           instructions to the Bank to release the Relevant Funds to Seller 1.


     4.5.4 Purchaser  shall  not  be  obliged  to  issue  written  instructions
           pursuant to Section 4.5.3 above to the extent that he has:

     (i)   notified  Seller 1 prior to the expiry of the relevant Escrow Period

           based and the amount of the Warranty Claim); and

               notification pursuant to (i) above,  commenced legal proceedings
               (Klageerhebung) to pursue such Warranty Claim.

           the case of (i) above,  to the amount  notified  to Seller 1 and, in
           the  case  of (ii)  above,  to the  amount  claimed  in  such  legal
           proceedings.


     4.5.5 To the extent  that any  Warranty  Claim  shall have been  agreed by
           Purchaser  and  Seller  1  or  determined  by  a  judgement  of  the
           competent court,  Purchaser and Seller 1 shall immediately upon such
           agreement or determination  issue joint written  instructions to the
           Bank to pay the  amount  of such  Warranty  Claim  from  the  Escrow
           Account to Purchaser.


     4.5.6 In the event of an adjustment to the Cash Price  pursuant to Section
           4.3.2 (ii) or (iii)  above,  any amounts to be so released  shall be
           released  from the  Relevant  Funds set out in Section  4.5.3  (iii)

           from the Escrow Account  forthwith upon  determination of the amount
           of the adjustment to the Cash Price.


     4.5.7 Each of Purchaser and Seller 1 undertake to issue  instructions  for

                                      S 5
                 Preparation and Audit of Financial Statements


5.1  Seller 1 and Purchaser  will cause Walter Hund and Dr.  Freimut  Vizethum,
     the  Managing  Directors  of  Friadent,  to prepare  financial  statements
     (balance  sheet,  profit  and  loss  account  and the  annex  thereto)  of
     Friadent as of December  31, 2000 or such other date as is agreed  between
     the   Parties  in  writing   (hereinafter   referred  to  as  "  Financial
     Statements")  by no later than  February 15, 2001.  Seller 1 and Purchaser
     shall further cause Walter Hund and Dr.  Freimut  Vizethum to procure that
     the Subsidiaries  prepare financial  statements as of such date and within
     the same period of time.


5.2  The  Financial  Statements  shall be  prepared  in  accordance  with those
     generally  accepted  accounting  principles  the  Company  is  subject  to
     (German GAAP) and to be consistently  applied  maintaining full accounting
     and valuation  consistency.  The financial  statements of the Subsidiaries
     shall be prepared in accordance with those generally  accepted  accounting
     principles applicable to each of them, to be consistently applied.


5.3  The  Financial   Statements  shall  be  audited  by  Friadent's  appointed
     auditor,  Dr. Glade,  Konig und Partner GmbH  (hereinafter  referred to as
     "Company's  Auditor").  In addition,  the Company's  Auditor shall compute
     the adjustment to the Cash Price pursuant to Section 4.3 above (if any).


5.4  Each of the Sellers and Purchaser  shall have the right,  at its own cost,
     to review  (uberprufen) the audited Financial  Statements either itself or
     by an auditor . Sellers and Purchaser  shall have  completed  their review
     of the audited  Financial  Statements  no later than 4 weeks after receipt
     of the audit  report of  Company's  Auditor  on the  Financial  Statements
     (hereinafter referred to as "the Audit Report").


5.5  Each of the Sellers and Purchaser and/or their  respective  auditors shall
     following  the  Closing  Date have full access to  management,  employees,
     accounts and other  financial  information  of Friadent and working papers
     of the  Company's  Auditor as is  reasonably  necessary for the purpose of
     this Section 5. Each of Sellers and Purchaser  shall procure that Friadent
     gives such access and that the  Company's  Auditor  will be released  from
     his  professional  secrecy  obligation  towards  each of the  Sellers  and
     Purchaser and their respective  auditors and that Friadent  authorizes and
     instructs the  Company's  Auditor to grant  unlimited  access to the other
     auditors  with  respect to his  working  papers and audit  materials.  The
     Company's  Auditor will grant unlimited  access to the other auditors also
     with  respect  to  working  papers and audit  materials  for the  previous
     fiscal years of Friadent.


5.6  If Sellers or their  auditors on the one hand or Purchaser or his auditors
     on the other hand do not notify the  Purchaser or Sellers (as the case may
     be) within 4 weeks from  receipt of the Audit  Report that any of them has
     any objections against such report,  specifying in writing each individual
     item  and  the  reasons  for  the  objections  thereupon,   the  Financial
     Statements as audited by the Company's  auditor shall become final for the
     purpose of the  computation  of the  adjustment to the Cash Price (if any)
     in accordance with Section 4.3 above.


5.7  In the event that  Sellers or their  auditors on the one hand or Purchaser
     or his  auditors  on the other hand  notify  Purchaser  or Sellers (as the
     case may be) within 4 weeks from  receipt of the Audit  Report that any of
     them has any  objections  against such report,  specifying in writing each
     individual  item  and  the  reasons  for  the  objections  thereupon,  the
     auditors of Sellers on the one hand and the  auditors of  Purchaser on the
     other hand shall then try to reach an  agreement  of the  adjustments  (if
     any)  required to the  Financial  Statements  within  seven (7) weeks from
     receipt of the Audit  Report.  To the extent that the  auditors of Sellers
     on the one hand and the  auditors  of  Purchaser  on the other hand do not
     reach any such  agreement,  the Sellers and the Purchaser  shall use their
     best efforts jointly to solve any possible  differences of opinion between
     the auditors within one (1) additional week.


5.8  If no agreement can be reached,  Sellers and  Purchaser  shall decide upon
     the nomination of an expert  arbitrator  (Schiedsgutachter)  whose opinion
     shall be binding for all




                                      161


    parties  involved.  If no mutual  agreement  can be reached  regarding  the
     person of the expert  arbitrator,  the expert  arbitrator  who has to be a
     German chartered  accountant  (Wirtschaftsprufer)  and a member of a major
     international  accounting firm and whose  appointment  shall be subject to
     such expert  confirming  that he will  deliver his ruling  within the time
     period stated below,  shall be appointed by the President of the Institute
     of Chartered  Accountants in Germany upon formal request by either Sellers
     or Purchaser.  The expert  arbitrator shall be bound by the accounting and
     valuation  principles  agreed upon in this  Agreement and shall render its
     written  ruling on the disputed  items of the Financial  Statements  which
     shall in no event  exceed  the  scope  and  limits  set by the  objections
     raised  under  Section 5.7 to Sellers and  Purchaser  within not more than
     six (6)  weeks  from  nomination.  The  expert  arbitrator  shall,  in his
     equitably exercised  discretion,  decide on the distribution of the expert
     arbitrators'  expenditures  and  remunerations  taking  into  account  the
     success or failure of the respective Party.


5.9  Any  agreement  reached  by the  auditors  and/or by the  Sellers  and the
     Purchaser in  accordance  with Section 5.7 and/or any ruling by the expert
     arbitrator in  accordance  with Section 5.8 shall be  incorporated  in the
     Financial  Statements which shall upon such incorporation become final for
     the purpose of the  computation  of the  adjustment  to the Cash Price (if
     any) in accordance with Section 4.3 above.

6.1  Neither Seller 1 nor Seller 2 give any  representations  and/or warranties
     on their own  behalf  of  whatsoever  kind  and/or  of  whatsoever  nature
     including,  without  limitation,  any  representations  and/or  warranties
     relating  to  legal  defects   (Rechtsmangel)   and/or   defects  in  kind
     (Sachmangel).  In  particular,  neither  Seller 1 nor  Seller 2 gives  any
     representation  and/or warranty as to the identity of Manfred Schmider und
     Dr. Ing. Klaus Kleiser Finanz  Holding GbR with S & K  Finanzholding  GbR.
     Any rights and claims of  Purchaser  for legal  defects or defects in kind
     against  Seller  1  and/or  Seller  2  are  hereby  expressly  waived  and
     excluded.


6.2  The same applies  with  respect to any other  liability of Seller 1 and/or
     Seller 2 in relation to this  Agreement or the  transactions  contemplated
     hereby;  any claims  against  Seller 1 and/or Seller 2 including,  without
     limitation,  any claims under  precontractual fault (culpa in contrahendo)
     or  breach  of  contract  (pVV)  and/or  the  right to  reduce  the  Total
     Consideration or any part thereof (Minderung) and/or to




                                      162


     withdraw from this Agreement  (Wandlung)  and/or to rescind this Agreement
     (Rucktritt)  and/or  any  liability  of  Seller 1 and/or  Seller 2 in tort
     (Deliktshaftung)  shall hereby be expressly waived and excluded,  provided
     however  that  this  Section  6.2  shall  not  apply  to the  extent  that
     Purchaser can prove fraudulent  behaviour or wilful misconduct of Seller 1
     and/or Seller 2,  respectively.  The  obligations  of Seller 1 pursuant to
     Section 4.5 shall remain unaffected.


6.3  Notwithstanding  the aforesaid,  any liability of Seller 1 and/or Seller 2
     under this  Agreement  shall be several.  In  particular,  any  fraudulent
     behaviour or wilful  misconduct  of Seller 1 and/or  Seller 2 shall not be
     invoked against the other Seller.


6.4  For the  avoidance  of doubt,  any  Warranties  given for and on behalf of
     Warrantor  pursuant to Section 7.1 below cannot be invoked  against and do
     not  create  any  liability  against  Sellers  or any  of  them.  For  the
     avoidance of doubt,  the  obligations  of Seller 1 pursuant to Section 4.5
     shall remain unaffected.

           referred to as the "Subsidiary  Shares").  To the best of Seller 1 s
           knowledge  there  are no  rights  of  Sellers  or third  parties  to

           principles  consistently  applied by the  respective  members of the

           such  companies in accordance  therewith.  Friadent has not made any
           dividend distributions after December 31, 1998.

           with all material legal and regulatory  provisions applicable to the
           Friadent Group in connection  with its business.  To Seller 1's best
           knowledge,  and on the  basis  of the  presently  existing  laws  no
           material  additional  conditions  (gesetzliche  Auflagen)  are to be
           expected  in the  near  future  in  relation  to  such  business  as
           presently conducted.

           administrative  agencies  or  arbitration  tribunals  in  which  any
           individual claim or any series of product  liability claims asserted
           exceed DM 100,000,00.  To Seller 1's best knowledge there is also no
           threat of such proceedings.


     7.1.9 To Seller  1's best  knowledge,  except as listed in  Exhibit  7.1.9
           there are no  circumstances  in  existence  which  could  materially
           affect the  business of the  Friadent  Group as carried on as at the
           date of this  Agreement  (save to the extent  that the same would be
           likely  to  affect  to a  similar  extent  generally  all  companies
           carrying on similar businesses).


     7.1.10All powers of attorney for  individuals  who are not  employees of a
           company of the  Friadent  Group shall  expire on the  Closing  Date,
           except for those listed in Exhibit 7.1.10.


     7.1.11.No investment grants or subsidies shall be repayable as a
           consequence of the performance of this Agreement or any events

            (hereinafter  referred to as "the  Properties")  is fully  listed in

            are identified in Exhibit 7.1.12. There are no pending registrations
            being applied for.

               arrangements  which cannot be  terminated  on a day to day basis
               without cost.


7.2  Warrantor  shall not be liable  for a breach of any of the  Warranties  to
     the extent that Seller 1 discloses  to Purchaser in writing with a copy to
     Warrantor  between  signing of this  Agreement  and the  Closing  Date any
     facts,  circumstances  or events which could constitute a breach of any of
     the  Warranties.  The same shall apply to those facts,  circumstances  and
     events  which  are  otherwise  known by  Purchaser  as at the date of this
     Agreement and/or as at the Closing Date.


7.3  Where any  warranty  herein is made at "Seller  1's best  knowledge",  the
     knowledge  of  Seller  1  shall  be  limited  to the  knowledge  of any of
     Messrs. Walter Hund and Dr.  Freimut Vizethum.

7.4  Sellers,  Purchaser and  Warrantor  acknowledge  and agree that  Purchaser
     does not request any additional Warranties to those set out herein.


7.5  As used in this  Agreement,  the terms  "warranty" and "guarantee" and the
     verbs  "to  warrant",   "to  guarantee"  refer  to  separate  promises  of
     guarantee pursuant to Section 305 of the German Civil Code (BGB).

                            Liability of Warrantor


8.1  Rights of Purchaser for Breach of Warranty


     8.1.1 In the event that any of the Warranties  given above under Section 7
           is partially or entirely incorrect,  Purchaser shall be entitled to,
           subject to the other provisions of this Section 8:


           (i) in the case of a breach of any of the  Warranties  contained  in
               Section  7.1.1  and/or  7.1.2 as a direct  consequence  of which
               title to the Shares does not pass to  Purchaser  on Closing,  to
               reclaim the Total Consideration  against assignment to Warrantor
               of its  Reimbursement  Claim,  provided  however that  Purchaser
               shall be  entitled  to withhold  such  assignment  to the extent
               that Purchaser's claim for repayment of the Total  Consideration
               is not satisfied; and


           (ii)in the  case of a  breach  of any of the  other  Warranties,  to
               reduce,  subject to the  limitations  set forth in  Section  8.5
               (ii) the Total  Consideration  by an amount equal to the damages
               resulting  from the violation of the  respective  Warranty,  the
               amount  equalling such damages  bearing  interest at a rate of 6
               per cent. per annum from the day the  respective  Warranty Claim
               is asserted by Purchaser  against Warrantor by issuance of legal
               proceedings  (Klageerhebung)  until the day of  payment  of such
               Warranty  Claim to the  Purchaser  with  interest  being due for
               payment  together  with  payment of the  principal  amount;  any
               reduction  pursuant  to  this  Sub-Section  (ii)  shall  be made
               against the amount set out in Section 4.1 (i) above.


     8.1.2 If tax  assessments  for the  Friadent  Group are  issued or amended
           with  respect to any period of time prior to the Closing  Date,  any
           resulting




                                      167


           additional tax liabilities  allocable to the period of time prior to
           the Closing Date including  interest  thereon  falling due after the
           Closing  Date shall be borne by  Warrantor.  This shall not apply to
           the  extent  that such tax  liabilities  had their  origin in a mere
           shifting  of taxable  profits to another  taxable  year and there is
           correspondingly  less  tax  in the  following  six  years.  However,
           interest shall be computed on such  additional  taxes paid until the
           dates of their  recovery  at the  interest  rate of 6 % and shall be
           considered as damage.


8.2  Provision and Compensation


     Purchaser  shall not be  entitled  to base any claims  under  Section  8.1
     above on any facts, circumstances and events to the extent that:


     (i)   any  provisions  have been made in the Financial  Statements for any
           such facts, circumstances and events; and/or


     (ii)  such claims will be  compensated  by an insurance  company under any
           insurance policy of the Friadent Group; and/or


     (iii) Purchaser  has been  compensated  for any such facts,  circumstances
           and events by the  adjustment of the Cash Price  pursuant to Section
           4.3 (if any).


8.3  Remedial Action and Mitigation


     If any facts,  circumstances  or events  occur  giving rise to a claim for
     breach of Warranty, then:


     (i)   Warrantor  will be afforded a reasonable  opportunity  not exceeding
           12 weeks to remedy the matter  which is the  subject of the claim to
           the extent  that the facts,  circumstances  or events are capable of
           being so remedied; and


     (ii)  Purchaser  shall, and shall procure that the members of the Friadent
           Group  shall,   co-operate   with   Warrantor  to  ensure  that  all
           reasonable  steps are taken to mitigate  any loss giving rise to the
           claim.


     Purchaser  shall in particular  inform  Warrantor in writing without undue
     delay in case third  parties  assert or threaten  to assert  claims of any
     kind  against  the  Friadent  Group,  Purchaser  or  companies  related to
     Purchaser which could result in a liability




                                      168


     of  Warrantor  according  to this  Agreement.  Purchaser  shall  cause the
     Friadent  Group to make available to Warrantor all  appropriate  documents
     and supply all appropriate  information and shall give Warrantor access to
     the books and documents  belonging to the business of the Friadent  Group,
     to the  extent  that  this is  necessary  to  defend  or  remedy  any such
     asserted claims.


8.4  De minimis


     Purchaser shall be entitled to assert claims under this Agreement only if:


     (i)   an individual  claim exceeds  DM 75,000.00  (in words:  German Marks
           seventy-five thousand), and


     (ii)  the sum  total of  individual  claims  exceeds  DM 1,000,000.00  (in
           words: German Marks one million).


     Where the  limits  set out in  Section  8.4 (ii) are  exceeded,  Purchaser
     shall be  entitled  to assert  claims for the sum of the excess  over (ii)
     only. In any event,  Purchaser  shall be obliged in the first  instance to
     seek  satisfaction  of its claims out of the funds contained in the Escrow
     Account  from time to time and shall only be  entitled  to claim  payments
     from  Warrantor  to the  extent  that the funds  contained  in the  Escrow
     Account from time to time are insufficient to meet Purchaser's claims.


8.5  Limitation by amount


     Claims  asserted  for breach of  Warranties  and/or for damages in lieu of
     specific performance under this Agreement shall be limited as follows:


     (i)   claims under  Section  7.1.1 and/or 7.1.2  affecting the transfer of
           title to the Shares at  Closing to 100 % of the Total  Consideration
           (as adjusted pursuant to Section 4.3 above); and


     (ii)  claims   under   all  other   Warranties   to  25  %  of  the  Total
           Consideration (as adjusted pursuant to Section 4.3 above);


     provided  however that the sum of (i) and (ii) shall in no event exceed an
     amount equal to 100 % of the Total  Consideration (as adjusted pursuant to
     Section 4.3 above).




                                      169


8.6  Limitation Period


     All  claims  of  Purchaser   under  this  Agreement   including,   without
     limitation,  any Warranty  Claims and/or  claims for specific  performance
     shall become  statute-barred  (Verjahrung) within 18 months as of the date
     of this Agreement except for the following claims:


     (i)   claims  made under  Section 7.1.1  and/or  7.1.2 to the extent  that
           they are for  failure to  transfer  title to the Shares at  Closing,
           which shall become  statute-barred  within 10 years from the date of
           this Agreement; and


     (ii)  claims  relating  to  tax  obligations,   customs   obligations  and
           obligations  relating to levies and social  security  obligations of
           the  Friadent  Group,  which shall  become  statute-barred  within 6
           months from the date on which the respective  assessment becomes res
           iudicata.


8.7  Right to rescind


     In the event  that  between  signing  of this  Agreement  and  before  the
     Closing Date one or more  breaches of Warranty  are  disclosed by Seller 1
     to Purchaser in accordance with Section 7.2 above:


     (i)   which will not be fully  compensated  by the  adjustment to the Cash
           Price in accordance with Section 4.3; or


     (ii)  which Warrantor is not able to remedy (objektive  Unmoglichkeit) nor
           willing to be held  liable for in  accordance  with  Section 8 above
           (the intention to being held so liable having to be  communicated to
           Purchaser  in  writing  within 72 hours from the  disclosure  of the
           breach having been made to Purchaser);


     then  Purchaser  shall be entitled to rescind  this  Agreement  by written
     declaration  of  rescission  to be  received  by  Sellers no later than 48
     hours  after the expiry of the 72 hour  period set out in (ii)  above.  In
     addition,  Purchaser  shall be entitled to so rescind the Agreement if the
     disclosure  is such  that a prudent  business  man as  purchaser,  in good
     faith and  notwithstanding  the  remedies  set out in (i) and (ii)  above,
     could not reasonably be expected to proceed to Closing.




                                      170


8.8  No other liabilities of and remedies against Warrantor


     Any further  rights and claims of  Purchaser of  whatsoever  nature and on
     whatsoever legal basis, in particular,  without  limitation,  any Warranty
     Claims of Purchaser  other than  expressly  agreed upon in this  Agreement
     are hereby expressly  waived and excluded.  This shall in particular apply
     to any  claims  based on  precontractual  fault  (culpa  in  contrahendo),
     breach of  contract  (pVV)  and/or  the right to  rescind  this  Agreement
     (Rucktritt) and/or to withdraw from this Agreement  (Wandlung).  The right
     to rescind set out in Section 8.7 shall remain unaffected.

                           Parent Company Guarantee


In  consideration  of the  Sellers  entering  into  this  Agreement,  Guarantor
unconditionally  and  irrevocably  guarantees  as a continuing  obligation  the
proper and punctual  performance by Purchaser of all its  obligations  under or

10.1 The Parties  acknowledge and agree that the  transactions  contemplated by
     this Agreement  shall be notified to the Federal Cartel Office on the date
     of this  Agreement  or, at the latest,  on the first day after the date of
     this Agreement on which banks are opened for general  business in Germany.
     Purchaser  undertakes in connection  with the condition  precedent set out
     in Section 3.2 above to use its best  endeavours  to obtain  consent  from
     the  Federal  Cartel  Office  to the  transactions  contemplated  by  this
     Agreement  as soon as  possible  after  the  date of this  Agreement.  The
     Parties  agree to  promptly  provide to each other  such  information  and
     assistance as any of them may  reasonably  request in connection  with the
     notification and filing and the progress thereof.


10.2 The primary  responsibility  for the  necessary  filings  with the Federal
     Cartel Office in relation to all matters  contemplated  by this  Agreement
     or arising  therefrom shall lie with Purchaser rather than Seller 1 and/or
     Seller 2; however Purchaser shall:


     (i)   before  sending  any  communication   and/or  documentation  to  the
           Federal Cartel Office consult with Seller 1 in relation thereto;




                                      171


     (ii)  promptly  provide to the Federal  Cartel Office such  information as
           the Federal  Cartel  Office may  require in relation  thereto to the
           extent that it lies within the control of  Purchaser to provide such
           information  without breaching any of Sellers' or third party rights
           in relation to confidential information; and


     (iii) provide to Seller 1 copies of all  correspondence  sent by Purchaser
           to or  received  by  Purchaser  from the  Federal  Cartel  Office in
           relation thereto.


10.3 Each of Sellers  shall have the right in its absolute  discretion  to join
     the notification submitted by Purchaser to the Federal Cartel Office.


10.4 In the event that the  condition  precedent  set out in Section  3.2 above
     has not been  fulfilled by February  15,  2001,  Seller 1 shall for and on
     behalf of Sellers be entitled to rescind  this  Agreement  with  immediate
     effect by written  declaration to Purchaser;  provided however that Seller
     1 shall  not  exercise  such  right if the  delay is such  that a  prudent
     business man in good faith could  reasonably be expected to continue to be
     bound  by this  Agreement.  This  shall  be  deemed  to be the case if the
     Federal  Cartel Office has not indicated to any of the Parties that it has
     serious concerns to clear the transaction contemplated by this Agreement.

           Seller 1 shall  without the  consent of any of the other  Parties be
           entitled  to produce  tombstones  in  relation  to the  transactions
