                   Notes to Consolidated Financial Statements
                                December 31, 1997
                                   (Unaudited)

1.  SUMMARY  OF  SIGNIFICANT  ACCOUNTING  POLICIES  The  unaudited  consolidated
financial  statements of Key Energy Group, Inc. (the "Company" or "Key") and its
wholly-owned  subsidiaries  are prepared in conformity  with generally  accepted
accounting  principals,  but do not purport to be a complete  presentation in as
much  as all  note  disclosures  required  are  not  included.  These  unaudited
consolidated financial statements should be read in conjunction with the audited
consolidated  financial  statements of the Company and notes thereto included in
the Company's Annual Report on Form 10-K for the year ended June 30, 1997.

In the opinion of management,  the Company's  unaudited  consolidated  financial
statements as of December 31, 1997 and for the three months and six months ended
December 31, 1997 and 1996 contain all adjustments and accruals, consisting only
of normal recurring  accrual  adjustments,  necessary for a fair presentation of
the results of the interim  periods.  These interim  results are not necessarily
indicative of results for a full year.

Earnings per Share

The Company implemented the Statement of Financial  Accounting Standards No. 128
("SFAS 128") - Earnings per Share, for the quarter ended December 31, 1997. SFAS
128 replaces the  presentation  of primary  earnings per share  ("EPS") with the
presentation  of basic EPS, which excludes  dilution and is computed by dividing
income available to common shareholders by the weighted-average number of common
shares outstanding for the period. SFAS 128 has been applied  retro-actively for
each period  presented.  In accordance with SFAS 128, the  reconciliation of the
numerators and denominators of basic EPS and diluted EPS is presented below:

3.  LONG-TERM DEBT

At December 31, 1997, major  components of the Company's  long-term debt were as
follows:

PNC Credit Agreement

On June 6, 1997,  the Company  entered into an agreement,  (the "Initial  Credit
Agreement")  with  PNC  Bank,  N.A.  ("PNC"),  as  administrative  agent,  and a
syndication  of other  lenders  pursuant  to which the  lenders  provided a $255
million credit facility, consisting of a $120 million seven-year term loan and a
$135 million  five-year  revolver.  The interest rate on the term loan was LIBOR
plus 2.75 percent.  The interest rate on the revolver  varied based on the LIBOR
and the  level of the  Company's  indebtedness.  The  Initial  Credit  Agreement
contained  certain  restrictive  covenants  and required the Company to maintain
certain  financial  ratios.  On September 25, 1997,  the Company repaid the term
loan and a portion of the then outstanding  amounts under the revolver  applying
the  proceeds  from the initial and second  closings  of the  Company's  private
placement  of $216  million  of 5%  Convertible  Subordinated  Notes  (discussed
below).

Effective  November 6, 1997,  the Company  entered  into an Amended and Restated
Credit Agreement with PNC (the "Amended Credit  Agreement"),  as  administrative
agent and lender, pursuant to which PNC agreed to make revolving credit loans of
up to a  maximum  loan  commitment  of  $200  million.  The  maximum  commitment
decreases to $175 million on November 6, 2000 and to $125 million on November 6,
2001. The loan commitment  terminates on November 6, 2002.  Borrowings under the
credit  facility  may be either  (i)  Eurodollar  Loans  with  interest  payable
quarterly at LIBOR plus 1.25% subject to adjustment  based on certain  financial
ratios,  (ii) Base Rate Loans with interest payable  quarterly at the greater of
PNC  Prime  Rate or the  Federal  Funds  Effective  Rate  plus 1/2 %,or  (iii) a
combination  thereof,  at the Company's  option.  The Amended  Credit  Agreement
contains  certain  restrictive  covenants  and  requires the Company to maintain
certain financial ratios. A change of control of the Company,  as defined in the
Amended Credit Agreement,  is an event of default.  Borrowings under the Amended
Credit Agreement are secured by  substantially  all of the assets of the Company
and its domestic subsidiaries.

Effective  December 3, 1997, PNC completed the syndication of the Amended Credit
Agreement  and,  in  connection  therewith,  PNC,  as  administrative  agent,  a
syndication  of lenders and the Company  entered  into a First  Amendment to the
Amended and Restated  Credit  Agreement  providing for,  among other things,  an
increase in the maximum commitment from $200 million to $250 million.

At December 31, 1997, the principal balance of the Amended Credit Agreement,  as
amended,   was  $107  million  and  the  unused   credit   facility   aggregated
approximately $143 million,  with approximately $3 million reserved for existing
letters of credit.

7% Convertible Subordinated Debentures

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

                                     - 11 -


<PAGE>


Subordinated Debentures due 2003 (the "Debentures"), pursuant to Rule 144A under
the Securities Act of 1933, as amended (the "Securities  Act").  The Debentures
are subordinate to the Company's  senior  indebtedness,  which as defined in the
indenture pursuant to which the Debentures were issued,  includes the borrowings
under the Amended Credit  Agreement,  as amended.  Interest on the Debentures is
payable on January 1 and July 1 of each year.

The Debentures are convertible,  at any time prior to maturity,  at the holders'
option,  into shares of Common Stock at a  conversion  price of $9.75 per share,
subject to certain adjustments. In addition, Debenture holders who convert prior
to July 1, 1999 will be entitled to receive a payment,  in cash or Common  Stock
(at the  Company's  option),  generally  equal to 50% of the interest  otherwise
payable from the date of conversion through July 1, 1999.

The Debentures are  redeemable,  at the option of the Company,  on or after July
15,  1999,  at a  redemption  price  of  104%,  decreasing  1% per  year on each
anniversary date thereafter.

In the event of a change in control of the Company,  as defined in the indenture
under which the Debentures were issued,  each holder of Debentures will have the
right, at the holder's  option,  to require the Company to repurchase all or any
part of the holder's Debentures within 60 days of such event at a price equal to
100% of the principal amount thereof,  together with accrued and unpaid interest
thereon.
 
As of December 31, 1997,  $47,400,000 in principal  amount of the Debentures had
been  converted  into  5,062,369  shares  of Common  Stock at the  option of the
holders.  The number of shares issued  included  200,831 shares in excess of the
number of shares  issuable  at the  conversion  price of $9.75 per share.  These
additional  shares were issued by the Company to induce  conversion.  Such
additional  consideration  was  accounted  for as an increase  to the  Company's
equity. In addition,  the proportional  amount of debt issuance costs associated
with the converted  Debentures  was accounted for as a decrease to the Company's
equity.

At December 31, 1997, $4,600,000 of Debentures remained outstanding.

5% Subordinated Notes

On September 25, 1997, the Company  completed an initial  closing of its private
placement of $200  million of 5%  Convertible  Subordinated  Notes due 2004 (the
"Notes").  On October 7, 1997,  the Company  completed  a second  closing of its
private placement of an additional $16 million of Notes pursuant to the exercise
of the remaining  portion of the  over-allotment  option  granted to the initial
purchasers of Notes. The placements were made as private  offerings  pursuant to
Rule 144A and Regulation S under the Securities  Act. The Notes are  subordinate
to the Company's senior  indebtedness,  which, as defined in the indenture under
which the Notes were issued,  includes the  borrowings  under the Amended Credit
Agreement,  as  amended.  Interest  on the  Notes  is  payable  on  March 15 and
September 15, commencing March 15, 1998.

The Notes are convertible,  at the holder's option,  into shares of Common Stock
at a conversion price of $38.50 per share, subject to certain adjustments.

The Notes are  redeemable,  at the Company's  option,  on or after September 15,
2000, in whole or part,  together with accrued and unpaid interest.  The initial
redemption  price is  102.86%  for the year  beginning  September  15,  2000 and
declines ratably thereafter on an annual basis.

In the event of a change in control of the Company,  as defined in the indenture
under which the Notes were issued,  each holder of Notes will have the right, at
the holde's option, to require the Company to repurchase all or any part of the
holder's  Notes,  within 60 days of such event,  at a price equal to 100% of the
principal amount thereof, together with accrued and unpaid interest thereon.

Proceeds from the placement of the Notes were used to repay  balances  under the
Company's  credit  facilities  (see above).  At December 31, 1997,  $216,000,000
principal amount of the Notes was outstanding.

4.  RECENTLY ISSUED ACCOUNTING STANDARDS

individuals.  The 1997 Incentive  Plan  authorizes the granting of stock options
and other  stock-based  incentive awards covering an aggregate of the greater of
(i)  3,000,000  shares  of Common  Stock or (ii) 10% of the  number of shares of
Common Stock issued and  outstanding  on the last day of each calendar  quarter,
provided,  however,  that a decrease  in the  number of issued  and  outstanding
shares of Common Stock from the previous calendar quarter; shall not result in a
decrease in the Common Stock  available for issuance  under the  Company's  1997
Incentive Plan. Presently, 3,000,000 shares of Common Stock are authorized under
the 1997 Incentive Plan.  Options  previously granted under the Prior Plans were
assumed and continued by the 1997 Incentive Plan.

As of January 13, 1998, options to purchase 2,306,224 shares of Common Stock are
outstanding under the 1997 Incentive Plan.

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

The following  discussion and analysis  should be read in  conjunction  with the
audited consolidated  financial statements and the notes thereto included in the
Company's Annual Report on Form 10-K for the year ended June 30, 1997.

Current and Subsequent Events

During the six months  ended  December  31,  1997,  the  Company  purchased  the
remaining 37% minority  interest in Servicios and completed the  acquisition  of
the following well servicing, trucking and drilling companies:

                  Patrick Well Service, Inc.
                  Kenting Holdings (Argentina) S.A.
                  Mosley Well Service, Inc.
                  Ram Oil Well Service, Inc. and Rowland Trucking Co. Inc.
                  Waco Oil & Gas Co., Inc.
                  Landmark Fishing & Rental, Inc.
                  BRW Drilling, Inc.
                  Dunbar Well Service, Inc.
                  Frontier Well Service, Inc.
                  Big A Well Service Co., Sunco Trucking Co. and 
                   Justice Supply Co., Inc.
                  GSI Trucking Company, Inc., Kahlden Production 
                   Services, Inc. and McCurdy Well Service, Inc.
                  Jeter Service Co.
                  Win-Tex Drilling Co., Inc. and Win-Tex Trucking Corporation
                  Wellcorps, L.L.C., White Rhino Drilling, Inc. and
                   S&R Cable, Inc.

These acquisitions (which are more fully described in Note 2 to the consolidated
financial  statements) involve 192 well service rigs (including six well service
rigs in  Argentina),  210 fluid  hauling and other  trucks and 28 drilling  rigs
(including three drilling rigs in Argentina).  The total purchase price of these
acquisitions  totaled  approximately $152 million,  compromised of approximately
$142 million in cash and 365,000 shares of Common Stock.

Subsequent to December 31, 1997 and through  February 13, 1998,  the Company has
completed the  acquisition of four well  servicing  companies and three contract
drilling companies involving 99 well service rigs, 21 drilling rigs and 24 fluid
hauling  and  other  trucks.  The  total  purchase  price  of  these  subsequent
acquisitions aggregate approximately $63.4 million, compromised of approximately
$60 million in cash and 200,000 shares of Common Stock.

These  acquisitions  were financed  primarily  through long-term debt borrowings
(see Note 3 to the consolidated  financial  statements) and, to a lesser extent,
through internally generated funds.

Including these recent  acquisitions,  as of February 13, 1998, the Company owns
820 oilfield  servicing rigs, 628 oilfield fluid hauling and other trucks and 59
land drilling  rigs.  Management  believes  that,  as of February 13, 1998,  the
Company's  active well  servicing and fluid hauling fleet is the largest  active
onshore fleet in the continental  United States and is the second largest active
fleet in  Argentina.  The  Company  operates  in most major  onshore oil and gas
producing  regions of the  continental  United  States,  with the  exception  of
California,  and  provides a full range of  drilling,  completion,  maintenance,
workover and plugging and abandonment services for the oil and gas industry.

                                     - 15 -

Impact of Declining Crude Oil Prices

During the quarter  ended  December  31,  1997,  the posted  price of West Texas
intermediate  crude oil (the"West Texas  Crude Oil Price")  fell from prices in
excess of $20 per barrel to prices of less than $17 per  barrel.  From  December
31, 1997 through  February 13, 1998,  the West Texas Crude Oil Price remained in
the range of $15.50 to $17.50 per barrel.  This  decline in prices is thought to
be caused primarily by an oversupply of crude oil inventory created, in part, by
an unusually warm winter in the United States and Europe, an announced  increase
in crude oil  production  quotas for OPEC  countries  and a possible  decline in
demand in certain Asian markets.

If such a decline in the West Texas Crude Oil Price  worsens or  persists  for a
protracted period, the Company's oilfield service and drilling  operations would
likely be  affected  by  postponements  of  drilling  commitments  and delays in
scheduled  maintenance  service for marginally  producing  wells which, in turn,
could adversely effect the Company's service and drilling rig utilization rates,
pricing structures, revenues, net income and cash flows from operations.

Growth Strategy

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

Over the past eighteen months, the Company has been the leading  consolidator of
this  industry,  completing  35  acquisitions  of well  servicing  and  drilling
operations  through December 31, 1997 and 42 such acquisitions  through February
13, 1998. This consolidation has led to reduced  fragmentation in the market and
a more predictable demand for well services for the Company and its competitors.
The  Company's  management  structure is  decentralized,  which allows for rapid
integration of acquisitions and the retention of strong local identities of many
of the acquired businesses.

As a result of these and other  factors,  the  Company  has  developed  a growth
strategy to:
               1. Identify,  negotiate and consummate additional acquisitions of
          complementary well servicing operations,  including rigs, trucking and
          other ancillary services;
                
               2. Fully integrate acquisitions into the Company's  decentralized
          organizational  structure  and thereby  attempt to maximize  operating
          margins;

               3. Expand  business lines and services  offered by the Company in
          existing areas of operations; and,

               4. Extend the geographic scope and operating environments for the
          Company's operations.

<PAGE>

If the current decline in the West Texas Crude Oil Price worsens or persists for
a protracted  period,  the Company may curtail or halt its growth strategy until
such time as prices reach more favorable ranges.

RESULTS OF OPERATIONS

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  consolidated  financial  statements and related notes
thereto appearing elsewhere in this report.

QUARTER ENDED DECEMBER 31, 1997 VERSUS THE QUARTER ENDED DECEMBER 31, 1996

Net Income

For the quarter  ended  December  31, 1997,  the Company  reported net income of
$7,345,000  ($.40 per share - basic) as compared to $2,043,000 ($.19 per share -
basic) for the quarter  ended  December  31, 1996,  representing  an increase of
$5,302,000, or 260%. The increase in net income is primarily attributable to the
Company's  acquisitions completed between October 1, 1996 and December 31, 1997,
increased service and drilling rig utilization rates and price increases.

Revenues

The Company's  total  revenues for the quarter ended December 31, 1997 increased
by $73,476,000,  or 203%, to $109,673,000  compared to $36,197,000  reported for
the quarter ended December 31, 1996. The increase is primarily  attributable  to
the Company's  acquisitions of oilfield  service and drilling rig companies (see
Note 2 to the consolidated financial statements),  increased demand for oilfield
service equipment and recent price increases for oilfield services. From October
1, 1996  through  December 31,  1997,  the Company has added 387 well  servicing
rigs, 413 fluid hauling trucks and 31 drilling rigs to its fleet.

Oilfield service revenues for the current quarter  increased by $65,834,000,  or
208%,  to  $97,542,000  compared to  $31,708,000  reported for the quarter ended
December  31,  1996.   The   increase  is  primarily   attributable   to  recent
acquisitions,  increased demand for oilfield service  equipment and recent price
increases for oilfield services.

Drilling  revenues  for  the  quarter  ended  December  31,  1997  increased  by
$6,330,000,  or 268%,  to  $8,689,000  compared to  $2,359,000  reported for the
quarter  ended  December 31, 1996.  The  increase is primarily  attributable  to
recent drilling rig acquisitions, higher rig utilization and price increases.

Oil and gas  revenues  for the quarter  ended  December  31, 1997  decreased  by
$139,000,  or 7%, to $1,949,000  compared to $2,088,000 reported for the quarter
ended December 31, 1996. The decrease is primarily  attributable  to lower crude
oil and natural gas prices.

Costs and Expenses and Operating Margins

The Company's  total costs and expenses for the quarter ended  December 31, 1997
increased  by  $64,651,000,  or 195%,  to  $97,826,000  compared to  $33,175,000
reported  for the quarter  ended  December  31,  1996.  The increase is directly
attributable  to  increased  operating  costs and expenses  associated  with the
Company's recent acquisitions.

Oilfield  service  expenses for the quarter ended December 31, 1997 increased by
$45,288,000,  or 196%, to $68,354,000  compared to $23,066,000  reported for the
quarter ended December 31, 1996.  Oilfield service margins (revenues less direct
costs and  expenses)  increased  for the  quarter  ended  December  31,  1997 by
$20,546,000,  or 238%, to $29,188  compared to $8,642,000  for the quarter ended
December 31, 1996.  Oilfield service margins as a percentage of oilfield service
revenue  for the  quarters  ended  December  31,  1997 and 1996 was 30% and 27%,
respectively. Such increases are due primarily to acquisitions, increased demand
for oilfield services and increased  operating  efficiencies.  In addition,  the
Company has continued to expand its services,  offering higher margin  ancillary
services and equipment such as well fishing tools,  blow-out preventers and frac
tanks.

<PAGE>


The  Company's  contract  drilling  costs and  expenses  for the  quarter  ended
December 31, 1997  increased by $4,627,000,  or 236%, to $6,590,000  compared to
$1,963,000 for the quarter ended December 31, 1996.  Oilfield  drilling  margins
for the Company's drilling operations during the quarter ended December 31, 1997
increased by  $1,703,000,  or 430%, to  $2,099,000  compared to $396,000 for the
quarter ended  December 31, 1996.  Oilfield  drilling  margin as a percentage of
oilfield  drilling revenue for the quarters ended December 31, 1997 and 1996 was
24% and 17%,  respectively.  Such  increases are  attributable  to the Company's
recent   acquisition   of  drilling  rig  companies   and  increased   operating
efficiencies.

There was no significant change in oil and gas production costs and expenses for
the quarter ended December 31, 1997.

General and  administrative  expenses  for the quarter  ended  December 31, 1997
increased by $6,635,000,  or 180%, to $10,370,000 compared to $3,735,000 for the
quarter ended December 31, 1996. The increase was primarily  attributable to the
Company's recent acquisitions and expanded services.  General and administrative
expenses  as a  percentage  of total  revenue  decreased  from 10.3%  during the
quarter ended December 31, 1996 to 9.5% for the quarter ended December 31, 1997.

Depreciation,  depletion and amortization expense for the quarter ended December
31, 1997 increased by $5,398,000,  or 230%, to $7,740,000 compared to $2,342,000
for the quarter ended December 31, 1996. The increase is directly related to the
increase in property and equipment and long-term  debt issuance cost incurred by
the Company over the past eighteen months in conjunction with its acquisitions.

Interest   expense  for  the  quarter  ended  December  31,  1997  increased  by
$2,583,000,  or 199%, to $3,879,000 compared to $1,296,000 for the quarter ended
December  31,  1996.   The  increase  was  primarily  the  result  of  increased
indebtedness as a result of the Company's acquisition program.

Income tax  expense  for the  quarter  ended  December  31,  1997  increased  by
$3,473,000,  or 338%, to $4,502,000 compared to $1,029,000 for the quarter ended
December 31, 1996. The Company does not expect to have to pay the full amount of
the  income  tax  provision  because  of the  availability  of  accelerated  tax
depreciation, drilling tax credits, and tax loss carry-forwards.

Cash Flows

Net cash provided by operating  activities  for the quarter  ended  December 31,
1997 increased by $8,450,000, to $7,361,000 compared to the  $1,089,000  used by
operating  activities  for the quarter ended  December 31, 1996. The increase is
primarily   attributable  the  acquisitions,   increased  service  and  drilling
operating margins,  increased service and drilling utilization rates,  increased
operating  efficiencies  and, to a lesser extent,  increased prices for oilfield
service and drilling.

Net cash used in investing  activities  for the quarter ended  December 31, 1997
increased by $35,778,000,  or 204%, to $53,298,000  compared to $17,520,000 used
for the quarter ended December 31, 1996.  This increase is primarily  related to
the Company's recent acquisitions.

Net cash provided by financing  activities  for the quarter  ended  December 31,
1997 increased by $39,717,000,  or 371%, to $50,431,000  compared to $10,714,000
provided  during the quarter ended  December 31, 1996. The increase is primarily
the  result of the  proceeds  from  long-term  debt (see Note 3 to  consolidated
financial statements) and partially offset by the repayment of such debt.

SIX MONTHS ENDED DECEMBER 31, 1997 VERSUS THE SIX MONTHS ENDED DECEMBER 31, 1996

Net Income

For the six months ended December 31, 1997,  the Company  reported net income of
$12,283,000 ($.76 per share - basic) as compared to $3,597,000 ($.34 per share -
basic) for the six months ended December 31, 1996, an increase of $8,686,000, or
241%.  The increase in net income is  primarily  attributable  to the  Company's
acquisitions  completed between October 1, 1996 and December 31, 1997, increased
service and drilling rig utilization rates,  increased operational  efficiencies
and price increases.

Revenues

The  Company's  total  revenues  for the six  months  ended  December  31,  1997
increased by $117,534,  or 174%, to $185,193,000 compared to $67,659,000 for the
six months  ended  December  31,  1996.  The  increase  is  attributable  to the
Company's  recent  acquisitions of oilfield  service and drilling rig companies,
increased utilization and higher prices for oilfield services.

Oilfield  service  revenues for the six months ended December 31, 1997 increased
by $108,021,000,  or 183%, to $167,040,000  compared to $59,019,000 reported for
the six months ended December 31, 1996.  The increase is primarily  attributable
to recent  acquisitions,  higher demand for oilfield service equipment and, to a
lesser extent, from recent price increases for oilfield services.

Drilling  revenues  for the six months  ended  December  31, 1997  increased  by
$6,829,000,  or 146%, to $11,512,000 compared to $4,683,000 reported for the six
months ended December 31, 1996. The revenue  increase is primarily  attributable
to recent drilling rig acquisitions, higher rig utilization and price increases.

Oil and gas  revenues for the six months  ended  December 31, 1997  increased by
$454,000,  or 13%, to $4,067,000 compared to $3,613,000 for the six months ended
December 31, 1996.  The increase is directly  attributable  to increased oil and
gas  production as a result of the Company's  oil and gas  acquisitions  for the
fiscal year ended June 30, 1997 and was partially  offset by lower crude oil and
natural gas prices during the last three months of calendar 1997.

Costs and Expenses and Operating Margins
 
The  Company's  total costs and expenses  for the six months ended  December 31,
1997 increased by $103,274,000, or 166%, to $165,515,000 compared to $62,241,000
reported  for the six months ended  December 31, 1996.  The increase is directly
attributable  to  increased  operating  costs and expenses  associated  with the
Company's recent acquisitions.

Oilfield  service  expenses for the six months ended December 31, 1997 increased
by $73,826,000,  or 173%, to $116,592,000  compared to $42,766,000  reported for
the six months ended December 31, 1996.  Oilfield service margins (revenues less
direct costs and expenses) for the six months ended  December 31, 1997 increased
$34,195,000,  or 210%, to $50,448,  compared to  $16,253,000  for the six months
ended December 31, 1996.  Oilfield  service  margins as a percentage of oilfield
service revenues for the six months ended December 31, 1997 and 1996 was 30% and
28%,  respectively.  The increases in oilfield services expenses and margins are
due  primarily to  acquisitions,  increased  demand for oilfield  services,  the
Company's  expansion of its ancillary  oilfield services and equipment,  such as
well  fishing  tools,  blowout  preventers  and well frac tanks,  and  increased
operating efficiencies.

Drilling costs and expenses for the six months ended December 31, 1997 increased
by $5,009,000,  or 130%, to $8,853,000 compared to $3,844,000 for the six months
ended December 31, 1996.  Drilling  margins during the six months ended December
31, 1997  increased by $1,820,000,  or 217%, to $2,659,000  compared to $839,000
for the six months  ended  December  31,  1996.  Oilfield  drilling  margin as a
percentage of oilfield  drilling  revenue for the six months ended  December 31,
1997 and 1996 was 23% and 18%, respectively. These increases are attributable to
the  Company's  recent  acquisition  of drilling rig companies and increased rig
utilization and operating efficiencies.

Oil and gas production cost for the six months ended December 31, 1997 increased
by $545,000,  or 42%, to $1,831,000  compared to  $1,286,000  for the six months
ended December 31, 1996. The increased costs were attributable to an increase in
the number of producing oil and gas wells.

General and  administrative  expenses for the six months ended December 31, 1997
increased by $10,774,000, or 148%, to $18,036,000 compared to $7,262,000 for the
six months ended December 31, 1996. The increase was primarily  attributable  to
the  Company's   recent   acquisitions  and  expanded   services.   General  and
administrative  expenses as a  percentage  of total  revenues for the six months
ended December 31, 1997 and 1996 were 9.7% and 10.7%, respectively.

Depreciation,  depletion  and  amortization  expense  for the six  months  ended
December 31, 1997 increased by $8,449,000,  or 190%, to $12,886,000  compared to
$4,437,000  for the six months ended December 31, 1996. The increase is directly
related to the increase in property and equipment  and  long-term  debt issuance
costs incurred by the Company over the past eighteen months in conjunction  with
its acquisitions.

Interest  expense  for the six months  ended  December  31,  1997  increased  by
$4,671,000,  or 177%,  to $7,317,000  compared to $2,646,000  for the six months
ended  December 31, 1996.  The  increase was  primarily  the result of increased
indebtedness as a result of the Company's acquisitions.

Income tax expense for the six months  ended  December  31,  1997  increased  by
$5,582,000,  or 308%,  to $7,395,000  compared to $1,813,000  for the six months
ended  December  31,  1996.  The Company does not expect to have to pay the full
amount of the income tax provision  because of the  availability  of accelerated
tax depreciation, drilling tax credits, and tax loss carryforwards.

Cash Flows

Net cash provided by operating  activities for the six months ended December 31,
1997 increased by $9,494,000, or 493%, to $11,421,000 compared to $1,927,000 for
the six months ended December 31, 1996.  The increase is primarily  attributable
to an increased  service and drilling  operating  margin,  increased service and
drilling  utilization rates,  increased  operating  efficiencies  created by the
acquisitions and price increases for oilfield service and drilling.

Net cash used in investing activities for the six months ended December 31, 1997
increased by $164,087,000, or 779%, to $185,152,000 compared to $21,065,000 used
for the six months ended December 31, 1996.  This increase is primarily  related
to the Company's recent acquisitions.

Net cash provided by financing  activities for the six months ended December 31,
1997 increased by $159,958,000, or 619%, to $185,797,000 compared to $25,839,000
provided  during the six  months  ended  December  31,  1996.  The  increase  is
primarily  the  result  of the  proceeds  from  long-term  debt  (see  Note 3 to
consolidated financial statements).

LIQUIDITY AND CAPITAL RESOURCES

At December 31, 1997,  the Company had cash of $53.8  million  compared to $41.7
million at June 30, 1997 and $9.3 million at December 31, 1996.  At December 31,
1997, the Company had working capital of $99.1 million compared to $60.2 million
at June 30, 1997 and $17.1 million at December 31, 1996.

In addition to its on-going  acquisition  program,  for fiscal 1998, the Company
has projected $40 million of capital  expenditures  for improvements of existing
service and drilling rig machinery and  equipment,  an increase of $23.4 million
over the $16.6 million  expended during fiscal 1997.  Capital  expenditures  for
service and drilling rig improvements for the six months ended December 31, 1997
and 1996 were $22.3 million and $6.5 million,  respectively. The Company expects
to finance these capital  expenditures  through internally  generated  operating
cash flows.

The Company has projected $10.2 million of capital  expenditures for oil and gas
exploration  for fiscal  1998 as compared to $8.2  million  expended  for fiscal
1997. For the six months ended December 31, 1997 and 1996, the Company  expended
$2.3  million and $1.3,  respectively.  Financing  of these costs is expected to
come from operations and available credit facilities.

The Company's  primary capital resources are net cash provided by operations and
proceeds from certain long-term debt facilities.

Long-Term Debt Facilities

On June 6, 1997, the Company entered into the Initial Credit Agreement with PNC,
as  administrative  agent,  and a syndication of other lenders pursuant to which
the  lenders  provided a $255  million  credit  facility,  consisting  of a $120
million seven-year term loan and a $135 million five-year revolver. The interest
rate on the term loan was LIBOR  plus 2.75  percent.  The  interest  rate on the
revolver varied based on the LIBOR and the level of the Company's  indebtedness.
The  Initial  Credit  Agreement  contained  certain  restrictive  covenants  and
required the Company to maintain  certain  financial  ratios.  On September  25,
1997,  the  Company  repaid the term loan and a portion of the then  outstanding
amounts  under the revolver  applying  the proceeds  from the initial and second
closings of the Company's  private  placement of $216 million of 5%  Convertible
Subordinated Notes (discussed below).

Effective  November  6,  1997,  the  Company  entered  into the  Amended  Credit
Agreement  with PNC as  administrative  agent and lender,  pursuant to which PNC
agreed to make revolving credit loans of up to a maximum loan commitment of $200
million.  The maximum  commitment  decreases to $175 million on November 6, 2000
and to $125  million on  November 6, 2001.  The loan  commitment  terminates  on
November 6, 2002

Effective  December 3, 1997, PNC completed the syndication of the Amended Credit
Agreement  and,  in  connection  therewith,  PNC,  as  administrative  agent,  a
syndication  of lenders and the Company  entered  into a First  Amendment to the
Amended and Restated  Credit  Agreement  providing for,  among other things,  an
increase in the maximum commitment from $200 million to $250 million.

At December 31, 1997, the principal balance of the Amended Credit Agreement,  as
amended,   was  $107  million  and  the  unused   credit   facility   aggregated
approximately $143 million,  with approximately $3 million reserved for existing
letters of credit.

<PAGE>

In July 1996, the Company completed a $52,000,000  private offering  Debentures,
pursuant to Rule 144A under the Securities  Act. The Debentures are  subordinate
to the  Company's  senior  indebtedness,  which,  as defined under the indenture
pursuant to which the Debentures were issued,  includes the borrowings under the
Amended Credit Agreement,  as amended.  Interest on the Debentures is payable on
January 1 and July 1 of each year.

As of December 31, 1997,  $47,400,000 in principal  amount of the Debentures had
been  converted  into  5,062,369  shares  of Common  Stock at the  option of the
holders.  The number of shares issued  included  200,831 shares in excess of the
number of shares  issuable  at the  conversion  price of $9.75 per share.  These
additional  shares  were  issued  by the  Company  to  induce  conversion.  Such
additional  consideration  was  accounted  for as an increase  to the  Company's
equity. In addition,  the proportional  amount of debt issuance costs associated
with the converted  Debentures  was accounted for as a decrease to the Company's
equity. At December 31, 1997, $4,600,000 of Debentures remained outstanding.

On September 25, 1997, the Company  completed an initial  closing of its private
placement of $200 million  Notes.  On October 7, 1997,  the Company  completed a
second  closing of its private  placement of an additional  $16 million of Notes
pursuant to the exercise of the remaining portion of the  over-allotment  option
granted to the initial  purchasers of Notes. The placements were made as private
offerings  pursuant to Rule 144A and Regulation S under the Securities  Act. The
Notes are subordinate to the Company's senior indebtedness, which, as defined in
the indenture under which the Notes were issued,  includes the borrowings  under
the Amended Credit  Agreement,  as amended.  Interest on the Notes is payable on
March 15 and September 15, commencing March 15, 1998. The Notes are convertible,
at the holder's  option,  into shares of Common  Stock at a conversion  price of
$38.50 per share, subject to certain adjustments.

Proceeds from the placement of the Notes were used to repay  balances  under the
Company's  credit  facilities  (see above).  At December 31, 1997,  $216,000,000
principal amount of the Notes was outstanding.

Year 2000 Issue

The  Company has made an  assessment  of its Year 2000  issues.  The Company has
determined that certain operating  systems which the Company currently  utilizes
for its financial  reporting  will be adversely  impacted by the year 2000.  The
Company is currently in the process of  selecting a new  operating  system which
will not be adversely impacted by the year 2000. Conversion to the new operating
system is expected to begin on July 1, 1998 and be  completed  by June 30, 1999.
The cost of the new  operating  system  and  conversion  is not  expected  to be
material to the Company's operations or financial condition.

                  None.

       Item 2. Changes in Securities and Use of Proceeds.
 
         (c) Recent Sales of Unregistered Securities:

               During the three  months ended  December  31,  1997,  the Company
          effected the following sales of unregistered securities:

               Effective  October 1, 1997,  the Company issued 125,000 shares of
          Common Stock as part of the  consideration  paid in the acquisition by
          Key Four Corners,  Inc., a wholly-owned  subsidiary of the Company, of
          substantially  all of the  assets  of Big A Well  Service  Co.,  Sunco
          Trucking  Co. and Justis  Supply Co.,  Inc.,  each a closely  held New
          Mexico corporation (collectively,  the "Sellers"). The issuance of the
          Common  Stock to the sole  shareholder  of the Sellers was exempt from
          registration  under  the  Securities  Act of  1933,  as  amended  (the
          "Securities  Act"),  pursuant to Section 4(2), as a sale of securities
          not involving any public offering.

               Effective  October 7, 1997,  the  Company  issued $16  million in
          principal  amount of its 5%  Convertible  Subordinated  Notes due 2004
          (the  "Notes")  pursuant  to an  over-allotment  option  exercised  by
          McMahan  Securities  Co. L.P. and Lehman  Brothers  Inc.,  the initial
          purchasers  in the Company's  September 25, 1997 private  placement of
          the Notes. The Notes are generally  convertible at the holders' option
          at any time  into  shares  of Common  Stock at a  conversion  price of
          $38.50  per  share.   The  issuance  of  the  Notes  was  exempt  from
          registration  under the  Securities  Act because the sale of the Notes
          was only to qualified  institutional  buyers in  compliance  with rule
          144A and outside the United States to persons other than U.S.  persons
          in reliance on Regulation S of the Securities Act.

               Effective  December 2, 1997,  the Company agreed to issue 240,000
          shares of Common  Stock in  connection  with the  purchase by WellTech
          Eastern,   Inc.,  a  wholly-owned   subsidiary  of  the  Company,   of
          substantially all of the assets of White Rhino Drilling,  Inc. ("White
          Rhino"),   S&R  Cable,  Inc.  ("S&R  Cable")  and  Wellcorps,   L.L.C.
          ("Wellcorps"). Of the 240,000 shares to be issued, 212,496 were issued
          to White  Rhino  and its  designees,  72,240 of which  were  issued on
          December  2, 1997 and 140,256 of which were issued on January 2, 1998.
          The  remaining  27,504  shares  were issued to S&R Cable on January 2,
          1998.  The issuance of the Common  Stock was exempt from  registration
          under Section 4(2) of the  Securities  Act as a sale of securities not
          involving any public offering.

investor  in as much as 3% of any  security of any class of any  corporation  or
other business  entity (i) engage in  competition  with GSI,  Purchaser,  or any

any employee of GSI, Purchaser or any affiliate of Purchaser to terminate his or

area set  forth  in this  Section  8 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 8
are in addition to any other obligations that the Seller may have under the laws
of the State of Texas  requiring an employee of a business or a shareholder  who
sells his or her stock in a corporation (including a disposition in a merger) to
limit his or her  activities so that the goodwill and business  relations of his
or her employer and of the  corporation  whose stock he or she has sold (and any
successor  corporation) will not be materially  impaired.  Seller further agrees

adequate  remedy at law for the  breach or  threatened  breach by Seller of this
covenant,  and agree that GSI, Purchaser,  or any affiliate of Purchaser may, in
addition to the other  remedies  which may be available to it hereunder,  file a
suit in equity to enjoin  Seller from such breach or threatened  breach.  If any
provisions  of this Section 8 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 8 are being  executed and delivered by
Seller  in  consideration  of the  covenants  of  Purchaser  contained  in  this
Agreement,  and for other good and valuable  consideration,  receipt of which is
hereby acknowledged.


9. Indemnification.

From  and  after  the date  hereof,  Seller  will  indemnify  and hold  harmless
Purchaser  against any claim,  loss,  liability or expense incurred by Purchaser
and arising out of or  attributable to any inaccuracy of any  representation  or
warranty or any breach of any covenant or agreement  made by Seller herein or in
any instrument or agreement referred to herein or contemplated hereby. Purchaser
will indemnify and hold harmless  Seller against any claim,  loss,  liability or
expense  incurred by Seller and arising out of or attributable to any inaccuracy
of any  representation  or warranty or any breach of any  covenant or  agreement
made by Purchaser herein or in any instrument or agreement referred to herein or
contemplated hereby. As used in this Section 9, "expense" shall include, without
limitation,  attorneys' fees and costs of any investigation of an alleged breach
which is ultimately  determined to constitute a matter for which indemnification
is required.

amount of  $1,000.00  for Seller's  share of all ad valorem  taxes in respect of

such cooperation or expenses paid by the party providing such cooperation to its
officers,  directors,  employees  and agents  while  assisting in the defense or
prosecution of any such litigation or proceeding.

press release  announcing the completion of this asset  acquisition.  Other than

Purchaser,  without further consideration,  Seller will execute and deliver such

investor  in as much as 3% of any  security of any class of any  corporation  or

Production,  Purchaser or any  affiliate  of  Purchaser to terminate  his or her

set forth in this Section 8 is deemed too  restrictive in any court  proceeding,

the circumstances.  The obligations  expressed in this Section 8 are in addition
to any other obligations that the Seller may have under the laws of the State of
Texas  requiring an employee of a business or a shareholder who sells his or her
stock in a corporation (including a disposition in a merger) to limit his or her
activities  so that the goodwill  and business  relations of his or her employer

corporation)  will  not  be  materially  impaired.  Seller  further  agrees  and
acknowledges that Kahlden Production,  Purchaser, and its affiliates do not have
any adequate remedy at law for the breach or threatened breach by Seller of this
covenant, and agree that Kahlden,  Purchaser, or any affiliate of Purchaser may,
in addition to the other remedies which may be available to it hereunder, file a
suit in equity to enjoin  Seller from such breach or threatened  breach.  If any
provisions  of this Section 8 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 8 are being  executed and delivered by
Seller  in  consideration  of the  covenants  of  Purchaser  contained  in  this
Agreement,  and for other good and valuable  consideration,  receipt of which is
hereby acknowledged.

9. Indemnification.

From  and  after  the date  hereof,  Seller  will  indemnify  and hold  harmless
Purchaser  against any claim,  loss,  liability or expense incurred by Purchaser
and arising out of or  attributable to any inaccuracy of any  representation  or
warranty or any breach of any covenant or agreement  made by Seller herein or in
any instrument or agreement referred to herein or contemplated hereby. Purchaser
will indemnify and hold harmless  Seller against any claim,  loss,  liability or
expense  incurred by Seller and arising out of or attributable to any inaccuracy
of any  representation  or warranty or any breach of any  covenant or  agreement
made by Purchaser herein or in any instrument or agreement referred to herein or
contemplated hereby. As used in this Section 9, "expense" shall include, without
limitation,  attorneys' fees and costs of any investigation of an alleged breach
which is ultimately  determined to constitute a matter for which indemnification

                              Additional Agreements

3.1. Noncompetition.  Except as otherwise consented to or approved in writing by
Buyer,  the  Shareholder  agrees  that for a period of 42  months  from the date
hereof,  he 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 5% of any  security  of any class of any
corporation or other business entity (i) engage in competition with the business
or businesses conducted by the Company, any of the Company Subsidiaries,  on the
date hereof,  or in any service  business the services of which are provided and

any state of the United States, or any foreign country in which the Company, any
of the Company Subsidiaries, transacts business on the date hereof; (ii) request
any  present  customers  or  suppliers  of  the  Company,  any  of  the  Company
Subsidiaries,  to curtail or cancel their business with the Company,  any of the

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


3.2.  Facility Lease.  From the date hereof,  the  Shareholder  hereby agrees to
lease to the Company its current  facilities in Woodward,  Oklahoma  pursuant to
the terms and provisions of those certain Lease Agreements of even date herewith
by and between  the  Company  and the  Shareholder  executed  and  delivered  in
connection herewith.

3.3. Further  Assurances.  From time to time, as and when requested by any party
hereto,  any other  party  hereto  shall  execute  and  deliver,  or cause to be
executed and delivered,  such documents and instruments and shall take, or cause

                                 Indemnification

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

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

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

2.2.  Representations  and Warranties of Buyer. Buyer represents and warrants to
the Shareholders as follows

2.2.1.  Organization  and Good Standing.  Buyer is a corporation duly organized,

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.

2.2.2.   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 Buyer,  and this
Agreement is a valid and binding  obligation  of Buyer  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 Buyer will not conflict
with or  result  in a  violation  or  breach  of any term or  provision  of,  or
constitute a default under (a) the  Certificate  of  Incorporation  or Bylaws of
Buyer or (b) any obligation, indenture, mortgage, deed of trust, lease, contract
or other agreement to which Buyer or any of its property is bound.

2.2.3.  Consents and Approvals.  No consent,  approval or  authorization  of, or
filing of a registration with, any governmental or regulatory authority,  or any
other person or entity is required to be made or obtained by Buyer in connection
with  the   execution,   delivery  or  performance  of  this  Agreement  or  the
consummation of the transactions contemplated hereby.

2.2.4.  Finder's  Fee.  All  negotiations  relative  to this  Agreement  and the
transactions  contemplated  hereby have been carried on by Buyer and its counsel
directly with the Companies and the Shareholders and their counsel,  without the
intervention  by 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 payments.

                              Additional Agreements

3.1. Noncompetition.  Except as otherwise consented to or approved in writing by
Buyer,  each  Shareholder  agrees  that for a period of 60 months  from the date
hereof, he or she 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 5% of any  security of any
class of any corporation or other business entity (i) engage in the contract oil
and gas  drilling  business  within a two hundred  (200) mile radius of Abilene,
Texas,  (ii)  request  any  present  customers  or  suppliers  of  either of the
Companies,  Buyer or any affiliate of Buyer to curtail or cancel their  business
with either of the Companies, Buyer or any affiliate of Buyer; (iii) disclose to
any person, firm or corporation any trade, technical or technological secrets of
either of the Companies, Buyer or any affiliate of Buyer or any details of their
organization or business affairs or (iv) induce or actively attempt to influence
any  employee of either of the  Companies,  Buyer or any  affiliate  of Buyer to
terminate his employment.  Each Shareholder  agrees that if either the length of
time  or  geographical  area  set  forth  in  this  Section  3.1 is  deemed  too
restrictive in any court  proceeding,  the court may reduce such restrictions to
those  which  it deems  reasonable  under  the  circumstances.  The  obligations
expressed in this Section 3.1 are in addition to any other  obligations that the
Shareholders  may have under the laws of the  states in which  they do  business
requiring an employee of a business or a  Shareholders  who sells his stock in a
corporation (including a disposition in a merger) to limit his or her activities
so that the goodwill  and  business  relations of his or her employer and of the
corporation whose stock he or she has sold (and any successor  corporation) will
not be materially  impaired.  Each  Shareholder  further agrees and acknowledges
that the Companies,  Buyer and its affiliates do not have any adequate remedy at
law for the breach or threatened  breach by the  Shareholders  of this covenant,
and agree that each of the  Companies,  Buyer or any  affiliate of Buyer may, in
addition to the other remedies which may be available to them hereunder,  file a
suit in equity to enjoin the Shareholders 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 Shareholder
acknowledges that the covenants set forth in this Section 3.1 are being executed
and delivered by the  Shareholders  in  consideration  of the covenants of Buyer
contained  in this  Agreement,  and for other good and  valuable  consideration,
including  the payment of the sum of $50,000,  receipt of all of which is hereby
acknowledged.

3.2. Further  Assurances.  From time to time, as and when requested by any party
hereto,  any other  party  hereto  shall  execute  and  deliver,  or cause to be
executed and delivered,  such documents and instruments and shall take, or cause
to be taken,  such further or other  actions as may be  reasonably  necessary to
effectuate the transactions contemplated hereby.

3.3.  Companies=  Stock  Not  Registered.  Each  Company  is  a  privately  held
corporation and Buyer acknowledges such. The stock of the Companies 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 other such state
laws as may be applicable.  Buyer  acknowledges  that the Shareholders have made
available to it such information and documents,  and that Buyer  understands the
risk associated with ownership of the capital stock of the Companies,  and Buyer
is capable of bearing the financial risk  associated  therewith.  The Companies=
shares and the dealings with Buyer are proceeding in reliance on exceptions from
registration or qualification requirements pursuant to state law.

3.4.  Opinion of  Shareholders=  Counsel.  Buyer shall have received a favorable
opinion,  dated as of the date hereof, from George Scott Bishop,  counsel to the
Shareholders,  in form and substance  satisfactory  to Buyer, to the effect that
(i) each of the Companies has been duly  incorporated and is validly existing as
a corporation and is in good standing under the laws of the State of Texas; (ii)
each of the Companies has fully requisite corporate power and authority to carry
on  its  business  as it is  currently  conducted  and to own  and  operate  the
properties  currently  used and  operated  by it,  and is duly  qualified  to do
business and is in good standing as a foreign corporation in each state in which
the nature of its business  requires such  qualification;  (iii) all outstanding
shares of the common stock of each of the Companies have been validly issued and
are fully paid and  non-assessable;  (iv) the  Shareholders  hold good and valid
title  to all of the  shares  of each of the  Companies  free  and  clear of all
Encumbrances;  and (v) this  Agreement  has been duly executed and delivered by,
and is the legal,  valid and  binding  obligation  of the  Shareholders,  and is
enforceable against the Shareholders in accordance with its terms, except as the
enforceability   may  be  limited  by  (a)   equitable   principles  of  general
applicability  or  (b)  bankruptcy,   insolvency,   reorganization,   fraudulent
conveyance  or similar  laws  affecting  the rights of creditors  generally.  In
rendering  such  opinion,  such  counsel  may rely upon  certificates  of public
officials  and of officers of each of the  Companies or the  Shareholders  as to
matters of fact.

3.5.  Opinion of Buyer=s Counsel.  Shareholders  shall have received a favorable
opinion,  dated  as of  the  date  hereof,  from  Lynch,  Chappell  &  Alsup,  a
Professional Corporation,  counsel for Buyer, in form and substance satisfactory
to the Shareholders, to the effect that (i) Buyer has been duly incorporated and
is validly  existing as a  corporation  in good  standing  under the laws of the
State of Delaware and 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 the State of Texas;  (ii) all corporate  proceedings  required to be
taken by or on the part of Buyer to authorize  the  execution of this  Agreement
and the implementation of the transactions  contemplated hereby have been taken;
(iii) this  Agreement has been duly executed and delivered by, and is the legal,
valid and  binding  obligation  of Buyer  and is  enforceable  against  Buyer in
accordance with its terms,  except as the  enforceability  may be limited by (a)
equitable  principles of general  applicability  or (b) bankruptcy,  insolvency,
reorganization,  fraudulent  conveyance or similar laws  affecting the rights of
creditors  generally.  In  rendering  such  opinion,  such counsel may rely upon
certificates of public officials and of officers of Buyer as to matters of fact.

3.6.  Fees  and  Expenses.  Except  as  otherwise  expressly  provided  in  this
Agreement,  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 or expense by or on the date hereof.

                                    ARTICLE 4

                                 Indemnification

4.1.  Indemnification  by the  Shareholders.  In addition to any other  remedies
available  to  Buyer  under  this  Agreement,  or  at  law  or  in  equity,  the
Shareholders  shall  indemnify,  defend and hold harmless each of the Companies,
Buyer and their affiliates and their respective officers, directors,  employees,
agents and stockholders (collectively, the "Buyer Indemnified Parties"), against
and with  respect  to any and all  claims,  costs,  damages,  losses,  expenses,
obligations,  liabilities, recoveries, suits, causes of action and deficiencies,
including  interest,  penalties and  reasonable  fees and expenses of attorneys,
consultants and experts (collectively, the "Damages") that the Buyer Indemnified
Parties  shall incur or suffer,  which  arise,  result from or relate to (i) any
breach by the  Shareholders  of (or the failure of the  Shareholders to perform)
their representations,  warranties, covenants or agreements in this Agreement or
in any schedule, certificate, exhibit or other instrument furnished or delivered
to Buyer by the  Shareholders  under this  Agreement  (including,  specifically,
those set forth in Section 2.1.17 hereto),  (ii) the ownership  and/or operation
by either of the Companies of those assets distributed to the Shareholders prior
to the date hereof  (which are  described in Schedule  2.1.10  hereto),  and the
assumption by the  Shareholders of the  liabilities  applicable to those assets.
Notwithstanding  the  foregoing,  the  Shareholders'  obligations  to indemnify,
defend and hold harmless the Buyer Indemnified Parties for liabilities resulting
from  Damages  that the  Buyer  Indemnified  Parties  may incur as a result of a
breach of the representations  and warranties  contained in Section 2.1.17 above
shall be limited to those Damages which exceed $150,000 in the aggregate.

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

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

shareholder and other action on the part of the Seller and the Shareholder,  and

Shareholder 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  Shareholder  is a  party  or by  which  the  Seller  or the

not in default, and to the knowledge of Seller and Shareholder no other party to
any of the Contracts is in default,  thereunder, and no event has occurred which

Seller  will  (or is  likely  to)  cease  doing  business  with  Buyer  (or  its
successors) as a result of the  consummation  of the  transactions  contemplated
hereby. All of the Contracts are assignable (and are hereby validly assigned) to

regulatory  agency  or in  accordance  with  applicable  laws.  On and after the
Effective  Date,  to the  knowledge  of Seller and the  Shareholder  each of the
Seller  Permits  and  Buyers  rights  with  respect  thereto  will be valid  and

complete in all material  respects and presents  fairly and fully the  financial
condition  of the  Seller on that date and for the period  indicated  thereon as
accounted for under a tax basis accounting.  The Seller Financial  Statement has

To the  knowledge  of the  Seller or the  Shareholder,  the Assets  include  all

applicable   Environmental  Law.  There  are  no  environmental   conditions  or
circumstances  caused by Seller in whole or in part or  exacerbated  by  Seller,

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 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 the Seller or the Shareholder is a
party or, to the  knowledge  of the Seller or the  Shareholder,  might  become a
party which would  adversely  affect the Assets or the Buyers future  conduct of
the Businesses.

or other person who is or may be in a position to help or hinder the  profitable

unliquidated, absolute fixed or contingent, disputed or undisputed or secured or
unsecured.

II.1.15. Untrue Statements.  This Agreement and all other agreements executed by
the Seller or the  Shareholder  and  delivered to Buyer in  connection  with the
transaction  contemplated  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  Contracts,   documents  concerning  all
litigation  and  administrative   proceedings,   Licenses,   Permits,  insurance
policies,  lists of suppliers and customers, and records relating principally to

parties hereto for a brokerage commission, finders fee or any similar payment.

II.1.17.  Taxes.  All taxes of the  Seller  with  respect  to the Assets and the
Businesses for that period of time before the Effective Date,  including any and

II.2 Investment  Representations  of the Seller and the Shareholder.  The Seller
and Shareholder acknowledge, represent and agree that:

(a)  Each of the Seller and Jordan Exploration  Company,  L.L.C. ( collectively,
     the Key Share Recipients) is an accredited investor as such term is defined
     in  Regulation  D  under  the  Securities  Act of  1993,  as  amended  (the
     Securities Act).

<PAGE>


(b)  (i) Each Key Share Recipient,  through its own operations, is knowledgeable
     in operations of the type  conducted by Key, (ii) Key has made available to
     each Key Share Recipient extensive legal,  financial,  accounting and other
     business records for examination by each Key Share Recipient, (iii) Key has
     made  its  principal   executive  and  operating  personnel  available  for
     consultation  with  the  designated   representatives  of  each  Key  Share
     Recipient,   (iv)  each  Key  Share   Recipient   has  made  an   extensive
     investigation  of Keys  assets  and  liabilities,  business  and  financial
     affairs, and operations, (v) each Key Share Recipient is aware of the risks
     associated with ownership of the Key Shares,  (vi) each Key Share Recipient
     is capable of bearing the financial  risks  associated with such ownership,
     and  (vii)  while   recognizing  that  it  cannot   effectively  waive  the
     protections  afforded  to it under  the  Securities  Act,  each  Key  Share
     Recipient  regards  itself  as  an  entity  of  such  financial   capacity,
     sophistication,  and  prudence  that it does not  require  the  protections
     afforded  to it by  the  Securities  Act,  and  is  relying  upon  its  own
     investigation of Key in making its 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 each Key Share  Recipient  in  reliance
     upon exemptions from such registration or qualification  requirements,  and
     the  availability  of such  exemptions  depends  in part upon the bona fide
     investment  intent of Seller and the  Shareholder  with  respect to the Key
     Shares;

(e)  The acquisition of the Key Shares by each Key Share Recipient is solely for
     its own  account  for  investment,  and each  Key  Share  Recipient  is not
     acquiring the Key Shares for the account of any other person or with a view
     toward resale, assignment, fractionalization, or distribution thereof. This
     representation  does not prohibit any Key Share  Recipient  from making any
     sale or transfer not otherwise prohibited by law or this Agreement;

(f)  Each Key Share Recipient 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, each Key Share Recipient must bear the
     economic risk of holding the Key Shares for an  indefinite  period of time,
     and each Key Share Recipient 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:



<PAGE>

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

such scope,  any right to  arbitrate  shall be barred.  Further the scope of any
arbitration shall be limited solely to the issue of amount of any adjustments to
the  purchase  price  pursuant to this section and shall not extend to any other

<PAGE>


   
V.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,  the
Seller and the Shareholder shall, jointly and severally,  indemnify,  defend and
hold  harmless  Buyer  and  its  officers,  directors,   employees,  agents  and
stockholders  (collectively,  the Buyer Indemnified Parties@),  against and with
respect to any and all claims, costs, damages,  losses,  expenses,  obligations,
liabilities,  recoveries,  suits,  causes of action and deficiencies,  including
interest,  penalties and reasonable attorneys= fees and expenses  (collectively,
the Damages@) that any of the Buyer  Indemnified  Parties shall incur or suffer,
which  arise,  result  from or relate to (i) any  breach  of, or  failure by 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) except to the extent
the Damages are  exacerbated  by Buyer or Key,  the  Retained  Liabilities.  The
indemnification obligations of Seller and the Shareholder under this Section 5.1
shall not exceed the Purchase Price; provided, however, that the indemnification
obligations  of Seller and the  Shareholder  under this  Section 5.1 for Damages
incurred or  suffered  which  arise from or relate to the  Retained  Liabilities
shall be unlimited in amount.

V.2  Indemnification  by Buyer  and  Key.  In  addition  to any  other  remedies
available to the Seller and the Shareholder  under this Agreement,  or at law or
in equity,  Buyer and Key shall,  jointly and severally,  indemnify,  defend and

directors, employees and agents (collectively,  the Seller Indemnified Parties@)
against  and  with  respect  to any  and  all  Damages  that  any of the  Seller
Indemnified Parties shall incur or suffer, which arise, result from or relate to
(i)  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 the
Seller or the  Shareholder by or on behalf of Buyer or Key under this Agreement;
and (ii) except to the extent  that any Damages  arise out of a breach by Seller
and/or  Shareholder of any of their  respective  representations,  warranties or
covenants  contained herein, any Damages arising out of the use of the Assets by
Buyer after the Effective Date.


<PAGE>

V.3  Indemnification  Procedure.  If any party  hereto  discovers  or  otherwise
becomes  aware of an  indemnification  claim arising under Section 5.1 or 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
amount of the claim is not  increased  by the timing of, or failure to give such
notice.  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 amount of the claim is not increased by
the  timing  of, or  failure  to give such  notice.  In case any such  action is
brought against an indemnified  party, the indemnifying  party shall be entitled
to  participate  in and to assume the defense  thereof,  jointly  with any other
indemnifying  party  similarly  notified,  to the extent that it may wish,  with
counsel reasonably satisfactory to such indemnified party, and after such notice
from the  indemnifying  party to such  indemnified  party of its  election so to
assume the defense thereof,  the indemnifying  party shall not be liable to such
indemnified party for any legal or other expenses  subsequently  incurred by the
latter in connection with the defense thereof unless the indemnifying  party has
failed to assume  the  defense of such  claim and to employ  counsel  reasonably
satisfactory to such indemnified person. An indemnifying party who elects not to
assume the defense of a claim  shall not be liable for the fees and  expenses of
more than one counsel in any single  jurisdiction for all parties indemnified by
such  indemnifying  party with  respect to such claim or with  respect to claims
separate but similar or related in the same jurisdiction arising out of the same
general allegations.  Notwithstanding any of the foregoing to the contrary,  the
indemnified  party will be  entitled  to select its own  counsel  and assume the
defense of any action  brought  against it if the  indemnifying  party  fails to
select counsel reasonably satisfactory to the indemnified party, the expenses of
such defense to be paid by the indemnifying  party. No indemnifying  party shall
consent to entry of any judgment or enter into any settlement  with respect to a
claim without the consent of the indemnified  party,  which consent shall not be
unreasonably  withheld,  or unless such  judgment or  settlement  includes as an
unconditional  term  thereof  the giving by the  claimant or  plaintiff  to such
indemnified party of a release from all liability with respect to such claim. No
indemnified  party  shall  consent  to entry of any  judgment  or enter into any
settlement  of any such  action,  the  defense  of which has been  assumed by an
indemnifying  party,  without  the  consent of such  indemnifying  party,  which
consent shall not be unreasonably withheld or delayed.

                                  Miscellaneous

<PAGE>



II.1.2. Agreement Authorized and its Effect on Other Obligations.  The execution
and delivery of this Agreement have been authorized by all necessary  corporate,
shareholder  and  other  action  on the  part  of the  Seller  and  each  of the
Shareholders,  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 any of the  Shareholders is a party or by
which the Seller or any of the Shareholders or their  respective  properties are
bound;  or  (iii)  to the  knowledge  of the  Seller  and the  Shareholders  any
provision  of any law,  rule,  regulation,  order,  permit,  certificate,  writ,
judgment,  injunction,  decree,  determination,  award or other  decision of any
court, arbitrator, or other governmental authority to which the Seller or any of
the Shareholders or any of their respective properties are subject.

II.1.3.  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
Effective  Date.  All of the  Contracts  are  in  full  force  and  effect,  and
constitute valid and binding obligations of the applicable Seller. The Seller is
not in default,  and to the knowledge of Seller and  Shareholders 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 an adverse effect on the use
of the  Assets by  Buyer.  The  Seller  or the  Shareholders  have  received  no
information  which would cause any of such parties to conclude that any customer
of the Seller  will (or is likely to) cease  doing  business  with Buyer (or its
successors) as a result of the  consummation  of the  transactions  contemplated
hereby. All of the Contracts are assignable (and are hereby validly assigned) to
Buyer without the consent of any other party  thereto,  or such consent has been
received.

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).  To the knowledge of Seller and Shareholders 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. 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 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.


<PAGE>



II.1.5. 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 Sellers  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 and further subject to applicable laws. The Seller
is in compliance  in all material  respects with the terms of each of the Seller
Permits.  The Seller  Permits have not been, or are not, to the knowledge of the
Seller  or  any of  the  Shareholders,  threatened  to  be,  revoked,  canceled,
suspended or modified.  To the  knowledge  of Seller and each  Shareholder  upon
consummation of the transactions  contemplated hereby, all of the Seller Permits
shall be  assignable  (and are hereby  assigned) to Buyer without the consent of
any regulatory  agency or in accordance with  applicable  laws. On and after the
Effective  Date,  to the  knowledge of Seller and each  Shareholder  each of the
Seller  Permits  and  Buyers  rights  with  respect  thereto  will be valid and
subsisting in full force and effect,  and  enforceable  by Buyer subject only to
the administrative  powers of regulatory  agencies having  jurisdiction over the
assigned Seller Permits and applicable laws.

II.1.6. Intellectual Property. Schedule 1.1(c) hereto sets forth a complete list
of all Intellectual  Property material to or necessary for the continued conduct
of the Assets.

II.1.7.  Financial  Statements.  The Seller has  delivered to Buyer copies of an
unaudited  financial  statement of Seller, a copy of which is attached hereto as
Schedule  2.1.7 (the Seller  Financial  Statement),  and  includes an  unaudited
balance  sheet (the  Unaudited  Balance  Sheet) as of  September  30,  1997 (the
Balance  Sheet  Date).  The Seller  Financial  Statement  is true,  correct  and
complete in all material  respects and presents  fairly and fully the  financial
condition  of the  Seller on that date and for the period  indicated  thereon as
accounted for under a tax basis accounting.  The Seller Financial  Statement has
been  prepared  using a tax basis for  management  purposes  only.  The  account
classifications have been determined to derive the best tax benefit for the
Shareholders.

II.1.8.  Absence of Certain  Changes and Events.  Since the Balance  Sheet Date,
there has not been:
     (a)  Financial  Change.  Any  material  adverse  change in the Assets,  the
          Businesses  or the financial  condition,  operations,  liabilities  or
          prospects of the Seller;

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

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



<PAGE>



     (d)  Change  in  Assets.  Except  as set forth on  Schedule  2.1.8(d),  any
          material acquisition,  disposition,  transfer, encumbrance,  mortgage,
          pledge or other  encumbrance  of any Asset of the Seller other than in
          the ordinary course of business or other than the Excluded Assets;

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

     (f)  Other Changes. Any other event or condition known to the Seller or any
          of the  Shareholders  that  particularly  pertains to and has or might
          have a material  adverse  effect on the Assets,  the operations of the
          Businesses or the financial condition or prospects of the Seller.

For the purposes of this Section 2.1.8 a change will be considered material if
it has a value of $10,000, or more.

II.1.9.  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,  if any,  in order to
validly  transfer  the Assets  hereunder,  including,  without  limitation,  any
consents required to assign the Contracts and the Seller Permits.



<PAGE>



II.1.10.  Environmental  Matters. To the knowledge of Seller none of the current
or past  operations  of any of the  Businesses or any of the Assets are being or
have been conducted or used in such a manner as to constitute a violation of any
Environmental  Law (defined below).  The Seller or the Shareholders has received
no 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  Environmental  Law or
regarding any claims for remedial  obligations or contribution for removal costs
or damages under any Environmental Law. 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 any of the
Shareholders,   threatened  relating  to  the  ownership,  use,  maintenance  or
operation of the Assets or the conduct of the Businesses,  nor, to the knowledge
of the  Seller  or any of the  Shareholders,  is there  any basis for any of the
foregoing.  To the  knowledge  of Seller  Buyer is not  required  to obtain  any
permits, licenses or similar authorizations pursuant to any Environmental Law in
effect as of the  Effective  Date to operate and use any of the Assets for their
current  purposes  and  uses.  To  the  knowledge  of the  Seller  or any of the

II.2 Investment  Representations of the Seller and the Shareholders.  The Seller
and Shareholders acknowledge, represent and agree that:

     (a)  The Seller (the Key Share Recipient) is an accredited investor as such
          term is defined in Regulation D under the  Securities  Act of 1993, as
          amended (the Securities Act).



<PAGE>



     (b)  (i)  Each  Key  Share  Recipient,   through  its  own  operations,  is
          knowledgeable in operations of the type conducted by Key, (ii) Key has
          made available to each Key Share Recipient extensive legal, financial,
          accounting  and other  business  records for  examination  by each Key
          Share  Recipient,  (iii)  Key has made  its  principal  executive  and
          operating  personnel  available for  consultation  with the designated
          representatives  of each Key  Share  Recipient,  (iv)  each Key  Share
          Recipient  has made an  extensive  investigation  of Keys  assets and
          liabilities,  business and financial affairs, and operations, (v) each
          Key Share Recipient is aware of the risks associated with ownership of
          the Key Shares,  (vi) each Key Share  Recipient  is capable of bearing
          the financial risks  associated  with such ownership,  and (vii) while
          recognizing that it cannot effectively waive the protections  afforded
          to it under  the  Securities  Act,  each Key Share  Recipient  regards
          itself as an entity of such financial  capacity,  sophistication,  and
          prudence  that it does not require the  protections  afforded to it by
          the Securities Act, and is relying upon its own  investigation  of Key
          in making its 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 each Key  Share  Recipient  in
          reliance  upon  exemptions  from such  registration  or  qualification
          requirements,  and the availability of such exemptions depends in part
          upon the bona fide  investment  intent of Seller and the  Shareholders
          with respect to the Key Shares;

     (e)  The  acquisition  of the Key  Shares  by each Key Share  Recipient  is
          solely  for its  own  account  for  investment,  and  each  Key  Share
          Recipient is not acquiring the Key Shares for the account of any other
          person or with a view toward resale, assignment, fractionalization, or
          distribution  thereof.  This  representation does not prohibit any Key
          Share  Recipient  from  making  any  sale or  transfer  not  otherwise
          prohibited by law or this Agreement;

     (f)  Each Key Share  Recipient  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,  each Key Share Recipient must
          bear the  economic  risk of holding  the Key Shares for an  indefinite
          period of time,  and each Key Share  Recipient  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

          prior to the Effective  Date,  including any and all sales taxes,  use
          taxes,  unemployment  compensation  taxes or taxes  arising out of the
          fact that Seller hired employees.

     (d)  The Seller  shall pay all other costs or  expenses  arising out of the
          Assets or the Businesses prior to the Effective Date.

     (e)  The Buyer shall pay all sales taxes and/or use taxes, if any,  charged

     (f)  The Buyer shall pay all costs or expenses arising out of the Assets or
          the use of the Assets by the Buyer after the Effective Date.

IV.8 Issuance of Key Shares. On the Effective Date, Key shall file an additional
Listing  Application with the American Stock Exchange  requesting the listing of
Key Shares  (the  Listing  Application).  In  addition,  Key shall send  written
instructions  to its transfer  agent to issue,  countersign  and register one or
more  certificates  representing  the Key  Shares  in the name of the Key  Share
Recipients in accordance with Section 1.2(b) and deliver such  certificate(s) to
Seller at the address  specified  in Section  6.4 hereof.  In the event that the
American Stock Exchange does not approve the Listing Application by December 15,
1997,  the  parties  hereto  shall  negotiate  in  good  faith  the  appropriate
consideration to replace such shares.

If the parties are unable to resolve any issue as to the  adjustments to be made
pursuant to the  preceding  sentence  within thirty (30) days after the closing,
then  either  party,  within  fifteen  (15) days  thereafter,  but no later than
forty-five  (45) calendar days after the closing,  may file for  arbitration  in
accordance  with the rules of the American  Arbitration  Association  (AAA) then
currently  in  effect,  with  arbitration  to take  place  in  Isabella  County,
Michigan,  or such other place as the parties shall agree.  Notice of demand for
arbitration shall be filed in writing with the other party to this agreement and
with AAA. The award rendered by the  arbitrator or  arbitrators  shall be final,
and judgment may be entered on it in accordance with applicable law in any court
having  jurisdiction  on the matter.  However,  the time for filing  arbitration
shall  be of the  essence  and  shall be  strictly  limited  to the time  period
provided in this agreement, and the timely filing shall be a condition precedent
to the exercise of the right of arbitration;  if arbitration is not filed within
such scope,  any right to  arbitrate  shall be barred.  Further the scope of any
arbitration shall be limited solely to the issue of amount of any adjustments to
the  purchase  price  pursuant to this section and shall not extend to any other
issue or matter that may arise out of this agreement.  The arbitrator shall have
no power or authority  to order or determine  any thing or matter other than the
dollar amount of, and procedure for payment of, any adjustment.

IV.9 Registration Rights.

IV.9.1.  Agreement to Register  Resales.  Key agrees that no later than December
31, 1997,  it will file with the  Commission  on Form S-3, or if Form S-3 is not
available to Key, on such other form as is available to Key for  registration of
its securities under the Securities Act, a shelf registration statement pursuant
to Rule 415 of the Securities Act (the "Shelf Registration  Statement") covering
the offer and  resale by the Key  Share  Recipient  of 11,460 of the Key  Shares
issued pursuant to this Agreement (herein the Covered Shares) and will use its
best efforts to cause the Shelf Registration  Statement to be declared effective
by March 31,  1998,  by the  Commission.  The Covered  Shares shall be issued as
follows:

                           11,460 Key Shares: Seller



<PAGE>



IV.9.2.  Effectiveness of Shelf Registration  Statement.  Key agrees to maintain
the Shelf  Registration in effect until the earlier of (i) the date that the Key
Share Recipient can transfer the Covered Shares without restriction  pursuant to
Rule 144  promulgated  under the Securities Act (or any successor rule) and (ii)
the date that the Key Share  Recipient no longer own any of the Covered  Shares.
In addition, Key shall amend the Shelf Registration Statement and supplement the
prospectus  included  therein as and when required by Form S-3 or the applicable
form, or by the  Securities  Act. Key shall  promptly  deliver upon request from
time to time to Key Share Recipient  copies of the prospectus,  as supplemented,
in order to facilitate resale of the Covered Shares.

IV.9.3.  Blue Sky Qualification.  In any offering pursuant to this Section,  Key
will use its best  efforts  to  effect  any such  registration  and use its best
efforts to effect such  qualification  and  compliance as may be required and as
would permit or facilitate the resale of such Covered Shares, including, without
limitation,  registration under the Securities Act,  appropriate  qualifications
under  applicable  blue-sky  or other  state  securities  laws and,  appropriate
compliance with any other governmental requirements.

IV.9.4.  Registration  Expenses. All expenses (except for any legal fees for the
Key Share  Recipients  counsel)  relating to the obligations of Key pursuant to
this  Section  4.9  (including,   but  not  limited  to,  the  expenses  of  any
qualifications  under the blue-sky or other state securities laws and compliance
with  governmental  requirements  of  preparing  and filing  any  post-effective
amendments or prospectus supplements required for the lawful distribution of the
Covered Shares to the public in connection with such  registration) will be paid
by Key.

IV.9.5. Rights Non-Transferable.  The registration rights under this Section 4.9
are for the sole benefit of the Key Share Recipient, are personal in nature, and
shall not be transferrable or otherwise available to any subsequent  shareholder
of  the  Covered  Shares;  provided,  however,  that  Seller  may  transfer  its
registration  rights under this Section 4.9 to the Shareholders in the event the
Covered Shares are distributed to the Shareholders,  and upon such transfer, the
Shareholder shall have all of the rights, duties and obligations of Seller under
this Section 4.9 with respect to the Covered Shares so transferred.



<PAGE>



IV.9.6.  Undertaking to File Reports and Cooperate in Transactions.  For as long
as Key Share  Recipient is subject to Rule 144 or Rule 145 of the Securities Act
with respect to the Key Shares,  Key will use reasonable  commercial  efforts to
timely file all annual,  quarterly and other  reports  required to be file by it
under Section 13 or 15(d) of the Exchange Act and the rules and  regulations  of
the  Commission  thereunder,  as  amended  from  time to  time,  or  make  other
information  publicly  available  as required by Rule 144 or 145 (or such Rules
successor).  If the Key  Share  Recipient  proposes  to sell any of the  Covered
Shares pursuant to the Shelf Registration,  or any of the Key Shares pursuant to
Rule 144 or Rule 145, Key shall cooperate with the Key Share Recipients so as to
enable  such sales to be made in  accordance  with  applicable  laws,  rules and
regulations,  the  requirements  of Key's  transfer  agent,  and the  reasonable
requirements  of the broker through which the sales are proposed to be executed.
Without  limiting the  generality  of the  foregoing,  Key shall,  upon request,
furnish with respect to each such sale (i) a written  statement  certifying that
Key has complied with the public  information  requirements  of Rule 144 and 145
and (ii) an opinion of Key's counsel  regarding  such matters as Key's  transfer
agents or such Key Share Recipients broker may reasonably request.

IV.9.7. Remedies. As long as an Event of Default (as defined below) has occurred
and is continuing  on the date that Key receives the Default  Notice (as defined
below),  Key shall,  upon receipt of written  notice from a Key Share  Recipient
(the Default  Notice) and within ten (10) days of receiving the Default  Notice,
purchase those number of Covered  Shares still owned by the Key Share  Recipient
specified in the Default Notice at a price equal to the average closing price of
Key Common Stock on the American Stock  Exchange,  or if the Key Common Stock is
not trading on the American Stock Exchange on the applicable trading day, on the
national  securities exchange on which Key Common Stock was traded on such date,
for the twenty (20)  trading  days  immediately  preceding  the day on which Key
receives the Default  Notice.  As used in this Section 4.9.7,  the term Event of
Default means the occurrence of (i) Keys failure to cause the Shelf Registration
Statement to be declare effective by the Commission on or before March 31, 1998,
or (ii) Keys failure to maintain  the  effectiveness  of the Shelf  Registration
Statement as herein required.

IV.10 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 V

                                 Indemnification

V.1 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 (collectively, the Buyer Indemnified Parties), against and with
respect to any and all claims, costs, damages,  losses,  expenses,  obligations,
liabilities,  recoveries,  suits,  causes of action and deficiencies,  including
interest,  penalties and reasonable  attorneys fees and expenses  (collectively,
the Damages)  that any of the Buyer  Indemnified  Parties shall incur or suffer,
which  arise,  result  from or relate to (i) any  breach  of, or  failure by the
Seller 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 any of the Shareholders  under this Agreement;  and (ii) except to the
extent  that  the  Damages  are  exacerbated  by  Buyer  or  Key,  the  Retained
Liabilities.  The  indemnification  obligations  of Seller and the  Shareholders
under this Section 5.1 shall not exceed the Purchase Price;  provided,  however,
that the  indemnification  obligations of Seller and the Shareholders under this
Section 5.1 for Damages  incurred or suffered  which arise from or relate to the
Retained Liabilities shall be unlimited in amount.


<PAGE>



V.2  Indemnification  by Buyer  and  Key.  In  addition  to any  other  remedies
available to the Seller and the Shareholders under this Agreement,  or at law or
in equity,  Buyer and Key shall,  jointly and severally,  indemnify,  defend and
hold  harmless  the Seller  and each of the  Shareholders  and their  respective
officers, directors, employees and agents (collectively,  the Seller Indemnified
Parties)  against and with respect to any and all Damages that any of the Seller
Indemnified Parties shall incur or suffer, which arise, result from or relate to
(i)  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 the
Seller or any of the  Shareholders  by or on  behalf of Buyer or Key under  this
Agreement;  and (ii) except to the extent that the Damages arise out of a breach
by Seller or Shareholders of any of their respective representations, warranties
or covenants  contained herein, any Damages arising out of the use of the Assets
by Buyer after the Effective Date.



<PAGE>



V.3  Indemnification  Procedure.  If any party  hereto  discovers  or  otherwise
becomes  aware of an  indemnification  claim arising under Section 5.1 or 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
amount of the claim is not  increased  by the timing of, or failure to give such
notice.  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 amount of the claim is not increased by
the  timing  of, or  failure  to give such  notice.  In case any such  action is
brought against an indemnified  party, the indemnifying  party shall be entitled
to  participate  in and to assume the defense  thereof,  jointly  with any other
indemnifying  party  similarly  notified,  to the extent that it may wish,  with
counsel reasonably satisfactory to such indemnified party, and after such notice
from the  indemnifying  party to such  indemnified  party of its  election so to
assume the defense thereof,  the indemnifying  party shall not be liable to such
indemnified party for any legal or other expenses  subsequently  incurred by the
latter in connection with the defense thereof unless the indemnifying  party has
failed to assume  the  defense of such  claim and to employ  counsel  reasonably
satisfactory to such indemnified person. An indemnifying party who elects not to
assume the defense of a claim  shall not be liable for the fees and  expenses of
more than one counsel in any single  jurisdiction for all parties indemnified by
such  indemnifying  party with  respect to such claim or with  respect to claims
separate but similar or related in the same jurisdiction arising out of the same
general allegations.  Notwithstanding any of the foregoing to the contrary,  the
indemnified  party will be  entitled  to select its own  counsel  and assume the
defense of any action  brought  against it if the  indemnifying  party  fails to
select counsel reasonably satisfactory to the indemnified party, the expenses of
such defense to be paid by the indemnifying  party. No indemnifying  party shall
consent to entry of any judgment or enter into any settlement  with respect to a
claim without the consent of the indemnified  party,  which consent shall not be
unreasonably  withheld,  or unless such  judgment or  settlement  includes as an
unconditional  term  thereof  the giving by the  claimant or  plaintiff  to such
indemnified party of a release from all liability with respect to such claim. No
indemnified  party  shall  consent  to entry of any  judgment  or enter into any
settlement  of any such  action,  the  defense  of which has been  assumed by an
indemnifying  party,  without  the  consent of such  indemnifying  party,  which
consent shall not be unreasonably withheld or delayed.

                                   Article VI

performs  those  services  identified  as  permissible  activity for Member-1 in
Section  4.1 of a certain  Asset  Purchase  Agreement  dated  December  2, 1997,
between the Buyer,  and others,  and White Rhino Drilling,  Inc. and Member-1 in

influence any employee of Buyer (or any of Buyers  affiliates) to terminate his
employment.   The  Member-2  agrees  that  if  either  the  length  of  time  or
geographical  area as set forth in this Section 4.1.2 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  4.1.2 are in addition to any other  obligations  that Member-2 may have
under the laws of any state  requiring  a  corporation  selling its assets (or a
member of such  corporation)  to limit its  activities  so that the goodwill and
business  relations  being  transferred  with such assets will not be materially
impaired.  Member-2 further agrees and acknowledges that Buyer does not have any

Party shall, prior to retaining such third party, give Buyer (or, as applicable,
Buyers  affiliate),  by delivery of appropriate  notice,  the opportunity  (the

offered by such third party,  Buyer (or, as applicable,  Buyers  affiliate) and
such First Call Party shall mutually agree on the specific terms, conditions and

see fit. In the event of a breach by a First Call Party of its obligations under
this  Section  4.5.2,  Buyer shall be entitled to recover any profits  lost as a
result of such breach (in  addition to all other  available  remedies).  For the

determined  by such  First Call  Party,  or (2) if the First Call Party does not
have control over the selection  process of the service  provider,  provided the
First Call Party may not grant  control to make such  selection to another party

          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 than 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

Article V Indemnification  V.1  Indemnification by the Seller and the MembersV.1
Indemnification by the Seller and the Members. In addition to any other remedies
available to Buyer under this Agreement,  or at law or in equity, the Seller and
each of the Members  shall,  jointly and severally,  indemnify,  defend and hold
harmless Buyer and its officers,  directors,  employees, agents and stockholders
(collectively,  the Buyer Indemnified Parties),  against and with respect to any
and all claims,  costs, damages,  losses,  expenses,  obligations,  liabilities,
recoveries,  suits,  causes  of action  and  deficiencies,  including  interest,
penalties and reasonable attorneys fees and expenses (collectively, the Damages)
that any of the Buyer  Indemnified  Parties shall incur or suffer,  which arise,
result  from or relate to (i) any  breach of, or failure by the Seller or any of
the Members 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 any of the
Members  under this  Agreement;  and (ii)  except to the extent the  Damages are
exacerbated  by Buyer or Key,  the  Retained  Liabilities.  The  indemnification
obligations of Seller and Member-1 and Member-3 under this Section 5.1 shall not
exceed  the  Purchase  Price;   provided,   however,  that  the  indemnification
obligations  of Seller and  Member-1  and  Member-3  under this  Section 5.1 for
Damages  incurred  or  suffered  which  arise  from or  relate  to the  Retained
Liabilities shall be unlimited in amount.

V.2  Indemnification  by BuyerV.2  Indemnification  by Buyer. In addition to any
other remedies available to the Seller and the Members under this Agreement,  or
at law or in equity, Buyer shall indemnify,  defend and hold harmless the Seller

agents  (collectively,  the Seller Indemnified Parties) against and with respect
to any and all Damages that any of the Seller Indemnified Parties shall incur or
suffer,  which arise,  result from or relate to (i) any breach of, or failure by
Buyer  to  perform,  any  of  its  representations,   warranties,  covenants  or
agreements in this Agreement or in any schedule,  certificate,  exhibit or other
instrument  furnished  or delivered to the Seller or any of the Members by or on
behalf of Buyer under this Agreement;  and (ii) except to the extent the Damages

V.3 Indemnification  ProcedureV.3 Indemnification Procedure. If any party hereto
discovers or otherwise becomes aware of an  indemnification  claim arising under
Section 5.1 or 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 amount of the claim is not increased by the timing of, or failure
to give such notice.  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 amount of the
claim is not increased by the timing of, or failure to give such notice. In case
any such action is brought against an indemnified  party, the indemnifying party
shall be entitled to participate in and to assume the defense  thereof,  jointly
with any other indemnifying party similarly notified,  to the extent that it may
wish, with counsel reasonably  satisfactory to such indemnified party, and after
such  notice  from  the  indemnifying  party  to such  indemnified  party of its
election so to assume the defense thereof,  the indemnifying  party shall not be
liable to such  indemnified  party for any legal or other expenses  subsequently
incurred  by the  latter in  connection  with the  defense  thereof  unless  the
indemnifying  party has failed to assume the defense of such claim and to employ
counsel  reasonably  satisfactory to such  indemnified  person.  An indemnifying
party who elects not to assume  the  defense of a claim  shall not be liable for
the fees and  expenses of more than one counsel in any single  jurisdiction  for
all parties indemnified by such indemnifying party with respect to such claim or
with respect to claims separate but similar or related in the same  jurisdiction
arising  out  of  the  same  general  allegations.  Notwithstanding  any  of the
foregoing to the contrary,  the indemnified party will be entitled to select its
own  counsel  and assume the  defense  of any action  brought  against it if the
indemnifying  party  fails to  select  counsel  reasonably  satisfactory  to the
indemnified  party,  the expenses of such defense to be paid by the indemnifying
party.  No  indemnifying  party shall  consent to entry of any judgment or enter
into  any  settlement  with  respect  to a  claim  without  the  consent  of the
indemnified party, which consent shall not be unreasonably  withheld,  or unless
such judgment or settlement includes as an unconditional term thereof the giving
by the  claimant or plaintiff  to such  indemnified  party of a release from all
liability  with respect to such claim.  No  indemnified  party shall  consent to
entry of any  judgment  or enter into any  settlement  of any such  action,  the
defense of which has been assumed by an indemnifying party,  without the consent
of such indemnifying party, which consent shall not be unreasonably  withheld or
delayed.

                                    ARTICLE 1

                                Purchase and Sale


1.1. Purchase and Sale of Sitton Shares.  Subject to the terms and conditions of
this  Agreement,  at the  Closing  (as  defined  in  Section  1.2  hereof),  the
Shareholders  agree to sell and convey to Key,  effective  as of 12:01  A.M.  on
January 1, 1998 (the "Effective  Time"),  free and clear of all Encumbrances (as

the Shareholders, all of the Sitton Shares. Subject to the provisions of Section
1.5 hereof, in consideration of the sale of the Sitton Shares,  Key shall pay to

Prepayment  Shortfall  (as defined in Section 1.5 hereof) and (b) $100,000  (the

6.1 hereof). In addition,  Key shall cause to be issued to the Shareholders,  in
accordance with Section 6.2 hereof,  100,000 shares (the "Key Energy Shares") of

agreed upon by the Shareholders, Key and the Parent .

1.3. Delivery of Sitton Certificates.  The Shareholders shall deliver to Key, on
the Closing Date, duly and validly issued  certificates  representing all of the
Sitton Shares, each of which certificates shall be duly endorsed in blank and in
good form for transfer or  accompanied  by stock powers duly  executed in blank,
sufficient  and in good form to  properly  transfer  such  shares to Key (or its
designee).


1.4. Distribution of Current Assets and Assumption of Liabilities.  On and after
the Closing Date,  all Current  Assets of Sitton at the Effective  Time (defined
below) shall be the sole property of the  Shareholders  and,  subject to Section
1.6 hereof,  Sitton shall have no rights thereto. On and after the Closing Date,
the  Shareholders  shall be solely  responsible for the Liabilities of Sitton at
the Effective Time (defined below). On the Closing Date, the Shareholders  shall
deliver to Key an executed copy of an assignment and  assumption  agreement in a
form  reasonably  satisfactory  to Key (the  "Assignment/Assumption  Agreement")
effecting (i) the transfer and assignment of the Current Assets of Sitton at the
Effective Time to the Shareholders and (ii) the assumption of the Liabilities of
Sitton at the  Effective  Time by the  Shareholders  . As used herein,  the term
"Current  Assets of  Sitton at the  Effective  Time"  means (i) all of  Sitton's
accounts  receivable  and all other  rights of Sitton to  payment  for  services
rendered by Sitton  before the  Effective  Time ("Prior  Accounts  Receivable"),
including,  without limitation,  those accounts receivable described in Schedule
2.1.8.4  hereto;  (ii) all cash  accounts of Sitton and all petty cash of Sitton
kept on hand for use in the  business in existence at the  Effective  Time;  and
(iii) all right,  title and  interest of Sitton in and to all  prepaid  rentals,
other prepaid  expenses (other than the  prepayments  referred to in Section 1.5
hereof),  bonds, deposits and financial assurance requirements and other current
assets  relating  to any of the  assets  of the  business  in  existence  at the
Effective Time. As used herein, the term "Liabilities of Sitton at the Effective
Time" means any and all liabilities  and obligations of Sitton,  incurred in the
ordinary  course of business  but not yet due and payable or the amount of which
is not yet known and all notes or other  indebtedness  or  obligations of Sitton
which has not been satisfied in full as of the Closing Date,  including  without
limitation  (i) the  litigation  referred to in Schedule  2.1.16  hereto and any
other litigation  brought or threatened  against Sitton arising out of events or
circumstances  occurring or existing before the Effective Time; (ii) any and all
taxes  payable  by Sitton for any period  before  the  Effective  Time (iii) the
amounts due under all indebtedness  referred to in Schedule  2.1.8.14 hereto and

(v) all  accounts  payable  and trade  payables  of Sitton in  existence  at the
Effective Time, including, without limitation, the accounts payable described in
Schedule 2.1.8.5 hereto (the "Prior  Payables").  Nothing in this Section 1.4 is
intended to limit the  representations  and warranties of or indemnifications by
the Shareholders contained herein or to expand the indemnification provisions of
7.1 or extend the period of time for which the  representations,  warranties and
covenants  of  the  parties  shall  survive  the  Closing  Date.  Key  shall  be
responsible for any and all liabilities and obligations  arising with respect to
the  ownership  and  operation of Sitton's  assets from and after the  Effective
Date,  except to the extent that such liabilities or obligations  arise out of a
breach  by  the  Shareholders  of  any  of  their  respective   representations,
warranties or covenants contained herein.

1.5. Required Payments.  Before the Effective Time, the Shareholders shall cause
Sitton to make prepayments  totaling at least $450,000 for the purchase of drill
bits to be delivered to Sitton after the Effective  Time.  The term  "Prepayment
Shortfall"  as used herein means the amount,  if any, by which such  prepayments
total less than $450,000.

1.6.  Retention  of  Receivables;  Payment of Payables;  Post-Closing  Adjusting
Payments. It is the intention and agreement of the parties that the Shareholders
will have full power and authority to collect the Prior Accounts Receivable from
and after the  Closing  Date,  and  Sitton  shall take no action  designated  to
interfere  with  the  collection  of  the  Prior  Accounts   Receivable  by  the
Shareholders.  However,  for a period of 90 days from the Closing  Date,  Sitton
shall have the right to deposit and use any  payments  received by Sitton or Key
(as  opposed  to  payments  received  by the  Shareholders)  on account of Prior
Accounts  Receivables  and the  right to pay any  Prior  Payables  and any other
unpaid  Liabilities of Sitton at the Effective  Time. At the end of such period,
Sitton shall deliver an accounting (the "Final  Accounting") of such payments to
the  Shareholders.  Key and the  Shareholders  shall  jointly  review  the Final
Accounting,  endeavor in good faith to resolve any  disagreements  regarding the
entries thereon and reach a final determination thereof within 120 days from the
Closing Date. If the parties are unable to reach a final determination  relative
to all  disagreements  regarding entries on the Final Accounting within such 120
day period they shall submit the unresolved issue or issues to a nationwide firm
of independent  certified public accountants selected by mutual agreement (or if
mutual  agreement  cannot be reached,  by lot), whose decision on the unresolved
issue or issues shall be binding on all parties hereto. The following  adjusting
payments shall be made:

(1)  If the total of all  proceeds  retained by Sitton  from the Prior  Accounts
     Receivable  plus the Retention  exceeds the total of all Prior Payables and
     other  Liabilities  of  Sitton at the  Effective  Time paid by Sitton , Key
     shall pay to the Shareholders the amount of such excess.

(2)  If the total of all  proceeds  retained by Sitton  from the Prior  Accounts
     Receivable  plus the Retention is less than the total of all Prior Payables
     and other  Liabilities of Sitton at the Effective Time paid by Sitton,  the
     Shareholders shall pay to Key the amount of such difference.


From and after the 90 day period referred to above, (i) all payments received by
Sitton on account of Prior Accounts  Receivables shall be promptly endorsed over
and delivered to the Shareholders in accordance with Section 8.4 hereof and (ii)
all unpaid  Liabilities  of Sitton at the Effective Time shall be subject to the
Shareholders' indemnification obligations in accordance with Section 7.1 hereof.

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

Shareholders  is a  resident  of Texas,  above the age of 18 years,  and has the
legal capacity and requisite  power and authority to enter into, and perform his

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 Sitton or (ii) any obligation,  indenture,  mortgage,
deed of trust,  lease,  contract or other agreement to which Sitton or either of
the  Shareholders is a party or by which Sitton or either of the Shareholders or
their respective properties are bound.

2.1.3.  Capitalization.  The  authorized  capitalization  of Sitton  consists of
1,000,000 shares of Sitton Common Stock, of which, as of the date hereof,  1,000

Shareholders.  On the date hereof, Sitton 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 Sitton Common Stock are validly issued,  fully paid and non-assessable
and are not subject to  preemptive  rights.  None of the  outstanding  shares of
Sitton Common Stock are subject to any voting trusts,  voting agreement or other
agreement or understanding with respect to the voting thereof,  nor is any proxy
in existence with respect thereto.

 
2.1.4.  Ownership of Sitton Shares.  Each Shareholder holds good and valid title
to  500  of  the  Sitton  Shares,  free  and  clear  of  all  Encumbrances.  The
Shareholders possess full authority and legal right to sell, transfer and assign
to Key the Sitton Shares,  free and clear of all Encumbrances.  Upon transfer to
Key by the  Shareholders  of the Sitton  Shares,  Key will own the Sitton Shares
free and  clear of all  Encumbrances.  There are no  claims  pending  or, to the
knowledge of either of the Shareholders, threatened, against Sitton or either of
the  Shareholders  that concern or affect title to either the Sitton Shares,  or
that seek to compel the issuance of capital stock or other securities of Sitton.

2.1.5. No  Subsidiaries.  There is no corporation,  partnership,  joint venture,
business  trust or other  legal  entity  in which  Sitton,  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.

Sheet,  or which have  thereafter  been  acquired  by it,  consist of items of a
quality usable and salable in the normal course of Sitton's business.

2.1.7.  Liabilities.  Except as disclosed on Schedule 2.1.7 hereto,  Sitton does
not have any liabilities or obligations, either accrued, absolute or contingent,
nor  do  either  of  the  Shareholders  have  any  knowledge  of  any  potential

Encumbrance of any nature whatsoever,  except (i)Encumbrances  reflected in the
9/30 Balance Sheet or in Schedule 2.1.8.1 hereto, and (ii)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 Sitton. All
leases  pursuant  to which  Sitton  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 Sitton  and in  respect  to which  Sitton has not taken
adequate steps to prevent a default from  occurring.  The buildings and premises
of Sitton that are used in its  business  are in good  operating  condition  and
repair,  subject  only to  ordinary  wear and  tear.  All rigs,  rig  equipment,

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

2.1.14.  Contracts. All contracts,  leases, plans or other arrangements to which
Sitton is a party, by which it is bound or to which it or its assets are subject
are in full force and effect,  and constitute  valid and binding  obligations of
Sitton and the other  parties  thereto.  Sitton is not, and to the  knowledge of
either of the Shareholders,  no other party to any such contract, lease, plan or
other  arrangement  is, in default  thereunder,  and no event has occurred which
(with or without  notice,  lapse of time,  or the  happening of any other event)
would  constitute  a default  thereunder.  No contract  has been entered into on
terms which could  reasonably  be expected to have an adverse  effect on Sitton.
Neither of the Shareholders has received any information  which would cause such
Shareholder to conclude that any customer of Sitton will (or is likely to) cease
doing business with Sitton (or its  successors) as a result of the  consummation
of the transactions contemplated hereby.

2.1.15.  Licenses and Permits.  Sitton  possesses  all permits,  authorizations,

administrative  powers of regulatory agencies having jurisdiction.  Sitton is in
compliance  in all  material  respects  with  the  terms  of each of the  Sitton
Permits.  No  Sitton  Permit  has  been,  or to the  knowledge  of either of the
Shareholders, is threatened to be, revoked, canceled, suspended or modified.

2.1.16.  Litigation.  Except as disclosed on Schedule 2.1.16 hereto, there is no
suit,  action,  or legal,  administrative,  arbitration,  or other proceeding or
governmental  investigation  pending  to  which  Sitton  is a party  or,  to the
knowledge of either of the  Shareholders,  might become a party or which affects
Sitton,  nor is any  change  in  the  zoning  or  building  ordinances  directly

and delivery of this Agreement have been authorized by all necessary  corporate,
shareholder  and other action on the part of the Parent,  and this  Agreement is

                                 Indemnification

7.1. Indemnification by Shareholders. On the terms and conditions and subject to
the  limitations  provided  in this  Article 7, each of the  Shareholders  shall
indemnify,  defend and hold harmless Sitton,  Key, the Parent,  their affiliates
and subsidiaries and their respective officers, directors, employees, agents and
stockholders  (collectively,  the "Key Indemnified  Parties"),  against and with
respect to any and all claims, costs, damages,  losses,  expenses,  obligations,
liabilities,  recoveries,  suits,  causes of action and deficiencies,  including
interest, penalties and attorneys' fees (collectively,  the "Damages") that such
indemnitees shall incur or suffer, which arise, result from or relate to (i) 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 by Key
or the Parent to the  Shareholders  under  this  Agreement  to the  extent  such
Damages  exceed  $100,000 in the aggregate or (ii) the  Liabilities of Sitton at
the  Effective  Time;  provided,  however,  that the  Shareholders  shall not be
required to so indemnify,  defend and hold harmless the Key Indemnified  Parties
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 either of the Shareholders under this Agreement
for which a Key Indemnified Party 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 8.1 hereof) of the specific  representation  or
warranty alleged to have been breached.

7.2.  Indemnification  by Key.  On the terms and  conditions  and subject to the
limitations  provided in this  Article 7, Key shall  indemnify,  defend and hold
harmless  each of the  Shareholders  against  and  with  respect  to any and all
Damages in excess of $100,000 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 Key shall not be required to so indemnify,
defend  and hold  harmless  the  Shareholders  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  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
specified  in Section 8.1  hereof) of the  specific  representation  or warranty
alleged to have been breached.


7.3.  Indemnification  Procedure.  If any party  hereto  discovers  or otherwise
becomes aware of an  indemnification  claim arising under Section 7.1 or Section
7.2 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 7, 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, 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.

                                 INDEMNIFICATION

4.1  Indemnification  by the Seller. In addition to any other remedies available
to  Buyer  under  this  Agreement,  or at law or in  equity,  the  Seller  shall
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 to perform, his 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 under this Agreement; and (ii) the Retained Liabilities.

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

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

4.4  Limitation on Damages.  Notwithstanding  anything in this  Agreement to the
contrary,  the Seller shall not be liable to the Buyer or any of its  affiliates
under this  Article IV, and Buyer  shall not be liable to the Seller  under this
Article IV, for cumulative costs of any Damages in excess of $800,000; provided,
however,  that such  limitation  on  liability  shall not  include  Damages  for
breaches of the representations and warranties contained in Section 2.1.10.

certificate,  schedule,  exhibit or other instrument  delivered pursuant to this

operations.  All leases  pursuant to which the Company leases (whether as lessee
or lessor)  any  substantial  amount of real or  personal  property  are in good

which could  reasonably  be expected to have an adverse  effect on the  Company.

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

have a  material  adverse  effect  on its  financial  condition,  properties  or
business.

2.2.2.   Agreement   Authorized  and  its  Effect  on  Other  Obligations.   The
consummation of the transactions  contemplated hereby have been duly and validly

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 Buyer will not conflict
with or  result  in a  violation  or  breach  of any term or  provision  of,  or

any brokerage commission, finder's fee or any similar payments.

                              Additional Agreements


3.1. Noncompetition.  Except as otherwise consented to or approved in writing by
Buyer,  Loveless  agrees  that for a period of 36 months  from the date  hereof,
Loveless  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 5% of any  security  of any class of any
corporation or other business entity (i) engage in competition with the business
or businesses  of well  servicing,  oil field  trucking and oil and gas contract
drilling  conducted by the Company,  Buyer or any affiliate of Buyer on the date
hereof,  or in any  service  business  the  services of which are  provided  and
marketed  by the  Company,  Buyer or any  affiliate  of Buyer on the date hereof
within a 150-mile radius of Abilene,  Texas;  (ii) request any present customers
or suppliers of the Company to curtail or cancel  their  business  with Buyer or
any affiliate of Buyer;  (iii) disclose to any person,  firm or corporation  any
trade, technical or technological secrets of the Company, Buyer or any affiliate
of Buyer or any details of their organization or business affairs or (iv) induce
or actively  attempt to  influence  any  employee of the  Company,  Buyer or any
affiliate of Buyer to terminate his employment. Except as otherwise consented to
or  approved in writing by Buyer,  Miller  agrees that for a period of 36 months
from the date hereof, Miller 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 5% of any  security of any
class of any corporation or other business entity (i) engage in competition with
the business of oil and gas contract drilling conducted by the Company, Buyer or
any affiliate of Buyer on the date hereof,  or any service business the services
of which are provided and  marketed by the  Company,  Buyer or any  affiliate of
Buyer on the date  hereof  within a  150-mile  radius of  Abilene,  Texas;  (ii)
request any present  customers  or suppliers of the Company to curtail or cancel
their  business  with Buyer or any  affiliate  of Buyer;  (iii)  disclose to any
person, firm or corporation any trade, technical or technological secrets of the
Company, Buyer or any affiliate of Buyer or any details of their organization or
business affairs or (iv) induce or actively attempt to influence any employee of
the  Company,  Buyer or any  affiliate  of Buyer to  terminate  his  employment;
however,  nothing in this Section 3.1 shall be construed to prevent  Miller from
being engaged in the oil and gas contract  drilling business as an employee of a
party or entity  that is not owned in whole or in part by Miller.  Loveless  and
Miller agree that if either the length of time or geographical area set forth in
the Section 3.1 is deemed too  restrictive in any court  proceeding,  such court
may  reduce  such  restrictions  to those  which it deems  reasonable  under the
circumstances.  The obligations expressed in this Section 3.1 are in addition to
any  other  obligations  that the  Shareholders  may have  under the laws of the
states in which they do  business  requiring  an  employee  of a  business  or a
shareholder  who sells his stock in a corporation  (including a disposition in a
merger) to limit his  activities so that the goodwill and business  relations of
his employer and of the  corporation  whose stock he has sold (and any successor
corporation) will not be materially impaired.  Loveless and Miller further agree
and  acknowledge  that the  Company,  Buyer and its  affiliates  do not have any
adequate remedy at law for the breach or threatened breach by either Loveless or
Miller of this covenant,  and agree that the Company,  Buyer or any affiliate of
Buyer may,  in  addition  to the other  remedies  which may be  available  to it
hereunder,  file a suit in equity to enjoin  Loveless or Miller 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.  Loveless and Miller  acknowledge  that the covenants set forth in this
Section  3.1  are  being   executed  and  delivered  by  such   Shareholder   in
consideration  of the covenants of Buyer  contained in this  Agreement,  and for
other good and valuable consideration,  receipt of which is hereby acknowledged.
In return for the noncompetition  covenants contained in this Section 3.1, Buyer
shall pay $255,000 to Jackie  Loveless and $45,000 to J. W. Miller,  in 36 equal
monthly  installments,  commencing March 1, 1998.  Notwithstanding any provision
contained in this Section 3.1, in the event that Buyer fails to employ Miller or
terminates  Miller without cause, the obligations of Miller contained in Section
3.1 of this  Agreement  shall  terminate  and be of no further  force and effect
however,  the  obligations of Buyer under this Section 3.1 will continue in full
force and effect.

3.2. Further  Assurances.  From time to time, as and when requested by any party
hereto,  any other  party  hereto  shall  execute  and  deliver,  or cause to be
executed and delivered,  such documents and instruments and shall take, or cause
to be taken,  such further or other  actions as may be  reasonably  necessary to
effectuate the transactions contemplated hereby.

                                    ARTICLE 4

                                 Indemnification

4.1.  Indemnification  by the  Shareholders.  In addition to any other  remedies
available  to Buyer under this  Agreement,  or at law or in equity,  each of the
Shareholders shall jointly and severally indemnify, defend and hold harmless the
Company,  Buyer and their affiliates and their respective  officers,  directors,
employees,  agents  and  stockholders  (collectively,   the  "Buyer  Indemnified
Parties"),  against  and with  respect to any and all  claims,  costs,  damages,
losses, expenses, obligations,  liabilities, recoveries, suits, causes of action
and deficiencies, including interest, penalties and reasonable fees and expenses
of attorneys,  consultants  and experts  (collectively,  the "Damages") that the
Buyer  Indemnified  Parties shall incur or suffer,  which arise,  result from or
relate to (i) any breach by any of the Shareholders of (or the failure of any of
the  Shareholders  to perform)  their  respective  representations,  warranties,
covenants  or  agreements  in this  Agreement or in any  schedule,  certificate,
exhibit  or  other  instrument  furnished  or  delivered  to Buyer by any of the
Shareholders  under this Agreement (ii) any  environmental  matters scheduled on
Schedules 2.1.17.1,  2.1.17.2,  2.1.17.3 or (iii) the Company's ownership and/or
operation of those properties  distributed to the Shareholders prior to the date
hereof  referred  to in Schedule  2.1.10  hereto  (the  "Indemnification").  The
Indemnification  provided by Mayfield and Miller shall be limited to $262,048.00
each.

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


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

                              Additional Agreements

3.1  Noncompetition.  Except as set forth below or as otherwise  consented to or
approved in writing by Buyer, the Seller and each of the Shareholders agree that

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 (a) engage in any  business in  competition  with the
business or  businesses  conducted by the Seller on or before the date hereof or
by Buyer (or Buyer=s  affiliates) on or after the date hereof, or in any service
business  the  services of which were  provided and marketed by the Seller on or
before the date hereof or by Buyer (or Buyer=s  affiliates) on or after the date
hereof in any state of the United  States,  or any foreign  country in which the
Seller  transacted  business  on or before the date hereof or in which Buyer (or
Buyer=s  affiliates)  transact business on or after the date hereof; (b) request
any present  customers or suppliers of the Seller or any  customers of Buyer (or
Buyer=s  affiliates)  to curtail or cancel their business with Buyer (or Buyer=s
affiliates);  (c)  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 (d) induce or
actively  attempt to influence any employee of Buyer (or Buyer=s  affiliates) to
terminate his employment.  The Seller and each of the Shareholders 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 Shareholders may have under the laws of any
state  requiring a  corporation  selling its assets (or a  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.  The Seller
and each of the  Shareholders  further agree and acknowledge that Buyer does not
have any  adequate  remedy  at law for the  breach or  threatened  breach by the
Seller or either of the Shareholders 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 either
of the Shareholders from such breach or threatened  breach. If any provisions of
this Section 3.1 are held to be invalid or against public policy,  the remaining
provisions  shall  not  be  affected  thereby.   The  Seller  and  each  of  the
Shareholders  acknowledge  that the  covenants set forth in this Section 3.1 are
being executed and delivered by such party in consideration of (i) the covenants
of Buyer  contained in this  Agreement,  (ii)  additional  consideration  in the
amount of  $300,000  payable  by Buyer on the date  hereof by wire  transfer  of
immediately  available  funds to those  parties,  in those  amounts and to those
accounts  specified in Schedule 3.1 hereto and (iii) for other good and valuable
consideration, the receipt and adequacy of which is hereby acknowledged.

Notwithstanding  anything to the contrary  stated in this paragraph 3.1, (i) the
conduct by the business entities listed in Schedule 3.1 hereto of the activities
set forth opposite such entities' names (the "Permitted  Businesses")  shall not
be a violation  of clause (a) of this Section 3.1 and (ii) the  solicitation  by
the business  entities listed in Schedule 3.1 hereto of any present  customer or
supplier  of the Seller or any  customers  of Buyer (or Buyer's  Affiliates)  in
connection  with the  conduct  of their  Permitted  Businesses,  but only  their
Permitted  Businesses  and not the  businesses  sold  hereunder,  shall not be a
violation of clause (b) of this paragraph 3.1. Seller and Shareholders  shall be
permitted to engage in those  businesses or activities set forth on Schedule 3.1
hereto and to solicit any customer of Seller or Buyer (or Buyer's affiliates) in
connection with such business or activities.

3.2 Hiring Employees.  Schedule 3.2 hereto is a complete and accurate listing of

subject  to such  Employees  meeting  Buyer=s  standard  employment  eligibility
requirements.  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.  The Seller
and each of the  Shareholders  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.

3.3  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.

                                   ARTICLE IV

                                 Indemnification

4.1 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 (the "Buyer Indemnified Parties"),  against and with respect to
any and all claims, costs, damages, losses, expenses, obligations,  liabilities,
recoveries,  suits,  causes  of action  and  deficiencies,  including  interest,
penalties  and  reasonable  attorneys=  fees  and  expenses  (collectively,  the
"Damages") that such indemnitee shall incur or suffer,  which arise, result from
or relate to (a) any material  breach of, or failure by the Seller 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 any of the
Shareholders under this Agreement; and (b) the Retained Liabilities.  Except for
Section  2.1.7,  for  purposes  of  this  Agreement,  a  breach  or  failure  of
performance shall not be material under this Agreement unless it has a financial
consequence of $10,000.00 or more to the non-breaching party; provided, however,
such threshold  shall not apply to damages  resulting to Buyer from the Retained
Liabilities.

4.2 Indemnification by Buyer. In addition to any other remedies available to the
Shareholders  under  this  Agreement,  or at  law  or  in  equity,  Buyer  shall
indemnify,  defend and hold  harmless  the Seller and its  officers,  directors,
employees, agents and stockholders and each of the Shareholders against and with
respect to any and all  Damages  that such  indemnitees  shall  incur or suffer,
which arise,  result from or relate to (a) any material breach of, or failure by
Buyer  to  perform,  any  of  its  representations,   warranties,  covenants  or
agreements in this Agreement or in any schedule,  certificate,  exhibit or other
instrument furnished or delivered to the Seller or any of the Shareholders by or
on behalf of Buyer under this Agreement and (b) the Assumed Liabilities.  Except
for  Section  2.1.7,  for  purposes  of this  Agreement,  a breach or failure of
performance shall not be material under this Agreement unless it has a financial
consequence of greater than $10,000.00 or more to the non-breaching party.

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

4.4 Limitation of Indemnity.  To the extent, if at all, ' 56-7-1 NMSA 1978 would
apply  to  render  any  of  the  indemnification   provisions  herein  void  and
unenforceable,  each such  provision  shall not  extend  to  liability,  claims,
damages,   losses  or  expenses,   including  attorney  fees,  relating  to  the
construction,   installation,  alteration,  modification,  repair,  maintenance,
servicing,   demolition,   excavation,  drilling,  reworking,  grading,  paving,
clearing,  site  preparation  or  development  of any  real  property  or of any
improvement on, above or under real property  arising out of (i) the preparation
or  approval of maps,  drawings,  opinions,  reports,  surveys,  change  orders,
designs,  or specification by the indemnitee,  or the agents or employees of the
indemnitee,  or  (ii)  the  giving  of or the  failure  to  give  directions  or
instructions  by the  indemnitee,  or the agents or employees of the indemnitee,
where such giving or failure to give  directions or  instructions is the primary
cause of bodily injury to persons or damage to property.

4.5  Limitation  of  Liability.  The maximum  liability  of the Buyer under this
Article IV and under the real estate  purchase and sale  agreement  described in
Section  3.5 hereto  shall be  limited  to  $10,000,000.  The  combined  maximum
liability of the Seller and the Shareholders under this Article IV and under the
real estate  purchase and sale agreement  described in Section 3.5 here to shall

                            STOCK PURCHASE AGREEMENT

THIS  STOCK  PURCHASE  AGREEMENT  (this  "Agreement")  is  entered  into  as  of
February 6,  1998,  among (i) Key Rocky Mountain,  Inc., a Delaware  corporation
("Buyer") and (ii) Updike  Brothers,  Inc. Employees= Stock Ownership Retirement

Dorothy R.  Updike  Trust,  Mary E.  Updike,  Ralph O. Updike and Daniel  Updike
(collectively, the "Shareholders").

                              W I T N E S S E T H:

WHEREAS,  Buyer is a corporation  duly organized and validly  existing under the
laws of the State of Delaware, with its principal executive offices at Two Tower
Center, 20th Floor, East Brunswick, New Jersey 08816;

WHEREAS,  Updike Brothers,  Inc. (the "Company") is a corporation duly organized
and validly existing under the laws of the State of Wyoming,  with its principal
executive offices at 2895 West Main Street, Newcastle, Wyoming 82701;

WHEREAS,  the  Shareholders  own 6,166 shares (the  "Company  Shares") of common
stock,  par value $10.00 per share, of the Company (the "Common  Stock"),  which
constitutes  all of the issued and  outstanding  shares of capital  stock of the
Company; and

WHEREAS, the Shareholders desire to sell to Buyer, and Buyer desires to purchase
from the Shareholders, all of the Company Shares.

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

                                    ARTICLE 1

                                PURCHASE AND SALE

1.1 Purchase and Sale of the Company Shares.

1.1.1 Purchase and Sale.  Subject to the terms and conditions of this Agreement,
on the date hereof, the Shareholders agree to sell and convey to Buyer, free and
clear of all  Encumbrances  (as defined in Section  2.1.8.1  hereof),  and Buyer
agrees to purchase and accept from the Shareholders,  all of the Company Shares.
In  consideration  of the sale of the  Company  Shares,  Buyer  shall pay to the
Shareholders a purchase price of $10,600,000 (the "Purchase Price") in cash, and
the Cash  Adjustment  Payment  (as defined in Section  1.2  hereof),  if any, in
accordance with Section 1.2 hereof.

1.1.2 Payment of Purchase Price.  The Purchase Price payable to the Shareholders
on the date hereof  shall be in the amounts  set forth on  Schedule 1.1.2.  Such
amounts are net of (i)  $530,000  payable to the Dillard  Group as  described in
Schedule 2.1.24,   and  (ii)  the  Cash   Adjustment   Payment  payable  to  the
Shareholders pursuant to Section 1.2.

1.1.3 Purchase  Price  Holdback.  A purchase  price holdback of $1,000,000  (the
"Purchase Price  Holdback")  will be deducted from the Cash  Adjustment  Payment
payable to the Shareholders pursuant to Section 1.2. The Purchase Price Holdback
shall be held in escrow  pursuant to the escrow  agreement dated the date hereof
(the "Escrow  Agreement") in the form of Exhibit A hereto and will be applied to
pay Environmental Assessments and Cleanup Costs (as defined in Section 3.4), Tax
Adjustments  (as  defined  in   Section 3.5),   and  to  cover   indemnification
obligations under Article IV of this Agreement.

1.1.4 Interest. Immediately before any portion of the Purchase Price Holdback is
distributed from the escrow account, maintained pursuant to the Escrow Agreement
the Buyer will pay into such escrow account an amount of cash, if any, necessary
to give the Shareholders receiving such distribution an annualized return on the
amount  distributed  equal to the  greater of (i) 8% or (ii) the  Federal  Funds
interest rate on the day before of the distribution plus 2-9/16%,  computed from
the date hereof through the date of the distribution.

1.1.5 Distribution of Purchase Price Holdback.  The Purchase Price Holdback will
be distributed to the Shareholders as follows:

1.1.5.1 Initial  Distribution.  At the time of the distribution of the assets of
the ESOP  contemplated by Section 1.6.2  of this Agreement,  the participants in
the ESOP  who  beneficially  owned an  interest  in the ESOP  entitling  them to
receive ten or fewer shares of Common Stock as of the Closing Date shall receive
a  distribution  from the Escrow Funds (as defined in the Escrow  Agreement)  an
amount equal to the unpaid  portion of the Purchase  Price forming a part of the
Purchase  Price  Holdback  allocable  to such  participants,  including  accrued
interest  through the date of the distribution as contemplated by Section 1.1.4.
The  Purchase  Price  Holdback  will  thereupon be reduced by the amount of such
distribution.

1.1.5.2 Final  Distribution.  On the third  anniversary of the date hereof,  the
Shareholders  will receive  from the Escrow  Account any portion of the Purchase
Price Holdback remaining after deduction of Environmental Assessment and Cleanup
Costs,  Tax  Adjustments  and all  amounts  necessary  to cover  indemnification
obligations  under  Article IV of this Agreement,  plus accrued interest through
such date based on their  percentage  interests  in the Company as  reflected on
Schedule 1.1.2.


<PAGE>

1.2 Cash Adjustment Payment.  Within 60 days after the date hereof,  Buyer shall
cause to be prepared and delivered to the  Shareholders a  consolidated  balance
sheet of the Company as of the date hereof (the  "Final  Balance  Sheet")  which
balance sheet will be prepared in accordance with generally accepted  accounting
principles,  consistently  applied in all respects.  Buyer and the  Shareholders
shall  jointly  review the Final  Balance  Sheet,  and endeavor in good faith to
resolve  all  disagreements  regarding  the  entries  thereon  and reach a final
determination thereof within 90 days from the date hereof. If the parties cannot
agree on the entries to be placed on the Final Balance  Sheet,  the dispute will
be  resolved  by an  independent  accounting  firm  mutually  agreed  to by  the
Shareholders  and Buyer  (such  agreement  not to be  unreasonably  withheld  or
delayed)  whose  resolution  shall be binding  on and  enforceable  against  the
parties  hereto.  Within  10 days of  reaching  such  final  determination,  the
following adjusting payments (which shall include interest at the rate of 8% per
annum accruing from the date hereof through the payment date) shall be made:

1.2.1 If the Final Net Current  Value of the  Company  (defined  below)  exceeds
$0.00,  Buyer shall pay to the  Shareholders  the amount of such difference (the
"Cash Adjustment Payment"), or

1.2.2 If the Final Net Current Value of the Company (defined below) is less than
$0.00, Shareholders shall pay to Buyer the amount of such difference.

1.2.3 In addition,  any capital  expenditures  made by Company since October 31,
1997, made with Buyer's prior  approval,  will be added to the Final Net Current
Value of the Company as set out in paragraph 1.2.1 or 1.2.2 above.  Buyer hereby
acknowledges approval of the capital expenditures listed on Schedule 1.2.3.

The term "Final Net Current Value of the Company"  means the dollar value of the
amount by which the "Total  Current  Assets" as  recorded  on the Final  Balance
Sheet exceeds the "Total Liabilities" as recorded on the Final Balance Sheet.

1.3 Closing.  Consummation  of the  transactions  contemplated by this Agreement
(the "Closing") shall take place at the offices of the Company,  2895 West Main,
Newcastle, Wyoming 82701, contemporaneously with the execution of this Agreement
by all of the parties hereto (the "Closing Date") unless another time,  place or
date is agreed to by the Shareholders and the Buyer.

duly  executed in blank  sufficient  and in good form to properly  transfer such
Company   Shares  to  Buyer;   (b)  David  W.  Updike  will  deliver  Buyer  (i)
an employment  agreement  dated the date  hereof in the form of  Exhibit B  (the
"Employment  Agreement")  and (ii) an  agreement  not to compete  dated the date
hereof  in  the  form  of  Exhibit C  (the  "Non-Compete  Agreement");   (c) the
Shareholders  and Buyer shall have delivered to one another all other documents,
instruments  and  agreements as required under this  Agreement;  (d) Buyer shall
deliver  to the  Shareholders  the cash  purchase  price  payable  at Closing as
provided  in  Section 1.1  by  checks  payable  to  the  order  of  each  of the
Shareholders; and (e) the Buyer and Shareholders will deliver to one another the

validly issued and are fully paid and  nonassessable  and are free of preemptive

against the  Shareholders  that are  parties  thereto in  accordance  with their
terms, except as the enforceability of this Agreement, the Escrow Agreement, the
Employment  Agreements and the  Noncompetition  Agreements may be limited by (a)
equitable  principles of general  applicability  or (b) bankruptcy,  insolvency,

1.6 Termination of ESOP.

1.6.1 Termination.  The Company, by action of its Board of Directors,  agrees to
take such action as is necessary or  appropriate  to terminate  the ESOP as of a
date before the Closing date.  After the effective  date of  termination  of the
ESOP,  the  ESOP  shall  be  "frozen"  pending  distribution  of its  assets  to
participants  and their  beneficiaries.  No persons who are not  participants or
beneficiaries as of the termination date shall be eligible to participate in the
ESOP or receive benefits  thereunder,  and no distributions shall be made by the
ESOP except normal  distributions in the ordinary course of business pursuant to
the terms and provisions of the ESOP document.

1.6.2 IRS Determination  Letters.  Within 120 days after the Closing Date, Buyer
agrees to file a submission to formally request a determination  letter from the
Internal  Revenue Service (the "IRS") to the effect that the ESOP is a qualified
plan under Section 401(a) of the Internal  Revenue Code of 1986, as amended (the
"Code")  upon its  termination  and that the  trust  used to fund the ESOP  (the
"Trust")  is  tax  exempt  under  Section   501(a)  of  the  Code.  As  soon  as
administratively  practicable following receipt of a favorable IRS determination
letter,  the  administrator  of the  Trust  shall  effect  distributions  of all
remaining  assets from the Trust and,  thereafter,  it shall be liquidated.  The
individual  trustees of the Trust as of the Closing  Date agree to serve in such
capacity  until  such  time as the  Trust  has been  liquidated  and its  assets
completely  distributed  unless the Buyer, in its discretion,  elects to appoint
any successor  trustee.  The  Shareholders  hereby agree that the Buyer does not
assume  any  liability  or  obligation  with  respect  to the ESOP or Trust that
results  from,  relates to, or arises out of any act or omission by the Company,
the  trustees or any other  person or entity  occurring on or before the Closing
Date.

                         REPRESENTATIONS AND WARRANTIES

2.1   Representations   and  Warranties  of  the   Shareholders.   Each  of  the
Shareholders,  jointly  and  severally,  represents  and  warrants  to  Buyer as

validly  existing and in good  standing  under the laws of the State of Wyoming,
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.

2.1.2  Agreements  Authorized and its Effect on Other  Obligations.  Each of the
Shareholders  has the legal capacity and requisite  power and authority to enter
into,  and perform  its  obligations  under this  Agreement  and the  Employment

Agreement,  the  Employment  Agreements and the  Non-Competition  Agreements are
valid  and  binding  obligations  of each of the  Shareholders  that are a party
thereto,  enforceable  against each of the Shareholders that are a party thereto
in accordance with their terms. The execution,  delivery and performance of this
Agreement, the Employment Agreements and the Non-Competition  Agreements by each
of the Shareholders that are a party thereto 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 the Company or (ii) any
obligation,  indenture,  mortgage,  deed of  trust,  lease,  contract  or  other
agreement to which the Company or any of the Shareholders is a party or by which
the Company or any of the Shareholders or their respective properties are bound.

2.1.3 Capitalization.  The authorized  capitalization of the Company consists of
100,000 shares of Common Stock,  of which,  as of the date hereof,  6,166 shares
are  issued  and  outstanding  and  held  beneficially  and  of  record  by  the
Shareholders.  On the date  hereof,  the Company  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 Common Stock are validly issued, fully paid and non-assessable and are
not subject to preemptive  rights (other than those preemptive  rights set forth
in Article VIII,  Section 3,  of the Company's  Bylaws,  which preemptive rights
have been waived by the Company). None of the outstanding shares of Common Stock
is  subject  to any  voting  trusts,  voting  agreement  or other  agreement  or
understanding with respect to the voting thereof,  nor is any proxy in existence
with respect thereto.

2.1.4  Ownership of the Company  Shares.  The  Shareholders  hold good and valid
title to the Company Shares set forth  opposite  their names on Schedule  1.1.2,
free and clear of all Encumbrances.  The Shareholders possess full authority and
legal right to sell,  transfer and assign the Company Shares to Buyer,  free and
clear of all  Encumbrances.  Upon transfer to Buyer by the  Shareholders  of the
Company  Shares,  Buyer  will  own the  Company  Shares  free  and  clear of all
Encumbrances.  There are no claims  pending or, to the  knowledge  of any of the
Shareholders,  threatened,  against the Company or any of the Shareholders  that
concern  or affect  title to the  Company  Shares,  or that  seek to compel  the
issuance of capital stock or other securities of the Company.

2.1.5  No  Subsidiaries.  Except  as set  forth on  Schedule 2.1.5,  there is no
corporation, partnership, joint venture, business trust or other legal entity in
which  the  Company,   either  directly  or  indirectly   through  one  or  more
intermediaries,  owns or holds beneficial or record ownership of the outstanding
voting securities.

2.1.6  Financial  Statements.  The Company has  delivered to Buyer copies of the
Company's  audited  balance  sheet as of  October 31,  1997,  a copy of which is
attached  hereto as Schedule  2.1.6 (the  "10/31  Balance  Sheet"),  and related
statements  of income,  with  appended  notes which are an integral part of such
statements,  (collectively,  the "Financial  Statements"),  as at and for the 12
months ended as of October 31,  1997 (the "Balance  Sheet Date").  The Financial
Statements are complete in all material  respects,  present fairly the financial
condition of the Company as of the dates and for the periods  indicated and have
been  prepared in  accordance  with  generally  accepted  accounting  principles
applied on a consistent  basis. The accounts  receivable  reflected in the 10/31
Balance Sheet, or which have been thereafter acquired by the Company,  have been
collected or are  collectible  at the aggregate  recorded  amounts  thereof less
applicable reserves, which reserves are adequate.

2.1.7  Liabilities.  Except as disclosed on Schedule 2.1.7.  hereto, the Company
does not have any  liabilities  or  obligations,  either  accrued,  absolute  or
contingent,  nor do any of the Shareholders  have any knowledge of any potential
liabilities  or  obligations  of the Company,  other than those (i) reflected or
reserved  against in the 10/31  Balance  Sheet or (ii)  incurred in the ordinary
course of  business  since the  Balance  Sheet  Date that  would not  materially
adversely affect the value and conduct of the business of the Company.

law), or (v)  obligates the Company to pay any benefits  solely as a result of a

contributed  to, or had an obligation to contribute to, any  multiemployer  plan
and has no withdrawal  liability  with respect to any  multiemployer  plan,  and

ERISA.  There are no  claims,  lawsuits  or  regulatory  actions  that have been
asserted, instituted or threatened against any Employee Plan by any fiduciary or

Closing Date the Purchase Price for the Company Shares held by the ESOP is equal

ESOP has determined  that the  transactions  contemplated  by this Agreement are
fair to the participants in the ESOP.

Company or any of the  Shareholders  an intention to conduct the same, and there

                                 INDEMNIFICATION

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

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

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

4.3  Limitation on Damages.  Notwithstanding  anything in this  Agreement to the
contrary, the Buyer Indemnified Parties shall be indemnified for Damages only to
the extent of the Purchase  Price  Holdback  after  deducting all  Environmental
Assessment and Cleanup Costs pursuant to  Section 3.4.  The aggregate  amount of
any Damages owed by the Buyer to the Shareholders shall not exceed $1,000,000 in
the aggregate.

4.4  Exclusive  Remedy.  From and  after the date  hereof,  the  payment  of (i)
Environmental Assessments and Cleanup Costs pursuant to Section 3.4 and (ii) the
costs  of  indemnification  under  Sections  4.1  and  4.2,  as  limited  by the
provisions of Section 4.4,  shall be the exclusive remedies for monetary damages
that may be asserted under this Agreement or in connection with the transactions
contemplated  herein.  Notwithstanding  any provision of the contrary  contained
herein, each of the parties to this Agreement hereby waives any right to recover
special, punitive or exemplary damages for any claim asserted against the other.
Noting in this Section 4.5 shall limit the  availability of equitable  remedies,
such as specific performance, to enforce the provisions of this Agreement.

II.1.2.  Agreements  Authorized  and  their  Effect  on Other  Obligations.  The
execution and delivery of this Agreement,  the Lease  Agreement,  the Employment
Agreement,  the Propane Purchase Agreement, the Noncompetition Agreement and the
Escrow  Agreement have been authorized by all necessary  corporate,  shareholder
and  other  action  on the  part  of  the  Seller,  Hy-Point,  Novosad  and  the
Shareholder,  and this Agreement, the Lease Agreement, the Employment Agreement,
the Propane  Purchase  Agreement,  the  Noncompetition  Agreement and the Escrow
Agreement  are the valid and binding  obligations  of the Seller and each of the
other  parties  thereto  other than the Buyer,  enforceable  (subject  to normal
equitable  principals)  against  each of such parties in  accordance  with their
respective  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,  the Lease Agreement,  the Employment Agreement, the Propane Purchase
Agreement,  the  Noncompetition  Agreement  and the  Escrow  Agreement,  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  (or  other
organizational  documents)  of the  Seller  or  Hy-Point,  (ii) any  obligation,
indenture,  mortgage, deed of trust, lease, contract or other agreement to which
the  Seller,  Hy-Point,  Novosad or the  Shareholder  is a party or by which the
Seller, Hy-Point,  Novosad 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,  Hy-Point,  Novosad  or  the  Shareholder  or any  of  their  respective
properties are subject.

II.1.3.  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 an adverse effect on the use of
the Assets by Buyer. Neither the Seller nor any of the Shareholders has received
any  information  that  would  cause any of such  parties to  conclude  that any
customer of the Seller will (or is likely to) cease  doing  business  with Buyer
(or  its  successors)  as a  result  of the  consummation  of  the  transactions
contemplated hereby. All of the Contracts are assignable (and are hereby validly
assigned) to Buyer without the consent of any other party thereto.

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).  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.  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 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.


II.1.5. 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 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  (and are hereby  assigned) to Buyer without the consent of
any regulatory agency. On and after the date hereof,  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 only to the  administrative
powers of  regulatory  agencies  having  jurisdiction  over the assigned  Seller
Permit.

II.1.6. Intellectual Property. Schedule 1.1(c) hereto sets forth a complete list
of all Intellectual  Property material to or necessary for the continued conduct
of the Business.  The Seller  Intellectual  Property is owned or licensed by the
Seller  free and clear of any  Encumbrances.  The Seller has not  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 Business did not,
infringe,  misappropriate  or conflict with the Intellectual  Property rights of
others.  Neither the Seller nor any of the  Shareholders 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.

II.1.7.  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
September 30, 1997 (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 that
are necessary for a fair  presentation of the 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 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.1.8.  Absence of Certain  Changes and Events.  Since the Balance  Sheet Date,
there has not been:

(a)  Financial  Change.  Any adverse  change in the Assets,  the Business or the
     financial condition, operations, liabilities or prospects of the Seller;

(b)  Property Damage. Any damage,  destruction,  or loss to any of the Assets or
     the Business (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,

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

II.1.9.  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 and the Seller Permits.


II.1.10.  Environmental  Matters.  None of the current or past operations of the
Business or any of the Assets is being or has been  conducted  or used in such a
manner as to constitute a violation of any  Environmental  Law (defined  below).
Neither the Seller nor any of the  Shareholders 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  Environmental  Law or regarding any claims
for remedial  obligations or contribution for removal costs or damages under any
Environmental Law. 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 any of the Shareholders,  threatened  relating to
the ownership, use, maintenance or operation of the Assets or the conduct of the
Business,  nor, to the  knowledge of the Seller or any of the  Shareholders,  is
there any basis for any of the  foregoing.  Buyer is not  required to obtain any
permits, licenses or similar authorizations pursuant to any Environmental Law 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 the Seller or any of
the  Shareholders,  the Assets include all  environmental  and pollution control
equipment  necessary  for  compliance  with  applicable  Environmental  Law.  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  situated  on or under any of the  Seller's  properties,  whether  owned or
leased,  or  incorporated  into any of the Assets.  There are no, and there have
never been any,  underground  storage tanks (as defined under Environmental Law)
located under any of the Seller's properties, whether owned or leased. There are
no environmental conditions or circumstances,  including the presence or release
of any Hazardous  Materials,  on any property  presently or previously  owned or
leased by the Seller, or on any property on which Hazardous  Materials generated
by the  Seller's  operations  or the use of the Assets were  disposed  of, which
would result in an adverse  change in the Business or business  prospects of the
Seller.  The term  "Environmental  Law" means any and all laws,  rules,  orders,
regulations, statutes, ordinances, codes, decrees, and other legally enforceable
requirements (including,  without limitation,  common law) of the United states,
or any state,  regional,  city, local, municipal or other governmental authority
or   quasi-governmental   authority,   regulating,   relating  to,  or  imposing
environmental  standards of conduct concerning  protection of the environment or
human health,  or employee health and safety as from time to time has been or is
now  in   effect.   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 Environmental Law.

II.1.11. 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 an adverse
effect on the Assets or the Business.  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 any of the Shareholders,  any disputes threatened
by current or former employees of any of the Seller.

II.1.12.   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 Shareholders,  threatened,  nor has any governmental entity indicated
to the Seller or any of the Shareholders an intention to conduct the same. 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 would adversely affect the Assets or
the Buyer's future conduct of the Business.

II.1.13.  Absence  of  Certain  Business  Practices.  Neither  the  Seller,  the
Shareholders,  nor any  officer,  employee or agent of the Seller,  or any other
person acting on behalf of the Seller or any of the Shareholders,  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  conduct of the
Business  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 an adverse effect on the profitable conduct of the Business
or the  profitable use of the Assets,  or if not continued in the future,  might
adversely affect the profitable conduct of the Business or the profitable use of
the Assets.

II.1.14. 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.1.15. Untrue Statements.  This Agreement and all other agreements executed by
the Seller or any of the  Shareholders  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
contracts,  documents concerning all litigation and administrative  proceedings,
licenses,  permits,  insurance policies,  lists of suppliers and customers,  and
records  relating   principally  to  the  Business  and  the  Assets,  and  such
information covers all commitments and liabilities of Buyer relating principally
to the Business and the Assets.

II.1.16.  Finder's Fee. Except as described on Schedule 2.1.16, all negotiations
relative to this Agreement and the  transactions  contemplated  hereby have been
carried on by the Seller and 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.

II.2  Representations  and Warranties of Buyer. Buyer represents and warrants to

consummation of the transactions  contemplated hereby, the Lease Agreement,  the

                                   Article IV

                                 Indemnification

IV.1  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 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 any of the  Shareholders  under this Agreement;  and (ii)
the Retained Liabilities.

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

  
IV.3  Indemnification  Procedure.  If any party  hereto  discovers  or otherwise
becomes  aware of an  indemnification  claim arising under Section 4.1 or 4.2 of
this  Agreement,  such  indemnified  party  shall  give  written  notice  to the
indemnifying  party,  specifying  such claim,  and may  thereafter  exercise any
remedies available to such party under this Agreement;  provided,  however, that
the failure of any indemnified party to give notice as provided herein shall not
relieve the indemnifying party of any obligations  hereunder,  to the extent the
indemnifying party is not materially prejudiced thereby. Further, promptly after
receipt by an indemnified  party hereunder of written notice of the commencement
of any action or  proceeding  with respect to which a claim for  indemnification
may be made pursuant to this Article 4, such indemnified party shall, if a claim
in respect thereof is to be made against any  indemnifying  party,  give written
notice to the latter of the commencement of such action; provided, however, that
the failure of any indemnified party to give notice as provided herein shall not
relieve the indemnifying party of any obligations  hereunder,  to the extent the
indemnifying party is not materially prejudiced thereby. In case any such action
is  brought  against an  indemnified  party,  the  indemnifying  party  shall be
entitled to participate in and to assume the defense  thereof,  jointly with any
other  indemnifying  party similarly  notified,  to the extent that it may wish,
with counsel  reasonably  satisfactory to such indemnified party, and after such
notice from the indemnifying  party to such indemnified party of its election so
to assume the defense  thereof,  the  indemnifying  party shall not be liable to
such indemnified party for any legal or other expenses  subsequently incurred by
the latter in connection with the defense thereof unless the indemnifying  party
has failed to assume the defense of such claim and to employ counsel  reasonably
satisfactory to such indemnified person. An indemnifying party who elects not to
assume the defense of a claim  shall not be liable for the fees and  expenses of
more than one counsel in any single  jurisdiction for all parties indemnified by
such  indemnifying  party with  respect to such claim or with  respect to claims
separate but similar or related in the same jurisdiction arising out of the same
general allegations.  Notwithstanding any of the foregoing to the contrary,  the
indemnified  party will be  entitled  to select its own  counsel  and assume the
defense of any action  brought  against it if the  indemnifying  party  fails to
select counsel reasonably satisfactory to the indemnified party, the expenses of
such defense to be paid by the indemnifying  party. No indemnifying  party shall
consent to entry of any judgment or enter into any settlement  with respect to a
claim without the consent of the indemnified  party,  which consent shall not be
unreasonably  withheld,  or unless such  judgment or  settlement  includes as an
unconditional  term  thereof  the giving by the  claimant or  plaintiff  to such
indemnified party of a release from all liability with respect to such claim. No
indemnified  party  shall  consent  to entry of any  judgment  or enter into any
settlement  of any such  action,  the  defense  of which has been  assumed by an
indemnifying  party,  without  the  consent of such  indemnifying  party,  which
consent shall not be unreasonably withheld or delayed.

IV.4  Limitation on Damages.  Notwithstanding  anything in this Agreement to the
contrary,  neither the Seller nor any of the Shareholders shall be liable to the
Buyer or any of its affiliates,  and Buyer shall not be liable to the Seller and
the  Shareholders,  for cumulative costs of any Damages in excess of $1,900,000;
provided,  however,  that such limitation on liability shall not include Damages
for breaches of the representations and warranties contained in Section 2.1.10.

                                  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.

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:

after the date hereof (the "Shelf Filing  Deadline"),  cause to be filed a shelf
registration statement pursuant to Rule 415 under the Securities Act (the "Shelf

best efforts to keep such Shelf Registration Statement  continuously  effective,
supplemented and amended as required by the provisions of Section 4(b) hereof to
the extent  necessary to ensure that it is available  for resales by the Holders
of Transfer Restricted Securities entitled to the benefit of this Agreement, and
to  ensure  that it  conforms  with  the  requirements  of this  Agreement,  the
Securities  Act and the policies,  rules and  regulations  of the  Commission as
announced  from time to time,  for a period of at least two years  following the

Restricted  Securities  in any Shelf  Registration  Statement  pursuant  to this
Agreement  unless and until such  Holder  furnishes  to the  Company in writing,
within 10 Business Days after receipt of a request therefor, such information as
the  Company  may  reasonably  request  for use in  connection  with such  Shelf
Registration  Statement or Prospectus or preliminary Prospectus included therein
and in any  application  to be filed with or under  state  securities  laws.  No
Holder of Transfer Restricted Securities shall be entitled to Liquidated Damages

all such  reasonably  requested  information.  Each Holder as to which any Shelf
Registration  Statement  is being  effected  agrees to furnish  promptly  to the
Company  all  information  required  to  be  disclosed  in  order  to  make  the
information  previously  furnished to the Company by such Holder not  materially

3. Liquidated Damages.

(a) If the Shelf  Registration  Statement  required by this Agreement (i) is not
filed with the  Commission  on or before the date  specified  for such filing in
Section 2(a)(i) hereof,  (ii) has not been declared  effective by the Commission
on or before the date  specified  for such  effectiveness  in  Section  2(a)(ii)
hereof (the "Effectiveness  Target Date"), or (iii) subject to the provisions of
Section  4(b)(i) below,  is filed and declared  effective but, during the period
specified in Section 2(a)(ii) hereof,  shall thereafter cease to be effective or
fail to be usable for its intended  purpose  without being  succeeded  within 15
Business Days by a post-effective  amendment to such Registration Statement that
cures such failure and that is itself immediately  declared effective (each such
event  referred  to in  foregoing  clauses (i) through  (iii),  a  "Registration
Default"),  the Company  hereby agrees to pay  liquidated  damages  ("Liquidated
Damages") to (A) each holder of Notes with respect to any period  during which a
Registration  Default shall have occurred and be continuing,  in an amount equal
to three  quarters  of one  percent  (75 basis  points)  per  annum  per  $1,000
principal amount of Notes held by such Holder;  and (B) each Holder of shares of
Common Stock issued upon conversion of Notes with respect to any period in which
a Registration Default shall have occurred and be continuing, in an amount equal
to $.29 per annum per share of Common Stock,  subject to adjustment in the event
of stock splits, stock recombinations, stock dividends and the like.

(b) All accrued  Liquidated  Damages shall be paid to holders of Notes or Record
Holders  by the  Company  on each  Damages  Payment  Date by  wire  transfer  of
immediately available funds or by federal funds check. Following the cure of all
Registration  Defaults relating to any particular Note or share of Common Stock,
the accrual of  Liquidated  Damages with respect to such Note or share of Common
Stock will cease.

4. Registration Procedures.

(a) In  connection  with the Shelf  Registration  Statement,  the Company  shall
comply  with all the  provisions  of  Section  4(b) below and shall use its best
efforts  to  effect  such  registration  to  permit  the  sale  of the  Transfer
Restricted  Securities  being sold in  accordance  with the  intended  method or
methods of  distribution  thereof,  and  pursuant  thereto,  the Company will as
expeditiously  as  possible  prepare  and  file  with  the  Commission  a  Shelf
Registration  Statement  relating to the  registration on any  appropriate  form
under the Securities Act.

(b) In  connection  with the Shelf  Registration  Statement  and any  Prospectus
required by this  Agreement to permit the sale or resale of Transfer  Restricted
Securities, the Company shall:

(i) Use its  best  efforts  to keep  such  Registration  Statement  continuously
effective;  upon  the  occurrence  of  any  event  that  would  cause  any  such
Registration  Statement  or the  Prospectus  contained  therein (A) to contain a
material  misstatement  or  omission or (B) to not be  effective  and usable for
resale of  Transfer  Restricted  Securities  during the period  required by this
Agreement,  the Company  shall file  promptly an  appropriate  amendment to such
Registration  Statement,  in  the  case  of  clause  (A),  correcting  any  such
misstatement or omission,  and, in the case of either clause (A) or (B), use its
reasonable  best efforts to cause such  amendment to be declared  effective  and
such  Registration  Statement  and the related  Prospectus  to become usable for
their intended purposes as soon as practicable  thereafter.  Notwithstanding the
foregoing,  if the Board of  Directors of the Company  determines  in good faith
that it is in the best interests of the Company not to disclose the existence of
or facts  surrounding  any proposed or pending  material  corporate  transaction
involving the Company, the Company may allow the Shelf Registration Statement to
fail to be  effective  and  usable as a result of such  nondisclosure  for (1) a
period not to exceed 30 days in any three month period or (2) two periods not to
exceed an aggregate of 60 days in any twelve month period.

(ii) Prepare and file with the Commission  such  amendments  and  post-effective
amendments  to the  Registration  Statement  as may be  necessary  to  keep  the
Registration  Statement  effective for the period set forth in Section  2(a)(ii)
hereof or such shorter  period as will  terminate  when all Transfer  Restricted
Securities  covered by such  Registration  Statement  have been sold;  cause the
Prospectus to be supplemented by any required Prospectus  supplement,  and as so
supplemented  to be filed pursuant to Rule 424 under the Securities  Act, and to
comply  fully  with the  applicable  provisions  of Rules 424 and 430A under the
Securities  Act in a  timely  manner;  and  comply  with the  provisions  of the
Securities Act with respect to the disposition of all securities covered by such
Registration  Statement  during the  applicable  period in  accordance  with the
intended  method or methods of  distribution by the sellers thereof set forth in
such Registration Statement or supplement to the Prospectus.

(iii) Advise the  underwriter(s),  if any, and selling holders  promptly (but in
any event  within two  Business  Days) and, if  requested  by such  Persons,  to
confirm  such  advice in  writing,  (A) when the  Prospectus  or any  Prospectus
supplement or post-effective  amendment has been filed, and, with respect to any
Registration  Statement or any post-effective  amendment thereto,  when the same
has become effective, (B) of any request by the Commission for amendments to the
Registration  Statement or amendments or  supplements  to the  Prospectus or for
additional  information  relating thereto, (C) of the issuance by the Commission
of any stop order suspending the  effectiveness  of the  Registration  Statement
under the Securities Act or of the suspension by any state securities commission
of the qualification of the Transfer Restricted  Securities for offering or sale
in  any  jurisdiction,  or  the  initiation  of any  proceeding  for  any of the
preceding  purposes,  (D) of the  existence of any fact or the  happening of any
event  that makes any  statement  of a  material  fact made in the  Registration
Statement, the Prospectus,  any amendment or supplement thereto, or any document
incorporated  by reference  therein  untrue,  or that requires the making of any
additions to or changes in the Registration Statement or the Prospectus in order
to make the  statements  therein not  misleading.  If at any time the Commission
shall issue any stop order  suspending  the  effectiveness  of the  Registration
Statement,  or any state  securities  commission or other  regulatory  authority
shall  issue  an  order   suspending   the   qualification   or  exemption  from
qualification  of the Transfer  Restricted  Securities under state securities or
Blue Sky laws, the Company shall use its  reasonable  best efforts to obtain the
withdrawal or lifting of such order at the earliest possible time.

(iv) Furnish to each of the selling holders and each of the  underwriter(s),  if
any, before filing with the Commission,  copies of any Registration Statement or
any  Prospectus  included  therein or any  amendments or supplements to any such
Registration  Statement or Prospectus  (including,  upon request in writing, all
documents   incorporated   by  reference   after  the  initial  filing  of  such
Registration  Statement),  which documents will be subject to the review of such
holders and  underwriter(s),  if any,  for a period of at least  three  Business
Days,  and the  Company  will  not  file  any  such  Registration  Statement  or
Prospectus or any amendment or supplement to any such Registration  Statement or
Prospectus  (including all such documents  incorporated by reference) to which a
selling holder of Transfer  Restricted  Securities  covered by such Registration
Statement or the  underwriter(s),  if any, shall reasonably  object within three
Business Days after the receipt  thereof.  A selling holder or  underwriter,  if
any,  shall  be  deemed  to have  reasonably  objected  to such  filing  if such
Registration Statement,  amendment,  Prospectus or supplement, as applicable, as
proposed to be filed, contains a material misstatement or omission.

(v) Promptly  before the filing of any document  that is to be  incorporated  by
reference into a Registration  Statement or Prospectus  after the initial filing
of such  Registration  Statement,  (A)  provide  copies of such  document to the
selling  Holders  and to the  underwriter(s),  if any,  (B) make  the  Company's
representatives  available for  discussion of such document and other  customary
due diligence matters,  and (C) include such information in such document before
the filing thereof as such selling Holders or underwriter(s), if any, reasonably
may request.

(vi) Make available at reasonable  times for inspection by the selling  Holders,
any underwriter  participating in any distribution pursuant to such Registration
Statement,  and any attorney or accountant  retained by such selling  Holders or
any of the underwriter(s),  all financial and other records, pertinent corporate
documents  and  properties  of the  Company  and cause the  Company's  officers,
directors, managers and employees to supply all information reasonably requested
by any such Holder, underwriter,  attorney or accountant in connection with such
Registration Statement after the filing thereof and before its effectiveness.

(vii)  If  requested  by any  selling  Holders  or the  underwriter(s),  if any,
promptly incorporate in any Registration Statement or Prospectus,  pursuant to a
supplement or  post-effective  amendment if necessary,  such information as such
selling  Holders and  underwriter(s),  if any,  may  reasonably  request to have
included therein,  including,  without limitation,  information  relating to the
"Plan of Distribution" of the Transfer Restricted  Securities,  information with
respect to the principal amount of Transfer Restricted  Securities being sold to
such underwriter(s),  the purchase price being paid therefor and any other terms
of the  offering  of the  Transfer  Restricted  Securities  to be  sold  in such
offering;  and  make all  required  filings  of such  Prospectus  supplement  or
post-effective amendment as soon as practicable after the Company is notified of
the matters to be incorporated in such Prospectus  supplement or  post-effective
amendment.

(viii)  Furnish to each selling Holder and each of the  underwriter(s),  if any,
without charge, at least one copy of the Registration  Statement, as first filed
with the Commission,  and of each amendment thereto,  including, if requested in
writing,  all documents  incorporated by reference  therein and, if requested in
writing, all exhibits (including exhibits incorporated therein by reference).

(ix)  Deliver to each  selling  Holder and each of the  underwriter(s),  if any,
without charge,  as many copies of the Prospectus  (including  each  preliminary
prospectus) and any amendment or supplement  thereto as such Persons  reasonably
may request;  the Company  hereby  consents to the use of the Prospectus and any
amendment or supplement  thereto by each of the selling  Holders and each of the
underwriter(s),  if any, in  connection  with the  offering  and the sale of the
Transfer  Restricted  Securities  covered by the  Prospectus or any amendment or
supplement thereto.

(x) Whether or not an underwriting  agreement is entered into and whether or not
the  registration is an Underwritten  Registration,  the Company shall: (A) upon
request,  furnish to each selling Holder and each  underwriter,  if any, in such
substance and scope as they may reasonably  request and as are customarily  made
by issuers to underwriters in primary underwritten  offerings,  upon the date of
effectiveness of the Shelf Registration Statement: (1) a certificate,  dated the
date of effectiveness  of the Shelf  Registration  Statement,  signed by (y) the
President and (z) the Chief Financial Officer of the Company  confirming,  as of
the date thereof,  the matters set forth in Section 1 of the Purchase  Agreement
and such other matters as such parties may reasonably  request;  (2) an opinion,
dated the date of effectiveness of the Shelf Registration  Statement, of counsel
for the Company  covering  the matters set forth in Section 7(c) of the Purchase
Agreement;  and  (3)  customary  comfort  letters,  dated  as  of  the  date  of
effectiveness of the Shelf Registration Statement from the Company's independent
accountants,  in the customary form and covering matters of the type customarily
covered  in  comfort   letters  by   underwriters  in  connection  with  primary
underwritten offerings; (B) set forth in full or incorporate by reference in the
underwriting agreement, if any, the indemnification provisions and procedures of
Section 6 hereof with respect to all parties to be indemnified  pursuant to said
Section;  and (C)  deliver  such  other  documents  and  certificates  as may be
reasonably  requested  by such  parties to evidence  compliance  with clause (A)
above and with any customary conditions contained in the underwriting  agreement
or other agreement  entered into by the selling Holders  pursuant to this clause
(x).

(xi) Before any public  offering of Transfer  Restricted  Securities,  cooperate
with the selling  Holders,  the  underwriter(s),  if any,  and their  respective
counsel in connection with the  registration  and  qualification of the Transfer
Restricted   Securities   under  the   securities  or  Blue  Sky  laws  of  such
jurisdictions as the selling Holders or  underwriter(s),  if any, may reasonably
request and do any and all other acts or things necessary or advisable to enable
the  disposition in such  jurisdictions  of the Transfer  Restricted  Securities
covered by the Shelf Registration Statement; provided, however, that the Company
shall not be required to register or qualify as a foreign  corporation  where it
is not now so  qualified  or to take any  action  that  would  subject it to the
service of process, in any jurisdiction where it is not now so subject.

(xii)  Cooperate  with the selling  Holders and the  underwriter(s),  if any, to
facilitate  the timely  preparation  and delivery of  certificates  representing
Transfer  Restricted  Securities to be sold; and enable such Transfer Restricted
Securities  to be in such  denominations  and  registered  in such  names as the
Holders or the  underwriter(s),  if any, may request at least two Business  Days
before any sale of Transfer Restricted Securities made by such underwriter(s).

(xiii)  Use its  reasonable  best  efforts  to  cause  the  Transfer  Restricted
Securities  covered  by the  Registration  Statement  to be  registered  with or
approved  by such other U.S.  governmental  agencies  or  authorities  as may be
necessary to enable the seller or sellers thereof or the underwriter(s), if any,
to consummate the disposition of such Transfer Restricted Securities.

(xiv) Subject to Section  4(b)(i) above,  if any fact or event  contemplated  by
Section 4(b)(iii)(D) above shall exist or have occurred, prepare a supplement or
post-effective  amendment to the Registration Statement or related Prospectus or
any  document  incorporated  therein  by  reference  or file any other  required
document  so  that,  as  thereafter  delivered  to the  purchasers  of  Transfer
Restricted Securities,  the Prospectus will not contain an untrue statement of a
material  fact or  omit  to  state  any  material  fact  necessary  to make  the
statements therein not misleading.

(xv)  Cooperate and assist in any filings  required to be made with the NASD and
in the performance of any due diligence investigation by any underwriter that is
required to be  retained in  accordance  with the rules and  regulations  of the
NASD.

(xvi)  Otherwise use its  reasonable  best efforts to comply with all applicable
rules and  regulations of the  Commission,  and make generally  available to its
security  holders,  as soon as practicable,  a consolidated  earnings  statement
meeting  the  requirements  of Rule  158  (which  need not be  audited)  for the
twelve-month  period (A)  commencing  at the end of any fiscal  quarter in which
Transfer  Restricted  Securities  are  sold  to  underwriters  in a firm or best

offering,  beginning with the first month of the Company's  first fiscal quarter
commencing after the effective date of the Registration Statement.

(xvii)  Cause the  Indenture  to be  qualified  under the TIA not later than the
effective date of the first  Registration  Statement required by this Agreement,
and,  in  connection  therewith,  cooperate  with the trustee and the holders of
Notes to effect  such  changes  to the  Indenture  as may be  required  for such
Indenture  to be so  qualified  in  accordance  with the  terms of the TIA;  and
execute and use its reasonable  best efforts to cause the trustee  thereunder to
execute all documents  that may be required to effect such changes and all other
forms and  documents  required  to be filed with the  Commission  to enable such
Indenture to be so qualified in a timely manner.

(xviii) Cause all Transfer  Restricted  Securities  covered by the  Registration
Statement to be listed on each securities  exchange on which similar  securities
issued by the Company are then listed.

(xix) Provide  promptly to each Holder upon written  request each document filed
with the Commission pursuant to the requirements of Section 13 and Section 15 of
the Exchange Act after the Effective Date of the Registration Statement.

(c) Each Holder agrees by  acquisition of a Transfer  Restricted  Security that,
upon receipt of any notice from the Company of the  existence of any fact of the
kind  described  in Section  4(b)(iii)(D)  hereof,  such Holder  will  forthwith
discontinue  disposition  of  Transfer  Restricted  Securities  pursuant  to the
applicable  Registration  Statement until such Holder's receipt of the copies of
the supplemented or amended Prospectus contemplated by Section 4(b)(xiv) hereof,
or until it is advised in writing (the  "Advice") by the Company that the use of
the  Prospectus  may be resumed,  and has received  copies of any  additional or
supplemental filings that are incorporated by reference in the Prospectus. If so
directed  by the  Company,  each  Holder  will  deliver to the  Company  (at the
Company's  expense) all copies,  other than  permanent  file copies then in such
Holder's  possession,  of  the  Prospectus  covering  such  Transfer  Restricted

excluding (a) fees and expenses of counsel to the underwriter(s),  if any (other
than  fees  and  expenses  set  forth  in  clauses  (i)  and  (ii)  above),  (b)
underwriting  discounts and  commissions and (c) transfer fees and taxes if any,
relating to the sale and  disposition  of Transfer  Restricted  Securities  by a
selling  Holder.  The Company  will,  in any event,  bear its internal  expenses
(including,  without  limitation,  all salaries and expenses of its officers and
employees  performing  legal or accounting  duties),  the expenses of any annual
audit  and the fees and  expenses  of any  Person,  including  special  experts,
retained by the Company.

(b) In connection with any  Registration  Statement  required by this Agreement,
the Company will  reimburse the Initial  Purchasers  and the Holders of Transfer
Restricted  Securities  being  registered  pursuant  to the  Shelf  Registration

than one  counsel  chosen by the Holders of a majority  in  principal  amount of
Debentures  and in  number of shares of  Common  Stock  issued  upon  conversion

6. Indemnification and Contribution.

(a) The Company  agrees to indemnify and hold  harmless:  (i) each Holder;  (ii)
each  person,  if any,  who  controls  (within  the meaning of Section 15 of the
Securities Act or Section 20 of the Exchange Act) any Holder (any of the persons
referred to in this clause (ii) being  referred to as a  "controlling  person");
and   (iii)   the   respective   officers,   directors,   partners,   employees,
representatives  and agents of any Holder or any controlling  person (any person
referred to in clause (i),  (ii), or (iii)  hereinafter  being referred to as an
"Indemnified Holder"), against any losses, claims, damages or liabilities, joint
or  several,  to which such  Indemnified  Holder may  become  subject  under the
Securities  Act,  the  Exchange  Act or  otherwise,  insofar as any such losses,
claims,  damages or liabilities (or actions in respect  thereof) arise out of or
are based upon:  (i) any untrue  statement  or alleged  untrue  statement of any
material fact contained in (A) any  Registration  Statement or Prospectus or any
amendment or supplement thereto or (B) any application or other document, or any
amendment or supplement  thereto,  executed by the Company or based upon written
information  furnished by or on behalf of the Company filed in any  jurisdiction
in order to qualify the Notes and the Common Stock issued upon conversion of the
Notes under the state securities or "Blue Sky" laws or filed with the Commission
or any securities association or securities exchange (each an "Application"); or
(ii) the omission or alleged omission to state, in such  Registration  Statement
or Prospectus or any amendment or supplement thereto,  or in any Application,  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,  and will reimburse,  as incurred,  each Indemnified  Holder for any
legal or other  expenses  reasonably  incurred  by such  Indemnified  Holder  or
controlling  person in  connection  with  investigating,  defending  against  or
appearing as a  third-party  witness in  connection  with any such loss,  claim,
damage, liability or action;  provided,  however, the Company will not be liable
in any such case to the extent that any such loss,  claim,  damage, or liability
is  finally  judicially  determined  to arise out of or be based upon any untrue
statement or alleged  untrue  statement or omission or alleged  omission made in
such Registration  Statement or Prospectus or amendment or supplement thereto or
Application  in  reliance  upon  and  in  conformity  with  written  information
furnished  to the Company  through the Holders by or on behalf of any Holder (or
its related  Indemnified  Holder)  specifically for use therein.  This indemnity
agreement  will be in addition to any  liability  that the Company may otherwise
have to the  Indemnified  Holders.  The Company  shall not be liable  under this
Section  6 for any  settlement  of any  claim or  action  effected  without  its
consent, which shall not be unreasonably withheld.

(b) Each Holder,  severally  and not jointly,  will  indemnify and hold harmless
each of the Company and each person, if any, who controls the Company within the
meaning of Section 15 of the  Securities  Act or Section 20 of the  Exchange Act
against any losses,  claims,  damages or liabilities to which the Company or any
such  controlling  person may  become  subject  under the  Securities  Act,  the
Exchange  Act,  or  otherwise,  insofar  as  such  losses,  claims,  damages  or
liabilities  (or actions in respect  thereof) arise out of or are based upon (i)
any untrue  statement or alleged untrue statement of any material fact contained
in the  Registration  Statement or the Prospectus or any amendment or supplement
thereto or any Application or (ii) the omission or the alleged omission to state
therein a material fact required to be stated therein,  or necessary to make the
statements  therein not misleading,  in each case to the extent, but only to the
extent,  that such untrue  statement or alleged untrue  statement or omission or
alleged  omission  was made in  reliance  upon and in  conformity  with  written
information  furnished to the Company through the Holders by or on behalf of any
Holder or its related  Indemnified  Holder  specifically  for use therein;  and,
subject to the limitation  set forth  immediately  preceding  this clause,  will
reimburse,  as incurred,  any legal or other expenses incurred by the Company or
any controlling  person in connection with investigating or defending against or
appearing  as a third party  witness in  connection  with any such loss,  claim,
damage, liability or action in respect thereof. This indemnity agreement will be
in  addition  to any  liability  that  any  Holder  may  otherwise  have  to the
indemnified  parties.  No Holder  shall be liable  under this  Section 6 for any
settlement of any claim or action effected without its consent,  which shall not
be unreasonably  withheld. In no event shall the liability of any selling Holder
hereunder be greater in amount than the dollar  amount of the proceeds  received
by such Holder upon the sale of Transfer  Restricted  Securities  giving rise to
such indemnification obligation.

(c)  Promptly  after  receipt by an  indemnified  party under this  Section 6 of
notice of the  commencement  of any action for which such  indemnified  party is
entitled to  indemnification  under this Section 6, such indemnified party will,
if a claim in respect thereof is to be made against the indemnifying party under
this Section 6, notify the indemnifying party of the commencement  thereof;  but
the  omission so to notify the  indemnifying  party (i) will not relieve it from
any liability  under  paragraph (a) or (b) above unless and to the extent it did
not otherwise learn of such action and such failure results in the forfeiture by
the indemnifying  party of substantial rights and defenses and (ii) will not, in
any  event,   relieve  the  indemnifying  party  from  any  obligations  to  any
indemnified  party  other  than  the  indemnification   obligation  provided  in
paragraphs  (a) and (b) above.  In case any such  action is brought  against any
indemnified  party, and it notifies the  indemnifying  party of the commencement
thereof,  the indemnifying party will be entitled to participate therein and, to
the extent that it may wish, jointly with any other indemnifying party similarly
notified, to assume the defense thereof, with counsel reasonably satisfactory to
such indemnified party; provided, however, that if (i) the use of counsel chosen
by the indemnifying  party to represent the indemnified party would present such
counsel  with a conflict of  interest,  (ii) the  defendants  in any such action
include  both  the  indemnified  party  and  the  indemnifying   party  and  the
indemnified  party shall have been  advised by counsel  that there may be one or
more legal  defenses  available  to it and other  indemnified  parties  that are
different  from or additional to those  available to the  indemnifying  party or
(iii)  the  indemnifying  party  shall  not  have  employed  counsel  reasonably
satisfactory to the indemnified  party to represent the indemnified party within
a reasonable time after notice of the institution of such action,  then, in each
such case, the indemnifying party shall not have the right to direct the defense
of such  action  on  behalf  of such  indemnified  party  or  parties  and  such
indemnified  party or parties shall have the right to select separate counsel to
defend such action on behalf of such indemnified party or parties.  After notice
from the  indemnifying  party to such  indemnified  party of its  election so to
assume the defense  thereof and  approval by such  indemnified  party of counsel
appointed to defend such action,  the  indemnifying  party will not be liable to
such  indemnified  party under this  Section 6 for any legal or other  expenses,
other than  reasonable  costs of  investigation,  subsequently  incurred by such
indemnified  party  in  connection  with the  defense  thereof,  unless  (i) the
indemnified  party shall have employed  separate  counsel in accordance with the
proviso to the immediately  preceding  sentence (it being  understood,  however,
that in connection with such action the  indemnifying  party shall not be liable
for the  expenses  of more  than one  separate  counsel  (in  addition  to local
counsel) in any one action or separate but substantially  similar actions in the
same jurisdiction  arising out of the same general allegations or circumstances,
designated by the Holders in the case of paragraph (a) of this  Section 6 or the
Company  in the  case of  paragraph  (b) of this  Section  6,  representing  the
indemnified  parties under such  paragraph (a) or paragraph (b), as the case may
be, who are parties to such action or  actions) or (ii) the  indemnifying  party
has authorized in writing the employment of counsel for the indemnified party at
the expense of the indemnifying  party.  After such notice from the indemnifying
party to such indemnified  party, the indemnifying  party will not be liable for
the costs  and  expenses  of any  settlement  of such  action  effected  by such
indemnified  party without the consent of the  indemnifying  party,  unless such
indemnified  party  waived in writing its rights  under this Section 6, in which
case the indemnified party may effect such a settlement without such consent.

(d) In  circumstances  in which  the  indemnity  agreement  provided  for in the
preceding  paragraphs of this Section 6 is unavailable or  insufficient  to hold
harmless  an  indemnified  party in respect of any  losses,  claims,  damages or
liabilities (or actions in respect thereof),  each indemnifying  party, in order
to provide for just and equitable  contribution,  shall contribute to the amount
paid or payable by such  indemnified  party as a result of such losses,  claims,
damages or liabilities (or actions in respect  thereof) in such proportion as is
appropriate to reflect (i) the relative  benefits received by the Company on the
one hand and any  Holder  on the  other  from  such  Holder's  sale of  Transfer
Restricted Securities or (ii) if the allocation provided by the foregoing clause
(i) is not permitted by applicable law, not only such relative benefits but also
the  relative  fault of the Company on the one hand and such Holder on the other
in  connection  with the  statements  or  omissions  or  alleged  statements  or
omissions  that  resulted in such losses,  claims,  damages or  liabilities  (or
actions  in  respect  thereof).  The  relative  fault  of the  parties  shall be
determined by reference  to, among other  things,  whether the untrue or alleged
untrue statement of a material fact or the omission or alleged omission to state
a material fact relates to  information  supplied by the Company on the one hand
or such Holder on the other, the parties' relative intent, knowledge,  access to
information  and  opportunity  to correct or prevent such statement or omission,
and any other equitable  considerations  appropriate in the  circumstances.  The
Company and each Holder of Transfer  Restricted  Securities  agree that it would
not be equitable if the amount of such  contribution were determined by pro rata
or per capita allocation or by any other method of allocation that does not take
into account the equitable  considerations  referred to in the first sentence of
this paragraph (d). Notwithstanding the provisions of this Section 6(d), none of
the Holders (or any of their related  Indemnified  Holders) shall be required to
contribute any amount in excess of the amount by which proceeds received by such
Holder from an offering of Transfer Restricted  Securities exceeds the amount of
any damages  which such  Holder has  otherwise  paid or become  liable to pay by
reason of any  untrue  or  alleged  untrue  statement  or  omission  or  alleged
omission. No person guilty of fraudulent  misrepresentation  (within the meaning
of Section 11(f) of the Securities Act) shall be entitled to  contribution  from
any person who was not guilty of such fraudulent misrepresentation. For purposes
of this paragraph  (d), each person,  if any, who controls any Holder within the
meaning of Section 15 of the  Securities  Act or Section 20 of the  Exchange Act
shall have the same rights to contribution as such Holder,  and each person,  if
any, who controls the Company within the meaning of Section 15 of the Securities
Act  or  Section  20 of  the  Exchange  Act,  shall  have  the  same  rights  to
contribution as the Company.
 
7. Rule 144A.  The Company  hereby  agrees with each Holder,  for so long as any
Transfer  Restricted  Securities  remain  outstanding,  to make available to any
Holder or beneficial owner of Transfer Restricted  Securities in connection with
any sale  thereof and any  prospective  purchaser  of such  Transfer  Restricted
Securities from such Holder or beneficial  owner,  the  information  required by
Rule  144A(d)(4)  under the  Securities  Act in order to permit  resales of such
Transfer Restricted Securities pursuant to Rule 144A.

8. Participation in Underwritten Registrations. No Holder may participate in any
Underwritten  Registration  hereunder unless such Holder (a) agrees to sell such
Holder's   Transfer   Restricted   Securities  on  the  basis  provided  in  any
underwriting  arrangements approved by the Persons entitled hereunder to approve
such arrangements and (b) completes and executes all reasonable  questionnaires,
powers of attorney,  indemnities,  underwriting  agreements,  lockup letters and
other documents required under the terms of such underwriting arrangements.

9.  Selection of  Underwriters.  The Holders of Transfer  Restricted  Securities
covered by the Shelf  Registration  Statement  who desire to do so may sell such
Transfer  Restricted  Securities  in  an  Underwritten  Offering.  In  any  such
Underwritten  Offering,  the investment banker or investment bankers and manager
or managers that will administer the offering will be selected by the Holders of
a  majority  in number of shares of  Common  Stock  included  in such  offering;
provided,   that  such  investment  bankers  and  managers  must  be  reasonably
satisfactory to the Company.

10. Miscellaneous.

(a) Remedies. The Company agrees that monetary damages (including the Liquidated
Damages  contemplated  hereby) would not be adequate  compensation  for any loss
incurred by reason of a breach by it of the provisions of this  Agreement  other
than with respect to Registration Defaults and hereby agree to waive the defense
in any action for specific performance that a remedy at law would be adequate.

(b) No  Inconsistent  Agreements.  The Company will not, on or after the date of
this Agreement,  enter into any agreement with respect to its securities that is
inconsistent  with the  rights  granted  to the  Holders  in this  Agreement  or
otherwise  conflicts with the provisions  hereof. The Company has not previously
entered  into any  agreement  granting any  registration  rights with respect to
their securities to any Person which rights conflict with the provisions hereof.

are not  inconsistent  with the rights  granted to the holders of the  Company's
securities under any agreement in effect on the date hereof.

(c)  Amendments  and Waivers.  This  Agreement  may not be amended,  modified or
supplemented,  and  waivers or  consents to or  departures  from the  provisions
hereof may not be given,  unless the Company has obtained the written consent of
Holders of a majority in number of shares of Common Stock issued upon conversion
of the Debentures, as the case may be.

Affiliate of any  investment  company that controls the Borrower shall be deemed

heading  "Applicable Margin for Loans which are Eurodollar Loans" or "Applicable
Margin  for Loans  which are Base  Rate  Loans",  as the case may be, on Annex I
which  corresponds to the  Consolidated  Leverage  Ratio as determined  from the

fiscal period immediately  preceding such Adjustment Date;  provided that in the
event that the financial statements required to be delivered pursuant to Section
6.1(a) or 6.1(b), as applicable, and the related compliance certificate required
to be delivered pursuant to Section 6.2(b), are not delivered when due, then

(i)  if such financial statements and compliance certificate are delivered after
     the date such financial statements and compliance certificate were required
     to be delivered  (without  giving effect to any applicable cure period) and
     the Applicable  Margin increases from that previously in effect as a result
     of the delivery of such financial statements, then the Applicable Margin in
     respect  of the Loans  during  the  period  from the date upon  which  such
     financial  statements were required to be delivered  (without giving effect
     to any applicable  cure period) until the date upon which they actually are

     prior to the expiration of the applicable cure period, then, effective upon
     such  expiration,  for the period  from the date upon which such  financial
     statements and compliance  certificate were required to be delivered (after
     the  expiration  of the  applicable  cure period)  until two Business  Days
     following the date upon which they actually are  delivered,  the Applicable
     Margin in  respect of Loans  shall be 0.00% per annum,  in the case of Base
     Rate Loans,  and 1.50% per annum, in the case of Eurodollar Loans (it being

Rate in effect on such day, and (b) the Federal Funds  Effective  Rate in effect
on such day plus 1/2 of 1%. For  purposes  hereof:  "Prime  Rate" shall mean the
rate of interest per annum  established from time to time by PNC Bank,  National
Association  as its prime rate in effect at its  principal  office in Pittsburgh
(the Prime Rate not being intended to be the lowest rate of interest  charged by
PNC Bank,  National  Association  in  connection  with  extensions  of credit to
debtors);  and  "Federal  Funds  Effective  Rate" shall mean,  for any day,  the
weighted  average of the rates on  overnight  federal  funds  transactions  with
members of the Federal  Reserve  System  arranged by federal funds  brokers,  as
published on the next  succeeding  Business  Day by the Federal  Reserve Bank of
New York,  or, if such rate is not so published  for any day which is a Business

multiple  thereof  (or,  if  the  then  Available   Commitments  are  less  than
$1,000,000,  such  lesser  amount)  and  (y) in the  case of  Eurodollar  Loans,
$5,000,000 or a whole multiple of $1,000,000 in excess thereof.  Upon receipt of

notify  each  Lender  thereof.  Each Lender will make the amount of its pro rata
share of each borrowing available to the Administrative Agent for the account of
the Borrower at the office of the Administrative Agent specified in Section 10.2
prior to 11:00 A.M.,  New York City time, on the Borrowing Date requested by the

unconditionally  promises to pay to the Administrative  Agent for the account of
the  appropriate  Lender the then unpaid  principal  amount of each Loan of such
Lender on the last day of the  Commitment  Period (or such earlier date on which
the Loans  become due and payable  pursuant to Section 8). The  Borrower  hereby
further agrees to pay interest on the unpaid  principal amount of the Loans from
time to time  outstanding  from the date hereof until payment in full thereof at
the rates per annum, and on the dates, set forth in Section 2.10.

(b) Each Lender shall maintain in accordance  with its usual practice an account

this Agreement.

(c) The  Administrative  Agent,  on behalf of the Borrower,  shall  maintain the

principal  or interest  due and  payable or to become due and  payable  from the
Borrower to each Lender  hereunder and (iii) both the amount of any sum received
by the Administrative  Agent hereunder from the Borrower and each Lender's share
thereof.

(d) The entries made in the Register and the accounts of each Lender  maintained
pursuant to Section 2.4(b) shall, to the extent  permitted by applicable law, be
prima facie  evidence of the  existence  and amounts of the  obligations  of the
Borrower therein recorded;  provided, however, that the failure of any Lender or
the  Administrative  Agent to maintain the Register or any such account,  or any
error therein,  shall not in any manner affect the obligation of the Borrower to
repay (with applicable  interest) the Loans made to such Borrower by such Lender
in accordance with the terms of this Agreement.

(e) The Borrower  agrees that, upon the request to the  Administrative  Agent by
any Lender,  the  Borrower  will execute and deliver to such Lender a promissory
note of the Borrower  evidencing any Loans of such Lender,  substantially in the
form of Exhibit C with appropriate insertions as to date and principal amount (a
"Note").  A Note  and  the  obligation  evidenced  thereby  may be  assigned  or
otherwise  transferred  in  whole  or in  part  only  by  registration  of  such
assignment or transfer of such Note and the obligation  evidenced thereby in the
Register (and each Note shall expressly so provide).  Any assignment or transfer
of all or part of an  obligation  evidenced by a Note shall be registered in the
Register only upon surrender for  registration  of assignment or transfer of the
Note  evidencing  such  obligation,  accompanied by an Assignment and Acceptance
substantially  in the form of Exhibit G duly  executed by the Assignor  thereof,
and thereupon one or more new Notes shall be issued to the  designated  Assignee
and the old Note shall be returned by the  Administrative  Agent to the Borrower
marked "cancelled". No assignment of a Note and the obligation evidenced thereby
shall be  effective  unless it shall have been  recorded in the  Register by the
Administrative Agent as provided in this Section 2.4(e).

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

2.6  Optional  Prepayments.  The  Borrower may at any time and from time to time
prepay the Loans, in whole or in part, without premium or penalty, upon at least
three  Business  Days'  irrevocable  notice to the  Administrative  Agent by the
Borrower,  specifying  the  date  and  amount  of  prepayment  and  whether  the
prepayment is of  Eurodollar  Loans,  Base Rate Loans or a combination  thereof,
and, if of a combination thereof, the amount allocable to each, provided that if
a Eurodollar  Loan is prepaid on any day other than the last day of the Interest
Period applicable thereto the Borrower shall also pay any amounts owing pursuant
to Section 2.17. Upon receipt of any such notice, the Administrative Agent shall
promptly  notify each Lender  thereof.  If any such notice is given,  the amount
specified in such notice shall be due and payable on the date specified therein,
together  with  accrued  interest  to such date on the amount  prepaid.  Partial
prepayments of Loans shall be in an aggregate  principal amount of $1,000,000 or
a whole multiple thereof.

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

(b) If any Capital  Stock of the  Borrower or any of its  Subsidiaries  shall be
issued or sold after the Closing Date (except any Capital Stock issued as a part
of the  consideration  of and in connection  with a Permitted  Acquisition),  an
amount  equal to 75% of the Net Cash  Proceeds  thereof  shall be applied on the
date of such issuance or sale toward the prepayment of the Loans as set forth in
paragraph (d) of this Section 2.7.

(c) If the Borrower or any of its  Subsidiaries  shall receive Net Cash Proceeds
from the Significant  Disposition permitted under Section 7.6(e), 75% of the Net
Cash  Proceeds  thereof  shall be applied on the date such Net Cash Proceeds are
received toward the prepayment of the Loans and the reduction of the Commitments
as set forth in paragraph (d) of this Section 2.7.

(d) Amounts to be applied in connection with prepayments of Loans and Commitment
reductions  made  pursuant  to this  Section  2.7 shall be applied to prepay the
Loans  and  reduce  permanently  the  Commitments,  pro  rata  according  to the
outstanding amounts of Commitments.  Any such reduction of the Commitments shall
be accompanied by prepayment of the Loans to the extent, if any, that the sum of
the Aggregate Outstanding Extensions of Credit of all Lenders exceeds the amount
of the  aggregate  Commitments  as so reduced,  provided  that if the  aggregate
principal  amount of Loans  then  outstanding  is less  than the  amount of such
excess  (because L/C  Obligations  constitute a portion  thereof),  the Borrower
shall, to the extent of the balance of such excess,  replace outstanding Letters
of  Credit  and/or  deposit  an  amount  in  cash in a cash  collateral  account
established  with the  Administrative  Agent for the  benefit of the  Lenders on
terms and  conditions  satisfactory  to the  Administrative  Agent.  Amounts  on
deposit in the cash  collateral  account  shall be  invested  as directed by the
Borrower  subject to the approval of the  Administrative  Agent,  which approval
shall not be unreasonably  withheld.  The application of any prepayment pursuant
to this  Section  2.7  shall be made  first to Base  Rate  Loans  and  second to
Eurodollar  Loans,  provided that at the request of the Borrower the application
of any  prepayment  to any  Eurodollar  Loan may be delayed  until the end of an
Interest Period (or Interest  Periods) so that such  application does not result
in the  incurrence by any Lender of any loss or expense under Section 2.17,  and
during  such  delay,  the  Administrative  Agent  shall  hold the amount of such
prepayment in a cash collateral account. Each prepayment of the Loans under this
Section  2.7  shall  be  accompanied  by  accrued  interest  to the date of such
prepayment on the amount prepaid.

2.8 Conversion and Continuation Options. (a) The Borrower may elect from time to
time to convert Eurodollar Loans to Base Rate Loans by giving the Administrative
Agent at least two Business  Days' prior  irrevocable  notice of such  election,
provided that any such  conversion  of Eurodollar  Loans may only be made on the
last day of an Interest Period with respect thereto. The Borrower may elect from
time to time to  convert  Base Rate  Loans to  Eurodollar  Loans by  giving  the
Administrative  Agent at least three Business Days' prior irrevocable  notice of
such election.  Any such notice of conversion to Eurodollar  Loans shall specify
the length of the initial  Interest  Period  therefor.  Upon receipt of any such
notice, the Administrative  Agent shall promptly notify each Lender thereof. All
or any part of outstanding Eurodollar Loans and Base Rate Loans may be converted
as provided herein, provided that (i) no Loan may be converted into a Eurodollar
Loan (A) when any  Event of  Default  has  occurred  and is  continuing  and the
Administrative Agent has or the Required Lenders have determined in its or their
sole discretion not to permit such a conversion or (B) having an Interest Period
in excess of one month  prior to the date  which is the  earlier of (y) 120 days
after  the  Closing  Date or (z) the date the  initial  syndication  of Loans is
completed by the  Arranger  and (ii) no Loan may be converted  into a Eurodollar
Loan after the date that is one month prior to the Termination Date.

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

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

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

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

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

(d) Interest shall be payable in arrears on each Interest Payment Date, provided
that interest  accruing  pursuant to paragraph (c) of this Section 2.10 shall be
payable from time to time on demand.

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

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

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

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

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

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

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

(b) Unless the  Administrative  Agent shall have been notified in writing by any
Lender prior to a borrowing that such Lender will not make the amount that would
constitute its share of such borrowing  available to the  Administrative  Agent,
the  Administrative  Agent may assume  that such  Lender is making  such  amount
available to the  Administrative  Agent,  and the  Administrative  Agent may, in
reliance upon such  assumption,  make available to the Borrower a  corresponding
amount. If such amount is not made available to the Administrative  Agent by the
required  time on the  Borrowing  Date  therefor,  such Lender  shall pay to the
Administrative  Agent,  on demand,  such amount with interest  thereon at a rate
equal to the daily  average  Federal Funds  Effective  Rate for the period until
such Lender makes such amount immediately available to the Administrative Agent.
A certificate of the  Administrative  Agent submitted to any Lender with respect
to any amounts  owing under this  Section  2.13(b)  shall be  conclusive  in the
absence of manifest  error. If such Lender's share of such borrowing is not made
available to the Administrative  Agent by such Lender within three Business Days
of such  Borrowing  Date,  the  Administrative  Agent  shall also be entitled to
recover such amount with  interest  thereon at the rate per annum  applicable to
Base Rate Loans  hereunder,  on demand,  from the  Borrower  (together  with any
amounts due under  Section 2.17,  calculated as if such Lender's failure to fund
such amount were a failure of the  Borrower to borrow such amount  after  having
given  notice of such  borrowing).  Nothing  herein shall be deemed to limit the
rights of the Borrower against any defaulting Lender.

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

2.14 Illegality.  Notwithstanding any other provision herein, if the adoption of
or any change in any Requirement of Law or in the  interpretation or application
thereof  shall make it unlawful  for any Lender to make or  maintain  Eurodollar
Loans as  contemplated  by this  Agreement,  (a) the  commitment  of such Lender
hereunder  to make  Eurodollar  Loans,  continue  Eurodollar  Loans  as such and
convert Base Rate Loans to Eurodollar Loans shall forthwith be suspended and (b)
such Lender's  Loans then  outstanding  as Eurodollar  Loans,  if any,  shall be
converted  automatically  to Base Rate Loans on the respective  last days of the
then current  Interest Periods with respect to such Loans or within such earlier
period as required by law. If any such conversion of a Eurodollar Loan occurs on
a day which is not the last day of the then current Interest Period with respect
thereto,  the Borrower shall pay to such Lender such amounts,  if any, as may be
required pursuant to Section 2.17.

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

(i) shall subject any Lender to any tax of any kind  whatsoever  with respect to
this  Agreement,  any  Note,  any  Letter  of  Credit,  any  Application  or any
Eurodollar  Loan made by it, or change the basis of taxation of payments to such
Lender in respect  thereof (except for taxes covered by Section 2.16 and changes
in the rate of tax (whether characterized as income,  franchise or other tax) on
the overall net income of such Lender);

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

(iii) shall impose on such Lender any other condition;

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

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

(c) If any Lender becomes  entitled to claim any additional  amounts pursuant to
this  subsection,  it shall  promptly  notify the  Borrower  (with a copy to the
Administrative Agent) of the event by reason of which it has become so entitled.
A certificate  as to any  additional  amounts  payable  pursuant to this Section
2.15,  together  with a  calculation  thereof  in  reasonable  detail,  shall be
submitted  by  the  affected  Lender  to  the  Borrower  (with  a  copy  to  the
Administrative Agent) and such certificate shall be conclusive in the absence of
manifest error.  The  obligations of the Borrower  pursuant to this Section 2.15
shall survive the termination of this Agreement and the payment of the Notes and
all other amounts payable hereunder.

2.16 Taxes.  (a) All payments made by the Borrower  under this Agreement and the
Notes shall be made free and clear of, and without  deduction or withholding for
or on account of, any present or future  income,  stamp or other taxes,  levies,
imposts,  duties,  charges,  fees, deductions or withholdings,  now or hereafter
imposed, levied, collected,  withheld or assessed by any Governmental Authority,
excluding  net income taxes and franchise  taxes  (imposed in lieu of net income
taxes)  imposed  on the  Administrative  Agent or any  Lender  as a result  of a
present or former connection between the Administrative Agent or such Lender and
the  jurisdiction  of  the  Governmental  Authority  imposing  such  tax  or any
political  subdivision  or taxing  authority  thereof or therein (other than any
such  connection  arising  solely from the  Administrative  Agent or such Lender
having  executed,  delivered or performed its  obligations or received a payment
under,  or enforced,  this  Agreement or any other Loan  Document).  If any such
non-excluded  taxes,  levies,  imposts,  duties,  charges,  fees,  deductions or
withholdings ("Non-Excluded Taxes") are required to be withheld from any amounts
payable to the Administrative  Agent or any Lender hereunder or under the Notes,
the  amounts so  payable to the  Administrative  Agent or such  Lender  shall be
increased to the extent necessary to yield to the  Administrative  Agent or such
Lender  (after  payment of all  Non-Excluded  Taxes)  interest or any such other
amounts  payable  hereunder  at the rates or in the  amounts  specified  in this
Agreement  and the  Notes,  provided,  however,  that the  Borrower  shall  make
payments  net of and after  deduction  for  Non-Excluded  Taxes and shall not be
required to increase any such amounts payable to any Non-U.S. Lender (as defined
below) that fails to comply with  Section  2.16(b).  Whenever  any  Non-Excluded
Taxes are  payable by the  Borrower,  as promptly  as  possible  thereafter  the
Borrower shall send to the  Administrative  Agent for its own account or for the
account of such  Lender,  as the case may be, a  certified  copy of an  original
official  receipt  received by the  Borrower  showing  payment  thereof.  If the
Borrower fails to pay any Non-Excluded  Taxes when due to the appropriate taxing
authority or fails to remit to the Administrative Agent the required receipts or
other  required   documentary   evidence,   the  Borrower  shall  indemnify  the
Administrative  Agent and the Lenders for any  Non-Excluded  Taxes,  incremental
taxes, interest or penalties that may become payable by the Administrative Agent
or any Lender as a result of any such  failure.  The  agreements in this Section
2.16 shall  survive the  termination  of this  Agreement  and the payment of the
Notes and all other amounts payable hereunder.

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

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

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

Further,  each  Non-U.S.  Lender  agrees  to  deliver  to the  Borrower  and the
Administrative  Agent, and if applicable,  the assigning Lender (or, in the case
of a Participant,  to the Lender from which the related participation shall have
been purchased) two further duly completed and signed copies of such Forms 1001,
4224, W-8 or W-9, as the case may be, or successor and related applicable forms,
on or  before  the date that any such  form  expires  or  becomes  obsolete  and
promptly  after the  occurrence  of any event  requiring  a change from the most
recent form(s) previously  delivered by it to the Borrower or the Administrative
Agent (or,  in the case of a  Participant,  to the Lender from which the related
participation  shall have been purchased) in accordance  with applicable  United
States  laws and  regulations;  unless,  in any such case,  any change in law or
regulation  has occurred  subsequent  to the date such Lender  became a party to
this  Agreement  (or in the  case  of a  Participant,  the  date on  which  such
Participant  purchased the related  participation)  which renders all such forms
inapplicable or which would prevent such Lender (or  Participant)  from properly
completing  and  executing  any such form  with  respect  to it and such  Lender
promptly notifies the Borrower and the Administrative  Agent (or, in the case of
a Participant,  the Lender from which the related  participation shall have been
purchased) if it is no longer able to deliver,  or if it is required to withdraw
or cancel,  any form or  statement  previously  delivered by it pursuant to this
Section 2.16(b). A Non-U.S.  Lender shall not be required to deliver any form or
statement  pursuant  to the  immediately  preceding  sentences  in this  Section
2.16(b)  that such  Non-U.S.  Lender is not  legally  able to deliver  (it being
understood  and agreed that the Borrower  shall  withhold or deduct such amounts
from any payments  made to such  Non-U.S.  Lender that the  Borrower  reasonably
determines  are required by law and that  payments  resulting  from a failure to
comply with this  paragraph  (b) shall not be subject to payment or indemnity by
the Borrower pursuant to Section 2.16(a)).

2.17  Indemnity.  The Borrower  agrees to indemnify each Lender and to hold each
Lender  harmless from any loss or expense which such Lender may sustain or incur
as a  consequence  of  (a) default  by the  Borrower in making a  borrowing  of,
conversion into or continuation of Eurodollar Loans after the Borrower has given
a  notice  requesting  the  same  in  accordance  with  the  provisions  of this
Agreement,  (b)  default  by the  Borrower  in making any  prepayment  after the
Borrower has given a notice  thereof in accordance  with the  provisions of this
Agreement or (c) the making of a prepayment of  Eurodollar  Loans on a day which
is  not  the  last  day  of  an  Interest  Period  with  respect  thereto.  Such
indemnification  shall not exceed the sum of (i) an  amount equal to the excess,
if any, of (A) the amount of interest  which would have accrued on the amount so
prepaid,  or not so borrowed,  converted or  continued,  for the period from the
date of such prepayment or of such failure to borrow, convert or continue to the
last day of such  Interest  Period  (or,  in the case of a  failure  to  borrow,
convert or continue,  the Interest  Period that would have commenced on the date
of such failure) in each case at the applicable  rate of interest for such Loans
provided for herein (excluding, however, the Applicable Margin included therein,
if any) over (B) the  amount  of  interest  (as  reasonably  determined  by such
Lender)  which would have  accrued to such Lender on such amount by placing such
amount on deposit for a comparable  period with leading  banks in the  interbank
eurodollar  market plus (ii) any  transaction costs of such Lender in connection
with the related  funding or  redeployment  of funds.  A  certificate  as to any
amounts  payable  pursuant to this Section  2.17,  together  with a  calculation
thereof in reasonable detail, shall be submitted to the Borrower by any affected
Lender and such  certificate  shall be  conclusive  in the  absence of  manifest
error.  This covenant  shall survive the  termination  of this Agreement and the
payment of the Notes and all other amounts payable hereunder.

2.18 Change of Lending  Office.  Each Lender agrees that, upon the occurrence of
any event  giving rise to the  operation of Section  2.14,  2.15(a) or 2.16 with
respect to such Lender,  it will, if requested by the Borrower,  use  reasonable
efforts (subject to overall policy  considerations  of such Lender) to designate
another  lending  office for any Loans affected by such event with the object of
avoiding the consequences of such event;  provided that such designation is made
on terms that,  in the sole  judgment of such Lender,  cause such Lender and its
lending  office(s)  to  suffer  no  material   economic,   legal  or  regulatory
disadvantage,  and  provided,  further,  that nothing in this Section 2.18 shall
affect or postpone any of the  obligations  of the Borrower or the rights of any
Lender pursuant to Section 2.14, 2.15(a) or 2.16.

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

2.20  Replacement of Lenders.  If no Event of Default then exists,  the Borrower
may replace any Lender (the "Replaced Lender") if an event occurs giving rise to
the  operation of Section 2.14 or Section  2.15,  which  results in the Replaced
Lender  charging to Borrower  increased costs in excess of those being generally
charged  by the  other  Lenders  and such  Lender is not able to  eliminate  the
increased  costs pursuant to Section 2.18. The Replaced Lender shall be replaced
with one or more banks,  financial  institutions,  or other  entities  which are
reasonably  acceptable to the Administrative Agent (each a "Replacement Lender")
under the terms set out in Section 10.6(c). Upon execution of the Assignment and
Acceptance  referred to in Section  10.6(c),  payment of amounts  referred to in
Section 10.6(c),  and delivery to the Replacement Lender of the appropriate Note
or Notes  executed by  Borrower,  the  Replacement  Lender shall become a Lender
under this  Agreement and the Replaced  Lender shall no longer be a Lender under
this Agreement,  except with respect to  indemnification  provisions  under this
Agreement, which shall survive as to such Replaced Lender.

                          SECTION 3. LETTERS OF CREDIT

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

(b) Each Letter of Credit  issued after the Closing Date shall be subject to the
Uniform Customs and, to the extent not inconsistent  therewith,  the laws of the
State of New York.

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

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

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

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

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

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

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

3.5 Reimbursement  Obligation of the Borrower.  The Borrower agrees to reimburse
the  Issuing  Lender on each  date on which  the  Issuing  Lender  notifies  the
Borrower of the date and amount of a draft  presented under any Letter of Credit
and paid by the Issuing  Lender for the amount of (a) such draft so paid and (b)
any taxes,  fees,  charges or other  costs or  expenses  incurred by the Issuing
Lender in connection  with such payment.  Each such payment shall be made to the
Issuing  Lender at its address for notices  specified  herein in lawful money of
the United States and in immediately  available funds. Interest shall be payable
to the Issuing  Lender on any and all amounts drawn under Letters of Credit from
the date of such drawing until the date three Business Days after receipt by the
Borrower from the Issuing Lender of notice of such drawing at the rate set forth
in Section 2.10(b) for Loans,  and thereafter  until payment in full at the rate
set forth in Section 2.10(c).

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

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

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

                    SECTION 4. REPRESENTATIONS AND WARRANTIES

To induce the Arranger,  the Administrative  Agent, the Collateral Agent and the
Lenders  to enter  into  this  Agreement  and to make  the  Loans  and  issue or
participate  in the  Letters of  Credit,  the  Borrower  hereby  represents  and
warrants to the Arranger,  the  Administrative  Agent,  the Collateral Agent and
each Lender that:

4.1 Financial Condition.  (a) The unaudited pro forma consolidated balance sheet
of the Borrower as at September 30, 1997 (including the notes thereto) (the "Pro
Forma Balance  Sheet"),  copies of which have  heretofore been furnished to each
Lender,  has been prepared giving effect (as if such events had occurred on such
date) to the  borrowings  under this  Agreement  contemplated  to be made on the
Closing Date and the use of proceeds  thereof and the payment of estimated  fees
and  expenses in  connection  therewith.  The Pro Forma  Balance  Sheet has been
prepared based on the best information  available to the Borrower as of the date
of delivery thereof and presents fairly in all material  respects on a pro forma
basis the  estimated  consolidated  financial  position  of the  Borrower  as of
September 30, 1997, assuming that the events specified in the preceding sentence
had actually occurred at such date.

(b) The audited  consolidated balance sheets of the Borrower as at June 30, 1997
and June 30, 1996 and the related audited consolidated  statements of income and
of cash flows for the fiscal years ended on such dates, reported on by KPMG Peat
Marwick LLP, copies of which have heretofore been furnished to each Lender,  are
complete  and  correct  and  present   fairly  in  all  material   respects  the
consolidated  financial  condition  of the  Borrower as at such  dates,  and the
consolidated  results of operations and  consolidated  cash flows for the fiscal
years then ended.

All such financial  statements  described in this Section 4.1(b),  including the
related schedules and notes thereto,  have been prepared in accordance with GAAP
applied consistently throughout the periods involved (except as approved by such
accountants  and  as  disclosed  therein).  Except  for  contingent  obligations
incurred in the ordinary course of business, the Borrower had at the date of the
most recent  audited  balance  sheet  referred to above no material  undisclosed
liabilities, Guarantee Obligations, contingent liability or liability for taxes,
nor any material  long-term  lease or unusual  forward or long-term  commitment,
including,  without  limitation,  any interest rate or foreign  currency swap or
exchange  transaction,  which is not  reflected in such balance  sheet or in the
notes  thereto.  During the period from June 30, 1997 to and  including the date
hereof there has been no sale,  transfer or other disposition by the Borrower or
any of its  Consolidated  Subsidiaries of any material part of their business or
property.

4.2 No Change.  (a) Since June 30, 1997,  there has been no development or event
which has had or could reasonably be expected to have a Material Adverse Effect,
and (b) during the period from June 30, 1997 to and including the date hereof no
dividends  or other  distributions  have  been  declared,  paid or made upon the
Capital  Stock of the Borrower nor has any of the Capital  Stock of the Borrower
been  redeemed,  retired,  purchased  or  otherwise  acquired  for  value by the
Borrower,  except for the notice that the Borrower has received  that it will be
required  to  repurchase  approximately  16,000  shares of Capital  Stock of the
Borrower from a former  employee of the Borrower and which Capital Stock will be
purchased by the Borrower in due course.

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

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

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

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

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

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

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

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

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

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

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

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

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

4.16  Purpose of Loans;  Limitations  on Use. The proceeds of the Loans shall be
used to finance Permitted Acquisitions and capital expenditures,  to finance the
repurchase  from time to time the  outstanding  Capital Stock of the Borrower to
the extent permitted by subsection 7.7 and for general corporate purposes of the
Borrower and its Subsidiaries  (including Excluded Subsidiaries) in the ordinary
course of business; provided, that the amount of proceeds of the Loans which may
be used for Permitted Acquisitions of oil and gas properties shall be limited to
an amount equal to the lesser of (a) $25,000,000 and (b) 65% of the value of the
oil and gas properties of Odessa Exploration  Incorporated  (after giving effect
to any such  Permitted  Acquisition),  which  value shall be  calculated  as the
present  value  discounted  at 10% of future net revenue  relating to all proved
developed   producing  reserves  and  proved  undeveloped   reserves  from  such
properties.  In addition,  if at least 90% of the original outstanding principal
amount  of the  Convertible  Subordinated  Debentures  or the  1997  Convertible
Subordinated  Notes shall have been converted into common stock of the Borrower,
the Borrower may use proceeds of the Loans to repurchase or redeem the remaining
outstanding Convertible Subordinated Debentures or 1997 Convertible Subordinated
Notes, as applicable, as permitted by Section 7.10.

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

(a) the Borrower and each of its Subsidiaries:  (i) are, and to the knowledge of
the  executive  management of the Borrower  within the period of all  applicable
statutes  of  limitation   have  been,  in   compliance   with  all   applicable
Environmental  Laws;  (ii) hold all  Environmental  Permits (each of which is in
full force and effect)  required for any of their current  operations or for any
property owned,  leased, or otherwise operated by any of them; (iii) are, and to
the knowledge of the executive  management of the Borrower  within the period of
all applicable statutes of limitation have been, in compliance with all of their
Environmental   Permits;  and  (iv)  reasonably  believe  that:  each  of  their
Environmental  Permits  required for their  continued  operations will be timely
renewed  and  complied   with,   without   material   expense;   any  additional
Environmental  Permits  that  may be  required  of any of them  will  be  timely
obtained and complied with,  without material  expense;  and compliance with any
Environmental Law that is or is reasonably expected by the Borrower's  executive
management  to become  applicable  to any of them will be  timely  attained  and
maintained, without material expense.

(b) To the knowledge of the executive  management of the Borrower,  Materials of
Environmental  Concern  are not  present  at, on,  under,  in, or about any real
property now or formerly owned, leased or operated by the Borrower or any of its
Subsidiaries  or at any  other  location  (including,  without  limitation,  any
location to which Materials of  Environmental  Concern have been sent for re-use
or recycling or for treatment,  storage,  or disposal) which could reasonably be
expected  to  (i)  give  rise  to  liability  of  the  Borrower  or  any  of its
Subsidiaries under any applicable Environmental Law or otherwise result in costs
to the Borrower or any of its Subsidiaries, or (ii) interfere with the continued
operations of the Borrower or any of its Subsidiaries,  or (iii) impair the fair
saleable  value of any real  property  owned or leased by the Borrower or any of
its Subsidiaries.
 
(c) There is no judicial,  administrative, or arbitral proceeding (including any
notice of violation or alleged violation) under or relating to any Environmental
Law to which the Borrower or any of its  Subsidiaries is, or to the knowledge of
the  executive  management  of the  Borrower  will be,  named as a party that is
pending  or, to the  knowledge  of the  executive  management  of the  Borrower,
threatened.

(d) Neither the  Borrower nor any of its  Subsidiaries  has received any written
request for information,  or been notified that it is a potentially  responsible
party under or relating to the  federal  Comprehensive  Environmental  Response,
Compensation, and Liability Act or any similar Environmental Law.

(e) Neither the Borrower nor any of its  Subsidiaries has entered into or agreed
to any consent decree,  order, or settlement or other agreement,  nor is subject
to any  judgment,  decree,  or  order  or  other  agreement,  in  any  judicial,
administrative,  arbitral,  or  other  forum,  relating  to  compliance  with or
liability under any Environmental Law.

(f) To the  knowledge of the executive  management of the Borrower,  neither the
Borrower nor any of its  Subsidiaries  has assumed or  retained,  by contract or
operation of law, any  liabilities of any kind,  fixed or  contingent,  known or
unknown, under or relating to any Environmental Law.

For purposes of Section 8, each of the foregoing  representations and warranties
contained  in this  Section  4.17  that is  qualified  by the  knowledge  of the
executive management of the Borrower shall be deemed not to be so qualified.

4.18  Accuracy of  Information.  No statement or  information  contained in this
Agreement,  any other Loan Document, the Confidential  Information Memorandum or
any other  document,  certificate  or statement  furnished to the Arranger,  the

in connection with the transactions  contemplated by this Agreement or the other
Loan Documents, contained as of the date such statement,  information,  document
or certificate was so furnished any untrue statement of a material fact or, with
all such statements and information  being taken as a whole,  omitted to state a
material  fact  necessary in order to make the  statements  contained  herein or
therein not misleading.  It is understood that no  representation or warranty is
made concerning the forecasts, estimates, pro forma information, projections and

There is no fact known to the  executive  management  of the Borrower that could
reasonably  be  expected  to have a Material  Adverse  Effect  that has not been

such Pledged Securities and other  instruments,  negotiable  documents,  chattel
paper and money and the proceeds  thereof,  as security for the  Obligations (as

and  superior in right to any other  Person,  except for  inchoate tax liens for
obligations to be paid in the ordinary course of business.

(b) The Master  Guarantee  and  Collateral  Agreement  is effective to create in
favor of the  Collateral  Agent,  for the  benefit  of the  Lenders,  a security
interest  which has attached  (as that term is used in Section  9-203 of the New

described in Section 4.19(a)), to the extent that the Loan Parties to the Master
Guarantee and Collateral Agreement have rights in such Collateral,  and proceeds
thereof,  and when financing  statements in appropriate  form are properly filed

covered by certificates of title issued by any State, when the security interest
of the  Collateral  Agent  has  been  noted  on such  certificate  of  title  in
accordance  with  the  certificate  of  title  laws of such  State,  the  Master
Guarantee and  Collateral  Agreement  shall  constitute a perfected Lien on, and
security  interest  in, all right,  title and  interest  of the Loan  Parties in
substantially all of such Collateral and the proceeds  thereof,  as security for

extent  such  violations  could  not,  individually  or  in  the  aggregate,  be

assessment report shall be delivered to the  Administrative  Agent by the end of

Administrative  Agent  shall  have the  right,  but shall not have any duty,  to
obtain, review or discuss any such report.

(e) Promptly upon the Administrative  Agent's request if there has been an Event
of Default  which has not been fully and timely cured,  permit an  Environmental
Consultant whom the Administrative Agent in its discretion designates to perform

surface  water,  groundwater,  and/or other media in or about  property owned or
leased by the Borrower,  or on which  operations of the Borrower  otherwise take

the Borrower or any of its Domestic Subsidiaries having a purchase price (or, if
acquired through a merger or stock  acquisition,  a fair market value) in excess
of $1,000,000 and which,  after giving effect to such  acquisition  and assuming
that a perfected  first priority Lien thereon were not granted to the Collateral
Agent would result in the  Collateral  Agent having a perfected  first  priority
Lien on less than 80% in value  (calculated  as provided in Section 4.24) of the
reserves  contained in all of the oil and gas properties of the Borrower and its
Domestic  Subsidiaries,  promptly  (and in any event  within  30 days  after the

reasonably  satisfactory to the Collateral  Agent, and (ii) if  requested by the

registered or recorded in order to create in favor of the Collateral  Agent, for
the benefit of the Lenders, a perfected Lien on all of the Vehicles covered by a
certificate  of title,  prior and superior in right to any other  Person  (other
than with respect to Liens expressly  permitted by Section 7.3), which documents
shall  be in  proper  form  for  filing,  registration  or  recordation  in each
jurisdiction  in which the filing,  registration  or  recordation  thereof is so
required or requested.

(c) Lien  Searches.  The  Collateral  Agent shall have received the results of a
recent lien search by a Person satisfactory to the Administrative  Agent, of the
Uniform  Commercial Code,  judgment and tax lien filings in each of the relevant

shall reveal no material Liens on any of such assets except for Liens  permitted
by Section 7.3. If any Liens not  permitted by Section 7.3 appear as a result of
such lien search, promptly (and in any event within 60 days of completion of the

executed  legal opinion of a local counsel  satisfactory  to the  Administrative
Agent. Each such legal opinion shall be substantially in the form of Exhibit E-1
hereto and shall cover such matters incident to the transactions contemplated by
this Agreement as the Administrative Agent may reasonably require.

its inability to, pay its debts as they become due; or

(g) (i) Any Person shall engage in any "prohibited  transaction"  (as defined in
Section 406 of ERISA or  Section 4975  of the Code) involving any Plan, (ii) any
"accumulated  funding deficiency" (as defined in Section 302 of ERISA),  whether
or not waived,  shall exist with respect to any Plan or any Lien in favor of the
PBGC or a Plan  shall  arise on the  assets  of any Loan  Party or any  Commonly
Controlled  Entity,  (iii) a  Reportable  Event shall occur with  respect to, or
proceedings  shall commence to have a trustee  appointed,  or a trustee shall be
appointed,  to administer  or to  terminate,  any Single  Employer  Plan,  which
Reportable  Event or commencement of proceedings or appointment of a trustee is,
in the  reasonable  opinion  of the  Required  Lenders,  likely to result in the
termination  of such Plan for  purposes  of Title IV of ERISA,  (iv) any  Single
Employer Plan shall  terminate  for purposes of Title IV of ERISA,  (v) any Loan

and in each case in clauses (i) through  (vi)  above,  such event or  condition,
together with all other such events or conditions,  if any,  could,  in the sole
judgment  of the  Required  Lenders,  reasonably  be expected to have a Material
Adverse Effect; or

(h) One or more  judgments or decrees  shall be entered  against the Borrower or
any of its  Subsidiaries  (other than  Servicios)  involving in the  aggregate a
liability  (not paid or fully covered by  insurance) of $2,000,000 or more,  and

cease, for any reason,  to be in full force and effect, or any Loan Party or any
Affiliate of any Loan Party shall so assert, or any material Lien created by any
of the Security  Documents  shall cease to be enforceable and of the same effect
and priority purported to be created thereby; or

(j) Any Change of Control shall occur;

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

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

                              SECTION 9. THE AGENTS

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

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

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

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

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

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

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

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

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

10.1 Amendments and Waivers.  Neither this  Agreement,  any other Loan Document,
nor any terms hereof or thereof may be amended,  supplemented or modified except
in accordance with the provisions of this Section 10.1. The Required Lenders and
each Loan Party which is party to the relevant Loan  Documents may, or, with the
written consent of the Required Lenders,  the Administrative Agent and each Loan
Party which is a party to the relevant Loan Document may, from time to time, (a)
enter into written  amendments,  supplements or modifications  hereto and to the
other Loan  Documents for the purpose of adding any provisions to this Agreement
or the other Loan  Documents or changing in any manner the rights of the Lenders
or of the Loan Parties  hereunder or thereunder or (b) waive,  on such terms and
conditions as the Required Lenders or the Administrative  Agent, as the case may
be, may specify in such instrument, any of the requirements of this Agreement or
the  other  Loan   Documents  or  any  Default  or  Event  of  Default  and  its
consequences;  provided that no such waiver and no such amendment, supplement or
modification  shall  (i)  forgive  the  principal  amount of any Loan or any L/C
Obligation,  or extend the final  scheduled  date of  maturity  of any Loan,  or
reduce  the  stated  rate of any  interest,  fee or letter of credit  commission
payable  hereunder  or extend  the  scheduled  date of any  payment  thereof  or
increase the amount or extend the expiration date of any Lender's Commitment, or
waive any  mandatory  prepayment  or make any change in the  application  of any
prepayment of the Loans  specified in the first sentence of Section 2.7(f) or in
Section 2.13(a), or the right to refuse prepayments set forth in the penultimate
sentence  of Section  2.6,  in each case  without  the  consent  of each  Lender

Loan Party of any of its rights and  obligations  under this  Agreement  and the
other Loan  Documents or release all or a substantial  portion of the Collateral
(other than in connection with any sale or other disposition of assets permitted
by  Section  7.6  or  pursuant  to  Section  10.17)  or  any  guarantee  of  the
Obligations,  in each case, without the written consent of all the Lenders, (iv)
amend, modify or waive any provision of Section 9 without the written consent of
the Agents, or (v) amend, modify or waive any provision of Section 3 without the
written consent of the Issuing  Lender.  Any such waiver and any such amendment,
supplement or modification  shall apply equally to each of the Lenders and shall
be binding upon the Loan Parties, the Lenders, the Agents and all future holders
of the Notes. In the case of any waiver,  the Loan Parties,  the Lenders and the
Agents shall be restored to their former position and rights hereunder and under
the other Loan  Documents,  and any Default or Event of Default  waived shall be
deemed to be cured and not  continuing;  but no such waiver  shall extend to any
subsequent or other  Default or Event of Default or impair any right  consequent
thereon.

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

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

(b) Any Lender may, without the consent of the Borrower,  in the ordinary course
of its business and in accordance  with  applicable law, at any time sell to one
or more banks or other entities (each, a "Participant")  participating interests
in any Loan owing to such Lender,  any Note held by such Lender,  any Commitment
of such  Lender or any other  interest of such  Lender  hereunder  and under the
other  Loan  Documents.  In  the  event  of  any  such  sale  by a  Lender  of a
participating  interest to a Participant,  such Lender's  obligations under this
Agreement to the other parties to this Agreement  shall remain  unchanged,  such
Lender shall remain solely responsible for the performance thereof,  such Lender
shall remain the holder of any such Note for all purposes  under this  Agreement
and the other Loan  Documents,  and the  Borrower and the  Administrative  Agent
shall  continue to deal solely and directly with such Lender in connection  with
such Lender's  rights and  obligations  under this  Agreement and the other Loan
Documents.  In no event shall any Participant under any such  participation have
any right to  approve  any  amendment  or waiver  of any  provision  of any Loan
Document, or any consent to any departure by any Loan Party therefrom, except to
the extent that such amendment, waiver or consent would reduce the principal of,
or interest  on, the Notes or any fees payable  hereunder,  postpone the date of
the final  maturity of the Notes,  consent to the  assignment or transfer by the
Borrower of any of its rights and obligations under this Agreement and the other
Loan Documents,  release all or a substantial  portion of the Collateral  (other
than in connection  with any sale or other  disposition  of assets  permitted by
Section  7.6) or any  guarantee of the  Obligations,  in each case to the extent
subject to such  participation.  The Borrower agrees that if amounts outstanding
under  this  Agreement  and the  Notes  are due or  unpaid,  or shall  have been
declared or shall have become due and payable upon the occurrence of an Event of
Default,  each Participant  shall, to the maximum extent permitted by applicable
law,  be deemed to have the right of  setoff  in  respect  of its  participating
interest in amounts  owing under this  Agreement and any Note to the same extent
as if the amount of its  participating  interest were owing  directly to it as a
Lender under this  Agreement or any Note,  provided  that,  in  purchasing  such
participating interest, such Participant shall be deemed to have agreed to share
with the Lenders the proceeds thereof as provided in Section 10.7(a) as fully as
if it were a Lender  hereunder.  The Borrower also agrees that each  Participant
shall be entitled to the benefits of Sections  2.15,  2.16 and 2.17 with respect
to its  participation in the Commitments and the Loans  outstanding from time to
time as if it was a Lender;  provided  that, in the case of Section  2.16,  such
Participant  shall have  complied  with the  requirements  of said  Section  and
provided,  further, that no Participant shall be entitled to receive any greater
amount  pursuant to any such Section than the transferor  Lender would have been
entitled to receive in respect of the amount of the participation transferred by
such transferor Lender to such Participant had no such transfer occurred.

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

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

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

(f) Upon its receipt of an Assignment  and  Acceptance  executed by an assigning
Lender  and an  Assignee  (and,  in the case of an  Assignee  that is not then a
Lender or an affiliate  thereof or a Person under  common  management  with such
Lender,  by the  Borrower,  the  Administrative  Agent and the  Issuing  Lender)
together  with  payment  to  the  Administrative  Agent  of a  registration  and
processing fee of $3,500,  the  Administrative  Agent shall (i) promptly  accept
such  Assignment  and  Acceptance  and  (ii) on the  effective  date  determined
pursuant  thereto record the information  contained  therein in the Register and
give notice of such  acceptance and recordation to the Lenders and the Borrower.
On or prior to such  effective  date,  the  Borrower,  at its own expense,  upon
request,  shall execute and deliver to the Administrative Agent (in exchange for
the Note of the assigning Lender) a new Note to the order of such Assignee in an
amount equal to the  Commitment  assumed by it pursuant to such  Assignment  and
Acceptance  and, if the assigning  Lender has retained a Commitment  Note to the
order of the assigning  Lender in an amount equal to the Commitment  retained by
it hereunder. Such new Notes shall be dated the Closing Date and shall otherwise
be in the form of the Note replaced thereby.

(g) The  Borrower  authorizes  each  Lender to disclose  to any  Participant  or
Assignee  (each,  a  "Transferee")  and any  prospective  Transferee any and all
financial  information in such Lender's  possession  concerning the Borrower and
its  Affiliates  which has been  delivered to such Lender by or on behalf of the
Borrower  pursuant to this  Agreement or which has been delivered to such Lender
by or on  behalf  of the  Borrower  in  connection  with  such  Lender's  credit
evaluation of the Borrower and its Affiliates  prior to becoming a party to this
Agreement.

(h) Nothing  herein  shall  prohibit or restrict any Lender from (i) pledging or
assigning any Note to any Federal Reserve Bank in accordance with applicable law
or (ii) with the prior  consent  of the  Administrative  Agent and the  Borrower
(which,  in  each  case,  shall  not be  unreasonably  withheld  or  delayed  or
conditioned),  pledging  its rights in  connection  with any Loan or Note to any
other Person.

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

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

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

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

10.10  Integration.  This Agreement and the other Loan  Documents  represent the
agreement  of the  Borrower,  the  Administrative  Agent,  the  Arranger and the
Lenders with respect to the subject  matter  hereof,  and there are no promises,
undertakings,  representations  or warranties by the  Administrative  Agent, the
Arranger or any Lender relative to subject matter hereof not expressly set forth
or referred to herein or in the other Loan Documents.

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

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

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

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

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

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

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

10.13 Acknowledgements. The Borrower hereby acknowledges that:

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

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

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

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

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

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

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

10.17 Collateral Release. Upon the occurrence of a Collateral Release Event, the
Liens on the Collateral  granted pursuant to the Security Documents or otherwise
securing  Obligations shall be released  automatically.  Within one Business Day
following the  satisfaction  of the foregoing  conditions and the receipt by the
Administrative  Agent of a certificate of a Responsible  Officer certifying that
such conditions have been satisfied,  the Administrative  Agent shall deliver to
the  Collateral  Agent the notice  required  pursuant to Section 8.16 the Master
Guarantee and Collateral Agreement.

hereby  irrevocably  sells,  assigns and  transfers  to each  Purchasing  Lender
identified  on Schedule I hereto (each a "Purchasing  Lender" and  collectively,
the "Purchasing  Lenders") without recourse to the Transferor  Lender,  and each
Purchasing Lender hereby  irrevocably  purchases and assumes from the Transferor

Effective Date (as defined below), the interests  described in Schedule I hereto
in and to the  Transferor  Lender's  rights  and  obligations  under the  Credit

not created any adverse claim upon the interest  being  assigned by it hereunder
and that such interest is free and clear of any such adverse  claim;  (ii) makes
no representation or warranty and assumes no responsibility  with respect to the
financial  condition  of the  Borrower,  any of its  Subsidiaries  or any  other
obligor  or  the  performance  or  observance  by  the  Borrower,   any  of  its

and such other  documents and  information as it has deemed  appropriate to make
its own credit analysis and decision to enter into this Amendment;  (iii) agrees
that it will, independently and without reliance upon the Transferor Lender, the
Administrative  Agent  or any  other  Lender  and  based on such  documents  and
information as it shall deem  appropriate at the time,  continue to make its own
credit decisions in taking or not taking action under the Credit Agreement,  the
other Loan  Documents or any other  instrument  or document  furnished  pursuant
hereto or thereto; (iv) appoints and authorizes the Administrative Agent to take
such  action as agent on its behalf and to exercise  such powers and  discretion
under the Credit Agreement,  the other Loan Documents or any other instrument or
document   furnished  pursuant  hereto  or  thereto  as  are  delegated  to  the
Administrative  Agent by the terms  thereof,  together  with such  powers as are
incidental  thereto;  and (v) agrees that it will be bound by the  provisions of
the  Credit  Agreement  and will  perform in  accordance  with its terms all the
obligations  which by the  terms of the  Credit  Agreement  are  required  to be
performed by it as a Lender  including,  if it is organized  under the laws of a
jurisdiction  outside the United States,  its obligation  pursuant to subsection
2.16(b) of the Credit Agreement.

(d) In connection  with the foregoing  assignments  and transfers and subject to
the terms and  conditions  hereof,  the Borrower,  the  Transferor  Lender,  the
Purchasing  Lenders  and  the   Administrative   Agent  hereby  agree  that  the

their respective interests as reflected in Exhibit A hereto.

from and after the First  Amendment  Effective  Date, all  participation  of the
Lenders in respect of Letters of Credit  pursuant to subsection  3.4(a) shall be

time and from  time to time upon the  written  request  of the other  Transferor
Lender or any other Purchasing  Lender, it will execute and deliver such further
documents and do such further acts and things as such other party may reasonably
request in order to effect the sale,  assignment  and transfer set forth in this
