     listed on Schedule 1.1(b) all of which are referred to in this Agreement as
     the "Excluded Assets."

A.   Agreement to Purchase. At the Closing,  Purchaser shall purchase the Assets
     from the  Sellers  upon and  subject  to the terms and  conditions  of this
     Agreement and in reliance on the representations,  warranties and covenants
     of the Sellers  contained  herein,  in exchange for the Purchase  Price (as
     defined in Section 1.3). In addition, Purchaser shall assume, and DPS shall
     cause  Purchaser to assume,  at the Closing and agree to pay,  discharge or
     perform,  as  appropriate,  certain  liabilities  and  obligations  of  the
     Sellers,  but only to the extent expressly  provided in Section 1.4. Except
     as  expressly  provided in Section  1.4,  Purchaser  shall not assume or be
     responsible  for any liabilities or obligations  based on events  occurring
     prior to Closing relative to the Assets, the Business or the Sellers.

                       A. The Purchase Price; Tax Basis.

(a)  The Purchase  Price. In  consideration  of the transfer to Purchaser of the
     Assets and the  undertakings  of the Seller  Shareholders,  and  subject to
     adjustment  as  provided  below,  Purchaser  shall pay (and DPS shall cause
     Purchaser to pay) Forty-Six  Million Dollars  ($46,000,000)  (the "Purchase
     Price"), as follows:  (i) Thirty-Nine Million Eight Hundred Twenty Thousand
     Dollars  ($39,820,000)  shall  be paid  to the  individual  Sellers  in the
     amounts set forth on Schedule  1.3(a) by wire transfer at the Closing,  and
     (ii) Six Million One Hundred Eighty Thousand Dollars  ($6,180,000) shall be
     delivered  into escrow  (together,  the "Cash") to be held  pursuant to the
     escrow agreement in the form of Exhibit A (the "Escrow Agreement").

     The  foregoing  form of payment of the Purchase  Price is predicated on the
     presumption  that DPS  shall be  merged  with Key  Energy  Group,  Inc.,  a
     Maryland   corporation   ("Key"),  or  its  wholly  owned  subsidiary  (the
     "Merger").  If,  at the  time of the  Closing,  Key has not  completed  the
     Merger,  or, in the reasonable  judgment of Purchaser,  it is unlikely that
     the Merger will be completed,  then  Purchaser  shall have the right to pay
     Eleven Million Dollars  ($11,000,000)  of the Purchaser Price by delivering
     880,000 shares of unregistered  common stock, $0.01 par value per share, of
     DPS in the  names and in the  amounts  set forth on  Schedule  1.3(a)  (the
     "Shares").  The Shares shall be subject to a Registration  Rights Agreement
     in the form of Exhibit B (the "Registration Rights Agreement").

     Notwithstanding  the  foregoing,  the Purchase Price shall be reduced (by a
     reduction in the amount wire  transferred to the Sellers at the Closing) by
     the amount,  if any, (i) determined in accordance  with Section 1.5 of this
     Agreement  and (ii) by the amount of  accrued  vacation  shown on  Schedule
     3.1(u).  In  addition,  the  Purchaser  Price shall be  adjusted  after the
     Closing in accordance with Sections 1.3(b) and 1.3(c).

(a)  Seller Tax Basis and Fair Market Value of Assets. The fair market value and
     the tax basis for federal  income tax purposes of the Assets of the Sellers
     being  transferred to Purchaser shall be set forth on Schedule 1.3(b).  The
     Sellers and  Purchaser  each hereby  covenant  and agree that such  amounts
     reflect the fair market value of the Assets and that none of them, directly
     or indirectly,  through a subsidiary or affiliate or otherwise, will take a
     position on any income tax return,  before any governmental  agency charged
     with the collection of any income tax, or in any judicial  proceeding  that
     is in any way inconsistent  with the tax basis and fair market value of the
     Assets set forth on Schedule 1.3(b).  Such allocations will be reflected in
     Forms  8594 to be signed and filed by Seller and  Purchaser  in  accordance
     with  Section 1060 of the  Internal  Revenue Code of 1986,  as amended (the
     "Code"). In addition, the Purchase Price payable under Section 1.2 shall be
     allocated in the manner set forth on Schedule 1.3(b).

                         A. Assumption of Liabilities.

(a)  At the  Closing  and  except as  otherwise  specifically  provided  in this
     Section 1.4, Purchaser shall assume and agree to pay, discharge or perform,
     as appropriate, the liabilities and obligations of the Sellers set forth on
     Schedule 1.4(a) (the "Assumed  Liabilities");  provided,  however, that the
     aggregate amount of any debt and leases included in the Assumed Liabilities
     shall not exceed $150,000.

(b)  Notwithstanding Section 1.4(a), it is expressly understood that, other than
     obligations and liabilities expressly assumed in Section 1.4(a),  Purchaser
     shall not be liable for,  and shall not assume,  any of the Sellers' or the
     Seller Shareholders' obligations or liabilities,  whether known or unknown,
     matured or unmatured, or fixed or contingent,  including but not limited to
     liabilities  relating to events  occurring prior to the Closing,  any Taxes
     (as  hereinafter  defined,  other  than  those pro rated as of the  Closing
     Date), or any liabilities  under any Employee Benefit Plans of the Sellers.
     The Sellers shall remain obligated to pay and discharge any liabilities and
     obligations not expressly assumed by Purchaser hereby.  The Sellers and the
     Seller Shareholders hereby agree that they will indemnify Purchaser for any
     liabilities of the Sellers not expressly assumed pursuant to Section 1.4(a)
     by  Purchaser  and  Purchaser  and DPS agree that they will  indemnify  the
     Sellers  and  the  Seller   Shareholders   with   respect  to  the  Assumed
     Liabilities.

A.   Prorations.  All annual or periodic ad valorem fees, taxes and assessments,
     licensing fees and vehicle use fees, and similar  charges imposed by taxing
     authorities on the Assets  (collectively,  "Property Taxes") shall be borne
     and paid (a) by Seller for all full tax years or periods  ending before the
     date of the Closing and for that  portion of any tax year or period  ending
     on or after the effective date of Closing from the date of  commencement of
     such year or period to the date immediately preceding the effective date of
     the  Closing  and (b) by  Purchaser  for all  full  tax  years  or  periods
     beginning on or after the effective date of Closing and for that portion of
     any tax year or period ending on or after the effective date of the Closing
     from and including the effective  date of Closing to the final date of such
     year or period,  regardless of when or by which party such  Property  Taxes
     are actually paid to the  applicable  taxing  authority.  In addition,  all
     rents and other lease charges, power and utility charges,  license or other
     fees,  Assigned  Contracts,  and similar  items shall be allocated  between
     Purchaser and the Sellers  effective as of 12:01 a.m. on the effective date
     of  the  Closing.   Such  allocations   shall  be  determined  and  payment
     accordingly  made from one party to the  other,  as the case may be, on the
     date of the Closing to the extent they are known and agreed to by Purchaser
     and Seller; otherwise such allocations shall be determined and payment made
     (effective as of 12:01 a.m. on the  effective  date of the Closing) as soon
     as practicable but not later than the date 30 days thereafter.

     (and DPS shall cause Purchaser to deliver) that portion of the Cash subject
     to the Escrow Agreement to the escrow agent.

A.   Release of Liens. The Sellers shall cause all liens and other  encumbrances
     other  than  Permitted  Liens  affecting  the  Assets  to be  released  and
     discharged prior to Closing and shall provide  Purchaser with proof thereof
     including but not limited to copies of UCC-3 filings.

A.   Third Party  Consents.  To the extent that any of the Sellers' rights under
     any Contracts,  Authorizations  (as defined in Section 3.1(j)),  Permits or
     Equipment  Leases  assumed by Purchaser,  or other Assets to be assigned to
     Purchaser may not be assigned without the consent of another person,  which
     consent has not been obtained prior to the Closing,  this  Agreement  shall
     not  constitute an agreement to assign the same if an attempted  assignment
     would  constitute  a breach  thereof  or be  unlawful,  and the  applicable
     Seller, at such Seller's expense,  shall use reasonable  commercial efforts
     to obtain any such  required  consent(s)  as  promptly  as  possible  after
     Closing.  If any  consent is not  obtained or if any  attempted  assignment
     would be  ineffective  or would impair  Purchaser's  rights under or to the
     Asset in  question so that  Purchaser  would not acquire the benefit of all
     such rights,  the applicable Seller, to the maximum extent permitted by law
     and by the terms of any  documents  affecting  the Asset,  at such Seller's
     expense,  shall act for one year after the Closing as Purchaser's  agent in
     order to obtain for Purchaser the benefits  thereunder and shall cooperate,
     to the maximum  extent  permitted  by law and by the terms of any  document
     affecting the Asset,  with  Purchaser in any other  reasonable  arrangement
     designed to provide such benefits to Purchaser.

A.   Further  Assurances.  Each Seller from time to time after the  Closing,  at
     Purchaser's  request,  will execute,  acknowledge  and deliver to Purchaser
     such other  instruments of conveyance and transfer and will take such other
     actions and execute and deliver such other  documents,  certifications  and
     further  assurances  as Purchaser may  reasonably  request in order to vest
     more effectively in Purchaser, or to put Purchaser more fully in possession
     of, any of the Assets,  or to better enable Purchaser to complete,  perform
     or discharge any of the liabilities or obligations  assumed by Purchaser at
     the Closing  pursuant to Section 1.4.  Each of the parties  will  cooperate
     with the other and  execute  and  deliver to the other  parties  such other
     instruments  and documents and take such other actions as may be reasonably
     requested  from time to time by any other party as  necessary to carry out,
     evidence and confirm the intended purposes of this Agreement. If any of the
     Sellers dissolves within one year following the Closing Date,  effective as
     of the dissolution of such Seller, such Seller hereby irrevocably  appoints
     Purchaser or Purchaser's substitute as its attorney-in-fact coupled with an
     interest and with full power of substitution to carry out the provisions of
     this Section 2.5.

A.   No Equitable  Conversion.  Prior to the Closing,  neither the  execution of
     this Agreement nor the performance of any provision  contained herein shall
     cause  Purchaser to become  liable for any aspect or obligation of relating
     to the Assets or the Business.


                  I. ARTICLE - REPRESENTATIONS AND WARRANTIES

A.   Representations and Warranties of the Sellers and the Seller  Shareholders.
     Each of the Sellers  and the Seller  Shareholders,  jointly and  severally,
     hereby  represent  and warrant to Purchaser  and to DPS that the  following
     statements are true and correct, except as set forth on the Schedules, each
     of which  scheduled  exceptions  shall  specifically  identify the relevant
     section of this  Agreement  to which it  relates  and shall be deemed to be
     representations  and warranties as if made  hereunder;  provided,  however,
     that  the   representations   and  warranties  made  regarding  the  Seller

     validly existing and in good standing under the laws of the State of Texas.
     Each  of the  Sellers  is  duly  qualified  to do  business  and is in good
     standing as a foreign corporation in each jurisdiction where the conduct of
     the Business requires it to be so qualified, all of which jurisdictions are
     listed on  Schedule  3.1(a).  None of the  Sellers  is nor has ever been an
     investment  company  within the  meaning of the  Investment  Company Act of
     1940.

(a)  Corporate  Power;  Authorization;  Enforceable  Obligations.  Each  of  the
     Sellers  has the  corporate  power,  authority  and legal right to execute,
     deliver and perform this Agreement. The execution, delivery and performance
     of this  Agreement by each of the Sellers has been duly  authorized  by all
     necessary corporate action as of the Closing Date. This Agreement has been,
     and  the  other  agreements,  documents  and  instruments  required  to  be
     delivered  by  the  Sellers  in  accordance  with  the  provisions   hereof
     (collectively,  the "Seller Documents") will be duly executed and delivered
     on behalf of each Seller by duly  authorized  officers or directors of each
     Seller  and this  Agreement  constitutes,  and the  Seller  Documents  when
     executed  and  delivered  will  constitute,  the legal,  valid and  binding
     obligation of each of the Sellers  enforceable  against each of the Sellers
     in accordance with their respective terms except as the same may be limited
     by  applicable  bankruptcy,  insolvency,   reorganization,  or  other  laws
     affecting  the   enforcement  of  creditors'   rights   generally  and  the
     application of general principles of equity. The Board of Directors of each
     of  the  Sellers  has  approved  this   Agreement   and  the   transactions
     contemplated hereby.

(a)  Validity  of  Contemplated  Transactions,  Etc.  Except  as  identified  on
     Schedule 3.1(c), the execution,  delivery and performance of this Agreement
     by each of the  Sellers and the Seller  Shareholders  does not and will not
     violate,  conflict  with or result  in the  breach  of any  material  term,
     condition or provision  of,  require  notice to or the consent of any other
     person,  result  in the  acceleration  of or give  any  party  a  right  to

     Assigned  Contract  (including but not limited to Vehicle  Operating Leases
     and Equipment Leases) or other instrument, or understanding, whether or not
     assigned  hereby  (collectively,  the  "Contracts"),  by  which  any of the
     Sellers  may have  rights  or by which  any of the  Assets  may be bound or
     affected.

     As of the  Effective  Date and as of the Closing Date, no fact or condition
     exists or will exist which would result in the  termination  of or give any
     party to a Contract the right to terminate, modify, accelerate or otherwise
     change  the  existing  rights or  obligations  of the  Sellers in or to the
     Assets or the Business.  Except as otherwise identified on Schedule 3.1(c),
     no  Authorization,  approval or consent of, and no  registration  or filing
     with, any Governmental Entity is required in connection with the execution,
     delivery or  performance  of this Agreement by any of the Sellers or by any
     Seller Shareholder.

(a)  No Third Party  Options.  No person has any existing  agreements,  options,
     commitments or rights to acquire any of the Assets or any interest therein.

(a)  Financial Statements.  Attached hereto as Schedule 3.1(e) are the following
     financial  statements  (collectively,  the "Financial  Statements") for the
     Sellers:  (i) unaudited  consolidated and  consolidating  balance sheet and
     statement of income,  changes in  shareholders'  equity and cash flows, and
     unaudited  earnings before interest,  taxes,  depreciation and amortization
     ("Adjusted EBITDA") as of and for the fiscal years ended December 31, 1995,
     and December 31,  1996, and December 31, 1997 (the "Most Recent Fiscal Year
     End") and as of and for the 12 month period  ended June 30, 1998;  and (ii)
     the unaudited  consolidated balance sheet and statement of income,  changes
     in shareholders' equity and cash flow and Adjusted EBITDA (the "Most Recent
     Financial  Statements")  as of and for the six month  period ended June 30,
     1998 (the "Most Recent  Fiscal Month End") for the Sellers.  The  Financial
     Statements  (including  the notes thereto) have been prepared in accordance
     with generally accepted accounting principles applied on a consistent basis
     throughout  the  periods  covered  thereby,  present  fairly the  financial
     condition of the Sellers as of such dates and the results of  operations of
     the Sellers for such periods, are correct and complete,  and are consistent
     with the books and  records of the  Sellers  (which  books and  records are
     correct and complete);  provided,  however,  that the Most Recent Financial
     Statements are subject to normal  year-end  adjustments  (which will not be
     material,  individually  or in  the  aggregate)  and  lack  footnotes.  The
     Financial  Statements  fairly  present all of the activities of the Sellers
     that will be part of the operations and Business of the Sellers at Closing,
     and all  assets,  tangible  or  intangible,  and all  Contracts,  formal or
     informal whether or not in writing,  necessary to conduct the Business,  as
     actually  operating  as of the  Effective  Date  and as  set  forth  in the
     Financial  Statements,  will be owned by the  Sellers  (in the case of such
     assets)  and  will  be in  full  force  and  effect  (in  the  case of such
     Contracts) immediately prior to the Closing.

(a)  Taxes;  Tax and Other Returns and Reports.  All federal,  state,  local and
     foreign tax returns, reports, statements and other similar filings required
     to be filed by the Sellers and  affecting  the Assets or the Business  (the
     "Tax Returns") with respect to any federal,  state, local or foreign taxes,
     assessments,  interest,  penalties,  deficiencies,  fees,  duties and other
     governmental  charges or  impositions  (including  without  limitation  all
     income tax, unemployment compensation,  social security, payroll, sales and
     use, excise, gross receipts, value-added,  privilege, property, ad valorem,
     franchise,   license,   school  transfer,   mortgage  recording,   customs,
     withholding,  estimated  and other tax or  similar  governmental  charge or
     imposition  under  laws of the  United  States  or any  state,  county,  or
     municipal  entity,  agency  or  instrumentality  or  political  subdivision
     thereof or any foreign country or political subdivision thereof) insofar as
     same may affect the Assets or the Business  (the  "Taxes") have been timely
     filed with the appropriate  governmental  agencies in all  jurisdictions in
     which such Tax Returns are  required to be filed,  and all such Tax Returns
     properly  reflect the  liabilities  of Sellers  for Taxes for the  periods,
     property  and  events  covered  thereby.   All  Taxes,   including  without
     limitation,  those  which  are  called  for by the Tax  Returns,  have been
     properly  accrued or timely paid.  Purchaser  will have no liability to any
     person  or  taxing  authority  for  Taxes  relating  to  actions  or events
     occurring  prior to 12:01 a.m. on the  Closing  Date,  except as  otherwise
     provided by Section 1.5. The Sellers' warranties and representations  under
     this Section 3.1(f) shall be construed consistently with Section 1.5.

(a)  Books of Account. The books, records and accounts of the Sellers maintained
     with respect to the Business and the Assets fairly reflect, in all material
     respects and in  reasonable  detail,  the  transactions  and the assets and
     liabilities of each of the Sellers with respect to the Business.

(a)  Existing Condition.  Except as set forth on Schedule 3.1(h), and except for
     such changes as have affected the oil field  services  business  generally,
     since  December 31, 1997,  there has not been,  and through the date of the
     Closing there will not have been, any material adverse change in the Assets
     or  the  Business  or  the  financial  condition,  operations,  results  of
     operations,  or future  prospects  of the  Business.  Without  limiting the
     generality of the foregoing, since that date, except as otherwise stated on
     Schedule  3.1(h),  none of the Sellers has (i) entered into any transaction
     or agreement  affecting  the Business or the Assets  except in the ordinary
     course of business, consistent with past practice; (ii) encumbered, leased,
     licensed or transferred any tangible or intangible  assets which would have
     been  included in the Assets if the  Closing had been held on December  31,
     1997 or on any date since then;  (iii)  subjected  any of the Assets to any
     lien or other encumbrance of any nature whatsoever,  except in the ordinary
     course  of  business,  consistent  with  past  practices,  and  except  for
     Permitted  Liens  (defined  in  Section  3.1(i));  (iv)  entered  into  any
     agreement,  Contract,  lease, or license (or series of related  agreements,
     Contracts,  leases,  and licenses) outside the ordinary course of business,
     made any amendment to or terminated  any material  agreement  affecting the
     Business  or the  Assets,  or  canceled,  modified  or  waived  any  rights
     affecting the Business or the Assets, whether or not in the ordinary course
     of business; (v) changed any of the accounting principles followed by it or
     the methods of applying such principles; (vi) increased the compensation of
     any employee  other than in the ordinary  course of business,  entered into
     any  employment  Contract or collective  bargaining  agreement,  written or
     oral, or modified the terms of any existing Contract or agreement, made any
     other change in employment  terms for any of its  directors,  officers,  or
     employees  outside the ordinary  course of business,  or adopted,  amended,
     modified, or terminated any bonus,  profit-sharing,  incentive,  severance,
     retirement,  employee benefit plan, employee pension benefit plan, or other
     plan,  Contract,  or commitment  relating to its directors,  officers,  and
     employees;  (vii) suffered any damage,  destruction or loss to its property
     or other loss,  whether or not covered by  insurance,  (a)  materially  and
     adversely affecting the Business or Assets or (b) of any items which amount
     to  $20,000  or  more  in the  aggregate;  (vii)  granted  any  license  or
     sublicense  of any  rights  under  or  with  respect  to  any  of  Seller's
     intellectual   property  or  other  proprietary  rights;  (viii)  canceled,
     compromised,  waived,  or released any right or claim (or series of related
     rights and claims) outside of the ordinary course of business; (ix) delayed
     or  postponed  the  payment of  accounts  payable or any other  liabilities
     outside the  ordinary  course of business;  or (x)  committed to any of the
     foregoing.  In addition,  no party (including the Sellers) has accelerated,
     terminated,  modified,  or canceled  any  agreement,  Contract,  lease,  or
     license (or series of related agreements,  Contracts, leases, and licenses)
     to which any of the Sellers is or was a party or by which any of them is or
     was bound.
 
(a)  Title to Properties.  Notwithstanding anything herein to the contrary, each
     of the Sellers has good, valid and marketable title (or in the case of real
     property,  indefeasible  title) to all of its assets,  real,  personal  and
     mixed,  which would be included in the Assets if the Closing  took place on
     the Effective Date, which it purports to own,  including without limitation
     all assets reflected on the Schedules  hereto,  free and clear of all liens
     (including but not limited to tax liens),  claims,  restrictions  and other
     encumbrances  and  defects  of title of any nature  whatsoever,  except for
     (i) liens  for  current  real or  personal  property  taxes not yet due and
     payable;  (ii) Personal Properties as to which the applicable Seller is the
     lessee;  and (iii)  liens and other  exceptions  to title as  disclosed  in
     Schedules 3.1(i) (collectively, "Permitted Liens").

(a)  Compliance with Laws;  Authorizations.  Each of the Sellers has complied in
     all material  respects with each, and is not in material  violation of any,
     law,  ordinance or governmental  or regulatory rule or regulation,  whether
     federal,  state,  local or  foreign,  to which  the  Business  or Assets is
     subject  ("Regulations").  Each of the Sellers  owns,  holds,  possesses or
     lawfully  uses in the  operation of the  Business all permits,  franchises,
     licenses, easements, rights, applications, filings, registrations and other
     authorizations   ("Authorizations")  which  are  in  any  material  respect
     necessary  for it to  conduct  the  Business  as now  conducted  or for the
     ownership and use of the Assets in the conduct of the Business. Each of the
     Sellers   is  in   compliance   with  all   Regulations   related   to  the
     Authorizations.  All  such  Authorizations  are  listed  and  described  in
     Schedule 3.1(j). None of the Sellers is not in default,  nor has any of the
     Sellers  received  any notice of any claim of default,  with respect to any
     such Authorization. None of the Sellers has received any notice that any of
     the Authorizations  used by a Seller in the operation of the Business would
     not or cannot be renewed or continued  in the ordinary  course of business,
     and all such  Authorizations are renewable by the Sellers by their terms or
     in the ordinary  course of business.  No person other than the Sellers owns
     or has any proprietary, financial or other interest (direct or indirect) in
     any Authorization.

(a)  Transactions  With Affiliates.  Any and all material  transactions  between
     each of the Sellers and its  Affiliates (as defined  herein)  affecting the
     Business or the Assets  have been upon terms  substantially  comparable  to
     those that would have been  available to such Seller from third  parties in
     arms length transactions.

(a)  Litigation.  Except as set  forth on  Schedule  3.1(l),  no  litigation  or
     administrative  proceeding,  including any  arbitration,  investigation  or
     other proceeding of or before any court,  arbitrator or Governmental Entity
     is pending or, to the best knowledge of the Sellers, threatened against any
     Seller,  which  relates  to the  Business  or  Assets  or the  transactions
     contemplated by this  Agreement,  nor do the Sellers know of any reasonably
     likely  basis  for  any  such  litigation,  arbitration,  investigation  or
     proceeding,  the result of which could  reasonably be expected to adversely
     affect the Assets or Business,  or the  transactions  contemplated  hereby.
     None of the  Sellers  is a party to or  subject  to the  provisions  of any
     judgment, order, writ, injunction, decree or award of any court, arbitrator
     or Governmental Entity which may materially  adversely affect the Assets or
     Business,  or the  transactions  contemplated  hereby.  The  Sellers  shall
     reimburse and indemnify  Purchaser  for any damages,  liabilities  or other
     losses  incurred  by  Purchaser  in  connection  with  any and all  matters
     identified on Schedule 3.1(l).

(a)  Equipment. The Operating Assets are at the execution of this Agreement, and
     will be at Closing,  in good working  condition and  sufficient to maintain
     the operation of the Business.

(a)  Contracts and Commitments.  Except as set forth on Schedule 3.1(n), none of
     the Sellers is a party to any written or oral:

(i)  lease under which it is either  lessor or lessee  relating to the Assets or
     any property at which the Assets are located  other than those set forth on
     the Schedules to this Agreement;

(i)  Contract or agreement for any capital expenditure or leasehold  improvement
     relating to the Assets or Business;

(i)  Contract or agreement limiting or restraining such Seller, its successor or
     assigns,  from engaging or competing in any manner in the Business,  or any
     agreement  concerning  confidentiality,  nor is any  employee of any Seller
     subject to any such Contract;

(i)  agreement (or group of related  agreements) for the purchase or sale of raw
     materials,  supplies,  products,  or  other  personal  property  or for the
     furnishing  or receipt of services,  the  performance  of which will extend
     over a period of one year or result in a material loss to such Seller;

(i)  collective bargaining agreement;

(i)  agreement for the employment of any  individual on a full-time,  part-time,
     consulting or other basis,  other than an oral  Contract for  employment at
     will; or

(i)  agreement under which the  consequences  of a default or termination  could
     have a material adverse effect on the Business or the financial  condition,
     operations, results of operations, or future prospects of any Seller.

     Each of the Contracts and agreements  listed in Schedule  3.1(n),  and each
     other  Assigned  Contract,  including  but not limited to Equipment  Leases
     under which  Purchaser is to acquire  rights or  obligations,  is valid and
     enforceable  in accordance  with its terms;  each of the Sellers is, and to
     each Seller's  knowledge all other parties  thereto are, in compliance with
     the provisions thereof; none of the Sellers is, and to each of the Seller's
     knowledge, no other party is, in default in the performance,  observance or
     fulfillment  of any material  obligation,  covenant or condition  contained
     therein; and to each of the Seller's knowledge, no event has occurred which
     with or  without  the  giving of notice  or lapse of time,  or both,  would
     constitute  a  default  thereunder.   Furthermore,   no  such  Contract  or
     agreement,   in  the  reasonable   opinion  of  the  Sellers  contains  any
     requirement with which there is a reasonable likelihood a Seller or, to the
     Sellers' knowledge, any other party thereto will be unable to comply.

     or groundwater of any real properties or adjoining properties.

F.   "Remediation"  shall  mean all  actions,  whether  undertaken  pursuant  to

     or (b) to prevent or control the Release of  Hazardous  Substances  so that
     they do not migrate or endanger  or threaten to endanger  public  health or
     welfare or the indoor or outdoor environment.

(i)  Representations  and  Warranties.  The  parties  agree  that the  following
     representations  and  warranties  shall govern in the event of any conflict
     between the  provisions of this Section  3.1(o) and any other  provision of
     this  Agreement  or of  the  other  agreements  or  conveyance  instruments
     contemplated hereby. The Sellers and the Seller  Shareholders,  jointly and

     which are required in  connection  with the conduct of the  Business  under
     Environmental, Health and Safety Laws;

B.   Each of the  Sellers  is in  compliance  in all  material  respects  in the
     conduct  of the  Business  with all terms and  conditions  of the  required
     Authorizations, and is also in compliance in all material respects with all
     Environmental,  Health and Safety  Laws and with any plan  required by law,
     order,  decree,  judgment,  or injunction entered,  promulgated or approved
     thereunder, and, with any notice or demand letter issued thereunder;

C.   None of the Sellers is aware of, nor has any Seller received notice of, any

     of the Business with any Environmental,  Health and Safety Laws or with any
     plan  required  by law,  order,  decree,  judgment or  injunction  entered,
     promulgated or approved  thereunder,  or, with any notice or demand letter,
     or which may otherwise form the basis of any claim,  action,  demand, suit,
     proceeding,  hearing,  study or  investigation,  based on or related to the
     manufacture,  processing,  distribution, use, treatment, storage, disposal,
     transport, or handling, or the emission,  discharge,  release or threatened
     release into the environment, of any Hazardous Substance;

D.   There is no civil, criminal or administrative  action, suit, order, demand,
     claim,   hearing,   notice  or   demand   letter,   notice  of   violation,
     investigation,  or  proceeding  pending  or,  to  the  Sellers'  knowledge,
     threatened  against  any  Seller  in  connection  with the  conduct  of the
     Business relating in any way to any Environmental, Health and Safety Laws;

E.   Each of the Sellers agrees to cooperate with  Purchaser,  both prior to and
     following the Closing,  in connection with Purchaser's  application for the
     transfer,  renewal or issuance of any Authorizations or Purchaser's efforts
     to  satisfy  any  Environmental,  Health  and  Safety  Laws  involving  the
     Business,  (provided,  however,  that the Sellers  shall not be required to
     incur any material expense in connection therewith);

F.   None of the Sellers, in connection with the operation of the Business,  has
     handled  or  disposed  of  any   Hazardous   Substance   in   violation  of
     Environmental,  Health and Safety  Laws,  arranged  for the disposal of any
     Hazardous Substance in violation of Environmental,  Health and Safety Laws,
     exposed any  employee or other  individual  to any  Hazardous  Substance or
     condition  in  violation  of  Environmental,  Health  and Safety  Laws,  or
     operated any Assets in any manner that could form the basis for any present
     or  future  action,  suit,  proceeding,  hearing,  investigation,   charge,
     complaint,  claim,  or  demand  for  damage  to, or for  investigation  and
     Remediation  of,  any  site,  location,   or  body  of  water  (surface  or
     subsurface), for any illness of or personal injury to any employee or other
     individual,  or for any reason under any  Environmental,  Health and Safety
     Laws or Authorizations;
 
G.   Each of the Sellers has provided Purchaser all material information in such
     Seller's   control  or  possession   relating  to:  (1)  the  existence  of
     Contamination  on  or  affecting  all  Assets;   (2)  compliance  with  all
     Environmental,  Health  and  Safety  Laws;  and (3) any  alleged  or actual
     Environmental Losses; and

H.   No oral or written  agreements,  including  but not limited to indemnity or
     cleanup  agreements,  exist between the Sellers or the Seller  Shareholders
     and any third parties, relating to or concerning the environmental,  safety
     or health conditions of the Assets.

(a)  Availability of Documents.  Each of the Sellers has provided Purchaser with
     copies of all material  documents,  including without limitation all of the
     Contracts,   permits,  licenses,   patents,   trademarks,   copyrights  and
     applications therefor listed in the Schedules. Each of the Sellers will use
     its best efforts to obtain any such  documents  not in its  possession  and
     promptly  deliver same to Purchaser.  Such copies are true and complete and
     include all amendments,  supplements and  modifications  thereto or waivers
     currently in effect thereunder.

(a)  Assets.  Except as set forth in  Schedule  3.1(q),  the Assets  include all
     rights and property, other than real property, reasonably necessary for the
     conduct of the  Business  by  Purchaser  in the manner in which it has been
     conducted by the Sellers for the period of time  reflected in the Financial
     Statements  and for the conduct of the Business as  presently  conducted by
     each of the Sellers, and no property excluded from the Assets under Section
     1.1(b),  other than real property,  constitutes property or rights material
     to the Business.  Each such tangible Asset is structurally  sound, has been
     maintained  in  accordance  with  normal  industry  practice,  is  in  good
     operating  condition  and  repair,  subject  to normal  wear and  tear,  is
     suitable for the purposes for which it presently is used and for use in the
     continued  conduct of the  Business  in  substantially  the same  manner as
     conducted  prior to the Closing.  None of the tangible Assets is in need of
     maintenance or repairs except for ordinary routine  maintenance and repairs
     that are not material in nature or cost. Any  modifications  that have been

     accordance with normal industry practice.

(a)  Restrictions.  None of the  Sellers is a party to any  material  agreement,
     license, Permit,  Authorization or other instrument or any understanding or
     oral agreement,  and none of the Sellers is subject to any charter or other
     corporate restriction or any judgment,  order, writ, injunction,  decree or
     award,  which  materially  adversely  affects or  materially  restricts the
     Business or Assets.

(a)  Conditions  Affecting the Sellers.  Except as provided in this Agreement or
     disclosed  in the  Schedules,  and except for  conditions  that affect as a
     whole the oil field servicing industry generally, there is no fact known to
     the Sellers which may reasonably be expected to materially adversely affect
     the Business  considered as a whole.  Notwithstanding  the  foregoing,  the
     Sellers  and the  Seller  Shareholders  shall not be deemed to have made to
     Purchaser  or DPS any  representation  or warranty  other than as expressly
     made in this Article II. Without  limiting the generality of the foregoing,
     the  Sellers  and  the  Seller  Shareholders  make  no  representations  or
     warranties  to  Purchaser  or DPS  with  respect  to (i)  any  projections,
     estimates or budgets heretofore delivered to or made available to Purchaser
     or DPS of future  revenues,  expenses or  expenditures or future results of
     operations;  or (ii) except as expressly  covered by a  representation  and
     warranty  contained in this Article II, any other  information or documents
     (financial or otherwise) made available to Purchaser or DPS or its counsel,
     accountants or other advisors with respect to the Sellers,  the Business or
     the Assets.

(a)  Employee Benefit Plans.  Schedule 3.1(t) lists all of the Sellers' Employee
     Benefit Plans.  None of the Sellers is now and for the preceding five years
     has not been, a party to any "employee  pension benefit plan" as defined in
     Section 3(2) of the Employee  Retirement  Income  Security Act of 1974,  as
     amended  ("ERISA").  None of the Sellers is under any legal  obligation  to
     create a new Employee  Benefit Plan, or amend an existing  Employee Benefit
     Plan,  that  would  affect  any of the  employees  of the  Sellers  who are
     employed or otherwise  compensated  for activities  involving the Assets or
     the Business ("Affected Employees").

(i)  Purchaser  shall  have no  responsibility  or  liability  with  respect  to
     benefits  which may have accrued or been promised to any Affected  Employee
     under  any  "Employee  Benefit  Plan" of the  Sellers  or any  member  of a
     Seller's  control group as determined  under Sections  414(b) or (c) of the
     Code, or which form an affiliated  service group with any of the Sellers or
     the Seller  Shareholders  within the meaning of Section 414(m) of the Code.
     The term "Employee Benefit Plan" includes, but is not limited to any profit
     sharing, stock, bonus, 401(k), nonqualified deferred compensation, medical,
     dental,  workers'  compensation,   life  insurance,   incentive,   vacation
     benefits,  and fringe  benefits plan or program and each "employee  benefit
     plan"  described  in Section  3(3) of ERISA.  The Sellers  shall  indemnify
     Purchaser  as  provided  in Section  VI of this  Agreement  against  and in
     respect of any Damages (as  hereinafter  defined)  which arise  directly or
     indirectly  with respect to an Employee  Benefit Plan.  None of the Sellers
     contributes  to any  "multiemployer  plan" as defined  in Section  3(37) or
     4001(o)(3) of ERISA.

(i)  The  Sellers  shall  pay and be liable to  Purchaser,  and shall  indemnify
     Purchaser as provided in Section VI of this Agreement, from and against and
     in respect of any and all  Damages  that arise under  section  4980B of the
     Code,  imposed upon,  incurred by, or assessed against  Purchaser or any of
     its employees arising by reason of or relating (x) to any failure to comply
     with the continuation health care coverage requirements of section 4980B of
     the Code,  which  failure  occurred  with  respect to any  current or prior
     employee of Seller or any  "qualified  beneficiary"  of such  employee  (as
     defined  in  section  4980B(g)(I)  of the Code) on or prior to the  Closing
     Date, and (y) to the extent, if any, of any amounts paid by Purchaser under
     its health plan to any current or prior employee of the Sellers as a result
     of a  "qualifying  event" (as defined in Section  4980B(f)(3)  of the Code)
     which  occurred  prior  to  the  Closing  Date,  over  the  amount  of  the
     "applicable  premium" (as defined in section  4980B(f)(4) of the Code) paid
     to Purchaser or Purchaser's health plan, by such current or prior employee.
     References to the Code include any amendments  that may be made to the Code
     from time to time.

(a)  Personnel.  Schedule  3.1(u) lists the names and monthly or, as applicable,
     hourly rates of compensation  (including base salary,  bonus,  commissions,
     and  incentive  pay) of the Affected  Employees and  summarizes  the bonus,
     profit sharing,  percentage compensation,  automobile,  club membership and
     other benefits,  if any, paid or payable to the Affected  Employees  during
     the  Sellers'  1997  fiscal  year  and from  the  beginning  of each of the
     Seller's  current  fiscal year to the  Effective  Date and  identifies  all
     accrued vacation relating to the Affected  Employees.  Schedule 3.1(u) also
     contains a brief  description  of all material terms of all written or oral
     employment agreements,  severance agreements,  confidentiality  agreements,
     noncompete  agreements or similar agreements to which any Affected Employee
     is or may be subject.  The Sellers have delivered to Purchaser accurate and
     complete copies of all such agreements, and all other agreements, plans and
     other  instruments  to which any of the  Sellers is a party and under which
     the Affected  Employees are entitled to receive benefits of any nature.  To
     the Sellers'  knowledge,  and except as set forth on Schedule  3.1(u),  the
     employee  relations of each of the Sellers are good and there is no pending
     or threatened  controversy,  labor dispute or union  organization  campaign
     between any Seller and any of its  employees or former  employees.  None of
     the Affected  Employees are  represented by any labor union or organization
     nor is any Seller a party to any collective bargaining agreement. Except as
     set forth on Schedule  3.1(u),  each of the Sellers is in compliance in all
     material respects with all federal and state laws respecting employment and
     employment  practices,  terms and  conditions of  employment  and wages and
     hours and is not engaged in any unfair labor practices.  There is no unfair
     labor practices complaint or charge of employment  discrimination  pending,
     or  threatened  with  respect to an Affected  Employee  before the National
     Labor Relations Board, the Equal Employment Opportunity Commission,  or any
     other state,  federal or local court or Governmental Entity, or any strike,
     labor dispute,  work slowdown or work stoppage  pending or, to the Sellers'
     knowledge,  threatened  against or  involving  any Seller,  and none of the
     Sellers has experienced any material labor difficulty during the last three
     years.  Except  as  otherwise  specifically  provided  in  this  Agreement,
     Purchaser shall have no liability for any severance or termination expenses
     of any Seller or Seller  Shareholder,  including  accrued vacation and sick
     leave time, in connection  with the  termination of employment by Seller of
     any Affected Employee, whether or not such person is employed by Purchaser.
     None  of the  Sellers  nor any  Seller  Shareholder  shall  have  any  such
     liability in connection  with the termination of employment by Purchaser of
     any Affected  Employee who has been employed by Purchaser and  subsequently
     terminated by Purchaser after the Closing.

(a)  Legal Compliance;  Undisclosed Liabilities. Each of the Sellers and each of
     their  predecessors and "Affiliates" (as defined in Rule 12b-2  promulgated
     under the Securities Exchange Act of 1934) has complied with all applicable
     laws (including rules, Regulations,  codes, plans, injunctions,  judgments,
     orders, decrees, rulings, and charges thereunder) of federal, state, local,
     and foreign  governments (and all agencies thereof),  and no action,  suit,
     proceeding,  hearing,  investigation,  charge, complaint, claim, demand, or
     notice has been filed or commenced against any of them alleging any failure
     so to comply.  None of the Sellers has any  liability and there is no basis
     for any present or future action, suit, proceeding, hearing, investigation,
     charge,   complaint,   claim,  or  demand  against   Seller),   except  for
     (i) liabilities  set forth on the face of the  Financial  Statements,  (ii)
     liabilities  which have arisen in the ordinary  course of business (none of
     which results from,  arises out of, relates to, is in the nature of, or was
     caused by any breach of Contract,  breach of warranty,  tort, infringement,
     or violation of law), and (iii) liabilities listed on Schedule 3.1(l).

(a)  Inventory.  All  inventory of the Sellers,  whether or not reflected in the
     balance  sheets,  consists  of a  quality  and  quantity  usable  and where
     applicable, salable in the ordinary course of business.

(a)  Warranty.  Schedule  3.1(x)  includes  copies  of the  standard  terms  and
     conditions  of sale or lease for each of the  products  and services of the
     Sellers   (containing   applicable   guaranty,   warranty,   and  indemnity
     provisions).  The products and services  provided by the Sellers  have,  in
     each case, been in conformity with all applicable  contractual  commitments
     and all  express and  implied  warranties,  and none of the Sellers has any
     liability  (and there is no basis for any present or future  action,  suit,
     proceeding,  hearing,  investigation,  charge, complaint,  claim, or demand
     against any of them giving rise to any liability) for replacement or repair
     or other damages in connection  therewith,  subject only to the reserve for
     warranty claims set forth on the face of the Financial  Statements  (rather
     than in any notes  thereto) as adjusted for the passage of time through the
     Closing  Date in  accordance  with  the past  custom  and  practice  of the
     Sellers.  No  service  provided  by any of the  Sellers  is  subject to any
     guaranty, warranty, or other indemnity beyond the applicable standard terms
     and conditions of sale or lease listed in Schedule 3.1(x).

(a)  Investment.  The Sellers and the Seller  Shareholders  understand  that the
     Shares have not been, nor will be,  registered  under the Securities Act of
     1933 or under any state  securities  laws and are being offered and sold in
     reliance upon federal and state  exemptions for  transactions not involving
     any public offering. Each of the Sellers is acquiring the Shares solely for
     its  own  account  for  investment  purposes,  and  not  with a view to the
     distribution thereof. The Sellers and Seller Shareholders are sophisticated
     investors, with knowledge and experience in business and financial matters,
     and are able to bear the economic  risk and lack of  liquidity  inherent in
     holding the Shares.  The Sellers and Seller  Shareholders  acknowledge  and
     agree that (i) they have fully reviewed all periodic reports filed with the
     Securities and Exchange  Commission by DPS within the past 12 months,  (ii)
     they have had the  opportunity to ask questions of and receive  information
     from representatives of DPS and have received all information necessary for
     each of them to  evaluate  the merits  and risks  inherent  in holding  the
     Shares,  (iii) the stock  certificates  issued to each Seller  shall bear a
     restrictive  legend  indicating  that the Shares  have not been  registered
     under the Securities Act or any other state securities laws.

A.   Representations and Warranties of Purchaser. Purchaser and DPS, jointly and
     severally, represent and warrant to the Sellers and the Seller Shareholders
     as follows:

(a)  Existence.  Purchaser is a limited partnership validly existing and in good
     standing under the laws of the State of Delaware. DPS is a corporation duly
     organized,  validly  existing  and in good  standing  under the laws of the
     State of Texas.

(a)  Power and  Authorization.  Purchaser and DPS each has the power,  authority
     and legal  right to  execute,  deliver  and  perform  this  Agreement.  The
     execution,  delivery and  performance of this Agreement by Purchaser and by
     DPS have been duly  authorized by all necessary  corporate and  partnership
     action.  This  Agreement  has been duly executed and delivered by Purchaser
     and  DPS and  constitutes  the  legal,  valid  and  binding  obligation  of
     Purchaser and DPS, enforceable against Purchaser and DPS in accordance with
     its  terms  except as the same may be  limited  by  applicable  bankruptcy,
     insolvency,  reorganization,  or other laws  affecting the  enforcement  of
     creditors'  rights  generally and the application of general  principles of
     equity.

(a)  Noncontravention. The execution, delivery and performance of this Agreement
     by Purchaser and DPS does not and will not violate, conflict with or result
     in the breach of any material  term,  condition or provision of, or require
     the consent of any other party which has not already been  obtained  under,
     (i) any existing  law,  ordinance,  or  governmental  rule or regulation to
     which  Purchaser  or  DPS is  subject,  (ii)  any  judgment,  order,  writ,
     injunction,  decree or award of any court,  arbitrator or  governmental  or
     regulatory official,  body or authority which is applicable to Purchaser or
     DPS, (iii) the Limited Partnership Agreement,  Articles of Incorporation or
     Bylaws or equivalent  organizational documents, or any securities issued by
     Purchaser,  its  general  partner,  or DPS as the case may be,  or (iv) any
     Contract to which  Purchaser or DPS is a party or by which Purchaser or DPS
     is otherwise bound. Except as otherwise contemplated by this Agreement,  no
     Authorization,  approval or consent of, and no registration or filing with,
     any  Governmental  Entity is required  in  connection  with the  execution,
     delivery and performance of this Agreement by Purchaser or DPS.

(a)  Shares. The Shares, if issued and delivered in accordance with the terms of
     this Agreement for the  consideration  expressed  herein,  will be duly and
     validly  issued,   fully  paid  and  nonassessable  and  will  be  free  of
     restrictions  on transfer other than  restrictions on transfer set forth in
     this Agreement and under applicable state and federal securities laws.

(a)  No  Material  Misstatements.  The  documents  filed by DPS  pursuant to the
     Securities  Exchange  Act of 1934 do not contain any untrue  statement of a
     material fact or omit to state a material  fact  necessary in order to make
     the  statements  made, in the light of the  circumstances  under which they
     were made, not misleading.

A.   Survival.  All  statements  of  fact  contained  in any  written  statement
     (including  financial  statements),  certificate,  instrument  or  document
     delivered  by or on behalf of any party hereto  pursuant to this  Agreement
     shall  be  deemed   representations  and  warranties  of  such  party.  All
     covenants,  agreements,  representations  and  warranties of the parties to
     this Agreement  shall survive and remain in full force and effect after the
     Closing Date and shall not be affected by any  investigation  heretofore or
     hereafter made by and on behalf of any of them or be deemed merged into any
     instruments  or agreements  delivered in connection  with this Agreement or
     otherwise in connection with the transactions  contemplated hereby. Subject
     to the limitations on indemnification  obligations set forth in Article VI,
     the representations and warranties set forth in this Article III and in any
     schedule,  certificate or instrument delivered by or on behalf of any party
     hereto in connection with this  Agreement,  shall terminate on the close of
     business on the fifth anniversary of the Closing Date,  following which all
     the  parties  shall  cease to have any right to bring any action or present
     any claim for a breach of such  representations  and  warranties;  provided
     that there shall be no termination of any such  representation and warranty
     as to which a bona fide  claim has been  asserted  and notice of such claim
     has been delivered prior to such termination date.  Nothing in this Section
     3.3 shall at any time relieve any party hereto from the performance of such
     party's  agreements,  covenants and undertakings set forth in the Agreement
     or in any other  agreement  executed  and  delivered by or on behalf of any
     party hereto at or prior to the Closing pursuant to this Agreement.


                    I. ARTICLE - AGREEMENTS PENDING CLOSING

A.   Agreements of the Sellers and the Seller Shareholders  Pending the Closing.
     The Sellers and the Seller  Shareholders  covenant and agree that,  pending
     the Closing and except as otherwise agreed to in writing by Purchaser, they
     shall take the following actions:

(a)  Business in the Ordinary Course.  The Business shall be conducted solely in
     the  ordinary  course  consistent  with past  practice.  The Sellers  shall
     continue to maintain and service the physical Assets used in the conduct of
     the Business in good working condition consistent with past practices.  The
     Sellers shall not cause or permit to occur any of the events or occurrences
     described in Section 3.1(h) (Existing Condition). Each of the Sellers shall
     use its reasonable  commercial efforts to maintain in full force and effect
     all  Authorizations  currently  in effect  and used in the  conduct  of the
     Business, and shall comply with all Regulations applicable to the Business,
     the  noncompliance  with which might  materially  and adversely  affect the
     Business or the Assets.  The Sellers  shall not (i) sell,  lease,  license,
     assign  or  otherwise  transfer  any of the  Assets,  (ii)  enter  into any
     Contract outside of the ordinary course of business,  (iii) amend,  modify,
     terminate,  waive  any  material  provision  of,  or  breach  any  material
     Contract,  or (iv)  cancel,  terminate  or cause  or  allow  to  lapse  any
     insurance coverage affecting the Business or the Assets.

(a)  Conduct of  Business.  Each of the  Sellers  shall use its best  efforts to
     conduct  the  Business  in such a  manner  that  on the  Closing  Date  the
     representations  and warranties  contained in this Agreement shall be true,
     except as  specifically  contemplated  by this  Article  IV, as though such
     representations   and  warranties  were  made  on  and  as  of  such  date.
     Furthermore, each of the Sellers shall cooperate with Purchaser and use its
     reasonable  commercial  efforts  to  cause  all  of the  conditions  to the
     obligations  of Purchaser  under this Agreement to be satisfied on or prior
     to the Closing Date.

(a)  Exclusive Dealing. Until such time, if any, as this Agreement is terminated
     pursuant to Article  VIII,  none of the Sellers shall (nor shall any Seller
     cause its  representatives  and agents directly or indirectly,  through any
     third party or otherwise  to), sell or encumber any part of the Assets,  or
     solicit,  initiate,  encourage or  entertain  any  inquiries,  proposals or
     offers from, discuss or negotiate with, provide any non-public  information
     to or consider the merits of any  inquiries  or  proposals  from any person

     this Agreement by Purchaser or DPS.

A.   Procedure.  All claims for  indemnification  pursuant to Article VI of this
     Agreement shall be asserted and resolved as follows:

(a)  An Indemnitee  promptly shall give the Indemnitor notice of any matter that
     an  Indemnitee  has  determined  has given or could give rise to a right of
     indemnification under this Agreement, stating the amount of the Damages, if
     known,   and   method  of   computation   thereof,   all  with   reasonable
     particularity,  and stating with  particularity  the nature of such matter.
     Failure to provide such notice shall not affect the right of an  Indemnitee
     to indemnification except to the extent such failure shall have resulted in
     liability to the Indemnitor  that actually could have been avoided had such
     notice been provided.

(a)  The  obligations  and  liabilities of an Indemnitor with respect to Damages
     arising   from   claims  of  any  third  party  that  are  subject  to  the
     indemnification  provided  for in this  Article VI ("Third  Party  Claims")
     shall be governed by and contingent upon the following additional terms and
     conditions.  If an Indemnitee receives notice of any Third Party Claim, the
     Indemnitee  shall give the  Indemnitor  written  notice of such Third Party
     Claim and the Indemnitor may, at its option, assume and control the defense
     of such Third Party Claim at the  Indemnitor's  expense and through counsel
     of the Indemnitor's choice reasonably acceptable to the Indemnitee.  If the
     Indemnitor  assumes  the  defense  against  any such Third  Party  Claim as
     provided above,  the Indemnitee  shall have the right to participate at its
     own expense in the defense of such asserted liability, shall cooperate with
     the  Indemnitor  in such  defense and will  attempt to make  available on a
     reasonable  basis  to the  Indemnitor  all  witnesses,  pertinent  records,
     materials and  information in its possession or under its control  relating
     thereto as reasonably  required by the  Indemnitor.  If the Indemnitor does
     not elect to conduct the defense  against any such Third Party  Claim,  the
     Indemnitor  shall pay all reasonable  costs and expenses of such defense as
     incurred  and shall  cooperate  with the  Indemnitee  (and be  entitled  to
     participate)  in such  defense  and  attempt to make  available  to it on a
     reasonable basis all such witnesses,  records, materials and information in
     its possession or under its control relating thereto as reasonably required
     by the  Indemnitee.  Except for the  settlement of a Third Party Claim that
     involves the payment of money only and for which the  Indemnitee is totally
     indemnified by the Indemnitor,  no Third Party Claim may be settled without
     the written consent of the Indemnitee.

A.   Survival;  Limitations on Amount. All of the representations and warranties
     of the parties  contained in this  Agreement  shall survive until the fifth
     anniversary of the Closing (even if the damaged party knew or had reason to
     know of any  misrepresentation or breach of warranty at the time of Closing
     except  as  disclosed  on the  Schedules).  No  party  who  is a  Purchaser
     Indemnified Party shall make a claim for indemnification  with respect to a
     claim  based  upon a breach  of a  representation  or  warranty  until  the
     aggregate amount of the Purchaser Losses  attributable to claims for breach
     of  representations  or warranties is at least $50,000,  at which time, all
     such amounts may be claimed. No party who is Seller Indemnified Party shall
     make a claim for  indemnification  with  respect  to a claim  based  upon a
     breach of a  representation  or warranty until the aggregate  amount of the
     Seller  Losses  attributable  to claims  for breach of  representations  or
     warranties  is at least  $50,000 at which  time,  all such  amounts  may be
     claimed.  However,  neither the Sellers and the Seller  Shareholders on the
     one hand, nor Purchaser or DPS on the other hand,  shall be required to pay
     in the aggregate  more than  $25,000,000 to satisfy claims made pursuant to
     this Article 6 for claims based upon  breaches of the  representations  and
     warranties.

A.   Payment; Failure to Pay Indemnification. Payment of any amount due pursuant
     to this Article VI shall be made by the Indemnitor  within 30 business days
     after notice is sent by the Indemnitee.  If and to the extent an Indemnitee
     makes written  demand upon an Indemnitor  for  indemnification  pursuant to
     this Article VI and the  Indemnitor  refuses or fails to pay in full within
     30  business  days  of such  written  demand,  then  the  Indemnitee  after
     arbitration of the matter may use any legal or equitable  remedy to collect
     from the Indemnitor the amount of its Damages.  Nothing contained herein is
     intended to limit or constrain an Indemnitee's rights against an Indemnitor
     for indemnity,  the remedies herein being cumulative and in addition to all
     other rights and remedies of the Indemnitee.

A.   Express   Negligence.   THE  FOREGOING   INDEMNITIES  ARE  INTENDED  TO  BE
     ENFORCEABLE  AGAINST THE PARTIES IN  ACCORDANCE  WITH THE EXPRESS TERMS AND
     SCOPE THEREOF NOTWITHSTANDING TEXAS' EXPRESS NEGLIGENCE RULE OR ANY SIMILAR
     DIRECTIVE THAT WOULD PROHIBIT OR OTHERWISE LIMIT INDEMNITIES BECAUSE OF THE
     NEGLIGENCE (WHETHER SOLE, CONCURRENT,  ACTIVE OR PASSIVE) OR OTHER FAULT OR
     STRICT LIABILITY OF ANY OF THE INDEMNIFIED PARTIES.

A.   Other Rights and Remedies Not Affected.  The indemnification  rights of the
     parties  under this  Agreement are  independent  of and in addition to such
     rights  and  remedies  as the  parties  may  have  at law or in  equity  or
     otherwise  for any  misrepresentation,  breach of  warranty  or  failure to
     fulfill  any  agreement  or  covenant  hereunder  on the part of any  party
     hereto,   including   without   limitation   the  right  to  seek  specific
     performance,  rescission or  restitution,  none of which rights or remedies
     shall be affected or diminished hereby.

     to one or more other parties  pursuant to this Section 7.1, the arbitrators
     selected with respect to each such Dispute Notice may elect,  in their sole
     discretion,  to  combine  the  matters  set  forth in one or more,  but not
     necessarily all, of the Dispute Notices into one or more hearings, in which
     case, the  arbitrators  shall adjust the time deadlines set forth herein as
     they  determine  appropriate,  and shall decide which one of them will hear
     the evidence and render a final determination with respect to each hearing.

(a)  Conclusion of Arbitration.  The arbitrator shall make the final decision as
     to the parties'  respective  rights and  obligations.  The  arbitrator  may
     determine  that a party is entitled to damages  hereunder  from one or more
     other  parties,  and the manner in which  such  damages  shall be  assessed
     against the other parties.  However, the arbitrator may not award emotional
     distress or punitive damages.

(a)  Expenses of Arbitrators.  The expenses of the arbitrator(s) shall be shared
     equally by the parties to the arbitration.

     incurred  prior to the Closing Date relating to the Business and the Assets
     (except for those  expressly  assumed by Purchaser  hereunder and except to
     the extent prorated pursuant to Section 1.5),  including without limitation
     any liabilities or obligations to employees, trade creditors and clients of
     the Business.  The Sellers,  Seller  Shareholders,  Purchaser and DPS shall
     each use commercially  reasonable efforts following the Closing to ensure a
     smooth transition of the Business to Purchaser.

A.   Maintenance  of Books and  Records.  The Sellers and  Purchaser  shall each
     preserve all records  possessed  by such party  relating to the Business or
     Assets  prior  to the  Closing  Date for a period  of at  least  six  years
     following  the fiscal year to which the records  relate.  After the Closing
     Date,  where there is a legitimate  purpose,  such party shall  provide the
     other parties and their  representatives with access, upon prior reasonable
     written  request  specifying  the need therefor,  during  regular  business
     hours,   to  (a)  the  officers,   employees   and  other  duly   appointed
     representatives  of such party and (b) the books of account  and records of
     such party, but, in each case, only to the extent relating to the Assets or
     Business  prior to the  Closing  Date,  and the  other  parties  and  their
     representatives  shall  have the  right to make  copies  of such  books and
     records; provided, however, that the foregoing right of access shall not be
     exercisable in such a manner as to interfere  unreasonably  with the normal
     operations and business of such party; and further, provided that, as to so
     much of such  information  as  constitutes  trade  secrets or  confidential
     business  information of such party, the requesting party and its officers,
     directors  and  representatives  will  use due  care to not  disclose  such
     information  except  (x) as  required  by law,  (y) with the prior  written
     consent of such party, which consent shall not be unreasonably withheld, or
     (z) where such information  becomes available to the public  generally,  or
     becomes  generally known to competitors of such party through sources other
     than the requesting  party,  its  Affiliates or its officers,  directors or
     representatives.  Such records may  nevertheless be destroyed by a party if
     such  party  sends to the other  parties  written  notice of its  intent to
     destroy the  records,  specifying  with  particularity  the contents of the
     records to be destroyed.  Such records may then be destroyed after the 30th
     day  after  such  notice  is given  unless  another  party  objects  to the
     destruction  in which case the party  seeking to destroy the records  shall
     deliver such records to the objecting party.

A.   Payments  Received.  The Sellers and Purchaser after the Closing shall hold
     and will promptly  transfer and deliver to the other,  from time to time as
     and when received by them, any cash,  checks with appropriate  endorsements
     (using their best  efforts not to convert such checks into cash),  or other
     property  that they may  receive  on or after the  Closing  which  properly
     belongs to the other party,  including  without  limitation  any  insurance
     proceeds,  and will account to the other for all such  receipts.  Following
     the  Closing,  Purchaser  shall  have the right and  authority  to  endorse
     without  recourse  the  name  of the  Sellers  on any  check  or any  other
     evidences of indebtedness  received by Purchaser on account of the Business
     and the Assets transferred to Purchaser hereunder,  for the sole purpose of
     depositing  such items into accounts over which the Sellers have  signatory
     authority.

A.   Inquiries.  Following the Closing Date, the Sellers will promptly refer all
     inquiries  with  respect  to  ownership  of the Assets or the  Business  to
     Purchaser. The Sellers will execute such documents and financing statements
     as  Purchaser  may  reasonably  request  from time to time to evidence  the
     transfer of the Assets to Purchaser, including any necessary assignments of
     financing  statements.  In addition,  the Sellers shall take all reasonable
     steps necessary to convey to Purchaser any Assets used in the normal course
     of the Business  which are not listed in the Schedules set forth in Section
     1.1(a) of this Agreement.

A.   Covenant  Not to Compete.  In exchange  for the payment by Purchaser to the
     Seller  Shareholders  of Two Million  Dollars  ($2,000,000)  in immediately
     available funds (the "Non-Competition Payment") in accordance with Schedule
     7.6,  and as part of the  transactions  described  in this  Agreement,  the
     Sellers and the Seller  Shareholders each separately agree, for a period of
     five years after the Closing Date,  not to,  directly or  indirectly,  own,
     manage, operate, join or control, or participate in ownership,  management,
     operation or control of, any business whether in corporate,  proprietorship
     or  partnership  form or otherwise as more than a one percent owner in such
     business where such business is competitive with the Business and is within
     a 300-mile radius of the Sellers' facilities used in the Business or in the
     operation  of the  Assets  as of  the  Closing  Date.  The  parties  hereto
     specifically acknowledge and agree that the remedy at law for any breach of
     the foregoing  will be inadequate  and that  Purchaser,  in addition to any
     other relief  available to it, shall be entitled to temporary and permanent
     injunctive  relief  without the  necessity of proving  actual  damage.  The
     Seller and the Seller  Shareholders  acknowledge  that this covenant not to
     compete is being  provided as an  inducement  to  Purchaser  to acquire the
     Business  and the  Assets and that this  Section  7.6  contains  reasonable
     limitations  as to time,  geographical  area and  scope of  activity  to be
     restrained  that do not impose a greater  restraint  than is  necessary  to
     protect  the  goodwill  or other  business  interest  of  Purchaser  in the
     Business.  Whenever  possible,  each provision of this Section 7.6 shall be
     interpreted in such a manner as to be effective and valid under  applicable
     law, but if any  provision of this Section 7.6 is  prohibited by or invalid
     under  applicable law, such provision shall be ineffective to the extent of
     such  prohibition  or  invalidity,   without   invalidating  the  remaining
     provisions  of this Section  7.6. If any  provision of this Section 7.6 is,
     for any reason, judged by any court of competent jurisdiction to be invalid
     or unenforceable,  such judgment shall not affect, impair or invalidate the
     remainder of this Section 7.6 but shall be confined in its operation to the
     provision of this Section 7.6 directly involved in the controversy in which
     such judgment has been rendered.  If the provisions of this Section 7.6 are
     ever  deemed to exceed  the time or  geographic  limitations  permitted  by
     applicable laws, then such provisions shall be reformed to the maximum time
     or geographic limitations permitted by applicable law.

A.   Transition  Period.  During the six-month period following the Closing (the
     "Transition  Period"),  the  parties  shall  operate  the  Business  in the
     following manner:

(a)  Collections. Purchaser's employees shall issue invoices for work in process
     as of the Closing  Date for both the portion of the work  completed  by the
     Sellers  prior to the  Closing  and the  portion of the work  completed  by
     Purchaser thereafter.

(a)  Accounting.   Purchaser's   employees  will  assist  Seller  as  reasonably
     necessary  to close out the  Sellers'  books and  records  relating  to the
     Business.

(a)  Licenses and Permits. The Sellers will continue to cooperate with Purchaser
     in connection with Purchaser's  applications  for the transfer,  renewal or
     issuance of any permits, licenses, approvals or other Authorizations and as
     required to satisfy any regulatory  requirements arising as a result of the
     sale  of the  Business  pursuant  to  this  Agreement,  provided  that  all
     out-of-pocket  expenses  incurred in connection  therewith shall be paid by
     Purchaser.

A.   Accounting Records.  For a five year period following the Closing,  each of
     the Sellers  will use  commercially  reasonable  efforts to take all action
     necessary or appropriate to allow  Purchaser to obtain access to audit work
     papers of the  Sellers'  accountants  for the  immediately  preceding  five
     years,  if Purchaser  requests such access in connection  with the audit by
     Purchaser of the Business for periods preceding the Closing.

A.   Nondisclosure  of  Proprietary  Information.  The  Sellers  and the  Seller
     Shareholders  agree that,  from and after the Closing Date, they and all of
     their  Affiliates  shall  hold in  confidence  and  will  not  directly  or
     indirectly at any time reveal, report, publish, disclose or transfer to any
     person other than  Purchaser any  proprietary  information  relating to the
     Business  or  the  Assets  (the  "Proprietary  Information")  that  is  not
     generally  known to the public or use any  Proprietary  Information for any
     purpose.  The  Sellers  and the Seller  Shareholders  acknowledge  that all
     documents and objects containing or reflecting any Proprietary  Information
     whether  developed by any of the Sellers or by a third party for any of the
     Sellers,  will after the  Closing  Date  become the  exclusive  property of
     Purchaser and be delivered to Purchaser.

A.   Contact  with Former  Employees.  The  Sellers and the Seller  Shareholders
     agree that for a period of five years following the Closing Date, they will
     not solicit for  employment,  directly or  indirectly,  any of  Purchaser's
     employees,  or employees of Purchaser's Affiliates or related companies, or
     any  person  who  has  been so  employed  within  one  year  prior  to such
     solicitation.


                            I. ARTICLE - TERMINATION

A.   Events  of   Termination.   The   obligation  to  close  the   transactions
     contemplated by this Agreement may be terminated as follows:

(a)  by mutual agreement of Purchaser and Sellers;

(a)  by  Purchaser,  if a material  default is made by the Sellers or the Seller
     Shareholders in the observance or in the due and timely  performance by the
     Sellers or the Seller  Shareholders  of any agreements and covenants of the
     Sellers or the Seller Shareholders herein contained, or if there has been a
     breach by the Sellers or the Seller  Shareholders  of any of the warranties
     and  representations  of the  Sellers  or the  Seller  Shareholders  herein
     contained,  and such default or breach has not been cured or waived  within
     20 days of written notice thereof;

(a)  by the  Sellers,  if a material  default is made by Purchaser or DPS in the
     observance or in the due and timely  performance by Purchaser or DPS of any
     agreements and covenants of Purchaser or DPS herein contained,  or if there
     has  been a  breach  by  Purchaser  or DPS  of  any of the  warranties  and
     representations  of Purchaser or DPS herein contained,  and such default or
     breach has not been cured or has not been waived  within 20 days of written
     notice thereof;

(a)  by  Purchaser  or the  Sellers  (provided  the  terminating  party  has not
     materially breached any of its agreements, covenants or representations and
     warranties), if the Closing has not occurred on or before October 15, 1998.

A.   Liability   Upon   Termination.   If  the   obligation  to  consummate  the
     transactions  contemplated by this Agreement is terminated  pursuant to any
     provision of this Article VIII, then this Agreement shall forthwith  become
     void and there shall not be any  liability  or  obligation  with respect to
     this Agreement on the part of Seller or Purchaser  except and to the extent
     such  termination  results from the willful breach by a party of any of its
     representations, warranties or agreements hereunder.

A.   Notice of  Termination.  The parties hereto may exercise  their  respective
     rights of  termination  under this Article VIII only by delivering  written
     notice to that  effect to the other  party on or before the  Closing  Date,
     specifically  describing the factual basis and provisions of this Agreement
     relied upon for such termination.

                           I. ARTICLE - MISCELLANEOUS

A.   Finders' Fees. Neither the Sellers nor the Seller Shareholders have engaged
     any  person to act on their  behalf  in  connection  with the  transactions
     contemplated  by this Agreement who would have any claim against  Purchaser
     or DPS or any of their respective Affiliates for brokerage or finders' fees
     or agent commissions or similar payments.

A.   Expenses. Except as otherwise provided in this Agreement, each party hereto
     shall pay its own expenses incidental to the preparation of this Agreement,
     the carrying out of the provisions of this  Agreement and the  consummation
     of the transactions contemplated hereby.

A.   Assignment and Binding Effect.  This Agreement may not be assigned prior to
     the Closing by any party hereto  without the prior  written  consent of the
     other party; provided,  however,  Purchaser and DPS may assign their rights
     but  not  their   obligations   hereunder  to  any  other  entity  that  is
     controlling,  controlled by or under common  control with Purchaser or DPS.
     Purchaser shall give Sellers prompt written notice of any such  assignment.
     Subject to the foregoing, all of the terms and provisions of this Agreement
     shall be binding upon and inure to the benefit of and be enforceable by the
     successors and assigns of the Sellers, the Seller  Shareholders,  Purchaser
     and DPS.

     communication  which is required or permitted hereunder shall be in writing

A.   Governing  Law.  This  Agreement  shall be  governed  by,  interpreted  and
     enforced in accordance  with the laws of the State of Texas (without regard
     to the choice or conflicts of law provisions of Texas law).

A.   No  Benefit to  Others.  The  representations,  warranties,  covenants  and
     agreements  contained  in this  Agreement  are for the sole  benefit of the
     parties  hereto  and,  in the  case of  Article VI  hereof,  certain  other
     indemnified  parties,  and their heirs,  executors,  administrators,  legal
     representatives, successors and assigns, and they shall not be construed as
     conferring any rights on any other persons.

A.   Entire  Agreement.  This  Agreement  (including  the documents  referred to
     herein)  constitutes the entire  agreement among the parties and supersedes
     any prior  understandings,  agreements,  or representations by or among the
     parties,  written  or oral,  to the extent  they  related in any way to the
     subject  matter hereof.  All Exhibits and Schedules  referred to herein are
     incorporated  herein  in  full  and  are  specifically  made a part of this
     Agreement.

A.   Headings.  All  Section  headings  contained  in  this  Agreement  are  for
     convenience  of reference  only,  do not form a part of this  Agreement and
     shall  not  affect  in any  way  the  meaning  or  interpretation  of  this
     Agreement.

A.   Severability.   Any  provision  of  this  Agreement  which  is  invalid  or
     unenforceable  in any  jurisdiction  shall be  ineffective to the extent of
     such  invalidity  or  unenforceability  without  invalidating  or rendering
     unenforceable the remaining  provisions  hereof, and any such invalidity or
     enforceability   in  any  jurisdiction   shall  not  invalidate  or  render
     unenforceable  such  provision in any other  jurisdiction;  provided if any
     provision  of  this   Agreement  is  held  to  be  illegal,   invalid,   or
     unenforceable  under present or future laws effective  during the effective
     period of this  Agreement,  such provision shall be fully  severable;  this
     Agreement shall be construed and enforced as if such illegal,  invalid,  or
     unenforceable  provision had never comprised a part of this Agreement;  and
     the remaining  provisions of this Agreement  shall remain in full force and
     effect and shall not be affected by the illegal,  invalid, or unenforceable
     provision or by its severance from this Agreement.  Furthermore, in lieu of
     each illegal,  invalid,  or  unenforceable  provision  there shall be added
     automatically  as part of this Agreement a provision as similar in terms to
     such illegal, invalid, or unenforceable provision as may be possible and be
     legal, valid, and enforceable.

A.   Counterparts.  This Agreement may be executed in any number of counterparts
     and any party hereto may execute any such  counterpart,  each of which when
     executed and  delivered  shall be deemed to be an original and all of which
     counterparts   taken  together  shall  constitute  but  one  and  the  same
     instrument. This Agreement shall become binding when all counterparts taken
     together  shall have been executed and  delivered by the parties.  It shall
     not be necessary in making proof of this Agreement as to a party to produce
     or account for any of the other  counterparts  signed by another  party not
     joined in the action.

A.   Construction.  The parties have participated jointly in the negotiation and
     drafting  of this  Agreement.  If an  ambiguity  or  question  of intent or
     interpretation arises, this Agreement shall be construed as drafted jointly
     by the parties and no  presumption  or burden of proof shall arise favoring
     or  disfavoring  any  party  by  virtue  of  the  authorship  of any of the
     provisions of this Agreement.  Any reference to any federal,  state, local,
     or foreign  statute  or law shall be deemed  also to refer to all rules and
     Regulations promulgated thereunder,  unless the context requires otherwise.
     The word "including"  shall mean including without  limitation.  Words used
     herein,  regardless of the number and gender  specifically  used,  shall be
     deemed and construed to include any other number,  singular or plural,  and
     any other gender,  masculine,  feminine or neuter, as the context requires.
     Any  reference to a "person"  herein  shall  include an  individual,  firm,
     corporation,   partnership,   trust,   Governmental  Entity,   association,
     unincorporated  organization  and any other  entity.  Any  references  to a
     Section, Article, Schedule or Exhibit are to sections,  articles,  schedule
     and exhibits to this Agreement, unless otherwise specifically stated.

A.   Waiver. No waiver by any party of any default, misrepresentation, or breach
     of warranty or covenant  hereunder,  whether  intentional  or not, shall be
     deemed to extend to any prior or subsequent default, misrepresentation,  or
     breach of warranty or  covenant  hereunder  or affect in any way any rights
     arising by virtue of any prior or subsequent such occurrence.

A.   Specific Performance.  The Sellers and the Seller Shareholders  acknowledge
     and agree that Purchaser and DPS would be damaged irreparably if any of the
     provisions of this  Agreement  are not  performed in accordance  with their
     specific  terms or otherwise are breached.  Accordingly,  the Sellers agree
     that Purchaser and DPS shall be entitled to an injunction or injunctions to
     prevent  breaches  of the  provisions  of  this  Agreement  and to  enforce
     specifically  this Agreement and the terms and provisions of this Agreement
     in any action  instituted  in any court of the  United  States or any state
     thereof having jurisdiction over the parties and the matter (subject to the
     provisions  set forth in  Section__),  in addition to any other  remedy to
     which they may be entitled, at law or in equity.

A.   Submission to Jurisdiction. Each of the parties submits to the jurisdiction
     of any state or federal court sitting in San Antonio,  Texas, in any action
     or proceeding  arising out of or relating to this Agreement and agrees that
     all claims or  proceedings  will be heard and determined in any such court.
     Each party also agrees not to bring any action or proceeding arising out of
     or  relating  to this  Agreement  in any other  court.  Each of the parties
     waives any defense of  inconvenient  forum to the maintenance of any action
     or proceeding  so brought and waives any bond,  surety,  or other  security
     that might be required of any other party with respect thereto.  Each party
     agrees that a final  judgment in any action or  proceeding so brought shall
     be  conclusive  and may be enforced by suit on the judgment or in any other
     manner provided by law or at equity.

A.   Good Faith.  The parties agree to act in good faith in the  performance and
     enforcement of this Agreement.
B.   Attorneys'  Fees.  If any  arbitration  or  action  at  law  or in  equity,
     including  an action  for  declaratory  relief,  is  brought  to enforce or
     interpret the provisions of this Agreement,  the prevailing  party shall be
     entitled  to recover  reasonable  attorneys'  fees and costs from the other
     party; provided,  however, that no party shall be a prevailing party unless
     such party has recovered  more or paid less as a result of arbitration or a
     final order resulting from judicial  proceedings than the amount offered in
     writing by an opposing party to settle the dispute.

A.   Appointment  of Seller  Shareholders'  Representative.  Each of the  Seller
     Shareholders  hereby  constitutes  and  appoints  Roger D.  Hellums as such
     Seller  Shareholder's duly authorized  representative and  attorney-in-fact
     (the  "Representative")  for all  purposes  of this  Agreement,  the Escrow
     Agreement,  the  Registration  Rights Agreement and all actions to be taken
     hereunder  and  thereunder,   having  the  power  and  authority,   without
     limitation,  (i) to execute and  deliver,  for and on behalf of such Seller
     Shareholder,  the Escrow Agreement,  the Registration  Rights Agreement and
     any other documents, certificates or instruments required to be executed in
     connection with the  transactions  contemplated by this Agreement;  (ii) to
     act for and on  behalf  of such  Seller  Shareholder  with  respect  to any
     dispute  arising  under  this  Agreement,   the  Escrow  Agreement  or  the
     Registration Rights Agreement;  (iii) to exercise any investment  authority
     conferred upon any of the Seller Shareholders individually or as a group by
     the Escrow Agreement; and (iv) to execute and deliver, for and on behalf of
     such  Seller  Shareholder,   all  certificates,   confirmations  and  other
     documents  as  shall  be  necessary  and   appropriate  to  consummate  the
     transactions  provided for in this  Agreement and to fulfill any and all of
     such Seller Shareholder obligations hereunder.  Such power and authority of
     the Representative shall be irrevocable.  Each Seller Shareholder expressly
     acknowledges and agrees that the Representative  shall have no liability to
     such  Seller  Shareholder  for error in judgment  or acts or  omissions  in
     connection herewith, whether or not disclosed and whether or not due to his
     negligence, unless caused by his willful misconduct.

     IN WITNESS WHEREOF, the parties hereto have duly executed this Agreement on
     the date first written.
