contemplated changes in the status of the zoning for the Real Property. There is
no agreement  currently in effect  between  Seller and the county or township in

binding  and  would  prevent  the use of the Real  Property  for any of the uses
allowed by the  current  zoning of the Real  Property,  and Seller does not have

owner of the Real Property.

       4.6  Agreement  Does Not Violate Other  Instruments.  Except as listed in
Schedule 4.6, the  execution  and delivery of this  Agreement by the Seller does
not,  and the  consummation  of the  transaction  contemplated  hereby will not,
violate any  provision  of the  Certificate  of  Incorporation,  as amended,  or
Bylaws,  as amended,  of the Seller or violate or  constitute  an  occurrence of
default under any provision of, or conflict with, or result in  acceleration  of
any  obligation  under,  or give rise to a right by any party to  terminate  its
obligations under, any mortgage, deed of trust, conveyance to secure debt, note,
loan, lien,  lease,  agreement,  instrument,  order,  judgment,  decree or other
arrangement  to which the  Seller is a party or is bound or by which the  Assets
are  affected.  Except as listed or  described  on  Schedule  4.6,  no  consent,
approval,  order or  authorization  of, or  registration,  declaration or filing
with,  any  governmental  entity is  required  to be obtained or made by or with
respect to Seller or any of the Assets,  properties or operations of the Seller,
in connection with the execution and delivery by Seller of this Agreement or any
of the agreements,  certificates or other documents delivered or to be delivered
on or after the date  hereof and at or prior to the Closing in  connection  with
the transactions contemplated hereby.

               V. Income, Debts, Liabilities, Transitional Matters

       5.1 Purchaser's Responsibilities.  Purchaser shall be responsible for and
shall  pay only the debts  and  liabilities  incurred  in the  operation  of the
Business  subsequent  to the  Effective  Date,  except as  specifically  assumed
hereunder  by  Seller.  Except as  specifically  assumed  by  Seller  hereunder,
Purchaser hereby  indemnifies the Seller from all liabilities and obligations to
third parties arising from operation of the Business subsequent to the Effective
Date including,  without limitation,  any of the following: any indebtedness for
borrowed  money,  any liability  for taxes,  any liability for goods or services
purchased, sold or rendered, or any suit or claim seeking recovery for injury to
persons or property  resulting  from any product or service  sold or rendered by
Purchaser subsequent to the Effective Date, plus reasonable attorney fees.

       5.2 Seller's Responsibilities.  Except as specifically assumed hereunder,
Purchaser  shall not assume or become liable to Seller,  or to any other person,
firm, corporation or entity, for any other liabilities or obligations of Seller,
whether  accrued,  absolute,  contingent  or otherwise.  Except as  specifically
assumed by Purchaser hereunder, Seller hereby indemnifies the Purchaser from all
liabilities  and  obligations  to third  parties  arising from  operation of the
Business prior to the Effective Date including,  without limitation,  any of the
following:  any  indebtedness  for borrowed money,  any liability for taxes, any
liability for goods or services purchased, sold or






rendered,  or any suit or claim  seeking  recovery  for  injury  to  persons  or
property  resulting from any product or service sold or rendered by Seller prior
to the Effective Date, plus reasonable  attorney fees.  Nothing contained herein
shall be deemed a waiver or release by  Purchaser of amounts due from Seller for
services  rendered  prior to the Effective  Date.  Unless  specifically  assumed
herein,  the fact that a matter or  contract  is listed on a  Schedule  does not
imply or mean that Purchaser assumes responsibility therefore.


       5.3 Transition Period Matters. Notwithstanding the foregoing Sections 5.1
and 5.2, the following  govern the operation of and  accounting for the Business
between the Effective Date and Closing (the "Transition Period").

           5.3.1  Transitional  Period Operations During the Transition  Period,
Seller shall use its best efforts to operate the Business in the Ordinary Course
of  Business,  which  shall be defined as  operation  of Seller's  short  radius
directional   drilling  business  and  survey  business  without   extraordinary
occurrences or  expenditures.  By way of example,  and not by way of limitation,
the following would be matters  outside of the Ordinary  Course of Business:  an
accident  involving  personal injury, an accident  involving  property damage in
excess of $50,000,  purchase of equipment  having a purchase  price in excess of
$25,000,  and improper  performance of services for a customer resulting in loss
to the customer of more than $50,000.  Should there occur, during the Transition
Period,  a matter  outside the Ordinary  Course of  Business,  Seller shall give
notice thereof to Purchaser prior to Closing.  In an effort to reduce the impact
of any matter outside the Ordinary Course of Business,  Seller hereby  transfers
to  Purchaser  Seller's  rights to  proceeds  from any claims  paid by  Seller's
insurers with respect to claims arising from  occurrences  during the Transition
Period.

           5.3.2 Transition Period Accounting . At Closing, Seller shall deliver
to  Purchaser  a  statement  of income  and  expense  for the  Business  for the
Transition Period,  calculated in in the format and containing the specific line
items set forth in Schedule 5.3.2 (the "Transition Operating Statement"). Seller
shall pay to  Purchaser  at Closing the  "Operating  Profit" as set forth on the
Transition Operating Statement. In preparing the Transition Operating Statement,
the following principals shall apply:

                 5.3.2.1  Income  shall be  calculated  by taking the sum of all
revenue  billed by Seller  during  the  Transition  Period,  less  billings  for
services rendered prior to the Effective Date;

                 5.3.2.2 which shall then be reduced by the  following  expenses
incurred and accrued on the books of Seller during the  Transition  Period:  (i)
direct,  out of pocket cash  Expenses and (ii) the non-cash  expenses  listed on
Schedule 5.3.2.2,

                 5.3.2.3  which shall then be increased by a Motor Repair Charge
with respect to all motors  engaged in jobs in progress on the Effective Date (a
"Job in  Progress"),  which Motor  Repair  Charge shall be, with respect to each
such  motor,  the number of hours such motor was run on a Job in Progress at $45
per hour prior to the Effective Date; and

                 5.3.2.4  Seller  shall  allocate  common  expenses  in a manner
consistent  with practices  historically  followed  during the period October 1,
1997 through  November 30, 1997,  with the  exception  that Seller may charge an
expense interest allocation at the rate of 6% for one-half of the number of days
in the Transition Period on $19 Million, which interest charge shall .be in lieu
of any other interest charge, and Seller shall not charge depreciation.






       If Purchaser  objects to Seller's  calculation  of the Operating  Profit,
Purchaser and Seller shall submit the Transition  Operating Statement to Coopers
& Lybrand,  or such  other  mutually  acceptable  accounting  firm,  for a final
determination  of  the  Operating  Profit,  following  which  determination  any
difference shall be paid by the party owing same.

       5.4 Certain  Receivables.  Receivables  arising  from  revenue  billed by
Seller during the Transition Period and listed on Schedule 5.3.2 shall belong to
Seller. Receivables arising from services performed from and after the Effective
Date but not  billed by Seller  during the  Transition  Period  shall  belong to
Purchaser.  Each party shall retain possession of and be solely  responsible for
collecting all accounts  receivable  attributable to invoices  generated by such
party;  provided,  however,  that the parties agree to reasonably cooperate with
one another in the collection of the accounts receivable.

standing as a foreign  corporation  in all  jurisdictions  required for it to do
business,  and  neither the  character  of the  property  owned or leased by the

by the Purchaser in connection  herewith,  constitute or will, when executed and

and enforceable  against  Purchaser in accordance with their  respective  terms,
except as enforceability may be limited by applicable equitable principles or by
bankruptcy, insolvency, reorganization,  moratorium or similar laws from time to
time in effect affecting the enforcement of creditors' rights generally.  Except
as listed or described on Schedule 6.2 attached  hereto,  no consent,  approval,

the agreements,  certificates or other documents delivered or to be delivered on
or after the date hereof and at or prior to the Closing in  connection  with the

Material Adverse Effect.

Schedule  6.3, the execution  and delivery of this  Agreement by Purchaser  does
not,  and the  consummation  of the  transaction  contemplated  hereby will not,
violate any  provision  of the  Certificate  of  Incorporation,  as amended,  or
Bylaws,  as amended,  of Purchaser or violate or  constitute  an  occurrence  of
default under any provision of, or conflict with, or result in  acceleration  of
any  obligation  under,  or give rise to a right by any party to  terminate  its
obligations under, any mortgage, deed of trust, conveyance to secure debt, note,
loan, lien, lease, agreement, instrument,






or any order,  judgment,  decree or other  arrangement  to which  Purchaser is a
party or is bound by or by which the  Assets are  affected.  Except as listed or
described on Schedule 6.3, no consent,  approval,  order or authorization of, or
registration, declaration or filing with, any governmental entity is required to
be  obtained  or made by or with  respect  to  Purchaser  or any of the  Assets,

delivery by Purchaser of this Agreement or any of the  agreements,  certificates
or other documents  delivered or to be delivered on or after the date hereof and
at or prior to the  Closing in  connection  with the  transactions  contemplated
hereby.

       6.4 No  Known  Breaches.  Purchaser  has  no  knowledge  that  any of the
representations  or  warranties  of Seller are  untrue.  Purchaser  shall not be
entitled to indemnification with respect to any matters constituting a breach of
this Section 6.4.

       9.3 Accounting Commitments by Seller.


           9.3.1.  Seller shall provide to Purchaser or its  representatives all
commercially   reasonable   support  to  facilitate  the  preparation  by  Price

six accounting  firm chosen by Purchaser (the  "Auditors")  for inclusion of the

Exchange Commission (the "SEC").  Seller's commitment to provide support is with
the  understanding  that the  Carve-Out  Audit is  scheduled  to be completed by
January 31, 1998,  and Seller  agrees to use its best efforts to cooperate  with
such schedule. If the Auditors determine that Purchaser should include prior






audits of the Acquisitions, previously performed for Seller by Price Waterhouse,
in any SEC filing by Purchaser,  Seller will comply with all reasonable requests
of the Auditors relating to such consent,  and will use commercially  reasonable
efforts to obtain the consent of Price Waterhouse.

           9.3.2.  Seller  acknowledges  its  understanding  that Purchaser will
audit The  Business  for the year ended  December  31, 1997 (the "1997  Audit").

audit,  in  order  to  complete  same  prior to  March  1,  1998  (the  "Support
Obligation").  During and after the audit process,  Seller or Seller's  officers
shall  execute  such  management  representation  letters  as may be  reasonably
requested by the Auditors (the "Representation  Obligation").  It is agreed that

industry.  Seller (on behalf of RSS) and  Purchaser  shall  negotiate,  prior to
Closing, a marketing agreement,  which will provide that Purchaser's  Multi-Shot
division  shall be the sole  user to test run the  prototype  or  pre-commercial
pilot tools within North America, provided that Purchaser is able to secure such
testing  facilities  without  undue  delay or  disruption  to  Seller's  testing
schedule,  until the system is deemed  commercial by Seller.  At an  appropriate
time  during the testing  program,  but not more than ninety days prior to first

       9.6 Claims Procedures.

           9.6.1 Third Party Claims.

                 9.6.1.1 Notification and Defense Rights.

                         (i) If any person entitled to indemnification  pursuant
to this Agreement (an "Indemnitee")  receives written notice of the assertion of
any claim or of the  commencement  of any action or proceeding by any entity who
is not a party to this  Agreement (a "Third Party  Claim")  against or affecting
such Indemnitee, and if such assertion were presumed






to be true (regardless of the actual  outcome),  then the other party or parties
could  be  obligated  to  provide   indemnification  under  this  Agreement  (an
"Indemnifying  Party"),  then such Indemnitee will give such Indemnifying  Party
reasonably prompt written notice thereof,  but in any event no later than thirty
(30)  calendar  days after  receipt of such  written  notice of such Third Party
Claim.  However, if it is reasonably determined by the Indemnitee that immediate
action is required to address a  condition  giving rise to a Third Party  Claim,
the Indemnitee is authorized to take immediate action without prior notice,  and
thereafter give notice to the Indemnifying Party as soon as practicable. In such
event the Indemnitee shall be entitled to recover from the Indemnifying Party to
the extent the Indemnifying Party is liable for indemnification hereunder.

                         (ii)  Failure  of the  Indemnitee  to give  the  notice
described in subsection (i) above shall not relieve the Indemnifying  Party from
any  liability  which it may have on account of  indemnification  or  otherwise,
except to the extent that the Indemnifying Party is prejudiced thereby.

                         (iii) If the Indemnifying Party admits in the Notice to
Defend  (defined below) its obligation to indemnity the Indemnitee for the Third
Party Claim, and only in such event, the Indemnifying  Party may elect to defend
the Third Party Claim at the  Indemnifying  Party's sole expense by Indemnifying
Party's  own counsel  (which  counsel  must be  reasonably  satisfactory  to the
Indemnitee), by giving written notice to the Indemnitee (the "Notice to Defend")
no later than twenty (20)  calendar  days after  receipt of the  above-described
notice of such Third Party  Claim.  The  Indemnitee  also will have the right to
participate  in the defense of any Third Party Claim assisted by counsel of this
own choosing;

                         (iv) In all circumstances  other than that described in
subsection  (iii) above,  the  Indemnifying  Party may  participate  in (but not
control)  the  defense  if it gives the  notice to of its desire to do so within
such twenty-day period,  provided,  however,  that the Indemnitee shall have the
sole right to make any significant decisions with respect to the defense of such
Third Party Claim except as to the  settlement or compromise of such Third Party
Claim which shall be subject to the provisions of Section 9.6.1.2.

                         (v) During the period prior to receiving  the Notice to
Defend, the Indemnitee can proceed to defend the claim, action or proceeding and
the Indemnitee shall be entitled to recover from the  Indemnifying  Party to the
extent the  Indemnifying  Party is liable for  indemnification  hereunder.  (vi)
Notwithstanding   anything  in  this  Section  9.6.1.1  to  the  contrary,   the
Indemnifying  Party shall be entitled only to participate in, but the Indemnitee
shall be entitled to sole and absolute  control over the defense,  compromise or
settlement  of, any claim to the extent  that the claim seeks an  injunction  or
other similar equitable or nonmonetary relief against the Indemnitee.

                         (vii) If the  Indemnitee  does not  receive a Notice to
Defend  with  respect  to a Third  Party  Claim  within  the  twenty  day period
described in subsection (iii) above,  the Indemnitee may, at its option,  solely
defend the Third Party Claim  assisted by counsel of its own  choosing,  and the
Indemnifying Party will be liable for all reasonable costs and expenses, and all
settlement  amounts  (subject to and in accordance with Sections  9.6.1.2),  but
only  to the  extent  the  Indemnifying  Party  is  liable  for  indemnification
hereunder.

                         (viii) Notwithstanding the foregoing, in the event that
an insurer has  assumed  the  defense of any Third  Party Claim  pursuant to the
terms of an insurance  policy,  then the parties agree,  subject to the terms of
such policy, to let the counsel of such insurance company conduct the defense of
such Third Party Claim and both the Indemnifying Party and the




Indemnitee  shall have the right to  participate  in the defense and (subject to
Section 9.6.1.2(vi)) hereof settlement of such Third Party Claim.

                 9.6.1.2 Settlement.

                         (i)  In  the   circumstances   described   in   Section
9.6.1.1(iii)  where the  Indemnifying  Party has the sole right to  control  the
defense of the Third Party  Claim,  the  Indemnifying  Party shall have the sole
right to settle such  claim.  Furthermore,  in the  circumstances  described  in
Section 9.6.1.1(vi),  the Indemnitee shall have the sole right to settle a Third
Party Claim to the extent provided in such Section.

                         (ii) In all other circumstances,  if there is a dispute
between the Indemnifying  Party and Indemnitee  concerning whether a Third Party
Claim,  should  be  contested,  settled  or  compromised,  it shall be  settled,
compromised or contested,  in accordance with the next succeeding subsections of
this Section 9.6.1.2; provided,  however, that the Indemnitee, or its respective
successors  or assigns,  shall  neither be  required  to refrain  from paying or
satisfying  any claim  which the  Indemnifying  Party  has not  acknowledged  in
writing its  obligations  to indemnify the  Indemnitee,  or which has matured by
court  judgment or decree,  unless appeal is taken  thereafter and proper appeal
bond posted by the  Indemnifying  Party, nor shall the Indemnitee be required to
refrain from paying or satisfying  any Third Party Claim after and to the extent
that such Third Party Claim has  resulted  in an  unstayed  injunction  or other
similar equitable relief against the Indemnitee or its respective successors and
assigns  (unless such claim shall have been  discharged or  enforcement  thereof
stayed by the filing of a legally  permitted bond by the  Indemnifying  Party or
otherwise,  at its sole  expense),  or  resulted  in a breach  or  default  in a
license,  lease  or  other  contract  by which  any of them is  bound,  or would
materially  adversely  affect their respective  assets,  businesses or financial
condition.

                         (iii)  Subject to subsection  (ii) of this Section,  in
the event that the  Indemnifying  Party, on the one hand, or the Indemnitee,  on
the other hand,  has reached a good faith,  bona fide  settlement  agreement  or
compromise,  subject only to approval  hereunder,  with any claimant regarding a
matter  which may be the  subject of  indemnification  hereunder  and desires to
settle on the basis of such agreement or  compromise,  such party who desires to
settle or  compromise  shall  notify  the other  party in  writing of its desire
setting  forth  the terms of such  settlement  or  compromise  (the  "Notice  of
Settlement").

                         (iv)  The  Third   Party   Claim  may  be   settled  or
compromised  on the basis set forth in the Notice of  Settlement  unless  within
twenty (20) days of the receipt of the Notice of Settlement the party who issued
the Notice of Settlement receives a notice from the other party of its desire to
continue to contest the matter (the "Notice of Contest") and, in such case:

                               (a)  Should  the  Indemnitee  deliver a Notice of
Contest,  the claim shall be so contested and the liability of the  Indemnifying
Party shall be limited as provided in subsection (c) below.

                               (b) If the settlement or compromise  could result
in a claim for indemnification  being made against the Indemnifying Party and if
the  Indemnifying  Party  delivers the Notice to Contest,  the claim shall be so
contested  and the liability of the  Indemnitee  shall be limited as provided in
subsection (c) below.

                               (c) If a  matter  is  contested  as  provided  in
subsections (a) or (b) above and is later adjudicated,  settled,  compromised or
otherwise disposed of and such




adjudication, compromise, settlement or disposition results in a liability loss,
damage or injury in excess of the amount for which one party desired  previously
to  settle  the  matter  as set  forth in the  Notice  of  Settlement,  then the
liability  of such party  shall be limited to such  lesser  proposed  settlement
amount and the party  contesting the matter shall be solely  responsible for the
amount in excess of such lessor proposed settlement amount and without regard to
any minimum or maximum restriction on liability described in the Agreement.

                         (v) For an Indemnifying Party's Notice of Contest to be
effective,  it must also  state that the  Indemnifying  Party  acknowledges  and
agrees that it shall be obligated to indemnify the  Indemnitee for any amount in
excess of the lesser  proposed  settlement  amount as  described  in  subsection
(iv)(c) above.

                         (vi) The Indemnifying Party hereby expressly waives and
renounces  any and all  rights to make a claim  against  the  Indemnitee  or its
respective directors,  officer, agents and employees based upon a right or claim
of any third party to which it may become  subrogated  as a result of making any
payment  for  indemnification  hereunder,  except to the extent that such waiver
adversely  affects any rights of  subrogation  of an insurer under an applicable
insurance policy; provided,  however, nothing herein is intended to constitute a
waiver by the Indemnifying Party of any rights of subrogation to which it may be
entitled against persons other than those described herein.

           9.6.2 Direct Claims.  Any claim by an Indemnitee for  indemnification
other than  indemnification  against a Third Party Claim (a "Direct Claim") will
be asserted by giving the Indemnifying  Party  reasonably  prompt written notice
thereof,  and the Indemnifying  Party will have a period of thirty (30) calendar
days  within  which  to  respond  in  writing  to  such  Direct  Claim.  If  the
Indemnifying  Party does not so respond  within such thirty  (30)  calendar  day
period,  the  Indemnifying  Party will be deemed to have rejected such claim, in
which event the Indemnitee will be free to pursue such remedies as are set forth
in Section 9.6.3 hereof.

           9.6.3 Direct Claim Procedures.

                 (a) Any Direct  Claim  which the  parties are unable to resolve
through  negotiation within sixty (60) day's notice to the Indemnifying Party of
such Direct Claim (a "Dispute")  shall be settled by  arbitration  in accordance
with the Commercial  Arbitration Rules of the American  Arbitration  Association
(the  "Association"),  as the same are to be supplemented  hereunder,  by a sole
arbitrator.  The  decision  of  the  arbitrator  shall  be  final,  binding  and
conclusive and judgment upon the award rendered by the arbitrator may be entered
in any court or appropriate jurisdiction. With respect to such arbitration:

           (i) the  arbitration  proceeding  shall be held in the  Association's
office in Houston,  Texas, or in such other location as is mutually agreeable to
the parties and the arbitrator.

           (ii) the parties agree to use their best efforts,  in good faith,  to
select  a  sole  arbitrator  qualified  to  act as an  arbitrator  based  on the
underlying  nature of the  Dispute.  Such  arbitrator  shall be selected  within
twenty  (20)  business  days  after  either  party  requests  arbitration.  Upon
selection,  the  arbitrator's  name,  address  and  telephone  number  shall  be
forwarded  to the  Association's  office  in  Houston,  Texas,  as  part  of the
arbitration process.

           (iii) the arbitrator is specifically  instructed to allow the parties
reasonable  discovery  and to be guided  therein by the  Federal  Rules of Civil
Procedure.  If the arbitrator is not an attorney, or is an attorney not familiar
with the Federal Rules of Civil






Procedure,  and the  parties  cannot  agree  among  themselves  with  respect to
discovery,  the  arbitrator  may  consult  an  attorney  and  the  cost  of such
consultation to the arbitrator shall be an additional cost of the arbitration.

           (iv) once an arbitrator has been selected,  each party shall submit a
statement of the case  detailing  the nature of the  Dispute,  the basis for the
position  taken by the party,  that party's  understanding  of the basis for the
position  taken by the other  party,  legal  authority  believed  to govern  the
Dispute,  a list of the exhibits and witnesses  known to the party at that point
in time, and a request for discovery.

           (v) after the date of selection of an  arbitrator,  the parties shall
have a period not to exceed  sixty (60) days to conduct  discovery as each deems
appropriate.  Once the discovery period has closed,  either by expiration of the
time limit or by mutual agreement of the parties, the arbitrator and the parties
shall mutually agree upon a date to hold the arbitration  proceeding,  said date
not to be more than  thirty (30) days after the close of the  discovery  period.
Prior to commencement of the arbitration  proceeding,  each party shall serve an
amended  statement  of the case,  updating the material set forth in the party's
original  statement of the case,  and  including  the list of witnesses who will
testify,  with a brief  summation  of the  testimony  of such  witnesses;  which
amended brief shall not exceed ten double  spaced pages of text without  written
waiver first being received from the arbitrator.

           (vi) each party shall equally pay the fees charged by the Association
including  any fee to be paid to the  arbitrator,  and any cost  incurred by the
arbitrator as allowed by the Rules of the American Arbitration  Association,  or
this Section 9.6.3. In addition, in the award the arbitrator shall specify which
of the parties is the prevailing  party, and the prevailing party shall receive,
as an additional  part of the award,  his/their/its  reasonable  attorneys fees,
costs and expenses incurred in connection with the arbitration  proceeding in an
amount deemed  appropriate by the arbitrator  based on the comparative  fault of
the parties.  The amount of fees and costs shall be based upon an affidavit from
legal counsel of each party,  submitted as part of the  arbitration  proceeding,
setting forth in chronological order the dates legal services were rendered, the
amount of time  within  each day  devoted  to this  proceeding,  the name of the
individual attorney, paralegal and other assistants and his or her billing rate,
and a list of  out-of-pocket  costs or expenses  incurred.  The arbitrator shall
take into account the additional time involved in the arbitration hearing itself
when considering an award of reasonable attorneys fees.

       9.7 Indemnification by Seller

           9.7.1   Indemnification  by  Seller  Regarding   Representations  and
Warranties, Survival of Same.

              .      4.3.1
              .      4.3.2
              .      4.3.3

              .      4.20
              .      4.21.


       The  representations  and warranties set forth in the following  sections
shall  survive  Closing  hereunder  for two  years,  and  shall not merge in the
performance of any obligation by any party hereto:


              .      4.1
              .      4.2
              .      4.3.5, except with respect to the balance sheet warranty

              .      4.23
              .      4.24

Subject to the foregoing,  and to Section 9.9, Seller hereby agrees to indemnify
and hold Purchaser and its officers, directors, employees, attorneys, agents and
other representatives harmless from and against and in respect of any liability,
claim,  deficiency,  loss,  damages,  or  injury  and all  reasonable  costs and
expenses  (including  reasonable  attorneys  fees and  cost of any suit  related
thereto)  suffered or incurred by such person  (collectively,  a "Loss") arising
from any breach of any  representation  or warranty of the Seller which survives
Closing,  or any exhibit,  certificate  or other  instrument  furnished or to be
furnished by the Seller  pursuant to such  representation  or  warranty,  or any
Third Party Claim (regardless of whether the claimant is ultimately  successful)
which if true would be such a misrepresentation  or breach.  Notwithstanding the
foregoing,  the Seller  shall not be required  to  indemnify  Purchaser  for any
liability, loss, damage or injury to the extent Purchaser receives proceeds from
any insurance policies purchased by Seller or Purchaser; provided, however, that
if an  insurer  denies  payment  of a  claim  under  such an  insurance  policy,
Purchaser  shall be  entitled  to  indemnification  from the Seller and shall be
under no obligation to pursue any action against such insurer.

           9.7.2 Survival of Covenants and Agreements.

       All covenants and agreements  undertaken by the Seller in Articles II, V,
VII, IX and X of this Agreement or in any in any document or instrument executed
and  delivered   pursuant  thereto   ("Seller's   Covenants"),   are  continuing
obligations  of  Seller,  which  survive  Closing,  and are not  subject  to the
limitations of Section 9.9.

       9.8 Indemnification by Purchaser




           9.8.1  Indemnification  by Purchaser  Regarding  Representations  and
                  Warranties, Survival of Same.

       All representations and warranties made or undertaken by the Purchaser in
this Agreement or in any document or instrument  executed and delivered pursuant
hereto are material and have been relied upon by Seller. The representations and
warranties  of  Purchaser  set forth in Sections  6.1 through 6.5 shall  survive
Closing  hereunder for two years,  and shall not merge in the performance of any
obligation by any party hereto.  Subject to the  foregoing,  and to Section 9.9,
Purchaser  hereby  agrees  to  indemnify  and  hold  Seller  and  its  officers,
directors,  employees, attorneys, agents and other representatives harmless from
and against and in respect of any liability, claim, deficiency, loss, damage, or
injury and all reasonable  costs and expenses  (including  reasonable  attorneys
fees and cost of any suit related  thereto)  suffered or incurred by such person
(collectively,  a  "Loss")  arising  from any  breach of any  representation  or
warranty of the Purchaser which survives Closing, or any exhibit, certificate or
other instrument  furnished or to be furnished by the Purchaser pursuant to such
representation or warranty,  or any Third Party Claim (regardless of whether the
claimant   is   ultimately   successful)   which   if  true   would  be  such  a
misrepresentation or breach.  Notwithstanding the foregoing, the Purchaser shall
not be required to indemnify Seller for any liability, loss, damage or injury to
the extent Seller  receives  proceeds from any insurance  policies  purchased by
Seller or Purchaser;  provided,  however, that if an insurer denies payment of a
claim   under  such  an   insurance   policy,   Seller   shall  be  entitled  to
indemnification  from the  Purchaser  and shall be under no obligation to pursue
any action against such insurer.

           9.8.2 Survival of Covenants and Agreements.

       All covenants and agreements  undertaken by the Purchaser in Articles II,
V, VII and IX of this Agreement or in any in any document or instrument executed
and  delivered  pursuant  thereto  ("Purchaser's  Covenants"),   are  continuing
obligations  of  Purchaser,  which survive  Closing,  and are not subject to the
limitations of Section 9.9.

       9.9 Calculation of and Limitation on Indemnification.

           9.9.1  Calculation.  Subject  to the  limitations  imposed by Section
9.9.2  below,  for purposes of this Article IX only,  in  determining  whether a
representation  or warranty of a party has been  violated  or  breached,  and in
calculating  the amount of claims  relating  to such  violation  or breach,  the
standards of Materiality and Material Adverse Effect shall be disregarded.

           9.9.2 Limitation.  Notwithstanding any other provisions  contained in
this  Article IX, with the  exception of Sections  9.7.2 and 9.8.2,  (i) neither
Purchaser  nor Seller shall be entitled to receive any amount under this Article
IX which exceeds the Purchase  Price;  (ii)  Purchaser  shall not be entitled to
payment  under this  Article IX except for the amount by which the  aggregate of
all claims for Losses  hereunder,  which have not theretofore been reimbursed to
Purchaser,  exceeds the sum of $500,000 (provided,  however, that any claim with
respect to the Credit shall not be subject to this limitation); and (iii) Seller
shall not be entitled to payment  under this Article IX except for the amount by
which  the  aggregate  of  all  claims  for  Losses  hereunder  which  have  not
theretofore been reimbursed to Seller exceeds the sum of $500,000.

           9.9.3  Example.  By way of example  and not by  limitation,  if it is
determined  that  Seller  did not have  clear  title to a portion  of the Assets
resulting  in a Loss of  $250,000,  that the  Business is subject to a claim for
patent infringement resulting in a Loss of $270,000, then Purchaser would have a
claim under this Article IX of $20,000, notwithstanding the fact that,





considered   separately,   neither  item  reaches  the  economic   standard  for
Materiality.

       9.10 Sole Basis For Recovery.  Unless specifically provided for elsewhere
in this Agreement, the parties intend this Article IX to be the exclusive method
for  compensating  each other for, or  indemnifying  each other against,  claims
relating to the Transactions.

       9.11 West Little  York Lease.  Seller and  Purchaser  shall,  at Closing,
execute a lease on the West  Little  York Lease  Parcel,  through the earlier of
September 1, 1998 or the date of completion of the  Purchaser's  new facility in
Conroe, Texas, in the form attached as Schedule 8.5.

       9.12 Cooperation  Regarding  Collection of Receivables.  Each party shall
retain  possession  of and be solely  responsible  for  collecting  all accounts
receivable attributable to invoices generated by such party; provided,  however,
that  the  parties  agree  to  reasonably  cooperate  with  one  another  in the
collection of the accounts receivable.

                          X. Non-Competition Agreement

       10.1 For a period  of five  years  following  Closing  (the  "Non-Compete
Period"),  neither Seller nor any Affiliate (as defined in Section 10.2,  below)
shall directly or indirectly own, operate,  manage, or engage in the directional
drilling  services  business or the survey services  business in North and South
America,  and the surrounding  offshore waters (the "Non-Compete  Area"),  which
area is deemed  reasonable  by the  parties  considering  the present and former
areas  where  Seller and its  predecessors  by  acquisition  or merger have done
business.  The foregoing  sentence  shall not be deemed to have been violated by
the manufacturing and sales business of PEPI (including RSS), nor by the leasing
business of PEPI (including  RSS),  providing that said leasing  business is not
the  equivalent  of  engaging  in the  directional  drilling  services or survey
services  business.  The parties desire to comply with the Texas Covenant Not to
Compete Act.  Should the Non-Compete  Area or the  Non-Compete  Period be deemed
overly broad,  then the parties  hereby agree that same shall be reduced,  by an
appropriate authority, to a period or area deemed reasonable.

       10.2 As  used  herein,  "Affiliate"  shall  mean  Seller,  together  with
Seller's ultimate parent,  Phoenix Energy Services,  L.L.C.  ("Energy"),  or any
direct or indirect subsidiary of Seller or Energy, whether or not wholly owned.

       10.3 It is agreed by the parties  hereto that, in the event of any breach
of the non-competition provisions of this Agreement, legal remedies available to
the  Purchaser  would be  inadequate.  Therefore,  in the event of such  breach,
notwithstanding the Arbitration provisions hereof, the Purchaser is specifically
authorized to apply to a court of competent jurisdiction to enjoin any violation
of such provision.

                                XI. Miscellaneous

       11.1 No Assignment.  Neither this Agreement,  nor any right,  interest or
obligation  hereunder,  may be assigned by either of the parties  hereto without
the prior  written  consent of the other  party(s),  except that  Purchaser  may
assign this  Agreement,  in whole or in part, to its  subsidiary  Boone Wireline
Co.,  Inc.,  provided that no such  assignment  shall  relieve  Purchaser of any
obligations created hereunder.

       11.2 Multiple 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 and the same agreement,  binding
on both the parties  notwithstanding  that both parties have not signed the same
counterpart.

       11.5 Entire  Agreement,  Integration.  This Agreement,  together with the
accompanying  schedules  which are attached  hereto and  incorporated  herein by
reference,  constitutes  the entire  agreement  among the parties  hereto,  as a
complete  and  final  integration  thereof.  All  understandings  and  agreement
heretofore  had between and among the parties with respect to the subject matter
of this  Agreement  are  merged  into  this  Agreement,  which  alone  fully and
completely  expresses their  understandings,  and this Agreement  supersedes all
prior memoranda, correspondence, conversations and negotiations.

       There  have been and are no  agreements,  representations  or  warranties
between the parties other than those set forth or provided herein.

       No representation or warranty made by any party which is not contained in
this  Agreement or expressly  referred to herein has been relied on by any party
in entering into this Agreement.

hereunder  shall be in  writing  and shall be deemed to have been duly given and

jurisdiction  shall construe and interpret this Agreement to provide for maximum
