Item 1. Business

     Overview and Operating Strategy

ENSCO International  Incorporated ("ENSCO" or the "Company") is an international
offshore  contract  drilling  company that also provides  marine  transportation
services in the Gulf of Mexico.  The Company's  complement of offshore  drilling
rigs  includes  36 jackup  rigs,  ten barge rigs and eight  platform  rigs.  The
Company's  marine  transportation  fleet  consists of 37 vessels.  The Company's
operations are integral to the  exploration,  development  and production of oil
and natural gas.

Since 1987, the Company has pursued a strategy of building its fleet of offshore
drilling rigs. This strategy was exemplified by the Company's acquisition of the
remainder  of  Penrod  Holding  Corporation   ("Penrod")  in  August  1993,  the
construction  of eight new barge  rigs for the  Company's  Venezuelan  rig fleet
during 1993 and 1994 and the addition of three harsh environment  jackup rigs to
its North Sea  fleet,  two in 1994 and one in 1995.  In June 1996,  the  Company
acquired DUAL DRILLING COMPANY ("Dual") in a transaction  which added 20 rigs to
the Company's fleet. The Company  subsequently  purchased two additional  jackup
rigs, one each in November 1996 and December 1997.

With the  Company's  increasing  emphasis on offshore  markets,  the Company has
disposed  of  businesses  that  are not  offshore  oriented  or that  management
believed  would not meet the  Company's  standards  for  financial  performance.
Accordingly,  the Company sold its supply business in 1993, substantially all of
its land rigs in 1994 and its technical services business in 1995.

The Company was formed as a Texas corporation in 1975 and was  reincorporated in
Delaware in 1987.  The  Company's  principal  office is located at 2700 Fountain
Place, 1445 Ross Avenue,  Dallas, Texas,  75202-2792 and its telephone number is
(214) 922-1500.

     Acquisition of Dual Drilling

On June 12, 1996, the Company acquired Dual pursuant to an Agreement and Plan of
Merger among the Company, a wholly owned subsidiary of the Company and Dual. The
acquisition  was approved on that date by Dual  stockholders  who received 0.625
shares (1.25  shares  giving  effect to the  two-for-one  stock split  effective
September 15, 1997) of the Company's  common stock for each share of Dual common
stock. The Company issued approximately 10.1 million shares (20.1 million shares
post split) of its common  stock to Dual  stockholders  in  connection  with the
acquisition,  resulting in an acquisition price of approximately $218.4 million.
See Note 2 to the Company's Consolidated Financial Statements.

The acquired Dual operations  consisted of a fleet of 20 offshore drilling rigs,
including  ten jackup  rigs and ten  platform  rigs.  Subsequent  to the date of
acquisition, two platform rigs located off the coast of California were retired.

     Contract Drilling Operations

The Company's  contract drilling  operations are conducted by a number of wholly
owned subsidiaries (the "Subsidiaries"). The Subsidiaries engage in the drilling
of oil and gas wells in domestic and international  markets under contracts with
major  international  oil  and  gas  companies,  government  owned  oil  and gas
companies and independent oil and gas companies.  The Company  currently owns 36
jackup rigs,  ten barge rigs and seven  platform rigs. Of the 36 jackup rigs, 22
are located in the Gulf of Mexico,  seven are located in the North Sea and seven
are located in the Asia  Pacific  region.  The ten barge rigs are all located in
Venezuela and the seven platform rigs are all located in the Gulf of Mexico.  An
additional  platform rig,  which is not owned but is operated under a management
contract,  is  located  off  the  coast  of  China.  The  Company  is  currently
constructing  three  barge  rigs  for  operations  in  Venezuela  and one  harsh
environment jackup rig capable of operating worldwide. Additionally, the Company
is actively working on the design of a  semisubmersible  drilling rig to address
deeper water  drilling  locations both  domestically  and  internationally.  The
Company's  Venezuela contract drilling  operations are conducted through its 85%
ownership interest in ENSCO Drilling (Caribbean), Inc. ("Caribbean").






                                       1
<PAGE>


The Company's  contract  drilling  services and equipment are used in connection
with the process of drilling and  completing  oil and gas wells.  Demand for the
Company's  drilling  services is based upon many  factors over which the Company
has no control, including the market price of oil and gas, the stability of such
prices, the production levels and other activities of OPEC and other oil and gas
producers,  the  regional  supply and  demand for  natural  gas,  the  worldwide
expenditures for oil and gas drilling,  the level of worldwide economic activity
and the long-term effect of worldwide energy conservation measures.

The drilling services provided by the Company are conducted on a contract basis.
The Company generally  provides  drilling  services on a "daywork" basis.  Under
daywork contracts,  the Company receives a fixed amount per day for drilling the
well,  and  the  customer  bears a  major  portion  of the  ancillary  costs  of
constructing  the well. The customer may pay the cost of moving the equipment to
the job site and assembling and  dismantling the equipment.  In some cases,  the
Company provides  drilling services on a daywork contract basis along with "well
management"  services which provide  additional  incentive  compensation  to the
Company for completion of drilling activity ahead of budgeted targets set by the
customer.

During  the past  several  years,  contracts  have  typically  been  short-term,
particularly in the U.S. However, due to renewals and extension clauses included
in the  contracts,  approximately  60% of the Company's rigs have worked for the
same  customer  for greater than six months and over 48% of the  Company's  rigs
have  worked for the same  customer  for longer  than one year.  The  backlog of
business for the Subsidiaries, excluding operations conducted through Caribbean,
at  February  1,  1998  was   approximately   $330.7   million  as  compared  to
approximately $220.5 million at February 1, 1997. Approximately $20.7 million of
the  Subsidiaries  contract  backlog at  February  1, 1998 will be  realized  in
periods  subsequent  to  December  31,  1998.  Caribbean  has a  number  of term
contracts  which terminate in 1998, 1999 and 2004, with a backlog as of February
1, 1998 of  approximately  $270.6  million as compared to  approximately  $140.6
million  at  February  1, 1997.  Approximately  $215.5  million  of  Caribbean's
contract  backlog at February 1, 1998 will be realized in periods  subsequent to
December 31, 1998.

     Marine Transportation Operations

The Company conducts its marine transportation operations through a wholly owned
subsidiary,   ENSCO  Marine  Company  ("ENSCO  Marine"),   based  in  Broussard,
Louisiana.  The  Company  has  a  marine  transportation  fleet  of  37  vessels
consisting  of five  anchor  handling  tug supply  ("AHTS")  vessels,  24 supply
vessels  and  eight   mini-supply   vessels.   All  of  the   Company's   marine
transportation vessels are currently located in the Gulf of Mexico.

The  Company's five AHTS vessels  ordinarily  support  semisubmersible  drilling
rigs and large offshore construction projects or provide towing services. The 24
supply  vessels and eight  mini-supply  vessels  support  general  drilling  and
production  activity by ferrying  supplies from land and between  offshore rigs.
The Company's  vessels are typically  chartered on a well-to-well  basis,  or on
term  contracts  which may be terminated  on short notice.  At February 1, 1998,
ENSCO Marine had a backlog of contracts for its services of approximately  $39.2
million as compared to $32.3 million for such services at February 1, 1997.  The
contract backlog at February 1, 1998 that will be realized in periods subsequent
to December 31, 1998 is approximately $11.4 million.

     Major Customers

The Company  provides its services to a broad customer base which includes major
international oil and gas companies,  government owned oil and gas companies and
independent oil and gas companies.

During 1997,  aggregate  revenues  provided to the Company's  contract  drilling

     Industry Conditions and Competition

The market for offshore drilling and marine  transportation  services is largely
determined by the supply of and demand for equipment.  From the mid-1980s to the
early 1990s,  demand for offshore  drilling and marine  equipment  was generally
flat, while the over supply of offshore drilling and marine equipment  gradually
decreased,  primarily due to attrition. Between 1994 and the date hereof, demand
has steadily  improved and, as a result,  day rates and utilization for offshore
drilling and marine equipment have increased.  Technological advancements,  such
as three dimensional seismic, extended reach drilling, and multilateral drilling
techniques,  have improved the economics of finding and  developing  oil and gas
reserves.  As a result,  oil companies  have  increased  their  exploration  and
production  budgets,  which has led to increased demand for drilling and marine
transportation services. Nearly all actively marketed offshore rigs in the world
are  currently  under  contract,  and the demand for high  quality  rigs exceeds
supply in many markets.

In response to increased  demand,  several  drilling  contractors  are currently
constructing  or have announced  plans to construct new drilling  rigs,  most of
which are designed to address deep-water  applications  beyond the capability of
jackup  rigs.  The Company  believes  that unless oil and natural gas prices are
depressed for a sustained period of time, worldwide demand for offshore drilling
rigs will remain strong for the foreseeable future, and additional drilling rigs
will be needed to meet this increased demand.

The contract  drilling  business is highly  competitive  and ENSCO competes with
other drilling contractors on the basis of quality of service,  price, equipment
suitability and availability, reputation and technical expertise. Competition is
usually on a regional basis,  but drilling rigs are mobile and may be moved from
one region to another in response to demand.  Drilling  operations are generally
conducted throughout the year with some seasonal declines in winter months.

As the Company's marine transportation services are used primarily in connection
with the process of servicing offshore oil and gas operations,  demand for these
services is largely  dependent on the factors affecting the level of activity in
the offshore oil and gas industry.  ENSCO Marine  competes with numerous  vessel
operators  on the basis of quality of service,  price,  vessel  suitability  and
availability  and  reputation.  Marine  transportation  operations are conducted
throughout the year, but some reductions in vessel utilization and charter rates
may be  experienced  during winter  months due to seasonal  declines in offshore
activities.

Additional  information  regarding industry  conditions is presented in "Item 7.
Management's  Discussion  and  Analysis of  Financial  Condition  and Results of
Operations" included elsewhere herein.

      Governmental Regulation

The Company's businesses are affected by political  developments and by federal,
state,  foreign and local laws and  regulations  that relate directly to the oil
and gas  industry.  The industry is also  affected by changing  tax laws,  price
controls and other laws affecting the energy business.  The adoption of laws and
regulations  curtailing exploration and development drilling for oil and gas for
economic,  environmental or other policy reasons adversely affects the Company's
operations by limiting available drilling and other  opportunities in the energy
service industry, as well as increasing the costs of operations.

The Company and its rigs and operations are subject to federal, state, local and
foreign laws and regulations relating to engineering, design, structural, safety
and operational and inspection standards.




                                       4

Most of the Company's  marine  transportation  operations  are conducted in U.S.
waters and are subject to the coastwise laws of the United States,  principally,
the Jones Act. Such laws reserve  marine  transportation  between  points in the
United  States to vessels  built and  documented  under U.S.  laws and owned and
manned by U.S. citizens.  From time to time,  interests opposed to the Jones Act
have expressed an intent to seek changes to the Jones Act.  Although the Company
believes it is  unlikely  that the Jones Act will be  substantively  modified or
repealed,  there can be no  assurance  that the Jones Act may not be modified or
repealed.  Such changes in the Jones Act could have a material adverse effect on
the Company's operations and financial condition.

     Environmental Matters

The  Company's  operations  are  subject  to  federal,  state and local laws and
regulations  controlling  the  discharge of materials  into the  environment  or
otherwise  relating to the protection of the  environment.  Laws and regulations
specifically  applicable  to the  Company's  business  activities  could  impose
significant  liability on the Company for damages,  clean-up costs and penalties
in the event of the occurrence of oil spills or similar discharges of pollutants
into the  environment in the course of the Company's  operations,  although,  to
date,  such laws and regulations  have not had a material  adverse effect on the
Company's  results of  operations,  nor has the Company  experienced an accident
that has exposed it to material  liability for discharges of pollutants into the
environment.  In addition,  events in recent years have heightened environmental
concerns  about  the  oil  and  gas  industry  generally.  From  time  to  time,
legislative  proposals  have been  introduced  which would  materially  limit or
prohibit  offshore  drilling in certain areas. To date, no proposals which would
materially limit or prohibit offshore drilling in the Company's  principal areas
of  operation  have  been  enacted  into  law.  If laws  are  enacted  or  other
governmental  action is taken that restrict or prohibit offshore drilling in the
Company's  areas of operation or impose  environmental  protection  requirements
that  materially  increase  the cost of  offshore  exploration,  development  or
production of oil and gas, the Company could be materially adversely affected.

The United States Oil  Pollution Act of 1990 ("OPA 90") and similar  legislation
in Texas,  Louisiana and other coastal states  address oil spill  prevention and
control and significantly  expand liability  exposure across all segments of the
oil and gas industry.  OPA 90, such similar  legislation and related regulations
impose a variety of obligations on the Company  related to the prevention of oil
spills and  liability  for resulting  damages.  OPA 90 imposes  strict and, with
limited exceptions,  joint and several liability upon each responsible party for
oil removal  costs and a variety of damages.  OPA 90 imposes  ongoing  financial
responsibility  requirements.  A  failure  to comply  with OPA 90 may  subject a
responsible party to civil or criminal enforcement action.

     Operational Risks and Insurance

Contract  drilling  and oil and gas  operations  are  subject to  various  risks
including blowouts, craterings, fires and explosions, each of which could result
in damage to or  destruction  of drilling  rigs and oil and gas wells,  personal
injury and property  damage,  suspension of operations or  environmental  damage
through oil spillage or extensive,  uncontrolled  fires.  The  Company's  marine
transportation  operations are subject to various risks,  which include property
and environmental  damage and personal injury. The Company generally insures its
drilling  rigs and marine  transportation  vessels for amounts not less than the
estimated  fair market  value  thereof.  The Company  also  maintains  liability
insurance coverage in amounts and scope which management believes are comparable
to the levels of coverage  carried by other energy service  companies.  To date,
the Company has not  experienced  difficulty  in obtaining  insurance  coverage.
While the Company believes its insurance  coverages are customary for the energy
service  industry,  the  occurrence  of a  significant  event not fully  insured
against  could  have  a  material  adverse  effect  on the  Company's  financial
position.  Also,  there can be no assurance that any particular  insurance claim
will be paid or that the  Company  will be able to  procure  adequate  insurance
coverage at commercially reasonable rates in the future.

     International Operations

A  significant  portion  of  the  Company's  contract  drilling  operations  are
conducted in foreign countries.  Revenues from international operations were 41%
of  the  Company's   total  revenues  both  in  1997  and  1996.  The  Company's
international   operations  are  subject  to  political,   economic,  and  other
uncertainties,   such  as  the  risks  of   expropriation   of  its   equipment,
expropriation  of a  customer's  property or  drilling  rights,  repudiation  of
contracts,  adverse tax policies,  general hazards associated with international
sovereignty over certain areas in which the Company operates and fluctuations in
international economies.

The  Company's  international  operations  also  face  the  risk of  fluctuating
currency values and exchange  controls.  Occasionally the countries in which the
Company operates have enacted exchange controls.  Historically,  the Company has
been able to limit  these  risks by  obtaining  compensation  in  United  States
dollars  or  freely  convertible  international  currency  and,  to  the  extent
possible,  by limiting acceptance of foreign currency to amounts which match its
expenditure requirements in such currencies.

The Company currently has contract  drilling  operations in Asian countries that
have experienced substantial devaluations of their currency compared to the U.S.
dollar  over  the  last  several  months.  However,  as the  Company's  drilling
contracts  stipulate  payment in U.S.  dollars,  the Company has  experienced no
significant losses due to the devaluation of such currencies.

The Company  operates three types of drilling rigs - jackup rigs, barge rigs and
platform rigs.

The Company's drilling rigs consist of engines,  drawworks,  derricks,  pumps to
circulate  the  drilling  fluid,  blowout  preventers,  drill string and related
equipment.  The engines power a drive  mechanism that turns the drill string and
drill bit so that the hole is drilled by grinding  subsurface  materials,  which
are then carried to the surface by the drilling  fluid.  The intended well depth
and the drilling  conditions  are the principal  factors that determine the size
and type of rig most suitable for a particular drilling job.

Jackup  rigs stand on the ocean  floor with  their hull and  drilling  equipment
elevated  above the water on connected leg  supports.  Jackup rigs are generally
preferred in water depths of 350 feet or less. All of the Company's  jackup rigs
are of the  independent leg design.  The majority of the Company's  jackup units
are equipped with cantilevers, which allow the rigs to extend outward from their
hulls over fixed platforms enabling drilling of both exploratory and development
wells.  The jackup rig hull includes the drilling rig,  jacking  system,  crews'
quarters,  storage and loading  facilities,  helicopter  landing pad and related
equipment.

Barge rigs are towed to the  drilling  location and are held in place by anchors
while drilling  activities are conducted.  The Company's  barge rigs have all of
the  crews'  quarters,  storage  facilities  and  related  equipment  mounted on
floating barges, with the drilling equipment  cantilevered from the stern of the
barge.

<PAGE>

Platform  rigs  are  designed  to  be   temporarily   installed  on  permanently
constructed  offshore  platforms.  The platform rig sections are lifted onto the
offshore  platforms with the use of heavy lift cranes.  A platform rig typically
stays at a  location  for a longer  period  of time than a jackup  rig,  because
several wells can be drilled from a single offshore platform.

The  Company  is  currently  constructing  three  barge rigs for  operations  in
Venezuela  and a harsh  environment  jackup rig capable of operating  worldwide.
Additionally, the Company is actively working on the design of a semisubmersible
drilling rig to address deeper water drilling  locations both  domestically  and
internationally.

Over the life of a typical rig, several of the major components are replaced due
to normal wear and tear. All of the Company's rigs are in good condition.


     Marine Transportation

The Company has a marine  transportation  fleet of 37 vessels consisting of five
anchor  handling tug supply  vessels,  24 supply  vessels and eight  mini-supply
vessels.  All of the  Company's  marine  transportation  vessels  are  currently
located  in the  Gulf  of  Mexico.  Substantially  all of the  Company's  marine
transportation  vessels, which had a combined net book value of $39.5 million at
December 31, 1997,  are pledged as collateral to secure  payment of secured term
loans with an outstanding balance of $13.7 million at December 31, 1997.

The  following  table  provides,  as of  February 1, 1998,  certain  information

Item 7.    Management's Discussion and Analysis of Financial Condition and
Results of Operations

Business Environment

       ENSCO International Incorporated ("ENSCO" or the "Company") 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  concentrated  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.

       Worldwide  drilling  activity  remained  strong  in 1997,  with  industry
publications  indicating exploration and production spending increases in excess
of 10% for the second  consecutive  year.  Demand  for  offshore  drilling  rigs
exceeded  supply  in many  markets,  pushing  day  rates  higher.  Technological
advancements  have  played a major  role in  reducing  the cost of  finding  and
developing  reserves,  thereby  contributing to the demand for offshore drilling
rigs.  In  response  to  increased  demand,  several  drilling  contractors  are
currently  constructing  or have announced plans to construct new drilling rigs,
most of which  are  designed  to  address  deep-water  applications  beyond  the
capability of jackup rigs. The Company  believes that unless oil and natural gas
prices  are  depressed  for a  sustained  period of time,  worldwide  demand for
offshore  drilling  rigs will  remain  strong for the  foreseeable  future,  and
additional drilling rigs will be needed to meet this increased demand.

Results of Operations

       The Company achieved another  successive  year of record results in 1997.
Compared to 1996,  revenues  increased 74% to $815.1 million,  operating  income
increased  162% to  $389.3  million  and net  income  increased  145% to  $233.9
million.  The improved results reflect the contribution  from the acquisition of
DUAL DRILLING COMPANY ("Dual") in June 1996 and the sustained increase in demand
for offshore drilling rigs and marine  transportation  equipment which propelled
day rates and utilization to higher levels in 1997.

       In 1996, revenues  increased  68% to  $468.8  million,  operating  income
increased 169% to $148.7  million and net income  increased 98% to $95.4 million
as compared to 1995.  These  improvements  are the result of increased day rates
and  utilization and the added  contribution  from the Dual  acquisition.  ENSCO
acquired  Dual  in a  purchase  acquisition  on June  12,  1996.  The  Company's
consolidated   financial  statements  include  the  results  of  Dual  from  the
acquisition  date.  The  acquired  Dual  operations  consisted  of a fleet of 20
offshore drilling rigs,  including ten jackup rigs and ten platform rigs. Two of
the platform rigs were retired in 1996 and another platform rig, located off the
coast of China, is managed, but not owned, by the Company.

      Discussions  relative  to each of the  Company's  operating  segments  and
geographic operations are set forth below.

      Contract  Drilling.  The Company's  contract  drilling  segment  currently
consists  of 36  jackup  rigs,  ten  barge  rigs and eight  platform  rigs.  The
following is an analysis of the geographic  locations of the Company's  offshore
drilling rigs at December 31, 1997, 1996 and 1995.

                                                          1997     1996     1995

                                                          ====     ====     ====


    (1)   Includes  one  jackup rig  operated  by the  Company  that was
          previously 49% owned.  The Company  acquired the remaining 51%
          interest in May 1997.
    (2)   Seven are located in the Gulf of Mexico and one,  which is not
          owned but is operated under a management contract,  is located
          off the coast of China.

     The  Company's  North  America  jackup  and  platform  rigs  operate  under
relatively  short-term agreements with contract durations normally not exceeding
six months.  Four of the Company's  seven Europe jackup rigs are committed under
contract to a joint venture of major oil and gas  exploration  companies and are
expected  to  continue  to work under these  contracts  at least  through  1999,
however,  the joint venture may terminate any of the contracts  with six month's
notice. The Company's Asia Pacific jackup rigs generally operate under contracts
with one to two year terms.  The Company's  ten barge rigs in Venezuela  operate
under  long-term   contracts  for  Petroleos  de  Venezuela,   S.A.   ("PDVSA"),
Venezuela's national oil company, that expire in 1998 and 1999. The contracts on
the barge rigs afford  PDVSA the option to buy each of the rigs during or at the
end of the  contracts.  The Company is  currently in  discussions  with PDVSA to
extend the four contracts  expiring in 1998. The Company currently believes that
it will be able to secure  new  contracts  with  PDVSA or  another  operator  in
Venezuela at rates similar to those currently  being received.  If PDVSA were to
exercise their option to purchase any of the rigs, the Company would recognize a
gain on the sale.

     In 1997,  revenues  from the contract  drilling  segment  increased  $312.3
million,  or 76%, and operating margin  increased $241.6 million,  or 115%, from
1996. The increase in revenues and operating margin is primarily attributable to
an increase in average day rates,  which increased 52% for the contract drilling
segment overall. In addition,  revenues increased approximately $90.7 million as
a  result  of a full  year  of  operations  of the  rigs  acquired  in the  Dual
acquisition and other rig acquisitions in 1996 and 1997. The Company's  contract
drilling  operating  margin was negatively  impacted by an increase in operating
expenses  of $70.7  million in 1997 as  compared  to 1996.  Approximately  $41.3
million, or 58%, of the increase in operating expenses resulted from a full year
of  operations  of the rigs  acquired  in the Dual  acquisition  and  other  rig
acquisitions in 1996 and 1997. The remaining  increase in operating  expenses is
primarily  due to higher  wages,  benefits and  training  costs for offshore rig
workers and increased oilfield equipment and materials costs. In general, as the
demand for  offshore  drilling  services  has  increased,  so has the demand for
qualified  personnel and oilfield supply  equipment which are fundamental to the
Company's operations, therefore, resulting in cost increases. The Company places
significant  importance on managing its  operations  efficiently to minimize the
effects of these cost increases.

     In 1996,  revenues  from the contract  drilling  segment  increased  $167.8
million,  or 70%, and operating margin  increased  $101.5 million,  or 94%, from
1995. The increase in revenues and operating margin is primarily attributable to
a 22%  increase in average day rates and an increase in  utilization,  to 90% in
1996 from 86% in 1995.  In  addition,  revenues  increased  approximately  $70.7
million  as a result of the rigs  acquired  in the Dual  acquisition.  Operating
expenses in 1996 increased  $66.3 million over 1995 levels,  with $41.5 million,
or 63%, of this  increase  being  attributable  to the rigs acquired in the Dual
acquisition.  Additionally,  1996 operating  expenses increased over 1995 levels
due  primarily  to a four  percent  increase in  utilization,  higher  wages and
benefits and increased oilfield equipment and materials costs.


                                       15

    North America Jackup Rigs

      In 1997,  revenues for North America jackup rigs increased $160.7 million,
or 81%, and operating margin  increased $134.4 million,  or 126%, as compared to
1996. The increase in revenues and operating margin is primarily attributable to
a 67% increase in average day rates in 1997,  and an increase in  utilization to
96% in 1997 from 93% in 1996. In addition,  the 1997 results  benefitted  from a
full  year of  operations  from  the  rigs  acquired  in the  Dual  acquisition,
contributing  an  additional  $28.0  million in  revenues  and $18.2  million in
operating margin from the prior year results.

      In 1996,  revenues  increased $77.9 million,  or 65%, and operating margin
increased  $60.0  million,  or 129%, as compared to 1995.  These  increases were
primarily due to an increase in average day rates of approximately  35% from the
prior year.  In addition,  the North  America  jackup rigs  acquired in the Dual
acquisition contributed $26.7 million in revenues and $15.7 million in operating
margin in 1996, representing 34% and 26% of the respective increases.

    Europe Jackup Rigs

      In 1997,  revenues for Europe jackup rigs increased $82.0 million, or 89%,
and operating margin increased $77.4 million,  or 192%, as compared to 1996. The
increase in revenues and  operating  margin is  primarily  due to an increase in
average day rates of 67% in 1997, and an increase in utilization to 100% in 1997
from 88% in  1996.  Three of the  Europe  jackup  rigs  were in a  shipyard  for
modifications   and  enhancements   during  part  of  1996  resulting  in  lower
utilization. In December 1997, the Company acquired a harsh environment, Gorilla
class,  jackup rig currently  located in the Norwegian  sector of the North Sea.
The Company will bareboat charter the rig to Smedvig asa, the seller of the rig,
which charter the Company expects will last until the year 2000.

      In 1996, revenues increased by $32.3 million, or 54%, and operating margin
increased by $17.2 million,  or 74%, as compared to 1995.  These  increases were
primarily due to an increase in utilization to 88% in 1996 from 73% in 1995, and
a 12% increase in average day rates.  Two of the  Company's  Europe  jackup rigs
were off contract undergoing  modifications and enhancements for the majority of
1995 and an additional  jackup rig,  acquired in March 1995,  was operated under
bareboat charter for all of 1995.

    Asia Pacific Jackup Rigs

      The Company's Asia Pacific  jackup rigs are deployed in various  locations
throughout  Southeast  Asia,  the Middle East and  Australia.  Prior to the Dual
acquisition  in June 1996,  the Company had no  operations  in the Asia  Pacific
region. Consequently,  the increase in revenues and operating margin in 1997, as
compared to 1996, is  significantly  enhanced as a result of the partial year of
operations in 1996. Additionally,  the Company purchased a jackup rig located in
Southeast Asia in November 1996,  relocated  another jackup rig from the Gulf of
Mexico to  Southeast  Asia in the  first  quarter  of 1997,  and  purchased  the
remaining 51% interest in a jointly-owned jackup rig in May 1997.

      In 1997,  revenues  for the  Asia  Pacific  jackup  rigs  increased  $56.2
million,  or 236%, and operating margin  increased $28.3 million,  or 358%, from
1996. Average day rates increased 47% in 1997 while utilization decreased to 79%
in 1997 from 86% in 1996. The decrease in utilization in 1997 is due to shipyard
downtime.  During 1997,  all of the Asia Pacific jackup rigs were in a shipyard,
or mobilizing  to a shipyard,  for a portion of the year for  modifications  and
enhancements.  Two of the Asia Pacific jackup rigs that were previously  working
off the coast of India entered the shipyard in late 1997 for  modifications  and
enhancements and are expected to return to service by the middle of 1998.

    South America Barge Rigs

      In 1997,  revenues increased $7.3 million,  or 10%, while operating margin
remained  flat as compared to 1996.  The lack of increase in  operating  margin,
despite the  increase in  revenues,  is  primarily  due to the  structure of the
Company's contracts with PDVSA. Under these contracts, the Company is reimbursed
through its day rate for  inflationary  cost increases in Venezuela,  therefore,
the increase in revenues effectively  reimburses the Company for cost increases.
Certain of these contracts expire in 1998 and 1999 as discussed above.


                                       16
<PAGE>


     In 1996,  revenues  increased $13.5 million,  or 22%, and operating  margin
increased  $10.0 million,  or 26%, as compared to 1995. The increase in revenues
and operating  margin is primarily due to an increase in utilization,  to 91% in
1996 from 86% in 1995, and an increase in average day rates of approximately 15%
from the prior year.  The  increase in  utilization  primarily  results from the
return to work of two barge  rigs,  the ENSCO V and VI, in May and July of 1996,
after being in the shipyard for  modifications and enhancements for the majority
of 1995. The increase in day rates,  revenues and operating margin was partially
attributable  to the receipt of  retroactive  inflationary  cost  increases that
related to prior periods.

      Marine  Transportation.  The Company currently has a marine transportation
fleet of 37 vessels,  consisting of five anchor handling tug supply vessels,  24
supply  vessels  and eight  mini-supply  vessels.  All of the  Company's  marine
transportation vessels are located in the Gulf of Mexico. Contract durations for
the  Company's  marine  transportation  vessels are  relatively  short-term  and
normally do not exceed six months.

      In  1997,  revenues  for  the  Company's  marine  transportation   segment
increased $34.0 million,  or 56%, and operating  margin increased $25.3 million,
or 80%, as compared to 1996.  The increase in revenues and  operating  margin is
due to an approximate  $2,700, or 53%, increase in average day rates in 1997 and
an increase in utilization to 91% in 1997 from 89% in 1996.

     Revenues  and  operating  margin for the  Company's  marine  transportation
segment  increased  $21.9  million,   or  57%,  and  $16.8  million,   or  113%,
respectively,   in  1996  as  compared  to  1995,  due  primarily  to  increased
utilization and day rates for the Company's supply vessels.

      Depreciation  and  Amortization.  In 1997,  depreciation  and amortization
expense  increased  $23.0 million,  or 28%, as compared to 1996. The increase in
depreciation  and  amortization  is primarily due to a full year of depreciation
and goodwill  amortization  on the assets acquired in the Dual  acquisition,  as
well as additional  depreciation from other asset acquisitions and modifications
and  enhancements to existing  assets.  In 1996,  depreciation  and amortization
expense  increased  by  $23.4  million,  or 40%,  from  1995  due  primarily  to
depreciation and amortization associated with the Dual acquisition, depreciation
associated with major modifications and enhancements to various rigs and vessels
and depreciation on six supply vessels purchased in late 1995.

      The Company recently completed economic and engineering evaluations of its
drilling  rigs and marine  vessels and  concluded  that the useful  lives of its
drilling rigs and marine vessels should be extended in order to provide a better
matching of revenues and depreciation  expense over the economic useful lives of
the assets.  As a result,  effective  January 1, 1998,  the useful  lives of the
Company's  drilling  rigs and  marine  vessels  will be  extended,  on  average,
approximately  five  years,  which  will  result  in lower  annual  depreciation
expense.

     General and  Administrative.  General  and  administrative  expenses,  as a
percentage  of  revenues,  were 1.8%,  2.3% and 3.4% for the three  years  ended
December  31,  1997,  1996  and  1995,   respectively.   In  1997,  general  and
administrative expenses increased $3.3 million, or 30%, as compared to 1996, due
primarily  to a full  year of  expense  for the  additional  personnel  added in
conjunction with the Dual acquisition and higher  performance based compensation
and benefits costs. In 1996, general and administrative  expenses increased $1.4
million,  or 15%, as compared to 1995,  due  primarily to  additional  personnel
added in the Dual acquisition and increased  performance based  compensation and
benefits costs.

     Other Income (Expense).  Other income (expense) for each of the three years
in the period ended December 31, 1997 is as follows (in millions):

                                            1997          1996           1995

      Other, net ......................        .5          10.3            2.4
                                           ------        ------         ------
                                           $(13.5)       $ (6.0)        $ (7.9)
                                           ======        ======         ======

      Other  expense  increased  in 1997 as  compared to 1996 due  primarily  to
non-recurring  income items recorded in "Other, net" in 1996 offset, in part, by
additional  interest  income from higher  outstanding  cash  balances.  The 1996
non-recurring  income items  include a $6.4  million  litigation  settlement  as


                                       17
<PAGE>


discussed in Note 8 to the  Consolidated  Financial  Statements and $2.9 million
from the  disposition  of  securities  previously  received from the sale of the
Company's  technical  services  operations  as  discussed  in  Note  12  to  the
Consolidated  Financial Statements.  Other expense decreased in 1996 as compared
to 1995, due primarily to the non-recurring income items discussed above offset,
in part, by an increase in net interest expense due primarily to additional debt
assumed in the Dual acquisition.

      Provision for Income Taxes.  For the years ended  December 31, 1997,  1996
and 1995 the Company  recorded  provisions  for income taxes of $137.8  million,
$44.0 million and $3.4 million, resulting in effective tax rates of 36.7%, 30.8%
and 7.2%,  respectively.  The  Company's  provision  for income taxes  increased
significantly  in 1997  as  compared  to 1996  due  primarily  to the  increased
profitability of the Company and the recognition,  in 1996, of the remaining net
operating losses for financial reporting purposes. The increase in the provision
for income taxes in 1996 as compared to 1995 is due  primarily to the  increased
profitability of the Company and the release of a larger amount of the valuation
allowance on the Company's net operating losses in 1995. The Company's effective
tax  rate  varies  between  years  due  primarily  to  the  Company's  level  of
profitability, the expected utilization or non-utilization of U.S. net operating
loss  carryforwards and foreign taxes. See Note 7 to the Company's  Consolidated
Financial Statements.

      Income from  Discontinued  Operations.  Effective  September 30, 1995, the
Company exited the technical services business through the sale of substantially
all of the assets of its wholly owned subsidiary,  ENSCO Technology Company, for
total  consideration  of $19.8  million,  including  liabilities of $1.9 million
assumed  by the  purchaser.  As a  result  of this  transaction,  the  Company's
financial  statements  were  reclassified  to present  the  Company's  technical
services segment as a discontinued  operation.  Included in the 1995 Income from
Discontinued Operations is a gain on the sale of the technical services business
of $5.2 million and income from  operations of the technical  services  business
for the nine months  ended  September  30,  1995.  Revenues  from the  technical
services  operations  were $13.4  million in 1995.  See Note 12 to the Company's
Consolidated Financial Statements.

                                                      =======   =======  =======

      In 1997, cash flow from operations  increased  $138.0 million,  or 69%, as
compared to 1996. The 1997 increase in cash flow from  operations is primarily a
result of improved  operating  results offset, in part, by cash used for working
capital changes. In 1996, cash flow from operations increased $114.0 million, or
135%, as compared to 1995, due primarily to improved operating results.

      As part of the Company's ongoing enhancement program, approximately $341.0
million has been invested over the last three years in upgrading the  capability
and  extending  the  service  lives of the  Company's  drilling  rigs and marine
vessels.  In  addition,  the  Company  has added to its fleet of  drilling  rigs
through   acquisitions.   In  December  1997,  the  Company   acquired  a  harsh
environment,  Gorilla  class,  jackup rig  located in the North Sea and,  in May
1997, purchased the remaining 51% interest of a previously  jointly-owned jackup
rig  located in  Southeast  Asia.  In 1996,  the  Company  acquired a jackup rig
located in Southeast Asia and made the final payment on a jackup rig,  purchased
in 1995, which is located in the North Sea. Not included in the cash expenditure
amounts above is the 10.1 million  shares (20.1 million  shares giving effect to
the  two-for-one  stock split  effective  September  15, 1997) of common  stock,
valued at $218.4 million, issued in the acquisition of Dual.

      The Company  recently  announced the  construction of three new barge rigs
for Lake  Maracaibo,  Venezuela,  which are tied to five-year  contracts with an
affiliate of Chevron  Corporation.  The drilling rigs will be  constructed at an


                                       18
<PAGE>

estimated  aggregate cost of $105.0 million and are projected to be delivered in
early 1999.  The Company  also  recently  announced  the  construction  of a new
international class harsh environment jackup rig. The rig, an enhanced KFELS MOD
V, is scheduled  for  delivery by January 2000 at a total cost of  approximately
$130.0 million.

     Management  anticipates  that capital  expenditures  will be  approximately
$40.0 to $50.0 million for existing  operations and $150.0 to $200.0 million for
upgrades  and  enhancements  in 1998.  In addition,  the Company  plans to spend
approximately $150.0 million in 1998 for the new construction projects discussed
above.  The Company may spend  additional  funds to construct or acquire rigs or
vessels in 1998 depending on market conditions and opportunities.

     Financing  and Capital  Resources.  The  Company's  long-term  debt,  total
capital and debt to capital  ratios are  summarized  below (in millions,  except
percentages):

                                                        At December 31,
                                               ---------------------------------
                                                  1997         1996       1995
                                               --------     --------     -------
      Long-term debt .......................   $  400.8     $  258.6     $ 159.2
      Total capital ........................    1,477.5      1,104.5       690.4
      Long-term debt to total capital ......      27.1%        23.4%       23.1%

     The increase in long-term debt in 1997 as compared to 1996 is primarily due
to the issuance of $300.0  million of unsecured  debt in a November  1997 public
debt offering.  The debt offering consisted of $150.0 million of 6.75% Notes due
November  15, 2007 (the  "Notes")  and $150.0  million of 7.20%  Debentures  due
November 15, 2027 (the  "Debentures").  The Notes and the Debentures were issued
pursuant to a $500.0 million universal shelf  registration  statement filed with
the  Securities  and Exchange  Commission in October 1997. The net proceeds from
the offering totaled approximately $287.8 million after selling and underwriting
discounts  and the  settlement  of interest  rate  hedges.  Approximately  $75.0
million of the net proceeds were used to retire the Company's  revolving  credit
facility  and $103.2  million of the net  proceeds  were used to acquire a harsh
environment,  Gorilla class,  jackup rig. The Company  recorded an extraordinary
charge in the fourth quarter of 1997 for $1.0 million,  net of income taxes,  to
write-off the remaining  deferred  financing costs associated with the revolving
credit  facility.  The  increase in  long-term  debt in 1996 as compared to 1995
primarily  relates to $129.0 million of debt assumed in the  acquisition of Dual
offset,  in part, by scheduled  repayments of existing  debt.  See Note 4 to the
Company's Consolidated Financial Statements.

     The total capital of the Company  increased in 1997 as compared to 1996 due
to the  profitability of the Company in 1997 and the increase in long-term debt.
Total  capital  increased  in 1996 as compared  to 1995,  due  primarily  to the
issuance of shares of the Company's  common stock in the Dual  acquisition,  the
net increase in long-term debt and the profitability of the Company in 1996.

     The  Company's  liquidity  position  is  summarized  in the table below (in
millions, except ratios):

                                                          At December 31,
                                                  ------------------------------
                                                   1997         1996       1995
                                                  ------       ------    -------

       Cash and short-term investments .....      $262.2      $  80.7    $  82.1
       Working capital .....................       316.2        107.5       78.9
       Current ratio .......................         3.4          2.0        1.9

     Based  on  the  current  financial  condition  of the  Company,  management
believes cash flow from  operations and the Company's  working capital should be
sufficient to fund the Company's  ongoing  liquidity  needs for the  foreseeable
future. The Company may also obtain a new unsecured  revolving line of credit to
supplement its existing cash flow for capital  spending  projects.  In addition,
the Company has the  ability to issue up to $200.0  million in debt  securities,
preferred stock or common stock under the shelf registration  statement filed in
October 1997.

Year 2000 Issue

       The  Company  has  developed  a task force that is  currently  working to
ascertain and resolve the potential  problems  associated with the Year 2000 and
the processing of date sensitive information by the Company's computer and other
systems. Based on preliminary information,  the Company believes that it will be
able to implement  successfully the systems and programming changes necessary to
address the Year 2000  issues,  and does not expect the cost of such  changes to
have  a  material  impact  on  the  Company's  financial  position,  results  of
operations or cash flows in future periods.

Market Risk

       The Company occasionally uses financial  instruments to hedge against its
exposure to changes in foreign  currencies and interest rates.  The Company does
not use financial  instruments for trading purposes.  The Company  predominantly
structures   its  contracts  in  U.S.   dollars  to  mitigate  its  exposure  to
fluctuations  in foreign  currencies.  The Company will,  however,  from time to
time, hedge its known liabilities in foreign  currencies to reduce the impact of
foreign currency gains and losses in its financial results.  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. See Note 11 to the  Consolidated  Financial
Statements.

Outlook and Forward-Looking Statements

     The Company believes the demand for offshore drilling equipment will remain
strong through 1998.  Published estimates of exploration and production spending
by oil and gas companies in 1998 indicate  projected  increases of approximately
10% over 1997 spending levels. Although the Company believes that demand for its
equipment  should remain  strong,  factors  beyond the  Company's  control could
adversely affect future market  conditions.  Such factors  include,  but are not
limited  to, a decline in the rate of  worldwide  economic  growth  leading to a
reduction in demand for energy,  and  depressed oil and natural gas prices for a
sustained  period of time resulting in deferrals or cutbacks in exploration  and
production spending.

      In  response  to  the current  and  anticipated  increase  in demand,  the
Company is currently constructing three new barge rigs for Venezuela and one new
harsh environment  jackup rig. The Company also has an option,  which expires in
the third  quarter of 1998, to build a second harsh  environment  jackup rig. In
addition to new  construction,  the Company  currently  intends to perform major
upgrades  to five of its  jackup  rigs in 1998.  Additionally,  the  Company  is
actively  working  on the  design  of a  semisubmersible  drilling  rig that the
Company  intends to market to oil companies for deeper water drilling  locations
both domestically and internationally.

       This  report  contains   forward-looking   statements  based  on  current
expectations  that  involve  a number  of risks  and  uncertainties.  Generally,
forward-looking   statements  include  words  or  phrases  such  as  "management
anticipates,"  "the Company  believes," "the Company  anticipates," "the Company
expects"  and words and  phrases  of similar  impact,  and  include  but are not
limited to statements regarding future operations and business environment.  The
forward-looking  statements  are made pursuant to safe harbor  provisions of the
Private  Securities  Litigation Reform Act of 1995. The factors that could cause
actual results to differ materially from those in the forward-looking statements
include the following:  (i) industry  conditions and competition,  (ii) cyclical
nature of the industry,  (iii) worldwide  expenditures for oil and gas drilling,
(iv)  operational  risks and insurance,  (v) risks  associated with operating in
foreign  jurisdictions,  (vi)  environmental  liabilities which may arise in the
future  which are not covered by  insurance  or  indemnity,  (vii) the impact of
current  and  future  laws  and  government  regulation,  as well as  repeal  or
modification  of same,  affecting  the oil and gas  industry  and the  Company's
operations in particular,  and (viii) the risks described elsewhere,  herein and
from time to time in the Company's  other reports to the Securities and Exchange
Commission.

Item 8. Financial Statements and Supplementary Data

                              REPORT OF MANAGEMENT

       The management of ENSCO  International  Incorporated and its subsidiaries
has  responsibility  for  the  preparation,  integrity  and  reliability  of the
consolidated financial statements and related financial information contained in
this report.

       The consolidated  financial  statements included in this report have been
prepared  in  conformity  with  generally  accepted  accounting  principles  and
prevailing  practices of the industries in which the Company  operates.  In some
instances,  these  financial  statements  include  amounts  that  are  based  on
management's best estimates and judgments.

       The Company  maintains a system of procedures and controls over financial
reporting  that is designed to provide  reasonable  assurance  to the  Company's
management  and Board of  Directors  regarding  the  integrity  and the fair and
reliable  preparation  and  presentation,  in  all  material  respects,  of  its
published financial statements. This system of financial controls and procedures
is reviewed,  modified, and improved as changes occur in business conditions and
operations,  and as a result of suggestions  from the  independent  accountants.
There are inherent  limitations in the  effectiveness  of any system of internal
control  and even an  effective  system of internal  control  can  provide  only
reasonable assurance with respect to the financial statement preparation and may
vary over time. Management believes that, as of December 31, 1997, the Company's
internal  control system provides  reasonable  assurance that material errors or
irregularities  will be prevented or detected within a timely period and is cost
effective.

       As part of  management's  responsibility  for monitoring  compliance with
established  policies and  procedures,  it relies on, among other things,  audit
procedures  performed by corporate auditors and independent  accountants to give
assurance that  established  policies and procedures are adhered to in all areas
subject to their  audits.  The Board of Directors,  operating  through its Audit
Committee  composed  solely  of  outside  directors,   meets  periodically  with
management and the independent  accountants for the purpose of monitoring  their
activities to ensure that each is properly discharging its responsibilities. The
Audit  Committee and independent  accountants  have  unrestricted  access to one
another to discuss their findings.



                        REPORT OF INDEPENDENT ACCOUNTANTS

To the Board of Directors and Stockholders of ENSCO International Incorporated

In our opinion,  the  accompanying  consolidated  balance  sheet and the related
consolidated  statements  of income and of cash  flows  present  fairly,  in all
material respects,  the financial position of ENSCO  International  Incorporated
and its  subsidiaries  at December  31, 1997 and 1996,  and the results of their
operations  and their cash flows for each of the three years in the period ended
December 31, 1997, in conformity with generally accepted accounting  principles.
These financial  statements are the responsibility of the Company's  management;
our responsibility is to express an opinion on these financial  statements based
on our audits.  We conducted our audits of these  statements in accordance  with
generally accepted auditing standards which require that we plan and perform the
audit to obtain reasonable  assurance about whether the financial statements are
free of material  misstatement.  An audit includes  examining,  on a test basis,
evidence  supporting the amounts and  disclosures  in the financial  statements,
assessing the  accounting  principles  used and  significant  estimates  made by
management,  and evaluating the overall  financial  statement  presentation.  We
believe  that our audits  provide a reasonable  basis for the opinion  expressed
above.

Company's  offshore fleet consists of 22 jackup rigs, seven platform rigs and 37
oilfield  support  vessels,  all  located in the Gulf of Mexico.  The  Company's
European  operations  consist of seven  jackup  rigs  currently  deployed in the
United Kingdom, Dutch, and Norwegian sectors of the North Sea. In South America,
the Company's  fleet  consists of ten barge rigs located in  Venezuela.  In Asia
Pacific,  the fleet consists of seven jackup rigs deployed in various  locations
and one platform rig that is not owned,  but is operated by the Company  under a
management  contract.  All of the Company's  domestic and foreign operations are
conducted through wholly owned subsidiaries, with the exception of the Company's
Venezuelan  operations  in which the Company holds an 85% interest and a locally
owned private company owns the remaining 15%.

        The Company's  operations are integral to the  exploration,  development
and  production  of oil  and  gas.  Business  levels  for the  Company,  and its
corresponding   operating  results,  are  significantly  affected  by  worldwide
expenditures for oil and gas drilling,  particularly in the Gulf of Mexico where
the Company has a large concentration of its rigs and vessels.  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.

    Principles of Consolidation

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

    Pervasiveness of Estimates

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

    Cash Equivalents

         The  Company  considers  all  highly  liquid  investments  to  be  cash
equivalents  if they  have  maturities  of three  months  or less at the date of
purchase.

    Foreign Currency Translation

         The U.S.  dollar is the  functional  currency  of all of the  Company's
foreign  subsidiaries.  The  financial  statements of foreign  subsidiaries  are
remeasured in U.S. dollars based on a combination of both current and historical
exchange rates. Gains and losses caused by the remeasurement  process applicable
to foreign  subsidiaries are reflected in the consolidated  statement of income.
Translation gains and losses were  insignificant for all years in the three year
period ended  December 31, 1997.  In prior years,  the  financial  statements of
certain  foreign  subsidiaries  were  maintained in the local foreign  currency.
Foreign currency translation adjustments for those subsidiaries were accumulated
as a separate component of equity.

    Property and Equipment

         Depreciation on drilling rigs and related  equipment and marine vessels
acquired  after 1990 is computed  using the straight line method over  estimated
useful lives ranging from 4 to 19 years.  Depreciation  for other  equipment and
for buildings and  improvements  is computed using the straight line method over
estimated  useful  lives  ranging  from  2  to  6  years  and  2  to  30  years,
respectively.  Depreciation  on drilling  rigs and related  equipment and marine
vessels acquired prior to 1991 is computed using the units-of-production  method
over   estimated   useful  lives  ranging  from  10  to  15  years.   Under  the
units-of-production  method,  depreciation  is based on the  utilization  of the
drilling rigs and vessels with a minimum  provision when the rigs or vessels are
idle.

         Maintenance and repair costs are charged to expense as incurred.  Major
renewals and  improvements  are  capitalized.  Upon retirement or replacement of
assets,  the related  cost and  accumulated  depreciation  are removed  from the
accounts and the resulting gain or loss is included in income.

    Goodwill

         Goodwill  arising from  acquisitions is amortized on the  straight-line
basis over  periods  ranging from 10 to 40 years.  Amortization  of goodwill was
$3.1  million,  $1.7 million and $0.5  million for the years ended  December 31,
1997, 1996 and 1995,  respectively.  Goodwill, net of accumulated  amortization,
was  $116.7   million  and  $106.2  million  at  December  31,  1997  and  1996,
respectively,  and is included in Other Assets, Net. Accumulated amortization of
goodwill  at  December  31,  1997 and 1996 was $7.3  million  and $4.2  million,
respectively. On a periodic basis, the Company estimates the undiscounted future
cash flows to be generated by the assets  acquired to ensure the carrying  value
of goodwill has not been impaired.

    Impairment of Assets

         The Company  evaluates  the carrying  value of its  long-lived  assets,
consisting  primarily of property and  equipment  and  goodwill,  when events or
changes in circumstances  indicate that the carrying value of such assets may be
impaired.  The  determination  of  impairment  is  based  upon  expectations  of
undiscounted future cash flows, before interest, of the related asset.

    Revenue Recognition

         The Company's drilling and marine services contracts  generally provide
for payment on a day rate basis,  and  revenues  are  recognized  as the work is
performed.

    Income Taxes

         Deferred tax assets and  liabilities are recognized for the anticipated
future tax effects of  temporary  differences  between the  financial  statement
basis  and the tax  basis of the  Company's  assets  and  liabilities  using the
enacted tax rates in effect at year end. A valuation  allowance for deferred tax
assets is recorded  when it is more  likely  than not that the benefit  from the
deferred tax asset will not be realized.

    Minority Interest

         The  Company's  Venezuelan   operations  are  conducted  through  ENSCO
Drilling  (Caribbean),  Inc.  ("Caribbean"),  in which the  Company  owns an 85%
equity  interest.  Minority  interest  expense for the three years in the period
ended December 31, 1997 reflects the minority  shareholder's 15% equity interest
in Caribbean.  The minority shareholder is also entitled to an additional 15% of
the net proceeds from any future sale of rigs currently owned by Caribbean.

    Stock-Based Employee Compensation

         The  Company  adopted  Statement  of  Financial   Accounting  Standards
("SFAS") No. 123, "Accounting for Stock-Based  Compensation," in 1996. Under the
provisions  of SFAS No. 123,  the  Company  has  elected to  continue  using the
intrinsic  value method of accounting for employee  stock-based  compensation in
accordance  with  Accounting  Principles  Board Opinion No. 25,  "Accounting for
Stock Issued to Employees."  Under the intrinsic  value method,  if the exercise
price of the Company's  stock options  equals the market value of the underlying
stock on the date of grant,  no compensation  expense is recognized.  See Note 6
"Employee  Benefit Plans" for the required  disclosure of pro forma  information
regarding  net income and earnings per share as if the Company had accounted for
its employee stock options under the fair value method of SFAS No 123.

    Earnings Per Share

         In February 1997, the Financial  Accounting Standards Board issued SFAS
No. 128,  "Earnings per Share," which establishes new requirements for computing
and presenting earnings per share information. The Company, as required, adopted
this  statement  in the fourth  quarter of 1997.  Accordingly,  all earnings per
share and weighted average common shares  outstanding  information  presented in
these  financial  statements  and footnotes have been restated to conform to the
new  statement.  For each of the three years in the period  ended  December  31,
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 (in millions):

                                                         Year Ended December 31,

2.    ACQUISITION OF DUAL DRILLING COMPANY ("DUAL")

     On June 12, 1996,  the Company  acquired  Dual pursuant to an Agreement and
Plan of Merger among the Company,  a wholly owned  subsidiary of the Company and
Dual.  The  acquisition  was  approved  on that  date by Dual  stockholders  who
received 0.625 shares (1.25 shares giving effect to the two-for-one  stock split
effective  September 15, 1997) of the  Company's  common stock for each share of
Dual common stock.  The Company issued  approximately  10.1 million shares (20.1
million  shares  post  split)  of its  common  stock  to  Dual  stockholders  in
connection  with  the  acquisition,   resulting  in  an  acquisition   price  of
approximately $218.4 million.

     The acquisition of Dual was accounted for as a purchase and the acquisition
cost was  allocated to the assets  acquired  and  liabilities  assumed  based on
estimates of their respective fair values. The excess of the purchase price over
net assets  acquired of $114.3  million was  allocated  to goodwill and is being
amortized  over 40  years.  The  Company  completed  its  final  purchase  price
allocation and  determination of goodwill,  deferred taxes and other accounts in
the second quarter of 1997.

     The  following  unaudited  pro forma  information  shows  the  consolidated
results of operations  for the years ended December 31, 1996 and 1995 based upon
adjustments  to the  historical  financial  statements  of the  Company  and the
historical financial statements of Dual to give effect to the acquisition by the
Company as if such acquisition had occurred January 1, 1995 (in millions, except
per share data):

     In  May  1997,  the  Company  acquired  the  remaining  51%  interest  in a
jointly-owned  premium  jackup rig located in Southeast  Asia for  approximately
$21.7  million.  The  Company's  49%  interest in the jackup rig was  previously
acquired in the acquisition of Dual.

     In December 1997, the Company purchased a harsh environment, Gorilla class,
jackup  drilling rig and certain  related  equipment  for  approximately  $103.2
million  ($5.0  million of which was  recorded  as assets  held for  sale).  The
drilling rig was renamed the ENSCO 100 and is under bareboat  charter to Smedvig
asa, the seller of the rig,  which  charter the Company  expects will last until
the year 2000.

     In November 1996,  the Company  purchased a jackup rig located in Southeast
Asia for approximately $44.0 million.

    Notes due 2007 and Debentures due 2027

     In November  1997, the Company issued $300.0 million of unsecured debt in a
public  offering,  consisting of $150.0  million of 6.75% Notes due November 15,
2007 (the "Notes") and $150.0 million of 7.20%  Debentures due November 15, 2027
(the  "Debentures").  Interest  on the  Notes  and  the  Debentures  is  payable
semiannually  commencing May 15, 1998. The Notes and the Debentures  were issued
pursuant to a $500.0 million universal shelf  registration  statement filed with
the  Securities  and Exchange  Commission in October 1997. The net proceeds from
the offering totaled approximately $287.8 million after selling and underwriting
discounts  and the  settlement  of interest  rate  hedges.  Approximately  $75.0
million of the net proceeds were used to retire the Company's  revolving  credit
facility  and $103.2  million of the net  proceeds  were used to acquire a harsh
environment, Gorilla class, jackup rig.

     The Notes and  Debentures  may be redeemed at any time at the option of the
Company,  in whole or in part, at a price equal to 100% of the principal  amount
thereof plus accrued and unpaid interest,  if any, and a make-whole premium. The
indenture  under  which  the  Notes  and the  Debentures  were  issued  contains
limitations on the  incurrence of  indebtedness  secured by certain  liens,  and
limitations  on  engaging  in certain  sale/leaseback  transactions  and certain
merger, consolidation or reorganization  transactions.  The Notes and Debentures
are not subject to any sinking fund requirements.

    Senior Subordinated Notes due 2004

     At the June 12, 1996 acquisition date, Dual had outstanding  $100.0 million
(face amount) of 9.875% Senior  Subordinated  Notes due 2004 (the "Dual Notes").
In July 1996,  $5.0  million  (face  amount)  of the Dual  Notes  were  redeemed
pursuant  to an offer  required  to be made  under the  terms of the  indenture.
Additionally,  the Company  purchased  $23.2  million  (face amount) of the Dual
Notes on the open  market  during  1996.  At  December  31,  1997 and 1996,  the
carrying value of the Dual Notes in the Consolidated Financial Statements is net
of  the  amounts  redeemed  and  purchased  by the  Company,  and  includes  the
unamortized  premium  assigned  to  the  Dual  Notes  as a  result  of  purchase
accounting.  The Dual Notes are  unsecured  obligations  and are  guaranteed  by
certain of the former  Dual  subsidiaries.  The Dual Notes'  indenture  contains
certain restrictive covenants relating to debt, restricted payments, disposition
of proceeds of asset sales,  transactions  with  affiliates,  limitation  on the
payment  of  dividends  and  other  payment  restrictions,  limitations  on sale
leaseback transactions and restrictions on mergers,  consolidations and transfer
of assets. Interest on the Dual Notes is payable semiannually and the Dual Notes
are redeemable at the option of the Company, in whole or in part, at any time on
or after January 15, 1999.

    Secured term loans (non-recourse to the Company)

         A  subsidiary  of the Company  has two  financing  arrangements,  in an
original  principal  amount  totalling  $143.0  million,  with a subsidiary of a
Japanese  corporation in connection  with the  construction  of eight barge rigs
delivered to Venezuela in 1993 and 1994. The financing  arrangements  consist of
eight  secured term loans,  one for each barge rig. The eight secured term loans
bear  interest at an average  fixed rate of 8.17% and are each  repayable  in 60
equal  monthly  installments  of  principal  and  interest  ending in April 1998
through  January 2000.  The term loans are each secured by a specific barge rig,
which had an aggregate combined net book value of $107.0 million at December 31,
1997, and the charter  contract on each rig. The secured term loans are expected
to be  repaid  from the cash flow  generated  by the  eight  barge  rigs and are
without recourse to the Company.

    Secured term loans

         In  October  1993,  the  Company  entered  into a  $25.0  million  loan
agreement with a financial  institution.  The seven year secured term loan bears
interest  at a fixed rate of 7.91% per annum,  repayable  in 28 equal  quarterly
installments ending October 15, 2000. The term loan is collateralized by certain
of the  Company's  marine  transportation  vessels which had a combined net book
value of $35.4 million at December 31, 1997.  The loan  agreement  requires that
the Company maintain a specified minimum tangible net worth and that the Company
not exceed a certain ratio of liabilities to tangible net worth.

         In  December  1995,  in  connection  with the  purchase  of four supply
vessels that were  previously  leased,  the Company  entered into a $4.7 million
loan agreement  with the seller.  The five year secured term loan bears interest
at a fixed rate of 7.75% per annum, repayable in 20 equal quarterly installments
ending January 2001. The term loan is  collateralized by the four supply vessels
purchased  which had a combined  net book value of $4.1  million at December 31,
1997.

    Revolving credit facility

         At December 31, 1996, the Company had $125.1 million  outstanding under
its  revolving  credit  facility  with  a  group  of  international  banks  (the
"Facility").  The  Facility  carried  a  floating  interest  rate tied to London
InterBank  Offered  Rates,  which was 7.0% at December 31, 1996. The Company had
entered into interest rate swap agreements that effectively changed the floating
interest  rate on $48.0  million  of the  outstanding  Facility  to fixed  rates
ranging  from 6.835% to 7.48% per annum.  The  Facility  was  collateralized  by
certain of the  Company's  jackup  rigs,  which had a combined net book value of
$388.3  million at December 31, 1996.  The Facility was retired in November 1997
with proceeds from the Company's  Notes and  Debentures.  Upon  retirement,  the
Company recorded an  extraordinary  charge in the fourth quarter of 1997 of $1.0
million,  net of income taxes,  to write-off the  remaining  deferred  financing
costs associated with the revolving credit facility.

    Maturities

         Maturities of long-term  debt,  excluding  amortization  of discount or
premium,  is as follows:  $29.3  million in 1998;  $23.3  million in 1999;  $5.7
million in 2000; none in 2001 or 2002 and $371.8 million thereafter.

5.    STOCKHOLDERS' EQUITY

         At the Company's  annual meeting of  stockholders  on May 13, 1997, the
stockholders  approved an increase in the Company's  authorized shares of common
stock from 125.0 million shares to 250.0 million shares.

         In August 1997, the Company's Board of Directors approved a two-for-one
stock  split  of the  Company's  common  stock  effective  September  15,  1997.
Accordingly,  all references to weighted  average common shares  outstanding and
earnings per share amounts in the financial  statements  and footnotes have been
adjusted to reflect the two-for-one stock split.

</TABLE>


         At December 31, 1997 and 1996, the outstanding  shares of the Company's
common  stock,  net of treasury  shares,  were 142.2  million and 70.9  million,
respectively.

         On February 21, 1995,  the Board of Directors of the Company  adopted a
shareholder  rights plan and declared a dividend of one preferred share purchase
right (a "Right") for each share of the Company's  common stock  outstanding  on
March 6, 1995. Each Right initially entitled its holder to purchase 1/100th of a
share of the Company's Series A Junior Participating Preferred Stock for $50.00,
subject to  adjustment.  In March 1997,  the plan was  amended to  increase  the
purchase  price from $50.00 to  $250.00.  The Rights  generally  will not become
exercisable until 10 days after a public announcement that a person or group has
acquired  15% or  more  of the  Company's  common  stock  (thereby  becoming  an
"Acquiring  Person")  or the  commencement  of a tender or  exchange  offer upon
consummation  of  which  such  person  or  group  would  own  15% or more of the
Company's common stock (the earlier of such dates being called the "Distribution
Date").  Rights will be issued  with all shares of the  Company's  common  stock
issued from March 6, 1995 to the Distribution Date. Until the Distribution Date,
the Rights will be  evidenced by the  certificates  representing  the  Company's
common stock and will be transferrable  only with the Company's common stock. If
any person or group becomes an Acquiring Person,  each Right,  other than Rights
beneficially  owned by the Acquiring  Person (which will thereupon become void),
will  thereafter  entitle its holder to  purchase,  at the Rights'  then current
exercise  price,  shares of the Company's  common stock having a market value of
two times  the  exercise  price of the  Right.  If,  after a person or group has
become  an  Acquiring  Person,  the  Company  is  acquired  in a merger or other
business  combination  transaction or 50% or more of its assets or earning power
are sold, each Right (other than Rights owned by an Acquiring  Person which will
have become  void) will  entitle  its holder to  purchase,  at the Rights'  then
current exercise price, that number of shares of common stock of the person with
whom the Company has engaged in the foregoing  transaction (or its parent) which
at the time of such  transaction  will  have a market  value  of two  times  the


                                       31
<PAGE>

exercise  price of the Right.  After any person or group has become an Acquiring
Person,  the Company's  Board of Directors  may,  under  certain  circumstances,
exchange  each Right (other than Rights of the  Acquiring  Person) for shares of
the Company's  common stock having a value equal to the  difference  between the
market  value of the  shares  of the  Company's  common  stock  receivable  upon
exercise of the Right and the  exercise  price of the Right.  The  Company  will
generally  be entitled to redeem the Rights for $.01 per Right at any time until
10 days after a public  announcement that a 15% position has been acquired.  The
Rights expire on February 21, 2005.

6.    EMPLOYEE BENEFIT PLANS

    Stock Options

         The  Company  has an  employee  stock  option plan as part of the ENSCO
Incentive Plan (the "Incentive Plan"). The maximum number of shares with respect
to which awards may be made pursuant to the Incentive  Plan is 12.5 million.  Of
the 12.5 million  shares,  a minimum of 1.3 million are reserved for issuance of
incentive stock grants and a minimum of 1.3 million are reserved for issuance as
profit sharing grants.  Incentive stock options generally become  exercisable in
25% increments  over a four-year  period.  To the extent not exercised,  options
expire generally on the fifth anniversary of the date of grant.

         On February 10, 1998, the Company's Board of Directors voted to adopt a
new  employee   stock  option  plan,   subject  to  approval  by  the  Company's
stockholders.  If the new plan is approved by the  Company's  stockholders,  the
Incentive Plan will be suspended. The new plan is expected to contain provisions
similar to the Incentive Plan regarding stock options and stock grants.

         In May 1996, the stockholders  approved the Company's 1996 Non-Employee
Directors  Stock Option Plan  ("Directors  Plan").  Under the Directors  Plan, a
maximum of 600,000 shares are reserved for issuance.  Options  granted under the
Directors Plan become exercisable six months after the date of grant and expire,
if not exercised, five years thereafter.

         The exercise  price of stock options  under the Incentive  Plan and the
Directors  Plan is the  market  value of the  stock at the  date the  option  is
granted.  Accordingly, no compensation expense is recognized by the Company with
respect to such grants.

         Pro forma  information  regarding  net income and earnings per share is
required  by SFAS  No.  123,  and has  been  determined  as if the  Company  had
accounted  for its employee  stock  options  under the fair value method of that
statement. The fair value of each option grant is estimated on the date of grant
using the Black-Scholes option pricing model with the following weighted average
assumptions:

                                       1997         1996          1995

since the estimated fair value of stock options is amortized to expense over the
vesting period, and additional options may be granted in future years.

        At December 31, 1997,  1.2 million  shares were  available  for grant as
options or incentive  grants under the  Incentive  Plan and 528,000  shares were
available for grant as options under the Directors Plan.

    Incentive Stock Grants

        Key  employees,  who are in a position to  contribute  materially to the
Company's growth and development and to its long-term success,  are eligible for
incentive stock grants under the Incentive Plan through February 8, 1998. Shares
of common stock  subject to incentive  grants vest on such a basis as determined
by a committee of the Board of Directors.  Through 1997,  incentive stock grants
for 2.5 million  shares of common stock were granted,  of which 1.7 million were
vested at December 31, 1997. During 1997, 1996 and 1995,  incentive stock grants
for  100,000  shares,  50,000  shares and  105,000  shares,  respectively,  were
granted.  The  remaining  outstanding  incentive  stock  grants vest as follows:
204,500 in 1998,  199,500 in years 1999 and 2000,  37,500 in years 2001  through
2004, 25,500 in 2005, 15,000 in 2006 and 10,000 in 2007.

    Savings Plan

        The Company has a profit  sharing plan (the "ENSCO  Savings Plan") which
covers eligible employees with more than one year of service, as defined. Profit
sharing  contributions require Board of Directors approval and may be in cash or
grants of the  Company's  common  stock.  The Company  recorded  profit  sharing
contribution  provisions for the years ended December 31, 1997, 1996 and 1995 of
$8.4 million, $3.8 million and $1.7 million, respectively.

                                       33
<PAGE>

        The ENSCO  Savings Plan  includes a 401(k)  savings  plan feature  which
allows  eligible  employees  with more than three  months of service to make tax
deferred  contributions  to the plan. The Company makes  matching  contributions
based on the amount of  employee  contributions  and rates set by the  Company's
Board of Directors.  Matching  contributions  totaled $2.1 million, $1.1 million
and $0.7 million in 1997, 1996 and 1995, respectively.  The Company has reserved
1.0 million shares of common stock for issuance as matching  contributions under
the ENSCO Savings Plan.

    Supplemental Executive Retirement Plan

        The  Company's  Supplemental  Executive  Retirement  Plan  (the  "SERP")
provides a tax deferred  savings plan for certain highly  compensated  employees
whose  participation  in the profit  sharing and 401(k) savings plan features of
the ENSCO Savings Plan is restricted due to funding and contribution limitations
of the Internal  Revenue Code. The SERP is an unfunded plan and  eligibility for
participation   is  determined  by  the  Company's   Board  of  Directors.   The
contribution  and Company  matching  provisions of the SERP are identical to the
ENSCO Savings Plan,  except that each  participant's  contributions and matching
contributions  under the SERP are further  limited by contribution  amounts,  if
any, under the 401(k)  savings plan feature of the ENSCO Savings Plan.  Matching
contributions  totaled $56,000 in 1997 and $22,000 in both 1996 and 1995. A SERP
liability of $689,000 and $330,000 is included in Other  Liabilities at December
31, 1997 and 1996, respectively.

    Employee Retirement Plan

        Eligible  former  Penrod  employees  participate  in  a  noncontributory
defined benefit employee retirement plan. However, the plan was frozen effective
December 31, 1990. Accordingly, no additional participants may join the plan and
no additional benefits have been accrued for participants subsequent to December
31, 1990. The Company's  policy is to fund the plan based on the minimum funding
requirements  of the  Employee  Retirement  Income  Security Act of 1974 and tax
considerations.  The Company has recorded a plan termination  liability,  net of
plan  assets,  of $3.4  million,  which is  included in Accrued  Liabilities  at
December 31, 1997.  Management  intends to terminate  the plan when it is in the
best  financial  interest of the Company by  purchasing  annuities  or otherwise
providing for participants  under the plan. Net periodic pension expense for all
years presented was insignificant.

7.    INCOME TAXES

        The  Company  had  income of $240.5  million,  $92.8  million  and $33.2
million from its operations  before income taxes in the United States and income
of $135.3  million,  $49.9 million and $14.1 million from its operations  before
income taxes in foreign  countries for the years ended  December 31, 1997,  1996
and 1995, respectively.

        The  components  of the provision for income taxes for each of the three
years in the period ended December 31, 1997 are as follows (in millions):

        During 1996,  the Company  released the  remaining  $10.0 million of its
deferred tax asset valuation  allowance based on the assessment of the Company's
ability  to  realize  the  full  benefit  of  all  of  its  net  operating  loss
carryforwards.  In 1995,  $38.0  million  of the  deferred  tax asset  valuation
allowance was released,  of which $13.3 million was recorded as an adjustment to
goodwill.   The  adjustment  to  goodwill   represents  the  amount  related  to
pre-acquisition   net  operating   losses  of  an  acquired  entity   previously
anticipated to expire unutilized.

        The  consolidated  effective income tax rate for each of the three years
in the period ended December 31, 1997,  differs from the United States statutory
income tax rate as follows:

                                                    1997       1996        1995

        At December 31, 1997, the Company had net operating  loss  carryforwards
of  approximately  $64.3 million and foreign tax credit  carryforwards  of $14.9
million. If not utilized,  the net operating loss carryforwards expire from 1999
through 2007 and the foreign tax credit  carryforwards  expire from 2001 through
2002. As a result of certain  acquisitions in prior years,  the utilization of a
portion  of the  Company's  net  operating  loss  carryforwards  are  subject to
limitations imposed by the Internal Revenue Code of 1986.  However,  the Company
does not expect such  limitations  to have an effect upon its ability to utilize
its net operating loss carryforwards.


                                       35

     It is the policy of the  Company  to  consider  that  income  generated  in
foreign  subsidiaries  is  permanently  invested.  A significant  portion of the
Company's  undistributed foreign earnings at December 31, 1997 were generated by
controlled foreign corporations. A portion of the undistributed foreign earnings
were taxed,  for U.S. tax purposes,  in the year that such earnings arose.  Upon
distribution  of foreign  earnings in the form of  dividends or  otherwise,  the
Company may be subject to additional U.S. income taxes. However,  deferred taxes
related  to the  future  remittance  of  these  funds  are  not  expected  to be
significant to the financial statements of the Company.

8.    COMMITMENTS AND CONTINGENCIES

    Leases

     The  Company is  obligated  under  leases for  certain of its  offices  and
equipment.  Rental expense relating to operating leases was $3.9 million in 1997
and $3.1  million  for each of the years 1996 and 1995.  Future  minimum  rental
payments under the Company's  noncancellable  operating lease obligations having
initial or  remaining  lease  terms in excess of one year are as  follows:  $4.6
million in 1998; $2.8 million in 1999;  $1.7 million in 2000;  $700,000 in 2001;
$300,000 in 2002 and none thereafter.

    Insurance

     Prior  to its  acquisition  by the  Company,  Dual was  self-insured  for a
substantial portion of its maritime claims exposure, with self-insured limits of
up to $500,000 for each claim.  Effective June 12, 1996,  the Company  increased
Dual's  insurance  coverage to levels  consistent  with the  Company's  existing
policies  which,  among other things,  limits the exposure to maritime claims to
$25,000 for each claim. Based on current  information,  the Company has provided
adequate reserves for such claims.

    Litigation Settlement

     In February  1991,  a  subsidiary  of the Company  filed an action  against
TransAmerican  Natural Gas Corporation and related  subsidiaries  and affiliates
("TransAmerican")  seeking damages for breach of contract. On April 5, 1996, the
U.S.  District  court for the  Southern  District  of Texas,  Houston  Division,
entered a judgment against TransAmerican.  As a result of the judgment, on April
18, 1996, the subsidiary of the Company entered into a settlement agreement with
TransAmerican.  Under the terms of the settlement  agreement,  the subsidiary of
the Company received  approximately $7.3 million. In the second quarter of 1996,
the  Company  recorded  a gain of $6.4  million  in Other  Income,  net,  with a
corresponding  increase  in deferred  income tax expense of $2.2  million for an
after tax gain of $4.2 million.

    Letters of Credit

     The Company,  from time to time, maintains legally restricted cash balances
with banks as collateral for letters of credit issued by banks. These letters of
credit are required under certain drilling contracts and the Company's insurance
arrangement.  There were no  restricted  cash  balances  at December  31,  1997.
Restricted  cash  balances of $1.6  million at December 31, 1996 are recorded in
Prepaid Expenses and Other.

     At December 31, 1997, there were no other contingencies, claims or lawsuits
against the Company which,  in the opinion of management,  would have a material
effect on its financial condition or results of operations.

</TABLE>

     The estimated fair values were determined as follows:

     Notes, Debentures and Senior Subordinated Notes - Quoted market price.

     Other  long-term debt - Interest rates  currently  available to the Company
for issuance of debt with similar terms and remaining maturities.

     The  estimated  fair  value of the  Company's  cash  and cash  equivalents,
receivables,  trade payables and other liabilities  approximated  their carrying
values at December  31, 1997 and 1996.  The  Company has cash,  receivables  and
payables  denominated  in currencies  other than  functional  currencies.  These
financial assets and liabilities  create exposure to foreign  currency  exchange
risk.  When  warranted,  the Company  hedges such risk by entering into purchase
options or futures contracts.  The Company does not enter into such contracts to
engage in  speculation.  The notional  amounts of such contracts  outstanding at
December 31, 1997 and 1996 was insignificant and approximated market value.

     Concentration of Credit Risk. The Company provides services to the offshore
oil and gas industry and the Company's  customers consist primarily of major and
independent oil and gas producers as well as government-owned oil companies. The
Company performs ongoing credit  evaluations of its customers and generally does
not require material  collateral.  The Company maintains  reserves for potential
credit losses,  which to date have been within  management's  expectations.  The
Company's cash and cash equivalents are maintained in major banks and high grade
investments.  As a  result,  the  Company  believes  the  credit  risk  in  such
instruments is minimal.

12.    DISCONTINUED OPERATIONS

        Effective  September 30, 1995, the Company exited the technical services
business through the sale of substantially all of the assets of its wholly owned
subsidiary, ENSCO Technology Company. The sales price consisted of $11.8 million
in  cash,   an   interest-bearing   promissory   note  for  $3.6   million,   an
interest-bearing convertible promissory note for $2.5 million and the assumption
of $1.9 million of liabilities. In July 1996, the acquiring company successfully
completed a public  offering  which allowed the Company the right to convert the
$2.5 million convertible promissory note into common stock of the purchaser. The
Company  exercised this right and sold the common stock for $5.4 million in July
1996,  realizing a pre-tax gain of  approximately  $2.9 million on the sale. The
pre-tax  gain  of  $2.9  million  is  recorded  in  Other  Income,  net,  with a
corresponding  increase  in deferred  income tax expense of $1.1  million for an
after-tax gain of $1.8 million.  Also, as a result of the public  offering,  the
$3.6 million promissory note was paid in full in July 1996.

        As a  result  of  the  sale  of the  technical  services  business,  the
Company's financial  statements have been reclassified to present the net assets
and operating results of the Company's  technical services operations segment as
a  discontinued  operation.  Included  in  the  1995  Income  from  Discontinued
Operations is a gain on the sale discussed above of $5.2 million and income from
operations  for the  nine  months  ended  September  30,  1995 of $1.1  million.
Revenues from the technical services operations were $13.4 million in 1995.

                                   DEFINITIONS

        Unless by the context hereof a different  meaning is clearly  indicated,

hereinafter set forth:

     Sec.  1.1  Administrator  for the  purposes  of ERISA  means  the  Company;
provided,  that the Company,  by action of its  governing  body,  may  designate
another  person  or  entity,  including  the  Trustee,  the  Recordkeeper  or  a
Committee, as Administrator of the Plan.

     Sec. 1.2  Affiliated  Company  means the Company and any other entity which
is, along with the Company,  a member of a controlled group of corporations or a
controlled group of trades or businesses [as defined in Section 414(b) or (c) of
the Code],  any entity which along with the Company is included in an affiliated
service  group as defined in Section  414(m) of the Code,  and any other  entity
which is required to be aggregated  with the Company  pursuant to Section 414(o)
of the Code.

     Sec. 1.3 Allocation Date means each payroll period for Employees during the
Year or such other date or dates as the Administrator may establish from time to
time.

     Sec. 1.4 Alternate Payee means a person defined in Section 414(p)(8) of the
Code who is entitled to benefits under the Plan pursuant to a Qualified Domestic
Relations Order.

     Sec. 1.5 Annual  Compensation  means with respect to an Employee,  the base
salary or wages,  including overtime pay and field bonuses paid to such Employee
by an Employer which are includible in the Employee's gross income for the Year,
plus  amounts  applied  to  purchase  benefits  pursuant  to a salary  reduction
agreement under a cafeteria plan as defined in Section 125 of the Code sponsored
by an  Employer,  amounts  deferred  pursuant  to a salary  reduction  agreement
authorized in Section 3.1, and amounts  deferred  pursuant to a salary reduction
agreement  under any other plan  described in Sections  401(k) and 408(k) of the

Compensation  shall be  taken  into  account  by the Plan  with  respect  to any
Participant  [or,  beginning  January  1,  1998,  such  other  amount  as may be

                                       3

     Sec.  1.6  Beneficiary  means  any  person  or  fiduciary  designated  by a
Participant  or Former  Participant  in  accordance  with the terms  hereof  and
Section 401(a)(9) of the Code to receive benefits hereunder  following the death
of  such  Participant  or  Former  Participant.   Each  Participant  and  Former
Participant may, from time to time, select one or more  Beneficiaries to receive
benefits  pursuant to Section 12.1 in the event of the death of such Participant
or Former Participant.  Such selection shall be made in writing by Notice to the
Administrator.  Unless  the  provisions  of the  Plan  or a  Qualified  Domestic
Relations  Order  provide  otherwise,  the last such  selection  filed  with the
Administrator  shall control.  If at the date of death the Participant or Former
Participant is married, the Beneficiary shall be the surviving spouse unless the
spouse has consented in writing to the  designation  of some other  Beneficiary,
which  designation  may  not be  changed  without  spousal  consent  unless  the
voluntary  consent of the  spouse  (i)  expressly  permits  designations  by the
Participant or Former Participant  without any requirement of further consent by
the  spouse  and (ii)  acknowledges  that the  spouse has the right to limit the
consent to a specific  Beneficiary.  Such written  consent must  acknowledge the
effect  of  such  selection  and  such  consent  must  be  witnessed  by a  Plan
representative  or a notary  public.  Spousal  consent is not  required if it is
established to the satisfaction of the Plan  representative that the consent may
not be obtained (i) because the Participant or Former Participant has no spouse,
(ii)  because  the  spouse  cannot be  located  or (iii)  because  of such other
circumstances  as the Secretary of Treasury may by  regulations  prescribe.  Any
consent by a spouse (or establishment  that the consent of the spouse may not be
obtained) shall be effective only with respect to that spouse.  If more than one
Beneficiary  of a  particular  class  (primary  or  secondary)  is  entitled  to
benefits,  payments shall be made in equal shares to such Beneficiaries,  unless
some other specific  proportions  are clearly  designated by the  Participant or
Former Participant.  If more than one Beneficiary of a particular class (primary
or secondary) is named,  the interest of any deceased  Beneficiary of that class
shall pass to the surviving Beneficiary or Beneficiaries of that class except to
the  extent  that  the  designation   provides  for  payment  to  any  secondary
Beneficiary or Beneficiaries upon the death of a primary Beneficiary.

        If a selection is not made in  compliance  with these  provisions  or if
such  designated  persons  shall have died,  Beneficiary  means the first of the
following classes of successive  preference  beneficiaries  then surviving:  the
Participant's or Former Participant's:

        (a)     surviving spouse,

        (b)     descendants, per stirpes,

        (c)     parents in equal shares,

        (d)     brothers and sisters in equal shares, and

        (e)     estate.

effective with respect to the Plan.

     Sec. 1.8  Committee  means the committee  appointed  under Article XVIII to

become employees of such organization, adopts and assumes the Plan and the Trust
Agreement  as the  sponsor  with the consent of the Company and agrees to accept
the duties,  responsibilities and obligations of the sponsor of the Plan and the

organization  which adopts and assumes the sponsorship of the Plan and the Trust
Agreement.

security that qualifies as a qualifying employer security under ERISA.

     Sec. 1.11 Disability means a total and permanent  disability  suffered by a
Participant  which, in the opinion of the Administrator  (which opinion shall be
conclusive for purposes of the Plan) prevents such  Participant  from continuing
his work with all Employers.

Deferred/Thrift  Savings Plan and Trust  formerly  maintained  by Dual  Drilling

Company acquired Dual Drilling  Company.  The employees of Dual Drilling Company
who were eligible to  participate  in the Dual 401(k) Plan ceased to be eligible
to participate in that plan on June 30, 1996 and became  eligible to participate
in the Plan on July 1, 1996.  The governing body of the Company has approved the
merger  of the  Dual  401(k)  Plan  into  the  Plan as soon as  administratively
practicable  following  the  issuance  by the  National  Office of the  Internal
Revenue Service of a compliance  statement  pursuant to the application filed by
Dual Holding Company,  as successor sponsor to Dual Drilling Company of the Dual
401(k) Plan, under the Voluntary  Compliance  Resolution program of the Internal

        Sec. 1.13 Employee means any individual in the employ of an Employer who
is on an Employer's  United States  payroll,  excluding any Leased Employee that
Section  414(n)  of the  Code  treats  as an  Employee  of an  Employer,  unless
classification  of such Leased  Employee as an Employee is necessary to maintain
the qualification of the Plan.

        Sec. 1.14 Employer means the Company and any other  Affiliated  Company,

designation  shall become effective only when it shall have been accepted by the
governing  body of the Employer.  An Employer may revoke its  acceptance of such
designation at any time, but until such acceptance has been revoked,  all of the
provisions  of the Plan and  amendments  thereto shall apply to the Employees of
the Employer. In the event the designation of the Employer as such is revoked by
the  governing  body of the  Employer,  such  revocation  will  not be  deemed a
termination of the Plan.

        Sec. 1.15 Employer  Account means the portion of the Individual  Account
maintained  by the  Trustee or the  Recordkeeper  for each  Participant,  Former
Participant  or  Beneficiary,  reflecting  the monetary  value of such  person's
individual  interest in the Trust Fund  attributable  to an Employer's  Matching
Contributions  under Section 3.2 and the Employer profit sharing  contributions,
if any,  under Section 3.3. If the  Participant  was a participant in the Penrod
Thrift Plan as of December 31, 1993, his Employer  Account will also reflect his
individual  interest  in the  Trust  Fund  attributable  to the  balance  in his
matching account maintained under the Penrod Thrift Plan as of the Merger Date.

eligible Employee's participation in the profit sharing feature of the Plan, the
first day of the calendar month  coincident  with or next following the date the
Employee  satisfies the  eligibility  requirements of Section 2.1 for the profit
sharing feature of the Plan (the "Profit Sharing Entry Date"). Prior to April 1,

Contributions  made on the  Participant's  behalf pursuant to a salary reduction
agreement  described in Section 3.1 and  attributable to qualified  non-elective
contributions  under Section 3.4. If the Participant was a participant in either
the Penrod  Thrift  Plan as of  December  31, 1993 or the Dual 401(k) Plan as of
June 30, 1996, his 401(k)  Account will also reflect his individual  interest in

excludable  from the  individual's  gross income under Sections 125,  402(a)(8),
402(h) or 403(b) of the  Code].  If any Leased  Employee  shall be treated as an

                Compensation  not yet paid (A) to increase  or to  decrease  the
                whole percentage of his Annual  Compensation  [within the limits
                of Section 3.1(a)] to be used to determine his Salary  Reduction


                                       18

                Contributions  or (B) to cease  entirely such  contributions.  A
                Participant's  amended Salary  Reduction  Contribution  election
                shall be effective no earlier than the first day  following  the
                Valuation Date an amended salary  reduction  agreement is timely
                received in executed  form by the  Administrator,  or such other
                date as the  Administrator  may prescribe  from time to time. An
                amendment  to a salary  reduction  agreement,  including  one to
                cease Salary Reduction  Contributions,  is timely received if it
                is  received  by  the  Administrator  prior  to  the  applicable
                Valuation  Date. If a Participant  elects to cease making Salary
                Reduction  Contributions,  the  Participant  may  elect to again
                participate  in the 401(k) feature of the Plan and resume making
                contributions   to  the  Trust  Fund  under  Section  3.1(a)  by
                executing a new salary  reduction  agreement,  provided that the
                effective date of such new salary  reduction  agreement shall be
                no earlier than the first  Valuation Date of the next succeeding
                calendar  month  following  the  date the new  salary  reduction
                agreement   is  timely   received  in   executed   form  by  the
                Administrator, unless the Participant has previously amended his
                Salary  Reduction  Agreement  twice  during that Year,  in which
                case,  it shall be effective as of the first  Valuation  Date in
                the next succeeding Year.

                (iv)  Transfer  to  Ineligible   Employment  or  Termination  of
                Employment.  A  Participant's  salary  reduction  election shall
                terminate  automatically if the Participant transfers to a class
                of employment not eligible for  participation  in the Plan or if
                he terminates  his  employment as an Employee with the Employer.
                Upon  return of the  Participant  to  eligible  employment,  the
                Participant shall be permitted to execute a new salary reduction
                agreement and resume having contributions made to the Trust Fund
                on his behalf under Section 3.1(a),  provided that the effective
                date of the new salary  reduction  agreement shall be no earlier
                than the later of (A) the  first  Valuation  Date  after the new
                salary  reduction  agreement is received in executed form by the
                Administrator  or (B) the date the Participant  resumes eligible
                employment  with  an  Employer.  Transfers  of  Participants  to
                different   payroll   systems  among  the  Employers   shall  be
                administered by procedures established by the Administrator.

      Sec.  3.2 Employer   Matching  Contributions.  For each payroll period, an
Employer may contribute hereunder as a Matching  Contribution an amount equal to
a  stated  dollar  amount  or  a  stated  percentage  of  the  Salary  Reduction
Contribution, if any, made for such payroll period on behalf of each Participant
entitled to an allocation under Section 7.3;  provided that the Salary Reduction
Contribution  made on behalf of each  Participant for a payroll period for which
an Employer shall make a Matching  Contribution  shall be considered only to the
extent  that it does not exceed 6% of the  portion of the  Participant's  Annual
Compensation  paid during such payroll period,  unless the governing body of the


                                       19
<PAGE>

Company  determines  otherwise.  The Matching  Contributions for a Year shall be
determined  by the  governing  body of the  Company  in its  sole  and  absolute
discretion.  Matching  Contributions  made  pursuant  to this  Section  shall be
subject to the limitations  and  restrictions of Articles V and VI. The Matching
Contributions, if any, made pursuant to this Section 3.2 shall be reduced by the
forfeitures  for such Year under  Articles IV, V, XIV and XV that are designated
under  Section  14.5  by the  Company  to be  applied  to  reduce  the  Matching
Contributions  for the Year and such forfeitures  shall be allocated as provided
in Section 7.3 in lieu of such contributions.

     Sec.  3.3   Employer  Profit  Sharing  Contributions.  In  addition  to the
Matching  Contribution under Section 3.2, if any, for any Year, the Employer may
elect to make a voluntary profit sharing contribution (after taking into account
the  Matching  Contribution,  if  any,  under  Section  3.2)  on  behalf  of the
Participants  entitled to an  allocation  under  Section 7.4 for that Year in an
amount  determined  and authorized by the governing body of the Company for such
Year. The Employer profit sharing  contributions,  if any, made pursuant to this
Section 3.3 shall be allocated  along with the  forfeitures  for such Year under
Articles IV, V, XIV and XV, if any,  that are  designated  by the Company  under
Section 14.5 for allocation  under Section 7.4 with the Employer  profit sharing
contributions.

     Sec. 3.4   Employer Qualified  Non-Elective  Contributions.  To insure that
the Actual Deferral  Percentage tests of Section 401(k) of the Code as described
in Section 4.2 hereof or the Contribution  Percentage tests of Section 401(m) of
the Code as described  in Section 5.1 hereof are met for any Year,  an Employer,
under such rules and regulations as the Secretary of the Treasury may prescribe,
in addition to the Salary Reduction  Contributions made by the Employer pursuant
to Section 3.1, the Matching  Contributions  under  Section 3.2, if any, and any
Employer  profit sharing  contributions  under Section 3.3, may make  additional
contributions  which shall  constitute  "qualified  non-elective  contributions"
within  the  meaning  of  Section  401(m)(4)(C)  of the  Code on  behalf  of any
Non-Highly  Compensated  Employee  (as defined in Section  4.2)  selected by the
Company.  Each Year an Employer  shall  designate  the  portion,  if any, of the
qualified  non-elective  contributions  that it made for the Year that  shall be
considered  under Section 4.2 for the Actual  Deferral  Percentage  test and the
portion, if any, that shall be considered under Section 5.1 for the Contribution
Percentage test.

     Sec.   3.5   Time   and  Form  of   Contributions.   Payments  of  Employer
contributions  due with respect to any Year (i) pursuant to Section 3.2 shall be
made in Company  Stock and (ii)  pursuant to Section 3.3 may be made in cash (by
check or wire transfer), Company Stock or any combination thereof, as determined
by the  Company  in its  discretion.  In  addition  to  any  other  requirements
hereunder  relating  to the timing of  contributions,  contributions  made by an


                                       20
<PAGE>

Employer  pursuant to Sections  3.2, 3.3 or 3.4, if any, may be made at any time
and from time to time, except that the total  contribution for any Year shall be
paid in full not later than the time prescribed by law to enable the Employer to
obtain a deduction  therefor on its federal  income tax return for said Year. If
in advance  of a Year the  governing  body of the  Company  authorizes  Employer
contributions  pursuant to Section 3.2 or 3.3 for that Year, such governing body
may  provide  that all or a portion  of such  contributions  shall be  allocated
monthly,  quarterly or on some other basis rather than by payroll  period during
the Year or at the end of such  Year.  Contributions  made after the last day of
the Year but within the time for filing an Employer's  federal income tax return
(including  extensions  thereof) shall be deemed made as of the last day of that
Year if so directed by the Employer,  except such contributions  shall not share
in increases,  decreases, or income to the Trust Fund prior to the date actually
made.  Notwithstanding the foregoing, upon an Employer's request, a contribution
which was made upon a mistake of fact or conditioned upon initial  qualification
of the Plan  (application  for which is made by the time  prescribed  by law for
filing  the  Employer's  tax return  for the  taxable  year in which the Plan is
adopted,  or such later date as the Secretary of the Treasury may  prescribe) or
upon  deductibility of the contribution shall be returned to the Employer within
one year after  payment of the  contribution,  denial of the  qualification,  or
disallowance  of the deduction (to the extent  disallowed),  as the case may be;
provided,  however, the amount returned to an Employer due to mistake of fact or
denial of deductibility shall not be increased by any earnings thereon and shall
be reduced by any losses attributable to such amount.

     Sec. 3.6   Limit on Employer  Contributions.  Notwithstanding the foregoing
provisions of Sections 3.1, 3.2, 3.3 or 3.4, the contribution of an Employer for
any Year (whether made pursuant to Sections 3.1, 3.2, 3.3 or 3.4) shall be first
authorized by the governing  body of the Company and shall in no event exceed an
amount which will,  under the law then in effect,  be deductible by the Employer
in computing  its federal  taxes based on income for that Year.  As permitted by
Section  401(a)(27) of the Code, any Employer may make contributions to the Plan
without regard to net profits, current or accumulated.

     Sec. 3.7   Contributions May be Made with Respect to a Particular Employer.
In making its  determination  of  Matching  Contributions  and  Employer  profit
sharing  contributions  with  respect  to any Year,  the  governing  body of the
Company may make its  determination  separately  with respect to any Employer or
business or operating unit within an Employer;  provided, however, that any such
determination  must be  nondiscriminatory  within the  meaning  of the  Treasury
regulations  under  Section  401(a)(4)  of the Code and must satisfy the minimum
coverage  requirements  of  Section  410(b)  of the  Code.  In  such  case,  the
contribution  to such Employer or business or operating  unit within an Employer


                                       21
<PAGE>

shall be allocated  only to  Participants  who are Employees of such Employer or
business or operating unit within that Employer.

     Sec. 3.8 Manner of Making  Contributions.  All  contributions  to the Trust
Fund  shall  be  paid  directly  to  the  Trustee.   In  connection   with  each
contribution, the Employer shall provide the Recordkeeper with information that:

        (a) identifies  each  Participant on whose behalf  the  contribution  is
        being made and the amount thereof;

        (b) states whether the amount  contributed on behalf of the  Participant
        is a Salary Reduction Contribution, a Matching Contribution, an Employer
        profit sharing contribution,  a qualified non-elective  contribution,  a
        Rollover Contribution or a Transfer Contribution; and

        (c) directs the  investment of the amount  contributed  on behalf of the
        Participant.

     Sec. 3.9   Rollover and Transfer Contributions.  An Employee, regardless of
whether he is a Participant in the Plan, may, if authorized by the Administrator
and after  complying  with all  applicable  laws and filing with the Trustee the
form  prescribed by the  Administrator,  make a Rollover  Contribution or have a
Transfer  Contribution  made  on his  behalf  to the  Plan at any  time.  If the
Employee  is not a  Participant  hereunder,  his  Rollover  Account or  Transfer
Account shall  constitute his entire  interest under the Plan. The  Recordkeeper
shall allocate and credit a Rollover  Contribution  or Transfer  Contribution to
the  Employee's  Rollover  Account or Transfer  Account as of the Valuation Date
immediately  following the date on which the Rollover  Contribution  or Transfer
Contribution  is  made.  An  investment  election  on a form  prescribed  by the
Administrator  shall be submitted with the Employee's  Rollover  Contribution or
Transfer Contribution and shall direct that such contribution be invested in the
Investment  Funds  in  accordance  with  Section  22.8.  In no event  shall  the
existence  of a Rollover  Contribution  or  Transfer  Contribution  held for the
benefit of an Employee be construed to entitle the Employee to any amount in the
Plan to which such Employee is not otherwise entitled under the other provisions
of the Plan.

                                   Article IV

                          LIMITATIONS AND RESTRICTIONS
                        ON SALARY REDUCTION CONTRIBUTIONS

     Sec. 4.1   Dollar Limitation and Excess Elective Deferrals. For any taxable
year of a  Participant,  the aggregate  amount of (i) the  Participant's  Salary
Reduction  Contributions made pursuant to Section 3.1 for that taxable year, and
(ii) amounts  deferred by the  Participant  for that taxable year  pursuant to a
salary reduction agreement under any other plan, contract or agreement described

                                       22
<PAGE>

in Sections  401(k),  403(b) or 408(k) of the Code  sponsored  by an  Affiliated
Company shall not exceed the Annual  Deferral  Limitation for that taxable year.
The Annual Deferral  Limitation for the taxable year beginning in 1997 is $9,500
[or,  beginning  January 1,  1998,  such other  amount as the  Secretary  of the
Treasury may prescribe at the same time and in the same manner as provided under
Section  415(d) of the Code for adjusting the dollar  limitation in effect under
Section 415(b)(1)(A) of the Code].

        If the Salary  Reduction  Contributions  made on behalf of a Participant
for a taxable  year exceed the Annual  Deferral  Limitation  for that year,  the
amount of such  excess  shall be  referred  to as "Excess  Elective  Deferrals."
Excess Elective Deferrals  (adjusted for the income or loss attributable to such
excess amount) shall be distributed to the  Participant not later than the April
15  immediately  following  the taxable  year of the  Participant  for which the
Excess Elective Deferrals were made to the Plan. The Administrator  shall reduce
the amount of the Excess Elective  Deferrals for a taxable year distributable to
the Participant  under this Section 4.1 by the amount of Excess Salary Reduction
Contributions (as determined under Section 4.3), if any, previously  distributed
to  the   Participant   for  the  Year  beginning  in  that  taxable  year.  The
Administrator  shall  determine the net income or net loss in the same manner as
described in Section 4.3 for Excess Salary Reduction  Contributions,  except the
numerator of the allocation  fraction  shall be the amount of the  Participant's
Excess  Elective  Deferrals  for the taxable year under this Section 4.1 and the
denominator of the allocation fraction shall be the balance of the Participant's
401(k) Account  attributable to Salary Reduction  Contributions as of the end of
the taxable year  [without  regard to the net income or net loss for the taxable
year on that portion of the Participant's 401(k) Account]; provided, however, if
there  is a  loss  attributable  to  such  excess  amount,  the  amount  of  the
distribution adjusted for such loss shall be limited to an amount which does not
exceed the lesser of (i) the balance of the Participant's 401(k) Account or (ii)
the Salary  Reduction  Contributions  made on behalf of the Participant for that
taxable year. In adjusting a  Participant's  Excess  Elective  Deferrals for the
income or loss attributable to such Excess Elective Deferrals, effective for the
Year beginning  January 1, 1997, the income or loss  attributable to such excess
deferrals  for the "gap period"  shall not be  considered.  For purposes of this
Section 4.1, "gap period" shall mean the period  beginning with the first day of
the taxable year next  following the taxable year for which the Excess  Elective
Deferrals were made on behalf of the  Participant  and ending on the date of the
distribution. If Excess Elective Deferrals are distributed to a Participant from
the Plan  pursuant to this Section 4.1,  the Matching  Contribution,  if any, to
which such Excess Elective  Deferrals relate (plus any income and minus any loss
attributable thereto), determined after the application of Section 5.2, shall be
forfeited  (whether or not vested) at the time the Excess Elective Deferrals are
distributed, and the forfeitures shall be applied as set forth in Section 14.5.


                                       23
<PAGE>

        If the Participant  also (i) participates in one or more other qualified
cash or deferred  arrangements within the meaning of Section 401(k) of the Code,
including  the Dual  401(k)  Plan for the period  beginning  January 1, 1996 and
ending  June 30,  1996,  (ii) has an  employer  contribution  made on his behalf
pursuant to a salary  reduction  agreement  under Section 408(k) of the Code, or
(iii) has an  employer  contribution  made on his  behalf  pursuant  to a salary
reduction  agreement  toward the purchase of an annuity  contract  under Section
403(b) of the Code, and the sum of the elective deferrals [as defined in Section
402(g)(3) of the Code] that are made for the  Participant  during a taxable year
under  such  other  arrangements  and this  Plan  exceeds  the  Annual  Deferral
Limitation  for that taxable year,  the  Participant  shall,  not later than the
March 1 following  the close of his taxable  year for which the excess  elective
deferrals have been made,  notify the Administrator in writing of the portion of
the excess  elective  deferrals  that he wishes to be allocated to this Plan, if
any,  and request  that the Salary  Reduction  Contributions  made on his behalf
under this Plan be reduced by the allocable amount specified by the Participant.
If all plans,  contracts and agreements described in Section 401(k),  403(b) and
408(k) of the Code  pursuant to which the  Participant  is able to defer amounts
for a  taxable  year for  which  excess  elective  deferrals  have been made are
sponsored by an Affiliated  Company,  the Administrator shall determine to which
plan,  contract or agreement  (including the Plan) the excess elective deferrals
shall be allocated  for that taxable year and if the excess  elective  deferrals
are to be allocated to the Plan, the Administrator  shall notify the Trustee and
the  Participant  in writing not later than March 1 following  the close of that
taxable year.  Such  notification  shall be deemed to be a  notification  by the
Participant to the  Administrator.  The portion of the excess elective deferrals
that is allocated to this Plan, if any, shall be adjusted for income and loss in
the manner  provided above and shall then be  distributed to the  Participant no
later  than  the  immediately  following  April  15.  If  the  Salary  Reduction
Contributions  made on behalf of a Participant  for a taxable year do not exceed
the Annual Deferral  Limitation for that taxable year and the  Administrator has
not received any written Notice from the Participant (or deemed to have received
written Notice from the  Participant  pursuant to the provisions  hereof) by the
March 1 immediately following that taxable year notifying the Administrator that
the Participant  allocates a portion of the excess elective  deferrals,  if any,
for that taxable year to the Plan, the Administrator may assume that none of the
Salary  Reduction  Contributions  made on  behalf  of the  Participant  for that
taxable year constitute  Excess  Elective  Deferrals and that no distribution is
required  to be made from the  Participant's  401(k)  Account  pursuant  to this
Section 4.1.  Notwithstanding  the fact that Excess Elective Deferrals have been
(or will be) distributed to a Highly Compensated Employee as provided above, the
excess  amount of such  Salary  Reduction  Contributions  or the portion of such
Salary  Reduction  Contributions  that are deemed to constitute  Excess Elective
Deferrals by reason of the  Administrator's  or Participant's  written Notice of
allocation  hereunder shall still be treated as a Salary Reduction  Contribution

                                       24
<PAGE>

for  purposes of applying  the Actual  Deferral  Percentage  test  described  in
Section 4.2 hereof for the Year in which such  Excess  Elective  Deferrals  were
made,  except to the extent provided under rules  prescribed by the Secretary of
the Treasury.

     Sec. 4.2 Actual Deferral Percentage Tests. For each Year, the Administrator
shall determine  whether the aggregate  amount  allocated to each  Participant's
401(k) Account  attributable  to Salary  Reduction  Contributions  and qualified
non-elective   contributions   (that  are  designated   under  Section  3.4  for
consideration  under this Section  4.2) made for that Year shall  satisfy one of
the following tests, in addition to the test set forth in Article VI:

        (a) the  "Actual  Deferral  Percentage"  for  the  Year  for  the  group
        consisting  of all eligible  Highly  Compensated  Employees  (as defined
        below)  shall  not  exceed  the  "Actual  Deferral  Percentage"  for the
        preceding  Year for the  group  consisting  of all  eligible  Non-Highly
        Compensated Employees (as defined below) multiplied by 1.25; or

        (b) the  "Actual  Deferral  Percentage"  for  the  Year  for  the  group
        consisting of all eligible Highly Compensated Employees shall not exceed
        the  lesser  of (i) 200% of the  "Actual  Deferral  Percentage"  for the
        preceding  Year for the  group  consisting  of all  eligible  Non-Highly
        Compensated  Employees or (ii) the "Actual Deferral  Percentage" for the
        preceding  Year for the  group  consisting  of all  eligible  Non-Highly
        Compensated  Employees plus two percentage  points or such lesser amount
        as the Secretary of the Treasury shall prescribe.

Notwithstanding  subsections  (a)  and (b)  above,  the  Company  may  elect  in
accordance with Internal  Revenue  Service Notice 97-2,  1997-2 IRB for the Year
beginning  January 1, 1997 and in  accordance  with Treasury  regulations  under
Section  401(k) of the Code for  Years  beginning  after  December  31,  1997 to
determine  compliance with either of the tests under subsection (a) or (b) for a
Year by reference to the Actual Deferral  Percentage of the eligible  Non-Highly
Compensated  Employees  for  the  current  Year  in  lieu  of  determining  such
compliance  based on the Actual Deferral  Percentage of the eligible  Non-Highly
Compensated Employees for the preceding Year.

        For  purposes  of this  Article IV, the  following  terms shall have the
following meanings:

        (a) "Actual  Deferral  Percentage" for a Year or a preceding Year means,
        with respect to the group consisting of the eligible Highly  Compensated

                                       25
<PAGE>

        Employees  and  the  group   consisting   of  the  eligible   Non-Highly
        Compensated  Employees,  the average  (expressed as a percentage) of the
        ratios,  calculated  separately for each Employee in each such group and
        rounded to the nearest  one-hundredth  of one percent,  of the amount of
        Salary Reduction Contributions and qualified non-elective  contributions
        (that are  designated  under  Section 3.4 for  consideration  under this
        Section 4.2) allocated to each  Employee's  401(k) Account under Section
        7.2 and  Section  7.5,  respectively,  (unreduced  in the case of Highly
        Compensated  Employees  by  distributions  made  to  any  such  Employee
        pursuant  to  Section  4.1  hereof)  for such  Year or  preceding  Year,
        whichever is applicable,  to such  Employee's  Annual  Compensation  [as
        defined  in  subsection  (c) below]  paid or accrued  during the Year or
        preceding  Year,  whichever is applicable,  in which the Employee was an
        eligible Highly Compensated Employee or eligible Non-Highly  Compensated
        Employee.

        (b) "Actual Deferral Ratio" means each separately calculated ratio under
        subsection (a) above. An Employee who is considered a Highly Compensated
        Employee under Section 1.20 or a Non-Highly  Compensated  Employee under
        Section 1.29 shall considered an "eligible Highly Compensated  Employee"
        or an "eligible  Non-Highly  Compensated  Employee" for purposes of this
        Section  4.2 for  each  Year he is  employed  by an  Employer  if he has
        satisfied  the  eligibility  requirements  of Article  II and  reached a
        401(k)  Entry  Date  on  which  he  could  have  become  a  Participant,
        regardless  of whether  (i) he has  elected to have an  Employer  make a
        Salary  Reduction  Contribution  to the Plan on his behalf under Section
        3.1 for that Year, (ii) his right to make Salary Reduction Contributions
        to the Plan for that Year has been totally or partially  suspended under
        Section 15.5(d) due to his receipt of a hardship distribution,  or (iii)
        he is suspended  from further  contributions  during the Year due to the
        limitations  of Section 415 of the Code as  described  in Article  VIII.
        Moreover,  the eligible Non-Highly Compensated Employees for a preceding
        Year shall be  determined  for that Year as described  in the  preceding
        sentence  and shall not be affected by any such  Non-Highly  Compensated
        Employee's  status  as  an  Employee,  Highly  Compensated  Employee  or
        Non-Highly Compensated Employee for the current Year. Consequently,  for
        purposes of this Section 4.2, the Actual  Deferral Ratio for each Highly
        Compensated Employee and Non-Highly Compensated Employee who is eligible
        to,  but does  not  elect to have an  Employer  make a Salary  Reduction
        Contribution  on his  behalf  to the Plan for a Year,  shall be zero for
        that  Year,   unless  the  Employer   makes  a  qualified   non-elective
        contribution  to the  Plan for a Year to  satisfy  the  Actual  Deferral
        Percentage  tests, in which case the Actual Deferral Ratio for each such
        Non-Highly  Compensated  Employee  shall be the ratio of that portion of
        the qualified  non-elective  contribution  attributable to contributions

                                       26
<PAGE>

        made by the  Employer to satisfy the Actual  Deferral  Percentage  tests
        which is allocated to his 401(k)  Account under Section 7.5 for the Year
        to his Annual  Compensation paid or accrued during the Year in which the
        Employee was an eligible Non-Highly Compensated Employee.

                If any Employee who is an eligible Highly  Compensated  Employee
        is a participant in two or more cash or deferred arrangements  described
        in  Section  401(k) of the Code  that are  maintained  by an  Affiliated
        Company,  excluding  any such  arrangement  that is part of an  employee
        stock ownership plan [as defined in Section  4975(e)(7) of the Code] for
        purposes of determining  his ratio under this Section 4.2, all such cash
        or  deferred  arrangements  shall be  treated  as one  cash or  deferred
        arrangement to the extent required under Section 401(k) of the Code. For
        purposes  of this  Section  4.2,  if two or more  plans or  arrangements
        described in Section  401(k) of the Code are considered one plan for the
        purposes of Sections  401(a)(4) or 410(b) of the Code, such arrangements
        shall be treated as a single arrangement, and if the plans use different
        plan years,  the  Administrator  shall  determine  the  combined  Salary
        Reduction  Contributions and ratio on the basis of the plan years ending
        in the same calendar year. The  Recordkeeper  shall maintain  records to
        demonstrate  compliance with the tests under this Section 4.2, including
        the extent to which the Plan used qualified  non-elective  contributions
        made pursuant to Section 3.4 to satisfy a test.

        (c) "Annual  Compensation"  means for a particular  Year beginning on or
        after January 1, 1995, the definition of compensation  determined by the
        Administrator to be used under this Section 4.2 for that Year,  provided
        that any such definition of compensation  must satisfy Section 414(s) of
        the Code as determined under Treas. Reg. ss.1.414(s)-1(c).

     Sec.  4.3   Adjustments  Required to Satisfy an Actual Deferral  Percentage
Test. If Salary Reduction  Contributions made for any Year do not satisfy one of
the tests set forth in Section  4.2,  the excess  amount that would  result in a
test being  satisfied for that Year if it had not been made to the Plan shall be
referred to as an "Excess Salary Reduction  Contribution"  and the Administrator
shall,  in its  sole and  absolute  discretion  and  notwithstanding  any  other
provision of the Plan to the contrary (but subject to the provisions of Sections
4.4  and  4.5),  make  appropriate  adjustments  pursuant  to one or more of the
following provisions:

        (a)  Within 2 1/2  months  following  the close of the Year for which an
        Excess  Salary  Reduction  Contribution  was made,  if  administratively
        possible, and not later than the close of the Year immediately following
        the Year for which an Excess Salary Reduction Contribution was made, the
        Excess Salary Reduction Contribution (plus any income and minus any loss
        attributable  thereto) shall be  distributed  to the Highly  Compensated
        Employees  to whose  401(k)  Accounts  all or a portion  of such  Excess
        Salary  Reduction  Contribution  was  allocated  first from such  Highly


                                       27
<PAGE>

        Compensated  Employees'  unmatched Salary Reduction  Contributions,  and
        then if  necessary,  from such  Highly  Compensated  Employees'  matched
        Salary  Reduction  Contributions;  provided,  however,  that if  matched
        Salary  Reduction  Contributions  are  distributed  to correct an Excess
        Salary Reduction  Contribution,  the Matching Contribution to which such
        Excess Salary Reduction  Contribution relates (plus any income and minus
        any loss  attributable  thereto)  shall  be  forfeited  (whether  or not
        vested)  at  the  time  the  Excess  Salary  Reduction  Contribution  is
        distributed and the forfeiture  shall be applied as set forth in Section
        14.5; or

        (b) Within the time  prescribed by law to enable an Employer to obtain a
        deduction for a  contribution  on its federal  income tax return for the
        Year for which an Excess Salary  Reduction  Contribution  was made,  the
        Employer shall, if the conditions  applicable to qualified  non-elective
        contributions  under final Treasury  regulations issued by the Secretary
        of  the  Treasury   are   satisfied,   make  a  qualified   non-elective
        contribution   pursuant  to  Section  3.4  on  behalf  of  the  eligible
        Non-Highly  Compensated  Employees  (as defined in Section 4.2) who meet
        the  requirements of Section 7.5 in an amount  sufficient to satisfy one
        of the tests set forth in Section 4.2  [before or after the  application
        of subsection (a) above].

The  amount of the  Excess  Salary  Reduction  Contributions  to be  distributed
pursuant to subsection (a) hereof shall be determined by a leveling method under
which the Actual  Deferral  Ratio of the Highly  Compensated  Employee  with the
highest dollar amount of Salary Reduction Contributions is reduced to the extent
required (i) to enable the Plan to satisfy one of the Actual Deferral Percentage
tests  set  forth  in  Section  4.2 or (ii) to  cause  such  Highly  Compensated
Employee's  dollar amount of Salary Reduction  Contributions to equal the dollar
amount of Salary Reduction Contributions of the Highly Compensated Employee with
the next highest dollar amount of Salary Reduction Contributions. This procedure
shall be repeated until the Plan satisfies one of the Actual Deferral Percentage
tests  set forth in  Section  4.2.  Once the Plan  satisfies  one of the  Actual
Deferral   Percentage   tests,   the  amount  of  the  Excess  Salary  Reduction
Contributions for each Highly Compensated  Employee who had his Salary Reduction
Contributions reduced under the preceding sentences shall be equal to the dollar
amount that his Salary Reduction  Contributions were reduced under the preceding
sentences,  reduced by the amount of Excess Elective  Deferrals for the Year, if
any, that have been previously distributed under Section 4.1 to the Employee for
the taxable year ending in that Year.

        The income or loss  attributable  to the  portion  of the Excess  Salary
Reduction  Contributions  for a Year  that  are to be  distributed  to a  Highly
Compensated  Employee hereunder shall be determined by multiplying the amount of
the income or loss allocable to the Participant's 401(k) Account for the Year by
a fraction, the numerator of which is the portion of the Excess Salary Reduction


                                       28
<PAGE>

Contributions  for the Year that are to be distributed to that  Participant  and
the denominator of which is the balance of the  Participant's  401(k) Account on
the last day of the Year after  adjustment as of such date under Section 9.2. In
adjusting a Participant's  Excess Salary Reduction  Contributions for the income
or loss  attributable  to such  excess  contributions,  effective  for the  Year
beginning  January  1,  1997,  the income or loss  attributable  to such  excess
contributions for the "gap period" shall not be considered. For purposes of this
Section 4.3, "gap period" shall mean the period  beginning with the first day of
the  Year  next  following  the Year  for  which  the  Excess  Salary  Reduction
Contributions  were made on behalf of the  Participant and ending on the date of
the distribution.

     Sec. 4.4   Additional  Adjustments of Salary Reduction  Contributions.  For
purposes of assuring  compliance  with the Actual Deferral  Percentage  tests of
Section 4.2 hereof, the Administrator may, in its sole and absolute  discretion,
make  such   adjustments,   reductions  or  suspensions   to  Salary   Reduction
Contribution rates of Participants who are Highly Compensated  Employees at such
times and in such amounts as the Administrator  shall reasonably deem necessary,
including prospective  reductions of Salary Reduction  Contributions at any time
prior to or within the Year.  The  Administrator  shall  make such  adjustments,
reductions or suspensions  based upon periodic  reviews of the Salary  Reduction
Contribution rates of Highly Compensated  Employees during the Year and may make
such adjustments,  reductions or suspensions in any amount  notwithstanding  any
other provisions  hereof. In addition,  the  Administrator  shall take any other
action to assure  compliance with the Actual Deferral  Percentage tests as shall
be prescribed by the Secretary of the Treasury.

     Sec.  4.5   Other  Permissible  Methods  of  Testing  and  Correction.  The
provisions of this Article IV are intended to conform with  Sections  401(k) and
402(g) of the Code.  In the event that the  Administrator  determines,  based on
changes  to the Code or  interpretations  or  guidance  issued  by the  Internal
Revenue Service, that the requirements of such Code sections may be applied in a
manner different from that prescribed in this Article IV, the  Administrator may
make appropriate  adjustments to the  administration  of the Plan to incorporate
such changes to the Code or interpretations or guidance. If a change to the Code
or interpretations or guidance issued by the Internal Revenue Service results in
more than one  additional  option in the manner in which this  Article IV may be
administered,  the Administrator shall have the limited discretion to select the
option to be used,  provided that such option, when compared to the other option
or options,  results in the  smallest  adjustment  to  Participants'  Individual
Accounts.

                         LIMITATIONS AND RESTRICTIONS ON
                             MATCHING CONTRIBUTIONS

     Sec. 5.1 Contribution  Percentage  Tests. For each Year, the Employer shall
determine,  after first applying the provisions of Section  4.3(a),  whether the
sum  of (i)  the  amounts  allocated  to  each  Participant's  Employer  Account
attributable  to  Matching  Contributions,  if  any,  made  for  that  Year  and
forfeitures  that are  allocated  under  Section  7.3 for that Year and (ii) the
amount allocated to each Participant's  401(k) Account attributable to qualified
non-elective   contributions   (that  are  designated   under  Section  3.4  for
consideration  under this  Section  5.1) for that Year shall  satisfy one of the
following tests, in addition to the test set forth in Article VI:

        (a) the "Contribution  Percentage" for the Year for the group consisting
        of all eligible  Highly  Compensated  Employees (as defined below) shall
        not exceed the "Contribution  Percentage" for the preceding Year for the
        group consisting of all eligible  Non-Highly  Compensated  Employees (as
        defined below) multiplied by 1.25; or

        (b) the "Contribution  Percentage" for the Year for the group consisting
        of all eligible Highly Compensated Employees shall not exceed the lesser
        of (i) 200% of the "Contribution  Percentage" for the preceding Year for
        the group consisting of all eligible Non-Highly Compensated Employees or
        (ii) the "Contribution  Percentage" for the preceding Year for the group
        consisting of all eligible  Non-Highly  Compensated  Employees  plus two
        percentage points or such lesser amount as the Secretary of the Treasury
        shall prescribe.

Notwithstanding  subsections  (a)  and (b)  above,  the  Company  may  elect  in
accordance with Internal  Revenue  Service Notice 97-2,  1997-2 IRB for the Year
beginning  January 1, 1997 and in  accordance  with Treasury  regulations  under
Section  401(m) of the Code for  Years  beginning  after  December  31,  1997 to
determine  compliance with either of the tests under subsection (a) or (b) for a
Year by  reference to the  Contribution  Percentage  of the eligible  Non-Highly
Compensated  Employees  for  the  current  Year  in  lieu  of  determining  such
compliance  based on the  Contribution  Percentage  of the  eligible  Non-Highly
Compensated Employees for the preceding Year.

        For  purposes  of this  Article V, the  following  terms  shall have the
following meanings:

        (a) "Contribution Percentage" for a Year or a preceding Year means, with
        respect  to the group  consisting  of the  eligible  Highly  Compensated
        Employees  and  the  group   consisting   of  the  eligible   Non-Highly
        Compensated  Employees,  the average  (expressed as a percentage) of the
        ratios,  calculated  separately for each Employee in each such group and


                                       30
<PAGE>

        rounded to the nearest  one-hundredth of one percent,  of the sum of (i)
        the amount of Matching Contributions,  if any, and forfeitures allocated
        to each Employee's  Employer  Account under Section 7.3 for such Year or
        preceding Year,  whichever is applicable,  after reduction for forfeited
        Matching  Contributions,  if any,  under  Section  4.3(a),  and (ii) the
        amount  allocated to each  Employee's  401(k)  Account under Section 7.5
        attributable   to  qualified   non-elective   contributions   (that  are
        designated under Section 3.4 for  consideration  under this Section 5.1)
        for such  Year or  preceding  Year,  whichever  is  applicable,  to such
        Employee's Annual Compensation [as defined in subsection (c) below] paid
        or accrued during the Year or preceding  Year,  whichever is applicable,
        in which the Employee  was an eligible  Highly  Compensated  Employee or
        eligible Non-Highly Compensated Employee.

        (b) "Actual  Contribution Ratio" means each separately  calculated ratio
        under  subsection  (a) above.  An Employee  who is  considered  a Highly
        Compensated  Employee  under  Section 1.20 or a  Non-Highly  Compensated
        Employee  under  Section 1.29 shall be  considered  an "eligible  Highly
        Compensated  Employee" or an "eligible Non-Highly  Compensated Employee"
        for  purposes  of this  Section  5.1 for each Year he is  employed by an
        Employer if he has satisfied the eligibility  requirements of Article II
        and  reached  a  401(k)  Entry  Date on which  he  could  have  become a
        Participant, regardless of whether he elected to have an Employer make a
        Salary  Reduction  Contribution  to the Plan on his behalf under Section
        3.1 and is eligible to receive an allocation of a Matching  Contribution
        under  Section  7.3 for that Year.  Moreover,  the  eligible  Non-Highly
        Compensated  Employees for a preceding Year shall be determined for that
        Year as described in the preceding sentence and shall not be affected by
        any such Non-Highly Compensated Employee's status as an Employee, Highly
        Compensated Employee or Non-Highly  Compensated Employee for the current
        Year.  Consequently,  for  purposes  of this  Section  5.1,  the  Actual
        Contribution Ratio for each Highly  Compensated  Employee and Non-Highly
        Compensated  Employee  who is eligible to, but does not elect to have an
        Employer make a Salary Reduction  Contribution on his behalf to the Plan
        for a Year,  shall be zero for that  Year,  unless an  Employer  makes a
        qualified  non-elective  contribution  to the Plan for a Year to satisfy
        the Contribution Percentage tests, in which case the Actual Contribution
        Ratio for each such Non-Highly  Compensated  Employee shall be the ratio
        of that portion of the qualified non-elective  contribution attributable
        to  contributions  made  by an  Employer  to  satisfy  the  Contribution
        Percentage  tests which is allocated to his 401(k) Account under Section
        7.5 for the Year to his Annual  Compensation  paid or accrued during the
        Year in  which  the  Employee  was an  eligible  Non-Highly  Compensated
        Employee.

                For  purposes  of this  Section  5.1, if two or more plans of an
        Employer to which matching  contributions  within the meaning of Section


                                       31
<PAGE>

        401(m)(4)(A) of the Code, employee voluntary after-tax  contributions or
        elective  deferrals  within the meaning of Section  401(m)(4)(B)  of the
        Code are made are treated as one plan for purposes of Sections 401(a)(4)
        and 410(b) of the Code,  [other  than the  average  benefits  test,  and
        excluding  allocations under an employee stock ownership plan as defined
        in Section 4975(e)(7) or 409 of the Code, or the portion of a plan which
        constitutes  an  employee  stock  ownership  plan],  such plans shall be
        treated as one plan for  purposes of this  Section 5.1, and if the plans
        use different plan years, the Administrator shall determine the combined
        Matching  Contributions  and the  ratio on the  basis of the plan  years
        ending  in the same  calendar  year.  The  Recordkeeper  shall  maintain
        records to demonstrate compliance with the tests under this Section 5.1,
        including  the  extent  to which the Plan  used  qualified  non-elective
        contributions  made  pursuant  to  Section  3.4 to  satisfy  a test.  In
        addition, if any Employee who is an eligible Highly Compensated Employee
        participates  in two or more plans  described  in Section  401(a) of the
        Code  which  are  maintained  by an  Affiliated  Company  to which  such
        contributions are made, all such  contributions  shall be aggregated for
        purposes of this Section 5.1 to the extent required under Section 401(m)
        of the Code.

        (c) "Annual  Compensation"  means for a particular  Year beginning on or
        after January 1, 1995, the definition of compensation  determined by the
        Administrator to be used under this Section 5.1 for that Year,  provided
        that any such definition of compensation  must satisfy Section 414(s) of
        the Code as determined under Treas. Reg. ss.1.414(s)-1(c).

     Sec.  5.2   Adjustments Required to Satisfy a Contribution Percentage Test.
If Matching Contributions, if any, made for any Year and allocated under Section
7.3 do not satisfy one of the tests set forth in Section 5.1, the excess  amount
that would result in a test being satisfied for the Year if it had not been made
to the Plan shall be referred to as an "Excess  Matching  Contribution"  and the
Administrator shall, in its sole and absolute discretion and notwithstanding any
other provision hereof, make appropriate adjustments in accordance with Sections
401(a)(4)  and  401(m) of the Code  (and the  Treasury  regulations  thereunder)
pursuant to  subsections  (a) and (b), or pursuant to subsection  (c) in lieu of
the  application  of  subsections  (a) and (b), or pursuant to subsection (c) in
addition to the  application  of  subsections  (a) and (b), as determined by the
Administrator, as follows:

        (a) To the extent that the portion of the Excess  Matching  Contribution
        for the Year  allocable to an Employer  Account of a Highly  Compensated
        Employee is  nonforfeitable  under  Section  14.2,  such  nonforfeitable
        portion (plus any income and minus any loss attributable  thereto) shall
        be distributed to the Highly  Compensated  Employee  within 2 1/2 months
        following the close of that Year, if administratively  possible, and not
        later than the close of the Year immediately following that Year; and

                                       32
<PAGE>

        (b) To the extent that the portion of the Excess  Matching  Contribution
        for the Year  allocable to an Employer  Account of a Highly  Compensated
        Employee  is  forfeitable  under  Section  14.2,  within  2  1/2  months
        following the close of that Year, if administratively  possible, and not
        later than the close of the Year  immediately  following  that Year such
        forfeitable  portion  (plus any income  and minus any loss  attributable
        thereto) shall be forfeited and applied as set forth in Section 14.5; or

        (c) In lieu of or in addition to the  application of subsections (a) and
        (b) above,  within the time  prescribed  by law to enable an Employer to
        obtain a deduction for a  contribution  on its federal income tax return
        for the Year for which an Excess  Matching  Contribution  was made,  the
        Employer shall, if the conditions  applicable to qualified  non-elective
        contributions  under final Treasury  regulations issued by the Secretary
        of the Treasury are satisfied, make a qualified nonelective contribution
        pursuant to Section 3.4 on behalf of the eligible Non-Highly Compensated
        Employees (as defined in Section 5.1) in an amount sufficient to satisfy
        one of the  tests  set  forth  in  Section  5.1  [before  or  after  the
        application of subsections (a) and (b)].

The amount of the Excess Matching  Contributions  to be distributed or forfeited
pursuant to  subsections  (a) and (b) hereof shall be  determined  by a leveling
method  under  which the Actual  Contribution  Ratio of the  Highly  Compensated
Employee with the highest dollar amount of Matching  Contributions is reduced to
the extent  required  (i) to enable the Plan to satisfy one of the  Contribution
Percentage  tests  set  forth  in  Section  5.1 or (ii)  to  cause  such  Highly
Compensated  Employee's  dollar  amount of Matching  Contributions  to equal the
dollar amount of Matching  Contributions of the Highly Compensated Employee with
the next highest dollar amount of Matching  Contributions.  This procedure shall
be repeated until the Plan satisfies one of the  Contribution  Percentage  tests
set  forth in  Section  5.1.  Once the Plan  satisfies  one of the  Contribution
Percentage tests, the amount of the Excess Matching  Contributions for each such
Highly Compensated Employee who had his Matching Contributions reduced under the
preceding  sentences  shall be  equal to the  dollar  amount  that his  Matching
Contributions were reduced under the preceding sentences.

        The income or loss  attributable  to the portion of the Excess  Matching
Contributions  for a Year  that are to be  distributed  to a Highly  Compensated
Employee  or  forfeited  from  his  Employer  Account  shall  be  determined  by
multiplying  the amount of the  income or loss  allocable  to the  Participant's
Employer  Account  for the Year by a  fraction,  the  numerator  of which is the
portion  of the  Excess  Matching  Contributions  for the  Year  that  are to be


                                       33
<PAGE>

distributed to that  Participant or forfeited from his Employer  Account and the
denominator of which is the balance of the Participant's Employer Account on the
last day of the Year after adjustment as of such date under Section 9.2.

        In  adjusting a  Participant's  Excess  Matching  Contributions  for the
income or loss attributable to such excess contributions, effective for the Year
beginning  January  1,  1997,  the income or loss  attributable  to such  excess
contributions for the "gap period" shall not be considered. For purposes of this
Section 5.2, "gap period" shall mean the period  beginning with the first day of
the Year next  following  the Year for which the Excess  Matching  Contributions
were  made  on  behalf  of  the  Participant  and  ending  on  the  date  of the
distribution.

       Sec. 5.3  Testing of Salary Reduction  Contributions  Under  Contribution
Percentage Test.  Notwithstanding the foregoing  provisions of this Article V or
of Article IV, all or a portion of the Salary  Reduction  Contributions  made on
behalf of eligible Non-Highly  Compensated  Employees may be treated as Matching
Contributions made on behalf of such eligible Non-Highly  Compensated  Employees
for the purpose of meeting the Contribution Percentage test set forth in Section
5.1,  provided that the Actual  Deferral  Percentage  test of Section 4.2 can be
met,  both  when  the  Salary  Reduction   Contributions   treated  as  Matching
Contributions   hereunder  are  included  in  performing  such  Actual  Deferral
Percentage  test and when such Salary  Reduction  Contributions  are excluded in
performing such Actual Deferral  Percentage test. Except for purposes of meeting
the  Contribution  Percentage  test  of  Section  5.1  to the  extent  described
hereunder,  any such Salary Reduction Contributions shall continue to be treated
as Salary Reduction Contributions for all other purposes of the Plan.

       Sec.  5.4 Other  Permissible  Methods of  Testing  and  Corrections.  The
provisions of this Article V are intended to conform with Section  401(m) of the
Code. In the event that the  Administrator  determines,  based on changes to the
Code or interpretations or guidance issued by the Internal Revenue Service, that
the  requirements of such Code section may be applied in a manner different from
that  prescribed  in this  Article  V, the  Administrator  may make  appropriate
adjustments to the administration of the Plan to incorporate such changes to the
Code or interpretations or guidance.  If a change to the Code or interpretations
or guidance  issued by the  Internal  Revenue  Service  results in more than one
additional option in the manner in which this Article V may be administered, the
Administrator shall have the limited discretion to select the option to be used,
provided that such option, when compared to the other option or options, results
in the smallest adjustment to Participants' Individual Accounts.

                                   Article VI

                       AGGREGATE LIMIT ON ACTUAL DEFERRAL
                          AND CONTRIBUTION PERCENTAGES

     Sec.  6.1 General  Rules.  If at least one Highly  Compensated  Employee is
included in the Actual  Deferral  Percentage  test under  Section 4.2 and in the
Contribution  Percentage  test under Section 5.1, in addition to satisfaction of
the Actual Deferral  Percentage test and the  Contribution  Percentage test, the
sum of the Highly Compensated  Group's Actual Deferral  Percentage under Section
4.2 and  Contribution  Percentage under Section 5.1 may not exceed the aggregate
limit (the  "multiple  use  limitation")  of this  Article VI. The  multiple use
limitation  of this  Article VI does not  apply,  however,  unless  prior to the
application of the multiple use limitation,  the Actual Deferral  Percentage and
the Contribution Percentage of the Highly Compensated Group each exceeds 125% of
the respective percentages for the Non-Highly Compensated Group.

     Sec. 6.2  Multiple Use  Limitations.  The  multiple use  limitation  is the
greater of (i) the sum of (a) and (b) or (ii) the sum of (c) and (d), where:

        (a)     is 125% of the greater of:

                (i)  the   Actual    Deferral    Percentage   of  the Non-Highly
                Compensated  Group under Section 4.2 for the preceding Year; or

                (ii) the Contribution  Percentage of the Non-Highly  Compensated
                Group under Section 5.1 for the preceding Year; and

        (b) is equal  to two  percent  plus  the  lesser  of the  percentage  in
        subsection  (a)(i) or (a)(ii) above,  but not more than twice the lesser
        of the percentage in subsection (a)(i) or (a)(ii); or

        (c)     is equal to 125% of the lesser of:

                (i) the Actual  Deferral  Percentage of the Non-Highly
                Compensated  Group under Section 4.2 for the preceding Year; or

                (ii) the Contribution  Percentage of the Non-Highly  Compensated
                Group under Section 5.1 for the preceding Year; and

        (d) is equal  to two  percent  plus the  greater  of the  percentage  in
        subsection  (c)(i) or (c)(ii) above, but not more than twice the greater
        of the percentage in subsection (c)(i) or (c)(ii).

The  Administrator  shall determine  whether the Plan satisfies the multiple use
limitation after applying the Actual Deferral  Percentage test under Section 4.2
and the  Contribution  Percentage  test under  Section 5.1 and after  making any


                                       35
<PAGE>

corrective distributions,  the use of qualified non-elective  contributions,  or
any other  adjustments  required  or  permitted  by  Articles IV and V. If after
applying this Section 6.2, the Administrator determines that the Plan has failed
to satisfy the multiple use  limitation,  the  Administrator  shall  correct the
failure by treating the excess  amount as Excess  Matching  Contributions  under
Section 5.2. For purposes of this  Article VI,  "Highly  Compensated  Group" and
"Non-Highly  Compensated  Group" means the group of  Employees  who are eligible
Highly  Compensated  Employees and eligible  Non-Highly  Compensated  Employees,
respectively,  for the Year or  preceding  Year,  whichever  is  applicable,  as
defined in Sections 4.2 and 5.1.

     Sec. 6.3 Prospective  Reduction of  Contributions.  In the event that it is
determined by the  Administrator  at any time prior to or within a Year that the
multiple use limitation prescribed in Section 6.2 could be exceeded with respect
to such Year, then the amount of Salary Reduction  Contributions  (as determined
by the  Committee  in its  sole  and  absolute  discretion)  made on  behalf  of
Participants  who are Highly  Compensated  Employees  may be reduced in a manner
similar to the procedures described in Section 4.4.

                                   Article VII

                           ALLOCATION OF CONTRIBUTIONS

      Sec.  7.1  Establishment of Accounts. The Recordkeeper shall establish and
maintain a separate  account as a record of each  Participant's  interest in the
Trust Fund with respect to each Individual Account in which a Participant has an
interest,  including, as appropriate,  sub-accounts for the Participant's Salary
Reduction  Contributions,   his  Matching  Contributions,   his  profit  sharing
contributions,  his after-tax employee contributions to either the Penrod Thrift
Plan or the Dual  401(k)  Plan,  his  Rollover  Contributions  and his  Transfer
Contributions.  Within each such Individual  Account,  one or more  sub-accounts
shall be maintained to reflect the Participant's  investment elections among the
Investment Funds.

      Sec.  7.2  Allocation  of  Salary  Reduction  Contributions.  As  of  each
Allocation Date, but after adjustment of the Individual  Accounts as provided in
Section 9.2, the Employer  contributions  deposited  with the Trustee during the
period  since the last  Allocation  Date that  were  made  pursuant  to a salary
reduction  agreement  entered  into with a  Participant  pursuant to Section 3.1
shall be allocated by the  Recordkeeper  to the  Participant's  401(k)  Account;
provided  however,  that the amount allocated  hereunder shall be subject to the
limitations of Sections 4.1 and 4.2.

     Sec. 7.3 Allocation of Matching  Contributions and Certain Forfeitures.  As
of each  Allocation  Date, but after  adjustment of the  Individual  Accounts as
provided in Section 9.2, and after applying the limitations of Section 5.1 and


                                       36
<PAGE>

Article VI, the  Administrator  shall, to the extent  permitted by either of the
Contribution  Percentage tests of Section 5.1 and the multiple use limitation of
Article VI, direct the Recordkeeper to allocate the Matching  Contribution  made
pursuant to Section 3.2 and certain  forfeitures  under  Articles IV, V, XIV and
XV,  subject to the  application  of Section 14.5, for the period ending on such
Allocation  Date and  shall  credit  the same to the  Employer  Accounts  of all
Participants as follows:

        Each such  Participant  shall be entitled to have his  Employer  Account
        credited with that  proportion of the Employer's  Matching  Contribution
        and the forfeitures,  if any, which were designated by the Company to be
        applied to reduce Matching Contributions as provided in Section 14.5 for
        said period which the Salary Reduction  Contribution  made on his behalf
        for that period and which is considered under Section 3.2 in determining
        the Matching  Contribution  of an Employer for such period shall bear to
        the  aggregate  Salary  Reduction  Contributions  made on  behalf of all
        Participants  entitled to share in such  allocation  for that period and
        which are considered under Section 3.2 for that period.

     Sec. 7.4  Allocation of Employer  Profit Sharing  Contributions  Made Under
Section 3.3 and Certain Forfeitures.  As of the last day of each Year, but after
adjustment  of  the  Individual   Accounts  as  provided  in  Section  9.2,  the
Administrator  shall  direct the  Recordkeeper  to allocate  the profit  sharing
contribution  of the Employer,  if any, made pursuant to Section 3.3 and certain
forfeitures  under  Articles IV, V, XIV and XV,  subject to the  application  of
Section 14.5, for the Year and shall credit the same to the Employer Accounts of
all  Participants in the Plan who either (i) had their service with the Employer
terminated  by  reason  of death,  retirement  on or after age 60 or  Disability
during the Year,  or (ii) were in the service of the Employer on the last day of
the Year, as follows:

        Each such  Participant  shall be entitled to have his  Employer  Account
        credited  with  that   proportion  of  the  Employer's   profit  sharing
        contribution  made pursuant to Section 3.3 and the forfeitures,  if any,
        which were  designated  under Section 14.5 by the Company for allocation
        pursuant to this Section 7.4 for such Year which his Annual Compensation
        for such Year shall bear to the aggregate  Annual  Compensation for that
        Year of all Participants entitled to share in such allocation.

     Sec. 7.5 Allocation of Employer Qualified Non-Elective Contributions. As of
the last day of each Year, but after  adjustment of the  Individual  Accounts as
provided  in  Section   9.2,  if  an  Employer   made   qualified   non-elective
contributions  for a Year under  Section 3.4 on behalf of  Participants  who are
Non-Highly  Compensated  Employees  in order to  insure  that one of the  Actual
Deferral Percentage tests described in Section 4.2 are met for such Year or that


                                       37
<PAGE>

one of the  Contribution  Percentage  tests described in Section 5.1 are met for
such Year, such qualified  non-elective  contributions shall be allocated to the
401(k)  Accounts  of the  Non-Highly  Compensated  Employees  determined  by the
governing body of the Company in the manner  determined by the governing body of
the Company.

     Sec. 7.6 Credit of Rollover  Contributions  and Transfer  Contributions.  A
Rollover  Contribution  made by an Employee or a Transfer  Contribution  made on
behalf of an Employee  during the period since the last Allocation Date shall be
credited to his Rollover Account or Transfer Account, as the case may be.

     Sec. 7.7  Included  Individual  Accounts.  For the purposes of this Article
VII,  references to the Individual  Accounts of  Participants  shall include the
Individual  Accounts of those who die,  become  disabled,  retire,  or terminate
their services during the Year in question.

      Sec.  7.8  Special  410(b)  Allocation.  The Plan must satisfy the minimum
coverage  requirements  of  Section  410(b)  of  the  Code  each  Year.  If  the
Administrator  determines that the Plan is to satisfy Section 410(b) of the Code
for  a  Year  by  satisfying   the  ratio   percentage   test  of  Treas.   Reg.
ss.1.410(b)-2(b)(2), then notwithstanding the requirement of Section 7.4 that an
individual be in the active  service of an Employer on the last day of a Year in
order to receive an allocation of Employer profit sharing contributions, if any,
for such Year,  each such  Participant  who performed for an Affiliated  Company
more than 500 Hours of Service during the Year and was not in the active service
of an  Employer  on the last day of such Year  shall be  eligible  to  receive a
"special allocation" hereunder for such Year to the extent required for the Plan
to satisfy the ratio percentage test of Treas. Reg.  ss.1.410(b)-2(b)(2) (or its
successor).  If the  Administrator  determines  to apply this  Section  7.8, the
Administrator will suspend the accrual  requirements of Section 7.4 with respect
to certain  Participants,  beginning  first with the  Participants in the active
service of an Employer on the last day of the Year,  then the  Participants  who
have the latest  separation  from service  during the Year,  and  continuing  to
suspend in descending  order the accrual  requirements  for each Participant who
incurred an earlier  separation  from  service,  from the latest to the earliest
separation from service date, until the Plan satisfies the ratio percentage test
of Treas.  Reg.  ss.1.410(b)-2(b)(2)  for the Year. If two or more  Participants
have a separation from service on the same day, the  Administrator  will suspend
the accrual requirements for all such Participants,  irrespective of whether the
Plan can satisfy the ratio percentage test of Treas. Reg. ss.1.410(b)-2(b)(2) by
accruing benefits for fewer than all such Participants. If the Plan suspends the
accrual  requirements  for a  Participant,  that  Participant  will share in the
allocation of Employer profit sharing  contributions  and  forfeitures,  if any,
designated  pursuant to Section 14.5 for  allocation  under Section 7.4 with the


                                       38
<PAGE>

profit  sharing  contributions  without  regard to  whether  he is in the active
service of an  Employer  on the last day of the Year.  The  Administrator  shall
determine the number of Participants, selected in order of ranking, to receive a
special allocation,  if any.  Notwithstanding the above, individuals who are not
in the  active  service  of an  Employer  on the  last  day of the  Year and are
excludable  from testing under Section  410(b) of the Code shall not be eligible
for a special allocation under this Section 7.8.

                                  Article VIII

                            LIMITATION ON ALLOCATIONS

the Plan, the following provisions shall be applicable to the Plan:

        (a) If this Plan is the only plan maintained by an Employer which covers
        the  class  of  Employees  eligible  to  participate  hereunder  and the
        Participant  does not  participate  in and has never  participated  in a
        Related Plan or a welfare  benefit fund, as defined in Section 419(e) of
        the Code,  maintained by the Employer, or an individual medical account,
        as defined in Section 415(1)(2) of the Code, maintained by the Employer,
        which  provides  an Annual  Addition as defined in Section  8.2(a),  the
        Annual   Additions   which  may  be  allocated  under  this  Plan  to  a

        the Code, or (iii) an individual medical account,  as defined in Section
        415(l)(2) of the Code,  which  provides an Annual  Addition,  the Annual
        Additions  which may be  allocated  under  this Plan to a  Participant's
        Individual Account for a Limitation Year shall not exceed the lesser of:

                (i) the Maximum  Permissible  Amount,  reduced by the sum of any
                Annual Additions allocated to the Participant's accounts for the
                same Limitation Year under this Plan and such other Related Plan
                and the welfare plans described in clauses (ii) and (iii) above;
                or

                (ii) any other limitation contained in this Plan.

        (c) "Limitation Year" means a twelve-consecutive  month period ending on
        the last day of the Year. All qualified plans maintained by the Employer

        begin on a date within the  Limitation  Year in which the  amendment  is
        made.

                 Limitation Year.

        (e) "Employer" means for purposes of this Article VIII, any Employer and
        any Affiliated  Company that adopts this Plan;  provided,  however,  the
        determination under Sections 414(b) and (c) of the Code shall be made as
        if the phrase "more than 50 percent" were substituted for the phrase "at
        least 80 percent" each place it is incorporated  into Section 414(b) and
        (c) of the Code.

        (f) "Annual  Compensation" means,  notwithstanding  Section 1.5, for the
        purposes of this Article VIII, a  Participant's  earned  income,  wages,
        salaries,  fees for  professional  service  and other  amounts  received

                of an  Employee to a  simplified  employee  pension  plan to the
                extent such contributions are deductible under Section 219(b)(2)
                of the  Code,  and any  distributions  from a plan  of  deferred
                compensation  whether or not  includable  in the gross income of
                the Employee when distributed;

                (ii) amounts realized from the exercise of a non-qualified stock

                Employee),   contributions  made  by  an  Employer  for  medical
                benefits  [within the meaning of Section 401(h) or 419A(f)(2) of

                415(l)(1) or 419A(d)(2) of the Code.

        For Limitation  Years after December 31, 1991,  Annual  Compensation for
        any  Limitation  Year  is  the  Annual  Compensation  actually  paid  or
        includable in gross income during such  Limitation  Year. For Limitation
        Years after December 31, 1997, Annual Compensation shall include amounts
        contributed  by an  Employer  pursuant to a salary  reduction  agreement
        which are excludable from the Participant's  gross income under Sections

        (g) "Related Plan" means any other defined contribution plan [as defined
        in Section 415(k) of the Code]  maintained by any Employer as defined in
        Section 8.2(e).

        (h) "Defined Contribution Plan Fraction" means for any Limitation Year:

                (i) the sum of the Annual Additions to the Participant's account
                under  this Plan and his  accounts  under any  Related  Plan and
                welfare plans [as described in Section  8.1(b)(ii) and (iii)] as
                of the close of the Limitation Year,

        divided by:

                (ii) the sum of the lesser of the following  amounts  determined
                for the  Limitation  Year and for each prior Year of his service
                for an Employer:

                           (A) the  product  of 1.25,  multiplied  by the dollar
                           limitation  in effect under Section  415(c)(1)(A)  of
                           the Code for the Limitation Year [determined  without
                           regard to Section 415(c)(6) of the Code], or

                           (B) the product of 1.4, multiplied by an amount equal
                           to 25% of the Participant's  Annual  Compensation for
                           the Limitation Year.

        If the Employee was a Participant  as of the end of the first day of the
        first  Limitation Year beginning after December 31, 1986, in one or more
        defined  contribution  plans  maintained  by an  Employer  which were in
        existence on May 6, 1986, the numerator of the Defined Contribution Plan
        Fraction  will be adjusted if the sum of that  fraction  and the Defined
        Benefit Plan Fraction otherwise would exceed 1.0 under the terms of this
        Plan.  Under the  adjustment,  an amount equal to the product of (i) the
        excess of the sum of the fractions over 1.0, times (ii) the  denominator


                                       42
<PAGE>

        of this fraction,  will be permanently  subtracted from the numerator of
        this fraction.  The adjustment is calculated using the fractions as they
        would be computed  under this  Section  8.2(h) as of the end of the last
        Limitation Year beginning  before January 1, 1987, and  disregarding any
        changes in the terms and  conditions of the Plan made after May 6, 1986,
        but using the Section 415 limitations applicable to the first Limitation
        Year beginning on or after January 1, 1987. The Annual  Addition for any
        Limitation  Year  beginning   before  January  1,  1987,  shall  not  be
        recomputed to treat all Employee contributions as Annual Additions.  The
        adjustment  also will be made if at the end of the last  Limitation Year
        beginning  before January 1, 1984, the sum of the fractions  exceeds 1.0
        because of accruals or additions  that were made before the  limitations
        of this  Article  VIII became  effective  to any plans of an Employer in
        existence on July 1, 1982.  With respect to any  Limitation  Year ending
        after  December 31, 1982,  the amount taken into account  under  Section
        8.1(h)(ii)  above with respect to each  Participant  for all  Limitation
        Years  ending  before  January 1, 1983,  shall be an amount equal to the
        product of (iii) and (iv), where

                (iii) is the amount  determined under Section  8.1(h)(ii) [as in
                effect  for  the  Limitation   Year  ending  in  1982]  for  the
                Limitation Year ending in 1982, multiplied by

                (iv)       a fraction, the numerator of which is the lesser of

                           (A) $51,875, or

                           (B) 1.4, multiplied by 25% of the Annual Compensation
                           of the  Participant for the Limitation Year ending in
                           1981, and

                the denominator of which is the lesser of

                           (A) $41,500 or

                           (B) 25% of the Annual Compensation of the Participant
                           for the Limitation Year ending in 1981.

        (i)     "Defined Benefit Plan Fraction" means for any Limitation Year:

                (i) the projected  Annual Benefit of the  Participant  under the
                defined benefit plans maintained by an Employer determined as of
                the close of the Limitation Year,

        divided by:

                (ii)       the lesser of:





                                       43
<PAGE>

                           (A) the  product  of 1.25,  multiplied  by the dollar
                           limitation  in effect under Section  415(b)(1)(A)  of
                           the Code for the Limitation Year, or

                           (B) the  product  of 1.4,  multiplied  by 100% of the
                           Participant's Average Compensation.

        If the  Employee  was a  Participant  as of the  first  day of the first
        Limitation  Year  beginning  after  December  31,  1986,  in one or more
        defined benefit plans  maintained by an Employer which were in existence
        on May 6, 1986,  the  denominator of this fraction will not be less than
        125% of the sum of the  annual  benefits  under  such  plans  which  the
        Participant  had  accrued  as of the close of the last  Limitation  Year
        beginning before January 1, 1987,  disregarding any changes in the terms
        and  conditions of the Plan after May 5, 1986.  The  preceding  sentence
        applies  only  if the  defined  benefit  plans  individually  and in the
        aggregate  satisfied the requirements of Section 415 of the Code for all
        Limitation Years beginning before January 1, 1987.

        (j) "Average  Compensation" means the average Annual Compensation during
        a Participant's  high three years of service,  which period is the three
        consecutive  calendar years (or, the actual number of consecutive  years
        of employment  for those  Employees who are employed for less than three
        consecutive  years with an  Employer)  during which the Employee had the
        greatest aggregate Annual Compensation from the Employer,  including any
        adjustments under Section 415(d) of the Code.

        (k) "Annual  Benefit" means a benefit payable  annually in the form of a
        straight life annuity (with no ancillary benefits) under a plan to which
        Employees do not  contribute  and under which no Rollover  Contributions
        are made.

     Sec.  8.3  Excess  Annual  Additions.  In the event  that,  notwithstanding
Section  8.5(a)  hereof,  the  limitations  with  respect  to  Annual  Additions
prescribed  hereunder  are  exceeded  with  respect to any  Participant  for the
Limitation  Year and such Excess Amount arises as a result of the  allocation of
forfeitures,   a  reasonable   error  in  estimating  a   Participant's   Annual
Compensation  [as defined in Section 8.2(f)] for the Year, a reasonable error in
determining the amount of Salary Reduction  Contributions  that may be made by a
Participant under the limits of Section 415 of the Code, or as a result of other
facts and  circumstances  as  established  by the  Commissioner  of the Internal
Revenue  Service,  the Excess Amounts shall not be deemed an Annual  Addition in
that  Limitation  Year,  to the  extent  such  Excess  Amounts  are  treated  in
accordance with any of the following:

        (a)  Salary  Reduction  Contributions  and  earnings  thereon  shall  be
        distributed  to the  Participant  to the extent  necessary to reduce the


                                       44
<PAGE>

        Excess  Amount  as soon as  practicable  after  the  close of the  Year;
        provided,  however,  that in the event Matching  Contributions have been
        made by an Employer against any Salary Reduction  Contributions that are
        returned  to the  Participant  under  this  Section  8.3(a),  then  such
        Matching Contributions shall, to the extent necessary to satisfy Section
        401(m) of the Code, be adjusted with respect to the Participant pursuant
        to the procedures  set forth in Section 5.2. The amounts  distributed or
        forfeited are disregarded for purposes of applying Section 402(g) of the
        Code and the tests set forth in Sections 4.2 and 5.1; or

        (b) the Excess Amount attributable to the portion of the Employer profit
        sharing  contributions,  if any,  made pursuant to Section 3.3 which has
        been  allocated  to a  Participant  under  the Plan for a Year but which
        cannot be allocated to his Employer  Account  because of the  limitation
        imposed by this Section,  shall,  subject to the  limitations of Section
        8.1(a) and Section  5.1, be  allocated  and  reallocated  in the current
        Limitation  Year to the  Employer  Accounts  of the  other  Participants
        entitled to share in the Employer profit sharing  contributions for that
        Year in accordance with Section 7.4.

        (c) If an Excess Amount still exists after  application  of  subsections
        (a) and (b) hereof, the Excess Amount attributable to the portion of the
        Matching  Contribution,  if any, made pursuant to Section 3.2, which has
        been  allocated  to a  Participant  under  the Plan for a Year but which
        cannot be allocated to his Employer  Account  because of the  limitation
        imposed by this Section,  shall,  subject to the  limitations of Section
        8.1(a) and Section  5.1, be  allocated  and  reallocated  in the current
        Limitation  Year to the  Employer  Accounts  of the  other  Participants
        entitled  to  share  in the  Matching  Contributions  for  that  Year in
        accordance with Section 7.3.

        (d) Any Excess Amount that cannot be allocated will be held  unallocated
        in a suspense  account.  If a balance exists in the suspense  account in
        any Year in which an Employer makes  contributions  pursuant to Sections
        3.2,  3.3 or 3.4,  such  balance  shall be used to reduce  the  Employer
        contributions  pursuant to such  Sections  and shall be allocated in the
        same manner as such contributions  would have been allocated;  provided,
        however,  if in any such Year contributions are made pursuant to Section
        3.2 and either Section 3.3 or 3.4, or both,  such balance shall first be
        used to make the qualified non-elective contribution pursuant to Section
        3.4, then the Matching  Contribution,  if any,  pursuant to Section 3.2,
        before it is used to make the Employer profit sharing  contribution,  if
        any,  pursuant to Section 3.3. All amounts in the suspense  account must
        be allocated and  reallocated to the  Participants'  401(k)  Accounts or
        Employer  Accounts  (as  determined  by which type or types of  Employer


                                       45
<PAGE>

        contributions  the balance in the suspense  account,  if any, is used to
        reduce),  subject to the limitations of Section 8.1(a),  Section 4.2 and
        Section  5.1,  in  succeeding  Limitation  Years  before  any  qualified
        non-elective contributions,  Matching Contributions, and Employer profit
        sharing  contributions  which constitute Annual Additions may be made to
        the Plan.

        (e) in the event of termination of the Plan, the suspense  account shall
        revert to the Employer to the extent it may not then be allocated to any
        Participants' Individual Account.

        Sec. 8.4  Combined Plan Limits.

        (a) If an  Employer  maintains,  or has  ever  maintained,  one or  more
        defined  benefit plans covering an Employee who is also a Participant in
        this Plan,  the sum of the Defined  Contribution  Plan  Fraction and the
        Defined  Benefit Plan  Fraction,  cannot  exceed 1.0 for any  Limitation
        Year.  The Annual  Addition for any  Limitation  Year  beginning  before
        January  1,  1987  shall  not  be   recomputed  to  treat  all  Employee
        contributions  as  an  Annual  Addition.   If  the  Plan  satisfied  the
        applicable  requirements of Section 415 of the Code as in effect for all
        Limitation  Years  beginning  before January 1, 1987, an amount shall be
        subtracted from the numerator of the Defined  Contribution Plan Fraction
        (not  exceeding  such  numerator)  as  prescribed  by the  Secretary  of
        Treasury so that the sum of the Defined  Benefit  Plan  Fraction and the
        Defined  Contribution  Plan Fraction computed under Section 415(e)(1) of
        the Code [as  revised by this  Section  8.4(a)]  does not exceed 1.0 for
        such Limitation Year.

        (b) For  purposes  of this  Section  8.4,  Employee  contributions  to a
        defined  benefit  plan are  treated as a separate  defined  contribution
        plan. In addition,  any contributions paid or accrued after December 31,
        1985  which are  attributable  to  medical  benefits  allocated  under a
        welfare  benefit fund [as defined in Section  419(e) of the Code] during
        Years ending after December 31, 1985 to a separate  account  established
        for any  post-retirement  medical  benefits  provided  with respect to a
        Participant, who, at any time, during the Year or any preceding Year, is
        or was a Key Employee, shall be treated as Annual Additions to a defined
        contribution  plan.  Further,  all  defined  contribution  plans  of  an
        Employer  are to be treated  as one  defined  contribution  plan and all
        defined  benefit  plans of an Employer  are to be treated as one defined
        benefit plan, whether or not such plans have been terminated.

        (c) If the sum of the Defined Contribution Plan Fraction and the Defined
        Benefit Plan  Fraction  exceeds 1.0,  the sum of the  fractions  will be
        reduced to 1.0 as follows:

                (i) voluntary  nondeductible  Employee  contributions  made by a
                Participant  to the defined  benefit  plan which  constitute  an
                Annual  Addition to a defined  contribution  plan, to the extent


                                       46
<PAGE>

                they  would  reduce  the sum of the  fractions  to 1.0,  will be
                returned to the Participant;

                (ii) if  additional  reductions  are required for the sum of the
                fractions  to  equal  1.0,  voluntary   nondeductible   Employee
                contributions   made  by  a  Participant   to  this  Plan  which
                constitute  an Annual  Addition to this Plan, to the extent they
                would reduce the sum of the  fractions to 1.0,  will be returned
                to the Participant;

                (iii) if additional  reductions  are required for the sum of the
                fractions  to equal  1.0,  the Annual  Benefit of a  Participant
                under the defined  benefit  plan will be reduced  (but not below
                zero and not  below  the  amount  of the  Participant's  accrued
                benefit to date) to the extent  necessary  to prevent the sum of
                the fractions,  computed as of the close of the Limitation  Year
                from exceeding 1.0; and

                (iv) if  additional  reductions  are required for the sum of the
                fractions to equal 1.0, the reductions  will then be made to the
                Annual Additions of this Plan.

        Sec. 8.5   Special Rules.

        (a)  Notwithstanding  any  other  provision  of this  Article  VIII,  an
        Employer  shall not contribute any amount that would cause an allocation
        to the suspense account as of the date the contribution is allocated. In
        the event the  making of any  Salary  Reduction  Contribution,  Matching
        Contribution,  or Employer profit sharing or other contribution,  or any
        part thereof,  would result in the limitations set forth in this Article
        VIII being exceeded,  the Administrator  shall cause such  contributions
        not be made. If the  contribution  is made prior to the date as of which
        it is to be allocated, then such contribution shall not exceed an amount
        that would cause an  allocation  to the suspense  account if the date of
        the contribution were an Allocation Date. The Administrator  shall cause
        the Recordkeeper to maintain records which reflect the  contributions to
        be  allocated  to the  Individual  Account  of each  Participant  in any
        Limitation  Year. In the event that it is determined  prior to or within
        any Limitation Year that the foregoing  limitations would be exceeded if
        the full amount of contributions otherwise allocable would be allocated,
        the Annual  Additions to this Plan for the  remainder of the  Limitation
        Year shall be adjusted  by  reducing  (i) first,  any  unmatched  Salary
        Reduction  Contributions,  (ii)  second,  any  Employer  profit  sharing
        contributions   and  (iii)   third,   any   matched   Salary   Reduction
        Contributions and a corresponding  share of Matching  Contributions but,
        in each case, only to the extent necessary to satisfy the limitations.





                                       47
<PAGE>

        (b) If the Annual Additions with respect to the Participant  under other
        Related  Plans and welfare  plans  described in Section  8.1(b)(ii)  and
        (iii) are less than the  Maximum  Permissible  Amount  and the  Employer
        contribution  that  otherwise  would be  contributed or allocated to the
        Participants'  Individual Account under this Plan would cause the Annual
        Additions for the  Limitation  Year to exceed the  limitation of Section
        8.1(b),  the amount contributed or allocated will be reduced so that the
        Annual Additions under all such plans for the Limitation Year will equal
        the Maximum  Permissible Amount. If the Annual Additions with respect to
        the  Participant  under the Related Plans and welfare plans described in
        Section  8.1(b)(ii)  and (iii) in the  aggregate are equal to or greater
        than the Maximum  Permissible  Amount,  no amount will be contributed or
        allocated to the  Participants'  Individual  Account under this Plan for
        the Limitation Year. If a Participant's Annual Additions under this Plan
        and all Related  Plans result in an Excess  Amount,  such Excess  Amount
        shall be deemed to consist of the amounts  last  allocated,  except that
        Annual  Additions  attributable  to a welfare plan  described in Section
        8.1(b)(ii)  and  (iii)  will be  deemed  to have  been  allocated  first
        regardless of the actual allocation date.

        (c) If an Excess Amount was allocated to a Participant  on an allocation
        date of a Related Plan,  the Excess Amount  attributed to this Plan will
        be the product of:

                (i) the total Excess Amount allocated as of such date [including
                any  amount  which  would  have  been   allocated  but  for  the
                limitations of Section 8.1(b)],

        multiplied by:

                (ii)       the ratio of:

                           (A) the amount allocated to the Participant as of
                               such date under this Plan,

                divided by:

                           (B) the total amount  allocated as of such date under
                           this Plan and all Related Plans  [determined  without
                           regard to Section 8.1(b)].

        (d)  Prior  to the  determination  of the  Participant's  actual  Annual
        Compensation for a Limitation Year, the Maximum  Permissible  Amount may
        be  determined  on the  basis  of  the  Participant's  estimated  Annual
        Compensation   for  such   Limitation   Year.   Such  estimated   Annual
        Compensation  shall be  determined  on a  reasonable  basis and shall be
        uniformly  determined  for  all  Participants  similarly  situated.  Any


                                       48
<PAGE>

        Employer  contributions  (including  allocation of forfeitures) based on
        estimated  Annual  Compensation  shall be reduced by any Excess  Amounts
        carried over from prior Years.

        (e)  As  soon  as is  administratively  feasible  after  the  end of the
        Limitation Year, the Maximum Permissible Amount for such Limitation Year
        shall be  determined  on the basis of the  Participant's  actual  Annual
        Compensation for such Limitation Year.

                                   Article IX

                        ADJUSTMENT OF INDIVIDUAL ACCOUNTS

     Sec. 9.1 Trust Fund Valuation. The value of each Investment Fund and of the
Trust Fund shall be  determined  by the  Trustee as of the close of  business on
each Valuation Date, or as soon thereafter as practicable, and shall be the fair
market value of all securities or other  property held in the Investment  Funds,
plus cash and the fair market value of other assets held by the Trust Fund, with
equitable adjustments for pending trades.

     While it is contemplated  that the Trust Fund will be valued by the Trustee
and  allocations  made only on the  Valuation  Date, at any time that the Plan's
valuations  are not  performed on a daily basis,  should it be necessary to make
distributions  under the provisions hereof and the Administrator,  in good faith
determines  that,  because of (i) an  extraordinary  change in general  economic
conditions,  (ii) the occurrence of some casualty materially affecting the value
of the  Trust  Fund or a  substantial  part  thereof,  or  (iii)  a  significant
fluctuation  in the value of the Trust Fund has occurred  since the  immediately
preceding  Valuation Date, the  Administrator  may, in its sole  discretion,  to
prevent the payee from receiving a  substantially  greater or lesser amount than
what he would be entitled to, based on current  values,  cause a revaluation  of
the Trust Fund to be made and a reallocation of the interests  therein as of the
date the  payee's  right of  distribution  becomes  fixed.  The  Administrator's
determination to make such special valuation and the valuation of the Trust Fund
as determined by the Trustee shall be conclusive and binding on all persons ever
interested hereunder.

     If the  Administrator  in good faith  determines  that certain  expenses of
administration  paid by the Trustee during the Year under  consideration are not
general,   ordinary  and  usual  and  should  not  equitably  be  borne  by  all
Participants, Former Participants and Beneficiaries, but should be borne only by
one or more  Participants,  Former  Participants or  Beneficiaries,  for whom or
because of whom such  specific  expenses  were  incurred,  the net  earnings and
adjustments  in value of the  Individual  Accounts  shall  be  increased  by the
amounts of such expenses, and the Administrator shall make suitable adjustments

by debiting the particular Individual Account or Individual Accounts of such one
or more Participants,  Former Participants or Beneficiaries;  provided, however,
that any such  adjustment  must be  nondiscriminatory  and  consistent  with the
provisions of Section 401(a) of the Code.

      Sec.   9.2   Adjustments   to  Participant's   and  Former   Participant's
Individual  Accounts.  Each Investment Fund shall be valued at fair market value
as of the close of business on each  Valuation  Date.  Except as provided  below
with  respect  to  Fund  5  (as  defined  in  Section  1.24),  the  value  of  a
Participant's or Former  Participant's  Individual  Account  (including for this
purpose,  the separate value of the  sub-accounts of a  Participant's  or Former
Participant's  Individual  Account,  i.e.,  his  Employer  Account,  his  401(k)
Account, his Prior Plan Account, his Reinstatement Account, if any, his Rollover
Account,  if any, his Transfer Account, if any, and his Savings Account, if any)
held in an investment fund  maintained  hereunder shall be determined as of each
Valuation Date by:

        (a)  First,  allocating  the Net Gains or Losses of such fund  since the
        preceding Valuation Date to the Participant's  Individual Account within
        such fund in the same ratio as the value of the  Participant's or Former
        Participant's  Individual Account in such fund (as adjusted below) bears
        to the  aggregate  value of all  Individual  Accounts  in such  fund (as
        adjusted below).

        An  Individual  Account  shall be  adjusted  on the  Valuation  Date for
        purposes of allocating Net Gains or Losses under the above  paragraph by
        taking the value of such  Individual  Account as of the prior  Valuation
        Date and (i) adding  thereto (A) all  contributions  or loan  repayments
        designated  for  investment in such fund which were made with respect to
        the immediately  prior valuation period but were received by the Trustee
        after the prior  Valuation  Date,  plus (B) any transfers from any other
        Investment Fund under the Plan to the Participant's  Individual  Account
        within this fund that were made after the prior  Valuation Date and were
        effective as of the first day after such prior  Valuation  Date and (ii)
        deducting  therefrom (A) any transfers to any other  Investment  Fund or
        Funds under the Plan from the  Participant's  Individual  Account within
        this  fund  that were  made  after  the  prior  Valuation  Date and were
        effective  as of the first day after such prior  Valuation  Date and any
        Participant  loans,  withdrawals,  distributions or forfeitures from the
        Individual  Account  made  after,  but  effective  as of, the  preceding
        Valuation Date.

        (b) Second,  crediting the  contributions and loan repayments made by or
        on behalf of the Participant with respect to the valuation period ending
        on the current Valuation Date and designated for investment in such fund
        and any transfers from the other  Investment Funds under the Plan to the
        Participant's  Individual  Account  within  this  fund  made  since  the
        preceding Valuation Date.




                                       50

        (c) Last,  deducting any transfers to the other  Investment  Funds under
        the Plan from the  Participant's  Individual  Account  maintained within
        this  fund  and any  loans,  withdrawals  and  distributions  (including
        forfeitures)  from his Individual  Account  maintained  within this fund
        made since the preceding Valuation Date.

        An  Individual  Account  invested in Fund 5 shall have  allocated  to it
whole number of shares of Company Stock and cash to the extent share(s) have not
been acquired for such fund and the earnings, losses and distributions on shares
held in an Individual  Account  invested in Fund 5 shall be allocated  solely to
that Individual Account.

        For the purpose of this  Section,  "Net Gains or Losses"  shall mean the
fair market value of the assets of the  Investment  Fund (if invested in a group
insurance  investment  contract,  such value being determined in accordance with
the terms of the  contract) as of the current  Valuation  Date,  over such value
which was utilized for the prior  Valuation  Date,  less the sum of any deposits
plus the sum of any loans,  withdrawals,  distributions or other deductions,  if
any, made to pay any expenses  incurred  with respect to the  operations of this
fund. The initial  Valuation  Date for an Investment  Fund shall be the date the
funds are first invested in such Investment Fund.

                                    Article X

                               INDIVIDUAL ACCOUNTS

     Sec. 10.1    Participant Interest in Individual Accounts.  Each Participant
and Former Participant shall at all times have a nonforfeitable  interest in his
401(k) Account,  Prior Plan Account,  Savings  Account,  Reinstatement  Account,
Rollover  Account and  Transfer  Account,  but he shall have no right,  title or
interest  in the  balance  of  his  Individual  Account  except  as  hereinafter
provided. In no event shall his nonforfeitable interest exceed the amount to the
credit of his Individual Account as the same may be adjusted from time to time.

     Sec.  10.2  Annual  Statement  to  Participant.   At  least  annually,  the
Administrator shall advise each Participant,  Former Participant and Beneficiary
for whom an Individual  Account is held  hereunder of the then fair market value
of such Individual Account.

                                   Article XI

                                   RETIREMENT

   Sec.  11.2  Benefits  on Normal  Retirement.  Upon the  retirement  of a
Participant  on or after his  Normal  Retirement  Date,  his  entire  Individual
Account shall be held for his benefit.  Said Participant  shall receive payments
from his Individual  Account in accordance with Article XV hereof  commencing as
of the Valuation Date  immediately  following the date of his retirement that he
determines in his advance written election filed with the Administrator.

     Sec. 11.3 Commencement of Benefits.  Notwithstanding any other provision of
this Plan to the contrary,  a Participant  shall begin  receiving  distributions
from the Plan,  as provided in Article XV, by his  Required  Beginning  Date [as
defined in Section 15.4(j)(ii)], whether or not he actually retires.

     Sec.  11.4  Final  Contribution  After  Distribution  of  Benefits.   If  a
Participant who has already  received a distribution  of his Individual  Account
under this Article is entitled to an  allocation of an Employer  profit  sharing
contribution  under Section 7.4 or a qualified  non-elective  contribution under
Section 7.5 for the Year in which such distribution was made, such contributions
shall  be  paid to the  Participant  as  soon  as  administratively  practicable
following the completion of the allocations under Article VII for such Year.

                                   Article XII

     Sec. 12.1 Benefits on Death.  Upon the death of a Participant  who is in
the service of an Employer,  his entire Individual Account shall be held for the
benefit of his Beneficiary.  Upon the death of a Participant  whose service with
an Employer  has  terminated,  his  nonforfeitable  interest  (determined  under
Section 14.2) in his  Individual  Account which has not been  distributed at the
time of his death  under  Articles  XI-XIV  shall be held for the benefit of his
Beneficiary.  His Beneficiary shall receive payments from his Individual Account
in  accordance  with  Article  XV hereof  commencing  as of the  Valuation  Date
immediately  following the date of the Participant's  death that the Beneficiary
determines in his advance written election filed with the Administrator.

     Sec. 12.2 Final Contribution  After Payment of Benefits.  If the Individual
Account of a deceased  Participant  whose  Beneficiary  has  already  received a
distribution  of the  Participant's  Individual  Account  under this  Article is
entitled to an  allocation  of an Employer  profit  sharing  contribution  under
Section 7.4 or a qualified  non-elective  contribution under Section 7.5 for the
Year in which such  distribution was made, such  contributions  shall be paid to
the Beneficiary as soon as administratively practicable following the completion
of the allocations under Article VII for such Year.

                                  Article XIII

                                   DISABILITY

     Sec.  13.1     Benefits on  Disability.  In the event of  termination  of a
Participant's employment due to Disability,  his entire Individual Account shall
be held for his benefit. If the balance of the Participant's  Individual Account

Account in accordance with Article XV hereof commencing as of the Valuation Date
immediately  following  the date of his  Disability  that he  determines  in his
advance  written  election filed with the  Administrator.  If the balance of the
Participant's Individual Account does not exceed $3,500, the Administrator shall
direct  the  Trustee  to  distribute  the  entire  Individual   Account  to  the
Participant  in a  single  lump  sum  distribution  as soon as  administratively
practicable  after  the end of the  calendar  quarter  in which  the date of his
Disability  occurs  or prior  to such  date if so  directed  in  writing  by the
Participant.  Effective  January 1, 1998, the dollar amount in this Section 13.1
shall automatically be adjusted to $5,000.

     Sec. 13.2 Final  Contribution  After Payment of Benefits.  If a Participant
who has already  received a distribution  of his  Individual  Account under this
Article is entitled to an allocation of an Employer profit sharing  contribution
under Section 7.4 or a qualified non-elective contribution under Section 7.5 for
the Year in which the distribution was made, such contributions shall be paid to
the Participant as soon as administratively practicable following the completion
of the allocations under Article VII for such Year.

                                   Article XIV

                              TERMINATION BENEFITS

     Sec.  14.1  Termination  Other  than by  Reason  of  Death,  Disability  or
Retirement. If a Participant terminates his employment for any reason other than
retirement on or after age 60, death or Disability,  such  Participant  shall be
entitled to such  benefits as are  hereinafter  provided in Section  14.2 at the
time specified in Section 14.3.

     Sec.  14.2   Vested  Interest.  A  Participant  to whom the  provisions of
Section 14.1 are applicable  shall be entitled to receive the entire amount then
standing  to his  credit in his 401(k)  Account,  his Prior  Plan  Account,  his
Savings  Account,  his  Reinstatement  Account,  his  Rollover  Account  and his
Transfer  Account.  In addition,  he shall be entitled (as a vested interest) to
receive a percentage  of the then balance to his credit in his Employer  Account
determined in accordance with the following schedule:


                                       53
<PAGE>
                Period of Service in Years                  Vested Interest

                Less than 2                                          0%
                2 but less than 3                                   20%
                3 but less than 4                                   40%
                4 but less than 5                                   60%
                5 but less than 6                                   80%
                6 or more                                          100%

If a Participant  incurs a forfeiture from his Employer Account pursuant to this
Article  XIV  and  the  forfeiture  is  subsequently   reinstated   through  the
Participant's   timely  repayment  or  deemed  repayment  of  the  distribution,
thereafter the vested portion of his restored Employer Account shall, until such
time as he may become  100%  vested  therein or such  Employer  Account is again
forfeited,  be an amount  ("X")  determined  by the  formula:  X=P(AB+D)-D.  For
purposes of applying  this formula:  P is the vested  percentage at the relevant
time; AB is the account balance at the relevant time; and D is the amount of the
prior distribution (or deemed distribution).

        Sec.  14.3  Time  of  Distribution.  If  a  Participant  terminates  his
employment  for a reason other than  retirement,  death or  Disability,  and the
value of the vested portion of his Individual  Account exceeds $3,500  (adjusted
as provided below), then the Administrator  shall direct the Trustee,  with such
Participant's  written consent, to distribute to such Participant the portion of
his Individual  Account to which he is entitled under Section 14.2 in accordance
with Article XV hereof as soon as  administratively  practicable after the later
of (i) the  Participant's  termination  of employment or (ii) the earlier of (A)
the Valuation Date immediately following the date determined by such Participant
in his advance written election filed with the  Administrator or (B) the date on
which such Participant attains age 62 or his earlier death occurs, but not later
than the time specified in Section 15.4. If such Participant does not consent to
an early  distribution,  the vested  portion  of his  Individual  Account  shall
continue  to be  invested  in the  Investment  Funds  or Funds  selected  by the
Participant pursuant to his current investment direction.

        However, if the vested balance of a terminated  Participant's Individual
Account does not exceed $3,500,  the  Administrator  shall direct the Trustee to
distribute the vested balance of the Individual Account to such Participant in a
single lump sum distribution as soon as  administratively  practicable after the
end of the calendar quarter in which the Participant's termination of employment
occurs or prior to such  date if so  directed  in  writing  by the  Participant.
Effective  January  1,  1998,  the  dollar  amount in this  Section  14.3  shall
automatically  be adjusted to $5,000.  The balance to the credit of a terminated
Participant  in his Employer  Account  which is not vested under the schedule in
Section 14.2, if not previously forfeited,  shall be forfeited as of the earlier


                                       54
<PAGE>

of  (i)  the  date  his  entire  vested  Individual  Account  balance  has  been
distributed  under  Article  XV or (ii) the  last day of the Year in which  such
Participant  incurs  a  60-consecutive   month  Period  of  Severance.   If  the
Participant is not entitled to any portion of his Individual  Account,  he shall
be deemed to have received a  distribution  and shall forfeit the balance of his
Employer Account on the date of his termination of service. The forfeited amount
under this  Section  14.3 shall remain in the Trust Fund and shall be applied as
provided in Section 14.5. If a Former Participant is reemployed by an Affiliated
Company without incurring a 60-consecutive  month Period of Severance,  he shall
have the right to restore in full the portion of his Employer  Account which was
forfeited  hereunder  upon  repayment  to the  Plan of the  full  amount  of the
distribution  from such account.  Such repayment must be made not later than the
earlier of the fifth  anniversary of his return to employment or the last day of
the Year in which  the  Participant  incurs a  60-consecutive  month  Period  of
Severance after the date of his distribution.  The Participant's  repayment,  if
any, shall be held in the Participant's Reinstatement Account and the reinstated
forfeiture  shall  be  held  in  the  Participant's  Employer  Account.  If  the
Participant  resumes active  employment with an Affiliated  Company and does not
repay a prior distribution prior to the time specified above, the portion of his
Employer  Account which was forfeited  hereunder  shall not be restored.  If the
Participant  was deemed to receive a  distribution  as provided in this Section,
the forfeited portion of his Employer Account shall be automatically  reinstated
upon his reemployment.  If currently unallocated forfeitures are not adequate to
effect the  restoration,  the Company or the Affiliated  Company shall make such
additional  contribution  to the Plan as is necessary  to restore the  forfeited
portion of his Employer Account.

        Sec.   14.4   Forfeiture   and  Return  to  Service  Prior  to  Complete
Distribution. After a 60-consecutive month Period of Severance, a Participant to
whom this  Article XIV is  applicable,  other than a  Participant  described  in
Section 14.3,  shall forfeit that portion of the amount of his Employer  Account
to which he is not entitled  under  Section  14.2 and the amount thus  forfeited
shall remain in the Trust Fund and shall be applied as provided in Section 14.5.
The amount forfeited by a Participant hereunder shall be charged to his Employer
Account on the last day of the Year as of which he shall incur a  60-consecutive
month  Period of  Severance.  If the  Participant  returns to the service of the
Employer after a 60-consecutive  month Period of Severance,  but before the full
payment  of  his  Individual   Account,   Employer   contributions   after  such
60-consecutive  month  Period of  Severance  shall be  allocated  to an Employer
Account  established  on behalf of such  Participant  which is separate from the
Individual Account of such Participant to which is allocated his account balance
attributable to service prior to the 60-consecutive month Period of Severance.

        Sec. 14.5  Application  of  Forfeitures.  The  forfeitures  occurring as
provided  in  Articles  IV,  V, XIV and XV shall  first be used to  restore  the


                                       55
<PAGE>

account of a Former  Participant  who has been  located as  provided  in Section
15.9. If additional  forfeitures  remain after full  restorations  under Section
15.9,  then remaining  forfeitures  shall be used to restore  accounts of Former
Participants  under Section 14.3. If additional  forfeitures  remain thereafter,
the  forfeitures  for a Year may be  designated by the Company (i) to be used to
reduce the  Matching  Contribution  of any  Employer  under  Section 3.2 and for
allocation   under  Section  7.3  as  of  any  Allocation  Date  as  a  Matching
Contribution  or (ii)  for  allocation  under  Section  7.4 in  addition  to the
Employer profit sharing  contribution,  if any, made for such Year under Section
3.3.

                                   Article XV

                          DISTRIBUTIONS AND WITHDRAWALS

     Sec. 15.1 Payment Options. Whenever a Participant,  Former Participant,  or
Beneficiary is entitled to receive benefits hereunder as provided in Articles XI
to XIV, inclusive, the Administrator shall direct the Trustee, if so directed in
writing  signed by the  Participant,  to pay such benefits in any one or more of
the following ways:

        (a) A lump sum, payable in cash (except that any distribution  from Fund
        5 shall be made in whole shares of Company Stock,  with the value of any
        fractional share allocated  thereto being distributed in cash unless the
        Participant  (or  Beneficiary)  elects  for  all or a  portion  of  such
        distribution  to be made in cash),  at the fair  market  value as of the
        Valuation Date immediately  preceding the date of distribution  plus the
        actual amount of any contributions made by the Participant subsequent to
        such Valuation Date, provided that a life annuity may not be a part of a
        lump sum distribution;

        (b) Periodic  installments  not more  frequently  than monthly over such
        period of time as the Participant shall determine in accordance with the
        provisions of Section 15.4; provided, that in no event may the period of
        installment  payments  exceed  the  lesser  of (i) ten years or (ii) the
        joint  life  expectancy  of  the  Participant  whose  account  is  being
        distributed and his Beneficiary.  If benefits are payable over the joint
        life  expectancy of the  Participant  and his  Beneficiary,  the present
        value of the payments to be made over the Participant's  life expectancy
        must be more than 50% of the  present  value of the  payments to be made
        over the Participant's and his Beneficiary's  joint life expectancy.  If
        benefits  are  payable  with  respect  to  the  life  expectancy  of the
        Participant and his spouse, such life expectancy may be redetermined but
        not  more  frequently  than  annually.  If  distributions  are  made  in
        installments,  the amount of the monthly  installment  shall be adjusted
        each year by determining  the value of the Individual  Account as of the


                                       56
<PAGE>

        end of the preceding Year and dividing such amount by the remaining life
        expectancy.  If the Trust Fund is adjusted to reflect the  allocation of
        gains and losses after the time of the  adjustment  in the amount of the
        monthly  installment  payments due to the change in the life expectancy,
        the  remaining  monthly  payments  for such Year  shall be  adjusted  to
        reflect any increase or decrease in the value of the Individual Account.
        Any adjustment which would decrease the amount of the remaining  monthly
        payments shall be mutually agreed to by the affected Participant and the
        Administrator; or

        (c) by  electing a direct  rollover to an  eligible  retirement  plan as
        described in Section 402(c)(8)(B) of the Code pursuant to the provisions
        of Section 15.11.

        Sec. 15.2  Determination  of Form and Timing of Payment.  In determining
which method or methods permitted in Section 15.1 shall be used in any case, the
Administrator shall follow the directions of the Participant, Former Participant
or Beneficiary involved. Notwithstanding the foregoing or any other provision of
the Plan to the contrary, if the vested balance of the Participant's  Individual
Account  does not exceed  $3,500,  then subject to the  requirements  of Section
15.11, the  Administrator  shall direct the Trustee to pay the vested balance to
the  Participant,  Former  Participant or Beneficiary,  as the case may be, in a
single lump sum  distribution.  Effective  January 1, 1998, the dollar amount in
the preceding sentence shall  automatically be adjusted to $5,000. If the vested
balance of the  Participant's  Individual  Account could be  distributed  to the
Participant  before  the  Participant  attains  (or would have  attained  if not
deceased) age 62, the Participant must consent in writing to any distribution of
such  Individual  Account.  The consent  must be obtained in writing  within the
90-day  period  prior  to  the  date  benefit  payments  are  to  commence.  The
Administrator   shall  notify  the   Participant  of  the  right  to  defer  any
distribution  until age 62. Such notification  shall be provided no less than 30
days and no more than 90 days before benefit  payments are to commence and shall
include a general  description of the material  features,  and an explanation of
the relative  values of, the forms of benefit  available under Section 15.1 in a
manner that would satisfy the notice  requirements  of Section  417(a)(3) of the
Code and a description of his direct rollover  rights under Section 15.11.  Such
distribution  may  commence  less than 30 days after the notice  required  under
Treas.  Reg.ss.1.411(a)-11(c)  is  given,  provided  that (i) the  Administrator
clearly informs the Participant  that the Participant has a right to a period of
at least 30 days after  receiving the notice to consider the decision of whether
or not to elect a distribution  (and, if applicable,  a particular  distribution
option) and (ii) the  Participant,  after  receiving  the notice,  affirmatively
elects a  distribution.  The consent of the  Participant  is not required to the
extent that a distribution is required to satisfy  Section  401(a)(9) or Section
415 of the Code.

                                       57
<PAGE>

     Sec. 15.3    Minority or Disability of Distributee.  During the minority or
disability of a person entitled to receive benefits  hereunder,  the Trustee may
make payments due such person  directly to him or to his spouse or a relative or
to any  individual  or  institution  having  custody of such person.  Neither an
Employer, the Committee, the Administrator,  the Named Fiduciary nor the Trustee
shall be  required  to see to the  application  of any  payments so made and the
receipt of the payee  (including the  endorsement of a check or checks) shall be
conclusive as to all interested parties.

     Sec. 15.4  Time of Payment and Payment on Death.  Notwithstanding any other
provisions  of the Plan,  the  following  provisions  shall be applicable to the
Plan:

        (a) Payment of benefits shall begin,  unless the  Participant  otherwise
        elects,  not  later  than the 60th day after the last day of the Year in
        which the latest of the following events occurs:

                (i)  the Participant reaches the earlier of age 65 or his Norma
                 Retirement Date;

                (ii) the tenth  anniversary of the date on which the Participant
                commenced  participation in the Plan occurs,  but not later than
                the April 1 of the calendar year  following the calendar year in
                which the Participant attains age 70 1/2; or

                (iii) the Participant  terminates his service with the Employer,
                but in no event  later  than the  April 1 of the  calendar  year
                following the calendar year in which the Participant attains age
                70 1/2 if such Participant is a five percent owner as defined in
                Section  15.4(j)(ii)  with  respect  to the Year  ending  in the
                calendar year in which he attains age 70 1/2.

        If the Participant fails to consent to a distribution at a time when any
        part of the balance of the Individual Account could be distributed prior
        to the  Participant's  Normal  Retirement  Date or age 62, such  failure
        shall be deemed to be an  election to defer  commencement  of payment of
        any benefit under this Section 15.4(a).

        (b) All distributions required under this Article XV shall be determined
        and  made in  accordance  with  Section  401(a)(9)  of the  Code and the
        Treasury  regulations  thereunder,  including  the minimum  distribution
        incidental benefit requirements of Treas. Reg. ss.1.401(a)(9)-2.

        (c) An election of a Participant  to defer receipt of benefits  shall be
        made by submitting to the  Administrator a written  statement  signed by
        the  Participant,  describing  the  benefits  and the date on which  the


                                       58
<PAGE>

        Participant  requests that the payments commence;  provided,  however, a
        Participant may not elect to defer receipt or commencement of receipt of
        benefits beyond his Required Beginning Date.

        (d) If the  Individual  Account of a  Participant  is to be  distributed
        other  than in a lump sum  under  Section  15.1(a)  after  the  Required
        Beginning Date, the following minimum distribution rules shall apply:

                (i) As of the first Distribution Calendar Year, distributions if
                not made in a single lump sum under Section 15.1(a), may only be
                made  over  one  of  the  following   periods  (or  combinations
                thereof):  (A) the life of the Participant;  (B) the life of the
                Participant and a Designated  Beneficiary;  (C) a period certain
                not extending beyond the Life Expectancy of the Participant;  or
                (D) a period  certain  not  extending  beyond the Joint and Last
                Survivor   Expectancy  of  the   Participant  and  a  Designated
                Beneficiary;

                (ii) If a Participant's Benefit is to be distributed over either
                (A) a period not  extending  beyond the Life  Expectancy  of the
                Participant  or the Joint and Last  Survivor  Expectancy  of the
                Participant and  the Participant's Designated Beneficiary or (B)
                a  period  not  extending  beyond  the  Life  Expectancy  of the
                Designated  Beneficiary,  the amount  required to be distributed
                for each calendar  year,  beginning with  distributions  for the
                first  Distribution  Calendar  Year,  must at  least  equal  the
                quotient obtained by dividing the  Participant's  Benefit by the
                Applicable Life Expectancy;

                (iii) The amount to be  distributed  each year,  beginning  with
                distributions for the first Distribution Calendar Year shall not
                be less than the quotient obtained by dividing the Participant's
                Benefit by the lesser of (A) the Applicable  Life  Expectancy or
                (B) the  applicable  divisor,  in the  event  the  Participant's
                spouse is not the Designated  Beneficiary,  determined  from the
                tables  set  forth in Q & A-4 of  Section  1.401(a)(9)-2  of the
                Treasury  regulations.   Distributions  after  the  death  of  a
                Participant  shall  be  distributed  using the  Applicable  Life
                Expectancy in Section  15.4(d)(ii) above as the relevant divisor
                without  regard  to  Section   1.401(a)(9)-2   of  the  Treasury
                regulations; and

                (iv) The minimum  distribution  required  for the  Participant's
                First  Distribution  Calendar Year must be made on or before the
                Participant's  Required Beginning Date. The minimum distribution
                for other calendar years, including the minimum distribution for
                the  Distribution  Calendar  Year  in  which  the  Participant's


                                       59
<PAGE>

                Required  Beginning  Date  occurs,  must be  made  on or  before
                December 31 of that Distribution Calendar Year.

        (e) If distribution of benefits to a Participant has begun under Section
        15.1 and the Participant dies before his entire  Individual  Account has
        been  distributed  to him, the remaining  portion of such  Participant's
        Individual  Account must be distributed  to his  Beneficiary at least as
        rapidly as under the method of  distributions  being used under  Section
        15.1 as of the date of his death.

        (f) If a Participant dies before the distribution of benefits to him has
        begun under Section 15.1,  distribution to his Beneficiary of his entire
        Individual Account must be completed by December 31 of the calendar year
        containing the fifth anniversary of the death of such  Participant.  The
        provisions of this Section 15.4(f) shall not apply to the portion of the
        Participant's Individual Account which is payable:

                (i) to a  Designated  Beneficiary  other than the  Participant's
                surviving spouse under Section 15.1 of  distributions  made over
                the  life or over a period  certain  not  greater  than the Life
                Expectancy of the Designated Beneficiary commencing on or before
                December  31 of the  calendar  year  immediately  following  the
                calendar year in which the Participant died; or

                (ii) under Section 15.1 to a Designated  Beneficiary  who is the
                surviving spouse of the Participant if the  distributions  begin
                at least by the  later of (A) the  December  31 of the  calendar
                year  immediately  following  the  calendar  year in  which  the
                Participant died and (B) the December 31 of the calendar year in
                which the Participant would have attained age 70 1/2.

        If the  Participant  has not made an election  pursuant to this  Section
        15.4(f)  by  the  time  of  his  death,  the  Participant's   Designated
        Beneficiary  must  elect the  method of  distribution  no later than the
        earlier of (1) December 31 of the calendar  year in which  distributions
        would be required to begin under this Section  15.4(f),  or (2) December
        31 of the calendar year which contains the fifth anniversary of the date
        of  death  of the  Participant.  If the  Participant  has no  Designated
        Beneficiary, or if the Designated Beneficiary does not elect a method of
        distribution,   distribution  of  the  Participant's  entire  Individual
        Account must be completed by December 31 of the calendar year containing
        the fifth anniversary of the Participant's death.

        (g) If a portion of the Participant's  Individual  Account is payable to
        the   Participant's   surviving  spouse  and  such  spouse  dies  before
        distributions  to such spouse begin,  the spouse shall be treated as the


                                       60
<PAGE>

        Participant  under Section  15.4(f) with the exception of the provisions
        of subsection (ii) thereof.

        (h) Any portion of a  Participant's  Individual  Account paid to a child
        shall be treated as if such  portion has been paid to the  Participant's
        surviving  spouse if such portion will become  payable to the  surviving
        spouse upon the date the child  reaches  majority  (or other  designated
        event  permitted  under  regulations  prescribed by the Secretary of the
        Treasury).

        (i) Distribution of a Participant's  Individual Account is considered to
        begin  on the  Participant's  Required  Beginning  Date or,  if  Section
        15.4(g) is applicable, the date distribution is required to begin to the
        surviving spouse pursuant to Section 15.4(f)(ii).

        (j)     Definitions:

                (i)  Designated  Beneficiary is the individual who is designated
                as the  Beneficiary  under the Plan in  accordance  with Section
                401(a)(9) of the Code and the Treasury regulations thereunder.

                (ii)  The  Required  Beginning  Date of a  Participant  shall be
                determined as follows:

                           (A) If the Participant is not a five percent owner of
                           the  Company  (as  defined   below),   his   Required
                           Beginning  Date is the April 1 of the  calendar  year
                           following the later of (1) the calendar year in which
                           the  Participant  attains  age  70  1/2  or  (2)  the
                           calendar year in which the Participant retires; or

                           (B) If the Participant is a five percent owner of the
                           Company (as defined  below),  his Required  Beginning
                           Date is the April 1 of the  calendar  year  following
                           the calendar  year in which the  Participant  attains
                           age 70 1/2.

                A Participant who is not a five percent owner of the Company and
                who commenced  receiving benefit payments from the Plan after he
                attained age 70 1/2 under the rules applicable to the Plan prior
                to January  1, 1997 may elect to stop  receiving  such  payments
                until his Required Beginning Date under this subsection (j)(ii).

                A Participant  is treated as a five percent owner of the Company
                for purposes of this Section  15.4(j)(ii) if such Participant is
                a five  percent  owner as defined in Section  416(i) of the Code
                (determined  in  accordance  with  Section  416 of the  Code but
                without  regard to  whether  the Plan is top  heavy) at any time
                during the Year ending with or within the calendar year in which
                such  owner  attains  age 66 1/2 or any  subsequent  Year.  Once


                                       61
<PAGE>

                distributions  have  begun to a five  percent  owner  after  his
                Required  Beginning  Date, they must continue to be distributed,
                even if the  Participant  ceases to be a five percent owner in a
                subsequent Year.

                (iii)  Applicable Life Expectancy  means the Life Expectancy (or
                Joint  and Last  Survivor  Expectancy)  computed  (by use of the
                expected  return  multiples in Tables V and VI of Section 1.72-9
                of the  Treasury  regulations)  using  the  attained  age of the
                Participant (or Designated  Beneficiary) as of the Participant's
                (or  Designated   Beneficiary's)   birthday  in  the  applicable
                calendar  year reduced by one for each  calendar  year which has
                elapsed since the date Life Expectancy was first calculated.  If
                the Life Expectancy is being  recalculated,  the Applicable Life
                Expectancy shall be the Life Expectancy as so recalculated.  The
                Life   Expectancy  of  a  nonspouse   beneficiary   may  not  be
                recalculated.  The method of  calculating  the  Applicable  Life
                Expectancy is irrevocable after the Required Beginning Date. The
                Participant may elect whether the Applicable Life Expectancy (to
                be used  in  calculating  distributions  commencing  during  his
                lifetime) is his Life  Expectancy or the Joint and Last Survivor
                Expectancy  of him and his  Designated  Beneficiary  and whether
                such Life Expectancy (or Joint and Last Survivor Expectancy) are
                to be recalculated. If the Participant fails to elect before the
                Required Beginning Date, the Applicable Life Expectancy shall be
                the Life Expectancy of the Participant  (irrespective of whether
                the  Participant  has a  Designated  Beneficiary)  and such Life
                Expectancy shall be recalculated.  The applicable  calendar year
                shall  be the  first  Distribution  Calendar  Year,  and if Life
                Expectancy is being recalculated, such succeeding calendar year.
                If annuity  payments  commence  in  accordance  with  Article XV
                before the Required Beginning Date, the applicable calendar year
                is the year such payments  commence.  If  distribution is in the
                form of an immediate  annuity  purchased after the Participant's
                death with the Participant's  remaining interest, the applicable
                calendar year is the year of purchase.

                (iv)   Participant's   Benefit   means   the   balance   of  the
                Participant's  Individual  Account as of the last valuation date
                in the calendar  year  immediately  preceding  the  Distribution
                Calendar Year (valuation  calendar year) increased by the amount
                of any contributions or forfeitures  allocated to the Individual
                Account  as of dates in the  valuation  calendar  year after the
                valuation  date  and  decreased  by  distributions  made  in the
                valuation  calendar year after the valuation  date. For purposes
                of this  Section  15.4(j)(iv),  if any  portion  of the  minimum


                                       62
<PAGE>

                distribution for the first Distribution Calendar Year is made in
                the second Distribution  Calendar Year on or before the Required
                Beginning Date, the amount of the minimum  distribution  made in
                the second Distribution  Calendar Year shall be treated as if it
                had been made in the immediately preceding Distribution Calendar
                Year.

                (v) Distribution Calendar Year means a calendar year for which a
                minimum  distribution is required.  For distributions  beginning
                before the Participant's death, the first Distribution  Calendar
                Year is the calendar  year  immediately  preceding  the calendar
                year which contains the Participant's  Required  Beginning Date.
                For distributions  beginning after the Participant's  death, the
                first  Distribution  Calendar Year is the calendar year in which
                distributions  are  required to begin  pursuant to this  Section
                15.4.

        Sec. 15.5  Withdrawals.  Except as provided in subsections (a), (b), (c)
and (d) below,  no amounts may be  withdrawn  by a  Participant  from his 401(k)

        may  withdraw  prior to  January  1, 1998 all or any part of his  401(k)
        Account and the vested  portion of his Employer  Account for a financial
        hardship only if, under uniform rules and regulations, the Administrator
        determines  that  (i) the  purpose  of the  withdrawal  is to  meet  the
        Immediate  and  Heavy   Financial   Need  (as  defined   below)  of  the
        Participant,  (ii) the  withdrawal is necessary to satisfy the need, and
        (iii) the amount of the withdrawal does not exceed the lesser of (A) the
        aggregate value of the Participant's  401(k) Account and vested Employer
        Account as of the Valuation Date  immediately  preceding the date of the
        withdrawal,  (B) the  aggregate  of the actual  dollar  amount of Salary
        Reduction  Contributions  made on behalf of the Participant  pursuant to
        Section 3.1 and the value of the  Participant's  vested Employer Account
        as  of  the  Valuation  Date  immediately  preceding  the  date  of  the


                                       64
<PAGE>

        withdrawal or (C) the amount of such financial need  (including  amounts
        necessary to pay any  federal,  state or local income taxes or penalties
        reasonably  anticipated  to  result  from  the  distribution).  Hardship
        withdrawals  shall be taken from a Participant's  Individual  Account in
        the following order:  401(k) Account,  excluding earnings as provided in
        this paragraph above; and then Employer Account.

                For  purposes  of this  subsection  (d),  "Immediate  and  Heavy
        Financial  Need" shall mean (i) expenses  for medical care  described in
        Section 213(d) of the Code previously  incurred by the Participant,  his
        spouse or his dependents (as defined in Section 152 of the Code), or the
        amount  necessary for such persons to obtain  medical care  described in
        Section  213(d)  of the  Code,  (ii) the  purchase  (excluding  mortgage
        payments) of a principal residence of the Participant, (iii) the payment
        of  tuition,  related  educational  expenses,  fees and  room and  board
        expenses  for the next 12 months  of  post-secondary  education  for the
        Participant or his spouse, children or dependents (as defined in Section
        152 of the Code),  (iv) the need by the Participant to prevent  eviction
        from his  principal  residence  or  foreclosure  on the  mortgage of his
        principal residence and (v) such other  circumstances  determined by the
        Commissioner of Internal Revenue in revenue  rulings,  notices and other
        promulgated documents of general applicability.

                For  purposes  of this  subsection  (d), a  withdrawal  shall be
        considered  necessary  to satisfy a  Participant's  Immediate  and Heavy
        Financial Need if (i) the amount of the  withdrawal  does not exceed the
        amount  of  the   Participant's   Immediate  and  Heavy  Financial  Need
        (increased if requested by the  Participant by any amounts  necessary to
        pay any federal,  state or local  income  taxes or penalties  reasonably
        anticipated to result from the  withdrawal),  (ii) the  Participant  has
        obtained all distributions,  other than hardship  withdrawals under this
        subsection (d), and all nontaxable loans  (determined at the time of the
        loan)  currently  available  to the  Participant  under the Plan and all
        other   qualified   plans   maintained  by  the  Employer  in  which  he
        participates,  (iii) all  elective  deferrals  [as  defined  in  Section
        402(g)(3)  of the  Code] and  after-tax  employee  contributions  by the
        Participant  to the Plan and all other plans (as  described  in the next
        sentence)  maintained  by the Employer are  suspended for a period of 12
        months after receipt of the hardship withdrawal hereunder,  and (iv) the
        Participant's elective deferrals [as defined in Section 402(g)(3) of the
        Code] under the Plan and all other plans  maintained by the Employer for
        the taxable year immediately  following the taxable year of the hardship
        withdrawal may not exceed the applicable  dollar limit under Section 3.1
        for  such  following   taxable  year  reduced  by  the  amount  of  such
        Participant's  elective  deferrals  for the taxable year of the hardship


                                       65
<PAGE>

        withdrawal.  The suspension of elective deferrals and after-tax employee
        contributions  described  in clause (iii) in the  immediately  preceding
        sentence  also  must  apply  to all  other  qualified  plans  and to all
        nonqualified plans of deferred compensation  maintained by the Employer,
        other  than any  mandatory  employee  contribution  portion of a defined
        benefit plan,  including stock option,  stock purchase and other similar
        plans, but not including health or welfare benefit plans (other than the
        cash  or  deferred   arrangement  portion  of  a  cafeteria  plan).  The
        application of clauses (iii) and (iv) of this  paragraph  shall cease as
        of  December  31,  1997   notwithstanding   the  date  of  the  hardship
        withdrawal.

                Except as provided in clause (iii) of the immediately  preceding
        paragraph, a withdrawal pursuant to this subsection (d) shall not result
        in a suspension of participation in the Plan.

                No withdrawal may be made under this subsection (d) by reason of
        an event  described  in (3),  (4) or (5) of the first  paragraph of this
        subsection  (d)  unless the  distribution  is in the form of a "lump sum
        distribution"  within the  meaning of Section  401(k)(10)(B)(ii)  of the
        Code.  In  addition,  no  withdrawal  may be made by  reason of an event
        described in (3) or (4) of the first  paragraph of this  subsection  (d)
        unless the transferor  corporation  continues to maintain the Plan after
        the  disposition.  Each withdrawal under this subsection (d) at the time
        it is paid shall be charged to the Individual Account of the Participant
        from which the withdrawal is made.

All   withdrawals   under   this   Section   15.5  shall  be  made  as  soon  as
administratively practicable following the date Notice of withdrawal is received
by the Administrator. The advance Notice requirement of this Section 15.5 may be
waived by the  Administrator in its sole discretion.  All withdrawals under this
Section 15.5 shall be based on the value of the  Participant's  401(k)  Account,
Savings Account, Employer Account and Rollover Account, as the case might be, as
of the Valuation Date for which the withdrawal is to be made.  Withdrawals under
this Section 15.5 shall,  to the extent  required by the Code, be subject to the
provisions of Section 15.11. A Participant  may, subject to any restrictions and
limitations  imposed on a particular  Investment Fund, direct  withdrawals under
this Section 15.5 which are less than the full value of any  Individual  Account
from  which an  amount  is  withdrawn  to be  charged  to any one or more of the
Investment  Funds in which such Individual  Account is invested.  Such direction
shall be given by the Participant  with his Notice to withdraw and shall specify
the manner in which the withdrawal will be allocated among the Investment Funds.
If a  Participant  does not  specify the manner in which a  withdrawal  shall be


                                       66
<PAGE>

allocated  among  Investment  Funds,  the   Administrator   shall  allocate  the
withdrawal  on  a  pro  rata  basis  among  the  Participant's  Investment  Fund
elections, subject to any restrictions or limitations applicable to a particular
Investment Fund.  Payments under this Section 15.5 shall be made in a single sum
payment in cash.

        Sec.  15.6  Claims   Procedure.   The   Administrator   shall  make  all
determinations as to the right of any person to receive a benefit. The denial by
the  Administrator  of a claim for benefits  under the Plan shall be stated in a
written instrument signed by the Administrator and delivered to or mailed to the
claimant within 60 days after receipt of the claim by the Administrator,  unless
special  circumstances require an extension of time for processing the claim, in
which case a  determination  shall be made as soon as possible,  but in no event
later than 120 days after receipt of the claim.  Written notice of the extension
shall be  furnished  to the  claimant  prior to the  termination  of the initial
60-day period and shall indicate the  circumstances  requiring the extension and
the date by which the Administrator expects to render its decision.  The written
decision shall set forth:

        (a)     the specific reason or reasons for the denial;

        (b)     a specific reference to the pertinent provisions of the Plan on
        which the denial is based;

        (c) a description  of any additional  material or information  necessary
        for the  claimant  to  perfect  a claim and an  explanation  of why such
        material or information is necessary; and

        (d)     a statement that the claimant may:

                (i)   request a review upon written application to the
                Administrator;

                (ii)  review pertinent plan documents; and

                (iii) submit issues and comments in writing.

If notice of the denial is not furnished in accordance with the above procedure,
the claim shall be deemed denied and the claimant  shall be permitted to proceed
with the review procedure.  A request by the claimant for a review of the denied
claim must be delivered  to the  Administrator  within 60 days after  receipt by
such  claimant  of  written  notification  of the  denial  of  such  claim.  The
Administrator  shall,  not later than 60 days after  receipt of a request  for a
review,  make a  determination  concerning the claim.  If special  circumstances
require,  the Administrator  shall notify the claimant that an extension of time
for  processing,  not in excess of 120 days  after  receipt of the  request  for
review, is necessary.  A written  statement stating the decision on review,  the
specific  reasons for the decision,  and the specific  provisions of the Plan on


                                       67
<PAGE>

which the decision is based shall be mailed or delivered to the claimant  within
such 60 (or 120) day period.  If the decision on review is not furnished  within
the  appropriate  time,  the  claim  shall  be  deemed  denied  on  review.  All
communications  from the  Administrator  to the  claimant  shall be written in a
manner calculated to be understood by the claimant.

        Sec. 15.7 Administrator's Duty to Trustee. The Administrator will notify
the  Trustee  at the  appropriate  time  of all  facts  which  may be  necessary
hereunder  for the proper  allocation  of increases,  decreases,  expenses,  and
contributions for Participants,  the proper payment or distribution of benefits,
or the proper  performance  of any other act required of the Trustee  hereunder.
The  Administrator  will  notify the  Trustee of such facts as are needed by the
Trustee to perform its functions under the Plan. The  Administrator  will secure
appropriate  elections,  directions,  and designations for Participants,  Former
Participants and Beneficiaries provided for in the Plan.

        Sec. 15.8 Duty to Keep Administrator  Informed of Distributee's  Current
Address.  Each Participant and Beneficiary must file with the Administrator from
time to time in writing his post  office  address and each change of post office
address.  Any  communication,  statement or notice  addressed to a  Participant,
Former Participant or Beneficiary at his last post office address filed with the
Administrator or if no address is filed with the Administrator  then at his last
post office  address as shown on an Employer's  records,  will be binding on the
Participant or Former Participant,  and his Beneficiary, for all purposes of the
Plan.  Neither the Administrator nor the Trustee shall be required to search for
or locate a Participant, Former Participant or Beneficiary.

        Sec. 15.9 Failure to Claim Benefits.  If the Administrator  notifies the
Participant,  Former  Participant or Beneficiary by registered or certified mail
at his  last  known  address  that he is  entitled  to a  distribution  and also
notifies him of the provisions of this Section 15.9, and the Participant, Former
Participant  or  Beneficiary  fails to claim his benefits under the Plan or make
his current  address known to the  Administrator  within a reasonable  period of
time after such  notification,  the  Administrator  shall direct that all unpaid
amounts which would have been payable to such Participant, Former Participant or
Beneficiary  will be forfeited  and applied as provided in Section  14.5. In the
event that the  Participant,  Former  Participant or Beneficiary is subsequently
located,   the  amounts  which  were  forfeited  shall  be  distributed  to  the
Participant, Former Participant or Beneficiary, and an Employer shall contribute
an amount to the Plan which is equal to the amount  distributed  under the terms
of this Section 15.9 to the extent that such amount cannot be reinstated through
forfeitures occurring during the Year of payment.  Notwithstanding the preceding
sentences,  if the  Administrator  is  trying to  locate a  Participant,  Former
Participant  or  Beneficiary   in  connection   with  (i)  a  minimum   required
distribution  under Section 15.4 or (ii) a return of Excess  Elective  Deferrals


                                       68
<PAGE>

under Section 4.1, Excess Salary Reduction  Contributions  under Section 4.3, or
Excess  Matching   Contributions   under  Section  5.2,  and  the  Administrator
determines that such Participant,  Former  Participant or Beneficiary  cannot be
located, the Administrator shall establish an escrow account outside of the Plan
in the name of that  Participant,  Former  Participant or Beneficiary and direct
the Trustee to distribute such amount to that account.

        Sec. 15.10 Distribution Pursuant to Qualified Domestic Relations Orders.
The Administrator shall establish policies and procedures for reviewing domestic
relations  orders  relating  to  a  Participant's  interest  in  the  Plan.  The
Administrator  or  its  delegate  shall  determine  whether  any  such  domestic
relations order is a Qualified  Domestic  Relations Order.  Notwithstanding  any
other provision of the Plan to the contrary, effective September 1, 1997, if the
provisions of a Qualified  Domestic  Relations Order provide that  distributions
shall be made to an Alternate Payee prior to the time that the Participant  with
respect to whom the  Alternate  Payee's  benefits are derived  attains age 50 or
would be entitled to a distribution  of assets from the Plan, the  Administrator
shall direct the Trustee to commence  payments to the Alternate Payee as soon as
administratively  practicable  following  the later of (i) the  receipt  of such
Qualified  Domestic  Relations Order by the  Administrator  or (ii) the date the
Administrator   receives  the  Alternate   Payee's   written   consent  to  such
distribution.  Until such time as payment is made to an Alternate Payee pursuant
to this Section 15.10,  the Alternate  Payee shall have no rights under the Plan
other than the rights of a Beneficiary and the right to direct the investment of
amounts  awarded to the Alternate  Payee. If an Alternate Payee does not receive
an immediate  distribution  pursuant to this Section  15.10,  the  Administrator
shall direct the Recordkeeper to identify the Alternate  Payee's interest in the
Trust Fund pending a distribution to the Alternate Payee and the Alternate Payee
may direct the  investment of the Alternate  Payee's  interest in the Trust Fund
pursuant the provisions of Section 22.8.

        Sec. 15.11 Tax Withholding and  Participant's  Direct  Rollover.  Unless
provided otherwise in regulations  promulgated by Secretary of the Treasury,  to
the extent  required  under Section 3405 of the Code, the Trustee shall withhold
20% of the taxable  portion of the Plan  distribution  or  withdrawal  made to a
Participant,  Former  Participant or  Beneficiary  after December 31, 1992 which
constitutes  an  eligible  rollover  distribution  within the meaning of Section
402(c)(4)  of the Code.  Any amount  withheld  shall be deposited by the Trustee
with the Internal  Revenue  Service for the purpose of paying the  distributee's
federal income tax liability  associated  with the  distribution  or withdrawal.
Notwithstanding  the  foregoing  provisions,  commencing on and after January 1,
1993,  each  Participant,  each  Former  Participant  and each spouse (or former
spouse under a Qualified  Domestic  Relations  Order) of a Participant or Former
Participant shall be given the right to elect [pursuant to Section 401(a)(31) of


                                       69
<PAGE>

the Code] to rollover all or any portion of the taxable  amount of such person's
distribution  or withdrawal  (subject to limitations and  restrictions,  if any,
adopted by the Administrator in accordance with applicable Treasury regulations)
directly to an eligible  retirement  plan as defined in Section  402(c)(8)(B) of
the Code as limited by Section 402(c)(9) of the Code and, to the extent a direct
rollover is elected by any such person,  the  withholding  requirements  of this
Section 15.11 will not apply.  If permitted by the Code or  applicable  Treasury
regulations,  a direct  rollover as described in the  preceding  sentence may be
accomplished by delivering a check from the Plan to the  distributee  payable to
the trustee or custodian of the eligible  retirement  plan.  Each such  election
shall be in writing on a form prescribed by the  Administrator  for such purpose
and given to the Participant,  Former  Participant or spouse within a reasonable
period of time prior to the distribution or withdrawal.

                                   Article XVI

                                     NOTICES

     Sec.  16.1  Notice.  As soon as  practicable  after a  Participant,  Former
Participant or Beneficiary makes a request for payment,  the Administrator shall
notify the Recordkeeper of the following information and give such directions as
are necessary or advisable under the circumstances:

        (a)     name and address of the Participant, Former Participant or
        Beneficiary, and

        (b)     amount to be distributed.

In  addition  to  the  information   described  above,  for   distributions  and
withdrawals  occurring after December 31, 1992, the  Administrator  shall notify
the Recordkeeper and/or the Trustee, if applicable, as to the identity,  address
and other  pertinent  information of eligible  retirement  plans as described in
Section  402(c)(8)(B)  of the Code to which the payee has  elected  to  rollover
directly such distribution or withdrawal pursuant to Section 15.11 of the Plan.

        Sec.  16.2  Modification  of  Notice.  At any time and from time to time
after giving the Notice as provided for in Section 16.1, the  Administrator  may
modify  such  original  Notice  or any  subsequent  Notice by means of a further
Notice or notices to the  Trustee but any action  taken or payments  made by the
Trustee pursuant to a prior Notice shall not be affected by a subsequent Notice.

        Sec. 16.3 Reliance on Notice.  Upon receipt of any Notice as provided in
this Article XVI, the  Recordkeeper  and/or the Trustee,  as  applicable,  shall
promptly take whatever action and make whatever payments are called for therein,
it being intended that the Trustee may rely upon the  information and directions
in such Notice absolutely and without question. However, the Trustee may call to
the  attention of the  Administrator  any error or  oversight  which the Trustee
believes to exist in any Notice.

                                  Article XVII

                        AMENDMENT OR TERMINATION OF PLAN

      Sec. 17.1   Amendment or  Termination by Company.  At any time the Company
acting through its governing body may amend or modify the Plan, retroactively or
otherwise, or may terminate the Plan, subject,  however, to the other provisions
of this  Article  XVII.  Such  termination  may be made  without  consent  being
obtained from the Trustee, the Recordkeeper, any Employer or Affiliated Company,
the Administrator,  the Committee, the Participants or their Beneficiaries,  the
Employees  or any other  interested  person.  Also the Plan shall be  considered
terminated if the Company ceases  business  operations or if there is a complete
discontinuance of Employer contributions to the Plan.

     Sec. 17.2 Effect of Amendment.  No amendment or modification  hereof by the
Company,  unless  made to secure the  approval of the  Commissioner  of Internal
Revenue or other governmental bureau or agency, shall:

        (a) operate  retroactively  to reduce or divest the then vested interest
        in any  Individual  Account  or to  reduce or divest  any  benefit  then
        payable hereunder; or

        (b) change the duties or  responsibilities  of the  Trustee  without the
        written consent or approval of the Trustee.

Each such amendment  shall be in writing signed by duly  authorized  officers of
the Company with such consents or approval,  if any, as provided above and shall
become effective as designated in such amendment.

        Sec.   17.3   Distribution   on   Termination   or   Discontinuance   of
Contributions.  Upon  termination  of the  Plan or  complete  discontinuance  of
contributions to the Plan, any amount of the Trust Fund previously  unallocated,
including  any amounts in a suspense  account  established  under  Article VIII,
shall be allocated  (unless such allocation would violate Article VIII), and the
Individual Accounts of all Participants,  Former Participants, and Beneficiaries
shall thereupon be and become fully vested and nonforfeitable to the extent then
funded.  The Trustee  shall  deduct  from the Trust Fund all unpaid  charges and
expenses including those relating to said termination, except as the same may be
paid by an Employer. The Trustee shall then adjust the balance of all Individual
Accounts  on the basis of the net value of the Trust  Fund.  The  Trustee  shall
distribute the amount to the credit of each Participant,  Former Participant and
Beneficiary when all appropriate  administrative procedures have been completed.
If any  amount in a  suspense  account  shall not be  allocable  because  of the
provisions of Article VIII, such amount shall be returned to the Employer.  Upon
any complete  discontinuance of contributions by an Employer,  the assets of the
Trust Fund shall be held and  administered by the Trustee for the benefit of the
Participants employed by such Employer  discontinuing  contributions in the same


                                       71
<PAGE>

manner and with the same powers,  rights, duties and privileges herein described
until the Trust Fund with respect to such  Employer has been fully  distributed.
Upon the partial  termination of the Plan,  the Individual  Accounts of affected
Participants,  Former  Participants  and  Beneficiaries  shall  thereupon be and
become  fully vested and  nonforfeitable  to the extent then funded and shall be
distributed to such Participants,  Former  Participants and Beneficiaries by the
Trustee when all appropriate  administrative  procedures have been completed. If
no other defined  contribution plan [other than an employee stock ownership plan
as defined in Section  4975(e)(7) of the Code or a simplified  employee  pension
plan as defined in Section  408(k) of the Code] is  maintained by the Company or
any other  Affiliated  Company as of the Plan termination  date,  subject to the
requirements  of Section 15.11,  the  Administrator  shall direct the Trustee to
distribute each  Participant's  entire  Individual  Account in a single lump sum
distribution  without his consent as soon as administratively  practicable after
the later of (i) the termination date of the Plan or (ii) the receipt  following
application  of a  favorable  determination  letter  from the  Internal  Revenue
Service with respect to the termination of the Plan. If, however, the Company or
any Affiliated  Company maintains another defined  contribution plan [other than
an employee stock ownership plan as defined in Section 4975(e)(7) of the Code or
a simplified  employee pension plan as defined in Section 408(k) of the Code] as
of the Plan termination date, then except as provided in the next sentence, each
Participant's  entire  Individual  Account shall be  transferred by the Trustee,
without the Participant's  consent,  to such other defined  contribution plan. A
Participant  may request in writing that the Trustee  distribute  his Individual
Account,  excluding  the  balance  attributable  to his  401(k)  Account  unless
distribution of such accounts would be permitted  under Section  401(k)(2)(B) of
the Code and the applicable Treasury  regulations  thereunder,  in a single lump
sum  distribution,  subject to the  requirements  of Section  15.11,  as soon as
administratively  practicable after the later of (i) the termination date of the
Plan or (ii) the receipt  following  application  of a  favorable  determination
letter from the Internal  Revenue Service with respect to the termination of the
Plan.

        Sec. 17.4 Reversion of Contributions to Employer.  Except as provided in
Section 3.5 and Section 17.3,  under no  circumstances  or conditions  shall the
Trust  Fund or any  portion  thereof  revert to any  Employer  or be used for or
diverted to the benefit of anyone other than Participants,  Former  Participants
and  Beneficiaries,  it being  understood  that the Trust  Fund shall be for the
exclusive benefit of Participants, Former Participants and Beneficiaries.

        Sec. 17.5  Amendment of Vesting  Schedule.  At any time that the vesting
schedule of the Plan is amended, or the Plan is amended in any way that directly
or  indirectly  affects  the  computation  of the  Participant's  nonforfeitable


                                       72
<PAGE>

interest in his Individual Account,  each Participant who has completed a Period
of Service of at least three  years,  whether or not  consecutive,  may elect to
have his vested interest in his Employer  Account  determined  under the vesting
schedule in effect prior to such amendment. An election made under the preceding
sentence may be made at any time within 60 days after the later of the date:

        (a) the amendment is adopted;

        (b) the amendment becomes effective; or

        (c) the  Participant  is issued  written  notice of the amendment by the
        Administrator.

An election under this Section shall be made in a written  instrument  delivered
to the  Administrator  and once made, shall be irrevocable.  For the purposes of
this Section,  a Participant  shall be considered to have  completed a Period of
Service of at least  three  years,  described  in this  Section if he shall have

plan of deferred compensation maintained or to be established for the benefit of
all or some of the  Participants  in this  Plan,  the  assets of the Trust  Fund
applicable to such  Participants  shall be  transferred  to the other trust fund

        he would have been  entitled to receive  immediately  before the merger,
        consolidation, or transfer (if this Plan had then terminated); and

        (b) such other plan and trust fund are qualified under Section 401(a) of
        the Code and exempt from tax under Section 501(a) of the Code.

Named  Fiduciary  may,  by  written  instrument,  allocate  some  or  all of its
responsibilities  to another  fiduciary,  including  the  Trustee,  or designate
another person to carry out some or all of its fiduciary responsibilities.  Each
fiduciary to whom  responsibilities are allocated by the Named Fiduciary will be
furnished a copy of the Plan and their acceptance of such responsibility will be
made by  agreeing  in  writing  to act in the  capacity  designated.  The  Named
Fiduciary  shall not be liable  for an act or  omission  of any  person  (who is
allocated  a fiduciary  responsibility  or who is  designated  to carry out such
responsibility) in carrying out a fiduciary  responsibility except to the extent
that with respect to the allocation or  designation,  continuation  thereof,  or
implementation or establishment of the allocation or designation  procedures the
Named Fiduciary (i) did not perform all of his duties and  responsibilities  and
exercise his powers  hereunder  with the care,  skill,  prudence,  and diligence
under  the  circumstances  then  prevailing  that a prudent  man  acting in like
capacity  and  familiar  with  such  matters  would  use  in the  conduct  of an
enterprise of like character and with like aims, (ii) knowingly  participates in
or knowingly  undertakes  to conceal an act or omission of another  fiduciary of
the Plan,  with the knowledge that such act or omission is a breach of fiduciary
responsibility, (iii) did not make reasonable efforts under the circumstances to
remedy a breach of fiduciary  responsibility  of which the Named  Fiduciary  has
knowledge,  or  (iv)  did  not  carry  out  its  specific  responsibilities,  in
accordance  with the  standard set forth in (i) above,  and as a result,  it has
enabled another fiduciary of the Plan to commit a breach. Any person or group of
persons may serve in more than one fiduciary capacity with respect to the Plan.

     Sec.  19.8  Expenses  of  Administration.  Except to the extent  paid by an
Employer, the Administrator shall cause the Trustee to pay all expenses incurred

     Sec. 20.1 Transfer of  Employment to Another  Employer.  When an Employee's
employment with any Employer is terminated,  but such Employee continues to be a

participation, and Plan benefits.

Employer Account credited with his share of his former Employer's  contributions


                                       76
<PAGE>

and with his share of his new  Employer's  contributions.  The  aggregate of the
Salary Reduction  Contributions  by such  Participant  during the portion of the
Year employed by an Employer  shall  constitute  the basis for his allocation of
that particular Employer's Matching Contribution,  if any, for that Year and the
aggregate of the  Participant's  Annual  Compensation  during the portion of the
Year employed by an Employer  shall  constitute  the basis for his allocation of
that particular Employer's profit sharing  contribution,  if any, for that Year.

Company) to reduce the contribution of any or all Employers during the Year.

governed solely  by the  terms of the Trust  Agreement,  reference  to  which is

     Sec.  21.3     Benefits  Only from Trust Fund.  Any person having any claim
under  the  Plan  will  look  solely  to  the  assets  of  the  Trust  Fund  for
satisfaction.  In no event will any Employer or any of its officers,  Employees,
agents,  members of its board of directors,  the Trustee, any successor trustee,
the Administrator, the Recordkeeper or any member of the Committee, be liable in
their individual  capacities to any person  whomsoever,  under the provisions of
the  Plan or  Trust  Agreement,  absent a  breach  of  fiduciary  responsibility
determined pursuant to the applicable provisions of ERISA.

     Sec. 21.4    Trust Fund Applicable  Only to Payment of Benefits.  The Trust
Fund will be used and applied  only in  accordance  with the  provisions  of the
Plan,  to provide the  benefits  thereof,  except as  provided  in Section  19.8


                                       77
<PAGE>

regarding  payment  of  administrative  expenses,  and no part of the  corpus or
income of the Trust Fund will be used for, or diverted to,  purposes  other than
for the exclusive benefit of Participants and other persons thereunder  entitled
to benefits.

     Sec.  21.5 Texas Trust Code.  Although  it is intended  that the  foregoing
powers of the Trustee be  applicable  hereunder,  it is also  intended  that all
provisions of the Texas Trust Code, and any amendments thereto, not inconsistent
with the above  enumerated  powers  or other  provisions  of the Plan,  shall be
applicable in the administration of the Trust Fund.

     Sec. 21.6    Voting of Company Stock. The Trustee shall,  upon notice to it
of any stockholders'  meeting of the Company,  promptly cause the Transfer Agent
for the  Company  (the  "Transfer  Agent") to send each  Participant  and Former
Participant  a copy of the proxy  solicitation  materials,  together with a form
requesting  confidential  voting  instructions  to the Transfer Agent  regarding
shares of Company Stock allocated to his Individual  Account.  Each  Participant
and Former  Participant shall be entitled to direct the Trustee as to the manner
in which all shares (including  fractional shares) of Company Stock allocated to
his Individual Account are to be voted, provided he delivers instructions to the
Transfer Agent  directing it how to vote such shares at least five business days
prior to the date such vote shall be  required.  In the event a  Participant  or
Former Participant delivers conflicting instructions, the instructions delivered
last in time shall  control.  In the event a Participant  or Former  Participant
fails  to  deliver  such  instructions,  the  Trustee  shall  vote  such  shares
proportionately  to the  ratio  of the  votes  of the  Participants  and  Former
Participants who have delivered  voting  instructions to the Transfer Agent. All
instructions  shall  be  maintained  by the  Transfer  Agent  to  safeguard  the
confidentiality of the instructions.

        Sec.  21.7 Tender and Exchange  Offers.  The  provisions of this Section
21.7 shall apply in the event that a tender  offer,  which is subject to Section
14(d)(1) of the Securities  Exchange Act of 1934, as amended, is made for shares
of Company  Stock or an offer to  exchange  securities  of another  company  for
shares of Company Stock,  which is the subject to the Securities Act of 1933, as
amended,  is made. Upon such a tender or exchange offer  occurring,  the Company
and the Trustee shall utilize their best efforts to cause the Transfer  Agent to
notify  each  affected  Participant  and Former  Participant  and to cause to be
distributed to him such  information as will be distributed to the  stockholders
of the Company  generally in connection  with any such tender or exchange  offer
and a form by which  the  Participant  or  Former  Participant  may  direct  the
Transfer  Agent in writing as to what  action,  as set forth  below,  to take on
behalf of that  Participant or Former  Participant with respect to the shares of


                                       78
<PAGE>

Company  Stock  allocated  to his  Individual  Account  under the  Plan.  If the
Transfer  Agent does not receive such written  directions  from a Participant or
Former Participant, the Transfer Agent shall not tender or offer to exchange any
shares of the Company Stock held in that  Participant's or Former  Participant's
Individual Account.

        (a) Cash  Tender  Offer.  In  connection  with a cash  tender  offer,  a
        Participant  or Former  Participant  may  direct the  Transfer  Agent to
        tender any or all shares of Company Stock held in the  Participant's  or
        Former  Participant's  Individual  Account.  Any  cash  received  by the
        Trustee as a result of such  tender  shall be invested by the Trustee in
        such short-term  interest  bearing  investments as it deems  appropriate
        pending  direction from Participants and Former  Participants  regarding
        the  reinvestment  of such cash in the  Investment  Funds then available
        under the Plan.

        (b) Exchange  Offer. In connection with an exchange offer, a Participant
        or  Former  Participant  may  direct  the  Transfer  Agent to offer  for
        exchange any or all shares of Company Stock held in the Participant's or
        Former  Participant's  Individual Account.  Any property received by the
        Trustee in connection with such exchange shall be held by the Trustee in
        separate accounts for the affected  Participants and Former Participants
        pending directions from them regarding the reinvestment of such property
        in the Investment Funds that are available under the Plan.

        (c) Tender and Exchange Offer.  In connection with a combination  tender
        and exchange  offer, a Participant or Former  Participant may direct the
        Transfer  Agent to tender  and offer for  exchange  any or all shares of
        Company  Stock  held  in  the  Participant's  or  Former   Participant's
        Individual  Account with any cash received by the Trustee as a result of
        such tender treated as provided in subsection (a) above and any property
        received  by the  Trustee in  connection  with the  exchange  treated as
        provided in subsection (b) above.

        A tender or exchange  offer  direction  given by a Participant or Former
Participant  may  be  revoked  by  the  Participant  or  Former  Participant  by
completion of the form prescribed  therefor by the Administrator,  provided such
form is filed with the Transfer  Agent at least two  business  days prior to the
withdrawal-date-deadlines provided for in the regulations with respect to tender
or exchange offers prescribed by the Securities and Exchange Commission.

        The Transfer Agent shall use its best efforts to effect on a uniform and
nondiscriminatory  basis the sale or exchange of the shares of Company  Stock as
directed  by the  Participants  and Former  Participants.  However,  neither the
Transfer Agent,  the  Administrator,  the Committee nor the Trustee insures that
all or any part of the shares of the Company Stock  directed by a Participant or


                                       79
<PAGE>

Former Participant to be tendered or exchanged will be accepted under the tender
or exchange offer. Any such shares of Company Stock not so accepted shall remain
in  the  Participant's  or  Former  Participant's  Individual  Account  and  the
Participant  or Former  Participant  shall continue to have the same rights with
respect  to such  shares of  Company  Stock as he had  immediately  prior to the
Transfer Agent's tendering of the shares.

        If a tender or exchange  offer is made,  the  Administrator  shall adopt
such  rules,  prescribe  the  use  of  such  special  administrative  forms  and
procedures,   delegate  such  authority,  take  such  action  and  execute  such
instruments  or documents  and do every other act or thing as shall be necessary
or in its  judgment  proper for the  implementation  of this Section  21.7.  All
instructions from  Participants  and Former  Participants  regarding a tender or
exchange  offer shall be  maintained  by the  Transfer  Agent to  safeguard  the
confidentiality of the instructions.

        Notwithstanding  anything in the Plan to the contrary,  in administering
the tendering or exchange of shares pursuant to the applicable provisions of the
Plan, it is intended that the  confidentiality  of the tenders or exchanges,  as
the case may be, made by  Participants  or Former  Participants  pursuant to the
provisions of the Plan shall be maintained by the Transfer Agent as contemplated
in Section 203 of the General Corporation Law of the State of Delaware.

                                  Article XXII

                            INVESTMENTS AND CONTRACTS

     Sec.  22.1  Permitted  Investments.  The  investments  permitted  under the
provisions  of  this  Article  XXII  shall  be in  addition  to any  investments
authorized pursuant to the provisions of the Trust Agreement.

        Sec. 22.2  Investment of Trust  Assets.  In addition to all  investments
allowable  under the Texas Trust Code,  and  subject to the  instructions  of an
Investment  Advisor  who is duly  appointed  as provided  in Section  22.5,  the
Trustee may invest and reinvest the  principal  and income of the Trust Fund and
shall keep such assets  invested,  without  distinction  between  principal  and
income, in such property, real or personal, or part interests therein,  wherever
situated, as the Trustee may deem suitable without regard to the proportion such
property or property of a similar  character  held in the Trust Fund may bear to
the entire amount so held,  including,  but not limited to, capital,  common and
preferred stocks; personal,  corporate, and governmental obligations;  trust and
participation  certificates,   oil,  mineral,  or  gas  properties,  fee  simple
interests in real property;  royalty  interests or rights  (including  equipment
pertaining  thereto);  machinery,  equipment,  leaseholds;  mortgages (including
mortgages  inferior  to  other  liens);  other  interests  in real  or  personal


                                       80
<PAGE>

property;  notes and other evidences of  indebtedness  or ownership,  secured or
unsecured; partnership interests; contracts, and chooses in action. In addition,
the Trustee  shall,  upon  direction  of the Named  Fiduciary,  make a loan to a
Participant  to the extent  permitted in Section  22.11.  Also,  the Trustee may
purchase life  insurance or annuity  contracts as  hereinafter  provided in this
Article.  The  Trustee  shall be obliged to use good faith and to  exercise  its
honest  judgment  as to what  investments  are  from  time  to time in the  best
interests  of the  Trust  Fund and those  entitled  to  benefit  under the Plan.
Furthermore,  the  Trustee  may hold any  portion  of the Trust Fund in cash and
uninvested whenever it deems such holding necessary or advisable.

     Sec. 22.3    Investment in Qualifying Employer Real Property and Qualifying
Employer  Securities.  If  directed  by the  Named  Fiduciary,  the  Trustee  is
permitted  to hold or to  lease  or to  purchase  from or to sell or lease to an
Employer or any other person or entity "qualifying  employer real property," and
to hold,  or to  purchase  from or sell to an  Employer  or any other  person or
entity  "qualifying  employer  securities,"  as each term is  defined in Section
407(d) of ERISA.  Up to 100% of the fair market value of the assets of the Trust
Fund may be  invested  in  qualifying  employer  real  property  and  qualifying
employer  securities.  The Trustee shall  purchase and sell  securities  only in
compliance with applicable  state and federal  securities laws and in accordance
with directions of the Named Fiduciary.

     Sec. 22.4 Investment in Certificate of Deposit. The Trustee, if a bank, may
invest  in  certificates  of  deposit  issued  by  the  Trustee   provided  such
certificates of deposit bear both a competitive and reasonable rate of interest.

     Sec. 22.5     Appointment of Investment  Advisor.  The Named  Fiduciary may
appoint an  investment  advisor as  permitted  by Section  402(c)(3) of ERISA to
direct the Trustee  with regard to the  investment  of the assets held under the
Plan.  For  purposes of this Section  22.5,  "investment  advisor"  shall mean a
fiduciary of the Plan who (i) is registered  as an investment  advisor under the
Investment  Advisors Act of 1940,  (ii) is a bank, as defined in the  Investment
Advisors Act of 1940, or (iii) an insurance  company qualified under the laws of
more than one state to manage,  acquire, or dispose of any asset of the Plan. If
such an investment advisor be so appointed,  the Trustee shall invest the assets
held under the Plan in accordance with the written directions received from such
investment advisor.  The Trustee shall not be obligated to accept direction from
the investment  advisor until such  investment  advisor  acknowledges in writing
that it is a fiduciary of the Plan.

        Sec. 22.6 Named Fiduciary's Control of Investments.  Notwithstanding any
other  provision in this Article XXII,  the Named  Fiduciary is hereby given the
right and power to direct the Trustee in writing to purchase,  sell,  lease,  or
otherwise  act for the  Trust  Fund in  regard to any  property,  whether  real,
personal,  tangible or intangible, and to the extent that the Named Fiduciary so
directs the Trustee,  all rights,  duties,  and obligations with respect to said


                                       81
<PAGE>

investment  shall have been allocated to the Named Fiduciary  within the meaning
of Section 405 of ERISA,  unless the  direction  is  contrary to ERISA,  and the
Trustee shall carry out said  directions  without being liable or responsible in
any way for any losses or unfavorable results resulting therefrom.  However, the
Named Fiduciary may specifically abdicate part or all of such right and power in
a written instrument so stating delivered to the Trustee. Furthermore, it is not
intended that the Trustee be required to ascertain  whether the Named  Fiduciary
desires to give written  directions  pursuant to this Section before the Trustee
exercises any power, right, or discretion granted to the Trustee hereunder.

        Sec. 22.7  Investment in Collective  Investment  Trust.  The Trustee may
invest the assets of the Trust Fund in any common or collective investment trust
or pooled investment fund maintained by a bank or trust company  supervised by a
state or federal  agency or pooled  investment  fund  maintained by an Insurance
Company licensed to do business in a state, including any bank, trust company or
Insurance Company which may be a fiduciary or an affiliate of a fiduciary of the
Plan,  which fund or funds then  provide  for the pooling of the assets of plans
described in Section 401(a) of the Code and exempt from tax under Section 501(a)
of the Code. The provisions of the document  governing such common or collective
investment  trust or pooled  investment  fund, as it may be amended from time to
time,  shall  govern any  investment  therein  and are hereby made a part of the
Plan.

        Furthermore,  the  Trustee,  for  collective  investment  purposes,  may
combine  into one trust  fund the Trust  and the trust  created  under any other
qualified  retirement plan of an Affiliated Company.  However, the Trustee shall
maintain  separate  records of account  for the assets of each trust in order to
properly reflect each Participant's interest under each such plan.

        Sec. 22.8 Participant Direction of Investments.  To the extent permitted
by the Administrator  from time to time, based on a  non-discriminatory  policy,
each  Participant and Former  Participant may direct the Trustee  concerning the
investment of his Individual  Account among  Investment  Funds made available to
the Participants and Former Participants by the Administrator from time to time.
Except with respect to the Employer's Matching  Contributions,  a Participant or
Former  Participant may elect to invest the balance of his Individual Account in
any one or more of the Investment Funds, but any such election of the Investment
Funds must be in 10% increments  totaling 100%. The Matching  Contributions  and
the portion of a Participant's  or Former  Participant's  Reinstatement  Account
attributable to Matching Contributions, if any, shall be invested solely in Fund
5. At the time an Employee  becomes a  Participant,  he shall  complete and file
with the Administrator using the form furnished by the Administrator designating


                                       82
<PAGE>

the Investment  Funds under which his Salary Reduction  Contributions,  accounts
under a plan merged into the Plan, Rollover Contributions,  if any, and Employer
profit sharing contributions allocated to his Individual Account, if any, are to
be  initially  invested.  Separate  elections  may not be made with  respect  to
different types of contributions.  The Employer's  profit sharing  contributions
pursuant to Section  3.3,  if any,  shall be  invested  in  accordance  with the
Participant's  election in effect at the time that such  Employer  contributions
are actually made to the Plan. The directions,  and any change thereto,  must be
in writing,  or, if permitted by the  Administrator,  by  Interactive  Telephone
Communication. If a Participant fails to direct the investment of his Individual
Account,  the entire balance of his Individual Account shall be invested in Fund
4.

     Sec.  22.9  Changes  to  Prior  Participant  Direction  of  Investments.  A
Participant's direction of the investment of his Individual Account shall remain
the same until changed by such  Partici-pant  pursuant to this  Section.  Except
with respect to the balance of his Individual  Account  attributable to Matching
Contributions,  a Participant  may change the direction of the investment of the
current balance of his Individual Account or future  contributions  allocated to
his Individual Account, or both, other than Matching Contributions, effective as
of any day following any Valuation  Date by filing the  appropriate  form, or by
Interactive  Telephone  Communication  (if applicable),  prior to such Valuation
Date.  Only one  investment  change  (whether  for  future  contributions,  past
contributions or both) may be made with respect to his Individual Account during
any calendar quarter.

     Sec.  22.10  Effect  of  Participant  Direction  of  Investments.   If  the
Participant  shall  exercise  any such  right to direct  the  investment  of his
Individual  Account,  then, to that extent,  the  obligations,  discretion,  and
duties with respect to such  investments  shall be deemed to have been allocated
to the Participant within the meaning of Section 404(c) of ERISA, and unless the
direction is contrary to ERISA or the  Administrator  shall  determine that such
investment would be  administratively  infeasible and so notify the Participant,
such  directions  shall be followed  and no  fiduciary  with respect to the Plan
shall be liable or responsible in any way for any losses or unfavorable  results
resulting  therefrom.  It is not intended that the  Administrator be required to
ascertain  whether  the  Participant  desires  to give  written  or  Interactive
Telephone  Communication  directions pursuant to this Section before the Trustee
exercises any power,  right,  or discretion  granted the Trustee under the Trust
Agreement.

     Sec. 22.11 Participant Loans. The Administrator may, in its sole discretion
and in accordance with a uniform and nondiscriminatory policy established by it,
permit loans to be made to a  Participant,  former  Participant  or  Beneficiary
provided  that  any  such  loan  (i)  shall  be  made   available  to  all  such
Participants,  former Participants and Beneficiaries on a reasonably  equivalent
basis,  (ii) shall not be made available to Highly  Compensated  Employees in an
amount greater than the amount made available to other Participants, (iii) shall


                                       83
<PAGE>

bear a reasonable rate of interest,  (iv) shall be adequately  secured,  and (v)
shall  provide for  periodic  repayment  over a  reasonable  period of time.  In
addition,  loans  granted or renewed  pursuant  to this  Section  22.11 shall be
granted or renewed in accordance  with a written loan policy  established by the
Administrator  (which policy,  when properly adopted,  is hereby incorporated by
reference  and  made a part  of this  Plan).  Such  written  loan  policy,  once
established  may be modified or amended in writing from time to time without the
necessity of amending this Section  22.11.  The loan policy  established  by the
Administrator  shall  comply  with  the  applicable   provisions  of  ERISA  and
regulations promulgated pursuant thereto and with any limitations imposed by the
Code and regulations promulgated pursuant thereto to prevent the loan from being
deemed to be a taxable distribution to the Participant.

                                  Article XXIII

                              TOP HEAVY PROVISIONS

        Sec.  23.1 Minimum  Allocation  Requirements.  For any Year in which the
Plan  is  a  Top  Heavy  Plan,   Employer   contributions   (excluding  Employer
contributions to Social and Salary Reduction  Contributions made to the Plan for
any  Year  under  Section  7.2  and  Matching   Contributions  included  in  the
Contribution  Percentage  test for the Year under  Section 5.1) and  forfeitures
which  are  allocated  to  any  Employee  who  has  satisfied  the   eligibility
requirements  of  Section  2.1,  without  regard to  whether  he has  elected to
participate  in the Plan pursuant to Section 2.2, and who on the last day of the
Year is a  Non-Key  Employee  shall  not be less  than the  lesser  of (i) three
percent of such Participant's Annual Compensation [as defined in Section 8.2(f)]
or (ii) the largest  percentage  of  Employer  contributions  (including  Salary
Reduction  Contributions  and Matching  Contributions),  as a percentage  of the
amount of the Annual Compensation [as defined in Section 8.2(f)] of Participants
who are Key  Employees,  but not in excess  of the  Compensation  Limitation  as
defined in Section 1.5 allocated to any such  Participant  who is a Key Employee
for that Year;  provided,  however,  if an Employer  maintains a defined benefit
plan which  designates this Plan to satisfy Section 401 or 410 of the Code, (ii)
above shall not apply. No Employer contributions allocated to a Non-key Employee
under this Section may be forfeited as a result of such Employee's withdrawal of
his Salary Reduction Contributions under Section 15.5(d).

        Sec. 23.2  Adjustment to Limitation on Allocations.  Notwithstanding the
provisions of Sections 8.2(h)(ii)(A) and 8.2(i)(ii)(A), beginning with the first
Year  beginning  after  December 31, 1983 in which the Plan is a Top Heavy Plan,
the following provisions shall be applicable to Section 8.2 of the Plan:



                                       84
<PAGE>

        (a) Section  8.2(h)(ii)(A)  shall be revised by  substituting  "1.0" for
        "1.25"  and  the   numerator  of  the  fraction   described  in  Section
        8.2(h)(iv)(A)  shall be revised by substituting  "$41,500" for "$51,875"
        unless  (i) the Plan would not be a Top Heavy Plan as defined in Section
        23.3(f) if "90%" were substituted for 60% in such  definition,  and (ii)
        the minimum  allocation  requirements  of Section 23.1 for a Participant
        who  is  a  Non-Key   Employee  are  satisfied  and,  in  applying  such
        provisions, "four percent" is substituted for "three percent;" and

        (b) Section  8.2(i)(ii)(A)  shall be revised by  substituting  "1.0" for
        "1.25"  unless  (i) the Plan would not be a Top Heavy Plan as defined in
        Section 23.3(f) if "90%" were  substituted  for 60% in such  definition,
        and (ii) the minimum benefit requirements of Section 416(h)(2)(A) of the
        Code are satisfied for all  participants  in the defined benefit pension
        plan who are Non-Key Employees.

        Sec. 23.3  Definitions.

        (a) "Determination  Date" means for any Year the Anniversary Date of the
        preceding  Year,  or in the  case of the  first  Year of the  Plan,  the
        Anniversary Date of that Year.

        (b) "Key Employee"  means, as of any  Determination  Date [as defined in
        Section  23.3(a)],  any Employee or former  Employee (or  Beneficiary of
        such  Employee)  who,  at any time  during the Year which  includes  the
        Determination Date, or during the preceding four Years, is:

                (i)  an  officer  of any  Employer  having  Annual  Compensation
                greater  than  50%  of  the  amount  in  effect  under   Section
                415(b)(1)(A) of the Code for any such Year;

                (ii) one of the ten Employees  having Annual  Compensation  from
                any Employer of more than the dollar  limitation in effect under
                Section   415(c)(1)(A)  of  the  Code  and  owning  the  largest
                interests in such Employer;

                (iii) a more than five percent owner of any Employer; or

                (iv) a more than one percent owner of any Employer having Annual
                Compensation from all Employers of more than $150,000.

        For purposes of this  subsection  (b),  Annual  Compensation  shall mean
        annual  compensation  as defined in Section  415(c)(3) of the Code,  but
        including  amounts  contributed  by the  Employer  pursuant  to a salary
        reduction  agreement which are excludable from the  Participant's  gross
        income under  Sections  125,  402(e)(3),  402(h)(1)(B)  or 403(b) of the
        Code. For purposes of subsection  (b)(i), no more than 50 Employees (or,
        if lesser,  the greater of three or ten percent of the Employees)  shall
        be treated as officers. For purposes of subsection (b)(ii) above, if two


                                       85
<PAGE>

        Employees have the same interest in an Employer, the Employee having the
        greater  Annual  Compensation  shall be  treated  as having  the  larger
        interest.  The  constructive  ownership rules of Section 318 of the Code
        (or the  principles  of that section,  in the case of an  unincorporated
        Employer) will apply to determine ownership in each Employer.

        (c) "Non-Key Employee" means any Employee who is not a Key Employee.

        (d) "Permissive  Aggregation Group" means the Required Aggregation Group
        plus any other  qualified plans  maintained by an Employer  which,  when
        considered  as a  group  with  the  Required  Aggregation  Group,  would
        continue to satisfy the  requirements  of Sections  401(a)(4) and 410 of
        the Code.

        (e) "Required  Aggregation  Group" means (i) each  qualified  plan of an
        Employer in which at least one Key Employee  participates,  and (ii) any
        other  qualified  plan of an Employer  which enables a plan described in
        (i) to meet the requirements of Sections 401(a)(4) or 410 of the Code.

        (f) "Top Heavy Plan" means the Plan for a Year beginning  after December
        31, 1983, if the Plan is the only plan maintained by an Employer and the
        top heavy ratio as of the Determination  Date exceeds 60%. The top heavy
        ratio is a fraction,  the  numerator  of which is the sum of the present
        value  of  the  Individual  Accounts  of  all  Key  Employees  as of the
        Determination  Date, the contributions due as of the Determination Date,
        and distributions made within the five-year period immediately preceding
        the Determination Date (including  distributions under a terminated plan
        which if it had not been  terminated  would  have  been  required  to be
        included in an  aggregation  group),  and the  denominator of which is a
        similar sum determined  for all Employees.  The top heavy ratio shall be
        calculated without regard to (i) the Individual Account of a Participant
        who is not a Key  Employee  but who was a Key  Employee in a prior Year,
        (ii) the Individual  Account of any individual who has not performed any
        services for an Employer at any time during the five-year  period ending
        on the  Determination  Date,  and (iii)  voluntary  deductible  Employee
        contributions,  if any.  The top heavy ratio,  including  distributions,
        rollover  and  transfers,  to the  extent  such items must be taken into
        account,  shall be calculated in accordance with Section 416 of the Code
        and the regulations thereunder. If an Employer maintains other qualified
        plans  (including  a  simplified  employee  pension  plan)  or has  ever
        maintained one or more defined benefit plans which have covered or could
        cover a  Participant  in this  Plan,  this  Plan is top heavy for a Year
        beginning  after  December  31, 1983 only if it is part of the  Required
        Aggregation  Group,  and the top  heavy  ratio  for  both  the  Required
        Aggregation Group and the Permissive  Aggregation Group exceeds 60%. The
        top heavy ratio shall be  calculated  as  described  above,  taking into
        account all plans  within the  aggregation  group and with  reference to


                                       86
<PAGE>

        Determination  Dates that fall within the same calendar  year;  provided
        that if a defined benefit plan is included in the aggregation group, the
        present  value of accrued  benefits  (instead  of account  balances)  of
        participants  in that plan shall be computed for purposes of calculating
        the top heavy ratio. The accrued benefit under a defined benefit plan in
        both the  numerator  and the  denominator  of the top  heavy  ratio  are
        increased  for  any  distribution  of an  accrued  benefit  made  in the
        five-year period ending on the  Determination  Date. The accrued benefit
        of a Participant other than a Key Employee shall be determined under (i)
        the method,  if any, that uniformly  applies for accrual  purposes under
        all defined benefit plans  maintained by the Employer,  or (ii) if there
        is no such method,  as if such benefit accrued not more rapidly than the
        slowest  accrual rate  permitted  under the  fractional  rule of Section
        411(b)(1)(C) of the Code. The value of account  balances and the present
        value of  accrued  benefits  will be  determined  as of the most  recent
        Allocation  Date that  falls  within or ends  with the  12-month  period
        ending on the  Determination  Date, except as provided in Section 416 of
        the Code and the  Treasury  regulations  thereunder  for the  first  and
        second plan years of a defined  benefit plan. The actuarial  assumptions
        (interest rate and mortality only) used by the actuary under the defined
        benefit  plan shall be used to  calculate  the present  value of accrued
        benefits from the defined benefit plan.

        IN WITNESS  WHEREOF,  ENSCO  International  Incorporated,  the  Company,
acting by and through its duly authorized officers, has caused this Agreement to
be executed as of the day and year first above written.

                                   LOAN POLICY
                                     FOR THE
                               ENSCO SAVINGS PLAN
                                     AND THE
                              DUAL DRILLING COMPANY
              EMPLOYEES TAX DEFERRED/THRIFT SAVINGS PLAN AND TRUST

ENSCO  International  Incorporated  ("ENSCO") and DUAL Holding Company  ("DUAL")
hereby establish,  effective January 1, 1998, the following loan policy pursuant
to the  provisions of Section 22.11 of the ENSCO Savings Plan and Section 8.4(j)
of the Dual  Drilling  Company  Employees Tax  Deferred/Thrift  Savings Plan and
Trust (the "DUAL Savings Plan") (collectively the "Plans").  This loan policy is
intended to form part of the Plans and satisfy the  procedures  of Department of
Labor ("DOL")  Regulation section  2550.408b-1(d),  as clarified by DOL Advisory
Opinion 89-30A. A "Participant,"  as defined below, may receive a loan under the
Plans only as permitted by this loan policy. Pursuant to DOL regulations, a copy
of this loan policy will be provided to each "Participant."

Administration  of Loan Program.  ENSCO and DUAL have appointed Brian Gifford to
administer  participant  loans under the Plans (the "Loan  Administrator").  The
Loan Administrator may, from time to time, delegate certain ministerial or other
nondiscretionary  duties  regarding  the  administration  of the loan program to
additional persons.

Loan Application and Terms. A "Participant"  may apply for a loan from the Plans
by completing a loan  application  and submitting it to the Loan  Administrator.
Subject to the limitations  set forth below, a  "Participant"  may only have one
(1) loan  outstanding  under the ENSCO Savings Plan and/or the DUAL Savings Plan
at any time  during a calendar  year.  In  addition,  a  "Participant"  may only
receive one (1) loan under the ENSCO  Savings  Plan and/or the DUAL Savings Plan
during  the  calendar  year.  For  purposes  of  this  loan  policy,   the  term
"Participant" means an active  participant,  a former participant or beneficiary
who is a "party  in  interest"  [within  the  meaning  of  section  3(14) of the
Employee Retirement Income Security Act of 1974, as amended ("ERISA")] or who is
otherwise  mandatorily eligible for plan loans under ERISA, the Internal Revenue
Code of 1986,  as amended (the "Code") or  regulations  and rulings  promulgated
thereunder.

All loans under the ENSCO  Savings  Plan and/or the DUAL  Savings  Plan shall be
granted from the  Participant's  vested  accounts under the applicable plan on a
pro-rata  basis in proportion to the size of the account in accordance  with the
applicable plan's most recently completed valuation.  The funds from each vested
account shall be withdrawn on a pro-rata basis from each of the investment funds
in which the account is invested  other than the ENSCO Company  Stock Fund.  All
loans must be amortized in level  payments at least  quarterly  over the term of
the loan.  Loan  payments  will be made  through  payroll  deduction  unless the
Participant is on an unpaid leave of absence or his  employment has  terminated,
in which case loan payments shall be made by check during such leave of absence.
Each loan, by its terms,  must be repaid within five (5) years except that loans
for the purchase of a primary  residence  may have a term not to exceed ten (10)
years.





                                       1
<PAGE>




Loan  Approval.  The Loan  Administrator  will  approve  loans on a uniform  and
nondiscriminatory basis without regard to a Participant's race, color, religion,
age,  sex  or  national  origin,  and  Plan  loans  shall  be  available  to all
Participants on a reasonably equivalent basis.

Limitation on Loan Amount. No loan shall be granted by the Loan Administrator in
an amount  (when  added to the  outstanding  balance  of all other  loans to the
Participant  under  the  Plans  or any  other  plan  maintained  by ENSCO or its
affiliates  [within the meaning of sections 414(b),  (c) or (m) of the Code]) in
excess of the lesser of:

         (a)      $50,000 minus the excess, if any, of the Participant's highest
                  plan loan balance within the immediately preceding twelve (12)
                  months,  over the outstanding  balance of loans from the Plans
                  to the Participant on the date the loan is made, or

          (b) fifty percent (50%) of the Participant's vested accounts under the
applicable plan.

Each loan under the ENSCO  Savings  Plan and/or the DUAL  Savings  Plan shall be
made from the  Participant's  applicable  plan  accounts  and the income or loss
associated with the loan shall be allocated to the Participant's  accounts.  The
minimum amount of any loan shall be $1,000.

Interest  Rate. All loans shall be granted at a fixed interest rate equal to the
prime rate of interest  published  in the Wall Street  Journal  plus one percent
(1%)  on  the  first  working  day  of  each  month,  unless  such  rate  is not
"reasonable"  within  the  meaning  of the  DOL  Regulations,  in  which  case a
reasonable  rate of  interest  shall be used.  Further,  in the  event  that the
interest  rate charged by the Plans is limited by state usury law at a time when
rates  charged on similar loans by  commercial  lenders are not so limited,  the
Loan  Administrator  will suspend  granting  loans under the program  until this
situation changes.

Security for Loan.  All loans  granted  under the ENSCO  Savings Plan and/or the
DUAL Savings Plan shall be secured with an irrevocable  pledge and assignment of
fifty percent (50%) of the  Participant's  vested  accounts under the applicable
plan, determined as of the date the loan is made. Such security shall be derived
from the remainder of the Participant's vested accounts used to fund the loan on
a  pro-rata  basis  in  proportion  to  the  size  of  the  account.   The  Loan
Administrator shall take all actions it deems necessary, including requiring the
Participant to execute additional  documents to perfect the ENSCO Savings Plan's
and/or the DUAL Savings Plan's  security  interest in the  Participant's  vested
accounts.

Default.  The Loan  Administrator  will treat this loan in default upon the
occurrence of any of the following:

         (a) any  scheduled  loan payment  remains  unpaid more than ninety (90)
days following the due date;










                                       2
<PAGE>






         (b) the making or furnishing of any  representation or statement to the
ENSCO  Savings Plan or the DUAL Savings Plan by or on behalf of the  Participant
which proves to have been false in any material respect when made or furnished;

         (c) the  making  of any  levy,  seizure  or  attachment  (other  than a
qualified  domestic  relations  order)  on the  Participant's  accounts  used as
collateral for the loan; or

         (d)  the  commencement  of  any  proceeding  under  any  bankruptcy  or
insolvency laws of, by or against the Participant.

The  Participant  will have the  opportunity to take the following  actions,  as
appropriate,  (i) repay  the loan,  (ii)  resume  current  status of the loan by
paying any missed payment plus interest,  or (iii) if  distribution is available
under the ENSCO  Savings  Plan or DUAL  Savings  Plan,  as  applicable,  request
distribution of the note. If the loan remains in default, the Loan Administrator
will offset the  Participant's  vested accounts by the amount of the outstanding
loan to the extent a distribution  to the  Participant is permissible  under the
ENSCO Savings Plan or DUAL Savings Plan, as applicable.  The Loan  Administrator
will treat the note as repaid to the extent of any permissible  offset.  Pending
final disposition of the loan, the Participant  remains obligated for any unpaid
principal and accrued interest.

Upon default of the loan,  the  Participant  shall be deemed to have  received a
taxable distribution equal to the outstanding balance of the loan at the time of
default in  accordance  with  section  72(p) of the Code.  In  addition,  if the
Participant  fails to make interest  payments on the loan following such default
and offset of the loan is not  permissible,  the Participant  will be treated as
having received a taxable  distribution  each year the loan remains  outstanding
equal to the amount of accrued  interest for such year.  Finally,  to the extent
that the  ENSCO  Savings  Plan or DUAL  Savings  Plan,  as  applicable,  may not
foreclose  immediately  on security  held by the Plan in the event of a default,
the Loan  Administrator  and  Trustee  shall  take  whatever  actions  they deem
necessary  and  appropriate  to protect the security  pending a  foreclosure  to
prevent a loss of  principal  or interest  from  occurring  with  respect to the
Plan's interest in the loan.

Acceleration  of Loans  Upon  Termination  of  Employment.  All  loans  shall be
accelerated and immediately due and payable upon a Participant's  termination of
employment with the Employer  [unless such  Participant is a "party in interest"
as defined in section  3(14) of ERISA or is otherwise  mandatorily  eligible for
Plan  loans  under  ERISA,  the  Code or  regulations  and  rulings  promulgated
thereunder]. If a Participant does not repay the loan within thirty (30) days of
his termination of employment,  the Loan Administrator  shall direct the Trustee
to offset the vested portion of the  Participant's  accounts by the  outstanding
amount of the loan.

Compliance  With  Internal  Revenue  Code.  No loans shall be granted,  renewed,
renegotiated or extended which at the time of such grant, renewal, renegotiation

                     SUPPLEMENTAL EXECUTIVE RETIREMENT PLAN

     THIS AGREEMENT, executed this 25th day of November, 1997, and effective the
first  day of  January,  1997  unless  specifically  provided  elsewhere  in the
Agreement, by ENSCO International  Incorporated,  having its principal office in
Dallas, Texas (hereinafter referred to as the "Company").

                              W I T N E S S E T H:

     WHEREAS,  effective April 1, 1995, Energy Service Company, Inc. adopted the
Energy Service Company, Inc. Select Executive Retirement Plan (the "Plan");

     WHEREAS,  the  name of the  company  was  changed  to  ENSCO  International
Incorporated;

     WHEREAS,  on November 11, 1997, the Company amended the Plan retroactive to
January 1, 1997 to provide a discretionary  profit sharing  contribution  and to
rename the Plan the ENSCO Supplemental Executive Retirement Plan;

     WHEREAS,  the  Company  desires  to amend and  restate  the Plan  effective
January 1, 1998 to clarify that eligible  employees must  contribute the maximum
amount  permitted by the Internal  Revenue Code to the ENSCO Savings Plan before
they may participate in basic and automatic deferral features of the Plan and to
modify the  operation  of the Plan so it will act as a  wrap-around  plan to the
ENSCO Savings Plan;

     NOW THEREFORE, the Plan is hereby amended and restated to read as follows:

                                    ARTICLE I

                                     PURPOSE

     The objective  and purpose of this Plan is to attract and retain  competent
officers and key executives by offering flexible  compensation  opportunities to
officers and key  executives of the Company and to offer them an  opportunity to
build an estate or supplement  income for use after  retirement.  In addition to
this Plan,  the Company  sponsors  certain  broad-based  employee  benefit plans
covering its employees.

     Through  this  Plan,  the  Company   intends  to  permit  the  deferral  of
compensation and to provide additional  benefits to a select group of management
or highly compensated employees of the Company. Accordingly, it is intended that
this Plan shall not constitute a "qualified  plan" subject to the limitations of
section  401(a) of the Internal  Revenue Code of 1986,  as amended (the "Code"),
nor shall it constitute a "funded plan", for purposes of such requirements.   It


                                       1
<PAGE>

is also  intended  that this Plan  shall be exempt  from the  participation  and
vesting  requirements  of Part 2 of Title I of the  Employee  Retirement  Income
Security Act of 1974, as amended ("ERISA"),  the funding  requirements of Part 3
of Title I of  ERISA,  and the  fiduciary  requirements  of Part 4 of Title I of
ERISA by  reason  of the  exclusions  afforded  plans  which  are  unfunded  and
maintained  by an  employer  primarily  for the  purpose of  providing  deferred
compensation for a select group of management or highly compensated employees.


                                   ARTICLE II

                                   ARTICLE IV

                          CONTRIBUTIONS AND ACCOUNTING

          4.1  Deferred   Compensation.   An  Eligible  Employee  may  become  a
Participant and make Automatic  Deferrals,  Basic Deferrals and/or Discretionary
Deferrals, as specified by the Board, by electing to defer Compensation pursuant
to   a   Deferred    Compensation/Participation    Agreement.    Such   Deferred
Compensation/Participation  Agreement  shall be entered  into prior to the first
day of the Period of Service for which the  Deferred  Compensation/Participation
Agreement is  effective  or, in the case of an Employee who is hired during such
Plan Year and  designated as eligible to  participate  in the Plan for such Plan
Year, such Deferred  Compensation/Participation  Agreement shall be entered into
within 30 days after such date of hire and shall only be effective  with respect
to Compensation earned after the date such Deferred Compensation/  Participation
Agreement  is  received  by  the   Administrator.   A   Participant's   Deferred
Compensation/Participation  Agreement  shall only be effective with respect to a
single Plan Year and shall be  irrevocable  for the  duration of such Plan Year.
Deferral elections for each subsequent Plan Year of participation  shall be made
pursuant to new Deferred Compensation/Participation Agreements.

                  (a) Basic  Deferrals.  Prior to each  Period of  Service,  the
Board shall determine the maximum  percentage of Compensation that each Eligible
Employee  may  elect  to  defer  under  the  Plan  as a Basic  Deferral  for the
immediately following Period of Service. An Eligible Employee shall only be able
to make Basic Deferrals under the Plan if he has elected to defer the 401(k) Max
under the 401(k) Plan.





                                       6
<PAGE>


                  (b)  Automatic  Deferral.  Effective  January  1,  1998,  such
Eligible  Employee  may  elect  to  automatically   have  a  percentage  of  his
Compensation deferred under the Plan as an Automatic Deferral when his deferrals
under the 401(k) Plan reach the 401(k) Max.  An Eligible  Employee  may elect to
make  Automatic  Deferrals  in addition to or in lieu of Basic  Deferrals  under
Section 4.1(a).

                  (c) Discretionary Deferrals.  Prior to each Period of Service,
the Board shall  determine  the maximum  percentage  of  Compensation  that each
Eligible Employee may elect to defer under the Plan as a Discretionary  Deferral
for the immediately  following  Period of Service.  The requirement to defer the
401(k) Max under the 401(k) Plan shall not apply with  respect to the ability to
make Discretionary Deferrals under the Plan.

                  (d) Limit on  Deferrals.  A  Participant  may only make  Basic
Deferrals  and  Automatic  Deferrals  to the Plan if he has elected to defer the
401(k) Max under the 401(k) Plan. The maximum amount of Automatic  Deferrals and
Basic  Deferrals  made by such a Participant,  for any calendar year,  shall not
exceed ten percent of his  Compensation for the calendar year, as reduced by the
401(k) Max for such  year.  Notwithstanding  the  preceding  provisions  of this
Section  4.1(d),  for the first  Period of Service in which an Employee  becomes
eligible to  participate  in the Plan,  the Eligible  Employee may elect to make
Basic  Deferrals  or  Automatic  Deferrals  up  to  the  maximum  percentage  of
Compensation  permitted  by the Board for that Period of Service with respect to
Compensation for services  performed  subsequent to the election.  The amount of
Discretionary  Deferrals a Participant  may make to the Plan shall be determined
by the Board.

                  (e) Failure to Elect. If an Eligible Employee does not execute
a Deferred Compensation/Participation  Agreement and elect to defer an amount of
his  Compensation,  for a particular  Period of Service in accordance  with this
Section  4.1,  he may not  participate  in the Plan for that  Period of Service.
Thereafter,  he may  elect to  participate  in the Plan with  respect  to future
Periods of Service, if he is then an Eligible Employee,  by executing a Deferred
Compensation/Participation Agreement in accordance with the requirements of this
Section 4.1 and irrevocably  electing to defer a percentage of his  Compensation
prior to any such future Period of Service.


          4.2 Matching Contributions.  For each calendar year, the Employer will
credit  each   Participant's   Account  with  amounts  that  represent  Matching
Contributions  equal to such percentage,  as determined from time to time by the
Board under the 401(k) Plan, of the Participant's Deferred Compensation Election
for that  calendar  year up to six  percent of the  Participant's  Compensation,
reduced by the amount of employer matching contributions, if any, made on behalf
of the  Participant  to the 401(k)  Plan for that  calendar  year.  No  Matching
Contributions will be made on behalf of the Participant under the Plan until the
maximum amount of employer matching contributions  permitted under the Code have


                                       7
<PAGE>

been made on the Participant's  behalf to the 401(k) Plan. The value of Matching
Contributions  credited to a Participant's  Account will be used, along with the
value of the Participant's  Employer  Discretionary  Contributions,  if any, and
Deferred  Compensation  credited to his Account,  to  determine  his Benefits as
specified herein.

          4.3 Employer Discretionary Contribution. Effective January 1, 1997, an
Employer may contribute hereunder as an Employer Discretionary  Contribution for
a Plan Year such amount,  if any, as shall be  determined by the Board from time
to time.  The  Employer  Discretionary  Contribution,  if any,  may be made with
respect to active Participants and inactive  Participants,  as determined by the
Board. Amounts representing Employer Discretionary Contributions,  if any, for a
Plan Year shall be determined and credited to each Participant's Account at such
times and in such  amounts as  determined  by the Board for the Plan Year.  Such
contributions  shall  be  vested  at such  time as  determined  by the  Board in
accordance with the resolutions of the Board authorizing the  contribution.  The
value  of  Employer  Discretionary  Contributions  credited  to a  Participant's
Account  will be used,  along  with  the  value  of the  Participant's  Matching
Contributions,  if any, and Deferral  Compensation  credited to his Account,  to
determine his Benefits as specified herein.

          4.4 Vesting. Participants shall be 100 percent vested in the Automatic
Deferrals,  Basic Deferrals and Discretionary Deferrals credited to his Account,
including the earnings thereon if such amounts are invested  pursuant to Section
7.2 hereof.  A  Participant  will become  vested in the  Employer  Discretionary
Contributions,  if any, credited to his Account,  including the earnings thereon
if such amounts are invested  pursuant to Section  7.2, in  accordance  with the
resolutions of the Board authorizing the contribution. A Participant will become
vested in the  Matching  Contributions  credited to his Account,  including  the
earnings thereon if such amounts are invested pursuant to Section 7.2 hereof, as
follows:

               Year of Service            Vested Percentage
          --------------------------- --------------------------

                 less than 2                      0

              2 but less than 3                  20%

              3 but less than 4                  40%

              4 but less than 5                  60%

              5 but less than 6                  80%

                  6 or more                     100%



In  addition,  a  Participant  will  become 100 percent  vested in the  Employer
Discretionary Contributions,  if any, and Matching Contributions credited to his
Account, including the earnings thereon if such amounts are invested pursuant to
Section  7.2 hereof,  regardless  of his Years of Service  upon the  occurrence,
while  employed by an Employer,  of his death or  Disability,  attainment of his
Normal Retirement Age or termination of the Plan.

          4.5  Accounting for Deferred  Compensation.  The  Administrator  shall
establish and maintain an individual  Account under the name of each Participant
under the Plan. Each Account shall be adjusted at least quarterly to reflect the
Basic  Deferrals,   Automatic  Deferrals,   Discretionary  Deferrals,   Matching
Contributions and Employer Discretionary Contributions credited thereto, if any;
earnings credited on such Basic Deferrals,  Automatic  Deferrals,  Discretionary
Deferrals,  Matching  Contributions  and  Employer  Discretionary  Contributions
pursuant to Section 7.1; and any payment of amounts  attributable  to such Basic
Deferrals, Automatic Deferrals,  Discretionary Deferrals, Matching Contributions
and  Employer  Contributions  under this Plan.  The amounts of Basic  Deferrals,
Automatic  Deferrals,   Discretionary  Deferrals,  Matching  Contributions,  and
Employer  Discretionary  Contributions  shall be credited  to the  Participant's
Account  at  such  time  as  such  Compensation  would  have  been  paid  to the
Participant had the Participant not elected to defer such Compensation  pursuant
to the terms and  provisions  of the Plan.  Each such Account  shall be credited
with  earnings  and/or  losses  computed  pursuant  to Section 7.1 in the manner
specified by Section 7.1. In the sole discretion of the Administrator, more than
one Account may be established for each Participant to facilitate record keeping
convenience  and  accuracy.  Each such Account shall be credited and adjusted as
provided in this Plan.  Amounts credited to such Accounts shall be held with the
general assets of the Company.

         Establishment  and  maintenance  of a separate  Account or Accounts for
each  Participant  shall not be  construed  as giving any person any interest in
assets of the  Company  or an  Affiliate,  or a right to  payment  other than as
provided hereunder. Such Accounts shall be maintained until all amounts credited
as such  Account  have  been  distributed  in  accordance  with  the  terms  and
provisions of this Plan.

          4.6 Plan  Benefits.  Subject to the vesting  provisions of Section 4.4
hereof and the provisions of Article V, the Benefits to which a Participant and,
if applicable,  his Beneficiary shall be entitled under the Plan will consist of
Deferred  Compensation,   Employer  Discretionary   Contributions  and  Matching
Contributions  credited to such Participant's Account, plus earnings thereon and
less losses allocable  thereto,  if any,  attributable to the investment of such
amounts pursuant to Section 7.2 hereof.


                                    ARTICLE V

                            DISTRIBUTION OF BENEFITS


         5.1 Payment of Benefits. The amount credited to a Participant's Account
pursuant to Article IV hereof,  to the extent  vested  pursuant to Section  4.4,
shall be payable to the  Participant  or, if applicable,  to his  Beneficiary in
accordance  with the  provisions of this Article V. If the Employer has obtained
life insurance  policies as a reserve for the discharge of its obligations under


                                       9
<PAGE>

the Plan, the Employer acting through its governing body may, in its discretion,
distribute  any such policy to a  Participant  when the  Participant's  Benefits
become payable to satisfy all or a portion of the  Employer's  obligation to the
Participant hereunder. Unless paid earlier pursuant to Section 5.2, payment of a
Participant's  Benefit under the Plan shall  commence in the form elected by the
Participant  pursuant  to  Section  5.3  hereof  within  30 days  following  the
Participant's  death,  Disability or other  termination  of employment  with the
Employer.

         5.2 Timing of Certain Payments.  Notwithstanding any other provision of
this Plan to the  contrary,  the Board  shall have the right to pay  Benefits to
Participants  prior  to the  time  such  Benefits  otherwise  would  be  payable
hereunder  if the Board in good faith  determines  that either of the  following
conditions or events has occurred:

                  (a)  Change  in  Circumstances.   A  change  in  circumstances
relating to the operation of the Plan or the taxation of  Participants,  arising
from a change  in the  federal  or  applicable  state  tax or  revenue  laws,  a
published  ruling or similar  announcement by the Internal  Revenue  Service,  a
regulation issued by the Secretary of the Treasury,  a change in securities laws
or  regulations,  the  issuance  of an  advisory  opinion,  regulation  or other
published  position  by the  Department  of  Labor,  or a change  in  accounting
requirements which causes (i) Participants to be taxable on their Benefits prior
to the time Benefits otherwise would be payable  hereunder,  (ii) the Plan to be
considered  as funded  for  purposes  of Title I of ERISA,  or (iii) a  material
change regarding the tax or financial accounting consequences of maintaining the
Plan to the Company or any Employer.

                  (b)  An  unforeseeable   emergency  of  the  Participant.   An
unforeseeable  emergency  is a  severe  financial  hardship  to the  Participant
resulting from a sudden and unexpected illness or accident of the Participant or
a dependent (as defined in section 152(a) of the Code) of the Participant,  loss
of the Participant's  property due to casualty,  or other similar  extraordinary
and unforeseeable circumstances arising as a result of events beyond the control
of the Participant.  An unforeseeable  emergency will not exist, however, if the
emergency may be relieved through  reimbursement or compensation by insurance or
otherwise,  or by liquidation  of the  Participant's  assets,  to the extent the
liquidation of such assets would not itself cause a severe  financial  hardship.
In  addition,  an  unforeseeable  emergency  will not exist,  as a result of the
Participant's  need to send a child to college or desire to purchase a home. The
amount distributed to a Participant on account of an unforeseeable emergency may
not exceed the amount reasonably necessary to satisfy such emergency.

         5.3  Form of  Payment.  Each  Participant  may  elect  on his  Deferred
Compensation/Participation  Agreement  whether his Benefits  will be paid in the
form of a single sum payment or substantially equal monthly  installments over a
period of 60 months.  For this purpose,  the Participant's  most recent Deferred
Compensation/Participation  Agreement will be  controlling.  The Participant may
change  the form in which  his  Benefits  will be paid at any  time  before  the
one-year period ending on the date on which payment of his Benefits commence and
once  payments  commence,  the  form  of  payment  shall  be  irrevocable.  If a


                                      10
<PAGE>

Participant has not elected a form of payment for his Benefits  pursuant to this
Section 5.3, the Participant's Benefits will be paid in a single sum payment. If
such Participant is receiving  installment  payments hereunder and dies prior to
the  payment  of  all  monthly  installments,   the  remaining  portion  of  the
Participant's  Benefits will continue to be paid in monthly  installments to his
Beneficiary for the remaining  installment  period in the same amount and manner
as they would have been paid to the Participant.

         5.4  Designation  of  Beneficiary.  Each  Participant  must designate a
Beneficiary to receive his Benefits in the event of his death, by completing his
Deferred   Compensation/Participation   Agreement   and   filing   it  with  the
Administrator.   The  Administrator  will  recognize  the  most  recent  written
Beneficiary  designation on file prior to a Participant's death. If a designated
Beneficiary  is not  living  at the time of the  Participant's  death,  then the
Administrator  will pay  Participant's  Benefits to the  Participant's  personal
representative,  executor,  or  administrator,  as specified by the  appropriate
legal  jurisdiction.  Any such payment to the  Participant's  Beneficiary or, if
applicable,  to his personal  representative,  executor or  administrator  shall
operate as a complete  discharge of all obligations of the Administrator and the
Employer to the extent of the payment so made.


                                   ARTICLE VI

                               PAYMENT LIMITATIONS

          6.1 Payment Due an Incompetent.  If the Administrator  shall find that
any person to whom any  payment is payable  under the Plan is unable to care for
his affairs  because of mental or physical  illness,  accident or death, or is a
minor,  any payment due (unless a prior claim therefor shall have been made by a
duly appointed guardian, committee or other legal representative) may be paid to
the spouse,  a child, a parent,  a brother or sister or any person deemed by the
Administrator, in its sole discretion, to have incurred expenses for such person
otherwise   entitled  to  payment,   in  such  manner  and  proportions  as  the
Administrator may determine.  Any such payment shall be a complete  discharge of
the  liabilities of the Employer under this Plan, and the Employer shall have no
further obligation to see to the application of any money so paid.

          6.2 Spendthrift Clause. No right, title or interest of any kind in the
Plan shall be transferable or assignable by any Participant or Beneficiary or be
subject  to  alienation,  anticipation,  encumbrance,  garnishment,  attachment,
execution or levy of any kind, whether voluntary or involuntary,  nor subject to
the debts, contracts,  liabilities,  engagements, or torts of the Participant or
Beneficiary.  Any attempt to alienate,  anticipate,  encumber,  sell,  transfer,
assign,  pledge,  garnish,  attach or  otherwise  subject to legal or  equitable
process or encumber or dispose of any interest in the Plan shall be void.

                                   ARTICLE VII

                                     FUNDING

           7.1  Funding.  All Benefits under this Plan shall be paid or provided
directly by the Employer.  Such  Benefits  shall be general  obligations  of the
Employer  which  shall not  require  the  segregation  of any funds or  property
therefor.

         Notwithstanding the foregoing,  in the discretion of the Employer,  the
Employer's   obligations  hereunder  may  be  satisfied  from  a  grantor  trust
established by the Employer, the terms of which will be substantially similar to
the terms of the model trust issued by the Internal  Revenue  Service in Revenue
Procedure 92-64, from an escrow account  established at a bank or trust company,
or from an insurance contract or contracts owned by the Employer.  The assets of
any such trust,  escrow account and any such insurance policy shall continue for
all  purposes  to be a part of the  general  funds  of the  Employer,  shall  be
considered  solely a means  to  assist  the  Employer  to meet  its  contractual
obligations  under this Plan and shall not create a funded  account or  security
interest  for the benefit of any  Participant  under this Plan.  All such assets
shall be subject to the claims of the general  creditors  of the Employer in the
event the Employer is Insolvent.

         If a single trust or other funding  vehicle is established as a reserve
for the obligations hereunder of more than one Employer,  the assets of any such
trust or funding vehicle shall, to the extent attributable to contributions made
by a particular  Employer,  be subject to the claims of the general creditors of
that Employer in the event such Employer is Insolvent, and each Employer will be
treated as a separate grantor to the extent of its participation in any trust so
established. To the extent that any person acquires a right to receive a payment
from an Employer  under the Plan,  such right shall be no greater than the right
of any unsecured general creditor of that Employer.

           7.2 Investments. If a trust is established as provided for in Section
7.1,  earnings and/or losses of the trust  attributable to amounts credited to a
Participant's   Account  shall  increase  or,  if   applicable,   decrease  such
Participant's  Account for purposes of determining  the  Participant's  Benefits
payable hereunder.


                                  ARTICLE VIII

                                 ADMINISTRATION

            8.1 Authority of the  Administrator.  The  Administrator  shall have
full power and authority to interpret,  construe and  administer  the Plan.  The
Administrator's  interpretation and construction  hereof, and actions hereunder,
including any determination of the amount or recipient of any payment to be made
under the Plan,  shall be binding  and  conclusive  on all  persons  and for all
purposes. In addition, the Administrator may employ attorneys,  accountants, and


                                       12
<PAGE>

other professional advisors to assist the Administrator in its administration of
the Plan. The Company shall pay the reasonable fees of any such advisor employed
by the  Administrator.  To the extent permitted by law, the  Administrator,  any
member of the Board and any  employee of an Employer  shall not be liable to any
person for any action taken or omitted in connection with the interpretation and
administration  of the Plan unless  attributable to his own wilful misconduct or
lack of good faith.

            8.2 Claims  Procedure.  The  Administrator  shall be responsible for
administering  claims for  Benefits  under the Plan  pursuant to the  procedures
contained in this Section 8.2. All communications  from the Administrator to the
claimant  shall  be  written  in a manner  calculated  to be  understood  by the
claimant. All interpretations, determinations and decisions by the Administrator
in respect of any matter hereunder will be final,  conclusive,  and binding upon
the Employer,  Participants,  Eligible Employees, Employees,  Beneficiaries, and
all other persons claiming an interest in the Plan.

                  (a) Claim for  Benefits.  In the event that  Benefits  are not
paid to a Participant  (or to his  Beneficiary in the case of the  Participant's
death) and such  claimant  believes he is entitled to receive  Benefits,  then a
written  claim  must be made to the  Administrator  within 60 days from the date
payments are refused.  The  Administrator  will review the written claim, and if
the claim is denied  in whole or in part,  the  Administrator  will  provide  in
writing  within 90 days of receipt of the claim the  specific  reasons  for such
denial,  reference to the pertinent provisions of the Plan upon which the denial
is based, and a description of any additional material or information  necessary
to perfect the claim.  Such written notice will further  indicate the additional
steps to be taken by the  claimant  if a further  review of the claim  denial is
desired,  including a statement  that the claimant may (i) request a review upon
written application to the Administrator,  (ii) review pertinent plan documents,
and (iii) submit issues and comments in writing.  If notice of the denial is not
furnished  in  accordance  with the above  procedure,  the claim shall be deemed
denied and the claimant shall be permitted to proceed with the review  procedure
described  in  Section  8.2(b)  below.  A claim  will be  deemed  denied  if the
Administrator fails to take any action within the said 90-day period.

                  (b) Request for Review. A request by the claimant for a review
of the denied claim must be delivered to the Administrator  within 60 days after
receipt by such claimant of written notification of the denial of such claim (or
the date that the claim is deemed denied).  The  Administrator  shall, not later
than 60 days  after  receipt  of a request  for a review,  make a  determination
concerning the claim. A written  statement  stating the decision on review,  the
specific  reasons for the decision,  and the specific  provisions of the Plan on
which the decision is based shall be mailed or delivered to the claimant  within
such  60-day  period.  If the  decision  on review is not  furnished  within the
appropriate time, the claim shall be deemed denied on review.

            8.3 Cost of  Administration.  The cost of this Plan and the expenses
of administering the Plan shall be paid by the Employer.

            8.4   Limitations  on  Plan   Administration.   No  person  to  whom
discretionary  authority is granted  hereunder shall vote or act upon any matter
involving his own rights, benefits or participation in the Plan.


                                   ARTICLE IX

                       OTHER BENEFIT PLANS OF THE COMPANY

          9.1  Other  Plans.  Nothing  contained  in this Plan  shall  prevent a
Participant  prior to his death,  or his spouse or other  Beneficiary  after his
death, from receiving, in addition to any payments provided for under this Plan,
any payments provided for under any other plan or benefit program of the Company
or an Affiliate,  or which would otherwise be payable or  distributable  to him,
his surviving  spouse or Beneficiary  under any plan or policy of the Company or
otherwise.  Nothing in this Plan shall be construed as preventing the Company or
any of its Affiliates from  establishing  any other or different plans providing
for current or deferred compensation for employees. Unless specifically provided
otherwise in any plan of the Company  intended to "qualify" under section 401 of
the Code,  Compensation deferrals made under this Plan shall constitute earnings
or compensation for purposes of determining contributions or benefits under such
qualified plan.


                                    ARTICLE X

                      AMENDMENT AND TERMINATION OF THE PLAN

        10.1 Amendment. The Board shall have the right to amend this Plan at any
time  and  from  time to  time,  including  a  retroactive  amendment.  Any such
amendment  shall become  effective  upon the date stated  therein,  and shall be
binding on all Employers  then  participating  in the Plan,  except as otherwise
provided in such amendment;  provided, however, that no such action shall affect
any  Benefit  adversely  to  which  a  Participant  would  be  entitled  had his
employment been terminated immediately before such amendment was effective.

        10.2  Termination.  The Company has established  this Plan with the bona
fide intention and expectation  that from year to year it will deem it advisable
to continue it in effect.  However, the Board, in its sole discretion,  reserves
the right to terminate the Plan in its entirety at any time; provided,  however,
that no such action  shall affect any Benefit  adversely to which a  Participant
would be entitled had his employment  been  terminated  immediately  before such
termination was effective.





                                       14

        10.3   Continuation.   The  Company   intends  to  continue   this  Plan
indefinitely,  but  nevertheless  assumes no contractual  obligation  beyond the
promise to pay the benefits described in this Plan.


                                   ARTICLE XI

         11.1  Rights  Against  Employer.  The Plan  shall not be deemed to be a
consideration  for, or an inducement  for, the employment of any Employee by the
Employer. Nothing contained in the Plan shall be deemed to give any Employee the
right to be  retained in the service of the  Employer or to  interfere  with the
right of the Employer to discharge any Employee at any time,  without  regard to
the effect such discharge may have on any rights under the Plan.

         11.2 Action Taken in Good Faith. To the extent  permitted by ERISA, the

duties and responsibilities  with respect to the establishment or administration

to be taken by them in good faith.

indemnifies  the  Administrator  and each  employee,  officer and director of an
Affiliate to whom  responsibilities are delegated under the Plan against any and
all liabilities and expenses, including attorney's fees, actually and reasonably
incurred by them in connection with any  threatened,  pending or completed legal
action or judicial or administrative proceeding to which they may be a party, or
may  be  threatened  to be  made  a  party,  by  reason  of  any  delegation  of
responsibilities  hereunder,  except with regard to any matters as to which they
shall be adjudged in such action or proceeding to be liable for gross negligence
or willful misconduct in connection therewith.

         11.4  Severability.  In the event that any provision of this Plan shall
be declared  illegal or invalid for any reason,  said  illegality  or invalidity
shall  not  affect  the  remaining  provisions  of this  Plan but shall be fully
severable  and this Plan shall be  construed  and enforced as if said illegal or
invalid provision had never been inserted herein.

 FORM OF INDEMNITY AGREEMENT BETWEEN THE COMPANY AND ITS OFFICERS AND DIRECTORS


AGREEMENT, as of August 20, 1997, (the "Agreement"), between ENSCO International
Incorporated, a Delaware corporation (the "Company"), and (the "Indemnitee").

          WHEREAS,  it is  essential  to the  Company to retain  and  attract as
directors, officers and employees the most capable persons available;

         WHEREAS,  both the Company and Indemnitee  recognize the increased risk
of litigation and other claims being asserted  against  directors,  officers and
employees of public companies in today's environment;

         WHEREAS, the Bylaws of the Company require the Company to indemnify its
directors, officers and employees to the fullest extent permitted by law;

         WHEREAS,  the  Indemnitee  has been serving and continues to serve as a
director, officer or employee of the Company in part in reliance on such Bylaws;
and

         WHEREAS, in recognition of Indemnitee's need for substantial protection
against personal liability in order to enhance Indemnitee's continued service to
the Company in an effective  manner and  Indemnitee's  reliance on the aforesaid
Bylaws,  and in part to provide Indemnitee with specific  contractual  assurance
that the  protection  promised by such Bylaws will be  available  to  Indemnitee
(regardless  of, among other  things,  any  amendment to or  revocation  of such
Bylaws or any change in the  composition of the Company's  Board of Directors or
acquisition  transaction relating to the Company), the Company wishes to provide
in this  Agreement for the  indemnification  of and the advancing of expenses to
Indemnitee  to the  fullest  extent  permitted  by law and as set  forth in this
Agreement,  and,  to the  extent  insurance  is  maintained,  for the  continued
coverage of Indemnitee  under the Company's  directors' and officers'  liability
insurance policies.

 NOW, THEREFORE,  in consideration of the premises and of Indemnitee  continuing
to serve the Company directly or, at its request,  with another enterprise,  and
intending to be legally bound hereby, the parties hereto agree as follows:

 1.      Certain Definitions:

         (a) Change in Control:  For  purposes of this  Agreement,  a "Change in
Control" shall mean any of the following events:

                  (i) An  acquisition  (other than directly from the Company) of
any voting  securities of the Company (the "Voting  Securities") by any "Person"
[as the  term  person  is used for  purposes  of  Section  13(d) or 14(d) of the
Securities  Exchange Act of 1934, as amended (the "1934 Act")] immediately after
which such Person has "Beneficial  Ownership"  (within the meaning of Rule 13d-3


                                       1
<PAGE>

promulgated under the 1934 Act) of fifteen percent (15%) or more of the combined
voting power of the Company's  then  outstanding  Voting  Securities;  provided,
however,  that in determining  whether a Change in Control has occurred,  Voting
Securities  which are acquired in a "Non-Control  Acquisition"  (as  hereinafter
defined)  shall not  constitute  an  acquisition  which  would cause a Change in
Control.  A  "Non-Control  Acquisition"  shall  mean  an  acquisition  by (1) an
employee benefit plan (or a trust forming a part thereof)  maintained by (x) the
Company or (y) any corporation or other person of which a majority of its voting
power  or its  equity  securities  or  equity  interest  is  owned  directly  or
indirectly by the Company (a  "Subsidiary"),  (2) the Company or any Subsidiary,
or (3) any Person in connection with a "Non-Control Transaction" (as hereinafter
defined).

                  (ii) The  individuals  who, as of August 18, 1997, are members
of the Board (the "Incumbent Board") cease for any reason to constitute at least
two-thirds of the Board; provided,  however, that if the election, or nomination
for election by the Company's stockholders,  of any new director was approved by
a vote of at least two-thirds of the Incumbent  Board,  such new director shall,
for  purposes of this  Agreement,  be  considered  as a member of the  Incumbent
Board;  provided  further,  however,  that no  individual  shall be considered a
member of the Incumbent Board if such individual  initially  assumed office as a
result of either an actual or  threatened  "Election  Contest" (as  described in
Rule  14a-11  promulgated  under  the 1934 Act) or other  actual  or  threatened
solicitation  of proxies or consents by or on behalf of a Person  other than the
Board (a "Proxy Contest") including by reason of any agreement intended to avoid
or settle any Election Contest or Proxy Contest; or

                  (iii) Approval by stockholders of the Company of:

                         (A) a merger or  consolidation  involving  the  Company
     unless (1) the stockholders of the Company, immediately before such merger,
consolidation  or  reorganization,   own,  directly  or  indirectly  immediately
following such merger,  consolidation or reorganization,  at least sixty percent
(60%) of the combined voting power of the outstanding  voting  securities of the
corporation  resulting from such merger or consolidation or reorganization  (the
"Surviving Corporation") in substantially the same proportion as their ownership
of the Voting  Securities  immediately  before  such  merger,  consolidation  or
reorganization,  (2) the  individuals  who were members of the  Incumbent  Board
immediately  prior to the execution of the agreement  providing for such merger,
consolidation or reorganization constitute at least two-thirds of the members of
the board of directors of the  Surviving  Corporation,  and (3) no Person (other
than the  Company,  any  Subsidiary,  any  employee  benefit  plan (or any trust
forming a part thereof) maintained by the Company, the Surviving  Corporation or
any  Subsidiary,   or  any  Person  who,   immediately  prior  to  such  merger,
consolidation  or  reorganization  had Beneficial  Ownership of fifteen  percent
(15%)  or  more  of the  then  outstanding  Voting  Securities)  has  Beneficial
Ownership of fifteen  percent (15%) or more of the combined  voting power of the
Surviving  Corporation's  then  outstanding  voting  securities.  A  transaction
described  in  clauses  (1)  through  (3)  shall  herein  be  referred  to  as a
"Non-Control Transaction;"

                                       2
<PAGE>

                           (B) A  complete  liquidation  or  dissolution  of the
Company; or

                           (C) An agreement for the sale or other disposition of
all or substantially  all of the assets of the Company to any Person (other than
a transfer to a Subsidiary).

Notwithstanding the foregoing,  a Change in Control shall not be deemed to occur
solely because any Person (the "Subject Person") acquired  Beneficial  Ownership
of more than the  permitted  amount of the  outstanding  Voting  Securities as a
result of the acquisition of Voting Securities by the Company which, by reducing
the number of Voting Securities  outstanding,  increases the proportional number
of shares Beneficially Owned by the Subject Person, provided that if a Change in
Control would occur (but for the operation of this  sentence) as a result of the
acquisition  of  Voting  Securities  by  the  Company,   and  after  such  share
acquisition by the Company,  the Subject Person becomes the Beneficial  Owner of
any  additional  Voting  Securities  which  increases the percentage of the then
outstanding Voting Securities  Beneficially Owned by the Subject Person,  then a
Change in Control shall occur.

         (b)  Claim:  any  threatened,  pending  or  completed  action,  suit or
proceeding,  whether civil, criminal,  administrative or investigative or other,
including,  without  limitation,  an  action  by or in the  right  of any  other
corporation of any type or kind, domestic or foreign, or any partnership,  joint
venture, trust, employee benefit plan or other enterprise, whether predicated on
foreign, federal, state or local law and whether formal or informal.

         (c) Expenses:  include attorney's fees and all other costs, charges and
expenses paid or incurred in connection with investigating,  defending,  being a
witness in or participating in (including on appeal), or preparing to defend, be
a witness in or participate in any Claim relating to any Indemnifiable Event.

         (d)  Indemnifiable  Event: any event or occurrence  related to the fact
that Indemnitee is or was or has agreed to become a director, officer, employee,
agent or fiduciary  of the Company,  or is or was serving or has agreed to serve
in any  capacity,  at the  request  of the  Company,  in any other  corporation,
partnership, joint venture, employee benefit plan, trust or other enterprise, or
by reason of anything done or not done by Indemnitee in any such capacity.

         (e)  Potential Change of Control: shall be deemed to have occurred if

                  (i) the Company enters into an agreement or  arrangement,  the
consummation of which would result in the occurrence of a Change in control; or

                  (ii) the Board  adopts a resolution  to the effect  that,  for
purposes of this Agreement, a Potential Change in control has occurred.

         (f)  Voting Securities:  any  securities  of  the  Company  which  vote
 generally in the election of directors.

                                       3

2.       Basic Indemnification Arrangement:

         (a) In the event Indemnitee was, is or becomes a party to or witness or
other participant in, or is threatened to be made a party to or witness or other
participant  in,  a  Claim  by  reason  of  (or  arising  in  part  out  of)  an
Indemnifiable  Event, the Company shall indemnify  Indemnitee (without regard to
the negligence or other fault of the Indemnitee) to the fullest extent permitted
by applicable law, as soon as practicable but in no event later than thirty days
after written demand is presented to the Company,  against any and all Expenses,
judgments,  fines,  penalties,  excise  taxes and amounts  paid or to be paid in
settlement  (including  all  interest,  assessments  and other  charges  paid or
payable in connection  with or in respect of such  Expenses,  judgments,  fines,
penalties,  excise  taxes or amounts paid or to be paid in  settlement)  of such
Claim. If Indemnitee makes a request to be indemnified under this Agreement, the
Board of Directors  (i) acting by a majority  vote of the  directors who are not
parties to the Claim with respect to an Indemnifiable Event, even if less than a
quorum,  (ii) acting by a committee  of such  directors  appointed by a majority
vote of such  directors,  even if less than a quorum,  or (iii)  acting  upon an
opinion in writing of independent legal counsel,  if there are no such directors
of if such directors so direct ("Board  Action")  shall,  as soon as practicable
but in no event  later  than  thirty  days after such  request,  authorize  such
indemnification.   Notwithstanding   anything  in  the   Amended  and   Restated
Certificate   of   Incorporation   of   the   Company   (the   "Certificate   of
Incorporation"),  the Bylaws of the Company or this  Agreement to the  contrary,
following a Change in Control,  Indemnitee  shall,  unless prohibited by law, be
entitled to  indemnification  pursuant to this Agreement in connection  with any
Claim initiated by Indemnitee.

         (b) Notwithstanding  anything in the Certificate of Incorporation,  the
Bylaws or this  Agreement to the contrary,  if so requested by  Indemnitee,  the
Company  shall  advance  (within two business  days of such request) any and all
Expenses  relating to a Claim to  Indemnitee  (an "Expense  Advance"),  upon the
receipt of a written  undertaking  by or on behalf of  Indemnitee  to repay such
Expense Advance if a judgment or other final adjudication  adverse to Indemnitee
(as to which all  rights or appeal  therefrom  have been  exhausted  or  lapsed)
establishes  that  Indemnitee,  with respect to such Claim,  is not eligible for
indemnification.

         (c) Notwithstanding  anything in the Certificate of Incorporation,  the
Bylaws or this  Agreement to the  contrary,  if Indemnitee  has commenced  legal
proceedings in a court of competent  jurisdiction to secure a determination that
Indemnitee should be indemnified under this Agreement, the Bylaws of the Company
or  applicable  law, any Board Action or  Arbitration  (as defined in Section 3)
that  Indemnitee  would not be permitted to be  indemnified  in accordance  with
Section 2(a) of this Agreement shall not be binding.  If there has been no Board
Action  or  Arbitration,  or if Board  Action  or  Arbitration  determines  that
Indemnitee would not be permitted to be indemnified, in any respect, in whole or
in part, in accordance  with Section 2(a) of this  Agreement,  Indemnitee  shall
have the right to commence  litigation  in the court which is hearing the action
or proceeding  relating to the Claim for which  indemnification  is sought or in
any court in the States of Delaware or Texas having subject matter  jurisdiction
thereof and in which  venue is proper  seeking an initial  determination  by the
court or challenging any such Board Action or Arbitration or any aspect thereof,


                                       4
<PAGE>

and the Company thereby consents to service of process and to appear in any such
proceeding. Any Board Action not followed by Arbitration or such litigation, and
any Arbitration not followed by such litigation, shall be conclusive and binding
on the Company and Indemnitee.

3.       Change in Control.

         The Company agrees that if there is a Change in Control, Indemnitee, by
giving  written notice to the Company and the American  Arbitration  Association
(the  "Notice"),  may require that any  controversy  or claim  arising out of or
relating  to  this  Agreement,  or the  breach  thereof,  shall  be  settled  by
arbitration (the "Arbitration"),  in Dallas, Texas, in accordance with the Rules
of the American Arbitration  Association (the "Rules"). The Arbitration shall be
conducted by a panel of three arbitrators  selected in accordance with the Rules
within thirty days of delivery of the Notice. The decision of the panel shall be
made as soon as practicable  after the panel has been selected,  and the parties
agree to use their reasonable efforts to cause the panel to deliver its decision
within ninety days of its selection. The Company shall pay all fees and expenses
of the  Arbitration.  The  Arbitration  shall be  conclusive  and binding on the
Company  and  Indemnitee,  and  Indemnitee  may  cause  judgment  upon the award
rendered  by the  arbitrators  to be  entered in any court  having  jurisdiction
thereof;  provided,  however,  that any  Arbitration  shall  have no  effect  on
Indemnitee's  right to  commence  litigation  pursuant  to Section  2(c) of this
Agreement,  in which case, such Arbitration  shall not be conclusive and binding
on Indemnitee or the Company.

4.       Establishment of Trust.

         In the event of a  Potential  Change in Control or a Change in Control,
the Company shall,  promptly upon written request by Indemnitee,  create a Trust
for the benefit of  Indemnitee  and from time to time,  upon written  request of
Indemnitee to the Company,  shall fund such Trust in an amount,  as set forth in
such request,  sufficient to satisfy any and all Expenses reasonably anticipated
at  the  time  of  each  such  request  to  be  incurred  in   connection   with
investigating,   preparing  for  and   defending   any  claim   relating  to  an
Indemnifiable Event, and any and all judgments,  fines, penalties and settlement
amounts of any and all claims  relating to an  Indemnifiable  Event from time to
time actually paid or claimed,  reasonably  anticipated  or proposed to be paid.
The terms of the Trust shall provide that upon a Change in Control:

                  (i) the Trust  shall not be revoked or the  principal  thereof
invaded, without the written consent of Indemnitee;

                  (ii) the Trustee shall advance,  within two business days of a
request by Indemnitee, any and all Expenses to Indemnitee, not advanced directly
by the Company to  Indemnitee  (and  Indemnitee  hereby  agrees to reimburse the
Trust  under the  circumstances  under  which  Indemnitee  would be  required to
reimburse the Company under Section 2(b) of this Agreement);

                                       5
<PAGE>

                   (iii) the Trust shall continue be to funded by the Company in
accordance with the funding obligation set forth above;

                  (iv) the Trustee shall  promptly pay to Indemnitee all amounts
for which  Indemnitee  shall be  entitled  to  indemnification  pursuant to this
Agreement or otherwise; and

                  (v) all  unexpended  funds in such Trust  shall  revert to the
Company upon a final  determination by Board Action or Arbitration or a court of
competent  jurisdiction,  as the case may be,  that  Indemnitee  has been  fully
indemnified  under the terms of this  Agreement.  The Trustee shall be chosen by
Indemnitee.  Nothing in this  Section 4 shall  relieve the Company of any of its
obligations under this Agreement.

5.       Indemnification for Additional Expenses.

         The Company  shall  indemnify  Indemnitee  against any and all expenses
(including  attorney's fees) and, if requested by Indemnitee,  shall (within two
business days of such request)  advance such expenses to  Indemnitee,  which are
incurred  by  Indemnitee  in  connection  with any claim  asserted  by or action
brought by Indemnitee for:

                  (i)  indemnification  or advance  payment of  Expenses  by the
Company  under this  Agreement or any other  agreement  or Company  Bylaw now or
hereafter in effect relating to Claims for Indemnifiable Events and/or

                  (ii) recovery  under any  directors'  and officers'  liability
insurance policies  maintained by the Company,  regardless of whether Indemnitee
ultimately is determined to be entitled to such indemnification, advance expense
payment or insurance recovery, as the case may be.

6.       Partial Indemnity, Etc.

         If Indemnitee is entitled,  under any  provisions of this  Agreement to
indemnification by the Company for some or a portion of the Expenses, judgments,
fines, penalties, excise taxes and amounts paid or to be paid in settlement of a
Claim but not, however,  for all of the total amount thereof,  the Company shall
nevertheless indemnify Indemnitee for the portion thereof to which Indemnitee is
entitled.  Moreover,  notwithstanding any other provision of this Agreement,  to
the extent that  Indemnitee  has been  successful  on the merits or otherwise in
defense of any or all Claims  relating  in whole or in part to an  Indemnifiable
Event  or in  defense  of  any  issue  or  matter  therein,  including,  without
limitation, dismissal without prejudice, Indemnitee shall be indemnified against
any and all Expenses, judgments, fines, penalties, excise taxes and amounts paid
or to be paid in settlement of such Claim. In connection with any  determination
by  Board  Action,  Arbitration  or  a  court  of  competent  jurisdiction  that
Indemnitee  is not  entitled to be  indemnified  hereunder,  the burden of proof
shall be on the Company to establish that Indemnitee is not so entitled.

                                       6
<PAGE>


7.       No Presumption.

         For purposes of this Agreement,  the termination of any claim,  action,
suit or  proceeding,  by judgment,  order,  settlement  (whether with or without
court  approval)  or  conviction,  or  upon a plea of  nolo  contendere,  or its
equivalent,  shall not create a  presumption  that  Indemnitee  did not meet any
particular standard of conduct or have any particular belief or that a court has
determined  that  indemnification  is not  permitted by  applicable  law or this
Agreement.

8.       Contribution.

         In the event that the indemnification provided for in this Agreement is
unavailable to Indemnitee  for any reason  whatsoever,  the Company,  in lieu of
indemnifying Indemnitee,  shall contribute to the amount incurred by Indemnitee,
whether for judgments,  fines,  penalties,  excise taxes,  amounts paid or to be
paid in settlement and/or for Expenses, in connection with any Claim relating to
an  Indemnifiable  Event, in such proportion as is deemed fair and reasonable in
light of all of the  circumstances of such action by Board Action or Arbitration
or by the court before which such action was brought in order to reflect:

                  (i)  the  relative   benefits  received  by  the  Company  and
Indemnitee as a result of the event(s)  and/or  transactions(s)  giving cause to
such action; and/or

                  (ii)  the  relative  fault  of  the  Company  (and  its  other
directors,  officers,  employees and agents) and  Indemnitee in connection  with
such event(s) and/or  transaction(s).  Indemnitee's  right to contribution under
this Section 8 shall be determined in  accordance  with,  pursuant to and in the
same  manner  as,  the  provisions  in  Sections  2 and  3  hereof  relating  to
Indemnitee's right to indemnification under this Agreement.

9.       Notice to the Company by Indemnitee.

         Indemnitee  agrees to promptly notify the Company in writing upon being
served with or having  actual  knowledge of any  citation,  summons,  complaint,
indictment or any other similar document relating to any action which may result
in a claim of indemnification or contribution hereunder.

10.      Non-exclusivity, Etc.

         The rights of the  Indemnitee  hereunder  shall be in  addition  to any
other  rights   Indemnitee   may  have  under  the  Company's   Certificate   of
Incorporation  or Bylaws or the Delaware  General  Corporation Law or otherwise,
and  nothing   herein  shall  be  deemed  to  diminish  or  otherwise   restrict
Indemnitee's  right to  indemnification  under any such other provision.  To the
extent  applicable  law or the  Certificate  of  Incorporation  or the Bylaws of
Company,  as in effect on the date hereof or at any time in the  future,  permit
greater  indemnification  than as provided  for in this  Agreement,  the parties


                                       7
<PAGE>

hereto agree that Indemnitee  shall enjoy by this Agreement the greater benefits
so afforded by such law or  provision of the  Certificate  of  Incorporation  or
Bylaws and this Agreement  shall be deemed amended without any further action by
the Company or Indemnitee to grant such greater  benefits.  Indemnitee may elect
to have Indemnitee's rights hereunder interpreted on the basis of applicable law
in  effect  at the  time of  execution  of this  Agreement,  at the  time of the
occurrence  of the  Indemnifiable  Event  giving  rise to a Claim or at the time
indemnification is sought.

11.      Liability Insurance.

         To the extent the Company  maintains at any time an insurance policy or
policies  providing  directors' and officers'  liability  insurance,  Indemnitee
shall be covered by such policy or  policies,  in  accordance  with its or their
terms,  to the maximum  extent of the coverage  available  for any other Company
director or officer under such insurance policy. The purchase and maintenance of
such insurance  shall not in any way limit or affect the rights and  obligations
of the parties  hereto,  and the execution and delivery of this Agreement  shall
not in any way be construed to limit or affect the rights and obligations of the
Company and/or of the other parties under any such insurance policy.

12.      Period of Limitations.

         No legal  action  shall be  brought  and no  cause of  action  shall be
asserted by or on behalf of the Company or any affiliate of the Company  against
Indemnitee,   Indemnitee's  spouse,  heirs,   executors  or  personal  or  legal
representatives  after the  expiration  of two years from the date of accrual of
such  cause of  action,  and any claim or cause of action of the  Company or its
affiliate  shall be  extinguished  and deemed  released  unless  asserted by the
timely filing of a legal action within such two-year period; provided,  however,
that if any shorter period of  limitations  is otherwise  applicable to any such
cause of action such shorter period shall govern.

13.      Amendments, Etc.

         No supplement,  modification  or amendment of this  Agreement  shall be
binding unless executed in writing by both of the parties  hereto.  No waiver of
any of the  provisions of this Agreement  shall be deemed or shall  constitute a
waiver of any other  provisions  hereof  (whether or not similar) nor shall such
waiver constitute a continuing waiver.

14.      Subrogation.

         In the event of payment  under this  Agreement,  the  Company  shall be
subrogated  to the extent of such payment to all of the rights of recovery  with
respect to such payment of Indemnitee, who shall execute all papers required and
shall do everything  that may be necessary to secure such rights,  including the
