corporation duly organized, validly existing and in good standing under the laws
of Delaware and Oklahoma, respectively, and has the requisite corporate power to
own,  lease and operate its properties  and, in the case of Seller,  to carry on
its business as now being  conducted.  Seller is qualified to do business and is
in good  standing  in each  jurisdiction  in which the nature and conduct of its

has all  requisite  corporate  power and  authority  to execute and deliver this
Agreement  and all  other  instruments,  agreements  and other  documents  to be
executed  and  delivered  by  Parent  or  Seller  in  connection  herewith  (the
"Collateral Documents") and to perform its obligations hereunder and thereunder.
The execution and delivery of this  Agreement  and the  Collateral  Documents by
Seller and Parent and the performance of the  transactions  contemplated  hereby
and thereby have been duly and validly authorized by all corporate action on the
part of Seller and  Parent.  This  Agreement  constitutes  the legal,  valid and
binding obligation of Seller and Parent,  enforceable  against Seller and Parent
in  accordance  with its terms,  except as  enforceability  may be  affected  by

creditors'  rights  generally  and general  principles  of equity,  whether in a
proceeding in equity or at law.

Section 4.03.  No  Violation or Consent.  Except as set forth in  Schedule 4.03,
neither the execution and delivery of this  Agreement,  nor the  effectuation by
Seller or Parent of the  transactions  contemplated  hereby (a) will violate any
applicable statute or law, or any rule,  regulation,  order, writ, injunction or
decree of any court or governmental  authority,  or (b) will violate or conflict
with or  constitute a default (or an event which,  with notice or lapse of time,
or both,  would  constitute a default)  under, or will result in the termination
of, or accelerate the performance  required by, or result in the creation of any
lien, security interest, charge or encumbrance upon any of the Assets under, any
term or provision of (i) the Certificate of Incorporation or Bylaws of Seller or
Parent or (ii) any  lease,  contract,  commitment,  understanding,  arrangement,
agreement or restriction of any kind or character to which Seller or Parent is a
party or by which Seller,  Parent or any of the Assets may be bound or affected.
No  filing  with,  or  consent,  approval,   authorization  or  action  by,  any
governmental authority is required in connection with the execution and delivery
by  Seller  or Parent of this  Agreement  or the  effectuation  by Seller of the
transactions  contemplated  hereby or thereby  other than (A) those which if not
made,  obtained or taken would have no material adverse effect on the WSB or the
Assets and (B) those that have been made, obtained or taken.

Section  4.04.   Material   Contracts,   Agreements,   Plans  and   Commitments.
Schedules 1.02(d)  and  1.02(f)  set  forth  a  complete  list  of all  Material

True and complete copies of the Material Contracts and Material Work Orders have
been furnished by Seller to Buyer prior to the date hereof.  Except as set forth
on  Schedule 4.04,  Seller is not in default,  nor but for the requirement  that
notice be given or that a period of time  elapse or both,  would be in  default,
under any of the  Contracts  or Work Orders,  nor to the  knowledge of Seller or
Parent,  is any  other  party  to such  Contracts  or  Work  Orders  in  default
thereunder.

civil,   criminal,   administrative,   arbitration,   or  other  proceedings  or
governmental  investigations  pending or, to the  knowledge of Seller or Parent,

ownership, use, operation or value of the Assets or (c) the conduct of the WSB.

Section 4.07. Environmental Matters. Except as set forth in Schedule 4.07:

     Materials"  means any substance that is defined as hazardous or toxic under
     Environmental  Legal  Requirements or that is known, as of the date of this
     Agreement,  to pose a threat or endangerment to human health, safety or the
     environment  (including,  without limitation,  any asbestos,  formaldehyde,

     waste or toxic material). The term "Environmental Legal Requirements" means
     any and all  laws,  statutes,  ordinances,  rules,  regulations,  orders or
     legally enforceable  requirements of any governmental  authority pertaining
     to health or the  environment  in effect as of the date of this  Agreement,
     including  the Clean Air Act, the  Comprehensive  Environmental,  Response,
     Compensation,  and  Liability  Act of 1980  ("CERCLA"),  the Federal  Water

     Resource  Conservation  and  Recovery  Act  of  1976  ("RCRA"),  the  Toxic
     Substances Control Act, the Hazardous Materials Transportation Act, and the
     Oil  Pollution  Act of  1990,  all as  amended  through  the  date  of this
     Agreement,  and any state or local laws  implementing the foregoing federal
     laws.

(b)  No Hazardous  Materials  have been  disposed or otherwise  released onto or
     under the Real Property by Seller or in connection with the ownership,  use
     or  operation  of the  Assets  of the  conduct  of the WSB by Seller at any
     on-site or off-site  location in  quantities,  concentrations  or locations
     that  require   remedial   action  under  any  such   Environmental   Legal
     Requirements.

(c)  All permits,  licenses or similar  authorizations,  if any,  required to be
     obtained or filed by Seller under any Environmental  Legal  Requirements in
     connection  with the Real  Property,  the  operation  of the  Assets or the
     conduct  of the WSB have  been duly  obtained,  applied  for or filed,  and
     Seller  is in  compliance  in all  material  respects  with the  terms  and
     conditions of such permits, licenses and similar authorizations.

(d)  Neither Seller nor Parent has received any notice or other communication of
     any claims, notices, actions, suits, citations, summons,  investigations or

     condition  of the Real  Property or the Assets,  and there  exists no writ,
     injunction,  decree,  order or  judgment  outstanding,  nor any  pending or
     threatened  claim,  relating  to any  alleged  or  suspected  violation  of
     Environmental  Legal  Requirements  arising  out of the  ownership,  use or
     operation of the Assets,  whether or not corrected to the  satisfaction  of
     the appropriate governmental entity.

(e)  To the  knowledge  of Seller or Parent,  there has been no  exposure of any
     person or  property  to  Hazardous  Materials  on the Real  Property  or in
     connection with the Assets or the WSB that could  reasonably be expected to
     result in a Claim for damages or compensation.

(f)  There are no  underground  storage  tanks (as defined  under  Environmental
     Legal  Requirements)  located  under any of the Real  Property  except  for
     underground  storage tanks that are in compliance with Environmental  Legal
     Requirements and except for such underground  storage tanks the presence of
     which would not have a material adverse effect on the WSB. Each underground
     storage  tank  previously  located  under the Real  Property was removed in
     accordance with  Environmental  Legal Requirements in effect at the time of
     such removal.

(g)  There are no  environmental  conditions  or  circumstances,  including  the
     presence or release of any Hazardous  Materials,  on any property presently
     or  previously  owned,  used or leased by Seller,  which would  result in a
     material  adverse  change in the Assets or the WSB or a Claim against Buyer
     following the Closing.

Section 4.08.  Taxes.  With respect solely to the operation of the WSB:  (a) all
contributions due from Seller pursuant to any unemployment  insurance or workers
compensation  laws and all sales or use taxes which are due or payable by Seller
have been paid in full and will be so paid through the Closing Date;  (b) Seller
has  withheld and paid to, or will cause to be paid to, the  appropriate  taxing
authorities all amounts  required to be withheld from the wages of the employees
of the WSB under state law and the applicable provisions of the Internal Revenue
Code of 1986,  as amended (the  "Code") (and Seller will  continue to do so with
respect to all wages  paid by them prior to the  Closing);  and  (c) Seller  has
timely paid, or will pay prior to the due date therefor, all taxes which, if not
paid,  could result in the  imposition  of a lien or  encumbrance  on the Assets
(except for liens for taxes not yet due) or  otherwise  interfere  with  Buyer's
ability to own and  operate the Assets  after the  Closing.  All taxes  assessed
against  the Real  Property  for the period  commencing  January 1, 1998 will be
prorated  through the Closing Date (based on 1997  assessed  values) with Seller
paying  to  Buyer at  Closing  an  amount  equal to the  portion  of such  taxes
applicable to the period between January 1, 1998 and the Closing Date.

Section 4.09.  Insurance.  Schedule 4.09  sets  forth  a list  of all  insurance
policies,  by which the Assets or the WSB, and any operations  relating thereto,
are  covered  against  present  losses or claims  and which  insurance  provides
coverage consistent with the past conduct of the WSB.

Section 4.10. Labor and Employee Benefits.

(a)  Seller has not at any time had or been  threatened  with any work stoppages
     or other material labor disputes.

(b)  As to any "employee  benefit plan," as such term is defined in Section 3(3)
     of the  Employee  Retirement  Income  Security  Act  of  1974,  as  amended
     ("ERISA")  sponsored or  maintained by Seller within six years prior to the
     Closing Date ("Plan"),  including  without  limitation (i) a  multiemployer
     plan within the meaning of Section  3(37) of ERISA and (ii) a Plan  subject
     to Title IV of ERISA,  there has been no event or condition  which presents
     the material risk of Plan termination,  no accumulated  funding deficiency,
     whether  or not  waived,  within the  meaning  of  Section  302 of ERISA or
     Section 412 of the Code has been incurred,  no reportable  event within the
     meaning of Section 4043 of ERISA (for which the disclosure  requirements of
     Regulation ss2615.3 promulgated by the Pension Benefit Guaranty Corporation
     ("PBGC")  have not been  waived)  has  occurred,  no  notice  of  intent to
     terminate  the  Plan  has  been  given  under  Section  4041 of  ERISA,  no
     proceeding has been instituted under Section 4042 of ERISA to terminate the
     Plan,  no  liability to the PBGC has been  incurred,  and the assets of the
     Plan  equal  or  exceed  the   actuarial   present  value  of  the  benefit
     liabilities,  within the meaning of Section 4041 of ERISA,  under the Plan,
     based  upon  reasonable  actuarial  assumptions  and  the  asset  valuation
     principles  established by the PBGC. For purposes of this Section 4.10, the
     term  "Seller"  shall  collectively  refer to Seller and each other  entity
     which is treated as a single  employer with Seller under Section 414 of the
     Code. No employee benefit plan,  program or arrangement of whatever nature,
     whether or not subject to any provisions of ERISA,  bonus or other employee
     pay practice or leave policy  maintained by Seller (a "Plan"),  will by its
     terms or applicable law, become binding upon or an obligation, liability or
     responsibility  of Buyer,  financial or otherwise.  Seller warrants that no
     Plan  provides  for  payments  of retiree  benefits in any manner such that
     Buyer  would  become  liable  to make  such  payments.  There  have been no
     failures to offer or provide  health  care  continuation  coverage  ("COBRA
     Coverage")  under any employee welfare benefit plan sponsored or maintained
     by Seller  which is  required  under  Sections  601 through 608 of ERISA or
     applicable state law.

(c)  Seller does not maintain or contribute to any multiemployer plan within the
     meaning of Section 3(37) of ERISA.

Section 4.11.   Brokerage  Agreements.  Seller  has  not  entered  (directly  or
indirectly)  into any agreement with any Person that provides for the payment of
any  commission,  brokerage  or "finder's  fee" arising out of the  transaction
contemplated  by this  Agreement  for which  Buyer might have any  liability  or
obligation.

Section 4.12.  Title to Property.  Seller has good and  marketable  title to the
personal and tangible  property  included in the Assets being  acquired by Buyer
under this Agreement,  including,  without  limitation,  the assets described in
Sections 1.02(a), 1.02(b), 1.02(e), 1.02(i), 1.02(k) and 1.02(l), free and clear
of all mortgages, pledges, liens, security interests,  encumbrances or claims of
any kind or nature (collectively,  "Liens"),  except (i) Liens for current taxes
and  assessments  not yet due and payable,  (ii) Liens in existence  that do not
materially  detract from the value thereof or interfere  with the present use of
the  property  subject  thereto  and  (iii) Liens  set  forth on  Schedule  4.12
(collectively, "Permitted Liens").

Section 4.13.  Absence of Certain Changes.  Except as disclosed in Schedule 4.13

May 31, 1998, there has not been:

(a)  any material adverse change in the WSB, taken as a whole;

(b)  any damage,  destruction or loss,  whether  covered by insurance or not, to
     the Assets that could have a material adverse effect on the WSB, taken as a
     whole;

(c)  any  waiver by Seller of any rights  under the  Contracts  or Leases  that,
     singularly or in the aggregate,  are material to the WSB, taken as a whole;
     or

(d)  any intention,  contract,  agreement or commitment on the part of Seller or
     any of its Affiliates to do any of the foregoing.

Section 4.14. Permits.  To Seller's and Parent's  knowledge,  there are no other
permits not listed on Schedule  1.02(g) that are material to the  operation  and
use of the Assets or the conduct of the WSB as currently conducted.  Each of the
Permits and Seller's  rights with respect  thereto is valid and  subsisting,  in
full force and effect,  and enforceable by Seller and Seller is in compliance in
all material  respects  with the terms of each of the  Permits.  To Seller's and
Parent's knowledge, no proceeding is pending or threatened which seeks to repeal
or  limit  any of the  Permits,  and to  Seller's  and  Parent's  knowledge,  no
suspension or cancellation of any Permit is threatened.

Section 4.15.  Employees.  Set forth in Schedule 4.15 is an accurate list of the
employees of the WSB,  which list shall  include their duties and/or job titles,
current salaries and other compensation, date of employment, date of last salary
increase, the number of accrued but unused vacation days to which such employees

cost or other liability to Seller.

Section 4.16.  Customers.  Set forth in Schedule 4.16 is an accurate list of all
customers of the WSB that  constituted 5% or more of the revenues of the WSB for
the fiscal year ended May 31, 1998, including the amount of billings made by the
WSB to such  customers  during such  periods.  Seller has not  received  written
notice that any customer of the WSB intends to cease doing  business  with Buyer
(or  its  successors)  as a  result  of the  consummation  of  the  transactions
contemplated hereby.

Section  4.17.  No  Arrangements  with Respect to Assets.  There are no existing
agreements, options, commitments or rights that have been provided to any person
or entity to acquire any of the Assets to be acquired by Buyer, except for those
contracts  entered into in the normal  course of business  consistent  with past
practices with respect to the sale of inventory of the business.

Section  4.18.   Limitation  of  Representations   and  Warranties.   EXCEPT  AS
SPECIFICALLY SET FORTH IN THIS AGREEMENT,  THE SCHEDULES AND EXHIBITS HERETO AND
ALL OTHER DOCUMENTS EXECUTED BY PARENT OR SELLER IN CONNECTION HEREWITH,  SELLER
MAKES NO REPRESENTATION OR WARRANTY,  AND HEREBY DISCLAIMS ANY REPRESENTATION OR
WARRANTY,  EXPRESS OR IMPLIED,  WHICH  RELATES TO THE RIGS,  THE  EQUIPMENT  AND
ROLLING  STOCK,   THE  VACUUM   TRUCKS,   THE  INVENTORY  OR  THE  FIXTURES  AND
IMPROVEMENTS,   INCLUDING  ANY  WARRANTY  OF  MERCHANTABILITY,   VALUE,  REPAIR,
SUITABILITY OR FITNESS FOR A PARTICULAR USE, OR QUALITY, OR AS TO THE ABSENCE OF
ANY DEFECTS  THEREIN,  WHETHER LATENT OR PATENT,  IT BEING  UNDERSTOOD  THAT THE
RIGS, THE EQUIPMENT AND ROLLING STOCK, THE VACUUM TRUCKS,  THE INVENTORY AND THE
FIXTURES AND IMPROVEMENTS ARE BEING  TRANSFERRED  HEREUNDER "AS IS AND WHERE IS"
WITH ALL FAULTS AND IN THEIR PRESENT  STATE AND  CONDITION.  BUYER  ACKNOWLEDGES
THAT IT HAS EXAMINED AND MADE ITS OWN INDEPENDENT INVESTIGATION AS IT RELATES TO
THE RIGS, THE EQUIPMENT AND ROLLING STOCK, THE VACUUM TRUCKS,  THE INVENTORY AND
THE FIXTURES AND IMPROVEMENTS AND, AS IT RELATES TO SUCH ASSETS,  HAS NOT RELIED
ON ANY  STATEMENTS OF ANY SELLER,  OFFICER OR  REPRESENTATIVE  AS TO VALUES,  OR
CONDITION OR APPRAISALS OF, OR  REPRESENTATIONS OR WARRANTIES (OTHER THAN AS SET
FORTH IN THIS  AGREEMENT,  THE  SCHEDULES  AND  EXHIBITS  HERETO  AND ALL  OTHER
DOCUMENTS EXECUTED BY PARENT OR SELLER IN CONNECTION HEREWITH).  NOTHING IN THIS
SECTION 4.18 SHALL BE  CONSTRUED TO IN ANY WAY DETRACT FROM THE  REPRESENTATIONS
AND WARRANTIES OF SELLER AND PARENT IN SECTION 4.12, 4.13 OR 4.17.

Section 4.19. Absence of Certain Businesses  Practices.  Neither Seller, nor any
officer,  employee or agent of Seller,  or any other person  acting on behalf of
Seller,  has,  within the past five  years,  given or agreed to give any gift or
similar  benefit  (the  fair  market  value of which  exceeded  $10,000)  to any
customer,  supplier,  government  employee  or other  person,  for  purposes  of
influencing such person's judgment or decision,  who is in a position to help or
hinder the profitable conduct of the WSB or the profitable use of the Assets (or
to assist Seller in connection with any actual or proposed transaction) which if
not  given  in the  past,  would  have  had a  material  adverse  effect  on the
profitable  conduct of the WSB or the  profitable  use of the Assets,  or if not
continued in the future,  would have a material adverse effect on the profitable
conduct of the WSB or the profitable use of the Assets.

Section 4.20. Solvency.  Seller is not presently  insolvent,  nor will Seller be
rendered  insolvent by the occurrence of the  transactions  contemplated by this
Agreement.  The term "insolvent," with respect to Seller,  means that the sum of
the present  fair and  saleable  value of Seller's  assets does not and will not
exceed its debts and other probable  liabilities,  and the term "debts" includes
any legal liability  whether matured or unmatured,  liquidated or  unliquidated,
absolute fixed or contingent, disputed or undisputed or secured or unsecured.

Section 4.21. Real Property.

(a)  All of the real  property  owned by  Seller in  connection  with the WSB is
     described on Schedule 1.02(c). Seller has and will convey to Buyer good and
     indefeasible  title to the  Real  Property  free  and  clear of any and all
     Liens.

(b)  The  Real  Property  does  not  violate  any  material  provisions  of  any
     applicable  building code,  fire,  health or safety  regulations,  or other
     governmental  ordinances,  orders or regulations.  No condition exists with
     respect to the Real  Property  which would  prevent,  or require  repair or
     modification  thereof as a prerequisite to Buyer using the Real Property in
     the conduct of the WSB.

(c)  The  zoning  classification  of the  Real  Property  is such  that the Real
     Property may be used as currently used in the WSB.

(d)  There are no parties in  possession  of any portion of the Real Property as
     lessees, tenants, at sufferance or trespassers.

(e)  There is no pending or  threatened  condemnation  or similar  proceeding or
     assessment  affecting the Real  Property,  or any part thereof,  nor is any
     such  proceeding or assessment  contemplated  by any  governmental  body or
     entity.

(f)  Seller has  complied in all material  respects  with all  applicable  laws,
     ordinances,  regulations,  statutes, rules and restrictions relating to the
     Real Property, or any part thereof.

(g)  There  are  water,  sewer,  and  electricity  lines  to the  Real  Property
     presently  sufficient for the conduct of the WSB in the ordinary  course of
     business.

(h)  The Real  Property  has full and free access to and from  public  highways,
     streets  or roads  and,  to the  best of  Seller's  knowledge,  there is no
     pending or  threatened  proceeding by any  governmental  entity which would
     impair or result in the termination of such access.

Section 4.22.  Intellectual  Property.  No intellectual property is necessary to
the conduct of the WSB as  presently  conducted.  Neither  Seller nor Parent has
received notice of any claim for  infringement or interference or other conflict
by Seller with the asserted rights of others with respect with any  intellectual
property.

     authorized by all  corporate  action on the part of Buyer.  This  Agreement
     constitutes the legal, valid and binding  obligation of Buyer,  enforceable

(b)  Neither the execution and delivery of this  Agreement nor the  effectuation
     by Buyer of the  transactions  contemplated  hereby  (a) will  violate  any
     statute or law, or any rule, regulation,  order, writ, injunction or decree
     of any court or  governmental  authority,  or (b) will  violate or conflict
     with or  constitute a default (or an event  which,  with notice or lapse of

     obtained or taken.

Section 5.03.   Litigation.  There  are  no  civil,  criminal,   administrative,
arbitration or other proceedings or governmental  investigations pending, or, to
the  knowledge  of Buyer,  threatened  against  Buyer that could  jeopardize  or
adversely affect any of the transactions contemplated by this Agreement.

Section 5.04.   Brokerage  Agreements.   Buyer  has  not  entered  (directly  or

any  commission,  brokerage  or "finder's  fee" arising out of the  transactions
contemplated  by this  Agreement  for which Seller  might have any  liability or
obligation.

                                   ARTICLE VI

                               COVENANTS OF SELLER

Section 6.01.  Conduct  of Seller  Pending  the  Closing  and the  Vacuum  Truck

(b)  except in the  ordinary  course  of  business,  not (i) enter  into any (A)

     past  practices,  (ii) may  terminate any contract which is not included in
     the Assets and (iii) shall not be required to make any  expenditures out of
     the ordinary  course of business in order to comply with the  covenants set

     Schedule 4.09;

(h)  operate its business only in the usual,  regular, and ordinary manner so as
     to maintain the goodwill it now enjoys and, to the extent  consistent  with
     such operation,  preserve intact its present  business  organization,  keep
     available the services of its present officers and employees,  and preserve
     its relationship with customer, suppliers, jobbers, distributors and others
     having business dealing with it;

     reclassify  any  shares  of its  capital  stock,  or  acquire,  or agree to
     acquire, any shares of its capital stock;

(l)  not declare any  dividend on shares of its capital  stock or make any other
     non-cash distribution of assets to the holders thereof;

(m)  promptly  notify  Buyer in writing of any event or  condition  which  could
     reasonably be expected to have a material  adverse  effect on the Assets or
     the WSB (a "Material Adverse Event"); and

(n)  not directly or indirectly  (i) solicit,  initiate or encourage any inquiry
     or Acquisition Proposal (defined below) from any person or (ii) participate
     in any  discussions  or  negotiations  regarding,  or furnish to any person
     other than Buyer or its representatives any information with respect to, or
     otherwise  facilitate  or encourage any  Acquisition  Proposal by any other
     person. As used herein "Acquired Proposal" means any proposal for a merger,
     consolidation  or other business  combination  involving  Seller or for the
     acquisition or purchase of any equity interest in, or a material portion of
     the assets of, Seller,  other than the transactions with Buyer contemplated
     by this Agreement.  Seller shall promptly communicate to Buyer the terms of
     any such  written  Acquisition  Proposals  which  they may  receive  or any
     written  inquiries  made  to  them or any of  their  respective  directors,
     officers, representatives or agents.

Section 6.02.  Employees.  As soon as  reasonably  administratively  practicable
after the Closing,  Seller agrees to pay or otherwise provide for payment of all
amounts  due and  payable to the  Transferred  Employees  (as defined in Section
11.02(a)) as of such date and through the Closing,  including  salaries,  wages,
commissions  and bonuses due and arising out of their  employment  with  Seller,
except with respect to any obligations  expressly  assumed by Buyer as set forth
in Section 2.05(a)(3) hereof. As soon as reasonably administratively practicable
after the Vacuum Truck  Closing,  Seller agrees to pay or otherwise  provide for
payment of all amounts due and payable to the Vacuum Truck Transferred Employees
(as  defined in  Section  11.02(a))  as of such date and  through  the  Closing,
including salaries,  wages, commissions and bonuses due and arising out of their
employment with Seller, except with respect to any obligations expressly assumed
by Buyer as set forth in Section 2.05(a)(3) hereof.

Section 6.03.  Access.  Seller  will give to Buyer and its  representatives  and
agents,  after  reasonable  advance notice to Seller,  and as often as Buyer may
reasonably  request,  full  and  complete  access  to the  Assets  and the  WSB,
including,  without  limitation,  such of Seller's  assets,  books,  agreements,
papers and records,  employees and financial statements pertaining to the Assets
or the WSB, and Seller will cause its officers,  employees, agents, advisors and
other  representatives  to cooperate fully with Buyer's officers,  employees and
other representatives in the course of such obligation.

Section 6.04.  Consents.  Seller will use all commercially reasonable efforts to
satisfy or cause to be satisfied  all of the  conditions to Closing set forth in
Article VIII hereof,  including  obtaining,  prior to the Closing,  all consents
necessary to the effectuation of the transactions  contemplated hereby. All such
consents will be in writing and executed  counterparts thereof will be delivered
to Buyer  promptly after receipt by Seller  thereof,  but in no event later than
immediately prior to the Closing.

Section 6.05.  Additional Action to Assure Transfers.  Nothing in this Agreement
shall  be  construed  to  assign  any  Contract  that is by its  terms or by law
nonassignable without the consent of the other party or parties thereto,  unless
such  consent  shall have been given,  or as to which all the  remedies  for the
enforcement  thereof  enjoyed by Seller  would  not,  as a matter of law pass to
Buyer as an incident  of the  assignments  provided  for by this  Agreement.  In
order,  however,  to  provide  Buyer  the  full  realization  and  value  of the
Contracts,  Seller, at and after the Closing, will, at the request and under the
direction  of Buyer  and in the  name of  Seller  or  otherwise  as Buyer  shall
specify,  take or cause to be taken all such  action  and do or cause to be done
all such things as shall be necessary or proper to (a) assure that the rights of
Seller under the Contracts shall be preserved for the benefit of Buyer,  and (b)
facilitate receipt by Buyer of the consideration to which Seller would otherwise
be entitled in and under the Contracts which consideration shall be held for the
benefit  of,  and shall be  delivered  to,  Buyer.  In order to  accomplish  the
foregoing, Seller may designate Buyer as subcontractor (under mutually agreeable
terms and conditions) to perform obligations of Seller under the Contracts if so
requested by Buyer.

                                   ARTICLE VII

                               COVENANTS OF BUYER

Section 7.01.  Cooperation.  Buyer  acknowledges that Seller may have continuing
obligations  on  certain  matters   relating  to  the  WSB  after  the  Closing.
Accordingly,  Buyer  agrees to grant to Seller  and its  representatives  access
during normal  business  hours to such books and records as may be necessary for
the  defense  and/or  disposition  of such  other  matters  that  Seller  may be
obligated  to  perform  relating  to the WSB,  and to  furnish  such  additional
information as Seller or its representatives may reasonably request.

Section 7.02. Post-Closing  Employment.  After the Closing Date, Buyer agrees to
provide employee benefits to the Transferred Employees through one of its wholly
owned subsidiaries that are, in all material respects, no less favorable to such
transferred  employees than the employee benefits provided to similarly situated
employees of Buyer located in the same geographic  region under employee benefit
plans  sponsored by Buyer;  provided  that such  Transferred  Employees  will be
subject to the terms and  conditions of the  applicable  employee  benefit plan,
subject,  in all cases, to the provisions of this Section 7.02. After the Vacuum
Truck  Closing  Date,  Buyer agrees to provide  employee  benefits to the Vacuum
Truck  Transferred  Employees  that  are,  in all  material  respects,  no  less
favorable to such transferred  employees than the employee  benefits provided to
similarly  situated  employees of Buyer  located in the same  geographic  region
under employee benefit plans sponsored by Buyer; provided that such Vacuum Truck
Transferred  Employees  will be  subject  to the  terms  and  conditions  of the
applicable  employee benefit plan,  subject,  in all cases, to the provisions of
this Section 7.02.  Further,  Buyer shall (i) provide the Transferred  Employees
and the Vacuum Truck Transferred  Employees and their eligible  dependents as of
the Closing  Date or the Vacuum  Truck  Closing  Date,  as the case may be, with
coverage in a group medical and dental plan maintained by Buyer,  (ii) waive any
preexisting condition limitations applicable to the Transferred Employees or the
Vacuum Truck  Transferred  Employees  under  Buyer's  group  medical plan to the
extent that a Transferred  Employee's or a Vacuum Truck  Transferred  Employee's
condition would not have operated as a preexisting  condition  limitation  under
Seller's group medical plan,  (iii) cause any employee  pension benefit plan (as
such term is defined in Section 3(2) of ERISA) which is intended to be qualified
under  Section  401 of the Code to be amended to  provide  that the  Transferred
Employees and the Vacuum Truck  Transferred  Employees  shall receive credit for
participation  and  vesting  purposes  under  such  plan  for  their  period  of
continuous  employment  with  Seller and its  predecessors  to the  extent  such
predecessor employment was recognized by Seller, and (iv) credit the Transferred
Employees and the Vacuum Truck  Transferred  Employees under each other employee
benefit plan or policy of Buyer for their period of continuous  employment  with
Seller  or its  predecessors  to the  extent  such  predecessor  employment  was
recognized by Seller.

Section  7.03.   Performance  of  Obligations.   Buyer  agrees  to  perform  all
obligations  under the Contracts  and Work Orders for all periods  following the
Closing  Date as such  obligations  become  due,  except to the extent that such
obligations  arise solely from a breach or default by Seller under the Contracts
or Work Orders prior to the Closing Date.

Section 7.04.  Consents.  Buyer will use all commercially  reasonable efforts to
satisfy or cause to be satisfied  all of the  conditions to Closing set forth in
Article IX hereof,  including  obtaining,  prior to the  Closing,  all  consents
necessary to the effectuation of the transactions  contemplated hereby. All such
consents will be in writing and executed  counterparts thereof will be delivered
to Seller  promptly after receipt by Buyer  thereof,  but in no event later than
immediately prior to the Closing.

                                  ARTICLE VIII

                        CONDITIONS TO BUYER'S OBLIGATIONS

with all covenants and conditions  required by this Agreement to be performed or
complied  with prior to or at the  Closing,  and  Seller  and Parent  shall have

compliance  and  conformity  with  such  covenants  and  conditions  in  a  form
reasonably satisfactory to Buyer.

Section 8.04.  Conveyance  of  Documents.  At the  Closing,  Seller  shall  have

     of its obligations hereunder,  or (ii) would impose any material limitation
     on the ability of Seller  effectively to convey full rights of ownership to
     (A) the Assets (other than the Vacuum Trucks) to Buyer as of the Closing or
     (B) the Vacuum Trucks to Buyer as of the Vacuum Truck Closing Date.

(b)  With respect to the Closing and the Vacuum Truck Closing,  no action,  suit
     or  proceeding  before any court,  tribunal or any  governmental  agency or
     authority shall be pending against Seller or Buyer challenging the validity
     or legality of the transactions contemplated by this Agreement.

Section 8.06.  Third-Party  Consents.  All  consents  required to be obtained in
connection  with the assignment by Seller to Buyer of the Assets (other than the
Vacuum Trucks) at the Closing, or the Vacuum Trucks at the Vacuum Truck Closing,
shall have been received and delivered to Buyer.

Section 8.07.  Opinion of Counsel.  Buyer shall have received an opinion,  dated
the Closing Date, from Doerner,  Saunders, Daniel & Anderson, L.L.P., counsel to
Seller and Parent, in the form attached hereto as Schedule 8.07.

Section 8.08. Environmental Matters.

(a)  Seller  will  have  caused to be  conducted  a Phase I  Environmental  Site
     Assessment (a "Phase I")  (including any updates as are, in the judgment of
     Buyer,  necessary;  provided  that such  updates  shall be at Buyer's  sole
     expense),  and if deemed  necessary by Buyer,  at Buyer's sole  expense,  a
     Phase II  Environmental  Site Assessment (a "Phase II"), on all of the Real
     Property,  both of which shall be conducted in  conformance  with the scope
     and  limitations  of ASTM  Standard  Practice  E1527 (except for the survey
     requirements  included  therein) by an environmental  surveyor  approved by
     Buyer. Buyer will be satisfied, in its reasonable judgment, that either (x)
     the  results  of such  Phase I's and,  if  necessary,  such Phase II's have
     revealed no  environmental  condition  except for Permitted  Conditions (as
     defined below) that would result in any liability or obligation on the part
     of Buyer or would, except for any Permitted Conditions, adversely affect or
     reduce the value of the Real Property, or (y) any such conditions have been
     cured or  appropriate  agreements  shall be in place to provide  for such a
     cure.  As  used  herein,   the  term  "Permitted   Conditions"   means  any
     environmental  conditions  on the Real  Property  that  would (i) result in
     liabilities  or  obligations  routinely  incurred  in  connection  with the
     ordinary  operation of the business or (ii) adversely  affect or reduce the
     value of the Real Property,  in the case of clauses (i) and (ii) above,  by
     no more that $10,000 in the  aggregate.  If neither of the  conditions  set
     forth in clauses (x) and (y) above can be met with  respect to any tract of
     Real  Property,  Seller shall have the option to exclude such tract of Real
     Property  from the Assets and the  Purchase  Price  shall be reduced by the
     value of such  excluded  tract or tracts  (as  agreed  to in good  faith by
     Seller and Buyer).

(b)  If all  environmental  conditions  on the  Liberty,  Texas  tract  of  Real
     Property  (the "Liberty  Property")  have not been  Remediated  (as defined
     below) as of the  Closing,  Buyer shall have the right to withhold  $25,000
     from the Purchase Price.  Buyer shall have no obligation to pay such amount
     to Seller until all  environmental  conditions on the Liberty  Property are
     Remediated.  Once the  Liberty  Property  has been  Remediated,  Buyer will
     deliver  to Seller  the  entire  amount  withheld  by Buyer at the  Closing
     without interest thereon.  As used herein,  the term "Remediated" means the
     receipt by Buyer of a Phase I on the  Liberty  Property  which,  in Buyer's
     reasonable judgment, demonstrates that, except for Permitted Conditions, no
     environmental  conditions  exist that would (i) result in any  liability or
     obligation  on the part of Buyer or (ii)  materially  adversely  affect  or
     reduce the value of the Liberty Property.

Section 8.09.  Real  Estate  Matters.  Buyer  shall have  obtained,  at its sole
expense,  a commitment to issue an owner's title policy insuring that Buyer will
own,  upon the  Closing,  fee simple  title to the Real  Property  subject to no
exceptions other than those encumbrances reasonably acceptable to Buyer.

                                   ARTICLE IX

                       CONDITIONS TO SELLER'S OBLIGATIONS

or at the Vacuum Truck Closing.

Section 9.03.  Payment of Purchase Price. At the Closing,  or in the case of the
Vacuum  Trucks,  the Vacuum  Truck  Closing,  Buyer shall have  delivered to the

conditions.

Section 9.05.  Opinion of Counsel.  Seller shall have received an opinion, dated
the Closing Date,  from Jack D. Loftis,  Jr.,  General  Counsel of Buyer, in the

                                    ARTICLE X

                  SURVIVAL OF REPRESENTATIONS; INDEMNIFICATIONS

Section 10.01.  Survival of Representations.  The representations and warranties
in this  Agreement  and in any  certificate  delivered  pursuant  hereto  shall,
notwithstanding  any  investigation  made by or on behalf of the parties hereto,
survive the Closing solely for purposes of this Article X and shall terminate at
the close of business one year after the Closing Date; provided,  however,  that
(i) the representations  and warranties  contained in Section 4.07 shall survive
the Closing  and shall  terminate  at the close of business  two years after the
Closing Date,  (ii) the  representations  and  warranties  contained in Sections
4.02,  4.12,  4.17 and 4.20 shall survive the Closing and shall terminate at the
close  of  business   four  years   after  the   Closing   Date  and  (iii)  the
representations  and  warranties  contained  in Section  4.08 shall  survive the
Closing and shall  terminate upon the  expiration of the  applicable  statute of
limitations period therefor.

Section 10.02.  Agreement to Indemnify Buyer.  Seller and Parent shall,  jointly
and severally indemnify, defend and hold harmless Buyer and any of its officers,
directors,  shareholders,  affiliates,  representatives  or agents  (the  "Buyer
Group") from and against all losses, damages,  liabilities,  costs and expenses,
including, without limitation, reasonable attorneys' fees and expenses, incurred
by Buyer,  the Buyer Group or any member  thereof,  directly or  indirectly,  by
reason of or resulting from (a) a breach or inaccuracy of any  representation or
warranty of Seller or Parent  contained in or made  pursuant to this  Agreement;
(b) any  failure to perform any covenant or obligation  required to be performed
by Seller or Parent  under this  Agreement;  or (c) the  Unassumed  Obligations.
Buyer agrees to give Seller prompt notice of any action or  proceedings to which
they or any of the Buyer  Group  believe  they  have a right of  indemnification
hereunder,  and  failure  to  give  such  notice  shall  be  a  breach  of  this
Section 10.02; provided, however, that the failure to provide notice promptly to
Seller shall not release  Seller from any liability  that they may have to Buyer
or the Buyer Group,  except to the extent that the failure to give prompt notice
materially   prejudices   Seller's   ability  to  defend  any  such  actions  or
proceedings.  If any action or proceeding  shall be brought against Buyer or the
Buyer Group, and Seller shall be notified or otherwise learn of the commencement
thereof,  then Seller shall have the right to participate in, and, to the extent
that it may wish,  to  assume  the  defense  thereof,  and  after  notice of its
election  to assume the defense  thereof,  Seller will not be liable to Buyer or
the Buyer Group for any further legal or other expenses incurred by Buyer or the
Buyer  Group in  connection  with any  such  action  or  proceeding.  Buyer  may
participate actively, at its expense,  after notice of assumption of defense has
been given by Seller, in any  negotiations,  lawsuit or other resolution of such
claim.  Buyer shall have the right to approve any out-of-court  settlement if it
would divest Buyer of any Asset or otherwise  materially affect the WSB acquired
by Buyer; provided that such approval shall not be unreasonably withheld.

Section 10.03.  Agreement to Indemnify Seller. Buyer hereby agrees to indemnify,
defend and hold harmless Seller and any of its respective  officers,  directors,
shareholders  or  Affiliates  (the "Seller  Group") from and against all losses,
damages,  liabilities,   costs  and  expenses,  including,  without  limitation,
reasonable attorneys' fees and expenses, incurred by Seller, the Seller Group or
any member thereof, directly or indirectly, by reason of or resulting from (a) a
breach  or  inaccuracy  of any  material  representation  or  warranty  of Buyer
contained in or made pursuant to this Agreement;  (b) any failure to perform any
covenant or obligation  required to be performed by Buyer under this  Agreement;
or (c) any claims or damages  relating to the Assumed  Obligations  set forth in
Section 2.05.  Seller  agrees  to give  Buyer  prompt  notice  of any  action or
proceeding to which it or any of the Seller Group  believes they have a right of
indemnification  hereunder, and failure to give such notice shall be a breach of
this  Section 10.03;  provided,  however,  that the  failure to  provide  notice
promptly to Buyer shall not release Buyer from any liability that Buyer may have
to Seller or the Seller  Group,  except to the extent  that the  failure to give
prompt notice materially  prejudices  Buyer's ability to defend any such actions
or proceedings.  If any action or proceeding  shall be brought against Seller or
the  Seller  Group,  and  Buyer  shall be  notified  or  otherwise  learn of the
commencement thereof, then Buyer shall have the right to participate in, and, to
the extent that they may wish, to assume the defense  thereof,  and after notice
of its  election  to assume  the  defense  thereof,  Buyer will not be liable to
Seller or the Seller Group for any further legal or other  expenses  incurred by
Seller or the Seller  Group in  connection  with any such action or  proceeding.
Seller may participate actively,  at its expense,  after notice of assumption of
defense  has  been  given  by  Buyer,  in any  negotiations,  lawsuit  or  other
resolution of such claim.

Section 10.04.  Additional  Agreements  Concerning  Indemnification.  Buyer  and
Seller and Parent  agree that if either of them or the Buyer Group or the Seller
Group,  respectively,  becomes entitled to indemnification  under this Agreement
(the  "Indemnified  Party"),  they shall  cooperate with the party  obligated to
provide  such  indemnification   (the  "Indemnifying   Party")  and  permit  the
Indemnifying Party reasonable access to the Indemnified Party's books,  records,
facilities and employees for the purpose of permitting the Indemnifying Party to
perform its obligations under this Article X.

Section 10.05.  Minimum and  Maximum  Amounts.  Notwithstanding  anything to the
contrary in Article X hereof,  (i) the Indemnifying  Party shall not be required
to make any payment pursuant to the terms hereof or otherwise in connection with
any claims,  demands,  actions,  losses, expenses or other liability incurred by
the  Indemnifying  Party in  connection  with or arising  out of this  Agreement
("Liabilities")  until the  aggregate  amount of all  Liabilities  exceeds  on a
cumulative basis Three Hundred Thousand Dollars ($300,000) (and then only to the
extent of the excess),  and (ii) except as provided,  in the following sentence,
the maximum  amount that an  Indemnifying  Party shall be required to pay to the
Indemnified  Party or anyone claiming by, through or under them, with respect to
Liabilities,  shall be One Million Five Hundred  Thousand  Dollars  ($1,500,000)
(the "Maximum  Amount").  The  limitations  set forth in this Section 10.05 with
respect to the Maximum Amount shall not apply (i) to Liabilities  arising out of
the breach of representations  and warranties  contained in Sections 4.02, 4.11,
4.12, 4.17,  4.20, 5.02 and 5.04, (ii) to Liabilities  arising out of any matter
subject to indemnification pursuant to clause (c) of Section 10.02 or clause (c)
of  Section  10.03 or (iii) to  Liabilities  arising  out of the  breach  of the
covenant contained in Section 11.04.

For purposes of the indemnification obligations set forth in this Section 10.05,
all representations,  warranties and covenants set forth in this Agreement shall
be assumed to be free of qualifications with respect to materiality.

Section 10.06.  Exclusive Remedy.  Subsequent to Closing, the provisions of this
Article X shall provide the exclusive  monetary,  but not injunctive,  remedy of
the parties for any breach of this Agreement.

                                   ARTICLE XI

                      ADDITIONAL AGREEMENTS OF THE PARTIES

Section 11.01.  Public  Announcements.  Buyer and Seller shall consult with each
other before issuing any press release or otherwise making any public statements
with respect to this Agreement or the transactions contemplated hereby and shall
not issue any such press release or make any such public statement prior to such
consultation.

Section 11.02. Employees.

(a)  Buyer shall  through one of its wholly  owned  subsidiaries  employ (i) all
     employees of Seller who (A) have been  engaged  directly in the WSB (except
     for the operations relating to the Vacuum Trucks),  including rig crews and
     supervisors  and  certain  administrative  personnel,  (B)  are  listed  on
     Schedule  4.15,  (C) are in active  service on the Closing  Date and not on
     leave of absence for any health or non-health related reason or confined in
     any health  care  facility,  and (D) pass a drug test  and/or the  physical
     exam, which, to the extent applicable, will be administered by Buyer or its
     subsidiaries  prior to the  Closing,  other than those  listed on  Schedule
     11.02 (the"Transferred Employees") and (ii) all Vacuum Truck Employees who
     pass  the  drug  test  and/or  the  physical  exam,  which,  to the  extent
     applicable,  will be administered by Buyer or its subsidiaries prior to the
     Closing,  other than those  listed on  Schedule  11.02 (the  "Vacuum  Truck
     Transferred  Employees").  Seller shall remain solely responsible for those
     employees  that are  listed  on  Schedule  11.02 and  Buyer  shall  have no
     responsibility  therefor,  including  responsibility for severance or other
     benefits for such employees.  Seller shall provide eligible  employees (and
     dependants   thereof)  with  COBRA  Coverage  upon  their   termination  of
     employment  with Seller  according to the applicable  requirements of ERISA
     and the Code and any applicable state law. Seller will retain liability for
     all workers'  compensation claims for work-related injuries occurring prior
     to the Closing  Date,  or,  with  respect to the Vacuum  Truck  Transferred
     Employees, the Vacuum Truck Closing Date.

(b)  As soon as  administratively  practicable  following the Closing Date,  or,
     with respect to the Vacuum Truck  Transferred  Employees,  the Vacuum Truck
     Closing Date,  Seller shall cause to be transferred from the trustee of the
     Flint Companies  Hourly Savings Plus Plan and from the trustee of the Flint
     Engineering & Construction Co. Savings Plus Plan (collectively, the "Seller
     Plan") to the  trustee of the Key Energy  Group,  Inc.  401(k)  Savings and
     Retirement  Plan  ("Buyer's  401(k)  Plan") an amount in cash  equal to the
     aggregate  account  balances of the  Transferred  Employees  and the Vacuum
     Truck Transferred Employees who transfer to employment with Buyer under the
     Seller Plan  determined as of the transfer date (which shall be a valuation
     date) in  accordance  with the  methods  of  valuation  as set forth in the
     Seller Plan; provided, however, that to the extent any Transferred Employee
     or any Vacuum Truck Transferred Employee owes any amount to the Seller Plan
     pursuant to the terms of a loan from such plan to such Transferred Employee
     or  Vacuum  Truck  Transferred  Employee,  as the case may be,  an  in-kind
     transfer of such loan shall be made in lieu of the  transfer of cash.  From
     and after the date of such transfer,  Buyer shall cause Buyer's 401(k) Plan
     to assume the  obligations  of the  Seller  Plan with  respect to  benefits
     accrued  by the  Transferred  Employees  and the Vacuum  Truck  Transferred
     Employees  under the Seller  Plan,  and the Seller  Plan shall  cease to be
     responsible  therefor.  Buyer and  Seller  shall  cooperate  in making  all
     appropriate  arrangements  and  filings,  if any,  in  connection  with the
     transfer  described  above.  Further,  Buyer and Seller shall cooperate and
     take such  actions  as are  necessary  to permit the  continuation  of loan
     repayments by Transferred  Employees and Vacuum Truck Transferred Employees
     to the Seller Plan by payroll deductions during the period beginning on the
     Closing Date, or in the case of the Vacuum Truck Transferred Employees, the
     Vacuum Truck Closing Date, and ending on the date of the transfer described
     in this Subsection. Seller represents, covenants and agrees with respect to
     the Seller Plan, and Buyer represents, covenants and agrees with respect to
     Buyer's 401(k) Plan, that, as of the date of the transfer described in this
     paragraph, such plan will satisfy the requirements of Sections 401(a), (k),
     and (m) of the  Code.  Buyer and  Seller  agree to enter  into a  "spin-off
     agreement"  to record and  effectuate  the transfer of plan assets from the
     Seller  Plan trust to  Buyer's  401(k)  Plan  trust for the  benefit of the
     Transferred  Employees,  the Vacuum Truck  Transferred  Employees and their
     respective beneficiaries.

(c)  Effective  as of the  Closing,  Buyer  assumes,  and  Seller  shall have no
     further  responsibility  for, any accrued but unused  vacation  liabilities
     that are set forth on Schedule  4.15 as of the Closing  Date.  Buyer agrees
     that  employees  of the WSB  shall  be  entitled  to use such  vacation  in
     accordance with the vacation  policy  currently in effect as of the Closing
     Date.

Section 11.03.  Non-Solicitation.  For a  period  of one  year  from the date of
Closing,  neither  Seller nor any of its  directors  will directly or indirectly
solicit, or attempt to solicit,  for employment any Transferred  Employee or any
Vacuum Truck Transferred Employee.

Section 11.04.  Covenant  Not to Compete.  Seller and Parent  covenant and agree
that,  for a period of three  years  from the date of Closing  (the  "Noncompete
Term"), neither they nor any of their subsidiaries will, directly or indirectly,
(i) engage  in the WSB  acquired  by Buyer  within  the  states of Utah,  Texas,
Oklahoma, Colorado, Kansas, North Dakota, New Mexico or Montana (the "Restricted
Territory")  or (ii) own any interest in any person,  corporation,  partnership,
proprietorship  or  other  business  organization  or  association  (whether  as
stockholder, agent, independent contractor, consultant, representative, partner,
lender (other than through a passive,  non-control  investment in an entity that
acts as a lender)  or  otherwise)  which  derives a  substantial  portion of its
revenues from business  operations which compete with the WSB acquired by Buyer.
Notwithstanding anything to the contrary in this Agreement,  Seller may (A) make
passive  investments  of five  percent  (5%) or less in any  outstanding  equity
securities of corporations whose equity securities are publicly traded and which
compete with the WSB, (B) acquire outstanding equity securities of a corporation
that competes in the WSB in the Restricted Territory whose equity securities are
publicly   traded  in  connection   with  the  sale  of  the  capital  stock  or
substantially all of the assets of Servicios Petroleros Flint C.A., a Venezuelan
corporation,  the capital stock of which is owned by Flint Construction  Company
of South America,  Inc., a majority  shareholder  of Parent;  provided that such
acquisition will not result in Seller (or a successor  thereof) being a majority
or controlling  shareholder of such entity, or (C) maintain a passive,  minority
investment in an entity to be formed with SCF Partners,  Inc. (the "SCF Entity")
in conjunction  with the sale of the remaining assets of Seller even in the case
that  the SCF  Entity  invests  in an  entity  that  competes  in the WSB in the
Restricted Territory;  provided that no employee,  officer or director of Seller
or Parent (or successors  thereof) may work for, render assistance or advice to,
or participate in the management of the well servicing  business of such entity,
except for any work,  assistance,  advice or participation  that may be rendered
indirectly  and solely as a result of such  employee's,  officer's or director's
obligations or duties as a director of such entity.

In  addition,  Seller and Parent agree that for a period of three years from the
Closing Date, they will not:

(a)  request any present  customers or suppliers of the WSB or any  customers of
     Buyer or any  affiliates  of Buyer  ("Buyer's  Affiliates")  to  curtail or
     cancel their business with Buyer (or Buyer's Affiliates);

(b)  disclose  to any  person,  firm or  corporation  any  trade,  technical  or
     technological  secrets of or any  details of the  organization  or business
     affairs of the WSB; or

(c)  induce or actively  attempt to influence  any employee of Buyer (or Buyer's
     Affiliates) to terminate his or her employment.

Seller and Parent agree that if either the length of time or  geographical  area
as set  forth in this  Section  11.04 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
11.04 are in addition to any other  obligations  that Seller and Parent may have
under the laws of any state  requiring  a  corporation  selling its assets (or a
shareholder  of such  corporation)  to limit its activities so that the goodwill
and business relations being transferred with such assets will not be materially
impaired.   Seller  and  Parent  further  acknowledge  that  Buyer  and  Buyer's
Affiliates  do not have any adequate  remedy at law for the breach or threatened
breach by Seller or Parent of the covenants contained in this Section 11.04, 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  Seller or Parent  from such
breach or threatened breach. If any provisions of this Section 11.04 are held to
be invalid or against  public policy,  the remaining  provisions of this Section
11.04 and the  Agreement  shall  not be  affected  thereby.  Seller  and  Parent
acknowledge  that the  covenants  set  forth in this  Section  11.04  are  being
executed and  delivered by such party in  consideration  of (i) the covenants of
Buyer contained in this Agreement,  (ii) the Non-Compete  Payment, and (iii) for
other good and  valuable  consideration,  the receipt  and  adequacy of which is
hereby acknowledged.

                                   ARTICLE XII

     such default, and, if it is so cured, Buyer shall, for that reason, have no
     right to terminate this Agreement;

(c)  by  Seller,  if  notice  has been  given to  Buyer of the  occurrence  of a

     been waived in writing; provided,  however, that Buyer shall, after receipt
     of such notice, have a period of twenty (20) business days in which to cure
     such default,  and, if it is so cured,  Seller shall, for that reason, have
     no right to terminate this Agreement; or

(d)  by any party  hereto if the  Closing  shall not have  occurred on or before
     November 1, 1998; provided,  however,  that any termination by a defaulting
     party  shall not  affect any rights  that a  non-defaulting  party may have
     against such defaulting party.

Section 12.02.  Effect of  Termination.  In the event of the termination of this
Agreement by either party in  accordance  with the  provisions  of Section 12.01
hereof,  this Agreement  shall become void and have no force or effect,  without
any  liability  on  the  part  of any  party  hereto  (or  its  stockholders  or
controlling  persons or directors or officers)  and with each party  bearing its
own expenses as incurred;  provided,  however,  that if such  termination is the
result of the  non-terminating  party having breached (i) its obligations  under
Section 6.04 or 7.05 hereof,  as  applicable,  or (ii) any of its other material
representations,  warranties,  covenants  or  agreement  contained  herein,  the
terminating party shall have the right to issue all remedies  available to it at
law or in equity as a result of such  breach  (including  reasonable  attorney's
fees and expenses incurred in connection with enforcing such remedies).

                                  ARTICLE XIII

                                  MISCELLANEOUS

Section 13.01.  Interpretive  Provisions.  For purposes of this  Agreement,  the
phrase "to the  knowledge"  and any other  phrases  generally  referring  to the
knowledge  of a party  hereto,  shall mean the actual  knowledge of such party's
officers  or  of  such  party's  managerial  and  supervisory  personnel  having

section of this  Agreement and all  references to a "Schedule" shall refer to a
Schedule attached hereto unless otherwise stated.

Section 13.06.  Entire  Agreement.  This  Agreement  (including  the  documents,
schedules,  attachments,  exhibits,  annexes and instruments referred to herein)
constitutes  the entire  agreement  between the parties and supersedes all prior
agreements,  documents or other  instruments with respect to the matters covered
hereby. The parties will make, and have made, no oral agreements or undertakings
pertaining to the subject matter of this  Agreement,  except for any that are no

(a) extend the time for the  performance of any of the obligations or other acts
of the other party or (b) waive  compliance  with any of the  agreements  of the

unenforceable  provision with a valid and enforceable provision that places each

provision been valid and enforceable.

shall not be  assignable  nor the  duties  delegable  by any party  without  the
written  consent of the other party,  which  consent  shall not be  unreasonably
withheld;  provided,  however, that Buyer may assign the rights to a subsidiary;
provided,  further,  that such assignment  shall not affect Buyer's  obligations
hereunder.  This Agreement shall be binding upon and inure solely to the benefit
of each of the parties hereto and their permitted  assigns,  and nothing in this
Agreement,  express or implied,  is intended to confer upon any other person any
rights  or  remedies  of any  nature  whatsoever  under  or by  reason  of  this
Agreement.  Nothing in this Agreement shall be construed to create any rights or
obligations  except among the parties  hereto,  and no person or entity shall be
regarded as a third-party beneficiary of this Agreement.

Section 13.12.  Governing Law. THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED

JURISDICTION,  WHEREIN  THE ASSETS  ARE  LOCATED,  SHALL  APPLY,  EXCLUDING  THE
CONFLICT OF LAWS RULES OF SUCH STATE.

Section 13.13.  Specific  Performance.  Buyer and  Seller  each agree  that,  in
addition to the other legal  remedies  provided by the terms of this  Agreement,
