                     Key Energy Group, Inc. and Subsidiaries

    PART I. ITEM 1.  BUSINESS.

    The Company

    Key Energy  Group,  Inc. (the  "Company" or "Key") is a leading  provider of
    well services in the United  States and in  Argentina.  As of June 30, 1997,
    the Company operated a fleet of 523 well service rigs, 437 fluid hauling and
    other  trucks,  and nine  drilling rigs  (including  16 workover  rigs,  six
    trucks,  and 3 drilling rigs in Argentina).  As of June 30, 1997, Key's well
    service and workover rig fleet and fluid  hauling and other truck fleet were
    the second largest and largest fleets, respectively, onshore the continental
    United  States.  The  Company  operates  in  Texas,  New  Mexico,  Oklahoma,
    Michigan,  the  Appalachian  Basin  and  Argentina.  The  Company  generally
    provides a full range of  maintenance  and  workover  services  to major and
    independent  oil and  gas  companies  in all of its  operating  regions.  In
    addition to maintenance and workover  services,  Key also provides  services
    which include the completion of newly drilled  wells,  the  recompletion  of
    existing wells  (including  horizontal  recompletions)  and the plugging and
    abandonment  of wells  at the end of  their  useful  lives.  Other  services
    include oil field fluid transportation,  storage and disposal services, frac
    tank rentals,  fishing and rental tools, wireline services, air drilling and
    hot oiling. In addition, the Company is engaged in contract drilling in West
    Texas and Argentina and owns and produces oil and natural gas in the Permian
    Basin.

    The Company  conducts  operations  through four  wholly-owned  subsidiaries:
    Yale E. Key, Inc.  ("Yale E. Key");  WellTech Eastern, Inc. ("WellTech 
    Eastern");  Odessa Exploration Incorporated ("Odessa Exploration");  and 
    Key Energy Drilling, Inc. d/b/a Clint Hurt Drilling ("Clint Hurt"). In 
    addition,  Key operates in Argentina  through its 63% ownership (wholly-
    owned as of July 1, 1997) of Servicios WellTech,  S.A. ("Servicios"). 
    WellTech Eastern operates through two divisions:  WellTech Mid-Continent 
    Division and WellTech Eastern  Division.  Yale E. Key,  WellTech  Eastern 
    and Servicios  provide oil and gas well services, and Servicios owns 
    contract  drilling  rigs.  Odessa  Exploration is engaged in the production
    of oil and natural gas and Clint Hurt provides contract oil and gas well 
    drilling services in the Permian Basin of West Texas.

    Subsequent Events

    Subsequent  to June 30,  1997,  the  Company  purchased  the  remaining  37%
    interest in Servicios and completed the  acquisition  of four well servicing
    companies  which  collectively  operate 83 well  service and  workover  rigs
    (including six in Argentina), three drilling rigs in Argentina, and 75 fluid
    hauling and other trucks. The Company has also announced, subsequent to June
    30, 1997, five acquisitions of well service companies and one acquisition of
    a drilling  company  which  collectively  operate 153 well service  rigs, 11
    drilling  rigs,  91 fluid  hauling and other trucks and a fishing and rental
    tool business.  These six announced  acquisitions are currently  pending and
    assuming  their  completion,  the Company will have  expanded its  operating
    presence  into  markets it  previously  did not serve,  including  the Rocky
    Mountains,  the Four Corners area, the Hugoton Basin, Northern Louisiana and
    Arkansas.  Upon completion of these pending  acquisitions,  Key's operations
    will include 764 well service and workover rigs, 603 fluid hauling and other
    trucks, 23 drilling rigs and numerous  ancillary  operations.  Following the
    closing of these  acquisitions,  the Company  believes that,  based upon the
    number of active well service rigs and fluid hauling and other trucks,  that
    it would operate at that time, it will be the largest well service  provider
    onshore the  continental  United States and the second  largest well service
    provider in Argentina.

    Growth Strategy

    The  domestic  well  service  rig  and  production   service   industry  has
    historically  been highly  fragmented,  characterized  by a large  number of
    smaller companies which have competed effectively on a local basis in


                                      - 3 -
<PAGE>

         terms of pricing and the quality of services offered.  In recent years,
         many major and independent oil and gas companies have placed increasing
         emphasis upon not only pricing,  but also on safety records and quality
         management  systems of, and the breadth of services  offered by,  their
         vendors, including well servicing contractors. This market environment,
         which requires  significant  expenditures by smaller  companies to meet
         these  increasingly  rigorous  standards,  has forced many smaller well
         servicing companies to sell their operations to larger competitors.  As
         a result, the industry has seen high levels of consolidation  among the
         competing contractors.

         Over the past eighteen months, Key has been a the leading  consolidator
         of  this  industry,   completing  twenty-three   acquisitions  of  well
         servicing  operations  (twenty-eight  including pending  transactions).
         This  consolidation has led to reduced  fragmentation in the market and
         has led to more  predictable  demand for well  services for the Company
         and its competitors. Key's management structure is decentralized, which
         allows for rapid  integration  of  acquisitions  and the  retention  of
         strong local identities of many of the acquired businesses. As a result
         of these and other factors, the Company has developed a growth strategy
         to: (i) identify,  negotiate and consummate additional  acquisitions of
         complementary well servicing  operations,  including rigs, trucking and
         other ancillary services;  (ii)  fully-integrate  acquisitions into the
         Company's decentralized organizational structure and thereby attempt to
         maximize  operating  margins;  (iii) expand business lines and services
         offered by the Company in existing areas of operations; and (iv) extend
         the  geographic  scope and  operating  environments  for the  Company's
         operations.

         Oil Field Services

         The Company  provides a full range of well  service rig  services,  oil
         field  liquid  services  and other  production  services  necessary  to
         maintain  and  workover   producing  oil  and  gas  wells  through  its
         wholly-owned  subsidiaries,  Yale E. Key and  WellTech  Eastern.  These
         services  also  include the  completion  of newly  drilled  wells,  the
         recompletion of existing wells (including horizontal recompletions) and
         the plugging and abandonment of wells at the end of their useful lives.
         Other  services  include  oil field fluid  transportation,  storage and
         disposal  services,  frac  tank  rentals,  fishing  and  rental  tools,
         wireline  services,  air drilling and hot oiling.  The Company has more
         than 750  customers  which are either  major oil and gas  companies  or
         independent  producers  seeking to optimize  performance of oil and gas
         wells.  Although  the mix of oil  and  gas  wells  serviced  varies  by
         particular markets,  approximately  two-thirds of the Company's overall
         business is  attributable  to oil wells.  As of June 30,  1997,  of the
         Company's 523 well service and workover rigs, 273 operate in West Texas
         and New Mexico,  161 in Oklahoma and East Texas, 79 in Michigan and the
         Appalachian Basin, and ten in Argentina.

         Well  Service Rig  Services.  The Company  utilizes its fleet to 
         perform  four major  categories  of service to oil and gas
         operators including:

         Maintenance  Services.  Maintenance services are required on producing
         oil and gas wells to ensure efficient and continuous  operation.  These
         services consist of routine  mechanical  repairs  necessary to maintain
         production  from the well,  such as  repairing  parted  sucker  rods or
         defective down-hole pumps in an oil well, or replacing defective tubing
         in an oil or gas well.  The Company  provides  the well  service  rigs,
         equipment and crews for these maintenance services.  Many of these well
         service rigs also have pumps and tanks (a workover package) that can be
         used for circulating fluids into and out of the well.  Maintenance jobs
         are often performed on a series of wells in proximity to each other and
         typically take less than 48 hours per well.

         Maintenance  services are generally  required  throughout the life of a
         well. The need for these services does not directly depend on the level
         of  drilling  activity  and  is  generally  independent  of  short-term
         fluctuations



                                      - 4 -
<PAGE>


    in oil and gas prices.  Accordingly,  maintenance services are generally the
    most  stable  type of well  service  rig  activity.  The  general  level  of
    maintenance,  however,  is  affected  by  changes  in the  total  number  of
    producing oil and gas wells in the Company's geographic service areas.

    Workover Services.  In addition to periodic  maintenance,  producing oil and
    gas wells  occasionally  require  major  repairs  or  modifications,  called
    "workovers." Workover services include extensions of existing wells to drain
    new formations  either through  deepening well bores or through  drilling of
    horizontal  laterals.  In less extensive  workovers,  the Company's rigs are
    used to seal off depleted zones in existing well bores and access previously
    bypassed  productive  zones.  The  Company's  workover rigs are also used to
    convert producing wells to injection wells for enhanced recovery operations.
    Workover services include major subsurface  repairs such as casing repair or
    replacement,  recovery of tubing and removal of foreign  objects in the well
    bore. These extensive  workover  operations are normally performed by a well
    service  rig with a workover  package , which may  include  rotary  drilling
    equipment,  mud pumps, mud tanks and blowout  preventers  depending upon the
    particular  type of workover  operation.  Most of the Company's well service
    rigs are  designed  for and can be  equipped  to  perform  complex  workover
    operations. A workover may last from a few days to several weeks.

    The demand for workover services is more sensitive to expectations  relating
    to and  changes  in oil and gas  prices  than  the  demand  for  maintenance
    services,  but not as sensitive as the demand for completion services.  When
    oil and gas prices are low, there is little  incentive to perform  workovers
    on wells  to  increase  production  and well  operators  tend to defer  such
    expenditures. As oil and gas prices increase, the level of workover activity
    tends to increase as operators seek to increase  production by enhancing the
    efficiency of their wells.

    Completion  Services.  Completion  services prepare a newly drilled well for
    production.  The completion process may involve selectively  perforating the
    well casing to access producing  zones,  stimulating and testing these zones
    and installing downhole  equipment.  The Company provides a well service and
    workover  package rig to assist in this  completion  process.  Newly drilled
    wells are frequently completed by a well service rig so that an operator can
    minimize  the use of a higher cost  drilling  rig.  The  completion  process
    typically requires a few days to several weeks,  depending on the nature and
    type  of  the  completion,   and  generally  requires  additional  auxiliary
    equipment which the Company provides for an additional fee.

    The demand for well  completion  services  is  directly  related to drilling
    activity levels, which are highly sensitive to expectations  relating to and
    changes  in oil and gas  prices.  During  periods of weak  drilling  demand,
    drilling  contractors  frequently  price well completion work  competitively
    compared to a well  service rig so that the  drilling  rig stays on the job.
    Thus, excess drilling capacity will serve to reduce the amount of completion
    work available to the well servicing industry.

    Plugging and Abandonment Services. Well service rigs and workover equipment
    are also used in the  plugging  and  abandonment  of oil and gas wells  no 
    longer capable of producing in economic quantities. The demand for oil and 
    gas does not significantly affect the demand for well plugging services.

    Liquid  Services.  The Company  provides  vacuum truck  services,  frac tank
    rentals  and  salt  water  disposal   services  which  together  provide  an
    integrated mix of liquid services to well site customers.

    Other Production Services.  The Company provides production services,  which
    include hot oiler unit services, pipeline installation and testing services,
    slickline wire-line services and fishing and rental tool services.

         Shallow Contract Drilling Services

         The Company,  through  Clint Hurt,  owns and operates six drilling rigs
         and provides  contract  drilling services for major and independent oil
         companies,  primarily  in West  Texas.  On August 4, 1997,  the Company
         announced  it had  signed a letter of intent to acquire  BRW  Drilling,
         Inc.  ("BRW") for  approximately  $15.0 million in cash. BRW operates 7
         drilling rigs and related equipment in the Permian Basin of West Texas.
         The closing of the BRW  acquisition  is expected upon  negotiation of a
         definitive   agreement,   completion  of  the  Company's  standard  due
         diligence  and receipt of regulatory  clearances,  if any are required.
         Upon completion, the BRW acquisition will be combined with Clint Hurt's
         drilling  operations  in the  Permian  Basin  of West  Texas  to form a
         thirteen rig shallow drilling  operation.  The Company entered the land
         drilling  business in March 1995 with the  acquisition of four drilling
         rigs from an independent third party and, as the result of the WellTech
         merger,  acquired  two  additional  land  drilling  rigs.  The rigs are
         capable of drilling up to 10,000 feet.

         Production

         The Company is engaged in the  production of oil and natural gas in the
         Permian Basin area of West Texas through its  wholly-owned  subsidiary,
         Odessa Exploration.  Odessa Exploration  acquires and manages interests
         in  producing  oil and gas  properties  for  its  own  account  and for
         drilling   partnerships  it  sponsors.   Odessa  Exploration   acquires
         producing  oil and gas  wells and  related  properties  from  major and
         independent  producers and,  subsequently,  either reworks the acquired
         wells to increase  production or forms drilling ventures for additional
         development  wells.  Odessa  Exploration  operates oil and gas wells on
         behalf  of over  250  working  interest  owners  as well as for its own
         account.

         Foreign Operations

         The Company  provides oil field  services in Argentina  through its 63%
         ownership  (wholly-owned  as of July 1, 1997) of Servicios.  As of June
         30, 1997,  Servicios  owned and operated  ten well  servicing  rigs and
         three  drilling  rigs  in  Argentina  (which  are  currently  idle  and
         undergoing refurbishment). On August 1, 1997, the Company completed the
         acquisition of Kenting Holdings  (Argentina) S.A. ("Kenting") for $10.1
         million in cash. The Kenting assets  included six oilwell service rigs,
         three  drilling rigs and related  equipment in  Argentina.  The Kenting
         assets are being  operated by  Servicios  and are expected to more than
         double the size of Servicios' operations based on revenues.

         COMPETITION AND OTHER EXTERNAL FACTORS

         Despite a significant  amount of  consolidation  having  occurred,  the
         domestic  well  service rig and  production  service  industry is still
         highly  fragmented  and includes a number of companies that are capable
         of competing effectively in all or part of the Company's well servicing
         markets.  Nonetheless,  the Company  believes that it is competitive in
         terms of  pricing,  performance,  equipment,  safety,  availability  of
         equipment  to meet  customer  needs and  availability  of  experienced,
         skilled personnel in those regions in which it operates.

         In the well  servicing  market,  an  important  competitive  factor  in
         establishing and maintaining long-term customer relationships is having
         an  experienced,  skilled and well trained work force. In recent years,
         many of the Company's larger customers have placed emphasis not only on
         pricing,  but also on safety records and quality  management systems of
         contractors.  The  Company  believes  that  such  factors  will  be  of
         increased   importance   in  the  future.   The  Company  has  directed
         substantial  resources toward employee safety and training programs, as
         well as its employee  review  process.  While the Company's  efforts in
         these  areas  are not  unique,  many  competitors,  particularly  small
         contractors,  have not undertaken  similar training  programs for their
         employees.  Management  believes that the  Company's  safety record and
         reputation for quality  equipment and service are among the best in the
         industry.

    The Company  acquires oil and gas properties from  independent and major oil
    companies and competes with other  independent  and integrated oil companies
    for the  acquisition  of these  properties.  The Company also  competes with
    other local oil and gas  drilling  contractors,  as well as national oil and
    gas drilling  companies.  As with oil field services,  the need for drilling
    oil and gas wells  fluctuates,  in part,  based on the price of,  and demand
    for, oil and natural gas.

    The Company serves over 750 customers in West Texas, East Texas, New Mexico,
    Oklahoma, Michigan, the Appalachian Basin and Argentina with its two largest
    customers providing 13% and 7%, of total Company revenue during fiscal 1997.
    The need for  oilfield  services  fluctuates,  in part,  in  relation to the
    demand for oil and natural gas. As demand for those  commodities  increases,
    service  and  maintenance  requirements  increase  as oil  and  natural  gas
    producers  attempt to maximize the producing  efficiency of their wells in a
    higher priced environment.

    EMPLOYEES

    As of June 30,  1997,  the Company  employed  3,175  persons  (3,047 in well
    service operations,  12 in oil and gas production,  105 in contract drilling
    operations  and 11 in  corporate).  None  of  the  Company's  employees  are
    represented by a labor union or collective bargaining agent. The Company has
    experienced no work stoppages  associated  with labor disputes or grievances
    and considers its relations with its employees to be satisfactory.

    REGULATIONS

    The oilfield service  operations and the oil and gas production and drilling
    activities  of the Company are subject to various  local,  state and federal
    laws and  regulations  intended to protect the  environment.  The  Company's
    operations routinely involve the handling of waste materials,  some of which
    are  classified  as  hazardous  substances.  Consequently,  the  regulations
    applicable  to the  Company's  operations  include  those  with  respect  to
    containment,  disposal and  controlling  the  discharge of any hazardous oil
    field waste and other  non-hazardous  waste  material into the  environment,
    requiring  removal and cleanup  under  certain  circumstances,  or otherwise
    relating  to  the  protection  of  the  environment.  Laws  and  regulations
    protecting the environment  have become more stringent in recent years,  and
    may in certain  circumstances  impose "strict liability,"  rendering a party
    liable for environmental damage without regard to negligence or fault on the
    part of such  party.  Such laws and  regulations  may expose the  Company to
    liability for the conduct of, or conditions  caused by, others,  or for acts
    of the Company  which were in  compliance  with all  applicable  laws at the
    times such acts were performed.  Management of the Company  believes that it
    is in  substantial  compliance  with all material  federal,  state and local
    regulations  as they  relate to the  environment.  Although  the Company has
    incurred certain costs in complying with environmental laws and regulations,
    such amounts have not been  material to the  Company's  financial  condition
    during the three past fiscal years.

    Management  believes that the Company is in substantial  compliance with all
    known material local,  state and federal safety  guidelines and regulations.
    In order to comply with such safety  guidelines and regulations and increase
    employee  awareness of on-the-job  safety,  the Company employs eight safety
    officers.  The Company also has a safety training and education center which
    is used by it for continued safety training and awareness.

    representative of the interest factor.

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

The following discussion provides information to assist in
the  understanding  of  the  Company's   financial   condition  and  results  of
operations.  It should be read in conjunction with the financial  statements and
related notes appearing elsewhere in this report.

     Overview

     The Company  experienced  its most  successful year during fiscal 1997. All
regions  have  increased  equipment  use  because of higher oil and gas  prices,
increased emphasis on horizontal drilling,  lower production costs for major and
independent oil and gas producers,  renewed focus on domestic production and the
effects of several new alliances the Company entered into with its customers.

     Fluctuations in well servicing  activity have had a strong correlation with
fluctuations  in oil  and  gas  prices.  If oil  and  gas  prices  were  to drop
significantly from current levels, the Company would expect a decrease in demand
for drilling and services which would negatively affect the Company's  operating
performance.  The Company seeks to minimize the effects of such  fluctuations on
its  operations and financial  condition  through  diversification  of services,
entry into new markets and customer alliances.

     FISCAL YEAR ENDED JUNE 30, 1997 VERSUS FISCAL YEAR ENDED JUNE 30, 1996

     Results of Operations

     Operating Income

     The Company

     Revenues for the year ended June 30, 1997 increased  $97,152,000,  or 146%,
from $66,478,000 in fiscal 1996 to $163,630,000 in fiscal 1997, while net income
for fiscal 1997 increased  $5,512,000,  or 154% , from $3,586,000 in fiscal 1996
to $9,098,000 in fiscal 1997. The increase was primarily due to oilwell  service
acquisitions  throughout  the year,  increased  oil and gas revenues from Odessa
Exploration, and increased oil and gas drilling revenues.

     Oilfield Services

     Oilfield  service  revenues  for the year  ended  June 30,  1997  increased
$88,452,000,  or 158%,  from  $55,933,000  for the year ended  June 30,  1996 to
$144,385,000  for the year  ended  June 30,  1997.  The  increase  is  primarily
attributable  to  acquisitions  throughout  the year and  higher  equipment  use
resulting from an increase in demand for oilfield services.

     Oil and Natural Gas Exploration and Production

     Revenues from oil and gas  activities  increased  $4,005,000,  or 96%, from
$4,175,000  during the year ended June 30,  1996 to  $8,180,000  for the current
year.  The increase was primarily the result of increased  production of oil and
natural gas from  several  wells that were drilled and began  production  during
fiscal 1997,  higher oil and natural gas prices for fiscal  1997,  and the April
1996 purchase of $6.9 million of oil and gas properties  from an unrelated third
party.  Of the total  $8,180,000  of revenues  for the year ended June 30, 1997,
approximately  $6,975,000  was  from  the  sale of oil  and  gas and  $1,205,000
represented primarily administrative fee income.

     Oil and Natural Gas Well Drilling

     Revenues from oil and gas well drilling activities increased $3,768,000, or
61%, from  $6,188,000  during the year ended June 30, 1996 to $9,956,000 for the
year ended June 30, 1997.  The increase  was  primarily  the result of increased
oilwell drilling activity and an increase in the Company's pricing structure.

     Operating Expenses

     Oilfield Services

     Oilfield  service  expenses  for the year  ended  June 30,  1997  increased
$59,629,000,  or 146%,  from  $40,737,000  for the year ended  June 30,  1996 to
$100,366,000 for the year ended June 30, 1997. The increase was due primarily to
acquisitions  made  throughout  the fiscal year  and the  increased  demand for
oilfield  services.  In  addition,  the  Company  has  continued  to expand  its
services,  offering  fishing tools,  blow-out preventers and oilwell frac
tanks.

     Oil and Natural Gas Exploration and Production

     Expenses related to oil and gas activities increased  $1,680,000,  or 124%,
from  $1,350,000  for the year ended June 30,  1996 to  $3,030,000  for the year
ended June 30, 1997. The increase was primarily the result costs associated with
several oil and natural gas wells that were drilled and began producting  during
fiscal  1997  and  the  April  1996  purchase  of  $6.9  million  in oil and gas
properties.

     Oil and Natural Gas Well Drilling

     Expenses  related  to  oil  and  gas  well  drilling  activities  increased
$3,125,000,  or 62%,  from  $5,030,000  for the  year  ended  June  30,  1996 to
$8,155,000  for the year ended June 30, 1997.  The increase  was  primarily  the
result of increased revenues.

     Depreciation and Depletion Expense

     Depreciation,  depletion and amortization expense increased $6,719,000,  or
143%,  from  $4,701,000  for fiscal 1996 to  $11,420,000  for fiscal  1997.  The
increase is primarily due to oilfield service depreciation expense, which is the
result of increased oilfield service capital expenditures for the current period
versus the prior period and the acquisitions  completed  throughout fiscal 1997.
In addition,  depletion  expense increased for the period due to the increase in
the production of oil and natural gas.

     General and Administrative Expenses

     General and administrative  expenses increased  $11,914,000,  or 180%, from
$6,608,000  for the year ended June 30, 1996 to  $18,522,000  for the year ended
June 30, 1997.  The  increase was  primarily  attributable  to oilfield  service
acquisitions throughout the fiscal year.


     Interest Expense

     Interest expense increased $5,058,000,  or 204%, from $2,477,000 for fiscal
1996 to $7,535,000 in fiscal 1997. The increase was primarily the result of debt
incurred in connection with acquisitions completed throughout fiscal 1997.


                                     - 13 -

     Income Taxes

     Income tax expense increased $3,612,000, or 191%, from $1,888,000 in income
tax expense for fiscal  1996 to  $5,500,000  for fiscal  1997.  The  increase in
income taxes is primarily due to the increase in operating income.  However, the
Company  does not expect to be  required  to remit a  significant  amount of the
$5,500,000  in total  federal  income  taxes for fiscal year 1997 because of the
availability of net operating loss carryforwards,  accelerated  depreciation and
drilling tax credits.

     Cash Flow

     Net cash provided by operating  activities  decreased  $4,965,000,  or 70%,
from  $7,121,000  during fiscal 1996 to $2,156,000 for fiscal 1997. The decrease
is  attributable  primarily to increases  in accounts  receivable,  decreases in
accounts payable and accrued expenses,  but was partially offset by increases in
depreciation and net income.

    Net cash used in investing activities increased $68,511,000,  or 506%, from
$13,551,000 for fiscal 1996 to $82,062,000 for fiscal 1997. The increase   is 
primarily  the result of  increased  capital  expenditures  for oilwell  service
operations and oilwell service acquisitions.

     Net cash provided by financing  activities was $117,399,000 for fiscal 1997
as compared to  $9,366,000  for fiscal  1996,  which  represents  an increase of
$108,033,000,  or 1,153%. The increase, which is partially offset by repayments
of  long-term  debt,  is  primarily  the result of  proceeds  from the  existing
Debentures and commercial paper during the current fiscal year.

     FISCAL YEAR ENDED JUNE 30, 1996 VERSUS FISCAL YEAR ENDED JUNE 30, 1995

     Operating Income

     The Company

     Revenues for the year ended June 30, 1996  increased  $21,789,000,  or 49%,
from  $44,689,000  for the year ended June 30, 1995 to $66,478,000  for the year
ended  June 30,  1996,  while net  income  increased  $1,408,000,  or 65%,  from
$2,178,000 in fiscal 1995 to $3,586,000 in fiscal 1996. The increase in revenues
was primarily due to the acquisition of Clint Hurt Drilling in March 1995, whose
operations  were only  included  for one quarter in the 1995  year-end  results,
increased oil and gas revenues  from Odessa  Exploration  and increased  oilwell
service  equipment use and the  acquisition of WellTech.  The increase in fiscal
year 1996 net income over fiscal year 1995 net income was partially attributable
to the inclusion of Clint Hurt Drilling and the acquisition of WellTech Eastern,
but also was a result of an  increase  in oilwell  service  equipment  use and a
decrease in total  consolidated  Company  costs and expenses as a percentage  of
total revenues.

     Oilfield Services

     Oilfield  service  revenues  for the year  ended  June 30,  1996  increased
$15,828,000,  or 40%,  from  $40,105,000  for the year  ended  June 30,  1995 to
$55,933,000  for the year ended June 30,  1996.  The  increase in  revenues  was
primarily  attributable  to higher  equipment use resulting  from an increase in
demand for oilfield  services and the  acquisition  of WellTech  Eastern,  whose
operating  results  were  included  for the period of March 26, 1996 to June 30,
1996.

     Oil and Natural Gas Exploration and Production

     Revenues from oil and gas  activities  increased  $1,841,000,  or 79%, from
$2,334,000  during the year ended June 30, 1995 to $4,175,000 for the year ended
June 30, 1996.  The increase in revenues was  primarily  the result of increased
production  of oil and natural gas from several  wells that were drilled  during
1996,  higher oil and natural gas prices during 1995 and the April 1996 purchase
of $6.9 million of oil and gas properties from an unrelated third party.

     Of the total  $4,175,000  of  revenues  for the year ended  June 30,  1996,
approximately  $3,554,000  was from  the  sale of oil and gas and the  remaining
$621,000  was  attributable  primarily  to  administrative  fee income and other
miscellaneous income.

     Oil and Natural Gas Well Drilling

     Oil and natural gas well  drilling  operations  are performed by Clint Hurt
Drilling which was acquired in March 1995. Comparable numbers for the prior year
are,  therefore,  not available.  Revenues for the year ended June 30, 1996 were
$6,188,000.

     Operating Expenses

     Oilfield Services

     Oilfield  service  expenses  for the year  ended  June 30,  1996  increased
$10,145,000,  or 33%,  from  $30,592,000  for the year  ended  June 30,  1995 to
$40,737,000  for the year ended June 30, 1996. The increase was due primarily to
the acquisition of WellTech  Eastern on March 26, 1996, and an increased  demand
for oilfield services.

     Oil and Natural Gas Exploration and Production

     Expenses related to oil and gas activities increased $593,000, or 78%, from
$757,000 for the year ended June 30, 1995 to $1,350,000  for the year ended June
30, 1996.  The increase was primarily the result of increased  production of oil
and natural gas from several wells that were drilled  during fiscal 1996 and the
April 1996 purchase of $6.9 million in oil and gas properties.

     Oil and Natural Gas Well Drilling

     Clint Hurt Drilling was acquired in March 1995.  Comparable numbers for the
prior year are, therefore,  not available.  Expenses for the year ended June 30,
1996 were $5,030,000.

     Depreciation and Depletion Expense

     Depreciation,  depletion and amortization expense increased $1,963,000,  or
72%, from $2,738,000 for fiscal 1995 to $4,701,000 for fiscal 1996. The increase
was primarily due to oilfield service depreciation expense,  which resulted from
an increase in oilfield service capital  expenditures for the 1996 period versus
the prior period and the  acquisition  of WellTech and Clint Hurt.  In addition,
depletion expense increased for the period due to the increase in the production
of oil and natural gas.

     General and Administrative Expenses

     General and  administrative  expenses  increased  $2,256,000,  or 52%, from
$4,352,000  for the year ended June 30,  1995 to  $6,608,000  for the year ended
June 30, 1996.  The increase was primarily  attributable  to the  acquisition of
contract drilling assets, the subsequent inclusion of general and administrative
expenses related to contract drilling operations and the acquisition of WellTech
Eastern.

     Interest Expense

     Interest  expense  increased  $999,000,  or 68%, from $1,478,000 for fiscal
1995 to  $2,477,000  for fiscal 1996.  The increase was  primarily the result of
acquisitions  and the  addition  of  certain  oil and gas  properties  that were
financed with proceeds from borrowings.
 
     Income Taxes

     Income tax  expense  for  fiscal  1996  increased  $738,000,  or 64%,  from
$1,150,000  in fiscal  1995 to  $1,888,000  in fiscal  1996.  The  increase  was
primarily due to an increase in operating income.  However,  the Company was not
required to remit a significant amount of the $1,888,000 in total federal income
taxes for fiscal year 1996 because of the  availability  of net  operating  loss
carryforwards, accelerated depreciation and drilling tax credits.

     Cash Flow

     Net cash provided by operating  activities increased  $3,863,000,  or 119%,
from  $3,258,000  during fiscal 1995 to $7,121,000 for fiscal 1996. The increase
was attributable primarily to increases in net income.

     Net cash used in investing  activities increased  $6,397,000,  or 89%, from
$7,154,000  for fiscal 1995 to  $13,551,000  for fiscal  1996.  The increase was
primarily  the  result  of  increased  capital  expenditures  for  oil  and  gas
properties and costs associated with the acquisition of WellTech.  This increase
was partially offset by a decrease in oilfield service capital expenditures.



                                     - 16 -
<PAGE>


     Net cash provided by financing  activities increased  $5,368,000,  or 134%,
from  $3,998,000 in fiscal 1995 to  $9,366,000  in fiscal 1996.  The increase is
primarily the result of increased  principal  payments  during fiscal 1996. This
increase in principal  payments was somewhat  offset by an increase in proceeds
from  long-term debt during fiscal 1996 as the result of the purchase of oil and
gas properties by Odessa Exploration and the acquisition of WellTech.

     LIQUIDITY AND CAPITAL RESOURCES

     The Company's cash and cash equivalents  increased by $37.5 million for the
year ended June 30, 1997 from $4.2 million as of June 30, 1996 to $41.7  million
as of June 30, 1997.  This  increase was  primarily  the result of proceeds from
the Bank Credit Agreement.

     The  Company  has  projected  $20  million  for  oilfield  service  capital
expenditures  for fiscal 1998 as compared to $15.1  million and $5.2  million in
fiscal 1997 and 1996, respectively.  Odessa Exploration has projected outlays of
approximately  $10 million in development  costs for fiscal 1998, as compared to
$8.2 million and $9.8 million in fiscal 1997 and 1996, respectively.  Clint Hurt
Drilling has forecast  approximately $2 million for oil and gas drilling capital
expenditures for fiscal 1998,  primarily for improvements to existing  equipment
and  machinery,  as  compared to $1.5  million  for fiscal 1997 and  $598,000 in
fiscal 1996.  The Company  expects to finance  these  capital  expenditures  and
development  costs using cash flows from  operations and available  credit.  The
Company  believes  that its cash flows and, to the extent  required,  borrowings
under  the Bank Credit Agreement,   will  be  sufficient  to  fund  such
expenditures.

     Debt

     In June 1997,  the Company  entered  into the Credit  Agreement  (the "Bank
Credit Agreement") with PNC Bank, N.A. ("PNC"), as administrative agent, Norwest
Bank Texas,  N.A.,  as  collateral  agent,  Lehman  Commercial  Paper,  Inc., as
advisor,  arranger and syndication  agent and the lenders named therein pursuant
to which the  lenders  agreed to make  available  to the  Compaany  a  five-year
revolving  credit  facilty in the amount of $135 million and a  seven-year  term
loan  facility  in the amount of $120  million.  Up to $10 million of letters of
credit  may be issued  pursuant  to the Bank  Credit  Agreement.  The  amount of
letters of credit  outstanding from time to time reduces the amount of revolving
credit loans which may be outstanding.

     Revolving credit loans incurred  pursuant to the Bank Credit Agreement will
bear interest,  at the Company's  option, at PNC's base rate plus 1.00% or LIBOR
plus 2.25% and term loans will bear interest,  at the Company's option, at PNC's
base rate plus 1.75% or LIBOR plus 2.75%.  After  September 30, 1997, the margin
applicable to revolving  credit loans will  fluctuate  from time to time between
0.25% and 1.25% with respect to base rate loans and between  1.50% and 2.50% for
LIBOR based loans.  Such  fluctuations  will be based on the Company's  ratio of
consolidated  total  debt (net of cash in excess of $5  million)  to a pro forma
calculation  of  consolidated  earnings  before  interest  expense,   taxes  and
depreciation, depletion and amortization.

     The Company used the proceeds from the Bank Credit  Agreement to: (i) repay
existing debt; (ii) make additional  acquisitions and capital expenditures;  and
(iii) provide working capital. Long-term debt that was repaid with proceeds from
the Bank Credit  Agreement in June 1997 included all debt with CIT  Group/Credit
Finance,  Inc. of approximately  $54.3 million and all bank debt associated with
Odessa  Exploration,  previously with Norwest Bank Texas, N.A., of approximately
$2.1 million.

     Impact of SFAS 121

     As of July 1, 1996,  the Company  adopted the  provisions  of  Statement of
Financial Accounting Standards No. 121 - Accounting for Impairment of Long-Lived
Assets and for Long-Lived  Assets to be Disposed Of ("SFAS 121").  Consequently,
the Company reviews its long-lived assets to be held and used, including oil and
gas properties  accounted for under the successful efforts method of accounting,
whenever  events or  circumstances  indicate  that the  carrying  value of those
assets may not be  recoverable.  Long-lived  assets to be  disposed of are to be
accounted  for at the lower of  carrying  amount or fair value less cost to sell
when management has committed to a plan to dispose of the assets. All companies,
including  successful efforts oil and gas companies,  are required to adopt SFAS
121 for fiscal years  beginning  after  December 15, 1995. In order to determine
whether an impairment had occurred,  the Company  estimated the expected  future
cash flows of its income  producing  equipment  and oil and gas  properties  and
compared such future cash flows to the carrying amount of the asset to determine
if the carrying amount was recoverable.  Based on this process,  no writedown in
the carrying amount of the Company's property was necessary at June 30, 1997.

     Impact of Recently Issued Accounting Standards

     The Financial  Accounting Standards Board has recently issued the following
accounting standards which will be adopted by the Company in the future.

     Statement of Financial Accounting Standards No. 128 ("SFAS 128") - Earnings
per Share,  is effective for periods  ending on or after  December 15, 1997. FAS
128 replaces the  presentation  of primary  earnings per share  ("EPS") with the
presentation  of basic EPS, which excludes  dilution and is computed by dividing
income available to common shareholders by the weighted-average number of common
shares  outstanding for the period.  SFAS 128 also requires dual presentation of
basic EPS and diluted  EPS on the face of the income  statement  and  requires a
reconciliation  of the  numerators  and  denominators  of basic EPS and  diluted
EPS.The Company will adopt SFAS 128 for the quarter ended December 31, 1997.

     Statement  of  Financial  Accounting  Standards  No.  130  ("SFAS  130")  -
Reporting  Comprehensive  Income,  is effective for fiscal years beginning after
December 15, 1997.  Reclassification of financial statements for earlier periods
provided for comparative  purposes is required.  The Company will adopt SFAS 130
for the fiscal year ended June 30, 1999.

     Statement  of  Financial  Accounting  Standards  No.  131  ("SFAS  131")  -
Disclosures  about  Segments  of  an  Enterprise  and  Related  Information,  is
effective for financial  statements  for periods  beginning  after  December 15,
1997.  SFAS 131 need not be  applied  to  interim  financial  statements  in the
initial year of its application.  However,  comparative  information for interim
periods in the initial year of  application  is to be reported in the  financial
statements for interim  periods in the second year of  application.  The Company
will adopt SFAS 131 for the fiscal year ended June 30, 1999.

     Management  believes the  adoption of SFAS 128,  SFAS 130 and SFAS 131 will
not have a material effect on its financial position or results of operations of
the Company.

     Impact of Inflation on Operations

     Management  is of the  opinion  that  inflation  has not had a  significant
impact on the Company's business.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                          June 30, 1997, 1996 and 1995

     1. ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES 

The Company

     Key Energy Group,  Inc. herein after referred to as the "Company" or "Key",
was organized in April 1977, and commenced  operations in July 1978.  Results of
operations for the twelve months ended June 30, 1997,  1996 and 1995 include the
Company's oilfield service operations conducted by its wholly-owned  subsidiary,
Yale E. Key, Inc.,  ("Yale E. Key"),  the Company's oil and gas  exploration and
production  wholly-owned  subsidiary,  Odessa Exploration  Incorporated ("Odessa
Exploration"),  and the Company's oil and gas well drilling operations conducted
by the Company's wholly-owned subsidiary,  Key Energy Drilling, Inc. d/b/a Clint
Hurt Drilling ("Clint Hurt Drilling"). Clint Hurt Drilling was acquired in March
of 1995.  Also included in the results of  operations  for the fiscal year ended
June 30, 1997 and approximately  three months for the fiscal year ended June 30,
1996 are those  operating  results from the Company's  wholly-owned  subsidiary;
WellTech  Eastern,  Inc.  ("WellTech  Eastern") which currently holds the assets
acquired in the merger with WellTech, Inc. ("WellTech"),  on March 26, 1996 (see
Note  2).  WellTech  Eastern  operates  through  two  divisions;   the  WellTech
Mid-Continent  Division and the WellTech  Eastern  Division.  In addition,  as a
result of the  Welltech  acquisition,  the Company  acquired a 63%  ownership in
Servicios WellTech, S.A. ("Servicios"),  an Argentinean  corporation.  Servicios
conducts  oilfield  services  operations in Argentina and is accounted for using
the consolidation with a minority interest method.

Basis of Presentation

     The Company's consolidated financial statements include the accounts of the
Company  and  its  wholly-owned  subsidiaries.   All  significant  inter-company
transactions  and  balances  have  been  eliminated.   The  accounting  policies
presented  below have been followed in preparing the  accompanying  consolidated
financial  statements.  The Company's  ownership of less than 50% owned entities
are  accounted  for by the cost or equity  methods,  depending on the  Company's
ownership percentage.

Estimates and Uncertainties

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

Inventories

     Inventories, which consist primarily of oilwell service parts and supplies,
are held for use in the operations of Key and are valued at the lower of average
cost or market.

Property and Equipment

     The Company  provides for  depreciation and amortization of non-oil and gas
properties using the  straight-line  method over the following  estimated useful
lives of the assets:

                          (table follows on next page)

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - (continued)


     Description                                                     Years
     ---------------------------------------------------------------------
                  Oilfield service equipment                        3 - 20
                  Oil and gas well drilling equipment               3 - 15
                  Motor vehicles                                    3 - 7
                  Furniture and equipment                           3 - 10
                  Buildings and improvements                       10 - 40
                  Gas processing facilities                           10
     ---------------------------------------------------------------------

     Upon  disposition  or  retirement of property and  equipment,  the cost and
related  accumulated  depreciation are removed from the accounts and the gain or
loss thereon, if any, is included in the results of operations.

     Odessa Exploration utilizes the successful efforts method of accounting for
its oil and gas  properties.  Under  this  method,  all  costs  associated  with
productive wells and  nonproductive  development  wells are  capitalized,  while
nonproductive  exploration  costs and geological and geophysical costs (if any),
are expensed. Capitalized costs relating to proved properties are depleted using
the  unit-of-production  method.  Upon  disposition,  the  carrying  amounts  of
properties sold or otherwise disposed of and the related allowance for depletion
are  eliminated  from the accounts  and any  gain/loss is included in results of
operations.

Gas Balancing

     Deferred  income  associated  with gas  balancing is  accounted  for on the
entitlements  method  and  represents  amounts  received  for gas sold under gas
balancing  arrangements in excess of Odessa Exploration's interest in properties
covered by such agreements.  Odessa  Exploration had deferred income  associated
with gas balancing of approximately  $155,000,  $198,000 and $253,000 as of June
30, 1997, 1996 and 1995, respectively.

Environmental

     The Company is subject to extensive federal,  state and local environmental
laws and regulations.  These laws, which are constantly  changing,  regulate the
discharge  of  materials  into the  environment  and may  require the Company to
remove or  mitigate  the  environmental  effects of the  disposal  or release of
petroleum or chemical  substances at various sites.  Environmental  expenditures
are  expensed  or  capitalized  depending  on  their  future  economic  benefit.
Expenditures that relate to an existing  condition caused by past operations and
that have no future economic benefits are expensed. Liabilities for expenditures
of a  noncapital  nature  are  recorded  when  environmental  assessment  and/or
remediation is probable, and the costs can be reasonably estimated.

Other Assets and Goodwill

     At June 30,  1997,  1996 and 1995,  other  assets  consisted  primarily  of
goodwill,  capitalized debt issuance costs and security and escrow deposits from
Key's workers' compensation  retrospective  insurance program, in addition to an
interest, (approximately 13%), in an insurance company (the insurance company is
affiliated with Key's workers' compensation carrier).

                     Key Energy Group, Inc. and Subsidiaries

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - (continued)

     At June 30, 1997,  1996 and 1995,  the Company  classified  as goodwill the
cost in excess of fair value of the net  tangible  assets  acquired  in purchase
transactions.  Goodwill is being amortized on a straight-line  basis over ten to
twenty-five   years.   Management   continually   evaluates  whether  events  or
circumstances  have occurred that indicate the remaining useful life of goodwill
may  warrant  revision  or  the  remaining   balance  of  goodwill  may  not  be
recoverable.  Goodwill amortization expense totaled $622,000 for fiscal 1997 and
$100,000  for fiscal 1996 and  $100,000  for fiscal  1995.  Debt  issuance  cost
amortization  expense  totaled  $344,000 for the year ended June 30, 1997 and is
amortized over the term of the applicable debt.

Earnings per Share

     Primary  earnings per common share are  determined by dividing net earnings
applicable  to common  stock by the  weighted  average  number of common  shares
actually outstanding during the year and common equivalent shares resulting from
the assumed  exercise of stock  options and warrants (if any) using the treasury
stock method,  except in periods with reported losses as the inclusion of common
stock equivalents would be antidilutive. Fully diluted earnings per common share
are based on the increased  number of shares that would be outstanding  assuming
conversion  of  dilutive  outstanding  convertible  securities  using the "as if
converted" method.

Income Taxes

     The Company  accounts  for income  taxes based upon  Statement of Financial
Accounting  Standards No. 109, "Accounting for Income Taxes" ("SFAS 109"). Under
SFAS 109,  deferred tax assets and liabilities are recognized for the future tax
consequences   attributable  to  differences  between  the  financial  statement
carrying  amounts of existing assets and  liabilities  and their  respective tax
bases.  Deferred tax assets and liabilities are measured using enacted tax rates
expected  to apply to  taxable  income  in the  years in which  those  temporary
differences are expected to be recovered or settled.  The effect on deferred tax
assets and  liabilities  of a change in tax rate is  recognized in income in the
period that includes the enactment date. A valuation  allowance for deferred tax
assets is  recognized  when it is "more  likely  than not" that the  benefit  of
deferred tax assets will not be realized.

     The Company and its eligible subsidiaries file a consolidated U. S. federal
income tax return.  Certain  subsidiaries  that are  consolidated  for financial
reporting  purposes  are not eligible to be included in the  consolidated  U. S.
federal  income tax return and  separate  provisions  for income taxes have been
determined for these entities or groups of entities.

Concentration of Credit Risk

     Financial   instruments,   which   potentially   subject   the  Company  to
concentrations  of credit risk,  consist primarily of temporary cash investments
and trade  receivables.  The Company  restricts  investment  of  temporary  cash
investments to financial  institutions  with high credit  standing and by policy
limits the  amount of credit  exposure  to any one  financial  institution.  The
Company's customer base consists  primarily of multi-national,  foreign national
and  independent  oil and  natural  gas  producers.  See Note 12 for  additional
information   regarding   customers   which  accounted  for  more  than  10%  of
consolidated  revenues.  The Company performs ongoing credit  evaluations of its
customers and generally  does not require  collateral on its trade  receivables.
Such  credit risk is  considered  by  management  to be limited due to the large
number  of  customers  comprising  the  Company's  customer  base.  The  Company
maintains reserves for potential credit losses, and such losses have been within
management's expectations.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - (continued)

Impact of  SFAS 121

     On July 1, 1996,  the  Company  adopted  the  provisions  of  Statement  of
Financial Accounting Standards No. 121 - Accounting for Impairment of Long-Lived
Assets and for Long-Lived  Assets to be Disposed Of ("SFAS 121"). This Statement
requires that long-lived assets and certain identifiable intangibles be reviewed
for impairment  whenever  events or changes in  circumstances  indicate that the
carrying amount of an asset may not be  recoverable.  Adoption of this Statement
did  not  have  an  impact  on the  Company's  financial  position,  results  of
operations, or liquidity.

Stock-based Compensation

     The  Company  accounts  for  employee  stock-based  compensation  using the
intrinsic value method prescribed by Accounting Principles Board Opinion No. 25,
Accounting for Stock Issued to Employees  ("APB 25").  Accordingly,  the company
has only adopted the disclosure  provisions of Statement of Financial Accounting
Standards No. 123,  Accounting for Stock-Based  Compensation  ("SFAS 123").  See
Note 8 for the pro forma  disclosures of compensation  expense  determined under
the fair-value provisions of SFAS 123.

Cash Flows

     For cash flow  purposes,  the Company  considers  all  unrestricted  highly
liquid  investments with less than a three month maturity when purchased as cash
equivalents.

Reclassifications

     Certain  reclassifications  have  been  made to the  fiscal  1996  and 1995
consolidated financial statements to conform to the fiscal 1997 presentation.

Impact of Recently Issued Accounting Standards

     The Financial  Accounting Standards Board has recently issued the following
accounting standards which will be adopted by the Company in the future.

     Statement of Financial Accounting Standards No. 128 ("SFAS 128") - Earnings
per Share,  is effective for periods  ending on or after  December 15, 1997. FAS
128 replaces the  presentation  of primary  earnings per share  ("EPS") with the
presentation  of basic EPS, which excludes  dilution and is computed by dividing
income available to common shareholders by the weighted-average number of common
shares  outstanding for the period.  SFAS 128 also requires dual presentation of
basic EPS and diluted  EPS on the face of the income  statement  and  requires a
reconciliation  of the  numerators  and  denominators  of basic EPS and  diluted
EPS.The Company will adopt SFAS 128 for the quarter ended December 31, 1997.

     Statement  of  Financial  Accounting  Standards  No.  130  ("SFAS  130")  -
Reporting  Comprehensive  Income,  is effective for fiscal years beginning after
December 15, 1997.  Reclassification of financial statements for earlier periods
provided for comparative  purposes is required.  The Company will adopt SFAS 130
for the fiscal year ended June 30, 1999.

     Statement  of  Financial  Accounting  Standards  No.  131  ("SFAS  131")  -
Disclosures  about  Segments  of  an  Enterprise  and  Related  Information,  is
effective for financial  statements  for periods  beginning  after  December 15,
1997.  SFAS 131 need not be  applied  to  interim  financial  statements  in the
initial year of its application.  However,  comparative  information for interim
periods in the initial year of  application  is to be reported in the  financial
statements for interim  periods in the second year of  application.  The Company
will adopt SFAS 131 for the fiscal year ended June 30, 1999.

                     Key Energy Group, Inc. and Subsidiaries

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - (continued)

Management  believes the  adoption of SFAS 128,  SFAS 130 and SFAS 131 will
not have a material effect on its financial position or results of operations of
the Company.

its business.

4.  COMMITMENTS AND CONTINGENCIES

     Various  suits and claims  arising in the  ordinary  course of business are
pending against the Company. Management does not believe that the disposition of
any of these items will result in a material  adverse impact to the consolidated
financial position of the Company. As of June 30, 1997, the Company had reserved
$133,000 for potential suits and claims.

     During 1995, the Company entered into employment agreements with certain of
its officers.  These employment  agreements  generally run to June 30, 1997, but
will  automatically  be  extended on a yearly  basis  unless  terminated  by the
Company or the  applicable  officer.  In addition to providing a base salary for
each officer, the employment  agreements provide for severance payments for each
officer  varying from 12 to 24 months of the officers  base salary.  The current
annual base salaries for the officers  covered under such employment  agreements
total approximately $800,000.

5.  LONG-TERM DEBT

     On June 6, 1997,  the Company  entered into an agreement  (the "Bank Credit
Agreement") with PNC Bank, N.A., as  administrative  agent,  Norwest Bank Texas,
N.A., as collateral agent.  Lehman Commercial Paper, Inc., as advisor,  arranger
and  syndication  agent and the  lenders  named  thereas  pursuant  to which the
lenders  provided a $255 million credit  facility,  consisting of a $120 million
seven-year term loan and a $135 million five-year  revolver.  The interest rate,
on the term  loan,  is LIBOR  plus 2.75  percent  and the  interest  rate on the
revolver  varies based on the LIBOR and the level of the Company's  indebtedness
and is currently LIBOR plus 2.25 percent. The Company used the proceeds from the
facility to: (i) repay existing bank debt; (ii) make additional acquisitions and
capital expenditures; and (iii) provide working capital. In addition, the credit
facility provides, under certain conditions,  for the repurchase of a portion of
the Company's  outstanding common stock in the open market from time to time. In
connection  with the credit  facility,  the  company  incurred  and  capitalized
$4,979,000 of debt issuance costs. These costs are being amortized over the life
of the  credit  facility.  The  credit  facility  contains  certain  restrictive
covenants and requires certain financial ratios.

     Long-term  debt which was repaid with  proceeds  from the Agreement in June
1997  included  all  debt  with  CIT  Group/Credit   Finance,  Inc.  ("CIT")  of
approximately   $54.3  million  and  all  bank  debt   associated   with  Odessa
Exploration,   previously   with  Norwest  Bank  Texas,   N.A.   ("Norwest")  of
approximately $2.1 million.

     In July  1996,  the  Company  completed  the  offering  of  $52,000,000  7%
convertible subordinated debentures due 2003 (the "Debentures"). In August 1996,
the interest  rate on the  Debentures  was increased to 7 1/2%. As the result of
the Company's purchase of the remaining 37% ownership in Servicios, the interest
rate was  reduced to 7% in July of 1997.  The  offering  was a private  offering
pursuant  to Rule  144A  under the  Securities  Act of 1933.  Proceeds  from the
offering were used to substantially repay existing long-term debt (approximately
$35.2 million).  In connection with the offering of the Debentures,  the Company
capitalized  and incurred  $2,410,000  of debt issuance  costs.  These costs are
being amortized over the life of the Debentures.  The Debenture contains certain
restrictive covenants and requires certain financial ratios.

     The Debentures mature on July 1, 2003 and are convertible at any time after
November 1, 1996 and before maturity, unless previously redeemed, into shares of
the Company's common stock at a conversion price of $9 3/4 per share, subject to
adjustment in certain events. In addition, holders of the Debentures who convert
prior to July 1, 1999 will receive, in addition to the Company's common stock, a
payment  generally  equal  to 50%  of  the  interest  otherwise  payable  on the
converted  Debentures from the date of conversion  through July 1, 1999, payable
in cash or common stock, at the Company's option.  Interest on the Debentures is
payable  semi-annually on January 1 and July 1 of each year,  commencing January
1, 1997. In August,  1996, the interest rate was increased from 7% to 7 1/2% due
to  certain  modifications  in  the  Debenture  indenture  involving  a  certain
subsidiary's  
                                     - 32 -

inability  to  guarantee  the  obligations  under  the  indenture,
relating to the Debentures (the "Prospectus"), (specifically, Servicios). As the
result of the  Company's  purchase of the  remaining 37% ownership in Servicios,
the interest rate was reduced to 7% in July of 1997.

     The Debentures  will not be redeemable by the Company before July 15, 1999.
Thereafter,  the  Debentures  will be redeemable at the option of the Company in
whole or part,  at the  declining  redemption  prices set forth in the  original
Prospectus,  together with accrued and unpaid interest thereon.(see Note 17, for
further discussion.)

     In January 1996, prior to the consummation of the Bank Credit Agreement and
offering  described  above,  the Company,  Yale E. Key,  Clint Hurt and WellTech
entered into separate  credit  facilities  with CIT totaling  approximately  $35
million (the combined maximum credit limit). The credit facilities were combined
into one facility after the consummation of the Welltech merger.  As a result of
the separate  credit  facilities,  the interest rate for Yale E. Key was lowered
from two and one-half to one and one-quarter  percent over the stated prime rate
(8.25% at June 30,  1996).  Each of the CIT term notes  required  principal  and
interest  payments,  due the first day of each month beginning February 1, 1996,
plus a final  payment of the unpaid  balance of the note due  December 31, 1998.
The expiration of each of the lines of credit was December 31, 1998.

     The components of long-term debt are as follows:

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

     (i).  Under  the  Bank  Credit  Agreement,  the term  loan of $120  million
     requires interest payments at the termination of the LIBOR interest period.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - (continued)

     (ii). The Debentures mature on July 1, 2003 and are convertible at any time
     after November 1, 1996 and before  maturity,  unless  previously  redeemed,
     into shares of the Company's  common stock at a conversion  price of $9 3/4
     per share, subject to adjustment in certain events. In addition, holders of
     the Debentures who convert prior to July 1, 1999 will receive,  in addition
     to the Company's  common  stock,  a payment  generally  equal to 50% of the
     interest  otherwise  payable on the converted  Debentures  from the date of
     conversion  through July 1, 1999,  payable in cash or common stock,  at the
     Company's  option.  Interest on the Debentures is payable  semi-annually on
     January 1 and July 1 of each year,  commencing  January 1, 1997. In August,
     1996,  the  interest  rate was  increased  from 7% to 7 1/2% due to certain
     modifications in the Debenture indenture  involving a certain  subsidiary's
     inability to guarantee the obligations under the indenture, relating to the
     Debentures (the "Prospectus"),  (specifically, Servicios). As the result of
     the Company's  purchase of the  remaining  37% ownership in Servicios,  the
     interest rate was reduced to 7% in July of 1997.

     (iii).  The CIT term note,  as  amended,  required  principal  payments  of
     approximately $275,000, plus interest, due the first day of each month plus
     a final  payment of the unpaid  balance of the note due  December 31, 1998.
     The interest  rate was one and  one-quarter  percent above the stated prime
     rate of 8.25% at June 30, 1996. The note was  collateralized  by all of the
     assets  (including  equipment and inventory) of Yale E. Key, Clint Hurt and
     WellTech  Eastern.  The CIT line of credit,  as amended,  required  monthly
     payments of interest at one and one-quarter  percent above the stated prime
     rate of 8.25% at June 30, 1996.  The line of credit was  collateralized  by
     the accounts  receivable of Yale E. Key,  Clint Hurt and WellTech  Eastern.
     The agreement with CIT included  certain  restrictive  covenants,  the most
     restrictive of which prohibited the Company from making  distributions  and
     declaring dividends on its common stock.

      (iv).  Prior  to  the  Agreement  and  Offering  described  above,  Odessa
      Exploration  had a loan  agreement,  as amended,  with  Norwest.  The loan
      agreement  provided  for a $7.5  million  revolving  line of  credit  note
      subject to a borrowing base limitation (approximately $6.3 million at June
      30, 1996).  The borrowing base was  redetermined on at least a semi-annual
      basis. The borrowing base was reduced by approximately  $100,000 per month
      through  October 1997; the maturity of the note. The note's  interest rate
      was one-half of one percent over Norwest's prime rate of 8.25% at June 30,
      1996.  The  note  was  secured  by  substantially  all of the oil and gas
      properties of Odessa Exploration.

      The  loan  agreement  had  contained  various  restrictive  covenants  and
      compliance  requirements,  which included (a) prohibits Odessa Exploration
      from declaring or paying dividends on Odessa  Exploration's  common stock,
      (b)  limiting  the  incurrence  of  additional   indebtedness   by  Odessa
      Exploration,  (c) the  limitation  on the  disposition  of assets  and (d)
      various financial covenants.

      (v).  In  April,  1996,  as the  result  of  the  acquisition  of  certain
      properties  by Odessa  Exploration,  but prior to the  Offering  described
      above, Odessa Exploration entered into a loan agreement with Norwest.  The
      loan  agreement  provided for a term loan of $9.3 million to be reduced by
      $2.4 million in principal amount after the consummation of the acquisition
      of certain properties by Odessa Exploration.  The note's interest rate was
      one-half of one  percent  over  Norwest's  prime rate of 8.25% at June 30,
      1996. The note required interest payments beginning June 1, 1996. The note
      was secured by  substantially  all of the oil and gas properties of Odessa
      Exploration.

      Presented  below is a schedule of the repayment  requirements of long-term
      debt for each of the next five years and thereafter as of June 30, 1997:

6.  FAIR VALUE OF FINANCIAL INSTRUMENTS

     The  carrying  amount of cash and cash  equivalents,  accounts  receivable,
accounts  payable and accrued  expenses,  other current assets and other current
liabilities  approximates  fair  value  because of the short  maturity  of these
instruments.

     Based on the  borrowing  rates  currently  estimated to be available to the
Company  for  loans  with  similar  terms,  the  fair  value of  long-term  debt
approximates  the carrying  amount as of June 30, 1997 and 1996,  except for the
subordinated  convertible  debentures which have a carrying value of $52 million
and a fair value of approximately $98.9 million at June 30, 1997.

   Other accrued liabilities consist of the following:

8. STOCKHOLDERS' EQUITY

The 1995 Stock Option Plan

     On March 26,  1996,  a Stock  Option Plan (the "1995 Plan") was approved by
the Company's stockholders. The Plan became effective July 1, 1995, and , unless
terminated  earlier,  will terminate July 1, 2005. The 1995 Plan is administered
by a committee (the "Committee")  consisting of at least three directors of Key,
each of whom is a "disinterested  person" within the meaning of rule 16b-3 under
the Exchange Act and an "outside  director" within the meaning of Section 162(m)
of the Code.

<PAGE>
                     Key Energy Group, Inc. and Subsidiaries

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - (continued

      The total number of shares of the Company's common stock that may be
subject to options under the 1995 Plan may not exceed 1,800,000 in the
aggregate.  The total amount of common stock with respect to which options
may be granted over the life of the 1995 Plan to any single employee shall
not exceed 500,000  shares in the  aggregate.  Options which are canceled,
forfeited or have expired or expire by their terms without being exercised
shall be available  for future  grants under the 1995 Plan.  The Committee
may  determine  which key  employees of the Company or any  subsidiary  or
other persons shall be granted  options under the 1995 Plan,  the terms of
the  options  and the number of shares  which may be  purchased  under the
option.

     The individuals  eligible to receive options under the 1995 Plan consist of
key employees  (including  officers who may be members of the Board),  directors
who are neither employees nor members of the Committee and other individuals who
render  services  of  special   importance  to  the  management,   operation  or
development  of  Key or any  subsidiary,  and  who  have  contributed  or may be
expected  to  contribute  materially  to the  success  of  Key or a  subsidiary,
provided, however, that only key employees are eligible to receive options.

     The price at which shares of common stock may be purchased upon exercise of
an option will be specified by the  Committee at the time the option is granted,
but in the case of an individual stock option,  except under certain conditions,
may not be less than the fair  market  value of the common  stock on the date of
grant.  The  duration  of any  option  is  determined  by the  Committee  in its
discretion and shall be specified in the option  agreement.  No individual stock
option may be exercisable after the expiration of ten years.

The 1995 Outside Directors Stock Option Plan

     On March 26, 1996, an Outside  Directors  Stock Option Plan was approved by
the Company's Shareholder's (the "Directors Plan"). Individuals who are "Outside
Directors"  are  eligible to  participate  in the  Directors  Plan.  An "Outside
Director"  is  defined  as a  member  of the  Board of  Directors  who is not an
employee of the Company or any of its  subsidiaries.  Under the Directors  Plan,
Outside Directors are divided into three groups dependent upon certain dates and
length of service on the Board. Only nonqualified stock options ("NSO's") may be
granted under the Directors  Plan. An NSO granted under the Directors Plan shall
expire ten years  after the date of the grant.  An NSO may not be granted  under
the Directors Plan after July 1, 1998.

     The  Directors  Plan  provides  for the issuance of an aggregate of 400,000
shares of common stock,  which may be authorized but unissued  shares,  treasury
shares,  or shares  purchased on the open market.  The exercise price of the NSO
shall be the fair market value on the date of the grant.

     The following  table  summarizes the stock option  activity  related to the
Company's plans:

                                                                       Price

     The Company  applies APB 25 and related  Interpretations  in accounting for
its  stock  option  awards.   Accordingly,  no  compensation  expense  has  been
recognized for its stock option awards.  If  compensation  expense for the stock
option awards had been  determined  consistent  with SFAS 123, the Company's net
income  and net income per  share,  for the years  ended June 30,  1997 and 1996
would have been adjusted to the following pro forma  amounts:  

      (unaudited)                                       Year Ended June 30, 
                                                           1997      1996

      Net income (in thousands)                           $8,680    $2,945
      Primary net income per share                        $ 0.71    $ 0.37
      Fully-diluted net income per share                  $ 0.61    $ 0.35
         
     The pro forma net income and pro forma net income per share  amounts  noted
above  are not  likely  to be  representative  of the pro  forma  amounts  to be
reported in future  years.  Pro forma  adjustments  in future years will include
compensation expense associated with the options granted in fiscal year 1996 and
1997 plus  compensation  expense  associated  with any options awarded in future
years. As a result,  such pro forma compensation  expense is likely to be higher
than the levels reflected for 1996 and 1997 if any options are awarded in future
years.

     Under SFAS 123,  the fair value of each stock  option grant is estimated on
the  date of  grant  using  the  Black-Scholes  option  pricing  model  with the
following weighted average assumptions used for grant in 1997 and 1996:

                                                       1997              1996

           Risk-free interest rate                     6.59%             6.54%
           Expected life                               5 years           5 years
           Expected volatility                         28%               29%
           Expected dividend yield                       0%                0%

The total fair value of options granted at June 30, 1997 is $6,541,000.

     A valuation allowance is provided when it is more likely than not that some
portion of the deferred tax assets will not be realized.  Based on  expectations
for the future,  management  has  determined  that taxable income of the Company
will more likely than not be sufficient to fully utilize available carryforwards
prior to their ultimate expiration.

     The Company  estimates  that as of June 30,  1997,  the  Company  will have
available approximately  $148,414,060 of net operating loss carryforwards (which
begin to expire in 2001). The net operating loss carryforwards are subject to an
annual limitation of approximately  $940,000,  under Sections 382 and 383 of the
Internal Revenue Code.

10.  LEASING ARRANGEMENTS

     Among other leases, the Company (primarily its subsidiaries), lease certain
automotive  equipment  under  non-cancelable  operating  leases which expire at
various dates through 2002. The term of the operating  leases generally run from
36 to 60 months with varying  payment dates  throughout each month. In addition,
in the case of Yale E. Key,  each  lease  includes  an option  to  purchase  the
equipment and an excess mileage charge as defined in the leases.

     As  of  June  30,  1997,   the  future   minimum   lease   payments   under
non-cancelable operating leases, in thousands, are as follows:

                                                    =========

     Operating  lease  expense was  approximately  $5,299,000,  $2,897,000,  and
$1,930,000,   for  the  fiscal  years  ended  June  30,  1997,  1996  and  1995,
respectively.

11.  EMPLOYEE BENEFIT PLANS

     At June 30,  1997,  as the  result of the  WellTech  merger  (Note 2),  the
Company  maintains two 401-(k) plans (the "Plans") for its employees.  Employees
of WellTech  Eastern are eligible for  participation  in one Plan (the "WellTech
401-(k) Plan"),  while all other employees are eligible for participation in the
other Plan (the "Key 401-(k) Plan").  The Company intends to merge the two Plans
at January 1, 1998. The 401-(k) plans cover  substantially  all employees of the
Company.  The  Company  matches  employees'  contributions  up  to  10%  of  the
employees'  contribution to the Key 401-(k) Plan.  These  contributions  totaled
approximately  $35,000,  $19,000 and $20,000 for the years ended June 30,  1997,
1996 and 1995, respectively.  Additionally, the Company contributed $300,000 and
$37,000 into the WellTech  401-(k) Plan for the year ended June 30, 1997 and the
period of March 26,  1996 (the date of the  WellTech  merger) to June 30,  1996,
respectively . The Company agreed to match employee  contributions up to 50% (to
a  maximum  of $1,000  per  employee)  of the  employees'  contributions  to the
WellTech 401-(k) Plan.

12.  MAJOR CUSTOMERS

     Sales to customers  representing  10% or more of consolidated  revenues for
the years ended June 30, 1997, 1996 and 1995 were as follows:

                                                 Fiscal Year Ended June 30,

13.  TRANSACTIONS WITH RELATED PARTIES

     WellTech  Eastern paid $78,000 and $18,000 for the year ended June 30, 1997
and for the period March 26, 1996 (the date of the Welltech  merger) to June 30,
1996,  respectively,  for office/yard  rental expense in which an officer of the
Company and  WellTech  Eastern has an  interest.  In the opinion of the Board of
Directors of the Company,  based on the Board's review of competitive bids, this
transaction was on terms at least as favorable to the Company as could have been
obtained from a third party.

     In connection  with the Odessa  Exploration  acquisition,  (see Note 2) the
Company granted D. Kirk Edwards  (President of Odessa  Exploration) a percentage
reversionary  working interest in five deep gas wells located in West Texas upon
repayment  of  $1,622,000  of  the  bank  debt  assumed  by the  Company  in the
acquisition  from the  Company's  earnings from the five wells.  The  percentage
reversionary  working  interest  decreases based on the date of repayment of the
assumed  bank debt and ranges  from 20% of the  earnings  from the five wells if
repayment  occurs on or prior to July 7, 1995,  to 5% of the  earnings  from the
five wells if repayment occurs after July 7, 1996.

     Key leases  automotive  equipment from an independent third party (see Note
10). The  independent  third party  purchases the  automotive  equipment from an
automobile  dealership in which a former officer owns a majority  interest.  Net
proceeds to the automobile  dealership  totaled $399,000 for the year ended June
30, 1995.  The leases are  considered  operating  leases.  In the opinion of the
Board of Directors of the Company,  the net proceeds from  automotive  equipment
were on terms at least as favorable  to the Company as could have been  obtained
from a third  party.  This opinion is based on  information  provided by a third
party leasing  company,  that is not  affiliated  with the former officer or the
Company, to the Board of Directors regarding purchase prices and equipment lease
rentals offered by third parties.

14.  CONCENTRATIONS OF CREDIT RISK

     The Company has a  concentration  of customers in the oil and gas industry.
Substantially all of the Company's customers are major integrated oil companies,
major independent  producers of oil and gas and smaller  independent  producers.
This may affect the Company's  overall exposure to credit risk either positively
or negatively,  in as much as its customers are effected by economic  conditions
in the oil and gas industry,  which has  historically  been  cyclical.  However,
accounts  receivable are well diversified among many customers and a significant
portion  of the  receivables  are from  major oil  companies,  which  management
believes minimizes potential credit risk. Historically,  credit losses have been
insignificant.  Receivables  are  generally  not  collateralized,  although  the
Company may generally secure a receivable at any time by filing a mechanic's and
material-mans' lien on the well serviced.

15.  BUSINESS SEGMENT INFORMATION

     Key operates a variety of oilfield  service  equipment  including  workover
rigs, hot oil units,  transports and various other oilfield servicing equipment.
In addition, Key performs a variety of other oilfield services including fishing
tools, frac tanks and blow-out preventers.

     Oil  and  gas  production  is  conducted  by  Odessa  Exploration.   Odessa
Exploration  acquires and manages  interests in producing oil and gas properties
for its own account  and for its  sponsored  investors.  Odessa  Exploration  is
engaged in the  drilling  and  production  of oil and  natural gas in the United
States.  Odessa Exploration acquires producing oil and gas properties from major
and independent  producers.  After  acquisition,  Odessa  Exploration may either
rework  the  acquired  wells  to  increase   production   and/or  form  drilling
partnerships for additional development wells.

     Oil and gas well drilling  services are  conducted by Clint Hurt  Drilling.
Clint Hurt  Drilling  operates six drilling  rigs which drill for oil and gas in
the West Texas area.

16.  DERIVATIVE FINANCIAL INSTRUMENTS

     The  Company   utilizes   derivative   financial   instruments   to  manage
well-defined  commodity price risks.  The Company is exposed to credit losses in
the event of nonperformance by the  counterparties to its commodity hedges.  The
Company  anticipates,  however,  that such  counterparties will be able to fully
satisfy  their  obligations  under the  contracts.  The Company  does not obtain
collateral or other security to support financial  instruments subject to credit
risk but monitors the credit standing of the counterparties.

     The Company  utilizes option contracts to hedge the effect of price changes
on future  oil and gas  production.  If market  prices of oil and gas exceed the
strike price of put  options,  the options  will expire  unexercised,  therefore
reducing the effective  price  received for oil and gas sales by the cost of the
related option.  As of June 30, 1996,  Odessa  Exploration had 6,000 Bbls of oil
per month hedged with a strike price of $19.50 per Bbl., from the period of July
1, 1996 through December 31, 1996.

     Premiums paid for commodity  options contracts are amortized to oil and gas
sales over the terms of the agreements.  Unamortized  premiums of $91,789 and $0
are included in other current assets in the  consolidated  balance sheet at June
30, 1996 and 1997,  respectively.  Amounts  receivable,  if any, under commodity
option  contracts  are  accrued  as an  increase  in oil and gas  sales  for the
applicable periods.

Oil and Gas Reserve Information

     Estimates  of Odessa  Exploration's  proved oil and gas reserves as of June
30,  1997,  1996 and 1995  were  prepared  by the  Company  and  reviewed  by an
independent  petroleum  reservoir  engineering  firm.  Estimates  were  made  in
accordance   with   guidelines   established  by  the  Securities  and  Exchange
Commission.  Proved oil and gas reserves are the  estimated  quantities of crude
oil and natural gas which  geological  and  engineering  data  demonstrate  with
reasonable  certainty to be  recoverable  in future years from known  reservoirs
under existing  economic  conditions,  i.e.  prices and costs as of the date the
estimate is made.  Prices utilized reflect  consideration of changes in existing
prices  provided by  contractual  arrangements,  if any, but not of  escalations
based upon future conditions.  The reserve estimates are presented  utilizing an
average oil price of $21.00 Bbl and an average natural gas price of $2.20 Mcf as
of June 30, 1997.

     Proved  developed oil and gas reserves are reserves that can be expected to
be recovered through existing equipment and operating methods.

     Proved  undeveloped  oil and gas  reserves  are  proved  reserves  that are
expected to be recovered  from new wells on undrilled  acreage or from  existing
wells where a  relatively  major  expenditure  is required for  recompletion  or
secondary  or tertiary  recovery.  Reserves  assigned to  undrilled  acreage are
limited to those drilling units that offset productive units reasonably  certain
of production when drilled.

     No major  discovery or other  favorable or adverse event has occurred since
July 1,  1997  which is  believed  to have  caused a  significant  change in the
estimated proved oil and gas reserves of Odessa Exploration.

     Odessa  Exploration's  estimate  of  reserves  has not been  filed  with or
included in reports to any federal agency other than the Securities and Exchange
Commission.

     Oil  and  gas   reserve   quantity   estimates   are  subject  to  numerous
uncertainties inherent in the estimation of quantities of proved reserves and in
the  projection  of future  rates of  production  and the timing of  development
expenditures.  The  accuracy of such  estimates  is a function of the quality of
available data and of engineering  and geological  interpretation  and judgment.
Results of subsequent  drilling,  testing and production may cause either upward
or downward revision of previous estimates.  Further,  the volumes considered to
be  commercially  recoverable  fluctuate  with  changes in prices and  operating
costs. The Company  emphasizes that reserve  estimates are inherently  imprecise
and that estimates of new discoveries are more imprecise than those of currently
producing oil and gas properties.  Accordingly,  these estimates are expected to
change as additional information becomes available in the future.

Standardized Measure of Discounted Future Cash Flows

     The following  schedules present  estimates of the standardized  measure of
discounted  future net cash flows from the Company's  proved reserves as of June
30,  1996,  and an analysis of the changes in these  amounts for the years ended
June 30, 1996 and 1995. June 30, 1997 information is not included, as during the
current  year  oil  and  gas  producing  activities  are  no  longer  considered
significant in accordance with reporting  requirements  under FAS 14 - Financial
Reporting for Segments of a Business Enterprise. Estimated future cash flows are
determined  using  year-end  prices  adjusted  only for fixed  and  determinable
increases for natural gas provided by contractual  agreement (if any). Estimated
future  production  and  development  costs are based on economic  conditions at
year-end.  Future  federal  income taxes are computed by applying the  statutory
federal income tax rate of 34% to the  difference  between the future pretax net
cash flows and the tax basis of proved oil and gas properties, after considering
investment  tax  credits  and  net  operating  loss   carry-forwards  (if  any),
associated with these properties.

     Discounted  future  cash flow  estimates  like  those  shown  below are not
intended to  represent  estimates  of the fair value of oil and gas  properties.
Estimates  of fair value should also  consider  probable  reserves,  anticipated
future oil and gas prices, interest rates, changes in development and production
costs and risks  associated with future  production.  Because of these and other
considerations,  any  estimate  of fair  value  is  necessarily  subjective  and
imprecise.

                          Independent Auditors' Report



To The Board of Directors 
  and Stockholders Key Energy Group, Inc.

     We have audited the accompanying  consolidated balance sheets of Key Energy
Group,  Inc.  and  Subsidiaries  as of June 30,  1997 and 1996,  and the related
consolidated  statements of operations,  stockholders' equity and cash flows for
each  of the  years  in the  three-year  period  ended  June  30,  1997.  These
consolidated  financial  statements  are  the  responsibility  of the  Company's
management.  Our  responsibility is to express an opinion on these  consolidated
financial statements based on our audits.

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

     In our opinion,  the consolidated  financial  statements  referred to above
present fairly, in all material respects, the consolidated financial position of
Key Energy Group,  Inc. and  Subsidiaries  as of June 30, 1997 and 1996, and the
results  of their  operations  and their cash flows for each of the years in the
three-year  period ended June 30, 1997, in conformity  with  generally  accepted
accounting principles.

reasonably  be  expected  to have a  material  adverse  effect on the use of the
Assets  by  Buyer.   Neither  Seller  nor  the  Shareholders  has  received  any

Business,  as a result  of the  consummation  of the  transactions  contemplated
hereby.

of all  employees  of Seller  that are  involved  in the  ownership,  operation,
maintenance  or use of the Assets or the  conduct of the  Workover  Rig  Service
Business  (the  "Employees").  Seller does not  currently  sponsor,  maintain or
contribute  to, and has not at anytime  sponsored,  maintained or contributed to
any  employee  benefit  plan which is or was  subject to any  provisions  of the
Employee Retirement Income Security Act of 1974, as amended. No employee benefit
plan of Seller will, by its terms or applicable  law,  become binding upon or an
obligation of Buyer.  Buyer has not engaged in any unfair labor  practices which
could  reasonably  be  expected  to result in a material  adverse  effect on the
Assets  or the  Business.  Seller  does  not have  any  dispute  with any of its
existing or former employees. There are no labor disputes or to the knowledge of
Seller, any disputes threatened by current or former employees of Seller.

governmental   entity  with  respect  to  Seller  or  any  of  the  transactions
contemplated  by this  Agreement or the Seller  Agreements is pending or, to the

indicated to Seller an intention to conduct the same. There is no suit,  action,
or legal,  administrative,  arbitration,  or other  proceeding  or  governmental
investigation  pending to which Seller is a party or, to the knowledge of Seller
or Shareholders,  to which might become a party, and which particularly  affects
the Assets or property being transferred to Seller.

Shareholders nor any officer,  employee or agent of Seller, nor any other person

supplier,  government employee or other person who is or may be in a position to
help or hinder the  profitable  use of the Assets or conduct of the Business (or
to assist Seller in connection with any actual or proposed transaction) which if
not  given  in the  past,  might  have  had a  material  adverse  effect  on the
profitable use of the Assets or conduct of the Business , or if not continued in
the future,  might materially  adversely effect the profitable use of the Assets
or conduct of the Business.


     2.1.12. Solvency.  Seller is not now insolvent, nor will Seller be rendered
insolvent by the occurrence of the transactions  contemplated by this Agreement.
The term  "insolvent"  means that the sum of the present fair and saleable value
of  Seller's  assets  does not and will not exceed its debts and other  probable
liabilities,  and the term "debts" includes any legal liability  whether matured
or unmatured, liquidated or unliquidated, absolute fixed or contingent, disputed
or undisputed or secured or unsecured.

complete and correct  copies of  customers,  and if  required,  Seller will make
available records relating principally to the Assets and the business,  and such
information   covers  all   commitments   and  liabilities  of  Seller  relating
principally to the Assets.  This Agreement,  the Seller Agreements and the other
instruments  executed  by  Seller  or  Shareholders  and  delivered  to Buyer in
connection  herewith do not include any untrue  statement of a material  fact or
omit to state any material fact necessary to make the statements made herein and
therein not misleading in any material respect.

transactions   contemplated   hereby  have  been  carried  on  by  Seller,   the
Shareholders and their counsel directly with Buyer and its counsel,  without the
intervention  of any other  person  in such  manner as to give rise to any valid
claim against any of the parties hereto for a brokerage commission, finder's fee
or any similar payment.

                                 Indemnification

     5.1  Indemnification  by Seller and the  Shareholders.  In  addition to any
other remedies available to Buyer under this Agreement,  or at law or in equity,
each of Seller and Shareholders shall, jointly and severally,  indemnify, defend
and hold harmless  Buyer,  and its respective  officers,  directors,  employees,

of  action  and  deficiencies,  including  interest,  penalties  and  reasonable
attorneys' fees and expenses (collectively,  the "Damages") that such indemnitee
shall incur or suffer,  which arise, result from or relate to (I) any breach of,
or  failure   by  Seller  or   Shareholders   to   perform,   their   respective
representations, warranties, covenants or agreements in this Agreement or in any
schedule,  certificate,  exhibit or other  instrument  furnished or delivered to
Buyer by Seller or the  Shareholders  under this Agreement and (ii) the Retained
Liabilities.

to Seller or Shareholders  under this Agreement,  or at law or in equity,  Buyer
shall,  jointly  and  severally,   indemnify,   defend  and  hold  harmless  the

<PAGE>

     5.3 Indemnification  Procedure.  If any party hereto discovers or otherwise
becomes aware of an  indemnification  claim arising under Section 5.1 or Section
5.2 of this Agreement,  such indemnified  party shall give written notice to the
indemnifying  party,  specifying  such claim,  and may  thereafter  exercise any
remedies available to such party under this Agreement  provided,  however,  that
the failure of any indemnified party to give notice as provided herein shall not
relieve the indemnifying party of any obligations  hereunder,  to the extent the
indemnifying party is not materially prejudiced thereby. Further, promptly after
receipt by an indemnified  party hereunder of written notice of the commencement
of any action or  proceeding  with respect to which a claim for  indemnification
may be made pursuant to this Article 5, such indemnified party shall, if a claim
in respect thereof is to be made against any  indemnifying  party,  give written
notice to the latter of the commencement of such action provided,  however, that
the failure of any indemnified party to give notice as provided herein shall not
relieve the indemnifying party of any obligations  hereunder,  to the extent the
indemnifying party is not materially prejudiced thereby. In case any such action
is  brought  against an  indemnified  party,  the  indemnifying  party  shall be
entitled to participate in and to assume the defense  thereof,  jointly with any
other  indemnifying  party similarly  notified,  to the extent that it may wish,
with counsel  reasonably  satisfactory to such indemnified party, and after such
notice from the indemnifying  party to such indemnified party of its election so
to assume the defense  thereof,  the  indemnifying  party shall not be liable to
such indemnified party for any legal or other expenses  subsequently incurred by
the latter in connection with the defense thereof unless the indemnifying  party
has failed to assume the defense of such claim and to employ counsel  reasonably
satisfactory to such indemnified person. An indemnifying party who elects not to
assume the defense of a claim  shall not be liable for the fees and  expenses of
more than one counsel in any single  jurisdiction for all parties indemnified by
such  indemnifying  party with  respect to such claim or with  respect to claims
separate but similar or related in the same jurisdiction arising out of the same
general allegations.  Notwithstanding any of the foregoing to the contrary,  the
indemnified  party will be  entitled  to select its own  counsel  and assume the
defense of any action  brought  against it if the  indemnifying  party  fails to
select counsel reasonably satisfactory to the indemnified party, the expenses of
such defense to be paid by the indemnifying  party. No indemnifying  party shall
consent to entry of any judgment or enter into any settlement  with respect to a
claim without the consent of the indemnified  party,  which consent shall not be

validly  existing and in good standing under the laws of the State of Texas, has
full requisite  corporate  power and authority to carry on its business as it is
currently  conducted,  and to own and operate the properties currently owned and
operated by it, and is duly  qualified or licensed to do business and is in good
standing as a foreign corporation authorized to do business in all jurisdictions
in which the  character  of the  properties  owned or the nature of the business
conducted by it would make such  qualification  or licensing  necessary,  except

adverse effect on its financial condition, properties or business.

     2.1.2.  Agreement  Authorized and its Effect on Other Obligations.  Each of
the  Shareholders  is above the age of 18 years,  and has the legal capacity and
requisite power and authority to enter into, and perform his  obligations  under
this Agreement.  This Agreement is a valid and binding obligation of each of the
Shareholders  enforceable  against each of the  Shareholders  (subject to normal
equitable principles) in accordance with its terms, except as enforceability may
be limited by bankruptcy, insolvency,  reorganization,  debtor relief or similar
laws affecting the rights of creditors generally. The execution, delivery and


                                        2
<PAGE>

     performance of this Agreement by the Shareholders will not conflict with or
result in a violation  or breach of any term or provision  of, nor  constitute a
default under (a) the Articles of  Incorporation or Bylaws of Phoenix or (b) any
obligation,  indenture,  mortgage,  deed of  trust,  lease,  contract  or  other
agreement  to which  Phoenix or any of the  Shareholders  is a party or by which
Phoenix or either of the Shareholders or their respective properties are bound.

     2.1.3. Capitalization. The authorized capitalization of Phoenix consists of
25,000 shares of Phoenix  Common  Stock,  of which,  as of the date hereof,  300
shares are issued and  outstanding  and held  beneficially  and of record by the
Shareholders. On the date hereof, Phoenix does not have any outstanding options,
warrants,  calls  or  commitments  of  any  character  relating  to  any  of its
authorized  but unissued  shares of capital  stock.  All issued and  outstanding
shares  of  Phoenix  Common  Stock  are  validly  issued,  fully  paid  and non-
assessable  and are not subject to preemptive  rights.  None of the  outstanding
shares of Phoenix Common Stock is subject to any voting trusts, voting agreement
or other agreement or understanding  with respect to the voting thereof,  nor is
any proxy in existence with respect thereto.

transfer  and  assign  to  Key  the  Phoenix  Shares,  free  and  clear  of  all
Encumbrances.  Upon transfer to Key by the  Shareholders  of the Phoenix Shares,
Key will own the Phoenix Shares free and clear of all Encumbrances. There are no
claims  pending or, to the  knowledge  of any of the  Shareholders,  threatened,
against  Phoenix or either of the  Shareholders  that concern or affect title to
either the Phoenix Shares,  or that seek to compel the issuance of capital stock
or other securities of Phoenix.

     2.1.5.  No  Subsidiaries.  There  is  no  corporation,  partnership,  joint
venture,  business trust or other legal entity in which Phoenix, either directly
or indirectly  through one or more  intermediaries,  owns or holds beneficial or
record ownership of at least a majority of the outstanding voting securities.

     2.1.6. Financial Statements.  The Shareholders have delivered to Key copies
of Phoenix's unaudited balance sheet and related statements of income,  retained
earnings  and cash flows as at and for the 12 months  ended  December  31,  1996
(collectively  the  "12/31  Financial   Statements")  and  copies  of  Phoenix's
unaudited  balance sheet (the "4/30 Balance Sheet"),  and related  statements of
income,  retained  earnings and cash flows  (collectively,  the "4/30  Financial
Statements"),  for the four  months  ended April 30,  1997 (the  "Balance  Sheet

basis.  The accounts  receivable  reflected in the 4/30 Balance Sheet,  or which
have been thereafter acquired by Phoenix, have been collected or are collectible

Sheet,  or which have  thereafter  been  acquired  by it,  consist of items of a

hereto. The Phoenix  Intellectual  Property is owned or licensed by Phoenix free
and clear of any  Encumbrance.  Phoenix has not granted to any other  person any

Intellectual Property or otherwise in connection with Phoenix's operation of its
business.

     2.1.13.  Title to and Condition of Assets.  Phoenix has good,  indefeasible
and marketable title to all its properties,  interests in properties and assets,

detract  from the value,  or  interfere  with the present  use, of the  property
subject thereto or affected thereby, or otherwise materially impair the business
operations of Phoenix.  All leases  pursuant to which Phoenix leases (whether as
lessee or lessor) any  substantial  amount of real or personal  property  are in
good standing,  valid,  and effective;  and there is not, under any such leases,
any existing  default or event of default or event which with notice or lapse of
time,  or both,  would  constitute  a default by Phoenix and in respect to which
Phoenix has not taken  adequate steps to prevent a default from  occurring.  The
buildings  and  premises of Phoenix  that are used in its  business  are in good
operating  condition  and repair,  subject only to ordinary  wear and tear.  All
rigs, rig equipment, machinery,  transportation equipment, tools and other major
items of equipment of Phoenix are in good operating  condition and in a state of
reasonable maintenance and repair, ordinary wear and tear excepted, and are free
from any known defects except as may be repaired by routine maintenance and such
minor defects as to not  substantially  interfere with the continued use thereof
in  the  conduct  of  normal  operations.  To the  best  of  each  Shareholder's
knowledge,  all such assets conform to all applicable  laws governing their use.

relating  to any such  assets  has been  received  by  Phoenix  or either of the
Shareholders, except such as have been fully complied with.

obligations  of Phoenix.  Phoenix is not, and to the  knowledge of either of the
Shareholders,  no  other  party  to any  such  contract,  lease,  plan or  other
arrangement is, in default thereunder,  and no event has occurred which (with or
without  notice,  lapse of time,  or the  happening  of any other  event)  would
constitute  a default  thereunder.  No contract  has been  entered into on terms
which could reasonably be expected to have an adverse effect on Phoenix. Neither
of  the  Shareholder  has  received  any  information  which  would  cause  such
Shareholder to conclude that any customer of Phoenix


                                        8

in which the  character  of the  properties  owned or the nature of the business

adverse effect on its financial condition, properties or business.

limited by bankruptcy, insolvency, reorganization, debtor relief or similar laws
affecting  the  rights of  creditors  generally.  The  execution,  delivery  and
performance  of this  Agreement  by Key will not  conflict  with or  result in a

indenture,  mortgage, deed of trust, lease, contract or other agreement to which
Key or any of its property is bound.

     2.2.3. Consents and Approvals. No consent, approval or authorization of, or

his  employment.  Each of the  Shareholders  agrees that if either the length of
time  or  geographical  area  set  forth  in  this  Section  3.1 is  deemed  too
restrictive in any court  proceeding,  the court may reduce such restrictions to
those  which  it deems  reasonable  under  the  circumstances.  The  obligations
expressed in this Section 3.1 are in addition to any other  obligations that the
Shareholders may have under any

sells his stock in a corporation  (including a disposition in a merger) to limit
his  activities so that the goodwill and business  relations of his employer and
of the corporation whose stock he has sold (and any successor  corporation) will
not  be  materially  impaired.  Each  of the  Shareholders  further  agrees  and
acknowledges  that Key and its affiliates do not have any adequate remedy at law

agree that Key or Any  affiliate  of Key may, in addition to the other  remedies
which may be  available  to it  hereunder,  file a suit in equity to enjoin such

     indemnitees  shall incur or suffer,  which arise,  result from or relate to
any  breach  of,  or  failure  by Key to  perform,  any of its  representations,
warranties,  covenants  or  agreements  in this  Agreement  or in any  schedule,
certificate,  exhibit or other  instrument  furnished or delivered to Phoenix or
either of the Shareholders by or on behalf of Key under this Agreement.

     4.3. Indemnification  Procedure. If any party hereto discovers or otherwise
becomes aware of an indemnification claim arising under Sections 4.1 4.2, 4.4 or
4.5 of this Agreement,  such indemnified  party shall give written notice to the
indemnifying  party,  specifying  such claim,  and may  thereafter  exercise any
remedies available to such party under this Agreement;  provided,  however, that
the failure of any indemnified party to give notice as provided herein shall not
relieve the indemnifying party of any obligations  hereunder,  to the extent the
indemnifying party is not materially prejudiced thereby. Further, promptly after
receipt by an indemnified  party hereunder of written notice of the commencement
of any action or  proceeding  with respect to which a claim for  indemnification
may be made pursuant to this Article 4, such indemnified party shall, if a claim
in respect thereof is to be made against any  indemnifying  party,  give written
notice to the latter of the commencement of such action; provided, however, that
the failure of any indemnified party to give notice as provided herein shall not
relieve the indemnifying party of any obligations  hereunder,  to the extent the
indemnifying party is not materially prejudiced thereby. In case any such action
is  brought  against an  indemnified  party,  the  indemnifying  party  shall be
entitled to participate in and to assume the defense  thereof,  jointly with any
other  indemnifying  party similarly  notified,  to the extent that it may wish,
with counsel  reasonably  satisfactory to such indemnified party, and after such
notice from the indemnifying  party to such indemnified party of its election so
to assume the defense  thereof,  the  indemnifying  party shall not be liable to
such indemnified party for any legal or other expenses  subsequently incurred by
the latter in connection with the defense thereof unless the indemnifying  party
has failed to assume the defense of such claim and to employ counsel  reasonably
satisfactory to such indemnified person. An indemnifying party who elects not to
assume the defense of a claim  shall not be liable for the fees and  expenses of
more than one counsel in any single  jurisdiction for all parties indemnified by
such  indemnifying  party with  respect to such claim or with  respect to claims
separate but similar or related in the same jurisdiction arising out of the same
general allegations.  Notwithstanding any of the foregoing to the contrary,  the
indemnified  party will be  entitled  to select its own  counsel  and assume the
defense of any action  brought  against it if the  indemnifying  party  fails to
select counsel reasonably satisfactory to the indemnified party, the expenses of
such defense to be paid by the indemnifying  party. No indemnifying  party shall
consent to entry of any judgment or enter into any settlement  with respect to a
claim without the consent of the indemnified  party,  which consent shall not be
unreasonably  withheld,  or unless such  judgment or  settlement  includes as an
unconditional  term  thereof  the giving by the  claimant or  plaintiff  to such
indemnified party of a release from all liability with respect to such claim. No
indemnified  party  shall  consent  to entry of any  judgment  or enter into any
settlement  of any such  action,  the  defense  of which has been  assumed by an
indemnifying  party,  without  the  consent of such  indemnifying  party,  which
consent shall not be unreasonably withheld or delayed.

     4.4. Litigation  Indemnification by Shareholders.  In addition to any other
remedies available to Key under this Agreement,  or at law or in equity, each of
the Shareholders shall


                                       15
<PAGE>

     indemnify,  defend and hold harmless  Phoenix and Key and their  respective
officers,  directors,  employees,  agents  and  stockholders,  against  and with
respect to any Damages that such indemnitees shall incur or suffer, which arise,
result from or relate to or arise out of any  matters  arising out of or related
to the  Shareholder's  or Phoenix's  relationship  to or dealings with Southwest
Petroservices, Inc.

     4.5.  Indemnification  of  Turn  and  Butts  by  Key  for  Certain  Phoenix
Obligations.  In addition to other remedies  available to the Shareholders under
this Agreement,  or at law or in equity,  Key shall  indemnify,  defend and hold
harmless the  Shareholders  against and with  respect to any personal  liability
they may incur as a result of  having  guaranteed  the  obligations  of  Phoenix
listed on Schedule 4.5 hereto.

     This Stock Purchase Agreement (this "Agreement") is entered into as of July

and Monty D. Elmore (the "Shareholder").

                                   WITNESSETH:

     Whereas,  Buyer is a corporation  duly organized and validly existing under
the laws of the State of Delaware,  with its principal  executive offices at Two
Tower Center, Tenth Floor, East Brunswick, New Jersey 08816; and

     Whereas,  Patrick Well Service,  Inc. (the "Company") is a corporation duly
organized and validly  existing under the laws of the State of Kansas,  with its

     Whereas,  the Shareholder  owns 82 shares (the "Company  Shares") of common
stock,  par value $10 per share,  of the Company (the "Company  Common  Stock"),
which  constitutes all of the issued and outstanding  shares of capital stock of
the Company; and

     Whereas,  the  Shareholder  desires to sell to Buyer,  and Buyer desires to
purchase from the Shareholder all of the issued and outstanding capital stock of
the Company.

     Now,  Therefore,  in  consideration  of the  premises  and  of  the  mutual
covenants and agreements  herein  contained,  the parties hereto hereby agree as
follows:

                                    ARTICLE 1

                                Purchase and Sale

     1.1.  Purchase  and Sale of the  Company  Shares.  Subject to the terms and
conditions of this Agreement,  on the date hereof, the Shareholder agree to sell
and convey to Buyer,  free and clear of all  Encumbrances (as defined in Section
2.1.8.1  hereof),  and Buyer agrees to purchase and accept from the Shareholder,

     1.2. Delivery of the Company Certificates. The Shareholder shall deliver to
Buyer on the date hereof duly and validly issued certificate(s) representing all

sixty (60) days after the date hereof . Buyer and the Shareholder  shall jointly
review the Final Balance Sheet and such  supplemental  report,  endeavor in good
faith to resolve all  disagreements  regarding  the entries  thereon and reach a
final determination  thereof within 90 days from the date hereof. Within 10 days
of reaching such final determination,  the following adjusting payments shall be
made:

     (1) If the sum of (A)  Final  Net  Current  Value of the  Company  (defined
below) plus (B) (the "Capital  Expenditure  Allowance"),  which is the amount of

Payment").

     (2) If the sum of (A) the Final Net Current  Value of the Company  plus (B)

the Company, the Shareholder shall pay to Buyer the amount of such difference.

     The term "Final Net Current Value of the Company" means the dollar value of
the amount by which (i) the "Total Current Assets" plus the "Total Other Assets"

recorded on the Final  Balance  Sheet.  The term "3/31 Net Current  Value of the
Company"  means the dollar  value of the amount by which (i) the "Total  Current
Assets" plus the "Total Other  Assets" as recorded on the 3/31 Balance Sheet (as

exhibit or other  instrument  furnished or delivered to Buyer by the Shareholder

Shareholder  of his  representations  and warranties in this Agreement or in any
schedule,  certificate,  exhibit or other  instrument  furnished or delivered to
Buyer by the  Shareholder  under this Agreement for which Buyer fails to provide
written  notice of a claim for such Damages to the  Shareholder on or before the
expiration  of the survival  period (as  specified in Section 5.1 hereof) of the
specific representation or warranty alleged to have been breached.

     4.2.  Indemnification  by and Remedies  Against  Buyer.  In addition to any
other remedies available to the Shareholder under this Agreement or at law or in
equity,  Buyer shall  indemnify  and hold  harmless the  Shareholder,  his wife,
children, agents, representatives,  attorneys,  successors, heirs, executors and
administrators  (collectively  the "Shareholder  Indemnified  Parties") from any
Damages that the Shareholder  Indemnified  Parties shall incur or suffer,  which
arise, result from or relate to (i) any breach of or failure by Buyer to perform
any  of  its  representations,  warranties,  covenants  or  agreements  in  this
Agreement or in any schedule, certificate, exhibit or other instrument furnished
or delivered to the Shareholder by or on behalf of Buyer under this Agreement or
(ii)  the  conduct  of the  Company's  business  on or after  the  date  hereof,
provided,  however, that Buyer shall not be required to so indemnify, defend and
hold  harmless the  Shareholder  Indemnified  Parties as a result of a breach by
Buyer of any of its  representations  and warranties in this Agreement or in any
schedule, certificate, exhibit or other instrument furnished or delivered to the
Shareholder  by Buyer under this  Agreement for which the  Shareholder  fails to
provide  written  notice of the claim for such damages to Buyer on or before the
expiration  of the survival  period (as  specified in Section 5.1 hereof) of the
specific representation or warranty alleged to have been breached.

     4.2.  Indemnification  Procedure.  In  the  event  that  any  party  hereto
discovers or otherwise becomes aware of an  indemnification  claim arising under
Section 4.1 or 4.2 of this Agreement,  such indemnified party shall give written
notice to the  indemnifying  party,  specifying  such claim,  and may thereafter
exercise any remedies  available to such party under this  Agreement;  provided,
however,  that the failure of any  indemnified  party to give notice as provided
herein shall not relieve the indemnifying party of any obligations hereunder, to
the extent the indemnifying party is not materially prejudiced thereby. Further,
promptly  after receipt by an indemnified  party  hereunder of written notice of
the  commencement  of any action or proceeding with respect to which a claim for
indemnification  may be  made  pursuant  to  Section  4.1 or  4.2  hereof,  such
indemnified party shall, if a claim in respect thereof is to be made against any
indemnifying  party,  give written notice to the latter of the  commencement  of
such action;  provided,  however,  that the failure of any indemnified  party to
give notice as provided herein shall not relieve the  indemnifying  party of any
obligations  hereunder,  to the extent the indemnifying  party is not materially
prejudiced  thereby.  In case any such action is brought  against an indemnified
party, the indemnifying  party shall be entitled to participate in and to assume
the  defense  thereof,  jointly  with any  other  indemnifying  party  similarly
notified,  to the extent that it may wish, with counsel reasonably  satisfactory
to such indemnified  party, and after such notice from the indemnifying party to
such  indemnified  party of its election so to assume the defense  thereof,  the
indemnifying  party shall not be liable to such indemnified  party for any legal
or other  expenses  subsequently  incurred by the latter in connection  with the
defense thereof unless the  indemnifying  party has failed to assume the defense
of such claim and to employ counsel reasonably  satisfactory to such indemnified
person.  An  indemnifying  party who elects not to assume the defense of a claim
shall not be liable for the fees and  expenses  of more than one  counsel in any
single  jurisdiction for all parties indemnified by such indemnifying party with
respect to such claim or with respect to claims  separate but similar or related
in  the  same  jurisdiction   arising  out  of  the  same  general  allegations.
Notwithstanding any of the foregoing to the contrary, the indemnified party will
be  entitled  to select its own  counsel  and  assume the  defense of any action
brought against it if the indemnifying  party fails to select counsel reasonably
satisfactory to the indemnified  party,  the expenses of such defense to be paid
by the indemnifying  party. No indemnifying  party shall consent to entry of any
judgment  or enter  into any  settlement  with  respect to a claim  without  the
consent  of the  indemnified  party,  which  consent  shall not be  unreasonably
withheld,  or unless such  judgment or settlement  includes as an  unconditional
term thereof the giving by the claimant or plaintiff to such  indemnified  party
of a release from all liability with respect to such claim. No indemnified party
shall consent to entry of any judgment or enter into any  settlement of any such
action, the defense of which has been assumed by an indemnifying party,  without
the consent of such indemnifying  party, which consent shall not be unreasonably
withheld or delayed.

Noncompetition.Noncompetition.  Except as otherwise  consented to or approved in
writing by Buyer, the Shareholder agrees that for a period of 42 months from the
date hereof,  it will not (and will cause its  affiliates  not to),  directly or
indirectly,  acting  alone or as a member  of a  partnership  or as an  officer,
director,  employee,  consultant,  representative,  holder of, or investor in as
much as 5% of any  security of any class of any  corporation  or other  business
entity (i) engage in any  businesses  involved in  providing  well  servicing or
shallow/moderate  depth drilling services within the country of Argentina;  (ii)

or corporation any trade, technical or technological secrets of the Company, the

organization or business affairs or (iv) induce or actively attempt to influence
any employee of the Company,  the Company Subsidiary,  Buyer or any affiliate of
Buyer to terminate his  employment.  The  Shareholder  agrees that if either the
length of time or geographical  area set forth in this Section 3.1 is deemed too
restrictive in any court  proceeding,  the court may reduce such restrictions to
those  which  it deems  reasonable  under  the  circumstances.  The  obligations
expressed in this Section 3.1 are in addition to any other  obligations that the
Shareholder  may have  under  the  laws of any  jurisdiction  in  which  they do
business  requiring  an employee of a business  or a  shareholder  who sells his
stock in a  corporation  (including  a  disposition  in a  merger)  to limit his
activities  so that the goodwill  and business  relations of his employer and of
the corporation whose stock he has sold (and any successor corporation) will not
be materially impaired.  Each of the Shareholder further agrees and acknowledges
that the Company,  the Company Subsidiary,  Buyer and its affiliates do not have
any  adequate  remedy  at  law  for  the  breach  or  threatened  breach  by the
Shareholder  of  this  covenant,   and  agree  that  the  Company,  the  Company
Subsidiary,  Buyer or any  affiliate  of Buyer  may,  in  addition  to the other
remedies which may be available to it hereunder, file a suit in equity to enjoin
the Shareholder from such breach or threatened breach. If any provisions of this
Section  3.1 are held to be invalid  or against  public  policy,  the  remaining
provisions shall not be affected thereby. The Shareholder  acknowledges that the
covenants set forth in this Section 3.1 are being executed and delivered by such
Shareholder  in  consideration  of the  covenants  of  Buyer  contained  in this
Agreement,  and for other good and valuable  consideration,  receipt of which is
hereby acknowledged.

     3.2.  Employee Matters.  From the date hereof,  the Company and the Company
Subsidiary   shall  remain   responsible  for  all  costs  associated  with  the
termination  of any  of  their  employees  terminated  after  the  date  hereof;
provided,  however, that the Shareholder shall be solely responsible for any and
all  liabilities,  costs and expenses  associated  with the  termination of Gary
Meier by either the Company or the Company Subsidiary,  regardless of whether he
is terminated before, on or after the date hereof (the AMeier Termination@).

     3.3.  Further  Assurances.  From time to time, as and when requested by any
party hereto,  any other party hereto shall execute and deliver,  or cause to be
executed and delivered,  such documents and instruments and shall take, or cause
to be taken,  such further or other  actions as may be  reasonably  necessary to
effectuate the transactions contemplated hereby. Without limiting the generality
of the foregoing,  the Shareholder shall take those actions reasonably requested
by Buyer to (i)  properly  record the  transfer  of the  Company  Shares and the
Shareholder-Owned  Subsidiary  Shares in accordance  with Section 1.2 hereof and
(ii) resolve the title exceptions described in Schedule 2.1.9 hereto.

     Indemnification  ndemnification 4.1. Indemnification by the Shareholder4.1.
Indemnification by the Shareholder.  In addition to any other remedies available
to Buyer under this Agreement,  or at law or in equity,  the  Shareholder  shall
indemnify,  defend and hold harmless the Company, the Company Subsidiary,  Buyer
and their affiliates and their respective officers, directors, employees, agents
and stockholders  (collectively,  the ABuyer Indemnified Parties@),  against and
with  respect  to  any  and  all  claims,  costs,  damages,   losses,  expenses,
obligations,  liabilities, recoveries, suits, causes of action and deficiencies,
including  interest,  penalties and  reasonable  fees and expenses of attorneys,
consultants and experts (collectively, the ADamages@) that the Buyer Indemnified
Parties  shall incur or suffer,  which  arise,  result from or relate to (i) any
breach by the  Shareholder of (or the failure of the Shareholder to perform) its
respective  representations,   warranties,   covenants  or  agreements  in  this
Agreement or in any schedule, certificate, exhibit or other instrument furnished
or delivered to Buyer by the Shareholder  under this Agreement or (ii) the Meier
Termination.

     4.2. Indemnification by Buyer4.2.  Indemnification by Buyer. In addition to
any other remedies available to the Shareholder under this Agreement,  or at law
or in equity,  Buyer shall  indemnify,  defend and hold harmless the Shareholder
against and with  respect to any and all  Damages  that such  indemnitees  shall
incur or suffer, which arise, result from or relate to any breach of, or failure
by  Buyer to  perform,  any of its  representations,  warranties,  covenants  or
agreements in this Agreement or in any schedule,  certificate,  exhibit or other
instrument  furnished or delivered to the  Shareholder  by or on behalf of Buyer
under this Agreement.

     4.3.  Indemnification  Procedure.  In  the  event  that  any  party  hereto
discovers or otherwise becomes aware of an  indemnification  claim arising under
Section 4.1 or 4.2 of this Agreement,  such indemnified party shall give written
notice to the  indemnifying  party,  specifying  such claim,  and may thereafter
exercise any remedies  available to such party under this  Agreement;  provided,
however,  that the failure of any  indemnified  party to give notice as provided
herein shall not relieve the indemnifying party of any obligations hereunder, to
the extent the indemnifying party is not materially prejudiced thereby. Further,
promptly  after receipt by an indemnified  party  hereunder of written notice of
the  commencement  of any action or proceeding with respect to which a claim for
indemnification  may be  made  pursuant  to  Section  4.1 or  4.2  hereof,  such
indemnified party shall, if a claim in respect thereof is to be made against any
indemnifying  party,  give written notice to the latter of the  commencement  of
such action;  provided,  however,  that the failure of any indemnified  party to
give notice as provided herein shall not relieve the  indemnifying  party of any
obligations  hereunder,  to the extent the indemnifying  party is not materially
prejudiced  thereby.  In case any such action is brought  against an indemnified
party, the indemnifying  party shall be entitled to participate in and to assume
the  defense  thereof,  jointly  with any  other  indemnifying  party  similarly
notified,  to the extent that it may wish, with counsel reasonably  satisfactory
to such indemnified  party, and after such notice from the indemnifying party to
such  indemnified  party of its election so to assume the defense  thereof,  the
indemnifying  party shall not be liable to such indemnified  party for any legal
or other  expenses  subsequently  incurred by the latter in connection  with the
defense thereof unless the  indemnifying  party has failed to assume the defense
of such claim and to employ counsel reasonably  satisfactory to such indemnified
person.  An  indemnifying  party who elects not to assume the defense of a claim
shall not be liable for the fees and  expenses  of more than one  counsel in any
single  jurisdiction for all parties indemnified by such indemnifying party with
respect to such claim or with respect to claims  separate but similar or related
in  the  same  jurisdiction   arising  out  of  the  same  general  allegations.
Notwithstanding any of the foregoing to the contrary, the indemnified party will
be  entitled  to select its own  counsel  and  assume the  defense of any action
brought against it if the indemnifying  party fails to select counsel reasonably
satisfactory to the indemnified  party,  the expenses of such defense to be paid
by the indemnifying  party. No indemnifying  party shall consent to entry of any
judgment  or enter  into any  settlement  with  respect to a claim  without  the
consent  of the  indemnified  party,  which  consent  shall not be  unreasonably
withheld,  or unless such  judgment or settlement  includes as an  unconditional
term thereof the giving by the claimant or plaintiff to such  indemnified  party
of a release from all liability with respect to such claim. No indemnified party
shall consent to entry of any judgment or enter into any  settlement of any such
action, the defense of which has been assumed by an indemnifying party,  without
the consent of such indemnifying  party, which consent shall not be unreasonably
withheld or delayed.

     1. The  Argentina  real  property  records do not  currently  show that the
Company  Subsidiary is the owner of the parcel of real  property  located in Las
Heres,  Argentina  and the two  parcels of real  property  located  in  Comodoro
Rivadavia,  Argentina (the ACompany  Property@) that valid purchase documents in

represents  and  warrants  that (i) the Company  Subsidiary  is the owner in fee
simple of the Company Property (with no material Encumbrances thereon),  (ii) no
other party has claimed or can validly claim title to any portion of the Company
Property  and  (iii)  it has (or  will  cause  to be)  delivered  all  documents
necessary to file in the appropriate  real property  records to reflect that the
Company  Subsidiary  owns the  Company  Property  in fee  simple,  free from any
material Encumbrances.

     2.  Some of the  certificates  of  title  covering  the  thirty-seven  (37)
automobiles  and  light  pickup  trucks  owned by the  Company  Subsidiary  (the
ACompany Vehicles@) either do not properly reflect the Company Subsidiary as the
owner thereof or indicate that such  automobile is subject to a third part lien.
The Shareholder represents and warrants that Company Vehicles are owned outright
by the Company  Subsidiary  subject to no Encumbrances,  (ii) no other party has
claimed or can validly  claim title to any of the Company  Vehicles and (iii) it
has (or will cause to be)  delivered  to Buyer all  documents  necessary to file
with the  appropriate  governmental  agency to enable the Company  Subsidiary to
obtain a clear certificate of title to each Company Vehicle.

                            Stock Purchase Agreement

     This Stock  Purchase  Agreement  (this  "Agreement")  is entered into as of
August 22, 1997,  by and among WellTech  Eastern,  Inc., a Delaware  corporation
("Buyer"), and Robert E.  Mosley, Jr., Thelma Scoggin Mosley, Thomas A.  Mosley,
Nancy Evans Mosley, James R. Mosley, Dennis W. Mosley, and Melanie Ostrum Mosley
(collectively, the "Shareholders").

                                  WITNESSETH :

     Whereas,  Buyer is a corporation  duly organized and validly existing under
the laws of the State of Delaware,  with its principal  executive offices at Two
Tower Center, Tenth Floor, East Brunswick, New Jersey 08816;

     Whereas,  Mosley Well Service,  Inc. (the "Company") is a corporation  duly
organized and validly  existing  under the laws of the State of Louisiana,  with
its principal  executive  offices at 3000 Highway 80 East,  Haughton,  Louisiana
71037;
 
     Whereas,  the  Shareholders  own 20,500  shares (the  "Company  Shares") of
common stock,  par value $1.00 per share,  of the Company (the  "Company  Common
Stock"),  which constitutes all of the issued and outstanding  shares of capital
stock of the Company; and

     Whereas,  the  Shareholders  desire to sell to Buyer,  and Buyer desires to
purchase from the Shareholders,  all of the issued and outstanding capital stock
of the Company.

     Now,  Therefore,  in  consideration  of the  premises  and  of  the  mutual
covenants and agreements  herein  contained,  the parties hereto hereby agree as
follows:


                                   I. ARTICLE

                                Purchase and Sale

     A.  Purchase  and Sale of the  Company  Shares.  Subject  to the  terms and
conditions of this Agreement, on the date hereof, the Shareholders agree to sell
and convey to Buyer,  free and clear of all Encumbrances (as defined in Section
hereof),  and Buyer agrees to purchase and accept from the Shareholders,  all of
the Company Shares.  In consideration  of the sale of the Company Shares,  Buyer
shall pay to the  Shareholders a purchase  price of  $21,000,000  (the "Purchase
Price") in cash by wire transfer of immediately  available  funds,  and the Cash
Adjustment  Payment (as defined in Section hereof),  if any, in accordance with
Section hereof.

     A.  Adjustment  of Purchase  Price.  Buyer  shall cause to be prepared  and
delivered to the Shareholders a consolidated  balance sheet of the Company as of
the date  hereof  (the  "Final  Balance  Sheet")  within 60 days  after the date
hereof,  which  balance  sheet will be prepared  in  accordance  with  generally
accepted  accounting  principles,  consistently  applied in all respects  (which
shall not include any reserve or accruals for employee termination costs). Buyer
and the Shareholders  shall jointly review the Final Balance Sheet, and endeavor
in good faith to resolve all  disagreements  regarding  the entries  thereon and
reach a final determination  thereof within 90 days from the date hereof. In the
event that the  parties  cannot  agree on the  entries to be placed on the Final
Balance Sheet,  the dispute will be resolved by an independent  accounting  firm
mutually  agreed to by the  Shareholders  and Buyer  (such  agreement  not to be
unreasonably  withheld  or  delayed)  whose  resolution  shall be binding on and
enforceable  against the parties  hereto.  Within 10 days of reaching such final
determination, the following adjusting payments shall be made:

     (1) If the Final Net Current  Value of the  Company (as defined  below) (a)
exceeds  $1,000,000,  Buyer  shall pay to the  Shareholders  the  amount of such
excess  (the "Cash  Adjustment  Payment")  or (b) is less than  $1,000,000,  the
Shareholders  shall pay,  pro rata  according to each  Shareholder's  percentage
ownership of the Company  immediately  prior to the Closing (as defined herein),
to Buyer the amount of such difference; and

     (2) An amount equal to the capital  expenditures  made by the Company since
the Buyer's letter of intent dated July 17,  1997 (the "Letter") and approved by
the  Buyer  in  its  sole  and  absolute   discretion  (the  "Approved   Capital
Expenditures") shall be paid to the Shareholders.

     The term "Final Net Current Value of the Company" means the dollar value of
the amount by which the "Total  Current  Assets" plus the "Total Other  Assets,"
excluding  "Land," as recorded on the Final  Balance  Sheet,  exceeds the "Total
Liabilities,"  excluding  "Income Taxes  Payable,"  but including  $___________,
representing  the aggregate amount of the payment of debt of the Company made by
Buyer at the  Closing,  as  recorded  on the Final  Balance  Sheet.  The parties
expressly agree that the Cash Adjustment Payment will not include any income tax
liability of the Company for 1997.

     A. Closing. Consummation of the transactions contemplated by this Agreement
(the "Closing") shall take place at the offices of Bank One, N.A. in Shreveport,
Louisiana on the date hereof (the "Closing Date"), unless another time, place or
date is agreed to by the Shareholders and the Buyer.

     A. Closing Deliveries.  At the Closing,  (a) the Shareholders shall deliver

powers duly executed in blank  sufficient and in good form to properly  transfer
such shares to Buyer, (b) the Shareholders and Buyer shall have delivered to one
another all other  documents,  instruments and agreements as required under this
Agreement,  (c) Buyer shall deliver to the  Shareholders the cash purchase price
payable at Closing as  provided in  Section  by wire  transfer  of  immediately

     A.  Indemnification by the Shareholders.  In addition to any other remedies
available  to Buyer under this  Agreement,  or at law or in equity,  each of the
Shareholders shall jointly and severally indemnify, defend and hold harmless the
Company,  Buyer and their affiliates and their respective  officers,  directors,
employees,  agents  and  stockholders  (collectively,   the  "Buyer  Indemnified
Parties"),  against  and with  respect to any and all  claims,  costs,  damages,
losses, expenses, obligations,  liabilities, recoveries, suits, causes of action
and deficiencies, including interest, penalties and reasonable fees and expenses
of attorneys,  consultants  and experts  (collectively,  the "Damages") that the
Buyer  Indemnified  Parties shall incur or suffer,  which arise,  result from or
relate to any breach by any of the Shareholders of (or the failure of any of the
Shareholders to perform) their respective representations, warranties, covenants
or agreements  in this  Agreement or in any  schedule,  certificate,  exhibit or
other  instrument  furnished or  delivered  to Buyer by any of the  Shareholders
under this Agreement.

     A. Indemnification by Buyer. In addition to any other remedies available to
the  Shareholders  under this  Agreement,  or at law or in equity,  Buyer  shall
indemnify,  defend and hold harmless each of the  Shareholders  against and with
respect to any and all  Damages  that such  indemnitees  shall  incur or suffer,
which  arise,  result  from or relate to any  breach  of, or failure by Buyer to
perform, any of its representations, warranties, covenants or agreements in this
Agreement or in any schedule, certificate, exhibit or other instrument furnished
or  delivered  to any of the  Shareholders  by or on behalf of Buyer  under this
Agreement.

     A. Indemnification  Procedure. In the event that any party hereto discovers
or otherwise becomes aware of an  indemnification  claim arising under Article 4
of this  Agreement,  such  indemnified  party shall give  written  notice to the
indemnifying  party,  specifying  such claim,  and may  thereafter  exercise any
remedies available to such party under this Agreement;  provided,  however, that
the failure of any indemnified party to give notice as provided herein shall not
relieve the indemnifying party of any obligations  hereunder,  to the extent the
indemnifying party is not materially prejudiced thereby. Further, promptly after
receipt by an indemnified  party hereunder of written notice of the commencement
of any action or  proceeding  with respect to which a claim for  indemnification
may be made pursuant to Article 4 hereof,  such  indemnified  party shall,  if a
claim in respect  thereof is to be made  against any  indemnifying  party,  give
written  notice to the  latter of the  commencement  of such  action;  provided,
however,  that the failure of any  indemnified  party to give notice as provided
herein shall not relieve the indemnifying party of any obligations hereunder, to
the extent the indemnifying party is not materially  prejudiced thereby. In case
any such action is brought against an indemnified  party, the indemnifying party
shall be entitled to participate in and to assume the defense  thereof,  jointly
with any other indemnifying party similarly notified,  to the extent that it may
wish, with counsel reasonably  satisfactory to such indemnified party, and after
such  notice  from  the  indemnifying  party  to such  indemnified  party of its
election so to assume the defense thereof,  the indemnifying  party shall not be
liable to such  indemnified  party for any legal or other expenses  subsequently
incurred  by the  latter in  connection  with the  defense  thereof  unless  the
indemnifying  party has failed to assume the defense of such claim and to employ
counsel  reasonably  satisfactory to such  indemnified  person.  An indemnifying
party who elects not to assume  the  defense of a claim  shall not be liable for
the fees and  expenses of more than one counsel in any single  jurisdiction  for
all parties indemnified by such indemnifying party with respect to such claim or
with respect to claims separate but similar or related in the same  jurisdiction
arising  out  of  the  same  general  allegations.  Notwithstanding  any  of the
foregoing to the contrary,  the indemnified party will be entitled to select its
own  counsel  and assume the  defense  of any action  brought  against it if the
indemnifying  party  fails to  select  counsel  reasonably  satisfactory  to the
indemnified  party,  the expenses of such defense to be paid by the indemnifying
party.  No  indemnifying  party shall  consent to entry of any judgment or enter
into  any  settlement  with  respect  to a  claim  without  the  consent  of the
indemnified party, which consent shall not be unreasonably  withheld,  or unless
such judgment or settlement includes as an unconditional term thereof the giving
by the  claimant or plaintiff  to such  indemnified  party of a release from all
liability  with respect to such claim.  No  indemnified  party shall  consent to
entry of any  judgment  or enter into any  settlement  of any such  action,  the
defense of which has been assumed by an indemnifying party,  without the consent
of such indemnifying party, which consent shall not be unreasonably  withheld or
delayed.

     2.1 Term Loans.  Subject to the terms and conditions hereof, each Term Loan
Lender  severally  agrees to make a term loan (a "Term Loan") to the Borrower on
the  Closing  Date in an  amount  not to  exceed  the  amount  of the Term  Loan
Commitment  of  such  Lender.  The  Term  Loans  may  from  time  to time be (a)
Eurodollar  Loans,  (b)  Base  Rate  Loans  or  (c)  a combination  thereof,  as
determined  by  the  Borrower  and  notified  to  the  Administrative  Agent  in
accordance with Sections 2.2 and 2.10.

     2.2  Procedure  for  Term  Loan  Borrowing.  The  Borrower  shall  give the
Administrative  Agent  irrevocable  notice (which notice must be received by the
Administrative  Agent prior to 10:00 A.M.,  New York City time, one Business Day
prior to the  anticipated  Closing Date)  requesting  that the Term Loan Lenders
make Term Loans on the Closing Date and specifying (a) the amount to be borrowed
and (b) the Closing Date. Upon receipt of such notice, the Administrative  Agent

New York City  time,  on the  Closing  Date,  each Term Loan  Lender  shall make
available to the Administrative Agent at its office specified in Section 10.2 an
amount in immediately  available funds equal to the Term Loan to be made by such
Lender. The Administrative  Agent shall on such date by 2:00 P.M., New York City
time, make available to the Borrower, in accordance with the instructions of the
Borrower,  in like  funds as  received  by the  Administrative  Agent,  all such
amounts made available to the Administrative Agent by the Term Loan Lenders.

hereof,  each Revolving  Credit Lender severally agrees to make revolving credit
loans  ("Revolving  Credit  Loans") to the Borrower from time to time during the
Revolving Credit Commitment  Period in an aggregate  principal amount at any one
time outstanding  which, when added to such Lender's Revolving Credit Percentage
of the L/C  Obligations  then  outstanding,  does not  exceed the amount of such
Lender's  Revolving Credit  Commitment.  During the Revolving Credit  Commitment
Period,  the Borrower may use the  Revolving  Credit  Commitments  by borrowing,
prepaying the Revolving Credit Loans in whole or in part, and  reborrowing,  all
in accordance with the terms and conditions hereof.

     (b) The  Revolving  Credit  Loans may from  time to time be (i)  Eurodollar
Loans, (ii) Base Rate Loans or (iii) a combination thereof, as determined by the
Borrower and notified to the  Administrative  Agent in accordance  with Sections
2.4 and  2.10,  provided  that  no  Revolving  Credit  Loan  shall  be made as a
Eurodollar  Loan after the day that is one month prior to the  Revolving  Credit
Termination  Date. (c) The Revolving  Credit  Commitments  shall be reduced (and
each Revolving  Credit Lender's  Revolving  Credit  Commitment  shall be ratably
reduced) on each anniversary of the Closing Date, commencing with the third such
anniversary, to the amount set forth opposite such anniversary below:

                           Anniversary                  Amount

     2.4 Procedure for Revolving Credit Borrowing. The Borrower may borrow under
the Revolving Credit  Commitments  during the Revolving Credit Commitment Period
on any Business Day,  provided that the Borrower  shall give the  Administrative
Agent  irrevocable  notice (which notice must be received by the  Administrative
Agent prior to 12:00 Noon,  New York City time, (a) three Business Days prior to
the requested  Borrowing  Date,  if all or any part of the  requested  Revolving
Credit  Loans are to be  Eurodollar  Loans or (b) one  Business Day prior to the
requested Borrowing Date, otherwise),  specifying (i) the amount to be borrowed,
(ii) the  requested  Borrowing  Date,  (iii)  whether the  borrowing is to be of
Eurodollar  Loans,  Base Rate Loans,  or a  combination  thereof and (iv) if the
borrowing  is to be  entirely  or partly of  Eurodollar  Loans,  the  respective
amounts  of each such Type of Loan and the  respective  lengths  of the  initial
Interest Periods therefor. Each borrowing under the Revolving Credit Commitments
shall be in an amount equal to (x) in the case of Base Rate Loans, $1,000,000 or
a whole multiple thereof (or, if the then Available Revolving Credit Commitments
are less than $1,000,000,  such lesser amount) and (y) in the case of Eurodollar
Loans,  $5,000,000 or a whole  multiple of $1,000,000  in excess  thereof.  Upon
receipt of any such notice from the  Borrower,  the  Administrative  Agent shall
promptly  notify each Revolving  Credit Lender  thereof.  Each Revolving  Credit
Lender will make the amount of its pro rata share of each borrowing available to
the  Administrative  Agent for the account of the  Borrower at the office of the
Administrative  Agent  specified in Section  10.2 prior to 11:00 A.M.,  New York
City time, on the Borrowing Date requested by the Borrower in funds  immediately
available  to the  Administrative  Agent.  The  aggregate  of the  amounts  made
available to the Administrative  Agent by the Revolving Credit Lenders will then
be made available to the Borrower by the Administrative Agent in accordance with
the instructions of the Borrower in like funds as received by the Administrative
Agent.

     2.5  Commitment   Fees,  etc.  (a)  The  Borrower  agrees  to  pay  to  the
Administrative  Agent  for  the  account  of  each  Revolving  Credit  Lender  a
commitment  fee for the period from and  including  the Closing Date to the last
day of the Revolving Credit  Commitment  Period,  computed at the rate per annum
set forth  under the  heading  "Commitment  Fee Rate" on Annex I on the  average
daily amount of the Available  Revolving Credit Commitment of such Lender during
the period for which payment is made,  payable  quarterly in arrears on the last
day of each  March,  June,  September  and  December  and on the last day of the
Revolving  Credit  Commitment  Period,  commencing on the first of such dates to
occur after the date hereof.

     (b)  The  Borrower  agrees  to pay to  the  Arranger  the  fees  and  other
compensation in the amounts and on the dates previously  agreed to in writing by
the Borrower and the Arranger.

     (c) The Borrower agrees to pay to the Administrative  Agent the fees in the
amounts and on the dates  agreed to in writing from time to time by the Borrower
and the Administrative Agent.

     (d) The  Borrower  agrees  to pay to the  Collateral  Agent the fees in the
amount and on the dates  agreed to in writing  from time to time by the Borrower
and the Collateral Agent.

     2.6  Repayment  of  Loans;  Evidence  of  Debt.  (a)  The  Borrower  hereby
unconditionally  promises to pay to the Administrative  Agent for the account of
the appropriate  Lender (i) the then unpaid  principal  amount of each Revolving
Credit Loan of such  Revolving  Credit  Lender on the last day of the  Revolving
Credit  Commitment  Period (or such earlier date on which the  Revolving  Credit
Loans  become due and  payable  pursuant  to  Section 8) and (ii) the  principal
amount of the Term Loans of such Term Loan Lender,  in 25 consecutive  quarterly
installments,  each of which installments for each Lender shall be such Lender's
Term Loan Percentage of the amount for such  installment  payment date set forth
on the amortization  schedule set forth on Schedule 2.6,  commencing on June 30,
1998 and on the last day of each March, June,  September and December thereafter
(or on such earlier date on which the then unpaid  principal  amount of the Term
Loans become due and payable pursuant to Section 8). The Borrower hereby further
agrees to pay interest on the unpaid  principal amount of the Loans from time to
time outstanding from the date hereof until payment in full thereof at the rates
per annum, and on the dates, set forth in Section 2.12.

     (b) Each Lender shall  maintain in  accordance  with its usual  practice an
account or  accounts  evidencing  indebtedness  of the  Borrower  to such Lender
resulting from each Loan of such Lender from time to time, including the amounts
of  principal  and  interest  payable  and paid to such Lender from time to time
under this Agreement.

     (c) The Administrative Agent, on behalf of the Borrower, shall maintain the
Register  pursuant to Section 10.6(e) and a subaccount  therein for each Lender,
in which shall be recorded (i) the amount of each Revolving Credit Loan and Term
Loan made  hereunder,  the Type  thereof  and each  Interest  Period  applicable
thereto,  (ii) the amount of any  principal  or  interest  due and payable or to
become due and payable from the Borrower to each Lender hereunder and (iii) both
the amount of any sum received by the  Administrative  Agent  hereunder from the
Borrower and each Lender's share thereof.

     (d) The  entries  made in the  Register  and the  accounts  of each  Lender
maintained  pursuant  to  Section  2.6(b)  shall,  to the  extent  permitted  by
applicable  law, be prima facie  evidence  of the  existence  and amounts of the
obligations  of the  Borrower  therein  recorded;  provided,  however,  that the
failure of any Lender or the  Administrative  Agent to maintain  the Register or
any such  account,  or any error  therein,  shall not in any  manner  affect the
obligation of the Borrower to repay (with applicable interest) the Loans made to
such Borrower by such Lender in accordance with the terms of this Agreement. (e)
The Borrower  agrees that, upon the request to the  Administrative  Agent by any
Lender,  the  Borrower  will execute and deliver to such Lender (i) a promissory
note of the  Borrower  evidencing  any  Revolving  Credit  Loans of such Lender,
substantially in the form of Exhibit C-1 with appropriate  insertions as to date
and principal amount (a "Revolving Credit Note"),  and/or (ii) a promissory note
of the Borrower  evidencing any Term Loan of such Lender,  substantially  in the
form of Exhibit C-2 with appropriate  insertions as to date and principal amount
(a "Term Note"). A Note and the obligation  evidenced thereby may be assigned or
otherwise  transferred  in  whole  or in  part  only  by  registration  of  such
assignment or transfer of such Note and the obligation  evidenced thereby in the
Register (and each Note shall expressly so provide).  Any assignment or transfer
of all or part of an  obligation  evidenced by a Note shall be registered in the
Register only upon surrender for  registration  of assignment or transfer of the
Note  evidencing  such  obligation,  accompanied by an Assignment and Acceptance
substantially  in the form of Exhibit G duly  executed by the Assignor  thereof,
and thereupon one or more new Notes shall be issued to the  designated  Assignee
and the old Note shall be returned by the  Administrative  Agent to the Borrower
marked "cancelled". No assignment of a Note and the obligation evidenced thereby
shall be  effective  unless it shall have been  recorded in the  Register by the
Administrative Agent as provided in this Section 2.6(e).

     2.7 Optional Termination or Reduction of Revolving Credit Commitments.  The
Borrower shall have the right, upon not less than three Business Days' notice to
the Administrative Agent, to terminate the Revolving Credit Commitments or, from
time to time, to reduce the amount of the Revolving Credit Commitments; provided
that no such termination or reduction of Revolving Credit  Commitments  shall be
permitted  if,  after  giving  effect  thereto  and  to any  prepayments  of the
Revolving  Credit  Loans  made on the  effective  date  thereof,  the sum of the
Aggregate  Outstanding  Revolving  Extensions of Credit of all Revolving  Credit
Lenders would exceed the Revolving Credit  Commitments then in effect.  Any such
reduction  shall  be in an  amount  equal  to  $1,000,000,  or a whole  multiple
thereof,  and shall reduce  permanently the Revolving Credit Commitments then in
effect.

     2.8  Optional  Prepayments.  The  Borrower may at any time and from time to
time prepay the Loans, in whole or in part, without premium or penalty,  upon at
least three Business Days' irrevocable notice to the Administrative Agent by the
Borrower,  specifying  the  date  and  amount  of  prepayment  and  whether  the
prepayment is of  Eurodollar  Loans,  Base Rate Loans or a combination  thereof,
and, if of a combination thereof, the amount allocable to each, provided that if
a Eurodollar  Loan is prepaid on any day other than the last day of the Interest
Period applicable thereto the Borrower shall also pay any amounts owing pursuant
to Section 2.19. Upon receipt of any such notice, the Administrative Agent shall
promptly  notify each Lender  thereof.  If any such notice is given,  the amount
specified in such notice shall be due and payable on the date specified therein,
together  with  accrued  interest  to such date on the amount  prepaid.  Partial
prepayments of the Term Loans shall be applied to the remaining  installments in
the direct order of the  scheduled  payment date  thereof.  Notwithstanding  the
foregoing, so long as any Revolving Credit Loans are outstanding, each Term Loan
Lender  shall  have the right to refuse  all or any  portion  of any  prepayment
pursuant to this Section 2.8  allocable  to such  Lender's  Term Loans,  and the
amount so refused shall be applied to prepay the Revolving Credit Loans. Amounts
prepaid on account of the Term Loans may not be reborrowed.  Partial prepayments
of Term Loans and  Revolving  Credit  Loans shall be in an  aggregate  principal
amount of $1,000,000 or a whole multiple thereof.

     2.9 Mandatory Prepayments and Commitment  Reductions.  (a) If any senior or
subordinated  debt  securities  or  instruments  of the  Borrower  or any of its
Subsidiaries shall be issued or sold, or the Borrower or any of its Subsidiaries
shall incur any Indebtedness, after the Closing Date (except any debt securities
or instruments issued or sold or Indebtedness incurred pursuant to Section 7.2),
an amount equal to 100% of the Net Cash Proceeds thereof shall be applied on the
date of such issuance, sale or incurrence toward the prepayment of the Revolving
Credit Loans and, with respect to Net Cash Proceeds  thereof  received after the
third  anniversary of the Closing Date only, the prepayment of the Loans and the
reduction of the Revolving  Credit  Commitments as set forth in paragraph (f) of
this Section 2.9.  Nothing in this  paragraph  (a) shall be deemed to permit the
incurrence of Indebtedness not permitted by Section 7.2.

     (b) If any Capital Stock of the Borrower or any of its  Subsidiaries  shall
be issued or sold after the Closing Date  (except any Capital  Stock issued as a
part of the consideration of and in connection with a Permitted Acquisition), an
amount equal to 100% of the Net Cash  Proceeds  thereof  shall be applied on the
date of such  issuance or sale toward the  prepayment  of the  Revolving  Credit
Loans and, with respect to Net Cash Proceeds  thereof  received  after the third
anniversary  of the  Closing  Date  only,  the  prepayment  of the Loans and the
reduction of the Revolving  Credit  Commitments as set forth in paragraph (f) of
this Section 2.9; provided that, so long as no Default or Event of Default shall
have occurred and be  continuing,  the Borrower  shall not be required to reduce
the Revolving  Credit  Commitments  to less than  $80,000,000 as a result of the
application of Net Cash Proceeds pursuant to this paragraph (b).

     (c) If the  Borrower  or any of its  Subsidiaries  shall  receive  Net Cash
Proceeds from any Asset Sale or Recovery  Event after the Closing Date,  100% of
the Net Cash  Proceeds  thereof  shall  be  applied  on the  date  such Net Cash
Proceeds are received  toward the  prepayment  of the Loans and the reduction of
the Revolving  Credit  Commitments as set forth in paragraph (f) of this Section
2.9.  Notwithstanding the foregoing sentence, (i) no prepayment and reduction of
Revolving  Credit  Commitments  shall  be  required  in  respect  of  the  first
$2,000,000 in Net Cash Proceeds received from Asset Sales and Recovery Events in
any fiscal year  (excluding  any Net Cash  Proceeds  described in clause (ii) of
this  sentence)  and (ii) if no Default or Event of Default  shall have occurred
and be continuing and a  Reinvestment  Notice with respect to such Asset Sale or
Recovery Event has been delivered, to the extent that the Net Cash Proceeds from
any Asset Sale or Recovery Event are to be used to restore or replace the assets
in respect  of which an Asset Sale or  Recovery  Event has  occurred  within six
months from the date of such Asset Sale or Recovery  Event,  as  certified  by a
Responsible  Officer of the Borrower pursuant to such Reinvestment  Notice, such
Net Cash Proceeds  shall not be applied  toward the  prepayment of Loans and the
reduction of the Revolving Credit Commitments except as provided in the next two
succeeding  sentences.  If the Net Cash  Proceeds  from any  Reinvestment  Event
exceed  $5,000,000,  the Borrower shall deposit such Net Cash Proceeds in a cash
collateral   account   under  the   exclusive   dominion   and  control  of  the
Administrative  Agent as security for the  Obligations in accordance  with terms
and conditions  reasonably  satisfactory to the Administrative Agent pending the
reinvestment of such Net Cash Proceeds. On each Reinvestment Prepayment Date, an
amount  equal  to  the  Reinvestment  Prepayment  Amount  with  respect  to  the
applicable  Reinvestment  Event shall be applied  toward the  prepayment  of the
Loans and the  reduction of the  Revolving  Credit  Commitments  as set forth in
paragraph (f) of this Section 2.9.

     (d) If, for any  fiscal  year of the  Borrower  ending on or after June 30,
2000,  there shall be Excess Cash Flow,  the  Borrower  shall,  on the  relevant
Excess Cash Flow Application  Date, apply toward the prepayment of the Loans and
the reduction of the Revolving Credit  Commitments as set forth in paragraph (f)
of this  Section 2.9 an amount  equal to (i) 50% of such Excess Cash Flow if the
Consolidated  Leverage  Ratio at the end of the  relevant  fiscal  year shall be
greater  than or equal to 3.00 to 1.00 or (ii) 25% of such  Excess  Cash Flow if
the Consolidated  Leverage Ratio at the end of the relevant fiscal year shall be
less than 3.00 to 1.00. Each such  prepayment and commitment  reduction shall be
made on a date (an  "Excess  Cash Flow  Application  Date")  no later  than five
Business  Days  after  the  earlier  of (i) the  date  on  which  the  financial
statements  of the  Borrower  referred to in Section  6.1(a) for the fiscal year
with  respect to which such  prepayment  is made are required to be delivered to
the Lenders and (ii) the date such financial statements are actually delivered.

     (e) If any Convertible Subordinated Debentures are outstanding on April 30,
2003,  the Borrower  shall prepay the Term Loans in full on such date,  together
with all accrued  interest  thereon and all amounts payable  pursuant to Section
2.19 in connection with such prepayment.

     (f)  Amounts to be  applied in  connection  with  prepayments  of Loans and
Revolving Credit  Commitment  reductions made pursuant to this Section 2.9 shall
be applied,  first, to prepay the Revolving Credit Loans and reduce  permanently
the Revolving Credit Commitments,  pro rata according to the outstanding amounts
of Revolving Credit  Commitments,  except for amounts to be applied prior to the
third anniversary of the Closing Date pursuant to paragraphs (a) and (b) of this
Section  2.9  which  shall  be  applied  only  toward  prepayment  of  the  then
outstanding  Revolving Credit Loans and not to reduce  permanently the Revolving
Credit  Commitments,  and,  second,  after the Aggregate  Outstanding  Revolving
Extensions of Credit and the Revolving  Credit  Commitments have been reduced to
zero, to prepay the Term Loans pro rata according to the  outstanding  principal
amounts thereof. Any such reduction of the Revolving Credit Commitments shall be
accompanied by prepayment of the Revolving  Credit Loans to the extent,  if any,
that the sum of the Aggregate  Outstanding Revolving Extensions of Credit of all
Revolving  Credit Lenders exceeds the amount of the aggregate  Revolving  Credit
Commitments as so reduced,  provided that if the aggregate  principal  amount of
Revolving  Credit Loans then  outstanding is less than the amount of such excess
(because L/C Obligations  constitute a portion thereof),  the Borrower shall, to
the extent of the balance of such excess,  replace outstanding Letters of Credit
and/or deposit an amount in cash in a cash collateral  account  established with
the Administrative  Agent for the benefit of the Lenders on terms and conditions
satisfactory  to the  Administrative  Agent.  Amounts  on  deposit  in the  cash
collateral  account shall be invested as directed by the Borrower subject to the
approval of the  Administrative  Agent, which approval shall not be unreasonably
withheld.  The application of any prepayment  pursuant to this Section 2.9 shall
be made first to Base Rate Loans and second to Eurodollar  Loans,  provided that
at the  request  of the  Borrower  the  application  of  any  prepayment  to any
Eurodollar  Loan may be delayed until the end of an Interest Period (or Interest
Periods)  so that such  application  does not  result in the  incurrence  by any
Lender of any loss or expense  under Section  2.19,  and during such delay,  the
Administrative  Agent  shall  hold  the  amount  of  such  prepayment  in a cash
collateral  account.  Amounts  prepaid in  respect  of the Term  Loans  shall be
applied to installments thereof pro rata according to the outstanding  principal
amounts  thereof.  Amounts  prepaid  on  account  of the Term  Loans  may not be
reborrowed.  Each  prepayment  of the  Loans  under  this  Section  2.9 shall be
accompanied  by accrued  interest to the date of such  prepayment  on the amount
prepaid.

     2.10 Conversion and Continuation  Options.  (a) The Borrower may elect from
time to time to  convert  Eurodollar  Loans to Base  Rate  Loans by  giving  the
Administrative  Agent at least two Business  Days' prior  irrevocable  notice of
such election, provided that any such conversion of Eurodollar Loans may only be
made on the last day of an Interest  Period with respect  thereto.  The Borrower
may elect from time to time to convert  Base Rate Loans to  Eurodollar  Loans by
giving the Administrative  Agent at least three Business Days' prior irrevocable
notice of such election. Any such notice of conversion to Eurodollar Loans shall
specify the length of the initial Interest Period therefor.  Upon receipt of any
such notice, the Administrative Agent shall promptly notify each Lender thereof.
All or any part of  outstanding  Eurodollar  Loans  and Base  Rate  Loans may be
converted as provided herein,  provided that (i) no Loan may be converted into a
Eurodollar Loan (A) when any Event of Default has occurred and is continuing and
the  Administrative  Agent has or the Required Lenders have determined in its or
their sole  discretion not to permit such a conversion or (B) having an Interest
Period  in  excess of one  month  prior to the date  which is 60 days  after the
Closing Date and (ii) no Loan may be converted into a Eurodollar  Loan after the
date that is one month prior to (y) the Revolving Credit  Termination Date, with
respect to Revolving  Credit  Loans and (z) the Term Loan  Maturity  Date,  with
respect to Term Loans.

     (b) Any  Eurodollar  Loans may be continued as such upon the  expiration of
the then current  Interest  Period with respect  thereto by the Borrower  giving
irrevocable  notice  to  the  Administrative   Agent,  in  accordance  with  the
applicable provisions of the term "Interest Period" set forth in Section 1.1, of
the length of the next Interest Period to be applicable to such Loans,  provided
that no  Eurodollar  Loan may be continued as such (i) when any Event of Default
has occurred and is continuing and the Administrative  Agent has or the Required
Lenders have  determined  in its or their sole  discretion  not to permit such a
continuation or (ii) after the date that is one month prior to (A) the Revolving
Credit  Termination  Date, with respect to the Revolving Credit Loans or (B) the
Term Loan Maturity Date, with respect to Term Loans, and provided, further, that
if the  Borrower  shall fail to give any required  notice as described  above in
this  paragraph  or if  such  continuation  is  not  permitted  pursuant  to the
preceding proviso such Loans shall be automatically converted to Base Rate Loans
on the last day of such then expiring Interest Period.

     2.11  Minimum   Amounts  and  Maximum   Number  of   Eurodollar   Tranches.
Notwithstanding  anything to the  contrary in this  Agreement,  all  borrowings,
conversions,  continuations and optional  prepayments of Loans hereunder and all
selections of Interest  Periods  hereunder  shall be in such amounts and be made
pursuant  to such  elections  so that,  (a) after  giving  effect  thereto,  the
aggregate principal amount of the Loans comprising each Eurodollar Tranche shall
be equal to $5,000,000 or a whole multiple of $1,000,000 in excess thereof,  (b)
no more than eight Eurodollar  Tranches in respect of the Revolving Credit Loans
shall be  outstanding  at any one time and (c) no more  than  twelve  Eurodollar
Tranches in respect of all Loans (including the Revolving Credit Loans) shall be
outstanding at any one time.

     2.12 Interest Rates and Payment Dates.  (a) Each Eurodollar Loan shall bear
interest for each day during each Interest Period with respect thereto at a rate
per  annum  equal  to the  Eurodollar  Rate  determined  for  such  day plus the
Applicable Margin.

     (b) Each Base Rate Loan shall bear  interest  at a rate per annum  equal to
the Base Rate plus the Applicable Margin.

     (c) If all or a  portion  of any  principal  of any  Loan or  Reimbursement
Obligations  shall not be paid when due  (whether  at the  stated  maturity,  by
acceleration  or  otherwise),  such amounts  shall bear interest at 2% above the
rate otherwise  applicable  thereto from the date of such non-payment until such
overdue principal is paid in full (as well after as before judgment).  If all or
a portion  of any  interest  shall not be paid when due  (whether  at the stated
maturity, by acceleration or otherwise),  such amounts shall bear interest at 2%
above the rate otherwise applicable to the Loans or Reimbursement Obligations on
which such interest accrued from the date of such non-payment until such overdue
principal  is paid in full  (as  well  after as  before  judgment).  If all or a
portion of any commitment fee or any other amount payable hereunder shall not be
paid when due (whether at the stated  maturity,  by  acceleration or otherwise),
such amounts shall bear interest at a rate which is 2% above the rate applicable
to Base Rate Loans which are Revolving  Credit Loans, in each case from the date
of such non-payment until such overdue commitment fee or other amount is paid in
full (as well after as before judgment).

     (d) Interest  shall be payable in arrears on each  Interest  Payment  Date,
provided that interest  accruing  pursuant to paragraph (c) of this Section 2.12
shall be payable from time to time on demand.

     2.13   Computation  of  Interest  and  Fees.  (a)  Interest  on  Loans  and
Reimbursement  Obligations,  commitment fees,  letter of credit  commissions and
interest  on  overdue  interest,  commitment  fees  and  other  amounts  payable
hereunder shall be calculated on the basis of a 360-day year for the actual days
elapsed,  except  that,  with respect to Base Rate Loans the rate of interest on
which is calculated on the basis of the Prime Rate,  the interest  thereon shall
be  calculated on the basis of a 365- (or 366-, as the case may be) day year for
the actual days elapsed.  The Administrative  Agent shall as soon as practicable
notify the Borrower and the Lenders of each  determination of a Eurodollar Rate.
Any change in the interest  rate on a Loan  resulting  from a change in the Base
Rate or the Eurocurrency  Reserve  Requirements shall become effective as of the
opening of  business  on the day on which such  change  becomes  effective.  The
Administrative  Agent shall as soon as  practicable  notify the Borrower and the
Lenders of the  effective  date and the amount of each such  change in  interest
rate.

     (b) Each  determination  of an interest  rate by the  Administrative  Agent
pursuant to any provision of this  Agreement  shall be conclusive and binding on
the Borrower and the Lenders in the absence of manifest error.

     2.14 Inability to Determine Interest Rate. If prior to the first day of any
Interest Period:

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

     (b) the  Administrative  Agent shall have received notice from the Required
Lenders  that  the  Eurodollar  Rate  determined  or to be  determined  for such
Interest  Period will not adequately and fairly reflect the cost to such Lenders
(as  conclusively  certified  by such  Lenders) of making or  maintaining  their
affected Loans during such Interest Period,

     the  Administrative  Agent shall give telecopy or telephonic notice thereof
to the  Borrower  and the  Lenders as soon as  practicable  thereafter.  If such
notice is given (x) any Eurodollar  Loans  requested to be made on the first day
of such  Interest  Period shall be made as Base Rate Loans,  (y) any  Loans that
were to  have  been  converted  on the  first  day of such  Interest  Period  to
Eurodollar  Loans shall be continued as Base Rate Loans and (z) any  outstanding
Eurodollar  Loans that were to be  continued  on the first day of such  Interest
Period as Eurodollar Loans shall be converted, on the first day of such Interest
Period,  to Base  Rate  Loans.  Until  such  notice  has been  withdrawn  by the
Administrative  Agent, no further Eurodollar Loans shall be made or continued as
such,  nor shall the  Borrower  have the right to  convert  Loans to  Eurodollar
Loans.

     2.15 Pro Rata  Treatment and Payments.  (a) Each  borrowing by the Borrower
from the  Lenders  hereunder,  each  payment by the  Borrower  on account of any
commitment fee and any reduction of the Commitments of the Lenders shall be made
pro rata according to the respective Term Loan  Percentages or Revolving  Credit
Percentages,  as the case may be, of the relevant Lenders. Except as provided in
Section 2.8, each payment (including each prepayment) by the Borrower on account
of principal of and interest on the Term Loans shall be made pro rata  according
to the respective  outstanding  principal amounts of the Term Loans then held by
the Term Loan Lenders.  Each payment (including each prepayment) by the Borrower
on account of principal of and interest on the  Revolving  Credit Loans shall be
made pro rata according to the respective  outstanding  principal amounts of the
Revolving Credit Loans then held by the Revolving  Credit Lenders.  Each payment
made at any time when any amount  hereunder is due and payable shall be made pro
rata  according to the  respective  amounts then due and payable to the Lenders.
All payments  (including  prepayments) to be made by the Borrower  hereunder and
under the Notes, whether on account of principal,  interest,  fees or otherwise,
shall be made without  setoff or  counterclaim  and shall be made prior to 12:00
Noon, New York City time, on the due date thereof to the  Administrative  Agent,
for the account of the Lenders,  at the Administrative  Agent's office specified
in Section  10.2,  in  Dollars  and in  immediately  available  funds.  Payments
received  by the  Administrative  Agent  after such time shall be deemed to have
been  received  on  the  next  Business  Day.  The  Administrative  Agent  shall
distribute  such payments to the Lenders  promptly upon receipt in like funds as
received. If any payment hereunder (other than payments on the Eurodollar Loans)
becomes due and payable on a day other than a Business  Day,  such payment shall
be extended to the next succeeding  Business Day. If any payment on a Eurodollar
Loan  becomes due and payable on a day other than a Business  Day,  the maturity
thereof shall be extended to the next succeeding  Business Day unless the result
of such extension  would be to extend such payment into another  calendar month,
in which event such payment shall be made on the immediately  preceding Business
Day. In the case of any  extension of any payment of  principal  pursuant to the
preceding  two  sentences,  interest  thereon  shall  be  payable  at  the  then
applicable rate during such extension.

     (b) Unless the Administrative  Agent shall have been notified in writing by
any Lender  prior to a borrowing  that such Lender will not make the amount that
would  constitute  its share of such borrowing  available to the  Administrative
Agent,  the  Administrative  Agent may assume  that such  Lender is making  such
amount available to the Administrative  Agent, and the Administrative Agent may,
in reliance upon such assumption, make available to the Borrower a corresponding
amount. If such amount is not made available to the Administrative  Agent by the
required  time on the  Borrowing  Date  therefor,  such Lender  shall pay to the
Administrative  Agent,  on demand,  such amount with interest  thereon at a rate
equal to the daily  average  Federal Funds  Effective  Rate for the period until
such Lender makes such amount immediately available to the Administrative Agent.
A certificate of the  Administrative  Agent submitted to any Lender with respect
to any amounts  owing under this  Section  2.15(b)  shall be  conclusive  in the
absence of manifest  error. If such Lender's share of such borrowing is not made
available to the Administrative  Agent by such Lender within three Business Days
of such  Borrowing  Date,  the  Administrative  Agent  shall also be entitled to
recover such amount with  interest  thereon at the rate per annum  applicable to
Base Rate Loans  hereunder,  on demand,  from the  Borrower  (together  with any
amounts due under  Section 2.19,  calculated as if such Lender's failure to fund
such amount were a failure of the  Borrower to borrow such amount  after  having
given  notice of such  borrowing).  Nothing  herein shall be deemed to limit the
rights of the Borrower against any defaulting Lender.

     (c) Unless the Administrative  Agent shall have been notified in writing by
the  Borrower  prior to the date of any payment  being made  hereunder  that the
Borrower  will  not  make  such  payment  to  the   Administrative   Agent,  the
Administrative  Agent may assume that the Borrower is making such  payment,  and
the  Administrative  Agent may, but shall not be required  to, in reliance  upon
such assumption,  make available to the Lenders their respective pro rata shares
of a  corresponding  amount.  If such payment is not made to the  Administrative
Agent by the Borrower  within three  Business  Days of such required  date,  the
Administrative  Agent shall be entitled to recover,  on demand, from each Lender
to which any amount which was made available pursuant to the preceding sentence,
such  amount  with  interest  thereon  at the rate per annum  equal to the daily
average Federal Funds  Effective  Rate.  Nothing herein shall be deemed to limit
the rights of the Administrative Agent or any Lender against the Borrower.

     2.16  Illegality.  Notwithstanding  any  other  provision  herein,  if  the
adoption of or any change in any Requirement of Law or in the  interpretation or
application  thereof  shall make it unlawful  for any Lender to make or maintain
Eurodollar  Loans as contemplated by this Agreement,  (a) the commitment of such
Lender hereunder to make Eurodollar Loans, continue Eurodollar Loans as such and
convert Base Rate Loans to Eurodollar Loans shall forthwith be suspended and (b)
such Lender's  Loans then  outstanding  as Eurodollar  Loans,  if any,  shall be
converted  automatically  to Base Rate Loans on the respective  last days of the
then current  Interest Periods with respect to such Loans or within such earlier
period as required by law. If any such conversion of a Eurodollar Loan occurs on
a day which is not the last day of the then current Interest Period with respect
thereto,  the Borrower shall pay to such Lender such amounts,  if any, as may be
required pursuant to Section 2.19.

     2.17  Requirements  of Law. (a) If after the date hereof the adoption of or
any change in any  Requirement  of Law or in the  interpretation  or application
thereof or  compliance  by any Lender with any request or directive  (whether or
not  having  the  force of law)  from  any  central  bank or other  Governmental
Authority made subsequent to the date hereof:

     (i shall subject any Lender to any tax of any kind  whatsoever with respect
to this  Agreement,  any Note,  any Letter of  Credit,  any  Application  or any
Eurodollar  Loan made by it, or change the basis of taxation of payments to such
Lender in respect  thereof (except for taxes covered by Section 2.18 and changes
in the rate of tax (whether characterized as income,  franchise or other tax) on
the overall net income of such Lender);

     (ii shall impose,  modify or hold applicable any reserve,  special deposit,
compulsory loan or similar requirement against assets held by, deposits or other
liabilities  in or for the account of,  advances,  loans or other  extensions of
credit by, or any other acquisition of funds by, any office of such Lender which
is not otherwise included in the determination of the Eurodollar Rate hereunder;
or

     (iii shall impose on such Lender any other condition;

     and the  result of any of the  foregoing  is to  increase  the cost to such
Lender,  by an  amount  which  such  Lender  deems to be  material,  of  making,
converting  into,  continuing  or  maintaining  Eurodollar  Loans or  issuing or
participating in Letters of Credit, or to reduce any amount receivable hereunder
in respect thereof, then, in any such case, the Borrower shall promptly pay such
Lender,  upon its demand,  any additional  amounts  necessary to compensate such
Lender  on an  after-tax  basis  for  such  increased  cost  or  reduced  amount
receivable.  If any Lender  becomes  entitled  to claim any  additional  amounts
pursuant to this Section 2.17,  it shall  promptly  notify the Borrower  (with a
copy to the Administrative  Agent) of the event by reason of which it has become
so entitled.

     (b) If any Lender shall have  determined that the adoption of or any change
in any Requirement of Law regarding capital adequacy or in the interpretation or
application thereof or compliance by such Lender or any corporation  controlling
such Lender with any request or directive regarding capital adequacy (whether or
not having the force of law) from any Governmental  Authority made subsequent to
the date  hereof  shall have the effect of  reducing  the rate of return on such
Lender's  or such  corporation's  capital as a  consequence  of its  obligations
hereunder  or under or in respect of any Letter of Credit to a level  below that
which such Lender or such corporation could have achieved but for such adoption,
change  or  compliance   (taking  into   consideration  such  Lender's  or  such
corporation's  policies with respect to capital adequacy) by an amount deemed by
such Lender to be material,  then from time to time,  after  submission  by such
Lender to the Borrower  (with a copy to the  Administrative  Agent) of a written
request  therefor,  the Borrower shall pay to such Lender such additional amount
or  amounts  as will  compensate  such  Lender  on an  after-tax  basis for such
reduction.

     (c) If any Lender becomes entitled to claim any additional amounts pursuant
to this  subsection,  it shall promptly  notify the Borrower (with a copy to the
Administrative Agent) of the event by reason of which it has become so entitled.
A certificate  as to any  additional  amounts  payable  pursuant to this Section
2.17,  together  with a  calculation  thereof  in  reasonable  detail,  shall be
submitted  by  the  affected  Lender  to  the  Borrower  (with  a  copy  to  the
Administrative Agent) and such certificate shall be conclusive in the absence of
manifest error.  The  obligations of the Borrower  pursuant to this Section 2.17
shall survive the termination of this Agreement and the payment of the Notes and
all other amounts payable hereunder.

     2.18 Taxes.  (a) All payments made by the Borrower under this Agreement and
the Notes shall be made free and clear of, and without  deduction or withholding
for or on  account  of,  any  present or future  income,  stamp or other  taxes,
levies,  imposts,  duties,  charges,  fees,  deductions or withholdings,  now or
hereafter imposed, levied,  collected,  withheld or assessed by any Governmental
Authority,  excluding net income taxes and franchise  taxes  (imposed in lieu of
net income taxes) imposed on the Administrative  Agent or any Lender as a result
of a present  or former  connection  between  the  Administrative  Agent or such
Lender and the jurisdiction of the Governmental  Authority  imposing such tax or
any political subdivision or taxing authority thereof or therein (other than any
such  connection  arising  solely from the  Administrative  Agent or such Lender
having  executed,  delivered or performed its  obligations or received a payment
under,  or enforced,  this  Agreement or any other Loan  Document).  If any such
non-excluded  taxes,  levies,  imposts,  duties,  charges,  fees,  deductions or
withholdings ("Non-Excluded Taxes") are required to be withheld from any amounts
payable to the Administrative  Agent or any Lender hereunder or under the Notes,
the  amounts so  payable to the  Administrative  Agent or such  Lender  shall be
increased to the extent necessary to yield to the  Administrative  Agent or such
Lender  (after  payment of all  Non-Excluded  Taxes)  interest or any such other
amounts  payable  hereunder  at the rates or in the  amounts  specified  in this
Agreement  and the  Notes,  provided,  however,  that the  Borrower  shall  make
payments  net of and after  deduction  for  Non-Excluded  Taxes and shall not be
required to increase any such amounts payable to any Non-U.S. Lender (as defined
below) that fails to comply with  Section  2.18(b).  Whenever  any  Non-Excluded
Taxes are  payable by the  Borrower,  as promptly  as  possible  thereafter  the
Borrower shall send to the  Administrative  Agent for its own account or for the
account of such  Lender,  as the case may be, a  certified  copy of an  original
official  receipt  received by the  Borrower  showing  payment  thereof.  If the
Borrower fails to pay any Non-Excluded  Taxes when due to the appropriate taxing
authority or fails to remit to the Administrative Agent the required receipts or
other  required   documentary   evidence,   the  Borrower  shall  indemnify  the
Administrative  Agent and the Lenders for any  Non-Excluded  Taxes,  incremental
taxes, interest or penalties that may become payable by the Administrative Agent
or any Lender as a result of any such  failure.  The  agreements in this Section
2.18 shall  survive the  termination  of this  Agreement  and the payment of the
Notes and all other amounts payable hereunder.

     (b) Each Lender (or  Transferee)  that is not a corporation  or partnership
created or organized in or under the laws of the United States,  any estate that
is subject to federal income taxation  regardless of the source of its income or
any trust  which is  subject  to the  supervision  of a court  within the United
States and the control of a United  States  fiduciary  as  described  in section
7701(a)(30) of the Code (a "Non-U.S.  Lender") shall deliver to the Borrower and
the Administrative  Agent (or, in the case of a Participant,  to the Lender from
which the related participation shall have been purchased) on or before the date
on which it becomes a party to this Agreement (or, in the case of a Participant,
on  or  before  the  date  on  which  such  Participant  purchases  the  related
participation) either:

     (A) (x) two duly  completed  and signed copies of either  Internal  Revenue
Service  Form 1001  (relating  to such  Non-U.S.  Lender and  entitling  it to a
complete  exemption from withholding of U.S. Taxes on all amounts to be received
by such Non-U.S. Lender pursuant to this Agreement and the other Loan Documents)
or Form 4224  (relating  to all amounts to be received by such  Non-U.S.  Lender
pursuant to this  Agreement  and the other Loan  Documents),  or  successor  and
related  applicable  forms,  as the case may be, and (y) two duly  completed and
signed  copies of Internal  Revenue  Service Form W-8 or W-9, or  successor  and
related applicable forms, as the case may be; or

     (B) in the  case of a  Non-U.S.  Lender  that is not a  "bank"  within  the
meaning of Section  881(c)(3)(A)  of the Code and that does not comply  with the
requirements of clause (A) hereof,  (x) a statement in the form of Exhibit F (or
such other form of statement as shall be reasonably requested by the Borrower or
the  Administrative  Agent from time to time) to the effect  that such  Non-U.S.
Lender is eligible for a complete exemption from withholding of U.S. Taxes under
Code Section  871(h) or 881(c),  and (y) two duly completed and signed copies of
Internal Revenue Service Form W-8 or successor and related applicable form.

     Further,  each  Non-U.S.  Lender  agrees to deliver to the Borrower and the
Administrative  Agent, and if applicable,  the assigning Lender (or, in the case
of a Participant,  to the Lender from which the related participation shall have
been purchased) two further duly completed and signed copies of such Forms 1001,
4224, W-8 or W-9, as the case may be, or successor and related applicable forms,
on or  before  the date that any such  form  expires  or  becomes  obsolete  and
promptly  after the  occurrence  of any event  requiring  a change from the most
recent form(s) previously  delivered by it to the Borrower or the Administrative
Agent (or,  in the case of a  Participant,  to the Lender from which the related
participation  shall have been purchased) in accordance  with applicable  United
States  laws and  regulations;  unless,  in any such case,  any change in law or
regulation  has occurred  subsequent  to the date such Lender  became a party to
this  Agreement  (or in the  case  of a  Participant,  the  date on  which  such
Participant  purchased the related  participation)  which renders all such forms
inapplicable or which would prevent such Lender (or  Participant)  from properly
completing  and  executing  any such form  with  respect  to it and such  Lender
promptly notifies the Borrower and the Administrative  Agent (or, in the case of
a Participant,  the Lender from which the related  participation shall have been
purchased) if it is no longer able to deliver,  or if it is required to withdraw
or cancel,  any form or  statement  previously  delivered by it pursuant to this
Section 2.18(b). A Non-U.S.  Lender shall not be required to deliver any form or
statement  pursuant  to the  immediately  preceding  sentences  in this  Section
2.18(b)  that such  Non-U.S.  Lender is not  legally  able to deliver  (it being
understood  and agreed that the Borrower  shall  withhold or deduct such amounts
from any payments  made to such  Non-U.S.  Lender that the  Borrower  reasonably
determines  are required by law and that  payments  resulting  from a failure to
comply with this  paragraph  (b) shall not be subject to payment or indemnity by
the Borrower pursuant to Section 2.18(a)).

     2.19  Indemnity.  The Borrower  agrees to indemnify each Lender and to hold
each Lender  harmless  from any loss or expense which such Lender may sustain or
incur as a consequence  of (a)default by the Borrower in making a borrowing of,
conversion into or continuation of Eurodollar Loans after the Borrower has given
a  notice  requesting  the  same  in  accordance  with  the  provisions  of this
Agreement,  (b)  default  by the  Borrower  in making any  prepayment  after the
Borrower has given a notice  thereof in accordance  with the  provisions of this
Agreement or (c) the making of a prepayment of  Eurodollar  Loans on a day which
is  not  the  last  day  of  an  Interest  Period  with  respect  thereto.  Such
indemnification  shall not exceed the sum of (i) an  amount equal to the excess,
if any, of (A) the amount of interest  which would have accrued on the amount so
prepaid,  or not so borrowed,  converted or  continued,  for the period from the
date of such prepayment or of such failure to borrow, convert or continue to the
last day of such  Interest  Period  (or,  in the case of a  failure  to  borrow,
convert or continue,  the Interest  Period that would have commenced on the date
of such failure) in each case at the applicable  rate of interest for such Loans
provided for herein (excluding, however, the Applicable Margin included therein,
if any) over (B) the  amount  of  interest  (as  reasonably  determined  by such
Lender)  which would have  accrued to such Lender on such amount by placing such
amount on deposit for a comparable  period with leading  banks in the  interbank
eurodollar  market plus (ii) any  transaction costs of such Lender in connection
with the related  funding or  redeployment  of funds.  A  certificate  as to any
amounts  payable  pursuant to this Section  2.19,  together  with a  calculation
thereof in reasonable detail, shall be submitted to the Borrower by any affected
Lender and such  certificate  shall be  conclusive  in the  absence of  manifest
error.  This covenant  shall survive the  termination  of this Agreement and the
payment of the Notes and all other amounts payable hereunder.

     2.20 Change of Lending Office. Each Lender agrees that, upon the occurrence
of any event giving rise to the operation of Section 2.16,  2.17(a) or 2.18 with
respect to such Lender,  it will, if requested by the Borrower,  use  reasonable
efforts (subject to overall policy  considerations  of such Lender) to designate
another  lending  office for any Loans affected by such event with the object of
avoiding the consequences of such event;  provided that such designation is made
on terms that,  in the sole  judgment of such Lender,  cause such Lender and its
lending  office(s)  to  suffer  no  material   economic,   legal  or  regulatory
disadvantage,  and  provided,  further,  that nothing in this Section 2.20 shall
affect or postpone any of the  obligations  of the Borrower or the rights of any
Lender pursuant to Section 2.16, 2.17(a) or 2.18.

     2.21 Use of Proceeds. The Borrower shall use the proceeds of the Loans only
in the manner expressly contemplated by Section 4.16.

     2.22  Replacement  of  Lenders.  If no Event of Default  then  exists,  the
Borrower  may  replace  any Lender (the  "Replaced  Lender") if an event  occurs
giving rise to the operation of Section 2.16 or Section  2.17,  which results in
the  Replaced  Lender  charging to Borrower  increased  costs in excess of those
being  generally  charged by the other  Lenders  and such  Lender is not able to
eliminate the increased  costs  pursuant to Section  2.20.  The Replaced  Lender
shall be  replaced  with one or more  banks,  financial  institutions,  or other
entities which are  reasonably  acceptable to the  Administrative  Agent (each a
"Replacement Lender") under the terms set out in Section 10.6(c). Upon execution
of the  Assignment  and Acceptance  referred to in Section  10.6(c),  payment of
amounts referred to in Section 10.6(c),  and delivery to the Replacement  Lender
of the appropriate  Note or Notes executed by Borrower,  the Replacement  Lender
shall become a Lender  under this  Agreement  and the  Replaced  Lender shall no
longer be a Lender under this Agreement,  except with respect to indemnification
provisions under this Agreement, which shall survive as to such Replaced Lender.


                          SECTION 3. LETTERS OF CREDIT

     3.1 L/C Commitment.  (a) Prior to the date hereof,  Norwest Bank has issued
the Letters of Credit listed on Schedule 3.1 (the "Existing Letters of Credit"),
and subject to the terms and conditions hereof, the Lender designated as Issuing
Lender  hereunder,  in reliance on the agreements of the other Revolving  Credit
Lenders set forth in Section 3.4(a), agrees to issue letters of credit (together
with the Existing Letters of Credit, "Letters of Credit") for the account of the
Borrower,  or for  the  joint  and  several  account  of the  Borrower  and  any
Subsidiary, on any Business Day during the Revolving Credit Commitment Period in
such form as may be requested by the Borrower and approved  from time to time by
the  Issuing  Lender;  provided,  that  such  approval  may not be  unreasonably
withheld, delayed or conditioned; and provided, further, that the Issuing Lender
shall have no  obligation  to issue any Letter of Credit if, after giving effect
to such  issuance,  (i) the L/C  Obligations  would exceed the L/C Commitment or
(ii) the Aggregate  Outstanding  Revolving Extensions of Credit would exceed the
aggregate  Revolving  Credit  Commitments.  Each  Letter of Credit  shall (i) be
denominated in Dollars,  (ii) be either (x) a standby letter of credit issued to
support (I) obligations of the Borrower or any of its  Subsidiaries,  contingent
or  otherwise,  which  finance  the  working  capital or  business  needs of the
Borrower or its Subsidiaries or (II) performance obligations of the Borrower and
its Subsidiaries,  in each case,  incurred in the ordinary course of business (a
"Standby Letter of Credit"),  or (y) a commercial letter of credit in respect of
the purchase of goods or services by the Borrower or any of its  Subsidiaries in
the ordinary course of business (a "Commercial Letter of Credit"),  (iii) expire
no later than five Business Days prior to the Revolving Credit  Termination Date
and (iv) expire no later than 365 days after its date of issuance, provided that
any Letter of Credit with a 365-day duration may provide for the renewal thereof
at the election of the Borrower (in accordance with procedures to be established
by the Issuing  Lender) for additional  365-day  periods (which shall not expire
later than five Business Days prior to the Revolving Credit  Termination  Date).
(b) Each Letter of Credit  issued after the Closing Date shall be subject to the
Uniform Customs and, to the extent not inconsistent  therewith,  the laws of the
State of New York.

     3.2 Procedure for Issuance of Letter of Credit.  The Borrower may from time
to time request that the Issuing  Lender issue a Letter of Credit by  delivering
to the Issuing Lender at its address for notices specified herein an Application
therefor,  completed to the  satisfaction of the Issuing Lender,  and such other
certificates,  documents and other papers and  information as the Issuing Lender
may request.  Upon receipt of any  Application,  the Issuing Lender will process
such  Application  and  the   certificates,   documents  and  other  papers  and
information  delivered  to it in  connection  therewith in  accordance  with its
customary  procedures and shall  promptly  issue the Letter of Credit  requested
thereby  (but in no event  shall the  Issuing  Lender be  required  to issue any
Letter of Credit  earlier  than three  Business  Days  after its  receipt of the
Application therefor and all such other certificates, documents and other papers
and  information  relating  thereto) by issuing  the  original of such Letter of
Credit  to the  beneficiary  thereof  or as  otherwise  may be  agreed to by the
Issuing Lender and the Borrower. The Issuing Lender shall furnish a copy of such
Letter of Credit to the Borrower promptly  following the issuance  thereof.  The
Issuing Lender shall promptly furnish to the  Administrative  Agent, which shall
in turn promptly furnish to the Lenders,  notice of the issuance of each Standby
Letter of Credit  (including the amount thereof).  On each L/C Fee Payment Date,
the Issuing Lender shall promptly  furnish to the  Administrative  Agent,  which
shall in turn  promptly  furnish to the Lenders,  notice of the  aggregate  face
amount of the Commercial Letters of Credit outstanding on such date.

     3.3 Fees,  Commissions  and Other Charges.  (a) The Borrower agrees that it
will pay a commission on all  outstanding  Letters of Credit at a rate per annum
equal to 1/8 of 1% above the  Applicable  Margin then in effect with  respect to
Revolving Credit Loans that are Eurodollar Loans of the face amount of each such
Letter of Credit,  of which 1/8 of 1% per annum  will be a fronting  fee for the
account of the Issuing  Lender,  and the remainder  will be shared ratably among
the  Revolving   Credit  Lenders  in  accordance  with  their  Revolving  Credit
Percentages, payable quarterly in arrears on each L/C Fee Payment Date after the
issuance date.

     (b) In addition to the foregoing fees and commissions,  the Borrower agrees
that it shall pay or reimburse the Issuing Lender  promptly upon demand for such
normal  and  customary  costs and  expenses  as are  incurred  or charged by the
Issuing Lender in issuing, negotiating, effecting payment under, or amending any
Letter of Credit.

     (c) The Administrative Agent shall, promptly following its receipt thereof,
distribute  to the  Issuing  Lender  and  the  L/C  Participants  all  fees  and
commissions  received by the Administrative  Agent for their respective accounts
pursuant to this Section.

     3.4 L/C Participation.  (a) Effective on the Closing Date in respect of the
Existing  Letters of Credit,  and  effective on the date of issuance  thereof in
respect of each Letter of Credit issued  hereunder  after the Closing Date,  the
Issuing Lender in respect of each Letter of Credit  irrevocably  agrees to grant
and hereby grants to each L/C Participant, and, to induce such Issuing Lender to
issue Letters of Credit hereunder,  each L/C Participant  irrevocably  agrees to
accept and purchase and hereby accepts and purchases  from such Issuing  Lender,
on the terms and conditions  hereinafter  stated, for such L/C Participant's own
account and risk an undivided interest equal to such L/C Participant's Revolving
Credit  Percentage in such Issuing  Lender's  obligations  and rights under such
Letter of  Credit  and the  amount of each  draft  paid by such  Issuing  Lender
thereunder.  Each L/C Participant  unconditionally  and irrevocably  agrees with
such Issuing Lender in respect of each Letter of Credit that, if a draft is paid
under any Letter of Credit issued by such Issuing  Lender for which such Issuing
Lender is not reimbursed in full by the Borrower in accordance with the terms of
this  Agreement,  such L/C  Participant  shall pay to such  Issuing  Lender upon
demand at such Issuing Lender's  address for notices  specified herein an amount
equal to such L/C  Participant's  Revolving  Credit  Percentage of the amount of
such draft, or any part thereof, which is not so reimbursed.

     (b) If any amount required to be paid by any L/C Participant to the Issuing
Lender pursuant to Section 3.4(a) in respect of any unreimbursed  portion of any
payment  made by the  Issuing  Lender  under any Letter of Credit is paid to the
Issuing  Lender  within three  Business Days after the date such payment is due,
such L/C  Participant  shall pay to the Issuing Lender on demand an amount equal
to the product of (i) such amount,  times (ii) the daily  average  Federal Funds
Effective  Rate during the period from and  including  the date such  payment is
required  to the date on which such  payment  is  immediately  available  to the
Issuing  Lender,  times (iii) a fraction the numerator of which is the number of
days that elapse during such period and the  denominator of which is 360. If any
such  amount  required  to be paid by any L/C  Participant  pursuant  to Section
3.4(a) is not made  available  to the  Issuing  Lender  by such L/C  Participant
within  three  Business  Days after the date such  payment is due,  the  Issuing
Lender shall be entitled to recover from such L/C Participant,  on demand,  such
amount with interest thereon calculated from such due date at the rate per annum
applicable  to  Revolving  Credit  Loans that are Base Rate Loans  hereunder.  A
certificate of the Issuing Lender  submitted to any L/C Participant with respect
to any amounts  owing under this Section  shall be  conclusive in the absence of
manifest error.

     (c) Whenever,  at any time after the Issuing  Lender has made payment under
any  Letter of Credit and has  received  from any L/C  Participant  its pro rata
share of such payment in  accordance  with Section  3.4(a),  the Issuing  Lender
receives any payment related to such Letter of Credit (whether directly from the
Borrower or otherwise,  including  proceeds of collateral applied thereto by the
Issuing  Lender),  or any payment of interest  on account  thereof,  the Issuing
Lender  will  distribute  to such L/C  Participant  its pro rata share  thereof;
provided that in the event that any such payment  received by the Issuing Lender
shall be required to be returned  by the Issuing  Lender,  such L/C  Participant
shall return to the Issuing Lender the portion thereof previously distributed by
the Issuing Lender to it.

     3.5  Reimbursement  Obligation  of the  Borrower.  The  Borrower  agrees to
reimburse the Issuing Lender on each date on which the Issuing  Lender  notifies
the  Borrower  of the date and amount of a draft  presented  under any Letter of
Credit and paid by the  Issuing  Lender for the amount of (a) such draft so paid
and (b) any taxes,  fees,  charges or other  costs or  expenses  incurred by the
Issuing Lender in connection with such payment.  Each such payment shall be made
to the Issuing  Lender at its address  for  notices  specified  herein in lawful
money of the United States and in immediately available funds. Interest shall be
payable to the  Issuing  Lender on any and all amounts  drawn  under  Letters of
Credit from the date of such drawing  until the date three  Business  Days after
receipt by the Borrower from the Issuing Lender of notice of such drawing at the
rate set forth in Section  2.12(b) for Revolving  Credit Loans,  and  thereafter
until payment in full at the rate set forth in Section 2.12(c).

     3.6 Obligations Absolute.  The Borrower's  obligations under this Section 3
shall  be  absolute  and  unconditional  under  any  and all  circumstances  and
irrespective  of any  setoff,  counterclaim  or  defense  to  payment  which the
Borrower may have or have had against the Issuing  Lender,  any beneficiary of a
Letter of Credit or any other Person.  The Borrower also agrees with the Issuing
Lender that, subject to Section 3.7, the Issuing Lender shall not be responsible
for, and the Borrower's Reimbursement Obligations under Section 3.5 shall not be
affected by, among other things,  the validity or genuineness of documents or of
any endorsements  thereon,  even though such documents shall in fact prove to be
invalid,  fraudulent or forged, or any dispute between or among the Borrower and
any  beneficiary of any Letter of Credit or any other party to which such Letter
of Credit may be  transferred or any claims  whatsoever of the Borrower  against
any  beneficiary  of such Letter of Credit or any such  transferee.  The Issuing
Lender  shall not be liable for any error,  omission,  interruption  or delay in
transmission,   dispatch  or   delivery  of  any  message  or  advice,   however
transmitted,  in  connection  with any  Letter of  Credit,  except for errors or
omissions  found by a final and  nonappealable  decision of a court of competent
jurisdiction to have resulted from the gross negligence or willful misconduct of
the Issuing Lender.  The Borrower agrees that any action taken or omitted by the
Issuing  Lender under or in connection  with any Letter of Credit or the related
drafts or  documents,  if done in the  absence  of gross  negligence  or willful
misconduct and in accordance with the standards of care specified in the Uniform
Commercial  Code of the State of New York,  shall be binding on the Borrower and
shall not result in any liability of the Issuing Lender to the Borrower.

     3.7 Letter of Credit Payments.  If any draft shall be presented for payment
under any  Letter of  Credit,  the  Issuing  Lender  shall  promptly  notify the
Borrower  of the date and amount  thereof.  The  responsibility  of the  Issuing
Lender to the Borrower in connection  with any draft presented for payment under
any Letter of Credit  shall,  in addition to any  payment  obligation  expressly
provided  for in such Letter of Credit,  be to determine  whether the  documents
(including each draft)  delivered under such Letter of Credit in connection with
such presentment are substantially in conformity with such Letter of Credit.

     3.8  Applications.  To the extent  that any  provision  of any  Application
related  to any Letter of Credit is  inconsistent  with the  provisions  of this
Section 3, the provisions of this Section 3 shall apply.


                    SECTION 4. REPRESENTATIONS AND WARRANTIES

     To induce the Arranger,  the Administrative Agent, the Collateral Agent and
the  Lenders  to enter  into this  Agreement  and to make the Loans and issue or
participate  in the  Letters of  Credit,  the  Borrower  hereby  represents  and
warrants to the Arranger,  the  Administrative  Agent,  the Collateral Agent and
each  Lender  that:  4.1  Financial  Condition.  (a)  The  unaudited  pro  forma
consolidated  balance  sheet of the Borrower as at December 31, 1996  (including
the notes  thereto)  (the  "Pro  Forma  Balance  Sheet"),  copies of which  have
heretofore been furnished to each Lender, has been prepared giving effect (as if
such events had occurred on such date) to the  borrowings  under this  Agreement
contemplated to be made on the Closing Date and the use of proceeds  thereof and
the payment of estimated  fees and  expenses in  connection  therewith.  The Pro
Forma Balance Sheet has been prepared based on the best information available to
the  Borrower as of the date of  delivery  thereof  and  presents  fairly in all
material  respects on a pro forma  basis the  estimated  consolidated  financial
position  of the  Borrower as of  December 31,  1996,  assuming  that the events
specified in the preceding sentence had actually occurred at such date.

     (b) The audited  consolidated balance sheets of the Borrower as at June 30,
1996 and June 30, 1995 and the related audited consolidated statements of income
and of cash flows for the fiscal years ended on such dates,  reported on by KPMG
Peat Marwick LLP, copies of which have heretofore been furnished to each Lender,
are  complete  and correct  and  present  fairly in all  material  respects  the
consolidated  financial  condition  of the  Borrower as at such  dates,  and the
consolidated  results of operations and  consolidated  cash flows for the fiscal
years then ended. The unaudited consolidated balance sheet of the Borrower as at
March 31, 1997, and the related unaudited consolidated  statements of income and
of cash  flows for the  nine-month  period  ended on such date,  certified  by a
Responsible  Officer  of the  Borrower,  copies of which  have  heretofore  been
furnished  to each Lender,  are  complete and correct and present  fairly in all
material  respects the  consolidated  financial  condition of the Borrower as at
such date,  and the  consolidated  results of operations and  consolidated  cash
flows for the  nine-month  period then ended  (subject to normal  year-end audit
adjustments).

     All such financial statements  described in this Section 4.1(b),  including
the related  schedules and notes thereto,  have been prepared in accordance with
GAAP applied consistently throughout the periods involved (except as approved by
such accountants and as disclosed  therein).  Except for contingent  obligations
incurred in the ordinary course of business, the Borrower had at the date of the
most recent  audited  balance  sheet  referred to above no material  undisclosed
liabilities, Guarantee Obligations, contingent liability or liability for taxes,
nor any material  long-term  lease or unusual  forward or long-term  commitment,
including,  without  limitation,  any interest rate or foreign  currency swap or
exchange  transaction,  which is not  reflected in such balance  sheet or in the
notes  thereto.  During the period from June 30, 1996 to and  including the date
hereof there has been no sale,  transfer or other disposition by the Borrower or
any of its  Consolidated  Subsidiaries of any material part of their business or
property.

     4.2 No Change.  (a) Since June 30, 1996,  there has been no  development or
event which has had or could  reasonably be expected to have a Material  Adverse
Effect,  and  (b) during the period from June 30, 1996 to and including the date
hereof no dividends or other distributions have been declared, paid or made upon
the  Capital  Stock  of the  Borrower  nor has any of the  Capital  Stock of the
Borrower been redeemed,  retired,  purchased or otherwise  acquired for value by
the Borrower.

     4.3 Corporate  Existence;  Compliance with Law. Each Loan Party (a) is duly
organized,  validly  existing  and  in  good  standing  under  the  laws  of the
jurisdiction of its  organization,  except (in the case of any Subsidiary) where
the failure to do so could not reasonably be expected to have a Material Adverse
Effect, (b) has the power and authority, and the legal right, to own and operate
its  property,  to lease the  property  it operates as lessee and to conduct the
business in which it is  currently  engaged,  except  where the failure to do so
could not reasonably be expected to have a Material Adverse Effect,  (c) is duly
qualified and in good  standing  under the laws of each  jurisdiction  where its
ownership,  lease or  operation  of  property  or the  conduct  of its  business
requires such  qualification,  except where the failure to be so qualified could
not  reasonably  be  expected  to have a Material  Adverse  Effect and (d) is in
compliance with all Requirements of Law except to the extent that the failure to
comply  therewith could not, in the aggregate,  reasonably be expected to have a
Material Adverse Effect.

     4.4 Corporate  Power;  Authorization;  Enforceable  Obligations.  Each Loan
Party has the power and  authority,  and the legal right,  to make,  deliver and
perform  each  Loan  Document  to  which it is a party  and,  in the case of the
Borrower, to borrow hereunder. Each Loan Party has taken all necessary action to
authorize the execution, delivery and performance of the Loan Documents to which
it is a party and, in the case of the Borrower,  to authorize the  borrowings on
the terms and conditions of this Agreement and the Notes. No material consent or
authorization  of, filing with,  notice to or other act by or in respect of, any
Governmental  Authority or any other Person is required in  connection  with the
transactions   contemplated   hereby,  the  borrowings  hereunder  or  with  the
execution, delivery,  performance,  validity or enforceability of this Agreement
or any of the Loan Documents, except for those obtained on or before the date of
this Agreement and listed in Schedule 4.4, and except the filings referred to in
Section 4.19.  Each Loan Document has been duly executed and delivered on behalf
of each Loan Party  thereto.  This  Agreement  constitutes,  and each other Loan
Document upon execution will constitute,  a legal,  valid and binding obligation
of each  Loan  Party  thereto,  enforceable  against  each  such  Loan  Party in
accordance with its terms, except as enforceability may be limited by applicable
bankruptcy, insolvency, reorganization, moratorium or similar laws affecting the
enforcement of creditors' rights generally and by general  equitable  principles
(whether enforcement is sought by proceedings in equity or at law).

     4.5 No Legal Bar. The execution, delivery and performance of this Agreement
and the other Loan Documents,  the issuance of Letters of Credit, the borrowings
hereunder and the use of the proceeds  thereof will not violate any  Requirement
of Law or  Contractual  Obligation  of any Loan Party and will not result in, or
require,  the  creation  or  imposition  of any Lien on any of their  respective
properties or revenues  pursuant to any such  Requirement  of Law or Contractual
Obligation (other than the Liens created by the Security Documents).

     4.6 No Material Litigation.  No litigation,  investigation or proceeding of
or before  any  arbitrator  or  Governmental  Authority  is  pending  or, to the
knowledge of the  Borrower,  threatened by or against the Borrower or any of its
Subsidiaries  or against any of its or their  respective  properties or revenues
(a)  with  respect  to any  of the  Loan  Documents  or any of the  transactions
contemplated hereby or thereby or (b) which could reasonably be expected to have
a Material Adverse Effect.

     4.7 No Default.  Neither the  Borrower  nor any of its  Subsidiaries  is in
default  under or with  respect  to any of its  Contractual  Obligations  in any
respect which could reasonably be expected to have a Material Adverse Effect. No
Default or Event of Default has occurred and is continuing.

     4.8  Ownership  of Property;  Liens.  Each of the Borrower and its Domestic
Subsidiaries  has title in fee simple to, or a valid leasehold  interest in, all
its real property,  and good title to, or a valid leasehold interest in, all its
other  property,  and none of such  property  is subject  to any Lien  except as
permitted  by  Section  7.3.  The  Borrower  and its  Subsidiaries  (other  than
Servicios)  have no fee interests in any material  real property  other than the
Mortgaged  Property,  the Oil and Gas Properties and, as of the date hereof, the
real property described on Schedule 4.8.

     4.9 Intellectual  Property. The Borrower and each of its Subsidiaries owns,
or is licensed  to use,  all  trademarks,  tradenames,  copyrights,  technology,
know-how and  processes  necessary  for the conduct of its business as currently
conducted,  except  for those the  failure  to own or  license  which  could not
reasonably  be expected to have a Material  Adverse  Effect  (collectively,  the
"Intellectual  Property"). No material claim has been asserted and is pending by
any Person  challenging or questioning the use of any  Intellectual  Property or
the  validity  or  effectiveness  of any  Intellectual  Property,  nor  does the
Borrower  know  of any  valid  basis  for  any  such  claim.  To the  Borrower's
knowledge, the use of Intellectual Property by the Borrower and its Subsidiaries
does not  infringe  on the rights of any Person  where such  infringement  could
reasonably be expected to have a Material Adverse Effect.

     4.10 No  Burdensome  Restrictions.  No  Requirement  of Law or  Contractual
Obligation  of the  Borrower  or any of its  Subsidiaries  could  reasonably  be
expected to have a Material Adverse Effect.

     4.11 Taxes. Each of the Borrower and its Domestic Subsidiaries,  and to the
knowledge  of the  Borrower,  Servicios  has  filed or  caused  to be filed  all
material Federal, state and other tax returns which are required to be filed and
has paid  all  taxes  shown  to be due and  payable  on said  returns  or on any
assessments made against it or any of its property and all other taxes,  fees or
other charges imposed on it or any of its property by any Governmental Authority
(other than any the amount or validity of which are currently being contested in
good faith by  appropriate  proceedings  and with  respect to which  reserves in
conformity  with GAAP  have been  provided  on the  books of the  Borrower);  no
material  tax Lien has been filed;  and, to the  knowledge of the  Borrower,  no
claim is being asserted, with respect to any material tax, fee or other charge.

     4.12 Federal Regulations. Except as otherwise provided by Sections 4.16 and
7.7,  no part of the  proceeds  of any Loans  will be used for  "purchasing"  or
"carrying"  any "margin  stock"  within the  respective  meanings of each of the
quoted  terms under  Regulation  G or  Regulation U of the Board as now and from
time to time  hereafter in effect.  No part of the proceeds of any Loans will be
used for any purpose which  violates the  provisions of the  Regulations  of the
Board. If requested by any Lender or the Administrative Agent, the Borrower will
furnish to the Administrative Agent and each Lender a statement to the foregoing
effect  in  conformity  with  the  requirements  of FR Form  G-3 or FR Form  U-1
referred to in said Regulation G or Regulation U, as the case may be.

     4.13  ERISA.  Neither  a  Reportable  Event  nor  an  "accumulated  funding
deficiency"  (within  the meaning of  Section 412  of the Code or Section 302 of
ERISA) has occurred during the five-year  period prior to the date on which this
representation  is made or deemed made with  respect to any Plan,  and each Plan
has complied in all material  respects with the  applicable  provisions of ERISA
and the Code. No termination of a Single Employer Plan has occurred, and no Lien
in favor of the PBGC or a Plan has arisen,  during such five- year  period.  The
present value of all accrued  benefits under each Single Employer Plan (based on
those  assumptions  used to fund  such  Plans)  did not,  as of the last  annual
valuation date prior to the date on which this  representation is made or deemed
made,  exceed the value of the  assets of such Plan  allocable  to such  accrued
benefits by a material amount.  Neither the Borrower nor any Commonly Controlled
Entity has had a complete  or partial  withdrawal  from any  Multiemployer  Plan
which has  resulted  or could  reasonably  be  expected  to result in a material
liability  under ERISA,  and neither the  Borrower  nor any Commonly  Controlled
Entity  would  become  subject  to any  material  liability  under  ERISA if the
Borrower or any such Commonly Controlled Entity were to withdraw completely from
all Multiemployer Plans as of the valuation date most closely preceding the date
on which this  representation  is made or deemed made.  To the  knowledge of the
Borrower and the Commonly Controlled Entities,  no such Multiemployer Plan is in
Reorganization  or Insolvent.  The present value (determined using actuarial and
other  assumptions  which are reasonable in respect of the benefits provided and
the employees  participating) of the liability of the Borrower and each Commonly
Controlled  Entity for post retirement  benefits to be provided to their current
and former  employees under Plans which are welfare benefit plans (as defined in
Section 3(1) of ERISA) does not, in the  aggregate,  exceed the assets under all
such Plans allocable to such benefits by an amount in excess of $1,000,000.

     4.14  Investment  Company  Act;  Other  Regulations.  No Loan  Party  is an
"investment  company" within the meaning of the Investment  Company Act of 1940,
as amended.  No Loan Party is subject to  regulation  under any Federal or State
statute or  regulation  (other than  Regulation X of the Board) which limits its
ability to incur Indebtedness.

     4.15  Subsidiaries.  As of the date  hereof,  the  Subsidiaries  listed  on
Schedule  4.15  constitute  all  the  direct  or  indirect  Subsidiaries  of the
Borrower, and Schedule 4.15 shows, as to each such Subsidiary,  its jurisdiction
of its incorporation, its authorized capitalization and the ownership of Capital
Stock of such Subsidiary.

     4.16 Purpose of Loans;  Limitations on Use. The proceeds of the Loans shall
be used to refinance  indebtedness of the Loan Parties under the existing credit
facilities  described on Schedule 4.16 (the "Existing Credit Facilities") and to
pay related fees and expenses,  to finance  Permitted  Acquisitions  and capital
expenditures,  to  finance  the  repurchase  from  time to time the  outstanding
Capital Stock of the Borrower to the extent  permitted by subsection 7.7 and for
general  corporate  purposes of the  Borrower  and its  Subsidiaries  (including
Excluded  Subsidiaries) in the ordinary course of business;  provided,  that the
amount of proceeds of the Loans which may be used for Permitted  Acquisitions of
oil and gas  properties  shall be  limited  to an amount  equal to the lesser of
(a) $25,000,000 and (b) 65% of the value of the oil and gas properties of Odessa
Exploration   Incorporated   (after   giving   effect  to  any  such   Permitted
Acquisition), which value shall be calculated as the present value discounted at
10% of future net revenue  relating to all proved developed  producing  reserves
and proved undeveloped reserves from such properties.  In addition,  if at least
90% of the original outstanding principal amount of the Convertible Subordinated
Debentures  shall have been  converted  into common stock of the  Borrower,  the
Borrower may use  proceeds of the Loans to  repurchase  or redeem the  remaining
outstanding Convertible Subordinated Debentures as permitted by Section 7.10.

     4.17 Environmental  Matters.  Other than exceptions to any of the following
that could not, individually or in the aggregate, reasonably be expected to give

security  interest in, all right,  title and interest of the relevant pledgor in
such Pledged Securities and other  instruments,  negotiable  documents,  chattel
paper and money and the proceeds  thereof,  as security for the  Obligations (as
defined in the Master  Guarantee and Collateral  Agreement),  in each case prior
and  superior in right to any other  Person,  except for  inchoate tax liens for
obligations to be paid in the ordinary course of business.

     (b) The Master Guarantee and Collateral Agreement is effective to create in
favor of the  Collateral  Agent,  for the  benefit  of the  Lenders,  a security
interest  which has attached  (as that term is used in Section  9-203 of the New
York  UCC) in the  Collateral  described  therein  (other  than  the  Collateral
described in Section 4.19(a)), to the extent that the Loan Parties to the Master
Guarantee and Collateral Agreement have rights in such Collateral,  and proceeds
thereof,  and when financing  statements in appropriate  form are properly filed
(with  all  required  filing  fees  being  paid)  in the  offices  specified  on
Schedule 4.19(b)  and, with respect to vehicles  included in the  Collateral and
covered by certificates of title issued by any State, when the security interest
of the  Collateral  Agent  has  been  noted  on such  certificate  of  title  in
accordance  with  the  certificate  of  title  laws of such  State,  the  Master
Guarantee and  Collateral  Agreement  shall  constitute a perfected Lien on, and
security  interest  in, all right,  title and  interest  of the Loan  Parties in
substantially all of such Collateral and the proceeds  thereof,  as security for
the Obligations (as defined in the Master  Guarantee and Collateral  Agreement),

respect to Liens expressly permitted by Section 7.3.

     (c) Each Mortgage,  when executed and delivered by the relevant Loan Party,
and properly  filed and recorded  (with all required  filing and recording  fees
being paid) in the office(s) specified on  Schedule 4.19(c),  shall constitute a
Lien on, and  security  interest  in, all right,  title and interest of the Loan
Parties in the Mortgaged Property properly  described  therein,  as security for
the  Obligations (as defined in the relevant  Mortgage),  in each case prior and
superior  in right  to any  other  Person,  other  than  with  respect  to Liens
expressly permitted by Section 7.3.

     (d) Each Oil and Gas Mortgage,  when executed and delivered by the relevant
Loan Party,  and  properly  filed and  recorded  (with all  required  filing and
recording fees being paid) in the office(s) specified on Schedule 4.19(d), shall
constitute a perfected Lien on, and security  interest in, all right,  title and
interest  of the Loan  Parties in the Oil and Gas  Property  properly  described
therein, as security for the Obligations (as defined in the relevant Oil and Gas
Mortgage),  in each case prior and superior in right to any other Person,  other

Material Adverse Effect.  The hours worked and payments made to employees of the
Borrower  and each of its  Subsidiaries  have not been in  violation of the Fair
Labor  Standards Act or any other  applicable  Requirement of Law, except to the
extent  such  violations  could  not,  individually  or  in  the  aggregate,  be
reasonably expected to have a Material Adverse Effect. All material payments due
from the  Borrower or any of its  Subsidiaries  on account of wages and employee
health and welfare  insurance and other  benefits have been paid or accrued as a

sampling and analyzing soil, air, surface water, groundwater, and/or other media
in or about property owned or leased by the Borrower,  or on which operations of
the Borrower otherwise take place).  Such  environmental  assessment shall be in
form, scope, and substance reasonably  satisfactory to the Administrative Agent.
The  Borrower  shall  cooperate  fully  in the  conduct  of  such  environmental
assessment, and shall pay the costs of such environmental assessment immediately
upon  written  demand by the  Administrative  Agent.  Pursuant  to this  section
6.8(e),  the  Administrative  Agent shall have the right, but shall not have any

or $2,500,000 while this Agreement is in effect;

than the Borrower) unless such transaction (a) is otherwise permitted under this
Agreement,  and (b) is upon fair and  reasonable  terms no less favorable to the

approved by a majority of the  disinterested  members of the Borrower's Board of

funds have been or are to be  advanced  by such  Person on the  security of such
property or rental  obligations  of the Borrower or such  Subsidiary,  if, after
giving  effect  thereto,   the  amount  of  all  indebtedness   attributable  to
transactions  consummated  pursuant  to this  Section  7.12,  plus the amount of
Indebtedness  outstanding  pursuant to clause (c),  (f) and (i) of Section  7.2,
would exceed $15,000,000.

     7.13  Limitation  on Changes in Fiscal Year.  Permit the fiscal year of the

such  Indebtedness   constituting  a  Guarantee   Obligation  or  Interest  Rate
Protection  Agreement  Obligation) to become  payable;  provided that a default,
event or condition  described in clause (i), (ii) or (iii) of this paragraph (e)
shall  not at any time  constitute  an Event of  Default  under  this  Agreement
unless,  at such time,  one or more  defaults,  events or conditions of the type

assets, or the Borrower or any of its Subsidiaries  (other than Servicios) shall
make a general assignment for the benefit of its creditors;  or (ii) there shall
be  commenced  against  the  Borrower  or any of its  Subsidiaries  (other  than

the entry thereof;  or (iv) the Borrower or any of its Subsidiaries  (other than
Servicios)  shall take any action in  furtherance  of, or indicating its consent

in Section 406 of ERISA or  Section 4975  of the Code)  involving any Plan, (ii)
any  "accumulated  funding  deficiency"  (as  defined in Section  302 of ERISA),
whether or not waived, shall exist with respect to any Plan or any Lien in favor
of the  PBGC or a Plan  shall  arise  on the  assets  of any  Loan  Party or any
Commonly  Controlled  Entity,  (iii) a Reportable Event shall occur with respect
to, or  proceedings  shall  commence to have a trustee  appointed,  or a trustee
shall be appointed,  to administer or to terminate,  any Single  Employer  Plan,
which  Reportable  Event or  commencement  of  proceedings  or  appointment of a

and in each case in clauses (i) through  (vi)  above,  such event or  condition,

     (j) Any Change of Control shall occur;

     then,  and in any such  event,  (A) if such  event  is an Event of  Default
specified  in clause  (i) or (ii) of  paragraph  (f) above  with  respect to the
Borrower,  automatically  the Commitments  shall  immediately  terminate and the
Loans  hereunder  (with  accrued  interest  thereon) and all other amounts owing
under  this  Agreement  and  the  other  Loan  Documents   (including,   without
limitation, all amounts of L/C Obligations,  whether or not the beneficiaries of
the then  outstanding  Letters of Credit  shall  have  presented  the  documents
required  thereunder) shall immediately become due and payable,  and (B) if such
event is any other Event of Default, either or both of the following actions may
be taken: (i) with the consent of the Required Lenders, the Administrative Agent
may, or upon the  request of the  Required  Lenders,  the  Administrative  Agent
shall,  by notice to the  Borrower  declare  the  Commitments  to be  terminated
forthwith,  whereupon the Commitments shall immediately terminate; and (ii) with
the consent of the Required Lenders,  the Administrative  Agent may, or upon the
request of the Required Lenders,  the  Administrative  Agent shall, by notice to
the Borrower,  declare the Loans hereunder (with accrued  interest  thereon) and
all other  amounts  owing  under this  Agreement  and the other  Loan  Documents
(including,  without limitation, all amounts of L/C Obligations,  whether or not
the beneficiaries of the then outstanding Letters of Credit shall have presented
the documents required  thereunder) to be due and payable  forthwith,  whereupon
the same shall immediately become due and payable.

     With respect to all Letters of Credit with respect to which presentment for
honor shall not have  occurred at the time of an  acceleration  pursuant to this
paragraph,  the Borrower shall at such time deposit in a cash collateral account
opened by the Administrative Agent an amount equal to the aggregate then undrawn
and  unexpired  amount of such  Letters  of  Credit.  Amounts  held in such cash
collateral account shall be applied by the  Administrative  Agent to the payment
of drafts drawn under such  Letters of Credit,  and the unused  portion  thereof
after all such Letters of Credit shall have expired or been fully drawn upon, if
any, shall be applied to repay other  obligations of the Borrower  hereunder and
under the other Loan  Documents.  After all such  Letters  of Credit  shall have
expired or been fully drawn upon, all Reimbursement  Obligations shall have been
satisfied  and all other  obligations  of the Borrower  hereunder  and under the
other Loan Documents shall have been paid in full, the balance,  if any, in such
cash collateral  account shall be returned to the Borrower (or such other Person
as may be lawfully entitled thereto). Except as expressly provided above in this
Section,  presentment,  demand,  protest  and all other  notices of any kind are
hereby expressly waived.

                              SECTION 9. THE AGENTS

     9.1 Appointment. Each Lender hereby irrevocably designates and appoints the
Agents as the  agents of such  Lender  under this  Agreement  and the other Loan
Documents,  and each Lender irrevocably authorizes each Agent, in such capacity,
to take such action on its behalf under the provisions of this Agreement and the
other Loan  Documents and to exercise such powers and perform such duties as are
expressly  delegated to such Agent by the terms of this  Agreement and the other
Loan  Documents,  together with such other powers as are  reasonably  incidental
thereto.  Notwithstanding  any  provision  to the  contrary  elsewhere  in  this
Agreement,  no Agent  shall have any duties or  responsibilities,  except  those
expressly set forth herein, or any fiduciary  relationship with any Lender,  and
no  implied  covenants,  functions,  responsibilities,  duties,  obligations  or
liabilities  shall be read into this  Agreement  or any other Loan  Document  or
otherwise exist against any Agent.

     9.2  Delegation  of Duties.  Each Agent may execute any of its duties under
this   Agreement  and  the  other  Loan   Documents  by  or  through  agents  or
attorneys-in-fact  and shall be  entitled  to advice of counsel  concerning  all
matters  pertaining  to such  duties.  No  Agent  shall be  responsible  for the
negligence or misconduct of any agents or attorneys  in-fact selected by it with
reasonable care.

     9.3 Exculpatory  Provisions.  Neither the Agents nor any of their officers,
directors,  employees,  agents,  attorneys-in-fact  or  Affiliates  shall be (i)
liable for any action lawfully taken or omitted to be taken by it or such Person
under or in connection with this Agreement or any other Loan Document (except to
the  extent  that any of the  foregoing  are found by a final and  nonappealable
decision of a court of competent  jurisdiction to have resulted from its or such
Person's own gross negligence or willful  misconduct) or (ii) responsible in any
manner to any of the Lenders for any recitals,  statements,  representations  or
warranties  made by any Loan  Party or any  officer  thereof  contained  in this
Agreement or any other Loan Document or in any certificate, report, statement or
other document referred to or provided for in, or received by any Agent under or
in connection  with, this Agreement or any other Loan Document or for the value,
validity,  effectiveness,  genuineness,  enforceability  or  sufficiency of this
Agreement or the Notes or any other Loan Document or for any failure of any Loan
Party a party thereto to perform its  obligations  hereunder or  thereunder.  No
Agent shall be under any  obligation to any Lender to ascertain or to inquire as
to the  observance  or  performance  of any of the  agreements  contained in, or
conditions  of, this  Agreement  or any other Loan  Document,  or to inspect the
properties, books or records of any Loan Party.

     9.4 Reliance by Agents.  Each Agent shall be entitled to rely, and shall be
fully protected in relying, upon any Note, writing, resolution, notice, consent,
certificate,  affidavit, letter, telecopy, telex or teletype message, statement,
order or other document or conversation believed by it to be genuine and correct
and to have been signed,  sent or made by the proper  Person or Persons and upon
advice and statements of legal counsel (including,  without limitation,  counsel
to the Borrower),  independent  accountants  and other experts  selected by such
Agent.  The Agents may deem and treat the payee of any Note as the owner thereof
for all purposes unless a written notice of assignment,  negotiation or transfer
thereof shall have been filed with the Administrative Agent. Each Agent shall be
fully  justified in failing or refusing to take any action under this  Agreement
or any  other  Loan  Document  unless  it shall  first  receive  such  advice or
concurrence of the Required Lenders (or, if so specified by this Agreement,  all
Lenders)  as it deems  appropriate  or it  shall  first  be  indemnified  to its
satisfaction  by the Lenders against any and all liability and expense which may
be incurred  by it by reason of taking or  continuing  to take any such  action,
provided that in no event shall the Lenders be obligated to indemnify the Agents
for any amounts described in the proviso to Section 9.7. Each Agent shall in all
cases be fully  protected in acting,  or in refraining  from acting,  under this
Agreement  and the other  Loan  Documents  in  accordance  with a request of the
Required Lenders (or, if so specified by this Agreement,  all Lenders), and such
request and any action taken or failure to act pursuant thereto shall be binding
upon all the Lenders and all future holders of the Notes.

     9.5 Notice of Default. No Agent shall be deemed to have knowledge or notice
of the occurrence of any Default or Event of Default hereunder unless such Agent
has  received  written  notice from a Lender or the  Borrower  referring to this
Agreement,  describing  such  Default or Event of Default and stating  that such
notice is a "notice  of  default".  In the event that the  Administrative  Agent
receives such a notice,  the  Administrative  Agent shall give notice thereof to
the Lenders.  The Administrative  Agent and the Collateral Agent shall take such
action with respect to such  Default or Event of Default as shall be  reasonably
directed by the Required  Lenders (or, if so  specified by this  Agreement,  all
Lenders);  provided  that  unless  and  until  the  Administrative  Agent or the
Collateral Agent shall have received such directions,  the Administrative  Agent
or the Collateral Agent may (but shall not be obligated to) take such action, or
refrain  from  taking  such  action,  with  respect to such  Default or Event of
Default as it shall deem advisable in the best interests of the Lenders.

     9.6  Non-Reliance  on  Agents  and Other  Lenders.  Each  Lender  expressly
acknowledges  that  neither  any  Agent  nor  any  of its  officers,  directors,
employees, agents,  attorneys-in-fact or Affiliates has made any representations
or warranties to it and that no act by the Agents hereafter taken, including any
review of the affairs of a Loan Party or any Affiliate of a Loan Party, shall be
deemed to constitute any  representation or warranty by any Agent to any Lender.
Each  Lender  represents  to each Agent that it has,  independently  and without
reliance  upon any Agent or any other  Lender,  and based on such  documents and
information  as it  has  deemed  appropriate,  made  its  own  appraisal  of and
investigation  into the  business,  operations,  property,  financial  and other
condition and creditworthiness of the Loan Parties and their Affiliates and made
its own decision to make its Loans hereunder and enter into this Agreement. Each
Lender also represents that it will, independently and without reliance upon any
Agent or any other Lender,  and based on such  documents and  information  as it
shall deem  appropriate at the time,  continue to make its own credit  analysis,
appraisals and decisions in taking or not taking action under this Agreement and
the other Loan Documents,  and to make such  investigation as it deems necessary
to inform itself as to the business,  operations,  property, financial and other
condition and creditworthiness of the Loan Parties and their Affiliates.  Except
for notices,  reports and other documents  expressly required to be furnished to
the Lenders by the Administrative Agent hereunder,  no Agent shall have any duty
or  responsibility  to provide any Lender  with any credit or other  information
concerning  the  business,   operations,   property,   condition  (financial  or
otherwise),  prospects or creditworthiness of any Loan Party or any Affiliate of
a Loan  Party  which may come into the  possession  of such  Agent or any of its
officers, directors, employees, agents, attorneys-in-fact or Affiliates.

     9.7  Indemnification.  The  Lenders  agree to  indemnify  each Agent in its
capacity  as such (to the extent not  reimbursed  by the  Borrower  and  without
limiting the  obligation of the Borrower to do so),  ratably  according to their
respective Commitments,  from and against any and all liabilities,  obligations,
losses,  damages,  penalties,  actions,  judgments,  suits,  costs,  expenses or
disbursements of any kind whatsoever  which may at any time (including,  without
limitation,  at any time  following  the  payment of the  Notes) be imposed  on,
incurred by or asserted  against any Agent in any way relating to or arising out
of, the  Commitments,  this  Agreement,  any of the other Loan  Documents or any
documents  contemplated by or referred to herein or therein or the  transactions
contemplated hereby or thereby or any action taken or omitted by any Agent under
or in  connection  with any of the  foregoing;  provided that no Lender shall be
liable for the payment of any portion of such liabilities,  obligations, losses,
damages, penalties,  actions, judgments, suits, costs, expenses or disbursements
which are found by a final and  nonappealable  decision of a court of  competent
jurisdiction  to have  resulted  from such Agent's  gross  negligence or willful
misconduct.  The agreements in this Section 9.7 shall survive the payment of the
Notes and all other amounts payable hereunder.

     9.8 Agents in Their  Individual  Capacities.  Each Agent and its Affiliates
may make loans to,  accept  deposits  from and  generally  engage in any kind of
business  with any Loan Party as though  such Agent were not an Agent  hereunder
and under the other Loan Documents. With respect to its Loans made or renewed by
it and any Note issued to it and with respect to any Letter of Credit  issued or
participated  in by it, each Agent  shall have the same rights and powers  under
this  Agreement and the other Loan  Documents as any Lender and may exercise the
same as though it were not an Agent,  respectively,  and the terms  "Lender" and
"Lenders" shall include each Agent in their individual capacities.

     9.9 Successor Agents. The Administrative  Agent or the Collateral Agent may
resign as Administrative  Agent or Collateral Agent, as the case may be, upon 10
days' notice to the Lenders. If the Administrative Agent or the Collateral Agent
shall resign as  Administrative  Agent or Collateral  Agent under this Agreement
and the other Loan Documents, then the Required Lenders shall appoint from among
the Lenders a successor agent in such capacity,  which successor  agent, so long
as no Default or Event of Default shall have occurred and be  continuing,  shall
have been approved by the Borrower  (which  approval  shall not be  unreasonably
withheld or  delayed),  whereupon  such  successor  agent  shall  succeed to the
rights,  powers and duties of the Administrative  Agent or the Collateral Agent,
as the case may be, hereunder. Effective upon such appointment and approval, the
terms  "Administrative  Agent" and "Collateral  Agent" shall mean such successor
agent,  and the former  Administrative  Agent's or  Collateral  Agent's  rights,
powers and duties as such shall be terminated,  without any other or further act
or deed on the part of such former  Administrative  Agent or Collateral Agent or
any of the  parties to this  Agreement  or any  holders of the Notes.  After any
retiring  Agent's  resignation as Agent,  the provisions of this Section 9 shall
inure to its benefit as to any actions  taken or omitted to be taken by it while
it was Agent under this Agreement and the other Loan Documents.

                            SECTION 10. MISCELLANEOUS

     10.1  Amendments  and  Waivers.  Neither  this  Agreement,  any other  Loan
Document,  nor any terms  hereof or  thereof  may be  amended,  supplemented  or

assignment  or transfer  by any Loan Party of any of its rights and  obligations
under  this  Agreement  and  the  other  Loan  Documents  or  release  all  or a
substantial portion of the Collateral (other than in connection with any sale or
other  disposition  of assets  permitted by Section 7.6) or any guarantee of the
Obligations,  in each case, without the written consent of all the Lenders,  (v)
amend, modify or waive any provision of Section 9 without the written consent of
the Agents,  or (vi) amend,  modify or waive any  provision of Section 3 without
the  written  consent  of the  Issuing  Lender.  Any  such  waiver  and any such
amendment, supplement or modification shall apply equally to each of the Lenders
and shall be binding  upon the Loan  Parties,  the  Lenders,  the Agents and all
future holders of the Notes.  In the case of any waiver,  the Loan Parties,  the
Lenders and the Agents  shall be restored to their  former  position  and rights
hereunder  and under the  other  Loan  Documents,  and any  Default  or Event of
Default  waived  shall be  deemed to be cured  and not  continuing;  but no such
waiver shall extend to any  subsequent  or other  Default or Event of Default or
impair any right consequent thereon.

     provided that any notice,  request or demand to or upon the  Administrative
Agent or the Lenders pursuant to Section 2.2, 2.4, 2.7, 2.8 or 2.10 shall not be
effective until received.  Any notice or delivery to or from or consent required
of the Borrower  hereunder or pursuant to any other Loan Document may be made to
or by the Borrower.

     10.3 No Waiver; Cumulative Remedies. No failure to exercise and no delay in
exercising,  on the part of any Agent or any Lender, any right, remedy, power or
privilege  hereunder or under the other Loan Documents shall operate as a waiver
thereof; nor shall any single or partial exercise of any right, remedy, power or
privilege  hereunder  preclude  any other or  further  exercise  thereof  or the
exercise of any other right, remedy, power or privilege.  The rights,  remedies,
powers and  privileges  herein  provided are cumulative and not exclusive of any
rights, remedies, powers and privileges provided by law.

     10.4 Survival.  All representations  and warranties made hereunder,  in the
other Loan  Documents and in any document,  certificate  or statement  delivered
pursuant  hereto or in  connection  herewith  shall  survive the  execution  and
delivery of this Agreement and the Notes and the making of the Loans hereunder.

     10.5  Payment of  Expenses  and Taxes.  The  Borrower  agrees (a) to pay or
reimburse the Agents for all their reasonable  out-of-pocket  costs and expenses
incurred in connection with the  development,  preparation and execution of, and
any amendment,  supplement or modification to, this Agreement and the other Loan
Documents and any other documents prepared in connection  herewith or therewith,
and the consummation and administration of the transactions  contemplated hereby
and  thereby,   including,   without   limitation,   the  reasonable   fees  and
disbursements of counsel (including any local counsel) to the Agents, (b) to pay
or  reimburse  each Lender and each of the Agents for all its costs and expenses
incurred in connection  with the enforcement or preservation of any rights under
this  Agreement,  the  other  Loan  Documents  and  any  such  other  documents,
including,  without limitation, the fees and disbursements of counsel (including
the allocated fees and expenses of in-house  counsel) to each Lender and counsel
to the  Agents,  (c) to pay,  indemnify,  and hold each  Lender  and each  Agent
harmless from, any and all recording and filing fees and any and all liabilities
with respect to, or resulting from any delay in paying,  stamp, excise and other
taxes,  if any,  which may be payable or  determined to be payable in connection
with the execution and delivery of, or consummation or  administration of any of
the transactions  contemplated by, or any amendment,  supplement or modification
of, or any waiver or consent under or in respect of, this  Agreement,  the other
Loan Documents and any such other documents, and (d) to pay, indemnify, and hold
each Lender and each Agent and their respective officers,  directors,  trustees,
employees,  affiliates,  agents and controlling  persons (each, an "indemnitee")
harmless from and against any and all other  liabilities,  obligations,  losses,
damages, penalties,  actions, judgments, suits, costs, expenses or disbursements
of any kind or  nature  whatsoever  with  respect  to the  execution,  delivery,
enforcement,  performance and  administration of this Agreement,  the other Loan
Documents and any such other documents,  including,  without limitation,  any of
the foregoing  relating to the use of proceeds of the Loans or the violation of,
noncompliance  with or liability under, any  Environmental Law applicable to the
Borrower,  any of its Subsidiaries,  any of its Excluded  Subsidiaries or any of
the  Properties  (all  the  foregoing  in this  clause  (d),  collectively,  the
"indemnified liabilities"),  provided that the Borrower shall have no obligation
hereunder to any  indemnitee  with  respect to  indemnified  liabilities  to the
extent  such  indemnified  liabilities  are found by a final  and  nonappealable
decision of a court of competent  jurisdiction  to have  resulted from the gross
negligence  or willful  misconduct  of such  indemnitee.  Without  limiting  the
foregoing,  and to the extent  permitted by applicable  law, the Borrower agrees
not to assert,  and hereby waives,  and to cause each of its Subsidiaries not to
assert  and to so waive,  all  rights for  contribution  or any other  rights of
recovery with respect to all claims,  demands,  penalties,  fines,  liabilities,
settlements,  damages,  costs and expenses of whatever kind or nature,  under or
related  to  Environmental  Laws,  that any of them  might  have by  statute  or
otherwise  against any  Indemnitee.  The  agreements  in this Section 10.5 shall
survive  repayment of the Notes and all other amounts payable  hereunder and the
termination  of the  Commitments  and, in the case of any Lender that may assign
any interest in its Commitments,  Loans or Letter of Credit interest  hereunder,
shall survive the making of such assignment, notwithstanding that such assigning
Lender may cease to be a "Lender" hereunder.

     10.6  Successors  and  Assigns;  Participation  and  Assignments.  (a) This
Agreement  shall be binding upon and inure to the benefit of the  Borrower,  the
Lenders,  the  Agents,  all  future  holders  of the Notes and their  respective
successors and assigns,  except that the Borrower may not assign or transfer any
of its rights or  obligations  under this  Agreement  without the prior  written
consent of each Lender.

     (b) Any Lender may,  without the consent of the  Borrower,  in the ordinary
course of its business and in accordance  with  applicable law, at any time sell
to one or more banks or other  entities  (each, a  "Participant")  participating
interests  in any Loan owing to such Lender,  any Note held by such Lender,  any
Commitment  of such Lender or any other  interest of such Lender  hereunder  and
under the other Loan  Documents.  In the event of any such sale by a Lender of a
participating  interest to a Participant,  such Lender's  obligations under this
Agreement to the other parties to this Agreement  shall remain  unchanged,  such
Lender shall remain solely responsible for the performance thereof,  such Lender
shall remain the holder of any such Note for all purposes  under this  Agreement
and the other Loan  Documents,  and the  Borrower and the  Administrative  Agent
shall  continue to deal solely and directly with such Lender in connection  with
such Lender's  rights and  obligations  under this  Agreement and the other Loan
Documents.  In no event shall any Participant under any such  participation have
any right to  approve  any  amendment  or waiver  of any  provision  of any Loan
Document, or any consent to any departure by any Loan Party therefrom, except to
the extent that such amendment, waiver or consent would reduce the principal of,
or interest  on, the Notes or any fees payable  hereunder,  postpone the date of
the final  maturity of the Notes,  consent to the  assignment or transfer by the
Borrower of any of its rights and obligations under this Agreement and the other
Loan Documents,  release all or a substantial  portion of the Collateral  (other
than in connection  with any sale or other  disposition  of assets  permitted by
Section  7.6) or any  guarantee of the  Obligations,  in each case to the extent
subject to such  participation.  The Borrower agrees that if amounts outstanding
under  this  Agreement  and the  Notes  are due or  unpaid,  or shall  have been
declared or shall have become due and payable upon the occurrence of an Event of
Default,  each Participant  shall, to the maximum extent permitted by applicable
law,  be deemed to have the right of  setoff  in  respect  of its  participating
interest in amounts  owing under this  Agreement and any Note to the same extent
as if the amount of its  participating  interest were owing  directly to it as a
Lender under this  Agreement or any Note,  provided  that,  in  purchasing  such
participating interest, such Participant shall be deemed to have agreed to share
with the Lenders the proceeds thereof as provided in Section 10.7(a) as fully as
if it were a Lender  hereunder.  The Borrower also agrees that each  Participant
shall be entitled to the benefits of Sections  2.17,  2.18 and 2.19 with respect
to its  participation in the Commitments and the Loans  outstanding from time to
time as if it was a Lender;  provided  that, in the case of Section  2.18,  such
Participant  shall have  complied  with the  requirements  of said  Section  and
provided,  further, that no Participant shall be entitled to receive any greater
amount  pursuant to any such Section than the transferor  Lender would have been
entitled to receive in respect of the amount of the participation transferred by
such transferor Lender to such Participant had no such transfer occurred.

     (c)  Any  Lender  may,  in  the  ordinary  course  of its  business  and in
accordance  with applicable law, at any time and from time to time assign to any
Lender or any affiliate  thereof or any Person under common  management with any
such Lender or, with the consent of the Borrower,  the Administrative Agent, the
Arranger and, in the case of an assignment of Revolving Credit Commitments,  the
Issuing Lender (which, in each case, shall not be unreasonably withheld, delayed
or conditioned)  (provided that no such consent need be obtained by the Arranger
for a period of 120 days  following the Closing  Date),  to an additional  bank,
financial  institution  or other entity (an  "Assignee")  all or any part of its
rights and obligations under this Agreement, the Letters of Credit and the Notes
pursuant to an Assignment and Acceptance,  substantially  in the form of Exhibit
G,  executed by such  Assignee,  such  assigning  Lender (and, in the case of an
Assignee  that is not then a Lender or an  affiliate  thereof or a Person  under
common management with such Lender, by the Borrower,  the Administrative  Agent,
the Arranger and, in the case of an assignment of Revolving Credit  Commitments,
the Issuing Lender) and delivered to the Administrative Agent for its acceptance
and recording in the Register with a copy to the Arranger; provided that (except
with the consent of the Borrower, the Administrative Agent and the Arranger) (i)
no such  assignment  to an  Assignee  (other  than any  Lender or any  affiliate
thereof or any Person under common  management  with such Lender) shall be in an
aggregate principal amount of less than $5,000,000 (other than in the case of an
assignment of all of a Lender's  interests  under this  Agreement and the Notes)
and (ii) subsequent to any such assignment the assigning Lender shall not retain
an aggregate  principal amount of less than $5,000,000 in Commitments and Loans.
Such  assignment need not be ratable as among any Term Loan  Commitments  and/or
Term Loans and Revolving Credit Commitments and/or Revolving Credit Loans of the
assigning Lender. Upon such execution,  delivery, acceptance and recording, from
and  after  the  effective  date  determined  pursuant  to such  Assignment  and
Acceptance,  (x) the  Assignee  thereunder  shall be a party  hereto and, to the
extent  provided  in  such  Assignment  and  Acceptance,  have  the  rights  and
obligations of a Lender  hereunder  with a Commitment as set forth therein,  and
(y) the  assigning  Lender  thereunder  shall,  to the extent  provided  in such
Assignment and Acceptance, be released from its obligations under this Agreement
(and, in the case of an Assignment and Acceptance  covering all or the remaining
portion of an assigning  Lender's rights and  obligations  under this Agreement,
such  assigning  Lender shall cease to be a party hereto).  Notwithstanding  any
provision of this  paragraph (c) and  paragraph  (e) of this Section  10.6,  the
consent of the Borrower shall not be required for any assignment which occurs at
any time when any Event of Default shall have occurred and be continuing.

     (d) A Note and the  Obligation(s)  evidenced  thereby  may be  assigned  or
otherwise  transferred  in  whole  or in  part  only  by  registration  of  such
assignment or transfer of such Note and the  Obligation(s)  evidenced thereby on
the  Register  (and each Note shall  expressly so provide).  Any  assignment  or
transfer of all or part of such  Obligation(s)  and the Note(s)  evidencing  the
same shall be registered on the Register only upon surrender for registration of
assignment or transfer of the Note(s) evidencing such Obligation(s), accompanied
by an Assignment and Acceptance duly executed by the holder of such Note(s), and
thereupon one or more new Note(s) in the same aggregate  principal  amount shall
be issued to the designated  Assignee(s)  and the old Notes(s) shall be returned
by the Administrative Agent to the Borrower marked "cancelled." No assignment of
a Note and the Obligation(s)  evidenced thereby shall be effective unless it has
been recorded in the Register as provided in this Section 10.6(d).

     (e) The  Administrative  Agent shall maintain at its address referred to in
Section  10.2 a copy of each  Assignment  and  Acceptance  delivered to it and a
register (the  "Register") for the recordation of the names and addresses of the
Lenders and the Commitment of, and principal  amount of the Loans owing to, each
Lender  from  time  to time  and  the  registered  owners  of the  Obligation(s)
evidenced by the Note(s).  The entries in the Register shall be  conclusive,  in
the absence of manifest error, and the Borrower,  the  Administrative  Agent and
the Lenders  shall treat each Person  whose name is recorded in the  Register as
the owner of the Loan or the Obligation evidenced by a Note recorded therein for
all purposes of this  Agreement.  The Register shall be available for inspection
by the Borrower or any Lender at any reasonable  time and from time to time upon
reasonable prior notice.

     (f) Upon  its  receipt  of an  Assignment  and  Acceptance  executed  by an
assigning  Lender and an Assignee  (and,  in the case of an Assignee that is not
then a Lender or an affiliate  thereof or a Person under common  management with
such Lender,  by the Borrower,  the  Administrative  Agent, the Arranger and the
Issuing  Lender)  together  with  payment  to  the  Administrative  Agent  of  a
registration and processing fee of $2,000 (except that no such  registration and
processing  fee shall be payable (y) in connection  with an assignment by Lehman
or (z) in the case of an Assignee  which is already a Lender or is an  affiliate
of  a  Lender  or  a  Person  under  common  management  with  a  Lender),   the
Administrative  Agent shall (i) promptly  accept such  Assignment and Acceptance
and  (ii)  on  the  effective  date  determined   pursuant  thereto  record  the
information contained therein in the Register and give notice of such acceptance
and  recordation to the Lenders and the Borrower.  On or prior to such effective
date, the Borrower, at its own expense, upon request,  shall execute and deliver
to the  Administrative  Agent (in exchange for the Revolving  Credit Note and/or
Term Note, as the case may be, of the assigning  Lender) a new Revolving  Credit
Note and/or Term Note,  as the case may be, to the order of such  Assignee in an
amount equal to the Revolving  Credit  Commitment  and/or Term Loan, as the case
may be, assumed by it pursuant to such  Assignment  and  Acceptance  and, if the
assigning Lender has retained a Revolving Credit Commitment and/or Term Loan, as
the case may be, upon request,  a new Revolving Credit Note and/or Term Note, as
the case may be, to the order of the assigning  Lender in an amount equal to the
Revolving Credit Commitment and/or Term Loan, as the case may be, retained by it
hereunder. Such new Notes shall be dated the Closing Date and shall otherwise be
in the form of the Note replaced thereby.

     (g) The Borrower  authorizes  each Lender to disclose to any Participant or
Assignee  (each,  a  "Transferee")  and any  prospective  Transferee any and all
financial  information in such Lender's  possession  concerning the Borrower and
its  Affiliates  which has been  delivered to such Lender by or on behalf of the
Borrower  pursuant to this  Agreement or which has been delivered to such Lender
by or on  behalf  of the  Borrower  in  connection  with  such  Lender's  credit
evaluation of the Borrower and its Affiliates  prior to becoming a party to this
Agreement.  (h) Nothing  herein  shall  prohibit or restrict any Lender from (i)
pledging or assigning any Note to any Federal  Reserve Bank in  accordance  with
applicable  law or (ii) with the prior consent of the  Administrative  Agent and
the Borrower (which, in each case, shall not be unreasonably withheld or delayed
or conditioned),  pledging its rights in connection with any Loan or Note to any
other Person.

     10.7 Adjustments;  Set-off. (a) If any Lender (a "Benefitted Lender") shall
at any time receive any payment of all or part of its Loans or the Reimbursement
Obligations  owing to it, or  interest  thereon,  or receive any  collateral  in
respect  thereof  then due and  owing to such  Lender  (whether  voluntarily  or
involuntarily,  by  set-off,  pursuant  to events or  proceedings  of the nature
referred to in Section 8(f), or  otherwise),  in a greater  proportion  than any
such payment to or collateral  received by any other Lender,  if any, in respect
of such other Lender's Loans or the Reimbursement Obligations then due and owing
to such other Lender, or interest thereon, such Benefitted Lender shall purchase
for cash  from the other  Lenders a  participating  (or,  at the  option of such
Lender,  a direct)  interest in such  portion of each such other  Lender's  Loan
and/or of the  Reimbursement  Obligations  owing to each such other  Lender,  or
shall  provide such other Lenders with the benefits of any such  collateral,  or
the proceeds  thereof,  as shall be necessary to cause such Benefitted Lender to
share the excess payment or benefits of such collateral or proceeds ratably with
each of the Lenders;  provided that if all or any portion of such excess payment
or benefits is thereafter  recovered from such Benefitted Lender,  such purchase
shall be rescinded,  and the purchase price and benefits returned, to the extent
of such recovery, but without interest.

     (b) In addition to any rights and remedies of the Lenders  provided by law,
each Lender shall have the right, without prior notice to the Borrower, any such
notice  being  expressly  waived by the  Borrower  to the  extent  permitted  by
applicable  law,  upon any  amount  becoming  due and  payable  by the  Borrower
hereunder or under the Notes (whether at the stated maturity, by acceleration or
otherwise) to set off and  appropriate and apply against such amount any and all
deposits  (general or special,  time or demand,  provisional  or final),  in any
currency,  and any other credits,  indebtedness or claims,  in any currency,  in
each case  whether  direct or  indirect,  absolute  or  contingent,  matured  or
unmatured,  at any time  held or owing by such  Lender  or any  branch or agency
thereof to or for the credit or the account of the Borrower.  Each Lender agrees
promptly  to notify the  Borrower  and the  Administrative  Agent after any such
setoff and  application  made by such Lender,  provided that the failure to give
such notice shall not affect the validity of such setoff and application.

     10.8  Counterparts.  This  Agreement  may be executed by one or more of the
parties to this Agreement on any number of separate  counterparts  (including by
telecopy),  and all of said  counterparts  taken  together  shall be  deemed  to
constitute  one and the same  instrument.  A set of the copies of this Agreement
signed  by  all  the  parties   shall  be  lodged  with  the  Borrower  and  the
Administrative Agent.

     10.9  Severability.  Any provision of this Agreement which is prohibited or
unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective
to the extent of such prohibition or unenforceability  without  invalidating the
remaining provisions hereof, and any such prohibition or unenforceability in any
jurisdiction shall not invalidate or render  unenforceable such provision in any
other  jurisdiction.  10.10  Integration.  This  Agreement  and the  other  Loan
Documents represent the agreement of the Borrower, the Administrative Agent, the
Arranger and the Lenders with respect to the subject  matter  hereof,  and there
are  no  promises,   undertakings,   representations   or   warranties   by  the
Administrative  Agent,  the  Arranger or any Lender  relative to subject  matter
hereof  not  expressly  set forth or  referred  to  herein or in the other  Loan
Documents.

     10.11  GOVERNING  LAW.  THIS  AGREEMENT  AND THE NOTES AND THE  RIGHTS  AND
OBLIGATIONS  OF THE PARTIES UNDER THIS AGREEMENT AND THE NOTES SHALL BE GOVERNED
BY, AND CONSTRUED AND  INTERPRETED  IN ACCORDANCE  WITH, THE LAW OF THE STATE OF
NEW YORK.

     10.12 Submission To Jurisdiction;  Waivers. The Borrower hereby irrevocably
and unconditionally:

     (a) submits for itself and its property in any legal  action or  proceeding
relating to this  Agreement and the other Loan Documents to which it is a party,
or for recognition and  enforcement of any judgment in respect  thereof,  to the
non-exclusive  general  jurisdiction of the Courts of the State of New York, the
courts of the United States for the Southern District of New York, and appellate
courts from any thereof;

     (b)  consents  that any such  action or  proceeding  may be brought in such
courts and waives any objection  that it may now or hereafter  have to the venue
of any such  action  or  proceeding  in any such  court or that  such  action or
proceeding was brought in an inconvenient court and agrees not to plead or claim
the same;

     (c) agrees that service of process in any such action or proceeding  may be
effected  by mailing a copy  thereof by  registered  or  certified  mail (or any
substantially  similar form of mail),  postage  prepaid,  to the Borrower at its
address  set  forth in  Section  10.2 or at such  other  address  of  which  the
Administrative Agent shall have been notified pursuant thereto;

     (d) agrees that nothing  herein shall affect the right to effect service of
process in any other manner  permitted by law or shall limit the right to sue in
any other jurisdiction; and

     (e) waives,  to the maximum  extent not prohibited by law, any right it may
have to claim or recover in any legal action or  proceeding  referred to in this
Section 10.12 any special, exemplary, punitive or consequential damages.

     10.13 Acknowledgements. The Borrower hereby acknowledges that:

     (a) it has been  advised  by  counsel  in the  negotiation,  execution  and
delivery of this Agreement and the other Loan Documents;

     (b) neither any Agent nor any Lender has any fiduciary relationship with or
duty to the Borrower  arising out of or in connection with this Agreement or any
of the other  Loan  Documents,  and the  relationship  between  the  Agents  and
Lenders,  on one hand,  and the  Borrower,  on the  other  hand,  in  connection
herewith or therewith is solely that of debtor and creditor; and

     (c) no joint  venture is created  hereby or by the other Loan  Documents or
otherwise  exists by virtue of the  transactions  contemplated  hereby among the
Lenders or among the Borrower and the Lenders.

     10.14  WAIVERS OF JURY  TRIAL.  THE  BORROWER,  THE AGENTS AND THE  LENDERS
HEREBY IRREVOCABLY AND  UNCONDITIONALLY  WAIVE TRIAL BY JURY IN ANY LEGAL ACTION
OR PROCEEDING  RELATING TO THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT AND FOR ANY
COUNTERCLAIM THEREIN.

     10.15  Confidentiality.  Each of the Agents and each Lender  agrees to keep
confidential  all  non-public  information  provided  to it by  any  Loan  Party
pursuant  to  this   Agreement   that  is  designated  by  such  Loan  Party  as
confidential;  provided  that  nothing  herein  shall  prevent the Agents or any
Lender from  disclosing any such  information (a) to the Agents any other Lender
or any affiliate or investment  advisor of any Lender,  (b) to any Transferee or
prospective  Transferee  which  agrees to  comply  with the  provisions  of this
Section 10.15, (c) to the employees,  directors, agents, attorneys,  accountants
and other professional  advisors of such Lender or its affiliates,  (d) upon the
request or demand of any Governmental  Authority having  jurisdiction  over such
Agent  or such  Lender,  (e) in  response  to any  order  of any  court or other
Governmental  Authority  or  as  may  otherwise  be  required  pursuant  to  any
Requirement of Law, (f) if requested or required to do so in connection with any
litigation or similar  proceeding,  (g) which has been publicly  disclosed other
than in breach of this Section 10.15 or (h) in  connection  with the exercise of
any remedy hereunder or under any other Loan Document.

     10.16  Enforceability;  Usury.  In no event  shall  any  provision  of this
Agreement,  the  Notes,  or any other  instrument  evidencing  or  securing  the
indebtedness  of the  Borrower  hereunder  ever  obligate the Borrower to pay or
allow any Lender to collect  interest on the Notes or any other  indebtedness of
the Borrower  hereunder at a rate  greater  than the maximum  non-usurious  rate
permitted by applicable law (herein  referred to as the "Highest  Lawful Rate"),
or obligate  the  Borrower  to pay any taxes,  assessments,  charges,  insurance
premiums or other  amounts to the extent that such  payments,  when added to the
interest  payable on the Notes,  would be held to constitute  the payment by the
Borrower of interest at a rate  greater than the Highest  Lawful Rate;  and this
provision shall control over any provision to the contrary.

     Without limiting the generality of the foregoing, in the event the maturity
of all or any part of the principal  amount of the  indebtedness of the Borrower
hereunder  shall be accelerated  for any reason,  then such principal  amount so
accelerated  shall be credited  with any  interest  theretofore  paid thereon in
advance and remaining unearned at the time of such acceleration. If, pursuant to
the terms of this  Agreement or the Notes,  any funds are applied to the payment
of any  part  of  the  principal  amount  of the  indebtedness  of the  Borrower
hereunder  prior to the  maturity  thereof,  then (a) any  interest  which would
otherwise  thereafter accrue on the principal amount so paid by such application
shall be canceled,  and (b) the indebtedness of the Borrower hereunder remaining
unpaid after such application shall be credited with the amount of all interest,
if  any,  theretofore  collected  on  the  principal  amount  so  paid  by  such
application and remaining  unearned at the date of said application;  and if the
funds so applied shall be sufficient to pay in full all the  indebtedness of the
Borrower  hereunder,  then the Lenders shall refund to the Borrower all interest
theretofore  paid thereon in advance and remaining  unearned at the time of such
acceleration.  Regardless of any other provision in this Agreement, or in any of
the  written  evidences  of the  indebtedness  of the  Borrower  hereunder,  the
Borrower  shall  never  be  required  to  pay  any  unearned  interest  on  such
indebtedness or any portion thereof, and shall never be required to pay interest
thereon  at a rate in excess of the  Highest  Lawful  Rate  construed  by courts
having competent jurisdiction thereof. 13

     assigns,  the prompt and complete  payment and  performance by the Borrower
when due (whether at the stated  maturity,  by acceleration or otherwise) of the
Borrower Obligations.

     (b)  Anything  herein  or in  any  other  Loan  Document  to  the  contrary
notwithstanding, the maximum liability of each Guarantor hereunder and under the
other Loan Documents shall in no event exceed the amount which can be guaranteed
by such  Guarantor  under  applicable  federal  and state laws  relating  to the
insolvency  of  debtors  (after  giving  effect  to the  right  of  contribution
established in Section 2.2).

     (c) Each Guarantor agrees that the Borrower Obligations may at any time and
from time to time exceed the amount of the liability of such Guarantor hereunder
without  impairing  the  guarantee  contained in this Section 2 or affecting the
rights and remedies of the Collateral Agent or any Lender hereunder.

     (d) Subject to the limitations in Section 2.1(b),  the guarantee  contained
in this  Section 2 shall  remain in full force and effect until all the Borrower
Obligations and the obligations of each Guarantor under the guarantee  contained
in this  Section 2 shall have been  satisfied  by payment in full,  no Letter of
Credit  shall  be  outstanding   and  the   Commitments   shall  be  terminated,
notwithstanding  that from time to time during the term of the Credit  Agreement
the Borrower may be free from any Borrower Obligations.

     (e) No  payment  made by the  Borrower,  any of the  Guarantors,  any other
guarantor or any other  Person or received or  collected  by the  Administrative
Agent,  the  Collateral  Agent  or any  Lender  from  the  Borrower,  any of the
Guarantors,  any other  guarantor or any other Person by virtue of any action or
proceeding or any set-off or  appropriation  or  application at any time or from
time to time in reduction of or in payment of the Borrower  Obligations shall be
deemed to modify,  reduce,  release or  otherwise  affect the  liability  of any
Guarantor  hereunder which shall,  notwithstanding  any such payment (other than
any payment made by such Guarantor in respect of the Borrower Obligations or any
payment  received or  collected  from such  Guarantor in respect of the Borrower
Obligations),  remain  liable for the  Borrower  Obligations  up to the  maximum

     2.2 Right of Contribution.  Each Guarantor hereby agrees that to the extent
that a  Guarantor  shall  have  paid more  than its  proportionate  share of any
payment made  hereunder,  such  Guarantor  shall be entitled to seek and receive

Lender against the Borrower or any other Guarantor or any collateral security or
guarantee or right of offset held by the Collateral  Agent or any Lender for the
payment of the Borrower Obligations, nor shall any Guarantor seek or be entitled
to seek any  contribution  or  reimbursement  from  the  Borrower  or any  other

amounts owing to the Administrative  Agent, the Collateral Agent and the Lenders
by the  Borrower on account of the  Borrower  Obligations  are paid in full,  no
Letter of Credit shall be outstanding and the Commitments are terminated. If any
amount shall be paid to any Guarantor on account of such  subrogation  rights at
any time when all of the Borrower  Obligations shall not have been paid in full,
such amount shall be held by such Guarantor in trust for  Administrative  Agent,
the  Collateral  Agent and the  Lenders,  segregated  from  other  funds of such
Guarantor,  and shall, forthwith upon receipt by such Guarantor,  be turned over

Obligations made by the Administrative Agent, the Collateral Agent or any Lender
may be rescinded  by the  Administrative  Agent,  the  Collateral  Agent or such
Lender  and  any  of  the  Borrower  Obligations  continued,  and  the  Borrower
Obligations,  or the liability of any other Person upon or for any part thereof,
or any collateral security or guarantee therefor or right of offset with respect
thereto,  may,  from time to time,  in whole or in part,  be renewed,  extended,
amended, modified, accelerated,  compromised, waived, surrendered or released by
the  Administrative  Agent, the Collateral  Agent or any Lender,  and the Credit
Agreement  and the other Loan  Documents  and any other  documents  executed and
delivered in connection  therewith  may be amended,  modified,  supplemented  or
terminated,  in whole or in part, as Administrative  Agent, the Collateral Agent
(or the Required Lenders or all Lenders,  as the case may be) may deem advisable
from time to time, and any collateral security,  guarantee or right of offset at
any time held by the  Collateral  Agent or any  Lender  for the  payment  of the
Borrower Obligations may be sold,  exchanged,  waived,  surrendered or released.
Neither  the  Collateral  Agent nor any  Lender  shall  have any  obligation  to

notice of the  creation,  renewal,  extension  or accrual of any of the Borrower
Obligations and notice of or proof of reliance by the Administrative  Agent, the
Collateral Agent or any Lender upon the guarantee contained in this Section 2 or
acceptance  of  the  guarantee   contained  in  this  Section  2;  the  Borrower
Obligations, and any of them, shall conclusively be deemed to have been created,
contracted or incurred,  or renewed,  extended,  amended or waived,  in reliance
upon the  guarantee  contained in this  Section 2; and all dealings  between the
Borrower  and any of the  Guarantors,  on the one hand,  and the  Administrative
Agent, the Collateral Agent and the Lenders,  on the other hand,  likewise shall
be  conclusively  presumed to have been had or  consummated in reliance upon the
guarantee contained in this Section 2.

053113\0942\02497\9764JKRJ.GUA

     Each Guarantor waives diligence,  presentment,  protest, demand for payment
and  notice of  default  or  nonpayment  to or upon the  Borrower  or any of the
Guarantors with respect to the Borrower Obligations.  Each Guarantor understands
and agrees  that  subject to the  limitations  in Section  2.1(b) the  guarantee
contained in this Section 2 shall be  construed  as a  continuing,  absolute and
unconditional  guarantee  of  payment  without  regard  to (a) the  validity  or
enforceability  of the Credit  Agreement or any other Loan Document,  any of the
Borrower  Obligations or any other collateral  security therefor or guarantee or
right of offset  with  respect  thereto at any time or from time to time held by
the  Administrative  Agent, the Collateral Agent or any Lender, (b) any defense,
set-off or counterclaim  (other than a defense of payment or performance)  which
may at any time be  available  to or be  asserted  by the  Borrower or any other
Person against the Administrative  Agent, the Collateral Agent or any Lender, or
(c) any other circumstance whatsoever (with or without notice to or knowledge of
the  Borrower or such  Guarantor)  which  constitutes,  or might be construed to
constitute,  an  equitable  or legal  discharge of the Borrower for the Borrower
Obligations,  or of such Guarantor under the guarantee contained in this Section
2, in bankruptcy or in any other instance.  When making any demand  hereunder or
otherwise  pursuing its rights and  remedies  hereunder  against any  Guarantor,
Administrative Agent, the Collateral Agent or any Lender may, but shall be under
no obligation to, make a similar  demand on or otherwise  pursue such rights and
remedies as it may have against the Borrower,  any other  Guarantor or any other
Person  or  against  any  collateral  security  or  guarantee  for the  Borrower
Obligations or any right of offset with respect thereto,  and any failure by the
Administrative  Agent,  the  Collateral  Agent  or any  Lender  to make any such
demand,  to pursue such other rights or remedies or to collect any payments from
the  Borrower,  any other  Guarantor  or any other Person or to realize upon any
such  collateral  security or guarantee or to exercise any such right of offset,
or any release of the Borrower,  any other  Guarantor or any other Person or any
such collateral  security,  guarantee or right of offset,  shall not relieve any
Guarantor  of any  obligation  or liability  hereunder,  and shall not impair or
affect the rights and  remedies,  whether  express,  implied or  available  as a
matter of law, of the  Administrative  Agent, the Collateral Agent or any Lender
against any  Guarantor.  For the  purposes  hereof  "demand"  shall  include the
commencement and continuance of any legal proceedings.

     2.6 Reinstatement. The guarantee contained in this Section 2 shall continue
to be effective,  or be reinstated,  as the case may be, if at any time payment,
or any part  thereof,  of any of the Borrower  Obligations  is rescinded or must
otherwise be restored or returned by the  Administrative  Agent,  the Collateral
Agent or any Lender upon the insolvency, bankruptcy, dissolution, liquidation or
reorganization  of the Borrower or any Guarantor,  or upon or as a result of the
appointment of a receiver,  intervenor or conservator  of, or trustee or similar
officer  for,  the  Borrower or any  Guarantor  or any  substantial  part of its
property, or otherwise, all as though such payments had not been made.

     2.7 Payments. Each Guarantor hereby guarantees that payments hereunder will
be paid to the Collateral  Agent without set-off or  counterclaim  (other than a
defense of payment  and  performance  in full of the  Borrower  Obligations)  in
Dollars at the office of the Collateral  Agent located at 500 West Texas Avenue,

from taking such action by such Guarantor or any of its Subsidiaries.

     5.2 Delivery of Instruments  and Chattel Paper. If any amount payable under
or in connection with any of the Collateral  shall be or become evidenced by any
Instrument  or Chattel Paper in an amount in excess of $500,000 (or in excess of

otherwise satisfy at or before maturity or before they become delinquent, as the
case may be, all taxes,  assessments and governmental  charges or levies imposed

     (b) Such Grantor will furnish to the Collateral  Agent and the Lenders from
time to time  statements and schedules  further  identifying  and describing the
Collateral  and such other  reports in  connection  with the  Collateral  as the

including,  without  limitation,  the filing of any  financing  or  continuation
statements  under the Uniform  Commercial Code (or other similar laws) in effect
in any jurisdiction with respect to the security interests created hereby.

     5.6 Changes in Locations,  Name,  etc.  Such Grantor will not,  except upon
written notice to the Collateral  Agent and delivery (within 30 days thereafter)
to the Collateral Agent of (a) all additional executed financing  statements and
other  documents  reasonably  requested by the Collateral  Agent to maintain the
validity,  perfection and priority of the security interests provided for herein
and (b) if applicable, a written supplement to Schedule 5 showing any additional

goods) to be kept at a location other than those listed on Schedule 5;

     (ii) change the location of its chief executive office,  principal place of
business or office where records concerning the Accounts are kept, or sole place
of business from that referred to in Section 4.4; or

     (iii) change its name,  identity or  corporate  structure to such an extent

promptly, in reasonable detail, of:

     (a) any  Lien  (other  than  security  interests  created  hereby  or Liens
permitted  under the Credit  Agreement)  on any of the  Collateral  which  would
materially and adversely  affect the ability of the Collateral Agent to exercise
any of its remedies hereunder; and

     (b) of the occurrence of any other event which could reasonably be expected

Grantor  shall  accept the same as the agent of the  Administrative  Agent,  the
Collateral Agent and the Lenders,  hold the same in trust for the Administrative
Agent,  the  Collateral  Agent and the Lenders and deliver the same forthwith to

the  Collateral  Agent  so  requests,  signature  guaranteed,  to be held by the
Collateral Agent, subject to the terms hereof, as additional collateral security
for the Obligations.  Any sums paid upon or in respect of the Pledged Securities
upon the  liquidation  or dissolution of any Issuer (other than any amount which

distributed shall,  unless otherwise subject to a perfected security interest in
favor of the Collateral  Agent, be delivered to the Collateral  Agent to be held
by it hereunder as additional  collateral  security for the Obligations.  If any
such sums of money or property so paid or  distributed in respect of the Pledged
Securities  shall be received by such Grantor,  such Grantor  shall,  until such
money or property is paid or delivered to the Collateral  Agent, hold such money
or  property  in trust for the  Lenders,  segregated  from  other  funds of such
Grantor, as additional collateral security for the Obligations.

     (b) Without the prior written consent of the Collateral Agent, such Grantor
will not (i) sell, assign, transfer, exchange, or otherwise dispose of, or grant
any option with respect to, the Pledged  Securities or Proceeds  thereof (except
pursuant to a transaction permitted by the Credit Agreement), (ii) create, incur
or permit  to exist  any Lien or option in favor of, or any claim of any  Person
with  respect to, any of the Pledged  Securities  or  Proceeds  thereof,  or any

permitted  by the  Credit  Agreement  or  (iii)  enter  into  any  agreement  or
undertaking  restricting  the right or ability of such Grantor or the Collateral
Agent to sell,  assign or  transfer  any of the Pledged  Securities  or Proceeds
thereof.

     (c) In the case of each Grantor which is an Issuer, such Issuer agrees that
(i) it will be bound by the  terms of this  Agreement  relating  to the  Pledged
Securities  issued by it and will comply  with such terms  insofar as such terms
are  applicable  to it, (ii) it will  notify the  Collateral  Agent  promptly in
writing of the occurrence of any of the events  described in Section 5.8(a) with
respect to the Pledged  Securities  issued by it and (iii) the terms of Sections
6.3(c) and 6.7 shall apply to it, mutatis mutandis,  with respect to all actions
that may be required of it pursuant to Section 6.3(c) or 6.7 with respect to the
Pledged Securities issued by it.

     5.9  Receivables.  (a)  Other  than  in the  ordinary  course  of  business
consistent  with its reasonable  business  practices,  such Grantor will not (i)
grant any extension of the

053113\0942\02497\9764JKRJ.GUA

each and  every  trademark  class of goods  applicable  to its  current  line as

abandonment  for non-use,  (ii)  maintain as in the past the quality of products
and services  offered  under such  material  Trademark,  (iii) use such material
Trademark with the appropriate  notice of registration and all other notices and
legends  required by applicable  Requirements  of Law, (iv) not adopt or use any
mark which is  confusingly  similar or a colorable  imitation  of such  material
Trademark  unless the Collateral  Agent, for the ratable benefit of the Lenders,
shall  obtain a  perfected  security  interest  in such  mark  pursuant  to this
Agreement,  and (v) not (and not permit any licensee or sublicensee  thereof to)
do any act or knowingly  omit to do any act whereby such material  Trademark may
become invalidated or impaired in any way.

     (b) Except to the extent such  Grantor,  in the exercise of its  reasonable
business  judgment,  may elect not to do so and where its  failure to do so will
not have a Material  Adverse  Effect,  such  Grantor  (either  itself or through
licensees)  will not do any act,  or omit to do any act,  whereby  any  material
Patent may become forfeited, abandoned or dedicated to the public.

     (c) Except to the extent such  Grantor,  in the exercise of its  reasonable
business  judgment,  may elect not to do so and where its  failure to do so will

fall into the public domain.

     (d) Except to the extent such  Grantor,  in the exercise of its  reasonable
business  judgment,  may elect not to do so and where its  failure to do so will

business  judgment,  may elect not to do so and where its  failure to do so will
not have a Material  Adverse  Effect,  such Grantor  will notify the  Collateral
Agent and the Lenders  immediately if it knows,  or has reason to know, that any
application or registration  relating to any material  Intellectual Property may
become  forfeited,  abandoned  or  dedicated  to the  public,  or of any adverse
determination or development (including, without limitation, the institution of,
or any such determination or development in, any proceeding in the United States
Patent and Trademark Office,  the United States Copyright Office or any court or
tribunal in any country) regarding such Grantor's  ownership of, or the validity
of, any material  Intellectual  Property or such Grantor's right to register the

Adverse  Effect,  (i) take such actions as such Grantor  shall  reasonably  deem
appropriate under the  circumstances to protect such  Intellectual  Property and
(ii) if such  Intellectual  Property is of  material  economic  value,  promptly
notify the Collateral  Agent after it learns  thereof and sue for  infringement,
misappropriation or dilution, to seek injunctive relief where appropriate and to

                         SECTION 6. REMEDIAL PROVISIONS

     6.1 Certain Matters Relating to Receivables. (a) The Collateral Agent shall
have the right to make test  verifications  of the Receivables in any manner and
through any medium that it  reasonably  considers  advisable,  and each  Grantor
shall furnish all such  assistance and  information as the Collateral  Agent may
require in connection with such test verifications. At any time and from time to
time,  upon the Collateral  Agent's request and at the expense of the applicable
Grantor,  such Grantor  shall cause  independent  public  accountants  or others
satisfactory to the Collateral  Agent to furnish to the Collateral Agent reports
showing  reconciliations,  aging and test  verifications  of, and trial balances
for, the Receivables.

     (b) The  Collateral  Agent hereby  authorizes  each Grantor to collect such
Grantor's  Receivables;  provided,  however, the Collateral Agent may curtail or
terminate  said  authority  at any time  after the  occurrence  and  during  the
continuance of an Event of Default.  If required by the Collateral  Agent at any
time after the occurrence and during the continuance of an Event of Default, any
payments of Receivables,  when collected by any Grantor,  (i) shall be forthwith
(and, in any event,  within two Business Days)  deposited by such Grantor in the
exact form received,  duly indorsed by such Grantor to the  Collateral  Agent if
required, in a Collateral Account maintained under the sole dominion and control
of the Collateral  Agent,  subject to withdrawal by the Collateral Agent for the
account of the Lenders only as provided in Section 6.5, and (ii) until so turned
over,  shall be held by such Grantor in trust for the  Collateral  Agent and the
Lenders,  segregated  from other  funds of such  Grantor.  Each such  deposit of
Proceeds  of  Receivables  shall  be  accompanied  by a  report  identifying  in
reasonable detail the nature and source of the payments included in the deposit.

     (c) At the Collateral  Agent's request,  at any time during the continuance
of an Event of Default,  each Grantor shall deliver to the Collateral  Agent all
original and other  documents  evidencing,  and relating to, the  agreements and
transactions which gave rise to the Receivables,  including, without limitation,
all original orders, invoices and shipping receipts.

     6.2  Communications   with  Obligors;   Grantors  Remain  Liable.  (a)  The
Collateral  Agent in its own name or in the name of others may at any time after
the

053113\0942\02497\9764JKRJ.GUA

                                       18


     occurrence and during the  continuance  of an Event of Default  communicate
with  obligors  under  the  Receivables  to verify  with them to the  Collateral
Agent's satisfaction the existence, amount and terms of any Receivables.

     (b)  Upon the  request  of the  Collateral  Agent  at any  time  after  the
occurrence and during the continuance of an Event of Default, each Grantor shall
notify  obligors on the Receivables  that the Receivables  have been assigned to
the Collateral Agent for the ratable benefit of the Lenders and that payments in
respect thereof shall be made directly to the Collateral Agent.

     (c) Anything  herein to the contrary  notwithstanding,  each Grantor  shall
remain  liable  under each of the  Receivables  to observe  and  perform all the
conditions and obligations to be observed and performed by it thereunder, all in
accordance  with the terms of any  agreement  giving rise  thereto.  Neither the
Collateral Agent nor any Lender shall have any obligation or liability under any
Receivable (or any agreement giving rise thereto) by reason of or arising out of
this  Agreement  or the  receipt  by the  Collateral  Agent or any Lender of any
payment  relating  thereto,  nor shall  the  Collateral  Agent or any  Lender be
obligated in any manner to perform any of the  obligations  of any Grantor under
or pursuant to any  Receivable (or any agreement  giving rise thereto),  to make
any  payment,  to make any  inquiry as to the nature or the  sufficiency  of any
payment  received by it or as to the sufficiency of any performance by any party
thereunder,  to  present or file any  claim,  to take any action to enforce  any
performance  or to  collect  the  payment  of any  amounts  which  may have been
assigned to it or to which it may be entitled at any time or times.

     6.3 Pledged  Stock.  (a) Unless an Event of Default shall have occurred and
be continuing and the Collateral Agent shall have given notice to the applicable
Grantor of the Collateral  Agent's intent to exercise its  corresponding  rights
pursuant to Section 6.3(b),  each Grantor shall be permitted to receive all cash
dividends  paid in respect of the Pledged Stock and all payments made in respect
of the Pledged Notes,  in each case paid in the normal course of business of the
relevant Issuer and consistent with past practice and to exercise all voting and
corporate rights with respect to the Pledged Securities; provided, however, that
no vote shall be cast or corporate  right  exercised or other action taken which
would  materially  impair the Collateral or which would be inconsistent  with or
result in any violation of any provision of the Credit Agreement, this Agreement
or any other Loan Document.

     (b) If an Event of Default shall occur and be continuing and the Collateral
Agent shall give notice of its intent to exercise such rights to the  applicable
Grantor or Grantors,  (i) the  Collateral  Agent shall have the right to receive
any and all cash  dividends,  payments or other  Proceeds paid in respect of the
Pledged Securities and make application thereof to the Obligations, and (ii) any
or all of  the  Pledged  Securities  shall  be  registered  in the  name  of the
Collateral  Agent or its nominee,  and the  Collateral  Agent or its nominee may
thereafter  exercise (x) all voting,  corporate  and other rights  pertaining to
such Pledged Securities at any meeting of shareholders of the relevant Issuer or
Issuers or  otherwise  and (y) any and all rights of  conversion,  exchange  and
subscription  and any other  rights,  privileges  or options  pertaining to such
Pledged Securities as if it were the absolute owner thereof (including,  without
limitation,  the right to exchange at its  discretion any and all of the Pledged
Securities upon the merger, consolidation,  reorganization,  recapitalization or
other

053113\0942\02497\9764JKRJ.GUA

     fundamental  change in the corporate  structure of any Issuer,  or upon the
exercise  by any  Grantor or the  Collateral  Agent of any right,  privilege  or
option pertaining to such Pledged Securities,  and in connection therewith,  the
right to deposit  and deliver  any and all of the  Pledged  Securities  with any
committee, depositary, transfer agent, registrar or other designated agency upon
such terms and conditions as the Collateral  Agent may  determine),  all without
liability  except to  account  for  property  actually  received  by it, but the
Collateral  Agent shall have no duty to any Grantor to exercise  any such right,
privilege  or option and shall not be  responsible  for any  failure to do so or
delay in so doing.

     (c) Each Grantor hereby authorizes and instructs each Issuer of any Pledged
Securities  pledged by such  Grantor  hereunder  to comply with any  instruction
received  by it from the  Collateral  Agent in writing  that (x) states  that an
Event  of  Default  has  occurred  and is  continuing  and (y) is  otherwise  in
accordance  with the  terms of this  Agreement,  without  any  other or  further
instructions  from such Grantor,  and each Grantor agrees that each Issuer shall
be fully protected in so complying.

     6.4  Proceeds to be Turned  Over To  Collateral  Agent.  In addition to the
rights of the  Collateral  Agent and the Lenders  specified  in Section 6.1 with
respect to payments of  Receivables,  if an Event of Default  shall occur and be
continuing  and the  Collateral  Agent shall have given notice to the applicable
Grantor,  all Proceeds  received by any Grantor  consisting of cash,  checks and
other  near-cash items shall be held by such Grantor in trust for the Collateral
Agent and the Lenders,  segregated from other funds of such Grantor,  and shall,
forthwith upon receipt by such Grantor,  be turned over to the Collateral  Agent
in the exact form received by such Grantor (duly indorsed by such Grantor to the
Collateral  Agent, if required).  All Proceeds  received by the Collateral Agent
hereunder  shall  be  held  by the  Collateral  Agent  in a  Collateral  Account
maintained  under its sole dominion and control.  All Proceeds while held by the
Collateral  Agent in a  Collateral  Account (or by such Grantor in trust for the
Collateral  Agent  and the  Lenders)  shall  continue  to be held as  collateral
security for all the Obligations and shall not constitute  payment thereof until
applied as provided in Section 6.5.

     6.5 Application of Proceeds. At such intervals as may be agreed upon by the
Borrower  and the  Collateral  Agent,  or,  if an Event of  Default  shall  have
occurred and be continuing,  at any time at the Collateral Agent's election, the
Collateral Agent may apply all or any part of Proceeds constituting  Collateral,
whether or not held in any Collateral Account, and any proceeds of the guarantee
set forth in Section 2, in payment of the Obligations in the following order:

     First, to pay incurred and unpaid fees and expenses of the Collateral Agent
and the Administrative Agent under the Loan Documents;

     Second, to the Administrative  Agent, for application by it towards payment
of  amounts  then  due  and  owing  and  remaining  unpaid  in  respect  of  the
Obligations,  pro  rata  among  the  Lenders  according  to the  amounts  of the
Obligations then due and owing and remaining unpaid to the Lenders;


053113\0942\02497\9764JKRJ.GUA

<PAGE>

                                       20


     Third,  to  the  Administrative   Agent,  for  application  by  it  towards
prepayment  of the  Obligations,  pro rata among the  Lenders  according  to the
amounts of the Obligations then held by the Lenders; and

     Fourth,  any balance of such Proceeds remaining after the Obligations shall
have been  paid in full,  no  Letters  of Credit  shall be  outstanding  and the
Commitments  shall  have  terminated  shall be paid over to the  Borrower  or to
whomsoever may be lawfully entitled to receive the same.

     6.6 Code and Other  Remedies.  If an Event of  Default  shall  occur and be
continuing,  the Collateral  Agent, on behalf of the Lenders,  may exercise,  in
addition to all other rights and remedies  granted to them in this Agreement and
in any other  instrument  or agreement  securing,  evidencing or relating to the
Obligations,  all rights and remedies of a secured  party under the New York UCC
or any other  applicable law.  Without limiting the generality of the foregoing,
the   Collateral   Agent,   without  demand  of  performance  or  other  demand,
presentment,  protest,  advertisement  or notice of any kind  (except any notice
required by law  referred  to below) to or upon any Grantor or any other  Person
(all and each of which demands, defenses,  advertisements and notices are hereby
waived), may in such circumstances forthwith collect,  receive,  appropriate and
realize upon the  Collateral,  or any part thereof,  and/or may forthwith  sell,
lease,  assign, give option or options to purchase,  or otherwise dispose of and
deliver  the  Collateral  or any  part  thereof  (or  contract  to do any of the
foregoing),  in one or more parcels at public or private  sale or sales,  at any
exchange,  broker's  board or office of the  Collateral  Agent or any  Lender or
elsewhere  upon such terms and  conditions as it may deem  advisable and at such
prices as it may deem best, for cash or on credit or for future delivery without
assumption of any credit risk. The Administrative Agent, the Collateral Agent or
any Lender shall have the right upon any such public sale or sales,  and, to the
extent  permitted by law,  upon any such private sale or sales,  to purchase the
whole or any part of the  Collateral  so sold,  free of any  right or  equity of
redemption in any Grantor,  which right or equity is hereby waived and released.
Each Grantor further agrees, at the Collateral Agent's request,  to assemble the
Collateral  and make it  available to the  Collateral  Agent at places which the
Collateral Agent shall reasonably select,  whether at such Grantor's premises or
elsewhere. The Collateral Agent shall apply the net proceeds of any action taken
by it pursuant to this Section 6.6,  after  deducting all  reasonable  costs and
expenses of every kind  incurred in  connection  therewith or  incidental to the
care or  safekeeping  of any of the  Collateral  or in any way  relating  to the
Collateral  or the rights of the  Collateral  Agent and the  Lenders  hereunder,
including, without limitation,  reasonable attorneys' fees and disbursements, to
the  payment in whole or in part of the  Obligations,  in the order set forth in
Section  6.5,  and only  after  such  application  and after the  payment by the
Collateral  Agent  of any  other  amount  required  by  any  provision  of  law,
including, without limitation, Section 9-504(1)(c) of the New York UCC, need the
Collateral Agent account for the surplus,  if any, to any Grantor. To the extent
permitted by applicable law, each Grantor waives all claims, damages and demands
it may acquire  against the  Collateral  Agent or any Lender  arising out of the
exercise by them of any rights  hereunder.  If any notice of a proposed  sale or
other  disposition of Collateral  shall be required by law, such notice shall be
deemed reasonable and proper if given at least 10 days before such sale or other
disposition.

     6.7 Private Sales.  (a) Each Grantor  recognizes that the Collateral  Agent
may be unable to effect a public sale of any or all the Pledged Stock, by reason
of certain  prohibitions  contained in the Securities  Act and applicable  state
securities  laws or  otherwise,  and may be  compelled  to resort to one or more
private sales thereof to a restricted  group of purchasers which will be obliged
to agree,  among other things,  to acquire such securities for their own account
for investment and not with a view to the  distribution or resale thereof.  Each
Grantor  acknowledges and agrees that any such private sale may result in prices
and  other  terms  less  favorable  than if such  sale  were a public  sale and,
notwithstanding  such circumstances,  agrees that any such private sale shall be
deemed to have been made in a  commercially  reasonable  manner.  The Collateral
Agent shall be under no  obligation  to delay a sale of any of the Pledged Stock
for the period of time  necessary to permit the Issuer  thereof to register such
securities for public sale under the Securities Act, or under  applicable  state
securities laws, even if such Issuer would agree to do so.

     (b) Each  Grantor  agrees to use its best efforts to do or cause to be done
all such other acts as may be necessary to make such sale or sales of all or any
portion of the Pledged Stock  pursuant to this Section 6.7 valid and binding and
in  compliance  with any and all  other  applicable  Requirements  of Law.  Each
Grantor  further agrees that a breach of any of the covenants  contained in this
Section  6.7 will  cause  irreparable  injury  to the  Collateral  Agent and the
Lenders,  that the Collateral  Agent and the Lenders have no adequate  remedy at
law in  respect  of such  breach  and,  as a  consequence,  that  each and every
covenant contained in this Section 6.7 shall be specifically enforceable against
such  Grantor,  and such  Grantor  hereby  waives  and  agrees not to assert any
defenses against an action for specific performance of such covenants except for
a defense  that no Event of Default has  occurred  and is  continuing  under the
Credit Agreement.

     6.8 Waiver;  Deficiency.  Each Grantor  waives and agrees not to assert any
rights or  privileges  which it may acquire  under Section 9-112 of the New York
UCC. Each Grantor shall remain liable for any  deficiency if the proceeds of any
sale  or  other  disposition  of the  Collateral  are  insufficient  to pay  its
Obligations  and the fees and  disbursements  of any  attorneys  employed by the
Collateral Agent or any Lender to collect such deficiency.


                         SECTION 7. THE COLLATERAL AGENT

     7.1  Collateral  Agent's  Appointment  as  Attorney-in-Fact,  etc. (a) Each
Grantor hereby irrevocably constitutes and appoints the Collateral Agent and any
officer  or agent  thereof,  with full  power of  substitution,  as its true and
lawful  attorney-in-fact  with full irrevocable power and authority in the place
and stead of such  Grantor  and in the name of such  Grantor or in its own name,
for the purpose of carrying out the terms of this Agreement, to take any and all
appropriate  action and to execute any and all documents and  instruments  which
may be necessary or desirable to accomplish the purposes of this Agreement, and,
without limiting the generality of the foregoing,  each Grantor hereby gives the
Collateral Agent the power and right, on behalf of such Grantor,  without notice
to or assent by such Grantor, to do any or all of the following:


053113\0942\02497\9764JKRJ.GUA

                                       22


     (i) in the  name of  such  Grantor  or its own  name,  or  otherwise,  take
possession of and indorse and collect any checks, drafts, notes,  acceptances or
other instruments for the payment of moneys due under any Receivable or Contract
or with  respect  to any other  Collateral  and file any claim or take any other
action  or  proceeding  in any  court  of  law or  equity  or  otherwise  deemed
appropriate  by the  Collateral  Agent for the purpose of collecting any and all
such moneys due under any  Receivable  or Contract or with  respect to any other
Collateral whenever payable;

     (ii) in the case of any  Intellectual  Property,  execute and deliver,  and
have recorded, any and all agreements,  instruments, documents and papers as the
Collateral Agent may request to evidence the Collateral Agent's and the Lenders'
security  interest in such  Intellectual  Property  and the goodwill and general
intangibles of such Grantor relating thereto or represented thereby;

     (iii) pay or discharge  taxes and Liens  levied or placed on or  threatened
against the  Collateral,  effect any repairs or any insurance  called for by the
terms of this Agreement and pay all or any part of the premiums therefor and the
costs thereof;

     (iv) execute,  in  connection  with any sale provided for in Section 6.6 or
6.7,  any  indorsements,  assignments  or other  instruments  of  conveyance  or
transfer with respect to the Collateral; and

     (v) (1) direct any party liable for any payment under any of the Collateral
to make payment of any and all moneys due or to become due  thereunder  directly
to the  Collateral  Agent or as the  Collateral  Agent shall direct;  (2) ask or
demand for, collect, and receive payment of and receipt for, any and all moneys,
claims  and other  amounts  due or to become  due at any time in  respect  of or
arising out of any  Collateral;  (3) sign and indorse any  invoices,  freight or
express bills, bills of lading,  storage or warehouse  receipts,  drafts against
debtors, assignments,  verifications,  notices and other documents in connection
with any of the  Collateral;  (4) commence and prosecute  any suits,  actions or
proceedings  at law or in  equity  in any  court of  competent  jurisdiction  to
collect the Collateral or any portion  thereof and to enforce any other right in
respect of any  Collateral;  (5) defend any suit,  action or proceeding  brought
against such Grantor with respect to any Collateral;  (6) settle,  compromise or
adjust any such suit,  action or proceeding and, in connection  therewith,  give
such discharges or releases as the Collateral  Agent may deem  appropriate;  (7)
assign any  Copyright,  Patent or  Trademark  (along  with the  goodwill  of the
business to which any such Copyright, Patent or Trademark pertains),  throughout
the world for such term or terms, on such conditions, and in such manner, as the
Collateral  Agent shall in its sole  discretion  determine;  and (8)  generally,
sell, transfer,  pledge and make any agreement with respect to or otherwise deal
with any of the  Collateral  as fully and  completely  as though the  Collateral
Agent  were  the  absolute  owner  thereof  for all  purposes,  and  do,  at the
Collateral Agent's option and such Grantor's expense,  at any time, or from time
to time,  all acts and things  which the  Collateral  Agent deems  necessary  to
protect,  preserve or realize upon the Collateral and the Collateral Agent's and
the  Lenders'  security  interests  therein  and to  effect  the  intent of this
Agreement, all as fully and effectively as such Grantor might do.

053113\0942\02497\9764JKRJ.GUA

                                       23



     Anything  in this  Section  7.1(a)  to the  contrary  notwithstanding,  the
Collateral  Agent agrees that it will not exercise any rights under the power of
attorney  provided for in this Section  7.1(a)  unless an Event of Default shall
have occurred and be continuing.

     (b) If any Grantor  fails to perform or comply  with any of its  agreements
contained  herein,  the  Collateral  Agent,  at  its  option,  but  without  any
obligation so to do, may perform or comply,  or otherwise  cause  performance or
compliance, with such agreement.

     (c) The  expenses  of the  Collateral  Agent  incurred in  connection  with
actions  undertaken  as provided in this Section  7.1,  together  with  interest
thereon at a rate per annum equal to the rate per annum at which  interest would
then be  payable on past due Base Rate Loans  that are  Revolving  Credit  Loans
under the Credit Agreement,  from the date of payment by the Collateral Agent to
the date reimbursed by the relevant Grantor, shall be payable by such Grantor to
the Collateral Agent on demand.

     (d) Each Grantor hereby  ratifies all that said attorneys shall lawfully do
or cause to be done by virtue hereof.  All powers,  authorizations  and agencies
contained in this  Agreement  are coupled  with an interest and are  irrevocable
until this Agreement is terminated and the security interests created hereby are
released.

     7.2 Duty of Collateral Agent. The Collateral Agent's sole duty with respect
to the custody,  safekeeping and physical  preservation of the Collateral in its
possession,  under Section  9-207 of the New York UCC or otherwise,  shall be to
deal with it in the same  manner as the  Collateral  Agent  deals  with  similar
property for its own account.  Neither the Collateral  Agent, any Lender nor any
of their respective officers, directors, employees or agents shall be liable for
failure to demand,  collect or  realize  upon any of the  Collateral  or for any
delay in doing so or shall be under any obligation to sell or otherwise  dispose
of any Collateral upon the request of any Grantor or any other Person or to take
any other action  whatsoever  with regard to the Collateral or any part thereof.
The powers  conferred  on the  Collateral  Agent and the Lenders  hereunder  are
solely to protect the  Collateral  Agent's  and the  Lenders'  interests  in the
Collateral and shall not impose any duty upon the Collateral Agent or any Lender
to exercise  any such  powers.  The  Collateral  Agent and the Lenders  shall be
accountable  only for  amounts  that they  actually  receive  as a result of the
exercise of such powers, and neither they nor any of their officers,  directors,
employees or agents shall be  responsible  to any Grantor for any act or failure
to act hereunder, except for their own gross negligence or willful misconduct.

     7.3 Execution of Financing Statements. Pursuant to Section 9-402 of the New
York UCC and any other  applicable  law, each Grantor  authorizes the Collateral
Agent to file or  record  financing  statements  and other  filing or  recording
documents or instruments with respect to the Collateral without the signature of
such Grantor in such form and in such offices as the Collateral Agent reasonably
determines appropriate to perfect the security interests of the Collateral Agent
under this  Agreement.  A photographic  or other  reproduction of this Agreement
shall be  sufficient  as a  financing  statement  or other  filing or  recording
document or instrument for filing or recording in any jurisdiction.


053113\0942\02497\9764JKRJ.GUA

                                       24


     7.4  Authority of  Collateral  Agent.  Each Grantor  acknowledges  that the
rights and  responsibilities  of the Collateral  Agent under this Agreement with
respect  to any  action  taken  by the  Collateral  Agent  or  the  exercise  or
non-exercise  by the  Collateral  Agent of any option,  voting  right,  request,
judgment or other right or remedy  provided  for herein or  resulting or arising
out of this Agreement shall, as between the Collateral Agent and the Lenders, be
governed  by the Credit  Agreement  and by such other  agreements  with  respect
thereto  as may  exist  from  time to time  among  them,  but,  as  between  the
Collateral  Agent and the Grantors,  the Collateral  Agent shall be conclusively
presumed to be acting as agent for the Lenders with full and valid  authority so
to act or refrain from acting, and no Grantor shall be under any obligation,  or
entitlement, to make any inquiry respecting such authority.


                            SECTION 8. MISCELLANEOUS

     8.1  Amendments  in  Writing.  None  of the  terms  or  provisions  of this
Agreement may be waived,  amended,  supplemented or otherwise modified except in
accordance with Section 10.1 of the Credit Agreement.

     8.2 Notices.  All notices,  requests and demands to or upon the  Collateral
Agent or any Grantor  hereunder  shall be effected in the manner provided for in
Section 10.2 of the Credit Agreement;  provided that any such notice, request or
demand to or upon any  Guarantor  shall be  addressed  to such  Guarantor at its
notice address set forth on Schedule 1.

     8.3 No Waiver  by  Course of  Conduct;  Cumulative  Remedies.  Neither  the
Collateral Agent nor any Lender shall by any act (except by a written instrument
pursuant to Section 8.1), delay, indulgence,  omission or otherwise be deemed to
have waived any right or remedy  hereunder or to have  acquiesced in any Default
or Event of Default. No failure to exercise, nor any delay in exercising, on the
part of the  Collateral  Agent or any  Lender,  any  right,  power or  privilege
hereunder  shall operate as a waiver thereof.  No single or partial  exercise of
any right,  power or  privilege  hereunder  shall  preclude any other or further
exercise  thereof or the  exercise of any other  right,  power or  privilege.  A
waiver by the Collateral Agent or any Lender of any right or remedy hereunder on
any one  occasion  shall not be  construed as a bar to any right or remedy which
the Collateral Agent or such Lender would otherwise have on any future occasion.
The rights and remedies herein provided are cumulative,  may be exercised singly
or concurrently  and are not exclusive of any other rights or remedies  provided
by law.

     8.4 Enforcement Expenses; Indemnification. (a) Each Guarantor agrees to pay
or reimburse each Lender and the Collateral Agent for all its costs and expenses
incurred in collecting  against such Guarantor under the guarantee  contained in
Section 2 or otherwise  enforcing or preserving  any rights under this Agreement
and the other Loan  Documents  to which such  Guarantor  is a party,  including,
without limitation,  the fees and disbursements of counsel to each Lender and of
counsel to the Collateral Agent.

     (b) Each Guarantor  agrees to pay, and to save the Collateral Agent and the
Lenders  harmless  from, any and all  liabilities  with respect to, or resulting
from any delay in paying, any and all stamp,  excise, sales or other taxes which
may be payable or determined to

053113\0942\02497\9764JKRJ.GUA

     be payable with respect to any of the Collateral or in connection  with any
of the transactions contemplated by this Agreement.

     (c) Each Guarantor  agrees to pay, and to save the Collateral Agent and the
Lenders harmless from, any and all liabilities,  obligations,  losses,  damages,
penalties,  actions,  judgments,  suits, costs, expenses or disbursements of any
kind or nature whatsoever with respect to the execution, delivery,  enforcement,
performance  and  administration  of this  Agreement  to the extent the Borrower
would be required to do so pursuant to Section 10.5 of the Credit Agreement.

     (d) The  agreements  in this  Section 8.4 shall  survive  repayment  of the
Obligations  and all other amounts  payable  under the Credit  Agreement and the
other Loan Documents.

     8.5  Successors  and  Assigns.  This  Agreement  shall be binding  upon the
successors  and  assigns of each  Grantor  and shall inure to the benefit of the
Administrative  Agent, the Collateral Agent and the Lenders and their successors
and assigns;  provided  that no Grantor may assign,  transfer or delegate any of
its rights or obligations under this Agreement without the prior written consent
of the Collateral Agent.

     8.6 Set-Off. Each Grantor hereby irrevocably  authorizes the Administrative
Agent,  the  Collateral  Agent and each Lender at any time and from time to time
while an Event of Default pursuant to Section 8(a) of the Credit Agreement shall
have  occurred and be  continuing,  without  notice to such Grantor or any other
Grantor,  any such notice being expressly waived by each Grantor, to set-off and
appropriate and apply any and all deposits (general or special,  time or demand,
provisional or final), in any currency,  and any other credits,  indebtedness or
claims,  in any currency,  in each case whether direct or indirect,  absolute or
contingent,   matured  or   unmatured,   at  any  time  held  or  owing  by  the
Administrative  Agent,  the Collateral Agent or such Lender to or for the credit
or the  account of such  Grantor,  or any part  thereof  in such  amounts as the
Administrative Agent, the Collateral Agent or such Lender may elect, against and
on  account  of  the   obligations  and  liabilities  of  such  Grantor  to  the
Administrative  Agent,  the Collateral Agent or such Lender hereunder and claims
of every nature and  description  of the  Administrative  Agent,  the Collateral
Agent or such Lender  against such  Grantor,  in any currency,  whether  arising
hereunder,  under the Credit Agreement, any other Loan Document or otherwise, as
the Administrative Agent, the Collateral Agent or such Lender may elect, whether
or not the  Collateral  Agent or any Lender has made any demand for  payment and
although  such  obligations,   liabilities  and  claims  may  be  contingent  or
unmatured.  The  Collateral  Agent and each Lender  shall  notify  such  Grantor
promptly of any such  set-off  and the  application  made by the  Administrative
Agent,  the Collateral  Agent or such Lender of the proceeds  thereof,  provided
that the  failure to give such  notice  shall not affect  the  validity  of such
set-off and application.  The rights of the Administrative Agent, the Collateral
Agent and each Lender under this Section 8.6 are in addition to other rights and
remedies  (including,  without  limitation,  other rights of set-off)  which the
Administrative Agent, the Collateral Agent or such Lender may have.

     8.7  Counterparts.  This  Agreement  may be  executed by one or more of the
parties to this Agreement on any number of separate  counterparts  (including by
telecopy),  and all of said  counterparts  taken  together  shall be  deemed  to
constitute one and the same instrument.

     8.8  Severability.  Any provision of this Agreement  which is prohibited or
unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective
to the extent of such prohibition or unenforceability  without  invalidating the
remaining provisions hereof, and any such prohibition or unenforceability in any
jurisdiction shall not invalidate or render  unenforceable such provision in any
other jurisdiction.

     8.9 Section  Headings.  The Section headings used in this Agreement are for
convenience of reference only and are not to affect the  construction  hereof or
be taken into consideration in the interpretation hereof.

the Lenders with respect to the subject matter hereof and thereof, and there are
no promises,  undertakings,  representations or warranties by the Administrative
Agent,  the Collateral Agent or any Lender relative to subject matter hereof and
thereof  not  expressly  set forth or  referred  to herein or in the other  Loan
Documents.

and unconditionally:

     (a) submits for itself and its property in any legal  action or  proceeding
relating to this  Agreement and the other Loan Documents to which it is a party,
or for recognition and  enforcement of any judgment in respect  thereof,  to the
non-exclusive  general  jurisdiction of the Courts of the State of New York, the
courts of the  United States  of America for the Southern  District of New York,

     (b)  consents  that any such  action or  proceeding  may be brought in such

proceeding was brought in an inconvenient court and agrees not to plead or claim
the same;

     (c) agrees that service of process in any such action or proceeding  may be
effected  by mailing a copy  thereof by  registered  or  certified  mail (or any
substantially  similar form of mail),  postage  prepaid,  to such Grantor at its

have to claim or recover in any legal action or  proceeding  referred to in this
Section any special, exemplary, punitive or consequential damages.

     (b) neither the  Administrative  Agent, the Collateral Agent nor any Lender
has any fiduciary  relationship with or duty to any Grantor arising out of or in
connection  with this  Agreement  or any of the other  Loan  Documents,  and the
relationship  between  the  Grantors,  on the one hand,  and the  Administrative

Lenders or among the Grantors and the Lenders.

     8.14  WAIVER  OF  JURY  TRIAL.   EACH  GRANTOR   HEREBY   IRREVOCABLY   AND

Agreement  shall  become a  Grantor  for all  purposes  of this  Agreement  upon
execution and delivery by such Subsidiary of an Assumption Agreement in the form
of Annex 1 hereto.

     8.16 Releases. (a) At such time as the Loans, the Reimbursement Obligations
and the other  Obligations  shall have been paid in full, the  Commitments  have
been  terminated and no Letters of Credit shall be  outstanding,  the Collateral
shall be released  from the Liens  created  hereby,  and this  Agreement and all
obligations  (other than those expressly stated to survive such  termination) of
the Collateral  Agent and each Grantor  hereunder shall  terminate,  all without
delivery  of any  instrument  or  performance  of any act by any party,  and all
rights to the Collateral  shall revert to the Grantors.  At the request and sole
expense of any Grantor  following any such  termination,  the  Collateral  Agent
shall  deliver to such  Grantor  any  Collateral  held by the  Collateral  Agent
hereunder,  and execute  and  deliver to such  Grantor  such  documents  as such
Grantor shall reasonably request to evidence such termination.
