                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                 March 31, 1997

1.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

The Company

The consolidated  financial  information in this report includes the accounts of
Key Energy Group, Inc. (the "Company") and its wholly-owned subsidiaries and was
prepared in  conformity  with  accounting  policies used in the Annual Report on
Form 10-K furnished for the preceding fiscal year.

As of May 14, 1997,  the Company  operates 415 well service and workover rigs in
the United States, which is the third largest fleet of well service and workover
rigs in the United States. The Company operates in Texas,  Oklahoma, New Mexico,
Michigan  and the  Appalachian  Basin  and is a leader  in each of its  domestic
markets. The Company generally provides a full range of maintenance and workover
rig services to oil and gas  producers in each of its operating  regions.  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
hot oiling, oil field liquid  transportation,  storage and disposal, and fishing
tools and  services.  The Company also is engaged in the  production  of oil and
natural  gas and  contract  drilling  in the  Permian  Basin of West  Texas.  In
addition,  the Company  operates ten workover  rigs and three  drilling  rigs in
Argentina.

The  Company  conducts  its  operations   primarily  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  in 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.  Odessa
Exploration  is engaged in the production of oil and gas and Clint Hurt provides
contract oil and gas well drilling services.

In  July  1996,  the  Company  completed  the  offering  of  $52,000,000  of  7%
convertible subordinated debentures due 2003 (the "Offering").  The Offering was
a private  offering  pursuant to Rule 144A under the  Securities Act of 1933, as
amended  (the  "Securities  Act").  Proceeds  from  the  Offering  were  used to
substantially repay existing long-term debt (approximately  $35.4 million).  The
remaining proceeds, together with proceeds from borrowings under existing credit
arrangements,  were  used to fund  the  expansion  of the  Company's  operations
through  acquisitions  of  businesses  and assets and for  working  capital  and
general corporate  purposes.  See Note 3 for a more detailed  description of the
Offering.

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 based on proved reserves  expressed as net equivalent
barrels as reviewed by independent petroleum engineers.  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.

                                      - 6 -

Odessa Exploration's aggregate oil and gas properties are stated at cost, not in
excess of total estimated future net revenues net of related income tax effects.

financial  statements  contain all normal  recurring  adjustments  necessary  to
present  fairly the  financial  position as of March 31, 1997,  the statement of
cash flows for the three and nine months ended March 31, 1997 and 1996,  and the

In  July  1996,  the  Company  completed  the  offering  of  $52,000,000  of  7%

a private  offering  pursuant  to Rule  144A  under the  Securities  Act.  Gross
proceeds from the Offering were $52,000,000 and were used to substantially repay
existing long-term debt  (approximately  $35.4 million).  The remaining proceeds
were used to fund the expansion of the Company's operations through acquisitions
of businesses and assets, for working capital and general corporate purposes.

The long-term debt that was repaid with proceeds from the Offering  consisted of
(i)  indebtedness  under the term  notes  with CIT  Group/Credit  Finance,  Inc.
("CIT")  aggregating  approximately $21.2 million and (ii) all indebtedness owed
by  Odessa  Exploration  to  Norwest  Bank  Texas,  N.A.   ("Norwest")  totaling
approximately $14.2 million.

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.

The  Debentures  are not  redeemable  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 Debenture  prospectus,
together with accrued and unpaid  interest  thereon.  The Debentures also may be
redeemed at the option of the holder if there is a change in control (as defined
in the  original  Debenture  prospectus)  at 100%  of  their  principal  amount,
together with accrued and unpaid interest thereon.

Pursuant to the terms of the  Indenture  governing  the rights of the holders of
the  Offering,  the Company was required to obtain  Servicios'  guarantee of the
Company's  indebtedness  under the  offering and agreed to increase the interest
rate  payable on the  offering  to 7 1/2 % in the event such  guarantee  was not
obtained.  To date, such guarantee has not been obtained,  and,  therefore,  the
Offering is currently  accruing  interest at a rate of 7 1/2%.  The Company made
its first interest payment on December 31, 1996.

Other Long-term Debt

In March 1997, the Company  completed the renegotiation of its credit facilities
with CIT  consisting  of a line of  credit  and term  loan for each of  WellTech
Eastern, Yale E. Key and Clint Hurt. The renegotiated term and credit facilities
include a maximum credit  availability of the lesser of (i) $55 million, or (ii)
an amount  subject to certain  asset  valuations  determined by CIT.  Also,  the
re-negotiated term and credit facilities include an interest rate at one-quarter
percent above the stated prime rate, which was 8.25% at March 31, 1997.

The CIT line of credit, as amended,  ($14,787,000  approximate  balance at March
31, 1997) requires  monthly  payments of interest and is  collateralized  by the
accounts  receivable of Yale E. Key, Clint Hurt and WellTech  Eastern.  At March
31, 1997, there was no credit line availability.

The CIT note, as amended,  ($25,500,000  approximate  balance at March 31, 1997)
requires monthly payments of interest and is collateralized by all of the assets
of Yale E. Key, Clint Hurt and WellTech  Eastern.  At March 31, 1997,  there was
approximately $3.5 million in unused term loan facilities.

In  addition to the CIT credit  facilities,  Odessa  Exploration  has funded its
operations and acquisitions in part through a credit facility with Norwest.  All
amounts  previously owed by Odessa  Exploration  under the Norwest facility were
paid using a portion of the proceeds  from the Offering.  Effective  January 31,
1997,  Odessa  Exploration  completed the  renegotiation  of the Norwest  credit
facility,  which,  among  other  things,  increased  its  borrowing  base to $18
million, of which $1.2 million had been advanced as of March 31, 1997.

4.  IMPAIRMENT OF LONG-LIVED ASSETS

The Company  adopted FAS 121 effective as of July 1, 1996. FAS 121 requires that
long-lived  assets held and used by an entity,  including oil and gas properties
accounted for under the successful efforts method of accounting, be reviewed for
impairment  whenever  events  or  changes  in  circumstances  indicate  that the
carrying  amount of an asset  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 FAS 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 oil and gas  properties  and
compared  such  future  cash  flows to the  carrying  amount  of the oil and gas
properties to determine if the carrying  amount was  recoverable.  Based on this
process,  no writedown in the carrying amount of the Company's proved properties
was necessary at March 31, 1997.

5.  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.

RESULTS OF OPERATIONS
QUARTER ENDED MARCH  31, 1997 VERSUS QUARTER ENDED MARCH 31, 1996

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.

Operating  results for the quarter  ended March 31, 1997  include the  Company's
oilfield well service  operations  conducted by its  wholly-owned  subsidiaries,
Yale E.  Key,  Inc.  ("Yale E.  Key") and  WellTech  Eastern,  Inc.,  ("WellTech
Eastern"),  its  oil and  natural  gas  exploration  and  production  operations
conducted by its wholly-owned  subsidiary,  Odessa  Exploration,  Inc.  ("Odessa
Exploration")  and Key Energy  Drilling,  Inc. d/b/a Clint Hurt Drilling ("Clint
Hurt Drilling") which is engaged in oil and natural gas well contract  drilling.
In addition,  the Company  conducts  oilfield  service  operations  in Argentina
through  its  63%  ownership  in  Servicios  WellTech,  S.A.  ("Servicios"),  an
Argentinean corporation.

Historically,  fluctuations in oilfield well service  operations and oil and gas
well contract  drilling  activity have been closely  linked to  fluctuations  in
crude oil and natural gas prices.  However, the Company,  through  acquisitions,
customer alliances and agreements,  and  diversification  of services,  seeks to
minimize the effects of such fluctuations on the Company's results of operations
and financial condition.

The Company

Revenues  of the  Company  for  the  quarter  ended  March  31,  1997  increased
$28,748,000 or 201% to $43,050,000  from $14,302,000 for the quarter ended March
31, 1996, while net income of $2,365,000  represented an increase of $1,538,000,
or 186%,  from the 1996 quarter total of $827,000.  The increase in revenues was
primarily  due  to  increased   oilwell  service  equipment   utilization,   the
acquisition of the WellTech  Eastern  operations from the date of acquisition of
March 26, 1996, the additional oilfield service acquisitions  acquired (see Note
2 ) and the increased oil and gas revenues from Odessa Exploration. In addition,
the increase in revenues can be attributed to the  improvement in general market
conditions  in which the Company  operates.  The increase in quarterly  1997 net
income  over the  quarterly  1996 net income is  partially  attributable  to the
acquisition of WellTech and the other recent acquisitions,  but is also a result
of an increase in oilwell service equipment utilization.

Oilfield Services

The Company's  oilfield services  operations are performed  primarily by Yale E.
Key and WellTech Eastern.  Yale E. Key conducts oilfield services in west Texas,
while WellTech Eastern conducts oilfield services in the mid-continent region of
the United States  (primarily  in Oklahoma and East Texas)  through its WellTech
Mid-Continent  Division,  and in the  northeastern  United States  (primarily in
Michigan, Pennsylvania and West Virginia) through its WellTech Eastern Division.
The Company  conducts  oilfield  services in Argentina  through its indirect 63%
ownership in Servicios.

Oilfield service revenues increased  $26,392,000,  or 221%, from $11,916,000 for
the 1996 quarter to $38,308,000  for the 1997 quarter.  The increase in revenues
is primarily  attributable to higher  equipment  utilization as the result of an
increase  in demand  for  oilfield  services  and the  acquisition  of  WellTech
Eastern,  and other smaller recent  acquisitions,  whose  operating  results are
included for the current  quarter but not for the  comparable  1996 quarter.  In
addition,  Yale E. Key diversified oilfield services into higher margin business
segments  such as  oilfield  frac tanks,  oilfield  fishing  tools and  trucking
operations.

                                     - 15 -
<PAGE>

Oilfield service expenses  increased  $17,847,000,  or 206%, from $8,655,000 for
the 1996 quarter to $26,502,000  for the current 1997 quarter.  The increase was
due primarily to the  acquisition  of WellTech on March 26, 1996,  other smaller
recent acquisitions and the increased demand for oilfield services. In addition,
the Company has continued to expand and  diversify  its revenue  base,  offering
ancillary  services  and  equipment  such as  oilwell  fishing  tools,  blow-out
preventors and oilwell frac tanks.

Oil and Natural Gas Exploration and Production

The Company's oil and natural gas  exploration  and  production  operations  are
conducted by Odessa Exploration.  Revenues from oil and gas activities increased
$1,234,000,  or 122%, from $1,016,000 during the quarter ended March 31, 1996 to
$2,250,000 for the current  quarter.  The increase in revenues was primarily the
result of increased production of oil and natural gas as several oil and natural
gas wells which were drilled began production during fiscal 1997, higher oil and
natural gas prices for the  current  year,  and the April 1996  purchase of $6.9
million of oil and gas properties  from an unrelated  third party,  which almost
doubled the number of oil and natural gas wells owned and/or  operated by Odessa
Exploration.

Of the total  $2,250,000  of  revenues  for the quarter  ended  March 31,  1997,
approximately  $1,757,000  was from the sale of oil and gas - 42,604  barrels of
oil at an average  price of $20.26 per barrel and  226,305 MCF of natural gas at
an  average  price  of  $3.95  per  MCF.  The  remaining  $493,000  of  revenues
represented primarily administrative fee income and other miscellaneous income.

Expenses  related to oil and gas activities  increased  $583,000,  or 185%, from
$316,000 for the 1996 quarter to $899,000 for current 1997 quarter. The increase
in expenses was primarily the result of increased  production of oil and natural
gas as several oil and natural gas wells  which were  drilled  began  production
during  1996  and  the  April  1996  purchase  of  $6.9  million  in oil and gas
properties.

Oil and Natural Gas Well Drilling

The  Company's  oil and natural gas well  drilling  operations  are conducted by
Clint Hurt  Drilling.  Oil and  natural  gas well  drilling  revenues  increased
$1,044,000,  or 76%, from  $1,370,000 for the 1996 quarter to $2,414,000 for the
1997  quarter.  The  increase in revenues is  primarily  attributable  to higher
equipment  utilization  and an increase  pricing  structure.  In  addition,  two
drilling rigs were acquired in the March 1996 merger with WellTech.

Expenses  related to oil and  natural  gas well  drilling  activities  increased
$910,000, or 79%, from $1,151,000 for the 1996 quarter to $2,061,000 for current
1997  quarter.  The  increase in expenses is  attributable  to higher  equipment
utilization  and the addition of two drilling rigs as the result of the WellTech
merger.

Interest Expense

Interest expense increased $1,290,000 or 226% to $1,861,000 for the current 1997
quarter  from  $571,000  for the  1996  comparable  quarter.  The  increase  was
primarily  the result of the issuance of $52 million in  principal  amount of 7%
Convertible Subordinated Debentures, (see Note 3).

General and Administrative Expenses

General and  administrative  expenses  are  comprised of the  Company's  and all
subsidiaries  general and  administrative  expenses.  These  expenses  increased
$3,695,000,  or 303%, to $4,914,000 for the current 1997 quarter from $1,219,000
for the comparable 1996 quarter. The increase was primarily  attributable to the
Company's recent acquisitions and expanded services.

                                     - 16 -


<PAGE>

Depreciation, Depletion and Amortization Expense

Depreciation,  depletion and amortization expense increased $2,104,000, or 184%,
to $3,250,000  for the current 1997 quarter from  $1,146,000  for the comparable
1996  quarter.  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  acquisition of WellTech.
In addition,  depletion  expense increased for the period due to the increase in
the production of oil and natural gas.

Income Taxes

Income tax  expense of  $1,207,000  for  current  1997  quarter  increased  from
$399,000 in income tax expense for the comparable 1996 quarter.  The increase in
income taxes is primarily due to the increases in operating income. However, the
Company  does not expect to be  required  to remit a  significant  amount of the
$1,207,000  in total federal  income taxes for fiscal year 1997,  because of the
availability of net operating loss carry-forwards,  accelerated depreciation and
drilling tax credits.

Cash Flow

Net cash provided by operating  activities was $2,414,000 compared to $2,272,000
during the comparable 1996 quarter.  The increase is  attributable  primarily to
increases in net income.

Net  cash  used  in  investing  activities  increased  from  $1,350,000  for the
comparable  1996  quarter to  $13,710,000  for the  current  1997  quarter.  The
increase is primarily the result of increased  capital  expenditures  as well as
the Company's recent acquisitions (see Note 2 to the Financial Statements).

Net cash provided by financing  activities was  $15,480,000 for the current 1997
quarter as compared to $1,426,000  in net cash provided by financing  activities
for the  comparable  1996  quarter.  The increase is primarily the result of the
proceeds from other long-term debt.

NINE  MONTHS ENDED MARCH  31, 1997 VERSUS NINE  MONTHS ENDED MARCH  31, 1996

The Company

Revenues  of the Company  for the nine  months  ended  March 31, 1997  increased
$71,615,000, or 183%, to $110,709,000 from $39,094,000 for the nine months ended
March 31,  1996,  while net income of  $5,962,000  represented  an  increase  of
$3,641,000, or 157%, from the 1996 total of $2,321,000. The increase in revenues
was  primarily  due to increased  oilwell  service  equipment  utilization,  the
acquisition of the WellTech  Eastern  operations from the date of acquisition of
March 26, 1996, the additional oilfield service acquisitions  acquired (see Note
2 ) and the increased oil and gas revenues from Odessa Exploration. In addition,
the increase in revenues can be attributed to the  improvement in general market
conditions in which the Company  operates.  The increase in 1997 net income over
the 1996 net income is partially attributable to the acquisition of WellTech and
the other recent  acquisitions  , but is also a result of an increase in oilwell
service equipment utilization.

Oilfield Services

Oilfield service revenues increased  $66,263,000,  or 213%, from $31,064,000 for
the 1996 period to $97,327,000  for the 1997 nine month period.  The increase in
revenues is primarily attributable to higher equipment utilization as the result
of an increase in demand for oilfield  services and the  acquisition of WellTech
Eastern,  and other smaller  acquisitions,  whose operating results are included
for the current period but not for the comparable 1996 period.

Oilfield service expenses increased  $46,460,000,  or 204%, from $22,808,000 for
the 1996 nine  month  period to  $69,268,000  for the  current  1997  comparable
period.  The increase was due primarily to the  acquisition of WellTech on March
26,  1996,  other  recent  acquisitions  and the  increased  demand for oilfield
services.  In addition,  the Company has  continued to expand and  diversify its
revenue base,  offering ancillary services and equipment such as oilwell fishing
tools, blow-out preventers and oilwell frac tanks.

Oil and Natural Gas Exploration and Production

Revenues  from  oil and gas  activities  increased  $3,120,000,  or  114%,  from
$2,743,000  during the nine months  ended March 31, 1996 to  $5,863,000  for the
current  period.  The increase in revenues was primarily the result of increased
production  of oil and  natural  gas as several  oil and natural gas wells which
were drilled began production during 1997, higher oil and natural gas prices for
the current  year,  and the April 1996  purchase of $6.9  million of oil and gas
properties from an unrelated third party.

Of the total  $5,863,000  of revenues  for the nine months ended March 31, 1997,
approximately  $4,849,000 was from the sale of oil and gas - 109,584  barrels of
oil at an average  price of $22.97 per barrel and  835,918 MCF of natural gas at
an  average  price of $2.79  per  MCF.  The  remaining  $1,014,000  of  revenues
represented primarily administrative fee income and other miscellaneous income.

Expenses  related to oil and gas  activities  increased  $1,250,000 or 134% from
$935,000 for the 1996 nine month period to  $2,185,000  for current 1997 period.
The increase in expenses was primarily the result of increased production of oil
and natural gas as several  oil and natural gas wells which were  drilled  began
production  during 1997 and the April 1996  purchase of $6.9  million in oil and
gas properties.

Oil and Natural Gas Well Drilling

Oil and natural gas well drilling revenues  increased  $2,068,000,  or 41%, from
$5,029,000 for the 1996 nine month period to $7,097,000 for the 1997 period. The
increase in revenues is primarily  attributable to higher equipment  utilization
and an increase pricing structure.  In addition, two drilling rigs were acquired
in the March 1996 merger with WellTech.

Expenses  related to oil and  natural  gas well  drilling  activities  increased
$2,019,000, or 52%, from $3,886,000 for the 1996 nine month period to $5,905,000
for the current 1997 period.  The increase in expenses is attributable to higher
equipment utilization and the addition of two drilling rigs as the result of the
WellTech merger.

Interest Expense

Interest expense  increased  $3,059,000,  or 211%, to $4,507,000 for the current
1997 nine months from  $1,448,000 for the 1996 comparable  period.  The increase
was primarily  the result of the issuance of $52 million in principal  amount of
7% Convertible Subordinated Debentures, (see Note 3).

General and Administrative Expenses

General and  administrative  expenses  are  comprised of the  Company's  and all
subsidiaries  general and  administrative  expenses.  These  expenses  increased
$8,567,000,  or 237%, to $12,176,000 for the current 1997 nine month period from
$3,609,000  for  the  comparable   1996  period.   The  increase  was  primarily
attributable to the Company's recent acquisitions and expanded services.

Depreciation, Depletion and Amortization Expense

Depreciation,  depletion and amortization expense increased $4,747,000, or 161%,
to  $7,687,000  for the current 1997 nine month period from  $2,940,000  for the
comparable  1996  period.  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 acquisition
of WellTech. In addition,  depletion expense increased for the period due to the
increase in the production of oil and natural gas.

Income Taxes

Income tax expense of  $3,020,000  for current 1997 nine month period  increased
from  $1,129,000  in income tax  expense for the  comparable  1996  period.  The
increase in income taxes is primarily due to the increases in operating  income.
However,  the  Company  does not expect to be  required  to remit a  significant
amount of the  $3,020,000  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  $977,000 from  $5,318,000
during the comparable  1996 nine month period to $4,341,000 for the current 1997
period.  The  decrease  is  attributable  primarily  to an  increase in accounts
receivable and a decrease in accounts payable and accrued expenses.

Net  cash  used  in  investing  activities  increased  from  $5,594,000  for the
comparable  1996 nine month period to  $34,775,000  for the current 1997 period.
The increase is primarily the result of increased capital  expenditures and cash
paid for  oilwell  service  acquisitions  (see  Note  2).  These  increases  are
partially offset by a decrease in expenditures for oil and gas properties.

Net cash provided by financing  activities was  $41,319,000 for the current 1997
nine month period as compared to  $2,304,000  in net cash  provided by financing
activities for the comparable 1996 period.  The increase is primarily the result
of the  proceeds  from the issuance of the  Company's 7% debenture  and proceeds
from other long-term debt.

LIQUIDITY AND CAPITAL RESOURCES

At March 31, 1997, the Company had $11,528,000 in cash as compared to $3,240,000
in cash at June 30, 1996.

The Company has projected $12 million for oilfield service capital  expenditures
for fiscal  1997,  (revised  since  December  31,  1996 due to  oilwell  service
acquisitions),  as compared to $5.2  million for fiscal 1996.  Oilfield  service
capital  expenditures  for the nine months  ended March 31, 1997 of $9.1 million
are expected to be primarily capitalized improvement costs to existing equipment
and  machinery.  The  Company  expects to  finance  these  capital  expenditures
utilizing the operating cash flows of the Company.

Odessa  Exploration  is  forecasting  outlays of  approximately  $6.0 million in
development  costs for fiscal 1997,  as compared to $9.8 million  during  fiscal
1996.  Financing is expected to come from  borrowings  under its Norwest  credit
facilities.

Clint Hurt  Drilling  has  forecast  approximately  $1.5 million for oil and gas
drilling  capital  expenditures  for fiscal 1997 primarily for  improvements  to
existing  equipment  and  machinery  compared to $598,000 for fiscal 1996.  Such
outlays  are  treated as  capital  costs.  Financing  is  expected  to come from
existing cash flow.

Debt

Recent Development

On April 7, 1997, the Company announced that it had entered into an agreement by
which Lehman  Commercial Paper, Inc. would provide (or arrange to be provided) a
$225 million credit facility,  consisting of a $100 million seven-year term loan
and a $125 million five-year revolver. The floating interest rate is expected to
be lower than the Company's  current rate on its existing bank debt. The Company
intends to use 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.  The credit  facility is expected to
be in place before June 30, 1997. 

Other Debt

In  July  1996,  the  Company  completed  the  offering  of  $52,000,000  of  7%
convertible  subordinated  debentures  due  2003.  The  Offering  was a  private
offering  pursuant  to Rule 144A under the  Securities  Act.  Proceeds  from the
Offering were  approximately  $52,000,000 and were used to  substantially  repay
existing long-term debt  (approximately  $35.4 million).  The remaining proceeds
were used to fund the expansion of the Company's operations through acquisitions
of businesses and assets, for working capital and general corporate purposes.

The  Company's  long-term  debt that was repaid with  proceeds from the Offering
consisted  of (i)  indebtedness  under  the term  notes  with  CIT  Group/Credit
Finance,  Inc.  ("CIT")  aggregating  approximately  $21.2  million and (ii) all
indebtedness owed by Odessa Exploration to Norwest Bank Texas, N.A.  ("Norwest")
totaling approximately $14.2 million.

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

                                     - 20 -


<PAGE>

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.

The  Debentures  are not  redeemable  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 Debenture  prospectus,
together with accrued and unpaid  interest  thereon.  The Debentures also may be
redeemed at the option of the holder if there is a change in control (as defined
in the  original  Debenture  prospectus)  at 100%  of  their  principal  amount,
together with accrued and unpaid interest thereon.

Pursuant to the terms of the  Indenture  governing  the rights of the holders of
the  Offering,  the Company was required to obtain  Servicios'  guarantee of the
Company's  indebtedness  under the  offering and agreed to increase the interest
rate  payable on the  offering  to 7 1/2 % in the event such  guarantee  was not
obtained.  To date, such guarantee has not been obtained,  and,  therefore,  the
Offering is currently  accruing  interest at a rate of 7 1/2%.  The Company made
its first interest payment on December 31, 1996.

In March 1997, the Company completed the re-negotiation of its credit facilities
with CIT  consisting  of a line of  credit  and term  loan for each of  WellTech
Eastern,  Yale E.  Key  and  Clint  Hurt.  The  re-negotiated  term  and  credit
facilities  include  a  maximum  credit  availability  of the  lesser of (i) $55
million,  or (ii) an amount  subject to certain asset  valuations  determined by
CIT. Also, the re-negotiated term and credit facilities include an interest rate
at one-quarter percent above the stated prime rate, which was 8.25% at March 31,
1997.

In  addition to the CIT credit  facilities,  Odessa  Exploration  has funded its
operations and acquisitions in part through a credit facility with Norwest.  All
amounts  previously owed by Odessa  Exploration  under the Norwest facility were
paid using a portion of the proceeds  from the Offering.  Effective  January 31,
1997,  Odessa  Exploration  completed the  re-negotiation  of the Norwest credit
facility,  which,  among  other  things,  increased  its  borrowing  base to $18
million, of which $1.2 million had been advanced as of March 31, 1997.

Impact of SFAS 121

In March 1995,  the Financial  Accounting  Standards  Board issued  Statement of
Financial  Accounting  Standards No. 121 - Accounting for Long-Lived  Assets and
for Long-Lived Assets to be Disposed Of ("SFAS 121") regarding the impairment of
long-lived  assets,  identifiable  intangibles  and  goodwill  related  to those
assets.  The application of SFAS 121 requires periodic  determination of whether
the book value of long-lived  assets  exceeds the future cash flows  expected to
result from the use of such assets and,  if so, will  require  reduction  of the
carrying  amount of the "impaired"  assets to their  estimated fair values.  The
Company implemented SFAS 121 beginning July 1, 1996, (see Note 4).

Impact of Inflation on Operations

Although  in our  complex  environment  it is  extremely  difficult  to  make an
accurate  assessment  of the impact of  inflation on the  Company's  operations,
management is of the opinion that inflation has not had a significant  impact on
its business.

Internal  Revenue  Service of the 1991 federal income tax returns of Cobra,  the

proprietary  data  and the  goodwill  associated  therewith  (collectively,  the
AIntellectual  Property@)  that are either  material to its business or that are
necessary for the  rendering of any services  rendered by it and the use or sale
of any equipment or products used or sold by it, including all such Intellectual
Property listed in Schedule 2.1.12 hereto. The Intellectual Property so owned or
possessed by Cobra is owned or licensed free and clear of any Encumbrance. Cobra
has not  granted  to any  other  person  any  license  to use  any  Intellectual
Property.  Cobra has not received any notice of infringement,  misappropriation,
or conflict with, the intellectual  property rights of others in connection with
the use by it of the  Intellectual  Property or otherwise in connection with the
operation of its business.  2.1.13.  Title to and Condition of Assets. Cobra has
good,  indefeasible  and marketable  title to all its  properties,  interests in
properties  and assets,  real and personal,  reflected in the Unaudited  Balance
Sheet or in Schedule 2.1.8 hereto, free and clear of any Encumbrance, except (i)
Encumbrances  reflected  in the  Unaudited  Balance  Sheet or in Schedule  2.1.8
hereto,  (ii) liens for current  taxes not yet due and  payable,  and (iii) such
imperfections  of  title,  easements  and  Encumbrances,  if  any,  as  are  not
substantial in character,  amount,  or extent and do not and will not materially
detract  from the value,  or  interfere  with the present  use, of the  property
subject thereto or affected  thereby,  or otherwise  materially  impair business
operations.  All leases  pursuant  to which Cobra  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 Cobra and in respect to which Cobra
has not taken adequate steps to prevent a default from occurring.  The buildings
and  premises  of  Cobra  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 Cobra 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.  All such assets conform in all material respects
to all applicable  laws  governing  their use. No notice of any violation of any
law, statute,  ordinance, or regulation relating to any such assets has been (or
are being)  received  by Cobra or any of the  Shareholders,  except such as have
been fully complied with. 2.1.14.  Contracts.  All contracts,  leases,  plans or
other  arrangements  to which Cobra is a party, by which it is bound or to which
Cobra or the  assets of Cobra are  subject  are in full  force and  effect,  and
constitute  valid and binding  obligations  of Cobra.  Cobra 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 material  default  thereunder.  No contract has
been  entered  into on  terms  which  could  reasonably  be  expected  to have a
materially adverse effect on Cobra. Neither of the Shareholders has received any
information  which would cause such Shareholder to conclude that any customer of
Cobra will (or is likely to) cease doing  business with Cobra (or any successors
thereto)  as a  result  of the  consummation  of the  transactions  contemplated
hereby. 2.1.15. Licenses and Permits. Cobra possess all permits, authorizations,
certificates,   approvals,   registrations,   variances,   waivers,  exemptions,
rights-of-way,  franchises,  ordinances, licenses and other rights of every kind
and character (collectively, the APermits@) necessary under law or otherwise for
it to  conduct  its  business  as now being  conducted  and to  construct,  own,
operate,  maintain  and use its assets in the manner in which they are now being
constructed,  operated, maintained and used. Each of such Permits and the rights
of Cobra with respect thereto is (and will be following the  consummation of the
transactions  contemplated  hereby)  valid  and  subsisting,  in full  force and
effect, and enforceable by Cobra subject to administrative  powers of regulatory
agencies having  jurisdiction.  Cobra is in compliance in all material  respects
with the  terms of such  Permits.  None of such  Permits  have  been,  or to the
knowledge  of  the  Shareholders,  are  threatened  to  be,  revoked,  canceled,
suspended  or  modified.  2.1.16.  Litigation.  Except as set forth on  Schedule
2.1.16,  there is no suit,  action, or legal,  administrative,  arbitration,  or
other proceeding or governmental investigation pending to which Cobra is a party
or,  to the  knowledge  of the  Shareholders,  might  become  a party  or  which
particularly  affect  Cobra,  nor  is  any  change  in the  zoning  or  building
ordinances directly affecting the real property or leasehold interests of Cobra,
pending  or,  to  the  knowledge  of  the  Shareholders,   threatened.   2.1.17.
Environmental Compliance.

2.1.17.1  Environmental  Conditions.
Except as set  forth in  Schedule  2.1.17  hereof,  there  are no  environmental
conditions or  circumstances,  including,  without  limitation,  the presence or
release of any  hazardous  substance,  on any property  presently or  previously
owned by  Cobra,  or on any  property  to which  hazardous  substances  or waste
generated by the  operations  of Cobra or by the use of the assets of Cobra were
disposed of, which would result in a material  adverse change in the business or
business prospects of Cobra. The term Ahazardous  substance@ means (i) asbestos,
polychlorinated  biphenyls,  urea  formaldehyde,  lead based  paint,  radon gas,
petroleum,  oil,  solid  waste,  pollutants  and  contaminants,   and  (ii)  any
chemicals,   materials,  wastes  or  substances  that  are  defined,  regulated,

Laws,   including,   but  not  limited  to,  substances  defined  as  Ahazardous
substances,@  Ahazardous materials,@ or Ahazardous waste@ in CERCLA, RCRA, HMTA,
or  comparable  state and  local  statutes  or in the  regulations  adopted  and
promulgated pursuant to said statutes;  2.1.17.2 Permits, etc. Cobra has in full
force and  effect  all  environmental  permits,  licenses,  approvals  and other
authorizations required to conduct its operations, other than those that are not
material  to its  business  or  operations,  and  is  operating  in  substantial
compliance thereunder;  2.1.17.3 Compliance. Neither the operations of Cobra nor
the use of the assets of Cobra  violate in any respect any  applicable  federal,
state or local  law,  statute,  ordinance,  rule,  regulation,  order or  notice
requirement  pertaining to (a) the condition or protection of air,  groundwater,
surface  water,  soil,  or  other  environmental  media,  (b)  the  environment,
including  natural  resources or any activity which affects the environment,  or
(c)  the  regulation  of any  pollutants,  contaminants,  waste,  or  substances

satisfactory to Key that an exemption from registration is available;

2.2.6.   Investor  Sophistication.

Such  Shareholder  has had the  opportunity  to ask  questions  of, and  receive

Key and the Key Shares, to the extent Key=s officers and directors possessed the
same or could  acquire  it  without  unreasonable  effort  or  expense,  as such
Shareholder  deemed  necessary in connection with making an informed  investment
decision; and

2.2.8.   Restrictive  Legends.
In addition to any other legends required by law or the other agreements entered
into in connection  herewith,  each  certificate  evidencing the Key Shares will
bear a conspicuous  restrictive legend  substantially as follows: THE SECURITIES

IN ACCORDANCE WITH THE REGISTRATION REQUIREMENTS OF THE ACT AND SUCH OTHER STATE

AVAILABLE.

                                    ARTICLE 3
                      Representations and Warranties of Key

         Key represents and warrants to each of the Shareholders as follows:

3.1.  Organization  and Standing.
Key is a corporation duly organized, validly existing and in good standing under
the laws of the  State of  Maryland,  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  where  the  failure  to  be so
qualified or licensed would not have a material  adverse effect on its financial
condition, properties or business.

3.2. Agreement Authorized and its Effect on Other Obligations.  The consummation
of the transactions contemplated hereby have been duly and validly authorized by
all necessary corporate action on the part of Key, and this Agreement is a valid
and  binding  obligation  of  Key  enforceable   (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
performance  of this  Agreement  by Key will not  conflict  with or  result in a
violation or breach of any term or provision  of, or  constitute a default under
(i) the  Articles  of  Incorporation  or Bylaws  of Key or (ii) any  obligation,
indenture,  mortgage, deed of trust, lease, contract or other agreement to which
Key or any of its property is bound.

3.3.  Capitalization.
The  capitalization of Key consists of 25,000,000 shares of Key Common Stock, of
which as of the date  hereof,  11,398,050  shares are  issued  and  outstanding,
913,334  shares are  reserved for issuance  pursuant to stock  options,  825,000

without  further  shareholder  action,  to redesignate all of the authorized and
unissued shares of Key Common Stock into one or more series of preferred  stock.

basis during the periods involved and fairly present the consolidated  financial
position of Key and its  consolidated  subsidiaries  as of the dates thereof and
the consolidated  results of their operations and changes in financial  position
for the periods then ended; and the Key SEC Documents did not contain any untrue
statement  of a material  fact or omit to state a material  fact  required to be
stated therein or necessary to make the statements  therein, in the light of the
circumstances  under which they were, made not misleading.  Since June 30, 1994,

applicable  rule,  regulation,  or  any  writ  or  decree  of any  court  or any
governmental   commission,   board,  bureau,  agency,  or  instrumentality,   or
delinquent with respect to any report required to be filed with any governmental
commission, board, bureau, agency or instrumentality which would have a material
adverse affect upon its financial condition, properties or business.

suit or  proceeding  pending  or,  to the  best of Key=s  knowledge,  threatened
against or affecting Key by any federal,  state, municipal or other governmental
department,  commission, board, bureau, agency or instrumentality,  which either
individually  or in the  aggregate,  does or is likely to result in any material
adverse change in the financial condition, properties or businesses of Key.

3.9.  Finder=s Fee.
All negotiations  relative to this Agreement and the  transactions  contemplated
hereby have been carried on by Key and its counsel  directly  with Cobra and the
Shareholders and their counsel,  without the intervention by any other person as

against any of the parties hereto for any brokerage commission,  finder=s fee or
any similar payments.

3.10.  Key=s Access to Cobra=s  Assets and Records.
Key  acknowledges  that it is actively engaged in the same business as is Cobra,
that it has been  afforded an  opportunity  to examine the assets and records of
Cobra,  discuss  Cobra=s  business and  operations  with the  Shareholders,  and
investigate the condition of the assets of Cobra,  and that Key is entering into
this Agreement on the basis of such  investigation and the  representations  and

                                    ARTICLE 4
                        Obligations Pending Closing Date

4.1.  Agreements  of Key and  the  Shareholders.
Except  as  expressly  contemplated  elsewhere  in this  Agreement,  Key and the
Shareholders  agree that from the date hereof until the Closing Date,  Key will,
and the Shareholders will cause Cobra to (and unless otherwise  indicated by the
context, since September 30, 1996, it has):

4.1.1.  Maintenance of Present  Business.
Operate its business only in the usual,  regular,  and ordinary  manner so as to
maintain  the  goodwill it now enjoys and,  to the extent  consistent  with such
operation,  use all reasonable  efforts to preserve intact its present  business
organization, keep available the services of its present officers and employees,
and preserve its relationships with customers, suppliers, jobbers, distributors,
and others having business dealings with it;

4.1.2.  Maintenance  of  Properties.
At its expense,  maintain  all of its  property and assets in customary  repair,
order, and condition, reasonable wear and tear excepted;

4.1.3.  Maintenance  of Books and  Records.
Maintain  its books of account and records in the usual,  regular,  and ordinary
manner, in accordance with generally accepted accounting principles applied on a
consistent basis;

4.1.4.  Compliance with  Law.
Duly comply in all material  respects with all laws  applicable to it and to the
conduct of its business;

4.1.5.   Inspection.
Permit the other  party  hereto  and their  authorized  representatives,  during
normal  business hours, to inspect its records and to consult with its officers,
employees,  attorneys, and agents for the purpose of determining the accuracy of
the representations and warranties herein made and the compliance with covenants
contained in this Agreement.  Each of the  Shareholders and Key agrees that they
will and  will  cause  their  representatives  to hold all data and  information
obtained with respect to the other party,  in confidence and further agrees that
they will not use such  data or  information  or  disclose  the same to  others,
except to the extent such data or information  either are, or become,  published
or a matter of public knowledge through the fault of its own; and

4.1.6.  Notice of Material  Developments.
Promptly notify the other party in writing of any Amaterial  adverse change@ in,
or any changes  which,  in the  aggregate,  could result in a Amaterial  adverse
change@ in, the consolidated  financial  condition,  business or affairs of such
party,  whether or not occurring in the ordinary course of business.  As used in
this  Agreement,  the term Amaterial  adverse  change@ means any change,  event,
circumstance or condition (collectively,  a AChange@) which when considered with
all other Changes would  reasonably be expected to result in a "loss" having the
effect  of so  fundamentally  adversely  affecting  the  business  or  financial
prospects  of Key or Cobra,  as the case may be,  that the  benefits  reasonably
expected to be obtained by Key or Cobra,  as the case may be, as a result of the
consummation  of the  transactions  contemplated  by  this  Agreement  would  be
jeopardized  with  relative  certainty.  The term "loss"  shall mean any and all
direct or indirect payments, obligations,  assessments,  losses, loss of income,
liabilities,  fines,  penalties,  costs and  expenses  paid or  incurred or more
likely than not to be paid or incurred,  or  diminutions in value of any kind or
character  (whether known or unknown,  conditional or  unconditional,  choate or
inchoate,  liquidated or unliquidated,  secured or unsecured, accrued, absolute,
contingent  or  otherwise)  that are more  likely  than not to occur,  including
without limitation penalties, interest on any amount payable to a third party as
a result of the foregoing and any legal or other expenses reasonably incurred or
more  likely  than  not to be  incurred  in  connection  with  investigating  or
defending  any demands,  claims,  actions or causes of action that, if adversely
determined, would likely result in losses, and all amounts paid in settlement of
claims or actions; provided, that losses shall be net of any recoveries by Cobra
from third parties and any insurance  proceeds Cobra is entitled to receive from
a nonaffiliated  insurance  company on account of such losses (after taking into
account any costs  incurred  in  obtaining  such  proceeds  and any  increase in
insurance  premiums as a result of a claim with respect to such  proceeds);  and
provided further,  that a reduction of the trading price of the Key Common Stock
on the  American  Stock  Exchange  shall  not,  in and of itself,  constitute  a
material adverse change.

4.2.  Additional  Agreements  of the  Shareholders.
Except  as  expressly  contemplated  elsewhere  in this  Agreement,  each of the
Shareholders  agree that since the Balance  Sheet Date,  Cobra has not, and from

as is otherwise approved in writing by Key;

Sell, dispose of, or encumber,  any property or assets,  except (i) in the usual

a value of less than $1,000; or (iii) as may be approved in writing by Key;

4.2.5.  Maintenance  of  Insurance.
Discontinue its current level of insurance;  provided, that if during the period
from the date hereof to and  including  the Closing  Date any of its property or
assets are damaged or destroyed by fire or other  casualty,  the  obligations of
Key and the Shareholders under this Agreement shall not be affected thereby, and
upon the Closing Date all proceeds of insurance and claims of every kind arising
as a result of any such  damage or  destruction  shall  remain the  property  of
Cobra;  4.2.6.  Acquisition  Proposals.  Directly  or  indirectly  (i)  solicit,
initiate or encourage  any inquiry or  Acquisition  Proposal  from any person or

or agents;

contract or commitment  to issue or sell (upon  conversion  or  otherwise),  any
shares of Cobra Common Stock,  or subdivide or in any way  reclassify any shares
of Cobra  Common  Stock,  or acquire,  or agree to acquire,  any shares of Cobra
Common Stock; and

4.2.9.  Prohibition  on  Dividends.

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
Damages arising under this Article 8 may be made, 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,

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,  and the  expenses  of  such  defense  shall  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.

into on terms which  could  reasonably  be  expected to have a material  adverse
effect on the use of the Assets by Buyer. Neither Seller nor the Shareholder has
received  any  information  which would  cause such party to  conclude  that any

infringe,  misappropriate  or conflict with the intellectual  property rights of
others.   Neither  Seller  nor  the  Shareholder  has  received  any  notice  of
infringement,  misappropriation,  or  conflict  with the  intellectual  property
rights of others in connection with the use by Seller of the Seller Intellectual
Property.

materially  adversely  effect the profitable use of the Assets or conduct of the

policies,  lists of suppliers and customers, and 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  the
Shareholder and delivered to Buyer or Key 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 Shareholder
and their  counsel  directly  with  Buyer,  Key and their  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.

2.1.16.  Investment  Representations of Seller. Pursuant to Sections 1.2 and 4.2
hereof,  Key will issue the Key shares to the  Shareholder.  In connection  with
this issuance, each of Seller and the Shareholder  acknowledges,  represents and
agrees that :

(a) The  Shareholder  is an  "accredited  investor"  as such term is  defined in
Regulation  D under the  Securities  Act of 1933,  as amended  (the  "Securities
Act").

(b)(i)  The  Shareholder,  through  his  own  operations,  is  knowledgeable  in
operations of the type  conducted by Key, (ii) Key has made  available to Seller
and the Shareholder  extensive legal,  financial,  accounting and other business
records for  examination by Seller and the  Shareholder,  (iii) Key has made its
principal  executive and operating personnel available for consultation with the
designated  representatives  of Seller and the Shareholder,  (iv) Seller and the
Shareholder   have  made  an  extensive   investigation   of  Key's  assets  and
liabilities, business and financial affairs, and operations, (v) the Shareholder
is aware of the risks  associated  with  ownership  of the Key Shares,  (vi) the
Shareholder  is capable of bearing  the  financial  risks  associated  with such
ownership,  and (vii) while  recognizing  that he cannot  effectively  waive the
protections  afforded to it under the Securities  Act, he regards  himself as an
entity of such financial capacity, sophistication, and prudence that he does not
require the  protections  afforded to him by the Securities  Act, and is relying
upon his own  investigation  of Key in making  his  decision  to enter into this
Agreement.

(c) The Key  Shares  have not been  registered  under  the  Securities  Act,  or
registered or qualified under any applicable state securities laws;

(d) The Key  Shares  are  being  issued  to the  Shareholder  in  reliance  upon
exemptions  from  such  registration  or  qualification  requirements,  and  the
availability of such exemptions depends in part upon the Shareholder's bona fide
investment intent with respect to the Key Shares;

(e)  Seller's  acquisition  of the Key Shares is solely for its own  account for
investment,  and Seller is not  acquiring  the Key Shares for the account of any
other person or with a view toward  resale,  assignment,  fractionalization,  or
distribution thereof;

(f) Seller shall not offer for sale,  sell,  transfer,  pledge,  hypothecate  or
otherwise  dispose  of any of the Key  Shares  except  in  accordance  with  the
registration  requirements of the Securities Act and applicable state securities
laws  or  upon  delivery  to Key  of an  opinion  of  legal  counsel  reasonably
satisfactory to Key that an exemption from registration is available;

(g) Since the Key Shares have not been  registered  under the  Securities Act or
applicable state securities laws,  Seller must bear the economic risk of holding
the Key  Shares  for an  indefinite  period of time,  and  Seller is  capable of
bearing such risk; and

(h) In addition  to any other  legends  required by law or the other  agreements
entered into in connection herewith,  the certificate  evidencing the Key Shares
will bear a conspicuous restrictive legend substantially as follows:

THE SECURITIES  EVIDENCED  HEREBY HAVE NOT BEEN REGISTERED  UNDER THE SECURITIES
ACT OF 1933, AS AMENDED ("ACT"),  OR UNDER ANY APPLICABLE STATE SECURITIES LAWS,
AND THEY CANNOT BE OFFERED FOR SALE,  SOLD,  TRANSFERRED,  PLEDGED OR  OTHERWISE
HYPOTHECATED EXCEPT IN ACCORDANCE WITH THE REGISTRATION  REQUIREMENTS OF THE ACT
AND SUCH OTHER STATE LAWS OR UPON DELIVERY TO THIS  CORPORATION OF AN OPINION OF
LEGAL  COUNSEL   SATISFACTORY  TO  THE   CORPORATION   THAT  AN  EXEMPTION  FROM
REGISTRATION IS AVAILABLE.

2.2.  Limitation  on   Representations.   The  existence  of  an  inaccuracy  or
incorrectness  with  respect to a  representation  contained  in this Article II
shall not constitute a misrepresentation  or a breach of any such representation
unless such  inaccuracy  or  incorrectness  shall be material.  An inaccuracy or
incorrectness shall be considered material if:

(a) it is contained in a financial  statement delivered by Seller to Buyer prior
to Closing and relates to a financial  matter which could reasonably be expected
to be  relied  on by Buyer  in  determining  the  advisability  of the  purchase
described herein or the amount of consideration to be paid; or,

(b) it results in an actual financial loss to Buyer.

2.3 To the  Knowledge  of Seller.  The term "to  Seller's  or the  Shareholder's
knowledge" or any similar term, where any  representation or warranty  contained
in Article II is expressly  qualified  by  reference to such phrase,  shall mean
that Seller acting by and through its duly  appointed and  authorized  officers,
confirms that as to the matters that are the subject of such representations and
warranties,  such officers either have actual  knowledge of such matters or have
made inquiries with respect to such matters,  sufficient to allow Seller to make
such representation or warranty in good faith without actual knowledge that such
representation is untrue.

indenture,  mortgage, deed of trust, lease, contract or other agreement to which
Buyer is a party or by which  Buyer or its  properties  are bound;  or (iii) any
provision of any law,  rule,  regulation,  order,  permits,  certificate,  writ,
judgment,  injunction,  decree,  determination,  award or other  decision of any
court,  arbitrator or other governmental  authority to which Buyer or any of its
properties is subject.

transactions  contemplated  hereby have been carried on by Buyer and its counsel

3.2 Representations and Warranties of Key. Key represents and warrants to Seller
and the Shareholder as follows:

3.2.1.  Organization and Standing. Key is a corporation duly organized,  validly
existing and in good standing under the laws of the State of Maryland,  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
where the failure to so qualify or be licensed would not have a material adverse
effect on the business of Buyer.

3.2.2.  Agreement Authorized and its Effect on Other Obligations.  The execution
and  delivery of this  Agreement  and all other  agreements  executed by Key and
delivered  to  Seller,  or the  Shareholder  in  connection  herewith  (the "Key
Agreements") have been authorized by all necessary  corporate action on the part
of Key,  and  this  Agreement  and the Key  Agreements  are  valid  and  binding
obligations of Key, enforceable (subject to normal equitable principals) against
Key in accordance with their 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 performance of
this Agreement and the Key Agreements and the  consummation of the  transactions
contemplated  hereby and thereby will not conflict with or result in a violation
or breach of any term or provision  of, nor  constitute a default  under (i) the
charter or bylaws of Key;  (ii) any  obligation,  indenture,  mortgage,  deed of
trust,  lease,  contract or other  agreement to which Key is a party or by which
Key or its  properties  are  bound;  or (iii) any  provision  of any law,  rule,
regulation, order, permits,  certificate,  writ, judgment,  injunction,  decree,
determination,  award  or  other  decision  of any  court,  arbitrator  or other
governmental authority to which Key or any of its properties is subject.

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

                                   Article IV

                              Additional Agreements

4.1  Noncompetition.  Except as otherwise consented to or approved in writing by
Buyer and Key, each of Seller and the Shareholder agrees that for a period of 60
months following the Effective Date, directly or indirectly,  acting alone or as
a member of a  partnership  or a 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 business selling and installing wellhead and down hole equipment,  providing
drilling,  workover  or well  services,  engaging in oil field tool  rental,  or
providing any other oil field services  previously provided by Seller during the
twenty-four  (24) month period in Texas,  Oklahoma or Kansas (the  "Territory");
(ii)  request any present  customers or suppliers of Seller to curtail or cancel
their  business  with  Buyer  or Key;  (iii)  disclose  to any  person,  firm or
corporation any trade,  technical or technological  secrets of Seller,  Buyer or
Key or any details of their  organization or business  affairs or (iv) induce or
actively  attempt to influence  any  employee of Buyer or Key to  terminate  his
employment. Seller agrees that if either the length of time or geographical area
of the Territory 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 4.1 are in addition to
any other  obligations that Seller or the Shareholder may have under the laws of
any state requiring a corporation who sells its assets (and the  shareholders of
such  corporation)  to limit its  activities  so that the  goodwill and business
relations being  transferred  with such assets will not be materially  impaired.
Seller  further  agrees  and  acknowledge  that  Buyer  and Key do not  have any
adequate  remedy at law for the  breach or  threatened  breach by Seller of this
covenant,  and agree that Buyer or Key may, in  addition  to the other  remedies
which may be available to them hereunder, file a suit in equity to enjoin Seller
from such breach or threatened breach. If any provisions of this Section 4.1 are
held to be invalid or against public policy, the remaining  provisions shall not
be affected  thereby.  Seller  acknowledges that the covenants set forth in this
Section 4.1 are being executed and delivered by Seller in  consideration  of the
covenants of Buyer and Key contained in this  Agreement,  and for other good and
valuable consideration, receipt of which is hereby acknowledged.

4.2  Issuance of Key Shares.  On the date hereof,  Key shall file an  additional
listing  application with the American Stock Exchange  requesting the listing of
the Key Shares. On the date Key receives notice of approval of such request, Key
shall send written  instructions  to its transfer  agent and registrar to issue,
countersign and register one or more certificates representing the Key Shares in
the name of the Shareholder and deliver such  certificate(s)  to the Shareholder
at the address  specified in Section 6.4 hereof.  In the event that the American
Stock  Exchange  does not approve the listing  application,  the parties  hereto
shall  negotiate  in good faith the  appropriate  consideration  to replace such
shares.

4.3 Employment of the Shareholder. Buyer hereby agrees to employ the Shareholder
as Buyer's  area  manager at a salary of $5,000  per  month,  a monthly  vehicle
allowance  and  those  additional   benefits  now  afforded  buyer's   employees
commensurate  with  shareholder's  area manager  position with Buyer. 4.4 Hiring
Employees.  Effective  as of the  date  hereof,  all of the  Employees  shall be
terminated by Seller.  Buyer may, but shall be under no obligation  to, hire any
of the Employees effective as of the date hereof.  Except as provided in Section
1.4 hereof,  Buyer shall have no  liability  or  obligation  with respect to any
employee  benefits of any Employee except those benefits that accrue pursuant to
such Employees'  employment  with Buyer on or after the date hereof.  Seller and
the  Shareholder  shall  cooperate  with Buyer in  connection  with any offer of
employment  from Buyer to the  Employees  and use its best  efforts to cause the
acceptance  of any and all such offers.  All  Employees  hired by Buyer shall be
at-will employees of Buyer.

4.5  Registration  Rights.  Key has  delivered to the  Shareholder a copy of the
Registration Right Agreement among Key, McMahan Securities Co. L.P. and Rauscher
Pierce Refsnes,  Inc. dated July 3, 1996 (the  "Registration  Rights Agreement")
pursuant  to which Key has  agreed  to (i) file a  registration  statement  (the
"Shelf  Registration  Statement")  with  the  SEC on or  before  April  3,  1997
registering  the resale of  certain  shares of Key Common  Stock  issuable  upon
conversion of certain outstanding convertible debentures of Key and (ii) use its
best efforts to cause the Shelf Registration  Statement to be declared effective
by the SEC on or before July 3, 1997. Key hereby agrees to include the resale of
the Key Shares in the Shelf Registration  Statement;  provided, that (i) each of
the  Shareholders  shall have all duties and obligations of a "Holder" under the
Registration  Rights  Agreement and (ii),  notwithstanding  the inclusion of the
resale of the Key Shares in the Shelf Registration  Statement,  the Shareholders
shall have no right to participate in an underwritten  offering,  if any, of Key
Common  Stock by those  debenture  holders  exercising  their  rights  under the
Registration  Rights  Agreement.  In  the  event  that  the  Shelf  Registration
Statement  is  declared  effective  by July 3, 1997,  Key shall,  subject to the
"Black-out"  provision in Section 4(b)(i) of the Registration  Rights Agreement,
use its best  efforts to keep such  Shelf  Registration  Statement  continuously
effective,  supplemented  and  amended as required  to the extent  necessary  to
ensure that it is  available  for resale of the Key Shares and to insure that it
conforms with the Securities Act and the policies,  rules and regulations of the
commission  as announced  from time to time,  for a period of at least three (3)
years  following  the date of issuance of the Key Shares or such shorter  period
that will  terminate  when all of the Key Shares have been sold  pursuant to the
Shelf Registration  Statement or pursuant rule 144 of the Securities Act. If Key
shall fail to keep such  registration  statement so  effective,  then during any
period  prior  to the  date  termination  is  allowed  during  which  the  Shelf
Registration  Statement  is not  effective  in  accordance  with  the  foregoing
provision,  Seller or Shareholder  shall have a Put Right to the same extent and
exercisable in the same manner as provided in the following sentence relating to
the Put Right  available  during the period July 3, 1997 through August 3, 1997,
in the event the Shelf Registration Statement does not become effective.  In the
event that the Shelf Registration Statement is not declared effective by the SEC
by July 3, 1997, Seller shall have the right (the "Put Right") to require Key to
purchase  the Key Shares from Seller for an  aggregate  purchase  price equal to
ninety- percent (90%) of the aggregate market value of the Key Shares calculated
using the per share  closing  price on July 3, 1997 as reported by the  American
Stock  Exchange.  The Put Right shall be exercised by delivery of written notice
to Key on or before August 3, 1997, after which date the Put Right shall expire.
During any period in which Seller or Shareholders  holds a Put Right pursuant to
this  Section  4.5,  such Put  Right  may be  exercised  as often as  Seller  or
Shareholder  desires and such Put Right may be exercised  with respect to all or
such portion of the Key Shares as Seller or Shareholder  may desire.  The rights
of Seller set forth in this paragraph  shall be  transferable to Shareholder but
not otherwise.  To the extent shares have been  transferred to Shareholder,  the
term Seller shall include shareholder.

4.6  Allocation  of Purchase  Price.  The parties  hereto  agree to allocate the
purchase  price paid by Buyer for the Assets  hereunder as set forth on Schedule
4.6 hereto, and shall report this transaction for federal income tax purposes in
accordance with the allocation so agreed upon. The parties hereto for themselves
and for their  respective  successors  and assigns  covenant and agree that they
will file  coordinating  Form  8594's in  accordance  with  Section  1060 of the
Internal  Revenue Code of 1986,  as amended,  with their  respective  income tax
returns for the taxable year that includes the date hereof.

4.7 Name Change.  Seller and the Shareholder shall, within thirty (30) days from
the date hereof,  caused to be filed (i) with the secretary of state of Seller's
state  of  organization  an  amendment  to  the  charter  (or  other  applicable
organization  document)  of Seller  changing the name of Seller from its current
name to a name that is not  similar to such name or such  documents  required to
effect the  dissolution  of Seller so that the separate  corporate  existence of
Seller is  terminated,  and (ii) with the  appropriate  authorities  of Seller's
state of  organization  and any other  states such  documents as are required to
effect such name change or dissolution, including without limitation, amendments
or  withdrawals  of  certificates  of  authority to do business and assumed name
filing. Seller and the Shareholder shall, within five (5) business days from the
date of its receipt of  confirmation  of such filings from the applicable  state
authorities, cause to be delivered to Buyer copies of all such confirmations.

4.8 Collection of  Receivables.  Buyer shall cooperate with and assist Seller in
collecting  the Seller  Receivables,  which  cooperation  and  assistance  shall
include  promptly  forwarding to Seller all payments  received by Buyer that are
made in respect of the  Seller  Receivables.  Seller  shall  cooperate  with and
assist  Buyer  in  collecting   receivables  of  Buyer,  which  cooperation  and
assistance shall include promptly  forwarding to Buyer all payments  received by
the Seller that are made in respect of Buyer's receivables.

4.9 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
effect the transactions contemplated hereby. 4.10 Access to Records. Buyer shall
preserve all account ledgers,  computer software and data, books, records, files
and data  transferred  to Buyer  pursuant to this  Agreement  for a period of at
least six (6) years and shall at any reasonable time allow Seller or Shareholder
full access to such  records and shall,  at Seller's or  Shareholder's  expense,
furnish copies of any such material as may be requested.

                                    Article V
                                 Indemnification

5.1  Indemnification  by Seller and the  Shareholder.  In  addition to any other
remedies  available  to Buyer  and Key  under  this  Agreement,  or at law or in
equity,  each of  Seller  and the  Shareholder  shall,  jointly  and  severally,
indemnify,  defend and hold harmless each of Buyer and Key, and their respective
officers,  directors,  employees,  agents  and  stockholders,  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 attorneys' fees and expenses  (collectively,
the "Damages") that such indemnitees shall incur or suffer,  which arise, result
from or relate to (i) any breach of, or failure by Seller or the  Shareholder to
perform, their respective re presentations,  warranties, covenants or agreements
in this Agreement or in any schedule,  certificate,  exhibit or other instrument
furnished or delivered to Buyer and Key by Seller or the Shareholder  under this
Agreement and (ii) the Retained Liabilities.

5.2  Indemnification  by Buyer  and  Key.  In  addition  to any  other  remedies
available to Seller or the  Shareholder  under this  Agreement,  or at law or in
equity, Buyer and Key shall, jointly and severally,  indemnify,  defend and hold
harmless the  Shareholder,  Seller and its  officers,  directors,  employees and
agents  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 or 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 Seller or the Shareholder
by or on behalf of Buyer or Key under this Agreement.

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
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.

                                   Article VI

warranties,  covenants and  agreements  made by the parties hereto shall survive

Agreement  shall be deemed to have been  representations  and  warranties by the
respective party or parties,  as the case may be, and shall also survive without
limitation despite any investigation made by any party hereto or on its behalf.

instrument.

                                    ARTICLE I
                                PURCHASE AND SALE

1.1 Purchase and Sale of TST Shares. Subject to the terms and conditions of this
Agreement,  the Shareholders  agree to sell and convey to Key, free and clear of
all  Encumbrances  (as  defined in Section  2.1.8.1  hereof),  and Key agrees to

                               OF THE SHAREHOLDERS

2.1   Representations   and   Warranties  of  the   Shareholders.   The  express
representations  and warranties of the Shareholders  contained in this Article 2
are  exclusive  and are in lieu of all  other  representations  and  warranties,
express, implied or statutory, or otherwise.  Subject to the foregoing,  each of
the  Shareholders  jointly  and  severally  represents  and  warrants  to Key as
follows:

2.1.1  Organization and Standing.  TST is a corporation duly organized,  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.  Copies of TST's  Certificate  of  Incorporation,  Articles  of
Incorporation, Bylaws (all as amended to the date hereof), Articles of Merger of
K&L Neill Corp.  ("K&L") into TST, and a Certificate of Good Standing  issued by
the Comptroller of the State of Texas are attached hereto as Schedule 2.1.1. TST
does not now conduct (and has never conducted)  operations  outside of the State
of Texas.

2.1.2  Agreement  Authorized  and its Effect on Other  Obligations.  Each of the
Shareholders is a resident of the State of Texas, above the age of 18 years, and
each has the legal capacity and requisite power and authority to enter into, and
perform his or her 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  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 (i) the  Articles  of
Incorporation or Bylaws of TST or (ii) any obligation, indenture, mortgage, deed
of  trust,  lease,  contract  or other  agreement  to which TST or either of the
Shareholders  is a party or by which TST or either of the  Shareholders or their
respective properties are bound.

2.1.3  Capitalization  of TST. The authorized  capitalization of TST consists of
50,000 shares of TST Common Stock of which, as of the date hereof, 15,282 shares
are issued and  outstanding  (the "TST  Shares")  and held  beneficially  and of
record  by the  Shareholders.  On  the  date  hereof,  TST  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 TST  Common  Stock are  validly  issued,  fully  paid and
non-assessable and are not subject to preemptive rights. None of the outstanding
shares of TST Common Stock are subject to any voting trust,  voting agreement or
other agreement or understanding with respect to the voting thereof,  nor is any
proxy in existence with respect thereto.

2.1.4 Ownership of TST Shares. Except as disclosed on Schedule 2.1.4 hereto, the
Shareholders hold good and valid title to all of the TST Shares,  free and clear
of all Encumbrances.  The Shareholders possess full authority and legal right to
sell,  transfer  and  assign  to Key the  TST  Shares,  free  and  clear  of all
Encumbrances.  Upon transfer of the TST Shares to Key by the  Shareholders,  Key
will own the TST Shares free and clear of all Encumbrances.  There are no claims
pending or, to the knowledge of either of the Shareholders,  threatened, against
TST or either of the  Shareholders  that  concern or affect the title to the TST
Shares or that seek to compel the issuance of capital stock or other  securities
of TST.

2.1.5 No Subsidiaries. Except as disclosed on Schedule 2.1.5 hereto, there is no
corporation, partnership, joint venture, business trust or other legal entity in
which TST,  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 TST's audited
balance  sheet (the "12/31  Balance  Sheet ") and related  statements of income,
retained earnings and cash flows, with appended notes which are an integral part
of such statements (collectively,  the "12/31 Financial Statements"),  as of and
for the 12 months ended December 31, 1996 (the "Balance Sheet Date").  The 12/31
Financial  Statements are attached hereto as Schedule 2.1.6. The 12/31 Financial
Statements are true,  correct and complete in all material  respects and present
fairly the financial condition of TST as of the dates indicated, and the results
of operations for the respective  periods  indicated,  and have been prepared in
accordance with generally accepted  accounting  principles as promulgated by the
American  Institute  of  Certified  Public  Accountants  ("GAAP")  applied  on a
consistent basis, except as noted therein.  The accounts receivable reflected in
the 12/31 Balance  Sheet,  or which have been  thereafter  acquired by TST, have
been collected or are current and collectible in the aggregate  recorded amounts
thereof.  The  inventories of TST reflected in the 12/31 Balance Sheet, or which
have been thereafter  acquired by TST,  consist of items of quality and quantity
usable and  salable in the normal  course of TST's  business,  and the values at
which such inventories are carried are the lower of cost or market.

2.1.7  Liabilities.  Except as disclosed on Schedule  2.1.7  hereto,  TST has no
liabilities or  obligations,  either  accrued,  absolute or  contingent,  nor do
either of the  Shareholders  have any knowledge of any potential  liabilities or
obligations, which would materially or adversely affect the value and conduct of
the business of TST,  other than those (i) reflected or reserved  against in the
12/31 Balance Sheet or (ii)  incurred in the ordinary  course of business  since

for each  period for which any such  returns,  reports,  or  estimates  were due

have  been paid  other  than  those  being  contested  in good  faith by TST,  a
description  of  which  is  included  in  Schedule  2.1.11  hereto;  and the tax

GAAP, to cover  liabilities of TST at the date thereof for all taxes,  including

never been examined by the Internal Revenue Service or the taxing authorities of
any other  jurisdiction for the time period commencing January 1, 1993 up to and
including  the  date  of  this  Agreement  and  to  the  best  knowledge  of the
Shareholders,  for any period prior to January 1, 1993, and there are no current
or pending audits by the Internal Revenue Service. There are no tax liens on any
assets of TST  except for taxes not  currently  due.  TST is not now,  never has
been, and has never  attempted to become,  a Subchapter S Corporation  under the
Internal Revenue Code of 1986, as amended.

2.1.12 Intellectual  Property.  TST owns or possess licenses to use all patents,
patent applications,  trademarks and service marks (including  registrations and
applications  therefor),  trade names,  copyrights and written  know-how,  trade
secrets  and all other  similar  proprietary  data and the  goodwill  associated
therewith  (collectively,  "Intellectual  Property") that are either material to
its business or that are necessary for the rendering of any services rendered by
it and  the  use or  sale  of any  equipment  or  products  used  or  sold by it
(collectively, the "TST Intellectual Property"), including all such Intellectual
Property  listed in Schedule  2.1.12 hereto.  The TST  Intellectual  Property is
owned or licensed by TST free and clear of any Encumbrance.  TST has not granted
to any other person any license to use any of the TST Intellectual Property. TST
has not received any notice of infringement, misappropriation, or conflict with,
the  intellectual  property rights of others in connection with the use by it of
the TST  Intellectual  Property or otherwise in connection with the operation of
its business.

2.1.13  Title  to and  Condition  of  Assets.  TST has  good,  indefeasible  and
marketable title to all its properties, interests in properties and assets, real
and personal,  reflected in the 12/31 Balance Sheet or in Schedule 2.1.8 hereto,
free and clear of any  Encumbrance,  except (i)  Encumbrances  reflected  in the
12/31  Balance Sheet or in Schedule  2.1.8 hereto,  (ii) liens for current taxes
not yet due and payable,  and (iii) such  imperfections of title,  easements and
Encumbrances, if any, as are not substantial in character, amount, or extent and
do not and will not  materially  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 TST. All leases pursuant to which
TST 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 TST and in
respect  to which TST has not taken  adequate  steps to  prevent a default  from
occurring.  The  buildings and premises of TST that are used in its business are
in good operating condition and repair,  subject only to ordinary wear and tear.
All hot  oilers,  vacuum  trucks,  pump  trucks,  transport  trucks,  machinery,
transportation equipment,  vehicles, tools and other major items of equipment of
TST 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.  All such  assets  conform in all  material  respects to all
applicable  laws  governing  their use. No notice of any  violation  of any law,
statute,  ordinance,  or regulation relating to any such assets has been (or are
being)  received  by TST or any of the  Shareholders,  except  such as have been
fully complied with.

2.1.14 Contracts.  All contracts,  leases,  plans or other arrangements to which
TST is a party,  by which it is bound or to which  TST or the  assets of TST are
subject  are in  full  force  and  effect,  and  constitute  valid  and  binding
obligations  of TST and  the  other  parties  thereto.  TST 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 material  default  thereunder.  No contract has
been  entered  into on  terms  which  could  reasonably  be  expected  to have a
materially  adverse effect on TST.  Neither of the Shareholders has received any
information  which would cause such Shareholder to conclude that any customer of
TST will (or is likely  to) cease  doing  business  with TST (or any  successors
thereto)  as a  result  of the  consummation  of the  transactions  contemplated
hereby.  The Shareholders have provided Key with copies of all of TST's material
contracts which are to be performed in whole or in part after the date hereof.

2.1.15  Licenses and Permits.  Except as set forth on Schedule 2.1.15 hereto and
on  Schedule   2.1.17  hereto,   TST  possesses  all  permits,   authorizations,
certificates,   approvals,   registrations,   variances,   waivers,  exemptions,
rights-of-way,  franchises,  ordinances, licenses and other rights of every kind
and character (collectively, the "Permits") necessary under law or otherwise for
it to conduct its business as now being conducted and to own, operate,  maintain
and use its  assets  in the  manner  in  which  they  are  now  being  operated,
maintained and used (collectively,  the "TST Permits").  Each of the TST Permits
and the  rights  of TST with  respect  thereto  is (and  will be  following  the
consummation of the transactions  contemplated hereby) valid and subsisting,  in
full force and effect,  and enforceable by TST subject to administrative  powers
of regulatory agencies having jurisdiction. TST is in compliance in all material
respects with the terms of each of the TST Permits. None of the TST Permits have
been, or to the knowledge of either of the  Shareholders,  are threatened to be,
revoked, canceled, suspended or modified. Copies of the TST Permits are attached
hereto as Schedule 2.1.15.

2.1.16  Litigation.  Except as set forth on Schedule 2.1.16 hereto,  there is no
suit,  action, or legal or administrative,  arbitration,  or other proceeding or
governmental  investigation pending to which TST is a party or, to the knowledge
of  either  of the  Shareholders,  might  become a party  or which  particularly
affects  TST,  nor is any change in the zoning or building  ordinances  directly
affecting  the real property or leasehold  interests of TST,  pending or, to the
knowledge of either of the Shareholders, threatened.

2.1.17 Environmental Compliance.

2.1.17.1  Environmental  Conditions.  Except  as set  forth on  Schedule  2.1.17
hereto,  there are no  environmental  conditions  or  circumstances,  including,
without limitation,  the presence or release of any hazardous substance,  on any
property  presently or previously  owned or leased by TST, or on any property to
which hazardous substances or waste generated by the operations of TST or by the
use of the assets of TST were  disposed  of,  which  would  result in a material
adverse change in the business or business prospects of TST. The term "hazardous
substance" means (i) asbestos,  polychlorinated  biphenyls,  urea  formaldehyde,
lead based  paint,  radon gas,  petroleum,  oil,  solid  waste,  pollutants  and
contaminants,  and (ii) any chemicals,  materials, wastes or substances that are

material  to its  business  or  operations,  and  is  operating  in  substantial
compliance thereunder;

2.1.17.3 Compliance.  Except as set forth on Schedule 2.1.17 hereto, neither the

order or notice  requirement  pertaining  to (a) the  condition or protection of
air,  groundwater,  surface water, soil, or other  environmental  media, (b) the
environment,  including  natural  resources  or any activity  which  affects the
environment,  or (c) the regulation of any pollutants,  contaminants,  waste, or
substances (whether or not hazardous or toxic),  including,  without limitation,
the Comprehensive Environmental Response Compensation and Liability Act (42 U.S.
C. ss.9601 et seq.) ("CERCLA") , the Hazardous Materials  Transportation Act (49

have  been  amended  or  supplemented  from  time  to  time   (collectively  the
"Applicable  Environmental  Laws"),  other than violations that in the aggregate
are not material to the business or operations of TST;

2.1.17.4 Past Compliance.  None of the operations or assets of TST has ever been
conducted  or  used  in  such a  manner  as to  constitute  a  violation  of any
Applicable  Environmental  Laws, other than violations that in the aggregate are
not material to the business or operations of TST;

2.1.17.5 Environmental Claims. No notice has been served on TST or either of the
Shareholders from any entity,  governmental  agency or individual  regarding any
existing,  pending or threatened investigation,  inquiry,  enforcement action or
litigation  related to alleged  violations  under any  Applicable  Environmental
Laws,  or  regarding  any claims for  remedial  obligations,  response  costs or
contribution under the Applicable Environmental Laws;

2.1.17.6  Renewals.  Neither of the Shareholders  knows of any reason TST or its
successors  would not be able to renew any of the  permits,  licenses,  or other
authorizations required pursuant to any Applicable Environmental Laws to operate
and use any of assets of TST for their current purposes and uses; and

2.1.17.7  Asbestos  and  PCBS.  No  known  material  amounts,  except  as may be
described on Schedule 2.1.17 hereto, of friable asbestos  currently exist on any
property owned or operated by TST, nor do known polychlorinated  biphenyls exist
in concentrations of 50 parts per million or more in electrical  equipment owned
or being used by TST in the operations or on the properties of TST.

2.1.18 Compliance with Other Laws. TST is not in violation of or in default with
respect to, or in alleged  violation of or alleged  default with respect to, the
Occupational Safety and Health Act (29 U.S.C. ss.651 et seq.) as amended, or any
other applicable law (including zoning laws) or any applicable rule, regulation,
or any writ or  decree  of any  court  or any  governmental  commission,  board,

required to be filed with any governmental commission,  board, bureau, agency or
instrumentality, other than violations that in the aggregate are not material to
the business or operations of TST.

2.1.19 ERISA Plans,  Labor Issues.  Other than TST's  employee  health plan (the
"TST  Health  Plan") and profit  sharing  plan (the "TST Profit  Sharing  Plan")
contained  or  described  in Schedule  2.1.8.8  hereto,  TST does not  currently
sponsor,  maintain  or  contribute  to,  and  has  not  at any  time  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  ("ERISA").  As to the TST Health Plan,  the TST Profit Sharing Plan and
all other TST Employee Benefit Arrangements:

(i) the TST Health Plan,  the TST Profit Sharing Plan and all other TST Employee
Benefit  Arrangements  comply  with and have  been  administered  in form and in
operation in compliance with all applicable laws including,  without limitation,
ERISA,  the  Internal  Revenue Code of 1986,  as amended  (the  "Code),  and the
Consolidated  Omnibus  Reconciliation  Act of 1985,  as amended  ("COBRA"),  and
neither  of the  Shareholders  has  received  any notice  from any  governmental
authority questioning or challenging such compliance;  (ii) TST's administration
and  operation  of the TST Health Plan and the TST Profit  Sharing  Plan has not
been  conducted  in such a manner  as would  give  rise to any  material  fines,
penalties,  taxes, claims or charges against TST by a governmental entity or any
third party or otherwise, result in a material adverse effect on TST's financial
condition;

(iii)  funding of the TST Profit  Sharing Plan is in the sole  discretion of TST
regardless  of past funding  practices,  and the TST Profit  Sharing Plan may be
terminated  at any time without  liability to TST other than the  obligation  to
distribute the funds held by the TST Profit Sharing Plan in accordance  with the
provisions thereof;

(iv) there has been no event or  condition  which  presents  a material  risk of
termination of the TST Profit Sharing Plan or the TST Health Plan; and

(v) the  execution,  delivery and  performance  of this Agreement will not cause
either the TST Health Plan or the TST Profit  Sharing Plan to be  terminated  or
otherwise  adversely  affect the  administration  or  operation  thereof.  TST's
administration  of the TST Health Plan and the TST Profit Sharing Plan following
the Closing in the same manner as such plans were  administered  by TST prior to
the Closing  will not violate any  applicable  laws or  otherwise  result in the
material  adverse effect on the financial  condition of TST. TST has not engaged

to any customer, supplier,  government employee or other person who is or may be
in a  position  to help or  hinder  the  business  of TST (or to  assist  TST in
connection with any actual or proposed  transaction) which (i) might subject TST
to any damage or penalty in any civil,  criminal or  governmental  litigation or
proceeding,  (ii) if not given in the past, might have had a materially  adverse
effect on the assets,  business or  operations of TST, or (iii) if not continued

similar payment.

                      REPRESENTATIONS AND WARRANTIES OF KEY


3.1  Representations  and  Warranties  of Key. The express  representations  and
warranties  of Key  contained in this Article 3 are exclusive and are in lieu of
all other  representations  and warranties,  express,  implied or statutory,  or
otherwise.  Subject to the foregoing, Key represents and warrants to each of the
Shareholders as follows:

3.1.1  Organization and Standing.  Key is a corporation duly organized,  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.

3.1.2 Agreement Authorized and its Effect on Other Obligations. The consummation
of the transactions contemplated hereby have been duly and validly authorized by
all necessary corporate action on the part of Key, and this Agreement is a valid
and  binding  obligation  of  Key  enforceable   (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
performance  of this  Agreement  by Key will not  conflict  with or  result in a
violation or breach of any term or provision  of, or  constitute a default under
(i) the  Articles of  Incorporation  or Bylaws of Key,  or (ii) any  obligation,
indenture,  mortgage, deed of trust, lease, contract or other agreement to which
Key or any of its property is bound.

3.1.3  Consents  and  Approvals.  No  consent,   notice,   approval,   order  or
authorization of, or declaration, filing, or registration with, any governmental
or regulatory authority,  or any other person is required to be obtained or made
by Key in  connection  with  its  execution,  delivery  or  performance  of this
agreement or the consummation by it of the transactions contemplated hereby.

3.1.4 Key's  Access to TST's  Assets and Records.  Key  acknowledges  that it is
actively  engaged in the same  business as is TST,  that it has been afforded an
opportunity to examine the assets and records of TST, discuss TST's business and
operations with the Shareholders, and investigate the condition of the assets of
TST,  and  that  Key is  entering  into  this  Agreement  on the  basis  of such
investigation and the representations and warranties of the Shareholders.

3.1.5 TST's Stock Not Registered.  TST is a privately held corporation,  and Key
acknowledges  such. TST's stock has not been registered under the Securities Act
of 1933, as amended (the "Act"),  or under any applicable state securities laws,
and the stock, therefore, cannot be offered for sale, sold, transferred, pledged
or  otherwise   hypothecated   except  in  accordance   with  the   registration
requirements  of the Act and such  other  state laws as may be  applicable.  Key
acknowledges  that TST has made available to it such  information and documents,
and that Key  understands  the risk  associated with ownership of TST and Key is
capable of bearing the financial risk associated  therewith.  The TST Shares and
the dealings with Key are proceeding in reliance on exemptions from registration
or qualification requirements pursuant to state law.

all  fees and  expenses,  including  fees and  expenses  of  counsel,  financial
advisors,  and  accountants  incurred in connection  with this Agreement and the
transactions  contemplated  hereby shall be paid by the party incurring such fee

cause the TST  Employees to remain in the  employment of TST through the Closing
Date.  Key will  cause TST to  continue  the  employment  of the TST  Employees;

obligation of TST to continue any such employee as an employee of TST.

in effect may, at the option of Key, be continued,  amended or  terminated.  Key

under the terms of all such TST Employee Benefit  Arrangements  that have vested
or accrued at or prior to the Closing Date or that become vested or accrued as a
result of the transactions contemplated hereby.

7.5  Noncompetition.  Each of the Shareholders  agrees that for a period of five
(5)  years  from the  Closing  Date,  such  Shareholder  will not,  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 3% of any  security of any class of any  corporation  or other  business
entity (i) engage in  competition  with the business or businesses  conducted by
TST,  Key or any  affiliate  of Key as of the  Closing  Date,  or in any service
business  the  services of which are  provided  and  marketed by TST, Key or any
affiliate of Key as of the Closing Date in Texas or New Mexico; (ii) request any
present  customers or suppliers of TST to curtail or cancel their  business with
TST,  Key or any  affiliate  of  Key;  (iii)  disclose  to any  person,  firm or
corporation  any trade,  technical or  technological  secrets of TST, Key or any
affiliate  of Key or any details of their  organization  or business  affairs or
(iv) induce or actively  attempt to  influence  any  employee of TST, Key or any
affiliate of Key to terminate his employment.  Each of the  Shareholders  agrees
that if either the length of time or geographical area set forth in this Section
7.5 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  7.5  are in  addition  to  any  other
obligations  that the Shareholders may have under the laws of the State of Texas
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 Shareholders further agrees and acknowledges that TST, Key
and its  affiliates  do not have any  adequate  remedy at law for the  breach or
threatened breach by such Shareholder of this covenant,  and agree that TST, 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 Shareholder from
such breach or threatened breach. If any provisions of this Section 7.5 are held
to be invalid or against  public  policy the remaining  provisions  shall not be
affected thereby.  Each of the Shareholders  acknowledges that the covenants set
forth in this Section 7.5 are being  executed and delivered by such  Shareholder
in  consideration  of the covenants of Key contained in this Agreement,  and for
other good and valuable consideration, receipt of which is hereby acknowledged.

7.6 Material  Adverse  Change.  As used in this  Agreement,  the term  "material
adverse   change"   means  any  change,   event,   circumstance   or   condition
(collectively,  a "Change")  which when  considered with all other Changes would
reasonably  be  expected  to  result  in  a  "loss"  having  the  effect  of  so
fundamentally  adversely affecting the business or financial prospects of Key or
TST, as the case may be, that the benefits reasonably expected to be obtained by
Key or  TST,  as the  case  may  be,  as a  result  of the  consummation  of the
transactions  contemplated by this Agreement would be jeopardized  with relative
certainty.  The term "loss" shall mean any and all direct or indirect  payments,
obligations, assessments, losses, loss of income, liabilities, fines, penalties,
costs  and  expenses  paid or  incurred  or more  likely  than not to be paid or
incurred,  or  diminutions  in value of any kind or character  (whether known or
unknown,  conditional  or  unconditional,  choate  or  inchoate,  liquidated  or
unliquidated,  secured or unsecured, accrued, absolute, contingent or otherwise)
that are more likely than not to occur,  including without limitation penalties,
interest on any amount payable to a third party as a result of the foregoing and
any legal or other  expenses  reasonably  incurred or more likely than not to be
incurred in connection  with  investigating  or defending  any demands,  claims,
actions or causes of action that, if adversely  determined,  would likely result
in losses,  and all amounts paid in settlement  of claims or actions;  provided,
that losses  shall be net of any  recoveries  by TST from third  parties and any
insurance  proceeds TST is entitled to receive from a  non-affiliated  insurance
company on account of such losses (after taking into account any costs  incurred
in obtaining such proceeds and any increase in insurance premiums as a result of
a claim with respect to such proceeds).

7.7 Shareholder Employment.  After the Closing Date, Keith Neill shall remain in
the employment of TST at a monthly salary of $8,000.

                                    ARTICLE 8
                                 INDEMNIFICATION

8.1  Indemnification  by the  Shareholders.  In addition  to any other  remedies
available  to Key under  this  Agreement,  or at law or in  equity,  each of the
Shareholders  shall  jointly and severally  indemnify,  defend and hold harmless
Key, and its officers,  directors,  employees, agents and stockholders,  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  attorneys'  fees and  expenses
(collectively,  the  "Damages") in excess of  $150,000.00  in the aggregate that
such indemnitees  shall incur or suffer,  which arise,  result from or relate to
any breach of, or failure  by, 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 Key
by the  Shareholders  under  this  Agreement;  provided,  however,  that (i) the
Shareholders'  aggregate  obligations  to  indemnify  Key and the other  parties
identified above shall never exceed the aggregate sum of $8,500,000.00; (ii) the
Shareholders shall not be required to so indemnify, defend and hold harmless Key
and its officers,  directors,  employees,  agents and stockholders,  against and
with  respect to any  Damages  incurred as a result of a breach by either of the
Shareholders  of  their  respective   representations  and  warranties  in  this
Agreement or in any schedule, certificate, exhibit or other instrument furnished
or delivered to Key by any of the  Shareholders  under this  Agreement for which
Key  fails  to  provide  written  notice  of a claim  for  such  Damages  to the
Shareholders on or before the expiration of the survival period (as specified in
Section 9.2 hereof) of the specific  representation  or warranty alleged to have
been breached;  (iii) in the event that Key can recover  Damages for which it is
indemnified by the  Shareholders  pursuant to this Section 8.1 from a collateral
source including,  but not limited to, a third party or insurance coverage,  and
does in fact  collect  all or a portion  of such  Damages  from such  collateral
source,  then Key agrees not to enforce its right to indemnification  under this
Section 8.1 to the extent of such third party  collections;  and (iv) Key agrees
that  it  will  not  seek  indemnification   under  this  Section  8.1  for  any
environmental  remedial work on TST's properties unless TST (or Key) is required
to perform such work by a third party or by a governmental entity or agency.

8.2  Indemnification  by Key. In addition to any other remedies available to the
Shareholders under this Agreement,  or at law or in equity, Key shall indemnify,
defend and hold  harmless each of the  Shareholders  against and with respect to
any and all  Damages  in  excess  of  $150,000.00  in the  aggregate  that  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 the Shareholders by or on
behalf of Key under this Agreement;  provided, however, that (i) Key's aggregate
obligation  to  indemnify  the  Shareholders  shall  never  exceed  the  sum  of
$8,500,000.00;  (ii) Key shall not be required to so indemnify,  defend and hold
harmless  the  Shareholders  and their  employees  and agents  against  and with
respect  to any  Damages  incurred  as a result of a breach by Key of any of its
representations   and   warranties  in  this   Agreement  or  in  any  schedule,
certificate,   exhibit  or  other  instrument  furnished  or  delivered  to  the
Shareholders  by Key under this  Agreement  for which the  Shareholders  fail to
provide  written  notice of a claim  for such  Damages  to Key on or before  the
expiration of the survival period (as is specified in Section 9.2 hereof) of the
specific representations or warranty alleged to have been breached; and (iii) in
the event that the  Shareholders can recover Damages for which it is indemnified
by Key pursuant to this Section 8.1 from a collateral source including,  but not
limited to, a third party or insurance coverage, and does in fact collect all or
a portion of such Damages from such  collateral  source,  then the  Shareholders
agree not to enforce its right to indemnification  under this Section 8.2 to the
extent of such third party collections.

8.3  Indemnification  Procedures.  If any party  hereto  discovers  or otherwise
becomes  aware of a claim  for  Damages  arising  under  this  Article  8,  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 Damages  arising  under
Sections 8.1 or 8.2 hereof may be made, 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.  Any 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,  and  the
expenses  of  such  defense  shall  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.

8.4 Litigation  Indemnification.  The parties hereto  acknowledge  that TST is a
defendant in Cause No. H-96-0163 pending in the United States District Court for
the  Southern  District  of  Texas,  Houston  Division,  entitled  AMERADA  HESS
CORPORATION  VS.  T.S.T.  PARAFFIN  SERVICE  COMPANY,  INC.  (the  "Amerada Hess
Litigation").  The parties hereto further  acknowledge that there are collateral
matters  which are being  litigated  insofar  as the  validity  of an  indemnity
agreement  executed as a result of  settlement  by TST in Cause No.  C-2244-94-D
pending in the 206th Judicial  District Court of Hidalgo  County,  Texas,  which
involved  Regina  Valenzuela  as Next  Friend of Brenda  Janette  Montanez.  The
parties  hereto  further  acknowledge  that TST has remaining upon its insurance
coverage the sum of $250,000 which can be applied toward any damages  awarded in
the Amerada Hess  Litigation  or which may be used to help fund a settlement  of
this  litigation.  In addition to any other  remedies  available  to the parties
hereto under this Agreement,  or at law or in equity,  the parties hereto hereby
agree that in the event that  damages  and/or  settlement  of the  Amerada  Hess
Litigation  results in an amount in excess of the $250,000  insurance  coverage,
that such excess will be paid as follows:

(i) The  Shareholders  shall  commence  paying  with the first  dollar  over the
$250,000  and shall  continue  paying all  dollars  thereafter  until such award
and/or settlement amount reaches $1,250,000; and

(ii) For all  amounts  awarded or for which  settlement  may be had in excess of
$1,250,000  and  commencing  with  the  first  dollar  after   $1,250,000,   the
Shareholders shall pay 20% of each dollar and TST shall pay 80% of each dollar.

The Shareholders and Key agree that they will jointly, at TST's expense,  pursue
any third party, including  Petrosurance Company, for reimbursement,  collateral
source money, or to enforce any other indemnity agreements. For monies recovered
as a result of such pursuit,  the  Shareholders and TST shall divide each dollar
recovered  according to a ratio formula determined by a fraction whose numerator
shall  consist of the total amount of money paid by either the  Shareholders  or
TST,  and the  denominator  shall  consist of the total  monies paid by both the
Shareholders and TST. Such fraction shall then be multiplied times the recovered
amount of money to determine those sums reimbursable  either to the Shareholders
or TST. Key further agrees that upon the Closing, it shall cause TST to directly
participate  in the Amerada Hess  Litigation  and proceed with due  diligence to
reach  resolution  thereof by employing  its own counsel to commence  such legal
activities as may be necessary to (i) apply pressure to TST's insurance carrier,
AIG, to settle the  Amerada  Hess  Litigation,  and/or to tender the full policy
amounts  to  assist in  funding  the  settlement  of said  litigation,  and (ii)
initiate such activities as may be necessary to commence  meaningful  settlement
discussions  with  Amerada  Hess and other  matters  which  management  may deem
prudent to rapidly  conclude the Amerada Hess  Litigation.  The first $25,000 of
the costs and expenses of such counsel  shall be borne by TST with the remaining
costs and expenses being shared equally by TST and the  Shareholders.  Key shall
not consent to settle the Amerada Hess  Litigation  for an amount above $250,000
without  the  prior  consent  of  the  Shareholders,  such  consent  not  to  be
unreasonably withheld.

                                    ARTICLE 9
                                  MISCELLANEOUS

shall  consult  with each other  before  issuing any press  release or otherwise
making any public  statement with respect to this Agreement or the  transactions
contemplated hereby, and shall not issue any such press release or make any such
public statement prior to receiving approval from the other party, such approval
not to be unreasonably withheld or delayed. No announcement shall be made by any
of the  parties  hereto  prior to the  Closing  except  as may  specifically  be
required  under the terms of this  Agreement,  except when in the opinion of the
parties' counsel such public statement or announcement is legally required.

9.2 Survival of Representations,  Warranties and Covenants.  All representations
and  warranties  made by the  parties  hereto  shall  survive for a period of 12

behalf of any of the parties hereto; provided, however, that the representations
and  warranties  contained  in Section  2.1.11  hereof shall  survive  until the
expiration of the applicable statute of limitations associated with the taxes at
issue. All statements contained in any certificate,  schedule,  exhibit or other
instrument  delivered  pursuant to this  Agreement  shall be deemed to have been
representations  and warranties by the respective party or parties,  as the case
may be, and shall also  survive for a period of 12 months from the Closing  Date
despite  any  investigation  made by any  party  hereto  or on its  behalf.  All
covenants and agreements contained herein shall survive as provided herein.

9.3 Entirety.  This Agreemennt  embodies the entire  agreement among the parties
with respect to the subject matter hereof,  and all prior agreements between the
parties with respect thereto are hereby superseded in their entirety.

shall be in  writing  and  shall be  delivered  by  courier,  sent by  facsimile
transmission  or first class  registered  or certified  mail,  postage  prepaid,

validly  existing  and  in  good  standing  under  the  laws  of  its  state  of
organization,  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

material adverse effect on the business of Seller.

1. Agreements  Authorized and their Effect on Other  Obligations.  The execution
and delivery of this Agreement have been  authorized by all necessary  corporate
and  shareholder  action on the part of the Seller,  and this  Agreement  is the
valid  and  binding  obligation  of the  Seller  and  each  of the  Shareholders
enforceable  (subject  to  normal  equitable  principals)  against  each of such
parties 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 performance of
this Agreement and the  consummation of the  transactions  contemplated  hereby,
will not  conflict  with or  result  in a  violation  or  breach  of any term or
provision of, nor constitute a default under (i) the charter or bylaws (or other
organizational  documents)  of  the  Seller,  (ii)  any  obligation,  indenture,
mortgage,  deed of trust, lease, contract or other agreement to which the Seller
or the  Shareholders  is a party or by which the Seller or the  Shareholders  or

marketable  title  to all of the  Assets,  free and  clear  of any  Encumbrances
(defined  below).  All of the Assets are in a state of good operating  condition
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.  All of the Assets conform to all applicable  laws governing
their  use.  Except  as set forth on  Schedule  2.1.3  hereto,  no notice of any
violation of any law, statute,  ordinance,  or regulation relating to any of the

security interests,  pledges, mortgages, deeds of trust, claims, rights of first
refusal, options, charges, restrictions or conditions to transfer or assignment,
liabilities,  obligations,  privileges,  equities,  easements,  rights  of  way,

governmental  authority  or from any  other  third  party  in  order to  validly
transfer the Assets hereunder.

1. No ERISA  Plans or Labor  Issues.  No  employee  benefit  plan of the Seller,
whether or not  subject to any  provisions  of the  Employee  Retirement  Income
Security Act of 1974, as amended,  will by its terms or applicable  law,  become
binding upon or an obligation of Buyer. The Seller has not engaged in any unfair
labor  practices  which  could  reasonably  be  expected to result in a material
adverse effect on the Assets.  Except as set forth in Schedule 2.1.6 hereto, the
Seller has no dispute with any of its existing or former employees and there are
no labor disputes or, to the knowledge of the Seller or any of the Shareholders,
any disputes  threatened by current or former  employees of the Seller.  Neither
the Seller nor any of the  Shareholders  know of any claims or efforts by any of
its  employees  or by others to organize  their  employees  into a union  and/or
unions.

1.  Investigations;  Litigation.  No investigation or review by any governmental
entity with  respect to the Seller or any of the  transactions  contemplated  by
this  Agreement  is  pending  or, to the  knowledge  of the Seller or any of the

Seller or any of the  Shareholders  an intention to conduct the same.  Except as
set  forth  in  Schedule  2.1.7  hereto,  there is no suit,  action,  or  legal,
administrative,  arbitration,  or other proceeding or governmental investigation
pending  to which the  Seller or any of the  Shareholders  is a party or, to the
knowledge  of the  Seller or any of the  Shareholders,  might  become a party or
which  particularly   affects  the  Assets.   Neither  Seller  nor  any  of  the
Shareholders  know of any claims that any of its  officers,  employees or agents
have  violated  any state or federal  civil  rights law  including  the Michigan
Elliott-Larsen Civil Rights Act.

employee or agent of the  Seller,  or any other  person  acting on behalf of the
Seller,  have,  directly or  indirectly,  within the past five  years,  given or
agreed to give any gift or similar benefit to any customer, supplier, government
employee  or other  person who is or may be in a position  to help or hinder the
profitable conduct of the Businesses or the profitable use of the Assets, (or to
assist the 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  conduct of the Businesses or the profitable use of the Assets, or if
not continued in the future,  might  materially  adversely affect the profitable
conduct of the Businesses or the profitable use of the Assets.

1. Solvency.  The Seller is not now  insolvent,  nor will the Seller be rendered
insolvent by the occurrence of the transactions  contemplated by this Agreement.

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.

1. Untrue Statements.  The Seller has made available to Buyer true, complete and
correct  copies  of all  contracts,  documents  concerning  all  litigation  and
administrative  proceedings,  licenses,  permits,  insurance policies,  lists of
suppliers and customers,  and records relating principally to the Businesses and
the Assets, and such information covers all commitments and liabilities of Buyer
relating  principally to the Businesses and the Assets.  This Agreement does 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.

approved in writing by Buyer, the Seller and each of the Shareholders agree that
for a period  of 60 months  following  the date  hereof,  such  party  will not,

or  threatened  breach.  If any  provisions  of this  Section 5.1 are held to be
invalid or against public policy, the remaining provisions shall not be affected
thereby. The Seller and each of the Shareholders  acknowledge that the covenants
set forth in this Section 5.1 are being  executed and delivered by such party in

no liability or obligation with respect to any employee benefits of any Employee
except those benefits that accrue  pursuant to such  Employees'  employment with

utility  charges  incurred by the Assets  and/or  Businesses  purchased by Buyer
after the date hereof.

prorata  share of all such  taxes  for 1997,  prorated  to the date  hereof,  in
accordance with the standards of practice in Kalkaska County,  Michigan.  If the
actual  taxes  for the  current  year are not known as of the date  hereof,  the
apportionment  of  taxes  shall be upon the  basis  of taxes  for the  immediate
preceding  year,  provided  that,  if taxes for the current year are  thereafter
determined  to be more or less for the taxes for the  preceding  year (after any

the case may be, shall pay to the other any amount  required as a result of such
adjustment and as a covenant shall survive the Closing.

effect the transactions contemplated hereby.


                               I. Indemnification

Indemnification  Indemnification by the Seller and the Shareholders. In addition
to any other remedies  available to Buyer under this Agreement,  or at law or in
equity,  the Seller and each of the Shareholders  shall,  jointly and severally,
indemnify,  defend  and  hold  harmless  Buyer  and  its  officers,   directors,
employees,  agents and  stockholders,  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 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 the Seller,  any of the Affiliated  Companies or 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 the Seller or
each  of  the  Shareholders   under  this  Agreement;   and  (ii)  the  Retained
Liabilities.

A.  Indemnification  by Buyer.  In addition to any other  remedies  available to
Seller  under this  Agreement,  or at law or in equity,  Buyer shall  indemnify,
defend  and  hold  harmless  each of the  Shareholders  and the  Seller  and its
officers,  directors,  employees and agents  against and with respect to any and
all Damages that such  indemnities  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
Seller by or on behalf of Buyer under this Agreement.

A. Indemnification Procedure. If any party hereto discovers or otherwise becomes
aware of an  indemnification  claim  arising  under  Section  6.1 or 6.2 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 6, 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.

                       of the Sellers and the Shareholder

Representations and Warrantiesof the Sellers and the Shareholder Representations
and  Warranties of the Seller and the  Shareholders.  The Seller and each of the
Shareholders jointly and severally represent and warrant to Buyer as follows:

1.  Organization  and Good  Standing.  Seller and each  Affiliated  Company is a
corporation duly organized, validly existing and in good standing under the laws
of its state of organization,  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  where the failure to so qualify
would not have a material adverse effect on the business of Seller.

1. Agreements  Authorized and their Effect on Other  Obligations.  The execution
and delivery of this Agreement have been  authorized by all necessary  corporate
and shareholder action on the part of the Seller and Affiliated  Companies,  and
this Agreement is the valid and binding obligation of the Seller and each of the
Shareholders  enforceable (subject to normal equitable  principals) against each
of such parties 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
performance  of  this  Agreement  and  the   consummation  of  the  transactions
contemplated  hereby,  will not conflict with or result in a violation or breach
of any term or provision  of, nor  constitute a default under (i) the charter or
bylaws  (or  other  organizational   documents)  of  the  Seller  or  Affiliated
Companies,  (ii) any  obligation,  indenture,  mortgage,  deed of trust,  lease,
contract or other  agreement  to which the Seller,  Affiliated  Companies or the
Shareholders  is a party or by which the  Seller,  Affiliated  Companies  or the
Shareholders or their respective properties are bound; or (iii) any provision of
any  law,  rule,  regulation,  order,  permits,  certificate,   writ,  judgment,
injunction,  decree,  determination,  award  or  other  decision  of any  court,
arbitrator,  or other  governmental  authority  to which the Seller,  Affiliated
Companies or the Shareholders or any of their respective properties are subject.
Schedule 2.1.2. hereto contains a complete list of all shareholders of Seller as
of the Closing Date.

1.  Contracts.  Schedule  1.1(d)  hereto  sets  forth  a  complete  list  of all
contracts,  including  leases under which the Seller is lessor or lessee,  which
relate to the Assets and are to be  performed in whole or in part after the date
hereof.  All of the Contracts are in full force and effect, and constitute valid
and binding  obligations of the Seller. The Seller is not, and no other party to
any of the Contracts 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 a material  adverse  effect on
the use of the  Assets by  Buyer.  Neither  the  Seller,  any of the  Affiliated
Companies nor any of the Shareholders  have received any information which would
cause any of such parties to conclude  that any customer of the Seller or any of
the Affiliated Companies will (or is likely to) cease doing business with Buyer,
as  successor  to  the  Businesses,  as a  result  of  the  consummation  of the
transactions contemplated hereby.

1. Title to and  Condition  of Assets.  The  Seller has good,  indefeasible  and
marketable  title  to all of the  Assets,  free and  clear  of any  Encumbrances
(defined  below).  All of the Assets are in a state of good operating  condition
and repair, ordinary wear and tear excepted, and are free from any known defects
except (i) 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,  or (ii) as otherwise set forth in the Appraisal by Superior
Appraisals dated July 23, 1996, or (iii) as set forth in Schedule 2.1.4 (a). All
of the Assets conform to all applicable  laws governing their use. Except as set
forth on  Schedule  2.1.4 (b)  hereto,  no notice of any  violation  of any law,
statute,  ordinance,  or  regulation  relating  to any of the  Assets  has  been
received  by  the  Seller,  any  of  the  Affiliated  Companies  or  any  of the
Shareholders,   except  such  as  have  been  fully   complied  with.  The  term
"Encumbrances" means all liens, security interests, pledges, mortgages, deeds of
trust,  claims,  rights of first  refusal,  options,  charges,  restrictions  or
conditions  to transfer or  assignment,  liabilities,  obligations,  privileges,
equities, easements, rights of way, limitations, reservations, restrictions, and
other encumbrances of any kind or nature.

2. Bulk Sales Act Not  Applicable.  Neither the Seller nor any of the Affiliated
Companies  are, or were,  in the business of selling  merchandise  from stock or
manufacturing what it sells.

1.  Licenses and Permits.  Schedule  1.1(e) hereto sets forth a complete list of
all Permits necessary under law or otherwise for the operation,  maintenance and
use of the Assets in the manner in which they are now being operated, maintained
and used.  Each of the Seller  Permits  and the  Seller's  rights  with  respect
thereto is valid and  subsisting,  in full force and effect,  and enforceable by
the Seller  subject  to  administrative  powers of  regulatory  agencies  having
jurisdiction.  The Seller is in  compliance  in all material  respects  with the
terms of each of the Seller Permits. None of the Seller Permits have been, or to
the  knowledge  of the Seller,  any of the  Affiliated  Companies  or any of the
Shareholders,  are threatened to be, revoked,  canceled,  suspended or modified.
Upon  consummation of the transactions  contemplated  hereby,  all of the Seller
Permits  shall be  assignable  to Buyer  and upon such  assignment,  each of the
Seller  Permits  and  Buyer's  rights  with  respect  thereto  will be valid and
subsisting  in full  force and  effect,  and  enforceable  by Buyer  subject  to
administrative powers of regulatory agencies having jurisdiction.

1.  Intellectual  Property.  Section  1.1(c)  sets forth a complete  list of all
Intellectual  Property material to or necessary for the continued conduct of the
Businesses.  The Seller Intellectual Property is owned or licensed by the Seller
free and clear of any Encumbrances. Neither the Seller nor any of the Affiliated
Companies  have  granted  to any other  person  any  license  to use any  Seller
Intellectual Property. Use of the Seller Intellectual Property will not, and the
conduct of the Businesses did not, infringe, misappropriate or conflict with the
Intellectual  Property  rights of  others.  Neither  the  Seller  nor any of the
Affiliated  Companies  nor any of the  Shareholders  have received any notice of
infringement,  misappropriation,  or  conflict  with the  intellectual  property
rights  of  others  in  connection  with  the  use by the  Seller  or any of the
Affiliated Companies of the Seller Intellectual Property.

1.  Financial  Statements.  The Seller has delivered to Buyer copies of Seller's
unaudited balance sheet, copies of which are attached hereto as Schedule 2.1.8 (
the "Balance  Sheet") and related  statements of income,  retained  earnings and
cash flows (collectively,  the "Financial  Statements") as at and for the period
ending November 30, 1996, (the "Balance Sheet Date").  The Financial  Statements
are true,  correct and complete in all material  respects and present fairly and
fully the financial condition of the Seller as at the dates indicated,  and have
been prepared in accordance  with generally  accepted  accounting  principles as
promulgated by the American Institute of Certified Public  Accountants  ("GAAP")
applied on a consistent  basis,  except as noted therein.  Each of the Financial
Statements  include all adjustments  which are necessary for a fair presentation
of the Seller's results for that period. The inventories of the Seller reflected
in the Balance Sheet, or which have thereafter been acquired by Seller,  consist
of  items  of a  quality  and  quantity  salable  in the  normal  course  of the
Businesses.  The values at which such  inventories are carried are in accordance
with GAAP  applied on a consistent  basis,  and are  consistent  with the normal
inventory level and practices of Seller with respect to the Businesses.

1.  Absence  of  Certain  Changes  and  Events.  Other  than as a result  of the
transactions  contemplated by this Agreement and except as set forth in Schedule
2.1.9 hereto, since the Balance Sheet Date, there has not been:

"SEC") on or before April 3, 1997  registering  the resale of certain  shares of
Key Common Stock  issuable upon  conversion of certain  outstanding  convertible
debentures of Key and (ii) use its best efforts to cause the Shelf  Registration
Statement  to be declared  effective  by the SEC on or before July 3, 1997.  Key

Statement; provided, that (i) each of the Shareholders shall have all duties and
obligations  of a "Holder"  under the  Registration  Rights  Agreement and (ii),

Registration  Statement,  the Shareholders shall have no right to participate in

exercising their rights under the Registration  Rights  Agreement.  In the event
that the Shelf  Registration  Statement is not declared  effective by the SEC by

of  Closing  shall be paid by Seller.  The Buyer  shall be  responsible  for the
utility  charges  incurred by the Assets  and/or  Businesses  purchased by Buyer
after the date hereof.

(1) The Seller shall pay a prorata share of the personal  property taxes for the
Assets  sold by the  Seller to Buyer for all years  prior to the  Closing  and a
prorata  share of all such  taxes  for 1997,  prorated  to the date  hereof,  in
accordance with the standards of practice in Kalkaska County,  Michigan.  If the
actual  taxes  for the  current  year are not known as of the date  hereof,  the
apportionment  of  taxes  shall be upon the  basis  of taxes  for the  immediate
preceding  year,  provided  that,  if taxes for the current year are  thereafter
determined  to be more or less for the taxes for the  preceding  year (after any
appeal  of the  assessed  valuation  thereof  is  concluded),  Seller  and Buyer
promptly  shall adjust the proration of such taxes and Seller  and/or Buyer,  as
the case may be, shall pay to the other any amount  required as a result of such
adjustment and as a covenant shall survive the Closing.

(1) The Seller shall pay all taxes,  whether federal,  state or local,  assessed
against the Assets or the  Businesses  for that period of time prior to the date
hereof, including any and all

  sales  taxes,  use  taxes,   unemployment
compensation taxes or taxes arising out of the fact that Seller hired employees.

A. Construction of Building. Subsequent to the Closing Date the Seller agrees to
construct a building  for the Buyer on the  property  described  on Schedule 5.9
according  to plans  that will  hereafter  be  agreed  upon by the Buyer and the
Seller.  The Seller  shall not be  required  to spend  more than  Three  Hundred
Thousand  Dollars  ($300,000.00)  for the  construction of this building.  After
closing the Buyer shall have thirty (30) days to cancel this  obligation  of the
Seller.  In that event,  the Seller shall  forthwith  refund Buyer Three Hundred
Thousand Dollars ($300,000.00). Unless otherwise agreed in writing by the Buyer,
this sum  shall be paid in the form of a  cashier's  check,  bank  check or wire
transfer of immediately available funds.

A.  Consultant  Fees. The Buyer agrees that it shall be responsible for and save
the Seller and Shareholders harmless from those consultant fee charges set forth
in Schedule 5.10 hereof.

A. 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
effect the transactions contemplated hereby.


                               I. Indemnification

Indemnification  Indemnification by the Seller and the Shareholders. In addition
to any other remedies  available to Buyer under this Agreement,  or at law or in
equity,  the Seller and each of the Shareholders  shall,  jointly and severally,
indemnify,  defend  and  hold  harmless  Buyer  and  its  officers,   directors,
employees,  agents and  stockholders,  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 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 the Seller,  any of the Affiliated  Companies or 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 the Seller,  the
Affiliated Companies or each of the Shareholders under this Agreement;  and (ii)
the Retained Liabilities. Notwithstanding these provisions, the Buyer shall have
no claim  against  the  Seller or the  Shareholders  for the first Ten  Thousand
Dollars worth of Damages  pursuant to this Section 8.1. In addition,  the Seller
and the  Shareholders'  total liability for Damages pursuant to this Section 8.1
shall  not  exceed  Eight  Million  Eight  Hundred   Thousand   Dollars  (herein
"Indemnification  Cap").  In  determining  if the  Indemnification  Cap has been
reached,   Seller  and   Shareholders   shall  be  entitled  to  aggregate   any
indemnification  paid by Seller or Shareholders  pursuant to (a) this Agreement,
(b) a separate Asset Purchase Agreement between Buyer and Kalkaska  Construction
Service,  Inc.  dated  March  31,  1997,  and  closed  simultaneously  with this
Agreement, and (c) a Stock Purchase Agreement between the Buyer and Shareholders
dated March 31, 1997, and closed simultaneously with this Agreement.

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

A. Indemnification Procedure. If any party hereto discovers or otherwise becomes
aware of an  indemnification  claim  arising  under  Section  6.1 or 6.2 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 6, 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.


                                I. Miscellaneous

A. Survival of Representations,  Warranties and Covenants.  All representations,
warranties,  covenants and  agreements  made by the parties hereto shall survive

certificate,  schedule,  exhibit or other instrument  delivered pursuant to this
Agreement  shall be deemed to have been  representations  and  warranties by the
respective party or parties,  as the case may be, and shall also survive without

Service,  Inc.  dated  March  31,  1997,  and  closed  simultaneously  with this
Agreement, and (c) a Stock Purchase Agreement between the Buyer and Shareholders
dated March 31, 1997, and closed simultaneously with this Agreement.

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

A. Indemnification Procedure. If any party hereto discovers or otherwise becomes
aware of an  indemnification  claim  arising  under  Section  6.1 or 6.2 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 6, 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.

claims, costs, damages, losses, expenses, obligations,  liabilities, recoveries,
suits,  causes of action and  deficiencies,  including  interest,  penalties and

breach   of,  or  failure  by  the   Sellers   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 the Sellers under this Agreement. Notwithstanding these provisions, the

determining  if the  Indemnification  Cap has  been  reached,  Sellers  shall be
entitled  to  aggregate  any   indemnification   paid  by  Sellers  or  Kalkaska
Construction  Service,  Inc.  pursuant  to this  Agreement  or  pursuant  to two
separate  Asset  Purchase  Agreements  between  Buyer and Kalkaska  Construction
Service,  Inc.  dated  March  31,  1997,  and  closed  simultaneously  with this

representations, warranties, covenants or agreements in this Agreement or in any
schedule,  certificate,  exhibit or other  instrument  furnished or delivered to
Sellers by or on behalf of Buyer under this Agreement.

8.3.  Indemnification  Procedure.  If any party  hereto  discovers  or otherwise
becomes  aware of an  indemnification  claim arising under Section 8.1 or 8.2 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 Section 8, 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.indemnifying  party,  which consent

AJanuary 31, Balance  Sheet@) as at January 31, 1997 (the ABalance Sheet Date@).
The Seller Financial Statements present fairly and fully the financial condition

not, and no other party to any Transferred  Contract 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
Transferred  Contract has been entered into on terms which could  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  information  which would
cause such party to conclude  that any customer of Seller will (or is likely to)
cease doing business with Buyer,  as successor the Business,  as a result of the
consummation of the transactions contemplated hereby.

2.1.5.  Title to and  Condition  of Assets.  Seller has good,  indefeasible  and

Buyer in AS IS condition and neither Seller nor  Shareholders  make any warranty
of any  kind,  express  or  implied.  To  the  knowledge  of  either  Seller  or
Shareholders,  all of the Assets conform to all applicable  laws governing their
use. No notice of any violation of any law,  statute,  ordinance,  or regulation
relating  to any of the  Assets  has been  received  by Seller or  Shareholders,
except such as have been fully complied with. The term AEncumbrances@  means all
liens, security interests, pledges, mortgages, deeds of trust, claims, rights of
first  refusal,  options,  charges,  restrictions  or  conditions to transfer or
assignment, liabilities, obligations, privileges, equities, easements, rights of
way, limitations, reservations, restrictions, and other encumbrances of any kind
or nature.

2.1.6. Licenses and Permits. Each of the Seller Permits and Seller=s rights with
respect  thereto  is  valid  and  subsisting,  in full  force  and  effect,  and
enforceable by Seller subject to  administrative  powers of regulatory  agencies
having  jurisdiction.  Seller is in compliance in all material respects with the
terms of each of the Seller Permits.  None of the Seller Permits has been, or to
the  knowledge  of  Seller  or  Shareholders,  are  threatened  to be,  revoked,
canceled,   suspended  or  modified.   Upon  consummation  of  the  transactions
contemplated hereby, each of the Seller Permits shall have been validly assigned

enforceable  by Buyer subject to  administrative  powers of regulatory  agencies
having jurisdiction.

2.1.7.  Intellectual  Property.  The Seller  Intellectual  Property  is owned or

Intellectual  Property by Seller did not,  infringe,  misappropriate or conflict
with  the  intellectual  property  rights  of  others.  Neither  Seller  nor the

conflict with the intellectual  property rights of others in connection with the
use by Seller of the Seller Intellectual Property.

2.1.8.  Necessary  Consents.  Seller has  obtained  and  delivered  to Buyer all
consents to  assignment  or waivers  thereof  required  to be obtained  from any
governmental  authority  or from any  other  third  party  in  order to  validly
transfer the Assets  hereunder,  including the  assignment of the Seller Permits
and the Transferred Contracts.

2.1.9.  Employees.  Schedule 2.1.10 hereto is a complete and accurate listing of
all  employees  of  Seller  that  are  involved  in  the  ownership,  operation,
maintenance  or  use  of  the  Assets  or  the  conduct  of  the  Business  (the
AEmployees@).  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.

2.1.10.   Investigations;   Litigation.   No  investigation  or  review  by  any
governmental   entity  with  respect  to  Seller  or  any  of  the  transactions
contemplated  by this  Agreement or the Seller  Agreements is pending or, to the
best  of  Seller=s  knowledge,  threatened,  nor  has  any  governmental  entity
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.

2.1.11. Absence of Certain Business Practices.  Neither Seller, the Shareholders
nor any officer, employee or agent of Seller, nor any other person acting on its
or his behalf, has, directly or indirectly, within the past five years, given or
agreed to give any gift or similar benefit to any customer, 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  Ainsolvent@  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 Adebts@ includes any legal liability  whether matured
or unmatured, liquidated or unliquidated, absolute fixed or contingent, disputed
or undisputed or secured or unsecured.

2.1.13. Untrue Statements. Seller has made available to Buyer true, 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.

2.1.14.  Finder=s  Fee.  All  negotiations  relative to this  Agreement  and the
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.

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 business of Buyer.

obligations  of Buyer,  enforceable  (subject  to normal  equitable  principals)
against Buyer in accordance with their 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
performance of this Agreement and the Buyer  Agreements and the  consummation of
the  transactions  contemplated  hereby and thereby  will not  conflict  with or
result in a violation  or breach of any term or provision  of, nor  constitute a
default  under  (I) the  charter  or  bylaws  of  Buyer;  (ii)  any  obligation,
indenture,  mortgage, deed of trust, lease, contract or other agreement to which
Buyer is a party or by which  Buyer or its  properties  are bound;  or (iii) any
provision of any law,  rule,  regulation,  order,  permits,  certificate,  writ,
judgment,  injunction,  decree,  determination,  award or other  decision of any
court,  arbitrator or other governmental  authority to which Buyer or any of its
properties is subject.

directly  with  Seller,   the  Shareholders  and  their  counsel,   without  the
intervention  of any other  person  as the  result of any act of Buyer in such a
manner as to give rise to any valid claim against any of the parties  hereto for
any brokerage commission, finder=s fee or any similar payment.

                                   Article IV

                                 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, agents
and  stockholders,  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
attorneys= fees and expenses (collectively,  the ADamages@) 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.

5.2  Indemnification  by Buyer.  In addition to any other remedies  available to
Seller or  Shareholders  under this  Agreement,  or at law or in  equity,  Buyer
shall,  jointly  and  severally,   indemnify,   defend  and  hold  harmless  the
Shareholders,  Seller and its officers, directors,  employees and agents against
and with  respect to any and all Damages  that such  indemnities  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 Seller or the  Shareholders  by or on behalf of Buyer
under this Agreement.

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
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.

                                   Article VI

respective party or parties,  as the case may be, and shall also survive without

This Asset Sale Agreement  (this  "Agreement") is made and entered into on April
14, 1997 by and between  Drillers,  Inc., a Texas  corporation  ("Seller"),  and
WellTech Eastern, Inc. ("Buyer"), a wholly-owned subsidiary of Key Energy Group,
Inc.

                                R E C I T A L S:

1.  Seller owns land  drilling  rigs 450,  459 and 472 (the  "Rigs") and related
assets; and

2. Seller  desires to sell to Buyer,  and Buyer  desires to acquire from Seller,
the Rigs and certain related assets in  consideration of the payment by Buyer of
the purchase  price  provided for herein,  all upon the terms and subject to the
conditions hereinafter set forth.

                                    AGREEMENT

In  consideration  of the premises and of the  agreements  and  covenants of the
parties contained herein, it is hereby agreed as follows:

I.       Purchase and Sale of Assets.

1.1 Transfer of Assets.  On the terms and subject to the conditions set forth in
this  Agreement,  at the Closing (as  hereinafter  defined),  Seller shall sell,
convey,  assign,  transfer  and deliver to Buyer,  and Buyer shall  purchase and
acquire from Seller all of the assets listed on Exhibit A hereto (the "Assets").

1.2 Excluded Assets. It is expressly understood and agreed that the Assets shall
not include the assets listed on Exhibit B hereto (the "Excluded  Assets"),  and
that all right,  title and  interest in the  Excluded  Assets  shall remain with
Seller  and that Buyer  shall not make any claim to  ownership  of the  Excluded
Assets.

1.3  Instruments  of  Conveyance  and Transfer  and  Delivery of Assets.  At the
Closing,  Seller shall  deliver or cause to be delivered to Buyer a Bill of Sale
and Assignment  transferring all of Seller's right, title and interest in and to
the Assets,  in the form  attached  hereto as Exhibit C (the "Bill of Sale") and
all other  certificates of title and other documents in the possession of Seller
and required to convey to Buyer the legal and valid title to the Assets.  At the
Closing,  title to the Assets shall pass from Seller to Buyer upon  confirmation
by Seller's  bank of Buyer's  deposit of the Balance in Seller's bank account in
immediately  available funds. Buyer may take possession of the Assets as soon as
Seller has received the preceding confirmation from Seller's bank.

II.  Execution  and  Closing.  The closing (the  "Closing")  with respect to the
transactions provided for in this Agreement shall commence in Houston,  Texas at
12:00 p.m. EST on  Wednesday,  April 16, 1997 and finish upon the  completion of
the items provided in Section 1.3 hereof.

III.     Purchase Price; Transaction.

3.1 Purchase Price. As  consideration  for the Assets,  and subject to the terms
and conditions of this  Agreement,  Buyer shall deliver at the Closing to Seller
One  Million  Three  Hundred  and  Fifty   Thousand  and  NO/100  U.S.   Dollars
(US$1,350,000.00)  (the  "Balance")  through  a  wire  transfer  of  immediately
available funds deposited to Seller's bank account in Houston,  Texas, which sum
represents  the purchase  price of One Million Five Hundred  Thousand and NO/100
U.S.  Dollars  (US$1,500,000.00)  agreed to by the  parties  for the Assets (the
"Purchase Price"), less a One Hundred and Fifty Thousand and NO/100 U.S. Dollars
(US$150,000.00)  advance  payment made by Buyer to Seller on March 17, 1997 (the
"Advance  Payment").   In  the  event  that  Buyer  does  not  comply  with  the
Post-Closing   Conditions  (as  hereinafter  defined),   Seller  shall  have  no
obligation  to return any part of the  Purchase  Price and  Buyer's  obligations
under  Sections V and VI hereto shall remain in effect until Buyer  fulfills the
Post-Closing Conditions.

3.2 Affiliate  Transaction.  In connection  with the  transactions  contemplated
hereby, Seller shall cause its affiliate Drillers International, S.A. ("Drillers
International")  to execute with, and deliver to,  Servicios  Welltech,  S.A., a
partially-owned  subsidiary  of  Buyer  ("Welltech"),   a  separate  asset  sale
agreement  in the form  attached  hereto as  Exhibit D (the  "Argentine  Bill of
Sale")  conveying  title to Welltech of certain  additional  assets in Argentina
owned by Drillers  International  and listed in an exhibit to the Argentine Bill
of Sale (the "Affiliate Transaction").  Of the Purchase Price paid by Buyer, One
Hundred  and Fifty  Thousand  and 00/100  Dollars  (U.S.  $150,000.00)  shall be
allocated by the parties to the Affiliate Transaction.

3.3 Sales Taxes. The Buyer and Seller  acknowledge that no Texas state sales tax
is due or owing in  connection  with the  transfer of the Assets  under  Section
151.304 of the Texas Tax Code.  To the  extent  sales or  value-added  taxes are
determined to be due and owing in connection  with the Affiliate  Transaction or
the execution,  delivery or performance of this Agreement, either in the U.S. or
Argentina, Buyer shall be responsible for payment of any and all such taxes.

IV. Representations of Seller. Seller represents and warrants that the following
are true and  correct as of this date and will be true and  correct  through the
date of the Closing as if made on that date:

4.1  Organization  and Good Standing.  Seller is a corporation  duly  organized,
validly  existing and in good standing under the laws of the State of Texas with
all  requisite  power  and  authority  to carry on the  business  in which it is
engaged and to own the Assets.

4.2 Authorization and Validity. The execution,  delivery and performance of this
Agreement  and the  other  agreements  contemplated  hereby by  Seller,  and the
consummation of the transactions contemplated hereby and thereby, have been duly
authorized  by Seller.  This  Agreement  and each other  agreement  contemplated
hereby have been or will be duly executed and delivered by Seller and constitute
or will constitute legal, valid and binding  obligations of Seller,  enforceable
against  Seller in  accordance  with their  respective  terms,  except as may be
limited  by  applicable   bankruptcy,   insolvency  or  similar  laws  affecting
creditors' rights generally or the availability of equitable remedies.

4.3 No Violation. Neither the execution and performance of this Agreement or the
agreements   contemplated  hereby  nor  the  consummation  of  the  transactions
contemplated  hereby or  thereby  will  result in a  violation  or breach of the
Articles of Incorporation or Bylaws of Seller or, to Seller's knowledge, violate
or breach any  agreement or other  instrument  under which Seller is bound or to
which any of the Assets are subject,  or result in the creation or imposition of
any lien, charge or encumbrance upon any of such Assets.

4.4  Title to  Assets.  Seller  owns the  Assets  free and  clear of all  liens,
security interests, claims and encumbrances.

4.5  No  Representation   Regarding   Condition  of  Assets.   SELLER  MAKES  NO
REPRESENTATION  OR WARRANTY,  EITHER EXPRESS OR IMPLIED,  AS TO THE MAINTENANCE,
REPAIR,  CONDITION,  DESIGN OR  MARKETABILITY OF THE ASSETS  INCLUDING,  BUT NOT
LIMITED TO, ANY IMPLIED OR EXPRESS WARRANTY OF  MERCHANTABILITY OR FITNESS FOR A
PARTICULAR  PURPOSE,  IT BEING THE EXPRESS  AGREEMENT  OF BUYER AND SELLER THAT,
EXCEPT AS EXPRESSLY SET FORTH IN THIS AGREEMENT, BUYER WILL OBTAIN THE ASSETS IN
THEIR CONDITION AND STATE OF REPAIR AT THE CLOSING, "AS IS," AND "WHERE IS."

V.  Post-Closing  Matters.  As soon after the Closing as practicable,  but in no
event later than April 30, 1997, Buyer shall satisfy the following  requirements
(the "Post-Closing Conditions"):

5.1 Confirmation by Buyer in writing from the Argentine  customs  authority,  to
the reasonable satisfaction of the Seller, of the assignment and transfer of the
temporary importation permits and nationalization documents covering the Assets,
including,  but not limited to, the  presentation  of the  necessary  underlying
contractual  commitments  by Buyer in Argentina to third  parties to justify the
continued presence of the Rigs in Argentina;

5.2 Confirmation by Buyer in writing from the Argentine  customs  authority,  to
the  reasonable  satisfaction  of  the  Seller,  of  the  presentation  to,  and
acceptance in writing by, the Argentine customs authority of sufficient bonds or
other  financial  guaranties  by Buyer to cover the  Assets  and  authorize  the
release  of  any  financial   guaranties   established  by  Seller  or  Drillers
International, or any of their affiliates, to authorize the presence of the Rigs
in Argentina; and

5.3 Confirmation by Buyer in writing from the Argentine  customs  authority,  to
the  reasonable  satisfaction  of the Seller,  of the  release by the  Argentine
customs authority of the bonds or other financial  guaranties currently in place
by Seller.

VI. Yard  Rentals.  Seller  agrees that Buyer shall not assume any  liability or
obligation from Seller's real property lease (the "Seller  Lease")  covering the
real property (the "Seller Real  Property") on which the Assets and the Excluded
Assets are located on the date hereof,  or any other  liabilities  other than as
provided herein. Following the Closing, Seller agrees to promptly provide notice
of the  termination of the Seller Lease to its lessor  thereunder,  which Seller
represents (and Buyer acknowledges) shall cause the Seller Lease to terminate on
the sixtieth  (60th) day  following  such  lessor's  receipt of the  termination
notice (the "Seller  Lease  Termination  Date").  From the date hereof until the
Seller Lease  Termination  Date, Buyer shall have the right to occupy (and store
the Assets on) the Seller Real Property.  In return for such right,  Buyer shall
reimburse  Seller for its rental payments,  and other occupancy  costs,  owed by
Seller  pursuant to the Seller Lease (but excluding any  termination  penalties)
from the date that it removes the Excluded  Assets from the Seller Real Property
until the Seller Lease Termination Date.

VII. Indemnification.  Buyer hereby agrees to indemnify and hold Seller harmless
from and against all manner of action, causes of action,  claims,  counterclaims
or third party actions, controversies,  agreements, promises, damages, expenses,
claims and  demands  whatsoever,  in law, in equity or  otherwise,  arising as a
result of, or in  connection  with (a) the  ownership,  use or  operation of the
Assets,  or the use of Seller  Real  Property,  after the  Closing;  (b) Buyer's
failure to fulfill its obligations under Section V above; or (c) Buyer's conduct
of its businesses on or after the Closing. Seller hereby agrees to indemnify and
hold Buyer  harmless  from and against  all manner of action,  causes of action,
claims,  counterclaims  or  third  party  actions,  controversies,   agreements,
promises, damages, expenses, claims and demands whatsoever, in law, in equity or
otherwise,  arising  as a result  of, or in  connection  with (a) any  breach by
Seller of its  representations,  warranties,  covenants or agreements  set forth
herein or in any certificate, schedule, exhibit or other instrument delivered or
furnished  to Buyer in  connection  herewith;  (b)  Seller's  ownership,  use or
operation  of the Assets prior to the  Closing;  or (c) Seller's  conduct of its
businesses on or after the Closing.

VIII.  Notices.  Any notice,  consent,  or other communication to be given under
this  Agreement by any party to any other party shall be in writing and shall be
either (a)  personally  delivered,  (b) mailed by registered or certified  mail,
postage prepaid with return receipt  requested,  delivered by overnight  express
delivery service or same-day local courier service, or (d) delivered by telex or
facsimile  transmission  to the address set forth  beneath the  signature of the
parties,  or at such other address as may be designated by the parties from time
to time in  accordance  with this  Section.  Notices  delivered  personally,  by
overnight  express  delivery service or by local courier service shall be deemed
given as of actual receipt.  Mailed notices shall be deemed given three business
days after mailing.  Notices delivered by telex or facsimile  transmission shall
be deemed given upon receipt by the sender of the  answerback  (in the case of a
telex) or transmission confirmation (in the case of a facsimile transmission).

IX. Further  Assurances.  At the Closing,  and at all times thereafter as may be
reasonably  necessary,  Seller  shall  execute  and  deliver to Buyer such other
instruments of transfer as shall be reasonably  necessary or appropriate to vest
in Buyer  good and  indefeasible  title to the  Assets  and to  comply  with the
purposes  and  intent of this  Agreement,  including,  but not  limited  to, the
execution by Seller of those documents,  certificates and assignments reasonably
requested  by Buyer to  facilitate  the  transfer of any  customs  documentation
allowing for the presence of the Assets in Argentina. At the Closing, and at all
times thereafter as may be necessary,  Buyer shall execute and deliver to Seller
such other  instruments  as shall be  reasonably  necessary  or  appropriate  to
evidence the assumption by Buyer of the  responsibility for the Yard Rentals (as
defined in Article VI).

X. Governing  Law. The parties hereto hereby agree that this Agreement  shall be
governed by, and  construed  and enforced in  accordance  with,  the laws of the
State of Texas,  notwithstanding  its conflict or choice of law principles.  The
parties hereto further acknowledge that, in the event that Texas' choice of laws
rules  were to apply in  connection  with such  choice  of law,  (I) Texas has a
substantial relationship to the parties hereto and the transactions contemplated
hereby,  and (ii)  there is a  reasonable  basis for the  choice of law.  If any
action is brought to enforce or interpret this Agreement,  venue for such action
shall be in Harris County, Texas.

XI.  Miscellaneous.  This Agreement and the other documents  contemplated herein
supersede all other  agreements,  oral or written,  between or among the parties
hereto  with  respect  to the  subject  matter  hereof  and  contain  all of the
covenants and agreements between the parties with respect thereto. Any amendment
or  modification  of this Agreement shall be valid only if in writing and signed
by both parties  hereto.  Each party to this Agreement shall perform any and all
further acts and execute and deliver any and all documents and instruments  that
may be reasonably necessary to carry out the provisions of this Agreement.  This
Agreement may be executed by facsimile  signature and in  counterparts,  each of
which shall  constitute an original,  but all of which shall  constitute one and
the same  document.  This  Agreement and the rights,  interests and  obligations
hereunder  shall be binding  upon and shall  inure to the benefit of the parties
hereto and their  respective  heirs,  personal  representatives,  successors and
assigns.  If any  provision  of this  Agreement  is held to be void,  illegal or
unenforceable  under  present or future laws  effective  during the term hereof,
such provision  shall be fully  severable and this Agreement  shall be construed
and enforced as if such void, illegal or unenforceable provision never comprised
a part hereof,  and the remaining  provisions of this Agreement  shall remain in
full force and effect and shall not be affected in any way by the void,  illegal
or  unenforceable  provision or by its severance.  Furthermore,  in lieu of such
severed provision,  there shall be added automatically as part of this Agreement
a provision as similar in its terms to such severed provision as may be possible
and be valid, legal and enforceable.

IN WITNESS  WHEREOF,  the  parties  hereto  have  executed  and  delivered  this
Agreement on the date first above written.

                                    Article I

                           Purchase and Sale of Assets

                         Representations and Warranties
                        of the Seller and the Shareholder

II.1  Representations and Warranties of the Seller and the Shareholder.  Each of

organization,  has full requisite  corporate power and authority to carry on its

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.

II.1.2.  Agreements  Authorized  and  their  Effect  on Other  Obligations.  The
execution and delivery of this Agreement  have been  authorized by all necessary
corporate and shareholder  action on the part of the Seller and the Shareholder,
and this  Agreement  is the valid and binding  obligation  of the Seller and the
Shareholder enforceable (subject to normal equitable principles) against each of
such  parties 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
performance  of  this  Agreement  and  the   consummation  of  the  transactions
contemplated  hereby,  will not conflict with or result in a violation or breach
of any term or provision  of, nor  constitute a default under (i) the charter or
bylaws (or other  organizational  documents)  of the Seller or the  Shareholder,
(ii) any obligation,  indenture,  mortgage,  deed of trust,  lease,  contract or
other  agreement to which the Seller or the  Shareholder  is a party or by which
the Seller or the Shareholder or their respective properties are bound; or (iii)
any provision of any law, rule, regulation, order, permits,  certificate,  writ,
judgment,  injunction,  decree,  determination,  award or other  decision of any
court,  arbitrator,  or other governmental  authority to which the Seller or the
Shareholder or any of their respective properties are subject.

II.1.3.  Contracts.  There are no contracts in effect which relate to the Assets
and Buyer  shall  have the right to own and  operate  the  Assets  free from any
contractual  obligations  entered into by Seller or Shareholder.  To the best of
their  knowledge,  neither  the  Seller nor the  Shareholder  has  received  any
information  which  would  cause  either of such  parties to  conclude  that any
customer  of the Seller  will (or is likely to) cease  doing  business  with the
Seller

II.1.4. Title to and Condition of Assets. The Seller has good,  indefeasible and
marketable  title  to all of the  Assets,  free and  clear  of any  Encumbrances
(defined below). Buyer has had the opportunity to inspect the Assets and neither
Seller nor  Shareholder  makes any  warranty  concerning  the  condition of said
Assets,  the sale hereunder  being AS IS, WHERE IS with respect to the condition
of the Assets.  All of the Assets conform to all applicable laws governing their
use. No notice of any violation of any law,  statute,  ordinance,  or regulation
relating  to  any  of  the  Assets  has  been  received  by  the  Seller  or the
Shareholder,   except  such  as  have  been  fully   complied   with.  The  term
"Encumbrances" means all liens, security interests, pledges, mortgages, deeds of
trust,  claims,  rights of first  refusal,  options,  charges,  restrictions  or
conditions  to transfer or  assignment,  liabilities,  obligations,  privileges,
equities, easements, rights of way, limitations, reservations, restrictions, and
other encumbrances of any kind or nature.

II.1.5.  Licenses and Permits.  There are no licenses or permits necessary under
law or otherwise  for the  operation,  maintenance  and use of the Assets in the
manner in which they are now being operated, maintained and used.

II.1.6.  Financial  Statements.  The Seller  has  delivered  to Buyer  copies of
certain unaudited financial  statements of Seller,  copies of which are attached
hereto as Schedule 2.1.7 (collectively,  the "Seller Financial  Statements") and
include an unaudited balance sheet (the Unaudited Balance Sheet") as of December
31, 1996 (the "Balance Sheet Date").  The Seller Financial  Statements are true,
correct and complete in all material  respects and present  fairly and fully the
financial  condition of the Seller as at the dates and for the periods indicated
thereon, and have been prepared in accordance with generally accepted accounting
principles  as  promulgated  by  the  American  Institute  of  Certified  Public
Accountants  ("GAAP")  applied on a consistent  basis,  except as noted therein.
Each of the  Seller  Financial  Statements  include  all  adjustments  which are
necessary for a fair  presentation of the applicable  Seller's  results for that
period.  The inventories of the Seller reflected in the Unaudited Balance Sheet,
or which have  thereafter  been  acquired by the  Seller,  consist of items of a
quality and quantity  salable in the normal course of the  applicable  Business.
The values at which such  inventories  are carried are in  accordance  with GAAP
applied on a consistent  basis,  and are  consistent  with the normal  inventory
level and practices of the Seller with respect to the Business.

II.1.7.  Absence of Certain  Changes and  Events.  Other than as a result of the
transactions contemplated by this Agreement, since the Balance Sheet Date, there
has not been:
(a)  Financial  Change.  Any  adverse  change  in the  Assets  or the  financial
condition, operations, liabilities or prospects of the Seller;

(b)  Property  Damage.  Any  damage,  destruction,  or loss to any of the Assets
(whether or not covered by insurance);

(c)  Waiver.  Any waiver or release of a material  right of or claim held by the
Seller;

(d) Change in  Assets.  Any  acquisition,  disposition,  transfer,  encumbrance,
mortgage,  pledge or other  encumbrance of any asset of the Seller other than in
the ordinary course of business;

(e) Labor Disputes. Any labor disputes between the Seller and its employees; or

(f) Other  Changes.  Any other  event or  condition  known to the  Seller or the
Shareholder  that  particularly  pertains  to and has or might  have an  adverse
effect on the Assets or the financial condition or prospects of the Seller.

II.1.8.  Necessary Consents.  The Seller has obtained and delivered to Buyer all
consents to  assignment  or waivers  thereof  required  to be obtained  from any
governmental  authority  or from any  other  third  party  in  order to  validly
transfer  the Assets  hereunder,  including,  without  limitation,  any consents
required to assign the Contracts or the Seller Permits.

II.1.9.  Environmental  Matters.  None of the current or past  operations of the
Assets is being or has been  conducted or used in such a manner as to constitute
a violation of any Applicable  Environmental  Laws (defined below).  Neither the
Seller nor the  Shareholder has received any notice (whether formal or informal,
written or oral) from any entity,  governmental  agency or individual  regarding
any  existing,  pending  or  threatened  investigation  or  inquiry  related  to
violations  of any  Applicable  Environmental  Laws or regarding  any claims for
remedial  obligations  or  contribution  for removal  costs or damages under any
Applicable Environmental Laws. There are no writs, injunction decrees, orders or
judgments  outstanding,  or  lawsuits,  claims,  proceedings  or  investigations
pending  or,  to the  knowledge  of the  Seller or the  Shareholder,  threatened
relating to the ownership,  use,  maintenance or operation of the Assets nor, to
the  knowledge of the Seller or the  Shareholder,  is there any basis for any of
the foregoing.  Buyer is not required to obtain any permits, licenses or similar
authorizations pursuant to any Applicable Environmental Laws in effect as of the
date hereof to operate  and use any of the Assets for their  current or proposed
purposes and uses. To the knowledge of either the Seller or the Shareholder, the
Assets include all environmental  and pollution control equipment  necessary for
compliance  with all  Applicable  Environmental  Laws.  No  Hazardous  Materials
(defined  below)  have been or are  currently  being  used by the  Seller in the
operation  of  the  Assets.  No  Hazardous  Materials  are  or  have  ever  been
incorporated into any of the Assets.  The term "Applicable  Environmental  Laws"
means any applicable  federal,  state or local law,  statute,  ordinance,  rule,
regulation,  order  or  notice  requirement  pertaining  to  human  health,  the
environment,  or to the storage,  treatment,  discharge,  release or disposal of
hazardous wastes or hazardous substances,  including, without limitation (i) the
Comprehensive Environmental Response, Compensation and Liability Act of 1980 (42
U.S.C.  ss.ss.9601 et seq.),  as amended from time to time,  including,  without
limitation,  as amended pursuant to the Superfund Amendments and Reauthorization
Act of  1986  ("CERCLA"),  and  regulations  promulgated  thereunder,  (ii)  the
Resources Conservation and Recovery Act of 1976 (42 U.S.C.  ss.ss.6901 et seq.),
as amended from time to time ("RCRA"), and regulations  promulgated  thereunder,
(iii) the Federal Water  Pollution  Control Act (U.S.C.A.  ss.9601 et seq.),  as
amended, and regulations promulgated  thereunder,  and (iv) any applicable state
laws or regulations relating to the environment.  The term "Hazardous Materials"
means (x) asbestos,  polychlorinated  biphenyls,  urea formaldehyde,  lead based
paint, radon gas, petroleum, oil, solid waste, pollutants and contaminants,  and
(y) any chemicals,  materials, wastes or substances that are defined, regulated,
determined or identified as toxic or hazardous in any  Applicable  Environmental
Laws,   including,   but  not  limited  to,  substances  defined  as  "hazardous
substances,"  "hazardous  materials," or "hazardous waste" in CERCLA,  RCRA, the
Hazardous  Materials  Transportation  Act (49  U.S.C.  ss.  1801,  et seq.),  or
comparable  state  and  local  statutes  or  in  the  regulations   adopted  and
publications promulgated pursuant to said statutes.

II.1.10. No ERISA Plans or Labor Issues. No employee benefit plan of the Seller,
whether or not  subject to any  provisions  of the  Employee  Retirement  Income
Security Act of 1974, as amended,  will by its terms or applicable  law,  become
binding upon or an obligation of Buyer. The Seller has not engaged in any unfair
labor  practices  which  could  reasonably  be  expected to result in a material
adverse  effect on the Assets.  The Seller does not have any dispute with any of
its  existing or former  employees,  and there are no labor  disputes or, to the
knowledge of the Seller or the Shareholder,  any disputes  threatened by current
or former employees of any of the Seller.

II.1.11.   Investigations;   Litigation.  No  investigation  or  review  by  any
governmental  entity  with  respect  to the  Seller  or any of the  transactions
contemplated  by this Agreement is pending or, to the knowledge of the Seller or
the Shareholder, threatened, nor has any governmental entity indicated to either
the Seller or the  Shareholder  an  intention  to conduct the same.  There is no
suit,  action,  or legal,  administrative,  arbitration,  or other proceeding or
governmental investigation pending to which either the Seller or the Shareholder
is a party or, to the knowledge of either the Seller or the  Shareholder,  might
become a party or which particularly affects the Assets.

II.1.12.  Absence of Certain  Business  Practices.  Neither the Seller,  nor any
officer of the Seller, nor to the best of Seller's knowledge,  employee or agent
of the Seller, or any other person acting on behalf of any of the Seller,  have,
directly or indirectly,  within the past five years, given or agreed to give any
gift or similar benefit to any customer, 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 to assist the 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 if not continued in the future,
might materially adversely affect the profitable use of the Assets.

II.1.13. Solvency. The Seller is not presently insolvent, nor will the Seller be
rendered  insolvent by the occurrence of the  transactions  contemplated by this
Agreement. The term "insolvent", with respect to a particular Seller, means that
the sum of the present fair and saleable value of such 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.

II.1.14. Untrue Statements.  This Agreement and all other agreements executed by
the Seller or the Shareholder and delivered to Buyer does not contain any untrue
statement  of a material  fact or omit to state a material  fact  required to be
stated  therein or necessary  to make the  statements  therein,  in light of the
circumstances  under which they were made, not  misleading.  The Seller has also
made  available  to Buyer  true,  complete  and  correct  copies of all lists of
suppliers  and  customers,   and  records  relating  to  the  Assets,  and  such
information covers all commitments and liabilities of Buyer relating principally
to the Assets.

II.1.15.  Finder's  Fee. All  negotiations  relative to this  Agreement  and the
transactions  contemplated  hereby  have  been  carried  on by the  Seller,  the
Shareholder 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.

                                   Article III

                              Additional Agreements

III.1 Noncompetition. Except as otherwise consented to or approved in writing by
Buyer,  each of the  Seller  and the  Shareholder  agree that for a period of 60
months following the date hereof,  such party will not,  directly or indirectly,
acting alone or as a member of a  partnership  or a 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 business in competition with the business or businesses
conducted  by the Seller on the date hereof or by Buyer (or Buyer's  affiliates)
on the date  hereof,  or in any  service  business  the  services  of which  are
provided  and  marketed by the Seller on the date hereof or by Buyer (or Buyer's
affiliates) on the date hereof in the following states: West Virginia, Virginia,
Kentucky,   Ohio,   Pennsylvania,   New  York,   Maryland   and   Indiana   (the
"Non-Competition Territory"); (ii) request any present customers or suppliers of
the Seller to curtail or cancel their business with Buyer; (iii) disclose to any
person,  firm or corporation any trade,  technical or  technological  secrets of
Buyer  (or  Buyer's  affiliates)  or of the  Seller  or  any  details  of  their
organization or business affairs or (iv) induce or actively attempt to influence
any employee of Buyer (or Buyer's affiliates) to terminate his employment. Buyer
acknowledges that Seller owns oil and gas wells and is engaged in the production
of oil and gas  therefrom.  Nothing  contained  herein  shall  be  construed  to
prohibit  Seller or  Shareholder  from  continuing to engage in said oil and gas
production within the Non-Competition Territory and from servicing only such oil
and gas wells owned by Seller or Shareholder;  provided  however that Seller and
Shareholder agree that any equipment acquired or leased by Seller or Shareholder
for the purpose of servicing Seller or Shareholder's  oil and gas wells shall be
used exclusively for the purpose of servicing Seller or Shareholder's  wells and
not for wells  owned by others or for  compensation.  Each of the Seller and the
Shareholder  agree that if either the length of time or geographical area as 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 Seller and the  Shareholder  may have under the
laws  of  any  state  requiring  a  corporation  selling  its  assets  (and  the
shareholders  of such  corporation) to limit its activities so that the goodwill
and business relations being transferred with such assets will not be materially
impaired.  Each of the Seller and the Shareholder  further agree and acknowledge
that Buyer does not have any adequate remedy at law for the breach or threatened
breach by the  Seller or the  Shareholder  of the  covenants  contained  in this
Section 3.1, and agree that Buyer may, in addition to the other  remedies  which
may be available to it hereunder,  file a suit in equity to enjoin the Seller or
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. Each of the Seller and the Shareholder
acknowledges that the covenants set forth in this Section 3.1 are being executed
and delivered by such party in consideration of the covenants of Buyer contained
in this Agreement, and for other good and valuable consideration, the receipt of
which is hereby acknowledged.

III.2 Hiring  Employees.  Schedule 3.2 hereto is a complete and accurate listing
of all  employees  of the Seller that  devote  their full time and effort in the
operation  of the Assets  and the  conduct of the  Business  (the  "Employees").
Effective as of the date hereof, all of the Employees shall be terminated by the
Seller  and,  subject to such  Employees  meeting  Buyer's  standard  employment
eligibility  requirements,  hired by Buyer.  Buyer  shall have no  liability  or
obligation  with respect to any employee  benefits of any Employee  except those
benefits that accrue  pursuant to such  Employees'  employment  with Buyer on or
after the date hereof.  Each of the Seller and the  Shareholder  shall cooperate
with  Buyer  in  connection  with  any  offer of  employment  from  Buyer to the
employees  and use its best efforts to cause the  acceptance of any and all such
offers. All Employees hired by Buyer shall be at-will employees of Buyer.

III.3  Allocation of Purchase  Price.  The parties  hereto agree to allocate the
purchase  price paid by Buyer for the Assets  hereunder as set forth on Schedule
3.3 hereto, and shall report this transaction for federal income tax purposes in
accordance with the allocation so agreed upon. The parties hereto for themselves
and for their  respective  successors  and assigns  covenant and agree that they
will file  coordinating  Form  8594's in  accordance  with  Section  1060 of the
Internal  Revenue Code of 1986,  as amended,  with their  respective  income tax
returns for the taxable year that includes the date hereof.

III.4 Additional Non-Competition Agreements. The parties acknowledge that Seller
intends to give certain  consideration to each of the following persons from the
consideration received from Buyer: Timothy Wilson, Thomas Wilson, William Shreve
II,  Christopher  Shreve and Kevin  Shreve.  Buyer's  obligations  hereunder are
expressly  conditioned  upon  the  execution  of those  certain  Non-Competition
Agreements between Buyer and Timothy Wilson,  Thomas Wilson,  William Shreve II,
Christopher  Shreve and Kevin Shreve and Seller and Shareholder  agree that they
shall deliver to Buyer within 30 days hereof executed Non-Competition Agreements
between Buyer and each of the individuals named in this Section III.4.

III.5 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
effect the transactions contemplated hereby.

                                   Article IV

                                 Indemnification

IV.1 Indemnification by the Seller and the Shareholder. In addition to any other
remedies available to Buyer under this Agreement,  or at law or in equity,  each
of the Seller and the  Shareholder  shall,  jointly  and  severally,  indemnify,
defend and hold harmless Buyer and its officers,  directors,  employees,  agents
and  stockholders,  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
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 either the Seller or the Shareholder 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 the Seller or the Shareholder under this Agreement; and (ii) the Seller
Liabilities.

IV.2  Indemnification  Procedure.  If any party  hereto  discovers  or otherwise
becomes  aware of an  indemnification  claim  arising  under Section 4.1 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.

                                    Article V

                                  Miscellaneous

V.1 Survival of Representations,  Warranties and Covenants. All representations,
warranties,  covenants and  agreements  made by the parties hereto shall survive
indefinitely without limitation, notwithstanding any investigation made by or on
behalf  of  any  of  the  parties  hereto.  All  statements   contained  in  any
certificate,  schedule,  exhibit or other instrument  delivered pursuant to this
Agreement  shall be deemed to have been  representations  and  warranties by the
respective party or parties,  as the case may be, and shall also survive without
limitation despite any investigation made by any party hereto or on its behalf.

V.2 Entirety.  This Agreement  embodies the entire  agreement  among the parties
with respect to the subject matter hereof,  and all prior agreements between the
parties with respect thereto are hereby superseded in their entirety.

V.3 Notices and  Waivers.  Any notice or waiver to be given to any party  hereto
shall be in  writing  and  shall be  delivered  by  courier,  sent by  facsimile
transmission  or first class  registered  or certified  mail,  postage  prepaid,
return receipt requested.

representations,  warranties, covenants and agreements, and subject to the terms

                                    Article I

forth in this  Agreement,  the Sellers hereby agree to sell,  convey,  transfer,

collectively herein as the "Assets"):

Sellers  shall  execute  and  deliver  to Buyer  Bills  of Sale  and  Assignment

                                   Article II

                         Representations and Warranties
                                 of the Sellers

II.1 Representations and Warranties of the Sellers.  Each of the Sellers jointly
and severally represents and warrants to Buyer as follows:

II.1.1. Organization and Good Standing.  Petro-Equipment,  Inc. is a corporation
duly  organized,  validly  existing and in good  standing  under the laws of its
state of organization, 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.

II.1.2.  Agreements  Authorized  and  their  Effect  on Other  Obligations.  The
execution and delivery of this Agreement  have been  authorized by all necessary
corporate and shareholder action on the part of the Sellers,  and this Agreement
is the valid and  binding  obligation  of the  Sellers  enforceable  (subject to
normal equitable principles) against each of such parties 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  performance of this Agreement and the
consummation of the transactions  contemplated hereby, will not conflict with or
result in a violation  or breach of any term or provision  of, nor  constitute a
default under (i) the charter or bylaws (or other  organizational  documents) of
the Sellers,  (ii) any obligation,  indenture,  mortgage,  deed of trust, lease,
contract or other  agreement  to which one or both of the Sellers may be a party
or by which the Sellers or their  respective  properties are bound; or (iii) any
provision of any law,  rule,  regulation,  order,  permits,  certificate,  writ,
judgment,  injunction,  decree,  determination,  award or other  decision of any
court,  arbitrator,  or other governmental authority to which the Sellers or any
of their respective properties are subject.

II.1.3.  Title to and Condition of Assets.  The Sellers have good,  indefeasible
and marketable  title to all of the Assets,  free and clear of any  Encumbrances
(defined below). Buyer has had the opportunity to inspect the Assets and Sellers
make no warranty  concerning  the condition of said Assets,  the sale  hereunder
being AS IS, WHERE IS with respect to the condition of the Assets.  No notice of
any violation of any law, statute,  ordinance,  or regulation relating to any of
the Assets has been  received  by the  Sellers,  except  such as have been fully
complied  with. The term  "Encumbrances"  means all liens,  security  interests,
pledges,  mortgages,  deeds of trust, claims, rights of first refusal,  options,
charges,  restrictions  or  conditions to transfer or  assignment,  liabilities,
obligations,  privileges,  equities,  easements,  rights  of  way,  limitations,
reservations, restrictions, and other encumbrances of any kind or nature.

II.1.4.  Legal  Right to  Convey.  The  Sellers  have  acquired  the  Assets  in
accordance  with all  applicable  laws and have the legal  right to  convey  the
Assets to Buyer and no other  person or entity has or will have any claim to the
Assets  nor has or will have the  right to void the  transfers  and  conveyances
hereunder for any reason  including any proceeding  commenced  under the laws of
any state or the United States  Bankruptcy Code. The  transactions  contemplated
hereby are not and will not become subject to any valid and  enforceable  claims
of any third party,  including any claims of a bankruptcy trustee.  Sellers have
not received  notice of any pending or threatened  claim by any person or entity
to the Assets.  At Closing,  Buyer  shall have the  absolute  right to the quiet
possession and use of the Assets.

II.1.5. Necessary Consents. The Sellers have obtained and delivered to Buyer all
consents to  assignment  or waivers  thereof  required  to be obtained  from any
governmental  authority  or from any  other  third  party  in  order to  validly
transfer the Assets hereunder.

II.1.6.  Investigations;  Litigation.  There  is  no  suit,  action,  or  legal,
administrative,  arbitration,  or other proceeding or governmental investigation
pending to which either of the Sellers is a party or, to the knowledge of either
the Sellers, might become a party or which particularly affects the Assets.

II.1.7. Solvency.  Neither Seller is presently insolvent, nor will either Seller
be rendered insolvent by the occurrence of the transactions contemplated by this
Agreement. The term "insolvent", with respect to a particular Seller, means that
the sum of the present fair and saleable value of such 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.

II.1.8. Untrue Statements. To the best of Sellers' knowledge, this Agreement and
all other  agreements  executed by the Sellers and  delivered  to Buyer does not
contain any untrue statement of a material fact or omit to state a material fact
required to be stated  therein or necessary to make the statements  therein,  in
light of the circumstances under which they were made, not misleading; provided,
however,  that  Sellers  acknowledge  and agree that their  representations  and
warranties  in Sections  II.1.3 and II.1.4 are  absolute  and  unqualified.  The
Sellers have also made  available to Buyer true,  complete and correct copies of
all  contracts,   documents   concerning   all  litigation  and   administrative
proceedings,   licenses,  permits,  insurance  policies,  and  records  relating
principally  to the Assets,  and such  information  covers all  commitments  and
liabilities of Buyer relating principally to the Assets.

II.1.9.  Finder's  Fee.  All  negotiations  relative to this  Agreement  and the
transactions  contemplated  hereby have been carried on by the Sellers 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.

II.2 Reliance.  Sellers  expressly agree and  acknowledge  that Buyer is relying
upon  Sellers'  representations  and  warranties  contained  herein,  that  said
representations and warranties are material and that absent such representations
and warranties that Buyer would not enter into this Asset Purchase Agreement and
the transactions contemplated herein.

                                   Article III

                              Additional Agreements

III.1 Noncompetition. Except as otherwise consented to or approved in writing by
Buyer,  each of the Sellers and William  Patrick Burr agree that for a period of
60  months  following  the  date  hereof,  such  party  will  not,  directly  or
indirectly,  acting  alone or as a member of a  partnership  or a 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 business providing logging,  perforating
or electric  wireline services or own, operate or lease a complete service truck
for use in the well  service or  wireline  service  business  in West  Virginia,
Virginia,  Kentucky,  Ohio,  Pennsylvania,  New York,  Maryland and Indiana (the
"Non-Competition Territory"); (ii) request any present customers or suppliers of
Young  Wireline  Services,  Inc. or  customers  or  suppliers  of the Sellers to
curtail or cancel their business with Buyer; (iii) disclose to any person,  firm
or  corporation  any  trade,  technical  or  technological  secrets of Buyer (or
Buyer's  affiliates) or of the Sellers or any details of their  organization  or
business affairs or (iv) induce or actively attempt to influence any employee of
Buyer (or Buyer's  affiliates) to terminate his employment;  provided,  however,
that nothing  contained herein shall be construed to prevent Sellers from owning
Superior  Micro System and  continuing to operate  Superior  Micro System in the
businesses  in which it is operated as of the date hereof,  nor shall Sellers be
prevented  from leasing a complete  full service  truck to a competitor of Buyer
who has been in existence for at least five years prior to the date hereof for a
lease term not to exceed  ninety (90) days,  which lease term cannot be extended
or  renewed,  provided  such  business  is not owned by any former  employee  of
Hitwell Surveys,  Inc., Young Wireline Service,  Inc., or Titan Surveys. Each of
the Sellers and William Patrick Burr agrees that if either the length of time or
geographical  area as set forth in this Section III.1 is deemed too  restrictive
in any court  proceeding,  the court may reduce such restrictions to those which
it deems  reasonable  under the  circumstances.  Each of the Sellers and William
Patrick  Burr  further  agrees  and  acknowledges  that  Buyer does not have any
adequate  remedy at law for the breach or  threatened  breach by the  Sellers or
William Patrick Burr of the covenants contained in this Section III.1, and agree
that Buyer may, in addition to the other  remedies  which may be available to it
hereunder,  file a suit in equity to enjoin the Sellers or William  Patrick Burr
from such breach or threatened  breach.  If any provisions of this Section III.1
are held to be invalid or against public policy, the remaining  provisions shall
not  be  affected  thereby.  Each  of  the  Sellers  and  William  Patrick  Burr
acknowledges  that the  covenants  set  forth in this  Section  III.1  are being
executed and delivered by such party in  consideration of the covenants of Buyer
contained in this Agreement, and for other good and valuable consideration,  the
receipt of which is hereby acknowledged.

III.2 Lease of Shop.  Sellers agree that they will cause J & D Rentals to extend
the lease  between J & D Rentals  and Young  Wireline  Services,  Inc.  for that
certain facility located at Old Rte 33 East,  Buckhannon,  West Virginia,  for a
period of thirty days upon  receipt of  $1,500.00.  During such  extension J & D
Rentals  shall grant Buyer the right to use such  premises,  to store any of the
Assets purchased  hereunder and to conduct such environmental  investigations or
assessment  as Buyer  deems  necessary.  If, in Buyer's  sole  discretion,  such
environmental reports are satisfactory, then Buyer and J & D Rentals shall enter
into a lease for such premises in the form attached hereto as Exhibit III.2.

III.3  Allocation of Purchase  Price.  The parties  hereto agree to allocate the
purchase  price paid by Buyer for the Assets  hereunder as set forth on Schedule
III.3 hereto,  and shall report this transaction for federal income tax purposes
in  accordance  with the  allocation  so agreed  upon.  The  parties  hereto for
themselves and for their  respective  successors and assigns  covenant and agree
that they will file  coordinating Form 8594's in accordance with Section 1060 of
the Internal Revenue Code of 1986, as amended,  with their respective income tax
returns for the taxable year that includes the date hereof.

III.4 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
effect  the  transactions  contemplated  hereby,  including  but not  limited to
certificates of title to any of the Assets which were not delivered at Closing.


                                   Article IV

                                 Indemnification

IV.1 Indemnification by the Sellers. In addition to any other remedies available
to Buyer  under  this  Agreement,  or at law or in equity,  each of the  Sellers
shall, jointly and severally,  indemnify, defend and hold harmless Buyer and its
officers,  directors,  employees,  agents  and  stockholders,  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 attorneys' fees and expenses  (collectively,
the "Damages") that such indemnitee shall incur or suffer,  which arise,  result
from or relate to any breach of, or failure by either of the Sellers 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 the Sellers under this  Agreement;  provided,  however,
that such  indemnity,  including  claims for breach of  warranty of title to the
Assets, shall not exceed the Purchase Price. Donald E. Clark ("Clark") expressly
assumes  and agrees to  indemnify  Buyer for any claim for  Damages  asserted by
Buyer hereunder  against Clark or against  Petro-Equipment,  Inc.. Clark further
agrees that Buyer may assert any claim for  indemnity  against  Petro-Equipment,
Inc.  directly against Clark without first asserting or exhausting any remedies,
it may have against  Petro-Equipment,  Inc.,  provided  that Clark's  Indemnity,
including  claims for breach of warranty of title to the Assets shall not exceed
the Purchase Price.

IV.2  Indemnification  Procedure.  If any party  hereto  discovers  or otherwise
becomes  aware of an  indemnification  claim  arising under Section IV.1 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 IV, 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.

                                    Article V

                                  Miscellaneous

V.1 Survival of Representations,  Warranties and Covenants. All representations,
warranties,  covenants and  agreements  made by the parties hereto shall survive
indefinitely without limitation, notwithstanding any investigation made by or on
behalf  of  any  of  the  parties  hereto.  All  statements   contained  in  any
certificate,  schedule,  exhibit or other instrument  delivered pursuant to this
Agreement  shall be deemed to have been  representations  and  warranties by the
respective party or parties,  as the case may be, and shall also survive without
limitation despite any investigation made by any party hereto or on its behalf.

V.2 Entirety.  This Agreement  embodies the entire  agreement  among the parties
with respect to the subject matter hereof,  and all prior agreements between the
parties with respect thereto are hereby superseded in their entirety.

V.3  Counterparts.  Any number of counterparts of this Agreement may be executed
and each such counterpart shall be deemed to be an original instrument,  but all
such counterparts together shall constitute but one instrument.

V.4 Notices and  Waivers.  Any notice or waiver to be given to any party  hereto
shall be in  writing  and  shall be  delivered  by  courier,  sent by  facsimile
transmission  or first class  registered  or certified  mail,  postage  prepaid,
return receipt requested.

advance of any  prepayment on the LIBOR Rate Loan  required  pursuant to Section

accrued, unpaid interest, shall be due and payable.

(c)  Interest on the Loan shall  accrue daily and shall be computed on the basis

than a Business Day, such payment shall be made on the next succeeding  Business
Day and such  extension of time shall be included in computing  any interest and
fees in respect of such payment, unless the result of such extension would be to
carry any Interest  Period  relating to a LIBOR Rate Loan into another  calendar
month in which event such Interest Period shall end on the immediately preceding
Business Day.

the amount of the requested increase (referred to herein as the "Redetermination
Fee").  The  parties   specifically  agree  that  the  Borrower  shall  pay  the
Redetermination  Fee to  Lender  regardless  of  whether  Lender  agrees  to the
increase in the Borrowing Base or whether the increase is actually funded.

ownership interests of the Borrower in the Mortgaged Properties that are subject

permitted under the Loan Agreement.  The Borrowing Base under the Loan is set at
the sum of $18,000,000.00. The Borrowing Base shall reduce on a monthly basis by

or in the amount of the Borrowing Base Reduction Amount.

redetermining the Borrowing Base, Lender shall determine the loan value which it
assigns to the oil and gas properties  that are proven  reserves,  developed and
producing  and that are  covered  by the Deeds of  Trust.  As to the oil and gas
properties,  the loan value  shall be based on Lender's  engineering  evaluation

factors, coverage percentage and appropriate risk factors.

either,   (i)  within  ten  (10)  business  days   thereafter,   by  instruments
satisfactory  in form and substance to Lender,  provide  Lender with  additional
Collateral with value in amounts satisfactory to Lender in order to increase the
Borrowing Base by an amount at least equal to such excess;  (ii) within ten (10)
business  days  thereafter,  prepay the  principal  of the Note  (together  with
accrued interest on the principal amount so prepaid) in an amount at least equal
to such excess;  or (iii)  amortize the overage by payments of six equal monthly
installments.

interpretation  or  administration  thereof,  has made it unlawful,  or that any
central bank or other  governmental  authority has asserted that it is unlawful,
for  Lender to make  LIBOR  Rate  Loans,  then,  on notice  thereof by Lender to
Borrower,  the  obligation of Lender to make LIBOR Rate Loans shall be suspended
until Lender shall have notified Borrower that the circumstances  giving rise to
such determination no longer exist.

(b) If Lender  shall  determine  that it is unlawful to maintain  any LIBOR Rate
Loan,  and,  if any LIBOR Rate  Loans are then  outstanding,  Lender  shall give
notice thereof to Borrower, and within three Business Days after receipt of such
notice Borrower shall elect either (A) to prepay in full all LIBOR Rate Loans of
Lender then outstanding,  together with interest accrued thereon,  either on the
last day of the  Interest  Period  thereof if Lender may  lawfully  continue  to
maintain  such LIBOR Rate Loans to such day, or  immediately,  if Lender may not
lawfully  continue to maintain such LIBOR Rate Loans,  together with any amounts
required to be paid in connection  therewith pursuant to this Agreement,  or (B)
to  immediately  convert such LIBOR Rate Loans to Base Rate Loans in  accordance
with Article II of this Agreement.

terminated,  Borrower may elect, by giving notice to Lender that all Loans which
would otherwise be made by Lender as LIBOR Rate Loans shall be instead Base Rate
Loans.

(a) If Lender shall determine that, due to either (i) the introduction of or any
change  (other  than any change by way of  imposition  of or increase in reserve
requirements  included  in the  calculation  of  the  LIBOR  Rate)  in or in the
interpretation  of any  law or  regulation  or  (ii)  the  compliance  with  any
guideline,  or request  from any central  bank or other  governmental  authority
(whether or not having the force of law) issued after  January 31,  1997,  there
shall be any  increase  in the cost to Lender  of  agreeing  to make or  making,
funding or  maintaining  any LIBOR Rate Loans (other than changes in the rate of
taxes on the  overall net income of  Lender),  then Lender  shall give notice of
such determination to Borrower,  and Borrower shall have the option either (iii)
to immediately  convert all  outstanding  LIBOR Rate Loans to Base Rate Loans in
accordance  with Article II or (iv) Borrower shall be liable for, and shall from
time to time,  upon  demand  therefor by Lender,  pay to Lender such  additional
amounts as are  sufficient to compensate  Lender for such  increased  costs.  If
Borrower elects to convert to Base Rate Loans,  it shall  nevertheless be liable
for any increased  costs incurred by Lender  regarding  LIBOR Rate Loans accrued
prior to the date of conversion.

(b) If Lender shall have  determined  that (i) the  introduction  of any capital
adequacy regulation,  (ii) any change in any capital adequacy regulation,  (iii)
any change in the  interpretation  or  administration  of any  capital  adequacy
regulation by any central bank or other governmental  authority charged with the
interpretation  or administration  thereof,  or (iv) compliance by Lender or any
corporation  controlling  the  Lender,  with any  capital  adequacy  regulation;
affects  or would  affect  the  amount of capital  required  or  expected  to be
maintained  by Lender or any  corporation  controlling  Lender and (taking  into
consideration  Lender's or such  corporations'  policies with respect to capital
adequacy and Lender's  desired return on capital)  determines that the amount of
such capital is increased as a consequence  of its  commitment to make the Loan,
credits or other obligations under this Agreement, then Lender shall give notice
of such determination to Borrower, and Borrower shall have the option either (v)
to immediately  convert all  outstanding  LIBOR Rate Loans to Base Rate Loans in
accordance  with  Article  II or (vi)  to pay to  Lender,  from  time to time as
specified by Lender, additional amounts sufficient to compensate Lender for such
increase.

4.3 - Funding  Losses.  Borrower  agrees to reimburse  Lender and to hold Lender
harmless  from  any loss or  expense  which  Lender  may  sustain  or incur as a
consequence of:

(a) The  failure of  Borrower to make any  payment or  mandatory  prepayment  of
principal of any LIBOR Rate Loan (including payments made after any acceleration
thereof);

(b) The failure of Borrower to borrow, continue or convert a Loan after Borrower
has  given (or is deemed to have  given) a Request  for  Advance  or a Notice of
Conversion/Continuation;

(c) The failure of Borrower to make any  prepayment  after  Borrower has given a
notice in accordance with Section 2.3;

(d) The prepayment (including pursuant to Section 2.3) of a LIBOR Rate Loan on a
day which is not the last day of the Interest Period with respect thereto; or

(e) The  conversion  pursuant to of any LIBOR Rate Loan to a Base Rate Loan on a
day that is not the last day of the respective  Interest  Period;  including any
such loss or expense  arising  from the  liquidation  or  reemployment  of funds
obtained by it to maintain  its LIBOR Rate Loans  hereunder or from fees payable
to terminate the deposits from which such funds were obtained.

4.4 - Inability to Determine Rates. If Lender shall have determined that for any
reason  adequate and reasonable  means do not exist for  ascertaining  the LIBOR
Rate for any  requested  Interest  Period with respect to a proposed  LIBOR Rate
Loan or that the LIBOR Rate  applicable for any requested  Interest  Period with
respect to a proposed LIBOR Rate Loan does not adequately and fairly reflect, in
Lender's  reasonable  judgment,  the cost to Lender of funding such Loan, Lender
shall forthwith give notice of such determination to Borrower.  Thereafter,  the
obligation of Lender to make or maintain  LIBOR Rate Loans,  as the case may be,
hereunder shall be suspended until Lender revokes such notice in writing, unless
means  exist for  ascertaining  the LIBOR Rate and  Borrower  agrees to pay such
amount as Lender determines in its sole and absolute  discretion is necessary to
reflect the cost of Lender of funding  such Loan.  Upon  receipt of such notice,
Borrower may revoke any Request for Advance or Notice of Conversion/Continuation
then  submitted by it. If Borrower  does not revoke such request or notice prior
to the time that such Loan is made,  Lender shall make,  convert or continue the
Loan, as proposed by Borrower in the amount specified in the applicable  request
or notice  submitted  by  Borrower,  but such Loan shall be made,  converted  or
continued as Base Rate Loans instead of LIBOR Rate Loans.

4.5 - Certificate  of Lender.  If Lender claims  reimbursement  or  compensation
pursuant to this  Article IV,  Lender  shall  deliver to Borrower a  certificate
setting forth in reasonable  detail the amount  payable to Lender  hereunder and
such  certificate  shall be binding on Borrower unless  Borrower  objects to the
contents of such certificate within five Business Days after receipt thereof. If
Borrower objects, Lender and Borrower shall attempt to resolve their differences
within 10 days,  and if  agreement  is not  reached  within such period then all
LIBOR Rate Loans shall be immediately converted to Base Rate Loans.

4.6 - Survival.  The agreements  and  obligations of Borrower in this Article IV
shall survive the payment of all other Obligations.

Interests and other properties shall be valid,  subsisting and in full force and
effect, and all rentals,  royalties and other amounts due and payable in respect

reorganization  or similar laws  affecting  creditors'  rights  generally,  upon
execution,  delivery and recording,  or filing, as appropriate,  the Loan Papers

on Schedule 7.9,  agreements,  documents and instruments  giving rise to Mineral
Interests,  farmout  agreements,  gas contracts,  hedging contracts,  Borrower's

terms of the Loan Papers cause Borrower to be, in default (nor has any potential
default  occurred)  under any Material  Agreement,  any  agreement,  document or
instrument giving rise to Mineral Interests,  farmout agreements,  gas contracts
or any  operating  or joint  operating,  or  unitization  agreements  related to
Mineral  Interests,  other than in each case such defaults or potential defaults
which could not, individually or collectively,  cause a Material Adverse Change;
and a default by  Borrower  under any  operating  or joint  operating  agreement
related  to any  Mineral  Interests  it owns  will  not  result  in any  loss or
diminution of any other Mineral Interests it owns.

7.10 - ERISA . Borrower has neither  terminated  a plan created  pursuant to the

Borrower is unaware of any fact or condition that might cause any of such rights
not to be renewed in due course.

partnership,  joint venture or association of any type  whatsoever  except those

environmental  law or  regulation  and there has not  heretofore  been filed any
complaint, nor commenced any administrative  procedure,  against Borrower or any
of  its  predecessors,   alleging  a  violation  of  any  environmental  law  or

regular business (oil and gas exploration and  production),  may use or generate
on a portion of its  properties  materials  which are  Hazardous  Materials,  as
hereinafter  defined.  Borrower has and will make a good faith attempt to comply
with all applicable statutes and regulations in the use, generation and disposal
of such  materials.  To the best of its  knowledge,  Borrower has not  otherwise
installed,  used,  generated,  stored or disposed of any hazardous waste,  toxic
substance,  asbestos  or  related  material  ("Hazardous  Materials")  on  their
properties.  For the  purposes  of this  Agreement,  Hazardous  Materials  shall

other applicable federal, state or local environmental law or regulation. To the
knowledge  of Borrower,  there do not exist upon any property  owned by Borrower
any underground storage tanks or facilities,  and none of such property has ever

material facts or conditions relating to the Loan Papers, any of the Collateral,
or the financial  condition or business of Borrower that could,  collectively or
individually, cause a Material Adverse Change and that have not been related, in
writing,  to  Lender  as an  attachment  to this  Agreement;  and  all  writings
heretofore  or  hereafter  exhibited  or  delivered to Lender by or on behalf of
Borrower  are and will be genuine  and in all  respects  what they  purport  and
appear to be.

7.16 - Closing  Compliance . Borrower  represents to the Lender for all purposes
that as of the  date of the  execution  of this  Agreement,  to the  best of its
knowledge,  it is in full and complete compliance with all applicable regulatory

(c) immediately  upon becoming aware of the existence of, or any material change
in the status of, any litigation which could create a Material Adverse Change if

matter;

(d)  immediately  upon becoming aware of an Event of Default or the existence of
any  condition or event that  constitutes,  or with notice or lapse of time,  or
both,  would  constitute an Event of Default,  a verbal  notification  to Lender
specifying the nature and period of existence  thereof and what action  Borrower
is taking or proposes to take with respect thereto and, immediately  thereafter,
a written confirmation to Lender of such matters;

(e)  immediately  upon becoming  aware that any person has given notice or taken
any other action with respect to a claimed default under any material indenture,
mortgage,  deed of trust,  promissory  note,  loan  agreement,  note  agreement,

matters;

(f) immediately  upon becoming aware of the  commencement of any material action
or material proceeding against Borrower or any of their respective properties by
any governmental  agency,  including,  without limitation,  the Internal Revenue

Federal Energy Regulatory Commission which does or could result in a claim, fine
or judgment  against  Borrower in excess of $100,000.00 if not paid or otherwise
resolved, a written communication to Lender of such matter; and

(g) such other information as may be reasonably requested by Lender.

All financial  statements,  schedules and other financial  information delivered
hereunder  shall be prepared in  conformity  with GAAP and shall be certified as
true and  correct by the  President  or Chief  Financial  Officer of Borrower by
signature and date thereon.

8.2 - Taxes . Borrower will pay and discharge or cause to be paid and discharged
all taxes,  assessments  and  governmental  charges or levies imposed upon it or
upon its  income and  profits or upon any of its  property,  real,  personal  or
mixed,  or upon any part  thereof,  before the same shall become in default,  as
well as all lawful claims for labor, materials and supplies or otherwise, which,
if not  paid,  might  become a Lien upon such  properties  or any part  thereof;
provided that unless any governmental  entity has threatened  seizure or sale of
any Collateral of Borrower for failure to pay any such tax, assessment,  charge,
levy, or claim,  Borrower shall not be required to pay and discharge or cause to
be paid or discharged any such tax, assessment,  charge, levy or claim contested
by it in good  faith by  appropriate  proceedings.  If,  however,  Borrower  has
received  notice of a threatened  seizure or sale of any  Collateral of Borrower
from any governmental  entity, the preceding provision shall be inapplicable and
Borrower shall be required to tender payment under protest to that  governmental
entity before such sale or seizure takes place.

8.3 - Discharge of Contractual  Obligations . Borrower will do and perform every
act and discharge all of the obligations provided to be performed and discharged
under the Loan Papers,  and any and all of the instruments or documents referred
to or mentioned herein at the time or times and in the manner required.

8.4 - Legal  Status .  Borrower  will use its best  efforts to do or cause to be
done all things  necessary to preserve,  renew and keep in full force and effect
its  existences,  rights,  licenses,  permits and franchises and comply with all
laws and regulations applicable to it, and, further,  comply with all applicable
laws and regulations,  whether now in effect or hereafter enacted or promulgated
by any  governmental  authority  having  jurisdiction  over any of its assets or
properties, noncompliance with which would cause a Material Adverse Change.

8.5 -  Maintenance  and  Evidence of  Priority  of Bank Liens .  Borrower  shall
perform such acts and duly authorize, execute,  acknowledge,  deliver, file, and
record  such  additional  assignments,  security  agreements,  deeds  of  trust,
mortgages and other  agreements,  documents,  instruments  and  certificates  as
Lender may  reasonably  deem  necessary or  appropriate  in order to perfect and
maintain  the Bank Liens as a first lien and  preserve and protect the Rights of
Lender  in  respect  of all  present  and  future  Collateral,  and  cause to be
furnished to Lender such opinions of counsel as Lender may request regarding the
priority  of its title to, and the Bank Liens  upon,  its  assets,  all of which
opinions  shall be  prepared by such law firm or firms as may be  acceptable  to
Lender and which  shall be  prepared  in the same  format as those  prepared  in
accordance with Section 8.15 hereinbelow.

8.6 - Insurance . Borrower  presently  maintains  and will  continue to maintain
such policies of liability,  hazard, damage, business interruption and workmen's
compensation  insurance  as  are  customarily  carried  by  companies  similarly
situated.  If requested  by Lender,  any such  policies of insurance  shall show
Lender  therein as loss payee.  Upon  request by Lender,  Borrower  will furnish
Lender with  certificates  and  policies  necessary  to give  Lender  reasonable
assurance of the existence of such coverage.  Borrower agrees to notify promptly
Lender of any  termination  or other  material  change in  Borrower's  insurance
coverage,  and to provide Lender,  upon request,  with all information about the
renewal of each policy at least 15 days prior to the expiration thereof.

8.7 -  Reimbursement  of Fees and  Expenses . Borrower  agrees to pay all legal,
engineering,  and environmental fees and expenses  reasonably incurred by Lender
in connection with the investigation  and negotiation of the financing,  as well
as the preparation and execution of the Loan Papers; provided, however, that all
of such fees, costs, and expenses shall be credited against the Origination Fee.
If such fees and expenses exceed the amount of the Origination Fee, Lender shall
bear  all  such  fees  and  expenses,  not  to  include  those  costs  described
hereinbelow.  Borrower  agrees to pay all costs of filing and recording the Loan
Papers, all legal,  engineering,  and environmental fees and expenses reasonably
incurred by Lender or its  designated  representatives  in  connection  with any
renewal, extension, restatement, supplement or amendment of the Loan Papers, all
costs  associated  with  enforcing any of Lender's  Rights under the Loan Papers
(including,  without limitation, costs of repossessing,  storing,  transporting,
preserving and insuring any of the Collateral),  all court costs associated with
enforcing  or  defending  any  Rights  against   Borrower  or  any  third  party
challenging  said  Rights and any other cost or expense  reasonably  incurred by
Lender or its  designated  representatives  in  connection  herewith or with the
other Loan Papers,  together with interest at the Highest  Lawful Rate per annum
on each such amount commencing 10 days after the date notice of such expenditure
is given to Borrower by Lender until the date it is repaid to Lender.

8.8 - Indemnification . Borrower agrees to indemnify Lender from and against any
and all liabilities,  obligations,  claims, losses, damages, penalties, actions,
judgments,   suits,   remedial   actions,   costs,   expenses  or  disbursements
(collectively,  "Claims") of any kind or nature  whatsoever  that may be imposed
on, incurred by, or asserted against Lender by any third party growing out of or
resulting from (i) a breach of the Loan Papers and the  transactions  and events
at any time associated therewith (including, without limitation, the enforcement
of the Loan  Papers  and the  defense  of  Lender's  actions  and  inactions  in
connection  with the  Loan),  except  to the  limited  extent  such  Claims  are
proximately caused by Lender's gross negligence or willful misconduct;  (ii) the
presence of any Hazardous  Materials on or under properties  covered by the Deed
of  Trust;  or  (iii)  any  activity  carried  on or  undertaken  on or off  the
properties  covered  by the Deed of Trust,  whether  prior to or during the term
hereof and whether by  Borrower  or any third  person,  in  connection  with the
treatment,  storage,  recycling,  removal,  handling or  disposal  of  Hazardous
Materials at any time located on or under the properties  covered by the Deed of
Trust.

8.9 - Indemnification Procedure. In the event that Lender discovers or otherwise
becomes  aware of an  indemnification  claim  arising  under Section 8.8 of this
Agreement, Lender shall give written notice to Borrower,  specifying such claim,
and may  thereafter  exercise  any  remedies  available  to  Lender  under  this
Agreement;  provided,  however,  that the  failure  of Lender to give  notice as
provided herein shall not relieve Borrower of any obligations hereunder,  to the
extent Borrower is not materially  prejudiced thereby.  Further,  promptly after
receipt  by  Lender  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 8.8,  Lender shall,  if a claim in respect  thereof is to be
made against  Borrower,  give written notice to Borrower of the  commencement of
such  action;  provided  however,  that the  failure of Lender to give notice as
provided herein shall not relieve Borrower of any obligations hereunder,  to the
extent Borrower is not materially prejudiced thereby. In case any such action is
brought  against  Lender,  Borrower  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 Lender, and after notice from Borrower to Lender of its election so to assume
the  defense  thereof,  Borrower  shall not be liable to Lender for any legal or
other  expenses  subsequently  incurred  by the  latter in  connection  with the
defense  thereof unless  Borrower has failed to assume the defense of such claim
and to employ counsel reasonably  satisfactory to Lender. If Borrower elects not
to assume the defenses of a claim, Borrower shall not be liable for the fees and
expenses of more than one  counsel in any single  jurisdiction  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, Lender will be entitled to select its own counsel
and assume defense of any action brought  against it if Borrower fails to select
counsel  reasonably  satisfactory to Lender,  the expenses of such defense to be
paid by Borrower.  Borrower  shall not consent to entry of any judgment or enter
into any settlement with respect to a claim without the consent of Lender, which
consent  shall  not  be  unreasonably  withheld,  or  unless  such  judgment  or
settlement  includes as an unconditional term thereof a release of Lender by the
claimant or plaintiff  from all  liability  with  respect to such claim.  Lender
shall not consent to entry of any judgment or enter into any  settlement  of any
such  action,  the defense of which has been  assumed by  Borrower,  without the
consent of Borrower,  which consent shall not be unreasonably  withheld.  In the
event that Lender becomes entitled to compensation from Borrower pursuant to the
provisions  of Section 8.8, any such  compensation  shall bear  interest at that
Highest  Lawful Rate per annum from the date of  Lender's  payment of any claims
until paid by Borrower and shall be part of the  Obligation  secured by the Bank
Liens.

8.10 - Curing of  Defects .  Borrower  will  promptly  cure any  defects  in the
execution and delivery of any of the Loan Papers, and in any other instrument or
document referred to or mentioned herein.  Borrower will immediately execute and
deliver to Lender upon request, all such other and further instruments as may be
reasonably required or desired by Lender from time to time in compliance with or
accomplishment  of the  covenants  and  agreements  of Borrower made in the Loan
Papers.

8.11 - Inspection  and  Visitation . Borrower will grant Lender access to all of
its books and records, as well as to all of the Collateral, and allow inspection
and  copying  of same by Lender or its  designated  representatives  at any time
during  normal  business  hours or such  other  time as  Lender  may  reasonably
request;  provided,  however,  that nothing in this  Section 8.11 shall  require
Borrower to provide access to Lender to any books,  records,  or other materials
covered by a confidentiality  agreement that has been entered into as the result
of arms-length negotiations between Borrower and an unrelated third party.

8.12 -  Notices .  Borrower  will give  prompt  written  notice to Lender of any
proceedings  instituted against it by or in any federal or state court or before
any commission or other  regulatory  body,  federal,  state or local,  which, if
adversely determined, would cause a Material Adverse Change.

8.13 - Compliance . Borrower will observe and comply with:

(a) All laws, statutes, codes, acts, ordinances, rules, regulations,  directions
and requirements of all federal, state, county, municipal and other governments,
departments,  commissions, boards, courts, authorities,  officials and officers,
domestic and foreign,  including  but not limited to all  applicable  regulatory
requirements promulgated by any governmental agency including OSHA, the EPA, the
Pension  Benefit  Guaranty  Fund,  ERISA,  and any other  applicable  regulatory
agency,  where the failure to observe or comply  would cause a Material  Adverse
Change;

(b) all  orders,  judgments,  decrees,  injunctions,  certificates,  franchises,
permits,  licenses, and authorizations of all federal, state, county, municipal,
and other governments,  departments,  commissions,  boards, courts, authorities,
officials,  and officers,  domestic and foreign, which the failure to observe or
comply would cause a Material Adverse Change and against which it shall maintain
such reserves as are appropriate under GAAP; and

(c) GAAP in all of its accounting procedures.

8.14 -  Compliance  With  Environmental  Laws .  Borrower,  to the  best  of its
knowledge, is in substantial compliance with all state and federal environmental
laws and  regulations  and will remain in substantial  compliance  with same and
will not  place or permit to be placed  any  Hazardous  Materials  on any of its
properties in violation of applicable state and federal  environmental  laws. In
the event  Borrower  should  discover  any  Hazardous  Materials on any of their
properties  which could result in a breach of the foregoing  covenant,  Borrower
shall notify Lender within three (3) days after such  discovery.  Borrower shall
dispose of all material amounts of Hazardous  Materials  generated by it only at
facilities and/or with carriers that Borrower reasonably believes maintain valid
governmental permits under the Resource Conservation and Recovery Act, 42 U.S.C.
ss.6901.  In the event of any notice or filing of any procedure against Borrower
alleging a violation of any environmental law or regulation, Borrower shall give
notice to Lender within five (5) days after  receiving  notice of such notice or
filing.

8.15 -  Post-Closing  Title  Review.  Within sixty (60) days of the execution of
this Agreement,  Lender shall obtain title reports covering Mortgaged Properties
that represent  eighty percent (80%) or more of the net proven value of Lender's
most recent  engineering  evaluation.  Such title  reports  shall be prepared by
legal  counsel  of  Lender's  choice.  The cost of such title  reports  shall be
included in the Origination Fee. To the extent possible,  the title reports will
be based upon prior title opinions  obtained from  Borrower's  files and reports
prepared by landmen  selected by Lender  during the course of its due  diligence
review.  Within  thirty  (30) days of  Lender's  receipt of such title  reports,
Borrower  shall  cure any title  defects  reported  therein  for which  curative
activity is reasonably required by Lender, acting in its sole discretion.

                                   ARTICLE IX

(a) The  acceptance  by Lender at any time and from time to time of part payment
on the  Obligation  shall not  operate as a waiver of any Event of Default  then
existing.

(b) No waiver by Lender of any Event of Default shall operate as a waiver of any
other then existing or subsequent Event of Default.

(c) No delay or omission  by Lender in  exercising  any Right shall  impair such
Right or operate as a waiver thereof,  nor shall any single or partial  exercise

obligation, if any, to make further Advances.

11.4 - Strict  Compliance . If any action or failure to act by Borrower violates
any covenant of Borrower  contained herein or in any other Loan Paper, then such
violation  shall not be excused  by the fact that such  action or failure to act
would  otherwise be required or  permitted by any covenant (or  exception to any
covenant) other than the covenant violated.

11.5 -  Cumulative  Rights . The Rights of Lender  under the Loan  Papers are in
addition to all other Rights  provided by law,  whether or not the Obligation is
due and payable and whether or not Lender has instituted any suit for collection
or other action in connection with the Loan Papers.

11.6 - Governing Laws . This Agreement has been prepared,  is being executed and
delivered,  and  is  intended  to be  performed,  in the  State  of  Texas.  The
substantive  laws of such state and the  applicable  federal  laws of the United

that the  rights  provided  in the Loan  Papers  with  reference  to  properties
situated in other states may be governed by the laws of such other states.

suit, action or proceeding against Borrower arising out of or relating to any of
the Loan Papers or any judgment entered by any court in respect thereof,  may be

in the United States District Court for the Western District of Texas, as Lender
in  its  sole  discretion  may  elect,   and  Borrower  hereby  submits  to  the
nonexclusive  jurisdiction  of such  courts  for the  purpose  of any such suit,
action or proceeding. Borrower hereby irrevocably consents to service of process
in any suit,  action or proceeding in any of said courts by the mailing  thereof
by Lender by registered or certified mail, postage prepaid, to Borrower,  at its
address as set forth herein.  Borrower hereby  irrevocable waives any objections
that they may now or hereafter  have to the laying of venue of any suit,  action
or proceeding arising out of or relating to any of the other Loan Papers brought
in any said courts and hereby further  irrevocably waive any claim that any such
suit,  action or  proceeding  brought in any such  court has been  brought in an
inconvenient forum and any right granted by statute,  rule or court or otherwise
to have such suit, action or proceeding tried by a jury.

11.8 - Enforceability  . If one or more of the provisions  contained in the Loan
Papers shall, for any reason, be held to be invalid, illegal or unenforceable in
any respect, such validity, illegality, or unenforceability shall not affect any
other provision of the Loan Papers or any other instrument referred to herein.

11.9 - Binding  Effect . The Loan Papers  shall be binding upon and inure to the
benefit of Borrower  and Lender and their  respective  successors  and  assigns;
provided,   however,  that  Borrower  may  not  assign  any  Rights,  duties  or
obligations under the Loan Papers without the prior written consent of Lender.

liable to any third  party,  including,  without  limitation,  any  materialman,
supplier, contractor, subcontractor,  purchaser, lessor or lessee having a claim
against Borrower.  Notwithstanding anything contained in the Loan Papers, or any
conduct or course of conduct by any or all of the parties hereto, whether before
or after signing this Agreement or any other Loan Paper,  no Loan Paper shall be
construed  as creating  any right,  claim or cause of action  against  Lender in
favor of any  third  party,  including,  without  limitation,  any  materialman,
supplier, contractor, subcontractor,  purchaser, lessor or lessee having a claim
against Borrower.

(b) All  conditions to the  obligation of Lender to make Advances  hereunder are
imposed solely and  exclusively  for the benefit of Lender,  and no other person
shall have  standing to require  satisfaction  of such  conditions in accordance
with their  terms or be  entitled  to assume  that Lender will make or refuse to
make Advances in the absence of strict compliance  therewith,  and any or all of
such  conditions  may be freely waived in whole or in part by Lender at any time
if Lender, in its sole and absolute discretion, deems it advisable to do so.

any of its Rights by or through its officers, directors,  employees,  attorneys,
agents or other representatives.

11.12 - Setoff . Borrower  hereby grants to Lender (and to each  participant  to
whom Lender has conveyed or may hereafter  convey a  participation  in the Note)
the right of setoff (which right shall not be exercised  prior to the occurrence
of an Event of Default)  to secure  payment of the  obligation  upon any and all
moneys, securities or other property of Borrower and the proceeds therefrom, now
or  hereafter  held  or  received  by or in  transit  to,  Lender  or  any  such
participant or any agent of Lender or such participant,  from or for the account
of Borrower, whether for safekeeping, custody, pledge, transmission,  collection
or  otherwise,  and also upon any and all  deposits  (general or  specific)  and
credits of  Borrower  and any and all claims of Borrower  against  Lender or any
such participant at any time existing.

11.13 -  Additional  Documents  . It is  contemplated  that there may be certain
supplementary and/or corrective  mortgages,  deeds of trust, security agreements
and similar  items  prepared  by Lender to be  executed  by Borrower  subsequent
hereto,  as well as certain other  corrective and additional  documentation  not
executed  concurrently  with this  Agreement  because of the  unavailability  of
information  such as property  and  collateral  descriptions  at the time of the
execution  hereof.  Borrower  agrees to  cooperate  with Lender and provide such
information  in connection  therewith as Lender may reasonably  request,  and to
execute  and  deliver  such  other and  further  documentation  as Lender  shall
reasonably  request so as to provide Lender with a Bank Lien on the  Collateral.
Further,  upon Lender's  reasonable  request,  Borrower shall provide such title

South LaSalle Street, Chicago,  Illinois 60603 or such other place as the holder
hereof may from time to time designate in writing, in legal tender of the United
States of America, the principal sum of Sixteen Million One Hundred Eighty-Seven
Thousand Dollars  ($16,187,000) or so much thereof as may be borrowed  hereunder
and  reflected  on Schedule "A"  attached  hereto and made a part  hereof,  plus
interest from the date hereof on the unpaid principal balance as follows:

The  principal  amount  available to be borrowed  under this Note (the  "Maximum
Amount")  shall be repaid in monthly  installments  of  $192,703.00  each on the
first  day of  each  month  beginning  May 1,  1997,  and at no time  shall  the
outstanding  principal  exceed the  Maximum  Amount.  The  principal  sum hereof
outstanding  shall be due and payable on the end of the "Term" as defined in the
Loan Agreement described herein.

Interest  shall be earned at the rate (the "Annual  Rate") of one-quarter of one
percent  (.25%)  per annum plus the "Prime  Rate".  The "Prime  Rate" is the per
annum rate of interest publicly announced by Chase Manhattan Bank, New York, New
York, or the applicable rate of its successors or assigns,  from time to time as
its prime rate (the prime rate is not intended to be the lowest rate of interest
charged by Chase  Manhattan  Bank,  New York,  New York,  or its  successors  or
assigns, to its borrowers). Such interest shall be payable monthly in arrears on
the first day of each and every month,  commencing on the first day of the month
after an advance is made  hereunder.  Interest  shall be  computed on the unpaid
principal  balance and shall be calculated on a year of 360 days for actual days
elapsed.  Interest and principal not paid when due shall bear interest at a rate
equal to two percent (2%) per annum in excess of the Annual Rate." The remaining
provisions of the Yale Note are unchanged.
