds;  provided,  however, that no Participant shall
be  obligated  to pay to the  Letter of Credit  Issuer  its  Percentage  of such
unreimbursed amount for any wrongful payment made by the Letter of Credit Issuer
under a Letter of Credit as a result of acts or omissions  constituting  willful
misconduct  or gross  negligence  on the part of the Letter of Credit Issuer (as
determined  in  a  final,  non-appealable  judgment  by  a  court  of  competent
jurisdiction).  If the Administrative Agent so notifies any Participant required
to fund an Unpaid  Drawing under a Letter of Credit prior to 1:00 P.M. (New York
time) on any Business Day, such  Participant  shall make available to the Letter
of Credit Issuer such Participant's  Percentage of the amount of such payment on
such Business Day in same day funds. If and to the extent such Participant shall
not have so made its Percentage of the amount of such Unpaid  Drawing  available
to the Letter of Credit Issuer,  such Participant agrees to pay to the Letter of
Credit Issuer,  forthwith on demand such amount, together with interest thereon,
for each day from such date until the date such  amount is paid to the Letter of
Credit Issuer at the overnight  Federal Funds Effective Rate. The failure of any

<PAGE>

Participant  to make  available to the Letter of Credit Issuer its Percentage of
any  Unpaid  Drawing  under any  Letter of Credit  shall not  relieve  any other
Participant  of its  obligation  hereunder  to make  available  to the Letter of
Credit  Issuer its  Percentage  of any payment under any Letter of Credit on the
date required,  as specified above, but no Participant  shall be responsible for
the failure of any other  Participant  to make available to the Letter of Credit
Issuer such other Participant's Percentage of any such payment.

            (d)  Whenever  the Letter of Credit  Issuer  receives a payment of a
reimbursement  obligation as to which the Administrative  Agent has received for
the account of the Letter of Credit  Issuer any payments  from the  Participants
pursuant  to clause (c) above,  the  Letter of Credit  Issuer  shall pay to each
respective  Participant  which has paid its Percentage in US Dollars and in same
day funds,  an amount equal to such  Participant's  Percentage  of the principal
amount  thereof and interest  thereon  accruing at the  overnight  Federal Funds
Effective Rate after the purchase of the respective participations.

            (e) The obligations of the respective  Participants to make payments
to the Letter of Credit  Issuer  with  respect  to  Letters  of Credit  shall be
irrevocable  and not subject to  counterclaim,  set-off or other  defense or any
other qualification or exception  whatsoever (provided that no Participant shall
be required to make payments  resulting from the Letter of Credit Issuer's gross
negligence  or willful  misconduct,  as  determined  in a final,  non-appealable
judgment by a court of competent  jurisdiction)  and shall be made in accordance
with the  terms  and  conditions  of this  Agreement  under  all  circumstances,
including, without limitation, any of the following circumstances:

            (i)   any lack of validity or  enforceability of this Agreement or
      any of the other Credit Documents;

            (ii) the  existence  of any claim,  set-off,  defense or other right
      which  Borrower  may have at any time  against  a  beneficiary  named in a
      Letter of Credit,  any  transferee  of any Letter of Credit (or any Person
      for whom any such transferee may be acting), the Administrative Agent, any
      Bank or other  Person,  whether in  connection  with this  Agreement,  any
      Letter of Credit,  the transactions  contemplated  herein or any unrelated
      transactions  (including any underlying  transaction  between Borrower and
      the beneficiary named in any such Letter of Credit);

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

            (iv) the surrender or impairment of any security for the performance
      or observance of any of the terms of any of the Credit Documents; or

            (v) the occurrence of any Default or Event of Default.
<PAGE>

            2.05  Increased  Costs.  If at  any  time  after  the  date  of  the
Agreement,  the  adoption  or  effectiveness  of any  applicable  law,  rule  or
regulation,  or any  change  therein,  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 the  Letter  of  Credit  Issuer or any Bank  with any  request  or  directive
(whether  or not having  the force of law but with  which such Bank  customarily
complies even though the failure to comply  therewith  would not be unlawful) by
any such authority,  central bank or comparable  agency shall either (i) impose,
modify or make  applicable  any reserve,  deposit,  capital  adequacy or similar
requirement  against  Letters of Credit issued by the Letter of Credit Issuer or
such Bank's participation therein, or (ii) impose on the Letter of Credit Issuer
or any Bank any other conditions affecting this Agreement,  any Letter of Credit
or such Bank's participation  therein; and the result of any of the foregoing is
to  increase  the cost to the Letter of Credit  Issuer or such Bank of  issuing,
maintaining or participating in any Letter of Credit, or to reduce the amount of
any sum  received  or  receivable  by the  Letter of Credit  Issuer or such Bank
hereunder  (other than any increased cost or reduction in the amount received or
receivable  resulting from the imposition of or a change in the rate or basis of
taxes or similar  charges),  then, upon written demand to Borrower by the Letter
of  Credit  Issuer  or such  Bank (a copy of which  notice  shall be sent by the
Letter of Credit  Issuer or such  Bank to the  Administrative  Agent),  Borrower
shall, subject to Section 1.11 (to the extent applicable),  pay to the Letter of
Credit Issuer or such Bank such additional  amount or amounts as will compensate
the Letter of Credit Issuer or such Bank for such increased cost or reduction. A
certificate  submitted to Borrower by the Letter of Credit  Issuer or such Bank,
as the case may be (a copy of which  certificate  shall be sent by the Letter of
Credit  Issuer  or  such  Bank to the  Administrative  Agent),  setting  forth a
reasonable  basis for the  determination  of such  additional  amount or amounts
necessary to  compensate  the Letter of Credit  Issuer or such Bank as aforesaid
shall be conclusive and binding on Borrower absent manifest error.

            2.06 Indemnities. Borrower under each Letter of Credit hereby agrees
to reimburse  and  indemnify the Letter of Credit Issuer for and against any and
all liabilities,  obligations,  losses,  damages,  penalties,  claims,  actions,
judgments,  suits, costs, expenses or disbursements of whatsoever kind or nature
which may be imposed  on,  asserted  against or incurred by the Letter of Credit
Issuer in performing its respective duties in any way relating to or arising out
of its issuance of Letters of Credit; provided that Borrower shall not be liable
for any portion of such liabilities,  obligations,  losses, damages,  penalties,
actions,  judgments,  suits, costs, expenses or disbursements resulting from the
Letter of Credit Issuer's gross  negligence or willful  misconduct as determined
in a final, nonappealable judgment by a court of competent jurisdiction.  To the
extent  the  Letter  of  Credit  Issuer  is not  indemnified  by  Borrower,  the
Participants  will  reimburse  and  indemnify  the Letter of Credit  Issuer,  in
proportion  to their  respective  Percentages  of the Total  Commitment  for and
against  any and  all  liabilities,  obligations,  losses,  damages,  penalties,
claims,  actions,   judgments,   suits,  costs,  expenses  or  disbursements  of
whatsoever kind or nature which may be imposed on, asserted  against or incurred
by the Letter of Credit Issuer in performing  its  respective  duties in any way
relating to or arising out of its issuance of Letters of Credit;  provided  that
no  Participants   shall  be  liable  for  any  portion  of  such   liabilities,
obligations,  losses,  damages,  penalties,  actions,  judgments,  suits, costs,
expenses or  disbursements  resulting  from the Letter of Credit  Issuer's gross

<PAGE>

negligence  or willful  misconduct  (as  determined  in a final,  non-appealable
judgment by a court of competent jurisdiction).

      SECTION 3. Fees: Commitments.

            3.01 Fees. (a) Borrower agrees to pay to the Administrative  Agent a
commitment fee (the "Commitment  Fee") pro rata for the account of each Bank for
the period from and including the Closing Date to, but not  including,  the date
the Total Commitment has been terminated, which Commitment Fee shall be equal to
the amount set forth  below as  determined  by  Borrower's  Pricing  Rating,  as
calculated for the last day of the fiscal  quarter last ended,  computed at such
rate for each day,  on the daily  amount of such Bank's  Unutilized  Commitment;
provided that, in the event a change in the Commitment Fee is made,  such change
shall not become  effective  until the date which is one (1)  Business Day after
the date upon  which the  Administrative  Agent  receives  written  notice  from
Borrower that such change is warranted:

       ----------------------------------------------------------------
       
                  Pricing              Commitment 
             Rating (higher of):          Fee:  
             ----------------           ------                     
             A-/Aa3 or higher            .125%
                 
             BBB+/Baa1                    .15%
       
             BBB/Baa2                    .175%
       
             BBB-/Baa3                    .20%
           
             BB+/Ba1                      .25%
       ----------------------------------------------------------------
Such  Commitment  Fee shall be due and payable in arrears on the first  Business
Day of each  January,  April,  July and  October  and on the date upon which the
Total Commitment is terminated.

            (b)  Borrower  agrees  to pay to the  Administrative  Agent  for the
account of each Bank, pro rata on the basis of their respective  Percentages,  a
fee in respect of each Letter of Credit (the "Letter of Credit  Fee"),  computed
at a rate per annum equal to the Applicable  Eurodollar Margin then in effect on
the daily Stated Amount of such Letter of Credit.  Accrued Letter of Credit Fees
shall be due and payable  quarterly in arrears on the first Business Day of each
January,  April,  July and  October  of each year and on the first day after the
Total Commitment is terminated and no Letters of Credit remain outstanding.

            (c) Borrower agrees to pay to the Letter of Credit Issuer a fronting
fee equal to the greater of $500.00 or .125% of the Stated  Amount of any Letter
of Credit, payable at the time of the issuance thereof.
<PAGE>

            (d)  Borrower  shall  pay to the  Administrative  Agent  for its own
account  an  administrative  fee of  $25,000  per  year,  payable  on the  first
anniversary  following the Closing Date and on each  anniversary  thereof and on
the Maturity Date.

            (e)  Borrower  shall  pay to the  Administrative  Agent  for its own
account such other Fees for the  administration  of this  Agreement as have been
heretofore agreed in writing by Borrower and the  Administrative  Agent when and
as due.

            (f) All  computations  of Fees  shall  be  made in  accordance  with
Section 12.07(b).

            3.02  Voluntary  Reduction of  Commitments.  Upon at least three (3)
Business Days' prior written notice (or telephonic  notice confirmed in writing)
to  the   Administrative   Agent  at  its  Notice   Office   (which  notice  the
Administrative  Agent shall  promptly  transmit to each of the affected  Banks),
Borrower  shall have the right,  without  premium or penalty,  to  terminate  or
partially  reduce the Total  Unutilized  Commitment,  provided that (i) any such
termination shall apply to proportionately and permanently reduce the respective
Commitment  of each  Bank,  (ii) no  such  reduction  shall  reduce  any  Bank's
Commitment to an amount that is less than the sum of (x) the  outstanding  Loans
of such Bank, plus (y) such Bank's Percentage of Letter of Credit  Outstandings,
and (iii) any partial  reduction  pursuant to this  Section 3.02 shall be in the
amount of at least $5,000,000.

            3.03 Commitment Termination. The Total Commitment shall terminate on
the earlier of (i) the Maturity Date or (ii) unless the Required Banks otherwise
consent, the date on which any Change of Control occurs.

            SECTION 4. Payments.

            4.01 Voluntary  Prepayments.  Borrower shall have the right to repay
Loans in whole or in part, without premium or penalty,  from time to time on the
following terms and conditions: (i) Borrower shall give the Administrative Agent
at the Notice Office written notice (or telephonic notice promptly  confirmed in
writing) of its intent to prepay the Loans,  the amount of such  prepayment  and
(in the case of Eurodollar Loans) the specific Borrowing or Borrowings  pursuant
to which  made,  which  notice  shall be given  by  Borrower  at least  five (5)
Business Days prior to the date of such prepayment of Loans,  which notice shall
promptly be transmitted by the  Administrative  Agent to each of the Banks; (ii)
each partial  prepayment  of any  Borrowing  shall be in an aggregate  principal
amount of at least  $2,000,000  and,  if  greater,  in an  integral  multiple of
$2,000,000,  provided  that no  partial  prepayment  of  Eurodollar  Loans  made
pursuant to a Borrowing shall reduce the aggregate principal amount of the Loans
outstanding  pursuant  to such  Borrowing  to an amount  less  than the  Minimum
Borrowing  Amount;  (iii)  Eurodollar Loans may only be prepaid pursuant to this
Section 4.01 on the last day of the Interest Period applicable thereto; and (iv)
each  prepayment in respect of any Loans made  pursuant to a Borrowing  shall be
applied pro rata among the Banks.
<PAGE>

            4.02  Mandatory Prepayments.

            (A) Requirements:

            (a) If on any date the sum of the  aggregate  outstanding  principal
amount of Loans made by the Banks and the Letter of Credit Outstandings  exceeds
the Total  Commitment as then in effect,  Borrower  shall repay on such date the
principal of Loans of the Banks, in an aggregate amount equal to such excess.

            (b) Notwithstanding  anything to the contrary contained elsewhere in
this  Agreement,  all then  outstanding  Loans  shall be  repaid  in full on the
Maturity Date.

            (c) On the  date on which  any  Change  of  Control  occurs,  unless
otherwise  agreed by all the  Banks,  the  outstanding  principal  amount of all
Loans, if any, shall become due and payable in full.

            (d) Following an Event of Default, payments shall be required as set
forth in Section 9.
<PAGE>

            (B) Application:

            With respect to each  prepayment of Loans  required by Section 4.02,
Borrower  may  designate  the  Types of Loans  which are to be  prepaid  and the
specific  Borrowing  or  Borrowings  pursuant to which made,  provided  that (i)
Eurodollar  Loans may only be repaid if no Base Rate Loans  remain  outstanding;
(ii) if any prepayment of Eurodollar  Loans made pursuant to a single  Borrowing
shall reduce the outstanding  Loans made pursuant to such Borrowing to an amount
less than the Minimum Borrowing Amount for such Borrowing,  such Borrowing shall
be immediately  converted into Base Rate Loans; and (iii) each prepayment of any
Loans shall be applied pro rata among the Banks. In the absence of a designation
by Borrower described in the preceding sentence, the Administrative Agent shall,
subject to the above,  make such designation in its sole discretion with a view,
but no  obligation,  to  minimize  breakage  costs  owing  under  Section  1.11.
Notwithstanding the foregoing provisions of this Section 4.02(B), if at any time
the  mandatory  prepayment  of Loans  pursuant  to Section  4.02(A)  above would
result,  after giving  effect to the  procedures  set forth  above,  in Borrower
incurring  breakage  costs under  Section 1.11 as a result of  Eurodollar  Loans
being  prepaid  other  than on the last  day of an  Interest  Period  applicable
thereto  (the  "Affected  Eurodollar  Loans"),  then  Borrower  may in its  sole
discretion  initially  deposit  a  portion  (up to  100%)  of the  amounts  that
otherwise would have been paid in respect of the Affected  Eurodollar Loans with
the Administrative Agent (which deposit must be equal in amount to the amount of
the Affected  Eurodollar  Loans not immediately  prepaid) to be held as security
for  the  obligations  of  Borrower  hereunder  pursuant  to a  cash  collateral
agreement to be entered into in form and substance  reasonably  satisfactory  to
Borrower  and  the  Administrative  Agent  and  shall  provide  for  investments
satisfactory to the Administrative Agent and Borrower, with such cash collateral
to be directly applied upon the first occurrence (or occurrences)  thereafter of
the last day of an Interest  Period  applicable  to the relevant  Loans that are
Eurodollar  Loans  (or such  earlier  date or dates  as  shall be  requested  by
Borrower),  to repay an  aggregate  principal  amount of such Loans equal to the
Affected  Eurodollar  Loans not  initially  prepaid  pursuant to this  sentence.
Notwithstanding  anything to the contrary contained in the immediately preceding
sentence,  all amounts deposited as cash collateral  pursuant to the immediately
preceding  sentence  shall be held for the sole benefit of the Banks whose Loans
would  otherwise have been  immediately  prepaid with the amounts  deposited and
upon the taking of any action by the Administrative  Agent or the Banks pursuant
to the remedial  provisions  of Section 9, any amounts  held as cash  collateral
pursuant  to  this  Section  4.02(B)  shall,  subject  to  the  requirements  of
applicable law, be immediately applied to the Loans made by Borrower.

            4.03 Method and Place of Payment.  Except as otherwise  specifically
provided  herein,  all  payments  under  this  Agreement  shall  be  made to the
Administrative  Agent for the ratable  (based on its pro rata share)  account of
the Banks  entitled  thereto,  not later than 10:00 A.M.  (New York time) on the
date when due and  shall be made in  immediately  available  funds and in lawful
money of the United States of America at the Payment Office, it being understood
that written notice from Borrower to the Administrative  Agent to make a payment
from the funds in Borrower's  account at the Payment Office shall constitute the
making of such  payment to the extent of such  funds held in such  account.  Any

<PAGE>

payments  under this  Agreement  which are made later than 10:00 A.M.  (New York
time)  shall be deemed to have been made on the next  succeeding  Business  Day.
Whenever  any  payment to be made  hereunder  shall be stated to be due on a day
which is not a Business  Day, the due date thereof shall be extended to the next
succeeding  Business Day and,  with respect to payments of  principal,  interest
shall  be  payable  during  such  extension  at the  applicable  rate in  effect
immediately prior to such extension.

            4.04 Net Payments.  (a) All payments  made by Borrower  hereunder or
under any Note  will be made  without  setoff,  counterclaim  or other  defense.
Except as provided in Section  4.04(b) and (c), all such  payments  will be made
free and clear of, and without  deduction  or  withholding  for,  any present or
future taxes, levies,  imposts,  duties,  fees,  assessments or other charges of
whatever nature now or hereafter imposed by any jurisdiction or by any political
subdivision or taxing authority thereof or therein with respect to such payments
(but excluding,  except as provided in the second succeeding  sentence,  any tax
imposed on or measured  by the net income or net  profits of a Bank  pursuant to
the laws of the  jurisdiction in which it is organized or managed and controlled
or the jurisdiction in which the principal  office or applicable  lending office
of such Bank is located or any subdivision thereof or therein) and all interest,
penalties or similar  liabilities  with respect  thereto (all such  non-excluded
taxes,  levies,  imposts,  duties,  fees,  assessments  or other  charges  being
referred to  collectively  as  "Taxes").  If any Taxes are so levied or imposed,
Borrower  agrees  to pay the full  amount  of such  Taxes,  and such  additional
amounts,  if any, as may be necessary so that every payment of amounts due under
this  Agreement or under any Note,  after  withholding  or  deduction  for or on
account of any Taxes, will not be less than the amount provided for herein or in
such Note.  If any amounts are payable by Borrower in respect of Taxes  pursuant
to the preceding  sentence,  Borrower  agrees to reimburse  each Bank,  upon the
written request of such Bank, for Taxes imposed on or measured by the net income
or net profits of such Bank  pursuant to the laws of the  jurisdiction  in which
the  principal  office or applicable  lending  office of such Bank is located or
under the laws of any  political  subdivision  or taxing,  authority of any such
jurisdiction in which the principal office or applicable  lending office of such
Bank is located and for any  withholding  of Taxes as such Bank shall  determine
are payable by, or withheld  from,  such Bank in respect of such amounts so paid
to or on behalf of such Bank pursuant to the  preceding  sentence and in respect
of any  amounts  paid to or on behalf of such Bank  pursuant  to this  sentence.
Borrower will furnish to the Administrative  Agent within 45 days after the date
the payment of any Taxes is due pursuant to applicable  law certified  copies of
tax receipts  evidencing such payment by Borrower.  Borrower agrees to indemnify
and hold harmless each Bank, and reimburse  such Bank upon its written  request,
for the amount of any Taxes so levied or imposed and paid by such Bank.

            (b) Each Bank that is not a United  States  person  (as such term is
defined in Section  7701(a)(30)  of the Code)  agrees to deliver to Borrower and
the  Administrative  Agent on or prior to the date of this Agreement,  or in the
case of a Bank that is an  assignee  or  transferee  of an  interest  under this
Agreement  pursuant to Section  1.13 or 12.04  (unless the  respective  Bank was
already a Bank hereunder  immediately prior to such assignment or transfer),  on
the date of such  assignment or transfer to such Bank,  (i) two (2) accurate and
complete  original  signed copies of Internal  Revenue Service Form 4224 or 1001
(or  successor  forms)  certifying  to such  Bank's  entitlement  to a  complete

<PAGE>

exemption from United States withholding tax with respect to payments to be made
under  this  Agreement  and under any Note,  or (ii) if the Bank is not a "bank"
within the meaning of Section 881(c)(3)(A) of the Code and cannot deliver either
Internal  Revenue Service Form 1001 or 4224 pursuant to clause (i) above,  (x) a
certificate  substantially in the form of Exhibit 4.04(b) (any such certificate,
a "Section  4.04(b)(ii)  Certificate")  and (y) two (2)  accurate  and  complete
original signed copies of Internal  Revenue Service Form W-8 (or successor form)
certifying to such Bank's entitlement to a complete exemption from United States
withholding  tax with  respect to  payments  of  interest  to be made under this
Agreement  and under any Note.  In addition,  each Bank agrees that from time to
time  after  the  date of this  Agreement,  when a lapse  in time or  change  in
circumstances renders the previous  certification  obsolete or inaccurate in any
material respect,  it will deliver to Borrower and the Administrative  Agent two
(2) new accurate and complete original signed copies of Internal Revenue Service
Form 4224 or 1001,  or Form W-8 and a Section  4.04(b)(ii)  Certificate,  as the
case may be,  and such  other  forms as may be  required  in order to confirm or
establish  the  entitlement  of  such  Bank  to a  continued  exemption  from or
reduction in United States  withholding  tax with respect to payments under this
Agreement  and  any  Note,  or it  shall  immediately  notify  Borrower  and the
Administrative  Agent in writing of its  inability  to deliver  any such Form or
Certificate.  Notwithstanding  anything  to the  contrary  contained  in Section
4.04(a),  but  subject  to  Section  12.04(b)  and  the  immediately  succeeding
sentence,  (x) Borrower shall be entitled, to the extent it is required to do so
by law,  to deduct or  withhold  income or similar  taxes  imposed by the United
States (or any political  subdivision  or taxing  authority  thereof or therein)
from interest,  fees or other amounts  payable  hereunder for the account of any
Bank  which is not a United  States  person  (as such term is defined in Section
7701(a)(30) of the Code) for U.S. Federal income tax purposes to the extent that
such Bank has not provided to Borrower U.S.  Internal Revenue Service Forms that
establish  a complete  exemption  from such  deduction  or  withholding  and (y)
Borrower shall not be obligated  pursuant to Section  4.04(a) hereof to gross-up
payments to be made to a Bank in respect of income or similar  taxes  imposed by
the United  States if (I) such Bank has not  provided to Borrower  the  Internal
Revenue  Service  Forms  required to be  provided  to Borrower  pursuant to this
Section 4.04(b) or (II) in the case of a payment, other than interest, to a Bank
described in clause (ii) above, to the extent that such Internal Revenue Service
Forms do not  establish a complete  exemption  from  withholding  of such taxes.
Notwithstanding  anything to the contrary contained in the preceding sentence or
elsewhere  in this  Section  4.04 and except as set forth in  Section  12.04(b),
Borrower  agree to pay  additional  amounts  and to  indemnify  each Bank in the
manner set forth in  Section  4.04(a)  (without  regard to the  identity  of the
jurisdiction  requiring the deduction or  withholding) in respect of any amounts
deducted or withheld by it as described in the immediately preceding sentence as
a result of any changes after the date of this Agreement in any applicable  law,
treaty,   governmental  rule,   regulation,   guideline  or  order,  or  in  the
interpretation  thereof,  relating to the deducting or  withholding of income or
similar   Taxes,   provided   such  Bank  shall  provide  to  Borrower  and  the
Administrative  Agent any  applicable  IRS tax form  (reasonably  similar in its
simplicity and lack of detail to IRS Form 1001) necessary or appropriate for the
exemption or reduction in the rate of such U.S. Federal withholding tax.
<PAGE>

            (c) The  provisions of this Section 4.04 shall be subject to Section

            5.03 No Default on Effective  Date.  On the  Effective  Date,  there

            SECTION 6. Representations,  Warranties and Agreements.  In order to
induce  the Banks to enter into this  Agreement  and to make the Loans and issue
and/or participate in Letters of Credit provided for herein,  Borrower on behalf
of itself and each of its  Subsidiaries or Material or Restricted  Subsidiaries,
as   applicable,   and  each   Guarantor,   for  itself,   makes  the  following
representations  and warranties to, and agreements with, the Banks, all of which
shall survive the execution and delivery of this Agreement and the making of the
Loans  (with  the  making  of each  Credit  Event  thereafter  being  deemed  to
constitute  a  representation  and warranty  that the matters  specified in this
Section 6 are true and correct in all material respects on and as of the date of
each such  Credit  Event  unless  such  representation  and  warranty  expressly
indicates  that it is being  made as of any  specific  date,  in which case such
representations  and  warranties  shall  be true  and  correct  in all  material
respects as of such date):

            6.01  Corporate   Status.   Each  Credit  Party  and  each  Material
Subsidiary  (i) is a duly  organized and validly  existing  corporation  in good
standing  under the laws of the  jurisdiction  of its  organization  and has the
corporate power and authority to own its property and assets and to transact the
business in which it is engaged,  except in such case where the failure to be so
duly organized and validly  existing in good standing and to have such corporate
power and  authority  (x) is not  reasonably  likely to have a Material  Adverse
Effect and (y) is not reasonably likely to have a material adverse effect on the
rights or remedies of the Banks or on the ability of any Credit Party to perform
its obligations to them hereunder and under the other Credit  Documents to which
it is a party,  and (ii) is duly  qualified and authorized to do business and is
in good  standing in all  jurisdictions  where it is required to be so qualified
and where the failure to be so qualified would have a Material Adverse Effect.

            6.02  Corporate  Power  and  Authority.  Each  Credit  Party has the
corporate  power and  authority to execute,  deliver and carry out the terms and
provisions  of the  Credit  Documents  to which it is a party  and has taken all
necessary corporate action to authorize the execution,  delivery and performance
of the  Credit  Documents  to which it is a party.  Each  Credit  Party has duly

<PAGE>

executed and delivered each Credit Document to which it is a party and each such
Credit  Document  constitutes  the legal,  valid and binding  obligation of such
Credit  Party  enforceable  against  such Person in  accordance  with its terms,
except  to  the  extent  that  the  enforceability  thereof  may be  limited  by
applicable bankruptcy,  insolvency,  reorganization,  moratorium or similar laws
generally affecting creditors' rights and by equitable principles (regardless of
whether enforcement is sought in equity or at law).

            6.03 No Violation.  Neither the execution,  delivery and performance
by any  Credit  Party  of the  Credit  Documents  to  which  it is a  party  nor
compliance with the terms and provisions  thereof,  nor the  consummation of the
transactions  contemplated  therein (i) will contravene any applicable provision
of any law, statute, rule, regulation,  order, writ, injunction or decree of any
court or governmental instrumentality of the United States or any state thereof,
(ii) will  result in any breach of any of the terms,  covenants,  conditions  or
provisions  of, or  constitute  a default  under,  or result in the  creation or
imposition  of (or the  obligation to create or impose) any Lien upon any of the
property or assets of any Credit  Party  pursuant to the terms of, any  material
indenture,  mortgage,  deed of trust, agreement or other instrument to which any
Credit  Party is a party or by which it or any of its  property  or  assets  are
bound or to which it is subject  or (iii)  will  violate  any  provision  of the
Certificate of Incorporation or By-Laws of Borrower or any Credit Party.

            6.04  Litigation.  Except as otherwise  disclosed in Borrower's most
recent 10-K or 10-Q filing with the U.S.  Securities  and  Exchange  Commission,
there are no actions,  suits or proceedings pending or, to the best knowledge of
Borrower threatened with respect to Borrower or any of its Subsidiaries (i) that
are likely to have a Material Adverse Effect or (ii) that are reasonably  likely
to have a material  adverse  effect on the rights or remedies of the Banks or on
the ability of any Credit Party to perform its obligations to them hereunder and
under the other Credit Documents to which it is a party.

            6.05  Use of  Proceeds:  Margin  Regulations.  (a) The proceeds of
all Loans shall be utilized to provide for the general  corporate  purposes of
Borrower and its Subsidiaries.

            (b)  Neither  the making of any Loan  hereunder,  nor the use of the
proceeds  thereof,  will  violate  or be  inconsistent  with the  provisions  of
Regulation G, T, U or X of the Board of Governors of the Federal  Reserve System
and no part of the  proceeds  of any Loan will be used to  purchase or carry any
Margin Stock in violation of Regulation U or to extend credit for the purpose of
purchasing or carrying any Margin Stock.

            6.06  Governmental  Approvals.  Except  for  the  orders,  consents,
approvals, licenses, authorizations,  validations, recordings, registrations and
exemptions that have already been duly made or obtained and remain in full force
and effect, no order, consent, approval, license,  authorization,  or validation
of, or filing,  recording or registration  with, or exemption by, any foreign or
domestic  governmental or public body or authority,  or any subdivision thereof,
is required to authorize or is required in  connection  with (i) the  execution,
delivery and  performance  of any Credit  Document by a Credit Party or (ii) the
<PAGE>

legality,  validity,  binding effect or  enforceability  of any Credit  Document
against a Credit Party.

            6.07  Investment  Company  Act.  Neither  Borrower  nor  any  of its
Subsidiaries  is  an  "investment  company"  or a  "company"  controlled  by  an
"investment  company," within the meaning of the Investment Company Act of 1940,
as amended.

            6.08 True and Complete  Disclosure.  No  representation  or warranty
contained  in this  Agreement  and no statement  contained  in any  certificate,
schedule,  list,  financial  statement  or other  instrument  furnished by or on
behalf of Borrower or any of its  Material  Subsidiaries  to the  Administrative
Agent or any Bank contains any untrue statement of material fact,  provided that
where  a  representation  or  warranty  is made as of a  particular  date,  such
representation  or warranty  shall only be required to be true and correct as of
such date.

            6.09 Financial Condition; Financial Statements. (a) On and as of the
Effective  Date,  on a pro forma basis after giving  effect to all  Indebtedness
incurred,  and to be incurred, and Liens created, and to be created, by Borrower
and its Subsidiaries in connection  therewith,  (x) the sum of the assets,  at a
fair valuation,  of Borrower and its  Subsidiaries  taken as a whole will exceed
their debts,  (y) Borrower and its  Subsidiaries  taken as a whole will not have
incurred or intended  to, or believe  that they will,  incur debts  beyond their
ability  to pay  such  debts  as such  debts  mature  and (z)  Borrower  and its
Subsidiaries  taken as a whole will not have  unreasonably  small  capital  with
which to conduct their business.

            (b) The  consolidated,  audited  balance  sheet of Borrower  and its
Subsidiaries  as of  December  31,  1997 and the  related  consolidated  audited
statements of operations and cash flows of Borrower and its Subsidiaries for the
fiscal  year,  as the case may be,  ended as of said date,  copies of which have
heretofore been furnished to each Bank, present fairly the financial position of
such  entities  at the dates of said  statements  and the results for the period
covered  thereby in accordance  with GAAP,  except to the extent provided in the
notes to said  financial  statements.  All such financial  statements  have been
prepared in accordance  with GAAP and practices  consistently  applied except to
the  extent  provided  in the  notes  to said  financial  statements.  As of the
Effective Date,  nothing has occurred since December 31, 1997 that has had or is
reasonably likely to have a Material Adverse Effect.

            6.10 Tax  Returns  and  Payments.  Each  Credit  Party has filed all
federal  income tax returns and all other  material  tax  returns,  domestic and
foreign,  required  to be  filed  by it and has  paid  all  material  taxes  and
assessments  payable  by it which  have  become  due,  other  than those not yet
delinquent and except for those  contested in good faith.  Each Credit Party has
paid, or has provided adequate reserves with respect thereto, in accordance with
GAAP, for the payment of, all federal, state and foreign income taxes applicable
for all prior fiscal years and for the current fiscal year to the date hereof.
<PAGE>

            6.11 Compliance with ERISA. No Reportable  Event has occurred and is
continuing with respect to any Plan.

            6.12 Subsidiaries.  Annex 6.12, as supplemented or amended from time
in accordance with the terms hereof,  lists each Subsidiary of Borrower (and the
direct and indirect ownership interest of Borrower therein), and indicates which
of such Subsidiaries are Restricted Subsidiaries for purposes of this Agreement,
in each case existing on the Effective Date.

            6.13 Patents,  etc.  Each Credit Party and each Material  Subsidiary
has obtained all  material  patents,  trademarks,  service  marks,  trade names,
copyrights,  licenses and other rights, free from burdensome restrictions,  that
are  necessary  for the  operation  of  their  businesses  taken  as a whole  as
presently conducted.

            6.14 Pollution and Other Regulations.  (a) To the best of Borrower's
knowledge,  (i) each of Borrower and its Material Subsidiaries is in substantial
compliance  with all  applicable  Environmental  Laws governing its business for
which failure to comply is reasonably  likely to have a Material Adverse Effect;
and (ii) all licenses, permits,  registrations or approvals required to preserve
the ownership and  operation of the Rigs under any  Environmental  Law have been
secured. Neither Borrower nor any of its Material Subsidiaries is in any respect
in noncompliance  with,  breach of or default under any writ,  order,  judgment,
injunction,  or decree to which Borrower or such Material  Subsidiary is a party
or which would affect the ability of Borrower or such Material Subsidiary to own
or operate any Rig and no event has occurred and is continuing  which,  with the
passage of time or the giving of notice or both, would constitute noncompliance,
breach or  default  thereunder,  except in each such case,  such  noncompliance,
breaches or defaults as are not likely to have a Material Adverse Effect.  There
are as of the Effective  Date no  Environmental  Claims  pending or, to the best
knowledge  of  Borrower,  threatened,  against  Borrower or any of its  Material
Subsidiaries  wherein  an  unfavorable  decision,  ruling  or  finding  would be
reasonably likely to have a Material Adverse Effect.

            (b)  Hazardous  Materials  have not at any time been  released on or
from any  offshore  drilling  rig or vessel  at any time  owned or  operated  by
Borrower or any of its Material Subsidiaries, in each case where, to the best of
Borrower's knowledge,  such occurrence or event individually or in the aggregate
is reasonably likely to have a Material Adverse Effect.

            6.15 Properties.  (a) Borrower and each of its Material Subsidiaries
has title to all material properties owned by them, free and clear of all Liens,
other than (i) as referred to in the consolidated  balance sheet or in the notes
thereto or (ii) Permitted Liens.

            (b) Annex  6.15(b)  sets forth each Rig owned or leased by  Borrower
and each of the Restricted  Subsidiaries  on the Effective  Date, and identifies
the registered owner, flag,  official or patent number, to the extent available,
the home port and class on the Effective Date.
<PAGE>

            6.16 Citizenship.  Borrower and/or each of its Material Subsidiaries
is qualified to own and operate the Rigs and any other drilling rigs or offshore
vessels  operated by them under the laws of the United  States,  the Bahamas and
Liberia, as may be applicable.

            6.17 Rig Classification. Each Rig is classified in the highest class
available  for rigs or vessels of its age and type with the  American  Bureau of
Shipping,  Inc. or another  internationally  recognized  classification  society
reasonably   acceptable  to  the  Administrative  Agent  free  of  any  material
outstanding requirements or recommendations.

            6.18  Insurance.  Borrower and each Material  Subsidiary has insured
its  properties  and  assets  against  such  risks  and in such  amounts  as are
customary for companies engaged in similar businesses.

            6.19 Year 2000  Compliance.  Borrower has (i) initiated a review and
assessment  of all  areas  within  its and  each of its  Material  Subsidiaries'
business and operations (including those affected by suppliers and vendors) that
could be adversely  affected by the risk that computer  applications used by the
Borrower or any of its  Material  Subsidiaries  may be unable to  recognize  and
perform properly date-sensitive  functions involving any date after December 31,
1999) (the "Year 2000  Problem"),  (ii) is  developing  a plan and  timeline for
addressing  the Year  2000  Problem  on a timely  basis,  and (iii) has begun to
implement  that plan in  accordance  with that  timetable.  Borrower  reasonably
believes that all computer  applications  that are material to its or any of its
Material Subsidiaries' business and operations will on a timely basis be able to
perform properly  date-sensitive  functions for all dates after January 1, 2000,
except to the extent that a failure to do so could not reasonably be expected to
have a Material Adverse Effect.

            SECTION 7. Affirmative  Covenants.  Borrower on behalf of itself and
each of its Subsidiaries or Material or Restricted Subsidiaries,  as applicable,
and each  Guarantor for itself  covenants and agrees that on the Effective  Date
and  thereafter  for so long as this  Agreement  is in  effect  (and  until  all
Commitments have  terminated,  no Letters of Credit or Notes are outstanding and
the  Loans and  Unpaid  Drawings,  together  with  interest,  Fees and all other
Obligations incurred hereunder, are paid in full):

year-end audit adjustments.

            (c) Rig Status Report.  As soon as available and in any event within

     11.01 Appointment of the  Administratvie  Agent. The Banks hereby designate
Bankers Trust Company as Administrative  Agent to act as specified herein and in
the other Credit Documents.  Each Bank hereby irrevocably  authorizes,  and each
holder of any Note by the acceptance of such Note shall be deemed irrevocably to
authorize,  the Administrative Agent to take such action on its behalf under the
provisions  of  this  Agreement,  the  other  Credit  Documents  and  any  other
instruments  and  agreements  referred to herein or therein and to exercise such
powers and to perform such duties  hereunder and thereunder as are  specifically
delegated  to or required of the  Administrative  Agent by the terms  hereof and
thereof  and  such  other  powers  as are  reasonably  incidental  thereto.  The
Administrative  Agent may perform any of its duties  hereunder by or through its
respective officers, directors, agents, employees or Affiliates.
<PAGE>

     11.02 Nature of Duties. The Administrative  Agent shall not have any duties
or  responsibilities  except those expressly set forth in this Agreement and the
other  Credit  Documents.  Neither  the  Administrative  Agent  nor  any  of its
respective officers,  directors, agents, employees or Affiliates shall be liable
for any  action  taken or  omitted  by it or them  hereunder  or under any other
Credit Document or in connection herewith or therewith,  unless caused by its or
their gross negligence or willful  misconduct.  The duties of the Administrative
Agent shall be mechanical and administrative in nature; the Administrative Agent
shall not have by reason  of this  Agreement  or any  other  Credit  Document  a
fiduciary  relationship  in respect  of any Bank or the holder of any Note;  and
nothing in this Agreement or any other Credit Document, expressed or implied, is
intended to or shall be so construed as to impose upon the Administrative  Agent
any obligations in respect of this Agreement or any other Credit Document except
as expressly set forth herein or therein.

     11.03 Lack of  Reliance  on the  Administrative  Agent.  Independently  and
without reliance upon the Administrative Agent, each Bank and the holder of each
Note, to the extent it deems  appropriate,  has made and shall  continue to make
(i) its own independent  investigation of the financial condition and affairs of
Borrower and its  Subsidiaries in connection with the making and the continuance
of the Loans and  issuance  and/or  participation  in  Letters of Credit and the
taking or not  taking  of any  action in  connection  herewith  and (ii) its own
appraisal of the  creditworthiness  of Borrower and its Subsidiaries and, except
as expressly provided in this Agreement, the Administrative Agent shall not have
any duty or  responsibility,  either  initially  or on a  continuing  basis,  to
provide any Bank or the holder of any Note with any credit or other  information
with respect  thereto,  whether coming into its possession  before the making of
the Loans or at any time or times thereafter. The Administrative Agent shall not
be  responsible  to any  Bank  or the  holder  of any  Note  for  any  recitals,
statements,  information,   representations  or  warranties  herein  or  in  any
document,  certificate or other writing delivered in connection  herewith or for
the execution, effectiveness, genuineness, validity, enforceability, perfection,
collectibility,  priority or  sufficiency  of this Agreement or any other Credit
Document or the  financial  condition  of Borrower and its  Subsidiaries  or any
Guarantor or be required to make any inquiry  concerning  either the performance
or observance of any of the terms, provisions or conditions of this Agreement or
any other  Credit  Document,  or the  financial  condition  of Borrower  and its
Subsidiaries  or any  Guarantor or the  existence  or possible  existence of any
Default or Event of Default.

     11.04 Certain Rights of the  Administrative  Agent.  If the  Administrative
Agent shall request instructions from the Required Banks with respect to any act
or action  (including  failure to act) in connection  with this Agreement or any
other Credit  Document,  the  Administrative  Agent shall be entitled to refrain
from such act or taking such action  unless and until the  Administrative  Agent
shall have received instructions from the Required Banks; and the Administrative
Agent  shall  not incur  liability  to any  Person  by reason of so  refraining.
Without  limiting  the  foregoing,  neither  any Bank nor the holder of any Note
shall have any right of action whatsoever against the Administrative  Agent as a
result of the Administrative Agent acting or refraining from acting hereunder or

<PAGE>

under any other  Credit  Document in  accordance  with the  instructions  of the
Required Banks.

     11.05 Reliance.  The  Administrative  Agent shall be entitled to rely, and
shall be fully protected in relying, upon any note, writing, resolution, notice,
statement,  certificate,  telex,  teletype  or  telecopier  message,  cablegram,
radiogram,  order or other document or telephone message signed, sent or made by
any Person that the Administrative  Agent believed to be the proper Person, and,
with respect to all legal  matters  pertaining  to this  Agreement and any other
Credit Document and its duties hereunder and thereunder,  upon advice of counsel
selected by the Administrative Agent (which may be counsel for the Borrower).

     11.06  Idemnification.  To  the  extent  the  Administrative  Agent  is not
reimbursed and  indemnified by Borrower,  the Banks will reimburse and indemnify
the Administrative Agent, in proportion to their respective  Percentages for and
against  any and  all  liabilities,  obligations,  losses,  damages,  penalties,
claims,  actions,   judgments,   suits,  costs,  expenses  or  disbursements  of
whatsoever kind or nature which may be imposed on, asserted  against or incurred
by the  Administrative  Agent in performing its respective  duties  hereunder or
under any other Credit  Document,  in any way relating to or arising out of this
Agreement or any other Credit  Document;  provided  that no Bank shall be liable
for any portion of such liabilities,  obligations,  losses, damages,  penalties,
claims,  actions,  judgments,  suits, costs, expenses or disbursements resulting
from the Administrative Agent's gross negligence or willful misconduct.

     11.07 The Administrative Agent in Its Individual Capacity.  With respect to
its  obligation to make Loans under this  Agreement,  the  Administrative  Agent
shall have the rights and powers  specified herein for a "Bank" and may exercise
the same rights and powers as though it were not performing the duties specified
herein;  and the term  "Banks,"  "Required  Banks,"  "holders  of  Notes" or any
similar terms shall, unless the context clearly otherwise indicates, include the
Administrative  Agent in its individual  capacity.  The Administrative Agent may
accept  deposits  from,  lend  money  to,  and  generally  engage in any kind of
banking,  trust or other  business  with  Borrower  or its  Subsidiaries  or any
Affiliate thereof as if it were not performing the duties specified herein,  and
may accept fees and other consideration from Borrower or any of its Subsidiaries
or  Affiliates  for services in  connection  with this  Agreement  and otherwise
without having to account for the same to the Banks.

     11.08 Holders. The Administrative Agent may deem and treat the payee of any
Note as the owner  thereof for all  purposes  hereof  unless and until a written
notice of the assignment,  transfer or endorsement  thereof, as the case may be,
shall have been filed with the Administrative  Agent. Any request,  authority or
consent of any Person  who,  at the time of making  such  request or giving such
authority or consent,  is the holder of any Note shall be conclusive and binding
on any subsequent holder, transferee,  assignee or indorsee, as the case may be,
of such Note or of any Note or Notes issued in exchange therefor.

provided further, that no Bank shall transfer, grant or assign any participation
under which the  participant  shall have rights to approve any  amendment  to or

Note or Letters of Credit in which such participant is participating,  or reduce
the rate or extend the time of payment of  interest or Fees  thereon  (except in
connection with a waiver of the  applicability of any  post-default  increase in
interest  rates),  or reduce the  principal  amount  thereof,  or increase  such
participant's  participating  interest in any Commitment over the amount thereof
then in effect (it being  understood  that a waiver of any condition,  covenant,
Default or Event of Default or of a mandatory reduction in the Total Commitment,
or a mandatory  prepayment,  shall not  constitute  a change in the terms of any
Commitment)  or (ii) consent to the assignment or transfer by Borrower of any of
its rights and obligations under this Agreement.

            (b) Notwithstanding the foregoing,  (x) any Bank may assign all or a
portion of its outstanding  Commitment and its rights and obligations  hereunder
to  its  Affiliate  or to  another  Bank,  and  (y)  with  the  consent  of  the
Administrative  Agent and  Borrower  (which  consent  shall not be  unreasonably
withheld),  any Bank may assign all or a portion of its  outstanding  Commitment
and its rights and obligations hereunder to one or more Eligible Transferees. No
assignment  pursuant to the immediately  preceding  sentence shall to the extent
such  assignment  represents an assignment to an  institution  other than one or
more Banks hereunder,  be in an aggregate amount less than $5,000,000 unless the
entire Commitment of the assigning Bank is so assigned.  If any Bank so sells or
assigns all or a part of its rights  hereunder or under the Notes, any reference
in this Agreement or the Notes or Letters of Credit to such assigning Bank shall
thereafter  refer to such Bank and to the  respective  assignee to the extent of
their respective interests and the respective assignee shall have, to the extent
of such assignment  (unless  otherwise  provided  therein),  the same rights and
benefits as it would if it were such assigning Bank. Each assignment pursuant to
this Section  12.04(b)  shall be effected by the assigning Bank and the assignee
Bank executing an Assignment and Assumption Agreement.  In the event of any such
assignment  (x)  to  a  commercial  bank  or  other  financial  institution  not
previously a Bank hereunder, either the assigning or the assignee Bank shall pay
to the Administrative Agent a nonrefundable assignment fee of $2,500.00, and (y)
to a Bank, either the assigning or assignee Bank shall pay to the Administrative
Agent  a  nonrefundable  assignment  fee of  $1,500.00,  and at the  time of any
assignment pursuant to this Section 12.04(b),  (i) Annex I shall be deemed to be
amended to reflect the  respective  Commitments  of the  assignee  (which  shall
result in a direct reduction to the Commitment of the assigning Bank) and of the
other Banks, and (ii) if any such assignment occurs after the Effective Date, if
requested by the assigning Bank and the assignee  Bank,  Borrower will issue new

<PAGE>

Notes to the respective  assignee and to the assigning  Bank in conformity  with
the requirements of Section 1.05 and the assigning Bank will return the canceled
Notes to the appropriate Borrower.  Each Bank and Borrower agree to execute such
documents (including,  without limitation,  amendments to this Agreement and the
other Credit Documents) as shall be necessary to effect the foregoing.  Any Bank
may at any time  pledge or assign all or any  portion  of its rights  under this
agreement  and the other loan  documents  to any Federal  Reserve  Bank  without
notice to or consent of the Borrower. No such pledge or assignment shall release
the Bank from its obligations hereunder.

            (c)  Notwithstanding  any other provisions of this Section 12.04, no
transfer or assignment of the interests or  obligations of any Bank hereunder or
any  grant  of  participation  therein  shall  be  permitted  if such  transfer,
assignment or grant would require Borrower to file a registration statement with
the SEC or to qualify the Loans under the "Blue Sky" laws of any state.

            (d) Each Bank initially party to this Agreement  hereby  represents,
and each Person that became a Bank pursuant to an  assignment  permitted by this
Section 12 will, upon its becoming party to this Agreement, represent that it is
a commercial lender, other financial  institution or other "accredited" investor
(as defined in SEC Regulation D) which makes loans in the ordinary course of its
business  and that it will  make or  acquire  Loans for its own  account  in the
ordinary course of such business, provided that subject to the preceding clauses
(a) and (b), the  disposition of any promissory  notes or other  evidences of or
interests  in  Indebtedness  held by such Bank  shall at all times be within its
exclusive control.

     12.05 No Waiver;  Remedies  Cumulative.  No failure or delay on the part of
the Administrative Agent or any Bank in exercising any right, power or privilege
hereunder  or under any other Credit  Document and no course of dealing  between
the Credit Parties and the  Administrative  Agent or any Bank shall operate as a
waiver thereof;  nor shall any single or partial exercise of any right, power or
privilege  hereunder  or under any other Credit  Document  preclude any other or
further exercise thereof or the exercise of any other right,  power or privilege
hereunder or thereunder.  The rights and remedies herein expressly  provided are
cumulative and not exclusive of any rights or remedies which the  Administrative
Agent or any Bank  would  otherwise  have.  No notice to or demand on any Credit
Party in any case shall entitle such Credit Party to any other or further notice
or demand in similar or other circumstances or constitute a waiver of the rights
of the  Administrative  Agent or the Banks to any other or further action in any
circumstances without notice or demand.

     12.06 Payments Pro Rata. (a) The Administrative  Agent agrees that promptly
after its  receipt  of each  payment  from or on behalf of any  Credit  Party in
respect of any Obligations of Borrower or any other Credit Party  hereunder,  it
shall  distribute  such  payment  to the  Banks  (other  than any Bank  that has
expressly waived its right to receive its pro rata share thereof) pro rata based
upon their respective  shares,  if any, of the Obligations with respect to which
such payment was received.

            (b) Each of the Banks agrees that,  if it should  receive any amount
hereunder  (whether by voluntary payment,  by realization upon security,  by the
exercise  of the right of setoff or  banker's  lien,  by  counterclaim  or cross

<PAGE>

action,  by  the  enforcement  of any  right  under  the  Credit  Documents,  or
otherwise)  which is  applicable to the payment of the principal of, or interest
on, the  Loans,  Unpaid  Drawings  or Fees,  of a sum which with  respect to the
related sum or sums received by other Banks is in a greater  proportion than the
total of such  Obligation  then owed and due to such Bank  bears to the total of
such  Obligation  then owed and due to all of the Banks in accordance with their
respective  Commitments  immediately  prior  to such  receipt,  then  such  Bank
receiving  such excess  payment  shall  purchase  for cash  without  recourse or
warranty from the other Banks a  participation  interest in the  Obligations  of
Borrower and any other Credit Party, respectively,  to such Banks in such amount
as  shall  result  in a  proportional  participation  by  all of  the  Banks  in
accordance with their  respective  Commitments in such amount,  provided that if
all or any portion of such excess amount is thereafter recovered from such Bank,
such purchase  shall be rescinded and the purchase  price restored to the extent
of such recovery, but without interest.

     12.07  Calculations:Computations.   (a)  The  financial  statements  to  be
furnished to the Banks pursuant  hereto shall be made and prepared in accordance
with GAAP  consistently  applied  throughout the periods involved (except as set
forth in the notes  thereto or as otherwise  disclosed in writing by Borrower to
the Banks),  provided that except as otherwise specifically provided herein, all
computations  determining  compliance with Section 8, including definitions used
therein,  shall utilize accounting principles and policies in effect at the time
of the  preparation  of,  and in  conformity  with those  used to  prepare,  the
historical  financial  statements of Borrower delivered to the Banks pursuant to
Section  6.09(b),  except as otherwise  amended or modified in  accordance  with
GAAP.

            (b) All  computations of interest  hereunder in respect of Base Rate
Loan shall be made on the basis of the actual  number of days elapsed over a 365
or 366 day year  and all  computations  of  interest  hereunder  in  respect  of
Eurodollar  Loans and computation of all fees (including  Letter of Credit Fees)
shall be made on the basis of the actual  number of days  elapsed over a 360 day
year.

JURY TRIAL . (a) THIS  AGREEMENT  AND THE OTHER CREDIT  DOCUMENTS AND THE RIGHTS
AND  OBLIGATIONS OF THE PARTIES  HEREUNDER AND THEREUNDER  SHALL BE CONSTRUED IN

Document nor any terms hereof or thereof may be changed,  waived,  discharged or
terminated  unless such change,  waiver,  discharge or termination is in writing

discharge  or  termination  shall,  without  the  consent of each Bank  affected
thereby,  (i) extend the Maturity  Date or reduce the rate or extend the time of
payment of interest (other than as a result of waiving the  applicability of any
post-default  increase  in  interest  rates)  or Fees  thereon,  or  reduce  the
principal  amount  thereof,  (ii)  increase the  Commitment of any Bank over the
amount  thereof  then in  effect  (it  being  understood  that a  waiver  of any

provision of this Section 12.12(a),  (iv) reduce the percentage specified in the
definition  of  Required  Banks,  (v) consent to the  assignment  or transfer by

termination  to any of the  provisions  of this  Agreement  as  contemplated  by
clauses (i) through (vi),  inclusive,  of the proviso to Section  12.12(a),  the
consent of the Required Banks is obtained but the consent of one or more of such
other Banks whose consent is required is not obtained,  then Borrower shall have
the  right to  replace  each such  non-consenting  Bank or Banks (so long as all
non-consenting  Banks  are so  replaced)  with  one or  more  Replacement  Banks
pursuant to Section 1.13 so long as at the time of such  replacement,  each such
Replacement  Bank  consents  to  the  proposed  change,  waiver,   discharge  or
termination;  provided that Borrower  shall not have the right to replace a Bank
solely as a result of the exercise of such Bank's rights (and the withholding of
any required consent by such Bank) pursuant to Section 12.12(a)(ii).

     12.13  Survival.  All  indemnities  set  forth  herein  including,  without
limitation,  in Section 1.10, 1.11, 2.05, 4.04, 11.06 or 12.01 shall survive the

<PAGE>

     12.15  Confidentiality.  Subject to Section 12.04, the Banks shall hold all
non-public  information  obtained pursuant to the requirements of this Agreement
in accordance with its customary procedure for handling confidential information
of this nature and in accordance  with safe and sound  banking  practices and in
any event may make disclosure reasonably required by any bona fide transferee or
participant  in  connection  with  the  contemplated  transfer  of any  Loans or
participation  therein (so long as such  transferee or participant  agrees to be
bound by the  provisions  of this Section  12.15) or as required or requested by
any governmental agency or representative  thereof or pursuant to legal process,
provided that, unless specifically  prohibited by applicable law or court order,
each Bank shall  notify  Borrower of any request by any  governmental  agency or
representative  thereof  (other  than any such  request  in  connection  with an
examination of the financial condition of such Bank by such governmental agency)
for disclosure of any such  non-public  information  prior to disclosure of such
information,  and provided  further that in no event shall any Bank be obligated
or required to return any materials furnished by Borrower,  any Guarantor or any
Subsidiary.

     12.16 Registry. Borrower hereby designate the Administrative Agent to serve
as Borrower's  agent,  solely for purposes of this Section 12.16,  to maintain a
register (the  "Register") on which it will record the Commitments  from time to
time of each of the  Banks,  the  Loans  made  by  each of the  Banks  and  each
repayment in respect of the principal amount of the Loans of each Bank.  Failure
to make any such recordation,  or any error in such recordation shall not affect
Borrower's  obligations in respect of such Loans.  With respect to any Bank, the
transfer of the Commitments of such Bank and the rights to the principal of, and
interest on, any Loan made pursuant to such  Commitments  shall not be effective
until such transfer is recorded on the Register maintained by the Administrative
Agent with respect to ownership of such  Commitments and Loans and prior to such
recordation all amounts owing to the transferor with respect to such Commitments
and Loans shall remain owing to the transferor.  The  registration of assignment
or transfer of all or part of any Commitments and Loans shall be recorded by the
Administrative   Agent  on  the  Register  only  upon  the   acceptance  by  the
Administrative  Agent  of a  properly  executed  and  delivered  Assignment  and
Assumption Agreement pursuant to Section 12.04(b).  Coincident with the delivery
of such an Assignment and Assumption  Agreement to the Administrative  Agent for
acceptance and  registration of assignment or transfer of all or part of a Loan,
or as soon  thereafter as  practicable,  the assigning or transferor  Bank shall
surrender the Note  evidencing such Loan, and thereupon one or more new Notes in
the  same  aggregate  principal  amount  shall be  issued  to the  assigning  or
transferor Bank and/or the new Bank.

     12.17 Designated Senior Indebtedness. Borrower and each of its Subsidiaries
hereby  designates  its  obligations  under this  Agreement and the other Credit
Documents as "Designated Senior Indebtedness" for purposes of, and as defined in
the Dual Indenture.

     12.18 No Futher Agreements. THIS WRITTEN AGREEMENT AND THE CREDIT DOCUMENTS
REPRESENT THE FINAL  AGREEMENT  AMONG THE PARTIES AND MAY NOT BE CONTRADICTED BY
EVIDENCE  OF  PRIOR,  CONTEMPORANEOUS,  OR  SUBSEQUENT  ORAL  AGREEMENTS  OF THE
PARTIES.
<PAGE>

     SECTION 13.  Guaranty

     13.01 The  Guaranty.  (a) In order to induce  the Banks to enter  into this
Agreement  and to extend  credit  hereunder  and in  recognition  of the  direct
benefits  to be received by Borrower  and  Guarantors  from the  proceeds of the
Loans and the  issuance of Letters of Credit,  Borrower  and  Guarantors  hereby
agree with the Banks as follows:  subject to paragraph (b) below, each Guarantor
hereby  jointly and severally,  unconditionally  and  irrevocably  guarantees as
primary  obligor and not merely as surety the full and prompt  payment when due,
whether upon  maturity,  by  acceleration  or  otherwise,  of any and all of the
Guaranteed  Obligations  of  Borrower,  and if  any  or  all  of the  Guaranteed
Obligations  of  Borrower  become  due and  payable  hereunder,  each  Guarantor
unconditionally  promises  to pay such  indebtedness  to the Banks,  on order or
demand,  together with any and all reasonable  expenses which may be incurred by
the  Administrative  Agent or the  Banks  in  collecting  any of the  Guaranteed
Obligations.

            (b) To the extent and for any period that the Dual Indenture remains
in effect,  the liability of Dual Holding Company hereunder shall never exceed a
maximum of $35,000,000 in the aggregate,  provided,  that such liability of Dual
Holding  Company  shall remain in effect  until the final  repayment of the last
$35,000,000  of the  Obligations  outstanding  and shall not be  reduced  by any
payments  (other than payments by Dual Holding  Company in  satisfaction  of the
Guaranteed Obligations) until the Obligations are reduced to a figure below that
amount.  Further,  notwithstanding the foregoing limitation,  to the extent said
Dual Indenture prohibits, limits or restricts Dual Holding Company from entering
into this Guaranty,  in whole or in part, the Agent, the Banks and the Letter of
Credit Issuer do agree that such prohibition, limitations or restrictions shall,
except as hereinbelow  specifically  stated,  take  precedence  hereover and the
obligations  of  Dual  Holding  Company  shall  be  subject  thereto,  provided,
immediately upon the lifting of such  prohibition,  limitations or restrictions,
Dual Holding Company's liability  hereunder shall be immediately  reinstated and
all  limitations  therein  shall be  eliminated  without  the need for action or
notice by, or to, any party,  provided,  notwithstanding,  the maximum aggregate
liability of Dual Holding  Company  shall  remain  $35,000,000  and shall not be
increased above said amount.  Nothing  contained in this Section  13.01(b) shall
affect the liability of any other  Guarantor or the rights of any Bank in regard
to said parties,  and shall be effective in respect of Dual Holding Company only
to the  limited  extent  and for the  period  expressly  set  forth  in the Dual
Indenture.

     13.02  Bankruptcy.   Additionally,   each  Guarantor,  subject  to  Section
13.01(b),  unconditionally and irrevocably guarantees the payment of any and all
of the  Obligations  of Borrower and each  Guarantor to the Banks whether or not
then due or  payable  by such  Persons  upon the  occurrence  in respect of such
Persons of any of the events specified in Section 9.05, and  unconditionally and
irrevocably promises to pay such Guaranteed  Obligations to the Banks, on order,
or demand, in lawful money of the United States.  The guaranty by each Guarantor
of the  payment of any and all of the  Guaranteed  Obligations  hereunder  shall
constitute a guaranty of payment, and not of collection.
<PAGE>

     13.03 Nature of  Liability.  The liability of each  Guarantor  hereunder is
exclusive  and  independent  of  any  security  for  or  other  guaranty  of the
Obligations  of such Guarantor  whether  executed by such  Guarantor,  any other
guarantor or by any other party,  and the liability of each Guarantor  hereunder
shall not be  affected or impaired by (a) any  direction  as to  application  of
payment by such Guarantor or by any other party, or (b) any other  continuing or
other  guaranty,  undertaking  or maximum  liability of such Guarantor or of any
other  party as to the  Guaranteed  Obligations  of such  Guarantor,  or (c) any
payment on or in reduction of any such other guaranty or undertaking, or (d) any
dissolution,  termination  or increase,  decrease or change in personnel by such
Guarantor,  or  (e)  any  payment  made  to  the  Administrative  Agent  on  the
indebtedness which the Administrative  Agent repays to any Guarantor pursuant to
court order in any bankruptcy, reorganization,  arrangement, moratorium or other
debtor relief proceeding, and each Guarantor waives any right to the deferral or
modification of its obligations hereunder by reason of any such proceeding.

     13.04 Independent  Obligation.  The obligations of each Guarantor hereunder
are  independent of the  obligations of any other  guarantor or Borrower,  and a
separate action or actions may be brought and prosecuted  against each Guarantor
whether or not action is brought  against any other  guarantor  or Borrower  and
whether or not any other  guarantor  or Borrower be joined in any such action or
actions.  Each Guarantor  waives,  to the fullest  extent  permitted by law, the
benefit of any statute of limitations  affecting its liability  hereunder or the
enforcement  thereof.  Any payment by any Guarantor or other  circumstance which
operates to toll any statute of limitations  as to such Guarantor  shall operate
to toll the statute of limitations as to Borrower and each Guarantor.

     13.05 Waiver of Notice,  etc.  Borrower and each  Guarantor  hereby  waives
notice of  acceptance  of this  Guaranty and notice of any liability to which it
may apply, and waives  promptness,  diligence,  presentment,  demand of payment,
protest,  notice of  dishonor or  nonpayment  of any such  liabilities,  suit or
taking of other action by the Administrative  Agent, the Letter of Credit Issuer
or any Bank,  against,  and any  other  notice  to,  any  party  liable  thereon
(including any Guarantor or Borrower).

     13.06 Authorization. Each Guarantor authorizes the Administrative Agent and
the Banks  without  notice or demand  (except as shall be required by applicable
statute  and  cannot be  waived),  and  without  affecting  or  impairing  their
liability hereunder, from time to time to:

            (a) change the manner,  place or terms of payment of,  and/or change
or extend the time of payment of, renew,  increase,  accelerate or alter, any of
the  Guaranteed  Obligations  (including any increase or decrease in the rate of
interest thereon),  any security therefor, or any liability incurred directly or
indirectly in respect  thereof,  and the Guaranty herein made shall apply to the
Guaranteed Obligations as so changed, extended, renewed or altered;
<PAGE>

            (b) exercise or refrain from exercising any rights against  Borrower
or other Persons or otherwise act or refrain from acting;

            (c) release or  substitute  any one or more  endorsers,  guarantors,
Borrower or other obligors;

            (d) settle or compromise any of the Guaranteed  Obligations,  or any
liability  (including any of those hereunder) incurred directly or indirectly in
respect  thereof or hereof,  and may  subordinate the payment of all or any part
thereof to the payment of any liability  (whether due or not) of Borrower to its
creditors other than the Banks;

            (e) apply any sums by whomsoever  paid or howsoever  realized to any
liability or liabilities  of Borrower to the Banks  regardless of what liability
or liabilities of such Guarantor or any Borrower remain unpaid;

            (f)  consent  to or waive any  breach  of, or any act,  omission  or
default under,  this Agreement or any of the instruments or agreements  referred
to herein,  or otherwise  amend,  modify or supplement  this Agreement or any of
such other instruments or agreements; and/or

            (g) take any other action which would,  under  otherwise  applicable
principles  of  common  law,  give  rise to a legal or  equitable  discharge  of
Borrower or any other Guarantor from its liabilities under this Section 13.

     13.07  Reliance.  It is not necessary for the  Administrative  Agent or the
Banks to inquire into the capacity or powers of Borrower or its  Subsidiaries or
the officers,  directors,  partners or agents acting or purporting to act on its
behalf,  and any  Guaranteed  Obligations  made or created in reliance  upon the
professed exercise of such powers shall be guaranteed hereunder.

     13.08  Subordination.  Any of the indebtedness of Borrower or any Guarantor
now or hereafter owing to each other or to any Subsidiary is hereby subordinated
to the Obligations of Borrower owing to the Administrative  Agent and the Banks;
and if the  Administrative  Agent so requests at a time when an Event of Default
exists,  all such indebtedness of Borrower or any Guarantor to such Person shall
be paid over to the  Administrative  Agent on behalf of the Banks on  account of
the Obligations,  but without affecting or impairing in any manner the liability
of such  Guarantor  under the other  provisions of this  Guaranty.  Prior to the
transfer by  Borrower  or any  Guarantor  of any note or  negotiable  instrument
evidencing  any of  such  indebtedness  such  Person  shall  mark  such  note or
negotiable   instrument  with  a  legend  that  the  same  is  subject  to  this
subordination.

     13.09  Waiver.  (a) Each  Guarantor  waives  any right  (except as shall be
required   by   applicable   statute  and  cannot  be  waived)  to  require  the
Administrative  Agent or any Bank to (i)  proceed  against  Borrower,  any other
guarantor or any other party,  (ii) proceed against or exhaust any security held

<PAGE>

from Borrower,  any other guarantor or any other party or (iii) pursue any other
remedy in the  Administrative  Agent's  or any  Bank's  power  whatsoever.  Each
Guarantor waives any defense based on or arising out of any defense of Borrower,
any other  guarantor  or any other  party,  other  than  payment  in full of the
Guaranteed  Obligations,  based on or arising out of the disability of Borrower,
any  other  guarantor  or  any  other  party,  or  the  unenforceability  of the
Guaranteed Obligations or any part thereof from any cause, or the cessation from
any  cause of the  liability  of  Borrower  other  than  payment  in full of the
Guaranteed  Obligations.  Subject to Section 13.10, the Administrative Agent may
exercise any right or remedy the Administrative  Agent may have against Borrower
without  affecting or impairing in any way the  liability of Borrower  hereunder
except to the extent the Guaranteed  Obligations have been paid. Borrower waives
any defense arising out of any such election by the Administrative Agent and the
Banks,  even though such election  operates to impair or extinguish any right of
reimbursement  or  subrogation or other right or remedy of Borrower or any other
party.
            (b) Each Guarantor waives all presentments, demands for performance,
protests and notices, including, without limitation,  notices of nonperformance,
notices of protest, notices of dishonor, notices of acceptance of this Guaranty,
and  notices  of the  existence,  creation  or  incurring  of new or  additional
Guaranteed Obligations.  Each Guarantor assumes all responsibility for being and
keeping itself informed of Borrower's financial condition and assets, and of all
other  circumstances  bearing  upon the  risk of  nonpayment  of the  Guaranteed
Obligations  and the nature,  scope and extent of the risks which each Guarantor
assumes and incurs hereunder,  and agrees that the Administrative  Agent and the
Banks shall have no duty to advise such Guarantor of  information  known to them
regarding such circumstances or risks.

     13.10  Subrogation.  No  Guarantor  will  exercise  any rights which it may
acquire by way of subrogation under this Guaranty, by any payment made hereunder
or otherwise, until all the Guaranteed Obligations shall have been paid in full.
If any amount  shall be paid to such  Guarantor  on account of such  subrogation
rights at any time when all the Guaranteed  Obligations shall not have been paid
in full,  such amount shall be  forthwith  paid to the  Administrative  Agent on
behalf  of  the  Banks  to  be  credited  and  applied  against  the  Guaranteed
Obligations.  If any Guarantor shall make payment to the Administrative Agent of
all or any part of the Guaranteed Obligations and all the Guaranteed Obligations
shall  have  been paid in full,  the  Administrative  Agent  and the Banks  will
execute and deliver to such Guarantor  appropriate  documents,  without recourse
and without representation or warranty, releasing this Guaranty and transferring
to such Guarantor any and all rights the Administrative  Agent and the Banks may
have against  Borrower or necessary to evidence the transfer by  subrogation  to
such Guarantor of any interest in the Guaranteed Obligations resulting from such
payment by such Guarantor.
