WHEREAS,  the Sellers desire to sell certain assets to Buyer,  and Buyer desires

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

                                    Article I

                           Purchase and Sale of Assets

forth in this  Agreement,  the Sellers hereby agree to sell,  convey,  transfer,
assign and deliver to Buyer all of the assets  more  particularly  described  on
Schedule  I.1 hereof  (all such  assets  being sold  hereunder  are  referred to
collectively herein as the "Assets"):

Sellers  shall  execute  and  deliver  to Buyer  Bills  of Sale  and  Assignment
conveying all of Sellers'  respective right, title and interest in the Assets to

                                   Article II

                         Representations and Warranties
                                 of the Sellers

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

II.1.1. Organization and Good Standing.  Petro-Equipment,  Inc. is a corporation
duly  organized,  validly  existing and in good  standing  under the laws of its
state of organization, has full requisite corporate power and authority to carry
on its  business  as it is  currently  conducted,  and to own  and  operate  the
properties currently owned and operated by it.

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

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

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

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

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

II.1.7. Solvency.  Neither Seller is presently insolvent, nor will either Seller
be rendered insolvent by the occurrence of the transactions contemplated by this
Agreement. The term "insolvent", with respect to a particular Seller, means that
the sum of the present fair and saleable value of such Seller's  assets does not
and will not  exceed  its  debts and other  probable  liabilities,  and the term
"debts" includes any legal liability whether matured or unmatured, liquidated or
unliquidated, absolute fixed or contingent, disputed or undisputed or secured or
unsecured.

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

II.1.9.  Finder's  Fee.  All  negotiations  relative to this  Agreement  and the
transactions  contemplated  hereby have been carried on by the Sellers and their
counsel  directly with Buyer and its counsel,  without the  intervention  of any
other  person in such manner as to give rise to any valid  claim  against any of
the  parties  hereto for a  brokerage  commission,  finder's  fee or any similar
payment.

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

                                   Article III

                              Additional Agreements

III.1 Noncompetition. Except as otherwise consented to or approved in writing by
Buyer,  each of the Sellers and William  Patrick Burr agree that for a period of
60  months  following  the  date  hereof,  such  party  will  not,  directly  or
indirectly,  acting  alone or as a member of a  partnership  or a holder  of, or
investor  in as much as 5% of any  security of any class of any  corporation  or
other business entity (i) engage in any business providing logging,  perforating
or electric  wireline services or own, operate or lease a complete service truck
for use in the well  service or  wireline  service  business  in West  Virginia,
Virginia,  Kentucky,  Ohio,  Pennsylvania,  New York,  Maryland and Indiana (the
"Non-Competition Territory"); (ii) request any present customers or suppliers of
Young  Wireline  Services,  Inc. or  customers  or  suppliers  of the Sellers to
curtail or cancel their business with Buyer; (iii) disclose to any person,  firm
or  corporation  any  trade,  technical  or  technological  secrets of Buyer (or
Buyer's  affiliates) or of the Sellers or any details of their  organization  or
business affairs or (iv) induce or actively attempt to influence any employee of
Buyer (or Buyer's  affiliates) to terminate his employment;  provided,  however,
that nothing  contained herein shall be construed to prevent Sellers from owning
Superior  Micro System and  continuing to operate  Superior  Micro System in the
businesses  in which it is operated as of the date hereof,  nor shall Sellers be
prevented  from leasing a complete  full service  truck to a competitor of Buyer
who has been in existence for at least five years prior to the date hereof for a
lease term not to exceed  ninety (90) days,  which lease term cannot be extended
or  renewed,  provided  such  business  is not owned by any former  employee  of
Hitwell Surveys,  Inc., Young Wireline Service,  Inc., or Titan Surveys. Each of
the Sellers and William Patrick Burr agrees that if either the length of time or
geographical  area as set forth in this Section III.1 is deemed too  restrictive
in any court  proceeding,  the court may reduce such restrictions to those which
it deems  reasonable  under the  circumstances.  Each of the Sellers and William
Patrick  Burr  further  agrees  and  acknowledges  that  Buyer does not have any
adequate  remedy at law for the breach or  threatened  breach by the  Sellers or
William Patrick Burr of the covenants contained in this Section III.1, and agree
that Buyer may, in addition to the other  remedies  which may be available to it
hereunder,  file a suit in equity to enjoin the Sellers or William  Patrick Burr
from such breach or threatened  breach.  If any provisions of this Section III.1
are held to be invalid or against public policy, the remaining  provisions shall
not  be  affected  thereby.  Each  of  the  Sellers  and  William  Patrick  Burr
acknowledges  that the  covenants  set  forth in this  Section  III.1  are being
executed and delivered by such party in  consideration of the covenants of Buyer
contained in this Agreement, and for other good and valuable consideration,  the
receipt of which is hereby acknowledged.

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

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

III.4 Further Assurances.  From time to time, as and when requested by any party
hereto,  any other  party  hereto  shall  execute  and  deliver,  or cause to be
executed and delivered,  such documents and instruments and shall take, or cause
to be taken,  such further or other  actions as may be  reasonably  necessary to
effect  the  transactions  contemplated  hereby,  including  but not  limited to
certificates of title to any of the Assets which were not delivered at Closing.


                                   Article IV

                                 Indemnification

IV.1 Indemnification by the Sellers. In addition to any other remedies available
to Buyer  under  this  Agreement,  or at law or in equity,  each of the  Sellers
shall, jointly and severally,  indemnify, defend and hold harmless Buyer and its
officers,  directors,  employees,  agents  and  stockholders,  against  and with
respect to any and all claims, costs, damages,  losses,  expenses,  obligations,
liabilities,  recoveries,  suits,  causes of action and deficiencies,  including
interest,  penalties and reasonable attorneys' fees and expenses  (collectively,
the "Damages") that such indemnitee shall incur or suffer,  which arise,  result
from or relate to any breach of, or failure by either of the Sellers to perform,
their respective  representations,  warranties,  covenants or agreements in this
Agreement or in any schedule, certificate, exhibit or other instrument furnished
or delivered to Buyer by the Sellers under this  Agreement;  provided,  however,
that such  indemnity,  including  claims for breach of  warranty of title to the
Assets, shall not exceed the Purchase Price. Donald E. Clark ("Clark") expressly
assumes  and agrees to  indemnify  Buyer for any claim for  Damages  asserted by
Buyer hereunder  against Clark or against  Petro-Equipment,  Inc.. Clark further
agrees that Buyer may assert any claim for  indemnity  against  Petro-Equipment,
Inc.  directly against Clark without first asserting or exhausting any remedies,
it may have against  Petro-Equipment,  Inc.,  provided  that Clark's  Indemnity,
including  claims for breach of warranty of title to the Assets shall not exceed
the Purchase Price.

IV.2  Indemnification  Procedure.  If any party  hereto  discovers  or otherwise
becomes  aware of an  indemnification  claim  arising under Section IV.1 of this
Agreement,  such indemnified party shall give written notice to the indemnifying
party, specifying such claim, and may thereafter exercise any remedies available
to such party under this Agreement;  provided,  however, that the failure of any
indemnified  party to give  notice as  provided  herein  shall not  relieve  the
indemnifying party of any obligations hereunder,  to the extent the indemnifying
party is not materially prejudiced thereby.  Further,  promptly after receipt by
an  indemnified  party  hereunder of written notice of the  commencement  of any
action or proceeding  with respect to which a claim for  indemnification  may be
made pursuant to this Article IV, such  indemnified  party shall,  if a claim in
respect  thereof is to be made  against any  indemnifying  party,  give  written
notice to the latter of the commencement of such action; provided, however, that
the failure of any indemnified party to give notice as provided herein shall not
relieve the indemnifying party of any obligations  hereunder,  to the extent the
indemnifying party is not materially prejudiced thereby. In case any such action
is  brought  against an  indemnified  party,  the  indemnifying  party  shall be
entitled to participate in and to assume the defense  thereof,  jointly with any
other  indemnifying  party similarly  notified,  to the extent that it may wish,
with counsel  reasonably  satisfactory to such indemnified party, and after such
notice from the indemnifying  party to such indemnified party of its election so
to assume the defense  thereof,  the  indemnifying  party shall not be liable to
such indemnified party for any legal or other expenses  subsequently incurred by
the latter in connection with the defense thereof unless the indemnifying  party
has failed to assume the defense of such claim and to employ counsel  reasonably
satisfactory to such indemnified person. An indemnifying party who elects not to
assume the defense of a claim  shall not be liable for the fees and  expenses of
more than one counsel in any single  jurisdiction for all parties indemnified by
such  indemnifying  party with  respect to such claim or with  respect to claims
separate but similar or related in the same jurisdiction arising out of the same
general allegations.  Notwithstanding any of the foregoing to the contrary,  the
indemnified  party will be  entitled  to select its own  counsel  and assume the
defense of any action  brought  against it if the  indemnifying  party  fails to
select counsel reasonably satisfactory to the indemnified party, the expenses of
such defense to be paid by the indemnifying  party. No indemnifying  party shall
consent to entry of any judgment or enter into any settlement  with respect to a
claim without the consent of the indemnified  party,  which consent shall not be
unreasonably  withheld,  or unless such  judgment or  settlement  includes as an
unconditional  term  thereof  the giving by the  claimant or  plaintiff  to such
indemnified party of a release from all liability with respect to such claim. No
indemnified  party  shall  consent  to entry of any  judgment  or enter into any
settlement  of any such  action,  the  defense  of which has been  assumed by an
indemnifying  party,  without  the  consent of such  indemnifying  party,  which
consent shall not be unreasonably withheld.

                                    Article V

                                  Miscellaneous

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

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

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

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