                                    Article I

                           Purchase and Sale of Assets

cashier's check or bank check or wire transfer of immediately available funds to
an account or accounts designated by the Seller.

                                   Article II

                         Representations and Warranties
                        of the Seller and the Shareholder

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

II.1.1.  Organization  and Good  Standing.  The  Seller  is a  corporation  duly
organized,  validly existing and in good standing under the laws of its state of
organization,  has full requisite  corporate power and authority to carry on its
business as it is  currently  conducted,  and to own and operate the  properties
currently  owned and  operated  by it, and is duly  qualified  or licensed to do
business  and is in good  standing  as a foreign  corporation  authorized  to do
business in all  jurisdictions in which the character of the properties owned or
the nature of the  business  conducted  by it would make such  qualification  or
licensing necessary.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

II.1.12.  Absence of Certain  Business  Practices.  Neither the Seller,  nor any
officer of the Seller, nor to the best of Seller's knowledge,  employee or agent
of the Seller, or any other person acting on behalf of any of the Seller,  have,
directly or indirectly,  within the past five years, given or agreed to give any
gift or similar benefit to any customer, supplier,  government employee or other
person who is or may be in a position  to help or hinder the  profitable  use of
the Assets (or to assist the Seller in  connection  with any actual or  proposed
transaction)  which if not given in the past,  might have had a material adverse
effect on the profitable  use of the Assets,  or if not continued in the future,
might materially adversely affect the profitable use of the Assets.

II.1.13. Solvency. The Seller is not presently insolvent, nor will the Seller be
rendered  insolvent by the occurrence of the  transactions  contemplated by this
Agreement. The term "insolvent", with respect to a particular Seller, means that
the sum of the present fair and saleable value of such Seller's  assets does not
and will not  exceed  its  debts and other  probable  liabilities,  and the term
"debts" includes any legal liability whether matured or unmatured, liquidated or
unliquidated, absolute fixed or contingent, disputed or undisputed or secured or
unsecured.

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

II.1.15.  Finder's  Fee. All  negotiations  relative to this  Agreement  and the
transactions  contemplated  hereby  have  been  carried  on by the  Seller,  the
Shareholder and their counsel  directly with Buyer and its counsel,  without the
intervention  of any other  person  in such  manner as to give rise to any valid
claim against any of the parties hereto for a brokerage commission, finder's fee
or any similar payment.

                                   Article III

                              Additional Agreements

III.1 Noncompetition. Except as otherwise consented to or approved in writing by
Buyer,  each of the  Seller  and the  Shareholder  agree that for a period of 60
months following the date hereof,  such party will not,  directly or indirectly,
acting alone or as a member of a  partnership  or a holder of, or investor in as
much as 5% of any  security of any class of any  corporation  or other  business
entity (i) engage in any business in competition with the business or businesses
conducted  by the Seller on the date hereof or by Buyer (or Buyer's  affiliates)
on the date  hereof,  or in any  service  business  the  services  of which  are
provided  and  marketed by the Seller on the date hereof or by Buyer (or Buyer's
affiliates) on the date hereof in the following states: West Virginia, Virginia,
Kentucky,   Ohio,   Pennsylvania,   New  York,   Maryland   and   Indiana   (the
"Non-Competition Territory"); (ii) request any present customers or suppliers of
the Seller to curtail or cancel their business with Buyer; (iii) disclose to any
person,  firm or corporation any trade,  technical or  technological  secrets of
Buyer  (or  Buyer's  affiliates)  or of the  Seller  or  any  details  of  their
organization or business affairs or (iv) induce or actively attempt to influence
any employee of Buyer (or Buyer's affiliates) to terminate his employment. Buyer
acknowledges that Seller owns oil and gas wells and is engaged in the production
of oil and gas  therefrom.  Nothing  contained  herein  shall  be  construed  to
prohibit  Seller or  Shareholder  from  continuing to engage in said oil and gas
production within the Non-Competition Territory and from servicing only such oil
and gas wells owned by Seller or Shareholder;  provided  however that Seller and
Shareholder agree that any equipment acquired or leased by Seller or Shareholder
for the purpose of servicing Seller or Shareholder's  oil and gas wells shall be
used exclusively for the purpose of servicing Seller or Shareholder's  wells and
not for wells  owned by others or for  compensation.  Each of the Seller and the
Shareholder  agree that if either the length of time or geographical area as set
forth in this Section 3.1 is deemed too restrictive in any court proceeding, the
court may reduce such  restrictions to those which it deems reasonable under the
circumstances.  The obligations expressed in this Section 3.1 are in addition to
any other  obligations  that the Seller and the  Shareholder  may have under the
laws  of  any  state  requiring  a  corporation  selling  its  assets  (and  the
shareholders  of such  corporation) to limit its activities so that the goodwill
and business relations being transferred with such assets will not be materially
impaired.  Each of the Seller and the Shareholder  further agree and acknowledge
that Buyer does not have any adequate remedy at law for the breach or threatened
breach by the  Seller or the  Shareholder  of the  covenants  contained  in this
Section 3.1, and agree that Buyer may, in addition to the other  remedies  which
may be available to it hereunder,  file a suit in equity to enjoin the Seller or
the Shareholder from such breach or threatened breach. If any provisions of this
Section  3.1 are held to be invalid  or against  public  policy,  the  remaining
provisions shall not be affected thereby. Each of the Seller and the Shareholder
acknowledges that the covenants set forth in this Section 3.1 are being executed
and delivered by such party in consideration of the covenants of Buyer contained
in this Agreement, and for other good and valuable consideration, the receipt of
which is hereby acknowledged.

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

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

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

III.5 Further Assurances.  From time to time, as and when requested by any party
hereto,  any other  party  hereto  shall  execute  and  deliver,  or cause to be
executed and delivered,  such documents and instruments and shall take, or cause
to be taken,  such further or other  actions as may be  reasonably  necessary to
effect the transactions contemplated hereby.

                                   Article IV

                                 Indemnification

IV.1 Indemnification by the Seller and the Shareholder. In addition to any other
remedies available to Buyer under this Agreement,  or at law or in equity,  each
of the Seller and the  Shareholder  shall,  jointly  and  severally,  indemnify,
defend and hold harmless Buyer and its officers,  directors,  employees,  agents
and  stockholders,  against  and  with  respect  to any and all  claims,  costs,
damages, losses, expenses, obligations,  liabilities,  recoveries, suits, causes
of  action  and  deficiencies,  including  interest,  penalties  and  reasonable
attorneys' fees and expenses (collectively,  the "Damages") that such indemnitee
shall incur or suffer,  which arise, result from or relate to (i) any breach of,
or failure by either the Seller or the Shareholder to perform,  their respective
representations, warranties, covenants or agreements in this Agreement or in any
schedule,  certificate,  exhibit or other  instrument  furnished or delivered to
Buyer by the Seller or the Shareholder under this Agreement; and (ii) the Seller
Liabilities.

IV.2  Indemnification  Procedure.  If any party  hereto  discovers  or otherwise
becomes  aware of an  indemnification  claim  arising  under Section 4.1 of this
Agreement,  such indemnified party shall give written notice to the indemnifying
party, specifying such claim, and may thereafter exercise any remedies available
to such party under this Agreement;  provided,  however, that the failure of any
indemnified  party to give  notice as  provided  herein  shall not  relieve  the
indemnifying party of any obligations hereunder,  to the extent the indemnifying
party is not materially prejudiced thereby.  Further,  promptly after receipt by
an  indemnified  party  hereunder of written notice of the  commencement  of any
action or proceeding  with respect to which a claim for  indemnification  may be
made  pursuant to this Article 4, such  indemnified  party shall,  if a claim in
respect  thereof is to be made  against any  indemnifying  party,  give  written
notice to the latter of the commencement of such action; provided, however, that
the failure of any indemnified party to give notice as provided herein shall not
relieve the indemnifying party of any obligations  hereunder,  to the extent the
indemnifying party is not materially prejudiced thereby. In case any such action
is  brought  against an  indemnified  party,  the  indemnifying  party  shall be
entitled to participate in and to assume the defense  thereof,  jointly with any
other  indemnifying  party similarly  notified,  to the extent that it may wish,
with counsel  reasonably  satisfactory to such indemnified party, and after such
notice from the indemnifying  party to such indemnified party of its election so
to assume the defense  thereof,  the  indemnifying  party shall not be liable to
such indemnified party for any legal or other expenses  subsequently incurred by
the latter in connection with the defense thereof unless the indemnifying  party
has failed to assume the defense of such claim and to employ counsel  reasonably
satisfactory to such indemnified person. An indemnifying party who elects not to
assume the defense of a claim  shall not be liable for the fees and  expenses of
more than one counsel in any single  jurisdiction for all parties indemnified by
such  indemnifying  party with  respect to such claim or with  respect to claims
separate but similar or related in the same jurisdiction arising out of the same
general allegations.  Notwithstanding any of the foregoing to the contrary,  the
indemnified  party will be  entitled  to select its own  counsel  and assume the
defense of any action  brought  against it if the  indemnifying  party  fails to
select counsel reasonably satisfactory to the indemnified party, the expenses of
such defense to be paid by the indemnifying  party. No indemnifying  party shall
consent to entry of any judgment or enter into any settlement  with respect to a
claim without the consent of the indemnified  party,  which consent shall not be
unreasonably  withheld,  or unless such  judgment or  settlement  includes as an
unconditional  term  thereof  the giving by the  claimant or  plaintiff  to such
indemnified party of a release from all liability with respect to such claim. No
indemnified  party  shall  consent  to entry of any  judgment  or enter into any
settlement  of any such  action,  the  defense  of which has been  assumed by an
indemnifying  party,  without  the  consent of such  indemnifying  party,  which
consent shall not be unreasonably withheld.

                                    Article V

                                  Miscellaneous

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

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

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