            limited  to,  any  acceleration  of  the  vesting  schedules  in any
            employee option agreement triggered by this Agreement).

      Any amounts  deducted by reason of the Purchase Price  Adjustment shall be
      deemed paid by U.S. Filter by virtue of the reduction in consideration for
      the Company Stock.

            (c) "Average Trading Price" means $31.259.

            (d) Any employee stock options to purchase Company Stock outstanding
      and not  exercised  on the Closing Date shall be  automatically  converted

      that the holder of such options  would have been entitled to receive under
      the calculation in Section  1.9(a)(ii) above had the holder converted such
      options  into  Company  Series A  Common  Stock  immediately  prior to the
      Effective Time (with the exercise price being adjusted accordingly), which
      shares  the  Company  has  registered  with the  Securities  and  Exchange

      the Company  and all other  indebtedness  of the  Company  incurred in the
      ordinary course of business,  except for such indebtedness as set forth in

            (a) BENEFIT  PLANS;  COMPANY  PLANS.  Schedule  2.25  discloses  all
      written  and  unwritten  "employee  benefit  plans"  within the meaning of
      Section 3(3) of the Employee  Retirement  Income  Security Act of 1974, as
      amended, and the rules and regulations thereunder ("ERISA"), and any other
      written  and  unwritten  profit  sharing,   pension,   savings,   deferred

      termination  or other plan,  agreement,  contract,  policy,  trust fund or
      arrangement (each, a "Benefit Plan"), whether or not funded and whether or
      not  terminated,  (i)  maintained  or  sponsored  by  the  Company  or any
      Subsidiary,  or (ii) with  respect to which the Company or any  Subsidiary
      (or  the  Stockholders  with  respect  to the  Company)  has  or may  have
      liability or is obligated to contribute,  or (iii) that  otherwise  covers
      any of the current or former employees of the Company or any Subsidiary or
      their  beneficiaries,  or (iv) as to which  any  such  current  or  former
      employees  or  their  beneficiaries   participated  or  were  entitled  to
      participate  or accrue or have  accrued  any rights  thereunder  (each,  a
      "Company Plan").

            (b)  COMPANY  GROUP  MATTERS;  FUNDING.  Neither the Company nor any
      corporation that may be aggregated with the Company under Sections 414(b),
      (c), (m) or (o) of the IRC (the  "Company  Group") has any  obligation  to
      contribute to or any direct or indirect liability under or with respect to
      any Benefit Plan of the type  described in Sections 4063 and 4064 of ERISA
      or Section  413(c) of the IRC.  Neither the Company nor any Subsidiary has
      any liability,  and after the Closing the Company and each Subsidiary will
      not have any  liability,  with  respect to any  Benefit  Plan of any other
      member  of  the  Company   Group,   whether  as  a  result  of  delinquent
      contributions, distress terminations, fraudulent transfers, failure to pay
      premiums  to the  United  States  Pension  Benefit  Guaranty  Corporation,
      withdrawal  liability or otherwise.  No accumulated funding deficiency (as
      defined in Section  302 of ERISA and Section 412 of the IRC exists nor has
      any funding waiver from the IRS been received or requested with respect to
      any Company  Plan or any Benefit  Plan of any member of the Company  Group
      and no excise  or other  tax is due or owing  because  of any  failure  to
      comply with the minimum funding standards of the IRC or ERISA with respect
      to any of such plans.

            (c)  COMPLIANCE.  Each of the Company Plans and all related  trusts,
      insurance  contracts and funds have been created,  maintained,  funded and
      administered in all respects in compliance with all applicable Laws and in
      compliance with the plan document,  trust  agreement,  insurance policy or
      other writing creating the same or applicable  thereto. No Company Plan is
      or is proposed to be under audit or investigation,  and no completed audit
      of any Company Plan has  resulted in the  imposition  of any tax,  fine or
      penalty.

            (d) QUALIFIED PLANS.  Schedule 2.25 discloses each Company Plan that
      purports to be a qualified plan under Section 401(a) of the IRC and exempt
      from United States  federal  income tax under Section 501(a) of the IRC (a

                                       21
<PAGE>

      "Qualified  Plan").  With respect to each Qualified  Plan, a determination
      letter  (or  opinion  or  notification  letter,  if  applicable)  has been
      received from the IRS that such plan is qualified  under Section 401(a) of
      the IRC and exempt from  federal  income tax under  Section  501(a) of the
      IRC. No Qualified  Plan has been amended since the date of the most recent
      such  letter.  No member of the Company  Group,  nor any  fiduciary of any
      Qualified  Plan, nor any agent of any of the foregoing,  has done anything
      that would  adversely  affect the qualified  status of a Qualified Plan or
      the qualified status of any related trust.

            (e) NO DEFINED  BENEFIT PLANS.  No Company Plan is a defined benefit
      plan  within the  meaning of Section  3(35) of ERISA (a  "Defined  Benefit
      Plan").  No Defined  Benefit Plan sponsored or maintained by any member of
      the  Company  Group has been  terminated  or  partially  terminated  after
      September  1, 1974,  except as set forth on Schedule  2.25.  Each  Defined
      Benefit  Plan  identified  as  terminated  on  Schedule  2.25  has met the
      requirement for standard termination of single-employer plans contained in
      Section  4041(b)  of  ERISA.  During  the five year  period  ending on the
      Closing  Date,  no member of the Company  Group has  transferred a Defined
      Benefit  Plan to a  corporation  that  was not,  at the time of  transfer,
      related to the transferor in any manner described in Sections 414(b), (c),
      (m) or (o) of the IRC.

            (f)  MULTIEMPLOYER  PLANS. No Company Plan is a  multiemployer  plan
      within  the  meaning of Section  3(37) or Section  4001(a)(3)  of ERISA (a
      "Multiemployer  Plan").  No member of the Company Group has withdrawn from
      any  Multiemployer  Plan or incurred any withdrawal  liability to or under
      any Multiemployer Plan. No Company Plan covers any employees of any member
      of the Company Group in any foreign country or territory.

            (g)  PROHIBITED  TRANSACTIONS;   FIDUCIARY  DUTIES;  POST-RETIREMENT
      BENEFITS. No prohibited  transaction (within the meaning of Section 406 of
      ERISA and Section 4975 of the IRC) with respect to any Company Plan exists
      or has  occurred  that could  subject the Company to any  liability or tax
      under Part 5 of Title I of ERISA or Section  4975 of the IRC. No member of
      the Company Group, nor any administrator or fiduciary of any Company Plan,
      nor any agent of any of the foregoing,  has engaged in any  transaction or
      acted or failed to act in a manner  that will  subject  the Company or any
      Subsidiary  to any liability for a breach of fiduciary or other duty under
      ERISA or any other  applicable Law. With the exception of the requirements
      of Section  4980B of the IRC, no  post-retirement  benefits  are  provided
      under any Company  Plan that is a welfare  benefit  plan as  described  in
      ERISA Section 3(1).

to the Company or any Subsidiary (other than for employee  reimbursement arising
in the ordinary course of business),  has any contractual  relationship with the
Company or any  Subsidiary  (other  than as an  employee  of the  Company or any
Subsidiary) or is an officer,  director,  employee or consultant of a competitor
of the Company or any Subsidiary.  Except as set forth on Schedule 2.27, neither
the Company nor any  Subsidiary  is indebted or otherwise  obligated to any such
Person,  except for  amounts due under  normal  arrangements  applicable  to all
employees  generally as to salary or reimbursement of ordinary business expenses
not unusual in amount or  significance.  No Related Party will at any time after
the Closing for any reason,  directly or  indirectly,  be or become  entitled to
receive any payment or transfer of money or other  property of any kind from the
Company or any  Subsidiary,  and the Company and each Subsidiary will not at any
time after Closing for any reason, directly or indirectly,  be or become subject
to any obligation of any Related Party.

      2.28 PERMITS. The Company and each Subsidiary holds all "Permits" (defined
to include any permit,  certificate,  license, franchise,  privilege,  approval,
registration  or  authorization  required  under any Law in connection  with the
operation of its assets and business).  All material  Permits of the Company are
listed on Schedule 2.28. Each Permit is valid,  subsisting and in full force and
effect.  The Company and each Subsidiary is in compliance with and has fulfilled
and performed its  obligations  under each Permit,  and, to the knowledge of the
Company, no event or condition or state of facts exists (or would exist upon the
giving of notice or lapse of time or any of them) that could constitute a breach
or default under any Permit. Neither the Company nor any Subsidiary has received
any notice of non-renewal of any Permit.

or the  Stockholders  to be untrue or inaccurate in any material  respect at any
time  prior to the  Closing  Date and (ii) any  failure  of the  Company  or any

            necessary  (1)  to  update  and  keep  such  Registration  Statement
            effective as provided in Section 5.2(a)(i) above, (2) to comply with
            the provisions of the Securities Act with respect to the disposition
            of all Acquisition Shares covered by the Registration  Statement and

            Acquisition  Shares.  Notwithstanding  anything else to the contrary
            contained  herein,  U.S. Filter shall not be required to disclose in
            any amendment or supplement to a registration statement or otherwise
            (x) any confidential  information concerning any matter which is the
            subject of a notice given under  Section  5.2(a)(v) as to which U.S.
            Filter has a bona fide interest in  withholding  disclosure,  or (y)
            historical financial  statements or pro forma financial  information
            required by Regulation  S-X of the  Commission in connection  with a
            business  acquisition  or  disposition  prior to the date  when such
            information  would  otherwise  be  required  to be  filed  with  the
            Commission  (including  extensions  pursuant to Item 7(a)(4) of Form

            conformity  with the  requirements  of the Securities  Act, and such
            other  documents  as  they  may  reasonably   request  in  order  to

                        (iv) Use its best  efforts to  register  and qualify the
            Acquisition Shares covered by  the

            Registration  Statement under such other securities or blue sky laws
            of such  jurisdictions  as  shall  be  reasonably  requested  by the
            Company  Stockholders,  provided  that  U.S.  Filter  shall  not  be
            required  in  connection  therewith  or as a  condition  thereto  to
            qualify to do  business  or to file a general  consent to service of
            process in any such states or jurisdictions; and

                        (v) Notify each Company  Stockholder  at any time when a
            prospectus  relating  thereto is required to be delivered  under the
            Securities  Act, of the  happening of any event as a result of which
            the prospectus  included in the Registration  Statement,  as then in
            effect,  includes an untrue statement of a material fact or omits to
            state a material fact required to be stated  therein or necessary to
            make the  statements  therein  not  misleading  in the  light of the
            circumstances  under which the prospectus is used, and, except for a
            period not to exceed 60 days in each instance where U.S.  Filter has
            a bona fide corporate interest in withholding disclosure or the time
            period for filing  with the  Commission  information  referred to in
            Section 5.2(a)(ii)(y) has not expired,  promptly prepare and furnish
            to such  Company  Stockholders  a  supplement  or  amendment to such
            prospectus,  or otherwise update such prospectus  through the filing
            of a  Current  Report  on  Form  8-K  or  otherwise,  so  that  such
            prospectus  will not contain an untrue  statement of a material fact
            or omit to state any material fact required to be stated  therein or
            necessary to make the statements therein not misleading.

            (b)  Notwithstanding  the  foregoing,   U.S.  Filter  shall  not  be
      obligated to take any action pursuant to this Section 5.2:

                        (i) in any particular  jurisdiction in which U.S. Filter
            would be required to execute a general consent to service of process
            in effecting such registration,  qualification or compliance, unless
            U.S. Filter is already subject to service in such  jurisdiction  and
            except as may be required by the Securities Act; or

                        (ii) if, at such time,  the  Acquisition  Shares held by
            the Company  Stockholders are freely tradeable without regard to any
            volume  restrictions under Rule 144 promulgated under the Securities
            Act.

            (c) All expenses incurred in connection with

      limitation, underwriting discounts, selling commissions and stock transfer
      taxes  applicable  to the  Acquisition  Shares  registered  by the Company
      Stockholders,   fees  and   disbursements   of  counsel  for  the  Company
      Stockholders shall be borne by the Company Stockholders.

            (d) The  obligations of U.S. Filter under this Section 5.2 shall not
      be  transferable by the Company  Stockholders  except in connection with a
      transfer of the Acquisition Shares to a Company Stockholder's decedents or
      spouse (or former spouse in connection  with  dissolution  proceedings) on
      death or otherwise,  or to a trust for their benefit or to an affiliate of
      such Company Stockholder in blocks of not less than 100,000 shares of U.S.
      Filter Common Stock.

            (e) U.S.  Filter  hereby  agrees to indemnify and hold harmless each
      Company  Stockholder,   and  each  such  Company  Stockholder's  officers,
      directors  and  employees,   against  any  losses,   claims,   damages  or
      liabilities,  joint or several,  to which such Company  Stockholder and/or
      person or entity may become subject under the Securities Act or otherwise,
      insofar as such losses,  claims, damages or liabilities (or proceedings in
      respect  thereof) arise out of or are based upon (i) any untrue  statement
      or  alleged  untrue  statement  of  any  material  fact  contained  in any
      registration  statement  filed  pursuant  to  this  Section  5.2,  in  any
      preliminary  prospectus  or  final  prospectus  contained  therein  or any
      amendment or supplement thereto,  (ii) the omission or alleged omission to
      state therein a material  fact required to be stated  therein or necessary
      to make the  statements  therein  not  misleading  or (iii) any failure or
      alleged failure of U.S. Filter to comply with any applicable statute, rule
      or  regulation  in  connection  with  the  registration  statement  or the
      offering,  and will reimburse such Company  Stockholder and/or such person
      or entity  for any legal or other  expenses  reasonably  incurred  by such
      Company  Stockholder  and/or  such person or entity as such  expenses  are
      incurred in  connection  with  investigating  or defending  any such loss,
      claim, damage,  liability or proceeding;  PROVIDED,  that U.S. Filter will
      not be liable in any such case to the extent  that any such  loss,  claim,
      damage or liability  arises out of or is based upon an untrue statement or
      alleged  untrue  statement  or omission or alleged  omission  made in such

      reliance upon and in strict conformity with written information  furnished
      by  such  Company  Stockholder  specifically  for  use in the  preparation
      thereof.

            (f) Each Company  Stockholder,  pursuant to the terms of Article VII
      hereof, hereby agrees to indemnify and hold harmless U.S. Filter, and each
      other person,  if any, who controls U.S.  Filter within the meaning of the
      Securities Act against any losses, claims,  damages or liabilities,  joint
      or several,  to which U.S.  Filter or such  controlling  person may become
      subject under the  Securities  Act or  otherwise,  insofar as such losses,
      claims,  damages or liabilities (or proceedings in respect  thereof) arise
      out of or are based upon any untrue  statement or alleged untrue statement
      of any material  fact  contained,  on the effective  date thereof,  in any
      registration  statement  filed  pursuant  to  this  Section  5.2,  in  any
      preliminary  prospectus or final prospectus  contained therein,  or in any
      amendment  or  supplement  thereto,  or arise out of or are based upon the

      5.3 RESTRICTIONS ON RESALE OF ACQUISITION SHARES. Each Company Stockholder
(and any  assignee of the  Acquisition  Shares)  shall not sell the  Acquisition
Shares in the  public  market,  unless it does so by or  through  Salomon  Smith
Barney,  Inc.,  Donaldson,  Lufkin & Jenrette Securities  Corporation,  Deutsche
Morgan Grenfell or BT Alex Brown or such other nationally  recognized investment
banking firm  satisfactory  to U.S.  Filter in its reasonable  discretion,  and,
further the Company Stockholders shall sell the Acquisition Shares in the public
market in an orderly fashion as will not be materially  disruptive to the market
for U.S. Filter Common Stock.  The Company  Stockholders  shall not transfer the
Acquisition Shares (other than in the public market) to any Person without first
requiring  that  Person  to be bound to U.S.  Filter by the  provisions  of this
Section.

      5.4  POOLING-OF-INTERESTS.  The Company and each Company Stockholder shall
use its or his reasonable  efforts to take, and the Stockholders shall use their
reasonable  efforts  to cause  the  Company  to  take,  all  actions  reasonably
necessary  to allow the Merger to be  accounted  for as a  pooling-of-interests.
Each Company  Stockholder  agrees that he or she will use his or her  reasonable
efforts  to comply  with the  requirements  of the  Commission  concerning  risk
sharing in business  combinations  accounted  for as  pooling-of-interests,  and
pursuant  thereto  will  not sell or in any  other  way  reduce  his or her risk
relative to any shares of U.S.  Filter Common Stock received in the Merger until
such  time as  financial  results  covering  at  least  30 days of  post-closing
combined operations of U.S. Filter have been published.

      5.5  HART-SCOTT-RODINO.  The parties agree to use their reasonable efforts
to take, and the Stockholders  shall use their  reasonable  efforts to cause the
Company to take,  all actions  necessary  to comply with the HSR Act and to make
all necessary filings with applicable authorities thereunder.

Closing Date, U.S. Filter will promptly notify the  Stockholders of any event of
which U.S.  Filter  obtains  knowledge  which has had or has a material  adverse
effect on the  business of U.S.  Filter or any other event of which U.S.  Filter
obtains  knowledge which if known as of the date hereof would have been required
to be disclosed to the Stockholders pursuant to Article III of this Agreement.

      5.7         NONCOMPETITION.

            (a)  RESTRICTIONS ON COMPETITIVE  ACTIVITIES.  Each  Stockholder (it
      being  expressly  understood  that the term  Stockholder  in this  Section
      5.7(a) does not  include  any  affiliates  of BT Capital  Partners,  Inc.)
      agrees  that  after the  Closing  U.S.  Filter  and the  Company  shall be
      entitled to the  goodwill and going  concern  value of the business of the
      Company and the Subsidiaries  (the "Business") and to protect and preserve
      the same to the maximum  extent  permitted by Law. Each  Stockholder  also
      acknowledges  that  the  Stockholders'  management  contributions  to  the
      Business have been uniquely valuable and involve  proprietary  information
      that would be competitively  unfair to make available to any competitor of
      the  Company  or any  Subsidiary.  For these and  other  reasons  and as a
      material  inducement  to U.S.  Filter to enter into this  Agreement,  each
      Stockholder hereby agrees that for a period (the "Noncompetition  Period")
      ending on the later of (i) three years after the date hereof and (ii) with
      respect to David J. Shimmon, three years after he is no longer employed by
      the Company or any  Subsidiary,  each  Stockholder  will not,  directly or
      indirectly,  for such  Stockholder's  own  benefit or as agent for another
      carry on or participate in the ownership, management or control of, or the
      financing  of, or be  employed  by, or  consult  for or  otherwise  render
      services to, or allow such  Stockholder's name or reputation to be used in
      or by any other present or future  business  enterprise that competes with
      U.S.  Filter,  the Company or any  Subsidiary  in  activities in which the
      Company or any  Subsidiary  is engaged as of the Closing  Date,  including
      without  limitation,  in those countries,  states,  counties and cities in
      which the Company or any  Subsidiary  has conducted  business prior to the
      date hereof as set forth on Schedule 5.7 or conducts business prior to the
      termination  of  David  Shimmon's  employment  with  the  Company  or  any
      Subsidiary  for so  long as  U.S.  Filter  or any  person  entitled  to or
      acquiring  ownership of the  goodwill of the  Business or the  Acquisition
      Shares  through  U.S.  Filter  carries  on a  like  business  therein.  In
      addition,  each  Stockholder  agrees  that  such  Stockholder  shall  not,
      directly  or  indirectly,  solicit  or have  any  other  contact  with any
      customers of the Company,  any  Subsidiary or any affiliates or associates
      of such customers until the end of the Noncompetition  Period,  other than
      on behalf of the Company or a Subsidiary. U.S. Filter and each Stockholder
      agree that the  restrictions  contained in this Section 5.7 are a material
      inducement  to U.S.  Filter  to  enter  this  Agreement  but that no other
      separate  compensation or  consideration is being paid with respect to the
      provisions contained in this Section 5.7.



                                       36
<PAGE>

            (b)  EXCEPTIONS.  Nothing  contained in Section  5.7(a)  relating to
      noncompetition  shall limit the right of any Stockholder as an investor to
      continue to hold current  investments  (contingent upon full disclosure to
      U.S.  Filter  in  the  attached  Schedule  5.7(b))  and  to  make  further
      investments in securities of any corporation or limited  partnership  that
      is  registered  on a national  securities  exchange or admitted to trading
      privileges   thereon  or  actively   traded  in  a  generally   recognized
      over-the-counter  market,  provided  such  Stockholder's  equity  interest
      therein does not exceed 2% of the outstanding  shares or interests in such
      corporation or partnership.

            (c) RESTRICTIONS ON SOLICITING  EMPLOYEES.  In addition,  to protect
      U.S.  Filter against any efforts by any  Stockholder to cause employees of
      the  Company  or  any  Subsidiary  to  terminate  their  employment,  each
      Stockholder agrees that until the end of the Noncompetition  Period,  each
      Stockholder will not directly or indirectly (i) induce any employee of the
      Company or any  Subsidiary  to leave the Company or such  Subsidiary or to
      accept any other  employment or position,  or (ii) assist any other entity
      in hiring any such employee.

            (d) SPECIAL  REMEDIES AND ENFORCEMENT.  Each Stockholder  recognizes
      and agrees that a breach by such  Stockholder  of any of the covenants set
      forth in this  Section 5.7 could cause  irreparable  harm to U.S.  Filter,
      that U.S.  Filter's  remedies at law in the event of such breach  would be
      inadequate,  and  that,  accordingly,  in  the  event  of  such  breach  a
      restraining  order  or  injunction  or both  may be  issued  against  such
      Stockholder,  in  addition  to any other  rights  and  remedies  which are
      available to U.S.  Filter.  If this Section 5.7 is more  restrictive  than
      permitted  by the Laws of the  jurisdiction  in which  U.S.  Filter  seeks
      enforcement  hereof,  this  Section  5.7 shall be  limited  to the  extent
      required  to permit  enforcement  under such Laws.  Without  limiting  the
      generality  of the  foregoing,  the  parties  intend  that  the  covenants
      contained in the preceding portions of this Section 5.7 shall be construed
      as a series of separate  covenants,  one for each county and city or other
      location  specified.  Except for geographic  coverage,  each such separate
      covenant  shall  be  deemed  identical  in  terms.  If,  in  any  judicial
      proceeding,  a court shall refuse to enforce any of the separate covenants
      deemed  included in this Section  5.7,  then such  unenforceable  covenant
      shall be deemed  eliminated from these provisions for the purpose of those
      proceedings  to the  extent  necessary  to permit the  remaining  separate
      covenants to be enforced.

      6.1  GENERAL  CONDITIONS.  The  obligations  of the  parties to effect the
Merger shall be subject to the following  conditions unless waived in writing by
all parties:

            (a) NO ORDERS;  LEGAL  PROCEEDINGS.  No law or order shall have been

      entity,  nor shall any action have been  instituted  and remain pending or
      have been  threatened  and  remain so by any  governmental  entity at what

      received from KPMG Peat Marwick, as independent auditors of U.S. Filter, a
      letter,  dated as of the Closing Date, in form and substance  satisfactory
      to U.S. Filter, to the effect that the business combination to be effected

      generally accepted

      with respect to conditions  related to the Company if the Merger is closed
      and consummated  under this Agreement.  No action shall have been taken by
      any governmental  entity,  or any proposal made for any such action by any
      governmental  entity,  which is  reasonably  likely to be put into effect,
      that  would  prevent  U.S.   Filter  from   accounting  for  the  business
      combination to be effected by the Merger as a pooling-of-interests.

            (k)  AFFILIATE  LETTERS.  U.S.  Filter shall have received from each

      Stock shall have exercised  dissenter's rights or rights of appraisal with
      respect to the Merger.

      6.3  CONDITIONS TO OBLIGATIONS  OF THE COMPANY AND THE  STOCKHOLDERS.  The

      adverse change in the business or financial  condition of U.S. Filter from

                                   INDEMNITY

      7.1 SURVIVAL OF REPRESENTATIONS. All representations and warranties of the
parties contained in this Agreement or expressly incorporated herein and therein
by reference shall survive the Closing hereunder and any  investigation  made by
or on behalf of any party hereto until the first  anniversary of the Closing.  A
Claim for indemnification  for breach of a representation,  warranty or covenant
may be brought at any time provided that the representation or warranty on which
such Claim is based  continues  to  survive at the time  notice of such Claim is
given in accordance  with this Article,  and if such notice is given within such
period all rights to  indemnification  with respect to such Claim shall continue
in force and effect.

      7.2         GENERAL INDEMNIFICATION BY COMPANY STOCKHOLDERS.

            (a) GENERAL INDEMNITY.  Each Company Stockholder agrees, jointly and
      severally,  to  indemnify,   defend  and  hold  U.S.  Filter,  Acquisition
      Subsidiary,  the  Company,  each  Subsidiary  and any  director,  officer,
      employee, agent or representative of U.S. Filter,  Acquisition Subsidiary,
      each Subsidiary and the Company  (excluding,  however,  the  Stockholders)
      (collectively  the   "Indemnitees"  and  individually,   an  "Indemnitee")
      harmless  against,  and in respect  of, any and all Claims  suffered by or
      asserted  against  any of  the  Indemnitees  following  the  Closing  Date
      resulting  from,  relating  to or  arising  out of (i) the  breach  by the
      Company  or  any  of the  Stockholders  of  any  of  the  representations,
      warranties,  covenants or agreements contained in or made pursuant to this
      Agreement,  (ii) the operations of the Company and the Subsidiaries  prior
      to the date hereof,  including any and all agreements,  whether written or
      oral, to which the Company or any Subsidiary is or was a party,  (iii) the
      alleged or actual  violation of any Law, rule or regulation,  prior to the
      Closing,  by  the  Stockholders   including,   without   limitation,   any
      Environmental Law, (iv) the generation,  use,  transportation,  treatment,
      storage, release or disposal,  before the Closing, of Hazardous Substances
      at the Real  Property or (v) the presence of Hazardous  Substances  or the
      existence of an  Environmental  Condition at the Real  Property  which was
      present  at such  property  or  facility  at any  time on or  prior to the
      Closing.  The Escrow Shares shall be held by the escrow agent  pursuant to
      the Escrow Agreement until the later of (i) the first  anniversary of this
      Agreement  and (ii) the date that all Claims made by U.S.  Filter prior to
      such first  anniversary have been finally resolved.  Company  Stockholders
      will have no liability  with  respect to the matters  described in clauses
      (i)-(v)  of  this  Section  7.2(a)  unless  the  damages  incurred  by the
      Indemnitees  with  respect to the matters in clause  (i)-(v)  shall exceed
      US$250,000 (the  "Threshold") on a cumulative basis, at which time Company
      Stockholders  shall be liable to Indemnitees  for the total amount of such
      damages  without  regard  to the  Threshold.  In no  event  shall  Company
      Stockholders'  aggregate  liability  to the  Indemnitees  for all  matters
      indemnified  under  this  Section  7.2(a)  exceed the amount of the Escrow
      Shares and the sole recourse for any Company  Stockholder  liability shall
      be to the Escrow Shares.

            (b) PAYMENT.  If any matter as to which an Indemnitee may be able to
      assert a Claim  hereunder has been finally  determined in accordance  with
      this Agreement and the procedures set forth in the Escrow  Agreement,  the
      Indemnitee



                                       42
<PAGE>

      has the  right  to be paid  in an  appropriate  number  of  Escrow  Shares
      (rounded up to the next whole share, if necessary)  taken from all Company
      Shareholders on a pro rata basis. For purposes of determining the value of
      each such share of U.S.  Filter  Common Stock under the Escrow  Agreement,
      such value shall equal the  greater of the  Average  Trading  Price or the
      closing  trading price of U.S. Filter Common Stock as reported by the NYSE
      on the date the Claim has been finally determined.

            (c) LOSSES  NET OF  INSURANCE  BENEFIT.  The amount of any Claim for
      which  indemnification  is provided under this Article VII shall be net of
      any amounts  actually  recovered by the Indemnitee in respect of the Claim
      under  insurance  policies.  Nothing  in this  Section  shall be deemed to
      obligate  any  person to  maintain  any  insurance  or to pursue any claim
      against any insurer or third party (other than to pursue claims against an
      insurer in a manner consistent with Indemnitee's customary practices).

            (d)  LOSSES  NET OF TAX  BENEFIT.  The amount of any Claim for which
      indemnification is provided under this Article VII shall be net of any tax
      benefit  to the  Indemnitee.  The  Stockholders  shall  have the burden of
      showing  actual tax benefit to the  Indemnitee  as a direct result of such
      Claim.

      7.3  CLAIMS  FOR  INDEMNIFICATION.  Whenever  any  Claim  shall  arise for
indemnification under this Agreement, the party entitled to indemnification (the
"Indemnified  Party") shall promptly  notify the other party (the  "Indemnifying
Party")  of  the  Claim  in  writing,  which  notice  shall  include  the  facts
constituting  the basis for such Claim. A failure to notify or to give notice as
hereinabove set forth to the  Indemnifying  Party shall in no case prejudice the
rights of the  Indemnified  Party under this Agreement  unless the  Indemnifying
Party  shall be  prejudiced  by such  failure  and then only to the  extent  the
Indemnifying  Party shall be prejudiced by such failure.  The Indemnified  Party
shall  not  settle  or  compromise  any  Claim by a third  party for which it is
entitled to  indemnification  hereunder without the prior written consent of the
Indemnifying Party (which shall not be unreasonably  withheld) unless (a) a suit
shall have been instituted  against it and (b) the Indemnifying  Party shall not
have taken control of such suit after notification thereof.

      7.4 DEFENSE BY  INDEMNIFYING  PARTY.  In connection  with any Claim giving
rise to  indemnity  under this  Agreement  resulting  from or arising out of any
Claim or legal  proceeding by a party who is not a party to this Agreement,  the
Indemnifying  Party at its sole cost and expense shall assume the defense of any
such 


                                       43
<PAGE>

Claim or legal proceeding with legal counsel  approved by the Indemnified  Party
in its reasonable  discretion  provided that the Indemnified Party hereby agrees
that legal counsel  appointed by any insurance  company providing a defense with
respect to the matter in question shall be acceptable to Indemnified  Party. The
Indemnified  Party shall be entitled to  participate  in (but not  control)  the
defense of any such  action,  with its own  counsel and at its own  expense.  If
after notification  thereof,  the Indemnifying Party does not assume the defense
of any such Claim or litigation  resulting from a Claim in a timely manner so as
not to prejudice the rights of the Indemnified  Party, the Indemnified Party may
defend  against  such  Claim  or  litigation,  in  such  manner  as it may  deem
reasonably  appropriate,  including,  but not limited to, settling such Claim or
litigation,  after giving notice of the same to the Indemnifying  Party, on such
terms as the  Indemnified  Party may deem  appropriate  (within the  exercise of
reasonable  discretion).  The  liability  of the  Indemnifying  Party  shall  be
conclusively  established  by such  settlement by the  Indemnified  Party to the
extent  entered into on the basis of its  reasonable  discretion,  the amount of
such  liability  to  include,  but  not  be  limited  to,  both  the  settlement
consideration and the reasonable costs and expenses,  including attorneys' fees,
incurred by the Indemnified Party in effecting such settlement.

      7.5  NO  CONTRIBUTION  RIGHTS.  The  Stockholders   acknowledge  that  the
Stockholders  shall have no right of contribution from the Company for indemnity
amounts paid by them for breaches of representations and warranties or covenants
of the Company hereunder.

      7.6  ARBITRATION.

            (a) GENERAL PROVISION;  SELECTION OF ARBITRATOR. Except as otherwise
      provided in this  Agreement,  any  controversy  or claim arising out of or
      relating  to this  Agreement  or the  breach  hereof  shall be  settled by
      arbitration  in  Orange  County,  California.  The  arbitration  shall  be
      administered by Judicial  Arbitration and Mediation  Services  ("JAMS") in
      its Orange County office.  The arbitrator  shall be a retired  superior or
      appellate  court judge or Supreme Court Justice of the State of California
      affiliated with JAMS. The Arbitrator shall be chosen by the mutual consent
      of the parties or, if the parties cannot agree,  the  arbitrator  shall be
      chosen by JAMS in accordance with its rules then in effect.  Judgment upon
      the award  rendered by the  arbitrator  may be entered in any court having
      jurisdiction  thereof.  The arbitrator  shall not have any power to alter,
      amend,  modify or change any of the terms of this  Agreement  nor to grant
      any remedy which is either  prohibited  by the terms of this  Agreement or
      not available in a court of law.



                                       44
<PAGE>

            (b)   PROVISIONAL REMEDIES; DISCOVERY.

            Each of the  parties  reserves  the  right  to file  with a court of
      competent   jurisdiction  an  application  for  temporary  or  preliminary
      injunctive  relief,  writ of  attachment,  writ of  possession,  temporary
      protective order and/or  appointment of a receiver on the grounds that the
      arbitration  award to which the  applicant may be entitled may be rendered
      ineffectual  in the  absence  of  such  relief.  The  parties  may  obtain
      discovery in aid of the arbitration to the fullest extent  permitted under
      law,  including  California Code of Civil Procedure  Section 1283.05.  All
      discovery disputes shall be resolved by the arbitrator.

            (c)   APPLICABLE LAW; COSTS.

            All  questions in respect of procedure to be followed in  conducting
      the  arbitration  as  well as the  enforceability  of  this  agreement  to
      arbitrate  which may be resolved by state law shall be resolved  according
      to the law of the State of  California.  Any action brought to enforce the
      provisions of this Section shall be brought in the Orange County  Superior
      Court.  The costs of the  arbitration,  including any JAMS  administration
      fee, and arbitrator's  fee, and costs of the use of facilities  during the
      hearings, shall be borne equally by the parties.


                                 ARTICLE VIII
                     TERMINATION OF OBLIGATIONS; SURVIVAL

      8.1   TERMINATION   OF   AGREEMENT.   Anything   herein  to  the  contrary
notwithstanding,  this  Agreement  and  the  transactions  contemplated  by this
Agreement  shall  terminate if the Closing does not occur on or before the close
of business on January 31, 1998 unless  extended by mutual consent in writing of
U.S. Filter,  Acquisition  Subsidiary,  the Company and the Stockholders and may
otherwise  be  terminated  at any time  before the  Closing as follows and in no
other manner:

            (a)   MUTUAL CONSENT.  By mutual consent in writing of U.S.
      Filter and the Company.

                                       45
<PAGE>

            (b)  CONDITIONS  TO  U.S.  FILTER'S  AND  ACQUISITION   SUBSIDIARY'S
      PERFORMANCE NOT MET. By U.S.  Filter or Acquisition  Subsidiary by written
      notice to the Company and the Stockholders if any event occurs which would
      render  impossible  the  satisfaction  of one or  more  conditions  to the
      obligations of U.S.  Filter and  Acquisition  Subsidiary to consummate the
      transactions contemplated by this Agreement as set forth in Section 6.2.

            (c)  CONDITIONS TO THE COMPANY'S AND THE  STOCKHOLDERS'  PERFORMANCE
      NOT MET. By the Company by written notice to U.S.  Filter and  Acquisition
      Subsidiary  if  any  event  which  occurs  would  render   impossible  the
      satisfaction  of the  conditions to the  obligations of the Company or the
      Stockholders to consummate the transactions contemplated by this Agreement
      as set forth in Section 6.3.

      8.2 EFFECT OF TERMINATION. In the event this Agreement shall be terminated
pursuant to Section  8.1,  all  further  obligations  of the parties  under this
Agreement and the Other Agreements shall terminate  without further liability of
any party to another;  provided that the obligations of the parties contained in
Sections  10.3 and 10.8 and Article VII shall  survive any such  termination.  A
termination  under  Section  8.1(b) or (c) shall  not  relieve  any party of any
liability for a breach of, or for any misrepresentation under this Agreement, or
be deemed to constitute a waiver of any  available  remedy  (including  specific
performance if available) for any such breach or misrepresentation.


                                  ARTICLE IX
                            STOCKHOLDERS AGREEMENT

      In order to induce U.S Filter to enter into this Agreement, and as further
consideration for the promises and the mutual covenants herein, the Stockholders
further represent, warrant and covenant with U.S. Filter as follows:

      9.1  VOTING.  Stockholders  will vote or cause to be voted  all  shares of
capital  stock of the Company owned of record or  beneficially  owned or held in
any capacity by any of them or under any of their control in favor of the Merger
and other transactions provided for in or contemplated by this Agreement.

      9.2 OWNERSHIP. As of the date hereof,  Stockholders' only ownership of, or
interest in, equity  securities or  convertible  debt  securities of the Company
consists solely of the interests described in Schedule 9.2 hereto (collectively,
the "Company Shares").



                                       46
<PAGE>

      9.3 RESTRICTION ON TRANSFER.  Stockholders will not sell, transfer, pledge
or otherwise  dispose of any of the Company  Shares or any  interest  therein or
agree to sell,  transfer,  pledge or otherwise  dispose of any of the Company or
any interest  therein  prior to Closing or the  termination  of this  Agreement,
without U.S. Filter's express written consent.

      9.4  INVESTMENT  INTENTION.  Each  Stockholders  has no  present  plan  or
intention to sell, exchange,  or otherwise dispose of a number of shares of U.S.
Filter Common Stock received in the Merger that would reduce such  Stockholder's
ownership of U.S.  Filter Common Stock to a number of shares having a value,  as
of the  Effective  Time,  of less  than 50  percent  of the  value of all of the
formerly outstanding Company Stock held by such Stockholder as of the same date.
For  purposes  of this  representation,  dissenters'  shares  of  Company  Stock
exchanged for cash in lieu of fractional shares of U.S. Filter Common Stock will
be treated as outstanding Company Stock on the Effective Time. Moreover, Company
Stock and U.S.  Filter Common Stock held by  Stockholders  and  otherwise  sold,
redeemed, or disposed of prior or subsequent to the Merger will be considered in
making this representation.

      The foregoing shall not prevent any the Stockholders whose shareholding in
U.S.  Filter  Common Stock will be less than 1% of the U.S.  Filter Common Stock
issued  and  outstanding  immediately  after the  Effective  Time from  selling,
exchanging or otherwise disposing of them; provided however, that any such sale,
exchange  or other  disposition  (i) shall  comply  with all  federal  and state
securities  laws,  (ii)  shall in no event be made at any time or in any  manner
which may preclude or prevent (a) U.S.  Filter from accounting for the Merger as
a pooling-of-interests, including before U.S. Filter publicly releases its first
report of financial  statements including the combined financial results of U.S.

      9.5 TERMINATION OF AGREEMENTS. Stockholders and the Company, to the extent
they are  parties,  beneficiaries  or have rights  under any and all  agreements
among stockholders,  including those set forth on Schedule 9.5, hereby terminate
such  agreements as of the Effective Time.  Stockholders  hereby agree that upon
termination  all  obligations  under  these  agreements  will  be  automatically
discharged and that Stockholders,  their heirs,  directors,  officers,  personal
representatives,  assignees,  and  transferees  fully and  forever  release  and
forever  discharge  the  Company  and  its  associates,   owners,  stockholders,

successors,  heirs, assigns, agents, directors,  officers, partners,  employees,
representatives,  trustees, lawyers, insurers,  sureties, and all persons acting
by, through,  under, and in concert  therewith,  or any of them, of and from any
and all  cause  or  causes  of  action,  suits,  claims,  demands,  obligations,
liabilities,  damages, liens, contracts,  agreements,  promises,  laws, costs or
expenses of any nature  whatsoever,  whether known or unknown,  whether fixed or
contingent,  whether at law or in equity, arising out of or in any way connected
or related to the above described  agreements or the offer, sale, or issuance of
any Company  securities  or otherwise  arising out of or in any way connected or
related to the offer, sale or issuance of any Company  securities.  Stockholders
acknowledge and intend the  consequences of the foregoing  release to apply even
as to claims for damages that may exist,  and which,  if known would  materially
affect Stockholders'  decision to execute this Agreement,  regardless of whether
Stockholders' lack of knowledge is the result of oversight, error, negligence or
any other cause.

      9.6 TERMINATION. Solely with respect to Sections 9.1, 9.2. and 9.3 of this
Agreement,  Stockholders'  obligations  thereunder will terminate on January 31,
1998 unless extended in accordance  with the terms of this  Agreement,  in which
event  Stockholders'  agreement and obligations  will terminate on such extended
date.  Notwithstanding  the  foregoing,  if this Agreement were to be terminated
earlier in accordance with its terms (except in event of a termination by reason
of the Company's  defaults,  misrepresentation  or breach),  this Article IX and
Stockholders'  obligations  hereunder will also terminate  concurrently with the
termination of this Agreement.

      9.7 EFFECTIVE DATE; SUCCESSION REMEDIES. Upon U.S. Filter's acceptance and
execution of this  Agreement,  this Article IX shall  mutually  bind and benefit
U.S. Filter and the  Stockholders,  any of Stockholders'  heirs,  successors and
assigns and any of U.S Filter's successors.  Stockholders agree that in light of
the inadequacy of damages as a remedy,  specific  performance shall be available
to U.S Filter,  in addition to any other  remedies U.S.  Filter may have for the
violation of this Article IX.

      9.8 NATURE OF HOLDINGS;  SHARES. All references made in this Article IX to
Stockholders'  holdings of the Company Shares shall be deemed to include Company
Shares held or controlled by any of the Stockholders,  individually, jointly (as
community property or otherwise),  or in any other capacity, and shall extend to
any securities issued to any Stockholders in respect of the Company Shares.

may be  expressly  waived in  writing  by the other  party,  but such  waiver or

      United States Filter Corporation Announces The Acquisitions of Kinetics
                        Group Inc. And Other Transactions


PALM DESERT,  Calif.,  Jan. 5 -- United States Filter  Corporation  (NYSE:  USF)
announced  today  that it has  signed a  definitive  agreement  to  acquire  The
Kinetics Group, Inc. for approximately  $170,000,000 plus outstanding debt. U.S.
Filter will issue  shares of its common  stock to the  stockholders  of Kinetics
pursuant to a private  placement.  The  transaction  will be accounted  for as a
tax-free  pooling of interests.  The transaction is subject to Hart Scott Rodino
clearance.

Kinetics is the leading U.S.  provider and  manufacturer of  sophisticated  high
purity process piping systems and is also a major U.S. integrator of high purity
water,  fluid and gas handling systems that are critical to the  pharmaceutical,
biotechnology and microelectronics industries. Kinetics offers turnkey solutions
to its customers,  who are  industry-leading  manufacturers  in their respective
market areas. Kinetics revenues were over $400,000,000 for its fiscal year ended
September 30, 1997.

"The combination of Kinetics'  project  management  expertise and U.S.  Filter's
equipment   and   technology   expertise   will   provide  the   pharmaceutical,
biotechnology  and  microelectronics  markets with their first fully  integrated
turnkey process water capability," said Richard J. Heckmann, Chairman, President
and CEO of U.S. Filter. "With the reduction in cycle times and the drive towards
single  source  capabilities,  we believe  the  combination  of U.S.  Filter and
Kinetics  will be truly  unique in our  industry and will provide a platform for
the  integration  of many  other  U.S.  Filter  products  including  wastewater,
filtration devices and other process equipment," he said.

David  Shimmon,  CEO of The Kinetics  Group,  Inc.,  stated "We are delighted to
become part of the U.S.  Filter team. The merger of U.S. Filter and The Kinetics
Group is an exciting  opportunity  for our customers and  employees.  It greatly
expands our  geographical  reach,  our integrated  system  capabilities  and our
ability  to  aggressively  pursue  corporate  development  activities  that will
strengthen  our position as the leading  provider of high purity  process piping
systems.  Furthermore,  our employees  will benefit from the  combination of two
dynamic organizations."

With Kinetics' 19 offices across the United States,  U.S. Filter  indicated that
the integration of the two companies will begin immediately and that it expected
Kinetics to be additive to its  earnings in the fiscal year  beginning  April 1,
1998.  U.S.  Filter  also  announced  that for its third  fiscal  quarter  ended
December

31,  1997,  the Company  completed  24  acquisitions  totaling  $865,000,000  in
annualized  revenues.  The total  includes  Memtec  Limited,  Kinetics and other
transactions in virtually every segment of its businesses.  The Company said the
cumulative  purchase  price paid for the above  transactions  was  approximately
$770,000,000 in cash, stock and assumed debt.

With  annualized  revenues  before the above  acquisitions of over $2.6 billion,
U.S.  Filter  is the  leading  global  provider  of  industrial,  municipal  and
residential water and wastewater treatment systems,  products and services, with
an  installed  base that U.S.  Filter  believes  is the  largest  worldwide.  In
addition,  U.S.  Filter has the industry's  largest network of sales and service
facilities  through over 600 locations  including 77 manufacturing  plants in 31
countries.  U.S. Filter is also a leading provider of outsourced water services,
including the operation of water and  wastewater  treatment  systems at customer
sites.  It is  also  actively  involved  in  the  development  of  privatization
initiatives  for municipal water  treatment  facilities in the U.S.,  Mexico and
Canada.
