     Article I
                         Representations and Warranties

     Article I.1 Representations and Warranties of Seller. Seller represents and
     warrants to
     Buyer as follows:

     Article I.1.1. Organization and Good Standing. 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 except where the failure to
     make such qualification would not have a material adverse effect on Seller.

     Article I.1.1. Agreements Authorized and their Effect on Other Obligations.
     The execution and delivery of this  Agreement  have been  authorized by all
     necessary  corporate,  shareholder  and other action on the part of Seller,
     and  this  Agreement  is  the  valid  and  binding   obligation  of  Seller
     enforceable  (subject to normal  equitable  principals)  against  Seller 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 Seller, (ii) any
     obligation,  indenture,  mortgage,  deed of trust, lease, contract or other
     agreement to which  Seller is a party or by which Seller or its  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 Seller or any of its properties are subject.
 
     2.1.3  Contracts.  Schedule 1.1(d) hereto sets forth a complete list of all
     contracts,  including  leases under which Seller is lessor or lessee,  that
     relate to the conduct of the Business or the  ownership or operation of the
     Assets and are to be performed in whole or in part after the Closing  Date.
     All of the Contracts are in full force and effect and constitute  valid and
     binding  obligations  of Seller.  Seller is not,  and to the  knowledge  of
     Seller,  no other party to any of the Contracts is, in default  thereunder,
     and to the  knowledge  of  Seller,  no event has  occurred  which  (with or
     without  notice,  lapse of time, or the happening of any other event) would
     constitute a default thereunder. No Contract has been entered into on terms
     which could  reasonably be expected to have an adverse effect on the use of
     the Assets by Buyer.  Seller has not  received any  definitive  information
     which would cause Seller to conclude that any customer of Seller related to
     the Business  representing  more than ten (10%)  percent of Seller's  total
     revenue  from the  Business  for the fiscal year of Seller  ended April 30,
     1998  will (or is  likely  to)  cease  doing  business  with  Buyer (or its
     successors)  as  a  result  of  the   consummation   of  the   transactions
     contemplated  hereby.  All of the Contracts are assignable  (and are hereby
     validly assigned) to Buyer without the consent of any other party thereto.

     2.1.4 Title to and Condition of Assets.  Seller has good,  indefeasible and
     marketable  title to all of the Assets,  free and clear of any Encumbrances
     (defined below). Assets are being transferred as is, where is. Seller makes
     no warranties as to general  condition or fitness for a particular  purpose
     or  otherwise  regarding  the  condition  of the Assets  save and except as
     provided in this Agreement. No notice of any violation of any law, statute,
     ordinance, or regulation relating to any of the Assets has been received by
     Seller or any director,  officer, or shareholder of Seller,  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.

     2.1.5  Licenses and Permits.  Schedule  1.1(e) hereto sets forth a complete
     list of all Permits necessary under law or otherwise for the conduct of the
     Business and the ownership, operation, maintenance and use of the Assets in
     the manner in which the Business is currently  being  conducted  and in the
     manner in which the Assets are now being  operated,  maintained  and used .
     Each of the Seller  Permits and  Seller's  rights with  respect  thereto is
     valid and subsisting,  in full force and effect,  and enforceable by Seller
     subject   to   administrative   powers  of   regulatory   agencies   having
     jurisdiction.  Seller is in  compliance  in all material  respects with the
     terms of each of the Seller  Permits.  None of the Seller Permits has been,
     or to the  knowledge of Seller are  threatened  to be,  revoked,  canceled,
     suspended or modified.  Upon consummation of the transactions  contemplated
     hereby,  all of the  Seller  Permits  shall be  assignable  (and are hereby
     assigned)  to Buyer  without  the consent of any  regulatory  agency or any
     other  third  party.  On and after the  Closing  Date,  each of the  Seller
     Permits  and  Buyer's  rights  with  respect  thereto  will  be  valid  and
     subsisting in full force and effect,  and enforceable by Buyer subject only
     to the  administrative  powers of regulatory  agencies having  jurisdiction
     over the applicable Seller Permit.

     2.1.6  Financial  Information.  Seller  has  delivered  to Buyer  copies of
     certain financial information of Seller related to the Business,  copies of
     which are  attached  hereto as Schedule  2.1.6  (collectively,  the "Seller
     Financial Information"), and include a "Gross Margin Statement" as of March
     31, 1998 (the "Statement Date"). The Seller Financial  Information is true,
     correct and complete in all material respects and presents fairly and fully
     such  financial  information  of the  Business  for the  periods  indicated
     thereon.  The inventories of Seller, which have thereafter been acquired by
     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  consistent  with the normal  inventory  level and practices of
     Seller with respect to the Business.
 
     2.1.7  Absence of Certain  Changes and Events.  Since the  Statement  Date,
     there has not been: (a) Financial Change.  Any adverse change in the Assets
     or the Business or prospects of the Business;

     mortgage,  pledge or other  encumbrance  of any of the Assets other than in
     the ordinary course of business;

     Employees, as defined in Section 3.2 hereof; or

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

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

     2.1.9 Environmental  Matters. None of the current or past operations of the
     Business,  any of the  Assets or the Land,  as that term is defined in that
     certain  Real  Estate   Purchase   Agreement  (the  "Real  Estate  Purchase
     Agreement")  between Charley R. Smith and Julee W. Smith, as Co-Trustees of
     the Charley and Julee Smith Living Trust (the "Smith Trust") and Charley R.
     Smith and Julee W.  Smith,  individually  (the "Trustors"),  dated May 19,
     1998,  is  being  or has  been  conducted  or used in such a  manner  as to
     constitute a violation of any Environmental Law (defined below).  Except as
     disclosed  on Schedule  2.1.9  hereto  Seller has not  received  any notice
     (whether formal or informal, written or oral) from any entity, governmental
     agency  or  individual  regarding  any  existing,   pending  or  threatened
     investigation or inquiry related to violations of any  Environmental Law or
     regarding any claims for remedial  obligations or contribution  for removal
     costs  or  damages  under  any  Environmental  Law.  There  are  no  writs,
     injunction decrees, orders or judgments outstanding,  or lawsuits,  claims,
     proceedings  or  investigations  pending or, to the  knowledge  of Seller ,
     threatened relating to the ownership,  use, maintenance or operation of the
     Assets,  the conduct of the Business or the Land,  nor, to the knowledge of
     Seller, is there any basis for any of the foregoing.  Buyer is not required
     to obtain any permits,  licenses or similar authorizations  pursuant to any
     Environmental  Law in effect as of the Closing  Date to operate and use any
     of the  Assets for their  current or  proposed  purposes  and uses.  To the
     knowledge of Seller,  the Assets  include all  environmental  and pollution
     control  equipment  necessary for compliance with applicable  Environmental
     Law. No  Hazardous  Materials  (defined  below) have been or are  currently
     being used by Seller in the  operation  of the Assets,  the Business or the
     Land. No Hazardous Materials are or have ever been situated on or under the
     Land,  or  incorporated  into any of the Assets.  There are no  underground
     storage tanks (as defined under  Environmental Law) currently located under
     the Land, and any underground  storage tanks previously located on or under
     the Land have been removed in compliance with all applicable  Environmental
     Law. There are no environmental conditions or circumstances,  including the
     presence or release of any Hazardous  Materials,  on any property presently
     or previously  owned or leased by Seller related to the Business or Assets,
     including  but not  limited  to,  the  Land,  or on any  property  on which
     Hazardous Materials generated by Seller's operations of the Business or the
     use of the Assets were disposed of, which would result in an adverse change
     in the Assets, the Business or business prospects of the Business. The term
     Environmental  Law means any and all laws,  rules,  orders,  regulations,
     statutes,   ordinances,  codes,  decrees,  and  other  legally  enforceable
     requirements  (including,  without  limitation,  common  law) of the United
     States,  or  any  state,   regional,   city,  local,   municipal  or  other
     governmental   authority  or  quasi-governmental   authority,   regulating,
     relating  to, or imposing  environmental  standards  of conduct  concerning
     protection  of the  environment  or human  health,  or employee  health and
     safety  as from  time to  time  has  been  or is now in  effect.  The  term
     "Hazardous Materials" means (x) asbestos,  polychlorinated  biphenyls, urea
     formaldehyde,  lead based paint,  radon gas,  petroleum,  oil, solid waste,
     pollutants and contaminants,  and (y) any chemicals,  materials,  wastes or
     substances that are defined,  regulated,  determined or identified as toxic
     or hazardous in any Environmental Law.

     2.1.10 No ERISA Plans or Labor Issues.  No employee benefit plan of 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.  Seller has not engaged in
     any unfair labor practices which could  reasonably be expected to result in
     an adverse effect on the Assets.  Seller does not have any dispute with any
     of the  Employees  or any of its former  employees,  and there are no labor
     disputes or, to the knowledge of Seller, any disputes threatened by current
     or former  employees  of Seller  which would have an adverse  effect on the
     Assets or the Business.

     2.1.11  Investigations;  Litigation.  No  investigation  or  review  by any
     governmental  entity  with  respect  to Seller  or any of the  transactions
     contemplated  by this  Agreement is pending or, to the knowledge of Seller,
     threatened,  nor  has  any  governmental  entity  indicated  to  Seller  an
     intention  to  conduct  the  same.  There is no  suit,  action,  or  legal,
     administrative,   arbitration,   or  other   proceeding   or   governmental
     investigation pending to which Seller is a party or might become a party or
     any other  unasserted  claims  against  Seller  which would have an adverse
     effect on the Assets or the Business.

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

     2.1.13  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
     secured or unsecured.

     2.1.14 Untrue Statements.  This Agreement and all other agreements executed

     Montana,  North Dakota,  Utah,  Nebraska,  and South Dakota, as well as the
     area which is within a 25 mile radius  from the city limits of  Farmington,
     New Mexico (collectively,  the "Territories") which would be in competition
     with any of the Business conducted by Buyer or any affiliate of Buyer; (ii)
     request any  customers or  suppliers of Buyer or any  affiliate of Buyer to
     curtail  or  cancel  any of  their  Business  conducted  with  Buyer or any
     affiliate of Buyer;  (iii) disclose to any person,  firm or corporation any
     trade,  technical or  technological  secrets of the Business other than any
     such  information  which  relates to the  Excluded  Business,  or any other
     business  of  Buyer or any  affiliate  of  Buyer  or any  details  of their
     organization  or business  affairs not  otherwise  available  in the public
     domain;  or (iv) induce or actively  attempt to influence any Employee,  as
     hereinafter  defined,  or an Employee of Buyer or any affiliate of Buyer to

     Buyer in the  Territories  desires to utilize  the  services of Seller from
     facilities outside the Territories during the Noncompetition Period, such a
     transaction  will not be in violation of this  Section 3.1.  Seller  agrees
     that if either  the length of time or  geographical  area set forth in this
     Section 3.1 is deemed too restrictive in any court  proceeding,  such court
     may reduce such  restrictions to those which it deems  reasonable under the
     circumstances.  Seller further agrees and  acknowledges  that the Buyer and
     its  affiliates  do not have any  adequate  remedy at law for the breach or
     threatened breach by Seller of this covenant,  and agrees that the Buyer or
     any affiliate of Buyer may, in addition to the other  remedies which may be
     available to it hereunder, file a suit in equity to enjoin Seller 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.  Seller  acknowledges that the covenants set forth in
     this  Section  3.1  are  being   executed   and   delivered  by  Seller  in
     consideration  of the covenants of Buyer contained in this  Agreement,  and
     for  other  good and  valuable  consideration,  receipt  of which is hereby
     acknowledged.
 
     3.2  Hiring  Employees.  Schedule  3.2 hereto is a  complete  and  accurate
     listing of certain  employees  of Seller  that  devote  their full time and
     effort in the conduct of the Business  (the  "Employees").  Effective as of
     the Closing Date, all of the Employees shall be offered employment by Buyer
     subject to such Employees meeting Buyer's standard  employment  eligibility
     requirements.  Buyer shall have no liability or obligation  with respect to
     any employee  benefits of any Employee  except those  benefits  that accrue
     pursuant to such  Employees'  employment with Buyer on or after the Closing
     Date . Seller 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.  Seller  acknowledges  its
     understanding  that it is Buyer's intent that all Employees  hired by Buyer
     shall be at-will employees of Buyer.  Buyer agrees that as to each Employee
     hired by Buyer that such  Employee  shall be hired at each such  Employee's
     respective  current  salary with credit for prior service with Seller as it
     relates to compensation and benefit plans of Buyer.

     3. 3 Allocation of Purchase  Price of Assets.  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 Closing Date .

     3.4 Real  Estate  Purchase.  Concurrent  with the  execution  and  delivery
     hereof,  the Smith Trust and Buyer shall have  entered into the Real Estate
     Purchase Agreement (and consummated the transactions  contemplated thereby)
     pursuant  to which the Smith  Trust  will have  conveyed  to Buyer the real
     property owned by the Smith Trust described on Schedule 3.4 hereto.

     3.5 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.

     3.6 Use of Name.  Seller  consents to the use of the name "Watson  Oilfield
     Service  &  Supply,  Inc."  (or  a  substantially   similar  name)  in  the
     Territories. Seller agrees to execute any and all instruments, certificates
     or other  documents  and take any and all  action  as may be  necessary  or
     appropriate of Seller for Buyer to use such name in the Territories.  Buyer
     agrees that prior to a change in control of Buyer that Buyer  shall  obtain
     the written  consent of Seller to the continued use of the name "Watson Oil
     Field  Service & Supply,  Inc." by  Buyer,  or change  the name of Buyer to
     delete the use of the name  "Watson." For purposes of this Section 3.6, the
     term "control"  shall be ownership of voting rights of not less than 70% of
     the voting  rights  related to all issued  and  outstanding  securities  of
     Buyer.  Additionally,  Buyer  agrees that it will not sell or transfer  the
     name "Watson Oilfield Service & Supply,  Inc." (or a substantially  similar
     name containing the name "Watson") to a non-affiliate  of Buyer without the
     prior written consent of Seller."
     3.7 Use of Watson Hopper  Blueprints.  Seller  agrees to make  available to
     Buyer and allow Buyer to use the blueprints and other technical information
     necessary  for Buyer to conduct the  Business for the term and any renewals
     and extensions of the Watson Hopper Distribution Agreement.

     3.8  Guaranty  by Seller of  Indemnification  under  Real  Estate  Purchase
     Agreement.  Seller  agrees to and  hereby  unconditionally  guarantees  the
     performance of any and all  indemnifications  and  obligations of the Smith
     Trust or the Trustors under the terms of the Real Estate Purchase Agreement
     (the  "Guaranty").  Seller  waives  notice of any  amendments,  changes  or
     modifications  to the Real Estate  Purchase  Agreement or any agreements or
     obligations  of any of the  parties to the Real Estate  Purchase  Agreement
     which  survive  the  Closing  (as that term is defined  in the Real  Estate
     Purchase Agreement and the use of the term "Closing" as defined in the Real
     Estate  Purchase  Agreement  shall be limited  to use only in this  Section
     3.8). Seller further expressly waives notice of non-payment,  protest,  and
     notice of protest with respect to the indebtedness and obligations  covered
     by the Guaranty.  It shall not be necessary for Buyer,  in order to enforce
     payment by Seller under the Guaranty,  to first institute suit or to pursue
     or exhaust its  remedies  against  either the Smith Trust or the  Trustors.
     Seller agrees that this Guaranty  shall  continue in full force and effect,
     notwithstanding  the  termination of the Smith Trust or the death of either
     of the  Trustors or the release by  agreement or by operation of law or the
     extension of time to the Smith Trust or either of the Trustors as to any of
     their obligations then existing. Seller acknowledges that the covenants set
     forth in this Section 3.8 are being delivered by Seller in consideration of

     valuable consideration, receipt of which is hereby acknowledged.
 
     Article I

     other  remedies  available to Buyer under this  Agreement,  or at law or in
     equity,  Seller shall  indemnify,  defend and hold  harmless  Buyer and its
     affiliates,   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  (whether  the  Damages  are  suffered  or  incurred  by a Buyer
     Indemnified  Party  directly or as a result of a third party claim  against
     such Buyer Indemnified  Party),  which arise,  result from or relate to (i)
     any  breach  of, or  failure  by Seller to  perform,  its  representations,
     warranties,  covenants or agreements in this  Agreement or in any schedule,
     certificate, exhibit or other instrument furnished or delivered to Buyer by
     Seller  under this  Agreement or (ii) the  Retained  Liabilities,  provided
     however, that (x) Seller shall not be required to so indemnify,  defend and
     hold harmless  Buyer against and with respect to any Damages  incurred as a
     result of a breach by Seller of its  representations and warranties in this
     Agreement,  or in any schedule,  certificate,  exhibit or other  instrument
     furnished or delivered  by Seller to Buyer under this  Agreement  for which
     Buyer fails to provide written notice of a claim for such damages to Seller
     on or before the  expiration  of the  survival  period.  (As  specified  in
     Section 6.1 hereof) of the specific  representation  or warranty alleged to
     have been  breached,  and (y) Seller shall not be required to so indemnify,
     defend and hold harmless Buyer unless and until the Damages equal or exceed
     $25,000 in the aggregate (the "Indemnification  Threshold"),  at which time
     Seller shall  indemnify,  defend and hold  harmless  Buyer for all Damages,
     including  but not limited to those  Damages less than the  Indemnification
     Threshold.

     Article I.1  Indemnification  by Buyer.  In addition to any other  remedies
     available to Seller  under this  Agreement,  or at law or in equity,  Buyer
     shall  indemnify,  defend and hold harmless Seller against and with respect
     to any and all Damages that such indemnitees  shall incur or suffer,  which
     arise,  result  from or relate to (i) any breach of, or failure by Buyer to
     perform, any of its representations, warranties, covenants or agreements in
     this Agreement or in any schedule, certificate, exhibit or other instrument
     furnished  or  delivered  to Seller by or on  behalf  of Buyer  under  this
     Agreement, (ii) the Assumed Liabilities, or (iii) except to the extent that
     any  Damages  arise  out of a breach  by  Seller  of any of its  respective
     representations,  warranties  or covenants  contained  herein,  the Buyer's
     conduct  of the  Business  after the  Closing  Date save and except for the
     Retained  Liabilities,  provided  however,  that  (x)  Buyer  shall  not be
     required to so indemnify,  defend and hold harmless Seller against and with
     respect  to any  Damages  incurred  as a result of a breach by Buyer of its
     representations  and  warranties  in  this  Agreement  or in any  schedule,
     certificate,  exhibit, or other instrument  furnished or delivered by Buyer
     to Seller under this  Agreement  for which Seller fails to provide  written
     notice of a claim for such Damages to Buyer on or before the  expiration of
     the survival  period (as specified in Section 6.1 hereof),  of the specific
     representation  or warranty  alleged to have been  breached,  and (y) Buyer
     shall not be  required to so  indemnify,  defend and hold  harmless  Seller
     unless and until the Damages equal or exceed  $25,000 in the aggregate (the
     "Indemnification  Threshold"),  at which time Buyer shall indemnify, defend
     and hold harmless  Seller for all Damages,  including  but not limited,  to
     those Damages less than the Indemnification Threshold.

     Article I.1  Indemnification  Procedure.  If any party hereto  discovers or
     otherwise becomes aware of an  indemnification  claim arising under Section
     4.1 or 4.2 of this  Agreement,  such  indemnified  party shall give written
     notice to the indemnifying party, specifying such claim, and may thereafter
     exercise  any  remedies  available  to such  party  under  this  Agreement;
     provided, however, that the failure of any indemnified party to give notice
     as  provided  herein  shall  not  relieve  the  indemnifying  party  of any
     obligations  hereunder,  to  the  extent  the  indemnifying  party  is  not
     materially  prejudiced  thereby.  Further,  promptly  after  receipt  by an
     indemnified  party  hereunder of written notice of the  commencement of any
     third  party  action or  proceeding  against  such  indemnified  party 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 third party 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 third party 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 third  party  claim and to
     employ counsel  reasonably  satisfactory  to such  indemnified  person.  An
     indemnifying  party who elects not to assume the  defense of a third  party
     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 third party claim or with respect
     to  third  party  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 third
     party 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 third  party  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 third party  claimant or  plaintiff to such  indemnified  party of a
     release  from all  liability  with  respect to such third party  claim.  No
     indemnified  party shall consent to entry of any judgment or enter into any
     settlement  of any such third party  action,  the defense of which has been
     assumed by an indemnifying party,  without the consent of such indemnifying
     party, which consent shall not be unreasonably withheld or delayed.
